Background Approximately 6% of breast cancers in the United States occur in women under the age of 40 years. Compared with women ≥ 40 years of age, younger women are diagnosed at later stages, have higher rates of recurrence and death, and may be predisposed to secondary breast or ovarian cancer. An informal meeting of experts discussed opportunities for research and public health communication related to breast cancer among young (< 40 and/or premenopausal) women. Methods In September 2011, the Centers for Disease Control and Prevention hosted 18 experts in oncology, genetics, behavioral science, survivorship and advocacy, public health, communication, ethics, nutrition, physical activity, and environmental health. They (1) reviewed research and programmatic knowledge on risk and preventive factors, early detection, and survivorship; and (2) discussed ideas for research, communication, and programmatic efforts related to young women diagnosed with or at risk for early onset breast cancer. Results Levels of evidence and themes for future research regarding risk and preventive factors, including exposures, were discussed. Early detection strategies, including screening, risk assessment, and genetic counseling, as well as survivorship issues, follow-up care, fertility and reproductive health, and psychosocial care were highlighted. Conclusion Community and academic researchers, providers, advocates, and the federal public health community discussed strategies and opportunities for this unique population. Although the evidence is limited, future research and communication activities may be useful to organize future public health initiatives. PMID:23514347

Technology Candidates for Air-to-Air and Air-to-Ground Data Exchange

NASA Technical Reports Server (NTRS)

Haynes, Brian D.

2015-01-01

Technology Candidates for Air-to-Air and Air-to-Ground Data Exchange is a two-year research effort to visualize the U. S. aviation industry at a point 50 years in the future, and to define potential communication solutions to meet those future data exchange needs. The research team, led by XCELAR, was tasked with identifying future National Airspace System (NAS) scenarios, determining requirements and functions (including gaps), investigating technical and business issues for air, ground, & air-to-ground interactions, and reporting on the results. The project was conducted under technical direction from NASA and in collaboration with XCELAR's partner, National Institute of Aerospace, and NASA technical representatives. Parallel efforts were initiated to define the information exchange functional needs of the future NAS, and specific communication link technologies to potentially serve those needs. Those efforts converged with the mapping of each identified future NAS function to potential enabling communication solutions; those solutions were then compared with, and ranked relative to, each other on a technical basis in a structured analysis process. The technical solutions emerging from that process were then assessed from a business case perspective to determine their viability from a real-world adoption and deployment standpoint. The results of that analysis produced a proposed set of future solutions and most promising candidate technologies. Gap analyses were conducted at two points in the process, the first examining technical factors, and the second as part of the business case analysis. In each case, no gaps or unmet needs were identified in applying the solutions evaluated to the requirements identified. The future communication solutions identified in the research comprise both specific link technologies and two enabling technologies that apply to most or all specific links. As a result, the research resulted in a new analysis approach, viewing the underlying architecture of ground-air and air-air communications as a whole, rather than as simple "link to function" paired solutions. For the business case analysis, a number of "reference architectures" were developed for both the future technologies and the current systems, based on three typical configurations of current aircraft. Current and future costs were assigned, and various comparisons made between the current and future architectures. In general, it was assumed that if a future architecture offers lower cost than the current typical architecture, while delivering equivalent or better performance, it is likely that the future solution will gain industry acceptance. Conversely, future architectures presenting higher costs than their current counterparts must present a compelling benefit case in other areas or risk a lack of industry acceptance. The business case analysis consistently indicated lower costs for the proposed future architectures, and in most cases, significantly so. The proposed future solutions were found to offer significantly greater functionality, flexibility, and growth potential over time, at lower cost, than current systems. This was true for overall, fleet-wide equipage for domestic and oceanic air carriers, as well as for single, General Aviation (GA) aircraft. The overall research results indicate that all identified requirements can be met by the proposed solutions with significant capacity for future growth. Results also illustrate that the majority of the future communication needs can be met using currently allocated aviation RF spectrum, if used in more effective ways than it is today. A combination of such optimized aviation-specific links and commercial communication systems meets all identified needs for the 50-year future and beyond, with the caveat that a new, overall function will be needed to manage all information exchange, individual links, security, cost, and other factors. This function was labeled "Delivery Manager" (DM) within this research. DM employs a distributed client/server architecture, for both airborne and ground communications architectures. Final research results included identifying the most promising candidate technologies for the future system, conclusions and recommendations, and identifying areas where further research should be considered.

New challenges in propagation research in the US

NASA Technical Reports Server (NTRS)

Davarian, Faramaz

1993-01-01

Earth/space propagation research in the U.S. is tied to new developments in satellite communications. In spite of the fiber optics competition for trunked point-to-point communications, a host of emerging services are discovering the great potential of satellites for wireless communications. The application of satellites for radio communications appears to grow with a rapid pace in the areas of thin-route and mobile/personal communications. An important factor influencing the future of satellite communications is the congestion of the spectral slots at Ku- and lower bands. This heavy usage of the spectrum gives rise to conflicts among the users and consequently forces regulatory organizations to relocate frequency assignments, a decision that, for obvious reasons, is unpopular with the relocated service. Because of this frequency shortage, frequencies in Ka- and higher spectral bands are currently viewed as good candidates for Earth/space communications in the future. Therefore, new challenges in propagation research in the U.S. include the characterization of mobile/personal links and the investigation of higher bands for satellite communications. The plans and the challenges of the propagation research in the U.S. are briefly reviewed.

Learning in context: identifying gaps in research on the transfer of medical communication skills to the clinical workplace.

2013-02-01

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.

Spinal cord injury (SCI) rehabilitation: systematic analysis of communication from the biopsychosocial perspective.

PubMed

Hartley, Naomi A

2015-07-02

Communication is powerful predictor of health-related quality of life and overall well-being, yet its role in promoting rehabilitation outcomes in spinal cord injury (SCI) is rarely mentioned. This article systematically analyzes and synthesizes literature from multiple disciplines according to a biopsychosocial perspective, providing an evidence base for clinical practice and clear direction for future research. Systematic literature review and analysis, incorporating mapping to International Classification of Functioning, Disability and Health (ICF) codes. In total 4338 entries were retrieved from CINAHL, PsychInfo, Medline, PubMed and SpeechBite databases for the period 1990-2014. A total of 115 treatment and observational studies (quantitative and qualitative) detailed aspects of communication according to structure, function, activity, participation and environmental factors; evident of the complex interactions between communicative function with daily living after SCI. Communication is a relative strength in SCI, key to empowerment, independence, social interaction, and well-being, yet its potential to enhance SCI rehabilitation outcomes remains largely underexplored and untapped. Through elucidating interactions between communication and functioning, the adapted ICF framework affords clinicians and researchers insight into areas of intervention most likely to result in widespread gains. Conscious consideration should be given to the role of communication, within an integrative, strengths-based, multidisciplinary approach to clinical practice and future research. Implications for Rehabilitation Communication fosters empowerment, independence and greater participation in life roles; recognized as a powerful predictor of health-related quality of life and overall well-being. The ICF framework elucidates influences to communicative function, and components which are influenced by communication, providing valuable insight for clinicians and researchers. Therapeutic and research endeavors guided by existing ICF core sets are at risk of failing to consider communication, thereby limiting rehabilitation outcomes. Tapping the potential of communication as a relative strength within SCI rehabilitation holds considerable promise, within integrative, strengths-based, multidisciplinary approaches to clinical practice and future research.

Patient-Clinician Communication About Pain: A Conceptual Model and Narrative Review.

PubMed

Henry, Stephen G; Matthias, Marianne S

2018-02-01

Productive patient-clinician communication is an important component of effective pain management, but we know little about how patients and clinicians actually talk about pain in clinical settings and how it might be improved to produce better patient outcomes. The objective of this review was to create a conceptual model of patient-clinician communication about noncancer pain, review and synthesize empirical research in this area, and identify priorities for future research. A conceptual model was developed that drew on existing pain and health communication research. CINAHL, EMBASE, and PubMed were searched to find studies reporting empirical data on patient-clinician communication about noncancer pain; results were supplemented with manual searches. Studies were categorized and analyzed to identify crosscutting themes and inform model development. The conceptual model comprised the following components: contextual factors, clinical interaction, attitudes and beliefs, and outcomes. Thirty-nine studies met inclusion criteria and were analyzed based on model components. Studies varied widely in quality, methodology, and sample size. Two provisional conclusions were identified: contrary to what is often reported in the literature, discussions about analgesics are most frequently characterized by patient-clinician agreement, and self-presentation during patient-clinician interactions plays an important role in communication about pain and opioids. Published studies on patient-clinician communication about noncancer pain are few and diverse. The conceptual model presented here can help to identify knowledge gaps and guide future research on communication about pain. Investigating the links between communication and pain-related outcomes is an important priority for future research. © 2018 American Academy of Pain Medicine. All rights reserved.

2013-12-01

Over the last six decades, federal investments in scientific research have led to unquestionable economic and societal advances, while expanding human knowledge. Yet, in the current federal fiscal climate, funding for fundamental research is being challenged in some quarters. This situation has created the need for stakeholders in science to step forward and defend the role that basic research plays in creating the knowledge and workforce necessary to address current and future challenges. Communicating to fellow scientists in this environment is necessary but not sufficient to sustaining, or even expanding, support for fundamental research. A multi-faceted approach will be described for enhancing communication to broader audiences, including policy makers and the general public, increasingly responsible for ensuring the future of scientific progress.

2017-09-01

Fifth Generation (5G) is the new evolution of mobile communication technology and will be launched soon in many countries. The researchers and designers of mobile communication technology have been facing the increasing demand of the mobile consumers, high data rates and mobility requirements needed by new wireless applications. Most of the countries have started research on 5G mobile communication technology that is predictable to be launched on 2020 in conjunction with the Olympic Games in Tokyo. Filterbank Multicarrier (FBMC) is one of the modulation techniques for the future 5G mobile communication technology. It uses the multicarrier techniques that are immune to fading caused by transmission of more than one path at a time and also immune to intersymbol interference besides able to function effectively compared to Orthogonal Frequency Division Multiplexing (OFDM) which is used in Fourth Generation (4G) mobile communications technology. This paper discusses the performance of FBMC over OFDM based on the previous journals that were investigated by researchers.

Wilder, Anderson

2015-01-01

There are many concerns with humans living and working in space. These are only compounded by the length of time and distance from Earth that the humans are travelling. For NASA to figure out countermeasures to these problems, they need to be looked at from different directions from a variety of domains. Psychological concerns will be one of the determining factors to whether or not humans will be able to successfully make a journey to Mars or beyond. Communications will be one of the pivotal factors that will affect a crew from a psychological standpoint. During this summer internship, this intern was tasked with looking into delving into this problem. The intern was tasked with performing a literature review on the topic of comparing communications from how they are conducted now to how they will be carried out in the future. These communications have many methods and functions for when and where they happen. A matrix was created to illustrate how these specific communications methods and functions currently are and could be carried out in the future from a time/location perspective. This research will used to help determine what future research will need to focus on in a psychological and technological aspect to better help the crew of a long duration mission.

Future directions in communication research: individual health behaviors and the influence of family communication.

PubMed

Baiocchi-Wagner, Elizabeth A

2015-01-01

Although numerous fields continue to advance research toward various areas of health prevention, communication researchers have yet to examine fully the link between communication and health improvement. This is particularly true of those studying the intersections of family and health communication--unfortunate, given that family members serve as primary socialization agents in health attitudes and behaviors. Using the example of obesity-related health behaviors, the following essay advances the argument that continued research aimed at understanding the intersection of health and families' communicative influence may help to illuminate the nature, causes, and redress to health issues that are correlated with individual health practices. This is accomplished by (a) reviewing contributions and limitations of pioneering studies in (family) health literature and (b) offering three key research areas for health communication exploration that will move scholars toward communication-based solutions (e.g., family-level communication health interventions).

2005-04-01

The purpose of this paper is to examine a cost model of a global ring satellite communications system as a 2G-satellite (second generation Internet satellite) for the future Internet satellite, whose capacity is around 120 Gbps. The authors proposed the future needs of research and development of communications satellite for the next 30 years and also proposed the approach of three generations for the future Internet satellites. First, the paper reviews and updates the original proposal for the future needs of communications satellite, considering the recent development of the quantum communication technology. It also examines the communications satellite applicability for bridging the digital divide in the Asia-Oceania as an example. The paper clarifies this possibility of communications satellite by showing various relationships among Internet penetration, land area, population growth, etc. Second, the cost of the global ring satellite is examined. The user terminal is considered as a combination of an earth terminal and wireless local area network for a user community. This paper shows that the global ring satellite has a possibility of a good cost-competitiveness to the terrestrial system because of the global communications system can be configured only by satellite system.

Communications systems have always been a critical element in aviation. Until recently, nearly all communications between the ground and aircraft have been based on analog voice technology. But the future of global aviation requires a more sophisticated "information infrastructure" which not only provides more and better communications, but integrates the key information functions (communications, navigation, and surveillance) into a modern, network-based infrastructure. Satellite communications will play an increasing role in providing information infrastructure solutions for aviation. Developing and adapting satellite communications technologies for aviation use is now receiving increased attention as the urgency to develop information infrastructure solutions grows. The NASA Glenn Research Center is actively involved in research and development activities for aeronautical satellite communications, with a key emphasis on air traffic management communications needs. This paper describes the recent results and status of NASA Glenn's research program.

1993-01-01

Early in the 21st century, the demand for personal communications using mobile, hand-held, and VSAT terminals will rapidly increase. In a future system, many different types of services should be provided with one-hop connection. The Communications Research Laboratory (CRL) has studied a future advanced mobile satellite communications system using millimeter wave and Ka band. In 1990, CRL started the Communications and Broadcasting Engineering Test Satellite (COMETS) project. The satellite has been developed in conjunction with NASDA and will be launched in 1997. This paper describes the COMETS payload configuration and the experimental system for the advanced mobile communications mission.

Therapeutic communication training in long-term care institutions: recommendations for future research.

Levy-Storms, Lené

2008-10-01

The purpose of this review is to critique contemporary experimental research and to recommend future directions for research interventions on nursing aides' therapeutic communication with older adults who have cognitive impairment and/or dementia in institutional long-term care settings. This literature review covers 13 journal articles (1999-2006) and focuses on the strengths and weaknesses of experimental research interventions to improve nursing aides' therapeutic communication with older adults who have cognitive impairment and/or dementia in long-term care settings. Based on this review, recommendations for improved experimental designs include a minimum of two groups with one being a control and randomization of subjects at the care unit level, an average 3-5h of total training, a minimum of a 6-month total evaluation period, and objective outcomes relevant to both nursing aides and residents. Findings from studies in this review indicate that the following therapeutic communication techniques can be taught and can benefit staffs and older adults' quality of life: verbal and non-verbal communication behaviors including open-ended questions, positive statements, eye contact, affective touch, and smiling. Some evidence exists to support that nursing aides can improve their therapeutic communication during care. Nursing aides need not only more training in therapeutic communication but also ongoing, dedicated supervision in psychosocial aspects of care.

In science communication, why does the idea of the public deficit always return? Exploring key influences.

PubMed

Suldovsky, Brianne

2016-05-01

Despite mounting criticism, the deficit model remains an integral part of science communication research and practice. In this article, I advance three key factors that contribute to the idea of the public deficit in science communication, including the purpose of science communication, how communication processes and outcomes are conceptualized, and how science and scientific knowledge are defined. Affording science absolute epistemic privilege, I argue, is the most compelling factor contributing to the continued use of the deficit model. In addition, I contend that the deficit model plays a necessary, though not sufficient, role in science communication research and practice. Areas for future research are discussed. © The Author(s) 2016.

Factors associated with communication-based sedentary behaviors among youth: are talking on the phone, texting, and instant messaging new sedentary behaviors to be concerned about?

PubMed

Leatherdale, Scott T

2010-09-01

Sedentary behavior research typically only examines screen time activities and not communication time activities, such as talking on the phone, texting, or instant messaging. Data from 2,449 grade 5 to 8 students were used to examine factors associated with the time youth spent in communication-based sedentary behaviors. Screen time, physical activity, grade, and gender were associated with moderate and high communication time. Future research on sedentary behavior should include measures of communication time.

Microbiologists’ Public Engagement Views and Behaviors †

PubMed Central

Besley, John; Kahlor, Lee Ann; Koh, Hyeseung; Copple, Jacob; Yuan, Shupei

2018-01-01

In this study, we present results from an extensive survey of US-based microbiologists (adults) to explore these scientists’ perceptions and behaviors related to communicating their research. Specifically, we explored the frequency with which microbiologists engage in public communication, how they evaluate their public communication experiences, and the factors associated with their willingness to engage in face-to-face and online public communication in the future. Data from a multi-wave online survey suggest that microbiologists (N = 903) are somewhat frequent communicators who derive great value from their outreach efforts. The results further suggest that social and psychological drivers of future intentions to engage with the public are consistent with the Theory of Planned Behavior (TPB). Specifically, microbiologists with more positive attitudes toward engagement were more willing to partake in direct and online communication activities. Similarly, microbiologists who believe they possess communication skills are more willing than their less efficacious colleagues to do either type of outreach. Our results also indicate that more-senior and more-active researchers are more willing to participate in direct and online engagement. Implications for communication training are discussed.

This paper introduces the composition and working principle of retro-reflecting modulation optical communication system, analyzes the link budget of this system, reviews the types of optical system and optical modulator, summarizes this technology future research direction and application prospects.

Cultural differences in medical communication: a review of the literature.

PubMed

Schouten, Barbara C; Meeuwesen, Ludwien

2006-12-01

Culture and ethnicity have often been cited as barriers in establishing an effective and satisfying doctor-patient relationship. The aim of this paper is to gain more insight in intercultural medical communication difficulties by reviewing observational studies on intercultural doctor-patient communication. In addition, a research model for studying this topic in future research is proposed. A literature review using online databases (Pubmed, Psychlit) was performed. Findings reveal major differences in doctor-patient communication as a consequence of patients' ethnic backgrounds. Doctors behave less affectively when interacting with ethnic minority patients compared to White patients. Ethnic minority patients themselves are also less verbally expressive; they seem to be less assertive and affective during the medical encounter than White patients. Most reviewed studies did not relate communication behaviour to possible antecedent culture-related variables, nor did they assess the effect of cultural variations in doctor-patient communication on outcomes, leaving us in the dark about reasons for and consequences of differences in intercultural medical communication. Five key predictors of culture-related communication problems are identified in the literature: (1) cultural differences in explanatory models of health and illness; (2) differences in cultural values; (3) cultural differences in patients' preferences for doctor-patient relationships; (4) racism/perceptual biases; (5) linguistic barriers. It is concluded that by incorporating these variables into a research model future research on this topic can be enhanced, both from a theoretical and a methodological perspective. Using a cultural sensitive approach in medical communication is recommended.

Strengthening the quality of longitudinal research into cognitive-communication recovery after traumatic brain injury: A systematic review.

PubMed

Elbourn, Elise; Togher, Leanne; Kenny, Belinda; Power, Emma

2017-02-01

(i) To systematically review longitudinal and prognostic studies relating to the trajectory of cognitive-communication recovery after TBI and (ii) to provide recommendations to strengthen future research. Thirteen health literature databases were accessed up until July 2014. Articles were screened systematically against pre-determined inclusion and exclusion criteria. Quality reviews were performed on the selected articles using a modified Downs & Black Rating Scale. Two independent reviewers performed the reviews. Sixteen longitudinal and prognostic articles met the inclusion criteria. There was evidence of either maintenance or improvement of cognitive-communication skills during the first 3 years post-injury. However, the studies did not provide detailed recovery trajectories, by failing to evaluate numerous data points over time. No studies evaluated recovery beyond 3 years post-injury. Injury severity, lesion location, brain volume loss and conversation skills may predict specific cognitive-communication outcomes. There was high variability in study characteristics and measures. There is currently scarce evidence regarding cognitive-communication recovery and prognosis. People with TBI may recover or maintain pre-morbid cognitive-communication skills during the early rehabilitation stage. Further research detailing the recovery trajectory with a view to evaluating predictive factors is strongly indicated. Guidelines for future research are provided.

Cappella, Joseph N

2017-10-01

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

2012-01-01

Since CAMbrella is a networking project funded by the European Commission explicitly to build and sustain a complementary and alternative medicine (CAM) research network in Europe, communication and dissemination play a large role and form a work package of their own. The present article gives an outline of the communication and dissemination work in the CAMbrella consortium. The intensive building of sound internal communication is an essential part in establishing a functioning structure for collaboration in a diverse group of 16 partner institutions from 12 countries, as exists in the CAMbrella project. The means and tools for dissemination of results to the scientific community and the European public at large, as well as to the European policy makers, are presented. The development of the corporate design and a dissemination strategy are described in detail. In addition, some basic information regarding previous CAM research efforts, which might be interesting for future consortium building in the field of CAM research, is given. Internal communication within a heterogeneous research group, the maintenance of a work-oriented style of communication and a consensus oriented effort in establishing dissemination tools and products will be essential for any future consortium in the CAM field. The outlook shows the necessity for active political encouragement of CAM research and the desideratum of a Pan-European institution analogous to the NIH (National Institutes of Health) in the USA.

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

PubMed

Howes, Loene M

2015-03-01

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

This document is being provided as part of ITT s NASA Glenn Research Center Aerospace Communication Systems Technical Support (ACSTS) contract NNC05CA85C, Task 7: New ATM Requirements-Future Communications, C-band and L-band Communications Standard Development. Task 7 was motivated by the five year technology assessment performed for the Federal Aviation Administration (FAA) under the joint FAA-EUROCONTROL cooperative research Action Plan (AP-17), also known as the Future Communications Study (FCS). It was based on direction provided by the FAA project-level agreement (PLA FY09_G1M.02-02v1) for "New ATM Requirements-Future Communications." Task 7 was separated into two distinct subtasks, each aligned with specific work elements and deliverable items. Subtask 7-1 addressed C-band airport surface data communications standards development, systems engineering, test bed development, and tests/demonstrations to establish operational capability for what is now referred to as the Aeronautical Mobile Airport Communications System (AeroMACS). Subtask 7-2, which is the subject of this report, focused on preliminary systems engineering and support of joint FAA/EUROCONTROL development and evaluation of a future L-band (960 to 1164 MHz) air/ground (A/G) communication system known as the L-band digital aeronautical communications system (L-DACS), which was defined during the FCS. The proposed L-DACS will be capable of providing ATM services in continental airspace in the 2020+ timeframe. Subtask 7-2 was performed in two phases. Phase I featured development of Concepts of Use, high level functional analyses, performance of initial L-band system safety and security risk assessments, and development of high level requirements and architectures. It also included the aforementioned support of joint L-DACS development and evaluation, including inputs to L-DACS design specifications. Phase II provided a refinement of the systems engineering activities performed during Phase I, along with continued joint FAA/EUROCONTROL L-DACS development and evaluation support.

Online communication among patients and consumers through support groups, discussion boards, and knowledge resources is becoming more common. In this paper, we discuss key methods through which such web-based peer-to-peer communication may affect health promotion and disease prevention behavior (exchanges of information, emotional and instrumental support, and establishment of group norms and models). We also discuss several theoretical models for studying online peer communication, including social theory, health communication models, and health behavior models. Although online peer communication about health and disease is very common, research evaluating effects on health behaviors, mediators, and outcomes is still relatively sparse. We suggest that future research in this field should include formative evaluation and studies of effects on mediators of behavior change, behaviors, and outcomes. It will also be important to examine spontaneously emerging peer communication efforts to see how they can be integrated with theory-based efforts initiated by researchers. PMID:19449267

Objectives Perceived credibility of a message’s source can affect persuasion. This paper reviews how beliefs about the source of tobacco control messages may encourage attitude and behavior change. Methods We conducted a series of searches of the peer-reviewed literature using terms from communication and public health fields. We reviewed research on source credibility, its underlying concepts, and its relation to the persuasiveness of tobacco control messages. Results We recommend an agenda for future research to bridge the gaps between communication literature on source credibility and tobacco control research. Our recommendations are to study the impact of source credibility on persuasion with long-term behavior change outcomes, in different populations and demographic groups, by developing new credibility measures that are topic- and organization-specific, by measuring how credibility operates across media platforms, and by identifying factors that enhance credibility and persuasion. Conclusions This manuscript reviews the state of research on source credibility and identifies gaps that are maximally relevant to tobacco control communication. Knowing first whether a source is perceived as credible, and second, how to enhance perceived credibility, can inform the development of future tobacco control campaigns and regulatory communications.

Theory and research suggest that vocal development predicts “useful speech” in preschoolers with autism spectrum disorder (ASD), but conventional methods for measurement of vocal development are costly and time consuming. This longitudinal correlational study examines the reliability and validity of several automated indices of vocalization development relative to an index derived from human coded, conventional communication samples in a sample of preverbal preschoolers with ASD. Automated indices of vocal development were derived using software that is presently “in development” and/or only available for research purposes and using commercially available Language ENvironment Analysis (LENA) software. Indices of vocal development that could be derived using the software available for research purposes: (a) were highly stable with a single day-long audio recording, (b) predicted future spoken vocabulary to a degree that was nonsignificantly different from the index derived from conventional communication samples, and (c) continued to predict future spoken vocabulary even after controlling for concurrent vocabulary in our sample. The score derived from standard LENA software was similarly stable, but was not significantly correlated with future spoken vocabulary. Findings suggest that automated vocal analysis is a valid and reliable alternative to time intensive and expensive conventional communication samples for measurement of vocal development of preverbal preschoolers with ASD in research and clinical practice.

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

NASA Technical Reports Server (NTRS)

Kerczewski, Robert J.

2002-01-01

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

The aim of this paper is to describe educational programs that reportedly teach how to break bad news in the emergency department. We also suggest some recommendations on how to communicate bad news based on the research of evidence available in the field. The examined evidence points toward six major components with which physicians should familiarize when communicating bad news: 1) doctor-patient empathic communication, 2) establishing a proper space to give the news, 3) identifying characteristics of the person who receives the news, 4) essential aspects for communicating the news; 5) emotional support, and 6) medical and administrative aspects of the encounter. Finally, we point out several limitations in the studies in the field and future challenges identified in the communication of bad news in emergency room facilities.

Despite the high burden and poor rates of treatment associated with mental illness and substance use disorders, public support for allocating resources to improving treatment for these disorders is low. A growing body of research suggests that effective policy communication strategies can increase public support for policies benefiting people with these conditions. In October 2015, the Center for Mental Health and Addiction Policy Research at Johns Hopkins University convened an expert forum to identify what is currently known about the effectiveness of such policy communication strategies and produce recommendations for future research. One of the key conclusions of the forum was that communication strategies using personal narratives to engage audiences have the potential to increase public support for policies benefiting persons with mental illness or substance use disorders. Specifically, narratives combining personal stories with depictions of structural barriers to mental illness and substance use disorder treatment can increase the public's willingness to invest in the treatment system. Depictions of mental illness and violence significantly increase public stigma toward people with mental illness and are no more effective in increasing willingness to invest in mental health services than nonstigmatizing messages about structural barriers to treatment. Future research should prioritize development and evaluation of communication strategies to increase public support for evidence-based substance use disorder policies, including harm reduction policies-such as needle exchange programs-and policies expanding treatment.

NASA's Aeronautics Research Mission Directorate (ARMD) has recently solicited proposals and awarded funds for research and development to achieve and exceed the goals envisioned in the ARMD Strategic Implementation Plan (SIP). The Hyper-Spectral Communications and Networking for Air Traffic Management (ATM) (HSCNA) project is the only University Leadership Initiative (ULI) program to address communications and networking (and to a degree, navigation and surveillance). This paper will provide an overview of the HSCNA project, and specifically describe two of the project's technical challenges: comprehensive aviation communications and networking assessment, and proposed multi-band and multimode communications and networking. The primary goals will be described, as will be research and development aimed to achieve and exceed these goals. Some example initial results are also provided.

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.

Advanced Communication Processing Techniques

Scholtz, Robert A.

This document contains the proceedings of the workshop Advanced Communication Processing Techniques, held May 14 to 17, 1989, near Ruidoso, New Mexico. Sponsored by the Army Research Office (under Contract DAAL03-89-G-0016) and organized by the Communication Sciences Institute of the University of Southern California, the workshop had as its objective to determine those applications of intelligent/adaptive communication signal processing that have been realized and to define areas of future research. We at the Communication Sciences Institute believe that there are two emerging areas which deserve considerably more study in the near future: (1) Modulation characterization, i.e., the automation of modulation format recognition so that a receiver can reliably demodulate a signal without using a priori information concerning the signal's structure, and (2) the incorporation of adaptive coding into communication links and networks. (Encoders and decoders which can operate with a wide variety of codes exist, but the way to utilize and control them in links and networks is an issue). To support these two new interest areas, one must have both a knowledge of (3) the kinds of channels and environments in which the systems must operate, and of (4) the latest adaptive equalization techniques which might be employed in these efforts.

The Internet and science communication: blurring the boundaries

Warden, R

2010-01-01

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

Although storytelling often has negative connotations within science, narrative formats of communication should not be disregarded when communicating science to nonexpert audiences. Narratives offer increased comprehension, interest, and engagement. Nonexperts get most of their science information from mass media content, which is itself already biased toward narrative formats. Narratives are also intrinsically persuasive, which offers science communicators tactics for persuading otherwise resistant audiences, although such use also raises ethical considerations. Future intersections of narrative research with ongoing discussions in science communication are introduced.

To address emerging saturation in the VHF aeronautical bands allocated internationally for air traffic management communications, the International Civil Aviation Organization (ICAO) has requested development of a common global solution through its Aeronautical Communications Panel (ACP). In response, the Federal Aviation Administration (FAA) and Eurocontrol initiated a joint study, with the support of NASA and U.S. and European contractors, to provide major findings on alternatives and recommendations to the ICAO ACP Working Group C (WG-C). Under an FAA/Eurocontrol cooperative research and development agreement, ACP WG-C Action Plan 17 (AP-17), commonly referred to as the Future Communications Study (FCS), NASA Glenn Research Center is responsible for the investigation of potential communications technologies that support the long-term mobile communication operational concepts of the FCS. This report documents the results of the first phase of the technology assessment and recommendations referred to in the Technology Pre-Screening Task 3.1 of AP-17. The prescreening identifies potential technologies that are under development in the industry and provides an initial assessment against a harmonized set of evaluation criteria that address high level capabilities, projected maturity for the time frame for usage in aviation, and potential applicability to aviation. A wide variety of candidate technologies were evaluated from several communications service categories including: cellular telephony; IEEE-802.xx standards; public safety radio; satellite and over-the-horizon communications; custom narrowband VHF; custom wideband; and military communications.

The project A90KM616, Orientatie SATCOM, is being performed on behalf of the Royal Netherlands Navy (RNLN) to assist the Navy on the subject of satellite communications. An overview is given of the phenomenon satellite communication. The result is a general overview of satellite communications for both civil and military applications. Some examples of applications are; international telephony, television broadcasting, small private business networks, and mobile (at the moment still principally maritime) communications. In these applications satellite communication systems provide a global coverage and a high flexibility. The scientific articles have not been considered because in this stage it was the intention to study on a specialist level the broad area of techniques. Magazines, books, and a number of reports of universities and research institutes have been the main sources of information. They provided afforded an understanding of the existing systems and insight in the future developments.

Theory and research suggest that vocal development predicts "useful speech" in preschoolers with autism spectrum disorder (ASD), but conventional methods for measurement of vocal development are costly and time consuming. This longitudinal correlational study examines the reliability and validity of several automated indices of vocalization development relative to an index derived from human coded, conventional communication samples in a sample of preverbal preschoolers with ASD. Automated indices of vocal development were derived using software that is presently "in development" and/or only available for research purposes and using commercially available Language ENvironment Analysis (LENA) software. Indices of vocal development that could be derived using the software available for research purposes: (a) were highly stable with a single day-long audio recording, (b) predicted future spoken vocabulary to a degree that was nonsignificantly different from the index derived from conventional communication samples, and (c) continued to predict future spoken vocabulary even after controlling for concurrent vocabulary in our sample. The score derived from standard LENA software was similarly stable, but was not significantly correlated with future spoken vocabulary. Findings suggest that automated vocal analysis is a valid and reliable alternative to time intensive and expensive conventional communication samples for measurement of vocal development of preverbal preschoolers with ASD in research and clinical practice.

2018-01-01

Device-to-Device (D2D) communications has been realized as an effective means to improve network throughput, reduce transmission latency, and extend cellular coverage in 5G systems. Network coding is a well-established technique known for its capability to reduce the number of retransmissions. In this article, we review state-of-the-art network coding in relay-based D2D communications, in terms of application scenarios and network coding techniques. We then apply two representative network coding techniques to dual-hop D2D communications and present an efficient relay node selecting mechanism as a case study. We also outline potential future research directions, according to the current research challenges. Our intention is to provide researchers and practitioners with a comprehensive overview of the current research status in this area and hope that this article may motivate more researchers to participate in developing network coding techniques for different relay-based D2D communications scenarios.

For human and robotic exploration missions in the Vision for Exploration, roadmaps are needed for capability development and investments based on advanced technology developments. A roadmap development process was undertaken for the needed communications, and networking capabilities and technologies for the future human and robotics missions. The underlying processes are derived from work carried out during development of the future space communications architecture, an d NASA's Space Architect Office (SAO) defined formats and structures for accumulating data. Interrelationships were established among emerging requirements, the capability analysis and technology status, and performance data. After developing an architectural communications and networking framework structured around the assumed needs for human and robotic exploration, in the vicinity of Earth, Moon, along the path to Mars, and in the vicinity of Mars, information was gathered from expert participants. This information was used to identify the capabilities expected from the new infrastructure and the technological gaps in the way of obtaining them. We define realistic, long-term space communication architectures based on emerging needs and translate the needs into interfaces, functions, and computer processing that will be required. In developing our roadmapping process, we defined requirements for achieving end-to-end activities that will be carried out by future NASA human and robotic missions. This paper describes: 10 the architectural framework developed for analysis; 2) our approach to gathering and analyzing data from NASA, industry, and academia; 3) an outline of the technology research to be done, including milestones for technology research and demonstrations with timelines; and 4) the technology roadmaps themselves.

It is estimated that around 50-90% of people with learning disabilities experience difficulties in communicating. Previous research has linked communication difficulties and self-esteem in other populations, yet this relationship has not previously been investigated for people with Down syndrome. To explore the relationship between communication and self-esteem in adults with Down syndrome. This research also aimed to offer an empowering and inclusive opportunity for adults with learning disabilities to be involved in research. Recruitment took place via a charity established for people with Down syndrome. Twelve adults with Down syndrome and an adult they nominated were approached. A qualitative methodology was selected to explore communication and self-esteem. A thematic analysis focused on the qualitative data collected via semi-structured interviews. Major themes within the data revealed that a relationship between communication and self-esteem may exist for adults with Down syndrome. This study demonstrated that people with Down syndrome may experience low self-esteem that may be linked to communication. The clinical implications of this are considered and areas for future research are identified. © 2014 Royal College of Speech and Language Therapists.

Malaria is a major public health problem; about half of the world's populations live under exposure. The problem is increasing in magnitude and complexity because it is entwined with low socio-economic status, which makes African women and children particularly vulnerable. Combating malaria therefore requires concerted international efforts with an emphasis on Africa. The Multilateral Initiative on Malaria (MIM) was founded in 1997 to meet that need through strengthening research capacity in Africa, increasing international cooperation and communication, and utilization of research findings to inform malaria prevention, treatment, and control. The review undertaken in 2002 showed that through improved communication and science-focused institutional networks, MIM had brought African scientists together, opened up communication among malaria stakeholders, and provided Internet access to literature. The achievements were made through four autonomous constituents including the coordinating Secretariat being hosted for the first time in Africa by the African Malaria Network Trust (AMANET) for the period 2006-2010. The other constituents are the MIM TDR providing funding for peer-reviewed research; MIMCom facilitating Internet connectivity, access to medical literature, and communication between scientists inside and outside of Africa; and MR4 providing scientists access to research tools, standardized reagents, and protocols. Future plans will mostly consolidate the gains made under the MIM Strategic Plan for the period 2003-2005.

Publication on paper of research results following peer-review and editing has been the accepted means of scientific communication for several centuries. Today, the continued growth in the volume of scientific literature, the increased unit costs of archiving paper publications, and the rapidly increasing power and availability of electronic technology are creating tremendous pressures on traditional scientific communication. The earth sciences are not immune from these pressures, and the role of the traditional publication as the primary means of communication is rapidly changing. Electronic publications and network technology are radically altering the relationship between interpretative result and the underlying data. Earth science research institutions, including the Kansas Geological Survey, are experimenting with new forms of on-line publication that assure broad access to research and data and improve application of research results to societal problems.

Molecular communication and networking: opportunities and challenges.

The ability of engineered biological nanomachines to communicate with biological systems at the molecular level is anticipated to enable future applications such as monitoring the condition of a human body, regenerating biological tissues and organs, and interfacing artificial devices with neural systems. From the viewpoint of communication theory and engineering, molecular communication is proposed as a new paradigm for engineered biological nanomachines to communicate with the natural biological nanomachines which form a biological system. Distinct from the current telecommunication paradigm, molecular communication uses molecules as the carriers of information; sender biological nanomachines encode information on molecules and release the molecules in the environment, the molecules then propagate in the environment to receiver biological nanomachines, and the receiver biological nanomachines biochemically react with the molecules to decode information. Current molecular communication research is limited to small-scale networks of several biological nanomachines. Key challenges to bridge the gap between current research and practical applications include developing robust and scalable techniques to create a functional network from a large number of biological nanomachines. Developing networking mechanisms and communication protocols is anticipated to introduce new avenues into integrating engineered and natural biological nanomachines into a single networked system. In this paper, we present the state-of-the-art in the area of molecular communication by discussing its architecture, features, applications, design, engineering, and physical modeling. We then discuss challenges and opportunities in developing networking mechanisms and communication protocols to create a network from a large number of bio-nanomachines for future applications.

Hyper-Spectral Networking Concept of Operations and Future Air Traffic Management Simulations

The NASA sponsored Hyper-Spectral Communications and Networking for Air Traffic Management (ATM) (HSCNA) project is conducting research to improve the operational efficiency of the future National Airspace System (NAS) through diverse and secure multi-band, multi-mode, and millimeter-wave (mmWave) wireless links. Worldwide growth of air transportation and the coming of unmanned aircraft systems (UAS) will increase air traffic density and complexity. Safe coordination of aircraft will require more capable technologies for communications, navigation, and surveillance (CNS). The HSCNA project will provide a foundation for technology and operational concepts to accommodate a significantly greater number of networked aircraft. This paper describes two of the HSCNA projects technical challenges. The first technical challenge is to develop a multi-band networking concept of operations (ConOps) for use in multiple phases of flight and all communication link types. This ConOps will integrate the advanced technologies explored by the HSCNA project and future operational concepts into a harmonized vision of future NAS communications and networking. The second technical challenge discussed is to conduct simulations of future ATM operations using multi-bandmulti-mode networking and technologies. Large-scale simulations will assess the impact, compared to todays system, of the new and integrated networks and technologies under future air traffic demand.

Williams, Christine L; Parker, Carlo

2012-04-01

There have been few reported studies of communication between spouses with Alzheimer's disease (AD) and related dementia. An observer rating scale for verbal and nonverbal behavior, Verbal-Nonverbal Interaction Scale for Caregivers (VNVIS-CG), was developed to study caregiver communication in couples affected by AD. Preliminary psychometric testing showed that the VNVIS-CG evidenced good reliability and validity. Researchers observed both common caregiver communication strategies and novel strategies that have not been reported in the literature. In future studies, researchers can examine the relationship between caregiver communication and indicators of mental health. Everyday conversations provide fertile ground for nurses to influence family relationships. Nurses can teach caregivers to use strategies that promote engagement and avoid those that discourage participation.

How to succeed in facilitating for empowering processes within social work practice is a central topic in both theoretical discussions and regarding its principles in practice. With a particular focus on how dialogical communication can play a part in order to practice empowering social work, through this text the author frames HUSK as a project facilitating the underpinning humanistic approaches in social work. Dialogical communication and its philosophical base is presented and recognized as a means to achieve empowering social work as well as highlighting the importance of the humanistic approach. The author also underscores how HUSK projects in themselves were enabled because of the required collaboration between service users, professionals, and researchers that signified HUSK. This is pinpointed as having potential for a future research agenda as well as pointing at how the outcomes of the projects may impact future social work practice when the goal is to conduct empowering social work.

2016-04-01

A worldwide growing interest in fast and secure data communications pushes technology development along two lines. While fast communications can be realized using laser communications in fiber and free-space, inherently secure communications can be achieved using quantum key distribution (QKD). By combining both technologies in a single device, many synergies can be exploited, therefore reducing size, weight and power of future systems. In recent experiments we demonstrated quantum communications over large distances as well as between an aircraft and a ground station which proved the feasibility of QKD between moving partners. Satellites thus may be used as trusted nodes in combination with QKD receiver stations on ground, thereby enabling fast and secure communications on a global scale. We discuss the previous experiment with emphasis on necessary developments to be done and corresponding ongoing research work of German Aerospace Center (DLR) and Ludwig Maximilians University Munich (LMU). DLR is performing research on satellite and ground terminals for the high-rate laser communication component, which are enabling technologies for the QKD link. We describe the concept and hardware of three generations of OSIRIS (Optical High Speed Infrared Link System) laser communication terminals for low Earth orbiting satellites. The first type applies laser beam pointing solely based on classical satellite control, the second uses an optical feedback to the satellite bus and the third, currently being in design phase, comprises of a special coarse pointing assembly to control beam direction independent of satellite orientation. Ongoing work also targets optical terminals for CubeSats. A further increase of beam pointing accuracy can be achieved with a fine pointing assembly. Two ground stations will be available for future testing, an advanced stationary ground station and a transportable ground station. In parallel the LMU QKD source size will be reduced by more than an order of magnitude thereby simplifying its integration into future free-space optical communication links with CubeSats.

A separate report to be published by NASA/CR-2008-215144, entitled Final Report on Technology Investigations for Provision of Future Aeronautical Communications will include an assessment of all five final candidate technologies considered by the U.S. agencies (FAA and NASA) and EUROCONTROL. It will also provide an overview of the entire technology assessment process, including final recommendations. All three phases of this work were performed in compliance with the Terms of Reference for the Action Plan number 17 (AP-17) cooperative research agreement among EUROCONTROL, FAA, and NASA along with the general guidance of the FAA and EUROCONTROL available throughout this study.

On the Communicative Function of Body Odors.

PubMed

de Groot, Jasper H B; Semin, Gün R; Smeets, Monique A M

2017-03-01

Humans use multiple senses to navigate the social world, and the sense of smell is arguably the most underestimated one. An intriguing aspect of the sense of smell is its social communicative function. Research has shown that human odors convey information about a range of states (e.g., emotions, sickness) and traits (e.g., individuality, gender). Yet, what underlies the communicability of these states and traits via smell? We fill this explanatory gap with a framework that highlights the dynamic and flexible aspects of human olfactory communication. In particular, we explain how chemical profiles, associative learning (i.e., the systematic co-occurrence of chemical profiles with state- or trait-related information), and top-down contextual influences could interact to shape human odor perception. Our model not only helps to integrate past research on human olfactory communication but it also opens new avenues for future research on this fascinating, yet to date poorly understood, field.

Quantum Physics Principles and Communication in the Acute Healthcare Setting: A Pilot Study.

PubMed

Helgeson, Heidi L; Peyerl, Colleen Kraft; Solheim-Witt, Marit

This pilot study explores whether clinician awareness of quantum physics principles could facilitate open communication between patients and providers. In the spirit of action research, this study was conceptualized with a holistic view of human health, using a mixed method design of grounded theory as an emergent method. Instrumentation includes surveys and a focus group discussion with twelve registered nurses working in an acute care hospital setting. Findings document that the preliminary core phenomenon, energy as information, influences communication in the healthcare environment. Key emergent themes include awareness, language, validation, open communication, strategies, coherence, incoherence and power. Research participants indicate that quantum physics principles provide a language and conceptual framework for improving their awareness of communication and interactions in the healthcare environment. Implications of this pilot study support the feasibility of future research and education on awareness of quantum physics principles in other clinical settings. Copyright © 2016 Elsevier Inc.

This study aims to understand the process of shaping communication competence. Participants were pre-service teachers in the primary school education teacher who conducted teaching program internship program. Observations and interviews found that culture, experience, and education were the components that developed the communication competence within the instructional context. The former two components dominantly shape communication instructional competencies, whereas the latter contributes insignificantly. Education emphasizes on teacher’s pedagogy and professional competences. In the future, educational institutions for pre-service teachers could use this research results to Determine the process of developing communication competence.

False alarms, real challenges--one university's communication response to the 2001 anthrax crisis.

PubMed

Clarke, Christopher E; Chess, Caron

2006-01-01

Considerable research exists on how government agencies at the federal, state, and local levels communicated during the fall 2001 anthrax attacks. However, there is little research on how other institutions handled this crisis, in terms of their response to potential anthrax contamination (aka "white powder scares") and their approach to disseminating important health and safety information. In this article, we investigate a major university's communication response to the anthrax crisis. First, we describe its communication experiences relating to a large white powder scare that occurred in October 2001. Second, we describe the university's broader communication efforts in terms of several important elements of risk communication research, including influence of source attributes, key messages, preferred channels, responses to information requests, and organizational influences. This study underlines that an institution does not have to be directly affected by a crisis to find itself on the communication "front lines." Moreover, other institutions may find it useful to learn from the experiences of this university, so that they may communicate more effectively during future crises.

Teaching topography-based and selection-based verbal behavior to developmentally disabled individuals: Some considerations

PubMed Central

Shafer, Esther

1993-01-01

Augmentative and alternative communication systems are widely recommended for nonvocal developmentally disabled individuals, with selection-based systems becoming increasingly popular. However, theoretical and experimental evidence suggests that topography-based communication systems are easier to learn. This paper discusses research relevant to the ease of acquisition of topography-based and selection-based systems. Additionally, current practices for choosing and designing communication systems are reviewed in order to investigate the extent to which links have been made with available theoretical and experimental knowledge. A stimulus equivalence model is proposed as a clearer direction for practitioners to follow when planning a communication training program. Suggestions for future research are also offered.

1997-01-01

Publication on paper of research results following peer-review and editing has been the accepted means of scientific communication for several centuries. Today, the continued growth in the volume of scientific literature, the increased unit costs of archiving paper publications, and the rapidly increasing power and availability of electronic technology are creating tremendous pressures on traditional scientific communication. The earth sciences are not immune from these pressures, and the role of the traditional publication as the primary means of communication is rapidly changing. Electronic publications and network technology are radically altering the relationship between interpretative result and the underlying data. Earth science research institutions, including the Kansas Geological Survey, are experimenting with new forms of on-line publication that assure broad access to research and data and improve application of research results to societal problems. ?? 1997 Elsevier Science Ltd.

Newborn screening for metabolic disorders: parental perceptions of the initial communication of results.

PubMed

Buchbinder, Mara; Timmermans, Stefan

2012-08-01

Positive newborn screening (NBS) results cause significant parental distress, but little is known about how parents find out about children's screening results and what they are told. This qualitative, exploratory study reports on parents' perceptions of the initial communication of NBS results. Participants included the parents of 75 infants referred to a metabolic clinic in California over a 3-year period (2007-2010). Parents provided information about the initial communication of NBS results during audiotaped clinical encounters and open-ended interviews. Transcripts were analyzed inductively using thematic coding. Responses fell into 3 primary themes: sources of news delivery, providing information, and mitigation strategies. The findings suggest that health care providers have access to a range of communicative resources to buffer the impact of positive screening results that may be mobilized in future interventions. Recommendations for improving the communication process and future research directions are discussed.

Miranda, Felix A.

2015-01-01

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.

Revisiting Communicative Competence in Augmentative and Alternative Communication.

PubMed

Tsai, Meng-Ju

2016-01-01

This tutorial paper is to explore the novel nature of communicative competence in augmentative and alternative communication (AAC) practice by comparing it to communicative competence in naturally verbal dyadic communication. This paper first reviews the four domains of communicative competence in AAC practice. Second, it examines competence in dyadic communications between naturally verbal people without disabilities, deriving new insights and using these to analyze the evolution of communicative competence in AAC practice. Communicative competence in AAC practice should be reconceptualized from a new perspective as dyadic, learned, co-constructed, and of relative value, ascertained through performance. In the past decades, the study of communicative competence in AAC practice has primarily focused on individual persons who use AAC. However, the conceptualization of communicative competence should shift away from an individualized construct toward a dyadic construct. This leads to a discussion of potential implications and future research directions. This paper might offer AAC researchers and practitioners an opportunity to deepen their understanding of communicative competence and promote more positive outcomes for people who use AAC. © 2017 S.

2005-05-01

As the Army transforms into the Future Force, particular attention must be paid to operations in Complex and Urban Terrain. Our adversaries increasingly draw us into operations in the urban environment and one can presume that this trend will continue in future battles. In order to ensure that the United States Army maintains battlefield dominance, the Army Research Laboratory (ARL) is developing technology to equip our soldiers for the urban operations of the future. Sophisticated soldier borne systems will extend sensing to the individual soldier, and correspondingly, allow the soldier to establish an accurate picture of their surrounding environment utilizing information from local and remote assets. Robotic platforms will be an integral part of the future combat team. These platforms will augment the team with remote sensing modalities, task execution capabilities, and enhanced communication systems. To effectively utilize the products provided by each of these systems, collected data must be exchanged in real time to all affected entities. Therefore, the Army Research Laboratory is also developing the technology that will be required to support high bandwidth mobile communication in urban environments. This technology incorporates robotic systems that will allow connectivity in areas unreachable by traditional systems. This paper will address some of the issues of providing wireless connectivity in complex and urban terrain. It will further discuss approaches developed by the Army Research Laboratory to integrate communications capabilities into soldier and robotic systems and provide seamless connectivity between the elements of a combat team, and higher echelons.

Adopting public health approaches to communication disability: challenges for the education of speech-language pathologists.

Wylie, Karen; McAllister, Lindy; Davidson, Bronwyn; Marshall, Julie; Law, James

2014-01-01

Public health approaches to communication disability challenge the profession of speech-language pathology (SLP) to reconsider both frames of reference for practice and models of education. This paper reviews the impetus for public health approaches to communication disability and considers how public health is, and could be, incorporated into SLP education, both now and in the future. The paper describes tensions between clinical services, which have become increasingly specialized, and public health approaches that offer a broader view of communication disability and communication disability prevention. It presents a discussion of these tensions and asserts that public health approaches to communication are themselves a specialist field, requiring specific knowledge and skills. The authors suggest the use of the term 'communication disability public health' to refer to this type of work and offer a preliminary definition in order to advance discussion. Examples from three countries are provided of how some SLP degree programmes are integrating public health into the SLP curriculum. Alternative models of training for communication disability public health that may be relevant in the future in different contexts and countries are presented, prompting the SLP profession to consider whether communication disability public health is a field of practice for speech-language pathologists or whether it has broader workforce implications. The paper concludes with some suggestions for the future which may advance thinking, research and practice in communication disability public health. © 2015 S. Karger AG, Basel.

Person-centered psychiatric services rely on consumers actively sharing personal information, opinions, and preferences with their providers. This research examined predictors of consumer communication during appointments for psychiatric medication prescriptions. The Roter Interaction Analysis System was used to code recorded Veterans Affairs psychiatric appointments with 175 consumers and 21 psychiatric medication prescribers and categorize communication by purpose: biomedical, psychosocial, facilitation, or rapport-building. Regression analyses found that greater provider communication, symptomology, orientation to psychiatric recovery, and functioning on the Repeatable Battery for the Assessment of Neuropsychological Status Attention and Language indices, as well as consumer diagnostic label, were positive predictors of consumer communication, though the types of communication impacted varied. Provider communication is the easiest variable to intervene on to create changes in consumer communication. Future research should also consider how cognitive and symptom factors may impact specific types of consumer communication in order to identify subgroups for targeted interventions.

Providing a detailed description of two participants who failed to acquire functional communication skills following a verbal modelling intervention and Picture Exchange Communication System (PECS) training. Single-case research; Independent verbal requests, imitated verbal requests, word approximations and independent picture requests were assessed in a toddler and a pre-schooler with autism before and during two interventions. Although both participants used some vocalizations over the course of the study, experimental control was not demonstrated and the participants did not acquire a functional communication system prior to the cessation of intervention. Future research should include additional, detailed reports that provide insight to why some children with autism do not respond to particular communication interventions and should investigate the pairing of particular child characteristics with targeted interventions.

Communication Optimizations for a Wireless Distributed Prognostic Framework

Saha, Sankalita; Saha, Bhaskar; Goebel, Kai

2009-01-01

Distributed architecture for prognostics is an essential step in prognostic research in order to enable feasible real-time system health management. Communication overhead is an important design problem for such systems. In this paper we focus on communication issues faced in the distributed implementation of an important class of algorithms for prognostics - particle filters. In spite of being computation and memory intensive, particle filters lend well to distributed implementation except for one significant step - resampling. We propose new resampling scheme called parameterized resampling that attempts to reduce communication between collaborating nodes in a distributed wireless sensor network. Analysis and comparison with relevant resampling schemes is also presented. A battery health management system is used as a target application. A new resampling scheme for distributed implementation of particle filters has been discussed in this paper. Analysis and comparison of this new scheme with existing resampling schemes in the context for minimizing communication overhead have also been discussed. Our proposed new resampling scheme performs significantly better compared to other schemes by attempting to reduce both the communication message length as well as number total communication messages exchanged while not compromising prediction accuracy and precision. Future work will explore the effects of the new resampling scheme in the overall computational performance of the whole system as well as full implementation of the new schemes on the Sun SPOT devices. Exploring different network architectures for efficient communication is an importance future research direction as well.

Personal reflections on the multichannel cochlear implant and a view of the future.

Clark, Graeme M

2008-01-01

The multichannel cochlear implant is the first neural prosthesis to effectively and safely bring electronic technology into a direct physiological relation with the central nervous system and human consciousness. It is also the first cochlear implant to give speech understanding to tens of thousands of persons with profound deafness and spoken language to children born deaf in more than 80 countries. In so doing, it is the first major advance in research and technology to help deaf children communicate since Sign Language of the Deaf was developed at the Paris deaf school (L'Institut National de Jeunes Sourds de Paris) >200 years ago. Furthermore, biomedical research has been fundamental for ensuring that the multielectrode implant is safe as well as effective. More recent research has also shown that bilateral implants confer the benefits of binaural hearing. Future research using nanotechnology should see high-fidelity sound received, which would help deaf persons communicate in noise and enjoy music. Research should also lead to implants in ears with useful hearing.

Qualitative research can capture the meaningful experiences and life values of persons with dementia not reported in quantitative studies. This researcher shares personal experience of the challenges faced and the lessons learned while conducting a qualitative study of 15 persons with early stage Alzheimer’s disease. The purpose of this paper is to discuss the issues concerning determination of capacity to consent to research, consent/assent, communication challenges, and trustworthiness of data when conducting a qualitative study of persons with dementia. Understanding communication challenges due to dementia is important to develop effective communication strategies, such as simplifying the structure of questions, allowing ample time for participant’s response, using reminiscence, and redirecting the dialogue. This information will be valuable to researchers conducting future qualitative studies and the resulting contributions to the body of knowledge about Alzheimer’s PMID:20077988

Chesnut, Steven R; Wei, Tianlan; Barnard-Brak, Lucy; Richman, David M

2017-11-01

The current meta-analysis examines the previous research on the utility of the Social Communication Questionnaire as a screening instrument for autism spectrum disorder. Previously published reports have highlighted the inconsistencies between Social Communication Questionnaire-screening results and formal autism spectrum disorder diagnoses. The variations in accuracy resulted in some researchers questioning the validity of the Social Communication Questionnaire. This study systematically examined the accuracy of the Social Communication Questionnaire as a function of the methodological decisions made by researchers screening for autism spectrum disorder over the last 15 years. Findings from this study suggest that the Social Communication Questionnaire is an acceptable screening instrument for autism spectrum disorder (area under the curve = 0.885). Variations in methodological decisions, however, greatly influenced the accuracy of the Social Communication Questionnaire in screening for autism spectrum disorder. Of these methodological variations, using the Current instead of the Lifetime version of the Social Communication Questionnaire resulted in the largest detrimental effect ( d = -3.898), followed by using the Social Communication Questionnaire with individuals younger than 4 years of age ( d = -2.924) and relying upon convenience samples ( d = -4.828 for clinical samples, -2.734 for convenience samples, and -1.422 for community samples). Directions for future research and implications for using the Social Communication Questionnaire to screen for autism spectrum disorder are discussed.

Satisfaction, compliance and communication.

PubMed

Ley, P

1982-11-01

The literature on communication, compliance, and patient satisfaction is selectively reviewed. As in earlier reviews, it is concluded that dissatisfaction with communication remains widespread, as does lack of compliance with medical advice. Related factors include poor transmission of information from patient to doctor, low understandability of communications addressed to the patient, and low levels of recall of information by patients. There does not appear to be any evidence that provision of additional information leads to adverse reactions by patients. Theoretical approaches to communication and compliance are described, and it is concluded that these should be used to direct future research.

Unmanned Aircraft System Control and ATC Communications Bandwidth Requirements

NASA Technical Reports Server (NTRS)

Henriksen, Steve

2008-01-01

There are significant activities taking place to establish the procedures and requirements for safe and routine operation of unmanned aircraft systems (UAS) in the National Airspace System (NAS). Among the barriers to overcome in achieving this goal is the lack of sufficient frequency spectrum necessary for the UAS control and air traffic control (ATC) communications links. This shortcoming is compounded by the fact that the UAS control communications links will likely be required to operate in protected frequency spectrum, just as ATC communications links are, because they relate to "safety and regularity of flight." To support future International Telecommunications Union (ITU) World Radio Conference (WRC) agenda items concerning new frequency allocations for UAS communications links, and to augment the Future Communications Study (FCS) Technology Evaluation Group efforts, NASA Glenn Research Center has sponsored a task to estimate the UAS control and ATC communications bandwidth requirements for safe, reliable, and routine operation of UAS in the NAS. This report describes the process and results of that task. The study focused on long-term bandwidth requirements for UAS approximately through 2030.

As scientists and engineers primarily employed by the public, we have a responsibility to "communicate the results of our research so that the average American could understand that NASA is an investment in our future...". Not only are we employed by the public, but they are also the source of future generations of scientists and engineers. Teachers typically don't have the time or expertise to research recent advances in space science and reduce them to a form that students can absorb. Teachers are also often intimidated by both the subject and the researchers themselves. Therefore, the burden falls on us - the space scientists and engineers of the world - to communicate our findings in ways both teachers and students can understand. Student Nanoexperiments for Outreach and Observational Planetary InquirY (SNOOPY) provides just such an opportunity to directly involve our customers in planetary science missions.

The Premarital Communication Roots of Marital Distress and Divorce: The First Five Years of Marriage

PubMed Central

Markman, Howard J.; Rhoades, Galena K.; Stanley, Scott M.; Ragan, Erica P.; Whitton, Sarah W.

2011-01-01

Using data from 210 couples who provided data across the first five years of marriage, we examined how premarital communication quality was related to divorce and later distress. The results showed that premarital observed negative and positive communication nearly reached significance as predictors of divorce, while self-reported negative communication was significantly associated with divorce. In terms of marital adjustment, we found that both premarital observed and self-reported negative premarital communication (but not observed positive communication) were associated with lower adjustment during the first five years of marriage. The most important questions addressed in this study pertain to how positive and negative dimensions of communication change over time and how these changes are related to being distressed or nondistressed after five years of marriage. This is the first study, to our knowledge, to examine the changes in communication over time that are so central to theories of the development of marital distress and for research based interventions. We found that all couples showed decreases in negative communication over time, but the non-distressed group declined significantly more than the distressed group in negative communication, suggesting they are handling negative emotions better. Implications for future research on the development of relationship distress and for enhancing research-based couples intervention programs are provided. PMID:20545402

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

PubMed

Ishikawa, Hirono; Hashimoto, Hideki; Kiuchi, Takahiro

2013-11-01

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

Semiochemicals released by plants or insects play an important role in the communication among plants, phytophagous insects and their natural enemies. They thus form a chemical information network which regulates intra- and inter-specific behaviors and sustains the composition and structure of plant and insect communities. The application of insect-resistant genetically modified (IRGM) crops may affect the chemical communication within and among the tritrophic levels, and thus cause disturbances to the biotic community structure and the stability of the farmland ecosystem. This has raised concerns about the environmental safety of IRGM crops and triggered research worldwide. In the current article we provided a brief summary of the chemical communication among plants, herbivores and natural enemies; analyzed the potential of IRGM crops to affect the chemical communication between plants and arthropods and the related mechanisms; and discussed the current research progress and the future prospects in this field. We hope that this will promote the research in this field by Chinese scientists and increase our understanding of the potential effects of growing of IRGM crops on the arthropod community structure.

Lewis Information Network (LINK): Background and overview

NASA Technical Reports Server (NTRS)

Schulte, Roger R.

1987-01-01

The NASA Lewis Research Center supports many research facilities with many isolated buildings, including wind tunnels, test cells, and research laboratories. These facilities are all located on a 350 acre campus adjacent to the Cleveland Hopkins Airport. The function of NASA-Lewis is to do basic and applied research in all areas of aeronautics, fluid mechanics, materials and structures, space propulsion, and energy systems. These functions require a great variety of remote high speed, high volume data communications for computing and interactive graphic capabilities. In addition, new requirements for local distribution of intercenter video teleconferencing and data communications via satellite have developed. To address these and future communications requirements for the next 15 yrs, a project team was organized to design and implement a new high speed communication system that would handle both data and video information in a common lab-wide Local Area Network. The project team selected cable television broadband coaxial cable technology as the communications medium and first installation of in-ground cable began in the summer of 1980. The Lewis Information Network (LINK) became operational in August 1982 and has become the backbone of all data communications and video.

The National Aeronautics and Space Administration (NASA) Glenn Research Center (GRC) is investigating current and anticipated wireless communications concepts and technologies that the National Airspace System (NAS) may need in the next 50 years. NASA has awarded three NASA Research Announcements (NAR) studies with the objective to determine the most promising candidate technologies for air-to-air and air-to-ground data exchange and analyze their suitability in a post-NextGen NAS environment. This paper will present progress made in the studies and describe the communications challenges and opportunities that have been identified as part of the study. NASA's NextGen Concepts and Technology Development (CTD) Project integrates solutions for a safe, efficient and high-capacity airspace system through joint research efforts and partnerships with other government agencies. The CTD Project is one of two within NASA's Airspace Systems Program and is managed by the NASA Ames Research Center. Research within the CTD Project is in support the 2011 NASA Strategic Plan Sub-Goal 4.1: Develop innovative solutions and advanced technologies, through a balanced research portfolio, to improve current and future air transportation. The focus of CTD is on developing capabilities in traffic flow management, dynamic airspace configuration, separation assurance, super density operations and airport surface operations. Important to its research is the development of human/automation information requirements and decisionmaking guidelines for human-human and human-machine airportal decision-making. Airborne separation, oceanic intrail climb/descent and interval management applications depend on location and intent information of surrounding aircraft. ADS-B has been proposed to provide the information exchange, but other candidates such as satellite-based receivers, broadband or airborne internet, and cellular communications are possible candidate's.

1995-01-01

A laboratory glass-cockpit flight simulator supporting research on advanced commercial flight deck and Air Traffic Control (ATC) automation and communication interfaces has been developed at the Aviation Operations Branch at the NASA Ames Research Center. This system provides independent and integrated flight and ATC simulator stations, party line voice and datalink communications, along with video and audio monitoring and recording capabilities. Over the last several years, it has been used to support the investigation of flight human factors research issues involving: communication modality; message content and length; graphical versus textual presentation of information, and human accountability for automation. This paper updates the status of this simulator, describing new functionality in the areas of flight management system, EICAS display, and electronic checklist integration. It also provides an overview of several experiments performed using this simulator, including their application areas and results. Finally future enhancements to its ATC (integration of CTAS software) and flight deck (full crew operations) functionality are described.

A recent surge of research universities and human subjects research funding in the Arab world raises concerns about applied research ethics and oversight. In-depth interviews conducted with 52 researchers in Lebanon and Qatar about their research conduct and the problems they face while conducting it indicate that although researchers admit to the added value of institutional review board (IRB) functions, the researchers have several complaints, such as rigid and contextually insensitive requirements, delays, and inadequate resources at IRBs, and a lack of outreach and effective communication with researchers. The study discusses these challenges pointing to the need for socioculturally adaptive regulations and forms and strengthening outreach and communication between IRBs and their users to improve ethical practices. Implications for future research are also presented. © The Author(s) 2014.

Placebo Analgesia in Rodents: Current and Future Research

Keller, Asaf; Akintola, Titilola; Colloca, Luana

2018-01-01

The investigation of placebo effects in animal pain models has received less attention than human research. This may be related to a number of difficulties, including the fact that animals lack the ability to use language and establish expectancies verbally, that animals cannot report and rate the extent to which they experience pain, and the inadequacy of current models of pain. Here, we describe the relatively small number of studies that have been published, communicating the opportunities and excitement of this research. We critically discuss pitfalls and limitations with the hope that this will advance future animal placebo-related research. PMID:29681320

Since 2000, the field of health communication has grown tremendously, owing largely to research funding by the National Cancer Institute (NCI). This study provides an overview of cancer communication science funding trends in the past decade. We conducted an analysis of communication-related grant applications submitted to the NCI in fiscal years 2000-2012. Using 103 keywords related to health communication, data were extracted from the Portfolio Management Application, a grants management application used at NCI. Automated coding described key grant characteristics such as mechanism and review study section. Manual coding determined funding across the cancer control continuum, by cancer site, and by cancer risk factors. A total of 3307 unique grant applications met initial inclusion criteria; 1013 of these were funded over the 12-year period. The top funded grant mechanisms were the R01, R21, and R03. Applications were largely investigator-initiated proposals as opposed to responses to particular funding opportunity announcements. Among funded communication research, the top risk factor being studied was tobacco, and across the cancer control continuum, cancer prevention was the most common stage investigated. NCI support of cancer communication research has been an important source of growth for health communication science over the last 12 years. The analysis' findings describe NCI's priorities in cancer communication science and suggest areas for future investments.

Environmental care in agricultural catchments: Toward the communicative catchment

NASA Astrophysics Data System (ADS)

Martin, Peter

1991-11-01

Substantial land degradation of agricultural catchments in Australia has resulted from the importation of European farming methods and the large-scale clearing of land. Rural communities are now being encouraged by government to take responsibility for environmental care. The importance of community involvement is supported by the view that environmental problems are a function of interactions between people and their environment. It is suggested that the commonly held view that community groups cannot care for their resources is due to inappropriate social institutions rather that any inherent disability in people. The communicative catchment is developed as a vision for environmental care into the future. This concept emerges from a critique of resource management through the catchment metaphors of the reduced, mechanical, and the complex, evolving catchment, which reflect the development of systemic and people-centered approaches to environmental care. The communicative catchment is one where both community and resource managers participate collaboratively in environmental care. A methodology based on action research and systemic thinking (systemic action research) is proposed as a way of moving towards the communicative catchment of the future. Action research is a way of taking action in organizations and communities that is participative and informed by theory, while systemic thinking takes into account the interconnections and relationships between social and natural worlds. The proposed vision, methodology, and practical operating principles stem from involvement in an action research project looking at extension strategies for the implementation of total catchment management in the Hunter Valley, New South Wales.

2014-01-01

In the new era of connectivity, marked by the explosive number of wireless electronic devices and the need for smart and pervasive applications, Machine-to-Machine (M2M) communications are an emerging technology that enables the seamless device interconnection without the need of human interaction. The use of M2M technology can bring to life a wide range of mHealth applications, with considerable benefits for both patients and healthcare providers. Many technological challenges have to be met, however, to ensure the widespread adoption of mHealth solutions in the future. In this context, we aim to provide a comprehensive survey on M2M systems for mHealth applications from a wireless communication perspective. An end-to-end holistic approach is adopted, focusing on different communication aspects of the M2M architecture. Hence, we first provide a systematic review of Wireless Body Area Networks (WBANs), which constitute the enabling technology at the patient's side, and then discuss end-to-end solutions that involve the design and implementation of practical mHealth applications. We close the survey by identifying challenges and open research issues, thus paving the way for future research opportunities. PMID:25264958

Probabilities, uncertainties, statistics, science, and threats are notoriously difficult topics to communicate with members of the public. The Operational Earthquake Forecast (OEF) is designed to provide an understanding of potential numbers and sizes of earthquakes and the communication of it must address all of those challenges. Furthermore, there are other barriers to effective communication of the OEF. These barriers include the erosion of trust in scientists and experts, oversaturation of messages, fear and threat messages magnified by the sensalisation of the media, fractured media environments and online echo chambers. Given the complexities and challenges of the OEF, how can we overcome barriers to effective communication? Crisis and risk communication research can inform the development of communication strategies to increase the public understanding and use of the OEF, when applied to the opportunities and challenges of practice. We explore ongoing research regarding how the OEF can be more effectively communicated - including the channels, tools and message composition to engage with a variety of publics. We also draw on past experience and a study of OEF communication during the Canterbury Earthquake Sequence (CES). We demonstrate how research and experience has guided OEF communications during subsequent events in New Zealand, including the M5.7 Valentine's Day earthquake in 2016 (CES), M6.0 Wilberforce earthquake in 2015, and the Cook Strait/Lake Grassmere earthquakes in 2013. We identify the successes and lessons learned of the practical communication of the OEF. Finally, we present future projects and directions in the communication of OEF, informed by both practice and research.

Multi-dimensional perspectives of flood risk - using a participatory framework to develop new approaches to flood risk communication

NASA Astrophysics Data System (ADS)

Rollason, Edward; Bracken, Louise; Hardy, Richard; Large, Andy

2017-04-01

Flooding is a major hazard across Europe which, since, 1998 has caused over €52 million in damages and displaced over half a million people. Climate change is predicted to increase the risks posed by flooding in the future. The 2007 EU Flood Directive cemented the use of flood risk maps as a central tool in understanding and communicating flood risk. Following recent flooding in England, an urgent need to integrate people living at risk from flooding into flood management approaches, encouraging flood resilience and the up-take of resilient activities has been acknowledged. The effective communication of flood risk information plays a major role in allowing those at risk to make effective decisions about flood risk and increase their resilience, however, there are emerging concerns over the effectiveness of current approaches. The research presented explores current approaches to flood risk communication in England and the effectiveness of these methods in encouraging resilient actions before and during flooding events. The research also investigates how flood risk communications could be undertaken more effectively, using a novel participatory framework to integrate the perspectives of those living at risk. The research uses co-production between local communities and researchers in the environmental sciences, using a participatory framework to bring together local knowledge of flood risk and flood communications. Using a local competency group, the research explores what those living at risk from flooding want from flood communications in order to develop new approaches to help those at risk understand and respond to floods. Suggestions for practice are refined by the communities to co-produce recommendations. The research finds that current approaches to real-time flood risk communication fail to forecast the significance of predicted floods, whilst flood maps lack detailed information about how floods occur, or use scientific terminology which people at risk find confusing or lacking in realistic grounding. This means users do not have information they find useful to make informed decisions about how to prepare for and respond to floods. Working together with at-risk participants, the research has developed new approaches for communicating flood risk. These approaches focus on understanding flood mechanisms and dynamics, to help participants imagine their flood risk and link potential scenarios to reality, and provide forecasts of predicted flooding at a variety of scales, allowing participants to assess the significance of predicted flooding and make more informed judgments on what action to take in response. The findings presented have significant implications for the way in which flood risk is communicated, changing the focus of mapping from probabilistic future scenarios to understanding flood dynamics and mechanisms. Such ways of communicating flood risk embrace how people would like to see risk communicated, and help those at risk grow their resilience. Communicating in such a way has wider implications for flood modelling and data collection. However, these represent potential opportunities to build more effective local partnerships for assessing and managing flood risks.

Enabling Arctic Research Through Science and Engineering Partnerships

Under an Arctic Research Support and Logistics contract from NSF (GEO/PLR), SRI International, as part of the CH2M HILL Polar Services (CPS) program, forms partnerships with Arctic research teams to provide data transfer, remote operations, and safety/operations communications. This teamwork is integral to the success of real-time science results and often allows for unmanned operations which are both cost-effective and safer. The CPS program utilizes a variety of communications networks, services and technologies to support researchers and instruments throughout the Arctic, including Iridium, VSAT, Inmarsat BGAN, HughesNet, TeleGreenland, radios, and personal locator beacons. Program-wide IT and communications limitations are due to the broad categories of bandwidth, availability, and power. At these sites it is essential to conserve bandwidth and power through using efficient software, coding and scheduling techniques. There are interesting new products and services on the horizon that the program may be able to take advantage of in the future such as Iridium NEXT, Inmarsat Xpress, and Omnispace mobile satellite services. Additionally, there are engineering and computer software opportunities to develop more efficient products. We will present an overview of science/engineering partnerships formed by the CPS program, discuss current limitations and identify future technological possibilities that could further advance Arctic science goals.

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

This paper reports on the workshop 'Genetic Counseling/Consultations in South-East Asia' at the 10(th) Asia Pacific Conference on Human Genetics in Kuala Lumpur, Malaysia, in December 2012. The workshop brought together professionals and language/communication scholars from South-East Asia, and the UK. The workshop aimed at addressing culture- and context-specific genetic counseling/consultation practices in South-East Asia. As a way of contextualizing genetic counseling/consultation in South-East Asia, we first offer an overview of communication-oriented research generally, drawing attention to consultation and counseling as part of a communicative continuum with distinctive interactional features. We then provide examples of genetic counseling/consultation research in Hong Kong. As other countries in South-East Asia have not yet embarked on communication-oriented empirical research, we report on the current practices of genetic counseling/consultation in these countries in order to identify similarities and differences as well as key obstacles that could be addressed through future research. Three issues emerged as 'problematic': language, religion and culture. We suggest that communication-oriented research can provide a starting point for evidence-based reflections on how to incorporate a counseling mentality in genetic consultation. To conclude, we discuss the need for creating a platform for targeted training of genetic counselors based on communication-oriented research findings.

The Use of Social Networking Sites (SNSs) in Health Communication Campaigns: Review and Recommendations.

PubMed

Shi, Jingyuan; Poorisat, Thanomwong; Salmon, Charles T

2018-01-01

The past decade has witnessed a rapid increase in the use of Social Networking Sites (SNSs) in health communication campaigns seeking to achieve an ambitious range of health-related impacts. This article provides a review of 40 studies and research protocols, with a focus on two key factors that differentiate SNSs from more traditional health communication approaches of the past. The first is the potential dualism between message sender and receiver, in which receivers become receiver-sources who forward and amplify the content and reach of health messages. The second is the potential dualism between message and message impact, in which the act of forwarding and modifying messages by receiver-sources itself becomes a measure of message impact. Each of these dualisms has implications for the design and evaluation of contemporary health communication campaigns. The review concludes with a series of observations and recommendations for future health communication research.

Uncovering Factors Influencing Interpersonal Health Communication

Donné, Lennie; Jansen, Carel; Hoeks, John

2017-01-01

Talking to friends, family, or peers about health issues might, among other things, increase knowledge of social norms and feelings of self-efficacy in adopting a healthier lifestyle. We often see interpersonal health communication as an important mediating factor in the effects of health campaigns on health behavior. No research has been done so far, however, on factors that influence whether and how people talk about health issues without being exposed to a health campaign first. In this exploratory study, we interviewed 12 participants about their communication behavior concerning six different health themes, like smoking and exercising. The results suggest that at least four types of interpersonal health communication can be distinguished, each influenced by different factors, like conversational partner and objective of the conversation. Future research should take this diversity of interpersonal health communication into account, and focus on designing health campaigns that aim to trigger dialogue within target populations.

Lightwave communications is a necessity for the information age. Optical links provide enormous bandwidth, and the optical fiber is the only medium that can meet the modern society's needs for transporting massive amounts of data over long distances. Applications range from global high-capacity networks, which constitute the backbone of the internet, to the massively parallel interconnects that provide data connectivity inside datacenters and supercomputers. Optical communications is a diverse and rapidly changing field, where experts in photonics, communications, electronics, and signal processing work side by side to meet the ever-increasing demands for higher capacity, lower cost, and lower energy consumption, while adapting the system design to novel services and technologies. Due to the interdisciplinary nature of this rich research field, Journal of Optics has invited 16 researchers, each a world-leading expert in their respective subfields, to contribute a section to this invited review article, summarizing their views on state-of-the-art and future developments in optical communications.

A review of the efficacy of the picture exchange communication system intervention.

PubMed

Preston, Deborah; Carter, Mark

2009-10-01

The Picture Exchange Communication System (PECS) is a communication program that has become widely used, especially with children with autism. This paper reports the results of a review of the empirical literature on PECS. A descriptive review is provided of the 27 studies identified, which included randomized controlled trials (RCTs), other group designs and single subject studies. For 10 appropriate single subject designs the percentage of nonoverlapping data (PND) and percentage exceeding median (PEM) metrics were examined. While there are few RCTs, on balance, available research provides preliminary evidence that PECS is readily learned by most participants and provides a means of communication for individuals with little or no functional speech. Very limited data suggest some positive effect on both social-communicative and challenging behaviors, while effects on speech development remain unclear. Directions for future research are discussed including the priority need for further well-conducted RCTs.

Scientists and Science Education: Working at the Interface

"Are we alone?" "Where did we come from?" "What is our future?" These questions lie at the juncture of astronomy and biology: astrobiology. It is intrinsically interdisciplinary in its study of the origin, evolution and future of life on Earth and beyond. The fundamental concepts of origin and evolution--of both living and non-living systems--are central to astrobiology, and provide powerful themes for unifying science teaching, learning, and appreciation in classrooms and laboratories, museums and science centers, and homes. Research scientists play a key role in communicating the nature of science and joy of scientific discovery with the public. Communicating the scientific discoveries with the public brings together diverse professionals: research scientists, graduate and undergraduate faculty, educators, journalists, media producers, web designers, publishers and others. Working with these science communicators, research scientists share their discoveries through teaching, popular articles, lectures, broadcast and print media, electronic publication, and developing materials for formal and informal education such as textbooks, museum exhibits and documentary television. There's lots of activity in science communication. Yet, the NSF and NASA have both identified science education as needing improvement. The quality of schools and the preparation of teachers receive national attention via "No Child Left Behind" requirements. The number of students headed toward careers in science, technology, engineering and mathematics (STEM) is not sufficient to meet national needs. How can the research community make a difference? What role can research scientists fulfill in improving STEM education? This talk will discuss the interface between research scientists and science educators to explore effective roles for scientists in science education partnerships. Astronomy and astrobiology education and outreach projects, materials, and programs will provide the context for this discussion.

Anticipate and communicate: Ethical management of incidental and secondary findings in the clinical, research, and direct-to-consumer contexts (December 2013 report of the Presidential Commission for the Study of Bioethical Issues).

Genomic population research increases the possibility of finding genetic coding anomalies that are not the primary object of research but may have significance for the current and future medical care of research participants and progeny. The December 2013 Report of the Presidential Commission for the Study of Bioethical Issues (Anticipate and Communicate: Ethical Management of Incidental and Secondary Findings in the Clinical, Research, and Direct-to-Consumer Contexts (http://bioethics.gov/sites/default/files/FINALAnticipateCommunicate_PCSBI_0.pdf)) recommends that a researcher anticipate these findings and make a plan that addresses which findings will be communicated to research participants and how. Following these recommendations will be disruptive for both investigators and institutional review boards (IRBs) until the research community reaches consensus, or a mechanism for evolving consensus, on which results should be returned to research participants. A protocol-by-protocol approach, though laborious, makes sense for both investigators and IRBs as the research community thinks through the implications of genomic research. Epidemiologists will note that discussion of the return of results and the plan for communicating findings should be included in both the participant consent agreement and the research protocol submitted to the IRB. © The Author 2014.

Social cognitive mediators of parent-child sexual communication.

PubMed

Evans, W Douglas; Blitstein, Jonathan L; Davis, Kevin C

2011-07-01

To test a social cognitive behavior change model and identify mediators of the effects of the Parents Speak Up National Campaign (PSUNC) on parent-child sexual communication. Investigators used 5 waves of data from an online randomized controlled trial. Latent variables were developed based on item response theory and confirmatory factor analysis. Structural equation modeling was used to test mediation. Outcome expectations mediated effects of social norms and self-efficacy on sexual communication. Other hypothesized mediators were not confirmed. Interventions to promote parent-child sexual communication should target outcome expectations. Future research should investigate parents' health information seeking.

Neuroscience has identified brain structures and functions that correlate with psychopathic tendencies. Since psychopathic traits can be traced back to physical neural attributes, it has been argued that psychopaths are not truly responsible for their actions and therefore should not be blamed for their psychopathic behaviors. This experimental research aims to evaluate what effect communicating this theory of psychopathy has on the moral behavior of lay people. If psychopathy is blamed on the brain, people may feel less morally responsible for their own psychopathic tendencies and therefore may be more likely to display those tendencies. An online study will provide participants with false feedback about their psychopathic traits supposedly based on their digital footprint (i.e., Facebook likes), thus classifying them as having either above-average or below-average psychopathic traits and describing psychopathy in cognitive or neurobiological terms. This particular study will assess the extent to which lay people are influenced by feedback regarding their psychopathic traits, and how this might affect their moral behavior in online tasks. Public recognition of these potential negative consequences of neuroscience communication will also be assessed. A field study using the lost letter technique will be conducted to examine lay people’s endorsement of neurobiological, as compared to cognitive, explanations of criminal behavior. This field and online experimental research could inform the future communication of neuroscience to the public in a way that is sensitive to the potential negative consequences of communicating such science. In particular, this research may have implications for the future means by which neurobiological predictors of offending can be safely communicated to offenders. PMID:28352238

Communication that heals: mindful communication practices from palliative care leaders.

PubMed

Omilion-Hodges, Leah M; Swords, Nathan M

2016-01-01

Though research has begun to highlight the centrality of communication in palliative care, studies have yet to focus on the use of mindful communication. Mindful communication is associated with increases in patient care and decreases in physician burnout. Through in-depth, semi-structured interviews the authors sought mindful communication practices from palliative care leaders in American Hospital Association Circle of Life® award-wining units. Four key mindful communication practices emerged: Know your audience, ask questions, discard scripts, and recognize your role. The discussion articulates how key mindful communication practices may be used as a stage model, where key practices may be used individually or in concert, by sole practitioners or within interdisciplinary teams and by new and seasoned clinicians. Theoretical contributions and areas for future inquiry are also discussed.

Application of technology to social communication impairment in childhood and adolescence.

Wieckowski, Andrea Trubanova; White, Susan W

2017-03-01

Social communication impairment has been implicated in various mental health disorders. The primary aim of this review paper is to summarize the extant research on the development and application of technologies to address social communication deficits, conceptualized according to the four constructs outlined by the NIMH's Research Domain Criteria (RDoC), transdiagnostically in children and adolescents. An exhaustive and systematic search yielded 69 peer-reviewed articles meeting all inclusion criteria (i.e., used technology, applied the technology to target impairment in at least one of four constructs of social communication, included a child or adolescent samples). We found limited use of technology for exploration of impairment in reception of non-facial communication, compared to the other social communication constructs. In addition, there has been an overwhelming focus on social communication impairment in children and adolescents with Autism Spectrum Disorder (ASD), with relatively few studies evaluating technology application in other clinical populations. Implications for future directions for technological interventions to treat social communication impairments transdiagnostically are discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

"My World Has Expanded Even Though I'm Stuck at Home": Experiences of Individuals With Amyotrophic Lateral Sclerosis Who Use Augmentative and Alternative Communication and Social Media.

PubMed

Caron, Jessica; Light, Janice

2015-11-01

This study aimed to expand the current understanding of how persons with amyotrophic lateral sclerosis (pALS) use augmentative and alternative communication and social media to address their communication needs. An online focus group was used to investigate the experiences of 9 pALS who use augmentative and alternative communication and social media. Questions posed to the group related to (a) current use of social media, (b) advantages of social media, (c) barriers to independent use, (d) supports to independent use, and (e) recommendations for developers, policy makers, and other pALS. Participants primarily reported that use of social media was a beneficial tool that provided increased communication opportunities, connections to communication partners, and networks of support. Specific results are discussed with reference to the research as well as implications for practice and recommendations for future research. As individuals with ALS experience loss of function, some communication modes may no longer be viable. Providing access to different modes of communication, including social media, can allow independence, participation and better quality of life.

The premarital communication roots of marital distress and divorce: the first five years of marriage.

Markman, Howard J; Rhoades, Galena K; Stanley, Scott M; Ragan, Erica P; Whitton, Sarah W

2010-06-01

Using data from 210 couples who provided data across the first 5 years of marriage, we examined how premarital communication quality was related to divorce and later distress. The results showed that premarital observed negative and positive communication nearly reached significance as predictors of divorce, while self-reported negative communication was significantly associated with divorce. In terms of marital adjustment, we found that both premarital observed and self-reported negative premarital communication (but not observed positive communication) were associated with lower adjustment during the first 5 years of marriage. The most important questions addressed in this study pertain to how positive and negative dimensions of communication change over time and how these changes are related to being distressed or nondistressed after 5 years of marriage. This is the first study, to our knowledge, to examine the changes in communication over time that are so central to theories of the development of marital distress and for research-based interventions. We found that all couples showed decreases in negative communication over time, but the nondistressed group declined significantly more than the distressed group in negative communication, suggesting they are handling negative emotions better. Implications for future research on the development of relationship distress and for enhancing research-based couples' intervention programs are provided. (c) 2010 APA, all rights reserved.

2016-01-01

Objective This formative study examined perceptions of e-cigarettes in college students with the goal of informing future health communication campaigns. Differences between e-cigarette users and nonusers were also examined. Participants: Thirty undergraduate students were recruited from a large southwestern public university (15 users, 15 nonusers). Methods Structured interviews were conducted and transcripts were coded for themes. Results Although users had more favorable attitudes toward e-cigarettes, both users and nonusers believed that e-cigarettes produce water vapor and reported that e-cigarettes were less harmful than conventional cigarettes. Potential health consequences and addiction concerns were the most common perceived threats for both users and nonusers. Both nonusers and users cited social stigma as a perceived disadvantage of e-cigarette use. Conclusions Ultimately, themes with particular relevance to future health communication campaigns included negative perceptions of e-cigarette users and social stigma, as well as harm perceptions and potential health consequences associated with e-cigarette use.

Toward The Goal Of Video Deaf Communication Over Public Telephone Lines

NASA Astrophysics Data System (ADS)

Healy, Donald J.; Clements, Mark A.

1986-11-01

At least 500,000 profoundly deaf persons in the United States communicate primarily by American Sign Language (ASL), a language quite distinct from English and not well suited to writing. Currently, telephone communication for an ASL user is basically limited to use of a teletype machine, which requires both typing skills and proficiency in English. This paper reviews recent research relevant to the development of techniques which would allow manual communication across existing telephone channels using video imagery. Two possibilities for such manual communication are ASL and cued speech. The latter technique uses hand signals to aid lip reading. In either case, conventional television video transmission would require a bandwidth many times that available on a telephone channel. The achievement of visual communication using sign language or cued speech at data rates below 10 kbps, low enough to be transmitted over a public telephone line, will require the development of new data reducing algorithms. Avenues for future research toward this goal are presented.

Improving laboratory animal science and welfare requires both new scientific research and insights from research in the humanities and social sciences. Whilst scientific research provides evidence to replace, reduce and refine procedures involving laboratory animals (the '3Rs'), work in the humanities and social sciences can help understand the social, economic and cultural processes that enhance or impede humane ways of knowing and working with laboratory animals. However, communication across these disciplinary perspectives is currently limited, and they design research programmes, generate results, engage users, and seek to influence policy in different ways. To facilitate dialogue and future research at this interface, we convened an interdisciplinary group of 45 life scientists, social scientists, humanities scholars, non-governmental organisations and policy-makers to generate a collaborative research agenda. This drew on methods employed by other agenda-setting exercises in science policy, using a collaborative and deliberative approach for the identification of research priorities. Participants were recruited from across the community, invited to submit research questions and vote on their priorities. They then met at an interactive workshop in the UK, discussed all 136 questions submitted, and collectively defined the 30 most important issues for the group. The output is a collaborative future agenda for research in the humanities and social sciences on laboratory animal science and welfare. The questions indicate a demand for new research in the humanities and social sciences to inform emerging discussions and priorities on the governance and practice of laboratory animal research, including on issues around: international harmonisation, openness and public engagement, 'cultures of care', harm-benefit analysis and the future of the 3Rs. The process outlined below underlines the value of interdisciplinary exchange for improving communication across different research cultures and identifies ways of enhancing the effectiveness of future research at the interface between the humanities, social sciences, science and science policy.

To review research on observed family communication in families with children with chronic illnesses compared with families with healthy, typically developing children, and to integrate findings utilizing a unifying family communication framework. Topical review of studies that have directly observed family communication in pediatric populations and included a typically developing comparison group. Initial findings from 14 studies with diverse approaches to quantifying observed family communication suggest that families with children with chronic illnesses may demonstrate lower levels of warm and structured communication and higher levels of hostile/intrusive and withdrawn communication compared with families with healthy, typically developing children. An integrative framework of family communication may be used in future studies that examine the occurrence, correlates, and mechanisms of family communication in pediatric populations.

Interactions between patients and dental care providers: does gender matter?

PubMed

Inglehart, Marita R

2013-04-01

Research findings concerning the role of gender in patient-physician interactions can inform considerations about the role of gender in patient-dental care provider interactions. Medical research showed that gender differences in verbal and nonverbal communication in medical settings exist and that they affect the outcomes of these interactions. The process of communication is shaped by gender identities, gender stereotypes, and attitudes. Future research needs to consider the cultural complexity and diversity in which gender issues are embedded and the degree to which ongoing value change will shape gender roles and in turn interactions between dental patients and their providers.

Objective: This research investigates the needs and opinions of radiologists on the use of enhanced information technologies and approaches to improve the functionality of Picture Archiving and Communication Systems (PACS). Method: Six interviews were conducted in the main governmental hospital in Kuwait (AL-Sabah Hospital) with radiologists, including two senior radiologists, two junior radiologists, and two trainee radiologists undertaking the Irish radiology board. Results: The radiologists identified a number of limitations that exist in current PACS and requirements to enhance usability and functionality. However, it was the case that some of the radiologists had little knowledge about the advanced trends in PACS. Four themes emerged from the thematic analysis of the data: (1) limitations of traditional PACS; (2) Features and requirements that can increase PACS functionality; (3) web based solutions of PACS; (4) PACS in mobile phones. Conclusion: It is widely recognized that PACS has limitations. This research has identified themes that, when incorporated, will enhance the functionality of PACS and provide better quality clinical practice. This research has determined the important future trends of PACS. Primarily web based solutions and use in mobile phones. The findings from this research can be used as recommendations to vendors, for product development and medical institutes to consider when undertaking implementation of PACS and training future radiologists.

In the province of Ontario, many of the public health units (PHUs) now possess and use social media as part of their daily health promotion and communication operations. To explore this topic, a planning meeting was held to generate deeper insights toward the use of these forms of technology for preventative services delivery. The planning meeting was held with 50 participants, comprising representatives from 20 of the 36 PHUs in Ontario, interested academics, students and government representatives. A nominal group technique (NGT) was used to build consensus related to future research needs, as related to public health and social media. Participants generated a range of insights around the use of social media, including the need for: leadership buy-in and resource allocation; social media policy and governance structure; performance measurement and evaluation; practices related to engagement with program recipients and addressing the lack of resources faced by many health units. Future research priorities were also generated, related to evaluating the cost-benefit of social media activities and understanding behaviour change implications. Further research is needed to evaluate the functionality, leadership and competency requirements and impact(s) of these new forms of health communication technology within public health service delivery.

Son, Youn-Jung; Lee, Soo-Kyoung; Nam, SeJin; Shim, Jae Lan

2018-05-04

This study used social network analysis to identify the main research topics and trends in nursing-related communication in intensive care units. Keywords from January 1967 to June 2016 were extracted from PubMed using Medical Subject Headings terms. Social network analysis was performed using Gephi software. Research publications and newly emerging topics in nursing-related communication in intensive care units were classified into five chronological phases. After the weighting was adjusted, the top five keyword searches were "conflict," "length of stay," "nursing continuing education," "family," and "nurses." During the most recent phase, research topics included "critical care nursing," "patient handoff," and "quality improvement." The keywords of the top three groups among the 10 groups identified were related to "neonatal nursing and practice guideline," "infant or pediatric and terminal care," and "family, aged, and nurse-patient relations," respectively. This study can promote a systematic understanding of communication in intensive care units by identifying topic networks. Future studies are needed to conduct large prospective cohort studies and randomized controlled trials to verify the effects of patient-centered communication in intensive care units on patient outcomes, such as length of hospital stay and mortality.

The objective of the Communications Technology Program is to enable data transmission to and from low Earth orbit, geostationary orbit, and solar and deep space missions. This can be achieved by maintaining an effective, balances effort in basic, applied, and demonstration prototype communications technology through work in theory, experimentation, and components. The program consists of three major research and development discipline areas which are: microwave and millimeter wave tube components; solid state monolithic integrated circuit; and free space laser communications components and devices. The research ranges from basic research in surface physics (to study the mechanisms of surface degradation from under high temperature and voltage operating conditions which impacts cathode tube reliability and lifetime) to generic research on the dynamics of electron beams and circuits (for exploitation in various micro- and millimeter wave tube devices). Work is also performed on advanced III-V semiconductor materials and devices for use in monolithic integrated analog circuits (used in adaptive, programmable phased arrays for microwave antenna feeds and receivers) - on the use of electromagnetic theory in antennas and on technology necessary for eventual employment of lasers for free space communications for future low earth, geostationary, and deep space missions requiring high data rates with corresponding directivity and reliability.

McWhirter, Jennifer E; Hoffman-Goetz, Laurie

2014-01-01

Visual images increase attention, comprehension, and recall of health information and influence health behaviors. Health communication campaigns on skin cancer and tanning often use visual images, but little is known about how such images are selected or evaluated. A systematic review of peer-reviewed, published literature on skin cancer and tanning was conducted to determine (a) what visual communication theories were used, (b) how visual images were evaluated, and (c) how visual images were used in the research studies. Seven databases were searched (PubMed/MEDLINE, EMBASE, PsycINFO, Sociological Abstracts, Social Sciences Full Text, ERIC, and ABI/INFORM) resulting in 5,330 citations. Of those, 47 met the inclusion criteria. Only one study specifically identified a visual communication theory guiding the research. No standard instruments for assessing visual images were reported. Most studies lacked, to varying degrees, comprehensive image description, image pretesting, full reporting of image source details, adequate explanation of image selection or development, and example images. The results highlight the need for greater theoretical and methodological attention to visual images in health communication research in the future. To this end, the authors propose a working definition of visual health communication.

The Stakeholder Model of voice research: Acknowledging barriers to human rights of all stakeholders in a communicative exchange.

PubMed

Madill, Catherine; Warhurst, Samantha; McCabe, Patricia

2018-02-01

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.

With the increasing market in laser medicine and surgery it is well to plan ahead so that there will be increasing production. For the concept of so-called laser biostimulation with various low output laser systems there is much need for well controlled studies to avoid discrediting all of laser medicine. There is great potential for the future in laser instrumentation for heart disease, cancer research, diagnoses and treatment, all fields of surgery, and in perinatology. Also, laser communications and information handling can make for deliverance of better health care. It is well to open up better lines of communication between laser industry and modern medicine.

Brief Communication: The dark side of risk and crisis communication: legal conflicts and responsibility allocation

NASA Astrophysics Data System (ADS)

Scolobig, A.

2015-06-01

Inadequate, misinterpreted, or missing risk and crisis communication may be a reason for practitioners, and sometimes science advisors, to become the subjects of criminal investigations. This work discusses the legal consequences of inadequate risk communication in these situations. After presenting some cases, the discussion focuses on three critical issues: the development of effective communication protocols; the role, tasks, and responsibilities of science advisors; and the collateral effects of practitioners' defensive behaviours. For example, if the avoidance of personal liability becomes a primary objective for practitioners, it may clash with other objectives, such as the protection of vulnerable communities or the transparency of decision making. The conclusion presents some ideas for future research on the legal aspects of risk communication.

Nonmedical interventions for children with ASD: recommended guidelines and further research needs.

2012-11-01

To use the findings of a systematic review of scientific evidence to develop consensus guidelines on nonmedical interventions that address cognitive function and core deficits in children with autism spectrum disorders (ASDs) and to recommend priorities for future research. The guidelines were developed by a Technical Expert Panel (TEP) consisting of practitioners, researchers, and parents. A systematic overview of research findings was presented to the TEP; guideline statements were drafted, discussed, debated, edited, reassessed, and presented for formal voting. The strength of evidence of efficacy varied by intervention type from insufficient to moderate. There was some evidence that greater intensity of treatment (hours per week) and greater duration (in months) led to better outcomes. The TEP agreed that children with ASD should have access to at least 25 hours per week of comprehensive intervention to address social communication, language, play skills, and maladaptive behavior. They agreed that applied behavioral analysis, integrated behavioral/developmental programs, the Picture Exchange Communication System, and various social skills interventions have shown efficacy. Based on identified gaps, they recommend that future research focus on assessment and monitoring of outcomes, addressing the needs of pre/nonverbal children and adolescents, and identifying the most effective strategies, dose, and duration to improve specific core deficits. The creation of treatment guidelines and recommendations for future research represents an effort by leading experts to improve access to services for children with ASDs while acknowledging that the research evidence has many gaps.

The National Diabetes Education Program (NDEP) was established to translate findings from diabetes research studies into clinical and public health practice. Over 20 years, NDEP has built a program with partnership engagement that includes science-based resources for multiple population and stakeholder audiences. Throughout its history, NDEP has developed strategies and messages based on communication research and relied on established behavior change models from health education, communication, and social marketing. The program's success in continuing to engage diverse partners after 20 years has led to time-proven and high-quality resources that have been sustained. Today, NDEP maintains a national repository of diabetes education tools and resources that are high quality, science- and audience-based, culturally and linguistically appropriate, and available free of charge to a wide variety of audiences. This review looks back and describes NDEP's evolution in transforming and communicating diabetes management and type 2 diabetes prevention strategies through partnerships, campaigns, educational resources, and tools and identifies future opportunities and plans. © 2018 by the American Diabetes Association.

Understanding tailoring in communicating about health

PubMed Central

Hawkins, Robert P.; Kreuter, Matthew; Resnicow, Kenneth; Fishbein, Martin; Dijkstra, Arie

2011-01-01

‘Tailoring’ refers to any of a number of methods for creating communications individualized for their receivers, with the expectation that this individualization will lead to larger intended effects of these communications. Results so far have been generally positive but not consistently so, and this paper seeks to explicate tailoring to help focus future research. Tailoring involves either or both of two classes of goals (enhancing cognitive preconditions for message processing and enhancing message impact through modifying behavioral determinants of goal outcomes) and employs strategies of personalization, feedback and content matching. These goals and strategies intersect in a 2 × 3 matrix in which some strategies and their component tactics match better to some goals than to others. The paper illustrates how this framework can be systematically applied in generating research questions and identifying appropriate study designs for tailoring research. PMID:18349033

Reputation, relationships, risk communication, and the role of trust in the prevention and control of communicable disease: a review.

PubMed

Cairns, Georgina; de Andrade, Marisa; MacDonald, Laura

2013-01-01

Population-level compliance with health protective behavioral advice to prevent and control communicable disease is essential to optimal effectiveness. Multiple factors affect perceptions of trustworthiness, and trust in advice providers is a significant predeterminant of compliance. While competency in assessment and management of communicable disease risks is critical, communications competency may be equally important. Organizational reputation, quality of stakeholder relationships and risk information provision strategies are trust moderating factors, whose impact is strongly influenced by the content, timing and coordination of communications. This article synthesizes the findings of 2 literature reviews on trust moderating communications and communicable disease prevention and control. We find a substantial evidence base on risk communication, but limited research on other trust building communications. We note that awareness of good practice historically has been limited although interest and the availability of supporting resources is growing. Good practice and policy elements are identified: recognition that crisis and risk communications require different strategies; preemptive dialogue and planning; evidence-based approaches to media relations and messaging; and building credibility for information sources. Priority areas for future research include process and cost-effectiveness evaluation and the development of frameworks that integrate communication and biomedical disease control and prevention functions, conceptually and at scale.

The dark side of risk and crisis communication: legal conflicts and responsibility allocation

NASA Astrophysics Data System (ADS)

Scolobig, A.

2015-04-01

Inadequate, misinterpreted or missing risk and crisis communication may be a reason for practitioners, and sometimes even science advisors, to become subjects of criminal charges. This work discusses the legal consequences of communication. After presenting some cases, the discussion focuses on three critical issues: the development of effective communication protocols; the role, tasks and responsibilities of science advisors; and the collateral effects of practitioners' defensive behaviours. For example, if the avoidance of personal liability becomes a primary objective for practitioners, it may clash with other objectives, such as the protection of vulnerable communities or the transparency of decision-making. The conclusion presents some ideas for future research on the legal aspects of risk communication.

Users of Japanese communications satellite are presented.

Physician communication in the operating room: expanding application of face-negotiation theory to the health communication context.

PubMed

Kirschbaum, Kristin

2012-01-01

Communication variables that are associated with face-negotiation theory were examined in a sample of operating-room physicians. A survey was administered to anesthesiologists and surgeons at a teaching hospital in the southwestern United States to measure three variables commonly associated with face-negotiation theory: conflict-management style, face concern, and self-construal. The survey instrument that was administered to physicians includes items that measured these three variables in previous face-negotiation research with slight modification of item wording for relevance in the medical setting. The physician data were analyzed using confirmatory factor analysis, Pearson's correlations, and t-tests. Results of this initial investigation showed that variables associated with face-negotiation theory were evident in the sample physician population. In addition, the correlations were similar among variables in the medical sample as those found in previous face-negotiation research. Finally, t-tests suggest variance between anesthesiologists and surgeons on specific communication variables. These findings suggest three implications that warrant further investigation with expanded sample size: (1) An intercultural communication theory and instrument can be utilized for health communication research; (2) as applied in a medical context, face-negotiation theory can be expanded beyond traditional intercultural communication boundaries; and (3) theoretically based communication structures applied in a medical context could help explain physician miscommunication in the operating room to assist future design of communication training programs for operating-room physicians.

Motor development and motor resonance difficulties in autism: relevance to early intervention for language and communication skills

PubMed Central

McCleery, Joseph P.; Elliott, Natasha A.; Sampanis, Dimitrios S.; Stefanidou, Chrysi A.

2013-01-01

Research suggests that a sub-set of children with autism experience notable difficulties and delays in motor skills development, and that a large percentage of children with autism experience deficits in motor resonance. These motor-related deficiencies, which evidence suggests are present from a very early age, are likely to negatively affect social-communicative and language development in this population. Here, we review evidence for delayed, impaired, and atypical motor development in infants and children with autism. We then carefully review and examine the current language and communication-based intervention research that is relevant to motor and motor resonance (i.e., neural “mirroring” mechanisms activated when we observe the actions of others) deficits in children with autism. Finally, we describe research needs and future directions and developments for early interventions aimed at addressing the speech/language and social-communication development difficulties in autism from a motor-related perspective.

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.

Parents' Verbal Communication and Childhood Anxiety: A Systematic Review.

PubMed

Percy, Ray; Creswell, Cathy; Garner, Matt; O'Brien, Doireann; Murray, Lynne

2016-03-01

Parents' verbal communication to their child, particularly the expression of fear-relevant information (e.g., attributions of threat to the environment), is considered to play a key role in children's fears and anxiety. This review considers the extent to which parental verbal communication is associated with child anxiety by examining research that has employed objective observational methods. Using a systematic search strategy, we identified 15 studies that addressed this question. These studies provided some evidence that particular fear-relevant features of parental verbal communication are associated with child anxiety under certain conditions. However, the scope for drawing reliable, general conclusions was limited by extensive methodological variation between studies, particularly in terms of the features of parental verbal communication examined and the context in which communication took place, how child anxiety was measured, and inconsistent consideration of factors that may moderate the verbal communication-child anxiety relationship. We discuss ways in which future research can contribute to this developing evidence base and reduce further methodological inconsistency so as to inform interventions for children with anxiety problems.

Designing augmentative and alternative communication applications: the results of focus groups with speech-language pathologists and parents of children with autism spectrum disorder.

Boster, Jamie B; McCarthy, John W

2018-05-01

The purpose of this study was to gain insight from speech-language pathologists (SLPs) and parents of children with autism spectrum disorder (ASD) regarding appealing features of augmentative and alternative communication (AAC) applications. Two separate 1-hour focus groups were conducted with 8 SLPs and 5 parents of children with ASD to identify appealing design features of AAC Apps, their benefits and potential concerns. Participants were shown novel interface designs for communication mode, play mode and incentive systems. Participants responded to poll questions and provided benefits and drawbacks of the features as part of structured discussion. SLPs and parents identified a range of appealing features in communication mode (customization, animation and colour-coding) as well as in play mode (games and videos). SLPs preferred interfaces that supported motor planning and instruction while parents preferred those features such as character assistants that would appeal to their child. Overall SLPs and parents agreed on features for future AAC Apps. SLPs and parents have valuable input in regards to future AAC app design informed by their experiences with children with ASD. Both groups are key stakeholders in the design process and should be included in future design and research endeavors. Implications for Rehabilitation AAC applications for the iPad are often designed based on previous devices without consideration of new features. Ensuring the design of new interfaces are appealing and beneficial for children with ASD can potentially further support their communication. This study demonstrates how key stakeholders in AAC including speech language pathologists and parents can provide information to support the development of future AAC interface designs. Key stakeholders may be an untapped resource in the development of future AAC interfaces for children with ASD.

Factors Influencing Postsecondary STEM Students' Views of the Public Communication of an Emergent Technology: a Cross-National Study from Five Universities

Recent efforts in the science education community have highlighted the need to integrate research and theory from science communication research into more general science education scholarship. These synthesized research perspectives are relatively novel but serve an important need to better understand the impacts that the advent of rapidly emerging technologies will have on a new generation of scientists and engineers including their formal communication with engaged citizenry. This cross-national study examined postsecondary science and engineering students' ( n = 254 from five countries: Austria, Finland, France, Israel, and USA) perspectives on the role of science communication in their own formal science and engineering education. More broadly, we examined participants' understanding of their perceived responsibilities of communicating science and engineering to the general public when an issue contains complex social and ethical implications (SEI). The study is contextualized in the emergent technology of nanotechnology for which SEI are of particular concern and for which the general public often perceives conflicting risks and benefits. Findings indicate that student participants' hold similar views on the need for their own training in communication as future scientists and engineers. When asked about the role that ethics and risk perception plays in research, development, and public communication of nanotechnology, participants demonstrate similar trajectories of perspectives that are, however, often anchored in very different levels of beginning concern. Results are discussed in the context of considerations for science communication training within formal science education curricula globally.

"I'll never forget this": evaluating a pilot workshop in effective communication for dental students.

This study evaluated a pilot workshop for teaching communication skills to dental students. The methodology is based on an experiential learning approach, the use of realistic clinical scenarios, simulated patients, and an integrated teaching team of both educational researchers and dentists. Furthermore, the methodology was adapted for short workshops, which is thought to offer better possibilities for frequent and effective training of communication skills throughout the curriculum. The work-shop was piloted with groups of six to ten students from the sixth and tenth semesters (n=94). Results show that the majority of students found the tasks meaningful and well aligned with how they perceived their future profession as dentists. Most students also thought that they learned from the task. An interesting finding is that students not only found it instructive to practice how to communicate in authentic situations, but that they generally found the workshop to be thought-provoking while at the same time providing structure and intellectual tools for the future. A possible explanation for this finding is the sharing of explicit criteria for high-quality communication.

Insect Cuticular Hydrocarbons as Dynamic Traits in Sexual Communication

PubMed Central

Ingleby, Fiona C.

2015-01-01

Recent research has demonstrated extensive within-species variation in pheromone expression in insect species, contrary to the view that pheromones are largely invariant within species. In fact, many studies on insect cuticular hydrocarbons (CHCs) show that pheromones can be highly dynamic traits that can express significant short-term plasticity across both abiotic and social environments. It is likely that this variability in CHC expression contributes to their important role in sexual signaling and mate choice. In this review, I discuss CHC plasticity and how this might influence sexual communication. I also highlight two important avenues for future research: examining plasticity in how individuals respond to CHC signals, and testing how sexual communication varies across abiotic and social environments.

A new generation of IC based beam steering devices for free-space optical communication

NASA Astrophysics Data System (ADS)

Bedi, Vijit

Free Space Optical (FSO) communication has tremendously advanced within the last decade to meet the ever increasing demand for higher communication bandwidth. Advancement in laser technology since its invention in the 1960's [1] attracted them to be the dominant source in FSO communication modules. The future of FSO systems lay in implementing semiconductor lasers due to their small size, power efficiency and mass fabrication abilities. In the near future, these systems are very likely to be used in space and ground based applications and revolutionary beam steering technologies will be required for distant communications in free-space. The highly directional characteristic inherent to a laser beam challenges and calls for new beam pointing and steering technologies for such type of communication. In this dissertation, research is done on a novel FSO communication device based on semiconductor lasers for high bandwidth communication. The "Fly eye transceiver" is an extremely wide steering bandwidth, completely non-mechanical FSO laser communication device primarily designed to replace traditional mechanical beam steering optical systems. This non-mechanical FSO device possesses a full spherical steering range and a very high tracking bandwidth. Inspired by the evolutionary model of a fly's eye, the full spherical steering range is assured by electronically controlled switching of its sub-eyes. Non mechanical technologies used in the past for beam steering such as acousto-optic Bragg cells, liquid crystal arrays or piezoelectric elements offer the wide steering bandwidth and fast response time, but are limited in their angular steering range. Mechanical gimbals offer a much greater steering range but face a much slower response time or steering bandwidth problem and often require intelligent adaptive controls with bulky driver amplifiers to feed their actuators. As a solution to feed both the fast and full spherical steering, the Fly-eye transceiver is studied as part of my PhD work. The design tool created for the research of the fly eye is then used to study different applications that may be implemented with the concept. Research is done on the mathematical feasibility, modeling, design, application of the technology, and its characterization in a simulation environment. In addition, effects of atmospheric turbulence on beam propagation in free space, and applying data security using optical encryption are also researched.

This report describes the process, findings, and recommendations of the second of three phases of the Future Communications Study (FCS) technology investigation conducted by NASA Glenn Research Center and ITT Advanced Engineering & Sciences Division for the Federal Aviation Administration (FAA). The FCS is a collaborative research effort between the FAA and Eurocontrol to address frequency congestion and spectrum depletion for safety critical airground communications. The goal of the technology investigation is to identify technologies that can support the longterm aeronautical mobile communication operating concept. A derived set of evaluation criteria traceable to the operating concept document is presented. An adaptation of the analytical hierarchy process is described and recommended for selecting candidates for detailed evaluation. Evaluations of a subset of technologies brought forward from the prescreening process are provided. Five of those are identified as candidates with the highest potential for continental airspace solutions in L-band (P-34, W-CDMA, LDL, B-VHF, and E-TDMA). Additional technologies are identified as best performers in the unique environments of remote/oceanic airspace in the satellite bands (Inmarsat SBB and a custom satellite solution) and the airport flight domain in C-band (802.16e). Details of the evaluation criteria, channel models, and the technology evaluations are provided in appendixes.

A paper describes the Space- to-Space Communications System (SSCS) Software- Defined Radio (SDR) research project to determine the most appropriate method for creating flexible and reconfigurable radios to implement wireless communications channels for space vehicles so that fewer radios are required, and commonality in hardware and software architecture can be leveraged for future missions. The ability to reconfigure the SDR through software enables one radio platform to be reconfigured to interoperate with many different waveforms. This means a reduction in the number of physical radio platforms necessary to support a space mission s communication requirements, thus decreasing the total size, weight, and power needed for a mission.

Using high-performance networks to enable computational aerosciences applications

NASA Technical Reports Server (NTRS)

Johnson, Marjory J.

1992-01-01

One component of the U.S. Federal High Performance Computing and Communications Program (HPCCP) is the establishment of a gigabit network to provide a communications infrastructure for researchers across the nation. This gigabit network will provide new services and capabilities, in addition to increased bandwidth, to enable future applications. An understanding of these applications is necessary to guide the development of the gigabit network and other high-performance networks of the future. In this paper we focus on computational aerosciences applications run remotely using the Numerical Aerodynamic Simulation (NAS) facility located at NASA Ames Research Center. We characterize these applications in terms of network-related parameters and relate user experiences that reveal limitations imposed by the current wide-area networking infrastructure. Then we investigate how the development of a nationwide gigabit network would enable users of the NAS facility to work in new, more productive ways.

Effective communication tools to engage Torres Strait Islanders in scientific research

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.

Applying Weick's model of organizing to health care and health promotion: highlighting the central role of health communication.

PubMed

Kreps, Gary L

2009-03-01

Communication is a crucial process in the effective delivery of health care services and the promotion of public health. However, there are often tremendous complexities in using communication effectively to provide the best health care, direct the adoption of health promoting behaviors, and implement evidence-based public health policies and practices. This article describes Weick's model of organizing as a powerful theory of social organizing that can help increase understanding of the communication demands of health care and health promotion. The article identifies relevant applications from the model for health communication research and practice. Weick's model of organizing is a relevant and heuristic theoretical perspective for guiding health communication research and practice. There are many potential applications of this model illustrating the complexities of effective communication in health care and health promotion. Weick's model of organizing can be used as a template for guiding both research and practice in health care and health promotion. The model illustrates the important roles that communication performs in enabling health care consumers and providers to make sense of the complexities of modern health care and health promotion, select the best strategies for responding effectively to complex health care and health promotion situations, and retain relevant information (develop organizational intelligence) for guiding future responses to complex health care and health promotion challenges.

Stroke patients communicating their healthcare needs in hospital: a study within the ICF framework.

PubMed

O'Halloran, Robyn; Worrall, Linda; Hickson, Louise

2012-01-01

Previous research has identified that many patients admitted into acute hospital stroke units have communication-related impairments such as hearing, vision, speech, language and/or cognitive communicative impairment. However, no research has identified how many patients in acute hospital stroke units have difficulty actually communicating their healthcare needs. The World Health Organization's International Classification of Functioning, Disability and Health (ICF) conceptualizes difficulty communicating about healthcare needs as a type of activity limitation, within the Activity and Participation component. The ICF proposes that activity limitation can be measured in four different ways. The first aim of this research was to measure a patient's difficulty communicating his or her healthcare needs, that is, activity limitation, in two of the four ways suggested by the ICF when interacting with healthcare providers. The second aim was to investigate whether communication-related impairments in hearing, vision, speech, language and/or cognitive communicative impairment predict difficulty communicating healthcare needs, measured in these ways. A total of 65 patients consecutively admitted into two acute hospital stroke units in Melbourne, Australia, who consented to this research participated in this study. Early in their admission participants were screened for hearing, vision, speech, language and cognitive communicative impairment. Participants were also assessed for difficulty communicating about healthcare needs in two ways proposed by the ICF: 'capacity with assistance' and 'performance'. Relationships between communication-related impairment and both capacity with assistance and performance were explored through Spearman's correlations and binary logistic regression. A total of 87% of patients had one or more communication-related impairments. Half of the patients (51%) had difficulty communicating their healthcare needs when assessed in terms of capacity with assistance. Slightly more patients (55%) were observed to have difficulty communicating their healthcare needs when assessed in terms of performance. More severe vision, speech, language and cognitive communicative impairment were significantly associated with more severe difficulty communicating healthcare needs. About half of the stroke patients admitted into acute hospital stroke units had difficulty communicating their healthcare needs. Patients with more severe communication-related impairments had more severe difficulty communicating their healthcare needs. Future research is needed to understand the other factors that influence communication between people with communication disabilities and their healthcare providers in acute hospital settings. © 2012 Royal College of Speech and Language Therapists.

Effective communication is a requirement in the teamwork necessary for improved coordination to deliver patient-centered, value-based cancer care. Communication is particularly important when care providers are geographically distributed or work across organizations. We review organizational and teams research on communication to highlight psychological safety as a key determinant of high-quality communication within teams. We first present the concept of psychological safety, findings about its communication effects for teamwork, and factors that affect it. We focus on five factors applicable to cancer care delivery: familiarity, clinical hierarchy-related status differences, geographic dispersion, boundary spanning, and leader behavior. To illustrate how these factors facilitate or hinder psychologically safe communication and teamwork in cancer care, we review the case of a patient as she experiences the treatment-planning process for early-stage breast cancer in a community setting. Our analysis is summarized in a key principle: Teamwork in cancer care requires high-quality communication, which depends on psychological safety for all team members, clinicians and patients alike. We conclude with a discussion of the implications of psychological safety in clinical care and suggestions for future research.

The Communications Center's portfolio covers areas such as marketing, contacts, distribution of information, sales activities and collection of bills by telephone (encashment). A special emphasis is Customer Care Management (Customer Relationship Management) to the patient and his caregivers (relatives), the customers, especially the physicians who send their patients to the hospital and the hospital doctor. By providing communication centers, the hospital would be able to improve the communication with the G.P.s, and identify the wishes and requirements more accurately and easily from the beginning. Dealing effectively with information and communication is already also of special importance for hospital doctors today. One can assume that the demands on doctors in this respect will become even more complex in the future. Doctors who are involved in scientific research are of course fully aware of the growing importance of the Internet with its new information and communication channels. Therefore analysing the current situation, the demands on a future information management system can be formulated: A system that will help doctors to avoid dealing with little goal-oriented information and thus setting up effective communication channels; an information system which is multi-media oriented towards the interests and needs of the patients and patient's relatives and which is further developed continually and directly by those involved.

Meta-analysis of surgical safety checklist effects on teamwork, communication, morbidity, mortality, and safety.

Lyons, Vanessa E; Popejoy, Lori L

2014-02-01

The purpose of this study is to examine the effectiveness of surgical safety checklists on teamwork, communication, morbidity, mortality, and compliance with safety measures through meta-analysis. Four meta-analyses were conducted on 19 studies that met the inclusion criteria. The effect size of checklists on teamwork and communication was 1.180 (p = .003), on morbidity and mortality was 0.123 (p = .003) and 0.088 (p = .001), respectively, and on compliance with safety measures was 0.268 (p < .001). The results indicate that surgical safety checklists improve teamwork and communication, reduce morbidity and mortality, and improve compliance with safety measures. This meta-analysis is limited in its generalizability based on the limited number of studies and the inclusion of only published research. Future research is needed to examine possible moderating variables for the effects of surgical safety checklists.

2014-01-01

Objective Condom use is critical for the health of sexually active adolescents, and yet many adolescents fail to use condoms consistently. One interpersonal factor that may be key to condom use is sexual communication between sexual partners; however, the association between communication and condom use has varied considerably in prior studies of youth. The purpose of this meta-analysis was to synthesize the growing body of research linking adolescents’ sexual communication to condom use, and to examine several moderators of this association. Methods A total of 41 independent effect sizes from 34 studies with 15,046 adolescent participants (Mage=16.8, age range=12–23) were meta-analyzed. Results Results revealed a weighted mean effect size of the sexual communication-condom use relationship of r = .24, which was statistically heterogeneous (Q=618.86, p<.001, I2 =93.54). Effect sizes did not differ significantly by gender, age, recruitment setting, country of study, or condom measurement timeframe; however, communication topic and communication format were statistically significant moderators (p<.001). Larger effect sizes were found for communication about condom use (r = .34) than communication about sexual history (r = .15) or general safer sex topics (r = .14). Effect sizes were also larger for communication behavior formats (r = .27) and self-efficacy formats (r = .28), than for fear/concern (r = .18), future intention (r = .15), or communication comfort (r = −.15) formats. Conclusions Results highlight the urgency of emphasizing communication skills, particularly about condom use, in HIV/STI prevention work for youth. Implications for the future study of sexual communication are discussed. PMID:25133828

Several courageous plans regarding future human space exploration have been proposed. Both main future targets, ESA's Moon village, as well as journey to Mars represent huge challenge for humans. Appropriate research on psychological aspects of humans in extreme conditions is needed. Analogue simulations represent valuable source of information that help us to understand how to provide an adequate support to astronauts in specific conditions of isolation and limited resources. The psychosocial investigation was designed to builds on combination of several methods based on subjective as well as objective assessments, namely observation, sociomapping, content analysis of interviews etc. Research on several simulations provided lessons learned and various insights. The attention was paid particularly to the interpersonal interactions among crew members, intragroup as well as intergroup communication, cooperation, and performance. This comprehensive approach enables early detection of hidden structures and potential insufficiencies of an astronaut team. The sociomapping of interpersonal communication as well as analysis of interviews with participants revealed insufficiencies especially in communication between the analogue astronauts and mission control. Another important finding was gain by investigation of the relationship between the astronaut crew and mission control. Astronauts low trust to mission control can have a great negative impact to the performance and well-being of astronauts. The findings of the psychosocial studies are very important for designing astronaut training and planning future mission.

According to the prediction, in the next 10 years the wireless data traffic will be increased by 500-1000 times. Not only the wireless data traffic will be increased exponentially, and the demand for diversified traffic will be increased. Higher requirements for future mobile wireless communication system had brought huge market space for satellite communication system. At the same time, the space information networks had been greatly developed with the depth of human exploration of space activities, the development of space application, the expansion of military and civilian application. The core of spatial information networks is the satellite communication. The dissertation presented the communication system architecture, the communication protocol, the routing strategy, switch scheduling algorithm and the handoff strategy based on the satellite communication system. We built the simulation platform of the LEO satellites networks and simulated the key technology using OPNET.

Building Interdisciplinary Research and Communication Skills in the Agricultural and Climate Sciences

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 (http://www.cals.uidaho.edu/toolbox/) 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 future projects involving graduate student training.

Communicating science in social settings.

Scheufele, Dietram A

2013-08-20

This essay examines the societal dynamics surrounding modern science. It first discusses a number of challenges facing any effort to communicate science in social environments: lay publics with varying levels of preparedness for fully understanding new scientific breakthroughs; the deterioration of traditional media infrastructures; and an increasingly complex set of emerging technologies that are surrounded by a host of ethical, legal, and social considerations. Based on this overview, I discuss four areas in which empirical social science helps clarify intuitive but sometimes faulty assumptions about the social-level mechanisms of science communication and outline an agenda for bench and social scientists--driven by current social-scientific research in the field of science communication--to guide more effective communication efforts at the societal level in the future.

Goldsmith, Joy; Wittenberg-Lyles, Elaine; Shaunfield, Sara; Sanchez-Reilly, Sandra

2011-06-01

Limited attention to palliative care communication training is offered to medical students. In this work, we pursued unfolding case responses and what they indicated about student tendencies to use palliative care communication as well as what medical students can learn from their own reflective practice about palliative care. Findings showed an overwhelming trend for students to avoid palliative care communication or inclusion of topics including advance directives, place of care, family support, and dying. Instead, students relied heavily on the SPIKES protocol, communication that was strategically vague and ambiguous, and discussions that centered on specialty care and referral. In reflecting on their own case study responses, students noted an absence of direct communication about prognosis, no coordination of care, late hospice entry, and patient pain resulting from communication inefficacies. Future research should focus on the development of formal and adaptive curriculum structures to address these communication needs.

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.

Vitale Shreve, Kristyn R; Udell, Monique A R

2015-11-01

The domestic cat (Felis silvestris catus) has shared an intertwined existence with humans for thousands of years, living on our city streets and in our homes. Yet, little scientific research has focused on the cognition of the domestic cat, especially in comparison with human's other companion, the domestic dog (Canis lupus familiaris). This review surveys the current status of several areas of cat cognition research including perception, object permanence, memory, physical causality, quantity and time discrimination, cats' sensitivity to human cues, vocal recognition and communication, attachment bonds, personality, and cognitive health. Although interest in cat cognition is growing, we still have a long way to go until we have an inclusive body of research on the subject. Therefore, this review also identifies areas where future research must be conducted. In addition to the scientific value of future work in this area, future research on cat cognition could have an important influence on the management and welfare of pet and free-roaming cats, leading to improved human-cat interactions.

Family-centered services for children with complex communication needs: the practices and beliefs of school-based speech-language pathologists.

PubMed

Mandak, Kelsey; Light, Janice

2018-06-01

This study used an online focus group to examine the beliefs and practices of school-based speech-language pathologists (SLPs) who served children with complex communication needs regarding their provision of family-centered services. Participants revealed that despite their desire for family involvement and reported beliefs in the importance of family-centered services, there were barriers in place that often limited family-centered service provision. Across the SLPs, many were dissatisfied with their current provision of family-centered services. The SLPs varied in their reported practices, with some reporting family-centered services and others, professional-centered services. Future research is recommended in order to investigate which factors contribute to the variation among SLPs and how the variation impacts children who require augmentative and alternative communication (AAC) and their families. Potential clinical implications for in-service and pre-service SLPs are discussed to improve future family-centered AAC services.

Branley, Dawn B; Covey, Judith

2017-01-01

Objectives: To compare how people communicate about eating disorders on two popular social media platforms - Twitter and Tumblr. Materials and Methods: Thematic analysis was conducted to characterize the types of communications posted, and a content analysis was undertaken of between-platform differences. Results: Three types of content (pro-ana, anti-ana, and pro-recovery) were posted on each platform. Overall, across both platforms, extreme pro-ana posts were in the minority compared to anti-ana and pro-recovery. Pro-ana posts (including 'thinspiration') were more common on Twitter than Tumblr, whereas anti-ana and pro-recovery posts were more common on Tumblr. Conclusion: The findings have implications for future research and health care relating to the treatment and prevention of eating disorders. Developers of future interventions targeting negative pro-ana content should remain aware of the need to avoid any detrimental impact on positive online support.

This document is being provided as part of ITT's NASA Glenn Research Center Aerospace Communication Systems Technical Support (ACSTS) contract NNC05CA85C, Task 7: "New ATM Requirements--Future Communications, C-Band and L-Band Communications Standard Development." The proposed future C-band (5091- to 5150-MHz) airport surface communication system, referred to as the Aeronautical Mobile Airport Communications System (AeroMACS), is anticipated to increase overall air-to-ground data communications systems capacity by using a new spectrum (i.e., not very high frequency (VHF)). Although some critical services could be supported, AeroMACS will also target noncritical services, such as weather advisory and aeronautical information services as part of an airborne System Wide Information Management (SWIM) program. AeroMACS is to be designed and implemented in a manner that will not disrupt other services operating in the C-band. This report defines the AeroMACS concepts of use, high-level system requirements, and architecture; the performance of supporting system analyses; the development of AeroMACS test and demonstration plans; and the establishment of an operational AeroMACS capability in support of C-band aeronautical data communications standards to be advanced in both international (International Civil Aviation Organization, ICAO) and national (RTCA) forums. This includes the development of system parameter profile recommendations for AeroMACS based on existing Institute of Electrical and Electronics Engineering (IEEE) 802.16e- 2009 standards

Guidelines for Reporting Articles on Psychiatry and Heart rate variability (GRAPH): recommendations to advance research communication

Quintana, D S; Alvares, G A; Heathers, J A J

2016-01-01

The number of publications investigating heart rate variability (HRV) in psychiatry and the behavioral sciences has increased markedly in the last decade. In addition to the significant debates surrounding ideal methods to collect and interpret measures of HRV, standardized reporting of methodology in this field is lacking. Commonly cited recommendations were designed well before recent calls to improve research communication and reproducibility across disciplines. In an effort to standardize reporting, we propose the Guidelines for Reporting Articles on Psychiatry and Heart rate variability (GRAPH), a checklist with four domains: participant selection, interbeat interval collection, data preparation and HRV calculation. This paper provides an overview of these four domains and why their standardized reporting is necessary to suitably evaluate HRV research in psychiatry and related disciplines. Adherence to these communication guidelines will help expedite the translation of HRV research into a potential psychiatric biomarker by improving interpretation, reproducibility and future meta-analyses.

Schmidt, David; Kurtz, Megan; Davidson, Stuart

2017-01-01

District advisors in five allied health disciplines were introduced in a local health district in rural Australia in 2013. These strategic leadership roles provide support to clinicians and managers. As there is little research exploring allied health leadership models from a strategic and operational perspective, the coordinated commencement of these roles provided opportunity to study the creation of this leadership structure. Four advisors participated in this action research study which used focus groups and program logic processes to explore the inputs, outputs, barriers, outcomes to date, and preferred future outcomes of the leadership model. A purpose-built questionnaire was sent to 134 allied health clinicians or managers with questionnaire responses used by advisors to visualise the leadership model. Advisors prioritised policy development, representing the profession outside the organisation, and supporting department managers, whilst clinicians prioritised communication and connection-building within the organisation. Outcomes of the leadership model included connection, coordination, and advocacy for clinicians. Future preferred outcomes included increased strategic and workforce planning. Barriers included limited time, a widespread workforce and limited resourcing. Instituting a leadership model improved communication, cohesion, and coordination within the organisation. Future increases in workforce planning and coordination are limited by advisor capacity and competing workloads.

Communicating Numerical Risk: Human Factors That Aid Understanding in Health Care

Brust-Renck, Priscila G.; Royer, Caisa E.; Reyna, Valerie F.

2014-01-01

In this chapter, we review evidence from the human factors literature that verbal and visual formats can help increase the understanding of numerical risk information in health care. These visual representations of risk are grounded in empirically supported theory. As background, we first review research showing that people often have difficulty understanding numerical risks and benefits in health information. In particular, we discuss how understanding the meanings of numbers results in healthier decisions. Then, we discuss the processes that determine how communication of numerical risks can enhance (or degrade) health judgments and decisions. Specifically, we examine two different approaches to risk communication: a traditional approach and fuzzy-trace theory. Applying research on the complications of understanding and communicating risks, we then highlight how different visual representations are best suited to communicating different risk messages (i.e., their gist). In particular, we review verbal and visual messages that highlight gist representations that can better communicate health information and improve informed decision making. This discussion is informed by human factors theories and methods, which involve the study of how to maximize the interaction between humans and the tools they use. Finally, we present implications and recommendations for future research on human factors in health care. PMID:24999307

There is currently a lack of information about the uses, benefits, and limitations of social media for health communication among the general public, patients, and health professionals from primary research. To review the current published literature to identify the uses, benefits, and limitations of social media for health communication among the general public, patients, and health professionals, and identify current gaps in the literature to provide recommendations for future health communication research. This paper is a review using a systematic approach. A systematic search of the literature was conducted using nine electronic databases and manual searches to locate peer-reviewed studies published between January 2002 and February 2012. The search identified 98 original research studies that included the uses, benefits, and/or limitations of social media for health communication among the general public, patients, and health professionals. The methodological quality of the studies assessed using the Downs and Black instrument was low; this was mainly due to the fact that the vast majority of the studies in this review included limited methodologies and was mainly exploratory and descriptive in nature. Seven main uses of social media for health communication were identified, including focusing on increasing interactions with others, and facilitating, sharing, and obtaining health messages. The six key overarching benefits were identified as (1) increased interactions with others, (2) more available, shared, and tailored information, (3) increased accessibility and widening access to health information, (4) peer/social/emotional support, (5) public health surveillance, and (6) potential to influence health policy. Twelve limitations were identified, primarily consisting of quality concerns and lack of reliability, confidentiality, and privacy. Social media brings a new dimension to health care as it offers a medium to be used by the public, patients, and health professionals to communicate about health issues with the possibility of potentially improving health outcomes. Social media is a powerful tool, which offers collaboration between users and is a social interaction mechanism for a range of individuals. Although there are several benefits to the use of social media for health communication, the information exchanged needs to be monitored for quality and reliability, and the users' confidentiality and privacy need to be maintained. Eight gaps in the literature and key recommendations for future health communication research were provided. Examples of these recommendations include the need to determine the relative effectiveness of different types of social media for health communication using randomized control trials and to explore potential mechanisms for monitoring and enhancing the quality and reliability of health communication using social media. Further robust and comprehensive evaluation and review, using a range of methodologies, are required to establish whether social media improves health communication practice both in the short and long terms.

Engagement in social media environments for individuals with who use augmentative and alternative communication.

PubMed

Caron, Jessica

2016-10-14

Communicative interactions, despite the mode (e.g., face-to-face, online) rely on the communication skills of each individual participating. Some individuals have significant speech and language impairments and require the use of augmentative and alternative communication (AAC) (i.e., signs, speech generating devices) to maximize their communication participation across a variety of on and offline contexts. Use of social media has brought about changes to communication environments, contributing new contexts for engagement. To provide a framework for considering application of engagement theory for interventions around social media use by individuals who use AAC. The author has applied examples from qualitative social media and AAC research to a framework of engagement. No formal data collection was used. Social media use has become a conventional form of communication. Yet recognition of the value of social media (and other electronic modalities) for individuals who use AAC has not been fully translated into practice. The examples used illustrated how the proposed framework can assist in clinical practice and future research directions. Engagement, including the proposed framework for considerations of social media engagement activities, can provide a systematic way to approach social media use for individuals who use AAC.

Auditory processing theories of language disorders: past, present, and future.

Miller, Carol A

2011-07-01

The purpose of this article is to provide information that will assist readers in understanding and interpreting research literature on the role of auditory processing in communication disorders. A narrative review was used to summarize and synthesize the literature on auditory processing deficits in children with auditory processing disorder (APD), specific language impairment (SLI), and dyslexia. The history of auditory processing theories of these 3 disorders is described, points of convergence and controversy within and among the different branches of research literature are considered, and the influence of research on practice is discussed. The theoretical and clinical contributions of neurophysiological methods are also reviewed, and suggested approaches for critical reading of the research literature are provided. Research on the role of auditory processing in communication disorders springs from a variety of theoretical perspectives and assumptions, and this variety, combined with controversies over the interpretation of research results, makes it difficult to draw clinical implications from the literature. Neurophysiological research methods are a promising route to better understanding of auditory processing. Progress in theory development and its clinical application is most likely to be made when researchers from different disciplines and theoretical perspectives communicate clearly and combine the strengths of their approaches.

2014-09-01

This study examines changes over a 10-year period in consumer reports of communication with health care providers about direct-to-consumer advertised (DTCA) medications. Two rounds of survey data were collected in 2003 and 2012 using repeated cross-sectional procedures to examine consumer willingness to discuss DTCA medications, content and tone of those conversations, and attitudes about the advertisements. In total, 472 surveys were analyzed. Generally, we found physician-patient conversations, attitudes, and behaviors regarding DTCA have changed. Consumers in 2012 reported talking significantly less about the names of the advertised drug, comparing the advertised drug with their current medication, and sharing general information than consumers in 2003. Attitudes toward the advertisements were significantly more negative in 2012 compared to 2003. Of those who specifically asked for a prescription, the proportion of patients who received the prescription was significantly lower in 2012, despite research suggesting increased rates of prescriptions. These results are interpreted in light of previous research about the lack of research examining the actual communication between physicians and patients on this topic. Limitations of the study are provided along with directions for future research about DTCA and physician-patient communication.

Online communication among adolescents: an integrated model of its attraction, opportunities, and risks.

Valkenburg, Patti M; Peter, Jochen

Adolescents far outnumber adults in their use of e-communication technologies, such as instant messaging and social network sites. In this article, we present an integrative model that helps us to understand both the appeal of these technologies and their risks and opportunities for the psychosocial development of adolescents. We first outline how the three features (anonymity, asynchronicity, and accessibility) of online communication stimulate controllability of online self-presentation and self-disclosure among adolescents. We then review research on the risks and opportunities of online self-presentation and self-disclosure for the three components of adolescents' psychosocial development, including identity (self-unity, self-esteem), intimacy (relationship formation, friendship quality, cyberbullying), and sexuality (sexual self-exploration, unwanted sexual solicitation). Existing research suggests several opportunities of online communication, such as enhanced self-esteem, relationship formation, friendship quality, and sexual self-exploration. It also yields evidence of several risks, including cyberbullying and unwanted sexual solicitation. We discuss the shortcomings of existing research, the possibilities for future research, and the implications for educators and health care professionals.

The collection of environmental samples presents a responsibility to return information to the affected participants. Explaining complex and often ambiguous scientific information to a lay audience is a challenge. As shown by environmental justice research, this audience frequently has limited formal education, increasing the challenge for researchers to explain the data collected, the risk indicated by the findings, and action the affected community should take. In this study we describe the development and implementation of a risk communication strategy for environmental pesticide samples collected in the homes of Latino/a migrant and seasonal farmworkers in a community-based participatory research project. The communication strategy was developed with community input and was based on face-to-face meetings with members of participating households. Using visual displays of data effectively conveyed information about individual household contamination and placed it in the context of community findings. The lack of national reference data and definitive standards for action necessitated a simplified risk message. We review the strengths and weaknesses of such an approach and suggest areas for future research in risk communication to communities affected by environmental health risks. PMID:15064174

Relationship of candidate communication and organization skills to oral certification examination scores.

PubMed

Houston, James E; Smith, Everett V

2008-12-01

This study investigated the relationship between candidate's proficiency in communication/organization and ability measures derived from judges' oral examination ratings on a medical specialty certification examination. Judges who rated candidates on the oral examination also provided a separate rating for candidates' communication/organization skills. ANOVA was used to examine differences among levels of communication/organizational skills with respect to candidates' ability measures on the oral examination. There was a statistically significant increase in oral examination measures for candidates with higher levels of communication/organization skills. This supports the hypothesis that candidates who were more proficient in organizing and presenting their responses were more likely to have better performance on the oral examination. Given communication and oral examination ratings were provided by the same judges, future research should investigate whether these preliminary findings generalize to situations in which communication ratings are obtained from independent ratings during and outside the oral examination.

Communication about melanoma and risk reduction after melanoma diagnosis.

PubMed

Rodríguez, Vivian M; Berwick, Marianne; Hay, Jennifer L

2017-12-01

Melanoma patients are advised to perform regular risk-reduction practices, including sun protection as well as skin self-examinations (SSEs) and physician-led examinations. Melanoma-specific communication regarding family risk and screening may promote such behaviors. To this end, associations between patients' melanoma-specific communication and risk reduction were examined. Melanoma patients (N = 169) drawn from a population-based cancer registry reported their current risk-reduction practices, perceived risk of future melanoma, and communication with physicians and relatives about melanoma risk and screening. Patients were, on average, 56 years old and 6.7 years' post diagnosis; 51% were male, 93% reported "fair/very fair" skin color, 75% completed at least some college, and 22% reported a family history of melanoma. Patients reported varying levels of regular (always/nearly always) sun protection: sunscreen use (79%), shade seeking (60%), hat use (54%), and long-sleeve shirt use (30%). Only 28% performed thorough SSE regularly, whereas 92% reported undergoing physician-led skin examinations within the past year. Participants who were female, younger, and had a higher perceived risk of future melanoma were more likely to report past communication. In adjusted analyses, communication remained uniquely associated with increased sunscreen use and SSE. Encouraging melanoma patients to have a more active role in discussions concerning melanoma risk and screening with relatives and physicians alike may be a useful strategy to promote 2 key risk-reduction practices post melanoma diagnosis and treatment. Future research is needed to identify additional strategies to improve comprehensive risk reduction in long-term melanoma patients. Copyright © 2016 John Wiley & Sons, Ltd.

2013-01-01

Teams at NASA have conducted studies of time-delayed communications as it effects human exploration. In October 2012, the Advanced Exploration Systems (AES) Analog Missions project conducted a Technical Interchange Meeting (TIM) with the primary stakeholders to share information and experiences of studying time delay, to build a coherent picture of how studies are covering the problem domain, and to determine possible forward plans (including how to best communicate study results and lessons learned, how to inform future studies and mission plans, and how to drive potential development efforts). This initial meeting s participants included personnel from multiple NASA centers (HQ, JSC, KSC, ARC, and JPL), academia, and ESA. It included all of the known studies, analog missions, and tests of time delayed communications dating back to the Apollo missions including NASA Extreme Environment Mission Operations (NEEMO), Desert Research and Technology Studies (DRATS/RATS), International Space Station Test-bed for Analog Research (ISTAR), Pavilion Lake Research Project (PLRP), Mars 520, JPL Mars Orbiters/Rovers, Advanced Mission Operations (AMO), Devon Island analog missions, and Apollo experiences. Additionally, the meeting attempted to capture all of the various functional perspectives via presentations by disciplines including mission operations (flight director and mission planning), communications, crew, Capcom, Extra-Vehicular Activity (EVA), Behavioral Health and Performance (BHP), Medical/Surgeon, Science, Education and Public Outreach (EPO), and data management. The paper summarizes the descriptions and results from each of the activities discussed at the TIM and includes several recommendations captured in the meeting for dealing with time delay in human exploration along with recommendations for future development and studies to address this issue.

L-Band Digital Aeronautical Communications System Engineering - Initial Safety and Security Risk Assessment and Mitigation

Zelkin, Natalie; Henriksen, Stephen

2011-01-01

This document is being provided as part of ITT's NASA Glenn Research Center Aerospace Communication Systems Technical Support (ACSTS) contract NNC05CA85C, Task 7: "New ATM Requirements--Future Communications, C-Band and L-Band Communications Standard Development." ITT has completed a safety hazard analysis providing a preliminary safety assessment for the proposed L-band (960 to 1164 MHz) terrestrial en route communications system. The assessment was performed following the guidelines outlined in the Federal Aviation Administration Safety Risk Management Guidance for System Acquisitions document. The safety analysis did not identify any hazards with an unacceptable risk, though a number of hazards with a medium risk were documented. This effort represents a preliminary safety hazard analysis and notes the triggers for risk reassessment. A detailed safety hazards analysis is recommended as a follow-on activity to assess particular components of the L-band communication system after the technology is chosen and system rollout timing is determined. The security risk analysis resulted in identifying main security threats to the proposed system as well as noting additional threats recommended for a future security analysis conducted at a later stage in the system development process. The document discusses various security controls, including those suggested in the COCR Version 2.0.

Here we report the methods and output of a workshop examining possible futures of speech and hearing science out to 2030. Using a design thinking approach, a range of human-centered problems in communication were identified that could provide the motivation for a wide range of research. Nine main research programs were distilled and are summarized: (a) measuring brain and other physiological parameters, (b) auditory and multimodal displays of information, (c) auditory scene analysis, (d) enabling and understanding shared auditory virtual spaces, (e) holistic approaches to health management and hearing impairment, (f) universal access to evolving and individualized technologies, (g) biological intervention for hearing dysfunction, (h) understanding the psychosocial interactions with technology and other humans as mediated by technology, and (i) the impact of changing models of security and privacy. The design thinking approach attempted to link the judged level of importance of different research areas to the “end in mind” through empathy for the real-life problems embodied in the personas created during the workshop.

Communication is key in optimizing medical care when a child is approaching end of life (EOL). Research is yet to establish best practices for how medical teams can guide intrafamily communication (including surviving siblings) when EOL care is underway or anticipated for a pediatric patient. While recommendations regarding how medical teams can facilitate communication between the medical team and the family exist, various barriers may prevent the implementation of these recommendations. This review aims to provide a summary of research-to-date on family and medical provider perceptions of communication during pediatric EOL care. Systematic review. Findings from a review of 65 studies suggest that when a child enters EOL care, many parents try to protect their child and/or themselves by avoiding discussions about death. Despite current recommendations, medical teams often refrain from discussing EOL care with pediatric patients until death is imminent for a variety of reasons (e.g., family factors and discomfort with EOL conversations). Parents consistently report a need for honest complete information, delivered with sensitivity. Pediatric patients often report a preference to be informed of their prognosis, and siblings express a desire to be involved in EOL discussions. Families may benefit from enhanced communication around EOL planning, both within the family and between the family and medical team. Future research should investigate a potential role for medical teams in supporting intrafamily communication about EOL challenges and should examine how communication between medical teams and families can be facilitated as EOL approaches.

Intertwining Implicit and Explicit Awareness of Wellbeing to Support Peace of Mind and Connectedness

NASA Astrophysics Data System (ADS)

Dadlani, Pavan; Markopoulos, Panos; Aarts, Emile

An awareness system was designed to provide peace of mind and a sense of connectedness to adults who care for an elderly parent living alone. Our empirical research, including a field trial of six months, confirms the potential of awareness systems to support both generations suggesting that future research should examine, firstly, how to convey long-term trends regarding the wellbeing of the elderly and, secondly, how to intertwine the communication of awareness information with expressive forms of communication. We discuss implications of our studies for the design of ambient intelligent systems supporting awareness between elderly and their adult children.

Ocean observatories have already demonstrated their ability to maintain long-term time series, capture episodic events, provide context for improved shipboard sampling, and improve accessibility to a broader range of participants. Communicating Ocean Sciences, an already existing college course from COSEE-California has demonstrated its ability to teach future scientists essential communication skills. The NSF-funded Communicating Ocean Sciences to Informal Audiences (COSIA) project has leveraged these experiences and others to demonstrate a long-term model for promoting effective science communication skills and techniques applicable to diverse audiences. The COSIA effort is one of the pathfinders for ensuring that the new scientific results from the increasing U.S. investments in ocean observatories is effectively communicated to the nation, and will serve as a model for other fields. Our presentation will describe a long-term model for promoting effective science communication skills and techniques applicable to diverse audiences. COSIA established partnerships between informal science education institutions and universities nationwide to facilitate quality outreach by scientists and the delivery of rigorous, cutting edge science by informal educators while teaching future scientists (college students) essential communication skills. The COSIA model includes scientist-educator partnerships that develop and deliver a college course that teaches communication skills through the understanding of learning theory specifically related to informal learning environments and the practice of these skills at aquariums and science centers. The goals of COSIA are to: provide a model for establishing substantive, long-term partnerships between scientists and informal science education institutions to meet their respective outreach needs; provide future scientists with experiences delivering outreach and promoting the broader impact of research; and provide diverse role models and inquiry-based ocean sciences activities for children and families visiting informal institutions. The following COSIA partners have taught the course: Hampton University - Virginia Aquarium; Oregon State University - Hatfield Marine Science Visitor's Center; Rutgers University - Liberty Science Center; University of California, Berkeley - Lawrence Hall of Science; University of Southern California - Aquarium of the Pacific; and Scripps Institution of Oceanography - Birch Aquarium. Communicating Ocean Sciences has also been taught at Stanford, Woods Hole Oceanographic Institute, University of Oregon (GK-12 program), University of Washington, and others. Data from surveys of students demonstrates improvement in their understanding of how people learn and how to effectively communicate. Providing college students with a background in current learning theory, and applying that theory through practical science communication experiences, will empower future generations of scientists to meet the communication challenges they will encounter in their careers.

Towards Laser Cooling Trapped Ions with Telecom Light

2015-05-01

Quantum information has many potential applications in communication, atomic clocks, and the precision measurement of fundamental constants. Trapped ions are excellent candidates for applications in quantum information because of their isolation from external perturbations, and the precise control afforded by laser cooling and manipulation of the quantum state. For many applications in quantum communication, it would be advantageous to interface ions with telecom light. We present progress towards laser cooling and trapping of doubly-ionized lanthanum, which should require only infrared, telecom-compatible light. Additionally, we present progress on optimization of a second-harmonic generation cavity for laser cooling and trapping barium ions, for future sympathetic cooling experiments. This research is supported by the Army Research Office, Research Corporation for Science Advancement, and Denison University.

Quality and impact assessment in new geoscience communication : future perspectives through digital communication and Big Data exploration techniques

2015-04-01

Since 1990s up to now, climate and environmental science communication has gradually become a priority of policy programmes, a consolidated subject of training and education, a developed and greatly expanded field of professional practices. However, in contrast to this very fast evolution there is presumably a deficit in terms of research and reflection on objective tools to assess the quality and impact of communication activities. The quality of communication in the field of science has become more and more challenging due to the fact that the role of traditional mediators (e.g. well reputed newspapers or broadcasters, science museums), that used to be considered quality guarantors, has now become marginal. Today, a new generation of communication professionals tend to be employed by research institutes to respond to a stronger request to develop accountable research projects, to increase transparency and trust and to disseminate and implementation of research findings. This research aims to understand how communication strategies, addressed to the general public, can optimise the impact of research findings in hydrology for resilient cities. The research will greatly benefit from the development of automated analysis of unstructured Big Data that allows the exploration of huge amounts of digital communication data: blogs, social networks postings, public speeches, press releases, publications, articles... Furthermore, these techniques facilitate the crossing of socio-economic and physical-environmental data and possibly lead to the identification of existing correlations. Case studies correspond to those of several research projects under the umbrella of the Chair "Hydrology for resilient cities" aimed to develop and test new solutions in urban hydrology that will contribute to the resilience of our cities to extreme weather. This research was initiated in the framework of the Interreg IVB project RAINGAIN and pursued in the project Blue Green Dream of the EU KIC Climate and in worldwide collaborations (e.g. TOMACS). These projects involve awareness raising and capacity building activities aimed to stimulate cooperation between scientists, professionals (e.g. water managers, urban planners) and beneficiaries (e.g. concerned citizens, policy makers). They give credence to the fact that the key question is not if geoscientists can act communicators, but how to develop synergies with various actors of geoscience communication with the help of an enlargement of their scientific practices, rather than a detrimental reduction of them.

Veinott, Elizabeth S.; Irwin, Cheryl M.

1993-01-01

Past research has shown crew communication patterns to be associated with overall crew performance, recent flight experience together, low-and high-error crew performance and personality variables. However, differences in communication patterns as a function of aircraft type and level of aircraft automation have not been fully addressed. Crew communications from ten MD-88 and twelve DC-9 crews were obtained during a full-mission simulation. In addition to large differences in overall amount of communication during the normal and abnormal phases of flight (DC-9 crews generating less speech than MD-88 crews), differences in specific speech categories were also found. Log-linear analyses also generated speaker-response patterns related to each aircraft type, although in future analyses these patterns will need to account for variations due to crew performance.

2013-12-01

Cancer is both highly feared and highly newsworthy, and there is a robust body of research documenting the content and effects of cancer news coverage on health behaviors and policy. Recent years have witnessed ongoing, transformative shifts in American journalism alongside rapid advances in communication technology and the public information environment. These changes create a pressing need to consider a new set of research questions, sampling strategies, measurement techniques, and theories of media effects to ensure continued relevance and adaptation of communication research to address critical cancer control concerns. This paper begins by briefly reviewing what we know about the role of cancer news in shaping cancer-related beliefs, attitudes, behaviors, and policies. We then outline challenges and opportunities, both theoretical and methodological, posed by the rapidly changing news media environment and the nature of audience engagement. We organize our discussion around three major shifts associated with the emerging news media environment as it relates to health communication: 1) speed and dynamism of news diffusion, 2) increased narrowcasting of media content for specialized audiences, and 3) broadened participation in shaping media content. In so doing, we articulate a set of questions for future theory and research, in an effort to catalyze innovative communication scholarship to improve cancer prevention and control.

Improving the experiences and health of people with multimorbidity: exploratory research with policymakers and information providers on comorbid arthritis.

PubMed

Ryan, Rebecca E; Hill, Sophie J

2014-01-01

Multimorbidity has emerged as a complex health issue with the burden falling predominantly on patients, families and the primary health care sector. Evidence-informed communication and participation, activities informed by evidence and people's views and experiences, has the potential to improve health outcomes for people with multimorbidity. In recognition of their role in shaping future actions, we conducted focus groups with policymakers and information providers. The aim of this article is to report on the range and impacts of communication problems in multimorbidity, and identify points of intervention. To facilitate and focus dialogue, comorbid arthritis was selected as the case example. Two focus groups were held: one with policymakers and the other with health information providers. Participants were asked to discuss communication problems and possibilities relevant to multimorbidity, using examples from comorbid arthritis where relevant. Participants highlighted three main areas on which to focus future efforts to improve the health outcomes and experiences of people with multimorbidity: (1) make explicit the problems of multimorbidity and communication; (2) recognise that both multimorbidity and communication issues are compounding factors; and (3) consider actions at policy, service, community and individual levels. Examining multimorbidity through the lens of communication issues identified the significant burden across different domains of the health system. The focus on communication may facilitate a cross-disease perspective to emerge and assist with policy development.

The advancement of Micro-Electro-Mechanical-Systems (MEMS), microcontroller technologies and the idea of Internet of Things (IoT) motivates the development of wireless modules (e.g. WiFi, Bluetooth, Zigbee, and LoRa) that are small and affordable. This paper aims to provide detailed information on the development of the LoRaFi board. The LoRaFi 1.0 is a multi-protocol communication board developed by Centre of Excellence for Advanced Sensor Technology (CEASTech). The board was developed for but not limited to monitor the indoor air quality. The board comprises two different wireless communication modules namely, Long-range technology (LoRa) and WiFi (using ESP8266). The board can be configured to communicate either using LoRa or WiFi or both. The board has been tested and the wireless communication operates successfully. Apart from LoRa, WiFi enables data to be forwarded to the cloud/server where the data can be stored for further data analysis. This helps provide users with real-time information on their smartphones or other applications. In the future, researchers will conduct tests to investigate the communication link quality. Newer version with reduced board size and additional wireless communication module will be developed in the future as to increase board flexibility and widen the range of applications that can use the board.

The visual communication of risk.

Lipkus, I M; Hollands, J G

1999-01-01

This paper 1) provides reasons why graphics should be effective aids to communicate risk; 2) reviews the use of visuals, especially graphical displays, to communicate risk; 3) discusses issues to consider when designing graphs to communicate risk; and 4) provides suggestions for future research. Key articles and materials were obtained from MEDLINE(R) and PsychInfo(R) databases, from reference article citations, and from discussion with experts in risk communication. Research has been devoted primarily to communicating risk magnitudes. Among the various graphical displays, the risk ladder appears to be a promising tool for communicating absolute and relative risks. Preliminary evidence suggests that people understand risk information presented in histograms and pie charts. Areas that need further attention include 1) applying theoretical models to the visual communication of risk, 2) testing which graphical displays can be applied best to different risk communication tasks (e.g., which graphs best convey absolute or relative risks), 3) communicating risk uncertainty, and 4) testing whether the lay public's perceptions and understanding of risk varies by graphical format and whether the addition of graphical displays improves comprehension substantially beyond numerical or narrative translations of risk and, if so, by how much. There is a need to ascertain the extent to which graphics and other visuals enhance the public's understanding of disease risk to facilitate decision-making and behavioral change processes. Nine suggestions are provided to help achieve these ends.

Telling the Climate Change Story: Framing and Messaging

NASA Astrophysics Data System (ADS)

Hassol, S. J.

2011-12-01

Scientists have important roles to play in communicating climate change, yet most scientists are not well versed in important aspects of communication. Scientists can improve their communication by helping to develop and deliver effectively framed messages. Research suggests that effective messages about climate change should include science-based descriptions of the risks posed by human-induced warming as well as information about solutions for a better future. Thus, telling the climate change story effectively involves clearly stating that human-induced climate change is happening now and having impacts on society, while also showing that it is not too late to make a difference for the future. For example, framing and messaging should include the fact that lower emissions pathways lead to less severe climate change and fewer impacts than higher emissions pathways. It also involves communicating that there is much we can do to alter our emissions pathway, and that doing these things has other benefits, for example, for human health and the economy. Scientists telling the climate change story should make the threats tangible and the opportunities clear.

Communication about emotions during storybook reading: Effects of an instruction programme for children with Down syndrome.

PubMed

Na, Ji Young; Wilkinson, Krista M

2017-08-07

Children with Down syndrome often have more restricted emotion expression and recognition skills than their peers who are developing typically, and potentially fewer opportunities to learn these skills. This study investigated the effect of the Strategies for Talking about Emotions as PartnerS (STEPS) programme on parents' provision of opportunities for emotion communication using visual communication supports. The study used a single-subject multiple-baseline across participants design with three parent-child dyads. Shared book reading was used as the context for parent instruction and data collection. Parents increased their use of the emotion communication strategies immediately following an instructional session, and continued to use them for the remaining phases of the study. In turn, the children participated more actively in the discussion by making comments about emotions when parents provided more opportunities. The STEPS instructional programme is effective for improving parents' provision of opportunities for discussing emotions during storybook reading with children who have Down syndrome. All parents indicated that they would use the strategy during future reading activities. This paper discusses the results of the study and directions for future research.

Using the iPad to facilitate interaction between preschool children who use AAC and their peers.

Therrien, Michelle C S; Light, Janice

2016-09-01

Social interaction is one of the key components of education, yet children with complex communication needs often face social isolation in the classroom, rarely interacting with same-age peers. This study investigated the impact of the provision of an iPad(®) (1) with an AAC app with visual scene displays and a dyadic turn taking training on the number of communicative turns taken by children with complex communication needs in interaction with same-age peers. Two preschool children with complex communication needs and six peers without disabilities participated in this research. A single-subject, multiple probe across partners design with one replication was used to evaluate the effectiveness of the intervention on the frequency of communicative turns expressed by the children with complex communication needs. Parents, teachers, speech-language pathologists, and the children participated in social validation measures. As a result of intervention, Participant 1 showed immediate gains in the frequency of symbolic communicative turns after the first training session across all three partners (average gains of 30-46 symbolic communicative turns per 10-min session across peer partners). Participant 2 showed some initial gains, but they were not maintained over time (average gains of 11-24 turns across partners). Classroom implications and future research directions are discussed.

Security in the Cache and Forward Architecture for the Next Generation Internet

NASA Astrophysics Data System (ADS)

Hadjichristofi, G. C.; Hadjicostis, C. N.; Raychaudhuri, D.

The future Internet architecture will be comprised predominately of wireless devices. It is evident at this stage that the TCP/IP protocol that was developed decades ago will not properly support the required network functionalities since contemporary communication profiles tend to be data-driven rather than host-based. To address this paradigm shift in data propagation, a next generation architecture has been proposed, the Cache and Forward (CNF) architecture. This research investigates security aspects of this new Internet architecture. More specifically, we discuss content privacy, secure routing, key management and trust management. We identify security weaknesses of this architecture that need to be addressed and we derive security requirements that should guide future research directions. Aspects of the research can be adopted as a step-stone as we build the future Internet.

It is expected that scientific applications executing on future large-scale HPC must be optimized not only in terms of performance, but also in terms of power consumption. As power and energy become increasingly constrained resources, researchers and developers must have access to tools that will allow for accurate prediction of both performance and power consumption. Reasoning about performance and power consumption in concert will be critical for achieving maximum utilization of limited resources on future HPC systems. To this end, we present a unified performance and power model for the Nek-Bone mini-application developed as part of the DOE's CESAR Exascalemore » Co-Design Center. Our models consider the impact of computation, point-to-point communication, and collective communication« less

Silicon-Germanium Fast Packet Switch Developed for Communications Satellites

NASA Technical Reports Server (NTRS)

Quintana, Jorge A.

1999-01-01

Emerging multimedia applications and future satellite systems will require high-speed switching networks to accommodate high data-rate traffic among thousands of potential users. This will require advanced switching devices to enable communication between satellites. The NASA Lewis Research Center has been working closely with industry to develop a state-of-the-art fast packet switch (FPS) to fulfill this requirement. Recently, the Satellite Industry Task Force identified the need for high-capacity onboard processing switching components as one of the "grand challenges" for the satellite industry in the 21st century. In response to this challenge, future generations of onboard processing satellites will require low power and low mass components to enable transmission of services in the 100 gigabit (1011 bits) per second (Gbps) range.

Health literacy is an essential social determinant for promoting and maintaining the health of a population. From a health promotion perspective, explore health literacy issues, concerns and future challenges among Nordic practitioners and researchers. Data were collected in a workshop at the 8 th Nordic Health Promotion Conference, and in a literature review, with articles from five databases. The search included title and abstract with the search terms health literacy* and health literacy as a MeSH term and all the Nordic countries. Qualitative and quantitative analysis were used. Twenty-five persons participated in the workshop. The discussions were summarized in six themes: concept of health literacy in national language; risk of victim blaming; measuring health literacy; content in school curricula on health literacy; new technologies for information and communication; communication and collaboration between different actors in support of health. Forty-three articles on health literacy were identified, mainly conducted within three fields: development, test and adaptation of instruments for measuring health literacy; measurement of health literacy among patients, or other defined target groups and on populations; and developing and evaluating methods/tools for the training of personnel groups or different target groups. There is a need for further studies providing a more in-depth understanding of the health literacy concept, knowledge on how to measure health literacy, ethical aspects, application in intersectoral collaboration as well as the adaptation to new technologies for information and communication in education supporting health literacy. As health literacy is an essential social health determinant, a concern and a future challenge must be, to make the health literacy concept familiar and visible in health promotion policies, research and practice such as health education.

Risk perception, risk communication, and stakeholder involvement for biosolids management and research.

An individual's perception of risk develops from his or her values, beliefs, and experiences. Social scientists have identified factors that affect perceptions of risk, such as whether the risk is knowable (uncertainty), voluntary (can the individual control exposure?), and equitable (how fairly is the risk distributed?). There are measurable differences in how technical experts and citizen stakeholders define and assess risk. Citizen knowledge and technical expertise are both relevant to assessing risk; thus, the 2002 National Research Council panel on biosolids recommended stakeholder involvement in biosolids risk assessments. A survey in 2002 identified some of the factors that influence an individual's perception of the risks involved in a neighbor's use of biosolids. Risk communication was developed to address the gap between experts and the public in knowledge of technical topics. Biosolids management and research may benefit from applications of current risk communication theory that emphasizes (i) two-way communications (dialogue); (ii) that the public has useful knowledge and concerns that need to be acknowledged; and (iii) that what may matter most is the credibility of the purveyor of information and the levels of trustworthiness, fairness, and respect that he or she (or the organization) demonstrates, which can require cultural change. Initial experiences in applying the dialogue and cultural change stages of risk communication theory--as well as consensus-building and joint fact-finding--to biosolids research suggest that future research outcomes can be made more useful to decision-makers and more credible to the broader public. Sharing control of the research process with diverse stakeholders can make research more focused, relevant, and widely understood.

Equine-assisted psychotherapy (EAP) is an innovative emerging approach to mental health treatment. This narrative synthesis explores the current state of knowledge and areas for future research in EAP. Specifically reviewed are qualitative and quantitative empirical studies, including both articles published in peer-reviewed journals and research presented in theses and dissertations. We selected 24 studies for final inclusion in this study, dating between 2005 and 2013, and including the first EAP empirical research completed in 2005. Four of these studies are peer-reviewed journal articles, while 20 are master's theses or doctoral dissertations. The reviewed qualitative research provides initial evidence for the value of EAP for enhancing adolescents' communication and relationship skills. The reviewed experimental and quasi-experimental research provides initial evidence for the value of EAP for enhancing children's and adolescents' emotional, social and behavioural functioning. Yet, conclusions about the effectiveness of EAP must still be considered preliminary due to various methodological limitations in the reviewed research. The narrative review describes these methodological limitations and concludes with recommendations for future research. © 2015 John Wiley & Sons Ltd.

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

Comparison of language used and patterns of communication in interprofessional and multidisciplinary teams.

Can the language used and the patterns of communication differentiate a multidisciplinary team from an interprofessional team? This research question arose from an unexpected outcome of a study that investigated clinical reasoning of health professional team members in the elder care wards of two different hospitals. The issue at stake was the apparent disparity in the way in which the two teams communicated. To further explore this, the original transcribed interview data was analysed from a symbolic interactionist perspective in order that the language and communication patterns between the two teams could be identified and compared. Differences appeared to parallel the distinctions between multidisciplinary and interprofessional teams as reported in the literature. Our observations were that an interprofessional team was characterized by its use of inclusive language, continual sharing of information between team members and a collaborative working approach. In the multidisciplinary team, the members worked in parallel, drawing information from one another but did not have a common understanding of issues that could influence intervention. The implications of these communication differences for team members, team leaders and future research are then discussed.

Towards public health decision support: a systematic review of bidirectional communication approaches.

Dixon, Brian E; Gamache, Roland E; Grannis, Shaun J

2013-05-01

To summarize the literature describing computer-based interventions aimed at improving bidirectional communication between clinical and public health. A systematic review of English articles using MEDLINE and Google Scholar. Search terms included public health, epidemiology, electronic health records, decision support, expert systems, and decision-making. Only articles that described the communication of information regarding emerging health threats from public health agencies to clinicians or provider organizations were included. Each article was independently reviewed by two authors. Ten peer-reviewed articles highlight a nascent but promising area of research and practice related to alerting clinicians about emerging threats. Current literature suggests that additional research and development in bidirectional communication infrastructure should focus on defining a coherent architecture, improving interoperability, establishing clear governance, and creating usable systems that will effectively deliver targeted, specific information to clinicians in support of patient and population decision-making. Increasingly available clinical information systems make it possible to deliver timely, relevant knowledge to frontline clinicians in support of population health. Future work should focus on developing a flexible, interoperable infrastructure for bidirectional communications capable of integrating public health knowledge into clinical systems and workflows.

Risk communication and management are essential to the ethical conduct of research, yet addressing risks may be time consuming for investigators and institutional review boards may reject study designs that seem too risky. This can discourage needed research, particularly in higher-risk protocols or those enrolling potentially vulnerable individuals, such as those with some level of suicidality. Improved mechanisms for addressing research risks may facilitate much needed psychiatric research. To provide mental health researchers with practical approaches to (1) identify and define various intrinsic research risks, (2) communicate these risks to others (eg, potential participants, regulatory bodies, and society), (3) manage these risks during the course of a study, and (4) justify the risks. As part of a National Institute of Mental Health-funded scientific meeting series, a public conference and a closed-session expert panel meeting were held on managing and disclosing risks in mental health clinical trials. The expert panel reviewed the literature with a focus on empirical studies and developed recommendations for best practices and further research on managing and disclosing risks in mental health clinical trials. No institutional review board-review was required because there were no human subjects. Challenges, current data, practical strategies, and topics for future research are addressed for each of 4 key areas pertaining to management and disclosure of risks in clinical trials: identifying and defining risks, communicating risks, managing risks during studies, and justifying research risks. Empirical data on risk communication, managing risks, and the benefits of research can support the ethical conduct of mental health research and may help investigators better conceptualize and confront risks and to gain institutional review board-approval.

Creativity in clinical communication: from communication skills to skilled communication.

PubMed

Salmon, Peter; Young, Bridget

2011-03-01

Medical Education 2011: 45: 217-226 Objectives  The view that training in communication skills produces skilled communication is sometimes criticised by those who argue that communication is individual and intuitive. We therefore examine the validity of the concept of communication as a skill and identify alternative principles to underpin future development of this field. Methods  We critically examine research evidence about the nature of clinical communication, and draw from theory and evidence concerning education and evaluation, particularly in creative disciplines. Results  Skilled communication cannot be fully described using the concept of communication skills. Attempts to do so risk constraining and distorting pedagogical development in communication. Current education practice often masks the difficulties with the concept by introducing subjectivity into the definition and assessment of skills. As all clinical situations differ to some extent, clinical communication is inherently creative. Because it is rarely possible to attribute specific effects to specific elements of communication, communication needs to be taught and evaluated holistically. Conclusions  For communication teaching to be pedagogically and clinically valid in supporting the inherent creativity of clinical communication, it will need to draw from education theory and practice that have been developed in explicitly creative disciplines. © Blackwell Publishing Ltd 2011.

2018-06-01

The purpose of this meta-analysis was to summarize single-case intervention studies in which Functional Communication Training (FCT) involving augmentative and alternative communication (AAC) was implemented in school settings. Overall, the findings suggest that FCT involving AAC was effective in reducing challenging behaviour and promoting aided or unaided AAC use among participants with disability. FCT was more effective for the participants who engaged in less severe forms of challenging behaviour prior to intervention. Additionally, FCT was more effective when informed by a descriptive functional behaviour assessment and delivered within inclusive school settings. Implications for practice and directions for future research related to FCT for students who use AAC are addressed.

Communicating science in social settings

This essay examines the societal dynamics surrounding modern science. It first discusses a number of challenges facing any effort to communicate science in social environments: lay publics with varying levels of preparedness for fully understanding new scientific breakthroughs; the deterioration of traditional media infrastructures; and an increasingly complex set of emerging technologies that are surrounded by a host of ethical, legal, and social considerations. Based on this overview, I discuss four areas in which empirical social science helps clarify intuitive but sometimes faulty assumptions about the social-level mechanisms of science communication and outline an agenda for bench and social scientists—driven by current social-scientific research in the field of science communication—to guide more effective communication efforts at the societal level in the future.

Ntshebe, O; Pitso, J M N; Segobye, A K

2006-08-01

The 'ABC' approach promoted at the beginning of the HIV/AIDS epidemic in Botswana has failed to yield significant behaviour change. Formative research was conducted in urban, semi-urban and rural areas to explore how the use of sociocultural messages depicted in posters elicited people's response to HIV/AIDS-related behaviours. The research interrogated values and practices underpinning Tswana philosophy in relation to parent-child communication, voluntary counselling and testing, condom use and faithfulness. A total of 206 individuals aged 15 - 49 years were purposively interviewed. The results showed that this campaign was perceived as an activation of positive Batswana culture to modify harmful norms, values and social practices, drawing upon those cultural aspects favouring more positive behaviour. We conclude that behaviour change communication should promote links to cultural values and principles. This can be achieved by: communication in other languages in order to reach all groups in Botswana; providing opportunities for venturing into other ways of communicating HIV/AIDS messages to Batswana in light of literacy skills; and using communication media that is developed on the basis of cultural approaches and focuses on segmented population groups.

Interprofessional communication in healthcare: An integrative review.

PubMed

Foronda, Cynthia; MacWilliams, Brent; McArthur, Erin

2016-07-01

The link between miscommunication and poor patient outcomes has been well documented. To understand the current state of knowledge regarding interprofessional communication, an integrative review was performed. The review suggested that nurses and physicians are trained differently and they exhibit differences in communication styles. The distinct frustrations that nurses and physicians expressed with each other were discussed. Egos, lack of confidence, lack of organization and structural hierarchies hindered relationships and communications. Research suggested that training programs with the use of standardized tools and simulation are effective in improving interprofessional communication skills. Recommendations include education beyond communication techniques to address the broader related constructs of patient safety, valuing diversity, team science, and cultural humility. Future directions in education are to add courses in patient safety to the curriculum, use handover tools that are interprofessional in nature, practice in simulation hospitals for training, and use virtual simulation to unite the professions.

Co-Operative Advances in Behavioral Health and Performance Research and Operations

VanderArk, Stephen T.; Leveton, Lauren B.

2011-01-01

In organizations that engage in both operations and applied research, with operational needs guiding research questions and research informing improved operations, the ideal goal is a synergy of ideas and information. In reality, this ideal synergy is often lacking. Real-time operational needs driving day-to-day decisions, lack of communication, lag time in getting research advances plugged into operations can cause both areas to suffer from this gap between operations and research. At Johnson Space Center, the Behavior Health and Performance group (BHP) strives to bridge this gap by following a Human Research Program framework: Expectations of future operational needs identify the knowledge gaps; the gaps in turn guide research leading to a product that is transitioned into operations. Thus, the direction those of us in research take is in direct response to current and future needs of operations. Likewise, those of us in operations actively seek knowledge that is supported by evidence-based research. We make an ongoing effort to communicate across the research and operations gap by working closely with each other and making a conscious effort to keep each other informed. The objective of the proposed panel discussion is to demonstrate through the following presentations the results of a successful collaboration between research and operations and to provide ASMA members with more practical knowledge and strategies for building these bridges to serve our field of practice well. The panel will consist of six presenters from BHP operations, internal BHP research, and external research instigated by BHP who together represent the entire BHP Research Transition to Operations Framework

The Satellite Networks and Architecture Branch has developed the In-Space Internet Node Technology testbed (ISINT) for investigating the use of commercial Internet products for NASA missions. The testbed connects two closed subnets over a tabletop Ka-band transponder by using commercial routers and modems. Since many NASA assets are in low Earth orbits (LEO's), the testbed simulates the varying signal strength, changing propagation delay, and varying connection times that are normally experienced when communicating to the Earth via a geosynchronous orbiting (GEO) communications satellite. Research results from using this testbed will be used to determine which Internet technologies are appropriate for NASA's future communication needs.

Analytic and subjective assessments of operator workload imposed by communications tasks in transport aircraft

Eckel, J. S.; Crabtree, M. S.

1984-01-01

Analytical and subjective techniques that are sensitive to the information transmission and processing requirements of individual communications-related tasks are used to assess workload imposed on the aircrew by A-10 communications requirements for civilian transport category aircraft. Communications-related tasks are defined to consist of the verbal exchanges between crews and controllers. Three workload estimating techniques are proposed. The first, an information theoretic analysis, is used to calculate bit values for perceptual, manual, and verbal demands in each communication task. The second, a paired-comparisons technique, obtains subjective estimates of the information processing and memory requirements for specific messages. By combining the results of the first two techniques, a hybrid analytical scale is created. The third, a subjective rank ordering of sequences of communications tasks, provides an overall scaling of communications workload. Recommendations for future research include an examination of communications-induced workload among the air crew and the development of simulation scenarios.

Conceptualizing and measuring pharmacist-patient communication: a review of published studies.

PubMed

Shah, Bupendra; Chewning, Betty

2006-06-01

Pharmacist-patient communication in community pharmacies has been studied for over 25 years with little effort to evaluate this research comprehensively. The main objective of this review is to examine and summarize how researchers have conceptualized, defined, and measured pharmacist-patient communication across studies and identify gaps in the literature. Articles were compiled from a search of (1) Medline, IPA, CINAHL, and PubMed databases using the keywords, "counseling", "patient communication", "patient counseling", "patient education", "patient consult( *)", and/or "pharmacists", (2) bibliographies of selected articles. The search generated 56 studies on community pharmacy, of which 39 studies met the inclusion criteria. Most studies (72%) have used the term patient counseling, although pharmacist-patient communication and patient education were also used. The definition of patient counseling varies across studies. Almost half of the studies (49%) conceptualized pharmacist-patient communication solely as a pharmacist information provision activity. A total of 16 studies (41%) also focused on pharmacists' interpersonal behavior in addition to the information provision activity of the pharmacist. In contrast, patient communication behavior and the exchange process between both parties has been understudied. A total of 16 studies (41%) used a retrospective design. All studies used a cross-sectional design, with varying modes of data collection such as mail surveys, telephone interviews, nonparticipant observation, and shopper studies. Taped encounters are rare. SUMMARY/IMPLICATIONS: This review revealed that most studies have focused on a one way communication of pharmacists to patients. A need for examining the patient-pharmacist dyad is apparent. Future research could explore a greater use of taped encounters to analyze the interactive communication process, affective components of communication such as collaborative problem solving, interpersonal relationship development, and the expertise that patients bring into the encounter.

Parental influences on adolescent decision making and contraceptive use.

2010-01-01

This article reviews the literature in the area of parental and maternal influences on contraceptive decision making, thus determining future directions of research and potential interventions. A review of published literature using PubMed, CINAHL, Infotrak, Science and Technology, and Medline spanning 1980-2007 was used to gather information. Results from 35 research studies and 15 scholarly articles were included. The search terms adolescent decision making, maternal influences on adolescent contraceptive decision making, adolescent contraceptive decision making, paternal influences on adolescent decision making, and contraception were used to gather data. The literature reveals there is an association between parental communication, parenting style, and adolescent sexual activity and contraception use. Maternal communication has been shown to delay sexual intercourse and increase contraceptive use. Maternal communication has rich potential as an intervention to impact positive adolescent sexual decision making and contraception use. Gaps in the research identified were the lack of studies on the influences on parenting style and the father/adolescent influences on sexual initiation and contraceptive decision making.

To investigate the past and current status of teaching communication skills in undergraduate medical education and to review how medical education is progressing. A selective search was conducted of the literature that was published from 1960 to Jun 2008 in the MEDLINE, EMBASE, ERIC, Psychlnfo, and KMbase databases using "communication." All articles in 13 medical journals (including Academic Medicine, Medical Education, Teaching and Learning in Medicine, Medical Teacher, and Korean Journal of Medical Education) were reviewed. Each article was categorized according to 5 subjects (curriculum, methods, assessment, student factors, and research type). A total of 306 studies met the inclusion criteria for this study. Curriculum was the most frequent subject (n=85), followed by assessment (n=71), student factors (n=48), and methods (n=23). According to this research, the current trends of teaching communication skills in medical school are characterized by curriculum development,' 'blended-methods,' 'multisource assessment,' 'student attitudes,' and 'comparative studies' of education. It is time to figure it out optimistic ways to design a formal course. Now, 4 current trends in teaching and learning are emerging in communication skills. Curriculum development is stabilizing a variety of teaching methods are being adopted; a method of multisource assessment is being identified and the need to consider student attitudesis being recognized. In the near future, objective, comprehensive, and sophisticated evaluation is going to be the top priority in teaching communication skills with a variety of research types.

Caregivers of young children with hearing loss make decisions about which communication mode/s and spoken language/s their children and family will use. Influences on decision-making about communication were examined for 177 caregivers of Australian children with hearing loss through a questionnaire. The majority of the 157 children used speech as part or all of their communication system (n = 138, 87.9%), and approximately one-third of the children (n = 52, 33.1%) currently or had previously used sign as part or all of their communication system. Twenty-two (14.0%) children and 35 (19.8%) caregivers used a spoken language other than English. Four themes emerged from the qualitative analysis of caregiver responses about the most important influences on their decision-making. Theme one identified caregivers’ sources of information, including advice from professionals, family, and friends, as well as caregivers’ own research and preferences. Theme two related to practicalities of communication within the family and the community, as well as the need for one language or communication mode to be acquired before another was introduced. Theme three described the influence of children’s individual characteristics on caregivers’ decision-making, including children’s ability to access speech through audition, communication skills, additional disabilities, and children’s own preferences about communication. Finally, in theme four caregivers expressed their hopes for their children’s future lives, specifically fostering a sense of belonging, creating future opportunities and successes, and giving children the opportunity to choose their own method of communication. The findings can assist families and professionals to make informed decisions about children’s communication. PMID:25349528

Don't Explain so Much at Once, and Other Lessons From the Young Reviewers of Frontiers for Young Minds

NASA Astrophysics Data System (ADS)

Baker, A. M.

2015-12-01

Most public communication about cutting-edge science happens through a series of filters - press teams, science journalists, news outlets, or even bloggers. Unfortunately, these filters can sometimes lead to research being presented in a way that demotivates the researchers from wanting to translate their science for a broader audience in the future. Frontiers for Young Minds was developed to bridge this gap by publishing plain-language research articles that are written by scientists about their own research and "peer reviewed" by kids ages 8-15 for their own young peers. Though Frontiers for Young Minds authors know that they are creating a high-quality science resource that will be freely available online, many are surprised by the lessons they stand to learn by having direct access to their target audience for feedback. The young reviewers can be refreshingly blunt, questioning everything from why money was spent on such a project to why researchers would make something that should be exciting "too boring to even finish reading." Frontiers for Young Minds is compiling this feedback to create guides for researchers who want to translate their research for young readers, including: using your structure as part of the communication process, the dangers of explaining too much at once, reading to learn, limitations in vocabulary for different age groups, outreach figures - vs - research figures, defining your communication goals, communicating motivation and context, and sharing your excitement. We are working to share our experiences and create resources that will not only be useful for people participating in Frontiers for Young Minds, but for anyone who wants to become a better science communicator.

2015-12-01

This research evaluates the public education earthquake information prior to the Canterbury Earthquake sequence (2010-present), and examines communication learnings to create recommendations for improvement in implementation for these types of campaigns in future. The research comes from a practitioner perspective of someone who worked on these campaigns in Canterbury prior to the Earthquake Sequence and who also was the Public Information Manager Second in Command during the earthquake response in February 2011. Documents, specifically those addressing seismic risk, that were created prior to the earthquake sequence, were analyzed, using a "best practice matrix" created by the researcher, for how closely these aligned to best practice academic research. Readability tests and word counts are also employed to assist with triangulation of the data as was practitioner involvement. This research also outlines the lessons learned by practitioners and explores their experiences in regards to creating these materials and how they perceive these now, given all that has happened since the inception of the booklets. The findings from the research showed these documents lacked many of the attributes of best practice. The overly long, jargon filled text had little positive outcome expectancy messages. This probably would have failed to persuade anyone that earthquakes were a real threat in Canterbury. Paradoxically, it is likely these booklets may have created fatalism in publics who read the booklets. While the overall intention was positive, for scientists to explain earthquakes, tsunami, landslides and other risks to encourage the public to prepare for these events, the implementation could be greatly improved. This final component of the research highlights points of improvement for implementation for more successful campaigns in future. The importance of preparedness and science information campaigns can be not only in preparing the population but also into development of crisis communication plans. These plans are prepared in advance of a major emergency and symbiotic development of strategies, messages, themes and organizational structures in the preparedness stage can impact successful crisis communication plan implementation during an emergency.

Stylistic features of case reports as a genre of medical discourse.

2017-03-13

The present paper discusses the lexical and grammatical peculiarities of English language medical case reports, taking into account their communicative purposes and intentions. The objective of the research is to clarify the principal mechanisms of producing an effective English language medical case report and thus to provide recommendations and guidelines for medical professionals who will deal with this genre. The analysis of medical case reports will largely focus on the most significant linguistic peculiarities, such as the use of active and passive voice, the choice of particular verb tenses, and pronouns. The selected medical case reports will be considered using methods of lexico-grammatical analysis, quantitative examination, and contextual, structural, narrative, and stylistic analyses. The research revealed a range of important stylistic features of medical case reports which markedly distinguish them from other genres of medical scientific writing: educational and instructive intentions, conciseness and brevity, direct and personal tone, and material presented in a narrative style. The present research has shown that the communicative strategies of the analyzed discourse, mentioned immediately above, are effectively implemented by means of specific lexical units and grammatical structures: the dominance of active voice sentences, past simple tense, personal pronouns, and modal verbs. The research has also detected the occasional use of the present perfect, present simple, and future simple tenses and passive voice which also serve particular communicative purposes of medical case reports. Medical case reports possess a range of unique characteristics which differ from those of research articles and other scientific genres within the framework of written medical discourse. It is to be emphasized that it is highly important for medical professionals to master the major stylistic principles and communicative intentions of medical case report as a genre in order to share their findings with fellow researchers from all over the world. Hence, in the process of training future medical researchers, the analysis of the basic mechanisms of writing a medical case report should be an integral part of the curricula in English for Specific Purposes at universities.

Postural Communication of Emotion: Perception of Distinct Poses of Five Discrete Emotions.

PubMed

Lopez, Lukas D; Reschke, Peter J; Knothe, Jennifer M; Walle, Eric A

2017-01-01

Emotion can be communicated through multiple distinct modalities. However, an often-ignored channel of communication is posture. Recent research indicates that bodily posture plays an important role in the perception of emotion. However, research examining postural communication of emotion is limited by the variety of validated emotion poses and unknown cohesion of categorical and dimensional ratings. The present study addressed these limitations. Specifically, we examined individuals' (1) categorization of emotion postures depicting 5 discrete emotions (joy, sadness, fear, anger, and disgust), (2) categorization of different poses depicting the same discrete emotion, and (3) ratings of valence and arousal for each emotion pose. Findings revealed that participants successfully categorized each posture as the target emotion, including disgust. Moreover, participants accurately identified multiple distinct poses within each emotion category. In addition to the categorical responses, dimensional ratings of valence and arousal revealed interesting overlap and distinctions between and within emotion categories. These findings provide the first evidence of an identifiable posture for disgust and instantiate the principle of equifinality of emotional communication through the inclusion of distinct poses within emotion categories. Additionally, the dimensional ratings corroborated the categorical data and provide further granularity for future researchers to consider in examining how distinct emotion poses are perceived.

Human-robot systems are expected to have a central role in future space exploration missions that extend beyond low-earth orbit [1]. As part of a directed research project funded by NASA s Human Research Program (HRP), researchers at the Johnson Space Center have started to use a variety of techniques, including literature reviews, case studies, knowledge capture, field studies, and experiments to understand critical human-robot interaction (HRI) variables for current and future systems. Activities accomplished to date include observations of the International Space Station s Special Purpose Dexterous Manipulator (SPDM), Robonaut, and Space Exploration Vehicle (SEV), as well as interviews with robotics trainers, robot operators, and developers of gesture interfaces. A survey of methods and metrics used in HRI was completed to identify those most applicable to space robotics. These methods and metrics included techniques and tools associated with task performance, the quantification of human-robot interactions and communication, usability, human workload, and situation awareness. The need for more research in areas such as natural interfaces, compensations for loss of signal and poor video quality, psycho-physiological feedback, and common HRI testbeds were identified. The initial findings from these activities and planned future research are discussed.

2018-01-01

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

Marketing health services: the engineering of satisfaction.

PubMed

MacStravic, R S

1984-12-01

Service marketing is the engineering of satisfaction, and the key to success is to identify and influence potential customers' expectations and then to fulfill those expectations. Patient satisfaction largely determines both a program's revenues and expenditures and the effectiveness of care received by patients. A program's ability to satisfy patients rests upon three basic elements: research, design, and communication. Research should be on two levels. The first is basic market assessment and analysis, and should reveal overall market potential by focusing on consumers' expectations, unmet needs, and level of satisfaction. From this stage of research, the organization should be able to identify current programs that are secure and stable, those which have significant growth potential, those which are threatened by competition, and those which have little future. This research also should indicate the potential for new programs and for new markets for existing programs. The second level of research focuses on a specific program (whether current or proposed) and is the basis for program design. The organization can tailor the program to consumers' expectations in everything from services provided to price of parking and other amenities. Research also provides a basis for communications. Not only can communications influence a potential customer to try a provider, but also care providers can use communications during and after the service experience to reinforce what might have been a casual decision. Ideally, all communication that occurs between patients and providers should serve marketing as well as diagnostic and therapeutic purposes. It can shape patients' expectations, reinforce satisfaction when those expectations have been fulfilled, and convey the provider's caring and concern.

Recently the psychological effects of space flight have gained in attention. In uncovering the psychological challenges that individuals and teams can face, we need research options that integrate psychosocial aspects with behavioral, performance, technical and environmental issues. Future perspectives in Space Psychology and Human Spaceflight are reviewed in this paper. The topics covered include psychosocial and neurobehavioural aspects, neurocognitive testing tools, decision making, autonomy and delayed communications, well being, mental health, situational awareness, and methodology. Authors were members of a European Space Agency (ESA) Research Topical Team on Psychosocial and Behavioral Aspects of Human Spaceflight. They discuss the different topics under a common perspective of a theoretical and practical framework, showing interactions, relationships and possible solutions for the different aspects and variables in play. Recommendations for every topic are offered and summarized for future research in the field. The different proposed research ideas can be accomplished using analogs and simulation experiments, short- and long-duration bed rest, and in-flight microgravity studies. These topics are especially important for future Moon and Mars mission design and training.

Assessing Mand Topography Preference When Developing a Functional Communication Training Intervention.

PubMed

Kunnavatana, S Shanun; Wolfe, Katie; Aguilar, Alexandra N

2018-05-01

Functional communication training (FCT) is a common function-based behavioral intervention used to decrease problem behavior by teaching an alternative communication response. Therapists often arbitrarily select the topography of the alternative response, which may influence long-term effectiveness of the intervention. Assessing individual mand topography preference may increase treatment effectiveness and promote self-determination in the development of interventions. This study sought to reduce arbitrary selection of FCT mand topography by determining preference during response training and acquisition for two adults with autism who had no functional communication skills. Both participants demonstrated a clear preference for one mand topography during choice probes, and the preferred topography was then reinforced during FCT to reduce problem behavior and increase independent communication. The implications of the results for future research on mand selection during FCT are discussed.

The existing National Airspace System (NAS) communications capabilities are largely unsecured, are not designed for efficient use of spectrum and collectively are not capable of servicing the future needs of the NAS with the inclusion of new operators in Unmanned Aviation Systems (UAS) or On Demand Mobility (ODM). SNAC will provide a ubiquitous secure, network-based communications architecture that will provide new service capabilities and allow for the migration of current communications to SNAC over time. The necessary change in communication technologies to digital domains will allow for the adoption of security mechanisms, sharing of link technologies, large increase in spectrum utilization, new forms of resilience and redundancy and the possibly of spectrum reuse. SNAC consists of a long term open architectural approach with increasingly capable designs used to steer research and development and enable operating capabilities that run in parallel with current NAS systems.

The Relationship of Patient-Provider Communication on Quality of Life among African-American and White Cancer Survivors.

Prior research has demonstrated poorer patient-provider communication ratings among African American compared to White patients. The quality of patient-provider communication has been shown to impact treatment outcomes among cancer patients. A secondary data analysis design was used to determine the relationship of six patient-provider communication variables on the physical health quality of life (PHQOL) and mental health quality of life (MHQOL) of African American and White cancer patients (N = 479). We also examined whether the relationship between communication patterns and QOL differed based on race/ethnicity. Mean physical and mental health QOL scores for the sample were 69.8 and 77.6, respectively. After controlling for significant sociodemographic, clinical, and hospital variables, results showed that patients who experienced fewer interpersonal communication barriers who were more satisfied with the information given by providers had higher PHQOL and MHQOL scores. Additionally, patients who felt more comfort in asking questions or had fewer unmet information needs had higher MHQOL. A stratified analysis showed that the relationship of overall satisfaction with information on MHQOL was stronger among African American patients than White patients. Future research should focus on the development of interventions to improve patient-provider communication as a means for enhancing QOL outcomes among cancer survivors.

NASA Glenn Research Center (GRC) is responsible for the Advanced Communications for Air Traffic Management (AC/ATM) Project, a sub-element task of the Advanced Air Transportation Technologies (AATT) Project of the NASA Aviation System Capacity Program (ASC). The AC/ATM Project is developing new communications technologies and tools that will improve throughput in the U.S. Air Traffic Control System. The goal of the AC/ATM Project is to enable a communications infrastructure providing the capacity, efficiency, and flexibility necessary to realize benefits of the future mature Free-Flight environment. The capabilities and scope of communications technologies needed to accomplish this goal depend on characteristics of the future Free-Flight environment. There are many operational concepts being proposed for a future ATM system to enable user flexibility and efficiency. GRC s focus is on developing new technologies and techniques to support the digital communication of information involving airborne and ground-based users. However, the technologies and techniques must be integrated with the systems and services that industry and the Federal Aviation Administration (FAA) are developing. Thus, GRC needs to monitor and provide input to the various industry and FAA organizations and committees that are specifying new systems and services. Adoption of technologies by the FAA is partially dependent on acceptance of the technology by the aviation community. The commercial aviation community in particular would like to adopt technologies that can be used throughout the world. As a result, the adoption of common or at least compatible technologies by European countries is a key factor in getting commitments to those technologies by the US aviation community. GRC desires to keep informed of European activities that relate to aviation communication technologies, particularly those that are being supported by Eurocontrol.

A New Dimension of Health Care: Systematic Review of the Uses, Benefits, and Limitations of Social Media for Health Communication

2013-01-01

Background There is currently a lack of information about the uses, benefits, and limitations of social media for health communication among the general public, patients, and health professionals from primary research. Objective To review the current published literature to identify the uses, benefits, and limitations of social media for health communication among the general public, patients, and health professionals, and identify current gaps in the literature to provide recommendations for future health communication research. Methods This paper is a review using a systematic approach. A systematic search of the literature was conducted using nine electronic databases and manual searches to locate peer-reviewed studies published between January 2002 and February 2012. Results The search identified 98 original research studies that included the uses, benefits, and/or limitations of social media for health communication among the general public, patients, and health professionals. The methodological quality of the studies assessed using the Downs and Black instrument was low; this was mainly due to the fact that the vast majority of the studies in this review included limited methodologies and was mainly exploratory and descriptive in nature. Seven main uses of social media for health communication were identified, including focusing on increasing interactions with others, and facilitating, sharing, and obtaining health messages. The six key overarching benefits were identified as (1) increased interactions with others, (2) more available, shared, and tailored information, (3) increased accessibility and widening access to health information, (4) peer/social/emotional support, (5) public health surveillance, and (6) potential to influence health policy. Twelve limitations were identified, primarily consisting of quality concerns and lack of reliability, confidentiality, and privacy. Conclusions Social media brings a new dimension to health care as it offers a medium to be used by the public, patients, and health professionals to communicate about health issues with the possibility of potentially improving health outcomes. Social media is a powerful tool, which offers collaboration between users and is a social interaction mechanism for a range of individuals. Although there are several benefits to the use of social media for health communication, the information exchanged needs to be monitored for quality and reliability, and the users’ confidentiality and privacy need to be maintained. Eight gaps in the literature and key recommendations for future health communication research were provided. Examples of these recommendations include the need to determine the relative effectiveness of different types of social media for health communication using randomized control trials and to explore potential mechanisms for monitoring and enhancing the quality and reliability of health communication using social media. Further robust and comprehensive evaluation and review, using a range of methodologies, are required to establish whether social media improves health communication practice both in the short and long terms.

Abstract Background: In a world of finite research funding, efforts to prioritize future research topics are increasingly necessary. Objective: The aim of this study was to identify and prioritize the direction of future research in the broad area of low-calorie sweetener (LCS) intake and potentially related health outcomes by using a novel method that incorporates evidence mapping in the Agency for Healthcare Research and Quality's Future Research Needs (FRN) process. Methods: A diverse expert stakeholder panel was convened and engaged to identify research gaps and prioritize future research needs. An independent research team hosted a number of interactive webinars and elicited feedback through surveys and individual interviews with the stakeholder panel, which included policymakers, lay audience members, health providers, a research funder, individuals with food industry experience, and researchers of several different specialties. Results: The stakeholder panel generated and ranked a list of 18 FRN questions across 5 broad research areas. Overall, stakeholder panel members unanimously agreed that the research questions that will have the largest public health impact are those that address outcomes related to body weight, appetite, and dietary intake. Although the LCSs included in this FRN project have all been Generally Recognized as Safe by the FDA or approved as food additives, the recurrent concerns and confusions with regard to the “safety” of LCSs by consumers underscore the importance of communicating the science to the general public. Conclusion: Our project provides evidence that engaging a diverse expert stakeholder panel is an effective method of translating gaps in nutrition research into prioritized areas of future research.

Pro-ana versus Pro-recovery: A Content Analytic Comparison of Social Media Users’ Communication about Eating Disorders on Twitter and Tumblr

2017-01-01

Objectives: To compare how people communicate about eating disorders on two popular social media platforms – Twitter and Tumblr. Materials and Methods: Thematic analysis was conducted to characterize the types of communications posted, and a content analysis was undertaken of between-platform differences. Results: Three types of content (pro-ana, anti-ana, and pro-recovery) were posted on each platform. Overall, across both platforms, extreme pro-ana posts were in the minority compared to anti-ana and pro-recovery. Pro-ana posts (including ‘thinspiration’) were more common on Twitter than Tumblr, whereas anti-ana and pro-recovery posts were more common on Tumblr. Conclusion: The findings have implications for future research and health care relating to the treatment and prevention of eating disorders. Developers of future interventions targeting negative pro-ana content should remain aware of the need to avoid any detrimental impact on positive online support. PMID:28848472

Analysis of Pervasive Mobile Ad Hoc Routing Protocols

NASA Astrophysics Data System (ADS)

Qadri, Nadia N.; Liotta, Antonio

Mobile ad hoc networks (MANETs) are a fundamental element of pervasive networks and therefore, of pervasive systems that truly support pervasive computing, where user can communicate anywhere, anytime and on-the-fly. In fact, future advances in pervasive computing rely on advancements in mobile communication, which includes both infrastructure-based wireless networks and non-infrastructure-based MANETs. MANETs introduce a new communication paradigm, which does not require a fixed infrastructure - they rely on wireless terminals for routing and transport services. Due to highly dynamic topology, absence of established infrastructure for centralized administration, bandwidth constrained wireless links, and limited resources in MANETs, it is challenging to design an efficient and reliable routing protocol. This chapter reviews the key studies carried out so far on the performance of mobile ad hoc routing protocols. We discuss performance issues and metrics required for the evaluation of ad hoc routing protocols. This leads to a survey of existing work, which captures the performance of ad hoc routing algorithms and their behaviour from different perspectives and highlights avenues for future research.

Parent-adolescent sexual communication has received considerable attention as a factor that can positively affect safer sex behavior among youth; however, the evidence linking such communication to youth contraceptive and condom use has not been empirically synthesized. To examine the effect of parent-adolescent sexual communication on safer sex behavior among youth and explore potential moderators of this association. A systematic search of studies published from database inception through June 30, 2014, using the MEDLINE, PsycINFO, and Communication & Mass Media Complete databases and relevant review articles yielded 5098 studies, of which 52 studies with 25,314 adolescents met the study eligibility criteria. Analysis was conducted from July 1, 2014, to July 27, 2015. Studies were included if they sampled adolescents (mean sample age ≤18 years), included an adolescent report of sexual communication with one or both parents, measured safer sex behavior, and were published in English. Correlation coefficients (r) and 95% CIs were computed from studies and meta-analyzed using random-effects models. Safer sex behavior, including use of contraceptives or condoms. Fifty-two articles, including 71 independent effects representing more than 3 decades of research on 25,314 adolescents (weighted mean age, 15.2 years) were synthesized. Across studies, there was a significant weighted mean effect (r = 0.10; 95% CI, 0.08-0.13) linking parent-adolescent sexual communication with safer sex behavior, which was statistically heterogeneous (Q = 203.50, P < .001, I2 = 65.60). Moderation analyses revealed larger effects for communication with girls (r = 0.12) than boys (r = 0.04) and among youth who discussed sex with their mothers (r = 0.14) compared with their fathers (r = 0.03). Effects did not differ for contraceptive vs condom use or among longitudinal vs cross-sectional studies, indicating that parent sexual communication had a similar effect across study designs and outcomes. Several methodological issues were identified in the literature; future studies can improve on these issues by measuring parent-adolescent communication with robust, multi-item measures, clearly specifying the target parent, and applying multimethod longitudinal designs. Sexual communication with parents, particularly mothers, plays a small protective role in safer sex behavior among adolescents; this protective effect is more pronounced for girls than boys. We discuss the implications for practice and make suggestions for future research on parent-adolescent sexual communication.

Importance Parent-adolescent sexual communication has received considerable attention as one factor that can positively impact safer sex among youth; however, the evidence linking communication to youth contraceptive and condom use has not been empirically synthesized. Objective This meta-analysis examined the effect of parent-adolescent sexual communication on youth safer sex behavior and explored potential moderators of this association. Data Sources A systematic search was conducted of studies published through June 2014 using Medline, PsycINFO, and Communication & Mass Media Complete databases and relevant review articles. Study Selection Studies were included if they: 1) sampled adolescents (mean sample age≤18); 2) included an adolescent report of sexual communication with parent(s); 3) measured safer sex behavior; and 4) were published in English. Data Extraction and Synthesis Correlation coefficients (r) and 95% confidence intervals (CIs) were computed from studies and meta-analyzed using random-effects models. Main Outcomes and Measures The primary outcome was safer sex behavior, including use of contraceptives/birth control or condoms. Results Seventy-one independent effects representing over three decades of research on 25,314 adolescents (mean age = 15.1) were synthesized. Across studies, there was a small, significant weighted mean effect (r = .10, [95% CI:0.08–0.13]) linking parent-adolescent sexual communication to safer sex behavior, which was statistically heterogeneous (Q = 203.50, p < .001, I2 = 65.60). Moderation analyses revealed larger effects for communication with girls (r = .12) than boys (r = .04), and among youth who discussed sex with mothers (r = .14) compared to fathers (r = .03). Effects did not differ for contraceptive versus condom use, or among longitudinal versus cross-sectional studies, indicating parent sexual communication had a similar impact across study designs and outcomes. Several methodological issues were identified in the literature; future studies can improve on these by measuring parent-adolescent communication with robust, multi-item measures, clearly specifying the target parent, and applying multi-method longitudinal designs. Conclusions and Relevance Sexual communication with parents, particularly mothers, plays a small protective role in adolescent safer sex behavior, and this protective effect is more pronounced for girls than boys. Implications for practice and suggestions for future research on parent-adolescent communication are discussed. PMID:26524189

Media Effects: Theory and Research.

Valkenburg, Patti M; Peter, Jochen; Walther, Joseph B

2016-01-01

This review analyzes trends and commonalities among prominent theories of media effects. On the basis of exemplary meta-analyses of media effects and bibliometric studies of well-cited theories, we identify and discuss five features of media effects theories as well as their empirical support. Each of these features specifies the conditions under which media may produce effects on certain types of individuals. Our review ends with a discussion of media effects in newer media environments. This includes theories of computer-mediated communication, the development of which appears to share a similar pattern of reformulation from unidirectional, receiver-oriented views, to theories that recognize the transactional nature of communication. We conclude by outlining challenges and promising avenues for future research.

Virtually Shaping the Future of Polar Research

NASA Astrophysics Data System (ADS)

Baeseman, J. L.; Koldunov, N. V.; Jochum, K.

2009-12-01

The Association of Polar Early Career Scientists (APECS) is an international and interdisciplinary organization for undergraduate and graduate students, postdoctoral researchers, early faculty members, educators and others with interests in Polar Regions and the wider cryosphere that started as a result of the International Polar Year (IPY). APECS is leading the way for virtual communication of polar research through several activities: an online Polar Literature Discussion Forum, a Virtual Poster Session, and Communication beyond the conference setting. APECS has created an extensive online discussion forum where researchers share both classic and cutting-edge literature articles and critique techniques that were used by authors, helping to improve methods as well as discover new ways to approach polar research questions. Many researchers present their results as posters at conferences. APECS has taken this process to a new level by creating a format to display previously presented posters online instead of these files simply sitting on a researcher’s hard-drive. Not only are the posters online, a monthly conference call open to hundreds of participants allows researchers to share their work with a new audience - fellow researchers, community members, potential colleagues, policy makers and educators. These calls are recorded and archived online so the next time someone visits the poster, they can hear the researcher describe their work and communicate with the researcher questions they may have, potential ways to collaborate or share different methodologies to improve future endeavors. Peer-reviewed literature articles are the currency of science and APECS has capitalized on this by creating a way for researchers to increase the exposure of their publications beyond the table of contents published by journals. The Polar Literature Discussion Forum is a new way for researchers to share their papers, as well as discuss classic articles. This has become a popular place where IPY related research is being archived in a non-traditional manner. Researchers are sharing not only their papers, but insights on data collection and how other researchers could improve on what they have done during the IPY. The IPY has created many new research projects and stimulated new questions and created cutting-edge techniques to address these problems. APECS is helping to carry on these discussions beyond the typical conference settings directly to a researcher’s office or at home on their couch. These communication tools will help to stimulate discussion carrying forward the research questions addressed and created during the IPY.

The NASA Glenn Research Center recently demonstrated the ability to securely command and control space-based assets by using the Internet and standard Internet Protocols (IP). This is a significant accomplishment because future NASA missions will benefit by using Internet standards-based protocols. The benefits include reduced mission costs and increased mission efficiency. The Internet-Based Space Command and Control System Architecture demonstrated at the NASA Inspection 2000 event proved that this communications architecture is viable for future NASA missions.

The Emergence of Environmental Health Literacy—From Its Roots to Its Future Potential

PubMed Central

Finn, Symma; O’Fallon, Liam

2015-01-01

Background: Environmental health literacy (EHL) is coalescing into a new subdiscipline that combines key principles and procedural elements from the fields of risk communication, health literacy, environmental health sciences (EHS), communications research, and safety culture. These disciplines have contributed unique expertise and perspectives to the development of EHL. Since 1992, the National Institute of Environmental Health Sciences (NIEHS) has contributed to the evolution of EHL and now seeks to stimulate its scientific advancement and rigor. Objectives: The principal objective of this article is to stimulate a conversation on, and advance research in, EHL. Discussion: In this article, we propose a definition of and conceptual framework for EHL, describe EHL in its social and historical context, identify the complementary fields and domains where EHL is being defined and implemented, and outline a research agenda. Extensive reviews of web and literature searches indicate that the concept of EHL is evolving rapidly, as are the definitions of its scope and inquiry. Although several authors have outlined different frameworks, we believe that a more nuanced model based on Bloom’s taxonomy is better suited to EHL and to future research in this area. Conclusions: We posit that EHL can potentially benefit the conduct and outcomes of community-engaged and health disparities EHS research and can ensure that the translation of research findings will lead to greater understanding of specific risks, reduction of exposures, and improvement of health outcomes for individuals and communities. We provide four recommendations to advance work in EHL. Citation: Finn S, O’Fallon L. 2017. The emergence of environmental health literacy—from its roots to its future potential.

A communication strategy was developed by The Consortium to Perform Human Biomonitoring on a European Scale (COPHES), as part of its objectives to develop a framework and protocols to enable the collection of comparable human biomonitoring data throughout Europe. The framework and protocols were tested in the pilot study DEMOCOPHES (Demonstration of a study to Coordinate and Perform Human biomonitoring on a European Scale). The aims of the communication strategy were to raise awareness of human biomonitoring, encourage participation in the study and to communicate the study results and their public health significance. It identified the audiences and key messages, documented the procedure for dissemination of results and was updated as the project progressed. A communication plan listed the tools and materials such as press releases, flyers, recruitment letters and information leaflets required for each audience with a time frame for releasing them. Public insight research was used to evaluate the recruitment material, and the feedback was used to improve the documents. Dissemination of results was coordinated in a step by step approach by the participating countries within DEMOCOPHES, taking into account specific national messages according to the needs of each country. Participants received individual results, unless they refused to be informed, along with guidance on what the results meant. The aggregate results and policy recommendations were then communicated to the general public and stakeholders, followed by dissemination at European level. Several lessons were learnt that may assist other future human biomonitoring studies. Recruitment took longer than anticipated and so social scientists, to help with community engagement, should be part of the research team from the start. As a European study, involving multiple countries, additional considerations were needed for the numerous organisations, different languages, cultures, policies and priorities. Therefore, communication documents should be seen as templates with essential information clearly indicated and the option for each country to tailor the material to reflect these differences. Future studies should consider setting up multidisciplinary networks of medical professionals and communication experts, and holding training workshops to discuss the interpretation of results and risk communication. Publicity and wide dissemination of the results helped to raise awareness of human biomonitoring to the general public, policy makers and other key stakeholders. Effective and timely communication, at all stages of a study, is essential if the potential of human biomonitoring research to improve public health is to be realised. Copyright © 2015 The Authors.

The first phase of Elsevier's Article of the Future article format was released on SciVerse ScienceDirect in January 2012. While this new format for online scholarly articles brings a significantly improved online presentation, it also enables further enhancements in terms of domain-specific content and contextualization of research results. Of particular interest to the Earth Sciences research community are the seamless integration of an interactive map viewer that displays author-submitted KML files inside the article, and real-time links to leading research data portals like Pangaea and Earthchem. These enhancements allow for a richer form of communication between authors and readers, and present researchers with valuable additional information in the context of the article. In this presentaion I will review these ongoing efforts to enhance online articles in the digital era.

The Future of Climate Change Education and Communication: Preparing Our Posterity for Risks and Opportunity? (Invited)

NASA Astrophysics Data System (ADS)

Ledley, T. S.; Niepold, F.

2013-12-01

Climate change will have impacts on all aspects of life. As such it is a topic that is interdisciplinary and transdisciplinary and thus requires input from a professionally diverse group of experts to be addressed effectively. This represents the next step in an evolution of how geoscientists see their work and their responsibility communicate and collaborate with other professionals to enable their findings and understanding of the Earth system to benefit society. In the late 1970's geoscience research extended beyond the traditional disciplinary perspectives to investigate the interactions of the components of the Earth system and the impacts of those interactions. Geoscience research became interdisciplinary. In the last 10 years as the reality of climate change has become more apparent,it is clear that the conversation needs to extend well beyond the geosciences to include for example agriculture, economics, psychology, architecture, urban planning, engineering and the social sciences. Climate change education and communication needs to become both interdisciplinary and transdisciplinary. This presentation will discuss the obstacles that need to be overcome to achieve interdisciplinary and transdiciplinary ways of addressing the problems and opportunities resulting from climate change, the efforts that are underway to help develop a common language and shared understanding to enable transdisciplinary solutions to societal issues in the future.

Direct observation of weight-related communication in primary care: a systematic review.

McHale, Calum T; Laidlaw, Anita H; Cecil, Joanne E

2016-08-01

Primary care is ideally placed to play an effective role in patient weight management; however, patient weight is seldom discussed in this context. A synthesis of studies that directly observe weight discussion in primary care is required to more comprehensively understand and improve primary care weight-related communication. To systematically identify and examine primary care observational research that investigates weight-related communication and its relationship to patient weight outcomes. A systematic review of literature published up to August 2015, using seven electronic databases (including MEDLINE, Scopus and PsycINFO), was conducted using search terms such as overweight, obese and/or doctor-patient communication. Twenty papers were included in the final review. Communication analysis focused predominantly on 'practitioner' use of specific patient-centred communication. Practitioner use of motivational interviewing was associated with improved patient weight-related outcomes, including patient weight loss and increased patient readiness to lose weight; however, few studies measured patient weight-related outcomes. Studies directly observing weight-related communication in primary care are scarce and limited by a lack of focus on patient communication and patient weight-related outcomes. Future research should measure practitioner and patient communications during weight discussion and their impact on patient weight-related outcomes. This knowledge may inform the development of a communication intervention to assist practitioners to more effectively discuss weight with their overweight and/or obese patients. © The Author 2016.

Coherent Optical Communications: Historical Perspectives and Future Directions

NASA Astrophysics Data System (ADS)

Kikuchi, Kazuro

Coherent optical fiber communications were studied extensively in the 1980s mainly because high sensitivity of coherent receivers could elongate the unrepeated transmission distance; however, their research and development have been interrupted for nearly 20 years behind the rapid progress in high-capacity wavelength-division multiplexed (WDM) systems using erbium-doped fiber amplifiers (EDFAs). In 2005, the demonstration of digital carrier phase estimation in coherent receivers has stimulated a widespread interest in coherent optical communications again. This is due to the fact that the digital coherent receiver enables us to employ a variety of spectrally efficient modulation formats such as M-ary phase-shift keying (PSK) and quadrature amplitude modulation (QAM) without relying upon a rather complicated optical phase-locked loop. In addition, since the phase information is preserved after detection, we can realize electrical post-processing functions such as compensation for chromatic dispersion and polarization-mode dispersion in the digital domain. These advantages of the born-again coherent receiver have enormous potential for innovating existing optical communication systems. In this chapter, after reviewing the 20-year history of coherent optical communication systems, we describe the principle of operation of coherent detection, the concept of the digital coherent receiver, and its performance evaluation. Finally, challenges for the future are summarized.

Interorganellar cooperation maintained via exquisitely controlled retrograde-signaling pathways is an evolutionary necessity for maintenance of cellular homeostasis. This signaling feature has therefore attracted much research attention aimed at improving understanding of the nature of these communication signals, how the signals are sensed, and ultimately the mechanism by which they integrate targeted processes that collectively culminate in organellar cooperativity. The answers to these questions will provide insight into how retrograde-signal-mediated regulatory mechanisms are recruited and which biological processes are targeted, and will advance our understanding of how organisms balance metabolic investments in growth against adaptation to environmental stress. This review summarizes the present understanding of the nature and the functional complexity of retrograde signals as integrators of interorganellar communication and orchestrators of plant development, and offers a perspective on the future of this critical and dynamic area of research.

Storytelling/narrative theory to address health communication with minority populations.

PubMed

Lee, Haeok; Fawcett, Jacqueline; DeMarco, Rosanna

2016-05-01

To explain the development and application of storytelling/narrative theory in health disparities intervention research as a way to promote health communication and behavior change among racial, ethnic, and minority populations. The proposed storytelling theory helps explain that storytelling affects changes in attitude and health behavior of the viewer through realism, identification, and transportation. The proposed storytelling/narrative theory can be a guide to develop culturally grounded narrative interventions that have the ability to connect with hard-to-reach populations. Narrative communication is context-dependent because it derives meaning from the surrounding situation and provides situation-based stories that are a pathway to processing story content. Although storytelling is grounded in nursing practice and education, it is underutilized in nursing interventional research. Future efforts are needed to extend theory-based narrative intervention studies designed to change attitude and behaviors that will reduce health disparities among minorities.

2010-01-01

At the Kennedy Space Center, I engaged in the research and development of electrical ground support equipment for NASA's Constellation Program. Timing characteristics playa crucial role in ground support communications. Latency and jitter are two problems that must be understood so that communications are timely and consistent within the Kennedy Ground Control System (KGCS). I conducted latency and jitter tests using Alien-Bradley programmable logic controllers (PLCs) so that these two intrinsic network properties can be reduced. Time stamping and clock synchronization also play significant roles in launch processing and operations. Using RSLogix 5000 project files and Wireshark network protocol analyzing software, I verified master/slave PLC Ethernet module clock synchronization, master/slave IEEE 1588 communications, and time stamping capabilities. All of the timing and synchronization test results are useful in assessing the current KGCS operational level and determining improvements for the future.

The human capacity to acquire sophisticated language is unmatched in the animal kingdom. Despite the discontinuity in communicative abilities between humans and other primates, language is built on ancient genetic foundations, which are being illuminated by comparative genomics. The genetic architecture of the language faculty is also being uncovered by research into neurodevelopmental disorders that disrupt the normally effortless process of language acquisition. In this article, we discuss the strategies that researchers are using to reveal genetic factors contributing to communicative abilities, and review progress in identifying the relevant genes and genetic variants. The first gene directly implicated in a speech and language disorder was FOXP2. Using this gene as a case study, we illustrate how evidence from genetics, molecular cell biology, animal models and human neuroimaging has converged to build a picture of the role of FOXP2 in neurodevelopment, providing a framework for future endeavors to bridge the gaps between genes, brains and behavior.

Caring for the family is included as one of the eight domains of quality palliative care, calling attention to the importance of the family system and family communications about cancer during care and treatment of the disease. Previously, a model of family caregiver communication defined four caregiver communication types-Manager, Carrier, Partner, Lone-each with a unique communication pattern. The purpose of the present study was to extend the model of family caregiver communication in cancer care to further understand the impact of family communication burden on caregiving outcomes. This mixed-method study employed fieldnotes from a family caregiver intervention focused on quality of life and self-reported caregiver communication items to identify a specific family caregiver type. Caregiver types were then analyzed using outcome measures on psychological distress, skills preparedness, family inventory of needs, and quality-of-life domains. Corroboration between fieldnotes and self-reported communication for caregivers (n = 21, 16 women, mean age of 53 years) revealed a definitive classification of the four caregiver types (Manager = 6, Carrier = 5, Partner = 6, Lone = 4). Mean scores on self-reported communication items documented different communication patterns congruent with the theoretical framework of the model. Variation in caregiver outcomes measures confirmed the model of family caregiver communication types. Partner and Lone caregivers reported the lowest psychological distress, with Carrier caregivers feeling least prepared and Manager caregivers reporting the lowest physical quality of life. This study illustrates the impact of family communication on caregiving and increases our knowledge and understanding about the role of communication in caregiver burden. The research provides the first evidence-based validation for a family caregiver communication typology and its relationship to caregiver outcomes. Future research is needed to develop and test interventions that target specific caregiver types.

Cluster-randomized controlled trials were carried out to examine effects on sexual practices of school-based interventions among adolescents in three sites in sub-Saharan Africa. In this publication, effects on communication about sexuality with significant adults (including parents) and such communication as a mediator of other outcomes were examined. Belonging to the intervention group was significantly associated with fewer reported sexual debuts in Dar es Salaam only (OR 0.648). Effects on communication with adults about sexuality issues were stronger for Dar es Salaam than for the other sites. In Dar, increase in communication with adults proved to partially mediate associations between intervention and a number of social cognition outcomes. The hypothesized mediational effect of communication on sexual debut was not confirmed. Promoting intergenerational communication on sexuality issues is associated with several positive outcomes and therefore important. Future research should search for mediating factors influencing behavior beyond those examined in the present study.

Condom negotiation: findings and future directions.

2015-01-01

The aim of this review was to summarize factors associated with condom negotiation among heterosexual men. Literature searches were conducted using multiple databases spanning several disciplines. Studies examining psychological, demographic, relational, communication, and environmental factors related to condom negotiation are described, and a three-dimensional framework of condom negotiation is proposed. This framework of condom negotiation may aid researchers in operationalizing this construct, organizing this literature, and facilitating measurement development. We used this three-dimensional framework to articulate the influence of gender, ethnicity, relationship type, partner characteristics, trauma history, post-traumatic stress, and alcohol use on condom negotiation. Areas for future research are outlined. More research is needed to understand how these factors interact to influence condom negotiation, as well as the interaction between gender and the identified factors.

Educational trajectories of graduate students in physics education research

Physics education research (PER) is a rapidly growing area of PhD specialization. In this article we examine the trajectories that led respondents into a PER graduate program as well as their expected future trajectories. Data were collected in the form of an online survey sent to graduate students in PER. Our findings show a lack of visibility of PER as a field of study, a dominance of work at the undergraduate level, and a mismatch of future desires and expectations. We suggest that greater exposure is needed so PER is known as a field of inquiry for graduates, that more emphasis should be placed on research beyond the undergraduate level, and that there needs to be stronger communication to graduate students about potential careers.

A synergistic glance at the prospects of distributed propulsion technology and the electric aircraft concept for future unmanned air vehicles and commercial/military aviation

2013-02-01

Distributed propulsion is one of the revolutionary candidates for future aircraft propulsion. In this journal article, the potential role of distributed propulsion technology in future aviation is investigated. Following a historical journey that revisits distributed propulsion technology in unmanned air vehicles and military aircraft, features of this specific technology are highlighted in synergy with an electric aircraft concept and a first-of-a-kind comparison to commercial aircraft employing distributed propulsion arrangements. In light of propulsion-airframe integration and complementary technologies such as boundary layer ingestion, thrust vectoring and circulation control, transpired opportunities and challenges are addressed in addition to a number of identified research directions proposed for future aircraft. The motivation behind enhanced means of communication between engineers, researchers and scientists has stimulated a novel proposed definition for the distributed propulsion technology in aviation and is presented herein.

Foresight Scanning: Future Directions of Clinical and Pharmaceutical Research. Brian C. Foster, Therapeutic Products Directorate, Health Canada, Ottawa, Ontario, Canada ABSTRACT The Canadian Society for Pharmaceutical Sciences Satellite Symposium on Foresight Scanning, May 26 and 27, 2008, Nordegg, Alberta, Canada, focussed on the future directions of clinical and pharmaceutical research. The symposium brought together a group of clinicians, regulatory scientists, researchers and students to examine where clinical, pharmaceutical, and regulatory science might be in 10 to 15 years. Industry, regulatory, analytical, and clinical perspectives were presented and discussed, as well as the impact of exogenous (indirect) and endogenous (direct) change drivers. Unconditional funding was provided by Bayer HealthCare; they had no input on the direction of the meeting or selection of speakers. It was envisioned that the more important endogenous drivers may not be new information or changes in technology, policy, regulation, or health care delivery, but amplification of long-term underlying trends by emergence of new technologies, convergence of existing technologies or new communication and collaboration vehicles such as Web 2.0.

Modifiable cancer risk factors include lifestyle behaviors related to vaccination, physical activity, weight control and maintenance, alcohol consumption, and tobacco use. These health habits are often formed in young adulthood, a life stage which currently intersects with the growing population of digital natives whose childhood occurred in the internet era. Social media is a critical communication medium to reach this population of digital natives. Using a life course perspective, the purpose of this viewpoint paper is to describe the current landscape of nascent research using social media to target cancer prevention efforts in young adults and propose future directions to strengthen the scientific knowledge supporting social media strategies to promote cancer prevention behaviors. Leveraging social media as a health promotion tool is a promising strategy to impact modifiable behavioral risk factors for cancer and warrants further research on developing effective communication strategies in young adults to prevent cancer in the future generations. ©Urmimala Sarkar, Gem M Le, Courtney R Lyles, Danielle Ramo, Eleni Linos, Kirsten Bibbins-Domingo.

Team working in intensive care: current evidence and future endeavors.

PubMed

Richardson, Joanne; West, Michael A; Cuthbertson, Brian H

2010-12-01

It has recently been argued that the future of intensive care medicine will rely on high quality management and teamwork. Therefore, this review takes an organizational psychology perspective to examine the most recent research on the relationship between teamwork, care processes, and patient outcomes in intensive care. Interdisciplinary communication within a team is crucial for the development of negotiated shared treatment goals and short-team patient outcomes. Interventions for maximizing team communication have received substantial interest in recent literature. Intensive care coordination is not a linear process, and intensive care teams often fail to discuss how to implement goals, trigger and align activities, or reflect on their performance. Despite a move toward interdisciplinary team working, clinical decision-making is still problematic and continues to be perceived as a top-down and authoritative process. The topic of team leadership in intensive care is underexplored and requires further research. Based on findings from the most recent research evidence in medicine and management, four principles are identified for improving the effectiveness of team working in intensive care: engender professional efficacy, create stable teams and leaders, develop trust and participative safety, and enable frequent team reflexivity.

How interpersonal communication mediates the relationship of multichannel communication connections to health-enhancing and health-threatening behaviors.

PubMed

Seo, Mihye; Matsaganis, Matthew D

2013-08-01

This article examines how everyday media use and interpersonal communication for health information could influence health behaviors beyond intervention or campaign contexts. The authors argue that interpersonal communication works as an independent information channel and mediates the relation between media channels and health behaviors. In addition, the authors investigate whether interpersonal communication differently influences the relation between media connections and health behaviors for more and less educated individuals. Using data from the 2008 Annenberg National Health Communication Survey, the authors show that multiple communication channels for health information encourage health-enhancing behaviors but do not have significant relations with health-threatening behaviors. Interpersonal communication is directly linked to health-enhancing behaviors, but it also mediates the influence of individuals' multichannel media environment on health-enhancing behaviors. The mediating role of interpersonal health communication was only significant for less educated people. In addition, among media channels, television was a more important instigator of health-related conversations with family and friends for the less educated group. The theoretical and practical implications of these findings, as well as suggestions for future research directions, are discussed.

In this article, we examine parent-adolescent communication about sex among rural Indian youth and their parents. We conducted in-depth interviews (N = 40) with mothers, fathers, and adolescent boys and girls aged 14 to 18 years in a rural community in Maharashtra, India. In the context of key cultural factors, including gender-related norms, we explore issues of sexual health and critically assess widely held beliefs that Indian parents are unwilling or unable to discuss sex-related topics with their children. Our findings suggest that despite communication barriers, e.g., lack of knowledge and cultural proscriptions, Indian families are interested in and willing to communicate about sex-related topics. Future research should seek to determine the viability of family-based HIV prevention interventions for Indian adolescents.

Will climate change affect insect pheromonal communication?

PubMed

Boullis, Antoine; Detrain, Claire; Francis, Frédéric; Verheggen, François J

2016-10-01

Understanding how climate change will affect species interactions is a challenge for all branches of ecology. We have only limited understanding of how increasing temperature and atmospheric CO 2 and O 3 levels will affect pheromone-mediated communication among insects. Based on the existing literature, we suggest that the entire process of pheromonal communication, from production to behavioural response, is likely to be impacted by increases in temperature and modifications to atmospheric CO 2 and O 3 levels. We argue that insect species relying on long-range chemical signals will be most impacted, because these signals will likely suffer from longer exposure to oxidative gases during dispersal. We provide future directions for research programmes investigating the consequences of climate change on insect pheromonal communication. Copyright © 2016 Elsevier Inc. All rights reserved.

Alena, Richard L.; Ossenfort, John; Lee, Charles; Walker, Edward; Stone, Thom

2004-01-01

The Mobile Exploration System Project (MEX) at NASA Ames Research Center has been conducting studies into hybrid communication networks for future planetary missions. These networks consist of space-based communication assets connected to ground-based Internets and planetary surface-based mobile wireless networks. These hybrid mobile networks have been deployed in rugged field locations in the American desert and the Canadian arctic for support of science and simulation activities on at least six occasions. This work has been conducted over the past five years resulting in evolving architectural complexity, improved component characteristics and better analysis and test methods. A rich set of data and techniques have resulted from the development and field testing of the communication network during field expeditions such as the Haughton Mars Project and NASA Mobile Agents Project.

The iconicity of picture communication symbols for children with English additional language and mild intellectual disability.

PubMed

Dada, Shakila; Huguet, Alice; Bornman, Juan

2013-12-01

The purpose of this study was to examine the iconicity of 16 Picture Communication Symbols (PCS) presented on a themed bed-making communication overlay for South African children with English as an additional language and mild intellectual disability. The survey involved 30 participants. The results indicated that, overall, the 16 symbols were relatively iconic to the participants. The authors suggest that the iconicity of picture symbols could be manipulated, enhanced, and influenced by contextual effects (other PCS used simultaneously on the communication overlay). In addition, selection of non-target PCS for target PCS were discussed in terms of postulated differences in terms of distinctiveness. Potential clinical implications and limitations of the study, as well as recommendations for future research, are discussed.

Communication interventions for childhood vaccination are promising strategies to address vaccine hesitancy, but current research is limited by the outcomes measured. Most studies measure only vaccination-related outcomes, with minimal consideration of vaccine hesitancy-relevant intermediate outcomes. This impedes understanding of which interventions or elements are effective. It is also unknown which outcomes are important to the range of stakeholders affected by vaccine hesitancy. Outcome selection shapes the evidence base, informing future interventions and trials, and should reflect stakeholder priorities. Therefore, our aim was to identify which outcome domains (i.e. broad outcome categories) are most important to different stakeholders, identifying preliminary core outcome domains to inform evaluation of three common vaccination communication types: (i) communication to inform or educate, (ii) remind or recall, and (iii) enhance community ownership. We conducted a two-stage online Delphi survey, involving four stakeholder groups: parents or community members, healthcare providers, researchers, and government or non-governmental organisation representatives. Participants rated the importance of eight outcome domains for each of the three communication types. They also rated specific outcomes within one domain ("attitudes or beliefs") and provided feedback about the survey. Collectively, stakeholder groups prioritised outcome domains differently when considering the effects of different communication types. For communication that aims to (i) inform or educate, the most important outcome domain is "knowledge or understanding"; for (ii) reminder communication, "vaccination status and behaviours"; and for (iii) community engagement communication, "community participation". All stakeholder groups rated most outcome domains as very important or critical. The highest rated specific outcome within the "attitudes or beliefs" domain was "trust". This Delphi survey expands the field of core outcomes research and identifies preliminary core outcome domains for measuring the effects of communication about childhood vaccination. The findings support the argument that vaccination communication is not a single homogenous intervention - it has a range of purposes, and vaccination communication evaluators should select outcomes accordingly.

2017-12-01

The purpose of this review is to determine the scope of peer-reviewed empirical research related to counselling in audiology with patients using hearing technology and to identify limitations and gaps to guide recommendations for future research. A rapid evidence assessment was used to identify relevant articles for the review. Eighteen articles met the inclusion criteria. Three themes were identified: (1) audiologist counselling perspectives, (2) counselling communication trends in practice and (3) audiologist experiences with professional training and reported patient outcomes. Findings revealed audiologists are more confident providing information than counselling that addresses adjustment aspects, and other communication gaps have been observed. There is limited research related to counselling in audiology. Audiologists continue to report a need for more training in counselling in their graduate programmes. Additional research is needed to determine effective ways to implement counselling in practice and to improve graduate student supervision for the development of counselling competencies and confidence in using skills in practice.

Accurate knowledge and understanding of data link traffic loads that will have an impact on the underlying communications infrastructure within the National Airspace System (NAS) is of paramount importance for planning, development and fielding of future airborne and ground-based communications systems. Attempting to better understand this impact, NASA Glenn Research Center (GRC), through its contractor Computer Networks & Software, Inc. (CNS, Inc.), has developed an emulation and test facility known as the Virtual Aircraft and Controller (VAC) to study data link interactions and the capacity of the NAS to support Controller Pilot Data Link Communications (CPDLC) traffic. The drawback of the current VAC test bed is that it does not allow the test personnel and researchers to present a real world RF environment to a complex airborne or ground system. Fortunately, the United States Air Force and Navy Avionics Test Commands, through its contractor ViaSat, Inc., have developed the Joint Communications Simulator (JCS) to provide communications band test and simulation capability for the RF spectrum through 18 GHz including Communications, Navigation, and Identification and Surveillance functions. In this paper, we are proposing the development of a new and robust test bed that will leverage on the existing NASA GRC's VAC and the Air Force and Navy Commands JCS systems capabilities and functionalities. The proposed NASA Glenn Research Center's Aeronautical Networks Research Simulator (ANRS) will combine current Air Traffic Control applications and physical RF stimulation into an integrated system capable of emulating data transmission behaviors including propagation delay, physical protocol delay, transmission failure and channel interference. The ANRS will provide a simulation/stimulation tool and test bed environment that allow the researcher to predict the performance of various aeronautical network protocol standards and their associated waveforms under varying density conditions. The system allows the user to define human-interactive and scripted aircraft and controller models of various standards, such as (but not limited to) Very High Frequency Digital Link (VDL) of various modes.

Consumer health information seeking on the Internet: the state of the art.

PubMed

Cline, R J; Haynes, K M

2001-12-01

Increasingly, consumers engage in health information seeking via the Internet. Taking a communication perspective, this review argues why public health professionals should be concerned about the topic, considers potential benefits, synthesizes quality concerns, identifies criteria for evaluating online health information and critiques the literature. More than 70 000 websites disseminate health information; in excess of 50 million people seek health information online, with likely consequences for the health care system. The Internet offers widespread access to health information, and the advantages of interactivity, information tailoring and anonymity. However, access is inequitable and use is hindered further by navigational challenges due to numerous design features (e.g. disorganization, technical language and lack of permanence). Increasingly, critics question the quality of online health information; limited research indicates that much is inaccurate. Meager information-evaluation skills add to consumers' vulnerability, and reinforce the need for quality standards and widespread criteria for evaluating health information. Extant literature can be characterized as speculative, comprised of basic 'how to' presentations, with little empirical research. Future research needs to address the Internet as part of the larger health communication system and take advantage of incorporating extant communication concepts. Not only should research focus on the 'net-gap' and information quality, it also should address the inherently communicative and transactional quality of Internet use. Both interpersonal and mass communication concepts open avenues for investigation and understanding the influence of the Internet on health beliefs and behaviors, health care, medical outcomes, and the health care system.

In March 2014, GSK announced a number of new strategic investments in Africa. One of these included investment of up to 25 million Pounds Sterling (£25 million) to create the world's first R&D Open Lab to increase understanding of non-communicable diseases (NCDs) in Africa. The vision is to create a new global R&D effort with GSK working in partnership with major funders, academic centres and governments to share expertise and resources to conduct high-quality research. The Africa NCD Open Lab will see GSK scientists collaborate with scientific research centres across Africa. An independent advisory board of leading scientists and clinicians will provide input to develop the strategy and selection of NCD research projects within a dynamic and networked open-innovation environment. It is hoped that these research projects will inform prevention and treatment strategies in the future and will enable researchers across academia and industry to discover and develop new medicines to address the specific needs of African patients.

Risk communication and radiological/nuclear terrorism: a strategic view.

PubMed

Becker, Steven M

2011-11-01

It is now widely recognized that effective communication is a crucial element in radiological/nuclear terrorism preparedness. Whereas in the past, communication and information issues were sometimes viewed as secondary in comparison with technical concerns, today the need to improve risk communication, public information, and emergency messaging is seen as a high priority. The process of improving radiological/nuclear terrorism risk communication can be conceptualized as occurring in four overlapping phases. The first phase involves the recognition that communication and information issues will be pivotal in shaping how a radiological/nuclear terrorism incident unfolds and in determining its outcome. This recognition has helped shape the second phase, in which various research initiatives have been undertaken to provide an empirical basis for improved communication. In the third and most recent phase, government agencies, professional organizations and others have worked to translate research findings into better messages and informational materials. Like the first and second phases, the third phase is still unfolding. The fourth phase in risk communication for radiological/nuclear terrorism-a mature phase-is only now just beginning. Central to this phase is a developing understanding that for radiological/nuclear terrorism risk communication to be fully effective, it must go beyond crafting better messages and materials (as essential as that may be). This emerging fourth phase seeks to anchor radiological/nuclear communication in a broader approach: one that actively engages and partners with the public. In this article, each of the four stages is discussed, and future directions for improving radiological/nuclear terrorism risk communication are explored.

Evaluating public relations effectiveness in a health care setting. The identification of communication assets and liabilities via a communication audit.

Henderson, Julie K

2005-01-01

The practice of public relations has experienced tremendous growth and evolution over the past 25 years, especially in the area of medical public relations. The constant changes in health care delivery have often led to increased need for communication with important publics. At the same time, practitioners in all fields of public relations have explored methods of accurately measuring the effectiveness of public relations programs. One such method of evaluation is the communication audit. This paper includes a brief overview of the communication audit concept followed by a case study based on an audit conducted for a small, multicultural non-profit health-care agency. Steps taken to conduct the audit and the methodology used are discussed. An analysis of the data is used to address two research questions regarding the efficacy of the Center's mission and vision. Suggestions for future audits are provided.

Until the recent dissolution of the Soviet Union, the Communist Party exerted a strict control of access to and dissemination of scientific and technical information (STI). This article presents models of the Soviet-style information society and the Western-style information society and discusses the effects of centralized governmental control of information on Russian technical communication practices. The effects of political control on technical communication are then used to interpret the results of a survey of Russian and U.S. aerospace engineers and scientists concerning the time devoted to technical communication, their collaborative writing practices and their attitudes toward collaboration, the kinds of technical documents they produce and use, their views regarding the appropriate content for an undergraduate technical communication course, and their use of computer technology. Finally, the implications of these findings for future collaboration between Russian and U.S. engineers and scientists are examined.

Microanalysis research on 4-month mother-infant face-to-face communication operates like a “social microscope” and identifies aspects of maternal sensitivity and the origins of attachment with a more detailed lens. We hope to enhance a dialogue between these two paradigms, microanalysis of mother-infant communication and maternal sensitivity and emerging working models of attachment. The prediction of infant attachment from microanalytic approaches and their contribution to concepts of maternal sensitivity are described. We summarize aspects of one microanalytic study by Beebe and colleagues (2010) that documents new communication patterns between mothers and infants at 4 months that predict future disorganized (vs. secure) attachment. The microanalysis approach opens up a new window on the details of the micro-processes of face-to-face communication. It provides a new, rich set of behaviors with which to extend our understanding of the origins of infant attachment and of maternal sensitivity. PMID:24299136

People with severe neurological impairments face many challenges in sensorimotor functions and communication with the environment; therefore they have increased demand for advanced, adaptive and personalized rehabilitation. During the last several decades, numerous studies have developed brain–computer interfaces (BCIs) with the goals ranging from providing means of communication to functional rehabilitation. Here we review the research on non-invasive, electroencephalography (EEG)-based BCI systems for communication and rehabilitation. We focus on the approaches intended to help severely paralyzed and locked-in patients regain communication using three different BCI modalities: slow cortical potentials, sensorimotor rhythms and P300 potentials, as operational mechanisms. We also review BCI systems for restoration of motor function in patients with spinal cord injury and chronic stroke. We discuss the advantages and limitations of these approaches and the challenges that need to be addressed in the future. PMID:29472849

Parent-provider communication during hospitalization.

Parents and health care providers interact and communicate with each other during a child's hospitalization. The purpose of this study was to compare communication experiences of parents, nurses, and physicians. A unique aspect of this study involved combining three individual data sources into a collective unit of study (triad). Triads involved in the care of three children in the inpatient setting of an urban children's hospital served as the sample for this study (n = 10). Participants were asked semistructured questions during face-to-face interviews. Findings included (a) the importance of providing information by health care providers using a caring and inclusive approach, (b) the benefits of establishing interpersonal connections and nurturing relationships, and (c) the identification of specific behaviors in all members of the triad that contribute to and sustain positively perceived communication. Future research directions examining triadic interactions, communication, and relationships among parents, nurses, and physicians are recommended. Copyright © 2011 Elsevier Inc. All rights reserved.

This study employed an A-B singled subject design to explore the extent to which a peer-mediated intervention supported a first-grade student with autism's usage both in purpose and frequency of a speech-generating device (SGD) during mathematics activities. The intervention involved teaching a peer without a disability to encourage the student with autism to use the SGD during partnered mathematics activities. Our analysis involved visual and descriptive examination of trends and patterns over time, and comparison of means between and within phases. We found during the course of this study that (1) the student with autism's level of overall communication, which included the relevancy of these communicative behaviors, increased; (2) the student with autism's level of spontaneous communication acts increased; and (3) the peer became more independent with supporting the student with autism's communication. Implications for future research and practice are provided.

Dixon, Brian E; Gamache, Roland E; Grannis, Shaun J

2013-01-01

Objective To summarize the literature describing computer-based interventions aimed at improving bidirectional communication between clinical and public health. Materials and Methods A systematic review of English articles using MEDLINE and Google Scholar. Search terms included public health, epidemiology, electronic health records, decision support, expert systems, and decision-making. Only articles that described the communication of information regarding emerging health threats from public health agencies to clinicians or provider organizations were included. Each article was independently reviewed by two authors. Results Ten peer-reviewed articles highlight a nascent but promising area of research and practice related to alerting clinicians about emerging threats. Current literature suggests that additional research and development in bidirectional communication infrastructure should focus on defining a coherent architecture, improving interoperability, establishing clear governance, and creating usable systems that will effectively deliver targeted, specific information to clinicians in support of patient and population decision-making. Conclusions Increasingly available clinical information systems make it possible to deliver timely, relevant knowledge to frontline clinicians in support of population health. Future work should focus on developing a flexible, interoperable infrastructure for bidirectional communications capable of integrating public health knowledge into clinical systems and workflows.

2017-05-01

To systematically review the literature on the effectiveness of a patient coach intervention on patient - physician communication in specialists consultations. PubMed, Cochrane, PsycInfo, Cinahl and Embase were searched until November 2015. Included were papers describing interventions directed at adult outpatients in secondary care with a variety of somatic diseases. Outcomes had to be measured in communication effectivity from a patient's perspective. Seventeen publications met the inclusion criteria (involving 3787 patients), describing 13 unique interventions. Most interventions were single one-on-one sessions taking between 20 and 40min before consultation. Research quality in ten studies was high. These studies showed significant improvement on immediate, intermediate and long term patient - physician communication. We found limited evidence suggesting an improvement of patient - physician communication by having multiple patient coaching encounters during which questions are prepared and rehearsed and consultations are evaluated and reflected upon, sometimes supported by audio recording the consultation. The results of this review contribute to the (re-)design of an effective model for patient coaching, a profile and training approach of patient coaches. Future research should aim at determining which patients will benefit most from coaching interventions. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Ongoing research projects combined with user needs for weather related information are used to identify and describe potential weather products that address decision support in three time frames: Far-Term Strategic, Near-Term Strategic and Tactical. Data requirements of these future products are identified and quantified. Communications systems and technologies available in the public as well as private sector are analyzed to identify potential solutions. Recommendations for further research identify cost, performance, and safety benefits to justify the investment. The study concludes that not all weather information has the same level of urgency to safety-of-flight and some information is more critical to one category of flight than another. Specific weather products need to be matched with communication systems with appropriate levels of reliability to support the criticality of the information. Available bandwidth for highly critical information should be preserved and dedicated to safety. Meanwhile, systems designed for in-flight-entertainment and other passenger/crew services could be used to support less critical information that is used only for planning and economic decision support.

Research suggests that hurricane-related risk perception is a critical predictor of behavioral response, such as evacuation. Less is known, however, about the precursors of these subjective risk judgments, especially when time has elapsed from a focal event. Drawing broadly from the risk communication, social psychology, and natural hazards literature, and specifically from concepts adapted from the risk information seeking and processing model and the protective action decision model, we examine how individuals' distant recollections, including attribution of responsibility for the effects of a storm, attitude toward relevant information, and past hurricane experience, relate to risk judgment for a future, similar event. The present study reports on a survey involving U.S. residents in Connecticut, New Jersey, and New York (n = 619) impacted by Hurricane Sandy. While some results confirm past findings, such as that hurricane experience increases risk judgment, others suggest additional complexity, such as how various types of experience (e.g., having evacuated vs. having experienced losses) may heighten or attenuate individual-level judgments of responsibility. We suggest avenues for future research, as well as implications for federal agencies involved in severe weather/natural hazard forecasting and communication with public audiences. © 2017 Society for Risk Analysis.

People who are deaf use health care services differently than the general population; little research has been carried out to understand the reasons. To better understand the health care experiences of deaf people who communicate in American Sign Language. Qualitative analyses of focus group discussions in 3 U.S. cities. Ninety-one deaf adults who communicate primarily in American Sign Language. We collected information about health care communication and perceptions of clinicians' attitudes. We elicited stories of both positive and negative encounters, as well as recommendations for improving health care. Communication difficulties were ubiquitous. Fear, mistrust, and frustration were prominent in participants' descriptions of health care encounters. Positive experiences were characterized by the presence of medically experienced certified interpreters, health care practitioners with sign language skills, and practitioners who made an effort to improve communication. Many participants acknowledged limited knowledge of their legal rights and did not advocate for themselves. Some participants believed that health care practitioners should learn more about sociocultural aspects of deafness. Deaf people report difficulties using health care services. Physicians can facilitate change to improve this. Future research should explore the perspective of clinicians when working with deaf people, ways to improve communication, and the impact of programs that teach deaf people self-advocacy skills and about their legal rights.

The Radiation Problem and Its Solution from a Health Communication Perspective

PubMed Central

2016-01-01

This paper observes both foreign and national discussions on preexisting radiation communication and attempts to find out what it takes to ensure that discussion concerning radiation leads to participation of and trust-building with members of society while considering cultural aspects. When analyzing Korean studies on health risk communication concerning radiation which utilize the frame of foreign literature, Korean studies can be categorized into one of the following themes: different risk perceptions between experts and the general public, discussion on the effects of the framing of radiation messages and media coverage, and research discussing the social implications of the dangers of radiation and the need for effective communication. These study results can be better explained when integrated with Korean social cultural dimensions. The “boiling pot effect” towards risk issues, egalitarian perceptions, escalation of ideological opposition and biased reasoning, and so on are especially major influences. Communication addressing radiological risks must foremost be open and able to mitigate distrust, must give the general public a chance to judge for themselves to prevent stigmatization, and, through the use of media and public education, must make efforts to prevent the proliferation of needless anxiety. Using literature research, this paper discusses possible ways to improve the effect of future health risk communication concerning radiation. PMID:26908994

Recent years have seen convergence in research on brain mechanisms and neurocomputational approaches, culminating in the creation of a new generation of robots whose artificial "brains" respect neuroscience principles and whose "cognitive" systems venture into higher cognitive domains such as planning and action sequencing, complex object and concept processing, and language. The present article gives an overview of selected projects in this general multidisciplinary field. The work reviewed centres on research funded by the EU in the context of the New and Emergent Science and Technology, NEST, funding scheme highlighting the topic "What it means to be human". Examples of such projects include learning by imitation (Edici project), examining the origin of human rule-based reasoning (Far), studying the neural origins of language (Neurocom), exploring the evolutionary origins of the human mind (Pkb140404), researching into verbal and non-verbal communication (Refcom), using and interpreting signs (Sedsu), characterising human language by structural complexity (Chlasc), and representing abstract concepts (Abstract). Each of the communication-centred research projects revealed individual insights; however, there had been little overall analysis of results and hypotheses. In the Specific Support Action Nestcom, we proposed to analyse some NEST projects focusing on the central question "What it means to communicate" and to review, understand and integrate the results of previous communication-related research, in order to develop and communicate multimodal experimental hypotheses for investigation by future projects. The present special issue includes a range of papers on the interplay between neuroinformatics, brain science and robotics in the general area of higher cognitive functions and multimodal communication. These papers extend talks given at the NESTCOM workshops, at ICANN (http://www.his.sunderland.ac.uk/nestcom/workshop/icann.html) in Porto and at the first meeting of the Federation of the European Societies of Neuropsychology in Edinburgh in 2008 (http://www.his.sunderland.ac.uk/nestcom/workshop/esn.html). We hope that the collection will give a vivid insight into current trends in the field.

In response to growing interest in economic analyses of prevention efforts, a diverse group of prevention researchers, economists, and policy analysts convened a scientific panel, on “Research Priorities in Economic Analysis of Prevention” at the 19th annual conference of the Society for Prevention Research. The panel articulated four priorities that, if followed in future research, would make economic analyses of prevention efforts easier to compare and more relevant to policymakers, and community stakeholders. These priorities are: (1) increased standardization of evaluation methods, (2) improved economic valuation of common prevention outcomes, (3) expanded efforts to maximize evaluation generalizability and impact, as well as (4) enhanced transparency and communicability of economic evaluations. In this paper we define three types of economic analyses in prevention, provide context and rationale for these four priorities as well as related sub-priorities, and discuss the challenges inherent in meeting them.

This study examined the attitudes of children with typical development towards an unfamiliar peer with complex communication needs using augmentative and alternative communication (AAC) systems. Specifically, the study aimed to compare attitudes when the peer used mobile technology (i.e., iPad © 1 ) with an AAC-specific application (Proloquo2Go™ 2 ) versus a low-technology communication board. A within-group crossover design was utilized involving 78 children. Half of the participants (i.e., Group 1) viewed Video 1 of an unfamiliar peer with complex communication needs in a scripted communication interaction using an iPad with Proloquo2Go followed by Video 2 of the same interaction using a communication board. The other half of the participants (Group 2) viewed these videos in the reverse sequence. The Communication Aid/Device Attitudinal Questionnaire (CADAQ) was completed after watching each video. Results indicated that both groups were more positive towards Video 1 (iPad with Prologuo2Go) on certain dimensions of the CADAQ. The results are discussed and recommendations for future research provided.

Hispanic problem behavior youth are at an increased risk of engaging in HIV risk behaviors, including low condom use. However, relatively little research has examined factors that affect condom use in this population. Although research indicates that family processes, such as higher levels of family functioning and open parent-adolescent communication about sex, and condom use attitudes, norms, and control beliefs as depicted by the theory of planned behavior have an effect on condom use behaviors, the combination of the two factors has received minimal attention. The purpose of this study was to examine the effect of family functioning on condom use intentions and behaviors through communication about sex and condom use attitudes, parental norms, and control beliefs. A cross-sectional study of 171 predominately male (73.1%) sexually active Hispanic problem behavior adolescents (mean age = 14.88 years) was conducted. Structural equation modeling was used to test the study hypothesis. Findings largely support the overall model and suggest that family functioning had an indirect effect on condom use intention and behavior through communication about sex, condom use attitudes, and control beliefs. Family functioning, however, did not have an indirect effect on condom use intention and behavior through communication about sex and parental norms. Implications for prevention science and future research are discussed.

Interference Analysis for an Aeronautical Mobile Airport Communications System

The next generation of aeronautical communications for airport surface applications has been identified through a NASA research program and an international collaborative future communications study. The result, endorsed by both the United States and European regulatory agencies is called AeroMACS (Aeronautical Mobile Airport Communications System) and is based upon the IEEE 802.16e mobile wireless standard. Coordinated efforts to develop appropriate aviation standards for the AeroMACS system are now underway within RTCA (United States) and Eurocae (Europe). AeroMACS will be implemented in a recently allocated frequency band, 5091- 5150 MHz. As this band is also occupied by fixed satellite service uplinks, AeroMACS must be designed to avoid interference with this incumbent service. The aspects of AeroMACS operation that present potential interference to the fixed satellite service are under analysis in order to enable the definition of standards that assure that such interference will be avoided. The NASA Glenn Research Center has been involved in this analysis, and the first results of modeling and simulation efforts directed at this analysis are the subject of this paper.12

Communication systems in practice are subject to many technical/technological constraints and restrictions. Multiple input, multiple output (MIMO) processing in current wireless communications, as an example, mostly employs codebook-based pre-coding to save computational complexity at the transmitters and receivers. In such cases, closed form expressions for capacity or bit-error probability are often unattainable; effects of realistic signal processing algorithms on the performance of practical communication systems rather have to be studied in simulation environments. The Vienna LTE-A Uplink Simulator is a 3GPP LTE-A standard compliant MATLAB-based link level simulator that is publicly available under an academic use license, facilitating reproducible evaluations of signal processing algorithms and transceiver designs in wireless communications. This paper reviews research results that have been obtained by means of the Vienna LTE-A Uplink Simulator, highlights the effects of single-carrier frequency-division multiplexing (as the distinguishing feature to LTE-A downlink), extends known link adaptation concepts to uplink transmission, shows the implications of the uplink pilot pattern for gathering channel state information at the receiver and completes with possible future research directions.

Researchers have sought to understand the processes that may promote effective parent-adolescent communication because of the strong links to adolescent adjustment. Mindfulness, a relatively new construct in Western psychology that derives from ancient Eastern traditions, has been shown to facilitate communication and to be beneficial when applied in the parenting context. In this article, we tested if and how mindful parenting was linked to routine adolescent disclosure and parental solicitation within a longitudinal sample of rural and suburban, early adolescents and their mothers (n = 432; mean adolescent age = 12.14, 46 % male, 72 % Caucasian). We found that three factors-negative parental reactions to disclosure, adolescent feelings of parental over-control, and the affective quality of the parent-adolescent relationship-mediated the association between mindful parenting and adolescent disclosure and parental solicitation. Results suggest that mindful parenting may improve mother-adolescent communication by reducing parental negative reactions to information, adolescent perceptions of over-control, and by improving the affective quality of the parent-adolescent relationship. The discussion highlights intervention implications and future directions for research.

The identification of technologies necessary for development of millimeter spectrum communication satellites was examined from a system point of view. Development of methodology based on the technical requirements of potential services that might be assigned to millimeter wave bands for identifying the viable and appropriate technologies for future NASA millimeter research and development programs, and testing of this methodology with selected user applications and services were the goals of the program. The entire communications network, both ground and space subsystems was studied. Cost, weight, and performance models for the subsystems, conceptual design for point-to-point and broadcast communications satellites, and analytic relationships between subsystem parameters and an overall link performance are discussed along with baseline conceptual systems, sensitivity studies, model adjustment analyses, identification of critical technologies and their risks, and brief research and development program scenarios for the technologies judged to be moderate or extensive risks. Identification of technologies for millimeter satellite communication systems, and assessment of the relative risks of these technologies, was accomplished through subsystem modeling and link optimization for both point-to-point and broadcast applications.

Today, with the approach of the 21st century, attention is focused on multi-media communications combining computer, visual and audio technologies. This article discusses the communication media target and the technological problems constituting the nucleus of multi-media. The communication media is becoming an environment from which no one can escape. Since the media has such a great power, what is needed now is not to predict the future technologies, but to estimate the future world and take to responsibility for future environments.

With the plethora of information, there are many aspects to contested environments such as the protection of information, network privacy, and restricted observational and entry access. In this paper, we review and contrast the perspectives of challenges and opportunities for future developments in contested environments. The ability to operate in a contested environment would aid societal operations for highly congested areas with limited bandwidth such as transportation, the lack of communication and observations after a natural disaster, or planning for situations in which freedom of movement is restricted. Different perspectives were presented, but common themes included (1) Domain: targets and sensors, (2) network: communications, control, and social networks, and (3) user: human interaction and analytics. The paper serves as a summary and organization of the panel discussion as towards future concerns for research needs in contested environments.

[OMICS AND BIG DATA, MAJOR ADVANCES TOWARDS PERSONALIZED MEDICINE OF THE FUTURE?].

The increasing interest for personalized medicine evolves together with two major technological advances. First, the new-generation, rapid and less expensive, DNA sequencing method, combined with remarkable progresses in molecular biology leading to the post-genomic era (transcriptomics, proteomics, metabolomics). Second, the refinement of computing tools (IT), which allows the immediate analysis of a huge amount of data (especially, those resulting from the omics approaches) and, thus, creates a new universe for medical research, that of analyzed by computerized modelling. This article for scientific communication and popularization briefly describes the main advances in these two fields of interest. These technological progresses are combined with those occurring in communication, which makes possible the development of artificial intelligence. These major advances will most probably represent the grounds of the future personalized medicine.
