    Numerous studies show that exposure to entertainment-education-based mass media campaigns is associated with reduction in risk behaviors. Concurrently, there is a growing interest in comparing the cost-effectiveness of HIV prevention interventions taking into account infrastructural and programmatic costs. In such analyses, though few in number, mass media campaigns have fared well. Using data from a mass media communication campaign in the low HIV prevalence states of Uttar Pradesh, Rajasthan, and Delhi in Northern India, in this article we examine the following: (1) factors that mediate behavior change in different components of the campaign, comprising a TV drama, reality show for youth audiences, and TV spots; (2) the relative impact of campaign components on the behavioral outcome: condom use; and (3) the cost-effectiveness calculations arising from this analysis. Results suggest that recall of the TV spots and the TV drama influences behavior change and is strongly associated with interpersonal communication and positive gender attitudes. The TV drama, in spite of being the costliest, emerges as the most cost-effective component when considering the behavioral outcome of interest. The analysis of the comparative cost-effectiveness of individual campaign components provides insights into the planning of resources for communication interventions globally. PMID:17148103

    Three hepatobiliary agents with an acetanilide-imidoacetic-acid moiety resembling that in lidocaine were investigated for their possible effects on contractility and conductivity in the heart and on arterial pressure and aortic blood flow. This was done in the light of lidocaine's numerous cardiac side effects. HIDA, BIDA, and DIPA, each with traces of decayed /sup 99m/Tc, were injected i.v. into anesthetized dogs with an A-V block, and their effects on the above parameters were followed until control levels were reestablished. Whereas lidocaine raises the diastolic threshold and prolongs the refractory period, the three agents tested do not prolong myocardial conductivity. Both HIDA and BIDA have an effect similar to that of lidocaine, but DIPA has no effect on the latter two parameters. Moreover, whereas lidocaine depressed myocardial contractility, blood pressure, and blood flow, HIDA has a less prominent effect on these parameters, and neither BIDA nor DIPA has any such effect. It is concluded that even though the effect of HIDA on the heart is milder than that of lidocaine, the effects of both BIDA and DIPA are even less pronounced, and they are less likely to cause cardiac side effects when similar doses are administered during nuclear medicine procedures.

  16. State Synergies and Disease Surveillance: Creating an Electronic Health Data Communication Model for Cancer Reporting and Comparative Effectiveness Research in Kentucky

    PubMed Central

    Reams, Christopher; Powell, Mallory; Edwards, Rob

    2014-01-01

    Purpose: This case study describes the collaboration between a state public health department, a major research university, and a health extension service funded as part of the Health Information Technology for Economic and Clinical Health (HITECH) Act to establish an interoperable health information system for disease surveillance through electronic reporting of systemic therapy data from numerous oncology practices in Kentucky. The experience of the Kentucky cancer surveillance system can help local and state entities achieve greater effectiveness in designing communication efforts to increase usage of electronic health records (EHRs) and health information exchanges (HIEs), help eligible clinicians meet these new standards in patient care, and conduct disease surveillance in a learning health system. Innovation: We document and assess the statewide efforts of early health information technology (HIT) adopters in Kentucky to facilitate the nation’s first electronic transmission of a clinical document architecture (CDA) from a physician office to a state cancer surveillance registry in November 2012. Successful transmission of the CDA not only represented a landmark for technology innovators, informaticists, and clinicians, but it also set in motion a new communication mechanism by which state and federal agencies can capture and trade vital cancer statistics in a way that is safe, secure, and timely. The corresponding impact this has on cancer surveillance and comparative effective research is immense. With guidance from the Centers for Disease Control and Prevention (CDC), the Kentucky Cancer Registry (KCR), the Kentucky Health Information Exchange (KHIE), and the Kentucky Regional Extension Center (KREC) have moved one step further in transforming the interoperable health environment for improved disease surveillance. Credibility: This case study describes the efforts of established and reputable agencies, including the KCR, the state department of health

    The goal of comparative effectiveness research is to improve health care while dealing with the seemingly ever-rising cost. An understanding of comparative effectiveness research as a core topic is important for neuroradiologists. It can be used in a variety of ways. Its goal is to look at alternative methods of interacting with a clinical condition, ideally, while improving delivery of care. While the Patient-Centered Outcome Research initiative is the most mature US-based foray into comparative effectiveness research, it has been used more robustly in decision-making in other countries for quite some time. The National Institute for Health and Clinical Excellence of the United Kingdom is a noteworthy example of comparative effectiveness research in action. PMID:24874531

    2013-01-01

    Video recording has become increasingly popular in nursing research, adding rich nonverbal, contextual, and behavioral information. However, benefits of video over audio data have not been well established. We compared communication ratings of audio versus video data using the Emotional Tone Rating Scale. Twenty raters watched video clips of nursing care and rated staff communication on 12 descriptors that reflect dimensions of person-centered and controlling communication. Another group rated audio-only versions of the same clips. Interrater consistency was high within each group with ICC (2,1) for audio = .91, and video = .94. Interrater consistency for both groups combined was also high with ICC (2,1) for audio and video = .95. Communication ratings using audio and video data were highly correlated. The value of video being superior to audio recorded data should be evaluated in designing studies evaluating nursing care. PMID:23579475

    A strong interest and need exist in the workplace today to master the skills of conducting difficult conversations. Theories and strategies abound, yet none seem to have found the magic formula with universal appeal and success. If it is such an uncomfortable skill to master is it better to avoid or initiate such conversations with employees? Best practices and evidence-based management guide us to the decision that quality improvement dictates effective communication, even when difficult. This brief paper will offer some suggestions for strategies to manage difficult conversations with employees. Mastering the skills of conducting difficult conversations is clearly important to keeping lines of communication open and productive. Successful communication skills may actually help to avert confrontation through employee engagement, commitment and appropriate corresponding behavior PMID:23833841

    2008-08-01

    The successful ability to efficiently collect diet histories, convey appropriate health messages, and discuss client concerns about the safe feeding of pets requires excellent communication skills. In addition to understanding what the client wants for their pet, thorough nutritional interviewers gather information pertaining to animal factors, dietary factors, and feeding management factors. With the expansion of the Internet, increasing advances in medical care, and the health concerns associated with pet food recalls, small animal clients are looking to veterinarians for guidance and information on dietary recommendations in ever increasing numbers. Evaluating current information on changes in the pet food industry should be a periodic learning objective for all members of the veterinary health care team. Consistent, effective communication between veterinarians, their staff, and their clients can improve compliance, increase satisfaction levels, and improve patient outcomes. PMID:18656842

    Poor patient–provider interactions may play a role in explaining racial disparities in the quality and outcomes of HIV care in the United States. We analyzed 354 patient–provider encounters coded with the Roter Interaction Analysis System across four HIV care sites in the United States to explore possible racial differences in patient–provider communication. Providers were more verbally dominant in conversations with black as compared to white patients. This was largely due to black patients’ talking less than white patients. There was no association between race and other measures of communication. Black and white patients rated their providers’ communication similarly. Efforts to more effectively engage patients in the medical dialogue may lead to improved patient–provider relationships, self-management, and outcomes among black people living with HIV/AIDS.

  6. On Quantitative Comparative Research in Communication and Language Evolution

    PubMed Central

    Oller, D. Kimbrough; Griebel, Ulrike

    2014-01-01

    Quantitative comparison of human language and natural animal communication requires improved conceptualizations. We argue that an infrastructural approach to development and evolution incorporating an extended interpretation of the distinctions among illocution, perlocution, and meaning (Austin 1962; Oller and Griebel 2008) can help place the issues relevant to quantitative comparison in perspective. The approach can illuminate the controversy revolving around the notion of functional referentiality as applied to alarm calls, for example in the vervet monkey. We argue that referentiality offers a poor point of quantitative comparison across language and animal communication in the wild. Evidence shows that even newborn human cry could be deemed to show functional referentiality according to the criteria typically invoked by advocates of referentiality in animal communication. Exploring the essence of the idea of illocution, we illustrate an important realm of commonality among animal communication systems and human language, a commonality that opens the door to more productive, quantifiable comparisons. Finally, we delineate two examples of infrastructural communicative capabilities that should be particularly amenable to direct quantitative comparison across humans and our closest relatives.

    PubMed

    Garrett, J Hudson

    2016-08-01

    Breakdowns in health care communication are a significant cause of sentinel events and associated patient morbidity and mortality. Effective communication is a necessary component of a patient safety program, which enables all members of the interdisciplinary health care team to effectively manage their individual roles and responsibilities in the perioperative setting; set expectations for safe, high-reliability care; and measure and assess outcomes. To sustain a culture of safety, effective communication should be standardized, complete, clear, brief, and timely. Executive leadership and support helps remove institutional barriers and address challenges to support the engagement of patients in health care communication, which has been shown to improve outcomes, reduce costs, and improve the patient experience.

    The written word is the biomedical scientist's most important and most enduring communication tool. Nevertheless, the development of writing skills receives little attention in most scientific disciplines and the ability to conduct research is often viewed as more important than the ability to communicate the results of that research. Consequently, many scientists lack the writing skills necessary to effectively convey essential aspects of their research. In this paper, we will discuss the importance of good writing skills, give examples of common mistakes that are made in biomedical science writing and offer suggestions on how to improve written communication.

  12. Developing Effective Communications about Extreme Weather Risks.

    NASA Astrophysics Data System (ADS)

    Bruine de Bruin, W.

    2014-12-01

    Members of the general public often face complex decisions about the risks that they face, including those associated with extreme weather and climate change adaptation. Scientific experts may be asked to develop communications with the goal of improving people's understanding of weather and climate risks, and informing people's decisions about how to protect against these risks. Unfortunately, scientific experts' communication efforts may fail if they lack information about what people need or want to know to make more informed decisions or what wording people prefer use to describe relevant concepts. This presentation provides general principles for developing effective risk communication materials that aim for widespread dissemination, such as brochures and websites. After a brief review of the social science evidence on how to design effective risk communication materials, examples will focus on communications about extreme weather events and climate change. Specifically, data will be presented from ongoing projects on flood risk perception, public preparedness for heat waves, and public perceptions of climate change. The presentation will end with specific recommendations about how to improve recipients' understanding about risks and inform decisions. These recommendations should be useful to scientific experts who aim to communicate about extreme weather, climate change, or other risks.

  4. Effective Climate Communication with Difficult Audiences

    NASA Astrophysics Data System (ADS)

    Denning, S.

    2015-12-01

    Climate communication is often fraught with ideological baggage ("noise") that makes it very difficult to connect to audiences. In these cases, it is helpful to use "best practices" known from other fields of communication. Engaging audiences with authenticity, using plain language, respecting cultural and political differences, and a sprinkling of humor can go a long way toward establishing a connection. It's important to avoid common but polarizing tropes from popular media, and often quite helpful to frame climate issues in novel or unexpected ways that cut across entrenched political discourse. Emerging social science research Beyond ideology, climate change is Simple, Serious, and Solvable. Effective communication of these three key ideas can succeed when the science argument is carefully framed to avoid attack of the audience's ethical identity. Simple arguments from common sense and everyday experience are more successful than data. Serious consequences to values that resonate with the audience can be avoided by solutions that don't threaten those values.

    2009-04-01

    Scientific, technological and methodological knowledge regarding the risks caused by natural events are in continuous evolution. A careful analysis of the communication and information, practiced by administrations and institutions involved in the decision-making processes, show a peculiar difference between the quality of the theoretical-operating level and the effectiveness of communication systems of the risk obtained. This is the level which involves directly citizens and institutions and needs, therefore, an efficacious and shared system whose aim is to inform the whole community, in a simple and clear way, during the different phases correlated to the environmental risk. The hypotesis is, in fact, to create a distinct typology of message, corresponding to each phase: • prevention of the risk > sensitization > information. If the potential risk is imminent or changes into real emergency, it is necessary to plan a communication aimed at supporting a very fast alarm to the community. • anticipation of the risk > pre-alert > information • imminence of the risk > alert > alarm • post-event /risk > information > precept and rules. The lack of a uniform and coerent planning process, both on the linguistic field (the typology of the message, iconic and verbal) and technical (the typology of supports) it is clear analysing the reference scenario in Italy. This involves the creation of deeply discordant systems which don't communicate the different typologies of risk efficaciously during distinct moments. To come to a systemic vision of the problem we proceed to collect and to obtain documentation about the "alarm" and communication systems existing in Italy nowadays. So we will have a classification of the different typologies about natural risk and communication systems related to them. The aim of this research is to propose a rationalization and a standard coding of signals. The logical conclusion of this course can be the creation of a national

    The first step in cheesemaking is the milk clotting process, in which κ-caseinolytic enzymes contribute to micelle precipitation. The best enzyme for this purpose is chymosin because of its high degree of specificity toward κ-casein. Although recombinant bovine chymosin is the most frequently used chymosin in the industry, new sources of recombinant chymosin, such as goat, camel, or buffalo, are now available. The present work represents a comparative study of 4 different recombinant chymosins (goat and buffalo chymosins expressed in Pichia pastoris, and bovine and camel chymosin expressed in Aspergillus niger). Recombinant goat chymosin exhibited the best catalytic efficiency compared with the buffalo, bovine, or camel recombinant enzymes. Moreover, recombinant goat chymosin exhibited the best specific proteolytic activity, a wider pH range of action, and a lower glycosylation degree than the other 3 enzymes. In conclusion, we propose that recombinant goat chymosin represents a serious alternative to recombinant bovine chymosin for use in the cheesemaking industry. PMID:22281325

    2012-12-01

    "Communicating Science: Tools for Scientists and Engineers" is a workshop program developed by AAAS to provide guidance and practice for scientists and engineers in communicating about science with public audiences. The program was launched at the 2008 AAAS Annual Meeting in Boston and has since provided 24 workshops for more than 1,500 scientist and engineer attendees at universities, science society meetings, and government agency labs around the United States. Each interactive workshop targets scientists and engineers specifically and has included content such as message development, defining audience, identifying opportunities for engaging the public, and practice with public presentations and cameras. The workshop format allows for collaborative learning through small-group discussion, resource sharing, and participation in critique of other participants' presentations. Continuous monitoring of the program includes on-site and online surveys and evaluation. On an assessment of workshops from 2008-2010, attendees reported that knowledge gained from the workshop helped in crafting messages about their scientific work for use in communicating with public audiences, and approximately 80 percent of respondents reported participation in communication with a public audience after attending the workshop. Through workshop content and feedback of participating scientists, this presentation will highlight some best practices and resources for scientists who want to take a proactive role in science communication.

    2015-01-01

    The benefits of applying comparative effectiveness research (CER) strategies to the management of cancer are important. As the incidence of cancer increases both in the United States and worldwide, accurate analysis of which tests and treatments should be applied in which situations is critical, both in terms of measurable and meaningful clinical outcomes and health care costs. In the last 20 years alone, multiple controversies have arisen in the diagnosis and treatment of primary and metastatic tumors of the liver, making the management of liver malignancies a prime example of CER. Contributing factors to the development of these controversies include improvements in molecular characterization of these diseases and technological advances in surgery and radiology. The relative speed of these advances has outpaced data from clinical trials, in turn making robust data to inform clinical practice lacking. Indeed, many of the current treatment recommendations for the management of liver malignancies are based primarily on retrospective data. We herein review select CER issues concerning select decision-making topics in the management of liver malignancies. PMID:25677025

    PubMed

    Carelock, J; Innerarity, S

    2001-02-01

    Critical incidents can be defined at sentinel events, critical patient care issues, or any patient event outside the normal parameters of care. Nurses are central to maintaining the standard of care for patients in these situations. Miscommunication, including inadequate communication and illegible or incomplete documentation, forms a basis for many clinical and interpersonal problems in nursing practice. This practical article discusses expectations, both professional and legal, for avoiding and/or managing critical incidents. Suggestions for assessment parameters to report are included in table format, which the nurse can 'clip and use' as a reminder of data to have prepared before calling and/or presenting the problem. Steps are proposed for a logical, organized plan to help the nurse communicate more effectively. Recommendations for essentials of documentation regarding the verbal interaction and orders received are also presented. PMID:11852951

    2002-12-01

    In free-space optical (FSO) communications, conditions may be met when laser links suffer from solar background radiation (SBR). There are four types of such conditions Direct sunlight hitting a photodetector Reflected sunlight (glints) Sunlight scattered by hydrometeors Sunlight scattered by surrounding objects (walls, etc.) Direct sunlight may cause total break of communications (link outage), and thus affect the link availability. However, experiments prove that the sunlight does not cause irreversible degradation of semiconductor photodetectors used in FSO systems. Estimations are made of the link outage periods duration for various types of SBR conditions, also other effects caused by SBR have been considered. Recommendations are presented for the link directivity optimization to avoid (or to minimize the probability of) communication interrupts caused by SBR. A nomographic chart has been developed to forecast periods of time when direct or scattered solar radiation may cause link outage. With this chart, a user in any point of the globe, knowing the link orientation (azimuth and elevation angles), can see when and for how long (if at all) may the link operation be affected by unfavorable SBR conditions, also in many cases it is possible to recommend insignificant modifications in the link orientation causing material improvement in FSO system performance.

  16. Effect identification in comparative effectiveness research.

    PubMed

    Oakes, J Michael

    2013-01-01

    The widespread adoption of electronic medical records means there are now vast data resources available for comparative effectiveness research (CER). In concert with conventional randomized controlled trials, CER holds great promise for advancing our understanding of how different therapeutic treatments yield different health outcomes in different settings and with different populations. But in a research culture fixated on estimating correlations and p-values, the threat of misinterpretation of results and improper CER inferences is troubling. Accordingly, this paper aims to shore up the inferential foundations of CER by introducing the fundamentals of effect identification, which is the process of identifying or teasing out empirically defensible causal effects from competing explanations. Three primary requirements of effect identification-positivity, exchangeability, and consistency- are explained and simple exampled are given. The take home message is that so-called big data from medical records may not yield better or more useful results. Advances will come only when the right question is addressed with the appropriate data and methods. PMID:25848556

  19. Communication of medical product risk: how effective is effective enough?

    PubMed

    Goldman, Stephen A

    2004-01-01

    Ever-increasing attention is being paid worldwide to the safety of medical products, and the risks associated with their use. The integral role of risk communication in overall risk management is demonstrated by several recent market withdrawals of drugs, in which a perceived incapability of healthcare systems to manage well-characterised, avoidable risks was a significant factor. With advances in clinical pharmacology, pharmacogenomics and pharmacoepidemiology expanding our knowledge of medical products, effective delivery of the latest safety-related information to health professionals and consumers becomes even more imperative. In this regard, it is important to evaluate whether current modes of risk communication lead to desired changes in relevant behaviours such as prescribing or drug monitoring, particularly in context with which achieved level of effectiveness is deemed acceptable. This is crucial, as there have been product-specific risk communication efforts that achieved a fair degree of success, yet were not seen as effective enough to prevent market withdrawal of the medical product in question. In the service of improving public health through enhanced risk communication, it is essential to critically assess current methods, both as to results achieved (or not), and whether each method is applicable to the various types of risks associated with medical product use. Furthermore, just as combining methods may well improve overall risk communication, there are societal and psychological factors that must be considered in attempting to maximise effectiveness. However, in assessing risk communication effectiveness, the particular benefit- risk relationship of any individual medical product must also be part of the evaluative process. PMID:15154825

    The University of Texas at San Antonio (UTSA), San Antonio College (SAC), and the University of North Dakota (UND) have partnered with NASA to provide underrepresented undergraduates from UTSA, SAC, and other community colleges climate-related research and education experiences through the Climate Change Communication: Engineer, Environmental science, and Education (C3E3) project. The program aims to develop a robust response to climate change by providing K-16 climate change education; enhance the effectiveness of K-16 education particularly in engineering and other STEM disciplines by use of new instructional technologies; increase the enrollment in engineering programs and the number of engineering degrees awarded by showing engineering's usefulness in relation to the much-discussed contemporary issue of climate change; increase persistence in STEM degrees by providing student research opportunities; and increase the ethnic diversity of those receiving engineering degrees and help ensure an ethnically diverse response to climate change. Students participated in the second summer internship funded by the project. The program is in its third year. More than 75 students participated in a guided research experiences aligned with NASA Science Plan objectives for climate and Earth system science and the educational objectives of the three institutions. The students went through training in modern media technology (webcasts), and in using this technology to communicate the information on climate change to others, especially high school students, culminating in production of webcasts on investigating the aspects of climate change using NASA data. Content developed is leveraged by NASA Earth observation data and NASA Earth system models and tools. Three Colleges were involved in the program: Engineering, Education, and Science.

  10. Quantitative tools for comparing animal communication systems: information theory applied to bottlenose dolphin whistle repertoires.

    PubMed

    McCOWAN; Hanser; Doyle

    1999-02-01

    Comparative analysis of nonhuman animal communication systems and their complexity, particularly in comparison to human language, has been generally hampered by both a lack of sufficiently extensive data sets and appropriate analytic tools. Information theory measures provide an important quantitative tool for examining and comparing communication systems across species. In this paper we use the original application of information theory, that of statistical examination of a communication system's structure and organization. As an example of the utility of information theory to the analysis of animal communication systems, we applied a series of information theory statistics to a statistically categorized set of bottlenose dolphin Tursiops truncatus, whistle vocalizations. First, we use the first-order entropic relation in a Zipf-type diagram (Zipf 1949 Human Behavior and the Principle of Least Effort) to illustrate the application of temporal statistics as comparative indicators of repertoire complexity, and as possible predictive indicators of acquisition/learning in animal vocal repertoires. Second, we illustrate the need for more extensive temporal data sets when examining the higher entropic orders, indicative of higher levels of internal informational structure, of such vocalizations, which could begin to allow the statistical reconstruction of repertoire organization. Third, we propose using 'communication capacity' as a measure of the degree of temporal structure and complexity of statistical correlation, represented by the values of entropic order, as an objective tool for interspecies comparison of communication complexity. In doing so, we introduce a new comparative measure, the slope of Shannon entropies, and illustrate how it potentially can be used to compare the organizational complexity of vocal repertoires across a diversity of species. Finally, we illustrate the nature and predictive application of these higher-order entropies using a preliminary

  12. Effects of noise and task loading on a communication task loading on a communication task

    NASA Astrophysics Data System (ADS)

    Orrell, Dean H., II

    Previous research had shown the effect of noise on a single communication task. This research has been criticized as not being representative of a real world situation since subjects allocated all of their attention to only one task. In the present study, the effect of adding a loading task to a standard noise-communication paradigm was investigated. Subjects performed both a communication task (Modified Rhyme Test; House et al. 1965) and a short term memory task (Sternberg, 1969) in simulated levels of aircraft noise (95, 105 and 115 dB overall sound pressure level (OASPL)). Task loading was varied with Sternberg's task by requiring subjects to memorize one, four, or six alphanumeric characters. Simulated aircraft noise was varied between levels of 95, 105 and 115 dB OASPL using a pink noise source. Results show that the addition of Sternberg's task and little effect on the intelligibility of the communication task while response time for the communication task increased.

  14. Cue effectiveness in communicatively efficient discourse production.

    PubMed

    Qian, Ting; Jaeger, T Florian

    2012-01-01

    Recent years have seen a surge in accounts motivated by information theory that consider language production to be partially driven by a preference for communicative efficiency. Evidence from discourse production (i.e., production beyond the sentence level) has been argued to suggest that speakers distribute information across discourse so as to hold the conditional per-word entropy associated with each word constant, which would facilitate efficient information transfer (Genzel & Charniak, 2002). This hypothesis implies that the conditional (contextualized) probabilities of linguistic units affect speakers' preferences during production. Here, we extend this work in two ways. First, we explore how preceding cues are integrated into contextualized probabilities, a question which so far has received little to no attention. Specifically, we investigate how a cue's maximal informativity about upcoming words (the cue's effectiveness) decays as a function of the cue's recency. Based on properties of linguistic discourses as well as properties of human memory, we analytically derive a model of cue effectiveness decay and evaluate it against cross-linguistic data from 12 languages. Second, we relate the information theoretic accounts of discourse production to well-established mechanistic (activation-based) accounts: We relate contextualized probability distributions over words to their relative activation in a lexical network given preceding discourse.

    Technological and cultural factors influence access to health information on the web in multifarious ways. We evaluated structural differences and availability of communication services on the web in three diverse language and cultural groups: Chinese, English, and Spanish. A total of 382 web sites were analyzed: 144 were English language sites (38%), 129 were Chinese language sites (34%), and 108 were Spanish language sites (28%). We did not find technical differences in the number of outgoing links per domain or the total availability of communication services between the three groups. There were differences in the distribution of available services between Chinese and English sites. In the Chinese sites, there were more communication services between consumers and health experts. Our results suggest that the health-related web presence of these three cultural groups is technologically comparable, but reflects differences that may be attributable to cultural factors.

    Objective The aim of this study was to assess the accuracy of thin slices to characterize the verbal communication behavior of counselors and patients engaged in Motivational Interviewing sessions relative to fully coded sessions. Methods Four thin slice samples that varied in number (four versus six slices) and duration (one- versus two-minutes) were extracted from a previously coded dataset. In the parent study, an observational code scheme was used to characterize specific counselor and patient verbal communication behaviors. For the current study, we compared the frequency of communication codes and the correlations among the full dataset and each thin slice sample. Results Both the proportion of communication codes and strength of the correlation demonstrated the highest degree of accuracy when a greater number (i.e., six versus four) and duration (i.e., two- versus one-minute) of slices were extracted. Conclusion These results suggest that thin slice sampling may be a useful and accurate strategy to reduce coding burden when coding specific verbal communication behaviors within clinical encounters. Practice Implications We suggest researchers interested in using thin slice sampling in their own work conduct preliminary research to determine the number and duration of thin slices required to accurately characterize the behaviors of interest.

    Effective patient-provider communication is not a primary focus of medical school curricula. Motivational interviewing (MI) is a patient-centered, directive communication framework appropriate for in health care. Research on MI's causal mechanisms has established patient change talk as a mediator of behavior change. Current MI research focuses on identifying which provider communication skills are responsible for evoking change talk. MI recommends informing, asking, and listening. Research provides evidence that asking for and reflecting patient change talk are effective communication strategies, but cautions providers to inform judiciously. Supporting a patient's decision making autonomy is an important strategy to promote health behaviors. PMID:27261548

  3. The development of pointing perception in infancy: effects of communicative signals on covert shifts of attention.

    PubMed

    Daum, Moritz M; Ulber, Julia; Gredebäck, Gustaf

    2013-10-01

    The present study aims to investigate the interplay of verbal and nonverbal communication with respect to infants' perception of pointing gestures. Infants were presented with still images of pointing hands (cue) in combination with an acoustic stimulus. The communicative content of this acoustic stimulus was varied from being human and communicative to artificial. Saccadic reaction times (SRTs) from the cue to a peripheral target were measured as an indicator of the modulation of covert attention. A significant cueing effect (facilitated SRTs for congruent compared with incongruent trials) was only present in a condition with additional communicative and referential speech. In addition, the size of the cueing effect increased the more human and communicative the acoustic stimulus was. This indicates a beneficial effect of verbal communication on the perception of nonverbal communicative pointing gestures, emphasizing the important role of verbal communication in facilitating social understanding across domains. These findings additionally suggest that human and communicative (ostensive) signals are not qualitatively different from other less social signals but just quantitatively the most attention grabbing among a number of other signals.

    2011-10-01

    Marketing managers continually struggle with how to maximize the effects of an integrated marketing communications strategy. The growing number of available communication outlets, as well as highly varying competitive landscapes, adds further complexity to this challenge. This empirical study examines the differential impact within a pharmaceutical market therapeutic category where both "push" and "pull" communication strategies operate on consumers and gatekeepers alike, in an atmosphere of unrelenting product innovation and broad competition. Furthermore, we explore how two contingency variables-(a) the competitive landscape, and (b) the product's length of time on the market-interact with these communication efforts and affect brand and category sales.

    This investigation examined the long term effect of Karate techniques training on communication of children with autism spectrum disorders (ASD). Thirty school aged children with ASD were randomly assigned to an exercise (n = 15) or a control group (n = 15). Participants in the exercise group were engaged in 14 weeks of Karate techniques training. Communication deficit at baseline, post-intervention (week 14), and at 1 month follow up were evaluated. Exercise group showed significant reduction in communication deficit compared to control group. Moreover, reduction in communication deficit in the exercise group at one month follow up remained unchanged compared to post-intervention time. We concluded that teaching Karate techniques to children with ASD leads to significant reduction in their communication deficit. PMID:26577688

    2015-01-01

    Background Families’ refusal to authorize solid organ donation contributes to the organ deficit in the United States. The importance of communication to reducing refusal to requests for solid organ donation at the bedside and thus increasing the supply of transplantable organs cannot be overstated. This research compares 2 versions of an innovative communication skills training program for organ procurement organization request staff, Communicating Effectively About Donation (CEaD), designed to improve the quantity and quality of organ donation discussions with family decision makers of deceased patients. Methods We conducted a parallel group randomized controlled trial of the CEaD intervention, comparing an online only version of the training (CEaD1) with the online version bolstered with in-person practice and feedback (CEaD2). Survey and interview data were collected from 1603 family decision makers and 273 requesters to assess the impact of both versions of the CEaD on requesters’ communication skills and behaviors; the rate of family authorization to solid organ donation was obtained from administrative data provided by 9 organ procurement organizations. Results Results revealed higher rates of authorization for requesters with less tenure (78% to 89%, P < 0.03) for both versions; however, CEaD1 also increased authorization rates for requesters with 3 or more years of experience (89% to 92%, P < 0.03). Both conditions resulted in an improvement in overall communication quality. Conclusions We conclude that the CEaD was effective in improving requesters’ communication skills, rates of family authorization to organ donation, and the overall quality of the donation experience.

  4. Comparative effectiveness regulations and pharmaceutical innovation.

    PubMed

    Vernon, John A; Golec, Joseph H; Stevens, J Stedman

    2010-01-01

    As healthcare reform evolves and takes shape, comparative effectiveness research (CER) appears to be one of the central topics on the national healthcare agenda. Over the past couple of years, comparative effectiveness has been explicitly incorporated in more than ten bills. For example, the passage of the American Recovery and Reinvestment Act of 2009 authorized $US1.1 billion for CER. Comparative effectiveness, when costs are formally considered, offers the hope of efficient resource allocation within US healthcare markets. However, the future operationalization and implementation of comparative effectiveness is uncertain, and there exist potentially negative, and unintended, consequences under certain scenarios. One example, and the focus of this article, is pharmaceutical innovation. Incentives for pharmaceutical R&D could be affected if drug development costs increase as a result of firms having to bear, directly or indirectly, the costs of running larger, randomized, head-to-head comparative effectiveness trials. While this may or may not be the case with current and future comparative effectiveness legislation and its subsequent implementation, the potential consequences for pharmaceutical innovation warrant recognition. This is the purpose of the article. To achieve this goal, we develop several models of clinical trial design, drug development costs and R&D investment. By example, we shed light on the causal links between the models and the ways in which industry R&D investment can be affected. PMID:20831295

    2011-01-01

    Following an acrimonious health care reform debate involving charges of "death panels," in 2010, Congress explicitly forbade the use of cost-effectiveness analysis in government programs of the Patient Protection and Affordable Care Act. In this context, comparative effectiveness research emerged as an alternative strategy to understand better what works in health care. Put simply, comparative effectiveness research compares the efficacy of two or more diagnostic tests, treatments, or health care delivery methods without any explicit consideration of costs. To economists, the omission of costs from an assessment might seem nonsensical, but we argue that comparative effectiveness research still holds promise. First, it sidesteps one problem facing cost-effectiveness analysis--the widespread political resistance to the idea of using prices in health care. Second, there is little or no evidence on comparative effectiveness for a vast array of treatments: for example, we don't know whether proton-beam therapy, a very expensive treatment for prostate cancer (which requires building a cyclotron and a facility the size of a football field) offers any advantage over conventional approaches. Most drug studies compare new drugs to placebos, rather than "head-to-head" with other drugs on the market, leaving a vacuum as to which drug works best. Finally, the comparative effectiveness research can prove a useful first step even in the absence of cost information if it provides key estimates of treatment effects. After all, such effects are typically expensive to determine and require years or even decades of data. Costs are much easier to measure, and can be appended at a later date as financial Armageddon draws closer. PMID:21595324

    2015-05-01

    Three experiments explore several factors which influence information transmission when warning messages are passed from person to person. In Experiment 1, messages were passed down chains of participants using five different modes of communication. Written communication channels resulted in more accurate message transmission than verbal. In addition, some elements of the message endured further down the chain than others. Experiment 2 largely replicated these effects and also demonstrated that simple repetition of a message eliminated differences between written and spoken communication. In a final field experiment, chains of participants passed information however they wanted to, with the proviso that half of the chains could not use telephones. Here, the lack of ability to use a telephone did not affect accuracy, but did slow down the speed of transmission from the recipient of the message to the last person in the chain. Implications of the findings for crisis and emergency risk communication are discussed. PMID:25683552

    Objective Adolescent weight control interventions demonstrate variable findings, with inconsistent data regarding the appropriate role for parents. The current study examined the efficacy of a standard adolescent behavioral weight control (BWC) intervention that also targeted parent–adolescent communication and parental modeling of healthy behaviors (Standard Behavioral Treatment + Enhanced Parenting; SBT + EP) compared with a standard BWC intervention (SBT). Methods 49 obese adolescents (M age = 15.10; SD = 1.33; 76% female; 67.3% non-Hispanic White) and a caregiver were randomly assigned to SBT or SBT + EP. Adolescent and caregiver weight and height, parental modeling, and weight-related communication were obtained at baseline and end of the 16-week intervention. Results Significant decreases in adolescent weight and increases in parental self-monitoring were observed across both conditions. Analyses of covariance revealed a trend for greater reduction in weight and negative maternal commentary among SBT condition participants. Conclusions Contrary to hypotheses, targeting parent–adolescent communication and parental modeling did not lead to better outcomes in adolescent weight control. PMID:25294840

    2015-01-01

    The purpose of this study was to conduct a systematic review and meta-analysis of the augmentative and alternative communication (AAC) partner instruction intervention literature to determine (a) the overall effects of partner interventions on the communication of individuals using AAC, and (b) any possible moderating variables relating to participant, intervention, or outcome characteristics. Seventeen single-case experimental design studies (53 participants) met the inclusion criteria and were advanced to the full coding and analysis phase of the investigation. Descriptive analyses and effect size estimations using the Improvement Rate Difference (IRD) metric were conducted. Overall, communication partner interventions were found to be highly effective across a range of participants using AAC, intervention approaches, and outcome measure characteristics, with more evidence available for participants less than 12 years of age, most of whom had a diagnosis of autism spectrum disorder or intellectual/developmental disability. Aided AAC modeling, expectant delay, and open-ended question asking were the most frequently targeted communication partner interaction skills. Providing a descriptive overview, instructor modeling, guided practice, and role plays were the most frequently incorporated communication partner intervention activities within the included studies.

  11. Comparing Learning Gains: Audio Versus Text-based Instructor Communication in a Blended Online Learning Environment

    NASA Astrophysics Data System (ADS)

    Shimizu, Dominique

    Though blended course audio feedback has been associated with several measures of course satisfaction at the postsecondary and graduate levels compared to text feedback, it may take longer to prepare and positive results are largely unverified in K-12 literature. The purpose of this quantitative study was to investigate the time investment and learning impact of audio communications with 228 secondary students in a blended online learning biology unit at a central Florida public high school. A short, individualized audio message regarding the student's progress was given to each student in the audio group; similar text-based messages were given to each student in the text-based group on the same schedule; a control got no feedback. A pretest and posttest were employed to measure learning gains in the three groups. To compare the learning gains in two types of feedback with each other and to no feedback, a controlled, randomized, experimental design was implemented. In addition, the creation and posting of audio and text feedback communications were timed in order to assess whether audio feedback took longer to produce than text only feedback. While audio feedback communications did take longer to create and post, there was no difference between learning gains as measured by posttest scores when student received audio, text-based, or no feedback. Future studies using a similar randomized, controlled experimental design are recommended to verify these results and test whether the trend holds in a broader range of subjects, over different time frames, and using a variety of assessment types to measure student learning.

    The digital revolution affects the environment on several levels. Most directly, information and communications technology (ICT) has environmental impacts through the manufacturing, operation and disposal of devices and network equipment, but it also provides ways to mitigate energy use, for example through smart buildings and teleworking. At a broader system level, ICTs influence economic growth and bring about technological and societal change. Managing the direct impacts of ICTs is more complex than just producing efficient devices, owing to the energetically expensive manufacturing process, and the increasing proliferation of devices needs to be taken into account.

    A block based, automatic partitioning and scheduling methodology is presented for sparse matrix factorization on distributed memory systems. Using experimental results, this technique is analyzed for communication and load imbalance overhead. To study the performance effects, these overheads were compared with those obtained from a straightforward 'wrap mapped' column assignment scheme. All experimental results were obtained using test sparse matrices from the Harwell-Boeing data set. The results show that there is a communication and load balance tradeoff. The block based method results in lower communication cost whereas the wrap mapped scheme gives better load balance.

    Too often, strategic communication is too little, or comes too late, when involved with a child fatality or serious injury. This article explores the challenges arising from negative publicity around child safety issues and the opportunities for communications strategies that employ a proactive public health approach to engaging media, policymakers, and the public. The authors provide a case study and review methods by which child welfare agencies across the nation are building public engagement and support for improved outcomes in child safety while protecting legitimate confidentiality requirements. Finally, the piece articulates the rationale for agency investments in the resources necessary to develop and implement an effective communications plan. PMID:24199331

    The present investigation is concerned with the possibility to reduce the costs for placing satellites in orbit by making use of an 'Air Launch' system. It is pointed out that the launching of rockets to orbit from aircraft in flight has been done successfully. It is suggested to modify the existing technology for the purpose of launching communications satellites and other payloads to orbit. Thus, the Air Launch Concept combines aircraft and missile technologies to produce a method of transport to orbit. A heavy lift cargo aircraft is employed to fly a rocket and the satellite payload to a specific location at the service ceiling of the aircraft. Attention is given to aspects of cost reduction, commercial and technical benefits, the anticipated market, and technical details.

    The effect of noise on various protocols of secure quantum communication has been studied. Specifically, we have investigated the effect of amplitude damping, phase damping, squeezed generalized amplitude damping, Pauli type as well as various collective noise models on the protocols of quantum key distribution, quantum key agreement, quantum secure direct quantum communication and quantum dialogue. From each type of protocol of secure quantum communication, we have chosen two protocols for our comparative study: one based on single-qubit states and the other one on entangled states. The comparative study reported here has revealed that single-qubit-based schemes are generally found to perform better in the presence of amplitude damping, phase damping, squeezed generalized amplitude damping noises, while entanglement-based protocols turn out to be preferable in the presence of collective noises. It is also observed that the effect of noise depends upon the number of rounds of quantum communication involved in a scheme of quantum communication. Further, it is observed that squeezing, a completely quantum mechanical resource present in the squeezed generalized amplitude channel, can be used in a beneficial way as it may yield higher fidelity compared to the corresponding zero squeezing case.

    A detailed study of the performance effects of irregular communications patterns on the CM-2 was conducted. The communications capabilities of the CM-2 were characterized under a variety of controlled conditions. In the process of carrying out the performance evaluation, extensive use was made of a parameterized synthetic mesh. In addition, timings with unstructured meshes generated for aerodynamic codes and a set of sparse matrices with banded patterns on non-zeroes were performed. This benchmarking suite stresses the communications capabilities of the CM-2 in a range of different ways. Benchmark results demonstrate that it is possible to make effective use of much of the massive concurrency available in the communications network.

    ionosphere using IRI-Plas-G software. One of the outstanding features of IONOLAB-RAY is the opportunity of Global Ionospheric Map-Total Electron Content (GIM-TEC) assimilation. This feature enables more realistic representation of ionosphere, especially for the times when ionosphere deviates from the generalized models, such as during geomagnetic storms. This feature is critical to examine the effect of ionosphere on satellite signals under ionospheric storm conditions. In this study TURKSAT satellite data is used to compare the results of IONOLAB-RAY and evaluate the effect of ionosphere. TURKSAT is one of the world's leading companies providing all sorts of satellite communications through the satellites of TURKSAT as well as the other satellites. Providing services for voice, data, internet, TV, and radio broadcasting through the satellites across a wide area extending from Europe to Asia. The latest satellite of TURKSAT, namely Turksat 4B was launched on October 2015, before that various versions of TURKSAT satellites are launched since 1994. In the future enlargement of broadcasting area towards equatorial region is aimed, where the ionospheric anomalies and storms are highly expected. In the future this study can be applied to the satellite signals in equatorial regions and effects of ionosphere especially under storm conditions can be discussed. This study is supported by TUBITAK 114E541, 115E915 and Joint TUBITAK 114E092 and AS CR 14/001 projects.

    between ambient noise level and source level was identified. The Lombard effect, the increase in source level in response to an increase in noise level has not previously been identified in any pinniped species. In both datasets, an increase of approximately 5 dB in source level was found for an increase in 10 dB of noise level. A propagation experiment was conducted to measure the transmission of an impulsive acoustic signal, similar to a walrus knock, from an underwater source through ice and into air. Peak to peak pressure measured in air was approximately 2,500 times lower than pressure measured in water separated by two meters of shorefast ice. The results from this experiment were used to verify the adequacy of a wavenumber integration acoustic propagation model for determining transmission loss in this multi-media environment. Propagation model environments were generated from historical ice thickness and oceanographic data. Modeled received signals were compared with walrus audiometric data to determine what factors impact signal detectability with source level, ice thickness, and range having the greatest impact. The findings of this work suggest that the underwater vocalizations of males making breeding vocalizations are received by females hauled out on ice at audible levels when the females are within a few hundred meters of the males. As the signals exceed the levels estimated to be perceived, these signals may play a role in mate selection by the females. If climate change affects the ice conditions, water depth, and bathymetry where walrus congregate for breeding, mate selection and therefore offspring fitness may be impacted.

    Introduction. The link between patient-clinician communication and its effect on clinical outcomes is an important clinical issue that is yet to be elucidated. Objective. Investigating if communication type (positive or neutral) about the expected treatment outcome affected (i) participants' expectations and (ii) short-term relaxation effects in response to genuine or sham acupuncture and investigating if expectations were related to outcome. Methods. Healthy volunteers (n = 243, mean age of 42) were randomized to one treatment with genuine or sham acupuncture. Within groups, participants were randomized to positive or neutral communication, regarding expected treatment effects. Visual Analogue Scales (0–100 millimeters) were used to measure treatment expectations and relaxation, directly before and after treatment. Results. Participants in the positive communication group reported higher treatment expectancy, compared to the neutral communication group (md 12 versus 6 mm, p = 0.002). There was no difference in relaxation effects between acupuncture groups or between communication groups. Participants with high baseline expectancy perceived greater improvement in relaxation, compared to participants with low baseline levels (md 27 versus 15 mm, p = 0.022). Conclusion. Our data highlights the importance of expectations for treatment outcome and demonstrates that expectations can be effectively manipulated using a standardized protocol that in future research may be implemented in clinical trials.

    This article discusses the application of theories of argumentation and communication to the field of medicine. Based on a literature review, the authors compare Toulmin's model, pragma-dialectics, and the work of Todd and Fisher, derived from American sociolinguistics. These approaches were selected because they belong to the pragmatic field of language. The main results were: pragma-dialectics characterizes medical reasoning more comprehensively, highlighting specific elements of the three disciplines of argumentation: dialectics, rhetoric, and logic; Toulmin's model helps substantiate the declaration of diagnostic and therapeutic hypotheses, and as part of an interpretive medicine, approximates the pragma-dialectical approach by including dialectical elements in the process of formulating arguments; Fisher and Todd's approach allows characterizing, from a pragmatic analysis of speech acts, the degree of symmetry/asymmetry in the doctor-patient relationship, while arguing the possibility of negotiating treatment alternatives.

    The consequences of pandemic influenza for vulnerable populations will depend partly on the effectiveness of health risk communications. Strategic planning should fully consider how life circumstances, cultural values, and perspectives on risk influence behavior during a pandemic. We summarize recent scientific evidence on communication challenges and examine how sociocultural, economic, psychological, and health factors can jeopardize or facilitate public health interventions that require a cooperative public. If ignored, current communication gaps for vulnerable populations could result in unequal protection across society during an influenza pandemic. We offer insights on communication preparedness gleaned from scientific studies and the deliberations of public health experts at a meeting convened by the Centers for Disease Control and Prevention, May 1 and 2, 2008.

    The lack of good communication is a very real problem in mine emergencies. To counter communication breakdowns, researchers at the NIOSH Pittsburgh Research Laboratory developed the Emergency Communication Triangle. It is a training intervention designed to help those giving a warning to provide the right sort of information and those receiving a warning to ask the right questions. The Triangle has six ordered components with the first three considered most important. The Emergency Communication is packaged as a short safety talk to be given by supervisors at the start of a shift. It was first tested in 1998 with a group of 236 workers at an underground mine in Colorado, and proved effective. It was followed up in 2003 and again in 2004. Now, more than half the miners would report who was affected by an event, 60% would report in its severity, and 70% would say what had been done so far. 3 figs.

    This paper analyzes the lunar terrain effects on the signal propagation of the planned NASA lunar wireless communication and sensor systems. It is observed that the propagation characteristics are significantly affected by the presence of the lunar terrain. The obtained results indicate that the terrain geometry, antenna location, and lunar surface material are important factors determining the propagation characteristics of the lunar wireless communication systems. The path loss can be much more severe than the free space propagation and is greatly affected by the antenna height, operating frequency, and surface material. The analysis results from this paper are important for the lunar communication link margin analysis in determining the limits on the reliable communication range and radio frequency coverage performance at planned lunar base worksites.

    2011-02-01

    Research into emotional communication to date has largely focused on facial and vocal expressions. In contrast, recent studies by Hertenstein, Keltner, App, Bulleit, and Jaskolka (2006) and Hertenstein, Holmes, McCullough, and Keltner (2009) exploring nonverbal communication of emotion discovered that people could identify anger, disgust, fear, gratitude, happiness, love, sadness and sympathy from the experience of being touched on either the arm or body by a stranger, without seeing the touch. The study showed that strangers were unable to communicate the self-focused emotions embarrassment, envy and pride, or the universal emotion surprise. Literature relating to touch indicates that the interpretation of a tactile experience is significantly influenced by the relationship between the touchers (Coan, Schaefer, & Davidson, 2006). The present study compared the ability of romantic couples and strangers to communicate emotions solely via touch. Results showed that both strangers and romantic couples were able to communicate universal and prosocial emotions, whereas only romantic couples were able to communicate the self-focused emotions envy and pride.

    We have performed a study on telecommunication systems for a hypothetical mission to Mars. The objective of the study was to evaluate and compare the benefits that microwave-X-band (8.4 GHz) and Ka-band (32 GHz) - and optical communications technologies a afford to future missions. The telecommunication systems were required to return data after launch and in orbit at 2.7 AU with daily data volumes of 0.1, 1.0, or 10.0 Gbits (Gb). Spacecraft terminals capable of delivering each of the three data volumes were proposed and characterized in terms of mass, power consumption, size, and cost. The estimated parameters for X-band, Ka-band, and optical frequencies are compared and presented here. For all cases, the optical light terminal exhibits about 60 percent of the mass of the corresponding radio frequency (RF) subsystem. Power consumption is comparable for all three technologies at a 0.1 Gb/day data volume, but the power required at either Ka-band or optical is less than half of the X-band requirement at 10 Gb/day. These benefits can be obtained only with a suitable investment in reception facilities for Ka-band or optical frequencies.

    PubMed Central

    2011-01-01

    Background Mucosal infections elicit inflammatory responses via regulated signaling pathways. Infection outcome depends strongly on early events occurring immediately when bacteria start interacting with cells in the mucosal membrane. Hitherto reported transcription profiles on host-pathogen interactions are strongly biased towards in vitro studies. To detail the local in vivo genetic response to infection, we here profiled host gene expression in a recent experimental model that assures high spatial and temporal control of uropathogenic Escherichia coli (UPEC) infection within the kidney of a live rat. Results Transcriptional profiling of tissue biopsies from UPEC-infected kidney tissue revealed 59 differentially expressed genes 8 h post-infection. Their relevance for the infection process was supported by a Gene Ontology (GO) analysis. Early differential expression at 3 h and 5 h post-infection was of low statistical significance, which correlated to the low degree of infection. Comparative transcriptomics analysis of the 8 h data set and online available studies of early local infection and inflammation defined a core of 80 genes constituting a "General tissue response to early local bacterial infections". Among these, 25% were annotated as interferon-γ (IFN-γ) regulated. Subsequent experimental analyses confirmed a systemic increase of IFN-γ in rats with an ongoing local kidney infection, correlating to splenic, rather than renal Ifng induction and suggested this inter-organ communication to be mediated by interleukin (IL)-23. The use of comparative transcriptomics allowed expansion of the statistical data handling, whereby relevant data could also be extracted from the 5 h data set. Out of the 31 differentially expressed core genes, some represented specific 5 h responses, illustrating the value of comparative transcriptomics when studying the dynamic nature of gene regulation in response to infections. Conclusion Our hypothesis-free approach identified

    The effect of communicating social psychology research findings on ingroup bias in a classroom setting has been investigated. Two hundred and twenty one high school students either read or did not read a brief report about three classical social psychological studies, then completed evaluation scales for the ingroup and the outgroup. Participants' motivation was manipulated, and the messages were different as regards the congruency between the content and participants' actual intergroup experience. Results showed that communication exerted a significant effect in reducing ingroup bias for participants in the high motivation/high congruency condition, that is, the communication effect was moderated by the individual's level of motivation and the content of the arguments proposed in the report. Practical implications of results for education work and stereotype change, limitations of the study, as well as possible directions for future research are discussed. PMID:27247671

    2004-04-01

    The Idaho National Engineering and Environmental Laboratory (INEEL) received ISO 14001/EMS certification in June 2002. Communication played an effective role in implementing ISO 14001/EMS at the INEEL. This paper describes communication strategies used during the implementation and certification processes. The INEEL achieved Integrated Safety Management System (ISMS) and Voluntary Protection Program (VPP) Star status in 2001. ISMS implemented a formal process to plan and execute work. VPP facilitated worker involvement by establishing geographic units at various facilities with employee points of contact and management champions. The INEEL Environmental Management System (EMS) was developed to integrate the environmental functional area into its ISMS and VPP. Since the core functions of ISMS, VPP, and EMS are interchangeable, they were easy to integrate. Communication is essential to successfully implement an EMS. (According to ISO 14001 requirements, communication interacts with 12 other elements of the requirements.) We developed communication strategies that integrated ISMS, VPP, and EMS. For example, the ISMS, VPP, and EMS Web sites communicated messages to the work force, such as “VPP emphasizes the people side of doing business, ISMS emphasizes the system side of doing business, and EMS emphasizes the systems to protect the environment; but they all define work, identify and analyze hazards, and mitigate the hazards.” As a result of this integration, the work force supported and implemented the EMS. In addition, the INEEL established a cross-functional communication team to assist with implementing the EMS. The team included members from the Training and Communication organizations, VPP office, Pollution Prevention, Employee and Media Relations, a union representative, facility environmental support, and EMS staff. This crossfunctional team used various communication strategies to promote our EMS to all organization levels and successfully implemented EMS

  2. Commentary: Will academia embrace comparative effectiveness research?

    2011-06-01

    In recent medical history, a number of therapies that were widely adopted based on observational data or pathophysiological constructs turned out to be useless or even harmful when tested in randomized comparative effectiveness trials. These therapies not only harmed patients but also did a disservice to the practical education of medical students, residents, and fellows. These trainees effectively learned that it is acceptable to implement practices even in the absence of high-quality evidence, and so they may not have learned how to analyze the quality of evidence. In this issue of Academic Medicine, seven groups address critical aspects of the intersection between comparative effectiveness research (CER) and academic medicine. Their topics include the need at academic health centers for cultural shifts, for addressing conflicts of interest, for exploiting academic talent and electronic information resources, for interacting well with policy makers, for incorporating economic evaluations, for incorporating tests of educational methods, for developing multidisciplinary models, and for integrating CER into "predictive health." This commentary argues that academia must embrace CER by insisting on the highest levels of evidence, by viewing all clinical interactions as opportunities for scientific advancement, by setting an example for policy makers and colleagues working in nonacademic settings, and by engaging all physicians in the clinical research enterprise.

    Combat resiliency is the ability of a commander to prosecute, control, and consolidate his/her's sphere of influence in adverse and changing conditions. To support this, an infrastructure must exist that allows the commander to view the world in varying degrees of granularity with sufficient levels of detail to permit confidence estimates to be levied against decisions and course of actions. An infrastructure such as this will include the ability to effectively communicate context and relevance within and across the battle space. To achieve this will require careful thought, planning, and understanding of a network and its capacity limitations in post-event command and control. Relevance and impact on any existing infrastructure must be fully understood prior to deployment to exploit the system's full capacity and capabilities. In this view, the combat communication network is considered an integral part of or National communication network and infrastructure. This paper will describe an analytical tool set developed at ORNL and RNI incorporating complexity theory, advanced communications modeling, simulation, and visualization technologies that could be used as a pre-planning tool or post event reasoning application to support response and containment.

In conclusion, it seems that delinquent behavior is the outcome caused by dysfunctional communication between the parents and the child because of severe generation gap at adolescence period when the child needs communication with their parents. Therefore, it seems that the delinquent adolescent is the scape-goat of the family. Finally, it seems that more effective method to solve juvenile delinquents increasing day by day, is the family therapy that all family members participate than the individual therapy. PMID:2287168

    In the clinical research context, comparative effectiveness research (CER) refers to the comparison of several health-care interventions administered under real-world conditions to individuals representative of the day-to-day clinical practice target population. We provide a brief history of CER and argue that CER can be used to deliver useful, but currently lacking information. Three study designs that can accomplish this are discussed, and incorporating CER into cost-benefit analyses is examined. The relationships between CER and evidence-based and personalized medicine are also considered, as is the challenge of implementing CER results into routine clinical practice. PMID:25544326

    2008-01-01

    Adoption and family communication both affect adolescent adjustment. We proposed that adoption status and family communication interact such that adopted adolescents in families with certain communication patterns are at greater risk for adjustment problems. We tested this hypothesis using a community-based sample of 384 adoptive and 208 nonadoptive families. Adolescents in these families were, on average, 16 years of age. The results supported our hypothesis. Adopted adolescents were at significantly greater risk for adjustment problems compared to nonadopted adolescents in families that emphasized conformity orientation without conversation orientation and in families that emphasized neither conformity nor conversation orientation. Adolescents in families emphasizing conversation orientation were at lower risk for adjustment problems, regardless of adoption status. PMID:19649145

    2013-01-01

    Cell-to-cell communication is a prerequisite for differentiation and development in multicellular organisms. This communication has to be tightly regulated to ensure that cellular components such as organelles, macromolecules, hormones, or viruses leave the cell in a precisely organized way. During evolution, plants, animals, and fungi have developed similar ways of responding to this biological challenge. For example, in higher plants, plasmodesmata connect adjacent cells and allow communication to regulate differentiation and development. In animals, two main general structures that enable short- and long-range intercellular communication are known, namely gap junctions and tunneling nanotubes, respectively. Finally, filamentous fungi have also developed specialized structures called septal pores that allow intercellular communication via cytoplasmic flow. This review summarizes the underlying mechanisms for intercellular communication in these three eukaryotic groups and discusses its consequences for the regulation of differentiation and developmental processes.

    Hands Free Communication Device (HFCD) systems are a relatively new information and communication technology. HFCD systems enable clinicians to directly contact and communicate with one another using wearable, voice-controlled badges that are VoIP-based (voice-over IP) and are linked to one another over a wireless local area network (WLAN). This qualitative study utilized a grounded theory, multiple perspectives approach to understand how the use of HFCDs affected communication in the hospitals that implemented them. The study generated five themes revolving around HFCDs impact on communication. This paper specifically focuses on two of those themes: Communication Access and Control. PMID:18999046

  13. Communication: Memory effects and active Brownian diffusion

    A self-propelled artificial microswimmer is often modeled as a ballistic Brownian particle moving with constant speed aligned along one of its axis, but changing direction due to random collisions with the environment. Similarly to thermal noise, its angular randomization is described as a memoryless stochastic process. Here, we speculate that finite-time correlations in the orientational dynamics can affect the swimmer's diffusivity. To this purpose, we propose and solve two alternative models. In the first one, we simply assume that the environmental fluctuations governing the swimmer's propulsion are exponentially correlated in time, whereas in the second one, we account for possible damped fluctuations of the propulsion velocity around the swimmer's axis. The corresponding swimmer's diffusion constants are predicted to get, respectively, enhanced or suppressed upon increasing the model memory time. Possible consequences of this effect on the interpretation of the experimental data are discussed.

  1. Effective Communication with Cultural Heritage Using Virtual Technologies

    Cultural heritage is neither static nor stable. There is a need to explore ways for effectively communicating with cultural heritage to tourists and society at large, in an age of immediacy, a time of multiple realities and to multi-cultural tourists. It is vital to consider cultural heritage as a creative and relational process where places and communities are constantly remade through creative performance. The paper introduces virtual technologies as an approach to attain effective communication with cultural heritage. This approach emphasizes the importance of "user, content and context" in guiding the production of virtual heritage, as opposed to technology being the sole motivator. It addresses how these three issues in virtual heritage need to be transformed from merely representing quantitative data towards cultural information using the proposed effective communication triangle through representing meaningful relationships between cultural heritage elements, users and context. The paper offers a focused articulation of a proposed computational platform of "interactive, personalized and contextual-based navigation" with Egyptian heritage monuments as a one step forward towards achieving effective communication with Egyptian cultural heritage.

    Nonstandard gradients of pressure, temperatures and humidity in the troposphere create refractive conditions that affect electromagnetic waves by either increasing or decreasing VHF and UHF communication ranges. The Naval Ocean Systems Center (NOSC) has developed the Integrated Refractive Effect Prediction System (IREPS) to assess refractive conditions for a point of interest and provide video display or printouts of how the refractive conditions will affect various EM transmissions. A research cruise was conducted from 1 to 8 November 1989 in the Eastern Pacific and included 31 rawinsonde launches. The data from rawinsondes was entered in IREPS PC Version 1.0 assess the refractive conditions. The IREPS generated refractive assessments where then compared to the GTE Sylvania Report and the Pacific Missile Test Center's Interim Procedure for Forecasting Refractivity Conditions (IPFRC). The results indicated that the GTE Sylvania climatology was not an accurate tool for assessing refractive condition at sea mainly because the GTE data set consisted of shore-based rawinsonde data. The IPFRC, based solely on synoptic weather parameters, obtained at 60 percent success rate in predicting the likelihood of the presence of refractive conditions.

    Research examining the process of deciding between treatment alternatives, the applicability of the existing literature to this process, and the way that this knowledge can be applied to inform clinical decisions is termed comparative effectiveness research (CER). Despite its emerging role in both clinical medicine and public policy, many neurosurgeons are unaware of the history of CER, the principles fundamental to its implementation, and the nature and extent to which it impacts patient care. We present a review of literature that provides a brief history of the evolution of CER, an overview of its scientific, financial, and public policy implications, and a discussion of its implementation and potential significance in modern clinical practice. We discuss how CER seeks to combine treatment efficacy data with quality of life, outcomes, and other forms of effectiveness data to guide selection of optimal patient management strategies. This research paradigm strengthens the final step in clinical research that should follow the traditional demonstration of efficacy and reemphasizes the potentially important role of observational and retrospective investigations in establishing effectiveness of efficacious procedures in actual application to individual patients. It is useful for neurosurgeons to understand the CER model, because it occupies an emerging role in both clinical medicine and public policy and presents a potentially useful model for informing medical decision-making in the type of real-world situations commonly encountered by clinical neurosurgeons.

    We present a framework for evaluating and communicating effects of human activity on water quality in managed forests. The framework is based on the following processes: atmospheric deposition, weathering, accumulation, recirculation and flux. Impairments to water quality are characterized in terms of their extent, longevity and frequency. Impacts are communicated using a "traffic lights" metaphor for characterizing severity of water quality impairments arising from forestry and other anthropogenic pressures. The most serious impairments to water quality in managed boreal forests include (i) forestry activities causing excessive sediment mobilization and extirpation of aquatic species and (ii) other anthropogenic pressures caused by long-range transport of mercury and acidifying pollutants. The framework and tool presented here can help evaluate, summarize and communicate the most important issues in circumstances where land management and other anthropogenic pressures combine to impair water quality and may also assist in implementing the "polluter pays" principle.

    Recent research on communication and performance in airline flight crews has led to a concept of shared mental models that is associated with effective, efficient team coordination in problem solving and decision making situations. Elements that characterize efficient communication have been identified. This research, however, was based strictly on US crews. More recent studies supported by NASA have identified cultural factors that influence communication among team members who vary in their status and roles. Research is just beginning to identify commonalities and culturally distinct strategies for accomplishing joint tasks. ASRS incident reports have been analyzed to identify language barriers in flight that have safety consequences. Implications of these concepts and findings for multi-cultural command and control will be explored.

This data deluge, due primarily to the introduction of digitalization in routine medical care and medical research, affords the opportunity for improved patient care and scientific discovery. Medical informatics is the subdiscipline of medicine created to make greater use of information in order to improve healthcare. The 4 areas of medical informatics research (information access, structure, analysis, and interaction) are used as a framework to discuss the overlap in information needs of comparative effectiveness research and potential contributions of medical informatics. Examples of progress from the medical informatics literature and the Veterans Affairs Healthcare System are provided. PMID:21184865

    Communication is essential to safe flight, as evidenced by several accidents in which crew communicates was found to have contributed to the accidents. This chapter documents the essential role of explicit efficient communication to flight safety with a global context. It addresses communication between flight crews and air traffic controllers in regions a the world where pilots and controllers speak different native languages, as well as cases in which crew members within the flight deck represent different native languages and cultures. It also addresses problems associated with "exporting" crew resource management training programs to parts of the world which values and norms differ from those of the United States, where these programs were initially developed. This chapter is organized around several central questions: (1) What are various kinds of communication failures and what are their consequences; (2) What are the causes of communication failure; (3) What are features of effective crew communication; (4) What can be done to enhance communication success? To explore a wider range of communication failures than available from accident reports, we examined a set of incident reports from the Aviation Safety Reporting System. These could be classified into three major categories: those in which language actually interfered with transmission of a message; those in which transmission was adequate but the context was not expressed unambiguously and thus the message received was not the same as the message intended; and those in which the message was received as intended, but was not adequately understood or acted upon, mainly because of cultural factors. The consequences of failed communication can be flight errors (such as when a clearance is not received correctly), loss of situation awareness, or failure of crew members (or ATC and pilots) to build a shared understanding of a situation. Causes of misunderstanding can be traced to a number of sources, often

    Background The population of Japan has achieved the longest life expectancy in the world. To further improve population health, consistent and comparative evidence on mortality attributable to preventable risk factors is necessary for setting priorities for health policies and programs. Although several past studies have quantified the impact of individual risk factors in Japan, to our knowledge no study has assessed and compared the effects of multiple modifiable risk factors for non-communicable diseases and injuries using a standard framework. We estimated the effects of 16 risk factors on cause-specific deaths and life expectancy in Japan. Methods and Findings We obtained data on risk factor exposures from the National Health and Nutrition Survey and epidemiological studies, data on the number of cause-specific deaths from vital records adjusted for ill-defined codes, and data on relative risks from epidemiological studies and meta-analyses. We applied a comparative risk assessment framework to estimate effects of excess risks on deaths and life expectancy at age 40 y. In 2007, tobacco smoking and high blood pressure accounted for 129,000 deaths (95% CI: 115,000–154,000) and 104,000 deaths (95% CI: 86,000–119,000), respectively, followed by physical inactivity (52,000 deaths, 95% CI: 47,000–58,000), high blood glucose (34,000 deaths, 95% CI: 26,000–43,000), high dietary salt intake (34,000 deaths, 95% CI: 27,000–39,000), and alcohol use (31,000 deaths, 95% CI: 28,000–35,000). In recent decades, cancer mortality attributable to tobacco smoking has increased in the elderly, while stroke mortality attributable to high blood pressure has declined. Life expectancy at age 40 y in 2007 would have been extended by 1.4 y for both sexes (men, 95% CI: 1.3–1.6; women, 95% CI: 1.2–1.7) if exposures to multiple cardiovascular risk factors had been reduced to their optimal levels as determined by a theoretical-minimum-risk exposure distribution.

    Previous studies have shown that a communications program using patient instructors (PIs) facilitates data-gathering and interpersonal skills of third-year dental students. The aim of this study was to address the question of whether those skills are retained into the students' fourth year and generalized from the classroom to the clinic. In the formative training phase, three cohorts of D3 students (N=1,038) at one dental school received instruction regarding effective patient-doctor communication; interviewed three PIs and received PI feedback; and participated in a reflective seminar with a behavioral science instructor. In the follow-up competency phase, fourth-year students performed two new patient interviews in the clinic that were observed and evaluated by clinical dental faculty members trained in communications. Mean scores on a standardized communications rating scale and data-gathering assessment were compared over training and follow-up sessions and between cohorts with a linear mixed model. The analysis showed that the third-year students' mean communication and data-gathering scores increased with each additional encounter with a PI (p<0.05) and that communication scores were not only maintained but increased during the fourth-year follow-up competency evaluations (p<0.05). Based on changes in the communications curriculum, prior instruction facilitated the students' clinical communication performance at baseline (p<0.05). This study suggests that the current Clinical Communications program improved students' data-gathering and interpersonal skills. Those skills were maintained and generalized through completion of the D4 students' summative competency performance in a clinical setting. PMID:26246533

    Significance: Injury to the skin provides a unique challenge, as wound healing is a complex and intricate process. Acute wounds have the potential to move from the acute wound to chronic wounds, requiring the physician to have a thorough understanding of outside interventions to bring these wounds back into the healing cascade. Recent Advances: The development of new and effective interventions in wound care remains an area of intense research. Negative pressure wound therapy has undoubtedly changed wound care from this point forward and has proven beneficial for a variety of wounds. Hydroconductive dressings are another category that is emerging with studies underway. Other modalities such as hyperbaric oxygen, growth factors, biologic dressings, skin substitutes, and regenerative materials have also proven efficacious in advancing the wound-healing process through a variety of mechanisms. Critical Issues: There is an overwhelming amount of wound dressings available in the market. This implies the lack of full understanding of wound care and management. The point of using advanced dressings is to improve upon specific wound characteristics to bring it as close to "ideal" as possible. It is only after properly assessing the wound characteristics and obtaining knowledge about available products that the "ideal" dressing may be chosen. Future Directions: The future of wound healing at this point remains unknown. Few high-quality, randomized controlled trials evaluating wound dressings exist and do not clearly demonstrate superiority of many materials or categories. Comparative effectiveness research can be used as a tool to evaluate topical therapy for wound care moving into the future. Until further data emerge, education on the available products and logical clinical thought must prevail. PMID:25126472

    This study compares the results of code reading, functional testing, and structural testing in three aspects of software testing: fault detection effectiveness, fault detection cost, and classes of faults detected. Thirty two professional programmers and 42 advanced students applied the three techniques to four unit-sized programs in a fractional experimental design. The major results of this study are the following: (1) With the professional programmers, code reading detected more software faults and had a higher detection rate than did functional or structural testing, while functional testing detected more faults than did structural testing, but functional and structural testing were not different in fault detection rate. (2) In one advanced student subject group, code reading and functional testing were not different in faults found, but were superior to structural testing, while in the other advanced student subject group there was no difference among the techniques. (3) With the advanced student subjects, the three techniques were not different in fault deteciton rate. (4) Number of faults observed, fault detection rate, and total effort in detection depended on the type of software tested. (5) Code reading detected more interface faults than did the other methods. (6) Functional testing detected more control faults than did the other methods. (7) When asked to estimate the percentage of faults detected, code readers gave the most accurate estimates while functional testers gave the least accurate estimates.

    We describe the design and MPI implementation of two benchmarks created to characterize the balanced system performance of high-performance clusters and supercomputers: b{_}eff, the communication-specific benchmark examines the parallel message passing performance of a system, and b{_}eff{_}io, which characterizes the effective 1/0 bandwidth. Both benchmarks have two goals: (a) to get a detailed insight into the Performance strengths and weaknesses of different parallel communication and I/O patterns, and based on this, (b) to obtain a single bandwidth number that characterizes the average performance of the system namely communication and 1/0 bandwidth. Both benchmarks use a time driven approach and loop over a variety of communication and access patterns to characterize a system in an automated fashion. Results of the two benchmarks are given for several systems including IBM SPs, Cray T3E, NEC SX-5, and Hitachi SR 8000. After a redesign of b{_}eff{_}io, I/O bandwidth results for several compute partition sizes are achieved in an appropriate time for rapid benchmarking.

    For worldwide, a satellite communication network is an integral component of the global networking infrastructure. In this paper, we focus on developing effective routing techniques that consider both user preferences and network dynamic conditions. In particular, we develop a weighted-based route selection scheme for the core satellite communication network. Unlike the shortest path routing scheme, our scheme chooses the route from multiple matched entries based on the assigned weights that reflect the dynamic condition of networks. We also discuss how to derive the optimal weights for route assignment. To further meet user's preference, we implement the multiple path routing scheme to achieve the high rate of data transmission and the preemption based routing scheme to guarantee the data transmission for high priority users. Through extensive simulation studies, our data validates the effectiveness of our proposed routing schemes.

    The degradation of the performance of digital communication systems because of ionospheric scintillation effects can be reduced either by diversity techniques or by coding. The effectiveness of traditional space-diversity, frequency-diversity and time-diversity techniques is reviewed and design considerations isolated. Time-diversity signaling is then treated as an extremely simple form of coding. More advanced coding methods, such as diffuse threshold decoding and burst-trapping decoding, which appear attractive in combatting scintillation effects are discussed and design considerations noted. Finally, adaptive coding techniques appropriate when the general state of the channel is known are discussed.

  5. How to predict the potential effectiveness of communication materials.

    The Traveling Experiment (Travelex) is a new communications research method which enables researchers to predict relative effectiveness of communication materials in multilingual, agricultural, rural and personalistic societies. The measuring instrument used is the questionnaire, which can be converted into an interview if the subjects are nonliterate. Field researchers ask subjects either to evaluate instructional materials or to take brief tests in which the materials must be used to find the answers. Research findings indicate that the most effective publication format for attracting rural readers is the comic book with a brightly colored cover. Inside pages, however, have been shown to more effectively deliver instructional messages when they are in black and white. Realistic illustrations are preferred, as are opening sentences relating to the common experience of the target audience. The issues and implications for population control include the following: 1) a 2-sided presentation is most effective--a leaflet on the pill presenting both advantages and disadvantages of the contraceptive is most effective in correcting misconceptions among actual acceptors and, 2) the health appeal is more effective than the economic or status appeal, particularly for gaining acceptance of the IUD. When broadcast or film materials are used it is found that objective and interpretive reports are equally effective in increasing knowledge of family planning of various audiences. The broadcast version of the economic appeal seems to be effective in generating favorable attitudes toward the pill. PMID:12262256

    Provenance tools can help capture and represent the history of analytic processes. In addition to supporting analytic performance, provenance tools can be used to support memory of the process and communication of the steps to others. Objective evaluation methods are needed to evaluate how well provenance tools support analyst s memory and communication of analytic processes. In this paper, we present several methods for the evaluation of process memory, and we discuss the advantages and limitations of each. We discuss methods for determining a baseline process for comparison, and we describe various methods that can be used to elicit process recall, step ordering, and time estimations. Additionally, we discuss methods for conducting quantitative and qualitative analyses of process memory. By organizing possible memory evaluation methods and providing a meta-analysis of the potential benefits and drawbacks of different approaches, this paper can inform study design and encourage objective evaluation of process memory and communication.

    The current overriding thought in HIV/AIDS communication in developing countries is the need for a shift from the cognitive model, which emphasises the decision-making of the individual, to the activity model, which emphasises the context of the individual. In spite of the acknowledged media shift from the cognitive to the activity model in some developing countries, some HIV/AIDS communication scholars have felt otherwise. It was against this background that this study examined the content of some selected Nigerian newspapers to ascertain the attention paid to HIV/AIDS cognitive and activity information. Generally, the study found that Nigerian newspapers had shifted from the cognitive to the activity model of communication in their coverage of HIV/AIDS issues. The findings of the study seem inconsistent with the theoretical argument of some scholars that insufficient attention has been paid by mass media in developing countries to the activity model of HIV/AIDS communication. It is suggested that future research replicate the study for Nigerian and other developing countries’ mass media. PMID:23394854

    One of the key challenges facing the global war on terrorism (GWOT) and urban operations is the increased need for rapid and diverse information from distributed sources. For users to get adequate information on target types and movements, they would need reliable data. In order to facilitate reliable computational intelligence, we seek to explore the communication modulation tradeoffs affecting information distribution and accumulation. In this analysis, we explore the modulation techniques of Orthogonal Frequency Division Multiplexing (OFDM), Direct Sequence Spread Spectrum (DSSS), and statistical time-division multiple access (TDMA) as a function of the bit error rate and jitter that affect targeting performance. In the analysis, we simulate a Link 16 with a simple bandpass frequency shift keying (PSK) technique using different Signal-to-Noise ratios. The communications transfer delay and accuracy tradeoffs are assessed as to the effects incurred in targeting performance.

    Vaccine refusal rates have increased in recent years, highlighting the need for effective risk communication, especially over social media. Fuzzy-trace theory predicts that individuals encode bottom-line meaning ("gist") and statistical information ("verbatim") in parallel and those articles expressing a clear gist will be most compelling. We coded news articles (n=4581) collected during the 2014-2015 Disneyland measles for content including statistics, stories, or bottom-line gists regarding vaccines and vaccine-preventable illnesses. We measured the extent to which articles were compelling by how frequently they were shared on Facebook. The most widely shared articles expressed bottom-line gists, although articles containing statistics were also more likely to be shared than articles lacking statistics. Stories had limited impact on Facebook shares. Results support Fuzzy Trace Theory's predictions regarding the distinct yet parallel impact of categorical gist and statistical verbatim information on public health communication. PMID:27179915

    The SPACER server provides an interactive framework for exploring allosteric communication in proteins with different sizes, degrees of oligomerization and function. SPACER uses recently developed theoretical concepts based on the thermodynamic view of allostery. It proposes easily tractable and meaningful measures that allow users to analyze the effect of ligand binding on the intrinsic protein dynamics. The server shows potential allosteric sites and allows users to explore communication between the regulatory and functional sites. It is possible to explore, for instance, potential effector binding sites in a given structure as targets for allosteric drugs. As input, the server only requires a single structure. The server is freely available at http://allostery.bii.a-star.edu.sg/. PMID:23737445

    Effective Ways to Communicate Research Using the Poster Format Numerous academic conferences feature multiple venues for presentation of academic research results. While numerous associations provide conference presenters with potential best practices for the generation and presentation of information, not all presenters follow the suggested guidelines. This study reports the results of a random sample of poster presentations from an international conference spanning five days. More than 100 poster presentations where photographed to allow for manipulation and inspection of content that was content analyzed for key variables related to readability and usability. The results support that less content is best as well as effective use of color, font style and size.

    This paper provides a comparative analysis of modes of dialogue, non-verbal communication and embodied action relating to sex and health in two contrasting countries-India and South Africa-which have the world's two most heavily HIV-affected populations (in terms of numbers of people living with HIV). Drawing on material derived from multiple studies, including ethnographic and other forms of qualitative and multi-disciplinary research, the paper identifies commonalities as well as differences in communication relating to sex and sexual health in these diverse settings. The paper considers: first, how and by whom sex is and is not talked about, in public discourse and private conversation; second, how sexual intention and desire are communicated through indirect, non-verbal means in everyday life; and third, how references to sexuality and the sexual body re-enter within a more explicit set of indigenous discourses about health (rather than 'sexual health' per se), such as semen loss in India and womb 'dirtiness' in South Africa. The concluding section reflects on the implications of a comparative analysis such as this for current policy emphases on the importance of promoting verbal communication skills as part of 'life skills' for HIV prevention.

    This report describes a 63-year-old woman with Parkinson's disease showing loss of intelligibility of speech and severely impaired handwriting, despite undergoing physical and speech therapies. As the patient had sufficient residual motor abilities and adequate cognitive function and motivation, a computer-based communication aid with a software program for word prediction and voice output was tested, and was prescribed after a training period. One year later, the patient was still using the customized device to communicate and for leisure time, showing a high degree of satisfaction with the aid (assessed by QUEST 2.0), which had a positive impact on her well-being and quality of life (assessed by Psychosocial Impact of Assistive Devices Scales). In conclusion, in selected patients with Parkinson's disease, high-tech augmentative and alternative communication devices may be considered, tested, and prescribed after a positive training period. Follow-ups are necessary to monitor the effectiveness of the assistive device and respond to specific patient needs that may arise with using the device. PMID:22186614

    2014-12-01

    Climate researchers face regular scrutiny of their work from groups outside academia. In recent years, interest groups that oppose climate policy have targeted scientists with hate-mail campaigns, invasive document requests, hostile questioning and legal threats. In their day-to-day work, scientists struggle to respond to heated discussions about their research, whether from online commentators, opinion columnists, or special interest groups. Based on decades of experience and interviews with scientists, the Union of Concerned Scientists has developed a guide for communicating science amid heightened scrutiny. Building on the information contained in the UCS guide, this presentation will discuss best practices for climate researchers, including suggestions for when scrutiny can be ignored or when it deserves a response and methods for responding that can uphold scientific integrity while also protecting an individual researcher's reputation and ability to publicly communicate. Examples include scientists who have responded to bloggers criticizing their research, advocacy groups demanding their personal emails and policymakers targeting them with personal attacks. In understanding how to respond to scrutiny, scientists can bolster their own ability to communicate and curtail the chilling effect that scrutiny can have on other scientists conducting public enegagement.

    2015-01-01

    Background Communication failures between physicians and nurses are one of the most common causes of adverse events for hospitalized patients, as well as a major root cause of all sentinel events. Communication technology (ie, the electronic medical record, computerized provider order entry, email, and pagers), which is a component of health information technology (HIT), may help reduce some communication failures but increase others because of an inadequate understanding of how communication technology is used. Increasing use of health information and communication technologies is likely to affect communication between nurses and physicians. Objective The purpose of this study is to describe, in detail, how health information and communication technologies facilitate or hinder communication between nurses and physicians with the ultimate goal of identifying how we can optimize the use of these technologies to support effective communication. Effective communication is the process of developing shared understanding between communicators by establishing, testing, and maintaining relationships. Our theoretical model, based in communication and sociology theories, describes how health information and communication technologies affect communication through communication practices (ie, use of rich media; the location and availability of computers) and work relationships (ie, hierarchies and team stability). Therefore we seek to (1) identify the range of health information and communication technologies used in a national sample of medical-surgical acute care units, (2) describe communication practices and work relationships that may be influenced by health information and communication technologies in these same settings, and (3) explore how differences in health information and communication technologies, communication practices, and work relationships between physicians and nurses influence communication. Methods This 4-year study uses a sequential mixed

  1. Effect of the vegetarian diet on non-communicable diseases.

    A vegetarian diet generally includes plenty of vegetables and fruits, which are rich in phytochemicals, antioxidants, fiber, magnesium, vitamins C and E, Fe³⁺, folic acid and n-6 polyunsaturated fatty acid (PUFA), and is low in cholesterol, total fat and saturated fatty acid, sodium, Fe²⁺, zinc, vitamin A, B₁₂ and D, and especially n-3 PUFA. Mortality from all-cause, ischemic heart disease, and circulatory and cerebrovascular diseases was significantly lower in vegetarians than in omnivorous populations. Compared with omnivores, the incidence of cancer and type 2 diabetes was also significantly lower in vegetarians. However, vegetarians have a number of increased risk factors for non-communicable diseases such as increased plasma homocysteine, mean platelet volume and platelet aggregability compared with omnivores, which are associated with low intake of vitamin B₁₂ and n-3 PUFA. Based on the present data, it would seem appropriate for vegetarians to carefully design their diet, specifically focusing on increasing their intake of vitamin B₁₂ and n-3 PUFA to further reduce already low mortality and morbidity from non-communicable diseases.

    Household waste management has become essential in industrialized countries. For the recycling programs to be a success, all citizens must comply with the developed residential procedures. Governmental bodies are thus dependent on as many people as possible adhering to the sorting systems they develop. Since the 1970s oil crisis, governments have called upon social psychologists to help develop effective communication strategies. These studies have been based on persuasion and behavioral commitment (Kiesler, 1971). Less common are studies based on developing participative communication (Horsley, 1977), a form of communication that relies on individuals to pass on information. After going through the main communication perspectives as they relate to the sorting of household waste, a comparative field study will be presented on the effectiveness of persuasive, committing and participative communication. Participative communication relied on users to pass along information to their neighbors. The results show that the participants who spread information in this way, along with those who made a commitment, changed their behavior to a greater degree than the other participants.

    This experimental study examined differences in doctor-patient relationships according to the health communication strategies during cases of medical malpractices occurred at primary medical institution. A total of 116 subjects aged in their 20s-50s was sampled. The first medical malpractice scenario chosen was the medical malpractice case most frequently registered at the Korean Medical Association Mutual Aid and the second scenario was associated with materials and devices as the cause of malpractice. Four types of crisis communication strategy messages were utilized, consisting of denial, denial + ingratiation, apology, and apology + ingratiation. Subjects were classified into four research groups by crisis communication strategy to measure levels of trust, control mutuality, commitment, and satisfaction, before and after the occurrence of medical malpractice and application of communication strategies. The findings of this study revealed that the apology strategy, compared with the denial strategy, showed a smaller difference before and after the application of communication strategies in all variables of trust (F = 8.080, F = 5.768), control mutuality (F = 8.824, F = 9.081), commitment (F = 9.815, F = 8.301), and satisfaction (F = 8.723, F = 5.638). Further, a significant interaction effect was shown between variables. The apology strategy, compared with the denial strategy, was effective in the improvement of doctor-patient relationships in both Scenarios I and II. For Scenario I, the apology strategy without ingratiation boosted commitment and satisfaction, but for Scenario II, utilizing the apology strategy with ingratiation boosted the effectiveness of trust and commitment.

    Intra-operative transesophageal echocardiography (TEE) is a mature imaging technique which represents the premier surgical quality control instrument in the contemporary operating room. In adult cardiac surgery, management of valvular heart disease and related structural cardiac abnormalities derive the most benefit from perioperative echocardiography which includes pre-operative transthoracic echocardiography, intra-operative TEE and post-surgical echocardiographic surveillance. This review discusses the theoretical background upon which these imaging techniques are built-on, and offers a practical state-of-the-art guide on their application, emphasizing the importance of anatomic relationships, mechanisms of dysfunction and effective communication with our surgeons.

    Digital data scrambling has been considered for communication systems using NRZ symbol formats. The purpose is to increase the number of transitions in the data to improve the performance of the symbol synchronizer. This is accomplished without expanding the bandwidth but at the expense of increasing the data bit error rate (BER). Models for the scramblers/descramblers of practical interest are presented together with the appropriate link model. The effects of scrambling on the performance of coded and uncoded links are studied. The results are illustrated by application to the Tracking and Data Relay Satellite System (TDRSS) links. Conclusions regarding the usefulness of scrambling are also given.

    1995-01-01

    The atmosphere has a significant impact on the design of a global communication system operating at 20 GHz. The system under consideration has a total atmospheric link attenuation budget that is less than 6 dB. For this relatively small link margin, rain, cloud, and molecular attenuation have to be taken into account. For an assessment of system performance on a global basis, attenuation models are utilized. There is concern whether current models can adequately describe the atmospheric effects such that a system planner can properly allocate his resources for superior overall system performance. The atmospheric attenuation as predicted by models will be examined.

    This study investigated the effect of variation in partner-initiated pause time on the expressive communication of young people who use Augmentative and Alternative Communication (AAC). Eight participants aged 8;11-20;08 years (mean 16;02 years) participated in the study. Three pause time conditions (2, 10, and 45 seconds) were trialled during a scripted shared storybook reading task. A total of 27 turn opportunities were provided for participants during the task. Participant interactions were analysed for the percentage of responses made to a turn opportunity, mean length of utterance in words (MLU), percentage of assertive conversational acts made, and the modes of communication used. Findings indicated that participants were more likely to respond to a turn opportunity when their communication partner provided a longer pause time. Additionally, a longer pause time resulted in longer MLUs. Participants did not use more assertive conversational acts and continued to use a variety of communication modes when provided with a longer pause time. Results indicate that increasing pause time is an effective strategy to support the development of expressive communication for young people who use AAC. This suggests the need for professionals providing AAC services to encourage communication partners to provide extended pauses during interactions. PMID:21888558

    This article examines the effects of nonviolent communication (NVC) training on the interprofessional collaboration (IPC) of two health and social services sector care teams. The study was conducted in 2013 with two interprofessional teams (N = 9) using a mixed method research design to measure the effects of the training. Individual IPC competency was measured using the Team Observed Structured Clinical Encounter tool, and group competency using the Observed Interprofessional Collaboration tool. A focus group was held to collect participant perceptions of what they learned in the training. Results revealed improvements in individual competency in client/family-centered collaboration and role clarification. Improvements in group competency were also found with respect to teams' ability to develop a shared plan of action. Data suggests that participants accepted and adopted training content. After the training, they appeared better able to identify the effects of spontaneous communication, more understanding of the mechanisms of empathy, and in a better position to foster collective leadership.

    Clinical trial (CT) participation is low among African Americans (AAs). To better communicate with AAs about the importance of CTs, the purpose of this study was to explore the communication sources and perceived effective communication channels and strategies through which the general public, AAs, and White individuals receive CT information. A quantitative telephone survey was conducted with AAs and Whites in one Southern state (N = 511). The measures assessed CT sources of information, perceived effectiveness of communication channels and strategies, CT understanding, and CT participation. Descriptive and bivariate analyses were used to compare responses overall and by race. AAs reported being exposed to more CT information than Whites. AAs received CT information most often through television, social media, and doctors compared to Whites. Perceived effectiveness of communication strategies and channels varied by race. AAs preferred simple and easy-to-understand CT information distributed through faith-based organizations. Whites preferred to receive CT information through a trustworthy source (e.g., doctor). There were no significant differences between AAs and Whites in their perceived effectiveness of media sources (e.g., Internet). Recommendations are provided to help health promotion practitioners and CT recruiters tailor information and communicate it effectively to potential AA and White CT participants. PMID:26715695

    There is emerging evidence to demonstrate the efficacy of music-based interventions for improving social functioning in children with Autism Spectrum Disorders (ASD). While this evidence lends some support in favor of using song over spoken directives in facilitating engagement and receptive intervention in ASD, there has been little research that has investigated the efficacy of such stimuli on socio-communicative responsiveness measures. Here, we present preliminary results from a pilot study which tested whether sung instruction, as compared to spoken directives, could elicit greater number of socio-communicative behaviors in young children with ASD. Using an adapted single-subject design, three children between the ages of 3 and 4 years, participated in a programme consisting of 18 sessions, of which 9 were delivered with spoken directives and 9 with sung. Sessions were counterbalanced and randomized for three play activities-block matching, picture matching and clay play. All sessions were video-recorded for post-hoc observational coding of three behavioral metrics which included performance, frequency of social gesture and eye contact. Analysis of the videos by two independent raters indicated increased socio-communicative responsiveness in terms of frequency of social gesture as well as eye contact during sung compared to spoken conditions, across all participants. Our findings suggest that sung directives may play a useful role in engaging children with ASD and also serve as an effective interventional medium to enhance socio-communicative responsiveness.

    This brief report examined teenagers’ sexuality communication with their parents and extended families. It compared who teens of early parents (those who had children when they were adolescents) and teens of later parents (those who were adults when they had children) talk to about sex. Eighth grade students (N=1281) in 24 schools completed survey items about their communication about sex. Structural equation modeling was used to predict communication profiles, while adjusting for the nesting of students within schools. After controlling for teens’ age, gender, race/ethnicity, grades, parent/guardian closeness, and social desirability of survey responses, as well as family status and median family income, results showed that teens of early (teen) parents were more likely than teens of later (adult) parents to talk with both parents and extended family about sex and less likely than later parents to talk only with parents. These findings indicate that realities of teen sexuality communication for teens of early parents may extend beyond a parent-teen model to include extended family. Extended family involvement in educational outreach is a potential untapped resource to support sexual health for teens of early parents. PMID:27499816

    Using data from the 4-H Study of Positive Youth Development, a longitudinal study involving U.S. adolescents, multi-group structural equation modeling (SEM) was used to evaluate whether news media use is predictive of a set of civic indicators (civic duty, civic efficacy, neighborhood social connection, and civic participation) for youth in Grades 8, 9, and 10, via an indirect effect of interpersonal communication about politics with parents. The proposed model had a good fit within each grade. News media use was predictive of interpersonal communication with parents and in turn, interpersonal communication was predictive of civic duty, civic efficacy, neighborhood social connection, and civic participation. The cross-group comparison of the structural model suggests that the predictive qualities of news media use and interpersonal communication are comparable across grades. The role of media use and interpersonal communication in fostering civic development and socialization as well as implications for future research are discussed. PMID:22118509

    The effects of unwanted external optical feedback on synchronized chaotic optical communication systems are studied numerically. We consider an open-loop configuration consisting of a transmitter laser with double external optical feedbacks and a receiver laser with optical injection from the transmitter laser. First, including the effects of unwanted optical feedback, the synchronization performances of both the complete synchronization and the generalized synchronization are examined. Then the encoding and decoding performances of the generalized synchronization and the effects of the introduced feedback are investigated, respectively. Finally, we study the control of the unwanted feedback on the dynamics of the transmitter laser and briefly discuss the system security when the transmitter laser is driven to operate in a steady state or periodic oscillation state by the additional feedback.

  17. Designing Effective Persuasive Systems Utilizing the Power of Entanglement: Communication Channel, Strategy and Affect

    With rapid advances in information and communication technology, computer-mediated communication (CMC) technologies are utilizing multiple IT platforms such as email, websites, cell-phones/PDAs, social networking sites, and gaming environments. However, no studies have compared the effectiveness of a persuasive system using such alternative channels and various persuasive techniques. Moreover, how affective computing impacts the effectiveness of persuasive systems is not clear. This study proposes (1) persuasive technology channels in combination with persuasive strategies will have different persuasive effectiveness; (2) Adding positive emotion to a message that leads to a better overall user experience could increase persuasive effectiveness. The affective computing or emotion information was added to the experiment using emoticons. The initial results of a pilot study show that computer-mediated communication channels along with various persuasive strategies can affect the persuasive effectiveness to varying degrees. These results also shows that adding a positive emoticon to a message leads to a better user experience which increases the overall persuasive effectiveness of a system.

    Deep space telemetry is and will remain signal-to-noise limited and vulnerable to interference. A need exists to increase received signal power and decrease noise. This includes going to Ka-band in the mid-1990's to increase directivity. The effects of a wet atmosphere can increase the noise temperature by a factor of 5 or more, even at X-band, but the order of magnitude increase in average data rate obtainable at Ka-band relative to X-band makes the increased uncertainty a good trade. Lowbit error probabilities required by data compression are available both theoretically and practically with coding, at an infinitesimal power penalty rather than the 10 to 15 dB more power required to reduce error probabilities without coding. Advances are coming rapidly in coding, as with the new constraint-length 15 rate 1/4 convolutional code concatenated with the already existing Reed-Solomon code to be demonstrated on Galileo. In addition, high density spacecraft data storage will allow selective retransmissions, even from the edge of the Solar System, to overcome weather effects. In general, deep space communication was able to operate, and will continue to operate, closer to theoretical limits than any other form of communication. These include limits in antenna area and directivity, system noise temperature, coding efficiency, and everything else. The deep space communication links of the mid-90's and beyond will be compatible with new instruments and compression algorithms and represent a sensible investment in an overall end-to-end information system design.

    This report reviews the success rates and complications of native tissue (nonmesh) vaginal reconstruction of pelvic organ prolapse by compartment. For apical prolapse, both uterosacral ligament suspensions and sacrospinous ligament fixations are effective and provided similar outcomes in anatomy and function with few adverse events. In the anterior compartment, traditional colporrhaphy technique is no different than ultralateral suturing. In the posterior compartment, transvaginal rectocele repair is superior to transanal repair. For uterine preservation, sacrospinous hysteropexy is not inferior to vaginal hysterectomy with uterosacral ligament suspension for treatment of apical uterovaginal prolapse. PMID:26880509

  2. Using the Psychology of Language to Effectively Communicate Actionable Science

    The words used to articulate science can have as significant a psychological impact on public perception as the data itself. It is therefore essential to utilize language that not only accurately relates the scientific information, but also effectively conveys a message that is congruent with the presenter's motivation for expressing the data. This is especially relevant for environmental subjects that are surrounded by emotionally charged, political discourses. For example are terms like catastrophe and disaster; while these words may accurately illustrate impartial scientific data, they will likely trigger psychological responses in audiences such as fear or denial that have a detrimental impact on the human decision making process. I propose a set of 5 key principles to assist in communicating data to the general public that both support the transfer of ideas and the presenter's intended psychological impact. 1) Articulate the underlying intentions that motivate the communication of data in a transparent manner 2) Use language congruent with the presenter's stated intentions 3) Maintain a neutral, non-judgmental attitude towards the complex human psychological and emotional dynamics present in a target audience 4) Demonstrate acceptance and compassion when analyzing past and present human actions that adversely affect the environment 5) Develop a perspective of non-attachment when proposing future actions and/or consequences of current human behaviors. The application of these 5 principles provides a framework to move from our current understanding of problems and solutions to effective physical action that allows us to gracefully adapt with our ever changing planet.

    Hazard maps are considered essential tools in the communication of volcanic risk between scientists, the local authorities and the public. This study investigates the efficacy of such maps for the volcanic island of Montserrat in the West Indies using both quantitative and qualitative research techniques. Normal plan view maps, which have been used on the island over the last 10 years of the crisis, are evaluated against specially produced three-dimensional (3D) maps and perspective photographs. Thirty-two demographically representative respondents of mixed backgrounds, sex, education and location were interviewed and asked to complete a range of tasks and identification on the maps and photographs. The overall results show that ordinary people have problems interpreting their environment as a mapped representation. We found respondents’ ability to locate and orientate themselves as well as convey information relating to volcanic hazards was improved when using aerial photographs rather than traditional plan view contour maps. There was a slight improvement in the use of the 3D maps, especially in terms of topographic recognition. However, the most striking increase in effectiveness was found with the perspective photographs, which enabled people to identify features and their orientation much more readily. For Montserrat it appears that well labelled aerial and perspective photographs are the most effective geo-spatial method of communicating volcanic risks.

  4. Comparing Open and Guided Inquiry Activities in an Informal Physics Program To Promote Agency, Communication, and Reasoning

    In this thesis, we investigate an informal after-school science program. We examine two inquiry curricula used in this program; one more guided and the other more open. We have developed new methods to analyze middle school children's scientific notebooks, and we measure how the children exhibit agency, how the children communicate, and the mechanistic reasoning children use. We compare the two curricula and find that the children exhibit more agency in the open curriculum, write and draw more in the open curriculum, demonstrate a wide variety of scientific communication, and use more varied types of mechanistic reasoning in the open curriculum. These aspects can be linked to science identity, and we conclude that the more open curriculum supports the development of positive science identity.

    This article investigates how to more effectively conduct risk communication to increase the probability of successful control of an epidemic in Taiwan. The epidemic control of H1N1 in Taiwan in 2010 was studied. We used factor analysis and Decision-Making Trial and Evaluation Laboratory (DEMATEL) to obtain the total influence for each factor and to determine the critical factors among them. After being processed using proposed operational procedures, we obtained the critical factors and found that the government plays the key role in successful epidemic control. To reduce the resistance to efforts that seek to prevent pandemic crises, some necessary intervention activities, such as fairly and honorably exploring the complete relevant information and revealing the side effects of vaccines in a manner that is easily understood, were recommended. These could lead to an increase in immunizations among Taiwanese people by gaining their trust and commitment, thus achieving control of this epidemic. PMID:23239748

    Communication skills deficits and stereotyped behaviors are frequently found among people with pervasive developmental disabilities like autism. These communication and behavioral oddities of autism are often considered to be difficult to treat and are challenging. Picture exchange communication system (PECS) is a six-phase picture system based on applied behavior analysis and is specially designed to overcome these communication difficulties in children with autism by encouraging the child to be the communication initiator. The present paper throws light on the process of using PECS along with other traditional behavioral approaches in managing communication deficits and behavioral stereotypies in a seven-year-old male child diagnosed as having childhood autism. The identified target behaviors of repeated head turning, flapping his hands, poor communication skills were assessed using various rating scales including visual analogue scale as per clinician observation and parental reports and managed using PECS as an adjunct to traditional behavioral techniques of contingency management, differential reinforcement, task direction and reprimand. Outcome was assessed using same tools after thirty-two sessions of interventions spread over three months. Significant improvements of around 60% were observed in the target behaviors. PMID:21716776
