    The effects of ionising and non-ionising radiation on rodent tumours and normal tissue were studied in terms of cellular repair and the relevant biochemical and biophysical changes following radiation. Rodent tumours investigated in vivo were the CaNT adenocarcinoma and a chemically induced transplantable rhabdomyosarcoma. Radiations used were 100KVp of X-Rays, neutron beams, various magnetic fields, and microwave radiation of 2450MHz. The biochemical parameters measured were, inter alia, levels of adenosine-5'-triphoshate (ATP) and the specific activity of hexokinase (HK). Metabolic changes in ATP levels and the activity of HK were observed in tumour and normal tissues following ionising and non-ionising radiation in normoxia and hypoxia. The observation that the effect of radiation and chemotherapeutic treatment of some tumours may be size dependent can possibly now be explained by the variation of ATP content with tumour size. The enhanced tumour HK specific activity implies increased metabolism, possibly a consequence of cellular requirements to maintain homeostasis during repair processes. Other research projects of the Research Institute for Medical Biophysics involved, inter alia, gastroesophageal scintigraphies to evaluate the results of new forms of therapy. 1 ill

    The message of this book is that biophysics is the science of physical principles underlying the "phenomenon life" on all levels of organization. Rather than teaching "physics for biologists" or "physical methods applied to biology", it regards its subject as a defined discipline with its own network of ideas and approaches. The book starts by explaining molecular structures of biological systems, various kinds of atomic, molecular and ionic interactions, movements, energy transfer, self organization of supramolecular structures and dynamic properties of biological membranes. It then goes on to introduce the biological organism as a non-equilibrium system, before treating thermodynamic concepts of osmotic and electrolyte equilibria as well as currents and potential profiles. It continues with topics of environmental biophysics and such medical aspects as the influence of electromagnetic fields or radiation on living systems and the biophysics of hearing and noice protection. The book concludes with a discussi...

  5. An ethnographic study: Becoming a physics expert in a biophysics research group

    Science.gov (United States)

    Rodriguez, Idaykis

    Expertise in physics has been traditionally studied in cognitive science, where physics expertise is understood through the difference between novice and expert problem solving skills. The cognitive perspective of physics experts only create a partial model of physics expertise and does not take into account the development of physics experts in the natural context of research. This dissertation takes a social and cultural perspective of learning through apprenticeship to model the development of physics expertise of physics graduate students in a research group. I use a qualitative methodological approach of an ethnographic case study to observe and video record the common practices of graduate students in their biophysics weekly research group meetings. I recorded notes on observations and conduct interviews with all participants of the biophysics research group for a period of eight months. I apply the theoretical framework of Communities of Practice to distinguish the cultural norms of the group that cultivate physics expert practices. Results indicate that physics expertise is specific to a topic or subfield and it is established through effectively publishing research in the larger biophysics research community. The participant biophysics research group follows a learning trajectory for its students to contribute to research and learn to communicate their research in the larger biophysics community. In this learning trajectory students develop expert member competencies to learn to communicate their research and to learn the standards and trends of research in the larger research community. Findings from this dissertation expand the model of physics expertise beyond the cognitive realm and add the social and cultural nature of physics expertise development. This research also addresses ways to increase physics graduate student success towards their PhD. and decrease the 48% attrition rate of physics graduate students. Cultivating effective research

    Research is reported on magnetic resonance spectroscopy of biological molecules, development of clinical applications of stable isotopes, circadian cybernetics, and X-ray crystallography of immunoglobulins. Biological processes occur in fluid media, and ultimately our knowledge of their mechanisms requires detailed information for chemical and molecular structural properties in biological fluids. Magnetic resonance spectroscopy has unique advantages over other approaches in this area that are being exploited in studies currently underway in the group. The program continues to develop along three interrelated lines, measurement and analysis of high resolution spectra for biological molecules (especially nucleic acid constituents and drugs), synthesis of selectively labeled nucleic acid fragments essential for complete spectral assignments, and computation of conformational properties from NMR parameters. This coordinated approach enabled the first complete conformation analysis for a dinucleoside monophosphate, ApA, in aqueous solution. It was found that the conformation is actually a time-average of right helical, loop, and extended conformations, the interchange being extremely rapid on an NMR time scale. Spectral analyses were also completed for all possible ribonucleotide dimers, the assignments again relying heavily on synthesis of appropriate deuterated counterparts. Studies of conformational flexibility in nucleic acid fragments showed that changes in hydrogen ion concentration and temperature produce correlated conformational changes specific for each nucleotidyl unit. Studies were also initiated in three new projects dealing with the effect of hapten binding on antibody structure, counter ion influence on nucleic acid free radicals, and membrane differences between normal and sickled erythrocytes

    Rodriguez, Idaykis; Goertzen, Renee Michelle; Brewe, Eric; Kramer, Laird H.

    2015-06-01

    We investigate the development of expert identities through the use of the sociocultural perspective of learning as participating in a community of practice. An ethnographic case study of biophysics graduate students focuses on the experiences the students have in their research group meetings. The analysis illustrates how the communities of practice-based identity constructs of competencies characterize student expert membership. A microanalysis of speech, sound, tones, and gestures in video data characterize students' social competencies in the physics community of practice. Results provide evidence that students at different stages of their individual projects have opportunities to develop social competencies such as mutual engagement, negotiability of the repertoire, and accountability to the enterprises as they interact with group members. The biophysics research group purposefully designed a learning trajectory including conducting research and writing it for publication in the larger community of practice as a pathway to expertise. The students of the research group learn to become socially competent as specific experts of their project topic and methodology, ensuring acceptance, agency, and membership in their community of practice. This work expands research on physics expertise beyond the cognitive realm and has implications for how to design graduate learning experiences to promote expert identity development.

    2005-01-01

    The publication of The Colorado Plateau: Cultural, Biological, and Physical Research in 2004 marked a timely summation of current research in the Four Corners states. This new volume, derived from the seventh Biennial Conference on the Colorado Plateau in 2003, complements the previous book by focusing on the integration of science into resource management issues. The 32 chapters range in content from measuring human impacts on cultural resources, through grazing and the wildland-urban interface issues, to parameters of climate change on the Plateau. The book also introduces economic perspectives by considering shifting patterns and regional disparities in the Colorado Plateau economy. A series of chapters on mountain lions explores the human-wildland interface. These chapters deal with the entire spectrum of challenges associated with managing this large mammal species in Arizona and on the Colorado Plateau, conveying a wealth of timely information of interest to wildlife managers and enthusiasts. Another provocative set of chapters on biophysical resources explores the management of forest restoration, from the micro scale all the way up to large-scale GIS analyses of ponderosa pine ecosystems on the Colorado Plateau. Given recent concerns for forest health in the wake of fires, severe drought, and bark-beetle infestation, these chapters will prove enlightening for forest service, park service, and land management professionals at both the federal and state level, as well as general readers interested in how forest management practices will ultimately affect their recreation activities. With broad coverage that touches on topics as diverse as movement patterns of rattlesnakes, calculating watersheds, and rescuing looted rockshelters, this volume stands as a compendium of cutting-edge research on the Colorado Plateau that offers a wealth of insights for many scholars.

    The rise of new media and the broader set of social changes they are part of present political communication research with new challenges and new opportunities at a time when many think the field is at an intellectual impasse (e.g., Bennett & Iyengar, 2008). In this article, I argue that parts...... of the field’s problems are rooted in the way in which political communication research has developed since the 1960s. In this period, the field has moved from being interdisciplinary and mixed-methods to being more homogenous and narrowly focused, based primarily on ideas developed in social psychology......, certain strands of political science, and the effects-tradition of mass communication research. This dominant paradigm has contributed much to our understanding of some aspects of political communication.

    2018-02-01

    Novel methodologies utilizing pulsed or intense CW irradiation obtained from lasers have a major impact on biological sciences. In this article, recent development in biophysical researches fully utilizing the laser irradiation is described for three topics, time-resolved fluorescence spectroscopy, time-resolved thermodynamics, and manipulation of the biological assemblies by intense laser irradiation. First, experimental techniques for time-resolved fluorescence spectroscopy are concisely explained in Section 2. As an example of the recent application of time-resolved fluorescence spectroscopy to biological systems, evaluation of the viscosity of lipid bilayer membranes is described. The results of the spectroscopic experiments strongly suggest the presence of heterogeneous membrane structure with two different viscosity values in liposomes formed by a single phospholipid. Section 3 covers the time-resolved thermodynamics. Thermodynamical properties are important to characterize biomolecules. However, measurement of these quantities for short-lived intermediate species has been impossible by traditional thermodynamical techniques. Recently, development of a spectroscopic method based on the transient grating method enables us to measure these quantities and also to elucidate reaction kinetics which cannot be detected by other spectroscopic methods. The principle of the measurements and applications to some protein reactions are reviewed. Manipulation and fabrication of supramolecues, amino acids, proteins, and living cells by intense laser irradiation are described in Section 4. Unconventional assembly, crystallization and growth, amyloid fibril formation, and living cell manipulation are achieved by CW laser trapping and femtosecond laser-induced cavitation bubbling. Their spatio-temporal controllability is opening a new avenue in the relevant molecular and bioscience research fields. This article is part of a Special Issue entitled "Biophysical Exploration of

    In discussing the lessons learned from research in the area of health communication, focus is on basic strategic issues; the scope of health communications in terms of audience, information, education and motivation approaces and India's satellite Instructional Television Experiment (SITE). Health communication is the process by which a health idea is transferred from a source, such as a primary health center, to a receiver, community, with the intention of changing the community's behavior. This involves the formulation of specific strategies for the conduct of health and family welfare communication. In the processs of health communication, it has been a common practice in India as well as in other developing countries to depend upon a plethora of communication media. Yet, despite maximum utilization of the mass media and interpersonal channels of communication, questions remain about the efficacy of the system in bringing about change. Thus, the need to draw upon lessons from research becomes obvious. Communication effectiveness researches have concentrated on 3 basic strategic issues: the question of physical reception of messages by the audience; interpretation or understanding of messages on the part of the audience in accordance with the intention of the communicator; and effectiveness of communication on the cognitive, affective and behavioral dimensions of the audience. Innumberable researches in communication have provided several lessons which have expanded the scope of health communication. This expansion can be observed in terms of audiences reached, information disseminated, education undertaken, and motivation provided. Research has identified several distinct groups to whom specific health messages have to be addressed. These include government and political elites, health and family welfare program administrators, and the medical profession and clinical staff. Information on health needs to include both the concept of health and the pertinent ideas

    2003-01-01

    This work has a biophysical background and uses different examples to demonstrate the practical applicability of NMR-Microscopy in the medical and biological sector. Therefore, the different projects are feasibility studies which are used to compare the possibilities and advantages of NMR-Microscopy with other, established examination techniques. In detail, using MR-Microscopy, different living and fixed biological samples have been visualized non-invasively with high spatial resolution. The specific purpose of the studies ranged from the visualization of the invasion of tumor-spheroids into cell aggregates using T2 parameter maps (time constant of the spin-spin relaxation) to the three-dimensional display of the honey bee brain in the intact head capsule and the non-invasive visualization of the anatomy of prenatal dolphins. For all these projects, the non-invasive character of MR-experiments was of utmost importance. The tumor invasion was not to be disturbed by the measurements, the bee brain should be visualized as close to its true natural shape as possible and the examined dolphins represent rare museum specimens which should not be destroyed. The different samples were all imaged with the best possible spatial resolution which was either limited by the necessary signal-to-noise ratio (SNR) or the available scan time. In order to resolve single details and fine structures in the images, it was necessary to optimize the SNR as well as the contrast-to-noise ratio. To guarantee the necessary SNR, the measurements were performed on high field MR-spectrometers with resonance frequencies of 500 and 750 MHz

    2003-11-01

    Real-time communication has been playing an increasingly important role in our work, life and ocean monitor. With the rapid progress of computer and communication technique as well as the miniaturization of communication system, it is needed to develop the adaptable and reliable real-time communication software in the ocean monitor system. This paper involves the real-time communication software research based on the point-to-point satellite intercommunication system. The object-oriented design method is adopted, which can transmit and receive video data and audio data as well as engineering data by satellite channel. In the real-time communication software, some software modules are developed, which can realize the point-to-point satellite intercommunication in the ocean monitor system. There are three advantages for the real-time communication software. One is that the real-time communication software increases the reliability of the point-to-point satellite intercommunication system working. Second is that some optional parameters are intercalated, which greatly increases the flexibility of the system working. Third is that some hardware is substituted by the real-time communication software, which not only decrease the expense of the system and promotes the miniaturization of communication system, but also aggrandizes the agility of the system.

  11. Biophysical radiosensitization

    International Nuclear Information System (INIS)

    Vladescu, C.; Apetroae, M.

    1983-01-01

    Experimental studies on normal and tumor-bearing rats revealed that chronic treatment with hydroquinone (5 mg/kg/day) inhibited catalase activity in liver, spleen, blood, and H 18R tumor. 3 H-hydroquinone (1.5 μCi/g body weight) showed tumor specificity, with maximum radioactivity in the tumor at 1 h after administration. The biological half-time of 3 H-hydroquinone in the tumor was 2 h, but there seems to exist a longer component, since 24 h after administration, some 30% of the maximum radioactivity could be detected in the tumor. Hydroquinone treatment produces a specific inhibition of catalase in the tumor and a higher degree of oxygenation at this level. These findings support the assumption that the mechanism of action of hydroquinone as an anticancer agent is achieved mainly via peroxide production. The oxygenation of the hypoxic tumoral tissue is done at non-toxic levels of hydroquinone, through a natural and specific biophysical pathway, recommanding hydroquinone for combined anticancer treatment (radiotherapy and chemotherapy).

  12. RESEARCH: Influence of Social, Biophysical, and Managerial Conditions on Tourism Experiences Within the Great Barrier Reef World Heritage Area.

    Shafer; Inglis

    2000-07-01

    / Managing protected areas involves balancing the enjoyment of visitors with the protection of a variety of cultural and biophysical resources. Tourism pressures in the Great Barrier Reef World Heritage Area (GBRWHA) are creating concerns about how to strike this balance in a marine environment. Terrestrial-based research has led to conceptual planning and management frameworks that address issues of human use and resource protection. The limits of acceptable change (LAC) framework was used as a conceptual basis for a study of snorkeling at reef sites in the GBRWHA. The intent was to determine if different settings existed among tourism operators traveling to the reef and, if so, to identify specific conditions relating to those settings. Snorkelers (N = 1475) traveling with tourism operations of different sizes who traveled to different sites completed surveys. Results indicated that snorkelers who traveled with larger operations (more people and infrastructure) differed from those traveling with smaller operations (few people and little on-site infrastructure) on benefits received and in the way that specific conditions influenced their enjoyment. Benefits related to nature, escape, and family helped to define reef experiences. Conditions related to coral, fish, and operator staff had a positive influence on the enjoyment of most visitors but, number of people on the trip and site infrastructure may have the greatest potential as setting indicators. Data support the potential usefulness of visitor input in applying the LAC concept to a marine environment where tourism and recreational uses are rapidly changing.

  19. Enhancing Communication in an Egyptian Research Centre

    International Nuclear Information System (INIS)

    Morsy, S.W.

    2013-01-01

    This paper is a proposed attempt to enhance communication in a research centre in Egypt. The currently Nuclear and Radiological Regulatory Authority (NRRA) which formerly was the National Centre for Nuclear Safety and Radiation Control (NCNSRC) is housed in a nine-storey building with a straight double loaded corridor architectural plan. Syntactic axial analysis showed high integration for each floor plan individually which means that the floor plan is not to be blamed for lack of communication among floor inhabitants; other means must be attempted. But global axial integration (for the whole building) proved to be poor. A problem of communication among floors was identified. Means for enhancing communication were introduced: The lecture hall, the cafe and meeting rooms can play an important role in enhancing global communication among NRRA inhabitants. Besides a questionnaire was designed and distributed on all inhabitants and its feedback came up with ideas which if implemented could result in enhancing the level of communication between the inhabitants of the building thus overcoming spatial hindrances.

    From 1955 to 2001, Japan Atomic Energy Agency (JAEA) carried out research and development projects related to uranium exploration, mining, refining, conversion and enrichment at/around Ningyo-toge in Japan. Subsequently, JAEA has been carrying out remediation of the uranium mine legacy sites and decommissioning of the nuclear fuel cycle facilities. JAEA has many experiences of communication with local stakeholders from these projects. Among such experiences, management of the waste rock sites became local concern in 1988, 27 years after completion of the exploration. The issue was resolved in 2012 after several efforts. From this experience, it was suggested that the lack of information sharing with local stakeholders and that the inadequate support to stakeholder's requests caused the delay of problem solving. Therefore, sustainable relationship with local stakeholders for over decades is important for JAEA Ningyo-toge Environmental Engineering Center. As reference, similar domestic cases were investigated and strategies for risk communication were planned. As follows; (1) Clarify roles and responsibilities of communication staffs for sustainable communicating with local residents. (2) Identify gaps in risk communication knowledge among center and local residents and work toward filling those gaps. (3) Improve the effectiveness of Ningyo-toge center's website and PR-magazines as primary mechanism for communicating with wide stakeholders. (4) Investigate new communication methods for sustainable communicating, such as combination of environmental restoration studies by experts and environmental learning activities by residents.

    Those responsible for state and local radon programs often express frustration about the small share of homes that have been tested for radon, and the small share of those with high readings that have been mitigated. There are now a number of completed studies that have examined how well alternative ways of communicating about radon risk have accomplished the goals of motivating appropriate testing and mitigation. This paper summarizes the research results that are most crucial for planning and implementing effective radon risk communication programs. We identify six reasons why people do not respond to radon as a serious threat and provide some remedies suggested by radon studies

    CERN Document Server

    Vologodskii, Alexander

    2015-01-01

    Surveying the last sixty years of research, this book describes the physical properties of DNA in the context of its biological functioning. It is designed to enable both students and researchers of molecular biology, biochemistry and physics to better understand the biophysics of DNA, addressing key questions and facilitating further research. The chapters integrate theoretical and experimental approaches, emphasising throughout the importance of a quantitative knowledge of physical properties in building and analysing models of DNA functioning. For example, the book shows how the relationship between DNA mechanical properties and the sequence specificity of DNA-protein binding can be analyzed quantitatively by using our current knowledge of the physical and structural properties of DNA. Theoretical models and experimental methods in the field are critically considered to enable the reader to engage effectively with the current scientific literature on the physical properties of DNA.

    Full Text Available Existing discussion of the relationships between globalization, communication research, and qualitative methods emphasizes two images: the challenges posed by globalization to existing communication theory and research methods, and the impact of post-colonial politics and ethics on qualitative research. We draw in this paper on a third image – qualitative research methods as artifacts of globalization – to explore the globalization of qualitative communication research methods. Following a review of literature which tentatively models this process, we discuss two case studies of qualitative research in the disciplinary subfields of intercultural communication and media audience studies. These cases elaborate the forces which influence the articulation of national, disciplinary, and methodological identities which mediate the globalization of qualitative communication research methods.

    2016-01-01

    Biophysical microgravity research on the International Space Station using biological materials has been ongoing for several decades. The well-documented substantive effects of long duration microgravity include the facilitation of the assembly of biological macromolecules into large structures, e.g., formation of large protein crystals under micro-gravity. NASA is invested not only in understanding the possible physical mechanisms of crystal growth, but also promoting two flight investigations to determine the influence of µ-gravity on protein crystal quality. In addition to crystal growth, flight investigations to determine the effects of shear on nucleation and subsequent formation of complex structures (e.g., crystals, fibrils, etc.) are also supported. It is now considered that long duration microgravity research aboard the ISS could also make possible the formation of large complex biological and biomimetic materials. Investigations of various materials undergoing complex structure formation in microgravity will not only strengthen NASA science programs, but may also provide invaluable insight towards the construction of large complex tissues, organs, or biomimetic materials on Earth.

  13. Political communication research: New media, new challenges, and new opportunities

    Directory of Open Access Journals (Sweden)

    Rasmus Kleis Nielsen

    2014-06-01

    Full Text Available The rise of new media and the broader set of social changes they are part of present political communication research with new challenges and new opportunities at a time when many think the field is at an intellectual impasse (e.g., Bennett & Iyengar, 2008. In this article, I argue that parts of the field’s problems are rooted in the way in which political communication research has developed since the 1960s. In this period, the field has moved from being interdisciplinary and mixed-methods to being more homogenous and narrowly focused, based primarily on ideas developed in social psychology, certain strands of political science, and the effects-tradition of mass communication research. This dominant paradigm has contributed much to our understanding of some aspects of political communication. But it is struggling to make sense of many others, including questions concerning people’s experience of political communication processes and questions concerning the symbolic, institutional, and technological nature of these processes—especially during a time of often rapid change. To overcome this problem, I argue that the field of political communication research should re-engage with the rest of media and communication studies and embrace a broader and more diverse agenda. I discuss audience research and journalism studies as examples of adjacent fields that use a more diverse range of theoretical and methodological tools that might help political communication research engage with new media and the new challenges and new opportunities for research that they represent.

    Full Text Available The Radio Frequency (RF communication suffers from interference and high latency issues. Along with this, RF communication requires a separate setup for transmission and reception of RF waves. Overcoming the above limitations, Visible Light Communication (VLC is a preferred communication technique because of its high bandwidth and immunity to interference from electromagnetic sources. The revolution in the field of solid state lighting leads to the replacement of florescent lamps by Light Emitting Diodes (LEDs which further motivates the usage of VLC. This paper presents a survey of the potential applications, architecture, modulation techniques, standardization and research challenges in VLC.

  11. Brazilian science communication research: national and international contributions.

    Science.gov (United States)

    Barata, Germana; Caldas, Graça; Gascoigne, Toss

    2017-08-31

    Science communication has emerged as a new field over the last 50 years, and its progress has been marked by a rise in jobs, training courses, research, associations, conferences and publications. This paper describes science communication internationally and the trends and challenges it faces, before looking at the national level. We have documented science communication activities in Brazil, the training courses, research, financial support and associations/societies. By analyzing the publication of papers, dissertations and theses we have tracked the growth of this field, and compared the level of activity in Brazil with other countries. Brazil has boosted its national research publications since 2002, with a bigger contribution from postgraduate programs in education and communication, but compared to its national research activity Brazil has only a small international presence in science communication. The language barrier, the tradition of publishing in national journals and the solid roots in education are some of the reasons for that. Brazil could improve its international participation, first by considering collaborations within Latin America. International publication is dominated by the USA and the UK. There is a need to take science communication to the next level by developing more sophisticated tools for conceptualizing and analyzing science communication, and Brazil can be part of that.

    2014-12-01

    In order to truly broaden the impact of our scientific community, effective communication should be taught alongside research skills to developing scientists. In the summer of 2014, we incorporated an informal communications course into the 10th year of UNAVCO's Research Experiences in Solid Earth Science for Students (RESESS), a year-long internship program centered around an 11-week intensive summer research experience. The goals of the newly designed course included giving students the tools they need to make a broader impact with their science, starting now; improving the students' confidence in public speaking and using social media for outreach; and giving students the tools they need to apply for jobs or graduate school. Specifically, the course included teaching of professional communication skills, such as e-mail and phone etiquette, resume and CV tailoring, and interview techniques, and public communications skills, such as crafting and simplifying messages, visual communication for the public, and public speaking. Student interns were encouraged to step back from the details of their research projects to put their work into a big-picture context relevant to the public and to policy makers. The course benefited from input and/or participation from UNAVCO Education and Community Engagement staff, engineering and managerial staff, and graduate student interns outside the RESESS program, and University of Colorado research and communications mentors already involved in RESESS. As the summer program is already packed with research and skill development, one major challenge was fitting in teaching these communications skills amongst many other obligations: a GRE course, a peer-focused scientific communications course, a computing course, and, of course, research. Can we do it all? This presentation will provide an overview of the course planning, articulation of course goals, and execution challenges and successes. We will present our lessons learned from

The need for this turn was also pointed out by Habermas (1979, who noticed that the way data was collected in social sciences affected the analysis and data interpretation. Research gained a comprehensive character and proposed a phenomenological approach of reality (Guba & Lincoln, 1994; Willig, 2008; Lindlof & Taylor, 2011. Nowadays, we notice a “more confident community of scholars” whose earlier endeavors had “opened up the study of cultures, meanings, symbolic performances, and social practices” (Lindlof & Taylor, 2002, p. xi.

  17. Communication Capacity Research in the Majority World: Supporting the human right to communication specialist services.

    Science.gov (United States)

    Hopf, Suzanne C

    2018-02-01

    Receipt of accessible and appropriate specialist services and resources by all people with communication and/or swallowing disability is a human right; however, it is a right rarely achieved in either Minority or Majority World contexts. This paper considers communication specialists' efforts to provide sustainable services for people with communication difficulties living in Majority World countries. The commentary draws on human rights literature, particularly Article 19 of the Universal Declaration of Human Rights and the Communication Capacity Research program that includes: (1) gathering knowledge from policy and literature; (2) gathering knowledge from the community; (3) understanding speech, language and literacy use and proficiency; and (4) developing culturally and linguistically appropriate resources and assessments. To inform the development of resources and assessments that could be used by speech-language pathologists as well as other communication specialists in Fiji, the Communication Capacity Research program involved collection and analysis of data from multiple sources including 144 community members, 75 school students and their families, and 25 teachers. The Communication Capacity Research program may be applicable for achieving the development of evidence-based, culturally and linguistically sustainable SLP services in similar contexts.

  18. Science communication in the field of fundamental biomedical research (editorial).

    Science.gov (United States)

    Illingworth, Sam; Prokop, Andreas

    2017-10-01

    The aim of this special issue on science communication is to inspire and help scientists who are taking part or want to take part in science communication and engage with the wider public, clinicians, other scientists or policy makers. For this, some articles provide concise and accessible advice to individual scientists, science networks, or learned societies on how to communicate effectively; others share rationales, objectives and aims, experiences, implementation strategies and resources derived from existing long-term science communication initiatives. Although this issue is primarily addressing scientists working in the field of biomedical research, much of it similarly applies to scientists from other disciplines. Furthermore, we hope that this issue will also be used as a helpful resource by academic science communicators and social scientists, as a collection that highlights some of the major communication challenges that the biomedical sciences face, and which provides interesting case studies of initiatives that use a breadth of strategies to address these challenges. In this editorial, we first discuss why we should communicate our science and contemplate some of the different approaches, aspirations and definitions of science communication. We then address the specific challenges that researchers in the biomedical sciences are faced with when engaging with wider audiences. Finally, we explain the rationales and contents of the different articles in this issue and the various science communication initiatives and strategies discussed in each of them, whilst also providing some information on the wide range of further science communication activities in the biomedical sciences that could not all be covered here.

    Tondoh, E. J.; Forkuor, G.; Adegoke, J. O.

    2017-12-01

    The West African Science Service Centre on Climate Change and Adapted Land Use (WASCAL) is an intergovernmental research organization established in 2012 as result of multilateral collaborations between the Republic of Germany and Governments of 10 West African countries. Its new research program termed WASCAL Research Action Plan (WRAP 2.0) aims to deploy first-class, demand-driven, and impact-oriented research to achieve development outcomes and deliver key science-based climate and environmental services. It's therefore structured around key flagships, including "Sustainable Agriculture and Food Security" with a focus on enhancing the adaptive capacity of socio-ecological landscapes through increased agricultural productivity. However, as land degradation is one of the major obstacles to sustainable agricultural production and food security in sub Saharan African, it's imperative to mitigate this complex multifaceted process which is particularly acute in West African drylands. This case study aims to diagnose the main constraints to sustainable agricultural intensification at landscape scale and derive best bet soil management practices. The methodological approach is built around biophysical survey at sites of 100 km2 organized around 16 clusters each composed of 10 georeferenced sampling plots in three semi-arid agro-ecological landscapes located in upper-west region of Ghana (Lambussie), southwestern Burkina Faso (Bondigui) and southwestern Mali (Finkolo). Soil samples were collected in both the topsoil (0-20cm) and subsoil (20-50) and key soil physical constraints were measured at each sampling point. Remote Sensing (RS) variables representing biomass, climate and topography were correlated with soil organic carbon (SOC) to determine the influence of these variables on soil health. Results revealed within and between site variations in SOC concentration, soil pH, soil fertility index (SFI), erosion prevalence and root depth restriction. Different RS

    This report is the second of two documents that examine the literature for actual examples of organizations and agencies that share communications resources. While the primary emphasis is on rural, intelligent transportation system (ITS) communications involving transit, examples will not be limited to rural activities, nor to ITS implementation, nor even to transit. In addition, the term ''communication'' will be broadly applied to include all information resources. The first document of this series, ''Shared Communications: Volume I. A Summary and Literature Review'', defines the meaning of the term ''shared communication resources'' and provides many examples of agencies that share resources. This document, ''Shared Communications: Volume II. In-Depth Systems Research'', reviews attributes that contributed to successful applications of the sharing communication resources concept. A few examples of each type of communication sharing are provided. Based on the issues and best practice realworld examples, recommendations for potential usage and recommended approaches for field operational tests are provided.

    Nirex is a company financed by the UK nuclear industry to dispose of intermediate and some long-lived low-level radioactive waste. The company has no responsibility for high-level radioactive waste. Most low-level waste is disposed of at a shallow site owned by BNFL, one of Nirex's shareholders. At Nirex, we use opinion research in a number of ways: as a map to guide communications programmes; to set baselines and targets to isolate issues of concern to our publics. The Company carries out market research covering three key audiences: the general public, politicians, and journalists. For Nirex, opinion research is a map. It guides our communication programmes in dealing with our key audiences. Without it, we would be driving blind. Opinion research allows us to isolate key issues for communication. It also allows us to measure performance and to see which initiatives are successful and which are not

    2016-09-01

    Full Text Available Introduction: the issue of development of the communicative competence is well studied in pedagogical theory and practice. Nevertheless there is no consensus among researchers regarding the interpretation of the notion. This fact determines the relevance of the subject in the context of the reform of the national higher education. The labour market puts forward increasing requirements to graduates’ adaption potential within the system “human – human”. This draws special attention to the problem of communicative co mpetence. Materials and Methods: the authors carried out a sociological research on the communicative component of the competence cluster among master’s degree students who specialise in pedagogical education in order to determine “the importance of weight indicators” of separate competencies. Results: the authors substantiate the necessity of broadening a communicative competence in conditions of transition to a multilevel system of higher education; define its essence and structure taking into account the generic unity of Bachelor’s and Master’s degree programmes. The article presents the informative content of communication components in accordance with the proposed structure of communicative competence, containing motivation-value-based, cognitive, activity-based, reflective and evaluative components. The authors show the potential of communicative competence in the context of the new federal state educational standards (FGOS VO 3+. Further the authors make analysis of the requirements set to graduates upon completion of undergraduate and graduate programmes in “Pedagogical Education”, specify the role of separate competencies in extending graduates’ communicative competence. Discussion and Conclusions: the results of the research presented in the article enable to specify the structure and content of the communicative competence of a university graduate, reflecting the willingness and ability to productive

    Previous arguments that content analyses provide the descriptive foundation for media effects research (McLeod & Reeves, 1980) are extended to include that content analyses can provide a sound and useful foundation for programmatic research by individual communication scientists. I discuss examples from my own work and from that of colleagues in communication and related disciplines. Use of messages sampled and coded in a content analysis in combination with survey data sets or as stimuli in experiments are highlighted. The particular potential for employing larger numbers of randomly sampled messages in experimental designs, and, with use of appropriate statistical methods, being able to generalize to populations of messages, is described.

    Relationship behaviors contribute to compromised health or resilience. Everyday communication between intimate partners represents the vast majority of their interactions. When intimate partners take on new roles as patients and caregivers, everyday communication takes on a new and important role in managing both the transition and the adaptation to the change in health status. However, everyday communication and its relation to health has been little studied, likely due to barriers in collecting and processing this kind of data. The goal of this paper is to describe deterrents to capturing naturalistic, day-in-the-life communication data and share how technological advances have helped surmount them. We provide examples from a current study and describe how we anticipate technology will further change research capabilities. Copyright © 2017 Elsevier B.V. All rights reserved.

    Ten years ago, scholars suggested that risk communication was embarking on a new phase that would give increased attention to the social contexts that surround and encroach on public responses to risk information. A decade later, many researchers have answered the call, with several defining studies examining the social and psychological influences on risk communication. This article reviews risk communication research appearing in the published literature since 1996. Among studies, social trust, the social amplification of risk framework, and the affect heuristic figured prominently. Also common were studies examining the influence of risk in the mass media. Among these were content analyses of media coverage of risk, as well as investigations of possible effects resulting from coverage. The use of mental models was a dominant method for developing risk message content. Other studies examined the use of risk comparisons, narratives, and visuals in the production of risk messages. Research also examined how providing information about a risk's severity, social norms, and efficacy influenced communication behaviors and intentions to follow risk reduction measures. Methods for conducting public outreach in health risk communication rounded out the literature.

    With an ever-increasing amount of research, there is a parallel challenge to mobilize the research for decision making, policy development and management actions. The tradition of "loading dock" model of science to policy is under renovation, replaced by more engaging methods of research communication. Research communication falls on a continuum from passive methods (e.g. reports, social media, infographics) to more active methods (e.g. forum theatre, decision labs, and stakeholder planning, and mix media installations that blend, art, science and traditional knowledge). Drawing on a five-year water science research program in the Saskatchewan River Basin, an evaluation framework is presented that draws on a wide communities of knowledge users including: First Nation and Metis, Community Organizers, Farmers, Consultants, Researchers, and Civil Servants. A mixed method framework consisting of quantitative surveys, qualitative interviews, focus groups, and q-sorts demonstrates that participants prefer more active means of research communication to draw them into the research, but they also value more traditional and passive methods to provide more in-depth information when needed.

  20. Educating to Tolerance: Effects of Communicating Social Psychology Research Findings

    2015-08-01

    Full Text Available The effect of communicating social psychology research findings on ingroup bias in a classroom setting has been investigated. Two hundred and twenty one high school students either read or did not read a brief report about three classical social psychological studies, then completed evaluation scales for the ingroup and the outgroup. Participants’ motivation was manipulated, and the messages were different as regards the congruency between the content and participants’ actual intergroup experience. Results showed that communication exerted a significant effect in reducing ingroup bias for participants in the high motivation/high congruency condition, that is, the communication effect was moderated by the individual’s level of motivation and the content of the arguments proposed in the report. Practical implications of results for education work and stereotype change, limitations of the study, as well as possible directions for future research are discussed.

    2006-01-01

    Full Text Available Introduction. This is the written version of the keynote address (Making user studies matter: Thank you Mister Feynman and Monsieur Foucault delivered by senior author Dervin. The paper is linked to the Invited Paper in this issue and like that paper, reports on a project involving a dialogue between researchers and practitioners in library and information science, human computer interaction, and communication focusing on gaps in our understandings of users and audiences as well as in our efforts to collaborate with each other to conduct and apply research to the design and implementation of information, library, communication, and media systems. Argument. Our main conclusion in Paper 1 was that the traditional modes used for communication in social science research are not doing the job for user and audience studies. We set out five propositions relating to this conclusion: (1 the traditional modes of communicating in the research enterprise are not working; (2 Do the social sciences matter? Some serious and fundamental attacks; (3 a call to focus on the special problematics of the social sciences: agency, structure, power and the good; (4 eschewing scientific recipes and scholarly creeds and bringing back the joys of adventuring and muddling; (5 the paradox of communicating—freedom is another word for nothing left to lose. Conclusion. We argue for shared dialogue in communicating across the three fields studied here: this will introduce uncertainty, but, rather than relying upon 'authority', the individual will be encouraged through the exploration of that uncertainty, to make their own sense of the offerings of others.

  14. Biophysics and systems biology.

    Science.gov (United States)

    Noble, Denis

    2010-03-13

    Biophysics at the systems level, as distinct from molecular biophysics, acquired its most famous paradigm in the work of Hodgkin and Huxley, who integrated their equations for the nerve impulse in 1952. Their approach has since been extended to other organs of the body, notably including the heart. The modern field of computational biology has expanded rapidly during the first decade of the twenty-first century and, through its contribution to what is now called systems biology, it is set to revise many of the fundamental principles of biology, including the relations between genotypes and phenotypes. Evolutionary theory, in particular, will require re-assessment. To succeed in this, computational and systems biology will need to develop the theoretical framework required to deal with multilevel interactions. While computational power is necessary, and is forthcoming, it is not sufficient. We will also require mathematical insight, perhaps of a nature we have not yet identified. This article is therefore also a challenge to mathematicians to develop such insights.

    Pelto, M. S.

    2014-12-01

    This talk will focus on the changes in communicating science in the last 20 years from the perspective of the same research project. Essentially the rapid innovation in online communication requires the scientist learning and utilizing a new platform of communication each year. To maintain relevant visibility and ongoing research activities requires finding synergy between the two. I will discuss how digital communication has inspired my research efforts. This talk will also examine overall visitation and media impact metrics over this period. From developing a highly visible glacier research web page in 1996, to writing more than 400 blog posts since 2008, and in 2014 utilizing a videographer and illustration artist in the field, this is the story of one scientist's digital communication-media evolution. The three main observations are that: 1) Overall visitation has not expanded as rapidly in the last decade. 2) Contact and cooperation with colleagues has expanded quite rapidly since 2008. 3) Media impact peaked in 2005, but is nearing that peak again. The key factors in visibility and media impact for a "small market" research institution/project has been providing timely and detailed content to collaborative sites, such as RealClimate, BAMS State of the Climate, Climate Denial Crock of the Week, and Skeptical Science that can then be repurposed by the media. A review of the visitor metrics to the digital glacier sites I have maintained from 1996-2014 indicate visibility of each platform has a similar growth curve, transitioning to a plateau, but overall visitation does not increase in kind with the increase in number of platforms. Media metrics is more event driven and does not follow the visitor metric pattern.

  16. Communicating in context: a priority for gene therapy researchers.

    Science.gov (United States)

    Robillard, Julie M

    2015-03-01

    History shows that public opinion of emerging biotechnologies has the potential to impact the research process through mechanisms such as funding and advocacy. It is critical, therefore, to consider public attitudes towards modern biotechnology such as gene therapy and more specifically towards the ethics of gene therapy, alongside advances in basic and clinical research. Research conducted through social media recently assessed how online users view the ethics of gene therapy and showed that while acceptability is high, significant ethical concerns remain. To address these concerns, the development of effective and evidence-based communication strategies that engage a wide range of stakeholders should be a priority for researchers.

    2016-02-01

    Full Text Available This article argues that an indigenous approach to communication research allows us to re-think academic approaches of engaging in and evaluating participatory communication research. It takes as its case study the Komuniti Tok Piksa project undertaken in the Highlands of Papua New Guinea. The project explores ways in which visual methods when paired with a community action approach embedded within an indigenous framework can be used to facilitate social change through meaningful participation. It involves communities to narrate their experiences in regard to HIV and AIDS and assists them in designing and recording their own messages. Local researchers are trained in using visual tools to facilitate this engagement with the communities.

    With the highlights of the high transmission rate, large capacity, strong anti-interference and anti-capture ability, good security and small light, space laser communication becomes an important hotspot. At present, the focus of research of the laser communication system is point to point communication structure. However, from the application point of view, both the realization of space laser communication among multiple points and the establishment of the information transmission network can really have the practical value. Aiming at the problem of space laser communication network, this article puts forward the general idea about optical antenna to achieve multiple tracking goals at the same time. Through the analysis of the optical antenna, and the comparing of the current commonly used mirror driving mechanism, a new mirror driving mechanism is designed. The azimuth motion, containing circular grating feedback, is driven by torque motor,voice coil motor of fan produces pitch motion that has fan-shaped grating feedback, so that compression of the structure size to improve the efficiency of the reflector assembly. Through the establishment of the driving mechanism and the kinematic model of 3D entity, the relationship between the single drive azimuth and pitch angle following the angle of incident light is explained. The biggest ideal view area affecting the optical antenna is obtained by the simulation analysis of the kinematics model using MATLAB. The several factors of field overlap area and blind area offers a theoretical basis for structure optimization and control system for the subsequent optical antenna design.

    In a demonstration experiment bacterium sporules have been exposed to the space vacuum and to the solar radiation field at 254 nm, with the following results: 1) a short vacuum exposition of 1.3 h does not affect the vitality of the sporules, 2) the survival rate of humid sporules after UV-irradiation is consistent with terrestrial control samples, 3) after a simultaneous exposition to vacuum and solar UV-radiation the effect on the sporules is enhanced by a factor of ten as compared to the situation without vaccum exposition. Additional studies in biophysical simulation systems revealed, that the enhanced UV sensitivity is caused by the dehydration of the sporules. By this process the structure of the essential macromolecules in cell, such as DNA and proteins, is modified such that new photo-products can be formed. For these products the cells have no effective repair systems. (AJ) [de

    1984-01-01

    Understanding the cellular response to ionizing radiation is not only necessary to meet the requirements of radioprotection, but also for medical application of radiation in cancer treatment. In terms of radiobiology, cancer therapy means the selective inactivation of malignant cells without affecting the normal healthy tissue. However, for several physical and biological reasons, this ideal situation is normally not attained. The elaboration of biophysical parameters that could be used to improve the selective sterilization of tumor cells has become one of the main activities of cellular radiobiology during the last two decades. Progress in this field has been facilitated by the development of tissue culture techniques allowing to grow and analyze cells in a synthetic nutrient medium. This chapter describes the physical and biological factors which determine cellular radiosensitivity and which are important to know for better understanding the cellular radiation action, in particular with reference to cancer treatment

    CERN Document Server

    Scherer, Philipp O J

    2017-01-01

    This book gives an introduction to molecular biophysics. It starts from material properties at equilibrium related to polymers, dielectrics and membranes. Electronic spectra are developed for the understanding of elementary dynamic processes in photosynthesis including proton transfer and dynamics of molecular motors. Since the molecular structures of functional groups of bio-systems were resolved, it has become feasible to develop a theory based on the quantum theory and statistical physics with emphasis on the specifics of the high complexity of bio-systems. This introduction to molecular aspects of the field focuses on solvable models. Elementary biological processes provide as special challenge the presence of partial disorder in the structure which does not destroy the basic reproducibility of the processes. Apparently the elementary molecular processes are organized in a way to optimize the efficiency. Learning from nature by means exploring the relation between structure and function may even help to b...

    Since the early times of the Greek philosophers Leucippus and Democritus, and later of the Roman philosopher Lucretius, a simple, fundamental idea emerged that brought the life sciences into the realm of the physical sciences. Atoms, after various interactions, were assumed to acquire stable configurations that corresponded either to the living or to the inanimate world. This simple and unitary theory, which has evolved in successive steps to our present time, remarkably maintained its validity despite several centuries of alternative vicissitudes, and is the foundation of modern biophysics. Some of the recent developments of this ancient idea are the discovery of the direct relationship between spatial structures and chemical activity of such molecules as methane and benzene, and the later discovery of the three-dimensional structure of double-helical DNA, and of its relationship with biological activity. The relationship between the structure of various macromolecules and the function of living cells was on...

    Student creation of well-designed and engaging visuals in science communication can enhance their deep learning while streamlining the transmission of information to their audience. However, undergraduate research training does not frequently emphasize the design aspect of science communication. We devised and implemented a new curricular component to the Lake Champlain NSF Research Experiences for Undergraduates (REU) program in Vermont. We took a holistic approach to communication training, with a targeted module in "art and science". Components to the module included: 1) an introduction to environmental themes in fine art, 2) a photography assignment in research documentation, 3) an overview of elements of design (e.g., color, typography, hierarchy), 4) a graphic design workshop using tools in Powerpoint, and 5) an introduction to scientific illustration. As part of the REU program, students were asked to document their work through photographs, and develop an infographic or scientific illustration complementary to their research. The "art and science" training culminated with a display and critique of their visual work. We report on student responses to the "art and science" training from exit interviews and survey questions. Based on our program, we identify a set of tools that mentors can use to enhance their student's ability to engage with a broad audience.

  8. Optimizing Communications Between Arctic Residents and IPY Scientific Researchers

    2007-12-01

    BACKGROUND International Polar Year, which was launched in March 2007, is an international program of coordinated, interdisciplinary scientific research on Earth's polar regions. The northern regions of the eight Arctic States (Canada, Alaska (USA), Russia, Sweden, Norway, Finland. Iceland and Greenland (Denmark) have significant indigenous populations. The circumpolar Arctic is one of the least technologically connected regions in the world, although Canada and others have been pioneers in developing and suing Information and Communication Technology (ICT) in remote areas. The people living in this vast geographic area have been moving toward taking their rightful place in the global information society, but are dependent on the outreach and cooperation of larger mainstream societies. The dominant medium of communication is radio, which is flexible in accommodating multiple cultures, languages, and factors of time and distance. The addition of newer technologies such as streaming on the Internet can increase access and content for all communities of interest, north and south. The Arctic Circle of Indigenous Communicators (ACIC) is an independent association of professional Northern indigenous media workers in the print, radio, television, film and Internet industries. ACIC advocates the development of all forms of communication in circumpolar North areas. It is international in scope. Members are literate in English, French, Russian and many indigenous languages. ACIC has proposed the establishment of a headquarters for monitoring IPY projects are in each area, and the use of community radio broadcasters to collect and disseminate information about IPY. The cooperation of Team IPY at the University of Colorado, Arctic Net at Laval University, and others, is being developed. ACIC is committed to making scientific knowledge gained in IPY accessible to those most affected - residents of the Arctic. ABSTRACT The meeting of the American Geophysical Union will be held

    To judge from the rapidly growing body of research in the field of corporate social responsibility (CSR) management and marketing communication, there is an increasing interest in exploring the role of communication along with the transmission from implicit towards explicit CSR in the European...... context (Matten & Moon 2008). Many corporations today are concerned with gaining legitimacy through integrating the expectations of their stakeholders (employees, customers, NGOs, activists, government institutions, institutions of international governance) in the overall company strategy. This also...... includes stakeholders in or around business units established in developing countries and emerging markets (e.g. Jamali 2010; Reimann 2012). Along with the growing pressure on corporations to engage in CSR a seemingly growing number of these are concerned with disclosure, reporting, reputation, etc. issues...

    Coordinating and controlling large numbers of autonomous or semi-autonomous robot elements in a space construction activity will present problems that are very different from most command and control problems encountered in the space business. As part of our research into the feasibility of robot constructors in space, the CSC Operations Group is examining a variety of command, control, and communications (C3) issues. Two major questions being asked are: can we apply C3 techniques and technologies already developed for use in space; and are there suitable terrestrial solutions for extraterrestrial C3 problems? An overview of the control architectures, command strategies, and communications technologies that we are examining is provided and plans for simulations and demonstrations of our concepts are described.

  12. Biophysics of protein evolution and evolutionary protein biophysics

    2014-01-01

    The study of molecular evolution at the level of protein-coding genes often entails comparing large datasets of sequences to infer their evolutionary relationships. Despite the importance of a protein's structure and conformational dynamics to its function and thus its fitness, common phylogenetic methods embody minimal biophysical knowledge of proteins. To underscore the biophysical constraints on natural selection, we survey effects of protein mutations, highlighting the physical basis for marginal stability of natural globular proteins and how requirement for kinetic stability and avoidance of misfolding and misinteractions might have affected protein evolution. The biophysical underpinnings of these effects have been addressed by models with an explicit coarse-grained spatial representation of the polypeptide chain. Sequence–structure mappings based on such models are powerful conceptual tools that rationalize mutational robustness, evolvability, epistasis, promiscuous function performed by ‘hidden’ conformational states, resolution of adaptive conflicts and conformational switches in the evolution from one protein fold to another. Recently, protein biophysics has been applied to derive more accurate evolutionary accounts of sequence data. Methods have also been developed to exploit sequence-based evolutionary information to predict biophysical behaviours of proteins. The success of these approaches demonstrates a deep synergy between the fields of protein biophysics and protein evolution. PMID:25165599

    2015-12-01

    The Dark Snow Project, to crowd fund and communicate Greenland ice-climate interactions expedition research, was a baptism by fire climate communications venture. We did it without a guide book and ran on pure inspiration. Along the way, we acquired quite some of the communication skill set: marketing; social psychology; crowd funding; conventional media; video production; social media.The aim of this presentation is to inventory lessons learned, experience, and resolve recommendations how to do it better for those adventurous enough to do a crowd funded actvity. Key themes are amplifying basic research, engagement in citizen science, outreach, communication.Quickly, one begins thinking of success tactics, like launching news on a Monday instead of a Saturday or keeping the conversation going by telling the story from different and evolving perspectives. The experience taught that unconventional funding is harder won than conventional funding. Yet, because the support came from unconventional sources, the public, we began tapping a large resource in citizen science engagement. If having a compelling call to action such a campaign can be a significant source of sustain. What had also proven difficult was doing it with a small team when each of the following skills demands a larger group; running a media campaign; logistics; video recording and editing; social media promotion; conventional media engagement. The issue and brand awareness grows in a snowball effect encouraging us to run successive annual campaigns.Now in third year, the project can be more effective if upscaling from a single to a multi-cell organization.

    2015-04-01

    How effective is visual communication to increase awareness of natural hazards and risks? To answer this research question, we developed a research design that was at the same time an experimental setting and an actual communication effort. Throughout the full length of the 2-years project held in the Ubaye valley (southeastern France), we collaborated with local and regional stakeholders (politicians and technicians). During a consultation phase, the communication context was determined, the audience of the project was defined and finally the testing activity-communication effort was determined. We were offered the opportunity to design an exhibition for the local public library. In a consultation phase that corresponded to the design of the exhibition, the stakeholders contributed to its content as well as helping with the funding of the exhibition. Finally, during the experimentation phase, the stakeholders participated in advertising the activity, gathering of participants and designing the scientific survey. In order to assess the effects of the exhibition on risk awareness, several groups of children, teenagers and adults were submitted to a research design, consisting of 1) a pre-test, 2) the visit of the exhibition and 3) a post-test similar to the pre-test. In addition, the children answered a second post-test 3 months after the visit. Close ended questions addressed the awareness indicators mentioned in the literature, i.e. worry level, previous experiences with natural hazards events, exposure to awareness raising, ability to mitigate/respond/prepare, attitude to risk, and demographics. In addition, the post-test included several satisfaction questions concerning the visual tools displayed in the exhibition. A statistical analysis of the changes between the pre- and post- tests (paired t-test, Wilcoxon signed-rank test and bootstrapping) allowed to verify whether the exhibition had an impact on risk awareness or not. In order to deduce which variable

    2014-12-01

    Poor patient-provider communication in hospital continues to be cited as a possible causal factor in preventable adverse events for patients with severe communication disabilities. Yet to date there are no reports of empirical interventions that investigate or demonstrate an improvement in communication in hospital for these patients. The aim of this review was to synthesize the findings of research into communication in hospital for people with severe communication disabilities arising from lifelong and acquired stable conditions including cerebral palsy, autism, intellectual disability, aphasia following stroke, but excluding progressive conditions and those solely related to sensory impairments of hearing or vision. Results revealed six core strategies suggested to improve communication in hospital: (a) develop services, systems, and policies that support improved communication, (b) devote enough time to communication, (c) ensure adequate access to communication tools (nurse call systems and communication aids), (d) access personally held written health information, (e) collaborate effectively with carers, spouses, and parents, and (f) increase the communicative competence of hospital staff. Currently there are no reports that trial or validate any of these strategies specifically in hospital settings. Observational and evaluative research is needed to investigate the ecological validity of strategies proposed to improve communication.

  17. Enhancing Environmental Communication and Products Through Qualitative Research

    DeLorme, D.; Hagen, S. C.

    2014-12-01

    This presentation discusses two ongoing interdisciplinary case studies that are using qualitative research to design and enhance environmental communication and science products for outreach and decision making purposes. Both cases demonstrate the viability and practical value of qualitative social science methodology, specifically focus group interviews, to better understand the viewpoints of target audiences, improve deliverables, and support project goals. The first case is a NOAA-funded project to conduct process-based modeling to project impact from climate change in general and sea level rise in particular to the natural and built environment. The project spans the Mississippi, Alabama, and Florida Panhandle coasts with concentration on the three National Estuarine Research Reserves. As part of the broader project, four annual focus groups were conducted with a purposive sample of coastal resource managers to capture their perspectives and suggestions to better meet their informational and operational needs. The second case is a Florida Sea Grant-funded project that is developing, implementing, and testing a cohesive outreach campaign to promote voluntary careful and responsible recreational boating to help protect sensitive marine life and habitats (especially seagrasses and oyster reefs) in the Mosquito Lagoon. Six focus groups were conducted with a purposive sample of the target audience of boaters to gain insights, feedback, and ideas on the direction of the campaign and design of the messages and products. The campaign materials created include a branded website, Facebook page, mobile app, information packets, brochures, pledge forms, and promotional items. A comparison of these two case studies will be provided and will explain how the qualitative findings were/are being implemented to tailor and refine the respective communication strategies and techniques including the emerging outreach products. The resulting outcomes are messages and tools that are

  20. Knowledge Integration and Inter-Disciplinary Communication in Action Research

    Directory of Open Access Journals (Sweden)

    Hahn Heidi Ann

    2014-08-01

    Full Text Available In a plenary talk at WMSCI 2012 entitled "Planning for Action Research: Looking at Practice through a Different Lens," this author asserted that behavioral science practitioners, often "back into" action research – they start out doing a process improvement or intervention and discover something along the way, i.e., generalizable knowledge, that seems worthwhile to share with their community of practice. It was further asserted that, had the efforts been conceived of as research from the outset, the contributions to the body of knowledge would be more robust and the utility of the projects would improve as well. This paper continues on that theme. Action research and process improvement methods are briefly described and compared. A comparison of two Los Alamos National Laboratory engineering ethics training projects – one developed using a process improvement framework, the other using an action research framework – is put forth to provide evidence that use of a research "lens" can enhance behavioral science interventions and the knowledge that may result from them. The linkage between the Specifying Learning and Diagnosing stages of the Action Research Cycle provides one mechanism for integrating the knowledge gained into the product or process being studied and should provide a reinforcing loop that leads to continual improvement. The collaborative relationships among researchers and the individual, group, or organization that is the subject of the imp rovement op p ortunity (the "client", who are likely from very different backgrounds, and the interpretive epistemology that are among the hallmarks of action research also contribute to the quality of the knowledge gained. This paper closes with a discussion of how Inter-Disciplinary Communication is embedded within the action research paradigm and how this likely also enriches the knowledge gained.

  1. An introduction to environmental biophysics

    CERN Document Server

    Campbell, Gaylon S

    1977-01-01

    The study of environmental biophysics probably began earlier in man's history than that of any other science. The study of organism-environment interaction provided a key to survival and progress. Systematic study of the science and recording of experimental results goes back many hundreds of years. Ben­ jamin Franklin, the early American statesman, inventor, printer, and scientist studied conduction, evaporation, and radiation. One of his observations is as follows: My desk on which I now write, and the lock of my desk, are both exposed to the same temperature of the air, and have therefore the same degree of heat or cold; yet if I lay my hand successively on the wood and on the metal, the latter feels much the coldest, not that it is really so, but being a better conductor, it more readily than the wood takes away and draws into itself the fire that was in my skin. 1 Franklin probably was not the first to discover this principle, and certainly was not the last. Modem researchers rediscover this principle f...

  2. Transformation and communication research strategies: language - society – culture

    Directory of Open Access Journals (Sweden)

    S. M. Forkosh

    2017-06-01

    Full Text Available Main research strategies in the humanitarian sphere, connected with the transformation-communicative approach by K.-O. Apel, have been studied in the article. This approach is based on I. Kant’s classic transcendental method, but has much wider sphere of application. Syncretic tendencies in humanitarian sciences cause the search of criteria or generalizing principles, which would allow not only combining basic research strategies, but also covering variable forms of the social-dynamics. Language in its various forms becomes the common ground, where it is possible not only to describe, but to explain disparate elements of the society’s functioning. These elements, when developed, cause the formation of culture. The basis for the analysis of the interdisciplinary communication features are relevant branches of philosophy. Specific realities of the research activity are understood by the methodologist as the deep interrelation of language tools and specific features of scientific knowledge’s changes. In fact, the researcher simultaneously performs double task: interprets scientific texts, improves his/her understanding of their structural characteristics, and also studies social, cultural, humanistic priorities of the available practices. Based on the characteristics of the modern culture (rapidity of development, lack of self-awareness and «maturation» vector, non-manifestation of methodological tools, sociological and linguistic sciences become to be a model in the humanitarian area. At the same time, awareness of the structural maturation of such knowledge is low. The development of linguistic sciences has more advanced conceptual design and it resonates with the evolution of the language philosophy. That’s why, considering the socio-cultural transformations of the globalization era, grounds of clarification of the specific methodological potential, which are accumulated in the contemporary linguistics, should be considered. In this

    In building public support for social change, activists in communities of color routinely approach broader audiences via news media. Communities of color, however, routinely face disparities that limit their access to media including local news media outlets. This lack of access mirrors inequalities in political, social, and economic arenas and can slow public awareness campaigns to address disparities in health, environmental, and other quality-of-life issues. I describe two community-based collaborative action research studies that documented and challenged how local television newscasts underrepresented and misrepresented three communities of color in Boston. The linkage between communication rights and campaigns to address quality-of-life issues is presented, as well as unresolved challenges in the collaborative research process. The study has implications for environmental health campaigns.

    2018-06-01

    In the last 20 years, qualitative research scholars have begun to interrogate methodological and analytic issues concerning online research settings as both data sources and instruments for digital methods. This article examines the adaptation of parts of a qualitative research curriculum for understanding online communication settings. I propose methodological best practices for researchers and educators that I developed while teaching research methods to undergraduate and graduate students across disciplinary departments and discuss obstacles faced during my own research while gathering data from online sources. This article confronts issues concerning the disembodied aspects of applying what in practice should be rooted in a humanistic inquiry. Furthermore, as some approaches to online qualitative research as a digital method grow increasingly problematic with the development of new data mining technologies, I will also briefly touch upon borderline ethical practices involving data-scraping-based qualitative research.

    2003-08-08

    This work has a biophysical background and uses different examples to demonstrate the practical applicability of NMR-Microscopy in the medical and biological sector. Therefore, the different projects are feasibility studies which are used to compare the possibilities and advantages of NMR-Microscopy with other, established examination techniques. In detail, using MR-Microscopy, different living and fixed biological samples have been visualized non-invasively with high spatial resolution. The specific purpose of the studies ranged from the visualization of the invasion of tumor-spheroids into cell aggregates using T2 parameter maps (time constant of the spin-spin relaxation) to the three-dimensional display of the honey bee brain in the intact head capsule and the non-invasive visualization of the anatomy of prenatal dolphins. For all these projects, the non-invasive character of MR-experiments was of utmost importance. The tumor invasion was not to be disturbed by the measurements, the bee brain should be visualized as close to its true natural shape as possible and the examined dolphins represent rare museum specimens which should not be destroyed. The different samples were all imaged with the best possible spatial resolution which was either limited by the necessary signal-to-noise ratio (SNR) or the available scan time. In order to resolve single details and fine structures in the images, it was necessary to optimize the SNR as well as the contrast-to-noise ratio. To guarantee the necessary SNR, the measurements were performed on high field MR-spectrometers with resonance frequencies of 500 and 750 MHz.

    2010-01-01

    For a long time, neuroscience has focused on biochemical, molecular biological and electrophysiological aspects of neuronal physiology and pathology. However, there is a growing body of evidence indicating the importance of physical stimuli for neuronal growth and development. In this review we briefly summarize the historical background of neurobiophysics and give an overview over the current understanding of neuronal growth from a physics perspective. We show how biophysics has so far contributed to a better understanding of neuronal growth and discuss current inconsistencies. Finally, we speculate how biophysics may contribute to the successful treatment of lesions to the central nervous system, which have been considered incurable until very recently.

    Environmental news mainly reach not specialist people by mass media, which generally focuses on fascinating or catastrophic events without reporting scientific data. Otherwise, scientific data on environment are published in peer-reviewed journals with specific language, so they could be not understandable to common people. In the last decade, Internet spread made easier to divulge environmental information. This allows everyone (scientist or not) to publish information without revision. In fact, World Wide Web includes many scientific sites with different levels of confidence. Within Italian scientific websites, there are those of University and Research Centre, but they mainly contain didactic and bureaucratic information, generally lacking in research news, or reporting them in peer-reviewed format. University and Research Centre should have an important role to divulge certified information, but news should be adapted to a general audience without scientific skills, in order to help population to gain knowledge on environmental issues and to develop responsible behavior. Therefore, an attractive website (www.sunability.unina2.it) has been created in order to divulge research products of Environmental, Biological and Pharmaceutical Sciences and Technologies Department (DiSTABiF) of Second University of Naples-SUN (Campania, Southern Italy). This website contains divulgation articles derived from peer-reviewed publications of DiSTABiF researchers and concerning studies on environmental, nutrition, and health issues, closely related topics. Environmental studies mainly referred to Caserta district (Southern Italy), where DiSTABiF is located. Divulgation articles have been shared by main social networks (Facebook: sunability, Twitter: @SUNability) and accesses have been monitored for 28 days in order to obtain demographic and geographic information about users and visualization number of both DiSTABiF website and social network pages.

    Underwater noise, whether of natural or anthropogenic origin, has the ability to interfere with the way in which marine mammals receive acoustic signals (i.e., for communication, social interaction, foraging, navigation, etc.). This phenomenon, termed auditory masking, has been well studied in humans and terrestrial vertebrates (in particular birds), but less so in marine mammals. Anthropogenic underwater noise seems to be increasing in parts of the world's oceans and concerns about associated bioacoustic effects, including masking, are growing. In this article, we review our understanding of masking in marine mammals, summarise data on marine mammal hearing as they relate to masking (including audiograms, critical ratios, critical bandwidths, and auditory integration times), discuss masking release processes of receivers (including comodulation masking release and spatial release from masking) and anti-masking strategies of signalers (e.g. Lombard effect), and set a research framework for improved assessment of potential masking in marine mammals.

    Ftacnikova, S.

    1998-01-01

    The Cyclotron Laboratory (CYLAB) should fill the gap in the field of nuclear medicine, radiotherapy, basic research, metrology of ionizing radiation, education and implications of accelerator technology existing today in Slovak Republic. The main planned activities of this facility are in the fields of nuclear medicine (production of radioisotopes for Positron Emission Tomography - PET and for oncology) and radiotherapy (neutron capture therapy, fast neutron therapy and proton therapy). The radiobiological and biophysical research will be closely connected with medical applications, particularly with radiotherapy. Problems to be addressed include the determination of the values of Relative Biological Effectiveness (RBE) for different types of ionizing radiation involved in the therapy, microdosimetric measurements and calculations, which are indispensable in the calculation of the absorbed dose (lineal and specific energy spectra) at the cellular and macromolecular level. Radiation biophysics and medical physics help in creating therapeutic plans for radiotherapy (NCT and fast neutron therapy). In nuclear medicine, in diagnostic and therapeutical procedures it is necessary to assess the biodistribution of radiopharmaceuticals and to calculate doses in target and critical organs and to determine whole body burden - effective equivalent dose for newly developed radiopharmaceuticals

  13. Visualization and Interaction in Research, Teaching, and Scientific Communication

    Science.gov (United States)

    Ammon, C. J.

    2017-12-01

    Modern computing provides many tools for exploring observations, numerical calculations, and theoretical relationships. The number of options is, in fact, almost overwhelming. But the choices provide those with modest programming skills opportunities to create unique views of scientific information and to develop deeper insights into their data, their computations, and the underlying theoretical data-model relationships. I present simple examples of using animation and human-computer interaction to explore scientific data and scientific-analysis approaches. I illustrate how valuable a little programming ability can free scientists from the constraints of existing tools and can facilitate the development of deeper appreciation data and models. I present examples from a suite of programming languages ranging from C to JavaScript including the Wolfram Language. JavaScript is valuable for sharing tools and insight (hopefully) with others because it is integrated into one of the most powerful communication tools in human history, the web browser. Although too much of that power is often spent on distracting advertisements, the underlying computation and graphics engines are efficient, flexible, and almost universally available in desktop and mobile computing platforms. Many are working to fulfill the browser's potential to become the most effective tool for interactive study. Open-source frameworks for visualizing everything from algorithms to data are available, but advance rapidly. One strategy for dealing with swiftly changing tools is to adopt common, open data formats that are easily adapted (often by framework or tool developers). I illustrate the use of animation and interaction in research and teaching with examples from earthquake seismology.

  14. The ethics of good communication in a complex research partnership.

    Science.gov (United States)

    Sodeke, Stephen; Turner, Timothy; Tarver, Will

    2010-08-01

    The tripartite partnership among Morehouse School of Medicine, Tuskegee University, and University of Alabama at Birmingham is complex. In 2005, the three schools--with different institutional cultures, characters, and resources--agreed to collaborate in efforts to eliminate racial/ethnic disparities in cancer burdens. Pursuing this laudable aim predictably involved some miscommunication. The Bioethics Shared Resource (BSR) group foresaw such challenges and monitored interactions to prevent harm, noting that while effective communication is critical to the achievement of mutual goals, an understanding and prudent use of proven communication principles is a sine qua non for success. In this commentary, we share the undergirding moral concepts, communication approaches, and lessons learned. This experience has led us to propose an ethics of good communication for others to consider.

  16. Yugonostalgia as Research Concept of Communication History: The Possible Research Perspectives

    Directory of Open Access Journals (Sweden)

    Nataša Simeunović Bajić

    2016-02-01

    Full Text Available Yugoslavia no longer exists. There is only yugonostalgia i.e. nostalgia for all those things which are no longer in common state boundaries. There remains common corpus of historical memory which is imposed to researchers as a good basis for affirmation. After the tragic decomposition of Yugoslavia, nationalist tendencies, interruption of communication channels and national reawakening in all former republics, the period of transition has arrived. But in the minds of ordinary people, political, economical and social changes have not brought long-expected "better life". Therefore more and more collective memory of everyday life, culture and social relations in the former Yugoslavia was revitalized. Yugonostalgia for a Yugoslav Union that no longer exists as a concept of studying the history of communication, can contribute to better understanding of the past and the future. For this reason, this paper attempts to explore the role of the concept of yugonostalgia as an important factor in studying the history of communication in the Yugoslav and post-Yugoslav context.

    2013-01-01

    For the formation of three microsatellites which fly in the same orbit and perform three-dimensional solid mapping for terra, this paper proposes an optimizing design method of space circular formation order based on improved generic algorithm and provides an intersatellite direct spread spectrum communication system. The calculating equation of LEO formation flying satellite intersatellite links is guided by the special requirements of formation-flying microsatellite intersatellite links, and the transmitter power is also confirmed throughout the simulation. The method of space circular formation order optimizing design based on improved generic algorithm is given, and it can keep formation order steady for a long time under various absorb impetus. The intersatellite direct spread spectrum communication system is also provided. It can be found that, when the distance is 1 km and the data rate is 1 Mbps, the input wave matches preferably with the output wave. And LDPC code can improve the communication performance. The correct capability of (512, 256) LDPC code is better than (2, 1, 7) convolution code, distinctively. The design system can satisfy the communication requirements of microsatellites. So, the presented method provides a significant theory foundation for formation-flying and intersatellite communication.

    Full Text Available Digital media and network communication technology have not changed this setup, but rather have opened the possibility for encountering and experiencing additional types of worlds and performing additional types of spatial practices. Being situated online and being globally networked with the possibility of both synchronous and asynchronous communication, digitally mediated worlds provide possible interactions between users which are radically more independent of time and place than the ones facilitated by older media. From this perspective, the concept of online worlds both challenges and broadens our understanding of how media shape the world and how the media technology creates new social structures.

    2014-05-01

    Since 2009 the Istituto Nazionale di Geofisica e Vulcanologia (INGV) participates to the European Researchers' Night, promoted by the European Commission, in the framework of Associazione Frascati Scienza (http://www.frascatiscienza.it/), with a program rich of events aimed at intriguingnand stimulating audiences of all ages about Earth Sciences, i.e., to make the general public aware on activities and roles of INGV researchers. For the September 27th Night, INGV contributed with a program in the INGV headquarters inspired by the INGV ScienzAperta Open Day held in April: guided tours, as well seminars held by researchers, exhibitions, educational games. We proposed two parallel programs: one devoted to earthquakes, including the visit to the INGV seismic surveillance room, seminars about Italian territory seismic hazard and exhibitions on Earthquakes and Volcanoes; the alternative program included the guided tour of the INGV laboratories (Aero-photogrammetry, Paleo-magnetism beside exhibition on geomagnetism, High Pressures and High Temperatures, Geochemistry, Restoration of historical instruments). In Frascati, we organized educational games, hands-on laboratories and a science theatre performance: "When the sky flashed red", as well as exhibitions at Museo Geofisico Rocca di Papa. A paper-based appreciation survey, compiled by visitors at INGV headquarter and by the scientific theatre's audiences, supplied our team with feedback, revealing some precious hints about users themselves, appreciation and margins of improvement, both in organization and in content. People of all ages and professions came. For example, a father asked specific paths for children, with even more appropriate language. A boy (aged 11) found the visit to the labs "interesting but a bit boring". It was suggested to prepare specific hand-outs for each visit, and certificates of participation for students. A girl, 9 years old, wrote that such event makes her closer to science world. The

    Sanz Merino, Noemí; Tarhuni Navarro, Daniela H

    2018-06-01

    This study aims to explore the perceptions and attitudes toward Public Communication of Science and Technology of the researchers of the National Council of Science and Technology (Conacyt), in order to provide a diagnosis about the ways the Mexican scientists are involved in public communication and to contribute to the visibility of researchers' needs in being able to popularize science. The results show significant differences among the researchers' opinions with respect to their perceptions about science communication, the ways they participate in PUS activities and their identified needs. In general, the researchers of Conacyt perceived public communication as very important. However, lack of time and of academic recognition stood out as determining factors in their low contribution to science popularization. We conclude that, to achieve a culture of Public Engagement in public communication of science and technology among R&D institutions, the Mexican Administration should address the above-mentioned unfavorable professional circumstances.

    2006-01-01

    Over the last three decades photodynamic therapy (PDT) has been developed to a useful clinical tool, a viable alternative in the treatment of cancer and other diseases. Several disciplines have contributed to this development: chemistry in the development of new photosensitizing agents, biology in the elucidation of cellular processes involved in PDT, pharmacology and physiology in identifying the mechanisms of distribution of photosensitizers in an organism, and, last but not least, physics in the development of better light sources, dosimetric concepts and construction of imaging devices, optical sensors and spectroscopic methods for determining sensitizer concentrations in different tissues. Physics and biophysics have also helped to focus on the role of pH for sensitizer accumulation, dose rate effects, oxygen depletion, temperature, and optical penetration of light of different wavelengths into various types of tissue. These are all important parameters for optimally effective PDT. The present review will give a brief, physically based, overview of PDT and then discuss some of the main biophysical aspects of this therapeutic modality.

  3. Microwave Tissue Ablation: Biophysics, Technology and Applications

    Science.gov (United States)

    2010-01-01

    Microwave ablation is an emerging treatment option for many cancers, cardiac arrhythmias and other medical conditions. During treatment, microwaves are applied directly to tissues to produce rapid temperature elevations sufficient to produce immediate coagulative necrosis. The engineering design criteria for each application differ, with individual consideration for factors such as desired ablation zone size, treatment duration, and procedural invasiveness. Recent technological developments in applicator cooling, power control and system optimization for specific applications promise to increase the utilization of microwave ablation in the future. This article will review the basic biophysics of microwave tissue heating, provide an overview of the design and operation of current equipment, and outline areas for future research for microwave ablation.

    2017-01-01

    Multiple studies have documented major limitations in the informed consent process for the recruitment of clinical research participants. One challenging aspect of this process is successful communication of risks and benefits to potential research participants. This study explored the opinions and attitudes of informed consent experts about conveying risks and benefits to inform the development of a survey about the perspectives of research nurses who are responsible for obtaining informed consent for clinical trials. The major themes identified were strategies for risks and benefits communication, ensuring comprehension, and preparation for the role of the consent administrator. From the experts’ perspective, inadequate education and training of the research staff responsible for informed consent process contribute to deficiencies in the informed consent process and risks and benefits communication. Inconsistencies in experts’ opinions and critique of certain widely used communication practices require further consideration and additional research. PMID:28975139

    Full Text Available The Sunda Banda Seascape (SBS, located in the center of the Coral Triangle, is a global center of marine biodiversity and a conservation priority. We proposed the first biophysical environmental delineation of the SBS using globally available satellite remote sensing and model-assimilated data to categorize this area into unique and meaningful biophysical classes. Specifically, the SBS was partitioned into eight biophysical classes characterized by similar sea surface temperature, chlorophyll a concentration, currents, and salinity patterns. Areas within each class were expected to have similar habitat types and ecosystem functions. Our work supplemented prevailing global marine management schemes by focusing in on a regional scale with finer spatial resolution. It also provided a baseline for academic research, ecological assessments and will facilitate marine spatial planning and conservation activities in the area. In addition, the framework and methods of delineating biophysical environments we presented can be expanded throughout the whole Coral Triangle to support research and conservation activities in this important region.

  11. Research on the influence that communication in psychiatric encounters has on treatment.

    Science.gov (United States)

    Cruz, Mario; Pincus, Harold Alan

    2002-10-01

    The purpose of this article is to inform mental health professionals about the empirical literature on medical and psychiatric encounters and the influence of communicative behaviors on specific encounter outputs and treatment outcomes. A comprehensive review of the health communications literature from 1950 to 2001, using MEDLINE and PsycINFO, was conducted to identify relevant articles on the communication skills of psychiatrists and other physicians. These searches were augmented by personal correspondence with experts on changes in practice patterns in psychiatry and on medical and psychiatric communications research. A review of references within each article and information from the experts identified other relevant articles. Selection was then narrowed to include reports of studies that used structured written instruments that captured relevant physician and patient perceptions of the physician-patient relationship, content analysis of audio- or videotapes of communication in medical or psychiatric encounters, or interaction analysis systems used to categorize audio- or videotaped communicative behaviors in medical or psychiatric encounters. Twenty-five articles in medicine and 34 articles in psychiatry were selected. Medical communication researchers have observed associations between physicians' communicative skills and patients' satisfaction, patients' adherence to treatment recommendations, treatment outputs, and patients' willingness to file malpractice claims. The research has also shown that primary care physicians can be more responsive to patients' concerns without lengthening visits. In psychiatry, the literature can be organized into four discrete categories of research: negotiated treatment and the customer approach, therapeutic alliance, Gottschalk-Gleser content analysis of patients' speech, and content analysis of psychiatric interviews.

    Akerlof, K.; Johnson, B. B.; Nackerman, C. J.; Maibach, E.

    2014-12-01

    Climate change represents the worst of wicked environmental problems, requiring collaborations among individuals and groups that cross public, private and voluntary sectors on a global scale to reduce greenhouse gas emissions and prepare for impacts. The Climate Communication Consortium of Maryland represents such a collaboration on a state level for the purpose of supporting governments, non-profits, businesses and universities in communicating with the public about climate and energy within the context of multiple frames, such as public health, extreme weather, and coastal resilience. The collaboration was developed using communication research as an organizational framework - providing data from yearly public opinion surveys on Marylanders' attitudes, behaviors and policy support, and a variety of other qualitative and quantitative studies. In this presentation, we will highlight four dimensions of the use of research within collaborative organizational climate communication that can lead to success, or impediments: 1) individual organizational ability and resources for using audience data; 2) the linking of research questions to programmatic development goals and processes; 3) the weighing of audience- versus communicator-oriented values and priorities; and 4) identification of overarching communication objectives that span individual organizational interests. We will illustrate these dimensions using findings from surveys of our member organizations describing the types of barriers organizations face in communicating about climate change effectively, including their use of formative and evaluative research, and will discuss some of the findings from our public opinion and experimental research, illustrating the ways in which these findings influenced programmatic development and were used by Consortium member organizations.

    2018-01-01

    Macroscopic cellular structures and functions are generally investigated using biological and biochemical approaches. But these methods are no longer adequate when one needs to penetrate deep into the small-scale structures and understand their functions. The cell is found to hold various physical structures, molecular machines, and processes that require physical and mathematical approaches to understand and indeed manipulate them. Disorders in general cellular compartments, perturbations in single molecular structures, drug distribution therein, and target specific drug-binding, etc. are mostly physical phenomena. This book will show how biophysics has revolutionized our way of addressing the science and technology of nanoscale structures of cells, and also describes the potential for manipulating the events that occur in them.

    2017-10-23

    In any crisis, there is a great deal of uncertainty, often geographical uncertainty or, more precisely, spatiotemporal uncertainty. Examples include the spread of contamination from an industrial accident, drifting volcanic ash, and the path of a hurricane. Estimating spatiotemporal probabilities is usually a difficult task, but that is not our primary concern. Rather, we ask how analysts can communicate spatiotemporal uncertainty to those handling the crisis. We comment on the somewhat limited literature on the representation of spatial uncertainty on maps. We note that many cognitive issues arise and that the potential for confusion is high. We note that in the early stages of handling a crisis, the uncertainties involved may be deep, i.e., difficult or impossible to quantify in the time available. In such circumstance, we suggest the idea of presenting multiple scenarios. © 2017 Society for Risk Analysis.

  4. What conceptions of science communication are espoused by science research funding bodies?

    Science.gov (United States)

    Palmer, Sarah E; Schibeci, Renato A

    2014-07-01

    We examine the conceptions of science communication, especially in relation to "public engagement with science" (PES), evident in the literature and websites of science research funding bodies in Europe, North America, South America, Asia and Oceania, and Africa. The analysis uses a fourfold classification of science communication to situate these conceptions: professional, deficit, consultative and deliberative. We find that all bodies engage in professional communication (within the research community); however, engagement with the broader community is variable. Deficit (information dissemination) models still prevail but there is evidence of movement towards more deliberative, participatory models.

  5. Cross-Cultural Communication Training for Students in Multidisciplinary Research Area of Biomedical Engineering

    Directory of Open Access Journals (Sweden)

    2014-08-01

    Full Text Available Biomedical Engineering makes multidisciplinary research area, which includes biology, medicine, engineering and others. Communication training is important for students, who have a potential to develop Biomedical Engineering. Communication is not easy in a multidisciplinary research area, because each area has its own background of thinking. Because each nation has its own background of culture, on the other hand, international communication is not easy, either. A cross-cultural student program has been designed for communication training in the multidisciplinary research area. Students from a variety of backgrounds of research area and culture have joined in the program: mechanical engineering, material science, environmental engineering, science of nursing, dentist, pharmacy, electronics, and so on. The program works well for communication training in the multidisciplinary research area of biomedical engineering. Foreign language and digital data give students chance to study several things: how to make communication precisely, how to quote previous data. The experience in the program helps students not only understand new idea in the laboratory visit, but also make a presentation in the international research conference. The program relates to author's several experiences: the student internship abroad, the cross-cultural student camp, multi PhD theses, various affiliations, and the creation of the interdisciplinary department.

  14. Exploring risk communication - results of a research project focussed on effectiveness evaluation

    Science.gov (United States)

    Charrière, Marie; Bogaard, Thom; Junier, Sandra; Mostert, Erik

    2016-04-01

    The need for effective science communication and outreach efforts is widely acknowledged in the academic community. In the field of Disaster Risk Reduction, the importance of communication is clearly stressed, e.g. in the newly adopted Sendai Framework for Disaster Risk Reduction 2015-2030 (under the 1st priority of action: understanding disaster risk). Consequently, we see increasing risk communication activities. However, the effectiveness of these activities is rarely evaluated. To address this gap, several research activities were conducted in the context of the Marie Curie Initial Training Network "Changes", the results of which we will present and discuss. First, results of a literature review show, among others, that research on effectiveness is mainly focussed on the assessment of users' needs and their ability to understand the content, rather than on the final impact of the risk communication efforts. Moreover, lab-environment research is more often undertaken than assessment of real communication efforts. Second, a comparison between perceptions of risk managers and the general public of risk communication in a French Alps Valley highlighted a gap between the two groups in terms of amount of information needed (who wants more), the important topics to address (what) and the media to use (how). Third, interviews with developers of smartphone applications for disseminating avalanche risk information showed a variety of current practices and the absence of measurements of real their effectiveness. However, our analysis allowed identifying good practices that can be an inspiration for risk communication related to other hazards. Fourth, an exhibition has been set up following a collaborative approached based on stakeholder engagement. Using a pre/post-test design, the immediate impact of the exhibition, which aimed at increasing the risk awareness of the population (Ubaye Valley, France), was measured. The data obtained suggests that visiting the exhibition

  20. The evolving concept of "patient-centeredness" in patient-physician communication research.

    Science.gov (United States)

    Ishikawa, Hirono; Hashimoto, Hideki; Kiuchi, Takahiro

    2013-11-01

    Over the past few decades, the concept of "patient-centeredness" has been intensively studied in health communication research on patient-physician interaction. Despite its popularity, this concept has often been criticized for lacking a unified definition and operationalized measurement. This article reviews how health communication research on patient-physician interaction has conceptualized and operationalized patient-centered communication based on four major theoretical perspectives in sociology (i.e., functionalism, conflict theory, utilitarianism, and social constructionism), and discusses the agenda for future research in this field. Each theory addresses different aspects of the patient-physician relationship and communication from different theoretical viewpoints. Patient-centeredness is a multifaceted construct with no single theory that can sufficiently define the whole concept. Different theoretical perspectives of patient-centered communication can be selectively adopted according to the context and nature of problems in the patient-physician relationship that a particular study aims to explore. The present study may provide a useful framework: it offers an overview of the differing models of patient-centered communication and the expected roles and goals in each model; it does so toward identifying a communication model that fits the patient and the context and toward theoretically reconstructing existing measures of patient-centered communication. Furthermore, although patient-centered communication has been defined mainly from the viewpoint of physician's behaviors aimed at achieving patient-centered care, patient competence is also required for patient-centered communication. This needs to be examined in current medical practice. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Full Text Available Objective of the research described in this article is to make an analysis of the usage of marketing communication using both traditional Internet communication channels as well as Social Media Networks by the Czech companies. Primary research was made through on-line questionnaire. Companies across the branches and size categories within the Czech economy were addressed. Companies were selected from the www.firmy.cz portal. Only companies with their own web domain were addressed. The typical respondents were mostly from middle management, especially managers from the marketing or commercial departments. The final number of questionnaire respondents covered in the research is 1009. The main research method was questioning. The questionnaire consisted of three sections with the scale answer questions mainly. Google Refine was used for data processing and Microsoft Excel for statistical processing and graphic outputs of the research. Evaluated results show significant gaps in usage of Internet communication tools in marketing of Czech companies and also deficiency between clear understanding of the respondents how Social Media should be used in marketing communication and real use in the companies. This deficiency was statistically tested and relation between respondents’ perception of the importance of Social Media use for bidirectional communication with stakeholders and non-use of Social Media for bidirectional communication with stakeholders by respondents’ company was confirmed.

  6. Historical and Critical Review on Biophysical Economics

    Science.gov (United States)

    Adigüzel, Yekbun

    2016-07-01

    Biophysical economics is initiated with the long history of the relation of economics with ecological basis and biophysical perspectives of the physiocrats. It inherently has social, economic, biological, environmental, natural, physical, and scientific grounds. Biological entities in economy like the resources, consumers, populations, and parts of production systems, etc. could all be dealt by biophysical economics. Considering this wide scope, current work is a “biophysical economics at a glance” rather than a comprehensive review of the full range of topics that may just be adequately covered in a book-length work. However, the sense of its wide range of applications is aimed to be provided to the reader in this work. Here, modern approaches and biophysical growth theory are presented after the long history and an overview of the concepts in biophysical economics. Examples of the recent studies are provided at the end with discussions. This review is also related to the work by Cleveland, “Biophysical Economics: From Physiocracy to Ecological Economics and Industrial Ecology” [C. J. Cleveland, in Advances in Bioeconomics and Sustainability: Essay in Honor of Nicholas Gerogescu-Roegen, eds. J. Gowdy and K. Mayumi (Edward Elgar Publishing, Cheltenham, England, 1999), pp. 125-154.]. Relevant parts include critics and comments on the presented concepts in a parallelized fashion with the Cleveland’s work.

  7. Building biophysics in mid-century China: the University of Science and Technology of China.

    Science.gov (United States)

    Luk, Yi Lai Christine

    2015-01-01

    Biophysics has been either an independent discipline or an element of another discipline in the United States, but it has always been recognized as a stand-alone discipline in the People's Republic of China (PRC) since 1949. To inquire into this apparent divergence, this paper investigates the formational history of biophysics in China by examining the early institutional history of one of the best-known and prestigious science and technology universities in the PRC, the University of Science and Technology of China (USTC). By showing how the university and its biophysics program co-evolved with national priorities from the school's founding in 1958 to the eve of the Cultural Revolution in 1966, the purpose of this paper is to assess the development of a scientific discipline in the context of national demands and institutional politics. Specific materials for analysis include the school's admission policies, curricula, students' dissertations, and research program. To further contextualize the institutional setting of Chinese biophysics, this paper begins with a general history of proto-biophysical institutions in China during the Nationalist-Communist transitional years. This paper could be of interest to historians wanting to know more about the origin of the biophysics profession in China, and in particular how research areas that constitute biophysics changed in tandem with socio-political contingencies.

    Social networks enable anyone to publish potentially boundless amounts of information. However, such information is also highly prone to creating and/or diffusing mistakes and misunderstandings in scientific issues. In 2013 we produced a website (www.sunability.unina2.it) reporting on some research outputs from the University of Campania Luigi Vanvitelli (formerly the Second University of Naples, SUN), and shared it on Facebook and Twitter to analyse the effectiveness of these platforms in scientific dissemination. The study results suggest that (i) a regular update of the website stimulates the user's interest, (ii) Campania's citizens are more concerned with pollution problems than natural hazards, and (iii) direct involvement of researchers effectively enhances web-mediated scientific dissemination.

    2015-11-01

    This study attempted to illuminate the cause and relation between government, scholars, disciplines, and societal aspects, presenting data from a content analysis of published research with the key word "science communication" (Symbol: see text) in the title or in the key words, including academic papers published in journals and dissertations from the China National Knowledge Infrastructure database. Of these, 572 articles were coded using categories that identified science topics, theory, authorship, and methods used in each study to examine the breadth and depth that Science Communication has achieved since its inception in China. This study explored the dominance of History and Philosophy of Science scholars rather than Communication scholars. We also explored how science communication research began from theories and concepts instead of science report analysis and the difficulties of the shift from public understanding of science to public engagement in China. © The Author(s) 2015.

    Taguchi, Masamichi

    The Science and Technology Agency constructed a PC-based communication network system named 'The Tsukuba Network' as a new medium for promoting the research communication in, and with, the Tsukuba City. For about a year prior to full operation, a pilot system was operated with the cooperation of some monitoring users to gain skill and experience for managing the PC-based communication network. The main service functions of the system are : bulletin board service; electronic mail ; construction of, and access to, the databases involving research information in Tsukuba City ; electronic conference; common use of softwares ; connection to other communication networks ( e.g., university and local network). The host computer is a work station EWS4800 and the network processor is a personal computer PC-9801 . These two computers are connected with LAN.

  14. Communication in superconductivity research: A study of scientific discoveries with particular reference to a developing country

    Chu, H.

    1991-01-01

    The main objective is to study the communications dimensions of China's contribution to the discovery of high-Tc superconductors. Chinese researchers of the field were compared with non-Chinese superconductivity scientists from developed countries to reveal similarities and differences in the formal as well as the informal domains of scholarly communication. 240 documents highly cited in a manually created Chinese data base and in Science Citation Index for the period of 1987-89 were examined to delineate the formal structure of communication in the area. Noteworthy similarities, e.g., similar cited cores, identical publication sources, and comparable intellectual structures of cocitation data, were found in formal communication between Chinese and non-Chinese scientists. Nevertheless, differences were also located in regard to citedness, timeliness and direction of communication. Findings reflect the role Chinese scientists played in the discovery of high-Tc superconductors. Chinese researchers overall did better in the formal domain than in the informal realm of scientific communication. Informal communication with scientists from advanced nations appears to be a very weak element in China's endeavors of searching for high-Tc superconductors

    This study systematically located and appraised peer-reviewed evidence for the efficacy of strategies to increase organ donation decision communication among adults including an assessment of study quality to guide future research in this field. There is little room to move in strengthening unanimously positive public attitudes toward organ donation. Consequently, researchers have called for a focus on organ donation decision communication to understand modifiable factors to increase organ donation rates. Multiple databases were searched during September 2015, and 44 studies were selected for inclusion. Data concerning participants, design, and outcomes were extracted. Studies were rated for quality and levels of evidence. Although not amenable to meta-analysis, the literature indicates that approximately 50% of adults who are willing to become an organ donor have discussed this decision with family. The majority of research was conducted in a Western context with an overrepresentation of students. Strategies to increase communication include education, motivation, input from lived experience, efforts to address salient audience beliefs, and scheduled reminders or prompts. Intentions and willingness to discuss organ donation were consistently positively related to discussion behavior; however, formative research and experimental studies testing theoretically driven interventions were scarce. There is mixed evidence for the role of demographic and attitudinal characteristics in the success of organ donation communication interventions. Additional theoretically based research is recommended to establish boundary conditions and validate strategies to increase organ donation decision communication among adults.

    2011-03-01

    Difficulties with memory and communication are prominent and distressing features of dementia which impact on the person with dementia and contribute to caregiver stress and burden. There is a need to provide caregivers with strategies to support and maximize memory and communication abilities in people with dementia. In this project, a team of clinicians, researchers and educators in neuropsychology, psychogeriatrics, nursing and speech pathology translated research-based knowledge from these fields into a program of practical strategies for everyday use by family and professional caregivers. From the available research evidence, the project team identified compensatory or facilitative strategies to assist with common areas of difficulty, and structured these under the mnemonics RECAPS (for memory) and MESSAGE (for communication). This information was adapted for presentation in a DVD-based education program in accordance with known characteristics of effective caregiver education. The resultant DVD comprises (1) information on the nature and importance of memory and communication in everyday life; (2) explanations of common patterns of difficulty and preserved ability in memory and communication across the stages of dementia; (3) acted vignettes demonstrating the strategies, based on authentic samples of speech in dementia; and (4) scenarios to prompt the viewer to consider the benefits of using the strategies. Using a knowledge-translation framework, information and strategies can be provided to family and professional caregivers to help them optimize residual memory and communication in people with dementia. Future development of the materials, incorporating consumer feedback, will focus on methods for enabling wider dissemination.

    Full Text Available The diagnostic phase of an interactive research evaluation model was used in the investigation of the animal welfare needs of a low-income urban community in South Africa. Data were gathered by means of a structured interview and direct observations by animal welfare officers. During the survey of 871 animal owners in Soweto, it was found that dogs were owned by 778 households and cats by 88 households. The dog to human ratio was estimated at 1:12.4. Respondents were asked whether they enjoyed owning animals and 96.1 % said that they did. Only 26.3 % mentioned that they had problems with their own animals and 16.6 % had problems with other people's animals. Treatment of sick animals (29.7 % was seen as a priority. However, less than 1 % (n = 6 used the services of private veterinarians. Others took their animals to welfare organisations or did not have them treated. Perceptions of affordable costs of veterinary treatments were also recorded. In addition to treatment, respondents indicated a need for vaccination (22.5 %, sterilisation (16.5 %, control of internal (3.7 % and external (8.8 % parasites, education and extension (6.6 %, prevention of cruelty to animals (3.2 % and expansion of veterinary clinics to other parts of Soweto (1.3 %.

  12. Communication among scientists, decision makers and society: Developing policy-relevant global climate change research

    International Nuclear Information System (INIS)

    Bernabo, J.C.

    1995-01-01

    Defining the research most relevant to policy is not simply a technical task that can be answered by scientists. Decision makers need and value information differently than curiosity-driven scientists. In order to link science more effectively to policy, the two communities must gain a greater mutual understanding. Decision makers must define their needs so that scientists can determine how, and by when, research can address these needs. This vital dialogue between communities typically has been more ad hoc than systematic. The complexity and urgency of the global climate change issue necessitate ongoing communication between scientists and decision makers on the information needed for policy development and what research can provide The results of relevant science policy dialogues are discussed herein. Effective communication between researchers and decision makers is a crucial ingredient for successfully addressing society's pressing environmental concerns. The increase in policy makers' demands for research that is relevant to solving societal issues highlights the communication gap between the technical and policy communities. The gap, largely caused by lack of mutual understanding, results in flawed and inadequate communication that hinders decision making and confuses the public. This paper examines the cause of this communication gap and describes the significance of recent efforts to develop more fruitful science-policy dialogues on the issue of global climate change. First, the post-Cold War shift in government priorities for research funding is described; then the underlying relationship between science and policy is explored to identify key sources of ongoing mis-communication. The paper then explains the importance of defining policy-relevant science questions that research can address. Finally, three projects are described involving the elicitation of decision makers' information needs in The United States, The Netherlands, and internationally

    2017-06-01

    Full Text Available Communication research in Asia has enjoyed rapid growth in the 20th century amid Asia’s economic boom, rapid growth in communication technologies and expanded university faculty. To explore the extent to which the rise of Asian communication research continued in the 21st century, a total of 558 publications on Asian communication research in 14 top-ranked SSCI communication journals from 1995 to 2014 were analyzed. Results indicate that the rise of Asian communication research is afoot in the 21st century. However, the results of also suggest patterns of unevenness of the published scholarship in terms of publishing year, journals, region, research topics and methodology: Asian communication research was dominated by East Asia, which was dominated by China, South Korea and Japan; in terms of research areas by topic, Asian communication scholarship focused on a few areas, including media effects, political communication, communication technology, and health communication; in terms of research methodologies, the quantitative approach was found to be dominant in the publications, which accounts for more than twice that of qualitative research.

    As it has done in the past, NASA is currently engaged in furthering the frontiers of space and planetary exploration. The effectiveness in gathering the desired science data in the amount and quality required to perform this pioneering work relies heavily on the communications capabilities of the spacecraft and space platforms being considered to enable future missions. Accordingly, the continuous improvement and development of radiofrequency and optical communications systems are fundamental to prevent communications to become the limiting factor for space explorations. This presentation will discuss some of the research and technology development efforts currently underway at the NASA Glenn Research Center in the radio frequency (RF) and Optical Communications. Examples of work conducted in-house and also in collaboration with academia, industry, and other government agencies (OGA) in areas such as antenna technology, power amplifiers, radio frequency (RF) wave propagation through Earths atmosphere, ultra-sensitive receivers, thin films ferroelectric-based tunable components, among others, will be presented. In addition, the role of these and other related RF technologies in enabling the NASA next generation space communications architecture will be also discussed.

    2011-12-01

    Phenology plays a key role in the environment and ecosystem. Primary and secondary students around the world have been collecting vegetation phenology data and contributing to ongoing scientific investigations. They have increased research capacity by increasing spatial coverage of ground observations that can be useful for validation of remotely sensed data. The green-up and green-down phenology measurement protocols developed at the University of Alaska Fairbanks (UAF) as part of the Global Learning and Observations to Benefit the Environment (GLOBE) program, have been used in more than 250 schools in over 20 countries. In addition to contributing their data, students have conducted their own investigations and presented them at science fairs and symposiums, and international conferences. An elementary school student in Alaska conducted a comprehensive study on the green-down rates of native and introduced trees and shrubs. Her project earned her a one-year college scholarship at UAF. Students from the Model Secondary School for the Deaf in Washington, D. C. and from the Indiana School for the Deaf collaborated on a comparative green-up study, and were chosen to present at an international conference where students from more than 20 countries participated. Similarly, students in Thailand presented at national conferences, their studies such as "The Relationship between Environmental Conditions and Green-down of Teak Trees (Tectona grandis L.)" at Roong Aroon School, Bangkok and "The Comparison of Budburst and Green-up of Leab Trees (Ficus infectoria Roxb.) at Rob Wiang and Mae Khao Tom Sub-district in Chiang Rai Province". Some challenges in engaging students in phenological studies include the mismatch in timing of the start and end of the plant growing season with that of the school year in northern latitudes and the need for scientists and teachers to work with students to ensure accurate measurements. However these are outweighed by benefits to the scientists

    Beaven, S.

    2015-12-01

    Disasters stimulate research activity by creating comparatively rare post-disaster data, while also increasing the urgency of agency demand for scientific evidence. In the wake of the 2011 Christchurch Earthquake disaster, New Zealand, post-disaster research activity was coordinated by a national Natural Hazards Research Platform, in collaboration with response agencies. The focus was on research support for responding agencies, with an emphasis on creating high quality scientific outcomes. This coordinated research effort did not include independent research activity, which escalated steeply in the weeks after the event. The risks this increased research pressure posed to response operations and impacted populations informed the declaration of a moratorium on research not deemed relevant to the needs of response agencies. This presentation summarizes communication issues that made it difficult to disseminate the moratorium, and to establish the relevance of this decision where it might have been most effective in diminishing these risks: within national and international natural hazard and disaster research communities, other national research communities, across responding agencies and organisations, and among impacted organizations and communities.

  18. A History of the Western Institute of Nursing and Its Communicating Nursing Research Conferences.

    McNeil, Paula A; Lindeman, Carol A

    The Western Institute of Nursing (WIN) celebrated its 60th anniversary and the 50th Annual Communicating Nursing Research Conference in April 2017. The purpose of this article is to provide a brief history of the origin, development, and accomplishments of WIN and its Communicating Nursing Research conferences. Historical documents and conference proceedings were reviewed. WIN was created in 1957 as the Western Council on Higher Education for Nursing under the auspices of the Western Interstate Commission for Higher Education. The bedrock and enduring value system of the organization is the interrelated nature of nursing education, practice, and research. There was a conviction that people in the Western region of the United States needed nursing services of excellent quality and that nursing education must prepare nurses capable of providing that care. Shared goals were to increase the science of nursing through research and to produce nurses who could design, conduct, and supervise research-all to the end of improving quality nursing care. These goals were only achieved by collaboration and resource sharing among the Western region states and organizations. Consistent with the goals, the first research conferences were held between 1957 and 1962. Conference content focused on seminars for faculty teaching research, on the design and conduct of research in patient care settings, and on identification of priority areas for research. The annual Communicating Nursing Research conferences began in 1968 and grew over the years to a total 465 podium and poster presentations on a wide array of research topics-and an attendance of 926-in 2016. As WIN and its Communicating Nursing Research conferences face the next 50 years, the enduring values on which the organization was created will stand in good stead as adaptability, adjustments, and collaborative effort are applied to inevitable change for the nursing profession. It is the Western way.

    Augmentative and alternative communication (AAC) social media research is relatively new, and is built on a foundation of research on use of the Internet and social media by people with communication disabilities. Although the field is expanding to include a range of people who use AAC, there are limitations and gaps in research that will need to be addressed in order to keep pace with the rapid evolution of social media connectivity in assistive communication technologies. In this paper, we consider the aims, scope, and methodologies of AAC social media research, with a focus on social network sites. Lack of detailed attention to specific social network sites and little use of social media data limits the extent to which findings can be confirmed. Increased use of social media data across a range of platforms, including Instagram and YouTube, would provide important insights into the lives of people who use AAC and the ways in which they and their supporters use social media. New directions for AAC social media research are presented in line with those discussed at the social media research symposium at the International Society for Augmentative and Alternative Communication in Toronto, Canada, on August 12, 2016.

    The field of structural bioinformatics and computational biophysics has undergone a revolution in the last 10 years. Developments that are captured annually through the 3DSIG meeting, upon which this article reflects. An increase in the accessible data, computational resources and methodology has resulted in an increase in the size and resolution of studied systems and the complexity of the questions amenable to research. Concomitantly, the parameterization and efficiency of the methods have markedly improved along with their cross-validation with other computational and experimental results. The field exhibits an ever-increasing integration with biochemistry, biophysics and other disciplines. In this article, we discuss recent achievements along with current challenges within the field. © The Author 2014. Published by Oxford University Press.

  1. Conducting research in risk communication that is both beneficial for stakeholders and scientists

    2015-04-01

    One of the key tasks for disaster risk reduction is raising awareness. On way to increase it is through risk communication, including visual risk communication. Previous research showed that visual risk communication linked to natural hazards is mostly evaluated in terms of user's requirements, ability to understand the content, or satisfaction with the diverse components of the tool(s): Its impact on risk awareness is not researched. Most of the risk communication evaluations are performed in a lab-type environments and thus their conclusions might not be fully valid in real life settings. Our approach differs in the sense that we decided to test a real communication effort. However, we did not use an existing one but designed our own. This process was conducted according to collaborative research principles, meaning that we created the communication effort in collaboration with the local stakeholders in order to respect the social environment of the case study. Moreover, our research activity should be beneficial and significant for the community in which we work as well as for science. This contribution will present the process that allowed us to design an exhibition in the Ubaye Valley (France) and the methodology that was developed to measure changes in risk awareness. During a 2-years project, we collaborated with local and regional stakeholders (politicians and technicians). Informal meetings with local stakeholders were organized to determine what they perceived as the needs in term of risk communication and to investigate the potential to develop activities that would benefit both them and us. We were offered the opportunity to design an exhibition for the local public library. We proposed the content and this was adjusted in interaction with the stakeholders.

    2010-07-01

    Astronomers are ever dreaming of sites with best seeing on the Earth surface for celestial observation, and the Antarctica is one of a few such sites only left owing to the global air pollution. However, Antarctica region is largely unaccessible for human being due to lacking of fundamental living conditions, travel facilities and effective ways of communication. Worst of all, the popular internet source as a general way of communication scarcely exists there. Facing such a dilemma and as a solution remote control and data transmission for telescopes through iridium satellite communication has been put forward for the Chinese network Antarctic Schmidt Telescopes 3 (AST3), which is currently under all round research and development. This paper presents iridium satellite-based remote control application adapted to telescope control. The pioneer work in China involves hardware and software configuration utilizing techniques for reliable and secure communication, which is outlined in the paper too.

    Increasing audience knowledge is often set as a primary objective of risk communication efforts. But is it worthwhile focusing risk communication strategies solely on enhancing specific knowledge? The main research questions tackled in this paper were: (1) if prior audience knowledge related to specific radiation risks is influential for the perception of these risks and the acceptance of communicated messages and (2) if gender, attitudes, risk perception of other radiation risks, confidence in authorities, and living in the vicinity of nuclear/radiological installations may also play an important role in this matter. The goal of this study was to test empirically the mentioned predictors in two independent case studies in different countries. The first case study was an information campaign for iodine pre-distribution in Belgium (N = 1035). The second was the information campaign on long-term radioactive waste disposal in Slovenia (N = 1,200). In both cases, recurrent and intensive communication campaigns were carried out by the authorities aiming, among other things, at increasing specific audience knowledge. Results show that higher prior audience knowledge leads to more willingness to accept communicated messages, but it does not affect people’s perception of the specific risk communicated. In addition, the influence of prior audience knowledge on the acceptance of communicated messages is shown to be no stronger than that of general radiation risk perception. The results in both case studies suggest that effective risk communication has to focus not only on knowledge but also on other more heuristic predictors, such as risk perception or attitudes toward communicated risks.

  8. The communication of forensic science in the criminal justice system: A review of theory and proposed directions for research.

    Howes, Loene M

    2015-03-01

    Clear communication about forensic science is essential to the effectiveness and perceived trustworthiness of the criminal justice system. Communication can be seen as a meaning-making process that involves different components such as the sender of a message, the message itself, the channel in which a message is sent, and the receiver of the message. Research conducted to date on the communication between forensic scientists and non-scientists in the criminal justice system has focused on different components of the communication process as objects of study. The purpose of this paper is to bring together communication theory and past research on the communication of forensic science to contribute to a deeper understanding of it, and to provide a coherent view of it overall. The paper first outlines the broader context of communication theory and science communication as a backdrop to forensic science communication. Then it presents a conceptual framework as a way to organise past research and, using the framework, reviews recent examples of empirical research and commentary on the communication of forensic science. Finally the paper identifies aspects of the communication of forensic science that may be addressed by future research to enhance the effectiveness of communication between scientists and non-scientists in this multidisciplinary arena.

    2015-12-01

    Interpreting and communicating water issues in an era of exponentially increasing information requires a blend of domain expertise, computational proficiency, and communication skills. The USGS Office of Water Information has established a Data Science team to meet these needs, providing challenging careers for diverse domain scientists and innovators in the fields of information technology and data visualization. Here, we detail the experience of building a Data Science capability as a bridging element between traditional water resources analyses and modern computing tools and data management techniques. This approach includes four major components: 1) building reusable research tools, 2) documenting data-intensive research approaches in peer reviewed journals, 3) communicating complex water resources issues with interactive web visualizations, and 4) offering training programs for our peers in scientific computing. These components collectively improve the efficiency, transparency, and reproducibility of USGS data analyses and scientific workflows.

    Objective To identify research priorities of consumers and other stakeholders to inform Cochrane Reviews in ‘health communication and participation’ (including such concepts as patient experience, shared decision-making and health literacy). Setting International. Participants We included anyone with an interest in health communication and participation. Up to 151 participants (18–80 years; 117 female) across 12 countries took part, including 48 consumers (patients, carers, consumer representatives) and 75 professionals (health professionals, policymakers, researchers) (plus 25 people who identified as both). Design Survey. Methods We invited people to submit their research ideas via an online survey open for 4 weeks. Using inductive thematic analysis, we generated priority research topics, then classified these into broader themes. Results Participants submitted 200 research ideas, which we grouped into 21 priority topics. Key research priorities included: insufficient consumer involvement in research (19 responses), ‘official’ health information is contradictory and hard to understand (18 responses), communication/coordination breakdowns in health services (15 responses), health information provision a low priority for health professionals (15 responses), insufficient eliciting of patient preferences (14 responses), health services poorly understand/implement patient-centred care (14 responses), lack of holistic care impacting healthcare quality and safety (13 responses) and inadequate consumer involvement in service design (11 responses). These priorities encompassed acute and community health settings, with implications for policy and research. Priority populations of interest included people from diverse cultural and linguistic backgrounds, carers, and people with low educational attainment, or mental illness. Most frequently suggested interventions focused on training and cultural change activities for health services and health professionals

    The day-to-day operators of today's aerospace systems work under increasing pressures to accomplish more with less. They work in operational systems which are complex, technology-based, and high-risk; in which incidents and accidents have far-reaching and costly consequences. For these and other reasons, there is concern that the safety net formerly built upon redundant systems and abundant resources may become overburdened. Although we know that human ingenuity can overcome incredible odds, human nature can also fail in unpredictable ways. Over the last 20 years, a large percentage of aviation accidents and incidents have been attributed to human errors rather than hardware or environmental factors alone. A class of errors have been identified which are not due to a lack of individual, technical competencies. Rather, they are due to the failure of teams to utilize readily available resources or information in a timely fashion. These insights began a training revolution in the aviation industry called Cockpit Resource Management, which later became known as Crew Resource Management (CRM) as its concepts and applications extended to teams beyond the flightdeck. Then, as now, communication has been a cornerstone in CRM training since crew coordination and resource management largely resides within information transfer processes--both within flightcrews, and between flightcrews and the ground operations teams that support them. The research I will describe takes its roots in CRM history as we began to study communication processes in order to discover symptoms of crew coordination problems, as well as strategies of effective crew management. On the one hand, communication is often the means or the tool by which team members manage their resources, solve problems, maintain situational awareness and procedural discipline. Conversely, it is the lack of planning and resource management, loss of vigilance and situational awareness, and non-standard communications that are

  8. Engineered biomaterial and biophysical stimulation as combinatorial strategies to address prosthetic infection by pathogenic bacteria.

    Science.gov (United States)

    Boda, Sunil Kumar; Basu, Bikramjit

    2017-10-01

    A plethora of antimicrobial strategies are being developed to address prosthetic infection. The currently available methods for implant infection treatment include the use of antibiotics and revision surgery. Among the bacterial strains, Staphylococcus species pose significant challenges particularly, with regard to hospital acquired infections. In order to combat such life threatening infectious diseases, researchers have developed implantable biomaterials incorporating nanoparticles, antimicrobial reinforcements, surface coatings, slippery/non-adhesive and contact killing surfaces. This review discusses a few of the biomaterial and biophysical antimicrobial strategies, which are in the developmental stage and actively being pursued by several research groups. The clinical efficacy of biophysical stimulation methods such as ultrasound, electric and magnetic field treatments against prosthetic infection depends critically on the stimulation protocol and parameters of the treatment modality. A common thread among the three biophysical stimulation methods is the mechanism of bactericidal action, which is centered on biophysical rupture of bacterial membranes, the generation of reactive oxygen species (ROS) and bacterial membrane depolarization evoked by the interference of essential ion-transport. Although the extent of antimicrobial effect, normally achieved through biophysical stimulation protocol is insufficient to warrant therapeutic application, a combination of antibiotic/ROS inducing agents and biophysical stimulation methods can elicit a clinically relevant reduction in viable bacterial numbers. In this review, we present a detailed account of both the biomaterial and biophysical approaches for achieving maximum bacterial inactivation. Summarizing, the biophysical stimulation methods in a combinatorial manner with material based strategies can be a more potent solution to control bacterial infections. © 2016 Wiley Periodicals, Inc.

    Evidence shows that territorial borders continue to have an impact on research collaboration in Europe. Knowledge of national research structural contexts is therefore crucial to the promotion of Europe-wide policies for research funding. Nevertheless, studies assessing and comparing research systems remain scarce. This paper aims to further the knowledge on national research landscapes in Europe, focusing on non-communicable disease (NCD) research in Italy and Germany. To capture the architecture of country-specific research funding systems, a three-fold strategy was adopted. First, a literature review was conducted to determine a list of key public, voluntary/private non-profit and commercial research funding organisations (RFOs). Second, an electronic survey was administered qualifying RFOs. Finally, survey results were integrated with semi-structured interviews with key opinion leaders in NCD research. Three major dimensions of interest were investigated - funding mechanisms, funding patterns and expectations regarding outputs. The number of RFOs in Italy is four times larger than that in Germany and the Italian research system has more project funding instruments than the German system. Regarding the funding patterns towards NCD areas, in both countries, respiratory disease research resulted as the lowest funded, whereas cancer research was the target of most funding streams. The most reported expected outputs of funded research activity were scholarly publication of articles and reports. This cross-country comparison on the Italian and German research funding structures revealed substantial differences between the two systems. The current system is prone to duplicated research efforts, popular funding for some diseases and intransparency of research results. Future research will require addressing the need for better coordination of research funding efforts, even more so if European research efforts are to play a greater role.

    Although the importance of risk communication has been pointed out over the last decade in nuclear community, both public authorities and nuclear industry have not conducted the definite actions yet. It will be reflected in the public eye that nuclear community's attitude toward communication and consultation with the public about risk issues is half-hearted, comparing with chemical and food safety fields which recently launched their risk communication activities. In this study, we conduct risk communication experiments on some risk issues associated with nuclear technology and its utilization in Tokai village, for the purpose of establishment of risk communication in our society that might be one of the new relationships between science and technology and society. The outcomes of FY2002 study are the following threefold; 1) preparation of risk communication experiments on nuclear technology and its utilization, 2) assessment of social effects of risk communication activities, 3) preparation of practical guidebook for risk communication experiments.

    Full Text Available Funded Research by project is a common frame for scientific communities and institutions today. Scientific project management set up actors in a new double bind: to contribute to a large scale dissemination of scientific process and results on one hand, and to pay attention not too much divulgate the conditions of its activity, on the other hand. These two opposite directions of practices are a specific sign of the science communication process within projects. It shows a new interpretation of science communication problems in a time of intensive competition.

  16. Biophysical Regulation of Vascular Differentiation and Assembly

    CERN Document Server

    Gerecht, Sharon

    2011-01-01

    The ability to grow stem cells in the laboratory and to guide their maturation to functional cells allows us to study the underlying mechanisms that govern vasculature differentiation and assembly in health and disease. Accumulating evidence suggests that early stages of vascular growth are exquisitely tuned by biophysical cues from the microenvironment, yet the scientific understanding of such cellular environments is still in its infancy. Comprehending these processes sufficiently to manipulate them would pave the way to controlling blood vessel growth in therapeutic applications. This book assembles the works and views of experts from various disciplines to provide a unique perspective on how different aspects of its microenvironment regulate the differentiation and assembly of the vasculature. In particular, it describes recent efforts to exploit modern engineering techniques to study and manipulate various biophysical cues. Biophysical Regulation of Vascular Differentiation and Assembly provides an inter...

    2013-06-01

    Bone adaptation to its mechanical environment, from embryonic through adult life, is thought to be the product of increased osteoblastic differentiation from mesenchymal stem cells. In parallel with tissue-scale loading, these heterogeneous populations of multipotent stem cells are subject to a variety of biophysical cues within their native microenvironments. Bone marrow-derived mesenchymal stem cells-the most broadly studied source of osteoblastic progenitors-undergo osteoblastic differentiation in vitro in response to biophysical signals, including hydrostatic pressure, fluid flow and accompanying shear stress, substrate strain and stiffness, substrate topography, and electromagnetic fields. Furthermore, stem cells may be subject to indirect regulation by mechano-sensing osteocytes positioned to more readily detect these same loading-induced signals within the bone matrix. Such paracrine and juxtacrine regulation of differentiation by osteocytes occurs in vitro. Further studies are needed to confirm both direct and indirect mechanisms of biophysical regulation within the in vivo stem cell niche.

    Naisberg, Y; Avnon, M; Weizman, A

    1995-11-01

    We present a new model of the origin of schizophrenia based on biophysical ionic shunts in neuronal (electrical) pathways. Microstructural and molecular evidence is presented for the way in which changes in the neuronal membrane ionic channels may facilitate membrane property rearrangement, leading to a change in the density and composition of the ion channel charge which in turn causes a change in ionic flow orientation and distribution. We suggest that, under abnormal conditions, ionic flow shunts are created which redirect the biophysical collateral neuronal (electrical) pathways, resulting in psychiatric signs and symptoms. This model is complementary to the biological basis of schizophrenia.

  20. Global energy modeling - A biophysical approach

    Energy Technology Data Exchange (ETDEWEB)

    Dale, Michael

    2010-09-15

    This paper contrasts the standard economic approach to energy modelling with energy models using a biophysical approach. Neither of these approaches includes changing energy-returns-on-investment (EROI) due to declining resource quality or the capital intensive nature of renewable energy sources. Both of these factors will become increasingly important in the future. An extension to the biophysical approach is outlined which encompasses a dynamic EROI function that explicitly incorporates technological learning. The model is used to explore several scenarios of long-term future energy supply especially concerning the global transition to renewable energy sources in the quest for a sustainable energy system.

    2012-01-01

    Full Text Available This article examines some of the most common methodological problems in the evaluation of academic journals in the field of communication, based on the content analysis of the ten journals with the highest impact factors in the Social Sciences Citation Index. The analysis focuses on establishing the academic and research origins and links of the authors of the articles published by these scientific publications, as well as the most predominant subject matters, genres and methodologies among the articles of these publications. This research aims to achieve two objectives: On the one hand, to analyse the role of the evaluation of communication journals in the assessment of research, which will allow us to show the difficulties of applying the bibliometric methods used by Thomson Scientific to determine the impact of journals and, on the other hand, to establish a development framework for those Spanish communication journals that meet some of the requirements of the Social Sciences Citation Index but are not yet indexed in it, either because their impact factor is still low or because of their lack of international dissemination. This research has been financed by the University of Malaga’s Research Institute for Public Relations.

  3. NASA space communications R and D (Research and Development): Issues, derived benefits, and future directions

    Science.gov (United States)

    1989-02-01

    Space communication is making immense strides since ECHO was launched in 1962. It was a simple passive reflector of signals that demonstrated the concept. Today, satellites incorporating transponders, sophisticated high-gain antennas, and stabilization systems provide voice, video, and data communications to millions of people nationally and worldwide. Applications of emerging technology, typified by NASA's Advanced Communications Technology Satellite (ACTS) to be launched in 1992, will use newer portions of the frequency spectrum (the Ka-band at 30/20 GHz), along with antennas and signal-processing that could open yet new markets and services. Government programs, directly or indirectly, are responsible for many space communications accomplishments. They are sponsored and funded in part by NASA and the U.S. Department of Defense since the early 1950s. The industry is growing rapidly and is achieving international preeminence under joint private and government sponsorship. Now, however, the U.S. space communications industry - satellite manufacturers and users, launch services providers, and communications services companies - are being forced to adapt to a different environment. International competition is growing, and terrestrial technologies such as fiber optics are claiming markets until recently dominated by satellites. At the same time, advancing technology is opening up opportunities for new applications and new markets in space exploration, for defense, and for commercial applications of several types. Space communications research, development, and applications (RD and A) programs need to adjust to these realities, be better coordinated and more efficient, and be more closely attuned to commercial markets. The programs must take advantage of RD and A results in other agencies - and in other nations.

    2013-01-01

    This report is about the risk communication cases that the author participated in after the Fukushima nuclear power plant accident. The research aims to clarify the content of information that should be provided in risk communication and to develop a risk communication tool specifically designed for this purpose. The risk communication cases were explanatory meetings intended for the residents in Fukushima Prefecture and the advisory council on radiation health effects sponsored by Tochigi Prefecture. To clarify the kinds of information necessary to provide at such meetings, we conducted a questionnaire survey of 31 food sanitation inspectors using the Delphi method. A gaming simulation was used for the development of the communication tool. We used public disclosure materials at the meetings and the survey was conducted only among those whom we obtained written informed consent. The content regarding the radioactive substances in food which was found to be the most important for the consumers to learn was ''zero risk is impossible'' (84 points), followed by ''radioactive substances and other risks (e.g. smoking and excessive alcohol intake)'' (70 points). To develop the communication tool, we used ''Quartetto (card game)'' and the contents were such as ''daily life'', ''radioactive substances'', and ''measurement''. Considering the questions raised from the residents at the meetings, an information portal such as homepages did not provide clear information on how to evaluate risks by themselves. The results from the questionnaire survey shows that it is difficult to solve this matter unless the public learns to think about the risks of various matters on their own. The lack of experts will make it necessary for the local government officials to provide more information, and therefore training on risk communication is essential. We need to evaluate the Quartetto game and revise the content considering the audience. (author)

  5. [Potential analysis of research on speech therapy-led communication training in aphasia following stroke].

    2014-01-01

    In Germany, about 100,000 people currently suffer from aphasia. This speech disorder occurs as a result of neurologic events such as stroke or traumatic brain injury. Aphasia causes major limitations in social participation and quality of life and can be associated with unemployability and social isolation. For affected persons, it is essential to regain and maintain autonomy in daily life, both at work and with family and friends. The loss of autonomy is perceived much more dramatically than the loss of speech. Clients wish to minimise this loss of autonomy in daily life. As full recovery is not achievable in chronic aphasia, treatment must focus on improved compensatory approaches and on supporting the clients' coping strategies. Based on eight randomised comparisons including 347 participants, a recent Cochrane review (Brady et al., 2012) revealed that speech therapy - as compared with no treatment - had positive effects on functional communication in clients suffering from aphasia (0.30 SMD; 95% CI[0.08 to 0.52]). There was no evidence suggesting that one type of training was superior to the others. However, quality of life and social participation were not evaluated as outcomes. Recent studies found that speech therapy-led training for communication and self-efficacy and the integration of communication partners may have a positive impact on these client-centred outcomes. Speech therapy-led training for communication within a group setting should be manualised and pilot-tested with respect to feasibility and acceptance in a German sample of people with aphasia and their communication partners. Instruments measuring quality of life and social participation can be validated within the scope of this feasibility study. These research efforts are necessary to prepare a large-scale comparative effectiveness research trial comparing the effects of both usual speech therapy and speech therapy-led group communication training on quality of life and social participation

    Effective communication is the foundation of feasibility and fidelity in practice-based pragmatic research studies. Doing a study with practices spread over several states requires long-distance communication strategies, including E-mails, faxes, telephone calls, conference calls, and texting. Compared with face-to-face communication, distance communication strategies are less familiar to most study coordinators and research teams. Developing and ensuring comfort with distance communications requires additional time and use of different talents and expertise than those required for face-to-face communication. It is necessary to make sure that messages are appropriate for the medium, clearly crafted, and presented in a manner that facilitates practices receiving and understanding the information. This discussion is based on extensive experience of 2 groups who have worked collaboratively on several large, federally funded, pragmatic trials in a practice-based research network. The goal of this article is to summarize lessons learned to facilitate the work of other research teams.

    A cornerstone of sexually transmitted infection (STI) prevention is the identification, tracing, and notification of sex partners of index patients. Although partner notification reduces disease burden and prevents new infections as well as reinfections, studies show that only a limited number of partners are ever notified. Electronic communication technologies, namely, the Internet, text messaging, and phone calls (i.e., e-notification), have the potential to expand partner services. We conducted a systematic review of studies that have investigated the acceptability and utility of e-notification. We identified 23 studies that met the following criteria: (a) 9 studies presented data on the acceptability of technology-based communications for contacting sex partner(s), and (b) 14 studies reported on the utilization of communication technologies for partner notification. Studies found high levels of interest in and acceptability of e-notification; however, there was little evidence for actual use of e-notification. Taken together, results suggest that electronic communications could have their greatest impact in notifying less committed partners who would otherwise be uninformed of their STI exposure. In addition, all studies to date have been conducted in resource-rich countries, although the low cost of e-notification may have its greatest impact in resource-constrained settings. Research is needed to determine the best practices for exploiting the opportunities afforded by electronic communications for expanding STI partner services.

  10. Communicating Academic Research Findings to IS Professionals: An Analysis of Problems

    Directory of Open Access Journals (Sweden)

    2003-01-01

    Full Text Available Because research findings often do not have direct or immediate relevance to IS professionals in industry, the question arises as to how those findings should be disseminated to them in a suitable form at such time as they do become relevant. A central argument of this paper is that the traditional mechanisms whereby academic researchers disseminate their work are prone to numerous communication breakdowns, and that much work which could potentially make valuable contributions to practice is haplessly lost within the vaults of academia. Using the well-known Shannon & Weaver communication model, three major problems are analyzed: the choice of dissemination channels, language barriers, and the alienation of academia from industry.

  11. Use of psychophysiological measurements in communication research: teachings from two studies of corporate reputation

    2013-07-01

    Full Text Available In this paper we evaluate the possibilities psychophysiological study of emotions can offer to communication research, main focus being on studies of organizational reputation. We briefly discuss the study of emotion in communication sciences and then describe the experimental protocol for studying reputation and emotions with the psychophysiological methods and offer some empirical results from our first experiments. The results obtained from studies reviewed in this paper show that reputation is at least partly emotional appeal and hence can be measured on an individual level through bodily reactions. Secondly, the results show that the valence of company-related content (e.g., news also has emotional implications and thus consequences. After presenting the studies we discuss our findings and reflect our observations during the research collaboration from two different perspectives: methodological and theoretical.

    2017-01-01

    Full Text Available In recent years, particular attention has been paid to nursing students’ therapeutic communication (TC with patients, due to a strong emphasis on patient-centered education in the Iranian healthcare reform. However, various studies have highlighted the poor communication of future nurses. Therefore, researchers have used qualitative methodology to shed light on the antecedents and consequences of nursing students’ TC and promote it. We carried out a conventional content analysis using semistructured interviews with a purposefully selected sample of 18 participants, including nursing instructors, students, and patients in hospitals affiliated to Tehran University of Medical Sciences. “Communication readiness,” “predisposing factors,” and “continuity of care” were identified as the three major themes. “Communication readiness” consisted of “physical readiness,” “academic readiness,” and “developmental readiness.” “Predisposing factors” included “contextual factors” and “educational condition.” “Continuity of care” included “patient satisfaction” and “improving nursing student’s motivation to communicate with patients.” “Communication readiness” and “predisposing factors” constitute the antecedents of nursing student’s TC with patients, and “continuity of care” is considered as its consequence. More attention needs to be paid by the regulators to TC instruction in both theoretical and clinical educational curriculum. Furthermore, all nurses must be informed about the importance of TC in promoting patient outcomes and quality of care.

    2017-12-01

    The health of Earth Science departments depends critically on effective campus outreach and communication. Where competing narratives across a broad spectrum of intellectual pursuits draws the attention of administrators for resources, geological sciences are positioned, in a unique way, to make a big impact in both public relations within the institution and outward to the community at large. Researchers, by themselves, often make poor advocates for their exciting discoveries, especially when dealing with colleagues who have little or no appreciation for the interdisciplinary nature of Earth Science. Our communication efforts at the University of North Carolina—Chapel Hill have represented the Department of Geological Sciences with spectacular visual content and riveting storytelling. Long-form features, photos, and videos published in science-oriented campus publications (Endeavors), alumni outreach (Carolina Alumni Review) and more general issues (Arts & Sciences magazine) offer glimpses into geophysical research areas such as coastal evolution, active volcanoes, and stratospheric acoustics. A well crafted story can go a long way towards raising the stature of a small department, and increase the exposure of critical environmental issues on campus. This presentation will include the key elements for crafting a compelling geoscience research story, common issues that can arise in science communication, and best practices for utilizing storytelling methods for outreach in both academic and industry settings.

  16. Aeronautical Communications Research and Development Needs for Future Air Traffic Management Applications

    Kerczewski, Robert J.

    2002-01-01

    Continuing growth in regional and global air travel has resulted in increasing traffic congestion in the air and on the ground. In spite of occasional temporary downturns due to economic recessions and catastrophic events, average growth rates of air travel have remained high since the 1960s. The resulting congestion, which constrains expansion of the air transportation industry, inflicts schedule delays and decreases overall system efficiency, creating a pressing need to develop more efficient methods of air traffic management (ATM). New ATM techniques, procedures, air space automation methods, and decision support tools are being researched and developed for deployment in time frames stretching from the next few years to the year 2020 and beyond. As these methods become more advanced and increase in complexity, the requirements for information generation, sharing and transfer among the relevant entities in the ATM system increase dramatically. However, current aeronautical communications systems will be inadequate to meet the future information transfer demands created by these advanced ATM systems. Therefore, the NASA Glenn Research Center is undertaking research programs to develop communication, methods and key technologies that can meet these future requirements. As part of this process, studies, workshops, testing and experimentation, and research and analysis have established a number of research and technology development needs. The purpose of this paper is to outline the critical research and technology needs that have been identified in these activities, and explain how these needs have been determined.

    To identify research priorities of consumers and other stakeholders to inform Cochrane Reviews in 'health communication and participation' (including such concepts as patient experience, shared decision-making and health literacy). International. We included anyone with an interest in health communication and participation. Up to 151 participants (18-80 years; 117 female) across 12 countries took part, including 48 consumers (patients, carers, consumer representatives) and 75 professionals (health professionals, policymakers, researchers) (plus 25 people who identified as both). Survey. We invited people to submit their research ideas via an online survey open for 4 weeks. Using inductive thematic analysis, we generated priority research topics, then classified these into broader themes. Participants submitted 200 research ideas, which we grouped into 21 priority topics. Key research priorities included: insufficient consumer involvement in research (19 responses), 'official' health information is contradictory and hard to understand (18 responses), communication/coordination breakdowns in health services (15 responses), health information provision a low priority for health professionals (15 responses), insufficient eliciting of patient preferences (14 responses), health services poorly understand/implement patient-centred care (14 responses), lack of holistic care impacting healthcare quality and safety (13 responses) and inadequate consumer involvement in service design (11 responses). These priorities encompassed acute and community health settings, with implications for policy and research. Priority populations of interest included people from diverse cultural and linguistic backgrounds, carers, and people with low educational attainment, or mental illness. Most frequently suggested interventions focused on training and cultural change activities for health services and health professionals. Consumers and other stakeholders want research addressing

    2011-07-01

    Full Text Available Starting from the meaning of the communication process in marketing, the authors try to identify its role in assuring the continuity of the management process in what concerns the relationships between all the partners of the company, on the long term. An emphasis is made on the role of online communication and its tools in relationship marketing. In order to validate some of the mentioned ideas the authors have chosen to undertake a qualitative marketing research among the managers of some Romanian tourism companies. The qualitative part of the study had as purpose the identification of the main tools which form the basis of the communication with the beneficiaries of the touristic services, of the way in which the companies use the online communication tools for attracting, keeping and developing the long term relationships with their customers in the virtual environment. The following tools have been analyzed: websites, email marketing campaigns, e-newsletters, online advertising, search engines, sponsored links, blogs, RSS feed, social networks, forums, online discussion groups, portals, infomediaries and instant messaging. The chosen investigation method was the selective survey, the research technique - explorative interrogation and the research instrument - semi structured detailed interview, based on a conversation guide. A very important fact is the classification resulted after the respondents were requested to mention the most efficient tools for attracting customers and for maintaining the relationships with them. Although the notoriety of the online marketing tools is high, there are some tools that are known by definition, but are not used at all or are not used correctly; or are not known by definition, but are used in practice. The authors contributed by validating a performing methodology of qualitative research, a study which will open new ways and means for making the online communication tools used for touristic services in

    Cappella, Joseph N

    2017-10-01

    Simultaneous developments in big data, social media, and computational social science have set the stage for how we think about and understand interpersonal and mass communication. This article explores some of the ways that these developments generate 4 hypothetical "vectors" - directions - into the next generation of communication research. These vectors include developments in network analysis, modeling interpersonal and social influence, recommendation systems, and the blurring of distinctions between interpersonal and mass audiences through narrowcasting and broadcasting. The methods and research in these arenas are occurring in areas outside the typical boundaries of the communication discipline but engage classic, substantive questions in mass and interpersonal communication.

  20. You talkin' to me? Interactive playback is a powerful yet underused tool in animal communication research.

    King, Stephanie L

    2015-07-01

    Over the years, playback experiments have helped further our understanding of the wonderful world of animal communication. They have provided fundamental insights into animal behaviour and the function of communicative signals in numerous taxa. As important as these experiments are, however, there is strong evidence to suggest that the information conveyed in a signal may only have value when presented interactively. By their very nature, signalling exchanges are interactive and therefore, an interactive playback design is a powerful tool for examining the function of such exchanges. While researchers working on frog and songbird vocal interactions have long championed interactive playback, it remains surprisingly underused across other taxa. The interactive playback approach is not limited to studies of acoustic signalling, but can be applied to other sensory modalities, including visual, chemical and electrical communication. Here, I discuss interactive playback as a potent yet underused technique in the field of animal behaviour. I present a concise review of studies that have used interactive playback thus far, describe how it can be applied, and discuss its limitations and challenges. My hope is that this review will result in more scientists applying this innovative technique to their own study subjects, as a means of furthering our understanding of the function of signalling interactions in animal communication systems. © 2015 The Author(s) Published by the Royal Society.

    2016-01-01

    Full Text Available If different dimensions of online interaction are neglected and/or unknowingly combined in a research study there is a risk of misleading results due to compensatory effect. With respect to the multidimensionality of online interaction, two substantially different types of online communication are defined - procreative and transmissional. The procreative online communication is understood as a person's tendency to use the internet as a space for social interaction, which essentially differs from using the internet transmissionally, as a peer-to-peer communication channel between people who are familiar with one another. The aim of this paper is to explore more deeply the procreative dimensions of online communication. Based on our conceptual framework, we defined three procreativity dimensions and developed an Online Procreativity Scale (OPS to measure them. The OPS has been validated through EFA and CFA and the three-dimensional structure has been confirmed. Using the OLS regression analyses we found that gender and psychological characteristics and social network sites (SNS use have diverse influence depending on the procreativity dimension under observation. Gender, city size, share of unfamiliar SNS friends and loneliness predicted willingness to interact with strangers, while the time spent on SNS predicted only the tendency to participate in public online interaction.

    2009-01-01

    Full Text Available The multi-disciplinary and international nature of large European projects requires powerful managerial and communicative tools to ensure the transmission of information to the end-users. One such project is TRACE entitled “Tracing Food Commodities in Europe”. One of its objectives is to provide a communication system dedicated to be the central source of information on food authenticity and traceability in Europe. This paper explores the web tools used and communication vehicles offered to scientists involved in the TRACE project to communicate internally as well as to the public. Two main tools have been built: an Intranet and a public website. The TRACE website can be accessed at http://www.trace.eu.org. A particular emphasis was placed on the efficiency, the relevance and the accessibility of the information, the publicity of the website as well as the use of the collaborative utilities. The rationale of web space design as well as integration of proprietary software solutions are presented. Perspectives on the using of web tools in the research projects are discussed.

    2011-01-01

    Despite the significant increase in the use of nanotechnology in academic research and commercial products over the past decade, there have been few studies that have explored scientists’ perceptions and attitudes about the technology. In this article, we use survey data from the leading U.S. nano-scientists to explore their perceptions about two issues: the public communication of research findings and media coverage of nanotechnology, which serves as one relatively rapid outlet for public communication. We find that leading U.S. nano-scientists do see an important connection between the public communication of research findings and public attitudes about science. Also, there is a connection between the scientists’ perceptions about media coverage and their views on the timing of public communication; scientists with positive attitudes about the media are more likely to support immediate public communication of research findings, while others believe that communication should take place only after research findings have been published through a peer-review process. We also demonstrate that journalists might have a more challenging time getting scientists to talk with them about nanotechnology news stories because nano-scientists tend to view media coverage of nanotechnology as less credible and less accurate than general science media coverage. We conclude that leading U.S. nano-scientists do feel a sense of responsibility for communicating their research findings to the public, but attitudes about the timing and the pathway of that communication vary across the group.

    Liu, Nanfeng

    It is anticipated that Arctic vegetation will respond in a variety of ways to altered temperature and precipitation patterns expected with climate change, including changes in phenology, productivity, biomass, cover and net ecosystem exchange. Remote sensing provides data and data processing methodologies for monitoring and assessing Arctic vegetation over large areas. The goal of this research was to explore the potential of hyperspectral and high spatial resolution multispectral remote sensing data for modelling two important Arctic biophysical variables: Percent Vegetation Cover (PVC) and the fraction of Absorbed Photosynthetically Active Radiation (fAPAR). A series of field experiments were conducted to collect PVC and fAPAR at three Canadian Arctic sites: (1) Sabine Peninsula, Melville Island, NU; (2) Cape Bounty Arctic Watershed Observatory (CBAWO), Melville Island, NU; and (3) Apex River Watershed (ARW), Baffin Island, NU. Linear relationships between biophysical variables and Vegetation Indices (VIs) were examined at different spatial scales using field spectra (for the Sabine Peninsula site) and high spatial resolution satellite data (for the CBAWO and ARW sites). At the Sabine Peninsula site, hyperspectral VIs exhibited a better performance for modelling PVC than multispectral VIs due to their capacity for sampling fine spectral features. The optimal hyperspectral bands were located at important spectral features observed in Arctic vegetation spectra, including leaf pigment absorption in the red wavelengths and at the red-edge, leaf water absorption in the near infrared, and leaf cellulose and lignin absorption in the shortwave infrared. At the CBAWO and ARW sites, field PVC and fAPAR exhibited strong correlations (R2 > 0.70) with the NDVI (Normalized Difference Vegetation Index) derived from high-resolution WorldView-2 data. Similarly, high spatial resolution satellite-derived fAPAR was correlated to MODIS fAPAR (R2 = 0.68), with a systematic

    Objectives We aimed to examine scholarly collaboration between oral health and prenatal providers. Oral disease is a silent epidemic with significant public health implications for pregnant women. Evidence linking poor oral health during pregnancy to adverse pregnancy and birth outcomes requires oral health and prenatal providers to communicate on the prevention, treatment and co-management matters pertaining to oral health issues among their pregnant patients. The need for inter-professional collaboration is highlighted by guidelines co-endorsed by the American College of Obstetricians and Gynecologists and the American Dental Association, stressing the importance of oral health care during pregnancy. Methods To assess if interdisciplinary communication occurs between oral health and prenatal disciplines, we conducted a network analysis of research on pregnancy-related periodontal disease. Results Social Network analysis allowed us to identify communication patterns between communities of oral health and prenatal professionals via scientific journals. Analysis of networks of citations linking journals in different fields reveals a core-periphery pattern dominated by oral health journals with some participation from medicine journals. However, an analysis of dyadic ties of citation reveals statistically significant "inbreeding" tendencies in the citation patterns: both medical and oral health journals tend to cite their own kind at greater-than-chance levels. Conclusions Despite evidence suggesting that professional collaboration benefits patients' overall health, findings from this research imply that little collaboration occurs between these two professional groups. More collaboration may be useful in addressing women's oral-systemic health concerns that result in adverse pregnancy outcomes.

    Narrative forms of communication-including entertainment education, journalism, literature, testimonials, and storytelling-are emerging as important tools for cancer prevention and control. To stimulate critical thinking about the role of narrative in cancer communication and promote a more focused and systematic program of research to understand its effects, we propose a typology of narrative application in cancer control. We assert that narrative has four distinctive capabilities: overcoming resistance, facilitating information processing, providing surrogate social connections, and addressing emotional and existential issues. We further assert that different capabilities are applicable to different outcomes across the cancer control continuum (e.g., prevention, detection, diagnosis, treatment, survivorship). This article describes the empirical evidence and theoretical rationale supporting propositions in the typology, identifies variables likely to moderate narrative effects, raises ethical issues to be addressed when using narrative communication in cancer prevention and control efforts, and discusses potential limitations of using narrative in this way. Future research needs based on these propositions are outlined and encouraged.

    Full Text Available In the process of ocean development, the technology for maritime communication system is a hot research field, of which information security is vital for the normal operation of the whole system, and that is also one of the difficulties in the research of maritime communication system. In this paper, a kind of maritime communication cryptographic SOC(system on chip is introduced, and its compiler framework is put forward through analysis of working mode and problems faced by compiler front end. Then, a loop unrolling factor calculating algorithm based on queue theory, named UFBOQ (unrolling factor based on queue, is proposed to make parallel optimization in the compiler frontend with consideration of the instruction memory capacity limit. Finally, the scalar replacement method is used to optimize unrolled code to solve the memory access latency on the parallel computing efficiency, for continuous data storage characteristics of cryptographic algorithm. The UFBOQ algorithm and scalar replacement prove effective and appropriate, of which the effect achieves the linear speedup.

    Sustainable river management relies on diverse and multi-faceted knowledge from fundamental and applied research. Communicating the context, added value and potential use of river research to actors working in multiple disciplines or organizations is challenging. RiverCare is a research programme studying the mid-term effects of innovative river interventions in the Netherlands. Effective communication between researchers and potential users of scientific information, such as water professionals, requires an interactive, two-way communication approach. As part of the communication strategy, we are designing a knowledge platform to provide access to, explain and gather feedback about the potential use of results from water professionals. The knowledge platform is a combination of online services including: a content management system in which storylines are the main component; a data repository to the underlying research data and; hyperlinks to existing online sites that present our results via short news articles. Storylines engage water professionals via experiences or stories of river management actors to explain research outputs instead of or in addition to more technical means such as scientific papers and reports. The use of storylines enables us to explain research outcomes in a way that is captivating and easily understood by a multi-disciplinary audience. To explore its usefulness as communication approach, we developed a storyline example for research about stakeholder perceptions of a re-landscaping intervention in the Waal river in the Netherlands. The storyline's layout consisted of a menu outline and three tabs: (1) storyline's content; (2) contact details; and (3) links to available resources or related publications. The storyline's content was divided in four sections including subsections to navigate. Each section had a heading statement or question to engage users: "Imagine this!"; "What matters? Places matter to people"; "Surveying people

  10. Risky, aggressive, or emotional driving: addressing the need for consistent communication in research.

    Dula, Chris S; Geller, E Scott

    2003-01-01

    Researchers agree that a consistent definition for aggressive driving is lacking. Such definitional ambiguity in the literature impedes the accumulation of accurate and precise information, and prevents researchers from communicating clearly about findings and implications for future research directions. This dramatically slows progress in understanding the causes and maintenance factors of aggressive driving. This article critiques prevailing definitions of driver aggression and generates a definition that, if used consistently, can improve the utility of future research. Pertinent driving behaviors have been variably labeled in the literature as risky, aggressive, or road rage. The authors suggest that the term "road rage" be eliminated from research because it has been used inconsistently and has little probability of being clarified and applied consistently. Instead, driving behaviors that endanger or have the potential to endanger others should be considered as lying on a behavioral spectrum of dangerous driving. Three dimensions of dangerous driving are delineated: (a). intentional acts of aggression toward others, (b). negative emotions experienced while driving, and (c). risk-taking. The adoption of a standardized definition for aggressive driving should spark researchers to use more explicit operational definitions that are consistent with theoretical foundations. The use of consistent and unambiguous operational definitions will increase the precision of measurement in research and enhance authors' ability to communicate clearly about findings and conclusions. As this occurs over time, industry will reap benefits from more carefully conducted research. Such benefits may include the development of more valid and reliable means of selecting safe professional drivers, conducting accurate risk assessments, and creating preventative and remedial dangerous driving safety programs.

  11. Researchers' perspectives on open access scholarly communication in Tanzanian public universities

    2009-04-01

    Full Text Available This research explored the awareness, usage and perspectives of Tanzanian researchers on open access as a mode of scholarly communication. A survey questionnaire targeted 544 respondents selected through stratified random sampling from a population of 1088 university researchers of the six public universities in Tanzania. With a response rate of 73%, the data were analysed using the Statistical Package for Social Sciences. The study reveals that the majority of the researchers were aware of and were positive towards open access. Findings further indicate that the majority of researchers in Tanzanian public universities used open access outlets more to access scholarly content than to disseminate their own research findings. It seems that most of these researchers would support open access publishing more if issues of recognition, quality and ownership were resolved. Thus many of them supported the idea of establishing institutional repositories at their respective universities as a way of improving the dissemination of local content. The study recommends that public universities and other research institutions in the country should consider establishing institutional repositories, with appropriate quality assurance measures, to improve the dissemination of research output emanating from these institutions.

    2009-01-01

    The last decade has seen the development of a number of novel biophysical methods that allow the manipulation and study of individual biomolecules. The ability to monitor biological processes at this fundamental level of sensitivity has given rise to an improved understanding of the underlying molecular mechanisms. Through the removal of ensemble averaging, distributions and fluctuations of molecular properties can be characterized, transient intermediates identified, and catalytic mechanisms elucidated. By applying forces on biomolecules while monitoring their activity, important information can be obtained on how proteins couple function to structure. The Handbook of Single-Molecule Biophysics provides an introduction to these techniques and presents an extensive discussion of the new biological insights obtained from them. Coverage includes: Experimental techniques to monitor and manipulate individual biomolecules The use of single-molecule techniques in super-resolution and functional imaging Single-molec...

    2002-06-01

    Some biophysical characteristics of the skin collagen from Scomberoides commersonianus were measured and compared to those of rat tail tendon. Stress-strain data indicate that the strain at break as well as the tensile strength of the fish skin without scales increased significantly. The maximum tension in case of rat skin is at least a factor of two higher than that observed in fish skin. The much lower hydrothermal isometric tension measurements observed in fish skin are attributable to a lesser number of heat stable crosslinks. Stress relaxation measurements in the fish skin indicate that more than one relaxation process may be involved in the stabilization of collagenous matrix. The observed differences in the biophysical behavior of fish skin may well arise from combination of changes in extent of hydroxylation of proline in collagen synthesis, hydrogen bond network and fibril orientation as compared to rat tail tendon.

  15. Biophysical Aspects of Transmembrane Signaling

    CERN Document Server

    Damjanovich, Sandor

    2005-01-01

    Transmembrane signaling is one of the most significant cell biological events in the life and death of cells in general and lymphocytes in particular. Until recently biochemists and biophysicists were not accustomed to thinking of these processes from the side of a high number of complex biochemical events and an equally high number of physical changes at molecular and cellular levels at the same time. Both types of researchers were convinced that their findings are the most decisive, having higher importance than the findings of the other scientist population. Both casts were wrong. Life, even at cellular level, has a number of interacting physical and biochemical mechanisms, which finally build up the creation of an "excited" cell that will respond to particular signals from the outer or inner world. This book handles both aspects of the signalling events, and in some cases tries to unify our concepts and help understand the signals that govern the life and death of our cells. Not only the understanding, bu...

    This study focuses the attention on an indoor fast neutron generator for biophysical and electronic applications. More specifically, the findings obtained by several simulations with the MCNP Monte Carlo code, necessary for the realization of a shield for indoor measurements, are presented. Furthermore, an evaluation of the neutron spectrum modification caused by the shielding is reported. Fast neutron generators are a valid and interesting available source of neutrons, increasingly employed in a wide range of research fields, such as science and engineering. The employed portable pulsed neutron source is a MP320 Thermo Scientific neutron generator, able to generate 2.5 MeV neutrons with a neutron yield of 2.0 x 106 n/s, a pulse rate of 250 Hz to 20 KHz and a duty factor varying from 5% to 100%. The neutron generator, based on Deuterium-Deuterium nuclear fusion reactions, is employed in conjunction with a solid-state photon detector, made of n-type high-purity germanium (PINS-GMX by ORTEC) and it is mainly addressed to biophysical and electronic studies. The present study showed a proposal for the realization of a shield necessary for indoor applications for MP320 neutron generator, with a particular analysis of the transport of neutrons simulated with Monte Carlo code and described the two main lines of research in which the source will be used.

  17. Creative Climate: A global ten-year communications, research and learning project about environmental change

    Science.gov (United States)

    Brandon, M. A.; Smith, J.

    2010-12-01

    The next ten years have been described by influential science and policy figures as ‘the most important in human history’. Many believe that the actions taken will decide whether we catastrophically change the atmosphere and eradicate our fellow species or find an alternative, less-damaging development path. But communications and public engagement initiatives have tended to focus on near term impacts or debates - whether they emphasise hazards, or trumpet ‘solutions’. There are signs of diminishing returns on communications and public engagement efforts, and serious obstacles to engaging around 40% of publics in e.g. the US and the UK. The Creative Climate web project takes a new approach, inviting people to see humanity’s intellectual and practical journey with these issues as an inspiring, dynamic and unfolding story. We are inviting people to join us in building a huge living archive of experiences and ideas that respond to these issues. The website will collect thoughts and stories from doorstep to workplace, from lab to garden; from international conference to community meeting - from all over the world. The body of diaries lie at the core of the project, but these are supplemented by the offer of free online learning resources and broadcast-quality audio and video materials. The project is experimental in terms of its scope, its approach to environmental communications and debate and in its use of media. It works with formal partners, including the BBC, yet also makes the most of the opportunities for user generated content to create a rich multimedia resource that can support research, learning and engagement. The design of the project is informed by environmental social science and communications research, and by an awareness of the unfolding potential of Internet based communications to support social change. It is also intended that the Creative Climate platform will develop so as to serve researchers by offering an open resource of qualitative

    2011-12-01

    Full Text Available Abstract Background Effective provider-parent communication can improve childhood vaccination uptake and strengthen immunisation services in low- and middle-income countries (LMICs. Building capacity to improve communication strategies has been neglected. Rigorous research exists but is not readily found or applicable to LMICs, making it difficult for policy makers to use it to inform vaccination policies and practice. The aim of this project is to build research knowledge and capacity to use evidence-based strategies for improving communication about childhood vaccinations with parents and communities in LMICs. Methods and design This project is a mixed methods study with six sub-studies. In sub-study one, we will develop a systematic map of provider-parent communication interventions for childhood vaccinations by screening and extracting data from relevant literature. This map will inform sub-study two, in which we will develop a taxonomy of interventions to improve provider-parent communication around childhood vaccination. In sub-study three, the taxonomy will be populated with trial citations to create an evidence map, which will also identify how evidence is linked to communication barriers regarding vaccination. In the project's fourth sub-study, we will present the interventions map, taxonomy, and evidence map to international stakeholders to identify high-priority topics for systematic reviews of interventions to improve parent-provider communication for childhood vaccination. We will produce systematic reviews of the effects of high-priority interventions in the fifth sub-study. In the sixth and final sub-study of the project, evidence from the systematic reviews will be translated into accessible formats and messages for dissemination to LMICs. Discussion This project combines evidence mapping, conceptual and taxonomy development, priority setting, systematic reviews, and knowledge transfer. It will build and share concepts, terms

    Skolnick, Malcolm

    2009-03-01

    The interface between physics and biology is one of the fastest growing subfields of physics. As knowledge of such topics as cellular processes and complex ecological systems advances, researchers have found that progress in understanding these and other systems requires application of more quantitative approaches. Today, there is a growing demand for quantitative and computational skills in biological research and the commercialization of that research. The fragmented teaching of science in our universities still leaves biology outside the quantitative and mathematical culture that is the foundation of physics. This is particularly inopportune at a time when the needs for quantitative thinking about biological systems are exploding. More physicists should be encouraged to become active in research and development in the growing application fields of biophysics including molecular genetics, biomedical imaging, tissue generation and regeneration, drug development, prosthetics, neural and brain function, kinetics of nonequilibrium open biological systems, metabolic networks, biological transport processes, large-scale biochemical networks and stochastic processes in biochemical systems to name a few. In addition to moving into basic research in these areas, there is increasing opportunity for physicists in industry beginning with entrepreneurial roles in taking research results out of the laboratory and in the industries who perfect and market the inventions and developments that physicists produce. In this talk we will identify and discuss emerging opportunities for physicists in biophysical and biotechnological pursuits ranging from basic research through development of applications and commercialization of results. This will include discussion of the roles of physicists in non-traditional areas apart from academia such as patent law, financial analysis and regulatory science and the problem sets assigned in education and training that will enable future

  4. Digital information and communication networks and scientific research substance: An investigation of meteorology

    Science.gov (United States)

    Shen, Yi

    This study investigated research meteorologists' current usage and evaluation of information and communication technologies (ICT) in performing research tasks and the current relationship between meteorologists' ICT use and content characteristics of their research outputs. It surveyed research meteorologists working in three NOAA funded research institutes based at universities. Follow-up interviews with two selective samples of the survey participants were conducted to provide additional evidence to survey results and make suggestions for future measurement development work. Multiple regression analysis was performed to test the hypothesized relationships between meteorologists' ICT use and two substantive characteristics of their research---data integration and intra-/interdisciplinarity. Descriptive statistics were calculated to discern inferences of the scientists' current state of use and their degree of satisfaction with ICT tools. Follow-up interviews were transcribed and analyzed qualitatively with open coding and axial coding. The study findings contradicted the two assumptions of ICT effects on meteorological research by showing that the greater frequency of networked ICT use is not significantly associated with either greater data integration in research analysis, or greater intra- or interdisciplinary research. The major ICT barrier is the lack of a data and information infrastructure and support system for integrated, standardized, specialized, and easily accessible data and information from distributed servers. Suggestions were provided on the improvements of technical, social, political, and educational settings to promote large-scale date integration and intra-/interdisciplinary research. By moving further from theoretical assumptions to practical examinations, the research findings provide empirical evidence of Bowker's theories on the social shaping and social impact of infrastructure in sciences and affirmed some of Bowker's arguments regarding

    Science.gov (United States)

    Murphy, Daniel J.; Pinelli, Thomas E.

    1994-01-01

    This paper discusses the use of computers as a medium for communication (CMC) used by aerospace engineers and scientists to obtain and/or provide technical information related to research and development activities. The data were obtained from a questionnaire survey that yielded 1006 mail responses. In addition to communication media, the research also investigates degrees of task uncertainty, environmental complexity, and other relevant variables that can affect aerospace workers' information-seeking strategies. While findings indicate that many individuals report CMC is an important function in their communication patterns, the research indicates that CMC is used less often and deemed less valuable than other more conventional media, such as paper documents, group meetings, telephone and face-to-face conversations. Fewer than one third of the individuals in the survey account for nearly eighty percent of the reported CMC use, and another twenty percent indicate they do not use the medium at all, its availability notwithstanding. These preliminary findings suggest that CMC is not as pervasive a communication medium among aerospace workers as the researcher expect a priori. The reasons underlying the reported media use are not yet fully known, and this suggests that continuing research in this area may be valuable.

    2018-01-01

    The need for science education and outreach is great. However, despite the ever-growing body of available scientific information, facts are often misrepresented to or misunderstood by the general public. This can result in uninformed decisions that negatively impact society at both individual and community levels. One solution to this problem is to make scientific information more available to the public through outreach programs. Most outreach programs, however, focus on health initiatives, STEM programs, or young audiences exclusively. This article describes a collaboration between the Research and Learning Center at the Fort Worth Museum of Science and History and an interdisciplinary team of researchers from the Dallas–Fort Worth (DFW) metroplex area. The collaboration was a pilot effort of a science communication fellowship and was designed to train researchers to effectively convey current science information to the public with a focus on lifelong learning. We focus on the broader idea of a university-museum collaboration that bridges the science communication gap as we outline the process of forming this collaboration, lessons we learned from the process, and directions that can support future collaborations.

    2018-06-04

    Increasing numbers of physicists engage in research activities that address biological questions from physics perspectives or strive to develop physics insights from active biological processes. The on-going development and success of such activities morph our ways of thinking about what it is to 'do biophysics' and add to our understanding of the physics of life. Many scientists in this research and teaching landscape are homed in physics departments. A challenge for a hosting department is how to group, name and structure such biophysicists to best add value to their emerging research and teaching but also to the portfolio of the whole department. Here we discuss these issues and speculate on strategies. Creative Commons Attribution license.

  8. On Effective Graphic Communication of Health Inequality: Considerations for Health Policy Researchers.

    Policy Points: Effective graphs can be a powerful tool in communicating health inequality. The choice of graphs is often based on preferences and familiarity rather than science. According to the literature on graph perception, effective graphs allow human brains to decode visual cues easily. Dot charts are easier to decode than bar charts, and thus they are more effective. Dot charts are a flexible and versatile way to display information about health inequality. Consistent with the health risk communication literature, the captions accompanying health inequality graphs should provide a numerical, explicitly calculated description of health inequality, expressed in absolute and relative terms, from carefully thought-out perspectives. Graphs are an essential tool for communicating health inequality, a key health policy concern. The choice of graphs is often driven by personal preferences and familiarity. Our article is aimed at health policy researchers developing health inequality graphs for policy and scientific audiences and seeks to (1) raise awareness of the effective use of graphs in communicating health inequality; (2) advocate for a particular type of graph (ie, dot charts) to depict health inequality; and (3) suggest key considerations for the captions accompanying health inequality graphs. Using composite review methods, we selected the prevailing recommendations for improving graphs in scientific reporting. To find the origins of these recommendations, we reviewed the literature on graph perception and then applied what we learned to the context of health inequality. In addition, drawing from the numeracy literature in health risk communication, we examined numeric and verbal formats to explain health inequality graphs. Many disciplines offer commonsense recommendations for visually presenting quantitative data. The literature on graph perception, which defines effective graphs as those allowing the easy decoding of visual cues in human brains, shows

    2014-03-01

    First-hand, open-ended experimentation is key for effective formal and informal biophysics education. We developed, tested and assessed multiple new platforms that enable students and children to directly interact with and learn about microscopic biophysical processes: (1) Biotic games that enable local and online play using galvano- and photo-tactic stimulation of micro-swimmers, illustrating concepts such as biased random walks, Low Reynolds number hydrodynamics, and Brownian motion; (2) an undergraduate course where students learn optics, electronics, micro-fluidics, real time image analysis, and instrument control by building biotic games; and (3) a graduate class on the biophysics of multi-cellular systems that contains a cloud experimentation lab enabling students to execute open-ended chemotaxis experiments on slimemolds online, analyze their data, and build biophysical models. Our work aims to generate the equivalent excitement and educational impact for biophysics as robotics and video games have had for mechatronics and computer science, respectively. We also discuss how scaled-up cloud experimentation systems can support MOOCs with true lab components and life-science research in general.

  13. A Multi-User Model for Effectively Communicating Research Through Electronic Media

    Science.gov (United States)

    Hinds, J. J.; Fairley, J. P.

    2003-12-01

    Electronic media have demonstrated potential for data exchange, dissemination of results to other scientists, communication with community interest groups, and education of the general public regarding scientific advances. Few researchers, however, receive training in the skills required to capture the attention of the broad spectrum of Internet users. Because different people assimilate information in different ways, effective communication is best accomplished using an appropriate mix of photographs, graphics, tables, and text. In addition, effective web page design requires a clear, consistent organizational structure, easily-navigated layout, and attention to details such as page printability, downloading time, and minimal page scrolling. One of the strengths of electronic media is that the user can chose an appropriate level of involvement for his or her interest. In designing a web page for the multidisciplinary NSF/EPSCoR "Biocomplexity in Extreme Environments" project, we divided potential users into three categories based on our perception of the level of detail they required: 1) project participants, 2) non-participants with technical backgrounds, and 3) the general public. By understanding the needs and expectations of potential viewers, it was possible to present each group with an appropriate balance of visual and textural elements. For example, project participants are often most interested in raw data, which can be effectively presented in tabular format. Non-participants with technical backgrounds are more interested in analyzed data, while a project overview, presented through photographs and graphics with minimal text, will be most effective for communicating with the general public. The completed web page illustrates one solution for effectively communicating with a diverse audience, and provides examples for meeting many of the challenges of web page design.

    The ability to communicate effectively as a healthcare professional has come into greater focus as the role of pharmacists expands from "medicine-based" to "client-based" (e.g., working with patients, their families, and in multidisciplinary interactions). The ability to communicate cannot be acquired solely in the classroom; a large part of acquiring such skill is based on practical experience. Role-playing with simulated patients has already been implemented in pharmaceutical education; in that sense, opportunities to receive education in practical communication are increasing. However, in order to assure that these educational opportunities are more than "experiences" in theory alone, aspects of communications training that are satisfactory or need improvement must be clarified through empirical studies. While data used in pharmaceutical studies have mainly been quantitative in nature, data required for medical communication studies is generally more qualitative. Only recently the importance of qualitative research has been recognized in pharmaceutical studies, a field in which any aspect difficult to express numerically has been considered subjective, and thus less acceptable. Against this backdrop, this report introduces an aspect of communication research that employs the Roter method of interaction process analysis (RIAS), a medical communication analyzing method by Professor Debra Roter at Johns Hopkins University. RIAS is a quantitative analysis of qualitative data. I want to discuss the significance of using results of research based on qualitative data to improve the quality of communication.

    The research about the fate and behavior of engineered nanoparticles in the environment is despite its wide applications still in the early stages. 'There is a high level of scientific uncertainty in nanoparticle research' is often stated in the scientific community. Knowledge about these uncertainties might be of interest to other scientists, experts and laymen. But how could these uncertainties be characterized and are they communicated within the scientific literature and the mass media? To answer these questions, the current state of scientific knowledge about scientific uncertainty through the example of environmental nanoparticle research was characterized and the communication of these uncertainties within the scientific literature is compared with its media coverage in the field of nanotechnologies. The scientific uncertainty within the field of environmental fate of nanoparticles is by method uncertainties and a general lack of data concerning the fate and effects of nanoparticles and their mechanisms in the environment, and by the uncertain transferability of results to the environmental system. In the scientific literature, scientific uncertainties, their sources, and consequences are mentioned with different foci and to a different extent. As expected, the authors in research papers focus on the certainty of specific results within their specific research question, whereas in review papers, the uncertainties due to a general lack of data are emphasized and the sources and consequences are discussed in a broader environmental context. In the mass media, nanotechnology is often framed as rather certain and positive aspects and benefits are emphasized. Although reporting about a new technology, only in one-third of the reports scientific uncertainties are mentioned. Scientific uncertainties are most often mentioned together with risk and they arise primarily from unknown harmful effects to human health. Environmental issues itself are seldom mentioned

    Inhalation of nanoparticles (NP), including lightweight airborne carbonaceous nanomaterials (CNM), poses a direct and systemic health threat to those who handle them. Inhaled NP penetrate deep pulmonary structures in which they first interact with the pulmonary surfactant (PS) lining at the alveolar air-water interface. In spite of many research efforts, there is a gap of knowledge between in vitro biophysical study and in vivo inhalation toxicology since all existing biophysical models handle NP-PS interactions in the liquid phase. This technical limitation, inherent in current in vitro methodologies, makes it impossible to simulate how airborne NP deposit at the PS film and interact with it. Existing in vitro NP-PS studies using liquid-suspended particles have been shown to artificially inflate the no-observed adverse effect level of NP exposure when compared to in vivo inhalation studies and international occupational exposure limits (OELs). Here, we developed an in vitro methodology called the constrained drop surfactometer (CDS) to quantitatively study PS inhibition by airborne CNM. We show that airborne multiwalled carbon nanotubes and graphene nanoplatelets induce a concentration-dependent PS inhibition under physiologically relevant conditions. The CNM aerosol concentrations controlled in the CDS are comparable to those defined in international OELs. Development of the CDS has the potential to advance our understanding of how submicron airborne nanomaterials affect the PS lining of the lung.

    Agricultural production is sensitive to weather and thus directly affected by climate change. Plausible estimates of these climate change impacts require combined use of climate, crop, and economic models. Results from previous studies vary substantially due to differences in models, scenarios, and data. This paper is part of a collective effort to systematically integrate these three types of models. We focus on the economic component of the assessment, investigating how nine global economic models of agriculture represent endogenous responses to seven standardized climate change scenarios produced by two climate and five crop models. These responses include adjustments in yields, area, consumption, and international trade. We apply biophysical shocks derived from the Intergovernmental Panel on Climate Change's representative concentration pathway with end-of-century radiative forcing of 8.5 W/m(sup 2). The mean biophysical yield effect with no incremental CO2 fertilization is a 17% reduction globally by 2050 relative to a scenario with unchanging climate. Endogenous economic responses reduce yield loss to 11%, increase area of major crops by 11%, and reduce consumption by 3%. Agricultural production, cropland area, trade, and prices show the greatest degree of variability in response to climate change, and consumption the lowest. The sources of these differences include model structure and specification; in particular, model assumptions about ease of land use conversion, intensification, and trade. This study identifies where models disagree on the relative responses to climate shocks and highlights research activities needed to improve the representation of agricultural adaptation responses to climate change.

  20. Developments in Acoustic Navigation and Communication for High-Latitude Ocean Research

    2006-12-01

    Developments in autonomous platforms (profiling floats, drifters, long-range gliders and propeller-driven vehicles) offer the possibility of unprecedented access to logistically difficult polar regions that challenge conventional techniques. Currently, however, navigation and telemetry for these platforms rely on satellite positioning and communications poorly suited for high-latitude applications where ice cover restricts access to the sea surface. A similar infrastructure offering basin-wide acoustic geolocation and telemetry would allow the community to employ autonomous platforms to address previously intractable problems in Arctic oceanography. Two recent efforts toward the development of such an infrastructure are reported here. As part of an observational array monitoring fluxes through Davis Strait, development of real-time RAFOS acoustic navigation for gliders has been ongoing since autumn 2004. To date, test deployments have been conducted in a 260 Hz field in the Pacific and 780 Hz fields off Norway and in Davis Strait. Real-time navigation accuracy of ~1~km is achievable. Autonomously navigating gliders will operate under ice cover beginning in autumn 2006. In addition to glider navigation development, the Davis Strait array moorings carry fixed RAFOS recorders to study propagation over a range of distances under seasonally varying ice cover. Results from the under-ice propagation and glider navigation experiments are presented. Motivated by the need to coordinate these types of development efforts, an international group of acousticians, autonomous platform developers, high-latitude oceanographers and marine mammal researchers gathered in Seattle, U.S.A. from 27 February -- 1 March 2006 for an NSF Office of Polar Programs sponsored Acoustic Navigation and Communication for High-latitude Ocean Research (ANCHOR) workshop. Workshop participants focused on summarizing the current state of knowledge concerning Arctic acoustics, navigation and communications

    2014-01-01

    Announcements by public figures and celebrities about cancer diagnosis or death represent significant events in public life. But what are the substantive effects of such events, if any? The purpose of this article is to systematically review studies that examined the impact of public figure cancer announcements on cancer-oriented outcomes. Using comprehensive search procedures, we identified k = 19 studies that examined 11 distinct public figures. The most commonly studied public figures were Jade Goody, Kylie Minogue, Nancy Reagan, and Steve Jobs, with the most common cancers studied being breast (53%), cervical (21%), and pancreatic (21%) cancer. Most studies assessed multiple outcome variables, including behavioral outcomes (k = 15), media coverage (k = 10), information seeking (k = 8), cancer incidence (k = 3), and interpersonal communication (k = 2). Results fairly consistently indicated that cancer announcements from public figures had meaningful effects on many, if not most, of these outcome variables. While such events essentially act as naturally occurring interventions, the effects tend to be relatively short term. Gaps in this literature include few contemporary studies of high-profile public figures in the United States and a general lack of theory-based research. Directions for future research as well as implications for cancer communication and prevention are discussed.

  2. An Evolving Triadic World: A Theoretical Framework for Global Communication Research

    2015-08-01

    Full Text Available A macro theory that recognizes the world’s three competing center-clusters and their respective hinterlands o?ers a realistic framework for global communication research. This study has used recent data on world trade, computers, Internet hosts, and high-tech exports to map the triadization of the world in the Information Age. The original dependency theory and world-system theory perspectives emphasized the hierarchical linking of national societies to the capitalist world-economy in a center-periphery structure. The proposed global-triadization formulation looks at the center-periphery structure in terms of a capitalist world-economy dominated by three competing center economic clusters, each of which has a dependent hinterland comprising peripheral economic clusters. These clusters may not necessarily be geographically contiguous. Strong-weak relationships may exist within each center-cluster, as well as within each periphery-cluster, with one center-cluster occupying a hegemonic role. The rudimentary Information-Society Power Index, constructed for this study, can guide the researcher to test an abundance of hypotheses on the pattern of global communication and information ?ow with particular attention to source, message, channel, and receiver.

    Full Text Available The “E.R. Caianiello” Central Library of the University of Salerno preserves many private bibliographic collections. This paper focuses on their valorization through an integrated approach encompassing dissemination, social media communication and research. The dissemination was developed as part of the collaboration to the Wikimedia projects. In particular we created a GLAM working group that enriched Wikipedia, Wikidata and Commons with contents and data related to the private collections. As for the communication, after drafting an editorial plan and a social media policy, the social media profiles of the library were used to provide information to the general public about the collections, including the bibliographic description and a link to the biographic article on Wikipedia, using a dedicated hashtag #fondispeciali. The research path included the organization of the conference “Biblioteca di biblioteche”, held on May 26, 2016 and supported by AIB Campania and Wikimedia Italia, which inaugurated a bio-bibliographic exhibition dedicated to the Cilento, Cuomo, Grottanelli and Paparelli collections. The valorization process generated a positive impact in many areas including the production of new referenced contents, the creation of collaborative networks with other cultural institutions and the continuous training of librarians involved in the projects.

    2013-01-01

    The purpose of this article is to develop an evidence-based resource for knowing and communicating the complexities involved for both males and females in implementing and sustaining a physically active lifestyle shortly after spinal cord injury (SCI). Synthesizing a set of qualitative and quantitative studies with over 500 spinal cord injured people, the article represents research utilizing the genre of ethnographic creative non-fiction. This genre of representation holds enormous potential for researchers in terms of disseminating their findings to diverse audiences beyond the academy, and having real impact. The ethnographic creative non-fictions show together for the first time the barriers, determinants, benefits, trajectories, emotions, fears, preferred methods and messengers for delivering important physical activity information to men and women with a SCI. The article contributes to knowledge by showing the embodied complexities involved when in rehabilitation for both males and females in implementing and sustaining a physically active lifestyle shortly after SCI. It also makes a contribution to practice by providing researchers, health care professionals and disability user-groups with a theory and evidence based resource to assist in informing, teaching and enabling people living with SCI to initiate and maintain a physically active lifestyle. Stories may be a highly effective tool to communicate with and to influence spinal cord injured people's activity. The findings of this research showed the many benefits and barriers to developing and sustaining a physically active lifestyle shortly after spinal cord injury. The preferred methods and messengers for delivering physical activity information as well as the activity types, intensities and durations of physical activity for men and women were also shown. Within rehabilitation, spinal cord injured people need to be offered accessible knowledge about how to implement and sustain a physically active

    Full Text Available Since the majority of top-level researchers are men, how does this vertical gender-segregation affect students’ perceptions of a research career? In the current study, an experimental manipulation either reminded students of academia’s current dominance of men or of its improving gender-balance. The results showed that women primed with the dominance of men anticipated much higher social identity threats (e.g., fear of discrimination in a future research career as compared to a control group. In contrast, women primed with the improving gender-balance anticipated much lower threat. Further, the dominance of men prime increased men’s interest in the PhD program, as compared to controls. Women’s interest was unaffected by the prime, but their lower interest as compared to men’s across conditions was mediated by their lower research self-efficacy (i.e., competence beliefs. The results imply that communicating gender-equality progress may allow women to consider a career in research without the barrier of social identity threat.

    Full Text Available Publishers, vendors and librarians often discuss the needs of the researcher. However, it is not often that information professionals have the opportunity to sit down with a group of researchers, listen to their perspective and ask them questions. The UKSG One-Day Conference held in London in November 2016 offered such an opportunity with a panel session of researchers chaired by Charlie Rapple of Kudos. The researchers shared with us their frustrations about scholarly communications ecosystems and their ideas for improvements. A major source of frustration is the need for academics to publish, and publish well, to keep their jobs and progress. In doing so, they face what seem to be often insurmountable obstacles that they feel powerless to address or change. Themes of the session were the lack of incentives to peer review and join editorial boards, the role of social networking sites, open access and collaboration with libraries. The researchers who so generously gave us their time are Professor Andy Miah (University of Salford, Dr Mícheál Ó Fathartaigh (Dublin Business School and Dr Sabina Michnowicz (Hazard Centre, University College London.

    2011-12-01

    Full Text Available Thesis is the research outcome that a graduate student spends most of his or her time and energies to achieve. Therefore, the research process of student’s thesis writing is an important topic to be investigated. The main purpose of this study is to explore graduate students’ information seeking behavior during the process of thesis writing. Ten graduate students in the field of communication were interviewed, and their information horizon maps as well as bibliographical references were analyzed also. Results showed that the library, as a formal channel, is the primary source for graduate students. The documents that they used most often were theses and dissertations, monographs, and journals. In addition to the formal channels, social network also played as a very important role in students’ research process. The networks even changed their information seeking behaviors in formal channels. Students reported several problems encountered in the research process, such as lacking of the background knowledge of the interdisciplinary, being unable to find out the core and relevant documents from the search results, etc. In conclusion, graduate students’ information seeking behavior changed at different stages in the research process.

  10. Social and Biophysical Predictors of Public Perceptions of Extreme Fires

    2013-12-01

    To date, what constitutes an 'extreme' fire has been approached separately by biophysical and social scientists. Research on the biophysical characteristics of fires has identified potential dimensions of extremity, including fire size and vegetation mortality. On the social side, factors such as the degree of immediate impact to one's life and property or the extent of social disruption in the community contribute to a perception of extremity. However, some biophysical characteristics may also contribute to perceptions of extremity, including number of simultaneous ignitions, rapidity of fire spread, atypical fire behavior, and intensity of smoke. Perceptions of these impacts can vary within and across communities, but no studies to date have investigated such perceptions in a comprehensive way. In this study, we address the question, to what extent is the magnitude of impact of fires on WUI residents' well-being explained by measurable biophysical characteristics of the fire and subjective evaluations of the personal and community-level impacts of the fire? We bring together diverse strands of psychological theory, including landscape perception, mental models, risk perception, and community studies. The majority of social science research on fires has been in the form of qualitative case studies, and our study is methodologically unique by using a nested design (hierarchical modeling) to enable generalizable conclusions across a wide range of fires and human communities. We identified fires that burned in 2011 or 2012 in the northern Rocky Mountain region that were at least 1,000 acres and that intersected (within 15 km) urban clusters or identified Census places. For fires where an adequately large number of households was located in proximity to the fire, we drew random samples of approximately 150 individuals for each fire. We used a hybrid internet (Qualtrics) and mail survey, following the Dillman method, to measure individual perceptions. We developed two

    Developing communication to support health and well-being of vulnerable communities requires a multifaceted understanding of local perspectives of contextual challenges and potentials for change. While participatory research enhances understanding, robust methodologies are necessary to translate emerging concepts into viable communication approaches. Communicators and change agents need to clarify pathways for change, barriers and enablers for change, as well as the role, orientation, and content of communication to support change. While various approaches to participatory action research with vulnerable communities have been developed, there is a dearth of methodologies that address the formulation of communication concepts that can be applied at scale. The Action Media methodology has been refined over a period of two decades, being applied to addressing HIV, related aspects such as gender-based violence, as well as broader issues, such as maternal and child health, sanitation, and malaria in Africa, The Caribbean, and Asia. The approach employs a sequence of interactive sessions involving communicator researchers and participants from one or more communities that face social or health challenges. Sessions focus on understanding audiences through their engagement with these challenges and leading to shaping of relevant communication concepts that can be linked to mobilization for change. The Action Media methodology contributes to processes of shared learning linked to addressing social and health challenges. This includes determining priorities, identifying barriers and facilitators for change, understanding processes of mobilizing knowledge in relation to context, determining appropriate communication approaches, and integrating indigenous language and cultural perspectives into communication concepts. Emerging communication strategies include support to systematic action and long-term mobilization. Communication to address public health concerns is typically

    Full Text Available To review trends in non-communicable (NCD research output in the Arab region, in terms of quantity and quality, study design, setting and focus. We also examined differences by time and place, and assessed gaps between research output and NCD burden.A scoping review of a total of 3,776 NCD-related reports published between 2000 and 2013 was conducted for seven Arab countries. Countries were selected to represent diverse socio-economic development levels in the region: Regression analyses were used to assess trends in publications over time and by country. Research gaps were assessed by examining the degree of match between proportionate literature coverage of the four main NCDs (CVD, cancer, DM, and COPD and cause-specific proportional mortality rates (PMR.The annual number of NCD publications rose nearly 5-fold during the study period, with higher income countries having the higher publication rates (per million populations and the most rapid increases. The increase in the publication rate was particularly prominent for descriptive observational studies, while interventional studies and systematic reviews remained infrequent (slope coefficients = 13.484 and 0.883, respectively. Gap analysis showed a mismatch between cause-specific PMR burden and NCD research output, with a relative surplus of reports on cancer (pooled estimate +38.3% and a relative deficit of reports on CVDs (pooled estimate -30.3%.The widening disparity between higher and lower-income countries and the discordance between research output and disease burden call for the need for ongoing collaboration among Arab academic institutions, funding agencies and researchers to guide country-specific and regional research agendas, support and conduct.

    2007-12-01

    In May 2007 the Open University (U.K.) in conjunction with the MK (Milton Keynes) Gallery invited performance artists Noble and Silver to work with a group of students to design innovative methods of disseminating their research to a general audience. The students created a multitude of well-received live and multimedia performances based on their research. Students found they greatly benefited from the artists' and each others' different viewpoints and backgrounds, resulting in improved communication skills and varying interpretations of their own topic of interest. This work focuses on research aimed at identifying precursory activity at volcanoes using temperature, earthquake and ground movement data, to aid improvement of early warning systems. For this project an aspect of the research relevant to the public was chosen: the importance of appropriately timed warnings regarding the possibility of an eruption. If a warning is issued too early it may cause complacency and apathy towards the situation, whereas issuing a warning too late may endanger lives and property. An interactive DVD was produced which leads the user through the events preceding a volcanic eruption. The goal is to warn the public about the impending eruption at the most appropriate time. Data is presented in short film clips, after which questions are posed. Based on the player's answers the consequences or follow-up events of the choices are explored. We aim to improve and expand upon this concept in the near future, as well as making the DVD available to schools for educational purposes.

    In order to investigate the relationship between lipid structure and liposome-mediated gene transfer, we have studied biophysical parameters and transfection properties of monocationic DOTAP analogs, systematically modified in their non-polar hydrocarbon chains. Stability, size and (by means of anisotropy profiles) membrane fluidity of liposomes and lipoplexes were determined, and lipofection efficiency was tested in a luciferase reporter gene assay. DOTAP analogs were used as single components or combined with a helper lipid, either DOPE or cholesterol. Stability of liposomes was a precondition for formation of temporarily stable lipoplexes. Addition of DOPE or cholesterol improved liposome and lipoplex stability. Transfection efficiencies of lipoplexes based on pure DOTAP analogs could be correlated with stability data and membrane fluidity at transfection temperature. Inclusion of DOPE led to rather uniform transfection and anisotropy profiles, corresponding to lipoplex stability. Cholesterol-containing lipoplexes were generally stable, showing high transfection efficiency at low relative fluidity. Our results demonstrate that the efficiency of gene transfer mediated by monocationic lipids is greatly influenced by lipoplex biophysics due to lipid composition. The measurement of fluorescence anisotropy is an appropriate method to characterize membrane fluidity within a defined system of liposomes or lipoplexes and may be helpful to elucidate structure-activity relationships.

    Research about the effectiveness of communicative supports and advances in photographic technology has prompted changes in the way speech-language pathologists design and implement interventions for people with aphasia. The purpose of this paper is to describe the use of photographic images as a basis for developing communication supports for people with chronic aphasia secondary to sudden-onset events due to cerebrovascular accidents (strokes). Topics include the evolution of AAC-based supports as they relate to people with aphasia, the development and key features of visual scene displays (VSDs), and future directions concerning the incorporation of photographs into communication supports for people with chronic and severe aphasia.

    Telecommunications in Australia has expanded rapidly in recent years. Growth in personal and mobile telecommunications has resulted in the construction of numerous base station antennae. These antennae are highly visible and are often sited in public or high traffic areas. There has also been an increase in the number of mobile phone handsets-the small, low power transmitters held close to the head during use. In the last 2-3 years there has been considerable public concern and media coverage about the possible health effects resulting from exposure to radiofrequency fields or radiofrequency radiation (RFR) which is used for communicating between handsets and base stations. National and international scientific opinion is that at the present time there is no substantiated evidence that exposure to RFR at levels typically found in the community results in adverse health effects but there is a need for further study. Although considerable research has been undertaken on exposure to extremely low frequency (ELF) 50/60 Hz fields, limited information is available on human exposure to RFR in the frequency range 100 kHz to 300 GHz. The frequency bands used for the mobile phone networks are mainly in the 800-900 MHz spectrum region with developing technology using the 1.8-2.2 GHz band. In the digital GSM system pulse modulation occurs at 217 Hz. Radio and television broadcasts are in the 0.3-600 MHz range. Other sources include paging systems, personal communication systems and industrial sources. The discussion paper outlines possible priority areas and makes recommendation for further study under the Australian Research Program

    Photodynamic therapy (PDT) uses light-activated drugs to treat diseases ranging from cancer to age-related macular degeneration and antibiotic-resistant infections. This paper reviews the current status of PDT with an emphasis on the contributions of physics, biophysics and technology, and the challenges remaining in the optimization and adoption of this treatment modality. A theme of the review is the complexity of PDT dosimetry due to the dynamic nature of the three essential components-light, photosensitizer and oxygen. Considerable progress has been made in understanding the problem and in developing instruments to measure all three, so that optimization of individual PDT treatments is becoming a feasible target. The final section of the review introduces some new frontiers of research including low dose rate (metronomic) PDT, two-photon PDT, activatable PDT molecular beacons and nanoparticle-based PDT.

  6. The utilization of research-based information: Moving beyond communicating assessments of (climate) impacts

    2006-12-01

    Societal impacts of changing environments include primary or direct effects (increased soil moisture, loss of life, crop and building damage etc.), secondary or indirect effects (displacement, illness) and, higher order or systemic effects (debt, loss of livelihood). Vulnerability to such events is constructed from: (1) the timing, magnitude, spatial extent, and duration of the physical hazard i.e. risk of occurrence; (2) exposure in regions of risk e.g. population, property; and, (3) factors that pre-condition the degree of impact and the capacity to respond and recover. The call for better articulated decision support and services components is rising on par with more traditional axes of assessments i.e. characterizing the integrated physical system and its social and environmental impacts. The expectation is that increasing the rate at which policy makers and resource managers acquire knowledge about environment-society interactions will result in improvements in the quality of public and private decisions (a decidedly idealized view). Much recent work has shown that this expectation is most difficult to meet when decision stakes are high, uncertainty is great, technologies are new, experience is limited, and there are unequal distributions of burdens and benefits. We review generalized frames of reference on the use of climate information identified in independent studies undertaken by the authors in different river basins of North America. As shown in these (and other) studies, researchers, policy-makers and practitioners (public and private) operate on different time-lines, use different languages, and most importantly respond to different problem definitions and accountability incentives. The process of communication is increasingly recognized to be complex, transactional, and heavily dependent on the potential user's pre-existing knowledge, beliefs and experiences. We outline differing approaches to risk communication and their associated assumptions

  11. Drought propagation and its relation with catchment biophysical characteristics

    2016-12-01

    Droughts propagate in the hydrological cycle from meteorological to soil moisture to hydrological droughts. To understand the drivers of this process is of paramount importance since the economic and societal impacts in water resources are directly related with hydrological droughts (and not with meteorological droughts, which have been most studied). This research analyses drought characteristics over a large region and identify its main exogenous (climate forcing) and endogenous (biophysical characteristics such as land cover type and topography) explanatory factors. The study region is Chile, which covers seven major climatic subtypes according to Köppen system, it has unique geographic characteristics, very sharp topography and a wide range of landscapes and vegetation conditions. Meteorological and hydrological droughts (deficit in precipitation and streamflow, respectively) are characterized by their durations and standardized deficit volumes using a variable threshold method, over 300 representative catchments (located between 27°S and 50°S). To quantify the propagation from meteorological to hydrological drought, we propose a novel drought attenuation index (DAI), calculated as the ratio between the meteorological drought severity slope and the hydrological drought severity slope. DAI varies from zero (catchment that attenuates completely a meteorological drought) to one (the meteorological drought is fully propagated through the hydrological cycle). This novel index provides key (and comparable) information about drought propagation over a wide range of different catchments, which has been highlighted as a major research gap. Similar drought indicators across the wide range of catchments are then linked with catchment biophysical characteristics. A thorough compilation of land cover information (including the percentage of native forests, grass land, urban and industrial areas, glaciers, water bodies and no vegetated areas), catchment physical

  12. A synthesized biophysical and social vulnerability assessment for Taiwan

    2017-11-01

    Taiwan, located in the Western Pacific, is a country that is one of the most vulnerable to disasters that are associated with the changing climate; it is located within the Ring of Fire, which is the most geologically active region in the world. The environmental and geological conditions in Taiwan are sensitive and vulnerable to such disasters. Owing to increasing urbanization in Taiwan, floods and climate-related disasters have taken an increasing toll on human lives. As global warming accelerates the rising of sea levels and increasing of the frequency of extreme weather events, disasters will continue to affect socioeconomic development and human conditions. Under such circumstances, researchers and policymakers alike must recognize the importance of providing useful knowledge concerning vulnerability, disaster recovery and resilience. Strategies for reducing vulnerability and climate-related disaster risks and for increasing resilience involve preparedness, mitigation and adaptation. In the last two decades, extreme climate events have caused severe flash floods, debris flows, landslides, and other disasters and have had negative effects of many sectors, including agriculture, infrastructure and health. Since climate change is expected to have a continued impact on socio-economic development, this work develops a vulnerability assessment framework that integrates both biophysical and social vulnerability and supports synthesized vulnerability analyses to identify vulnerable areas in Taiwan. Owing to its geographical, geological and climatic features, Taiwan is susceptible to earthquakes, typhoons, droughts and various induced disasters. Therefore, Taiwan has the urgent task of establishing a framework for assessing vulnerability as a planning and policy tool that can be used to identify not only the regions that require special attention but also hotspots in which efforts should be made to reduce vulnerability and the risk of climate-related disaster.

    In order to provide a meaningful context for non-technical users to be able to decipher and comprehend research data, it is necessary to provide background into the process involved. Storytelling can provide the narrative description that brings data alive by showing the 'Who' (providing human interest, education and training background, and career opportunities information), 'What' (focusing on discipline, field of study, research questions, and significance), 'Where' (geographic location(s), logistics involved in getting there, and elevation or depth), 'When' (time(s) of day, year data collected, and temporal scale data focus on), 'Why' (why is the data important intellectually as well as in the broader, societal context) and especially the 'How' (what tools, technology, mathematics, and statistics are used to collect, archive, and analyze data). The upcoming International Polar Year (IPY), running from March 2007 to March 2009, builds on prior polar research and IPYs, and offers a unique opportunity to showcase the process of data collection and analysis in a compelling human context. Internationally, the IPY Education, Outreach and Communication (EOC) subcommittee is seeking to integrate the EOC continuum and when appropriate repurpose information about specific research projects. For example, descriptions of projects designed initially for media purposes may also serve as the "at a glance" overview of a project that can then link to more detailed narrative descriptions of the projects, augmented with video and audio clips, web-links to related background information and relevant curriculum, and ultimately to the data itself, well scaffolded with relevant supporting materials and tools. In the United States, plans are underway for developing a suite of data stories that provide the narrative background of a project and can be used in museum kiosks and other informal science settings, data sheets, that provide teachers with an overview of the data, and

    The intersections between identity and health communication are complex and dynamic, yet few studies employ a critical-empirical research strategy to understand how these factors affect patient experiences. And although other disciplines have examined lesbian, gay, bisexual, transgendered, and queer (LGBTQ)-specific issues surrounding identity and health care, there is a gap in communication studies literature on the topic. The present study examines how LGBTQ patients experience the language and structure of medical intake forms by analyzing both existing forms and patient survey responses. Relying on a queer theory framework, we illustrate how intake forms can foreclose on LGBTQ identity with heteronormative assumptions about sexuality, gender, and relationships. We also offer recommendations for creating queer-friendly intake forms and avoiding heteronormativity in health communication research. Overall, we argue that researchers must use reflexive methodology in considering how identity categories can both limit and assist LGBTQ patients.

    The rapid development of new media has exacerbated the complexity of urban street space’s information interaction. With the influence of the immersion communication, the streetscape has constructed a special scene like ‘media convergence’, which has brought a huge challenge for maintaining the urban streetscape order. The Spatial Visual Communication Research Method which should break the limitation of the traditional aesthetic space research, can provide a brand new prospect for this phenomenon research. This study aims to analyze and summarize the communication characteristics of new media and its context, which will be helpful for understanding the social meaning within the order change of the street’s spatial and physical environment.

    There are many challenges to the drug discovery process, including the complexity of the target, its interactions, and how these factors play a role in causing the disease. Traditionally, biophysics has been used for hit validation and chemical lead optimization. With its increased throughput and sensitivity, biophysics is now being applied earlier in this process to empower target characterization and hit finding. Areas covered: In this article, the authors provide an overview of how biophysics can be utilized to assess the quality of the reagents used in screening assays, to validate potential tool compounds, to test the integrity of screening assays, and to create follow-up strategies for compound characterization. They also briefly discuss the utilization of different biophysical methods in hit validation to help avoid the resource consuming pitfalls caused by the lack of hit overlap between biophysical methods. Expert opinion: The use of biophysics early on in the drug discovery process has proven crucial to identifying and characterizing targets of complex nature. It also has enabled the identification and classification of small molecules which interact in an allosteric or covalent manner with the target. By applying biophysics in this manner and at the early stages of this process, the chances of finding chemical leads with novel mechanisms of action are increased. In the future, focused screens with biophysics as a primary readout will become increasingly common.

    The reasons for performing experiments in radiation biophysics at low temperatures, whereby electron spectra may be studied, are explained. The phenomenon of phosphorescence spectra observed in frozen aqueous solutions of tryptophan and adenosine is also described. Free radicals play an important part in biological radiation effects and may be studied by ESR spectroscopy. An ESR spectrum of T 1 bacteriophages irradiated dry at 130K is illustrated and discussed. Hydrogen atoms, which give lines on the spectrum, are believed to be those radiation products causing most biological damage in a dry system. Low temperature experiments are of great help in explaining the significance of direct and indirect effects. This is illustrated for the case of trypsin. (JIW)

  19. Biophysical mechanisms complementing "classical" cell biology.

    Science.gov (United States)

    Funk, Richard H W

    2018-01-01

    This overview addresses phenomena in cell- and molecular biology which are puzzling by their fast and highly coordinated way of organization. Generally, it appears that informative processes probably involved are more on the biophysical than on the classical biochemical side. The coordination problem is explained within the first part of the review by the topic of endogenous electrical phenomena. These are found e.g. in fast tissue organization and reorganization processes like development, wound healing and regeneration. Here, coupling into classical biochemical signaling and reactions can be shown by modern microscopy, electronics and bioinformatics. Further, one can follow the triggered reactions seamlessly via molecular biology till into genetics. Direct observation of intracellular electric processes is very difficult because of e.g. shielding through the cell membrane and damping by other structures. Therefore, we have to rely on photonic and photon - phonon coupling phenomena like molecular vibrations, which are addressed within the second part. Molecules normally possess different charge moieties and thus small electromagnetic (EMF) patterns arise during molecular vibration. These patterns can now be measured best within the optical part of the spectrum - much less in the lower terahertz till kHz and lower Hz part (third part of this review). Finally, EMFs facilitate quantum informative processes in coherent domains of molecular, charge and electron spin motion. This helps to coordinate such manifold and intertwined processes going on within cells, tissues and organs (part 4). Because the phenomena described in part 3 and 4 of the review still await really hard proofs we need concerted efforts and a combination of biophysics, molecular biology and informatics to unravel the described mysteries in "physics of life".

    2010-09-01

    The article examines the use of newer, interactive information and communication technologies (ICTs) in young men's health promotion (HP), drawing on gender theory, HP research and evidence on young men's Internet usage. The focus is on highlighting an agenda for research in terms of emerging issues. New forms of social media ICT (for example 'web 2'-based on-line social networking sites, micro-blogging services, i-phones and podcasts) have the potential to enable young men to engage with health information in new and interesting ways. Given concerns about young men's engagement with health services, innovative ICT formats, particularly using the Internet, have been tried. However, issues persist around surfing 'addiction', quality control and equal access. Approaches to HP using new ICTs offer distributed control over information content and quality and a lay social context for accessing information. Online communities can potentially legitimize young men's participation in discourses around health, and support sustained engagement. The article discusses how this could support young men to re-conceptualize healthy choices in the context of masculine imperatives and responsible citizenship if specific conditions are met (for trusting engagement) and risks addressed (such as commercial disinformation). The skill requirements for young men to engage effectively with new ICTs are explored, focusing on health literacy (HL). It is predicted that social marketing approaches to HP for young men will increasingly include new ICTs, making specific requirements for HL. These approaches may appeal narrowly to hegemonic masculinities or broadly to multiple masculinities, including those historically marginalized. Recommendations are made for future research.

    In the satellite to earth laser communication link, large-aperture ground laser communication terminals usually are used in order to realize the requirement of high rate and long distance communication and restrain the power fluctuation by atmospheric scintillation. With the increasing of the laser communication terminal caliber, the primary mirror weight should also be increased, and selfweight, thermal deformation and environment will affect the surface accuracy of the primary mirror surface. A high precision vehicular laser communication telescope unit with an effective aperture of 600mm was considered in this paper. The primary mirror is positioned with center hole, which back is supported by 9 floats and the side is supported by a mercury band. The secondary mirror adopts a spherical adjusting mechanism. Through simulation analysis, the system wave difference is better than λ/20 when the primary mirror is in different dip angle, which meets the requirements of laser communication.

    In order to reduce the inconsistencies of findings and the apparent low transfer of communication skills from training to medical practice, this narrative review identifies some main gaps in research on medical communication skills training and presents insights from theories on learning and transfer to broaden the view for future research. Relevant literature was identified using Pubmed, GoogleScholar, Cochrane database, and Web of Science; and analyzed using an iterative procedure. Research findings on the effectiveness of medical communication training still show inconsistencies and variability. Contemporary theories on learning based on a constructivist paradigm offer the following insights: acquisition of knowledge and skills should be viewed as an ongoing process of exchange between the learner and his environment, so called lifelong learning. This process can neither be atomized nor separated from the context in which it occurs. Four contemporary approaches are presented as examples. The following shift in focus for future research is proposed: beyond isolated single factor effectiveness studies toward constructivist, non-reductionistic studies integrating the context. Future research should investigate how constructivist approaches can be used in the medical context to increase effective learning and transition of communication skills.

    Operational conjectures about space exploration missions of the future indicate that space crews will need to be more autonomous from mission control and operate independently. This is in part due to the expectation that communication quality between the ground and exploration crews will be more limited and delayed. Because of potential adverse effects on communication quality, both researchers and operational training and engineering experts have suggested that communication delays and the impact these delays have on the quality of communications to the crew will create performance decrements if crews are not given adequate training and tools to support more autonomous operations. This presentation will provide an overview of a research study led by the Behavioral Health and Performance Element (BHP) of the NASA Human Research Program that examines the impact of implementing a communication delay on ISS on individual and team factors and outcomes, including performance and related perceptions of autonomy. The methodological design, data collection efforts, and initial results of this study to date will be discussed . The results will focus on completed missions, DRATS and NEEMO15. Lessons learned from implementing this study within analog environments will also be discussed. One lesson learned is that the complexities of garnishing a successful data collection campaign from these high fidelity analogs requires perseverance and a strong relationship with operational experts. Results of this study will provide a preliminary understanding of the impact of communication delays on individual and team performance as well as an insight into how teams perform and interact in a space-like environment . This will help prepare for implementation of communication delay tests on the ISS, targeted for Increment 35/36.

  8. Constructing Precisely Computing Networks with Biophysical Spiking Neurons.

    While spike timing has been shown to carry detailed stimulus information at the sensory periphery, its possible role in network computation is less clear. Most models of computation by neural networks are based on population firing rates. In equivalent spiking implementations, firing is assumed to be random such that averaging across populations of neurons recovers the rate-based approach. Recently, however, Denéve and colleagues have suggested that the spiking behavior of neurons may be fundamental to how neuronal networks compute, with precise spike timing determined by each neuron's contribution to producing the desired output (Boerlin and Denéve, 2011; Boerlin et al., 2013). By postulating that each neuron fires to reduce the error in the network's output, it was demonstrated that linear computations can be performed by networks of integrate-and-fire neurons that communicate through instantaneous synapses. This left open, however, the possibility that realistic networks, with conductance-based neurons with subthreshold nonlinearity and the slower timescales of biophysical synapses, may not fit into this framework. Here, we show how the spike-based approach can be extended to biophysically plausible networks. We then show that our network reproduces a number of key features of cortical networks including irregular and Poisson-like spike times and a tight balance between excitation and inhibition. Lastly, we discuss how the behavior of our model scales with network size or with the number of neurons "recorded" from a larger computing network. These results significantly increase the biological plausibility of the spike-based approach to network computation. We derive a network of neurons with standard spike-generating currents and synapses with realistic timescales that computes based upon the principle that the precise timing of each spike is important for the computation. We then show that our network reproduces a number of key features of cortical networks

    Since the discovery of early infantile autism (1943), the etiology of the disease has for long been a matter of dispute-from a form of innate schizophrenia, maltreatment by 'refrigerator mother', to dysfunction of speech development. After the re-discovery of Asperger syndrome by Wing (1981), the concept of this diverse syndrome complex has merged to pervasive developmental disorders (PDD) or autism spectrum disorders (ASD). People suffering from Asperger syndrome do not show impairments in speech development, in fact, they have good linguistic abilities. They can explain their own psychopathology, which helps in the understanding of classical autism with profound mental retardation. Currently, ASD is prevalent in 1 of 150 births with strong genetic inheritance. ASD is therefore thought a psychiatric common disease. Asperger syndrome has frequently been the subject of neuroimaging studies, since social communication is an important characteristic of human behavior. This review encompasses a historical and clinical overview of ASD and puts force the current perspectives on the researches in animal models, genetic studies of animal and human samples, and neuroimaging studies. Our current focus is the possible role of oxytocin, which was recently found to have an effect on empathy, in the etiology of ASD. (author)

  10. Why Health Care Needs Design Research: Broadening the Perspective on Communication in Pediatric Care Through Play.

    Today's pediatric health care lacks methods to tap into the emotional state of hospitalized pediatric patients (age 4-6 years). The most frequently used approaches were developed for adults and fail to acknowledge the importance of imaginary experiences and the notion of play that may appeal to children. The scope of this article is to introduce a new design-oriented method of gathering information about the emotional state of pediatric patients using an experimental computer game called the Child Patient game (CPgame). The CPgame was developed at a Danish hospital, and the results of the preliminary tests show that games could serve as a system in which children are willing to express their emotions through play. The results are based on two comparative analyses of the CPgame through which it is possible to identify three different types of players among the patients playing the game. Furthermore, the data reveal that pediatric patients display a radically different play pattern than children who are not in hospital. The inquiry takes an interdisciplinary approach; it has obvious health care-related objectives and seeks to meet the urgent need for new methods within health care to optimize communication with young children. At the same time, design research (i.e., the development of new knowledge through the development of a new design) heavily impacts the method.

  11. Action research, simulation, team communication, and bringing the tacit into voice society for simulation in healthcare.

    In healthcare, professionals usually function in a time-constrained paradigm because of the nature of care delivery functions and the acute patient populations usually in need of emergent and urgent care. This leaves little, if no time for team reflection, or team processing as a collaborative action. Simulation can be used to create a safe space as a structure for recognition and innovation to continue to develop a culture of safety for healthcare delivery and patient care. To create and develop a safe space, three qualitative modified action research institutional review board-approved studies were developed using simulation to explore team communication as an unfolding in the acute care environment of the operating room. An action heuristic was used for data collection by capturing the participants' narratives in the form of collaborative recall and reflection to standardize task, process, and language. During the qualitative simulations, the team participants identified and changed multiple tasks, process, and language items. The simulations contributed to positive changes for task and efficiencies, team interactions, and overall functionality of the team. The studies demonstrated that simulation can be used in healthcare to define safe spaces to practice, reflect, and develop collaborative relationships, which contribute to the realization of a culture of safety.

    An action research project called dialogue forum has been conducted in this study. The essential constituent of the project is a series of repetitive dialogue sessions carried out by lay citizens, nuclear experts, and a facilitator. One important feature of the project is that the study has been conducted based on the qualitative research methodology. The changes in opinions and attitude of the dialogue participants have been analyzed by an ethno-methodological approach. The observations are summarized as follows. The opinions of the citizen participants showed a significant shift from emotional to practical representations along with the progression of the dialogue sessions. Meanwhile, their attitude showed a marked tendency from problem-statement-oriented to problem-solving-oriented representation. On the other hand, the statements of the expert participants showed a significant shift from expert-based to citizen-based risk recognition and description, and their attitude showed a clear tendency from teaching-oriented to colearning-oriented thinking. These changes of opinions and attitude have been interpreted as a coevolving rather than a single process. It can be stressed that this type of change is most important for the reestablishment of mutual trust between the citizens and the nuclear experts. In this regard The Process Model of Coevolution of Risk Recognition' has been proposed as a guideline for developing a new scheme of public communication concerning nuclear technology. The proposed process model of coevolution of risk recognition is regarded to be essential for appropriate relationship management between nuclear technology and society in the near future. (author)

    This study describes the sexual knowledge and communication of Mexican parents and adolescents. Preintervention data were analyzed from 829 high school students (ages 14-17) and one of the parents of each. Differences were found between parents and adolescents in sexual knowledge (M = 16.16 vs. M = 14.92; t = 7.20, p knowledge related to sexually transmitted diseases, HIV/AIDS, and condom use. Parents perceived more general communication (t [787] = 6.33, p education levels scored higher in HIV knowledge and general communication. Fathers had higher total sexual knowledge, whereas mothers perceived higher sexual communication than fathers. There were no differences in knowledge and communication by parental socioeconomic level. Results suggest health care providers need to assist parents in developing specific knowledge and skills to support their adolescents' sexual decision-making.

    The digital revolution is changing the manner in which patients communicate with their health care providers, yet many patients still lack access to communication technology. We conducted this study to evaluate access to, use of, and preferences for using communication technology among a predominantly low-income patient population. We determined whether access, use, and preferences were associated with type of health insurance, sex, age, and ethnicity. In 2011, medical student researchers administered questionnaires to patients of randomly selected physicians within 9 primary care clinics in the Residency Research Network of Texas. Surveys addressed access to and use of cell phones and home computers and preferences for communicating with health care providers. In this sample of 533 patients (77% response rate), 448 (84%) owned a cell phone and 325 (62%) owned computers. Only 48% reported conducting Internet searches, sending and receiving E-mails, and looking up health information on the Internet. Older individuals, those in government sponsored insurance programs, and individuals from racial/ethnic minority groups had the lowest levels of technology adoption. In addition, more than 60% of patients preferred not to send and receive health information over the Internet, by instant messaging, or by text messaging. Many patients in this sample did not seek health information electronically nor did they want to communicate electronically with their physicians. This finding raises concerns about the vision of the patient-centered medical home to enhance the doctor-patient relationship through communication technology. Our patients represent some of the more vulnerable populations in the United States and, as such, deserve attention from health care policymakers who are promoting widespread use of communication technology.

    Full Text Available The completion of a master’s thesis requires the advisor’s guidance on topic selection, data collection, analysis, interpretation and writing. The advisory committee’s input also contributes to the work. This study conducted content analysis and network analysis on a sample of 547 master’s theses from eight departments of the College of Journalism and Communications of Shih Hsin University to examine the relationships between the advisors and committee members as well as the connections of research topics. The results showed that the topic “lifestyle” have attracted cross-department research interests in the college. The academic network of the college is rather loose, and serving university administration duties may have broadened a faculty member’s centrality in the network. The Department of Communications Management and the Graduate Institute of Communications served as the bridges for the inter-departmental communication in the network. One can understand the interrelations among professors and departments through study on network analysis of thesis as to identify the characteristics of each department, as well as to reveal invisible relations of academic network and scholarly communication.

    Oprisan, Sorinel

    2008-03-01

    We proposed and studied a new biophysically relevant computational model of dopaminergic neurons. Midbrain dopamine neurons are involved in motivation and the control of movement, and have been implicated in various pathologies such as Parkinson's disease, schizophrenia, and drug abuse. The model we developed is a single-compartment Hodgkin-Huxley (HH)-type parallel conductance membrane model. The model captures the essential mechanisms underlying the slow oscillatory potentials and plateau potential oscillations. The main currents involved are: 1) a voltage-dependent fast calcium current, 2) a small conductance potassium current that is modulated by the cytosolic concentration of calcium, and 3) a slow voltage-activated potassium current. We developed multidimensional bifurcation diagrams and extracted the effective domains of sustained oscillations. The model includes a calcium balance due to the fundamental importance of calcium influx as proved by simultaneous electrophysiological and calcium imaging procedure. Although there are significant evidences to suggest a partially electrogenic calcium pump, all previous models considered only elecrtogenic pumps. We investigated the effect of the electrogenic calcium pump on the bifurcation diagram of the model and compared our findings against the experimental results.

  15. Biophysical and biomathematical adventures in radiobiology

    Highlights of my biophysical and biomathematical adventures in radiobiology is presented. Early adventures involved developing ''state-vector models'' for specific harmful effects (cell killing, life shortening) of exposure to radiation. More recent adventures led to developing ''hazard-function models'' for predicting biological effects (e.g., cell killing, mutations, tumor induction) of combined exposure to different toxicants. Hazard-function models were also developed for predicting harm to man from exposure to large radiation doses. Major conclusions derived from the modeling adventures are as follows: (1) synergistic effects of different genotoxic agents should not occur at low doses; (2) for exposure of the lung or bone marrow to large doses of photon radiation, low rates of exposure should be better tolerated than high rates; and (3) for some types of radiation (e.g., alpha particles and fission neutrons), moderate doses delivered at a low rate may be more harmful than the same dose given at a high rate. 53 refs., 7 figs

    2009-01-01

    The Famine Early Warning System Network (FEWS NET) provides monitoring and early warning support to decision makers responsible for responding to famine and food insecurity. FEWS NET transforms satellite remote sensing data into rainfall and vegetation information that can be used by these decision makers. The National Aeronautics and Space Administration has recently funded activities to enhance remote sensing inputs to FEWS NET. To elicit Earth observation requirements, a professional review questionnaire was disseminated to FEWS NET expert end-users: it focused upon operational requirements to determine additional useful remote sensing data and; subsequently, beneficial FEWS NET biophysical supplementary inputs. The review was completed by over 40 experts from around the world, enabling a robust set of professional perspectives to be gathered and analyzed rapidly. Reviewers were asked to evaluate the relative importance of environmental variables and spatio-temporal requirements for Earth science data products, in particular for rainfall and vegetation products. The results showed that spatio-temporal resolution requirements are complex and need to vary according to place, time, and hazard: that high resolution remote sensing products continue to be in demand, and that rainfall and vegetation products were valued as data that provide actionable food security information.

  17. Biophysical Aspects of Radiation Quality. Second Panel Report

    International Nuclear Information System (INIS)

    1968-01-01

    If a living system is exposed to ionizing radiation a sequence of events follows. It starts with the absorption and dissipation of radiation energy, and continues through various physico-chemical and biochemical reactions up to the final biological end point observed. One of the aims of research in quantitative radiation biology is to understand the mechanism of this sequence of actions and to explore the differences in quality of different kinds of radiations. Because of its complexity, progress in this work requires the combined efforts of physicists, biochemists, biologists and physicians. It should, however, be done in very close collaboration rather than in following isolated lines in any one direction. For this reason, and because of the growing importance of the field for almost all applications of ionizing radiations, it was felt desirable to bring together a group of scientists engaged in research on radiation quality who represented a wide range of interests. The first panel on Biophysical Aspects of Radiation Quality, convened by the International Atomic Energy Agency in Vienna and held from 29 March to 2 April 1965, proved to be a successful beginning, stimulating a useful exchange of ideas and information. By this meeting, and the resulting collection of papers, published in 1966 as No. 58 of the Agency's Technical Reports Series, the importance of research on radiation quality was highlighted and the field itself became more clearly defined. The Agency held a second Panel on the same subject in Vienna from 14 to 18 April 1967. This meeting was attended by 18 experts from 10 countries, and representatives from Euratom and WHO. The Czechoslovak Socialist Republic, France, India and Poland were represented for the first time. Fourteen papers were presented and discussed in some detail. It became evident that much progress had been made since the previous meeting in certain areas such as microdosimetry, the dependence of the oxygen effect on radiation

    The increasing amount of the clinical research conducted in the primary health care has enabled extending research beyond traditional settings, but this transfer has implied some trade-offs. Health care professionals who conduct research with trusted patients require assuming the ethical standards of research and communication skills to enable patients' autonomy and freedom of choice. This study aims to measure the opinions of health professionals and patients on issues of communication in clinical research. A cross-sectional study with health care professionals and patients from primary health care centres in Barcelona (Spain). Each group completed a similar self-administered questionnaire. A Rasch model was fitted to data. After examination of goodness-of-fit, differences between groups were compared using analysis of variance, and patients' measures were calibrated to professionals' measures to compare overall mean measures. Professionals and patients found the ethical attitudes most difficult to endorse related to trust in clinical researchers and conflicts of interest. Patients' perceptions of professional ethical behaviour were significantly lower than professionals'. Different item functioning between nurses and family doctors was found in the item on seeking ethical collaboration when collaborating in clinical research. Effective knowledge of ethical norms was associated with greater perceived ethical values in clinical research and confidence in health care professionals among patients. Differences in the views of the communication process between patients and professionals could alert research boards, health care institutions and researchers to the need for greater transparency, trust and ethical instruction when patients are involved in clinical research. © 2015 John Wiley & Sons, Ltd.

  19. Linking biophysical models and public preferences for ecosystem service assessments: a case study for the Southern Rocky Mountains

    Through extensive research, ecosystem services have been mapped using both survey-based and biophysical approaches, but comparative mapping of public values and those quantified using models has been lacking. In this paper, we mapped hot and cold spots for perceived and modeled ecosystem services by synthesizing results from a social-values mapping study of residents living near the Pike–San Isabel National Forest (PSI), located in the Southern Rocky Mountains, with corresponding biophysically modeled ecosystem services. Social-value maps for the PSI were developed using the Social Values for Ecosystem Services tool, providing statistically modeled continuous value surfaces for 12 value types, including aesthetic, biodiversity, and life-sustaining values. Biophysically modeled maps of carbon sequestration and storage, scenic viewsheds, sediment regulation, and water yield were generated using the Artificial Intelligence for Ecosystem Services tool. Hotspots for both perceived and modeled services were disproportionately located within the PSI’s wilderness areas. Additionally, we used regression analysis to evaluate spatial relationships between perceived biodiversity and cultural ecosystem services and corresponding biophysical model outputs. Our goal was to determine whether publicly valued locations for aesthetic, biodiversity, and life-sustaining values relate meaningfully to results from corresponding biophysical ecosystem service models. We found weak relationships between perceived and biophysically modeled services, indicating that public perception of ecosystem service provisioning regions is limited. We believe that biophysical and social approaches to ecosystem service mapping can serve as methodological complements that can advance ecosystem services-based resource management, benefitting resource managers by showing potential locations of synergy or conflict between areas supplying ecosystem services and those valued by the public.

  20. Effects of LiDAR point density, sampling size and height threshold on estimation accuracy of crop biophysical parameters.

    Vegetation leaf area index (LAI), height, and aboveground biomass are key biophysical parameters. Corn is an important and globally distributed crop, and reliable estimations of these parameters are essential for corn yield forecasting, health monitoring and ecosystem modeling. Light Detection and Ranging (LiDAR) is considered an effective technology for estimating vegetation biophysical parameters. However, the estimation accuracies of these parameters are affected by multiple factors. In this study, we first estimated corn LAI, height and biomass (R2 = 0.80, 0.874 and 0.838, respectively) using the original LiDAR data (7.32 points/m2), and the results showed that LiDAR data could accurately estimate these biophysical parameters. Second, comprehensive research was conducted on the effects of LiDAR point density, sampling size and height threshold on the estimation accuracy of LAI, height and biomass. Our findings indicated that LiDAR point density had an important effect on the estimation accuracy for vegetation biophysical parameters, however, high point density did not always produce highly accurate estimates, and reduced point density could deliver reasonable estimation results. Furthermore, the results showed that sampling size and height threshold were additional key factors that affect the estimation accuracy of biophysical parameters. Therefore, the optimal sampling size and the height threshold should be determined to improve the estimation accuracy of biophysical parameters. Our results also implied that a higher LiDAR point density, larger sampling size and height threshold were required to obtain accurate corn LAI estimation when compared with height and biomass estimations. In general, our results provide valuable guidance for LiDAR data acquisition and estimation of vegetation biophysical parameters using LiDAR data.
