    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...

    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

  6. Biophysical research requirements for Beaufort Sea hydrocarbon development

    Energy Technology Data Exchange (ETDEWEB)



    This review identified biophysical research requirements and data gaps for the development of hydrocarbon resources in the Beaufort Sea. The potential major effects of critical activities during each phase of the offshore oil and gas development cycle were identified in order to assess the impacts on local communities and traditional harvesting methods. Baseline environmental conditions were established. Information needs were ranked using 3 criteria: (1) the current understanding of the biophysical component in terms of present status and long-term sustainability, (2) the potential impact of the oil and gas development on the long-term sustainability of the biophysical component, and (3) the timeline for completion of the research relative to the expected development for the Beaufort Sea region. Mitigation and environmental management plans were outlined, and key research, data collection, and data analyses required to address data gaps were identified. Previous gap analyses for the region were reviewed. Data from a series of workshops conducted with various stakeholders were also included in the study. High research priorities include the assessment of the effects of climatic change on the physical oceanography of the region, studies on deepwater plankton, benthos, and fish. It was concluded that studies are needed to determine the effects of development on marine mammals, avifauna, and macroalgae. 207 refs., 49 tabs., 4 figs.

  9. Developing a physics expert identity in a biophysics research group (United States)

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


    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.

  10. The Colorado Plateau II: biophysical, socioeconomic, and cultural research (United States)

    Mattson, David J.; van Riper, Charles


    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.

  1. Health communication: lessons from research. (United States)

    Shanmugam, A V


    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

  3. Novel physical chemistry approaches in biophysical researches with advanced application of lasers: Detection and manipulation. (United States)

    Iwata, Koichi; Terazima, Masahide; Masuhara, Hiroshi


    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

  14. The BIOMAT facility at FAIR: a new tool for ground-based research in space radiation biophysics (United States)

    Durante, Marco

    The BIOMAT facility at FAIR: a new tool for ground-based research in space radiation biophysics M.Durante The FAIR accelerator complex at GSI (placeCityDarmstadt, country-regionGermany) will be a unique facility, where heavy ions with energies up to about 45 A GeV can be used for radiation biology experiments. The study of these very high charge and energy (HZE) particles is not only interesting for understanding the mechanisms of radiation action in living system, but also for radiation protection purposes. For space radiobiology, it is generally acknowledged that accelerator-based experiments are preferable to expensive and poorly reproducible flight tests, which are also presently unable to simulate the space radiation field beyond Earth's geomagnetic field. For these very reason, NASA has started the Space Radiation Health Program, building the 34 M NASA Space Radiation Laboratory (NSRL) at the Brookhaven National Laboratory (NY), and funding several research groups for studying biological effects of heavy ions with mass up to 56 (iron) and energy up to metricconverterProductID1 A1 A GeV. FAIR offers a number of unique opportunities in this frame. First, the beamtime available at NSRL is not sufficient to accommodate many non-US research groups, while the research needs are becoming urgent: uncertainty should be reduced to ±50% and effective countermeasures (physical and medical) developed by 2025 if a mission to Mars has to be performed within the first half of the XXI century. FAIR can be used to test a higher energy range (1- metricconverterProductID35 A35 A GeV), which has a low flux in space but is particularly penetrating and consequently impossible to shield. Finally, the raster scanning system used at GSI offers unique opportunities for biological experiments requiring precise exposures of parts of tissue or animal targets. The group of Biophysics at GSI has along experience in the field of space radiation protection, which naturally stems from heavy

  20. High-field 1H NMR microscopy for fundamental biophysical research

    International Nuclear Information System (INIS)

    Haddad, D.


    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

  8. Enhancing Communication in an Egyptian Research Centre

    International Nuclear Information System (INIS)

    Morsy, S.W.


    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.

    International Nuclear Information System (INIS)

    Tanaka, Masaru; Aoyama, Isao; Ishizaka, Kaoru; Ohata, Yuki; Fukuike, Iori; Miyagawa, Hiroshi; Ishimori, Yuu


    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.

  13. RESEARCH: Influence of Social, Biophysical, and Managerial Conditions on Tourism Experiences Within the Great Barrier Reef World Heritage Area. (United States)

    Shafer; Inglis


    / 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.

  15. Biophysical radiosensitization

    International Nuclear Information System (INIS)

    Vladescu, C.; Apetroae, M.


    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).

  1. Biophysics of DNA

    CERN Document Server

    Vologodskii, Alexander


    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.

Bandeirantes, 3900, 14040-901, Ribeirao Preto, SP (Brazil)


    The majority of the biophysical models of olfaction have been focused on the electrical properties of the system, which is justified by the relative facility of recording the electrical activity of the olfactory cells. However, depending on the level of detail utilized, a biophysical model can explore molecular, cellular and network phenomena. This review presents the state of the art of the biophysical approach to understanding olfaction. The reader is introduced to the principal problems involving the study of olfaction and guided gradually to comprehend why it is important to develop biophysical models to investigate olfaction. A large number of representative biophysical efforts in olfaction, their main contributions, the trends for the next generations of biophysical models and the improvements that may be explored by future biophysicists of olfaction have been reviewed.

  8. Travelling Methods: Tracing the Globalization of Qualitative Communication Research

    Directory of Open Access Journals (Sweden)

    Bryan C. Taylor


    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.

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

    Directory of Open Access Journals (Sweden)

    Rasmus Kleis Nielsen


    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.

  16. Biophysics An Introduction

    CERN Document Server

    Glaser, Roland


    Biophysics is the science of physical principles underlying all processes of life, including the dynamics and kinetics of biological systems. This fully revised 2nd English edition is an introductory text that spans all steps of biological organization, from the molecular, to the organism level, as well as influences of environmental factors. In response to the enormous progress recently made, especially in theoretical and molecular biophysics, the author has updated the text, integrating new results and developments concerning protein folding and dynamics, molecular aspects of membrane assembly and transport, noise-enhanced processes, and photo-biophysics. The advances made in theoretical biology in the last decade call for a fully new conception of the corresponding sections. Thus, the book provides the background needed for fundamental training in biophysics and, in addition, offers a great deal of advanced biophysical knowledge.

  9. Creating communicative spaces in an action research study. (United States)

    Bevan, Ann L


    To argue that creating communicative spaces in an action research study gave voice to young mothers who may otherwise have remained voiceless. Underpinning the concept of the communicative space in action research is the critical social theory of Jürgen Habermas, in particular, his theory of communicative action and the ideal speech situation. The author argues that in collaborative research, the successful creation of a communicative space is vital in enabling equitable and discursive speech to take place. This is a methodological paper. This approach provided a discursive space to participants who ordinarily may not have interacted, and led to the sharing of different perceptions and understandings that may not otherwise have been possible. This research pointed to the possibility of the ideal speech situation, and the value of opening up a communicative space for researchers and participants. Action research for professionals is a sometimes messy and time-consuming process. However, it is a rewarding approach that uncovers layers of interpretations and understanding that have meaning for the participants involved. The creation of communicative spaces has the potential to enrich nursing research because of its participatory nature, making it more likely that solutions reached will have meaning to people.

  17. Brazilian science communication research: national and international contributions. (United States)

    Barata, Germana; Caldas, Graça; Gascoigne, Toss


    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.

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

  20. Research on key technology of space laser communication network (United States)

    Chang, Chengwu; Huang, Huiming; Liu, Hongyang; Gao, Shenghua; Cheng, Liyu


    Since the 21st century, Spatial laser communication has made a breakthrough development. Europe, the United States, Japan and other space powers have carried out the test of spatial laser communication technology on-orbit, and put forward a series of plans. In 2011, China made the first technology demonstration of satellite-ground laser communication carried by HY-2 satellite. Nowadays, in order to improve the transmission rate of spatial network, the topic of spatial laser communication network is becoming a research hotspot at home and abroad. This thesis, from the basic problem of spatial laser communication network to solve, analyzes the main difference between spatial network and ground network, which draws forth the key technology of spatial laser communication backbone network, and systematically introduces our research on aggregation, addressing, architecture of spatial network. From the perspective of technology development status and trends, the thesis proposes the development route of spatial laser communication network in stages. So as to provide reference about the development of spatial laser communication network in China.

  5. Communication Capacity Research in the Majority World: Supporting the human right to communication specialist services. (United States)

    Hopf, Suzanne C


    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.

  6. Science communication in the field of fundamental biomedical research (editorial). (United States)

    Illingworth, Sam; Prokop, Andreas


    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.

  7. Shared Communications: Volume 2. In-Depth Systems Research

    Energy Technology Data Exchange (ETDEWEB)

    Truett, LF


    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.

  8. The role of opinion research in communications programmes

    International Nuclear Information System (INIS)

    Curtin, Tom


    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

  14. An ecological framework for cancer communication: implications for research. (United States)

    Patrick, Kevin; Intille, Stephen S; Zabinski, Marion F


    The field of cancer communication has undergone a major revolution as a result of the Internet. As recently as the early 1990s, face-to-face, print, and the telephone were the dominant methods of communication between health professionals and individuals in support of the prevention and treatment of cancer. Computer-supported interactive media existed, but this usually required sophisticated computer and video platforms that limited availability. The introduction of point-and-click interfaces for the Internet dramatically improved the ability of non-expert computer users to obtain and publish information electronically on the Web. Demand for Web access has driven computer sales for the home setting and improved the availability, capability, and affordability of desktop computers. New advances in information and computing technologies will lead to similarly dramatic changes in the affordability and accessibility of computers. Computers will move from the desktop into the environment and onto the body. Computers are becoming smaller, faster, more sophisticated, more responsive, less expensive, and--essentially--ubiquitous. Computers are evolving into much more than desktop communication devices. New computers include sensing, monitoring, geospatial tracking, just-in-time knowledge presentation, and a host of other information processes. The challenge for cancer communication researchers is to acknowledge the expanded capability of the Web and to move beyond the approaches to health promotion, behavior change, and communication that emerged during an era when language- and image-based interpersonal and mass communication strategies predominated. Ecological theory has been advanced since the early 1900s to explain the highly complex relationships among individuals, society, organizations, the built and natural environments, and personal and population health and well-being. This paper provides background on ecological theory, advances an Ecological Model of Internet

    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

  19. Everyday couples' communication research: Overcoming methodological barriers with technology. (United States)

    Reblin, Maija; Heyman, Richard E; Ellington, Lee; Baucom, Brian R W; Georgiou, Panayiotis G; Vadaparampil, Susan T


    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.

  20. Content Analysis as a Foundation for Programmatic Research in Communication. (United States)

    Slater, Michael D


    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.

  1. Defining moments in risk communication research: 1996-2005. (United States)

    McComas, Katherine A


    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.

  2. Cutting through the noise: an evaluative framework for research communication (United States)

    Strickert, G. E.; Bradford, L. E.; Shantz, S.; Steelman, T.; Orozs, C.; Rose, I.


    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.

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

    Directory of Open Access Journals (Sweden)

    Francesco La Barbera


    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.

  15. Beyond communication - research as communicating: making user and audience studies matter - paper 2

    Directory of Open Access Journals (Sweden)

    Brenda Dervin


    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.

  16. Biophysical constraints to sustainable agricultural intensification in West African drylands: an example of the WASCAL Research Action Plan (WRAP 2.0) Flagship Strategy (United States)

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


    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

  17. Glacier Research Digital Science Communication Evolution 1996-2014 (United States)

    Pelto, M. S.


    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.

  18. Communicating in context: a priority for gene therapy researchers. (United States)

    Robillard, Julie M


    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.

    "Theoretical Molecular Biophysics" is an advanced study book for students, shortly before or after completing undergraduate studies, in physics, chemistry or biology. It provides the tools for an understanding of elementary processes in biology, such as photosynthesis on a molecular level. A basic knowledge in mechanics, electrostatics, quantum theory and statistical physics is desirable. The reader will be exposed to basic concepts in modern biophysics such as entropic forces, phase separation, potentials of mean force, proton and electron transfer, heterogeneous reactions coherent and incoherent energy transfer as well as molecular motors. Basic concepts such as phase transitions of biopolymers, electrostatics, protonation equilibria, ion transport, radiationless transitions as well as energy- and electron transfer are discussed within the frame of simple models.

  2. People-Centered Language Recommendations for Sleep Research Communication. (United States)

    Fuoco, Rebecca E


    The growing embrace of patient-centered outcomes research (PCOR) in sleep medicine is a significant step forward for the field. In engaging and incorporating the unique perspectives of people with sleep disorders, PCOR enhances the relevance of findings and facilitates the uptake of research into practice. While centering research design around what matters most to people with sleep disorders is critical, research communication must be similarly people-centered. One approach is using "people-centered language" in both professional and public communications. People-centered language is rooted in sociolinguistic research demonstrating that language both reflects and shapes attitudes. People-centered language puts people first, is precise and neutral, and respects autonomy. By adhering to the language guidelines described in this article, sleep researchers will better serve the field's most important stakeholders. © Sleep Research Society 2017.

  4. Research on cognitive, social and cultural processes of written communication. (United States)

    Arroyo González, Rosario; Salvador Mata, Francisco


    This article compiles the investigations carried out by a Research Group of the University of Granada, Spain. Its different projects on writing's cognitive social and cultural processes have been supported by the Spanish Government. This line of research joined together linguistic, psychological, social and cultural contributions to the development of writing from the 1970s. Currently, this line of research develops in collaboration with other European Universities: (a) Interuniversity Centre for Research On Cognitive Processing in Natural and Artificial Systems (ECONA), "La Sapienza" University of Rome (Italy); (b) Anadolu University, (Eskisehir, Turkey); (c) Coimbra University (Portugal); (d) University of Zaragoza (Spain); (e) the Institute of Education of the University of London (United Kingdom). The aforementioned collaboration is materializing into projects like the International Master on Multilingual Writing: Cognitive, Intercultural and Technological Processes of Written Communication ( ) and the International Congress: Writing in the twenty-first Century: Cognition, Multilinguisim and Technologies, held in Granada ( ). This research line is focussed on the development of strategies in writing development, basic to train twenty-first century societies' citizens. In these societies, participation in production media, social exchange and the development of multilingual written communication skills through new computer technologies spread multicultural values. In order to fulfil the social exigencies, it is needed to have the collaboration of research groups for designing and applying international research projects.

  5. Optimizing Communications Between Arctic Residents and IPY Scientific Researchers (United States)

    Stapleton, M.; Carpenter, L.


    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

    Carey M. Noland


    Full Text Available When conducting research on sensitive topics, it is challenging to use new methods of data collection given the apprehensions of Institutional Review Boards (IRBs. This is especially worrying because sensitive topics of research often require novel approaches. In this article a brief personal history of navigating the IRB process for conducting sex communication research is presented, along with data from a survey that tested the assumptions long held by many IRBs. Results support some of the assumptions IRBs hold about sex communication research, but do not support some other assumptions.

  8. Research integrity in communication sciences and disorders: preface. (United States)

    Moss, Sharon E


    A joint program on Research on Research Integrity sponsored by the National Institute of Neurological Disorders and Stroke and the Office of Research Integrity encouraged the examination of practices and policies promoting the responsible conduct of research (RCR). The authors' grant--Research Integrity in ASHA: Education and Publication--enabled American Speech-Language-Hearing Association's (ASHA) Research Integrity Grant Group to (a) identify patterns of teaching and learning in Communication Sciences and Disorders graduate programs about specific topics of research integrity on the conduct of science, (b) examine perceptions about concepts of research integrity as they apply to scientific journals within the discipline, and (c) evaluate policies and practices established by ASHA to protect the integrity of published scientific work. The authors reviewed historical and contemporary literature, conducted surveys, and analyzed ASHA policies. This supplement of the Journal of Speech, Language, and Hearing Research has been written with the aim of informing and inspiring scientists, students, research institutions, and professional societies to practice responsible research in the 21st century and beyond.

  11. The Dark Snow Project: a hybrid research communication program (United States)

    Box, J. E.; Sinclair, P.


    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.

  13. One exhibition, many goals. Combining scientific research and risk communication (United States)

    Charrière, Marie; Bogaard, Thom; Junier, Sandra; Malet, Jean-Philippe; Mostert, Erik


    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

  14. Enhancing Environmental Communication and Products Through Qualitative Research (United States)

    DeLorme, D.; Hagen, S. C.


    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

  15. A Metasynthesis of Patient-Provider Communication in Hospital for Patients with Severe Communication Disabilities: Informing New Translational Research (United States)

    Balandin, Susan


    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. PMID:25229213

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

    Directory of Open Access Journals (Sweden)

    Hahn Heidi Ann


    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.

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

    Directory of Open Access Journals (Sweden)

    S. M. Forkosh


    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.

  19. Theoretical molecular biophysics

    CERN Document Server

    Scherer, Philipp O J


    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...

  20. Biophysics of radiation action

    International Nuclear Information System (INIS)

    Dertinger, H.


    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

  1. Biophysics and cancer

    CERN Document Server

    Nicolini, Claudio


    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...

  2. Research Collaboration in a Communication Rights Campaign: Lessons Learned. (United States)

    Ryan, Charlotte


    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.

  3. A Research Agenda for Communication Between Health Care Professionals and Patients Living With Serious Illness. (United States)

    Tulsky, James A; Beach, Mary Catherine; Butow, Phyllis N; Hickman, Susan E; Mack, Jennifer W; Morrison, R Sean; Street, Richard L; Sudore, Rebecca L; White, Douglas B; Pollak, Kathryn I


    Poor communication by health care professionals contributes to physical and psychological suffering in patients living with serious illness. Patients may not fully understand their illness, prognosis, and treatment options or may not receive medical care consistent with their goals. Despite considerable research exploring the role of communication in this setting, many questions remain, and a clear agenda for communication research is lacking. Through a consensus conference and subsequent activities, we reviewed the state of the science, identified key evidence gaps in understanding the impact of communication on patient outcomes, and created an agenda for future research. We considered 7 broad topics: shared decision making, advance care planning, communication training, measuring communication, communication about prognosis, emotion and serious illness communication, and cultural issues. We identified 5 areas in which further research could substantially move the field forward and help enhance patient care: measurement and methodology, including how to determine communication quality; mechanisms of communication, such as identifying the specific clinician behaviors that patients experience as both honest and compassionate, or the role of bias in the clinical encounter; alternative approaches to advance care planning that focus on the quality of serious illness communication and not simply completion of forms; teaching and disseminating communication skills; and approaches, such as economic incentives and other clinician motivators, to change communication behavior. Our findings highlight the urgent need to improve quality of communication between health care professionals and patients living with serious illness through a broad range of research that covers communication skills, tools, patient education, and models of care.

  4. Graphical user interfaces for teaching and research in optical communications (United States)

    Almeida, Telmo; Nogueira, Rogerio; André, Paulo


    This paper highlights the use of graphical user interfaces (GUIs) developed with the guide tool from Matlab® for university level optical communications courses and research activities. Graphical user interfaces programmed with Matlab® would not only improve the learning experience, making models easier to understand, but also could be tweaked and improved by students themselves. As Matlab® is already taught in many universities, this would ease the process. An example of a model for a stationary EDFA is given to demonstrate the ease of use and understanding of the role of all the different parameters of the model, so students can get a real interactive experience. Another considered potential application is in research. With GUIs, researchers can make real-time parameter optimization, quick assessments and calculations, or simply showcase their work to broader audiences who may not be so familiar with the topic. A practical example of a research application is given for a parameter optimization of a model for non-linear phenomena in uncompensated long-haul transmission links is given. Besides all the emphasis given to practical applications and potential situations for its use, the paper also covers the basic notions of the critical steps in making a successful Matlab® GUI. Ease of use, visual appearance and computation time are the key features of a successfully implemented GUI.

    Full Text Available In recent years, with the continuous improvement of English teaching way, the interaction and communication way in English teaching has become an important means to improve English teaching. This paper illustrates the benefits of interaction and communication in English teaching, and introduces three interaction and communication ways in English teaching - unilateral communication between teachers and students, multi-directional communication between teachers and students, and multi-level communication between teachers and students, and carries out experimental teaching based on these three ways. This paper uses the factor analysis to analyze the student performance in listening, speaking, reading and writing, and determines the proportion of performance in these four aspects according to the analysis results. This paper evaluates the effect of role of three interaction and communication ways in English teaching according to the fuzzy comprehensive evaluation. The results show that the unilateral communication between teachers and students is slightly superior.

    Scholz, M.; Elsaesser, T.

    One major rationale for the application of ion beams in tumor therapy is their increased relative biological effectiveness RBE in the Bragg peak region For dose prescription the increased effectiveness has to be taken into account in treatment planning Hence the complex dependencies of RBE on the dose level biological endpoint position in the field etc require biophysical models which have to fulfill two important criteria simplicity and quantitative precision Simplicity means that the number of free parameters should be kept at a minimum Due to the lack of precise quantitative data at least at present this requirement is incompatible with approaches aiming at the molecular modeling of the whole chain of production processing and repair of biological damages Quantitative precision is required since steep gradients in the dose response curves are observed for most tumor and normal tissues thus even small uncertainties in the estimation of the biologically effective dose can transform into large uncertainties in the clinical outcome The paper will give a general introduction into the field followed by a brief description of a specific model the so called Local Effect Model LEM This model has been successfully applied within treatment planning in the GSI pilot project for carbon ion tumor therapy over almost 10 years now The model is based on the knowledge of charged particle track structure in combination with the response of the biological objects to conventional photon radiation The model will be critically discussed with respect to other

  10. Biophysics of protein evolution and evolutionary protein biophysics (United States)

    Sikosek, Tobias; Chan, Hue Sun


    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

  16. SUstaiNability: a science communication website on environmental research (United States)

    Gravina, Teresita; Rutigliano, Flora Angela


    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 ( 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. Demographic and geographic

  17. An introduction to environmental biophysics

    CERN Document Server

    Campbell, Gaylon S


    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...

  18. Nutrition communication styles of family doctors: results of quantitative research. (United States)

    van Dillen, S M E; Hiddink, G J; Koelen, M A; van Woerkum, C M J


    To assess the nutrition communication styles of Dutch family doctors and in particular to assess its psychosocial and sociodemographic correlates. A cross-sectional study in which a representative sample of 600 Dutch family doctors completed a questionnaire. The survey was conducted in October and November 2004 in the Netherlands. A total of 267 family doctors completed the questionnaire (response rate 45%). Principal component factor analyses with varimax rotation were performed to construct factors. Cronbach's alpha was used as an index of reliability. Our hypothetical model for nutrition communication style was tested using multiple regression analysis, combining the forward and backward procedures under the condition of the same results. Many family doctors felt at ease with a motivational nutrition communication style. The main predictor for motivational nutrition communication style was task perception of prevention (26%). Some individual and environmental correlates had an additional influence (explained variance 49%). Other styles showed explained variances up to 57%. The motivational style was the best predictor for actual nutrition communication behaviour (35%), while the confrontational style was the best predictor for actual nutrition communication behaviour towards overweight (34%). In contemporary busy practice, family doctors seem to rely on their predominant nutrition communication style to deal with standard situations efficiently: for the majority, this proved to be the motivational nutrition communication style. Moreover, family doctors used a combination of styles. This study suggests that family doctors behave like chameleons, by adapting their style to the specific circumstances, like context, time and patient. If family doctors communicate about nutrition in general, they select any of the five nutrition communication styles. If they communicate about overweight, they pick either the confrontational or motivational style.

  19. Communication masking in marine mammals: A review and research strategy. (United States)

    Erbe, Christine; Reichmuth, Colleen; Cunningham, Kane; Lucke, Klaus; Dooling, Robert


    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.

    Energy Technology Data Exchange (ETDEWEB)

    Haddad, D.


    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.

  3. Research of a portable atmospheric laser communication system (United States)

    Zeng, Wen-feng; Li, Dong; Li, Shen-peng; Tan, Wei; Yi, Zhigang


    A kind of portable atmosphere laser communication system based on fiber technology is designed by using Ethernet transceiver terminal and video-audio transceiver terminal with diode laser module and PIN diode, while a flexible connection is built between the terminal and the optical antenna connected by laser fiber. The application of EDFA technology, which realizes the amplification of the power of the 1550nm laser diode module, brings forth a more stable structure and easier deployment and testing in wild environment, and the communication distance can reach 2 kilometers with a transmission bandwidth of 100 MBit/s. Prototype experiments prove the good communication performance of this system.

  4. Visualization and Interaction in Research, Teaching, and Scientific Communication (United States)

    Ammon, C. J.


    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.

  6. The ethics of good communication in a complex research partnership. (United States)

    Sodeke, Stephen; Turner, Timothy; Tarver, Will


    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.

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

    Directory of Open Access Journals (Sweden)

    Nataša Simeunović Bajić


    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.

  10. The biophysics of neuronal growth

    International Nuclear Information System (INIS)

    Franze, Kristian; Guck, Jochen


    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.

  11. Research on formation of microsatellite communication with genetic algorithm. (United States)

    Wu, Guoqiang; Bai, Yuguang; Sun, Zhaowei


    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.

  14. Introduction: Researching online worlds: challenging media and communication studies

    Directory of Open Access Journals (Sweden)

    Kjetil Sandvik


    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.

  17. Ethics of clear health communication: applying the CLEAN Look approach to communicate biobanking information for cancer research. (United States)

    Koskan, Alexis; Arevalo, Mariana; Gwede, Clement K; Quinn, Gwendolyn P; Noel-Thomas, Shalewa A; Luque, John S; Wells, Kristen J; Meade, Cathy D


    Cancer innovations, such as biobanking technologies, are continuously evolving to improve our understanding and knowledge about cancer prevention and treatment modalities. However, the public receives little communication about biobanking and is often unaware about this innovation until asked to donate biospecimens. It is the researchers' ethical duty to provide clear communications about biobanking and biospecimen research. Such information allows the public to understand biobanking processes and facilitates informed decision making about biospecimen donation. The aims of this paper are 1) to examine the importance of clear communication as an ethical imperative when conveying information about cancer innovations and 2) to illustrate the use of an organizing framework, the CLEAN ( C ulture, L iteracy, E ducation, A ssessment, and N etworking) Look approach for creating educational priming materials about the topic of biobanking.

  18. Crush-2: Communicating research through a science-art collaboration (United States)

    Mair, K.; Barrett, N.; Schubnel, A. J.; Abe, S.


    Historically, the Earth's environment and dynamics have influenced and inspired the arts. Art in turn is a powerful vehicle for expression of the natural world. It lends itself to public presentation in many forms and appeals to a diverse audience. Science-art collaborations provide a unique opportunity to connect with the public by taking science out of the classroom and into museums, galleries and public spaces. Here we investigate the use of contemporary digital sound-art in communicating geoscience research to the general public through the installation Crush-2. Crush-2, is an interactive sound-art installation exploring the microscopic forces released during the crushing of rock. Such processes have a strong influence on the sliding behaviour and hence earthquake potential of active faults. This work is a collaboration between sound artist and composer Natasha Barrett (Oslo) and geoscientists Karen Mair (University of Oslo), Alexandre Schubnel (Ecole Normale Superieure, Paris) and Steffen Abe (RWTH Aachen). Using a sonification technique, Barrett has assigned sound recorded from rocks, of different pitches, timbres and durations, to individual fracturing events produced in our 3D fault fragmentation models and laboratory rock breaking experiments. In addition, ultrasonic acoustic emissions recorded directly in the laboratory are made audible for our hearing and feature in the work. The installation space comprises a loudspeaker array and sensor enabled helmet with wireless headphones. By wearing the helmet, moving and listening, the audience explores an artistic interpretation of the scientific data in physical space. On entering the space, one is immediately immersed in a 3D cacophony of sound. Sustained or intermittent pings, burrs, plops and tingles jostle for position in our heads whilst high pitched delicate cascades juxtapose with deep thunder like rumbles. Depending on the user's precise path through the soundscape, the experience changes accordingly

    D'Addezio, Giuliana; Rubbia, Giuliana; Musacchio, Gemma; Lanza, Tiziana


    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 (, 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

  13. To what extent can people with communication difficulties contribute to health research? (United States)

    Palmer, Rebecca; Paterson, Gail


    To present an approach to involving people with communication disorders in research. Patient and public involvement (PPI) is promoted at all stages of research, with everyone having a right to be involved. However, the high level of communication skills often required precludes the involvement of people with communication disorders. As people from several healthcare groups have communication difficulties, it is important to establish approaches that can help to involve them. A study involving people with communication difficulties using computerised aphasia treatment. The paper describes techniques used to help an advisory group comprising people with aphasia and their carers to collaborate. Reflections on participating in a research group were elicited through videoed interviews. A thematic analysis of the video transcripts identified issues important to the group's members. The approach to patient and public involvement in research enabled collaboration with people with aphasia at all stages of research, including contributing to recruitment, refinement of protocols, new research methods and dissemination of project outcomes. Allowing time for careful preparation of group meetings, facilitation techniques and activities is crucial to achieve this level of involvement. The group experienced increased confidence in communicating, stimulation and feelings of empowerment and being able to influence the future treatment of people with aphasia. People with communication difficulties need not be excluded from PPI activities designed to inform clinical practice or health research. Inclusion of this group can be made possible by using creative methods of exchanging ideas, reducing reliance on rapid, complex spoken interaction.

  15. Understanding Spanish-Language Response in a National Health Communication Survey: Implications for Health Communication Research. (United States)

    Ramírez, A Susana; Willis, Gordon; Rutten, Lila Finney


    Spanish-speaking Latinos account for 13% of the U.S. population yet are chronically under-represented in national surveys; additionally, the response quality suffers from low literacy rates and translation challenges. These are the same issues that health communicators face when understanding how best to communicate important health information to Latinos. The Health Information National Trends Survey (HINTS) offers a unique opportunity to understand the health communication landscape and information needs of the U.S. We describe the challenges in recruiting Spanish-speaking HINTS respondents and strategies used to improve rates and quality of responses among Spanish-speaking Latinos. Cognitive interviewing techniques helped to better understand how Spanish-speaking Latinos were interpreting the survey questions, and the extent to which these interpretations matched English-speaking respondents' interpretations. Some Spanish-speaking respondents had difficulty with the questions because of a lack of access to health care. Additionally, Spanish-speaking respondents had a particularly hard time answering questions that were presented in a grid format. We describe the cognitive interview process, and consider the impact of format changes on Spanish-speaking people's responses and response quality. We discuss challenges that remain in understanding health information needs of non-English-speakers.

  19. Communicating Risks and Benefits in Informed Consent for Research: A Qualitative Study. (United States)

    Nusbaum, Lika; Douglas, Brenda; Damus, Karla; Paasche-Orlow, Michael; Estrella-Luna, Neenah


    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.

  3. Radiobiology, biochemistry and radiation biophysics at CYLAB

    International Nuclear Information System (INIS)

    Ftacnikova, S.


    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

  7. Opportunities and Challenges in Using Research to Facilitate Climate Communication Collaborations (United States)

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


    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.

  9. Communicating Geographical Risks in Crisis Management: The Need for Research. (United States)

    French, Simon; Argyris, Nikolaos; Haywood, Stephanie M; Hort, Matthew C; Smith, Jim Q


    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.

  11. Current and Future AAC Research Considerations for Adults with Acquired Cognitive and Communication Impairments (United States)

    Fried-Oken, Melanie; Beukelman, David R.; Hux, Karen


    Adults with acquired language impairments secondary to stroke, traumatic brain injury, and neurodegenerative diseases are candidates for communication supports outside of the traditional restoration-based approaches to intervention. Recent research proves repeatedly that augmentative and alternative communication (AAC) provides a means for participation, engagement, conversation, and message transfer when individuals can no longer expect full return of pre-morbid communication skills and that inclusion of communication supports should begin early. We discuss current research and future directions for integrated systems of technical supports that include low-technology, high tech, and partner-dependent strategies for adults with severe and chronic aphasia, cognitive-communication problems resulting from traumatic brain injuries, and primary progressive aphasia.

  13. What conceptions of science communication are espoused by science research funding bodies? (United States)

    Palmer, Sarah E; Schibeci, Renato A


    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.

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

    Directory of Open Access Journals (Sweden)

    Shigehiro Hashimoto


    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.

  18. Exploring risk communication - results of a research project focussed on effectiveness evaluation (United States)

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


    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

    International Nuclear Information System (INIS)

    Wight, Evelyn; Gardner, Gene; Harvey, Tony


    As a reflection of its growing culture of openness, and in response to the public's need for accurate information about its activities, the U.S. Department of Energy (DOE) Office of the Assistant Secretary for Environmental Restoration and Waste Management (EM) has increased the amount of information available to the public through communication tools such as brochures, fact sheets, and a travelling exhibit with an interactive computer display. Our involvement with this effort has been to design, develop, and critique booklets, brochures, fact sheets and other communication tools for EM. This paper presents an evaluation of the effectiveness of two communication tools we developed: the EM Booklet and the EM Fact Sheets. We measured effectiveness using non-parametric testing. This paper describes DOE's culture change, EM's communication tools and their context within DOE'S new open culture, our research, test methods and results, the significance of our research, and our plans for future research.

  1. The evolving concept of "patient-centeredness" in patient-physician communication research. (United States)

    Ishikawa, Hirono; Hashimoto, Hideki; Kiuchi, Takahiro


    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.

    Vít Chlebovský


    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 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.

    Highlights: • The 2000–2634 aa region of HUWE1 mediates the interaction with BRCA1 degron. • HUWE1 promotes the degradation of BRCA1 through the ubiquitin–proteasome pathway. • HUWE1 expression is inversely correlated with BRCA1 in breast cancer cells. • RNAi inhibition of HUWE1 confers increased resistance of MCF-10F cells to IR and MMC. - Abstract: The cellular BRCA1 protein level is essential for its tumor suppression activity and is tightly regulated through multiple mechanisms including ubiquitn–proteasome system. E3 ligases are involved to promote BRCA1 for ubiquitination and degradation. Here, we identified HUWE1/Mule/ARF-BP1 as a novel BRCA1-interacting protein involved in the control of BRCA1 protein level. HUWE1binds BRCA1 through its N-terminus degron domain. Depletion of HUWE1 by siRNA-mediated interference significantly increases BRCA1 protein levels and prolongs the half-life of BRCA1. Moreover, exogenous expression of HUWE1 promotes BRCA1 degradation through the ubiquitin–proteasome pathway, which could explain an inverse correlation between HUWE1 and BRCA1 levels in MCF10F, MCF7 and MDA-MB-231 breast cancer cells. Consistent with a functional role for HUWE1 in regulating BRCA1-mediated cellular response to DNA damage, depletion of HUWE1 by siRNA confers increased resistance to ionizing radiation and mitomycin. These data indicate that HUWE1 is a critical negative regulator of BRCA1 and suggest a new molecular mechanism for breast cancer pathogenesis.

  6. Effective communication tools to engage Torres Strait Islanders in scientific research (United States)

    Jones, A.; Barnett, B.; Williams, A. J.; Grayson, J.; Busilacchi, S.; Duckworth, A.; Evans-Illidge, E.; Begg, G. A.; Murchie, C. D.


    Often, research activities in Torres Strait have not delivered full benefit to Torres Strait Islanders due to a lack of consultation, ineffectual communication of research information and lack of empathy for the needs of Islander communities. As for other stakeholder groups, integration of Islanders into the research process through practical involvement in research may overcome these problems. Three case studies from research projects conducted in Torres Strait are discussed to highlight a variety of communication and engagement activities carried out by non-Indigenous researchers. How these communication and extension activities facilitate collaboration between Torres Strait Islander and non-Indigenous researchers provides insight in the importance of these activities to the relative success of research projects. The benefits for Islanders in collaborating with researchers may be: improved understanding of the research and how it contributes to natural resource management; a sense of control in future management decisions; a greater likelihood of successful self-regulatory management systems; enhanced skills; and increased employment opportunities. The potential benefits for researchers are enhanced support for research projects resulting in increased access to data and logistic support that may ultimately impact the successful completion of projects. Such an approach will require researchers to take time to develop relationships with Torres Strait Islanders, effectively involve Islanders in research on an equitable basis and be flexible. This will ultimately require funding organisations to recognise the importance of such activities in research proposals and provide support through sufficient funding to enable these activities to be carried out.

  7. Designing AAC Research and Intervention to Improve Outcomes for Individuals with Complex Communication Needs. (United States)

    Light, Janice; Mcnaughton, David


    There is a rapidly growing body of research that demonstrates the positive effects of augmentative and alternative communication (AAC) intervention on the communication of children and adults with complex communication needs. Despite the positive impact of many AAC interventions, however, many individuals with complex communication needs continue to experience serious challenges participating in educational, vocational, healthcare, and community environments. In this paper, we apply the framework proposed by the International Classification of Functioning, Disability and Health (ICF) to illustrate the need to re-think AAC intervention to improve outcomes for individuals with complex communication needs, and to foster a new generation of intervention research that will provide a solid foundation for improved services. Specifically, the paper emphasizes the need to take a more holistic view of communication intervention and highlights the following key principles to guide AAC intervention and research: (a) build on the individual's strengths and focus on the integration of skills to maximize communication, (b) focus on the individual's participation in real-world contexts, (c) address psychosocial factors as well as skills, and (d) attend to extrinsic environmental factors as well as intrinsic factors related to the individual who requires AAC.

  9. Towards Advancing Knowledge Translation of AAC Outcomes Research for Children and Youth with Complex Communication Needs. (United States)

    Ryan, Stephen E; Shepherd, Tracy; Renzoni, Anne Marie; Anderson, Colleen; Barber, Mary; Kingsnorth, Shauna; Ward, Karen


    The production of new knowledge in augmentative and alternative communication (AAC) requires effective processes to leverage the different perspectives of researchers and knowledge users and improve prospects for utilization in clinical settings. This article describes the motivation, planning, process, and outcomes for a novel knowledge translation workshop designed to influence future directions for AAC outcomes research for children with complex communication needs. Invited knowledge users from 20 pediatric AAC clinics and researchers engaged in the collaborative development of research questions using a framework designed for the AAC field. The event yielded recommendations for research and development priorities that extend from the early development of language, communication, and literacy skills in very young children, to novel but unproven strategies that may advance outcomes in transitioning to adulthood.

  11. Biophysical stimulation of bone fracture repair, regeneration and remodelling

    Directory of Open Access Journals (Sweden)

    Chao E. Y.S.


    Full Text Available Biophysical stimulation to enhance bone fracture repair and bone regenerate maturation to restore its structural strength must rely on both the biological and biomechanical principle according to the local tissue environment and the type of mechanical stress to be born by the skeletal joint system. This paper reviews the possible interactions between biophysical stimuli and cellular responses in healing bone fractures and proceeds to speculate the prospects and limitations of different experimental models in evaluating and optimising such non-invasive interventions. It is important to realize that bone fracture repair has several pathways with various combinations of bone formation mechanisms, but there may only be one bone remodeling principle regulated by the hypothesis proposed by Wolff. There are different mechanical and biophysical stimuli that could provide effective augmentation of fracture healing and bone regenerate maturation. The key requirements of establishing these positive interactions are to define the precise cellular response to the stimulation signal in an in vitro environment and to use well-established animal models to quantify and optimise the therapeutic regimen in a time-dependent manner. This can only be achieved through research collaboration among different disciplines using scientific methodologies. In addition, the specific forms of biophysical stimulation and its dose effect and application timing must be carefully determined and validated. Technological advances in achieving focalized stimulus delivery with adjustable signal type and intensity, in the ability to monitor healing callus mechanical property non-invasively, and in the establishment of a robust knowledgebase to develop effective and reliable treatment protocols are the essential pre-requisites to make biophysical stimulation acceptable in the main arena of health care. Finally, it is important to bear in mind that successful fracture repair or bone

    Full Text Available 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.

    Gravina, Teresita; Muselli, Maurizio; Ligrone, Roberto; Rutigliano, Flora Angela


    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 ( 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.

Furthermore we directly observed the time-dependent dimerization of β2AR and Cannabinoid receptor 1 at the single molecule...... level, and revealed the existence of several dimerization interfaces, each with specific kinetics. Finally we investigated how a property of the membrane solubilizing GPCRs affected oligomerization. We observed a dramatic decrease in oligomer stability with increasing geometrical membrane curvature. We...

  16. Biophysical aspects of photodynamic therapy. (United States)

    Juzeniene, Asta; Nielsen, Kristian Pagh; Moan, Johan


    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.

  17. Mapping science communication scholarship in China: Content analysis on breadth, depth and agenda of published research. (United States)

    Xu, Linjia; Huang, Biaowen; Wu, Guosheng


    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.

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

    International Nuclear Information System (INIS)

    Chu, H.


    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

  1. Microwave Tissue Ablation: Biophysics, Technology and Applications (United States)


    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.

  2. Biophysics of NASA radiation quality factors. (United States)

    Cucinotta, Francis A


    NASA has implemented new radiation quality factors (QFs) for projecting cancer risks from space radiation exposures to astronauts. The NASA QFs are based on particle track structure concepts with parameters derived from available radiobiology data, and NASA introduces distinct QFs for solid cancer and leukaemia risk estimates. The NASA model was reviewed by the US National Research Council and approved for use by NASA for risk assessment for International Space Station missions and trade studies of future exploration missions to Mars and other destinations. A key feature of the NASA QFs is to represent the uncertainty in the QF assessments and evaluate the importance of the QF uncertainty to overall uncertainties in cancer risk projections. In this article, the biophysical basis for the probability distribution functions representing QF uncertainties was reviewed, and approaches needed to reduce uncertainties were discussed. © The Author 2015.

  9. Memory and communication support in dementia: research-based strategies for caregivers. (United States)

    Smith, Erin R; Broughton, Megan; Baker, Rosemary; Pachana, Nancy A; Angwin, Anthony J; Humphreys, Michael S; Mitchell, Leander; Byrne, Gerard J; Copland, David A; Gallois, Cindy; Hegney, Desley; Chenery, Helen J


    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.

    C.M.E. McCrindle


    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 %.

  11. Recent Efforts in Communications Research and Technology at the Glenn Research Center in Support of NASA's Mission (United States)

    Miranda, Felix A.


    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.

  12. Communicating Research Through Student Involvement in Phenological Investigations (United States)

    Sparrow, E. B.; Kopplin, M.; Gazal, R. M.; Robin, J. H.; Boger, R. A.


    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

  15. Nanoscale biophysics of the cell

    CERN Document Server

    Ashrafuzzaman, Mohammad


    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.

  17. A History of the Western Institute of Nursing and Its Communicating Nursing Research Conferences. (United States)

    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.

  19. A call for innovative social media research in the field of augmentative and alternative communication. (United States)

    Hemsley, Bronwyn; Balandin, Susan; Palmer, Stuart; Dann, Stephen


    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.

  20. Conducting research in risk communication that is both beneficial for stakeholders and scientists (United States)

    Charrière, Marie; Bogaard, Thom; Junier, Sandra; Malet, Jean-Philippe; Mostert, Erik


    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. Later local technicians and inhabitants contributed to the content of the exhibition and regional stakeholders helped with the funding of the exhibition. Finally, employees of the public library took

  1. Research of remote control for Chinese Antarctica Telescope based on iridium satellite communication (United States)

    Xu, Lingzhe; Yang, Shihai


    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.

  3. Tweet reach: a research protocol for using Twitter to increase information exchange in people with communication disabilities. (United States)

    Hemsley, Bronwyn; Palmer, Stuart; Balandin, Susan


    To (a) outline the background to research evaluating Twitter use by people with severe physical and communication disabilities participating actively in online communication forums for increasing information exchange and (b) illustrate a range of potential methods that might be applied in furthering research on the use of social media by people with developmental and acquired communication disabilities. The literature on communication disabilities, augmentative and alternative communication, and social media research informed the rationale for and design of three studies investigating the use of Twitter by people with communication disabilities. To date, there is little information in the literature about how people with a range of communication disabilities might use Twitter to increase their access to information and help them to feel knowledgeable and in control of their own lives. In this paper, three studies are proposed to investigate the use of Twitter by people with communication disabilities.

  4. The communication of forensic science in the criminal justice system: A review of theory and proposed directions for research. (United States)

    Howes, Loene M


    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.

  5. Intercultural and Cross-Cultural Communication Research: Some Reflections about Culture and Qualitative Methods

    Directory of Open Access Journals (Sweden)

    Maria Assumpta Aneas


    Full Text Available This article attempts to offer a response, from a general perspective, to the question of how culture reveals itself in the application of qualitative research methods in intercultural communication. When we use the term "culture" it is important to bear in mind that culturally attributed social interaction processes are themselves the result of socially constructed processes. They are part of an individual-collective dialectic with multiple potential meanings, which are emergent and in constant reformulation from a wide variety of social and cultural perspectives. Much of the recent research in intercultural communication has been directed towards the study of these systems of culturally related meanings. The literature we review offers perspectives from a variety of disciplines and insights into the role of culture in communication processes. URN: urn:nbn:de:0114-fqs0901519

  7. Building a Data Science capability for USGS water research and communication (United States)

    Appling, A.; Read, E. K.


    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.

  8. Antecedents and Consequences of Therapeutic Communication in Iranian Nursing Students: A Qualitative Research (United States)


    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.

    Kanki, Barbara G.; Hart, Sandra G. (Technical Monitor)


    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

  12. Mapping the Landscape of Qualitative Research on Intercultural Communication. A Hitchhiker's Guide to the Methodological Galaxy

    Directory of Open Access Journals (Sweden)

    Matthias Otten


    Full Text Available An exploration of the interdisciplinary field of intercultural communication reveals both very inspiring thoughts and instruments to analyze culture in human interaction, and a confusing diversity of methods and arguments to deal with. In this article a "conceptual metaphor" (LAKOFF & JOHNSON, 1980 of exploring unknown territories and spaces is proposed for establishing a heuristic frame to maneuver through a rapidly expanding "galaxy" of research on intercultural communication. The aim is to provide a general framework to assess the methodological coherence of empirical studies on intercultural communication, as well as their relative position in the wider field of qualitative social research methodologies. Three dimensions will be discussed: 1 The theoretical question of the underlying cultural concept of a research project, 2 the methodical question of the basic research design and modes of analysis, and 3 the question of generalizations drawn from the empirical findings. These dimensions constitute what we call a methodological galaxy in which current trends and developments of the field of intercultural communication can be located and traced. The suggested framework may serve as a guiding "compass," using a set of "etic" parameters for navigation while respecting the "emic" nature of qualitative approaches.

  3. Historical and Critical Review on Biophysical Economics (United States)

    Adigüzel, Yekbun


    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.

  5. Incorporating modeling and simulations in undergraduate biophysical chemistry course to promote understanding of structure-dynamics-function relationships in proteins. (United States)

    Hati, Sanchita; Bhattacharyya, Sudeep


    A project-based biophysical chemistry laboratory course, which is offered to the biochemistry and molecular biology majors in their senior year, is described. In this course, the classroom study of the structure-function of biomolecules is integrated with the discovery-guided laboratory study of these molecules using computer modeling and simulations. In particular, modern computational tools are employed to elucidate the relationship between structure, dynamics, and function in proteins. Computer-based laboratory protocols that we introduced in three modules allow students to visualize the secondary, super-secondary, and tertiary structures of proteins, analyze non-covalent interactions in protein-ligand complexes, develop three-dimensional structural models (homology model) for new protein sequences and evaluate their structural qualities, and study proteins' intrinsic dynamics to understand their functions. In the fourth module, students are assigned to an authentic research problem, where they apply their laboratory skills (acquired in modules 1-3) to answer conceptual biophysical questions. Through this process, students gain in-depth understanding of protein dynamics-the missing link between structure and function. Additionally, the requirement of term papers sharpens students' writing and communication skills. Finally, these projects result in new findings that are communicated in peer-reviewed journals. © 2016 The International Union of Biochemistry and Molecular Biology.

  6. Non-communicable diseases: mapping research funding organisations, funding mechanisms and research practices in Italy and Germany. (United States)

    Stephani, Victor; Sommariva, Silvia; Spranger, Anne; Ciani, Oriana


    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.

  7. Biophysics, Pathophysiology and Pharmacology of Ion Channel Gating Pores

    Directory of Open Access Journals (Sweden)

    Adrien eMoreau


    Full Text Available Voltage sensor domain (VSDs are a feature of voltage gated ion channel (VGICs and voltage sensitive proteins. They are composed of four transmembrane (TM segments (S1 to S4. Currents leaking through VSDs are called omega or gating pore currents.Gating pores are caused by mutations of the highly conserved positively charged amino acids in the S4 segment that disrupt interactions between the S4 segment and the gating charge transfer center (GCTC. The GCTC separates the intracellular and extracellular water crevices. The disruption of S4–GCTC interactions allows these crevices to communicate and create a fast activating and non-inactivating alternative cation-selective permeation pathway of low conductance, or a gating pore.Gating pore currents have recently been shown to cause periodic paralysis phenotypes. There is also increasing evidence that gating pores are linked to several other familial diseases. For example, gating pores in Nav1.5 and Kv7.2 channels may underlie mixed arrhythmias associated with dilated cardiomyopathy (DCM phenotypes and peripheral nerve hyperexcitability (PNH respectively. There is little evidence for the existence of gating pore blockers. Moreover, it is known that a number of toxins bind to the VSD of a specific domain of Na+ channels. These toxins may thus modulate gating pore currents. This focus on the VSD motif opens up a new area of research centered on developing molecules to treat a number of cell excitability disorders such as epilepsy, cardiac arrhythmias, and pain.The purpose of the present review is to summarize existing knowledge of the pathophysiology, biophysics, and pharmacology of gating pore currents and to serve as a guide for future studies aimed at improving our understanding of gating pores and their pathophysiological roles.

  8. Pilot research project of risk communication on nuclear technology and its utilization. Toward communication and collaboration with community

    International Nuclear Information System (INIS)

    Tsuchiya, Tomoko


    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.

  12. Research of communication quality assessment algorithm according to the standard G3-PLC (United States)

    Chebotayev, Pavel; Klimenko, Aleksey; Myakochin, Yuri; Polyakov, Igor; Shelupanov, Alexander; Urazayev, Damir; Zykov, Dmitriy


    The present paper deals with the quality assessment of PLC channel which is a part of fault-tolerant self-organizing heterogeneous communication system. The PLC implementation allows to reduce exploitation costs when constructing new info-communication networks. PLC is used for transmitting information between various devices in alternating current mains. There exist different approaches to transfer information over power lines. Their differences resulted from the requirements of typical apps which use PLC as a data transmission channel. In the process of research described in this paper, the simulation of a signal in AC mains with regard to different kinds of noise caused by power line loads was performed.

    Despite the quickening momentum of genomic discovery, the communication, behavioral, and social sciences research needed for translating this discovery into public health applications has lagged behind. The National Human Genome Research Institute held a 2-day workshop in October 2008 convening an interdisciplinary group of scientists to recommend forward-looking priorities for translational research. This research agenda would be designed to redress the top three risk factors (tobacco use, poor diet, and physical inactivity) that contribute to the four major chronic diseases (heart disease, type 2 diabetes, lung disease, and many cancers) and account for half of all deaths worldwide. Three priority research areas were identified: (1) improving the public's genetic literacy in order to enhance consumer skills; (2) gauging whether genomic information improves risk communication and adoption of healthier behaviors more than current approaches; and (3) exploring whether genomic discovery in concert with emerging technologies can elucidate new behavioral intervention targets. Important crosscutting themes also were identified, including the need to: (1) anticipate directions of genomic discovery; (2) take an agnostic scientific perspective in framing research questions asking whether genomic discovery adds value to other health promotion efforts; and (3) consider multiple levels of influence and systems that contribute to important public health problems. The priorities and themes offer a framework for a variety of stakeholders, including those who develop priorities for research funding, interdisciplinary teams engaged in genomics research, and policymakers grappling with how to use the products born of genomics research to address public health challenges. 2010.

  14. Communication Research. Bibliometric analysis of the most-cited ISI-indexed Journals

    Directory of Open Access Journals (Sweden)

    Ana Almansa-Martínez


    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.

  15. Research on risk communication after the Fukushima nuclear power plant accident

    International Nuclear Information System (INIS)

    Horiguchi, Itsuko


    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)

  17. [Potential analysis of research on speech therapy-led communication training in aphasia following stroke]. (United States)

    Kempf, Sabrina; Lauer, Norina; Corsten, Sabine; Voigt-Radloff, Sebastian


    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

  18. Advancing Partner Notification Through Electronic Communication Technology: A Review of Acceptability and Utilization Research. (United States)

    Pellowski, Jennifer; Mathews, Catherine; Kalichman, Moira O; Dewing, Sarah; Lurie, Mark N; Kalichman, Seth C


    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.

  19. Research on demodulation technology of atmospheric laser communication system base on CPolSK (United States)

    xin, zhou; Liu, Yan; Liu, Zhi; Liu, Dan; Fang, Han-han; Zheng, Min


    In order to reduce the impacts of atmospheric turbulence and background light etc. factors to atmospheric laser communication system performance, the atmospheric laser communication system using circular polarization modulation technology is adopted and researched. This system uses polarization shift keying modulation (PloSK), which is a new standard digital modulation technique in optical communication field. In this modulation, two rotation states of the circle polarization light (left handed and right handed) representation logic signal ' 0 ' and ' 1 ', are used to information loaded and data transmission. In the receiver, the modulation optical signal is detected with dual differential probe method. Under the OptiSystem system simulation environment, several direct detection system model based on OOK intensity modulation, single rode circular polarization modulation and circular polarization modulation with balanced detection is constructed, and compares and analysis of the various communication system performance. The results show that: at the same parameter conditions, bit error rate of CPolSK system with balanced detection lower about two orders of magnitude than the OOK system and single rode CPolSK system, the eye diagram and the waveform chart are also significantly better than OOK system's. It can be seen, based on circular polarization shift keying (CPolSK) laser communication system with dual differential detection is superior on anti-interference of atmospheric interference, and reducing error rate, and will be easy to implement.

  20. Communication is the key to success in pragmatic clinical trials in Practice-based Research Networks (PBRNs). (United States)

    Bertram, Susan; Graham, Deborah; Kurland, Marge; Pace, Wilson; Madison, Suzanne; Yawn, Barbara P


    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.

    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.

    Abernethy, Amy P; Capell, Warren H; Aziz, Noreen M; Ritchie, Christine; Prince-Paul, Maryjo; Bennett, Rachael E; Kutner, Jean S


    Palliative care has faced moral and ethical challenges when conducting research involving human subjects. There are currently no resources to guide institutional review boards (IRBs) in applying standard ethical principles and terms-in a specific way-to palliative care research. Using as a case study a recently completed multisite palliative care clinical trial, this article provides guidance and recommendations for both IRBs and palliative care investigators to facilitate communication and attain the goal of conducting ethical palliative care research and protecting study participants while advancing the science. Beyond identifying current challenges faced by palliative care researchers and IRBs reviewing palliative care research, this article suggests steps that the palliative care research community can take to establish a scientifically sound, stable, productive, and well-functioning relationship between palliative care investigators and the ethical bodies that oversee their work.

    Harrison, M; Koh, J; Tran, S; Mongkolwat, P; Channin, D S


    To identify practical issues surrounding delivering digital images from picture archiving and communication systems (PACS) for research and teaching purposes. The complexity of Digital Imaging and Communications in Medicine (DICOM) access methods, security, patient confidentiality, PACS database integrity, portability, and scalability are discussed. A software prototype designed to resolve these issues is described. A six-component, three-tier, client server software application program supporting DICOM query/retrieve services was developed in the JAWA language. This software was interfaced to a large GE (Mt Prospect, IL) Medical Systems clinical PACS at Northwestern Memorial Hospital (NMH). Images can be delivered from a clinical PACS for research and teaching purposes. Concerns for security, patient confidentiality, integrity of the PACS database, and management of the transactions can be addressed. The described software is one such solution for achieving this goal.

  6. Antecedents and Consequences of Therapeutic Communication in Iranian Nursing Students: A Qualitative Research

    Directory of Open Access Journals (Sweden)

    Mahbobeh Abdolrahimi


    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.

  7. Open Access to Scholarly Research : An Emerging Success Story in Emancipatory Communication


    Morrison, Heather


    Open access is defined, and explored in the context of enclosure and emancipatory communication. One attempt at enclosure, in the form of heavy lobbying by very wealthy companies in the publishing industry against research funders' open access mandates, has been exposed. A PR message is traced from the recommendations of PR pitbull Eric Dezenhall to a failed anti-OA coalition attempt called PRISM to the White House. In spite of this intense lobbying, open access is succeeding. Resources are ...

    Plumpton, Heather; Dearing Crampton-Flood, E.; Gowan, Evan J.; Dassié, E.P.


    It is not an easy task for paleoscientists to communicate the relevance of their research to policy makers and funders. However, an increase in catastrophic environmental calamities related to climate change (e.g. landslide, droughts, flooding) demands a response both in terms of policy-making and future governmental decisions. Often, climate change in the recent past was linked to major shifts in human behavior, which masks the relative contribution of humans and nature. For example, the 4.2...

  10. Stroke Research Staff's Experiences of Seeking Consent from People with Communication Difficulties: Results of a National Online Survey. (United States)

    Jayes, Mark J; Palmer, Rebecca L


    The process of obtaining informed consent from people with communication difficulties is challenging. An online survey was conducted to explore the experiences of stroke research staff in seeking consent from this population. To identify how stroke research staff seek consent from people with communication difficulties, potential barriers to effective practice, and ways to improve practice. All research staff working for the National Institute for Health Research Stroke Research Network in England were invited to complete an online questionnaire. Data were collected anonymously between March and June 2013. Quantitative data were analyzed using descriptive statistics, and qualitative data were coded using thematic analysis. Seventy-five research staff responded, corresponding to a response rate of 10%. There were 97% who had sought consent from people with communication difficulties and 52% did this regularly; 65% had received training in consenting this population. Most staff were aware of appropriate methods for supporting communication needs, but only 18% regularly used accessible information and 35% regularly used augmentative communication techniques. Lack of specific training and lack of access to ethically approved materials were suggested barriers to using these methods. Respondents indicated that people with impaired communication may be excluded from the consent process because they are not eligible for inclusion in studies or because assent is obtained from third parties. For research staff to work more effectively with this population, study protocols need to be more inclusive of people with communication difficulties, and staff need better access to ethically approved, accessible communication resources and appropriate training.

  11. Beyond the Data: Effective Methods for Communicating the Value of Geoscience Research (United States)

    Lees, J. M.; Parker, M. L.


    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.

    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

  13. Lab-on-a-Chip Platforms for Biophysical Studies of Cancer with Single-Cell Resolution. (United States)

    Shukla, Vasudha C; Kuang, Tai-Rong; Senthilvelan, Abirami; Higuita-Castro, Natalia; Duarte-Sanmiguel, Silvia; Ghadiali, Samir N; Gallego-Perez, Daniel


    Recent cancer research has more strongly emphasized the biophysical aspects of tumor development, progression, and microenvironment. In addition to genetic modifications and mutations in cancer cells, it is now well accepted that the physical properties of cancer cells such as stiffness, electrical impedance, and refractive index vary with tumor progression and can identify a malignant phenotype. Moreover, cancer heterogeneity renders population-based characterization techniques inadequate, as individual cellular features are lost in the average. Hence, platforms for fast and accurate characterization of biophysical properties of cancer cells at the single-cell level are required. Here, we highlight some of the recent advances in the field of cancer biophysics and the development of lab-on-a-chip platforms for single-cell biophysical analyses of cancer cells.

    Cappella, Joseph N


    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.

  17. Considering the role of social dynamics and positional behavior in gestural communication research. (United States)

    Smith, Lindsey W; Delgado, Roberto A


    While the hominin fossil record cannot inform us on either the presence or extent of social and cognitive abilities that may have paved the way for the emergence of language, studying non-vocal communication among our closest living relatives, the African apes, may provide valuable information about how language originated. Although much has been learned from gestural signaling in non-human primates, we have not yet established how and why gestural repertoires vary across species, what factors influence this variation, and how knowledge of these differences can contribute to an understanding of gestural signaling's contribution to language evolution. In this paper, we review arguments surrounding the theory that language evolved from gestural signaling and suggest some important factors to consider when conducting comparative studies of gestural communication among African apes. Specifically, we propose that social dynamics and positional behavior are critical components that shape the frequency and nature of gestural signaling across species and we argue that an understanding of these factors could shed light on how gestural communication may have been the basis of human language. We outline predictions for the influence of these factors on the frequencies and types of gestures used across the African apes and highlight the importance of including these factors in future gestural communication research with primates. © 2013 Wiley Periodicals, Inc.

  18. Talk to the Hand: U.S. Army Biophysical Testing. (United States)

    Santee, William R; Potter, Adam W; Friedl, Karl E


    Many people are unaware of the science underlying the biophysical properties of Soldier clothing and personal protective equipment, yet there is a well-refined biomedical methodology initiated by Army physiologists in World War II. This involves a methodical progression of systematic material testing technologies, computer modeling, and human testing that enables more efficient development and rapid evaluation of new concepts for Soldier health and performance. Sophisticated manikins that sweat and move are a central part of this testing continuum. This report briefly summarizes the evolution and use of one specialized form of the manikin technologies, the thermal hand model, and its use in research on Soldier hand-wear items that sustain dexterity and protect the hand in extreme environments. Thermal manikin testing methodologies were developed to provide an efficient and consistent analytical tool for the rapid evaluation of new clothing concepts. These methods have been upgraded since the original World War II and Korean War eras to include articulation and sweating capabilities, as characterized and illustrated in this article. The earlier "retired" versions of thermal hand models have now been transferred to the National Museum of Health and Science. The biophysical values from manikin testing are critical inputs to the U.S. Army Research Institute of Environmental Medicine mathematical models that provide predictions of soldier comfort, duration of exposure before loss of manual dexterity, and time to significant risk of freezing (skin temperature Army has been on the forefront of the biophysical analysis of clothing including gloves since environmental research was established at the Armored Medical Research Laboratory and Climatic Research Laboratory during World War II.

  20. Leading US nano-scientists’ perceptions about media coverage and the public communication of scientific research findings

    International Nuclear Information System (INIS)

    Corley, Elizabeth A.; Kim, Youngjae; Scheufele, Dietram A.


    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.

  1. Engineered biomaterial and biophysical stimulation as combinatorial strategies to address prosthetic infection by pathogenic bacteria. (United States)

    Boda, Sunil Kumar; Basu, Bikramjit


    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.

  2. Mapping genetic research in non-communicable disease publications in selected Arab countries: first step towards a guided research agenda. (United States)

    Jamaluddine, Zeina; Sibai, Abla Mehio; Othman, Shahd; Yazbek, Soha


    In the Arab world, intervention and policy response to non-communicable diseases (NCD) has been weak despite extensive epidemiological evidence highlighting the alarmingly increased prevalence of chronic diseases. Generating genetic information is one key component to promote efficient disease management strategies. This study undertook a scoping review to generate the profile of the undertaken research on genetics of NCD publications in selected Arab countries. An analysis of the research produced examined the extent, range, nature, topic and methods of published research. The study aimed at identifying the gaps in genetic NCD research to inform policy action for NCD prevention and control. The scoping review was conducted based on the five-stage methodological framework and included countries in Arab region selected to represent various economies and epidemiological transitions. The search identified 555 articles that focus on genetics-NCD research in the selected Arab countries over the duration of this study (January 2000 to December 2013). The most commonly conducted research was descriptive and clinically focused, rather than etiologically focused. Country-specific carrier and risk screening studies were not among the top research designs. The genetic component of certain highly heritable diseases, as well as diabetes, obesity, hypertension, chronic lung dysfunction and metabolic syndrome were all under investigated. This scoping review identified gaps for further research in the context of bioinformatics and genome-wide association studies. Genetic research in the Arab region has to be redirected towards NCDs with the highest morbidity, heritability and health burden within each country. A focused research plan to include community genetics is required for its proper integration in the Arab community.

  3. Narrative communication in cancer prevention and control: a framework to guide research and application. (United States)

    Kreuter, Matthew W; Green, Melanie C; Cappella, Joseph N; Slater, Michael D; Wise, Meg E; Storey, Doug; Clark, Eddie M; O'Keefe, Daniel J; Erwin, Deborah O; Holmes, Kathleen; Hinyard, Leslie J; Houston, Thomas; Woolley, Sabra


    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.

  4. Storylines as an alternative method to communicate river research via a knowledge platform (United States)

    Cortes Arevalo, Juliette; Verbrugge, Laura N. H.; den Haan, Robert Jan; Baart, Fedor; Hulscher, Suzanne J. M. H.; van der Voort, Mascha C.


    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

  5. Risky, aggressive, or emotional driving: addressing the need for consistent communication in research. (United States)

    Dula, Chris S; Geller, E Scott


    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.

  6. Front end evaluation research results. Communications and concept planning: Hatfield Marine Science Center (United States)

    Falk, John H.; Holland, Dana


    An evaluation for the renovation of the existing visitor center at the Hatfield Marine Sciences Center (HMSC) was undertaken, in conjunction with the communications planning phase of the project. The outcome is expected to be the development of a communications plan and selection of concepts for visitors' interpretive experience. In the course of the evaluation, data were collected from 140 visitors to HMSC using both a questionnaire and face to face semi-structured interviews. Major results of the evaluation covered: 1, reasons for attending the HMSC; 2, visitor expectations; 3, visitors's knowledge of general science and of marine life and environments; 4, visitors' level of interest and attitudes toward exhibit themes; 5, issue areas of greatest interest; and 6, research areas of greatest interest.Visitors to t he HMSC had a strong orientation toward seeing and closely interacting with marine life and environments.

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

    Directory of Open Access Journals (Sweden)

    F.W. Dulle


    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.

  9. Building Interdisciplinary Research and Communication Skills in the Agricultural and Climate Sciences (United States)

    Johnson-Maynard, J.; Borrelli, K.; Wolf, K.; Bernacchi, L.; Eigenbrode, S.; Daley Laursen, D.


    Preparing scientists and educators to create and promote practical science-based agricultural approaches to climate change adaptation and mitigation is a main focus of the Regional Approaches to Climate Change (REACCH) project. Social, political and environmental complexities and interactions require that future scientists work across disciplines rather than having isolated knowledge of one specific subject area. Additionally, it is important for graduate students earning M.S. or Ph.D. degrees in agriculture and climate sciences to be able to communicate scientific findings effectively to non-scientific audiences. Unfortunately, university graduate curricula rarely adequately prepare students with these important skills. REACCH recognizes the need for graduate students to have thorough exposure to other disciplines and to be able to communicate information for outreach and education purposes. These priorities have been incorporated into graduate training within the REACCH project. The interdisciplinary nature of the project and its sophisticated digital infrastructure provide graduate students multiple opportunities to gain these experiences. The project includes over 30 graduate students from 20 different disciplines and research foci including agronomy, biogeochemistry, soil quality, conservation tillage, hydrology, pest and beneficial organisms, economics, modeling, remote sensing, science education and climate science. Professional develop workshops were developed and held during annual project meetings to enhance student training. The "Toolbox" survey ( was used to achieve effective interdisciplinary communication. Interdisciplinary extension and education projects were required to allow students to gain experience with collaboration and working with stakeholder groups. Results of student surveys and rubrics developed to gauge success in interdisciplinary research and communication may provide a helpful starting point for

  10. The USA-National Phenology Network Biophysical Program (United States)

    Losleben, M. V.; Crimmins, T. M.; Weltzin, J. F.


    On January 1, 2009, the USA National Phenology Network (USA-NPN, launched the USA-NPN Biophysical Program. The overarching goal of the Biophysical Program (BP) is to link phenology, the study of recurring plant and animal life cycle stages, with climate through the integration of phenology observations, meteorological, and spectral remote sensing measurements at sites across a broad a spectrum of environments. Phenology is critical for understanding a changing world. Many of the recurring plant and animal life cycle stages such as leafing and flowering of plants, maturation of agricultural crops, emergence of insects, and migration of birds are sensitive to climatic variation and change, and are simple to observe and record. Such changes can effect, for example, timing mismatches between the emergence of food sources and the arrival of migrating populations, or create new disease and invasive species vectors via increasingly suitable growing seasons relative to the climatic life cycle requirements of hosts or the organisms themselves. New vectors or crashing populations can have major repercussions on entire ecosystems and regional economics. Thus, to track phenology and build a national database, the USA-NPN is providing standard phenology monitoring protocols. Further, the integration of weather stations with phenological data provides an opportunity to understand how a changing climate is altering phenology. Thus, the USA-NPN Biophysical Program is developing an integrative biology-climate site template for widespread dissemination, in collaboration with the Rocky Mountain Biological Laboratory (RMBL, This poster presents the USA-NPN Biophysical Program, and the results of the collaboration with RMBL during the summer of 2009, including the installation of an elevational network of climate stations.

  11. Biophysical Regulation of Vascular Differentiation and Assembly

    CERN Document Server

    Gerecht, Sharon


    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...

  12. Biophysical Modeling of Respiratory Organ Motion (United States)

    Werner, René

    Methods to estimate respiratory organ motion can be divided into two groups: biophysical modeling and image registration. In image registration, motion fields are directly extracted from 4D ({D}+{t}) image sequences, often without concerning knowledge about anatomy and physiology in detail. In contrast, biophysical approaches aim at identification of anatomical and physiological aspects of breathing dynamics that are to be modeled. In the context of radiation therapy, biophysical modeling of respiratory organ motion commonly refers to the framework of continuum mechanics and elasticity theory, respectively. Underlying ideas and corresponding boundary value problems of those approaches are described in this chapter, along with a brief comparison to image registration-based motion field estimation.

  14. Creative Climate: A global ten-year communications, research and learning project about environmental change (United States)

    Brandon, M. A.; Smith, J.


    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

  15. Biophysics of Cell Membrane Lipids in Cancer Drug Resistance: Implications for Drug Transport and Drug Delivery with Nanoparticles (United States)

    Peetla, Chiranjeevi; Vijayaraghavalu, Sivakumar; Labhasetwar, Vinod


    In this review, we focus on the biophysics of cell membrane lipids, particularly when cancers develop acquired drug resistance, and how biophysical changes in resistant cell membrane influence drug transport and nanoparticle-mediated drug delivery. Recent advances in membrane lipid research show the varied roles of lipids in regulating membrane P-glycoprotein function, membrane trafficking, apoptotic pathways, drug transport, and endocytic functions, particularly endocytosis, the primary mechanism of cellular uptake of nanoparticle-based drug delivery systems. Since acquired drug resistance alters lipid biosynthesis, understanding the role of lipids in cell membrane biophysics and its effect on drug transport is critical for developing effective therapeutic and drug delivery approaches to overcoming drug resistance. Here we discuss novel strategies for (a) modulating the biophysical properties of membrane lipids of resistant cells to facilitate drug transport and regain endocytic function and (b) developing effective nanoparticles based on their biophysical interactions with membrane lipids to enhance drug delivery and overcome drug resistance.

  16. Biophysical shunt theory for neuropsychopathology: Part I. (United States)

    Naisberg, Y; Avnon, M; Weizman, A


    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.

  17. Global energy modeling - A biophysical approach

    Energy Technology Data Exchange (ETDEWEB)

    Dale, Michael


    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.

  1. 'Communicate to vaccinate' (COMMVAC. building evidence for improving communication about childhood vaccinations in low- and middle-income countries: protocol for a programme of research

    Directory of Open Access Journals (Sweden)

    Lewin Simon


    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

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

  3. NASA/DOD Aerospace Knowledge Diffusion Research Project. Paper 38: Computer Mediated Communication (CMC) and the communication of technical information in aerospace (United States)

    Murphy, Daniel J.; Pinelli, Thomas E.


    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.

  4. On Effective Graphic Communication of Health Inequality: Considerations for Health Policy Researchers. (United States)

    Asada, Yukiko; Abel, Hannah; Skedgel, Chris; Warner, Grace


    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

  11. A systematic review of research into aided AAC to increase social-communication functions in children with autism spectrum disorder. (United States)

    Logan, Kristy; Iacono, Teresa; Trembath, David


    Augmentative and alternative communication (AAC) interventions have been shown to be effective in supporting children with autism spectrum disorder (ASD) to communicate, particularly to request preferred items and activities. The aim of this systematic review was to examine the effectiveness of AAC interventions in supporting children to produce a broader range of communicative functions and determine the extent to which these interventions have been evaluated beyond immediate effectiveness to address maintenance, generalization, and social validity. A systematic search and application of inclusion criteria yielded 30 interventions that focused on communication functions beyond object requests. In many of the studies, flaws detracted from the certainty of evidence, and maintenance, generalization, and/or social validity were not addressed. Further research is needed to evaluate the extent to which AAC interventions can support children with ASD to communicate using a variety of communication functions, as well as to demonstrate sustained, transferable, and meaningful change.

  12. Explaining variance and identifying predictors of children's communication via a multilevel model of single-case design research. (United States)

    Ottley, Jennifer Riggie; Ferron, John M; Hanline, Mary Frances


    The purpose of this study was to explain the variability in data collected from a single-case design study and to identify predictors of communicative outcomes for children with developmental delays or disabilities (n = 4). Using SAS University Edition, we fit multilevel models with time nested within children. Children's initial levels of communication and teachers' frequency of strategy use when directed at the children predicted children's communicative outcomes. These results indicate that teachers' implementation of evidence-based communication strategies, when directed toward children with disabilities, and the interaction between their use of the strategies and children's initial levels of communication predict children's communicative outcomes. Implications for research and practice are provided.

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

    Directory of Open Access Journals (Sweden)

    Shelton A. Gunaratne


    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.

  1. Public figure announcements about cancer and opportunities for cancer communication: a review and research agenda. (United States)

    Noar, Seth M; Willoughby, Jessica Fitts; Myrick, Jessica Gall; Brown, Jennifer


    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.

  3. Communicating Gender-Equality Progress, Reduces Social Identity Threats for Women Considering a Research Career

    Directory of Open Access Journals (Sweden)

    Una Tellhed


    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.

  4. What researchers told us about their experiences and expectations of scholarly communications ecosystems

    Directory of Open Access Journals (Sweden)

    Lorraine Estelle


    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.

  5. A Study of the Information Seeking Behavior of Communication Graduate Students in Their Research Processes

    Shih-Chuan Chen


    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.

  6. Experiences in Conducting Participatory Communication Research for HIV Prevention Globally: Translating Critical Dialog into Action through Action Media. (United States)

    Parker, Warren Martin; Becker-Benton, Antje


    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

    Reich, Daniel; Robbins, Mark; Leheny, Robert; Wonnell, Steven


    Over the past several years we have developed a two-semester second-year physics course sequence for students in the biosciences, tailored in part to the needs of undergraduate biophysics majors. One semester, ``Biological Physics,'' is based on the book of that name by P. Nelson. This talk will focus largely on the other semester, ``Wave Phenomena with Biophysical Applications,'' where we provide a novel introduction to the physics of waves, primarily through the study of experimental probes used in the biosciences that depend on the interaction of electromagnetic radiation with matter. Topic covered include: Fourier analysis, sound and hearing, diffraction - culminating in an analysis of x-ray fiber diffraction and its use in the determination of the structure of DNA - geometrical and physical optics, the physics of modern light microscopy, NMR and MRI. Laboratory exercises tailored to this course will also be described.

  10. Handbook of Single-Molecule Biophysics

    CERN Document Server

    Hinterdorfer, Peter


    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...

    This study was undertaken to develop conceptual designs for a manned, space shuttle sortie mission laboratory capable of supporting a wide variety of experiments in conjunction with communications and navigation research. This space/laboratory would be one in which man may effectively increase experiment efficiency by certain observations, modifications, setup, calibration, and limited maintenance steps. In addition, man may monitor experiment progress and perform preliminary data evaluation to verify proper equipment functioning and may terminate or redirect experiments to obtain the most desirable end results. The flexibility and unique capabilities of man as an experimenter in such a laboratory will add greatly to the simplification of space experiments and this provides the basis for commonality in many of the supportive subsystems, thus reaping the benefits of reusability and reduced experiment costs.

  13. Strategy for an Australian research program into possible health issues associated with exposure to communications radiofrequencies

    International Nuclear Information System (INIS)

    Roy, C.R.; Barnett, S.B.; Lokan, K.H.; Kossoff, G.; Anderson, H.


    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

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

    Pulwarty, R.; Cohen, S. J.


    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

  15. Biophysical Aspects of Transmembrane Signaling

    CERN Document Server

    Damjanovich, Sandor


    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...

  16. Biophysics at the Boundaries: The Next Problem Sets (United States)

    Skolnick, Malcolm


    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

  20. A biophysical analysis of latitudinal tree line (United States)

    Goetz, S. J.; Loranty, M. M.; Berner, L.; Jin, Y.; Randerson, J. T.


    Northern latitudinal tree line represents the interface between boreal forests and tundra ecosystems, and is the ecophysiological limit of tree recruitment and persistence. The transition between tundra and forest is typically gradual, occurring over tens to hundreds of kilometers. This gradient represents a substantial change in the biophysical properties of the earth surface, one that is particularly important in ecosystems that are snow covered for much of the year. Tree line is, however, commonly delineated by the point of the northern most tree, with no gradient between forested and non-forested ecosystems. As a consequence crisp delineations of tree line incorporated into models introduce error in surface radiation budgets due to inaccurate albedo representations. Errors in modeled carbon and water fluxes are likely as well. Here we use satellite observations to quantify several key biophysical properties across latitudinal tree line for a series of sites throughout the pan-boreal region We find decreases in NDVI and increases in albedo across the transition from boreal forest to tundra, as expected. However, in the absence of topographical barriers we find that these transitions can occur over upwards of 100 km, and that biophysical properties characteristic of tundra ecosystems can occur as far as 100 km south of tree line. This suggests that land surface models likely overestimate surface radiation budgets and carbon fluxes in the boreal biome. We discuss our results in the context of land surface models, noting specific examples from archived model runs.

    James Absher


    Studies that employ communication theories are rare in recreation resource management. One reason may be unfamiliarity with communication theories and their potential to provide useful results. A two-dimensional metatheoretical plane is proposed, selected recreation and communication theories are located in it, and functional comparisons are made among eight disparate...

  3. Biotic games and cloud experimentation as novel media for biophysics education (United States)

    Riedel-Kruse, Ingmar; Blikstein, Paulo


    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.

  5. Research on spatial features of streets under the influence of immersion communication technology brought by new media (United States)

    Xu, Hua-wei; Feng, Chen


    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.

  6. Check the box that best describes you: reflexively managing theory and praxis in LGBTQ health communication research. (United States)

    Goins, Elizabeth S; Pye, Danee


    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.

  7. Measuring (bio)physical tree properties using accelerometers (United States)

    van Emmerik, Tim; Steele-Dunne, Susan; Hut, Rolf; Gentine, Pierre; Selker, John; van de Giesen, Nick


    Trees play a crucial role in the water, carbon and nitrogen cycle on local, regional and global scales. Understanding the exchange of heat, water, and CO2 between trees and the atmosphere is important to assess the impact of drought, deforestation and climate change. Unfortunately, ground measurements of tree dynamics are often expensive, or difficult due to challenging environments. We demonstrate the potential of measuring (bio)physical properties of trees using robust and affordable acceleration sensors. Tree sway is dependent on e.g. mass and wind energy absorption of the tree. By measuring tree acceleration we can relate the tree motion to external loads (e.g. precipitation), and tree (bio)physical properties (e.g. mass). Using five months of acceleration data of 19 trees in the Brazilian Amazon, we show that the frequency spectrum of tree sway is related to mass, precipitation, and canopy drag. This presentation aims to show the concept of using accelerometers to measure tree dynamics, and we acknowledge that the presented example applications is not an exhaustive list. Further analyses are the scope of current research, and we hope to inspire others to explore additional applications.

  8. Climate Change Effects on Agriculture: Economic Responses to Biophysical Shocks (United States)

    Nelson, Gerald C.; Valin, Hugo; Sands, Ronald D.; Havlik, Petr; Ahammad, Helal; Deryng, Delphine; Elliott, Joshua; Fujimori, Shinichiro; Hasegawa, Tomoko; Heyhoe, Edwina


    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.

  10. Biophysical aspects of human thermoregulation during heat stress. (United States)

    Cramer, Matthew N; Jay, Ollie


    Humans maintain a relatively constant core temperature through the dynamic balance between endogenous heat production and heat dissipation to the surrounding environment. In response to metabolic or environmental disturbances to heat balance, the autonomic nervous system initiates cutaneous vasodilation and eccrine sweating to facilitate higher rates of dry (primarily convection and radiation) and evaporative transfer from the body surface; however, absolute heat losses are ultimately governed by the properties of the skin and the environment. Over the duration of a heat exposure, the cumulative imbalance between heat production and heat dissipation leads to body heat storage, but the consequent change in core temperature, which has implications for health and safety in occupational and athletic settings particularly among certain clinical populations, involves a complex interaction between changes in body heat content and the body's morphological characteristics (mass, surface area, and tissue composition) that collectively determine the body's thermal inertia. The aim of this review is to highlight the biophysical aspects of human core temperature regulation by outlining the principles of human energy exchange and examining the influence of body morphology during exercise and environmental heat stress. An understanding of the biophysical factors influencing core temperature will enable researchers and practitioners to better identify and treat individuals/populations most vulnerable to heat illness and injury during exercise and extreme heat events. Further, appropriate guidelines may be developed to optimize health, safety, and work performance during heat stress. Copyright © 2016 Elsevier B.V. All rights reserved.

  11. EuroStemCell: A European infrastructure for communication and engagement with stem cell research. (United States)

    Barfoot, Jan; Doherty, Kate; Blackburn, C Clare


    EuroStemCell is a large and growing network of organizations and individuals focused on public engagement with stem cells and regenerative medicine - a fluid and contested domain, where scientific, political, ethical, legal and societal perspectives intersect. Rooted in the European stem cell research community, this project has developed collaborative and innovative approaches to information provision and direct and online engagement, that reflect and respond to the dynamic growth of the field itself. EuroStemCell started as the communication and outreach component of a research consortium and subsequently continued as a stand-alone engagement initiative. The involvement of established European stem cell scientists has grown year-on-year, facilitating their participation in public engagement by allowing them to make high-value contributions with broad reach. The project has now had sustained support by partners and funders for over twelve years, and thus provides a model for longevity in public engagement efforts. This paper considers the evolution of the EuroStemCell project in response to - and in dialogue with - its evolving environment. In it, we aim to reveal the mechanisms and approaches taken by EuroStemCell, such that others within the scientific community can explore these ideas and be further enabled in their own public engagement endeavours.

  13. Young men's health promotion and new information communication technologies: illuminating the issues and research agendas. (United States)

    Robinson, Mark; Robertson, Steve


    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.

  14. Research on large-aperture primary mirror supporting way of vehicle-mounted laser communication system (United States)

    Meng, Lixin; Meng, Lingchen; Zhang, Yiqun; Zhang, Lizhong; Liu, Ming; Li, Xiaoming


    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.

  15. Social and Biophysical Predictors of Public Perceptions of Extreme Fires (United States)

    Hall, T. E.; Kooistra, C. M.; Paveglio, T.; Gress, S.; Smith, A. M.


    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

  18. Learning in context: identifying gaps in research on the transfer of medical communication skills to the clinical workplace. (United States)

    van den Eertwegh, Valerie; van Dulmen, Sandra; van Dalen, Jan; Scherpbier, Albert J J A; van der Vleuten, Cees P M


    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.

  19. From Research to Practice: Increasing Ability of Practitioners to Relate Family-of-Origin Communicative Techniques to Current Marital Satisfaction

    Directory of Open Access Journals (Sweden)

    Claire Kimberly


    Full Text Available Research has shown a connection between family-of-origin communicative techniques and later marital satisfaction. However, little has been done to see how this information can be incorporated in family life education settings. The purpose of this study is to make a connection between research and practice by testing the validity of easy-to-use measurements informing this relationship. The results of a survey from 649 married individuals about the communicative practices within their family-of-origin and in their current marriage support the ability of practitioners to understand techniques utilized in marriage by interpreting those used in childhood. By associating the literature between family-of-origin communication and marital dynamics in a practical way, practitioners and educators will be better able to assess and assist married couples in therapeutic or educational settings.

  20. Communication in bottlenose dolphins: 50 years of signature whistle research. (United States)

    Janik, Vincent M; Sayigh, Laela S


    Bottlenose dolphins (Tursiops truncatus) produce individually distinctive signature whistles that broadcast the identity of the caller. Unlike voice cues that affect all calls of an animal, signature whistles are distinct whistle types carrying identity information in their frequency modulation pattern. Signature whistle development is influenced by vocal production learning. Animals use a whistle from their environment as a model, but modify it, and thus invent a novel signal. Dolphins also copy signature whistles of others, effectively addressing the whistle owner. This copying occurs at low rates and the resulting copies are recognizable as such by parameter variations in the copy. Captive dolphins can learn to associate novel whistles with objects and use these whistles to report on the presence or absence of the object. If applied to signature whistles, this ability would make the signature whistle a rare example of a learned referential signal in animals. Here, we review the history of signature whistle research, covering definitions, acoustic features, information content, contextual use, developmental aspects, and species comparisons with mammals and birds. We show how these signals stand out amongst recognition calls in animals and how they contribute to our understanding of complexity in animal communication.

  1. Communicating research with the public: evaluation of an invasive earthworm education program

    Directory of Open Access Journals (Sweden)

    Erin Cameron


    Full Text Available Ecologists are increasingly encouraged by funding agencies and professional societies to communicate their research with the public. However, most receive relatively little training in how to do this effectively. Furthermore, evaluation of whether such an investment by ecologists actually achieves conservation objectives is rare. We created an education program, involving print, television, radio, and internet media, to increase awareness about earthworm invasions and to discourage anglers from dumping earthworm bait. Using pre- and post-surveys, we evaluated our program’s success in reaching its target audience and in changing knowledge and behavior. Few participants (4.1% recalled seeing the program material and knowledge of the fact that earthworms are non-native in Alberta remained low (15.8% before, 15.1% after. Further, after being told about the negative effects of earthworms in forests, 46.7% of the anglers surveyed stated they would not change their bait disposal behavior in the future, with many commenting that they did not believe earthworms could be harmful. These results highlight the importance of evaluating education programs, rather than assuming they are successful. Given many participants’ doubts that earthworms have negative effects, both regulations and education may be needed to reduce earthworm introductions.

    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)

  3. Common solutions for power, communication and robustness in operations of large measurement networks within Research Infrastructures (United States)

    Huber, Robert; Beranzoli, Laura; Fiebig, Markus; Gilbert, Olivier; Laj, Paolo; Mazzola, Mauro; Paris, Jean-Daniel; Pedersen, Helle; Stocker, Markus; Vitale, Vito; Waldmann, Christoph


    European Environmental Research Infrastructures (RI) frequently comprise in situ observatories from large-scale networks of platforms or sites to local networks of various sensors. Network operation is usually a cumbersome aspect of these RIs facing specific technological problems related to operations in remote areas, maintenance of the network, transmission of observation values, etc.. Robust inter-connection within and across these networks is still at infancy level and the burden increases with remoteness of the station, harshness of environmental conditions, and unavailability of classic communication systems, which is a common feature here. Despite existing RIs having developed ad-hoc solutions to overcome specific problems and innovative technologies becoming available, no common approach yet exists. Within the European project ENVRIplus, a dedicated work package aims to stimulate common network operation technologies and approaches in terms of power supply and storage, robustness, and data transmission. Major objectives of this task are to review existing technologies and RI requirements, propose innovative solutions and evaluate the standardization potential prior to wider deployment across networks. Focus areas within these efforts are: improving energy production and storage units, testing robustness of RI equipment towards extreme conditions as well as methodologies for robust data transmission. We will introduce current project activities which are coordinated at various levels including the engineering as well as the data management perspective, and explain how environmental RIs can benefit from the developments.

  4. Action research, simulation, team communication, and bringing the tacit into voice society for simulation in healthcare. (United States)

    Forsythe, Lydia


    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.

  5. Why Health Care Needs Design Research: Broadening the Perspective on Communication in Pediatric Care Through Play. (United States)

    Knutz, Eva; Ammentorp, Jette; Kofoed, Poul-Erik


    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.

  15. A proposal of new nuclear communication scheme based on qualitative research

    International Nuclear Information System (INIS)

    Yagi, Ekou; Takahashi, Makoto; Kitamura, Masaharu


    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)

  19. Improving family carers' experiences of support at the end of life by enhancing communication: an action research study. (United States)

    Dosser, Isabel; Kennedy, Catriona


    This paper builds on findings from phase one of a participatory action research study, which investigated support for family carers at the end of life in an acute hospital setting in Scotland, UK ( Dosser and Kennedy, 2012 ). The research presented here is the second phase of the participatory action research study, in which nursing staff from an acute hospital ward are involved in ongoing analysis of data and ideas guided by action cycles and reflection. Two key change initiatives are reported; improving nurses' communication skills and improving the environment for family carers of loved ones at the end of life within the acute hospital setting. To address these points, nurses were enrolled on a communications skills course, and a new room for family carers was integrated into the hospital. Data were analysed from interviews and questionnaires with the nurses, and from insights gathered in a reflective diary taken by the researcher. The changes implemented improved the confidence of participants in communicating with carers as well as patients and colleagues. The findings highlight practical strategies and communication issues that can potentially impact on the grief experience of family carers, such as having a safe space nearby to rest in private, away from the bedside.

  2. Communication technology access, use, and preferences among primary care patients: from the Residency Research Network of Texas (RRNeT). (United States)

    Hill, Jason H; Burge, Sandra; Haring, Anna; Young, Richard A


    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.

  3. A Network Analysis of the Teachers and Graduate Students’ Research Topics in the Field of Mass Communication

    Directory of Open Access Journals (Sweden)

    Ming-Shu Yuan


    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.

  4. Modeling disordered protein interactions from biophysical principles.

    Directory of Open Access Journals (Sweden)

    Lenna X Peterson


    Full Text Available Disordered protein-protein interactions (PPIs, those involving a folded protein and an intrinsically disordered protein (IDP, are prevalent in the cell, including important signaling and regulatory pathways. IDPs do not adopt a single dominant structure in isolation but often become ordered upon binding. To aid understanding of the molecular mechanisms of disordered PPIs, it is crucial to obtain the tertiary structure of the PPIs. However, experimental methods have difficulty in solving disordered PPIs and existing protein-protein and protein-peptide docking methods are not able to model them. Here we present a novel computational method, IDP-LZerD, which models the conformation of a disordered PPI by considering the biophysical binding mechanism of an IDP to a structured protein, whereby a local segment of the IDP initiates the interaction and subsequently the remaining IDP regions explore and coalesce around the initial binding site. On a dataset of 22 disordered PPIs with IDPs up to 69 amino acids, successful predictions were made for 21 bound and 18 unbound receptors. The successful modeling provides additional support for biophysical principles. Moreover, the new technique significantly expands the capability of protein structure modeling and provides crucial insights into the molecular mechanisms of disordered PPIs.

  6. Education research: communication skills for neurology residents: structured teaching and reflective practice. (United States)

    Watling, Christopher J; Brown, Judith B


    Despite the importance of communication skills for neurologists, specific training in this area at the residency level is often lacking. This study aimed to enhance learning of these skills and to encourage reflective practice around communication skills. A group of 12 neurology residents participated in a series of six case-based communication skills workshops. Each workshop focused on a particular clinical scenario, including breaking bad news, discussing do-not-resuscitate orders, communicating with "difficult" patients, disclosing medical errors, obtaining informed consent for neurologic tests and procedures, and discussing life-and-death decisions with families of critically ill patients. Residents also kept reflective portfolios in which real examples of these interactions were recorded. The program was well accepted, and residents rated the workshops as effective and relevant to their practice. Analysis of residents' portfolios revealed three themes relevant to patient-physician communication: 1) communication is more successful when adequate time is allowed, 2) the ability to empathize with patients and their families is essential to successful interactions, and 3) the development of specific approaches to challenging scenarios can facilitate effective interactions. The portfolios also demonstrated that residents would engage in reflective practice. Targeting of communication skills training around specific clinical scenarios using neurologic cases was well accepted and was deemed relevant to practice. The use of portfolios may promote lifelong learning in this area.

  7. Biophysical characterization of antibodies with isothermal titration calorimetry

    Directory of Open Access Journals (Sweden)

    Verna Frasca


    Full Text Available Antibodies play a key role in the immune response. Since antibodies bind antigens with high specificity and tight affinity, antibodies are an important reagent in experimental biology, assay development, biomedical research and diagnostics. Monoclonal antibodies are therapeutic drugs and used for vaccine development. Antibody engineering, biophysical characterization, and structural data have provided a deeper understanding of how antibodies function, and how to make better drugs. Isothermal titration calorimetry (ITC is a label-free binding assay, which measures affinity, stoichiometry, and binding thermodynamics for biomolecular interactions. When thermodynamic data are used together with structural and kinetic data from other assays, a complete structure-activity-thermodynamics profile can be constructed. This review article describes ITC, and discusses several applications on how data from ITC provides insights into how antibodies function, guide antibody engineering, and aid design of new therapeutic drugs.

  8. TOPICAL REVIEW: The physics, biophysics and technology of photodynamic therapy (United States)

    Wilson, Brian C.; Patterson, Michael S.


    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.

  12. Do patients and health care professionals view the communication processes of clinical research differently? A Rasch analysis from a survey. (United States)

    González-de Paz, Luis; Kostov, Belchin; Solans-Julian, Pilar; Navarro-Rubio, M Dolores; Sisó-Almirall, Antoni


    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.

  13. Small Business Demand Response with Communicating Thermostats: SMUD's Summer Solutions Research Pilot

    Energy Technology Data Exchange (ETDEWEB)

    Herter, Karen; Wayland, Seth; Rasin, Josh


    This report documents a field study of 78 small commercial customers in the Sacramento Municipal Utility District service territory who volunteered for an integrated energy-efficiency/demand-response (EE-DR) program in the summer of 2008. The original objective for the pilot was to provide a better understanding of demand response issues in the small commercial sector. Early findings justified a focus on offering small businesses (1) help with the energy efficiency of their buildings in exchange for occasional load shed, and (2) a portfolio of options to meet the needs of a diverse customer sector. To meet these expressed needs, the research pilot provided on-site energy efficiency advice and offered participants several program options, including the choice of either a dynamic rate or monthly payment for air-conditioning setpoint control. An analysis of hourly load data indicates that the offices and retail stores in our sample provided significant demand response, while the restaurants did not. Thermostat data provides further evidence that restaurants attempted to precool and reduce AC service during event hours, but were unable to because their air-conditioning units were undersized. On a 100 F reference day, load impacts of all participants during events averaged 14%, while load impacts of office and retail buildings (excluding restaurants) reached 20%. Overall, pilot participants including restaurants had 2007-2008 summer energy savings of 20% and bill savings of 30%. About 80% of participants said that the program met or surpassed their expectations, and three-quarters said they would probably or definitely participate again without the $120 participation incentive. These results provide evidence that energy efficiency programs, dynamic rates and load control programs can be used concurrently and effectively in the small business sector, and that communicating thermostats are a reliable tool for providing air-conditioning load shed and enhancing the ability

    Full Text Available Presenting interests for the most various sciences (cybernetics, economics, ethnology, philosophy, history, psycho-sociology etc., the complex communication process incited and triggered a lot of opinions, many of them not complementary at all and even taken to the level of some passions generating contradictions. The result was the conceptualization of the content and of the communication functions on different forms called models by their creators. In time, with their evolution, the communication models have included, besides some basic elements (sender, message, means of communication, receiver and effect also a range of detail elements essential to streamline the process itself: the noise source , codec and feedback, the interaction of the field specific experience of the transmitter and receptor, the organizational context of communication and communication skills, including how to produce and interpretate these ones. Finally, any model’ functions are either heuristic (to explain, organizational (to order or predictive (making assumptions. They are worth only by their degree of probability remaining valid so long as it is not invalidated by practice and is one way of describing reality and not the reality itself. This is the context in which our work, the first of its kind in Romania, proposes in the context of improving organizational management, two new models of communication at both the micro- and macro- economic, models through which, using crowdsourcing, the units in the tourism, hospitality and leisure industry (THLI will be able to communicate more effectively, based not on own insights and / or perceptions but, firstly, on the views of management and experts in the field and especially on the customer’ feedback.

  19. The Stakeholder Model of voice research: Acknowledging barriers to human rights of all stakeholders in a communicative exchange. (United States)

    Madill, Catherine; Warhurst, Samantha; McCabe, Patricia


    The act of communication is a complex, transient and often abstract phenomenon that involves many stakeholders, each of whom has their own perspective: the speaker, the listener, the observer and the researcher. Current research practices in voice disorder are frequently framed through a single lens - that of the researcher/clinician or their participant/patient. This single lens approach risks overlooking significant barriers to the basic human right of freedom of expression for those with a voice disorder as it omits consideration of the impact of voice disorder on the listener, and consideration of the wider impact of the voice in the occupational context. Recent research in the area of voice has developed a multiple lens and subsequent Stakeholder Model that acknowledges the experience and reality of multiple stakeholders viewing the same phenomenon, the voice. This research paradigm is built on Article 19 of the Universal Declaration of Human Rights as it considers the realities of all stakeholders in forming a deeper understanding of the causality, impact and aspects of communication disorder. The Stakeholder Model will be presented as a suggestion for future investigations of communication disorders more widely.

    Previously a novel chaos M-ary digital communication method based on spatiotemporal chaos Hamilton oscillator has been proposed. Without chaos synchronization circumstance, it has performance improvement in bandwidth efficiency, transmission efficiency and anti-white-noise performance compared with traditional communication method. In this paper, the channel noise influence on chaotic modulation signals and the construction problem of anti-color-noise chaotic M-ary communication system are studied. The formula of zone partition demodulator’s boundary in additive white Gaussian noise is derived, besides, the problem about how to determine the boundary of zone partition demodulator in additive color noise is deeply studied; Then an approach on constructing anti-color-noise chaos M-ary communication system is proposed, in which a pre-distortion filter is added after the chaos baseband modulator in the transmitter and whitening filter is added before zone partition demodulator in the receiver. Finally, the chaos M-ary communication system based on Hamilton oscillator is constructed and simulated in different channel noise. The result shows that the proposed method in this paper can improve the anti-color-noise performance of the whole communication system compared with the former system, and it has better anti-fading and resisting disturbance performance than Quadrature Phase Shift Keying system.

  1. Research on the Relationship between Internal Communication Climate and Job Satisfaction and Employee Loyalty

    Directory of Open Access Journals (Sweden)

    Tamara Sušanj Šulentić


    Full Text Available Successful organizations dedicate considerable attention to the quality of internal communications, which have a proven potential to contribute to creating competitive advantages in an increasingly demanding market. Internal communications have become a crucial prerequisite in creating new value to ensure customer and employee satisfaction. The purpose of this paper was to establish possible correlations between certain factors of the communication climate, and employee satisfaction and loyalty. The data used in this paper were collected by means of an employee survey, conducted in a pharmaceutical company immediately after it had undergone strategic changes, resulting from its new ownership structure and organizational culture. The factor analysis indicates five key factors of the communication climate: the availability of information about corporate activities as perceived by employees; satisfaction with co-workers; perceived job stability; perceived job importance within the organization and a perceived sense of injustice. The regression analysis confirmed a positive correlation between a good communication climate and the employee satisfaction and loyalty during strategic organizational changes. This is an important piece of information for all those having doubts about how to communicate strategic changes.

  2. A synthesized biophysical and social vulnerability assessment for Taiwan (United States)

    Lee, Yung-Jaan


    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.

  3. Examining emergency department communication through a staff-based participatory research method: identifying barriers and solutions to meaningful change. (United States)

    Cameron, Kenzie A; Engel, Kirsten G; McCarthy, Danielle M; Buckley, Barbara A; Mercer Kollar, Laura Min; Donlan, Sarah M; Pang, Peter S; Makoul, Gregory; Tanabe, Paula; Gisondi, Michael A; Adams, James G


    We test an initiative with the staff-based participatory research (SBPR) method to elicit communication barriers and engage staff in identifying strategies to improve communication within our emergency department (ED). ED staff at an urban hospital with 85,000 ED visits per year participated in a 3.5-hour multidisciplinary workshop. The workshop was offered 6 times and involved: (1) large group discussion to review the importance of communication within the ED and discuss findings from a recent survey of patient perceptions of ED-team communication; (2) small group discussions eliciting staff perceptions of communication barriers and best practices/strategies to address these challenges; and (3) large group discussions sharing and refining emergent themes and suggested strategies. Three coders analyzed summaries from group discussions by using latent content and constant comparative analysis to identify focal themes. A total of 127 staff members, including attending physicians, residents, nurses, ED assistants, and secretaries, participated in the workshop (overall participation rate 59.6%; range 46.7% to 73.3% by staff type). Coders identified a framework of 4 themes describing barriers and proposed interventions: (1) greeting and initial interaction, (2) setting realistic expectations, (3) team communication and respect, and (4) information provision and delivery. The majority of participants (81.4%) reported that their participation would cause them to make changes in their clinical practice. Involving staff in discussing barriers and facilitators to communication within the ED can result in a meaningful process of empowerment, as well as the identification of feasible strategies and solutions at both the individual and system levels.

  4. Engaging Adolescents Through Participatory and Qualitative Research Methods to Develop a Digital Communication Intervention to Reduce Adolescent Obesity. (United States)

    Livingood, William C; Monticalvo, David; Bernhardt, Jay M; Wells, Kelli T; Harris, Todd; Kee, Kadra; Hayes, Johnathan; George, Donald; Woodhouse, Lynn D


    The complexity of the childhood obesity epidemic requires the application of community-based participatory research (CBPR) in a manner that can transcend multiple communities of stakeholders, including youth, the broader community, and the community of health care providers. To (a) describe participatory processes for engaging youth within context of CBPR and broader community, (b) share youth-engaged research findings related to the use of digital communication and implications for adolescent obesity intervention research, and (c) describe and discuss lessons learned from participatory approaches. CBPR principles and qualitative methods were synergistically applied in a predominantly African American part of the city that experiences major obesity-related issues. A Youth Research Advisory Board was developed to deeply engage youth in research that was integrated with other community-based efforts, including an academic-community partnership, a city-wide obesity coalition, and a primary care practice research network. Volunteers from the youth board were trained to apply qualitative methods, including facilitating focus group interviews and analyzing and interpreting data with the goal of informing a primary care provider-based obesity reduction intervention. The primary results of these efforts were the development of critical insights about adolescent use of digital communication and the potential importance of messaging, mobile and computer apps, gaming, wearable technology, and rapid changes in youth communication and use of digital technology in developing adolescent nutrition and physical activity health promotion. The youth led work helped identify key elements for a digital communication intervention that was sensitive and responsive to urban youth. Many valuable lessons were also learned from 3 years of partnerships and collaborations, providing important insights on applying CBPR with minority youth populations.

  5. Disease-related everyday communication of persons with rheumatic and musculoskeletal diseases-Results of a participatory research project. (United States)

    Lamprecht, J; Thyrolf, A; Mattukat, K; Schöpf, A C; Schlöffel, M; Farin, E; Mau, W


    The aim of the present study is to describe and analyse significant factors of disease-related everyday communication of persons with RMDs in a nationwide project in Germany funded by the Deutsche Rheumaliga Bundesverband e.V. (German League against Rheumatism). In this participatory research project four persons with RMDs are involved. An online questionnaire addressing context, difficulties, and burden of disease-related everyday communication was answered by 1.015 persons with RMDs. Social and communication skills were recorded by questionnaires to capture social insecurity and patient communication competence. More than half of the participants reported difficulties in disease-related conversations across various situations. The majority of these persons suffer from this experience particularly in conversations at the work environment or with staff members of authorities. They feel unconfident especially in situations which require saying "no". Furthermore, compared to the general population persons with RMDs have more anxiety about contact with others. Strengthening the social skills of persons with RMDs in conversations related to everyday situations can promote a self-determined life and contribute to the maintenance of social participation. Based on the results, a communication skills training for persons with RMDs will be developed. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    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/m2. 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.

  10. Management of communication area in a nuclear research and development institute

    International Nuclear Information System (INIS)

    Soares, Wellington Antonio


    Nuclear energy to the general public is always associated to the production of nuclear weapons or to nuclear and radiological accidents. Public communication actions done by the National Commission of Nuclear Energy (CNEN) have been contributing to make known the social and peaceful applications of nuclear energy, reaching different kinds of public. Interaction programs with society and in particular with students have also been carried out by the Nuclear Technology Development Center (CDTN/CNEN). Measuring public communication results can help to show that financial resource in this area should be considered as investment and not as expenses. One needs therefore a well-established managing system. Fundamentals of the National Quality Award Criteria for Excellence - PNQ are being applied in the area in charge of business and public communication at CDTN. Systematic registration of results started in 2000 and a gradual increase in the number of means of communication for the internal public has occurred in the last five years. The Center has now a bimonthly newspaper edition. Communication indicators have shown an increasing number of students received in the Center or provided with lectures in schools. Results of satisfaction inquiry from these students show good results. The implemented management system has allowed informing the nature and quantity of people reached by the information on nuclear applications and the improvement in the institutional image. (author)

  11. Technological research of differential phase shift keying receiver in the satellite-to-ground laser communication (United States)

    Ma, Xiaoping; Sun, Jianfeng; Zhi, Yanan; Liu, Liren


    Laser communication links between satellite and ground remains a bottleneck problem that has not been solved in free space communication network now. Atmospheric disturbances have badly influenced the wave-front of signal light and destroyed the integrality of optical phase, so the bit error rate (BER) is increased at the receiving terminal in the space-to-ground laser communication. With conventional coherent reception, the contrast of coherent light increased dramatically, and transmission efficiency of Space to ground laser communication decreased. Receiving technology based on differential phase shift keying (DPSK) is proposed here to overcome the effects of atmosphere here. Differential phase shift keying without the integrality and compensation of the optical phases, is suited for high rate space to ground communication links due to its immunity of the wavefront of a beam passing atmosphere. A Mach-Zehnder delay interferometer is used for differential delay which is equal to the one bit period. The differential data information can be obtained from the optical phase changes. Differential phase modulation technique can be a promising optical receiving technology.

  12. Professor Nukem - communicating research in the age of the experience economy

    DEFF Research Database (Denmark)

    Sandvik, Kjetil; Thorhauge, Anne Mette

    The experience economy, that is, the creative and communicative turn in today's social, cultural and economic structures implies, as explained by Pine and Gilmour (1999), that consume is embedded in a communicational format that conveys some kind of experience to the consumer. The consumer in turn...... becomes more than just a passive user - she becomes an active participant in the experiential/communicational design. As such the mode of consume in the experience economy is an interactive and play-centric one. And the computer game embodies the very core logic of this experience economy....... In the experience economy focus is not on consume of commodities and services, but on the consumer's engagement in an experience which uses products, services and information as props and creative tools. Using the user-centered mode of consume as our point of departure, this paper examines how the computer game...

  13. From information to communication - the role of a nuclear research centre

    International Nuclear Information System (INIS)

    Legrain, Christian; Rabaste, Elisabeth


    Nuclear energy does not escape the rule of the information problem. We are living in a so-called information society, which also implies a certain disinformation, but at the same time an overinformation and a lack of information. The weight of the antinuclear pressure groups has become more and more important. The parties opposed to nuclear energy and the green parties in power are forcing a phase-out. In Sweden for instance political power has closed down Barsebaeck 1, in spite of the public opinion being in favour of maintaining the nuclear power plants. Under the pressure of the liberalisation of the electricity market in many European countries, the present leitmotiv is : Environment, Competitiveness and Safety. The decisions of phase-out in Germany and in Belgium are the issue of negotiations in 'rainbow' coalitions. In other countries, the non-governmental organisations have progressively relayed (or provoked) public fear and taken more and more weight. The importance attached to the position adopted by the NGO's at the Hague (COP6) is a typical example hereof. The presence of pressure groups is ever increasing and the initial talk is: p hase out of nuclear energy, then we will start discussing . Nuclear energy as seen by the NGO's, Greenpeace, Wise, etc. is not taken seriously, neither in the scope of a reduction of the greenhouse effect, nor in the respect of the three aforementioned aspects: environment, competitiveness and safety. Information and communication via a research centre is explained in more detail in case of Belgian SCK-CEN. Nuclear energy is not THE solution but constitutes PART of the solution in the global energy mix policy. Nuclear energy, as any other human activity, is not free of danger, it is a question of being transparent and of indicating the way how the aspects competitiveness (cost of the kWh, lifetime of the reactors..) but most of all environment (radiation, waste....) and safety (accidents) are managed. It should be emphasised

  14. Experimental research and comparison of LDPC and RS channel coding in ultraviolet communication systems. (United States)

    Wu, Menglong; Han, Dahai; Zhang, Xiang; Zhang, Feng; Zhang, Min; Yue, Guangxin


    We have implemented a modified Low-Density Parity-Check (LDPC) codec algorithm in ultraviolet (UV) communication system. Simulations are conducted with measured parameters to evaluate the LDPC-based UV system performance. Moreover, LDPC (960, 480) and RS (18, 10) are implemented and experimented via a non-line-of-sight (NLOS) UV test bed. The experimental results are in agreement with the simulation and suggest that based on the given power and 10(-3)bit error rate (BER), in comparison with an uncoded system, average communication distance increases 32% with RS code, while 78% with LDPC code.

However, the vulnerability and blemish of Tor affect system security. An identity and Signcryption-based concurrent signature scheme was used to prevent the behaviors of attackers from inserting controlled nodes and conspiring to make DDos attacks. The integrated security of Tor system was enhanced in our scheme. In addition we have proved the scheme.

  16. Research of Integrity and Authentication in OPC UA Communication Using Whirlpool Hash Function

    Directory of Open Access Journals (Sweden)

    Kehe Wu


    Full Text Available Currently, the demand for information security of industrial control systems is becoming more and more urgent, but the security model proposed by OPC UA cannot meet the practical requirements of industrial control systems. For this reason, this paper proposes a new security communication model to provide integrity and authentication in OPC UA. This model uses the Whirlpool hash function to check integrity and generates digital signature along with RSA in message transmission. Compared to SHA-1, Whirlpool has a higher calculation speed and lower collision rate. Through this model, terminals in the upper layer can communicate with field devices via a channel with high security and efficiency.

    The ECRAN (European Communication on Research Awareness Needs) project was initiated in 2012, with support from the European Commission, to improve public knowledge about the importance of independent, multinational, clinical trials in Europe. Participants in the ECRAN consortium included clinicians and methodologists directly involved in clinical trials; researchers working in partnership with the public and patients; representatives of patients; and experts in science communication. We searched for, and evaluated, relevant existing materials and developed additional materials and tools, making them freely available under a Creative Commons licence. The principal communication materials developed were: 1. A website ( ) in six languages, including a Media centre section to help journalists to disseminate information about the ECRAN project 2. An animated film about clinical trials, dubbed in the 23 official languages of the European Community, and an interactive tutorial 3. An inventory of resources, available in 23 languages, searchable by topic, author, and media type 4. Two educational games for young people, developed in six languages 5. Testing Treatments interactive in a dozen languages, including five official European Community languages 6. An interactive tutorial slide presentation testing viewers' knowledge about clinical trials Over a 2-year project, our multidisciplinary and multinational consortium was able to produce, and make freely available in many languages, new materials to promote public knowledge about the importance of independent and international clinical trials. Sustained funding for the ECRAN information platform could help to promote successful recruitment to independent clinical trials supported through the European Clinical Research Infrastructure Network.

  18. The Psychology of Climate Change Communication - Insights from the Center for Research on Environmental Decisions (CRED) (Invited) (United States)

    Marx, S.


    Natural scientists have made great strides in recent years to improve their understanding of the complex issue of global climate change. Despite the progress made, there continues to be a persistent gap between the knowledge and concern among members of the climate science community and translation of such scientific expertise into effective climate change policies and the general public’s behavioral choices. Communication is breaking down at the intersection of climate science, policy, and behavior change. Part of the reason is that, to date, social science research has not been sufficiently exploited to help individuals and groups incorporate information about climate change and environmental risk into decision making. The presentation will highlight research conducted at the Center for Research on Environmental Decisions (CRED). This presentation will discuss barriers to behavioral change and provide suggestions for improving communication about climate change: Typical science communication requires analytic processing, some level of expertise, at a minimum interest. For most people abstract information does not translate into powerful vivid images that would trigger action. Furthermore, we have found that people’s interpretation of scientific uncertainty can get in the way of using forecasts and projections. Other barriers include public risk perceptions and attitudes, cultural values, and myopia, as well as the importance that people place on self-interest/economic goals vs. collective interest/social goals. Many of these obstacles can be overcome and communication of climate change information can be improved by presenting a combination of affective information (vicarious experience, scenarios, narratives, and analogies) and scientific data; yet there are also downsides to the overuse of emotional appeals (such as the finite pool of worry and the single action bias); tapping into social affiliations and group identities can motivate the activation of

  10. Teaching students how to read and write science: a mandatory course on scientific research and communication in medicine. (United States)

    Marusić, Ana; Marusić, Matko


    The authors describe the development and introduction of a course on scientific methodology and communication into the medical curriculum in a country outside of the mainstream scientific world. As editors of a general medical journal in Croatia, they learned that their colleagues had important and interesting data but no skills for presenting them in a scientific article. To alleviate the lack of education in research methodology and writing, the authors developed and introduced a mandatory course in scientific methodology and communication into the medical curriculum of the largest Croatian medical school. The course is structured into lectures, medium-sized-group discussions, and problem-solving small-group work, and is focused on (1) principles of scientific research; (2) access to medical literature and bibliographic databases; (3) study design and analysis and presentation of data; (4) assessing and writing a scientific article; and (5) responsible conduct of research. The course has been running since 1995-96 and is already showing results, visible in the more positive attitude of students toward scientific research and evidence-based medicine, and a significant number of students working on research projects and publishing scientific papers. The authors and colleagues also run continuing education courses for young academic physicians and an annual advanced workshop on scientific writing, involving academic physicians from all of southeastern Europe. The long-term goal is to create a critical mass of academic physicians with critical appraisal skills needed for evidence-based medicine and with skills for effectively communicating their research to the international scientific community.

  11. A "CASE" Study on Developing Science Communication and Outreach Skills of University Graduate Student Researchers in Alaska (United States)

    Tedesche, M. E.; Conner, L.


    Well rounded scientific researchers are not only experts in their field, but can also communicate their work to a multitude of various audiences, including the general public and undergraduate university students. Training in these areas should ideally start during graduate school, but many programs are not preparing students to effectively communicate their work. Here, we present results from the NSF-funded CASE (Changing Alaska Science Education) program, which was funded by NSF under the auspices of the GK-12 program. CASE placed science graduate students (fellows) in K-12 classrooms to teach alongside of K-12 teachers with the goal of enhancing communication and teaching skills among graduate students. CASE trained fellows in inquiry-based and experiential techniques and emphasized the integration of art, writing, and traditional Alaska Native knowledge in the classroom. Such techniques are especially effective in engaging students from underrepresented groups. As a result of participation, many CASE fellows have reported increased skills in communication and teaching, as well as in time management. These skills may prove directly applicable to higher education when teaching undergraduate students.

  12. Rhizosphere biophysics and root water uptake (United States)

    Carminati, Andrea; Zarebanadkouki, Mohsen; Ahmed, Mutez A.; Passioura, John


    The flow of water into the roots and the (putative) presence of a large resistance at the root-soil interface have attracted the attention of plant and soil scientists for decades. Such resistance has been attributed to a partial contact between roots and soil, large gradients in soil matric potential around the roots, or accumulation of solutes at the root surface creating a negative osmotic potential. Our hypothesis is that roots are capable of altering the biophysical properties of the soil around the roots, the rhizosphere, facilitating root water uptake in dry soils. In particular, we expect that root hairs and mucilage optimally connect the roots to the soil maintaining the hydraulic continuity across the rhizosphere. Using a pressure chamber apparatus we measured the relation between transpiration rate and the water potential difference between soil and leaf xylem during drying cycles in barley mutants with and without root hairs. The samples were grown in well structured soils. At low soil moistures and high transpiration rates, large drops in water potential developed around the roots. These drops in water potential recovered very slowly, even after transpiration was severely decreased. The drops in water potential were much bigger in barley mutants without root hairs. These mutants failed to sustain high transpiration rates in dry conditions. To explain the nature of such drops in water potential across the rhizosphere we performed high resolution neutron tomography of the rhizosphere of the barleys with and without root hairs growing in the same soil described above. The tomograms suggested that the hydraulic contact between the soil structures was the highest resistance for the water flow in dry conditions. The tomograms also indicate that root hairs and mucilage improved the hydraulic contact between roots and soil structures. At high transpiration rates and low water contents, roots extracted water from the rhizosphere, while the bulk soil, due its

  13. Initiating New Science Partnerships in Rural Education (INSPIRE): Enhancing Scientific Communication by Bringing STEM Research into the Classroom (United States)

    Pierce, D.; Radencic, S.; Funderburk, W. K.; Walker, R. M.; Jackson, B. S.; Dawkins, K. S.; Schmitz, D.; Bruce, L. M.; McNeal, K.


    INSPIRE, a five-year partnership between Mississippi State University and three local school districts, is designed to strengthen the communication skills of graduate Fellows in geosciences, physics, astronomy, chemistry, and engineering as they incorporate their research into inquiry-based lessons in 7th - 12th grade science and math classrooms. All lesson plans designed and taught by the graduate Fellows must include one or more connections to their research, and these connections must be demonstrated to the students during the lessons. International research partnerships with Australia, the Bahamas, England, and Poland provide valuable opportunities for graduate Fellows to conduct field work abroad and allow our partner teachers to have authentic research experiences that they can bring back to their classrooms. Program effectiveness has been examined using pre- and post-year attitudinal surveys, formal lesson plan documents, Fellow and teacher journals, focus group meetings with a project evaluator, and direct observation of Fellow-led classroom activities. Analyses of data gathered during the past four years of the partnership will be presented that examine the diversity in approaches taken by Fellows to communicate big ideas, changes in the ability of Fellows to find connections between their research and classroom lessons while keeping them aligned with state and national standards, and the quality of the mentorship provided to the Fellows by our partner teachers. INSPIRE is funded by the Graduate K-12 (GK-12) STEM Fellowship Program of the National Science Foundation (Award No. DGE-0947419).

  14. Linking biophysical models and public preferences for ecosystem service assessments: a case study for the Southern Rocky Mountains (United States)

    Bagstad, Kenneth J.; Reed, James; Semmens, Darius J.; Sherrouse, Ben C.; Troy, Austin


    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.

  15. Effects of LiDAR point density, sampling size and height threshold on estimation accuracy of crop biophysical parameters. (United States)

    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.

    Two instances of research facilities responding to public scrutiny will be discussed. The first concerns emissions from a tritium labeling facility operated at Lawrence Berkeley National Laboratory (LBNL); the second deals with releases of plutonium from Lawrence Livermore National Laboratory (LLNL). There are many parallels between these two cases, both of which are still ongoing. In both, the national laboratory is the acknowledged source of low-level (by regulatory standards) radioactive contamination in the community. A major purpose of both investigations is to determine the degree of the contamination and the threat it poses to public health and the environment. The examining panel or committee is similarly constituted in the two cases, including representatives from all four categories of stakeholders: decision makers; scientists and other professionals doing the analysis/assessment; environmental activist or public interest groups; and ordinary citizens (nearly everyone else not in one or more of the first three camps). Both involved community participation from the beginning. The levels of outrage over the events triggering the assessment are comparable; though discovered or appreciated only a few years ago, the release of radiation in both cases occurred or began occurring more than a decade ago. The meetings have been conducted in a similar manner, with comparable frequency, often utilizing the services of professional facilitators. In both cases, the sharply contrasting perceptions of risk commonly seen between scientists and activists were present from the beginning, though the contrast was sharper and more problematical in the Berkeley case. Yet, the Livermore case seems to be progressing towards a satisfactory resolution, while the Berkeley case remains mired in ill-will, with few tangible results after two years of effort. We perceive a wide gap in negotiation skills (at the very least), and a considerable difference in willingness to compromise

    Full Text Available A positioning method based on visible light communication is proposed, which receiving visible light information by low-resolution photodiode array and receiving visual information by the front camera of mobile phone. The terminal position is determined by matching spot information provided by photodiode array with visual information and position information provided by visible light communication. A collinear equation model is derived which based on mobile phone front camera. A hardware-in-loop simulation has been conducted to verify the collinear equation. The three-dimensional positioning error is on the level of decimeter. Moreover, the main factors which affect the positioning accuracy are analyzed in order to further improve the positioning accuracy.

  19. Biophysical Aspects of Radiation Quality. Second Panel Report

    International Nuclear Information System (INIS)


    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

  20. Affective communication in rodents: ultrasonic vocalizations as a tool for research on emotion and motivation. (United States)

    Wöhr, Markus; Schwarting, Rainer K W


    Mice and rats emit and perceive calls in the ultrasonic range, i.e., above the human hearing threshold of about 20 kHz: so-called ultrasonic vocalizations (USV). Juvenile and adult rats emit 22-kHz USV in aversive situations, such as predator exposure and fighting or during drug withdrawal, whereas 50-kHz USV occur in appetitive situations, such as rough-and-tumble play and mating or in response to drugs of abuse, e.g., amphetamine. Aversive 22-kHz USV and appetitive 50-kHz USV serve distinct communicative functions. Whereas 22-kHz USV induce freezing behavior in the receiver, 50-kHz USV lead to social approach behavior. These opposite behavioral responses are paralleled by distinct patterns of brain activation. Freezing behavior in response to 22-kHz USV is paralleled by increased neuronal activity in brain areas regulating fear and anxiety, such as the amygdala and periaqueductal gray, whereas social approach behavior elicited by 50-kHz USV is accompanied by reduced activity levels in the amygdala but enhanced activity in the nucleus accumbens, a brain area implicated in reward processing. These opposing behavioral responses, together with distinct patterns of brain activation, particularly the bidirectional tonic activation or deactivation of the amygdala elicited by 22-kHz and 50-kHz USV, respectively, concur with a wealth of behavioral and neuroimaging studies in humans involving emotionally salient stimuli, such as fearful and happy facial expressions. Affective ultrasonic communication therefore offers a translational tool for studying the neurobiology underlying socio-affective communication. This is particularly relevant for rodent models of neurodevelopmental disorders characterized by social and communication deficits, such as autism and schizophrenia.
