  2. Congress should clarify the circumstances under which drug makers can communicate results on comparative effectiveness.

    PubMed

    Klasmeier, Coleen

    2012-10-01

    Hypothetical comparative effectiveness studies of two migraine drugs offer an opportunity to analyze the legal issues that manufacturers face in conveying to practicing physicians information from such research about prescription drugs. This information, derived from observational studies, supposedly cannot be communicated to clinicians because it does not constitute "substantial evidence" as required by law. In fact, however, the emerging effectiveness data can be included in manufacturers' communications to physicians about drugs' clinical utility through various existing channels defined by other law. This article argues that Congress should further clarify the circumstances under which such communications can occur to comply with First Amendment requirements that speech constraints be narrowly drawn, known in advance, and precise. Otherwise, the Food and Drug Administration risks losing First Amendment arguments in cases involving the agency's regulation of the communications-or "speech"-of drug manufacturers.

  4. Communication: comparing ab initio methods of obtaining effective U parameters for closed-shell materials.

    2014-03-28

    The density functional theory (DFT)+U method is an efficient and effective way to calculate the ground-state properties of strongly correlated transition metal compounds, with the effective U parameters typically determined empirically. Two ab initio methods have been developed to compute the U parameter based on either constrained DFT (CDFT) or unrestricted Hartree-Fock (UHF) theory. Previous studies have demonstrated the success of both methods in typical open-shell materials such as FeO and NiO. In this Communication we report numerical instability issues that arise for the CDFT method when applied to closed-shell transition metals, by using ZnO and Cu2O as examples. By contrast, the UHF method behaves much more robustly for both closed- and open-shell materials, making it more suitable for treating closed-shell transition metals, as well as main group elements.

  5. Comparative cost-effectiveness of the components of a behavior change communication campaign on HIV/AIDS in North India.

    2006-01-01

    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.

    1982-04-01

    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 Tc-99m, 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. Wheras 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 depresses 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.

    PubMed

    Ando, J

    1992-01-01

    The present study compared two different types of English-language teaching approaches, the grammatical approach (GA) and the communicative approach (CA), by the cotwin control method. This study has two purposes: to study the effects of teaching approaches and to estimate genetic influences upon learning aptitudes. Seven pairs of identical twins (MZ) and 4 pairs of fraternal twins (DZ) participated in the experiment along with 68 other nontwin fifth graders. Each cotwin was assigned to the GA and CA respectively and received 20 hours of lessons over a 10-day period. The behavioral similarities between MZ cotwins were statistically and descriptively depicted. No major effect of either teaching approach was noted, but the genetic influence upon individual differences of learning achievement was obvious. Furthermore, an interesting interaction between the teaching approaches and intelligence was found, that is, that the GA capitalises on and CA compensates for intelligence. This interactional pattern could be interpreted as an example of genotype-environment interaction. The relationship between genetic factors and learning aptitudes is discussed.

  18. 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

  1. Comparative analysis of nonverbal interpersonal communication of schizophrenics and normals.

    PubMed

    Hardin, S B

    1980-06-01

    The nonverbal communications of schizophrenics and normals in dyadic interactions were analyzed and compared. Twelve purposively selected women were videotaped in normal-normal, normal-schizophrenic, and schizophrenic-schizophrenic communication acts for 30 minutes. Using a PLATO IV computer program and a modified Kendon Kinesic Notation System, a priori sets of nonverbal behaviors were recorded at 1-second intervals. Frequency and duration scores for the sets of nonverbal behaviors with corresponding communication meanings were totaled. A nested analysis of variance showed that the three groups differed significantly (p less than .05) in engagement and defensiveness and that the normal interactors were the least imitative of the three groups. An analysis and description of the patterns of nonverbal communication also revealed differences, lending support to the theory of dysjunctive schizophrenic communication.

    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

  6. Space weather effects on communications

    NASA Astrophysics Data System (ADS)

    Lanzerotti, Louis J.

    In the 150 years since the advent of the first electrical communication system - the electrical telegraph - the diversity of communications technologies that are embedded within space-affected environments have vastly increased. The increasing sophistication of these communications technologies, and how their installation and operations may relate to the environments in which they are embedded, requires ever more sophisticated understanding of natural physical phenomena. At the same time, the business environment for most present-day communications technologies that are affected by space phenomena is very dynamic. The commercial and national security deployment and use of these technologies do not wait for optimum knowledge of possible environmental effects to be acquired before new technological embodiments are created, implemented, and marketed. Indeed, those companies that might foolishly seek perfectionist understanding of natural effects can be left behind by the marketplace. A well-considered balance is needed between seeking ever deeper understanding of physical phenomena and implementing `engineering' solutions to current crises. The research community must try to understand, and operate in, this dynamic environment.

    Star Cartier, Kimberly Michelle; Wright, Jason

    2017-01-01

    A fundamental aspect of our jobs as scientists is communicating our work to others. In this, the field of astronomy holds the double-edged sword of ubiquitous fascination: the topic has been of interest to nearly the entire global population at some point in their lives, yet the learning curve is steep within any subfield and rife with difficult-to-synthesize details. Compounding this issue is the ever-expanding array of methods to reach people in today's Communications Era. Each communication medium has its own strengths and weaknesses, is appropriate in different situations, and requires its own specific skillset in order to maximize its functionality. Despite this, little attention is given to training astronomers in effective communication techniques, often relying on newcomers to simply pick up the ability by mimicking others and assuming that a firm grasp on the subject matter will make up for deficiencies in communication theory. This can restrict astronomers to a narrow set of communication methods, harming both the communicators and the audience who may struggle to access the information through those media.Whether writing a research paper to academic peers or giving an astronomy talk to a pubic audience, successfully communicating a scientific message requires more than just an expert grasp on the topic. A communicator must understand the makeup and prior knowledge of the desired audience, be able to break down the salient points of the topic into pieces that audience can digest, select and maximize upon a medium to deliver the message, and frame the message in a way that hooks the audience and compels further interest. In this work we synthesize the requirements of effective astronomy communication into a few key questions that every communicator needs to answer. We then discuss some of the most common media currently used to communicate astronomy, give both effective and poor examples of utilizing these media to communicate astronomy, and provide key

    2015-02-01

    The ability to communicate with others is one of the most important human social functions, yet communication is not always investigated from a social perspective. This research examined the role that shared social identity plays in communication effectiveness using a minimal group paradigm. In two experiments, participants constructed a model using instructions that were said to be created by an ingroup or an outgroup member. Participants made models of objectively better quality when working from communications ostensibly created by an ingroup member (Experiments 1 and 2). However, this effect was attenuated when participants were made aware of a shared superordinate identity that included both the ingroup and the outgroup (Experiment 2). These findings point to the importance of shared social identity for effective communication and provide novel insights into the social psychology of communication.

    2015-01-01

    This paper describes a series of three randomized controlled case studies comparing the effectiveness of three strategies for communicating new research-based knowledge (Diffusion, Dissemination, Translation), to different Assistive Technology (AT) stakeholder groups. Pre and post intervention measures for level of knowledge use (unaware, aware, interested, using) via the LOKUS instrument, assessed the relative effectiveness of the three strategies. The latter two approaches were both more effective than diffusion but also equally effective. The results question the value added by tailoring research findings to specific audiences, and instead supports the critical yet neglected role for relevance in determining knowledge use by stakeholders.

    Oller, D Kimbrough; Griebel, Ulrike

    2014-09-01

    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.

Finally, we delineate two examples of infrastructural communicative capabilities that should be particularly amenable to direct quantitative comparison across humans and our closest relatives.

  6. Increasing pandemic vaccination rates with effective communication.

    PubMed

    Henrich, Natalie J

    2011-06-01

    Communicating effectively with the public about the importance of vaccination during a pandemic poses a challenge to health communicators. The public's concerns about the safety, effectiveness and necessity of vaccines lead many people to refuse vaccination and the current communication strategies are often unsuccessful at overcoming the public's resistance to vaccinate. Convincing the public to receive a vaccination, especially during a pandemic when there can be so much uncertainty about the vaccine and the disease, requires a revised communication approach. This revised approach should integrate into messages information that the public identifies as important, as well as presenting messages in a way that is consistent with our evolved social learning biases. These biases will impact both the content of the message and who delivers the message to different target populations. Additionally, an improved understanding between media and health communicators about the role each plays during a crisis may increase the effectiveness of messages disseminated to the public. Lastly, given that the public is increasingly seeking health information from on-line and other electronic sources, health communication needs to continue to find ways to integrate new technologies into communication strategies.

  7. Effective Perioperative Communication to Enhance Patient Care.

    PubMed

    Garrett, J Hudson

    2016-08-01

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

    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.

    Purpose Educating nursing home (NH) staff to provide person-centered care is complicated by scheduling, costs, and other feasibility issues. This study compared outcomes for an in-service program focused on person-centered communication provided in onsite and online formats. Methods The Changing Talk program was provided onsite in 7 NHs (327 staff). The online program included 8 NHs (211 staff). Outcomes were compared between groups. Results ANOVA revealed an interaction between format type and pre/post-test scores with improved recognition of person-centered communication in the onsite group only. Group program evaluations based on the modified Diffusion of Innovation in Long Term Care Battery indicated no significant differences between training formats. Conclusions Staff’s perception of the program was similar; and statistically significant gains in post-test scores indicating for awareness of person-centered communication for the onsite group have limited clinical significance. Feasibility and effectiveness are important considerations for in-service education supporting NH culture change. PMID:26046364

  3. 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

    Thomas, Joyce; McDonagh, Deana

    2013-01-01

    The ability to communicate to others and express ourselves is a basic human need. As we develop our understanding of the world, based on our upbringing, education and so on, our perspective and the way we communicate can differ from those around us. Engaging and interacting with others is a critical part of healthy living. It is the responsibility of the individual to ensure that they are understood in the way they intended.Shared language refers to people developing understanding amongst themselves based on language (e.g. spoken, text) to help them communicate more effectively. The key to understanding language is to first notice and be mindful of your language. Developing a shared language is an ongoing process that requires intention and time, which results in better understanding.Shared language is critical to collaboration, and collaboration is critical to business and education. With whom and how many people do you connect? Your 'shared language' makes a difference in the world. So, how do we successfully do this? This paper shares several strategies.Your sphere of influence will carry forward what and how you are communicating. Developing and nurturing a shared language is an essential element to enhance communication and collaboration whether it is simply between partners or across the larger community of business and customers. Constant awareness and education is required to maintain the shared language. We are living in an increasingly smaller global community. Business is built on relationships. If you invest in developing shared language, your relationships and your business will thrive.

    Background Effective communication is essential to safe and efficient patient care. Additionally, many health information technology (HIT) developments, innovations, and standards aim to implement processes to improve data quality and integrity of electronic health records (EHR) for the purpose of clinical information exchange and communication. Objective We aimed to understand the current patterns and perceptions of communication of common goals in the ICU using the distributed cognition and clinical communication space theoretical frameworks. Methods We conducted a focus group and 5 interviews with ICU clinicians and observed 59.5 hours of interdisciplinary ICU morning rounds. Results Clinicians used an EHR system, which included electronic documentation and computerized provider order entry (CPOE), and paper artifacts for documentation; yet, preferred the verbal communication space as a method of information exchange because they perceived that the documentation was often not updated or efficient for information retrieval. These perceptions that the EHR is a “shift behind” may lead to a further reliance on verbal information exchange, which is a valuable clinical communication activity, yet, is subject to information loss. Conclusions Electronic documentation tools that, in real time, capture information that is currently verbally communicated may increase the effectiveness of communication. PMID:23616870

  11. Emotional and Interactional Prosody across Animal Communication Systems: A Comparative Approach to the Emergence of Language.

    PubMed

    2016-01-01

    Across a wide range of animal taxa, prosodic modulation of the voice can express emotional information and is used to coordinate vocal interactions between multiple individuals. Within a comparative approach to animal communication systems, I hypothesize that the ability for emotional and interactional prosody (EIP) paved the way for the evolution of linguistic prosody - and perhaps also of music, continuing to play a vital role in the acquisition of language. In support of this hypothesis, I review three research fields: (i) empirical studies on the adaptive value of EIP in non-human primates, mammals, songbirds, anurans, and insects; (ii) the beneficial effects of EIP in scaffolding language learning and social development in human infants; (iii) the cognitive relationship between linguistic prosody and the ability for music, which has often been identified as the evolutionary precursor of language.

    2014-01-01

    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.

    2006-01-01

    This study compared acquisition and preference for two types of augmentative and alternative communication (AAC) systems in three pre-schoolers with autism. Acquisition of requesting behaviour using a picture-exchange system vs a voice-output communication aide (VOCA) was compared in an alternating treatments design. Following acquisition, both ACC systems were simultaneously available and the child could select which one of the two systems to use. There was little difference between picture-exchange and VOCA in terms of acquisition rates. Two children demonstrated a consistent preference for picture-exchange and the third showed a preference for the VOCA. Both speed of acquisition and system preference should be considered when designing AAC interventions for children with autism and related developmental disabilities.

    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.

  13. The cost-effectiveness of health communication programs: what do we know?

    While a considerable body of evidence has emerged supporting the effectiveness of communication programs in augmenting health, only a very small subset of studies has examined also whether these programs are cost-effective, that is, whether they achieve greater health gains for available financial resources than alternative interventions. In this article, we examine the available literature on the cost-effectiveness of health behavior change communication programs, focusing on communication interventions involving mass media, and, to a lesser extent, community mobilization and interpersonal communication or counseling. Our objective is to identify the state of past and current research efforts of the cost-effectiveness of behavior change communication programs. This review makes three principal conclusions. First, the analysis of the cost-effectiveness of health communication programs commonly has not been performed. Second, the studies reviewed here have utilized a considerable diversity of methods and have reflected varying levels of quality and adherence to standard cost-effectiveness methodologies. This leads to problems of transparency, comparability, and generalizability. Third, while the available studies generally are indicative of the cost-effectiveness of communication interventions relative to alternatives, the evidence base clearly needs to be expanded by additional rigorous cost-effectiveness analyses.

  5. Effective Interpersonal Health Communication for Linkage to Care After HIV Diagnosis in South Africa

    PubMed Central

    Mabuto, Tonderai; Charalambous, Salome

    2017-01-01

    Background: Early in the global response to HIV, health communication was focused toward HIV prevention. More recently, the role of health communication along the entire HIV care continuum has been highlighted. We sought to describe how a strategy of interpersonal communication allows for precision health communication to influence behavior regarding care engagement. Methods: We analyzed 1 to 5 transcripts from clients participating in longitudinal counseling sessions from a communication strategy arm of a randomized trial to accelerate entry into care in South Africa. The counseling arm was selected because it increased verified entry into care by 40% compared with the standard of care. We used thematic analysis to identify key aspects of communication directed specifically toward a client's goals or concerns. Results: Of the participants, 18 of 28 were female and 21 entered HIV care within 90 days of diagnosis. Initiating a communication around client-perceived consequences of HIV was at times effective. However, counselors also probed around general topics of life disruption—such as potential for child bearing—as a technique to direct the conversation toward the participant's needs. Once individual concerns and needs were identified, counselors tried to introduce clinical care seeking and collaboratively discuss potential barriers and approaches to overcome to accessing that care. Conclusions: Through the use of interpersonal communication messages were focused on immediate needs and concerns of the client. When effectively delivered, it may be an important communication approach to improve care engagement. PMID:27930608

    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

  7. I can see, hear, and smell your fear: comparing olfactory and audiovisual media in fear communication.

    PubMed

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

    2014-04-01

    Recent evidence suggests that humans can become fearful after exposure to olfactory fear signals, yet these studies have reported the effects of fear chemosignals without examining emotion-relevant input from traditional communication modalities (i.e., vision, audition). The question that we pursued here was therefore: How significant is an olfactory fear signal in the broader context of audiovisual input that either confirms or contradicts olfactory information? To test this, we manipulated olfactory (fear, no fear) and audiovisual (fear, no fear) information and demonstrated that olfactory fear signals were as potent as audiovisual fear signals in eliciting a fearful facial expression. Irrespective of confirmatory or contradictory audiovisual information, olfactory fear signals produced by senders induced fear in receivers outside of conscious access. These findings run counter to traditional views that emotions are communicated exclusively via visual and linguistic channels.

    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.

    2006-01-01

    Establishing a trusting relationship with the child patient is a critical requisite for the pediatric dentist in gaining the child's cooperation in the provision of oral health care. Developing such a relationship is predicated on the establishment of effective communication. Many publications in the psychological literature, specifically the parenting literature, describe communication skills that are relevant to the pediatric dentist in effectively communicating with children in the dental environment. Yet, several of these approaches to communication are not generally discussed or advocated in the dental literature. Among these skills are: (1) reflective listening; (2) self-disclosing assertiveness; and (3) the use of descriptive praise. This article: (1) reviews these 3 skills; (2) describes their theoretical foundations; (3) provides examples of when they are useful in the dentist-child clinical encounter; and (4) indicates why they are important aspects of the pediatric dentist's communication repertoire in establishing a positive, empathetic, and mutually cooperative relationship with the child patient.

    Is communicating anger or threats more effective in eliciting concessions in negotiation? Recent research has emphasized the effectiveness of anger communication, an emotional strategy. In this article, we argue that anger communication conveys an implied threat, and we document that issuing threats is a more effective negotiation strategy than communicating anger. In 3 computer-mediated negotiation experiments, participants received either angry or threatening messages from a simulated counterpart. Experiment 1 showed that perceptions of threat mediated the effect of anger (vs. a control) on concessions. Experiment 2 showed that (a) threat communication elicited greater concessions than anger communication and (b) poise (being confident and in control of one's own feelings and decisions) ascribed to the counterpart mediated the positive effect of threat compared to anger on concessions. Experiment 3 replicated this positive effect of threat over anger when recipients had an attractive alternative to a negotiated agreement. These findings qualify previous research on anger communication in negotiation. Implications for the understanding of emotion and negotiation are discussed.

  13. 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.

    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.

    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.

As part of the 1996 Strategic Communications Plan, a review of PAO' s current communication procedures was conducted. The 1996 Summer Faculty Fellow performed research activities to support this effort by reviewing current research concerning NASA/JSC's customers' perceptions and interests, developing communications tools which enable PAO to more effectively inform JSC customers about the Space Program, and proposing a process for developing and using consistent messages throughout PAO. Note that this research does not attempt to change or influence customer perceptions or interests but, instead, incorporates current customer interests into PAO's communication process.

    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.

    1991-01-01

    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.

    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.

    The purpose of this study was to examine the communication dynamics leading to the adoption of new attitudes and cognitions in health education sessions. We examined the verbal interactions at work in persuasive communication in 16 health education sessions. The study found that the medical expertise of the educator and the initial level of commitment of the participants had a positive effect on adherence to recommendations. However, persuasive communication in health education sessions appears to involve a paradoxical process in which criticism of the message can go hand in hand with the expression of an intention to implement new risk-reducing behaviors.

    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.

    Physics students graduate with a huge array of transferrable skills, which are extremely useful to employers (particularly in the private sector, which is the largest employment base of physicists at all degree levels). However, the key to successfully connecting with these opportunities lies in how well graduates are able to communicate their skills and abilities to potential employers. The ability to communicate effectively is a key professional skill that serves scientists in many contexts, including interviewing for jobs, applying for grants, or speaking with law and policy makers. In this interactive workshop, Crystal Bailey (Careers Program Manager at APS) and Gregory Mack (Government Relations Specialist at APS) will lead activities to help attendees achieve their goals through better communication. Topics will include writing an effective resume, interviewing for jobs, and communicating to different audiences including Congress, among others. Light refreshments will be served.

  10. Parasitoid flies exploiting acoustic communication of insects-comparative aspects of independent functional adaptations.

    Lakes-Harlan, Reinhard; Lehmann, Gerlind U C

    2015-01-01

    Two taxa of parasitoid Diptera have independently evolved tympanal hearing organs to locate sound producing host insects. Here we review and compare functional adaptations in both groups of parasitoids, Ormiini and Emblemasomatini. Tympanal organs in both groups originate from a common precursor organ and are somewhat similar in morphology and physiology. In terms of functional adaptations, the hearing thresholds are largely adapted to the frequency spectra of the calling song of the hosts. The large host ranges of some parasitoids indicate that their neuronal filter for the temporal patterns of the calling songs are broader than those found in intraspecific communication. For host localization the night active Ormia ochracea and the day active E. auditrix are able to locate a sound source precisely in space. For phonotaxis flight and walking phases are used, whereby O. ochracea approaches hosts during flight while E. auditrix employs intermediate landings and re-orientation, apparently separating azimuthal and vertical angles. The consequences of the parasitoid pressure are discussed for signal evolution and intraspecific communication of the host species. This natural selection pressure might have led to different avoidance strategies in the hosts: silent males in crickets, shorter signals in tettigoniids and fluctuating population abundances in cicadas.

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.

    2016-01-01

    Introduction: Because a comparison of noninitiators and initiators of treatment may be hopelessly confounded, guidelines for the conduct of observational research often recommend using an “active” comparator group consisting of people who initiate a treatment other than the medication of interest. In this paper, we discuss the conditions under which this approach is valid if the goal is to emulate a trial with an inactive comparator. Identification of Effects: We provide conditions under which a target trial in a subpopulation can be validly emulated from observational data, using an active comparator that is known or believed to be inactive for the outcome of interest. The average treatment effect in the population as a whole is not identified, but under certain conditions this approach can be used to emulate a trial in the subset of individuals who were treated with the treatment of interest, in the subset of individuals who were treated with the treatment of interest but not with the comparator, or in the subset of individuals who were treated with both the treatment of interest and the active comparator. The Plausibility of the Comparability Conditions: We discuss whether the required conditions can be expected to hold in pharmacoepidemiologic research, with a particular focus on whether the conditions are plausible in situations where the standard analysis fails due to unmeasured confounding by access to health care or health seeking behaviors. Discussion: The conditions discussed in this paper may at best be approximately true. Investigators using active comparator designs to emulate trials with inactive comparators should exercise caution. PMID:27891526

  16. Physician-patient argumentation and communication, comparing Toulmin's model, pragma-dialectics, and American sociolinguistics.

    Rivera, Francisco Javier Uribe; Artmann, Elizabeth

    2015-12-01

    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.

    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.

  1. Ocean environmental effects on walrus communication

    NASA Astrophysics Data System (ADS)

    Denes, Samuel L.

    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.

    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.

    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.

    2015-08-01

    Many type 2 diabetes mellitus patients have difficulties reaching optimal blood glucose control. With patients treated in primary care by nurses, nurse communication plays a pivotal role in supporting patient health. The twofold aim of the present review is to categorize common barriers to nurse-patient communication and to review potentially effective communication methods. Important communication barriers are lack of skills and self-efficacy, possibly because nurses work in a context where they have to perform biomedical examinations and then perform patient-centered counseling from a biopsychosocial approach. Training in patient-centered counseling does not seem helpful in overcoming this paradox. Rather, patient-centeredness should be regarded as a basic condition for counseling, whereby nurses and patients seek to cooperate and share responsibility based on trust. Nurses may be more successful when incorporating behavior change counseling based on psychological principles of self-regulation, for example, goal setting, incremental performance accomplishments, and action planning.

    2007-01-15

    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.

    2010-01-01

    Objective To analyze the effects that hands-free communication device (HCD) systems have on healthcare organizations from multiple user perspectives. Design This exploratory qualitative study recruited 26 subjects from multiple departments in two research sites located in Portland, Oregon: an academic medical center and a community hospital. Interview and observation data were gathered January through March, 2007. Measurements Data were analyzed using a grounded theory approach. Because this study was exploratory, data were coded and patterns identified until overall themes ‘emerged’. Results Five themes arose: (1) Communication access—the perception that HCD systems provide fast and efficient communication that supports workflow; (2) Control—social and technical considerations associated with use of an HCD system; (3) Training—processes that should be used to improve use of the HCD system; (4) Organizational change—changes to organizational design and behavior caused by HCD system implementation; and (5) Environment and infrastructure—HCD system use within the context of physical workspaces. Conclusion HCD systems improve communication access but users experience challenges integrating the system into workflow. Effective HCD use depends on how well organizations train users, adapt to changes brought about by HCD systems, and integrate HCD systems into physical surroundings. PMID:20064808

  8. Comparative tissue transcriptomics reveal prompt inter-organ communication in response to local bacterial kidney infection

    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

    Rachel Damewood; Bowen Huntsman

    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

    2015-01-01

    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

    2014-01-01

    Teamwork and communication failures are leading causes of patient safety incidents in health care. Though health care providers must work in teams, they are not well-trained in teamwork and communication skills. Health care faces the problems of differences in communication styles, communication failures and poor teamwork. There is enough evidence in the literature to show that communication failure is detrimental to patient safety. It is estimated that 80% of serious medical errors worldwide take place because of miscommunication between medical providers. NUH recognizes that effective communication and teamwork are essential in the delivery of high quality safe patient care, especially in a complex organization. NUH is a good example, where there is a rich mix of nationalities and races, in staff and in patients, and there is a rapidly expanding care environment. NUH had to overcome these challenges by adopting a multi-pronged approach. The trials and tribulations of NUH in this journey were worthwhile as the patient safety climate survey scores improved over the years.

    Background Health information technology and electronic medical records (EMRs) are potentially powerful systems-based interventions to facilitate diagnosis and treatment because they ensure the delivery of key new findings and other health related information to the practitioner. However, effective communication involves more than just information transfer; despite a state of the art EMR system, communication breakdowns can still occur. [1-3] In this project, we will adapt a model developed by the Systems Engineering Initiative for Patient Safety (SEIPS) to understand and improve the relationship between work systems and processes of care involved with electronic communication in EMRs. We plan to study three communication activities in the Veterans Health Administration's (VA) EMR: electronic communication of abnormal imaging and laboratory test results via automated notifications (i.e., alerts); electronic referral requests; and provider-to-pharmacy communication via computerized provider order entry (CPOE). Aim Our specific aim is to propose a protocol to evaluate the systems and processes affecting outcomes of electronic communication in the computerized patient record system (related to diagnostic test results, electronic referral requests, and CPOE prescriptions) using a human factors engineering approach, and hence guide the development of interventions for work system redesign. Design This research will consist of multiple qualitative methods of task analysis to identify potential sources of error related to diagnostic test result alerts, electronic referral requests, and CPOE; this will be followed by a series of focus groups to identify barriers, facilitators, and suggestions for improving the electronic communication system. Transcripts from all task analyses and focus groups will be analyzed using methods adapted from grounded theory and content analysis. PMID:19781075

    Bloemendal, Sandra; Kück, Ulrich

    2013-01-01

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

    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

    Cultural diversity is becoming increasingly more important in the workplace. This is particularly true in health care organizations facing demographic shifts in the patients served and their families. This study serves to aid the development of intercultural communication training programs for health care providers by examining how cultural sensitivity and effective intercultural communication, besides helping patients, personally benefit health care providers by reducing their stress. Effective intercultural communication and cultural sensitivity were found to be related. Health care providers' levels of intercultural anxiety also were found to correlate with effective intercultural communication.

    BACKGROUND Primary percutaneous coronary intervention (PCI) is more effective on average than fibrinolytic therapy (FT) in the treatment of ST-segment elevation myocardial infarction (STEMI). Yet most U.S. hospitals are not equipped for PCI and FT is still widely used. This study evaluated the comparative effectiveness of STEMI regionalization strategies to increase the use of PCI against standard emergency transport and care. METHODS AND RESULTS We estimated incremental treatment costs and quality-adjusted life expectancies of 2,000 patients with STEMI who received PCI or FT in simulations of emergency care in a regional hospital system. To increase access to PCI across the system, we compared a base case strategy to 12 hospital-based strategies of building new PCI labs or extending the hours of existing labs, and one emergency medical services (EMS)-based strategy of transporting all patients with STEMI to existing PCI-capable hospitals. The base case resulted in 609 (569, 647) patients getting PCI. Hospital-based strategies increased the number of patients receiving PCI, the costs of care, and quality-adjusted life years (QALYs) saved, and were cost effective under a variety of conditions. An EMS-based strategy of transporting every patient to an existing PCI facility was less costly and more effective than all hospital expansion options. CONCLUSION Our results suggest that new construction and staffing of PCI labs may not be warranted if an EMS strategy is both available and feasible. PMID:20664025

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

    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.

    Electrocommunication signals in electric fish are diverse, easily recorded and have well-characterized neural control. Two signal features, the frequency and waveform of the electric organ discharge (EOD), vary widely across species. Modulations of the EOD (i.e. chirps and gradual frequency rises) also function as active communication signals during social interactions, but they have been studied in relatively few species. We compared the electrocommunication signals of 13 species in the largest gymnotiform family, Apteronotidae. Playback stimuli were used to elicit chirps and rises. We analyzed EOD frequency and waveform and the production and structure of chirps and rises. Species diversity in these signals was characterized with discriminant function analyses, and correlations between signal parameters were tested with phylogenetic comparative methods. Signals varied markedly across species and even between congeners and populations of the same species. Chirps and EODs were particularly evolutionarily labile, whereas rises differed little across species. Although all chirp parameters contributed to species differences in these signals, chirp amplitude modulation, frequency modulation (FM) and duration were particularly diverse. Within this diversity, however, interspecific correlations between chirp parameters suggest that mechanistic trade-offs may shape some aspects of signal evolution. In particular, a consistent trade-off between FM and EOD amplitude during chirps is likely to have influenced the evolution of chirp structure. These patterns suggest that functional or mechanistic linkages between signal parameters (e.g. the inability of electromotor neurons increase their firing rates without a loss of synchrony or amplitude of action potentials) constrain the evolution of signal structure.

    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.

  16. Effective Strategies to Communicate Modeling with Project Regulators and Stakeholders

    Arola, C.; Moser, K.; Bratton, W.

    2008-12-01

    Modeling is commonly used to support environmental project decision making. A notable example of the role of groundwater flow, fate, and transport modeling is to support the CERCLA remedial investigation and feasibility study (RI/FS) process. Modeling within an RI/FS is often used to evaluate new sampling locations, or to support evaluation of potential groundwater remedial technologies. Modeling used in these efforts ranges from simple to complex, and often must fit within a variety of state and federal regulations. Project stakeholder understanding and familiarity with model tools and application ranges broadly. Effective communication of the purpose, expected outcomes, strengths, limitations, and uncertainties of modeling efforts with regulators and project stakeholders is critical to successfully support project needs. Effective communication begins prior to the implementation of modeling efforts and should continue throughout the lifecycle of the modeling project. Communication efforts should include regular project workshops to keep stakeholders apprised of modeling progress. Regular communication throughout the modeling lifecycle provides a more technically and cost effective final product due to consideration of stakeholder concerns throughout the modeling effort through information exchange and negotiation, rather than at the end of the project, when it is often too late in the process or too expensive to change course and meet project milestones.

    The purpose of this study was to compare several different measures of physician-patient communication. We compared data derived from different measures of three communication behaviors, patient participation, physician information giving, and physician participatory decision-making (PDM) style, from 83 outpatient visits to oncology or thoracic surgery clinics for pulmonary nodules or lung cancer. Communication was measured with rating scales completed by patients and physicians after the consultation and by two different groups of external observers who used rating scales or coded the frequency of communication behaviors, respectively, after listening to an audio recording of the consultation. Measures were compared using Pearson's correlations. Correlations of patients' and physicians' ratings of patient participation (r = .04) and physician PDM style (r = .03) were low and not significant (p > .0083, Bonferroni-adjusted). Correlations of observers' ratings with patients' or physicians' ratings for patient participation and physician PDM style were moderate or low (r = .15, .27, .07, and .01, respectively) but were not statistically significant (p > .0083, Bonferroni-adjusted). Correlations between observers' ratings and frequency measures were .31, .52, and .63 and were statistically significant with p values .005, <.0001, and <.0001, respectively, for PDM style, information giving, and patient participation. Our findings highlight the potential for using observers' ratings as an alternate measure of communication to more labor intensive frequency measures.

    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.

    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

    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.

    Background: Effective communication between residents with dementia and care providers in long-term care homes (LTCHs) is essential to resident-centered care. Purpose: To determine the effects of a communication intervention on residents’ quality of life (QOL) and care, as well as care providers’ perceived knowledge, mood, and burden. Method: The intervention included (1) individualized communication plans, (2) a dementia care workshop, and (3) a care provider support system. Pre- and postintervention scores were compared to evaluate the effects of the intervention. A total of 12 residents and 20 care providers in an LTCH participated in the feasibility study. Results: The rate of care providers’ adherence to the communication plans was 91%. Postintervention, residents experienced a significant increase in overall QOL. Care providers had significant improvement in mood and perceived reduced burden. Conclusion: The results suggest that the communication intervention demonstrates preliminary evidence of positive effects on residents’ QOL and care providers’ mood and burden. PMID:27899433

  2. Improved interval estimation of comparative treatment effects

    NASA Astrophysics Data System (ADS)

    Van Krevelen, Ryne Christian

    Comparative experiments, in which subjects are randomized to one of two treatments, are performed often. There is no shortage of papers testing whether a treatment effect exists and providing confidence intervals for the magnitude of this effect. While it is well understood that the object and scope of inference for an experiment will depend on what assumptions are made, these entities are not always clearly presented. We have proposed one possible method, which is based on the ideas of Jerzy Neyman, that can be used for constructing confidence intervals in a comparative experiment. The resulting intervals, referred to as Neyman-type confidence intervals, can be applied in a wide range of cases. Special care is taken to note which assumptions are made and what object and scope of inference are being investigated. We have presented a notation that highlights which parts of a problem are being treated as random. This helps ensure the focus on the appropriate scope of inference. The Neyman-type confidence intervals are compared to possible alternatives in two different inference settings: one in which inference is made about the units in the sample and one in which inference is made about units in a fixed population. A third inference setting, one in which inference is made about a process distribution, is also discussed. It is stressed that certain assumptions underlying this third type of inference are unverifiable. When these assumptions are not met, the resulting confidence intervals may cover their intended target well below the desired rate. Through simulation, we demonstrate that the Neyman-type intervals have good coverage properties when inference is being made about a sample or a population. In some cases the alternative intervals are much wider than necessary on average. Therefore, we recommend that researchers consider using our Neyman-type confidence intervals when carrying out inference about a sample or a population as it may provide them with more

  3. Cost-effectiveness analysis for health communication programs.

    Guilkey, David K; Hutchinson, Paul; Lance, Peter

    2006-01-01

    This article describes methods for analyzing the cost-effectiveness of health communication programs, focusing in particular on estimating program effectiveness with econometric methods that address experimental and quasi-experimental designs (and their absence), national or subnational program coverage, and endogenously targeting of programs. Experimental designs provide a gold standard for assessing effectiveness but are seldom feasible for large-scale health communication programs. Even in the absence of such designs, however, fairly simple methods can be used to examine intermediate objectives, such as program reach, which in turn can be linked to program costs to estimate cost effectiveness. When moving beyond program reach to behavioral or other outcome measures, such as contraceptive use or fertility, or when faced with full-coverage national programs, more elaborate data and methods are required. We discuss data requirements and assumptions necessary in each case, focusing on single-equation multiple regression models, structural equations models, and fixed effects estimators for use with longitudinal data, and then describing how cost information can be incorporated into econometric models so as to get measures of the cost-effectiveness of communication interventions.

  4. Analysis of variance of communication latencies in anesthesia: comparing means of multiple log-normal distributions.

    Ledolter, Johannes; Dexter, Franklin; Epstein, Richard H

    2011-10-01

    Anesthesiologists rely on communication over periods of minutes. The analysis of latencies between when messages are sent and responses obtained is an essential component of practical and regulatory assessment of clinical and managerial decision-support systems. Latency data including times for anesthesia providers to respond to messages have moderate (> n = 20) sample sizes, large coefficients of variation (e.g., 0.60 to 2.50), and heterogeneous coefficients of variation among groups. Highly inaccurate results are obtained both by performing analysis of variance (ANOVA) in the time scale or by performing it in the log scale and then taking the exponential of the result. To overcome these difficulties, one can perform calculation of P values and confidence intervals for mean latencies based on log-normal distributions using generalized pivotal methods. In addition, fixed-effects 2-way ANOVAs can be extended to the comparison of means of log-normal distributions. Pivotal inference does not assume that the coefficients of variation of the studied log-normal distributions are the same, and can be used to assess the proportional effects of 2 factors and their interaction. Latency data can also include a human behavioral component (e.g., complete other activity first), resulting in a bimodal distribution in the log-domain (i.e., a mixture of distributions). An ANOVA can be performed on a homogeneous segment of the data, followed by a single group analysis applied to all or portions of the data using a robust method, insensitive to the probability distribution.

    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.

    Comparative effectiveness research (CER) is the basis for some of the fiercest rhetoric of the current political era. While it is a relatively old and previously academic pursuit, CER may well become the foundation upon which the future of health care in the US is based. The actual impact of CER on-and uptake among-doctors, patients, hospitals, and health insurers, however, remains to be seen. Political considerations and compromises have led to the removal of key aspects of CER implementation from policy legislation to prevent alienating stakeholders critical to the success of health care reform. Health care providers, including specialists such as neurosurgeons, will need to understand both the policies and political implications of CER as its practices becomes an indelible part of the future health care landscape.

    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.

    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.

    Communications in any system is one of the last technologies to be considered, and sometimes it is considered too late to impact the system. This was somewhat the impression on reviewing the NASA budget for two mission scenarios for the space station. However, that budget fortunately was well spent, and the money was spent to get the most benefit per dollar. Another thing that is very often forgotten is that technology is not produced in a vacuum. In fact, in conducting independent research and development (IR&D), the first phase is to define the requirements which must be time phased, becuase very often the conditions will change during the life of the system. From the requirements, a set of architectures that are at least representative of that era are produced. If the exact requirements were not established, at least boundaries are set on the requirements for that architecture. When this is completed, then the technology that is really needed is defined. The major criticism of the work that was presented to the panel is the lack of a firm set of requirements.

    Many complex biological processes such as cell differentiation, cell proliferation, and cell motility are governed by cell signaling. This mode of intercellular communication is of paramount importance for tissue function and ultimately for entire organism. In intercellular communication cells secrete signaling molecules such as cyto/chemokines which diffuse through the surrounding medium and eventually bind to receptors on other cells whereby the signal transduction is completed. An accurate estimation of the effective communication distances and the time scale on which signaling takes place are important for the interpretation of cell and organ physiology and ultimately in the effective and efficient chemotactically driven tissue engineering. The present study uses a solitary cell model incorporating degradation of secreted molecules to estimate the effective communication distances and the time scale on which signaling takes place. We demonstrate through our model that in presence of degradation the effective communication distances are significantly reduced.

    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.

    2014-01-01

    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

In addition, the Ss were assessed on four measures of verbal and nonverbal…

  16. A comparative study of two communication models in HIV/AIDS coverage in selected Nigerian newspapers.

    2013-01-30

    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.

    We compared the effectiveness of glutaraldehyde, formaldehyde, hydrogen peroxide, peracetic acid, cupric ascorbate (plus a sublethal amount of hydrogen peroxide), sodium hypochlorite, and phenol to inactivate Bacillus subtilis spores under various conditions. Each chemical agent was distinctly affected by pH, storage time after activation, dilution, and temperature. Only three of the preparations (hypochlorite, peracetic acid, and cupric ascorbate) studied here inactivated more than 99.9% of the spore load after a 30-min incubation at 20 degrees C at concentrations generally used to decontaminate medical devices. Under similar conditions, glutaraldehyde inactivated approximately 90%, and hydrogen peroxide, formaldehyde, and phenol produced little killing of spores in suspension. By kinetic analysis at different temperatures, we calculated the rate of spore inactivation (k) and the activation energy of spore killing (delta E) for each chemical agent. Rates of spore inactivation had a similar delta E value of approximately 20 kcal/mol (ca.83.68 kJ/mol) for every substance tested. The variation among k values allowed a quantitative comparison of liquid germicidal agents. PMID:8593054

  2. Clinical handover as an interactive event: informational and interactional communication strategies in effective shift-change handovers.

    Eggins, Suzanne; Slade, Diana

    2012-01-01

    Clinical handover -- the transfer between clinicians of responsibility and accountability for patients and their care (AMA 2006) -- is a pivotal and high-risk communicative event in hospital practice. Studies focusing on critical incidents, mortality, risk and patient harm in hospitals have highlighted ineffective communication -- including incomplete and unstructured clinical handovers -- as a major contributing factor (NSW Health 2005; ACSQHC 2010). In Australia, as internationally, Health Departments and hospital management have responded by introducing standardised handover communication protocols. This paper problematises one such protocol - the ISBAR tool - and argues that the narrow understanding of communication on which such protocols are based may seriously constrain their ability to shape effective handovers. Based on analysis of audio-recorded shift-change clinical handovers between medical staff we argue that handover communication must be conceptualised as inherently interactive and that attempts to describe, model and teach handover practice must recognise both informational and interactive communication strategies. By comparing the communicative performance of participants in authentic handover events we identify communication strategies that are more and less likely to lead to an effective handover and demonstrate the importance of focusing close up on communication to improve the quality and safety of healthcare interactions.

  3. Facing the greenhouse effect: Communication about energy in Germany

    1993-01-01

    Energy policy in Germany has been characterized by an irreconcilable debate about nuclear power and the potentials of renewable energy sources and energy-saving activities for more than 15 years. The question is whether the emerging greenhouse effect has changed or at least influenced this conflict. In this study the authors screened the publications of various stakeholders in the energy debate and investigated their standpoints, values, and attitudes towards energy policy after the emergence of the greenhouse effect. The study reveals that the focus of the communication is no longer nuclear power. Moreover, communication with the public tries to hide the still virulent conflict among the agents. Every agent argues for the protection of the global climate and environment. But despite this superficial consensus and the [open quotes]green[close quotes] arguments, the various agents draw different conclusions. Thus communication not only minimizes clarity, but also fails to produce any consensus on how to realize the ambitious goals of global environmental protection. 14 refs., 2 tabs.

    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.

    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.

    Processing of cognition, affect, and intention was investigated in viewers of advertisements to prevent speeding while driving. Results indicated that anchoring-point messages had greater effects on viewers' cognition, attitude, and behavioral intention than did messages without anchoring points. Further, the changes in message anchoring points altered participants' perceptions of acceptable and unacceptable judgments: a higher anchoring point in the form of speeding mortality was more persuasive in promoting the idea of reducing driving speed. Implications for creation of effective safe driving communications are discussed.

    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

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

    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.

    Comparative effectiveness research evaluates the relative effectiveness, safety, and value of competing treatment options in clinically realistic settings. Such evaluations can be methodologically complex and difficult to interpret. There will be a growing need for critical evaluation of comparative effectiveness studies to assess the adequacy of their design and to put new information into a broader context. Equally important, this knowledge will have to be communicated to clinicians in a way that will actually change practice. We identify three challenges to effective dissemination of comparative effectiveness research findings: the difficulty of interpreting comparative effectiveness research data, the need for trusted sources of information, and the challenge of turning research results into clinical action. We suggest that academic detailing-direct outreach education that gives clinicians an accurate and unbiased synthesis of the best evidence for practice in a given clinical area-can translate comparative effectiveness research findings into actions that improve health care decision making and patient outcomes.

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

    PubMed

    2014-01-30

    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.

    Augmentative and Alternative Communication (AAC) devices include special purpose electronic devices that generate speech output and are used by individuals to augment or replace vocal communication. Word prediction, including context specific prediction, has been proposed to help overcome barriers to the use of these devices (e.g., slow communication rates and limited access to situation-related vocabulary), but has not been tested in terms of effects during actual task performance. In this study, we compared AAC device use, task performance, and user perceptions across three tasks, in conditions where the AAC device used either was, or was not, primed with task specific vocabularies. The participants in this study were adults with normal physical, cognitive, and communication abilities. Context priming had a marginally significant effect on AAC device use as measured by keystroke savings; however, these advantages did not translate into higher level measures of rate, task performance, or user perceptions. In contrast, there were various statistically significant process and performance differences across task type. Additionally, results for two different emulations of human performance showed significant keystroke savings across context conditions. However, these effects were mitigated in actual performance and did not translate into keystroke savings. This indicates to AAC device designers and users that keystroke-based measures of device use may not be predictive of high level performance.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    A critical mass of public health practitioners with expertise in analytic techniques and best practices in comparative effectiveness research is needed to fuel informed decisions and improve the quality of health care. The purpose of this case study is to describe the development and formative evaluation of a technology-enhanced comparative effectiveness research learning curriculum and to assess its potential utility to improve core comparative effectiveness research competencies among the public health workforce. Selected public health experts formed a multidisciplinary research collaborative and participated in the development and evaluation of a blended 15-week comprehensive e-comparative effectiveness research training program, which incorporated an array of health informatics technologies. Results indicate that research-based organizations can use a systematic, flexible, and rapid means of instructing their workforce using technology-enhanced authoring tools, learning management systems, survey research software, online communities of practice, and mobile communication for effective and creative comparative effectiveness research training of the public health workforce.

    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.

    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.

    2009-01-01

    Miscommunication poses a significant threat to the safety of hospitalized patients, but nurses often lack the communication confidence (self-efficacy) needed to represent their views regarding patient situations. Findings of this study suggest training programs are needed to help nurses develop confident, assertive communication skills.

  7. An introduction to Doppler effect and fading in mobile communications

    Depaula, Abdon B.

    1992-12-01

    In this research we present an introductory analysis of a complex aspect of mobile communications: Doppler effect is evaluated in both Ricean and Rayleigh channels. A noncoherent 2-FSK scheme is selected to evaluate the behavior of the system under very strong fading channel conditions. The analysis is conducted for the binary case due to the possibility of developing closed form solutions. Therefore, the approach is simplified avoiding long lasting simulations that may obscure the concepts. The probability of bit error for the 2-FSK case can also be used as an initial bound for a M-FSK scheme. Diversity is evaluated as a means of combating fading and Doppler effects. Error correcting codes, in the form of a convolutional codes, are also used and applied to both effects.

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

    NASA Astrophysics Data System (ADS)

    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.

    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.

  10. 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.

  11. The politics of comparative effectiveness research: lessons from recent history.

    PubMed

    Sorenson, Corinna; Gusmano, Michael K; Oliver, Adam

    2014-02-01

    Efforts to support and use comparative effectiveness research (CER), some more successful than others, have been promulgated at various times over the last forty years. Following a resurgence of interest in CER, recent health care reforms provided substantial support to strengthen its role in US health care. While CER has generally captured bipartisan support, detractors have raised concerns that it will be used to ration services and heighten government control over health care. Such concerns almost derailed the initiative during passage of the health care reform legislation and are still present today. Given recent investments in CER and the debates surrounding its development, the time is ripe to reflect on past efforts to introduce CER in the United States. This article examines previous initiatives, highlighting their prescribed role in US health care, the reasons for their success or failure, and the political lessons learned. Current CER initiatives have corrected for many of the pitfalls experienced by previous efforts. However, past experiences point to a number of issues that must still be addressed to ensure the long-term success and sustainability of CER, including adopting realistic aims about its impact, demonstrating the impact of Patient-Centered Outcomes Research Institute (PCORI) and communicating the benefits of CER, and maintaining strong political and stakeholder support.

  13. Shaping effective communication skills and therapeutic relationships at work: the foundation of collaboration.

    PubMed

    Grover, Susan M

    2005-04-01

    Effective communication is essential to practice and can result in improved interpersonal relationships at the workplace. Effective communication is shaped by basic techniques such as open-ended questions, listening, empathy, and assertiveness. However, the relationship between effective communication and successful interpersonal relationships is affected by intervening variables. The variables of gender, generation, context, collegiality, cooperation, self-disclosure, and reciprocity can impede or enhance the outcome of quality communication. It is essential for occupational health nurses to qualitatively assess the degree to which each of these concepts affects communication and, in turn, relationships at work.

  16. Size and scale effects as constraints in insect sound communication

    PubMed Central

    Bennet-Clark, H. C.

    1998-01-01

    For optimal transfer of power to the surrounding medium, a sound source should have a radius of 1/6 to 1/4 of the sound wavelength. Sound-waves propagate from the source as compressions and rarefactions of the fluid medium, which decay by spreading and viscous losses. Higher frequencies are more easily refracted and reflected by objects in the environment, causing degradation of signal structure. In open air or water, the sound spreads spherically and decays by the inverse square law. If the sound is restricted to two dimensions rather than three, it decays as the inverse of range, whereas waves within a rod decay largely due to viscous losses; such calls are usually rather simple pulses and rely on the initial time of arrival because of multiple pathlengths or different propagation velocities in the environment. Because of the relationship between calling success and reproductive success, singing insects are under selective pressure to optimize the range, and to maintain the specificity, of their calls. Smaller insects have less muscle power; because of their small sound sources, higher frequencies will be radiated more efficiently than lower frequencies, but in order to produce brief loud pulses from a long-duration muscle contraction they may use both a frequency multiplier mechanism and a mechanical power amplifier. Airborne insect sounds in the range from 1 to 5 kHz tend to have sustained puretone components and a specific pattern of pulses which propagate accurately. Where the song frequency is higher, the pulses tend to become briefer, with a rapid initial build-up that gives a reliable time of onset through obstructed transmission pathways. These scale effects may be related both to the sound-producing mechanism and the auditory system of the receiver. Tiny insects have the special acoustic problem of communicating with only a small amount of available power. Some, such as fruit flies, communicate at low frequencies, at close range, by generating air

    Abstract Objective: Compare the non-verbal communication of children before and during interaction with clowns and compare their vital signs before and after this interaction. Methods: Uncontrolled, intervention, cross-sectional, quantitative study with children admitted to a public university hospital. The intervention was performed by medical students dressed as clowns and included magic tricks, juggling, singing with the children, making soap bubbles and comedic performances. The intervention time was 20min. Vital signs were assessed in two measurements with an interval of 1min immediately before and after the interaction. Non-verbal communication was observed before and during the interaction using the Non-Verbal Communication Template Chart, a tool in which non-verbal behaviors are assessed as effective or ineffective in the interactions. Results: The sample consisted of 41 children with a mean age of 7.6±2.7 years; most were aged 7-11 years (n=23; 56%) and were males (n=26; 63.4%). There was a statistically significant difference in systolic and diastolic blood pressure, pain and non-verbal behavior of children with the intervention. Systolic and diastolic blood pressure increased and pain scales showed decreased scores. Conclusions: The playful interaction with clowns can be a therapeutic resource to minimize the effects of the stressing environment during the intervention, improve the children's emotional state and reduce the perception of pain.

  7. Known unknowns: indirect energy effects of information and communication technology

    NASA Astrophysics Data System (ADS)

    Horner, Nathaniel C.; Shehabi, Arman; Azevedo, Inês L.

    2016-10-01

    Background. There has been sustained and growing interest in characterizing the net energy impact of information and communication technology (ICT), which results from indirect effects offsetting (or amplifying) the energy directly consumed by ICT equipment. These indirect effects may be either positive or negative, and there is considerable disagreement as to the direction of this sign as well as the effect magnitude. Literature in this area ranges from studies focused on a single service (such as e-commerce versus traditional retail) to macroeconomic studies attempting to characterize the overall impact of ICT. Methods. We review the literature on the indirect energy effect of ICT found via Google Scholar, our own research, and input from other researchers in the field. The various studies are linked to an effect taxonomy, which is synthesized from several different hierarchies present in the literature. References are further grouped according to ICT service (e.g., e-commerce, telework) and summarized by scope, method, and quantitative and qualitative findings. Review results. Uncertainty persists in understanding the net energy effects of ICT. Results of indirect energy effect studies are highly sensitive to scoping decisions and assumptions made by the analyst. Uncertainty increases as the impact scope broadens, due to complex and interconnected effects. However, there is general agreement that ICT has large energy savings potential, but that the realization of this potential is highly dependent on deployment details and user behavior. Discussion. While the overall net effect of ICT is likely to remain unknown, this review suggests several guidelines for improving research quality in this area, including increased data collection, enhancing traditional modeling studies with sensitivity analysis, greater care in scoping, less confidence in characterizing aggregate impacts, more effort on understanding user behavior, and more contextual integration across the

    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.

  11. Comparing communicative competence in child and chimp: the pragmatics of repetition.

    PubMed

    Greenfield, P M; Savage-Rumbaugh, E S

    1993-02-01

    Through an analysis of chimpanzee-human discourse, we show that two Pan troglodytes chimpanzees and two Pan paniscus chimpanzees (bonobos) exposed to a humanly devised symbol system use partial or complete repetition of others' symbols, as children do: they do not produce rote imitations, but instead use repetition to fulfil a variety of pragmatic functions in discourse. These functions include agreement, request, promise, excitement, and selection from alternatives. In so doing, the chimpanzees demonstrate contingent turn-taking and the use of simple devices for lexical cohesion. In short, they demonstrate conversational competence. Because of the presence of this conversational competence in three sibling species, chimpanzees, bonobos, and humans, it is concluded that the potential to express pragmatic functions through repetition was part of the evolutionary history of human language, present in our common ancestor before the phylogenetic divergence of hominids and chimpanzees. In the context of these similarities, two interesting differences appeared: (I) Human children sometimes used repetition to stimulate more talk in their conversational partner; the chimpanzees, in contrast, use repetition exclusively to forward the non-verbal action. This difference may illuminate a unique feature of human linguistic communication, or it may simply reflect a modality difference (visual symbols used by the chimpanzees, speech used by the children) in the symbol systems considered in this research. A second difference seems likely to reflect a true species difference: utterance length. The one- and two-symbol repetitions used by the chimpanzees to fulfil a variety of pragmatic functions were less than half the maximum length found in either the visual symbol combinations addressed to them by their adult human caregivers or the oral repetitions of two-year-old children. This species difference probably reflects the evolution of increased brain size and consequent increased

    Gann, T. M.; Conklin, M. H.; Gonzales, J. P.; Matlock, T.

    2014-12-01

    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.

    2005-01-01

    Much evaluation of health communications in public health is considered from a program perspective of smoking cessation, weight reduction, education on sexually transmitted diseases, etc. These studies have advanced the knowledge base of communications theory and evaluation and have contributed to program effectiveness. In program-based evaluation the communications process is structured as part of the program itself. This article extends program-based communications evaluation to view communications from the perspective of the consumer and how effectively public health departments respond to consumer expectations. It develops a conceptual model for evaluating elements of communications such as its importance in defining mission and goals within the community, managing strategic constituencies, and enlisting individuals and groups as customers and co-producers of health. It gives a broader perspective on how communications in public heath organizations are managed and a basis for assessing whether they are being managed effectively.

    PubMed

    Namkoong, Kang; Nah, Seungahn; Record, Rachael A; Van Stee, Stephanie K

    2017-01-01

    This study examines direct and indirect effects of interactive communication in an antismoking social media campaign. To that end, we pose a multitheoretical framework that integrates communication mediation models and the Theory of Planned Behavior. To test the theorized model, we conducted an experiment using a two-group pretest-posttest design. Participants (N = 201) were randomly assigned into two experimental conditions: "campaign message reception only" as a control group and "message reception and social interaction" as a treatment group, in which the participants contributed to the antismoking campaign by posting their own campaign ideas and information they found through mediated and interpersonal communication. The findings show that interactive communication catalyzes the participants' information searching behaviors through diverse communication channels. In turn, increased media use plays a crucial role in changing their attitudes and perceived social norms about smoking behaviors, and eventually reducing smoking intention. This study affirms that the theory of planned behavior is effective in predicting behavioral intention and demonstrates the usefulness of a multitheoretical approach in interactive campaign research on social media.

    2008-08-01

    The present study was conducted to examine the effects of communication skills on stress responses, such as physiological (blink and heart rate), emotional (state of anxiety and mood), and behavioral responses (smiling and expressing an opinion) in stressful communication situations, specifically answering questions and giving a speech in Japanese and English. Participants were 32 students (16 men and 16 women; Mage = 19.5 yr., SD = 1.3) attending a Japanese university. A high communication skills group was selected from the upper tertile scores of the Social Skills Inventory, and a low communication skills group was selected from the lower tertile scores. Analysis indicated that individuals who had high communication skills performed without heart-rate increase and with more positive attitude during stressful communication tasks. Individuals who had low communication skills displayed higher anxiety prior to the experiment than those who had high communication skills.

    Previous research with groups of individually isolated crews communicating and problem-solving in a distributed interactive simulation environment has shown that the functional interchangeability of available communication channels can serve as an effective countermeasure to communication constraints. The present report extends these findings by investigating crew performance effects and psychosocial adaptation following: (1) the loss of all communication channels, and (2) changes in crew configuration. Three-person crews participated in a simulated planetary exploration mission that required identification, collection, and analysis of geologic samples. Results showed that crews developed and employed discrete navigation system operations that served as functionally effective communication signals (i.e., “indexical” or “deictic” cues) in generating appropriate crewmember responses and maintaining performance effectiveness in the absence of normal communication channels. Additionally, changes in crew configuration impacted both performance effectiveness and psychosocial adaptation.

    Background Medical stores management in hospitals is a tedious and time consuming chore with limited resources tasked for the purpose and poor penetration of Information Technology. The process of automation is slow paced due to various inherent factors and is being challenged by the increasing inventory loads and escalating budgets for procurement of drugs. Methods We carried out an indepth case study at the Medical Stores of a tertiary care health care facility. An iterative six step Quality Improvement (QI) process was implemented based on the Plan–Do–Study–Act (PDSA) cycle. The QI process was modified as per requirement to fit the medical stores management model. The results were evaluated after six months. Results After the implementation of QI process, 55 drugs of the medical store inventory which had expired since 2009 onwards were replaced with fresh stock by the suppliers as a result of effective communication through upgraded database management. Various pending audit objections were dropped due to the streamlined documentation and processes. Inventory management improved drastically due to automation, with disposal orders being initiated four months prior to the expiry of drugs and correct demands being generated two months prior to depletion of stocks. The monthly expense summary of drugs was now being done within ten days of the closing month. Conclusion Improving communication systems within the hospital with vendor database management and reaching out to clinicians is important. Automation of inventory management requires to be simple and user-friendly, utilizing existing hardware. Physical stores monitoring is indispensable, especially due to the scattered nature of stores. Staff training and standardized documentation protocols are the other keystones for optimal medical store management. PMID:26900225

  2. Comparative international analysis of radiofrequency exposure surveys of mobile communication radio base stations.

    PubMed

    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.

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

    PubMed

    Henderson, Julie K

    2005-01-01

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

    Radioactive materials (sources) are managed by bookkeeping and stocktaking. The radiation protection section staffs should check the sources manually. Annual effective dose concerning stocktaking of them are estimated at some mSv concerning fingers. A radio frequency identification (RFID) tag's absorbed dose is estimated at some dozen Gy. RFID for stocktaking automatically was devised. Radiation effects on the communication performance of RFID tags were investigated by using response times and read ranges as indices. The RFID system was composed of a computer, a detector, and transponders (tag) consisting of an integrated circuit chip and an antenna. The tag is joined to the source for identification. The tags were irradiated at doses between 5 and 5,000 Gy by an x-ray irradiator. The response times and the read ranges were tracked from 40 to 23,200 min after irradiation. Relative read ranges fluctuated between 0.9 and 1.1 in the dose region less than 2,000 Gy, but fluctuated greatly in the dose region beyond 2,000 Gy. Malfunctioning tags appeared from 3,000 Gy, and all tags malfunctioned in the dose region over 4,500 Gy. The threshold dose leading to malfunction was determined to be 2,100 Gy. Time variation of relative read ranges was classified into four patterns. The pattern shifted from pattern 1 to 4 when the dose was increased. The relative read ranges lengthened in pattern 1. The relative read rages were approximately 1.0 in pattern 2. The read ranges tentatively shortened, then recovered in pattern 3. The tags malfunctioned in pattern 4. Once the tags malfunctioned, they never recovered their performance. Radiation enhances or deteriorates communication performance depending on dosage. Tags can spontaneously recover from radiation deterioration. The time variation of the read ranges can be illustrated by enhancement, deterioration, and recovery. The mechanism of four patterns is explained based on the variation of the frequency harmonization strength and

    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.

    2010-04-01

    Effects of beam wander on uncoded bit-error-rate (BER) of direct-detection OOK modulated FSO communication systems using collimated and focused Gaussian beams are studied. Channel fading statistics are obtained from large-scale wave optics simulations and compared with the closed-form log-normal and gamma-gamma models. The avalanche photodiode (APD) is chosen for photodetection. The accurate McIntyre-Conradi APD model is adopted for performance evaluation. Results show that large performance gain (more than 15dB) can be achieved with fast-tracked focused beams. The upper bound of higher-order adaptive optics gain beyond tracking gain is also studied.

    Parent-child communication about sex is an important reproductive health outcome. Consistent, positive perceptions of communication by parents and children can promote behavioral outcomes such as delaying sexual debut and increasing contraceptive use. The authors investigated whether exposure to messages from the Parents Speak Up National Campaign (PSUNC), a social marketing campaign to promote increased parent-child sexual communication, led to increased children's self-reports of communication. Also, the authors examined whether PSUNC message exposure increased agreement about communication between parents and their children. In a randomized experimental design, the authors surveyed children of parents exposed and not exposed to PSUNC messages. Parents and children completed online instruments asking matched questions about sexual attitudes, beliefs, and communication. The authors matched 394 parents and children for analysis. They used ordinal logistic regression modeling and kappa statistics. Children of parents exposed to PSUNC messages were more likely to (a) report sexual communication than were those not exposed and (b) agree with their parents about extent and content. Parent-child pairs of the same gender, younger pairs, and non-White pairs were more likely to agree. Overall, PSUNC message exposure appears to have promoted more extensive sexual communication. Future research should examine behavioral mechanisms and message receptivity among subgroups of parents and children.

  15. Effective Use of Social Media in Communicating Climate Science

    NASA Astrophysics Data System (ADS)

    Sinclair, P. W.

    2012-12-01

    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.

    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.

    The Lerner Research Institute's core services support all investigators at Cleveland Clinic, including a group of nearly 200 research faculty and their teams, as well as clinical research groups who need access to our centralized technologies. We offer approximately 20 different types of services and instruments ranging from preparation of media and cell lines to genomics and proteomics resources. Services are also available to the greater Cleveland scientific community, with selected cores open to “external” (i.e. non-Cleveland) users as long as capacity permits. Beyond the expected technical and scientific expertise, LRI researchers rely on the cores heavily for education and advice on emerging methodologies and research trends. Core structure is kept flexible by design; annual evaluations of the demand, cost-effectiveness, staffing, and customer satisfaction for each core guide decisions about continued operation or restructuring. The LRI cores are supported in part by the Cleveland Translational Science Collaborative, by the Case Comprehensive Cancer Center, and by multiple PPGs to individual investigators. Resolution of differences in objectives, policies, direction, reporting, and allowable practices among funding sources requires constant, highly effective communication. To this end, we have found that a seemingly pedestrian approach – frequent meetings, scrupulous meeting attendance and insightful, diplomatic selection of meeting participants and agendas – when used consistently and inclusively, has proven effective in resolving most conflicts and generating compromises. In the best of cases, this enlightened cooperativity can result in development of services beyond the standard core fare, such as the development of a service to distribute highly purified, elutriated human peripheral blood cells, made possible by the Clinical Research Unit Core Laboratory in collaboration with 2 PPGs and with the TTR component of the CTSC.

    Lima, Julie C; Intrator, Orna; Wetle, Terrie

    2015-01-01

    Objectives To develop a measure of the perceptions of nursing home (NH) Directors of Nursing (DON) on the adequacy of physician care and to examine its variation as well as its construct validity. Design A nationwide cross-sectional study with primary data collection Setting 2043 NHs surveyed August 2009 – April 2011 Participants Directors of Nursing (DONs) and NH Administrators responded to questions pertaining to their perceptions of the care provided by physicians in their NH. Measurements Ten items were used to create three domains: medical staff attentiveness, physician communication, and staff concerns about physician practice. These were combined into an overall summary score measure called “Effectiveness of Physician Accountability and Communication” (EPAC). EPAC construct validity was ascertained from other DON questions and from a complementary survey of NH Administrators. RESULTS The established EPAC score is the first measure to capture specific components of the adequacy of physician care in NHs. EPAC exhibited good construct validity: more effective practices were correlated with greater physician involvement in discussions of Do-Not-Resuscitate orders, the frequency that the Medical Director checked on the medical care delivered by attending physician, the tightness of nursing home's control of its physician resources, and the DON's perception of whether or not avoidable hospitalizations and ER visits could be reduced with greater physician attention to resident needs. Conclusion As increased attention is given to the quality of care provided to vulnerable elders, effective measures of processes of care are essential. The EPAC measure provides an important new metric that can be used in these efforts. The goal is that future studies could use EPAC and its individual domains to shed light on the manner through which physician presence is related to resident outcomes in the NH setting.

    This Review examines recommendations and principles that promote good decision-making with regard to the insertion, deactivation, and potential malfunction of implantable cardioverter-defibrillators (ICDs). This guidance is important because ICDs are now used for primary and secondary prevention of arrhythmias in more than 20 diverse clinical populations, which accounts for the exponential increase in insertion rates over the past decade. Current guidelines require clinicians to provide personalized, culturally appropriate, and easy to understand information to patients on the benefits and harms of proposed treatment choices; however, obtaining valid informed consent for insertion and deactivation of ICDs is challenging. Initiating early conversations with patients and continuing this dialogue over time, implementation of localized care protocols, increased collaboration (particularly between cardiac and palliative care teams), and the provision of training for all health professionals involved in the care of these patients, can help to ensure that adequate informed consent is maintained throughout their care. In addition to providing information, health professionals should identify and address high levels of anxiety in patients and their next of kin and promote effective communication throughout decision making. In the future, use of standardized checklists or decision aids based on a clear understanding of the principles underlying key topics could support this process.

  1. Effects of checklist interface on non-verbal crew communications

    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.

    In most countries, people who have a low socioeconomic status and those who live in poor or marginalised communities have a higher risk of dying from non-communicable diseases (NCDs) than do more advantaged groups and communities. Smoking rates, blood pressure, and several other NCD risk factors are often higher in groups with low socioeconomic status than in those with high socioeconomic status; the social gradient also depends on the country's stage of economic development, cultural factors, and social and health policies. Social inequalities in risk factors account for more than half of inequalities in major NCDs, especially for cardiovascular diseases and lung cancer. People in low-income countries and those with low socioeconomic status also have worse access to health care for timely diagnosis and treatment of NCDs than do those in high-income countries or those with higher socioeconomic status. Reduction of NCDs in disadvantaged groups is necessary to achieve substantial decreases in the total NCD burden, making them mutually reinforcing priorities. Effective actions to reduce NCD inequalities include equitable early childhood development programmes and education; removal of barriers to secure employment in disadvantaged groups; comprehensive strategies for tobacco and alcohol control and for dietary salt reduction that target low socioeconomic status groups; universal, financially and physically accessible, high-quality primary care for delivery of preventive interventions and for early detection and treatment of NCDs; and universal insurance and other mechanisms to remove financial barriers to health care.

    2010-01-01

    Background Effective nonpharmacological interventions are needed to treat neuropsychiatric symptoms and improve quality of life for the 5.3 million Americans affected by dementia. Objective To test the effect of a storytelling program, TimeSlips, on communication, neuropsychiatric symptoms, and quality of life in long-term care residents with dementia. Method A quasi-experimental, two-group, repeated measures design was used to compare persons with dementia who were assigned to the twice-weekly, 6-week TimeSlips intervention (n = 28) or usual care (n = 28) group at baseline and postintervention at Weeks 7 and 10. Outcome measures included the Cornell Scale for Depression in Dementia, Neuropsychiatric Inventory-Nursing Home Version, Functional Assessment of Communication Skills, Quality of Life–AD, and Observed Emotion Rating Scale (this last measure was collected also at Weeks 3 and 6 during TimeSlips for the treatment group and during mealtime for the control group). Results Compared to the control group, the treatment group exhibited significantly higher pleasure at Week 3 (p < .001), Week 6 (p < .001), and Week 7 (p < .05). Small to moderate treatment effects were found for Week 7 Social Communication (d = .49) and Basic Needs Communication (d = .43). A larger effect was found for pleasure at Week 7 (d = .58). Discussion As expected given the engaging nature of the TimeSlips creative story-telling intervention, analyses revealed increased positive affect during and at 1-week post-intervention. In addition, perhaps associated with the intervention’s reliance on positive social interactions and verbal communication, participants evidenced improved communication skills. However, more frequent dosing and booster sessions of TimeSlips may be needed to show significant differences between treatment and control groups on long-term effects and other outcomes.

    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.

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

    Intra-body communication (IBC) is a new, different "wireless" communication technique based on the human tissue. This short range "wireless" communication technology provides an alternative solution to wearable sensors, home health system, telemedicine and implanted devices. The development of the IBC enables the possibilities of providing less complexity and convenient communication methodologies for these devices. By regarding human tissue as communication channel, IBC making use of the conductivities properties of human tissue to send electrical signal from transmitter to receiver. In this paper, the authors proposed a new mathematical model for galvanic coupling type IBC based on a human limb. Starting from the electromagnetic theory, the authors treat human tissue as volume conductor, which is in analogous with the bioelectric phenomena analysis. In order to explain the mechanism of galvanic coupling type technique of IBC, applying the quasi-static approximation, the governing equation can be reduced to Laplace Equation. Finally, the analytical model is evaluated with on-body measurement for testing its performance. The comparison result shows that the developed mathematical model can provide good approximation for galvanic coupling type IBC on human limb under low operating frequencies.

    This version of the communication primer comprises two interlocking parts: Pat 1, a practical section, intended to prepare you for public interactions, and Part 2, a theoretical section that provides social and technical bases for the practices recommended in Part 1. The mutual support of practice and theory is very familiar in science and clearly requires a willingness to observe and revise our prior assumptions--in this document, we invoke both. We hope that is offering will represent a step both towards improving practice and maturing the theory of practical science communication.

  2. The effects of Computerized Provider Order Entry implementation on communication in Intensive Care Units.

    2013-05-01

    The literature shows that communication in health care is one of the most important factors associated with quality of care and patients safety. Especially in Intensive Care Units (ICUs) communication is of importance, due to the characteristics of the setting. However, relatively little is known about the different aspects of communication in health care and how Computerized Provider Order Entry (CPOE) implementation may impact communication, and consequently, quality of care. In this study we adapted an existing questionnaire developed by Shortell et al. to examine the impact of CPOE implementation on communication in a repeated cross-sectional design (6 months before implementation, 3 months after implementation and one-year after implementation). Results show overall that CPOE did not have a negative effect on communication, especially in the long term.

    2012-01-01

    Studies investigating factors contributing to improved quality of care have found that effective team member communication is among the most critical and influential aspects in the delivery of quality care. Relatively little research has examined the role of the physical design of nursing units on communication patterns among care providers. Although the concept of decentralized unit design is intended to increase patient safety, reduce nurse fatigue, and control the noisy, chaotic, and crowded space associated with centralized nursing stations, until recently little attention has been paid to how such nursing unit designs affected communication patterns or other medical and organizational outcomes. Using a pre/post research design comparing more centralized or decentralized unit designs with a new multi-hub design, the aim of this study was to describe the relationship between the clinical spatial environment and its effect on communication patterns, nurse satisfaction, distance walked, organizational outcomes, patient safety, and patient satisfaction. Hospital institutional data indicated that patient satisfaction increased substantially. Few significant changes were found in communication patterns; no significant changes were found in nurse job satisfaction, patient falls, pressure ulcers, or organizational outcomes such as average length of stay or patient census.

    2004-03-01

    The effect of immediate verbal feedback on trainer behaviour during communication training sessions with individuals with intellectual disability (ID) was assessed. Trainers were six undergraduate university students majoring in psychology. The procedure consisted of interrupting the sequence of trials of training by the supervisor and then giving brief corrective feedback. Feedback was focused on the accuracy of the following procedural aspects: (1) entry behaviour; (2) prompt level and order of presenting response prompts; (3) use of reinforcement; (4) pace of presenting trials; and (5) if this occurred, handling trainee's disruptive behaviour during training. Data were collected in a nonconcurrent multiple baseline design. Results indicated a statistically significant increase of the percentage correct trainer behaviour as compared to the baseline phase. Maintenance of effect of feedback was recorded during post-training and follow-up.

    PubMed

    Fujino, Yuriko; Kawamoto, Rieko

    2013-05-01

    The aim of this study was to investigate the influence of information and communication technology use and skills on nursing performance. Questionnaires were prepared relating to using the technology, practical skills in utilizing information, the Six-Dimension Scale of Nursing Performance, and demographics. In all, 556 nurses took part (response rate, 72.6%). A two-way analysis of variance was used to determine the influence of years of nursing experience on the relationship between nursing performance and information and communication technology use. The results showed that the group possessing high technological skills had greater nursing ability than the group with low skills; the level of nursing performance improved with years of experience in the former group, but not in the latter group. Regarding information and communication technology use, the results showed that nursing performance improved among participants who used computers for sending and receiving e-mails, but it decreased for those who used cell phones for e-mail. The results suggest that nursing performance may be negatively affected if information and communication technology are inappropriately used. Informatics education should therefore be provided for all nurses, and it should include information use relating to cell phones and computers.

    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.

    2004-10-01

    This randomized study evaluated the combined effect of a cognitive-communication program plus an acetylcholinesterase inhibitor (donepezil; donepezil-plus-stimulation group; n = 26), as compared with donepezil alone (donepezil-only group; n = 28) in 54 patients with mild to moderate Alzheimer's disease (AD; Mini-Mental Status Examination score of 12- 28) ranging in age from 54 to 91 years. It was hypothesized that cognitive-communication stimulation in combination with donepezil would positively affect the following: (a) relevance of discourse, (b) performance of functional abilities, (c) emotional symptoms, (d) quality of life, and (e) overall global function, as measured by caregiver and participant report and standardized measures. Cognitive-communication, neuropsychiatric, functional performance, and quality of life evaluations were conducted at baseline and Month 4, the month after the 2-month active stimulation period. Follow-up evaluations were performed at Months 8 and 12. The stimulation program consisted of 12 hr of intervention over an 8-week period and involved participant-led discussions requiring homework, interactive sessions about AD, and discussions using salient life stories. Additive effects of active stimulation with donepezil were examined in 2 ways: (1) comparing mean group performance over time and (2) evaluating change scores from baseline. A Group x Time interaction was found for the donepezil-plus-stimulation group in the emotional symptoms of apathy and irritability as compared with the donepezil-only group. Evaluation of change scores from baseline to 12 months revealed a positive effect for the donepezil-plus-stimulation group on discourse and functional abilities with a trend on apathy, irritability, and patient-reported quality of life. In sum, the research revealed benefits to the donepezil-plus-stimulation group in the areas of discourse abilities, functional abilities, emotional symptoms, and overall global performance.

  16. Teaching communication skills in clinical settings: comparing two applications of a comprehensive program with standardized and real patients

    PubMed Central

    2014-01-01

    Background Communication is important for the quality of clinical practice, and programs have been implemented to improve healthcare providers’ communication skills. However, the consistency of programs teaching communication skills has received little attention, and debate exists about the application of acquired skills to real patients. This study inspects whether (1) results from a communication program are replicated with different samples, and (2) results with standardized patients apply to interviews with real patients. Methods A structured, nine-month communication program was applied in two consecutive years to two different samples of healthcare professionals (25 in the first year, 20 in the second year). Results were assessed at four different points in time, each year, regarding participants’ confidence levels (self-rated), basic communication skills in interviews with standardized patients, and basic communication skills in interviews with real patients. Data were analyzed using GLM Repeated-Measures procedures. Results Improvements were statistically significant in both years in all measures except in simulated patients’ assessment of the 2008 group. Differences between the two samples were non-significant. Differences between interviews with standardized and with real patients were also non-significant. Conclusions The program’s positive outcomes were replicated in different samples, and acquired skills were successfully applied to real-patient interviews. This reinforces this type of program structure as a valuable training tool, with results translating into real situations. It also adds to the reliability of the assessment instruments employed, though these may need adaptation in the case of real patients. PMID:24886341

  19. 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.

  20. 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.

    A comparative magnetic field effect (MFE) study was done on indole exciplexes with various acceptors, anthracene, pyrene, all-s- trans-1,4-diphenylbuta-1,3-diene and 9-cyanophenanthrene. A surprisingly low magnetic field effect was detected for the 9-cyanophenanthrene exciplexes and was correlated with exciplex geometry. The wavelength dependence of magnetic field effect confirms the presence of single charge-transfer complex for all the exciplexes with 1,2-dimethylindole.

    Sulodexide represents a novel antithrombotic agent with multiple sites of action on blood coagulation and vascular processes. The purpose of this study was to compare sulodexide and enoxaparin on anticoagulant effects, tissue factor (TF)-induced activation of platelets, inhibition of microparticle generation and to investigate their effect on heparin-induced platelet aggregation (HIPA). Sulodexide was compared with enoxaparin at equigravimetric concentrations. When compared to enoxaparin, sulodexide produced a stronger anticoagulant effect in the prothrombin time (PT), activated partial thromboplastin time (APTT), Heptest, and thrombin time (TT) assays. In addition, sulodexide had a stronger inhibitory effect on TF-mediated microparticle generation (IC(50) = 2.8 microg/ mL), P-selectin expression (IC(50) = 4.8 microg/ml), and platelet aggregate formation (IC(50) = 8.5 microg/mL) compared to higher IC(50) values with enoxaparin. Sulodexide and enoxaparin exhibited a similar effect on heparin-induced thrombocytopenia (HIT) antibody-mediated platelet activation HIPA assays. These results suggest that sulodexide is a relatively stronger anticoagulant agent than enoxaparin. Sulodexide is subcutaneously absorbed. Its ability to inhibit TF-mediated platelet activation may contribute to the observed therapeutic effects of sulodexide in microvascular vasculopathy such as diabetic nephropathy. These results also suggest that inhibition of TF activation of platelets by sulodexide may be independent of its anticoagulant effects. These results warrant further investigation of sulodexide in additional preclinical and clinical studies.

    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.

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

    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

    Effects of task interdependence and communication technologies synchrony on performance in virtual teams. Survey results of 197 employees from 41 work groups in a large multinational software firm were used to investigate the effects of within-group task interdependence and the degree of communication synchrony on performance in virtual teams (VTs). The analyses revealed a moderating effect of task interdependence on the relationship between the degree of communications synchrony and performance in VT. We found that superior VTs performance is contingent on the fit between the nature of the task (i.e., task interdependence) and the choice of communications modality. This study complements previous research providing additional evidence of how task-technology interaction affects VTs performance, and extends previous findings obtained with ad-hoc groups in laboratory settings to natural, organizational teams.

  9. The Exposure Advantage: Early Exposure to a Multilingual Environment Promotes Effective Communication.

    2015-07-01

    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 both bilingual children and children who were exposed to a multilingual environment but were not bilingual themselves. Children who were merely exposed to a second language performed as well as bilingual children, despite having lower executive-function scores. Thus, the communicative advantages demonstrated by the bilinguals 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.

  10. Comparative effectiveness of helicopter emergency medical services compared to ground emergency medical services.

    The use of helicopter emergency medical services (HEMS) for the transportation and treatment of trauma patients, while commonplace in most developed nations, remains controversial. The purported beneficial effects of HEMS compared to ground emergency medical services is likely to be some combination of speed, crew expertise, and the fact that HEMS is part of an organized trauma system. When the HEMS literature is assessed as a whole, considerable heterogeneity of effects and study methodologies preclude an accurate estimate of composite effect. However, when the outcome of mortality is studied using advanced multivariable regression techniques to control for multiple known confounders, an improved odds of survival has been repeatedly demonstrated. Future HEMS research must rely on robust observational study designs and assessments of a variety of patient outcomes. Questions about the role of speed, distance, and other potentially beneficial elements of HEMS remain.

    Smoke from plastics can cause immediate problems in electrical equipment in the form of shorting and increased leakage currents, as well as long-term corrosion (metal loss). The short-term problems can be especially serious for critical control instrumentation such as that found in nuclear reactors or telecommunications systems. The US Nuclear Regulatory Commission and Sandia National Laboratories are sponsoring a program to determine the modes and probabilities of digital equipment failure during exposure to smoke and up to 24 hours after the exposure. Early tests on computer systems have shown that the most common immediate problems are temporary and are likely to be caused by increased leakage currents. High-voltage circuits are especially vulnerable since the charged particles in smoke are drawn to those surfaces. To study failure probabilities, smoke exposure tests with real-time measurements will be carried out to determine how the electrical properties of the environment are affected by smoke concentration and content. Digital communication cable will be included in the tests because temporary shorts that cannot be detected through dc measurements may cause interruptions in communications between computers. The reaction of the equipment to changed electrical properties of the environment will be modeled. Equipment that can be used for testing and modeling is being solicited.

    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.

    A study was conducted to compare the effectiveness of the crib and positive reinforcement in eliminating anterior open bites and increased overjets caused by digit-sucking. The overjet and overbite were measured using an overjet ruler at the start and end of the seventeen-week observation period. Forty patients consented to participate but measurements were only obtained for 11 subjects. The trend in this study is that the crib is more effective than positive reinforcement in preventing digit-sucking.

    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.

    The purpose of this study was to explore the effects of case-based learning on communication skills, problem-solving ability, and learning motivation in sophomore nursing students. In this prospective, quasi-experimental study, we compared the pretest and post-test scores of an experimental group and a nonequivalent, nonsynchronized control group. Both groups were selected using convenience sampling, and consisted of students enrolled in a health communication course in the fall semesters of 2011 (control group) and 2012 (experimental group) at a nursing college in Suwon, South Korea. The two courses covered the same material, but in 2011 the course was lecture-based, while in 2012, lectures were replaced by case-based learning comprising five authentic cases of patient-nurse communication. At post-test, the case-based learning group showed significantly greater communication skills, problem-solving ability, and learning motivation than the lecture-based learning group. This finding suggests that case-based learning is an effective learning and teaching method.

    2009-07-01

    This paper describes a study in which Systemic Functional Linguistics was applied to describe how people who stutter use language. The aim of the study was to determine and describe any differences in language use between a group of 10 adults who stutter and 10 matched normally-fluent speakers. In addition to formal linguistic analyses, analyses drawn from Systemic Functional Linguistics were used to further investigate the expression of both syntactic and semantic complexity. The findings from this study replicated previous findings of Packman et al. in which they found that the language used by people who stutter was significantly less complex than the control group. Another major finding was that adults who stuttered used the linguistic resource of modality significantly less than the normally-fluent matched peers. The implications these strategies have on communication and social participation will be discussed.

    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

    Anthropogenic eutrophication affects the Mediterranean, Black, North and Baltic Seas to various extents. Responses to nutrient loading and methods of monitoring relevant indicators vary regionally, hindering interpretation of ecosystem state changes and preventing a straightforward pan-European assessment of eutrophication symptoms. Here we summarize responses to nutrient enrichment in Europe's seas, comparing existing time-series of selected pelagic (phytoplankton biomass and community composition, turbidity, N:P ratio) and benthic (macro flora and faunal communities, bottom oxygen condition) indicators based on their effectiveness in assessing eutrophication effects. Our results suggest that the Black Sea and Northern Adriatic appear to be recovering from eutrophication due to economic reorganization in the Black Sea catchment and nutrient abatement measures in the case of the Northern Adriatic. The Baltic is most strongly impacted by eutrophication due to its limited exchange and the prevalence of nutrient recycling. Eutrophication in the North Sea is primarily a coastal problem, but may be exacerbated by climatic changes. Indicator interpretation is strongly dependent on sea-specific knowledge of ecosystem characteristics, and no single indicator can be employed to adequately compare eutrophication state between European seas. Communicating eutrophication-related information to policy-makers could be facilitated through the use of consistent indicator selection and monitoring methodologies across European seas. This work is discussed in the context of the European Commission's recently published Marine Strategy Directive.

    The effect of airborne particles from diesel exhaust, rubber and metal industry, urban air and biological sources (poultry, pig farming, compost industry) on gap-junctional intercellular communication (GJIC) were compared, using HEPA1c1c7 cells. Particles as such were compared with aqueous and organic extracts. Significant inhibition of GJIC by particle suspensions was only observed for the diesel and rubber samples, and for one biological sample (compost). Up to 83% of the inhibition of the whole suspension could be attributed to the particles as such. Washing the particles with organic solvents (aceton, methanol, hexane) did not result in a significant loss of activity from the particles, although the organic fractions showed a significant activity towards GJIC. More active organics was eluted from the rubber industry particles than from the diesel particles by the organic solvent. It is suggested that cancer promoting potential as measured by inhibition of GJIC may vary widely depending on the particle source, and that this effect may be exerted by the particles as such and/or by means of tightly bound bio-active material to the surface.

    2002-05-01

    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.

    Aims The Center for Comparative Effectiveness Research in Cancer Genomics completed a 2-year stakeholder-guided process for the prioritization of genomic tests for comparative effectiveness research studies. We sought to evaluate the effectiveness of engagement procedures in achieving project goals and to identify opportunities for future improvements. Materials & methods The evaluation included an online questionnaire, one-on-one telephone interviews and facilitated discussion. Responses to the online questionnaire were tabulated for descriptive purposes, while transcripts from key informant interviews were analyzed using a directed content analysis approach. Results A total of 11 out of 13 stakeholders completed both the online questionnaire and interview process, while nine participated in the facilitated discussion. Eighty-nine percent of questionnaire items received overall ratings of agree or strongly agree; 11% of responses were rated as neutral with the exception of a single rating of disagreement with an item regarding the clarity of how stakeholder input was incorporated into project decisions. Recommendations for future improvement included developing standard recruitment practices, role descriptions and processes for improved communication with clinical and comparative effectiveness research investigators. Conclusions Evaluation of the stakeholder engagement process provided constructive feedback for future improvements and should be routinely conducted to ensure maximal effectiveness of stakeholder involvement.

    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.

    While FDA gathers vast amounts of data about prescription drugs prior to their marketing approval, important information about the relative effectiveness and long term safety of products is not required for approval, and often is never collected. Increased postmarket research on the safety and comparative effectiveness of products would improve medical decisionmaking and lead to better clinical outcomes. Fortunately, Congress has recognized the value of this information for healthcare professionals. In response to a congressional mandate in the FDA Amendments Act (FDAAA), FDA is developing the Sentinel Initiative, an active surveillance system for monitoring postmarket drug safety issues. FDAAA also authorized FDA to require a drug sponsor to conduct postmarket safety studies or clinical trials to address a specific safety concern. To increase the repository of comparative effectiveness information, Congress established the Patient-Centered Outcomes Research Institute (PCORI) in the Patient Protection and Affordable Care Act (PPACA), directing it to manage comparative effectiveness research (CER). This article discusses the need for better safety and comparative effectiveness information and outlines methods to efficiently conduct the research and communicate it effectively to healthcare professionals. Coordination between FDA and the PCORI in gathering and communicating postmarket information is recommended. Medical source data collected by the Sentinel Initiative should be used for CER in addition to postmarket safety surveillance, and FDA and the PCORI should adopt identical standards for the distribution and communication of CER. Coordination between the two entities is recommended to save costs, reduce duplication of efforts, and to generate and communicate more information on prescription drugs for medical decisionmakers.

  16. The effectiveness of mass communication to change public behavior.

    Abroms, Lorien C; Maibach, Edward W

    2008-01-01

    This article provides an overview of the ways in which mass communication has been used -- or can be used -- to promote beneficial changes in behavior among members of populations. We use an ecological perspective to examine the ways in which mass media interventions can be used to influence public behavior both directly and indirectly. Mass media interventions that seek to influence people directly -- by directly targeting the people burdened by the public health problem of concern and/or the people who influence them -- have a long basis in public health history, and recent reviews have clarified our expectations about what can be expected from such approaches. Mass media interventions that seek to influence people indirectly -- by creating beneficial changes in the places (or environments) in which people live and work -- have equal if not greater potential to promote beneficial changes in population health behaviors, but these are currently less explored options. To have the greatest possible beneficial influence on public behavior with the public health resources available, we recommend that public health program planners assess their opportunities to use media to target both people and places in a manner that complements and extends other investments being made in population health enhancement.

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

    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.

    1982-06-01

    Preschool children were paired in 12 speaker-listener dyads in which the speaker described common, familiar items and the listener attempted to guess their identity. Objects were presented until the listener had successfully guessed five objects and had missed five objects. Successfully guessed objects were conspicuously placed in an E-Z box whereas those missed were conspicuously placed in a HARD box. These 10 objects were then presented to the same team for identification once again, with each object being removed from the E-Z or HARD box with appropriate comments about its difficulty offered by the experimenter. Postfeedback, the speakers used longer and more informative descriptions for items that had originally been failed, and shorter, less informative descriptions for those that had been successfully guessed on the first identification trials. The changes in the form of the messages for the success items were somewhat greater than for the failure items, suggesting that children might not have mastered specific strategies for composing maximally useful messages, even when the children were disposed to respond to listener communicative needs.

    1986-01-01

    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.

    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.

    PubMed Central

    Hardee, James T; Kasper, Ilene K

    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

  3. Effective communication about the use of complementary and integrative medicine in cancer care.

    PubMed

    Frenkel, Moshe; Cohen, Lorenzo

    2014-01-01

    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.

    Comparative effectiveness research includes cohort studies and registries of interventions. When investigators design such studies, how important is it to follow patients from the day they initiated treatment with the study interventions? Our article considers this question and related issues to start a dialogue on the value of the incident user design in comparative effectiveness research. By incident user design, we mean a study that sets the cohort's inception date according to patients' new use of an intervention. In contrast, most epidemiologic studies enroll patients who were currently or recently using an intervention when follow-up began. We take the incident user design as a reasonable default strategy because it reduces biases that can impact non-randomized studies, especially when investigators use healthcare databases. We review case studies where investigators have explored the consequences of designing a cohort study by restricting to incident users, but most of the discussion has been informed by expert opinion, not by systematic evidence.

    2013-01-01

    CER for heart failure continues to evolve, including its assessment of end points. Reliance on surrogate end points is unacceptable as a means of definitively establishing comparisons of clinical effectiveness. CER needs to focus on measures that clearly reflect clinical effectiveness and safety, not just survival but also standardized assessments of health status and detailed resource utilization, and it must do so in a standardized way to allow for comparison. This strategy almost certainly requires increased reliance on prospective studies with proactive end-point capture, preferably in the setting of randomized allocation of the interventions being compared.

    Objectives. To launch and evaluate a comparative effectiveness research education and dissemination program as part of an introductory pharmacy practice experience (IPPE). Methods. First- through third-year PharmD students received training on comparative effectiveness research and disseminated printed educational materials to patients in the community who they were monitoring longitudinally (n=314). Students completed an assessment and initial visit documentation form at the first visit, and a follow-up assessment and documentation form at a subsequent visit. Results. Twenty-three diabetes patients, 29 acid-reflux patients, 30 osteoarthritis patients, and 50 hypertension patients received materials. Aside from the patient asking questions, which was the most common outcome (n=44), the program resulted in 38 additional actions, which included stopping, starting, or changing treatments or health behaviors, or having additional follow-up or diagnostic testing. Small but positive improvements in patient understanding, confidence, and self-efficacy were observed. Conclusions. Dissemination of comparative effectiveness research materials in an IPPE program demonstrated a positive trend in markers of informed decision-making. PMID:28289299

  9. "Lies, damned lies ..." and observational studies in comparative effectiveness research.

    PubMed

    Albert, Richard K

    2013-06-01

    A new federal initiative has allocated $1.1 billion to comparative effectiveness research, and many have emphasized the importance of including observational studies in this effort. The rationale for using observational studies to assess comparative effectiveness is based on concerns that randomized controlled trials (RCTs) are not "real world" because they enroll homogeneous patient populations, measure study outcomes that are not important to patients, use protocols that are overly complex, are conducted in specialized centers, and use study treatments that are not consistent with usual care, and that RCTs are not always feasible because of a lack of equipoise, the need to assess delayed endpoints, and concerns that they take years to complete and are expensive. This essay questions the validity of each of these proposed limitations, summarizes concerns raised about the accuracy of results generated by observational studies, provides some examples of discrepancies between results of observational studies and RCTs that pertain to pulmonary and critical care, and suggests that using observational studies for comparative effectiveness research may increase rather than decrease the cost of health care and may harm patients.

    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.

    Objective To perform a population-based analysis to compare the complications and cost of laparoscopic and robotically assisted adnexal surgery. Methods A nationwide database was utilized to analyze the use and outcomes of robotically assisted adnexal surgery from 2009–2012. Multivariable mixed effects regression models were developed to examine predictors of use of robotic surgery. After propensity score matching, complications and cost were compared between robotically assisted and laparoscopic surgery. Results 87,514 women were identified. From 2009 to 2012, performance of robotic-assisted oophorectomy increased from 3.5% (95% CI, 3.2–3.8%) to 15.0% (95% CI, 14.4–15.6%), while robotically assisted cystectomy rose from 2.4% (95% CI, 2.0–2.7%) to 12.9% (95% CI, 12.2–13.5%). The overall complication rate was 7.1% (95% CI, 4.0–10.2%) for robotically assisted vs. 6.0% (95% CI, 2.9–9.1%) for laparoscopic oophorectomy (OR=1.20; 95% CI, 1.00–1.45) (P=0.052). Robotic-assisted oophorectomy was associated with a higher rate of intraoperative complications (3.4% vs. 2.1%, OR=1.60; 95% CI, 1.21–2.13). The overall complication rate was 3.7% (95% CI −0.8–8.2%) after robotically assisted versus 2.7% (95% CI, −1.8–7.2%) for laparoscopic cystectomy (OR=1.38; 95% CI, 0.95–1.99). The intraoperative complication rate was higher for robotically assisted cystectomy (2.0% vs. 0.9%, OR=2.40; 95% CI, 1.31–4.38). Compared to laparoscopy, robotically assisted oophorectomy was associated with $2504 (95% CI, $2356–$2652) increased total costs and robotically assisted cystectomy $3310 (95% CI, $3082–$3581) higher costs. Conclusion Use of robotically assisted adnexal surgery increased rapidly. Compared to laparoscopic surgery, robotically assisted adnexal surgery is associated with substantially greater costs and a small, but statistically significant, increase in intraoperative complications.

    2009-03-01

    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.

    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.

    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.

    2008-11-01

    Recent reports provide cogent evidence that the average individual becomes chromium deficient with age. Unfortunately, chromium deficiency is strongly associated with many aspects of the Metabolic Syndrome, including insulin resistance and type 2 diabetes. Since replacement of chromium, per os, often ameliorates many deleterious manifestations associated with insulin resistance and diabetes, it is not surprising that many different, commercial trivalent chromium compounds are available on the market. However, previous reports have shown that the form of trivalent chromium (negative charges) can influence effectiveness markedly. We compared various commercial forms of trivalent chromium commonly used alone or in formulations, to examine whether they are equally effective and non-toxic. In the first study, five different chromium products were examined - citrate, amino acid chelate (AAC), chelavite, polynicotinate (NBC), and nicotinate. In the second study, effects of NBC and picolinate were assessed. Results demonstrated that only chelavite and NBC improved insulin sensitivity, and only NBC decreased systolic blood pressure (SBP) significantly. In the second study, both picolinate and NBC significantly decreased SBP compared to control. NBC and picolinate decreased malonyldialdehyde concentrations (free radical formation) and DNA fragmentation in hepatic and renal tissues. No evidence of adverse effects was noted with any of the compounds tested. In conclusion, while all the trivalent chromium compounds tested seem safe, only three enhanced insulin sensitivity (NBC, chelavite, and picolinate) and only two decreased SBP significantly (NBC and picolinate). Furthermore, both NBC and picolinate were protective in lessening free radical formation and DNA damage in the liver and kidneys.

    Objective: To identify high-priority comparative effectiveness questions directly relevant to care delivery in a large, US integrated health care system. Methods: In 2010, a total of 792 clinical and operational leaders in Kaiser Permanente were sent an electronic survey requesting nominations of comparative effectiveness research questions; most recipients (83%) had direct clinical roles. Nominated questions were divided into 18 surveys of related topics that included 9 to 23 questions for prioritization. The next year, 648 recipients were electronically sent 1 of the 18 surveys to prioritize nominated questions. Surveys were assigned to recipients on the basis of their nominations or specialty. High-priority questions were identified by comparing the frequency a question was selected to an “expected” frequency, calculated to account for the varying number of questions and respondents across prioritization surveys. High-priority questions were those selected more frequently than expected. Results: More than 320 research questions were nominated from 181 individuals. Questions most frequently addressed cardiovascular and peripheral vascular disease; obesity, diabetes, endocrinology, and metabolic disorders; or service delivery and systems-level questions. Ninety-five high-priority research questions were identified, encompassing a wide range of health questions that ranged from prevention and screening to treatment and quality of life. Many were complex questions from a systems perspective regarding how to deliver the best care. Conclusions: The 95 questions identified and prioritized by leaders on the front lines of health care delivery may inform the national discussion regarding comparative effectiveness research. Additionally, our experience provides insight in engaging real-world stakeholders in setting a health care research agenda. PMID:24361013

    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.

    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.

    Numerous steroids are now believed to possess rapid membrane effects independent of the classical gene activation pathways and are potent modulators of membrane proteins, including voltage-and ligand-operated channels. The effects of steroids on the functional state of the intercellular channels clustered in gap junctions were compared by estimation of either the permeability for a fluorescent dye or the electrical conductance in cardiac myocytes of newborn rat. At 25 muM, the esters of 17beta-estradiol, testosterone and two other androgen hormones rapidly abolished cell-to-cell communication, whereas none of the longer chain steroids, belonging to pregnane (17alpha-hydroxypregnenolone, hydrocortisone), sterol (cholesterol, 25-hydroxycholesterol), bile acid (cholic and lithocholic acids) and vitamin (D3) families, lowered the junctional permeability. Altogether, no correlation with the presence or position of double bonds nor with the trans- or cis-fusion of the A and B rings was recognized. Esterification was a prerequisite for the activity of extracellularly applied steroids but the number, nature and position of ester chain(s) had no influence. 17beta-estradiol or testosterone effects were not prevented when cells were prein-cubated with blockers of the estrogen or androgen nuclear receptors (tamoxifen and cyproterone acetate, respectively). This, together with the rapid time course of the steroid effect (complete within a few minutes), in a rather high active concentration range, suggests a nongenomic mechanism of action. The reversible uncoupling effect of steroids appears to be independent of the shape of the molecules and more probably related to their size and lipo-solubility, which condition their insertion into the lipid bilayer and their subsequent disturbing effects.

    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.

    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.

    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 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.

    The appearance of gap junctions (GJs) between myometrial smooth muscle cells is one of the major events associated with the onset of labor. We have employed dye-coupling and electrical-current injection techniques to study the mechanisms by which steroid hormones regulate GJs in term pregnant myometrium of women before labor. Progesterone (P4) did not alter the input resistance (Ro) of the tissues when added to Tyrode's solution, which was used as control treatment. Octanol, the putative gap junctional uncoupling agent, increased the Ro of the cells compared to the control and P4-treated groups. The membrane potential (Em) did not differ between these groups. However, when P4 was applied after the tissue was perfused with estradiol (E2), the results changed dramatically: the Em hyperpolarized, and the Ro increased. Octanol increased the Ro in E2-treated tissues, but did not affect the Em. Consecutive application of E2, octanol, E2, and P4 resulted in rapid changes in the Ro of the cells. Dye-coupling was mostly detected between cells from controls and E2-treated tissues. These results indicate that P4 exerts its effects in the presence of E2 and that P4 has rapid effects on the intercellular communication between human myometrial cells.

    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.

    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.

    Objective Psychopharmacology remains the foundation of treatment for bipolar disorder, but medication adherence in this population is low (Range = 20% to 64%). We examined medication adherence in a multi-site, comparative effectiveness study of lithium. Method The Lithium Moderate Dose Use Study (LiTMUS) was a six-month, six-site, randomized effectiveness trial of adjunctive moderate dose lithium therapy compared to optimized treatment in adult outpatients with bipolar I or II disorder (N=283). Medication adherence was measured at each study visit with the Tablet Routine Questionnaire. Results We found that 4.50% of participants reported missing at least 30% of their medications in the past week at baseline and non-adherence remained low throughout the trial (< 7%). Poor medication adherence was associated with more manic symptoms and side effects as well as lower lithium serum levels at mid- and post-treatment, but not with poor quality of life, overall severity of illness, or depressive symptoms. Conclusion Participants in LiTMUS were highly adherent with taking their medications. The lack of association with possible predictors of adherence, such as depression and quality of life, could be explained by the limited variance or other factors as well as by not using an objective measure of adherence.

    Physicians and insurers need to weigh the effectiveness of new drugs against existing therapeutics in routine care to make decisions about treatment and formularies. Because Food and Drug Administration (FDA) approval of most new drugs requires demonstrating efficacy and safety against placebo, there is limited interest by manufacturers in conducting such head-to-head trials. Comparative effectiveness research seeks to provide head-to-head comparisons of treatment outcomes in routine care. Health-care utilization databases record drug use and selected health outcomes for large populations in a timely way and reflect routine care, and therefore may be the preferred data source for comparative effectiveness research. Confounding caused by selective prescribing based on indication, severity, and prognosis threatens the validity of non-randomized database studies that often have limited details on clinical information. Several recent developments may bring the field closer to acceptable validity, including approaches that exploit the concepts of proxy variables using high-dimensional propensity scores, within-patient variation of drug exposure using crossover designs, and between-provider variation in prescribing preference using instrumental variable (IV) analyses.

    Unlike other drugs which act in the region of the synapse, local anesthetics are agents that reversibly block the generation and conduction of nerve impulses along a nerve fiber. This study aims to investigate the comparative inhibitions of bupivacaine and ropivacaine on the frog sciatic nerve. Isolated nerves were transferred to the nerve chamber which includes Ringer's solution. The nerves were stimulated by standard square wave pulse protocols and the responses were recorded with conventional systems. Bupivacaine (n = 8) and ropivacaine (n = 8) were administered in the nerve chamber bath with cumulative concentrations (10(-9) to 10(-3) M) and the effects were monitored for variable time periods (5, 10 and 15 min). Both bupivacaine and ropivacaine significantly depressed the compound action potential (CAP) parameters in a dose-dependent (p < 0.05) and reversible manner. Difference in the effects of these two drugs was detectable only when the dose (> or =10(-5) M) and exposure time (15 min) were increased. Percent inhibitions in maximum derivatives and latency-period measurements have shown that ropivacaine is not only fast but also much more powerful in conduction block for longer and higher doses. Bupivacaine, on the other hand, is effective in the group of fibers with relatively slower conduction velocity for all the measured doses and time periods. In conclusion, ropivacaine has a sensory specific side of action, when compared with the bupivacaine.

    Successful anti-marijuana messages can be hypothesized to have two types of effects, namely persuasion effects, that is, a change in people’s beliefs about using marijuana, and priming effects, that is, a strengthened correlation between beliefs and associated variables such as attitude and intention. This study examined different sets of anti-drug advertisements for persuasion and priming effects. The ads targeted the belief that marijuana is a gateway to stronger drugs, a belief that is often endorsed by campaign planning officials and health educators. A sample of 418 middle and high school students was randomly assigned to a control video or one of three series of ads, two of which included the gateway message in either an explicit or implicit way. Results did not support the use of the gateway belief in anti-marijuana interventions. Whereas no clear persuasion or priming effects were found for any of the ad sequences, there is some possibility that an explicit gateway argument may actually boomerang. In comparison to the control condition, adolescents in the explicit gateway condition tended to agree less with the gateway message and displayed weaker correlations between anti-marijuana beliefs and their attitude toward marijuana use. The results suggest that the gateway message should not be used in anti-drug interventions. PMID:12746037

    Physician-patient communication is a clinical skill that can be learned and has a positive impact on patient satisfaction and health outcomes. A concerted effort at all medical schools is now directed at teaching and evaluating this core skill. Student communication skills are often assessed by an Objective Structure Clinical Examination (OSCE). However, it is unknown what sources of error variance are introduced into examinee communication scores by various OSCE components. This study primarily examined the effect different examiners had on the evaluation of students' communication skills assessed at the end of a family medicine clerkship rotation. The communication performance of clinical clerks from Classes 2005 and 2006 were assessed using six OSCE stations. Performance was rated at each station using the 28-item Calgary-Cambridge guide. Item Response Theory analysis using a Multifaceted Rasch model was used to partition the various sources of error variance and generate a "true" communication score where the effects of examiner, case, and items are removed. Variance and reliability of scores were as follows: communication scores (.20 and .87), examiner stringency/leniency (.86 and .91), case (.03 and .96), and item (.86 and .99), respectively. All facet scores were reliable (.87-.99). Examiner variance (.86) was more than four times the examinee variance (.20). About 11% of the clerks' outcome status shifted using "true" rather than observed/raw scores. There was large variability in examinee scores due to variation in examiner stringency/leniency behaviors that may impact pass-fail decisions. Exploring the benefits of examiner training and employing "true" scores generated using Item Response Theory analyses prior to making pass/fail decisions are recommended.

    A systematic expansion of the many-body master equation for active matter, in which motors power configurational changes as in the cytoskeleton, is shown to yield a description of the steady state and responses in terms of an effective temperature. The effective temperature depends on the susceptibility of the motors and a Peclet number which measures their strength relative to thermal Brownian diffusion. The analytic prediction is shown to agree with previous numerical simulations and experiments. The mapping also establishes a description of aging in active matter that is also kinetically jammed.

    It is widely known that gaze plays an essential role in communicative interactions. Domestic dogs tend to look at the human face in situations of conflict and uncertainty. This study compares the gaze of shelter and pet dogs during acquisition and extinction phases in a situation involving a reward in sight but out of reach. Even though no significant differences between the groups were recorded during acquisition, gaze duration decreased in both groups during extinction, with shelter dogs showing a significant shorter duration. This could be related to their different living conditions and to the fact that through their ordinary everyday interactions, pet dogs have more opportunities to learn to persist in their communicative responses when they do not get what they want. These results highlight the relevance of learning experiences during ontogeny, which would therefore modulate communicative responses.

    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.

    Communication is the act of information transfer between sender and receiver. In rats, vocal communication can be studied through ultrasonic vocalizations (USV). 50-kHz USV occur in appetitive situations, most notably juvenile play, likely expressing the sender׳s positive affective state. Such appetitive 50-kHz USV serve important pro-social communicative functions and elicit social exploratory and approach behavior in the receiver. Emission of 50-kHz USV can be induced pharmacologically by the administration of psychostimulant drugs, such as amphetamine. However, it is unknown whether amphetamine affects the pro-social communicative function of 50-kHz USV in the receiver. We therefore assessed dose-response effects of amphetamine (0.0mg/kg, 0.5mg/kg, 1.0mg/kg, 2.5mg/kg, 5.0mg/kg) on pro-social ultrasonic communication on both, sender and receiver, in juvenile rats. We found an inverted U-shaped effect of amphetamine on 50-kHz USV emission, with 50-kHz USV levels being strongly enhanced by moderate doses, yet less prominent effects were seen following the highest dose. Likewise, amphetamine exerted inverted U-shaped effects on social exploratory and approach behavior induced by playback of appetitive 50-kHz USV. Social approach was enhanced by moderate amphetamine doses, but completely abolished following the highest dose. Amphetamine further dose-dependently promoted the emission of 50-kHz USV following playback of appetitive 50-kHz USV, indicating more vigorous attempts to establish social proximity. Our results support an important role of dopamine in closing a perception-and-action-loop through linking mechanisms relevant for detection and production of social vocalizations. Moreover, our approach possibly provides a new means to study mania-like aberrant social interaction and communication in animal models for bipolar disorder.

  12. The effect of limited cognitive resources on communication disturbances in serious mental illness.

    2017-02-01

    Semantically incoherent speech is a pernicious clinical feature of serious mental illness (SMI). The precise mechanisms underlying this deficit remain unclear. Prior studies have found that arousal of negative emotion exaggerates the severity of these communication disturbances; this has been coined "affective reactivity". Recent research suggests that "cognitive reactivity" may also occur, namely reflecting reduced "on-line" cognitive resources in SMI. We tested the hypothesis that communication disturbances manifest as a function of limited cognitive resources in SMI above and beyond that associated with state affectivity. We also investigated individual differences in symptoms, cognitive ability, and trait affect that may be related to cognitive reactivity. We compared individuals with SMI (n=52) to nonpsychiatric controls (n=27) on a behavioral-based coding of communication disturbances during separate baseline and experimentally-manipulated high cognitive-load dual tasks. Controlling for state affective reactivity, a significant interaction was observed such that communication disturbances decreased in the SMI group under high cognitive-load. Furthermore, a reduction in communication disturbances was related to lower trait and state positive affectivity in the SMI group. Contrary to our expectations, limited cognitive resources temporarily relieved language dysfunction. Implications, particularly with respect to interventions, are discussed.

    Effective communication by nursing home staff is related to a higher quality of life and a decrease in verbal and physical aggression and depression in nursing home residents. Several communication intervention studies have been conducted to improve communication between nursing home staff and nursing home residents with dementia. These studies have shown that communication skills training can improve nursing aides’ communication with nursing home residents. However, these studies tended to be time-consuming and fairly difficult to implement. Moreover, these studies focused on the communicative benefits for the nursing home residents and their well-being, while benefits and well-being for the nursing aides were neglected. The current study focused on implementing a brief communication skills training program to improve nursing aides’ (N=24) communication with residents with dementia (N=26) in a nursing home. The effects of the training on nursing aides’ communication, caregiver distress, and job satisfaction and residents’ psychopathology and agitation were assessed relative to a control group condition. Nursing aides in the intervention group were individually trained to communicate effectively with residents during morning care by using short instructions, positive speech, and biographical statements. Mixed ANOVAs showed that, after training, nursing aides in the intervention group experienced less caregiver distress. Additionally, the number of short instructions and instances of positive speech increased. Providing nursing aides with helpful feedback during care aids communication and reduces caregiver burden, even with a brief intervention that requires limited time investments for nursing home staff.

    We review recent empirical evidence that shows political campaigns are more potent than widely believed, focusing on the conceptual and methodological advances that have produced these findings. Conceptually, a broader definition of effects--that includes learning and agenda-control, as well as vote choice--characterizes contemporary research. This research also features two kinds of interactive models that are more complex than the traditional hypodermic (message-based) approach. The resonance model considers the relationship between message content and receivers' predispositions, while the strategic model highlights the interactions between competing messages. Finally, we attribute the emergence of stronger evidence in favor of campaign effects to the use of new methodologies including experimentation and content analysis, as well as the more sophisticated use of sample surveys.

    2010-08-30

    Comparative effectiveness research (CER) has received substantial attention as a potential approach for improving health outcomes while lowering costs of care, and for improving the relevance and quality of clinical and health services research. The Institute of Medicine defines CER as 'the conduct and synthesis of systematic research comparing different interventions and strategies to prevent, diagnose, treat, and monitor health conditions. The purpose of this research is to inform patients, providers, and decision-makers, responding to their expressed needs, about which interventions are most effective for which patients under specific circumstances.' Improving the methods and infrastructure for CER will require sustained attention to the following issues: (1) Meaningful involvement of patients, consumers, clinicians, payers, and policymakers in key phases of CER study design and implementation; (2) Development of methodological 'best practices' for the design of CER studies that reflect decision-maker needs and balance internal validity with relevance, feasibility and timeliness; and (3) Improvements in research infrastructure to enhance the validity and efficiency with which CER studies are implemented. The approach to addressing each of these issues should be informed by the understanding that the primary purpose of CER is to help health care decision makers make informed clinical and health policy decisions.

  19. Distinguishing Selection Bias and Confounding Bias in Comparative Effectiveness Research.

    PubMed

    Haneuse, Sebastien

    2016-04-01

    Comparative effectiveness research (CER) aims to provide patients and physicians with evidence-based guidance on treatment decisions. As researchers conduct CER they face myriad challenges. Although inadequate control of confounding is the most-often cited source of potential bias, selection bias that arises when patients are differentially excluded from analyses is a distinct phenomenon with distinct consequences: confounding bias compromises internal validity, whereas selection bias compromises external validity. Despite this distinction, however, the label "treatment-selection bias" is being used in the CER literature to denote the phenomenon of confounding bias. Motivated by an ongoing study of treatment choice for depression on weight change over time, this paper formally distinguishes selection and confounding bias in CER. By formally distinguishing selection and confounding bias, this paper clarifies important scientific, design, and analysis issues relevant to ensuring validity. First is that the 2 types of biases may arise simultaneously in any given study; even if confounding bias is completely controlled, a study may nevertheless suffer from selection bias so that the results are not generalizable to the patient population of interest. Second is that the statistical methods used to mitigate the 2 biases are themselves distinct; methods developed to control one type of bias should not be expected to address the other. Finally, the control of selection and confounding bias will often require distinct covariate information. Consequently, as researchers plan future studies of comparative effectiveness, care must be taken to ensure that all data elements relevant to both confounding and selection bias are collected.

  20. Comparative effectiveness of correction strategies in connected discourse tracking.

    1994-10-01

    The effectiveness of four correction strategies commonly used in connected discourse tracking was investigated in the present study. The strategies were 1) verbatim repetition of a word or phrase; 2) use of antonyms or synonyms as cues; 3) use of phonemic cues, with no whole word repetition; and 4) going back or ahead in the text, with no repetition of the missed segment. Four normal-hearing adults served as listeners. Live-voice presentation of text by two female talkers was employed for all conditions. Listeners were tested in two stimulus presentation modes, speechreading alone and speechreading plus a multichannel tactile aid. Results indicated that strategy 1, repetition of the missed segment, produced the highest tracking rates, significantly higher than any of the other strategies. Strategy 2 produced the lowest tracking rates. Strategies 1 and 3 yielded the lowest percentage of initially missed words, or blockages, and strategy 4 the highest percentage. Significantly higher tracking rates were found under the speechreading plus tactile aid presentation mode, compared with speechreading alone. Further, tracking rates increased significantly from the beginning to the end of training. Data were compared with a more typical CDT task, in which all correction strategies were operative, and results showed little difference in tracking rates between this task and the constrained CDT employing only strategy 1. Overall, results suggest that simple repetition of missed segments is an effective correction strategy for CDT and argue for its inclusion in computer-assisted tracking implementations.

  1. The 'go-between' study: a simulation study comparing the 'Traffic Lights' and 'SBAR' tools as a means of communication between anaesthetic staff.

    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.

    The objectives of this study were to evaluate the effectiveness of corporate communication activities carried out during the A(H1N1) pandemic influenza in Italy and to identify educational needs of health professionals with regards to crisis communication. The study compared two samples representing respectively the general population and health professionals, living in different regions of northern, central and southern Italy. A self-administered questionnaire was used, with questions on knowledge about preventive measures during a pandemic and on satisfaction with the adopted communication campaigns. Study results highlight that both samples had very little knowledge of appropriate preventive behaviors to be adopted during a pandemic. The sample of health professionals received a greater amount of information about the pandemic with respect to the general population and showed a strong interest toward the problem of receiving adequate training in risk communication. The degree of knowledge about preventive measures is directly proportional to the existence of institutional communication activities and to having consulted a health professional.

  4. 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.

    2008-01-01

    Effective communication and teamwork have been identified in the literature as key enablers of patient safety. The SBAR (Situation-Background-Assessment-Recommendation) process has proven to be an effective communication tool in acute care settings to structure high-urgency communications, particularly between physicians and nurses; however, little is known of its effectiveness in other settings. This study evaluated the effectiveness of an adapted SBAR tool for both urgent and non-urgent situations within a rehabilitation setting. In phase 1 of this study, clinical staff, patient and family input was gathered in a focus-group format to help guide, validate and refine adaptations to the SBAR tool. In phase 2, the adapted SBAR was implemented in one interprofessional team; clinical and support staff participated in educational workshops with experiential learning to enhance their proficiency in using the SBAR process. Key champions reinforced its use within the team. In phase 3, evaluation of the effectiveness of the adapted SBAR tool focused on three main areas: staff perceptions of team communication and patient safety culture (as measured by the Agency for Healthcare Research and Quality Hospital Survey on Patient Safety Culture), patient satisfaction (as determined using the Client Perspectives on Rehabilitation Services questionnaire) and safety reporting (including incident and near-miss reporting). Findings from this study suggest that staff found the use of the adapted SBAR tool helpful in both individual and team communications, which ultimately affected perceived changes in the safety culture of the study team. There was a positive but not significant impact on patient satisfaction, likely due to a ceiling effect. Improvements were also seen in safety reporting of incidents and near misses across the organization and within the study team.

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

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

    2016-02-14

    We present results of ring polymer molecular dynamics simulations that shed light on the effects of nuclear quantum fluctuations on tunneling motions in cyclic [H{sub 2}O]{sub 3} and [D{sub 2}O]{sub 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 [H{sub 2}O]{sub 3} than in [D{sub 2}O]{sub 3}. Estimates of the characteristic time scales describing the flipping transitions are consistent with those predicted based on standard transition-state-approximation arguments.

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.

    Specific ion effects in solvation processes are often rationalized in terms of spherically symmetric models involving an ion’s size, charge, and polarizability. The effects of permanent charge anisotropy, related to the polyatomic nature of complex solutes, are expected to play a role in solvation but the extent of their importance remains unexplored. In this work we provide compelling experimental and theoretical evidence that the anisotropic nature of complex polyoxyanion solutes can have a critical influence on the solvation process. Combined photoelectron spectroscopy and theoretical modeling results show that the electron binding energy (EBE) of IO3-(H2O)n (n = 0 - 12) clusters is characterized by an anomalous drop at n = 10. Such behavior is unprecedented for rigid solute molecules, and is related to the anisotropy of the neutral iodate radical that displays a strong selectivity to solvent configurations generated by the charged anion complex. These results highlight the significance of solute anisotropy and its potential impact on ion specificity and selectivity in aqueous environments.

    This report presents the plan for the characterization of the effects of high intensity radiated fields on a prototype implementation of a fault-tolerant data communication system. Various configurations of the communication system will be tested. The prototype system is implemented using off-the-shelf devices. The system will be tested in a closed-loop configuration with extensive real-time monitoring. This test is intended to generate data suitable for the design of avionics health management systems, as well as redundancy management mechanisms and policies for robust distributed processing architectures.

    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.

    Informed consent is fundamental to the protection of the rights, safety and wellbeing of patients in clinical research. For consent to be valid, patients must first be given all the information they need about the proposed research to be able to decide whether they would like to take part. This material should be presented in a way that is easy for them to understand. This article explores the importance of communication in clinical research, and how more effective communication with patients during the informed consent process can ensure they are fully informed.

    Adaptive optics (AO) systems can suppress the signal fade induced by atmospheric turbulence in satellite-to-ground coherent optical communication. The lower bound of the signal fade under AO compensation was investigated by analyzing the pattern of aberration modes for a one-stage imaging AO system. The distribution of the root mean square of the residual aberration is discussed on the basis of the spatial and temporal characteristics of the residual aberration of the AO system. The effectiveness of the AO system for improving the performance of coherent optical communication is presented in terms of the bit error rate and system availability.

  19. On the origins of human handedness and language: a comparative review of hand preferences for bimanual coordinated actions and gestural communication in nonhuman primates.

    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.

    Abstract Background  The Institute of Medicine recently recommended that comparative effectiveness research (CER) should involve input from consumers. While systematic reviews are a major component of CER, little is known about consumer involvement. Objective  To explore current approaches to involving consumers in US‐based and key international organizations and groups conducting or commissioning systematic reviews (‘organizations’). Design  In‐depth, semi‐structured interviews with key informants and review of organizations’ websites. Setting and participants  Seventeen highly regarded US‐based and international (Cochrane Collaboration, Campbell Collaboration) organizations. Results  Organizations that usually involve consumers (seven of 17 in our sample) involve them at a programmatic level in the organization or in individual reviews through one‐time consultation or on‐going collaboration. For example, consumers may suggest topics, provide input on the key questions of the review, provide comments on draft protocols and reports, serve as co‐authors or on an advisory group. Organizations involve different types of consumers (individual patients, consumer advocates, families and caregivers), recruiting them mainly through patient organizations and consumer networks. Some offer training in research methods, and one developed training for researchers on how to involve consumers. Little formal evaluation of the effects of consumer involvement is being carried out. Conclusions  Consumers are currently involved in systematic reviews in a variety of ways and for various reasons. Assessing which approaches are most effective in achieving different aims of consumer involvement is now required to inform future recommendations on consumer involvement in CER. PMID:22390732

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

    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

    The effects of four isomers of dinitrotoluene (DNT) and technical DNT (a mixture of DNT isomers and other compounds, with 2,4-DNT as the major constituent) were studied in two short-term in vitro assays. None of the isomers or technical DNT induced an increase in morphological transformation of Syrian hamster embryo (SHE) cells. Four DNT metabolites (2,4-diaminotoluene, 2-amino-4-nitrotoluene, 2-amino-6-nitrotoluene, and 2,4-dinitobenzoic acid), representing different stages in reduction or oxidation of DNT isomers, were also negative for induction of morphological transformation. The DNT isomers were tested in an intercellular communication assay based on dye transfer. 2,4-DNT, 2,6-DNT, and technical DNT inhibited intercellular communication in the SHE cell line BPNi at toxic concentrations. This may be reminiscent of in vivo data showing promoting activity of these compound. 2,3-DNT and 3,4-DNT did not inhibit communication.

    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.

    This article reviews experiments completed over the past decade at the National Technical Institute for the Deaf and the State University of New York at Geneseo concerning speech produced during simultaneous communication (SC) and synthesizes the empirical evidence concerning the acoustical and perceptual characteristics of speech in SC. Comparisons are drawn between SC and other modes of rate-altered speech that have been used successfully to enhance communication effectiveness. Of particular importance are conclusions regarding the appropriateness of speech produced during SC for communication between hearing and hearing-impaired speakers and listeners and the appropriateness of SC use by parents and teachers for speech development of children with hearing impairment. This program of systematic basic research adds value to the discussion about the use of SC by focusing on the specific implications of empirical results regarding speech production and perception.

    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.

    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.

    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.

    This study examined the effects of computer-assisted communication on team decision-making performance as a function of the team's openness to experience. Seventy-nine teams performing a multiple-cue probability learning task were randomly assigned to 1 of 2 experimental conditions: (a) verbal communication or (b) computer-assisted communication (which combined verbal and computerized communication). The results indicated that access to computer-assisted communication improved the decision-making performance of teams, but only when the teams were high in openness to experience. This effect was observed using both global openness and more specific openness facets, as well as a variety of team-level aggregation strategies. Moreover, the beneficial effects of openness in computer-assisted conditions were mediated by the efficiency with which teams integrated verbal and computerized forms of communication.

    Faced with the growing frequency of mental disorders occurrence and considering the necessity of improving the patient care, it is particularly important that physicians of different specialties knew the general principles of effective communication with patients who are mentally ill. Equally important is to spread the knowledge of the symptomatology of various mental illnesses. Studies published by the Institute of Psychiatry and Neurology involving persons between 18 and 64 years old, show that 8 millions Poles suffers or suffered from mental disorders. This represents almost 25% of Polish society. The above data confirm, that basic knowledge of criteria for diagnosing mental disorders and their treatment by primary care physicians, determines the success of the entire health care system. It must be taken into consideration that frequently patients seeing general practitioner (GP) are suffering from more than one mental illness or it is accompanied by somatic disease. Adequate communication determines effective treatment. Simple yet exact message, ability to adapt it to patient and problems reported by him, is a valuable means in daily medical practice. It reduces the risk of iatrogenic disorder, encourages the efficiency of the entire therapeutic process. Good cooperation with the patient is also determined by patience, empathy, understanding, and competence. The aim of this study is to present the principles of effective communication between doctor and patient suffering from selected mental disorders. The article defines the concept of communication. It shows symptomatology of primary psychiatric disorders. Moreover, the most common difficulties in relationship between the doctor and the patient had been pointed.

    Comparative effectiveness research (CER) is a broad category of outcomes research encompassing many different methods employed by researchers and clinicians from numerous disciplines. The goal of cancer-focused CER is to generate new knowledge to assist cancer stakeholders in making informed decisions that will improve health care and outcomes of both individuals and populations. There are numerous CER methods that may be used to examine specific questions, including randomized controlled trials, observational studies, systematic literature reviews, and decision sciences modeling. Each has its strengths and weaknesses. To both inform and serve as a reference for readers of this issue of Seminars in Radiation Oncology as well as the broader oncology community, we describe CER and several of the more commonly used approaches and analytical methods.

    Before introducing a hospital-wide image database to improve access, navigation and retrieval speed, a comparative study between a conventional slide library and a matching image database was undertaken to assess its relative benefits. Paired time trials and personal questionnaires revealed faster retrieval rates, higher image quality, and easier viewing for the pilot digital image database. Analysis of confidentiality, copyright and data protection exposed similar issues for both systems, thus concluding that the digital image database is a more effective library system. The authors suggest that in the future, medical images will be stored on large, professionally administered, centrally located file servers, allowing specialist image libraries to be tailored locally for individual users. The further integration of the database with web technology will enable cheap and efficient remote access for a wide range of users.

    Patients, providers and policy-makers rely heavily on comparative effectiveness research (CER) when making complex, real-world medical decisions. In particular, Medicaid providers and policy-makers face unique challenges in decision-making because their program cares for traditionally underserved populations, especially children, pregnant women and people with mental illness. Because these patient populations have generally been underrepresented in research discussions, CER questions for these groups may be understudied. To address this problem, the Agency for Healthcare Research and Quality commissioned our team to work with Medicaid Medical Directors and other stakeholders to identify relevant CER questions. Through an iterative process of topic identification and refinement, we developed relevant, feasible and actionable questions based on issues affecting Medicaid programs nationwide. We describe challenges and limitations and provide recommendations for future stakeholder engagement.

    Clinical research needs to be more useful to patients, clinicians, and other decision makers. To meet this need, more research should focus on patient-centered outcomes, compare viable alternatives, and be responsive to individual patients' preferences, needs, pathobiology, settings, and values. These features, which make comparative effectiveness research (CER) fundamentally patient-centered, challenge researchers to adopt or develop methods that improve the timeliness, relevance, and practical application of clinical studies. In this paper, we describe 10 priority areas that address 3 critical needs for research on patient-centered outcomes (PCOR): (1) developing and testing trustworthy methods to identify and prioritize important questions for research; (2) improving the design, conduct, and analysis of clinical research studies; and (3) linking the process and outcomes of actual practice to priorities for research on patient-centered outcomes. We argue that the National Institutes of Health, through its clinical and translational research program, should accelerate the development and refinement of methods for CER by linking a program of methods research to the broader portfolio of large, prospective clinical and health system studies it supports. Insights generated by this work should be of enormous value to PCORI and to the broad range of organizations that will be funding and implementing CER.

    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.

  18. Exploring the Effects of Communication Framed by Environmental Concern in Informal Science Education Contexts

    Informal science education (ISE) venues such as zoos, nature centers, parks, and natural history museums play a critical role in allowing the general public to learn scientific concepts (National Research Council, 2009; 2010). Most adult learning of scientific concepts takes place outside of classrooms and away from work (Rennie and Williams, 2006). It is also true that zoos and natural history museums have stated missions regarding conveying concepts related to the conservation of our natural resources (Krishtalka and Humphrey, 2000; Patrick, Mathews, Ayers, and Tunicliffe, 2007). Theoretically, the successful communication of the desired message of these ISE institutions would inspire a more informed citizenry on the use and conservation of our natural resources. Framing communication is to present a topic in a manner that promote a specific view of the information. Effectively framing information can be an avenue to achieving the goal of ISE institutions (Chong & Druckman, 2007; Nisbet, 2009). Shultz and Zelezny (2003) posit that messages framed by egoistic concerns, concerns which focus on the individual, will be better received by the general public, leading to a greater likelihood for them to become engaged. This dissertation reports on a series of descriptive mixed methods studies conducted at a zoo, a natural history museum, and a science center, exploring the framing effects of communications framed by environmental concern (Schultz, 2001). In two of the studies the researcher examined the relationship between individuals' perceptions of the overlap between their lives and nature, their levels of environmental concern, and their preferences for statements designed to align with the types of environmental concern (i.e. egoistic, social-altruistic, and biospheric). Two studies were conducted using a quasi-experimental design in which the researcher randomly assigned messages framed by environmental concern while also taking measurements of prior involvement

    The effects of group delay distortion on an SMSK satellite communications channel have been investigated. Software and hardware simulations have been used to determine the effects of channel group delay variations with frequency on the bit error rate for a 220 Mbps SMSK channel. These simulations indicate that group delay distortions can significantly degrade the bit error rate performance. The severity of the degradation is dependent on the amount, type, and spectral location of the group delay distortion.
