Exploring the Changes in Students' Understanding of the Scientific Method Using Word Associations

NASA Astrophysics Data System (ADS)

Gulacar, Ozcan; Sinan, Olcay; Bowman, Charles R.; Yildirim, Yetkin

2015-10-01

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

Background: Reading scientific literature is mandatory for researchers and clinicians. With an overflow of medical and dental journals, it is essential to develop a method to choose and read the right articles. Objective: To outline a logical and orderly approach to reading a scientific manuscript. By breaking down the task into smaller, step-by-step components, one should be able to attain the skills to read a scientific article with ease. Methods: The reader should begin by reading the title, abstract and conclusions first. If a decision is made to read the entire article, the key elements of the article can be perused in a systematic manner effectively and efficiently. A cogent and organized method is presented to read articles published in scientific journals. Conclusion: One can read and appreciate a scientific manuscript if a systematic approach is followed in a simple and logical manner. PMID:23798833

Relationship between scientific knowledge and fortune-telling.

PubMed

Shein, Paichi Pat; Li, Yuh-Yuh; Huang, Tai-Chu

2014-10-01

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

Conceptions of Good Science in Our Data-Rich World.

Elliott, Kevin C; Cheruvelil, Kendra S; Montgomery, Georgina M; Soranno, Patricia A

2016-10-01

Scientists have been debating for centuries the nature of proper scientific methods. Currently, criticisms being thrown at data-intensive science are reinvigorating these debates. However, many of these criticisms represent long-standing conflicts over the role of hypothesis testing in science and not just a dispute about the amount of data used. Here, we show that an iterative account of scientific methods developed by historians and philosophers of science can help make sense of data-intensive scientific practices and suggest more effective ways to evaluate this research. We use case studies of Darwin's research on evolution by natural selection and modern-day research on macrosystems ecology to illustrate this account of scientific methods and the innovative approaches to scientific evaluation that it encourages. We point out recent changes in the spheres of science funding, publishing, and education that reflect this richer account of scientific practice, and we propose additional reforms.

Highly comparative time-series analysis: the empirical structure of time series and their methods.

Fulcher, Ben D; Little, Max A; Jones, Nick S

2013-06-06

The process of collecting and organizing sets of observations represents a common theme throughout the history of science. However, despite the ubiquity of scientists measuring, recording and analysing the dynamics of different processes, an extensive organization of scientific time-series data and analysis methods has never been performed. Addressing this, annotated collections of over 35 000 real-world and model-generated time series, and over 9000 time-series analysis algorithms are analysed in this work. We introduce reduced representations of both time series, in terms of their properties measured by diverse scientific methods, and of time-series analysis methods, in terms of their behaviour on empirical time series, and use them to organize these interdisciplinary resources. This new approach to comparing across diverse scientific data and methods allows us to organize time-series datasets automatically according to their properties, retrieve alternatives to particular analysis methods developed in other scientific disciplines and automate the selection of useful methods for time-series classification and regression tasks. The broad scientific utility of these tools is demonstrated on datasets of electroencephalograms, self-affine time series, heartbeat intervals, speech signals and others, in each case contributing novel analysis techniques to the existing literature. Highly comparative techniques that compare across an interdisciplinary literature can thus be used to guide more focused research in time-series analysis for applications across the scientific disciplines.

Visual Display of Scientific Studies, Methods, and Results

Saltus, R. W.; Fedi, M.

2015-12-01

The need for efficient and effective communication of scientific ideas becomes more urgent each year.A growing number of societal and economic issues are tied to matters of science - e.g., climate change, natural resource availability, and public health. Societal and political debate should be grounded in a general understanding of scientific work in relevant fields. It is difficult for many participants in these debates to access science directly because the formal method for scientific documentation and dissemination is the journal paper, generally written for a highly technical and specialized audience. Journal papers are very effective and important for documentation of scientific results and are essential to the requirements of science to produce citable and repeatable results. However, journal papers are not effective at providing a quick and intuitive summary useful for public debate. Just as quantitative data are generally best viewed in graphic form, we propose that scientific studies also can benefit from visual summary and display. We explore the use of existing methods for diagramming logical connections and dependencies, such as Venn diagrams, mind maps, flow charts, etc., for rapidly and intuitively communicating the methods and results of scientific studies. We also discuss a method, specifically tailored to summarizing scientific papers that we introduced last year at AGU. Our method diagrams the relative importance and connections between data, methods/models, results/ideas, and implications/importance using a single-page format with connected elements in these four categories. Within each category (e.g., data) the spatial location of individual elements (e.g., seismic, topographic, gravity) indicates relative novelty (e.g., are these new data?) and importance (e.g., how critical are these data to the results of the paper?). The goal is to find ways to rapidly and intuitively share both the results and the process of science, both for communication between scientists and for communication more generally between scientists and other non-scientists.

Computational Simulations and the Scientific Method

NASA Technical Reports Server (NTRS)

Kleb, Bil; Wood, Bill

2005-01-01

As scientific simulation software becomes more complicated, the scientific-software implementor's need for component tests from new model developers becomes more crucial. The community's ability to follow the basic premise of the Scientific Method requires independently repeatable experiments, and model innovators are in the best position to create these test fixtures. Scientific software developers also need to quickly judge the value of the new model, i.e., its cost-to-benefit ratio in terms of gains provided by the new model and implementation risks such as cost, time, and quality. This paper asks two questions. The first is whether other scientific software developers would find published component tests useful, and the second is whether model innovators think publishing test fixtures is a feasible approach.

A science confidence gap: Education, trust in scientific methods, and trust in scientific institutions in the United States, 2014.

PubMed

Achterberg, Peter; de Koster, Willem; van der Waal, Jeroen

2017-08-01

Following up on suggestions that attitudes toward science are multi-dimensional, we analyze nationally representative survey data collected in the United States in 2014 ( N = 2006), and demonstrate the existence of a science confidence gap: some people place great trust in scientific methods and principles, but simultaneously distrust scientific institutions. This science confidence gap is strongly associated with level of education: it is larger among the less educated than among the more educated. We investigate explanations for these educational differences. Whereas hypotheses deduced from reflexive-modernization theory do not pass the test, those derived from theorizing on the role of anomie are corroborated. The less educated are more anomic (they have more modernity-induced cultural discontents), which not only underlies their distrust in scientific institutions, but also fuels their trust in scientific methods and principles. This explains why this science confidence gap is most pronounced among the less educated.

Professors John Cotton and Randall Scalise illustrate these principles using a series of examples and demonstrations that is enlightening, educational, and entertaining. This lecture/demonstration features highlights from their course (whose unofficial title is ``debunking pseudoscience'' ) which enables students to detect pseudoscience in its many guises: paranormal phenomena, free-energy devices, alternative medicine, and many others.

Being scientifical: Popularity, purpose and promotion of amateur research and investigation groups in the U.S

NASA Astrophysics Data System (ADS)

Hill, Sharon A.

21st century television and the Internet are awash in content regarding amateur paranormal investigators and research groups. These groups proliferated after reality investigation programs appeared on television. Exactly how many groups are active in the U.S. at any time is not known. The Internet provides an ideal means for people with niche interests to find each other and organize activities. This study collected information from 1000 websites of amateur research and investigation groups (ARIGs) to determine their location, area of inquiry, methodology and, particularly, to determine if they state that they use science as part of their mission, methods or goals. 57.3% of the ARIGs examined specifically noted or suggested use of science as part of the groups' approach to investigation and research. Even when not explicit, ARIGs often used science-like language, symbols and methods to describe their groups' views or activities. Yet, non-scientific and subjective methods were described as employed in conjunction with objective methods. Furthermore, what were considered scientific processes by ARIGs did not match with established methods and the ethos of the scientific research community or scientific processes of investigation. ARIGs failed to display fundamental understanding regarding objectivity, methodological naturalism, peer review, critical thought and theoretical plausibility. The processes of science appear to be mimicked to present a serious and credible reputation to the non-scientific public. These processes are also actively promoted in the media and directly to the local public as "scientific". These results highlight the gap between the scientific community and the lay public regarding the understanding of what it means to do science and what criteria are necessary to establish reliable knowledge about the world.

Where do Students Go Wrong in Applying the Scientific Method?

NASA Astrophysics Data System (ADS)

Rubbo, Louis; Moore, Christopher

2015-04-01

Non-science majors completing a liberal arts degree are frequently required to take a science course. Ideally with the completion of a required science course, liberal arts students should demonstrate an improved capability in the application of the scientific method. In previous work we have demonstrated that this is possible if explicit instruction is spent on the development of scientific reasoning skills. However, even with explicit instruction, students still struggle to apply the scientific process. Counter to our expectations, the difficulty is not isolated to a single issue such as stating a testable hypothesis, designing an experiment, or arriving at a supported conclusion. Instead students appear to struggle with every step in the process. This talk summarizes our work looking at and identifying where students struggle in the application of the scientific method. This material is based upon work supported by the National Science Foundation under Grant No. 1244801.

An evidence-based patient-centered method makes the biopsychosocial model scientific.

PubMed

Smith, Robert C; Fortin, Auguste H; Dwamena, Francesca; Frankel, Richard M

2013-06-01

To review the scientific status of the biopsychosocial (BPS) model and to propose a way to improve it. Engel's BPS model added patients' psychological and social health concerns to the highly successful biomedical model. He proposed that the BPS model could make medicine more scientific, but its use in education, clinical care, and, especially, research remains minimal. Many aver correctly that the present model cannot be defined in a consistent way for the individual patient, making it untestable and non-scientific. This stems from not obtaining relevant BPS data systematically, where one interviewer obtains the same information another would. Recent research by two of the authors has produced similar patient-centered interviewing methods that are repeatable and elicit just the relevant patient information needed to define the model at each visit. We propose that the field adopt these evidence-based methods as the standard for identifying the BPS model. Identifying a scientific BPS model in each patient with an agreed-upon, evidence-based patient-centered interviewing method can produce a quantum leap ahead in both research and teaching. A scientific BPS model can give us more confidence in being humanistic. In research, we can conduct more rigorous studies to inform better practices. Copyright © 2013 Elsevier Ireland Ltd.

Creativity is a fundamental and remarkable human capacity, yet the scientific study of creativity has been limited by the difficulty of reconciling the scientific method and creative processes. We outline several hurdles and considerations that should be addressed when studying the cognitive neuroscience of creativity and suggest that jazz improvisation may be one of the most useful experimental models for the study of spontaneous creativity. More broadly, we argue that studying creativity in a way that is both scientifically and ecologically valid requires collaboration between neuroscientists and artists. © 2013 New York Academy of Sciences.

Design and Implementation of Scientific Software Components to Enable Multiscale Modeling: The Effective Fragment Potential (QM/EFP) Method

DOE Office of Scientific and Technical Information (OSTI.GOV)

Gaenko, Alexander; Windus, Theresa L.; Sosonkina, Masha

2012-10-19

The design and development of scientific software components to provide an interface to the effective fragment potential (EFP) methods are reported. Multiscale modeling of physical and chemical phenomena demands the merging of software packages developed by research groups in significantly different fields. Componentization offers an efficient way to realize new high performance scientific methods by combining the best models available in different software packages without a need for package readaptation after the initial componentization is complete. The EFP method is an efficient electronic structure theory based model potential that is suitable for predictive modeling of intermolecular interactions in large molecularmore » systems, such as liquids, proteins, atmospheric aerosols, and nanoparticles, with an accuracy that is comparable to that of correlated ab initio methods. The developed components make the EFP functionality accessible for any scientific component-aware software package. The performance of the component is demonstrated on a protein interaction model, and its accuracy is compared with results obtained with coupled cluster methods.« less

Teaching Scientific Reasoning to Liberal Arts Students

NASA Astrophysics Data System (ADS)

Rubbo, Louis

2014-03-01

University courses in conceptual physics and astronomy typically serve as the terminal science experience for the liberal arts student. Within this population significant content knowledge gains can be achieved by utilizing research verified pedagogical methods. However, from the standpoint of the Univeristy, students are expected to complete these courses not necessarily for the content knowledge but instead for the development of scientific reasoning skills. Results from physics education studies indicate that unless scientific reasoning instruction is made explicit students do not progress in their reasoning abilities. How do we complement the successful content based pedagogical methods with instruction that explicitly focuses on the development of scientific reasoning skills? This talk will explore methodologies that actively engages the non-science students with the explicit intent of fostering their scientific reasoning abilities.

Optical methods in nano-biotechnology

Bruno, Luigi; Gentile, Francesco

2016-01-01

A scientific theory is not a mathematical paradigm. It is a framework that explains natural facts and may predict future observations. A scientific theory may be modified, improved, or rejected. Science is less a collection of theories and more the process that brings either to deny some hypothesis, maintain or accept somehow universal beliefs (or disbeliefs), and create new models that may improve or replace precedent theories. This process cannot be entrusted to common sense, personal experiences or anecdotes (many precepts in physics are indeed counterintuitive), but on a rigorous design, observation and rational to statistical analysis of new experiments. Scientific results are always provisional: scientists rarely proclaim an absolute truth or absolute certainty. Uncertainty is inevitable at the frontiers of knowledge. Notably, this is the definition of the scientific method and what we have written in the above echoes the opinion Marcia McNutt who is the Editor of Science 'Science is a method for deciding whether what we choose to believe has a basis in the laws of nature or not'. A new discovery, a new theory that explains that discovery and the scientific method itself need observations, verifications and are susceptible of falsification.

Using Rubrics as a Scientific Writing Instructional Method in Early Stage Undergraduate Neuroscience Study.

PubMed

Clabough, Erin B D; Clabough, Seth W

2016-01-01

Scientific writing is an important communication and learning tool in neuroscience, yet it is a skill not adequately cultivated in introductory undergraduate science courses. Proficient, confident scientific writers are produced by providing specific knowledge about the writing process, combined with a clear student understanding about how to think about writing (also known as metacognition). We developed a rubric for evaluating scientific papers and assessed different methods of using the rubric in inquiry-based introductory biology classrooms. Students were either 1) given the rubric alone, 2) given the rubric, but also required to visit a biology subject tutor for paper assistance, or 3) asked to self-grade paper components using the rubric. Students who were required to use a peer tutor had more negative attitudes towards scientific writing, while students who used the rubric alone reported more confidence in their science writing skills by the conclusion of the semester. Overall, students rated the use of an example paper or grading rubric as the most effective ways of teaching scientific writing, while rating peer review as ineffective. Our paper describes a concrete, simple method of infusing scientific writing into inquiry-based science classes, and provides clear avenues to enhance communication and scientific writing skills in entry-level classes through the use of a rubric or example paper, with the goal of producing students capable of performing at a higher level in upper level neuroscience classes and independent research.

The weakness of scientific ability of students in college has been being a concern in this case, especially in terms of laboratory activities to support Laboratory Based Education. Scientific ability is a basic ability that must be dominated by students in basic physics lecturing process as a part of scientific method. This research aims to explore the indicators emergence of the scientific ability of students in Chemistry Education of Study Program, Faculty of Teaching and Education University of Palangka Raya through Inquiry Based Learning in basic physics courses. This research is a quantitative research by using descriptive method (descriptive-quantitative). Students are divided into three categories of group those are excellent group, low group, and heterogeneous group. The result shows that the excellent group and low group have same case that were occured decreasing in the percentage of achievement of scientific ability, while in heterogeneous group was increased. The differentiation of these results are caused by enthusiastic level of students in every group that can be seen in tables of scientific ability achievement aspects. By the results of this research, hoping in the future can be a references for further research about innovative learning strategies and models that can improve scientific ability and scientific reasoning especially for science teacher candidates.

Unproven methods in cancer treatment.

Hauser, S P

1993-07-01

The nature-based and nontoxic image makes application of unproven methods in oncology attractive in contrast to application of a mechanized scientific medicine. The application frequency of these treatments ranges from 10% to greater than 60%. Increasingly, the promoters try to create a scientific impression through a pseudologic cancer theory, a harmless diagnostic test, and a holistic treatment of every cancer. Of the big variety of unproven methods, which are summarized in 11 groups in this review, the following are discussed: anthroposophic and other mistletoe preparations; homeopathy; Maharishi Ayur-Veda; unproven anticancer diets; orthomolecular medicine, including ascorbic acid; and methods supposedly stimulating unspecific and specific defense mechanisms. In conclusion, physicians should beware of and have knowledge of currently used unproven cancer treatments for epidemiologic, social, economic, and scientific reasons.

Predicting future discoveries from current scientific literature.

Petrič, Ingrid; Cestnik, Bojan

2014-01-01

Knowledge discovery in biomedicine is a time-consuming process starting from the basic research, through preclinical testing, towards possible clinical applications. Crossing of conceptual boundaries is often needed for groundbreaking biomedical research that generates highly inventive discoveries. We demonstrate the ability of a creative literature mining method to advance valuable new discoveries based on rare ideas from existing literature. When emerging ideas from scientific literature are put together as fragments of knowledge in a systematic way, they may lead to original, sometimes surprising, research findings. If enough scientific evidence is already published for the association of such findings, they can be considered as scientific hypotheses. In this chapter, we describe a method for the computer-aided generation of such hypotheses based on the existing scientific literature. Our literature-based discovery of NF-kappaB with its possible connections to autism was recently approved by scientific community, which confirms the ability of our literature mining methodology to accelerate future discoveries based on rare ideas from existing literature.

A philosophical examination of Mead's pragmatist constructivism as a referent for adult science education

NASA Astrophysics Data System (ADS)

Furbish, Dean Russel

The purpose of this study is to examine pragmatist constructivism as a science education referent for adult learners. Specifically, this study seeks to determine whether George Herbert Mead's doctrine, which conflates pragmatist learning theory and philosophy of natural science, might facilitate (a) scientific concept acquisition, (b) learning scientific methods, and (c) preparation of learners for careers in science and science-related areas. A philosophical examination of Mead's doctrine in light of these three criteria has determined that pragmatist constructivism is not a viable science education referent for adult learners. Mead's pragmatist constructivism does not portray scientific knowledge or scientific methods as they are understood by practicing scientists themselves, that is, according to scientific realism. Thus, employment of pragmatist constructivism does not adequately prepare future practitioners for careers in science-related areas. Mead's metaphysics does not allow him to commit to the existence of the unobservable objects of science such as molecular cellulose or mosquito-borne malarial parasites. Mead's anti-realist metaphysics also affects his conception of scientific methods. Because Mead does not commit existentially to the unobservable objects of realist science, Mead's science does not seek to determine what causal role if any the hypothetical objects that scientists routinely posit while theorizing might play in observable phenomena. Instead, constructivist pragmatism promotes subjective epistemology and instrumental methods. The implication for learning science is that students are encouraged to derive scientific concepts based on a combination of personal experience and personal meaningfulness. Contrary to pragmatist constructivism, however, scientific concepts do not arise inductively from subjective experience driven by personal interests. The broader implication of this study for adult education is that the philosophically laden claims of constructivist learning theories need to be identified and assessed independently of any empirical support that these learning theories might enjoy. This in turn calls for educational experiences for graduate students of education that incorporate philosophical understanding such that future educators might be able to recognize and weigh the philosophically laden claims of adult learning theories.

Scientific Misconduct.

PubMed

Gross, Charles

2016-01-01

Scientific misconduct has been defined as fabrication, falsification, and plagiarism. Scientific misconduct has occurred throughout the history of science. The US government began to take systematic interest in such misconduct in the 1980s. Since then, a number of studies have examined how frequently individual scientists have observed scientific misconduct or were involved in it. Although the studies vary considerably in their methodology and in the nature and size of their samples, in most studies at least 10% of the scientists sampled reported having observed scientific misconduct. In addition to studies of the incidence of scientific misconduct, this review considers the recent increase in paper retractions, the role of social media in scientific ethics, several instructional examples of egregious scientific misconduct, and potential methods to reduce research misconduct.

Scientific Process Flowchart Assessment (SPFA): A Method for Evaluating Changes in Understanding and Visualization of the Scientific Process in a Multidisciplinary Student Population

PubMed Central

Wilson, Kristy J.; Rigakos, Bessie

2016-01-01

The scientific process is nonlinear, unpredictable, and ongoing. Assessing the nature of science is difficult with methods that rely on Likert-scale or multiple-choice questions. This study evaluated conceptions about the scientific process using student-created visual representations that we term “flowcharts.” The methodology, Scientific Process Flowchart Assessment (SPFA), consisted of a prompt and rubric that was designed to assess students’ understanding of the scientific process. Forty flowcharts representing a multidisciplinary group without intervention and 26 flowcharts representing pre- and postinstruction were evaluated over five dimensions: connections, experimental design, reasons for doing science, nature of science, and interconnectivity. Pre to post flowcharts showed a statistically significant improvement in the number of items and ratings for the dimensions. Comparison of the terms used and connections between terms on student flowcharts revealed an enhanced and more nuanced understanding of the scientific process, especially in the areas of application to society and communication within the scientific community. We propose that SPFA can be used in a variety of circumstances, including in the determination of what curricula or interventions would be useful in a course or program, in the assessment of curriculum, or in the evaluation of students performing research projects.

Darwinism and positivism as methodological influences on the development of psychology.

PubMed

Mackenzie, B

1976-10-01

The methodological significance of evolutionary theory for psychology may be distinguished from its substantive or theoretical significance. The methodological significance was that evolutionay theory broadened the current conceptors of scientific method and rendered them relatively independent of physics. It thereby made the application of the "scientific method" to psychology much more feasible than it had been previously, and thus established the possibility of a wide-ranging scientific psychology for the first time. The methodological eclecticism that made scientific psychology possible did not, however, remain a feature of psychology for very long. Psychology's methodology rapidly became restricted and codified through the influence of, and in imitation of, the rigorously positivistic orientation of physics around the turn of the twentieth century.

Philosophy of science and the diagnostic process.

PubMed

Willis, Brian H; Beebee, Helen; Lasserson, Daniel S

2013-10-01

This is an overview of the principles that underpin philosophy of science and how they may provide a framework for the diagnostic process. Although philosophy dates back to antiquity, it is only more recently that philosophers have begun to enunciate the scientific method. Since Aristotle formulated deduction, other modes of reasoning including induction, inference to best explanation, falsificationism, theory-laden observations and Bayesian inference have emerged. Thus, rather than representing a single overriding dogma, the scientific method is a toolkit of ideas and principles of reasoning. Here we demonstrate that the diagnostic process is an example of science in action and is therefore subject to the principles encompassed by the scientific method. Although a number of the different forms of reasoning are used readily by clinicians in practice, without a clear understanding of their pitfalls and the assumptions on which they are based, it leaves doctors open to diagnostic error. We conclude by providing a case example from the medico-legal literature in which diagnostic errors were made, to illustrate how applying the scientific method may mitigate the chance for diagnostic error.

Evaluation of university scientific research ability based on the output of sci-tech papers: A D-AHP approach.

PubMed

Zong, Fan; Wang, Lifang

2017-01-01

University scientific research ability is an important indicator to express the strength of universities. In this paper, the evaluation of university scientific research ability is investigated based on the output of sci-tech papers. Four university alliances from North America, UK, Australia, and China, are selected as the case study of the university scientific research evaluation. Data coming from Thomson Reuters InCites are collected to support the evaluation. The work has contributed new framework to the issue of university scientific research ability evaluation. At first, we have established a hierarchical structure to show the factors that impact the evaluation of university scientific research ability. Then, a new MCDM method called D-AHP model is used to implement the evaluation and ranking of different university alliances, in which a data-driven approach is proposed to automatically generate the D numbers preference relations. Next, a sensitivity analysis has been given to show the impact of weights of factors and sub-factors on the evaluation result. At last, the results obtained by using different methods are compared and discussed to verify the effectiveness and reasonability of this study, and some suggestions are given to promote China's scientific research ability.

Misconduct versus honest error and scientific disagreement.

PubMed

Resnik, David B; Stewart, C Neal

2012-01-01

Researchers sometimes mistakenly accuse their peers of misconduct. It is important to distinguish between misconduct and honest error or a difference of scientific opinion to prevent unnecessary and time-consuming misconduct proceedings, protect scientists from harm, and avoid deterring researchers from using novel methods or proposing controversial hypotheses. While it is obvious to many researchers that misconduct is different from a scientific disagreement or simply an inadvertent mistake in methods, analysis or misinterpretation of data, applying this distinction to real cases is sometimes not easy. Because the line between misconduct and honest error or a scientific dispute is often unclear, research organizations and institutions should distinguish between misconduct and honest error and scientific disagreement in their policies and practices. These distinctions should also be explained during educational sessions on the responsible conduct of research and in the mentoring process. When researchers wrongfully accuse their peers of misconduct, it is important to help them understand the distinction between misconduct and honest error and differences of scientific judgment or opinion, pinpoint the source of disagreement, and identify the relevant scientific norms. They can be encouraged to settle the dispute through collegial discussion and dialogue, rather than a misconduct allegation.

Diagramming Scientific Papers - A New Idea for Understanding/Teaching/Sharing Science

NASA Astrophysics Data System (ADS)

Saltus, R. W.; Fedi, M.

2014-12-01

How do we best communicate scientific results? As the number of scientists and scientific papers steadily increases, one of the greatest challenges is effective and efficient sharing of science. The official repository of scientific knowledge is the peer-reviewed journal archive. However, this primary knowledge can be difficult to access and understand by anyone but a relevant specialist. We propose some new ideas for diagramming the content and significance of scientific papers using a simple and intuitive graphical approach. We propose a visual mapping that highlights four fundamental aspects of most scientific papers: Data, Methods/Models, Results/Ideas, and Implications/Importance. Each of these aspects is illustrated within boxed fields which contain one or more labeled elements positioned to reflect novelty (aka originality) and impact relative to the vertical and horizontal axes. The relative position of the boxed fields themselves indicates the relative significance of data, methods, ideas, or implications to the paper. Optional lines between boxed elements indicate the flow and dependence of data/methods/ideas within the paper. As with any graphical depiction, you need to see it to best appreciate it -- this written abstract is only meant as an introduction to the idea.We anticipate that diagramming may prove useful in both communication of scientific ideas among scientists as well as in education and outreach. For example, professors could assign diagramming of papers as a way to help students organize their thoughts about the structure and impact of scientific articles. Students could compare and defend their diagrams as a way to facilitate discussion/debate. Authors could diagram their own work as a way to efficiently summarize the importance and significance of their work. We also imagine that (in the future) automatic diagramming might be used to help summarize or facilitate the discovery of archived work.

Impact of Including Authentic Inquiry Experiences in Methods Courses for Pre-Service Secondary Teachers

NASA Astrophysics Data System (ADS)

Slater, T. F.; Elfring, L.; Novodvorsky, I.; Talanquer, V.; Quintenz, J.

2007-12-01

Science education reform documents universally call for students to have authentic and meaningful experiences using real data in the context of their science education. The underlying philosophical position is that students analyzing data can have experiences that mimic actual research. In short, research experiences that reflect the scientific spirit of inquiry potentially can: prepare students to address real world complex problems; develop students' ability to use scientific methods; prepare students to critically evaluate the validity of data or evidence and of the consequent interpretations or conclusions; teach quantitative skills, technical methods, and scientific concepts; increase verbal, written, and graphical communication skills; and train students in the values and ethics of working with scientific data. However, it is unclear what the broader pre-service teacher preparation community is doing in preparing future teachers to promote, manage, and successful facilitate their own students in conducting authentic scientific inquiry. Surveys of undergraduates in secondary science education programs suggests that students have had almost no experiences themselves in conducting open scientific inquiry where they develop researchable questions, design strategies to pursue evidence, and communicate data-based conclusions. In response, the College of Science Teacher Preparation Program at the University of Arizona requires all students enrolled in its various science teaching methods courses to complete an open inquiry research project and defend their findings at a specially designed inquiry science mini-conference at the end of the term. End-of-term surveys show that students enjoy their research experience and believe that this experience enhances their ability to facilitate their own future students in conducting open inquiry.

A generative model for scientific concept hierarchies.

PubMed

Datta, Srayan; Adar, Eytan

2018-01-01

In many scientific disciplines, each new 'product' of research (method, finding, artifact, etc.) is often built upon previous findings-leading to extension and branching of scientific concepts over time. We aim to understand the evolution of scientific concepts by placing them in phylogenetic hierarchies where scientific keyphrases from a large, longitudinal academic corpora are used as a proxy of scientific concepts. These hierarchies exhibit various important properties, including power-law degree distribution, power-law component size distribution, existence of a giant component and less probability of extending an older concept. We present a generative model based on preferential attachment to simulate the graphical and temporal properties of these hierarchies which helps us understand the underlying process behind scientific concept evolution and may be useful in simulating and predicting scientific evolution.

Heisenberg: Paralleling Scientific and Historical Methods

NASA Astrophysics Data System (ADS)

Cofield, Calla

2007-04-01

Werner Heisenberg is an important historical subject within the physics community partly because his actions as a human being are discussed nearly as often as his work as a physicist. But does the scientific community establish it's historical ideas with the same methods and standards as it's scientific conclusions? I interviewed Heisenberg's son, Jochen Heisenberg, a professor of physics at UNH. Despite a great amount of literature on Werner Heisenberg, only one historian has interviewed Jochen about his father and few have interviewed Werner's wife. Nature is mysterious and unpredictable, but it doesn't lie or distort like humans, and we believe it can give ``honest'' results. But are we keeping the same standards with history that we do with science? Are we holding historians to these standards and if not, is it up to scientists to not only be keepers of scientific understanding, but historical understanding as well? Shouldn't we record history by using the scientific method, by weighing the best sources of data differently than the less reliable, and are we right to be as stubborn about changing our views on history as we are about changing our views on nature?

Correcting Systemic Deficiencies in Our Scientific Infrastructure

PubMed Central

Doss, Mohan

2014-01-01

Scientific method is inherently self-correcting. When different hypotheses are proposed, their study would result in the rejection of the invalid ones. If the study of a competing hypothesis is prevented because of the faith in an unverified one, scientific progress is stalled. This has happened in the study of low dose radiation. Though radiation hormesis was hypothesized to reduce cancers in 1980, it could not be studied in humans because of the faith in the unverified linear no-threshold model hypothesis, likely resulting in over 15 million preventable cancer deaths worldwide during the past two decades, since evidence has accumulated supporting the validity of the phenomenon of radiation hormesis. Since our society has been guided by scientific advisory committees that ostensibly follow the scientific method, the long duration of such large casualties is indicative of systemic deficiencies in the infrastructure that has evolved in our society for the application of science. Some of these deficiencies have been identified in a few elements of the scientific infrastructure, and remedial steps suggested. Identifying and correcting such deficiencies may prevent similar tolls in the future. PMID:24910580

Testing Scientific Software: A Systematic Literature Review

PubMed Central

Kanewala, Upulee; Bieman, James M.

2014-01-01

Context Scientific software plays an important role in critical decision making, for example making weather predictions based on climate models, and computation of evidence for research publications. Recently, scientists have had to retract publications due to errors caused by software faults. Systematic testing can identify such faults in code. Objective This study aims to identify specific challenges, proposed solutions, and unsolved problems faced when testing scientific software. Method We conducted a systematic literature survey to identify and analyze relevant literature. We identified 62 studies that provided relevant information about testing scientific software. Results We found that challenges faced when testing scientific software fall into two main categories: (1) testing challenges that occur due to characteristics of scientific software such as oracle problems and (2) testing challenges that occur due to cultural differences between scientists and the software engineering community such as viewing the code and the model that it implements as inseparable entities. In addition, we identified methods to potentially overcome these challenges and their limitations. Finally we describe unsolved challenges and how software engineering researchers and practitioners can help to overcome them. Conclusions Scientific software presents special challenges for testing. Specifically, cultural differences between scientist developers and software engineers, along with the characteristics of the scientific software make testing more difficult. Existing techniques such as code clone detection can help to improve the testing process. Software engineers should consider special challenges posed by scientific software such as oracle problems when developing testing techniques. PMID:25125798

Cloud computing is one example of this e-Science trend. Our own work in the area of software reuse offers methods that can be used to improve new technological development, including cloud computing capabilities, to support scientific research practices. In this paper, we focus on software reuse and its potential to contribute to the development and evaluation of information systems and related services designed to support new capabilities for conducting scientific research.

Otto von Guericke and 17th century cosmology

NASA Astrophysics Data System (ADS)

Knobloch, Eberhard

Otto von Guericke's scientific method was based on reason and experimental science. His cosmology was embedded in theology and can be interpreted as a refutation of Descartes' worldview. He used Nicolaus Cusanus' theory of quantities in order to characterize space. The notion of space has to be distinguished from that of world or heaven. Forces play a crucial role in this respect described by Athanasius Kircher in his "Celestial Journey". Guericke read this work very diligently. In spite of some obvious similarities between Guericke's and Newton's scientific aims and methods there are crucial differences between the scientific convictions and results of these scholars.

Is there a need for a code of ethics in science communication and Communicating Uncertainties on Climate Change?

NASA Astrophysics Data System (ADS)

Cegnar, T.; Benestad, R.; Billard, C.

2010-09-01

The EMS Media team recognises that: Scientific knowledge is valuable for society, but it also becomes fragile in a media-dominated society where the distortion of facts clouds the validity of the information. The use of scientific titles in communication normally brings expectations of high standards regarding the information content. Freedom of speech is fragile in the sense that it can be diluted by a high proportion of false information. The value of scientific and scholastic titles is degraded when they are used to give the impression of false validity. Science communication is powerful, and implies a certain responsibility and ethical standard. The scientific community operates with a more or less tacit ethics code in all areas touching the scientists' activities. Even though many scientific questions cannot be completely resolved, there is a set of established and unequivocal scientific practices, methods, and tests, on which our scientific knowledge rests. Scientists are assumed to master the scientific practices, methods, and tests. High standard in science-related communication and media exposure, openness, and honesty will increase the relevance of science, academies, and scientists in the society, in addition to benefiting the society itself. Science communication is important to maintain and enhance the general appreciation of science. The value of the role of science is likely to increase with a reduced distance between scientists and the society and a lower knowledge barrier. An awareness about the ethical aspects of science and science communication may aid scientists in making decisions about how and what to say. Scientists are often not trained in communication or ethics. A set of guide lines may lower the barrier for scientists concerned about tacit codes to come forward and talk to the media. Recommendations: The mass media should seek more insight into scientific knowledge, history, principles, and societies. Journalists and artists should be encouraged and receive support to attend the large scientific conferences organised by e.g the EMS, EGU, AMS, and the AGU. National meteorological societies can contribute by promoting the idea of media participation, e.g. through statements and letters of opinion to news papers, in TV and radio. They can point to media awards and best-practice examples (such as the Norwegian collaboration between the national broadcasting corporation and the meteorological service yr.no.) Tacit ethics codes and expectations from scientists should be spelled out. The role of scientists should be clear, and national academies and member organisations are encouraged to provide a clear list of expectations. Statements drawing on the authority of science should have a basis in well-established and unequivocal scientific practices, methods, and tests. This means, for instance, that analysis and statistics must conform to well-established robust methods, avoiding 'cherry picking' and the misrepresentation of data. The information should also - to the greatest possible degree - be based on open source and transparent methods and data.

Synchronous international scientific mobility in the space of affiliations: evidence from Russia.

PubMed

Markova, Yulia V; Shmatko, Natalia A; Katchanov, Yurij L

2016-01-01

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.

Bayesian Methods and Universal Darwinism

NASA Astrophysics Data System (ADS)

Campbell, John

2009-12-01

Bayesian methods since the time of Laplace have been understood by their practitioners as closely aligned to the scientific method. Indeed a recent Champion of Bayesian methods, E. T. Jaynes, titled his textbook on the subject Probability Theory: the Logic of Science. Many philosophers of science including Karl Popper and Donald Campbell have interpreted the evolution of Science as a Darwinian process consisting of a `copy with selective retention' algorithm abstracted from Darwin's theory of Natural Selection. Arguments are presented for an isomorphism between Bayesian Methods and Darwinian processes. Universal Darwinism, as the term has been developed by Richard Dawkins, Daniel Dennett and Susan Blackmore, is the collection of scientific theories which explain the creation and evolution of their subject matter as due to the Operation of Darwinian processes. These subject matters span the fields of atomic physics, chemistry, biology and the social sciences. The principle of Maximum Entropy states that Systems will evolve to states of highest entropy subject to the constraints of scientific law. This principle may be inverted to provide illumination as to the nature of scientific law. Our best cosmological theories suggest the universe contained much less complexity during the period shortly after the Big Bang than it does at present. The scientific subject matter of atomic physics, chemistry, biology and the social sciences has been created since that time. An explanation is proposed for the existence of this subject matter as due to the evolution of constraints in the form of adaptations imposed on Maximum Entropy. It is argued these adaptations were discovered and instantiated through the Operations of a succession of Darwinian processes.

Scientific Ethics in Chemical Education

NASA Astrophysics Data System (ADS)

Kovac, Jeffrey

1996-10-01

Scientific ethics is a subset of professional ethics, the special rules of conduct adhered to by people engaged in those pursuits called professions. It is distinct from, but consistent with, both ordinary morality and moral theory. The codes of professional ethics derive from the two bargains that define a profession: the internal code of practice and the external bargain between the profession and society. While the informal code of professional conduct is well understood by working scientists, it is rarely explicitly included in the chemistry curriculum. Instead, we have relied on informal methods to teach students scientific ethics, a strategy that is haphazard at best. In this paper I argue that scientific ethics can and must be taught as part of the chemistry curriculum and that this is the best done through the case-study method. Many decisions made by working scientists have both a technical and an ethical component. Students need to learn how to make good decisions in professional ethics. The alternative is, at best, sloppy science and, at worst, scientific misconduct.

What Does Galileo's Discovery of Jupiter's Moons Tell Us About the Process of Scientific Discovery?

NASA Astrophysics Data System (ADS)

Lawson, Anton E.

In 1610, Galileo Galilei discovered Jupiter''smoons with the aid of a new morepowerful telescope of his invention. Analysisof his report reveals that his discoveryinvolved the use of at least three cycles ofhypothetico-deductive reasoning. Galileofirst used hypothetico-deductive reasoning to generateand reject a fixed star hypothesis.He then generated and rejected an ad hocastronomers-made-a-mistake hypothesis.Finally, he generated, tested, and accepted a moonhypothesis. Galileo''s reasoningis modeled in terms of Piaget''s equilibration theory,Grossberg''s theory of neurologicalactivity, a neural network model proposed by Levine &Prueitt, and another proposedby Kosslyn & Koenig. Given that hypothetico-deductivereasoning has played a rolein other important scientific discoveries, thequestion is asked whether it plays a rolein all important scientific discoveries. In otherwords, is hypothetico-deductive reasoningthe essence of the scientific method? Possiblealternative scientific methods, such asBaconian induction and combinatorial analysis,are explored and rejected as viablealternatives. Educational implications of thishypothetico-deductive view of scienceare discussed.

Automatic sentence extraction for the detection of scientific paper relations

NASA Astrophysics Data System (ADS)

Sibaroni, Y.; Prasetiyowati, S. S.; Miftachudin, M.

2018-03-01

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

Science information in the media: an academic approach to improve its intrinsic quality.

2002-01-01

The lay audience expresses a clear demand for scientific information, particularly when health and welfare are involved. For most people science is what they learn from the media. The need for good scientific journalism is pressing, to bridge the gap between the slow pace of science and the fast-moving and concise nature of successful mass communication. This academic postgraduate course was established by the Department of Pharmacological Sciences to train mediators to improve the quality of lay scientific dissemination. The programme focuses on teaching a method of selecting, analysing, understanding, mediating and diffusing scientific information to lay people. The course explores the theoretical and practical aspects of methods, techniques and channels of scientific communication. Case studies, practical exercises, and stages complement the theoretical curriculum. The teaching focus is on reducing the asymmetry between scientists and the public. The different backgrounds of students and the spread of topics are major challenges. Copyright 2002 Academic Press.

Ecological Equivalence Assessment Methods: What Trade-Offs between Operationality, Scientific Basis and Comprehensiveness?

PubMed

Bezombes, Lucie; Gaucherand, Stéphanie; Kerbiriou, Christian; Reinert, Marie-Eve; Spiegelberger, Thomas

2017-08-01

In many countries, biodiversity compensation is required to counterbalance negative impacts of development projects on biodiversity by carrying out ecological measures, called offset when the goal is to reach "no net loss" of biodiversity. One main issue is to ensure that offset gains are equivalent to impact-related losses. Ecological equivalence is assessed with ecological equivalence assessment methods taking into account a range of key considerations that we summarized as ecological, spatial, temporal, and uncertainty. When equivalence assessment methods take into account all considerations, we call them "comprehensive". Equivalence assessment methods should also aim to be science-based and operational, which is challenging. Many equivalence assessment methods have been developed worldwide but none is fully satisfying. In the present study, we examine 13 equivalence assessment methods in order to identify (i) their general structure and (ii) the synergies and trade-offs between equivalence assessment methods characteristics related to operationality, scientific-basis and comprehensiveness (called "challenges" in his paper). We evaluate each equivalence assessment methods on the basis of 12 criteria describing the level of achievement of each challenge. We observe that all equivalence assessment methods share a general structure, with possible improvements in the choice of target biodiversity, the indicators used, the integration of landscape context and the multipliers reflecting time lags and uncertainties. We show that no equivalence assessment methods combines all challenges perfectly. There are trade-offs between and within the challenges: operationality tends to be favored while scientific basis are integrated heterogeneously in equivalence assessment methods development. One way of improving the challenges combination would be the use of offset dedicated data-bases providing scientific feedbacks on previous offset measures.

Evaluation of medical research performance – position paper of the Association of the Scientific Medical Societies in Germany (AWMF)

Herrmann-Lingen, Christoph; Brunner, Edgar; Hildenbrand, Sibylle; Loew, Thomas H.; Raupach, Tobias; Spies, Claudia; Treede, Rolf-Detlef; Vahl, Christian-Friedrich; Wenz, Hans-Jürgen

Objective: The evaluation of medical research performance is a key prerequisite for the systematic advancement of medical faculties, research foci, academic departments, and individual scientists’ careers. However, it is often based on vaguely defined aims and questionable methods and can thereby lead to unwanted regulatory effects. The current paper aims at defining the position of German academic medicine toward the aims, methods, and consequences of its evaluation. Methods: During the Berlin Forum of the Association of the Scientific Medical Societies in Germany (AWMF) held on 18 October 2013, international experts presented data on methods for evaluating medical research performance. Subsequent discussions among representatives of relevant scientific organizations and within three ad-hoc writing groups led to a first draft of this article. Further discussions within the AWMF Committee for Evaluation of Performance in Research and Teaching and the AWMF Executive Board resulted in the final consented version presented here. Results: The AWMF recommends modifications to the current system of evaluating medical research performance. Evaluations should follow clearly defined and communicated aims and consist of both summative and formative components. Informed peer reviews are valuable but feasible in longer time intervals only. They can be complemented by objective indicators. However, the Journal Impact Factor is not an appropriate measure for evaluating individual publications or their authors. The scientific “impact” rather requires multidimensional evaluation. Indicators of potential relevance in this context may include, e.g., normalized citation rates of scientific publications, other forms of reception by the scientific community and the public, and activities in scientific organizations, research synthesis and science communication. In addition, differentiated recommendations are made for evaluating the acquisition of third-party funds and the promotion of junior scientists. Conclusions: With the explicit recommendations presented in the current position paper, the AWMF suggests enhancements to the practice of evaluating medical research performance by faculties, ministries and research funding organizations.

Scientists' conceptions of scientific inquiry: Revealing a private side of science

NASA Astrophysics Data System (ADS)

Reiff, Rebecca R.

Science educators, philosophers, and pre-service teachers have contributed to conceptualizing inquiry but missing from the inquiry forum is an in-depth research study concerning science faculty conceptions of scientific inquiry. The science education literature has tended to focus on certain aspects of doing, teaching, and understanding scientific inquiry without linking these concepts. As a result, conceptions of scientific inquiry have been disjointed and are seemingly unrelated. Furthermore, confusion surrounding the meaning of inquiry has been identified as a reason teachers are not using inquiry in instruction (Welch et al., 1981). Part of the confusion surrounding scientific inquiry is it has been defined differently depending on the context (Colburn, 2000; Lederman, 1998; Shymansky & Yore, 1980; Wilson & Koran, 1976). This lack of a common conception of scientific inquiry is the reason for the timely nature of this research. The result of scientific journeys is not to arrive at a stopping point or the final destination, but to refuel with questions to drive the pursuit of knowledge. A three-member research team conducted Interviews with science faculty members using a semi-structured interview protocol designed to probe the subject's conceptions of scientific inquiry. The participants represented a total of 52 science faculty members from nine science departments (anthropology, biology, chemistry, geology, geography, school of health, physical education and recreation (HPER), medical sciences, physics, and school of environmental science) at a large mid-western research university. The method of analysis used by the team was grounded theory (Strauss & Corbin, 1990; Glaser & Strauss, 1967), in which case the frequency of concepts, patterns, and themes were coded to categorize scientists' conceptions of scientific inquiry. The results from this study address the following components: understanding and doing scientific inquiry, attributes of scientists engaged in inquiry investigations, the relationship of scientific inquiry to the nature of science, whether the process of scientific inquiry follows the traditional scientific method, and the similarities and differences in conceptualizations of scientific inquiry across science disciplines. These findings represent a private side of science, which can be useful in characterizing key features of scientific inquiry to be incorporated into K--16 teaching practices.

The aim of this study is to develop lesson plans and student worksheets based socio-scientific issues on pollution environmental topic for seventh-grade junior high school students. Environmental pollution topic split into several subtopics namely air pollution, water pollution and soil pollution. The composing of lesson plans were developed based on socio-scientific issues with five stages, namely (1) Motivate; (2) Challenge; (3) Collect scientific evidence; (4) Analyse the evidence; (5) Build knowledge and make connections; and (6) Use evidence. While student worksheets contain articles on socio-scientific issues, practice, and there are a few questions to determine students’ reasoning. The method that is used in this research is research and development (R & D method). Development model used in this study is a model of Plomp that consists of four stages, namely: (1) Initial Research; (2) Design; (3) Realization or Construction; (4) Testing, evaluation and revision; (5) Implementation, while the research was limited to the fourth stage. Lesson plans and student worksheets based on socio-scientific issues was validated through an expert validation. The result showed that lesson plans and student worksheets based socio-scientific issues on pollution theme have a very decent and be able to apply in science classroom.

Evaluation of university scientific research ability based on the output of sci-tech papers: A D-AHP approach

PubMed Central

Wang, Lifang

2017-01-01

University scientific research ability is an important indicator to express the strength of universities. In this paper, the evaluation of university scientific research ability is investigated based on the output of sci-tech papers. Four university alliances from North America, UK, Australia, and China, are selected as the case study of the university scientific research evaluation. Data coming from Thomson Reuters InCites are collected to support the evaluation. The work has contributed new framework to the issue of university scientific research ability evaluation. At first, we have established a hierarchical structure to show the factors that impact the evaluation of university scientific research ability. Then, a new MCDM method called D-AHP model is used to implement the evaluation and ranking of different university alliances, in which a data-driven approach is proposed to automatically generate the D numbers preference relations. Next, a sensitivity analysis has been given to show the impact of weights of factors and sub-factors on the evaluation result. At last, the results obtained by using different methods are compared and discussed to verify the effectiveness and reasonability of this study, and some suggestions are given to promote China’s scientific research ability.

Fetz, Marcelo

2017-01-01

Natural history in the eighteenth and nineteenth centuries has been widely debated in the field of the social sciences. This paper explores the social negotiation of boundaries in the Encyclopédie and romantic science. Highlighting the importance of imagination and aesthetics to the scientific realms, we perceive a different comprehension of the scientific field through the empirical study of how scientific demarcation is constructed. Works by Erasmus Darwin, Goethe, and Humboldt illustrate how reliable science was performed through atypical scientific methods. After pointing out the links between literary, artistic, and scientific works, we then debate a series of changes that framed the scientific imagery of romantic and encyclopaedic sciences.

[Physical therapy for idiopathic scoliosis].

Steffan, K

2015-11-01

The objective is the description and summary of the current state of idiopathic scoliosis treatment with physical therapy based on new scientific knowledge and concluded from more than 15 years of experience as a leading physician in two well-known clinics specializing in the conservative treatment of scoliosis. Based on current scientific publications on physical therapy in scoliosis treatment and resulting from the considerable personal experience gained working with conservative treatment and consulting scoliosis patients (as inpatients and outpatients), the current methods of physical therapy have been compared and evaluated. Physical therapy according to Schroth and Vojta therapy are at present the most common and effective methods in the physical treatment of idiopathic scoliosis. These methods can be applied during inpatient or outpatient treatment or intensified in the practice of specialized therapists. As there are only a few scientific studies on this subject, the author's findings are based mainly on his own experiences of the conservative treatment of idiopathic scoliosis. Athough these experiences are the results of over 15 years of working in the field of therapy, and the Schroth method in combination with corrective bracing presents highly promising results, it would nevertheless be desirable to conduct detailed scientific studies to verify the effectiveness of conservative treatment.

Training innovative talents, as one of the major aims for Chinese universities, needs to reform the traditional teaching methods. The research-oriented teaching method has been introduced and its connotation and significance for Chinese university teaching have been discussed for years. However, few practical teaching methods for routine class teaching were proposed. In this paper, a comprehensive and concrete research-oriented teaching model with contents of reference value and evaluation method for class teaching was proposed based on the current teacher-guiding teaching model in China. We proposed that the research-oriented teaching model should include at least seven aspects on: (1) telling the scientific history for the skills to find out scientific questions; (2) replaying the experiments for the skills to solve scientific problems; (3) analyzing experimental data for learning how to draw a conclusion; (4) designing virtual experiments for learning how to construct a proposal; (5) teaching the lesson as the detectives solve the crime for learning the logic in scientific exploration; (6) guiding students how to read and consult the relative references; (7) teaching students differently according to their aptitude and learning ability. In addition, we also discussed how to evaluate the effects of the research-oriented teaching model in examination.

The approach presumes a close connection between the classical scientific method: observing, hypothesis forming, hypothesis testing, and generalizing from the results of the testing, and the writing process: inventing and prewriting, drafting, and revising. The project has four goals: 1. To introduce students to the relations between scientific method, academic inquiry, and the writing process; 2. To help students see that academic inquiry, the work of generating, testing, and validating knowledge and then applying that knowledge in real contexts, is actually a hybrid form of the scientific method; 3. To encourage students to connect the work they are doing in the writing classroom with the work they are doing in other classes so they can transfer the skills learned in one context to the other; and 4. To cause students who have previously been alienated by science and science teaching to reconsider their attitudes, and to see the powerful influence of science and scientific thinking in our world. In short, we are teaching science literacy in a humanities classroom. The materials we use include science-based reading and the kinds of writing typically required in science classes. The poster presents the basic premises of the project, samples of class materials, and preliminary results of a controlled pre- and post-test of student attitudes toward science and writing, analyzed especially according to gender and minority status. We also present insights by participating instructors including a female graduate teaching assistant who had been trained as a scientist and a male who had not.

Anthropogenic ``Global Warming'' Alarmism: Illuminating some Scientific and Methodological Flaws

NASA Astrophysics Data System (ADS)

Gould, Larry

2009-10-01

There continues to be an increasing number of scientists and public figures around the world who are challenging the dominant political- and mediadriven claims that have been bolstered by so-called ``consensus'' scientific views -- that dangerous ``global warming/climate change'' is caused primarily by human-produced carbon dioxide. This general talk will show that the weight of scientific evidence strongly contradicts the alarmist claims. It will also explain what are some of the methodological flaws that continue to threaten the scientific method.

Science and culture around the Montessori's first "Children's Houses" in Rome (1907-1915).

PubMed

Foschi, Renato

2008-01-01

Between 1907 and 1908, Maria Montessori's (1870-1952) educational method was elaborated at the Children's Houses of the San Lorenzo district in Rome. This pioneering experience was the basis for the international fame that came to Montessori after the publication of her 1909 volume dedicated to her "Method." The "Montessori Method" was considered by some to be scientific, liberal, and revolutionary. The present article focuses upon the complex contexts of the method's elaboration. It shows how the Children's Houses developed in relation to a particular scientific and cultural eclecticism. It describes the factors that both favored and hindered the method's elaboration, by paying attention to the complex network of social, institutional, and scientific relationships revolving around the figure of Maria Montessori. A number of "contradictory" dimensions of Montessori's experience are also examined with a view to helping to revise her myth and offering the image of a scholar who was a real early-twentieth-century prototype of a "multiple" behavioral scientist.

Popova, Olga; Popov, Boris; Romanov, Dmitry; Evseeva, Marina

Optimel: software for selecting the optimal method automates the process of selecting a solution method from the optimization methods domain. Optimel features practical novelty. It saves time and money when conducting exploratory studies if its objective is to select the most appropriate method for solving an optimization problem. Optimel features theoretical novelty because for obtaining the domain a new method of knowledge structuring was used. In the Optimel domain, extended quantity of methods and their properties are used, which allows identifying the level of scientific studies, enhancing the user's expertise level, expand the prospects the user faces and opening up new research objectives. Optimel can be used both in scientific research institutes and in educational institutions.

'Introspectionism' and the mythical origins of scientific psychology.

PubMed

Costall, Alan

2006-12-01

According to the majority of the textbooks, the history of modern, scientific psychology can be tidily encapsulated in the following three stages. Scientific psychology began with a commitment to the study of mind, but based on the method of introspection. Watson rejected introspectionism as both unreliable and effete, and redefined psychology, instead, as the science of behaviour. The cognitive revolution, in turn, replaced the mind as the subject of study, and rejected both behaviourism and a reliance on introspection. This paper argues that all three stages of this history are largely mythical. Introspectionism was never a dominant movement within modern psychology, and the method of introspection never went away. Furthermore, this version of psychology's history obscures some deep conceptual problems, not least surrounding the modern conception of "behaviour," that continues to make the scientific study of consciousness seem so weird.

Widening the adoption of workflows to include human and human-machine scientific processes

Salayandia, L.; Pinheiro da Silva, P.; Gates, A. Q.

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

Whole earth modeling: developing and disseminating scientific software for computational geophysics.

NASA Astrophysics Data System (ADS)

Kellogg, L. H.

2016-12-01

Historically, a great deal of specialized scientific software for modeling and data analysis has been developed by individual researchers or small groups of scientists working on their own specific research problems. As the magnitude of available data and computer power has increased, so has the complexity of scientific problems addressed by computational methods, creating both a need to sustain existing scientific software, and expand its development to take advantage of new algorithms, new software approaches, and new computational hardware. To that end, communities like the Computational Infrastructure for Geodynamics (CIG) have been established to support the use of best practices in scientific computing for solid earth geophysics research and teaching. Working as a scientific community enables computational geophysicists to take advantage of technological developments, improve the accuracy and performance of software, build on prior software development, and collaborate more readily. The CIG community, and others, have adopted an open-source development model, in which code is developed and disseminated by the community in an open fashion, using version control and software repositories like Git. One emerging issue is how to adequately identify and credit the intellectual contributions involved in creating open source scientific software. The traditional method of disseminating scientific ideas, peer reviewed publication, was not designed for review or crediting scientific software, although emerging publication strategies such software journals are attempting to address the need. We are piloting an integrated approach in which authors are identified and credited as scientific software is developed and run. Successful software citation requires integration with the scholarly publication and indexing mechanisms as well, to assign credit, ensure discoverability, and provide provenance for software.

``In the United States today science, as science, is under attack as never before (Defend Science, defendscience.org).'' Beyond, and underlying, the many particular attacks and outrages in different spheres and policy areas is the question of the scientific method and whether it is going to be upheld and applied, or whether -- even in the realm of science itself -- that method is going to be replaced by something antagonistically opposed to the scientific method. These attacks are increasingly coming from powerful forces, in and out of the Bush administration, with an extreme right-wing political agenda, a Biblical-literalist ideological agenda, and theocratic aspirations for society. Individual scientists may be atheists, agnostics, or may hold various religious beliefs, but if religious and theistic elements are forced into the definition of science, then the scientific process is undermined and science cannot really be practiced. We can and must develop a society wide battle, initiated by scientists, but involving ever growing masses of people to defend science and scientific thinking. Scientists from various fields must be mobilized to issue a public call to millions with this urgent message as the beginning of this effort. I will discuss the necessity, possibility, and some initial efforts toward developing this kind of societal movement in defense of science.

Writing has dramatically evolved in the world; however, qualification of scientific production in Colombia has not, including the improper use of decree 1444/93 and 1279/02. The last of these decrees authorized Colciencias, the Colombian government institute created to support scientific research in Colombia, to establish rules for its implementation. Colciencias decided to evaluate scientific papers produced in Colombia based on the non-scientific method of the "impact factor", and considered that citations in MEDLINE/PubMed and PsylNFO were second line publications thus violating Colombian law. This affects not only the progress of scientific research in Colombia but also researchers' income and puts Colombia's scientific journals and publications at great disadvantage. Scientific papers indexed in qualified databases such as MEDLINE/PubMed must be judged according to law in order to prevent further injuries to the developing Colombian scientific production.

A model of "integrated scientific method" and its application for the analysis of instruction

NASA Astrophysics Data System (ADS)

Rusbult, Craig Francis

A model of 'integrated scientific method' (ISM) was constructed as a framework for describing the process of science in terms of activities (formulating a research problem, and inventing and evaluating actions--such as selecting and inventing theories, evaluating theories, designing experiments, and doing experiments--intended to solve the problem) and evaluation criteria (empirical, conceptual, and cultural-personal). Instead of trying to define the scientific method, ISM is intended to serve as a flexible framework that--by varying the characteristics of its components, their integrated relationships, and their relative importance can be used to describe a variety of scientific methods, and a variety of perspectives about what constitutes an accurate portrayal of scientific methods. This framework is outlined visually and verbally, followed by an elaboration of the framework and my own views about science, and an evaluation of whether ISM can serve as a relatively neutral framework for describing a wide range of science practices and science interpretations. ISM was used to analyze an innovative, guided inquiry classroom (taught by Susan Johnson, using Genetics Construction Kit software) in which students do simulated scientific research by solving classical genetics problems that require effect-to-cause reasoning and theory revision. The immediate goal of analysis was to examine the 'science experiences' of students, to determine how the 'structure of instruction' provides opportunities for these experiences. Another goal was to test and improve the descriptive and analytical utility of ISM. In developing ISM, a major objective was to make ISM educationally useful. A concluding discussion includes controversies about "the nature of science" and how to teach it, how instruction can expand opportunities for student experience, and how goal-oriented intentional learning (using ISM might improve the learning, retention, and transfer of thinking skills. Potential educational applications of ISM could involve its use for instructional analysis or design, or for teaching students in the classroom; or ISM and IDM (a closely related, generalized 'integrated design method') could play valuable roles in a 'wide spiral' curriculum designed for the coordinated teaching of thinking skills, including creativity and critical thinking, across a wide range of subjects.

Leveraging Transcultural Enrollments to Enhance Application of the Scientific Method

NASA Astrophysics Data System (ADS)

Loudin, M.

2013-12-01

Continued growth of transcultural academic programs presents an opportunity for all of the students involved to improve utilization of the scientific method. Our own business success depends on how effectively we apply the scientific method, and so it is unsurprising that our hiring programs focus on three broad areas of capability among applicants which are strongly related to the scientific method. These are 1) ability to continually learn up-to-date earth science concepts, 2) ability to effectively and succinctly communicate in the English language, both oral and written, and 3) ability to employ behaviors that are advantageous with respect to the various phases of the scientific method. This third area is often the most difficult to develop, because neither so-called Western nor Eastern cultures encourage a suite of behaviors that are ideally suited. Generally, the acceptance of candidates into academic programs, together with subsequent high performance evidenced by grades, is a highly valid measure of continuous learning capability. Certainly, students for whom English is not a native language face additional challenges, but succinct and effective communication is an art which requires practice and development, regardless of native language. The ability to communicate in English is crucial, since it is today's lingua franca for both science and commerce globally. Therefore, we strongly support the use of frequent English written assignments and oral presentations as an integral part of all scientific academic programs. There is no question but that this poses additional work for faculty; nevertheless it is a key ingredient to the optimal development of students. No one culture has a monopoly with respect to behaviors that promote effective leveraging of the scientific method. For instance, the growing complexity of experimental protocols argues for a high degree of interdependent effort, which is more often associated with so-called Eastern than Western cultures. Conversely, the willingness to express new ideas regardless of one's status is a key to formation of new or disruptive hypotheses, and is more typically seen in Western than Eastern cultures. The opportunity posed by transcultural academic programs lies in: 1) participants learning which of their own preferred behaviors either promote or hinder excellence in scientific results, 2) observing and learning from others' behaviors, and 3) in learning to apply their individual strengths as part of a team. The term 'inclusion' provides a useful shorthand for how academic departments might approach the development of 'ideal' scientific behaviors in their students. An inclusive approach recognizes that a 'one size fits all' approach is not likely to succeed; different individuals have different preferred behaviors, which are not fully predicted by their home culture. It also implies the use of more group projects than many departments currently employ, in order to provide realistic learning laboratories for the students. An emphasis on behaviors can be an uncomfortable idea in 'hard science' circles, both in academia and in industry. However, as scientists we have a responsibility to develop our successors to deliver the best possible scientific results, and the growth of transcultural academic programs presents us an opportunity that we should not miss.

Exploration on the reform of the science and engineering experiment teaching based on the combination with teaching and scientific research

Song, Peng

2017-08-01

The existing problems of the experiment education in colleges and universities are analyzed. Take the science and engineering specialty as example, the idea of the combination with teaching and scientific research is discussed. The key problems are how the scientific research and scientific research achievements are used effectively in the experiment education, how to effectively use scientific research laboratories and scientific researchers. Then, a specialty experiment education system is established which is good for the teaching in accordance of all students' aptitude. The research in this paper can give the construction of the experiment teaching methods and the experiment system reform for the science and engineering specialties in colleges and universities.

This paper is to make further research on facilitating the large-scale scientific computing on the grid and the desktop grid platform. The related issues include the programming method, the overhead of the high-level program interface based middleware, and the data anticipate migration. The block based Gauss Jordan algorithm as a real example of large-scale scientific computing is used to evaluate those issues presented above. The results show that the high-level based program interface makes the complex scientific applications on large-scale scientific platform easier, though a little overhead is unavoidable. Also, the data anticipation migration mechanism can improve the efficiency of the platform which needs to process big data based scientific applications. PMID:24574931

Quantifying the Ease of Scientific Discovery

2012-01-01

It has long been known that scientific output proceeds on an exponential increase, or more properly, a logistic growth curve. The interplay between effort and discovery is clear, and the nature of the functional form has been thought to be due to many changes in the scientific process over time. Here I show a quantitative method for examining the ease of scientific progress, another necessary component in understanding scientific discovery. Using examples from three different scientific disciplines – mammalian species, chemical elements, and minor planets – I find the ease of discovery to conform to an exponential decay. In addition, I show how the pace of scientific discovery can be best understood as the outcome of both scientific output and ease of discovery. A quantitative study of the ease of scientific discovery in the aggregate, such as done here, has the potential to provide a great deal of insight into both the nature of future discoveries and the technical processes behind discoveries in science.

Life sciences faculty agree that developing scientific literacy is an integral part of undergraduate education and report that they teach these skills. However, few measures of scientific literacy are available to assess students' proficiency in using scientific literacy skills to solve scenarios in and beyond the undergraduate biology classroom. In this paper, we describe the development, validation, and testing of the Test of Scientific Literacy Skills (TOSLS) in five general education biology classes at three undergraduate institutions. The test measures skills related to major aspects of scientific literacy: recognizing and analyzing the use of methods of inquiry that lead to scientific knowledge and the ability to organize, analyze, and interpret quantitative data and scientific information. Measures of validity included correspondence between items and scientific literacy goals of the National Research Council and Project 2061, findings from a survey of biology faculty, expert biology educator reviews, student interviews, and statistical analyses. Classroom testing contexts varied both in terms of student demographics and pedagogical approaches. We propose that biology instructors can use the TOSLS to evaluate their students' proficiencies in using scientific literacy skills and to document the impacts of curricular reform on students' scientific literacy.

Barz, Daniela Luminita; Achimaş-Cadariu, Andrei

2016-01-01

Scientific reasoning has been studied from a variety of theoretical perspectives, which have tried to identify the underlying mechanisms responsible for the development of this particular cognitive process. Scientific reasoning has been defined as a problem-solving process that involves critical thinking in relation to content, procedural, and epistemic knowledge. The development of scientific reasoning in medical education was influenced by current paradigmatic trends, it could be traced along educational curriculum and followed cognitive processes. The purpose of the present review is to discuss the role of scientific reasoning in medical education and outline educational methods for its development. Current evidence suggests that medical education should foster a new ways of development of scientific reasoning, which include exploration of the complexity of scientific inquiry, and also take into consideration the heterogeneity of clinical cases found in practice.

Reading, Writing, and Presenting Original Scientific Research: A Nine-Week Course in Scientific Communication for High School Students†

2015-01-01

High school students are not often given opportunities to communicate scientific findings to their peers, the general public, and/or people in the scientific community, and therefore they do not develop scientific communication skills. We present a nine-week course that can be used to teach high school students, who may have no previous experience, how to read and write primary scientific articles and how to discuss scientific findings with a broad audience. Various forms of this course have been taught for the past 10 years as part of an intensive summer research program for rising high school seniors that is coordinated by the Young Scientist Program at Washington University in St. Louis. The format presented here includes assessments for efficacy through both rubric-based methods and student self-assessment surveys. PMID:26753027

[Hans Gross and the beginning of criminology on a scientific basis].

PubMed

Bachhiesl, Christian

2007-01-01

Modern criminology--if one wants to consider it a separate scientific discipline at all--is usually perceived as being mainly influenced by the methods of natural sciences supplemented by components from the field of psychology, which, at least in some of its conceptions, tends to define itself as a natural science, too. If we take a look at the history of science, we will see development of criminology in this direction was not necessarily inevitable. The scientific work of the Austrian Hans Gross (1847-1915), one of the founding fathers of scientific criminology, serves as an example of the way how natural sciences and their exact methods became established in the methodological apparatus of modern criminology, although in praxi his claim for the application of exact methods was all too often replaced by irrational and intuitive ways of working. Still, Hans Gross' fundamental decision for the exact methods derived from the natural sciences is an important step towards a criminology that can be understood as a part of natural sciences, largely superseding the methods of cultural sciences and anthropological philosophy. This approach made the (criminal) human being an object of measurement and can result in the concept of man as a mere phenomenon of quantity. This is, on the one hand, ethically questionable; on the other hand, it made modern criminology more efficient and successful.

Scientific Misconduct in India: Causes and Perpetuation.

Along with economic strength, space technology and software expertise, India is also a leading nation in fraudulent scientific research. The problem is worsened by vested interests working in concert for their own benefits. These self-promoting cartels, together with biased evaluation methods and weak penal systems, combine to perpetuate scientific misconduct. Some of these issues are discussed in this commentary, with supporting examples and possible solutions.

[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.

The Cornell Kitchen: Housing and Design Research in Postwar America.

PubMed

Penner, Barbara

2018-01-01

The Cornell Kitchen (1950-55) was produced at Cornell University by a multidisciplinary team with expertise in home economics, engineering, architecture, and psychology. It promised to deliver rational design, functional principles, aesthetic appeal, and emotional satisfaction in one prefabricated, easy-to-install package. This article sets out the kitchen's history from its design to its field-testing phase to its impact on postwar kitchens. It argues that the kitchen represents an important effort to approach housing in a more scientific way; scientific methods were deployed to understand both the physical and socio-psychological problems of dwelling. The project also sought to introduce a specific model for leveraging housing research into the real world, partnering with industry to mass produce scientific designs. Social scientific methods were hence used to create not only more livable but also more saleable products in an effort to appeal to manufacturers and consumers alike.

The latest edition of the Oxford Dictionary (1989) defines archaeology as '... the scientific study of the remains and monuments of the prehistoric period'. It is not surprising, therefore, that modern archaeology draws as much as possible on scientific methods of investigation developed in other fields. In the last ten years the powerful method of quantitative isotope analysis has brought a new dimension to the examination of archaeological finds.

1997-06-01

Providing large numbers of general education students with an introduction to science is a challenge. To meet this challenge, a quarter-long neurophysiology project was developed for use in an introductory biology course. The primary goals of this multistep project were to introduce students to the scientific method, scientific writing, on-line scientific bibliographic databases, and the scientific literature, while improving their academic literacy skills. Students began by collecting data on their own circadian rhythms in autonomic, motor, and cognitive function, reliably demonstrating the predicted circadian changes in heart rate, eye-hand coordination, and adding speed. Students wrote a journal-style article using pooled class data. Students were prepared to write the paper by several methods that were designed to improve academic language skills, including a library training exercise, "modeling" of the writing assignment, and drafting of subsections of the paper. This multistep neurophysiology project represents a significant commitment of time by both students and instructors, but produces a valuable finished product and ideally gives introductory students a positive first experience with science.

This paper describes a computing environment which supports computer-based scientific research work. Key features include support for automatic distributed scheduling and execution and computer-based scientific experimentation. A new flexible and extensible scheduling technique that is responsive to a user`s scheduling constraints, such as the ordering of program results and the specification of task assignments and processor utilization levels, is presented. An easy-to-use constraint language for specifying scheduling constraints, based on the relational database query language SQL, is described along with a search-based algorithm for fulfilling these constraints. A set of performance studies show that the environment can schedule and executemore » program graphs on a network of workstations as the user requests. A method for automatically generating computer-based scientific experiments is described. Experiments provide a concise method of specifying a large collection of parameterized program executions.

Four stages of a scientific discipline; four types of scientist.

PubMed

Shneider, Alexander M

2009-05-01

In this article I propose the classification of the evolutionary stages that a scientific discipline evolves through and the type of scientists that are the most productive at each stage. I believe that each scientific discipline evolves sequentially through four stages. Scientists at stage one introduce new objects and phenomena as subject matter for a new scientific discipline. To do this they have to introduce a new language adequately describing the subject matter. At stage two, scientists develop a toolbox of methods and techniques for the new discipline. Owing to this advancement in methodology, the spectrum of objects and phenomena that fall into the realm of the new science are further understood at this stage. Most of the specific knowledge is generated at the third stage, at which the highest number of original research publications is generated. The majority of third-stage investigation is based on the initial application of new research methods to objects and/or phenomena. The purpose of the fourth stage is to maintain and pass on scientific knowledge generated during the first three stages. Groundbreaking new discoveries are not made at this stage. However, new ways to present scientific information are generated, and crucial revisions are often made of the role of the discipline within the constantly evolving scientific environment. The very nature of each stage determines the optimal psychological type and modus operandi of the scientist operating within it. Thus, it is not only the talent and devotion of scientists that determines whether they are capable of contributing substantially but, rather, whether they have the 'right type' of talent for the chosen scientific discipline at that time. Understanding the four different evolutionary stages of a scientific discipline might be instrumental for many scientists in optimizing their career path, in addition to being useful in assembling scientific teams, precluding conflicts and maximizing productivity. The proposed model of scientific evolution might also be instrumental for society in organizing and managing the scientific process. No public policy aimed at stimulating the scientific process can be equally beneficial for all four stages. Attempts to apply the same criteria to scientists working on scientific disciplines at different stages of their scientific evolution would be stimulating for one and detrimental for another. In addition, researchers operating at a certain stage of scientific evolution might not possess the mindset adequate to evaluate and stimulate a discipline that is at a different evolutionary stage. This could be the reason for suboptimal implementation of otherwise well-conceived scientific policies.

Visualization techniques to aid in the analysis of multi-spectral astrophysical data sets

NASA Technical Reports Server (NTRS)

Brugel, Edward W.; Domik, Gitta O.; Ayres, Thomas R.

1993-01-01

The goal of this project was to support the scientific analysis of multi-spectral astrophysical data by means of scientific visualization. Scientific visualization offers its greatest value if it is not used as a method separate or alternative to other data analysis methods but rather in addition to these methods. Together with quantitative analysis of data, such as offered by statistical analysis, image or signal processing, visualization attempts to explore all information inherent in astrophysical data in the most effective way. Data visualization is one aspect of data analysis. Our taxonomy as developed in Section 2 includes identification and access to existing information, preprocessing and quantitative analysis of data, visual representation and the user interface as major components to the software environment of astrophysical data analysis. In pursuing our goal to provide methods and tools for scientific visualization of multi-spectral astrophysical data, we therefore looked at scientific data analysis as one whole process, adding visualization tools to an already existing environment and integrating the various components that define a scientific data analysis environment. As long as the software development process of each component is separate from all other components, users of data analysis software are constantly interrupted in their scientific work in order to convert from one data format to another, or to move from one storage medium to another, or to switch from one user interface to another. We also took an in-depth look at scientific visualization and its underlying concepts, current visualization systems, their contributions, and their shortcomings. The role of data visualization is to stimulate mental processes different from quantitative data analysis, such as the perception of spatial relationships or the discovery of patterns or anomalies while browsing through large data sets. Visualization often leads to an intuitive understanding of the meaning of data values and their relationships by sacrificing accuracy in interpreting the data values. In order to be accurate in the interpretation, data values need to be measured, computed on, and compared to theoretical or empirical models (quantitative analysis). If visualization software hampers quantitative analysis (which happens with some commercial visualization products), its use is greatly diminished for astrophysical data analysis. The software system STAR (Scientific Toolkit for Astrophysical Research) was developed as a prototype during the course of the project to better understand the pragmatic concerns raised in the project. STAR led to a better understanding on the importance of collaboration between astrophysicists and computer scientists.

Science Camps for Introducing Nature of Scientific Inquiry Through Student Inquiries in Nature: Two Applications with Retention Study

NASA Astrophysics Data System (ADS)

Leblebicioglu, G.; Abik, N. M.; Capkinoglu, E.; Metin, D.; Dogan, E. Eroglu; Cetin, P. S.; Schwartz, R.

2017-08-01

Scientific inquiry is widely accepted as a method of science teaching. Understanding its characteristics, called Nature of Scientific Inquiry (NOSI), is also necessary for a whole conception of scientific inquiry. In this study NOSI aspects were taught explicitly through student inquiries in nature in two summer science camps. Students conducted four inquiries through their questions about surrounding soil, water, plants, and animals under the guidance of university science educators. At the end of each investigation, students presented their inquiry. NOSI aspects were made explicit by one of the science educators in the context of the investigations. Effectiveness of the science camp program and its retention were determined by applying Views of Scientific Inquiry (VOSI-S) (Schwartz et al. 2008) questionnaire as pre-, post-, and retention test after two months. The patterns in the data were similar. The science camp program was effective in developing three of six NOSI aspects which were questions guide scientific research, multiple methods of research, and difference between data and evidence. Students' learning of these aspects was retained. Discussion about these and the other three aspects is included in the paper. Implications of differences between school and out-of-school science experiences are also discussed.

A comparison of bilingual education and generalist teachers' approaches to scientific biliteracy

NASA Astrophysics Data System (ADS)

Garza, Esther

The purpose of this study was to determine if educators were capitalizing on bilingual learners' use of their biliterate abilities to acquire scientific meaning and discourse that would formulate a scientific biliterate identity. Mixed methods were used to explore teachers' use of biliteracy and Funds of Knowledge (Moll, L., Amanti, C., Neff, D., & Gonzalez, N., 1992; Gonzales, Moll, & Amanti, 2005) from the students' Latino heritage while conducting science inquiry. The research study explored four constructs that conceptualized scientific biliteracy. The four constructs include science literacy, science biliteracy, reading comprehension strategies and students' cultural backgrounds. There were 156 4th-5th grade bilingual and general education teachers in South Texas that were surveyed using the Teacher Scientific Biliteracy Inventory (TSBI) and five teachers' science lessons were observed. Qualitative findings revealed that a variety of scientific biliteracy instructional strategies were frequently used in both bilingual and general education classrooms. The language used to deliver this instruction varied. A General Linear Model revealed that classroom assignment, bilingual or general education, had a significant effect on a teacher's instructional approach to employ scientific biliteracy. A simple linear regression found that the TSBI accounted for 17% of the variance on 4th grade reading benchmarks. Mixed methods results indicated that teachers were utilizing scientific biliteracy strategies in English, Spanish and/or both languages. Household items and science experimentation at home were encouraged by teachers to incorporate the students' cultural backgrounds. Finally, science inquiry was conducted through a universal approach to science learning versus a multicultural approach to science learning.

Is it all in the game? Flow experience and scientific practices during an INPLACE mobile game

NASA Astrophysics Data System (ADS)

Bressler, Denise M.

Mobile science learning games show promise for promoting scientific practices and high engagement. Researchers have quantified this engagement according to flow theory. Using an embedded mixed methods design, this study investigated whether an INPLACE mobile game promotes flow experience, scientific practices, and effective team collaboration. Students playing the game (n=59) were compared with students in a business-as-usual control activity (n=120). Using an open-ended instrument designed to measure scientific practices and a self-report flow survey, this study empirically assessed flow and learner's scientific practices. The game players had significantly higher levels of flow and scientific practices. Using a multiple case study approach, collaboration among game teams (n=3 teams) were qualitatively compared with control teams (n=3 teams). Game teams revealed not only higher levels of scientific practices but also higher levels of engaged responses and communal language. Control teams revealed lower levels of scientific practice along with higher levels of rejecting responses and command language. Implications for these findings are discussed.

A case report illustrates how multidisciplinary translational teams can be assessed using outcome, process, and developmental types of evaluation using a mixed-methods approach. Types of evaluation appropriate for teams are considered in relation to relevant research questions and assessment methods. Logic models are applied to scientific projects and team development to inform choices between methods within a mixed-methods design. Use of an expert panel is reviewed, culminating in consensus ratings of 11 multidisciplinary teams and a final evaluation within a team-type taxonomy. Based on team maturation and scientific progress, teams were designated as (a) early in development, (b) traditional, (c) process focused, or (d) exemplary. Lessons learned from data reduction, use of mixed methods, and use of expert panels are explored.

The communication of science to the public: A philosophy of television

NASA Astrophysics Data System (ADS)

Carter, Nicholas Brent

The communication of science to the public via the mass media, in particular the televisual format, requires a modified approach to the traditional presumptive models of communicative style. Conventional models of science communication are based on implicit but unexamined assumptions that the most effective and important means of transmission of scientific information are efforts aimed at the attentive segments of the population through specialized and detailed formats. Attempts to reach inattentive audiences with scientific information are customarily unsuccessful or have been deemed unnecessary altogether. The proposed model submits that not only are endeavors to communicate scientific ideas to the disinterested populace of overriding importance but can be quite successful if production styles are altered to reflect more "interest-motivating" designs. A new thrust toward capturing the attention of disinterested audiences before attempting to directly disseminate scientific ideas is proposed. By examining the constraints of both the scientific and communication systems, the model demonstrates that current methods utilized to transmit scientific information are incompatible with the notion of reaching more inattentive audiences. The assumptions of scientific communicators and the community of scientists are critiqued through analysis of the diverse body of research devoted to the public transmission of science and scientific concepts. The foundations of televisual communication are explored and a model of commercial television programming is proffered to redirect classical scientific production methods to more visually interesting, narrative-driven styles. A call to shift focus of scientific communication from the products of science to the process of science is also suggested in part to achieve such a direction. The model proposes that the most important aspect of this process is to begin to show scientists as human beings and the conceptual accessibility of both the scientists and their endeavors. For this to occur, scientists must begin to alter their behaviors and attitudes toward the public dissemination of their research and start by educating themselves on the communicative demands of the media. Communicators must also begin to change their long-held strategies of scientific communication by focusing on the interest factor of their stories before attempting to transmit complicated scientific information.

Revisiting the scientific method to improve rigor and reproducibility of immunohistochemistry in reproductive science.

PubMed

Manuel, Sharrón L; Johnson, Brian W; Frevert, Charles W; Duncan, Francesca E

2018-04-21

Immunohistochemistry (IHC) is a robust scientific tool whereby cellular components are visualized within a tissue, and this method has been and continues to be a mainstay for many reproductive biologists. IHC is highly informative if performed and interpreted correctly, but studies have shown that the general use and reporting of appropriate controls in IHC experiments is low. This omission of the scientific method can result in data that lacks rigor and reproducibility. In this editorial, we highlight key concepts in IHC controls and describe an opportunity for our field to partner with the Histochemical Society to adopt their IHC guidelines broadly as researchers, authors, ad hoc reviewers, editorial board members, and editors-in-chief. Such cross-professional society interactions will ensure that we produce the highest quality data as new technologies emerge that still rely upon the foundations of classic histological and immunohistochemical principles.

Importance of scientific resources among local public health practitioners.

Fields, Robert P; Stamatakis, Katherine A; Duggan, Kathleen; Brownson, Ross C

2015-04-01

We examined the perceived importance of scientific resources for decision-making among local health department (LHD) practitioners in the United States. We used data from LHD practitioners (n = 849). Respondents ranked important decision-making resources, methods for learning about public health research, and academic journal use. We calculated descriptive statistics and used logistic regression to measure associations of individual and LHD characteristics with importance of scientific resources. Systematic reviews of scientific literature (24.7%) were most frequently ranked as important among scientific resources, followed by scientific reports (15.9%), general literature review articles (6.5%), and 1 or a few scientific studies (4.8%). Graduate-level education (adjusted odds ratios [AORs] = 1.7-3.5), larger LHD size (AORs = 2.0-3.5), and leadership support (AOR = 1.6; 95% confidence interval = 1.1, 2.3) were associated with a higher ranking of importance of scientific resources. Graduate training, larger LHD size, and leadership that supports a culture of evidence-based decision-making may increase the likelihood of practitioners viewing scientific resources as important. Targeting communication channels that practitioners view as important can also guide research dissemination strategies.

Unsupervised learning on scientific ocean drilling datasets from the South China Sea

Tse, Kevin C.; Chiu, Hon-Chim; Tsang, Man-Yin; Li, Yiliang; Lam, Edmund Y.

2018-06-01

Unsupervised learning methods were applied to explore data patterns in multivariate geophysical datasets collected from ocean floor sediment core samples coming from scientific ocean drilling in the South China Sea. Compared to studies on similar datasets, but using supervised learning methods which are designed to make predictions based on sample training data, unsupervised learning methods require no a priori information and focus only on the input data. In this study, popular unsupervised learning methods including K-means, self-organizing maps, hierarchical clustering and random forest were coupled with different distance metrics to form exploratory data clusters. The resulting data clusters were externally validated with lithologic units and geologic time scales assigned to the datasets by conventional methods. Compact and connected data clusters displayed varying degrees of correspondence with existing classification by lithologic units and geologic time scales. K-means and self-organizing maps were observed to perform better with lithologic units while random forest corresponded best with geologic time scales. This study sets a pioneering example of how unsupervised machine learning methods can be used as an automatic processing tool for the increasingly high volume of scientific ocean drilling data.

The assessment of science: the relative merits of post-publication review, the impact factor, and the number of citations.

PubMed

Eyre-Walker, Adam; Stoletzki, Nina

2013-10-01

The assessment of scientific publications is an integral part of the scientific process. Here we investigate three methods of assessing the merit of a scientific paper: subjective post-publication peer review, the number of citations gained by a paper, and the impact factor of the journal in which the article was published. We investigate these methods using two datasets in which subjective post-publication assessments of scientific publications have been made by experts. We find that there are moderate, but statistically significant, correlations between assessor scores, when two assessors have rated the same paper, and between assessor score and the number of citations a paper accrues. However, we show that assessor score depends strongly on the journal in which the paper is published, and that assessors tend to over-rate papers published in journals with high impact factors. If we control for this bias, we find that the correlation between assessor scores and between assessor score and the number of citations is weak, suggesting that scientists have little ability to judge either the intrinsic merit of a paper or its likely impact. We also show that the number of citations a paper receives is an extremely error-prone measure of scientific merit. Finally, we argue that the impact factor is likely to be a poor measure of merit, since it depends on subjective assessment. We conclude that the three measures of scientific merit considered here are poor; in particular subjective assessments are an error-prone, biased, and expensive method by which to assess merit. We argue that the impact factor may be the most satisfactory of the methods we have considered, since it is a form of pre-publication review.

2013-01-01

The assessment of scientific publications is an integral part of the scientific process. Here we investigate three methods of assessing the merit of a scientific paper: subjective post-publication peer review, the number of citations gained by a paper, and the impact factor of the journal in which the article was published. We investigate these methods using two datasets in which subjective post-publication assessments of scientific publications have been made by experts. We find that there are moderate, but statistically significant, correlations between assessor scores, when two assessors have rated the same paper, and between assessor score and the number of citations a paper accrues. However, we show that assessor score depends strongly on the journal in which the paper is published, and that assessors tend to over-rate papers published in journals with high impact factors. If we control for this bias, we find that the correlation between assessor scores and between assessor score and the number of citations is weak, suggesting that scientists have little ability to judge either the intrinsic merit of a paper or its likely impact. We also show that the number of citations a paper receives is an extremely error-prone measure of scientific merit. Finally, we argue that the impact factor is likely to be a poor measure of merit, since it depends on subjective assessment. We conclude that the three measures of scientific merit considered here are poor; in particular subjective assessments are an error-prone, biased, and expensive method by which to assess merit. We argue that the impact factor may be the most satisfactory of the methods we have considered, since it is a form of pre-publication review. However, we emphasise that it is likely to be a very error-prone measure of merit that is qualitative, not quantitative. PMID:24115908

The objectives of this quantitative survey research were (1) to establish the level of scientific reasoning (SR) skills among science, mathematics and engineering (SME) undergraduates in Malaysian Institute of Higher Learning (IHL); (b) to identify the types of instructional methods in teaching SME at universities; and (c) to map instructional methods employed to the level of SR skills among the undergraduates. There were six universities according to zone involved in this study using the stratification random sampling technique. For each university, the faculties that involved were faculties which have degree students in science, mathematics and engineering programme. A total of 975 students were participated in this study. There were two instruments used in this study namely, the Lawson Scientific Reasoning Skills Test and the Lecturers' Teaching Style Survey. The descriptive statistics and the inferential statistics such as mean, t-test and Pearson correlation were used to analyze the data. Findings of the study showed that most students had concrete level of scientific reasoning skills where the overall mean was 3.23. The expert and delegator were dominant lecturers' teaching styles according to students' perception. In addition, there was no correlation between lecturers' teaching style and the level of scientific reasoning skills. Thus, this study cannot map the dominant lecturers' teaching style to the level of scientific reasoning skills of Science, Mathematics and Engineering undergraduates in Malaysian Public Institute of Higher Learning. Nevertheless, this study gave some indications that the expert and delegator teaching styles were not contributed to the development of students' scientific reasoning skills. This study can be used as a baseline for Science, Mathematics and Engineering undergraduates' level of scientific reasoning skills in Malaysian Public Institute of Higher Learning. Overall, this study also opens an endless source of other researchers to investigate more areas on scientific reasoning skills so that the potential instructional model can be developed to enhance students' level of scientific reasoning skills in Malaysian Public Institute of Higher Learning.

The rapidly evolving discipline of biological and biomedical engineering requires adaptive instructional approaches that teach students to target and solve multi-pronged and ill-structured problems at the cutting edge of scientific research. Here we present a modular approach to designing a lab-based course in the emerging field of biofabrication and biological design, leading to a final capstone design project that requires students to formulate and test a hypothesis using the scientific method. Students were assessed on a range of metrics designed to evaluate the format of the course, the efficacy of the format for teaching new topics and concepts, and the depth of the contribution this course made to students training for biological engineering careers. The evaluation showed that the problem-based format of the course was well suited to teaching students how to use the scientific method to investigate and uncover the fundamental biological design rules that govern the field of biofabrication. We show that this approach is an efficient and effective method of translating emergent scientific principles from the lab bench to the classroom and training the next generation of biological and biomedical engineers for careers as researchers and industry practicians.

The Contingency of Laws of Nature in Science and Theology

NASA Astrophysics Data System (ADS)

Jaeger, Lydia

2010-10-01

The belief that laws of nature are contingent played an important role in the emergence of the empirical method of modern physics. During the scientific revolution, this belief was based on the idea of voluntary creation. Taking up Peter Mittelstaedt’s work on laws of nature, this article explores several alternative answers which do not overtly make use of metaphysics: some laws are laws of mathematics; macroscopic laws can emerge from the interplay of numerous subsystems without any specific microscopic nomic structures (John Wheeler’s “law without law”); laws are the preconditions of scientific experience (Kant); laws are theoretical abstractions which only apply in very limited circumstances (Nancy Cartwright). Whereas Cartwright’s approach is in tension with modern scientific methodology, the first three strategies count as illuminating, though partial answers. It is important for the empirical method of modern physics that these three strategies, even when taken together, do not provide a complete explanation of the order of nature. Thus the question of why laws are valid is still relevant. In the concluding section, I argue that the traditional answer, based on voluntary creation, provides the right balance of contingency and coherence which is in harmony with modern scientific method.

Limitations on scientific prediction and how they could affect repository licensing

Van Konynenburg, R.A.

The best possibility for gaining an understanding of the likely future behavior of a high level nuclear waste disposal system is to use the scientific method. However, the scientific approach has inherent limitations when it comes to making long-term predictions with confidence. This paper examines some of these limiting factors as well as the criteria for admissibility of scientific evidence in the legal arena, and concludes that the prospects are doubtful for successful licensing of a potential repository under the regulations that are now being reconsidered. Suggestions am made for remedying this situation.

Data Friction Meets Social Friction: Challenges for standardization in emerging fields of geoscience

NASA Astrophysics Data System (ADS)

Darch, P. T.

2017-12-01

Many interdisciplinary endeavors in the geosciences occur in emergent scientific fields. These fields are often characterized by heterogeneity of methods for production and collection of data, and by data scarcity. This paper presents findings about processes of methods standardization from a long-term case study of an emergent, data-scarce field, the deep subseafloor biosphere. Researchers come from many physical and life science backgrounds to study interactions between microbial life in the seafloor and the physical environment they inhabit. Standardization of methods for collecting data promises multiple benefits to this field, including: Addressing data scarcity through enabling greater data reuse and promoting better interoperability with large scale infrastructures; Fostering stronger collaborative links between researchers distributed across institutions and backgrounds. Ongoing standardization efforts in the field do not only involve scientific judgments about which among a range of methods is most efficient, least biased, or most reliable. Instead, these efforts also encounter multiple difficult social challenges, including: Lack of agreed upon criteria about how to judge competing methods: should efficiency, bias, or reliability take priority?; Lack of resources to carry out the work necessary to determine standards, particularly acute in emergent fields; Concerns that standardization is premature in such a new field, foreclosing the possibility of better methods being developed in the future; Concerns that standardization could prematurely shut down important scientific debates; Concerns among some researchers that their own work may become obsolete should the methods chosen as standard be different from their own. The success of these standardization efforts will depend on addressing both scientific and social dimensions, to ensure widespread acceptance among researchers in the field.

The evaluation of medical research performance is a key prerequisite for the systematic advancement of medical faculties, research foci, academic departments, and individual scientists' careers. However, it is often based on vaguely defined aims and questionable methods and can thereby lead to unwanted regulatory effects. The current paper aims at defining the position of German academic medicine toward the aims, methods, and consequences of its evaluation. During the Berlin Forum of the Association of the Scientific Medical Societies in Germany (AWMF) held on 18 October 2013, international experts presented data on methods for evaluating medical research performance. Subsequent discussions among representatives of relevant scientific organizations and within three ad-hoc writing groups led to a first draft of this article. Further discussions within the AWMF Committee for Evaluation of Performance in Research and Teaching and the AWMF Executive Board resulted in the final consented version presented here. The AWMF recommends modifications to the current system of evaluating medical research performance. Evaluations should follow clearly defined and communicated aims and consist of both summative and formative components. Informed peer reviews are valuable but feasible in longer time intervals only. They can be complemented by objective indicators. However, the Journal Impact Factor is not an appropriate measure for evaluating individual publications or their authors. The scientific "impact" rather requires multidimensional evaluation. Indicators of potential relevance in this context may include, e.g., normalized citation rates of scientific publications, other forms of reception by the scientific community and the public, and activities in scientific organizations, research synthesis and science communication. In addition, differentiated recommendations are made for evaluating the acquisition of third-party funds and the promotion of junior scientists. With the explicit recommendations presented in the current position paper, the AWMF suggests enhancements to the practice of evaluating medical research performance by faculties, ministries and research funding organizations.

An assessment of the risk of foreign animal disease introduction into the United States of America through garbage from Alaskan cruise ships.

1993-12-01

The United States Department of Agriculture, Animal and Plant Health Inspection Service (USDA-APHIS) has been exploring methods of quantitative risk assessment to support decision-making, provide risk management options and identify research needs. With current changes in world trade, regulatory decisions must have a scientific basis which is transparent, consistent, documentable and defensible. These quantitative risk assessment methods are described in an accompanying paper in this issue. In the present article, the authors provide an illustration by presenting an application of these methods. Prior to proposing changes in regulations, USDA officials requested an assessment of the risk of introduction of foreign animal disease to the United States of America through garbage from Alaskan cruise ships. The risk assessment team used a combination of quantitative and qualitative methods to evaluate this question. Quantitative risk assessment methods were used to estimate the amount of materials of foreign origin being sent to Alaskan landfills. This application of quantitative risk assessment illustrates the flexibility of the methods in addressing specific questions. By applying these methods, specific areas were identified where more scientific information and research were needed. Even with limited information, the risk assessment provided APHIS management with a scientific basis for a regulatory decision.

Sherlock Holmes: scientific detective.

PubMed

Snyder, Laura J

2004-09-01

Sherlock Holmes was intended by his creator, Arthur Conan Doyle, to be a 'scientific detective'. Conan Doyle criticized his predecessor Edgar Allan Poe for giving his creation - Inspector Dupin - only the 'illusion' of scientific method. Conan Doyle believed that he had succeeded where Poe had failed; thus, he has Watson remark that Holmes has 'brought detection as near an exact science as it will ever be brought into the world.' By examining Holmes' methods, it becomes clear that Conan Doyle modelled them on certain images of science that were popular in mid- to late-19th century Britain. Contrary to a common view, it is also evident that rather than being responsible for the invention of forensic science, the creation of Holmes was influenced by the early development of it.

Data mart construction based on semantic annotation of scientific articles: A case study for the prioritization of drug targets.

Semantic text annotation enables the association of semantic information (ontology concepts) to text expressions (terms), which are readable by software agents. In the scientific scenario, this is particularly useful because it reveals a lot of scientific discoveries that are hidden within academic articles. The Biomedical area has more than 300 ontologies, most of them composed of over 500 concepts. These ontologies can be used to annotate scientific papers and thus, facilitate data extraction. However, in the context of a scientific research, a simple keyword-based query using the interface of a digital scientific texts library can return more than a thousand hits. The analysis of such a large set of texts, annotated with such numerous and large ontologies, is not an easy task. Therefore, the main objective of this work is to provide a method that could facilitate this task. This work describes a method called Text and Ontology ETL (TOETL), to build an analytical view over such texts. First, a corpus of selected papers is semantically annotated using distinct ontologies. Then, the annotation data is extracted, organized and aggregated into the dimensional schema of a data mart. Besides the TOETL method, this work illustrates its application through the development of the TaP DM (Target Prioritization data mart). This data mart has focus on the research of gene essentiality, a key concept to be considered when searching for genes showing potential as anti-infective drug targets. This work reveals that the proposed approach is a relevant tool to support decision making in the prioritization of new drug targets, being more efficient than the keyword-based traditional tools.

2004-01-01

Background With the rapid expansion of scientific research, the ability to effectively find or integrate new domain knowledge in the sciences is proving increasingly difficult. Efforts to improve and speed up scientific discovery are being explored on a number of fronts. However, much of this work is based on traditional search and retrieval approaches and the bibliographic citation presentation format remains unchanged. Methods Case study. Results The Telemakus KnowledgeBase System provides flexible new tools for creating knowledgebases to facilitate retrieval and review of scientific research reports. In formalizing the representation of the research methods and results of scientific reports, Telemakus offers a potential strategy to enhance the scientific discovery process. While other research has demonstrated that aggregating and analyzing research findings across domains augments knowledge discovery, the Telemakus system is unique in combining document surrogates with interactive concept maps of linked relationships across groups of research reports. Conclusion Based on how scientists conduct research and read the literature, the Telemakus KnowledgeBase System brings together three innovations in analyzing, displaying and summarizing research reports across a domain: (1) research report schema, a document surrogate of extracted research methods and findings presented in a consistent and structured schema format which mimics the research process itself and provides a high-level surrogate to facilitate searching and rapid review of retrieved documents; (2) research findings, used to index the documents, allowing searchers to request, for example, research studies which have studied the relationship between neoplasms and vitamin E; and (3) visual exploration interface of linked relationships for interactive querying of research findings across the knowledgebase and graphical displays of what is known as well as, through gaps in the map, what is yet to be tested. The rationale and system architecture are described and plans for the future are discussed. PMID:15507158

Research Prototype: Automated Analysis of Scientific and Engineering Semantics

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

2001-01-01

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

The steadily increasing size of scientific Monte Carlo simulations and the desire for robust, correct, and reproducible results necessitates rigorous testing procedures for scientific simulations in order to detect numerical problems and programming bugs. However, the testing paradigms developed for deterministic algorithms have proven to be ill suited for stochastic algorithms. In this paper we demonstrate explicitly how the technique of statistical hypothesis testing, which is in wide use in other fields of science, can be used to devise automatic and reliable tests for Monte Carlo methods, and we show that these tests are able to detect some of the common problems encountered in stochastic scientific simulations. We argue that hypothesis testing should become part of the standard testing toolkit for scientific simulations.

The rise of information science: a changing landscape for soil science

Roudier, Pierre; Ritchie, Alistair; Hedley, Carolyn; Medyckyj-Scott, David

2015-07-01

The last 15 years have seen the rapid development of a wide range of information technologies. Those developments have been impacting all fields of science, at every step of the scientific method: data collection, data analysis, inference, science communication and outreach. The rate at which data is being generated is increasing exponentially, giving opportunities to improve our understanding of soils. Parallel developments in computing hardware and methods, such as machine learning, open ways to not only harness the '”data deluge”, but also offer a new way to generate knowledge. Finally, emerging data and information delivery protocols are leveraging the outreach power of the World Wide Web to disseminate scientific data and information, and increase their use and understanding outside the boundaries of a given scientific field. However, the nature of this data is mostly new to soil science, and requires adaptation to its diversity and volume. In particular, the integration of the significant amount of legacy soil data collected throughout decades of soil science can be problematic when all necessary metadata is not available. Likewise, knowledge accumulated by our scientific field needs to be acknowledged by - rather than opposed to - numerical methods. While the introduction of this set of emerging technologies is enabling soil science from different points of view, its successful implementation depends on the ability of soil scientists to act as knowledge brokers and support numerical methods.

Scientific Process Flowchart Assessment (SPFA): A Method for Evaluating Changes in Understanding and Visualization of the Scientific Process in a Multidisciplinary Student Population.

PubMed

Wilson, Kristy J; Rigakos, Bessie

The scientific process is nonlinear, unpredictable, and ongoing. Assessing the nature of science is difficult with methods that rely on Likert-scale or multiple-choice questions. This study evaluated conceptions about the scientific process using student-created visual representations that we term "flowcharts." The methodology, Scientific Process Flowchart Assessment (SPFA), consisted of a prompt and rubric that was designed to assess students' understanding of the scientific process. Forty flowcharts representing a multidisciplinary group without intervention and 26 flowcharts representing pre- and postinstruction were evaluated over five dimensions: connections, experimental design, reasons for doing science, nature of science, and interconnectivity. Pre to post flowcharts showed a statistically significant improvement in the number of items and ratings for the dimensions. Comparison of the terms used and connections between terms on student flowcharts revealed an enhanced and more nuanced understanding of the scientific process, especially in the areas of application to society and communication within the scientific community. We propose that SPFA can be used in a variety of circumstances, including in the determination of what curricula or interventions would be useful in a course or program, in the assessment of curriculum, or in the evaluation of students performing research projects. © 2016 K.

Scientific dishonesty—a nationwide survey of doctoral students in Norway

PubMed Central

2013-01-01

Background The knowledge of scientific dishonesty is scarce and heterogeneous. Therefore this study investigates the experiences with and the attitudes towards various forms of scientific dishonesty among PhD-students at the medical faculties of all Norwegian universities. Method Anonymous questionnaire distributed to all post graduate students attending introductory PhD-courses at all medical faculties in Norway in 2010/2011. Descriptive statistics. Results 189 of 262 questionnaires were returned (72.1%). 65% of the respondents had not, during the last year, heard or read about researchers who committed scientific dishonesty. One respondent had experienced pressure to fabricate and to falsify data, and one had experienced pressure to plagiarize data. On average 60% of the respondents were uncertain whether their department had a written policy concerning scientific conduct. About 11% of the respondents had experienced unethical pressure concerning the order of authors during the last 12 months. 10% did not find it inappropriate to report experimental data without having conducted the experiment and 38% did not find it inappropriate to try a variety of different methods of analysis to find a statistically significant result. 13% agreed that it is acceptable to selectively omit contradictory results to expedite publication and 10% found it acceptable to falsify or fabricate data to expedite publication, if they were confident of their findings. 79% agreed that they would be willing to report misconduct to a responsible official. Conclusion Although there is less scientific dishonesty reported in Norway than in other countries, dishonesty is not unknown to doctoral students. Some forms of scientific misconduct are considered to be acceptable by a significant minority. There was little awareness of relevant policies for scientific conduct, but a high level of willingness to report misconduct. PMID:23289954

Modern scientific evidence pertaining to criminal investigations in the Chosun dynasty era (1392-1897 A.C.E.) in Korea.

PubMed

Nam, Yun Sik; Won, Sung-Ok; Lee, Kang-Bong

2014-07-01

A guidebook detailing the process of forensic investigation was written in 1440 A.C.E. It outlines the fundamentals and details of each element of criminal investigation during the era of the Chosun dynasty in Korea. Because this old guidebook was written in terms of personal experience rather than on scientific basis, it includes many fallacies from the perspective of modern forensic science. However, the book describes methods to form a scientific basis for the experiments performed. We demonstrate the modern scientific basis for ancient methods to monitor trace amounts of blood and detect lethal arsenic poisoning from a postmortem examination as described in this old forensic guidebook. Traces of blood and arsenic poisoning were detected according to the respective color changes of brownish red, due to the reaction of ferric ions in blood with acetic ions of vinegar, and dark blue, due to the reaction of silver with arsenic sulfide. © 2014 American Academy of Forensic Sciences.

On Modeling Research Work for Describing and Filtering Scientific Information

NASA Astrophysics Data System (ADS)

Sicilia, Miguel-Ángel

Existing models for Research Information Systems (RIS) properly address the description of people and organizations, projects, facilities and their outcomes, e.g. papers, reports or patents. While this is adequate for the recording and accountability of research investments, helping researchers in finding relevant people, organizations or results requires considering both the content of research work and also its context. The content is not only related to the domain area, but it requires modeling methodological issues as variables, instruments or scientific methods that can then be used as search criteria. The context of research work is determined by the ongoing projects or scientific interests of an individual or a group, and can be expressed using the same methodological concepts. However, modeling methodological issues is notably complex and dependent on the scientific discipline and research area. This paper sketches the main requirements for those models, providing some motivating examples that could serve as a point of departure for future attempts in developing an upper ontology for research methods and tools.

Assessing and Evaluating Multidisciplinary Translational Teams: A Mixed Methods Approach

PubMed Central

Wooten, Kevin C.; Rose, Robert M.; Ostir, Glenn V.; Calhoun, William J.; Ameredes, Bill T.; Brasier, Allan R.

2014-01-01

A case report illustrates how multidisciplinary translational teams can be assessed using outcome, process, and developmental types of evaluation using a mixed methods approach. Types of evaluation appropriate for teams are considered in relation to relevant research questions and assessment methods. Logic models are applied to scientific projects and team development to inform choices between methods within a mixed methods design. Use of an expert panel is reviewed, culminating in consensus ratings of 11 multidisciplinary teams and a final evaluation within a team type taxonomy. Based on team maturation and scientific progress, teams were designated as: a) early in development, b) traditional, c) process focused, or d) exemplary. Lessons learned from data reduction, use of mixed methods, and use of expert panels are explored. PMID:24064432

Preparing Scientists to be Community Partners

NASA Astrophysics Data System (ADS)

Pandya, R. E.

2012-12-01

Many students, especially students from historically under-represented communities, leave science majors or avoid choosing them because scientific careers do not offer enough opportunity to contribute to their communities. Citizen science, or public participation in scientific research, may address these challenges. At its most collaborative, it means inviting communities to partner in every step of the scientific process from defining the research question to applying the results to community priorities. In addition to attracting and retaining students, this level of community engagement will help diversify science, ensure the use and usability of our science, help buttress public support of science, and encourage the application of scientific results to policy. It also offers opportunities to tackle scientific questions that can't be accomplished in other way and it is demonstrably effective at helping people learn scientific concepts and methods. In order to learn how to prepare scientists for this kind of intensive community collaboration, we examined several case studies, including a project on disease and public health in Africa and the professionally evaluated experience of two summer interns in Southern Louisiana. In these and other cases, we learned that scientific expertise in a discipline has to be accompanied by a reservoir of humility and respect for other ways of knowing, the ability to work collaboratively with a broad range of disciplines and people, patience and enough career stability to allow that patience, and a willingness to adapt research to a broader set of scientific and non-scientific priorities. To help students achieve this, we found that direct instruction in participatory methods, mentoring by community members and scientists with participatory experience, in-depth training on scientific ethics and communication, explicit articulation of the goal of working with communities, and ample opportunity for personal reflection were essential. There is much more to learn about preparing students for these collaborative approaches, and the principal goal of sharing these strategies is to spark a conversation about the ways we prepare scientists and the public to work together in an increasingly collaborative scientific enterprise.

Eliciting Taiwanese high school students' scientific ontological and epistemic beliefs

Lin, Tzung-Jin; Tsai, Chin-Chung

2017-11-01

This study employed the interview method to clarify the underlying dimensions of and relationships between students' scientific ontological and epistemic beliefs. Forty Taiwanese high school students were invited to participate in this study. Through content analysis of the participants' interview responses two ontological dimensions including 'status of nature' and 'structure of nature' were identified and found to be associated with each other. The two epistemic dimensions 'knowledge' and 'knowing' aligned with past literature were also categorised. Besides five pattern variations in terms of the aforementioned four dimensions were recognised based on the students' philosophical stances on their scientific ontological and epistemic beliefs. According to the Chi-square test results both dimensions of scientific ontological beliefs were significantly related to the two dimensions of scientific epistemic beliefs respectively. In general the students who endorsed a more sophisticated ontological stance regarding the status and structure of nature tended to express a more mature epistemic stance toward scientific knowledge and ways of knowing. The results suggest that the maturation of students' scientific epistemic beliefs may serve as a precursor and the fundamental step in promoting the sophistication of students' scientific ontological beliefs.

Semantic Information Processing of Physical Simulation Based on Scientific Concept Vocabulary Model

NASA Astrophysics Data System (ADS)

Kino, Chiaki; Suzuki, Yoshio; Takemiya, Hiroshi

Scientific Concept Vocabulary (SCV) has been developed to actualize Cognitive methodology based Data Analysis System: CDAS which supports researchers to analyze large scale data efficiently and comprehensively. SCV is an information model for processing semantic information for physics and engineering. In the model of SCV, all semantic information is related to substantial data and algorisms. Consequently, SCV enables a data analysis system to recognize the meaning of execution results output from a numerical simulation. This method has allowed a data analysis system to extract important information from a scientific view point. Previous research has shown that SCV is able to describe simple scientific indices and scientific perceptions. However, it is difficult to describe complex scientific perceptions by currently-proposed SCV. In this paper, a new data structure for SCV has been proposed in order to describe scientific perceptions in more detail. Additionally, the prototype of the new model has been constructed and applied to actual data of numerical simulation. The result means that the new SCV is able to describe more complex scientific perceptions.

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

The production of security documents provides a cache of interesting problems ranging across a broad spectrum. Some of the problems do not have rigorous scientific solutions available at this time and provide opportunities for less structured approaches such as AI. AI methods can be used in conjunction with traditional scientific and computational methods. The most productive applications of AI occur when this marriage of methods can be carried out without motivation to prove that one method is better than the other.

Visualization techniques to aid in the analysis of multispectral astrophysical data sets

NASA Technical Reports Server (NTRS)

Brugel, E. W.; Domik, Gitta O.; Ayres, T. R.

1993-01-01

The goal of this project was to support the scientific analysis of multi-spectral astrophysical data by means of scientific visualization. Scientific visualization offers its greatest value if it is not used as a method separate or alternative to other data analysis methods but rather in addition to these methods. Together with quantitative analysis of data, such as offered by statistical analysis, image or signal processing, visualization attempts to explore all information inherent in astrophysical data in the most effective way. Data visualization is one aspect of data analysis. Our taxonomy as developed in Section 2 includes identification and access to existing information, preprocessing and quantitative analysis of data, visual representation and the user interface as major components to the software environment of astrophysical data analysis. In pursuing our goal to provide methods and tools for scientific visualization of multi-spectral astrophysical data, we therefore looked at scientific data analysis as one whole process, adding visualization tools to an already existing environment and integrating the various components that define a scientific data analysis environment. As long as the software development process of each component is separate from all other components, users of data analysis software are constantly interrupted in their scientific work in order to convert from one data format to another, or to move from one storage medium to another, or to switch from one user interface to another. We also took an in-depth look at scientific visualization and its underlying concepts, current visualization systems, their contributions and their shortcomings. The role of data visualization is to stimulate mental processes different from quantitative data analysis, such as the perception of spatial relationships or the discovery of patterns or anomalies while browsing through large data sets. Visualization often leads to an intuitive understanding of the meaning of data values and their relationships by sacrificing accuracy in interpreting the data values. In order to be accurate in the interpretation, data values need to be measured, computed on, and compared to theoretical or empirical models (quantitative analysis). If visualization software hampers quantitative analysis (which happens with some commercial visualization products), its use is greatly diminished for astrophysical data analysis. The software system STAR (Scientific Toolkit for Astrophysical Research) was developed as a prototype during the course of the project to better understand the pragmatic concerns raised in the project. STAR led to a better understanding on the importance of collaboration between astrophysicists and computer scientists. Twenty-one examples of the use of visualization for astrophysical data are included with this report. Sixteen publications related to efforts performed during or initiated through work on this project are listed at the end of this report.

A survey of scientific literacy to provide a foundation for designing science communication in Japan.

Kawamoto, Shishin; Nakayama, Minoru; Saijo, Miki

2013-08-01

There are various definitions and survey methods for scientific literacy. Taking into consideration the contemporary significance of scientific literacy, we have defined it with an emphasis on its social aspects. To acquire the insights needed to design a form of science communication that will enhance the scientific literacy of each individual, we conducted a large-scale random survey within Japan of individuals older than 18 years, using a printed questionnaire. The data thus acquired were analyzed using factor analysis and cluster analysis to create a 3-factor/4-cluster model of people's interest and attitude toward science, technology and society and their resulting tendencies. Differences were found among the four clusters in terms of the three factors: scientific factor, social factor, and science-appreciating factor. We propose a plan for designing a form of science communication that is appropriate to this current status of scientific literacy in Japan.

Johnson, Branden B; Dieckmann, Nathan F

2017-10-01

A survey experiment assessed response to five explanations of scientific disputes: problem complexity, self-interest, values, competence, and process choices (e.g. theories and methods). A US lay sample ( n = 453) did not distinguish interests from values, nor competence from process, as explanations of disputes. Process/competence was rated most likely and interests/values least; all, on average, were deemed likely to explain scientific disputes. Latent class analysis revealed distinct subgroups varying in their explanation preferences, with a more complex latent class structure for participants who had heard of scientific disputes in the past. Scientific positivism and judgments of science's credibility were the strongest predictors of latent class membership, controlling for scientific reasoning, political ideology, confidence in choice, scenario, education, gender, age, and ethnicity. The lack of distinction observed overall between different explanations, as well as within classes, raises challenges for further research on explanations of scientific disputes people find credible and why.

A rule-based named-entity recognition method for knowledge extraction of evidence-based dietary recommendations

PubMed Central

2017-01-01

Evidence-based dietary information represented as unstructured text is a crucial information that needs to be accessed in order to help dietitians follow the new knowledge arrives daily with newly published scientific reports. Different named-entity recognition (NER) methods have been introduced previously to extract useful information from the biomedical literature. They are focused on, for example extracting gene mentions, proteins mentions, relationships between genes and proteins, chemical concepts and relationships between drugs and diseases. In this paper, we present a novel NER method, called drNER, for knowledge extraction of evidence-based dietary information. To the best of our knowledge this is the first attempt at extracting dietary concepts. DrNER is a rule-based NER that consists of two phases. The first one involves the detection and determination of the entities mention, and the second one involves the selection and extraction of the entities. We evaluate the method by using text corpora from heterogeneous sources, including text from several scientifically validated web sites and text from scientific publications. Evaluation of the method showed that drNER gives good results and can be used for knowledge extraction of evidence-based dietary recommendations. PMID:28644863

Applied Use Value of Scientific Information for Management of Ecosystem Services

Raunikar, R. P.; Forney, W.; Bernknopf, R.; Mishra, S.

2012-12-01

The U.S. Geological Survey has developed and applied methods for quantifying the value of scientific information (VOI) that are based on the applied use value of the information. In particular the applied use value of U.S. Geological Survey information often includes efficient management of ecosystem services. The economic nature of U.S. Geological Survey scientific information is largely equivalent to that of any information, but we focus application of our VOI quantification methods on the information products provided freely to the public by the U.S. Geological Survey. We describe VOI economics in general and illustrate by referring to previous studies that use the evolving applied use value methods, which includes examples of the siting of landfills in Louden County, the mineral exploration efficiencies of finer resolution geologic maps in Canada, and improved agricultural production and groundwater protection in Eastern Iowa possible with Landsat moderate resolution satellite imagery. Finally, we describe the adaptation of the applied use value method to the case of streamgage information used to improve the efficiency of water markets in New Mexico.

Progress in The Semantic Analysis of Scientific Code

NASA Technical Reports Server (NTRS)

Stewart, Mark

2000-01-01

This paper concerns a procedure that analyzes aspects of the meaning or semantics of scientific and engineering code. This procedure involves taking a user's existing code, adding semantic declarations for some primitive variables, and parsing this annotated code using multiple, independent expert parsers. These semantic parsers encode domain knowledge and recognize formulae in different disciplines including physics, numerical methods, mathematics, and geometry. The parsers will automatically recognize and document some static, semantic concepts and help locate some program semantic errors. These techniques may apply to a wider range of scientific codes. If so, the techniques could reduce the time, risk, and effort required to develop and modify scientific codes.

Learning Physics-based Models in Hydrology under the Framework of Generative Adversarial Networks

NASA Astrophysics Data System (ADS)

Karpatne, A.; Kumar, V.

2017-12-01

Generative adversarial networks (GANs), that have been highly successful in a number of applications involving large volumes of labeled and unlabeled data such as computer vision, offer huge potential for modeling the dynamics of physical processes that have been traditionally studied using simulations of physics-based models. While conventional physics-based models use labeled samples of input/output variables for model calibration (estimating the right parametric forms of relationships between variables) or data assimilation (identifying the most likely sequence of system states in dynamical systems), there is a greater opportunity to explore the full power of machine learning (ML) methods (e.g, GANs) for studying physical processes currently suffering from large knowledge gaps, e.g. ground-water flow. However, success in this endeavor requires a principled way of combining the strengths of ML methods with physics-based numerical models that are founded on a wealth of scientific knowledge. This is especially important in scientific domains like hydrology where the number of data samples is small (relative to Internet-scale applications such as image recognition where machine learning methods has found great success), and the physical relationships are complex (high-dimensional) and non-stationary. We will present a series of methods for guiding the learning of GANs using physics-based models, e.g., by using the outputs of physics-based models as input data to the generator-learner framework, and by using physics-based models as generators trained using validation data in the adversarial learning framework. These methods are being developed under the broad paradigm of theory-guided data science that we are developing to integrate scientific knowledge with data science methods for accelerating scientific discovery.

These semantic parsers encode domain knowledge and recognize formulae in different disciplines including physics, numerical methods, mathematics, and geometry. The parsers will automatically recognize and document some static, semantic concepts and help locate some program semantic errors. Results are shown for three intensively studied codes and seven blind test cases; all test cases are state of the art scientific codes. These techniques may apply to a wider range of scientific codes. If so, the techniques could reduce the time, risk, and effort required to develop and modify scientific codes.

Information extraction from full text scientific articles: where are the keywords?

PubMed

Shah, Parantu K; Perez-Iratxeta, Carolina; Bork, Peer; Andrade, Miguel A

2003-05-29

To date, many of the methods for information extraction of biological information from scientific articles are restricted to the abstract of the article. However, full text articles in electronic version, which offer larger sources of data, are currently available. Several questions arise as to whether the effort of scanning full text articles is worthy, or whether the information that can be extracted from the different sections of an article can be relevant. In this work we addressed those questions showing that the keyword content of the different sections of a standard scientific article (abstract, introduction, methods, results, and discussion) is very heterogeneous. Although the abstract contains the best ratio of keywords per total of words, other sections of the article may be a better source of biologically relevant data.

It discusses its properties and presents some reflections on how the use of social and complex network models can contribute to the diffusion of knowledge. The proposed method presented here is applied to scientific journals where the titles of papers are in English or in Portuguese. We show that the topology of studied semantic networks are small-world and scale-free.

Evaluation of Euthanasia Techniques for an Invertebrate Species, Land Snails (Succinea putris).

PubMed

Gilbertson, Cody R; Wyatt, Jeffrey D

2016-01-01

The euthanasia of invertebrates used in scientific investigations poses unanswered questions regarding the rapid induction of unconsciousness with minimal distress and pain. Relative to vertebrates, invertebrates' sensory experience of pain, nociception, and physiologic response to aversive stimuli are poorly characterized. The scientific communities in the European Union, Canada, United States, Australia, and New Zealand join in consensus regarding the need to address alleviation of pain and distress in cephalopods (octopus, squid, and so forth), which have the best-characterized nervous system among invertebrates. In the current study, we evaluated various euthanasia techniques in a terrestrial gastropod species, with priority on animal wellbeing, scientific variability, feasibility in both field and laboratory settings, and acceptability by personnel. In addition, we demonstrated that the 2-step method of euthanasia described in the AVMA Guidelines as acceptable for aquatic invertebrates is effective for terrestrial snails and meets all welfare and scientific requirements. This 2-step method first induces anesthesia by immersion in 5% ethanol (laboratory-grade ethanol or beer) followed by immersion in a euthanizing and tissue-preserving solution of 70% to 95% ethanol or 10% neutral buffered formalin. Furthermore, alternative methods of euthanasia for terrestrial snails commonly used in field research, such as live immersion in concentrated ethanol or formalin, were shown to be unacceptable.

[Animal experiment, can we replace?

PubMed

Combrisson, H

2017-09-01

Animal experiment is a subject of controversies. Some people, defenders of animals, think that it is not acceptable to use for scientific purposes at the risk of making them suffer or assert that the results obtained with animals are not transposable in the human beings. Others, in particular researchers in biology or medicine, think that the animal models are essential for the biomedical search. This confrontation of the opinions bases largely on an evolution of the place of animals in our society. The regulations authorize the use of animals for scientific purposes but oblige to make it under restrictive conditions. The application of 3Rs - replacement, reduction, and refinement - expressed in 1959 by Russel and Burch is an ethical guide to improve the welfare of animals in research. The alternative methods do not allow, in the present state of the knowledge, to answer all the scientific questions in biology and medicine research. They are, most of the time, complementary methods of the in vivo methods. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Narrative Review of Statistical Reporting Checklists, Mandatory Statistical Editing, and Rectifying Common Problems in the Reporting of Scientific Articles.

PubMed

Dexter, Franklin; Shafer, Steven L

2017-03-01

Considerable attention has been drawn to poor reproducibility in the biomedical literature. One explanation is inadequate reporting of statistical methods by authors and inadequate assessment of statistical reporting and methods during peer review. In this narrative review, we examine scientific studies of several well-publicized efforts to improve statistical reporting. We also review several retrospective assessments of the impact of these efforts. These studies show that instructions to authors and statistical checklists are not sufficient; no findings suggested that either improves the quality of statistical methods and reporting. Second, even basic statistics, such as power analyses, are frequently missing or incorrectly performed. Third, statistical review is needed for all papers that involve data analysis. A consistent finding in the studies was that nonstatistical reviewers (eg, "scientific reviewers") and journal editors generally poorly assess statistical quality. We finish by discussing our experience with statistical review at Anesthesia & Analgesia from 2006 to 2016.

An assessment system for rating scientific journals in the field of ergonomics and human factors.

PubMed

Dul, Jan; Karwowski, Waldemar

2004-05-01

A method for selecting and rating scientific and professional journals representing the discipline of ergonomics and human factors is proposed. The method is based upon the journal list, impact factors and citations provided by the Institute of Scientific Information (ISI), and the journal list published in the Ergonomics Abstracts. Three groups of journals were distinguished. The 'ergonomics journals' focus exclusively on ergonomics and human factors. The 'related journals' focus on other disciplines than ergonomics and human factors, but regularly publish ergonomics/human factors papers. The 'basic journals' focus on other technical, medical or social sciences than ergonomics, but are important for the development of ergonomics/human factors. Journal quality was rated using a maximum of four categories: top quality (A-level), high quality (B-level), good quality (C-level)) and professional (P-level). The above methods were applied to develop the Ergonomics Journal List 2004. A total of 25 'ergonomics journals', 58 'related journals' and 142 'basic journals' were classified.

Scientific method discourses in the construction of 'EMF' science: interests, resources and rhetoric in submissions to a public inquiry.

PubMed

Mercer, David

2002-04-01

Since the late 1970s, there has been considerable debate surrounding the question of whether or not exposures to non-ionizing radiation and electric and magnetic fields (EMF), produced by powerlines and electrical and telecommunications technologies, are harmful to health. Whilst there has been some recent evidence of regulatory fatigue, and attempts to enforce closure, the EMF debate nevertheless still continues. This paper will explore the rôle played by competing images of scientific method in the argumentative strategies used by two of the main protagonists in an Australian public inquiry (held in 1990-91) which investigated the EMF issue: 'Inquiry into Community Needs and High Voltage (132kv and above) Transmission Line Development', the so-called Gibbs Inquiry. Apart from documenting some of the epistemologically intricate features of the EMF controversy, the following discussion will also consider the way scientific method discourses can contribute to enhancing the durability of knowledge claims in legal and regulatory settings.

Gutorova, Nataliya; Batyhina, Olena; Trotska, Maryna

2018-01-01

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.

Big Data promises to change cardiology through a massive increase in the data gathered and analysed; but its impact goes beyond improving incrementally existing methods. The potential of comprehensive data sets for scientific discovery is examined, and its impact on the scientific method generally and cardiology in particular is posited, together with likely consequences for research and practice. Big Data in cardiology changes how new insights are being discovered. For it to flourish, significant modifications in the methods, structures, and institutions of the profession are necessary.

[Scientific stealing (Plagiarism) in medical journals].

PubMed

Enöz, Murat

2007-01-01

The obligation to publish academic papers in order to get academic rank has made medical doctors more ambitious to publish faster and more papers. According to the ethical and legal rules in our country and in the world, if an idea or technical methods of another person is used in a medical journal, the owner of the method or idea and its publication has to be cited. If an idea, information or a technical method of another scientist is published without citation as if it was one's own idea it's called "Plagiarism". Despite the prohibitive laws and rules, this scientific stealing has become an increasing problem for medical journals worldwide.

Steponas Kolupaila's contribution to hydrological science development

NASA Astrophysics Data System (ADS)

Valiuškevičius, Gintaras

2017-08-01

Steponas Kolupaila (1892-1964) was an important figure in 20th century hydrology and one of the pioneers of scientific water gauging in Europe. His research on the reliability of hydrological data and measurement methods was particularly important and contributed to the development of empirical hydrological calculation methods. Kolupaila was one of the first who standardised water-gauging methods internationally. He created several original hydrological and hydraulic calculation methods (his discharge assessment method for winter period was particularly significant). His innate abilities and frequent travel made Kolupaila a universal specialist in various fields and an active public figure. He revealed his multilayered scientific and cultural experiences in his most famous book, Bibliography of Hydrometry. This book introduced the unique European hydrological-measurement and computation methods to the community of world hydrologists at that time and allowed the development and adaptation of these methods across the world.

Methods for the scientific study of discrimination and health: an ecosocial approach.

PubMed

Krieger, Nancy

2012-05-01

The scientific study of how discrimination harms health requires theoretically grounded methods. At issue is how discrimination, as one form of societal injustice, becomes embodied inequality and is manifested as health inequities. As clarified by ecosocial theory, methods must address the lived realities of discrimination as an exploitative and oppressive societal phenomenon operating at multiple levels and involving myriad pathways across both the life course and historical generations. An integrated embodied research approach hence must consider (1) the structural level-past and present de jure and de facto discrimination; (2) the individual level-issues of domains, nativity, and use of both explicit and implicit discrimination measures; and (3) how current research methods likely underestimate the impact of racism on health.

Elaboration and formalization of current scientific knowledge of risks and preventive measures illustrated by colorectal cancer.

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

2007-01-01

Background Teaching the principles of scientific research in a comprehensive way is important at medical and dental schools. In many countries medical and dental training is not complete until the candidate has presented a diploma thesis. The objective of this study was to evaluate the nature, quality, publication pattern and visibility of Finnish medical diploma theses. Methods A total of 256 diploma theses presented at the University of Oulu from 2001 to 2003 were analysed. Using a standardised questionnaire, we extracted several characteristics from each thesis. We used the name of the student to assess whether the thesis resulted in a scientific publication indexed in medical article databases. The number of citations received by each published thesis was also recorded. Results A high proportion of the theses (69.5%) were essentially statistical in character, often combined with an extensive literature review or the development of a laboratory method. Most of them were supervised by clinical departments (55.9%). Only 61 theses (23.8%) had been published in indexed scientific journals. Theses in the fields of biomedicine and diagnostics were published in more widely cited journals. The median number of citations received per year was 2.7 and the range from 0 to 14.7. Conclusion The theses were seldom written according to the principles of scientific communication and the proportion of actually published was small. The visibility of these theses and their dissemination to the scientific community should be improved. PMID:18053247

Ecoacoustic Music for Geoscience: Sonic Physiographies and Sound Casting

NASA Astrophysics Data System (ADS)

Burtner, M.

2017-12-01

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

Distribution of authorship in a scientific work.

PubMed

Petroianu, Andy

2012-01-01

To publish became almost compulsory in Medicine. There is no doubt about the importance of publishing research, but the ordering of its authors is not easy. The lack of internationally accepted criteria led to the establishment of several groups or conventions particularized medical and scientific sectors. To present numerical method to establish rule of value to people who carried out the research, and whether or not incorporated as authors. The proposed score is based on the needs of each step when conducting a scientific work. They were divided into topics in which the main ones were: 1) scientific criteria for authorship; 2) create the idea that originated the work and develop hypotheses; 3) structure the method of work; 4) guiding the work; 5) write the manuscript; 6) coordinate the group that carried out the work; 7) reviewing the literature; 8) suggestions incorporated into the work; 9) to solve fundamental problems of labor; 10) to collect data; 11) presentation at scientific meetings; 12 ) lead the job and raise funds; 13) providing patients or material; 14) to do the routine needs; 15) specific fee to participate; 16) criteria for ranking the authors; 17) honorary author; 18) usurpation of the main authorship, 19) acknowledgments . It is important to emphasize that, to prevent major conflicts, the group that is willing to conduct a scientific work should establish at the outset, as objectively as possible, the criteria to be adopted for distribution of authorship. The subjective criteria here proposed avoid interference and prevent conflicts of interest.

Guidelines for Preparation of a Scientific Paper

Even the experienced scientific writer may have difficulty transferring research results to clear, concise, publishable words. To assist the beginning scientific writer, guidelines are proposed that will provide direction for determining a topic, developing protocols, collecting data, using computers for analysis and word processing, incorporating copyediting notations, consulting scientific writing manuals, and developing sound writing habits. Guidelines for writing each section of a research paper are described to help the writer prepare the title page, introduction, materials and methods, results, and discussion sections of the paper, as well as the acknowledgments and references. Procedures for writing the first draft and subsequent revisions include a checklist of structural and stylistic problems and common errors in English usage. PMID:3339646

Bridging the Gap between Scientific Data Producers and Consumers: A Provenance Approach

Despite the methodical and painstaking efforts made by scientists to record their scientific findings and protocols, a knowledge gap problem continues to persist today between producers of scientific results and consumers because technology is performing the exchange of data as opposed to scientists making direct contact. Provenance is a means to formalize how this knowledge is transferred. However, for it to be meaningful to scientists, the provenance research community needs continued contributions from the scientific community to extend and leverage provenance-based vocabularies and technology from the provenance community. Going forward the provenance community must also be vigilant to meet scalabilitymore » needs of data intensive science« less

The scientific method is capable of being applied in primary care. In this article we defend the role of the "scientific entertainer "as strategic and necessary in achieving this goal. The task has to include playful and light-hearted content. We explore some words in English that may help us to understand the concept of "scientific entertainer" from a semantic point of view (showman, master of ceremonies, entrepreneur, go-between) also in Spanish language (counsellor, mediator, methodologist) and finally in Latin and Greek (tripalium, negotium, chronos, kairos). We define the clinical, manager or research health-worker who is skilled in primary care as a "primarylogist". Copyright © 2011 Elsevier España, S.L. All rights reserved.

Nine Criteria for a Measure of Scientific Output

PubMed Central

Kreiman, Gabriel; Maunsell, John H. R.

2011-01-01

Scientific research produces new knowledge, technologies, and clinical treatments that can lead to enormous returns. Often, the path from basic research to new paradigms and direct impact on society takes time. Precise quantification of scientific output in the short-term is not an easy task but is critical for evaluating scientists, laboratories, departments, and institutions. While there have been attempts to quantifying scientific output, we argue that current methods are not ideal and suffer from solvable difficulties. Here we propose criteria that a metric should have to be considered a good index of scientific output. Specifically, we argue that such an index should be quantitative, based on robust data, rapidly updated and retrospective, presented with confidence intervals, normalized by number of contributors, career stage and discipline, impractical to manipulate, and focused on quality over quantity. Such an index should be validated through empirical testing. The purpose of quantitatively evaluating scientific output is not to replace careful, rigorous review by experts but rather to complement those efforts. Because it has the potential to greatly influence the efficiency of scientific research, we have a duty to reflect upon and implement novel and rigorous ways of evaluating scientific output. The criteria proposed here provide initial steps toward the systematic development and validation of a metric to evaluate scientific output. PMID:22102840

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

Doing laboratory ethnography: reflections on method in scientific workplaces.

PubMed

Stephens, Neil; Lewis, Jamie

2017-04-01

Laboratory ethnography extended the social scientist's gaze into the day-to-day accomplishment of scientific practice. Here we reflect upon our own ethnographies of biomedical scientific workspaces to provoke methodological discussion on the doing of laboratory ethnography. What we provide is less a 'how to' guide and more a commentary on what to look for and what to look at. We draw upon our empirical research with stem cell laboratories and animal houses, teams producing robotic surgical tools, musicians sonifying data science, a psychiatric genetics laboratory, and scientists developing laboratory grown meat. We use these cases to example a set of potential ethnographic themes worthy of pursuit: science epistemics and the extended laboratory, the interaction order of scientific work, sensory realms and the rending of science as sensible, conferences as performative sites, and the spaces, places and temporalities of scientific work.

Routines, roles, and responsibilities for aligning scientific and classroom practices

NASA Astrophysics Data System (ADS)

Ford, Michael J.; Wargo, Brian M.

2007-01-01

Reform efforts in science education have focused on engaging students in authentic scientific practices. For these efforts to succeed, detailed articulations of scientific practice need to be linked to understandings of classroom practice. Here we characterize engagement in practice generally in terms of 3Rs: routines, roles, and responsibilities. We argue that there is a misalignment between the 3Rs of scientific practice and the practices common in classrooms, and that this misalignment poses a considerable obstacle for beginning teachers who attempt to implement reform pedagogy. As part of a secondary methods course, 16 preservice teachers (PSTs) participated in two exemplar activities designed to engage them in scientific practices. The PST performances suggest that at least initially, they did not consider authentic scientific practices appropriate for classroom activities, implying a pedagogical repertoire dominated by the 3Rs of traditional classrooms. PST performances, however, evidenced a shift in the 3Rs from those common in classrooms to those required by these activities, suggesting that their visions for classrooms are malleable and underlining the importance of aligning the 3Rs of scientific and classroom practices during teacher preparation.

Scientific Ethics: A New Approach.

PubMed

Menapace, Marcello

2018-06-04

Science is an activity of the human intellect and as such has ethical implications that should be reviewed and taken into account. Although science and ethics have conventionally been considered different, it is herewith proposed that they are essentially similar. The proposal set henceforth is to create a new ethics rooted in science: scientific ethics. Science has firm axiological foundations and searches for truth (as a value, axiology) and knowledge (epistemology). Hence, science cannot be value neutral. Looking at standard scientific principles, it is possible to construct a scientific ethic (that is, an ethical framework based on scientific methods and rules), which can be applied to all sciences. These intellectual standards include the search for truth (honesty and its derivatives), human dignity (and by reflection the dignity of all animals) and respect for life. Through these it is thence achievable to draft a foundation of a ethics based purely on science and applicable beyond the confines of science. A few applications of these will be presented. Scientific ethics can have vast applications in other fields even in non scientific ones.

Scientific efforts are traditionally published only as articles, with an estimate of millions of publications worldwide per year; the growth rate of PubMed alone is now 1 papers per minute. The validation of scientific results requires reproducible methods, which can only be achieved if the same data, processes, and algorithms as those used in the original experiments were available. However, the problem is that although publications, methods and datasets are very related, they are not always openly accessible and interlinked. Even where data is discoverable, accessible and assessable, significant challenges remain in the reuse of the data, in particular facilitatingmore » the necessary correlation, integration and synthesis of data across levels of theory, techniques and disciplines. In the LISC 2011 (1st International Workshop on Linked Science) we will discuss and present results of new ways of publishing, sharing, linking, and analyzing such scientific resources motivated by driving scientific requirements, as well as reasoning over the data to discover interesting new links and scientific insights. Making entities identifiable and referenceable using URIs augmented by semantic, scientifically relevant annotations greatly facilitates access and retrieval for data which used to be hardly accessible. This Linked Science approach, i.e., publishing, sharing and interlinking scientific resources and data, is of particular importance for scientific research, where sharing is crucial for facilitating reproducibility and collaboration within and across disciplines. This integrated process, however, has not been established yet. Bibliographic contents are still regarded as the main scientific product, and associated data, models and software are either not published at all, or published in separate places, often with no reference to the respective paper. In the workshop we will discuss whether and how new emerging technologies (Linked Data, and semantic technologies more generally) can realize the vision of Linked Science. We see that this depends on their enabling capability throughout the research process, leading up to extended publications and data sharing environments. Our workshop aims to address challenges related to enabling the easy creation of data bundles - data, processes, tools, provenance and annotation - supporting both publication and reuse of the data. Secondly, we look for tools and methods for the easy correlation, integration and synthesis of shared data. This problem is often found in many disciplines (including astronomy, biology, geosciences, cultural heritage, earth, climate, environmental and ecological sciences and impacts etc.), as they need to span techniques, levels of theory, scales, and disciplines. With the advent of Linked Science, it is timely and crucial to address these identified research challenges through both practical and formal approaches.« less

On Establishing Big Data Wave Breakwaters with Analytics (Invited)

NASA Astrophysics Data System (ADS)

Riedel, M.

2013-12-01

The Research Data Alliance Big Data Analytics (RDA-BDA) Interest Group seeks to develop community based recommendations on feasible data analytics approaches to address scientific community needs of utilizing large quantities of data. RDA-BDA seeks to analyze different scientific domain applications and their potential use of various big data analytics techniques. A systematic classification of feasible combinations of analysis algorithms, analytical tools, data and resource characteristics and scientific queries will be covered in these recommendations. These combinations are complex since a wide variety of different data analysis algorithms exist (e.g. specific algorithms using GPUs of analyzing brain images) that need to work together with multiple analytical tools reaching from simple (iterative) map-reduce methods (e.g. with Apache Hadoop or Twister) to sophisticated higher level frameworks that leverage machine learning algorithms (e.g. Apache Mahout). These computational analysis techniques are often augmented with visual analytics techniques (e.g. computational steering on large-scale high performance computing platforms) to put the human judgement into the analysis loop or new approaches with databases that are designed to support new forms of unstructured or semi-structured data as opposed to the rather tradtional structural databases (e.g. relational databases). More recently, data analysis and underpinned analytics frameworks also have to consider energy footprints of underlying resources. To sum up, the aim of this talk is to provide pieces of information to understand big data analytics in the context of science and engineering using the aforementioned classification as the lighthouse and as the frame of reference for a systematic approach. This talk will provide insights about big data analytics methods in context of science within varios communities and offers different views of how approaches of correlation and causality offer complementary methods to advance in science and engineering today. The RDA Big Data Analytics Group seeks to understand what approaches are not only technically feasible, but also scientifically feasible. The lighthouse Goal of the RDA Big Data Analytics Group is a classification of clever combinations of various Technologies and scientific applications in order to provide clear recommendations to the scientific community what approaches are technicalla and scientifically feasible.

Break with tradition: donating cadavers for scientific purposes and reducing the use of sentient beings.

PubMed

Ciliberti, Rosagemma; Martini, Mariano; Bonsignore, Alessandro; Penco, Susanna

2016-01-01

In recent years, the development of research and the increased awareness of our moral duties beyond the human species have pushed the scientific community to revise widely-accepted ontological reductionist views that regard non-human animals as mere things. The new horizons offered by the development of advanced research methods therefore require an on-going commitment to new perspectives able to find the right balance between the need for scientific knowledge on one hand and the respect for animal life on the other. This is in line with increasing attention to animal welfare and expansion of the "3Rs model": replacement, reduction, refinement.With the view of promoting the adoption of alternative methods, human body donation for research can contribute not only to the acquisition of important information for human health and for doctors' training, but also can reduce significantly the number of animals sacrificed.By investigating the scientific and ethical reasons that may encourage cadaver donation, the authors aim to promote the adoption of the practice in Italy following other European experiences.

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

Hormesis, epitaxy, the structure of liquid water, and the science of homeopathy.

PubMed

Mastrangelo, Domenico

2007-01-01

According to the western medical establishment, homeopathy is both "unscientific" and "implausible". A short overview of its history and the methods it uses, however, easily reveals that homeopathy is a true science, fully grounded on the scientific method and on principles, such as, among others, the Arndt-Schultz law, hormesis, and epitaxy, whose plausibility has been clearly and definitely demonstrated in a number of scientific publications and reports. Through a review of the scientific literature, an explanation of the basic principles of homeopathy is proposed based on arguments and evidence of mainstream science to demonstrate that, in spite of the claims of conventional medicine, homeopathy is both scientific and plausible and that there is no reasonable justification for its rejection by the western medical establishment. Hopefully, this hurdle will be overcome by opening academic institutions to homeopathy to enlarge the horizons of medical practice, recover the value of the human relationship with the patient, and through all this, offer the sick a real alternative and the concrete perspective of an improved quality of life.

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.

Understanding the (inter)disciplinary and institutional diversity of citizen science: A survey of current practice in Germany and Austria.

Pettibone, Lisa; Vohland, Katrin; Ziegler, David

2017-01-01

Citizen science has become more popular in recent years, quickly taking on a variety of potentially conflicting characteristics: a way to collect massive data sets at relatively low cost, a way to break science out of the ivory tower and better engage the public, an approach to educate lay people in scientific methods. But the extent of current citizen science practice-the types of actors and scientific disciplines who take part-is still poorly understood. This article builds on recent surveys of citizen science in PLOS One by analyzing citizen science practice in Germany and Austria through the projects on two online platforms. We find evidence supporting previous findings that citizen science is a phenomenon strongest in biodiversity and environmental monitoring research, but at home in a number of scientific fields, such as history and geography. In addition, our survey method yields new insights into citizen science projects initiated by non-scientific actors. We close by discussing additional methodological considerations in attempting to present a cross-disciplinary overview of citizen science.

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.

2006-01-01

Aim To evaluate scientific production among research fellows employed at the Zagreb University School of Medicine and identify factors associated with their scientific output. Method We conducted a survey among research fellows and their mentors during June 2005. The main outcome measure was publication success, defined for each fellow as publishing at least 0.5 articles per employment year in journals indexed in the Current Contents bibliographic database. Bivariate methods and binary logistic regression were used in data analysis. Results A total of 117 fellows (response rate 95%) and 83 mentors (100%) were surveyed. The highest scientific production was recorded among research fellows employed in public health departments (median 3.0 articles, interquartile range 4.0), compared with those from pre-clinical (median 0.0, interquartile range 2.0) and clinical departments (median 1.0, interquartile range 2.0) (Kruskal-Wallis, P = 0.003). A total of 36 (29%) research fellows published at least 0.5 articles per employment year and were considered successful. Three variables were associated with fellows’ publication success: mentor’s scientific production (odds ratio [OR], 3.14; 95% confidence interval [CI], 1.31-7.53), positive mentor’s assessment (OR, 3.15; 95% CI, 1.10-9.05), and fellows’ undergraduate publication in journals indexed in the Current Contents bibliographic database (OR, 4.05; 95% CI, 1.07-15.34). Conclusion Undergraduate publication could be used as one of the main criteria in selecting research fellows. One of the crucial factors in a fellow’s scientific production and career advancement is mentor’s input, which is why research fellows would benefit most from working with scientifically productive mentors.

Students deserve the opportunity to explore the world of science surrounding them. Therefore it is important that scientific exploration and investigation be a part of each student`s educational career. The Department of Energy`s Adventures in Superconducting (AiS) takes students beyond mere scientific literacy to a rich embodiment of scientific exploration. AiS provides today`s science and math students with a greater opportunity to investigate science problems, propose solutions, explore different methods of solving the problem, organize their work into a technical paper, and present their results. Students learn at different rates in different ways. Science classes with students having varying learningmore » styles and levels of achievement have always been a challenge for teachers. The AiS {open_quotes}hands-on, minds-on{close_quotes} project-based method of teaching science meets the challenge of this diversity heads on! AiS uses the development of student chosen projects as the means of achieving a lifelong enthusiasm for scientific proficiency. One goal of AiS is to emulate the research that takes place in the everyday environment of scientists. Students work in teams and often collaborate with students nationwide. With the help of mentors from the academic and scientific community, students pose a problem in science, investigate possible solutions, design a mathematical and computational model for the problem, exercise the model to achieve results, and evaluate the implications of the results. The students then have the opportunity to present the project to their peers, teachers, and scientists. Using this inquiry-based technique, students learn more than science skills, they learn to reason and think -- going well beyond the National Science Education Standard. The teacher becomes a resource person actively working together with the students in their quest for scientific knowledge.« less

In bioinformatics projects, scientific workflow systems are widely used to manage computational procedures. Full-featured workflow systems have been proposed to fulfil the demand for workflow management. However, such systems tend to be over-weighted for actual bioinformatics practices. We realize that quick deployment of cutting-edge software implementing advanced algorithms and data formats, and continuous adaptation to changes in computational resources and the environment are often prioritized in scientific workflow management. These features have a greater affinity with the agile software development method through iterative development phases after trial and error.Here, we show the application of a scientific workflow system Pwrake to bioinformatics workflows. Pwrake is a parallel workflow extension of Ruby's standard build tool Rake, the flexibility of which has been demonstrated in the astronomy domain. Therefore, we hypothesize that Pwrake also has advantages in actual bioinformatics workflows. We implemented the Pwrake workflows to process next generation sequencing data using the Genomic Analysis Toolkit (GATK) and Dindel. GATK and Dindel workflows are typical examples of sequential and parallel workflows, respectively. We found that in practice, actual scientific workflow development iterates over two phases, the workflow definition phase and the parameter adjustment phase. We introduced separate workflow definitions to help focus on each of the two developmental phases, as well as helper methods to simplify the descriptions. This approach increased iterative development efficiency. Moreover, we implemented combined workflows to demonstrate modularity of the GATK and Dindel workflows. Pwrake enables agile management of scientific workflows in the bioinformatics domain. The internal domain specific language design built on Ruby gives the flexibility of rakefiles for writing scientific workflows. Furthermore, readability and maintainability of rakefiles may facilitate sharing workflows among the scientific community. Workflows for GATK and Dindel are available at http://github.com/misshie/Workflows.

Introduction: Human health directly depends on safety and quality of food. In turn, quality and safety of food directly depend on its production conditions and methods. There are two main food production methods: traditional and organic. Organic food production is considered safer and more beneficial for human health. Aim: to determine whether the organic food production method affects human health. 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. The problems of effects of food production methods and conditions on human health have been analyzed within the framework of the system approach. Conclusions: Food production methods and conditions ultimately affect the state and level of human health. The organic method of production activity has a positive effect on human health.

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.

The epistemology of Deep Brain Stimulation and neuronal pathophysiology

PubMed Central

Montgomery, Erwin B.

2012-01-01

Deep Brain Stimulation (DBS) is a remarkable therapy succeeding where all manner of pharmacological manipulations and brain transplants fail. The success of DBS has resurrected the relevance of electrophysiology and dynamics on the order of milliseconds. Despite the remarkable effects of DBS, its mechanisms of action are largely unknown. There has been an expanding catalogue of various neuronal and neural responses to DBS or DBS-like stimulation but no clear conceptual encompassing explanatory scheme has emerged despite the technological prowess and intellectual sophistication of the scientists involved. Something is amiss. If the scientific observations are sound, then why has there not been more progress? The alternative is that it may be the hypotheses that frame the questions are at fault as well as the methods of inference (logic) used to validate the hypotheses. An analysis of the past and current notions of the DBS mechanisms of action is the subject in order to identify the presuppositions (premises) and logical fallacies that may be at fault. The hope is that these problems will be avoided in the future so the DBS can realize its full potential quickly. In this regard, the discussion of the methods of inference and presuppositions that underlie many current notions is no different then a critique of experimental methods common in scientific discussions and consequently, examinations of the epistemology and logic are appropriate. This analysis is in keeping with the growing appreciation among scientists and philosophers of science, the scientific observations (data) to not “speak for themselves” nor is the scientific method self-evidently true and that consideration of the underlying inferential methods is necessary.

The Internet and science communication: blurring the boundaries

PubMed Central

Warden, R

2010-01-01

Scientific research is heavily dependent on communication and collaboration. Research does not exist in a bubble; scientific work must be communicated in order to add it to the body of knowledge within a scientific community, so that its members may ‘stand on the shoulders of giants’ and benefit from all that has come before. The effectiveness of scientific communication is crucial to the pace of scientific progress: in all its forms it enables ideas to be formulated, results to be compared, and replications and improvements to be made. The sharing of science is a foundational aspect of the scientific method. This paper, part of the policy research within the FP7 EUROCANCERCOMS project, discusses how the Internet has changed communication by cancer researchers and how it has the potential to change it still more in the future. It will detail two broad types of communication: formal and informal, and how these are changing with the use of new web tools and technologies. PMID:22276045

The state of rehabilitation research: art or science?

PubMed

Tate, Denise G

2006-02-01

Rehabilitation research has been criticized as not standing up enough to the rigors of scientific method to be called "science." The field has been portrayed as slow to promote its scientific achievements and to include them under the rubric of evidence-based rehabilitation. Following in the footsteps of psychology, rehabilitation as a broad-based discipline has faced many similar obstacles in achieving scientific status. Controversy exists about what exactly constitutes rehabilitation science versus its art and its respective multidisciplinary domains. The conception of these domains is directly related to current methods available to assess the state of the discipline and its research accomplishments. I used quantitative methods, such as randomized clinical and/or controlled trials (RCTs) and systematic reviews, to assess the status of rehabilitation research. Findings suggest that, as a field, rehabilitation makes significant contributions to science, measurable by the number and quality of RCTs and systematic reviews conducted so far on topics of critical importance for clinical care. In "artful" complement, qualitative approaches can be used as research tools to aid investigators in seeking knowledge beyond that obtained by quantitative methods, assessing many complexities associated with the various contexts of rehabilitation research. Other requirements to develop a common vision of rehabilitation science are also discussed.

Eddy covariance and surface renewal measurements were used to estimate evapotranspiration (ET) over a variety of crop fields in the Sacramento-San Joaquin River Delta during the 2016 growing season. However, comparing and evaluating multiple measurement systems and methods for determining ET was focused upon at a single alfalfa site. The eddy covariance systems included two systems for direct measurement of latent heat flux: one using a separate sonic anemometer and an open path infrared gas analyzer and another using a combined system (Campbell Scientific IRGASON). For these methods, eddy covariance was used with measurements from the Campbell Scientific CSAT3, the LI-COR 7500a, the Campbell Scientific IRGASON, and an additional R.M. Young sonic anemometer. In addition to those direct measures, the surface renewal approach included several energy balance residual methods in which net radiation, ground heat flux, and sensible heat flux (H) were measured. H was measured using several systems and different methods, including using multiple fast-response thermocouple measurements and using the temperatures measured by the sonic anemometers. The energy available for ET was then calculated as the residual of the surface energy balance equation. Differences in ET values were analyzed between the eddy covariance and surface renewal methods, using the IRGASON-derived values of ET as the standard for accuracy.

2011-12-01

Since art and science went their separate ways in the 18th century, the purpose of science has been to generate true knowledge based on reason and objectivity. However, during the second half of the 20th century, opinions emerged within science that showed the impossibility of eliminating subjectivity in scientific practice. This paper describes the similarity of the subjective judgements that form part of the peer-review system-the method devised by the scientific community to guarantee truth and objectivity-and the subjective judgements involved in artistic evaluation.

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.

This study is a component of a four-year investigation of MS PHD'S Professional Development Program's virtual community through the lenses of underrepresented minority students in Earth system science and engineering fields. In this presentation, the development, assessment and projected utilization of the ongoing study will be discussed. The overall goal of this study is to examine the effectiveness of virtual team building methods and understand how the development of a communal cyberinfrastructure acts as an integral part of the emergence of a Scientific Renaissance. The exemplar, Minorities Striving and Pursuing Higher Degrees of Success in Earth System Science (MS PHD'S), provides professional development experiences to facilitate the advancement of students of color achieving outstanding Earth system careers. Undergraduate and graduate students are supported through access to scientific conferences, mentorship and virtual community building. Framed by critical theory, this ethnographic exploration uses a mixed methods research design to record, observe, and analyze both the processes and products of the website, listserv and synchronous web-based dialogue. First, key findings of the formative evaluation and annual reports of the successfully implemented 2003 MS PHD'S Pilot Project are presented. These findings inform future evaluations of the use of technological resources and illustrate how this public space provides peer support and enriched research opportunities. Quantitative methods such as statistical analysis, academic and professional tracking and evaluative tools for scientific content and competency are complimented by qualitative methods that include observations, heuristic case studies and focus group interviews. The findings of this ongoing investigation will provide insight on how national organizations, higher education practitioners, community-based support systems and underrepresented minorities in the sciences promote diversity by developing successful cyberspace programs and networks. Through the examination of the transformation, expansion and democratization of the Earth system science community, new knowledge will be obtained on how a cyber-community fuses science, diversity and technology to form dialectics between creating and analyzing a Scientific Renaissance.

Enhancing Science Education Instruction: A Mixed-Methods Study on University and Middle School Collaborations

NASA Astrophysics Data System (ADS)

Owen-Stone, Deborah S.

The purpose of this concurrent mixed methods study was to examine the collaborative relationship between scientists and science teachers and to incorporate and advocate scientific literacy based on past and current educational theories such as inquiry based teaching. The scope of this study included archived student standardized test scores, semi-structured interviews, and a Likert scale survey to include open-ended comments. The methodology was based on the guiding research question: To what extent and in what ways does the collaboration and inquiry methodology, with GTF and PT teams, serve toward contributing to a more comprehensive and nuanced understanding of this predicting relationship between student PASS scores, inquiry skills, and increased scientific literacy for GTF's, PT's, and students via an integrative mixed methods analysis? The data analysis considerations were derived from the qualitative data collected from the three GTF/PT teams by the use of recorded interviews and text answered survey comments. The quantitative data of archived student Palmetto Assessment of State Standards (PASS) scores on scientific literacy and inquiry tests and the Likert-scale portion of the survey were support data to the aforementioned qualitative data findings. Limitations of the study were (1) the population of only the GK-12 teachers and their students versus the inclusion of participants that did not experience the GK-12 Fellow partnerships within their classrooms, should they be considered as participants, (2) involved the researcher as a participant for two years of the program and objectivity remained through interpretation and well documented personal reflections and experiences to inform accuracy, and (3) cultural diversity contributed to the relationship formed between the research Fellow and science educator and communication and scientific language did form a barrier between the Fellow, educator, and student rapport within the classroom. This study's contribution benefits science education, scientists, university science education, and future collaborations. Key Terms: mixed methods, GK-12, scientific literacy, inquiry, collaboration.

Some authors marked a change of perspective from the early to the late Jervis's thought, in terms of a supposed turn towards conservatism. That laid him open to criticism from some Leftist Italian intellectuals. The aim of this paper is to show that conservatism never was a Jervis's thought feature. Mainly, subjects and methods leading the development of his philosophical views suggest a continuity between earlier writings and later ones. All over his thought, in fact, the idea of preeminence of scientific method and historical contextualization convinced him about naturalistic approaches to human behavior, which came to support his Darwinism and laicism in approaching socio-psychological and socio-political issues.

PREDON Scientific Data Preservation 2014

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.

Scientism and Scientific Thinking. A Note on Science Education

NASA Astrophysics Data System (ADS)

Gasparatou, Renia

2017-11-01

The move from respecting science to scientism, i.e., the idealization of science and scientific method, is simple: We go from acknowledging the sciences as fruitful human activities to oversimplifying the ways they work, and accepting a fuzzy belief that Science and Scientific Method, will give us a direct pathway to the true making of the world, all included. The idealization of science is partly the reason why we feel we need to impose the so-called scientific terminologies and methodologies to all aspects of our lives, education too. Under this rationale, educational policies today prioritize science, not only in curriculum design, but also as a method for educational practice. One might expect that, under the scientistic rationale, science education would thrive. Contrariwise, I will argue that scientism disallows science education to give an accurate image of the sciences. More importantly, I suggest that scientism prevents one of science education's most crucial goals: help students think. Many of my arguments will borrow the findings and insights of science education research. In the last part of this paper, I will turn to some of the most influential science education research proposals and comment on their limits. If I am right, and science education today does not satisfy our most important reasons for teaching science, perhaps we should change not just our teaching strategies, but also our scientistic rationale. But that may be a difficult task.

Methods for the Scientific Study of Discrimination and Health: An Ecosocial Approach

PubMed Central

2012-01-01

The scientific study of how discrimination harms health requires theoretically grounded methods. At issue is how discrimination, as one form of societal injustice, becomes embodied inequality and is manifested as health inequities. As clarified by ecosocial theory, methods must address the lived realities of discrimination as an exploitative and oppressive societal phenomenon operating at multiple levels and involving myriad pathways across both the life course and historical generations. An integrated embodied research approach hence must consider (1) the structural level—past and present de jure and de facto discrimination; (2) the individual level—issues of domains, nativity, and use of both explicit and implicit discrimination measures; and (3) how current research methods likely underestimate the impact of racism on health.

2018-01-01

In order to evaluate the development level of the low-voltage distribution network objectively and scientifically, chromatography analysis method is utilized to construct evaluation index model of low-voltage distribution network. Based on the analysis of principal component and the characteristic of logarithmic distribution of the index data, a logarithmic centralization method is adopted to improve the principal component analysis algorithm. The algorithm can decorrelate and reduce the dimensions of the evaluation model and the comprehensive score has a better dispersion degree. The clustering method is adopted to analyse the comprehensive score because the comprehensive score of the courts is concentrated. Then the stratification evaluation of the courts is realized. An example is given to verify the objectivity and scientificity of the evaluation method.

Introduction: Despite the extraordinary progress made in the field of vaccination, a large number of children in the last decade, 24 million children, or nearly 20% of children born every year, do not receive a full plan for vaccination during their first year of life. The aim: The purpose of the article is to analyze the legal framework of vaccination in Ukraine, comparing the approach of the domestic legislator to the vaccination with foreign experience. Materials and methods: Methods of research are selected based on the goal of the study. In order to establish the objectivity and validity of scientific statements and conclusions, during the conducted research a complex of general scientific and special scientific methods was used, in particular such as: the formal legal method; comparative legal method; the method of forecasting and modeling; historical-legal method. Review: In countries with epidemics, a state of emergency can be established and quarantine measures and vaccination to exercise the right to collective health, which may limit the right to individual health by limiting the right to consent to vaccination. Conclusions: It is concluded that in world practice there is no single approach to the recognition of the right to vaccination, as a human right, or as a duty to preserve the epidemiological security of the state. It has been proved that infectious diseases evolve, change their form, the only effective means of preventing pandemics, which may question the existence of man as a biological species, is the vaccination system.

Phase-Transition-Induced Pattern Formation Applied to Basic Research on Homeopathy: A Systematic Review.

2018-05-16

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

Scientific consensus, the law, and same sex parenting outcomes.

PubMed

adams, Jimi; Light, Ryan

2015-09-01

While the US Supreme Court was considering two related cases involving the constitutionality of same-sex marriage, one major question informing that decision was whether scientific research had achieved consensus regarding how children of same-sex couples fare. Determining the extent of consensus has become a key aspect of how social science evidence and testimony is accepted by the courts. Here, we show how a method of analyzing temporal patterns in citation networks can be used to assess the state of social scientific literature as a means to inform just such a question. Patterns of clustering within these citation networks reveal whether and when consensus arises within a scientific field. We find that the literature on outcomes for children of same-sex parents is marked by scientific consensus that they experience "no differences" compared to children from other parental configurations.

Laboratory ethnography extended the social scientist’s gaze into the day-to-day accomplishment of scientific practice. Here we reflect upon our own ethnographies of biomedical scientific workspaces to provoke methodological discussion on the doing of laboratory ethnography. What we provide is less a ‘how to’ guide and more a commentary on what to look for and what to look at. We draw upon our empirical research with stem cell laboratories and animal houses, teams producing robotic surgical tools, musicians sonifying data science, a psychiatric genetics laboratory, and scientists developing laboratory grown meat. We use these cases to example a set of potential ethnographic themes worthy of pursuit: science epistemics and the extended laboratory, the interaction order of scientific work, sensory realms and the rending of science as sensible, conferences as performative sites, and the spaces, places and temporalities of scientific work.

Opportunities and benefits as determinants of the direction of scientific research.

Scientific research and private-sector technological innovation differ in objectives, constraints, and organizational forms. Scientific research may thus not be driven by the direct practical benefit to others in the way that private-sector innovation is. Alternatively, some - yet largely unexplored - mechanisms drive the direction of scientific research to respond to the expected public benefit. We test these two competing hypotheses of scientific research. This is important because any coherent specification of what constitutes the socially optimal allocation of research requires that scientists take the public practical benefit of their work into account in setting their agenda. We examine whether the composition of medical research responds to changes in disease prevalence, while accounting for the quality of available research opportunities. We match biomedical publications data with disease prevalence data and develop new methods for estimating the quality of research opportunities from textual information and structural productivity parameters.

PREFACE: 21th International Conference for Students and Young Scientists: Modern Technique and Technologies (MTT'2015)

NASA Astrophysics Data System (ADS)

2015-10-01

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.

Plagiarism in Scientific Research and Publications and How to Prevent It

Quality is assessed on the basis of adequate evidence, while best results of the research are accomplished through scientific knowledge. Information contained in a scientific work must always be based on scientific evidence. Guidelines for genuine scientific research should be designed based on real results. Dynamic research and use correct methods of scientific work must originate from everyday practice and the fundamentals of the research. The original work should have the proper data sources with clearly defined research goals, methods of operation which are acceptable for questions included in the study. When selecting the methods it is necessary to obtain the consent of the patients/respondents to provide data for execution of the project or so called informed consent. Only by the own efforts can be reached true results, from which can be drawn conclusions and which finally can give a valid scholarly commentary. Text may be copied from other sources, either in whole or in part and marked as a result of the other studies. For high-quality scientific work necessary are expertise and relevant scientific literature, mostly taken from publications that are stored in biomedical databases. These are scientific, professional and review articles, case reports of disease in physician practices, but the knowledge can also be acquired on scientific and expert lectures by renowned scientists. Form of text publications must meet standards on writing a paper. If the article has already been published in a scientific journal, the same article cannot be published in any other journal with a few minor adjustments, or without specifying the parts of the first article which is used in another article. Copyright infringement occurs when the author of a new article, with or without mentioning the author, uses a substantial portion of previously published articles, including past contributions in the first article. With the permission of the publisher and the author, another journal can re-publish the article already published. In that case, that is not plagiarism, because the journal states that the article was re-published with the permission of the journal in which the article is primarily released. The original can be only one, and the copy is a copy, and plagiarism is stolen copy. The aim of combating plagiarism is to improve the quality, to achieve satisfactory results and to compare the results of their own research, rather than copying the data from the results of other people's research. Copy leads to incorrect results. Nowadays the problem of plagiarism has become huge, or widespread and present in almost all spheres of human activity, particularly in science. Scientific institutions and universities should have a center for surveillance, security, promotion and development of quality research. Establishment of rules and respect the rules of good practice are the obligations of each research institutions, universities and every individual researchers, regardless of which area of science is being investigated. There are misunderstandings and doubts about the criteria and standards for when and how to declare someone a plagiarist. European and World Association of Science Editors (EASE and WAME), and COPE - Committee on Publishing Ethics working on the precise definition of that institution or that the scientific committee may sanction when someone is proven plagiarism and familiarize the authors with the types of sanctions. The practice is to inform the editors about discovered plagiarism and articles are withdrawn from the database, while the authors are put on the so-called black list. So far this is the only way of preventing plagiarism, because there are no other sanctions. PMID:24944543
