  1. Understanding the composite practice that forms when classrooms take up the practice of scientific argumentation

    Science.gov (United States)

    Kuhn Berland, Leema

    Traditional classroom practices communicate epistemic commitments and goals that might be contrary to those needed for meaningful participation in scientific inquiry practices. In this dissertation, I explore how traditional classroom practices influence students' participation in the practice of scientific argumentation. I address this through a two-pronged approach. First, given that students do not typically engage in collaborative knowledge-building through scientific argumentation, I used the best-practices put forth by relevant research to support teachers in facilitating this practice. Second, I worked with four classes as they enacted a unit designed to foster scientific argumentation. I observed the emergent class discussions and engaged in discourse analysis in which I related the interaction patterns found in non-argumentative class discussions to those that occurred in lessons designed to foster scientific argumentation. Examining the argumentative discussions reveals that each class transformed the practice in different ways. Comparing these interactions to those of the non-argumentative suggests that students used the goals and beliefs that guided their typical classroom practices to interpret the activity structures for and teacher's framings of the new practice of scientific argumentation. In this dissertation, I present a research methodology for understanding the relationship between typical classroom practices and student adaptations of new scientific practices; design strategies for supporting scientific argumentation; and a framework for understanding how and why classroom communities adapt the practice of scientific argumentation.

    The objectives of this qualitative study were to understand the experience of the nursing dependent person for the bed-bath and develop a theoretical model of this experience. The Symbolic Interactionism perspective and Grounded Theory methodology were used to develop the study. Observation and interview were the strategies used for data collection. Based on data analysis, a phenomenon was identified: learning to assess life and nursing when the patient becomes dependent on nursing care for the bed-bath. The theoretical model shows the meaning of the patient experience in the bed-bath, integrated by the core category--proposing a nursing model for the bed-bath according to the patient assessment process, as opposed to the technical-scientific evolution of this procedure.

  4. Mundane science use in a practice theoretical perspective: Different understandings of the relations between citizen-consumers and public communication initiatives build on scientific claims.

    Public communication initiatives play a part in placing complicated scientific claims in citizen-consumers' everyday contexts. Lay reactions to scientific claims framed in public communication, and attempts to engage citizens, have been important subjects of discussion in the literatures of public understanding and public engagement with science. Many of the public communication initiatives, however, address lay people as consumers rather than citizens. This creates specific challenges for understanding public engagement with science and scientific citizenship. The article compares five different understandings of the relations between citizen-consumers and public issue communication involving science, where the first four types are widely represented in the Public Understanding of Science discussions. The fifth understanding is a practice theoretical perspective. The article suggests how the public understanding of and engagement in science literature can benefit from including a practice theoretical approach to research about mundane science use and public engagement. © The Author(s) 2015.

  5. Collaboration in scientific practice

    Wagenknecht, Susann

    2014-01-01

    This monograph investigates the collaborative creation of scientific knowledge in research groups. To do so, I combine philosophical analysis with a first-hand comparative case study of two research groups in experimental science. Qualitative data are gained through observation and interviews......, and I combine empirical insights with existing approaches to knowledge creation in philosophy of science and social epistemology. On the basis of my empirically-grounded analysis I make several conceptual contributions. I study scientific collaboration as the interaction of scientists within research...... groups. Thereby, I argue that research groups and their role in scientific practice deserve more philosophical attention than they have hitherto received. In contemporary natural science, research groups are key to the formulation and corroboration of scientific knowledge claims prior...

    Full Text Available Scientific models represent ideas, processes, and phenomena by describing important components, characteristics, and interactions. Models are constructed across various scientific disciplines, such as the food web in biology, the water cycle in Earth science, or the structure of the solar system in astronomy. Models are central for scientists to understand phenomena, construct explanations, and communicate theories. Constructing and using models to explain scientific phenomena is also an essential practice in contemporary science classrooms. Our research explores new techniques for understanding scientific modeling and engagement with modeling practices. We work with students in secondary biology classrooms as they use a web-based software tool—EcoSurvey—to characterize organisms and their interrelationships found in their local ecosystem. We use learning analytics and machine learning techniques to answer the following questions: (1 How can we automatically measure the extent to which students’ scientific models support complete explanations of phenomena? (2 How does the design of student modeling tools influence the complexity and completeness of students’ models? (3 How do clickstreams reflect and differentiate student engagement with modeling practices? We analyzed EcoSurvey usage data collected from two different deployments with over 1,000 secondary students across a large urban school district. We observe large variations in the completeness and complexity of student models, and large variations in their iterative refinement processes. These differences reveal that certain key model features are highly predictive of other aspects of the model. We also observe large differences in student modeling practices across different classrooms and teachers. We can predict a student’s teacher based on the observed modeling practices with a high degree of accuracy without significant tuning of the predictive model. These results highlight

The workshop was organized around five research areas with associated panels. Three of these, "High Energy Theoretical Physics," "Accelerator Simulation," and "Experimental Particle Physics," addressed research of the Office of High Energy Physics’ Energy and Intensity Frontiers, while the"Cosmology and Astrophysics Simulation" and "Astrophysics Data Handling, Archiving, and Mining" panels were associated with the Cosmic Frontier.

  11. Practical approaches to scientific presentation.

    Lin, Y C

    1989-01-01

    Oral presentation differs from written presentation in that listening audience has a limited time to comprehend the subject matter. Speakers in scientific meetings use slides to facilitate transfer of information, because methods and results are best explained using drawings, figures, and tables. Schematic drawings, tables, and figures that appear in print usually contain too much detail to suit oral presentation. Presentation slides should allow the audience to grasp the contents quickly. Good slides attract attention, invite retention and cross language barriers. Regardless of language and style used, oral scientific presentation emphasizes information transfer, explanation of complex matters in the simplest possible way, and logical sequence; all of these can and should be learned by every scientist.

    2017-02-01

    The purposes of this study were to investigate teacher’s perception about scientific argumentation and how they practice it in their classroom. Thirty biology teachers in high school participated in this study and illustrated their perception of scientific argumentation through a questionnaire. This survey research was developed to measure teachers’ understanding of scientific argumentation, what they know about scientific argumentation, the differentiation between argument and reasoning, how they plan teaching strategies in order to make students’ scientific argumentation better and the obstacles in teaching scientific argumentation. The result conclude that generally, teachers modified various representation to accommodate student’s active participation, but most of them assume that argument and reasoning are similar. Less motivation, tools and limited science’s knowledge were considered as obstacles in teaching argumentation. The findings can be helpful to improving students’ abilities of doing scientific argumentation as a part of inquiry.

    2015-01-01

    Do you believe that the roles your employees play on your medical practice team are identical to their job titles or job descriptions? Do you believe that team roles are determined by personality type? This article suggests that a more effective way to build and manage your medical practice team is to define team roles through employee behaviors. It provides 10 rules of behavioral team roles that can help practice managers to select and build high-performing teams, build more productive team relationships, improve the employee recruitment process, build greater team trust and understanding; and increase their own effectiveness. This article describes in detail Belbin's highly regarded and widely used team role theory and summarizes four additional behavioral team role theories and systems. It offers lessons learned when applying team role theory to practice. Finally, this article offers an easy-to-implement method for assessing current team roles. It provides a simple four-question checklist that will help practice managers balance an imbalanced medical practice team.

    Regidor, Enrique

    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.

  20. Measurements of student understanding on complex scientific reasoning problems

    Science.gov (United States)

    Izumi, Alisa Sau-Lin

    While there has been much discussion of cognitive processes underlying effective scientific teaching, less is known about the response nature of assessments targeting processes of scientific reasoning specific to biology content. This study used multiple-choice (m-c) and short-answer essay student responses to evaluate progress in high-order reasoning skills. In a pilot investigation of student responses on a non-content-based test of scientific thinking, it was found that some students showed a pre-post gain on the m-c test version while showing no gain on a short-answer essay version of the same questions. This result led to a subsequent research project focused on differences between alternate versions of tests of scientific reasoning. Using m-c and written responses from biology tests targeted toward the skills of (1) reasoning with a model and (2) designing controlled experiments, test score frequencies, factor analysis, and regression models were analyzed to explore test format differences. Understanding the format differences in tests is important for the development of practical ways to identify student gains in scientific reasoning. The overall results suggested test format differences. Factor analysis revealed three interpretable factors---m-c format, genetics content, and model-based reasoning. Frequency distributions on the m-c and open explanation portions of the hybrid items revealed that many students answered the m-c portion of an item correctly but gave inadequate explanations. In other instances students answered the m-c portion incorrectly yet demonstrated sufficient explanation or answered the m-c correctly and also provided poor explanations. When trying to fit test score predictors for non-associated student measures---VSAT, MSAT, high school grade point average, or final course grade---the test scores accounted for close to zero percent of the variance. Overall, these results point to the importance of using multiple methods of testing and of

    2010-12-01

    A scientific explanation for a phenomenon is based on relevant theory and initial and background conditions. Scientific understanding, on the other hand, requires intelligibility, which means that a scientist can recognise qualitative characteristic consequences of the theory without doing the actual calculations, and apply it to develop further explanations and predictions. If explanation and understanding are indeed fundamentally different, then it may be possible to convey understanding of earth-scientific phenomena to laymen without the full theoretical background. The aim of this thesis is to analyze how scientists and laymen gain scientific understanding in Earth Sciences, based on the newest insights in the philosophy of science, pedagogy, and science communication. All three disciplines have something to say about how humans learn and understand, even if at very different levels of scientists, students, children or the general public. If different disciplines with different approaches identify and quantify the same theory in the same manner, then there is likely to be something “real” behind the theory. Comparing methodology and learning styles of the different disciplines within the Earth Sciences and by critically analyze earth-scientific exhibitions in different museums may provide insight in the different approaches for earth-scientific explanation and communication. In order to gain earth-scientific understanding, a broad suite of tools is used, such as maps and images, symbols and diagrams, cross-sections and sketches, categorization and classification, modelling, laboratory experiments, (computer) simulations and analogies, remote sensing, and fieldwork. All these tools have a dual nature, containing both theoretical and embodied components. Embodied knowledge is created by doing the actual modelling, intervening in experiments and doing fieldwork. Scientific practice includes discovery and exploration, data collection and analyses, verification

    The Vet Futures Report has identified 'exceptional leadership' as a key ambition for the long-term sustainability of the industry. This research investigates what it is like to be a veterinary surgeon in an in-practice leadership position, applying the qualitative methodology of interpretative phenomenological analysis. Through the researchers' interpretation of the seven participants' stories of their leadership experiences, the study advances understanding of the work environment, underlying motivations and the perceived responsibilities of veterinary leaders. Findings suggest, for many, a struggle in transition to leader positions, improving with time. The increase in pace of work is relayed by participants, with an ongoing, and unchallenged, work-life imbalance. The vets involved are highly motivated, driven by enjoyment of their jobs, a desire for self-determination and a need to make a difference. Relationships form the core of the perceived responsibilities, and yet are identified as the greatest day-to-day challenge of leadership. This study offers a valuable insight for veterinary surgeons, suggesting the industry could benefit from pausing and reflecting on behaviours. With a greater understanding of the complexity of leadership and followership, progress can be made to enact positive changes for the future. © British Veterinary Association (unless otherwise stated in the text of the article) 2018.

    Full Text Available The sharing of scientific data is a problem that attracts worldwide attention. In answer, governments have started to establish many systems to provide the public with scientific data. However, sometimes the access does not consider the public's practical need but just stands as an "official" prototype. In this research, a questionnaire was devised to understand a Beijing citizen's practical need for scientific data and to explore the inconsistency between the needs of the public and the information published by the government. The research looks to find a more effective way to solve this problem.

    Professor Duzheng YE's name has been familiar to me ever since my postdoctoral years at MIT with Professors Jule CHARNEY and Norman PHILLIPS, back in the late 1960s. I had the enormous pleasure of meeting Professor YE personally in 1992 in Beijing. His concern to promote the very best science and to use it well, and his thinking on multi-level orderly human activities, reminds me not only of the communication skills we need as scientists but also of the multi-level nature of science itself. Here I want to say something (a) about what science is; (b) about why multi-level thinking—and taking more than one viewpoint—is so important for scientific as well as for other forms of understanding; and (c) about what is meant, at a deep level, by "scientific understanding" and trying to communicate it, not only with lay persons but also across professional disciplines. I hope that Professor YE would approve.

    Directory of Open Access Journals (Sweden)

    Rein Vihalemm

    2012-12-01

    Full Text Available In this paper, the elaboration of the concept of practical realist philosophy of science which began in the author's previous papers is continued. It is argued that practical realism is opposed to standard scientific realism, on the one hand, and antirealism, on the other. Standard scientific realism is challengeable due to its abstract character, as being isolated from practice. It is based on a metaphysical-ontological presupposition which raises the problem of the God's Eye point of view (as it was called by Hilary Putnam. Joseph Rouse's conception of science as practice, Sami Pihlström's pragmatic realism, and even Ilkka Niiniluoto's critical scientific realism are interpreted as practical realist conceptions. Pihlström suggests that the contemporary scientific realist should be prepared to accept the pragmatically naturalized Kantian transcendental perspective on realism. It is argued, however, that this realistically naturalized Kantianism can be nothing more than practical realism, as originated by Karl Marx.

    Sezen-Barrie, Asli; Moore, Joel; Roig, Cara E.

    2015-08-01

    Drawn from the norms and rules of their fields, scientists use variety of practices, such as asking questions and arguing based on evidence, to engage in research that will contribute to our understanding of Earth and beyond. In this study, we explore how preservice teachers' learn to teach scientific practices while teaching plate tectonic theory. In particular, our aim is to observe which scientific practices preservice teachers use while teaching an earth science unit, how do they integrate these practices into their lessons, and what challenges do they face during their first time teaching of an earth science content area integrated with scientific practices. The study is designed as a qualitative, exploratory case study of seven preservice teachers while they were learning to teach plate tectonic theory to a group of middle school students. The data were driven from the video records and artifacts of the preservice teachers' learning and teaching processes as well as written reflections on the teaching. Intertextual discourse analysis was used to understand what scientific practices preservice teachers choose to integrate into their teaching experience. Our results showed that preservice teachers chose to focus on four aspects of scientific practices: (1) employing historical understanding of how the theory emerged, (2) encouraging the use of evidence to build up a theory, (3) observation and interpretation of data maps, and (4) collaborative practices in making up the theory. For each of these practices, we also looked at the common challenges faced by preservice teachers by using constant comparative analysis. We observed the practices that preservice teachers decided to use and the challenges they faced, which were determined by what might have come as in their personal history as learners. Therefore, in order to strengthen preservice teachers' background, college courses should be arranged to teach important scientific ideas through scientific practices

    2017-06-01

    The Next-Generation Science Standards (NGSS) challenge primary teachers and students to work and think like scientists and engineers as they strive to understand complex concepts. Teachers and teacher educators can leverage what is already known about inquiry teaching as they plan instruction to help students meet the new standards. This cross-case analysis of a multiple case study examined teacher practices in the context of a semester-long professional development course for elementary teachers. We reviewed lessons and teacher reflections, examining how kindergarten and first grade teachers incorporated NGSS scientific and engineering practices during inquiry-based instruction. We found that most of the teachers worked with their students on asking questions; planning and carrying out investigations; analyzing and interpreting data, using mathematics and computational thinking; and obtaining, evaluating and communicating information. Teachers faced challenges in supporting students in developing their own questions that could be investigated and using data collection strategies that aligned with students' development of number sense concepts. Also, some teachers overemphasized the scientific method and lacked clarity in how they elicited and responded to student predictions. Discussion focuses on teacher supports that will be needed as states transition to NGSS.

    Nanotechnology has reached a level where almost every new development and even every new product uses features of nanoscopic properties of materials. As a consequence, an enormous amount of scientific instruments is used in order to synthesize and analyze new structures and materials. Due to the surface sensitivity of such materials, many of these instruments require ultrahigh vacuum that has to be provided under extreme conditions like very high voltages. In this book, Yoshimura provides a review of the UHV related development during the last decades. His very broad experience in the design enables him to present us this detailed reference. After a general description how to design UHV systems, he covers all important issue in detail, like pumps, outgasing, Gauges, and Electrodes for high voltages. Thus, this book serves as reference for everybody using UVH in his scientific equipment

    Twine, Richard

    2015-11-01

    This article approaches snacking from a practice theory perspective in order to understand how this reframing may afford new insights. In doing so it also contributes to sociological thinking on eating practices and their reproduction as well as reflecting upon the ontological assertions of practice theory and its theory of social change. In particular this article argues that the re-conceptualisation serves to clarify a sociological research agenda for eating practices associated with snacking. It is argued that setting snacking within routine temporalities and spatialities and as bound up in the recursivity between practices and relations is especially important for thinking about snacking sociologically. In common with applications of practice theory in the field of sustainability transitions the aim is to move beyond individualistic assumptions of behaviour change and instead situate snacking as an eating practice with health implications that has emerged within the social, temporal, economic and cultural organisation of everyday life. © 2015 Foundation for the Sociology of Health & Illness.

  18. Understanding Teacher Practice using their own Narratives

    This paper discusses ways of understanding teacher practice in educational settings. An educational setting consists of cultural, social and historical elements that all influence the teacher’s practice and, how she experiences this practice. It is argued that teaching science and technology...... their knowledge of teaching, but they willingly tell their experiences from being a teacher. Therefore it is argued that narratives and life history of teachers can give insight into teachers experience, knowledge and practice. The notion of habitus is used to merge the former experience with the actual practice...... is a socially conditioned practice. The teachers’ practice are formed by their previous education and experience but also influenced by their private life. This way of looking at teacher knowledge and experience requires attention to teachers’ perception of these aspects. Teachers seldom talk about...

    Computers are now essential in all branches of science, but most researchers are never taught the equivalent of basic lab skills for research computing. As a result, data can get lost, analyses can take much longer than necessary, and researchers are limited in how effectively they can work with software and data. Computing workflows need to follow the same practices as lab projects and notebooks, with organized data, documented steps, and the project structured for reproducibility, but researchers new to computing often don't know where to start. This paper presents a set of good computing practices that every researcher can adopt, regardless of their current level of computational skill. These practices, which encompass data management, programming, collaborating with colleagues, organizing projects, tracking work, and writing manuscripts, are drawn from a wide variety of published sources from our daily lives and from our work with volunteer organizations that have delivered workshops to over 11,000 people since 2010.

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

  1. Teachers' scientific knowledge, teaching practice, and students' learning activities: Cases of three elementary classroom teachers

    Jang, Shinho

    The purposes of this dissertation study are to better understand what specific types of scientific knowledge and practice three elementary teachers exhibit, and to examine how they use their scientific knowledge in their classroom teaching practice to provide students' opportunities to learn science when teaching condensation in the context of a unit on the water cycle. By comparing and contrasting three cases of elementary classroom teaching, this study discusses what kinds of scientific knowledge and practice are fundamental for teaching elementary science for scientific understanding. The data include structured interviews (content, pre- and post- observation, and stimulated recall), videotaped classroom observations, and collections of teachers' and students' written artifacts. Data were collected prior to, during, and after the three teachers taught condensation to fifth grade students. The data were analyzed in three contexts: interviews, teaching practices, and students' classroom activities. This made it possible to clarify which characteristics of teacher's scientific knowledge influenced which aspects of their teaching practice. Data analysis shows that teachers' scientific knowledge were closely associated with their teaching practice and students' classroom activities. Two characteristics of the teachers' scientific reasoning emerged as especially important. The first concerned how teachers connected observations of condensation with patterns in those observations (e.g., condensation occurs when warm moist air cools) and with explanations for those patterns (e.g., condensation is water vapor that changes to liquid water). Two teachers were careful to connect observations with patterns in their own thinking and in their classroom teaching. One of those teachers also connected the observations and patterns to scientific explanations. In contrast, the third teacher focused on listing scientific terms with little elaboration with specific observations and

    Full Text Available Introduction:The practices of e-science and the use and reuse of scientific data have constituted a new scientific work that leads to the reflection on new regulatory, legal, institutional and technological frameworks for open science. Objective: This study shows the following research question: which dimensions provide sustainability for the formulation of a policy geared to open science and its practices in the Brazilian context? The aim of this study is to discuss the dimensions that support transversely the formulation of a policy for open science and its scientific practices. Methodology:Theoretically, the study is guided by the fourth scientific paradigm grounded in the e-Science. The methodology is supported by Bufrem’s studies (2013, which propose an alternative and multidimensional model for analysis and discussion of scientific research. Technically, the literature review and documentary survey were the methods used on the Data Lifecycle scientific model, laws and international agreements.For this study purpose, five dimensions were proposed, namely: epistemological, political, ethical-legal-cultural, morphological, and technological. Results: This studyunderstands that these dimensions substantiate an information policy or the development of minimum guidelines for the open science agenda in Brazil. Conclusions: The dimensions put away the reductionist perspective on survey data and they conducted the study for the multi-dimensional and multi-relational vision of open science.

    New approaches for teaching and assessing scientific inquiry and practices are essential for guiding students to make the informed decisions required of an increasingly complex and global society. The Science Skills approach described here guides students to develop an understanding of the experimental skills required to perform a scientific investigation. An individual teacher's investigation of the strategies and tools she designed to promote scientific inquiry in her classroom is outlined. This teacher-driven action research in the high school biology classroom presents a simple study design that allowed for reciprocal testing of two simultaneous treatments, one that aimed to guide students to use vocabulary to identify and describe different scientific practices they were using in their investigations-for example, hypothesizing, data analysis, or use of controls-and another that focused on scientific collaboration. A knowledge integration (KI) rubric was designed to measure how students integrated their ideas about the skills and practices necessary for scientific inquiry. KI scores revealed that student understanding of scientific inquiry increased significantly after receiving instruction and using assessment tools aimed at promoting development of specific inquiry skills. General strategies for doing classroom-based action research in a straightforward and practical way are discussed, as are implications for teaching and evaluating introductory life sciences courses at the undergraduate level.

  5. A social epistemology of research groups collaboration in scientific practice

    CERN Document Server

    Wagenknecht, Susann

    2016-01-01

    This book investigates how collaborative scientific practice yields scientific knowledge. At a time when most of today’s scientific knowledge is created in research groups, the author reconsiders the social character of science to address the question of whether collaboratively created knowledge should be considered as collective achievement, and if so, in which sense. Combining philosophical analysis with qualitative empirical inquiry, this book provides a comparative case study of mono- and interdisciplinary research groups, offering insight into the day-to-day practice of scientists. The book includes field observations and interviews with scientists to present an empirically-grounded perspective on much-debated questions concerning research groups’ division of labor, relations of epistemic dependence and trust.

    Full Text Available Research evaluates the development of scientific initiation among Basic Level students as they are stimulated to experience cognitive processes in the production of knowledge. Such processes are a strategy to build significant knowledge. Informal teaching (non-formal and outside of the classroom activities contributes to education outside the borders of the classroom promoting experiments that allow greater development and creativity through an interactive type of learning. Carrying out research and presenting its results, make young scholars improve their communication skills as well as allows them to exchange and build new conceptions about scientific knowledge. Thus, they are able to acquire an integral vision and understanding of the world. Reality is unveiled through information, knowledge, technique and theory based on social demand rather than their imposition on society. Demand for knowledge and use of theory and practice have a dialectic relationship

    2012-12-01

    Full Text Available The objective of this article is to show how the production of scientific diffusion texts from a Portuguese textbook used in high schools is taught. The research questions are: (1 how is the scientific diffusion sphere presented to the student? (2 Which is the linguistic-discursive treatment that the authors offer to lead the student to the production of scientific diffusion texts? (3 How do these procedures help improve writing in the most varied genres in the scientific sphere? A didactic activity involving written production of a text for scientific diffusion from the textbook series Português: contexto, interlocução e sentido was chosen. The analysis is based on the concept of text as postulated by Bakhtin and the Circle, for whom the text is a real unit of discursive communication. The result shows that the activity does not materialize the Bakhtinian theoretical bases adopted in the teacher’s manual. In the dialogic perspective, in order to insert the student in the writing practices of scientific texts, it is necessary to make him/her take on the role of reader of journals and specialized magazines, as well as the role of scientist/researcher.

  9. Scientific literacy: Role of natural history studies in constructing understanding of the nature of science

    2002-01-01

    Scientific literacy is a central goal of science education. One purpose of this investigation was to reevaluate the definition of 'scientific literacy.' Another purpose was to develop and implement new curriculum involving natural history experiments with insects, with the goal of allowing students opportunities to construct an understanding of the nature of science, a crucial aspect of scientific literacy. This investigation was a qualitative case study. Methods of data collection included direct observations, analysis of sketches and written products created by students and class-room teachers, and analysis of audio tapes. Major findings include: (1) Scientific literacy is generally defined by lists of factual information which students are expected to master. When asked to evaluate their knowledge of selected items on a list published in a science education reform curriculum guide, 15 practicing scientists reported lack of familiarity or comprehension with many items, with the exception of items within their areas of specialization. (2) Genuine natural history experiments using insects can be incorporated into the existing school schedule and need not require any increase in the budget for science materials. (3) Students as young as first through third grade can learn the manual techniques and conceptual skills necessary for designing and conducting original natural history experiments, including manipulating the insects, making accurate sketches, developing test able hypotheses, recording data, and drawing conclusions from their data. Students were generally enthusiastic both about working with live insects and also conducting genuine science experiments. (4) Girls appear both positive and engaged with natural history activities and may be more likely than boys to follow through on designing, conducting, and reporting on independent experiments. The results imply that a valid definition of scientific literacy should be based on the ability to acquire scientific

    2014-05-01

    Background: In Bangladesh, a common science curriculum caters for all students at the junior secondary level. Since this curriculum is for all students, its aims are both to build a strong foundation in science while still providing students with the opportunities to use science in everyday life - an aim consistent with the notion of scientific literacy. Purpose: This paper reports Bangladeshi science teachers' perspectives and practices in regard to the promotion of scientific literacy. Sample: Six science teachers representing a range of geographical locations, school types with different class sizes, lengths of teaching experience and educational qualifications. Design and method: This study employed a case study approach. The six teachers and their associated science classes (including students) were considered as six cases. Data were gathered through observing the teachers' science lessons, interviewing them twice - once before and once after the lesson observation, and interviewing their students in focus groups. Results: This study reveals that participating teachers held a range of perspectives on scientific literacy, including some naïve perspectives. In addition, their perspectives were often not seen to be realised in the classroom as for teachers the emphasis of learning science was more traditional in nature. Many of their teaching practices promoted a culture of academic science that resulted in students' difficulty in finding connections between the science they study in school and their everyday lives. This research also identified the tension which teachers encountered between their religious values and science values while they were teaching science in a culture with a religious tradition. Conclusions: The professional development practice for science teachers in Bangladesh with its emphasis on developing science content knowledge may limit the scope for promoting the concepts of scientific literacy. Opportunities for developing pedagogic

    2010-06-01

    The scientific publishing practices of the pharmaceutical industry have been heavily criticized in recent years due to the inherent conflict of interest that arises when a pharmaceutical company publishes findings around its own drugs. Eli Lilly and Company ('Lilly') strives for transparency in its day-to-day activities, and, here, shares its principles, policies and practices on publishing "Lilly-sponsored" research. A conflict of interest does not necessarily equate to biased presentation of research findings, and operating a successful, for-profit business and maintaining a focus on improving the health of patients are not mutually exclusive goals. There is, however, potential for bias, and it is incumbent upon a for-profit to develop publication principles, policies and practices to address this. To this end, Lilly's Principles of Medical Research states that 'Lilly discloses publicly all medical research results that are important to patients, healthcare providers or payers--whether favorable or unfavorable to a Lilly product--in an accurate, objective, and balanced manner ...' The preparation of publications of Lilly-sponsored research involves close collaboration between external (i.e., academic or otherwise non-industry employees) and Lilly scientific researchers (including scientific writers), with both serving as authors. Lilly does not support 'ghost' or 'guest' authorship. Authorship is not just recognition of contribution but also public acknowledgement of responsibility for content, and all authors are expected to take an active role in developing the manuscript in line with the International Committee of Medical Journal Editors-based authorship requirements. This is agreed to by authors before the manuscript is started. Lilly provides external authors with access to the trial data for manuscript development. Lilly does not pay external authors for their involvement in manuscript development. Scientific writers at Lilly, often with advanced scientific

    2017-12-01

    The need for the highest levels of scientific integrity and ethical principles in higher education, globally, is obvious. This is the setting where faculty scientists practice and future scientists, as entering science majors, those who change course and switch to science, and graduate students, are nurtured and mentored. Institutions of higher education across the globe are devoting increasing attention to scientific integrity and ethical practices, often as mandated by specific (funding) agencies, and this certainly is a step in the right direction. One approach has involved graduate students, particularly PhD students, in formal classes/seminars on the subjects. Another, more institution-specific, is to require freshman science majors to take one or more classes designed to assist students, in many ways, to succeed in whatever science path they choose. For the past five years I have "taught" such a class, which I like to refer to as "Science is the Rest of Your Life 101". My section is very heavy on scientific integrity and ethical practices; most students have never been exposed to nor have considered such subjects. Their interest level is exceedingly keen. So, steps are being taken, but rectifying existing concerns will take time. Here are some (potential/real) problems. One facing all of higher education is the ever decreasing number, certainly in the United States, of tenured/tenure track faculty in all disciplines together with the generational "gap" or "double gap" (some colleagues of mine are in their 80s) between those who never for all intents and purposes received any "formal" exposure to scientific integrity and ethical practices issues and those fresh in the academy for which these subjects are recently and better engrained. At most institutions, those faculty never involved in such formal training because of, well, their age, are required to pass some form of on-line "certification" class in research ethics among other subjects on an annual or bi

    On Saturday morning, February 28, 1953, the mystery of heredity appeared secure. Humans hadn't the faintest idea of how genetic information was transmitted-how the uncanny resemblance between mother and daughter, grandfather and grandson was conveyed across generations. Yet, by that Saturday afternoon, two individuals, James Watson and Francis Crick, had glimpsed the solution to these mysteries. The story of Watson and Crick's great triumph has been told and retold and has rightly entered the pantheon of scientific legend. But Watson and Crick's breakthrough was just that: a rupture and dramatic discontinuity in human knowledge that solved a deep mystery, the likes of which occurs, perhaps, a couple of times each century. And that's the problem. The story is just so good and so irresistible that it has misled generations of scientists about what to expect regarding a life in science. And more damaging, the resulting breakthrough mentality misleads the public, the media, and society's decision-makers about how science really works, all to the detriment of scientific progress and our society's well-being. © 2016 The Hastings Center.

    Science.gov (United States)

    Buskila, Dan

    2009-01-01

    Our understanding of fibromyalgia (FM) has made significant advances over the past decade. The current concept views FM as the result of central nervous system malfunction resulting in amplification of pain transmission and interpretation. Research done over the past years has demonstrated a role for polymorphisms of genes in the serotoninergic, dopaminergic and catecholaminergic systems in the etiopathogenesis of FM. Various external stimuli such as infection, trauma and stress may contribute to the development of the syndrome. The management of FM requires an integrated approach combining pharmacological and nonpharmacological modalities. The recent Food and Drugs Administration approval of pregabalin, duloxetine and milnacipran as medications for FM may herald a new era for the development of medications with higher specificity and efficacy for the condition. As our understanding of the biological basis and the genetic underpinning of FM increases, we hope to gain a better understanding of the true nature of the disorder, to better classify patients and to attain more rational therapeutic modalities.

    2014-12-01

    Given that K-12 students have numerous alternative conceptions, it is critical that teachers have an understanding of the fundamental science underlying climate change (Feldman et al., 2010). Many teachers, however, do not demonstrate adequate understanding of these concepts (Daskolia et al., 2006). Argumentation has been identified as a mechanism for conceptual change (Mercer et al., 2004). Even with several educational initiatives promoting and supporting the use of argumentation as an instructional practice, teachers often struggle to implement argumentation in the classroom (Sampson & Blanchard, 2012). To remedy both issues above, we have designed an innovative methods course to provide background in climate change knowledge and argumentation instruction. In our methods course, we utilize Climate Science Investigations (CSI), an online, interactive series of modules and teaching resources funded by a NASA grant to support teachers learning about the basic science concepts underlying climate change. A key assignment is to develop and present an evidence-based scientific argument. The teachers were assigned a typical question and claim of climate skeptics and asked to conduct research on the scientific findings to prepare a counter-argument (rebuttal). This study examined changes in 60 preservice teachers' knowledge and perceptions about climate change after participation in the course. The teachers' understanding of fundamental concepts increased significantly. Their perceptions about climate change became more aligned to those of climate scientists. Findings suggest that scientific argumentation can play an effective role in the preparation of science educators. In addition to reporting findings in more detail, methods course activities, particularly in argumentation, will be shared in our presentation.

    their understandings of following aspects of scientific inquiry: (a) the iterative nature of scientific inquiry; (b) the tentativeness of specific knowledge claims; (c) the degree to which scientists rely on empirical data, as well as broader conceptual and metaphysical commitments, to assess models and to direct future inquiries; (d) the need for conceptual consistency; (e) multiple methods of investigations and multiple interpretations of data; and (f) social and cultural aspects of scientific inquiry. This research provided evidence that hypothesis testing can support the integrated acquisition of conceptual and procedural knowledge in science. Participants' conceptual elaborations of Mendelian inheritance were enhanced. There were qualitative changes in the nature of the participants' explanations. Moreover, the average percentage of correct responses improved from 39% on the pretest to 67% on the posttest. Findings also suggest those prospective science teachers' experiences as learners of science in their methods course served as a powerful tool for thinking about the role of inquiry in teaching and learning science. They had mixed views about enacting inquiry in their teaching in the future. All of them stated some kind of general willingness to do so; yet, they also mentioned some reservations and practical considerations about inquiry-based teaching.

    2017-01-01

    The NASA Ames Life Sciences Institutional Scientific Collection (ISC), which is composed of the Ames Life Sciences Data Archive (ALSDA) and the Biospecimen Storage Facility (BSF), is managed by the Space Biosciences Division and has been operational since 1993. The ALSDA is responsible for archiving information and animal biospecimens collected from life science spaceflight experiments and matching ground control experiments. Both fixed and frozen spaceflight and ground tissues are stored in the BSF within the ISC. The ALSDA also manages a Biospecimen Sharing Program, performs curation and long-term storage operations, and makes biospecimens available to the scientific community for research purposes via the Life Science Data Archive public website (https:lsda.jsc.nasa.gov). As part of our best practices, a viability testing plan has been developed for the ISC, which will assess the quality of archived samples. We expect that results from the viability testing will catalyze sample use, enable broader science community interest, and improve operational efficiency of the ISC. The current viability test plan focuses on generating disposition recommendations and is based on using ribonucleic acid (RNA) integrity number (RIN) scores as a criteria for measurement of biospecimen viablity for downstream functional analysis. The plan includes (1) sorting and identification of candidate samples, (2) conducting a statiscally-based power analysis to generate representaive cohorts from the population of stored biospecimens, (3) completion of RIN analysis on select samples, and (4) development of disposition recommendations based on the RIN scores. Results of this work will also support NASA open science initiatives and guides development of the NASA Scientific Collections Directive (a policy on best practices for curation of biological collections). Our RIN-based methodology for characterizing the quality of tissues stored in the ISC since the 1980s also creates unique

    Full Text Available Spasticity is a poorly understood phenomenon. The aim of this paper is to understand the effect of spasticity on daily life and identify bedside strategies that enhance patient’s function and improve comfort. Spasticity and clonus result from an upper motor neuron lesion that disinhibits the tendon stretch reflex; however, they are differentiated in the fact that spasticity results in a velocity dependent tightness of muscle whereas clonus results in uncontrollable jerks of the muscle. Clinical strategies that address function and comfort are paramount. This is a secondary content analysis using a qualitative research design. Adults experiencing spasticity associated with neuromuscular disorder were asked to participate during inpatient acute rehabilitation. They were asked to complete a semistructured interview to explain and describe the nature of their experienced spasticity on daily basis. Spasticity affects activities of daily living, function, and mobility. Undertreated spasticity can lead to pain, immobility, and risk of falls. There were missed opportunities to adequately care for patients with spasticity. Bedside care strategies identified by patients with spasticity are outlined. Uses of alternative therapies in conjunction with medications are needed to better manage spasticity. Patient reports on spasticity are important and should be part of clinical evaluation and practice.

    2008-01-01

    To understand the feeding practices, knowledge, and nutritional beliefs of Vietnamese mothers with young children who are recent immigrants to the United States. Exploratory, descriptive study using a focus group design to provide qualitative data. Twelve Vietnamese mothers of children under the age of 5 years participated in a 1-hour focus group discussion (in Vietnamese) facilitated by a Vietnamese nutritionist and the principal investigator. The study participants identified that breastfeeding is healthier for babies than formula but reported the difficulty in maintaining breastfeeding due to work and family constraints. A traditional Vietnamese diet of meat or fish with soup broth, vegetables, and rice was the preferred and healthiest diet for children under the age of 6 years. There was consensus in the group that "junk food" and inactivity were unhealthy for children and led to overweight and obesity. Several of the group participants verbalized difficulty in maintaining a healthy diet for their children because the children demanded unhealthy food choices, and their work schedules made it difficult to make sure their children were getting adequate exercise. This knowledge can be used by nurses to develop culturally appropriate interventions for immigrants from Vietnam aimed at preventing childhood obesity. Interventions that consider the effects of acculturation could be more effective when targeted to parents of young children than interventions focused on treatment of obesity in later years.

  2. On Understanding: Maxwell on the Methods of Illustration and Scientific Metaphor

    Science.gov (United States)

    Cat, Jordi

    In this paper I examine the notion and role of metaphors and illustrations in Maxwell's works in exact science as a pathway into a broader and richer philosophical conception of a scientist and scientific practice. While some of these notions and methods are still at work in current scientific research-from economics and biology to quantum computation and quantum field theory-, here I have chosen to attest to their entrenchment and complexity in actual science by attempting to make some conceptual sense of Maxwell's own usage; this endeavour includes situating Maxwell's conceptions and applications in his own culture of Victorian science and philosophy. I trace Maxwell's notions to the formulation of the problem of understanding, or interpreting, abstract representations such as potential functions and Lagrangian equations. I articulate the solution in terms of abstract-concrete relations, where the concrete, in tune with Victorian British psychology and engineering, includes the muscular as well as the pictorial. This sets the basis for a conception of understanding in terms of unification and concrete modelling, or representation. I examine the relation of illustration to analogies and metaphors on which this account rests. Lastly, I stress and explain the importance of context-dependence, its consequences for realism-instrumentalism debates, and Maxwell's own emphasis on method.

  3. The pallid sturgeon: Scientific investigations help understand recovery needs

    2010-01-01

    Understanding of the pallid sturgeon (Scaphirhynchus albus) has increased significantly since the species was listed as endangered over two decades ago. Since 2005, scientists at the U.S. Geological Survey (USGS) Columbia Environmental Research Center (CERC) have been engaged in an interdisciplinary research program in cooperation with the U.S. Army Corps of Engineers Missouri River Recovery Program, U.S. Fish and Wildlife Service, Nebraska Game and Parks Commission, and numerous other State and Federal cooperators to provide managers and policy makers with the knowledge needed to evaluate recovery options. During that time, the USGS has worked collaboratively with river scientists and managers to develop methods, baseline information, and research approaches that are critical contributions to recovery success. The pallid sturgeon is endangered throughout the Missouri River because of insufficient reproduction and survival of early life stages. Primary management actions on the Missouri River designed to increase reproductive success and survival have focused on flow regime, channel morphology, and propagation. The CERC research strategies have, therefore, been designed to examine the linkages among flow regime, re-engineered channel morphology, and reproductive success and survival.

  7. Investigating Assessment Bias for Constructed Response Explanation Tasks: Implications for Evaluating Performance Expectations for Scientific Practice

    Science.gov (United States)

    Federer, Meghan Rector

    Assessment is a key element in the process of science education teaching and research. Understanding sources of performance bias in science assessment is a major challenge for science education reforms. Prior research has documented several limitations of instrument types on the measurement of students' scientific knowledge (Liu et al., 2011; Messick, 1995; Popham, 2010). Furthermore, a large body of work has been devoted to reducing assessment biases that distort inferences about students' science understanding, particularly in multiple-choice [MC] instruments. Despite the above documented biases, much has yet to be determined for constructed response [CR] assessments in biology and their use for evaluating students' conceptual understanding of scientific practices (such as explanation). Understanding differences in science achievement provides important insights into whether science curricula and/or assessments are valid representations of student abilities. Using the integrative framework put forth by the National Research Council (2012), this dissertation aimed to explore whether assessment biases occur for assessment practices intended to measure students' conceptual understanding and proficiency in scientific practices. Using a large corpus of undergraduate biology students' explanations, three studies were conducted to examine whether known biases of MC instruments were also apparent in a CR instrument designed to assess students' explanatory practice and understanding of evolutionary change (ACORNS: Assessment of COntextual Reasoning about Natural Selection). The first study investigated the challenge of interpreting and scoring lexically ambiguous language in CR answers. The incorporation of 'multivalent' terms into scientific discourse practices often results in statements or explanations that are difficult to interpret and can produce faulty inferences about student knowledge. The results of this study indicate that many undergraduate biology majors

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

    2015-01-01

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

    2018-03-01

    The quality by design (QbD) paradigm guides the pharmaceutical industry towards improved understanding of products and processes, and at the same time facilitates a high degree of manufacturing and regulatory flexibility throughout the establishment of the design space. This review article presents scientific, statistical and regulatory considerations in design space development. All key development milestones, starting with planning, selection of factors, experimental execution, data analysis, model development and assessment, verification, and validation, and ending with design space submission, are presented and discussed. The focus is especially on frequently ignored topics, like management of factors and CQAs that will not be included in experimental design, evaluation of risk of failure on design space edges, or modeling scale-up strategy. Moreover, development of a design space that is independent of manufacturing scale is proposed as the preferred approach.

  1. Collaborative Assessment Tool (CAT) - Assessing scientific practices in introductory physics

    Irving, Paul

    2017-01-01

    An important learning goal of Projects and Practices in Physics (P3) , the transformed introductory mechanics course at Michigan State University, is the development of scientific practices. The design team, as part of the P3 course construction, made clear attempts to assess learning goals that can often be perceived as being a part of the hidden curriculum or considered difficult to assess (e.g., learning to work productively in a group) by developing a collaborative assessment tool (CAT). The CAT is a formative assessment tool that provides students with a numerical grade for how they participated in their learning group on a weekly basis while also providing feedback in the form of written commentary and suggestions on how they might improve at a particular collaborative practice. In this presentation, we demonstrate the CAT tool from two perspectives: 1) how the CAT tool is used within the P3 context and 2) how the formative feedback has affected changes in student interactions in class. We will present the case studies of 3 students who had differing reactions to the feedback they received. We will explore the role the feedback had in their interactions over a four-week period from an in-class perspective and a reflected perspective through interviews and observations. The analysis will also be presented from a tutor and group perspective, which will highlight the affordances the CAT can have in creating a productive learning group. The research on the CAT shows promise in encouraging growth in students' collaborative skills, but this research is still in its infancy and needs to be expanded to include different contexts.

    Cook, N.G.W.; Tsang, C.F.

    1990-01-01

    The development and safety evaluation of a nuclear waste geologic repository require a proper scientific understanding of the site response. Such scientific understanding depends on information from a number of geoscience disciplines, including geology, geophysics, geochemistry, geomechanics and hydrogeology. The information comes in four stages: (1) general regional survey data base, (2) surface-based testing, (3) exploratory shaft testing, and (4) repository construction and evaluation. A discussion is given on the dynamic use of the information through the different stages. We point out the need for abstracting, deriving and updating a quantitative spatial and process model (QSPM) to develop a scientific understanding of site responses as a crucial element in the dynamic procedure. 2 figs

    Do social cognition and epistemological understanding promote elementary school children's experimentation skills? To investigate this question, 402 children (ages 8, 9, and 10) in 2nd, 3rd, and 4th grades were assessed for their experimentation skills, social cognition (advanced theory of mind [AToM]), epistemological understanding (understanding the nature of science), and general information-processing skills (inhibition, intelligence, and language abilities) in a whole-class testing procedure. A multiple indicators multiple causes model revealed a significant influence of social cognition (AToM) on epistemological understanding, and a McNemar test suggested that children's development of AToM is an important precursor for the emergence of an advanced, mature epistemological understanding. Children's epistemological understanding, in turn, predicted their experimentation skills. Importantly, this relation was independent of the common influences of general information processing. Significant relations between experimentation skills and inhibition, and between epistemological understanding, intelligence, and language abilities emerged, suggesting that general information processing contributes to the conceptual development that is involved in scientific thinking. The model of scientific thinking that was tested in this study (social cognition and epistemological understanding promote experimentation skills) fitted the data significantly better than 2 alternative models, which assumed nonspecific, equally strong relations between all constructs under investigation. Our results support the conclusion that social cognition plays a foundational role in the emergence of children's epistemological understanding, which in turn is closely related to the development of experimentation skills. Our findings have significant implications for the teaching of scientific thinking in elementary school and they stress the importance of children's epistemological understanding in

  6. Influence of student-designed experiments with fast plants on their understanding of plants and of scientific inquiry

    Akey, Ann Kosek

    2000-10-01

    This dissertation investigates the influence of student designed experiments with Fast Plants in an undergraduate agroecology course on the students' conceptual understanding of plant life cycles and on their procedural understanding of scientific experimentation. It also considers students' perspectives on the value of these experiences. Data sources included semi-structured interviews with students and the instructor, a written task, course evaluations, and observations of class meetings. Students came into the course having strong practical experience with plants from their agricultural backgrounds. Students did not always connect aspects of plant biology that they studied in class, particularly respiration and photosynthesis, to plant growth requirements. The instructor was able to bridge the gap between some practical knowledge and textbook knowledge with experiences other than the Fast Plant project. Most students held an incomplete picture of plant reproduction that was complicated by differences between agricultural and scientific vocabulary. There is need for teaching approaches that help students tie together their knowledge of plants into a cohesive framework. Experiences that help students draw on their background knowledge related to plants, and which give students the opportunity to examine and discuss their ideas, may help students make more meaningful connections. The Fast Plant project, a positive experience for most students, was seen by these undergraduate students as being more helpful in learning about scientific experimentation than about plants. The process of designing and carrying out their own experiments gave students insight into experimentation, provoked their curiosity, and resulted in a sense of ownership and accomplishment.

  8. What can scientific practice look like in a classroom? Insights from scientists' critique of high school students' climate change argumentation practice

    Science.gov (United States)

    Walsh, E.; McGowan, V. C.

    2015-12-01

    The Next Generation Science Standards promote a vision in which learners engage in authentic knowledge in practice to tackle personally consequential science problems in the classroom. However, there is not yet a clear understanding amongst researchers and educators of what authentic practice looks like in a classroom and how this can be accomplished. This study explores these questions by examining interactions between scientists and students on a social media platform during two pilot enactments of a project-based curriculum focusing on the ecological impacts of climate change. During this unit, scientists provided feedback to students on infographics, visual representations of scientific information meant to communicate to an audience about climate change. We conceptualize the feedback and student work as boundary objects co-created by students and scientists moving between the school and scientific contexts, and analyze the structure and content of the scientists' feedback. We find that when giving feedback on a particular practice (e.g. argumentation), scientists would provide avenues, critiques and questions that incorporated many other practices (e.g. data analysis, visual communication); thus, scientists encouraged students to participate systemically in practices instead of isolating one particular practice. In addition, scientists drew attention to particular habits of mind that are valued in the scientific community and noted when students' work aligned with scientific values. In this way, scientists positioned students as capable of participating "scientifically." While traditionally, incorporating scientific inquiry in a classroom has emphasized student experimentation and data generation, in this work, we found that engaging with scientists around established scientific texts and data sets provided students with a platform for developing expertise in other important scientific practices during argment construction.

  9. MOLECULAR GASTRONOMY IN FUNCTION OF SCIENTIFIC IMPLEMENTATION IN PRACTICE

    2011-12-01

    Full Text Available Modern culinary direction - molecular gastronomy is very complex, and the relative youth of that direction affects the ignorance of the matter by a large number of professionals and the general public. It is precisely this lack of matter which causes a number of disagreements between chefs and scientists, while there is a number of related debates about aspects of molecular gastronomy, especially in connection with a change in its gastronomic cuisine. The main focus of disagreement lies in the name of ''molecular'', which mostly leads to a misunderstanding, because of the identification with something microscopic. A very common mistake is to address this branch of gastronomy as a style of cooking, which she doesn't represent. The second mistake is naming its practical application of molecular cooking, molecular cuisine. Molecular gastronomy is a scientific discipline that studies food and asks questions and gives answers so far unanswered questions about gastronomy. Simply put, molecular gastronomy can be understood as a process of application of science in everyday cooking, and the application of molecular gastronomy in the kitchen. Modern man with his awareness made some chefs to reconsider the adoption of these radical ideas to accomplish the fusion of science and gastronomy. This idea is established as a full hit, because today the best restaurants in the world, the vast majority of those who have seen the benefits of these two joints before incompatible branches of human activity. As a culinary direction it quickly spread to Western Europe and North America, and it later spread to other parts of the world, but Croatia and neighboring countries are not one of them. Molecular gastronomy shows the trends of further progress, and in the future molecular gastronomy will be more prevalent and popular.

    Measures of research productivity are increasingly used to determine how research should be evaluated and funding decisions made. In psychiatry, citation patterns within and between countries are not known, and whether these differ by choice of citation metric. In this study, we examined publication characteristics and citation practices in articles published in 50 Web of Science indexed psychiatric and relevant clinical neurosciences journals, between January 2004 and December 2009 comprising 51,072 records that produced 375,962 citations. We compared citation patterns, including self-citations, between countries using standard x(2) tests. We found that most publications came from the USA, with Germany being second and UK third in productivity. USA articles received most citations and the highest citation rate with an average 11.5 citations per article. The UK received the second highest absolute number of citations, but came fourth by citation rate (9.7 citations/article), after the Netherlands (11.4 citations/article) and Canada (9.8 citations/article). Within the USA, Harvard University published most articles and these articles were the most cited, on average 20.0 citations per paper. In Europe, UK institutions published and were cited most often. The Institute of Psychiatry/Kings College London was the leading institution in terms of number of published records and overall citations, while Oxford University had the highest citation rate (18.5 citations/record). There were no differences between the self-citation practices of American and European researchers. Articles that examined some aspect of treatment in psychiatry were the most published. In terms of diagnosis, papers about schizophrenia-spectrum disorders were the most published and the most cited. We found large differences between and within countries in terms of their research productivity in psychiatry and clinical neuroscience. In addition, the ranking of countries and institutions differed widely

  13. Understanding the Dialectical Relations Between Everyday Concepts and Scientific Concepts Within Play-Based Programs

    Fleer, Marilyn

    2009-03-01

    In recent times there has been an enormous interest in Vygotsky’s writing on conceptual development, particularly his insights on the differences between everyday and scientific thinking. In drawing upon cultural-historical theory, this paper seeks to examine the relations between everyday concepts and scientific concepts within playful contexts, such as preschools, with a view to better understanding how very young children develop conceptual understandings in science. This paper presents an overview of a study which sought to map the transformation and appropriation of scientific concepts within two early childhood settings. Approximately ten weeks of data gathering took place, with video recordings, field notes, photographic documentation, and child and teacher interviews for recording child concept formation within these naturalistic settings. The findings indicate that when teacher programs are more oriented towards concepts rather than materials, children’s play is focused on conceptual connections. Importantly, the study showed that: It was possible to map the multiple and dynamic levels or stratas of thinking that a child or group of children may exhibit within play-based contexts; An analysis of ‘unorganised heaps’ and ‘complexive thinking’ evident in conceptually or materially oriented play-based programs can be determined; the dialectical relations between everyday concepts and scientific concepts in play-based programs can be understood; and greater understanding about the nature of concept formation in situated playful contexts have been possible.

  16. Scientific Understanding: Lacey's `Critical Self-Consciousness' Seen as Echoes of J.D. Bernal

    Science.gov (United States)

    Cross, Roger T.

    From a consideration of the nature of scientific understanding and the control of nature Lacey proposes a set of criteria by which the reform of science teaching might be guided. He uses the term critical self-consciousness to describe the development of learner's appreciation of the character of scientific activity, its applications, and the choices citizens face in society. By this latter he means responsible participation, presumably in the debates surrounding the character of scientific activity, its applications, and the choices inherent in these. In this paper I show that Lacey's vision of the schooling of science through the development of critical self-consciousness has been articulated by others at different epochs, and probably from different ideological perspectives. Knowledge of these will help Lacey in his search for an education in science which promotes citizens' participation rather than alienating them from decision-making in society.

  17. Instructional games: Scientific language use, concept understanding, and attitudinal development of middle school learners

    Science.gov (United States)

    Mongillo, Geraldine

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

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

    Science.gov (United States)

    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.

    Steiner, Jordan J; Kynn, Jamie; Stylianou, Amanda M; Postmus, Judy L

    2018-01-01

    Human trafficking is a global issue, with survivors representing all genders, ages, races, ethnicities, religions, and countries. However, little research exists that identifies effective practices in supporting survivors of human trafficking. The research that does exist is Western-centric. To fill this gap in the literature, the goal of this research was to understand practices used throughout the globe with adult human trafficking survivors. A qualitative approach was utilized. Providers from 26 countries, across six different continents, were interviewed to allow for a comprehensive and multi-faceted understanding of practices in working with survivors. Participants identified utilizing an empowerment-based, survivor, and human life-centered approach to working with survivors, emphasized the importance of engaging in community level interventions, and highlighted the importance of government recognition of human trafficking. Findings provide information from the perspective of advocates on best practices in the field that can be used by agencies to enhance human trafficking programming.

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

    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.

    Abrams, Brian

    2010-01-01

    The American Music Therapy Association has recently put into action a plan called its Research Strategic Priority, with one of its central purposes to advance the music therapy field through research promoting Evidence-Based Practice of music therapy. The extant literature on music therapy practice, theory, and research conveys a range of very different perspectives on what may count as the "evidence" upon which practice is based. There is therefore a need to conceptualize evidence-based music therapy practice in a multifaceted, yet coherent and balanced way. The purpose of this paper is to illustrate a framework based upon four distinct epistemological perspectives on evidence-based music therapy practice that together represent an integral understanding.

    Kinser, Patricia A; Lewis, Judith A

    2005-05-01

    An understanding of imposed cultural norms allows the scientist, researcher, and health care practitioner to move beyond the social construction of gender and illness. From Aristotle's theory of reproduction to neurological and psychological research asserting sex as destiny to present-day attitudes toward intersexuality, we can trace the conceptualization of women in terms of biological inferiority. These theories elucidate the ways in which the cultural assumptions influence the institution of scientific inquiry and vice versa. To assure equal and fair health care practices, a paradigm shift is called for that actively accepts feminist research practices and rejects culturally dominant methods of research in medicine and science.

  5. Publication Ethics and the Emerging Scientific Workforce: Understanding ‘Plagiarism’ in a Global Context

    Cameron, Carrie; Zhao, Hui; McHugh, Michelle K.

    2013-01-01

    Scientific publication has long been dominated by the English language and is rapidly moving towards near complete hegemony of English, while the majority of the world’s publishing scientists are not native English speakers. This imbalance has important implications for training in and enforcement of publication ethics, particularly with respect to plagiarism. A lack of understanding of what constitutes plagiarism and the use of a linguistic support strategy known as patchwriting can lead to inadvertent misuse of source material by non-native speakers writing in English as well as to unfounded accusations of intentional scientific misconduct on the part of these authors. A rational and well-informed dialogue about this issue is needed among both native English speaking and non-native English speaking writers, editors, educators, and administrators. Recommendations for educating and training are provided. PMID:22104051

  6. Implementation of Good Laboratory Practices (GLP) in basic scientific research: Translating the concept beyond regulatory compliance.

    Jena, G B; Chavan, Sapana

    2017-10-01

    The principles of Good Laboratory Practices (GLPs) are mainly intended for the laboratories performing studies for regulatory compliances. However, today GLP can be applied to broad disciplines of science to cater to the needs of the experimental objectives, generation of quality data and assay reproducibility. Considering its significance, it can now be applied in academics; industries as well as government set ups throughout the world. GLP is the best way to promote the reliability, reproducibility of the test data and hence facilitates the international acceptability. Now it is high time to translate and implement the concept of GLP beyond regulatory studies. Thus, it can pave the way for better understanding of scientific problems and help to maintain a good human and environmental health. Through this review, we have made an attempt to explore the uses of GLP principles in different fields of science and its acceptability as well as looking for its future perspectives.

  11. Characterizing Students' Attempts to Explain Observations from Practical Work: Intermediate Phases of Understanding

    Science.gov (United States)

    Mestad, Idar; Kolstø, Stein Dankert

    2017-10-01

    This study aims to characterize a group of students' preliminary oral explanations of a scientific phenomenon produced as part of their learning process. The students were encouraged to use their own wordings to test out their own interpretation of observations when conducting practical activities. They presented their explanations orally in the whole class after having discussed and written down an explanation in a small group. The data consists of transcribed video recordings of the presented explanations, observation notes, and interviews. A genre perspective was used to characterize the students' explanations together with analysis of the students use of scientific terms, gestures, and the language markers "sort of" and "like." Based on the analysis we argue to separate between event-focused explanations, where the students describe how objects move, and object-focused explanations, where the students describe object properties and interactions. The first type uses observable events and few scientific terms, while the latter contains object properties and tentative use of scientific terms. Both types are accompanied by an extensive use of language markers and gestures. A third category, term-focused explanations, is used when the students only provide superficial explanations by expressing scientific terms. Here, the students' use of language markers and gestures are low. The analyses shows how students' explanations can be understood as tentative attempts to build on their current understanding and observations while trying to reach out for a deeper and scientific way of identifying observations and building explanations and new ways of talking.

    Bressler, Denise M.; Bodzin, Alec M.

    2016-10-01

    Mobile serious educational games (SEGs) show promise for promoting scientific practices and high engagement. Researchers have quantified this engagement according to flow theory. This study investigated whether a mobile SEG promotes flow experience and scientific practices with eighth-grade urban students. Students playing the game ( n = 59) were compared with students in a business-as-usual control activity ( n = 120). In both scenarios, students worked in small teams. Data measures included an open-ended instrument designed to measure scientific practices, a self-report flow survey, and classroom observations. The game players had significantly higher levels of flow and scientific practices compared to the control group. Observations revealed that game teams received less whole-class instruction and review compared to the control teams. Game teachers had primarily a guide-on-the-side role when facilitating the game, while control teachers predominantly used didactic instruction when facilitating the control activity. Implications for these findings are discussed.

  17. Understanding the Conceptual and Language Challenges Encountered by Grade 4 Students When Writing Scientific Explanations

    Seah, Lay Hoon

    2016-06-01

    This study is an attempt to examine the use of linguistic resources by primary science students so as to understand the conceptual and language demands encountered by them when constructing written explanations. The students' written explanations and the instructional language (whole-class discussion and textbook) employed over the topic, the life cycle of plants, in four grade 4 classrooms (age 10) taught by three teachers constitute the data for this study. Students' written explanations were subjected to a combination of content and linguistic analysis. The linguistic analysis was conducted using selected analytical tools from the systemic functional linguistics framework. A diversity of linguistic resources and meanings were identified from the students' explanations, which reveal the extent to which the students were able to employ linguistic resources to construct written scientific explanations and the challenges involved. Both content and linguistic analyses also illuminate patterns of language use that are significant for realising scientific meanings. Finally, a comparison is made in the use of linguistic resources between the students' explanations and the instructional language to highlight possible links. This comparison reveals that the teachers' expectations of the students' written explanations were seldom reflected in their oral questioning or made explicit during the instruction. The findings of this study suggest that a focus on conceptual development is not sufficient in itself to foster students' ability to construct explanations. Pedagogical implications involving the support needed by primary students to construct scientific explanations are discussed.

    Full Text Available Purpose: We propose and apply a simplified nowcasting model to understand the correlations between social attention and topic trends of scientific publications. Design/methodology/approach: First, topics are generated from the obesity corpus by using the latent Dirichlet allocation (LDA algorithm and time series of keyword search trends in Google Trends are obtained. We then establish the structural time series model using data from January 2004 to December 2012, and evaluate the model using data from January 2013. We employ a state-space model to separate different non-regression components in an observational time series (i.e. the tendency and the seasonality and apply the “spike and slab prior” and stepwise regression to analyze the correlations between the regression component and the social media attention. The two parts are combined using Markov-chain Monte Carlo sampling techniques to obtain our results. Findings: The results of our study show that (1 the number of publications on child obesity increases at a lower rate than that of diabetes publications; (2 the number of publication on a given topic may exhibit a relationship with the season or time of year; and (3 there exists a correlation between the number of publications on a given topic and its social media attention, i.e. the search frequency related to that topic as identified by Google Trends. We found that our model is also able to predict the number of publications related to a given topic. Research limitations: First, we study a correlation rather than causality between topics' trends and social media. As a result, the relationships might not be robust, so we cannot predict the future in the long run. Second, we cannot identify the reasons or conditions that are driving obesity topics to present such tendencies and seasonal patterns, so we might need to do “field” study in the future. Third, we need to improve the efficiency of our model by finding more efficient

  19. Towards Building Science Teachers’ Understandings of Contemporary Science Practices

    Directory of Open Access Journals (Sweden)

    Greg Lancaster

    2017-03-01

    Full Text Available Faculties of Education and Science at Monash University have designed a Masters unit to assist pre-service and in-service science teachers in exploring the practices of contemporary science and examine how varied understandings can influence science communication. Teachers are encouraged to explore their current understandings of the Nature of Science (NoS and to contrast their views with those known to be widely held by society (Cobern & Loving, 1998. Teachers are challenged to provide insights into their thinking relating to the NoS. In order to build understandings of contemporary science practice each teacher shadows a research scientist and engages them in conversations intended to explore the scientists’ views of NoS and practice. Findings suggest that teachers were initially uncomfortable with the challenge to express ideas relating to their NoS and were also surprised how diverse the views of NoS can be among teachers, scientists and their peers, and that these views can directly impact ways of communicating contemporary science practice.

  20. Reflective Practice: Eight Stages of Publishing a Scientific Research Paper

    Directory of Open Access Journals (Sweden)

    Stephen K. Donovan

    2018-03-01

    Full Text Available This paper suggests a methodology of academic paper classification for the scientist intending to contribute to peer-reviewed scientific literature. This will enable the progress of the typescript through the publication system to be accurately determined at any stage. The publication process is split into eight subdivisions of differing worth and import: in navel contemplation; in preparation; submitted; in review; revision, revised, and resubmitted; accepted; in press; and publication. Papers in navel contemplation are referred to as in preparation by many, which can be an embarrassment when asked exactly what has been prepared. Rather than listing papers as in preparation in academic submissions, it is better to list them as unpublished data until published. Efficient authors keep a close watch on their papers between submission and the proof stage. They must be sufficiently organized to manage their publications and to be aware when things slow down. The methodology is flexible and, if it does not work for some authors, then they have a simple framework to adapt to their own preferences. In short, scientists need to show care and not be overly optimistic about the progress of any paper.

    The Third Tibetan Plateau atmospheric scientific experiment (TIPEX-III) was initiated jointly by the China Meteorological Administration, the National Natural Scientific Foundation, and the Chinese Academy of Sciences. This paper presents the background, scientific objectives, and overall experimental design of TIPEX-III. It was designed to conduct an integrated observation of the earth-atmosphere coupled system over the Tibetan Plateau (TP) from land surface, planetary boundary layer (PBL), troposphere, and stratosphere for eight to ten years by coordinating ground- and air-based measurement facilities for understanding spatial heterogeneities of complex land-air interactions, cloud-precipitation physical processes, and interactions between troposphere and stratosphere. TIPEX-III originally began in 2014, and is ongoing. It established multiscale land-surface and PBL observation networks over the TP and a tropospheric meteorological radiosonde network over the western TP, and executed an integrated observation mission for cloud-precipitation physical features using ground-based radar systems and aircraft campaigns and an observation task for atmospheric ozone, aerosol, and water vapor. The archive, management, and share policy of the observation data are also introduced herein. Some TIPEX-III data have been preliminarily applied to analyze the features of surface sensible and latent heat fluxes, cloud-precipitation physical processes, and atmospheric water vapor and ozone over the TP, and to improve the local precipitation forecast. Furthermore, TIPEX-III intends to promote greater scientific and technological cooperation with international research communities and broader organizations. Scientists working internationally are invited to participate in the field campaigns and to use the TIPEX-III data for their own research.

    2016-07-01

    Captain Charles Moore introduced the world to the "Great Pacific Garbage Patch" in the mid-1990s, and images of plastic debris in the oceans began to sweep the media. Since then, there has been increasing interest from scientists, the public, and policy makers regarding plastic debris in the environment. Today, there remains no doubt that plastic debris contaminates aquatic (marine and freshwater) habitats and animals globally. The growing scientific evidence demonstrates widespread contamination from plastic debris, and researchers are beginning to understand the sources, fate, and effects of the material. As new scientific understanding breeds new questions, scientists are working to fill data gaps regarding the fate and effects of plastic debris and the mechanisms that drive these processes. In parallel, policy makers are working to mitigate this contamination. The authors focus on what is known about plastic debris that is relevant to policy by reviewing some of the weight of evidence regarding contamination, fate, and effects of the material. Moreover, they highlight some examples of how science has already been used to inform policy change and mitigation and discuss opportunities for future linkages between science and policy to continue the relationship and contribute to effective solutions for plastic debris.

    In the new curriculum, questioning is one of theaspects of scientific approach learning. It means teachers should facilitate students to ask their questions during science learning. The purpose of this research was to reveal the prospective science teachers’ understanding about questioning and how the science teachers implement of that in the scientific approach learning. Data of the prospective science teachers’ understanding was explored from their teaching plan that produced during microteaching. The microteaching is an activity that should be followed by students before they conduct partnership program in school. Data about theimplementation of questioning that conducted by theteacher was be collected by video-assisted observation in junior school science class. The results showed that majority of the prospective science teachers had difficulty to write down in their teaching plan about how to facilitate students to ask their questions, even majority of them understood that questioning is not students’ activity, but it is an activity that should be done by teachers. Based on the observation showed that majority of teachers did not yet implement a learning that facilitates students to ask their questions.

  4. Modeling as an Anchoring Scientific Practice for Explaining Friction Phenomena

    Neilson, Drew; Campbell, Todd

    2017-12-01

    Through examining the day-to-day work of scientists, researchers in science studies have revealed how models are a central sense-making practice of scientists as they construct and critique explanations about how the universe works. Additionally, they allow predictions to be made using the tenets of the model. Given this, alongside research suggesting that engaging students in developing and using models can have a positive effect on learning in science classrooms, the recent national standards documents in science education have identified developing and using models as an important practice students should engage in as they apply and refine their ideas with peers and teachers in explaining phenomena or solving problems in classrooms. This article details how students can be engaged in developing and using models to help them make sense of friction phenomena in a high school conceptual physics classroom in ways that align with visions for teaching and learning outlined in the Next Generation Science Standards. This particular unit has been refined over several years to build on what was initially an inquiry-based unit we have described previously. In this latest iteration of the friction unit, students developed and refined models through engaging in small group and whole class discussions and investigations.

  5. The importance of professional skills alongside scientific and technical excellence to underpin ethical geoscience practice

    Allington, Ruth; Fernandez-Fuentes, Isabel

    2013-04-01

    There is consensus that reliable ground models, based on a sound understanding of the geology and surface processes are vital as a basis for natural hazard identification and risk assessment, and there is a great deal of skill and experience in the geoscience community with mapping, modelling and predicting natural hazards and their likely impacts. This presentation will highlight the contributions of geology and geomorphology in the identification of natural hazards and mitigation of their impacts. It will then consider a range of "professional skills" that are needed by geoscientists working with other specialists and non-specialists (e.g. engineers, emergency services, land-use planners, architects responsible for building codes, politicians, regulators, the public etc) alongside technical and scientific excellence. It will argue that development and application of both scientific/technical and professional skills is essential to ensure that the maps, models and other data relevant to natural hazards and environmental change are used to provide effective public protection through communication, land-use planning and planning for resilience. The professional skills of particular importance include interdisciplinary collaboration; project management; cost-benefit analysis; effective communication with specialists and non specialists (especially the public); and facilitative skills. All the technical, scientific and professional skills need to be applied competently and with the highest standards of ethical underpinning. The contribution will consider how this can be achieved (or at least facilitated) through professional training, award of professional titles, licensure etc, drawing on international examples of best practice in professional codes of conduct and regulation directed to the protection of the public.

    Beggrow, Elizabeth P.; Ha, Minsu; Nehm, Ross H.; Pearl, Dennis; Boone, William J.

    2013-07-01

    The landscape of science education is being transformed by the new Framework for Science Education (National Research Council, A framework for K-12 science education: practices, crosscutting concepts, and core ideas. The National Academies Press, Washington, DC, 2012), which emphasizes the centrality of scientific practices—such as explanation, argumentation, and communication—in science teaching, learning, and assessment. A major challenge facing the field of science education is developing assessment tools that are capable of validly and efficiently evaluating these practices. Our study examined the efficacy of a free, open-source machine-learning tool for evaluating the quality of students' written explanations of the causes of evolutionary change relative to three other approaches: (1) human-scored written explanations, (2) a multiple-choice test, and (3) clinical oral interviews. A large sample of undergraduates (n = 104) exposed to varying amounts of evolution content completed all three assessments: a clinical oral interview, a written open-response assessment, and a multiple-choice test. Rasch analysis was used to compute linear person measures and linear item measures on a single logit scale. We found that the multiple-choice test displayed poor person and item fit (mean square outfit >1.3), while both oral interview measures and computer-generated written response measures exhibited acceptable fit (average mean square outfit for interview: person 0.97, item 0.97; computer: person 1.03, item 1.06). Multiple-choice test measures were more weakly associated with interview measures (r = 0.35) than the computer-scored explanation measures (r = 0.63). Overall, Rasch analysis indicated that computer-scored written explanation measures (1) have the strongest correspondence to oral interview measures; (2) are capable of capturing students' normative scientific and naive ideas as accurately as human-scored explanations, and (3) more validly detect understanding

  8. Training transfer: scientific background and insights for practical application.

    Issurin, Vladimir B

    2013-08-01

    Training transfer as an enduring, multilateral, and practically important problem encompasses a large body of research findings and experience, which characterize the process by which improving performance in certain exercises/tasks can affect the performance in alternative exercises or motor tasks. This problem is of paramount importance for the theory of training and for all aspects of its application in practice. Ultimately, training transfer determines how useful or useless each given exercise is for the targeted athletic performance. The methodological background of training transfer encompasses basic concepts related to transfer modality, i.e., positive, neutral, and negative; the generalization of training responses and their persistence over time; factors affecting training transfer such as personality, motivation, social environment, etc. Training transfer in sport is clearly differentiated with regard to the enhancement of motor skills and the development of motor abilities. The studies of bilateral skill transfer have shown cross-transfer effects following one-limb training associated with neural adaptations at cortical, subcortical, spinal, and segmental levels. Implementation of advanced sport technologies such as motor imagery, biofeedback, and exercising in artificial environments can facilitate and reinforce training transfer from appropriate motor tasks to targeted athletic performance. Training transfer of motor abilities has been studied with regard to contralateral effects following one limb training, cross-transfer induced by arm or leg training, the impact of strength/power training on the preparedness of endurance athletes, and the impact of endurance workloads on strength/power performance. The extensive research findings characterizing the interactions of these workloads have shown positive transfer, or its absence, depending on whether the combinations conform to sport-specific demands and physiological adaptations. Finally, cross

    2017-12-01

    Earthquake scientists are without doubt experts in understanding earthquake probabilities, magnitudes, and intensities, as well as the potential consequences of them to community infrastructures and inhabitants. One critical challenge these scientific experts face, however, rests with communicating what they know to the people they want to help. Helping scientists translate scientific information to non-scientists is something Drs. Tim and Deanna Sellnow have been committed to for decades. As such, they have compiled a host of data-driven best practices for communicating effectively to non-scientific publics about earthquake forecasting, probabilities, and warnings. In this session, they will summarize what they have learned as it may help earthquake scientists, emergency managers, and other key spokespersons share these important messages to disparate publics in ways that result in positive outcomes, the most important of which is saving lives.

  10. Nurse ethical awareness: Understanding the nature of everyday practice.

    Much attention has been paid to the role of the nurse in recognizing and addressing ethical dilemmas. There has been less emphasis, however, on the issue of whether or not nurses understand the ethical nature of everyday practice. Awareness of the inherently ethical nature of practice is a component of nurse ethical sensitivity, which has been identified as a component of ethical decision-making. Ethical sensitivity is generally accepted as a necessary precursor to moral agency, in that recognition of the ethical content of practice is necessary before consistent action on behalf of patient interests can take place. This awareness is also compulsory in ensuring patient good by recognizing the unique interests and wishes of individuals, in line with an ethic of care. Scholarly and research literature are used to argue that bolstering ethical awareness and ensuring that nurses understand the ethical nature of the role are an obligation of the profession. Based on this line of reasoning, recommendations for education and practice, along with directions for future research, are suggested.

  13. A Framework for Understanding Physics Students' Computational Modeling Practices

    Science.gov (United States)

    Lunk, Brandon Robert

    With the growing push to include computational modeling in the physics classroom, we are faced with the need to better understand students' computational modeling practices. While existing research on programming comprehension explores how novices and experts generate programming algorithms, little of this discusses how domain content knowledge, and physics knowledge in particular, can influence students' programming practices. In an effort to better understand this issue, I have developed a framework for modeling these practices based on a resource stance towards student knowledge. A resource framework models knowledge as the activation of vast networks of elements called "resources." Much like neurons in the brain, resources that become active can trigger cascading events of activation throughout the broader network. This model emphasizes the connectivity between knowledge elements and provides a description of students' knowledge base. Together with resources resources, the concepts of "epistemic games" and "frames" provide a means for addressing the interaction between content knowledge and practices. Although this framework has generally been limited to describing conceptual and mathematical understanding, it also provides a means for addressing students' programming practices. In this dissertation, I will demonstrate this facet of a resource framework as well as fill in an important missing piece: a set of epistemic games that can describe students' computational modeling strategies. The development of this theoretical framework emerged from the analysis of video data of students generating computational models during the laboratory component of a Matter & Interactions: Modern Mechanics course. Student participants across two semesters were recorded as they worked in groups to fix pre-written computational models that were initially missing key lines of code. Analysis of this video data showed that the students' programming practices were highly influenced by

  14. Using Next Generation Science Standards (NGSS) Practices to Address Scientific Misunderstandings Around Complex Environmental Issues

    The new NGSS provide an important opportunity for scientists to develop curriculum that links the practice of science to research-based data in order to improve understanding in areas of science that are both complex and confusing. Our curriculum focuses in particular on the fate and transport of anthropogenic radionuclides. Radioactivity, both naturally occurring and anthropogenic, is highly debated and largely misunderstood, and for large sections of the population is a source of scientific misunderstanding. Developed as part of the international GEOTRACES project which focuses on identifying ocean processes and quantifying fluxes that control the distributions of selected trace elements and isotopes in the ocean, and on establishing the sensitivity of these distributions to changing environmental conditions, the curriculum topic fits nicely into the applied focus of NGSS with both environmental and topical relevance. Our curriculum design focuses on small group discussion driven by questions, yet unlike more traditional curriculum pieces these are not questions posed to the students, rather they are questions posed by the students to facilitate their deeper understanding. Our curriculum design challenges the traditional question/answer memorization approach to instruction as we strive to develop an educational approach that supports the practice of science as well as the NGSS Cross Cutting Concepts and the Science & Engineering Practices. Our goal is for students to develop a methodology they can employ when faced with a complex scientific issue. Through background readings and team discussions they identify what type of information is important for them to know and where to find a reliable source for that information. Framing their discovery around key questions such as "What type of radioactive decay are we dealing with?", "What is the potential half-life of the isotope?", and "What are the pathways of transport of radioactivity?" allows students to evaluate a

    2017-02-01

    This study examined the extent to which the instructional practices of science teachers in Barbados are congruent with best practices for teaching for scientific literacy. Additionally, through observation of practice, it sought to determine the teachers' demonstrated role in the classroom, their demonstration of learning through discourse, learning goals and the nature of classroom activities. Five hundred nineteen students from 12 of the 23 secondary schools on the island and 15 teachers across 8 schools participated in the study. Data were collected by means of a questionnaire, an observational schedule and field notes. It was found that while problem-solving and questioning were mainly used in the classroom, the use of experiments was among the least popular teaching strategies. Additionally, results showed that teachers' display of the knowledge of the characteristics of scientific literacy was unsatisfactory. Generally, the findings indicate a gap between teaching for scientific literacy as expressed in the literature and current instructional practices in secondary science classrooms in Barbados.

    Widespread enthusiasm for establishing scientific codes of conduct notwithstanding, the utility of such codes in influencing scientific practice is not self-evident. It largely depends on the implementation phase following their establishment--a phase which often receives little attention. The aim of this paper is to provide recommendations for guiding effective implementation through an assessment of one particular code of conduct in one particular institute. Based on a series of interviews held with researchers at the Department of Biotechnology of Delft University of Technology, this paper evaluates how the Netherlands Code of Conduct for Scientific Practice is received by those it is supposed to govern. While respondents agreed that discussion of the guiding principles of scientific conduct is called for, they did not consider the code as such to be a useful instrument. As a tool for the individual scientific practitioner, the code leaves a number of important questions unanswered in relation to visibility, enforcement, integration with daily practice and the distribution of responsibility. Recommendations are provided on the basis of these questions. There is more at stake than merely holding scientific practitioners to a proper exercise of their duties; implementation of scientific society codes of conduct also concerns the further motives and value commitments that gave rise to their establishment in the first place.

    (Abstract only) Social learning theory suggests that students who wish to become scientists will benefit by being active researchers early in their educational careers. As coauthors of published research, they identify themselves as scientists. This provides them with the inspiration, motivation, and staying power that many will need to complete the long educational process. This hypothesis was put to the test over the past decade by a one-semester astronomy research seminar where teams of students managed their own research. Well over a hundred published papers coauthored by high school and undergraduate students at a handful of schools substantiated this hypothesis. However, one could argue that this was a special case. Astronomy, after all, is supported by a large professional-amateur community-of-practice. Furthermore, the specific area of research - double star astrometry - was chosen because the observations could be quickly made, the data reduction and analysis was straight forward, and publication of the research was welcomed by the Journal of Double Star Observations. A recently initiated seminar development and expansion program - supported in part by the National Science Foundation - is testing a more general hypothesis that: (1) the seminar can be successfully adopted by many other schools; (2) research within astronomy can be extended from double star astrometry to time series photometry of variable stars, exoplanet transits, and asteroids; and (3) the seminar model can be extended to a science beyond astronomy: environmental science' specifically atmospheric science. If the more general hypothesis is also supported, seminars that similarly feature published high school and undergraduate student team research could have the potential to significantly improve science education by increasing the percentage of students who complete the education required to become professional scientists.

  2. On Scientific Status and Practical Significance of One Psychological Theory

    Full Text Available Since the late 1950s, a significant number of authors tried to use Galperin’s approach (which is well-known as the “Theory of planned stage-by-stage formation of mental actions”, or the PSFMA Theory to improve schooling processes and results. Looking back at the more than fifty-year history of Galperin’s approach, one may note that the 1960s and the early 1970s were the periods of the great optimism concerning effectiveness and efficiency of its practical application. It seemed possible to transform radically the way and the traditional results of learning/teaching process. To compare the 60s-70s and the 80s-90s publications one could easily discover a significant decrease of a wave of optimism concerning the PSFMA’s application. Besides the obvious social-economic and social-psychological reasons there exists a methodological reason concerning the ways and means of the Galperin’s approach use. Historically, the substantial pedagogical results of planned stage-by-stage formation of mental actions first came to the fore. However, the proponents’ enthusiasm about really unusual and hopeful results had a reverse side: it led to the serious misunderstanding of the status of Galperin’s approach and transformed the last to some absolute knowledge like a sort of “philosophers’ stone”. The successful application of the statements of PSFMA does not mean a literal reproduction of some abstract general procedure, but a creative design of a system of necessary and sufficient psychological conditions adapted to a concrete schooling situation. The elaboration of such a procedure occupies an intermediate position between the fundamental psychological knowledge and the real process of schooling. The three-model system is considered to bridge a gap between the fundamental knowledge introduced by Galperin and the real circumstances of learning/teaching situation.

    Full Text Available Students are engaged and improve their critical thinking skills in laboratory courses when they have the opportunity to design and conduct inquiry-based experiments that generate novel results. A discovery-driven project for a microbiology, genetics, or multidisciplinary research laboratory course was developed to familiarize students with the scientific method. In this multi-lab module, students determine whether their chosen stress conditions induce conjugation and/or cell death of the model BSL-1 Gram-positive bacterium Bacillus subtilis. Through consultation of the primary literature, students identify conditions or chemicals that can elicit DNA damage, the SOS response, and/or cellular stress.  In groups, students discuss their selected conditions, develop their hypotheses and experimental plans, and formulate their positive and negative controls. Students then subject the B. subtilis donor cells to the stress conditions, mix donors with recipients to allow mating, and plate serial dilutions of the mixtures on selective plates to measure how the treatments affect conjugation frequency and donor cell viability.  Finally, students analyze and discuss their collective data in light of their controls. The goals of this module are to encourage students to be actively involved in the scientific process while contributing to our understanding of the conditions that stimulate horizontal gene transfer in bacteria.

    2018-03-01

    Drawn from the cultural-historical theories of knowing and doing science, this article uses the concept of professional vision to explore what scientists and experienced teachers see and articulate as important aspects of climate science practices. The study takes an abductive reasoning approach to analyze scientists' videotaped lectures to recognize what scientists pay attention to in their explanations of climate science practices. It then analyzes how ideas scientists attended align with experienced teachers' sense-making of scientific practices to teach climate change. The findings show that experienced teachers' and scientists' explanations showed alignment in the focus on scientific practices, but indicated variations in the temporal and spatial reasoning of climate data. Furthermore, the interdisciplinarity of climate science was emphasized in climate scientists' lectures, but was not apparent once scientists and teachers shared the same culture in meetings to provide feedback to preservice teachers. Given the importance of teaching through scientific practices in classrooms, this study provides suggestions to capture the epistemic diversity of scientific disciplines.

    A successful landslide risk reduction program requires that the society is aware and understand the landslide problems within the geographic area involved. Central organizations that manage national landslide risks should: a) create and systematically applied natural hazard laws/national landslide strategies, where roles and limits of responsibilities of federal, state, provincial, municipal and private entities are well defined; c) establish fruitful multidisciplinary and interinstitutional collaboration among scientists; d) provide good risk assessments in which landslide experts report transparently what is really known and the limitations of methods and tools used; e) share and systematically communicate their knowledge more effectively with all private and public stakeholders involved, paying attention to providing balanced information about risks and addressing inevitable uncertainties; f) support the mass-media in spreading correct scientific information; g) perform serious risk and cost-benefit analyses before mitigation measures are realized; h) assist local authorities in the application of land-use planning policies and g) built trust and confidence by means of a continuous contact and communication with the public and local authorities. However, this is not yet achieved, not even in developed countries where, in theory, more economical resources are available and people are better educated then in developing countries. Herein I make some observations on how national landslide prevention efforts are being organized in two countries (Nicaragua and Norway), where I have been worked at governmental agencies as landslide expert in the last 10 years. I start describing similarities and differences between the countries and try to compare practices and experiences. The analysis was motivated by the following questions: Why after so many years of landslide mapping and investigations, landslide prevention is not good and effective as it should be? Is this

    The APS bridge program works to improve the participation of students from traditionally under-represented groups in graduate physics. Related to this, we have undertaken research to improve our understanding of graduate admissions practices from the point of view of both students and faculty. Previously, we collected data on admission practices from over 75% of PhD-granting physics departments in the U.S., which highlighted the role of various criteria (including the GRE) in the admissions decisions faculty make, and identified the efforts (or lack thereof) made to recruit students from traditionally under-represented backgrounds. Currently, we are conducting a parallel study of upper division undergraduate physics majors to investigate their post-graduation career intentions, their perceptions of graduate admissions and perceived barriers to admissions, and to understand how undergraduate experiences influence students' career interests. Lastly, we are also studying, in depth, students who have been connected to physics bridge programs, to understand post-admission experiences and the enculturation process in physics departments. In this talk, we report on the collective results of these research efforts to date. NSF Award # 1143070.

  10. Understanding students' practical epistemologies and their influence on learning through inquiry

    Sandoval, William A.

    2005-07-01

    It has long been a goal of science education in the United States that students leave school with a robust understanding of the nature of science. Decades of research show that this does not happen. Inquiry-based instruction is advocated as a means for developing such understanding, although there is scant direct evidence that it does. There is a gap between what is known about students' inquiry practices and their epistemological beliefs about science. Studies of students' ideas about epistemological aspects of formal science are unlikely to shed any light on how they perceive their own inquiry efforts. Conversely, inquiry-based instruction that does not account for the epistemological beliefs that guide students' inquiry stands very little chance of helping students to understand professional science. This paper reviews largely independent lines of research into students' beliefs about the nature of science and their practices of inquiry to argue that students' inquiry is guided by practical epistemologies that are in need of study. An approach to studying practical epistemologies is proposed that has the potential to produce a better psychological theory of epistemological development, as well as to realize goals of a science education that develops scientifically informed citizens.

  11. Understanding partnership practice in child and family nursing through the concept of practice architectures.

    2013-09-01

    A significant international development agenda in the practice of nurses supporting families with young children focuses on establishing partnerships between professionals and service users. Qualitative data were generated through interviews and focus groups with 22 nurses from three child and family health service organisations, two in Australia and one in New Zealand. The aim was to explore what is needed in order to sustain partnership in practice, and to investigate how the concept of practice architectures can help understand attempts to enhance partnerships between nurses and families. Implementation of the Family Partnership Model (FPM) is taken as a specific point of reference. Analysis highlights a number of tensions between the goals of FPM and practice architectures relating to opportunities for ongoing learning; the role of individual nurses in shaping the practice; relationships with peers and managers; organisational features; and extra-organisational factors. The concept of practice architectures shows how changing practice requires more than developing individual knowledge and skills, and avoids treating individuals and context separately. The value of this framework for understanding change with reference to context rather than just individual's knowledge and skills is demonstrated, particularly with respect to approaches to practice development focused on providing additional training to nurses. © 2012 John Wiley & Sons Ltd.

  13. Understanding beginning teacher induction: A contextualized examination of best practice

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available The problems that teachers face early in their careers are a major factor in growing rates of attrition among neophyte teachers. According to the Organisation for Economic Co-operation and Development, high rates of attrition, coupled with and aging teacher population in many countries in the developed world, may cause a teacher shortage crisis in coming years. Beginning teacher induction is an imperative process in acculturating teachers to their new careers and helping them overcome the hardships of teaching and the accreditation process. While induction practices have become more common in recent years, there are still no mandated structures for inducting teachers into the profession throughout Australia. This article reviews a number of international induction programs, which have been successful in supporting beginning teachers and curbing attrition rates, to emphasize why many programs are inadequate at meeting the needs of beginning teachers. The review proposes a definition for induction to better understand common misconceptions and highlights best practice induction as a way to retain quality teachers in the profession and help ameliorate conditions for beginning teachers. Finally, recommendations are made, specifically in the Australian context, which could help to improve induction practices to better acculturate neophyte teachers to their profession.

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

    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.

  19. Preservice special education teachers' understandings, enactments, views, and plans for scientific inquiry: Issues and hopes

    Science.gov (United States)

    Ghosh, Rajlakshmi

    This study examined the understandings, enactments, views, and plans for scientific inquiry held by preservice special education teachers enrolled in a K--8 general science methods course. Sixteen participants from four special education concentration areas---Mild to Moderate Educational Needs, Moderate to Intense Educational Needs, Mild to Moderate Educational Needs with Language Arts and Reading Emphasis, and Early Childhood Intervention---participated in this study. Qualitative data were collected from questionnaires, interviews, teaching videos, lesson plans, planning commentaries, and reflection papers. Data were analyzed using a grounded theory approach (Strauss & Corbin, 1990) and compared against the theoretical view of inquiry as conceptualized by the National Research Council (NRC, 2000). The participants held unique interpretations of inquiry that only partially matched with the theoretical insights provided by the NRC. The participants' previous science learning experiences and experiences in special education played an important role in shaping their conceptualizations of inquiry as learned in the science methods class. The impacts of such unique interpretations are discussed with reference to both science education and special education, and implications for teacher education are provided.

    Traditional Chinese Medicine (TCM) serves as the most common alternative therapeutic approach for Western medicine and benefits IBS patients globally. Due to the lack of scientific evidence in the past, TCM formulas were not internationally well recognized as promising IBS remedies. In this review, firstly, we present the etiology and therapy of IBS in terms of traditional Chinese medical theory. Secondly, we summarize the clinical randomized controlled trials (RCTs) of TCM formulas for IBS patients that are available in the literature (from 1998 to September 2013), in which 14 RCTs conducted of high quality were discussed in detail. Of the 14 selected trials, 12 of those concluded that TCM formulas provided superior improvement in the global symptoms of IBS patients over the placebo or conventional medicines. As well, all 14 RCTs suggested that TCM formulas have good safety and tolerability. Last but not least, we explore the pharmacological mechanisms of the anti-IBS TCM formulas available in the literature (from 1994 to September, 2013). Collectively, in combating IBS symptoms, most TCM formulas exert multi-targeting actions including the regulation of neurotransmitters and hormones in the enteric nervous system (ENS), modulation of smooth muscle motility in the gastrointestinal (GI) tract, modulation of the hypothalamic-pituitary-adrenal (HPA) axis, attenuation of intestinal inflammation and restoration of intestinal flora, etc. In conclusion, TCM formulas appear to be promising for IBS treatment. This review provides a useful reference for the public in furthering a better understanding and acceptance of TCM formulas as IBS remedies.

    To explore the nature of collaboration between registered nurses and general practitioners in Australian general practice. There is international recognition that collaboration between health professionals can improve care coordination, enhance health outcomes, optimise the work environment and reduce healthcare costs. However, effective collaboration requires a clear understanding of each team member's role. A qualitative approach guided by Naturalistic Inquiry was used to elicit and interpret participant narratives. Eight general practitioners and fourteen registered nurses working in general practice were purposefully recruited. Data were collected via individual, semi-structured face-to-face interviews during February to May 2015. Interviews were audio recorded and transcribed verbatim. Data were analysed using thematic analysis. Data revealed three overarching themes. This study presents the data for the overarching theme 'Understanding the general practice registered nurse's role'. Many general practitioner participants lacked clarity around the role and scope of practice of the registered nurse. At the same time, nursing participants often articulated their role as an assistant rather than as an independent health professional. This limited collaboration and the nurses' role within the team. Collaboration was enhanced when general practitioners actively sought an understanding of the registered nurses scope of practice. Clarifying the nurses' role promotes collaboration and supports nurses to work to the full extent of their practice. This is important in terms of optimising the nurses' role within the team and reinforcing their professional identity. Identification of key issues around understanding the nurses' role may help inform strategies that improve collaboration and workplace relations. © 2016 John Wiley & Sons Ltd.

  4. An exploration of middle school science teachers' understandings and teaching practice of science as inquiry

    Castle, Margaret Ann

    understanding of science increases (Akkus, Gunel & Hand, 2007; Gibson, 2002; Liu, Lee & Linn, 2010). As a result, it is important to explore middle school science teachers' definition of science as inquiry because of its importance in how their understandings are reflected in their practice. Researchers must witness, first- hand, what is taking place in middle school science classrooms with respect to the teaching of scientific inquiry before recommendations for improvements can be made. We must also allow opportunities for middle school science teachers to broach, examine, explore, interpret and report implementation strategies when practicing the elements of scientific inquiry as a science content area. It then stands to reason that more research needs to be done to: (1) assess teachers' knowledge related to reform-based teaching, (2) investigate teachers' views about the goals and purposes of inquiry, and (3) investigate the processes by which teachers carry out SI and motivation for undertaking such a complex and difficult to manage form of instruction. The purpose of this study was to examine middle school science teachers' understandings and skills related to scientific inquiry; how those understandings and skills were translated into classroom practice, and the role the school district played in the development of such understandings and skills.

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

    Allison, Elizabeth Rowland

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

  6. Novice and experienced science teachers' understanding and uses of practical activities

    Science.gov (United States)

    Landolfi, Emilio

    While practical work has a long and valued tradition in school science programmes, its usefulness and validity of the claims for its value have occasionally come under attack. Nonetheless, school science laboratory activities have managed to remain part of the science curriculum in most schools for the better part of a century. The experiences they can provide students are often highly regarded by teachers, for the following reasons: "to motivate students by stimulating interest and enjoyment, to teach laboratory skills, to enhance the learning of scientific knowledge, to give insight into scientific method and to develop expertise in using it, and to develop certain 'scientific attitudes', such as open-mindedness, objectivity and willingness to suspend judgment" (Hodson, 1993b: 90). This investigation is directed at examining differences in understanding and use(s) of practical activities by one experienced grade 11/OAC (senior) and two novice grade 7/8 (intermediate) science teachers. Through the use of classroom observations, as well as teacher and student interviews, teacher questionnaires, and students' work, three separate case studies were conducted into: teachers' overall use(s) of lab work, teachers' views on the nature of science, teachers' sources of knowledge used (in addition to their knowledge of subject matter), and teachers' responses to practical activities not going as planned during lessons. While novice and experienced science educators at the intermediate and senior levels both use practical activities in their teaching, this study aims to explore how lab work is deployed differently by these two different groups of teachers (novice vs. experienced) within these two educational settings (i.e. the grade 7/8 vs. grade 11/OAC science lab/classroom). A sixteen week 'case study' was conducted---eight weeks with two grade 7/8 relatively inexperienced science teachers and eight weeks with one grade 11/OAC more experienced science teacher---for the

  9. Building Capacity for Evidence-Based Practice: Understanding How Licensed Practical Nurses (LPNs) Source Knowledge.

    Science.gov (United States)

    Phillips, Leah; Neumeier, Melanie

    2018-03-23

    In Canada, all nurses are required to engage in evidence-based practice (EBP) as an entry-to-practice competency; however, there is little research that examines Licensed Practical Nurses' (LPNs') information seeking behaviors or preferred sources of knowledge to conduct EBP. Due to the differences in education and roles of LPNs and Registered Nurses (RNs), it is both necessary and important to gain an understanding of how LPNs utilize evidence in their unique nursing practice. The purpose of this study was to investigate how LPNs source knowledge for their nursing practice. A descriptive, cross-sectional survey of LPNs from Alberta, Canada asked participants to rank sources of knowledge that inform their practice. Responses were correlated with age and years of practice. Analysis of variance was used to determine if there were significant mean differences between average scores and place of employment. LPN participants used similar sources of knowledge as RNs. The top source of knowledge for both RNs and LPNs was the information they learn about each individual client and the least utilized sources of knowledge were articles published in nursing, medical, and research journals, tradition, and popular media. This finding is consistent with previous studies on RNs that found nurses do not often access current research evidence to inform their practice. Since relatively few LPNs access nursing and research journals, it is important to tailor EBP education information to the workplace context. Future avenues of research might explore the potential of using in-services and webinars to disseminate information and skills training on EBP to the LPNs, as this was a popular source of practice knowledge. © 2018 The Authors.

    The Murray-Darling Basin incorporates Australia's three longest rivers and is important for an agricultural industry worth more than $9 billion per annum, a rich biodiversity of habitat and species, and the very life of its traditional owners. The complex and sometimes enigmatic relationships between modes of variability and Australian regional rainfall distribution means that reliable projections of future water availability remain highly uncertain. Persistent drought, with associated heat stress and high fire danger, and episodic flooding rains present further challenges. Indeed, recent extremes likely herald a tipping point for the communities and ecosystems that rely on the river system. The Barmah-Millewa region in the Murray-Darling Basin is the heart of Yorta Yorta Traditional Tribal Lands. The Yorta Yorta continue to assert their inherent rights to country and have shown through oral, documentary and material evidence, that their social, spiritual, economic and cultural links with country have never been broken. Current water policy and practice, highly contested community consultation processes, cross-border governance issues and a changing social landscape create in this region a microcosm for understanding the complex demands of economic, environmental and cultural security along the Murray-Darling Basin as the climate changes. New approaches to bridging the gap between scientific and Indigenous epistemologies have emerged in recent years, including for example ecosystem-based adaptation (Vignola et al. 2009) and the analysis of cultural water flows (Weir 2010). The potential for innovation using these approaches has informed a study that investigates how the deep knowledge of country of the Yorta Yorta people can be combined with state of the art climate science to develop a better understanding of the competing demands on water resources in the Barmah-Millewa region now and in the future. An important dimension of this collaborative work with the Yorta

  11. Introduction to four papers on Curt Richter and analysis of his scientific practice.

    Smith, Gerard P

    2007-09-01

    Curt Richter was one of the founders of our field. He did outstanding research for over 60 years. Richter did fundamental work in appetite for food and minerals in the 1930s and discovered the homeostatic functions of ingestive behavior. This paper introduces four papers on specific topics of his work by contemporaneous experts. Each of the papers reviews Richter's experiments and then shows how the problem developed since he left it. The papers demonstrate that providing the historical basis for contemporary science is not only instructive, it is also heuristic for the science waiting to be done. In addition to introducing the four papers, I analyze the scientific ideas, values, and men that influenced Richter's scientific practice. I conclude that Claude Bernard, Walter Cannon, Francois Magendie, and Maurice Arthus were important for Richter's scientific ideas and values, but it was the joy of research that explains his experimental success for over 60 years.

    Mathematical models and mathematical modeling play different roles in the different areas and problems in which they are used. The function and status of mathematical modeling and models in the different areas depend on the scientific practice as well as the underlying philosophical and theoretical...... position held by the modeler(s) and the practitioners in the extra-mathematical domain. For students to experience the significance of different scientific practices and cultures for the function and status of mathematical modeling in other sciences, students need to be placed in didactical situations...... where such differences are exposed and made into explicit objects of their reflections. It can be difficult to create such situations in the teaching of contemporary science in which modeling is part of the culture.

    Recupero, Patricia R

    2008-01-01

    It is important for forensic experts to understand how clinical practice guidelines may enter the courtroom, what role they may play in a trial, and how they relate to expert testimony. Guidelines enter the record in several different ways and in several types of cases, typically with the assistance of an expert witness. A common vehicle for their introduction is the learned-treatise exception to the hearsay rule. Case law before and after Daubert v. Merrell Dow Pharmaceuticals, Inc. helps to elucidate the scrutiny that courts may direct toward medical texts proffered as evidence. This article discusses the implications of different rules and relevant case law for the forensic psychiatrist. The discussion notes important considerations for the expert witness, such as how guidelines may affect the expert's role, concerns about the reliability and relevance of scientific evidence, and questions about whether guidelines will be used for inculpatory or exculpatory purposes in medical malpractice trials.

An intervention study conducted in the maternity hospital of Itapecerica da Serra, SP, with 50 puerperal women and 102 medical records from July to November 2014. The PACES tool from Joanna Briggs Institute, consisting of pre-clinical audit (phase 1), implementation of best practice (phase 2) and Follow-up Clinical Audit (phase 3) was used. Data were analyzed by comparing results of phases 1 and 3 with Fisher's exact test and a significance level of 5%. The vertical position was adopted by the majority of puerperal women with statistical difference between phases 1 and 3. A significant increase in bathing/showering, walking and massages for pain relief was found from the medical records. No statistical difference was found in other practices and outcomes. Barriers and difficulties in the implementation of evidence-based practices have been identified. Variables were refined, techniques and data collection instruments were verified, and an intervention proposal was made. The study found possibilities for implementing a methodology of practices based on scientific evidence for assistance in natural delivery.

    2011-12-01

    : INDEPTH field activities began in 1992 as a modest Sino-US reflection profile in the Tethyan Himalaya; after 20 years it has spanned the Tibet to cross the KunLun mountains. Three major field campaigns after the first modest test were each spring-boarded by a major discovery in the preceding phase, that in each case highlighted the value of a new scientific technique. INDEPTH-1 imaged the Main Himalayan Thrust for the first time, and wide-angle recording demonstrated India must penetrate north of the Indus-Tsangpo suture at mid-crustal levels. INDEPTH-2 additionally harnessed passive seismic and magneto-telluric recording to discover widespread crustal melting in the Lhasa terrane above subducting India, leading directly to the influential channel-flow model of the development of orogens. INDEPTH-3 crossed into the Qiangtang (northern Tibet), imaged the Indian slab descending into the mantle, and discovering the dramatic change in anisotropy properties of the lithosphere north and south of the Banggong-Nujiang suture. INDEPTH-4 focussed on the interaction of the Qaidam Basin with the high Tibetan plateau, by indentation into the weaker Tibetan crust of the Songpan-Ganzi terrane, and at greater depth provided new images of possible Asian subduction from the north beneath Tibet. Although INDEPTH has provided iconic images of the lithosphere, these have not always translated into agreement about fundamental concerns: the northern limit of Indian crust as part of Tibetan lithosphere (mantle suture) remains debated; and north of that mantle suture, the degree of crust-mantle coupling remains more in the realm of modelers than observational geophysics. Beyond the principal INDEPTH transect, dispersed MT studies in particular have been used to argue the essential collinearity of the Himalayan orogen, and these and passive seismic recordings have suggested relatively uniform plateau-wide processes controlled by a pervasively deforming crust. But as we have deployed more

    The study aims to illustrate the impact of Spanish research in clinical decision making. To this end, we analysed the characteristics of the most significant Spanish publications cited in clinical practice guidelines (CPG) on mental health. We conducted a descriptive qualitative study on the characteristics of ten articles cited in Spanish CPG on mental health, and selected for their "scientific quality". We analysed the content of the articles on the basis of the following characteristics: topics, study design, research centres, scientific and practical relevance, type of funding, and area or influence of the reference to the content of the guidelines. Among the noteworthy studies, some basic science studies, which have examined the establishment of genetic associations in the pathogenesis of mental illness are included, and others on the effectiveness of educational interventions. The content of those latter had more influence on the GPC, because they were cited in the summary of the scientific evidence or in the recommendations. Some of the outstanding features in the selected articles are the sophisticated designs (experimental or analytical), and the number of study centres, especially in international collaborations. Debate or refutation of previous findings on controversial issues may have also contributed to the extensive citation of work. The inclusion of studies in the CPG is not a sufficient condition of "quality", but their description can be instructive for the design of future research or publications.

    2013-01-01

    While numerous historiographical works have been written to shed light on Freud's early theoretical education in biology, physiology, and medicine and on the influence of that education on psychoanalysis, this paper approaches Freud's basic comprehension of science and methodology by focusing on his early research practice in physiology and neuranatomy. This practice, taking place in the specific context of Ernst Brücke's physiological laboratory in Vienna, was deeply concerned with problems of visuality and the revelation of hidden organic structures by use of proper preparation techniques and optical instruments. The paper explores the connection between such visualizing practices, shaped by a physiological context as they were, and Freud's later convictions of the scientific status of psychoanalysis and the function of its method as means to unveil the concealed structure of the "psychical apparatus". © 2013 Wiley Periodicals, Inc.

    CERN Document Server

    Cat, Jordi

    2017-01-01

    This book presents a comprehensive discussion on the characterization of vagueness in pictures. It reports on how the problem of representation of images has been approached in scientific practice, highlighting the role of mathematical methods and the philosophical background relevant for issues such as representation, categorization and reasoning. Without delving too much into the technical details, the book examines and defends different kinds of values of fuzziness based on a complex approach to categorization as a practice, adopting conceptual and empirical suggestions from different fields including the arts. It subsequently advances criticisms and provides suggestions for interpretation and application. By describing a cognitive framework based on fuzzy, rough and near sets, and discussing all of the relevant mathematical and philosophical theories for the representation and processing of vagueness in images, the book offers a practice-oriented guide to fuzzy visual reasoning, along with novel insights ...

    2016-01-01

    Full Text Available Purpose. Pharmaceutical industry is transnational and globally important. Many pharmaceutical companies operate their business in multinational and international forms in different countries. Diverse researches from different countries indicated and confirmed marketing promotion importance in pharmaceutical field. Therefore, marketing promotion and its effects are a very important issue that should be globally investigated in real life and evidence context. We oriented our research according to these scientific and practical values.Methodology. We reviewed pharmaceutical marketing promotion researches from more than 25 different countries, e.g., USA, Canada, Italy, France, Russia, India, Egypt and Syria where we employed our knowledge of three widely spread languages, i.e., English, Russian and Arabic. Such language variation supports us with large and variable amount of scientific knowledge, deep understanding and ability of analysis. Some studies investigated average response to pharmaceutical marketing promotion and few studies took into consideration heterogeneity in their effects with respect to advertising medium or drug characteristics.Originality. We investigated empirical evidences of pharmaceutical marketing promotion that can be directed to either consumer or healthcare professionals.Findings. We extracted, gathered and associated information of pharmaceutical promotion globally which oriented us to several evidence and practical facts with regard to employing promotion tools in different definite situations pertinent to main directions; their welfare and health enhancing effects and adverse effects. Practical Implications- Consequently, we developed practically-oriented guidelines for companies concerning pharmaceutical promotion globally ate the end of this paper.

  10. The Virtues of Scientific Practice: MacIntyre, Virtue Ethics, and the Historiography of Science.

    Science.gov (United States)

    Hicks, Daniel J; Stapleford, Thomas A

    2016-09-01

    “Practice” has become a ubiquitous term in the history of science, and yet historians have not always reflected on its philosophical import and in particular on its potential connections with ethics. This essay draws on the work of the virtue ethicist Alasdair MacIntyre to develop a theory of “communal practices” and explore how such an approach can inform the history of science, including allegations about the corruption of science by wealth or power, consideration of scientific ethics or “moral economies,” the role of values in science, the ethical distinctiveness (or not) of scientific vocations, and the relationship between history of science and the practice of science itself.

  13. Meaningful Engagement in Scientific Practices: How Classroom Communities Develop Authentic Epistemologies for Science

    Science.gov (United States)

    Krist, Christina Rae

    Recent reforms in science education, based on decades of learning research, emphasize engaging students in science and engineering practices as the means to develop and refine disciplinary ideas. These reforms advocate an epistemic shift in how school science is done: from students learning about science ideas to students figuring out core science ideas. This shift is challenging to implement: how do we bring the goals and practices of a discipline into classroom communities in meaningful ways that go beyond simply following rote scientific procedures? In this dissertation, I investigate how classroom communities learn to engage meaningfully in scientific practices, characterizing their engagement as a process of epistemic learning. I take a situated perspective that defines learning as shifts in how members engage in communities of practice. I examine students' epistemic learning as a function of their participation in a classroom community of scientific practice along two dimensions: what they do, or the practical epistemic heuristics they use to guide how they build knowledge; and who they are, or how ownership and authorship of ideas is negotiated and affectively marked through interaction. I focus on a cohort of students as they move from 6th to 8 th grade. I analyze three science units, one from each grade level, to look at the epistemic heuristics implicit in student and teacher talk and how the use of those heuristics shifts over time. In addition, I examine one anomalous 8th grade class to look at how students and the teacher position themselves and each other with respect to the ideas in their classroom and how that positioning supports epistemic learning. Taken together, these analyses demonstrate how students' engagement in scientific practices evolves in terms of what they do and who they are in relation to the knowledge and ideas in their classroom over time. I propose a model for epistemic learning that articulates how classroom communities develop

  14. A Whole Different Side of Geology: The Science of Reading and Mostly Understanding Scientific Articles for Beginning Geologists

    Figg, S.

    2014-12-01

    The idea of reading and understanding scientific articles can be daunting to beginning geology students. A student driven question "How do I read a scientific paper?" became the catalyst for a 1-unit special topic course, specifically devoted to the process of reading scientific articles. Five students participated in the course, which focused on research articles pertaining to an upcoming field study in Death Valley. The course was divided into four main portions: locating articles, reading and understand scientific articles, applying of articles in the field, and creating an abstract. Articles were located electronically through the Palomar College library. The first step was to teach students how to navigate databases for the desired material. Part Two was the most challenging and time consuming: the process of reading, analyzing, and comprehending scholarly articles. What made the course interesting was the student driven approach to the articles. Under guidance of an instructor, students worked as a group, navigating two different articles while developing their own strategies to obtain the basic concepts of the article. Each student then had to analyze an additional two articles of their choosing. During this time observations were made on student confidence, methods developed to assist in understanding articles, student challenges and successes. Information gained from the articles was then applied during a five day field course in Death Valley. Each student gave a brief presentation about the two articles read independently, applying them to various settings in the Death Valley region. Upon returning from the trip, students were tasked with contacting an author from one of the papers. The final portion of the special topic course was for students to produce their own abstracts, requiring them to condense a semester's worth of work into a short amount of words. From this 1-unit course, students learned there is no one way to read a scientific article, and

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

    2015-01-01

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

    2014-01-01

    The objective of this article is to examine the tensions that exist between care and custody in correctional environments by presenting the (im)possibilities of psychiatric nursing practice within this context. The analysis will be guided by empirical data obtained from a qualitative research conducted in a correctional setting. Semistructured interviews with nurses were conducted and used as the primary source of data for analysis. This article will explore the contextual characteristics of psychiatric nursing practice in correctional settings, describe the alienating effects of this context on nursing practice, theorize nurses' experience using Festinger's theory on cognitive dissonance, and, finally, explore how some nurses engage in the reconstruction of their care to counter the effects of working in correctional settings.

    Full Text Available In recent years the number of scholarly publications devoted to Kant's theory of biology has rapidly growing, with particular attention being given to Kant's thoughts about the concepts of teleology, function, organism, and their respective roles in scientific practice. Moving from these recent studies, and distancing itself from their mostly evolutionary background, the main aim of the present paper is to suggest an original "cognitive turn" in the interpretation of Kant's theory of biology. More specifically, the Authors will trace a connection between some Kantian theses about the “peculiar” or special nature of the human mind (intellectus ectypus, advanced in the Critique of the Power of Judgement (§ 76, 77, and some specific epistemological issues pertaining to the research practice of contemporary molecular biology.

    Looking at knowledge as a shared resource: experts discuss how to define, protect, and build the knowledge commons in the digital age. Knowledge in digital form offers unprecedented access to information through the Internet but at the same time is subject to ever-greater restrictions through intellectual property legislation, overpatenting, licensing, overpricing, and lack of preservation. Looking at knowledge as a commons―as a shared resource―allows us to understand both its limitless possibilities and what threatens it. In Understanding Knowledge as a Commons, experts from a range of disciplines discuss the knowledge commons in the digital era―how to conceptualize it, protect it, and build it. Contributors consider the concept of the commons historically and offer an analytical framework for understanding knowledge as a shared social-ecological system. They look at ways to guard against enclosure of the knowledge commons, considering, among other topics, the role of research libraries, the advantage...

  11. Fostering Scientific and Numerate Practices in Journalism to Support Rapid Public Learning

    Directory of Open Access Journals (Sweden)

    Louise Yarnall

    2017-01-01

    Full Text Available Journalism has the potential––and arguably the mandate––to expand public understanding of societally important phenomena. However, some methods for more effectively educating the public have been persistently underutilized: in particular, embedding informative numerical rates and efficient scientific explanations in news reports. In the current era of disrupting and downsizing the news business, the challenges to using such methods have only increased. To address this problem, this article seeks to (a raise awareness about the psychological reasons that help explain why it is crucial to use such elements in news reports, and (b exhibit some methods for doing so that require modest effort. Building on a review of relevant psychological literatures, principles, and existing reporting methods, we describe findings from a series of cognitive-scientific studies that demonstrate how using key––and relatively minimal––scientific and numerical elements can enhance public learning from news reports. We conclude by also describing curricula and resources designed to help journalists and bloggers use these methods.

    The collection of large quantities of scientific data has not only transformed science, but holds the potential to transform teaching and learning by engaging students in authentic scientific work. Furthermore, it has become imperative in a data-rich world that students gain competency in working with and interpreting data. The Next Generation Science Standards reflect both the opportunity and need for greater integration of data in science education, and emphasize that both scientific knowledge and practice are essential elements of science learning. The process of enabling access by novice learners to data collected and used by experts poses significant challenges, however, recent research has demonstrated that barriers to student learning with data can be overcome by the careful design of data access and analysis tools that are specifically tailored to students. A group of educators at Education Development Center, Inc. (EDC) and scientists at Stanford University's Hopkins Marine Station are collaborating to develop and test a model for student engagement with scientific data using a web-based platform. This model, called Ocean Tracks: Investigating Marine Migrations in a Changing Ocean, provides students with the ability to plot and analyze tracks of migrating marine animals collected through the Tagging of Pacific Predators program. The interface and associated curriculum support students in identifying relationships between animal behavior and physical oceanographic variables (e.g. SST, chlorophyll, currents), making linkages between the living world and climate. Students are also supported in investigating possible sources of human impact to important biodiversity hotspots in the Pacific Ocean. The first round of classroom testing revealed that students were able to easily access and display data on the interface, and collect measurements from the animal tracks and oceanographic data layers. They were able to link multiple types of data to draw powerful

    In many departments of General Practice (GP) in Germany, young doctors who are trainees also work as researchers. Often these trainees work part time at the university and part time as a trainee in clinical practice. However, little is known about the situation of the actors involved. The aim of the study was to investigate the perspectives of GP trainees, heads of departments and GP trainers regarding the combination of research and GP training. We conducted a web-based survey with the heads of all German departments of General Practice, GP trainees who also conduct research and their GP trainers. The questionnaires consisted of open and closed questions. The results were analyzed using descriptive statistics and qualitative methods. 28 heads of GP departments and 20 GP trainees responded. The trainees were mostly very satisfied with their situation as a trainee. However, the trainees considered the combination of research and GP training as difficult. The respondents name as problems the coordination of multiple jobs and the lack of credibility given to research in General Practice. They name as solutions research-enabling training programs and uniform requirements in training regarding research. The combination of GP training and scientific research activity is perceived as difficult. However, well-organized and designed programs can improve the quality of the combination.

Nurses are the largest health professional group and nurse graduates the main source of recruitment. The quality of graduate transition to practice is evident in the literature; however, little is reported about Indigenous new graduates. We describe using Indigenous methodology and two-eyed seeing (Indigenous and Western perspectives in exploring Indigenous transition experiences. Talking circles provided a safe environment for nurses, nurse educators and students, health managers, and policy makers to discuss Indigenous new graduate case scenarios. The methodology was critical in identifying challenges faced, recommendations for change, and a new collective commitment for cultural safety education, and ethical and respectful relationships within education, practice, and policy.

    Willett, Wesley; Goffin, Pascal; Isenberg, Petra

    2015-05-13

    We present results and design implications from a study of digital note-taking practice to examine how visualization can support revisitation, reflection, and collaboration around notes. As digital notebooks become common forms of external memory, keeping track of volumes of content is increasingly difficult. Information visualization tools can help give note-takers an overview of their content and allow them to explore diverse sets of notes, find and organize related content, and compare their notes with their collaborators. To ground the design of such tools, we conducted a detailed mixed-methods study of digital note-taking practice. We identify a variety of different editing, organization, and sharing methods used by digital note-takers, many of which result in notes becoming "lost in the pile''. These findings form the basis for our design considerations that examine how visualization can support the revisitation, organization, and sharing of digital notes.

  2. The measurement of the effect on citation inequality of differences in citation practices across scientific fields.

    Crespo, Juan A; Li, Yunrong; Li, Yungrong; Ruiz-Castillo, Javier

    2013-01-01

    This paper has two aims: (i) to introduce a novel method for measuring which part of overall citation inequality can be attributed to differences in citation practices across scientific fields, and (ii) to implement an empirical strategy for making meaningful comparisons between the number of citations received by articles in 22 broad fields. The number of citations received by any article is seen as a function of the article's scientific influence, and the field to which it belongs. A key assumption is that articles in the same quantile of any field citation distribution have the same degree of citation impact in their respective field. Using a dataset of 4.4 million articles published in 1998-2003 with a five-year citation window, we estimate that differences in citation practices between the 22 fields account for 14% of overall citation inequality. Our empirical strategy is based on the strong similarities found in the behavior of citation distributions. We obtain three main results. Firstly, we estimate a set of average-based indicators, called exchange rates, to express the citations received by any article in a large interval in terms of the citations received in a reference situation. Secondly, using our exchange rates as normalization factors of the raw citation data reduces the effect of differences in citation practices to, approximately, 2% of overall citation inequality in the normalized citation distributions. Thirdly, we provide an empirical explanation of why the usual normalization procedure based on the fields' mean citation rates is found to be equally successful.

    Full Text Available The paper gives a brief introduction to existential analysis (EA. It briefly describes how to develop this phenomenological approach and its main provisions. The emotion is deemed as a specific perception of a meaningful life. Emotionality plays a significant role in the existential analysis of anthropology and practice. The former one is the cornerstone of existence, and takes its place among the other three measurements in the existential theory of the EA. The paper presents a phenomenological description of the four-step process of the emotion emergence. It shows how during this process vitality is stimulated, so emotions are important to humans. This is an existential analytic theory of emotions, which explains the importance of the EA practice of affection feeling (fühlen and intuitive feeling (sense, i.e. spüren. The first is related to human life and the need for the detection values, the second one is related to the authenticity and ethics. In this pater, we consider the difference between the affect and the emotion.

    2015-01-01

    Uterine leiomyomas (fibroids) are the most prevalent medical problem of the female reproductive tract, but there are few non-surgical treatment options. Although many advances in the understanding of the molecular components of these tumors have occurred over the past five years, an effective pharmaceutical approach remains elusive. Further, there is currently no clinical method to distinguish a benign uterine leiomyoma from a malignant leiomyosarcoma prior to treatment, a pressing need given concerns about the use of the power morcellator for minimally invasive surgery. This paper reviews current studies regarding the molecular biology of uterine fibroids, discusses non-surgical approaches and suggests new cutting-edge therapeutic and diagnostic approaches.

Knowledge of models is linked to other important nature of science concepts such as theory change which are also rising in prominence in newer standards. Effective methods of instruction will need to be developed to enable students to achieve these standards. The literature reveals an inconsistent history of success with modeling education. These same studies point to a possible cognitive development component which might explain why some students succeeded and others failed. An environmental science course, rich in modeling experiences, was used to test both the extent to which knowledge of models and modeling could be improved over the course of one semester, and more importantly, to identify if cognitive ability was related to this improvement. In addition, nature of science knowledge, particularly related to theories and theory change, was also examined. Pretest and posttest results on modeling (SUMS) and nature of science (SUSSI), as well as data from the modeling activities themselves, was collected. Cognitive ability was measured (CTSR) as a covariate. Students' gain in six of seven categories of modeling knowledge was at least medium (Cohen's d >.5) and moderately correlated to CTSR for two of seven categories. Nature of science gains were smaller, although more strongly correlated with CTSR. Student success at creating a model was related to CTSR, significantly in three of five sub-categories. These results suggest that explicit, reflective experience with models can increase student knowledge of models and modeling (although higher cognitive ability students may have more success), but successfully creating models may depend more heavily on cognitive ability. This finding in particular has implications in the grade placement of modeling standards and

    Applying scientific knowledge to confront societal challenges is a difficult task, an issue known as the science-practice gap. In Ecology and Conservation, scientific evidence has been seldom used directly to support decision-making, despite calls for an increasing role of ecological science in developing solutions for a sustainable future. To date, multiple causes of the science-practice gap and diverse approaches to link science and practice in Ecology and Conservation have been proposed. To foster a transparent debate and broaden our understanding of the difficulties of using scientific knowledge, we reviewed the perceived causes of the science-practice gap, aiming to: (i) identify the perspectives of ecologists and conservation scientists on this problem, (ii) evaluate the predominance of these perspectives over time and across journals, and (iii) assess them in light of disciplines studying the role of science in decision-making. We based our review on 1563 sentences describing causes of the science-practice gap extracted from 122 articles and on discussions with eight scientists on how to classify these sentences. The resulting process-based framework describes three distinct perspectives on the relevant processes, knowledge and actors in the science-practice interface. The most common perspective assumes only scientific knowledge should support practice, perceiving a one-way knowledge flow from science to practice and recognizing flaws in knowledge generation, communication, and/or use. The second assumes that both scientists and decision-makers should contribute to support practice, perceiving a two-way knowledge flow between science and practice through joint knowledge-production/integration processes, which, for several reasons, are perceived to occur infrequently. The last perspective was very rare, and assumes scientists should put their results into practice, but they rarely do. Some causes (e.g. cultural differences between scientists and decision

    Interdisciplinary teams in rehabilitation are effective for positive patient outcomes. They require skills in team building and interprofessional collaboration. The Institute of Medicine has interdisciplinary teams as one of the five core competencies for healthcare workers. In reviewing the literature on teams, several themes were developed, such as communication, collaboration, understanding of roles, and educational levels of team members. Using these themes, a survey was developed to assess perceptions of teams by rehabilitation nurses, physical therapists, and occupational therapists. Significant findings came from questions on educational levels of team members between nurses and occupational therapists and also within the nursing groups. Open-ended questions asked about barriers and facilitators for effective teams. We hope that these pilot results will lead to discussions on how to improve interdisciplinary teams and make them more effective for better patient outcomes. © 2013 Association of Rehabilitation Nurses.

Introducing the universe and diversity in the mathematics and science area with a short course aimed to studies of particles analysis, viscosity and permeability, this initiative encompasses more than knowledge of these activities, but also restore the link between school and university, inserting the high school students in the university environment and scientific activities. The importance of providing a "north" for teens, due to the great difficulty of choosing their profession, makes this Extension Project a potential tool that will certainly contribute to the professional future of these young citizens. Therefore, the students had a laboratory experience and also it was possible to motivate them to go further in the superior education through the awareness that university is accessible to all of people.

    As scientific computing applications grow in complexity, more and more functionality is being packaged in independently developed libraries. Worse, as the computing environments in which these applications run grow in complexity, it gets easier to make mistakes in building, installing and using libraries as well as the applications that depend on them. Unfortunately, SQA standards so far developed focus primarily on applications, not libraries. We show that SQA standards for libraries differ from applications in many respects. We introduce and describe a variety of practices aimed at minimizing the likelihood of making mistakes in using libraries and at maximizing users' ability to diagnose and correct them when they occur. We introduce the term Smart Library to refer to a library that is developed with these basic principles in mind. We draw upon specific examples from existing products we believe incorporate smart features: MPI, a parallel message passing library, and HDF5 and SAF, both of which are parallel I/O libraries supporting scientific computing applications. We conclude with a narrative of some real-world experiences in using smart libraries with Ale3d, VisIt and SAF.

  15. Supporting students' scientific explanations: A case study investigating the synergy focusing on a teacher's practices when providing instruction and using mobile devices

    Delen, Ibrahim

    Engage students in constructing scientific practices is a critical component of science instruction. Therefore a number of researchers have developed software programs to help students and teachers in this hard task. The Zydeco group, designed a mobile application called Zydeco, which enables students to collect data inside and outside the classroom, and then use the data to create scientific explanations by using claim-evidence-reasoning framework. Previous technologies designed to support scientific explanations focused on how these programs improve students' scientific explanations, but these programs ignored how scientific explanation technologies can support teacher practices. Thus, to increase our knowledge how different scaffolds can work together, this study aimed to portray the synergy between a teacher's instructional practices (part 1) and using supports within a mobile devices (part 2) to support students in constructing explanations. Synergy can be thought of as generic and content-specific scaffolds working together to enable students to accomplish challenging tasks, such as creating explanations that they would not normally be able to do without the scaffolds working together. Providing instruction (part 1) focused on understanding how the teacher scaffolds students' initial understanding of the claim-evidence-reasoning (CER) framework. The second component of examining synergy (part 2: using mobile devices) investigated how this teacher used mobile devices to provide feedback when students created explanations. The synergy between providing instruction and using mobile devices was investigated by analyzing a middle school teacher's practices in two different units (plants and water quality). Next, this study focused on describing how the level of synergy influenced the quality of students' scientific explanations. Finally, I investigated the role of focused teaching intervention sessions to inform teacher in relation to students' performance. In

    Guidelines recommend the use of evidence-based practice in nursing. Nurses are expected to give patients care and treatment based on the best knowledge available. They may have knowledge and positive attitudes, but this does not mean that they are basing their work on evidence-based practice. Knowledge is still lacking about what is needed to successfully implement evidence-based practice. The aim of this study was to gain more knowledge about what nurses perceive as the most important challenge in implementing evidence-based practice and to explain how they act to face and overcome this challenge. We used classical grounded theory methodology and collected data through four focus groups and one individual interview in different geographical locations in one large hospital trust in Norway. Fourteen registered clinical practice nurses participated. We analysed the data in accordance with grounded theory, using the constant comparative method. Contextual balancing of knowledge emerged as the core category and explains how the nurses dealt with their main concern, how to determine what types of knowledge they could trust. The nurses' main strategies were an inquiring approach, examining knowledge and maintaining control while taking care of patients. They combined their own experienced-based knowledge and the guidelines of evidence-based practice with a sense of control in the actual situation. The grounded theory contextual balancing of knowledge may help us to understand how nurses detect what types of knowledge they can trust in clinical practice. The nurses needed to rely on what they did, and they seemed to rely on their own experience rather than on research. © 2015 Nordic College of Caring Science.

    The Merapi volcano is of great interest to a wide audience as it is one of the most dangerous volcanoes worldwide and a beautiful touristic spot. The scientific literature available on that volcano both in Earth and Social sciences is rich but mostly inaccessible to the public because of the scientific jargon and the restricted database access. Merapi Interactive aims at developing clear information and attractive content about Merapi for a wide audience. The project is being produced by the Art and Media Group at the Earth Observatory of Singapore, and it takes the shape of an e-book. It offers a consistent, comprehensive, and jargon-filtered synthesis of the main volcanic-risk related topics about Merapi: volcanic mechanisms, eruptive history, associated hazards and risks, the way inhabitants and scientists deal with it, and what daily life at Merapi looks like. The project provides a background to better understand volcanoes, and it points out some interactions between scientists and society. We propose two levels of interpretation: one that is understandable by 10-year old kids and above and an expert level with deeper presentations of specific topics. Thus, the Merapi Interactive project intends to provide an engaging and comprehensive interactive book that should interest kids, adults, as well as Earth Sciences undergraduates and academics. Merapi Interactive is scheduled for delivery in mid-2016.

    This report describes molecular techniques that could be invaluable in addressing process-oriented problems in the ocean sciences that have perplexed oceanographers for decades, such as understanding the basis for biogeochemical processes, recruitment processes, upper-ocean dynamics, biological impacts of global warming, and ecological impacts of human activities. The coupling of highly sophisticated methods, such as satellite remote sensing, which permits synoptic monitoring of chemical, physical, and biological parameters over large areas, with the power of modern molecular tools for ``ground truthing`` at small scales could allow scientists to address questions about marine organisms and the ocean in which they live that could not be answered previously. Clearly, the marine sciences are on the threshold of an exciting new frontier of scientific discovery and economic opportunity.

    2018-01-02

    This paper reviews the origin and chemical and rheological complexity of radioactive waste at the U.S. Department of Energy’s Hanford Site. The waste, stored in underground tanks, was generated via three distinct processes over decades of plutonium extraction operations. Although close records were kept of original waste disposition, tank-to-tank transfers and conditions that impede equilibrium complicate our understanding of the chemistry, phase composition, and rheology of the waste. Tank waste slurries comprise particles and aggregates from nano to micron scales, with varying densities, morphologies, heterogeneous compositions, and complicated responses to flow regimes and process conditions. Further, remnant or changing radiation fields may affect the stability and rheology of the waste. These conditions pose challenges for transport through conduits or pipes to treatment plants for vitrification. Additionally, recalcitrant boehmite degrades glass quality and must be reduced prior to vitrification, but dissolves much more slowly than predicted given surface normalized rates. Existing empirical models based on ex situ experiments and observations lack true predictive capabilities. Recent advances in in situ microscopy, aberration corrected TEM, theoretical modeling across scales, and experimental methods for probing the physics and chemistry at mineral-fluid and mineral-mineral interfaces are being implemented to build robustly predictive physics-based models.

    The objective of this manuscript is to describe the process through which bench-top research is incorporated into clinical practice from an evidence-based dentistry perspective. Relevant literature is reviewed to describe the translation of bench-top research to clinical practice through the steps of preclinical testing; human clinical trials; systematic review development (question development, search/screen methods, evidence synthesis, and evidence appraisal); clinical recommendation development; dissemination strategies; the role of the clinician in finding and appraising relevant evidence; barriers to implementation with strategies to overcome those barriers; and finally, the fusion of evidence with clinician experience and patient needs and preferences in clinical decision-making. Descriptions of processes, methodologies, tools, and resources are provided to help researchers and clinicians alike understand the steps that lie between bench-top research and clinical implementation. With mutual understanding of the complexity involved in translating research into practice, it is hoped that barriers to implementation can be overcome that should lead to improved patient health outcomes.

    Given the emerging global childhood obesity epidemic and the specter of a generation of children who will have a shorter life expectancy than that of their parents, recent research has focused on factors that influence children's weight status and obesogenic behaviors (i.e., eating, physical activity, and screen media use). Parents act as primary socializing agents for children, and thus growing evidence supports the role of parenting styles and practices in children's obesity-related behaviors and weight. Studying these processes in children and adolescents is important for several reasons. First, diet and physical activity behaviors and weight status track from childhood and adolescence into adulthood. Furthermore, diet and physical activity behaviors and weight status confer significant risk for cancer, diabetes, cardiovascular disease, and other chronic diseases. The purpose of this article is to describe the scientific gaps that need to be addressed to develop a more informed literature on parenting styles and practices in the domains of weight status and obesogenic behaviors, as identified by an expert panel assembled by the National Cancer Institute.

  4. Scientists in the making: An ethnographic investigation of scientific processes as literate practice in an elementary classroom

    Crawford, Teresa Jo

    This study explored the issue of literacy in science by examining how the social and academic literate practices in an elementary classroom formed the basis for learning across the curriculum, with a specific focus on the disciplinary field of science. Through the study of classroom interaction, issues related to student knowledge and ability were addressed as they pertain to scientific literacy in the context of science education reform. The theoretical framework guiding this study was drawn from sociocultural studies of scientific communities and interactional ethnography in education. To investigate the literate practices of science in a school setting, data were collected over a two-year period with the same teacher in her third grade and then her fourth/fifth grade classroom. Data were collected through participant observation in the form of fieldnotes, video data, interviews, and various artifacts (e.g., writings, drawings, teaching protocols). Using ethnographic and sociolinguistic methods of analysis this work examined classroom members' discursive practices to illustrate the role that discourse plays in creating opportunities for engagement in, and access to, scientific knowledge. These analyses revealed that the discursive actions and practices among members of this classroom shaped a particular type of learning environment that was process-oriented and inquiry based. It was shown that this learning environment afforded opportunities for students to engage in the processes of science outside the official, planned curriculum, often leading to whole class scientific investigations and discussions. Additionally, within this classroom community students were able to draw on multiple discourses to display their knowledge of scientific concepts and practices. Overall, this study found that the literate practices of this classroom community, as they were socially constructed among members, contributed to opportunities for students to practice science and

    2017-08-01

    Uncertainty is recognized as a key issue in water resources research, among other sciences. Discussions of uncertainty typically focus on tools and techniques applied within an analysis, e.g., uncertainty quantification and model validation. But uncertainty is also addressed outside the analysis, in writing scientific publications. The language that authors use conveys their perspective of the role of uncertainty when interpreting a claim—what we call here "framing" the uncertainty. This article promotes awareness of uncertainty framing in four ways. (1) It proposes a typology of eighteen uncertainty frames, addressing five questions about uncertainty. (2) It describes the context in which uncertainty framing occurs. This is an interdisciplinary topic, involving philosophy of science, science studies, linguistics, rhetoric, and argumentation. (3) We analyze the use of uncertainty frames in a sample of 177 abstracts from the Water Resources Research journal in 2015. This helped develop and tentatively verify the typology, and provides a snapshot of current practice. (4) We make provocative recommendations to achieve a more influential, dynamic science. Current practice in uncertainty framing might be described as carefully considered incremental science. In addition to uncertainty quantification and degree of belief (present in ˜5% of abstracts), uncertainty is addressed by a combination of limiting scope, deferring to further work (˜25%) and indicating evidence is sufficient (˜40%)—or uncertainty is completely ignored (˜8%). There is a need for public debate within our discipline to decide in what context different uncertainty frames are appropriate. Uncertainty framing cannot remain a hidden practice evaluated only by lone reviewers.

    The main purpose of this study was to explore learners' beliefs about science reading and scientific epistemic beliefs, and how these beliefs were associating with their understanding of science texts. About 400 10th graders were involved in the development and validation of the Beliefs about Science Reading Inventory (BSRI). To find the effects of reader beliefs and epistemic beliefs, a new group of 65 10th grade students whose reader and epistemic beliefs were assessed by the newly developed BSRI and an existing SEB questionnaire were invited to take part in a science reading task. Students' text understanding in terms of concept gain and text interpretations was collected and analyzed. By the correlation analysis, it was found that when students had stronger beliefs about meaning construction based on personal goals and experiences (i.e. transaction beliefs), they produced more thematic and critical interpretations of the content of the test article. The regression analysis suggested that students SEBs could predict concept gain as a result of reading. Moreover, among all beliefs examined in the study, transaction beliefs stood out as the best predictor of overall science-text understanding.

    Recommendations (best practices) are provided by the Society of Toxicologic Pathology's Adversity Working Group for making consistent interpretations of test article-related effects as "adverse" and assigning a "no observed adverse effect level" (NOAEL) in nonclinical toxicity studies. Adverse is a term indicating "harm" to the test animal, while nonadverse indicates lack of harm. Adverse findings in the study reports should be defined in relation to effects on the test species used and within the context of the given study. Test article-related effects should be described on their own merits, and decisions to consider them as adverse or nonadverse should be justified. Related effects may be discussed together; in particular, markers of toxicity that are not in and of themselves adverse ideally should be discussed in conjunction with the causal toxicity to determine adversity. Adverse findings should be identified in subreports (clinical data, pathology data, etc.) if sufficient information is available, and/or in the final study report as individual or grouped findings, but study NOAELs should be established at the level of the overall study report. Interpretations such as "not biologically relevant" or "not toxicologically important" should be avoided unless defined and supported by scientific rationale. Decisions defining adverse findings and the NOAEL in final study reports should combine the expertise of all contributing scientific disciplines. Where possible, use of NOAELs in data tables should be linked to explanatory text that places them in context. Ideally, in nonclinical summary documents, NOAELs from multiple studies are considered together in defining the most important adverse responses in the most sensitive species. These responses are then considered along with an understanding of their likely mechanisms, as well as other information such as variability in species sensitivity, comparative pathology, reversibility and progression, kinetics, and

    2011-01-01

    This article suggests that the discourse on arts and health encompass contemporary arts practices as an active and engaged analytical activity. Distinctions between arts therapy and arts practice are made to suggest that clinical evidence-based evaluation, while appropriate for arts therapy, is not appropriate for arts practice and in effect cast them in unreasonable doubt. Themes in current discourse on “arts” and “health” are broadly sketched to provide a context for discussion of arts practices. Approaches to knowledge validation in relation to each domain are discussed. These discourses are applied to the Irish healthcare context, offering a reading of three different art projects; it suggests a multiplicity of analyses beyond causal positive health gains. It is suggested that the social turn in medicine and the social turn in arts practices share some similar pre-occupations that warrant further attention. PMID:22675403

  2. Scientific and practical tools for dealing with water resource estimations for the future

    2015-06-01

    Full Text Available Future flow regimes will be different to today and imperfect knowledge of present and future climate variations, rainfall–runoff processes and anthropogenic impacts make them highly uncertain. Future water resources decisions will rely on practical and appropriate simulation tools that are sensitive to changes, can assimilate different types of change information and flexible enough to accommodate improvements in understanding of change. They need to include representations of uncertainty and generate information appropriate for uncertain decision-making. This paper presents some examples of the tools that have been developed to address these issues in the southern Africa region. The examples include uncertainty in present day simulations due to lack of understanding and data, using climate change projection data from multiple climate models and future catchment responses due to both climate and development effects. The conclusions are that the tools and models are largely available and what we need is more reliable forcing and model evlaution information as well as methods of making decisions with such inevitably uncertain information.

  3. Taking the Scientist's Perspective - The Nonfiction Narrative Engages Episodic Memory to Enhance Students' Understanding of Scientists and Their Practices

    2018-03-01

    The Next Generation Science Standards (NGSS Lead States 2013) mandates that schools provide students an understanding of the skills and knowledge that scientists use to engage in scientific practices. In this article, I argue that one of the best ways to accomplish this goal is to have students take the perspective of the scientist by reading nonfiction narratives written by scientists and science writers. I explore the anthropological and neurological evidence that suggests that perspective-taking is an essential component in the learning process. It has been shown that by around age 4, the human child begins to be able to take the perspective of others—a process that neuroscientists have shown engages episodic memory, a memory type that some neurocognitive scientists believe is central in organizing human cognition. Neuroscientists have shown that the brain regions in which episodic memory resides undergo pronounced anatomical changes during adolescence, suggesting that perspective-taking assumes an even greater role in cognition during adolescence and young adulthood. Moreover, I argue that the practice of science itself is narrative in nature. With each new observation and experiment, the scientist is acting to reveal an emerging story. It is the story-like nature of science that motivates the scientist to push onward with new experiments and new observations. It is also the story-like nature of the practice of science that can potentially engage the student. The classroom studies that I review here confirm the power of the narrative in increasing students' understanding of science.

    2012-09-01

    Full Text Available This article aims to analyze the perception of a franchise on building strategies located around practices experienced by referencing franchisor's standards and regional reality. There is a complexity in the relationship between franchisee and franchisor in a franchise system and its implications in the strategies developed by these actors. This qualitative research adopted the theoretical approach called Strategy as Practice, which seeks to understand the strategy considering its stakeholders (practitioners, practices established and incorporated in addition to the practice that represents the effective implementation of strategic actions, socially constructed and reconstructed. For data collection, in-depth open interviews were conducted with the owner of two franchise stores, located in a city in the Brazil´s Northeast. The data were analyzed and categorized according to feedback from the franchisee on how he responds to practices imposed by the franchise system. As a result, four categories were identified that represent relevant practices: workshops sponsored by the franchisor, the franchisee's annual planning, visiting consultants, and business strategies for sales. It was concluded that although there is considerable control of the franchisor on its franchisees, many of the practices of the franchise system are adapted and transformed in practice by the franchisee, often in a different way than was originally imposed. We emphasize the importance of strategy as practice approach in understanding the construction and interpretation of the strategy in a franchise system based on social relationships developed in this system.

    2012-01-01

    Full Text Available Background: Adequate nutritional support is important for the comprehensive management of patients in intensive care units (ICUs. Aim: The study was aimed to survey prevalent enteral nutrition practices in the trauma intensive care unit, nurses′ perception, and their knowledge of enteral feeding. Study Design: The study was conducted in the ICU of a level 1 trauma center, Jai Prakash Narayan Apex Trauma Centre, AIIMS, New Delhi, India. The study design used an audit. Materials and Methods: Sixty questionnaires were distributed and the results analyzed. A database was prepared and the audit was done. Results: Forty-two (70% questionnaires were filled and returned. A majority (38 of staff nurses expressed awareness of nutrition guidelines. A large number (32 of staff nurses knew about nutrition protocols of the ICU. Almost all (40 opined enteral nutrition to be the preferred route of nutrition unless contraindicated. All staff nurses were of opinion that enteral nutrition is to be started at the earliest (within 24-48 h of the ICU stay. Everyone opined that the absence of bowel sounds is an absolute contraindication to initiate enteral feeding. Passage of flatus was considered mandatory before starting enteral nutrition by 86% of the respondents. Everyone knew that the method of Ryle′s tube feeding in their ICU is intermittent boluses. Only 4 staff nurses were unaware of any method to confirm Ryle′s tube position. The backrest elevation rate was 100%. Gastric residual volumes were always checked, but the amount of the gastric residual volume for the next feed to be withheld varied. The majority said that the unused Ryle′s tube feed is to be discarded after 6 h. The most preferred (48% method to upgrade their knowledge of enteral nutrition was from the ICU protocol manual. Conclusion: Information generated from this study can be helpful in identifying nutrition practices that are lacking and may be used to review and revise enteral feeding

  9. Understanding health through social practices: performance and materiality in everyday life.

    Maller, Cecily Jane

    2015-01-01

    The importance of recognising structure and agency in health research to move beyond methodological individualism is well documented. To progress incorporating social theory into health, researchers have used Giddens' and Bourdieu's conceptualisations of social practice to understand relationships between agency, structure and health. However, social practice theories have more to offer than has currently been capitalised upon. This article delves into contemporary theories of social practice as used in consumption and sustainability research to provide an alternative, and more contextualised means, of understanding and explaining human action in relation to health and wellbeing. Two key observations are made. Firstly, the latest formulations of social practice theory distinguish moments of practice performance from practices as persistent entities across time and space, allowing empirical application to explain practice histories and future trajectories. Secondly, they emphasise the materiality of everyday life, foregrounding things, technologies and other non-humans that cannot be ignored in a technologically dependent social world. In concluding, I argue the value of using contemporary social practice theories in health research is that they reframe the way in which health outcomes can be understood and could inform more effective interventions that move beyond attitudes, behaviour and choices. © 2015 The Authors.

    2017-01-01

    Thermal comfort is central to energy consumption in housing and one of the main drivers behind worldwide GHG emissions. Research on residential energy consumption has therefore addressed comfort in relation to indoor temperatures. This paper argues that by widening the focus of comfort to include...... other aspects such as air, light and materials, more sustainable ideas of residential comfort might be developed. The paper takes a practice theoretical perspective but argues that the senses should be better incorporated into the approach to understand different aspects of comfort. The paper...... investigates how comfort can be understood as sensorial within theories of practice. This implies understanding how the senses are incorporated in embodied and routinised social practices, through which comfort is sensed and interpreted. Comfort is related to a range of everyday practices in the home...

    Kubesová, H; Holik, J; Bogrova, I

    2001-01-01

    It has been proven that with an increasing number of diseases elderly patients are treated by an increasing number of drugs despite the fact that treatment of elderly persons should be as simple as possible. Simpler dosage of (fewer?) drugs may contribute to a good cooperation on the part of patients, as well as to a lower incidence of undesirable effects and drug interactions. Sticking to established medication schemes is another feature observed in practice, which interferes with the introduction of novelties. The aim of this study was to investigate the actual situation of medication of elderly patients treated by general practitioners in this country. Between 1996 and 1998, a random group of 1481 patients aged older than 75 was studied in cooperation with general practitioners. A detailed history was obtained and physical examination was performed, signs of depression were assessed, Barthel's test of everyday activities, and IADL (activities of daily living) and MMSE (Mini Mental State Examination) tests were applied. A unified "Protocol on Examination" was used in which three questions were concerned with medication--the kinds of drugs taken by the patient, their names and dosage, and whether any hypnotics were taken. The five most frequently prescribed groups include vasodilators (62% patients), cardiotonics (39%), analgetics (41%) and Ca-antagonists (25%). The dynamics of the prescription were remarkable--a significant decrease of the use of analgetics and cardiotonics was observed in comparison with a significant increase in the use of ACE inhibitors. The number of drugs administered is as follows: while only 1.3% patients took no drugs, 1.6% patients took more than 13 drugs. 61% patients rank among the categories taking 4-5 or 6-8 kinds of drugs. On the whole, general practitioners tend to prescribe medicaments in doses one tablet per day. The results suggest that, even nowadays, elderly patients are treated with a rather high number of medicaments. In

    Evidence-based practice (EBP) has become a central focus in clinical child and adolescent psychology. As originally defined, EBP in psychology is the integration of the best available research evidence, patient characteristics, and clinical expertise. Although evidence-based perspectives have garnered widespread acceptance in recent years, there has also been some confusion and disagreement about the 3-part definition of EBP, particularly the role of research. In this article, we first provide a brief review of the development of EBP in clinical child and adolescent psychology. Next, we outline the following 4 points to help clarify the understanding of EBP: (a) knowledge should not be confused with epistemic processes, (b) research on clinician and client factors is needed for EBP, (c) research on assessment is needed for EBP, and (d) the 3-part conceptualization of EBP can serve as a useful framework to guide research. Based on these principles, we put forth a slightly revised conceptualization of EBP, in which the role of research is expanded and more clearly operationalized. Finally, based on our review of the literature, we offer illustrative examples of specific directions for future research to advance the evidence base for EBP in clinical child and adolescent psychology.

    To provide empirical evidence on key organizing constructs shaping practical, real-world integration of behavior health and primary care to comprehensively address patients' medical, emotional, and behavioral health needs. In a comparative case study using an immersion-crystallization approach, a multidisciplinary team analyzed data from observations of practice operations, interviews, and surveys of practice members, and implementation diaries. Practices were drawn from 2 studies of practices attempting to integrate behavioral health and primary care: Advancing Care Together, a demonstration project of 11 practices located in Colorado, and the Integration Workforce Study, a study of 8 practices across the United States. We identified 5 key organizing constructs influencing integration of primary care and behavioral health: 1) Integration REACH (the extent to which the integration program was delivered to the identified target population), 2) establishment of continuum of care pathways addressing the location of care across the range of patient's severity of illness, 3) approach to patient transitions: referrals or warm handoffs, 4) location of the integration workforce, and 5) participants' mental model for integration. These constructs intertwine within an organization's historic and social context to produce locally adapted approaches to integrating care. Contextual factors, particularly practice type, influenced whether specialty mental health and substance use services were colocated within an organization. Interaction among 5 organizing constructs and practice context produces diverse expressions of integrated care. These constructs provide a framework for understanding how primary care and behavioral health services can be integrated in routine practice. © Copyright 2015 by the American Board of Family Medicine.

    Understanding the main values and beliefs that might promote humanized birth practices in the specialized hospitals requires articulating the theoretical knowledge of the social and cultural characteristics of the childbirth field and the relations between these and the institution. This paper aims to provide a conceptual framework allowing examination of childbirth practices through the lens of an organizational culture theory. A literature review performed to extrapolate the social and cultural factors contribute to birth practices and the factors likely overlap and mutually reinforce one another, instead of complying with the organizational culture of the birth place. The proposed conceptual framework in this paper examined childbirth patterns as an organizational cultural phenomenon in a highly specialized hospital, in Montreal, Canada. Allaire and Firsirotu's organizational culture theory served as a guide in the development of the framework. We discussed the application of our conceptual model in understanding the influences of organizational culture components in the humanization of birth practices in the highly specialized hospitals and explained how these components configure both the birth practice and women's choice in highly specialized hospitals. The proposed framework can be used as a tool for understanding the barriers and facilitating factors encountered birth practices in specialized hospitals.

    Purpose The significant individual and societal burden of work disability could be reduced if supportive workplace strategies could be added to evidence-based clinical treatment and rehabilitation to improve return-to-work (RTW) and other disability outcomes. The goal of this article is to summarize existing research on workplace interventions to prevent disability, relate these to employer disability management practices, and recommend future research priorities. Methods The authors participated in a year-long collaboration that ultimately led to an invited 3-day conference, Improving Research of Employer Practices to Prevent Disability, held October 14-16, 2015, in Hopkinton, Massachusetts, USA. The collaboration included a topical review of the literature, group conference calls to identify key areas and challenges, drafting of initial documents, review of industry publications, and a conference presentation that included feedback from peer researchers and a question/answer session with an expert panel with direct employer experience. Results Evidence from randomized trials and other research designs has shown general support for job modification, RTW coordination, and organizational support, but evidence is still lacking for interventions at a more granular level. Grey literature reports focused mainly on job re-design and work organization. Panel feedback focused on organizational readiness and the beliefs and values of senior managers as critical factors in facilitating changes to disability management practices. While the scientific literature is focused on facilitating improved coping and reducing discomforts for individual workers, the employer-directed grey literature is focused on making group-level changes to policies and procedures. Conclusions Future research might better target employer practices by tying interventions to positive workplace influences and determinants, by developing more participatory interventions and research designs, and by

    With the copious amount of science and pseudoscience reported on by non-experts in the media, it is critical for educators to help students develop into scientifically literate citizens. One of the most direct ways to help students develop deep scientific understanding and the skills to critically question the information they encounter is to bring science into their daily experiences and to contextualize scientific inquiry within the classroom. Our work aims to use a systems-based models approach to engage students in science, in both formal and informal contexts. Using the Understanding Global Change (UGC) and the Understanding Science models developed at the Museum of Paleontology at UC Berkeley, high school students from Arizona were tasked with developing a viable citizen science program for use at the Center for Alaskan Coastal Studies in Homer, Alaska. Experts used the UGC model to help students define why they were doing the work, and give context to the importance of citizen science. Empowered with an understanding of the scientific process, excited by the purpose of their work and how it could contribute to the scientific community, students whole-heartedly worked together to develop intertidal monitoring protocols for two locations while staying at Peterson Bay Field Station, Homer. Students, instructors, and scientists used system models to communicate and discuss their understanding of the biological, physical, and chemical processes in Kachemak Bay. This systems-based models approach is also being used in an integrative high school physics, chemistry, and biology curriculum in a truly unprecedented manner. Using the Understanding Global Change framework to organize curriculum scope and sequence, the course addresses how the earth systems work, how interdisciplinary science knowledge is necessary to understand those systems, and how scientists and students can measure changes within those systems.

    Implementing changes in practice in either clinical or educational settings remains challenging. In the context of Information and Communication Technologies (ICT) adoption, the literature focuses either on organisational factors influencing its implementation, or on individual factors influencing its adoption into practice. Separately both fail to examine the issue holistically. Bourdieu's theory of practice provides a method for reconciling the two. To provide a practical example of how Bourdieu's theory of practice can be employed to better understand nurse educators' responses to ICT. Exploratory descriptive design, using a Bourdieusian case-study to guide a documentary analysis. In 2009 a two-part study was conducted within a Department of Nursing (DON) in higher education (HE) in England. First Bourdieu's theory of practice was used to develop a case-study; then nurse educators were recruited for a Q-methodology (Q) study. This paper focuses exclusively on the case study and the use of the theory of practice to interpret the findings from the Q-study. Nursing's transition into academia, promotions criteria in HE and the value placed on research over teaching have influenced educators' responses to technology. The use of Bourdieu's framework provides a rich and contextual backdrop for understanding how organisational factors interact to influence individuals' responses to technology adoption.

    For most experimental biologists, handling the avalanche of data generated is similar to self-learn how to drive. Although that might be doable, it is preferable and safer to learn good practices. One way to achieve this is to build local communities of practice by bringing together scientists that perform code-intensive research to spread know-how and good practices. Here, we indicate important challenges and issues that stand in the way of establishing these local communities of practice. F...

    Elementary teachers play a crucial role in supporting and scaffolding students' model-based reasoning about natural phenomena, particularly complex systems such as the water cycle. However, little research exists to inform efforts in supporting elementary teachers' learning to foster model-centered, science learning environments. To address this need, we conducted an exploratory multiple-case study using qualitative research methods to investigate six 3rd-grade teachers' pedagogical reasoning and classroom instruction around modeling practices (construct, use, evaluate, and revise) and epistemic considerations of scientific modeling (generality/abstraction, evidence, mechanism, and audience). Study findings show that all teachers emphasized a subset of modeling practices-construction and use-and the epistemic consideration of generality/abstraction. There was observable consistency between teachers' articulated conceptions of scientific modeling and their classroom practices. Results also show a subset of the teachers more strongly emphasized additional epistemic considerations and, as a result, better supported students to use models as sense-making tools as well as representations. These findings provide important evidence for developing elementary teacher supports to scaffold students' engagement in scientific modeling.

    The study dwells on the scientific background of Carlos Chagas Filho, between 1926 and 1942, which was the period of socialization of the scientist in the Faculdade de Medicina do Rio de Janeiro and the Instituto Oswaldo Cruz. It covers the period from the beginning of his professional career to the moment when he resigned from the administration of the Serviço de Estudos de Grandes Endemias in 1942 to devote himself to his academic career at the Laboratório de Física Biológica. The way in which his social and scientific resources were deployed throughout his career is analyzed, with a view to ascertaining the moment when he broke with the tradition of biomedical research of Manguinhos and embarked on the construction of a new location where he could implement his own scientific project.

    Any therapeutic intervention carries with it the potential for benefit and harm. Generally, benefit is far more common than risk; however, risk aversion drives many of the treatment decisions made by patients and their physicians. To provide guidelines to help clinicians improve their understanding of causality and the interpretation of harm. A group of dermatologists involved in data safety monitoring boards, clinical trial investigators, and a clinical epidemiologist identified the need for practical advice on how to understand and explain causality and harm and combined to share their knowledge. An explanation of how data are collected and the environment that shapes the data seen by clinicians is presented. The article spans an overview of the regulatory environment that informs trial design for regulatory approval to a description of types of designs that inform safety and techniques, such as the rule of three, to provide guidance to clinicians in interpreting the data. Communicating the potential for harm to patients is critical. Placing the potential for rare and serious risks into perspective for the patient is as important as discussing the potential benefits of medication.

    Kieser, Jules A; Dall'alba, Gloria; Livingstone, Vicki

    2009-08-01

    This longitudinal study examines changes in understanding of dental practice among a cohort of students in the early years of a dentistry programme. In their first two professional years, we identified five distinct understandings of dental practice that we have ordered from least to most comprehensive: relieving pain or generally caring for teeth, carrying out particular dental procedures, diagnosing and treating dental problems or diseases, evaluating and responding to oral health, and finally, evaluating oral health and preventing oral disease in the community. At entry into the dental program the most common understandings among both men and women focused on dental procedures or diagnosis and treatment. The largest changes in students' responses at the end of the first and second professional years were generally in line with the emphasis of the curriculum in each of these 2 years, although prevention was not clearly featured. These data suggest that at least some students responded to the curriculum and, hence, highlight the impact of the curriculum on students' emerging understandings. We conclude that curricula can have a key role in the development of understanding of professional practice during professional programmes, although the impact of curricula is not always as expected and merits investigation.

  11. Science Teachers' Understanding and Practice of Inquiry-Based Instruction in Uganda

    Science.gov (United States)

    Ssempala, Fredrick

    High school students in Uganda perform poorly in science subjects despite the Ugandan government's efforts to train science teachers and build modern science laboratories in many public high schools. The poor performance of students in science subjects has been largely blamed on the inability by many science teachers to teach science through Inquiry-Based Instruction (IBI) to motivate the students to learn science. However, there have been no empirical studies done to establish the factors that influence science teachers' understanding and practice of IBI in Uganda. Most of the published research on IBI has been conducted in developed countries, where the prevailing contexts are very different from the contexts in developing countries such as Uganda. Additionally, few studies have explored how professional development (PD) training workshops on inquiry and nature of science (NOS) affect chemistry teachers' understanding and practice of IBI. My purpose in this multi-case exploratory qualitative study was to explore the effect of a PD workshop on inquiry and NOS on chemistry teachers' understanding and practice of IBI in Kampala city public schools in Uganda. I also explored the relationship between chemistry teachers' NOS understanding and the nature of IBI implemented in their classrooms and the internal and external factors that influence teachers' understanding and practice of IBI. I used a purposive sampling procedure to identify two schools of similar standards from which I selected eight willing chemistry teachers (four from each school) to participate in the study. Half of the teachers (those from School A) attended the PD workshop on inquiry and NOS for six days, while the control group (those from School B) did not. I collected qualitative data through semi-structured interviews, classroom observation, and document analysis. I analyzed these data by structural, conceptual and theoretical coding approach. I established that all the participating chemistry

  13. Finding a new continent versus mapping all the rivers: Recognition, ownership, and the scientific epistemological development of practicing scientists and engineers

    Verdan, Andrea Marie

    Maintaining our nation's standing as a leader of innovative and premier science and engineering research requires that those on the trajectory of these careers receive both rigorous and exceptional training. In addition to educating students in the content knowledge of these disciplines, it is also necessary to train them in the professional skills associated with being competent and conscientious scientists and engineers. In the attempts to understand the best strategies to teach these skills, research during the past few decades has shown a steadily increasing interest in improving the scientific literacy of students in science and engineering disciplines. Researchers agree that fostering this literacy---particularly with respect to understanding the nature of science, i.e., scientific epistemology---is an important component in developing students' abilities to become successful practitioners of science and engineering. This research was motivated by the need to further elucidate the formative experiences that contribute to science and engineering faculty members' personal epistemologies of science. To examine the development of these epistemologies, a phenomenographical study was designed to elucidate academic scientists' and engineers' understandings of contributions, collaborations, and credit assignment. The results and inductive, grounded-theory analysis of interviews with faculty members in the College of Engineering and Science at a large, southeastern institution revealed a model of scientific epistemological development and its possible ties to professional identity development. This model can help inform changes in mentorship and training practices to better prepare students to manage the challenges posed by being scientists and engineers in the 21st-century.

  14. The Role of Student-Advisor Interactions in Apprenticing Undergraduate Researchers into a Scientific Community of Practice

    Thiry, Heather; Laursen, Sandra L.

    2011-12-01

    Among science educators, current interest in undergraduate research (UR) is influenced both by the traditional role of the research apprenticeship in scientists' preparation and by concerns about replacing the current scientific workforce. Recent research has begun to demonstrate the range of personal, professional, and intellectual benefits for STEM students from participating in UR, yet the processes by which student-advisor interactions contribute to these benefits are little understood. We employ situated learning theory (Lave and Wenger, Situated learning: legitimate peripheral participation, Cambridge University Press, Cambridge in 1991) to examine the role of student-advisor interactions in apprenticing undergraduate researchers, particularly in terms of acculturating students to the norms, values, and professional practice of science. This qualitative study examines interviews with a diverse sample of 73 undergraduate research students from two research-extensive institutions. From these interviews, we articulate a continuum of practices that research mentors employed in three domains to support undergraduate scientists-in-training: professional socialization, intellectual support, and personal/emotional support. The needs of novice students differed from those of experienced students in each of these areas. Novice students needed clear expectations, guidelines, and orientation to their specific research project, while experienced students needed broader socialization in adopting the traits, habits, and temperament of scientific researchers. Underrepresented minority students, and to a lesser extent, women, gained confidence from their interactions with their research mentors and broadened their future career and educational possibilities. Undergraduate research at research-extensive universities exemplifies a cycle of scientific learning and practice where undergraduate researchers are mentored by graduate students and postdoctoral researchers, who are

  18. Ethics Teaching in Higher Education for Principled Reasoning: A Gateway for Reconciling Scientific Practice with Ethical Deliberation.

    Science.gov (United States)

    Aközer, Mehmet; Aközer, Emel

    2017-06-01

    This paper proposes laying the groundwork for principled moral reasoning as a seminal goal of ethics interventions in higher education, and on this basis, makes a case for educating future specialists and professionals with a foundation in philosophical ethics. Identification of such a seminal goal is warranted by (1) the progressive dissociation of scientific practice and ethical deliberation since the onset of a problematic relationship between science and ethics around the mid-19th century, and (2) the extensive mistrust of integrating ethics in science and engineering curricula beyond its "applied," "practical," or "professional" implications. Although calls by international scientific and educational bodies to strengthen ethics teaching in scientific education over the past quarter century have brought about a notion of combining competence in a certain field with competence in ethics, this is neither entrenched in the academic community, nor fleshed out as regards its core or instruments to realize it. The legitimate goals of ethics teaching in higher education, almost settled since the 1980s, can be subsumed under the proposed seminal goal, and the latter also would safeguard content and methods of ethics interventions against the intrusion of indoctrinative approaches. In this paper, derivation of the proposed seminal goal rests on an interpretation of the Kohlbergian cognitive-developmental conception of moral adulthood consisting in autonomous principled moral reasoning. This interpretation involves, based on Kant's conception of the virtuous person, integrating questions about the "good life" into the domain of principled reasoning.

  19. Affordances and Challenges of Using Argument as a Connective Discourse for Scientific Practices to Teach Climate Science

    2015-12-01

    An important goal of science education is to support development of citizens to participate in public debate and make informed decisions relevant to their lives and their worlds. The NGSS (Next Generation Science Standards) suggest engaging students in science classrooms in argumentation as a practice to help enhance the quality of evidence based decision making. In this multi-case study, we explored the use of written argumentation in eight secondary school science classrooms during a lesson on the relationship between ocean temperature and its CO2 holding capacity. All teachers of these classrooms were trained during a day long NSF funded Climate Literacy Workshop on the basic concepts of climate science, scientific practices and implementation of an activity called "It's a Gassy World". The data of the current study involved students' written arguments, teachers' written reflections on the implementation of the activity as well as field notes from the Climate Literacy Workshop. A qualitative discourse analysis of the data was used to find common themes around affordances and challenges of argument as a connective discourse for scientific practices to teach climate change. The findings show that participating in written argumentation process encouraged students to discuss their experimental design and use data interpretation for their evidences. However, the results also indicated the following challenges: a) teachers themselves need support in connecting their evidence to their claims, b) arguing a socioscientific issue creates a sensitive environment c) conceptual quality of an argument needs to be strengthen through background in courses other than science, and d) graphing skills (or lack of) can interfere with constructing scientifically accurate claims. This study has implications in effectively teaching climate change through argumentation, and thus creating opportunities for practicing authentic climate science research in K-12 classrooms.

    Full Text Available Resilience is emerging as a promising vehicle for improving management of social-ecological systems that can potentially lead to more sustainable arrangements between environmental and social spheres. Central to an understanding of how to support resilience is the need to understand social change and its links with adaptation and transformation. Our aim is to contribute to insights about and understanding of underlying social dynamics at play in social-ecological systems. We argue that longstanding indigenous practices provide opportunities for investigating processes of adaptation and transformation. We use in-depth analysis of adaptation and transformation through engagement in participatory action research, focusing on the role of cultural and social practices among the Guna indigenous peoples in Panama. Our findings reveal that cultural practices facilitating leadership development, personhood development, and social networking are critical for enabling both adaptation and transformation. Further, we argue that Guna ritual practice builds additional skills, such as critical self-reflection and creative innovation, that are important for supporting the deeper changes required by transformation.

  1. Practical epistemology: the role of peer review in organizing scientific research

    2014-01-01

    Full Text Available The article considers peer review as the main procedure for demarcating scientific knowledge from other kinds thereof, which do not meet the criteria set for research results. The authors examine the history of peer review, which has first been used in early scientific journals and then has become one of the key approaches to distributing funds for research in science foundations, such as the U.S. National Science Foundation. The article also considers the role of peer review in the legal process, wherein observance of this procedure can be seen as the main criteria, which separates scientific evidence from mere testimony. The description of the main elements of the peer review procedure is based on the "Statement of principles for scientific merit review" the summary of the results of the Global Summit on Merit Review, which brought together heads of science funding organizations from more than 50 countries. The Statement listed the following principles: expert assessment, transparency, impartiality, appropriateness, confidentiality, integrity and ethical considerations. Although these principles are seen as a way to guarantee efficient peer review one has to consider the peculiarities of a particular research area, first of all the differences between social and natural sciences. Accordingly the article gives an overview of key traits of peer review in the social sciences and humanities. The authors also consider the main procedural elements - preparation of individual reviews, consideration by panels, anonymity of reviewers. Finally the article addresses the problems of peer review such as non-transparent process, elitism in selecting reviewers, conservativeness of decisions, and possible ways of handling these problems.

    The ability to work with professionals from other disciplines to deliver collaborative, patient-centred care is considered a critical element of professional practice requiring a specific set of competencies. However, a generally accepted framework for collaborative competencies is missing, which makes consistent preparation of students and staff challenging. Some authors have argued that there is a lack of conceptual clarity of the "active ingredients" of collaboration relating to quality of care and patient outcomes, which may be at the root of the competencies issue. As part of a large Health Canada funded study focused on interprofessional education and collaborative practice, our goal was to understand the competencies for collaborative practice that are considered most relevant by health professionals working at the front line. Interview participants comprised 60 health care providers from various disciplines. Understanding and appreciating professional roles and responsibilities and communicating effectively emerged as the two perceived core competencies for patient-centred collaborative practice. For both competencies there is evidence of a link to positive patient and provider outcomes. We suggest that these two competencies should be the primary focus of student and staff education aimed at increasing collaborative practice skills.

    There is growing evidence that the spatial and temporal incidence of harmful algal blooms is increasing, posing potential risks to human health and ecosystem sustainability. Currently there are no US Federal guidelines, Water Quality Criteria and Standards, or regulations concerning the management of harmful algal blooms. Algal blooms in freshwater are predominantly cyanobacteria, some of which produce highly potent cyanotoxins. The US Congress mandated a Scientific Assessment of Freshwater Harmful Algal Blooms in the 2004 reauthorization of the Harmful Algal Blooms and Hypoxia Research and Control Act. To further the scientific understanding of freshwater harmful algal blooms, the US Environmental Protection Agency (EPA) established an interagency committee to organize the Interagency, International Symposium on Cyanobacterial Harmful Algal Blooms (ISOC-HAB). A theoretical framework to define scientific issues and a systems approach to implement the assessment and management of cyanobacterial harmful algal blooms were developed as organizing themes for the symposium. Seven major topic areas and 23 subtopics were addressed in Workgroups and platform sessions during the symposium. The primary charge given to platform presenters was to describe the state of the science in the subtopic areas, whereas the Workgroups were charged with identifying research that could be accomplished in the short- and long-term to reduce scientific uncertainties. The proceedings of the symposium, published in this monograph, are intended to inform policy determinations and the mandated Scientific Assessment by describing the scientific knowledge and areas of uncertainty concerning freshwater harmful algal blooms.

  4. The evidence-based medicine model of clinical practice: scientific teaching or belief-based preaching?

    Charles, Cathy; Gafni, Amiram; Freeman, Emily

    2011-08-01

    Evidence-based medicine (EBM) is commonly advocated as a 'gold standard' of clinical practice. A prominent definition of EBM is: the integration of best research evidence with clinical expertise and patient values. Over time, various versions of a conceptual model or framework for implementing EBM (i.e. how to practice EBM) have been developed. This paper (i) traces the evolution of the different versions of the conceptual model; (ii) tries to make explicit the underlying goals, assumptions and logic of the various versions by exploring the definitions and meaning of the components identified in each model, and the methods suggested for integrating these into clinical practice; and (iii) offers an analytic critique of the various model iterations. A literature review was undertaken to identify, summarize, and compare the content of articles and books discussing EBM as a conceptual model to guide physicians in clinical practice. Our findings suggest that the EBM model of clinical practice, as it has evolved over time, is largely belief-based, because it is lacking in empirical evidence and theoretical support. The model is not well developed and articulated in terms of defining model components, justifying their inclusion and suggesting ways to integrate these in clinical practice. These findings are significant because without a model that clearly defines what constitutes an EBM approach to clinical practice we cannot (i) consistently teach clinicians how to do it and (ii) evaluate whether it is being done. © 2010 Blackwell Publishing Ltd.

    Differences in parental feeding practices revealed across and within different ethnic/ cultural groups indicate that cultural examinations of feeding practices in understudied non-European-American populations require urgent attention. China ranks as the second largest source country for children in foreign-born U.S. households. Contrary to the stereotype of slender Asians, Chinese-American young children are at high risk for obesity but have not received sufficient attention from researchers and practitioners dealing with parental feeding practices and childhood obesity. The present study aimed to understand food-related parenting practices among Chinese immigrants in the U.S. using qualitative focus groups. Twenty-two mothers with preschool aged children participated in a discussion regarding parent-child food-related interactions and feeding practices. A thematic approach was adopted to analyze the focus group data following five stages of framework analysis. Thirteen key themes of feeding practices were identified, including 9 that are in existing feeding measures (pre-exiting practices) and 4 practices that have not been documented or emphasized in previous feeding measures (culturally-emphasized practices), including regulating healthy routines and food energy, spoon-feeding, using social comparison to pressure the child to eat, and making an effort to prepare/cook specific foods. Through the use of an emic approach and meaning-centered evidence, the complexities of parent-child interactions and unique nuances of parental feeding in this understudied population were revealed. Our findings can guide future development of culturally-appropriate measurement and inform intervention programs to promote the healthy development of Chinese-American children. PMID:25555536

    In the last decade data driven research has become a third pillar of scientific work alongside with theoretical reasoning and experiment. Greatly increased computing power and storage, together with web services and other electronic resources have facilitated a quantum leap in new research based on the analysis of great amounts of data. However, traditional scientific communication only slowly changes to new media other than an emulation of paper. This leaves many data inaccessible and, in the long run exposes valuable data to the risk of loss. To improve access to data and to create incentives for scientists to make their data accessible, a group of German data centres initiated the project "Publication and Citation of Scientific Data" (STD-DOI) which was funded by the German Science Foundation DFG for the periods 2003-2005 and 2006-2008. In this project the German National Library for Science and Technology (TIB Hannover), together with the German Research Centre for Geoscience (GFZ Potsdam), Alfred Wegener Institute for Polar and Marine Research (AWI) Bremerhaven, University of Bremen, the Max Planck Institute for Meteorology in Hamburg, and the DLR German Remote Sensing Data Center set up the first system to assign DOIs to data sets and for their publication. A prerequisite for data to be made available is a proper citation. This means that all fields mandatory for a bibliographic citation are included. In addition, a mechanism is needed that ensures that the location of the referenced data on the internet can be resolved at any time. In the past, this was a problematic issue because URLs are short-lived, many becoming invalid after only a few months. Data publication on the internet therefore needs a system of reliable pointers to a web publication to make these publications citeable. To achieve this persistence of identifiers for their conventional publications many scientific publishers use Digital Object Identifiers (DOI). The identifier is resolved through

    Scientists and educators travel great distances, spend significant time, and dedicate substantial financial resources to present at conferences. This highlights the value placed on conference interactions. Despite the importance of conferences, very little has been studied about what is learned from the presentations and how presenters can effectively achieve their goals. This essay identifies several challenges presenters face when giving conference presentations and discusses how presenters can use the tenets of scientific teaching to meet these challenges. We ask presenters the following questions: How do you engage the audience and promote learning during a presentation? How do you create an environment that is inclusive for all in attendance? How do you gather feedback from the professional community that will help to further advance your research? These questions target three broad goals that stem from the scientific teaching framework and that we propose are of great importance at conferences: learning, equity, and improvement. Using a backward design approach, we discuss how the lens of scientific teaching and the use of specific active-learning strategies can enhance presentations, improve their utility, and ensure that a presentation is broadly accessible to all audience members. © 2018 L.

  11. Some non-scientific influences on radiation protection standards and practice

    International Nuclear Information System (INIS)

    Taylor, L.S.

    1980-01-01

    The influence of philosophy, politics, the media, morality, laws and economics on standards of radiation protection are discussed. While it is known that the dose-effect relationship for low-LET radiations is not linear over the whole dose range, it has been assumed to be linear in the interest of caution. This assumption has resulted in widespread controversy concerning radioprotection standards. Possible corrective actions include better communication within the scientific community and with the general public and much broader education of and dissemination of information to the public.

  14. Enacting understanding of inclusion in complex contexts: Classroom practices of South African teachers

    2015-08-01

    Full Text Available While the practice of inclusive education has recently been widely embraced as an ideal model for education, the acceptance of inclusive education practices has not translated into reality in most mainstream classrooms. Despite the fact that education policies in South Africa stipulate that all learners should be provided with the opportunities to participate as far as possible in all classroom activities, the implementation of inclusive education is still hampered by a combination of a lack of resources and the attitudes and actions of the teachers in the classroom. The main purpose of this paper was to develop a deeper understanding of a group of South African teachers' personal understanding about barriers to learning and how their understanding relates to their consequent actions to implement inclusive education in their classrooms. A qualitative research approach placed within a cultural-historical and bio-ecological theoretical framework was used. The findings, in this paper, indicate that the way in which teachers understand a diversity of learning needs is based on the training that they initially received as teachers, which focused on a deficit, individualised approach to barriers to learning and development, as well as contextual challenges, and that both have direct and substantial effects on teachers' classroom practices. As a result, they engage in practices in their classrooms that are less inclusive, by creating dual learning opportunities that are not sufficiently made available for everyone, with the result that every learner is not able to participate fully as an accepted member of their peer group in all classroom activities.

    The performance of a pathological post-mortem examination is quite different from on carried out for medico-legal reasons. One is directed by a search fo scientific knowledge, the other by justice. Even though they have much in common, there are clear differences in the physician's practice and approach.Medico-legal considerations introduce technical modifications, including a more scrupulous external examination, giving the forensic expert an advantage not available to the pathologist. In addition, the forensic expert is often working under pressure, as he is obliged avoid any professional errors and may have to work quickly under difficult conditions.

    Stewart, Janice; Stansfield, Katherine; Tapp, Dianne

    2004-10-01

    The purpose of the study was to enable nurse managers to identify strategies to support and enhance autonomous practice based on clinical nurses' understanding of autonomy. Findings from an organizational work-life satisfaction survey led a nursing management team to question how clinical nurses understand autonomy. The nursing literature offers inconsistent definitions of autonomy and interchangeable use of related concepts. Twelve focus groups involving 43 nurses working in cardiovascular service units discussed instances of satisfaction and dissatisfaction with autonomy in their clinical practice and work life. Verbatim transcripts of group discussions were interpreted by a research team to identify salient examples and descriptions of autonomy. Nurses described autonomy as their ability to accomplish patient care goals in a timely manner by using their knowledge and skills to understand and contribute to the overall plan of care; assess patient needs and conditions; effectively communicate concerns and priorities regarding patient care; and access and coordinate the resources of the multidisciplinary team. These findings challenge assumptions about autonomy as independent decision making and practice. They highlight nurses' contributions to patient care goals through knowledge of how to get things done within hospital systems and through interdisciplinary coordination and collaboration.

    2012-02-03

    PURPOSE: To examine emergency nurses\\' current practices and understanding of family presence during CPR in the emergency department, Cork University Hospital, Republic of Ireland. METHOD: A quantitative descriptive design was used in the study. A questionnaire developed by ENA was distributed to emergency nurses working in a level I trauma emergency department at Cork University Hospital. The total sample number was 90, including all emergency nurses with at least 6 months\\' emergency nursing experience. RESULTS: Emergency nurses often took families to the bedside during resuscitation efforts (58.9%) or would do so if the opportunity arose (17.8%). A high percentage (74.4%) of respondents would prefer a written policy allowing the option of family presence during CPR. The most significant barrier to family witnessed resuscitation (FWR) was conflicts occurring within the emergency team. The most significant facilitator to FWR was a greater understanding of health care professionals on the benefits of FWR to patients and families, indicating the need for educational development. CONCLUSION: The findings of the study and previously published studies indicate the need for development of written polices and guidelines on the practice to meet the needs of patients, families, and staff by providing consistent, safe, and caring practices for all involved in the resuscitation process. Recommendations of the study include the development of a written policy and an educational programme on the safe implementation and practices of FWR.

    Conventional sports training emphasizes adequate training of muscle fibres, of cardiovascular conditioning and/or neuromuscular coordination. Most sports-associated overload injuries however occur within elements of the body wide fascial net, which are then loaded beyond their prepared capacity. This tensional network of fibrous tissues includes dense sheets such as muscle envelopes, aponeuroses, as well as specific local adaptations, such as ligaments or tendons. Fibroblasts continually but slowly adapt the morphology of these tissues to repeatedly applied challenging loading stimulations. Principles of a fascia oriented training approach are introduced. These include utilization of elastic recoil, preparatory counter movement, slow and dynamic stretching, as well as rehydration practices and proprioceptive refinement. Such training should be practiced once or twice a week in order to yield in a more resilient fascial body suit within a time frame of 6-24 months. Some practical examples of fascia oriented exercises are presented. Copyright © 2012 Elsevier Ltd. All rights reserved.

  1. Towards an ecology of eating disorders: creating sustainability through the integration of scientific research and clinical practice.

    2010-01-01

    The field of eating disorders is currently at a crossroads and faces important challenges of sustainability. These challenges include problems with the current diagnostic classification of eating disorders and the divide between scientific research and clinical practice. If not addressed, there is a danger that the field will fail to evolve adaptively, risking increased stagnation and reduced relevance. To meet these challenges, researchers and clinicians must work toward a more holistic ecology of eating disorders based on the interaction of theory, research and practice. The present paper proposes six steps towards increased sustainability based on developing clinically relevant diagnosis, using systematic quality assurance, expanding the scope of treatment research and the definition of evidence, promoting therapist development, as well as stimulating diversity and discourse. If we rise to the occasion and face these challenges, then we will be better equipped to meet the evolving needs of clinicians, researchers, and most importantly patients.

    This final report for the Swiss Federal Office of Energy (SFOE) takes a look at the findings of a study made by the University of Zurich, Switzerland, on socio-scientific aspects of energy use. Basic socio-psychological mechanisms are examined on which energy policy instruments can be based. Basic mechanisms are discussed such as enforced behaviour, non-enforced action, habitual acts and action taken on the basis of heuristics and rules-of-thumb. The second part of the paper looks at examples of the use of these principles, discussing, amongst other things, cost-benefit and moral reasoning, habits, mental accounting and boomerang effects. Finally the analyses are summarised and further research needed as a result of these analyses is noted.

    2013-03-01

    Chinese and contemporary Western medical practices evolved on different cultures and historical contexts and, therefore, their medical knowledge represents this cultural divergence. Computerization of traditional Chinese medicine (TCM) is being used to promote the integrative medicine to manage, process and integrate the knowledge related to TCM anatomy, physiology, semiology, pathophysiology, and therapy. We proposed the development of the SuiteTCM software, a collection of integrated computational models mainly derived from epidemiology and statistical sciences for computerization of Chinese medicine scientific research and clinical practice in all levels of prevention. The software includes components for data management (DataTCM), simulation of cases (SimTCM), analyses and validation of datasets (SciTCM), clinical examination and pattern differentiation (DiagTCM, TongueTCM, and PulseTCM), intervention selection (AcuTCM, HerbsTCM, and DietTCM), management of medical records (ProntTCM), epidemiologic investigation of sampled data (ResearchTCM), and medical education, training, and assessment (StudentTCM). The SuiteTCM project is expected to contribute to the ongoing development of integrative medicine and the applicability of TCM in worldwide scientific research and health care. The SuiteTCM 1.0 runs on Windows XP or later and is freely available for download as an executable application.

    Full Text Available Introduction: 80 % of adults experience back pain at least once in their life. Back pain is the third leading cause of consultation in the emergency room, the fourth in general practice, the second of disability pension and the first job relocation. Objective: To compare the criteria that guide decision making of a group of physiotherapists in Bogota Colombia for the management of chronic nonspecific low back pain management criteria contained in the guide COST B13 (European Guidelines For The Management Of Chronic Non- specific Low Back Pain, 2004. Material and methods: This was a descriptive study, for which clinical practice guideline COST B13 for the management of chronic nonspecific low back pain through the AGREE tool is selected and a survey was applied to 50 physiotherapists through a convenience sample with to compare the clinical practices that are performed with the recommendations given guidance. Results: 56 % of respondents had some type of training for the management of chronic nonspecific low back pain (DLCI. 94 % of patients with DLCI served range in age from 40 to 59, with female predominance. In 80 % of respondents stated that physiotherapists diagnostic help with counting for the management of patients is the radiological image. 80 % of physiotherapists evaluated variable lumbar pain experienced by the patient and 54 % stance. Other aspects were reported in lower percentage. In the treatment of DLCI, physiotherapists reported use of stretching in 80 % of cases, the superficial thermotherapy in 70 % and isometric muscle strength in 70 %, all with favorable results.Conclusion: There are differences between clinical practice of physiotherapists and guidelines contained in the recommendations of the guide in the cost DLCI B13. Mainly in the processes of physiotherapy assessment of the surveyed population as they are often focused on observation and not always in the rigorous measurement, which makes it difficult to establish

    The proper usage of the anatomical terminology is of paramount importance to all medical professionals. Although a multitude of studies have been devoted to issues associated with the use and application of the recent version of the anatomical terminology in both theoretical medicine and clinical practice, there are still many unresolved problems such as confusing terms, inconsistencies, and errors, including grammar and spelling mistakes. The aim of this article is to describe the current situation of the anatomical terminology and its usage in practice, as well as explain why it is so important to use precise, appropriate, and valid anatomical terms during the everyday communication among physicians from all medical branches. In this review, we discuss some confusing, obsolete, and erroneous terms that are still commonly used by many clinicians, and surgeons in particular, during the process of diagnosis and treatment. The use of these ambiguous, erroneous, and obsolete terms enhances the risk of miscommunication. We also provide some edifying examples from everyday clinical practice.

  10. Concept Communication and Interpretation of Illness: A Holistic Model of Understanding in Nursing Practice.

    Science.gov (United States)

    Nordby, Halvor

    To ensure patient communication in nursing, certain conditions must be met that enable successful exchange of beliefs, thoughts, and other mental states. The conditions that have received most attention in the nursing literature are derived from general communication theories, psychology, and ethical frameworks of interpretation. This article focuses on a condition more directly related to an influential coherence model of concept possession from recent philosophy of mind and language. The basic ideas in this model are (i) that the primary source of understanding of illness experiences is communicative acts that express concepts of illness, and (ii) that the key to understanding patients' concepts of illness is to understand how they depend on patients' lifeworlds. The article argues that (i) and (ii) are especially relevant in caring practice since it has been extensively documented that patients' perspectives on disease and illness are shaped by their subjective horizons. According to coherentism, nurses need to focus holistically on patients' horizons in order to understand the meaning of patients' expressions of meaning. Furthermore, the coherence model implies that fundamental aims of understanding can be achieved only if nurses recognize the interdependence of patients' beliefs and experiences of ill health. The article uses case studies to elucidate how the holistic implications of coherentism can be used as conceptual tools in nursing.

    2014-02-01

    While empirical evidence continues to show that people living in low socio-economic status neighbourhoods are less likely to engage in health-enhancing behaviour, our understanding of why this is so remains less than clear. We suggest that two changes could take place to move from description to understanding in this field; (i) a move away from the established concept of individual health behaviour to a contextualised understanding of health practices; and (ii) a switch from focusing on health inequalities in outcomes to health inequities in conditions. We apply Pierre Bourdieu's theory on capital interaction but find it insufficient with regard to the role of agency for structural change. We therefore introduce Amartya Sen's capability approach as a useful link between capital interaction theory and action to reduce social inequities in health-related practices. Sen's capability theory also elucidates the importance of discussing unequal chances in terms of inequity, rather than inequality, in order to underscore the moral nature of inequalities. We draw on the discussion in social geography on environmental injustice, which also underscores the moral nature of the spatial distribution of opportunities. The article ends by applying this approach to the 'Interdisciplinary study of inequalities in smoking' framework. © 2013 The Authors.

  13. Identifying children who may be cognitively gifted: the gap between practical demands and scientific supply

    Directory of Open Access Journals (Sweden)

    KLAUS D. KUBINGER

    2008-06-01

    Full Text Available When it comes to high cognitive ability assessment, traditional “IQ-diagnosis” has not proven to be particularly helpful. Psychological assessment aimed at promoting the development of gifted individuals requires a scientifically based theoretical model that identifies which cognitive strengths are necessary and which weaknesses can be compensated, and that takes the moderating effects of personality and environment into account when describing the interplay between ability and achievement. While such models – including the one described in the following paper – do exist, they currently lack an adequate theoretical foundation or at least a convincing empirical validation. Science still stands before the challenge of offering appropriate psychodiagnostic instruments to measure model components while fulfilling practitioners’ requirements. The following work describes a prototypic example of how such requirements might be met for ability testing. Yet in terms of personality and environmental variables, particularly caregiving, currently available methods are wholly unsuitable for meeting intended goals. Systematic behavioral observation offers a possible solution. Its validity, objectivity, comprehensiveness and efficiency in terms of high ability testing – as well as that of interview guides – must, however, be further explored.

    2017-07-01

    There has been limited information about epidemiology and clinical practice of acute respiratory distress syndrome (ARDS) in Japan. An invitation letter to the web-based survey was mailed to all 871 board certified hospitals of the Japanese Respiratory Society. The questionnaires were designed to collect data on epidemiology and clinical practice of ARDS, including diagnostic measures and therapeutics. Within 4 months of the survey period, valid responses were obtained from 296 (34%) hospitals. The incidence of ARDS was estimated to be 3.13 cases/100 hospital beds or 1.91 cases/ICU bed per year. The most frequent underlying disease was pneumonia (34%), followed by sepsis (29%). In hospitals with fewer ICU beds, pulmonologists tended to be in charge of management of ARDS patients. Routine diagnostic measures included computed tomography of the chest (69.6% of the hospitals) and Swan-Ganz catheterization was rarely performed for diagnosis. In 87.4% of the hospitals, non-invasive ventilation was applied to management of ARDS patients, especially those with mild disease. Prone positioning and extracorporeal membrane oxygenation (ECMO) for ARDS patients was more widely adopted in hospitals with larger numbers of ICU beds and intensivists. In 58.2% of the responding hospitals, corticosteroid was considered as a treatment option for ARDS, among which pulse therapy was routinely introduced to ARDS patients in 35.4%. The incidence of ARDS in Japan was estimated to be lower than that in the recent international study. The scale and equipment of hospitals and the number of intensivists might influence clinical practice of ARDS. Copyright © 2017 The Japanese Respiratory Society. Published by Elsevier B.V.

    2017-11-01

    Socioeconomic inequalities in health persist despite major investments in illness prevention campaigns and universal healthcare systems. In this context, the increased risks of chronic diseases of specific sub-groups of vulnerable populations should be further investigated. The objective of this qualitative study is to examine the interaction between socioeconomic status (SES) and body weight in order to understand underprivileged women's increased vulnerability to chronic diseases after menopause. By drawing specifically on Pierre Bourdieu's sociocultural theory of practice, 20 semi-structured interviews were conducted from May to December of 2013 to investigate the health practices of clinically overweight, postmenopausal women living an underprivileged life in Canada. Findings emphasise that poor life conditions undermine personal investment in preventive health and weight loss, showing the importance for policy makers to bring stronger consideration on upstream determinants of health. © 2017 Foundation for the Sociology of Health & Illness.

    Contemporary data about the use of magnetotherapy, ultrasound and magnetolaser therapy in resonance energy ranges are presented in this book. Practical methodics of simultaneous and combined use of these physical factors in different branches of clinical medicine (neurology, cardiology, gastroenterology and others) are described. General idea of biological rhythms is given and it is considered as a background of living systems development. Biorhythms are used for determination of 'biological resonance', the optimum correlation between vibrations of the organism and external ones. In such a way the best results of treatment are achieved. Modern principles of the sensitive zone choice, bases of biorhythmic and resonance phenomena are presented. Practical uses of them became more and more important in physiotherapy and acupuncture. Human biological rhythms are taken into consideration during bioresonance treatment. Features of each treatment method are described. Reactions of different organism systems (nervous, hearth and vessel, bone, respiratory systems, internal secretion) on magnetic field influence, obtained treatment effects of magnetotherapy and possible mistakes in treatment are discussed. Special advices on the use of ultrasound therapy and magnetotherapy are given. The most part of magneto-laser-ultrasound therapy uses refers to the new generation of series 'MIT' and 'MIT-11' apparat which combine all three treatment factors

    Research has characterized advanced kagome fiber optics for their use in laser ignition systems. In comparison to past fibers used in laser ignition, these fibers have the important advantage of being relatively bend-insensitivity, so that they can be bent and coiled without degradation of output energy or beam quality. The results are very promising for practical systems. For pulse durations of ~12 ns, the fibers could deliver >~10 mJ pulses before damage onset. A study of pulse duration showed that by using longer pulse duration (~20 – 30 ns), it is possible to carry even higher pulse energy (by factor of ~2-3) which also provides future opportunities to implement longer duration sources. Beam quality measurements showed nearly single-mode output from the kagome fibers (i.e. M2 close to 1) which is the optimum possible value and, combined with their high pulse energy, shows the suitability of the fibers for laser ignition. Research has also demonstrated laser ignition of an engine including reliable (100%) ignition of a single-cylinder gasoline engine using the laser ignition system with bent and coiled kagome fiber. The COV of IMEP was <2% which is favorable for stable engine operation. These research results, along with the continued reduction in cost of laser sources, support our commercial development of practical laser ignition systems.

    2008-01-01

    Full Text Available In our attempts to track changes in geological practice over time and to isolate the source of these changes, we have found that they are largely connected with the germination of new geologic subdisciplines. We use keyword and title data from articles in 68 geology journals to track the changes in influence of each subdiscipline on geology over all. Geological research has shifted emphasis over the study period, moving away from economic geology and petroleum geology, towards physics- and chemistry-based topics. The Apollo lunar landings had as much influence on the topics and practice of geological research as the much-cited plate-tectonics revolution. These results reflect the barely-tangible effects of the changes in vocabulary and habit of thought that have pervaded the substance of geology. Geological literature has increased in volume and specialization, resulting in a highly fragmentary literature. However, we infer that "big science," characterized by large amounts of funding, collaboration, and large logistical investments, makes use of this specialization and turns "twigging" into a phenomenon that enhances, rather than inhibits, the enterprise of research.

    Functioning program infrastructure is necessary for achieving public health outcomes. It is what supports program capacity, implementation, and sustainability. The public health program infrastructure model presented in this article is grounded in data from a broader evaluation of 18 state tobacco control programs and previous work. The newly developed Component Model of Infrastructure (CMI) addresses the limitations of a previous model and contains 5 core components (multilevel leadership, managed resources, engaged data, responsive plans and planning, networked partnerships) and 3 supporting components (strategic understanding, operations, contextual influences). The CMI is a practical, implementation-focused model applicable across public health programs, enabling linkages to capacity, sustainability, and outcome measurement. PMID:24922125

    Magnetic resonance imaging (MRI) is a sensitive diagnostic modality for the detection of inflammatory changes in peripheral joints. Nevertheless, the widespread clinical use of MRI in assessing patients with early rheumatoid arthritis is still hampered by the technical complexity and higher cost of MRI compared with conventional radiography. This overview summarizes the results of recent research and gives practical tips on how to perform MRI of the hands. The authors present an MR protocol for hand imaging, discuss the pros and cons of low-field MR scanners, and outline pitfalls and artifacts. The MRI changes associated with rheumatoid arthritis such as synovitis, tenosynovitis, erosions, and bone marrow edema are described including their prognostic significance. The proven facts on the validation and grading of MR changes in rheumatoid arthritis are summarized. Finally, the role of MRI in the differential diagnosis of arthritis is critically discussed.

    Connolly, Joseph W.

    The bicycle is a common, yet unique mechanical contraption in our world. In spite of this, the bike's physical and mechanical principles are understood by a select few. You do not have to be a genius to join this small group of people who understand the physics of cycling. This is your guide to fundamental principles (such as Newton's laws) and the book provides intuitive, basic explanations for the bicycle's behaviour. Each concept is introduced and illustrated with simple, everyday examples. Although cycling is viewed by most as a fun activity, and almost everyone acquires the basic skills at a young age, few understand the laws of nature that give magic to the ride. This is a closer look at some of these fun, exhilarating, and magical aspects of cycling. In the reading, you will also understand other physical principles such as motion, force, energy, power, heat, and temperature.

    This scientific statement provides an interprofessional, comprehensive review of evidence and recommendations for indications, duration, and implementation of continuous electro cardiographic monitoring of hospitalized patients. Since the original practice standards were published in 2004, new issues have emerged that need to be addressed: overuse of arrhythmia monitoring among a variety of patient populations, appropriate use of ischemia and QT-interval monitoring among select populations, alarm management, and documentation in electronic health records. Authors were commissioned by the American Heart Association and included experts from general cardiology, electrophysiology (adult and pediatric), and interventional cardiology, as well as a hospitalist and experts in alarm management. Strict adherence to the American Heart Association conflict of interest policy was maintained throughout the consensus process. Authors were assigned topics relevant to their areas of expertise, reviewed the literature with an emphasis on publications since the prior practice standards, and drafted recommendations on indications and duration for electrocardiographic monitoring in accordance with the American Heart Association Level of Evidence grading algorithm that was in place at the time of commissioning. The comprehensive document is grouped into 5 sections: (1) Overview of Arrhythmia, Ischemia, and QTc Monitoring; (2) Recommendations for Indication and Duration of Electrocardiographic Monitoring presented by patient population; (3) Organizational Aspects: Alarm Management, Education of Staff, and Documentation; (4) Implementation of Practice Standards; and (5) Call for Research. Many of the recommendations are based on limited data, so authors conclude with specific questions for further research. © 2017 American Heart Association, Inc.

    Carvalho, Joana Christina; Mestrinho, Heliana Dantas

    2014-01-01

    Over the last decade, there has been growing interest in diagnosing non-cavitated lesions in epidemiological studies involving large numbers of preschool children, schoolchildren and young adults. In this context, assessment of lesions characteristics indicating whether or not there is ongoing mineral loss is also considered relevant. The reasoning sustained by these studies is that diagnosis of the caries process limited to the cavitated level is no longer in accordance with current state-of-the-art knowledge in cariology. This paper highlights one topic of the lecture entitled "Caries Process: Evolving Evidence and Understanding," presented at the 18th Congress of the Brazilian Association for Oral Health Promotion (Associação Brasileira de Odontologia de Promoção de Saúde - ABOPREV) in April 2013. In the framework of epidemiological studies, the interest in diagnosing active and inactive non-cavitated lesions was elucidated. However, relevant questions associated with the diagnosis of non-cavitated lesions that might raise concerns among researchers and health administrators were not addressed. The present paper aims to bring these questions into discussion. The contribution of this discussion in terms of developing the understanding of caries decline is analyzed by using data from a caries trends study of Brazilian preschool children residing in the Federal District of Brazil as an example. The inclusion of active and inactive non-cavitated lesions in the diagnosis of the caries process allowed us to demonstrate that, in Brazilian 1- to 5-year-old children, caries prevalence decreased significantly from 1996 to 2006, simultaneously with a reduction in the rate of caries progression.

  9. Understanding as Integration of Heterogeneous Representations

    Martínez, Sergio F.

    2014-03-01

    The search for understanding is a major aim of science. Traditionally, understanding has been undervalued in the philosophy of science because of its psychological underpinnings; nowadays, however, it is widely recognized that epistemology cannot be divorced from psychology as sharp as traditional epistemology required. This eliminates the main obstacle to give scientific understanding due attention in philosophy of science. My aim in this paper is to describe an account of scientific understanding as an emergent feature of our mastering of different (causal) explanatory frameworks that takes place through the mastering of scientific practices. Different practices lead to different kinds of representations. Such representations are often heterogeneous. The integration of such representations constitute understanding.

  14. Understanding the divide between the theory and practice of organisational change

    Directory of Open Access Journals (Sweden)

    Julien Pollack

    2015-07-01

    Full Text Available This paper reviews the different ways that academics and practitioners write about and discuss change management, to develop an understanding of whether there is a divide between the theory and practice of change management. This research used scientometric research techniques to compare three corpora: one based on the most cited research in the general management literature on change management; one based on the most cited research in specialist change management journals; and one based on interviews with practising change managers. It was found that the general management literature emphasised an abstract understanding of knowledge management and the learning organisation, while the change management literature focused more on issues associated with value, culture and social identity. The practitioners emphasised issues at the individual, project and team levels, the need for the effective use of targeted communication to achieve organisational change objectives, and the value of rapidly identifying key drivers in a new context. This research found significant differences between these three corpora, which lends support to other researchers’ claims of a divide between theory and practice in change management.

    2011-07-01

    Full Text Available Popular culture abounds with ill-conceived notions about Earth’s processes.  Movies, books, music, television and even video games frequently misrepresent fundamental scientific principles, warping viewers’ perceptions of the world around them.  First year geoscience students are not immune to pop culture’s portrayal of earth science and the misconceptions they bring to Geology 101 cloud their ability to differentiate between fact and fiction.  Working within an action research context, a semester-long assessment was designed with the intent to highlight and subsequently challenge students’ misconceptions using examples of “bad geoscience” from pop culture.  Students were required to practice and refine generic skills within this context.  This project succeeded in engaging students, but requires refinement to become more effective in enhancing their geoscience literacy.

    2011-09-01

    Full Text Available Several studies on the treatment of musculoskeletal diseases with physiotherapy and clinical experiences on the basis of a method called Rééducation Posturale Globale (RPG, have highlighted the usefulness of this treatment. Although such treatment technique is commonly used in physical therapy practice, only few studies support its therapeutic effectiveness. Objective: To search the literature for evidence of RPG effectiveness, in order to identify the most appropriate therapeutic contexts for its use. Methods: A review of the literature through the following databases: PubMed, Embase, Cinahl, Pedro, and Medscape. The keywords used for the search in the databases are: Rééducation Posturale Globale, Souchard, Posture, and Manual Therapy. The following clinical studies were selected: randomized controlled studies, non-randomized controlled studies, observation studies, and case reports, in English, Spanish, Portuguese, and Italian. Results: Out of 18 studies found, 9 were analyzed: 2 randomized controlled studies, 2 non-randomized controlled studies, 3 non-controlled studies, and 2 case reports. Conclusions: The RPG method has been shown to be an effective treatment technique for musculoskeletal diseases, in particular for ankylosing spondylitis, acute and chronic low back pain, and lumbar discherniation. Although the scarcity of rigorous experimental trials on a large scale does not allow the drawing of undisputable conclusions, the results gathered up to now are an encouragement to carry on research in the field of conservative treatment.

    Earth Camp is a NASA-funded program that gives students and teachers opportunities to explore local, regional, and global earth change through a combination of hands-on investigations and the use of satellite images. Each summer, 20 middle school and 20 high school students participate in a two-week leadership program investigating contemporary issues (e.g., changes in river sheds, water quality, and land use management) through hands-on investigations, analyzing remote sensing data, and working with experts. Each year, 20 teachers participate in a year-long professional development program that includes monthly workshops, field investigations on Mt. Lemmon in Tucson, Arizona, and a week-long summer design workshop. Teachers conduct investigations of authentic questions using satellite images and create posters to present results of their study of earth change. In addition, teachers design lesson plans to expand their students' ability to investigate earth change with 21st Century tools. Lessons can be used as classroom exercises or for after-school club programs. Independent evaluation has been an integral part of program development and delivery for all three audiences, enabling the program staff and participants to reflect on and continually improve their practice and learning over the three-year period.

    To describe the process by which various forms of evidence are discussed, valued, and interpreted within the process of developing evidence-based clinical practice guidelines and, in so doing, to develop a method for such studies. An observational study. Two guideline development groups were observed by a nonparticipant observer. The 21 meetings were recorded, transcribed, and analyzed using grounded theory and frame analysis. Qualitative analysis was complemented with descriptive statistics. The groups organized their discussion around four domains--'science', 'practice', politics', and 'process'--and used boundary work to mediate between these domains. Both groups spent most time discussing 'science', followed by 'practice' or its relation with 'science'. Our analysis offers an innovative, replicable method of analysis of guideline development that permits the identification of the proportions and interrelations between knowledge domains deployed by guideline groups. This analysis also suggests that the participation hierarchy observed here and by others might be an effect of the imbalanced use of knowledge domains in the construction of clinical guidance. This constitutes an important framework to understand the interplay of participants and knowledge in guideline development.

    Ruggiano, Nicole; Lukic, Andreja; Blowers, Anita; Doerner, Jill

    The population of aging prisoners has increased significantly over the past several decades, resulting in concerns about the criminal justice system's ability to address the needs of prisoners and parolees with chronic health conditions. This is troubling, given the health disparities among incarcerated populations. Health self-management has become a strategy within the community-based health care industry to improve health services and outcomes while reducing health care costs for nonincarcerated individuals with chronic conditions. However, to date little research has focused on the practice or promotion of health self-management among current and former incarcerated populations. This article highlights current understandings about chronic health self-management among older prisoners and parolees, with an emphasis on the potential benefits and current challenges in promoting their health self-management practices. Finally, specific recommendations are made for promoting health self-management for these populations through social work practice, policy advocacy, and research to achieve goals in improving health outcomes and reducing healthcare costs.

    2016-01-01

    Providing many unique MATLAB codes and functions throughout, this book covers the basics of Magnetic Resonance Imaging (MRI), leading to an in-depth understanding of the concepts and tools required for analysis and interpretation of Phase Contrast MR Angiography (PC-MRA). The concept of PC-MRA is often difficult, but essential for practicing engineers and scientists working in MR related areas. The concepts are better understood by uniquely combining the physical principles of fluid flow and MR imaging, laid out by modeling the theory and applications using a commonly used software tool MATLAB®. The book starts with a detailed theory of PC-MRA followed by a description of various image processing methods, including detailed MATLAB codes used for their implementation. The flow concepts in the context of MR imaging are explained using MATLAB based simulations.

    1998-01-01

    Full text: Last year, I presented a case study about the development of BNFL's advertising strategy and the challenges which we overcame since its launch in 1995. The case study this year will follow the progress of the strategy's second phase. It will begin by reiterating the role of advertising in the communications mix and the distinct part we believe it plays in building and retaining a strong corporate reputation amongst influential audiences within the UK. Our advertising to date has aimed to define BNFL's role in the nuclear sector and so detach the company from the contentious debate which surrounds the nuclear industry in general. The case study will briefly summarise how effective we have been in achieving this objective through the first phase of television and press advertising. The presentation will concentrate, in particular, on the development of the second phase which has involved the production of a new television advertisement and a press and poster advertisement. Having introduced the key characteristics of the company to the UK population during the first phase through describing key scientific achievements, phase two concentrates on BNFL's core activity - recycling nuclear fuel. The presentation will outline the various development phases including concept research, our tough negotiations with the UK's advertising regulatory bodies (the Broadcast Advertising Clearance Centre (BACC) and the Independent Television Commission (ITC) through to final production, testing and media scheduling. Generating positive attribution amongst the UK population is obviously the key success indicator. Equally, we believe that it is imperative to share such communications activity with another key stakeholder - our own employees. The case study will outline the phase of internal negotiations and substantiation through to the methods we adopted to ensure that employees saw the television advertisement before the UK population at large. The campaign was launched on

    In order to minimize adverse health effects and increase the benefits of physical activity, it is important to systematize indoor air quality study in environments used for physical exercise and sports. To investigate and analyze the scientific production related to indoor air quality of environments used for physical exercise and sports practice through a bibliometric analysis. The databases Scielo, Science Direct, Scopus, Lilacs, Medline via Pubmed, and SportDiscus were searched from their inception to March 2016. Bibliometric analysis was performed for authors, institutions, countries, and collaborative networks, in relation to publication year, theme, citation network, funding agency, and analysis of titles and keywords of publications. Country, area, and impact factor of the journals were analyzed. Of 1281 studies screened, 34 satisfied the inclusion criteria. The first publication occurred in 1975. An increase in publications was observed in the last 15 years. Most of the studies were performed by researchers in the USA, followed by Portugal and Italy. Seventeen different scientific journals have published studies on the subject, and most are in the area of Environmental Sciences. It was noted that the categories of author keywords associated with "Pollutants," "Sport Environment," and "Physical Exercise" were the most commonly used in most studies. A total of 68% of the studies had at least one funding agency, and 81% of studies published in the last decade had funding. Our results demonstrate that there is recent exponential growth, driven in the last decade by researchers in environmental science from European institutions. Copyright © 2017 Elsevier Ltd.

    arise in the practice of rural EM. Ultimately, the ability to manage the pressures of rural EM leads physicians to either thrive in or leave rural EM practice. The theoretical model provides a more complex view of the realities of rural EM care than has been previously described. It identifies factors that enable and hinder rural EM physicians in their practice, and provides an understanding of the strategies they employ to navigate challenges. Some elements of the theoretical model have been previously identified. For example, existing work has found that many rural physicians experience fear and anxiety in their practice. The challenges posed by the variation in rural practice environments have also been previously identified as an important influence. Other elements of the theoretical model, and the common need for practitioners to creatively respond to barriers arising from the healthcare system's inability to respond to local needs, have not been previously identified. This work finds these factors to be a common experience for participants, and as such, more widespread recognition of the importance of these factors could lead to system improvements. Future research is needed to test the hypotheses proposed in this study and explore the generalizability of the findings.

    2015-03-01

    Full Text Available This article concerns itself with the development of a missional ecclesiology and the practices that may accept the challenge of conducting pastoral ministry in the context of South African, middleclass congregations adapting to a rapidly changing, post-apartheid environment. Some practical theological perspectives on pastoral counselling are investigated, whilst Narrative Therapy is explored as an emerging theory of deconstruction to enable the facilitating of congregational change towards a missional understanding of church life in local communities. Subsequently, the theological paradigm of missional ecclesiology is investigated before drawing the broad lines of a theory for pastoral ministry within missional ecclesiology.Intradisciplinary and/or interdisciplinary implications: In this article, a missional base theory is proposed for pastoral counselling, consisting of interdisciplinary insights gained from the fields of Missiology, Practical Theology, Narrative Therapy and Cognitive Behaviour Therapy. The implications of this proposal for the development of a missional pastoral theory focus on the following three aspects:� re-establishing pastoral identity: exploring Christ� pastoral development: intentional faith formation� pastoral ministry: enabling Christ-centred lives.In such a missional pastoral theory four practices should be operationalised: first of all, a cognitive approach to increasing knowledge of the biblical narrative is necessary. This provides the hermeneutical skills necessary to enable people to internalise the biblical ethics and character traits ascribed to the Christian life. Secondly, a pastoral theory needs to pay close attention to development of emotional intelligence. Thirdly, this should be done in the context of small groups, where the focus falls on the personality development of members. Finally, missional pastoral theory should also include the acquisition of life coaching skills, where leaders can be

    We report experimentally and theoretically the behavior of freestanding graphene subjected to bombardment of energetic ions, investigating the capability of large-scale patterning of freestanding graphene with nanometer sized features by focused ion beam technology. A precise control over the He+ and Ga+ irradiation offered by focused ion beam techniques enables investigating the interaction of the energetic particles and graphene suspended with no support and allows determining sputter yields of the 2D lattice. We found a strong dependency of the 2D sputter yield on the species and kinetic energy of the incident ion beams. Freestanding graphene shows material semi-transparency to He+ at high energies (10-30 keV) allowing the passage of >97% He+ particles without creating destructive lattice vacancy. Large Ga+ ions (5-30 keV), in contrast, collide far more often with the graphene lattice to impart a significantly higher sputter yield of ~50%. Binary collision theory applied to monolayer and few-layer graphene can successfully elucidate this collision mechanism, in great agreement with experiments. Raman spectroscopy analysis corroborates the passage of a large fraction of He+ ions across graphene without much damaging the lattice whereas several colliding ions create single vacancy defects. Physical understanding of the interaction between energetic particles and suspended graphene can practically lead to reproducible and efficient pattern generation of unprecedentedly small features on 2D materials by design, manifested by our perforation of sub-5 nm pore arrays. This capability of nanometer-scale precision patterning of freestanding 2D lattices shows the practical applicability of focused ion beam technology to 2D material processing for device fabrication and integration.We report experimentally and theoretically the behavior of freestanding graphene subjected to bombardment of energetic ions, investigating the capability of large-scale patterning of

    Hvidsten, Connie J.

    Connie J. Hvidsten September 2016 Education Secondary Science Teachers Making Sense of Model-Based Classroom Instruction: Understanding the Learning and Learning Pathways Teachers Describe as Supporting Changes in Teaching Practice This dissertation consists of three papers analyzing writings and interviews of experienced secondary science teachers during and after a two-year professional development (PD) program focused on model-based reasoning (MBR). MBR is an approach to science instruction that provides opportunities for students to use conceptual models to make sense of natural phenomena in ways that are similar to the use of models within the scientific community. The aim of this research is to better understand the learning and learning pathways teachers identified as valuable in supporting changes in their teaching practice. To accomplish this aim, the papers analyze the ways teachers 1) ascribe their learning to various aspects of the program, 2) describe what they learned, and 3) reflect on the impact the PD had on their teaching practice. Twenty-one secondary science teachers completed the Innovations in Science Instruction through Modeling (ISIM) program from 2007 through 2009. Commonalities in the written reflections and interview responses led to a set of generalizable findings related to the impacts and outcomes of the PD.

    To conduct a pilot study to test the feasibility and acceptability of using children's books to understand caregiver perceptions of parenting practices around common behavior challenges. A prospective 1-month pilot study was conducted in 3 community-based pediatric clinics serving lower income families living in central Indianapolis. One hundred caregivers of 4- to 7-year-old children presenting for a well-child visit chose 1 of 3 available children's books that dealt with a behavioral concern the caregiver reported having with the child. The book was read aloud to the child in the caregiver's presence by a trained research assistant and given to the families to take home. Outcomes measured were caregiver intent to change their interaction with their child after the book reading, as well as caregiver reports of changes in caregiver-child interactions at 1 month. Reading the book took an average of 3 minutes. Most (71%) caregivers reported intent to change after the book reading; two-thirds (47/71) were able to identify a specific technique or example illustrated in the story. One month later, all caregivers remembered receiving the book, and 91% reported reading the book to their child and/or sharing it with someone else. Three-fourths of caregivers (60/80) reported a change in caregiver-child interactions. The distribution of children's books with positive parenting content is a feasible and promising tool, and further study is warranted to see whether these books can serve as an effective brief intervention in pediatric primary care practice.

    The objective of this study is to identify points of agreement and disagreements among general practitioners (GPs) in Denmark concerning how the existential dimension is understood, and when and how it is integrated in the GP-patient encounter. A qualitative methodology with semi-structured focus group interviews was employed. General practice setting in Denmark. Thirty-one GPs from two Danish regions between 38 and 68 years of age participated in seven focus group interviews. Although understood to involve broad life conditions such as present and future being and identity, connectedness to a society and to other people, the existential dimension was primarily reported integrated in connection with life-threatening diseases and death. Furthermore, integration of the existential dimension was characterized as unsystematic and intuitive. Communication about religious or spiritual questions was mostly avoided by GPs due to shyness and perceived lack of expertise. GPs also reported infrequent referrals of patients to chaplains. GPs integrate issues related to the existential dimension in implicit and non-standardized ways and are hindered by cultural barriers. As a way to enhance a practice culture in which GPs pay more explicit attention to the patients' multidimensional concerns, opportunities for professional development could be offered (courses or seminars) that focus on mutual sharing of existential reflections, ideas and communication competencies. Key points Although integration of the existential dimension is recommended for patient care in general practice, little is known about GPs' understanding and integration of this dimension in the GP-patient encounter. The existential dimension is understood to involve broad and universal life conditions having no explicit reference to spiritual or religious aspects. The integration of the existential dimension is delimited to patient cases where life-threatening diseases, life crises and unexplainable patient

    Little is known about laypeople's practical understanding of a healthy diet, although this is important to successfully promote healthy eating. The present study is the first to experimentally examine how consumers define healthy and balanced food choices for an entire day compared with normal choices and compared with dietary guidelines. We used an extensive fake food buffet (FFB) with 179 foods commonly consumed in the Swiss diet. The FFB is a validated method to investigate food choice behaviour in a well-controlled laboratory setting. People from the general population in Switzerland (n 187; 51·9 % females), aged between 18 and 65 years, were randomly assigned to one of two conditions. In the control group, the participants were instructed to serve themselves foods they would eat on a normal day, whereas in the 'healthy' group they were instructed to choose foods representing a healthy diet. Participants chose significantly more healthy foods, with 4·5 g more dietary fibre, 2 % more protein and 2 % less SFA in the 'healthy' group compared with the control group. However, in both experimental conditions, participants served themselves foods containing twice as much sugar and salt than recommended by dietary guidelines. The results suggest that laypeople lack knowledge about the recommended portion sizes and the amounts of critical nutrients in processed food, which has important implications for communicating dietary guidelines. Furthermore, the energy of the food served was substantially correlated with the energy needs of the participants, demonstrating the potential of the fake food buffet method.

    Different investigations have been developed to address the uncertainty and quality evaluations leading to improve landslide hazard and risk assessment. With no doubt, and by using a wide range of scientific and technical approaches, they have contributed to a major extent to the understanding of the dynamics of landslide processes at different scales. Nonetheless, in a similar fashion than other hazards, it has been rather difficult to assess in a precise manner the multi-dimensions of their associated vulnerability and what is more, to effectively link risk assessments with disaster risk management. Owing to the double-character of landslide events, as natural and socio-natural hazards, mass movements turn out to be very complex processes, as their occurrence is also enhanced by population growth, socio-economic inequality, urbanization processes, land-degradation, unsustainable practices and mounting hazard exposure. Disaster Risk Management rope in the actions to attain Disaster Risk Reduction. The latter aims at decreasing existing hazard, vulnerability, and exposure, in addition to strengthening resilience, and very importantly, avoiding the construction of future disaster risk (UNISDR, 2015a). More specifically, and along the same line of ideas, the new-fangled Sendai Framework for Disaster Risk Reduction (SFDRR) 2015-2030 (UNISDR, 2015b) points towards reducing disaster risk and losses by engaging in a series of actions at local, national and global levels. Among them and of utterly significance are those initiatives related to the need of moving from risk assessment into disaster risk management. Consequently, and beyond championing scientific and technical capacity to strengthen landslide knowledge to assess vulnerability, hazard exposure and disaster risks, the challenge remains in the realm of promoting and improving permanent communication, dialogue and partnership among the science and technology communities, policymakers and other stakeholders

    Scalone, Giovanna

    using appraisal analysis to show how students talking about their images of science yield different ways of knowing and dispositions in science. Thirdly, by tracing the inclination and obligation of doing science, I illustrate how subjectivity versus materiality/objectivity in science impact how students perceive science. Fourth, student images of science, ways of identifying with science and having agency in science are analyzed using a thematic analysis to identify patterns and emerging themes. Next, I assess students' developing understanding of scientific inquiry using HLM to determine whether the Agency units versus the Inquiry units predicted students' learning outcomes based on the inquiry assessment. Finally, I discuss the implications of these analyses. This study accounts for how youth develop practice-linked identities in science entails the fleeting identity performances and language choices made for and by youth in the science classroom. Central to this notion of identity is agency where positionality as well as material and symbolic, interactional and situational resources constrain or enable identity development. In a learning context, these choices and values inherent in language use are relational to learner agency outside of language, but ensouled in performative curating where solidarity, intention, creativity, emotion, accountability, anticipation, cognition, and rewards enable the capacity to transform the self, others, and communities. This dissertation demonstrates how design features embedded in curriculum related to personal relevance and the societal context for science affords teachers to engage youth in agentic science learning in the classroom in ways that become more meaningful and supportive of science identification than traditional inquiry approaches to teaching science.

  19. Graphical methods and Cold War scientific practice: the Stommel Diagram's intriguing journey from the physical to the biological environmental sciences.

    2010-01-01

    In the last quarter of the twentieth century, an innovative three-dimensional graphical technique was introduced into biological oceanography and ecology, where it spread rapidly. Used to improve scientists' understanding of the importance of scale within oceanic ecosystems, this influential diagram addressed biological scales from phytoplankton to fish, physical scales from diurnal tides to ocean currents, and temporal scales from hours to ice ages. Yet the Stommel Diagram (named for physical oceanographer Henry Stommel, who created it in 1963) had not been devised to aid ecological investigations. Rather, Stommel intended it to help plan large-scale research programs in physical oceanography, particularly as Cold War research funding enabled a dramatic expansion of physical oceanography in the 1960s. Marine ecologists utilized the Stommel Diagram to enhance research on biological production in ocean environments, a key concern by the 1970s amid growing alarm about overfishing and ocean pollution. Before the end of the twentieth century, the diagram had become a significant tool within the discipline of ecology. Tracing the path that Stommel's graphical techniques traveled from the physical to the biological environmental sciences reveals a great deal about practices in these distinct research communities and their relative professional and institutional standings in the Cold War era. Crucial to appreciating the course of that path is an understanding of the divergent intellectual and social contexts of the physical versus the biological environmental sciences.

  20. Five male preservice elementary teachers: Their understandings, beliefs and practice regarding science teaching

    Hoover, Barbara Grambo

    Many factors influence teacher choices concerning the frequency, instructional methods, and content of science teaching. Although the role of gender in science learning has been studied extensively, the gender of elementary teachers as it intersects their teaching of science has not been investigated. In this ethnographic study, I focused on five male preservice elementary teachers as they experienced their student teaching internship, aiming to understand their underlying beliefs about science and science teaching and how those beliefs influenced their practice. In an attempt to illuminate the complex interplay of personality, experience, interests, and gender in the professional lives of these men, this study emphasized the importance of context in the formation and expression of their science beliefs and pedagogy. For this reason, I collected data from a number of sources. From September, 2001 to May, 2002, I observed my participants in their science methods courses and on multiple occasions as they taught science in elementary classrooms in a suburban school district. I reviewed journal entries required for the science methods class and examined documents such as handouts, readings and teacher guides from their elementary teaching experience. I conducted semi-structured and informal interviews. I analyzed data from these sources using grounded theory methodology. Although these five men had many similarities, they differed in their love of science, their exposure to science, their avocational interests, and their views of science pedagogy. This study, however, revealed a unifying theme: each participant had his own set of personal and academic resources that he carried into the classroom and used to construct a distinctive science learning environment. Some of these resources intersect with gender. For example, several men had science-related avocational interests. There was a common emphasis on creating a relaxed, enjoyable, hands-on teaching environment as

    Forestry Best Management Practices (BMPs) are critical in ensuring sustainable forest management in the United States because of their effectiveness in protecting water quality, reducing soil erosion, maintaining riparian habitat, and sustaining site productivity. The success of forestry BMPs depends heavily on coordination among primary stakeholder groups. It is important to understand perceptions of such groups for a successful forest policy formulation. We used the SWOT-AHP (Strengths, Weaknesses, Opportunities, and Threats analysis with the Analytical Hierarchy Process) framework to assess perceptions of three stakeholder groups (loggers, landowners, agency foresters) about forestry BMPs in Georgia, the largest roundwood producing state in the United States. The agency and logger stakeholder groups gave the highest priority to improved reputation under the strength category, whereas the landowner stakeholder group perceived sustainable forestry as the highest priority under the same category. Lack of landowner education was the highest priority under the weakness category for landowner and agency stakeholder groups, whereas the logger stakeholder group selected lack of trained personnel as the highest priority under the same category. Agency and landowner stakeholder groups gave the highest priority to training and education while loggers indicated maintenance of forest-based environmental benefits as their highest priority under the opportunity category. Finally, landowners and agency stakeholder groups perceived more regulations and restrictions as most significant in the threat category whereas the logger stakeholder group was most concerned about the insufficient accounting of cost sharing under the same category. Overall, selected stakeholder groups recognize the importance of forestry BMPs and had positive perceptions about them. A collaborative approach based on continuous feedback can streamline expectations of stakeholder groups about forestry BMPs in

  2. Promoting Science Learning and Scientific Identification through Contemporary Scientific Investigations

    Science.gov (United States)

    Van Horne, Katie

    This dissertation investigates the implementation issues and the educational opportunities associated with "taking the practice turn" in science education. This pedagogical shift focuses instructional experiences on engaging students in the epistemic practices of science both to learn the core ideas of the disciplines, as well as to gain an understanding of and personal connection to the scientific enterprise. In Chapter 2, I examine the teacher-researcher co-design collaboration that supported the classroom implementation of a year-long, project-based biology curriculum that was under development. This study explores the dilemmas that arose when teachers implemented a new intervention and how the dilemmas arose and were managed throughout the collaboration of researchers and teachers and between the teachers. In the design-based research of Chapter 3, I demonstrate how students' engagement in epistemic practices in contemporary science investigations supported their conceptual development about genetics. The analysis shows how this involved a complex interaction between the scientific, school and community practices in students' lives and how through varied participation in the practices students come to write about and recognize how contemporary investigations can give them leverage for science-based action outside of the school setting. Finally, Chapter 4 explores the characteristics of learning environments for supporting the development of scientific practice-linked identities. Specific features of the learning environment---access to the intellectual work of the domain, authentic roles and accountability, space to make meaningful contributions in relation to personal interests, and practice-linked identity resources that arose from interactions in the learning setting---supported learners in stabilizing practice-linked science identities through their engagement in contemporary scientific practices. This set of studies shows that providing students with the

  13. Scientific Research: Commodities or Commons?

    Science.gov (United States)

    Vermeir, Koen

    2013-10-01

    Truth is for sale today, some critics claim. The increased commodification of science corrupts it, scientific fraud is rampant and the age-old trust in science is shattered. This cynical view, although gaining in prominence, does not explain very well the surprising motivation and integrity that is still central to the scientific life. Although scientific knowledge becomes more and more treated as a commodity or as a product that is for sale, a central part of academic scientific practice is still organized according to different principles. In this paper, I critically analyze alternative models for understanding the organization of knowledge, such as the idea of the scientific commons and the gift economy of science. After weighing the diverse positive and negative aspects of free market economies of science and gift economies of science, a commons structured as a gift economy seems best suited to preserve and take advantage of the specific character of scientific knowledge. Furthermore, commons and gift economies promote the rich social texture that is important for supporting central norms of science. Some of these basic norms might break down if the gift character of science is lost. To conclude, I consider the possibility and desirability of hybrid economies of academic science, which combine aspects of gift economies and free market economies. The aim of this paper is to gain a better understanding of these deeper structural challenges faced by science policy. Such theoretical reflections should eventually assist us in formulating new policy guidelines.

    2012-11-01

      To investigate the process of patient satisfaction with nurse-led chronic disease management in Australian general practice.   Nurses working in the primary care context of general practice, referred to as practice nurses, are expanding their role in chronic disease management; this is relatively new to Australia. Therefore, determining patient satisfaction with this trend is pragmatically and ethically important. However, the concept of patient satisfaction is not well understood particularly in relation to care provided by practice nurses.   A grounded theory study underpinned by a relativist ontological position and a relativist epistemology.   Grounded theory was used to develop a theory from data collected through in-depth interviews with 38 participants between November 2007-April 2009. Participants were drawn from a larger project that trialled a practice nurse-led, collaborative model of chronic disease management in three Australian general practices. Theoretical sampling, data collection, and analysis were conducted concurrently consistent with grounded theory methods.   Patients undergo a cyclical process of Navigating Care involving three stages, Determining Care Needs, Forming Relationship, and Having Confidence. The latter two processes are inter-related and a feedback loop from them informs subsequent cycles of Determining Care Needs. If any of these steps fails to develop adequately, patients are likely to opt out of nurse-led care.   Navigating Care explains how and why time, communication, continuity, and trust in general practitioners and nurses are important to patient satisfaction. It can be used in identifying suitable patients for practice nurse-led care and to inform the practice and organization of practice nurse-led care to enhance patient satisfaction. © 2012 Blackwell Publishing Ltd.

    Steltzer, H.; House, B.

    2017-12-01

    In August 2015, 3 million gallons of acidic mine water flooded into a mountain stream, then flowed into the Animas River and the San Juan River. Downstream communities in Colorado, New Mexico and Utah watched in shock as the rivers on which they depend turned an unworldly orange color. As a result, water color currently drives public concern about river health. Data collected by the US Environmental Protection Agency and local and state public health indicate that water color does not correspond with health risk. Health risk is driven by river chemistry that cannot be seen, and river chemistry and quantity vary seasonally and due to precipitation events. Rivers have a pulse, one that is both regular and irregular, some aspects of which can be seen and others that cannot be seen. As a science communicator, I wanted to know if art could communicate the `pulse of the river', helping people to understand the dynamic quality of mountain rivers, and why scientific data is needed to determine health risk. Brian's vision was to do this through sound with real-time data on river water chemistry generating tones so that we can hear what we can't see. Through art, complex data on our world and how it is changing can be shared, reach more people, and lead to new dialogue. These conversations are much needed as we work to manage for global environmental issues.

    Full Text Available This article reflects the main theoretical proposals about the relations between theory and practice that are have been formulated in the field of teacher training. The problem that is at the bottom of the theory-practice relationship: professional alienation of teachers in education. To overcome this mostly two responses have been: focus on the theory: convert to the teacher in an intellectual, and the proposal focus on the practice: assess the importance of the personal practical knowledge of teachers. Halfway between both perspectives it is possible to raise three current and relevant lines of research for studies to illuminate the relations between theory-practice in teacher training: (1 teacher’s thought and implicit theories, (2 the reflective teacher and (3 the formulation of principles of procedure and action research and theories experienced. This review haves the objective of reveal the complexity of linked thought, research and teaching action; but it also allows us move forward in building a comprehensive framework covering various forms of approach to a subject which lies at the base of any discussion on the teaching profession and advance in the challenge of achieving a practical domain and a critical awareness in the teaching.

    Full Text Available This position paper focuses on Nynorsk in the digital era and the need for research-based knowledge about it in school settings in Norway. The Norwegian language situation is exceptional because Norway has two written standards, Bokmål (majority variety and Nynorsk (minority variety, and both the Education Act and the Norwegian Directorate of Education require that publishers provide parallel editions of all paper-based and digital learning aids for pupils. However, a national report by Skjær,Eiksund, Fretland, Holen & Netteland(2008 revealed that few publishers have developed and offered digital learning aids in Nynorsk. In 2015 the situation appears to be largely unchanged, even though the authorities, language organisations and “leadings lights” have taken several initiatives to encourage compliance with the Education Act; however, what is needed is further research into the situation of parallel editions of digital learning aids. This is of particular interest today since the pupils in the county with the highest rate (97% of Nynorsk-pupils has consistently been at the top of the list as one of the best performing counties in Norway in national tests since 2006 (Directorate of Education 2015. In addition, Vangsnes, Söderlund & Blekesaune (2015 find that municipalities in Norway with more than 50% Nynorsk-pupils achieve better in National tests when compared to Bokmål municipalities. The main message in our position paper is that the digital revolution might have changed some underlying premises for how we understand and use language and dialects, and the need for parallel editions of digital learning aids in Bokmål and Nynorsk is no longer a question of economics or of political statements for or against Nynorsk, etc., but is instead a question of a more nuanced scientific understanding of learning and achievement in today’s digitized school. The achievements of Nynorsk pupils in national tests is one indicator of school

  1. Representational Classroom Practices that Contribute to Students' Conceptual and Representational Understanding of Chemical Bonding

    2011-11-01

    Understanding bonding is fundamental to success in chemistry. A number of alternative conceptions related to chemical bonding have been reported in the literature. Research suggests that many alternative conceptions held by chemistry students result from previous teaching; if teachers are explicit in the use of representations and explain their content-specific forms and functions, this might be avoided. The development of an understanding of and ability to use multiple representations is crucial to students' understanding of chemical bonding. This paper draws on data from a larger study involving two Year 11 chemistry classes (n = 27, n = 22). It explores the contribution of explicit instruction about multiple representations to students' understanding and representation of chemical bonding. The instructional strategies were documented using audio-recordings and the teacher-researcher's reflection journal. Pre-test-post-test comparisons showed an improvement in conceptual understanding and representational competence. Analysis of the students' texts provided further evidence of the students' ability to use multiple representations to explain macroscopic phenomena on the molecular level. The findings suggest that explicit instruction about representational form and function contributes to the enhancement of representational competence and conceptual understanding of bonding in chemistry. However, the scaffolding strategies employed by the teacher play an important role in the learning process. This research has implications for professional development enhancing teachers' approaches to these aspects of instruction around chemical bonding.

  2. Understanding partnership practice in primary health as pedagogic work: what can Vygotsky's theory of learning offer?

    Science.gov (United States)

    Hopwood, Nick

    2015-01-01

    Primary health policy in Australia has followed international trends in promoting models of care based on partnership between professionals and health service users. This reform agenda has significant practice implications, and has been widely adopted in areas of primary health that involve supporting families with children. Existing research shows that achieving partnership in practice is associated with three specific challenges: uncertainty regarding the role of professional expertise, tension between immediate needs and longer-term capacity development in families, and the need for challenge while maintaining relationships based on trust. Recently, pedagogic or learning-focussed elements of partnership practice have been identified, but there have been no systematic attempts to link theories of learning with the practices and challenges of primary health-care professionals working with families in a pedagogic role. This paper explores key concepts of Vygotsky's theory of learning (including mediation, the zone of proximal development, internalisation, and double stimulation), showing how pedagogic concepts can provide a bridge between the policy rhetoric of partnership and primary health practice. The use of this theory to address the three key challenges is explicitly discussed.

    In this study, we establish a set of 19 influential factors on the implementation of Green Supply Chain Management (GSCM) practices and analyse the interaction between these factors and their effect on the implementation of GSCM practices using the Interpretive Structural Modelling (ISM) method and the "Matrice d'Impacts Croisés Multiplication Appliquée à un Classement" (MICMAC) analysis on data compiled from interviews with supply chain (SC) executives based in the Gulf countries (Middle East region). The study reveals a strong influence and driving power of the nature of the relationships between SC partners on the implementation of GSCM practices. We especially found that dependence, trust, and durability of the relationship with SC partners have a very high influence. In addition, the size of the company, the top management commitment, the implementation of quality management and the employees training and education exert a critical influence on the implementation of GSCM practices. Contextual elements such as the industry sector and region and their effect on the prominence of specific factors are also highlighted through our study. Finally, implications for research and practice are discussed. Copyright © 2016 Elsevier Ltd. All rights reserved.

  7. [Tone psychology and music research as catalysts of experimental-scientific practice and methodology in the circle of Carl Stumpf].

    Klotz, Sebastian

    2008-09-01

    The study of acoustics, harmonics and of music has been providing scientific models since Greek Antiquity. Since the early modern ages, two separate cultures began to emerge out of the study of music: a technical acoustics and an aesthetically and philosophically inspired musical criticism. In the writings of Johann Friedrich Herbart (1811) a scientific approach to musical aesthetics and to music perception is taking shape that reinstalls the listening process as a highly complex and logical phenomenon. By opening music for a scientific psychological investigation, Herbart pioneered the physiologically and acoustically grounded seminal work by Hermann von Helmholtz On the sensations of tone (1863) which the author considered a prerequisite for musical aesthetics and music theory. Helmholtz in turn inspired the philosopher and psychologist Carl Stumpf to further investigate musical perception (beginning in 1883). To Stumpf, it provided a paradigm for experimental psychology as mental functions and phenomena could be studied in detail. These functions and phenomena are the actual objects of scientific study in Stumpf's inductive and descriptive psychology. Combining insights from statistics, ethnology, anthropology, psychoacoustics and the cultural history of mankind, Stumpf and his team developed a new blend of science which absorbs styles of reasoning, analytical procedures and academic convictions from natural history, the natural sciences and the humanities but at the same time identifies shortcomings of these approaches that fail to grasp the complexities of psychic functions. Despite their reliance on the quasi-objective phonograph and despite their commitment to objectivity, precision and measurement, mental phenomena relating to tonal perception and to music provided too complex a challenge to be easily articulated and shared by the scientific community after 1900. The essay illustrates these tensions against the background of a history of objectivity.

    Conventional instruction in science often proceeds from the general to the specific and from text to action. Fundamental terminologies, concepts, and ideas that are often abstract are taught first and only after such introductory processes can a student engage in research. Many students struggle to find relevance when presented information without context specific to their own experiences. This challenge is exacerbated for students whose social circles do not include adults who can validate scientific learning from their own experiences. Lamont-Doherty's Secondary School Field Research Program inverts the standard paradigm and places small groups of students in research projects where they begin by performing manageable tasks on complex applied research projects. These tasks are supplemented with informal mentoring and relevant articles (~1 per week). Quantitative metrics suggest the approach is highly successful—most participants report a dramatic increase in their enthusiasm for science, 100% attend college, and approximately 50% declare majors in science or technology. We use one project, the construction of a microbial battery, to illustrate this novel model of science learning and argue that it should be considered a best practice for project-based science education. The goal of this project was to build a rechargeable battery for a mobile phone based on a geochemical cycle, to generate and store electricity. The students, mostly from ethnic groups under-represented in the STEM fields, combined concepts and laboratory methods from biology, chemistry and physics to isolate photosynthetic bacteria from a natural salt marsh, and made an in situ device capable of powering a light bulb. The younger participants had been exposed to neither high school chemistry nor physics at the start of the project, yet they were able to use the project as a platform to deepen their science knowledge and their desire for increased participation in formal science education.

    Moore, Kelsey; Talwar, Victoria; Moxley-Haegert, Linda

    2015-03-01

    In pediatric settings, parents and children often seek spiritual and religious support from their healthcare provider, as they try to find meaning in their illness. Narrative practices, such as definitional ceremonies, can provide a unique framework for psychologists to explore children's spirituality and its role in the midst of illness. In addition, definitional ceremonies can be used as a means for psychologists to inform interdisciplinary teams' understanding of children's spirituality and its relevance in pediatric treatment settings. In this article, our objectives are to (a) provide a brief overview of the literature on children's spirituality, (b) review some of the literature on childhood cancer patients' spirituality, (c) highlight the importance of whole-person care for diverse pediatric patients, and (d) introduce definitional ceremonies as appropriate narrative practices that psychologists can use to both guide their therapy and inform interdisciplinary teams' understanding of children's spirituality. © The Author(s) 2015.

    2013-10-01

    Examining the meanings of the experiences of advanced practice nurses (APNs) who chose to work with older adults and why they continue to work with this population was the focus of this hermeneutic qualitative research study. Twelve geriatric APNs currently practicing in two South Central states were interviewed using an open-ended interview guide. Using Gadamerian hermeneutics, the researchers identified Gerontology Found Me as the significant expression that reflected the fundamental meaning of the experience as a whole. Four themes emerged that further described the meanings of the participants' personal, educational, and professional experiences: Becoming a Gerontology Nurse, Being a Gerontology Nurse, Belonging to Gerontology, and Bringing Others to Gerontology. This study concluded that APNs' personal and professional experiences were more influential than educational experiences to become geriatric nurses, and having these personal and professional experiences of being in relationship with older individuals further contributed to their choice of gerontology.

    Full Text Available Introduction: The expansion of the multi-professional team in Primary Health Care (APS input professional categories that have traditionally worked in the service of medium and high complexity. The lack of knowledge on the assignments of these new jobs can be an obstacle to effective interdisciplinary and sharing practices. Objective: The study aimed to analyze the professional healthcare team understanding on the Family and Support Center for Family Health (NASF and the practices of Occupational Therapy in APS, as a member of NASF team. Method: This study is characterized as exploratory and qualitative field, with data collected individually, through semi-structured interviews with professionals of a Family Health Team and a NASF team. We used content analysis for data processing. Results: We identified that the understanding of the teams on the role of the occupational therapist is partial, linking their practices basically with mental health and rehabilitation, confusing their duties with the other team members. Conclusion: It was difficult to differentiate occupational therapist own practices, even when the work is shared. This suggests the need to implement strategies, such as matrix-based strategies to overcome the gaps in knowledge between the team and the specifics of each profession engaged in APS.

  17. Using Social Marketing Principles to Understand an Extension Audience’s Landscape Water Conservation Practices

    2015-02-01

    Full Text Available A substantial amount of water is applied to Florida landscapes, and encouraging water conservation through irrigation practices has been identified as a priority programming area where there is great opportunity to positively affect the state’s water resources. Florida Extension addresses this priority area through educational programming. Social marketing has been identified as a promising approach to changing behaviors that influence environmental issues, such as water-saving irrigation technologies and practices. This approach recognizes that there are barriers that prevent individuals from engaging in positive behavior changes. This study evaluated an irrigation seminar using a retrospective pretest-posttest design that incorporated elements of a social marketing intercept survey. Thirty-four attendees participated and primarily represented green industry professional and government sectors. Study objectives were to evaluate the workshop and describe the audience using social marketing principles for future program planning based on audience research. The audience rated their descriptive norms, a strong predictor of behavioral change, lower than their injunctive norms, a less robust predictor. The majority planned to adopt at least one water-conservation best management practice as a result of the workshop. We make recommendations for applying social marketing principles to Extension programming.

The understanding of the precise hierarchical relations between them, that reflect the phylo- and ontogenetic evolutionary pathway for adaptation to the complex interpersonal and socio-cultural environment, has an essential application in psychopathology and psychotherapy, in particular for those clinical conditions where the normal integration of high order mental functions is hampered by developmental relational trauma.

    Full Text Available This article discusses the relationship between the private international oil company (IOC Royal Dutch Shell and Russia as an oil producing and oil exporting state during a period when oil prices were moving towards unforeseen heights (2005-2007. By examining this dynamic relationship, this study aims to contribute to an understanding of Russia’s discursive and culturally produced history. The history of a state-oil company interaction has shown that the use of legal instruments is a good indicator to determine the nature of the relationship between oil-producing states and IOCs – a relationship that often has been characterized by periods of cooperation or conflict.At the centre of inquiry is how the oil major understands the law in Russia, and in particular the enforcement of the country’s formal written rules during legal conflicts over the development of the Sakhalin-II oil and gas fields (in which Shell until December 2006 controlled a majority stake. After identifying the violations of formal laws, I conclude that Shell understands that the formal rules of the game are subordinate to the unwritten laws of energy politics and in particular the informal demands of contemporary Russian society. The article also illustrates that oil-producing states have the upper hand in conflicts over the development of oil and gas resources.

  2. Understanding empathy: why phenomenology and hermeneutics can help medical education and practice.

    2015-11-01

    This article offers a critique and reformulation of the concept of empathy as it is currently used in the context of medicine and medical care. My argument is three pronged. First, that the instrumentalised notion of empathy that has been common within medicine erases the term's rich epistemological history as a special form of understanding, even a vehicle of social inquiry, and has instead substituted an account unsustainably structured according to the polarisations of modernity (subject/object, active/passive, knower/known, mind/body, doctor/patient). I suggest that understanding empathy by examining its origins within the phenomenological tradition, as a mode of intersubjective understanding, offers a different and profitable approach. Secondly, I argue that the appropriation of empathy in medicine means that, ironically, empathy can function as a technique of pastoral power, in which virtue, knowledge and authority remain with the doctor (Mayes in Bioeth Inq 6:483-493, doi: 10.1007/s11673-009-9195-9 , 2009). And thirdly, empathy is in danger of being resourced as a substitute for equity and funding within health systems. I conclude however with hope for the productive possibilities for empathy.

  4. Living with Invasive Plants in the Anthropocene: The Importance of Understanding Practice and Experience

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available The role of humans in facilitating the rapid spread of plants at a scale that is considered invasive is one manifestation of the Anthropocene, now framed as a geological period in which humans are the dominant force in landscape transformation. Invasive plant management faces intensified challenges, and can no longer be viewed in terms of ′eradication′ or ′restoration of original landscapes′. In this perspectives piece, we focus on the practice and experience of people engaged in invasive plant management, using examples from Australia and Canada. We show how managers 1 face several pragmatic trade-offs; 2 must reconcile diverse views, even within stakeholder groups; 3 must balance competing temporal scales; 4 encounter tensions with policy; and 5 face critical and under-acknowledged labour challenges. These themes show the variety of considerations based on which invasive plant managers make complex decisions about when, where, and how to intervene. Their widespread pragmatic acceptance of small, situated gains (as well as losses combines with impressive long-term commitments to the task of invasives management. We suggest that the actual practice of weed management challenges those academic perspectives that still aspire to attain pristine nature.

    This qualitative case study looks closely at an elementary teacher who participated in professional development experiences that helped her develop a hybrid practice of using inquiry-based science to teach both science content and English language development (ELD) to her students, many of whom are English language learners (ELLs). This case study examines the teacher's reflections on her teaching and her students' learning as she engaged her students in science learning and supported their developing language skills. It explicates the professional learning experiences that supported the development of this hybrid practice. Closely examining the pedagogical practice and reflections of a teacher who is developing an inquiry-based approach to both science learning and language development can provide insights into how teachers come to integrate their professional development experiences with their classroom expertise in order to create a hybrid inquiry-based science ELD practice. This qualitative case study contributes to the emerging scholarship on the development of teacher practice of inquiry-based science instruction as a vehicle for both science instruction and ELD for ELLs. This study demonstrates how an effective teaching practice that supports both the science and language learning of students can develop from ongoing professional learning experiences that are grounded in current perspectives about language development and that immerse teachers in an inquiry-based approach to learning and instruction. Additionally, this case study also underscores the important role that professional learning opportunities can play in supporting teachers in developing a deeper understanding of the affordances that inquiry-based science can provide for language development.

    2015-01-01

    Abstract Scientific inquiry represents a multifaceted approach to explore and understand the natural world. Training students in the principles of scientific inquiry can help promote the scientific learning process as well as help students enhance their understanding of scientific research. Here, we report on the development and implementation of a learning module that introduces astrobiology students to the concepts of creative and scientific inquiry, as well as provide practical exercises to build critical thinking skills. The module contained three distinct components: (1) a creative inquiry activity designed to introduce concepts regarding the role of creativity in scientific inquiry; (2) guidelines to help astrobiology students formulate and self-assess questions regarding various scientific content and imagery; and (3) a practical exercise where students were allowed to watch a scientific presentation and practice their analytical skills. Pre- and post-course surveys were used to assess the students' perceptions regarding creative and scientific inquiry and whether this activity impacted their understanding of the scientific process. Survey results indicate that the exercise helped improve students' science skills by promoting awareness regarding the role of creativity in scientific inquiry and building their confidence in formulating and assessing scientific questions. Together, the module and survey results confirm the need to include such inquiry-based activities into the higher education classroom, thereby helping students hone their critical thinking and question asking skill set and facilitating their professional development in astrobiology.

    The Colonia Glacier, a low elevation mid-latitude glacier, drains the lee side of the central division of the Northern Patagonian Ice Field (NPI). As such, it serves as a microcosm of conditions on the NPI as a whole. Glaciers of this type have experienced extreme variability in Holocene thickness and extent, making them excellent indicators of local and regional climate conditions. Glacial lake outburst floods (GLOFs) originating in the remote Cachet Basin, dammed by the Colonia Glacier, have increased in frequency from once every 10 years to 3 times annually since 2008. These flood events are important in that they 1.) directly impact the livelihoods of downstream residents, 2.) may be linked to the overall health of the Colonia Glacier and, to a larger extent, the NPI, 3.) provide a natural laboratory for studying the dynamics of large flood events, and 4.) have downcut the sediments sequestered in the upper basin, revealing a rich Holocene sedimentologic and climate record. With improved access to this remote region through local partners in recent years, outstanding opportunities for scientific discovery, education, and outreach exist in one of the most beautiful and least-studied glacial regions on Earth. We propose establishing an NSF REU site here to further develop the abundant educational and research opportunities in this spectacular locale. We envision students participating under the REU will receive a broad-based background in glaciology and sedimentology prior to the field experience, and then participate in basic field research led by the PIs into understanding recent and Holocene linkages between climate change and the glacio-fluvio geomorphology of the NPI. A pilot program of 13 U.S. and Chilean students with wide-ranging backgrounds and degree levels was conducted in the winter of 2015-16. A two week backcountry trek across rocky terrain, mountain streams, active glaciers, and proglacial lakes in this seldom-visited region immersed the students

    The infant mental health field can amplify its effects when it extends its purview beyond the dyad to the larger contexts in which infants and adult caregivers interact and develop over time. Within health, mental health, education, and other human service organizations, the quality of relationships is a critical variable in the individual-level outcomes that such organizations seek. The goals of this work and the means for accomplishing them are highly dependent on human qualities and interactions that are shaped by organizational processes. In communities, too, processes that shape relationships also strongly influence child-, family-, and community-level outcomes. The Touchpoints approach to reflective practice can guide relational processes among professionals, parents, and infants in organizations and communities that influence these outcomes. © 2016 Michigan Association for Infant Mental Health.

    2017-06-01

    Small and medium enterprises (SMEs) are a major source of dynamism, innovation and flexibility for emerging and developing countries, as well as for the economies of the most industrialised nations. However, the survival and growth of SMEs can be difficult in the current competitive business environment and global marketplace. It can be a real challenge to deliver the right product and service at the most opportune time and at the lowest possible cost to the right customer. The challenge stresses the importance of managing cross-boundary relationships between business partners. For gaining a competitive advantage, supply chain management (SCM) is an effective tool to SMEs. Therefore, this paper aims to review the tenet of SCM, its benefits and practices to SMEs.

    2015-01-01

    Nurses represent the largest professional group working with stroke-survivors, but there is limited evidence regarding nurses' involvement in post-stroke rehabilitation. The purpose of this study was to identify and explore the perspectives of nurses and other multidisciplinary stroke team members on nurses' practice in stroke rehabilitation. Q-methodological study with 63 multidisciplinary stroke unit team members and semi-structured interviews with 27 stroke unit team members. Irrespective of their professional backgrounds, participants shared the view that nurses can make an active contribution to stroke rehabilitation and integrate rehabilitation principles in routine practice. Training in stroke rehabilitation skills was viewed as fundamental to effective stroke care, but nurses do not routinely receive such training. The view that integrating rehabilitation techniques can only occur when nursing staffing levels were high was rejected. There was also little support for the view that nurses are uniquely placed to co-ordinate care, or that nurses have an independent rehabilitation role. The contribution that nurses with stroke rehabilitation skills can make to effective stroke care was understood. However, realising the potential of nurses as full partners in stroke rehabilitation is unlikely to occur without introduction of structured competency-based multidisciplinary training in rehabilitation skills. Implications for Rehabilitation Multidisciplinary rehabilitation in stroke units is a cornerstone of effective stroke care. Views of stroke unit team members on nurses' involvement in rehabilitation have not been reported previously. Nurses can routinely incorporate rehabilitation principles in their care. Specialist competency-based stroke rehabilitation training needs to be provided for nurses as well as for allied health professionals.

    Companies worldwide are turning to organizational communities of practice (OCoPs) as vehicles to generate learning and enhance organizational performance. OCoPs are defined as groups of employees who share a concern, a set of problems, or a passion about a topic and who strengthen their knowledge and expertise by interacting on a consistent basis. To date, OCoP research has drawn almost exclusively from the community of practice (CoP) literature, even though the organizational form of CoPs shares attributes of traditional CoPs and of organizational teams. Drawing on Lave and Wenger's (1991) original theory of legitimate peripheral participation, we integrate theory and research from CoPs and organizational teams to develop and empirically examine a model of OCoP effectiveness that includes constructs such as leadership, empowerment, the structure of tasks, and OCoP relevance to organizational effectiveness. Using data from 32 OCoPs in a U.S.-based multinational mining and minerals processing firm, we found that external community leaders play an important role in enhancing OCoP empowerment, particularly to the extent that task interdependence is high. Empowerment, in turn, was positively related to OCoP effectiveness. We also found that OCoPs designated as "core" by the organization (e.g., working on critical issues) were more effective than those that were noncore. Task interdependence also was positively related to OCoP effectiveness. We provide scholars and practitioners with insights on how to effectively manage OCoPs in today's organizations.

    Review the current status of liver transplantation for patients with alcohol use disorder (AUD). Alcohol-related liver disease (ALD) will increase as a source of patients requiring liver transplantation. Attitudes to use of liver transplantation as rescue therapy for patients with severe alcohol-related hepatitis are changing. The long-term health of ALD liver transplantation recipients requires continued assistance to patients with AUD. Liver transplantation of patients with ALD increased during the last decade and we predict that this trend will continue because of the decline in the number of hepatitis C virus-infected candidates. Concomitantly, a shift in the selection for liver transplantation has occurred of patients with severe alcohol-related hepatitis not responding to medical therapy. Although rescue liver transplantation is a valuable option for patients with severe alcohol-related hepatitis, worldwide practice regarding rescue liver transplantation remains very heterogeneous. There is increasing recognition that excessive consumption of alcohol after liver transplantation is harmful to graft function and patient survival. Factors associated with relapse are younger age at liver transplantation and shorter duration of sobriety prior to liver transplantation. The long-term health of the ALD liver transplant recipient requires continued assistance regarding AUD, a lifelong disorder of craving, relapse, and remission. However, there have been very few studies evaluating best practices for long-term addiction care in transplant recipients. After liver transplantation, the prevalence of cardiovascular disease, infections, and cancer increases over time. Addiction to tobacco constitutes an important issue that must be considered as tobacco cessation may decrease the incidence of tobacco-related cardiovascular and lung disease and aerodigestive cancers.

    Nonadherence to antiepileptic drugs (AEDs) is a common cause of poor seizure control. This study examines whether reported adherence to AEDs is related to variables identified in the National Institute for Health and Clinical Excellence (NICE) Medicines Adherence Guidelines as being important to adherence: perceptual factors (AED necessity beliefs and concerns), practical factors (limitations in capability and resources), and perceptions of involvement in treatment decisions. This was a cross-sectional study of people with epilepsy receiving AEDs. Participants completed an online survey hosted by the Epilepsy Society (n = 1,010), or as an audit during inpatient admission (n = 118). Validated questionnaires, adapted for epilepsy, assessed reported adherence to AEDs (Medication Adherence Report Scale [MARS]), perceptions of AEDs (Beliefs about Medicines Questionnaire [BMQ]), and patient perceptions of involvement in treatment decisions (Treatment Empowerment Scale [TES]). Low adherence was related to AED beliefs (doubts about necessity: t(577) = 3.90, p < 0.001; and concerns: t(995) = 3.45, p = 0.001), reported limitations in capability and resources (t(589) = 7.78, p < 0.001), and to perceptions of a lack of involvement in treatment decisions (t(623) = 4.48, p < 0.001). In multiple logistic regression analyses, these factors significantly (p < 0.001) increased variance in reported adherence, above that which could be explained by age and clinical variables (seizure frequency, type, epilepsy duration, number of AEDs prescribed). Variables identified in the NICE Medicines Adherence Guidelines as potentially important factors for adherence were found to be related to adherence to AEDs. These factors are potentially modifiable. Interventions to support optimal adherence to AEDs should be tailored to address doubts about AED necessity and concerns about harm, and to overcome practical difficulties, while engaging patients in treatment decisions.

    2017-12-01

    Full Text Available One of the challenges in analyzing youth who participated in the recent Arab uprisings relates to explaining and understanding their revolutionary practices. Adopting a leaderless and cross-ideological form of mobilization, youth during the eighteen days of the Egyptian uprising managed to practice inclusion by uniting a diverse group of Egyptians. After toppling Mubarak, the revolutionary youth, however, did not present themselves as aiming to seize power, a defining feature of revolutions at least until the 1970s. To understand the meaning of these new cross-ideological and leaderless forms of mobilization, I suggest understanding youth within their time and space. Drawing on Alain Badiou and his conception of the intervallic period and the rebirth of history through the Arab revolts, this article highlights important differences among this generation in their conception of doing politics. More specifically, this paper focuses on the changed meaning of the hero figure, highlighting the importance of inclusionary politics. It will suggest that since the 2011 revolutionary event, a shift away from traditional politics based on a leader and an ideology is being contested for a more inclusionary politics as desired by the younger generation in Egypt.

    Stenner, Rob; Mitchell, Theresa; Palmer, Shea

    2017-09-01

    This paper provides an overview of Philosophical Hermeneutics based on the work of German philosopher Hans Georg Gadamer. The concepts of the 'hermeneutic circle' as a vehicle for interpretation, management of the researcher's pre-understandings (prejudices), and the 'fusion of horizons' are introduced and illustrated by examples from the first author's research, before considering how rigour can be achieved in this type of research. The actual research study which aimed to explore how shared decision making and patient partnership are addressed by physiotherapists in the process of exercise prescription for patients with low back pain (LBP) is not the focus of this paper. However short descriptions of the study are used to explore issues surrounding a hermeneutic inquiry. For physiotherapists interested in research or considering undertaking an interpretive phenomenological inquiry, this theoretical discussion paper explores how Gadamer's philosophy offers a credible framework for undertaking such research.

    Private sector accredited drug dispensing outlets in Morogoro and pharmacies in Dar es Salaam, Tanzania. To assess 1) the level of knowledge about tuberculosis (TB) among dispensers in Tanzania's retail pharmaceutical sector; 2) practices related to identification of patients with suspected TB; 3) the availability of educational materials and training; and 4) the availability of first- and second-line anti-tuberculosis treatment in retail drug outlets. A cross-sectional descriptive study involving the administration of a structured questionnaire among drug dispensers in 122 pharmacies and 173 accredited drug dispensing outlets. Private retail drug outlets are convenient; most are open at least 12 h per day, 7 days/week. Although 95% of dispensers identified persistent cough as a symptom of TB, only 1% had received TB-related training in the previous 3 years; 8% of outlets stocked first-line anti-tuberculosis medicines, which are legally prohibited from being sold at retail outlets. The majority of respondents reported seeing clients with TB-like symptoms, and of these 95% reported frequently referring clients to nearby health facilities. Private retail pharmaceutical outlets can potentially contribute to TB case detection and treatment; however, a coordinated effort is needed to train dispensers and implement appropriate referral procedures.

    Peer review is an important element of scientific communication but deserves quantitative examination. We used data from the handling service manuscript Central for ten mid-tier ecology and evolution journals to test whether number of external reviews completed improved citation rates for all accepted manuscripts. Contrary to a previous study examining this issue using resubmission data as a proxy for reviews, we show that citation rates of manuscripts do not correlate with the number of individuals that provided reviews. Importantly, externally-reviewed papers do not outperform editor-only reviewed published papers in terms of visibility within a 5-year citation window. These findings suggest that in many instances editors can be all that is needed to review papers (or at least conduct the critical first review to assess general suitability) if the purpose of peer review is to primarily filter and that journals can consider reducing the number of referees associated with reviewing ecology and evolution papers.

    2012-01-01

    Purpose of Review Teen Dating Violence (TDV) is a serious and potentially lethal form of relationship violence in adolescence. TDV is highly correlated with several outcomes related to poor physical and mental health. Although incidence and prevalence data indicates high rates of exposure to TDV among adolescents throughout the United States, significant confusion remains in healthcare communities concerning the definition and implications of TDV. Additionally, healthcare providers are uncertain about effective screening and intervention methods. The article will review the definition and epidemiology of TDV and discuss possible screening and intervention strategies. Recent Findings TDV research is a relatively new addition to the field of relationship violence. Although some confusion remains, the definition and epidemiology of TDV is better understood which has greatly lead to effective ways in which to screen and intervene when such violence is detected. Universal screening with a focus on high risk subgroups combined with referrals to local and national support services are key steps in reducing both primary and secondary exposure. Summary TDV is a widespread public health crisis with serious short and long-term implications. It is necessary for pediatric and adolescent healthcare providers to be aware of TDV, its potential repercussions, as well as possible methods for screening and intervention. More research is needed to better understand TDV as well as to further define effective screening and intervention protocol for the clinical environment. PMID:21670679

    Curriculum ideals often get compromised as a curriculum moves through its various levels of representation. Across the different science reforms, this process of slippage is clearly present. Research shows that teacher subject matter knowledge, PCK, beliefs and context factors all influence implementation. Professional development arrangements focus on fixing deficiencies in teachers' knowledge, beliefs or work context. This approach has not solved the problem of slippage, as we still do not understand what mechanisms operate when teachers make decisions about change proposals. In this study, we unpacked the decision mechanisms of three highly qualified chemistry teachers who subsequently adapted an innovative context-based chemistry unit. In spite of a state of the art professional development arrangement and the teachers being highly qualified, slippage occurred. The teachers' goal systems were used to interpret their reasoning. A goal system is a context-dependent, within-person mental construct that consists of a hierarchy of a person's goals and means in pursuit of a task. We showed that all three teachers adopted or redesigned elements of the change proposals to meet their core goals, i.e., goals that had multiple connections with other goals. This indicated that the adaptations teachers made were perfectly reasonable ways to serve their professional goals. For change to happen, we contend that one should begin with ways to connect teachers' core goals with the lesson or unit goal demands of a proposed innovation. Change emerges from the adaptions teachers make in the service of their core goals.

  7. Understanding Positive Play: An Exploration of Playing Experiences and Responsible Gambling Practices.

    This study is one of the first to explore in detail the behaviors, attitudes and motivations of players that show no signs of at-risk or problem gambling behavior (so-called 'positive players'). Via an online survey, 1484 positive players were compared with 209 problem players identified using the Lie/Bet screen. The study identified two distinct groups of positive players defined according to their motivations to play and their engagement with responsible gambling (RG) practices. Those positive players that played most frequently employed the most personal RG strategies. Reasons that positive players gave for gambling were focused on leisure (e.g., playing for fun, being entertained, and/or winning a prize). By contrast, problem gamblers were much more focused upon modifying mood states (e.g., excitement, relaxation, depression and playing when bored or upset). The present study also suggests that online gambling is not, by default, inherently riskier than gambling in more traditional ways, as online gambling was the most popular media by which positive players gambled. Furthermore, most positive players reported that it was easier to stick to their limits when playing the National Lottery online compared to traditional retail purchasing of tickets. Problem players were significantly more likely than positive players to gamble with family and friends, suggesting that, contrary to a popular RG message, social play may not be inherently safer than gambling alone. It is proposed that players (generally) may identify more with the term 'positive play' than the term 'RG' which is frequently interpreted as being aimed at people with gambling problems, rather than all players.

    It is important in teaching adults to recognize the essential characteristics of adult learners and how these characteristics define their learning priorities and activities. The seven key premises and practices for teaching adults provide a good guide for those interested in helping adults learn. The emerging science of the neurobiology of learning provides powerful new insights into how learning occurs in the complex integrated neural network that characterizes the adult. Differentiation of the two types of thinking: System 1 (fast, intuitive, and, often, emotional) and System 2 (slower, deliberate, and logical). System 1 thinking helps explain the basis for quick decisions and reliance of humans on heuristics (or rules of thumb) that leads to the type of convenient thinking associated with errors of thinking and judgment. We now know that the learning experience has an objective location-in the temporal and parietal lobes-as persistent dynamic networks of neurons and neuronal connections. Learning is initially stored in transient working memory (relatively limited capacity and time frame) and then moved under the right conditions to more long-lasting/stable memory (with larger capacity) that is stored for future access and development. It is clear that memories are not static and are not destined, once developed, to forever remain as stable constructs; rather, memories are dynamic, always available for modulation and alteration, and heavily invested with context, emotion, and other operant factors. The framework for such neural networks involves new neuronal connections, enhanced neuronal synaptic transmission, and neuron generation. Ten key teaching and learning concepts derived from recent neurobiology studies on learning and memory are presented. As the neurobiology of learning is better defined, the basis for how adults best learn, and even the preferences they display, can be employed as the physiological foundation for our best methods to effectively teach

    Consistent evidence documents the negative impacts of family separation on refugee mental health and concerns for the welfare of distant family members and desire to reunite with family members as priorities for refugees postmigration. Less is known about refugees' emic perspectives on their experiences of family separation. Using mixed methods data from a community-based mental health intervention study, we found that family separation was a major source of distress for refugees and that it was experienced in a range of ways: as fear for family still in harm's way, as a feeling of helplessness, as cultural disruption, as the greatest source of distress since resettlement, and contributing to mixed emotions around resettlement. In addition to these qualitative findings, we used quantitative data to test the relative contribution of family separation to refugees' depression/anxiety symptoms, posttraumatic stress disorder (PTSD) symptoms, and psychological quality of life. Separation from a family member was significantly related to all 3 measures of mental health, and it explained significant additional variance in all 3 measures even after accounting for participants' overall level of trauma exposure. Relative to 26 other types of trauma exposure, family separation was 1 of only 2 traumatic experiences that explained additional variance in all 3 measures of mental health. Given the current global refugee crisis and the need for policies to address this large and growing issue, this research highlights the importance of considering the ways in which family separation impacts refugee mental health and policies and practices that could help ameliorate this ongoing stressor.

A new electronic autoinjection device has been designed to address these issues.Methods: Patients with relapsing multiple sclerosis currently receiving subcutaneous or intramuscular interferon beta-1a, interferon beta-1b, or glatiramer acetate completed an online questionnaire (July 4–25, 2008 that surveyed current injection practices, experiences with current injection methods, and impressions and appeal of the new device.Results: In total, 422 patients completed the survey, of whom 44% used autoinjectors, 43% prefilled syringes, and 13% syringes and vials; overall, 66% currently self-injected. Physical and psychological barriers to self-injection included difficulty with injections, needle phobia, and concerns over correct injection technique. Only 40% of respondents were “very satisfied” with their current injection method. The new electronic autoinjector was rated as “very appealing” by 65% of patients. The benefits of the new device included the ability to customize injection settings and to review dosing history.Conclusion: New technologies may help patients overcome physical and psychological barriers to self-injection. The combination of a reliable and flexible autoinjection device with dose-monitoring technology may improve communication between health care professionals and patients, and improve treatment adherence.Keywords: adherence, autoinjection, subcutaneous interferon beta-1a, multiple sclerosis

    : This study involves the assessment of the Bhutanese traditional medicine (BTM) which was integrated with the mainstream biomedicine in 1967 to provide primary health care services in the country. It caters to 20-30% of the daily out-patients within 49 traditional medicine units attached to 20 district modern hospitals and 29 Basic Health Units in the country. : This study presents the ethnopharmacological, ethnobotanical and the ethnoquality concepts in relation to mainstream Tibetan medicine and describes the current practices of BTM. : Experienced BTM practitioners (Drung-tshos and Smen-pas) were selected using a convenience sampling method and were interviewed using an open questionnaire followed by informal discussions. The corpus of BTM, Tibetan and scientific literature was obtained and the information on ethnopharmacological, ethnoquality and ethnobotanical concepts and current practices of BTM was extracted. : This study found that the BTM shares many similarities in terms of materia medica, pharmacopoeia and the principles and concepts of ethnopharmacology and ethnobotany with its mainstream Tibetan medicine. However, the resourceful Bhutanese Drung-tshos and Smen-pas have adapted this medical system based on the local language, culture, disease trend, health care needs and their familiarity with the locally available medicinal ingredients making it particular to the country. A number of notable distinctions observed in the current practices include a code of classification of diseases (only 79 of 404 types of disorders recognized), formulations (currently used only 103 of thousands formulation types), usage of medicinal plants (only 229 species of thousands described) and selected treatment procedures (golden needle and water therapy). This BTM was found to cater to 20-30% of daily out-patients visiting 49 modern hospitals and basic health units in the country. : The BTM has been evolved from the Tibetan medicine.

    2016-01-01

    On 5th December 2012, a scientific article reviewing a change in the feeding behaviour of the European catfish, one of the largest freshwater fish, was published in the American scientific journal, PLOS ONE, an open access journal, which also allows the mass publication of pictures and videos. Within a few days following the publication of this article, it was relayed by numerous web sites and generated a media craze. In this paper, we analyse the circulation of this scientific information in the sphere of Web-based media during the two months following its publication, by revealing the citation mechanisms of the original article and the logic of the Internet users participating in its diffusion. In addition, since the circulation of its informational content travelled beyond linguistic and geographical boundaries, we chose to compare the citation modalities and intertextual relationships of documents in the three countries where the article spread the most widely, namely: France, the United States and Great Britain. Even though our study shows that the media circulation of scientific papers operates in a traditional way, the intertextual analysis underlines the grand variety of participants (such as journalists, non-scientists, fishermen, technology enthusiasts and Internet users) involved in the diffusion of this information, each of them mobilizing different intertextual strategies, according to their various targets. They all transformed, reformulated and appropriated the scientific information according to their own, unique interests. This study also emphasizes the importance of journalistic websites as opinion relays. They were the first diffusers involved in spreading the information but this role was rarely acknowledged by the Internet users - through citations, for example. In contrast, we observed that amateurs' communities (communities of practices and communities of interest of fishermen or of buzz fans), which only became involved in a second temporal

    Full Text Available Biodiversity conservation is often measurable and achievable and has been reasonably successful within the boundaries of national parks. However, the concept of parks providing tangible benefits and hence being seen as ‘valuable’ to the majority of the nation has been more difficult to define, measure and, importantly, deliver on. This function has traditionally fallen under what is currently known as the People and Conservation Department, which has a rich history in South African National Parks (SANParks of change and adaptive learning in terms of defining core functions and associated management strategies, spanning from its original inception as the Information Services Department over 80 years ago. Learning from and in some cases, adapting to change, is evident throughout this broad scale national evolution of the department, from an initial focus on information sharing and education in the 1930s, to what we see today. This includes the primary focus areas of cultural resource management and indigenous knowledge, community relations, environmental education, awareness, youth outreach, interpretation and training. At a more local, park scale, there is a current drive to formalise the adaptive management and learning process for the people component of protected areas through the alignment of relevant project, programme and park objectives with those at a corporate or national level. Associated with this is an attempt to further align the associated monitoring, evaluation and reporting processes, thereby completing the formal adaptive management loops in order to facilitate and stimulate co-learning within and between relevant responsible departments within the organisation.Conservation implications: Benefit sharing through biodiversity conservation has been shown to be crucial for the long-term success of protected areas, but the practicalities of implementing this are thwart with challenges. Despite this, SANParks is attempting to

    2017-06-01

    The National Institutes of Health's Office of Behavioral and Social Sciences Research (OBSSR) recently released its Strategic Plan for 2017 to 2021. This plan highlights three scientific priorities: (1) improve the synergy of basic and applied behavioral and social sciences research, (2) enhance and promote the research infrastructure, methods, and measures needed to support a more cumulative and integrated approach to behavioral and social sciences research, and (3) facilitate the adoption of behavioral and social sciences research findings in health research and in practice. This commentary focuses on the challenges and opportunities to facilitate the adoption of research findings in health research and in practice. In addition to the ongoing NIH support for dissemination and implementation (D&I) research, we must address transformative challenges and opportunities such as better disseminating and implementing D&I research, merging research and practice, adopting more rigorous and diverse methods and measures for both D&I and clinical trials research, evaluating technological-based delivery of interventions, and transitioning from minimally adaptable intervention packages to planned adaptations rooted in behavior change principles. Beyond translation into practice and policy, the OBSSR Strategic Plan also highlights the need for translation of behavioral and social science findings into the broader biomedical research enterprise.

    Computer environments could support students in engaging in cognitive activities that are essential to scientific practice and to the understanding of the nature of scientific knowledge, but that are difficult to manage in science classrooms. The authors describe a design for a computer-based environment to assist students in conducting dialectical activities of constructing, comparing, and evaluating arguments for competing scientific theories. Their choice of activities and their design respond to educators' and theorists' criticisms of current science curricula. They give detailed specifications of portions of the environment.

    Scientific inquiry represents a multifaceted approach to explore and understand the natural world. Training students in the principles of scientific inquiry can help promote the scientific learning process as well as help students enhance their understanding of scientific research. Here, we report on the development and implementation of a learning module that introduces astrobiology students to the concepts of creative and scientific inquiry, as well as provide practical exercises to build critical thinking skills. The module contained three distinct components: (1) a creative inquiry activity designed to introduce concepts regarding the role of creativity in scientific inquiry; (2) guidelines to help astrobiology students formulate and self-assess questions regarding various scientific content and imagery; and (3) a practical exercise where students were allowed to watch a scientific presentation and practice their analytical skills. Pre- and post-course surveys were used to assess the students' perceptions regarding creative and scientific inquiry and whether this activity impacted their understanding of the scientific process. Survey results indicate that the exercise helped improve students' science skills by promoting awareness regarding the role of creativity in scientific inquiry and building their confidence in formulating and assessing scientific questions. Together, the module and survey results confirm the need to include such inquiry-based activities into the higher education classroom, thereby helping students hone their critical thinking and question asking skill set and facilitating their professional development in astrobiology.

    Beyond broad policy declarations, the implementation of ecological transition - which consists mainly in curbing consumption of energy and raw materials in our societies - requires substantial behavioural change at the collective, but also, quite obviously, the individual level. Yet, though there is general consensus around the principle of embarking on the path to transition, things get more complicated when it comes to changing our practices and habits. Can we act on individual behaviour and collective dynamics in respect of this particular aim of ecological transition, and, if so, how are we to go about it? Solange Martin and Albane Gaspard have examined this question for the French Environment and Energy Management Agency (ADEME) and offer us the fruit of their labours here. They show, for example, how the social and human sciences help to understand behaviour both at the individual level and in its collective dimensions, and they outline different possible lines of action to modify it. But, given the entanglement between various levels, it is essential, if we are to act effectively on behaviour, to combine approaches, tools and actors, and to analyse and understand social practices thoroughly before implementing political projects or measures

  20. What is Proof of Concept Research and how does it Generate Epistemic and Ethical Categories for Future Scientific Practice?

    Science.gov (United States)

    Kendig, Catherine Elizabeth

    2016-06-01

    "Proof of concept" is a phrase frequently used in descriptions of research sought in program announcements, in experimental studies, and in the marketing of new technologies. It is often coupled with either a short definition or none at all, its meaning assumed to be fully understood. This is problematic. As a phrase with potential implications for research and technology, its assumed meaning requires some analysis to avoid it becoming a descriptive category that refers to all things scientifically exciting. I provide a short analysis of proof of concept research and offer an example of it within synthetic biology. I suggest that not only are there activities that circumscribe new epistemological categories but there are also associated normative ethical categories or principles linked to the research. I examine these and provide an outline for an alternative ethical account to describe these activities that I refer to as "extended agency ethics". This view is used to explain how the type of research described as proof of concept also provides an attendant proof of principle that is the result of decision-making that extends across practitioners, their tools, techniques, and the problem solving activities of other research groups.

    Hypertension is an important public health issue in Zambia. Despite the need for early detection, treatment, and ongoing monitoring, there is little documented research on hypertension in Zambia. The study aims were to: 1) better understand risk factors for hypertension in urban and rural communities in Mongu and Limulunga Districts, Western Province; 2) identify current health practices for hypertension and prevention in these communities; and 3) explore intersections between culture and hypertension perceptions and practices for study participants. A mixed methods approach was used; 203 adults completed surveys including demographics, anthropometric measures, blood pressure (BP), physicial activity, diet, and salt intake at five health check stations. Two focus groups were conducted with rural and urban community members to better understand their perspectives on hypertension. The prevalence of hypertension was 32.8% for survey participants. A further 24.6% had pre-hypertension. The mean total weight of salt added to food was nearly double the WHO recommendation with women adding significantly more salt to food than men. Significant differences in waist circumference were observed between men and women with men at low risk and women at substantialy high risk. In focus groups, participants cited westernized diets, lack of physical activity, stress, psychological factors, and urbanization as causative factors for hypertension. Participants lacked understanding of BP medications, healthy lifestyles, adherence to treatment, and ongoing monitoring. Focus group participants mentioned challenges in obtaining treatment for hypertension and desired to be active contributors in creating solutions. They recommended that government priorize hypertension initiatives that increase access to health education to reduce risk, enhance early detection, and support lifestyle changes and medication adherence. Our findings suggest that policy-makers need to engage communities more

    Full Text Available Indigenous participation in land-based practices such as hunting, fishing, ceremony, and land care has a long history. In recent years, researchers and policy makers have advocated the benefits of these practices for both Indigenous people and the places they live. However, there have also been documented risks associated with participation in these activities. Environmental change brought about by shifts in land use, climate changes, and the accumulation of contaminants in the food chain sit alongside equally rapid shifts in social, economic and cultural circumstances, preferences and practices. To date, the literature has not offered a wide-ranging review of the available cross-disciplinary or cross-ecozone evidence for these intersecting benefits and risks, for both human and environmental health and wellbeing. By utilising hunting as a case study, this paper seeks to fill part of that gap through a transdisciplinary meta-analysis of the international literature exploring the ways in which Indigenous participation in land-based practices and human-environmental health have been studied, where the current gaps are, and how these findings could be used to inform research and policy. The result is an intriguing summary of disparate research that highlights the patchwork of contradictory understandings, and uneven regional emphasis, that have been documented. A new model was subsequently developed that facilitates a more in-depth consideration of these complex issues within local-global scale considerations. These findings challenge the bounded disciplinary and geographic spaces in which much of this work has occurred to date, and opens a dialogue to consider the importance of approaching these issues holistically.

    The NSF-supported “AstroCom NYC” program, a collaboration of the City University of New York and the American Museum of Natural History (AMNH), has developed and offers hands-on workshops to undergraduate faculty on teaching science thought and practices. These professional development workshops emphasize a curriculum and pedagogical strategies that uses computers and other digital devices in a laboratory environment to teach students fundamental topics, including: proportional reasoning, control of variables thinking, experimental design, hypothesis testing, reasoning with data, and drawing conclusions from graphical displays. Topics addressed here are rarely taught in-depth during the formal undergraduate years and are frequently learned only after several apprenticeship research experiences. The goal of these workshops is to provide working and future faculty with an interactive experience in science learning and teaching using modern technological tools.

    The caries lesion, the most commonly observed sign of dental caries disease, is the cumulative result of an imbalance in the dynamic demineralization and remineralization process that causes a net mineral loss over time. A classification system to categorize the location, site of origin, extent, and when possible, activity level of caries lesions consistently over time is necessary to determine which clinical treatments and therapeutic interventions are appropriate to control and treat these lesions. In 2008, the American Dental Association (ADA) convened a group of experts to develop an easy-to-implement caries classification system. The ADA Council on Scientific Affairs subsequently compiled information from these discussions to create the ADA Caries Classification System (CCS) presented in this article. The ADA CCS offers clinicians the capability to capture the spectrum of caries disease presentations ranging from clinically unaffected (sound) tooth structure to noncavitated initial lesions to extensively cavitated advanced lesions. The ADA CCS supports a broad range of clinical management options necessary to treat both noncavitated and cavitated caries lesions. The ADA CCS is available for implementation in clinical practice to evaluate its usability, reliability, and validity. Feedback from clinical practitioners and researchers will allow system improvement. Use of the ADA CCS will offer standardized data that can be used to improve the scientific rationale for the treatment of all stages of caries disease. Copyright © 2015 American Dental Association.

    Full text: In the report a question on necessity of practical development of a method of inspection of radiating fields, adapted to a nature of pollution is put. 50-year study of radionuclides pollution, dropping out from atmosphere after nuclear tests or failures, have shown non-perspective of traditional techniques of inspection of a radiating conditions on large territories. The detailed measurements covering surface without gaps are very expensive, and use of a unloaded grid requires interpolation irregular mosaic structure. Detection Fractal structure at the analysis Chernobyl losses and pollution of fragments of Semipalatinsk test nuclear site specify necessity of the account of self-similar properties of pollution in philosophy of measurement. For realization of potential opportunities Fractal field the special circuit of measurements, distinguished from, is required standard. Fractal approach requires shooting with system of crossed vicinities on chosen detailed platforms, making a rather small part of surveyed territory. These data will allow to reveal scale laws, which are universal in a significant range of scales. Using scaling of small platforms, it is possible to receive correct estimation of structure of pollution of large territories. The stated above reasons are based on our experiments on fractal approach to the analysis of continuous shooting (aero-scale shooting of scale 1:5000) in a zone of Semipalatinsk test site on three platforms by the sizes on 1000x400 m 2 . Our results specify necessity revision almost of all conclusions, received earlier on the basis of traditional techniques

    Wet cupping was used in the nineteenth century for treatment of patients in the United Kingdom (UK) by a few experienced practitioners. Revival Hijama use by practitioners in the UK in recent years has been observed as well as interest from the public, with developments of specific certified training programmes, established businesses providing tailored Hijama therapy Clinical Waste disposal services, provisions of insurance cover, involvement of medical professionals and membership with the General Regulatory Council for Complementary Therapies (GRCCT). However, there has also been noted that there is not much in the way of guidance or regulation. Therefore, we would like to initiate some communication and understanding of Hijama (wet cupping) to benefit medical professionals, discussing recent research undertaken as a basis for potentially more in the future (evidence-based practice), in the likely event that a patient might request to be referred for this therapy during a consultation.

    Statistics and Analysis of Scientific Data covers the foundations of probability theory and statistics, and a number of numerical and analytical methods that are essential for the present-day analyst of scientific data. Topics covered include probability theory, distribution functions of statistics, fits to two-dimensional datasheets and parameter estimation, Monte Carlo methods and Markov chains. Equal attention is paid to the theory and its practical application, and results from classic experiments in various fields are used to illustrate the importance of statistics in the analysis of scientific data. The main pedagogical method is a theory-then-application approach, where emphasis is placed first on a sound understanding of the underlying theory of a topic, which becomes the basis for an efficient and proactive use of the material for practical applications. The level is appropriate for undergraduates and beginning graduate students, and as a reference for the experienced researcher. Basic calculus is us...

    To characterize leadership curricula in undergraduate medical education as a first step toward understanding best practices in leadership education. The authors systematically searched the PubMed, Education Resources Information Center, Academic Search Complete, and Education Full Text databases for peer-reviewed English-language articles published 1980-2014 describing curricula with interventions to teach medical students leadership skills. They characterized educational settings, curricular format, and learner and instructor types. They assessed effectiveness and quality of evidence using five-point scales adapted from Kirkpatrick's four-level training evaluation model (scale: 0-4) and a Best Evidence Medical Education guide (scale: 1-5), respectively. They classified leadership skills taught into the five Medical Leadership Competency Framework (MLCF) domains. Twenty articles describing 24 curricula met inclusion criteria. The majority of curricula (17; 71%) were longitudinal, delivered over periods of one semester to four years. The most common setting was the classroom (12; 50%). Curricula were frequently provided to both preclinical and clinical students (11; 46%); many (9; 28%) employed clinical faculty as instructors. The majority (19; 79%) addressed at least three MLCF domains; most common were working with others (21; 88%) and managing services (18; 75%). The median effectiveness score was 1.5, and the median quality of evidence score was 2. Most studies did not demonstrate changes in student behavior or quantifiable results. Aligning leadership curricula with competency models, such as the MLCF, would create opportunities to standardize evaluation of outcomes, leading to better measurement of student competency and a better understanding of best practices.

  12. Salt, time, and metaphor: examining norms in scientific culture

    As has been widely discussed, the National Research Council's (NRC) current policy in United States education advocates supporting students toward acquiring skills to engage in scientific practices. NRC policy also suggests that supporting students in the practices of science may require different approaches than what is required for supporting student engagement with scientific content. Further, acquiring skills in scientific practices is not limited to gaining proficiency in utilizing tools that support scientific inquiry: students must also understand how to interpret information generated from such tools. These tools of scientific practices are embedded within scientific culture, which from Sewell's perspective, is comprised of both practice and semiotic code (symbols and meanings). To become scientifically literate students must learn to utilize this code in practice. Author Germà Garcia-Belmonte identified one example of learning to utilize the semiotic code in scientific practice and considers challenges faced by undergraduate physics and engineering students within that context. Garcia-Belmonte observes students struggle to interpret symbols and meaning (the visual display generated) while engaging in practice (utilizing an oscilloscope) and posits that two, culturally bound, competing, linguistic metaphors of time may be the cause. Ultimately, however, the author does not explore beyond hypotheses. Although his theory may be correct, the paper serves as a reminder of the responsibility we have to students. As educators, it is useful and beneficial to make observations and develop theories surrounding why our students struggle. However, in addition to theorizing on why, for example, a particular scientific norm might present challenges for our students, we must remain mindful that challenges may not be uniform and may vary considerably according to students' culture(s). Engaging with students and soliciting specific information regarding the challenges

    There is increasing recognition of Indigenous perspectives from various parts of the world in relation to storytelling, research and its effects on practice. The recent emergence of storytelling or yarning as a research method in Australian Aboriginal and Torres Strait Island studies and other Indigenous peoples of the world is gaining momentum. Narratives, stories, storytelling and yarning are emerging methods in research and has wide ranging potential to shape conventional research discourse making research more meaningful and accessible for researchers. In this paper we argue for the importance of Indigenous research methods and Indigenous method(ology), within collaborative respectful partnerships with non-Indigenous researchers. It is imperative to take these challenging steps together towards better outcomes for Indigenous people and their communities. In the Australian context we as researchers cannot afford to allow the gap between Aboriginal and Torres Strait Islanders and mainstream Australia health outcomes to grow even wider. One such pathway is the inclusion of Aboriginal storytelling or yarning from an Aboriginal and Torres Strait perspective within Indigenous and non-Indigenous research paradigms. Utilising Aboriginal storytelling or yarning will provide deeper understanding; complementing a two-way research paradigm for collaborative research. Furthermore, it has significant social implications for research and clinical practice amongst Indigenous populations; thus complementing the biomedical medical paradigm.

    Full Text Available This is the first in a series of articles reporting on a study of researcher data management practices and data services at the University of Vermont. The objective of this article is to report on the first qualitative phase of an exploratory sequential mixed methods research design focused on researcher data management practices and related institutional research data services. The aim of this study is to understand data management behaviors of faculty at the University of Vermont (UVM, a higher-research activity Research University, in order to guide the development of campus research data management services. The population of study was all faculty who received National Science Foundation (NSF grants between 2011 and 2014 who were required to submit a data management plan (DMP; qualitative data was collected in two forms: (1 semi-structured interviews and (2 document analysis of data management plans. From a population of 47 researchers, six were included in the interview sample, representing a broad range of disciplines and NSF Directorates, and 35 data management plans were analyzed. Three major themes were identified through triangulation of qualitative data sources: data management activities, including data dissemination and data sharing; institutional research support and infrastructure barriers; and perceptions of data management plans and attitudes towards data management planning. The themes articulated in this article will be used to design a survey for the second quantitative phase of the study, which will aim to more broadly generalize data management activities at UVM across all disciplines.

  15. Strategic plan for scientific computing

    Computing technology continues to undergo rapid and dramatic changes. Technological improvements in both hardware and software continue to permit analysts to model problems much more realistically than heretofore practicable. New visualization technologies vastly increase our ability to understand the results of those complex models. The mission of SRS is also undergoing very rapid change as a result of international events. While the typical demands of reactor oriented calculations may decline, environmental regulations require us to study new classes of problems in ever increasing detail. Hence, the computational workload is actually increasing rapidly. At the same time, the budget constraints demand a continued increase in cost effectiveness of scientific computing. A comprehensive strategy for scientific computing is required to adapt to these changes and still produce timely solutions to ensure continued safe operation of SRS facilities. An important goal of this strategy is to ensure that productivity gains available with new systems and technologies are truly achieved.

The study aims to understand data management activities and challenges of faculty at the University of Vermont (UVM, a higher research activity Research University, in order to develop appropriate research data services (RDS. Data was collected via a survey, built on themes from the initial qualitative data analysis from the first phase of this study. The survey was distributed to a nonrandom census sample of full-time UVM faculty and researchers (P=1,190; from this population, a total of 319 participants completed the survey for a 26.8% response rate. The survey collected information on five dimensions of data management: data management activities; data management plans; data management challenges; data management support; and attitudes and behaviors towards data management planning. Frequencies, cross tabulations, and chi-square tests of independence were calculated using demographic variables including gender, rank, college, and discipline. Results from the analysis provide a snapshot of research data management activities at UVM, including types of data collected, use of metadata, short- and long-term storage of data, and data sharing practices. The survey identified key challenges to data management, including data description (metadata and sharing data with others; this latter challenge is particular impacted by confidentiality issues and lack of time, personnel, and infrastructure to make data available. Faculty also provided insight to RDS that they think UVM should support, as well as RDS they were personally interested in. Data from this study will be integrated with data from the

    Voluntary reporting of incidents is a common approach for improving patient safety. Reporting behaviors may vary because of different frames within and across professions, where frames are templates that individuals hold and that guide interpretation of events. Our objectives were to investigate frames of physicians and nurses who report into a voluntary incident reporting system as well as to understand enablers and inhibitors of self-reporting and peer reporting. This is a qualitative case study-confidential in-depth interviews with physicians and nurses in General Internal Medicine in a Canadian tertiary care hospital. Frames that health care practitioners use in their reporting practices serve as enablers and inhibitors for self-reporting and peer reporting. Frames that inhibit reporting are shared by physicians and nurses, such as the fear of blame frame regarding self-reporting and the tattletale frame regarding peer reporting. These frames are underpinned by a focus on the individual, despite the organizational message of reporting for learning. A learning frame is an enabler to incident reporting. Viewing the objective of voluntary incident reporting as learning allows practitioners to depersonalize incident reporting. The focus becomes preventing recurrence and not the individual reporting or reported on. Physicians and nurses use various frames that bound their views of self and peer incident reporting-further progress should incorporate an understanding of these deep-seated views and beliefs.

    Full Text Available Rapid expansion of commercial horticulture production and related activities contribute to declining surface water quality. The study sought to understand the impacts on select rivers in Laikipia and Meru, production hotspots. The specific aims were (1 to identify prevailing surface water quality by examining variations of 14 physico-chemical parameters, and (2 to categorize measured surface water quality parameters into land use types highlighting potential pollutant source processes. Water samples were collected in July and August 2013 along 14 rivers in the study area. The data were analyzed using principal component analysis (PCA and discriminant analysis (DA. Principal components (PCs explained 70% of the observed total variability of water quality, indicating a prevalence of heavy metal traces (cadmium, phosphate, and zinc. These were linked to the rigorous use of phosphate fertilizers and copper-based agrochemicals in intensive farming. DA provided four significant (p < 0.05 discriminant functions, with 89.5% correct assignment enabling the association of land use with observed water quality. Concentrations of dissolved solids, electro-conductivity, and salinity spiked at locations with intensive small-scale and large-scale horticulture. Understanding the impacts of intensive commercial horticulture and land use practices on water quality is critical to formulating ecologically sound watershed management and pollution abatement plans.

  19. Scientific Eschatology

    Noyes, H

    2005-03-18

    The future evolution of the universe suggested by the cosmological model proposed earlier at this meeting by the authors is explored. The fundamental role played by the positive ''cosmological constant'' is emphasized. Dyson's 1979 paper entitled ''Time Without End'' is briefly reviewed. His most optimistic scenario requires that the universe be geometrically open and that biology is structural in the sense that the current complexity of human society can be reproduced by scaling up its (quantum mechanical) structure to arbitrary size. If the recently measured ''cosmological constant'' is indeed a fundamental constant of nature, then Dyson's scenario is, for various reasons, ruled out by the finite (De Sitter) horizon due to exponential expansion of the resulting space. However, the finite temperature of that horizon does open other interesting options. If, as is suggested by the cosmology under consideration, the current exponential expansion of the universe is due to a phase transition which fixes a physical boundary condition during the early radiation dominated era, the behavior of the universe after the relevant scale factor crosses the De Sitter radius opens up still other possibilities. The relevance of Martin Rees' apocalyptic eschatology recently presented in his book ''Our Final Hour'' is mentioned. It is concluded that even for the far future, whether or not cultural and scientific descendants of the current epoch will play a role in it, an understanding (sadly, currently lacking) of community and political evolution and control is essential for a preliminary treatment of what could be even vaguely called scientific eschatology.

    Inquiry-based teaching is considered as contributing to content-related, procedural, and epistemic learning goals of science education. In this study, a quasi-experimental research design was utilized to investigate to what extent embedding inquiry activities in an explicit and an implicit instructional approach fosters students' ability to engage in three practices of scientific investigation (POSI): (1) formulating questions and hypotheses, (2) planning investigations, (3) analyzing and interpreting data. Both approaches were implemented in a classroom-based intervention conducted in a German upper secondary school (N = 222). Students' procedural knowledge of the three POSI was assessed with a paper-pencil test prior and post to the intervention, their content knowledge and dispositional factors (e.g., cognitive abilities) were gathered once. Results show that not only explicit but also implicit instruction fosters students' knowledge of POSI. While overall explicit instruction was found to be more effective, the findings indicate that the effectiveness depends considerably on the practice addressed. Moreover, findings suggest that both approaches were equally beneficial for all students regardless of their prior content knowledge and their prior procedural knowledge of POSI. Potential conditions for the success of explicit and implicit approaches as well as implications for instruction on POSI in science classrooms and for future research are discussed.
