Involving young researchers in the scientific process, and allowing them to gain scientific experience, are important issues for scientific development. The International Conference for Students and Young Scientists ''Modern Technique and Technologies'' is one of a number of scientific events, held at National Research Tomsk Polytechnic University aimed at training and forming the scientific elite. During previous years the conference established itself as a serious scientific event at an international level, attracting members which annually number about 400 students and young scientists from Russia and near and far abroad. An important indicator of this scientific event is the large number of scientific areas covered, such as power engineering, heat power engineering, electronic devices for monitoring and diagnostics, instrumentation, materials and technologies of new generations, methods of research and diagnostics of materials, automatic control and system engineering, physical methods science and engineering, design and artistic aspects of engineering, social and humanitarian aspects of engineering. The main issues, which are discussed at the conference by young researchers, are connected with analysis of contemporary problems, application of new techniques and technologies, and consideration of their relationship. Over the years, the conference committee has gained a lot of experience in organizing scientific meetings. There are all the necessary conditions: the staff of organizers includes employees of Tomsk Polytechnic University; the auditoriums are equipped with modern demonstration and office equipment; leading scientists are TPU professors; the status of the Tomsk Polytechnic University as a leading research university in Russia also plays an important role. All this allows collaboration between leading scientists from all around the world, who are annually invited to give lectures at the conference. The editorial board expresses gratitude to the Administration of Tomsk Polytechnic University (TPU Rector, Professor P.S. Chubik and Vice Rector for Research and Innovation, Professor A.N. Dyachenko) for financial support of the conference. Also, we heartily thank both chairmen of the conference sections and the organizing committee's members for the great, effective, creative work in organizing and developing the conference as well as a significant contribution to the safeguarding and replenishment of the intellectual potential of Russia.

Cosmology is the study of the origin, size, and evolution of the entire universe. Every culture has developed a cosmology, whether it be based on religious, philosophical, or scientific principles. In this book, the evolution of the scientific understanding of the Universe in Western tradition is traced from the early Greek philosophers to the most modern 21st century view. After a brief introduction to the concept of the scientific method, the first part of the book describes the way in which detailed observations of the Universe, first with the naked eye and later with increasingly complex modern instruments, ultimately led to the development of the ``Big Bang'' theory. The second part of the book traces the evolution of the Big Bang including the very recent observation that the expansion of the Universe is itself accelerating with time.

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

Leisure riding horses: research topics versus the needs of stakeholders.

PubMed

Janczarek, Iwona; Wilk, Izabela

2017-07-01

Horses intended for leisure riding do not undergo any selection and most often retired sports horses or defective horses are chosen, as a low selling price determines their purchase by a leisure riding center. Unfortunately, horses bought at low prices usually have low utility value, are difficult to handle, require a special or individual approach and do not provide satisfaction in riding. However, neither modern horse breeding nor scientific research address the need to breed horses for leisure activities. There is no clear definition of a model leisure horse and criteria or information for its selection are not readily available in scientific publications. A wide spectrum of research methods may be used to evaluate various performance traits in horses intended for leisure activities. The fact that the population of recreational horses and their riders outnumber sporting horses should attract the special attention of scientific research. Their utility traits need to be determined with modern technology and methods in the same way they are for sporting horses. Such a system of evaluation would be very helpful for riders. © 2017 Japanese Society of Animal Science.

Along with the development of science and technology, the basic ability to read, write and count is not enough just to be able to survive in the modern era that surrounded by the products of science and technology. Scientific literacy is an ability that might be added as basic ability for human in the modern era. Recently, Fives et al. developed a new scientific literacy assessment for students, named as SLA (Scientific Literacy Assessment). A pilot study on the achievements of scientific literacy of middle school students in Sumedang using SLA was conducted to investigate the profile scientific literacy achievement of 223 middle school students in Sumedang, and compare the outcomes between genders (159 girls and 64 boys) and school accreditation (A and B) using a quantitative method with descriptive research-school survey. Based on the results, the average achievement of scientific literacy Sumedang middle school students is 45.21 and classified as the low category. The five components of scientific literacy, which is only one component in the medium category, namely science motivation and beliefs, and the four other components are in the low and very low category. Boys have higher scientific literacy, but the differences not statistically significant. Student's scientific literacy in an accredited school is higher than B, and the differences are statistically significant. Recommendation for further are: involve more research subjects, add more number of questions for each indicator, and conduct an independent research for each component.

From experimental imaging techniques to virtual embryology.

Modern embryology increasingly relies on descriptive and functional three dimensional (3D) and four dimensional (4D) analysis of physically, optically, or virtually sectioned specimens. To cope with the technical requirements, new methods for high detailed in vivo imaging, as well as the generation of high resolution digital volume data sets for the accurate visualisation of transgene activity and gene product presence, in the context of embryo morphology, were recently developed and are under construction. These methods profoundly change the scientific applicability, appearance and style of modern embryo representations. In this paper, we present an overview of the emerging techniques to create, visualise and administrate embryo representations (databases, digital data sets, 3-4D embryo reconstructions, models, etc.), and discuss the implications of these new methods on the work of modern embryologists, including, research, teaching, the selection of specific model organisms, and potential collaborators.

Gaffney, J. S.; Marley, N. A.; Environmental Research

2003-01-01

Antoine Lavoisier (1743-1794) is well known as the father of modern chemistry. His work on the chemistry of oxygen and the development of the concept of mass balance lighted the way for future chemists to apply rigorous scientific methods in their work. However, Lavoisier also made considerable contributions to other scientific disciplines, including meteorology and atmospheric science. This paper will survey the life of Antoine Lavoisier and his considerable scientific contributions. We will highlight his work on lightning and his attempts to develop a meteorological network for temperature and humidity measurements to support weather prediction.

Colonizing nature: scientific knowledge, colonial power and the incorporation of India into the modern world-system.

PubMed

Baber, Z

2001-03-01

In this paper, the role of scientific knowledge, institutions and colonialism in mutually co-producing each other is analysed. Under the overarching rubric of colonial structures and imperatives, amateur scientists sought to deploy scientific expertise to expand the empire while at the same time seeking to take advantage of the opportunities to develop their careers as 'scientists'. The role of a complex interplay of structure and agency in the development of modern science, not just in India but in Britain too is analysed. The role of science and technology in the incorporation of South Asian into the modern world system, as well as the consequences of the emergent structures in understanding the trajectory of modern science in post-colonial India is examined. Overall, colonial rule did not simply diffuse modern science from the core to the periphery. Rather the colonial encounter led to the development of new forms of scientific knowledge and institutions both in the periphery and the core.

Universal Cosmic Absolute and Modern Science

NASA Astrophysics Data System (ADS)

Kostro, Ludwik

The official Sciences, especially all natural sciences, respect in their researches the principle of methodic naturalism i.e. they consider all phenomena as entirely natural and therefore in their scientific explanations they do never adduce or cite supernatural entities and forces. The purpose of this paper is to show that Modern Science has its own self-existent, self-acting, and self-sufficient Natural All-in Being or Omni-Being i.e. the entire Nature as a Whole that justifies the scientific methodic naturalism. Since this Natural All-in Being is one and only It should be considered as the own scientifically justified Natural Absolute of Science and should be called, in my opinion, the Universal Cosmic Absolute of Modern Science. It will be also shown that the Universal Cosmic Absolute is ontologically enormously stratified and is in its ultimate i.e. in its most fundamental stratum trans-reistic and trans-personal. It means that in its basic stratum. It is neither a Thing or a Person although It contains in Itself all things and persons with all other sentient and conscious individuals as well, On the turn of the 20th century the Science has begun to look for a theory of everything, for a final theory, for a master theory. In my opinion the natural Universal Cosmic Absolute will constitute in such a theory the radical all penetrating Ultimate Basic Reality and will substitute step by step the traditional supernatural personal Absolute.

2014-10-01

The active involvement of young researchers in scientific processes and the acquisition of scientific experience by gifted youth currently have a great value for the development of science. One of the research activities of National Research Tomsk Polytechnic University, aimed at the preparing and formation of the next generation of scientists, is the International Conference of Students and Young Scientists ''Modern Techniques and Technologies'', which was held in 2014 for the twentieth time. Great experience in the organization of scientific events has been acquired through years of carrying the conference. There are all the necessary resources for this: a team of organizers - employees of Tomsk Polytechnic University, premises provided with modern office equipment and equipment for demonstration, and leading scientists - professors of TPU, as well as the status of the university as a leading research university in Russia. This way the conference is able to attract world leading scientists for the collaboration. For the previous years the conference proved itself as a major scientific event at international level, which attracts more than 600 students and young scientists from Russia, CIS and other countries. The conference provides oral plenary and section reports. The conference is organized around lectures, where leading Russian and foreign scientists deliver plenary presentations to young audiences. An important indicator of this scientific event is the magnitude of the coverage of scientific fields: energy, heat and power, instrument making, engineering, systems and devices for medical purposes, electromechanics, material science, computer science and control in technical systems, nanotechnologies and nanomaterials, physical methods in science and technology, control and quality management, design and technology of artistic materials processing. The main issues considered by young researchers at the conference were related to the analysis of contemporary problems using new techniques and application of new technologies.

Groff, Katherine; Brown, Jeffrey; Clippinger, Amy J

2015-12-01

Affinity reagents are essential tools in both basic and applied research; however, there is a growing concern about the reproducibility of animal-derived monoclonal antibodies. The need for higher quality affinity reagents has prompted the development of methods that provide scientific, economic, and time-saving advantages and do not require the use of animals. This review describes two types of affinity reagents, recombinant antibodies and aptamers, which are non-animal technologies that can replace the use of animal-derived monoclonal antibodies. Recombinant antibodies are protein-based reagents, while aptamers are nucleic-acid-based. In light of the scientific advantages of these technologies, this review also discusses ways to gain momentum in the use of modern affinity reagents, including an update to the 1999 National Academy of Sciences monoclonal antibody production report and federal incentives for recombinant antibody and aptamer efforts. In the long-term, these efforts have the potential to improve the overall quality and decrease the cost of scientific research. Copyright © 2015 Elsevier Inc. All rights reserved.

[Reflexology--nothing in common with scientific naturopathic treatments].

PubMed

Heide, M; Heide, M H

2009-09-01

A host of alternative treatment methods are sold to us as reputable science on the "supermarket of naturopathy" nowadays. "Foot zone therapy", also known as "reflexology" is one of them. Advocates of reflexology claim that certain zones of the feet are linked to internal organs; that "energy forces" run throughout the human body. According to the teachings of Ayurveda and Yoga, a network of more than 72,000 nerve tracts (energy tracts = meridians) is linked to a single, tiny point on the feet, where the energy ends. In reality, however, reflexology is an unconventional, alternative, paramedical and esoterical "outsider" method that has nothing in common with serious naturopathic treatments. Any scientific value to reflexology is to be denied. As opposed to reflexology, genuine, scientifically acknowledged naturopathic methods are not an alternative, but a supplement to modern medicine.

Hindu Responses to Darwinism: Assimilation and Rejection in a Colonial and Post-Colonial Context

NASA Astrophysics Data System (ADS)

MacKenzie Brown, C.

2010-06-01

Hindu responses to Darwinism, like Christian, have run the gamut from outright rejection to fairly robust but limited accommodations of the Darwinian perspective. Despite certain features of Hindu thought such as the enormous time-scales of traditional cosmogonies that may suggest considerable affinity with modern notions of organic evolution, more often than not traditional assumptions have worked against deep engagement with Darwinism, allowing only for superficial assimilation at best. Three fundamental factors have affected Hindu responses to Darwinism: the great diversity within the tradition spanning evolutionist and creationist perspectives, the encounter with Darwinism in the late nineteenth century as part of an alien culture, and the fact that this encounter occurred within a colonial context. This essay explores the complex interactions of these three factors, beginning with the diversity within the ancient and classical cosmological traditions, followed by consideration of colonial developments and the emergence of four representative Hindu approaches to Darwinism: Modern Vedic Evolutionism, Anthropic Vedic Evolutionism, Reactionary Vedic Evolutionism, and Modern Vedic Creationism. The essay concludes by discussing various epistemological issues in the attempts of modern Hindu apologists to legitimize Vedic world views. These issues include the appeal to modern science to confirm traditional ideals and values, while simultaneously subordinating scientific method to spiritual means of knowledge, or rejecting scientific methodology with its inbuilt skepticism entirely.

Reasoning About Nature: Graduate students and teachers integrating historic and modern science in high school math and science classes

Graduate students and faculty at East Carolina University are working with area high schools to address the common science and mathematics deficiencies of many high school students. Project RaN (Reasoning about Nature), an interdisciplinary science/math/education research project, addresses these deficiencies by focusing on the history of science and the relationship between that history and modern scientific thought and practice. The geological sciences portion of project RaN has three specific goals: (1) to elucidate the relationships among the history of scientific discovery, the geological sciences, and modern scientific thought; (2) to develop, and utilize in the classroom, instructional modules that are relevant to the modern geological sciences curriculum and that relate fundamental scientific discoveries and principles to multiple disciplines and to modern societal issues; and (3) to use these activity-based modules to heighten students’ interest in science disciplines and to generate enthusiasm for doing science in both students and instructors. The educational modules that result from this linkage of modern and historical scientific thought are activity-based, directly related to the National Science Standards for the high school sciences curriculum, and adaptable to fit each state’s standard course of study for the sciences and math. They integrate historic sciences and mathematics with modern science, contain relevant background information on both the concept(s) and scientist(s) involved, present questions that compel students to think more deeply (both qualitatively and quantitatively) about the subject matter, and include threads that branch off to related topics. Modules on topics ranging from the density to cladistics to Kepler’s laws of planetary motion have been developed and tested. Pre- and post-module data suggest that both students and teachers benefit from these interdisciplinary historically based classroom experiences.

Mayer, V. V.; Varaksina, E. I.

2014-11-01

Students receive a more complete conception of scientific cognition methods if they reproduce fundamentally important historical investigations on their own. Ohm’s investigation realized in 1826 is one of these. This paper presents a simple and accessible experimental unit, in which Ohm’s ideas are implemented with the help of modern means. The unit includes a differential copper/constantan thermocouple, a solenoid, a compass and a spirit lamp. Doing the experiment, students investigate the dependence of current on the electromotive force of the source, source resistance and load resistance.

Cerebral localization in the nineteenth century--the birth of a science and its modern consequences.

PubMed

Steinberg, David A

2009-07-01

Although many individuals contributed to the development of the science of cerebral localization, its conceptual framework is the work of a single man--John Hughlings Jackson (1835-1911), a Victorian physician practicing in London. Hughlings Jackson's formulation of a neurological science consisted of an axiomatic basis, an experimental methodology, and a clinical neurophysiology. His axiom--that the brain is an exclusively sensorimotor machine--separated neurology from psychiatry and established a rigorous and sophisticated structure for the brain and mind. Hughlings Jackson's experimental method utilized the focal lesion as a probe of brain function and created an evolutionary structure of somatotopic representation to explain clinical neurophysiology. His scientific theory of cerebral localization can be described as a weighted ordinal representation. Hughlings Jackson's theory of weighted ordinal representation forms the scientific basis for modern neurology. Though this science is utilized daily by every neurologist and forms the basis of neuroscience, the consequences of Hughlings Jackson's ideas are still not generally appreciated. For example, they imply the intrinsic inconsistency of some modern fields of neuroscience and neurology. Thus, "cognitive imaging" and the "neurology of art"--two topics of modern interest--are fundamentally oxymoronic according to the science of cerebral localization. Neuroscientists, therefore, still have much to learn from John Hughlings Jackson.

Zilsel's thesis on the artisanal origins of modern science remains one of the most original proposals about the emergence of scientific modernity. We propose to inspect the scientific developments in Iberia in the early modern period using Zilsel's ideas as a guideline. Our purpose is to show that his ideas illuminate the situation in Iberia but also that the Iberian case is a remarkable illustration of Zilsel's thesis. Furthermore, we argue that Zilsel's thesis is essentially a sociological explanation that cannot be applied to isolated cases; its use implies global events that involve extended societies over large periods of time.

Partners in Earth System Science: a Field, Laboratory and Classroom Based Professional Development Program for K-12 Teachers Designed to Build Scientific and Pedagogical Understandings of Teaching Climate Change.

The purpose of the Partners in Earth System Science summer and academic year professional development program for Ohio K-12 teachers is to build their understandings of the scientific observations, methods and resources that scientists use when studying past and present climate change. Participants then use these tools to develop inquiry-based activities to teach their K-12 students how the scientific method and data are used to understand the effects of global climate change. The summer portion of the program takes teachers from throughout Ohio to the Duke University Marine Laboratory in Beaufort, North Carolina. There they engage in a physical and biological exploration of the modern and ancient ocean. For example, they collect samples of sediment and test water samples collected from modern coastal environments and connect their findings with evidence of the fauna living in those environments. Then, using observations from the geological record of the Eocene through Pleistocene sediments exposed in eastern North Carolina and inferences from observations made from the modern ocean they seek to answer scientifically testable questions regarding the physical and biological characteristics of the ocean during Cenozoic climate change events. During the academic year participants connect with each other and project faculty online to support the development of inquiry based science activities for their K-12 students. These activities focus on how evidence and observations such as outcrop extent, sediment type and biological assemblages can be used to infer past climates. The activities are taught in participant's classrooms and discussed with other participants in an online discussion space. Assessment of both teachers and K-12 students document significant positive changes in science knowledge, their confidence in being able to do science and a clearer understanding of how oceans are impacted by global climate change.

The article presents a survey of Russian researchers' synchronous international scientific mobility as an element of the global system of scientific labor market. Synchronous international scientific mobility is a simultaneous holding of scientific positions in institutions located in different countries. The study explores bibliometric data from the Web of Science Core Collection and socio-economic indicators for 56 countries. In order to examine international scientific mobility, we use a method of affiliations. The paper introduces a model of synchronous international scientific mobility. It enables to specify country's involvement in the international division of scientific labor. Synchronous international scientific mobility is a modern form of the international division of labor in science. It encompasses various forms of part-time, temporary and remote employment of scientists. The analysis reveals the distribution of Russian authors in the space of affiliations, and directions of upward/downward international scientific mobility. The bibliometric characteristics of mobile authors are isomorphic to those of receiver country authors. Synchronous international scientific mobility of Russian authors is determined by differences in scientific impacts between receiver and donor countries.

Intricacies of modern supercomputing illustrated with recent advances in simulations of strongly correlated electron systems

NASA Astrophysics Data System (ADS)

Schulthess, Thomas C.

2013-03-01

The continued thousand-fold improvement in sustained application performance per decade on modern supercomputers keeps opening new opportunities for scientific simulations. But supercomputers have become very complex machines, built with thousands or tens of thousands of complex nodes consisting of multiple CPU cores or, most recently, a combination of CPU and GPU processors. Efficient simulations on such high-end computing systems require tailored algorithms that optimally map numerical methods to particular architectures. These intricacies will be illustrated with simulations of strongly correlated electron systems, where the development of quantum cluster methods, Monte Carlo techniques, as well as their optimal implementation by means of algorithms with improved data locality and high arithmetic density have gone hand in hand with evolving computer architectures. The present work would not have been possible without continued access to computing resources at the National Center for Computational Science of Oak Ridge National Laboratory, which is funded by the Facilities Division of the Office of Advanced Scientific Computing Research, and the Swiss National Supercomputing Center (CSCS) that is funded by ETH Zurich.

Travel into a fairy land: a critique of modern qualitative and mixed methods psychologies.

PubMed

Toomela, Aaro

2011-03-01

In this article modern qualitative and mixed methods approaches are criticized from the standpoint of structural-systemic epistemology. It is suggested that modern qualitative methodologies suffer from several fallacies: some of them are grounded on inherently contradictory epistemology, the others ask scientific questions after the methods have been chosen, conduct studies inductively so that not only answers but even questions are often supposed to be discovered, do not create artificial situations and constraints on study-situations, are adevelopmental by nature, study not the external things and phenomena but symbols and representations--often the object of studies turns out to be the researcher rather than researched, rely on ambiguous data interpretation methods based to a large degree on feelings and opinions, aim to understand unique which is theoretically impossible, or have theoretical problems with sampling. Any one of these fallacies would be sufficient to exclude any possibility to achieve structural-systemic understanding of the studied things and phenomena. It also turns out that modern qualitative methodologies share several fallacies with the quantitative methodology. Therefore mixed methods approaches are not able to overcome the fundamental difficulties that characterize mixed methods taken separately. It is proposed that structural-systemic methodology that dominated psychological thought in the pre-WWII continental Europe is philosophically and theoretically better grounded than the other methodologies that can be distinguished in psychology today. Future psychology should be based on structural-systemic methodology.

Descartes' dreams.

PubMed

Withers, Robert

2008-11-01

René Descartes is often regarded as the 'father of modern philosophy'. He was a key figure in instigating the scientific revolution that has been so influential in shaping our modern world. He has been revered and reviled in almost equal measure for this role; on the one hand seen as liberating science from religion, on the other as splitting soul from body and man from nature. He dates the founding of his philosophical methods to the night of 10(th) November 1619 and in particular to three powerful dreams he had that night. This article utilizes Descartes' own interpretations of the dreams, supported by biographical material, as well as contemporary neuroscientific and psychoanalytic theory, to reach a new understanding of them. It is argued that the dreams can be understood as depicting Descartes' personal journey from a state of mind-body dissociation to one of mind-body deintegration. This personal journey may have implications for a parallel journey from Renaissance to modern culture and from modernity to post-modern culture.

Mesmer minus magic: hypnosis and modern medicine.

PubMed

Spiegel, David

2002-10-01

The implications and effects of the French commission that passed judgment on Mesmer's work is examined in light of the pioneering role of hypnosis as the first Western conception of a psychotherapy, the ancient philosophical debate between idealism and empiricism, and the conflict in modern medicine between biotechnological emphasis on cure and the need for care as many previously terminal illnesses are converted to chronic diseases. The panel's report is interpreted as negative about the literal theory of animal magnetism but actually supportive of the potential therapeutic power of suggestion and "positive thinking." This aspect of hypnosis is described as a forerunner of modern cognitive therapies of depression and other illnesses. The panel exerted a constructive effect in applying scientific method and rigorous evaluation to hypnotic treatment, an application of Enlightenment philosophy that presaged the Flexner era in modern medicine. Both hypnosis and medicine ultimately benefited.

Moving towards the goals of FP2020 - classifying contraceptives.

Festin, Mario Philip R; Kiarie, James; Solo, Julie; Spieler, Jeffrey; Malarcher, Shawn; Van Look, Paul F A; Temmerman, Marleen

2016-10-01

With the renewed focus on family planning, a clear and transparent understanding is needed for the consistent classification of contraceptives, especially in the commonly used modern/traditional system. The World Health Organization Department of Reproductive Health and Research and the United States Agency for International Development (USAID) therefore convened a technical consultation in January 2015 to address issues related to classifying contraceptives. The consultation defined modern contraceptive methods as having a sound basis in reproductive biology, a precise protocol for correct use and evidence of efficacy under various conditions based on appropriately designed studies. Methods in country programs like Fertility Awareness Based Methods [such as Standard Days Method (SDM) and TwoDay Method], Lactational Amenorrhea Method (LAM) and emergency contraception should be reported as modern. Herbs, charms and vaginal douching are not counted as contraceptive methods as they have no scientific basis in preventing pregnancy nor are in country programs. More research is needed on defining and measuring use of emergency contraceptive methods, to reflect their contribution to reducing unmet need. The ideal contraceptive classification system should be simple, easy to use, clear and consistent, with greater parsimony. Measurement challenges remain but should not be the driving force to determine what methods are counted or reported as modern or not. Family planning programs should consider multiple attributes of contraceptive methods (e.g., level of effectiveness, need for program support, duration of labeled use, hormonal or nonhormonal) to ensure they provide a variety of methods to meet the needs of women and men.

In the recent years the amount of soil data available increased importantly. This facilitated the production of better and accurate maps, important for sustainable land management (Pereira et al., 2017). Despite these advances, the human knowledge is extremely important to understand the natural characteristics of the landscape. The knowledge accumulated and transmitted generation after generation is priceless, and should be considered as a valuable data source for soil mapping and modelling. The local knowledge and wisdom can complement the new advances in soil analysis. In addition, farmers are the most interested in the participation and incorporation of their knowledge in the models, since they are the end-users of the study that soil scientists produce. Integration of local community's vision and understanding about nature is assumed to be an important step to the implementation of decision maker's policies. Despite this, many challenges appear regarding the integration of local and scientific knowledge, since in some cases there is no spatial correlation between folk and scientific classifications, which may be attributed to the different cultural variables that influence local soil classification. The objective of this work is to review how modern soil methods incorporated local knowledge in their models.

Introduction: Science is constantly being developed which leads to both positive and negative changes in public health and the environment. One of the results of scientific progress is introduction of food based on genetically modified organisms whose effects on human health, to date, remain scantily studied and are ambiguous. The aim: to determine how human health can be influenced by food production based on genetically modified organisms. Materials and methods: international acts, data of international organizations and conclusions of scientists have been examined and used in the study. The article also summarizes information from scientific journals and monographs from a medical and legal point of view with scientific methods. This article is based on dialectical, comparative, analytic, synthetic and comprehensive research methods. Conclusions: Genetically modified organisms are specific human-made organisms being a result of using modern biotechnology techniques. They have both positive and negative effects on human health and the environment. The main disadvantage is not sufficient study of them in various spheres of public life.

The origin of scientific neurology and its consequences for modern and future neuroscience.

Steinberg, David A

2014-01-01

John Hughlings Jackson (1835-1911) created a science of brain function that, in scope and profundity, is among the great scientific discoveries of the 19th century. It is interesting that the magnitude of his achievement is not completely recognized even among his ardent admirers. Although thousands of practitioners around the world use the clinical applications of his science every day, the principles from which bedside neurology is derived have broader consequences-for modern and future science-that remain unrecognized and unexploited. This paper summarizes the scientific formalism that created modern neurology, demonstrates how its direct implications affect a current area of neuroscientific research, and indicates how Hughlings Jackson's ideas form a path toward a novel solution to an important open problem of the brain and mind.

To create a comparative referential system for syndrome classification study by viewing from the thinking characteristics of TCM on syndrome differentiation dependent therapy (SDDT), through analyzing the thinking process of SDDT, and the basic features of disease, syndrome and prescription, combining the basic principles of modern evidence-based medicine and feasibility of establishing integrative disease-syndrome animal model. The practice of creating a comparative referential system based on clinical efficacy of prescription was discussed around syndrome pathogenesis and its relationship with disease and prescription, which was one of the important scientific problems in TCM syndrome study. The authors hold that, it may be one of the available approaches for the present study on integration of disease with syndrome by way of insisting on the thinking pathway of stressing the characteristics of TCM and intermerging with modern scientific design; on taking the efficacy of prescription as the comparative reference system to accumulate and improve unceasingly according to the TCM method of syndrome diagnosis inferred from effect of prescription with reverse thought (i.e., to differentiate syndrome from the effect of prescription), and thus build up the syndrome diagnostic standard on the solid clinical and scientific base.

A Modern Series Of Cinematographic Lenses: From Concept To Product

NASA Astrophysics Data System (ADS)

Neil, lain A.

1988-06-01

In the past photographic "taking" lenses and, in particular, those for the motion picture industry i.e. cinematographic lenses have had a mixed career due to inconsistencies between the processes of lens design, manufacture, testing and calibration and practical assessment in the customer domain. Usually these inconsistencies can be attributed to differences between the comparison of, a lens design "scientifically" made and final evaluation in an "artistic" manner. The following paper addresses the processes of lens design, manufacture, testing and calibration using a combination of acquired practical experience and modern test and calibration methods. Various performance aspects are separately addressed and considered in terms of different means of measurement.

Functional structure of modern gerontodietology, its scientific-methodical bases, terminological features are presented. Composition and features of healthy nutrition of elderly people is described in details, methods of its optimization and individualization are given. Notions of geriatric dietotherapy, its principal difference from curative nutrition of patients of other ages are described. Large section of the article is devoted to the modern problems of prophylactic gerontodietology, intended more for persons with high risk of early aging than for elderly persons. Theoretic basis and methodological contents of prophylactic gerontodietology are presented; practical recommendations on dietetic means to prevent intensive development of involution processes and organic pathology in the body are described.

Scientific discovery as a combinatorial optimisation problem: How best to navigate the landscape of possible experiments?

PubMed Central

Kell, Douglas B

2012-01-01

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

The birth of experimental psychology in Germany between psychophysical methods and physiological theories.

PubMed

Sinatra, Maria

2006-01-01

In 1879 Wundt's laboratory of psychology was opened in Leipzig, and it has been the landmark ever since for the beginning of modern experimental psychology. Its founder, Wilhelm Maximilian Wundt, was the first to successfully demarcate the areas of scientific psychology as being distinct from either physiology or philosophy, thus guaranteeing the survival of psychology, which was regarded as an autonomous discipline set upon a secure institutional framework. This paper attempts to clarify the basic facts and concepts related to the roots of scientific psychology in Germany, i.e., the context in which the "Founding Father" worked, as well as of those predecessors who proposed the topics and apparatus of his laboratory. Attention will be paid in particular to the psychophysical methods of Weber and Fechner, especially in regard to colour perception. In this context, an outline is presented of the history of reaction time experiments in astronomy, physiology, and psychology, and of the role played by the scientific instruments. It is shown how the methodology of physics and physiology contributed to the emancipation of scientific psychology and to the formation of its orientation.

The application of new information technologies will have a lasting impact on the physicians' working environment. Not only will classic learning methods change, but also ways of communication and strategies to find relevant information. This survey is designed to demonstrate current methods of and demand for continuing medical education and communication. 110 participating physicians (26% female, 74% male) in nine different regional hospitals were asked regarding "continuing medical education", "communication" and "use of computerized technology". Most physicians regard their colleagues, scientific journals, textbooks and scientific meetings as most useful. The internet, scientific staff at research institutions and pharmaceutical representatives were valued as less useful. Physicians regarded scientific basis, speed and user-friendliness as the most important features of potential data and knowledge sources. Case specificity, German language and interactivity were viewed as less important. Most physicians expressed a growing need for education regarding use of e-mail as a communication tool and internet research techniques. Continuing medical education is in strong demand. The successful introduction of modern information technologies into physicians' daily work may and should be enhanced by specifically tailored training courses.

Pastoral care in hospitals: a literature review.

Proserpio, Tullio; Piccinelli, Claudia; Clerici, Carlo Alfredo

2011-01-01

This literature review investigates the potential contribution of the pastoral care provided in hospitals by hospital chaplains, as part of an integrated view of patient care, particularly in institutions dealing with severe disease. A search was conducted in the Medline database covering the last 10 years. Ninety-eight articles were considered concerning the modern hospital chaplains' relationships and the principal procedures and practices associated with their roles, i.e., their relations with the scientific world, with other religious figures in the community, with other faiths and religious confessions, with other public health professionals and operators, with colleagues in professional associations and training activities, and with the hospital organization as a whole, as well as their patient assessment activities and the spiritual-religious support they provide, also for the patients' families. Improvements are needed on several fronts to professionalize the pastoral care provided in hospitals and modernize the figure of the hospital chaplain. These improvements include better relations between modern chaplains and the hospital organization and scientific world; more focus on a scientific approach to their activities and on evaluating the efficacy of pastoral care activities; greater clarity in the definition of the goals, methods and procedures; the design of protocols and a stance on important ethical issues; respect for the various faiths, different cultures and both religious and nonreligious or secularized customs; greater involvement in the multidisciplinary patient care teams, of which the hospital chaplains are an integral part; stronger integration with public health operators and cooperation with the psychosocial professions; specific training on pastoral care and professional certification of chaplains; and the development of shared ethical codes for the profession.

Incurable suffering from the "hiatus theoreticus"? Some epistemological problems in modern medicine and the clinical relevance of philosophy of medicine.

PubMed

Paul, N

1998-06-01

Up to now neither the question, whether all theoretical medical knowledge can at least be described as scientific, nor the one how exactly access to the existing scientific and theoretical medical knowledge during clinical problem-solving is made, has been sufficiently answered. Scientific theories play an important role in controlling clinical practice and improving the quality of clinical care in modern medicine on the one hand, and making it vindicable on the other. Therefore, the vagueness of unexplicit interrelations between medicine's stock of knowledge and medical practice appears as a gap in the theoretical concept of modern medicine which can be described as "Hiatus theoreticus" in the anatomy of medicine. A central intention of the paper is to analyze the role of philosophy of medicine for the clarification of the theoretical basis of medical practice. Clinical relevance and normativity in the sense of modern theory of science are suggested as criteria to establish a differentiation between philosophy of medicine as a primary medical discipline and the application of general philosophy in medicine.

For the greater credibility: Jesuit science and education in modern Portugal (1858-1910).

Malta Romeiras, Francisco

2018-03-01

Upon the restoration of the Society of Jesus in Portugal in 1858, the Jesuits founded two important colleges that made significant efforts in the promotion of hands-on experimental teaching of the natural sciences. At the Colégio de Campolide (Lisbon, 1858-1910) and the Colégio de São Fiel (Louriçal do Campo, 1863-1910) the Jesuits created modern chemistry and physics laboratories, organized significant botanical, zoological and geological collections, promoted scientific expeditions with their students to observe eclipses and to collect novel species of animals and plants, and engaged in original research work in physics, botany, and zoology. The successful implementation of modern scientific practices gained these colleges public recognition as the most prominent secondary institutions in nineteenth-century Portugal, and this made a major contribution to countering the widespread and commonly accepted anti-Jesuit accusations of obscurantism and scientific backwardness.

A long history of breakdowns: A historiographical review.

PubMed

Margócsy, Dániel

2017-06-01

The introduction to this special issue argues that network breakdowns play an important and unacknowledged role in the shaping and emergence of scientific knowledge. It focuses on transnational scientific networks from the early modern Republic of Letters to 21st-century globalized science. It attempts to unite the disparate historiography of the early modern Republic of Letters, the literature on 20th-century globalization, and the scholarship on Actor-Network Theory. We can perceive two, seemingly contradictory, changes to scientific networks over the past four hundred years. At the level of individuals, networks have become increasing fragile, as developments in communication and transportation technologies, and the emergence of regimes of standardization and instrumentation, have made it easier both to create new constellations of people and materials, and to replace and rearrange them. But at the level of institutions, collaborations have become much more extensive and long-lived, with single projects routinely outlasting even the arc of a full scientific career. In the modern world, the strength of institutions and macro-networks often relies on ideological regimes of standardization and instrumentation that can flexibly replace elements and individuals at will.

We teach an experimental college-level course, directed toward elementary education majors, emphasizing "hands-on" activities that can be easily applied to the elementary classroom. This course, Physics 240: "The Sun-Earth Connection" includes various ways to study selected topics in physics, earth science, and basic astronomy. Our lesson plans and EPO materials make extensive use of NASA imagery and cover topics about magnetism, the solar photospheric, chromospheric, coronal spectra, as well as earth science and climate. In addition we are developing and will cover topics on ecosystem structure, biomass and water on Earth. We strive to free the non-science undergraduate from the "fear of science" and replace it with the excitement of science such that these future teachers will carry this excitement to their future students. Hands-on experiments, computer simulations, analysis of real NASA data, and vigorous seminar discussions are blended in an inquiry-driven curriculum to instill confident understanding of basic physical science and modern, effective methods for teaching it. The course also demonstrates ways how scientific thinking and hands-on activities could be implemented in the classroom. We have designed this course to provide the non-science student a confident basic understanding of physical science and modern, effective methods for teaching it. Most of topics were selected using National Science Standards and National Mathematics Standards that are addressed in grades K-8. The course focuses on helping education majors: 1) Build knowledge of scientific concepts and processes; 2) Understand the measurable attributes of objects and the units and methods of measurements; 3) Conduct data analysis (collecting, organizing, presenting scientific data, and to predict the result); 4) Use hands-on approaches to teach science; 5) Be familiar with Internet science teaching resources. Here we share our experiences and challenges we face while teaching this course.

Collective credit allocation in science

Shen, Hua-Wei; Barabási, Albert-László

2014-01-01

Collaboration among researchers is an essential component of the modern scientific enterprise, playing a particularly important role in multidisciplinary research. However, we continue to wrestle with allocating credit to the coauthors of publications with multiple authors, because the relative contribution of each author is difficult to determine. At the same time, the scientific community runs an informal field-dependent credit allocation process that assigns credit in a collective fashion to each work. Here we develop a credit allocation algorithm that captures the coauthors’ contribution to a publication as perceived by the scientific community, reproducing the informal collective credit allocation of science. We validate the method by identifying the authors of Nobel-winning papers that are credited for the discovery, independent of their positions in the author list. The method can also compare the relative impact of researchers working in the same field, even if they did not publish together. The ability to accurately measure the relative credit of researchers could affect many aspects of credit allocation in science, potentially impacting hiring, funding, and promotion decisions.

Four Bad Habits of Modern Psychologists

Four data sets from studies included in the Reproducibility Project were re-analyzed to demonstrate a number of flawed research practices (i.e., “bad habits”) of modern psychology. Three of the four studies were successfully replicated, but re-analysis showed that in one study most of the participants responded in a manner inconsistent with the researchers’ theoretical model. In the second study, the replicated effect was shown to be an experimental confound, and in the third study the replicated statistical effect was shown to be entirely trivial. The fourth study was an unsuccessful replication, yet re-analysis of the data showed that questioning the common assumptions of modern psychological measurement can lead to novel techniques of data analysis and potentially interesting findings missed by traditional methods of analysis. Considered together, these new analyses show that while it is true replication is a key feature of science, causal inference, modeling, and measurement are equally important and perhaps more fundamental to obtaining truly scientific knowledge of the natural world. It would therefore be prudent for psychologists to confront the limitations and flaws in their current analytical methods and research practices. PMID:28805739

1986-01-01

This volume presents insights into the indigenous architectural forms in hot arid climates. The author presents his extensive research on climate control, particularly in the Middle East, to demonstrate the advantages of many locally available building materials and traditional building methods. He suggests improved uses of natural energy that can bridge the gap between traditional achievements and modern needs. He argues that various architectural forms in these climates have evolved intuitively from scientifically valid concepts. Such forms combine comfort and beauty, social and physical functionality. He discusses that in substituting modern materials, architects sometimes have ignored the environmental context ofmore » traditional architecture. As a result, individuals may find themselves physically and psychologically uncomfortable in modern structures. His approach, informed by a sensitive humanism, demonstrates the ways in which traditional architectural forms can be of use in solving problems facing contemporary architecture, in particular the critical housing situation in the Third World.« less

2010-01-01

The development of the anatomical-clinical method was a huge advance for modern medicine since it revealed a new approach to understanding diagnostic procedures. This change in medical thinking towards a more scientific basis has gradually evolved over several centuries, reaching its brilliant zenith with the contributions of the French school. There are certain similarities between the guidelines of the anatomical-clinical method and René Descartes' philosophical principles, so it is fair to consider him as one of the major precursors in this new line of thinking that definitely influenced the historical course of medicine.

Examining the impact of sexism on evaluations of social scientific evidence in discrimination litigation.

PubMed

Kim, Anita; Tidwell, Natasha

2014-12-01

The present 2 studies involved undergraduate participants and investigated whether various types of sexism and other correlated predictors, such as political conservatism and scientific discounting, can predict people's evaluations of social science research on sex stereotypes, sexism, and sex discrimination. In Study 1, participants high in hostile sexism, scientific discounting, and/or political conservatism were more critical of scientific studies that provided evidence for sexism than identical studies showing null results. Study 2 showed that participants high in modern sexism, hostile sexism, and political conservatism evaluated social scientific studies more negatively; in addition, assessments of social scientific evidence quality mediated the effect of modern sexism on admissibility ratings (b = -0.15, z = -4.16, p = .00). Overall, these results suggest that sexist beliefs can bias one's judgments of social scientific evidence. Future research should explore whether the same psychological processes operate for judges and jurors as they evaluate the admissibility of evidence and examine ways to attenuate the effect of sexism on evaluations.

Neural data science: accelerating the experiment-analysis-theory cycle in large-scale neuroscience.

PubMed

Paninski, L; Cunningham, J P

2018-06-01

Modern large-scale multineuronal recording methodologies, including multielectrode arrays, calcium imaging, and optogenetic techniques, produce single-neuron resolution data of a magnitude and precision that were the realm of science fiction twenty years ago. The major bottlenecks in systems and circuit neuroscience no longer lie in simply collecting data from large neural populations, but also in understanding this data: developing novel scientific questions, with corresponding analysis techniques and experimental designs to fully harness these new capabilities and meaningfully interrogate these questions. Advances in methods for signal processing, network analysis, dimensionality reduction, and optimal control-developed in lockstep with advances in experimental neurotechnology-promise major breakthroughs in multiple fundamental neuroscience problems. These trends are clear in a broad array of subfields of modern neuroscience; this review focuses on recent advances in methods for analyzing neural time-series data with single-neuronal precision.

Understanding how the brain operates requires understanding how large sets of neurons function together. Modern recording technology makes it possible to simultaneously record the activity of hundreds of neurons, and technological developments will soon allow recording of thousands or tens of thousands. As with all experimental techniques, these methods are subject to confounds that complicate the interpretation of such recordings, and could lead to erroneous scientific conclusions. Here, we discuss methods for assessing and improving the quality of data from these techniques, and outline likely future directions in this field. PMID:27571195

[Problems associated with the prevention of cruelty to animals in modern livestock breeding (author's transl)].

PubMed

Schultze-Petzold, H

1976-01-01

Regulations for the protection of useful animals can be traced to the early history of Law. The reason for such regulations has hardly changed up to the present: the expedient incorporation of the animal into the hierachy of values of the prevailing times. Decisive impulses invariably originated from the legal conception, the need for legal protection as well as from the scientific conceptions of society. The development rarely took a linear course and was not without setbacks. The prevention of cruelty to animals has always been faced with particular conflicting situations. Our pluralistic society with its marked philosophy of profit-making has to face such a problem, in particular as a result of livestock keeping in modern systems. The necessity and legitimacy of a permanent supply of large quantities of high-grade animal foodstuffs to be offered to our present industrial society on a competitive and low-cost basis, have contributed to this development. The public and parliament have for some time been demanding a modern federal act for the prevention of cruelty to animals based on a technical conception allowing also those questions of animal protection related to the present keeping of useful animals to be integrated, thus achieving a gradual balancing of interests. Such an Animal Protection Act came into force on October 1, 1972. On account of its scientific orientation it prompts us to give renewed thought to many present-day ideas about the keeping of animals, especially of useful animals, employing modern systems. With this objective in mind the Act has already strongly influenced the developing international harmonization of provisions for Animal Protection. The problems linked with "Animal Protection/Keeping of Useful Animals" require a harmonization of the ethical, scientific, economic and legal aspects as an indispensable prerequisite. On the basis of expert opinions prepared by a group of specialists of the Federal Ministry of Agriculture on the minimum requirements to be satisfied by modern systems of fowl breeding, the various scientific basic concepts and evaluations are presented. The value of the information yielded by modern research into animal behaviour is emphasized in this connection. Future legal ordinances in accordance with Clause 13, para 1 of the Animal Protection Act of July 24, 1972 for the protection of useful animals kept in modern systems call for a particularly thorough scientific foundation which must also stand up to examination by the courts. The problems to be solved require comprehensive research. An urgent task for the near future will be to give the resolution of these problems a firm scientific base. In addition to the topical approach to the subject "Animal Protection/Keeping of Useful Animals", indications are given for a comprehensive approach which will prove indispensable in the future...

Scientific approach and practical experience for reconstruction of waste water treatment plants in Russia

NASA Astrophysics Data System (ADS)

Makisha, Nikolay; Gogina, Elena

2017-11-01

Protection of water bodies has a strict dependence on reliable operation of engineering systems and facilities for water supply and sewage. The majority of these plants and stations has been constructed in 1970-1980's in accordance with rules and regulations of that time. So now most of them require reconstruction due to serious physical or/and technological wear. The current condition of water supply and sewage systems and facilities frequently means a hidden source of serious danger for normal life support and ecological safety of cities and towns. The article reveals an obtained experience and modern approaches for reconstruction of waste water and sludge treatment plants that proved their efficiency even if applied in limited conditions such as area limits, investments limits. The main directions of reconstruction: overhaul repair and partial modernization of existing facilities on the basis of initial project; - restoration and modernization of existing systems on the basis on the current documents and their current condition; upgrade of waste water treatment plants (WWTPs) performance on the basis of modern technologies and methods; reconstruction of sewage systems and facilities and treatment quality improvement.

2015-09-01

The Visualization Toolkit (VTK) is an open source, permissively licensed, cross-platform toolkit for scientific data processing, visualization, and data analysis. It is over two decades old, originally developed for a very different graphics card architecture. Modern graphics cards feature fully programmable, highly parallelized architectures with large core counts. VTK's rendering code was rewritten to take advantage of modern graphics cards, maintaining most of the toolkit's programming interfaces. This offers the opportunity to compare the performance of old and new rendering code on the same systems/cards. Significant improvements in rendering speeds and memory footprints mean that scientific data can be visualized in greater detail than ever before. The widespread use of VTK means that these improvements will reap significant benefits.

Chai, Cheng-Zhi; Yu, Bo-Yang

2018-06-01

Many classical prescriptions still have superior clinical values nowadays, and their modern studies also have far-reaching scientific research demonstration values. Gegen decoction, a representative prescription for common cold due to wind-cold, can treat primary dysmenorrhea due to cold and dampness, characterized by continuous administration without recurrence. It is not only in accordance with the principle of homotherapy for heteropathy, but also demonstrates the unique feature of traditional Chinese medicine of relieving the primary and secondary symptoms simultaneously. This article aimed to discuss the method and strategy of Gegen decoction study based on the discovery of its novel application in treatment of primary dysmenorrhea and previous research progress of our group. It was assumed that modern medicine and biology studies, as well as chemical research based on biological activity should be used for reference. Principal active ingredients (groups) in Gegen decoction could be accurately and effectively identified, and its possible mechanism in treatment of primary dysmenorrhea could be eventually elucidated as well. Simultaneously, the theoretical and clinical advantages of traditional Chinese medicine were explored in this paper, focusing on the compatibility characteristics of Gegen decoction. The research hypothesis showed the necessity of following the characteristics and advantages of traditional Chinese medicine in the modern research and reflected the importance of basic research based on the clinical efficacy, expecting to provide some ideas and methods for reference for further modern studies of classical prescriptions.

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.

In considering the appropriate use of the terms "science" and "scientific instrument," tracing the history of "mathematical instruments" in the early modern period is offered as an illuminating alternative to the historian's natural instinct to follow the guiding lights of originality and innovation, even if the trail transgresses contemporary boundaries. The mathematical instrument was a well-defined category, shared across the academic, artisanal, and commercial aspects of instrumentation, and its narrative from the sixteenth to the eighteenth century was largely independent from other classes of device, in a period when a "scientific" instrument was unheard of.

Article-level assessment of influence and translation in biomedical research

Santangelo, George M.

2017-01-01

Given the vast scale of the modern scientific enterprise, it can be difficult for scientists to make judgments about the work of others through careful analysis of the entirety of the relevant literature. This has led to a reliance on metrics that are mathematically flawed and insufficiently diverse to account for the variety of ways in which investigators contribute to scientific progress. An urgent, critical first step in solving this problem is replacing the Journal Impact Factor with an article-level alternative. The Relative Citation Ratio (RCR), a metric that was designed to serve in that capacity, measures the influence of each publication on its respective area of research. RCR can serve as one component of a multifaceted metric that provides an effective data-driven supplement to expert opinion. Developing validated methods that quantify scientific progress can help to optimize the management of research investments and accelerate the acquisition of knowledge that improves human health.

A Selective Overview of Variable Selection in High Dimensional Feature Space

PubMed Central

Fan, Jianqing

2010-01-01

High dimensional statistical problems arise from diverse fields of scientific research and technological development. Variable selection plays a pivotal role in contemporary statistical learning and scientific discoveries. The traditional idea of best subset selection methods, which can be regarded as a specific form of penalized likelihood, is computationally too expensive for many modern statistical applications. Other forms of penalized likelihood methods have been successfully developed over the last decade to cope with high dimensionality. They have been widely applied for simultaneously selecting important variables and estimating their effects in high dimensional statistical inference. In this article, we present a brief account of the recent developments of theory, methods, and implementations for high dimensional variable selection. What limits of the dimensionality such methods can handle, what the role of penalty functions is, and what the statistical properties are rapidly drive the advances of the field. The properties of non-concave penalized likelihood and its roles in high dimensional statistical modeling are emphasized. We also review some recent advances in ultra-high dimensional variable selection, with emphasis on independence screening and two-scale methods. PMID:21572976

This article summarizes the outcome of an international workshop organized by the European Partnership for Alternative Approaches to Animal Testing (EPAA) on Modern science for better quality control of medicinal products: Towards global harmonization of 3Rs in biologicals. As regards the safety testing of biologicals, the workshop participants agreed to actively encourage the deletion of abnormal toxicity tests and target animal batch safety tests from all relevant legal requirements and guidance documents (country-specific guidelines, pharmacopoeia monographs, WHO recommendations). To facilitate the global regulatory acceptance of non-animal methods for the potency testing of, e.g., human diphtheria and tetanus vaccines and veterinary swine erysipelas vaccines, international convergence on the scientific principles of the use of appropriately validated in vitro assays for replacing in vivo methods was identified as an overarching goal. The establishment of scientific requirements for new assays was recognized as a further means to unify regulatory approaches in different jurisdictions. It was recommended to include key regulators and manufacturers early in the corresponding discussions. Manufacturers and responsible expert groups, e.g. at the European Directorate for the Quality of Medicines and Health Care of the Council of Europe or the European Medicines Agency, were invited to consider leadership for international collaboration.

dREL: a relational expression language for dictionary methods.

PubMed

Spadaccini, Nick; Castleden, Ian R; du Boulay, Doug; Hall, Sydney R

2012-08-27

The provision of precise metadata is an important but a largely underrated challenge for modern science [Nature 2009, 461, 145]. We describe here a dictionary methods language dREL that has been designed to enable complex data relationships to be expressed as formulaic scripts in data dictionaries written in DDLm [Spadaccini and Hall J. Chem. Inf. Model.2012 doi:10.1021/ci300075z]. dREL describes data relationships in a simple but powerful canonical form that is easy to read and understand and can be executed computationally to evaluate or validate data. The execution of dREL expressions is not a substitute for traditional scientific computation; it is to provide precise data dependency information to domain-specific definitions and a means for cross-validating data. Some scientific fields apply conventional programming languages to methods scripts but these tend to inhibit both dictionary development and accessibility. dREL removes the programming barrier and encourages the production of the metadata needed for seamless data archiving and exchange in science.

Narrative medicine: the modern communication between patient and doctor.

PubMed

Coaccioli, S

2011-01-01

In Modern Medicine the ability to communicate represents a true and unique operative methodology which is the basis of Narrative Medicine. This type of approach does not represent an alternative to the traditional model, but rather expands its boundaries while preserving its scientific base; where the feelings, expectations, and desires of the Patient and his interpretation of the disease, more or less obvious, are read in the broad context in which the Patient himself exhibits. Two principle themes in medical training have by now been clearly identified and can be summarized as follows: the ability to understand and to explain (what to say to the patient) and the ability to listen and to comprehend (how to speak to the patient). In this regard the modern Narrative Medicine is a holistic approach to the complexity of the method known as the most effective and most efficient - not only in patient-centered medicine, but also in the improvement of services rendered to both the individual and society at large.

With the development of the modernization drive of traditional Chinese medicine (TCM) preparations, new-type TCM dosage forms research have become a hot spot in the field. Because of complexity of TCM components as well as uncertainty of material base, there is still not a scientific system for modern TCM dosage forms so far. Modern TCM preparations inevitably take the nature of the multi-component and the general function characteristics of multi-link and multi-target into account. The author suggests building a multiple drug release system for TCM using diverse preparation techniques and drug release methods at levels on the basis the nature and function characteristics of TCM components. This essay expounds elaborates the ideas to build the multiple traditional Chinese medicine release system, theoretical basis, preparation techniques and assessment system, current problems and solutions, in order to build a multiple TCM release system with a view of enhancing the bioavailability of TCM components and provide a new form for TCM preparations.

Quantifying falsifiability of scientific theories

Nemenman, Ilya

I argue that the notion of falsifiability, a key concept in defining a valid scientific theory, can be quantified using Bayesian Model Selection, which is a standard tool in modern statistics. This relates falsifiability to the quantitative version of the statistical Occam's razor, and allows transforming some long-running arguments about validity of scientific theories from philosophical discussions to rigorous mathematical calculations.

Maeda, Y

2001-12-01

How can one characterize modern Europe? This problem is essentially related to the meaning of modern natural science, which was developed during the scientific revolution. Then how did viewpoints change during this revolution? The answer to this question also determined the basic character of modern philosophy. Through the examination of Aristotle's geocentric theory and kinematics, I have come to believe that the defect of Aristotle's was that he concluded that a visible sense image is an actual reflection of the reality as it is. From this point of view, the traditional theory of truth called "correspondence theory" is found to be an insufficient one. Therefore, in this paper I will show that the methodological and philosophical question "How do we see reality among phenomena?" is a very important one. This question is the one Plato struggled with, and also the one which guided Kant. It may be said that this can be seen as a group for a new metaphysics as a basic theory of reality.

PubMed

Svenaeus, Fredrik

2013-02-01

Heidegger's thoughts on modern technology have received much attention in many disciplines and fields, but, with a few exceptions, the influence has been sparse in biomedical ethics. The reason for this might be that Heidegger's position has been misinterpreted as being generally hostile towards modern science and technology, and the fact that Heidegger himself never subjected medical technologies to scrutiny but was concerned rather with industrial technology and information technology. In this paper, Heidegger's philosophy of modern technology is introduced and then brought to bear on medical technology. Its main relevance for biomedical ethics is found to be that the field needs to focus upon epistemological and ontological questions in the philosophy of medicine related to the structure and goal of medical practice. Heidegger's philosophy can help us to see how the scientific attitude in medicine must always be balanced by and integrated into a phenomenological way of understanding the life-world concerns of patients. The difference between the scientific and the phenomenological method in medicine is articulated by Heidegger as two different ways of studying the human body: as biological organism and as lived body. Medicine needs to acknowledge the priority of the lived body in addressing health as a way of being-in-the-world and not as the absence of disease only. A critical development of Heidegger's position can provide us with a criterion for distinguishing the uses of medical technologies that are compatible with such an endeavor from the technological projects that are not.

In the maw of the Ouroboros: an analysis of scientific literacy and democracy

NASA Astrophysics Data System (ADS)

Bang, Lars

2017-10-01

This paper explores the concept of scientific literacy through its relation to democracy and citizenship. Scientific literacy has received international attention in the twenty-first century as demonstrated by the Programme for International Student Assessment survey of 2006. It is no longer just a concept but has become a stated and testable outcome in the science education research community. This paper problematizes the `marriage' between scientific literacy and democracy, particularly the idea that scientific literacy is a presupposed necessity to proper citizenship and awareness of the role of science in modern society. A perusal of the science education literature can provide a history of scientific literacy, as it exists as a research category. Through Gilles Deleuze's notion of the Dogmatic Image of Thought and its relation to a Spinozist understanding of individuation/Becoming, it is argued that scientific literacy is not a recent invention and is problematic in its relation to democracy. This article is thus intended to act more as vehicle to move, stimulate and dramatize thought and potentially reconceptualise scientific literacy, than a comprehensive historical analysis. The concept of scientific literacy has undergone specific transformations in the last two centuries and has been enacted in different manifestations throughout modernity. Here the analysis draws upon Deleuze's reading of Michel Foucault and the notion of the Diagram related to Foucault's oeuvre, and is specifically using Foucault's notion of rationalities as actualized threads or clusters of discourse. The obvious link between science and democracy is an effect of specific rationalities within the epistemological field of science, rather than intrinsic, essential characteristics of science or scientific literacy. There is nothing intrinsic in its function for democracy. Through a case study of the work of Charles W. Eliot and Herbert Spencer and the modern enactment of scientific literacy in contemporary science education, this paper shows the cultural and historical contingencies on which the relation between scientific literacy and democracy has been constructed through a rationality this article calls the Man of Science. The mythical Ouroboros will be used as a Fresh Image of Thought to explore the movements and folds within the discursive formation of Scientific Literacy, the rationality of the Man of Science, and their relation to democracy.

Bim Automation: Advanced Modeling Generative Process for Complex Structures

2017-08-01

The new paradigm of the complexity of modern and historic structures, which are characterised by complex forms, morphological and typological variables, is one of the greatest challenges for building information modelling (BIM). Generation of complex parametric models needs new scientific knowledge concerning new digital technologies. These elements are helpful to store a vast quantity of information during the life cycle of buildings (LCB). The latest developments of parametric applications do not provide advanced tools, resulting in time-consuming work for the generation of models. This paper presents a method capable of processing and creating complex parametric Building Information Models (BIM) with Non-Uniform to NURBS) with multiple levels of details (Mixed and ReverseLoD) based on accurate 3D photogrammetric and laser scanning surveys. Complex 3D elements are converted into parametric BIM software and finite element applications (BIM to FEA) using specific exchange formats and new modelling tools. The proposed approach has been applied to different case studies: the BIM of modern structure for the courtyard of West Block on Parliament Hill in Ottawa (Ontario) and the BIM of Masegra Castel in Sondrio (Italy), encouraging the dissemination and interaction of scientific results without losing information during the generative process.

The beginnings of modern western medicine reach to about 1800 when under the liberating influence of French Revolution observation of diseases was started to follow more scientifically justified criteria. At that time speculative doctrines prevailed, e. g. those set up natural philosopher Schelling. In this context Internist Friedrich Theodor von Frerichs at Berlin Charité University Hospital gained great merits because of his struggle for a scientifically-based experimental clinical medicine.

Emphasizing history in communicating scientific debates

NASA Astrophysics Data System (ADS)

Sherwood, S. C.

2010-12-01

Communication to the public of the reality of anthropogenic climate change has been less successful than many expect. The scientists themselves, the media, special interest groups, or the complexity of modern society are often blamed. However a look at past scientific paradigm shifts, in particular the Copernican revolution and the discovery of relativity, shows close parallels with the modern situation. Common aspects include the gradual formation of a scientific consensus in advance of the public; a politically partisan backlash against the new theory that, paradoxically, occurs after the arrival of conclusive supporting evidence; the prevalence of convincing but invalid pseudo-scientific counterarguments; the general failure of "debates" to increase public acceptance of the scientists' position; and, in the case of the heliocentric solar system, a very long time scale to final public acceptance (> 100 years). Greater emphasis on the lessons from such historical parallels, and on the success so far of consensus predictions of global warming made up to and including the first IPCC report in 1990, might be one useful way of enhancing the public's trust in science and scientists and thereby accelerate acceptance of uncomfortable scientific findings.

Diffusion of knowledge and globalization in the web of twentieth century science

Scientific communication is an essential part of modern science: whereas Archimedes worked alone, Newton (correspondence with Hooke, 1676) acknowledged that “If I have seen a little further, it is by standing on the shoulders of Giants.” How is scientific communication reflected in the patterns of citations in scientific papers? How have these patterns changed in the 20th century, as both means of communication and individual transportation changed rapidly, compared to the earlier post-Newton 18th and 19th centuries? Here we discuss a diffusive model for scientific communications, based on a unique 2009 scientometric study of 25 million papers and 600 million citations that encapsulates the epistemology of modern science. The diffusive model predicts and explains, using no adjustable parameters, a surprisingly universal internal structure in the development of scientific research, which is essentially constant across the natural sciences, but which because of globalization changed qualitatively around 1960. Globalization corresponds physically to anomalous diffusion, which has been observed near the molecular glass transition, and can enhance molecular diffusion by factors as large as 100.

The considered method of learning the basics of microelectronic circuits and systems amplifier enables one to understand electrical processes deeper, to understand the relationship between static and dynamic characteristics and, finally, bring the learning process to the cognitive process. The scheme of problem-based learning can be represented by the following sequence of procedures: the contradiction is perceived and revealed; the cognitive motivation is provided by creating a problematic situation (the mental state of the student), moving the desire to solve the problem, to raise the question "why?", the hypothesis is made; searches for solutions are implemented; the answer is looked for. Due to the complexity of architectural schemes in the work the modern methods of computer analysis and synthesis are considered in the work.

Families made by science. Arnold Gesell and the technologies of modern child adoption.

PubMed

Herman, E

2001-12-01

This essay considers the effort to transform child adoption into a modern scientific enterprise during the first half of the twentieth century via a case study of Arnold Gesell (1880-1961), a Yale developmentalist well known for his studies of child growth and the applied technologies that emerged from them: normative scales promising to measure and predict development. Scientific adoption was a central aspiration for many human scientists, helping professionals, and state regulators. They aimed to reduce the numerous hazards presumed to be inherent in adopting children, especially infants, who were not one's "own." By importing insights and techniques drawn from the world of science into the practical world of family formation, scientific adoption stood for kinship by design. This case study explores one point of intersection between the history of science and the history of social welfare and social policy, simultaneously illustrating the cultural progress and power of scientific authority and the numerous obstacles to its practical realization.

Depression and creativity - the case of the German poet, scientist and statesman J. W. v. Goethe.

PubMed

Holm-Hadulla, Rainer M; Roussel, Martin; Hofmann, Frank-Hagen

2010-12-01

Goethe was one of the most creative poets, scientists and statesmen ever existing. Since the age of fourteen, he suffered from severe mood swings. His descriptions of feelings, emotions, and mental states related to temperamental and poetic melancholy, depressive episodes, dysthymic phases, and creativity are unique in respect to their phenomenological precision and richness. Furthermore, his (self-) therapeutic strategies and his self transformation in literature remain interesting until today for psychopathology, psychotherapy and creativity research. Goethe's self-assessments in his works and letters as well as the description of him by others are analysed by phenomenological and hermeneutic methods from the perspective of current psychiatric classification and psychotherapeutic knowledge. From a modern scientific perspective Goethe's mood swings are not to be regarded as expressions of a "poet's melancholy" in fashion at his time but as symptoms of depressive episodes. Several distinctive depressive episodes can be diagnosed which were characterized by long lasting depressive mood, lack of drive, interests and self-esteem combined with social retreat and physical illness. Moreover, Goethe described a mood disorder which fits into the modern concept of "driven dysthymia" or Bipolar II disorder. Goethe's depressive moods were associated with eminent poetic creativity whereas in times of scientific and political productivity Goethe seemed to be protected against depressive episodes. Phenomenological and hermeneutic analysis cannot offer causal explanations but only reasons for understanding and communicative action. In Goethe's life poetic incubation, illumination and elaboration seemed to be associated with psychic labilisation and dysthymia, sometimes with depressive episodes in a clinical sense. Thus, creative work was on the one hand triggered by depressive and dysthymic moods and served on the other hand to cope with depressive moods as well as with suicidal tendencies. In line with modern empirical results Goethe's scientific and social activities and achievements were associated with personal well-being, but also with lack of poetic inspiration.

In the fourth century A.H. (tenth century AD) many thinkers, philosophers, jurisprudents, poets, and authors were present in different scientific, literary and health fields in ancient Iran and Islamic world that by their hard attempts the sciences and literature were safe from incidents and resulted in growth, development and innovation of Islamic sciences. Meanwhile, Avicenna was superior to all others and the most famous scientist. He was a great human that by attempting hard, perseverance, stability, patience, and believing in God could complete supreme scientific ranks and compiled encyclopedia of Canon of Medicine and besides gathering many written important issues that most of them were confiscated at libraries of kings. He added medical experiences of ancient Iran and especially Jondishapour University and also his personal experiences and finally Canon of Medicine by benefiting from monotheistic style and science based on faith was written. He has written a book that is regarded as root and basics of modern medicine and by completing it some infrastructure health viewpoints and common medicine were created. It is a kind of book that in spite of scientific advances and production of modern research tools many of its contents are replaced with modern methods of medicine and health, but still many of its health basic messages, research orientation and monotheism with great dynamic mode is considerable at world's medical references. The aim of this study is evaluate the political situation of Avicenna's time and a review of his Godly writings. This is a library study by using electronic version of Canon of Medicine and other related resources. Findings, include writing style of monotheistic literature, and freeing from nihilism and affiliating diseases to Satan, jinn and such issues. It is necessary that our students within course of Iranian and Islamic culture and civilization to be more familiar with monotheistic thoughts and activities of scientists like Avicenna.

Generic and scientific constraints involving geoethics and geoeducation in planetary geosciences

NASA Astrophysics Data System (ADS)

Martínez-Frías, Jesús

2013-04-01

Geoscience education is a key factor in the academic, scientific and professional progress of any modern society. Geoethics is an interdisciplinary field, which involves Earth and Planetary Sciences as well as applied ethics, regarding the study of the abiotic world. These coss-cutting interactions linking scientific, societal and cultural aspects, consider our planet, in its modern approach, as a system and as a model. This new perspective is extremely important in the context of geoducation in planetary geosciences. In addition, Earth, our home planet, is the only planet in our solar system known to harbor life. This also makes it crucial to develop any scientific strategy and methodological technique (e.g. Raman spectroscopy) of searching for extraterrestrial life. In this context, it has been recently proposed [1-3] that the incorporation of the geoethical and geodiversity issues in planetary geology and astrobiology studies would enrich their methodological and conceptual character (mainly but not only in relation to planetary protection). Modern geoscience education must take into account that, in order to understand the origin and evolution of our planet, we need to be aware that the Earth is open to space, and that the study of meteorites, asteroids, the Moon and Mars is also essential for this purpose (Earth analogs are also unique sites to define planetary guidelines). Generic and scientific constraints involving geoethics and geoeducation should be incorporated into the teaching of all fundamental knowledge and skills for students and teachers.

Scientific Teaching: Defining a Taxonomy of Observable Practices

Couch, Brian A.; Brown, Tanya L.; Schelpat, Tyler J.; Graham, Mark J.; Knight, Jennifer K.

2015-01-01

Over the past several decades, numerous reports have been published advocating for changes to undergraduate science education. These national calls inspired the formation of the National Academies Summer Institutes on Undergraduate Education in Biology (SI), a group of regional workshops to help faculty members learn and implement interactive teaching methods. The SI curriculum promotes a pedagogical framework called Scientific Teaching (ST), which aims to bring the vitality of modern research into the classroom by engaging students in the scientific discovery process and using student data to inform the ongoing development of teaching methods. With the spread of ST, the need emerges to systematically define its components in order to establish a common description for education researchers and practitioners. We describe the development of a taxonomy detailing ST’s core elements and provide data from classroom observations and faculty surveys in support of its applicability within undergraduate science courses. The final taxonomy consists of 15 pedagogical goals and 37 supporting practices, specifying observable behaviors, artifacts, and features associated with ST. This taxonomy will support future educational efforts by providing a framework for researchers studying the processes and outcomes of ST-based course transformations as well as a concise guide for faculty members developing classes.

The Confluence of Perceiving and Thinking in Consciousness Phenomenology

PubMed Central

Wagemann, Johannes

2018-01-01

The processual relation of thinking and perceiving shall be examined from a historical perspective as well as on the basis of methodically conducted first-person observation. Historically, these two psychological aspects of human knowledge and corresponding philosophical positions have predominant alternating phases. At certain historical points, thinking and perceiving tend to converge, while in the interim phases they seem to diverge with an emphasis on one of them. While at the birth of modern science, for instance, these two forms of mental life were deeply interlinked, today they seem to be separated more than ever before – as a number of scientific crises have shown. Turning from the outer to the inner aspect of this issue, a phenomenological view becomes relevant. In terms of the consciousness phenomenology developed by Steiner (1861–1925) and Witzenmann’s (1905–1988) Structure Phenomenology, this article will show how a methodical integration of thinking and perceiving can be carried out on the basis of first-person observation. In the course of a skilled introspective or meditative self-observation the individual’s own mental micro-actions of separating and integrating come into view, jointly constituting what we usually call thinking and perceiving. Consequently, this approach includes a conceptual as well as a perceptual dimension the experimental confluence of which ties in with the methodological core principle of modern natural science. At the same time, making this principle explicit may open the way to a further development of human consciousness and its scientific delineation. PMID:29375432

How a modified approach to dental coding can benefit personal and professional development with improved clinical outcomes.

PubMed

Lam, Raymond; Kruger, Estie; Tennant, Marc

2014-12-01

One disadvantage of the remarkable achievements in dentistry is that treatment options have never been more varied or confusing. This has made the concept of Evidenced Based Dentistry more applicable to modern dental practice. Despite merit in the concept whereby clinical decisions are guided by scientific evidence, there are problems with establishing a scientific base. This is no more challenging than in modern dentistry where the gap between rapidly developing products/procedures and its evidence base are widening. Furthermore, the burden of oral disease continues to remain high at the population level. These problems have prompted new approaches to enhancing research. The aim of this paper is to outline how a modified approach to dental coding may benefit clinical and population level research. Using publically assessable data obtained from the Australian Chronic Disease Dental Scheme and item codes contained within the Australian Schedule of Dental Services and Glossary, a suggested approach to dental informatics is illustrated. A selection of item codes have been selected and expanded with the addition of suffixes. These suffixes provided circumstantial information that will assist in assessing clinical outcomes such as success rates and prognosis. The use of item codes in administering the CDDS yielded a large database of item codes. These codes are amenable to dental informatics which has been shown to enhance research at both the clinical and population level. This is a cost effective method to supplement existing research methods. Copyright © 2014 Elsevier Inc. All rights reserved.

Geoethics and natural hazards: general reflections on the relationship between geoscientists and society

NASA Astrophysics Data System (ADS)

Peppoloni, Silvia

2013-04-01

The development of modern science has changed the relationship between humans and natural phenomena. The great geoscientists of the past have contributed to the construction of the modern world, by revolutionizing the way in which humans perceive themselves, by changing their references of space and time inside the Universe. However, in the majority of the populations is observed the persistence of a fatalistic mentality or an attitude which believes that science can solve everything. In fact, throughout the centuries the fear of earthquakes, eruptions, floods has not changed in humans. The scientific rational approach is certainly an effective way to limit the scope of irrationality and uncertainty. The fear is not eliminable, but the proper dissemination of scientific knowledge and an adequate preparedness can help to mitigate it and transform it into an attitude of respect for the natural processes that govern the Geosphere. Therefore, geoscientists have a great responsibility towards society, which needs to face natural hazards. They have the duty to transfer knowledge and methods, to communicate information and errors, to awaken in people the interest for the phenomena and their evolution. Ultimately, geoscientists can contribute to bring science closer to society. The lack of involvement in scientific knowledge of the various components of society (citizens, politicians, mass media) can lead to two negative consequences: • the cultural and social marginalization of scientists, together with a loss of the sense of the role they can play in protecting society from natural hazards; • the tendency of people to embrace preconceived ideas in non critical way, ideas provided by a media information often incorrect, to lose good sense, until to develop fideistic attitudes based on few observed elements. In the scientific field the probabilistic method is a widespread way to analyze the natural phenomena. It allows to give an estimate of time, place and size of an event, in an attempt to manage the natural hazards that threaten human life and activities. However, geoscientists have to be aware of the risk that the uncertainty of occurrence of a natural phenomenon becomes an alibi to decline their responsibilities. The population should be informed also about the limits of the scientific methods used, so that it can better understand and share the decisions taken to deal with a natural hazard. Informing the population on natural risks should be prioritized for geoscientists, their ethical commitment to reduce as much as possible the sufferings of human beings and to manage the environment in a reasonable and responsible way.

The International Year of Astronomy 2009 was conceived to honor the 400th anniversary of Galileo's first telescopic observations in 1609. Galileo gave priority to evidence over popular belief. This completely changed the existing world view and formed the basis for the modern scientific process. Galileo's work provides an example of how science is grounded in evidence rather than belief or opinion. The goal of this project is to present K-16 instructors with an alternative to the traditional scientific method unit. We will briefly describe two activities that model Galileo's telescopic observations of Jupiter and Venus and simultaneously build abilities and understandings of scientific inquiry. Participants will learn about activities where students record and analyze data, make predictions, use multiple forms of evidence, and use a variety of models to find support for a heliocentric solar system. Materials will be available for download for those interested in using this in their classroom as well as for the purpose of training other teachers.

Trajectory Optimization for Missions to Small Bodies with a Focus on Scientific Merit.

PubMed

Englander, Jacob A; Vavrina, Matthew A; Lim, Lucy F; McFadden, Lucy A; Rhoden, Alyssa R; Noll, Keith S

2017-01-01

Trajectory design for missions to small bodies is tightly coupled both with the selection of targets for a mission and with the choice of spacecraft power, propulsion, and other hardware. Traditional methods of trajectory optimization have focused on finding the optimal trajectory for an a priori selection of destinations and spacecraft parameters. Recent research has expanded the field of trajectory optimization to multidisciplinary systems optimization that includes spacecraft parameters. The logical next step is to extend the optimization process to include target selection based not only on engineering figures of merit but also scientific value. This paper presents a new technique to solve the multidisciplinary mission optimization problem for small-bodies missions, including classical trajectory design, the choice of spacecraft power and propulsion systems, and also the scientific value of the targets. This technique, when combined with modern parallel computers, enables a holistic view of the small body mission design process that previously required iteration among several different design processes.

The End of the Rainbow? Color Schemes for Improved Data Graphics

NASA Astrophysics Data System (ADS)

Light, Adam; Bartlein, Patrick J.

2004-10-01

Modern computer displays and printers enable the widespread use of color in scientific communication, but the expertise for designing effective graphics has not kept pace with the technology for producing them. Historically, even the most prestigious publications have tolerated high defect rates in figures and illustrations, and technological advances that make creating and reproducing graphics easier do not appear to have decreased the frequency of errors. Flawed graphics consequently beget more flawed graphics as authors emulate published examples. Color has the potential to enhance communication, but design mistakes can result in color figures that are less effective than gray scale displays of the same data. Empirical research on human subjects can build a fundamental understanding of visual perception and scientific methods can be used to evaluate existing designs, but creating effective data graphics is a design task and not fundamentally a scientific pursuit. Like writing well, creating good data graphics requires a combination of formal knowledge and artistic sensibility tempered by experience: a combination of ``substance, statistics, and design''.

A Proposal for a Research-based Constructivist Physics-and-Pedagogy Course

NASA Astrophysics Data System (ADS)

Zirbel, Esther

2006-12-01

This poster proposes a research-based science-and-pedagogy course that will combine the learning of fundamental physics concepts with methods of how to teach these concepts. Entitled “Understanding the Cosmos: From Antiquity to the Modern Day,” the course will explore how people learn science concepts through the ages, and from childhood through adulthood. This course will use the historical-constructivist approach to illustrate how our understanding of scientific phenomena advanced as we progressed from simple 2-dimensional thinking (starting with the flat Earth concept) to 3-D thinking (learning about the structure of the solar system) to 4-D thinking (understanding space-time and theories about the Big Bang). While transitioning from Impetus to Aristotelian to Newtonian to Einsteinian thinking, students will learn the essence of scientific thinking and inquiry. The overall goal of this course is to excite students in the process of scientific discovery, help them develop scientific reasoning skills, and provide them with fulfilling experiences of truly understanding science concepts. This will be done by employing active engagement techniques (e.g., peer tutoring, Socratic dialogue, and think/pair/share methods) and by challenging students to articulate their thoughts clearly and persuasively. This course could be of value for anybody wanting to enter the teaching profession or simply for anybody who would like to deepen their science understanding.

Science communication as political communication

2014-01-01

Scientific debates in modern societies often blur the lines between the science that is being debated and the political, moral, and legal implications that come with its societal applications. This manuscript traces the origins of this phenomenon to professional norms within the scientific discipline and to the nature and complexities of modern science and offers an expanded model of science communication that takes into account the political contexts in which science communication takes place. In a second step, it explores what we know from empirical work in political communication, public opinion research, and communication research about the dynamics that determine how issues are debated and attitudes are formed in political environments. Finally, it discusses how and why it will be increasingly important for science communicators to draw from these different literatures to ensure that the voice of the scientific community is heard in the broader societal debates surrounding science.

Knowledge in motion: The cultural politics of modern science translations in Arabic.

PubMed

Elshakry, Marwa S

2008-12-01

This essay looks at the problem of the global circulation of modem scientific knowledge by looking at science translations in modern Arabic. In the commercial centers of the late Ottoman Empire, emerging transnational networks lay behind the development of new communities of knowledge, many of which sought to break with old linguistic and literary norms to redefine the basis of their authority. Far from acting as neutral purveyors of "universal truths," scientific translations thus served as key instruments in this ongoing process of sociopolitical and epistemological transformation and mediation. Fierce debates over translators' linguistic strategies and choices involved deliberations over the character of language and the nature of "science" itself. They were also crucially shaped by such geopolitical factors as the rise of European imperialism and anticolonial nationalism in the region. The essay concludes by arguing for the need for greater attention to the local factors involved in the translation of scientific concepts across borders.

The problem of plagiarism represents one of the burning issues of the modern scientific world. Detection of plagiarism is a problem that the Editorial Board encounters in their daily work. Software solutions represent a good solution for the detection of plagiarism. The problem of plagiarism will become most discussed topic of the modern scientific world, especially due to the development of standard measures, which rank the work of one author. Investment in education, education of young research personnel about the importance of scientific research, with paying particular attention on ethical behavior, becomes an imperative of academic staff. Editors have to invest additional effort in the development of the base of reviewers team as well as in their proper guidance, because after all, despite the software solutions, they are the best weapon to fight plagiarism. Peer review process should be a key of successful operation of each journal.

Anthropological film: a scientific and humanistic resource.

PubMed

Soren, E R

1974-12-20

More than a scientific endeavor but not strictly one of the humanities either, anthropology stands between these basic kinds of intellectual pursuit, bridging and contributing to both. Not limited to natural history, anthropology touches art, historical process, and human values, drawing from the materials and approaches of both science and humanities. This professional interest in a broad understanding of the human condition has led anthropologists to adapt and use modern cameras and films to inquire further into the variety of ways of life of mankind and to develop method and theory to prepare anthropological film as a permanent scientific and humanistic resource. Until quite recently the evolution of human culture and organization has diverged in the hitherto isolated regions of the world. Now this divergence has virtually ceased; we are witnessing an unprecedented period in human history-one where cultural divergence has turned to cultural convergence and where the varieties of independently evolved expressions of basic human potential are giving way to a single system of modern communications, transport, commerce, and manufacturing technology. Before the varieties of ways of life of the world disappear, they can be preserved in facsimile in anthropological films. As primary, undifferentiated visual information, these films facilitate that early step in the creation of new knowledge which is sometimes called humanistic and without which scientific application lies dormant, lacking an idea to test. In keeping with the two scholarly faces of anthropology, humanistic and scientific, anthropological films may provide material permitting both humanistic insight and the more controlled formulations of science. The lightweight filming equipment recently developed has been adapted by anthropologists as a tool of scholarly visual inquiry; methods of retrieving visual data from changing and vanishing ways of life have been developed; and new ways to reveal human beings to one another by using such visual resources have been explored. As a result, not only can anthropological film records permit continued reexamination of the past human conditions from which the present was shaped, but they also facilitate an ongoing public and scientific review of the dynamics of the human behavioral and social repertoire in relation to the contemporary conditions which pattern human responses and adaptation. How man fits into and copes with the changing world is of vital interest and concern. Visual data provide otherwise unobtainable information on human potential, behavior, and social organization. Such information, fed into the public media, facilitates informed consideration of alternative possibilities. By contributing to a better informed society, such films will help make our future more human and more humane.

Evolution of computational chemistry, the "launch pad" to scientific computational models: The early days from a personal account, the present status from the TACC-2012 congress, and eventual future applications from the global simulation approach

Clementi, Enrico

2012-06-01

This is the introductory chapter to the AIP Proceedings volume "Theory and Applications of Computational Chemistry: The First Decade of the Second Millennium" where we discuss the evolution of "computational chemistry". Very early variational computational chemistry developments are reported in Sections 1 to 7, and 11, 12 by recalling some of the computational chemistry contributions by the author and his collaborators (from late 1950 to mid 1990); perturbation techniques are not considered in this already extended work. Present day's computational chemistry is partly considered in Sections 8 to 10 where more recent studies by the author and his collaborators are discussed, including the Hartree-Fock-Heitler-London method; a more general discussion on present day computational chemistry is presented in Section 14. The following chapters of this AIP volume provide a view of modern computational chemistry. Future computational chemistry developments can be extrapolated from the chapters of this AIP volume; further, in Sections 13 and 15 present an overall analysis on computational chemistry, obtained from the Global Simulation approach, by considering the evolution of scientific knowledge confronted with the opportunities offered by modern computers.

Design of Unstructured Adaptive (UA) NAS Parallel Benchmark Featuring Irregular, Dynamic Memory Accesses

Feng, Hui-Yu; VanderWijngaart, Rob; Biswas, Rupak; Biegel, Bryan (Technical Monitor)

2001-01-01

We describe the design of a new method for the measurement of the performance of modern computer systems when solving scientific problems featuring irregular, dynamic memory accesses. The method involves the solution of a stylized heat transfer problem on an unstructured, adaptive grid. A Spectral Element Method (SEM) with an adaptive, nonconforming mesh is selected to discretize the transport equation. The relatively high order of the SEM lowers the fraction of wall clock time spent on inter-processor communication, which eases the load balancing task and allows us to concentrate on the memory accesses. The benchmark is designed to be three-dimensional. Parallelization and load balance issues of a reference implementation will be described in detail in future reports.

Bayesian learning

In 1983 and 1984, the Infrared Astronomical Satellite (IRAS) detected 5,425 stellar objects and measured their infrared spectra. In 1987 a program called AUTOCLASS used Bayesian inference methods to discover the classes present in these data and determine the most probable class of each object, revealing unknown phenomena in astronomy. AUTOCLASS has rekindled the old debate on the suitability of Bayesian methods, which are computationally intensive, interpret probabilities as plausibility measures rather than frequencies, and appear to depend on a subjective assessment of the probability of a hypothesis before the data were collected. Modern statistical methods have, however, recently been shown to also depend on subjective elements. These debates bring into question the whole tradition of scientific objectivity and offer scientists a new way to take responsibility for their findings and conclusions.

The Influence of Positivism in the Nineteenth Century Astronomy in Argentina

NASA Astrophysics Data System (ADS)

Santilli, Haydée; Cornejo, Jorge Norberto

2013-06-01

In this paper we analyze the influence of positivism in Argentina astronomical culture in the nineteenth century. We did the analysis from two dimensions, scientific knowledge development and science teaching. Because Argentina was a very young country at that time, it was of singular importance, not only the development of scientific knowledge itself, but also the training of human resources for the transfer of such knowledge. In this regard, the influence of astronomy, in its role of modernizing discipline related to positivist ideal, was particularly noticeable in the training of teachers of primary schools. Domingo F. Sarmiento represents a turning point for the astronomy development in Argentina; his thought was strongly influenced by the Comtean positivism. Sarmiento believed that Copernican astronomy was one of the critical scientific disciplines to the formation of a "modern" citizen. Astronomy in Argentina was influenced by two epistemological streams: French and German positivism; however the first one was the most important. We shall show the relevant influence of the socio-historical context over the scientific development. We shall also see that science was a fundamental social actor in Argentina history.

Onwards facing backwards: the rhetoric of science in nineteenth-century Greece.

PubMed

Tampakis, Kostas

2014-06-01

The aim of this paper is to show how the Greek men of science negotiated a role for their enterprise within the Greek public sphere, from the institution of the modern Greek state in the early 1830s to the first decades of the twentieth century. By focusing on instances where they appeared in public in their official capacity as scientific experts, I describe the rhetorical schemata and the narrative strategies with which Greek science experts engaged the discourses prevalent in nineteenth- and early twentieth-century Greece. In the end, my goal is to show how they were neither zealots of modernization nor neutral actors struggling in isolated wastelands. Rather, they appear as energetic agents who used scientific expertise, national ideals and their privileged cultural positions to construct a rhetoric that would further all three. They engaged eagerly and consistently with emerging political views, scientific subjects and cultural and political events, without presenting themselves, or being seen, as doing anything qualitatively different from their peers abroad. Greek scientists cross-contextualized the scientific enterprise, situating it in the space in which they were active.

This article is concerned with the modern concepts of chronic obstructive pulmonary disease. Also, it presents the international definition of "pulmonary rehabilitation". Especially much attention is given to the physical rehabilitation as one of the main and fundamental components of medical rehabilitation of the patients presenting with chronic obstructive pulmonary disease. The up-to-date approaches to the application of fitness gymnastics for the purpose of scientific research and clinical practice are considered with special reference to the combination of cyclic, static, and dynamic loads with the use of relevant modern equipment. The data on the effectiveness and safety of these rehabilitative technologies are discussed in the context of their application for further research in the field of rehabilitative medicine. Recommendations are proposed on the implementation of these methods in the current practical work.

This paper describes a project to establish and evaluate online study partnerships, using social networking applications, between final year Canadian nursing students at the University of British Columbia (UBC) and second year undergraduate science education students at the University of Plymouth (UoP) in the UK. The project took place between 2009 and 2010 and evaluated the use of social networking applications with international interdisciplinary partnerships between Canadian and UK students. A multi-method evaluation strategy incorporating questionnaires, online focus groups and web analytics was used to explore the value of social media to promote the exchange of ideas and discussion of scientific philosophy in different contexts, between students working in disciplines with differing philosophical perspectives principally modern/post-modern, quantitative/qualitative, empirical/theoretical. This project resulted in a very successful collaborative partnership between UK and Canadian students. Copyright © 2012 Elsevier Ltd. All rights reserved.

Evolution and convergence of the patterns of international scientific collaboration.

PubMed

Coccia, Mario; Wang, Lili

2016-02-23

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

The secondary development of major traditional Chinese medicine varieties is one of important links during the modernization, scientification and standardization of traditional Chinese medicines. How to accurately and effectively identify the pharmacodynamic material basis of original formulae becomes the primary problem in the secondary development, as well as the bottleneck in the modernization development of traditional Chinese medicines. On the basis of the existing experimental methods, and according to the study thought that the multi-component and complex effects of traditional Chinese medicine components need to combine multi-disciplinary methods and technologies, we propose the study thought of the material basis of secondary development of major traditional Chinese medicine varieties based on the combination of in vivo and in vitro experiments. It is believed that studies on material basis needs three links, namely identification, screening and verification, and in vivo and in vitro study method corresponding to each link is mutually complemented and verified. Finally, the accurate and reliable material basis is selected. This thought provides reference for the secondary development of major traditional Chinese medicine varieties and studies on compound material basis.

Verification of watershed vegetation restoration policies, arid China

Verification of restoration policies that have been implemented is of significance to simultaneously reduce global environmental risks while also meeting economic development goals. This paper proposed a novel method according to the idea of multiple time scales to verify ecological restoration policies in the Shiyang River drainage basin, arid China. We integrated modern pollen transport characteristics of the entire basin and pollen records from 8 Holocene sedimentary sections, and quantitatively reconstructed the millennial-scale changes of watershed vegetation zones by defining a new pollen-precipitation index. Meanwhile, Empirical Orthogonal Function method was used to quantitatively analyze spatial and temporal variations of Normalized Difference Vegetation Index in summer (June to August) of 2000–2014. By contrasting the vegetation changes that mainly controlled by millennial-scale natural ecological evolution with that under conditions of modern ecological restoration measures, we found that vegetation changes of the entire Shiyang River drainage basin are synchronous in both two time scales, and the current ecological restoration policies met the requirements of long-term restoration objectives and showed promising early results on ecological environmental restoration. Our findings present an innovative method to verify river ecological restoration policies, and also provide the scientific basis to propose future emphasizes of ecological restoration strategies.

A primary goal of many undergraduate- and graduate-level courses in the physical sciences is to prepare students to engage in scientific research or to prepare students for careers that leverage skillsets similar to those used by research scientists. Even for students who may not intend to pursue a career with these characteristics, exposure to the context of applications in modern research can be a valuable tool for teaching and learning. However, a persistent barrier to student participation in research is familiarity with the technical language, format, and context that academic researchers use to communicate research methods and findings with each other: the literature of the field. Astrobites, an online web resource authored by graduate students, has published brief and accessible summaries of more than 1300 articles from the astrophysical literature since its founding in 2010. This article presents three methods for introducing students at all levels within the formal higher education setting to approaches and results from modern research. For each method, we provide a sample lesson plan that integrates content and principles from Astrobites, including step-by-step instructions for instructors, suggestions for adapting the lesson to different class levels across the undergraduate and graduate spectrum, sample student handouts, and a grading rubric.

A special role in the history of the Kazan University was played by the great mathematician Nikolai Lobachevsky - the founder of non-Euclidean geometry (1826). Historically, the thousand-year old city of Kazan and the two-hundred-year old Kazan University carry out the role of the scientific, organizational, and cultural educational center of the Volga region. For the continued successful development of educational and scientific-educational activity of the Russian Federation, the Republic Tatarstan, Kazan was offered the national project: the International Center of the Sciences and Internet Technologies "GeoNa" (Geometry of Nature - GeoNa - is wisdom, enthusiasm, pride, grandeur). This is a modern complex of conference halls including the Center for Internet Technologies, a 3D Planetarium - development of the Moon, PhysicsLand, an active museum of natural sciences, an oceanarium, and a training complex "Spheres of Knowledge". Center GeoNa promotes the direct and effective channel of cooperation with scientific centers around the world. GeoNa will host conferences, congresses, fundamental scientific research sessions of the Moon and planets, and scientific-educational actions: presentation of the international scientific programs on lunar research and modern lunar databases. A more intense program of exchange between scientific centers and organizations for a better knowledge and planning of their astronomical curricula and the introduction of the teaching of astronomy are proposed. Center GeoNa will enable scientists and teachers of the Russian universities with advanced achievements in science and information technologies to join together to establish scientific communications with foreign colleagues in the sphere of the high technology and educational projects with world scientific centers.

Study on pharmacodynamic material basis of traditional Chinese medicines is one of the key issues for the modernization of traditional Chinese medicine. Having introduced the monoclonal antibody technology into the study on pharmacodynamic material basis of traditional Chinese medicines, the author prepared the immunoaffinity chromatography column by using monoclonal antibodies in active components of traditional Chinese medicines, so as to selectively knock out the component from herbs or traditional Chinese medicine compounds, while preserving all of the other components and keeping their amount and ratio unchanged. A comparative study on pharmacokinetics and pharmacodynamics was made to explicitly reveal the correlation between the component and the main purpose of traditional Chinese medicines and compounds. The analysis on pharmacodynamic material basis of traditional Chinese medicines by using specific knockout technology with monoclonal antibodies is a new method for study pharmacodynamic material basis in line with the characteristics of traditional Chinese medicines. Its results can not only help study material basis from a new perspective, but also help find the modern scientific significance in single herb or among compounds of traditional Chinese medicines.

Effect of regional slopes on local structure and exploration of tilted paleo-highs

Nazarov, D.A.; Chernobrov, B.S.

1986-06-01

Prospects for discovering local highs in old petroleum-producing regions have by now been substantially exhausted. Hence it is of great importance at this stage to seek non-anticlinal accumulations of hydrocarbons, including those in traps genetically associated with tilted paleo-highs, often represented in the modern structural plan by structural noses and terraces. Appropriate exploration for such types of deposits may soon become important in Ciscaucasia and other old petroleum-producing regions. Consequently, problems of the scientific basis for prospecting paleo-highs tilted in the modern structural plan, and developing procedures both for revealing and also for assessing their expression in the structural planmore » during different stages of geological history, and establishing the time and depth of changes in aspect, will become extremely topical. In order to discover possible local highs and to study their features within the margins of the platformal basins and the platformal edges of the marginal troughs, the authors use the method of removing the effect of the regional slope on the local structural plan. This paper describes this method. 13 references.« less

They require a dedicated and innovative organization able to satisfy contemporarily various technical and logistic constraints imposed by the final user, and guarantee the satisfaction of technical specifications, identified on the basis of scientific aims. In order to satisfy all the above, the management has to be strategically innovative and intuitive, by removing, first of all, the bottlenecks that are pointed out, usually only at the end of the projects, as the causes of general dissatisfaction. More than 30 years spent working on complex multidisciplinary systems and 20 years of formative experience in managing contemporarily both scientific, technological and industrial projects have given the author the possibility to study, test and validate strategies for parallel project management and integrated design, merged in a sort of unique optimized task, using the newly-coined word "Technomethodology". The paper highlights useful information to be taken into consideration during project organization to minimize the program deviations from the expected goals and describe some of the basic meanings of this new advanced method that is the key for parallel successful management of multiple and interdisciplinary activities.

Is homeopathy a science?--Continuity and clash of concepts of science within holistic medicine.

PubMed

Schmidt, Josef M

2009-06-01

The question of whether homeopathy is a science is currently discussed almost exclusively against the background of the modern concept of natural science. This approach, however, fails to notice that homeopathy-in terms of history of science-rests on different roots that can essentially be traced back to two most influential traditions of science: on the one hand, principles and notions of Aristotelism which determined 2,000 years of Western history of science and, on the other hand, the modern concept of natural science that has been dominating the history of medicine for less than 200 years. While Aristotle's "science of the living" still included ontologic and teleologic dimensions for the sake of comprehending nature in a uniform way, the interest of modern natural science was reduced to functional and causal explanations of all phenomena for the purpose of commanding nature. In order to prevent further ecological catastrophes as well as to regain lost dimensions of our lives, the one-sidedness and theory-loadedness of our modern natural-scientific view of life should henceforth be counterbalanced by lifeworld-practical Aristotelic categories. In this way, the ground would be ready to conceive the scientific character of homeopathy-in a broader, Aristotelian sense.

Fundamentals--Rudolf Virchow and modern medicine.

The 19th century pathologist Rudolf Virchow was a physician, scientist, and revolutionary. The preeminent medical investigator of his day, Virchow remains best-known for his theory of cellular pathology, which laid the conceptual foundation for modern scientific medicine. Less appreciated are Virchow's numerous accomplishments in public health, anthropology, and European politics, including his quest for social justice and democracy in Imperial Germany. The study of Virchow's life and writings may provide contemporary physicians with a powerful role model as we grapple with the complexities of the modern medical enterprise. PMID:9735691

Integration of educational and scientific-technological areas during the process of education of aerospace engineers

National priorities, defined by modern state of high-tech industries, demand adequate problem solving of training professionals possessing required modern qualifications. Modern tendencies of the development of aerospace technologies, harsh competition in the market of space services and expansion of international cooperation for implementation of space projects, demand sharp increase of the scientific/technical level and competitiveness of the developed projects. Especially important is to be able to solve technological problems, which in turn define the cost and quality attributes of the designed item, as well as the ability to utilize the most modern design principles. Training of highly efficient, creative professionals who are capable of generating and implementing new ideas is a very important factor driving not only the development of national economy and industry, but also enriching the human capital of the country. Moscow State Technical University named after N.E. Bauman developed and successfully implemented the project-oriented technology of professional training for aerospace industry. It assumes a multitude of forms, methodologies and organizational events, which allow preparing the specialists - on the basis of integration of scientific/technological and educational environment - who are adapted to the conditions of the intellectual market. The Youth Space Center of the University is the base where graduate and post-graduate students attend unique lectures as a part of the facultative course "Applied Cosmonautics", participate in annual International Youth Science School "Space Development: Theory and Practice" and develop innovative technical projects aimed at creation of real-life space hardware. Microsatellite technologies are being developed in Bauman University through various projects, which are implemented in a coordinated manner by way of accomplishing the following steps: development of small-size satellites by universities, using them as test-beds for quick and affordable trial-and-test of new technologies and design solutions in aerospace followed by implementation of selected efficiencies in the industry; development and improvement of ground control infrastructure based in the university, which includes the Mission Control Center and the Earth Remote Sensing Center; development of cooperative partnerships with international partners in the field of microsatellite technologies with the goal of sharing experience, uniting efforts in preparing and running scientific and educational experiments and creating next-generation spacecraft by multi-national student groups. Such approaches allow creating seamless environment that unites educational, scientific and innovative processes. This allows students to develop high professionalism, modern engineering thinking and stable engineering skills at an early stage of education at the university.

Although science is not a key issue for the general public in The Netherlands, and scouting talents is not a customary activity, it is of the utmost importance for the scientific progress to detect gifted young people and to motivate them for a career in medical sciences. The scouting of talent should start as early as possible. A working group of the Royal Netherlands Academy of Arts and Sciences has issued a report on secondary schooling in which scouting of talent is a central issue. The modern medical curricula at the universities in The Netherlands all offer a substantial elective programme and the modern teaching in small groups also offers opportunities for teachers to detect talent. Recognition of scientific talent is further possible during the research period that every medical student has to go through. In Nijmegen, the Department of Internal Medicine organises a yearly master class at the end of the summer for the best second year medical students; in this course they are introduced to the scientific approach in medicine: from bedside to bench and vice versa. With this course we try to enforce the motivation for medical research. A prime instrument for the development of scientific talent is the nationally funded PhD track for medical specialists in training.

Report of the Federation of European Laboratory Animal Science Associations Working Group on animal identification.

2013-01-01

The primary aim of this report is to assist scientists in selecting more reliable/suitable identification (ID) methods for their studies. This is especially true for genetically altered (GA) animals where individual identification is strictly necessary to link samples, research design and genotype. The aim of this Federation of European Laboratory Animal Science Associations working group was to provide an update of the methods used to identify rodents in different situations and to assess their implications for animal welfare. ID procedures are an indispensable prerequisite for conducting good science but the degree of invasiveness differs between the different methods; therefore, one needs to make a good ethical evaluation of the method chosen. Based on the scientific literature the advantages and disadvantages of various methods have been presented comprehensively and this report is intended as a practical guide for researchers. New upcoming methods have been included next to the traditional techniques. Ideally, an ID method should provide reliable identification, be technically easy to apply and not inflict adverse effects on animals while taking into account the type of research. There is no gold standard method because each situation is unique; however, more studies are needed to better evaluate ID systems and the desirable introduction of new and modern approaches will need to be assessed by detailed scientific evaluation.

[A study of development of medicine and science in the nineteenth century science fiction: biomedical experiments in Mary Shelley's Frankenstein].

Choo, Jae-Uk

2014-12-01

As the sciences advanced rapidly in the modern European world, outstanding achievements have been made in medicine, chemistry, biology, physiology, physics and others, which have been co-influencing each of the scientific disciplines. Accordingly, such medical and scientific phenomena began to be reflected in novels. In particular, Mary Shelley's Frankenstein includes the diverse aspects of the change and development in the medicine and science. Associated with medical and scientific information reflected in Frankenstein and Frankenstein's experiments in the text, accordingly, this research will investigate the aspects of medical and scientific development taking place in the nineteenth century in three ways. First, the medical and scientific development of the nineteenth century has been reviewed by summerizing both the information of alchemy in which Frankenstein shows his interest and the new science in general that M. Waldman introduces in the text. Second, the actual features of medical and scientific development have been examined through some examples of the experimental methods that M. Waldman implicitly uttered to Frankenstein. Third, it has been checked how the medical and scientific development is related to the main issues of mechanism and vitalism which can be explained as principles of life. Even though this research deals with the developmental process of medicine & science and origin & principles of life implied in Mary Shelley's Frankenstein, its significance is that it is the interdisciplinary research focussing on how deeply medical and scientific discourse of Mary Shelley's period has been imbedded in the nineteenth century novel.

Risk communication and human biomonitoring: which practical lessons from the Belgian experience are of use for the EU perspective?

PubMed Central

Keune, Hans; Morrens, Bert; Loots, Ilse

2008-01-01

Background In order to investigate and monitor environmental health in Flanders (the Dutch speaking part of Belgium), the Flemish government funded the Centre of Expertise for Environment and Health, which started a human biomonitoring campaign in 2001. In addition to environmental health experts measuring environmental pollutants and health effects in human beings, social scientific experts at the Centre focus on risk communication associated with the human biomonitoring campaign. Methods In the literature about risk communication an evolution can be traced from traditional, one-way communication, restricted to the dissemination of information from experts to the public, to more modern, two-way risk communication, with a focus on participation and cooperation between scientists, policy-makers and the public. Within the Centre of Expertise for Environment and Health this discourse was first translated into some general principles and guidelines for external communication, at a 'Ten Commandments level'. These principles needed to be incorporated in the day-to-day practice of human biomonitoring research. Results The social scientific experts at the Centre developed a combined risk communication strategy. On the one hand the strategy consists of traditional risk communication for external communication purposes, for example information meetings and digital newsletters. On the other hand it consists of a step by step approach of incorporating more modern risk communication, for example a risk perception questionnaire, dialogical experiments for involving local stakeholders, and an action-plan for interpreting results for policy making. Conclusion With a parallel strategy of traditional and modern communication, of external and internal reflection, and through different social scientific projects, the Flemish Centre of Expertise of Environment and Health incorporates risk communication in the day-to-day practice of human biomonitoring research. A direct and continuous involvement of the social scientist, an openness between all colleagues involved, and the awareness of a fine balance between quality and practicability are important success factors. These lessons may be helpful and inspirational for a European human biomonitoring project. PMID:18541065

Traditional Chinese medicine (TCM) prescription is the main therapies for disease prevention and treatment in Chinese medicine. Following the guidance of the theory of TCM and developing drug by composing prescriptions of TCM materials and pieces, it is a traditional application mode of TCM, and still widely used in clinic. TCM prescription has theoretical advantages and rich clinical application experience in dealing with multi-factor complex diseases, but scientific research is relatively weak. The lack of scientific cognition of the effective substances and mechanism of Chinese medicine leads to insufficient understanding of the efficacy regularity, which affects the stability of effect and hinders the improvement of quality of Chinese medicinal products. Component-based Chinese medicine (CCM) is an innovation based on inheritance, which breaks through the tradition of experience-based prescription and realize the transformation of compatibility from herbal pieces to components. CCM is an important achievement during the research process of modernization of Chinese medicine. Under the support of three national "973" projects, in order to reveal the scientific connotation of the prescription compatibility theory and develop innovative Chinese drugs, we have launched theoretical innovation and technological innovation around the "two relatively clear", and opened up the research field of CCM. CCM is an innovation based on inheritance, breaking through the tradition of experience based prescription, and realizing the transformation from compatibility of herbal pieces to component compatibility, which is an important achievement of the modernization of traditional Chinese medicine. In the past more than 10 years, with the deepening of research and the expansion of application, the theory and methods of CCM and efficacy-oriented compatibility have been continuously improved. The value of CCM is not only in developing new drug, more important is to build a communication bridge between traditional Chinese medicine and modern science and construct the system of key technologies which meet the need of innovation and development of TCM. This paper focused on the research progress, related concepts and technology development of CCM, as well as its application prospect in the theory research of Chinese medicine, development of innovative Chinese drugs, secondary development of Chinese patent medicine and upgrading of pharmaceutical technology.

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

The advent of genomics, proteomics, and microarray technology has brought much excitement to science, both in teaching and in learning. The public is eager to know about the processes of life. In the present context of the explosive growth of scientific information, a major challenge of modern cell biology is to popularize basic concepts of structures and functions of living cells, to introduce people to the scientific method, to stimulate inquiry, and to analyze and synthesize concepts and paradigms. In this essay we present our experience in mixing science and education in Brazil. For two decades we have developed activities for the science education of teachers and undergraduate students, using microscopy images generated by our work as cell biologists. We describe open-air outreach education activities, games, cell modeling, and other practical and innovative activities presented in public squares and favelas. Especially in developing countries, science education is important, since it may lead to an improvement in quality of life while advancing understanding of traditional scientific ideas. We show that teaching and research can be mutually beneficial rather than competing pursuits in advancing these goals. PMID:15257338

Bleeding and cupping have been used in medicine since ancient times in the treatment of fevers and local inflammatory disorders. Local bleeding, by 'wet cupping', was effected by a scarificator or by leeches. John Hunter recommended venesection in moderation but preferred leeches for local bleeding. Bleeding as an accepted therapeutic practice went out of vogue in the middle of the nineteenth century as a result of the introduction of modern scientific methods. Dry cupping and the use of leeches, as counter irritants, persisted until the middle of this century. Images Fig. 1 Fig. 2 Fig. 3 Fig. 4 Fig. 5 Fig. 6 PMID:6338802

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.

[Prof. Giuseppe Moscati (1880-1927). A special issue on his scientific production].

PubMed

Cascella, Marco

2016-08-01

Professor Giuseppe Moscati (1880-1927) was canonized by the Catholic Church in 1987. This act recognized the extraordinary qualities of a doctor who, considering his work as a "sublime mission", dedicated his life to helping the sick. The fame of the "Holy doctor" or "doctor of the poor", as people called him, was soon widespread and, immediately after his death, made him the subject of several biographies. These treatises, mainly written by religious hagiographers, have little analyzed Moscati as a doctor and scientist, or, in rare cases, privileged the description of his medical career, touching only marginally salient aspects of his work as a scientist and researcher. The purpose of this paper is to provide an insight into the figure of Moscati as a scientist, contextualizing his research activities in the scientific fields of biochemistry and physiology, which were flourishing in the early twentieth century. By a more careful analysis, his scientific production appears original for the resource-poor context and the innovative research method. The Italian scientist, combining physiological chemistry and biochemistry at the clinic, anticipated the birth of modern branches as the "Laboratory Medicine" and the "Clinical Pathology". In particular, he carried out studies on diabetes, storage diseases, metabolism, toxicology, pathology, nephrology and occupational diseases. Moreover, he anticipated the concept of modern laboratory in the oncological field as means for the characterization of the "nature" of neoplasms and related therapeutic approaches. Therefore, even if Moscati was rarely mentioned by the sources of the history of medicine, it is safe to assume that the fame of the Saint has paradoxically eclipsed that of the scientist, preventing him from receiving the necessary reward.

Rapid development of communication facilities leads growth of interactions done via electronic means. However we can see some paradox in this segment in last times: Extending of communication facilities increases collaboration chaos. And it is very sensitive for space missions in general and scientific space mission particularly because effective decision of this task provides successful realization of the missions and promises increasing the ratio of functional characteristic and cost of mission at all. Resolving of this problem may be found by using respective modern technologies and methods which widely used in different branches and not in the space researches only. Such approaches as Social Networking, Web 2.0 and Enterprise 2.0 look most prospective in this context. The primary goal of the "Phobos-Soil" mission is an investigation of the Phobos which is the Martian moon and particularly its regolith, internal structure, peculiarities of the orbital and proper motion, as well as a number of different scientific measurements and experiments for investigation of the Martian environment. A lot of investigators involved in the mission. Effective collaboration system is key facility for information support of the mission therefore. Further to main goal: communication between users of the system, modern approaches allows using such capabilities as self-organizing community, user generated content, centralized and federative control of the system. Also it may have one unique possibility - knowledge management which is very important for space mission realization. Therefore collaboration support system for "Phobos-Soil" mission designed on the base of multilayer model which includes such levels as Communications, Announcement and Information, Data sharing and Knowledge management. The collaboration support system for "Phobos-Soil" mission will be used as prototype for prospective Russian scientific space missions and the presentation describes its architecture, methodological and technical aspects of its design.

Oil Pollution in the Marine Environment: A 35 Year Perspective of Communicating Broadly

Farrington, J. W.; Tripp, B. W.

2006-12-01

Large accidental oil spills such as the tanker Torrey Canyon off the United Kingdom in 1967 and the Santa Barbara Oil Well Blowout of 1969, and attendant publicity, demonstrated that oil spills could be messy, have adverse effects on birds and other wildlife by oiling, and capture the public attention. However, careful scientific study of oil spills using modern biological sciences methods and modern geochemical analyses were needed to overcome the "out of sight, out of mind" conclusion that all was well when visible oil slicks on the water's surface disappeared. Documenting the long lasting persistence of chemicals from spilled oils and attendant biological effects began with a few dedicated scientists who not only published their findings in the scientific literature, but also made them known in testimony before Congress, in interviews with the press and publishing in magazines designed to communicate science to the public. They served as examples for our own efforts, and those of colleagues, to communicate the magnitude of the chronic input of petroleum compounds to the oceans as a result of the every day use of fossil fuels and how this input was quantitatively much larger than inputs from accidental spills and resulted in contamination of coastal areas near urban harbors and at offshore dumpsites. Over a period of the past thirty years mainly during 1971-2000, we used a combination of participation in review and advisory panels and committees, testimony before Congress, letters to government officials, public lectures, articles in the lay press, print and electronic media interviews, and museum exhibits to communicate the message from our scientific papers in ways that could be understood by the general public and acted on by their elected and appointed officials. Lessons learned from these efforts will be summarized

A Parallel Numerical Micromagnetic Code Using FEniCS

NASA Astrophysics Data System (ADS)

Nagy, L.; Williams, W.; Mitchell, L.

2013-12-01

Many problems in the geosciences depend on understanding the ability of magnetic minerals to provide stable paleomagnetic recordings. Numerical micromagnetic modelling allows us to calculate the domain structures found in naturally occurring magnetic materials. However the computational cost rises exceedingly quickly with respect to the size and complexity of the geometries that we wish to model. This problem is compounded by the fact that the modern processor design no longer focuses on the speed at which calculations are performed, but rather on the number of computational units amongst which we may distribute our calculations. Consequently to better exploit modern computational resources our micromagnetic simulations must "go parallel". We present a parallel and scalable micromagnetics code written using FEniCS. FEniCS is a multinational collaboration involving several institutions (University of Cambridge, University of Chicago, The Simula Research Laboratory, etc.) that aims to provide a set of tools for writing scientific software; in particular software that employs the finite element method. The advantages of this approach are the leveraging of pre-existing projects from the world of scientific computing (PETSc, Trilinos, Metis/Parmetis, etc.) and exposing these so that researchers may pose problems in a manner closer to the mathematical language of their domain. Our code provides a scriptable interface (in Python) that allows users to not only run micromagnetic models in parallel, but also to perform pre/post processing of data.

Methods of teaching the physics of climate change in undergraduate physics courses

NASA Astrophysics Data System (ADS)

Sadler, Michael

2015-04-01

Although anthropogenic climate change is generally accepted in the scientific community, there is considerable skepticism among the general population and, therefore, in undergraduate students of all majors. Students are often asked by their peers, family members, and others, whether they ``believe'' climate change is occurring and what should be done about it (if anything). I will present my experiences and recommendations for teaching the physics of climate change to both physics and non-science majors. For non-science majors, the basic approach is to try to develop an appreciation for the scientific method (particularly peer-reviewed research) in a course on energy and the environment. For physics majors, the pertinent material is normally covered in their undergraduate courses in modern physics and thermodynamics. Nevertheless, it helps to review the basics, e.g. introductory quantum mechanics (discrete energy levels of atomic systems), molecular spectroscopy, and blackbody radiation. I have done this in a separate elective topics course, titled ``Physics of Climate Change,'' to help the students see how their knowledge gives them insight into a topic that is very volatile (socially and politically).

Ethnopharmacology, or the scientific validation of traditional medicine, is a respected starting point in drug discovery. Home remedies and traditional use of plants are still widespread, also in Western societies. Instead of perusing ancient pharmacopeias, we developed MedCrawler, which we used to analyze blog posts for mentions of home remedies and their applications. This method is free and accessible from the office computer. We developed MedCrawler, a data mining tool for analyzing user-generated blog posts aiming to find modern 'traditional' medicine or home remedies. It searches user-generated blog posts and analyzes them for correlations between medically relevant terms. We also present examples and show that this method is capable of delivering both scientifically validated uses as well as not so well documented applications, which might serve as a starting point for follow-up research.

[Crisis in medical ethics].

There is a disproportion between diagnostic and therapeutic medical achievements and the doctor/patient relationship. Are we allowed to do everything we are able to do in medicine? People are concerned and worried (genetic technology, invasive medicine, embryos in test tubes etc.). The crisis of ethics in medicine is evident. The analysis of the situation shows one of the causes in the shift of the paradigma-modern times to postmodern following scientific positivism-but also a loss of ethics in medicine due to an extreme secularism and to modern philosophical trends (Hans Jonas and the responsibility for the future and on the other hand modern utilitarism).

From Topos to Oikos: The Standardization of Glass Containers as Epistemic Boundaries in Modern Laboratory Research (1850-1900).

PubMed

Espahangizi, Kijan

2015-09-01

Glass vessels such as flasks and test tubes play an ambiguous role in the historiography of modern laboratory research. In spite of the strong focus on the role of materiality in the last decades, the scientific glass vessel - while being symbolically omnipresent - has remained curiously neglected in regard to its materiality. The popular image or topos of the transparent, neutral, and quasi-immaterial glass container obstructs the view of the physico-chemical functionality of this constitutive inner boundary in modern laboratory environments and its material historicity. In order to understand how glass vessels were able to provide a stable epistemic containment of spatially enclosed experimental phenomena in the new laboratory ecologies emerging in the nineteenth and early twentieth century, I will focus on the history of the material standardization of laboratory glassware. I will follow the rise of a new awareness for measurement errors due to the chemical agency of experimental glass vessels, then I will sketch the emergence of a whole techno-scientific infrastructure for the improvement of glass container quality in late nineteenth-century Germany. In the last part of my argument, I will return to the laboratory by looking at the implementation of this glass reform that created a new oikos for the inner experimental milieus of modern laboratory research.

Code Modernization of VPIC

Bird, Robert; Nystrom, David; Albright, Brian

2017-10-01

The ability of scientific simulations to effectively deliver performant computation is increasingly being challenged by successive generations of high-performance computing architectures. Code development to support efficient computation on these modern architectures is both expensive, and highly complex; if it is approached without due care, it may also not be directly transferable between subsequent hardware generations. Previous works have discussed techniques to support the process of adapting a legacy code for modern hardware generations, but despite the breakthroughs in the areas of mini-app development, portable-performance, and cache oblivious algorithms the problem still remains largely unsolved. In this work we demonstrate how a focus on platform agnostic modern code-development can be applied to Particle-in-Cell (PIC) simulations to facilitate effective scientific delivery. This work builds directly on our previous work optimizing VPIC, in which we replaced intrinsic based vectorisation with compile generated auto-vectorization to improve the performance and portability of VPIC. In this work we present the use of a specialized SIMD queue for processing some particle operations, and also preview a GPU capable OpenMP variant of VPIC. Finally we include a lessons learnt.

Vittorio Marchi was an Italian neuroscientist who lived during the second half of the 19th century. He is generally remembered for developing a novel staining method to trace the degeneration of nervous fibers in lesions of the central nervous system. This osmium-based method was used worldwide for approximately a century and continues to be cited in modern textbooks. Despite several important original scientific contributions, Marchi was never awarded a university chair. Discouraged, he left to practice neurology in a rural area but continued to write outstanding articles, and in 1897, he became a pioneer of meningioma surgery. Today, he is remembered only in specialized contexts. We hope this article can provide the recognition that Marchi deserves.

Overcoming the momentum of anachronism: American geologic mapping in a twenty-first-century world

2013-01-01

The practice of geologic mapping is undergoing conceptual and methodological transformation. Profound changes in digital technology in the past 10 yr have potential to impact all aspects of geologic mapping. The future of geologic mapping as a relevant scientific enterprise depends on widespread adoption of new technology and ideas about the collection, meaning, and utility of geologic map data. It is critical that the geologic community redefine the primary elements of the traditional paper geologic map and improve the integration of the practice of making maps in the field and office with the new ways to record, manage, share, and visualize their underlying data. A modern digital geologic mapping model will enhance scientific discovery, meet elevated expectations of modern geologic map users, and accommodate inevitable future changes in technology.

2014-01-01

The paper reconstructs the scientific career of Ruggero Ceppellini, focusing especially on his role in the discovery of the genetic system underlying the Human Leucocyte Antigen. From his earliest investigations in blood group genetics, Ceppellini quickly became an internationally acknowledged authority in the field of immunogenetics--the study of genetics by means of immunological tools--and participated to the endeavor that ultimately yelded a new meaning for the word: thanks to the pioneering research in the HLA field, immunogenetics became the study of the genetic control of immune system. The paper will also place Ceppellini's scientific work against the backdrop of the modernization of Italian genetics after WWII, resulting from the efforts of a handful of scientists to connect to international networks and adopting new methodologies in life sciences.

Hippocrates' complaint and the scientific ethos in early modern England.

PubMed

Yeo, Richard

2018-04-01

Among the elements of the modern scientific ethos, as identified by R.K. Merton and others, is the commitment of individual effort to a long-term inquiry that may not bring substantial results in a lifetime. The challenge this presents was encapsulated in the aphorism of the ancient Greek physician, Hippocrates of Kos: vita brevis, ars longa (life is short, art is long). This article explores how this complaint was answered in the early modern period by Francis Bacon's call for the inauguration of the sciences over several generations, thereby imagining a succession of lives added together over time. However, Bacon also explored another response to Hippocrates: the devotion of a 'whole life', whether brief or long, to science. The endorsement of long-term inquiry in combination with intensive lifetime involvement was embraced by some leading Fellows of the Royal Society, such as Robert Boyle and Robert Hooke. The problem for individuals, however, was to find satisfaction in science despite concerns, in some fields, that current observations and experiments would not yield material able to be extended by future investigations.

The comeback of hand drawing in modern life sciences.

PubMed

Chabrier, Renaud; Janke, Carsten

2018-03-01

Scientific manuscripts are full of images. Since the birth of the life sciences, these images were in a form of hand drawings, with great examples from da Vinci, Hooke, van Leeuwenhoek, Remak, Buffon, Bovery, Darwin, Huxley, Haeckel and Gray's Anatomy to name a few. However, in the course of the past century, photographs and simplified schematics have gradually taken over as a way of illustrating scientific data and concepts, assuming that these are 'accurate' representations of the truth. Here, we argue for the importance of reviving the art of scientific drawings as a way of effectively communicating complex scientific ideas to both specialists and the general public.

The need for data standards in zoomorphology.

PubMed

Vogt, Lars; Nickel, Michael; Jenner, Ronald A; Deans, Andrew R

2013-07-01

eScience is a new approach to research that focuses on data mining and exploration rather than data generation or simulation. This new approach is arguably a driving force for scientific progress and requires data to be openly available, easily accessible via the Internet, and compatible with each other. eScience relies on modern standards for the reporting and documentation of data and metadata. Here, we suggest necessary components (i.e., content, concept, nomenclature, format) of such standards in the context of zoomorphology. We document the need for using data repositories to prevent data loss and how publication practice is currently changing, with the emergence of dynamic publications and the publication of digital datasets. Subsequently, we demonstrate that in zoomorphology the scientific record is still limited to published literature and that zoomorphological data are usually not accessible through data repositories. The underlying problem is that zoomorphology lacks the standards for data and metadata. As a consequence, zoomorphology cannot participate in eScience. We argue that the standardization of morphological data requires i) a standardized framework for terminologies for anatomy and ii) a formalized method of description that allows computer-parsable morphological data to be communicable, compatible, and comparable. The role of controlled vocabularies (e.g., ontologies) for developing respective terminologies and methods of description is discussed, especially in the context of data annotation and semantic enhancement of publications. Finally, we introduce the International Consortium for Zoomorphology Standards, a working group that is open to everyone and whose aim is to stimulate and synthesize dialog about standards. It is the Consortium's ultimate goal to assist the zoomorphology community in developing modern data and metadata standards, including anatomy ontologies, thereby facilitating the participation of zoomorphology in eScience.

Charles Edouard Brown-Séquard's departure from the Medical College of Virginia: incompatible science or incompatible social views in pre-Civil War southern United States.

Watson, Joseph C; Ho, Stephen V

2011-01-01

Charles Edouard Brown-Séquard was one of the most colorful characters in modern physiology. His scientific methods of self-experimentation and animal vivisection led to many great observations, including the eponymous syndrome of hemisection of the spinal cord. Despite his renown, he stayed but one year in his first major academic post. Details of his sojourn at the Medical College of Virginia (now part of Virginia Commonwealth University) in Richmond were divined from perusal of archival material, letters, and from the available literature. His notoriety in the field of physiology landed him a post at the Medical College of Virginia in 1854 as the chair of physiology. During a brief time here, he was able to publish his landmark monograph of 1855 on the pathways of the spinal cord "Experimental and Clinical Researches on the Physiology and Pathology of the Spinal Cord." He had a near-death experience while experimenting on himself to determine the function of the skin. It was rumored that his English was poor, his lectures unintelligible, and his scientific methods disturbing to the neighbors and that for those reasons he was asked to vacate his post. Personal communications and other accounts indicate a different view: his mixed-blood heritage and his views on slavery were unpopular in the pre-Civil War southern United States. These disparate viewpoints lend an insight into the life and career of this pioneer in modern medicine and experimental design and to the clash of science and social views.

2011-01-01

The term 'science driver' was first used in the 1980s. The modern meaning of 'science' is far removed from its meaning in the first centuries of the telescope. It is anachronistic to refer to the 'science driver' of a historic telescope. However, there were scientific motivations behind many early telescopes, large reflectors in particular. The chronology of larger and improved telescopes will be placed in the context of the rationale for their creation. The evolution of scientific purpose of these instruments will be extracted and examined for patterns and significance.

In treatment procedure apparatus can be applied together with expanded module "Intratherm" (39 °C on average), which has rectal heating elements. The latest clinical studies were made together with volunteer participation of more then one hundred patients, and received results showed the good dynamic of healing. That let to conclude these combinations of physical therapeutic methods supplement each other and in conjunction provides a significant clinical effect. The further developments of such apparatuses are discussed.

Scientific Visualization to Study Flux Transfer Events at the Community Coordinated Modeling Center

2011-01-01

In this paper we present results of modeling of reconnection at the dayside magnetopause with subsequent development of flux transfer event signatures. The tools used include new methods that have been added to the suite of visualization methods that are used at the Community Coordinated Modeling Center (CCMC). Flux transfer events result from localized reconnection that connect magnetosheath magnetic field and plasma with magnetospheric fields and plasma and results in flux rope structures that span the dayside magnetopause. The onset of flux rope formation and the three-dimensional structure of flux ropes are studied as they have been modeled by high-resolution magnetohydrodynamic simulations of the dayside magnetosphere of the Earth. We show that flux transfer events are complex three-dimensional structures that require modern visualization and analysis techniques. Two suites of visualization methods are presented and we demonstrate the usefulness of those methods through the CCMC web site to the general science user.

The combination of modern scientific computing with electronic structure theory can lead to an unprecedented amount of data amenable to intelligent data analysis for the identification of meaningful, novel and predictive structure-property relationships. Such relationships enable high-throughput screening for relevant properties in an exponentially growing pool of virtual compounds that are synthetically accessible. Here, we present a machine learning model, trained on a database of ab initio calculation results for thousands of organic molecules, that simultaneously predicts multiple electronic ground- and excited-state properties. The properties include atomization energy, polarizability, frontier orbital eigenvalues, ionization potential, electron affinity and excitation energies. The machine learning model is based on a deep multi-task artificial neural network, exploiting the underlying correlations between various molecular properties. The input is identical to ab initio methods, i.e. nuclear charges and Cartesian coordinates of all atoms. For small organic molecules, the accuracy of such a ‘quantum machine’ is similar, and sometimes superior, to modern quantum-chemical methods—at negligible computational cost.

The Nature of Science and the Role of Knowledge and Belief

NASA Astrophysics Data System (ADS)

Cobern, William W.

In everyday language we tend to think of knowledge as reasoned belief that a proposition is true and the natural sciences provide the archetypal example of what it means to know. Religious and ideological propositions are the typical examples of believed propositions. Moreover, the radical empiricist worldview so often associated with modern science has eroded society's meaningful sense of life. Western history, however, shows that knowledge and belief have not always been constructed separately. In addition, modern developments in the philosophy and history of science have seriously undermined the radical empiricist's excessive confidence in scientific methods. Acknowledging in the science classroom the parallel structure of knowledge and belief, and recognizing that science requires a presuppositional foundation that is itself not empirically verifiable would re introduce a valuable discussion on the meaning of science and its impact on life. Science would less likely be taught as a `rhetoric of conclusions'. The discussion would also help students to gain a firmer integration of science with other important knowledge and beliefs that they hold.

Planetary Exploration in the Classroom

We have developed educational materials to seed a series of undergraduate level exercises on "Planetary Exploration in the Classroom." The goals of the series are to teach modern methods of planetary exploration and discovery to students having both science and non-science backgrounds. Using personal computers in a "hands-on" approach with images recorded by planetary spacecraft, students working through the exercises learn that modern scientific images are digital objects that can be examined and manipulated in quantitative detail. The initial exercises we've developed utilize NIH Image in conjunction with images from the Voyager spacecraft CDs. Current exercises are titled "Using 'NIH IMAGE' to View Voyager Images", "Resolving Surface Features on Io", "Discovery of Volcanoes on Io", and "Topography of Canyons on Ariel." We expect these exercises will be released during Fall 1997 and will be available via 'anonymous ftp'; detailed information about obtaining the exercises will be on the Web at "http://web.mit.edu/12s23/www/pec.html." This curriculum development was sponsored by NSF Grant DUE-9455329.

Bioenhancers from mother nature and their applicability in modern medicine

PubMed Central

Randhawa, Gurpreet Kaur; Kullar, Jagdev Singh; Rajkumar

2011-01-01

Concept of bioenhancers or biopotentiators was first time reported in 1929 by Bose. A bioenhancer is an agent capable of enhancing bioavailability and efficacy of a drug with which it is co-administered, without any pharmacological activity of its own at therapeutic dose used. Development and consequent isolation of these molecules, such as piperine and quercetin, is considered as scientific breakthrough. A fixed drug combination (Risorine) of rifampicin, isoniazid, and piperine is the result of this research. It contains almost 60% less dose of rifampicin because of its increased bioavailability and it also prevents resistance. This concept is mentioned as yogvahi in ayurveda and was used to increase the effect of medicines by increasing oral bioavailability, decreasing adverse effects and to circumvent parenteral routes of drug administration. More such useful and economically viable drug combinations can be developed by integrating knowledge of time tested ayurveda with modern methods of research. This review is an account of these bioenhancers, available from the natural resources. PMID:23776764

An Automatic Image-Based Modelling Method Applied to Forensic Infography

PubMed Central

Zancajo-Blazquez, Sandra; Gonzalez-Aguilera, Diego; Gonzalez-Jorge, Higinio; Hernandez-Lopez, David

2015-01-01

This paper presents a new method based on 3D reconstruction from images that demonstrates the utility and integration of close-range photogrammetry and computer vision as an efficient alternative to modelling complex objects and scenarios of forensic infography. The results obtained confirm the validity of the method compared to other existing alternatives as it guarantees the following: (i) flexibility, permitting work with any type of camera (calibrated and non-calibrated, smartphone or tablet) and image (visible, infrared, thermal, etc.); (ii) automation, allowing the reconstruction of three-dimensional scenarios in the absence of manual intervention, and (iii) high quality results, sometimes providing higher resolution than modern laser scanning systems. As a result, each ocular inspection of a crime scene with any camera performed by the scientific police can be transformed into a scaled 3d model. PMID:25793628

An integrative perspective of the anaerobic threshold.

The concept of anaerobic threshold (AT) was introduced during the nineteen sixties. Since then, several methods to identify the anaerobic threshold (AT) have been studied and suggested as novel 'thresholds' based upon the variable used for its detection (i.e. lactate threshold, ventilatory threshold, glucose threshold). These different techniques have brought some confusion about how we should name this parameter, for instance, anaerobic threshold or the physiological measure used (i.e. lactate, ventilation). On the other hand, the modernization of scientific methods and apparatus to detect AT, as well as the body of literature formed in the past decades, could provide a more cohesive understanding over the AT and the multiple physiological systems involved. Thus, the purpose of this review was to provide an integrative perspective of the methods to determine AT. Copyright © 2017 Elsevier Inc. All rights reserved.

The main aim of the article was to present research on the application of computer image analysis in Life Science and Environmental Engineering. The authors used different methods of computer image analysis in developing of an innovative biotest in modern biomonitoring of water quality. Created tools were based on live organisms such as bioindicators Lemna minor L. and Hydra vulgaris Pallas as well as computer image analysis method in the assessment of negatives reactions during the exposition of the organisms to selected water toxicants. All of these methods belong to acute toxicity tests and are particularly essential in ecotoxicological assessment of water pollutants. Developed bioassays can be used not only in scientific research but are also applicable in environmental engineering and agriculture in the study of adverse effects on water quality of various compounds used in agriculture and industry.

Ethical issues in forecasting of natural hazards

NASA Astrophysics Data System (ADS)

Tinti, Stefano

2014-05-01

Natural hazards have by definition a large impact on the society and, therefore, since the beginning of science one of the major aspiration of mankind has been the prediction of natural calamities in the attempt to avoid or to mitigate their effects. In modern societies where science and technology have gained a foundational role, forecasts and predictions have become part of the every-day life and may also influence state policies and economic development. And in parallel with the growing importance of forecasting, even ethical problems for forecasters and for forecasters communities have started to appear. In this work two of the many geo-ethical issues are considered mostly: 1) how to cope with uncertainties that are inherently associated with any forecast statement; 2) how to handle predictions in scientific journals and scientific conferences The former issue is mainly related to the impact of predictions on the general public and on managers and operators in the civil protection field. Forecasters operate in specific contexts that 1) may change from country to country, depending on the local adopted best practices, but also, which is more constraining, on the local legal regulations and laws; 2) may change from discipline to discipline according to the development of the specific knowhow and the range of the forecast (from minutes to centuries) The second issue has to do with the communication of the scientific results on predictions and on prediction methods to the audience mainly composed of scientists, and involves one of the basic elements of science. In principle, scientists should use scientific communication means (papers in scientific journals, conferences, …) to illustrate results that are sound and certain, or the methods by means of which they conduct their research. But scientists involved in predictions have inherently to do with uncertainties, and, since there is no common agreement on how to deal with them, there is the risk that scientific results may be confused with opinions and opinions with scientific results, which creates confusion in the scientific community, in the science divulgators and in turn in the general public.

Bruteau's philosophy of spiritual evolution and consciousness: foundation for a nursing cosmology.

PubMed

McCarthy, M Patrice

2011-01-01

The ontological foundation of the modern world view based on irreconcilable dichotomies has held hegemonic status since the dawn of the scientific revolution. The post-modern critique has exposed the inadequacies of the modern perspective and challenged the potential for any narrative to adequately ground a vision for the future. This paper proposes that the philosophy of Beatrice Bruteau can support a foundation for a visionary world view consistent with nursing's respect for human dignity and societal health. The author discusses the key concepts of Bruteau's perspective on societal evolution based on an integrated study of science, mathematics, religion, and philosophy. This perspective is discussed as a foundation to move beyond the dichotomous influence of the modern world view and the deconstructive critique of the post-modern perspective. The author suggests spiritual evolution and a participatory consciousness as an ontological foundation for a cosmology congruent with nursing's social mandate. © 2010 Blackwell Publishing Ltd.

Formalization and Interaction: Toward a Comprehensive History of Technology-Related Knowledge in Early Modern Europe.

PubMed

Popplow, Marcus

2015-12-01

Recent critical approaches to what has conventionally been described as "scientific" and "technical" knowledge in early modern Europe have provided a wealth of new insights. So far, the various analytical concepts suggested by these studies have not yet been comprehensively discussed. The present essay argues that such comprehensive approaches might prove of special value for long-term and cross-cultural reflections on technology-related knowledge. As heuristic tools, the notions of "formalization" and "interaction" are proposed as part of alternative narratives to those highlighting the emergence of "science" as the most relevant development for technology-related knowledge in early modern Europe.

Assessing the Role of Technology in Citizen Science: A Volunteer's Perspective

NASA Astrophysics Data System (ADS)

Wei, J. H.; Force, A.

2017-12-01

From a volunteer's perspective, citizen science can provide a direct connection between outdoor enthusiasts and the scientists who study these natural environments. These experiences are both rewarding and engaging, as participants become aware of field sites, the scientific method, and their own environmental impacts. Recent technological advances (i.e. smart phones and mobile applications) have the potential to transform citizen science, specifically as technology can both enable and modernize the networks between a large community of potential volunteers and scientists using these data. By providing volunteers who venture into largely understudied and remote areas with an easy method for data collection and entry, it becomes easier to encourage volunteer engagement in science, while maintaining quality control over the data collection process. Participating in Adventure Scientists' projects demonstrates the application of technology as an effective engagement tool, especially when compared to traditional pen and paper surveys often conducted. Pairing volunteers with simple, familiar technology increases engagement, particularly for volunteers otherwise intimidated by the scientific process. When equipped with useful features, such as GPS functionality, smartphone apps offer a simple and standardized method of data collection and description. Yet a variety of factors can complicate field sampling; final choices are ultimately left to the judgment of the volunteer and perhaps could be guided by use of a phone/app. Importantly, Adventure Scientists conducts follow ups and volunteer surveys, which are critical to the continued evaluation of volunteer experiences and the sampling methods themselves. For future projects, creating a forum in which scientists and volunteers can interact (perhaps also through a phone app) could provide scientific context for volunteers, further investing them in the scientific process and their continued participation. Overall, the Adventure Scientists' approach provides a model for connecting science with the growing outdoor recreation community; by embracing technology already in our pockets, scientists can hope to connect with more participants and future generations to come.

Ghost and self: Jung's paradigm shift and a response to Zinkin.

PubMed

Rowland, Susan

2009-11-01

Zinkin's lucid challenge to Jung makes perfect sense. Indeed, it is the implications of this 'making sense' that this paper addresses. For Zinkin's characterization of the 'self' takes it as a 'concept' requiring coherence; a variety of abstract non-contextual knowledge that itself has a mythical heritage. Moreover, Zinkin's refinement of Jung seeks to make his work fit for the scientific paradigm of modernity. In turn, modernity's paradigm owes much to Newton's notion of knowledge via reductionism. Here knowledge or investigation is divided up into the smallest possible units with the aim of eventually putting it all together into 'one' picture of scientific truth. Unfortunately, 'reductionism' does not do justice to the resonant possibilities of Jung's writing. These look forward to a new scientific paradigm of the twenty-first century, of the interactive 'field', emergence and complexity theory. The paper works paradoxically by discovering Zinkin's 'intersubjective self' after all, in two undervalued narratives by Jung, his doctoral thesis and a short late ghost story. However, in the ambivalences and radical fictional experimentation of these fascinating texts can be discerned an-Other self, one both created and found.

The French Jesuit Mission to Thailand in the 1680s and the Establishment of a Major Astronomical Observatory

2012-09-01

The first great Thai ruler to encourage the adoption of Western culture and technology was King Narai, and his enlightened attitude led to the rapid development of Thailand. King Narai also had a passion for astronomy, and he pursued this interest by allowing French Jesuit missionaries to set up a large modern well-equipped astronomical observatory in Lopburi Province between AD 1685 and 1687. This was known as the Wat San Paolo Observatory, and King Narai and the missionaries observed a total lunar eclipse on 10 December 1685 and a partial solar eclipse on 30 April 1688. These observations and others made at Wat San Paolo Observatory during the 1680s marked the start of modern scientific astronomy in Thailand. In this paper we discuss King Narai's scientific and other interests, the founding of the Wat San Paolo Observatory, the missionaries who conducted the astronomical programs, their instruments and their observations. We also describe the surviving ruins of the Observatory and their interpretation as a site of national scientific importance in Thailand.

Challenging Expertise: Paul Feyerabend vs. Harry Collins & Robert Evans on democracy, public participation and scientific authority: Paul Feyerabend vs. Harry Collins & Robert Evans on scientific authority and public participation.

PubMed

Sorgner, Helene

2016-06-01

This paper compares Feyerabend's arguments in Science in a Free Society to the controversial theory of expertise proposed by Harry Collins and Robert Evans as a Third Wave of Science Studies. Is the legitimacy of democratic decisions threatened by the unquestioned authority of scientific advice? Or does, on the contrary, science need protection from too much democratic participation in technical decisions? Where Feyerabend's political relativism envisions democratic society as inherently pluralist and demands equal contribution of all traditions and worldviews to public decision-making, Collins and Evans hold a conception of elective modernism, defending the reality and value of technical expertise and arguing that science deserves a privileged status in modern democracies, because scientific values are also democratic values. I will argue that Feyerabend's political relativism provides a valuable framework for the evaluation of Collins' and Evans' theory of expertise. By constructing a dialog between Feyerabend and this more recent approach in Science and Technology Studies, the aim of this article is not only to show where the two positions differ and in what way they might be reconciled, but also how Feyerabend's philosophy provides substantial input to contemporary debate.

The ubiquitous reflex and its critics in post-revolutionary Russia.

PubMed

Sirotkina, Irina

2009-03-01

In the last century, the reflex was more than a scientific concept: it was a cultural idiom that could be used to various aims--political, scholarly, and artistic. In Russia in the 1920s, the reflex became a ubiquitous notion and a current word, part of the revolutionary discourse and, finally, a password to modernity. Two major factors contributed to it: physiological theories of the reflex, widespread in Russia at the early twentieth-century, and the materialist philosophy backed after the Revolution by the Communist party. Everybody who wished to be modern and materialist, in conformity with the official communist views, had to refer to reflexes. Yet, even in this period, the concept was not unproblematic and was criticized by some scientists, philosophers, artists and even Party members. In the paper, I describe both the array of uses of the term and the criticism it received in political, scientific and artistic discourses. It is not uncommon that, taking their origins in culture and common language, scientific concepts later return there in the form of metaphors. Similarly, the reflex was made into a rigorous scientific concept in the nineteenth century but, in the next century, it circulated as a cultural idiom penetrating various areas of political, artistic and academic life.

Making medicine scientific: empiricism, rationality, and quackery in mid-Victorian Britain.

PubMed

Weatherall, M W

1996-08-01

This paper discusses the strategies used to construct scientific medicine in mid-Victorian Britain. An opening section considers why it was thought desirable to create a properly scientific medicine, and outlines the empirical and rational bases of the medical establishment's projects for this. The bulk of the paper concerns an alternative approach to making medicine scientific--that put forward by certain advocates of homoeopathy--and how this approach was excluded from those arenas where scientific medicine was being created, and thereby made unscientific. This process is illustrated by the clash between homoeopathy and establishment medicine that occurred in mid-Victorian Cambridge. The final section briefly considers the complementary process of educating the public in what was properly scientific medicine, and what was not, and suggests that the processes of building boundaries to exclude competing practitioners, while keeping patients inside, created the space in which modern scientific medicine has flourished so successfully.

And yet, we were modern. The paradoxes of Iberian science after the Grand Narratives.

PubMed

Pimentel, Juan; Pardo-Tomás, José

2017-06-01

In this article, we try to explain the origin of a disagreement; the sort that often arises when the subject is the history of early modern Spanish science. In the decades between 1970 and 1990, while some historians were trying to include Spain in the grand narrative of the rise of modern science, the very historical category of the Scientific Revolution was beginning to be dismantled. It could be said that Spaniards were boarding the flagship of modern science right before it sank. To understand this décalage it would be helpful to recall the role of the history of science during the years after the Franco dictatorship and Spain's transition to democracy. It was a discipline useful for putting behind us the Black Legend and Spanish exceptionalism.

Listmania. How lists can open up fresh possibilities for research in the history of science.

PubMed

Delbourgo, James; Müller-Wille, Staffan

2012-12-01

Anthropologists, linguists, cultural historians, and literary scholars have long emphasized the value of examining writing as a material practice and have often invoked the list as a paradigmatic example thereof. This Focus section explores how lists can open up fresh possibilities for research in the history of science. Drawing on examples from the early modern period, the contributors argue that attention to practices of list making reveals important relations between mercantile, administrative, and scientific attempts to organize the contents of the world. Early modern lists projected both spatial and temporal visions of nature: they inventoried objects in the process of exchange and collection; they projected possible trajectories for future endeavor; they publicized the social identities of scientific practitioners; and they became research tools that transformed understandings of the natural order.

A study of the information seeking behaviour of hospital pharmacists: empirical evidence from Greece.

2011-12-01

Hospital pharmacists need access to high-quality information in order to constantly update their knowledge and improve their skills. In their modern role, they are expected to address three types of challenges: scientific, organizational and administrative, thus having an increased need for adequate information and library services. This study investigates the information-seeking behaviour of public hospital pharmacists providing evidence from Greece that could be used to encourage the development of effective information hospital services and study the links between the information seeking behaviour of hospital pharmacists and their modern scientific and professional role. An empirical research was conducted between January and February 2010 with the development and distribution of a structured questionnaire. The questionnaire was filled in and returned by 88 public hospital pharmacists from a total of 286 working in all Greek public hospitals, providing a response rate of 31%. The hospital pharmacists in Greece are in search of scientific information and, more particularly, pharmaceutical information (e.g., drug indications, storage, dosage and prices). The Internet and the National Organization of Medicines are their main information sources, while the lack of time and organized information are the main obstacles they have to face when seeking information. The modern professional role of hospital pharmacists as invaluable contributors to efficient and safer healthcare services may be further supported through the development of specialized libraries and information services within Greek public hospitals. © 2011 The authors.

Genetic engineering applied to agriculture has a long row to hoe.

Miller, Henry I

2018-01-02

In spite of the lack of scientific justification for skepticism about crops modified with molecular techniques of genetic engineering, they have been the most scrutinized agricultural products in human history. The assumption that "genetically engineered" or "genetically modified" is a meaningful - and dangerous - classification has led to excessive and dilatory regulation. The modern molecular techniques are an extension, or refinement, of older, less precise, less predictable methods of genetic modification, but as long as today's activists and regulators remain convinced that so called "GMOs" represent a distinct and dangerous category of research and products, genetic engineering will fall short of its potential.

Analytical methods of haloanisoles and halophenols quantification in cork matrix are summarized in the current review. Sample-preparation and sample-treatment techniques have been compared and discussed from the perspective of their efficiency, time- and extractant-optimization, easiness of performance. Primary interest of these analyses usually addresses to 2,4,6-trichloroanisole (TCA), which is a major wine contaminant among haloanisoles. Two concepts of TCA determination are described in the review: releasable TCA and total TCA analyses. Chromatographic, bioanalytical and sensorial methods were compared according to their application in the cork industry and in scientific investigations. Finally, it was shown that modern analytical techniques are able to provide required sensitivity, selectivity and repeatability for haloanisoles and halophenols determination.

The most recent results include showing that the set of magnetic field functions that are omnigenous (i.e., the bounce-average drift lies within the flux surface) and, therefore, have good transport properties, is much larger than the set of quasihelical systems. This is important as quasihelical systems exist only for large aspect ratio.

Modern biological experiments create vast amounts of data which are geographically distributed. These datasets consist of petabytes of raw data and billions of documents. Yet to the best of our knowledge, a search engine technology that searches and cross-links all different data types in life sciences does not exist. We have developed a prototype distributed scientific search engine technology, 'Sciencenet', which facilitates rapid searching over this large data space. By 'bringing the search engine to the data', we do not require server farms. This platform also allows users to contribute to the search index and publish their large-scale data to support e-Science. Furthermore, a community-driven method guarantees that only scientific content is crawled and presented. Our peer-to-peer approach is sufficiently scalable for the science web without performance or capacity tradeoff. The free to use search portal web page and the downloadable client are accessible at: http://sciencenet.kit.edu. The web portal for index administration is implemented in ASP.NET, the 'AskMe' experiment publisher is written in Python 2.7, and the backend 'YaCy' search engine is based on Java 1.6.

The impact of the Daubert case on modern litigation.

PubMed

Mavroforou, Anna; Michalodimitrakis, Emmanuel

2008-12-01

Numerous product liability and toxic tort verdicts were arguably unjustly made on the basis of "junk science" threatening not only justice but the workings of the American economy. This problem was expected to be solved with the application of Daubert criteria, which require the courts to determine whether an expert's testimony reflects scientific knowledge, whether his/her findings are derived by the scientific method, and whether the work product is based on good science. Moreover, the Daubert criteria were expected to have an extraordinary impact on criminal litigation because there is rarely a criminal trial that does not rely on some form of expert testimony. However, there has been some debate on how such standards should be applied to cases involving relatively new product technologies, which only recently have been approved for a specific use, when an incident occurs and for which no published articles or other peer review summaries exist. Additionally, because most violent crimes are committed by the poor and their court appointed advocates, who are overworked and under-financed, are not up to the challenge. Therefore, with the Daubert standards for the admissibility of scientific evidence in the courts alone no significant improvement is expected. The presence of a system of effective representation in criminal cases along with efforts to educate judges and courts to understand ranges of scientific evidence and to recognise the reasonableness of scientific disagreements in civil and criminal cases are of paramount importance.

A space for learning: how teachers benefit from participating in a professional community of space technology

NASA Astrophysics Data System (ADS)

Mehli, Hanne; Bungum, Berit

2013-04-01

Background Science teachers need a deep understanding of how science works in modern society. Purpose This article reports a case study investigating the ways in which a short-term in-service course on a research site of space technology contributes to this understanding. Design and method The study is performed in three steps: an evaluation immediately after the course, a survey 4-12 months after the course and, finally, in-depth interviews with a selection of course participants. Results The results show that teachers benefit from the course experience in ways considered important for their professional development as science teachers, despite the fact that the course deviates from current recommendations for professional development: the course is not based on the school's immediate needs, it is short term with no follow-up and it does not engage participants in the epistemic aspects of a research project. The teachers' gains are related to the authenticity of the research site, working and being with professionals and having sufficient time to cooperate with them in solving specific tasks towards the goal of launching a rocket. In this way, the course gave teachers authentic experiences and important insights in the complexity and infrastructure of a specific scientific practice in modern society. Conclusions Participating in a scientific community of practice is important for the development of science teachers' subject-related identity, and should be recognised as an important part of their professional development.

Modern Role of Architectural Style Category in Russian Practice

NASA Astrophysics Data System (ADS)

Chudinova, V. G.

2017-11-01

The article examines the functional aspects of architectural style use as an instrument for communication, self-positioning, representation and commercial attractiveness. The modern Russian practice is marked by a predominance of decorating methods rather than architectural ones used to create an artistic image. Specific examples illustrate stylistic trends that are indicative of an identity crisis. The problem goes beyond the scope of a custom or corporate design. This is especially evident in the former Soviet Union republics. The style issue is inherent in the advertising and commercial sphere of interior design and furnishing promotion. One can state that the category of art studies has been introduced into the collective consciousness but in some extrinsic way. Marketing managers and designers who have a very vague idea of the fundamental scientific concepts form a new language and market demand not only for a design work product but also for its positioning. This leads to a semantic distortion of the architectural style characteristic and a misconception. At the same time, there is a growing need for new definitions and verbalizations of perceptual experience. The conclusions contain an assumption on a reversible scientific and practical process when the theory is forced to accept and attend to a spontaneously formed and deep-rooted system of meanings. The need to develop the architectural theory in the communication language realm is brought up. The research problem is stated both for social science and anthropology as well as for culturology and art history.

[On the evolution of scientific thought].

de Micheli, Alfredo; Iturralde Torres, Pedro

2015-01-01

The Nominalists of the XIV century, precursors of modern science, thought that science's object was not the general, vague and indeterminate but the particular, which is real and can be known directly. About the middle of the XVII Century the bases of the modern science became established thanks to a revolution fomented essentially by Galileo, Bacon and Descartes. During the XVIII Century, parallel to the development of the great current of English Empiricism, a movement of scientific renewal also arose in continental Europe following the discipline of the Dutch Physicians and of Boerhaave. In the XIX Century, Claude Bernard dominated the scientific medicine but his rigorous determinism impeded him from taking into account the immense and unforeseeable field of the random. Nowadays, we approach natural science and medicine, from particular groups of facts; that is, from the responses of Nature to specific questions, but not from the general laws. Furthermore, in recent epistemology, the concept that experimental data are not pure facts, but rather, facts interpreted within a hermeneutical context has been established. Finally a general tendency to retrieve philosophical questions concerning the understanding of essence and existence can frequently be seen in scientific inquiry. In the light of the evolution of medical thought, it is possible to establish the position of scientific medicine within the movement of ideas dominating in our time.

The Development of Genetics in the Light of Thomas Kuhn's Theory of Scientific Revolutions.

PubMed

Portin, Petter

2015-01-01

The concept of a paradigm is in the key position in Thomas Kuhn's theory of scientific revolutions. A paradigm is the framework within which the results, concepts, hypotheses and theories of scientific research work are understood. According to Kuhn, a paradigm guides the working and efforts of scientists during the time period which he calls the period of normal science. Before long, however, normal science leads to unexplained matters, a situation that then leads the development of the scientific discipline in question to a paradigm shift--a scientific revolution. When a new theory is born, it has either gradually emerged as an extension of the past theory, or the old theory has become a borderline case in the new theory. In the former case, one can speak of a paradigm extension. According to the present author, the development of modern genetics has, until very recent years, been guided by a single paradigm, the Mendelian paradigm which Gregor Mendel launched 150 years ago, and under the guidance of this paradigm the development of genetics has proceeded in a normal fashion in the spirit of logical positivism. Modern discoveries in genetics have, however, created a situation which seems to be leading toward a paradigm shift. The most significant of these discoveries are the findings of adaptive mutations, the phenomenon of transgenerational epigenetic inheritance, and, above all, the present deeply critical state of the concept of the gene.

History is nowadays used as an economic factor. The past is therefore specifically targeted and cultivated, which for specialist scientific associations and societies often fullfils totally different functions in comparison to the open market, although the techniques and requirements are similar. Within medical specialties these facts are often still unknown. Museums and archives as well as the historians and curators working in them are very familiar with the special cultures of communication within these scientific communities and they play a major role in the establishment and development of history as a modern part of public relations and public identity.

THE MODERN SCIENTIFIC RESEARCH ON THE THEORY OF TRADITIONAL CHINESE MEDICINE

1983-01-01

Traditional Chinese Medicine, unlike in many countries, with its well defined concepts and content, is developed due to the progressive policies of the government. The past 30 years work on scientific lines complemented by the successful and significant efforts to integrate Traditional Chinese Medicine with Western medicine has proved the scientific essence of the theory of this system. Added to this are the social acceptebility, relevance, and effectiveness. This brief review of some of the major work done indicates the bright future it has in contributing to the improvement of the health of the world. PMID:22556966

PREDON Scientific Data Preservation 2014

Diaconu, C.; Kraml, S.; Surace, C.; Chateigner, D.; Libourel, T.; Laurent, A.; Lin, Y.; Schaming, M.; Benbernou, S.; Lebbah, M.; Boucon, D.; Cérin, C.; Azzag, H.; Mouron, P.; Nief, J.-Y.; Coutin, S.; Beckmann, V.

Scientific data collected with modern sensors or dedicated detectors exceed very often the perimeter of the initial scientific design. These data are obtained more and more frequently with large material and human efforts. A large class of scientific experiments are in fact unique because of their large scale, with very small chances to be repeated and to superseded by new experiments in the same domain: for instance high energy physics and astrophysics experiments involve multi-annual developments and a simple duplication of efforts in order to reproduce old data is simply not affordable. Other scientific experiments are in fact unique by nature: earth science, medical sciences etc. since the collected data is "time-stamped" and thereby non-reproducible by new experiments or observations. In addition, scientific data collection increased dramatically in the recent years, participating to the so-called "data deluge" and inviting for common reflection in the context of "big data" investigations. The new knowledge obtained using these data should be preserved long term such that the access and the re-use are made possible and lead to an enhancement of the initial investment. Data observatories, based on open access policies and coupled with multi-disciplinary techniques for indexing and mining may lead to truly new paradigms in science. It is therefore of outmost importance to pursue a coherent and vigorous approach to preserve the scientific data at long term. The preservation remains nevertheless a challenge due to the complexity of the data structure, the fragility of the custom-made software environments as well as the lack of rigorous approaches in workflows and algorithms. To address this challenge, the PREDON project has been initiated in France in 2012 within the MASTODONS program: a Big Data scientific challenge, initiated and supported by the Interdisciplinary Mission of the National Centre for Scientific Research (CNRS). PREDON is a study group formed by researchers from different disciplines and institutes. Several meetings and workshops lead to a rich exchange in ideas, paradigms and methods. The present document includes contributions of the participants to the PREDON Study Group, as well as invited papers, related to the scientific case, methodology and technology. This document should be read as a "facts finding" resource pointing to a concrete and significant scientific interest for long term research data preservation, as well as to cutting edge methods and technologies to achieve this goal. A sustained, coherent and long term action in the area of scientific data preservation would be highly beneficial.

Scientific misconduct: three forms that directly harm others as the modus operandi of Mill's tyranny of the prevailing opinion.

PubMed

Cabbolet, Marcoen J T F

2014-03-01

Scientific misconduct is usually assumed to be self-serving. This paper, however, proposes to distinguish between two types of scientific misconduct: 'type one scientific misconduct' is self-serving and leads to falsely positive conclusions about one's own work, while 'type two scientific misconduct' is other-harming and leads to falsely negative conclusions about someone else's work. The focus is then on the latter type, and three known issues are identified as specific forms of such scientific misconduct: biased quality assessment, smear, and officially condoning scientific misconduct. These concern the improper ways how challenges of the prevailing opinion are thwarted in the modern world. The central issue is pseudoskepticism: uttering negative conclusions about someone else's work that are downright false. It is argued that this may be an emotional response, rather than a calculated strategic action. Recommendations for educative and punitive measures are given to prevent and to deal with these three forms of scientific misconduct.

The art of providing resuscitation in Greek mythology.

2014-12-01

We reviewed Greek mythology to accumulate tales of resuscitation and we explored whether these tales could be viewed as indirect evidence that ancient Greeks considered resuscitation strategies similar to those currently used. Three compendia of Greek mythology: The Routledge Handbook of Greek Mythology, The Greek Myths by Robert Graves, and Greek Mythology by Ioannis Kakridis were used to find potentially relevant narratives. Thirteen myths that may suggest resuscitation (including 1 case of autoresuscitation) were identified. Methods to attempt mythological resuscitation included use of hands (which may correlate with basic life support procedures), a kiss on the mouth (similar to mouth-to-mouth resuscitation), application of burning torches (which might recall contemporary use of external defibrillators), and administration of drugs (a possible analogy to advanced life support procedures). A careful assessment of relevant myths demonstrated that interpretations other than medical might be more credible. Although several narratives of Greek mythology might suggest modern resuscitation techniques, they do not clearly indicate that ancient Greeks presaged scientific methods of resuscitation. Nevertheless, these elegant tales reflect humankind's optimism that a dying human might be restored to life if the appropriate procedures were implemented. Without this optimism, scientific improvement in the field of resuscitation might not have been achieved.

Solving the puzzle: What is behind our forefathers’ anti-inflammatory remedies?

Inflammation is a ubiquitous host response in charge of restoring normal tissue structure and function but is a double-edged sword, as the uncontrolled or excessive process can lead to the injury of host cells, chronic inflammation, chronic diseases, and also neoplastic transformation. Throughout history, a wide range of species has been claimed to have anti-inflammatory effects worldwide. Among them, Angelica sinensis, Tropaeolum majus, Castilleja tenuiflora, Biophytum umbraculum, to name just a few, have attracted the scientific and general public attention in the last years. Efforts have been made to assess their relevance through a scientific method. However, inflammation is a complex interdependent process, and phytomedicines are complex mixtures of compounds with multiple mechanisms of biological actions, which restricts systematic explanation. For this purpose, the omics techniques could prove extremely useful. They provide tools for interpreting and integrating results from both the classical medical tradition and modern science. As a result, the concept of network pharmacology applied to phytomedicines emerged. All of this is a step toward personalized therapy. PMID:28163971

Radiometric dating of the Siloam Tunnel, Jerusalem.

Frumkin, Amos; Shimron, Aryeh; Rosenbaum, Jeff

2003-09-11

The historical credibility of texts from the Bible is often debated when compared with Iron Age archaeological finds (refs. 1, 2 and references therein). Modern scientific methods may, in principle, be used to independently date structures that seem to be mentioned in the biblical text, to evaluate its historical authenticity. In reality, however, this approach is extremely difficult because of poor archaeological preservation, uncertainty in identification, scarcity of datable materials, and restricted scientific access into well-identified worship sites. Because of these problems, no well-identified Biblical structure has been radiometrically dated until now. Here we report radiocarbon and U-Th dating of the Siloam Tunnel, proving its Iron Age II date; we conclude that the Biblical text presents an accurate historic record of the Siloam Tunnel's construction. Being one of the longest ancient water tunnels lacking intermediate shafts, dating the Siloam Tunnel is a key to determining where and when this technological breakthrough took place. Siloam Tunnel dating also refutes a claim that the tunnel was constructed in the second century bc.

Idealisation and Galileo's Pendulum Discoveries: Historical, Philosophical and Pedagogical Considerations

NASA Astrophysics Data System (ADS)

Matthews, Michael R.

2004-11-01

Galileo's discovery of the properties of pendulum motion depended on his adoption of the novel methodology of idealisation. Galileo's laws of pendulum motion could not be accepted until the empiricist methodological constraints placed on science by Aristotle, and by common sense, were overturned. As long as scientific claims were judged by how the world was immediately seen to behave, and as long as mathematics and physics were kept separate, then Galileo's pendulum claims could not be substantiated; the evidence was against them. Proof of the laws required not just a new science, but a new way of doing science, a new way of handling evidence, a new methodology of science. This was Galileo's method of idealisatioin. It was the foundation of the Galilean-Newtonian Paradigm which characterised the Scientific Revolution of the 17th century, and the subsequent centuries of modern science. As the pendulum was central to Galileo's and Newton's physics, appreciating the role of idealisation in their work is an instructive way to learn about the nature of science.

Studies in Historical Replication in Psychology VII: The Relative Utility of ``Ancestor Analysis'' from Scientific and Educational Vantages

NASA Astrophysics Data System (ADS)

Ranney, Michael Andrew

2008-05-01

This article discusses, from various vantages, Ryan Tweney’s (this issue) pedagogical technique of employing historical replications of psychological experiments with graduate students in psychology. A prima facie perspective suggests great promise for this sort of academic “ancestor analysis,” particularly given the enthusiasm and skill represented in the activities that culminated in the replicators’ articles. It is suggested that such activities might be enhanced by requiring a contextualization that makes contact with more modern psychological research—particularly regarding expositions of the replications. From a scientific/cognitive methods perspective, the original experimenters’ inexplicit, ambiguous, descriptions provide both challenges and opportunities for students seeking to improve their understandings of their field. Three practical questions are posed herein regarding the general utility of this—or any—proposed instructional intervention. Ultimately, determining and integrating the diverse objectives that essential stakeholders have in graduate psychological training represent critical prerequisites in comprehensively assessing the relative advantages of such historical replications with respect to alternative experiences.

Changing techniques in crop plant classification: molecularization at the National Institute of Agricultural Botany during the 1980s.

Holmes, Matthew

2017-04-01

Modern methods of analysing biological materials, including protein and DNA sequencing, are increasingly the objects of historical study. Yet twentieth-century taxonomic techniques have been overlooked in one of their most important contexts: agricultural botany. This paper addresses this omission by harnessing unexamined archival material from the National Institute of Agricultural Botany (NIAB), a British plant science organization. During the 1980s the NIAB carried out three overlapping research programmes in crop identification and analysis: electrophoresis, near infrared spectroscopy (NIRS) and machine vision systems. For each of these three programmes, contemporary economic, statutory and scientific factors behind their uptake by the NIAB are discussed. This approach reveals significant links between taxonomic practice at the NIAB and historical questions around agricultural research, intellectual property and scientific values. Such links are of further importance given that the techniques developed by researchers at the NIAB during the 1980s remain part of crop classification guidelines issued by international bodies today.

Model Organisms and Traditional Chinese Medicine Syndrome Models

Traditional Chinese medicine (TCM) is an ancient medical system with a unique cultural background. Nowadays, more and more Western countries due to its therapeutic efficacy are accepting it. However, safety and clear pharmacological action mechanisms of TCM are still uncertain. Due to the potential application of TCM in healthcare, it is necessary to construct a scientific evaluation system with TCM characteristics and benchmark the difference from the standard of Western medicine. Model organisms have played an important role in the understanding of basic biological processes. It is easier to be studied in certain research aspects and to obtain the information of other species. Despite the controversy over suitable syndrome animal model under TCM theoretical guide, it is unquestionable that many model organisms should be used in the studies of TCM modernization, which will bring modern scientific standards into mysterious ancient Chinese medicine. In this review, we aim to summarize the utilization of model organisms in the construction of TCM syndrome model and highlight the relevance of modern medicine with TCM syndrome animal model. It will serve as the foundation for further research of model organisms and for its application in TCM syndrome model. PMID:24381636

Increasing human appropriation of freshwater resources presents a tangible limit to the sustainability of cities, agriculture, and ecosystems in the western United States. Marc Reisner tackles this theme in his 1986 classic Cadillac Desert: The American West and Its Disappearing Water. Reisner's analysis paints a portrait of region-wide hydrologic dysfunction in the western United States, suggesting that the storage capacity of reservoirs will be impaired by sediment infilling, croplands will be rendered infertile by salt, and water scarcity will pit growing desert cities against agribusiness in the face of dwindling water resources. Here we evaluate these claims using the best available data and scientific tools. Our analysis provides strong scientific support for many of Reisner's claims, except the notion that reservoir storage is imminently threatened by sediment. More broadly, we estimate that the equivalent of nearly 76% of streamflow in the Cadillac Desert region is currently appropriated by humans, and this figure could rise to nearly 86% under a doubling of the region's population. Thus, Reisner's incisive journalism led him to the same conclusions as those rendered by copious data, modern scientific tools, and the application of a more genuine scientific method. We close with a prospectus for reclaiming freshwater sustainability in the Cadillac Desert, including a suite of recommendations for reducing region-wide human appropriation of streamflow to a target level of 60%.

The Food Safety Modernization Act: a barrier to trade? Only if the science says so.

McNeill, Naomi

2012-01-01

The Food Safety Modernization Act improves oversight of America's food safety system. Title III, which regulates imported food, may create extra burdens for importers and therefore act as a barrier to trade. What will be on trial before the World Trade Organization (WTO), however, is not the law's content, but the science supporting it. Under the WTO regime, food safety laws that could restrict the free movement of food commodities must be sufficiently justified by scientific evidence. Member states must engage in risk assessments and regulate food imports in a manner that is "no more restrictive than necessary" to protect against the health risks identified by scientific evidence. This article examines the requirements of the WTO to evaluate the FSMA's legality under WTO rules. It analyzes the case law of the WTO Panel and Appellate Body and compares the FMSA to the EU's General Food Law.

The description of ionic currents that flow across the membrane of the squid giant axon during an action potential sparked an interest in determining whether there were similar currents in vertebrates. The preparation of choice was the node of Ranvier in single myelinated fibers in frog. José del Castillo spent 3 years on the United States mainland from 1956 to 1959. During that time, he collaborated with Jerome Y. Lettvin and John W. Moore. I discuss how these individuals met one another and some of their scientific discoveries using the voltage clamp to study squid giant axons and frog nodes. Much of this work was conducted at the Marine Biological Laboratory in Woods Hole, MA, and I attempt to convey a sense of the unique scientific "melting pot" that existed at the Marine Biological Laboratory and the broader effect that del Castillo had on "modern" neuroscience.

In this article, we will discuss some aspects of the construction of the meanings concerning the body from the scientific speech which was modeled based on modern thinking and became the hegemonic thinking of some sectors of the medical field. Meanings attributed to the body bring questions that come from other areas of the social life and those questions will build the aesthetic parameters which will be part of the identity construction, in the relation with the body itself, subjectivity and healthcare. We will describe some moments of the construction of the modern scientific thought and how this thought became hegemonic, influences the common sense, naturalizes identity construction and how dealing with the body, interferes in the healthcare, show a division among some sectors of the biomedicine, reinforce an specific type of medical rationality and makes an epistemic base and principle (theoretical and discursive) to some sectors connected to aesthetic medicine and aesthetic surgeries.

Its affiliated research institute held the principle of "realizing the scientific truth of TCM, training TCM advanced talents", marking the beginning of the pioneering of "scientific TCM". The educational plan, clinical research and academic organization based on "carrying forward the quintessence of Chinese culture, absorbing and digesting the new knowledge" showed a certain influence at home and abroad. The College advocated the combination of communicating with famous physicians and the study of theory, cultivation of students' organization and academic society, launching of journals, and organizing students' research associations was aiming at the satisfaction of the social needs and teaching orientation. Its running experience provided useful reference for modern TCM medical education.

Toward the Inference of Deglacial Ocean Dynamics from the Spatial Pattern of LGM-to-Modern d13C and d18O Change

2014-12-01

Estimates of the whole-ocean d13C change between the Last Glacial Maximum (LGM) and the modern-day are converging to values of about 0.4 per mil, and are of great use in partitioning land versus ocean contributions to the deglacial carbon cycle. To determine which specific oceanic processes are at play, however, knowledge of the spatial pattern of LGM-to-modern d13C and d18O change is critical. Spatial maps have mostly focused on Atlantic d13C, with less progress for d18O and the Pacific and Indian sectors, due to the concentration of sediment-core observations in the Atlantic and the difficulty in making meaningful maps from sparse data. Here, we demonstrate that a state estimation (or data assimilation) method based on recently compiled data and a simple kinematic ocean model simultaneously produces reasonable results for: 1) global maps of d13C and d18O, 2) uncertainty in the estimated properties, and 3) oceanic water-mass geometry. The observations include benthic d13C and d18O data from 493 marine sediment cores that were collected from the scientific literature and NOAA, PANGEA, and Delphi databases. The kinematic model permits each data point to have influence both up- and downstream along a water-mass pathway, typically allowing a larger geographical range than a statistical interpolation method. No assumption regarding the state of the circulation is necessary, and the modern-day circulation need not be assumed to be representative of the LGM. With this method, meridional (or other) sections can be compared between ocean basins. Furthermore, the internally-consistent d18O and d13C maps are used to determine the LGM-to-modern spatial changes that are robust given the uncertainty and sparsity of data. Rather than simply focus on property maps, we suggest that the link between observations and circulation changes (as reflected by the paths that water travels), points the way toward dynamical processes that must be explained. A particular application of our result is the geographic constraint of possible unobserved reservoirs of d13C or radiocarbon and calculation of their potential impact on the global chain of events during the deglaciation.

A need for a code of ethics in science communication?

The modern western civilization and high standard of living are to a large extent the 'fruits' of scientific endeavor over generations. Some examples include the longer life expectancy due to progress in medical sciences, and changes in infrastructure associated with the utilization of electromagnetism. Modern meteorology is not possible without the state-of-the-art digital computers, satellites, remote sensing, and communications. Science also is of relevance for policy making, e.g. the present hot topic of climate change. Climate scientists have recently become much exposed to media focus and mass communications, a task for which many are not trained. Furthermore, science, communication, and politics have different objectives, and do not necessarily mix. Scientists have an obligation to provide unbiased information, and a code of ethics is needed to give a guidance for acceptable and unacceptable conduct. Some examples of questionable conduct in Norway include using the title 'Ph.D' to imply scientific authority when the person never had obtained such an academic degree, or writing biased and one-sided articles in Norwegian encyclopedia that do not reflect the scientific consensus. It is proposed here that a set of guide lines (for the scientists and journalists) and a code of conduct could provide recommendation for regarding how to act in media - similar to a code of conduct with respect to carrying out research - to which everyone could agree, even when disagreeing on specific scientific questions.

The new conversion model MODERN to derive erosion rates from inventories of fallout radionuclides

The measurement of fallout radionuclides (FRNs) has become one of the most commonly used methods to quantify soil erosion and depositional processes. FRNs include anthropogenic radionuclides (e.g. 137Cs, 239+240Pu) released into the atmosphere during nuclear bomb tests and power plant accidents (e.g Chernobyl, Fukushima-Daiichi), as well as natural radiotracers such as 210Pbex and 7Be. FRNs reach the land surface by dry and wet fallouts from the atmosphere. Once deposited, FRNs are tightly adsorbed by fine soil particles and their subsequent redistribution is mostly associated with soil erosion processes. FRNs methods are based on a qualitative comparison: the inventory (total radionuclide activity per unit area) at a given sampling site is compared to that of a so called reference site. The conversion of FRN inventories into soil erosion and deposition rates is done with a variety of models, which suitability is dependent on the selected FRN, soil cultivation (ploughed or unploughed) and movement (erosion or deposition). The authors propose a new conversion model, which can be easily and comprehensively used for different FRNs, land uses and soil redistribution processes. This new model i.e. MODERN (MOdelling Deposition and Erosion rates with RadioNuclides) considers the precise depth distribution of a given FRN at a reference site, and allows adapting it for any specific site conditions. MODERN adaptability and performance has been tested on two published case studies: (i) a 137Cs study in an alpine and unploughed area in the Aosta valley (Italy) and (ii) a 210Pbex study on a ploughed area located in Romania. The results show a good agreement and a significant correlation (r= 0.91, p<0.0001) between the results of MODERN and the published models currently used by the FRN scientific community (i.e. the Profile Distribution Model and the Mass Balance Model). The open access code and the cost free accessibility of MODERN will ensure the promotion of a wider application of FRNs for investigating soil erosion and sedimentation processes.

Fifty years with the Hamilton scales for anxiety and depression. A tribute to Max Hamilton.

PubMed

Bech, P

2009-01-01

From the moment Max Hamilton started his psychiatric education, he considered psychometrics to be a scientific discipline on a par with biochemistry or pharmacology in clinical research. His clinimetric skills were in operation in the 1950s when randomised clinical trials were established as the method for the evaluation of the clinical effects of psychotropic drugs. Inspired by Eysenck, Hamilton took the long route around factor analysis in order to qualify his scales for anxiety (HAM-A) and depression (HAM-D) as scientific tools. From the moment when, 50 years ago, Hamilton published his first placebo-controlled trial with an experimental anti-anxiety drug, he realized the dialectic problem in using the total score on HAM-A as a sufficient statistic for the measurement of outcome. This dialectic problem has been investigated for more than 50 years with different types of factor analyses without success. Using modern psychometric methods, the solution to this problem is a simple matter of reallocating the Hamilton scale items according to the scientific hypothesis under examination. Hamilton's original intention, to measure the global burden of the symptoms experienced by the patients with affective disorders, is in agreement with the DSM-IV and ICD-10 classification systems. Scale reliability and obtainment of valid information from patients and their relatives were the most important clinimetric innovations to be developed by Hamilton. Max Hamilton therefore belongs to the very exclusive family of eminent physicians celebrated by this journal with a tribute. 2009 S. Karger AG, Basel.

Are Allopathic and Holistic Medicine Incommensurable?

PubMed

Evangelatos, Nikolaos; Eliadi, Irini

2016-01-01

The shift from the Aristotelian to the Newtonian scientific paradigm gave birth to progresses in the natural, hard sciences and contributed to the emergence of modernity. Allopathic medicine gradually implemented those progresses, transforming itself into contemporary biomedicine. In the early 20th century, replacement of Newtonian physics by quantum mechanics and Einstein's theory of relativity resulted in a new paradigm shift in the natural, hard sciences. This shift gave birth to post-modern perceptions, which attempt to put those changes in context. Within this new context, holistic therapeutic approaches are considered more compatible with the new paradigm. Different paradigms in the natural, hard sciences are considered to be incommensurable (in the Kuhnian sense). This incommensurability is also transferred to the different societal contexts, the different «Weltanschauungen» that rely on different scientific paradigms. However, drawing on arguments that range from historical and philosophical to practical and sociological ones, we argue that, although based on different scientific paradigms, allopathic and holistic medicine are not incommensurable, but rather complementary. This may be related to the inherent attributes of medicine, a fact that reinforces the debate on its epistemological status. © 2016 S. Karger GmbH, Freiburg.

We have an ethical and scientific obligation to Refine all aspects of the life of the laboratory-housed dog. Across industry there are many differences amongst facilities, home pen design and husbandry, as well as differences in features of the dogs such as strain, sex and scientific protocols. Understanding how these influence welfare, and hence scientific output is therefore critical. A significant proportion of dogs' lives are spent in the home pen and as such, the design can have a considerable impact on welfare. Although best practice guidelines exist, there is a paucity of empirical evidence to support the recommended Refinements and uptake varies across industry. In this study, we examine the effect of modern and traditional home pen design, overall facility design, husbandry, history of regulated procedures, strain and sex on welfare-indicating behaviours and mechanical pressure threshold. Six groups of dogs from two facilities (total n=46) were observed in the home pen and tested for mechanical pressure threshold. Dogs which were housed in a purpose-built modern facility or in a modern design home pen showed the fewest behavioural indicators of negative welfare (such as alert or pacing behaviours) and more indicators of positive welfare (such as resting) compared to those in a traditional home pen design or traditional facility. Welfare indicating behaviours did not vary consistently with strain, but male dogs showed more negative welfare indicating behaviours and had greater variation in these behaviours than females. Our findings showed more positive welfare indicating behaviours in dogs with higher mechanical pressure thresholds. We conclude that factors relating to the design of home pens and implementation of Refinements at the facility level have a significant positive impact on the welfare of laboratory-housed dogs, with a potential concomitant impact on scientific endpoints.

[Drug advertising as communication between the pharmaceutical industry and the physician: advertisements for psychotropic drugs in the Dutch medical journal, Nederlands Tijdschrift voor Geneeskunde, 1900-1940].

In this article we explore the historical development of drug advertisements for psychotropic drugs in the leading Dutch medical journal from 1900 to 1940. The advertisements for hypnotics and sedatives, in The Nederlands Tijdschrift voor Geneeskunde (Dutch medical journal) reflected the changes in the vocabulary and image promoted by the pharmaceutical companies. In the first two decades, the advertisements were sober and to the point, and included the trademark, company name, molecular formula and therapeutic properties of the medication. The emphasis was on creating a scientific image of reliable symptom control for the therapeutic drug. In doing so, the ethical drug companies tried (successfully) to distinguish themselves from the producers of patent medicines. Once scientific credibility was established, the form and content of the advertisements changed significantly. In the late 1920s and 1930s drug companies embraced modern advertising techniques, developing a figurative language to address the changing beliefs and practices of Dutch physicians. Instead of promoting therapeutic drugs as safe and scientific, the emphasis was on their effectiveness in comparison to similar drugs. In the process, scientific information was reduced to an indispensable standardized minimum, whereby therapeutic drugs were advertised according to the latest pharmacological taxonomy rather than molecular formulas. The image-making of 'ethical marketing' began during the interwar years when marketers applied modern advertising techniques and infotainment strategies. The scanty black and white informational bulletins transitioned into colourful advertisements. The pharmaceutical companies employed the same medical language as used by physicians, so that one word or image in an advertisement would suffice for the physician to recognize a drug and its therapeutic properties. These developments show the changing relationship between the modern ethical pharmaceutical industry and Dutch doctors during the interwar years--from rapprochement towards concerted action.

The Scientific Committee on Antarctic Research (SCAR) initiates, develops, and coordinates international scientific research in the Antarctic region. SCAR is assuming a leadership position in the IPY primarily through its five major Scientific Research Programs; ACE, SALE, EBA, AGCS, and ICESTAR; which will be briefly described.Antarctic Climate Evolution (ACE) promotes the exchange of data and ideas between research groups focusing on the evolution of Antarctica's climate system and ice sheet. The program will: (1) quantitatively assess the climate and glacial history of Antarctica; (2) identify the processes which govern Antarctic change and feed back around the globe; (3) improve our ability to model past changes in Antarctica; and (4)document past change to predict future change in Antarctica. Subglacial Antarctic Lake Environments (SALE) promotes, facilitates, and champions cooperation and collaboration in the exploration and study of subglacial environments in Antarctica. SALE intends to understand the complex interplay of biological, geological, chemical, glaciological, and physical processes within subglacial lake environments through coordinated international research teams. Evolution and Biodiversity in the Antarctic (EBA) will use a suite of modern techniques and interdisciplinary approaches, to explore the evolutionary history of selected modern Antarctic biota, examine how modern biological diversity in the Antarctic influences the way present-day ecosystems function, and thereby predict how the biota may respond to future environmental change. Antarctica and the Global Climate System (AGCS) will investigate the nature of the atmospheric and oceanic linkages between the climate of the Antarctic and the rest of the Earth system, and the mechanisms involved therein. A combination of modern instrumented records of atmospheric and oceanic conditions, and the climate signals held within ice cores will be used to understand past and future climate variability and change in the Antarctic as a result of natural and anthropogenic forcings over the last 100,000 years. Interhemispheric Conjugacy Effects in Solar-Terrestrial and Aeronomy Research (ICESTAR) will study the interactions between and collective behavior of the many component parts of the Earth system, including the interaction between the natural environment and human society. Objectives include specification and prediction of the state of the system and assimilation and integration of data from disparate sources to understand the complex geospace environment.

The Notion of Scientific Knowledge in Biology

NASA Astrophysics Data System (ADS)

Morante, Silvia; Rossi, Giancarlo

2016-03-01

The purpose of this work is to reconsider and critically discuss the conceptual foundations of modern biology and bio-sciences in general, and provide an epistemological guideline to help framing the teaching of these disciplines and enhancing the quality of their presentation in High School, Master and Ph.D. courses. After discussing the methodological problems that arise in trying to construct a sensible and useful scientific approach applicable to the study of living systems, we illustrate what are the general requirements that a workable scheme of investigation should meet to comply with the principles of the Galilean method. The amazing success of basic physics, the Galilean science of election, can be traced back to the development of a radically " reductionistic" approach in the interpretation of experiments and a systematic procedure tailored on the paradigm of " falsifiability" aimed at consistently incorporating new information into extended models/theories. The development of bio-sciences seems to fit with neither reductionism (the deeper is the level of description of a biological phenomenon the more difficult looks finding general and simple laws), nor falsifiability (not always experiments provide a yes-or-no answer). Should we conclude that biology is not a science in the Galilean sense? We want to show that this is not so. Rather in the study of living systems, the novel interpretative paradigm of " complexity" has been developed that, without ever conflicting with the basic principles of physics, allows organizing ideas, conceiving new models and understanding the puzzling lack of reproducibility that seems to affect experiments in biology and in other modern areas of investigation. In the delicate task of conveying scientific concepts and principles to students as well as in popularising bio-sciences to a wider audience, it is of the utmost importance for the success of the process of learning to highlight the internal logical consistency of biology and its compliance with the fundamental laws of physics.

Modern nature and climate changes in Siberia: new methods and results of analysis of instrumented observations

Kabanov, Mikhail V.

2002-02-01

Peculiarity of nature and climate changes in middle latitudes of the Northern Hemisphere and in Siberia is that the temporal variability of meteorological quantities here has a wide range and their spatial variability has a complicated zone structure. Therefore, regional monitoring of modern nature and climate changes in Siberia is of scientific interest from the viewpoint of the global changes observed. Another Siberian peculiarity is associated with the fact that there are many unique objects that have global importance both as natural complexes (boreal forests, water- bog systems, Baikal lake, etc.) And as technogenic objects (oil and gas production, coal mining, metallurgy, transport, etc.). Therefore monitoring and modeling of regional nature and climate changes in Siberia have great practical importance, which is underestimated now, for industrial development of Siberia. Taking into account the above peculiarities and tendencies on investigation of global and regional environmental and climate changes, the multidisciplinary project on Climate and Ecological Monitoring of Siberia (CEMS) was accepted to the research and development program Sibir' since 1993. To realize this project, the Climate and Ecological Observatory was established in Tomsk at the Institute for Optical Monitoring (IOM) SB RAS. At the present time the stations (the basic and background ones) of this observatory are in a progress and theory and instruments for monitoring are being developed as well. In this paper we discuss some results obtained in the framework of CEMS project that were partially published in the monographs, in scientific journals, and will be published in the Proceedings of the 8th Joint International Symposium on Atmospheric and Ocean Optics and Atmosphere Physics. This review has a purpose not only to discuss the obtained regularities but also to formulate scientific and technical tasks for further investigations into the regional changes of technogenic, natural, and climate systems.

Reproducibility verification is essential to the practice of the scientific method. Researchers report their findings, which are strengthened as other independent groups in the scientific community share similar outcomes. In the many scientific fields where software has become a fundamental tool for capturing and analyzing data, this requirement of reproducibility implies that reliable and comprehensive software platforms and tools should be made available to the scientific community. The tools will empower them and the public to verify, through practice, the reproducibility of observations that are reported in the scientific literature. Medical image analysis is one of the fields in which the use of computational resources, both software and hardware, are an essential platform for performing experimental work. In this arena, the introduction of the Insight Toolkit (ITK) in 1999 has transformed the field and facilitates its progress by accelerating the rate at which algorithmic implementations are developed, tested, disseminated and improved. By building on the efficiency and quality of open source methodologies, ITK has provided the medical image community with an effective platform on which to build a daily workflow that incorporates the true scientific practices of reproducibility verification. This article describes the multiple tools, methodologies, and practices that the ITK community has adopted, refined, and followed during the past decade, in order to become one of the research communities with the most modern reproducibility verification infrastructure. For example, 207 contributors have created over 2400 unit tests that provide over 84% code line test coverage. The Insight Journal, an open publication journal associated with the toolkit, has seen over 360,000 publication downloads. The median normalized closeness centrality, a measure of knowledge flow, resulting from the distributed peer code review system was high, 0.46. PMID:24600387

Single-target drugs have not achieved satisfactory therapeutic effects for complex diseases involving multiple factors. Instead, innovations in recent drug research and development have revealed the emergence of compound drugs, such as cocktail therapies and “polypills”, as the frontier in new drug development. A traditional Chinese medicine (TCM) prescription that is usually composed of several medicinal herbs can serve a typical representative of compound medicines. Although the traditional compatibility theory of TCM cannot be well expressed using modern scientific language nowadays, the fundamental purpose of TCM compatibility can be understood as promoting efficacy and reducing toxicity. This paper introduces the theory and methods of efficacy-oriented compatibility for developing component-based Chinese medicines. PMID:25864650

Fluorescence confocal microscopy represents one of the central tools in modern sciences. Correspondingly, a growing amount of research relies on the development of novel microscopic methods. During the last decade numerous microscopic approaches were developed for the investigation of various scientific questions. Thereby, the former qualitative imaging methods became replaced by advanced quantitative methods to gain more and more information from a given sample. However, modern microscope systems being as complex as they are, require very precise and appropriate calibration routines, in particular when quantitative measurements should be compared over longer time scales or between different setups. Multispectral beads with sub-resolution size are often used to describe the point spread function and thus the optical properties of the microscope. More recently, a fluorescent layer was utilized to describe the axial profile for each pixel, which allows a spatially resolved characterization. However, fabrication of a thin fluorescent layer with matching refractive index is technically not solved yet. Therefore, we propose a novel type of calibration concept for sectioned image property (SIP) measurements which is based on fluorescent solution and makes the calibration concept available for a broader number of users. Compared to the previous approach, additional information can be obtained by application of this extended SIP chart approach, including penetration depth, detected number of photons, and illumination profile shape. Furthermore, due to the fit of the complete profile, our method is less susceptible to noise. Generally, the extended SIP approach represents a simple and highly reproducible method, allowing setup independent calibration and alignment procedures, which is mandatory for advanced quantitative microscopy.

Sheet erosion is one of the major threats to alpine soils. To quantify its role and impact in the degradation processes of alpine grasslands, the application of Fallout Radionuclides (FRN) showed very promising results. The specific characteristics of plutonium 239 + 240 ( 239+240 Pu), such as the homogeneous fallout distribution, the long half-life and the cost and time effective measurements make this tracer application for investigating soil degradation in Alpine grasslands more suitable than any other FRN (e.g. 137 Cs). However, the conversion of 239+240 Pu inventories into soil erosion rates remains a challenge. Currently available conversion models have been developed mainly for 137 Cs with later adaptation to other FRN (e.g. Excess 210 Pb, and 7 Be), each model being defined for specific land use (ploughed and/or unploughed) and processes (erosion or deposition). As such, they may fail in describing correctly the distribution of Pu isotopes in the soil. A new conversion model, MODERN, with an adaptable algorithm to estimate erosion and deposition rates from any FRN inventory changes was recently proposed (Arata et al., 2016). In this complementary contribution, the authors compare the application of MODERN to other available conversion models. The results show a good agreement between soil redistribution rates obtained from MODERN and from the models currently used by the FRN scientific community (i.e. the Inventory Method).

Purpose of the study the analysis of the monitoring of fine particulate matters in the atmospheric air of Saint-Petersburg and identification of the main problems of the monitoring. Research methods methods of scientific hypothetical deductive cognition, sanitary-statistical methods, general logical methods and approaches of researches: analysis, synthesis, abstracting, generalization, induction. Results. The article represents the analysis of the monitoring of fine particulate matters in the atmospheric air of Saint- Petersburg. Only 11 in automatic monitoring stations out of 22 there is carried out the control of fine particulate matters: in 7 - PM and PM, and in 4 - PM The average year concentrations were below MAC in all the stations. The maximum concentrations achieved 3 MAC, but the repeatance of cases of exceedence of concentrations more than MAC was very rare. On the average of the city concentrations of PM were decreased from 0,8 MAC in 2006 and 1,1 MAC in 2007 to 0,5 MAC in 2013-14. The executed analysis revealed main problems of the monitoring of fine particulate matters in the Russian Federation. They include the absence of the usage 1of the officially approved methods of controlling of PM and PM in the atmospheric air until March 1, 2016, lack of the modern equipment for measurement of fine particulate matters. Conclusions. Therefore, the state of the monitoring of fine particulate matters in the atmospheric air in the Russian Federation fails to be satisfactory. It is necessary to improve system of the monitoring, create modern Russian appliances, methods and means for measurement of fine particulate matters concentrations in the atmospheric air.

The paper is aimed at detecting conceptual conflicts within the architectural and urban construction activity (AUCA), defining their reasons and substantiating ways to decrease adverse effects they caused. Methods of causes and effects analyses are used, as well as evolutional and comparative analyses. They allow defining the laws to form activity model in modern environment, whose elements are ranked. Relevance of the paper is based on defining scientific and theoretical grounds of necessity to improve methodology of AUCA via its adaption to the imperatives of state management. System analyses enabled to prove practicability of considering factors of institution environment for reorganization of the model of AUCA, which provide the fullest implementation of sustainable development principles. It was proved that territorial planning is not only the leading type of AUCA, but also integrator for functioning structures of state management within planning of social and economic development. As main result of the paper consist in detection of the perspective ways for evolution of modern methodology due to increasing interdisciplinary aspect leading to the qualitative renewal of territorial management principles.

Curiosity, forbidden knowledge, and the reformation of natural philosophy in early modern England.

PubMed

Harrison, P

2001-06-01

From the patristic period to the beginning of the seventeenth century curiosity was regarded as an intellectual vice. Curious individuals were considered to be proud and "puffed up," and the objects of their investigations were deemed illicit, dispute engendering, unknowable, or useless. Seventeenth-century projects for the advancement of learning had to distance themselves from curiosity and its dubious fruits or, alternatively, enhance the moral status of the curious sensibility. Francis Bacon's proposals for the instauration of knowledge were an integral part of a process by which curiosity underwent a remarkable transformation from vice to virtue over the course of the seventeenth century. The changing fortunes of this human propensity highlight the morally charged nature of early modern debates over the status of natural philosophy and the particular virtues required of its practitioners. The rehabilitation of curiosity was a crucial element in the objectification of scientific knowledge and led to a gradual shift of focus away from the moral qualities of investigators and the propriety of particular objects of knowledge to specific procedures and methods.

Sciences from below: feminisms, postcolonialities, and modernities.

Weaver, Harlan

2010-01-01

Sandra Harding's newest book, Sciences from Below: Feminisms, Postcolonialities, and Modernities, continues her work in feminist standpoint theory and science and technologies studies, asking how we might judge "good" science. Attentive to race, class, gender, and imperialism, Harding critically examines Northern and Southern sciences and technologies by adopting the perspective of those who see from below. This vision from the peripheries lets Harding question stories of modern scientific progress, revealing a multiplicity of "ethnosciences" and critiquing modernity itself. However, while Harding aims to produce knowledge for the North's others by emphasizing woman's experience, she fails to question the category "woman," ignoring contemporary transgender and queer scholarship. Further, it is Harding's care for the North's subjugated others that motivates her writing, revealing that the struggle to achieve the standpoint "from below" so critical to her project is fueled by what her ally Maria Puig de la Bellacasa would term not thinking from, but thinking with, or, more precisely, "thinking with care."

Origins of the historiography of modern Greek science.

Patiniotis, Manolis

2008-01-01

The purpose of the paper is to examine how Greek historians account for the presence of modern scientific ideas in the intellectual environment of eighteenth-century Greek-speaking society. It will also discuss the function of the history of modern Greek science in the context of Greek national historiography. As will be shown, the history of modem Greek science spent most of its life under the shadow of the history of ideas. Despite its seemingly secondary role, however, it occupied a distinctive place within national historiography because it formed the ground upon which different perceptions of the country's European identity converged. In this respect, one of the main goals of this paper is to outline the particular ideological presumptions, which shaped the historiography of modern Greek science under different historical circumstances. At the end an attempt will be made to articulate a viewpoint more in tandem with the recent methodological developments in the history of science.

The questions related to quality classification of animal oocytes are explored by numerous scientific and research centres. This research is important, particularly in the context of improving the breeding value of farm animals. The methods leading to the stimulation of normal development of a larger number of fertilised animal oocytes in extracorporeal conditions are of special importance. Growing interest in the techniques of supported reproduction resulted in searching for new, increasingly effective methods for quality assessment of mammalian gametes and embryos. Progress in the production of in vitro animal embryos in fact depends on proper classification of obtained oocytes. The aim of this paper was the development of an original method for quality assessment of oocytes, performed on the basis of their graphical presentation in the form of microscopic digital images. The classification process was implemented on the basis of the information coded in the form of microphotographic pictures of the oocytes of domestic pig, using the modern methods of neural image analysis.

The modern markets are characterized by fierce competition, constantly changing demand, increasing demands of consumers, shortening of the life cycle of goods and services in connection with scientific and technological progress. Therefore, for survival, modern logistic systems of industrial enterprises must be constantly improved. Modern economic literature is represented by a large volume of publications on various aspects of the studied issues. They consider the issues of project management in the logistics system that inevitably encounter with triple Limited. It initially describes the balance between project content, cost, and time. Later it was suggested to either replace the content with quality or add a fourth criterion. Therefore it is possible to name such limitation as triple or four-criteria limitation.

This article examines research on hypnosis and suggestion, starting with the nineteenth-century model proposed by Enrico Morselli (1852-1929), an illustrious Italian psychiatrist and psychologist. The authors conducted an original psychophysiological analysis of hypnosis, distancing the work from the neuropathological concept of the time and proposing a model based on a naturalistic approach to investigating mental processes. The issues investigated by Morselli, including the definition of hypnosis and analysis of specific mental processes such as attention and memory, are reviewed in light of modern research. From the view of modern neuroscientific concepts, some problems that originated in the nineteenth century still appear to be present and pose still-open questions.

[John Snow, the cholera epidemic and the foundation of modern epidemiology].

John Snow (1813-1858) was a brilliant British physician. Since young he stood out for his acute observation capacity, logical thinking and perseverance, first in anesthetics and later in epidemiology. The successive outbreaks of cholera that affected London, motivated him to study this disease from a populational point of view. He related the appearance of cases to the consumption of "morbid matter", responsible for the acute diarrhea with dehydration that characterizes this disease. Bravely, Snow opposed to certain theories present at his time, sacrificing his own prestige. He was a pioneer in the use of modern epidemiological investigation methodologies such as conducting surveys and spatial epidemiology. Fairly, he is considered nowadays as father of modern epidemiology by the scientific community.

Russian legislation lags behind the rapid developments witnessed in genetic engineering. Only a scientifically based and well-substantiated policy on the place of organisms that are created with the use of genetic engineering technologies and an assessment of the risks associated with them could guarantee that the breakthroughs achieved in modern genetic engineering technologies are effectively put to use in the real economy. A lack of demand for such breakthroughs in the practical field will lead to stagnation in scientific research and to a loss of expertise.

The GMO case in France: politics, lawlessness and postmodernism.

Kuntz, Marcel

2014-07-03

The GMO debacle in France is analyzed in the light of the balance of forces around this controversy, the changes in position of governments and the opponents' strategic use of intimidation. These factors have caused insurmountable difficulties for scientific experimentations and assessment of the technology, as well as for farmers attempting to grow GM maize in this country. The change from a "modern" to a "postmodern" framing of official public debates and scientific institutions has not appeased confrontations concerning GMOs.

Goethe's anxieties, depressive episodes and (self-)therapeutic strategies: a contribution to method integration in psychotherapy.

PubMed

Holm-Hadulla, Rainer M

2013-01-01

In psychiatry and psychotherapy, abstract scientific principles need to be exemplified by narrative case reports to gain practical precision. Goethe was one of the most creative writers, productive scientists, and effective statesmen that ever lived. His descriptions of feelings, emotions, and mental states related to anxieties, depressive episodes, dysthymia, and creativity are unique in their phenomenological precision and richness. His life and work can thus serve as an excellent example enhancing our understanding of the relationship between anxiety, depression and creativity. Furthermore, he described (self-)therapeutic strategies that reinforce and refine modern views. Goethe's self-assessments in his works and letters, and the descriptions by others are analyzed under the perspective of current psychiatric classification. His therapeutic techniques and recommendations are compared with cognitive-behavioral, psychodynamic, and existential psychotherapy to amplify modern concepts of psychotherapy. From a scientific perspective, several distinctive depressive episodes can be diagnosed in Goethe's life. They were characterized by extended depressive moods, lack of drive, and loss of interest and self-esteem combined with social retreat. Goethe displayed diffuse and phobic anxieties as well as dysthymia. His (self-)therapeutic strategies were: (a) the systematic use of helping alliances, (b) behavioral techniques, (c) cognitive reflection on meanings and beliefs, (d) psychodynamic and psychoanalytic remembering, repeating, and working through, and (e) existential striving for self-actualization, social commitment, meaning, and creativity. In Goethe's life, creative incubation, illumination, and elaboration appear to have been associated with psychic instability and dysthymia, sometimes with depressive episodes in a clinical sense. On the one hand, his creative work was triggered by anxieties, dysthymia, and depressive moods. On the other hand, his creativity helped him to cope with psychic disorders and suicidal tendencies. Furthermore, Goethe described psychotherapeutic strategies that resemble modern techniques. He integrated relational, behavioral, cognitive, psychodynamic, and existential techniques and attitudes. These modern psychotherapeutic approaches can be exemplified and enhanced by reflecting upon the (self-)therapeutic efforts of one of the most creative persons that have ever lived. Hermeneutics as the art of communication and understanding derived from Goethe's (self-)therapy and creative works can serve as a meta-theoretical framework for the integration of different psychotherapeutic approaches.

PubMed Central

DEHDARI, Sahar; HAJIMEHDIPOOR, Homa

2018-01-01

Background: Adiantum capillus-veneris Linn (Maidenhair fern) is an herb belonging to the family Pteridaceae. It is named as “Pare-siavashan” in medical and pharmaceutical textbooks of Iranian Traditional Medicine. The fronds of Maidenhair fern were mainly administrated by ancient physicians as single medicine or in combination with other plants in multi-herbal formulations for curing different diseases. Because of different chemical compositions, the herb fronds were also assessed for its numerous pharmacological effects. Therefore, the current study was done to review the traditional usage and modern pharmacological and toxicological effects of Maidenhair fern. Methods: Scientific databases and publications including Web of Science, PubMed, Scopus, Science direct, Cochrane Library, SID (for Persian papers) and medical and pharmaceutical textbooks of traditional medicine as well were searched for “Adiantum capillus-veneris”, “Maidenhair fern” and “Pare-siavashan” without limitation up to 2016. Results: Maidenhair fern exhibited to possess anti-diabetic, anticonvulsant, analgesic, hypocholesterolemic, goitrogenic, anti-thyroidal, antibacterial, antifungal, wound healing, antiobesity, anti hair loss, anti-asthmatic, anti-inflammatory, antidiarrheal and antispasmodic, antioxidant as well as diuretic, anti-urolithiatic and detoxifying effects in modern medicine. Ancient physicians declared some of the confirmed pharmacological effects. Conclusion: Maidenhair fern frond can be a good candidate for clinical purpose. Therefore, future researches on the other mentioned effects in traditional medicine are recommended. PMID:29445628

The current article positions the combined burn and non-burn injuries in the general array of civilian and combat burns. For that purpose the official state statistics and scientific medical publications, domestic as well as foreign, have been analyzed. It has been shown that in peace time the combined burn/trauma injuries are infrequent. But the same type of injury becomes routine especially among the civilian population in the conditions of the modern so called "hybrid war". And the medical service should be prepared for it.

Cosmology is the attempt to understand in scientific terms the structure and evolution of the universe as a whole. This ambition has been with us since the ancient Greeks, even if the developments in modern cosmology have provided a picture of the universe dramatically different from that of Pythagoras, Plato and Aristotle. The cosmological thinking of these figures, e.g. the belief in uniform circular motion of the heavens, was closely related to their philosophical ideas, and it shaped the field of cosmology at least up to the times of Copernicus and Kepler.

[Theory of toxic classification of traditional Chinese medicine and recommendations for revision of China pharmacopeia (volume 1)].

Toxic classification of traditional Chinese medicine, as a contribution of traditional Chinese medicine (TCM) to the recognition of medicinal toxicity and rational use of medicinal materials by Chinese people, is now a great issue related to safe medication, sustainable development and internationalization of Chinese medicine. In this article, the origination and development of toxic classification theory was summarized and analyzed. Because toxic classification is an urgent issue related to TCM industrialization, modernization and internationalization, this article made a systematic analysis on the nature and connotation of toxic classification as well as risk control for TCM industry due to the medicinal toxicity. Based on the toxic studies, this article made some recommendations on toxic classification of Chinese medicinal materials for the revision of China Pharmacopeia (volume 1). From the aspect of scientific research, a new technical guideline for research on toxic classification of Chinese medicine should be formulated based on new biological toxicity test technology such as Microtox and ADME/Tox, because the present classification of acute toxicity of mice/rats can not met the modern development of Chinese medicine any more. The evaluation system and technical SOP of TCM toxic classification should also be established, and they should well balance TCM features, superiority and international requirements. From the aspect of medicine management, list of toxic medicines and their risk classification should be further improved by competent government according to scientific research. In China Pharmacopeia (volume I), such descriptions of strong toxicity, toxicity or mild toxicity should be abandoned when describing medicine nature and flavor. This revision might help promote TCM sustainable development and internationalization, and enhance the competitive capacity of Chinese medicine in both domestic and international market. However, description of strong toxicity, toxicity or mild toxicity might be used when making cautions for the medicine, stating that the description is based on Chinese classic works. In this way, TCM traditional theory might be inherited and features of Chinese medicine maintained and reflected. Besides, modern findings should be added to the cautions, including dose-response relationship, toxic mechanism, and toxic elements. The traditional toxic descriptions and modern findings, as a whole, can make the caution clear and scientific, and then promote safe medication and TCM modernization and internationalization.

Tall guys and fat ladies: Grimaldi's Upper Paleolithic burials and figurines in an historical perspective.

Formicola, Vincenzo; Holt, Brigitte

2015-07-20

The importance of the Grimaldi complex of caves and rock shelters is twofold: scientific and historical. Scientifically, it is one of the major Upper Paleolithic sites, considering the variety of mobiliary and parietal art, the number of single and multiple burials and associated grave goods, and the abundant lithic and fauna remains. Historically, the documentation of activity that took place in this site starting from the second half of the 19 th century and the studies carried out on the materials that have been recovered in the decades between 1870s-1910s, provide instructive examples of methods and goals of Paleolithic archeology and anthropology of the epoch. This paper combines the scientific and the historic interest of the site through a chronicle of the events that took place during the period of the most sensational discoveries, i.e. beginning with the identification in 1872 of the first Upper Paleolithic burial and ending with the results of the excavations carried out in 1901 at Grotte des Enfants published in four volumes a few years later. The paper discusses early interpretations and modern views on the different findings and documents changes in perspectives and goals of paleoanthropological research in over a century, raising some of the major issues of contemporary Upper Paleolithic studies.

Absorption and metabolization of sex hormones and their transformation into contraceptive technologies: the paths taken by medical thought in Brazil.

The article analyses knowledge assimilation and the development of clinical and research practices relating to sex hormones among Brazilian gynaecologists. It discusses the paths taken by medical thought from the reception of the hormones to their transformation into contraceptives. Our objective is to comprehend styles of introducing and disseminating medical technologies in the area of reproductive health in Brazil. It uses methods of historical analysis and takes as its source the Anais Brasileiros de Ginecologia, a journal published between 1936 and 1970. From the outset, the accompaniment of scientific breakthroughs in relation to sex hormones and their use to treat diverse female illnesses played a key role in the rapid medical acceptance of hormonal contraception. Scientific and technical questions (side effects, dosages) and the demographic issue formed part of the majority of the debates. Objections from the Catholic Church were considered but did not set the agenda of medical thought on contraceptives. The quest to consolidate gynaecology as a scientific, modern and cosmopolitan area of expertise, along with sanitary and demographic motives that allowed contraceptives to be classed as ethical drugs, are identified as processes underlying the assimilation and metabolization of sex hormones as hormonal contraceptives.

Article-level assessment of influence and translation in biomedical research.

Given the vast scale of the modern scientific enterprise, it can be difficult for scientists to make judgments about the work of others through careful analysis of the entirety of the relevant literature. This has led to a reliance on metrics that are mathematically flawed and insufficiently diverse to account for the variety of ways in which investigators contribute to scientific progress. An urgent, critical first step in solving this problem is replacing the Journal Impact Factor with an article-level alternative. The Relative Citation Ratio (RCR), a metric that was designed to serve in that capacity, measures the influence of each publication on its respective area of research. RCR can serve as one component of a multifaceted metric that provides an effective data-driven supplement to expert opinion. Developing validated methods that quantify scientific progress can help to optimize the management of research investments and accelerate the acquisition of knowledge that improves human health. © 2017 Santangelo.

Comparison of the conceptualization of wisdom in ancient Indian literature with modern views: focus on the Bhagavad Gita.

PubMed

Jeste, Dilip V; Vahia, Ipsit V

2008-01-01

The study of wisdom has recently become a subject of growing scientific interest, although the concept of wisdom is ancient. This article focuses on conceptualization of wisdom in the Bhagavad Gita, arguably the most influential of all ancient Hindu philosophical/religious texts. Our review, using mixed qualitative/quantitative methodology with the help of Textalyser and NVivo software, found the following components to be associated with the concept of wisdom in the Gita: Knowledge of life, Emotional Regulation, Control over Desires, Decisiveness, Love of God, Duty and Work, Self-Contentedness, Compassion/Sacrifice, Insight/Humility, and Yoga (Integration of Personality). A comparison of the conceptualization of wisdom in the Gita with that in modern scientific literature shows several similarities, such as rich knowledge about life, emotional regulation, insight, and a focus on common good (compassion). Apparent differences include an emphasis on control over desires and renunciation of materialistic pleasures. Importantly, the Gita suggests that at least certain components of wisdom can be taught and learned. We believe that the concepts of wisdom in the Gita are relevant to modern psychiatry in helping develop psychotherapeutic interventions that could be more individualistic and more holistic than those commonly practiced today, and they aim at improving personal well-being rather than just psychiatric symptoms.

Modernization of the NASA scientific and technical information program

The NASA Scientific and Technical Information Program utilizes a technology infrastructure assembled in the mid 1960s to late 1970s to process and disseminate its information products. When this infrastructure was developed it placed NASA as a leader in processing STI. The retrieval engine for the STI database was the first of its kind and was used as the basis for developing commercial, other U.S., and foreign government agency retrieval systems. Due to the combination of changes in user requirements and the tremendous increase in technological capabilities readily available in the marketplace, this infrastructure is no longer the most cost-effective or efficient methodology available. Consequently, the NASA STI Program is pursuing a modernization effort that applies new technology to current processes to provide near-term benefits to the user. In conjunction with this activity, we are developing a long-term modernization strategy designed to transition the Program to a multimedia, global 'library without walls.' Critical pieces of the long-term strategy include streamlining access to sources of STI by using advances in computer networking and graphical user interfaces; creating and disseminating technical information in various electronic media including optical disks, video, and full text; and establishing a Technology Focus Group to maintain a current awareness of emerging technology and to plan for the future.

The Second International Workshop 'SANS-YuMO User Meeting at the Start-up of Scientific Experiments on the IBR-2M Reactor', devoted to the 75th anniversary of the birth of Professor Yu M Ostanevich (1936-1992), an outstanding neutron physicist and the founder of small-angle neutron scattering (field, group, and instrument) at JINR FLNPh, was held on 27-30 May at the Frank Laboratory of Neutron Physics. The first Workshop was held in October 2006. Research groups from different neutron centers, universities and research institutes across Europe presented more than 35 oral and poster presentations describing scientific and methodological results. Most of them were obtained with the help of the YuMO instrument before the IBR-2 shutdown in 2006. For the last four years the IBR-2 reactor has been shut down for refurbishment. At the end of 2010 the physical launch of the IBR-2M reactor was finally realized. Nowadays the small-angle neutron scattering (SANS) technique is applied to a wide range of scientific problems in condensed matter, soft condensed matter, biology and nanotechnology, and despite the fact that there are currently over 30 SANS instruments in operation worldwide at both reactor and spallation sources, the demand for beam-time is considerably higher than the time available. It must be remembered, however, that as the first SANS machine on a steady-state reactor was constructed at the Institute Laue Langevin, Grenoble, the first SANS instrument on a 'white' neutron pulsed beam was accomplished at the Joint Institute for Nuclear Research at the IBR-30 reactor, beamline N5. During the meeting Yu M Ostanevich's determinative and crucial contribution to the construction of spectrometers at the IBR-2 high-pulsed reactor was presented, as well as his contribution to the development of the time-of-flight (TOF) small-angle scattering technique, and a selection of other scientific areas. His leadership and outstanding scientific achievements in applications of the Mossbauer effect in physics and chemistry, in SANS studies of polyelectrolytes, small molecules, fractals, metallic glasses, macromolecules, polymers, etc., were recognized by a number of awards including the State Prize of the Russian Federation in 2000. The scientific program of the workshop focused on fundamental and methodical research at the YuMO spectrometer and developments of the SANS instrument at the modernized IBR-2M reactor. We recall that the acronym YuMO of the small-angle neutron scattering spectrometer (MURN), was given in honor of Yu M Ostanevich. One of the most important objectives of this user meeting was to discuss the further development possibilities of the YuMO spectrometer with experts, in the frame of a SANS YuMO Round Table, taking into account the specific performance of the modernized YuMO SANS instrument, and the scientific and technical requests of the instrument's users. Highlights on modern achievements in nanoscience, polymers and biology were other significant goals of the meeting. The plenary invited talks were presented by leading scientists in small-angle neutron scattering and soft condensed matter, including members of the Russian Academy of Sciences: Prof. Heinrich Stuhrmann, Prof. Alexei Khokhlov, Prof. Jose Teixeira, Prof. Alexander Ozerin, Prof. Albrecht Wiedenmann, etc. There were 27 oral talks given and 32 posters presented by 92 participants from 12 countries: Czech Republic, Egypt, France, Germany, Hungary, Moldova, Mongolia, Poland, Romania, Russian Federation, Slovak Republic, and Ukraine. The workshop was organized with the financial support of the Frank Laboratory of Neutron Physics (Joint Institute for Nuclear Research), Horia Hulubei National Institute of Physics and Nuclear Engineering - IFIN HH (Romania), Institute of Macromolecular Chemistry AS CR (Czech Republic), and Comenius University (Slovakia).

Science Awareness and Science Literacy through the Basic Physics Course: Physics with a bit of Metaphysics?

NASA Astrophysics Data System (ADS)

Rusli, Aloysius

2016-08-01

Until the 1980s, it is well known and practiced in Indonesian Basic Physics courses, to present physics by its effective technicalities: The ideally elastic spring, the pulley and moving blocks, the thermodynamics of ideal engine models, theoretical electrostatics and electrodynamics with model capacitors and inductors, wave behavior and its various superpositions, and hopefully closed with a modern physics description. A different approach was then also experimented with, using the Hobson and Moore texts, stressing the alternative aim of fostering awareness, not just mastery, of science and the scientific method. This is hypothesized to be more in line with the changed attitude of the so-called Millenials cohort who are less attentive if not interested, and are more used to multi-tasking which suits their shorter span of attention. The upside is increased awareness of science and the scientific method. The downside is that they are getting less experience of the scientific method which intensely bases itself on critical observation, analytic thinking to set up conclusions or hypotheses, and checking consistency of the hypotheses with measured data. Another aspect is recognition that the human person encompasses both the reasoning capacity and the mental- spiritual-cultural capacity. This is considered essential, as the world grows even smaller due to increased communication capacity, causing strong interactions, nonlinear effects, and showing that value systems become more challenging and challenged due to physics / science and its cosmology, which is successfully based on the scientific method. So students should be made aware of the common basis of these two capacities: the assumptions, the reasoning capacity and the consistency assumption. This shows that the limits of science are their set of basic quantifiable assumptions, and the limits of the mental-spiritual-cultural aspects of life are their set of basic metaphysical (non-quantifiable) assumptions. The bridging between these two human aspects of life, can lead to a “why” of science, and a “meaning” of life. A progress report on these efforts is presented, essentially being of the results indicated by an extended format of the usual weekly reporting used previously in Basic Physics lectures.

The norm and the text: Denzin and Lincoln's handbooks of qualitative method.

PubMed

Fielding, N G

1999-09-01

Qualitative methods have lately enjoyed enhanced legitimacy and are increasingly used in academic and applied social research. Yet the field is marked by controversy about virtually every key tenet of qualitative inquiry, from matters of epistemology to purely practical matters of relations with research subjects. Not only is the practice of qualitative research hotly contested, consensus is lacking about the purpose of qualitative research and whether it has a distinctive role to play relative to other approaches to the study of social phenomena. Against this context, the handbooks of qualitative method edited by Norman Denzin and Yvonna Lincoln represent a significant attempt to capture the breadth of contemporary approaches to qualitative method. The article examines key contributions from the handbooks, drawing on these to develop a view of qualitative method from a pragmatic, realist perspective. Among the issues considered are the significance of relativism, subjectivity, post-modernism and feminist method, the politicization of the purposes of qualitative research, the debate over criteria of validity, and the move to treat qualitative research as an entertainment rather than a scientific practice.

In the modern physics unit included in the course curriculum of grade 10 physics introduced in the 2007-2008 education year, the aim is that students at this grade level are aware of any developments which constitute modern physics and may be considered new, and interpret whether mass, length and time values of the motions at any velocities close to the speed of light vary or not. One of the scientific concepts and subjects among the final ones to be learned in the unit of modern physics with 12 course hours includes the special relativity theorem and its results. The special relativity theorem, the foundation of which was laid by Einstein in 1905, has three significant predictions proven by experiments and observations: time extension, dimensional shortening and mass relativity. At the first stage of this study, a simple and fast solution that uses the Pythagorean relation for problems and must be treated by using the mathematical expressions of the predictions as specified above is given, and this way of solution was taught while the relativity subject was explained to the secondary education students who are fifteen years old from grade 10 in the 2013-2014 education year. At the second stage of the study, a qualitative study is released together with grade 11 students who are sixteen years old in 2014-2015, who learnt to solve any problems in both methods, while the special relativity subject is discussed in the physics course in grade 10. The findings of the study show that the students have a misconception on the relativity theorem and prefer to solve any relativity-related problems by using the Pythagorean method constituting the first stage of this study.

Why are modern scientists so dull? How science selects for perseverance and sociability at the expense of intelligence and creativity.

PubMed

Charlton, Bruce G

2009-03-01

why are so many leading modern scientists so dull and lacking in scientific ambition? because the science selection process ruthlessly weeds-out interesting and imaginative people. At each level in education, training and career progression there is a tendency to exclude smart and creative people by preferring Conscientious and Agreeable people. The progressive lengthening of scientific training and the reduced independence of career scientists have tended to deter vocational 'revolutionary' scientists in favour of industrious and socially adept individuals better suited to incremental 'normal' science. High general intelligence (IQ) is required for revolutionary science. But educational attainment depends on a combination of intelligence and the personality trait of Conscientiousness; and these attributes do not correlate closely. Therefore elite scientific institutions seeking potential revolutionary scientists need to use IQ tests as well as examination results to pick-out high IQ 'under-achievers'. As well as high IQ, revolutionary science requires high creativity. Creativity is probably associated with moderately high levels of Eysenck's personality trait of 'Psychoticism'. Psychoticism combines qualities such as selfishness, independence from group norms, impulsivity and sensation-seeking; with a style of cognition that involves fluent, associative and rapid production of many ideas. But modern science selects for high Conscientiousness and high Agreeableness; therefore it enforces low Psychoticism and low creativity. Yet my counter-proposal to select elite revolutionary scientists on the basis of high IQ and moderately high Psychoticism may sound like a recipe for disaster, since resembles a formula for choosing gifted charlatans and confidence tricksters. A further vital ingredient is therefore necessary: devotion to the transcendental value of Truth. Elite revolutionary science should therefore be a place that welcomes brilliant, impulsive, inspired, antisocial oddballs - so long as they are also dedicated truth-seekers.

Natural products in modern life science.

With a realistic threat against biodiversity in rain forests and in the sea, a sustainable use of natural products is becoming more and more important. Basic research directed against different organisms in Nature could reveal unexpected insights into fundamental biological mechanisms but also new pharmaceutical or biotechnological possibilities of more immediate use. Many different strategies have been used prospecting the biodiversity of Earth in the search for novel structure-activity relationships, which has resulted in important discoveries in drug development. However, we believe that the development of multidisciplinary incentives will be necessary for a future successful exploration of Nature. With this aim, one way would be a modernization and renewal of a venerable proven interdisciplinary science, Pharmacognosy, which represents an integrated way of studying biological systems. This has been demonstrated based on an explanatory model where the different parts of the model are explained by our ongoing research. Anti-inflammatory natural products have been discovered based on ethnopharmacological observations, marine sponges in cold water have resulted in substances with ecological impact, combinatory strategy of ecology and chemistry has revealed new insights into the biodiversity of fungi, in depth studies of cyclic peptides (cyclotides) has created new possibilities for engineering of bioactive peptides, development of new strategies using phylogeny and chemography has resulted in new possibilities for navigating chemical and biological space, and using bioinformatic tools for understanding of lateral gene transfer could provide potential drug targets. A multidisciplinary subject like Pharmacognosy, one of several scientific disciplines bridging biology and chemistry with medicine, has a strategic position for studies of complex scientific questions based on observations in Nature. Furthermore, natural product research based on intriguing scientific questions in Nature can be of value to increase the attraction for young students in modern life science.

Neuroscience continues to experience a tremendous growth in data; in terms of the volume and variety of data, the velocity at which data is acquired, and in turn the veracity of data. These challenges are a serious impediment to sharing of data, analyses, and tools within and across labs. Here, we introduce BRAINformat, a novel data standardization framework for the design and management of scientific data formats. The BRAINformat library defines application-independent design concepts and modules that together create a general framework for standardization of scientific data. We describe the formal specification of scientific data standards, which facilitates sharing and verification of data and formats. We introduce the concept of Managed Objects, enabling semantic components of data formats to be specified as self-contained units, supporting modular and reusable design of data format components and file storage. We also introduce the novel concept of Relationship Attributes for modeling and use of semantic relationships between data objects. Based on these concepts we demonstrate the application of our framework to design and implement a standard format for electrophysiology data and show how data standardization and relationship-modeling facilitate data analysis and sharing. The format uses HDF5, enabling portable, scalable, and self-describing data storage and integration with modern high-performance computing for data-driven discovery.

[A collection of scientific instruments at the dawn of the modern hospital: Vincenzo Viviani's physical-mathematical instruments and Santa Maria Hospital in Florence (1871-1895)].

PubMed

Diana, Esther

2008-01-01

Around the second half of the nineteenth century, the collection of physics-mathematical instruments that Vincenzo Viviani (1622-1703) had bequeathed to the Santa Maria Nuova Hospital of Florence stirred new interest. The process of modernising the hospital was indeed to lead to the progressive alienation of the institution's rich historical patrimony, including the scientific collections. In tracing back the negotiations that led to the sale of the Viviani collection, archive documents have also brought to light the collection inventory, which is now proposed a new to help recount the history of how scientific instruments became museum collectibles in Florence.

Nomadic concepts in the history of biology.

Surman, Jan; Stráner, Katalin; Haslinger, Peter

2014-12-01

The history of scientific concepts has firmly settled among the instruments of historical inquiry. In our section we approach concepts from the perspective of nomadic concepts (Isabelle Stengers). Instead of following the evolution of concepts within one disciplinary network, we see them as subject to constant reification and change while crossing and turning across disciplines and non-scientific domains. This introduction argues that understanding modern biology is not possible without taking into account the constant transfers and translations that affected concepts. We argue that this approach does not only engage with nomadism between disciplines and non-scientific domains, but reflects on and involves the metaphoric value of concepts as well.

While the primary product of scientific visualization is images and movies, its primary objective is really scientific insight. Too often, the focus of visualization research is on the product, not the mission. This paper presents two case studies, both that appear in previous publications, that focus on using visualization technology to produce insight. The first applies"Query-Driven Visualization" concepts to laser wakefield simulation data to help identify and analyze the process of beam formation. The second uses topological analysis to provide a quantitative basis for (i) understanding the mixing process in hydrodynamic simulations, and (ii) performing comparative analysis of data frommore » two different types of simulations that model hydrodynamic instability.« less

Ancient texts to PubMed: a brief history of the peer-review process.

The formal evaluation of scientific literature by invited referees (peer reviewers) is a relatively recent phenomenon and now is considered a cornerstone of modern science. However, its roots can be traced back to antiquity. As the speed and complexity of scientific information and publishing increases in the digital age, peer review must continue to evolve. To understand the future direction of peer review, we must understand its past. Here, we briefly explore the history of scientific peer review. This may help us predict and design appropriate peer review for the new era.

[Science in the crosshairs of enlightenment. Significance of hypothetical thinking].

PubMed

Wieland, Wolfgang

2011-01-01

To further the enlightenment primarily or even only by means of science was the hope of most representatives of the movement of the enlightenment which gave its name to a whole period of European cultural history. Only a few of its representatives, like Montesquieu and Rousseau, doubted for good reasons, whether and how the goals of the enlightenment can be reached at all by the means of science alone. In his Discours préliminaires to the Encyclopédie D'Alembert still wanted to limit science proper to the narrower field of those kinds of research which were strictly based on observations and calculations alone. In this way he remained committed to Descartes' ideal method of receiving authentic knowledge only by deduction from evident axioms or fundamental theorems. Pascal's casual discovery of the calculation of probabilities allowed to apply mathematics on the hidden laws of the apparent casualties of the human life world. Bacon's project of empirical science as a rational and methodological art of conducting experiments could replace the methodological ideal of science more geometrico. Lichtenberg's refined sensibility for the subjunctive linguistic forms of hypothetical thinking indicates a new understanding of inventing and testing hypotheses as the two most important methods of the experimental sciences when compared to the formal sciences of logic and mathematics. Whoever is studying the history of science of modern times in the cross wire of the enlightenment, will realize soon that science has always been in need of being illuminated about its own chances, risks and side effects. The project of enlightenment through science had to be complemented by the project of an enlightenment about science right from its beginning. Because of the implicit risks and side effects the project of enlightenment has to be enlightenment despite of science and because of science. On the one hand, as a special form of human practice the sciences are directed towards theoretical goals and practical purposes such that their agents cannot be conscious of all aspects of their practices in advance and reflect about all of them at the same time. On the other hand, the agents of such scientific practices are rarely trained, to analyze the cognitive implications of their own actions with the conceptual means of philosophical analysis. Furthermore, the agents of scientific research are hardly able to foresee the theoretical results of their research or even predict the chances and risks of eventual applications with the methods of the social sciences. Despite of the chastening experiences with the ambivalence of the theoretical results and practical applications of the modern sciences and despite of the illuminating effects of modern history and theory of science, contemporary scientists are not fully conscious yet of what they are really doing and what science really is. The contemplative ideal of scientific investigations for their own sake has been replaced in modern times by the practical ideal of scientific research in the service of humanity. The emancipation of the modem sciences from philosophical authorities and religious institutions has freed at first the sciences from alien restrictions to their self-chosen objects and purposes of research. However, the increasing economic constraints and the political dependences prevented even more so that scientists could realize the autonomy which the representatives of the enlightenment had been hoping for. KANT defined the goal of enlightenment as "man's emergence from his self-incurred immaturity". Quoting HORACE'S Sapere aude! he appealed to the courage of his comrades to use their own reason without the guidance of others in philosophical and especially in religious matters. Intellectual maturity as the proper goal of the enlightenment remained to be an undelivered promise despite of the emancipation of the sciences from traditional philosophical authorities and religious institutions. It is not only arguable whether or not enlightenment in this understanding is possible for most people, but also whether it is even desirable for all people considering the implicit ambivalence of the modern sciences. Kant's main philosophical works can be adequately interpreted as the first and unique attempt to understand the potential of the cognitive capacities of human beings about the chances and risks of enlightenment itself by means of a critical inquiry. This holds especially for the practical fruits of the enlightenment as, e.g., with respect to the emancipation from superstition and the appeal to religious tolerance, to the republican idea of the state and the establishment of civil and human rights, to the humanization of the law and execution of legal penalty as well as the unalienable rights of each individual human being.

Therapeutic Potential of Plants as Anti-microbials for Drug Discovery

PubMed Central

Perumal Samy, Ramar

2010-01-01

The uses of traditional medicinal plants for primary health care have steadily increased worldwide in recent years. Scientists are in search of new phytochemicals that could be developed as useful anti-microbials for treatment of infectious diseases. Currently, out of 80% of pharmaceuticals derived from plants, very few are now being used as anti-microbials. Plants are rich in a wide variety of secondary metabolites that have found anti-microbial properties. This review highlights the current status of traditional medicine, its contribution to modern medicine, recent trends in the evaluation of anti-microbials with a special emphasis upon some tribal medicine, in vitro and in vivo experimental design for screening, and therapeutic efficacy in safety and human clinical trails for commercial outlet. Many of these commercially available compounds are crude preparations administered without performing human clinical trials. Recent methods are useful to standardize the extraction for scientific investigation of new phytochemicals and anti-microbials of traditionally used plants. It is concluded that once the local ethnomedical preparations of traditional sources are scientifically evaluated before dispensing they should replace existing drugs commonly used for the therapeutic treatment of infection. This method should be put into practice for future investigations in the field of ethnopharmacology, phytochemistry, ethnobotany and other biological fields for drug discovery. PMID:18955349

Study/experimental/research design: much more than statistics.

PubMed

Knight, Kenneth L

2010-01-01

The purpose of study, experimental, or research design in scientific manuscripts has changed significantly over the years. It has evolved from an explanation of the design of the experiment (ie, data gathering or acquisition) to an explanation of the statistical analysis. This practice makes "Methods" sections hard to read and understand. To clarify the difference between study design and statistical analysis, to show the advantages of a properly written study design on article comprehension, and to encourage authors to correctly describe study designs. The role of study design is explored from the introduction of the concept by Fisher through modern-day scientists and the AMA Manual of Style. At one time, when experiments were simpler, the study design and statistical design were identical or very similar. With the complex research that is common today, which often includes manipulating variables to create new variables and the multiple (and different) analyses of a single data set, data collection is very different than statistical design. Thus, both a study design and a statistical design are necessary. Scientific manuscripts will be much easier to read and comprehend. A proper experimental design serves as a road map to the study methods, helping readers to understand more clearly how the data were obtained and, therefore, assisting them in properly analyzing the results.

Modern Scientific Literacy: A Case Study of Multiliteracies and Scientific Practices in a Fifth Grade Classroom

2018-01-01

This study investigates the convergence of multiliteracies and scientific practices in a fifth grade classroom. As students' lives become increasingly multimodal, diverse, and globalized, the traditional notions of literacy must be revisited (New London Group 1996). With the adoption of the Next Generation Science Standards (NGSS Lead States 2013a) in many states, either in their entirety or in adapted forms, it becomes useful to explore the interconnectedness multiliteracies and scientific practices and the resulting implications for scientific literacy. The case study included a fifth grade classroom, including the students and teacher. In order to create a rich description of the cases involved, data were collected and triangulated through teacher interviews, student interviews and focus groups, and classroom observations. Findings reveal that as science activities were enriched with multiliteracies and scientific practices, students were engaged in developing skills and knowledge central to being scientifically literate. Furthermore, this study establishes that characteristics of scientific literacy, by its intent and purpose, are a form of multiliteracies in elementary classrooms. Therefore, the teaching and learning of science and its practices for scientific literacy are in turn reinforcing the development of broader multiliteracies.

A 100-Year Review: Methods and impact of genetic selection in dairy cattle-From daughter-dam comparisons to deep learning algorithms.

Weigel, K A; VanRaden, P M; Norman, H D; Grosu, H

2017-12-01

In the early 1900s, breed society herdbooks had been established and milk-recording programs were in their infancy. Farmers wanted to improve the productivity of their cattle, but the foundations of population genetics, quantitative genetics, and animal breeding had not been laid. Early animal breeders struggled to identify genetically superior families using performance records that were influenced by local environmental conditions and herd-specific management practices. Daughter-dam comparisons were used for more than 30 yr and, although genetic progress was minimal, the attention given to performance recording, genetic theory, and statistical methods paid off in future years. Contemporary (herdmate) comparison methods allowed more accurate accounting for environmental factors and genetic progress began to accelerate when these methods were coupled with artificial insemination and progeny testing. Advances in computing facilitated the implementation of mixed linear models that used pedigree and performance data optimally and enabled accurate selection decisions. Sequencing of the bovine genome led to a revolution in dairy cattle breeding, and the pace of scientific discovery and genetic progress accelerated rapidly. Pedigree-based models have given way to whole-genome prediction, and Bayesian regression models and machine learning algorithms have joined mixed linear models in the toolbox of modern animal breeders. Future developments will likely include elucidation of the mechanisms of genetic inheritance and epigenetic modification in key biological pathways, and genomic data will be used with data from on-farm sensors to facilitate precision management on modern dairy farms.

A Virtual Tour of the 1868 Hayward Earthquake in Google EarthTM

NASA Astrophysics Data System (ADS)

Lackey, H. G.; Blair, J. L.; Boatwright, J.; Brocher, T.

2007-12-01

The 1868 Hayward earthquake has been overshadowed by the subsequent 1906 San Francisco earthquake that destroyed much of San Francisco. Nonetheless, a modern recurrence of the 1868 earthquake would cause widespread damage to the densely populated Bay Area, particularly in the east Bay communities that have grown up virtually on top of the Hayward fault. Our concern is heightened by paleoseismic studies suggesting that the recurrence interval for the past five earthquakes on the southern Hayward fault is 140 to 170 years. Our objective is to build an educational web site that illustrates the cause and effect of the 1868 earthquake drawing on scientific and historic information. We will use Google EarthTM software to visually illustrate complex scientific concepts in a way that is understandable to a non-scientific audience. This web site will lead the viewer from a regional summary of the plate tectonics and faulting system of western North America, to more specific information about the 1868 Hayward earthquake itself. Text and Google EarthTM layers will include modeled shaking of the earthquake, relocations of historic photographs, reconstruction of damaged buildings as 3-D models, and additional scientific data that may come from the many scientific studies conducted for the 140th anniversary of the event. Earthquake engineering concerns will be stressed, including population density, vulnerable infrastructure, and lifelines. We will also present detailed maps of the Hayward fault, measurements of fault creep, and geologic evidence of its recurrence. Understanding the science behind earthquake hazards is an important step in preparing for the next significant earthquake. We hope to communicate to the public and students of all ages, through visualizations, not only the cause and effect of the 1868 earthquake, but also modern seismic hazards of the San Francisco Bay region.

The predictive state: Science, territory and the future of the Indian climate.

PubMed

Mahony, Martin

2014-02-01

Acts of scientific calculation have long been considered central to the formation of the modern nation state, yet the transnational spaces of knowledge generation and political action associated with climate change seem to challenge territorial modes of political order. This article explores the changing geographies of climate prediction through a study of the ways in which climate change is rendered knowable at the national scale in India. The recent controversy surrounding an erroneous prediction of melting Himalayan glaciers by the Intergovernmental Panel on Climate Change provides a window onto the complex and, at times, antagonistic relationship between the Panel and Indian political and scientific communities. The Indian reaction to the error, made public in 2009, drew upon a national history of contestation around climate change science and corresponded with the establishment of a scientific assessment network, the Indian Network for Climate Change Assessment, which has given the state a new platform on which to bring together knowledge about the future climate. I argue that the Indian Network for Climate Change Assessment is indicative of the growing use of regional climate models within longer traditions of national territorial knowledge-making, allowing a rescaling of climate change according to local norms and practices of linking scientific knowledge to political action. I illustrate the complex co-production of the epistemic and the normative in climate politics, but also seek to show how co-productionist understandings of science and politics can function as strategic resources in the ongoing negotiation of social order. In this case, scientific rationalities and modes of environmental governance contribute to the contested epistemic construction of territory and the evolving spatiality of the modern nation state under a changing climate.

Historical and social contexts for scientific writing and use of passive voice: Toward an undergraduate science literacy course

NASA Astrophysics Data System (ADS)

Ding, Dan Xiong

The passive voice is a major stylistic feature of modern scientific discourse, but such a feature did not dominate scientific writing until the 1890s. It has its roots in the philosophical thoughts of experimental science of Francis Bacon and his followers such as Thomas Sprat and John Locke. In the early seventeenth century. Bacon called for a new science that emphasized collective knowledge of nature. Such a science was a cooperative and public enterprise in which scientists should work as a group to advance knowledge of nature. When science was moving gradually toward a public enterprise from the early seventeenth century, the passive voice gradually replaced the active voice in science writing as a dominant stylistic feature. The passive voice in scientific writing is thus historically and socially conditioned. Scientists take advantage of the linguistic functions of the passive voice to serve their rhetorical and pragmatic purposes such as presenting experiments as they are for others to reproduce and verify the results. It embodies two major conventions of scientific communities: (1) science is a public enterprise and (2) it is also a cooperative venture. Other conventions are related to these two: the collective authority of an scientific community is above the personal authority of any one individual scientist; science is not an infallible force, so any research result needs to be verified by a scientific community before it becomes knowledge; scientists use passive voice to approach their writing to make it appear as if it were objective; and science is a human profession. Therefore, we need to teach science students to use the passive voice, and more importantly, why and when to use it. We should emphasize writing practice to have students' see that they use passives rhetorically to present experimental processes, materials and methods.

Young people are the future of research, especially in nephrology. The prevalence of young nephrologists within the main scientific European societies varies from the 12% to 34% and the 20% of the ERA-EDTA members are less than 40 years old in 2013. Recently, the ERA-EDTA has launched a new platform, the Young Nephrologists Platform (YNP), which the aim is to become the first modern network of young nephrologists from Europe and beyond. YNP aims at promoting the aggregation of young people through modern communication channels such as social networks, blogs and through the construction of a database collecting information on attitudes and personal experiences of each young nephrologist. A mentorship program, focused and young-oriented clinical courses on hot topics and the direct involvement of young nephrologists in working groups and scientific studies are some of the other interesting initiatives driven by YNP. The future of nephrology belongs to the young and YNP could represent a good springboard for the professional growth of young nephrologists.

[Modernity in dreams and myths].

PubMed

Scopelliti, Paolo

2009-01-01

The very presence of myths in psychoanalysis raises questions about their scientific status: that leads to reconsider the whole issue of Freudian mythology in a non-medical manner, by envisaging it in the more general context of modern myths, both political and artistic. Special attention is then paid to Surrealism, as the only avant-garde movement at the same time focused on psychoanalysis and politics: the role played by dreams in foundering myths is examined in both Surrealism and psychoanalysis. Surrealistic myths, such as Dalí's Grand Paranoïaque Comestible, finally prove to be so non-oedipian as the Nazi Ubermensch myth; nevertheless, their comparison with Freudian mythology points out their common origin, as they all fulfilled the need of the mass society for a modern myth, able to express his deeply renewed self-awareness.

Fleck and the social constitution of scientific objectivity.

PubMed

Fagan, Melinda B

2009-12-01

Ludwik Fleck's theory of thought-styles has been hailed as a pioneer of constructivist science studies and sociology of scientific knowledge. But this consensus ignores an important feature of Fleck's epistemology. At the core of his account is the ideal of 'objective truth, clarity, and accuracy'. I begin with Fleck's account of modern natural science, locating the ideal of scientific objectivity within his general social epistemology. I then draw on Fleck's view of scientific objectivity to improve upon reflexive accounts of the origin and development of the theory of thought-styles, and reply to objections that Fleck's epistemological stance is self-undermining or inconsistent. Explicating the role of scientific objectivity in Fleck's epistemology reveals his view to be an internally consistent alternative to recent social accounts of scientific objectivity by Harding, Daston and Galison. I use these contrasts to indicate the strengths and weaknesses of Fleck's innovative social epistemology, and propose modifications to address the latter. The result is a renewed version of Fleck's social epistemology, which reconciles commitment to scientific objectivity with integrated sociology, history and philosophy of science.

Scientific advancement is often spurred by the development of new instruments for investigation. Over the last several decades, many new instruments have been produced to further our understanding of the physiology of the human brain. We present a partial overview of some of these instruments, paying particular attention to those which record the electrical activity of the human brain. We preface the review with a brief primer on neuroanatomy and physiology, followed by a discussion of the latest types of apparatus used to investigate various properties of the central nervous system. A special focus is on microelectrode investigations that employ both intracellular and extracellular methods of recording the electrical activity of single neurons; another is on the modern electroencephalographic, electrocorticographic, and magnetoencephalographic methods used to study the spontaneous and evoked field potentials of the brain. Some examples of clinical applications are included, where appropriate.

Direct digital conversion detector technology

NASA Astrophysics Data System (ADS)

Mandl, William J.; Fedors, Richard

1995-06-01

Future imaging sensors for the aerospace and commercial video markets will depend on low cost, high speed analog-to-digital (A/D) conversion to efficiently process optical detector signals. Current A/D methods place a heavy burden on system resources, increase noise, and limit the throughput. This paper describes a unique method for incorporating A/D conversion right on the focal plane array. This concept is based on Sigma-Delta sampling, and makes optimum use of the active detector real estate. Combined with modern digital signal processors, such devices will significantly increase data rates off the focal plane. Early conversion to digital format will also decrease the signal susceptibility to noise, lowering the communications bit error rate. Computer modeling of this concept is described, along with results from several simulation runs. A potential application for direct digital conversion is also reviewed. Future uses for this technology could range from scientific instruments to remote sensors, telecommunications gear, medical diagnostic tools, and consumer products.

The natural history of Halley's comet

1981-07-01

The 1986 apparition of Halley's comet will be the subject of numerous space probes, planned to determine the chemical nature and physical structure of comet nuclei, atmospheres, and ionospheres, as well as comet tails. The problems of cometary origin remain inconclusive, with theories ranging from a purely interstellar origin to their being ejecta from the Galilean satellites of Jupiter. Comets can be grouped into one of two classes, depending on their periodicity, and statistical mechanics of the entire Jovian family of comets can be examined under the equilibrium hypothesis. Comet anatomy estimations have been determined, and there is speculation that comet chemistry may have been a factor in the origin of life on earth. Halley's comet was first noted using Newton's dynamical methods, and Brady (1972) attempted to use the comet as a gravitational probe in search of a trans-Plutonian planet. Halley's orbit is calculated by combination of ancient observations and modern scientific methods.

Measurements of carbon-14 with cavity ring-down spectroscopy

Accelerator Mass Spectrometry (AMS) is the most sensitive method for quantitation of 14C in biological samples. This technology has been used in a variety of low dose, human health related studies over the last 20 years when very high sensitivity was needed. AMS helped pioneer these scientific methods, but its expensive facilities and requirements for highly trained technical staff have limited their proliferation. Quantification of 14C by cavity ring-down spectroscopy (CRDS) offers an approach that eliminates many of the shortcomings of an accelerator-based system and would supplement the use of AMS in biomedical research. Our initial prototype, using a non-idealmore » wavelength laser and under suboptimal experimental conditions, has a 3.5-modern, 1-σ precision for detection of milligram-sized, carbon-14-elevated samples. Furthermore, these results demonstrate proof of principle and provided a starting point for the development of a spectrometer capable of biologically relevant sensitivities.« less

Advertising cadavers in the republic of letters: anatomical publications in the early modern Netherlands.

PubMed

Margócsy, Dániel

2009-06-01

This paper sketches how late seventeenth-century Dutch anatomists used printed publications to advertise their anatomical preparations, inventions and instructional technologies to an international clientele. It focuses on anatomists Frederik Ruysch (1638-1732) and Lodewijk de Bils (1624-69), inventors of two separate anatomical preparation methods for preserving cadavers and body parts in a lifelike state for decades or centuries. Ruysch's and de Bils's publications functioned as an 'advertisement' for their preparations. These printed volumes informed potential customers that anatomical preparations were aesthetically pleasing and scientifically important but did not divulge the trade secrets of the method of production. Thanks to this strategy of non-disclosure and advertisement, de Bils and Ruysch could create a well-working monopoly market of anatomical preparations. The 'advertising' rhetorics of anatomical publications highlight the potential dangers of equating the growth of print culture with the development of an open system of knowledge exchange.

Stapp's quantum dualism: The James and Heisenberg model of consciousness

NASA Astrophysics Data System (ADS)

Noyes, H. P.

1994-02-01

Henry Stapp attempts to resolve the Cartesian dilemma by introducing what the author would characterize as an ontological dualism between mind and matter. His model for mind comes from William James' description of conscious events and for matter from Werner Heisenberg's ontological model for quantum events (wave function collapse). His demonstration of the isomorphism between the two types of events is successful, but in the author's opinion fails to establish a monistic, scientific theory. The author traces Stapp's failure to his adamant rejection of arbitrariness, or 'randomness.' This makes it impossible for him (or for Bohr and Pauli before him) to understand the power of Darwin's explanation of biology, let alone the triumphs of modern 'neo-Darwinism.' The author notes that the point at issue is a modern version of the unresolved opposition between Leucippus and Democritus on one side and Epicurus on the other. Stapp's views are contrasted with recent discussions of consciousness by two eminent biologists: Crick and Edelman. They locate the problem firmly in the context of natural selection on the surface of the earth. Their approaches provide a sound basis for further scientific work. The author briefly examines the connection between this scientific (rather than ontological) framework and the new fundamental theory based on bit-strings and the combinatorial hierarchy.

Antikythera Calculator advances modern science of 19 centuries

NASA Astrophysics Data System (ADS)

Pastore, Giovanni

2010-08-01

The Greek astronomic calculator, discovered in the depth of the sea in a naval wreckage of the 1st century B.C. in front of the island of Antikythera, is the most amazing among the archaeological discoveries of last century. The mechanism immediately appeared like a device out of its time. After years of study this devise is still provoking a discussion between scientists and archaeologists because of the complexity and the modernity of the scientific knowledge the work presupposes. Its epicyclical gearings show the high level of the scientific culture reached in that period of history. The knowledge of the planetary motion, necessary to the design of the epicyclic gearing of the Calculator of Antikythera, presumes that ancient Greek scientists knew the planetary motion of the celestial bodies and had already achieved the same results that have been attributed to scientists 19 centuries later. The scientific value of this gear mechanism is indisputable because the inventor of the Calculator of Antikythera had the knowledge that was "re-discovered" centuries later as the heliocentric theory proposed by Niccolò Copernicus in 1543 ( De revolutionibus orbium coelestium), the universal gravitation law formulated by Isaac Newton in 1687 ( Philosophiae Naturalis Principia Mathematica), and the kinematic study of the epicyclical gearings published by Robert Willis in 1841 ( Principles of mechanism).

The Microcosm of Scientific Knowledge: Sceintists are Talking but Mostly to Each Other

NASA Astrophysics Data System (ADS)

Suleski, J.; Ibaraki, M.

2005-12-01

There is no question that scientists are communicating en masse. But with publication in journals as the main form of communication of research results, modern scientific communication methods are contributing to a major chasm of knowledge between the scientific community and the mainstream public. While publication in a scientific journal is an effective means to communicate results to the scientific community, it is an ineffective means to communicate to the general public that turns to mainstream news media to learn about scientific discoveries. With little effort made to communicate beyond the borders of journals, an alarmingly small number of papers ever are reported on in mainstream publications. During the target years of 1990-1992 and 1998-2000 there were over 5,300 accredited scientific journals in print. However, in those same years, less than 0.0005% of the papers published in those journals gained any attention from mainstream news media and mainstream audiences. This begs the question, that as scientists, is it sufficient to publish results in highly technical formats with only scientists as the intended audience? Or, has this trend lead to a great disparity between the knowledgeable elite and the general population? The recent catastrophe encountered in the United States Gulf Coast after Hurricane Katrina is a striking example of published scientific research failing to reach the general public. Hundreds of papers were published during the years 1980-2005 discussing the topic of the potential threat of hurricanes to the gulf coast, yet many citizens of the area were unaware of the severity of a possible storm and subsequent flooding. In the target years researched, none of the papers published on this topic was reported on in mainstream news media, severely restricting the audience. While the intended audiences of the papers went beyond the general public, information in the hands of the people who inhabit the area would have directly by action and indirectly by support for funding influenced the conditions they faced. At a time when a nation is scratching its head and wondering who to blame, it is acutely obvious that the scientific community must shoulder some responsibility for relying on traditional communication methods to convey research findings about the region. This research points to a clear need for scientists to make new efforts to communicate not just to a captive audience of fellow researchers, but to the mainstream decision-makers of the world. Since the majority of the public looks to mass media for scientific news, it is essential that the scientific community open channels of communication with news media and develop alternate forms of communication. As Albert Einstein astutely pointed out in 1954, ''It is just as important to make knowledge live and to keep it alive as to solve specific problems.''

Scientific teaching: defining a taxonomy of observable practices.

Over the past several decades, numerous reports have been published advocating for changes to undergraduate science education. These national calls inspired the formation of the National Academies Summer Institutes on Undergraduate Education in Biology (SI), a group of regional workshops to help faculty members learn and implement interactive teaching methods. The SI curriculum promotes a pedagogical framework called Scientific Teaching (ST), which aims to bring the vitality of modern research into the classroom by engaging students in the scientific discovery process and using student data to inform the ongoing development of teaching methods. With the spread of ST, the need emerges to systematically define its components in order to establish a common description for education researchers and practitioners. We describe the development of a taxonomy detailing ST's core elements and provide data from classroom observations and faculty surveys in support of its applicability within undergraduate science courses. The final taxonomy consists of 15 pedagogical goals and 37 supporting practices, specifying observable behaviors, artifacts, and features associated with ST. This taxonomy will support future educational efforts by providing a framework for researchers studying the processes and outcomes of ST-based course transformations as well as a concise guide for faculty members developing classes. © 2015 B.

Honoring Our Ethical Origins: Scientific Integrity and Geoethics, Past, Present, and Future

NASA Astrophysics Data System (ADS)

Gundersen, L. C.

2017-12-01

Current ethics policy owes much of its origins to Aristotle and his writings on virtue - including the idea that if we understand and rationally practice virtue and excellence, we will be our best selves. From this humble beginning emerged a number of more complex, ever evolving, ethical theories. The Hypocratic Oath and atrocities of World War II resulted in the roots of scientific integrity through the Nuremberg Code and the Belmont Report, which set ethical rules for human experimentation, including, respect, beneficence, and justice. These roots produced bioethics, medical ethics, environmental ethics, and geoethics. Geoethics has its origins in Europe and is being embraced in the U.S.A. It needs a respected place in the geoscience curriculum, especially as we face the global challenges of climate change and sustainability. Modern scientific integrity in the U.S.A., where research misconduct is defined as fabrication, falsification, and plagiarism, was derived from efforts of the 1980's through 1990's by the Nat'l Institutes of Health and Nat'l Academy of Sciences (NAS). This definition of misconduct has remained an immovable standard, excluding anything not of the scientific process, such as personal behaviors within the research environment. Modern scientific integrity codes and reports such as the Singapore Statement, the NAS' Fostering Integrity in Research, and current federal agency policies, provide standards of behavior to aspire to, and acknowledge the deleterious effects of certain behaviors and practices, but still hesitate to include them in formal definitions of research misconduct. Modern media is holding a mirror to what is happening in the research environment. There are conflicts of interest, misrepresentations of data and uncertainty, discrimination, harassment, bullying, misuse of funds, withholding of data and code, intellectual theft, and a host of others, that are having a serious detrimental effect on science. For science to have its best future, we as scientists need to nurture and encourage the best in ourselves and others, taking a cue from the ancient Greeks. We need to address conduct as a part of misconduct. Recent policies, including the AGU's are bravely moving forward in this direction. It is new and difficult ground, but we are scientists, and this is an experiment we need to do.

Teaching climate change in undergraduate courses

NASA Astrophysics Data System (ADS)

Sadler, Michael

2013-04-01

Although anthropogenic climate change is generally accepted in the scientific community, there is considerable skepticism among the general population and, therefore, in undergraduate students of all majors. Students are often asked by their peers, family members, and others, whether they ``believe'' climate change is occurring and what should be done about it (if anything). I will present my experiences and recommendations for teaching the physics of climate change to both physics and non-science majors. For non-science majors, the basic approach is to try to develop an appreciation for the scientific method (particularly peer-reviewed research) in a course on energy and the environment. For physics majors, the pertinent material is normally covered in their undergraduate courses in modern physics and thermodynamics. Nevertheless, it helps to review the basics, e.g. introductory quantum mechanics (discrete energy levels of atomic systems), molecular spectroscopy, and blackbody radiation. I have done this in a separate elective topics course, titled ``Physics of Climate Change,'' to help the students see how their knowledge gives them insight into a topic that is very volatile (socially and politically).

William James, Nitrous Oxide, and the Anaesthetic Revelation.

Moon, Jane S; Kuza, Catherine M; Desai, Manisha S

William James greatly influenced the fields of psychology, philosophy, and religion during the late 19 th and early 20 th centuries. This was the era of Modernism, a time when many writers rejected the certainty of Enlightenment ideals. Positivism, which rose to prominence in the early 19th century, had emphasized physical phenomena, empirical evidence, and the scientific method. Darwin's On the Origin of Species (1859), with its theory of natural selection, provided an explanation for the evolution of species apart from a divine Creator. Within this context, William James served as a "mediator between scientific agnosticism and the religious view of the world." James' own experience inhaling nitrous oxide played an important role in shaping his views. For James, the use of nitrous oxide served a key role in elucidating some of his most central ideas: 1) the value of religion, and the emphasis on mysticism and revelation (as opposed to theology and doctrine) as religion's foundation; 2) the universe as pluralistic (as opposed to absolutist, constant, eternal), driven by chance, experience, and change.

[From the struggle for freedom to the denial of evidence: history of the anti-vaccination movements in Europe].

PubMed

Tafuri, S; Martinelli, D; Prato, R; Germinario, C

2011-01-01

The 1853 Vaccination Act, adopted in England during XIX century, was the first law about compulsory vaccination in Europe. The Act caused a violent movement of opposition with the birth of Victorian anti-vaccination. The modern anti-vaccination movement was born in 1998 following a paper of Andrew Wakefield published in the Lancet. In this paper Wakefield illustrated a study of twenty patients and concluded that the administration of the MMR vaccine caused autism and some forms of colitis. The publication was later disowned by almost all authors. However the study of Wakefield caused a reduction of compliance to the anti-MMR vaccination in the United Kingdom, resulting in lower coverage and new outbreaks. The theorethical principles of anti-vaccinationists of 19th and 20th century were: the hypothesis that vaccines cause illnesses; the presence of toxic substances in the vaccine; the violation of freedom Personal and People's; the ineffectiveness of vaccinations. Moreover, anti-vaccinationists always refused the scientific methods and the peer-review of their scientific studies.

Application of modern scientific knowledge coupled with sensitive analytical technique is important for the quality evaluation and standardization of polyherbal formulations. Semecarpus anacardium, an important medicinal plant with wide medicinal properties, is frequently used in a large number of traditional herbal preparations. Tetrahydroamentoflavone (THA), a major bioactive biflavonoid was selected as a chemical marker of S. anacardium and RP-semi-preparative HPLC conditions were optimized for the isolation of tetrahydroamentoflavone. HPTLC analytical method was developed for the fingerprinting of S. anacardium flavonoids and quantification of tetrahydroamentoflavone. The method was validated in terms of their linearity, LOD, LOQ, precision and accuracy and compared with RP-HPLC-DAD method. The methods were demonstrated for the chemical fingerprinting of S. anacardium plant parts and some commercial polyherbal formulations and the amount of tetrahydroamentoflavone was quantified. HPTLC analysis showed that S. anacardium seed contained approximately 10 g kg(-1) of tetrahydroamentoflavone. The methods were able to identify and quantify tetrahydroamentoflavone from complex mixtures of phytochemicals and could be extended to the marker-based standardization of polyherbal formulations, containing S. anacardium.

Collaborative Group Learning Approaches for Teaching Comparative Planetology

Slater, S. J.; Slater, T. F.

2013-12-01

Modern science education reform documents propose that the teaching of contemporary students should focus on doing science, rather than simply memorizing science. Duschl, Schweingruber, and Shouse (2007) eloquently argue for four science proficiencies for students. Students should: (i) Know, use, and interpret scientific explanations of the natural world; (ii) Generate and evaluate scientific evidence and explanations; (iii) Understand the nature and development of scientific knowledge; and (iv) Participate productively in scientific practices and discourse. In response, scholars with the CAPER Center for Astronomy & Physics Education Research are creating and field-tested two separate instructional approaches. The first of these is a series of computer-mediated, inquiry learning experiences for non-science majoring undergraduates based upon an inquiry-oriented teaching approach framed by the notions of backwards faded-scaffolding as an overarching theme for instruction. Backwards faded-scaffolding is a strategy where the conventional and rigidly linear scientific method is turned on its head and students are first taught how to create conclusions based on evidence, then how experimental design creates evidence, and only at the end introduces students to the most challenging part of inquiry - inventing scientifically appropriate questions. Planetary science databases and virtual environments used by students to conduct scientific investigations include the NASA and JPL Solar System Simulator and Eyes on the Solar System as well as the USGS Moon and Mars Global GIS Viewers. The second of these is known widely as a Lecture-Tutorial approach. Lecture-Tutorials are self-contained, collaborative group activities. The materials are designed specifically to be easily integrated into the lecture course and directly address the needs of busy and heavily-loaded teaching faculty for effective, student-centered, classroom-ready materials that do not require a drastic course revision for implementation. Students are asked to reason about difficult concepts, while working in pairs, and to discuss their ideas openly. Extensive evaluation results consistently suggest that both the backwards faded-scaffolding and the Lecture-Tutorials approaches are successful at engaging students in self-directed scientific discourse as measured by the Views on Scientific Inquiry (VOSI) as well as increasing their knowledge of science as measured by the Test Of Atronomy STandards (TOAST).

Rapid Scientific Promotion of Scientific Productions in Stem Cells According to The Indexed Papers in The ISI (web of knowledge).

Alijani, Rahim

2015-01-01

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

New Trends in E-Science: Machine Learning and Knowledge Discovery in Databases

NASA Astrophysics Data System (ADS)

Brescia, Massimo

2012-11-01

Data mining, or Knowledge Discovery in Databases (KDD), while being the main methodology to extract the scientific information contained in Massive Data Sets (MDS), needs to tackle crucial problems since it has to orchestrate complex challenges posed by transparent access to different computing environments, scalability of algorithms, reusability of resources. To achieve a leap forward for the progress of e-science in the data avalanche era, the community needs to implement an infrastructure capable of performing data access, processing and mining in a distributed but integrated context. The increasing complexity of modern technologies carried out a huge production of data, whose related warehouse management and the need to optimize analysis and mining procedures lead to a change in concept on modern science. Classical data exploration, based on local user own data storage and limited computing infrastructures, is no more efficient in the case of MDS, worldwide spread over inhomogeneous data centres and requiring teraflop processing power. In this context modern experimental and observational science requires a good understanding of computer science, network infrastructures, Data Mining, etc. i.e. of all those techniques which fall into the domain of the so called e-science (recently assessed also by the Fourth Paradigm of Science). Such understanding is almost completely absent in the older generations of scientists and this reflects in the inadequacy of most academic and research programs. A paradigm shift is needed: statistical pattern recognition, object oriented programming, distributed computing, parallel programming need to become an essential part of scientific background. A possible practical solution is to provide the research community with easy-to understand, easy-to-use tools, based on the Web 2.0 technologies and Machine Learning methodology. Tools where almost all the complexity is hidden to the final user, but which are still flexible and able to produce efficient and reliable scientific results. All these considerations will be described in the detail in the chapter. Moreover, examples of modern applications offering to a wide variety of e-science communities a large spectrum of computational facilities to exploit the wealth of available massive data sets and powerful machine learning and statistical algorithms will be also introduced.

Over the last several decades, science has benefited tremendously by the implementation of digital electronic components for analytical instrumentation. A pioneer in this area of scientific inquiry was Howard Malmstadt. Frequently, such revolutions in scientific history can be viewed as a series of discoveries without a great deal of attention as to how mentorship shapes the careers and methodologies of those who made great strides forward for science. This paper focuses on the verifiable relationships of those who are connected through the academic tree of Malmstadt and how their experiences and the context of world events influenced their scientific pursuits. Particular attention is dedicated to the development of American chemistry departments and the critical role played by many of the individuals in the tree in this process. © The Author(s) 2016.

Exploring multiliteracies, student voice, and scientific practices in two elementary classrooms

NASA Astrophysics Data System (ADS)

Allison, Elizabeth Rowland

This study explored the voices of children in a changing world with evolving needs and new opportunities. The workplaces of rapidly moving capitalist societies value creativity, collaboration, and critical thinking skills which are of growing importance and manifesting themselves in modern K-12 science classroom cultures (Gee, 2000; New London Group, 2000). This study explored issues of multiliteracies and student voice set within the context of teaching and learning in 4th and 5th grade science classrooms. The purpose of the study was to ascertain what and how multiliteracies and scientific practices (NGSS Lead States, 2013c) are implemented, explore how multiliteracies influence students' voices, and investigate teacher and student perceptions of multiliteracies, student voice, and scientific practices. Grounded in a constructivist framework, a multiple case study was employed in two elementary classrooms. Through observations, student focus groups and interviews, and teacher interviews, a detailed narrative was created to describe a range of multiliteracies, student voice, and scientific practices that occurred with the science classroom context. Using grounded theory analysis, data were coded and analyzed to reveal emergent themes. Data analysis revealed that these two classrooms were enriched with multiliteracies that serve metaphorically as breeding grounds for student voice. In the modern classroom, defined as a space where information is instantly accessible through the Internet, multiliteracies can be developed through inquiry-based, collaborative, and technology-rich experiences. Scientific literacy, cultivated through student communication and collaboration, is arguably a multiliteracy that has not been considered in the literature, and should be, as an integral component of overall individual literacy in the 21st century. Findings revealed four themes. Three themes suggest that teachers address several modes of multiliteracies in science, but identify barriers to integrating multiliteracies and scientific practices into science teaching. The issues include time, increased standards accountability, and lack of comfort with effective integration of technology. The fourth theme revealed that students have the ability to shape and define their learning while supporting other voices through collaborative science experiences.

In late 1915, Albert Einstein (1879-1955) completed as series of papers on a generalized theory of gravitation that were to constitute a major conceptual change in the history of modern physics and the crowning achievement of his scientific career. But this accomplishment came after a decade of intense intellectual struggle and was received with muted enthusiasm. Einstein's previously unpublished writings and massive correspondence, edited by the Einstein Papers Project, provide vivid insights into the historical, personal, and scientific context of the formulation, completion, and reception of GR during the first decades of the 20th century.

Quality assurance of the university medical education, hospital services and traditional pharmaceutical products of the Bhutanese So-wa-rig-pa health care system.

Wangchuk, Phurpa; Tashi, ᅟ

2016-08-12

The Bhutanese So-wa-rig-pa medicine (BSM) was integrated with the allopathic (modern) health care system in 1967. Ever since the health care integration policy was implemented, the BSM has gone through many phases of quality improvement and changes including the establishment of one university-based institute, 58 hospitals and Basic Health Units (BHU)-based health care services, and one traditional medicine factory. The BSM provides primary health care services to more than 20-30 % of patients who visit hospitals and BHU on a daily basis. However, there has been no study covering the quality assurance system of BSM. Our paper addresses this information gap. This study was an observational ethnographic study supported by phenomenological understanding and content analysis of the data. The information was triangulated through consultation with the BSM practitioners (discussion (N = 8)) and personalized in-depth question-answer sessions using electronic protocols (N = 5). These participants comprised BSM educationists, clinical physicians, researchers, production and the quality assurance staff who were selected using convenience and purposive sampling method. The relevant So-wa-rig-pa information and literature were obtained from the government policy documents, official websites, scientific papers and the traditional medical texts. This study is enhanced by our practical observations and first-hand experience with BSM while working as the researchers at the Ministry of Health in Bhutan. In addition, the information in this paper is crosschecked and authenticated by five So-wa-rig-pa practitioners of Bhutan. The study highlights the following: a) The BSM receives both the government and people's support, b) The quality assurance system have been developed by integrating the traditional empirical knowledge and modern scientific protocols, c) There exist three administrative and functional organizations responsible for providing the quality BSM health care services in Bhutan, d) Extensive standard treatment guidelines and Quality documentation system exist for BSM as required by the regulatory bodies in Bhutan. The paper also recommends appropriate future directions for BSM. The BSM plays significant role in the primary health care system of the country. Consequently, the quality, safety and efficacy of BSM has been given priority by the Bhutan government. Many scientific protocols were integrated with the traditional quality approaches and further scientific studies are still required to improve its quality.

"[N]ot subject to our sense” : Margaret Cavendish's fusion of Renaissance science, magic and fairy lore.

PubMed

Walters, Lisa

2010-01-01

This article explores Margaret Cavendish's depictions of alchemy, witchcraft and fairy lore in her scientific treatise Philosophical Letters and in fictional texts from Natures Pictures and Poems and Fancies. Though Cavendish was a dedicated materialist, she appropriates theories of magic from early modern science and folklore into her materialist epistemology. As Cavendish draws upon a fusion of early modern conceptions of magic, she creates a radical theory of matter which not only challenges patriarchy and binary oppositions, but also explores the plurality and mystery that can exist within an infinitely complex material world.

This included new, highly sensitive tracking cameras, control computers, filter wheels and other equipment, as well as a major redesign of the control software. The experiences along the migration path from an aged 19" VMbus based control system to the application of modern industrial PCs, from VxWorks real-time operating system to embedded Linux and a state of the art software architecture are presented. Further, the concept is presented to operate the new camera also as a scientific instrument, in parallel to tracking.

Flexible End2End Workflow Automation of Hit-Discovery Research.

Holzmüller-Laue, Silke; Göde, Bernd; Thurow, Kerstin

2014-08-01

The article considers a new approach of more complex laboratory automation at the workflow layer. The authors purpose the automation of end2end workflows. The combination of all relevant subprocesses-whether automated or manually performed, independently, and in which organizational unit-results in end2end processes that include all result dependencies. The end2end approach focuses on not only the classical experiments in synthesis or screening, but also on auxiliary processes such as the production and storage of chemicals, cell culturing, and maintenance as well as preparatory activities and analyses of experiments. Furthermore, the connection of control flow and data flow in the same process model leads to reducing of effort of the data transfer between the involved systems, including the necessary data transformations. This end2end laboratory automation can be realized effectively with the modern methods of business process management (BPM). This approach is based on a new standardization of the process-modeling notation Business Process Model and Notation 2.0. In drug discovery, several scientific disciplines act together with manifold modern methods, technologies, and a wide range of automated instruments for the discovery and design of target-based drugs. The article discusses the novel BPM-based automation concept with an implemented example of a high-throughput screening of previously synthesized compound libraries. © 2014 Society for Laboratory Automation and Screening.

Reducing Seismic Hazard and Building Capacity Through International Cooperation

During the last 50 years, the Caucasus, Central Asia and the Caspian Sea regions have experienced several devastating earthquakes. While each country in the region has worked with its neighbors on small, ad-hoc projects to improve preparedness, deeply ingrained political and ethnic rivalries, and severely stressed economies have severely hindered sustained regional cooperation. Future damaging earthquakes are inevitable and without proper planning the negative impact on public safety, security, economics and stability in these regions will be devastating. We have, through twelve years of international scientific cooperation, focused on the development of an expanded skill base and infrastructure, through the installation of new, modern, digital seismic monitoring networks, building of historic databases, sharing seismic, geologic and geophysical data, conducting joint scientific investigations utilizing the new digital data and applying modern techniques, as well as the development of regional hazard models that the scientists of the region share with their governments and use to advise them on the best ways to mitigate the impact of a damaging earthquake. We have established specialized regional scientific task-force teams who can carry out seismological, geological and engineering studies in the epicentral zone, including the collection of new scientific data, for better understanding of seismic and geodynamic processes as well to provide emergency support in crisis and post-crisis situations in the Southern Caucasus countries. "Secrecy" in crisis and post-crisis situations in the former Soviet Union countries, as well as political instabilities, led to an absence of seismic risk reduction and prevention measures as well as little to no training of scientific-technical personnel who could take action in emergency situations. There were few opportunities for the development of a next generation of scientific experts, thus we have placed emphasis on the inclusion and development of young scientists who are able to advise their countries' decision makers in the future. By building a common and shared set of databases, making available new modern, scientific tools, and providing joint training field exercises we are working to enable the countries to make independent decisions about their infrastructures and to pool their resources in the event of another earthquake. Out of the earthquakes' devastation has come a positive outcome: a scientific partnership to address the seismic hazards along one of the world's most tectonically active regions. This is contributing to a rapprochement of the scientists, decision makers, and politicians in this region. This work was supported through the following international projects: ISTC A-1418 Project "Open Network of Scientific Centers for Mitigation Risk of Natural Hazards in the Southern Caucasus and Central Asia", ISTC CSP-053 Project "Development of Communication System for Seismic Hazard Situations in the Southern Caucasus and Central Asia", and NATO SfP- 983284 Project "Caucasus Seismic Emergency Response", with participants from the Southern Caucasus countries, the US, Greece, Turkey, and France.

Forming, transfer and globalization of medical-pharmaceutical knowledge in South East Asian missions (17th to 18th c.) - historical dimensions and modern perspectives.

PubMed

Anagnostou, Sabine

2015-06-05

From the 17th to the 18th centuries, missionaries in Southeast Asia dedicated themselves to providing and establishing a professional medical-pharmaceutical supply for the local population and therefore explored the genuine Materia medica for easily available and affordable remedies, especially medicinal plants. In characteristic medical-pharmaceutical compendia, which can be classified as missionary pharmacopoeias, they laid down their knowledge to advise others and to guarantee a professional health care. As their knowledge often resulted from an exchange with indigenous communities, these compendia provide essential information about traditional plant uses of Southeast Asian people. Individual missionaries such as the Jesuit Georg Joseph Kamel (1661-1706) not only strove to explore medicinal plants but performed botanical studies and even composed comprehensive herbals. The Jesuit missionaries in particular played roles in both the order's own global network of transfer of medicinal drugs and knowledge about the application, and within the contemporary local and European scientific networks which included, for example, the famous Royal Society of London. The results of their studies were distributed all over the world, were introduced into the practical Materia medica of other regions, and contributed significantly to the academization of knowledge. In our article we will explain the different intentions and methods of exploring, the resulting works and the consequences for the forming of the pharmaceutical and scientific knowledge. Finally, we will show the options which the works of the missionaries can offer for the saving of traditional ethnopharmacological knowledge and for the development of modern phytotherapeutics and pharmaceutical supply. The publication is based on a comprehensive study on the phenomenon of missionary pharmacy which has been published as a book in 2011 (Anagnostou, 2011a) and shows now the potential of historical medical-pharmaceutical works written in the Asian missions of the 17th to 18th century and influenced by ethnopharmaceutical knowledge and the relevance of historical studies for modern investigation in phytotherapy.

New insights from DEM's into form, process and causality in Distributive Fluvial Systems

NASA Astrophysics Data System (ADS)

Scuderi, Louis; Weissmann, Gary; Hartley, Adrian; Kindilien, Peter

2014-05-01

Recent developments in platforms and sensors, as well as advances in our ability to access these rich data sources in near real time presents geoscientists with both opportunities and problems. We currently record raster and point cloud data about the physical world at unprecedented rates with extremely high spatial and spectral resolution. Yet the ability to extract scientifically useful knowledge from such immense data sets has lagged considerably. The interrelated fields of database creation, data mining and modern geostatistics all focus on such interdisciplinary data analysis problems. In recent years these fields have made great advances in analyzing the complex real-world data such as that captured in Digital Elevation Models (DEM's) and satellite imagery and by LIDAR and other geospatially referenced data sets. However, even considering the vast increase in the use of these data sets in the past decade these methods have enjoyed only a relatively modest penetration into the geosciences when compared to data analysis in other scientific disciplines. In part, a great deal of the current research weakness is due to the lack of a unifying conceptual approach and the failure to appreciate the value of highly structured and synthesized compilations of data, organized in user-friendly formats. We report on the application of these new technologies and database approaches to global scale parameterization of Distributive Fluvial Systems (DFS) within continental sedimentary basins and illustrate the value of well-constructed databases and tool-rich analysis environments for understanding form, process and causality in these systems. We analyzed the characteristics of aggradational fluvial systems in more than 700 modern continental sedimentary basins and the links between DFS within these systems and their contributing drainage basins. Our studies show that in sedimentary basins, distributive fluvial and alluvial systems dominate the depositional environment. Consequently, we have found that studies of modern tributary drainage systems in degradational settings are likely insufficient for understanding the geomorphology expressed within these basins and ultimately for understanding the basin-scale architecture of dominantly distributive fluvial deposits preserved in the rock record.

Marginalia, commonplaces, and correspondence: scribal exchange in early modern science.

PubMed

Yale, Elizabeth

2011-06-01

In recent years, historians of science have increasingly turned their attention to the "print culture" of early modern science. These studies have revealed that printing, as both a technology and a social and economic system, structured the forms and meanings of natural knowledge. Yet in early modern Europe, naturalists, including John Aubrey, John Evelyn, and John Ray, whose work is discussed in this paper, often shared and read scientific texts in manuscript either before or in lieu of printing. Scribal exchange, exemplified in the circulation of writings like commonplace books, marginalia, manuscript treatises, and correspondence, was the primary means by which communities of naturalists constructed scientific knowledge. Print and manuscript were necessary partners. Manuscript fostered close collaboration, and could be circulated relatively cheaply; but, unlike print, it could not reliably secure priority or survival for posterity. Naturalists approached scribal and print communication strategically, choosing the medium that best suited their goals at any given moment. As a result, print and scribal modes of disseminating information, constructing natural knowledge, and organizing communities developed in tandem. Practices typically associated with print culture manifested themselves in scribal texts and exchanges, and vice versa. "Print culture" cannot be hived off from "scribal culture." Rather, in their daily jottings and exchanges, naturalists inhabited, and produced, one common culture of communication. Copyright © 2010 Elsevier Ltd. All rights reserved.

DCMS: A data analytics and management system for molecular simulation.

PubMed

Kumar, Anand; Grupcev, Vladimir; Berrada, Meryem; Fogarty, Joseph C; Tu, Yi-Cheng; Zhu, Xingquan; Pandit, Sagar A; Xia, Yuni

Molecular Simulation (MS) is a powerful tool for studying physical/chemical features of large systems and has seen applications in many scientific and engineering domains. During the simulation process, the experiments generate a very large number of atoms and intend to observe their spatial and temporal relationships for scientific analysis. The sheer data volumes and their intensive interactions impose significant challenges for data accessing, managing, and analysis. To date, existing MS software systems fall short on storage and handling of MS data, mainly because of the missing of a platform to support applications that involve intensive data access and analytical process. In this paper, we present the database-centric molecular simulation (DCMS) system our team developed in the past few years. The main idea behind DCMS is to store MS data in a relational database management system (DBMS) to take advantage of the declarative query interface ( i.e. , SQL), data access methods, query processing, and optimization mechanisms of modern DBMSs. A unique challenge is to handle the analytical queries that are often compute-intensive. For that, we developed novel indexing and query processing strategies (including algorithms running on modern co-processors) as integrated components of the DBMS. As a result, researchers can upload and analyze their data using efficient functions implemented inside the DBMS. Index structures are generated to store analysis results that may be interesting to other users, so that the results are readily available without duplicating the analysis. We have developed a prototype of DCMS based on the PostgreSQL system and experiments using real MS data and workload show that DCMS significantly outperforms existing MS software systems. We also used it as a platform to test other data management issues such as security and compression.

The NOAA Ship Okeanos Explorer Education Materials Collection: Bringing Ocean Exploration Alive for Teachers and Students

NASA Astrophysics Data System (ADS)

Haynes, S.

2012-12-01

The NOAA Ship Okeanos Explorer, America's first Federal ship dedicated to ocean exploration, is envisioned as the ship upon which learners of all ages embark together on scientific voyages of exploration to poorly-known or unexplored areas of the global ocean. Through a combination of lessons, web pages, a ship tracker and dynamic imagery and video, learners participate as ocean explorers in breakthrough discoveries leading to increased scientific understanding and enhanced literacy about our ocean world. The Okeanos Explorer Education Materials Collection was developed to encourage educators and students to become personally involved with the ship's voyages and discoveries. This collection is presented in two volumes: Volume 1: Why Do We Explore? (modern reasons for ocean exploration - specifically, climate change, energy, human health and ocean health) and Volume 2: How Do We Explore? (21st Century strategies and tools for ocean exploration, including telepresence, sonar mapping, water column exploration and remotely operated vehicles). These volumes have been developed into full-day professional development opportunities provided at NOAA OER Alliance Partner sites nationwide and include lessons for grades 5-12 designed to support the evolving science education needs currently articulated in the K-12 Framework for Science Education. Together, the lessons, web pages, ship tracker and videos provide a dynamic education package for teachers to share modern ocean exploration in the classroom and inspire the next generation of explorers. This presentation will share these two Volumes, highlights from current explorations of the Okeanos Explorer and how they are used in ocean explorer lessons, and methods for accessing ocean explorer resources and following along with expeditions.;

Virtual Observatories, Data Mining, and Astroinformatics

NASA Astrophysics Data System (ADS)

Borne, Kirk

The historical, current, and future trends in knowledge discovery from data in astronomy are presented here. The story begins with a brief history of data gathering and data organization. A description of the development ofnew information science technologies for astronomical discovery is then presented. Among these are e-Science and the virtual observatory, with its data discovery, access, display, and integration protocols; astroinformatics and data mining for exploratory data analysis, information extraction, and knowledge discovery from distributed data collections; new sky surveys' databases, including rich multivariate observational parameter sets for large numbers of objects; and the emerging discipline of data-oriented astronomical research, called astroinformatics. Astroinformatics is described as the fourth paradigm of astronomical research, following the three traditional research methodologies: observation, theory, and computation/modeling. Astroinformatics research areas include machine learning, data mining, visualization, statistics, semantic science, and scientific data management.Each of these areas is now an active research discipline, with significantscience-enabling applications in astronomy. Research challenges and sample research scenarios are presented in these areas, in addition to sample algorithms for data-oriented research. These information science technologies enable scientific knowledge discovery from the increasingly large and complex data collections in astronomy. The education and training of the modern astronomy student must consequently include skill development in these areas, whose practitioners have traditionally been limited to applied mathematicians, computer scientists, and statisticians. Modern astronomical researchers must cross these traditional discipline boundaries, thereby borrowing the best of breed methodologies from multiple disciplines. In the era of large sky surveys and numerous large telescopes, the potential for astronomical discovery is equally large, and so the data-oriented research methods, algorithms, and techniques that are presented here will enable the greatest discovery potential from the ever-growing data and information resources in astronomy.

International cooperation is an essential component of modern scientific research and societal advancement [see Ismail-Zadeh and Beer, 2009], and scientific ocean drilling represents one of Earth science's longest-running and most successful international collaborations. The strength of this collaboration and its continued success result from the realization that scientific ocean drilling provides a unique and powerful tool to study the critical processes of both short-term change and the long-term evolution of Earth systems. A record of Earth's changing tectonics, climate, ocean circulation, and biota is preserved in marine sedimentary deposits and the underlying basement rocks. And because the ocean floor is the natural site for accumulation and preservation of geological materials, it may preserve a continuous record of these processes.

Experiments: Why and How?

PubMed

Hansson, Sven Ove

2016-06-01

An experiment, in the standard scientific sense of the term, is a procedure in which some object of study is subjected to interventions (manipulations) that aim at obtaining a predictable outcome or at least predictable aspects of the outcome. The distinction between an experiment and a non-experimental observation is important since they are tailored to different epistemic needs. Experimentation has its origin in pre-scientific technological experiments that were undertaken in order to find the best technological means to achieve chosen ends. Important parts of the methodological arsenal of modern experimental science can be traced back to this pre-scientific, technological tradition. It is claimed that experimentation involves a unique combination of acting and observing, a combination whose unique epistemological properties have not yet been fully clarified.

Russian, Soviet, and post-Soviet scientific migration: history and patterns

Kojevnikov, Alexei

2011-03-01

Immigrant scientists from other European countries (predominantly German) were crucial in establishing the tradition of modern science in the Russian Empire of the 18th and 19th centuries. Since the 1860s, however, outgoing waves of scientific migration started originating in Russia, bringing important innovations to international science. The scale and patterns of migration varied greatly with the turbulent time. The talk will describe several landmark stages of the proceess and their cultural consequences: from opening higher education possibilities for women during the late 19th century, to post-1917 academic refugees and Soviet defectors, to the 1960s brain drain provoked by the launch of Sputnik, and to what can be called the first truly global scientific diaspora of Russophone scientists after 1990.

Aesthetic Physics Education: A Symmetry Based, Physics and Fine Arts Curriculum

Physics education research in the past two decades has focused almost entirely on pedagogical methods, but the curriculum content remains unchanged. In a recent editorial in Physics Today (July, 2006, p. 10) the ability of physicists to “imagine new realities” is correlated with what are traditionally considered non-scientific skills, including imagination and creativity, qualities which are usually associated with fine arts. In view of the new developments in physics of the 21st Century, the importance of developing creativity and imagination through education is gaining recognition. We are investigating the effectiveness of teaching introductory physics from the viewpoint of symmetry, including the foundations of General Relativity and modern cosmology, without the need for the full tensor treatment. We will pilot a new course at UCSB in Winter Quarter, 2007 entitled Symmetry and Aesthetics in Introductory Physics. Our pedagogical model is based on three premises: that the introductory curriculum needs to be modernized; that mathematics should be presented as a language; and that theoretical physics has, at its core, a great deal in common with music, art, and dance. In this talk we will present the contents of our new course, and the means by which we plan to evaluate it in comparison to “regular” introductory courses. It is our hope that this modernized and integrated approach to introductory physics can also serve as a course for future teachers of primary and secondary school. This work is supported by NASA grant #20070268 and the Planck Explorer Mission.

Sir William Petty: modern epidemiologist (1623-1687).

PubMed

Banta, J E

1987-01-01

William Petty, physician, epidemiologist, political economist, demographer, cartographer, and administrator was an intellectual product of the seventeenth century. Petty was born in the year 1623 in Romsey, England of lower middle class parents; however, by the time of his death in 1687 he had become a knight of the realm, founder of the Royal Society, and friend of kings. Petty's life reflected the northern renaissance which induced such dramatic changes in science, technology, politics, and entrepreneurship. His education was eclectic, nonetheless he took his Doctor of Physic degree from Oxford in 1649 and became an Oxford don, where he spent the next few years as an academic before undertaking a definitive survey of Ireland on behalf of the Cromwell government. Ireland changed Petty's destiny and he became a man of the world and entrepreneur which stimulated his interest in public policy formulation and economics. It was Petty's peculiar genius to be innovative in the application of measurement, statistics, and mathematics to socioeconomic and demographic phenomena. As a physician he related his knowledge of health and disease to these phenomena in what in the modern context would be called human ecology or social epidemiology. These relationships and their measurement were employed to establish an objective set of data which could be analyzed for the purpose of rational public policy planning by the state. This scientific approach to public policy places Petty squarely in the context of modern epidemiologic and public health practice and marks the initiation of a major use of the epidemiologic method.

This study aimed to determine modern contraceptive prevalence and the barriers to using modern contraceptive methods among the couples in Dibindi health zone, Mbuji-Mayi, in the Democratic Republic of the Congo. We conducted a cross-sectional descriptive study from May to June 2015. Nonpregnant married women aged 15-49 years old at the time of the investigation, living in Dibindi health zone for two years and having freely consented to participate in the study were included. Data were collected by open-ended interview of these women. Modern contraceptive prevalence was referred to women who were currently using, at the time of the investigation, modern contraceptives. The comparison between proportions was performed at the significance threshold of 5%. Bonferroni's test was used to compare, two by two, the proportions of barriers to using modern contraceptive methods. Modern contraceptive prevalence in Dibindi was 18.4% in 2015. It was low with regard to family planning services available in this health zone. Several women refused to use modern contraceptive methods despite available information because of their desire for motherhood, religious prohibition, opposition on the part of their husband and fear of side effects. Sufficient client-centered or couple-centered information and family planning information should be strengthened in order to eliminate the false beliefs and to increase the use of modern contraceptive methods.

Objective To elucidate the connections between balneology and rheumatology in the founding period of the discipline of rheumatology, and describe the contributions of Max Hirsch, MD in the formation of professional rheumatology societies. Material and Methods Historical documents from the medical history collection of Vogelsang–Gommern, Germany, and original personal documents of the Hirsch family and information from the medical and historical period literature were used in developing this report. Results The first efforts at organizing rheumatology as a recognized clinical and academic discipline took place in the 1920s. Many of the first proponents were balneologists who cared for patients with chronic arthritic conditions without the benefit of effective medications. Max Hirsch, MD was a major figure in the development of modern rheumatology as it emerged from the provenance of balneology and orthopedics as a recognized organized medical discipline, contributing to the founding of the German Society for Rheumatology and the International League Against Rheumatism. Conclusion Max Hirsch made significant contributions to scientific and organized rheumatology in the early days of the discipline. His contributions to the field and his fate as a Jewish physician have only recently come to light. PMID:27733939

For the development of national heaIth care it is required to implement modern and effective methods and forms of governance. It is necessary to clearly identify transition to process management followed by an introduction of quality management care. It is necessary to create a complete version of the three-level health care system based on the integration into the system "Clinic - Hospital - Rehabilitation", which will ensure resource conservation in general throughout the industry. The most important task is purposeful comprehensive management training for health care--statesmen who have the potential ability to manage. The leader must possess all forms of management and apply them on a scientific basis. Standards and other tools of health management should constantly improve. Standards should be a teaching tool and help to improve the quality and effectiveness of treatment processes, the transition to the single-channel financing--the most advanced form of payment for the medical assistance. This type of financing requires managers to new management approaches, knowledge of business economics. One of the breakthrough objectives is the creation of a new type of health care organizations, which as lead locomotives for a rest.

Writings on Physics and Philosophy

NASA Astrophysics Data System (ADS)

Pauli, Wolfgang Enz, Charles P.; Meyenn, Karl V.

Like Bohr, Einstein and Heisenberg, Wolfgang Pauli was not only a Nobel laureate and one of the creators of modern physics, but also an eminent philosopher of modern science. This is the first book in English to include all his famous articles on physics and epistemology. They were actually translated during Pauli's lifetime by R. Schlapp and are now edited and annotated by Pauli's former assistant Ch. Enz. Pauli writes about the philosophical significance of complementarity, about space,time and causality, symmetry and the exclusion principle, but also about therole of the unconscious in modern science. His famous article on Kepler is included as well as many historical essays on Bohr, Ehrenfest,and Einstein as well as on the influence of the unconscious on scientific theories. The book addresses not only physicists, philosophers and historians of science, but also the general public.

Carlo Moreschi (1876-1921) was founding co-editor of the journal "Il Lavoro" (now known as "La Medicina del Lavoro"), together with Luigi Devoto in 1901. Despite this fact, many of his pioneering contributions to 20th century scientific debate are not well known outside Italy. The aim of this paper therefore was to recall Moreschi' achievements and the groundbreaking work of this remarkable Italian physician. A comprehensive analysis was conducted on scientific papers written by Carlo Moreschi between 1901 and 1920, extending the investigation to his original manuscripts and private correspondence with family and colleagues. Careful examination of Moreschi's work reveals several studies in the field of social medicine, epidemiology of infectious diseases, general pathology and oncology. In particular, his main interest in haematology and immunology enabled Moreschi to be one of the first to understand the mechanisms of complement fixation and the formation pathways ofantiglobulin sera. In this manner, Moreschi significantly contributed to the work of Wassermann regarding the diagnosis of syphilis, as well as contributing to the discovery of the "antiglobulin test", first described by Coombs in 1945. Furthermore, Moreschi co-founded "Il Lavoro" and "Haematologica", the oldest journals in their respective fields. According to Devoto, Moreschi can be remembered as the archetype modern researcher and clinician. His role in the 20th century scientific debate and his pioneering work in the field of immunology and haematology, that are often forgotten due to his premature death, deserve to be reconsidered and re-assessed by the Italian and international scientific community.

Concept analysis and the building blocks of theory: misconceptions regarding theory development.

The purpose of this article is to discuss the attempts to justify concepts analysis as a way to construct theory - a notion often advocated in nursing. The notion that concepts are the building blocks or threads from which theory is constructed is often repeated. It can be found in many articles and well-known textbooks. However, this notion is seldom explained or defended. The notion of concepts as building blocks has also been questioned by several authors. However, most of these authors seem to agree to some degree that concepts are essential components from which theory is built. Discussion paper. Literature was reviewed to synthesize and debate current knowledge. Our point is that theory is not built by concepts analysis or clarification and we will show that this notion has its basis in some serious misunderstandings. We argue that concept analysis is not a part of sound scientific method and should be abandoned. The current methods of concept analysis in nursing have no foundation in philosophy of science or in language philosophy. The type of concept analysis performed in nursing is not a way to 'construct' theory. Rather, theories are formed by creative endeavour to propose a solution to a scientific and/or practical problem. The bottom line is that the current style and form of concept analysis in nursing should be abandoned in favour of methods in line with modern theory of science. © 2016 John Wiley & Sons Ltd.

Gene Patents and Personalized Cancer Care: Impact of the Myriad Case on Clinical Oncology

Genomic discoveries have transformed the practice of oncology and cancer prevention. Diagnostic and therapeutic advances based on cancer genomics developed during a time when it was possible to patent genes. A case before the Supreme Court, Association for Molecular Pathology v Myriad Genetics, Inc seeks to overturn patents on isolated genes. Although the outcomes are uncertain, it is suggested here that the Supreme Court decision will have few immediate effects on oncology practice or research but may have more significant long-term impact. The Federal Circuit court has already rejected Myriad's broad diagnostic methods claims, and this is not affected by the Supreme Court decision. Isolated DNA patents were already becoming obsolete on scientific grounds, in an era when human DNA sequence is public knowledge and because modern methods of next-generation sequencing need not involve isolated DNA. The Association for Molecular Pathology v Myriad Supreme Court decision will have limited impact on new drug development, as new drug patents usually involve cellular methods. A nuanced Supreme Court decision acknowledging the scientific distinction between synthetic cDNA and genomic DNA will further mitigate any adverse impact. A Supreme Court decision to include or exclude all types of DNA from patent eligibility could impact future incentives for genomic discovery as well as the future delivery of medical care. Whatever the outcome of this important case, it is important that judicial and legislative actions in this area maximize genomic discovery while also ensuring patients' access to personalized cancer care.

Causal criteria and counterfactuals; nothing more (or less) than scientific common sense.

Phillips, Carl V; Goodman, Karen J

Two persistent myths in epidemiology are that we can use a list of "causal criteria" to provide an algorithmic approach to inferring causation and that a modern "counterfactual model" can assist in the same endeavor. We argue that these are neither criteria nor a model, but that lists of causal considerations and formalizations of the counterfactual definition of causation are nevertheless useful tools for promoting scientific thinking. They set us on the path to the common sense of scientific inquiry, including testing hypotheses (really putting them to a test, not just calculating simplistic statistics), responding to the Duhem-Quine problem, and avoiding many common errors. Austin Bradford Hill's famous considerations are thus both over-interpreted by those who would use them as criteria and under-appreciated by those who dismiss them as flawed. Similarly, formalizations of counterfactuals are under-appreciated as lessons in basic scientific thinking. The need for lessons in scientific common sense is great in epidemiology, which is taught largely as an engineering discipline and practiced largely as technical tasks, making attention to core principles of scientific inquiry woefully rare.

Modern scientific datasets present numerous data management and analysis challenges. State-of-the-art index and query technologies such as FastBit are critical for facilitating interactive exploration of large datasets. These technologies rely on adding auxiliary information to existing datasets to accelerate query processing. To use these indices, we need to match the relational data model used by the indexing systems with the array data model used by most scientific data, and to provide an efficient input and output layer for reading and writing the indices. In this work, we present a flexible design that can be easily applied to most scientific datamore » formats. We demonstrate this flexibility by applying it to two of the most commonly used scientific data formats, HDF5 and NetCDF. We present two case studies using simulation data from the particle accelerator and climate simulation communities. To demonstrate the effectiveness of the new design, we also present a detailed performance study using both synthetic and real scientific workloads.« less

Use and mis-use of supplementary material in science publications.

PubMed

Pop, Mihai; Salzberg, Steven L

Supplementary material is a ubiquitous feature of scientific articles, particularly in journals that limit the length of the articles. While the judicious use of supplementary material can improve the readability of scientific articles, its excessive use threatens the scientific review process and by extension the integrity of the scientific literature. In many cases supplementary material today is so extensive that it is reviewed superficially or not at all. Furthermore, citations buried within supplementary files rob other scientists of recognition of their contribution to the scientific record. These issues are exacerbated by the lack of guidance on the use of supplementary information from the journals to authors and reviewers. We propose that the removal of artificial length restrictions plus the use of interactive features made possible by modern electronic media can help to alleviate these problems. Many journals, in fact, have already removed article length limitations (as is the case for BMC Bioinformatics and other BioMed Central journals). We hope that the issues raised in our article will encourage publishers and scientists to work together towards a better use of supplementary information in scientific publishing.

Magic, science and masculinity: marketing toy chemistry sets.

PubMed

Al-Gailani, Salim

2009-12-01

At least since the late nineteenth century, toy chemistry sets have featured in standard scripts of the achievement of eminence in science, and they remain important in constructions of scientific identity. Using a selection of these toys manufactured in Britain and the United States, and with particular reference to the two dominant American brands, Gilbert and Chemcraft, this paper suggests that early twentieth-century chemistry sets were rooted in overlapping Victorian traditions of entertainment magic and scientific recreations. As chemistry set marketing copy gradually reoriented towards emphasising scientific modernity, citizenship, discipline and educational value, pre-twentieth-century traditions were subsumed within domestic-and specifically masculine-tropes. These developments in branding strategies point to transformations in both users' engagement with their chemistry sets and the role of scientific toys in domestic play. The chemistry set serves here as a useful tool for measuring cultural change and lay engagement with chemistry.

Observability, Anschaulichkeit and Abstraction: A Journey into Werner Heisenberg's Science and Philosophy

Werner Heisenberg was one of the greatest physicists of the 20th century. He participated as a front rank actor in the shaping of a good part of XXth century physics and directly witnessed most of the intellectual struggles which led to what he called “Wandlungen in den Grundlagen der exakten Naturwissenschaft”. This expression is borrowed from one of the many talks and writings he devoted to the analysis of the scientific and philosophical implications of his, and his fellows physicists, findings. Indeed, Heisenberg's scientific activity increasingly reflected his more general intellectual views. This makes him another magnificent representative of a glorious linage going from the remote times of modern science to Einstein, Bohr and the like. This “philosophical” vein started early in his scientific life, and got stronger with time, prompted by the highly demanding scientific, but also social and political context of his mature years.

Scientific travel in the Atlantic world: the French expedition to Gorée and the Antilles, 1681-1683.

Although historians have long recognized the importance of long-range scientific expeditions in both the practice and culture of eighteenth- and nineteenth-century science, it is less well understood how this form of scientific organization emerged and became established in the seventeenth and early eighteenth centuries. In the late seventeenth century new European scientific institutions tried to make use of globalized trade networks for their own ends, but to do so proved difficult. This paper offers a case history of one such expedition, the voyage sponsored by the French Académie royale des sciences to Gorée (in modern Senegal) and the Caribbean islands of Guadeloupe and Martinique in 1681-3. The voyage of Varin, Deshayes and de Glos reveals how the process of travel itself caused problems for instruments and observers alike.
