    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.

    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

    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

    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.

    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.

    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.

    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.

    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

    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.

  3. Commentary: Will academia embrace comparative effectiveness research?

    PubMed

    Lauer, Michael S

    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.

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

    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

    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. PMID:26646861

    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.

    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.

    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.

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.

    2013-01-01

    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

  19. Effectively Responding to Public Scrutiny When Communicating Climate Science.

    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.

    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.

    1985-01-01

    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.

    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

    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

    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.

    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

    NASA Astrophysics Data System (ADS)

    Li, Haiqing; Chatterjee, Samir

    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.

  18. Deep space communications, weather effects, and error control

    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

    2007-11-01

    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.

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

    NASA Astrophysics Data System (ADS)

    Hall, J. M.

    2014-12-01

    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.

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

    Wulf, Rosemary Philomena

    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

    1997-01-01

    This paper presents part of a survey which investigated people's response to different approaches to health education campaigns. The main objective of the original study was to find out whether the respondents preferred a fear-inducing campaign or a positive image advertising. Two anti-smoking advertisement produced by the Health Education Board for Scotland (HEBS), one using a fear appeal and the other, using a positive image were examined. A sample of 394 subjects in three age groups took part in the study and they were interviewed by means of a questionnaire. A high proportion in each group, including smokers indicated that they preferred the fear-inducing campaign. To investigate why people prefer this type of image, respondents were asked to explain their reasons. It was found that effective communication requires: (1) reality, (2) clear cut message, (3) simplicity, and (4) thought provoking nature and impact of the message. In addition, with regard to the advertising appeals it was found that both positive image and negative image campaigns could be used to attract attention and consequently communicate with the target population. Finally, the findings of this study in the light of psychosocial theories are discussed, and the Preference Model is proposed as providing a better understanding of the process behind people's preferences.

    2015-10-01

    The current Ebola virus outbreak has highlighted the uncertainties surrounding many aspects of Ebola virus virology, including routes of transmission. The scientific community played a leading role during the outbreak-potentially, the largest of its kind-as many of the questions surrounding ebolaviruses have only been interrogated in the laboratory. Scientists provided an invaluable resource for clinicians, public health officials, policy makers, and the lay public in understanding the progress of Ebola virus disease and the continuing outbreak. Not all of the scientific communication, however, was accurate or effective. There were multiple instances of published articles during the height of the outbreak containing potentially misleading scientific language that spurred media overreaction and potentially jeopardized preparedness and policy decisions at critical points. Here, we use articles declaring the potential for airborne transmission of Ebola virus as a case study in the inaccurate reporting of basic science, and we provide recommendations for improving the communication about unknown aspects of disease during public health crises.

    Individuals with autism spectrum disorders (ASDs) have difficulty communicating in ways that are primarily for initiating and maintaining social relatedness (i.e., social communication). We hypothesized that the way researchers measured social communication would affect whether treatment effects were found. Using a best evidence review method, we found that treatments were shown to improve social communication outcomes approximately 54% of the time. The probability that a treatment affected social communication varied greatly depending on whether social communication was directly targeted (63%) or not (39%). Finally, the probability that a treatment affected social communication also varied greatly depending on whether social communication as measured in (a) contexts very similar to treatment sessions (82%) or (b) contexts that differed from treatment on at least setting, materials, and communication partner (33%). This paper also provides several methodological contributions. PMID:25346776

    2016-06-01

    This study examines the effect of communication strategy instruction on EFL students' oral communicative ability and their strategic competence. In a 14-week English as a Foreign Language (EFL) course (English Use II) based on Communicative Language Teaching approach, 80 learners were divided into two groups. The strategy training group ([Formula: see text]) received CS training based on a training program designed for the purpose of the present research, whereas the control group ([Formula: see text]) received only the normal communicative course using Click On 3, with no explicit focus on CSs. The communication strategies targeted in the training program included circumlocution (paraphrase), appeal for help, asking for repetition, clarification request, confirmation request, self-repair, and guessing. Pre- and post-test procedures were used to find out the effect of strategy training on language proficiency and CS use. The effect of the training was assessed by three types of data collection: the participants' pre- and post-IELTS speaking test scores, transcription data from the speaking IELTS test, and 'Click On' Exit Test scores. The findings revealed that participants in the strategy training group significantly outperformed the control group in their IELTS speaking test scores. The results of the post-test transcription data also confirmed that the participants in the strategy training group used more CSs, which could be attributed to the CS training program. The findings of the present research have implications for language teachers, and syllabus designers. PMID:25900534

    The ongoing drought in California is having a tremendous impact on the state economy and the daily lives of its citizens. The impact of the drought is also exacerbated by the complexity of water issues in California, and the lack of understanding in the general public about this complexity. Our project has two goals, both focused on the broader issue of increasing the public's understanding of water issues by helping scientists engage more effectively with the public. The first is to use a survey to assess the perceptions of California residents regarding the ongoing drought affecting the state. The first portion of our survey allows our participants to share, in a free response format, their understanding of the causes, consequences, and potential solutions to the problems caused by drought. This allowed us to get some insight into how people view the drought prior to being lead by our questions, and allows us to conduct a detailed linguistic analysis of the text they provide. Next we asked a battery of questions meant to assess our participants' views on issues such as their views of water rights, the commoditization of water, and what role the government (both state and local) should play in managing California's water. The second goal is to use this data to create profiles that can then be used to more effectively communicate with and educate the public. Together, the results will provide new and valuable insights into how views of drought vary across stakeholders, and could inform policies related to water use. The presentation will include discussion of these results, their implications for best practices by science communicators, and potential impact on policy.

    1981-01-01

    Several aspects of ward routine were changed to study the effects of environmental manipulation on the behavior of 21 psychogeriatric patients. Furniture was rearranged to be more conductive to conversation (i.e., grouped around tables instead of along corridor walls), and mealtime routines were changed to allow patients more time to eat, more freedom in choosing the composition of the meal, and more pleasant surroundings. Patients were divided into experimental and control groups, and data were collected on the frequency of verbal and tactile communication and degree of skill in eating behavior. Following baseline, environmental changes were introduced across behaviors. Results show that the frequency of communication increased for the experimental group, as compared to both baseline and the control group. Eating behavior also improved significantly for the experimental group. The study shows that minor changes in the physical environment can promote therapeutic change in the behavior of patients diagnosed as senile dementia. PMID:7216931

    The multibeam communications package (MCP) for the Advanced Communications Technology Satellite (ACTS) to be STS-launched by NASA in 1988 for experimental demonstration of satellite-switched TDMA (at 220 Mbit/sec) and baseband-processor signal routing (at 110 or 27.5 Mbit/sec) is characterized. The developmental history of the ACTS, the program definition, and the spacecraft-bus and MCP parameters are reviewed and illustrated with drawings, block diagrams, and maps of the coverage plan. Advanced features of the MPC include 4.5-dB-noise-figure 30-GHz FET amplifiers and 20-GHz TWTA transmitters which provide either 40-W or 8-W RF output, depending on rain conditions. The technologies being tested in ACTS can give frequency-reuse factors as high as 20, thus greatly expanding the orbit/spectrum resources available for U.S. communications use.

    Rowley, Jack T; Joyner, Ken H

    2012-01-01

    This paper presents analyses of data from surveys of radio base stations in 23 countries across five continents from the year 2000 onward and includes over 173,000 individual data points. The research compared the results of the national surveys, investigated chronological trends and compared exposures by technology. The key findings from this data are that irrespective of country, the year and cellular technology, exposures to radio signals at ground level were only a small fraction of the relevant human exposure standards. Importantly, there has been no significant increase in exposure levels since the widespread introduction of 3G mobile services, which should be reassuring for policy makers and negate the need for post-installation measurements at ground level for compliance purposes. There may be areas close to antennas where compliance levels could be exceeded. Future potential work includes extending the study to additional countries, development of cumulative exposure distributions and investigating the possibility of linking exposure measurements to population statistics to assess the distribution of exposure levels relative to population percentiles.

    Alberto, C S; Villanueva, C L

    1979-01-01

    Results of 2 workshops on the improvement of communication and motivational skills of outreach workers using research results and field experiences are presented. General strategies, illustrative cases, and specific IEC strategies geared to the solution of common problems are suggested. General strategies for identifying opportunities for introduction of population and family planning in the community include use of felt needs and problems of the community as vehicles for introduction, coordination with other agencies operating in the community, winning the support of influential and accepted leaders in the community, and establishing credibility with the people before launching population projects. Strategies for breaking through traditional values and beliefs include emphasizing aspects of the population program that do not run counter to religious beliefs, using messages which emphasize qualities highly valued by the people, being careful to respect persons the community looks up to regardless of their opposition, considering the cultural background and preparation of the audience before introducing sensitive subjects, and appealing to people's needs and interests to elicit participation. Rumors and misconceptions on family planning may be counteracted by directing motivational and informational efforts at persons likely to influence potential acceptors as well as the potential acceptors themselves, avoiding antagonizing religious leaders who preach against family planning, presenting only accurate family planning information, and establishing the source of rumors about side effects. Complaints about side effects should be attended promptly, clear and specific instructions on method use should be given, and the worker should present herself as a satisfied user. PMID:12233386

  16. Effective Use of Social Media in Communicating Climate Science

    The internet and social media have been a critical vector for misinformation on climate change. Scientists have not always been proactive or effective in utilizing the medium to bring attention to the best science, to correct misinformation and overcome urban myths. Similarly, mainstream journalists have been handicapped in dealing with the wide open nature of the medium, and often muted by editorial concerns or budget restrictions. Independent communicators who are highly motivated can make inroads in this area by using the internet's immediacy and connectivity to consistently connect viewers and readers to reliable information. Over the last 4 years, I have developed a series of you tube videos, made deliberately provocative to engage the internet's confrontational culture, but carefully crafted to bring the best science into the freewheeling community. In doing so, I have won the confidence of leading climate scientists, and in some cases assisted them in clarifying their message. This presentation will share simple tips, useful practices, and effective strategies for making complex material more clear and user friendly, and help scientists better convey the stories hidden in their data.

  17. Cooperative Electronic Mail: Effective Communication Technology for Introductory Chemistry

    Pence, Laura E.

    1999-05-01

    One drawback to using cooperative learning in the classroom is that it takes up class time and reduces the amount of content that can be covered during a semester. Cooperative electronic mail is an excellent alternate method of using cooperative learning that shifts the medium of interaction to the computer and encourages students to learn to communicate effectively through technology. In this project, three types of exercises were assigned, one prior to each exam. These three assignments were (i) an open-ended question, (ii) a traditional cooperative activity done electronically, and (iii) an exercise to allow students to write exam questions for each other. The average participation rate in the exercises was 90% over four semesters, which indicated that the project was an effective incentive to get students to use email regularly. The evaluations of the project were also extremely positive. One surprising result of the assessment was that female students gave even more favorable responses than men, suggesting that this project was an excellent way to encourage women to use computer technology.

    2005-01-01

    The practice of public relations has experienced tremendous growth and evolution over the past 25 years, especially in the area of medical public relations. The constant changes in health care delivery have often led to increased need for communication with important publics. At the same time, practitioners in all fields of public relations have explored methods of accurately measuring the effectiveness of public relations programs. One such method of evaluation is the communication audit. This paper includes a brief overview of the communication audit concept followed by a case study based on an audit conducted for a small, multicultural non-profit health-care agency. Steps taken to conduct the audit and the methodology used are discussed. An analysis of the data is used to address two research questions regarding the efficacy of the Center's mission and vision. Suggestions for future audits are provided. PMID:16521672

    The capability of effectively communicating is crucial when providing palliative care, especially when the patient is a child. Communication among healthcare professionals with the child and family members must be clear, concise, and consistent. Use of a communication tool provides documentation for conversations, treatment plans, and specific desires related to care. This paper describes communication theory, portrays the use of this theory to develop a communication tool, and illustrates the use of this tool by multidisciplinary members of a healthcare team to provide pediatric palliative care.

    Blevins, James K.; Coxworth, James E.; Herndon, James G.; Hawkes, Kristen

    2015-01-01

    Ovarian cycling continues to similar ages in women and chimpanzees yet our nearest living cousins become decrepit during their fertile years and rarely outlive them. Given the importance of estrogen in maintaining physiological systems aside from fertility, similar ovarian aging in humans and chimpanzees combined with somatic aging differences indicates an important role for nonovarian estrogen. Consistent with this framework, researchers have nominated the adrenal androgen dehydroepiandrosterone (DHEA) and its sulfate (DHEAS), which can be peripherally converted to estrogen, as a biomarker of aging in humans and other primates. Faster decline in production of this steroid with age in chimpanzees could help explain somatic aging differences. Here, we report circulating levels of DHEAS in captive female chimpanzees and compare them with published levels in women. Instead of faster, the decline is slower in chimpanzees, but from a much lower peak. Levels reported for other great apes are lower still. These results point away from slowed decline but toward increased DHEAS production as one of the mechanisms underlying the evolution of human longevity. PMID:23818143

  10. Does mood really influence comparative optimism? Tracking an elusive effect.

    PubMed

    Drace, Sasa; Desrichard, Olivier; Shepperd, James A; Hoorens, Vera

    2009-12-01

    Methodological limitations call into question prior evidence that positive moods are associated with greater comparative optimism. Experiments 1-4 tested if mood affects comparative optimism using a mood manipulation that minimized experimenter demand. While the procedure was successful in inducing mood, we found no evidence for a mood effect on comparative optimism. The absence of a mood effect was not due to participants correcting their judgments in response to a presumed mood bias (Experiments 2, 3 and 4) or to participants proactively regulating their mood (Experiments 3 and 4). Experiment 5 compared the mood manipulation of Experiments 1-4 with an autobiographical recall procedure. Although the two methods were equally effective in inducing mood, only autobiographical recall influenced participants' comparative optimism. Study 6 provides preliminary evidence that experimenter demand may be responsible for the effects of autobiographical recall on comparative judgments. PMID:19108749

    Segal, Leon D.

    1994-01-01

    The investigation looked at the effects of the spatial layout and functionality of cockpit displays and controls on crew communication. Specifically, the study focused on the intra-cockpit crew interaction, and subsequent task performance, of airline pilots flying different configurations of a new electronic checklist, designed and tested in a high-fidelity simulator at NASA Ames Research Center. The first part of this proposal establishes the theoretical background for the assumptions underlying the research, suggesting that in the context of the interaction between a multi-operator crew and a machine, the design and configuration of the interface will affect interactions between individual operators and the machine, and subsequently, the interaction between operators. In view of the latest trends in cockpit interface design and flight-deck technology, in particular, the centralization of displays and controls, the introduction identifies certain problems associated with these modern designs and suggests specific design issues to which the expected results could be applied. A detailed research program and methodology is outlined and the results are described and discussed. Overall, differences in cockpit design were shown to impact the activity within the cockpit, including interactions between pilots and aircraft and the cooperative interactions between pilots.

    Balakrishnan, B.; Woods, P. C.

    2013-05-01

    Over the years, rapid development in computer technology has engendered simulation-based laboratory (lab) in addition to the traditional hands-on (physical) lab. Many higher education institutions adopt simulation lab, replacing some existing physical lab experiments. The creation of new systems for conducting engineering lab activities has raised concerns among educators on the merits and shortcomings of both physical and simulation labs; at the same time, many arguments have been raised on the differences of both labs. Investigating the effectiveness of both labs is complicated, as there are multiple factors that should be considered. In view of this challenge, a study on students' perspectives on their experience related to key aspects on engineering laboratory exercise was conducted. In this study, the Visual Auditory Read and Kinetic model was utilised to measure the students' cognitive styles. The investigation was done through a survey among participants from Multimedia University, Malaysia. The findings revealed that there are significant differences for most of the aspects in physical and simulation labs.

  18. A spiritually based approach to breast cancer awareness: cognitive response analysis of communication effectiveness.

    PubMed

    Holt, Cheryl L; Lee, Crystal; Wright, Katrina

    2008-01-01

    The purpose of this study was to compare the communication effectiveness of a spiritually based approach to breast cancer early detection education with a secular approach, among African American women, by conducting a cognitive response analysis. A total of 108 women from 6 Alabama churches were randomly assigned by church to receive a spiritually based or secular educational booklet discussing breast cancer early detection. Based on the elaboration likelihood model (Petty & Cacioppo, 1981), after reading the booklets participants were asked to complete a thought-listing task, writing down any thoughts they experienced and rating them as positive, negative, or neutral. Two independent coders then used 5 dimensions to code participants' thoughts. Compared with the secular booklet, the spiritually based booklet resulted in significantly more thoughts involving personal connection, self-assessment, and spiritually based responses. These results suggest that a spiritually based approach to breast cancer awareness may be more effective than the secular approach because it caused women to more actively process the message, stimulating central route processing. The incorporation of spiritually based content into church-based breast cancer education could be a promising health communication approach for African American women. PMID:18443989

    2016-01-01

    Health communication interventions have been effective in promoting fruit and vegetable consumption (FVC). To explore mechanisms underlying health communication effectiveness, we investigated whether information processes mediated the relationship between health communication and FVC, using data from NC STRIDES. NC STRIDES tested the efficacy of two health communication strategies to promote FVC among a diverse population-based sample of older adults. Participants were randomized to one of four groups: control, tailored print communication (TPC), telephone motivational interviewing (TMI), or combined (TPC+TMI). Multi-sample structural equation models were constructed to analyze data from 469 participants. Information processes mediated the effect of TMI and TPC+TMI on FVC. TMI had an indirect effect on FVC through relevance of the communications. TPC+TMI influenced FVC through perceived relevance of the communications, trust in the communications, and dose recall via two paths. In the first path, relevance was associated with trust. Trust was associated with recall, and greater recall predicted FVC. In the second path, relevance was associated with dose recall, and more recall predicted FVC. Thus, we found that key information processes mediated the relationship between a health communication intervention and FVC. Further research should investigate ways to enhance relevance, trust, and recall during the delivery of interventions. PMID:21132593

    2009-08-01

    Using a sample (N = 453) drawn from a representative sampling frame of couples who are married or living together and have a 3 to 7 year-old child, this study investigates (a) the amount and specific areas of change desired by men and women, (b) the relation between relationship adjustment and desired change; and (c) the ways in which partners negotiate change. On the Areas of Change Questionnaire, women compared with men, wanted greater increases in their partners' emotional and companionate behaviors, instrumental support, and parenting involvement; men wanted greater increases in sex. Using the Actor-Partner Interdependence Model (Kenny, 1996), both men's and women's relationship adjustment predicted desired change (i.e., actor effects), over and above the effects of their partners' adjustment (i.e., partner effects); partner effects were not significant. Each couple was also observed discussing the man's and the woman's top desired change area. Both men and women behaved more positively during the partner-initiated conversations than during their own-initiated conversations. Women, compared with men, were more negative in their own and in their partners' conversations. PMID:19685983

    PubMed

    Liu, Wei; Manias, Elizabeth; Gerdtz, Marie

    2014-03-01

    Physical environments of clinical settings play an important role in health communication processes. Effective medication management requires seamless communication among health professionals of different disciplines. This paper explores how physical environments affect communication processes for managing medications and patient safety in acute care hospital settings. Findings highlighted the impact of environmental interruptions on communication processes about medications. In response to frequent interruptions and limited space within working environments, nurses, doctors and pharmacists developed adaptive practices in the local clinical context. Communication difficulties were associated with the ward physical layout, the controlled drug key and the medication retrieving device. Health professionals should be provided with opportunities to discuss the effects of ward environments on medication communication processes and how this impacts medication safety. Hospital administrators and architects need to consider health professionals' views and experiences when designing hospital spaces. PMID:24486620

  2. Numerical simulation of the effect of dissipation and phase fluctuation in a direct communication scheme

    NASA Astrophysics Data System (ADS)

    Li, Fu; Zhang, Jun-Xiang; Zhu, Shi-Yao

    2015-06-01

    Recently, the direct counterfactual communication protocol, proposed by Salih et al (2013 Phys. Rev. Lett. 110 170502) using a single photon source under ideal conditions (no dissipation, no phase fluctuation and an infinite number of beam splitters), has attracted much interest from a broad range of scientists. In order to put the direct communication protocol into a realistic framework, we numerically simulate the effect of the dissipation and the phase fluctuation with a finite number of beam splitters. Our calculation shows that the dissipation and phase fluctuation will dramatically decrease the reliability and the efficiency of communication, and even corrupt the communication. To counteract the negative effect of dissipation, we propose the balanced dissipation method, which substantially improves the reliability of the protocol at the expense of decreasing communication efficiency. Meanwhile, our theoretical derivation shows that the reliability and efficiency of communication are independent of the input state: a single photon state or a coherent state.

  3. Placebo Effects and the Ethics of Therapeutic Communication: A Pragmatic Perspective.

    PubMed

    Annoni, Marco; Miller, Franklin G

    2016-03-01

    In this article we explore the ethics of manipulating verbal information for the sake of influencing health outcomes through placebo and nocebo responses. Recent scientific research on placebo and nocebo effects has drawn attention to the ways in which communication by health professionals may modulate the symptoms of patients across an array of highly prevalent conditions such as pain, depression, anxiety, insomnia, irritable bowel syndrome, migraine, and Parkinson's disease. The positive and negative effects of clinicians' communication on patient outcomes pose important ethical issues, which we describe in this article under the label of "the ethics of therapeutic communication" (TC). We begin by reviewing available evidence supporting the claim that doctor-patient communication has therapeutic effects. We then identify in truthfulness, helpfulness, and pragmatism three morally relevant considerations that can guide clinicians in therapeutic communication with their patients. Finally, we examine the ethics of using TC to enhance the effectiveness of proven medical interventions and open-label placebos. PMID:27157112

  6. Polarization effects in optical fiber communication and distributed vibration sensing systems

    NASA Astrophysics Data System (ADS)

    Zhang, Ziyi

    This thesis includes studies of polarization effects in two main research areas of optical fiber technology: optical fiber communication systems and optical fiber sensors. Polarization of light in optical fiber is sensitive to environmental disturbances. On the negative side, this results in complex measurement processes and errors in communication systems caused by dynamic polarization mode dispersion (PMD) and polarization dependent loss (PDL). On the positive side though, it also results in the possibility of developing a distributed optical fiber vibration sensor. For the purpose of fast polarization measurement for high bit-rate communication systems, a new PDL vector method was proposed based on the equation of motion in Stokes space. It is capable of providing accurate PDL measurements while requiring less measurement steps compared with other available techniques. We had performed a PMD field test, and found the fastest PMD change in submarine fibers under the Caribbean Sea. With long measurement duration (>24h) on one pair of fiber, correlations between polarization effects and tides were reported for the first time. A histogram of the differential group delay (DGD) data and an auto-correlation function of state of polarization (SOP) and DGD were validated by theoretical fittings. The average and fastest drift time for both SOP and DGD was found to be ˜3min and less than 15s, respectively. Polarization effects were then utilized as a sensing parameter to detect and locate external disturbances along the optical fiber. A system based on polarization optical time domain reflectometry (Polarization-OTDR) technique was developed in order to pinpoint the disturbances as well as to give events' frequency information. For the first time, a fully distributed optical fiber vibration sensor has been demonstrated in a 1km fiber link with 10m spatial resolution and 5kHz maximum detectable frequency. Moreover, by our proposed spectrum analysis, multiple simultaneous

  18. Guidelines A Primer for Communicating Effectively with NABIR Stakeholders

    SciTech Connect

    Weber, James R.; Word, Charlotte J.; Bilyard, Gordon R.

    2002-03-15

    The purpose of this report is to help scientists communicate with stakeholders and the public (primarily nonscientists) about fundamental science research. The primary audience for this report is scientists involved in the Natural and Accelerated Bioremediation Research (NABIR) program of the U.S. Department of Energy. However, the information and insights in the report that are not program-specific should be helpful to scientists in other fundamental science research programs. The report first discusses why scientists should talk to stakeholders and the public, and the challenges associated with discussing the NABIR program. It is observed that communication initiatives can be characterized by three factors: relationships in the social environment, views of what constitutes communication, and accepted forms of communication practices and products. With a focus on informal science communication, recent efforts to gauge public understanding of science and the factors that affect public trust of science institutions are discussed. The social bases for scientist-nonscientist interactions are then examined, including possible sources of distrust and difficulties in transferring discussions of fundamental science from classrooms (where most of the public first learns about science) to public forums. Finally, the report contains specific suggestions for preparing, meeting, and following up on public interactions with stakeholders and the public, including themes common to public discussions of NABIR science and features of scientist-nonscientist interactions observed in interpersonal, small group, and large group interactions between NABIR scientists and stakeholders. A Quick Preparation Guide for Meeting NABIR Stakeholders is provided immediately following the Summary. It condenses some of the information and advice found in the text of the report.

  19. Child Effects on Communication between Parents of Youth with and without ADHD

    Wymbs, Brian T.; Pelham, William E.

    2010-01-01

    Numerous studies indicate interparental conflict causes child externalizing behavior. However, far less is known about the inverse relationship. Exploring this gap in the literature has clear implications for parents of children with externalizing disorders (e.g., attention-deficit hyperactivity disorder [ADHD]). Adapting an experimental child behavior manipulation paradigm (Lang et al., 1999; Pelham et al., 1997, 1998), parent couples of 9–12 year-old boys and girls with ADHD (n=51) and without ADHD (n=39) were randomly assigned to interact with a “disruptive” or “typical” confederate child. According to parent and observer ratings, parents communicated less positively and more negatively with each other during and after interactions with disruptive confederates than parents who interacted with typical confederates. Observational coding also indicated that child effects on negative interparental communication were more noticeable among parents of youth with ADHD, particularly those with comorbid oppositional-defiant disorder or conduct disorder, compared to parents of youth without ADHD. These findings extend results of prospective studies highlighting child effects on marital quality. PMID:20455609

    Yoo, Moon Sook; Chae, Sun-Mi

    2011-04-01

    The purpose of this study was to investigate the effects of video-based peer review on communication skills and learning motivation among nursing students. A non-equivalent control with pretest-posttest design was used. The participants were 47 sophomore nursing students taking a fundamentals of nursing course at a nursing college in Korea. Communication with a standardized patient was videotaped for evaluation. The intervention group used peer reviews to evaluate the videotaped performance; a small group of four students watched the videotape of each student and then provided feedback. The control group assessed themselves alone after watching their own videos. Communication skills and learning motivation were measured. The intervention group showed significantly higher communication skills and learning motivation after the intervention than did the control group. The findings suggest that peer review is an effective learning method for nursing students to improve their communication skills and increase their motivation to learn. PMID:21323255

  1. Comparative effectiveness research in the field of hand surgery

    Johnson, Shepard P.; Chung, Kevin C.

    2014-01-01

    Comparative Effectiveness Research (CER) is a concept initiated by the Institute of Medicine (IOM) and financially supported by the federal government. The primary objective of the CER is to improve decision making in medicine. This research is intended to evaluate the effectiveness, benefits, and harmful effects of alternative interventions. With encouragement from the IOM, CER studies are commonly large, simple, observational, and conducted using electronic databases. To date, there is little comparative effectiveness evidence within hand surgery to guide therapeutic decisions. A general discussion of CER will illuminate how it could make a beneficial impact. In order to draw conclusions on effectiveness through electronic health records, databases must contain clinical information and outcomes relevant to hand surgery interventions, such as patient-related outcomes (PRO). Unlike objective measures such as morbidity, mortality and physiological markers, PROs provide patients’ perspective on treatment benefit and can be the outcome of greatest importance. PMID:25066850

  3. Atmospheric channel effects on free-space laser communication

    NASA Astrophysics Data System (ADS)

    Ricklin, Jennifer C.; Hammel, Stephen M.; Eaton, Frank D.; Lachinova, Svetlana L.

    Free-space laser communication offers an attractive alternative for transferring high-bandwidth data when fiber optic cable is neither practical nor feasible. However, there are a variety of deleterious features of the atmospheric channel that may lead to serious signal fading, and even the complete loss of signal altogether. Physical obstructions—such as birds, insects, tree limbs, or other factors—can temporarily or permanently block the laser line-of-sight. Platform/building motion due to wind, differential heating and cooling, or ground motion over time can result in serious misalignment of fixed-position laser communication systems. But most importantly of all, absorption and scattering due to particulate matter in the atmosphere may significantly decrease the transmitted optical signal, while random atmospheric distortions due to optical turbulence can severely degrade the wave-front quality of a signal-carrying laser beam, causing intensity fading and random signal losses at the receiver.

  5. Free-space optical communication satellite networks-vibration effects and possible solutions

    NASA Astrophysics Data System (ADS)

    Arnon, Shlomi; Kopeika, Norman S.

    1997-07-01

    A number of serious consortiums develop satellite communication networks. The objective of these communication projects is to service personal communication users almost everywhere on earth. The inter satellite links in those project use microwave radiation as the carrier. Free space optical communication between satellites networked together can make possible high speed communications between different places on earth. The advantages of an optical communication system instead of a microwave communication system in free space are: (1) smaller size and weight, (2) less transmitter power, (3) larger bandwidth, (4) higher immunity to interference, and (5) smaller transmitter beam divergence. The use of optical radiation as a carrier between the satellites creates very narrow beam divergence angles. Due to the narrow beam divergence angle and the large distance between the satellites the pointing from one satellite to another is complicated. The problem is more complicated due to vibration of the pointing system caused by two stochastic fundamental mechanisms (1) tracking noise created by the electrooptic tracker and (2) vibrations created by internal and external mechanical mechanisms. The vibrations displace the transmitted beam in the receiver plane. Such movement of the transmitted beam in the receiver plane decreases the average received signal which decreases increases the bit error rate. In this paper we review: (1) the present status of satellite networks, (2) developing efforts of optical satellite communication around the world, (3) performance results of vibration effects on different kinds of optical communication satellite networks and (4) seven approaches to overcome the problems caused by transmitter pointing vibration.

  6. Using Visualization Science to Evaluate Effective Communication of Climate Indicators

    NASA Astrophysics Data System (ADS)

    Gerst, M.; Kenney, M. A.; Wolfinger, F.; Lloyd, A.

    2015-12-01

    Indicators are observations or calculations that are used to track social and environmental conditions over time. For a large coupled system such as the economy and environment, the choice of indicators requires a structured process that involves co-production among facilitators, subject-matter experts, decision-makers, and the general public. This co-production is needed in part because such indicators serve a duel role of scientifically tracking change and of communicating to non-scientists important changes and information that may be useful in decision contexts. Because the goal is to communicate and inform decisions it is critical that indicators be understood by non-scientific audiences, which may require different visualization techniques than for scientific audiences. Here we describe a process of rigorously evaluating visual communication efficacy by using a simplified taxonomy of visualization design problems and trade-offs to assess existing and redesigned indicator images. The experimental design is three-part. It involves testing non-scientific audiences' understandability of scientific images found in the literature along with similar information shaped by a partial co-production process that informed the U.S. Global Change Research Program prototype indicators system, released in Spring 2015. These recommendations for physical, natural, and societal indicators of changes and impacts involved input from over 200 subject-matter experts, organized into 13 technical teams. Using results from the first two parts, we then explore visualization design improvements that may increase understandability to non-scientific audiences. We anticipate that this work will highlight important trade-offs in visualization design when moving between audiences that will be of great use to scientists who wish to communicate their results broader audiences.

    2015-11-01

    One of the provisions of the health care reform legislation in 2010 was for funding pragmatic clinical trials or large observational studies for comparing the effectiveness of different approved medical treatments, involving broadly representative patient populations. After reviewing pragmatic clinical trials and the issues and challenges that have made them just a small fraction of comparative effectiveness research (CER), we focus on a recent development that uses point-of-care (POC) clinical trials to address the issue of "knowledge-action gap" in pragmatic CER trials. We give illustrative examples of POC-CER trials and describe a trial that we are currently planning to compare the effectiveness of newly approved oral anticoagulants. We also develop novel stage-wise designs of information-rich POC-CER trials under competitive budget constraints, by using recent advances in adaptive designs and other statistical methodologies.

  8. Advantages of Parallel Processing and the Effects of Communications Time

    NASA Technical Reports Server (NTRS)

    Eddy, Wesley M.; Allman, Mark

    2000-01-01

    Many computing tasks involve heavy mathematical calculations, or analyzing large amounts of data. These operations can take a long time to complete using only one computer. Networks such as the Internet provide many computers with the ability to communicate with each other. Parallel or distributed computing takes advantage of these networked computers by arranging them to work together on a problem, thereby reducing the time needed to obtain the solution. The drawback to using a network of computers to solve a problem is the time wasted in communicating between the various hosts. The application of distributed computing techniques to a space environment or to use over a satellite network would therefore be limited by the amount of time needed to send data across the network, which would typically take much longer than on a terrestrial network. This experiment shows how much faster a large job can be performed by adding more computers to the task, what role communications time plays in the total execution time, and the impact a long-delay network has on a distributed computing system.

    In each of two experiments, the comparative instructions in a symbolic comparison task were either varied randomly from trial to trial (mixed blocks) or left constant (pure blocks) within blocks of trials. In the first experiment, every stimulus was compared with every other stimulus. The symbolic distance effect (DE) was enhanced, and the semantic congruity effect (SCE) was significantly larger, when the instructions were randomized than when they were blocked. In a second experiment, each stimulus was paired with only one other stimulus. The SCE was again larger when instructions were randomized than when they were blocked. The enhanced SCE and DE with randomized instructions follow naturally from evidence accrual views of comparative judgments. PMID:16686118

    Current onboard communication architectures are based upon an all-in-one communications management unit. This unit and associated radio systems has regularly been designed as a one-off, proprietary system. As such, it lacks flexibility and cannot adapt easily to new technology, new communication protocols, and new communication links. This paper describes the current avionics communication architecture and provides a historical perspective of the evolution of this system. A new onboard architecture is proposed that allows full use of commercial-off-the-shelf technologies to be integrated in a modular approach thereby enabling a flexible, cost-effective and fully deployable design that can take advantage of ongoing advances in the computer, cryptography, and telecommunications industries.

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

    NASA Astrophysics Data System (ADS)

    2016-04-01

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

  18. The exposure advantage: Early exposure to a multilingual environment promotes effective communication

    PubMed Central

    Fan, Samantha P.; Liberman, Zoe; Keysar, Boaz; Kinzler, Katherine D.

    2016-01-01

    Early language exposure is essential to developing a formal language system, but may not be sufficient for communicating effectively. To understand a speaker’s intention, one must take the speaker’s perspective. Multilingual exposure may promote effective communication by enhancing perspective taking. We tested children on a task that required perspective taking to interpret a speaker’s intended meaning. Monolingual children failed to interpret the speaker’s meaning dramatically more often than bilingual children and children who were exposed to a multilingual environment but were not bilinguals themselves. Children who were merely exposed to a second language performed as well as bilingual children, despite having lower executive function scores. Thus, communicative advantages may be social in origin, and not due to enhanced executive control. For millennia, multilingual exposure has been the norm. Our study shows that such an environment may facilitate the development of perspective-taking tools that are critical for effective communication. PMID:25956911

    On 11 March 2011, an undersea earthquake of magnitude 9.0, the largest ever recorded in Japan, occurred off the Oshika Peninsula on the Pacific coast of the Tohoku region. The hypocentral region extended for 500 km in the north-south direction from Iwate Prefecture to Ibaraki Prefecture, and for 200 km in east-west direction. The earthquake generated a tsunami with a height of more than 10 m and a run-up height of up to 40.0 m in certain places, which inflicted devastating damage on the coastal areas of the Tohoku and Kanto regions. In addition to the tsunami, the earthquake caused shaking, liquefaction, subsidence, and the collapse of dams, causing major damage to vast areas in the Tohoku and Kanto regions and disrupting various types of infrastructure, including communication. In light of this unprecedented damage, satellite communications were important from various perspectives while terrestrial communications systems were damaged, and an objective evaluation of the role played by satellite communications is relevant to its future installation, adoption and use as a standalone or backup system. Furthermore, satellite communications can help reduce the extent of damage, particularly damage to communications systems, inflicted by strong earthquakes in the future. Accordingly, we report a preliminary quantitative evaluation of the role of satellite communications in the Great East Japan Earthquake, of the role of satellite communications if it becomes widespread, and of its expected role in future large-scale earthquakes in terms of the economic effect converted into cost.

    The highly complex and controversial topic of vaccine safety communication warrants innovative, user-centered solutions that would start with gaining mutual respect while taking into account the needs, concerns and underlying motives of patients, parents and physicians. To this end, a non-profit collaborative project was conducted by The Vienna Vaccine Safety Initiative, an international think tank aiming to promote vaccine safety research and communication, and the School of Design Thinking in Potsdam, Germany, the first school for innovation in Europe. The revolutionary concept of the Design Thinking approach is to group students in small multi-disciplinary teams. As a result they can generate ground-breaking ideas by combining their expertise and different points of view. The team agreed to address the following design challenge question: "How might we enable physicians to encourage parents and children to prevent infectious diseases?" The current article describes, step-by step, the ideation and innovation process as well as first tangible outcomes of the project. PMID:25859673

    Background. Policy makers require estimates of comparative effectiveness that apply to the population of interest, but there has been little research on quantitative approaches to assess and extend the generalizability of randomized controlled trial (RCT)–based evaluations. We illustrate an approach using observational data. Methods. Our example is the Whole Systems Demonstrator (WSD) trial, in which 3230 adults with chronic conditions were assigned to receive telehealth or usual care. First, we used novel placebo tests to assess whether outcomes were similar between the RCT control group and a matched subset of nonparticipants who received usual care. We matched on 65 baseline variables obtained from the electronic medical record. Second, we conducted sensitivity analysis to consider whether the estimates of treatment effectiveness were robust to alternative assumptions about whether “usual care” is defined by the RCT control group or nonparticipants. Thus, we provided alternative estimates of comparative effectiveness by contrasting the outcomes of the RCT telehealth group and matched nonparticipants. Results. For some endpoints, such as the number of outpatient attendances, the placebo tests passed, and the effectiveness estimates were robust to the choice of comparison group. However, for other endpoints, such as emergency admissions, the placebo tests failed and the estimates of treatment effect differed markedly according to whether telehealth patients were compared with RCT controls or matched nonparticipants. Conclusions. The proposed placebo tests indicate those cases when estimates from RCTs do not generalize to routine clinical practice and motivate complementary estimates of comparative effectiveness that use observational data. Future RCTs are recommended to incorporate these placebo tests and the accompanying sensitivity analyses to enhance their relevance to policy making. PMID:25986472

    There is an enormous unmet need for knowledge about how new insights from discovery and translational research can yield measurable, population-level improvements in health and reduction in mortality among those having or at risk for neurological disease. Once several, well-conducted randomized controlled trials establish the efficacy of a given therapy, implementation research can generate new knowledge about barriers to uptake of the therapy into widespread clinical care, and what strategies are effective in overcoming those barriers and in addressing health disparities. Comparative effectiveness research aims to elucidate the relative value (including clinical benefit, clinical harms, and/or costs) of alternative efficacious management approaches to a neurological disorder, generally through direct comparisons, and may include comparisons of methodologies for implementation. Congress has recently appropriated resources and established an institute to prioritize funding for such research. Neurologists and neuroscientists should understand the scope and objectives of comparative effectiveness and implementation research, their range of methodological approaches (formal literature syntheses, randomized trials, observational studies, modeling), and existing research resources (centers for literature synthesis, registries, practice networks) relevant to research for neurological conditions, in order to close the well-documented “evidence-to-practice gap.” Future directions include building this research resource capacity, producing scientists trained to conduct rigorous comparative effectiveness and implementation research, and embracing innovative strategies to set research priorities in these areas.

    Wireless sensor networks (WSN) have been studied in a variety of scenarios over recent years, but work has almost exclusively been done using air as the transmission media. In this article some of the challenges of deploying a WSN in a heterogeneous biomass, in this case silage, is handled. The dielectric constant of silage is measured using an open-ended coaxial probe. Results were successfully obtained in the frequency range from 400 MHz to 4 GHz, but large variations suggested that a larger probe should be used for more stable results. Furthermore, the detuning of helix and loop antennas and the transmission loss of the two types of antennas embedded in silage was measured. It was found that the loop antenna suffered less from detuning but was worse when transmitting. Lastly, it is suggested that taking the dielectric properties of silage into account during hardware development could result in much better achievable communication range. PMID:22164076

    The need to effectively communicate HIV/AIDS messages in South Africa, given the high prevalence of the pandemic, cannot be overemphasised. Communication scholars have long emphasised the need to recognise adherence to cultural norms of target communities as catalyst for effective HIV/AIDS communication. Unfortunately this call has not been totally heeded by the designers of HIV/AIDS communication instruments. In the case of theatre, research has shown that in South Africa, theatre groups have gone into communities with pre-packaged plays without due cognisance of the cultural norms and beliefs of the target population. This research was conducted in KwaZulu-Natal (the province with the highest prevalence rate of HIV/AIDS infection in South Africa). Using a qualitative research methodology this paper investigated the inclusion/non-inclusion of the cultural norms of the target population in the design of the dramatic performance by the theatre group in its HIV/AIDS campaigns. The findings indicate that while the group did try to incorporate aspects of the cultural norms of the target population, it did so at a level that failed to effectively communicate the HIV/AIDS message to its audiences. This paper therefore seeks to show through empirical evidence that the non-inclusion of cultural norms and values of the target population has acted as a stumbling block in the effective communication of HIV/AIDS messages by theatre groups in the country.

    Climate change is a complex environmental problem that can be used to examine students' understanding, gained through classroom communication, of climate change and its interactions. The present study examines a series of four science sessions given to a group of primary school student teachers (n = 20). This includes analysis of the communication styles used and the students' pre- and post-conceptualisation of climate change based on results obtained via essay writing and drawings. The essays and drawings concerned the students' unprompted pre- and post-conceptions about climate change, collected before and after each of the four inquiry-based science sessions (in physics, chemistry, biology and geography). Concept mapping was used in the analysis of the students' responses. The communication used in the four sessions was analysed with a communicative approach in order to find out the discussion about climate change between teacher and students. The analyses indicated that the students did not have the knowledge or the courage to participate in discussion, but post-conceptualisation map showed that students' thinking had become more coherent after the four sessions. Given the results of the present study, proposals for using concepts maps and/or communication analysis in studying students' conceptions are presented.

    Healthcare is delivered in an extraordinary complex environment. Despite highly skilled, dedicated clinicians, there are currently unacceptably high levels of communication failures and adverse events. Effective teamwork, in conjunction with reliable processes of care, is essential for the consistent delivery of high-quality care. Practical concepts and tools are provided that address the team behaviors of structured communication, effective assertion/critical language, psychological safety, situational awareness, and effective leadership. Examples of the mounting clinical evidence of improved patient outcomes and reduced harm resulting from effective teamwork training are cited. PMID:22069205

    2016-01-01

    One of the important components of patient-centered healthcare is comparative effectiveness research (CER), which aims at generating evidence from the real-life setting. The primary purpose of CER is to provide comparative information to the healthcare providers, patients, and policy makers about the standard of care available. This involves research on clinical questions unanswered by the explanatory trials during the regulatory approval process. Main methods of CER involve randomized controlled trials and observational methods. The limitations of these two methods have been overcome with the help of new statistical methods. After the evidence generation, it is equally important to communicate the results to all the interested organizations. CER is beginning to have its impact in the clinical practice as its results become part of the clinical practice guidelines. CER will have far-reaching scientific and financial impact. CER will make both the treating physician and the patient equally responsible for the treatment offered. PMID:26955571

    Chloramine-T (sodium p-toluene sulfonchloramide) was a good surface sterilant for Ditylenchus dipsaci, however it was somewhat nematicidal. These properties were presumably associated with its properties as an oxidizing chlorine. Other chloramines tested were also toxic. Its possible use as a nematicide is suggested in relation to dosage and phytotoxicity. The comparative effects of chloramines on a wide range of freeliving soil nematodes and freeliving infective larvae of animal parasitic forms are included. PMID:19325651

    Previous research has documented that Asians tend to somatize negative experiences to a greater degree than Westerners. It is posited that somatization may be a more functional communication strategy in Korean than American context. We examined the effects of somatization in communications of distress among participants from the US and Korea. We predicted that the communicative benefits of somatic words used in distress narratives would depend on the cultural contexts. In Study 1, we found that Korean participants used more somatic words to communicate distress than US participants. Among Korean participants, but not US participants, use of somatic words predicted perceived effectiveness of the communication and expectations of positive reactions (e.g., empathy) from others. In Study 2, we found that when presented with distress narratives of others, Koreans (but not Americans) showed more sympathy in response to narratives using somatic words than narratives using emotional words. These findings suggest that cultural differences in use of somatization may reflect differential effectiveness of somatization in communicating distress across cultural contexts. PMID:27047414

    Birds provide very useful models for understanding the effects of noise on hearing and acoustic communication. They are excellent subjects for laboratory studies of hearing in which signals and noise can be precisely defined and delivered and behavioral responses can be unambiguously interpreted. For this reason, a huge amount is already known about their hearing. Acoustic communication is critically important for most species of birds and some even acquire their communication signals through vocal learning. For this reason, a lot is already known about how birds perceive complex acoustic signals such as vocalizations. Drawing from both field and laboratory studies, we review what is known about the effects of noise on hearing and vocal communication in birds. This includes the effects of intense noise on the ear, the effects of background noise on the detection and discrimination of both simple sounds and complex vocalizations, and the spatial effects of signal detection in noise in the free-field. As a whole, these studies show that birds are resistant to damage and interference from noise and have developed a variety of strategies to effectively communicate.

    Communication is the process of exchanging and relaying vital information that has bearing on the effectiveness of all phases of emergency management: mitigation, preparedness, response, and recovery, making it one of the most important activities in disasters. Lack of communication between emergency managers, policy makers, and communities at risk may result in an inability to accurately identify disaster risk, and failure to determine priorities during a hazard event. Specific goals of communication change during the four phases of emergency management. Consequently, the communication strategy changes as well. Communication strategy also depends on a variety of attitudinal and motivational characteristics of the population at risk, as well as socioeconomic, cultural, and geographical features of the disaster-prone region. In May 2013, insufficient communication patterns between federal, state, tribal agencies, and affected communities significantly contributed to delays in the flood response and recovery in several rural villages along the Yukon River in central Alaska. This case study finds that long term dialogue is critical for managing disaster risk and increasing disaster resilience in rural Northern communities. It introduces new ideas and highlights best practices in disaster communication.

    Background Healthcare expenditures in the United States exceed the healthcare expenditures of other countries, yet relatively unfavorable health outcomes persist. Despite the emergence of numerous evidence-based interventions, wide variations in clinical care have caused disparities in quality of care and cost. Comparative effectiveness and cost effectiveness research may better guide healthcare decisionmakers in determining which interventions work best, for which populations, under which conditions, and at what cost. Methods This article reviews national health policies that promote comparative effectiveness research (CER), healthcare decisionmaker roles in CER, methodological approaches to CER, and future implications of CER. Results This article provides a brief summary of CER health policy up to the Patient Protection and Affordable Care Act and its establishment of the Patient-Centered Outcomes Research Institute (PCORI). Through PCORI, participatory methods for engaging healthcare decisionmakers in the entire CER process have gained momentum as a strategy for improving the relevance of research and expediting the translation of research into practice. Well-designed, methodologically rigorous observational studies and randomized trials conducted in real-world settings have the potential to improve the quality, generalizability, and transferability of study findings. Conclusion Learning health systems and practice-based research networks provide the infrastructure for advancing CER methods, generating local solutions to high-quality cost-effective care, and transitioning research into implementation and dissemination science—all of which will ultimately guide health policy on clinical care, payment for care, and population health.

    With the recent allocation ofa $1.1 billion "down payment" to fund comparative effectiveness research (CER) from the American Recovery and Reinvestment Act of 2009 (generally referred to as the stimulus package) and with $300 million being allocated for the Agency for Healthcare Research and Quality (AHRQ), $400 million for the National Institutes of Health, and $400 million for allocation at the discretion of the Secretary of Health and Human Services and with the National Center for Complementary Alternative Medicine putting out a request for research proposals for Comparative Effectiveness Studies of Complementary and Alternative Medicine, it is safe to say CER has entered a new era. CER solves two historical concerns for complementary and alternative medicine (CAM) researchers; first it focuses on effectiveness not efficacy; second it tests holistic approaches to care. Because it allows the providers to give care in any way they choose, it avoids the problem of reductionism inherent in standard random controlled trials. In CER, the provider can continue to practice holistically and to use individualized medicine to treat the patient. However, amid the largely positive responses to this move among researches in CAM, a more critical evaluation might be in order. This article argues that while the move to effectiveness research is a positive move for CAM, CER as currently being talked about and funded may just be a new form of privileging certain forms of evidence at the expense of other equally important and perhaps more relevant evidence.

    2013-01-01

    Purpose: Communicating about the end of life with patients has been reported as one of the most difficult and stressful part of the work of oncologists. Despite this fact, oncologists receive little training in this area, and many do not communicate effectively with patients. The purpose of this analysis, part of a larger study examining oncologists' experiences of patient loss, was to explore oncologists' communication strategies and communication barriers when discussing end-of-life issues with patients. Methods: Twenty oncologists were interviewed at three hospitals about their communication strategies on end-of-life issues with patients. The data were analyzed using the grounded theory method. Results: The findings revealed the strategies to effective communication about the end of life included: being open and honest; having ongoing, early conversations; communicating about modifying treatment goals; and balancing hope and reality. Barriers to implementing these strategies fell broadly into three domains, including physician factors, patient factors, and institutional factors. Physician factors included difficulty with treatment and palliation, personal discomfort with death and dying, diffusion of responsibility among colleagues, using the “death-defying mode,” lack of experience, and lack of mentorship. Patient factors included, patients and/or families being reluctant to talk about the end of life, language barriers, and younger age. Institutional factors included stigma around palliative care, lack of protocol about end-of-life issues; and lack of training for oncologists on how to talk with patients about end-of-life issues. Conclusion: We conclude by drawing implications from our study and suggest that further research and intervention are necessary to aid oncologists in achieving effective communication about end-of-life issues.

  4. Cost-effectiveness prospects of picture archiving and communication systems.

    PubMed

    Hindel, R; Preger, W

    1988-01-01

    PAC (picture archiving and communication) systems are widely discussed and promoted as the organizational solution to digital image management in a radiology department. For approximately two decades digital imaging has increasingly been used for such diagnostic modalities as CT, DSA, MRI, DR (Digital Radiography) and others. PACS are seen as a step toward high technology integration and more efficient management. Although the acquisition of such technology is investment intensive, there are well-founded projections that prolonged operation will prove cost justified. Such justification can only partly be derived from cost reduction through PAC with respect to present department management--the major justification is preparation for future economic pressures which could make survival of a department without modern technology difficult. Especially in the United States the political climate favors 'competitive medicine' and reduced government support. Seen in this context PACS promises to speed the transition of Health Care Services into a business with tight resource management, cost accounting and marketing. The following paper analyzes cost and revenue in a typical larger Radiology Department, projects various scenarios of cost reduction by means of digital technology and concludes with cautious optimism that the investment expenses for a PACS will be justified in the near future by prudent utilization of high technology.

    Objective To compare effectiveness of three surfactant preparations (beractant, calfactant, and poractant alpha) in premature infants for preventing three outcomes: (1) air leak syndromes; (2) death; and (3) bronchopulmonary dysplasia (BPD) or death (composite outcomes). Study design We conducted a comparative effectiveness study of premature infants admitted to 322 neonatal intensive care units in the U.S. from 2005–2010 who were treated with beractant, calfactant, or poractant alfa. We compared the incidence of air leak syndromes, death, and bronchopulmonary dysplasia (BPD) or death, adjusting for gestational age, antenatal steroids, discharge year, and small-for-gestational-age status. Results 51,282 infants received surfactant; 40% received beractant, 30% calfactant, and 30% poractant alfa. Median birth weight was 1435 g (interquartile range 966–2065); median gestational age was 30 weeks (27–33). On adjusted analysis, we observed a similar risk of air leak syndromes (calfactant vs. beractant odds ratio [OR]=1.17 [95% confidence interval: 0.95, 1.43]; calfactant vs. poractant OR=1.23 [0.98, 1.56]; beractant vs. poractant OR=1.06 [0.87, 1.29]), death (calfactant vs. beractant OR=1.14 [0.93, 1.39]; calfactant vs. poractant OR=0.98 [0.78, 1.23]; beractant vs. poractant OR=0.86 [0.72, 1.04]), and BPD or death (calfactant vs. beractant OR=1.08 [0.93, 1.26]; calfactant vs. poractant OR=1.19 [1.00, 1.41]; beractant vs. poractant OR=1.10 [0.96, 1.27]). Conclusions Beractant, calfactant, and poractant alfa demonstrated similar effectiveness in prevention of air leak syndromes, death, and BPD or death in premature infants when adjusted for site. Previously described differences in mortality between surfactants likely do not represent true differences in effectiveness but may relate to site variation in outcomes. PMID:23769501

    Understanding the environmental effects of alternative fuel production is critical to characterizing the sustainability of energy resources to inform policy and regulatory decisions. The magnitudes of these environmental effects vary according to the intensity and scale of fuel production along each step of the supply chain. We compare the scales (i.e., spatial extent and temporal duration) of ethanol and gasoline production processes and environmental effects based on a literature review, and then synthesize the scale differences on space-time diagrams. Comprehensive assessment of any fuel-production system is a moving target, and our analysis shows that decisions regarding the selection of spatial and temporal boundaries of analysis have tremendous influences on the comparisons. Effects that strongly differentiate gasoline and ethanol supply chains in terms of scale are associated with when and where energy resources are formed and how they are extracted. Although both gasoline and ethanol production may result in negative environmental effects, this study indicates that ethanol production traced through a supply chain may impact less area and result in more easily reversed effects of a shorter duration than gasoline production.

    Recent studies suggest that cardiorespiratory fitness (CRF) mitigates the brain's atrophy typically associated with aging, via a variety of beneficial mechanisms. One could argue that if CRF is generally counteracting the negative effects of aging, the same regions that display the greatest age-related volumetric loss should also show the largest beneficial effects of fitness. To test this hypothesis we examined structural MRI data from 54 healthy older adults (ages 55-87), to determine the overlap, across brain regions, of the profiles of age and fitness effects. Results showed that lower fitness and older age are associated with atrophy in several brain regions, replicating past studies. However, when the profiles of age and fitness effects were compared using a number of statistical approaches, the effects were not entirely overlapping. Interestingly, some of the regions that were most influenced by age were among those not influenced by fitness. Presumably, the age-related atrophy occurring in these regions is due to factors that are more impervious to the beneficial effects of fitness. Possible mechanisms supporting regional heterogeneity may include differential involvement in motor function, the presence of adult neurogenesis, and differential sensitivity to cerebrovascular, neurotrophic and metabolic factors.

    Background Parkinson’s disease (PD) is a complex neurodegenerative disease with vocal communication deficits that manifest early, progress, and are largely resistant to medical interventions; however, they do respond to exercise-based speech and voice therapies. Objective and Methods To study how exercise-based vocal treatment can affect the progression of communication deficits related to PD, we studied ultrasonic vocalizations (USVs) in rats with homozygous knockout (−/−) of PINK1, a gene mutation known to cause PD, under the manipulation of a behavioral vocal exercise paradigm that allows us to precisely control dose and timing of exercise in the prodromal (prior to diagnosis) stages. Results We show that intensive vocal-training rescues frequency range and intensity deficits as well as leads to an increase in call complexity and duration of calls compared to sham-training; however, over time this training regime loses significant effect as the disease progresses. We also show effects of frequent handling and conspecific (male-female) interaction in the sham-training group as they demonstrated significantly higher call rate, intensity, frequency range, and call complexity compared to rats without any form of training and consequently less handling/interaction. Further, we confirm that this model exhibits progressive gross motor deficits that indicate neurodegeneration. Discussion This study suggests that the evolving nature of vocal communication deficits requires an adjustment of therapy targets and more intensive training over the course of this progressive disease and demonstrates the importance of frequent social experiences.

    Defining comparative effectiveness research (CER) was the first order of business for the Institute of Medicine Committee on Initial Priorities for CER. The Institute of Medicine committee approached the task of defining CER by identifying the common theme in the 6 extant definitions. The definition follows: "Comparative effectiveness research is the generation and synthesis of evidence that compares the benefits and harms of alternative methods to prevent, diagnose, treat, and monitor a clinical condition or to improve the delivery of care. The purpose of CER is to assist consumers, clinicians, purchasers, and policy makers to make informed decisions that will improve health care at both the individual and population levels." The key words in this definition are "generation and synthesis of evidence" (which implies both original research and systematic reviews), "alternative methods" (which implies making head to head comparisons in study populations typical of daily practice), and "to make informed decisions" (which implies a focus on data that helps to decide between alternatives). Defining CER requires us to decide what we want from decisions about health care. Definitions also serve a bureaucratic function: they can set boundaries that delineate which research is eligible for CER program funding. Definitions--and the funding that advances their goals--can reshape the research environment. PMID:20473202

    This study evaluated the effects of Communications Delays and Winds on Air Traffic Controller ratings of acceptability of horizontal miss distances (HMDs) for encounters between UAS and manned aircraft in a simulation of the Dallas-Ft. Worth East-side airspace. Fourteen encounters per hour were staged in the presence of moderate background traffic. Seven recently retired controllers with experience at DFW served as subjects. Guidance provided to the UAS pilots for maintaining a given HMD was provided by information from self-separation algorithms displayed on the Multi-Aircraft Simulation System. Winds tested did not affect the acceptability ratings. Communications delays tested included 0, 400, 1200, and 1800 msec. For longer communications delays, there were changes in strategy and communications flow that were observed and reported by the controllers. The aim of this work is to provide useful information for guiding future rules and regulations applicable to flying UAS in the NAS.

    The results of an investigation to develop a methodology for evaluating crew communication behavior on the flight deck and a flight simulator experiment to test the effects of crew member expressivity, as measured by the Personal Attributes Questionnarie, and flight task on crew communication and flight performance are discussed. A methodology for coding and assessing flight crew communication behavior as well as a model for predicting that behavior is advanced. Although not enough crews were found to provide valid statistical tests, the results of the study tend to indicate that crews in which the captain has high expressivity perform better than those whose captain is low in expressivity. There appears to be a strong interaction between captains and first officers along the level of command dimension of communication. The PAQ appears to identify those pilots who offer disagreements and inititate new subjects for discussion.

  16. A Clinical Communication Strategy to Enhance Effectiveness and CAHPS Scores: The ALERT Model

    2008-01-01

    The Consumer Assessment of Healthcare Providers and Systems (CAHPS) program is a national annual report that surveys patients and rates health plans on a variety of metrics, including claims processing, customer service, office staff helpfulness, and ability to get needed care. Although physicians may feel they have no immediate control over many aspects of this questionnaire, there is an important area of the survey where they do have direct control: “how well the doctor communicates.” It is well established that effective physician–patient communication has beneficial effects not only on physician and patient satisfaction but also on adherence to medical advice, diagnostic accuracy, and malpractice risk. The creators of the CAHPS survey developed and incorporated four questions seeking to ascertain the patient's impression of the physician's communication skills. These questions assess how well the physician listened carefully to the patient, how often the physician explained things understandably, how often the physician showed respect for what the patient said, and how often the physician spent enough time with the patient. Many excellent clinical communication models exist that touch on aspects of the CAHPS topics, but it behooves physicians to be mindful of the exact survey questions. The ALERT model of communication was developed to facilitate physicians' recall of these measures. By incorporating key verbal and nonverbal communication skills, clinicians can address and improve their scores on this important area of the CAHPS survey. PMID:21331215

    Objective This study examined parenting variables (communication, monitoring) as moderators of a family-based intervention for reducing sedentary behavior (SB) in African American adolescents. As a secondary aim, a similar model was tested using adolescent weight status as the outcome. Methods African American adolescents (n = 73; 12.45 ± 1.45 years; 60% girls; 63% overweight/obese) and caregivers were randomized to a 6-week interactive, parent-based intervention or general health condition. Parent–adolescent communication and monitoring of health behaviors were self-reported by parents. Adolescent SB was self-reported by youth. Results There was a significant intervention by communication interaction, such that intervention families with more positive communication showed lower adolescent SB than those with less positive communication or those in the comparison condition. No effects were found for monitoring on SB or for the model with weight status as the outcome. Conclusions Parent–adolescent communication may be an effective component to integrate into health promotion programs for African American adolescents.

    2014-01-01

    Abstract Complementary and integrative medicine (CIM) is becoming an increasingly popular and visible component of oncology care. Many patients affected by cancer and their family members are looking for informed advice and desire communication with their physicians about CIM use. Patients affected by cancer come to discuss CIM use with intense emotions and are experiencing an existential crisis that cannot be ignored. Effective communication is crucial in establishing trust with these patients and their families. Communication is now recognized as a core clinical skill in medicine, including cancer care, and is important to the delivery of high-quality care. The quality of communication affects patient satisfaction, decision-making, patient distress and well-being, compliance, and even malpractice litigation. The communication process about CIM use requires a very sensitive approach that depends on effective communication skills, such as experience in listening, encouraging hope, and ability to convey empathy and compassion. This process can be divided into two parts: the “how” and the “what”. The “how” relates to the change in clinician attitude, the process of gathering information, addressing patients' unmet needs and emotions, and dealing with uncertainty. The “what” relates to the process of information exchange while assisting patients in decisions about CIM use by using reliable information sources, leading to informed decision-making.

    Objective Recent studies suggest that parents maintain influence as their adolescents transition into college. Advances in communication technology make frequent communication between parents and college students easy and affordable. This study examines the protective effect of parent-college student communication on student drinking behaviors, estimated peak blood alcohol concentration (eBAC), and serious negative consequences of drinking. Participants Participants were 746 first-year, first-time, full-time students at a large university in the U.S. Methods Participants completed a baseline and 14 daily web-based surveys. Results The amount of time spent communicating with parents on weekend days predicted the number of drinks consumed, heavy drinking, and peak eBAC consistent with a protective within-person effect. No association between communication and serious negative consequences was observed. Conclusions Encouraging parents to communicate with their college students, particularly on weekend days, could be a relatively simple, easily implemented protective process to reduce dangerous drinking behaviors.

    Effective communication of probabilistic forecasts for weather and climate applications is vital for improved understanding and decision making by the public and other end-users. Probabilistic predictions are frequently produced for uses such as hurricane warnings or climate change impact assessments, usually using ensemble prediction systems, but limited research has been undertaken to explore the best methods of communicating this information. The communication of forecasts produced by ensemble prediction systems is one of the major challenges facing meteorologists today. Most, if not all, of ensemble output is not currently communicated to the general public, leading to a widening gap between what information is computed and what is provided. A lack of public understanding and the difficulty in presenting such complex probabilistic information are two reasons often cited for not communicating ensemble weather forecasts to the public. Using an online game we explore these issues by evaluating the ability of participants to make decisions using a number of different methods of presenting probabilistic temperature and rainfall predictions. Participants are segmented demographically to better understand how outcomes vary between audiences of different backgrounds and levels of expertise. The insights gained from this work on day to day weather forecasts have implications for effective communication across the wider ensemble modeling community.

    "Comparative effectiveness research" (CER) is not a new concept; however, recently it has been popularized as a method to develop scientifically sound actionable data by which patients, physicians, payers, and policymakers may make informed health care decisions. Fundamental to CER is that the comparative data are derived from large diverse populations of patients assembled from point-of-care general primary care practices and that measured outcomes include patient value judgments. The challenge is to obtain scientifically valid data to be acted upon by decision-making stakeholders with potentially quite diversely different agenda. The process requires very thoughtful research designs modulated by complex statistical and analytic methods. This article is composed of a guiding narrative with an extensive set of tables outlining many of the details required in performing and understanding CER. It ends with short discussions of three example papers, limitations of the method, and how a practicing physician may view such reports. PMID:24098005

    Pulmonary arterial hypertension (PAH) is a disease that imposes a significant burden on patients. Although multiple treatment options for PAH are available, head-to-head comparisons are difficult to conduct. Network meta-analysis (NMA) can be a useful alternative for direct comparison to estimate the relative effectiveness of multiple treatments. The objective of the present study was to conduct a systematic review and NMA to evaluate the relative effectiveness among oral PAH medications.Data collection was performed by searching the Cochrane Central Register of Controlled Trials (CENTRAL) and Ichushi-Web. Randomized controlled trials (RCTs) assessing at least 1 of the following 3 outcome measurements; 6-minute walk distance test (6MWD), WHO functional class (WHOFC), and mean pulmonary artery pressure (mPAP) were included (PROSPERO registration number: CRD42015016557). Outcomes were evaluated by estimating the differences in the mean change from baseline or by estimating the odds ratios. Analyses were performed using WinBUGS 1.4.3.Seven double-blind RCTs were eligible. NMA results showed similar improvements in 6MWD for all medications assessed. Bosentan and sildenafil caused a statistically significant improvement in WHOFC compared to other medications.The relative effectiveness of oral PAH medications could be compared using NMA, which suggested the superiority of bosentan and sildenafil in the improvement of WHOFC.

    The United States lacks a system to use routinely collected electronic health record (EHR) clinical data to conduct comparative effectiveness research (CER) on pediatric drug therapeutics and other child health topics. This Special Article describes the creation and details of a network of EHR networks devised to use clinical data in EHRs for conducting CER, led by the American Academy of Pediatrics Pediatric Research in Office Settings (PROS). To achieve this goal, PROS has linked data from its own EHR-based "ePROS" network with data from independent practices and health systems across the United States. Beginning with 4 of proof-of-concept retrospective CER studies on psychotropic and asthma medication use and side effects with a planned full-scale prospective CER study on treatment of pediatric hypertension, the Comparative Effectiveness Research Through Collaborative Electronic Reporting (CER(2)) collaborators are developing a platform to advance the methodology of pediatric pharmacoepidemiology. CER(2) will provide a resource for future CER studies in pediatric drug therapeutics and other child health topics. This article outlines the vision for and present composition of this network, governance, and challenges and opportunities for using the network to advance child health and health care. The goal of this network is to engage child health researchers from around the United States in participating in collaborative research using the CER(2) database. PMID:26101357

    Background Intensity-modulated radiotherapy (IMRT) is increasingly used for treating localized prostate cancer. While allowing for the delivery of higher doses of radiation to the prostate, its effectiveness compared to the prior standard, 3-dimensional conformal therapy (3D-CRT), is uncertain. Objective To examine the comparative effectiveness of IMRT relative to 3D-CRT. Design, setting, and participants We performed a population-based cohort study using Surveillance, Epidemiology, and End Results (SEER)-Medicare data to identify men diagnosed with prostate cancer between 2001 and 2007 who underwent either 3D-CRT (n=6,976) or IMRT (n=11,039). Measurements We assessed our main outcomes (i.e., the adjusted use of salvage therapy with androgen deprivation therapy (ADT) and risk of a complication requiring an intervention) using Cox proportional-hazards models. Results and limitations The percentage of men receiving IMRT increased from 9% in 2001 to 93% in 2007. Compared to those treated with 3D-CRT, low-risk patients treated with IMRT had similar likelihoods of using salvage therapy with ADT and similar risks of having a complication requiring an intervention (all p>0.05). Conversely, a subset of higher-risk patients treated with IMRT who did not receive concurrent ADT were less likely to use salvage therapy (p=0.02), while maintaining similar complication rates. Since our cohort includes Medicare beneficiaries, our findings may not be generalizable to younger patients. Conclusions For a subset of higher-risk patients, IMRT appears to show a benefit in terms of reduced salvage therapy without an increase in complications. For other patients, the risks of salvage therapy and complications are comparable between the two modalities. PMID:22790288

    Summary Background Considering the high prevalence of dementia, it would be of great value to develop effective tools to improve cognitive function. We examined the effects of a human-type communication robot on cognitive function in elderly women living alone. Material/Methods In this study, 34 healthy elderly female volunteers living alone were randomized to living with either a communication robot or a control robot at home for 8 weeks. The shape, voice, and motion features of the communication robot resemble those of a 3-year-old boy, while the control robot was not designed to talk or nod. Before living with the robot and 4 and 8 weeks after living with the robot, experiments were conducted to evaluate a variety of cognitive functions as well as saliva cortisol, sleep, and subjective fatigue, motivation, and healing. Results The Mini-Mental State Examination score, judgement, and verbal memory function were improved after living with the communication robot; those functions were not altered with the control robot. In addition, the saliva cortisol level was decreased, nocturnal sleeping hours tended to increase, and difficulty in maintaining sleep tended to decrease with the communication robot, although alterations were not shown with the control. The proportions of the participants in whom effects on attenuation of fatigue, enhancement of motivation, and healing could be recognized were higher in the communication robot group relative to the control group. Conclusions This study demonstrates that living with a human-type communication robot may be effective for improving cognitive functions in elderly women living alone. PMID:22936190

    Effective communication and teamwork is essential for the delivery of high quality, safe patient care. Communication failures are an extremely common cause of inadvertent patient harm. The complexity of medical care, coupled with the inherent limitations of human performance, make it critically important that clinicians have standardised communication tools, create an environment in which individuals can speak up and express concerns, and share common "critical language" to alert team members to unsafe situations. All too frequently, effective communication is situation or personality dependent. Other high reliability domains, such as commercial aviation, have shown that the adoption of standardised tools and behaviours is a very effective strategy in enhancing teamwork and reducing risk. We describe our ongoing patient safety implementation using this approach within Kaiser Permanente, a non-profit American healthcare system providing care for 8.3 million patients. We describe specific clinical experience in the application of surgical briefings, properties of high reliability perinatal care, the value of critical event training and simulation, and benefits of a standardised communication process in the care of patients transferred from hospitals to skilled nursing facilities. Additionally, lessons learned as to effective techniques in achieving cultural change, evidence of improving the quality of the work environment, practice transfer strategies, critical success factors, and the evolving methods of demonstrating the benefit of such work are described.

    The ability of patients in many parts of the world to benefit from transplantation is limited by growing shortages of transplantable organs. The choice architecture of donation systems is said to play a pivotal role in explaining this gap. In this paper we examine the question how different defaults affect the decision to register as organ donor. Three defaults in organ donation systems are compared: mandated choice, presumed consent and explicit consent. Hypothetical choices from a national survey of 2069 respondents in May 2011 in the Netherlands - a country with an explicit consent system - suggests that mandated choice and presumed consent are more effective at generating registered donors than explicit consent.

    The aim of this study was to develop and evaluate a communication skills training programme for the management of dental anxiety. The aims of the training were directed at the enhancement of knowledge and communication skills. The research design consisted of a pre-test-post-test-control group design. The instruments were a knowledge test, a behavioural role-play test and a learner report. Thirty-four graduate students participated in the study. The results showed that the communication skills training had an effect on the knowledge and a substantial effect on the behaviour of the students. Moreover, the results from the learner report showed that the students acquired important insights in their own capacities and limitations. The conclusions are that the course as a whole is effective for dealing with anxious patients. Finally, it is recommended that knowledge and behaviour examinations are introduced as a regular part of the curricula for dentistry students. PMID:14739968

    The aim of this study was to examine the effectiveness of various types of parental communication in modifying children's responses to television food advertising. In a combined diary-survey study among 234 parents of 4- to 12-year-old children, I investigated how different styles of advertising mediation (active vs. restrictive) and consumer communication (concept-oriented vs. socio-oriented) moderated the relation between children's advertising exposure and their consumption of advertised energy-dense food products. Interaction analysis in regression showed that active advertising mediation (i.e. explaining the purpose and nature of advertising), and socio-oriented consumer communication (i.e. emphasizing control and restrictions) significantly reduced the impact of advertising on children's food consumption. Parental restrictions of advertising exposure were only effective among younger children (<8). These results suggest that critical discussion about advertising and rule making about consumption are most effective in countering the impact of food advertising. PMID:19972665

  20. The principle of parity: the 'placebo effect' and physician communication.

    The use of 'placebos' in clinical practice is a source of continued controversy for physicians and medical ethicists. There is rarely any extensive discussion on what 'placebos' are and how they work. In this paper, drawing on Louhiala and Puustinen's work, the author proposes that the term 'placebo effect' be replaced in clinical contexts with the term 'positive care effect'. Medical treatment always takes place in a 'context of care' that encompasses all the phenomena associated with medical intervention it includes the particular method of treatment, the interpersonal relationships between medical staff and the patient and other factors, including physicians' and patients' beliefs in the power of the treatment. Together, these phenomena can result in a full spectrum of therapeutic effects to the patient--from no effects, to small effects, to large effects. In cases where there are significant therapeutic benefits to the patient, 'positive care effects' may be spoken of. Since the ethical codes of the General Medical Council and the American Medical Association demand transparency with respect to patient treatment and insist on complete openness in 'placebo' usage, the author argues that, as a matter of conceptual rigour and consistency, if the term 'placebo effect' is replaced by 'positive care effect', these ethical codes appear to insist on transparency about all such beneficial components of treatment. Given that this appears to be a counterintuitive obligation, the author concludes the paper with some comments on the clinical consequences of this conceptual revision, including a brief discussion of how this important debate might develop.

    We examine the effect of different radiative transfer schemes on the properties of three-dimensional (3D) simulations of near-surface stellar convection in the superadiabatic layer, where energy transport transitions from fully convective to fully radiative. We employ two radiative transfer schemes that fundamentally differ in the way they cover the 3D domain. The first solver approximates domain coverage with moments, while the second solver samples the 3D domain with ray integrations. By comparing simulations that differ only in their respective radiative transfer methods, we are able to isolate the effect that radiative efficiency has on the structure of the superadiabatic layer. We find the simulations to be in good general agreement, but they show distinct differences in the thermal structure in the superadiabatic layer and atmosphere.

  2. Less is more? Think again! A cognitive fluency-based more-less asymmetry in comparative communication.

    Differences between groups, individuals, or objects can be framed in multiple ways. One can, for instance, say that men generally earn more than women or that women generally earn less than men. Showing that these logically equivalent expressions are not psychologically equivalent, we demonstrate a robust more-less asymmetry in the use of and responses to comparative statements. More specifically, we show that people use "more than" statements more often than "less than" statements (Study 1); like "more than" statements better (Studies 2 and 3), agree more with opinions expressed through "more than" statements (Studies 4 and 5), and are more likely to consider factual "more than" statements to be true (Study 6). Supporting a cognitive fluency explanation, a manipulation that makes people expect disfluency while processing "less than" statements reduces this otherwise robust more-less asymmetry (Study 7). By combining comparative framing effects with cognitive fluency, the present research brings together 2 research fields in social cognition, shedding new light on both. PMID:26167798

    Introduction. Future health care providers need to be trained in the knowledge and skills to effectively communicate with their patients with limited health literacy. The purpose of this study is to develop and evaluate a curriculum designed to increase residents' health literacy knowledge, improve communication skills, and work with an interpreter. Materials and Methods. Family Medicine residents (N = 25) participated in a health literacy training which included didactic lectures and an objective structured clinical examination (OSCE). Community promotoras acted as standardized patients and evaluated the residents' ability to measure their patients' health literacy, communicate effectively using the teach-back and Ask Me 3 methods, and appropriately use an interpreter. Pre- and postknowledge, attitudes, and postdidactic feedback were obtained. We compared OSCE scores from the group that received training (didactic group) and previous graduates. Residents reported the skills they used in practice three months later. Results. Family Medicine residents showed an increase in health literacy knowledge (p = 0.001) and scored in the adequately to expertly performed range in the OSCE. Residents reported using the teach-back method (77.8%) and a translator more effectively (77.8%) three months later. Conclusions. Our innovative health literacy OSCE can be replicated for medical learners at all levels of training. PMID:26491565

    The transition from paper to electronic-based records in the healthcare industry has posed several challenges to conventional medical practices. The introduction of technology in day-to-day medical and nursing practices deserves careful consideration. In this work, we report the results of a controlled experiment to compare nurses' consultation in emergency calls in six different conditions. We studied the effect that the type of communication media (face-to-face, telephone, videoconference) and type of nursing protocol media (paper-based, electronic-based) can have on consultation time, mistakes made, pauses during consultation, eye contact, and efficacy of the consultation. We found that the type of communication media has an effect on consultation time; on average, fewer mistakes were made during telephone-based consultations; for eye contact, there were significantly fewer eye contacts during face-to-face than during videoconference consultations; finally, the type of communication media or protocol media did not have any effect in the efficacy of the consultation.

    Abstract Background Due to low-birth-weight, preterm birth, HIV and/or AIDS and poverty-related factors, South Africa presents with an increased prevalence of infants at risk of language delay. A Kangaroo Mother Care (KMC) unit offers unique opportunities for training. Aim The aim of the present study was to determine if formal, neonatal communication-intervention training had an effect on mothers’ knowledge and communication interaction with their high-risk infants. Methods Three groups of mothers participated: Group 1 was trained whilst practicing KMC; Group 2 was not trained but practiced KMC; and Group 3 was also not trained but practiced sporadic KMC. Ten mothers per group were matched for age, education level and birth order of their infants. The individual training was based on graded sensory stimulation and responsive mother-infant communication interaction, which emphasised talking and singing by the mother. Results Significant differences were found in mother-infant communication interaction between all three groups, which indicated a positive effect on Group 1 with training. Group 2, KMC without training, also had a positive effect on interaction. However, Group 1 mothers with training demonstrated better knowledge of their infants and were more responsive during interaction than the other two groups. Conclusion The present study suggests that neonatal communication-intervention training adds value to a KMC programme. PMID:26245414

    The effectiveness of a behavioral skills training (BST) package to teach the implementation of the first three phases of the picture exchange communication system (PECS) was evaluated with 3 adults who had no history teaching any functional communication system. A multiple baseline design across participants was used to evaluate the effectiveness of the training package, which consisted of a video, written and verbal instructions, modeling, rehearsal, and feedback. Results showed significant improvements relative to baseline in a short amount of training time and that skills generalized to a learner with a severe developmental disability. Skills were maintained at 1 month follow-up for 1 participant. PMID:20190917

    2011-05-01

    In the context of health campaigns, interpersonal communication can serve at least 2 functions: (a) to stimulate change through social interaction and (b) in a secondary diffusion process, to further disseminate message content. In a 3-wave prospective study of 1,079 smokers, the authors demonstrate that mass media messages (antismoking campaigns and news coverage relevant to smoking cessation) have an indirect effect on smoking cessation intention and behavior via interpersonal communication. Exposure to campaigns and news coverage prompts discussion about the campaigns, and, in turn, about smoking cessation. Interpersonal communication regarding smoking cessation then influences intention to quit smoking and attempts to quit smoking. The study finds evidence not only for the social interaction function of interpersonal communication, but also for the secondary diffusion function. A substantial number of smokers who are not directly exposed to the antismoking campaigns are nevertheless indirectly exposed via communication with people who have seen these campaigns. These results imply that encouragement of interpersonal communication can be an important campaign objective. PMID:21337250

    The purpose of this study was to evaluate the effects of functional communication training (FCT) on the occurrence of non-targeted disruptive behavior. The 10 participants were preschool-aged children with developmental disabilities who engaged in both destructive (property destruction, aggression, self-injury) and disruptive (hand flapping, spinning in circles, shrill laughter, screaming, crying) behaviors. Only destructive behavior was targeted for the functional analyses and FCT, but data were also collected on disruptive behaviors. All procedures were conducted in the participants’ homes by their mothers with investigator coaching. Phase 1 consisted of conducting a functional analysis within a multielement design. Phase 2 consisted of conducting FCT with demand fading and repeated extinction baselines within a reversal design. Single-case data are provided for 3 participants, and summary data are provided for all 10 participants. Results of phase 1 showed that all participants’ destructive and disruptive behavior was maintained, at least in part, by negative reinforcement. Results of phase 2 showed that both destructive behavior and non-targeted disruptive behavior occurred at lower levels during FCT when compared to the functional analysis demand condition and baseline conditions, suggesting that FCT was effective in decreasing both target destructive behavior and non-targeted disruptive behaviors.

    Twenty patients randomly assigned to an experimental and a control group participated in a double blind study to assess the effectiveness of acupuncture in bronchial asthma, using the peak expiratory flow rate (PEFR) as an index of bronchial patency. All patients in the control group showed a significant improvement in their PEFR while only 3 patients in the treated group showed an improvement. A subjective improvement and a reduction in drug dosages were observed in both groups. It is concluded that acupuncture has a placebo effect in bronchial asthma. PMID:7040659

    This paper considers the effect of noise on conversation between two persons seated in a close, side-by-side position such as in a small aircraft. Twelve pairs of subjects were required to converse while being exposed to noises of various levels and spectra similar to those currently found in general aviation aircraft. After a period of noise exposure, subjects rated the disruptive effect of the noise on conversation and judged the acceptability of the noise. Subjective estimates of the maximum times for pleasant conversation in the noises were also obtained.

    We show how, under the influence of non-Markovian environments, two different maximally entangled Bell states give rise to states that have equal classical correlations and the same capacities to violate the Bell-Clauser-Horne-Shimony-Holt inequality, but intriguingly differing usefulness for teleportation and dense coding. We elucidate how different entanglement measures like negativity and concurrence, and two different measures of quantum discord, could account for these behaviors. In particular, we explicitly show how the Ollivier-Zurek measure of discord directly accounts for one state being a better resource for dense coding compared to another. Our study leads to several important issues about these measures of discord.

    Objective: At the University of Leipzig, the requirements of the Licensing Regulations for Doctors (Approbationsordnung für Ärzte) for the practical training of communication skills are actively implemented by a two-semester communication course. During this course, student tutors impart the basics of interpersonal as well as selected aspects of doctor-patient communication using interactive training methods. This article reports on the effect the training has on the self-assessed communication skills of the medicine students. Methods: The students’ self-perceived communication skills were assessed, both at the beginning and after the completion of the first and second course semesters using questionnaires related to the course’s learning goals. Pre-post comparisons were then carried out. 142 students (of 163 students in total) participated in the survey at the start of the course, of which 117 completed the T2-questionnaire at the end of the first course semester. Only the 84 students who also completed the questionnaires in the second course semester were included in the statistical analysis. These responses were analysed using both descriptive and inferential statistics. Results: The comparison of the self-assessments between the four measurement points showed that statistically significant learning progress for all assessed communication skills had taken place from the point of view of the students. The largest changes between measurements, and therefore the greatest learning progress, could be seen in knowledge related skills. Conclusion: From the students’ point of view the communication training contributes significantly to the acquisition of communication skills. The results suggest that this “hands-on” course concept is suited to successfully enhance the students’ communication skills. The course concept should therefore be retained for both the course in its current form as well as for any extension of the course into the clinical part of

    The data transmission in coherent fiber-optical communication lines using solitons with a variable phase is studied. It is shown that nonlinear coherent structures (solitons) can be applied for effective signal transmission over a long distance using amplitude and optical-phase keying of information. The optimum ratio of the pulse width to the bit slot at which the spectral efficiency (transmitted bits per second and hertz) is maximal is determined. It is shown that soliton fiber-optical communication lines can ensure data transmission at a higher spectral efficiency as compared to traditional communication lines and at a high signal-to-noise ratio.

    Work in the construction industry is considered inherently dangerous, despite the technological improvements regarding the safety of work conditions and equipment. To address the urgent need to identify organizational predictors of safety performance and outcomes among construction workers, the present study examined multi-level effects of two important indicators of safety climate, namely contractor error management climate and worker safety communication, on safety behavior, injury, and pain among union construction workers. Data were collected from 235 union construction workers employed by 15 contractors in Midwest and Northwest regions of the United States. Results revealed significant main effects for safety communication and error management climate on safety behaviors and pain, but not on injuries. Our findings suggest that positive safety communication and error management climate are important contributors to improving workplace safety. Specific implications of these results for organizational safety research and practice are discussed. PMID:20538106

  3. Comparative Effectiveness Research: A Cornerstone of Healthcare Reform?

    Mushlin, Alvin I.; Ghomrawi, Hassan M.K.

    2010-01-01

    Comparative Effectiveness Research (CER) has recently emerged as a major theme in health care reform. Unfortunately, there is a widespread lack of understanding about what it will do and fear that it will do more harm than good. These concerns include threats to individual physician's autonomy and professionalism, as well as fears that care will be rationed based on such findings. In this paper, we argue that the main components of the current healthcare reform (HCR) bills, which include expanding insurance while increasing efficiencies through cost containment, should embrace CER. This type of research will provide a “safeguard” against “blind” cost-containment, so that the new financial incentives being introduced can be actualized effectively and safely. Evidence for this is provided from examples from the authors' prior and current research as well as from the literature. We also argue that the requirement for data from CER will create long-term disincentives for “me-too” drugs and devices and, therefore, become a catalyst for effective innovation. PMID:20697557

    2016-06-01

    Comparative effectiveness research (CER) enables the comparison of different treatments in the real-world setting to inform clinical decision-making. Rheumatoid arthritis (RA) has been identified as a high priority area for CER. Administrative health databases, which generally consist of physician billing claims, hospital discharge summaries and prescription drug records, have been widely used to conduct observational research in RA. These data are accurate and complete records of health-care use unaffected by recall bias, and provide large, general population samples and information on long-term follow-up. However, administrative health data pose unique methodological challenges for CER in the field of RA. Here, we discuss the challenges of studying treatment effectiveness with CER (as distinct from harms and costs), in particular, issues relating to the identification and definition of RA cases, timing of disease onset and determination of disease severity. We also discuss an algorithm developed to measure effectiveness outcomes of RA treatments in administrative data, and potential sources of bias that might affect the validity of results. Finally, we explore opportunities for use of administrative data in CER, such as comparisons between reference drugs and biosimilars. PMID:27080692

    1994-02-01

    The effects of ultraviolet (UV) radiation on gap junctional intercellular communication (GJIC) in V79 Chinese hamster fibroblasts were studied by means of a dye transfer assay. Intercellular communication was shown to be altered by UVB (297/302 nm) and UVA (365 nm) radiation, the effect depending on the wavelength of exposure and time between irradiation and microinjection of the dye in the dye transfer assay. Exposure to 297/302 nm radiation induced a reduction in intercellular communication 6 min after exposure. Incubation of the cells post-irradiation reversed the inhibition of GJIC. From 2 to 24 h after exposure an increase in GJIC over the control cells was seen, with a maximum at 8 h post-irradiation. UVA (365 nm) radiation, on the other hand, induced an increase in the intercellular communication 6 min after irradiation. Incubation of the cells post-irradiation led to a decrease in the number of communicating cells, with a minimum seen 4 h after exposure. The reduction in communication observed after exposure to UVB and UVA was not correlated with similar modifications in the gap junction protein connexin43 as found when exposing the cells to the tumour promoter 12-O-tetradecanoyl-phorbol-13-acetate. For the higher fluences of UVA, a decrease in immunorecognizable connexin43 was seen, concomitant with a markedly increased background of higher mol. wt compounds. This may be due to UVA-induced crosslinking of connexin43. No correlation was found between changes in communication induced by UV radiation and levels of cyclic AMP. PMID:8313514

    The purpose of this study is to show the effect of hydrostatic pressure on the electrical ageing, by a dc voltage, on polyethylene used in submarine cables. Experimental results are obtained at 1 and 300 bar, for a temperature of 70 °C in the range of an electrical field of 1.1-4.5 MV cm-1 and for up to 1500 h of ageing. By using the Weibull statistic and the estimation of confidence bounds of 90%, the results have shown an increase of lifetime with pressure. The time dependence of the breakdown behaviour of the two materials (HDPE and XLPE) is consistent with the inverse power law model. The pressure effect may be explained by changes in the activation free energy for the formation of submicrocavities.

    This paper presents a study of the performance of federated queries implemented in a system that simulates the architecture proposed for the Scalable Architecture for Federated Translational Inquiries Network (SAFTINet). Performance tests were conducted using both physical hardware and virtual machines within the test laboratory of the Center for High Performance Computing at the University of Utah. Tests were performed on SAFTINet networks ranging from 4 to 32 nodes with databases containing synthetic data for several million patients. The results show that the caGrid FQE (Federated Query Engine) is capable and suitable for comparative effectiveness research (CER) federated queries given its nearly linear scalability as partner nodes increase in number. The results presented here are also important for the specification of the hardware required to run a CER grid. PMID:22941983

    With the increasing availability of therapeutic strategies (drugs, devices, disease management systems) and the growing complexity of health care delivery, there is an attendant need for objective evidence of the tangible benefits of different approaches to care. This is particularly true for patients with heart failure, a common, morbid, and resource-intensive disease. There are few well-proven therapies for patients with acute decompensation or for patients with normal LVEF. Comparative effectiveness research (CER) offers an important avenue for making progress in the field. However, CER, like any well-designed research program, requires the explicit articulation of clinically important outcomes to be compared. For patients with heart failure, there is a need to develop endpoint measures that capture the totality of potential benefits and risks for alternative therapeutic approaches. Ultimately, for one therapeutic approach to be considered superior to another, it must improve one of three relevant endpoints: make patients live longer, make them feel better, or save money without adversely affecting the other two goals. Importantly, these outcomes must be measured directly and surrogates should be avoided, even if such surrogates appear to be associated with clinically meaningful, patient-centered outcomes. In this review, we discuss the available CER endpoint domains from both a clinical and a statistical perspective, summarize the wide variety of endpoints used in CER studies, and suggest steps for greater standardization of endpoints across CER studies of patients with heart failure.

    The recent growth of research in message tailoring has opened up new avenues for researchers to use personality variables for message delivery. This article builds on research on idiocentrism and self-monitoring to propose a framework for message appeal construction. Based on a scheme for appeal categorization borrowed from commercial marketing, the article suggests that low and high idiocentrics differ from each other in the way they respond to appeal types. Similarly, significant differences are demonstrated between low and high self-monitors in the realm of their response to message appeals. A linear interaction model is proposed to document the combined effects of self-monitoring and idiocentrism. PMID:12553779

Results generally suggest that the benefits depend on how a patient uses the system, far more than on sheer amount of exposure or even what type of content is chosen. The next generation of eHealth system should focus on providing new and varying content over time, but even more on encouraging intensity of use and long-term commitment to the system. PMID:23172985

    Information technology (IT) has produced a deep impact on human lives, and the most important aspect of its effect is on education and learning. This study was done for the purpose of evaluating the effectiveness of electronic health information on our Web site http://www.teen.hbi.ir in the promotion of health education and in increasing the capabilities of the students in the use of the Internet. This study was performed on the basis of the information obtained from the questionnaires on selected health issues from 649 students from 3 high schools. Information was collected in 2 steps (pretest and posttest). The t test and Leven's test were used in the statistical analysis of data. Results of the t test showed that educating students through health information Web sites has increased their knowledge by at least 14.5% on environmental health and 48.9% on nutrition and was statistically meaningful in all fields (P=.000) with the exception of mental health. The fact is that the use of IT has become a part of our society and is perhaps the most promising medium for achieving health promotion initiatives. PMID:19625324

  14. Communication: Isotopic effects on tunneling motions in the water trimer

    NASA Astrophysics Data System (ADS)

    Videla, Pablo E.; Rossky, Peter J.; Laria, D.

    2016-02-01

    We present results of ring polymer molecular dynamics simulations that shed light on the effects of nuclear quantum fluctuations on tunneling motions in cyclic [H2O]3 and [D2O]3, at the representative temperature of T = 75 K. In particular, we focus attention on free energies associated with two key isomerization processes: The first one corresponds to flipping transitions of dangling OH bonds, between up and down positions with respect to the O-O-O plane of the cluster; the second involves the interchange between connecting and dangling hydrogen bond character of the H-atoms in a tagged water molecule. Zero point energy and tunneling effects lead to sensible reductions of the free energy barriers. Due to the lighter nature of the H nuclei, these modifications are more marked in [H2O]3 than in [D2O]3. Estimates of the characteristic time scales describing the flipping transitions are consistent with those predicted based on standard transition-state-approximation arguments.

  15. Effects of ocean thermocline variability on noncoherent underwater acoustic communications.

    2007-04-01

    The performance of acoustic modems in the ocean is strongly affected by the ocean environment. A storm can drive up the ambient noise levels, eliminate a thermocline by wind mixing, and whip up violent waves and thereby break up the acoustic mirror formed by the ocean surface. The combined effects of these and other processes on modem performance are not well understood. The authors have been conducting experiments to study these environmental effects on various modulation schemes. Here the focus is on the role of the thermocline on a widely used modulation scheme (frequency-shift keying). Using data from a recent experiment conducted in 100-m-deep water off the coast of Kauai, HI, frequency-shift-key modulation performance is shown to be strongly affected by diurnal cycles in the thermocline. There is dramatic variation in performance (measured by bit error rates) between receivers in the surface duct and receivers in the thermocline. To interpret the performance variations in a quantitative way, a precise metric is introduced based on a signal-to-interference-noise ratio that encompasses both the ambient noise and intersymbol interference. Further, it will be shown that differences in the fading statistics for receivers in and out of the thermocline explain the differences in modem performance. PMID:17471705

  17. Assessing the Use of Metaphors to Facilitate and Improve the Effectiveness of Climate Change Communication

    NASA Astrophysics Data System (ADS)

    Walsh-Thomas, J.; Maibach, E.

    2014-12-01

    Metaphors are sometimes used in science communication to explain unfamiliar scientific concepts and processes in more familiar terms. Empirical research has shown that metaphors can help audiences better understand complicated scientific concepts. A growing number of metaphors are used to explain various climate science concepts, but the only empirical evaluation of climate metaphors to date (van der Linden et al, 2014, Climatic Change) found that medical and bridge safety metaphors did not enhance the effectiveness of a simple corrective statement about the scientific consensus on human-caused climate change. Drawing on a recent meta-analysis by Sopory and Dillard (2002, Hum Commun. Res.), we will briefly review what is known about appropriate metaphor usage in communicating scientific concepts. We will also present preliminary findings from an experiment currently underway to further explain the conditions in which metaphors are likely to help in communicating climate science concepts. We hypothesize that metaphors will be more effective in communicating high complexity climate science concepts that are less easily understood by the public than more easily understood low complexity concepts (such as scientific consensus on climate change). We also hypothesize that the more familiar people are with the referent (performance enhancing drugs in baseball is a metaphor about "the climate system on steroids"), the more effective the metaphor will be. To test these hypotheses, we are randomly assigning ~1000 adults - approximately representative of the US adult population - to read one brief passage in which one of four relatively simple or complex climate concepts is presented and explained with or without a metaphor. The outcome measures will include climate change belief, concern, knowledge, and involvement. This study is intended to add to the knowledge base about use of metaphors in science communication, and provide practical advice to climate communicators.

  4. Novel Therapeutics for Diabetes: Uptake, Usage Trends, and Comparative Effectiveness.

    PubMed

    Ahuja, Vishal; Chou, Chia-Hung

    2016-06-01

    The number of available therapies for treating type 2 diabetes has grown considerably in recent years. This growth has been fueled by availability of newer medications, whose benefits and risks have not been fully established. In this study, we review and synthesize the existing literature on the uptake, efficacy, safety, and cost-effectiveness of novel antidiabetic agents. Specifically, we focus on three drug classes that were introduced in the market recently: thiazolidinediones (TZDs), dipeptidyl peptidase-4 (DPP-4) inhibitors, and glucagon-like peptide-1 (GLP-1) receptor agonists. Not surprisingly, we find that the usage trends reflect the efficacy and safety profile of these novel drugs. The use of TZDs increased initially but decreased after a black-box warning was issued for rosiglitazone in 2007 that highlighted the cardiovascular risks associated with using the drug. Conversely, DPP-4 inhibitors and GLP-1 receptor agonists gained market shares due to their efficacy in glycemic control as an add-on treatment to metformin. DPP-4 inhibitors were the most commonly prescribed agents among the three novel drug classes, likely because they are relatively less expensive, have better safety profile, are administered orally, and are weight neutral. Sitagliptin was the most preferred DPP-4 inhibitor. The level of evidence on the comparative effectiveness, safety, and cost implications of using novel antidiabetic agents remains low and further studies with long-term follow-ups are needed.

  5. Translating comparative effectiveness research into clinical practice: the UK experience.

    PubMed

    Walley, Tom

    2012-01-22

    Comparative effectiveness research (CER) is not new but its potential to improve the effectiveness of healthcare has not yet been exploited in the US. Other countries such as the UK have more experience of this. Key points of the UK experience are summarized here and some possible pointers for the US are drawn. These include the following: how to go beyond the evidence and apply judgements to make recommendations with authority and in a timely manner; how to implement these recommendations; how to identify suitable topics; and how to be open and transparently fair to all stakeholders. The quality of the science of CER is key but this needs developing, and not just in biomedical or statistical terms but also in how to understand public expectations, and how to implement its recommendations. A key issue is the role of health economics, which seems to have been marginalized by the CER legislation, but perhaps this is more apparent than real. Clearly this is a matter for much further debate. It is hard to see how CER can deliver its potential without active consideration of both benefits and costs. Although other countries have more experience of this than does the US, the context for such work is always very specific and the US will have to find its own way, while trying to avoid some of the errors made elsewhere.

    2016-07-01

    Communicating non-urgent, urgent and frank emergency requests for assistance between anaesthetists in theatre often requires a 'go-between' - frequently a non-anaesthetic healthcare professional - to transmit information. We compared the currently recommended situation, background, assessment, recommendation (SBAR) tool with a newly devised Traffic Lights tool ('red alert', 'amber assist' and 'green query') in a simulation study to assess communication quality using 12 validated clinical scenarios of varying urgency. Compared to SBAR, Traffic Lights was used more consistently ('very clear' or 'clear' Traffic Lights 94% vs SBAR 69%); transferred information better (two or three pieces of information correctly transferred Traffic Lights 85%, SBAR 44%; and was judged to lead to greater clarity (all p < 0.0001). Message delivery time was significantly reduced (Traffic Lights 20.5 s vs SBAR 45.5 s, median (95% CI) difference 25 (19-30) s, p < 0.001). Users rated the Traffic Lights system as significantly more useful than SBAR, with 96% of participants preferring the Traffic Lights tool. Results were independent of go-between training. We recommend the adoption of this communication tool as standard practice for anaesthetic teams. PMID:27080525

  7. Effect of Small Transmission Delay on Human Behavior in Audio Communication

    Ohnishi, Hitoshi; Mochizuki, Kaname

    Transmission delay in audio communications is a well-known obstacle to achieving smooth communication. However, it is not known what kinds of effects are caused by small delays. We hypothesized that the small delay in the listener's responses disturbs the speaker's “verbal conditioning, ” where the verbal behavior of the speaker varies in accordance with the listener's responses. We examined whether the small delays in the listener's responses disturb the speaker's verbal conditioning using an artificial-grammar learning task. The results suggested that a 300-ms delay disturbed the participants' verbal conditioning although they were not adequately aware of the delay.

    1982-10-01

    The technique of esophageal scintigraphy was developed as a sensitive, quantitative, noninvasive test of esophageal transit. Esophageal scintigraphy was performed in 40 asymptomatic normal volunteers in order to determine the effect on esophageal transit of the following: body posture (sitting vs. supine), liquid vs. solid, the solid being either a standard number4 gelatin capsule of the size used for antibiotic capsules, or a cube of solid food such as cooked chicken liver. The results showed that liquids emptied completely from the esophagus after one swallow, whether supine or sitting. Capsules or liver cubes, when ingested without water, frequently remained in the esophagus for up to two hours without the subject's having any sensation that the solid had not left the esophagus. Both capsules and liver cubes cleared the esophagus better in the upright than in the supine position. When gelatin capsules were swallowed with as little as 15 ml of water, but after a preliminary sip of water, there was complete transit in each case. The study suggests that the practice of assisting patients into a sitting position and instructing them to take a sip of water before attempting to swallow a capsule will assure better transit of the capsule even when swallowed with as little as 15 ml of water. This may reduce the incidence of esophagitis following oral antibiotics, and of esophageal erosions from aspirin-containing medications.

    2014-05-01

    The rapid increase of social media and online newspapers in the last years have given the opportunity to make a national investigation on macroseismic effects on the Maltese Islands based on felt earthquake reports. A magnitude 4.1 earthquake struck close to Malta on Sunday 24th April 2011 at 13:02 GMT. The earthquake was preceded and followed by a series of smaller magnitude quakes throughout the day, most of which were felt by the locals on the island. The continuous news media coverage during the day and the extensive sharing of the news item on social media resulted in a strong public response to fill in the 'Did you feel it?' online form on the website of the Seismic Monitoring and Research Unit (SMRU) at the University of Malta (http://seismic.research.um.edu.mt/). The results yield interesting information about the demographics of the island, and the different felt experiences possibly relating to geological settings and diverse structural and age-classified buildings. Based on this case study, the SMRU is in the process of developing a mobile phone application dedicated to share earthquake information to the local community. The application will automatically prompt users to fill in a simplified 'Did you feel it?' report to potentially felt earthquakes. Automatic location using Global Positioning Systems can be incorporated to provide a 'real time' intensity map that can be used by the Civil Protection Department.

    We report the effect of interferences on visible light car-to-car communication system. The interferences from floor reflections and fluorescent lamps are taken into account for indoor car-to-car visible light communication (VLC) systems. The system is composed of a white LED lamp as a VLC transmitter and a photo-receiver with an appropriate optical filter as a VLC receiver. The signal power distribution patterns are measured and analyzed at a transmission distance, considering the positions of the transmitter and receiver. Generally, the light from fluorescent lamps in indoor environment affects the DC level of the received signal power, which is more significant at higher receiver positions. The measurements show that the indoor VLC communication performance can be varied depending on floor reflections. Also, the fluorescent ceiling illuminations affect the DC level change of the received VLC signal waveforms.

    2015-11-01

    The high rates of sexual risk behaviors, particularly among African American youths who may not be aware of their HIV status, provide indication that, unless prevention efforts are enhanced, this vulnerable group of youths will remain at greater risk for negative health status outcomes. Parents are important in efforts to reduce risk among youths and often have a willingness to be sexuality educators for their children; however, communication barriers often impede their ability to provide preventive sexual health knowledge to their youths. Social workers are often presented with opportunities to help parents develop effective sexual health communication skills in informal settings when formal interventions are not feasible. The present effort considers solution-focused strategies social workers can use to help parents overcome barriers and communicate more positively with their youths about sexual health. PMID:26638502

    Introduction effective communication in a clinical environment plays a vital role in patient assessment and treatment. The aim of this study was to understand the experiences of Malaysian medical students concerning communication barriers during clinical practice. The goal was to provide answers for three important research questions, i.e., 1) Are communication barriers an impediment to Malaysian students during clinical teaching? 2) What is the nature of the language barriers that the students encounter? and 3) What are the best ways of reducing these barriers during clinical teaching? Methods The qualitative method was used to conduct the research, and open-ended questionnaires were used to collect the data. The study was conducted on 95 fourth-, fifth-, and sixth-year students, 80% of whom completed the study. Results Medical students from Malaysia who have limited knowledge of the Arabic language experience some difficulties in communicating with staff members, patients, and nurses during their clinical practices. Conclusion Successful orientation of students to the language used in the clinical environment will help the students overcome the communication barriers they encounter during their clinical practices.

    This paper examines problems of assessment and decision-making that result from poor or inadequate communication of indicators among the disciplines of public health, the physical sciences, and economics. The specific examples used are drawn from climate impacts in the Americas although the issues are more general to environmental health. In terms of physical processes, problems arise in confusion about indicators at different steps along the DPSEEA framework of environmental health indicators and general scientific uncertainty about the underlying physical processes. Communication between public health and economics is hindered by a lack of understanding of economic costs used in making decisions and the presence of implicit value judgments in economic analysis. Organizational structures may further inhibit the effective use of indicators. Finally, the paper discusses the Pan American Health Organization proposal to enhance the communication of indicators by using information technology networking to support communication among program managers and decision-makers at the national and local levels. The aim of this initiative is to establish a better environment for making decisions. The problem of cholera in Peru is shown as an example of the need for better communication. PMID:12425171

    The objective of this article is to discuss effective communication strategies between elderly patients and their physicians from the perspective of osteopathic heritage. The patient-physician communication styles of Andrew Taylor Still, MD, DO, and early osteopathic physicians (ie, DOs) may have influenced how DOs today communicate with their patients. Historical literature describes how Still would discuss with his patients the causes of their health problems using analogies and language they would understand, and how, when caring for a patient at the end of life, he empathically provided emotional support for both patients and their families. Early DOs advocated setting clear expectations for patients regarding clinical outcomes and carefully listening to patients to build trust. The Osteopathic Oath, which calls for the DO to view the patient as a friend, may also affect patient-physician communication. Early osteopathic philosophy and culture, as modeled by Dr Still in his approach to elderly patients, should inspire today's DOs in their communication with their elderly patients. PMID:26745563

    The communication signals of electric fish can be dynamic, varying between the sexes on a circadian rhythm and in response to social and environmental cues. In the gymnotiform fish Brachyhypopomus gauderio waveform shape of the electric organ discharge (EOD) is regulated by steroid and peptide hormones. Furthermore, EOD amplitude and duration change on different timescales and in response to different social stimuli, suggesting that they are regulated by different mechanisms. Little is known about how androgen and peptide hormone systems interact to regulate signal waveform. We investigated the relationship between the androgens testosterone (T) and 11-ketotestosterone (11-KT), the melanocortin peptide hormone α-MSH, and their roles in regulating EOD waveform of male B. gauderio. Males were implanted with androgen (T, 11-KT, or blank), and injected with α-MSH before and at the peak of androgen effect. We compared the effects of androgen implants and social interactions by giving males a size-matched male stimulus with which they could interact electrically. Social stimuli and both androgens increased EOD duration, but only social stimuli and 11-KT elevated amplitude. However, no androgen enhanced EOD amplitude to the extent of a social stimulus, suggesting that a yet unidentified hormonal pathway regulates this signal parameter. Additionally, both androgens increased response of EOD duration to α-MSH, but only 11-KT increased response of EOD amplitude to α-MSH. Social stimuli had no effect on EOD response to α-MSH. The finding that EOD amplitude is preferentially regulated by 11-KT in B. gauderio may provide the basis for independent control of amplitude and duration. PMID:21596047

    Reliable signaling information transfer is fundamental in supporting the needs of data communication PCS via LMS (Land Mobile Service) SSs (satellite systems). The needs of the system designer can be satisfied only through the collection of media information that can be brought to bear on the pertinent design issues. We at ISI hope to continue our dialogue with fading media experts to address the unique data communications needs of PCS via LMS SSs.

    Within the evolutionary framework about the origin of human handedness and hemispheric specialization for language, the question of expression of population-level manual biases in nonhuman primates and their potential continuities with humans remains controversial. Nevertheless, there is a growing body of evidence showing consistent population-level handedness particularly for complex manual behaviors in both monkeys and apes. In the present article, within a large comparative approach among primates, we will review our contribution to the field and the handedness literature related to two particular sophisticated manual behaviors regarding their potential and specific implications for the origins of hemispheric specialization in humans: bimanual coordinated actions and gestural communication. Whereas bimanual coordinated actions seem to elicit predominance of left-handedness in arboreal primates and of right-handedness in terrestrial primates, all handedness studies that have investigated gestural communication in several primate species have reported stronger degree of population-level right-handedness compared to noncommunicative actions. Communicative gestures and bimanual actions seem to affect differently manual asymmetries in both human and nonhuman primates and to be related to different lateralized brain substrates. We will discuss (1) how the data of hand preferences for bimanual coordinated actions highlight the role of ecological factors in the evolution of handedness and provide additional support the postural origin theory of handedness proposed by MacNeilage [MacNeilage [2007]. Present status of the postural origins theory. In W. D. Hopkins (Ed.), The evolution of hemispheric specialization in primates (pp. 59-91). London: Elsevier/Academic Press] and (2) the hypothesis that the emergence of gestural communication might have affected lateralization in our ancestor and may constitute the precursors of the hemispheric specialization for language.

    Objective To assess the effectiveness of glatiramer acetate (GA) compared to other multiple sclerosis (MS) therapies in routine clinical practice. Materials and methods Observational cohort study carried out in MS patients treated with GA (GA cohort) or other MS therapies –switched from GA– (non-GA cohort). Study data were obtained through review of our MS patient database. The primary endpoint was the Expanded Disability Status Scale (EDSS) scores reached at the end of treatment/last check-up. Results A total of 180 patients were included: GA cohort n = 120, non-GA cohort n = 60. Patients in the GA cohort showed better EDSS scores at the end of treatment/last check-up (mean ± SD, 2.8 ± 1.8 vs. 3.9 ± 2.2; P = 0.001) and were 1.65 times more likely to show better EDSS scores compared to the non-GA cohort (odds ratio, 0.606; 95%CI, 0.436–0.843; P = 0.003). Patients in the GA cohort showed longer mean time to reach EDSS scores of 6 (209.1 [95%CI, 187.6–230.6] vs. 164.3 [95%CI, 137.0–191.6] months; P = 0.004) and slower disability progression (hazard ratio, 0.415 [95%CI, 0.286–0.603]; P < 0.001). The annualized relapse rate was lower in the GA cohort (mean ± SD, 0.5 ± 0.5 vs. 0.8 ± 0.5; P = 0.001) and patients’ quality of life was improved in this study cohort compared to the non-GA cohort (mean ± SD, 0.7 ± 0.1 vs. 0.6 ± 0.2; P = 0.01). Conclusions GA may slow down the progression of EDSS scores to a greater extent than other MS therapies, as well as achieving a greater reduction in relapses and a greater improvement in patients’ quality of life. Switching from GA to other MS therapies has not proved to entail a better response to treatment. PMID:26085963
