    Liehr, Patricia; Smith, Mary Jane

    This replication and critique addresses ongoing development and use of middle range theory since considering this body of nursing knowledge 18 years ago. Middle range theory is appreciated as essential to the structure of nursing knowledge. Nine middle range theories that demonstrate ongoing use by the theory authors are analyzed using the criteria of theory name, theory generation, disciplinary perspective, theory model, practice use and research use. Critique conclusions indicate the importance of staying with the theory over time, naming and development consistent with the disciplinary perspective, movement to an empirical level, and bringing middle range theory to the interdisciplinary table.

  5. Heuristic thinking: interdisciplinary perspectives on medical error

    Directory of Open Access Journals (Sweden)

    Full Text Available Approximately 43 million adverse events occur across the globe each year at a cost of at least 23 million disability-adjusted life years and $132 billion in excess health care spending, ranking this safety burden among the top 10 medical causes of disability in the world.1 These findings are likely to be an understatement of the actual severity of the problem, given that the numbers merely reflect seven types of adverse events and completely neglect ambulatory care, and of course they only cover reported incidents. Furthermore, they do not include statistics on children and incidents from India and China, which host more than a third of the world’s population. Best estimates imply that about two thirds of these incidents are preventable. Thus, from a public health perspective, medical errors are a seri- ous global health burden, in fact ahead of high-profile health problems like AIDS and cancer. Interventions to date have not reduced medical errors to satisfactory rates. Even today, far too often, hand hygiene is not practiced properly (even in developed countries, surgical procedures take place in underequipped operating theaters, and checklists are missing or remain uncompleted. The healthcare system seems to be failing in managing its errors − it is costing too much, and the complexity of care causes severe safety hazards that too often harm rather than help patients. In response to this evolving discussion, the International Society for Quality in Healthcare recently nominated an Innovations Team that is now developing new strategies. One of the emerging themes is that the medical field cannot resolve this problem on its own. Instead, interdisciplinary collaborations are needed to advance effective, evidence-based interventions that will eventually result in competent changes. In March 2013, the Institute of Communication and Health at the University of Lugano organized a conference on Communicating Medical Error (COME 2013 in

    2017-12-01

    Full Text Available Interdisciplinary (i.e., university-wide programming and disciplinary (i.e., programming open to participants from one college or department teaching development programs for graduate students have been used for many years in higher education. Currently, research on the benefits of these teaching models remains scant in terms of a contextualized understanding, and empirical studies are needed. The purpose of this study was to determine graduate students’ perspectives related to interdisciplinary and disciplinary teaching and learning experiences. Two online surveys were used: a quantitative survey and a qualitative follow-up survey. Three participatory focus groups were also conducted to allow for further in-depth exploration in both an interdisciplinary and disciplinary group setting that represented seven distinct colleges. Statistical and thematic analyses were conducted with survey responses, and thematic analyses were conducted on focus group data. Similar themes emerged from the survey and focus group data identifying perceived benefits of participation in either interdisciplinary or disciplinary teaching development. Respondents’ perceived benefits were related to: (a becoming a better teacher; (b social learning; and (c that while the perceived benefits of the models vary, the outcomes of both experiences are shared. The lived experiences of these graduate students expand the characterization of interdisciplinary and disciplinary programming. This study points to the need for graduate student programs—specifically teaching development offered by educational development units—to provide both interdisciplinary and disciplinary teaching development opportunities that achieve a blend of benefits for learners.

    Full Text Available The paper examines the abstract genre from the perspectives of English for Specific Purposes (ESP practitioners and information professionals. It aims to determine specific interdisciplinary interests in the abstract, and to explore areas of collaboration in terms of research and pedagogical practices. A focus group (FG comprising information professionals from the Division of Information Studies, Nanyang Technological University, Singapore, convened for a discussion on the subject of abstracts and abstracting. Two major issues that have significant implications for ESP practices emerged during the discussion. While differences in terms of approach to and objectives of the abstract genre are apparent between information professionals and language professionals, the demands for specific cognitive processes involved in abstracting proved to be similar. This area of similarity provides grounds for awareness raising and collaboration between the two disciplines. While ESP practitioners need to consider adding the dimension of information science to the rhetorical and linguistic scaffolding that they have been providing to novice-writers, information professionals can contribute useful insights about the qualities of abstracts that have the greatest impact in meeting the end-users' needs in information search.

    Looking at Open Science and Open Data from a broad perspective. This is the idea behind "Scientific data sharing: an interdisciplinary workshop", an initiative designed to foster dialogue between scholars from different scientific domains which was organized by the Istituto Italiano di Antropologia in Anagni, Italy, 2-4 September 2013.We here report summaries of the presentations and discussions at the meeting. They deal with four sets of issues: (i) setting a common framework, a general discussion of open data principles, values and opportunities; (ii) insights into scientific practices, a view of the way in which the open data movement is developing in a variety of scientific domains (biology, psychology, epidemiology and archaeology); (iii) a case study of human genomics, which was a trail-blazer in data sharing, and which encapsulates the tension that can occur between large-scale data sharing and one of the boundaries of openness, the protection of individual data; (iv) open science and the public, based on a round table discussion about the public communication of science and the societal implications of open science. There were three proposals for the planning of further interdisciplinary initiatives on open science. Firstly, there is a need to integrate top-down initiatives by governments, institutions and journals with bottom-up approaches from the scientific community. Secondly, more should be done to popularize the societal benefits of open science, not only in providing the evidence needed by citizens to draw their own conclusions on scientific issues that are of concern to them, but also explaining the direct benefits of data sharing in areas such as the control of infectious disease. Finally, introducing arguments from social sciences and humanities in the educational dissemination of open data may help students become more profoundly engaged with Open Science and look at science from a broader perspective.

    2017-06-01

    Games for health (G4H) aim to improve health outcomes and encourage behavior change. While existing theoretical frameworks describe features of both games and health interventions, there has been limited systematic investigation into how disciplinary and interdisciplinary stakeholders understand design features in G4H. We recruited 18 experts from the fields of game design, behavioral health, and games for health, and prompted them with 16 sample games. Applying methods including open card sorting and triading, we elicited themes and features (e.g., real-world interaction, game mechanics) around G4H. We found evidence of conceptual differences suggesting that a G4H perspective is not simply the sum of game and health perspectives. At the same time, we found evidence of convergence in stakeholder views, including areas where game experts provided insights about health and vice versa. We discuss how this work can be applied to provide conceptual tools, improve the G4H design process, and guide approaches to encoding G4H-related data for large-scale empirical analysis.

    Dietary assessment can be challenging for many reasons, including the wide variety of foods, eating patterns and nutrients to be considered. In team-based primary care practice, various disciplines may be involved in assessing diet. Electronic-based dietary assessment (e-DA) instruments available now through mobile apps or websites can potentially facilitate dietary assessment. Providers views of facilitators and barriers related to e-DA instruments and their recommendations for improvement can inform the further development of these tools. The objective of this study was to explore provider perspectives on e-DA tools in mobile apps and websites. The exploratory sequential mixed methods design included interdisciplinary focus groups followed by a web-based survey sent to Family Health Teams throughout Ontario, Canada. Descriptive and bivariate analyses were completed. Focus group transcripts contributed to web-survey content, while interpretive themes added depth and context. 11 focus groups with 50 providers revealed varying perspectives on the use of e-DA for: 1) improving patients' eating habits; 2) improving the quality of dietary assessment; and, 3) integrating e-DA into the care process. In the web-survey 191 respondents from nine disciplines in 73 FHTs completed the survey. Dietitians reported greater use of e-DA than other providers (63% vs.19%; p = .000) respectively. There was strong interest among disciplines in the use of e-DA tools for the management of obesity, diabetes and heart disease, especially for patient self-monitoring. Barriers identified were: patients' lack of comfort with using technology, misinterpretation of e-DA results by patients, time and education for providers to interpret results, and time for providers to offer counselling. e-DA tools in mobile apps and websites may improve dietary counselling over time. Addressing the identified facilitators and barriers can potentially promote the uptake of e-DA into clinical practice.

    The calibration device for a wide range monitor according to the present invention can continuously calibrate the entire counting regions of a wide range monitor. The wide range monitor detect the reactor power in the neutron source region by means of a pulse counting method and detects the reactor power in the intermediate region by means of a cambell method. A calibration signal outputting means is disposed for continuously outputting, as such calibration signals, pulse number varying signals in which the number of pulses per unit time varies depending on the reactor power in the neutron source region to be simulated and amplitude square means varying signal in which the mean square value of amplitude varies depending on the reactor power in the intermediate region to be simulated. By using both of the calibration signals, calibration can be conducted for the nuclear reactor power in the neutron source region and the intermediate region even if the calibration is made over two regions, further, calibration for the period present over the two region can be conducted easily as well.

  6. Resilience Thinking as an Interdisciplinary Guiding Principle for Energy System Transitions

    Directory of Open Access Journals (Sweden)

    Frauke Wiese

    2016-09-01

    Full Text Available Resource usage and environmental consequences of most current energy systems exceed planetary boundaries. The transition to sustainable energy systems is accompanied by a multitude of research methods, as energy systems are complex structures of technical, economical, social and ecological interactions. The description of different discipline’s perspectives in this paper show that a more mutual understanding between disciplines of their respective focus is necessary as they partly create internally competitive views arising from differing emphasis of connected matters. The purpose of this paper is to present a framework for interdisciplinary proceeding in a complex energy system transition process. Resilience thinking is chosen as a core concept for a more holistic view on sustainable energy system development. It is shown that it is already widely used in different disciplines connected to energy system research and is especially suitable due to its wide application across disciplines. The seven principles of resilience thinking (maintain redundancy and diversity, manage connectivity, manage slow variables and feedback, foster complex adaptive systems thinking, encourage learning, broaden participation, and promote polycentric governance systems are chosen as the basis for a procedure that can be utilized to increase the interdisciplinary perspectives of energy system transitions. For energy transition processes based on scenario development, backcasting and pathway definition, resilience thinking principles are used to assess the resilience of the target energy system, the pathway resilience and the design of the scenario process with respect to the probability of a resilient outcome. The described procedure consisting of questions and parameters can be applied as a first attempt for a resilience assessment of energy transition processes. The perspective of resilience in sustainable energy systems strengthens the importance of diversity

    Evacuating a city is a complex problem that involves issues of governance, preparedness education, warning, information sharing, population dynamics, resilience and recovery. As natural and anthropogenic threats to cities grow, it is an increasingly pressing problem for policy makers and practitioners.   The book is the result of a unique interdisciplinary collaboration between researchers in the physical and social sciences to consider how an interdisciplinary approach can help plan for large scale evacuations.  It draws on perspectives from physics, mathematics, organisation theory, economics, sociology and education.  Importantly it goes beyond disciplinary boundaries and considers how interdisciplinary methods are necessary to approach a complex problem involving human actors and increasingly complex communications and transportation infrastructures.   Using real world case studies and modelling the book considers new approaches to evacuation dynamics.  It addresses questions of complexity, not only ...

    Quintel, M; Kumle, B

    2011-04-01

    Modern processes in the organization in German hospitals are decisive to the development of emergency departments and as these represent the interface between outpatient and inpatient care, they have been identified as a strategic success factor. In larger hospitals emergency departments are generally run as independent units with their own management. The growing number of patients in emergency rooms each year demonstrates the future importance of these structures and successful hospital management has to face and handle this challenge. Clear job profiles for the leadership, staff members and structures of these units are needed. This article highlights the requirements for these structures from the perspective of the German Interdisciplinary Association of Critical Care Medicine (DIVI).

    2004-01-01

    Wide range survey meters (1μSv/h -10 Sv/h) with the detector(s) mounted at the end of a two-to-four meter-long extendable tube are widely used for radiation protection survey of difficult to reach locations and high dose rate areas, The commercially available survey meters of this type use two GM counters to cover a wide range of dose rate measurement. A new micro-controller based wide range survey meter using two Si diode detectors has been developed. The use of solid state detectors in the survey meter has a number of advantages like low power consumption, lighter battery powered detector probe, elimination of high voltage for the operation of the detectors, etc. The design uses infrared communication between the probe and the readout unit through a light-weight collapsible extension tube for high reliability. The design details and features are discussed in detail. (author)

  11. Health economic choices in old age: interdisciplinary perspectives on economic decisions and the aging mind.

    Science.gov (United States)

    Nielsen, Lisbeth; Phillips, John W R

    2008-01-01

    This chapter offers an integrative review of psychological and neurobiological differences between younger and older adults that might impact economic behavior. Focusing on key health economic challenges facing the elderly, it offers perspectives on how these psychological and neurobiological factors may influence decision-making over the life course and considers future interdisciplinary research directions. We review relevant literature from three domains that are essential for developing a comprehensive science of decision-making and economic behavior in aging (psychology, neuroscience, and economics), consider implications for prescription drug coverage and long-term care (LTC) insurance, and highlight future research directions. Older adults face many complex economic decisions that directly affect their health and well-being, including LTC insurance, prescription drug plans, and end of life care. Economic research suggests that many older Americans are not making cost-effective and economically rational decisions. While economic models provide insight into some of the financial incentives associated with these decisions, they typically do not consider the roles of cognition and affect in decision-making. Research has established that older age is associated with predictable declines in many cognitive functions and evidence is accumulating that distinct social motives and affect-processing profiles emerge in older age. It is unknown how these age differences impact the economic behaviors of older people and implies opportunities for path-breaking interdisciplinary research. Our chapter looks to develop interdisciplinary research to better understand the causes and consequences of age-related changes in economic decision-making and guide interventions to improve public programs and overall social welfare.

  12. Combining interdisciplinary and International Medical Graduate perspectives to teach clinical and ethical communication using multimedia.

    Science.gov (United States)

    Woodward-Kron, Robyn; Flynn, Eleanor; Delany, Clare

    2011-01-01

    In Australia, international medical graduates (IMGs) play a crucial role in addressing workforce shortages in healthcare. Their ability to deliver safe and effective healthcare in an unfamiliar cultural setting is intrinsically tied to effective communication. Hospital-based medical clinical educators, who play an important role in providing communication training to IMGs, would benefit from practical resources and an understanding of the relevant pedagogies to address these issues in their teaching. This paper examines the nature of an interdisciplinary collaboration to develop multimedia resources for teaching clinical and ethical communication to IMGs. We describe the processes and dynamics of the collaboration, and outline the methodologies from applied linguistics, medical education, and health ethics that we drew upon. The multimedia consist of three video clips of challenging communication scenarios as well as experienced IMGs talking about communication and ethics. The multimedia are supported by teaching guidelines that address relevant disciplinary concerns of the three areas of collaboration. In the paper's discussion we point out the pre-conditions that facilitated the interdisciplinary collaboration. We propose that such collaborative approaches between the disciplines and participants can provide new perspectives to address the multifaceted challenges of clinical teaching and practice.

    2013-01-01

    Complexity Science and Chaos Theory are fascinating areas of scientific research with wide-ranging applications.  The interdisciplinary nature and ubiquity of complexity and chaos are features that provides scientists with a motivation to pursue general theoretical tools and frameworks. Complex systems give rise to emergent behaviors, which in turn produce novel and interesting phenomena in science, engineering, as well as in the socio-economic sciences. The aim of all Symposia on Chaos and Complex Systems (CCS) is to bring together scientists, engineers, economists and social scientists, and to discuss the latest insights and results obtained in the area of corresponding nonlinear-system complex (chaotic) behavior. Especially for the “4th International Interdisciplinary Chaos Symposium on Chaos and Complex Systems,” which took place April 29th to May 2nd, 2012 in Antalya, Turkey, the scope of the symposium had been further enlarged so as to encompass the presentation of work from circuits to econophysic...

  15. Rawls’s Wide Reflective Equilibrium as a Method for Engaged Interdisciplinary Collaboration

    Science.gov (United States)

    Taebi, Behnam

    2017-01-01

    The introduction of new technologies in society is sometimes met with public resistance. Supported by public policy calls for “upstream engagement” and “responsible innovation,” recent years have seen a notable rise in attempts to attune research and innovation processes to societal needs, so that stakeholders’ concerns are taken into account in the design phase of technology. Both within the social sciences and in the ethics of technology, we see many interdisciplinary collaborations being initiated that aim to address tensions between various normative expectations about science and engineering and the actual outcomes. However, despite pleas to integrate social science research into the ethics of technology, effective normative models for assessing technologies are still scarce. Rawls’s wide reflective equilibrium (WRE) is often mentioned as a promising approach to integrate insights from the social sciences in the normative analysis of concrete cases, but an in-depth discussion of how this would work in practice is still lacking. In this article, we explore to what extent the WRE method can be used in the context of technology development. Using cases in engineering and technology development, we discuss three issues that are currently neglected in the applied ethics literature on WRE. The first issue concerns the operationalization of abstract background theories to moral principles. The second issue concerns the inclusiveness of the method and the demand for openness. The third issue is how to establish whether or not an equilibrium has been reached. These issues should be taken into account when applying the methods to real-world cases involving technological risks. Applying the WRE method in the context of engaged interdisciplinary collaboration requires sensitivity for issues of power and representativeness to properly deal with the dynamics between the technical and normative researchers involved as well as society at large.

    An interdisciplinary approach is often described as a valuable strategy to assist in overcoming the existing and emerging challenges to water resource management. The development of educational approaches to instil a culture of interdisciplinarity in the future generation of water resource professionals will help to meet this strategic need. The Vienna Doctoral Programme on Water Resource Systems demonstrates how the adoption of an interdisciplinary education framework has been applied to a graduate programme in the water sciences. The interdisciplinary approach aims to provide doctoral research students with an understanding of the wide spectrum of processes relevant to water resource systems. This will enable them to bring together a range of ideas, strategies and methods to their current research and future careers. The education programme also aims to teach the softer skills required for successful interdisciplinary work such as the ability to communicate clearly with non-specialist professionals and the capacity to listen to and accommodate suggestions from experts in different disciplines, which have often not traditionally been grouped together. The Vienna Doctoral Programme achieves these aims through teaching an appreciation for a wide variety of approaches including laboratory analysis, field studies and numerical methods across the fields of hydrology, remote sensing, hydrogeology, structural mechanics, microbiology, water quality and resource management. Teaching takes the form of a detailed study programme on topics such as socio-economic concepts, resource and river basin management, modelling and simulation methods, health related water quality targets, urban water management, spatial data from remote sensing and basics for stochastic mechanics. Courses are also held by internationally recognised top scientists, and a guest scientist seminar series allows doctoral researchers to profit from the expertise of senior researchers from around the world

    2015-01-01

    Interdisciplinarity has seemingly become a paradigm for modern and meaningful research. Clearly, the interdisciplinary modus of deliberation enables to unfold relevant but quite different disciplinary perspectives to the reflection of broader scientific questions or societal problems. However, whether the comprehensive results of interdisciplinary reflection prove to be valid or to be acceptable in trans-disciplinary terms depends upon certain preconditions, which have to be fulfilled for securing scientific quality and social trust in advisory contexts. The present book is written by experts and practitioners of interdisciplinary research and policy advice. It analyses topical and methodological approaches towards interdisciplinarity, starting with the current role of scientific research in society. The volume continues with contributions to the issues of knowledge and acting and to trans-disciplinary deliberation. The final conclusions address the scientific system as substantial actor itself as well as the...

    Rust, K.R.; Wilson, J.M.

    1992-06-01

    The Superconducting Super Collider's Medium Energy Booster Abort (MEBA) kicker modulator will supply a current pulse to the abort magnets which deflect the proton beam from the MEB ring into a designated beam stop. The abort kicker will be used extensively during testing of the Low Energy Booster (LEB) and the MEB rings. When the Collider is in full operation, the MEBA kicker modulator will abort the MEB beam in the event of a malfunction during the filling process. The modulator must generate a 14-μs wide pulse with a rise time of less than 1 μs, including the delay and jitter times. It must also be able to deliver a current pulse to the magnet proportional to the beam energy at any time during ramp-up of the accelerator. Tracking the beam energy, which increases from 12 GeV at injection to 200 GeV at extraction, requires the modulator to operate over a wide range of voltages (4 kV to 80 kV). A vacuum spark gap and a thyratron have been chosen for test and evaluation as candidate switches for the abort modulator. Modulator design, switching time delay, jitter and pre-fire data are presented

    2007-11-01

    A central recommendation from the Pew Health Commission to educators has been to empower future care providers to function effectively as teams. Administrators and faculty members within a school of allied health sciences thus established an interdisciplinary program where students would learn to function as team members and demonstrate competencies required for practice in diverse, demanding, and continually changing health care environments. Students from five disciplines have participated in featured events, mentored activities and capstone projects, earning credit in an interdisciplinary course of study that complements offerings in their home disciplines. This follow-up article reports on the progress and development since 2002 of an interdisciplinary program known as Team IDEAL. Formative evaluation measures used to assess satisfaction with the program are presented alongside a discussion of new directions. Team IDEAL will move forward in a streamlined form that reflects its central aim. IDEAL leadership will remain cognizant of the effects of discipline-specific curricular changes, complex programming, and student perspectives on the process interdisciplinary education.

    2017-06-01

    Pressure sores in geriatric patients represent a challenge for all disciplines involved in the treatment process; however, the prerequisite for successful treatment is the elaboration of an interdisciplinary treatment concept. The treatment goals should be adapted to the individual needs of the patients including the life situation, general condition and local findings. In addition to general basic operative techniques, such as wound cleansing and conditioning, plastic and reconstructive surgery provides a wide range of highly specialized operative techniques for the treatment of these patients by which a definitive defect coverage can be achieved. The aim of this article is to raise awareness for these complex and highly specialized procedures for all disciplines participating in the treatment in order to improve the interdisciplinary cooperation and ultimately the quality of treatment.

    Reforming graduate medical, nursing and health administrators' education to include the core competencies of interdisciplinary teamwork and quality improvement (QI) techniques is a key strategy to improve quality in hospital settings. Practicing clinicians are best positioned in these settings to understand systems issues and craft potential solutions. The authors describe how, in ten months during 2004 and 2005 the school of medicine, the school of nursing, and an administrative residency program, all at Johns Hopkins University, implemented and evaluated the Achieving Competency Today II Program (ACT II), a structured and interdisciplinary approach to learning QI that was piloted at various sites around the United States. Six teams of learners participated, each consisting of a medical, nursing, and administrative resident. The importance of interdisciplinary participation in planning QI projects, the value of the patient's perspective on systems issues, and the value of a system's perspective in crafting solutions to issues all proved to be valuable lessons. Challenges were encountered throughout the program, such as (1) participants' difficulties in balancing competing academic, personal and clinical responsibilities, (2) difficulties in achieving the intended goals of a broad curriculum, (3) barriers to openly discussing interdisciplinary team process and dynamics, and (4) the need to develop faculty expertise in systems thinking and QI. In spite of these challenges steps have been identified to further enhance and develop interdisciplinary education within this academic setting.

    A novel method is proposed for simulating free space field propagation from a source plane to a destination plane that is applicable for both small and large propagation distances. The angular spectrum method (ASM) was widely used for simulating near field propagation, but it caused a numerical error when the propagation distance was large because of aliasing due to under sampling. Band limited ASM satisfied the Nyquist condition on sampling by limiting a bandwidth of a propagation field to avoid an aliasing error so that it could extend the applicable propagation distance of the ASM. However, the band limited ASM also made an error due to the decrease of an effective sampling number in a Fourier space when the propagation distance was large. In the proposed wide range ASM, we use a non-uniform sampling in a Fourier space to keep a constant effective sampling number even though the propagation distance is large. As a result, the wide range ASM can produce simulation results with high accuracy for both far and near field propagation. For non-paraxial wave propagation, we applied the wide range ASM to a shifted destination plane as well. (paper)

    To qualitatively explore physiotherapy students' perceptions of online e-learning for chronic disease management using a previously developed, innovative and interactive, evidence-based, e-learning package: Rheumatoid Arthritis for Physiotherapists e-Learning (RAP-eL). Physiotherapy students participated in three focus groups in Perth, Western Australia. Purposive sampling was employed to ensure maximum heterogeneity across age, gender and educational background. To explore students' perspectives on the advantages and disadvantages of online e-learning, ways to enhance e-learning, and information/learning gaps in relation to interdisciplinary management of chronic health conditions, a semi-structured interview schedule was developed. Verbatim transcripts were analysed using inductive methods within a grounded theory approach to derive key themes. Twenty-three students (78 % female; 39 % with previous tertiary qualification) of mean (SD) age 23 (3.6) years participated. Students expressed a preference for a combination of both online e-learning and lecture-style learning formats for chronic disease management, citing flexibility to work at one's own pace and time, and access to comprehensive information as advantages of e-learning learning. Personal interaction and ability to clarify information immediately were considered advantages of lecture-style formats. Perceived knowledge gaps included practical application of interdisciplinary approaches to chronic disease management and developing and implementing physiotherapy management plans for people with chronic health conditions. Physiotherapy students preferred multi-modal and blended formats for learning about chronic disease management. This study highlights the need for further development of practically-oriented knowledge and skills related to interdisciplinary care for people with chronic conditions among physiotherapy students. While RAP-eL focuses on rheumatoid arthritis, the principles of learning apply to

    2015-11-01

    Students need to think and work across disciplinary boundaries in the twenty-first century. However, it is unclear what interdisciplinary thinking means and how to analyze interdisciplinary interactions in teamwork. In this paper, drawing on multiple theoretical perspectives and empirical analysis of discourse contents, we formulate a theoretical framework that helps analyze interdisciplinary reasoning and communication (IRC) processes in interdisciplinary collaboration. Specifically, we propose four interrelated IRC processes-integration, translation, transfer, and transformation, and develop a corresponding analytic framework. We apply the framework to analyze two meetings of a project that aims to develop interdisciplinary science assessment items. The results illustrate that the framework can help interpret the interdisciplinary meeting dynamics and patterns. Our coding process and results also suggest that these IRC processes can be further examined in terms of interconnected sub-processes. We also discuss the implications of using the framework in conceptualizing, practicing, and researching interdisciplinary learning and teaching in science education.

    Wiley, P. H.; Manus, E. A. (Inventor)

    1978-01-01

    A circuit deriving an output voltage that is proportional to the logarithm of a dc input voltage susceptible to wide variations in amplitude includes a constant current source which forward biases a diode so that the diode operates in the exponential portion of its voltage versus current characteristic, above its saturation current. The constant current source includes first and second, cascaded feedback, dc operational amplifiers connected in negative feedback circuit. An input terminal of the first amplifier is responsive to the input voltage. A circuit shunting the first amplifier output terminal includes a resistor in series with the diode. The voltage across the resistor is sensed at the input of the second dc operational feedback amplifier. The current flowing through the resistor is proportional to the input voltage over the wide range of variations in amplitude of the input voltage.

    2013-01-01

    This study investigates interdisciplinary interactions that take place during the research, development, and early conceptual design phases in the design of large-scale complex engineered systems (LaCES) such as aerospace vehicles. These interactions, that take place throughout a large engineering development organization, become the initial conditions of the systems engineering process that ultimately leads to the development of a viable system. This paper summarizes some of the challenges and opportunities regarding social and organizational issues that emerged from a qualitative study using ethnographic and survey data. The analysis reveals several socio-technical couplings between the engineered system and the organization that creates it. Survey respondents noted the importance of interdisciplinary interactions and their benefits to the engineered system as well as substantial challenges in interdisciplinary interactions. Noted benefits included enhanced knowledge and problem mitigation and noted obstacles centered on organizational and human dynamics. Findings suggest that addressing the social challenges may be a critical need in enabling interdisciplinary interactions

  2. Teaching Earth Sciences as an interdisciplinary subject: Novel module design involving research literature

    Science.gov (United States)

    Tong, Vincent C. H.

    2010-05-01

    The study of Earth Sciences requires an interdisciplinary approach as it involves understanding scientific knowledge originating from a wide spectrum of research areas. Not only does it include subjects ranging from, for instance, hydrogeology to deep crustal seismology and from climate science to oceanography, but it also has many direct applications in closely related disciplines such as environmental engineering and natural resources management. While research crossing traditional disciplinary boundaries in geosciences is becoming increasingly common, there is only limited integration of interdisciplinary research in the teaching of the subject. Given that the transition from undergraduate education based on subject modules to postgraduate interdisciplinary research is never easy, such integration is a highly desirable pedagogical approach at both undergraduate and postgraduate levels. My presentation is based on a recent teaching project involving novel design of an undergraduate course. The course is implemented in order to address the synergy between research and teaching (Tong, 2009). This project has been shown to be effective and successful in teaching geosciences undergraduates at the University of London. The module consists of studying core geophysical principles and linking them directly to a selection of recently published research papers in a wide range of interdisciplinary applications. Research reviewing and reporting techniques are systematically developed, practised and fully integrated into teaching of the core scientific theories. A fully-aligned assignment with a feedback website invites the students to reflect on the scientific knowledge and the study skills related to research literature they have acquired in the course. This teaching project has been recognized by a teaching award (http://www.clpd.bbk.ac.uk/staff/BETA). In this presentation, I will discuss how undergraduate teaching with a focus on research literature in Earth Sciences can

    A significant problem of integrating renewable energies into the electricity system is the temporally fluctuating energy production by wind and solar power plants. Thus, in order to meet the ambitious long-term targets on CO2 emission reduction, long-term viable low-carbon options for balancing electricity will be needed. This interdisciplinary study analyses published future energy scenarios in order to get an impression of the required balancing capacities and shows which framework conditions should be modified to support their realisation. The authors combine their perspectives from energy engineering, technology assessment, political science, economical science and jurisprudence and address science, politics, actors in the energy sector and the interested public. Respectively, requirements for the balancing systems are analysed, considering the case of Germany as a large country with high ambitions to reduce greenhouse gas emissions. Additionally, an approach to investigate the optimal design of the techn...

    Unique food products constitute a very important element of European food business, culture, identity and heritage. Understanding the uniqueness of food in Europe from a research-based interdisciplinary perspective will be a critical factor in promoting the competitiveness of artisanal food industries going forward both locally and internationally. Success will support the competitiveness of the European food industry, in particular, small and medium enterprises, by enabling substantial product differentiation potential for producers and providing ample variety in food choice for the consumer. In addition, it will contribute to promotion of sustainable agriculture and development of rural areas, protecting them from depopulation. In order to meet the demands of a developing fundamental shift in European Union agricultural focus to greener, sustainable farming practices and wider rural development and to ensure success for local small-scale producers, this paper discusses the future direction of research in the field of unique European foods. The paper presents a perspective which promotes optimisation and innovation in unique food products in Europe through the integration of advanced knowledge and technologies. A framework is presented covering location, identity, perception and well-being as research areas needing synergy to bridge the research knowledge deficit in determination and specification of food identity in the European Union. The ultimate aim being promotion of sustainable agriculture and rural development, particularly in territories across the European Union where unique food is strategically and scientifically under-defined. © 2013 Society of Chemical Industry.

  7. High voltage wide range marx generator design and construction

    International Nuclear Information System (INIS)

    Thompson, J.E.

    1976-01-01

    A wide range, long pulse, Marx generator has been designed and constructed for the purpose of exciting a thermionic electron gun utilized for quasi-cw gas laser medium ionization. The Marx generator has been specifically designed to operate over a voltage range variable from 100 kV to 200 kV into a resistive load of between 83 kΩ and open circuit. This wide operating range, both in voltage and load impedance, was obtained using interstage coupling capacitors to assure overvoltage and subsequent breakdown of the three element spark gap switches used. This paper will discuss the motivation and specific application for the Marx generator and will present the relevant design procedure with particular emphasis on the interstage coupling and triggering techniques employed. Experimental data regarding the measured Marx generator performance will also be presented

  8. Theology and psychology – the interdisciplinary work of Fraser Watts

    Directory of Open Access Journals (Sweden)

    Willem J. Smith

    2005-10-01

    Full Text Available In the preface to his book, Theology and Psychology, Fraser Watts, a lecturer in Theology and Natural Science at the University of Cambridge, states that he approaches “… the interface between theology and psychology by looking at each discipline from the perspective of the other. This includes a religious perspective on several current hot topics in psychology, such as evolution, neuroscience, and computer intelligence. I also consider theological topics like divine action, salvation history and eschatology, in each case using the psychological perspective in a different way”. By taking an interdisciplinary approach, Watts aims at proposing a psychology of religious experience. He considers theology to be the rational reflection on the Christian tradition. When exponents of this tradition are in dialogue with exponents of psychology, the focus falls on human nature. Watts admits that a certain lack of competence in one of the two disciplines can be a problem when working in an interdisciplinary way. However, he is willing to take the risk. Watts worked in psychology for 25 years and was also involved with a medical research council, before taking up a position at the Faculty of Divinity, University of Cambridge.

  11. Soil Compressibility Models for a Wide Stress Range

    KAUST Repository

    Chong, Song-Hun

    2016-03-03

    Soil compressibility models with physically correct asymptotic void ratios are required to analyze situations that involve a wide stress range. Previously suggested models and other functions are adapted to satisfy asymptotic void ratios at low and high stress levels; all updated models involve four parameters. Compiled consolidation data for remolded and natural clays are used to test the models and to develop correlations between model parameters and index properties. Models can adequately fit soil compression data for a wide range of stresses and soil types; in particular, models that involve the power of the stress σ\\'β display higher flexibility to capture the brittle response of some natural soils. The use of a single continuous function avoids numerical discontinuities or the need for ad hoc procedures to determine the yield stress. The tangent stiffness-readily computed for all models-should not be mistaken for the small-strain constant-fabric stiffness. © 2016 American Society of Civil Engineers.

    2015-01-01

    ENTRIA (''Disposal Options for Radioactive Residues: Interdisciplinary Analyses and Development of Evaluation Principles'', www.entria.de) is a joint research project carried out by twelve departments and institutes from German universities and major research institutions and one partner from Switzerland. It is financed by the German Ministry of Education and Research (BMBF). Scientists representing natural sciences, civil engineering, philosophy, law, social and political sciences, and technology assessment carry out disciplinary and interdisciplinary research addressing three options to manage especially high-level radioactive waste: - Final disposal in deep geological formations without any arrangements for retrieval, - disposal in deep geological formations with arrangements for monitoring and retrieval, and - (prolonged) surface (or near-surface) storage. In the paper, the following selected research topics - both disciplinary and interdisciplinary - are briefly introduced in order to provide an impression of the project scope: - Surface storage, - reference concepts for emplacement in deep geological formations with retrievability and monitoring, - radiation exposure and justification of measures, - interdisciplinary perspectives on dose limits, - comparative studies on nuclear waste governance, - nuclear waste governance in Switzerland, - public involvement and the German Site Selection Act, and - citizens' jury.

    The implementation of interdisciplinary teams in the intensive care unit (ICU) has focused attention on leadership behavior. A daily recurrent situation in ICUs in which both leadership behavior and interdisciplinary teamwork are integrated concerns the interdisciplinary rounds (IDRs). Although IDRs are recommended to provide optimal interdisciplinary and patient-centered care, there are no checklists available for leading physicians. We tested the measurement properties and implementation of a checklist to assess the quality of leadership skills in interdisciplinary rounds. The measurement properties of the checklist, which included 10 essential quality indicators, were tested for interrater reliability and internal consistency and by factor analysis. The interrater reliability among 3 raters was good (κ, 0.85) and the internal consistency was acceptable (α, 0.74). Factor analysis showed all factor loadings on 1 domain (>0.65). The checklist was further implemented during videotaped IDRs which were led by senior physicians and in which 99 patients were discussed. Implementation of the checklist showed a wide range of "no" and "yes" scores among the senior physicians. These results may underline the need for such a checklist to ensure tasks are synchronized within the team.

  20. Research design: the methodology for interdisciplinary research framework.

    Tobi, Hilde; Kampen, Jarl K

    2018-01-01

    Many of today's global scientific challenges require the joint involvement of researchers from different disciplinary backgrounds (social sciences, environmental sciences, climatology, medicine, etc.). Such interdisciplinary research teams face many challenges resulting from differences in training and scientific culture. Interdisciplinary education programs are required to train truly interdisciplinary scientists with respect to the critical factor skills and competences. For that purpose this paper presents the Methodology for Interdisciplinary Research (MIR) framework. The MIR framework was developed to help cross disciplinary borders, especially those between the natural sciences and the social sciences. The framework has been specifically constructed to facilitate the design of interdisciplinary scientific research, and can be applied in an educational program, as a reference for monitoring the phases of interdisciplinary research, and as a tool to design such research in a process approach. It is suitable for research projects of different sizes and levels of complexity, and it allows for a range of methods' combinations (case study, mixed methods, etc.). The different phases of designing interdisciplinary research in the MIR framework are described and illustrated by real-life applications in teaching and research. We further discuss the framework's utility in research design in landscape architecture, mixed methods research, and provide an outlook to the framework's potential in inclusive interdisciplinary research, and last but not least, research integrity.

    In a Nuclear Power Plant, the developed power is proportional to the emitted neutron flux. The 10 to 11 decades measurement range from source to power generally needs 3 distinct neutron measurement chains to be monitored. A wide range neutron monitoring system may cover this range with only one sensor followed by adequate electronics. In the past this concept has been developed with an analogue technology which was presenting some drawbacks (slow log amplifier, components perenniality). In this paper, we introduce a completely new design, that makes use of a recent technology, including full linear input electronics, and advanced digital signal processing. As far as the sensor is concerned, both a well known commercial fission chamber, or an innovative wide range sensor presenting a high sensitivity may be used. The basic concept is that the single signal is continuously processed by three different electronic stages, each one being dedicated to approximately one third of the full range: pulse, Campbelling and current modes. After amplification, appropriate shaping, this signal is numerically filtered by a Kalman filter algorithm to compute the neutron flux as well as the reactor period. A specifically developed test module allows the surveillance of the sensor and the electronics via stimuli injections and characteristic curves plotting. A computerised simulation of the whole chain is used to validate the signal processing algorithms evolutions. In the paper we will specifically develop the metrological performances of this chain and the general agreement that exists between simulated and measured values. (authors)

    As neuroscience knowledge grows in its scope of societal applications so does the need to educate a wider audience on how to critically evaluate its research findings. Efforts at finding teaching approaches that are interdisciplinary, accessible and highly applicable to student experience are thus ongoing. The article describes an interdisciplinary undergraduate health course that combines the academic study of contemplative neuroscience with contemplative practice, specifically yoga. The class aims to reach a diverse mix of students by teaching applicable, health-relevant neuroscience material while directly connecting it to first-hand experience. Outcomes indicate success on these goals: The course attracted a wide range of students, including nearly 50% non-science majors. On a pre/post test, students showed large increases in their knowledge of neuroscience. Students’ ratings of the course overall, of increases in positive feelings about its field, and of their progress on specific course objectives were highly positive. Finally, students in their written work applied neuroscience course content to their personal and professional lives. Such results indicate that this approach could serve as a model for the interdisciplinary, accessible and applied integration of relevant neuroscience material into the undergraduate health curriculum.

    The Dzyaloshinskii-Moriya interaction (DMI) in magnetic objects is of enormous interest, because it generates built-in chirality of magnetic domain walls (DWs) and topologically protected skyrmions, leading to efficient motion driven by spin-orbit torques. Because of its importance for both potential applications and fundamental research, many experimental efforts have been devoted to DMI investigation. However, current experimental probing techniques cover only limited ranges of the DMI strength and have specific sample requirements. Thus, there are no versatile methods to quantify DMI over a wide range of values. Here, we present such an experimental scheme, which is based on the angular dependence of asymmetric DW motion. This method can be used to determine values of DMI much larger than the maximum strength of the external magnetic field strength, which demonstrates that various DMI strengths can be quantified with a single measurement setup. This scheme may thus prove essential to DMI-related emerging fields in nanotechnology.

    Piso, Zachary; O'Rourke, Michael; Weathers, Kathleen C

    2016-04-01

    Social studies of interdisciplinary science investigate how scientific collaborations approach complex challenges that require multiple disciplinary perspectives. In order for collaborators to meet these complex challenges, interdisciplinary collaborations must develop and maintain integrative capacity, understood as the ability to anticipate and weigh tradeoffs in the employment of different disciplinary approaches. Here we provide an account of how one group of interdisciplinary fog scientists intentionally catalyzed integrative capacity. Through conversation, collaborators negotiated their commitments regarding the ontology of fog systems and the methodologies appropriate to studying fog systems, thereby enhancing capabilities which we take to constitute integrative capacity. On the ontological front, collaborators negotiated their commitments by setting boundaries to and within the system, layering different subsystems, focusing on key intersections of these subsystems, and agreeing on goals that would direct further investigation. On the methodological front, collaborators sequenced various methods, anchored methods at different scales, validated one method with another, standardized the outputs of related methods, and coordinated methods to fit a common model. By observing the process and form of collaborator conversations, this case study demonstrates that social studies of science can bring into critical focus how interdisciplinary collaborators work toward an integrated conceptualization of study systems.

    As a part of the emittance measurements planned for the FEL injector at the Thomas Jefferson National Accelerator Facility (Jefferson Lab), the authors have developed an emittance measurement system that covers the wide dynamic range of bunch charges necessary to fully characterize the high-DC-voltage photocathode gun. The measurements are carried out with a variant of the classical two-slit method using a slit to sample the beam in conjunction with a wire scanner to measure the transmitted beam profile. The use of commercial, ultra-low noise picoammeters makes it possible to cover the wide range of desired bunch charges, with the actual measurements made over the range of 0.25 pC to 125 pC. The entire system, including its integration into the EPICS control system, is discussed

    High energy physics experiments running at high interaction rates frequently require long record lengths for determining a level 1 trigger. The easiest way to provide a long event record is by digital means. In applications requiring wide dynamic range, however, digitization of an analog signal to obtain the digital record has been impossible due to lack of high speed, wide range FADCs. One such application is the readout of thousands of photomultiplier tubes in fixed target and colliding beam experiment calorimeters. A circuit has been designed for digitizing PMT signals over a wide dynamic range (17--18 bits) with 8 bits of resolution at rates up to 53 MHz. Output from the circuit is in a floating point format with a 4 bit exponent and an 8 bit mantissa. The heart of the circuit is a full custom integrated circuit called the QIE (Charge Integrator and Encoder). The design of the QIE and associated circuitry reported here permits operation over a 17 bit dynamic range. Tests of the circuit with a PMT input and a pulsed laser have provided respectable results with little off line correction. Performance of the circuit for demanding applications can be significantly enhanced with additional off line correction. Circuit design, packaging issues, and test results of a multirange device are presented for the first time.

    Full Text Available the domain of Art critique and becoming a philosophical argument. How can we think of Perspective as symbolic Form? Is Perspective really a symbolic form? Why is Perspective so important? Because at the beginning of the Modern Age, Perspective as spiritual figure grounds many symbolic or even many scientific constructions. We could we say that perspective open the foundation of modern science as such. The “Geometrization” of Vision, beginning with perspective, will be for us the interpretative key in order to understand the Modern Age as a whole.  This understanding will allow us to understand the anthropologic dimension arising from the Modern Age, called „Perspectivism“. Assuming that perspective was neither only an invention of painting nor of geometry nor of philosophy, taken as singular fields of human inquiry, we will try to sketch the genesis of “perspective” from an interdisciplinary point of view. By doing so, we will also try to fix its deep significance for the anthropology of the Modern Age. Living and feeling in a perspectival world is the real invention of the Modern Age, one that overcame the closed Cosmos of the Middle Ages in order to reveal to mankind its own potential. Our interdisciplinary approach will proceed from many points of view (history of art, science, theology, anthropology and converge on the idea of a new kind of human experience. Such an interdisciplinary approach will open new questions about our present time. Are we justified in thinking of our experience today as perspectival? What does it mean today to think from perspectives in the manifold dimensions of our living and to face to the complexity of our times?

    Natural and supernatural explanations are used to interpret the same events in a number of predictable and universal ways. Yet little is known about how variation in diverse cultural ecologies influences how people integrate natural and supernatural explanations. Here, we examine explanatory coexistence in three existentially arousing domains of human thought: illness, death, and human origins using qualitative data from interviews conducted in Tanna, Vanuatu. Vanuatu, a Melanesian archipelago, provides a cultural context ideal for examining variation in explanatory coexistence due to the lack of industrialization and the relatively recent introduction of Christianity and Western education. We argue for the integration of interdisciplinary methodologies from cognitive science and anthropology to inform research on explanatory coexistence.

    The paper describes a portable battery-operated radiation survey meter for monitoring a wide range of X- and gamma-ray exposure rates from 1 mR/h to 100 R/h. The instrument Incorporates a halogen GM tube as the detector and a count-rate meter for indication. A transistorized d.c. -d.c. converter supplies the necessary high voltage to the GM counter. The instrument response has been made energy independent in the energy range 80 keV to 1.25 MeV. Further, the response is linear over the entire range of exposure rates. Suitable extension rods have been designed to provide sufficient separation between the probe and the meter in cases where remote monitoring is necessary because of high fields. (author)

  20. Negotiating geophysical hazards in Nepal: An interdisciplinary approach

    Oven, Katie; Petley, Dave; Rosser, Nick; Dunn, Chris; Rigg, Jonathan

    2010-05-01

    It is widely accepted that the impact of natural hazards reflects not only the nature of geophysical processes but also the social conditions that prevail. The need for collaborative research to address these complex interactions between the natural and human systems is well recognised, however moving from theory to practice presents a number of significant challenges. How researchers frame problems; develop their research questions; select the methodologies to explore these questions; and privilege certain knowledges over others, can be seen to vary between physical and social science. Drawing on a case study examining the vulnerability of rural communities to landslides in the Upper Bhote Koshi Valley, Central Nepal, this paper explores how these barriers can be overcome and the benefits of undertaking interdisciplinary research within the natural hazards field. This research investigates the different framings of landslide risk and vulnerability from different stakeholder and disciplinary perspectives. Specifically, we ask: 1. Who is vulnerable to landslide hazard? 2. Why do people occupy landslide prone areas? 3. How do ‘at risk' rural communities perceive and respond to landslide hazard and risk? The findings, based on a series of participatory methodologies, challenge a number of assumptions made regarding landslide vulnerability in mountain communities. Within the Upper Bhote Koshi Valley clear transitions in settlement patterns, rural livelihoods and thus the occupation of landslide prone areas have been seen over time. For the majority of households, their decision to occupy these areas is driven by the economic and social benefits associated with the Arniko Highway which runs through the valley, linking Nepal with Tibet. Landslide vulnerability therefore emerges not just from societal marginalisation but also from situations of relative prosperity. The findings suggest that occupants of landslide prone areas have a good understanding of landslide hazard

    2014-01-01

    An optofluidically tunable fiber laser based on multimode interference (MMI) effects with a wide tuning range is proposed and demonstrated. The tunable mechanism is based on an MMI fiber filter fabricated using a special fiber known as no-core fiber, which is a multimode fiber (MMF) without cladding. Therefore, when the MMI filter is covered by liquid the optical properties of the no-core fiber are modified, which allow us to tune the peak wavelength response of the MMI filter. Rather than applying the liquid on the entire no-core fiber, we change the liquid level along the no-core fiber, which provides a highly linear tuning response. In addition, by selecting the adequate refractive index of the liquid we can also choose the tuning range. We demonstrate the versatility of the optofluidically tunable MMI filter by wavelength tuning two different gain media, erbium doped fiber and a semiconductor optical amplifier, achieving tuning ranges of 55 and 90 nm respectively. In both cases, we achieve side-mode suppression ratios (SMSR) better than 50 dBm with output power variations of less than 0.76 dBm over the whole tuning range. (paper)

    According to the requirements of the tritium related systems of the TBM (Test Blanket Module) for monitoring the on-line tritium concentration, a wide-range tritium-concentration detector has been developed to measure the tritium concentration in the range of 10 4 Bq/ml - 5*10 8 Bq/ml. This detector is combined with a low-memory helium ionization chamber. The weak current signal collected in the ionization chamber is converted to the voltage signal by an I-V converter. The minimum weak current which the detector could be measured is 10 -14 A. The performance of the background current and the current response linearity of the prototype have been tested. The test result indicates that the linear response of the current signal of the prototype without connecting the ionization chamber is good. The linear correlation coefficient is R 2 = 0.998

    2013-04-01

    Full Text Available Centrifugal compressors are widely used in industrial applications thanks to their high efficiency. They are able to provide a wide operating range before reaching the flow barrier or surge limits. Performances and range are described by compressor maps obtained experimentally. After a description of performance test rig, this article compares measured centrifugal compressor performances with computational fluid dynamics results. These computations are performed at steady conditions with R134a refrigerant as fluid. Navier-Stokes equations, coupled with k-ε turbulence model, are solved by the commercial software ANSYS-CFX by means of volume finite method. Input conditions are varied in order to calculate several speed lines. Theoretical isentropic efficiency and theoretical surge line are finally compared to experimental data.

    The number of publications on consumer food decision making and its predictors and correlates has been steadily increasing over the last three decades. Given that different scientific disciplines illuminate this topic from different perspectives, it is necessary to develop an interdisciplinary overview. The aim of this study is to conduct a systematic interdisciplinary mapping (SIM) review by using rapid review techniques to explore the state-of-the-art, and to identify hot topics and research gaps in this field. This interdisciplinary review includes 1,820 publications in 485 different journals and other types of publications from more than ten disciplines (including nutritional science, medicine/health science, psychology, food science and technology, business research, etc.) across a period of 60 years. The identified predictors of food decision making were categorized in line with the recently proposed DONE (Determinants Of Nutrition and Eating behavior) framework. After applying qualitative and quantitative analyses, this study reveals that most of the research emphasizes biological, psychological, and product-related predictors, whereas policy-related influences on food choice are scarcely considered.

  12. Can clinicians and scientists explain and prevent unexplained underperformance syndrome in elite athletes: an interdisciplinary perspective and 2016 update

    2015-01-01

    The coach and interdisciplinary sports science and medicine team strive to continually progress the athlete's performance year on year. In structuring training programmes, coaches and scientists plan distinct periods of progressive overload coupled with recovery for anticipated performances to be delivered on fixed dates of competition in the calendar year. Peaking at major championships is a challenge, and training capacity highly individualised, with fine margins between the training dose necessary for adaptation and that which elicits maladaptation at the elite level. As such, optimising adaptation is key to effective preparation. Notably, however, many factors (eg, health, nutrition, sleep, training experience, psychosocial factors) play an essential part in moderating the processes of adaptation to exercise and environmental stressors, for example, heat, altitude; processes which can often fail or be limited. In the UK, the term unexplained underperformance syndrome (UUPS) has been adopted, in contrast to the more commonly referenced term overtraining syndrome, to describe a significant episode of underperformance with persistent fatigue, that is, maladaptation. This construct, UUPS, reflects the complexity of the syndrome, the multifactorial aetiology, and that ‘overtraining’ or an imbalance between training load and recovery may not be the primary cause for underperformance. UUPS draws on the distinction that a decline in performance represents the universal feature. In our review, we provide a practitioner-focused perspective, proposing that causative factors can be identified and UUPS explained, through an interdisciplinary approach (ie, medicine, nutrition, physiology, psychology) to sports science and medicine delivery, monitoring, and data interpretation and analysis.

    2017-11-01

    This study proposes the wide-ranged multistage morphing waverider design method. The flow field structure and aerodynamic characteristics of multistage waveriders are also analyzed. In this method, the multistage waverider is generated in the same conical flowfield, which contains a free-stream surface and different compression-stream surfaces. The obtained results show that the introduction of the multistage waverider design method can solve the problem of aerodynamic performance deterioration in the off-design state and allow the vehicle to always maintain the optimal flight state. The multistage waverider design method, combined with transfiguration flight strategy, can lead to greater design flexibility and the optimization of hypersonic wide-ranged waverider vehicles.

    1998-01-01

    Background: The documentation of acute and chronic treatment sequelae is a decisive precondition for the appropriate evaluation of the treatment quality of any cancer therapy. Methods and results: Interdisciplinary (inter)national efforts have resulted in a new consensus for recording of treatment sequelae in oncology. While the acute treatment side effects (day 1 to 90 after treatment) are recommended to be documented and evaluated using the Common Toxicity Criteria (CTC), for the chronic treatment side effects (day 91 and thereafter) the Late Effect Normal Tissue (LENT) criteria are to be implemented. The latter classification system allows to differentiate between the Subjective, Objective, Management and Analytic (SOMA) toxicity aspects. Both classification systems can be implemented not only for clinical applications using radiotherapy or chemotherapy alone but also for combinations with each other or with other treatment modalities. This allows for an effective interdisciplinary comparison between different treatment concepts not only within each institution but also in multicenter trials. Conclusions: Prospective documentation and evaluation of treatment toxicity in oncology should be intensified and systematically included in future mono- and multi-institutional clinical trials.

    The need to train early-career interdisciplinary, solutions-driven sustainability researchers has never been more apparent than today. To meet this challenge, educators at the Universities of Maine, New Hampshire, and Rhode Island have collaborated with their students to design and assess an interdisciplinary, multi-university course meant to develop the skills, content knowledge, and voice that are seen as critical for training the next generation of interdisciplinary sustainability researchers. We developed a rubric and conducted a mixed methods analysis of sustainability science learning outcomes identified as central to successful sustainability research. We used these targeted outcomes as a guide to design and implement several activities that build these skills and competencies and advance the identified outcomes. These course learning outcomes focus on three major sustainability science competencies: (1) systems thinking, which focuses on improving students' abilities to build a deep understanding of dynamic social-ecological systems; (2) problem definition, which focuses on the skills necessary to identify and communicate sustainability problems by combining systems knowledge with multiple stakeholder perspectives; and (3) decision making, which focuses on the abilities required to create and communicate adaptable decisions to mitigate sustainability problems. Students were frequently asked to help co-create class meetings based on their own educational experiences and objectives.Based on a quantitative assessment of survey results taken before and after the course, several students tended to initially overestimate their capacity for undertaking interdisciplinary sustainability research, possibly because of a previously narrow exposure to these concepts from the perspective of a single discipline. Qualitative results indicate that students gained substantial experience and confidence in communication, and especially in collaboration, stakeholder engagement

  5. Doped silicene: Evidence of a wide stability range

    2011-06-17

    The effects of doping on the lattice structure, electronic structure, phonon spectrum, and electron-phonon coupling of low-buckling silicene are studied by first-principles calculations. Although the lattice is found to be very sensitive to the carrier concentration, it is stable in a wide doping range. The frequencies of the E2g-Γ and A′-K Raman modes can be used to probe the carrier concentration. In addition, the phonon dispersion displays Kohn anomalies at the Γ and K points which are reduced by doping. This implies that the electron-phonon coupling cannot be neglected in field-effect transistor applications. Copyright © 2011 EPLA.

    International Nuclear Information System (INIS)

    Tacconi, E.; Christiansen, C.

    1993-05-01

    Automatic gain control (AGC) techniques have been largely used since the beginning of electronics, but in most of the applications the dynamic response is slow compared with the carrier frequency. The problem of developing an automatic gain control with high dynamic response and wide control range simultaneously is analyzed in this work. An ideal gain control law, with the property that the total loop gain remains constant independent of the carrier amplitude, is obtained. The resulting AGC behavior is compared by computer simulations with a linear multiplier AGC. The ideal gain control law can be approximated using a transconductance amplifier. A practical circuit that has been used at CERN in the radio frequency loops of the Booster Synchrotron is presented. The circuit has high speed and 80-dB gain control range

    2017-04-01

    Drought events cause severe water and food insecurities in many developing countries where resilience to natural hazards and change is low due to a number of reasons (including poverty, social and political inequality, and limited access to information). Furthermore, with climate change and increasing pressures from population and societal change, populations are expected to experience future droughts outside of their historic range. Integrated water resources management is an established tool combining natural science, engineering and management to help address drought and associated impacts. However, it often lacks a strong social and cultural aspect, leading to poor implementation on the ground. For a more holistic approach to building resilience to future drought, a stronger interdisciplinary approach is required which can incorporate the local cultural context and perspectives into drought and water management, and communicate information effectively to communities. In this pilot project 'CreativeDrought', we use a novel interdisciplinary approach aimed at building resilience to future drought in rural Africa by combining hydrological modelling with rich local information and engaging communicative approaches from social sciences. The work is conducted through a series of steps in which we i) engage with local rural communities to collect narratives on drought experiences; ii) generate hydrological modelling scenarios based on IPCC projections, existing data and the collected narratives; iii) feed these back to the local community to gather their responses to these scenarios; iv) iteratively adapt them to obtain hypothetical future drought scenarios; v) engage the community with the scenarios to formulate new future drought narratives; and vi) use this new data to enhance local water resource management. Here we present some of the indigenous knowledge gathered through narratives and the hydrological modelling scenarios for a rural community in Southern Africa

    2015-03-01

    Full Text Available This paper focuses on how experienced science teachers talk about interdisciplinary collaboration and ethical perspectives in their educational practice, two important components in science education and central in research on socio-scientific issues and education for sustainable development. The teachers in this interview study were asked in detail about how they integrate such components in their teaching practice. The findings indicate that the teachers in the study value interdisciplinary collaboration and try to integrate ethical aspects in their teaching. However, the science teachers in this study encounter problems in the practical implementation as it demands excellent communication in the team. Furthermore, the science teachers rate their ethical competence as rather low. They also show signs of a decrease in their professional capital, as in decisions they can make related to their teaching practice. The process of interacting with and learning from others, here called social learning, is vital for interdisciplinary collaboration and integration of ethical aspects. Such issues place severe demands, not only on the science teacher, but also on the whole educational system.

    A significant problem of integrating renewable energies into the electricity system is the temporally fluctuating energy production by wind and solar power plants. Thus, in order to meet the ambitious long-term targets on CO{sub 2} emission reduction, long-term viable low-carbon options for balancing electricity will be needed. This interdisciplinary study analyses published future energy scenarios in order to get an impression of the required balancing capacities and shows which framework conditions should be modified to support their realisation. The authors combine their perspectives from energy engineering, technology assessment, political science, economical science and jurisprudence and address science, politics, actors in the energy sector and the interested public. Respectively, requirements for the balancing systems are analysed, considering the case of Germany as a large country with high ambitions to reduce greenhouse gas emissions. Additionally, an approach to investigate the optimal design of the technical system for balancing electricity over Europe is sketched. Looking at the challenges of a future energy system a mix of complementary technologies will prospectively become prevalent. In order to foster the needed innovation processes adequately, several funding mechanisms and legal regulations should be adapted. The authors give recommendations to handle major challenges in the development of the technical infrastructure, for the design of market conditions and for specific support of the application of balancing technologies.

    Petrochemical raw materials are an essential raw material for the production of detergents with a substantial portion of synthetic fatty alcohols being produced via hydroformylation of oil or coal derived olefins. Carbonylation processes other than hydroformylation have to date not been commercially employed for the production of fatty esters or alcohols. In this document we highlight the opportunities of converting olefins to esters using cobalt catalyzed alkoxycarbonylation. This process is highly versatile and applicable to a wide range of olefins, linear or branched, alpha or internal in combination with virtually any chain length primary or secondary alcohol allowing the synthesis of a diverse array of compounds such as ester ethoxylated surfactants, methyl branched detergents, lubricants and alkyl propanoates. Furthermore, alkoxycarbonylation of a broad olefin/paraffin hydrocarbon range could be used to produce the corresponding broad cut detergent alcohols. (orig.)

    1995-08-01

    Historically, ecological risk assessment at CERCLA sites [such as the Oak Ridge Reservation (ORR)], has focused on species that may be definitively associated with a contaminated area or source operable unit. Consequently the species that are generally considered are those with home ranges small enough such that multiple individuals or a distinct population can be expected to reside within the boundaries of the contaminated site. This approach is adequate for sites with single, discrete areas of contamination that only provide habitat for species with limited requirements. This approach is not adequate however for large sites with multiple, spatially separated contaminated areas that provide habitat for wide-ranging wildlife species. Because wide-ranging wildlife species may travel between and use multiple contaminated sites they may be exposed to and be at risk from contaminants from multiple locations. Use of a particular contaminated site by wide-ranging species will be dependent upon the amount of suitable habitat available at that site. Therefore to adequately evaluate risks to wide-ranging species at the ORR-wide scale, the use of multiple contaminated sites must be weighted by the amount of suitable habitat on OUs. This reservation-wide ecological risk assessment is intended to identify which endpoints are significantly at risk; which contaminants are responsible for this risk; and which OUs significantly contribute to risk.

    Computerized interdisciplinary plans of care have revitalized nurse-centric care plans into dynamic and meaningful electronic documents. To maximize the benefits of these documents, it is important to understand healthcare professionals' attitudes, specifically their confidence, for making computerized interdisciplinary care plans useful and meaningful documents. The purpose of the study was to test the psychometric properties of the Self-Efficacy for Interdisciplinary Plans of Care instrument intended to measure healthcare professionals' self-efficacy for using such documents. Content validity was assessed by an expert review panel. Content validity indices ranged from 0.75 to 1.00, with a scale CVI of 0.94. A sample of 389 healthcare providers completed the 14-item instrument. Principal axis factoring was used to assess factor structure. The exploratory factor analysis yielded a single-factor structure accounting for 71.76% of covariance. Cronbach internal consistency coefficient for the single factor solution was .97. The corrected item-total correlations ranged from 0.71 to 0.90. The coefficient of stability, during a 2-week period, with a subset of the sample (n = 38), was estimated at 0.82. The results of this study suggest that the Self-Efficacy for Interdisciplinary Plans of Care has sturdy reliability and validity for measuring the self-efficacy of healthcare providers to make computerized interdisciplinary plans of care meaningful and useful documents.

  16. Position Paper: Designing Complex Systems to Support Interdisciplinary Cognitive Work

    2016-01-01

    The paper argues that the field we can call cognitive science of interdisciplinary collaboration is an important area of study for improving design of Large-Scale Complex Systems (LaCES) and supporting cognitive work. The paper mostly raised questions that have been documented in earlier qualitative analysis studies, and provided possible avenues of exploration for addressing them. There are likely further contributions from additional disciplines beyond those mentioned in this paper that should be considered and integrated into such a cognitive science framework. Knowledge and awareness of various perspectives will help to inform the types of interventions available for improving LaCES design and functionality. For example, a cognitive interpretation of interdisciplinary collaborations in LaCES elucidated the need for a "translator" or "mediator" in helping subject matter experts to transcend language boundaries, mitigate single discipline bias, support integrative activities, and correct misaligned objectives. Additional research in this direction is likely to uncover similar gaps and opportunities for improvements in practice.

    This paper presents an optimized control which makes LLC resonant converters operate with a wider load range and provides good closed-loop performance. The proposed control employs two paralleled digital compensations to guarantee the good closed-loop performance in a wide load range during the steady state, an optimized trajectory control will take over to change the gate-driving signals immediately at the load transients. Finally, the proposed control has been implemented and tested on a 150W 200kHz 400V/24V LLC resonant converter and the result validates the proposed method.

  19. Rawls's Wide Reflective Equilibrium as a Method for Engaged Interdisciplinary Collaboration: Potentials and Limitations for the Context of Technological Risks.

    2018-05-01

    The introduction of new technologies in society is sometimes met with public resistance. Supported by public policy calls for "upstream engagement" and "responsible innovation," recent years have seen a notable rise in attempts to attune research and innovation processes to societal needs, so that stakeholders' concerns are taken into account in the design phase of technology. Both within the social sciences and in the ethics of technology, we see many interdisciplinary collaborations being initiated that aim to address tensions between various normative expectations about science and engineering and the actual outcomes. However, despite pleas to integrate social science research into the ethics of technology, effective normative models for assessing technologies are still scarce. Rawls's wide reflective equilibrium (WRE) is often mentioned as a promising approach to integrate insights from the social sciences in the normative analysis of concrete cases, but an in-depth discussion of how this would work in practice is still lacking. In this article, we explore to what extent the WRE method can be used in the context of technology development. Using cases in engineering and technology development, we discuss three issues that are currently neglected in the applied ethics literature on WRE. The first issue concerns the operationalization of abstract background theories to moral principles. The second issue concerns the inclusiveness of the method and the demand for openness. The third issue is how to establish whether or not an equilibrium has been reached. These issues should be taken into account when applying the methods to real-world cases involving technological risks. Applying the WRE method in the context of engaged interdisciplinary collaboration requires sensitivity for issues of power and representativeness to properly deal with the dynamics between the technical and normative researchers involved as well as society at large.

    A new procedure to extract simultaneously continuous stopping power curves for several ions and several absorbers over a wide energy range and with statistical errors reduced to negligible level is presented. The method combines our novel time-of-flight based method with the capability of our K130 cyclotron and ECR ion-source to produce the so-called ion cocktails. The potential of the method is demonstrated with a 6.0 MeV/u cocktail consisting of {sup 16}O{sup 4+}, {sup 28}Si{sup 7+} and {sup 40}Ar{sup 10+} ions. The stopping power in polycarbonate in the energy range of 0.35-5 MeV/u has been determined with absolute uncertainty of less than 2.3% and with relative below 0.2%. The results are compared with literature data and with SRIM2000 parameterisation including cores and bonds corrections.

    A front-end application specified integrated circuit (ASIC) is developed with a wide dynamic range amplifier (WDAMP) to read-out signals from a photo-sensor like a photodiode. The WDAMP ASIC consists of a charge sensitive preamplifier, four wave-shaping circuits with different amplification factors and Wilkinson-type analog-to-digital converter (ADC). To realize a wider range, the integrating capacitor in the preamplifier can be changed from 4 pF to 16 pF by a two-bit switch. The output of a preamplifier is shared by the four wave-shaping circuits with four gains of 1, 4, 16 and 64 to adapt the input range of ADC. A 0.25-μm CMOS process (of UMC electronics CO., LTD) is used to fabricate the ASIC with four-channels. The dynamic range of four orders of magnitude is achieved with the maximum range over 20 pC and the noise performance of 0.46 fC + 6.4×10{sup −4} fC/pF. -- Highlights: ► A front-end ASIC is developed with a wide dynamic range amplifier. ► The ASIC consists of a CSA, four wave-shaping circuits and pulse-height-to-time converters. ► The dynamic range of four orders of magnitude is achieved with the maximum range over 20 pC.

    A high linearity current mode multiplier/divider (CMM/D) with a wide dynamic range is presented. The proposed CMM/D is based on the voltage—current characteristic of the diode, thus wide dynamic range is achieved. In addition, high linearity is achieved because high accuracy current mirrors are adopted and the output current is insensitive to the temperature and device parameters of the fabrication process. Furthermore, no extra bias current for all input signals is required and thus power saving is realized. With proper selection of establishing the input terminal, the proposed circuit can perform as a multifunction circuit to be operated as a multiplier/divider, without changing its topology. The proposed circuit is implemented in a 0.25 μm BCD process and the chip area is 0.26 × 0.24 mm 2 . The simulation and measurement results show that the maximum static linearity error is ±1.8% and the total harmonic distortion is 0.4% while the input current ranges from 0 to 200 μA.

    Alves, Rômulo Rn; Souto, Wedson Ms

    2011-07-18

    Ancient connections between animals and human are seen in cultures throughout the world in multiple forms of interaction with the local fauna that form the core of Ethnozoology. Historically, ethnozoological publications grew out of studies undertaken in academic areas such as zoology, human ecology, sociology and anthropology--reflecting the interdisciplinary character of this discipline. The rich fauna and cultural diversity found in Brazil, with many different species of animals being used for an extremely wide diversity of purposes by Amerindian societies (as well as the descendents of the original European colonists and African slaves), presents an excellent backdrop for examining the relationships that exist between humans and other animals. This work presents a historical view of ethnozoological research in Brazil and examines its evolution, tendencies, and future perspectives. In summary, literature researches indicated that ethnozoology experienced significant advances in recent years in Brazil, although from a qualitative point of view improvement is still needed in terms of methodological procedures, taxonomic precision, and the use of quantitative techniques. A wide range of methodologies and theories are available in different areas of learning that can be put to good use in ethnozoological approaches if the right questions are asked. The challenges to studying ethnozoology in Brazil are not insignificant, and the tendencies described in the present study may aid in defining research strategies that will maintain the quantitative growth observed in the recent years but likewise foster needed qualitative improvements.

    2017-12-01

    This poster will consider the extent to which students understanding of geoscience are enhanced by interdisciplinary curricular offerings, as well as how teacher instructional practices are influenced in the process. The poster will cite examples from a two programme bilingual International Baccalaureate (IB) world school in Hong Kong where students' opportunities to learn about the world come in a number of forms both within and beyond the mainstream curriculum. The IB Middle Years (IB MYP) and Diploma (IB DP) Programmes encourage interdisciplinary learning. The IB's Approaches to Teaching and Learning (AtTL) provides students and teachers with a framework for best practice for learning how to learn, as well specific teacher practices for the planning and delivery of courses. Most importantly, approaches to teaching which are based on inquiry, focused on conceptual understanding, and rooted in global and local contexts are categorized with approaches to learning which focus on the development of research skills as well as social and self management skills. Through the examination of IB curricular offerings such as the `Interdisciplinary Unit' (IDU) for IB MYP and `Group 4 Science Project' for IB DP, as well as examples taken from the unique `Shuyuan' enrichment programme offered at this school, the poster will consider the interdisciplinary environment from the student and teacher perspective, and the extent to which interdisciplinary learning takes students further in their overall understanding of science and humanities in the real world. In addition, the poster will consider the effect on teacher instructional practices and professional learning needs for schools undertaking interdisciplinary teaching and learning. The poster concludes that for high quality interdisciplinary understanding to take place, these experiences should be planned both vertically and horizontally and collaborative planning for teachers needs to be prioritized. In addition, exploring

  7. Teacher Perspectives of Interdisciplinary Coteaching Relationships in a Clinical Skills Course: A Relational Coordination Theory Analysis.

    2018-01-01

    Phenomenon: Interdisciplinary coteaching has become a popular pedagogic model in medical education, yet there is insufficient research to guide effective practices in this context. Coteaching relationships are not always effective, which has the potential to affect the student experience. The purpose of this study was to explore interdisciplinary coteaching relationships between a physician (MD) and social behavioral scientist (SBS) in an undergraduate clinical skills course. We aimed to gain an in-depth understanding of what teachers perceive as influencing the quality of relationships to begin to construct a framework for collaborative teaching in medical education. A qualitative study was conducted consisting of 12 semistructured interviews (6 MD and 6 SBS) and 2 monodisciplinary focus groups. Sampling was purposive and aimed at maximal variation from among 64 possible faculty. The data were analyzed using the constant comparative method to develop a grounded theory. Five major themes resulted from the analysis that outline a framework for interdisciplinary coteaching: respect, shared goals, shared knowledge and understanding, communication, and complementary pairings. Insights: The first 4 themes align with elements of relational coordination theory, an organizational theory of collaborative practice that describes how work roles interact. The complementary pairings extend this theory from work roles to individuals, with unique identities and personal beliefs and values about teaching. Prior studies on coteaching have not provided a clear linkage to theory. The conceptual framework helps suggest future directions for coteaching research and has practical implications for administrative practices and faculty development. These findings contribute to the sparse research in medical education on interdisciplinary coteaching relationships.

    Domestic livestock grazing occurs in virtually all sagebrush habitats and is a prominent disturbance factor. By affecting habitat condition and trend, grazing influences the resources required by, and thus, the distribution and abundance of sagebrush-obligate wildlife species (for example, sage-grouse Centrocercus spp.). Yet, the risks that livestock grazing may pose to these species and their habitats are not always clear. Although livestock grazing intensity and associated habitat condition may be known in many places at the local level, we have not yet been able to answer questions about use, condition, and trend at the landscape scale or at the range-wide scale for wildlife species. A great deal of information about grazing use, management regimes, and ecological condition exists at the local level (for individual livestock management units) under the oversight of organizations such as the Bureau of Land Management (BLM). However, the extent, quality, and types of existing data are unknown, which hinders the compilation, mapping, or analysis of these data. Once compiled, these data may be helpful for drawing conclusions about rangeland status, and we may be able to identify relationships between those data and wildlife habitat at the landscape scale. The overall objective of our study was to perform a range-wide assessment of livestock grazing effects (and the relevant supporting data) in sagebrush ecosystems managed by the BLM. Our assessments and analyses focused primarily on local-level management and data collected at the scale of BLM grazing allotments (that is, individual livestock management units). Specific objectives included the following: 1. Identify and refine existing range-wide datasets to be used for analyses of livestock grazing effects on sagebrush ecosystems. 2. Assess the extent, quality, and types of livestock grazing-related natural resource data collected by BLM range-wide (i.e., across allotments, districts and regions). 3. Compile and

    2018-06-01

    Full Text Available Using an innovation training project, an interdisciplinary cross-sectional teaching strategy was developed to enhance students’ willingness to comply with the law. Thirty-five business, finance and accounting teachers examined the effects of ethical education on 484 university students’ willingness to comply with corporate law. Ethical education was based on building students’ ethical decisions on three court judgments in the new Spanish Corporate Governance Code. The ethical training was carried out by developing and applying social justice counter arguments. This perspective allowed students to imagine what decisions other person could have taken if they had managed the company ethically. The results suggest that ethics education in higher education can improve the willingness to comply the law. This methodology can be applied to interdisciplinary departments teaching ethics in business, finance and accounting.

    A robust feedforward-feedback controller is proposed for wide-range operations of nuclear reactors. This control structure provides (a) optimized performance over a wide operating range resulting form the feedforward element and (b) guaranteed robust stability and performance resulting from the feedback element. The feedforward control law is synthesized via nonlinear programming, which generates an optimal control sequence over a finite-time horizon under specified constraints. The feedback control is synthesized via the structured singular value μ approach to guarantee robustness in the presence of disturbances and modeling uncertainties. The results of simulation experiments are presented to demonstrate efficacy of the proposed control structure for a large rapid power reduction to avoid unnecessary plant trips

    2016-09-01

    Nailfold capillaroscopy is a method of great diagnostic value in the differential diagnosis of primary versus secondary Raynaud´s phenomenon, of systemic sclerosis versus other so called connective tissue diseases and of additional diagnostic value in other entities. Rheumatologists, dermatologists, and angiologists in Germany have convened in an interdisciplinary working group in which they synergistically combined their expertise to develop a common nomenclature and standards for the technical performance of nailfold capillary microscopy. The article gives an overview of historical and technical aspects of capillaroscopy, morphologic findings, and disease-specific patterns. It also provides a critical appraisal of its significance in the diagnosis and sequelae of these interdisciplinarily-managed diseases including its performance in children and gives an excursion in the potential perspectives of capillaroscopy in less common indications.

    2013-12-01

    Full Text Available Communication is fundamental in scientific practice and an integral part of academic work. The practice of communication cannot be neglected by those who are trying to advance scientific research. Effective means should continuously be identified in order to open channels of communication within and among disciplines, among scientists and between scientists and the general public.[1]The increasing importance of interdisciplinary communication has been pointed out by an increasing number of researchers and scholars, as well as in conferences and roundtables on the subject. Some authors even estimate that "interdisciplinary study represents the future of the university."[2] Since interdisciplinary study is "the most underthought critical, pedagogical and institutional concept in modern academy"[3] it is important to think and reflect, and even do some research, on this concept or notion. Research and practice based reflections with regards to this issue are important especially because the increasing complexity and proliferation of scientific research is generating countless specialties, sub-specialties and sub-sub-specialties, with their respective special languages; which were "created for discrete local areas of research based upon the disconnected branches of science."[4] On the other hand, scientific, technical and societal problems are requiring multi- or inter-disciplinary consideration. Consequently, interdisciplinary communication channels are being needed with urgency, and scientific research should be integrated, not just in the context of its discipline, but also in the context of related disciplines. Much more reflection and research should be done on this issue. Research on adequate research integration and communication is urgently required, i.e. meta-research efforts should be done in order to relate research results in an adequate and more useful way. This meta-research effort might be done in the context of each particular

    This paper describes a divide-by-two injection-locked frequency divider (ILFD) for frequency synthesizers as used in multiband orthogonal frequency division multiplexing (OFDM) ultra-wideband (UWB) systems. By means of dual-injection technique and other conventional tuning techniques, such as DCCA and varactor tuning, the divider demonstrates a wide locking range while consuming much less power. The chip was fabricated in the Jazz 0.18 mum RF CMOS process. The measurement results show that the divider achieves a locking range of 4.85 GHz (6.23 to 11.08 GHz) at an input power of 8 dBm. The core circuit without the test buffer consumes only 3.7 mA from a 1.8 V power supply and has a die area of 0.38 x 0.28 mm{sup 2}. The wide locking range combined with low power consumption makes the ILFD suitable for its application in UWB systems.

The proposed architecture mitigates the reverse-leakage problem in conven- tional, cross-coupled rectifiers without degrading sensitivity. A prototype is designed for UHF RFID applications, and is imple- mented using 0.18 μ m CMOS technology. On-chip measurements demonstrate a sensitivity of − 18 dBm for 1 V output over a 100 k Ω load and a peak RF-to-DC power conversion efficiency of 65%. A conventional, fully cross-coupled rectifier is fabricated along- side for comparison and the proposed rectifier shows more than 2 × increase in dynamic range and a 25% boosting in output voltage than the conventional rectifier

    Ozone concentration in surface anode-directed DBD for wide pressure range (150 - 1300 torr) was experimentally measured. Voltage and pressure effect were investigated. Reduced electric field was measured for anode-directed and cathode-directed SDBD. E/n values in cathode-directed SDBD is higher than in cathode-directed on 50 percent at atmospheric pressure. E/n value increase leads to decrease the rate of oxygen dissociation and Ozone formation at lower pressures. Radiating region thickness of sliding discharge was measured. Typical thickness of radiating zone is 0.4-1.0 mm within pressure range 220-740 torr. It was shown that high-voltage pulsed nanosecond discharge due to high E/n value produces less Ozone with compare to other discharges. Kinetic model was proposed to describe Ozone formation in the pulsed nanosecond SDBD.

    Full Text Available Wearable sensors for detection of human activities have encouraged the development of highly elastic sensors. In particular, to capture subtle and large-scale body motion, stretchable and wide-range strain sensors are highly desired, but still a challenge. Herein, a highly stretchable and transparent stain sensor based on ionic liquids and elastic polymer has been developed. The as-obtained sensor exhibits impressive stretchability with wide-range strain (from 0.1% to 400%, good bending properties and high sensitivity, whose gauge factor can reach 7.9. Importantly, the sensors show excellent biological compatibility and succeed in monitoring the diverse human activities ranging from the complex large-scale multidimensional motions to subtle signals, including wrist, finger and elbow joint bending, finger touch, breath, speech, swallow behavior and pulse wave.

  10. Genetically encoded ratiometric fluorescent thermometer with wide range and rapid response.

    Directory of Open Access Journals (Sweden)

    Masahiro Nakano

    Full Text Available Temperature is a fundamental physical parameter that plays an important role in biological reactions and events. Although thermometers developed previously have been used to investigate several important phenomena, such as heterogeneous temperature distribution in a single living cell and heat generation in mitochondria, the development of a thermometer with a sensitivity over a wide temperature range and rapid response is still desired to quantify temperature change in not only homeotherms but also poikilotherms from the cellular level to in vivo. To overcome the weaknesses of the conventional thermometers, such as a limitation of applicable species and a low temporal resolution, owing to the narrow temperature range of sensitivity and the thermometry method, respectively, we developed a genetically encoded ratiometric fluorescent temperature indicator, gTEMP, by using two fluorescent proteins with different temperature sensitivities. Our thermometric method enabled a fast tracking of the temperature change with a time resolution of 50 ms. We used this method to observe the spatiotemporal temperature change between the cytoplasm and nucleus in cells, and quantified thermogenesis from the mitochondria matrix in a single living cell after stimulation with carbonyl cyanide 4-(trifluoromethoxyphenylhydrazone, which was an uncoupler of oxidative phosphorylation. Moreover, exploiting the wide temperature range of sensitivity from 5°C to 50°C of gTEMP, we monitored the temperature in a living medaka embryo for 15 hours and showed the feasibility of in vivo thermometry in various living species.

  11. Lifetime measurements in the picosecond range: Achievements and Perspectives

    1999-01-01

    This contribution will review the recoil distance method (RDM), its current range of applications as well as future perspectives for the measurement of lifetimes in the picosecond range of excited nuclear levels. Recent Doppler-shift lifetime experiments with large gamma-ray spectrometers have achieved a new level of precision and sensitivity, providing new insights into nuclear structure physics. High precision RDM measurements of near-yrast states in various mass regions have revealed dynamic shape effects beyond the framework of collective models and have also allowed to study the interaction between coexisting shapes. The measurement of lifetimes in superdeformed bands has shown that lifetimes can be measured for nuclear excitations, which are only populated with a few percent of the production cross-section of a nucleus. These experiments have also enabled us to study the mechanism of the decay-out of superdeformed bands. Another example for the need of precise lifetime measurements is the recent verifications of the concept of 'magnetic rotation' in nuclei by the experimental observation of the characteristic drop of B(M1) values as a function of angular momentum. These recent breakthroughs have also opened new perspectives for the use of the RDM technique for more exotic regions of nuclei and nuclear excitations. Here the measurement of lifetimes in neutron rich nuclei, which are not accessible with conventional nuclear reactions using stable beams and targets, is of special interest. Possible experimental approaches and simple estimates for the feasibility of such experiments will be presented. (author)

    2016-04-15

    Although stiffness-controllable substrates have been developed to investigate the effect of stiffness on cell behavior and function, the use of separate substrates with different degrees of stiffness, substrates with a narrow range stiffness gradient, toxicity of residues, different surface composition, complex fabrication procedures/devices, and low cell adhesion are still considered as hurdles of conventional techniques. In this study, a cylindrical polyvinyl alcohol (PVA)/hyaluronic acid (HA) hydrogel with a wide-range stiffness gradient (between ∼20kPa and ∼200kPa) and cell adhesiveness was prepared by a liquid nitrogen (LN2)-contacting gradual freezing-thawing method that does not use any additives or specific devices to produce the stiffness gradient hydrogel. From an in vitro cell culture using the stiffness gradient PVA/HA hydrogel, it was observed that human bone marrow mesenchymal stem cells have favorable stiffness ranges for induction of differentiation into specific cell types (∼20kPa for nerve cell, ∼40kPa for muscle cell, ∼80kPa for chondrocyte, and ∼190kPa for osteoblast). The PVA/HA hydrogel with a wide range of stiffness spectrum can be a useful tool for basic studies related with the stem cell differentiation, cell reprogramming, cell migration, and tissue regeneration in terms of substrate stiffness. It is postulated that the stiffness of the extracellular matrix influences cell behavior. To prove this concept, various techniques to prepare substrates with a stiffness gradient have been developed. However, the narrow ranges of stiffness gradient and complex fabrication procedures/devices are still remained as limitations. Herein, we develop a substrate (hydrogel) with a wide-range stiffness gradient using a gradual freezing-thawing method which does not need specific devices to produce a stiffness gradient hydrogel. From cell culture experiments using the hydrogel, it is observed that human bone marrow mesenchymal stem cells have

    2007-01-01

    A new radiation dose monitor, designated as DARWIN (Dose monitoring system Applicable to various Radiations with Wide energy ranges), has been developed for real-time monitoring of doses in workspaces and surrounding environments of high-energy accelerator facilities. DARWIN is composed of a Phoswitch-type scintillation detector, which consists of liquid organic scintillator BC501A coupled with ZnS(Ag) scintillation sheets doped with 6 Li, and a data acquisition system based on a Digital-Storage-Oscilloscope. DARWIN has the following features: (1) capable of monitoring doses from neutrons, photons and muons with energies from thermal energy to 1 GeV, 150 keV to 100 MeV and 1 MeV to 100 GeV, respectively, (2) highly sensitive with precision and (3) easy to operate with a simple graphical user-interface. The performance of DARWIN was examined experimentally in several radiation fields. The results of the experiments indicated the accuracy and wide response range of DARWIN for measuring dose rates from neutrons, photons and muons with wide energies. It was also found from the experiments that DARWIN enables us to monitor small fluctuations of neutron dose rates near the background level because of its high sensitivity. With these properties, DARWIN will be able to play a very important role for improving radiation safety in high-energy accelerator facilities. (authors)

  18. A method of reflexive balancing in a pragmatic, interdisciplinary and reflexive bioethics.

    Science.gov (United States)

    Ives, Jonathan

    2014-07-01

    In recent years there has been a wealth of literature arguing the need for empirical and interdisciplinary approaches to bioethics, based on the premise that an empirically informed ethical analysis is more grounded, contextually sensitive and therefore more relevant to clinical practice than an 'abstract' philosophical analysis. Bioethics has (arguably) always been an interdisciplinary field, and the rise of 'empirical' (bio)ethics need not be seen as an attempt to give a new name to the longstanding practice of interdisciplinary collaboration, but can perhaps best be understood as a substantive attempt to engage with the nature of that interdisciplinarity and to articulate the relationship between the many different disciplines (some of them empirical) that contribute to the field. It can also be described as an endeavour to explain how different disciplinary approaches can be integrated to effectively answer normative questions in bioethics, and fundamental to that endeavour is the need to think about how a robust methodology can be articulated that successfully marries apparently divergent epistemological and metaethical perspectives with method. This paper proposes 'Reflexive Bioethics' (RB) as a methodology for interdisciplinary and empirical bioethics, which utilizes a method of 'Reflexive Balancing' (RBL). RBL has been developed in response to criticisms of various forms of reflective equilibrium, and is built upon a pragmatic characterization of Bioethics and a 'quasi-moral foundationalism', which allows RBL to avoid some of the difficulties associated with RE and yet retain the flexible egalitarianism that makes it intuitively appealing to many. © 2013 John Wiley & Sons Ltd.

  19. On the Criticality of Interdisciplinary Communications for Continued Scholarly Research, and the Potential Applicability of the Case Studies Methodology (Invited Paper

    Directory of Open Access Journals (Sweden)

    Jeffrey A. Dunne

    2014-12-01

    Full Text Available Increasing the prevalence and effectiveness of interdisciplinary communication/collaboration is not a simple matter, but has significant benefits to offer. Ironically, one of the greatest challenges, namely the diversity in perspectives and contributor nature, provides one of its most significant payoffs. Diversity in backgrounds, skills, knowledge, and approaches promotes ingenuity and creativity, and is a powerful source of innovation. But perhaps more importantly, effective interdisciplinary collaboration is essential for applying forefront research to the most challenging societal problems. This reflection paper describes a line of reasoning for why effective interdisciplinary collaboration skills have emerged as an essential, and yet largely neglected, requirement for maintaining the development and relevance of scholarly research. It outlines challenges that must be overcome in meeting this requirement, important factors for addressing those challenges, and concludes by discussing the applicability of the case methodology, as introduced at the 2014 International Multi-Conference on Complexity, Informatics and Cybernetics, as a mechanism for training people to become effective participants in interdisciplinary endeavors.

    As the front-end preamplifiers in optical receivers, transimpedance amplifiers (TIAs) are commonly required to have a high gain and low input noise to amplify the weak and susceptible input signal. At the same time, the TIAs should possess a wide dynamic range (DR) to prevent the circuit from becoming saturated by high input currents. Based on the above, this paper presents a CMOS transimpedance amplifier with high gain and a wide DR for 2.5 Gbit/s communications. The TIA proposed consists of a three-stage cascade pull push inverter, an automatic gain control circuit, and a shunt transistor controlled by the resistive divider. The inductive-series peaking technique is used to further extend the bandwidth. The TIA proposed displays a maximum transimpedance gain of 88.3 dBΩ with the −3 dB bandwidth of 1.8 GHz, exhibits an input current dynamic range from 100 nA to 10 mA. The output voltage noise is less than 48.23 nV/√Hz within the −3 dB bandwidth. The circuit is fabricated using an SMIC 0.18 μm 1P6M RFCMOS process and dissipates a dc power of 9.4 mW with 1.8 V supply voltage. (semiconductor integrated circuits)

  1. When Augmented Reality Met Art: Lessons Learned from Researcher–Artist Interdisciplinary Work

    Directory of Open Access Journals (Sweden)

    2018-04-01

    Full Text Available Over the last few years, Augmented Reality (AR technology has quickly evolved and today there is commercial software and hardware that allow the creation of AR experiences. However, it might still be cumbersome to create rich AR experiences without a deep knowledge of the technology. Artists have collaborated with IT experts during the last few years in order to enhance artistic pieces embedding AR technology, leading to the emergence of interesting collaborations between artists and engineers, computer scientists, architects, etc. The resulting works can be referred as AR Art. However, the interdisciplinary work behind these collaborations is usually not addressed. The aim of this paper is to review some of the reported AR Art work since the AR term was first coined in 1990, focusing on collaborations between different disciplines, especially during the early years, where art and technology became one. Additionally, the author reports her own experience in contributing to AR Art from an interdisciplinary perspective.

  2. HESS Opinions "Integration of groundwater and surface water research: an interdisciplinary problem?"

    Science.gov (United States)

    Barthel, R.

    2014-07-01

    Today there is a great consensus that water resource research needs to become more holistic, integrating perspectives of a large variety of disciplines. Groundwater and surface water (hereafter: GW and SW) are typically identified as different compartments of the hydrological cycle and were traditionally often studied and managed separately. However, despite this separation, these respective fields of study are usually not considered to be different disciplines. They are often seen as different specializations of hydrology with a different focus yet similar theory, concepts, and methodology. The present article discusses how this notion may form a substantial obstacle in the further integration of GW and SW research and management. The article focuses on the regional scale (areas of approximately 103 to 106 km2), which is identified as the scale where integration is most greatly needed, but ironically where the least amount of fully integrated research seems to be undertaken. The state of research on integrating GW and SW research is briefly reviewed and the most essential differences between GW hydrology (or hydrogeology, geohydrology) and SW hydrology are presented. Groundwater recharge and baseflow are used as examples to illustrate different perspectives on similar phenomena that can cause severe misunderstandings and errors in the conceptualization of integration schemes. The fact that integration of GW and SW research on the regional scale necessarily must move beyond the hydrological aspects, by collaborating with the social sciences and increasing the interaction between science and society in general, is also discussed. The typical elements of an ideal interdisciplinary workflow are presented and their relevance with respect to the integration of GW and SW is discussed. The overall conclusions are that GW hydrology and SW hydrogeology study rather different objects of interest, using different types of observation, working on different problem settings

    This study describes the effects of interdisciplinary leadership training on a retrospective cohort (2001-2009) of the University of North Carolina MCH Leadership Education in Neurodevelopmental and Related Disabilities (UNC-CH LEND) program, including LEND graduates who were selected to participate in a focused Interdisciplinary Leadership Development Program (ILDP) in addition to their LEND training. Specifically, the study examined graduates' reports of the relationship between LEND training and their attitudes/beliefs about interdisciplinary practice, as well as their reported use of interdisciplinary skills in their post-fellowship practice settings. Using a post-test design, participants in the LEND and ILDP programs were contacted to complete an on-line survey. Using a Conceptual Model guided by EvaluLEAD, respondents were asked to rate the influence of the UNC-LEND training program on their attitudes/beliefs and skills using a 5-point Likert scale, as well as through open-ended descriptions. The 49 LEND respondents represented a 56% overall response rate from years 2001-2009. ILDP participants reported greater agreement with interdisciplinary attitudes/beliefs and more frequent use of interdisciplinary skills than did the non-participants. Graduates of LEND as well as ILDP reported the influence of training through a range of qualitative responses. Response examples highlight the influence of LEND training to promote outcomes at the individual, organizational and systems level. Findings from this study illustrate that MCHB funded LEND training has a strong influence on the future employment and interdisciplinary practices of graduates for the MCH workforce as well as services for individuals with developmental disabilities, their families and systems of care.

    Vroman, Kerryellen; Kovacich, Joann

    2002-05-01

    The benefit of experience, tempered with the wisdom of hindsight and 5 years of text-based, asynchronous, computer-mediated, interdisciplinary team communications, provides the energy, insights and data shared in this article. Through the theoretical lens of group dynamics and the epistemology of interdisciplinary teaming, we analyze the interactions of a virtual interdisciplinary team to provide an understanding and appreciation of collaborative interdisciplinary communication in the context of interactive technologies. Whilst interactive technologies may require new patterns of language similar to that of learning a foreign language, what is communicated in the interdisciplinary team process does not change. Most important is the recognition that virtual teams, similar to their face-to-face counterparts, undergo the same challenges of interdisciplinary teaming and group developmental processes of formation: forming, storming, norming, performing, and transforming. After examining these dynamics of communication and collaboration in the context of the virtual team, the article concludes with guidelines facilitating interdisciplinary team computer-mediated communication.

  7. Organizational Influences on Interdisciplinary Interactions during Research and Design of Large-Scale Complex Engineered Systems

    The design of large-scale complex engineered systems (LaCES) such as an aircraft is inherently interdisciplinary. Multiple engineering disciplines, drawing from a team of hundreds to thousands of engineers and scientists, are woven together throughout the research, development, and systems engineering processes to realize one system. Though research and development (R&D) is typically focused in single disciplines, the interdependencies involved in LaCES require interdisciplinary R&D efforts. This study investigates the interdisciplinary interactions that take place during the R&D and early conceptual design phases in the design of LaCES. Our theoretical framework is informed by both engineering practices and social science research on complex organizations. This paper provides preliminary perspective on some of the organizational influences on interdisciplinary interactions based on organization theory (specifically sensemaking), data from a survey of LaCES experts, and the authors experience in the research and design. The analysis reveals couplings between the engineered system and the organization that creates it. Survey respondents noted the importance of interdisciplinary interactions and their significant benefit to the engineered system, such as innovation and problem mitigation. Substantial obstacles to interdisciplinarity are uncovered beyond engineering that include communication and organizational challenges. Addressing these challenges may ultimately foster greater efficiencies in the design and development of LaCES and improved system performance by assisting with the collective integration of interdependent knowledge bases early in the R&D effort. This research suggests that organizational and human dynamics heavily influence and even constrain the engineering effort for large-scale complex systems.

    The present invention has a function of reliably switching measuring values between a pulse method and a Cambel method even if noise level and saturated level are fluctuated. That is, a proportional range judging means always monitors neutron flux measuring values in a start-up region and neutron flux measuring values in an intermediate power region, so that the proportional range is detected depending on whether the difference or a variation coefficient of both of the measured values is constant or not. A switching value determining means determines a switching value by the result of judgement of the proportional range judging means. A selection/output means selects and outputs measuring signals at a neutron flux level in the start-up region or the intermediate power region by the output of the switching value determining means. With such procedures, since the measuring value is switched after confirming that arrival at the proportional range where the difference or a variation coefficient of the measured value between the pulse processing method and the measured value by the Cambel method is constant, an accurate neutron flux level containing neither noise level nor saturated level can be outputted.

  12. Modal density of rectangular structures in a wide frequency range

    Science.gov (United States)

    Parrinello, A.; Ghiringhelli, G. L.

    2018-04-01

    A novel approach to investigate the modal density of a rectangular structure in a wide frequency range is presented. First, the modal density is derived, in the whole frequency range of interest, on the basis of sound transmission through the infinite counterpart of the structure; then, it is corrected by means of the low-frequency modal behavior of the structure, taking into account actual size and boundary conditions. A statistical analysis reveals the connection between the modal density of the structure and the transmission of sound through its thickness. A transfer matrix approach is used to compute the required acoustic parameters, making it possible to deal with structures having arbitrary stratifications of different layers. A finite element method is applied on coarse grids to derive the first few eigenfrequencies required to correct the modal density. Both the transfer matrix approach and the coarse grids involved in the finite element analysis grant high efficiency. Comparison with alternative formulations demonstrates the effectiveness of the proposed methodology.

    We live in a world where biophysical and social processes are tightly coupled. Hydrologic systems change in response to a variety of natural and human forces such as climate variability and change, water use and water infrastructure, and land cover change. In turn, changes in hydrologic systems impact socioeconomic, ecological, and climate systems at a number of scales, leading to a coevolution of these interlinked systems. The Harvard Water Program, Hydrosociology, Integrated Water Resources Management, Ecohydrology, Hydromorphology, and Sociohydrology were all introduced to provide distinct, interdisciplinary perspectives on water problems to address the contemporary dynamics of human interaction with the hydrosphere and the evolution of the Earth’s hydrologic systems. Each of them addresses scientific, social, and engineering challenges related to how humans influence water systems and vice versa. There are now numerous examples in the literature of how holistic approaches can provide a structure and vision of the future of hydrology. We review selected examples, which taken together, describe the type of theoretical and applied integrated hydrologic analyses and associated curricular content required to address the societal issue of water resources sustainability. We describe a modern interdisciplinary science of hydrology needed to develop an in-depth understanding of the dynamics of the connectedness between human and natural systems and to determine effective solutions to resolve the complex water problems that the world faces today. Nearly, every theoretical hydrologic model introduced previously is in need of revision to accommodate how climate, land, vegetation, and socioeconomic factors interact, change, and evolve over time.

    The complex relationship between globalization and health calls for research from many disciplinary and methodological perspectives. This editorial gives an overview of the content trajectory of the interdisciplinary journal 'Globalization and Health' over the first six years of production, 2005 to 2010. The findings show that bio-medical and population health perspectives have been dominant but that social science perspectives have become more evident in recent years. The types of paper published have also changed, with a growing proportion of empirical studies. A special issue on 'Health systems, health economies and globalization: social science perspectives' is introduced, a collection of contributions written from the vantage points of economics, political science, psychology, sociology, business studies, social policy and research policy. The papers concern a range of issues pertaining to the globalization of healthcare markets and governance and regulation issues. They highlight the important contribution that can be made by the social sciences to this field, and also the practical and methodological challenges implicit in the study of globalization and health.

    Many patients treated on trauma surgery wards are geriatric trauma patients. To improve treatment of these often multimorbid patients, various interdisciplinary treatment concepts have been established in Germany between trauma surgeons and geriatricians. The aim of this study was to evaluate the dissemination and the impact of the different orthogeriatric treatment concepts for geriatric trauma in Germany. Material and methods In March and April 2014 an electronic questionnaire for assessing the interdisciplinary treatment of geriatric trauma patients was sent to 691 medical directors of trauma surgery departments in Germany. A total of 259 (37 %) fully answered questionnaires could be analyzed. The analysis revealed that 70 % of all responding trauma surgery departments had an orthogeriatric treatment cooperation. Most of them reported having patient discharge agreements to geriatric rehabilitation facilities (59 %). Geriatric counseling services were reported by 39 % while 24 % reported having regular interdisciplinary visits and orthogeriatric wards were available in 13 %. The need for orthogeriatric services was considered to be high by 79 % of the participants and benefits especially for the patients were expected. These expectations were largely fulfilled. More than 70 % of respondents planned to intensify the orthogeriatric cooperation. In this context difficulties were seen in the lack of personnel resources, especially in a lack of geriatricians. The results of this survey underline the impact and the positive experiences in orthogeriatric services. Solutions have to be found to address the emerging problem of capacity constraints.

    Rietmann, Felix; Schildmann, Mareike; Arni, Caroline; Cook, Daniel Thomas; Giuriato, Davide; Göhlsdorf, Novina; Muigai, Wangui

    2017-03-01

    This round table discussion takes the diversity of discourse and practice shaping modern knowledge about childhood as an opportunity to engage with recent historiographical approaches in the history of science. It draws attention to symmetries and references among scientific, material, literary and artistic cultures and their respective forms of knowledge. The five participating scholars come from various fields in the humanities and social sciences and allude to historiographical and methodological questions through a range of examples. Topics include the emergence of children's rooms in US consumer magazines, research on the unborn in nineteenth-century sciences of development, the framing of autism in nascent child psychiatry, German literary discourses about the child's initiation into writing, and the sociopolitics of racial identity in the photographic depiction of African American infant corpses in the early twentieth century. Throughout the course of the paper, childhood emerges as a topic particularly amenable to interdisciplinary perspectives that take the history of science as part of a broader history of knowledge.

    1998-05-01

    The departments of Medical Psychology, Psychosomatics and Psychotherapy developed an interdisciplinary longitudinal curriculum in order to coach medical students for the whole length of their medical education. Experiences from the first four undergraduate semesters are reported. 46 students (33 females, 13 males), mean age 22.3 +/- 2.6 years, attended 60 hours of interdisciplinary group sessions. Frequent motives to join the course were interest in psychosocial disciplines and relevant previous experience. The students expected to benefit from this project in their study, their future practice as a physician, and in their personal development. Important educational goals that could be attained were the adoption of a patient-centred view in medicine as well as strengthening of the students' critical capacities and sensitivity. The students especially appreciated the possibility of group discussions and the opportunity to participate actively in the course. Based on a critical review of the evaluation, the possibility of a transfer of our model is considered and perspectives for the future are developed.

    CERN Document Server

    Bruckstein, Alfred; Maragos, Petros; Wuhrer, Stefanie

    2016-01-01

    This book presents recent advances in the field of shape analysis. Written by experts in the fields of continuous-scale shape analysis, discrete shape analysis and sparsity, and numerical computing who hail from different communities, it provides a unique view of the topic from a broad range of perspectives. Over the last decade, it has become increasingly affordable to digitize shape information at high resolution. Yet analyzing and processing this data remains challenging because of the large amount of data involved, and because modern applications such as human-computer interaction require real-time processing. Meeting these challenges requires interdisciplinary approaches that combine concepts from a variety of research areas, including numerical computing, differential geometry, deformable shape modeling, sparse data representation, and machine learning. On the algorithmic side, many shape analysis tasks are modeled using partial differential equations, which can be solved using tools from the field of n...

    2013-05-10

    Interdisciplinary team work is increasingly prevalent, supported by policies and practices that bring care closer to the patient and challenge traditional professional boundaries. To date, there has been a great deal of emphasis on the processes of team work, and in some cases, outcomes. This study draws on two sources of knowledge to identify the attributes of a good interdisciplinary team; a published systematic review of the literature on interdisciplinary team work, and the perceptions of over 253 staff from 11 community rehabilitation and intermediate care teams in the UK. These data sources were merged using qualitative content analysis to arrive at a framework that identifies characteristics and proposes ten competencies that support effective interdisciplinary team work. Ten characteristics underpinning effective interdisciplinary team work were identified: positive leadership and management attributes; communication strategies and structures; personal rewards, training and development; appropriate resources and procedures; appropriate skill mix; supportive team climate; individual characteristics that support interdisciplinary team work; clarity of vision; quality and outcomes of care; and respecting and understanding roles. We propose competency statements that an effective interdisciplinary team functioning at a high level should demonstrate.

    The digital integration method based on using high-speed precision analog-to-digital converters (ADC) has become widely used over the recent years. The paper analyzes the limitations of this method that are caused by the signal properties, ADC sampling rate and noise spectral density of the ADC signal path. This analysis allowed creating digital integrators with accurate synchronization and achieving an integration error of less than 10 −5 in the time range from microseconds to tens of seconds. The structure of the integrator is described and its basic parameters are presented. The possibilities of different ADC chips in terms of their applicability to digital integrators are discussed. A comparison with other integrating devices is presented.

    Conserving animals beyond protected areas is critical because even the largest reserves may be too small to maintain viable populations for many wide-ranging species. Identification of landscape features that will promote persistence of a diverse array of species is a high priority, particularly, for protected areas that reside in regions of otherwise extensive habitat loss. This is the case for Emas National Park, a small but important protected area located in the Brazilian Cerrado, the world's most biologically diverse savanna. Emas Park is a large-mammal global conservation priority area but is too small to protect wide-ranging mammals for the long-term and conserving these populations will depend on the landscape surrounding the park. We employed novel, noninvasive methods to determine the relative importance of resources found within the park, as well as identify landscape features that promote persistence of wide-ranging mammals outside reserve borders. We used scat detection dogs to survey for five large mammals of conservation concern: giant armadillo (Priodontes maximus), giant anteater (Myrmecophaga tridactyla), maned wolf (Chrysocyon brachyurus), jaguar (Panthera onca), and puma (Puma concolor). We estimated resource selection probability functions for each species from 1,572 scat locations and 434 giant armadillo burrow locations. Results indicate that giant armadillos and jaguars are highly selective of natural habitats, which makes both species sensitive to landscape change from agricultural development. Due to the high amount of such development outside of the Emas Park boundary, the park provides rare resource conditions that are particularly important for these two species. We also reveal that both woodland and forest vegetation remnants enable use of the agricultural landscape as a whole for maned wolves, pumas, and giant anteaters. We identify those features and their landscape compositions that should be prioritized for conservation, arguing

    Earth system science in the classroom is the fertile crucible linking science with societal needs for local, national and global sustainability. The interdisciplinary dimension requires fruitful cooperation among departments, schools and colleges within universities and among the universities and the nation's laboratories and agencies. Teaching and learning requires content which brings together the basic and applied sciences with mathematics and technology in addressing societal challenges of the coming decades. Over the past decade remarkable advances have emerged in information technology, from high bandwidth Internet connectivity to raw computing and visualization power. These advances which have wrought revolutionary capabilities and resources are transforming teaching and learning in the classroom. With the launching of NASA's Earth Observing System (EOS) the amount and type of geophysical data to monitor the Earth and its climate are increasing dramatically. The challenge remains, however, for skilled scientists and educators to interpret this information based upon sound scientific perspectives and utilize it in the classroom. With an increasing emphasis on the application of data gathered, and the use of the new technologies for practical benefit in the lives of ordinary citizens, there comes the even more basic need for understanding the fundamental state, dynamics, and complex interdependencies of the Earth system in mapping valid and relevant paths to sustainability. Technology and data in combination with the need to understand Earth system processes and phenomena offer opportunities for new and productive partnerships between researchers and educators to advance the fundamental science of the Earth system and in turn through discovery excite students at all levels in the classroom. This presentation will discuss interdisciplinary partnership opportunities for educators and researchers at the undergraduate and graduate levels.

    The goal of this report is to discuss educational approaches for bridging the different perspectives of the physiological and mathematical disciplines. These approaches can enhance the learning experience for physiology, medical, and mathematics students and simultaneously act to stimulate mathematical/physiological/clinical interdisciplinary research. While physiology education incorporates mathematics, via equations and formulas, it does not typically provide a foundation for interdisciplinary research linking mathematics and physiology. Here, we provide insights and ideas derived from interdisciplinary seminars involving mathematicians and physiologists that have been conducted over the last decade. The approaches described here can be used as templates for giving physiology and medical students insights into how sophisticated tools from mathematics can be applied and how the disciplines of mathematics and physiology can be integrated in research, thereby fostering a foundation for interdisciplinary collaboration. These templates are equally applicable to linking mathematical methods with other life and health sciences in the educational process.

    InTeGrate materials focus on societal grand challenges, sustainability, and interdisciplinary problems through developing geoscientific habits of mind, the use of credible data, and systems thinking. The materials are freely available 2-3 week modules and courses that allow instructors to focus on a wide variety of topics from regulating carbon emissions, changing biosphere, and storms and community resilience to environmental justice, ocean sustainability, and humans' dependence on mineral resources, integrating a variety of relevant interdisciplinary activities throughout. Presented with interdisciplinary approaches, students learn with tools to integrate engineering, policy, economics, and social aspects with the science to address the challenges. Students' ability to apply interdisciplinary approaches to address sustainability problems is made visible through the essays they write as a part of the materials assessment. InTeGrate modules have been adopted and implemented by faculty members interested in sustainability themes and innovative pedagogy, and have reached more than 50,000 students in all 50 states, Puerto Rico, India, and Micronesia. Student data were collected from 533 assessment essays in 57 undergraduate classes. The essays required students to describe a global challenge in an interdisciplinary manner through identifying scientific implications, and connecting it to economic, social and policy decisions. Students also completed a second essay assessing their systems thinking ability, a geoscience literacy exam (GLE), and demographic and attitudinal surveys. Scores for students enrolled in classes using InTeGrate materials were compared to scores from students in similar classes that did not use InteGrate materials. The InTeGrate and control groups had equivalent GLE scores and demographic characteristics. Essay scores for students in InTeGrate introductory or majors courses outperformed students in comparable level control courses as measured by

    Full Text Available Interdisciplinary researchers and educators, as community members, creators of knowledge, and environmental activists and practitioners, have a responsibility to build a bridge between community practice, academic scholarship, and professional contributions aimed at establishing environmental sustainability. In this paper, I focus on an undervalued area of environmental politics, practices, and often unarticulated assumptions which underlie human–environmental relations. This article challenges interdisciplinary studies that are not connected with practice by reconfiguring the meaning of a community-based, interdisciplinary approach. Drawing from works by Foucault, Latour, and Haraway, this paper first shows how to reconfigure the meaning of an interdisciplinary approach. Second, using Bourdieu and Brightman’s ethnographic studies as a framework, the paper situates practice as central to our efforts to deconstruct and replace current interdisciplinary initiatives with a practice-based approach. Through a practice-based interdisciplinary approach (PIA, environmental educators and researchers gain an awareness of and learn to make an investment in sustainable communities. As teams of environmental researchers practising in the local community, they are meaningfully involved with the community, with each other, and with the environment.

    Our purpose in this paper is to build a case for utilizing interdisciplinary science to enhance the management of parks and protected areas. We suggest that interdisciplinary science is necessary for dealing with the complex issues of contemporary resource management, and that using the best available integrated scientific information be embraced and supported at all levels of agencies that manage parks and protected areas. It will take the commitment of park managers, scientists, and agency leaders to achieve the goal of implementing the results of interdisciplinary science into park management. Although such calls go back at least several decades, today interdisciplinary science is sporadically being promoted as necessary for supporting effective protected area management(e.g., Machlis et al. 1981; Kelleher and Kenchington 1991). Despite this history, rarely has "interdisciplinary science" been defined, its importance explained, or guidance provided on how to translate and then implement the associated research results into management actions (Tress et al. 2006; Margles et al. 2010). With the extremely complex issues that now confront protected areas (e.g., climate change influences, extinctions and loss of biodiversity, human and wildlife demographic changes, and unprecedented human population growth) information from more than one scientific discipline will need to be brought to bear in order to achieve sustained management solutions that resonate with stakeholders (Ostrom 2009). Although interdisciplinary science is not the solution to all problems, we argue that interdisciplinary research is an evolving and widely supported best practice. In the case of park and protected area management, interdisciplinary science is being driven by the increasing recognition of the complexity and interconnectedness of human and natural systems, and the notion that addressing many problems can be more rapidly advanced through interdisciplinary study and analysis.

    Laser ranging systems now managed by the NASA Dynamics of the Solid Earth (DOSE) and operated by the Bendix Field Engineering Corporation, the University of Hawaii, and the University of Texas have produced a wealth on interdisciplinary scientific data over the last three decades. Despite upgrades to the most of the ranging station subsystems, the control computers remain a mix of 1970's vintage minicomputers. These encompass a wide range of vendors, operating systems, and languages, making hardware and software support increasingly difficult. Current technology allows replacement of controller computers at a relatively low cost while maintaining excellent processing power and a friendly operating environment. The new controller systems are now being designed using IBM-PC-compatible 80486-based microcomputers, a real-time Unix operating system (LynxOS), and X-windows/Motif IB, and serial interfaces have been chosen. This design supports minimizing short and long term costs by relying on proven standards for both hardware and software components. Currently, the project is in the design and prototyping stage with the first systems targeted for production in mid-1993.

  11. Interdisciplinary Adventures in Perceptual Ecology

    Science.gov (United States)

    Bocast, Christopher S.

    A portfolio dissertation that began as acoustic ecology and matured into perceptual ecology, centered on ecomusicology, bioacoustics, and translational audio-based media works with environmental perspectives. The place of music in Western eco-cosmology through time provides a basis for structuring an environmental history of human sound perception. That history suggests that music may stabilize human mental activity, and that an increased musical practice may be essential for the human project. An overview of recent antecedents preceding the emergence of acoustic ecology reveals structural foundations from 20th century culture that underpin modern sound studies. The contextual role that Aldo Leopold, Jacob von Uexkull, John Cage, Marshall McLuhan, and others played in anticipating the development of acoustic ecology as an interdiscipline is detailed. This interdisciplinary aspect of acoustic ecology is defined and defended, while new developments like soundscape ecology are addressed, though ultimately sound studies will need to embrace a broader concept of full-spectrum "sensory" or "perceptual" ecology. The bioacoustic fieldwork done on spawning sturgeon emphasized this necessity. That study yielded scientific recordings and spectrographic analyses of spawning sounds produced by lake sturgeon, Acipenser fulvescens, during reproduction in natural habitats in the Lake Winnebago watershed in Wisconsin. Recordings were made on the Wolf and Embarrass River during the 2011-2013 spawning seasons. Several specimens were dissected to investigate possible sound production mechanisms; no sonic musculature was found. Drumming sounds, ranging from 5 to 7 Hz fundamental frequency, verified the infrasonic nature of previously undocumented "sturgeon thunder". Other characteristic noises of sturgeon spawning including low-frequency rumbles and hydrodynamic sounds were identified. Intriguingly, high-frequency signals resembling electric organ discharges were discovered. These

    Full Text Available We discuss conceptual framework, operational perspective and political-institutional features of the Interdisciplinary Bachelor Degree (BI implementation in the Federal University of Bahia, between 2009 and 2012, as compared to existing university education models which, until then, only offered disciplinary professional courses. We analyze narratives of key agents of the process, three UFBA teachers who performed administrative functions, and a BI student, engaged in the student movement. We have concluded that the perspective for the BI to become the first cycle at UFBA is on hold; support and resistance movements have accompanied it, suggesting large institutional challenges. However, the experience has led to a vigorous revision of rules and regulations naturalized for a long time and enabled reflections on the traditional concept of university education in Brazil.

    Analysis of data obtained during the spring 2013 commissioning of the new 4.5 K refrigeration system at Jefferson Lab (JLab) for the 12 GeV upgrade indicated a wide capacity range with good efficiency and minimal operator interaction. Testing also showed that the refrigerator required higher liquid nitrogen (LN) consumption for its pre-cooler than anticipated by the design. This does not affect the capacity of the refrigerator, but it does result in an increased LN utility cost. During the summer of 2015 the modifications were implemented by the cold box manufacturer, according to a design similar to the JLab 12 GeV cold box specification. Subsequently, JLab recommissioned the cold box and performed extensive performance testing, ranging from 20% to 100% of the design maximum capacity, and in various modes of operation, ranging from pure refrigeration, pure liquefaction, half-and-half mix mode and at selected design modes using the Floating Pressure - Ganni Cycle. The testing demonstrated that the refrigerator system has a good and fairly constant performance over a wide capacity range and different modes of operation. It also demonstrated the modifications resulted in a LN consumption that met the design for the pure refrigeration mode (which is the most demanding) and was lower than the design for the nominal and maximum capacity modes. In addition, a pulsed-load test, similar to what is expected for cryogenic systems supporting fusion experiments, was conducted to observe the response using the Floating Pressure - Ganni Cycle, which was stable and robust. This paper will discuss the results and analysis of this testing pertaining to the LN consumption, the system efficiency over a wide range of capacity and different modes and the behaviour of the system to a pulsed load.

    We examine the clustering of quasars over a wide luminosity range, by utilizing 901 quasars at \\overline{z}_phot˜ 3.8 with -24.73 Strategic Program (HSC-SSP) S16A Wide2 date release and 342 more luminous quasars at 3.4 Digital Sky Survey that fall in the HSC survey fields. We measure the bias factors of two quasar samples by evaluating the cross-correlation functions (CCFs) between the quasar samples and 25790 bright z ˜ 4 Lyman break galaxies in M1450 < -21.25 photometrically selected from the HSC dataset. Over an angular scale of 10.0" to 1000.0", the bias factors are 5.93+1.34-1.43 and 2.73+2.44-2.55 for the low- and high-luminosity quasars, respectively, indicating no significant luminosity dependence of quasar clustering at z ˜ 4. It is noted that the bias factor of the luminous quasars estimated by the CCF is smaller than that estimated by the auto-correlation function over a similar redshift range, especially on scales below 40.0". Moreover, the bias factor of the less-luminous quasars implies the minimal mass of their host dark matter halos is 0.3-2 × 1012 h-1 M⊙, corresponding to a quasar duty cycle of 0.001-0.06.

    Increasingly, national programs and leaders are looking at interdisciplinary collaborations as essential to future research. Twelve years ago, the National Institutes of Health (NIH) Office of Research on Women's Health (ORWH) developed and implemented the Building Interdisciplinary Research Careers in Women's Health (BIRCWH) K12 program to focus on interdisciplinary mentored career development for junior faculty in women's health research. We applied a mixed-methods approach using an electronic survey and in-person presentations and discussions to understand best practices and lessons learned for interdisciplinary mentoring across BIRCWH K12 program leaders. We received responses from all 29 active BIRCWH programs. Factors associated with success included ensuring sufficient protected time for regular (weekly or biweekly) mentoring; mentors promoting the research independence of the Scholar; a team mentoring approach, including career as well as content mentors; and explicit and clear expectations outlined between the Scholar and mentor. The majority of programs conduct formal evaluations of mentorship, and 79% of programs offer training in mentorship for either Scholars, mentors, or both. This article presents program leaders' best practices, challenges, and lessons learned from mentoring junior faculty who are conducting women's health research, whether basic, clinical, behavioral, translational, or health services research, using an interdisciplinary mentoring approach.

  16. Autonomous Vehicles Have a Wide Range of Possible Energy Impacts (Poster)

    Energy Technology Data Exchange (ETDEWEB)

    Brown, A.; Repac, B.; Gonder, J.

    2013-07-01

    This poster presents initial estimates of the net energy impacts of automated vehicles (AVs). Automated vehicle technologies are increasingly recognized as having potential to decrease carbon dioxide emissions and petroleum consumption through mechanisms such as improved efficiency, better routing, lower traffic congestion, and by enabling advanced technologies. However, some effects of AVs could conceivably increase fuel consumption through possible effects such as longer distances traveled, increased use of transportation by underserved groups, and increased travel speeds. The net effect on petroleum use and climate change is still uncertain. To make an aggregate system estimate, we first collect best estimates for the energy impacts of approximately ten effects of AVs. We then use a modified Kaya Identity approach to estimate the range of aggregate effects and avoid double counting. We find that depending on numerous factors, there is a wide range of potential energy impacts. Adoption of automated personal or shared vehicles can lead to significant fuel savings but has potential for backfire.

    Several years of measured data on global and diffuse radiation and sunshine duration for 40 widely spread locations in the latitude range 36° S to 60° N are used to develop and test models for estimating monthly-mean, daily, diffuse radiation on horizontal surfaces. Applicability of the clearness-index (K) and sunshine fraction (SSO) models for diffuse estimation and the effect of combining several variables into a single multilinear equation are tested. Correlations connecting the diffuse to global fraction (HdH) with K and SSO predict Hd values more accurately than their separate use. Among clearness-index and sunshine-fraction models, SSO models are found to have better accuracy if correlations are developed for wide latitude ranges. By including a term for declinations in the correlation, the accuracy of the estimated data can be marginally improved. The addition of latitude to the equation does not help to improve the accuracy further. (author)

    Full Text Available Understanding complex socio-environmental problems requires specialists from multiple disciplines to integrate research efforts. Programs such as the National Science Foundation's Integrative Graduate Education and Research Traineeship facilitate integrated research efforts and change the way academic institutions train future leaders and scientists. The University of Idaho and the Tropical Agricultural Research and Higher Education Center in Costa Rica collaborate on a joint research program focusing on biodiversity conservation and sustainable production in fragmented landscapes. We first present a spectrum of integration ranging from disciplinary to transdisciplinary across seven aspects of the research process. We then describe our experiences and lessons learned conducting interdisciplinary graduate student team research. Using our program as a case study, we examine the individual, disciplinary, and programmatic bridges and barriers to conducting interdisciplinary research that emerged during our student team research projects. We conclude with a set of recommendations for exploiting the bridges and overcoming the barriers to conducting interdisciplinary research, especially as part of graduate education programs.

  19. An interdisciplinary perspective on industrial energy efficiency

    International Nuclear Information System (INIS)

    Palm, Jenny; Thollander, Patrik

    2010-01-01

    This paper combines engineering and social science approaches to enhance our understanding of industrial energy efficiency and broaden our perspective on policy making in Europe. Sustainable development demands new strategies, solutions, and policy-making approaches. Numerous studies of energy efficiency potential state that cost-effective energy efficiency technologies in industry are not always implemented for various reasons, such as lack of information, procedural impediments, and routines not favoring energy efficiency. Another reason for the efficiency gap is the existence of particular values, unsupportive of energy efficiency, in the dominant networks of a branch of trade. Analysis indicates that different sectors of rather closed communities have established their own tacit knowledge, perceived truths, and routines concerning energy efficiency measures. Actors in different industrial sectors highlight different barriers to energy efficiency and why cost-effective energy efficiency measures are not being implemented. The identified barriers can be problematized in relation to the social context to understand their existence and how to resolve them.

    To qualitatively improve the data obtained in asymmetry measurements of scattering experiments the figure of merit (FOM) plays a major role and can reduce the data acquisition time when a certain precision in the measurement is needed. One of the defining factors for the improvement of the polarised experiment lies in the target choice and preparation, in particular the method employed to introduce the paramagnetic defects for the use of dynamic nuclear polarisation (DNP). To this end the Polarized Target Group in Bonn has developed a wide range temperature cryostat for the irradiation of potential target materials in which materials can be irradiated to varying doses at specified temperatures. The stable irradiation temperature of the materials can be controlled to within {+-}1 K over a range of 90 K

  2. Modelling seasonal habitat suitability for wide-ranging species: Invasive wild pigs in northern Australia.

    Directory of Open Access Journals (Sweden)

    Jens G Froese

    Full Text Available Invasive wildlife often causes serious damage to the economy and agriculture as well as environmental, human and animal health. Habitat models can fill knowledge gaps about species distributions and assist planning to mitigate impacts. Yet, model accuracy and utility may be compromised by small study areas and limited integration of species ecology or temporal variability. Here we modelled seasonal habitat suitability for wild pigs, a widespread and harmful invader, in northern Australia. We developed a resource-based, spatially-explicit and regional-scale approach using Bayesian networks and spatial pattern suitability analysis. We integrated important ecological factors such as variability in environmental conditions, breeding requirements and home range movements. The habitat model was parameterized during a structured, iterative expert elicitation process and applied to a wet season and a dry season scenario. Model performance and uncertainty was evaluated against independent distributional data sets. Validation results showed that an expert-averaged model accurately predicted empirical wild pig presences in northern Australia for both seasonal scenarios. Model uncertainty was largely associated with different expert assumptions about wild pigs' resource-seeking home range movements. Habitat suitability varied considerably between seasons, retracting to resource-abundant rainforest, wetland and agricultural refuge areas during the dry season and expanding widely into surrounding grassland floodplains, savanna woodlands and coastal shrubs during the wet season. Overall, our model suggested that suitable wild pig habitat is less widely available in northern Australia than previously thought. Mapped results may be used to quantify impacts, assess risks, justify management investments and target control activities. Our methods are applicable to other wide-ranging species, especially in data-poor situations.

    High Precision Sunphotometer using Wide Dynamic Range (WDR) Camera TrackingThe NASA Ames Sun-photometer-Satellite Group, DOE, PNNL Atmospheric Sciences and Global Change Division, and NASA Goddard's AERONET (AErosol RObotic NETwork) team recently collaborated on the development of a new airborne sunphotometry instrument that provides information on gases and aerosols extending far beyond what can be derived from discrete-channel direct-beam measurements, while preserving or enhancing many of the desirable AATS features (e.g., compactness, versatility, automation, reliability). The enhanced instrument combines the sun-tracking ability of the current 14-Channel NASA Ames AATS-14 with the sky-scanning ability of the ground-based AERONET Sun/sky photometers, while extending both AATS-14 and AERONET capabilities by providing full spectral information from the UV (350 nm) to the SWIR (1,700 nm). Strengths of this measurement approach include many more wavelengths (isolated from gas absorption features) that may be used to characterize aerosols and detailed (oversampled) measurements of the absorption features of specific gas constituents. The Sky Scanning Sun Tracking Airborne Radiometer (3STAR) replicates the radiometer functionality of the AATS-14 instrument but incorporates modern COTS technologies for all instruments subsystems. A 19-channel radiometer bundle design is borrowed from a commercial water column radiance instrument manufactured by Biospherical Instruments of San Diego California (ref, Morrow and Hooker)) and developed using NASA funds under the Small Business Innovative Research (SBIR) program. The 3STAR design also incorporates the latest in robotic motor technology embodied in Rotary actuators from Oriental motor Corp. having better than 15 arc seconds of positioning accuracy. Control system was designed, tested and simulated using a Hybrid-Dynamical modeling methodology. The design also replaces the classic quadrant detector tracking sensor with a

    Button, C; Croft, J L

    2017-12-01

    In the lead article of this special issue, Paul Glazier proposes that Newell's constraints model has the potential to contribute to a grand unified theory of sports performance in that it can help to integrate the disciplinary silos that have typically operated in isolation in sports and exercise science. With a few caveats discussed in this commentary, we agree with Glazier's proposal. However, his ideas suggest that there is a need to demonstrate explicitly how such an integration might occur within applied scientific research. To help fill this perceived 'gap' and thereby illustrate the value of adopting a constraints-led approach, we offer an example of our own interdisciplinary research programme. We believe our research on water safety is ideally suited to this task due to the diverse range of interacting constraints present and as such provides a tangible example of how this approach can unify different disciplinary perspectives examining an important aspect of sport performance.

    The development of facilities for the testing of wide range angle of attack aircraft in the wind tunnel at subsonic regime has done and implemented. Development required to meet the test at an angle of attack from -20 ° to 40 °. Testing the wide range angle of attack aircraft with a wide variation of the angle of attack become important needs. This can be done simply by using the sting support-equipped by internal balance to measure the forces and moments component aerodynamics. The results of development and use on the wide range angle of attack aircraft testing are aerodynamics characteristics in the form of the coefficient three components forces and the three components of the moment. A series of test aircraft was successfully carried out and the results are shown in the form of graphs of characteristic of aerodynamics at wind speed 70 m/s.

    Full Text Available Abstract The complex relationship between globalization and health calls for research from many disciplinary and methodological perspectives. This editorial gives an overview of the content trajectory of the interdisciplinary journal ‘Globalization and Health’ over the first six years of production, 2005 to 2010. The findings show that bio-medical and population health perspectives have been dominant but that social science perspectives have become more evident in recent years. The types of paper published have also changed, with a growing proportion of empirical studies. A special issue on ‘Health systems, health economies and globalization: social science perspectives’ is introduced, a collection of contributions written from the vantage points of economics, political science, psychology, sociology, business studies, social policy and research policy. The papers concern a range of issues pertaining to the globalization of healthcare markets and governance and regulation issues. They highlight the important contribution that can be made by the social sciences to this field, and also the practical and methodological challenges implicit in the study of globalization and health.

  7. Automatic Generation of Wide Dynamic Range Image without Pseudo-Edge Using Integration of Multi-Steps Exposure Images

    Science.gov (United States)

    Migiyama, Go; Sugimura, Atsuhiko; Osa, Atsushi; Miike, Hidetoshi

    Recently, digital cameras are offering technical advantages rapidly. However, the shot image is different from the sight image generated when that scenery is seen with the naked eye. There are blown-out highlights and crushed blacks in the image that photographed the scenery of wide dynamic range. The problems are hardly generated in the sight image. These are contributory cause of difference between the shot image and the sight image. Blown-out highlights and crushed blacks are caused by the difference of dynamic range between the image sensor installed in a digital camera such as CCD and CMOS and the human visual system. Dynamic range of the shot image is narrower than dynamic range of the sight image. In order to solve the problem, we propose an automatic method to decide an effective exposure range in superposition of edges. We integrate multi-step exposure images using the method. In addition, we try to erase pseudo-edges using the process to blend exposure values. Afterwards, we get a pseudo wide dynamic range image automatically.

  8. Thermotaxis of human sperm cells in extraordinarily shallow temperature gradients over a wide range.

    Directory of Open Access Journals (Sweden)

    Anat Bahat

    Full Text Available On the basis of the finding that capacitated (ready to fertilize rabbit and human spermatozoa swim towards warmer temperatures by directing their movement along a temperature gradient, sperm thermotaxis has been proposed to be one of the processes guiding these spermatozoa to the fertilization site. Although the molecular mechanism underlying sperm thermotaxis is gradually being revealed, basic questions related to this process are still open. Here, employing human spermatozoa, we addressed the questions of how wide the temperature range of thermotaxis is, whether this range includes an optimal temperature or whether spermatozoa generally prefer swimming towards warmer temperatures, whether or not they can sense and respond to descending temperature gradients, and what the minimal temperature gradient is to which they can thermotactically respond. We found that human spermatozoa can respond thermotactically within a wide temperature range (at least 29-41°C, that within this range they preferentially accumulate in warmer temperatures rather than at a single specific, preferred temperature, that they can respond to both ascending and descending temperature gradients, and that they can sense and thermotactically respond to temperature gradients as low as <0.014°C/mm. This temperature gradient is astonishingly low because it means that as a spermatozoon swims through its entire body length (46 µm it can sense and respond to a temperature difference of <0.0006°C. The significance of this surprisingly high temperature sensitivity is discussed.

  9. Comprehensive Measurement of Atmospheric Aerosols with a Wide Range Aerosol Spectrometer

    International Nuclear Information System (INIS)

    Keck, L; Pesch, M; Grimm, H

    2011-01-01

    A wide range aerosol spectrometer (WRAS) was used for comprehensive long term measurements of aerosol size distributions. The system combines the results of an optical aerosol spectrometer with the results of a Scanning Mobility Particle Sizer (SMPS) to record essentially the full size range (5 nm - 32 μm) of atmospheric particles in 72 channels. Measurements were carried out over one year (2009) at the Global Atmospheric Watch (GAW)-Station Hohenpeissenberg, Bavaria. Total particle number concentrations obtained from the aerosol size distributions were compared to the total number concentrations measured by a Condensation Particle Counter (CPC). The comparison showed an excellent agreement of the data. The high time resolution of 5 minutes allows the combination of the measured size distributions with meteorological data and correlations to gaseous pollutants (CO, NOx and SO2). A good correlation of particle number and CO concentrations was found for long distance transported small particles, which were probably mainly soot particles. Correlations to NOx were observed for aerosols from local sources such as traffic emissions. The formation of secondary aerosols from gaseous precursors was also observed. Episodes of relatively high concentration of particles in the range of 2-3 μm were probably caused by pollen.

Demonstrated improved performance at low temperature and good cycle life at 40 C with methyl propionate-based electrolyte containing increasing FEC content and the use of LiBOB as an additive. Utilized three-electrode cells to investigate the electrochemical characteristics of high voltage systems coupled with wide operating temperature range electrolytes: From Tafel polarization measurements on each electrode, it is evident the NMC-based cathode displays poor lithium kinetics (being the limiting electrode). The MB-based formulations containing LiBOB delivered the best rate capability at low temperature, which is attributed to improved cathode kinetics. Whereas, the use of lithium oxalate as an additive lead to the highest reversible capacity and lower irreversible losses.

    In this paper a didactical model is presented. The goal of the model is to work as a didactical tool, or conceptual frame, for developing, carrying through and evaluating interdisciplinary activities involving the subject of mathematics and philosophy in the high schools. Through the terms...... of Horizontal Intertwining, Vertical Structuring and Horizontal Propagation the model consists of three phases, each considering different aspects of the nature of interdisciplinary activities. The theoretical modelling is inspired by work which focuses on the students abilities to concept formation in expanded...... domains (Michelsen, 2001, 2005a, 2005b). Furthermore the theoretical description rest on a series of qualitative interviews with teachers from the Danish high school (grades 9-11) conducted recently. The special case of concrete interdisciplinary activities between mathematics and philosophy is also...

  16. The French 35-hour workweek: a wide-ranging social change.

    Science.gov (United States)

    Prunier-Poulmaire, S; Gadbois, C

    2001-12-01

    The reduction of the legal working week to 35 hours in France has generated wide-ranging social change. We examine the resulting changes in working-time patterns as well as their repercussions on the use of the time gained and on the quality of life and health. To compensate the reduction in the length of the working week, companies have modified the working-time patterns, by extending operation time (shiftwork, atypical schedules) and by matching the on-site workforce to production requirements (flexible working hours). They have sought to make more efficient use of working time: job intensification or job compression. The effects on the off-the-job life and health are linked to the shiftwork and atypical schedules designed to increase the company's operating time, and adjustments to the company's need for flexibilization impose working time/free time patterns that are at odds with biological rhythms and social life patterns. Changes to working-time patterns have unexpected consequences for work organization: heightened difficulties for the individual and the crew. These changes may generate a range of health problems related to overwork and stress. The way some companies have adapted may call into question the usefulness of work done by employees, thus damaging their social identity and mental well-being.

  18. Rapid landscape change in 6th century northern Jordan: interdisciplinary geoarchaeological perspectives

    Science.gov (United States)

    Lucke, Bernhard

    2016-04-01

    Landscapes of the ancient fertile crescent are considered affected by soil degradation as result of long-term farming since the Neolithic, and impressive ruins of antiquity led to assumptions that their abandonment must have been conntected with reduced agricultural productivity. In this context, a valley fill near the site of Abila of the Decapolis in northern Jordan was apparently deposited largely during the 6th century AD, and provides evidence for a rapid and intense landscape change during the Late Byzantine period. However, an interdisciplinary case study of land use, soil development, and sediments found that the valley fill cannot be connected with large-scale soil erosion in the vicinity of the site. On the one hand, this is indicated by the distribution of soil development and archaeological material as marker of past land use activity in the past, which suggests that the best soils were and still are used intensively. On the other hand, the sediments seem to point to the occurrence of climatic extremes such as heavy floods, the occurrence of soil creep after water saturation, but also a significant shift to aridity which may have triggered socio-economic changes of subsistence strategies from agriculture to pastoralism. The dates of sediments which are available so far indicate that the climatic change seemingly occurred rapidly within approximately 100 years during the late 6th and early 7th century AD, possibly connected with the "year without sun" or 'Mystery Veil' which the Byzantine historian Procopius described in the year 536 AD. Modern analogies of the Pinatubo eruption in 1991 let it seem possible that a volcanic event, perhaps the outbreak of the Ilopango volcano, was connected with these environmental turbulences. Such events cannot be understood by isolated studies: without a broad interdisciplinary framework, single archives are prone to misinterpretation, and our understanding of the environmental history of Abila is still very limited.

    In this work, we present an electronic apparatus that facilitates the monitoring and analysis of electromagnetic radiation in a very wide frequency range. The device is a combination of real and virtual instruments, taking advantage of new hardware and software; the measurable range of frequencies depends on the speed of an analog/digital converter, reaching tens of Megahertz. The device has been successfully used to monitor the environmental electromagnetic radiation at very low frequency, a very useful parameter in the research of electromagnetic precursors of earthquakes. The apparatus is a new configuration and has advantages with respect to those previously used: when the attached computer is fast, Fourier analysis can be done in real time, can display simultaneously several bands, the digitized data allow a variety of methods of analysis, and the apparatus is very cheap.

    2007-01-01

    GafChromic films have been used at SPring-8 to detect the intensively irradiated parts and protect them from damage by being covered with shield or moved. To extend the usable dose range more widely, a new type of sensitive film EBT was investigated for the introduction. Calibration curves were obtained irradiated with 60Co γ rays and compared with those of other GafChromic films. For the application, these films were set in the white x-ray hutch and the dose distribution was measured. Ratio of doses given by EBT and XT-R indicated the degree of the photon spectrum hardness, which depended on the positions. As a result, dose range from 50 mGy to 300 kGy became available for dose distribution measurements, and a set of films having different energy responses was found to give information of photon spectra

    Turbidity measurement is important for water quality assessment, food safety, medicine, ocean monitoring, etc. In this paper, a method that accurately estimates the turbidity over a wide range is proposed, where the turbidity of the sample is represented as a weighted ratio of the scattered light intensities at a series of angles. An improvement in the accuracy is achieved by expanding the structure of the ratio function, thus adding more flexibility to the turbidity-intensity fitting. Experiments have been carried out with an 850 nm laser and a power meter fixed on a turntable to measure the light intensity at different angles. The results show that the relative estimation error of the proposed method is 0.58% on average for a four-angle intensity combination for all test samples with a turbidity ranging from 160 NTU to 4000 NTU.

  3. Viability of long range dragonfly migration across the Indian Ocean: An energetics perspective

    2016-11-01

    Recently Pantala flavescens (dragonflies) have been reported to migrate in millions from India to Eastern Africa on a multigenerational migratory circuit of length 14000-18000 kms. We attempt to understand the ability of dragonflies to perform long range migration by examining the energetics using computer simulations. In absence of a theory for long range insect migrations, we resort to the extensive literature on long range bird migration from the energetics perspective. The flight energetics depends upon instantaneous power and velocity. The mechanical flight power is computed from the power curve which is then converted to mass depletion using Brequet's equation. However, the mechanical flight power itself depends upon the instantaneous velocity which can vary depending upon the current mass. In order to predict the range in our simulations, we assume that the insect progressively tries to achieve the maximum range velocity. The results indicate that the migration range is approximately 1260 kms in 70 hours based on the true airspeed. However, our analysis is restricted by the lack of data and certain caveats in drag prediction and basal metabolism rate.

  4. Quantum conductance of carbon nanotubes in a wide energy range

    2015-01-01

    The differential conductance of armchair and zigzag carbon nanotubes (CNTs) in a wide energy range has been numerically calculated by using the tight-binding model and the Green’s function method. The effects of the contact coupling between CNTs and electrodes on conductance have been explored. The ballistic conductance is proportional to the band numbers and has a ladder-like feature. As the increase of the contact coupling, the conductance oscillations appear and they are robust against the coupling. More importantly, on the first step of the conductance ladder, the armchair CNTs have two quasi-periodic conductance oscillations, i.e. a rapid conductance oscillation superimposed on a slow fluctuation background; while the zigzag CNTs have only one conductance oscillation. But on the second conductance step, all CNTs have two quasi-periodic conductance oscillations. The physical origin of the conductance oscillations has been revealed

    A new inventive radiation dose monitor, designated as DARWIN (Dose monitoring system Applicable to various Radiations with WIde energy raNges), has been developed for monitoring doses in workspaces and surrounding environments of high energy accelerator facilities. DARWIN is composed of a phoswitch-type scintillation detector, which consists of liquid organic scintillator BC501A coupled with ZnS(Ag) scintillation sheets doped with 6 Li, and a data acquisition system based on a Digital-Storage-Oscilloscope. Scintillations from the detector induced by thermal and fast neutrons, photons and muons were discriminated by analyzing their waveforms, and their light outputs were directly converted into the corresponding doses by applying the G-function method. Characteristics of DARWIN were studied by both calculation and experiment. The calculated results indicate that DARWIN gives reasonable estimations of doses in most radiation fields. It was found from the experiment that DARWIN has an excellent property of measuring doses from all particles that significantly contribute to the doses in surrounding environments of accelerator facilities - neutron, photon and muon with wide energy ranges. The experimental results also suggested that DARWIN enables us to monitor small fluctuation of neutron dose rates near the background-level owing to its high sensitivity. (author)

    Oxides represent the largest family of wide bandgap (WBG) semiconductors and also offer a huge potential range of complementary magnetic and electronic properties, such as ferromagnetism, ferroelectricity, antiferroelectricity and high-temperature superconductivity. Here, we review our integration of WBG and ultra WBG semiconductor oxides into different solar cells architectures where they have the role of transparent conductive electrodes and/or barriers bringing unique functionalities into the structure such above bandgap voltages or switchable interfaces. We also give an overview of the state-of-the-art and perspectives for the emerging semiconductor β- Ga2O3, which is widely forecast to herald the next generation of power electronic converters because of the combination of an UWBG with the capacity to conduct electricity. This opens unprecedented possibilities for the monolithic integration in solar cells of both self-powered logic and power electronics functionalities. Therefore, WBG and UWBG oxides have enormous promise to become key enabling technologies for the zero emissions smart integration of the internet of things.

    Interdisciplinary team working is of paramount importance in the reform of primary care in order to provide cost-effective and comprehensive care. However, international research shows that it is not routine practice in many healthcare jurisdictions. It is imperative to understand levers and barriers to the implementation process. This review examines interdisciplinary team working in practice, in primary care, from the perspective of service providers and analyses 1 barriers and facilitators to implementation of interdisciplinary teams in primary care and 2 the main research gaps. An integrative review following the PRISMA guidelines was conducted. Following a search of 10 international databases, 8,827 titles were screened for relevance and 49 met the criteria. Quality of evidence was appraised using predetermined criteria. Data were analysed following the principles of framework analysis using Normalisation Process Theory (NPT), which has four constructs: sense making, enrolment, enactment, and appraisal. The literature is dominated by a focus on interdisciplinary working between physicians and nurses. There is a dearth of evidence about all NPT constructs apart from enactment. Physicians play a key role in encouraging the enrolment of others in primary care team working and in enabling effective divisions of labour in the team. The experience of interdisciplinary working emerged as a lever for its implementation, particularly where communication and respect were strong between professionals. A key lever for interdisciplinary team working in primary care is to get professionals working together and to learn from each other in practice. However, the evidence base is limited as it does not reflect the experiences of all primary care professionals and it is primarily about the enactment of team working. We need to know much more about the experiences of the full network of primary care professionals regarding all aspects of implementation work. International

    Careful selection and testing of plasma reduces the risk of blood-borne viruses in the starting material for plasma-derived products. Furthermore, effective measures such as pasteurization at 60°C for 10 hours have been implemented in the manufacturing process of therapeutic plasma proteins such as human albumin, coagulation factors, immunoglobulins, and enzyme inhibitors to inactivate blood-borne viruses of concern. A comprehensive compilation of the virus reduction capacity of pasteurization is presented including the effect of stabilizers used to protect the therapeutic protein from modifications during heat treatment. The virus inactivation kinetics of pasteurization for a broad range of viruses were evaluated in the relevant intermediates from more than 15 different plasma manufacturing processes. Studies were carried out under the routine manufacturing target variables, such as temperature and product-specific stabilizer composition. Additional studies were also performed under robustness conditions, that is, outside production specifications. The data demonstrate that pasteurization inactivates a wide range of enveloped and nonenveloped viruses of diverse physicochemical characteristics. After a maximum of 6 hours' incubation, no residual infectivity could be detected for the majority of enveloped viruses. Effective inactivation of a range of nonenveloped viruses, with the exception of nonhuman parvoviruses, was documented. Pasteurization is a very robust and reliable virus inactivation method with a broad effectiveness against known blood-borne pathogens and emerging or potentially emerging viruses. Pasteurization has proven itself to be a highly effective step, in combination with other complementary safety measures, toward assuring the virus safety of final product. © 2017 The Authors Transfusion published by Wiley Periodicals, Inc. on behalf of AABB.

    The paper discusses a multiscale simulation approach for the construction of grain structure of metals and alloys, providing high tensile strength with ductility. This work compares the mechanical behavior of light alloys and the influence of the grain size distribution in a wide range of strain rates. The influence of the grain size distribution on the inelastic deformation and fracture of aluminium and magnesium alloys is investigated by computer simulations in a wide range of strain rates. It is shown that the yield stress depends on the logarithm of the normalized strain rate for light alloys with a bimodal grain distribution and coarse-grained structure.

    The New York and New Jersey Education and Research Center (ERC) provides a range of graduate continuing education for occupational safety and health (OSH) professionals in training. A key element of the education is to provide interdisciplinary training to industrial hygienists, ergonomists, occupational medicine physicians and other health and safety trainees to prepare them for the collaboration required to solve the complex occupational health and safety problems they will face in their careers. This center has developed an innovative interdisciplinary training approach that provides an historical aspect, while allowing the graduate students to identify solutions to occupational issues from a multi-disciplinary approach. The ERC developed a tour that brings students to sites of historical and/or contemporary significance in the occupational safety and health and environmental fields. The ERC has conducted five tours, and has included 85 students and residents as participants. 80% of participants rated the tour as providing a high amount of OSH knowledge gained. 98% of the participants felt the goal of providing interdisciplinary education was achieved. This tour has been successful in bridging the OSH fields to better understand how occupational and environmental exposures have occurred, in order to prevent future exposures so that workplace conditions and health can be improved.

    2014-01-01

    The diffusion of monovacancies in tungsten is studied computationally over a wide temperature range from 1300 K until the melting point of the material. Our modelling is based on Molecular Dynamics technique and Density Functional Theory. The monovacancy migration barriers are calculated using nudged elastic band method for nearest and next-nearest neighbour monovacancy jumps. The diffusion pre-exponential factor for monovacancy diffusion is found to be two to three orders of magnitude higher than commonly used in computational studies, resulting in attempt frequency of the order 10 15 Hz. Multiple nearest neighbour jumps of monovacancy are found to play an important role in the contribution to the total diffusion coefficient, especially at temperatures above 2/3 of T m , resulting in an upward curvature of the Arrhenius diagram. The probabilities for different nearest neighbour jumps for monovacancy in W are calculated at different temperatures

    1992-01-01

    Geriatric health care requires the services of an interdisciplinary health care team to assess, treat and order the social service needs of the older person, and this concept needs to be included in geriatric social work education. But while the necessity of interdisciplinary team care is recognized, little focus has been placed on the actual process of developing a functional team. The issues that arise-disparate terminologies, organizational and administrative differentials, turf-and the steps needed for a team to become viable are described, using an interdisciplinary team based in academia as a case model. The academic interdisciplinary team may easily become a forum for 'hot air' rather than a catalyst for good practice. This danger is reviewed with reference to stages in the interdisciplinary team development-- goal development group affiliation; team awareness; and goal evaluation. The chapter concludes with a discussion on the impact of the interdisciplinary team on faculty, students and the academic setting.

    Light yield nonproportionality and the intrinsic resolution of some low atomic number scintillators were studied by means of the Wide Angle Compton Coincidence (WACC) technique. The plastic and liquid scintillator response to Compton electrons was measured in the energy range of 10 keV up to 4 MeV, whereas a CaF 2 :Eu sample was scanned from 3 keV up to 1 MeV. The nonproportionality of the CaF 2 :Eu light yield has characteristics typical for inorganic scintillators of the multivalent halides group, whereas tested organic scintillators show steeply increasing nonproportionality without saturation point. This is in contrast to the behavior of all known inorganic scintillators having their nonproportionality curves at saturation above energies between tens and several hundred keV.

    Tapping mode atomic force microscopy (AFM), also known as amplitude modulated (AM) or AC mode, is a proven, reliable, and gentle imaging mode with widespread applications. Over the several decades that tapping mode has been in use, quantification of tip-sample mechanical properties such as stiffness has remained elusive. Bimodal tapping mode keeps the advantages of single-frequency tapping mode while extending the technique by driving and measuring an additional resonant mode of the cantilever. The simultaneously measured observables of this additional resonance provide the additional information necessary to extract quantitative nanomechanical information about the tip-sample mechanics. Specifically, driving the higher cantilever resonance in a frequency modulated (FM) mode allows direct measurement of the tip-sample interaction stiffness and, with appropriate modeling, the set point-independent local elastic modulus. Here we discuss the advantages of bimodal tapping, coined AM-FM imaging, for modulus mapping. Results are presented for samples over a wide modulus range, from a compliant gel (∼100 MPa) to stiff materials (∼100 GPa), with the same type of cantilever. We also show high-resolution (subnanometer) stiffness mapping of individual molecules in semicrystalline polymers and of DNA in fluid. Combined with the ability to remain quantitative even at line scan rates of nearly 40 Hz, the results demonstrate the versatility of AM-FM imaging for nanomechanical characterization in a wide range of applications.

    Interdisciplinary team working could facilitate the efficient provision and coordination of increasingly diverse health services, thereby improving the quality of patient care. The purpose of this study was to describe knowledge of interdisciplinary team working among obstetricians and gynecologists in two teaching hospitals in South East Nigeria and to determine their attitude toward an interdisciplinary collaborative approach to patient care in these institutions. This was a questionnaire-based cross-sectional study. Data analysis involved descriptive statistics and was carried out using Statistical Package for the Social Sciences software version 17.0 for Windows. In total, 116 doctors participated in the study. The mean age of the respondents was 31.9±7.0 (range 22-51) years. Approximately 74% of respondents were aware of the concept of interdisciplinary team working. Approximately 15% of respondents who were aware of the concept of interdisciplinary team working had very good knowledge of it; 52% had good knowledge and 33% had poor knowledge. Twenty-nine percent of knowledgeable respondents reported ever receiving formal teaching/training on interdisciplinary team working in the course of their professional development. About 78% of those aware of team working believed that interdisciplinary teams would be useful in obstetrics and gynecology practice in Nigeria, with 89% stating that it would be very useful. Approximately 77% of those aware of team working would support establishment and implementation of interdisciplinary teams at their centers. There was a high degree of knowledge of the concept and a positive attitude toward interdisciplinary team working among obstetricians and gynecologists in the study centers. This suggests that the attitude of physicians may not be an impediment to implementation of a collaborative interdisciplinary approach to clinical care in the study centers.

  1. Wide wavelength range tunable one-dimensional silicon nitride nano-grating guided mode resonance filter based on azimuthal rotation

    Full Text Available We describe wavelength tuning in a one dimensional (1D silicon nitride nano-grating guided mode resonance (GMR structure under conical mounting configuration of the device. When the GMR structure is rotated about the axis perpendicular to the surface of the device (azimuthal rotation for light incident at oblique angles, the conditions for resonance are different than for conventional GMR structures under classical mounting. These resonance conditions enable tuning of the GMR peak position over a wide range of wavelengths. We experimental demonstrate tuning over a range of 375 nm between 500 nm˜875 nm. We present a theoretical model to explain the resonance conditions observed in our experiments and predict the peak positions with show excellent agreement with experiments. Our method for tuning wavelengths is simpler and more efficient than conventional procedures that employ variations in the design parameters of structures or conical mounting of two-dimensional (2D GMR structures and enables a single 1D GMR device to function as a high efficiency wavelength filter over a wide range of wavelengths. We expect tunable filters based on this technique to be applicable in a wide range of fields including astronomy and biomedical imaging.

    The Interdisciplinary Earth Data Alliance (IEDA) is an NSF-funded data facility that provides data tools and services to support the Ocean, Earth, and Polar Sciences. IEDA systems, developed and maintained primarily by the IEDA partners EarthChem and the Marine Geoscience Data System (MGDS), serve as primary community data collections for global geochemistry and marine geoscience research and support the preservation, discovery, retrieval, and analysis of a wide range of observational field and analytical data types. Individual IEDA systems originated independently and differ from one another in purpose and scope. Some IEDA systems are data repositories (EarthChem Library, Marine Geo-Digital Library), while others are actively maintained data syntheses (GMRT, PetDB, EarthChem Portal, Geochron). Still others are data visualization and analysis tools (GeoMapApp). Although the diversity of IEDA's data types, tools, and services is a major strength and of high value to investigators, it can be a source of confusion. And while much of the data managed in IEDA systems is appropriate for interdisciplinary research, investigators may be unfamiliar with the user interfaces and services of each system, especially if it is not in their primary discipline. This presentation will highlight new ways in which IEDA helps researchers to more efficiently navigate data submission and data access. It will also discuss how IEDA promotes discovery and access within and across its systems, to serve interdisciplinary science while also remaining aware of and responsive to the more specific needs of its disciplinary user communities. The IEDA Data Submission Hub (DaSH), which is currently under development, aspires to streamline the submission process for both the science data contributor and for the repository data curator. Instead of users deciding a priori, which system they should contribute their data to, the DaSH helps route them to the appropriate repository based primarily on data

    This paper reports on the initial findings of an interdisciplinary study exploring perceptions of space and place through alternate ways of mapping. The research project aims to bring depth and meaning to places by utilising a combination of diverse influences and responses, including emotional, sensory, memory and imaginary. It investigates mapping from a designer's perspective, with further narration from both the cartographic science and fine art perspectives. It examines the role of design and artistic expression in the cartographic process, and its capacity to effect and transform the appearance, reading and meaning of the final cartographic outcome (Robinson 2010). The crossover between the cartographic sciences and the work of artists who explore space and place enables an interrogation of where these fields collide or alternatively merge, in order to challenge the definition of a map. By exploring cartography through the overlapping of the distinct fields of science and art, this study challenges and questions the tipping point of when a map ceases to be a map and becomes art.

  9. An operating principle of the turtle utricle to detect wide dynamic range.

    Nam, Jong-Hoon

    2018-03-01

    The utricle encodes both static information such as head orientation, and dynamic information such as vibrations. It is not well understood how the utricle can encode both static and dynamic information for a wide dynamic range (from 2 times the gravitational acceleration; from DC to > 1000 Hz vibrations). Using computational models of the hair cells in the turtle utricle, this study presents an explanation on how the turtle utricle encodes stimulations over such a wide dynamic range. Two hair bundles were modeled using the finite element method-one representing the striolar hair cell (Cell S), and the other representing the medial extrastriolar hair cell (Cell E). A mechano-transduction (MET) channel model was incorporated to compute MET current (i MET ) due to hair bundle deflection. A macro-mechanical model of the utricle was used to compute otoconial motions from head accelerations (a Head ). According to known anatomical data, Cell E has a long kinocilium that is embedded into the stiff otoconial layer. Unlike Cell E, the hair bundle of Cell S falls short of the otoconial layer. Considering such difference in the mechanical connectivity between the hair cell bundle and the otoconial layer, three cases were simulated: Cell E displacement-clamped, Cell S viscously-coupled, and Cell S displacement-clamped. Head accelerations at different amplitude levels and different frequencies were simulated for the three cases. When a realistic head motion was simulated, Cell E was responsive to head orientation, while the viscously-coupled Cell S was responsive to fast head motion imitating the feeding strike of a turtle.

  12. Natural selection constrains neutral diversity across a wide range of species.

    The neutral theory of molecular evolution predicts that the amount of neutral polymorphisms within a species will increase proportionally with the census population size (Nc). However, this prediction has not been borne out in practice: while the range of Nc spans many orders of magnitude, levels of genetic diversity within species fall in a comparatively narrow range. Although theoretical arguments have invoked the increased efficacy of natural selection in larger populations to explain this discrepancy, few direct empirical tests of this hypothesis have been conducted. In this work, we provide a direct test of this hypothesis using population genomic data from a wide range of taxonomically diverse species. To do this, we relied on the fact that the impact of natural selection on linked neutral diversity depends on the local recombinational environment. In regions of relatively low recombination, selected variants affect more neutral sites through linkage, and the resulting correlation between recombination and polymorphism allows a quantitative assessment of the magnitude of the impact of selection on linked neutral diversity. By comparing whole genome polymorphism data and genetic maps using a coalescent modeling framework, we estimate the degree to which natural selection reduces linked neutral diversity for 40 species of obligately sexual eukaryotes. We then show that the magnitude of the impact of natural selection is positively correlated with Nc, based on body size and species range as proxies for census population size. These results demonstrate that natural selection removes more variation at linked neutral sites in species with large Nc than those with small Nc and provides direct empirical evidence that natural selection constrains levels of neutral genetic diversity across many species. This implies that natural selection may provide an explanation for this longstanding paradox of population genetics.

    Highlights: • TiNbCN–Ag coatings for wide temperature range tribological applications. • Alloying with Nb and Ag improve tribological properties and oxidation resistance. • Ag-rich TiNbCN coatings show friction coefficient below 0.45 in range of 25–700 °C. • Ag-doped coatings show active oxidation protection and self-healing functionality. - Abstract: Ag- and Nb-doped TiCN coatings with about 2 at.% of Nb and Ag contents varied between 4.0 and 15.1 at.% were designed as promising materials for tribological applications in a wide temperature range. We report on the structure, mechanical, and tribological properties of TiNbCN-Ag coatings fabricated by simultaneous co-sputtering of TiC{sub 0.5} + 10%Nb{sub 2}C and Ag targets in comparison with those of Ag-free coating. The tribological characteristics were evaluated during constant-temperature tests both at room temperature and 300 °C, as well as during dynamic temperature ramp tests in the range of 25–700 °C. The coating structure and elemental composition were studied by means of X-ray diffraction, scanning and transmission electron microscopy, and glow discharge optical emission spectroscopy. The coating microstructures and elemental compositions inside wear tracks, as well as the wear products, were examined by scanning electron microscopy, energy-dispersive spectroscopy, and Raman spectroscopy. We demonstrate that simultaneous alloying with Nb and Ag permits to overcome the main drawbacks of TiCN coatings such as their relatively high values of friction coefficient at elevated temperatures and low oxidation resistance. It is shown that a relatively high amount of Ag (15 at.%) is required to provide enhanced tribological behavior in a wide temperature range of 25–700 °C. In addition, the prepared Ag-doped coatings demonstrated active oxidation protection and self-healing functionality due to the segregation of Ag metallic particles in damage areas such as cracks, pin-holes, or oxidation sites.

    Integrated electronic circuitries with pressure sensors have been extensively researched as a key component for emerging electronics applications such as electronic skins and health-monitoring devices. Although existing pressure sensors display high sensitivities, they can only be used for specific purposes due to the narrow range of detectable pressure (under tens of kPa) and the difficulty of forming highly integrated arrays. However, it is essential to develop tactile pressure sensors with a wide pressure range in order to use them for diverse application areas including medical diagnosis, robotics or automotive electronics. Here we report an unconventional approach for fabricating fully integrated active-matrix arrays of pressure-sensitive graphene transistors with air-dielectric layers simply formed by folding two opposing panels. Furthermore, this realizes a wide tactile pressure sensing range from 250 Pa to ∼3 MPa. Additionally, fabrication of pressure sensor arrays and transparent pressure sensors are demonstrated, suggesting their substantial promise as next-generation electronics.

    1992-01-01

    In this paper, a fuzzy logic controller design for optimal reactor temperature control is presented. Since fuzzy logic controllers rely on an expert's knowledge of the process, they are hard to optimize. An optimal controller is used in this paper as a reference model, and a Kalman filter is used to automatically determine the rules for the fuzzy logic controller. To demonstrate the robustness of this design, a nonlinear six-delayed-neutron-group plant is controlled using a fuzzy logic controller that utilizes estimated reactor temperatures from a one-delayed-neutron-group observer. The fuzzy logic controller displayed good stability and performance robustness characteristics for a wide range of operation

  17. Wide-Range Highly-Efficient Wireless Power Receivers for Implantable Biomedical Sensors

    2016-11-01

    Wireless power transfer (WPT) is the key enabler for a myriad of applications, from low-power RFIDs, and wireless sensors, to wirelessly charged electric vehicles, and even massive power transmission from space solar cells. One of the major challenges in designing implantable biomedical devices is the size and lifetime of the battery. Thus, replacing the battery with a miniaturized wireless power receiver (WPRx) facilitates designing sustainable biomedical implants in smaller volumes for sentient medical applications. In the first part of this dissertation, we propose a miniaturized, fully integrated, wirelessly powered implantable sensor with on-chip antenna, designed and implemented in a standard 0.18μm CMOS process. As a batteryless device, it can be implanted once inside the body with no need for further invasive surgeries to replace batteries. The proposed single-chip solution is designed for intraocular pressure monitoring (IOPM), and can serve as a sustainable platform for implantable devices or IoT nodes. A custom setup is developed to test the chip in a saline solution with electrical properties similar to those of the aqueous humor of the eye. The proposed chip, in this eye-like setup, is wirelessly charged to 1V from a 5W transmitter 3cm away from the chip. In the second part, we propose a self-biased, differential rectifier with enhanced efficiency over an extended range of input power. A prototype is designed for the medical implant communication service (MICS) band at 433MHz. It demonstrates an efficiency improvement of more than 40% in the rectifier power conversion efficiency (PCE) and a dynamic range extension of more than 50% relative to the conventional cross-coupled rectifier. A sensitivity of -15.2dBm input power for 1V output voltage and a peak PCE of 65% are achieved for a 50k load. In the third part, we propose a wide-range, differential RF-to-DC power converter using an adaptive, self-biasing technique. The proposed architecture doubles

    The dosimetric properties of a portable TLD reader are described. The TLD system named 'Pille' or 'moth' consists of a lightweight battery-operated portable TLD reader and its CaSO 4 :Dy bulb dosemeters. The reproducibility of the TLD system at constant temperature was found to be better than + -2%, and the mean time between failures exceeded 5 years. The dose range of the system is wide, covering more than 6 orders of magnitude, from 5 μGy to 10 Gy. The energy dependence of the CaSO 4 :Dy bulb dosemeters is less than + - 20% above 100 keV in the energy compensation capsules. Without additional annealing, the bulb dosemeters can be re-used at least 100 times, which is an important aspect during in situ measurements. (author)

    2013-12-01

    Full Text Available During the past two decades there has been a heightened policy and research interest in the entrepreneur and entrepreneurship in South Africa and other countries. The recent focus on entrepreneurship has made an understanding that the nature or role of entrepreneurs is essential for economic growth and business development. Without entrepreneurs, there cannot be any entrepreneurship, whether in a large or small venture. It is increasingly realized that SMME entrepreneurs and entrepreneurship are critical to the generation of output growth, employment creation, wealth expansion, revenue generation and poverty alleviation for individual and national prosperity, when many large firms are downsizing and retrenching labour, amidst a background of recessionary circumstances and fiscal stress. Entrepreneurship has been conceptualized by different schools of thought, stressing different functions, under diverse circumstances in different historical times. This paper critically examines the nature of entrepreneurship by selectively drawing from the economic, management and psychological schools. It then presents an eclectic view of entrepreneurship related to decision-making ability under conditions of uncertainty by individuals who have access to and can control the utilization of resources in response to opportunities. The paper offers some pointers for enhancing the supply of effective entrepreneurship at the national level in South Africa, and suggests that an interdisciplinary approach is needed to gain a better understanding of entrepreneurship.

  5. The concept of psychical trauma: a bridge in interdisciplinary space.

    Science.gov (United States)

    Tutté, Juan Carlos

    2004-08-01

    The concept of trauma currently occupies a central position in interdisciplinary dialogue. Using the concept of psychical trauma as a bridge, the author attempts an interdisciplinary dialogue with psychiatry, biology and neuroscience. Beginning with the concept of psychical trauma in Freud, the author reviews the evolution of Freud's thinking, and links it with the ideas of Ferenczi and post-Freudian psychoanalytical authors. From a different framework, he considers the present state of research on post-traumatic stress disorder in current psychiatric nosography and attempts an interdisciplinary approximation to the concept of psychical trauma. Interesting ideas like the traumatic situation, trauma spectrum and psychopathological spectrum emerge, which enable a better understanding of the concept of psychical trauma through its relatedness, as a bridge connecting a broad psychopathological range extending from normality to psychosis. The ensuing possible relative loss of nosographical rigour is more than compensated by the resulting increased understanding and enlarged therapeutic possibilities. In the second part of the paper, the author attempts a dialogue with neuroscience, taking into account new advances in current research on emotion and memory, and making them compatible with the psychoanalytical concept of trauma. In this sense, the paper underlines the importance of emotion and crucially of memory, regarded as a fundamental axis of the subject explored in this paper. Here a substantial distinction which is pertinent for analytical work appears: declarative memories versus non-declarative or procedural memories. In a concluding discussion the author argues that, taking into account the implications of these current notions regarding a number of theoretical and technical aspects, psychoanalysis currently holds a privileged position, both in its potential for prevention and regarding the treatment of patients, in so far as, through interdisciplinary dialogue

  6. Neural network for adapting nuclear power plant control for wide-range operation

    International Nuclear Information System (INIS)

    Ku, C.C.; Lee, K.Y.; Edwards, R.M.

    1991-01-01

    A new concept of using neural networks has been evaluated for optimal control of a nuclear reactor. The neural network uses the architecture of a standard backpropagation network; however, a new dynamic learning algorithm has been developed to capture the underlying system dynamics. The learning algorithm is based on parameter estimation for dynamic systems. The approach is demonstrated on an optimal reactor temperature controller by adjusting the feedback gains for wide-range operation. Application of optimal control to a reactor has been considered for improving temperature response using a robust fifth-order reactor power controller. Conventional gain scheduling can be employed to extend the range of good performance to accommodate large changes in power where nonlinear characteristics significantly modify the dynamics of the power plant. Gain scheduling is developed based on expected parameter variations, and it may be advantageous to further adapt feedback gains on-line to better match actual plant performance. A neural network approach is used here to adapt the gains to better accommodate plant uncertainties and thereby achieve improved robustness characteristics

  7. Self-control mediates the relationship between time perspective and BMI.

    Price, Menna; Higgs, Suzanne; Lee, Michelle

    2017-01-01

    Trait future time perspective measures the extent to which behaviour is dominated by a striving for future goals and rewards. Trait present time perspective measures orientation towards immediate pleasure. Previous research has explored the relationship between future and present time perspective and BMI with mixed findings. In addition, the psychological mechanism underlying this relationship is unclear. Self-control is a likely candidate, as it has been related to both BMI and time perspective, but the relationship between all of these concepts has not been examined in a single study. Therefore, the aim of this study was to examine if trait self-control mediates the relationship between time perspective (future and present) and BMI. Self-report time perspective (ZTPI), self-control (SCS) and height/weight data were collected using an online survey from a mixed student and community sample (N = 218) with wide ranging age (mean 29, SD 11, range 18-73 years) and BMI (mean 24, SD 4, range 15-43). The results of a structural equation model including both facets of time perspective suggested that the traits are related yet distinct measures that independently predict BMI through changes in self-control. Bootstrap mediation analysis showed that self-control mediated the relationship between both future time perspective (95% CI, -0.10 to -0.02) and present time perspective (95% CI, 0.03 to 0.17), and BMI in opposite directions. Participants with higher future time perspective scores (higher present time perspective scores) had higher (lower) self-control, which predicted lower (higher) BMI. These results are consistent with previous research suggesting an important role for time perspective in health outcomes. Self-control likely mediates the relationship between temporal perspectives and BMI, suggesting that time perspective may be a target for individualised interventions. Copyright © 2016 Elsevier Ltd.

  8. Healthcare management strategies: interdisciplinary team factors.

    2012-12-01

    Interdisciplinary team factors are significant contributors to clinical performance and associated patient outcomes. Quality of care and patient safety initiatives identify human factors associated with team performance as a prime improvement area for clinical patient care. The majority of references to interdisciplinary teams in obstetrics and gynecology in the literature recommends the use of multidisciplinary approaches when managing complex medical cases. The reviewed literature suggests that interdisciplinary team development is important for achieving optimally efficient and effective performance; however, few reports provide specific recommendations for how to optimally achieve these objectives in the process of providing interdisciplinary care to patients. The absence of these recommendations presents a significant challenge for those tasked with improving team performance in the workplace. The prescribed team development programs cited in the review are principally built around communication strategies and simulation-based training mechanisms. Few reports provide descriptions of optimal team-based competencies in the various contexts of obstetric and gynecology teams. However, team-based evaluation strategies and empirical data documenting the transfer of team training to applied clinical care are increasing in number and quality. Our findings suggest that research toward determining team factors that promote optimal performance in applied clinical practice requires definition of specific competencies for the variable teams serving obstetrics and gynecology.

    Current trends in health care research point to a shift from disciplinary models to interdisciplinary team-based mixed methods inquiry designs. This keynote address discusses the problems and prospects of creating vibrant mixed methods health care interdisciplinary research teams that can harness their potential synergy that holds the promise of addressing complex health care issues. We examine the range of factors and issues these types of research teams need to consider to facilitate efficient interdisciplinary mixed methods team-based research. It is argued that concepts such as disciplinary comfort zones, a lack of attention to team dynamics, and low levels of reflexivity among interdisciplinary team members can inhibit the effectiveness of a research team. This keynote suggests a set of effective strategies to address the issues that emanate from the new field of research inquiry known as team science as well as lessons learned from tapping into research on organizational dynamics. © The Author(s) 2016.

    2006-01-01

    Without formal education, many healthcare professionals fail to develop interdisciplinary team skills; however, when students are socialized to interdisciplinary practice through academic clinical learning experiences, effective collaboration skills can be developed. Increasingly, educational environments are challenged to include clinical experiences for students that teach and model interdisciplinary collaboration. The purpose of this quality improvement initiative was to create an interdisciplinary educational experience for clinical nurse specialist (CNS) students and postgraduate physicians. The interdisciplinary learning experience, supported by an educational grant, provided an interdisciplinary cohort of learners an opportunity to engage in a clinically focused learning experience. The interdisciplinary cohort consisted of CNS students and physicians in various stages of postgraduate training. The clinical experience selected was a quality improvement initiative in which the students were introduced to the concepts and tools of quality improvement. During this 1-month clinical experience, students applied the new skills by implementing a quality improvement project focusing on medication reconciliation in the outpatient setting. The CNS core competencies and outcomes were used to shape the experience for the CNS students. The CNS students exhibited 5 of the 7 essential characteristics of the CNS (leadership, collaboration, consultation skills, ethical conduct, and professional attributes) while demonstrating competencies and fulfilling performance expectations. During this learning experience, the CNS students focused on competencies and outcomes in the organizational sphere of influence. Multiple facilitating factors and barriers were identified. This interdisciplinary clinical experience in a quality improvement initiative provided valuable opportunities for CNS students to develop essential CNS characteristics and to explore practice competencies in the

    Global environmental problems such as climate change are not bounded by national borders or scientific disciplines, and therefore require international, interdisciplinary teamwork to develop understandings of their causes and solutions. Interdisciplinary scientific work is difficult enough, but these challenges are often magnified when teams also work across national boundaries. The literature on the challenges of interdisciplinary research is extensive. However, research on international, interdisciplinary teams is nearly non-existent. Our objective is to fill this gap by reporting on results from a study of a large interdisciplinary, international National Science Foundation Partnerships for International Research and Education (NSF-PIRE) research project across the Americas. We administered a structured questionnaire to team members about challenges they faced while working together across disciplines and outside of their home countries in Argentina, Brazil, and Mexico. Analysis of the responses indicated five major types of barriers to conducting interdisciplinary, international research: integration, language, fieldwork logistics, personnel and relationships, and time commitment. We discuss the causes and recommended solutions to the most common barriers. Our findings can help other interdisciplinary, international research teams anticipate challenges, and develop effective solutions to minimize the negative impacts of these barriers to their research.

    Background Interdisciplinary team working is of paramount importance in the reform of primary care in order to provide cost-effective and comprehensive care. However, international research shows that it is not routine practice in many healthcare jurisdictions. It is imperative to understand levers and barriers to the implementation process. This review examines interdisciplinary team working in practice, in primary care, from the perspective of service providers and analyses 1 barriers and facilitators to implementation of interdisciplinary teams in primary care and 2 the main research gaps. Methods and findings An integrative review following the PRISMA guidelines was conducted. Following a search of 10 international databases, 8,827 titles were screened for relevance and 49 met the criteria. Quality of evidence was appraised using predetermined criteria. Data were analysed following the principles of framework analysis using Normalisation Process Theory (NPT), which has four constructs: sense making, enrolment, enactment, and appraisal. The literature is dominated by a focus on interdisciplinary working between physicians and nurses. There is a dearth of evidence about all NPT constructs apart from enactment. Physicians play a key role in encouraging the enrolment of others in primary care team working and in enabling effective divisions of labour in the team. The experience of interdisciplinary working emerged as a lever for its implementation, particularly where communication and respect were strong between professionals. Conclusion A key lever for interdisciplinary team working in primary care is to get professionals working together and to learn from each other in practice. However, the evidence base is limited as it does not reflect the experiences of all primary care professionals and it is primarily about the enactment of team working. We need to know much more about the experiences of the full network of primary care professionals regarding all aspects

    2017-11-01

    Full Text Available In a series of three articles, presented at the Goshen Annual Conference on Science and Religion in 2015, with the theme ‘Interdisciplinary Theology and the Archeology of Personhood’, J. Wentzel van Huyssteen considers the problem of human evolution – also referred to as ‘the archaeology of personhood’ – and its broader impact on theological anthropology. This trajectory of lectures tracks a select number of challenging contemporary proposals for the evolution of crucially important aspects of human personhood. These are aspects that were all of great significance for Darwin: the evolution of cognition, the evolution of imagination, music and language, the evolution of morality, and the evolution of the religious disposition.

    Most bacteria known to be electrochemically active have been harvested in the anodic compartments of microbial fuel cells (MFCs) and are able to use electrodes as electron acceptors. The reverse phenomenon, i.e. using solid electrodes as electron donors, is not so widely studied. To our knowledge, most of the electrochemically active bacteria are Gram-negative. The present study implements a transitory electrochemical technique (cyclic voltammetry) to study the microbial catalysis of the electrochemical reduction of oxygen. It is demonstrated that a wide range of aerobic and facultative anaerobic bacteria are able to catalyze oxygen reduction. Among these electroactive bacteria, several were Gram-positive. The transfer of electrons was direct since no activity was obtained with the filtrate. These findings, showing a widespread property among bacteria including Gram-positive ones, open new and interesting routes in the field of electroactive bacteria research. (author)

  19. Interdisciplinary Management of Cystic Neoplasms of the Pancreas

    Directory of Open Access Journals (Sweden)

    Linda S. Lee

    2012-01-01

    Full Text Available Cystic neoplasms of the pancreas are increasingly recognized due to the frequent use of abdominal imaging. It is reported that up to 20% of abdominal cross-sectional scans identify incidental asymptomatic pancreatic cysts. Proper characterization of pancreatic cystic neoplasms is important not only to recognize premalignant lesions that will require surgical resection, but also to allow nonoperative management of many cystic lesions that will not require resection with its inherent morbidity. Though reliable biomarkers are lacking, a wide spectrum of diagnostic modalities are available to evaluate pancreatic cystic neoplasms, including radiologic, endoscopic, laboratory, and pathologic analysis. An interdisciplinary approach to management of these lesions which incorporates recent, specialty-specific advances in the medical literature is herein suggested.

    Since society and science need interdisciplinary works, the interesting topic of chaos is chosen for interdisciplinary education in physics. The educational programme contains various university-level activities such as computer simulations, chaos experiment and team projects besides ordinary teaching. According to the participants, the programme seems useful and good. In addition, we discuss some issues which can be important to interdisciplinary education in physics: for example the possible difficulties in programme design, the expertise barriers of non-major fields, the role of non-theoretical education in understanding and the project-type team activities

  2. The influence of interdisciplinary collaboration on decision making: a framework to analyse stakeholder coalitions, evolution and learning in strategic delta planning

    2015-04-01

    The sustained development of urbanizing deltas requires that conflicting interests are reconciled, in an environment characterized by technical complexity and knowledge limitations. However, integrating ideas and establishing cooperation between actors with different backgrounds and roles still proves a challenge. Agreeing on strategic choices is difficult and implementation of agreed plans may lead to unanticipated and unintended outcomes. How can individual disciplinary perspectives come together and establish a broadly-supported and well-informed plan, the implementation of which contributes to sustainable delta development? The growing recognition of this need to bring together different stakeholders and different disciplinary perspectives runs parallel to a paradigm shift from 'hard' hydrological engineering to multi-functional and more 'soft' hydrological engineering in water management. As a result, there is now more attention for interdisciplinary collaboration that not only takes the physical characteristics of water systems into account, but also the interaction between physical and societal components of these systems. Thus, it is important to study interdisciplinary collaboration and how this influences decision-making. Our research looks into this connection, using a case in delta planning in the Netherlands, where there have been several (attempts for) integration of spatial planning and flood risk/ water management, e.g. in the case of the Dutch Delta Programme. This means that spatial designers and their designs play an important role in the strategic delta planning process as well, next to civil engineers, etc. This study explores the roles of stakeholders, experts and policy makers in interdisciplinary decision-making in dynamic delta planning processes, using theories and methods that focus on coalitions, learning and changes over time in policy and planning processes. This requires an expansion of the existing frameworks to study

    Interdisciplinary cognitive rehabilitation is emerging as the expected standard of care for individuals with mild to moderate degrees of cognitive impairment for a variety of etiologies. There is a growing body of evidence in cognitive rehabilitation literature supporting the involvement of multiple disciplines, with the use of cognitive support technologies (CSTs), in delivering cognitive therapy to individuals who require cognitive rehabilitative therapies. This article provides an overview of the guiding theories related to traditional approaches of cognitive rehabilitation and the positive impact of current theoretical models of an interdisciplinary approach in clinical service delivery of this rehabilitation. A theoretical model of the Integrative Cognitive Rehabilitation Program (ICRP) will be described in detail along with the practical substrates of delivering specific interventions to individuals and caregivers who are living with mild to moderate cognitive impairment. The ultimate goal of this article is to provide a clinically useful resource for direct service providers. It will serve to further clinical knowledge and understanding of the evolution from traditional silo based treatment paradigms to the current implementation of multiple perspectives and disciplines in the pursuit of patient centered care. The article will discuss the theories that contributed to the development of the interdisciplinary team and the ICRP model, implemented with individuals with mild to moderate cognitive deficits, regardless of etiology. The development and implementation of specific assessment and intervention strategies in this cognitive rehabilitation program will also be discussed. The assessment and intervention strategies utilized as part of ICRP are applicable to multiple clinical settings in which individuals with cognitive impairment are served. This article has specific implications for rehabilitation which include: (a) An Interdisciplinary Approach is an

    Given the call for more interdisciplinary research in public health, the objectives of this study were to (1) examine the correlates of interdisciplinary dissertation completion and (2) identify secondary fields most common among interdisciplinary public health graduates. We analyzed pooled cross-sectional data from 11 120 doctoral graduates in the Survey of Earned Doctorates, 2003-2015. The primary outcome was interdisciplinary dissertation completion. Covariates included primary public health field, sociodemographic characteristics, and institutional attributes. From 2003 to 2015, a total of 4005 of 11 120 (36.0%) doctoral graduates in public health reported interdisciplinary dissertations, with significant increases observed in recent years. Compared with general public health graduates, graduates of environmental health (odds ratio [OR] = 1.74; P dissertation work, whereas graduates from biostatistics (OR = 0.51; P dissertation was associated with being male, a non-US citizen, a graduate of a private institution, and a graduate of an institution with high but not the highest level of research activity. Many secondary dissertation fields reported by interdisciplinary graduates included other public health fields. Although interdisciplinary dissertation research among doctoral graduates in public health has increased in recent years, such work is bounded in certain fields of public health and certain types of graduates and institutions. Academic administrators and other stakeholders may use these results to inform greater interdisciplinary activity during doctoral training and to evaluate current and future collaborations across departments or schools.

  10. Interdisciplinary Knowledge Integration: Genuine Scientific Inquiry or 'Full-Bodied' Red Wine?

    Christakos, G.

    2004-12-01

    If the development of conceptual models is going to produce rigorous rules for the integration of knowledge from different disciplines and levels of organization, it should rely on an adequate understanding of scientific interdisciplinarity. Interdisciplinarity, however, is not always a clearly understood and widely accepted concept: (i) Interdisciplinarity has been viewed by certain groups in the same context as the unification of science, which refers to the pyramidal hierarchy that reduces one domain of science to another, seeking the unity of science and searching for the ultimate scientific truth. (ii) A distinction is made between interdisciplinarity producing a new discipline and interdisciplinarity involving the continuing interaction of a variety of disciplines without leading to a separate discipline. (iii) Another distinction is made between interdisciplinarity viewed as a merely practical activity happening on an everyday basis (e.g., studying the components of structured whole in isolation and applying ad hoc combinations to yield the final result) and interdisciplinarity considered for scientific research purposes (in which case issues of disciplinary incompleteness and non-reductive autonomy to be blended with another one may arise). In view of the above, genuinely interdisciplinary and innovative knowledge integration should not be confused with cosmetic inderdisciplinarity, the latter having a superficial and ad hoc interdisciplinary character allowing disciplinary business to go on as usual at the cheap price of some interdisciplinary rhetoric. In the cosmetic case 'interdisciplinarity' is used to describe -and praise- research projects as routinely as 'full-bodied' is used to describe red wines.

    In this paper, inspired by the plenary panel at the 2013 meeting of the International Society for Traumatic Stress Studies, Dr. Steven Southwick (chair) and multidisciplinary panelists Drs. George Bonanno, Ann Masten, Catherine Panter-Brick, and Rachel Yehuda tackle some of the most pressing current questions in the field of resilience research including: (1) how do we define resilience, (2) what are the most important determinants of resilience, (3) how are new technologies informing the science of resilience, and (4) what are the most effective ways to enhance resilience? These multidisciplinary experts provide insight into these difficult questions, and although each of the panelists had a slightly different definition of resilience, most of the proposed definitions included a concept of healthy, adaptive, or integrated positive functioning over the passage of time in the aftermath of adversity. The panelists agreed that resilience is a complex construct and it may be defined differently in the context of individuals, families, organizations, societies, and cultures. With regard to the determinants of resilience, there was a consensus that the empirical study of this construct needs to be approached from a multiple level of analysis perspective that includes genetic, epigenetic, developmental, demographic, cultural, economic, and social variables. The empirical study of determinates of resilience will inform efforts made at fostering resilience, with the recognition that resilience may be enhanced on numerous levels (e.g., individual, family, community, culture).

    2006-01-01

    The performance in terms of efficiency of the existing power supplies used for PFC is very dependent on the input voltage range. The boost converter is the most commonly used PFC converter because of its simplicity and high efficiency. But, the boost converter as well as other known converters...... suffers a major penalty in efficiency when used at the low end of the voltage range (90VAC) in a universal voltage range application (90-270VAC). This paper addresses this problem by suggesting a new family of converters that effectively reduces the apparent voltage range with a factor of 2 by changing...... the converter topology according to the input voltage. This new converter type has been named: efficient wide range converter (EWiRaC). The performance of the EWiRaC is experimental verified in a universal input range (90-270VAC) application with an output voltage of 185VDC capable of 500W output power. The EWi...

    2009-01-01

    Based on the theory of irreversible thermodynamics, the present work proposes a dislocation-based model to describe the plastic deformation of FCC metals over wide ranges of strain rates. The stress-strain behaviour and the evolution of the average dislocation density are derived. It is found that there is a transitional strain rate (∼ 10 4 s -1 ) over which the phonon drag effects appear, resulting in a significant increase in the flow stress and the average dislocation density. The model is applied to pure Cu deformed at room temperature and at strain rates ranging from 10 -5 to 10 6 s -1 showing good agreement with experimental results.

    The wide angular-range chopper spectrometer ARCS at the Spallation Neutron Source (SNS) is optimized to provide a high neutron flux at the sample position with a large solid angle of detector coverage. The instrument incorporates modern neutron instrumentation, such as an elliptically focused neutron guide, high speed magnetic bearing choppers, and a massive array of 3 He linear position sensitive detectors. Novel features of the spectrometer include the use of a large gate valve between the sample and detector vacuum chambers and the placement of the detectors within the vacuum, both of which provide a window-free final flight path to minimize background scattering while allowing rapid changing of the sample and sample environment equipment. ARCS views the SNS decoupled ambient temperature water moderator, using neutrons with incident energy typically in the range from 15 to 1500 meV. This range, coupled with the large detector coverage, allows a wide variety of studies of excitations in condensed matter, such as lattice dynamics and magnetism, in both powder and single-crystal samples. Comparisons of early results to both analytical and Monte Carlo simulation of the instrument performance demonstrate that the instrument is operating as expected and its neutronic performance is understood. ARCS is currently in the SNS user program and continues to improve its scientific productivity by incorporating new instrumentation to increase the range of science covered and improve its effectiveness in data collection.

  18. Climate driven range divergence among host species affects range-wide patterns of parasitism

    Directory of Open Access Journals (Sweden)

    Richard E. Feldman

    2017-01-01

    Full Text Available Species interactions like parasitism influence the outcome of climate-driven shifts in species ranges. For some host species, parasitism can only occur in that part of its range that overlaps with a second host species. Thus, predicting future parasitism may depend on how the ranges of the two hosts change in relation to each other. In this study, we tested whether the climate driven species range shift of Odocoileus virginianus (white-tailed deer accounts for predicted changes in parasitism of two other species from the family Cervidae, Alces alces (moose and Rangifer tarandus (caribou, in North America. We used MaxEnt models to predict the recent (2000 and future (2050 ranges (probabilities of occurrence of the cervids and a parasite Parelaphostrongylus tenuis (brainworm taking into account range shifts of the parasite’s intermediate gastropod hosts. Our models predicted that range overlap between A. alces/R. tarandus and P. tenuis will decrease between 2000 and 2050, an outcome that reflects decreased overlap between A. alces/R. tarandus and O. virginianus and not the parasites, themselves. Geographically, our models predicted increasing potential occurrence of P. tenuis where A. alces/R. tarandus are likely to decline, but minimal spatial overlap where A. alces/R. tarandus are likely to increase. Thus, parasitism may exacerbate climate-mediated southern contraction of A. alces and R. tarandus ranges but will have limited influence on northward range expansion. Our results suggest that the spatial dynamics of one host species may be the driving force behind future rates of parasitism for another host species.

    Full Text Available The reaction rate of the 3He(α,γ7 Be reaction is important both in the Big Bang Nucleosynthesis (BBN and in the Solar hydrogen burning. There have been a lot of experimental and theoretical efforts to determine this reaction rate with high precision. Some long standing issues have been solved by the more precise investigations, like the different S(0 values predicted by the activation and in-beam measurement. However, the recent, more detailed astrophysical model predictions require the reaction rate with even higher precision to unravel new issues like the Solar composition. One way to increase the precision is to provide a comprehensive dataset in a wide energy range, extending the experimental cross section database of this reaction. This paper presents a new cross section measurement between Ecm = 2.5 − 4.4 MeV, in an energy range which extends above the 7Be proton separation threshold.

    Full Text Available The aim of this paper is to investigate the relationship between structural narratology and interdisciplinary studies. We will try to answer two main questions: What factors have been effective in narratology’s orientation toward interdisciplinary studies? Is this tendency the result of a possibility in narration or a methodological necessity? The movement of narratology to interdisciplinary is observable not only in new narratological tendencies but also in changes in structural theories. Therefore, this article will trace the roots of this tendency in the revises and critiques of these theories until 1970s. By tracing these changes it can be realized that the theories of structural narrotology have broken with idea of independence and self-sufficiency of literature and embraced other disciplines. The main factors in these changes are: attention to cultural elements and reading process in the perception of narrative structure. These considerations have been accompanied by some results; first, the main targets of narratology changed from investigating textual properties to reading and understanding the narration process; second, some disciplines and fields related to culture and mind studies found their way into narratology.

    2017-04-01

    During the past 12 years, we have been engaging secondary level science students (15 to 18 years old) in the extracurricular activities of our school's Earth and Space Sciences Club, providing them with some of the skills needed to excel in science, technology, engineering, arts, and mathematics (STEAM). Our approach includes the use of authentic scientific data, project based learning, and inquiry-centred activities that go beyond the models and theories present in secondary level textbooks. Moreover, the activities and projects carried out, being eminently practical, also function as an extension of the curriculum and frequently enable the demonstration of the applicability of several concepts taught in the classroom in real life situations. The tasks carried out during these activities and research projects often require the combination of two or more subjects, promoting an interdisciplinary approach to learning. Outside of the traditional classroom settings, through interdisciplinary explorations, students also gain hands-on experience doing real science. Thereby, during this time, we have been able to promote meaningful and lasting experiences and spark students' interest in a wide diversity of topics.

    Full Text Available The Adaptive Water Governance project is an interdisciplinary collaborative synthesis project aimed at identifying the features of adaptive governance in complex social-ecological institutional systems to manage for water-basin resilience. We conducted a systematic qualitative meta-analysis of the project's first set of published interdisciplinary studies, six North American basin resilience assessments. We sought to develop new knowledge that transcends each study, concerning two categories of variables: (1 the drivers of change in complex water-basin systems that affect systemic resilience; and (2 the features of adaptive governance. We have identified the pervasive themes, concepts, and variables of the systemic-change drivers and adaptive-governance features from these six interdisciplinary texts using qualitative methods of inductive textual analysis and synthesis. We produced synthesis frameworks for understanding the patterns that emerged from the basin assessment texts, as well as comprehensive lists of the variables that these studies uniformly or nearly uniformly addressed. These study results are cross-interdisciplinary in the sense that they identify patterns and knowledge that transcend several diverse interdisciplinary studies. These relevant and potentially generalizable insights form a foundation for future research on the dynamics of complex social-ecological institutional systems and how they could be governed adaptively.

    Full Text Available Inspired by the intersection of character, emotions, and logic, much like a Hungarian Rhapsody which is beautifully sad; this paper explores ethos, pathos, and logos in the context of Academic Globalization. As students of the world, an inter-disciplinary language is pivotal for inter-disciplinary communication. Given that the current state of the world stems primarily from miscommunications, it is imperative to launch a cognitive language tool which underscores global commonalities and mitigates cultural differences. Such a platform would foster interdisciplinary research, education, and communication. New paradigms would evolve, grounded in ethos, pathos, and logos. Like yin and yang, these states are interrelated, interacting, and interchanging learning spheres. Just as day and night blend at some point; just as the Parthenon epitomized Greek thought, celebrated the birthplace of democracy, and for the first time, depicted everyday citizens in friezes- underscoring their impactful role- ethos, pathos, and logos represent cross-disciplinary communication devices which synergistically transform and ignite academic globalization. The Literature Review links the concepts of ethos, pathos, and logos with the seminal work Lewis and his LMR framework, which has given birth to Cultureactive and subsequently to ICE [InterCultural Edge]. http://www.fuqua.duke.edu/ciber/programs/we_organize/ice/ Accessed February 14, 2014

    The Dead Sea region has faced substantial environmental challenges in recent decades, including water resource scarcity, ~1m annual decreases in the water level, sinkhole development, ascending-brine freshwater pollution, and seismic disturbance risks. Natural processes are significantly affected by human interference as well as by climate change and tectonic developments over the long term. To get a deep understanding of processes and their interactions, innovative scientific approaches that integrate disciplinary research and education are required. The research project DESERVE (Helmholtz Virtual Institute Dead Sea Research Venue) addresses these challenges in an interdisciplinary approach that includes geophysics, hydrology, and meteorology. The project is implemented by a consortium of scientific institutions in neighboring countries of the Dead Sea (Israel, Jordan, Palestine Territories) and participating German Helmholtz Centres (KIT, GFZ, UFZ). A new monitoring network of meteorological, hydrological, and seismic/geodynamic stations has been established, and extensive field research and numerical simulations have been undertaken. For the first time, innovative measurement and modeling techniques have been applied to the extreme conditions of the Dead Sea and its surroundings. The preliminary results show the potential of these methods. First time ever performed eddy covariance measurements give insight into the governing factors of Dead Sea evaporation. High-resolution bathymetric investigations reveal a strong correlation between submarine springs and neo-tectonic patterns. Based on detailed studies of stratigraphy and borehole information, the extension of the subsurface drainage basin of the Dead Sea is now reliably estimated. Originality has been achieved in monitoring flash floods in an arid basin at its outlet and simultaneously in tributaries, supplemented by spatio-temporal rainfall data.

  8. Fostering the Self-Renewal of Teachers: An Underutilized Approach to Innovating Interdisciplinary Education

    Directory of Open Access Journals (Sweden)

    David J. Waters

    2013-06-01

    Full Text Available Our goal is to call teachers’ attention to the need for selfrenewal, challenging them to consider it a necessary approach to innovating interdisciplinary education. Our prescription for sustained self-renewal: Each teacher assembles a gallery of intellectual heroes — gifted and articulate thinkers — to serve as their own life-long teachers. In this paper, we share our experience teaching a "skills course" to interdisciplinary graduate students in Purdue University’s Center on Aging and the Life Course. The course, titled "To See and To Seize Opportunities", exposes scholars-in-training to an array of skills and attitudes that foster self-renewal and peak performance. Leading educators must work hard to create better opportunities for self-renewal. By envisioning even our best teachers as unfinished and under construction, we open up a new dialogue situating the self-renewal of teachers at the very core of educational excellence across a broad range of disciplines. To innovate interdisciplinary education, we believe it is time for a curricular re-think, emphasizing the importance of a transdisciplinary skills course in which teachers and their students can explore transformative ideas on personal development and self-renewal — in the classroom together.

    Full Text Available As drivers of human civilization, Knowledge Management (KM processes have co-evolved in line with General-Purpose-Technologies (GPT, such as writing, printing, and information and communication systems. As evidenced by the recent shift from information scarcity to abundance, GPTs are capable of drastically altering societies due to their game-changing impact on our spheres of work and personal development. This paper looks at the prospect of whether a novel Personal Knowledge Management (PKM concept supported by a prototype system has got what it takes to grow into a transformative General-Purpose-Technology. Following up on a series of papers, the KM scenario of a decentralizing revolution where individuals and self-organized groups yield more power and autonomy is examined according to a GPT's essential characteristics, including a wide scope for improvement and elaboration (in people's private, professional and societal life, applicability across a broad range of uses in a wide variety of products and processes (in multi-disciplinary educational and work contexts, and strong complementarities with existing or potential new technologies (like organizational KM Systems and a proposed World Heritage of Memes Repository. The result portrays the PKM concept as a strong candidate due to its personal, autonomous, bottom-up, collaborative, interdisciplinary, and creativity-supporting approach destined to advance the availability, quantity, and quality of the world extelligence and to allow for a wider sharing and faster diffusion of ideas across current disciplinary and opportunity divides.

    2018-05-01

    The present work examines regional deposition within the nose for nasal sprays over a large and wide ranging parameter space by using numerical simulation. A set of 7 realistic adult nasal airway geometries was defined based on computed tomography images. Deposition in 6 regions of each nasal airway geometry (the vestibule, valve, anterior turbinate, posterior turbinate, olfactory, and nasopharynx) was determined for varying particle diameter, spray cone angle, spray release direction, particle injection speed, and particle injection location. Penetration of nasal spray particles through the airway geometries represented unintended lung exposure. Penetration was found to be relatively insensitive to injection velocity, but highly sensitive to particle size. Penetration remained at or above 30% for particles exceeding 10 μm in diameter for several airway geometries studied. Deposition in the turbinates, viewed as desirable for both local and systemic nasal drug delivery, was on average maximized for particles ranging from ~20 to 30 μm in diameter, and for low to zero injection velocity. Similar values of particle diameter and injection velocity were found to maximize deposition in the olfactory region, a potential target for nose-to-brain drug delivery. However, olfactory deposition was highly variable between airway geometries, with maximum olfactory deposition ranging over 2 orders of magnitude between geometries. This variability is an obstacle to overcome if consistent dosing between subjects is to be achieved for nose-to-brain drug delivery. Copyright © 2018 John Wiley & Sons, Ltd.

    2017-12-01

    We will summarize a multi-year research effort on wide-ranging observations of pre-earthquake processes. Based on space and ground data we present some new results relevant to the existence of pre-earthquake signals. Over the past 15-20 years there has been a major revival of interest in pre-earthquake studies in Japan, Russia, China, EU, Taiwan and elsewhere. Recent large magnitude earthquakes in Asia and Europe have shown the importance of these various studies in the search for earthquake precursors either for forecasting or predictions. Some new results were obtained from modeling of the atmosphere-ionosphere connection and analyses of seismic records (foreshocks /aftershocks), geochemical, electromagnetic, and thermodynamic processes related to stress changes in the lithosphere, along with their statistical and physical validation. This cross - disciplinary approach could make an impact on our further understanding of the physics of earthquakes and the phenomena that precedes their energy release. We also present the potential impact of these interdisciplinary studies to earthquake predictability. A detail summary of our approach and that of several international researchers will be part of this session and will be subsequently published in a new AGU/Wiley volume. This book is part of the Geophysical Monograph series and is intended to show the variety of parameters seismic, atmospheric, geochemical and historical involved is this important field of research and will bring this knowledge and awareness to a broader geosciences community.

    2009-01-01

    The Handbook of Signal Processing in Acoustics presents signal processing as it is practiced in the field of acoustics. The Handbook is organized by areas of acoustics, with recognized leaders coordinating the self-contained chapters of each section. It brings together a wide range of perspectives from over 100 authors to reveal the interdisciplinary nature of signal processing in acoustics. Success in acoustic applications often requires juggling both the acoustic and the signal processing parameters of the problem. This handbook brings the key issues from both into perspective and is complementary to other reference material on the two subjects. It is a unique resource for experts and practitioners alike to find new ideas and techniques within the diversity of signal processing in acoustics.

    Junges, Leandro; Gallas, Jason A C

    2015-01-01

    The dynamics of two mutually delay-coupled semiconductor lasers has been frequently studied experimentally, numerically, and analytically either for weak or strong detuning between the lasers. Here, we present a systematic numerical investigation spanning all detuning ranges. We report high-resolution stability diagrams for wide ranges of the main control parameters of the laser, as described by the Lang–Kobayashi model. In particular, we detail the parameter influence on dynamical performance and map the distribution of chaotic pulsations and self-generated periodic spiking with arbitrary periodicity. Special attention is given to the unfolding of regular pulse packages for both symmetric and non-symmetric configurations with respect to detuning. The influence of the delay –time on the self-organization of periodic and chaotic laser phases as a function of the coupling and detuning is also described in detail. (paper)

  1. Infrastructure Commons in Economic Perspective

    Science.gov (United States)

    Frischmann, Brett M.

    This chapter briefly summarizes a theory (developed in substantial detail elsewhere)1 that explains why there are strong economic arguments for managing and sustaining infrastructure resources in an openly accessible manner. This theory facilitates a better understanding of two related issues: how society benefits from infrastructure resources and how decisions about how to manage or govern infrastructure resources affect a wide variety of public and private interests. The key insights from this analysis are that infrastructure resources generate value as inputs into a wide range of productive processes and that the outputs from these processes are often public goods and nonmarket goods that generate positive externalities that benefit society as a whole. Managing such resources in an openly accessible manner may be socially desirable from an economic perspective because doing so facilitates these downstream productive activities. For example, managing the Internet infrastructure in an openly accessible manner facilitates active citizen involvement in the production and sharing of many different public and nonmarket goods. Over the last decade, this has led to increased opportunities for a wide range of citizens to engage in entrepreneurship, political discourse, social network formation, and community building, among many other activities. The chapter applies these insights to the network neutrality debate and suggests how the debate might be reframed to better account for the wide range of private and public interests at stake.

    Marine biota is able to concentrate /sup 210/Po to high levels, as 10/sup 3/-10/sup 5/ relative to sea water concentration. /sup 210/Po concentrations in mixed zooplankton reaches 34-51 Bq.kg/sup -1/ (fresh wt), special groups such as copepods reaching even higher concentrations /similar to/ 90 Bq.kg/sup -1/, whereas gelatinous zooplankton display /similar to/ 1 Bq.kg/sup -1/. Epipelagic teleosts feeding on plankton displayed the highest concentrations found in fish muscle, 2-21 Bq.kg/sup -1/. Contrasting with this, demersal teleosts and elasmobranchs display lower /sup 210/Po concentrations, in the ranges 0.5-7 Bq.kg/sup -1/ and 0.2-1.7 Bq.kg/sup -1/, respectively. Much higher concentrations can, however, be measured in fish liver, gonad, bone and piloric caecca, and small mesopelagic fish can reach /similar to/ 800 Bq.kg/sup -1/ on a whole-body basis. Due to these /sup 210/Po activity concentrations, dose equivalent rates delivered to biological tissues in marine organisms can vary widely, from 0.4 mSv.y/sup -1/ in gelatinous plankton up to 5.6 x 10/sup 3/ mSv.y/sup -1/ in the gut wall of sardines. It is concluded that in organisms living in the same ocean layer a wide range of internal radiation doses exists and it is essentially sustained by /sup 210/Po food-chain transfer. (author).

    2006-12-01

    Recently, an interdisciplinary group of faculty from the University of Idaho was awarded a major internal grant for their project "Water of the West (WoW)" to launch an interdisciplinary Water Resources Graduate Education Program. This Water Resources program will facilitate research and education to influence both the scientific understanding of the resource and how it is managed, and advance the decision-making processes that are the means to address competing societal values. By educating students to integrate environmental sciences, socio-economic, and political issues, the WoW project advances the University's land grant mission to promote economic and social development in the state of Idaho. This will be accomplished through novel experiential interdisciplinary education activities; creation of interdisciplinary research efforts among water resources faculty; and focusing on urgent regional problems with an approach that will involve and provide information to local communities. The Water Resources Program will integrate physical and biological sciences, social science, law, policy and engineering to address problems associated with stewardship of our scarce water resources. As part of the WoW project, faculty will: (1) develop an integrative problem-solving framework; (2) develop activities to broaden WR education; (3) collaborate with the College of Law to offer a concurrent J.D. degree, (4) develop a virtual system of watersheds for teaching and research, and (5) attract graduate students for team-based education. The new program involves 50 faculty from six colleges and thirteen departments across the university. This university-wide initiative is strengthened by collaboration with the Idaho Water Resources Research Institute, and participation from off-campus Centers in Idaho Falls, Boise, Twin Falls, and Coeur d'Alene. We hope this presentation will attract university faculty, water resources professionals, and others for stimulating discussions on

    Full Text Available This text covers the concepts of body and embodiment, creating a lexicon of words serving as instruments to think about the latest theatre studies. It discusses the distinction between body and flesh and their theoretical-practical combination in the notion of embodiment. Likewise, it is supported by works by Marcel Jousse, Richard Schechner, JeanMarie Pradier, among others, to extend the spectrum of possibilities of thinking about the body in the contemporary scene. Connections are made between Neurosciences, Ethnoscenology and Performance Studies, in particular from the concept of mirror neurons as an embodied simulation of actions and intentions, showing possibilities to expand theatrology by including the study of the relationship between actor and spectator in an interdisciplinary perspective.

  7. Development of dose monitoring system applicable to various radiations with wide energy ranges

    International Nuclear Information System (INIS)

    Sato, Tatsuhiko; Satoh, Daiki; Endo, Akira

    2006-01-01

    A new radiation dose monitor, designated as DARWIN (Dose monitoring system Applicable to various Radiations with WIde energy raNges), has been developed for real-time monitoring of doses in workspaces and surrounding environments of high energy accelerator facilities. DARWIN is composed of a phoswitch-type scintillation detector, which consists of liquid organic scintillator BC501A coupled with ZnS(Ag) scintillation sheets doped with 6 Li, and a data acquisition system based on a Digital-Storage-Oscilloscope. DARWIN has the following features: (1) capable of monitoring doses from neutrons, photons and muons with energies from thermal energy to 1 GeV, 150 keV to 100 MeV, and 1 MeV to 100 GeV, respectively, (2) highly sensitive with precision, and (3) easy to operate with a simple graphical user-interface. The performance of DARWIN was examined experimentally in several radiation fields. The results of the experiments indicated the accuracy and rapid response of DARWIN for measuring dose rates from neutrons, photons and muons with wide energies. With these properties, we conclude that DARWIN will be able to play a very important role for improving radiation safety in high energy accelerator facilities. (author)

  8. Flash flooding: Toward an Interdisciplinary and Integrated Strategy for Disaster Reduction in a Global Environmental Change Perspective

    Science.gov (United States)

    Ruin, Isabelle

    2014-05-01

    How do people answer to heavy precipitation and flood warnings? How do they adapt their daily schedule and activity to the fast evolution of the environmental circumstances? More generally, how do social processes interact with physical ones? Such questions address the dynamical interactions between hydro-meteorological variables, human perception and representation of the environment, and actual individual and social behavioral responses. It also poses the question of scales and hierarchy issues through seamless interactions between smaller and larger scales. These questions are relevant for both social and physical scientists. They are more and more pertinently addressed in the Global Environmental Change perspective through the concepts of Coupled Human And Natural Systems (CHANS), resilience or panarchy developped in the context of interdisciplinary collaborations. Nevertheless those concepts are complex and not easy to handle, specially when facing with operational goals. One of the main difficulty to advance these integrated approaches is the access to empirical data informing the processes at various scales. In fact, if physical and social processes are well studied by distinct disciplines, they are rarely jointly explored within similar spatial and temporal resolutions. Such coupled observation and analysis poses methodological challenges, specially when dealing with responses to short-fuse and extreme weather events. In fact, if such coupled approach is quite common to study large scale phenomenon like global change (for instance using historical data on green house gaz emissions and the evolution of temperatures worldwide), it is rarer for studing smaller nested sets of scales of human-nature systems where finer resolution data are sparse. Another problem arise from the need to produce comparable analysis on different case studies where social, physical and even cultural contexts may be diverse.

    Full Text Available The effect of the diameter of randomly arranged silver nanowires on the optical haze of silver nanowire transparent conductive films was studied. Proposed simulation model behaved similarly with the experimental results, and was used to theoretically study the optical haze of silver nanowires with diameters in the broad range from 30 nm and above. Our results show that a thickening of silver nanowires from 30 to 100 nm results in the increase of the optical haze up to 8 times, while from 100 to 500 nm the optical haze increases only up to 1.38. Moreover, silver nanowires with diameter of 500 nm possess up to 5% lower optical haze and 5% higher transmittance than 100 nm thick silver nanowires for the same 10-100 Ohm/sq sheet resistance range. Further thickening of AgNWs can match the low haze of 30 nm thick AgNWs, but at higher transmittance. The results obtained from this work allow deeper analysis of the silver nanowire transparent conductive films from the perspective of the diameter of nanowires for various optoelectronic devices.

  11. The work ability divide: holistic and reductionistic approaches in Swedish interdisciplinary rehabilitation teams.

    Stakeholder cooperation in return to work has been increasingly emphasised in research, while studies on how such cooperation works in practise are scarce. This article investigates the relationship between professionals in Swedish interdisciplinary rehabilitation teams, and the aim of the article is to determine the participants' definitions and uses of the concept of work ability. The methods chosen were individual interviews with primary health care centre managers and focus groups with twelve interdisciplinary teams including social insurance officers, physicians, physiotherapists, occupational therapists, medical social workers and coordinators. The results show that the teams have had problems with reaching a common understanding of their task, due to an inherent tension between the stakeholders. This tension is primarily a result of two factors: divergent perspectives on work ability between the health professionals and the Social Insurance Agency, and different approaches to cooperative work among physicians. Health professionals share a holistic view on work ability, relating it to a variety of factors. Social insurance officers, on the other hand, represent a reductionistic stance, where work ability is reduced to medical status. Assessments of work ability therefore tend to become a negotiation between insurance officers and physicians. A suggestion from the study is that the teams, with proper education, could be used as an arena for planning and coordinating return-to-work, which would strengthen their potential in managing the prevention of work disability.

    2009-07-01

    To explore perspectives on music therapy as a nursing intervention in adult cancer care and to expand and integrate knowledge and understanding about music therapy as an adjunctive intervention in adult cancer nursing care. Published nursing articles. Medical and nursing journals have reported on research related to music and its effect as a nursing intervention. However, this research often lacks a musical context (i.e., knowledge and understanding from a musical perspective). Music therapy is not a consistent concept. Perspectives on the meanings of music therapy vary according to knowledge and scientific orientation. The perspective may influence the character and methodology of the music therapy intervention as well as the understanding of its results. To fully develop music therapy as an adjunct intervention in adult cancer care, interdisciplinary cooperation between nurses and music therapists should be supported on clinical and educational levels.

    2014-11-01

    Full Text Available In this study, we develop a clamped–clamped beam-type piezoelectric vacuum pressure sensing element. The clamped–clamped piezoelectric beam is composed of a PZT layer and a copper substrate. A pair of electrodes is set near each end. An input voltage is applied to a pair of electrodes to vibrate the piezoelectric beam, and the output voltage is measured at the other pair. Because the viscous forces on the piezoelectric beam vary at different air pressures, the vibration of the beam depends on the vacuum pressure. The developed pressure sensor can sense a wide range of pressure, from 6.5 × 10−6 to 760 Torr. The experimental results showed that the output voltage is inversely proportional to the gas damping ratio, and thus, the vacuum pressure was estimated from the output voltage.

    Interdisciplinary rounds (IDR) provide a means to assemble hospital team members and improve collaboration. Little is known about teamwork during IDR. To evaluate and characterize teamwork during IDR. Cross-sectional observational study. Six medical units which had implemented structured interdisciplinary rounds (SIDR). We adapted the Observational Teamwork Assessment for Surgery (OTAS) tool, a behaviorally anchored rating scale shown to be reliable and valid in surgical settings. OTAS provides scores ranging from 0 to 6 (0 = problematic behavior; 6 = exemplary behavior) across 5 domains (communication, coordination, cooperation/backup behavior, leadership, and monitoring/situational awareness) and for prespecified subteams. Two researchers conducted direct observations using the adapted OTAS tool. We conducted 7-8 independent observations for each unit (total = 44) and 20 joint observations. Inter-rater reliability was excellent at the unit level (Spearman's rho = 0.75), and good across domains (rho = 0.53-0.68) and subteams (rho = 0.53-0.76) with the exception of the physician subteam, for which it was poor (rho = 0.35). Though teamwork scores were generally high, we found differences across units, with a median (interquartile range [IQR]) 4.5 (3.9-4.9) for the lowest and 5.4 (5.3-5.5) for the highest performing unit (P teamwork during SIDR across units, domains, and most subteams. Variation in performance suggests a need to improve consistency of teamwork and emphasizes the importance of leadership. Copyright © 2012 Society of Hospital Medicine.

    There are many challenges to conducting inter- or multi-disciplinary research because basic research, applied research, management processes, disciplines, and even sub-disciplines have been "siloed" for so long that many research and management professionals find it difficult to communicate common interests and research needs. It is clear that the next generation of researchers must overcome these disciplinary biases and engage in more open dialogue with other disciplines and the management community in order to be better positioned to collaborate, speak a common language, and understand each other's needs. The U.S. Department of the Interior's South Central Climate Science Center recently conducted a professional development workshop for 28 early-career researchers involved in climate-related research across the South-Central U.S. The participants consisted of graduate students, postdocs, and junior faculty representing 17 different natural and social science disciplines and seven Universities/Institutions. The workshop provided the participants with guidance and instruction on how to overcome the identified challenges in conducting "actionable" research and how to better navigate multi-institutional and multi- or inter-disciplinary research. The workshop was comprised of: (1) a series of instructional presentations organized into themed sessions; (2) two keynote addresses to provide a broader perspective; (3) a real-world case study activity; (4) individual and group projects/presentations; and (5) field trips. In addition, we purposely created informal opportunities for participants to network, which met the goal of facilitating interdisciplinary interactions. An overview of the workshop experience will be provided, including a focus on those aspects leading to its ultimate success and recommendations for how to develop and implement a similar early-career workshop for your own purposes.

    The majority of post-acute hip fracture rehabilitation in the US is delivered in skilled nursing facilities (SNFs). Currently, there are limited guidelines that equip occupational and physical therapy practitioners with a summary of what constitutes evidence-based high quality rehabilitation. Thus, this study aimed to identify rehabilitation practitioners' perspectives on the practices that constitute high quality hip fracture rehabilitation. Focus groups were conducted with 99 occupational and physical therapy practitioners working in SNFs in southern California. Purposive sampling of facilities was conducted to capture variation in key characteristics known to impact care delivery for this patient population (e.g., financial resources, staffing, and patient case-mix). Questions aimed to elicit practitioners' perspectives on high quality hip fracture rehabilitation practices. Each session was audio-recorded and transcribed. Data were systematically analyzed using a modified grounded theory approach. Seven themes emerged: objectives of care; first 72 h; positioning, pain, and precautions; use of standardized assessments; episode of care practices; facilitating insight into progress; and interdisciplinary collaboration. Clinical guidelines are critical tools to facilitate clinical decision-making and achieve desired patient outcomes. The findings of this study highlight the practitioners' perspective on what constitutes high quality hip fracture rehabilitation. This work provides critical information to advance the development of stakeholder-driven rehabilitation clinical guidelines. Future research is needed to verify the findings from other stakeholders (e.g., patients), ensure the alignment of our findings with current evidence, and develop measures for evaluating their delivery and relationship to desired outcomes. Implications for Rehabilitation This study highlights occupational and physiotherapy therapy practitioners' perspectives on the cumulative best

    Full Text Available The thematic issue presents a psycho-societal approach to qualitative empirical research in several areas of everyday social life. It is an approach which integrates a theory of subjectivity and an interpretation methodology which integrates hermeneutic experiences from text analysis and psychoanalysis. Its particular focus is on subjectivity—as an aspect of the research object and as an aspect of the research process. By the term "approach" is indicated the intrinsic connection between the theorizing of an empirical object and the reflection of the research process and the epistemic subject. In terms of methodology it revives the themes originally launched in FQS exactly ten years ago: "Subjectivity and Reflectivity in Qualitative Research" (BREUER, MRUCK & ROTH, 2002; MRUCK & BREUER, 2003. This editorial introduction presents the intellectual background of the psycho-societal methodology, reflects on its relevance and critical perspectives in a contemporary landscape of social science, and comments the way in which an international and interdisciplinary research group has developed this approach to profane empirical research.

    There are exigent reasons to foster lesbian, gay, bisexual, and transgender (LGBT) competence, training, and ethical care for health professionals within an interdisciplinary paradigm. LGBT individuals experience serious health and psychosocial disparities; moreover, these inequalities can be amplified when other aspects of diversity such as race, ethnicity, age, gender, religion, disability, and socioeconomic status intersect with sexual orientation and gender identity (Institute of Medicine [IOM], 2011). While the origins of LGBT health and psychosocial disparities are manifold, deficiencies in professional training, ethical care, and clinical competence are underlying contributors (IOM, 2011). In addition, LGBT clinical competency advancements are often siloed within the various health care disciplines-thus advances by one group of health professionals often have limited impact for those practicing in different health and human service fields. This special issue explores LGBT clinical competence, professional training, and ethical care within an interdisciplinary context and, to our knowledge, represents the first attempt to address LGBT clinical competence from a multidisciplinary health care perspective.

    ENTRIA, short for ''Disposal Options for Radioactive Residues: Interdisciplinary Analyses and Development of Evaluation Principles'', is a joint project of twelve institutes or departments of German universities and research institutions as well as a partner from Switzerland. The fundamentally new approach here is the plurality of represented disciplines. ENTRIA analyzes radioactive waste management subjects from the viewpoint of natural sciences, engineering, arts, law and social science. ENTRIA works independently from politics, operators und interest groups. ENTRIA performs purely scientific research analyzing the three most important radioactive waste management option:''Final disposal in deep geological formations without any arrangements for retrieval (maintenance-free deep geological disposal)'', ''disposal in deep geological formations with arrangements for monitoring and retrieval'' and ''surface storage''. Based on these options ENTRIA developed generic ''reference models'' and generic host-rockdependent container models (ENCON). All these models are of generic character, but are elaborated to an extent, e.g. with respect to reversibility time scales, as is necessary for a comparative differentiated evaluation. Long-term surface storage is considered and evaluated because of the increasingly apparent need to address interim storage not only as (temporary) alternative, but also as a necessary part of the overall process. Besides disciplinary work packages performed in ENTRIA several tasks combine the expertise and perspective of disciplines which could classically be considered ''far apart''. A key task is the creation of interdisciplinary evaluation principles. This article provides insight into interdisciplinary working within ENTERIA and describes the present status of this work from the perspective of the authors. However, this is not

  12. Determining the bounds of skilful forecast range for probabilistic prediction of system-wide wind power generation

    Directory of Open Access Journals (Sweden)

    Dirk Cannon

    2017-06-01

    Full Text Available State-of-the-art wind power forecasts beyond a few hours ahead rely on global numerical weather prediction models to forecast the future large-scale atmospheric state. Often they provide initial and boundary conditions for nested high resolution simulations. In this paper, both upper and lower bounds on forecast range are identified within which global ensemble forecasts provide skilful information for system-wide wind power applications. An upper bound on forecast range is associated with the limit of predictability, beyond which forecasts have no more skill than predictions based on climatological statistics. A lower bound is defined at the lead time beyond which the resolved uncertainty associated with estimating the future large-scale atmospheric state is larger than the unresolved uncertainty associated with estimating the system-wide wind power response to a given large-scale state.The bounds of skilful ensemble forecast range are quantified for three leading global forecast systems. The power system of Great Britain (GB is used as an example because independent verifying data is available from National Grid. The upper bound defined by forecasts of GB-total wind power generation at a specific point in time is found to be 6–8 days. The lower bound is found to be 1.4–2.4 days. Both bounds depend on the global forecast system and vary seasonally. In addition, forecasts of the probability of an extreme power ramp event were found to possess a shorter limit of predictability (4.5–5.5 days. The upper bound on this forecast range can only be extended by improving the global forecast system (outside the control of most users or by changing the metric used in the probability forecast. Improved downscaling and microscale modelling of the wind farm response may act to decrease the lower bound. The potential gain from such improvements have diminishing returns beyond the short-range (out to around 2 days.

  15. Towards Core Modelling Practices in Integrated Water Resource Management: An Interdisciplinary View of the Modelling Process

    Jakeman, A. J.; Elsawah, S.; Pierce, S. A.; Ames, D. P.

    2016-12-01

    The National Socio-Environmental Synthesis Center (SESYNC) Core Modelling Practices Pursuit is developing resources to describe core practices for developing and using models to support integrated water resource management. These practices implement specific steps in the modelling process with an interdisciplinary perspective; however, the particular practice that is most appropriate depends on contextual aspects specific to the project. The first task of the pursuit is to identify the various steps for which implementation practices are to be described. This paper reports on those results. The paper draws on knowledge from the modelling process literature for environmental modelling (Jakeman et al., 2006), engaging stakeholders (Voinov and Bousquet, 2010) and general modelling (Banks, 1999), as well as the experience of the consortium members. We organise the steps around the four modelling phases. The planning phase identifies what is to be achieved, how and with what resources. The model is built and tested during the construction phase, and then used in the application phase. Finally, models that become part of the ongoing policy process require a maintenance phase. For each step, the paper focusses on what is to be considered or achieved, rather than how it is performed. This reflects the separation of the steps from the practices that implement them in different contexts. We support description of steps with a wide range of examples. Examples are designed to be generic and do not reflect any one project or context, but instead are drawn from common situations or from extremely different ones so as to highlight some of the issues that may arise at each step.

    2002-01-01

    Patient violence is a growing problem in healthcare institutions. Incidents of violence lead to injuries and increased operating costs. An innovative organizational approach to this problem is inclusion of interdisciplinary competency-based staff education and practice, as a key component of a comprehensive violence prevention program.Interdisciplinary competencies include a variety of behavioral responses, aimed at prevention, environmental, interpersonal, and physical interventions and postvention techniques for aggression and violence. Methods to maintain, monitor, document, and improve staff performance and skills are delineated. Organizational investment in such interdisciplinary competency-based education and practice evolves over time. Results include fewer incidents and injuries and enhanced interdisciplinary cooperation.

  18. A wide-range embrittlement trend curve for western RPV steels

    International Nuclear Information System (INIS)

    Kirk, M.T.

    2011-01-01

    Embrittlement trend curves (ETCs) are used to estimate neutron irradiation embrittlement as a function of both exposure (fluence, flux, temperature, ...) and composition variables. ETCs provide information needed to assess the structural integrity of operating nuclear reactors, and to determine their suitability for continued safe operation. Past efforts on ETC development in the United States have used data drawn from domestic licensees. While this approach has addressed past needs well, future needs such as power up-rates, license extensions to 60 years and beyond, and the use of low copper materials in new reactors produce future operating conditions for the US reactor fleet that may differ from past experience, suggesting that data from sources other than licensee surveillance programs may be needed. In this paper we draw together embrittlement data expressed in terms of ΔT41J and ΔYS from a wide variety of data sources as a first step in examining future embrittlement trends. We develop a 'wide range' ETC based on a collection of over 2500 data. We assess how well this ETC models the whole database, as well as significant data subsets. Comparisons presented herein indicate that a single algebraic model, denoted WR-C(5), represents reasonably well both the trends evident in the data overall as well as trends exhibited by four special data subsets. The WR-C(5) model indicates the existence of trends in high fluence data (Φ > 2-3*10 19 n/cm 2 , E > 1 MeV) that are not as apparent in the US surveillance data due to the limited quantity of ΔT30 data measured at high fluence in this dataset. Additionally, WR-C(5) models well the trends in both test and power reactor data despite the fact it has not term to account for flux. It is suggested that one appropriate use of the WR-C(5) trend curve may include the design irradiation studies to validate or refute the findings presented herein. Additionally, WR-C(5) could be used, along with other information (e.g., other

    This paper describes a wide dynamic range neutron monitor based on a BF 3 neutron detector. The detector is used in current mode, and front-end electronics based on a logarithmic amplifier are used in order to have a measurement capability ranging over many orders of magnitude. The system has been calibrated at the Polytechnic of Milan, CESNEF, with an AmBe neutron source, and has been tested in a pulsed field at the PUNITA facility at JRC, Ispra. The detector has achieved a dynamic range of over 6 orders of magnitude, being able to measure single neutron pulses and showing saturation-free response for a reaction rate up to 10 6 s -1 . It has also proved effective in measuring the PUNITA facility pulse integral fluence.

  2. The Development of Interdisciplinary Teaching Approaches among Pre-service Science and Mathematics Teachers

    Science.gov (United States)

    Miranda Martins, Dominique

    This study sought to understand how a group of pre-service teachers in a combined secondary science and mathematics teaching methods course conceptualized and experienced interdisciplinary approaches to teaching. Although knowing how to plan interdisciplinary activities is an essential teaching practice in Quebec, these pre-service teachers faced many challenges during the process of learning to teach with this approach. By using two interdisciplinary frameworks (Nikitina, 2005; Boix Mansilla & Duraising, 2007), I qualitatively analyzed the development of the pre-service teachers' prior and emerging ideas about interdisciplinarity and their ability to plan interdisciplinary teaching activities. The provincial curriculum and issues related to time greatly shaped students' conceptions about interdisciplinarity in the classroom and constrained their ability to plan for and envision the enactment of interdisciplinary lessons in secondary science and mathematics classes. In addition, images of themselves as content-specialists, self-efficacy beliefs in relation to interdisciplinary teaching, and student learning as a source of teacher motivation emerged as key factors promoting or interrupting the development of interdisciplinary teaching approaches. Examination of these factors highlights the need for teacher-education programs to provide opportunities for pre-service teachers to explore how they see themselves as educators, increase their instructional self-efficacy beliefs, and motivate them to teach in an interdisciplinary fashion. Keywords: interdisciplinary teaching, student-teachers, curriculum, teacher-education program, self-efficacy, motivation.

  4. Fast negative feedback enables mammalian auditory nerve fibers to encode a wide dynamic range of sound intensities.

    Directory of Open Access Journals (Sweden)

    Mark Ospeck

    Full Text Available Mammalian auditory nerve fibers (ANF are remarkable for being able to encode a 40 dB, or hundred fold, range of sound pressure levels into their firing rate. Most of the fibers are very sensitive and raise their quiescent spike rate by a small amount for a faint sound at auditory threshold. Then as the sound intensity is increased, they slowly increase their spike rate, with some fibers going up as high as ∼300 Hz. In this way mammals are able to combine sensitivity and wide dynamic range. They are also able to discern sounds embedded within background noise. ANF receive efferent feedback, which suggests that the fibers are readjusted according to the background noise in order to maximize the information content of their auditory spike trains. Inner hair cells activate currents in the unmyelinated distal dendrites of ANF where sound intensity is rate-coded into action potentials. We model this spike generator compartment as an attenuator that employs fast negative feedback. Input current induces rapid and proportional leak currents. This way ANF are able to have a linear frequency to input current (f-I curve that has a wide dynamic range. The ANF spike generator remains very sensitive to threshold currents, but efferent feedback is able to lower its gain in response to noise.

  5. [Resilience: an interdisciplinary approach to concept and findings].

    2012-01-01

    First, the concept of the term "resilience" is introduced and summarized as an adaptive, dynamic "buffering process" of children's mental power of resistance against biological, psychological and psychosocial development risks. Subsequently, based on a critical discussion of the current research findings, protective factors are presented, which is followed by an approach to the concept of resilience from interdisciplinary perspectives. The latest findings from developmental neurobiology show that genetic as well as environmental factors have their important share in the development of resilience. This builds a bridge to the consideration of resilience with regard to attachment theory. Accordingly secure attachment could be seen as a condition for a resilient conduct of life. In this context, the concept of "earned security" is additionally taken into account. Furthermore, the relevance of resilience for the field of pedagogics is shortly and critically considered. With reference to a psychoanalytic approach to the concept of resilience self-regulation, internal integrity, mentalization and self-reflection are elaborated on, as well as the similarity to the psychoanalytic concept of ego strength. In conclusion, a critical discussion of the concept of resilience and its benefits as well as potential risks related to it is presented.

    Ag- and Nb-doped TiCN coatings with about 2 at.% of Nb and Ag contents varied between 4.0 and 15.1 at.% were designed as promising materials for tribological applications in a wide temperature range. We report on the structure, mechanical, and tribological properties of TiNbCN-Ag coatings fabricated by simultaneous co-sputtering of TiC0.5 + 10%Nb2C and Ag targets in comparison with those of Ag-free coating. The tribological characteristics were evaluated during constant-temperature tests both at room temperature and 300 °C, as well as during dynamic temperature ramp tests in the range of 25-700 °C. The coating structure and elemental composition were studied by means of X-ray diffraction, scanning and transmission electron microscopy, and glow discharge optical emission spectroscopy. The coating microstructures and elemental compositions inside wear tracks, as well as the wear products, were examined by scanning electron microscopy, energy-dispersive spectroscopy, and Raman spectroscopy. We demonstrate that simultaneous alloying with Nb and Ag permits to overcome the main drawbacks of TiCN coatings such as their relatively high values of friction coefficient at elevated temperatures and low oxidation resistance. It is shown that a relatively high amount of Ag (15 at.%) is required to provide enhanced tribological behavior in a wide temperature range of 25-700 °C. In addition, the prepared Ag-doped coatings demonstrated active oxidation protection and self-healing functionality due to the segregation of Ag metallic particles in damage areas such as cracks, pin-holes, or oxidation sites.

    Full Text Available In this study is discussed the relationship between curriculum, Interdisciplinarity, and Technology based upon an epistemological, methodological, and ontological perspective. Reasoned on the studies by Sacristán (2000, and Moreira and Silva (1990, this work reports the main theories to the curriculum and their applications on the everyday school. The interdisciplinary, supported by the work by Fazenda (2001,2014, points to the possible complementarity between knowledge and effectiveness of the partnership as essential to an intentional and contextualized practice. Valente (1993 and Silva (2002 stress out that the technology must be integrated into the curriculum and must contribute to the discussion that involves the everyday school.  Based upon a qualitative perspective, it is discussed two pedagogical practices carried out in computer labs in two classes of elementary and middle schools of a private school branch, one of the fifth and another of the eighth grades. The practices have shown: i the importance of the partnership between teachers; ii the need to work into thematics coming from critical perspective of the curriculum; and iii the possibilities to use the technology offers pedagogical practices and development of the autonomy of students, which contribute to their formation and to the own formation of the teachers.

    2012-09-01

    Dramatic advances are in the horizon resulting from rapid pace of development of several technologies, including, computing, communication, mobile, robotic, and interactive technologies. These advances, along with the trend towards convergence of traditional engineering disciplines with physical, life and other science disciplines will result in the development of new interdisciplinary fields, as well as in new paradigms for engineering practice in the coming intelligence/convergence era (post-information age). The interdisciplinary fields include Cyber Engineering, Living Systems Engineering, Biomechatronics/Robotics Engineering, Knowledge Engineering, Emergent/Complexity Engineering, and Multiscale Systems engineering. The paper identifies some of the characteristics of the intelligence/convergence era, gives broad definition of convergence, describes some of the emerging interdisciplinary fields, and lists some of the academic and other organizations working in these disciplines. The need is described for establishing a Hierarchical Cyber-Physical Ecosystem for facilitating interdisciplinary collaborations, and accelerating development of skilled workforce in the new fields. The major components of the ecosystem are listed. The new interdisciplinary fields will yield critical advances in engineering practice, and help in addressing future challenges in broad array of sectors, from manufacturing to energy, transportation, climate, and healthcare. They will also enable building large future complex adaptive systems-of-systems, such as intelligent multimodal transportation systems, optimized multi-energy systems, intelligent disaster prevention systems, and smart cities.

    2017-12-01

    InTeGrate supports integrated interdisciplinary learning about resource and environmental issues across the undergraduate curriculum to create a sustainable and just civilization. The project has developed teaching materials and examples of their use in programs and is currently engaged in a suite of activities that support use of these resources in improving undergraduate Earth education. Thirty-three sets of teaching materials supporting instruction over time periods of 2 weeks to a full semester have been developed by teams of faculty and peer-reviewed to ensure strong research-based pedagogic design and attention to five design principles: 1) address one or more grand challenges involving the Earth and society, 2) develop student ability to address interdisciplinary problems, 3) improve student understanding of the nature and methods of science and developing geoscientific habits of mind, 4) make use of authentic and credible science data to learn central concepts in the context of scientific methods of inquiry, and, 5) incorporate systems thinking. They have been tested in a wide variety of institutional and disciplinary settings and are documented with instructor notes describing adaptation for specific settings. All published materials passed a review for scientific accuracy. Sixteen program models demonstrate strategies for strengthening learning about Earth and sustainability at scales ranging from a department to an interinstitutional collaboration. These examples document the use of InTeGrate resources in the development and evaluation of these programs. A synthesis of lessons learned by these projects addresses strategies for teaching about the Earth across the curriculum. InTeGrate is currently supporting use of ideas and resources developed over the past six years of project work through a webinar series, workshops at professional society meetings, a traveling workshop program for departments and regions, a set of online learning communities and

  10. The adoption of an interdisciplinary instructional model in secondary education

    Misicko, Martin W.

    This study describes the experiences of a secondary high school involved in the adoption of an interdisciplinary curriculum. An interdisciplinary curriculum is defined as both the precalculus and physics curriculums taught collaboratively throughout the school year. The students' academic performances were analyzed to gage the success of the interdisciplinary model. The four year study compared students taught precalculus in a traditional discipline-based classroom versus those facilitated in an interdisciplinary precalculus/physics model. It also documents the administrative changes necessary in restructuring a high school to an interdisciplinary team teaching model. All of the students in both pedagogical models received instruction from the same teacher, and were given identical assessment materials. Additionally, the curriculum guidelines and standards of learning were duplicated for both models. The primary difference of the two models focused on the applications of mathematics in the physics curriculum. Prerequisite information was compared in both models to ensure that the students in the study had comparable qualifications prior to the facilitation of the precalculus curriculum. Common trends were analyzed and discussed from the student's performance data. The students enrolled in the interdisciplinary model appeared to outperform the discipline-based students in common evaluative assessments. The themes and outcomes described in this study provide discussion topics for further investigation by other school districts. Further study is necessary to determine whether scheduling changes may have influenced student performances, and to examine whether other content areas may experience similar results.

    In the present study we report the fabrication and characterization of no-core fiber sensor (NCFS) using smart hydrogel coating for pH measurement. The no-core fiber (NCF) is stubbed between two single-mode fibers with SMA connector before immobilizing of smart hydrogel. The wavelength interrogation technique is used to calculate the sensitivity of the proposed sensor. The result shows a high sensitivity of 1.94 nm/pH for a wide range of pH values varied from 3 to 10 with a good linear response. In addition to high sensitivity, the fabricated sensor provides a fast response time with a good stability, repeatability and reproducibility.

    2018-04-01

    Full Text Available Primary literacy in Macedonian education is in decline. This assertion has been proved both by the abstract theory, and by the concrete empirical data. Educational reforms in the national curriculum are on their way, and the implementation of the method of global reading is one of the main innovations. Misunderstanding of this method has led it its being criticized as a foreign import and as unnatural and incongruous for the specificities of the Macedonian language. We think that this argument is wrong. That is why this paper is going to extrapolate and explain the method of global learning and its basis in pedagogy, philosophy, psychology, anthropology and linguistics. The main premise of this paper is the relation of the part to the whole, understood from the different perspectives of philosophy, psychology, linguistics and anthropology. The theories of Kant, Cassirer, Bruner, Benveniste and Geertz are going to be considered in the context of the part – whole problem, by themselves, and also in their relation to the method of global reading.

    2013-01-01

    Dispersal of plants and animals is one of the most fascinating subjects in ecology. It has long been recognized as an important factor affecting ecosystem dynamics. Dispersal is apparently a phenomenon of biological origin; however, because of its complexity, it cannot be studied comprehensively by biological methods alone. Deeper insights into dispersal properties and implications require interdisciplinary approaches involving biologists, ecologists and mathematicians. The purpose of this book is to provide a forum for researches with different backgrounds and expertise and to ensure further advances in the study of dispersal and spatial ecology. This book is unique in its attempt to give an overview of dispersal studies across different spatial scales, such as the scale of individual movement, the population scale and the scale of communities and ecosystems. It is written by top-level experts in the field of dispersal modeling and covers a wide range of problems ranging from the identification of Levy walks...

  15. Intracranial aneurysms: optimized diagnostic tools call for thorough interdisciplinary treatment strategies.

    2011-09-01

    Intracranial aneurysms (IAs) require deliberately selected treatment strategies as they are incrementally found prior to rupture and deleterious subarachnoid haemorrhage (SAH). Multiple and recurrent aneurysms necessitate both neurointerventionalists and neurosurgeons to optimize aneurysmal occlusion in an interdisciplinary effort. The present study was conducted to condense essential strategies from a single neurovascular centre with regard to the lessons learned. Medical charts of 321 consecutive patients treated for IAs at our centre from September 2008 until December 2010 were retrospectively analysed for clinical presentation of the aneurysms, multiplicity and treatment pathways. In addition, a selective Medline search was performed. A total of 321 patients with 492 aneurysms underwent occlusion of their symptomatic aneurysm: 132 (41.1%) individuals were treated surgically, 189 (58.2%) interventionally; 138 patients presented with a SAH, of these 44.2% were clipped and 55.8% were coiled. Aneurysms of the middle cerebral artery were primarily occluded surgically (88), whereas most of the aneurysms of the internal carotid artery and anterior communicating artery (114) were treated endovascularly. Multiple aneurysms (range 2-5 aneurysms/individual) were diagnosed in 98 patients (30.2%). During the study period 12 patients with recurrent aneurysms were allocated to another treatment modality (previously clip to coil and vice versa). Our data show that successful interdisciplinary occlusion of IAs is based on both neurosurgical and neurointerventional therapy. In particular, multiple and recurrent aneurysms require tailored individual approaches to aneurysmal occlusion. This is achieved by a consequent interdisciplinary pondering of the optimal strategy to occlude IAs in order to prevent SAH.

    A mixture of dilauroyl phosphatidylcholine (DLPC) and 3-(cholamidopropyl)dimethylammonio-2-hydroxyl-1-propane sulfonate (CHAPSO) in water forms disc shaped bicelles that become ordered at high magnetic fields over a wide range of temperatures. As illustrated for the FK506 binding protein (FKBP), large residual dipolar couplings can be measured for proteins dissolved in low concentrations (5% w/v) of a DLPC/CHAPSO medium at a molar ratio of 4.2:1. This system is especially useful for measuring residual dipolar couplings for molecules that are only stable at low temperatures.

  2. Novel Cross-Type Network for Wide-Tuning-Range Reconfigurable Multiband Antennas

    Directory of Open Access Journals (Sweden)

    Chieh-Sen Lee

    2014-01-01

    Full Text Available This paper presents a cross-type network design with a novel reconfigurable functionality to realize a tunable multiband antenna. By attaching a reconfigurable network at the feeding port of a broadband antenna, multi-input impedance adjustment enables the production of multimatching operating bands. Each band can be independently controlled by a single component with a considerably wide tuning range and high selectivity. The experiments in this study involved using an ultra-wideband (UWB antenna connected to the proposed cross-type network. The tunable antenna operates in a dual band of fL (1.39 to 2.34 GHz and fH (2.1 to 3.6 GHz with tunable frequency ratios of 168% and 132%, respectively. The average bandwidths at fL and fH are approximately 50 MHz and 148 MHz, respectively, implying narrowband operation. The measured radiation pattern revealed that the tunable antenna exhibits a nearly omnidirectional radiation pattern at both 1.8 and 3.5 GHz. The network circuit architecture can be extended to the multiband function type by adopting this matching approach. The amount of shunt matches determines the number of operation bands.

  3. Development of a wide range vortex shedding flowmeter for high temperature helium gas

    Energy Technology Data Exchange (ETDEWEB)

    1981-07-01

    A flowmeter was required to measure recirculating helium gas flow over a wide range of conditions in a gas-cooled fast reactor (GCFR) core flow simulator, the ORNL Core Flow Test Loop (CFTL). The flow measurement requirements of the CFTL exceeded the proven performance of any single conventional flowmeter. Therefore, a special purpose vortex shedding flowmeter (VSFM) was developed. A single flowmeter capable of meeting all the CFTL requirements would provide significant economic and performance advantages in the operation of the loop. The development, conceptual design, and final design of a modified VSFM are described. The results of extensive flow calibration of the flowmeter at the Colorado Engineering Experiment Station (CEES) are presented. The report closes with recommendations for application of the VSFM to the CFTL and for future development work.

    2018-02-01

    The aim of this study is to derive a consensus on an interdisciplinary competency framework regarding a holistic approach for audiological rehabilitation (AR), which includes disciplines from medicine, engineering, social sciences and humanities. We employed a modified Delphi method. In the first round survey, experts were asked to rate an initial list of 28 generic interdisciplinary competencies and to propose specific knowledge areas for AR. In the second round, experts were asked to reconsider their answers in light of the group answers of the first round. An international panel of 27 experts from different disciplines in AR completed the first round. Twenty-two of them completed the second round. We developed a competency framework consisting of 21 generic interdisciplinary competencies grouped in five domains and nine specific competencies (knowledge areas) in three clusters. Suggestions for the implementation of the generic competencies in interdisciplinary programmes were identified. This study reveals insights into the interdisciplinary competencies that are unique for AR. The framework will be useful for educators in developing interdisciplinary programmes as well as for professionals in considering their lifelong training needs in AR.

  5. Interdisciplinary Interactions During R&D and Early Design of Large Engineered Systems

    McGowan, Anna-Maria Rivas

    2014-01-01

    Designing Large-Scale Complex Engineered Systems (LaCES) such as aircraft and submarines requires the input of thousands of engineers and scientists whose work is proximate in neither time nor space. Comprehensive knowledge of the system is dispersed among specialists whose expertise is in typically one system component or discipline. This study examined the interactive work practices among such specialists seeking to improve engineering practice through a rigorous and theoretical understanding of current practice. This research explored current interdisciplinary practices and perspectives during R&D and early LaCES design and identified why these practices and perspectives prevail and persist. The research design consisted of a three-fold, integrative approach that combined an open-ended survey, semi-structured interviews, and ethnography. Significant empirical data from experienced engineers and scientists in a large engineering organization were obtained and integrated with theories from organization science and engineering. Qualitative analysis was used to obtain a holistic, contextualized understanding. The over-arching finding is that issues related to cognition, organization, and social interrelations mostly dominate interactions across disciplines. Engineering issues, such as the integration of hardware or physics-based models, are not as significant. For example, organization culture is an important underlying factor that guided researchers more toward individual sovereignty over cross-disciplinarity. The organization structure and the engineered system architecture also serve as constraints to the engineering work. Many differences in work practices were observed, including frequency and depth of interactions, definition or co-construction of requirements, clarity or creation of the system architecture, work group proximity, and cognitive challenges. Practitioners are often unaware of these differences resulting in confusion and incorrect assumptions

    Block copolymer electrolytes are promising materials for safe, long-lasting lithium batteries because of their favorable mechanical and ion transport properties. The morphology, phase behavior, and ionic conductivity of a block copolymer electrolyte, SEO mixed with LiTFSI was studied over a wide, previously unexplored salt concentration range using small angle X-ray scattering, differential scanning calorimetry and ac impedance spectroscopy, respectively. SEO exhibits a maximum in ionic conductivity at twice the salt concentration that PEO, the homopolymer analog of the ion-containing block, does. This finding is contrary to prior studies that examined a more limited range of salt concentrations. In SEO, the phase behavior of the PEO block and LiTFSI closely resembles the phase behavior of homopolymer PEO and LiTFSI. The grain size of the block copolymer morphology was found to decrease with increasing salt concentration, and the ionic conductivity of SEO correlates with decreasing grain size. Structural effects impact the ionic conductivity-salt concentration relationship in block copolymer electrolytes. SEO: polystyrene-block-poly(ethylene oxide); also PS-PEO LiTFSI: lithium bis(trifluoromethanesulfonyl imide

    In a world of shrinking habitats and increasing competition for natural resources, potentially dangerous predators bring the challenges of coexisting with wildlife sharply into focus. Through interdisciplinary collaboration among authors trained in the humanities, social sciences, and natural sciences, we reviewed current approaches to mitigating adverse human-predator encounters and devised a vision for future approaches to understanding and mitigating such encounters. Limitations to current approaches to mitigation include too much focus on negative impacts; oversimplified equating of levels of damage with levels of conflict; and unsuccessful technical fixes resulting from failure to engage locals, address hidden costs, or understand cultural (nonscientific) explanations of the causality of attacks. An emerging interdisciplinary literature suggests that to better frame and successfully mitigate negative human-predator relations conservation professionals need to consider dispensing with conflict as the dominant framework for thinking about human-predator encounters; work out what conflicts are really about (they may be human-human conflicts); unravel the historical contexts of particular conflicts; and explore different cultural ways of thinking about animals. The idea of cosmopolitan natures may help conservation professionals think more clearly about human-predator relations in both local and global context. These new perspectives for future research practice include a recommendation for focused interdisciplinary research and the use of new approaches, including human-animal geography, multispecies ethnography, and approaches from the environmental humanities notably environmental history. Managers should think carefully about how they engage with local cultural beliefs about wildlife, work with all parties to agree on what constitutes good evidence, develop processes and methods to mitigate conflicts, and decide how to monitor and evaluate these.

    2012-04-01

    A wide-range tunable level-keeper using vertical metal-oxide-semiconductor field-effect transistors (MOSFETs) is proposed for current-reuse analog systems. The design keys for widening tunable range of the operation are a two-path feed-back and a vertical MOSFET with back-bias-effect free. The proposed circuit with the vertical MOSFETs shows the 1.23-V tunable-range of the input level with the 2.4-V internal-supply voltage (VDD) in the simulation. This tunable-range of the proposed circuit is 4.7 times wider than that of the conventional. The achieved current efficiency of the proposed level-keeper is 66% at the 1.2-V output with the 2.4-V VDD. This efficiency of the proposed circuit is twice higher than that of the traditional voltage down converter.

    McCallin, Antoinette; Bamford, Anita

    2007-05-01

    The purpose of this study is to discuss how emotional intelligence affects interdisciplinary team effectiveness. Some findings from a larger study on interdisciplinary teamworking are discussed. Teams are often evaluated for complementary skill mix and expertise that are integrated for specialist service delivery. Interactional skills and emotional intelligence also affect team behaviour and performance. An effective team needs both emotional intelligence and expertise, including technical, clinical, social and interactional skills, so that teamwork becomes greater or lesser than the whole, depending on how well individuals work together. Team diversity, individuality and personality differences, and interprofessional safety are analysed to raise awareness for nurse managers of the complexity of interdisciplinary working relationships. If nursing input into interdisciplinary work is to be maximized, nurse managers might consider the role of emotional intelligence in influencing team effectiveness, the quality of client care, staff retention and job satisfaction.

    The mouse is essential for genetic studies of motor function in both normal and pathological states. Thus it is important to consider whether the structure of motor output from the mouse is in fact analogous to that recorded in other animals. There is a striking difference in the basic electrical properties of mouse motoneurons compared with those in rats, cats, and humans. The firing evoked by injected currents produces a unique frequency-current (F-I) function that emphasizes recruitment of motor units at their maximum force. These F-I functions, however, were measured in anesthetized preparations that lacked two key components of normal synaptic input: high levels of synaptic noise and neuromodulatory inputs. Recent studies suggest that the alterations in the F-I function due to these two components are essential for recreating firing behavior of motor units in human subjects. In this study we provide the first data on firing patterns of motor units in the awake mouse, focusing on steady output in quiet stance. The resulting firing patterns did not match the predictions from the mouse F-I behaviors but instead revealed rate modulation across a remarkably wide range (10-60 Hz). The low end of the firing range may be due to changes in the F-I relation induced by synaptic noise and neuromodulatory inputs. The high end of the range may indicate that, unlike other species, quiet standing in the mouse involves recruitment of relatively fast-twitch motor units.

  14. Performance on Interdisciplinary Topics in an Integrated Pharmacy Course

    Directory of Open Access Journals (Sweden)

    Joie Rowles

    2017-01-01

    Full Text Available Objectives: Many colleges and schools of Pharmacy combine interdisciplinary topics such as pathophysiology, pharmacology, medicinal chemistry and therapeutics into one integrated course. Our main aim for this study is to determine if students pass integrated courses and yet fail to pass interdisciplinary sections of those courses. Methods: Two representative integrated sequence courses were evaluated without any study-imposed intervention. Individual student examination scores (~140 students were evaluated for overall performance as well as for performance on the interdisciplinary topics of pathophysiology/pharmacology, medicinal chemistry, and therapeutics. The degree of difficulty of the examination questions, as well as the test item discrimination, were also measured. Results: There were students that passed the course but failed one, or more, of the interdisciplinary topics. Combining data from both courses, medicinal chemistry was the most frequently failed discipline (29 students, followed closely by pharmacology (22 students, and distantly by therapeutics (1 student. The examination questions for medicinal chemistry were not more difficult nor more discriminatory than the questions for the other disciplines. Conclusions: These data indicate that students pass integrated courses, but fail to pass interdisciplinary sections of those courses, especially the pharmaceutical sciences. It is not known if these results are consistent, nor what long-term adverse consequences may result. These results inform curricular and assessment aspects of the pharmacy academy as pertains to establishing the scientific foundation required by the CAPE 2013 Educational Outcomes.   Type: Original Research

    Hairy adhesive systems of microscopic setae with triangular flattened tips have evolved convergently in spiders, insects and arboreal lizards. The ventral sides of the feet and tails in chameleons are also covered with setae. However, chameleon setae feature strongly elongated narrow spatulae or fibrous tips. The friction enhancing function of these microstructures has so far only been demonstrated in contact with glass spheres. In the present study, the frictional properties of subdigital setae of Chamaeleo calyptratus were measured under normal forces in the physical range on plane substrates having different roughness. We showed that chameleon setae maximize friction on a wide range of substrate roughness. The highest friction was measured on asperities of 1 μm. However, our observations of the climbing ability of Ch. calyptratus on rods of different diameters revealed that also claws and grasping feet are additionally responsible for the force generation on various substrates during locomotion.

    We introduce a quasi two-dimensional (Q2D) methodology for assessing the swirling flow exiting the runner of hydraulic turbines at arbitrary operating points, within a wide operating range. The Q2D model does not need actual runner computations, and as a result it represents a surrogate runner model for a-priori assessment of the swirling flow ingested by the draft tube. The axial, radial and circumferential velocity components are computed on a conical section located immediately downstream the runner blades trailing edge, then used as inlet conditions for regular draft tube computations. The main advantage of our model is that it allows the determination of the draft tube losses within the intended turbine operating range in the early design stages of a new or refurbished runner, thus providing a robust and systematic methodology to meet the optimal requirements for the flow at the runner outlet

    Heavy ions detected in a planar silicon detector were identified by exploiting a recently proposed combination of the pulse-shape and the time-of-flight techniques. We were able to resolve charge numbers up to Z = 16 within a wide dynamic range of ∼ 1:5, and to identify even isotopes for the elements up to Magnesium. The simple scheme of signal processing is based on conventional electronics and cheap enough to be exploited in large multidetector arrays. (orig.)

    Interdisciplinary research and education programmes aim to produce groundbreaking research, often on socially relevant topics, and to produce experts with the skills to work across disciplines. However, there are many outstanding questions on the effectiveness of interdisciplinary programmes. Such as whether they produce novel and groundbreaking research, whether interdisciplinary graduates are leading to a more interdisciplinary culture of research and practice in academia and beyond, and whether an interdisciplinary approach can more effectively address issues of societal relevance than a mono-disciplinary approach. The Vienna Doctoral Programme on Water Resource Systems at Vienna University of Technology is currently in its eighth year and offers a valuable case study to contribute to understanding interdisciplinary research and education. Ten different research fields are covered by the Programme and because collaborative research takes place both between researchers from different research fields (cross-disciplinary research) and from researchers from the same research field (mono-disciplinary research) we are able to compare the impacts of each research type. We specifically explored three questions: i) whether cross-disciplinary research leads to more innovative scientific findings than mono-disciplinary research, ii) whether cross-disciplinary researchers develop professional skills that benefit their future careers, and iii) whether cross-disciplinary research produces findings of greater societal relevance than mono-disciplinary research. To conduct the evaluation we identified a variety of indicators. Journal impact factors (IF) and citation rates of ISI indexed publications were used to compare scientific innovativeness. Based on these indicators, our findings suggest that cross-disciplinary work is more innovative. The cross-disciplinary work is published in journals with a slightly higher impact factor (mean IF is 2.36) and receives slightly more

    The increasing shortage of (primary care) physicians in Germany is currently being discussed within and outside the profession. A national survey among general practice trainees aimed to explore their perspectives of vocational training (VT). After translation, cultural adaptation and web implementation of the questionnaire of the "Vasco da Gama Movement," the survey was conducted during 2009. Descriptive analyses were performed. Among 436 participants (mean age 36 years, 64% female, 49 months of VT) discipline-specific ("medically diverse discipline", "one-to-one care", and "holistic approach"), but also gender-related (females: "compatibility with family life", males: "autonomy and independence", and "opportunities to start their own practice") aspects were important to their choice of career. Despite the heavy workload job satisfaction, but not salary satisfaction, was generally high. Participants rated the following general conditions and content of VT as important: "structured rotations", "rotations in hospitals", "management skills", "working in a local care setting and in a multidisciplinary team" (all>88%). These results provide clues to improving VT in General Practice with respect to organisation and content including the consideration of gender-related living conditions. Furthermore, improvement and further development of VT programmes should ideally be part of an area-wide, interdisciplinary and intersectoral approach. Copyright © 2010. Published by Elsevier GmbH.

    that encourages dialogue between the disciplines and different expertise. The method tapped into a cost-effective way to obtain expertise from the European research network and collected a diverse set of research needs and ideas on the topic of bioenergy/ biodiversity. Through the method a collection of hundreds of ideas were analysed and synthesised, distilling into four interdisciplinary research plans. The method provided to the end-users of the research findings and other stakeholders a channel for participating in planning of the research. Although the resulting IDR framework was designed to deal with European- wide biodiversity issues, it is applicable for the planning of research in other contexts and on other scales. It can be applied, for example, in designing the research strategy for long-term socio-ecological research platforms (LTSER) or planning research in multidisciplinary research organisations. The framework presented in the report creates possibilities for communication between research and decisionmaking. By using the framework, relevant topics for discussion are brought up, emerging research needs are reacted to for elaboration into concrete research projects, and finally research findings are conveyed to support decision-making. To achieve this requires organised and open collaboration between research organisations and other stakeholders. The collaboration can be created and enhanced by the tested method presented in this report. (orig.)

  3. The perspective awareness model - Eliciting multiple perspectives to formulate high quality decisions

    2013-01-01

    A great deal of attention is given to the importance of communication in environmental remediation and radioactive waste management. However, very little attention is given to eliciting multiple perspectives so as to formulate high quality decisions. Plans that are based on a limited number of perspectives tend to be narrowly focused whereas those that are based on a wide variety of perspectives tend to be comprehensive, higher quality, and more apt to be put into application. In addition, existing methods of dialogue have built-in limitations in that they typically draw from the predominant thinking patterns which focus in some areas but ignore others. This can result in clarity but a lack of comprehensiveness. This paper presents a Perspective Awareness Model which helps groups such as partnering teams, interagency teams, steering committees, and working groups elicit a wide net of perspectives and viewpoints. The paper begins by describing five factors that makes cooperation among such groups challenging. Next, a Perspective Awareness Model that makes it possible to manage these five factors is presented. The two primary components of this model --- the eight 'Thinking Directions' and the 'Shared Documentation' --- are described in detail. Several examples are given to illustrate how the Perspective Awareness Model can be used to elicit multiple perspectives to formulate high quality decisions in the area of environmental remediation and radioactive waste management.

    Purified semiconducting single-walled carbon nanotubes (sc-SWCNTs) have been researched for optoelectronic applications due to their high absorption coefficient from the visible to even the near-infrared (NIR) region. Nevertheless, the insufficient electrical characteristics and incompatibility with conventional CMOS processing have limited their wide utilization in this emerging field. Here, we demonstrate highly detective and wide spectral/dynamic range phototransistors incorporating floated heterojunction active layers which are composed of low-temperature sol-gel processed n-type amorphous indium gallium zinc oxide (a-IGZO) stacked with a purified p-type sc-SWCNT layer. To achieve a high and broad spectral/dynamic range photo-response of the heterogeneous transistors, photochemically functionalized sc-SWCNT layers were carefully implemented onto the a-IGZO channel area with a floating p-n heterojunction active layer, resulting in the suppression of parasitic charge leakage and good bias driven opto-electrical properties. The highest photosensitivity (R) of 9.6 × 10 2 A W -1 and a photodetectivity (D*) of 4 × 10 14 Jones along with a dynamic range of 100-180 dB were achieved for our phototransistor in the spectral range of 400-780 nm including continuous and minimal frequency independent behaviors. More importantly, to demonstrate the diverse application of the ultra-flexible hybrid photosensor platform as skin compatible electronics, the sc-SWCNT/a-IGZO phototransistors were fabricated on an ultra-thin (∼1 μm) polyimide film along with a severe static and dynamic electro-mechanical test. The skin-like phototransistors showed excellent mechanical stability such as sustainable good electrical performance and high photosensitivity in a wide dynamic range without any visible cracks or damage and little noise interference after being rolled-up on the 150 μm-thick optical fiber as well as more than 1000 times cycling.

    Nordic Energy Perspectives is an interdisciplinary energy research project which, from a holistic perspective, analyses and creates new insights into the consequences for energy markets and energy systems of the goals and instruments of energy policy in the light of new conditions. The project's aim is to provide better bases for decisions on energy and environmental policy at both national and international levels. It is intended to contribute to constructive dialogue between researchers, politicians, authorities and actors on the energy markets. A first phase of the project has been carried out during Apr 2005 - Sep 2006. This report summarises the most important results. Around fifteen current research issues have been analysed. Some of these issues have been analysed in detail, while others have been studied more generally. This means that we can present a comprehensive flora of results in a number of areas, whereas in regard to other questions the analysis is less deep and the conclusions are not as firmly grounded. We have nonetheless chosen to present the entire range of results in this final report. An objective of Nordic Energy Perspectives has been to create a forum for fact-based discussion and dialogue between decision-makers and other energy actors from different disciplines and different countries. Today this forum is fully active. We are very eager that the forum should survive and that the discussion should continue concerning the themes treated by Nordic Energy Perspectives. Hence, for each of the chapters 1-17 below, we identify the researchers whom the reader can contact for further dialogue. The ten perspectives, which are based on contributions from the whole research group, have the following headlines: Costly early learnings from the first year of EU ETS: Unforeseen price levels hit industries hard; Market based support schemes - do they really work as intended; New decade in the Nordic energy markets; Reduced CO 2 emissions and more

    One of the greatest challenges for conserving grassland, prairie scrub, and shrub-steppe ecosystems is maintaining prairie dog populations across the landscape. Of the four species of prairie dogs found in the United States, the Utah prairie dog (Cynomys parvidens) is listed under the Endangered Species Act (ESA) as threatened, the Gunnison's prairie dog (C. gunnisoni) is a candidate for listing in a portion of its range, and the black-tailed prairie dog (C. ludovicianus) and white-tailed prairie dog (C. leucurus) have each been petitioned for listing at least once in recent history. Although the U.S. Fish and Wildlife Service (USFWS) determined listing is not warranted for either the black-tailed prairie dog or white-tailed prairie dog, the petitions and associated reviews demonstrated the need for the States to monitor and manage for self-sustaining populations. In response to these findings, a multi-State conservation effort was initiated for the nonlisted species which included the following proposed actions: (1) completing an assessment of each prairie dog species in each State, (2) developing a range-wide monitoring protocol for each species using a statistically valid sampling procedure that would allow comparable analyses across States, and (3) monitoring prairie dog status every 3-5 years depending upon the species. To date, each State has completed an assessment and currently is monitoring prairie dog status; however, for some species, the inconsistency in survey methodology has made it difficult to compare data year-to-year or State-to-State. At the Prairie Dog Conservation Team meeting held in November 2008, there was discussion regarding the use of different methods to survey prairie dogs. A recommendation from this meeting was to convene a panel in a workshop-type forum and have the panel review the different methods being used and provide recommendations for range-wide monitoring protocols for each species of prairie dog. Consequently, the Western

    Biomedical and health informatics (BHI) is a rapidly growing domain that relies on the active collaboration with diverse disciplines and professions. Educational initiatives in BHI need to prepare students with skills and competencies that will allow them to function within and even facilitate interdisciplinary teams (IDT). This paper describes an interdisciplinary educational approach introduced into a BHI graduate curriculum that aims to prepare informatics researchers to lead IDT research. A case study of the "gerontechnology" research track is presented which highlights how the curriculum fosters collaboration with and understanding of the disciplines of Nursing, Engineering, Computer Science, and Health Administration. Gerontechnology is a new interdisciplinary field that focuses on the use of technology to support aging. Its aim is to explore innovative ways to use information technology and develop systems that support independency and increase quality of life for senior citizens. As a result of a large research group that explores "smart home" technologies and the use of information technology, we integrated this new domain into the curriculum providing a platform for computer scientists, engineers, nurses and physicians to explore challenges and opportunities with our informatics students and faculty. The interdisciplinary educational model provides an opportunity for health informatics students to acquire the skills for communication and collaboration with other disciplines. Numerous graduate and postgraduate students have already participated in this initiative. The evaluation model of this approach is presented. Interdisciplinary educational models are required for health informatics graduate education. Such models need to be innovative and reflect the needs and trends in the domains of health care and information technology.

  19. Population Genomics and the Statistical Values of Race:An Interdisciplinary Perspective on the Biological Classification of Human Populations and Implications for Clinical Genetic Epidemiological Research

    Full Text Available The biological status and biomedical significance of the concept of race as applied to humans continue to be contentious issues despite the use of advanced statistical and clustering methods to determine continental ancestry. It is thus imperative for researchers to understand the limitations as well as potential uses of the concept of race in biology and biomedicine. This paper deals with the theoretical assumptions behind cluster analysis in human population genomics. Adopting an interdisciplinary approach, it demonstrates that the hypothesis that attributes the clustering of human populations to frictional effects of landform barriers at continental boundaries is empirically incoherent. It then contrasts the scientific status of the cluster and cline constructs in human population genomics, and shows how cluster may be instrumentally produced. It also shows how statistical values of race vindicate Darwin’s argument that race is evolutionarily meaningless. Finally, the paper explains why, due to spatiotemporal parameters, evolutionary forces and socio-cultural factors influencing population structure, continental ancestry may be pragmatically relevant to global and public health genomics. Overall, this work demonstrates that, from a biological systematic and evolutionary taxonomical perspective, human races/continental groups or clusters have no natural meaning or objective biological reality. In fact, the utility of racial categorizations in research and in clinics can be explained by spatiotemporal parameters, socio-cultural factors and evolutionary forces affecting disease causation and treatment response.

    In this study, we have demonstrated the fabrication of a microbeam array (MBA) with various thicknesses and investigated the suitability it for an acoustic sensor with wide-range frequency selectivity. For this, an MBA composed of 64 beams, with thicknesses varying from 2.99–142 µm, was fabricated by using single gray-scale lithography and a thick negative photoresist. The vibration of the beams in air was measured using a laser Doppler vibrometer; the resonant frequencies of the beams were measured to be from 11.5 to 290 kHz. Lastly, the frequency range of the MBA with non-uniform thickness was 10.9 times that of the MBA with uniform thickness. (paper)

    Franta, Daniel; Nečas, David; Giglia, Angelo; Franta, Pavel; Ohlídal, Ivan

    2017-11-01

    Optical characterization of magnesium fluoride thin films is performed in a wide spectral range from far infrared to extreme ultraviolet (0.01-45 eV) utilizing the universal dispersion model. Two film defects, i.e. random roughness of the upper boundaries and defect transition layer at lower boundary are taken into account. An extension of universal dispersion model consisting in expressing the excitonic contributions as linear combinations of Gaussian and truncated Lorentzian terms is introduced. The spectral dependencies of the optical constants are presented in a graphical form and by the complete set of dispersion parameters that allows generating tabulated optical constants with required range and step using a simple utility in the newAD2 software package.

    In the wake of the 2010 tsunami that hit Chile, a major public effort to promote interdisciplinary disaster reseach was undertaken by the Comisión Nacional de Investigación Científica y Tecnológica (Conicyt) allocating funds to create the Center for Integrated Research on Natural Risks Management (CIGIDEN). This effort has been key in promoting associativity between national and international research teams in order to transform the frequent occurrence of extreme events that affect Chile into an opportunity for interdisciplinary research. In this presentation we will summarize some of the fundamental research findings regarding tsunami forecasting, alerting, and evacuation processes based on interdisciplinary field work campaigns and modeling efforts conducted in the wake of the three most recent destructive events that hit Chile in 2010, 2014, and 2015. One of the main results that we shall emphatize from these findings, is that while research and operational efforts to model and forecast tsunamis are important, technological positivisms should not undermine educational efforts that have proved to be effective in reducing casualties due to tsunamis in the near field. Indeed, in recent events that hit Chile, first tsunami waves reached the adjacent generation zones in time scales comparable with the required time for data gathering and modeling even for the most sophisticated early warning tsunami algorithms currently available. The latter emphasizes self-evacuation from coastal areas, while forecasting and monitoring tsunami hazards remain very important for alerting more distant areas, and are essential for alert cancelling especially when shelf and embayment resonance, and edge wave propagation may produce destructive late tsunami arrivals several hours after the nucleation of the earthquake. By combining some of the recent evidence we have gathered in Chile on seismic source uncertainities (both epistemic and aleatoric), tsunami hydrodynamics, the response

    In the genomic age, the challenges presented by various inherited conditions present a compelling argument for an interdisciplinary model of care. Cardiac arrhythmias with a genetic basis, such as long QT syndrome, require clinicians with expertise in many specialties to address the complex genetic, psychological, ethical and medical issues involved in treatment. The Montefiore-Einstein Center for CardioGenetics has been established to provide personalized, interdisciplinary care for families with a history of sudden cardiac death or an acute cardiac event. Four vignettes of patient care are presented to illustrate the unique capacity of an interdisciplinary model to address genetic, psychological, ethical and medical issues. Because interdisciplinary clinics facilitate collaboration among multiple specialties, they allow for individualized, comprehensive care to be delivered to families who experience complex inherited medical conditions. As the genetic basis of many complex conditions is discovered, the advantages of an interdisciplinary approach for delivering personalized medicine will become more evident.

    2017-04-01

    Full Text Available The environmental pollution of 2,4,6-tribromophenol (TBP has attracted attention. Based on an urgent need for the better provision of clean water, in situ determination of TBP is of great importance. Here, a facile and effective approach for detecting TBP is developed, based on coupling molecular imprinting technique with electrodeposition of chitosan (CS on the gold electrode. The TBP imprinting CS film was fabricated by using CS as functional material and TBP as template molecule. The experiments show that the morphologies and electrochemical properties of the imprinted film sensor was different from non-imprinted film electrode. The current of the imprinted film was linearly proportional to the TBP concentration, with a wide linear range of 1.0 × 10−7 mol•L−1 to 1.0 × 10−3 mol•L−1. By selecting drop-coating method as a reference for controlled trials with the same functional material, the results illustrated that the electrodeposition enjoyed a widely linear range advantage.

    This paper investigates the effect of grid impedance variation on harmonic resonant current controllers for gridconnected voltage source converters by means of impedance-based analysis. It reveals that the negative harmonic resistances tend to be derived from harmonic resonant controllers...... in the closed-loop output admittance of converter. Such negative resistances may interact with the grid impedance resulting in steady state error or unstable harmonic compensation. To deal with this problem, a design guideline for harmonic resonant controllers under a wide range of grid impedance is proposed...

    The study aimed to understand the health of student experiences to participate in interdisciplinary discussions in bioethics and know the contributions of interdisciplinary methodological resource for the teaching-learning process at graduation. Descriptive study of qualitative approach in a public higher education institution of Divinópolis, Minas Gerais, Brazil. Three categories of analysis were identified: ''active methodologies in the training of a professional critic,'' ''interdisciplinary debate as facilitator reflection of bioethics'' and ''feelings and attitudes caused by the interdisciplinary debate.'' Discussion. There was a lack of approach of bioethical contents in the health curriculum, and the adoption of active methodologies provides a better reflection in bioethics, but that requires changing paradigms of teachers and educational institutions.

  11. Lingua-Pedagogy as the Interdisciplinary Research Problem

    Directory of Open Access Journals (Sweden)

    A. N. Yakovleva

    2012-01-01

    Full Text Available  The paper is devoted to lingua-pedagogy – one of the modern branches of pedagogy dealing with personal socialization in the process of foreign language learning. This interdisciplinary field of knowledge is related to linguistics, pedagogic psychology, development psychology and acmeology. Lingua-pedagogy undergoes the formation process; therefore, there still are a number of open questions concerning its place among the other sciences, and the final definitions of the main concepts and terms. The author recommends the systematic approach to developing the theoretical foundation of lingua- pedagogy. The paper outlines the subject and aims of the lingua-pedagogic research, its content and affecting means. The system in question is poly- functional, its main functions being the integral pedagogic effect in foreign language teaching, stimulating self-dependent learning, and arranging the in- tercultural integration. The linguistic faculties at universities can be taken as the key elements of the lingua-pedagogic system – the development centers, nurturing the value-oriented respectful attitude to the native and foreign cul- ture, providing intercultural competence acquisition, and training pedagogic staff capable of fulfilling the poly-cultural development tasks. Identification of the conformities of intercultural socialization makes it possible to organize the system of pedagogic facilitation for students learning foreign languages; and develop the perspective methods and technologies of language competence acquisition and consolidation.

    2014-01-01

    Creare Incorporated and NASA Goddard Space Flight Center developed and space qualified two wide range pumps (WRPs) that were included in the Sample Analysis at Mars (SAM) instrument. This instrument was subsequently integrated into the Mars Science Laboratory (MSL) "Curiosity Rover," launched aboard an Atlas V rocket in 2011, and landed on August 6, 2012, in the Gale Crater on Mars. The pumps have now operated for more than 18 months in the Gale Crater and have been evacuating the key components of the SAM instrument: a quadrupole mass spectrometer, a tunable laser spectrometer, and six gas chromatograph columns. In this paper, we describe the main design challenges and the ways in which they were solved. This includes the custom design of a miniaturized, high-speed motor to drive the turbo drag pump rotor, analysis of rotor dynamics for super critical operation, and bearing/lubricant design/selection.

    CERN Document Server

    Guido Venturini, G G; Dehning, B; Kayal, M

    2012-01-01

    An Application Specific Integrated Circuit (ASIC) has been designed and fabricated to provide a compact solution to digitize current signals from ionization chambers and diamond detectors, employed as beam loss monitors at CERN and several other high energy physics facilities. The circuit topology has been devised to accept positive and negative currents, to have a wide dynamic range (above 120 dB), withstand radiation levels over 10 Mrad and offer different modes of operation, covering a broad range of applications. Furthermore, an internal conversion reference is employed in the digitization, to provide an accurate absolute measurement. This paper discusses the detailed characterization of the first prototype: linearity, radiation tolerance and temperature dependence of the conversion, as well as implications and system-level considerations regarding its use for beam instrumentation applications in a high energy physics facility.

    Kremens, R.; Dickinson, M. B.; Hardy, C.; Skowronski, N.; Ellicott, E. A.; Schroeder, W.

    2016-12-01

    We have developed a wide dynamic range (24-bit) data acquisition system for collection of radiant flux density (FRFD) data from wildland fires. The data collection subsystem was designed as an Arduino `shield' and incorporates a 24-bit analog-to-digital converter, precision voltage reference, real time clock, microSD card interface, audible annuciator and interface for various digital communication interfaces (RS232, I2C, SPI, etc.). The complete radiometer system consists of our custom-designed `shield', a commercially available Arduino MEGA computer circuit board and a thermopile sensor -amplifier daughter board. Software design and development is greatly assisted by the availability of a library of public-domain, user-implemented software. The daughter board houses a 5-band radiometer using thermopiles designed for this experiment (Dexter Research Corp., Dexter, MI) to allow determination of the total FRFD from the fire (using a wide band thermopile with a KRS-5 window, 0.1 - 30 um), the FRFD as would be received by an orbital asset like MODIS (3.95 um center wavelength (CWL) and 10.95 CWL, corresponding to MODIS bands 21/22 and 31, respectively) and wider bandpass (0.1-5.5 um and 8-14 um) corresponding to the FRFD recorded by `MWIR' and `LWIR' imaging systems. We required a very wide dynamic range system in order to be able to record the flux density from `cold' ground before the fire, through the `hot' flaming combustion stage, to the `cool' phase after passage of the fire front. The recording dynamic range required (with reasonable resolution at the lowest temperatures) is on the order of 106, which is not currently available in commercial instrumentation at a price point, size or feature set that is suitable for wildland fire investigations. The entire unit, along with rechargeable battery power supply is housed in a fireproof aluminum chassis box, which is then mounted on a mast at a height of 5 - 7 m above the fireground floor. We will report initial

  19. A Comparison of the Social-Adaptive Perspective and Functionalist Perspective on Guilt and Shame

    Directory of Open Access Journals (Sweden)

    Heidi L. Dempsey

    2017-12-01

    Full Text Available Within the field of guilt and shame two competing perspectives have been advanced. The first, the social-adaptive perspective, proposes that guilt is an inherently adaptive emotion and shame is an inherently maladaptive emotion. Thus, those interested in moral character development and psychopathology should work to increase an individual’s guilt-proneness and decrease an individual’s shame-proneness. The functionalist perspective, in contrast, argues that both guilt and shame can serve a person adaptively or maladaptively—depending on the situational appropriateness, duration, intensity, and so forth. This paper reviews the research conducted supporting both positions; critiques some issues with the most widely used guilt- and shame-proneness measure in the social-adaptive research (the TOSCA and discusses the differences in results found when assessing guilt and shame at the state versus trait level. The conclusion drawn is that although there is broad support for the functionalist perspective across a wide variety of state and trait guilt/shame studies, the functionalist perspective does not yet have the wealth of data supporting it that has been generated by the social-adaptive perspective using the TOSCA. Thus, before a dominant perspective can be identified, researchers need to (1 do more research assessing how the social-adaptive perspective compares to the functionalist perspective at the state level and (2 do more trait research within the functionalist perspective to compare functionalist guilt- and shame-proneness measures with the TOSCA.

    1984-01-01

    The present invention contemplates providing a sample system for effluent from a nuclear process wherein the effluent in a first mode passes through a sample chamber whose noble gases are quantitatively detected. The sample of the first mode is continued until the detector count rate reaches a predetermined maximum. The detector establishes a control signal which is applied to terminate the first mode effluent flow to the chamber, evacuate the chamber to a predetermined value of vacuum and connect the effluent into the sample chamber with a predetermined mode of flow rate different from the rate of the first mode to establish a sample concentration in the chamber within the range of the detector. A subsequent predetermined minimum rate will generate a signal to reconnect the sample chamber to the first mode connection and thereby cycle the system back to its first mode of operation

  3. Collaborative Research on Sustainability: Myths and Conundrums of Interdisciplinary Departments

    Directory of Open Access Journals (Sweden)

    Kate Sherren

    2009-01-01

    Full Text Available Establishing interdisciplinary academic departments has been a common response to the challenge of addressing complex problems. However, the assumptions that guide the formation of such departments are rarely questioned. Additionally, the designers and managers of interdisciplinary academic departments in any field of endeavour struggle to set an organisational climate appropriate to the diversity of their members. This article presents a preliminary analysis of collaborative dynamics within two interdisciplinary university departments in Australia focused on sustainability. Social network diagrams and metrics of coauthorship and cosupervision are analysed qualitatively. A “vicarious interdisciplinarity” was identified among key academics working narrowly in order to earn the resources that allow them to support others working interdisciplinarily. Those supported in this way appear to benefit from the esteem and nonredundant collaborative connections their mentors provide via this strategy, but they experience uncertainty about their own career opportunities in similar settings. This article thus unearths a conundrum of succession for interdisciplinary academic environments, and suggests that simple colocation of diverse academic stars is an inadequate strategy to achieve effective intradepartmental collaboration.

    The ability of investigators of an interdisciplinary science project to properly manage the data that are collected during the experiment is critical to the effective conduct of science. When the project becomes large, possibly including several scenes of large-format remotely sensed imagery shared by many investigators requiring several services, the data management effort can involve extensive staff and computerized data inventories. The OTTER (Oregon Transect Ecosystem Research) project was supported by the PLDS (Pilot Land Data System) with several data management services, such as data inventory, certification, and publication. After a brief description of these services, experiences in providing them are compared with earlier data management efforts and some conclusions regarding data management in support of interdisciplinary science are discussed. In addition to providing these services, a major goal of this data management capability was to adopt characteristics of a pro-active attitude, such as flexibility and responsiveness, believed to be crucial for the effective conduct of active, interdisciplinary science. These are also itemized and compared with previous data management support activities. Identifying and improving these services and characteristics can lead to the design and implementation of optimal data management support capabilities, which can result in higher quality science and data products from future interdisciplinary field experiments.

    Motor functional neurologic disorders (FND)-previously termed "hysteria" and later "conversion disorder"-are exceedingly common and frequently encountered in the acute hospital setting. Despite their high prevalence, patients with motor FND can be challenging to diagnose accurately and manage effectively. To date, there is limited guidance on the inpatient approach to the neuropsychiatric evaluation of patients with functional (psychogenic) neurologic symptoms. The authors outline an inpatient multidisciplinary approach, involving neurology, psychiatry, and physical therapy, for the assessment and acute inpatient management of motor FND. A vignette of a patient with motor FND is presented followed by a discussion of general assessment principles. Thereafter, a detailed description of the neurologic and psychiatric assessments is outlined. Delivery of a "rule-in" diagnosis is emphasized and specific guidance for what can be accomplished postdiagnosis in the hospital is suggested. We encourage an interdisciplinary approach beginning at the early stages of the diagnostic assessment once an individual is suspected of having motor FND. Practical suggestions for the inpatient assessment of motor FND are presented. It is also important to individualize the diagnostic assessment. Future research should be conducted to test best practices for motor FND management in the acute inpatient hospital setting. Copyright © 2018 Academy of Consultation-Liaison Psychiatry.

The detector is used in current mode, and front-end electronics based on a logarithmic amplifier are used in order to have a measurement capability ranging over many orders of magnitude. The system has been calibrated at the Polytechnic of Milan, CESNEF, with an AmBe neutron source, and has been tested in a pulsed field at the PUNITA facility at JRC, Ispra. The detector has achieved a dynamic range of over 6 orders of magnitude, being able to measure single neutron pulses and showing saturation-free response for a reaction rate up to 10{sup 6} s{sup -1}. It has also proved effective in measuring the PUNITA facility pulse integral fluence.

    Borrego, Maura; Creamer, Elizabeth G.

    This work directly compares three explanations for differences in experiences of interdisciplinary research collaborators using a sample of 347 academics from 144 different research intensive and extensive universities in the United States who were awarded funding from the same directorate of the National Science Foundation. The findings provide a much more positive view of interdisciplinary collaboration than is routinely found in the literature. Despite varied disciplinary backgrounds, members of the sample are extremely satisfied with their experiences with interdisciplinary collaboration and have much more in common than they differ in their attitudes and experiences, including how they meet collaborators, the difficulties they have encountered, their approach to the division of labor, and their interest in collaboration as a venue for learning. Findings dispute the stereotype that the relational element of collaboration is significantly more salient for women than it is for men.

    In this study, we propose a highly sensitive multichannel pH sensor that is based on an optical-fiber pulse width modulation (PWM) technique. According to the optical-fiber PWM method, the received sensing signal?s pulse width changes when the optical-fiber pH sensing-element of the array comes into contact with pH buffer solutions. The proposed optical-fiber PWM pH-sensing system offers a linear sensing response over a wide range of pH values from 2 to 12, with a high pH-sensing ability. The...

    Mentoring is critical for academic success. As science transitions to a team science model, team mentoring may have advantages. The goal of this study was to understand the process, benefits, and challenges of team mentoring relating to career development and research. A national survey was conducted of Building Interdisciplinary Research Careers in Women's Health (BIRCWH) program directors-current and former scholars from 27 active National Institutes of Health (NIH)-funded BIRCWH NIH K12 programs-to characterize and understand the value and challenges of the team approach to mentoring. Quantitative data were analyzed descriptively, and qualitative data were analyzed thematically. Responses were received from 25/27 (93%) program directors, 78/108 (72%) current scholars, and 91/162 (56%) former scholars. Scholars reported that team mentoring was beneficial to their career development (152/169; 90%) and research (148/169; 88%). Reported advantages included a diversity of opinions, expanded networking, development of stronger study designs, and modeling of different career paths. Challenges included scheduling and managing conflicting opinions. Advice by directors offered to junior faculty entering team mentoring included the following: not to be intimidated by senior mentors, be willing to navigate conflicting advice, be proactive about scheduling and guiding discussions, have an open mind to different approaches, be explicit about expectations and mentors' roles (including importance of having a primary mentor to help navigate discussions), and meet in person as a team. These findings suggest that interdisciplinary/interprofessional team mentoring has many important advantages, but that skills are required to optimally utilize multiple perspectives.

    Over the past thirteen years the Anthropological Center for Training and Research on Global Environmental Change (ACT) at Indiana University has pioneered the use of anthropological and environmental research approaches to address issues of land use change, and population-environment interaction, particularly in the Amazon. Our research and training objectives focus on how particular local populations manage resources and how those activities may be studied by integrating time-tested ethnographic methods, survey instruments, ecological field studies, and the spatial and temporal perspectives of remote sensing and Geographical Information Systems. The globalization of the environment crisis bears the risk of the research and training at universities being purely global or large scale in nature. This would fail to take into account the highly variable local causes of human activities or to discover sustainable solutions to the use, conservation, and restoration of human ecosystems. Our approach combines institutional and international collaboration, formal and hands-on laboratory and field activities developed within an interdisciplinary environment, but based on the strength of disciplinary programs. Over the past years, we have particularly emphasized collaboration between American and Brazilian scholars and students and intense work with local farmers and communities both during data collection and field research, as well as in returning data and results using different formats. In this paper, we address our experience, the challenges and advantages of theoretical and methodological development for students approaching interdisciplinary problems, innovations in linking levels of analysis, and new opportunities for international and collaborative training and research on human-environment interaction.

  14. Enhancing Decision Support For Climate Adaptation At Sub-Regional To Local Scales Through Collaborative And Interdisciplinary Global Change Research And Application

    The science needed to inform society's response to global environmental change is increasingly demanded at sub-regional to local scales, placing a greater burden on the science community to respond to a wide variety of information needs. Oftentimes, communication barriers prevent even the basic articulation of information needs between the user and science research communities, and furthermore there is frequently a mismatch between available scientific talent within a sub region and the scientific resources demanded to respond appropriately to user inquiries. As a result, innovative approaches to the delivery of scientific information in response to user interests and needs at sub-regional to local levels is required. Here, the authors highlight lessons of three examples of delivering usable scientific information within a mountain watershed on questions relating to 1) local biomass energy production; 2) stream and forest health; and 3) watershed scale climate impacts assessment. We report that common elements to the success of these efforts include a) building relationships with both a broad range of disciplines within the science community as well as a wide range of stakeholder groups locally, b) collecting and translating existing monitoring data and filling monitoring gaps, c) gathering interdisciplinary teams to help answer difficult local scale questions not previously treated in literature, and d) communicating results through mechanisms such as stakeholder collaboratives, community forums, and innovative education and outreach products. We find that these components help communities at local to sub-regional scales identify vulnerabilities and adapative strategies.

    Drawing on the authors' involvement in a European Union Erasmus project, this paper explores a new holistic approach to climate change education which uses as a source of active/social learning and knowledge construction the diversity of different disciplinary and sectoral approaches. We further argue for a corresponding pedagogy based on developing transboundary competences where the communicative engagement across space and time, and between diverse perspectives and standpoints, is ICT-enabled. Meeting these challenges is a normative goal, not only for this expanded interdisciplinary approach to climate change education, but also for a global resolution of the climate change issue itself.

    More than approximately 50 years of operations, storage, and disposal of wastes generated by the three facilities on the Oak Ridge Reservation (ORR) (the Oak Ridge K-25 Site, Oak Ridge National Laboratory, and the Oak Ridge Y-12 Plant) has resulted in a mosaic of uncontaminated property and lands that are contaminated to varying degrees. This contaminated property includes source areas and the terrestrial and aquatic habitats down gradient from these source areas. Although the integrator OUs generally contain considerable habitat for biota, the source OUs provide little or no suitable habitat. Historically, ecological risk assessment at Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) sites has focused on species that may be definitively associated with a contaminated area or source OU. Endpoints considered in source OUs include plants, soil/litter invertebrates and processes, aquatic biota found in on-OU sediments and surface waters, and small herbivorous, omnivorous, and vermivorous (i.e., feeding on ground, litter, or soil invertebrates) wildlife. All of these endpoints have limited spatial distributions or home ranges such that numerous individuals or a distinct population can be expected to reside within the boundaries of the source OU. Most analyses are not adequate for large sites with multiple, spatially separated contaminated areas such as the ORR that provide habitat for wide-ranging wildlife species. This report is a preliminary response to a plan for assessing risks to wide-ranging species.

    Solar tri-diurnal variations of cosmic rays have been analyzed in a wide range of rigidity, using data from neutron monitors, and the surface and underground muon telescopes for the period 1978-1983. The rigidity spectrum of the anisotropy in space is assumed to be of power-exponential type as (P/gamma P sub o) to the gamma exp (gamma-P/P sub o). By means of the best-fit method between the observed and the expected variations, it is obtained that the spectrum has a peak at P (=gamma P sub o) approx = 90 GV, where gamma=approx 3.0 and P sub o approx. 30 GV. The phase in space of the tri-diurnal variation is also obtained as 7.0 hr (15 hr and 23 hr LT), which is quite different from that of approx. 1 hr. arising from the axisymmetric distribution of cosmic rays with respect to the IMF.

    The integration of genetic information with ecological and phenotypic data constitutes an effective approach to gain insight into the mechanisms determining interpopulation variability and the evolutionary processes underlying local adaptation and incipient speciation. Here, we use the Pyrenean Morales grasshopper (Chorthippus saulcyi moralesi) as study system to (i) analyse the relative role of genetic drift and selection in range-wide patterns of phenotypic differentiation and (ii) identify the potential selective agents (environment, elevation) responsible for variation. We also test the hypothesis that (iii) the development of dispersal-related traits is associated with different parameters related to population persistence/turnover, including habitat suitability stability over the last 120 000 years, distance to the species distribution core and population genetic variability. Our results indicate that selection shaped phenotypic differentiation across all the studied morphological traits (body size, forewing length and shape). Subsequent analyses revealed that among-population differentiation in forewing length was significantly explained by a temperature gradient, suggesting an adaptive response to thermoregulation or flight performance under contrasting temperature regimes. We found support for our hypothesis predicting a positive association between the distance to the species distribution core and the development of dispersal-related morphology, which suggests an increased dispersal capability in populations located at range edges that, in turn, exhibit lower levels of genetic variability. Overall, our results indicate that range-wide patterns of phenotypic variation are partially explained by adaptation in response to local environmental conditions and differences in habitat persistence between core and peripheral populations. © 2016 European Society For Evolutionary Biology.
