Parents and caregivers play an important role in sexual socialization of youth, often serving as the primary source of information about sex. For African American rural youth who experience disparate rates of HIV/sexually transmitted infection, improving caregiver-youth communication about sexual topics may help to reduce risky behaviors. This study assessed the impact of an intervention to improve sexual topic communication. A Preintervention-postintervention, quasi-experimental, controlled, and community-based trial. Intervention was in 2 rural North Carolina counties with comparison group in 3 adjacent counties. Participants (n = 249) were parents, caregivers, or parental figures for African American youth aged 10 to 14. Twelve-session curriculum for participating dyads. Audio computer-assisted self-interview to assess changes at 9 months from baseline in communication about general and sensitive sex topics and overall communication about sex. Multivariable models were used to examine the differences between the changes in mean of scores for intervention and comparison groups. Statistically significant differences in changes in mean scores for communication about general sex topics ( P < .0001), communication about sensitive sex topics ( P < .0001), and overall communication about sex ( P < .0001) existed. Differences in change in mean scores remained significant after adjusting baseline scores and other variables in the multivariate models. In Teach One Reach One intervention, adult participants reported improved communication about sex, an important element to support risk reduction among youth in high-prevalence areas.

This paper presents forecasts of likely changes in broadcast satellite technology, the technology of ground terminals, and the technology of terrestrial communications competitive with satellites. The impacts of these changes in technology are then assessed, using a cross-impact model of U.S. domestic telecommunications, to determine the consequences of various possible changes in communications satellite technology. These consequences are discussed in terms of various possible services, for households, businesses, and specialized customers, which might become economically viable as a result of improvements in satellite technology.

Scenarios for Evolving Seismic Crises: Possible Communication Strategies

NASA Astrophysics Data System (ADS)

Steacy, S.

2015-12-01

Recent advances in operational earthquake forecasting mean that we are very close to being able to confidently compute changes in earthquake probability as seismic crises develop. For instance, we now have statistical models such as ETAS and STEP which demonstrate considerable skill in forecasting earthquake rates and recent advances in Coulomb based models are also showing much promise. Communicating changes in earthquake probability is likely be very difficult, however, as the absolute probability of a damaging event is likely to remain quite small despite a significant increase in the relative value. Here, we use a hybrid Coulomb/statistical model to compute probability changes for a series of earthquake scenarios in New Zealand. We discuss the strengths and limitations of the forecasts and suggest a number of possible mechanisms that might be used to communicate results in an actual developing seismic crisis.

Using Roadside Billboard Posters to Increase Admission Rates to Problem Gambling Services: Reflections on Failure.

Calderwood, Kimberly A; Wellington, William J

2015-07-01

Based on the stimulus-response model of advertising, this study sought to increase admission rates to a local problem gambling service (PGS) in Windsor, Ontario, Canada, by adding a series of locally based 10 foot by 20 foot roadside billboard posters to PGS's existing communications tools for a 24-week period. Using proof of performance reports, a pre-post survey of new callers to PGS, a website visit counter, and a media awareness survey, the findings showed that at least some individuals were influenced by billboard exposure, but admission rates continued to decline during the billboard campaign period. While one possible explanation for the communications failure was that the whole PGS communications campaign was below the minimal threshold for communications perception, another possible explanation is that the stimulus-response model of advertising used may not have been appropriate for such advertising that targets behavior change. Reflections on using an information-processing model instead of a stimulus-response model, and considerations of a two-step flow of communication, are provided. Recommendations are made regarding matching communications messages to stages of behavior change, use of online promotion, and strategies for future research. © 2015 Society for Public Health Education.

Chameleons communicate with complex colour changes during contests: different body regions convey different information.

PubMed

Ligon, Russell A; McGraw, Kevin J

2013-01-01

Many animals display static coloration (e.g. of feathers or fur) that can serve as a reliable sexual or social signal, but the communication function of rapidly changing colours (as in chameleons and cephalopods) is poorly understood. We used recently developed photographic and mathematical modelling tools to examine how rapid colour changes of veiled chameleons Chamaeleo calyptratus predict aggressive behaviour during male-male competitions. Males that achieved brighter stripe coloration were more likely to approach their opponent, and those that attained brighter head coloration were more likely to win fights; speed of head colour change was also an important predictor of contest outcome. This correlative study represents the first quantification of rapid colour change using organism-specific visual models and provides evidence that the rate of colour change, in addition to maximum display coloration, can be an important component of communication. Interestingly, the body and head locations of the relevant colour signals map onto the behavioural displays given during specific contest stages, with lateral displays from a distance followed by directed, head-on approaches prior to combat, suggesting that different colour change signals may evolve to communicate different information (motivation and fighting ability, respectively).

A participatory concept of development and communication.

PubMed

Aubel, J

1992-01-01

The predominant position concerning health communication is that it basically consists of spreading carefully designed messages to certain groups to generate individual behavior change. This information transfer involves a 1-way direction and top down strategy. Even though these approaches may change individual knowledge and attitudes, changes in behavior do not always result. Indeed cultural or economic factors often prevent individuals from changing their behavior. Another belief is that health communication strategies should motivate community members and health workers to take part in dialogue and analysis of health problems. Feedback is thus instantaneous. This convergence model incorporates both community members and health workers and encourages them to draw from their own experiences and priorities to delineate strategies at the community and institutional levels. The advantages of the convergence model include: it aims to change community norms rather than individual behavior and to develop mutually acceptable health practices, it improves skills in 2-way communication, and it uses local communicators. This last advantage results in strengthened ability of these communicators to analyze problems and to encourage others among their social networks to participate in problem solving. Thus their participation fosters sustainable changes in health strategies. Several examples of local communicators generating changes in group norms in developing countries exist. Muslim leaders in the Gambia advance child health and family planning. In India and Bangladesh, respected women inform other women about appropriate child nutrition practices. In Malawi, women's groups wrote nutrition songs and choreographed dances to accompany the songs. If people perceive that educational content relates to their personal beliefs and experience, they become motivated. Facilitated structured learning activities such as open-ended stories are the most successful. Health workers should be facilitators and not just senders of the messages.

Critical elements of culturally competent communication in the medical encounter: a review and model.

Teal, Cayla R; Street, Richard L

2009-02-01

Increasing the cultural competence of physicians is one means of responding to demographic changes in the USA, as well as reducing health disparities. However, in spite of the development and implementation of cultural competence training programs, little is known about the ways cultural competence manifests itself in medical encounters. This paper will present a model of culturally competent communication that offers a framework of studying cultural competence 'in action.' First, we describe four critical elements of culturally competent communication in the medical encounter--communication repertoire, situational awareness, adaptability, and knowledge about core cultural issues. We present a model of culturally competent physician communication that integrates existing frameworks for cultural competence in patient care with models of effective patient-centered communication. The culturally competent communication model includes five communication skills that are depicted as elements of a set in which acquisition of more skills corresponds to increasing complexity and culturally competent communication. The culturally competent communication model utilizes each of the four critical elements to fully develop each skill and apply increasingly sophisticated, contextually appropriate communication behaviors to engage with culturally different patients in complex interactions. It is designed to foster maximum physician sensitivity to cultural variation in patients as the foundation of physician-communication competence in interacting with patients.

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

The understanding that global climate change represents a profound threat to the health and well-being of human and nonhuman species worldwide is growing. This article examines the potential of communication and marketing interventions to influence population behavior in ways consistent with climate change prevention and adaptation objectives. Specifically, using a framework based on an ecologic model of public health, the paper examines: (1) the potential of communication and marketing interventions to influence population behaviors of concern, including support for appropriate public policies; (2) potential target audiences for such programs; and (3) the attributes of effective climate change messages. Communication and marketing interventions appear to have considerable potential to promote important population behavior change objectives, but there is an urgent need for additional translational research to effectively harvest this potential to combat climate change.

Do learning collaboratives strengthen communication? A comparison of organizational team communication networks over time.

PubMed

Bunger, Alicia C; Lengnick-Hall, Rebecca

Collaborative learning models were designed to support quality improvements, such as innovation implementation by promoting communication within organizational teams. Yet the effect of collaborative learning approaches on organizational team communication during implementation is untested. The aim of this study was to explore change in communication patterns within teams from children's mental health organizations during a year-long learning collaborative focused on implementing a new treatment. We adopt a social network perspective to examine intraorganizational communication within each team and assess change in (a) the frequency of communication among team members, (b) communication across organizational hierarchies, and (c) the overall structure of team communication networks. A pretest-posttest design compared communication among 135 participants from 21 organizational teams at the start and end of a learning collaborative. At both time points, participants were asked to list the members of their team and rate the frequency of communication with each along a 7-point Likert scale. Several individual, pair-wise, and team level communication network metrics were calculated and compared over time. At the individual level, participants reported communicating with more team members by the end of the learning collaborative. Cross-hierarchical communication did not change. At the team level, these changes manifested differently depending on team size. In large teams, communication frequency increased, and networks grew denser and slightly less centralized. In small teams, communication frequency declined, growing more sparse and centralized. Results suggest that team communication patterns change minimally but evolve differently depending on size. Learning collaboratives may be more helpful for enhancing communication among larger teams; thus, managers might consider selecting and sending larger staff teams to learning collaboratives. This study highlights key future research directions that can disentangle the relationship between learning collaboratives and team networks.

Adequate information and communication systems (ICT) can help to improve the communication in hospitals. Changes to the ICT-infrastructure of hospitals must be planed carefully. In order to support a comprehensive planning, we presented a classification of 81 common errors of the electronic communication on the MIE 2008 congress. Our objective now was to develop a data model that defines specific requirements for an adequate description of electronic communication processes We first applied the method of explicating qualitative content analysis on the error categorization in order to determine the essential process details. After this, we applied the method of subsuming qualitative content analysis on the results of the first step. A data model for the adequate description of electronic communication. This model comprises 61 entities and 91 relationships. The data model comprises and organizes all details that are necessary for the detection of the respective errors. It can be for either used to extend the capabilities of existing modeling methods or as a basis for the development of a new approach.

2018-07-01

Responsive parental communication during an infant's first year has been positively associated with later language outcomes. This study explores responsivity in mother-infant communication by modeling how change in guiding language between 7 and 11 months influences toddler vocabulary development. In a group of 32 mother-child dyads, change in early maternal guiding language positively predicted child language outcomes measured at 18 and 24 months. In contrast, a number of other linguistic variables - including total utterances and non-guiding language - did not correlate with toddler vocabulary development, suggesting a critical role of responsive change in infant-directed communication. We further assessed whether maternal affect during early communication influenced toddler vocabulary outcomes, finding that dominant affect during early mother-infant communications correlated to lower child language outcomes. These findings provide evidence that responsive parenting should not only be assessed longitudinally, but unique contributions of language and affect should also be concurrently considered in future study.

Planning and adapting to a changing climate requires credible information about the magnitude and rate of projected changes. Ouranos, a consortium on regional climatology and adaptation to climate change was launched in the Province of Québec, Canada, ten years ago, with the objective of developing and providing climate information and expertise in support to adaption. Ouranos differs from most other climate service centers by integrating climate modeling activities, impacts and adaptation expertise and climate analysis services under one roof. The Climate Scenarios Group operates at the interface between climate modellers and users and is responsible for developing, producing and communicating climate scenarios to end-users in a consistent manner. This process requires close collaboration with users to define, understand and eventually anticipate their needs. The varied scientific expertise of climate scenarios specialists --who also act as communicators-- has proven to be a key element for successful communication. A large amount of effort is spent on the characterization and communication of the uncertainties involved in scenario construction. Two main activities have been put in place by the experts in climate modeling to address this: (1) a training course on climate models and (2) a fact-sheet summarizing the uncertainty and robustness of the climate change scenario provided for each I&A application. The latter tool ensures the transparency, traceability, and accountability of our products, and at the same time, encourages a sense of shared responsibility for the final choice of climate scenarios. In addition to uncertainty, two other main issues have been identified as essential in communication with users: 1) observed natural variability at relevant scales and 2) reconciliation of the projected trend with the recent observed trend. Our group has devoted substantial resources for the advancement of communication with end-users in these particular areas. This presentation will provide an overview of progress in communicating climate information at the Ouranos Consortium. We will discuss success and failures and future plans, in particular the extent to which Ouranos needs to work with users in decision-making activities.

Anomaly Detection in Dynamic Networks

DOE Office of Scientific and Technical Information (OSTI.GOV)

Turcotte, Melissa

2014-10-14

Anomaly detection in dynamic communication networks has many important security applications. These networks can be extremely large and so detecting any changes in their structure can be computationally challenging; hence, computationally fast, parallelisable methods for monitoring the network are paramount. For this reason the methods presented here use independent node and edge based models to detect locally anomalous substructures within communication networks. As a first stage, the aim is to detect changes in the data streams arising from node or edge communications. Throughout the thesis simple, conjugate Bayesian models for counting processes are used to model these data streams. Amore » second stage of analysis can then be performed on a much reduced subset of the network comprising nodes and edges which have been identified as potentially anomalous in the first stage. The first method assumes communications in a network arise from an inhomogeneous Poisson process with piecewise constant intensity. Anomaly detection is then treated as a changepoint problem on the intensities. The changepoint model is extended to incorporate seasonal behavior inherent in communication networks. This seasonal behavior is also viewed as a changepoint problem acting on a piecewise constant Poisson process. In a static time frame, inference is made on this extended model via a Gibbs sampling strategy. In a sequential time frame, where the data arrive as a stream, a novel, fast Sequential Monte Carlo (SMC) algorithm is introduced to sample from the sequence of posterior distributions of the change points over time. A second method is considered for monitoring communications in a large scale computer network. The usage patterns in these types of networks are very bursty in nature and don’t fit a Poisson process model. For tractable inference, discrete time models are considered, where the data are aggregated into discrete time periods and probability models are fitted to the communication counts. In a sequential analysis, anomalous behavior is then identified from outlying behavior with respect to the fitted predictive probability models. Seasonality is again incorporated into the model and is treated as a changepoint model on the transition probabilities of a discrete time Markov process. Second stage analytics are then developed which combine anomalous edges to identify anomalous substructures in the network.« less

Communication models in environmental health.

PubMed

Guidotti, Tee L

2013-01-01

Communication models common in environmental health are not well represented in the literature on health communication. Risk communication is a systematic approach to conveying essential information about a specific environmental issue and a framework for thinking about community risk and the alternatives for dealing with it. Crisis communication is intended to provide essential information to people facing an emergency in order to mitigate its effects and to enable them to make appropriate decisions, and it is primarily used in emergency management. Corporate communication is intended to achieve a change in attitude or perception of an organization, and its role in environmental health is usually public relations or to rehabilitate a damaged reputation. Environmental health education is a more didactic approach to science education with respect to health and the environment. Social marketing uses conventional marketing methods to achieve a socially desirable purpose but is more heavily used in health promotion generally. Communication models and styles in environmental health are specialized to serve the needs of the field in communicating with the community. They are highly structured and executed in different ways but have in common a relative lack of emphasis on changing personal or lifestyle behavior compared with health promotion and public health in general and a tendency to emphasize content on specific environmental issues and decision frameworks for protecting oneself or the community through collective action.

A Communication Theoretical Modeling of Axonal Propagation in Hippocampal Pyramidal Neurons.

PubMed

Ramezani, Hamideh; Akan, Ozgur B

2017-06-01

Understanding the fundamentals of communication among neurons, known as neuro-spike communication, leads to reach bio-inspired nanoscale communication paradigms. In this paper, we focus on a part of neuro-spike communication, known as axonal transmission, and propose a realistic model for it. The shape of the spike during axonal transmission varies according to previously applied stimulations to the neuron, and these variations affect the amount of information communicated between neurons. Hence, to reach an accurate model for neuro-spike communication, the memory of axon and its effect on the axonal transmission should be considered, which are not studied in the existing literature. In this paper, we extract the important factors on the memory of axon and define memory states based on these factors. We also describe the transition among these states and the properties of axonal transmission in each of them. Finally, we demonstrate that the proposed model can follow changes in the axonal functionality properly by simulating the proposed model and reporting the root mean square error between simulation results and experimental data.

Determination of the key parameters affecting historic communications satellite trends

Namkoong, D.

1984-01-01

Data representing 13 series of commercial communications satellites procured between 1968 and 1982 were analyzed to determine the factors that have contributed to the general reduction over time of the per circuit cost of communications satellites. The model by which the data were analyzed was derived from a general telecommunications application and modified to be more directly applicable for communications satellites. In this model satellite mass, bandwidth-years, and technological change were the variable parameters. A linear, least squares, multiple regression routine was used to obtain the measure of significance of the model. Correlation was measured by coefficient of determination (R super 2) and t-statistic. The results showed that no correlation could be established with satellite mass. Bandwidth-year however, did show a significant correlation. Technological change in the bandwidth-year case was a significant factor in the model. This analysis and the conclusions derived are based on mature technologies, i.e., satellite designs that are evolutions of earlier designs rather than the first of a new generation. The findings, therefore, are appropriate to future satellites only if they are a continuation of design evolution.

This study aims to address difficulties reported by the nursing team during the process of changing the management model in a public hospital in Brazil. This qualitative study used thematic content analysis as proposed by Bardin, and data were analyzed using the theoretical framework of Bolman and Deal. The vertical implementation of Participatory Management contradicted its underlying philosophy and thereby negatively influenced employee acceptance of the change. The decentralized structure of the Participatory Management Model was implemented but shared decision-making was only partially utilized. Despite facilitation of the communication process within the unit, more significant difficulties arose from lack of communication inter-unit. Values and principals need to be shared by teams, however, that will happens only if managers restructure accountabilities changing job descriptions of all team members. Innovative management models that depart from the premise of decentralized decision-making and increased communication encourage accountability, increased motivation and satisfaction, and contribute to improving the quality of care. The contribution of the study is that it describes the complexity of implementing an innovative management model, examines dissent and intentionally acknowledges the difficulties faced by employees in the organization.

Assessing what to address in science communication.

2013-08-20

As members of a democratic society, individuals face complex decisions about whether to support climate change mitigation, vaccinations, genetically modified food, nanotechnology, geoengineering, and so on. To inform people's decisions and public debate, scientific experts at government agencies, nongovernmental organizations, and other organizations aim to provide understandable and scientifically accurate communication materials. Such communications aim to improve people's understanding of the decision-relevant issues, and if needed, promote behavior change. Unfortunately, existing communications sometimes fail when scientific experts lack information about what people need to know to make more informed decisions or what wording people use to describe relevant concepts. We provide an introduction for scientific experts about how to use mental models research with intended audience members to inform their communication efforts. Specifically, we describe how to conduct interviews to characterize people's decision-relevant beliefs or mental models of the topic under consideration, identify gaps and misconceptions in their knowledge, and reveal their preferred wording. We also describe methods for designing follow-up surveys with larger samples to examine the prevalence of beliefs as well as the relationships of beliefs with behaviors. Finally, we discuss how findings from these interviews and surveys can be used to design communications that effectively address gaps and misconceptions in people's mental models in wording that they understand. We present applications to different scientific domains, showing that this approach leads to communications that improve recipients' understanding and ability to make informed decisions.

Active inference, communication and hermeneutics☆

PubMed Central

Friston, Karl J.; Frith, Christopher D.

2015-01-01

Hermeneutics refers to interpretation and translation of text (typically ancient scriptures) but also applies to verbal and non-verbal communication. In a psychological setting it nicely frames the problem of inferring the intended content of a communication. In this paper, we offer a solution to the problem of neural hermeneutics based upon active inference. In active inference, action fulfils predictions about how we will behave (e.g., predicting we will speak). Crucially, these predictions can be used to predict both self and others – during speaking and listening respectively. Active inference mandates the suppression of prediction errors by updating an internal model that generates predictions – both at fast timescales (through perceptual inference) and slower timescales (through perceptual learning). If two agents adopt the same model, then – in principle – they can predict each other and minimise their mutual prediction errors. Heuristically, this ensures they are singing from the same hymn sheet. This paper builds upon recent work on active inference and communication to illustrate perceptual learning using simulated birdsongs. Our focus here is the neural hermeneutics implicit in learning, where communication facilitates long-term changes in generative models that are trying to predict each other. In other words, communication induces perceptual learning and enables others to (literally) change our minds and vice versa. PMID:25957007

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

How do people develop and maintain their beliefs about science? Decades of social science research exist to help us answer this question. The Integrated Model of Communication Influence on Beliefs presented here combines multiple theories that have considered aspects of this process into a comprehensive model to explain how individuals arrive at their scientific beliefs. In this article, we (i) summarize what is known about how science is presented in various news and entertainment media forms; (ii) describe how individuals differ in their choices to be exposed to various forms and sources of communication; (iii) discuss the implications of how individuals mentally process information on the effects of communication; (iv) consider how communication effects can be altered depending on background characteristics and motivations of individuals; and (v) emphasize that the process of belief formation is not unidirectional but rather, feeds back on itself over time. We conclude by applying the Integrated Model of Communication Influence on Beliefs to the complex issue of beliefs about climate change. PMID:23940328

Circle of care modelling: an approach to assist in reasoning about healthcare change using a patient-centric system.

Price, Morgan

2016-10-04

Many health system and health Information and Communication Technology (ICT) projects do not achieve their expected benefits. This paper presents an approach to exploring changes in the healthcare system to better understand the expected improvements and other changes by using a patient-centric modelling approach. Circle of care modeling (CCM) was designed to assist stakeholders in considering healthcare system changes using a patient centric approach. The CCM approach is described. It includes four steps, based on soft systems methodology: finding out, conceptual modelling, structured discussion, and describing potential improvements. There are four visualizations that are used though this process: patient-persona based rich pictures of care flows (as part of finding out), and three models: provider view, communication view, and information repository view (as part of conceptual modelling). Three case studies are presented where CCM was applied to different real-world healthcare problems: 1. Seeking improvements in continuity of care for end of life patients. 2. Exploring current practices for medication communication for ambulatory patients prior to an update of a jurisdictional drug information system. 3. Deciding how to improve attachment of patients to primary care. The cases illustrate how CCM helped stakeholders reason from a patient centered approach about gaps and improvements in care such as: data fragmentation (in 1), coordination efforts of medication management (in 2), and deciding to support a community health centre for unattached patients (in 3). The circle of care modelling approach has proved to be a useful tool in assisting stakeholders explore health system change in a patient centric approach. It is one way to instantiate the important principle of being patient centered into practice when considering health system changes.

Clinical communication is a core component of undergraduate medical training. A consensus statement on the essential elements of the communication curriculum was co-produced in 2008 by the communication leads of UK medical schools. This paper discusses the relational, contextual and technological changes which have affected clinical communication since then and presents an updated curriculum for communication in undergraduate medicine. The consensus was developed through an iterative consultation process with the communication leads who represent their medical schools on the UK Council of Clinical Communication in Undergraduate Medical Education. The updated curriculum defines the underpinning values, core components and skills required within the context of contemporary medical care. It incorporates the evolving relational issues associated with the more prominent role of the patient in the consultation, reflected through legal precedent and changing societal expectations. The impact on clinical communication of the increased focus on patient safety, the professional duty of candour and digital medicine are discussed. Changes in the way medicine is practised should lead rapidly to adjustments to the content of curricula. The updated curriculum provides a model of best practice to help medical schools develop their teaching and argue for resources. Copyright © 2018 Elsevier B.V. All rights reserved.

Interprofessional communication supporting clinical handover in emergency departments: An observation study.

Poor interprofessional communication poses a risk to patient safety at change-of-shift in emergency departments (EDs). The purpose of this study was to identify and describe patterns and processes of interprofessional communication impacting quality of ED change-of-shift handovers. Observation of 66 change-of-shift handovers at two acute hospital EDs in Victoria, Australia. Focus groups with 34 nurse participants complemented the observations. Qualitative data analysis involved content and thematic methods. Four structural components of ED handover processes emerged represented by (ABCD): (1) Antecedents; (2) Behaviours and interactions; (3) Content; and (4) Delegation of ongoing care. Infrequent and ad hoc interprofessional communication and discipline-specific handover content and processes emerged as specific risks to patient safety at change-of-shift handovers. Three themes related to risky and effective practices to support interprofessional communications across the four stages of ED handovers emerged: 1) standard processes and practices, 2) teamwork and interactions and 3) communication activities and practices. Unreliable interprofessional communication can impact the quality of change-of-shift handovers in EDs and poses risk to patient safety. Structured reflective analysis of existing practices can identify opportunities for standardisation, enhanced team practices and effective communication across four stages of the handover process to support clinicians to enhance local handover practices. Future research should test and refine models to support analysis of practice, and identify and test strategies to enhance ED interprofessional communication to support clinical handovers.

Communication impacting financial markets

Since the attribution of the Nobel prize in 2002 to Kahneman for prospect theory, behavioral finance has become an increasingly important subfield of finance. However the main parts of behavioral finance, prospect theory included, understand financial markets through individual investment behavior. Behavioral finance thereby ignores any interaction between participants. We introduce a socio-financial model (Vitting Andersen J. and Nowak A., An Introduction to Socio-Finance (Springer, Berlin) 2013) that studies the impact of communication on the pricing in financial markets. Considering the simplest possible case where each market participant has either a positive (bullish) or negative (bearish) sentiment with respect to the market, we model the evolution of the sentiment in the population due to communication in subgroups of different sizes. Nonlinear feedback effects between the market performance and changes in sentiments are taken into account by assuming that the market performance is dependent on changes in sentiments (e.g., a large sudden positive change in bullishness would lead to more buying). The market performance in turn has an impact on the sentiment through the transition probabilities to change an opinion in a group of a given size. The idea is that if for example the market has observed a recent downturn, it will be easier for even a bearish minority to convince a bullish majority to change opinion compared to the case where the meeting takes place in a bullish upturn of the market. Within the framework of our proposed model, financial markets stylized facts such as volatility clustering and extreme events may be perceived as arising due to abrupt sentiment changes via ongoing communication of the market participants. The model introduces a new volatility measure which is apt of capturing volatility clustering and from maximum-likelihood analysis we are able to apply the model to real data and give additional long term insight into where a market is heading.

The impact of mass communication campaigns in the health field.

PubMed

Alcalay, R

1983-01-01

This article analyzes a series of health education projects that used the mass media to change behavior. First, the article describes how persuasion theories are used to maximize impact in mass communication campaigns. Second, this paper discusses theories of social psychology used in such campaigns. One such theory, cognitive dissonance, explains changes at the level of attitudes, beliefs and opinion. Another theory, social learning, defines strategies of behavior changes. A third theory, concerning diffusion of innovations, helps understand the network of interpersonal relationships essential for the adoption of any innovation. McGuire's inoculation theory suggests strategies to aid resistance to harmful environmental influences (e.g. smoking, excessive drinking, etc.). Third, this work reviews public health campaigns that have used one or more of these theories of social psychology. The first project, dealing with smoking behavior cessation and prevention, mainly used strategies of interpersonal communication for inoculating and modeling useful behavior in order to resist social pressures favorable to smoking. The second project, designed to prevent alcoholism, used the mass media primarily. The objective of this campaign was to obtain changes in knowledge, attitude and behavior in the public through modeling desirable behaviors over public service announcements. The third campaign, a heart disease prevention program, used a combination of mass media and interpersonal communication to achieve changes in lifestyle of the population. Finally, this article describes limitations in using mass media in behavior change health programs.

Diffusion of knowledge and globalization in the web of twentieth century science

Scientific communication is an essential part of modern science: whereas Archimedes worked alone, Newton (correspondence with Hooke, 1676) acknowledged that “If I have seen a little further, it is by standing on the shoulders of Giants.” How is scientific communication reflected in the patterns of citations in scientific papers? How have these patterns changed in the 20th century, as both means of communication and individual transportation changed rapidly, compared to the earlier post-Newton 18th and 19th centuries? Here we discuss a diffusive model for scientific communications, based on a unique 2009 scientometric study of 25 million papers and 600 million citations that encapsulates the epistemology of modern science. The diffusive model predicts and explains, using no adjustable parameters, a surprisingly universal internal structure in the development of scientific research, which is essentially constant across the natural sciences, but which because of globalization changed qualitatively around 1960. Globalization corresponds physically to anomalous diffusion, which has been observed near the molecular glass transition, and can enhance molecular diffusion by factors as large as 100.

A model for educational feedback based on clinical communication skills strategies: beyond the "feedback sandwich".

PubMed

Milan, Felise B; Parish, Sharon J; Reichgott, Michael J

2006-01-01

Feedback is an essential tool in medical education, and the process is often difficult for both faculty and learner. There are strong analogies between the provision of educational feedback and doctor-patient communication during the clinical encounter. Relationship-building skills used in the clinical setting-Partnership, Empathy, Apology, Respect, Legitimation, Support (PEARLS)-can establish trust with the learner to better manage difficult feedback situations involving personal issues, unprofessional behavior, or a defensive learner. Using the stage of readiness to change (transtheoretical) model, the educator can "diagnose" the learner's stage of readiness and employ focused interventions to encourage desired changes. This approach has been positively received by medical educators in faculty development workshops. A model for provision of educational feedback based on communication skills used in the clinical encounter can be useful in the medical education setting. More robust evaluation of the construct validity is required in actual training program situations.

At the intersection of micro and macro: opportunities and challenges for physician-patient communication research.

PubMed

Cline, Rebecca J Welch

2003-05-01

The health care relationship model is undergoing dramatic change. Micro-level communication patterns yield health care relationship models (e.g. paternalism, mutual participation, consumerism). At the same time, macro-level systems appear increasingly likely to influence the nature of micro-level interaction. The intersections of health care communication micro-level and macro-level phenomena provide important venues for research and interventions. This essay identifies theoretical premises regarding the relationships between communication and health-related behavior; explores three prominent and growing macro-level phenomena that observers argue likely influence the physical-patient relationship and communication therein: complementary and alternative medicine, the Internet, and direct-to-consumer advertising of prescription drugs; and offers a research agenda for exploring macro-level influences on micro-level physician-patient communication.

Identity as a Moderator and Mediator of Communication Effects: Evidence and Implications for Message Design.

PubMed

Comello, Maria Leonora G; Farman, Lisa

2016-10-02

Advertisements, movies, and other forms of media content have potential to change behaviors and antecedent psychological states by appealing to identity. However, the mechanisms that are responsible for persuasive effects of such content have not been adequately specified. A recently proposed model of communication effects (the prism model) advances the study of mechanisms and argues that identity can serve as both a moderator and mediator of communication effects on behavior-relevant outcomes. These intervening roles are made possible by the complex nature of identity (including multiple self-concepts and sensitivity to cues) and messages that cue the importance of and activate particular self-concepts. This article builds on development of the model by presenting empirical support based on re-analysis of an experiment in which participants viewed either a more-stigmatizing or less-stigmatizing portrayal of a recovering drug addict. In line with the model's propositions, exposure to the less-stigmatizing condition led to increases in perspective taking which then led to more acceptance (mediation by identity), while level of perspective taking also changed the effect of condition on acceptance (moderation by identity). These results provide support for the model's proposition of simultaneous intervening roles. The authors discuss implications for strategic communication research and practice.

Background South Africa is facing a complex burden of disease arising from a combination of chronic infectious illness and non-communicable diseases. As the burden of chronic diseases (communicable and non-communicable) increases, providing affordable and effective care to the increasing numbers of chronic patients will be an immense challenge. Methods The framework recommended by the Medical Research Council of the United Kingdom for the development and evaluation of complex health interventions was used to conceptualise the intervention. The breakthrough series was utilised for the implementation process. These two frameworks were embedded within the clinical practice improvement model that served as the overarching framework for the development and implementation of the model. Results The Chronic Care Model was ideally suited to improve the facility component and patient experience; however, the deficiencies in other aspects of the health system building blocks necessitated a hybrid model. An integrated chronic disease management model using a health systems approach was initiated across 42 primary health care facilities. The interventions were implemented in a phased approach using learning sessions and action periods to introduce the planned and targeted changes. Conclusion The implementation of the integrated chronic disease management model is feasible at primary care in South Africa provided that systemic challenges and change management are addressed during the implementation process.

The strategic use of noise in pragmatic reasoning.

Bergen, Leon; Goodman, Noah D

2015-04-01

We combine two recent probabilistic approaches to natural language understanding, exploring the formal pragmatics of communication on a noisy channel. We first extend a model of rational communication between a speaker and listener, to allow for the possibility that messages are corrupted by noise. In this model, common knowledge of a noisy channel leads to the use and correct understanding of sentence fragments. A further extension of the model, which allows the speaker to intentionally reduce the noise rate on a word, is used to model prosodic emphasis. We show that the model derives several well-known changes in meaning associated with prosodic emphasis. Our results show that nominal amounts of actual noise can be leveraged for communicative purposes. Copyright © 2015 Cognitive Science Society, Inc.

Morphological and Behavioral Changes in the Pathogenesis of a Novel Mouse Model of Communicating Hydrocephalus

McMullen, Allison B.; Baidwan, Gurlal S.; McCarthy, Ken D.

2012-01-01

The Ro1 model of hydrocephalus represents an excellent model for studying the pathogenesis of hydrocephalus due to its complete penetrance and inducibility, enabling the investigation of the earliest cellular and histological changes in hydrocephalus prior to overt pathology. Hematoxylin and eosin staining, immunofluorescence and electron microscopy were used to characterize the histopathological events of hydrocephalus in this model. Additionally, a broad battery of behavioral tests was used to investigate behavioral changes in the Ro1 model of hydrocephalus. The earliest histological changes observed in this model were ventriculomegaly and disorganization of the ependymal lining of the aqueduct of Sylvius, which occurred concomitantly. Ventriculomegaly led to thinning of the ependyma, which was associated with periventricular edema and areas of the ventricular wall void of cilia and microvilli. Ependymal denudation was subsequent to severe ventriculomegaly, suggesting that it is an effect, rather than a cause, of hydrocephalus in the Ro1 model. Additionally, there was no closure of the aqueduct of Sylvius or any blockages within the ventricular system, even with severe ventriculomegaly, suggesting that the Ro1 model represents a model of communicating hydrocephalus. Interestingly, even with severe ventriculomegaly, there were no behavioral changes, suggesting that the brain is able to compensate for the structural changes that occur in the pathogenesis of hydrocephalus if the disorder progresses at a sufficiently slow rate.

Duke, Pamela; Frankel, Richard M; Reis, Shmuel

2013-01-01

Implementation of the electronic health record (EHR) has changed the dynamics of doctor-patient communication. Physicians train to use EHRs from a technical standpoint, giving only minimal attention to integrating the human dimensions of the doctor-patient relationship into the computer-accompanied medical visit. This article reviews the literature and proposes a model to help clinicians, residents, and students improve physician-patient communication while using the EHR. We conducted a literature search on use of communication skills when interfacing with the EHR. We observed an instructional gap and developed a model using evidence-based communication skills. This model integrates patient-centered interview skills and aims to empower physicians to remain patient centered while effectively using EHRs. It may also serve as a template for future educational and practice interventions for use of the EHR in the examination room.

Improving communication with palliative care cancer patients at home - A pilot study of SAGE & THYME communication skills model.

To pilot an evidence-based communication skills model (SAGE & THYME) with UK District Nurses (DNs) who visit patients with advanced cancer early in the dying trajectory. Evidence suggests that DNs lack confidence in communication skills and in assessing cancer patients' psycho-social needs; also that they lack time. SAGE & THYME is a highly structured model for teaching patient centred interactions. It addresses concerns about confidence and time. Mixed methods. 33 DNs were trained in SAGE & THYME in a three hour workshop and interviewed in focus groups on three occasions: pre-training, immediately post-training and two months post-training. Questionnaires measuring perceived outcomes of communication, confidence in communication and motivation to use SAGE & THYME were administered at the focus groups. SAGE & THYME provided a structure for conversations and facilitated opening and closing of interactions. The main principle of patient centeredness was reportedly used by all. Knowledge about communication behaviours helpful to patients improved and was sustained two months after training. Increased confidence in communication skills was also sustained. Motivation to use SAGE & THYME was high and remained so at two months, and some said the model saved them time. Challenges with using the model included controlling the home environment and a change in style of communication which was so marked some DNs preferred to use it with new patients. Training DNs in SAGE & THYME in a three hour workshop appears to be a promising model for improving communication skills when working with cancer patients. Crown Copyright © 2015.

Region-Specific Changes in Gamma and Beta2 Rhythms in NMDA Receptor Dysfunction Models of Schizophrenia

PubMed Central

Roopun, Anita K.; Cunningham, Mark O.; Racca, Claudia; Alter, Kai; Traub, Roger D.; Whittington, Miles A.

2008-01-01

Cognitive disruption in schizophrenia is associated with altered patterns of spatiotemporal interaction associated with multiple electroencephalogram (EEG) frequency bands in cortex. In particular, changes in the generation of gamma (30–80 Hz) and beta2 (20–29 Hz) rhythms correlate with observed deficits in communication between different cortical areas. Aspects of these changes can be reproduced in animal models, most notably those involving acute or chronic reduction in glutamatergic synaptic communication mediated by N-methyl D-aspartate (NMDA) receptors. In vitro electrophysiological and immunocytochemical approaches afforded by such animal models continue to reveal a great deal about the mechanisms underlying EEG rhythm generation and are beginning to uncover which basic molecular, cellular, and network phenomena may underlie their disruption in schizophrenia. Here we briefly review the evidence for changes in γ-aminobutyric acidergic (GABAergic) and glutamatergic function and address the problem of region specificity of changes with quantitative comparisons of effects of ketamine on gamma and beta2 rhythms in vitro. We conclude, from available evidence, that many observed changes in markers for GABAergic function in schizophrenia may be secondary to deficits in NMDA receptor–mediated excitatory synaptic activity. Furthermore, the broad range of changes in cortical dynamics seen in schizophrenia—with contrasting effects seen in different brain regions and for different frequency bands—may be more directly attributable to underlying deficits in glutamatergic neuronal communication rather than GABAergic inhibition alone.

Effectively communicate results from a community exposure study to meet predetermined community priorities, maintaining ethical principles of autonomy, empowerment and justice. The community established principles for the communications and a plan to inform study participants, community and other stakeholders of results and recommendations in a novel sequence: the "Community-First" communication model. The communications resulted in positive actions including company sponsored free bottled water, accepted by 77.6% of eligible households. Over 95% of participants in a follow-up survey had made some change to residential water supplies. Serum perfluorooctanoate levels were reduced. Government agencies acted on the results. The unique communication approach generated workable solutions to the problem investigated, raised community awareness and modified behaviors. Information generated a "free market" of community-level solutions. Each major stakeholder voluntarily adopted a "precautionary principle."

The CLER model is presented to nursing professionals as a model for planning and implementing change in interpersonal, institutional and cultural settings. It is useful for generating other models by modeling reality as actually encountered by change agents and adopters. The CLER model is related philosophically to systems thinking (that there is interdependence among social entities), dialectical thinking (that there is mutual shaping among social processes) and constructivist thinking (that human beings take part in creating their own reality).

Communication theory and the search for effective feedback.

PubMed

Simonds, S K

1995-01-01

If messages transmitted to the public, patients and health professionals could be assured of being received, understood and acted on as intended by the senders of messages, there would be little need to focus on communications and feedback. That the physician's office, the healthcare system and the community are littered with messages that 'never got through' attests to the problem of ineffective communications and the absence of effective feedback. Communication theorists, health psychologists and thoughtful health professionals, particularly those working in community hypertension programmes, have developed approaches that improve the probabilities of 'getting the message through'. Theory-based communications with built-in feedback and 'feed-forward' enhance the probabilities of success considerably. This presentation explores these problems using the SMCR model of communication. Differences between linear models and transactional models are discussed. On the assumption that the health message environments of the future will be increasingly complex with highly differentiated target audiences in a rapid paced computer and electronically driven world, 'getting the message through' will become an even greater challenge than in the recent past. Specific steps to change communication approaches in this setting are proposed.

Theory and practice in health communication campaigns: a critical interrogation.

PubMed

Dutta-Bergman, Mohan J

2005-01-01

In recent reviews of the body of work on health campaigns, communication scholars discussed the importance of reflective thinking about the capacity of campaigns to effect change; this reflective thinking is especially important in the realm of the increasing gaps in society between the health rich and the health poor and the increasing marginalization of the poorer sections of society. This article critically reviews 3 central theories of health communication campaigns that represent the dominant cognitive approach: theory of reasoned action, health belief model, and the extended parallel process model. After articulating the limitations of these theoretical approaches, the article summarizes new directions in theory, methodology, and application of health communication campaigns targeting marginalized populations.

2009-03-01

To provide a brief overview of 15 selected persuasion theories and models, and to present examples of their use in health communication research. The theories are categorized as message effects models, attitude-behavior approaches, cognitive processing theories and models, consistency theories, inoculation theory, and functional approaches. As it is often the intent of a practitioner to shape, reinforce, or change a patient's behavior, familiarity with theories of persuasion may lead to the development of novel communication approaches with existing patients. This article serves as an introductory primer to theories of persuasion with applications to health communication research. Understanding key constructs and general formulations of persuasive theories may allow practitioners to employ useful theoretical frameworks when interacting with patients.

A Communication Intervention to Reduce Resistiveness in Dementia Care: A Cluster Randomized Controlled Trial.

2017-08-01

Nursing home (NH) residents with dementia exhibit challenging behaviors or resistiveness to care (RTC) that increase staff time, stress, and NH costs. RTC is linked to elderspeak communication. Communication training (Changing Talk [CHAT]) was provided to staff to reduce their use of elderspeak. We hypothesized that CHAT would improve staff communication and subsequently reduce RTC. Thirteen NHs were randomized to intervention and control groups. Dyads (n = 42) including 29 staff and 27 persons with dementia were videorecorded during care before and/or after the intervention and at a 3-month follow-up. Videos were behaviorally coded for (a) staff communication (normal, elderspeak, or silence) and (b) resident behaviors (cooperative or RTC). Linear mixed modeling was used to evaluate training effects. On average, elderspeak declined from 34.6% (SD = 18.7) at baseline by 13.6% points (SD = 20.00) post intervention and 12.2% points (SD = 22.0) at 3-month follow-up. RTC declined from 35.7% (SD = 23.2) by 15.3% points (SD = 32.4) post intervention and 13.4% points (SD = 33.7) at 3 months. Linear mixed modeling determined that change in elderspeak was predicted by the intervention (b = -12.20, p = .028) and baseline elderspeak (b = -0.65, p < .001), whereas RTC change was predicted by elderspeak change (b = 0.43, p < .001); baseline RTC (b = -0.58, p < .001); and covariates. A brief intervention can improve communication and reduce RTC, providing an effective nonpharmacological intervention to manage behavior and improve the quality of dementia care.

Information infrastructure for emergency medical services.

2005-01-01

The pre-hospital emergency medical and public safety information environment is nearing a threshold of significant change. The change is driven in part by several emerging technologies such as secure, high-speed wireless communication in the local and wide area networks (wLAN, 3G), Geographic Information Systems (GIS), Global Positioning Systems (GPS), and powerful handheld computing and communication services, that are of sufficient utility to be more widely adopted. We propose a conceptual model to enable improved clinical decision making in the pre-hospital environment using these change agents.

Objectives Effectively communicate results from a community exposure study to meet predetermined community priorities, maintaining ethical principles of autonomy, empowerment and justice. Methods The community established principles for the communications and a plan to inform study participants, community and other stakeholders of results and recommendations in a novel sequence: the “Community-First” communication model. Results The communications resulted in positive actions including company sponsored free bottled water, accepted by 77.6% of eligible households. Over 95% of participants in a follow-up survey had made some change to residential water supplies. Serum PFOA levels were reduced. Government agencies acted on the results. Conclusions The unique communication approach generated workable solutions to the problem investigated, raised community awareness and modified behaviors. Information generated a “free market” of community-level solutions. Each major stakeholder voluntarily adopted a “precautionary principle”. PMID:19209035

An optofluidic channel model for in vivo nanosensor networks in human blood

2017-05-01

In vivo Wireless Nanosensor Networks (iWNSNs) consist of nano-sized communicating devices with unprece- dented sensing and actuation capabilities, which are able to operate inside the human body. iWNSNs are a disruptive technology that enables the monitoring and control of biological processes at the cellular and sub- cellular levels. Compared to ex vivo measurements, which are conducted on samples extracted from the human body, iWNSNs can track (sub) cellular processes when and where they occur. Major progress in the field of na- noelectronics, nanophotonics and wireless communication is enabling the interconnection of nanosensors. Among others, plasmonic nanolasers with sub-micrometric footprint, plasmonic nano-antennas able to confine light in nanometric structures, and single-photon detectors with unrivaled sensitivity, enable the communication among implanted nanosensors in the near infrared and optical transmission windows. Motivated by these results, in this paper, an optofluidic channel model is developed to investigate the communication properties and temporal dynamics between a pair of in vivo nanosensors in the human blood. The developed model builds upon the authors' recent work on light propagation modeling through multi-layered single cells and cell assemblies and takes into account the geometric, electromagnetic and microfluidic properties of red blood cells in the human circulatory system. The proposed model guides the development of practical communication strategies among nanosensors, and paves the way through new nano-biosensing strategies able to identify diseases by detecting the slight changes in the channel impulse response, caused by either the change in shape of the blood cells or the presence of pathogens.

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

PubMed

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.

The impact of communications on the self-regulation of health beliefs, decisions, and behavior.

PubMed

Leventhal, H; Safer, M A; Panagis, D M

1983-01-01

The models used in the study of communication and health behavior have changed from those describing how to impose health actions on relatively passive respondents to models describing how respondents regulate their own health practices. We have traced the change from the fear-drive model, which described how fear induced change, to the parallel response model, which described how subjects processed information and generated coping responses to solve the problem posed by both the objective health threat and by their subjective fear. The data supporting this change showed that increasing fear led to more favorable attitudes but that fear alone was insufficient to create action: Specific action instructions had to be added to both high and low fear and both combinations produced the same level of health action. Neither the data nor the parallel model specified what subjects learned about the threat that made exposure to a high or low fear message necessary for behavior change. The parallel response model has been elaborated into a more complete systems model and new studies show how health threats are represented. They have found attributes such as IDENTITY (label and symptoms), CAUSES, TIME LINES or duration, and CONSEQUENCES, that set goals and criteria to generate and evaluate problem solving (coping) behavior. Suggestions are made for applying this more complete model to public health practice.

Conceptual data modeling of wildlife response indicators to ecosystem change in the Arctic

USGS Publications Warehouse

Walworth, Dennis; Pearce, John M.

2015-08-06

Large research studies are often challenged to effectively expose and document the types of information being collected and the reasons for data collection across what are often a diverse cadre of investigators of differing disciplines. We applied concepts from the field of information or data modeling to the U.S. Geological Survey (USGS) Changing Arctic Ecosystems (CAE) initiative to prototype an application of information modeling. The USGS CAE initiative is collecting information from marine and terrestrial environments in Alaska to identify and understand the links between rapid physical changes in the Arctic and response of wildlife populations to these ecosystem changes. An associated need is to understand how data collection strategies are informing the overall science initiative and facilitating communication of those strategies to a wide audience. We explored the use of conceptual data modeling to provide a method by which to document, describe, and visually communicate both enterprise and study level data; provide a simple means to analyze commonalities and differences in data acquisition strategies between studies; and provide a tool for discussing those strategies among researchers and managers.

Communicating Climate Change: the Problem of Knowing and Doing.

Wildcat, D.

2008-12-01

The challenge of global warming and climate change may illustrate better than any recent phenomenon that quite independent of the science associated with our assessment, modeling, mitigation strategies and adaptation to the multiple complex processes that characterize this phenomenon, our greatest challenge resides in creating systems where knowledge can be usefully communicated to the general public. Knowledge transfer will pose significant challenges when addressing a topic that often leaves the ill-informed and non-scientist overwhelmed with pieces of information and paralyzed with a sense that there is nothing to be done to address this global problem. This communication problem is very acute in North American indigenous communities where a first-hand, on-the-ground, experience of climate change is indisputable, but where the charts, graphs and sophisticated models presented by scientists are treated with suspicion and often not explained very well. This presentation will discuss the efforts of the American Indian and Alaska Native Climate Change Working Group to prepare future generations of AI/AN geoscience professionals, educators, and a geoscience literate AI/AN workforce, while insuring that our Indigenous tribal knowledges of land- and sea-scapes, and climates are valued, used and incorporated into our tribal exercise of geoscience education and research. The Working Group's efforts are already suggesting the communication problem for Indigenous communities will best be solved by 'growing' our own culturally competent Indigenous geoscience professionals.

Multimission Advanced Communications Hybrid Environment for Test and Evaluation (MACHETE) is a suite of software tools that simulates the behaviors of communication networks to be used in space exploration, and predict the performance of established and emerging space communication protocols and services. MACHETE consists of four general software systems: (1) a system for kinematic modeling of planetary and spacecraft motions; (2) a system for characterizing the engineering impact on the bandwidth and reliability of deep-space and in-situ communication links; (3) a system for generating traffic loads and modeling of protocol behaviors and state machines; and (4) a system of user-interface for performance metric visualizations. The kinematic-modeling system makes it possible to characterize space link connectivity effects, including occultations and signal losses arising from dynamic slant-range changes and antenna radiation patterns. The link-engineering system also accounts for antenna radiation patterns and other phenomena, including modulations, data rates, coding, noise, and multipath fading. The protocol system utilizes information from the kinematic-modeling and link-engineering systems to simulate operational scenarios of space missions and evaluate overall network performance. In addition, a Communications Effect Server (CES) interface for MACHETE has been developed to facilitate hybrid simulation of space communication networks with actual flight/ground software/hardware embedded in the overall system.

The work reported here assesses the coverage achieved by two sales-based approaches to distributing a complementary food supplement (KOKO Plus™) to infants and young children in Ghana. Delivery Model 1 was conducted in the Northern Region of Ghana and used a mixture of health extension workers (delivering behavior change communications and demand creation activities at primary healthcare centers and in the community) and petty traders recruited from among beneficiaries of a local microfinance initiative (responsible for the sale of the complementary food supplement at market stalls and house to house). Delivery Model 2 was conducted in the Eastern Region of Ghana and used a market-based approach, with the product being sold through micro-retail routes (i.e., small shops and roadside stalls) in three districts supported by behavior change communications and demand creation activities led by a local social marketing company. Both delivery models were implemented sub-nationally as 1-year pilot programs, with the aim of informing the design of a scaled-up program. A series of cross-sectional coverage surveys was implemented in each program area. Results from these surveys show that Delivery Model 1 was successful in achieving and sustaining high (i.e., 86%) effective coverage (i.e., the child had been given the product at least once in the previous 7 days) during implementation. Effective coverage fell to 62% within 3 months of the behavior change communications and demand creation activities stopping. Delivery Model 2 was successful in raising awareness of the product (i.e., 90% message coverage), but effective coverage was low (i.e., 9.4%). Future programming efforts should use the health extension / microfinance / petty trader approach in rural settings and consider adapting this approach for use in urban and peri-urban settings. Ongoing behavior change communications and demand creation activities is likely to be essential to the continued success of such programming. PMID:27755554

Discrete Model of Opinion Changes Using Knowledge and Emotions as Control Variables

Sobkowicz, Pawel

2012-01-01

We present a new model of opinion changes dependent on the agents emotional state and their information about the issue in question. Our goal is to construct a simple, yet nontrivial and flexible representation of individual attitude dynamics for agent based simulations, that could be used in a variety of social environments. The model is a discrete version of the cusp catastrophe model of opinion dynamics in which information is treated as the normal factor while emotional arousal (agitation level determining agent receptiveness and rationality) is treated as the splitting factor. Both variables determine the resulting agent opinion, which itself can be in favor of the studied position, against it, or neutral. Thanks to the flexibility of implementing communication between the agents, the model is potentially applicable in a wide range of situations. As an example of the model application, we study the dynamics of a set of agents communicating among themselves via messages. In the example, we chose the simplest, fully connected communication topology, to focus on the effects of the individual opinion dynamics, and to look for stable final distributions of agents with different emotions, information and opinions. Even for such simplified system, the model shows complex behavior, including phase transitions due to symmetry breaking by external propaganda. PMID:22984516

Analysis of the performance of a wireless optical multi-input to multi-output communication system.

PubMed

Bushuev, Denis; Arnon, Shlomi

2006-07-01

We investigate robust optical wireless communication in a highly scattering propagation medium using multielement optical detector arrays. The communication setup consists of synchronized multiple transmitters that send information to a receiver array and an atmospheric propagation channel. The mathematical model that best describes this scenario is multi-input to multi-output communication through stochastic slow changing channels. In this model, signals from m transmitters are received by n receiver-detectors. The channel transfer function matrix is G, and its size is n x m. G(i,j) is the transfer function from transmitter i to detector j, and m > or = n. We adopt a quasi-stationary approach in which the channel time variation has a negligible effect on communication performance over a burst. The G matrix is calculated on the basis of the optical transfer function of the atmospheric channel (composed of aerosol and turbulence elements) and the receiver's optics. In this work we derive a performance model using environmental data, such as documented turbulence and aerosol models and noise statistics. We also present the results of simulations conducted for the proposed detection algorithm.

Understanding global climate change scenarios through bioclimate stratification

2017-08-01

Despite progress in impact modelling, communicating and understanding the implications of climatic change projections is challenging due to inherent complexity and a cascade of uncertainty. In this letter, we present an alternative representation of global climate change projections based on shifts in 125 multivariate strata characterized by relatively homogeneous climate. These strata form climate analogues that help in the interpretation of climate change impacts. A Random Forests classifier was calculated and applied to 63 Coupled Model Intercomparison Project Phase 5 climate scenarios at 5 arcmin resolution. Results demonstrate how shifting bioclimate strata can summarize future environmental changes and form a middle ground, conveniently integrating current knowledge of climate change impact with the interpretation advantages of categorical data but with a level of detail that resembles a continuous surface at global and regional scales. Both the agreement in major change and differences between climate change projections are visually combined, facilitating the interpretation of complex uncertainty. By making the data and the classifier available we provide a climate service that helps facilitate communication and provide new insight into the consequences of climate change.

A Quadruped Robot Exhibiting Spontaneous Gait Transitions from Walking to Trotting to Galloping.

PubMed

Owaki, Dai; Ishiguro, Akio

2017-03-21

The manner in which quadrupeds change their locomotive patterns-walking, trotting, and galloping-with changing speed is poorly understood. In this paper, we provide evidence for interlimb coordination during gait transitions using a quadruped robot for which coordination between the legs can be self-organized through a simple "central pattern generator" (CPG) model. We demonstrate spontaneous gait transitions between energy-efficient patterns by changing only the parameter related to speed. Interlimb coordination was achieved with the use of local load sensing only without any preprogrammed patterns. Our model exploits physical communication through the body, suggesting that knowledge of physical communication is required to understand the leg coordination mechanism in legged animals and to establish design principles for legged robots that can reproduce flexible and efficient locomotion.

Enabling Flexible and Continuous Capability Invocation in Mobile Prosumer Environments

2012-01-01

Mobile prosumer environments require the communication with heterogeneous devices during the execution of mobile services. These environments integrate sensors, actuators and smart devices, whose availability continuously changes. The aim of this paper is to design a reference architecture for implementing a model for continuous service execution and access to capabilities, i.e., the functionalities provided by these devices. The defined architecture follows a set of software engineering patterns and includes some communication paradigms to cope with the heterogeneity of sensors, actuators, controllers and other devices in the environment. In addition, we stress the importance of the flexibility in capability invocation by allowing the communication middleware to select the access technology and change the communication paradigm when dealing with smart devices, and by describing and evaluating two algorithms for resource access management.

This meta-analysis examined the validity of various theoretical assumptions about cognitive and behavioral change following a communication recommending condom use. The synthesis comprised 82 treatment and 29 control groups included in 46 longitudinal reports with measures of perceived severity and susceptibility, attitudes and expectancies, norms, perceptions of control, intentions, knowledge, behavioral skills, or condom use. Results indicated that across the sample of studies, communications taught recipients about facts related to HIV and also induced favorable attitudes and expectancies, greater control perceptions, and stronger intentions to use condoms in the future. Moreover, messages that presented attitudinal information and modeled behavioral skills led to increased condom use. Results are discussed in the context of theories of human behavior and change and in reference to HIV-prevention interventions. PMID:12683737

Communication failures during clinical handovers lead to a poor patient outcome: Lessons from a case report.

Manias, Elizabeth; Geddes, Fiona; Watson, Bernadette; Jones, Dorothy; Della, Phillip

2015-01-01

In the emergency department, communication failures occur in clinical handover due to the urgent, changing and unpredictable nature of care provision. We present a case report of a female patient who was assaulted, and identify how various factors interacted to produce communication failures at multiple clinical handovers, leading to a poor patient outcome. Several handovers created many communication failures at diverse time points. The bedside medical handover produced misunderstandings during verbal exchange of information between emergency department consultants and junior doctors, and there was miscommunication involving plastic registrars. There was a failure in adequately informing the general practitioner and the patient relating to follow-up care after discharge. Deficiencies of communication occurred with conveying changes in an investigative report. Communication could be improved by dividing the conduct of handover in a quiet room and at the bedside, ensuring multiple sources of information are used and encouraging role-modelling behaviours for junior clinicians.

Consultant-Client Relationship and Knowledge Transfer in Small- and Medium-Sized Enterprises Change Processes.

Martinez, Luis F; Ferreira, Aristides I; Can, Amina B

2016-04-01

Based on Szulanski's knowledge transfer model, this study examined how the communicational, motivational, and sharing of understanding variables influenced knowledge transfer and change processes in small- and medium-sized enterprises, particularly under projects developed by funded programs. The sample comprised 144 entrepreneurs, mostly male (65.3%) and mostly ages 35 to 45 years (40.3%), who filled an online questionnaire measuring the variables of "sharing of understanding," "motivation," "communication encoding competencies," "source credibility," "knowledge transfer," and "organizational change." Data were collected between 2011 and 2012 and measured the relationship between clients and consultants working in a Portuguese small- and medium-sized enterprise-oriented action learning program. To test the hypotheses, structural equation modeling was conducted to identify the antecedents of sharing of understanding, motivational, and communicational variables, which were positively correlated with the knowledge transfer between consultants and clients. This transfer was also positively correlated with organizational change. Overall, the study provides important considerations for practitioners and academicians and establishes new avenues for future studies concerning the issues of consultant-client relationship and the efficacy of Government-funded programs designed to improve performance of small- and medium-sized enterprises. © The Author(s) 2016.

Indicators have become one of the primary tools for Strategic Environmental Assessment (SEA) in the Chinese context, but what does this use of indicators mean for communication within the SEA processes? This article explores how the selection and use of indicators influence the communication between different stakeholders involved in SEA. The article provides a conceptual communication model covering directions and level of communication. Using this model on empirical findings from interviews with two specific SEA cases and from general experience collected through an online survey, the results suggest that indicators are used mainly in internal communication although a change ofmore » approach, with more external communication and stakeholder engagement, is taking place as a consequence of working with indicators in the SEA. However, the external communication mainly involves the experts and other relevant sectors (planning, energy, land use, forestry, etc.), the involvement of the public and NGOs is still not well implemented in Chinese SEA practice, and the direction of communication is mainly one-way channel of providing information rather than a two-way channel of dialogue and participation. Highlights: • Exploring indicators' influence on the communication in SEA with Chinese experience. • Providing a conceptual model covering directions and level of communication in SEA. • Empirical findings from two specific SEA cases and collected general experience. • The external communication mainly involves the experts and other sectors. • More one-way information provision than two-way dialogue and participation.« less

PubMed

Murray-Johnson, Lisa; Witte, Kim; Boulay, Marc; Figueroa, Maria Elena; Storey, Douglas; Tweedie, Ian

Scholars within the fields of public health, health education, health promotion, and health communication look to specific theories to explain health behavior change. The purpose of this article is to critically compare four health theories and key variables within them with regard to behavior change in the area of reproductive health. Using cross-country analyses of Ghana, Nepal, and Nicaragua (data sets provided by the Center for Communication Programs, Johns Hopkins University), the authors looked at the Health Belief Model, Theory of Reasoned Action, Extended Parallel Process Model, and Social Cognitive Theory for these two defined objectives. Results show that all four theories provide an excellent fit to the data, but that certain variables within them may have particular value for understanding specific aspects of behavior change. Recommendations for the selection of theories to use as guidelines in the design and evaluation of reproductive health programs are provided.

Better Communication Through Collaboration: Lessons Learned from a New Model of Science Communication Education

NASA Astrophysics Data System (ADS)

Hayden, T.

2011-12-01

Direct, effective communication with the public is an increasingly important part of the earth scientist's professional toolkit. Earth sciences issues, including climate change, ocean acidification, energy extraction and use and geological hazard assessment, are increasingly relevant to public debates, yet recent, dramatic changes in the media business have led to decreased coverage of science. Earth scientists must increasingly shoulder the burden of informing the broad public themselves, and in collaboration with professional communicators. Fortunately, the tools and venues needed to do so have never been more accessible. This presentation will describe a new model of science communication education, based on bringing together collaborating teams of students with diverse backgrounds in the sciences, engineering and journalism. The project-based approach uses group workshopping and multiple rounds of peer- and instructor-guided revision to leverage diverse expertise and facilitate both primary knowledge gain and comprehensive, effective and meaningful training and experience in audience-focused outreach, media interaction, and journalism. Courses build from fundamental communications theory to the end goal of publication in professional outlets. Course goals are regularly enhanced and reinforced with internships and individual study projects. Using examples from a series of courses and projects developed at Stanford University over the past three years, I will describe the theory and strategies underlying this new approach to science communication education, what it has to offer for scientists and journalists alike, and key points to consider for effective implementation. I will also show how combining the knowledge, expertise and experience of STEM and journalism students can inform a new model of science journalism, based on exploring and communicating the process of science, not just the results, that can avoid many of the common pitfalls of science journalism. I will present a preliminary assessment of outcomes from three courses at Stanford - environmental communications, environmental journalism and multimedia storytelling for earth scientists - including publications, retrospective post assessment of student abilities and attitudes, and ongoing application of course goals in professional and/or educational settings.

Oxytocin receptor and Mecp2 308/Y knockout mice exhibit altered expression of autism-related social behaviors.

PubMed

Pobbe, Roger L H; Pearson, Brandon L; Blanchard, D Caroline; Blanchard, Robert J

2012-12-05

The development of tasks measuring behaviors specific to the three major symptom categories for autism makes it possible to differentiate mouse models of autism spectrum disorders (ASD) in terms of changes in these specific categories. Prior studies indicate that BTBR T+tf/J mice, the strain that has been evaluated most extensively, show autism-relevant changes in all three symptom categories; reciprocal social interactions; communication; and repetitive, ritualized behaviors. This report reviews the behaviors of oxytocin receptor (Oxtr) and Mecp2(308/Y) wild-type (WT) and knockout (KO) mice, in a number of tests specifically designed to provide information on behaviors that may show functional parallels to the core symptoms of ASD. Oxtr KO mice show robust decreases in reciprocal social interactions, and reduced levels of communication, but no changes in repetitive, ritualized behaviors; whereas Mecp2(308/Y) KO mice show a slight but consistent enhancement of social behavior and communication, and no changes in repetitive, ritualized behaviors. This data base, although small, strongly indicates that mouse models can sort the diagnostic symptoms of autism, and suggests that biological and physiological analyses of these strains may be capable of providing differential information on the brain systems involved in particular symptoms of this disorder. Profiles of behavioral changes in other mouse models of ASD should provide additional specificity in the search for biomarkers associated with particular ASD symptoms and symptom clusters.

Lakkaraju, Kiran; Speed, Ann Elizabeth

Attitudes play a significant role in determining how individuals process information and behave. In this paper we have developed a new computational model of population wide attitude change that captures the social level: how individuals interact and communicate information, and the cognitive level: how attitudes and concept interact with each other. The model captures the cognitive aspect by representing each individuals as a parallel constraint satisfaction network. The dynamics of this model are explored through a simple attitude change experiment where we vary the social network and distribution of attitudes in a population.

Communication for HIV/AIDS prevention in Kenya: social-cultural considerations.

PubMed

Muturi, Nancy

2005-01-01

The acquired immune deficiency syndrome (AIDS) epidemic is spreading fast in Africa in spite of the various efforts and resources put in place to prevent it. In Kenya, reproductive health programs have used the mass media and other communication interventions to inform and educate the public about the disease and to promote behavior change and healthy sexual practices. This effort has led to a discrepancy between awareness and behavioral change among people of reproductive age. In this article I examine the discrepancy in Kenya from a communications perspective addressing social cultural and related factors contributing to the lack of change in behavior and sexual practices. I draw on the theoretical framework of Grunig's model of excellence in communication, the importance of understanding and relationship building between programs and their stakeholders. Data were gathered qualitatively using focus groups and in-depth interviews among men and women in rural Kenya. Key findings indicate that although awareness of sexually transmitted diseases (STDs) including human immunodeficiency virus (HIV)/AIDS is high in Kenya, a majority of the population, particularly those in the rural communities, lack understanding of the communicated messages. They also lack the knowledge of other ways of transmitting HIV particularly among those not sexually involved. Cultural beliefs, values, norms, and myths have played a role in the rapidly increasing epidemic in the rural communities and yet HIV/AIDS communication programs have not addressed these factors adequately. I conclude that successful behavior change communication must include strategies that focus on increasing understanding of the communicated messages and understanding of the audience through application of appropriate methodologies. Building a relationship with the audience or stakeholders through dialogues and two-way symmetrical communication contributes toward this understanding and the maintenance of the newly adopted behaviors and practices.

Developmental changes in parent-child communication throughout adolescence.

This study examined how parent-child communication regarding adolescent unsupervised activities develops over the course of adolescence. We used questionnaire data from 390 adolescents (58% girls; 90% European Canadian) who were followed from age 12 to 19. Latent growth curve modeling revealed curvilinear developmental changes that differed for boys and girls. From age 14 to 19 (but not from age 12 to 14) a linear decrease in parental control was found for both genders. For girls, parent-child communication decreased in early adolescence, as indicated by decreasing parental solicitation, decreasing adolescent disclosure, and increasing secrecy. Girls' communication with parents intensified in middle adolescence, as indicated by increasing parental solicitation, increasing adolescent disclosure, and decreasing adolescent secrecy. For boys, disclosure declined in early adolescence, but secrecy and solicitation were stable throughout adolescence. Parental knowledge decreased from age 12 to 19 for both genders but was temporarily stable for middle adolescent girls. The meaning of these developmental changes, their timing, and gender differences are discussed. PsycINFO Database Record (c) 2013 APA, all rights reserved.

Climate change and European forests: what do we know, what are the uncertainties, and what are the implications for forest management?

The knowledge about potential climate change impacts on forests is continuously expanding and some changes in growth, drought induced mortality and species distribution have been observed. However despite a significant body of research, a knowledge and communication gap exists between scientists and non-scientists as to how climate change impact scenarios can be interpreted and what they imply for European forests. It is still challenging to advise forest decision makers on how best to plan for climate change as many uncertainties and unknowns remain and it is difficult to communicate these to practitioners and other decision makers while retaining emphasis on the importance of planning for adaptation. In this paper, recent developments in climate change observations and projections, observed and projected impacts on European forests and the associated uncertainties are reviewed and synthesised with a view to understanding the implications for forest management. Current impact assessments with simulation models contain several simplifications, which explain the discrepancy between results of many simulation studies and the rapidly increasing body of evidence about already observed changes in forest productivity and species distribution. In simulation models uncertainties tend to cascade onto one another; from estimating what future societies will be like and general circulation models (GCMs) at the global level, down to forest models and forest management at the local level. Individual climate change impact studies should not be uncritically used for decision-making without reflection on possible shortcomings in system understanding, model accuracy and other assumptions made. It is important for decision makers in forest management to realise that they have to take long-lasting management decisions while uncertainty about climate change impacts are still large. We discuss how to communicate about uncertainty - which is imperative for decision making - without diluting the overall message. Considering the range of possible trends and uncertainties in adaptive forest management requires expert knowledge and enhanced efforts for providing science-based decision support.

2002-03-01

This project was designed to catalyze curricular changes to better prepare students for the workplace. Industrial managers provided a list of 16 characteristics valued in the workplace: most were NOT related to science course content. The project formed 5 teams each including 3M professionals and students. Each team developed curricular changes in one of the 16 areas. Team goals were to improve skills in communication, data analysis, business/economics, team problem solving, and culture competency. Curricular changes realized include communication skill activities embodied in science courses and faculty communication teaching skill seminars, self learning tools in data analysis, statistics and model building, a new course developed with assistance from 3M personnel focussing on topics directly related to technological industries, high performance team problem solving training/coaching for faculty and workshops for students and faculty relative to importance of cultural competencies in the workplace, and a new course focusing on culture, team problem solving and conflict resolution in the technical workplace. Process for developing and content of curricular changes will be reported.

The effectiveness of the case method as an instructional technique in improving technical writing was evaluated. The development of a self-report instrument that attempts to measure changes in attitude toward technical communication and the presentation results change are the purpose of this paper. Standards for developing a case set forth by Goldstein and Couture, were used to design an evaluation instrument to measure the effect instruction on student attitude toward technical communication. This self-report instrument is based on model developed and tested by Daly and Miller who studied writer attitude and apprehension toward writing. It was the most important objective of any evaluation is to provide information for improving the program.

Inclusive practices for children and youths with communication disorders. Ad Hoc Committee on Inclusion for students with Communication Disorders.

PubMed

1996-01-01

An array of inclusive service delivery models is recommended for the implementation of services to children and youths with communication disorders. Inclusive practices are intervention services that are based on the unique and specific needs of the individual, and provided in a context that is least restrictive. There are a variety of models through which inclusive practices can be provided, including a direct (pull-out) program, in classroom-based service delivery, community-based models, and consultative interventions. These models should be seen as flexible options that may change depending on student needs. The speech-language pathologist, in collaboration with parents, the student, teachers, support personnel, and administrators, is in the ideal position to decide the model or combination of models that best serves each individual student's communication needs. Implementation of inclusive practices requires consideration of multiple issues, including general education reform, cost effectiveness, and program efficacy. In addition, administrative and school system support, personnel qualifications, staff development, flexible scheduling, and the effects of inclusive practices on all learners need to be considered. At present, available research suggests guarded optimism for the effectiveness of inclusive practices. However, many critical questions have not yet been addressed and additional research is needed to assess the full impact of inclusive practices for students with communication disorders.

An underwater optical wireless communication network

2009-08-01

The growing need for underwater observation and sub-sea monitoring systems has stimulated considerable interest in advancing the enabling technologies of underwater wireless communication and underwater sensor networks. This communication technology is expected to play an important role in investigating climate change, in monitoring biological, bio-geochemical, evolutionary and ecological changes in the sea, ocean and lake environments and in helping to control and maintain oil production facilities and harbors using unmanned underwater vehicles (UUVs), submarines, ships, buoys, and divers. However, the present technology of underwater acoustic communication cannot provide the high data rate required to investigate and monitor these environments and facilities. Optical wireless communication has been proposed as the best alternative to meet this challenge. We present models of three kinds of optical wireless communication links a) a line-of-sight link, b) a modulating retro-reflector link and c) a reflective link, all of which can provide the required data rate. We analyze the link performance based on these models. From the analysis, it is clear that as the water absorption increases, the communication performance decreases dramatically for the three link types. However, by using the scattered lighted it was possible to mitigate this decrease in some cases. We conclude from the analysis that a high data rate underwater optical wireless network is a feasible solution for emerging applications such as UUV to UUV links and networks of sensors, and extended ranges in these applications could be achieved by applying a multi-hop concept.

Revunova, Svetlana; Vlasenko, Vyacheslav; Bukreev, Anatoly

2017-10-01

The article proposes the models of innovative activity development, which is driven by the formation of “points of innovation-driven growth”. The models are based on the analysis of the current state and dynamics of innovative development of construction enterprises in the transport sector and take into account a number of essential organizational and economic changes in management. The authors substantiate implementing such development models as an organizational innovation that has a communication genesis. The use of the communication approach to the formation of “points of innovation-driven growth” allowed the authors to apply the mathematical tools of the graph theory in order to activate the innovative activity of the transport industry in the region. As a result, the authors have proposed models that allow constructing an optimal mechanism for the formation of “points of innovation-driven growth”.

Computer-mediated communication is driving fundamental changes in the nature of written language. We investigate these changes by statistical analysis of a dataset comprising 107 million Twitter messages (authored by 2.7 million unique user accounts). Using a latent vector autoregressive model to aggregate across thousands of words, we identify high-level patterns in diffusion of linguistic change over the United States. Our model is robust to unpredictable changes in Twitter's sampling rate, and provides a probabilistic characterization of the relationship of macro-scale linguistic influence to a set of demographic and geographic predictors. The results of this analysis offer support for prior arguments that focus on geographical proximity and population size. However, demographic similarity – especially with regard to race – plays an even more central role, as cities with similar racial demographics are far more likely to share linguistic influence. Rather than moving towards a single unified “netspeak” dialect, language evolution in computer-mediated communication reproduces existing fault lines in spoken American English. PMID:25409166

Plants limit the range of insect substrate-borne vibratory communication by their architecture and mechanical properties that change transmitted signal time, amplitude and frequency characteristics. Stinkbugs gain higher signal-to-noise ratio and increase communication distance by emitting narrowband low frequency vibratory signals that are tuned with transmission properties of plants. The objective of the present study was to investigate hitherto overlooked consequences of duetting with mutually overlapped narrowband vibratory signals. The overlapped vibrations of the model stinkbug species Eushistus heros, produced naturally or induced artificially on different plants, have been analysed. They represent female and male strategies to preserve information within a complex masked signal. The brown stinkbugs E. heros communicate with species and gender specific vibratory signals that constitute characteristic duets in the calling, courtship and rivalry phases of mating behaviour. The calling female pulse overlaps the male vibratory response when the latency of the latter is shorter than the duration of the female triggering signal or when the male response does not inhibit the following female pulse. Overlapping of signals induces interference that changes their amplitude pattern to a sequence of regularly repeated pulses in which their duration and the difference between frequencies of overlapped vibrations are related inversely. Interference does not occur in overlapped narrow band female calling pulses and broadband male courtship pulse trains. In a duet with overlapped signals females and males change time parameters and increase the frequency difference between signals by changing the frequency level and frequency modulation pattern of their calls.

In recent years, climate impact assessments of relevance to the agricultural and forestry sectors have received considerable attention. Current ecosystem models commonly capture the effect of a warmer climate on biomass production, but they rarely sufficiently capture potential losses caused by pests, pathogens and extreme weather events. In addition, alternative management regimes may not be integrated in the models. A way to improve the quality of climate impact assessments is to increase the science-stakeholder collaboration, and in a two-way dialog link empirical experience and impact modelling with policy and strategies for sustainable management. In this paper we give a brief overview of different ecosystem modelling methods, discuss how to include ecological and management aspects, and highlight the importance of science-stakeholder communication. By this, we hope to stimulate a discussion among the science-stakeholder communities on how to quantify the potential for climate change adaptation by improving the realism in the models.

Change in Surgical Practice for Women With Leiomyomas After the U.S. Food and Drug Administration Morcellator Safety Communication.

To evaluate the association between the U.S. Food and Drug Administration (FDA) communication discouraging use of power morcellators on changes in surgical practice for women with uterine leiomyomas. This is a cross-sectional study using data from 2013 to 2014 in the Healthcare Cost and Utilization Project State Inpatient and State Ambulatory Surgical Databases from Arizona, Florida, Kentucky, and New Jersey. Women with a diagnosis of leiomyomas who underwent hysterectomy or myomectomy were included in the analysis. Multivariable models were used to assess changes in the proportion of hysterectomies performed laparoscopically, vaginally, or by laparotomy in the 15 months before the FDA safety communication in April 2013 (January 2013 to March 2014) to the 9 months after the FDA communication (April to December 2014). Changes in the proportion of women who underwent myomectomy compared with hysterectomy were also evaluated during this time period. There were 77,637 hysterectomy and myomectomy cases analyzed from states with both inpatient and ambulatory surgery data; 59% of patients were outpatients. Overall, there was a 4% (95% CI 3.2-4.8%) decrease in the use of laparoscopic hysterectomy for treatment of uterine leiomyomas from 62% of all hysterectomies before the FDA communication on morcellation to 58% afterward. Changes in surgical practice were more pronounced in the inpatient compared with outpatient setting; inpatient laparoscopic hysterectomy decreased by 7% (95% CI 6.1-7.9%) from 24% to 17% of all hysterectomies with an accompanying increase in abdominal hysterectomy of 8% (95% CI 6.7-8.6%) from 71% to 79%. There were no significant changes in the proportion of women with leiomyomas who underwent myomectomy compared with hysterectomy. The FDA communication discouraging the use of power morcellators was associated with a decline in laparoscopy to perform hysterectomy, particularly in the inpatient setting. There was no change in the selection of myomectomy compared with hysterectomy for leiomyoma treatment after the FDA communication.

Communication, Reasoning, and Planned Behaviors: Unveiling the Effect of Interactive Communication in an Anti-Smoking Social Media Campaign.

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.

Punctuated equilibrium dynamics in human communications

A minimal model based on network incorporating individual interactions is proposed to study the non-Poisson statistical properties of human behavior: individuals in system interact with their neighbors, the probability of an individual acting correlates to its activity, and all the individuals involved in action will change their activities randomly. The model reproduces varieties of spatial-temporal patterns observed in empirical studies of human daily communications, providing insight into various human activities and embracing a range of realistic social interacting systems, particularly, intriguing bimodal phenomenon. This model bridges priority queueing theory and punctuated equilibrium dynamics, and our modeling and analysis is likely to shed light on non-Poisson phenomena in many complex systems.

Children learn language from their parents and then use the acquired system throughout the rest of their life with little change. At least that is commonly assumed. But a recent paper by Galantucci adds to the growing evidence that adults (and children) are able to create and negotiate complex communication systems from scratch and relatively quickly, without a prior model. This raises questions of what cognitive mechanisms are implied in this joint construction of communication systems, and what the implications are for the origins of human language.

The communication of science to the public: A philosophy of television

NASA Astrophysics Data System (ADS)

Carter, Nicholas Brent

The communication of science to the public via the mass media, in particular the televisual format, requires a modified approach to the traditional presumptive models of communicative style. Conventional models of science communication are based on implicit but unexamined assumptions that the most effective and important means of transmission of scientific information are efforts aimed at the attentive segments of the population through specialized and detailed formats. Attempts to reach inattentive audiences with scientific information are customarily unsuccessful or have been deemed unnecessary altogether. The proposed model submits that not only are endeavors to communicate scientific ideas to the disinterested populace of overriding importance but can be quite successful if production styles are altered to reflect more "interest-motivating" designs. A new thrust toward capturing the attention of disinterested audiences before attempting to directly disseminate scientific ideas is proposed. By examining the constraints of both the scientific and communication systems, the model demonstrates that current methods utilized to transmit scientific information are incompatible with the notion of reaching more inattentive audiences. The assumptions of scientific communicators and the community of scientists are critiqued through analysis of the diverse body of research devoted to the public transmission of science and scientific concepts. The foundations of televisual communication are explored and a model of commercial television programming is proffered to redirect classical scientific production methods to more visually interesting, narrative-driven styles. A call to shift focus of scientific communication from the products of science to the process of science is also suggested in part to achieve such a direction. The model proposes that the most important aspect of this process is to begin to show scientists as human beings and the conceptual accessibility of both the scientists and their endeavors. For this to occur, scientists must begin to alter their behaviors and attitudes toward the public dissemination of their research and start by educating themselves on the communicative demands of the media. Communicators must also begin to change their long-held strategies of scientific communication by focusing on the interest factor of their stories before attempting to transmit complicated scientific information.

The increasing size and complexity of US dairy farms could make it more difficult for a veterinary practitioner to effectively communicate protocol recommendations for prevention or treatment on the farm. A continuing education workshop was set up based on the results of research on dairy organizational communication on dairy farms, which resulted in a tool to assess dairy communication structure and flow. The workshop specifically focused on communication structure and whom to talk to when implementing health care changes in calf rearing. In addition, modern methods of veterinary-client communication knowledge and skills were provided. Primary outcomes of the workshops were to obtain feedback from participants about research findings and the communication model, to improve awareness about the complexity of communication structures on dairy farms, and to change participants' knowledge and skills associated with on-farm communication by providing communication theory and skills and an approach to evaluate and improve dairy organizational communication. Of the 37 participants completing the pre-program assessment, most recognized a need for themselves or their practice to improve communication with clients and farm employees. After the program, most participants were confident in their new communication skills and would consider using them. They highlighted specific new ideas they could apply in practice, such as conducting a "communication audit." The results from the assessment of this communication workshop, focused on dairy veterinarians, highlighted the need for communication training in this sector of the profession and practitioners' desire to engage in this type of training.

Communication and social capital in the control of avian influenza: lessons from behaviour change experiences in the Mekong Region.

PubMed

Waisbord, S R; Michaelides, T; Rasmuson, M

2008-01-01

International development agencies, national governments, and nongovernmental organizations are increasingly collaborating with local civil society groups in mounting behaviour change communication (BCC) interventions. Even in countries with weakened civil societies, the social capital of local organizations can be a fundamental communication resource. The experience of three programmes in the Mekong Region that used BCC to prevent and control outbreaks of avian influenza bore out this finding. These programmes worked with the Vietnam Women's Union to mobilize local women as conduits for education; worked with the Centre d'Etude et de Developpement Agricole Cambodgien (CEDAC), in Cambodia, to educate and train village health promoters and model farmers; and worked with the Lao Journalists Association to educate and build skills among print and broadcast journalists to enhance avian influenza coverage. Collaborating with civil society organizations can enhance communication reach, trust, and local ownership, but poses many challenges, particularly institutional capacity. Our experience, nevertheless, holds promise for a measured approach that views social capital as a set of communication resources at the community level that can be mobilized to promote complex behaviours, particularly in a rapidly changing outbreak situation.

Unquestioned answers or unanswered questions: beliefs about science guide responses to uncertainty in climate change risk communication.

PubMed

Rabinovich, Anna; Morton, Thomas A

2012-06-01

In two experimental studies we investigated the effect of beliefs about the nature and purpose of science (classical vs. Kuhnian models of science) on responses to uncertainty in scientific messages about climate change risk. The results revealed a significant interaction between both measured (Study 1) and manipulated (Study 2) beliefs about science and the level of communicated uncertainty on willingness to act in line with the message. Specifically, messages that communicated high uncertainty were more persuasive for participants who shared an understanding of science as debate than for those who believed that science is a search for absolute truth. In addition, participants who had a concept of science as debate were more motivated by higher (rather than lower) uncertainty in climate change messages. The results suggest that achieving alignment between the general public's beliefs about science and the style of the scientific messages is crucial for successful risk communication in science. Accordingly, rather than uncertainty always undermining the effectiveness of science communication, uncertainty can enhance message effects when it fits the audience's understanding of what science is. © 2012 Society for Risk Analysis.

This article uses grounded theory methodology to analyze in-depth interviews conducted with mourners who used social networking sites during bereavement. The social media mourning (SMM) model outlines how social networking sites are used to grieve using one or more of the following: (a) one-way communication, (b) two-way communication, and (c) immortality communication. The model indicates causal conditions of SMM: (a) sharing information with family or friends and (sometimes) beginning a dialog, (b) discussing death with others mourning, (c) discussing death with a broader mourning community, and (d) commemorating and continuing connection to the deceased. The article includes actions and consequences associated with SMM and suggests several ways in which SMM changes or influences the bereavement process.

Conceptual frameworks bring together existing theories and models in order to identify, consolidate, and fill in gaps between theory, practice, and evidence. Given the vast number of possible outcomes that could be studied in genetic counseling, a framework for organizing outcomes and postulating relationships between communication services and genetic counseling outcomes was sought. Through an iterative approach involving literature review, thematic analysis, and consolidation, outcomes and processes were categorized to create and define components of a conceptual framework. The final product, "Framework for Outcomes of Clinical commUnication Services" (FOCUS) contains the following domains: communication strategy; communication process measures; patient care experience, patient changes, patient health; and family changes. A website was created to allow easier access and ongoing modifications to the framework. In addition, a step-by-step guide and two examples were created to show flexibility in how the framework can be used. FOCUS may help in conceptualizing, organizing and summarizing outcomes research related to risk communication and counseling in genetic service delivery as well as other healthcare settings.

2017-05-01

The patient-centered medical home (PCMH) is a model of care that emphasizes the coordination of patient treatment among health care providers. Practice transformation to this model, however, presents a number of challenges. One of these challenges is getting the buy-in of all personnel to commit to making organizational changes in the journey to becoming a nationally recognized medical home. This study investigated internal messages of buy-in as communicated by practices transitioning to this type of care. Grounding itself in stakeholder theory, this study analyzed interviews with staff, administration, and practitioners from 20 medical practices in a mid-Atlantic state. The analysis revealed three overarching themes: (a) communication among staff that is open, consistent; (b) implementation of reinforcement techniques; and (c) access to a change implementer who encourages successful evolution. Discussion of these themes provides recommendations for communication approaches to organizational buy-in for medical practices hoping to become a PCMH.

Being an honest broker of hydrology: Uncovering, communicating and addressing model error in a climate change streamflow dataset

Any model simulation has errors, including errors in meteorological data, process understanding, model structure, and model parameters. These errors may express themselves as bias, timing lags, and differences in sensitivity between the model and the physical world. The evaluation and handling of these errors can greatly affect the legitimacy, validity and usefulness of the resulting scientific product. In this presentation we will discuss a case study of handling and communicating model errors during the development of a hydrologic climate change dataset for the Pacific Northwestern United States. The dataset was the result of a four-year collaboration between the University of Washington, Oregon State University, the Bonneville Power Administration, the United States Army Corps of Engineers and the Bureau of Reclamation. Along the way, the partnership facilitated the discovery of multiple systematic errors in the streamflow dataset. Through an iterative review process, some of those errors could be resolved. For the errors that remained, honest communication of the shortcomings promoted the dataset's legitimacy. Thoroughly explaining errors also improved ways in which the dataset would be used in follow-on impact studies. Finally, we will discuss the development of the "streamflow bias-correction" step often applied to climate change datasets that will be used in impact modeling contexts. We will describe the development of a series of bias-correction techniques through close collaboration among universities and stakeholders. Through that process, both universities and stakeholders learned about the others' expectations and workflows. This mutual learning process allowed for the development of methods that accommodated the stakeholders' specific engineering requirements. The iterative revision process also produced a functional and actionable dataset while preserving its scientific merit. We will describe how encountering earlier techniques' pitfalls allowed us to develop improved methods for scientists and practitioners alike.

Hemodynamic parameters play an important role in aneurysm formation and growth. However, it is difficult to directly observe a rapidly growing de novo aneurysm in a patient. To investigate possible associations between hemodynamic parameters and the formation and growth of intracranial aneurysms, the present study constructed a computational model of a case with an internal carotid artery aneurysm and an anterior communicating artery aneurysm, based on the CT angiography findings of a patient. To simulate the formation of the anterior communicating artery aneurysm and the growth of the internal carotid artery aneurysm, we then constructed a model that virtually removed the anterior communicating artery aneurysm, and a further two models that also progressively decreased the size of the internal carotid artery aneurysm. Computational simulations of the fluid dynamics of the four models were performed under pulsatile flow conditions, and wall shear stress was compared among the different models. In the three aneurysm growth models, increasing size of the aneurysm was associated with an increased area of low wall shear stress, a significant decrease in wall shear stress at the dome of the aneurysm, and a significant change in the wall shear stress of the parent artery. The wall shear stress of the anterior communicating artery remained low, and was significantly lower than the wall shear stress at the bifurcation of the internal carotid artery or the bifurcation of the middle cerebral artery. After formation of the anterior communicating artery aneurysm, the wall shear stress at the dome of the internal carotid artery aneurysm increased significantly, and the wall shear stress in the upstream arteries also changed significantly. These findings indicate that low wall shear stress may be associated with the initiation and growth of aneurysms, and that aneurysm formation and growth may influence hemodynamic parameters in the local and adjacent arteries.

[Attitudes, communication and family planning: a conceptual framework applicable to Rwanda].

An important objective of Rwanda's National Office of Population (ONAPO) is to study psychosocial and cultural variables that encourage or impede family planning use and to define effective communication strategies based on them that can be carried out by ONAPO promoters. The definition and measurement of such variables are discussed in terms of theories of attitude changes and communication. Attitude is a hypothetical construction inferred from opinions and expressive behavior. The concept of attitude has 3 dimensions, the cognitive-evaluative, the affective-emotional, and the behavioral. The affective-emotional dimension is considered the most important by many theoreticians of attitude change. A basic characteristic of attitudes is stability. Communication theory furnishes a model for processes of attitude change, which postulates a source or emitter sending elements of information or messages to a recipient. Feedback from the recipient to the sender allows the efficacy of the message to be assessed and permits the sender to adjust actions until the objective is attained. Feedback is always possible in interpersonal communications between individuals in permanent contact, but becomes more difficult in mass communication. Among the many variables intervening in the formation or change of attitudes toward family planning are sex, age, residence, education, occupation, religion, marital status, and fertility. The psychosocial variables influencing family planning acceptance are at the level of the source, the message, and the recipient. 3 important factors at the level of the source are the credibility, attractiveness, and power or prestige of the source. The message should contain a suggestion that the desired behavior should be adopted and should follow a certain order in presenting information. Factors at the level of the receptor include susceptibility to persuasion, the way in which the message affects the recipient's needs, the selectivity necessary in perceiving the information contained in the message, and the degree of resistance in regard to the message. A 2-stage theory of communication suggests that horizontal communication within small groups is a stronger determinant of attitudes than is verbal communication from authority figures. Communication is the most important factor in all attempts to change attitudes.

Evaluating the use of verbal probability expressions to communicate likelihood information in IPCC reports

NASA Astrophysics Data System (ADS)

Harris, Adam

2014-05-01

The Intergovernmental Panel on Climate Change (IPCC) prescribes that the communication of risk and uncertainty information pertaining to scientific reports, model predictions etc. be communicated with a set of 7 likelihood expressions. These range from "Extremely likely" (intended to communicate a likelihood of greater than 99%) through "As likely as not" (33-66%) to "Extremely unlikely" (less than 1%). Psychological research has investigated the degree to which these expressions are interpreted as intended by the IPCC, both within and across cultures. I will present a selection of this research and demonstrate some problems associated with communicating likelihoods in this way, as well as suggesting some potential improvements.

Objective Although effective HIV prevention interventions have been developed for adolescents, few interventions have explored whether components of the intervention are responsible for the observed changes in behaviors post-intervention. This study examined the mediating role of partner communication frequency on African-American adolescent females’ condom use post-participation in a demonstrated efficacious HIV risk-reduction intervention. Main Outcome Measures Percent condom use in the past 60 days and consistent condom use in the past 6o days across the 12-month follow-up period. Design As part of a randomized controlled trial of African-American adolescent females (N=715), 15-21 years, seeking sexual health services, completed a computerized interview at baseline (prior to intervention) and again 6- and 12-month follow-up post-intervention participation. The interview assessed adolescents’ sexual behavior and partner communication skills, among other variables, at each time point. Using generalized estimating equation (GEE) techniques, both logistic and linear regression models were employed to test mediation over the 12-month follow-up period. Additional tests were conducted to assess the significance of the mediated models. Results Mediation analyses observed that partner communication frequency was a significant partial mediator of both proportion condom-protected sex acts (p =.001) and consistent condom use (p = .001). Conclusion Partner communication frequency, an integral component of this HIV intervention, significantly increased as a function of participating in the intervention partially explaining the change in condom use observed 12-months post-intervention. Understanding what intervention components are associated with behavior change is important for future intervention development. PMID:21843001

Some Good Practices for Integration and Outreach and their Implementation in the Community Integrated Assessment System (CIAS) and its associated web portal CLIMASCOPE

Successful communication of knowledge to climate change policy makers requires the careful integration of scientific knowledge in an integrated assessment that can be clearly communicated to stakeholders, and which encapsulates the uncertainties in the analysis and conveys the need for using a risk assessment approach. It is important that (i) the system is co-designed with the users (ii) relevant disciplines are included (iii) assumptions made are clear (iv) the robustness of outputs to uncertainties is demonstrated (v) the system is flexible so that it can keep up with changing stakeholder needs and (vi) the results are communicated clearly and are readily accessible. The “Community Integrated Assessment System” (CIAS) is a unique multi-institutional, modular, and flexible integrated assessment system for modeling climate change which fulfils the above six criteria. It differs from other integrated models in being a flexible system allowing various combinations of component modules, to be connected together into alternative integrated assessment models. These modules may be written at different institutions in different computer languages and/or based on different operating systems. Scientists are able determine which particular CIAS coupled model they wish to use through a web portal. This includes the facility to implement Latin hypercube experimental design facilitating formal uncertainty analysis. Further exploration of robustness is possible through the ability to select, for example, alternative hyrdrological or climate models to address the same questions. It has been applied to study future scenarios of climate change mitigation, through for example the AVOIDing dangerous climate change project for DEFRA, in which the avoided impacts (benefits) of alternative climate policies were compared to no-policy baselines. These highlight the potential for mitigation to remove a substantial fraction of the climate change impacts that would otherwise occur; but also show that is not possible to avoid all the impacts, and hence that adaptation will still be required. For example, this has been shown for projections of future European drought. CIAS has also been used for analyses used in the IPCC 4AR and the Stern review. Recent applications include a study of the role of avoided deforestation in climate mitigation, and a study of the impacts of climate change on biodiversity. A second web portal, CLIMASCOPE, is being developed for use by stakeholders, currently focusing on the needs of adaptation planners. This will benefit communication by allowing a wide range of users free access to regional climate change projections in simple manner, yet one which encourages risk assessment through encapsulation of the uncertainties in climate change projection. Examples of CLIMASCOPE output that is being made available to stakeholders will be shown.

Hiding in plain sight: communication theory in implementation science.

Poor communication among healthcare professionals is a pressing problem, contributing to widespread barriers to patient safety. The word "communication" means to share or make common. In the literature, two communication paradigms dominate: (1) communication as a transactional process responsible for information exchange, and (2) communication as a transformational process responsible for causing change. Implementation science has focused on information exchange attributes while largely ignoring transformational attributes of communication. In this paper, we debate the merits of encompassing both paradigms. We conducted a two-staged literature review searching for the concept of communication in implementation science to understand how communication is conceptualized. Twenty-seven theories, models, or frameworks were identified; only Rogers' Diffusion of Innovations theory provides a definition of communication and includes both communication paradigms. Most models (notable exceptions include Diffusion of Innovations, The Ottawa Model of Research Use, and Normalization Process Theory) describe communication as a transactional process. But thinking of communication solely as information transfer or exchange misrepresents reality. We recommend that implementation science theories (1) propose and test the concept of shared understanding when describing communication, (2) acknowledge that communication is multi-layered, identify at least a few layers, and posit how identified layers might affect the development of shared understanding, (3) acknowledge that communication occurs in a social context, providing a frame of reference for both individuals and groups, (4) acknowledge the unpredictability of communication (and healthcare processes in general), and (5) engage with and draw on work done by communication theorists. Implementation science literature has conceptualized communication as a transactional process (when communication has been mentioned at all), thereby ignoring a key contributor to implementation intervention success. When conceptualized as a transformational process, the focus of communication moves to shared understanding and is grounded in human interactions and the way we go about constructing knowledge. Instead of hiding in plain sight, we suggest explicitly acknowledging the role that communication plays in our implementation efforts. By using both paradigms, we can investigate when communication facilitates implementation, when it does not, and how to improve it so that our implementation and clinical interventions are embraced by clinicians and patients alike.

Communicating personal amnesty: a model for health promotion in an Australian disability context.

Currently pathological and illness-centric policy surrounds the evaluation of the health status of a person experiencing disability. In this research partnerships were built between disability service providers, community development organizations and disability arts organizations to build a translational evaluative methodology prior to implementation of an arts-based workshop that was embedded in a strengths-based approach to health and well-being. The model consisted of three foci: participation in a pre-designed drama-based workshop program; individualized assessment and evaluation of changing health status; and longitudinal analysis of participants changing health status in their public lives following the culmination of the workshop series. Participants (n = 15) were recruited through disability service providers and disability arts organizations to complete a 13-week workshop series and public performance. The study developed accumulative qualitative analysis tools and member-checking methods specific to the communication systems used by individual participants. Principle findings included increased confidence for verbal and non-verbal communicators; increased personal drive, ambition and goal-setting; increased arts-based skills including professional engagements as artists; demonstrated skills in communicating perceptions of health status to private and public spheres. Tangential positive observations were evident in the changing recreational, vocational and educational activities participants engaged with pre- and post- the workshop series; participants advocating for autonomous accommodation and health provision and changes in the disability service staff's culture. The research is an example of translational health methodologies in disability studies. © The Author (2013). Published by Oxford University Press. All rights reserved.

Open Source software and social networks: disruptive alternatives for medical imaging.

PubMed

Ratib, Osman; Rosset, Antoine; Heuberger, Joris

2011-05-01

In recent decades several major changes in computer and communication technology have pushed the limits of imaging informatics and PACS beyond the traditional system architecture providing new perspectives and innovative approach to a traditionally conservative medical community. Disruptive technologies such as the world-wide-web, wireless networking, Open Source software and recent emergence of cyber communities and social networks have imposed an accelerated pace and major quantum leaps in the progress of computer and technology infrastructure applicable to medical imaging applications. This paper reviews the impact and potential benefits of two major trends in consumer market software development and how they will influence the future of medical imaging informatics. Open Source software is emerging as an attractive and cost effective alternative to traditional commercial software developments and collaborative social networks provide a new model of communication that is better suited to the needs of the medical community. Evidence shows that successful Open Source software tools have penetrated the medical market and have proven to be more robust and cost effective than their commercial counterparts. Developed by developers that are themselves part of the user community, these tools are usually better adapted to the user's need and are more robust than traditional software programs being developed and tested by a large number of contributing users. This context allows a much faster and more appropriate development and evolution of the software platforms. Similarly, communication technology has opened up to the general public in a way that has changed the social behavior and habits adding a new dimension to the way people communicate and interact with each other. The new paradigms have also slowly penetrated the professional market and ultimately the medical community. Secure social networks allowing groups of people to easily communicate and exchange information is a new model that is particularly suitable for some specific groups of healthcare professional and for physicians. It has also changed the expectations of how patients wish to communicate with their physicians. Emerging disruptive technologies and innovative paradigm such as Open Source software are leading the way to a new generation of information systems that slowly will change the way physicians and healthcare providers as well as patients will interact and communicate in the future. The impact of these new technologies is particularly effective in image communication, PACS and teleradiology. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

An Ecological Framework for Cancer Communication: Implications for Research

PubMed Central

Intille, Stephen S; Zabinski, Marion F

2005-01-01

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

Physical inactivity accounts for more than 3 million deaths per year, most from non-communicable diseases in low-income and middle-income countries. We used reviews of physical activity interventions and a simulation model to examine how megatrends in information and communication technology and transportation directly and indirectly affect levels of physical activity across countries of low, middle, and high income. The model suggested that the direct and potentiating eff ects of information and communication technology, especially mobile phones, are nearly equal in magnitude to the mean eff ects of planned physical activity interventions. The greatest potential to increase population physical activity might thus be in creation of synergistic policies in sectors outside health including communication and transportation. However, there remains a glaring mismatch between where studies on physical activity interventions are undertaken and where the potential lies in low-income and middle-income countries for population-level effects that will truly affect global health.

2018-04-19

How can we use stories from other people to promote better health experiences, improve judgments about health, and increase the quality of medical decisions without introducing bias, systematically persuading the listeners to change their attitudes, or altering behaviors in nonoptimal ways? More practically, should narratives be used in health education, promotion, or behavior change interventions? In this article, we address these questions by conducting a narrative review of a diverse body of literature on narratives from several disciplines to gain a better understanding about what narratives do, including their role in communication, engagement, recall, persuasion, and health behavior change. We also review broad theories about information processing and persuasion from psychology and more specific models about narrative messaging found in the health communication and marketing literatures to provide insight into the processes by which narratives have their effect on health behavior. To address major gaps in our theoretical understanding about how narratives work and what effects they will have on health behavior, we propose the Narrative Immersion Model, whose goal is to identify the parameters that predict the specific impact of a particular narrative (e.g. persuade, inform, comfort, etc.) based on the type of narrative message (e.g. process, experience, or outcome narrative). Further, the Narrative Immersion Model describes the magnitude of the effect as increasing through successive layers of engagement with the narrative: interest, identification, and immersion. Finally, the Narrative Immersion Model identifies characteristics of the narrative intervention that encourage greater immersion within a given narrative. We believe there are important communication gaps in areas areas of behavioral medicine that could be addressed with narratives; however, more work is needed in order to employ narrative messaging systematically. The Narrative Immersion Model advances our theoretical understanding about narrative processing and its subsequent effects on knowledge, attitudes, and behavior.

Gap between science and media revisited: Scientists as public communicators

PubMed Central

Peters, Hans Peter

2013-01-01

The present article presents an up-to-date account of the current media relations of scientists, based on a comprehensive analysis of relevant surveys. The evidence suggests that most scientists consider visibility in the media important and responding to journalists a professional duty—an attitude that is reinforced by universities and other science organizations. Scientific communities continue to regulate media contacts with their members by certain norms that compete with the motivating and regulating influences of public information departments. Most scientists assume a two-arena model with a gap between the arenas of internal scientific and public communication. They want to meet the public in the public arena, not in the arena of internal scientific communication. Despite obvious changes in science and in the media system, the orientations of scientists toward the media, as well as the patterns of interaction with journalists, have their roots in the early 1980s. Although there is more influence on public communication from the science organizations and more emphasis on strategic considerations today, the available data do not indicate abrupt changes in communication practices or in the relevant beliefs and attitudes of scientists in the past 30 y. Changes in the science–media interface may be expected from the ongoing structural transformation of the public communication system. However, as yet, there is little evidence of an erosion of the dominant orientation toward the public and public communication within the younger generation of scientists. PMID:23940312

Vocal Development as a Guide to Modeling the Evolution of Language.

PubMed

Oller, D Kimbrough; Griebel, Ulrike; Warlaumont, Anne S

2016-04-01

Modeling of evolution and development of language has principally utilized mature units of spoken language, phonemes and words, as both targets and inputs. This approach cannot address the earliest phases of development because young infants are unable to produce such language features. We argue that units of early vocal development-protophones and their primitive illocutionary/perlocutionary forces-should be targeted in evolutionary modeling because they suggest likely units of hominin vocalization/communication shortly after the split from the chimpanzee/bonobo lineage, and because early development of spontaneous vocal capability is a logically necessary step toward vocal language, a root capability without which other crucial steps toward vocal language capability are impossible. Modeling of language evolution/development must account for dynamic change in early communicative units of form/function across time. We argue for interactive contributions of sender/infants and receiver/caregivers in a feedback loop involving both development and evolution and propose to begin computational modeling at the hominin break from the primate communicative background.

HIV communication capacity strengthening: a critical review.

Lettenmaier, Cheryl; Kraft, Joan Marie; Raisanen, Keris; Serlemitsos, Elizabeth

2014-08-15

HIV communication is most effective and sustainable when it is designed and implemented locally and tailored to the local context. This requires capacity strengthening at national, subnational, and community levels. Through a review of the published and selected "grey" literature, we examine HIV communication capacity strengthening: definitions, measurements, implementation, and effects. We found limited documentation of HIV communication capacity needs or systematic approaches to address them. Most HIV communication capacity strengthening to date has focused on building individual competencies to design and manage social and behavior change communication programs through training courses, often coupled with networking opportunities for participants, post-training mentoring, and technical assistance. A few of these efforts have been evaluated through pre- and post-training tests and qualitative interviews with participants and have shown potential for improvement in individual skills and knowledge. Health communication capacity assessment tools that measure individual and organizational competencies exist, but they have most often been used to identify capacity building needs, not for evaluating capacity strengthening efforts. A new definition of capacity strengthening, grown out of recent efforts to improve effectiveness of international health and development programs, focuses on improving organizational and societal systems that support performance and individual competencies. We propose a holistic model for HIV communication capacity strengthening and call for rigorous documentation and evaluation to determine and scale-up optimal capacity building interventions for strengthening social and behavior change communication for HIV prevention, care, and treatment in developing countries.

Non-verbal referential communication is impaired in children with Autism Spectrum Disorders (ASD). However, the development of difficulties with referential communication in the younger siblings of children with ASD (High-Risk Siblings)—and the degree to which early referential communication predicts later autism symptomatology—is not clear. We modeled the early developmental trajectories of three types of referential communication: responding to joint attention (RJA), initiating joint attention (IJA), and initiating behavioral requests (IBR) across 8, 10, 12, 15, and18 months of age in High-Risk Siblings (n = 40) and the infant siblings of children without ASD (Low-Risk Siblings; n = 21). Hierarchical Linear Modeling indicated that High-Risk Siblings exhibited lower levels of baseline RJA and IJA and a lower rate of linear change in IBR than Low-Risk Siblings. When the 10 High-Risk Siblings who received an ASD diagnosis were excluded from analyses, group differences in the development of referential communication remained significant only for RJA. Baseline levels of IJA were associated with later ASD symptomatology among High-Risk Siblings, suggesting that individual differences in referential communication development at 8 months may index early manifestations of ASD.

Research studies involving health-related online communities have focused on examining network structure to understand mechanisms underlying behavior change. Content analysis of the messages exchanged in these communities has been limited to the "social support" perspective. However, existing behavior change theories suggest that message content plays a prominent role reflecting several sociocognitive factors that affect an individual's efforts to make a lifestyle change. An understanding of these factors is imperative to identify and harness the mechanisms of behavior change in the Health 2.0 era. The objective of this work is two-fold: (1) to harness digital communication data to capture essential meaning of communication and factors affecting a desired behavior change, and (2) to understand the applicability of existing behavior change theories to characterize peer-to-peer communication in online platforms. In this paper, we describe grounded theory-based qualitative analysis of digital communication in QuitNet, an online community promoting smoking cessation. A database of 16,492 de-identified public messages from 1456 users from March 1-April 30, 2007, was used in our study. We analyzed 795 messages using grounded theory techniques to ensure thematic saturation. This analysis enabled identification of key concepts contained in the messages exchanged by QuitNet members, allowing us to understand the sociobehavioral intricacies underlying an individual's efforts to cease smoking in a group setting. We further ascertained the relevance of the identified themes to theoretical constructs in existing behavior change theories (eg, Health Belief Model) and theoretically linked techniques of behavior change taxonomy. We identified 43 different concepts, which were then grouped under 12 themes based on analysis of 795 messages. Examples of concepts include "sleepiness," "pledge," "patch," "spouse," and "slip." Examples of themes include "traditions," "social support," "obstacles," "relapse," and "cravings." Results indicate that themes consisting of member-generated strategies such as "virtual bonfires" and "pledges" were related to the highest number of theoretical constructs from the existing behavior change theories. In addition, results indicate that the member-generated communication content supports sociocognitive constructs from more than one behavior change model, unlike the majority of the existing theory-driven interventions. With the onset of mobile phones and ubiquitous Internet connectivity, online social network data reflect the intricacies of human health behavior as experienced by health consumers in real time. This study offers methodological insights for qualitative investigations that examine the various kinds of behavioral constructs prevalent in the messages exchanged among users of online communities. Theoretically, this study establishes the manifestation of existing behavior change theories in QuitNet-like online health communities. Pragmatically, it sets the stage for real-time, data-driven sociobehavioral interventions promoting healthy lifestyle modifications by allowing us to understand the emergent user needs to sustain a desired behavior change.

Forecasted Impact of Climate Change on Infectious Disease and Health Security in Hawaii by 2050.

PubMed

Canyon, Deon V; Speare, Rick; Burkle, Frederick M

2016-12-01

Climate change is expected to cause extensive shifts in the epidemiology of infectious and vector-borne diseases. Scenarios on the effects of climate change typically attribute altered distribution of communicable diseases to a rise in average temperature and altered incidence of infectious diseases to weather extremes. Recent evaluations of the effects of climate change on Hawaii have not explored this link. It may be expected that Hawaii's natural geography and robust water, sanitation, and health care infrastructure renders residents less vulnerable to many threats that are the focus on smaller, lesser developed, and more vulnerable Pacific islands. In addition, Hawaii's communicable disease surveillance and response system can act rapidly to counter increases in any disease above baseline and to redirect resources to deal with changes, particularly outbreaks due to exotic pathogens. The evidence base examined in this article consistently revealed very low climate sensitivity with respect to infectious and mosquito-borne diseases. A community resilience model is recommended to increase adaptive capacity for all possible climate change impacts rather an approach that focuses specifically on communicable diseases.

Adults with cerebral palsy (CP) experience multiple, functional changes as they age, including changes to communication modes and methods that enable development and maintenance of relationships, communicative participation and quality-of-life. Little is known about the nature of communication changes experienced by this group. The aim of this study was to better understand how adults with CP experience changes in their communication abilities as they age and the subsequent psychosocial impact. Twenty adults with cerebral palsy aged 40-72 years with complex communication needs (CCN) participated in a series of in-depth interviews, framing their experiences of loss and grief throughout their lives. The impact of changing communication abilities emerged as an important area of focus. Data were analysed using constructivist grounded theory methodology. Themes arising from the participants' perceptions of their communication included experiencing communication change as a loss with subsequent impact on self-concept; and how communication is integral to the process of managing losses associated with older age. Implications for speech-language pathologists working with older people with cerebral palsy and CCN include the need to understand the psychosocial impact of communication changes on social interaction, relationships and communicative participation. It is important to promote positive and meaningful communication options that maintain a coherent sense of self in addition to promoting functional communication skills and communicative participation.

OBJECTIVE Cancer patients and partners often report inadequate communication about illness-related issues, although it is essential for mutual support and informal caregiving. This study examined the patterns of change in dyadic communication between patients with prostate cancer and their partners, and also determined if certain factors affected their communication over time. METHOD Using multilevel modeling, this study analyzed longitudinal data obtained from a randomized clinical trial with prostate cancer patients and their partners, to examine their communication over time. Patients and partners (N=134 pairs) from the usual-care control group independently completed baseline demographic assessment and measures of social support, uncertainty, symptom distress, and dyadic communication at baseline, and 4-, 8-, and 12-month follow-ups. RESULTS The results indicated that (1) patients and partners reported similar levels of open communication at the time of diagnosis. Communication reported by patients and partners decreased over time in a similar trend, regardless of phase of illness; (2) phase of illness affected couples’ open communication at diagnosis but not patterns of change over time; and (3) couples’ perceived communication increased as they reported more social support, less uncertainty, and fewer hormonal symptoms in patients. Couples’ demographic factors and general symptoms, and patients’ prostate cancer-specific symptoms did not affect their levels of open communication. CONCLUSIONS Perceived open communication between prostate cancer patients and partners over time is affected by certain baseline and time-varying psychosocial and cancer-related factors. The results provide empirical evidence that may guide the development of strategies to facilitate couples’ interaction and mutual support during survivorship. PMID:20967920

The essential interactions between understanding climate variability and climate change

NASA Astrophysics Data System (ADS)

Neelin, J. D.

2017-12-01

Global change is sometimes perceived as a field separate from other aspects of atmospheric and oceanic sciences. Despite the long history of communication between the scientific communities studying global change and those studying interannual variability and weather, increasing specialization and conflicting societal demands on the fields can put these interactions at risk. At the same time, current trajectories for greenhouse gas emissions imply substantial adaptation to climate change will be necessary. Instead of simply projecting effects to be avoided, the field is increasingly being asked to provide regional-level information for specific adaptation strategies—with associated requirements for increased precision on projections. For extreme events, challenges include validating models for rare events, especially for events that are unprecedented in the historical record. These factors will be illustrated with examples of information transfer to climate change from work on fundamental climate processes aimed originally at timescales from hours to interannual. Work to understand the effects that control probability distributions of moisture, temperature and precipitation in historical weather can yield new factors to examine for the changes in the extremes of these distributions under climate change. Surprisingly simple process models can give insights into the behavior of vastly more complex climate models. Observation systems and model ensembles aimed at weather and interannual variations prove valuable for global change and vice versa. Work on teleconnections in the climate system, such as the remote impacts of El Niño, is informing analysis of projected regional rainfall change over California. Young scientists need to prepare to work across the full spectrum of climate variability and change, and to communicate their findings, as they and our society head for future that is more interesting than optimal.

Few studies have assessed the efficacy of communication skills training for postgraduate physician trainees at the level of behaviors. We designed a residential communication skills workshop (Oncotalk) for medical oncology fellows. The intervention design built on existing successful models by teaching specific communication tasks linked to the patient's trajectory of illness. This study evaluated the efficacy of Oncotalk in changing observable communication behaviors. Oncotalk was a 4-day residential workshop emphasizing skills practice in small groups. This preintervention and postintervention cohort study involved 115 medical oncology fellows from 62 different institutions during a 3-year study. The primary outcomes were observable participant communication skills measured during standardized patient encounters before and after the workshop in giving bad news and discussing transitions to palliative care. The standardized patient encounters were audiorecorded and assessed by blinded coders using a validated coding system. Before-after comparisons were made using each participant as his or her own control. Compared with preworkshop standardized patient encounters, postworkshop encounters showed that participants acquired a mean of 5.4 bad news skills (P<.001) and a mean of 4.4 transitions skills (P<.001). Most changes in individual skills were substantial; for example, in the bad news encounter, 16% of participants used the word "cancer" when giving bad news before the workshop, and 54% used it after the workshop (P<.001). Also in the bad news encounter, blinded coders were able to identify whether a standardized patient encounter occurred before or after the workshop in 91% of the audiorecordings. Oncotalk represents a successful teaching model for improving communication skills for postgraduate medical trainees.

Simulation of Controller Pilot Data Link Communications over VHF Digital Link Mode 3

The Federal Aviation Administration (FAA) has established an operational plan for the future Air Traffic Management (ATM) system, in which the Controller Pilot Data Link Communications (CPDLC) is envisioned to evolve into digital messaging that will take on an ever increasing role in controller to pilot communications, significantly changing the way the National Airspace System (NAS) is operating. According to FAA, CPDLC represents the first phase of the transition from the current analog voice system to an International Civil Aviation Organization (ICAO) compliant system in which digital communication becomes the alternate and perhaps primary method of routine communication. The CPDLC application is an Air Traffic Service (ATS) application in which pilots and controllers exchange messages via an addressed data link. CPDLC includes a set of clearance, information, and request message elements that correspond to existing phraseology employed by current Air Traffic Control (ATC) procedures. These message elements encompass altitude assignments, crossing constraints, lateral deviations, route changes and clearances, speed assignments, radio frequency assignments, and various requests for information. The pilot is provided with the capability to respond to messages, to request clearances and information, to report information, and to declare/rescind an emergency. A 'free text' capability is also provided to exchange information not conforming to defined formats. This paper presents simulated results of the aeronautical telecommunication application Controller Pilot Data Link Communications over VHF Digital Link Mode 3 (VDL Mode 3). The objective of this simulation study was to determine the impact of CPDLC traffic loads, in terms of timely message delivery and capacity of the VDL Mode 3 subnetwork. The traffic model is based on and is used for generating air/ground messages with different priorities. Communication is modeled for the en route domain of the Cleveland Center air traffic (ZOB ARTCC).

2016-10-01

The aim of this study was to use Kotter's leading change model to explore the implementation of workplace health and wellbeing initiatives. Qualitative interviews were conducted with 31 workplace representatives with a healthy workplace initiative. None of the workplaces used a formal change management model when implementing their healthy workplace initiatives. Not all of the steps in Kotter model were considered necessary and the order of the steps was challenged. For example, interviewees perceived that communicating the vision, developing the vision, and creating a guiding coalition were integral parts of the process, although there was less emphasis on the importance of creating a sense of urgency and consolidating change. Although none of the workplaces reported using a formal organizational change model when implementing their healthy workplace initiatives, there did appear to be perceived merit in using the steps in Kotter's model.

Specification and misspecification of theoretical foundations and logic models for health communication campaigns.

PubMed

Slater, Michael D

2006-01-01

While increasingly widespread use of behavior change theory is an advance for communication campaigns and their evaluation, such theories provide a necessary but not sufficient condition for theory-based communication interventions. Such interventions and their evaluations need to incorporate theoretical thinking about plausible mechanisms of message effect on health-related attitudes and behavior. Otherwise, strategic errors in message design and dissemination, and misspecified campaign logic models, insensitive to campaign effects, are likely to result. Implications of the elaboration likelihood model, attitude accessibility, attitude to the ad theory, exemplification, and framing are explored, and implications for campaign strategy and evaluation designs are briefly discussed. Initial propositions are advanced regarding a theory of campaign affect generalization derived from attitude to ad theory, and regarding a theory of reframing targeted health behaviors in those difficult contexts in which intended audiences are resistant to the advocated behavior or message.

Modeling node bandwidth limits and their effects on vector combining algorithms

DOE Office of Scientific and Technical Information (OSTI.GOV)

Littlefield, R.J.

Each node in a message-passing multicomputer typically has several communication links. However, the maximum aggregate communication speed of a node is often less than the sum of its individual link speeds. Such computers are called node bandwidth limited (NBL). The NBL constraint is important when choosing algorithms because it can change the relative performance of different algorithms that accomplish the same task. This paper introduces a model of communication performance for NBL computers and uses the model to analyze the overall performance of three algorithms for vector combining (global sum) on the Intel Touchstone DELTA computer. Each of the threemore » algorithms is found to be at least 33% faster than the other two for some combinations of machine size and vector length. The NBL constraint is shown to significantly affect the conditions under which each algorithm is fastest.« less

Electronic health record tools' support of nurses' clinical judgment and team communication.

Nurses need to quickly process information to form clinical judgments, communicate with the healthcare team, and guide optimal patient care. Electronic health records not only offer potential for enhanced care but also introduce unintended consequences through changes in workflow, clinical judgment, and communication. We investigated nurses' use of improvised (self-made) and electronic health record-generated cognitive artifacts on clinical judgment and team communication. Tanner's Clinical Judgment Model provided a framework and basis for questions in an online survey and focus group interviews. Findings indicated that (1) nurses rated self-made work lists and medication administration records highest for both clinical judgment and communication, (2) tools aided different dimensions of clinical judgment, and (3) interdisciplinary tools enhance team communication. Implications are that electronic health record tool redesign could better support nursing work.

Growth curve models examined changes in adolescent self-reported parent-child communication conditional on family meal frequency over a 3.5 year period among a population of racially-diverse, low-income adolescents from an urban environment (n = 4750). Results indicated that although both family dinner frequency and adolescent perceptions of parent-child communication scores were characterized by negative linear growth over time (both p < .0001), family dinner frequency was positively associated with adolescent perceptions of parent-child communication scores over time (p < .0001). Study findings suggest that families with teenagers may enhance parent-child communication and ultimately promote healthy adolescent development by making family dinner a priority. Additionally, the communication benefits of family dinner at the beginning of 6th grade may be protective through 8th grade. PMID:20545399

A Pathophysiological Model-Driven Communication for Dynamic Distributed Medical Best Practice Guidance Systems.

Hosseini, Mohammad; Jiang, Yu; Wu, Poliang; Berlin, Richard B; Ren, Shangping; Sha, Lui

2016-11-01

There is a great divide between rural and urban areas, particularly in medical emergency care. Although medical best practice guidelines exist and are in hospital handbooks, they are often lengthy and difficult to apply clinically. The challenges are exaggerated for doctors in rural areas and emergency medical technicians (EMT) during patient transport. In this paper, we propose the concept of distributed executable medical best practice guidance systems to assist adherence to best practice from the time that a patient first presents at a rural hospital, through diagnosis and ambulance transfer to arrival and treatment at a regional tertiary hospital center. We codify complex medical knowledge in the form of simplified distributed executable disease automata, from the thin automata at rural hospitals to the rich automata in the regional center hospitals. However, a main challenge is how to efficiently and safely synchronize distributed best practice models as the communication among medical facilities, devices, and professionals generates a large number of messages. This complex problem of patient diagnosis and transport from rural to center facility is also fraught with many uncertainties and changes resulting in a high degree of dynamism. A critically ill patient's medical conditions can change abruptly in addition to changes in the wireless bandwidth during the ambulance transfer. Such dynamics have yet to be addressed in existing literature on telemedicine. To address this situation, we propose a pathophysiological model-driven message exchange communication architecture that ensures the real-time and dynamic requirements of synchronization among distributed emergency best practice models are met in a reliable and safe manner. Taking the signs, symptoms, and progress of stroke patients transported across a geographically distributed healthcare network as the motivating use case, we implement our communication system and apply it to our developed best practice automata using laboratory simulations. Our proof-of-concept experiments shows there is potential for the use of our system in a wide variety of domains.

Hughes, Anne K; Lewinson, Terri D W

Many women experience changes in sexual health as they age, and discussing these changes with health care providers is an essential component of optimal health management. The purpose of this study was to understand aging women's perspectives about communicating with providers about sexual health. We used the integrative model of behavioral prediction as a theoretical lens to explore women's attitudes, perceived norms, and perceived self-efficacy that promote or inhibit the likelihood of communicating about sexual health. In this theory-based qualitative study, we interviewed 28 community-dwelling older women in the Midwestern United States. Through thematic analysis, we identified both positive and negative attitudes about communicating with providers. Women seemed most inclined to discuss sexual health if they perceived that important patient-provider conditions, such as trust and rapport, were in place. Despite situational obstacles and perceived norms, these women held strong beliefs about their abilities to discuss sexual health topics with providers. © The Author(s) 2014.

Attachment based treatments for adolescents: the secure cycle as a framework for assessment, treatment and evaluation.

2015-01-01

The emergence of attachment-based treatments (ABTs) for adolescents highlights the need to more clearly define and evaluate these treatments in the context of other attachment based treatments for young children and adults. We propose a general framework for defining and evaluating ABTs that describes the cyclical processes that are required to maintain a secure attachment bond. This secure cycle incorporates three components: (1) the child or adult's IWM of the caregiver; (2) emotionally attuned communication; and (3) the caregiver's IWM of the child or adult. We briefly review Bowlby, Ainsworth, and Main's contributions to defining the components of the secure cycle and discuss how this framework can be adapted for understanding the process of change in ABTs. For clinicians working with adolescents, our model can be used to identify how deviations from the secure cycle (attachment injuries, empathic failures and mistuned communication) contribute to family distress and psychopathology. The secure cycle also provides a way of describing the ABT elements that have been used to revise IWMs or improve emotionally attuned communication. For researchers, our model provides a guide for conceptualizing and measuring change in attachment constructs and how change in one component of the interpersonal cycle should generalize to other components.

Spatial heterogeneity of climate change as an experiential basis for skepticism

2017-01-01

We postulate that skepticism about climate change is partially caused by the spatial heterogeneity of climate change, which exposes experiential learners to climate heuristics that differ from the global average. This hypothesis is tested by formalizing an index that measures local changes in climate using station data and comparing this index with survey-based model estimates of county-level opinion about whether global warming is happening. Results indicate that more stations exhibit cooling and warming than predicted by random chance and that spatial variations in these changes can account for spatial variations in the percentage of the population that believes that “global warming is happening.” This effect is diminished in areas that have experienced more record low temperatures than record highs since 2005. Together, these results suggest that skepticism about climate change is driven partially by personal experiences; an accurate heuristic for local changes in climate identifies obstacles to communicating ongoing changes in climate to the public and how these communications might be improved.

High-Throughput Analysis of Age-Dependent Protein Changes in Layer II/III of the Human Orbitofrontal Cortex

NASA Astrophysics Data System (ADS)

Kapadia, Fenika

Studies on the orbitofrontal cortex (OFC) during normal aging have shown a decline in cognitive functions, a loss of spines/synapses in layer III and gene expression changes related to neural communication. Biological changes during the course of normal aging are summarized into 9 hallmarks based on aging in peripheral tissue. Whether these hallmarks apply to non-dividing brain tissue is not known. Therefore, we opted to perform large-scale proteomic profiling of the OFC layer II/III during normal aging from 15 young and 18 old male subjects. MaxQuant was utilized for label-free quantification and statistical analysis by the Random Intercept Model (RIM) identified 118 differentially expressed (DE) age-related proteins. Altered neural communication was the most represented hallmark of aging (54% of DE proteins), highlighting the importance of communication in the brain. Functional analysis showed enrichment in GABA/glutamate signaling and pro-inflammatory responses. The former may contribute to alterations in excitation/inhibition, leading to cognitive decline during aging.

Opinion dynamics is studied through a minimal Ising model with three main influences (fields): personal conservatism (power-law distributed), inter-personal and group pressure, and a global field incorporating peer-to-peer and mass communications, which is generated bottom-up from the faction supporting the new opinion. A rich phase diagram appears separating possible terminal stages of the opinion diffusion, characterizing failure phases by the features of the individuals who had changed their opinion. An exhaustive solution of the model is produced, allowing predictions to be made on the opinion’s assimilation in the society.

2015-01-01

Furthering our understanding of how communication can improve end-of-life decision making requires a shift in focus from whether people talk to how people talk about end-of-life health decisions. This study used communication accommodation theory to examine the extent to which communication nonaccommodation distinguished more from less successful end-of-life conversations among family members. We analyzed elicited conversations about end-of-life health decisions from 121 older parent/adult child dyads using outside ratings of communication over- and underaccommodation and self-reported conversational outcomes. Results of multilevel linear modeling revealed that outside ratings of underaccommodation predicted self-reported and partner-reported uncertainty, and ratings of overaccommodation predicted self-reported decision-making efficacy and change in concordance accuracy. We discuss the methodological, theoretical, and practical implications of these findings.

Communication and marketing are rapidly becoming recognized as core functions, or core competencies, in the field of public health. Although these disciplines have fostered considerable academic inquiry, a coherent sense of precisely how these disciplines can inform the practice of public health has been slower to emerge. In this article we propose a framework--based on contemporary ecological models of health--to explain how communication and marketing can be used to advance public health objectives. The framework identifies the attributes of people (as individuals, as social networks, and as communities or populations) and places that influence health behaviors and health. Communication, i.e., the provision of information, can be used in a variety of ways to foster beneficial change among both people (e.g., activating social support for smoking cessation among peers) and places (e.g., convincing city officials to ban smoking in public venues). Similarly, marketing, i.e., the development, distribution and promotion of products and services, can be used to foster beneficial change among both people (e.g., by making nicotine replacement therapy more accessible and affordable) and places (e.g., by providing city officials with model anti-tobacco legislation that can be adapted for use in their jurisdiction). Public health agencies that use their communication and marketing resources effectively to support people in making healthful decisions and to foster health-promoting environments have considerable opportunity to advance the public's health, even within the constraints of their current resource base.

This study examined the mass media and personal characteristics leading to health communication inequality as well as the role of certain factors in health communication's mass media process. Using both sociodemographic variables and Maletzke's model as a basis, we investigated the relationship between selected components of the mass communication process, the receiving of reliable health information as a result of health communication, and the condition of its use. The study involved 1853 people in Turkey and was structured in two parts. The first part dealt with questions regarding sociodemographic characteristics, the use of the mass media and the public's ability to obtain health information from it, the public's perception of the trustworthiness of health information, and the state of translating this information into health-promoting behaviours. In the second part, questions related to the mass communication process were posed using a five-point Likert scale. This section tried to establish structural equation modelling using the judgements prepared on the basis of the mass media model. Through this study, it has been observed that sociodemographic factors such as education and age affect individuals' use of and access to communication channels; individuals' trust in and selection of health information from the programme content and their changing health behaviours (as a result of the health information) are related to both their perception of the mass communication process and to sociodemographic factors, but are more strongly related to the former. © The Author(s) 2014.

Background Communication training is a central part of medical education. The aim of this article is to explore the positions and didactic functions of the fourth wall in medical communication training, using a role-play model basically similar to a theatrical performance. Method The empirical data stem from a communication training model demonstrated at an international workshop for medical teachers and course organizers. The model involves an actress playing a patient, students alternating in the role of the doctor, and a teacher who moderates. The workshop was videotaped and analyzed qualitatively. Results The analysis of the empirical material revealed three main locations of the fourth wall as it moved and changed qualities during the learning session: 1) A traditional theatre location, where the wall was transparent for the audience, but opaque for the participants in the fiction. 2) A "timeout/reflection" location, where the wall was doubly opaque, for the patient on the one side and the moderator, the doctor and the audience on the other side and 3) an "interviewing the character" location where the wall enclosed everybody in the room. All three locations may contribute to the learning process. Conclusion The theatrical concept 'the fourth wall' may present an additional tool for new understanding of fiction based communication training. Increased understanding of such an activity may help medical teachers/course organizers in planning and evaluating communication training courses. PMID:17040575

New web technologies and task specific software packages and services are fundamentally changing the way we share, collect, visualise, communicate and distribute geographic information. Coupled with these new technologies is the emergence of rich fine scale and extensive geographical datasets of the built environment. Such technologies and data are providing opportunities for both the social and physical sciences that were unimaginable ten years ago. Within this paper we discus such change from our own experiences at the Centre of Advanced Spatial Analysis. Specifically, how it is now possible to harness the crowd to collect peoples’ opinions about topical events such as the current financial crisis, in real time and map the results, through the use of our GMapCreator software and the MapTube website. Furthermore, such tools allow for widespread dissemination and visualisation of geographic data to whoever has an internet connection. We will explore how one can use new datasets to visualise the city using our Virtual London model as an example. Within the model individual buildings are tagged with multiple attributes providing a lens to explore the urban structure offering a plethora of research applications. We then turn to how one can visualise and communicate such data through low cost software and virtual worlds such as Crysis and Second Life with a look into their potential for modelling and finally how we disseminated much of this information through weblogs (blogs) such as Digital Urban, GIS and Agent-based modelling and Urban Tick.

Communication skills training for general practitioners to promote patient coping: the GRIP approach.

2009-07-01

To develop, perform and test the effects of a communication skills training program for general practitioners (GPs). The program specifically addresses the patients' coping and resources despite more or less severe psychological or physical illness. A training model was developed, based on cognitive therapy and solution-focused therapy. The training was given the acronym GRIP after its main content: Get a measure of the patient's subjective complaints and illness attributions. Respond to the patient's understanding of the complaints. Identify resources and solutions. Promote positive coping. The study involved a quasi-experimental design in which 266 consultations with 25 GPs were video recorded. Forty hours of communication skills training were given to the intervention group. Consultation duration, patient age and distress determined the frequency of the GRIP communication. There was a significant effect of training on four particular subcategories of the GRIP techniques. The effect of the training was most evident in a subgroup of GPs who used little or no resource-oriented communication before training. This pilot training model may help change the GPs' communicative pattern with patients in some situations. Communication skills training programmes that emphasize patient attributions and personal resources should be developed further and tested in general practice settings with an aim to promote patient coping.

The Role of Interpersonal Relations in Healthcare Team Communication and Patient Safety: A Proposed Model of Interpersonal Process in Teamwork.

Lee, Charlotte Tsz-Sum; Doran, Diane Marie

2017-06-01

Patient safety is compromised by medical errors and adverse events related to miscommunications among healthcare providers. Communication among healthcare providers is affected by human factors, such as interpersonal relations. Yet, discussions of interpersonal relations and communication are lacking in healthcare team literature. This paper proposes a theoretical framework that explains how interpersonal relations among healthcare team members affect communication and team performance, such as patient safety. We synthesized studies from health and social science disciplines to construct a theoretical framework that explicates the links among these constructs. From our synthesis, we identified two relevant theories: framework on interpersonal processes based on social relation model and the theory of relational coordination. The former involves three steps: perception, evaluation, and feedback; and the latter captures relational communicative behavior. We propose that manifestations of provider relations are embedded in the third step of the framework on interpersonal processes: feedback. Thus, varying team-member relationships lead to varying collaborative behavior, which affects patient-safety outcomes via a change in team communication. The proposed framework offers new perspectives for understanding how workplace relations affect healthcare team performance. The framework can be used by nurses, administrators, and educators to improve patient safety, team communication, or to resolve conflicts.

The application of the Practitioners in Applied Practice Model during breaking bad news communication training for medical students: a case study.

PubMed

Dunning, Rose; Laidlaw, Anita

2015-11-01

Breaking bad news is a key skill within clinical communication and one which can impact outcomes for both the patient and practitioner. The evidence base for effective clinical communication training in breaking bad news is scarce. Frameworks have been found to assist the practitioner, such as SPIKES; however, the pedagogical approach used alongside such frameworks can vary. This study sought to examine the impact of utilising the Practitioners in Applied Practice Model (PAPM) alongside the SPIKES framework for training undergraduate medical students in breaking bad news. A case study approach is used to highlight the impact of training based on the PAPM and SPIKES on patient-centred communication and simulated patient satisfaction with the clinical communication behaviour. Results showed that following training, both patient-centred behaviour and patient satisfaction improved. With detailed communication behaviour changes, a balance was established between rapport building behaviour, lifestyle and psychosocial talk alongside biomedical information. This case study shows how the PAPM could be utilised alongside the SPIKES framework to improve breaking bad news communication in medical undergraduate students and describes the behavioural basis of the improvement. Further research is required to show the generalisability of this training intervention. © The Author(s) 2015.

Engaging Undergraduates in Methods of Communicating Global Climate Change

Hall, C.; Colgan, M. W.; Humphreys, R. R.

2010-12-01

Global Climate Change has become a politically contentious issue in large part because of the failure of scientists to effectively communicate this complex subject to the general public. In a Global Change class, offered within a science department and therefore focused primarily on the underlying science, we have incorporated a citizen science module into the course to raise awareness among future scientists to the importance of communicating information to a broad and diverse audience. The citizen science component of this course focuses on how the predicted climate changes will alter the ecologic and economic landscape of the southeastern region. Helping potential scientists to learn to effectively communicate with the general public is particularly poignant for this predominate southern student body. A Pew Research Center for the People and the Press study found that less than 50% of Southerners surveyed felt that global warming is a very serious problem and over 30% of Southerners did not believe that there was any credible evidence that the Earth is warming. This interdisciplinary and topical nature of the course attracts student from a variety of disciplines, which provides the class with a cross section of students not typically found in most geology classes. This mixture provides a diversity of skills and interest that leads to success of the Citizen Science component. This learning approach was adapted from an education module developed through the Earth System Science Education Alliance and a newly developed component to that program on citizen science. Student teams developed several citizen science-related public service announcements concerning projected global change effects on Charleston and the South Carolina area. The scenario concerned the development of an information campaign for the City of Charleston, culminating with the student presentations on their findings to City officials. Through this real-life process, the students developed new strategies that inform their own means of communicating science, whether to the general public, to peers, or to other scientists. This course with the citizen science component serves as a model for other programs. Incorporating a communication aspect into science courses that revolve around complex but socially important topics, such as global climate change, is necessary in building the confidence in our science students to communicate effectively, imaginatively, and memorably. In addition, the students gain a deeper understanding and appreciation of the necessity to communicate to public audiences and the value of outreach to the community.

We examined changes in adolescent self-reported parent-child communication using growth curve models conditional on family meal frequency over a 3.5-year period among a population of racially diverse, low-income adolescents from an urban environment (n = 4,750). Results indicated that although both family dinner frequency and adolescent perceptions of parent-child communication scores were characterized by negative linear growth over time (both p < .001), family dinner frequency was positively associated with adolescent perceptions of parent-child communication scores over time (p < .001). Study findings suggest that families with teenagers may enhance parent-child communication and ultimately promote healthy adolescent development by making family dinner a priority. In addition, the communication benefits of family dinner at the beginning of sixth grade may be protective through eighth grade. (c) 2010 APA, all rights reserved.

In Pursuit of Theoretical Ground in Behavior Change Support Systems: Analysis of Peer-to-Peer Communication in a Health-Related Online Community

PubMed Central

Cobb, Nathan; Cohen, Trevor

2016-01-01

Background Research studies involving health-related online communities have focused on examining network structure to understand mechanisms underlying behavior change. Content analysis of the messages exchanged in these communities has been limited to the “social support” perspective. However, existing behavior change theories suggest that message content plays a prominent role reflecting several sociocognitive factors that affect an individual’s efforts to make a lifestyle change. An understanding of these factors is imperative to identify and harness the mechanisms of behavior change in the Health 2.0 era. Objective The objective of this work is two-fold: (1) to harness digital communication data to capture essential meaning of communication and factors affecting a desired behavior change, and (2) to understand the applicability of existing behavior change theories to characterize peer-to-peer communication in online platforms. Methods In this paper, we describe grounded theory–based qualitative analysis of digital communication in QuitNet, an online community promoting smoking cessation. A database of 16,492 de-identified public messages from 1456 users from March 1-April 30, 2007, was used in our study. We analyzed 795 messages using grounded theory techniques to ensure thematic saturation. This analysis enabled identification of key concepts contained in the messages exchanged by QuitNet members, allowing us to understand the sociobehavioral intricacies underlying an individual’s efforts to cease smoking in a group setting. We further ascertained the relevance of the identified themes to theoretical constructs in existing behavior change theories (eg, Health Belief Model) and theoretically linked techniques of behavior change taxonomy. Results We identified 43 different concepts, which were then grouped under 12 themes based on analysis of 795 messages. Examples of concepts include “sleepiness,” “pledge,” “patch,” “spouse,” and “slip.” Examples of themes include “traditions,” “social support,” “obstacles,” “relapse,” and “cravings.” Results indicate that themes consisting of member-generated strategies such as “virtual bonfires” and “pledges” were related to the highest number of theoretical constructs from the existing behavior change theories. In addition, results indicate that the member-generated communication content supports sociocognitive constructs from more than one behavior change model, unlike the majority of the existing theory-driven interventions. Conclusions With the onset of mobile phones and ubiquitous Internet connectivity, online social network data reflect the intricacies of human health behavior as experienced by health consumers in real time. This study offers methodological insights for qualitative investigations that examine the various kinds of behavioral constructs prevalent in the messages exchanged among users of online communities. Theoretically, this study establishes the manifestation of existing behavior change theories in QuitNet-like online health communities. Pragmatically, it sets the stage for real-time, data-driven sociobehavioral interventions promoting healthy lifestyle modifications by allowing us to understand the emergent user needs to sustain a desired behavior change.

2016-08-01

To explore the effects of personalized prognostic information on physicians' intentions to communicate prognosis to cancer patients at the end of life, and to identify factors that moderate these effects. A factorial experiment was conducted in which 93 family medicine physicians were presented with a hypothetical vignette depicting an end-stage gastric cancer patient seeking prognostic information. Physicians' intentions to communicate prognosis were assessed before and after provision of personalized prognostic information, while emotional distress of the patient and ambiguity (imprecision) of the prognostic estimate were varied between subjects. General linear models were used to test the effects of personalized prognostic information, patient distress, and ambiguity on prognostic communication intentions, and potential moderating effects of 1) perceived patient distress, 2) perceived credibility of prognostic models, 3) physician numeracy (objective and subjective), and 4) physician aversion to risk and ambiguity. Provision of personalized prognostic information increased prognostic communication intentions (P < 0.001, η(2) = 0.38), although experimentally manipulated patient distress and prognostic ambiguity had no effects. Greater change in communication intentions was positively associated with higher perceived credibility of prognostic models (P = 0.007, η(2) = 0.10), higher objective numeracy (P = 0.01, η(2) = 0.09), female sex (P = 0.01, η(2) = 0.08), and lower perceived patient distress (P = 0.02, η(2) = 0.07). Intentions to communicate available personalized prognostic information were positively associated with higher perceived credibility of prognostic models (P = 0.02, η(2) = 0.09), higher subjective numeracy (P = 0.02, η(2) = 0.08), and lower ambiguity aversion (P = 0.06, η(2) = 0.04). Provision of personalized prognostic information increases physicians' prognostic communication intentions to a hypothetical end-stage cancer patient, and situational and physician characteristics moderate this effect. More research is needed to confirm these findings and elucidate the determinants of prognostic communication at the end of life. © The Author(s) 2016.

Pawl, Jean D; Anderson, Lori S

Consolidation of resources, programs, and even universities are measures that university systems consider for economic reasons. The transformation and restructuring of two diverse nursing programs utilized an organizational change tool to guide the consolidation efforts. Insights on how to use an organizational change model and lessons learned are shared for higher education units that may face consolidation. The ADKAR Change Management Model, one of many organizational change resources, was advantageous in consolidating two diverse nursing programs when two universities were mandated to become one. Change is inevitable yet when faced with transition and transformation, thoughtful and strong, committed leaders who portray open transparent communication are an absolute requirement for sustained change. To guide the process, the ADKAR Change Management Model is an insightful and worthwhile resource. Copyright © 2016 Elsevier Inc. All rights reserved.

Changing practice: implications of the World Report on Disability for responding to communication disability in under-served populations.

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

2013-02-01

The World Report on Disability provides a major challenge to the conceptualization and delivery of services for people with communication disabilities around the world. Many people, in both Majority and Minority World countries, receive limited or no support in relation to their communication disability. In this paper the prevalence of communication disability across the world (and the challenges to obtaining these data) are discussed, particularly in relation to disability more broadly. Populations that are under-served by speech-language pathology services in both Majority and Minority World countries are described. The paper describes organizational change theory and the potential it has, together with a biopsychosocial model of disability, to assist in understanding and influencing development of relevant services for people with communication disabilities (PWCD), particularly those who are under-served. Aspects of, and influences on, service delivery for PWCD are described. The need for novel ways of conceptualizing development of services, including population-based approaches, is highlighted. Finally, the challenges and opportunities for PWCD and for speech-language pathologists which arise from the nine recommendations of the World Report on Disability are considered and readers are encouraged to consider new and novel ways of developing equitable services for people with communication disabilities, in both majority and minority world settings.

Dynamics of Complex Systems Built as Coupled Physical, Communication and Decision Layers

PubMed Central

Kühnlenz, Florian; Nardelli, Pedro H. J.

2016-01-01

This paper proposes a simple model to capture the complexity of multilayer systems where their constituent layers affect, and are affected by, each other. The physical layer is a circuit composed by a power source and resistors in parallel. Every individual agent aims at maximizing its own delivered power by adding, removing or keeping the resistors it has; the delivered power is in turn a non-linear function that depends on the other agents’ behavior, its own internal state, its global state perception, the information received from its neighbors via the communication network and a randomized selfishness. We develop an agent-based simulation to analyze the effects of number of agents (system size), communication network topology, communication errors and the minimum power gain that triggers a behavioral change on the system dynamic. Our results show that a wave-like behavior at macro-level (caused by individual changes in the decision layer) can only emerge for a specific system size. The ratio between cooperators and defectors depends on the minimum gain assumed—lower minimal gains lead to less cooperation, and vice-versa. Different communication network topologies imply different levels of power utilization and fairness at the physical layer, and a certain level of error in the communication layer induces more cooperation.

Peyton, David J; Scicchitano, Michael

2017-12-01

Theory-based logic models are commonly developed as part of requirements for grant funding. As a tool to communicate complex social programs, theory based logic models are an effective visual communication. However, after initial development, theory based logic models are often abandoned and remain in their initial form despite changes in the program process. This paper examines the potential benefits of committing time and resources to revising the initial theory driven logic model and developing detailed logic models that describe key activities to accurately reflect the program and assist in effective program management. The authors use a funded special education teacher preparation program to exemplify the utility of drill down logic models. The paper concludes with lessons learned from the iterative revision process and suggests how the process can lead to more flexible and calibrated program management. Copyright © 2017 Elsevier Ltd.

Hilliard, Marisa; Sweenie, Rachel; Riekert, Kristin

2013-01-01

Transition from pediatric to adult care represents a high risk period for adolescents and emerging adults with diabetes. Fundamental differences between pediatric and adult care delivery models may contribute to increased risk for poor health outcomes. This review provides a brief overview of models of care in pediatric and adult settings and focuses on patient-provider communication content and quality as potential points of intervention to improve transition-related outcomes. This review also highlights disparities in transition and communication for adolescents and emerging adults from racial/ethnic minority groups and discusses recent changes in health care legislation that have significant implications for the transition process. Intervention opportunities include programs to enhance developmentally-appropriate patient-provider interactions and increased attention to promoting transition readiness skills. Improving patient-provider communication may hasten the development of vital self-advocacy skills needed in adult health care systems and, thus, help establish a lasting pattern of positive diabetes self-care.

Head and neck cancer (HNC) survivors may experience functional changes to their voice, speech and hearing following curative chemoradiotherapy. However, few studies have explored the impact of living with such changes from the perspective of the HNC survivor and their carer. The current study employed a person-centred approach to explore the lived experience of communication changes following chemoradiotherapy treatment for HNC from the perspective of survivors and carers. Participants included 14 survivors with non-glottic HNC and nine carers. All participants took part in in-depth interviews where they were encouraged to describe their experiences of living with and adjusting to communication changes following treatment. Interviews were analysed as a single data set. Four themes emerged including: (1) impairments in communication sub-systems; (2) the challenges of communicating in everyday life; (3) broad ranging effects of communication changes; and (4) adaptations as a result of communication changes. These data confirm that communication changes following chemoradiotherapy have potentially negative psychosocial impacts on both the HNC survivor and their carer. Clinicians should consider the impact of communication changes on the life of the HNC survivor and their carer and provide adequate and timely education and management to address the needs of this population.

To describe aspects facilitating or interfering in the communication process between nursing professionals and patients in critical state. Descriptive study conducted during the second semester of 2013, with the participation of 112 nurses who work in Intensive Care Units of Bogotá (Colombia). To gather the information, the researchers designed a survey. A total of 91.6% of the nursing professionals considers communication important with patients and their families; 75.9% seeks to provide, during the care interventions, physical care and communicate per shift from two to four times with the patient and from one to two times with the family; 50% states feeling afraid to communicate; only 53.7% integrate their emotions in the patient's physical care. Regarding the elements of communication developed during their graduate formation, 42.8% received tools of therapeutic communication during their undergraduate studies and only 33.0% during graduate studies. It is worth to indicate that 80.36% of the Intensive Care Units, where the nursing professionals work, privilege interventions aimed at satisfying physiological needs. The communication process between nurses and patients in critical state is limited by restrictive institutional policies and by the nurse' scarce academic formation. The need exists to start a process of change in relation to models of professional practice deeply rooted in physical care of critical patients to establish models that, during physical care, are centered on communication and the patient-family-professional relationship.

Communicating uncertainty in circulation aspects of climate change

NASA Astrophysics Data System (ADS)

Shepherd, Ted

2017-04-01

The usual way of representing uncertainty in climate change is to define a likelihood range of possible futures, conditioned on a particular pathway of greenhouse gas concentrations (RCPs). Typically these likelihood ranges are derived from multi-model ensembles. However, there is no obvious basis for treating such ensembles as probability distributions. Moreover, for aspects of climate related to atmospheric circulation, such an approach generally leads to large uncertainty and low confidence in projections. Yet this does not mean that the associated climate risks are small. We therefore need to develop suitable ways of communicating climate risk whilst acknowledging the uncertainties. This talk will outline an approach based on conditioning the purely thermodynamic aspects of climate change, concerning which there is comparatively high confidence, on circulation-related aspects, and treating the latter through non-probabilistic storylines.

A randomized prevention trial contrasted families who took part in the Strong African American Families Program (SAAF), a preventive intervention for rural African American mothers and their 11-year-olds, with control families. SAAF is based on a contextual model positing that regulated, communicative parenting causes changes in factors protecting youths from early alcohol use and sexual activity. Parenting variables included involvement-vigilance, racial socialization, communication about sex, and clear expectations for alcohol use. Youth protective factors included negative attitudes about early alcohol use and sexual activity, negative images of drinking youths, resistance efficacy, a goal-directed future orientation, and acceptance of parental influence. Intervention-induced changes in parenting mediated the effect of intervention group influences on changes in protective factors over a 7-month period.

MyPlate, the icon and multimodal communication plan developed for the 2010 Dietary Guidelines for Americans (DGA), provides an opportunity to consider new approaches to evaluating the effectiveness of communication initiatives. A review of indicators used in assessments for previous DGA communication initiatives finds gaps in accounting for important intermediate and long-term outcomes. This evaluation framework for the MyPlate Communications Initiative builds on well-known and underused models and theories to propose a wide breadth of observations, outputs, and outcomes that can contribute to a fuller assessment of effectiveness. Two areas are suggested to focus evaluation efforts in order to advance understanding of the effectiveness of the MyPlate Communications Initiative: understanding the extent to which messages and products from the initiative are associated with positive changes in social norms toward the desired behaviors, and strategies to increase the effectiveness of communications about DGA in vulnerable populations.

Objective This study sought to identify possible associations between maternal coping and depression and subsequent mother–child communication about cancer following the child’s diagnosis. Method Mothers (N = 100) reported on coping and depressive symptoms shortly after the child’s diagnosis (M = 1.9 months). Subsequently, we observed children (age 5–17 years; M = 10.2 years; 48% female; 81% White) and mothers discussing cancer and coded maternal communication. Results Higher primary and secondary control coping, and lower depressive symptoms, were generally correlated with more positive, and less harsh and withdrawn communication. In regression models, higher primary control coping (i.e., coping efforts to change the stressor or one’s emotional reaction to the stressor) independently predicted less withdrawn communication, and depressive symptoms mediated relations between coping and harsh communication. Conclusions Maternal primary control coping and depressive symptoms predict mothers’ subsequent harsh and withdrawn communication about cancer.

Deficits in attention, communication, imitation, and play skills reduce opportunities for children with autism to learn from natural interactive experiences that occur throughout the day. These developmental delays are already present by the time these children reach the toddler period. The current study provided a brief 12 week, 1 hour per week, individualized parent-child education program to eight toddlers newly diagnosed with autism. Parents learned to implement naturalistic therapeutic techniques from the Early Start Denver Model, which fuses developmental- and relationship-based approaches with Applied Behavior Analysis into their ongoing family routines and parent-child play activities. Results demonstrated that parents acquired the strategies by the fifth to sixth hour and children demonstrated sustained change and growth in social communication behaviors. Findings are discussed in relation to providing parents with the necessary tools to engage, communicate with, and teach their young children with autism beginning immediately after the diagnosis.

Camouflage, communication and thermoregulation: lessons from colour changing organisms.

Organisms capable of rapid physiological colour change have become model taxa in the study of camouflage because they are able to respond dynamically to the changes in their visual environment. Here, we briefly review the ways in which studies of colour changing organisms have contributed to our understanding of camouflage and highlight some unique opportunities they present. First, from a proximate perspective, comparison of visual cues triggering camouflage responses and the visual perception mechanisms involved can provide insight into general visual processing rules. Second, colour changing animals can potentially tailor their camouflage response not only to different backgrounds but also to multiple predators with different visual capabilities. We present new data showing that such facultative crypsis may be widespread in at least one group, the dwarf chameleons. From an ultimate perspective, we argue that colour changing organisms are ideally suited to experimental and comparative studies of evolutionary interactions between the three primary functions of animal colour patterns: camouflage; communication; and thermoregulation.

Profound changes in the way dental practices manage data, patient records, and communication are beginning to unfold. Sooner than most of us can imagine, secured patient medical and dental records will reside on the Internet. Additionally, communication between health care providers and patients will become virtually 100% electronic. As the Application Service Provider (ASP) dental models mature, practices will transition from paper to "paperless" to "web-based" management and clinical systems. This article examines and explains these future frontiers.

Brief Report: Relationships Among Spousal Communication, Self-Efficacy, and Motivation Among Expectant Latino Fathers Who Smoke

Objective Cigarette smoking is a prevalent problem among Latinos, yet little is known about what factors motivate them to quit smoking or make them feel more confident that they can. Given cultural emphases on familial bonds among Latinos (e.g., familismo), it is possible that communication processes among Latino spouses play an important role. The present study tested a mechanistic model in which perceived spousal constructive communication patterns predicted changes in level of motivation for smoking cessation through changes in self-efficacy among Latino expectant fathers. Methods Latino males (n = 173) and their pregnant partners participated in a couple-based intervention targeting males’ smoking. Couples completed self-report measures of constructive communication, self-efficacy (male partners only), and motivation to quit (male partners only) at four time points throughout the intervention. Results Higher levels of perceived constructive communication among Latino male partners predicted subsequent increases in male’s partners’ self-efficacy and, to a lesser degree, motivation to quit smoking; however, self-efficacy did not mediate associations between constructive communication and motivation to quit smoking. Furthermore, positive relationships with communication were only significant at measurements taken after completion of the intervention. Female partners’ level of perceived constructive communication did not predict male partners’ outcomes. Conclusion These results provide preliminary evidence to support the utility of couple-based interventions for Latino men who smoke. Findings also suggest that perceptions of communication processes among Latino partners (particularly male partners) may be an important target for interventions aimed increasing desire and perceived ability to quit smoking among Latino men.

Although abortion became legal in India in 1971, many women are unaware of the law. Behavior change communication interventions may be an effective way to promote awareness of the law and change knowledge of and perceptions about abortion, particularly in settings in which abortion is stigmatized. To evaluate the effectiveness of a behavior change communication intervention to improve women's knowledge about India's abortion law and their perceptions about abortion, a quasi-experimental study was conducted in intervention and comparison districts in Bihar and Jharkhand. Household surveys were administered at baseline in 2008 and at follow-up in 2010 to independent, randomly selected cross-sectional samples of rural married women aged 15-49. Logistic regression difference-in-differences models were used to assess program effectiveness. Analysis demonstrated program effectiveness in improving awareness and perceptions about abortion. The changes in the odds of knowing that abortion is legal and where to obtain safe abortion services were larger between baseline and follow-up in the intervention districts than the changes in odds observed in the comparison districts (odds ratios, 16.1 and 1.9, respectively). Similarly, the increase in women's perception of greater social support for abortion within their families and the increase in perceived self-efficacy with respect to family planning and abortion between baseline and follow-up was greater in the intervention districts than in the comparison districts (coefficients, 0.17 and 0.18, respectively). Behavior change communication interventions can be effective in improving knowledge of and perceptions about abortion in settings in which lack of accurate knowledge hinders women's access to safe abortion services. Multiple approaches should be used when attempting to improve knowledge and perceptions about stigmatized health issues such as abortion.

This article describes how trust among team members and in the technology supporting them was eroded during implementation of an electronic health record (EHR) in an adult outpatient oncology practice at a comprehensive cancer center. Delays in care of a 38-year-old woman with high-risk breast cancer occurred because of ineffective team communication and are illustrated in a case study. The case explores how the patient's trust and mutual trust between team members were disrupted because of inaccurate assumptions about the functionality of the EHR's communication tool, resultant miscommunications between team members and the patient, and the eventual recognition that care was not being effectively coordinated, as it had been previously. Despite a well-established, team-based culture and significant preparation for the EHR implementation, the challenges that occurred point to underlying human and system failures from which other organizations going through a similar process may learn. Through an analysis and evaluation of events that transpired before and during the EHR rollout, suggested interventions for preventing this experience are offered, which include: a thorough crosswalk between old and new communication mechanisms before implementation; understanding and mitigation of gaps in the communication tool's functionality; more robust training for staff, clinicians, and patients; greater consideration given to the pace of change expected of individuals; and development of models of collaboration between EHR users and vendors in developing products that support high-quality, team-based care in the oncology setting. These interventions are transferable to any organizational or system change that threatens mutual trust and effective communication.

Entertainment-education (EE) is a popular vehicle for behavior change communication (BCC) in many areas of public health, especially in the developing world where soap operas and other serial drama formats play a central role in encouraging people to avoid risky behavior. Yet BCC/EE developers have been largely unable to integrate behavioral theory and research systematically into storylines and scripts, depending instead on external, technical oversight of what should be an essentially local, creative process. This article describes how the Modeling and Reinforcement to Combat HIV/AIDS project at the Centers for Disease Control and Prevention has developed a set of tools through which creative writers can exercise greater control over the behavioral content of their stories. The Pathways to Change tools both guide scriptwriters as they write BCC/EE storylines and help project managers monitor BCC/EE products for theoretical fidelity and sensitivity to research.

Existing theoretical work in decision making and behavior change has focused on how individuals arrive at decisions or form intentions. Less attention has been given to theorizing the requirements that might be necessary for individuals to work collaboratively to address difficult decisions, consider new alternatives, or change behaviors. The goal of this work was to develop, as a forerunner to a middle range theory, a conceptual model that considers the process of supporting patients to consider alternative health care options, in collaboration with clinicians, and others. Theory building among researchers with experience and expertise in clinician-patient communication, using an iterative cycle of discussions. We developed a model composed of five inter-related propositions that serve as a foundation for clinical communication processes that honor the ethical principles of respecting individual agency, autonomy, and an empathic approach to practice. We named the model 'collaborative deliberation.' The propositions describe: (1) constructive interpersonal engagement, (2) recognition of alternative actions, (3) comparative learning, (4) preference construction and elicitation, and (5) preference integration. We believe the model underpins multiple suggested approaches to clinical practice that take the form of patient centered care, motivational interviewing, goal setting, action planning, and shared decision making.

Centering Pregnancy, an innovative group model of prenatal care, shows promise to reduce persistent adverse maternal-infant outcomes and contain costs. Because this innovation requires systemwide change, clinics reported needing support enrolling women into groups and obtaining organizational buy-in. This study used the 3-step social marketing communication strategy to help clinic staff identify key customers and customer-specific barriers to adopting or supporting Centering Pregnancy. They developed targeted information to reduce barriers and built skills in communicating with different customers through role-playing. Findings provide practical information for others to use this communication strategy to improve implementation of Centering Pregnancy.

As indicated early by Charles Darwin, languages behave and change very much like living species. They display high diversity, differentiate in space and time, emerge and disappear. A large body of literature has explored the role of information exchanges and communicative constraints in groups of agents under selective scenarios. These models have been very helpful in providing a rationale on how complex forms of communication emerge under evolutionary pressures. However, other patterns of large-scale organization can be described using mathematical methods ignoring communicative traits. These approaches consider shorter time scales and have been developed by exploiting both theoretical ecology and statistical physics methods. The models are reviewed here and include extinction, invasion, origination, spatial organization, coexistence and diversity as key concepts and are very simple in their defining rules. Such simplicity is used in order to catch the most fundamental laws of organization and those universal ingredients responsible for qualitative traits. The similarities between observed and predicted patterns indicate that an ecological theory of language is emerging, supporting (on a quantitative basis) its ecological nature, although key differences are also present. Here, we critically review some recent advances and outline their implications and limitations as well as highlight problems for future research.

Background Communication and marketing are rapidly becoming recognized as core functions, or core competencies, in the field of public health. Although these disciplines have fostered considerable academic inquiry, a coherent sense of precisely how these disciplines can inform the practice of public health has been slower to emerge. Discussion In this article we propose a framework – based on contemporary ecological models of health – to explain how communication and marketing can be used to advance public health objectives. The framework identifies the attributes of people (as individuals, as social networks, and as communities or populations) and places that influence health behaviors and health. Communication, i.e., the provision of information, can be used in a variety of ways to foster beneficial change among both people (e.g., activating social support for smoking cessation among peers) and places (e.g., convincing city officials to ban smoking in public venues). Similarly, marketing, i.e., the development, distribution and promotion of products and services, can be used to foster beneficial change among both people (e.g., by making nicotine replacement therapy more accessible and affordable) and places (e.g., by providing city officials with model anti-tobacco legislation that can be adapted for use in their jurisdiction). Summary Public health agencies that use their communication and marketing resources effectively to support people in making healthful decisions and to foster health-promoting environments have considerable opportunity to advance the public's health, even within the constraints of their current resource base.

The complexity of organizational change: describing communication during organizational turbulence.

Salem, Philip

2013-01-01

Organizational researchers and practitioners have been interested in organizational change for some time. Historically, they have directed most of their efforts at improving the efficiency of planned top-down change. These efforts were strategic attempts at altering parameters leading to transformational change. Most efforts failed to meet their intended purposes. Transformational organizational change has not been likely. The legitimate systems have been robust. There has been little systematic investigation of the communication occurring during these efforts. The purpose of this essay is to describe results of a mixed methods research project answering two research questions. (a) How do organizational members communicate during a time of turbulence? (b) What features of this communication suggest the potential for or resistance to transformative change? Comparing the results at the beginning of the period to other periods, gives insight into how social actors communicate and enact the organization during a threshold period where transformational change was possible. Results reveal identifiable patterns of communication as communication strategies, parameters, or basins of attraction. The overall pattern explains how micro communication patterns intersect and how the accumulation of these patterns may resist or accomplish change at a macro level.

2010-03-01

Japan's 2008 health policy focuses more than ever on health education for behaviour change and outcome measures for physical health status. This is at odds with contemporary health promotion and health education, which frame health as a resource for everyday life and indicate that the evaluation of interventions should measure broader aspects of health rather than just physical aspects. The application of a combination of different health communication models and theories allows for a customized approach, depending on the types of change that are being sought, and can lead to increased relevance as well as a better fit when it comes to evaluating the achievement of broad health promotion goals. This article explores the application of the Outcome Model for Health Promotion to a two-year health education intervention in Kushima, Japan. This model measures program effectiveness from four aspects: physical health outcomes; intermediate health outcomes; health promotion outcomes; and health promotion actions. A quantitative and qualitative longitudinal, mixed model study design and methods were used for the analysis. Data was taken from health exams, structured interviews, and participant observations collected from 67 participants at four times over two years. This intervention relied primarily on health education and communication to achieve mental and social health outcomes more significantly and faster than physical health outcomes. The importance of moving outcome measurement beyond direct health achievements is discussed in light of the relationships between physical, mental, and social health and its determinants, and our results.

Objective Great Taste, Less Waste (GTLW), a communications campaign, capitalized on the synergy between healthy eating and eco-friendly behaviors to motivate children to bring more fruits and vegetables and fewer sugar-sweetened beverages (SSBs) to school. Methods A cluster-randomized trial in Eastern Massachusetts elementary schools in 2011–2012 tested the hypothesis that GTLW would improve the quality of foods from home more than a nutrition-only campaign – Foods 2 Choose (F2C) – or control. Lunch and snack items from home were measured at baseline and 7 months later using digital photography. Mixed linear models compared change in mean servings of fruits, vegetables, and SSBs among groups, and change in mean prevalence of packaging type. Change in prevalence of food items of interest was compared among groups using generalized linear models. Results 582 third and fourth graders from 82 classrooms in 12 schools participated. At follow-up, no significant differences were observed between groups in change in mean servings or change in prevalence of items of interest. No packaging differences were observed. Conclusion GTLW was well-received but no significant changes were observed in the quality of food brought to school. Whether classrooms are an effective environment for change remains to be explored.

Communicating for policy change.

PubMed

2007-11-01

A decade ago few foundations viewed communications as an important tool for achieving strategic goals, and only a handful specifically relied on communications activities to influence policy change. This history reflects, in large part, the nascent role of communications activities in philanthropy. More focused questions regarding the fit between mission and policy reform objectives, however, have also dampened and continue to moderate support for communications as an instrument for policy change. Funders wishing to utilize communications to facilitate policy change actually have a great deal of latitude to do so, but, until recently, conservative interpretations of lobbying restrictions have made many foundations wary of policy advocacy. Ambitious communications efforts that might appear too vocal or politically pointed were especially uncommon.

Characterizing Nanoscale Transient Communication.

PubMed

Chen, Yifan; Anwar, Putri Santi; Huang, Limin; Asvial, Muhamad

2016-04-01

We consider the novel paradigm of nanoscale transient communication (NTC), where certain components of the small-scale communication link are physically transient. As such, the transmitter and the receiver may change their properties over a prescribed lifespan due to their time-varying structures. The NTC systems may find important applications in the biomedical, environmental, and military fields, where system degradability allows for benign integration into life and environment. In this paper, we analyze the NTC systems from the channel-modeling and capacity-analysis perspectives and focus on the stochastically meaningful slow transience scenario, where the coherence time of degeneration Td is much longer than the coding delay Tc. We first develop novel and parsimonious models to characterize the NTC channels, where three types of physical layers are considered: electromagnetism-based terahertz (THz) communication, diffusion-based molecular communication (DMC), and nanobots-assisted touchable communication (TouchCom). We then revisit the classical performance measure of ϵ-outage channel capacity and take a fresh look at its formulations in the NTC context. Next, we present the notion of capacity degeneration profile (CDP), which describes the reduction of channel capacity with respect to the degeneration time. Finally, we provide numerical examples to demonstrate the features of CDP. To the best of our knowledge, the current work represents a first attempt to systematically evaluate the quality of nanoscale communication systems deteriorating with time.

Is sociality required for the evolution of communicative complexity? Evidence weighed against alternative hypotheses in diverse taxonomic groups

PubMed Central

Ord, Terry J.; Garcia-Porta, Joan

2012-01-01

Complex social communication is expected to evolve whenever animals engage in many and varied social interactions; that is, sociality should promote communicative complexity. Yet, informal comparisons among phylogenetically independent taxonomic groups seem to cast doubt on the putative role of social factors in the evolution of complex communication. Here, we provide a formal test of the sociality hypothesis alongside alternative explanations for the evolution of communicative complexity. We compiled data documenting variations in signal complexity among closely related species for several case study groups—ants, frogs, lizards and birds—and used new phylogenetic methods to investigate the factors underlying communication evolution. Social factors were only implicated in the evolution of complex visual signals in lizards. Ecology, and to some degree allometry, were most likely explanations for complexity in the vocal signals of frogs (ecology) and birds (ecology and allometry). There was some evidence for adaptive evolution in the pheromone complexity of ants, although no compelling selection pressure was identified. For most taxa, phylogenetic null models were consistently ranked above adaptive models and, for some taxa, signal complexity seems to have accumulated in species via incremental or random changes over long periods of evolutionary time. Becoming social presumably leads to the origin of social communication in animals, but its subsequent influence on the trajectory of signal evolution has been neither clear-cut nor general among taxonomic groups.

Changes in Marital and Partner Relationships in the Aftermath of Hurricane Katrina: An Analysis With Low-Income Women.

Little is known about the impact of natural disasters on marital and partner relationships. In this study, the authors aimed to fill this gap by investigating the changes in such relationships in a sample of 40 low-income, mostly African American women who survived Hurricane Katrina. Through in-depth interviews, participants described how the hurricane affected their intimate relationships. The authors found that, although many participants reported negative changes in their relationships, others reported that their relationships grew stronger, often despite initial strain. As a framework for understanding the processes underlying participants' negative and positive outcomes, the authors drew on the family stress model. Consistent with the model, participants reported that the hurricane led to external stressors, including unemployment and prolonged separations, and that these stressors, in turn, undermined both individual functioning and relational processes (e.g., communication and support). Conversely, participants reporting positive changes experienced new employment opportunities, a greater sense of perspective, and high levels of effective communication and support in their relationships. Based on the findings, policies that reduce the economic strain of low-income families in the aftermath of disasters and empirically supported, culturally sensitive, clinical interventions for individuals and couples are recommended.

Information and discussion of sexual changes with a health professional is a high priority for many cancer patients in order to assist with sexual changes and ensure that sexual intimacy does not cease post-cancer. The PLISSIT model is widely recommended as a framework for providing sexual information and support, allowing for the discussion of sexual changes at various levels of increasing intensity. The aim of the present study is to evaluate the early stages of the PLISSIT model by examining the relative efficacy of written information provision about cancer related sexual changes, and information provision accompanied by a single session of counselling, for people with cancer and their partners, across a range of cancer types. Eighty-eight people with cancer and 53 partners across a range of sexual and non-sexual cancers, took part in a randomised trial which adopted mixed method analysis to examine changes in psychological wellbeing, quality of life, relationship satisfaction and communication, and sexual functioning, following written information provision about cancer related sexual changes (self-help condition; SH), or written information accompanied by a single session of counselling (health professional condition; HP). Ratings of the usefulness and efficacy of the SH and HP interventions, collected through analysis of Likert scales, open ended survey items and interviews, indicated that both conditions were found to be useful and efficacious by the majority of participants, serving to increase awareness of sexuality, improve couple communication about sex, and help in the management of sexual changes, through the exploration of non-coital sexual practices. In contrast, the quantitative analysis of standardized instruments found no significant improvements in psychological wellbeing, quality of life, relationship satisfaction and communication, or sexual functioning. There were significant reductions in self-silencing in the HP condition, and a trend towards increases in sexual satisfaction across both conditions. These results offer support for the early stages of the PLISSIT model, in terms of normalization and increased awareness of sexual changes after cancer, increased couple communication about sexual changes, and legitimation of exploration of a range of non-coital sexual practices and intimacy. However, more complex and intensive interventions are needed to address sexual functioning and psychological wellbeing. The findings provide support for the proposition that providing permission to discuss sexuality should be the core feature underpinning all stages of interventions designed to provide sexuality information and support for people with cancer and their partners, and also demonstrate the potential importance of limited information and specific suggestions.

Change management in health care.

PubMed

Campbell, Robert James

2008-01-01

This article introduces health care managers to the theories and philosophies of John Kotter and William Bridges, 2 leaders in the evolving field of change management. For Kotter, change has both an emotional and situational component, and methods for managing each are expressed in his 8-step model (developing urgency, building a guiding team, creating a vision, communicating for buy-in, enabling action, creating short-term wins, don't let up, and making it stick). Bridges deals with change at a more granular, individual level, suggesting that change within a health care organization means that individuals must transition from one identity to a new identity when they are involved in a process of change. According to Bridges, transitions occur in 3 steps: endings, the neutral zone, and beginnings. The major steps and important concepts within the models of each are addressed, and examples are provided to demonstrate how health care managers can actualize the models within their health care organizations.

AIDS communications through social networks: catalyst for behaviour changes in Uganda.

PubMed

Low-Beer, Daniel; Stoneburner, Rand L

2004-05-01

To investigate distinctive communications through social networks which may be associated with population behaviour changes and HIV prevalence declines in Uganda compared to other countries. We undertook a comparative analysis of demographic and HIV behavioural data collected in Demographic and Health Surveys (DHS III) in Uganda, Kenya, Tanzania, Malawi, Zambia and Zimbabwe as well as Knowledge, Attitudes and Behaviours (KABP) surveys in Uganda in 1989 and 1995. AIDS behaviours, social communications and channels for communication about AIDS and people with AIDS were analysed by age, sex and country. Modelling was developed to investigate at what stage of the epidemic a majority of people will know someone with AIDS, given differing communication patterns through social networks. Finally AIDS reporting and Voluntary Counselling and Testing (VCT) trends were analysed to assess if the impact of social communications worked through clinical services and interventions or more directly at the population level in community contexts. Uganda showed unique patterns of communications through social networks including a shift from mass and institutional to personal channels for communicating about AIDS, 1989-1995. This was associated with higher levels of knowing someone with AIDS through social networks and, in turn, positive risk ratios for behaviour change including reducing casual sex and condom use. Youth had distinctively high levels of knowing someone with AIDS in Uganda, suggesting widespread community communication across age groups. Patterns of disclosure, AIDS diagnosis and reporting were influential on social communications about AIDS. Over 90%, 45% or under 20% of people know someone with AIDS at peak HIV incidence and high AIDS mortality, depending on whether communications through social networks are extensive or restricted. There are distinctive patterns for communicating through social networks about AIDS and people with AIDS in Uganda. They appear to work directly at population level rather than in response to clinical interventions and testing and may be important in the uptake of the latter services. This communication response provides an important basis for HIV prevention if it is to be scaled to the population level. Vertical prevention (and even treatment) interventions need to engage more closely with local, horizontal communication and behavioural responses to AIDS. Communication programmes have to take root at the level of social networks working though local networks of meetings, chiefs, churches and health personnel as well as the media. Mobilising basic social communications may be a necessary resource (as much as services and finance) to scale HIV prevention and treatment to the population level.

1998-01-01

In many settings, primary care physicians have begun to delegate inpatient care to hospitalists, but the impact of this change on patients' hospital experience is unknown. To determine the effect on physician-patient communication of having the regular outpatient physician (continuity physician) continue involvement in hospital care, we surveyed 1,059 consecutive patients hospitalized with chest pain. Patients whose continuity physicians remained involved in their hospital care were less likely to report communication problems regarding tests (20% vs 31%, p = .03), activity after discharge (42% vs 51%, p = .02), and health habits (31% vs 38%, p = .07). In a setting without a designated hospitalist system, communication problems were less frequent among patients whose continuity physicians were involved in their hospital care. New models of inpatient care delivery can maintain patient satisfaction but to do so must focus attention on improving physician-patient communication. PMID:9844081

This article discusses the value of the MessageWorks tool to health communicators and to the field of social marketing by (1) describing the scientific evidence supporting use of MessageWorks to improve health communication practice and (2) summarizing how to use MessageWorks and interpret the results it produces.

A Theory-Based Socioecological Model of Communication and Behavior for the Containment of the Ebola Epidemic in Liberia.

PubMed

Figueroa, Maria Elena

2017-01-01

The Ebola virus disease that emerged in the West African countries of Liberia, Sierra Leone, and Guinea in 2014 created an unprecedented public health emergency that caught national and international organizations off guard. Despite available guidelines to respond to public health emergencies, coordinated action to control the disease only came almost 6 months after what is now considered the first human contact with the virus. Theory-based frameworks, like the ideation model and the pathways framework, are important tools for guiding research and the design of communication activities and strategies to effectively impact on the more likely determinants of the intended behavior. By using theory, these frameworks increase the chances that localized research and communication interventions can effectively change desired behaviors and their behavioral determinants. In an outbreak situation such frameworks are all the more important, when time is of the essence and lives are on the line.

Teaching communication and supporting autonomy with a team-based operative simulator.

Changing residency structure emphasizes the need for formal instruction on team leadership and intraoperative teaching skills. A high fidelity, multi-learner surgical simulation may offer opportunities for senior learners (SLs) to learn these skills while teaching technical skills to junior learners (JLs). We designed and optimized a low-cost inguinal hernia model that paired JLs and SLs as an operative team. This was tested in 3 pilot simulations. Participants' feedback was analyzed using qualitative methods. JL feedback to SLs included the themes "guiding and instructing" and "allowing autonomy." Senior Learner feedback to JLs focused on "mechanics," "knowledge," and "perspective/flow." Both groups focused on "communication" and "professionalism." A multi-learner simulation can successfully meet the technical learning needs of JLs and the teaching and communication learning needs of SLs. This model of resident-driven simulation may illustrate future opportunities for operative simulation. Copyright © 2016 Elsevier Inc. All rights reserved.

Empirical support regarding effective interventions for individuals with autism spectrum disorder (ASD) within a postsecondary community is limited. Video modeling, an empirically supported intervention for children and adolescents with ASD, may prove effective in addressing the needs of individuals with ASD in higher education. This study evaluated the effects of video modeling without additional treatment components to improve social-communicative skills, specifically, eye contact, facial expression, and conversational turntaking in college students with ASD. This study utilized a multiple baseline single-case design across behaviors for two post-secondary students with ASD to evaluate the effects of the video modeling intervention. Large effect sizes and statistically significant change across all targeted skills for one participant and eye contact and turntaking for the other participant were obtained. The use of video modeling without additional intervention may increase the social skills of post-secondary students with ASD. Implications for future research are discussed.

Diffusion Dynamics of Energy Saving Practices in Large Heterogeneous Online Networks

Online social networks are today’s fastest growing communications channel and a popular source of information for many, so understanding their contribution to building awareness and shaping public perceptions of climate change is of utmost importance. Today’s online social networks are composed of complex combinations of entities and communication channels and it is not clear which communicators are the most influential, what the patterns of communication flow are, or even whether the widely accepted two-step flow of communication model applies in this new arena. This study examines the diffusion of energy saving practices in a large online social network across organizations, opinion leaders, and the public by tracking 108,771 communications on energy saving practices among 1,084 communicators, then analyzing the flow of information and influence over a 28 day period. Our findings suggest that diffusion networks of messages advocating energy saving practices are predominantly led by the activities of dedicated organizations but their attempts do not result in substantial public awareness, as most of these communications are effectively trapped in organizational loops in which messages are simply shared between organizations. Despite their comparably significant influential values, opinion leaders played a weak role in diffusing energy saving practices to a wider audience. Thus, the two-step flow of communication model does not appear to describe the sharing of energy conservation practices in large online heterogeneous networks. These results shed new light on the underlying mechanisms driving the diffusion of important societal issues such as energy efficiency, particularly in the context of large online social media outlets.

2016-09-01

Knowing one's serostatus is critical in the HIV prevention, care and treatment continuum. This study examines the impact of communication programs on HIV testing in South Africa. Data came from 2204 young men and women aged 16-24 who reported to be sexually active in a population based survey. Structural equation modeling was used to test the directions and causal pathways between communication program exposure, HIV testing discussion, and having a test in the last 12 months. Bivariate and multivariate probit regressions provided evidence of exogeneity of communication exposure and the two HIV-related outcomes. One in three sampled individuals had been tested in the last 12 months. Communication program exposure only had an indirect effect on getting tested by encouraging young people to talk about testing. The study suggests that communication programs may create an environment that supports open HIV-related discussions and may have a long-term impact on behavior change.

Objective To examine changes in parent–child communication patterns and their relation to glycemic control and treatment adherence using observational data in a 3-year prospective multisite study of youth with type 1 diabetes aged 9–11 years at baseline and their families (n = 217). Methods Adolescents and caregivers participated in a diabetes problem-solving discussion. Families were rated on negative and positive communication and interactions using the Interaction Behavior Code. Results Maternal and paternal negative communication decreased over time, whereas adolescent and maternal positive communication and positive reciprocity increased. Baseline preadolescent youth and maternal positive communication predicted adherence 3 years later. Changes in family communication did not predict changes in glycemic control or adherence. Conclusions During the transition to adolescence, family communication changed in unexpected and positive ways. Additionally, the relationship of baseline family communication to subsequent adherence suggests the need to assess family communication concerning diabetes-related management during preadolescence.

Entropy of dynamical social networks

Dynamical social networks are evolving rapidly and are highly adaptive. Characterizing the information encoded in social networks is essential to gain insight into the structure, evolution, adaptability and dynamics. Recently entropy measures have been used to quantify the information in email correspondence, static networks and mobility patterns. Nevertheless, we still lack methods to quantify the information encoded in time-varying dynamical social networks. In this talk we present a model to quantify the entropy of dynamical social networks and use this model to analyze the data of phone-call communication. We show evidence that the entropy of the phone-call interaction network changes according to circadian rhythms. Moreover we show that social networks are extremely adaptive and are modified by the use of technologies such as mobile phone communication. Indeed the statistics of duration of phone-call is described by a Weibull distribution and is significantly different from the distribution of duration of face-to-face interactions in a conference. Finally we investigate how much the entropy of dynamical social networks changes in realistic models of phone-call or face-to face interactions characterizing in this way different type human social behavior.

Experiences in Conducting Participatory Communication Research for HIV Prevention Globally: Translating Critical Dialog into Action through Action Media.

PubMed

Parker, Warren Martin; Becker-Benton, Antje

2016-01-01

Developing communication to support health and well-being of vulnerable communities requires a multifaceted understanding of local perspectives of contextual challenges and potentials for change. While participatory research enhances understanding, robust methodologies are necessary to translate emerging concepts into viable communication approaches. Communicators and change agents need to clarify pathways for change, barriers and enablers for change, as well as the role, orientation, and content of communication to support change. While various approaches to participatory action research with vulnerable communities have been developed, there is a dearth of methodologies that address the formulation of communication concepts that can be applied at scale. The Action Media methodology has been refined over a period of two decades, being applied to addressing HIV, related aspects such as gender-based violence, as well as broader issues, such as maternal and child health, sanitation, and malaria in Africa, The Caribbean, and Asia. The approach employs a sequence of interactive sessions involving communicator researchers and participants from one or more communities that face social or health challenges. Sessions focus on understanding audiences through their engagement with these challenges and leading to shaping of relevant communication concepts that can be linked to mobilization for change. The Action Media methodology contributes to processes of shared learning linked to addressing social and health challenges. This includes determining priorities, identifying barriers and facilitators for change, understanding processes of mobilizing knowledge in relation to context, determining appropriate communication approaches, and integrating indigenous language and cultural perspectives into communication concepts. Emerging communication strategies include support to systematic action and long-term mobilization. Communication to address public health concerns is typically developed through expert-led didactic approaches that, at best, engage audiences at the end of the development cycle through pretesting of communication concepts. Action Media provides an alternative approach that can be utilized to inform communication by integrating community perspectives at the outset. Notwithstanding the focused engagement with small group representative of health-vulnerable subpopulations, Action Media findings have informed large-scale communication interventions. The approach is directly linked to enabling ownership, critical thinking, and mobilization of knowledge for change.

In this paper we develop an order driver market model with heterogeneous traders that imitate each other on different network structures. We assess how imitations among otherway noise traders, can give rise to well known stylized facts such as fat tails and volatility clustering. We examine the impact of communication and imitation on the statistical properties of prices and order flows when changing the networks' structure, and show that the imitation of a given, fixed agent, called “guru", can generate clustering of volatility in the model. We also find a positive correlation between volatility and bid-ask spread, and between fat-tailed fluctuations in asset prices and gap sizes in the order book. in here

Background This study aimed to compare the effectiveness of a high-intensity model (HIM) and a low-intensity model (LIM) of behaviour change communication interventions in Bihar and Jharkhand states of India designed to improve women's knowledge and usage of safe abortion services, as well as the dose effect of intervention exposure. Methods We conducted two cross-sectional household surveys among married women aged 15–49 years in intervention and comparison districts. Difference-in-difference models were used to assess the efficacy of the intervention, adjusting for sociodemographic characteristics. Results Although both intervention types improved abortion knowledge, the HIM intervention was more effective in improving comprehensive knowledge about abortion. In particular, there were improvements in knowledge on legality of abortion (AOR=2.2; 95% CI 1.6 to 2.9) and nearby sources of safe abortion care (AOR=1.7; 95% CI 1.2 to 1.3). Conclusions Higher level of exposure to abortion-related messages was related to more accurate knowledge about abortion within both intervention groups. Evidence was mixed on changes in abortion care-seeking behaviour. More work is needed to ensure that women seek safe abortion services in lieu of informal services that may be more likely to lead to postabortion complications. PMID:28237953

Punishments and Prizes for Explaining Global Warming

2006-12-01

Some few gifted scientists, the late Carl Sagan being an iconic example, are superbly skilled at communicating science clearly and compellingly to non-scientists. Most scientists, however, have serious shortcomings as communicators. The common failings include being verbose, addicted to jargon, caveat- obsessed and focused on details. In addition, it is far easier for a scientist to scoff at the scientific illiteracy of modern society than to work at understanding the viewpoints and concerns of journalists, policymakers and the public. Obstacles await even those scientists with the desire and the talent to communicate science well. Peer pressure and career disincentives can act as powerful deterrents, discouraging especially younger scientists from spending time on non-traditional activities. Scientists often lack mentors and role models to help them develop skills in science communication. Journalists also face real difficulties in getting science stories approved by editors and other gatekeepers. Climate change science brings its own problems in communication. The science itself is unusually wide- ranging and complex. The contentious policies and politics of dealing with global warming are difficult to disentangle from the science. Misinformation and disinformation about climate change are widespread. Intimidation and censorship of scientists by some employers is a serious problem. Polls show that global warming ranks low on the public's list of important issues. Despite all the obstacles, communicating climate change science well is critically important today. It is an art that can be learned and that brings its own rewards and satisfactions. Academic institutions and research funding agencies increasingly value outreach by scientists, and they provide resources to facilitate it. Society needs scientists who can clearly and authoritatively explain the science of global warming and its implications, while remaining objective and policy-neutral. This need will only increase in coming years as climate change makes the transition from a topic of limited public interest to one of great concern to all society.

Psychometric properties and initial validity of the Brief Observation of Social Communication Change (BOSCC), a measure of treatment-response for social-communication behaviors, are described. The BOSCC coding scheme is applied to 177 video observations of 56 young children with ASD and minimal language abilities. The BOSCC has high to excellent inter-rater and test-retest reliability and shows convergent validity with measures of language and communication skills. The BOSCC Core total demonstrates statistically significant amounts of change over time compared to a no change alternative while the ADOS CSS over the same period of time did not. This work is a first step in the development of a novel outcome measure for social-communication behaviors with applications to clinical trials and longitudinal studies.

Hydrologic Design in the Anthropocene

NASA Astrophysics Data System (ADS)

Vogel, R. M.; Farmer, W. H.; Read, L.

2014-12-01

In an era dubbed the Anthropocene, the natural world is being transformed by a myriad of human influences. As anthropogenic impacts permeate hydrologic systems, hydrologists are challenged to fully account for such changes and develop new methods of hydrologic design. Deterministic watershed models (DWM), which can account for the impacts of changes in land use, climate and infrastructure, are becoming increasing popular for the design of flood and/or drought protection measures. As with all models that are calibrated to existing datasets, DWMs are subject to model error or uncertainty. In practice, the model error component of DWM predictions is typically ignored yet DWM simulations which ignore model error produce model output which cannot reproduce the statistical properties of the observations they are intended to replicate. In the context of hydrologic design, we demonstrate how ignoring model error can lead to systematic downward bias in flood quantiles, upward bias in drought quantiles and upward bias in water supply yields. By reincorporating model error, we document how DWM models can be used to generate results that mimic actual observations and preserve their statistical behavior. In addition to use of DWM for improved predictions in a changing world, improved communication of the risk and reliability is also needed. Traditional statements of risk and reliability in hydrologic design have been characterized by return periods, but such statements often assume that the annual probability of experiencing a design event remains constant throughout the project horizon. We document the general impact of nonstationarity on the average return period and reliability in the context of hydrologic design. Our analyses reveal that return periods do not provide meaningful expressions of the likelihood of future hydrologic events. Instead, knowledge of system reliability over future planning horizons can more effectively prepare society and communicate the likelihood of future hydrologic events of interest.

Is Communication a Mechanism of Relationship Education Effects among Rural African Americans?

2017-10-01

Enhancing communication as a means of promoting relationship quality has been increasingly questioned, particularly for couples at elevated sociodemographic risk. In response, the current study investigated communication change as a mechanism accounting for changes in relationship satisfaction and confidence among 344 rural, predominantly low-income African American couples with an early adolescent child who participated in a randomized controlled trial of the Protecting Strong African American Families (ProSAAF) program. Approximately 9 months after baseline assessment, intent-to-treat analyses indicated ProSAAF couples demonstrated improved communication, satisfaction, and confidence compared with couples in the control condition. Improvements in communication mediated ProSAAF effects on relationship satisfaction and confidence; conversely, neither satisfaction nor confidence mediated intervention effects on changes in communication. These results underscore the short-term efficacy of a communication-focused, culturally sensitive prevention program and suggest that communication is a possible mechanism of change in relationship quality among low-income African American couples.

Due, perhaps, to the historical division of crowd dynamics research into psychological and engineering approaches, microscopic crowd models have tended toward modelling simple interchangeable particles with an emphasis on the simulation of physical factors. Despite the fact that people have complex (non-panic) behaviours in crowd disasters, important human factors in crowd dynamics such as information discovery and processing, changing goals and communication have not yet been well integrated at the microscopic level. We use our Microscopic Human Factors methodology to fuse a microscopic simulation of these human factors with a popular microscopic crowd model. By tightly integrating human factors with the existing model we can study the effects on the physical domain (movement, force and crowd safety) when human behaviour (information processing and communication) is introduced. In a large-room egress scenario with ample exits, information discovery and processing yields a crowd of non-interchangeable individuals who, despite close proximity, have different goals due to their different beliefs. This crowd heterogeneity leads to complex inter-particle interactions such as jamming transitions in open space; at high crowd energies, we found a freezing by heating effect (reminiscent of the disaster at Central Lenin Stadium in 1982) in which a barrier formation of naïve individuals trying to reach blocked exits prevented knowledgeable ones from exiting. Communication, when introduced, reduced this barrier formation, increasing both exit rates and crowd safety.

Organizations are redesigning models of care in today's rapidly changing health care environment. Using proven innovation techniques maximizes likelihood of effective change. Our safety-net hospital aims to reduce high emergency department visit, admission, and readmission rates, key components to health care cost control. Twenty-five clinical stakeholders participated in mixed-methods innovation exercises to understand stakeholders, frame problems, and explore solutions. We identified existing barriers and means to improve post-emergency department/post-inpatient discharge care coordination/communication among patient-centered medical home care team members, including patients. Physicians and staff preferred automated e-mail notifications, including patient identifiers, medical home/primary care provider information, and relevant clinical documentation, to improve communication efficiency/efficacy.

Although the link between social factors and health-related outcomes has long been widely acknowledged, the mechanisms characterizing this link are relatively less known and remain a subject of continued investigation across disciplines. In this study, drawing on the structural influence model of health communication, the hypothesis that differences in concern about and information needs on HIV/AIDS, HIV/AIDS-related media use, and perceived salience of HIV/AIDS-related information, characterized as communication inequality, can at least partially mediate the impacts of socioecological (urban vs. rural) and socioeconomic (education) disparities on inequalities in HIV/AIDS knowledge and risk perception was tested. Data were collected from a random sample of 986 urban and rural respondents in northwest Ethiopia. Structural equation modeling, using the maximum likelihood method, was used to test the mediation models. The models showed an adequate fit of the data and hence supported the hypothesis that communication inequality can at least partially explain the causal mechanism linking socioeconomic and socioecological factors with HIV/AIDS knowledge and risk perception. Both urbanity versus rurality and education were found to have significant mediated effects on HIV/AIDS knowledge (urbanity vs. rurality: β = 0.28, p = .001; education: β = 0.08, p = .001) and HIV/AIDS risk perception (urbanity vs. rurality: β = 0.30, p = .001; education: β = 0.09, p = .001). It was concluded that communication inequality might form part of the socioecologically and socioeconomically embedded processes that affect HIV/AIDS-related outcomes. The findings suggest that the media and message effects that are related to HIV/AIDS behavior change communication can be viewed from a structural perspective that moves beyond the more reductionist behavioral approaches upon which most present-day HIV/AIDS communication campaigns seem to be based.

Learn, how to learn

Ernest L. Boyer, in his 1990 book, "Scholarship Reconsidered: Priorities of the Professorate" cites some ground breaking studies and offers a new paradigm that identifies the need to recognize the growing conversation about teaching, scholarship and research in the Universities. The use of `ACORN' model suggested by Hawkins and Winter to conquer and mastering change, may offer some helpful hints for the novice professor, whose primary objective might be to teach students to `learn how to learn'. Action : It is possible to effectively change things only when a teaching professor actually tries out a new idea. Communication : Changes are successful only when the new ideas effectively communicated and implemented. Ownership : Support for change is extremely important and is critical. Only strong commitment for accepting changes demonstrates genuine leadership. Reflection : Feedback helps towards thoughtful evaluation of the changes implemented. Only reflection can provide a tool for continuous improvement. Nurture : Implemented changes deliver results only when nurtured and promoted with necessary support systems, documentation and infrastructures. Inspired by the ACORN model, the author experimented on implementing certain principles of `Total Quality Management' in the classroom. The author believes that observing the following twenty principles would indeed help the student learners how to learn, on their own towards achieving the goal of `Lifelong Learning'. The author uses an acronym : QUOTES : Quality Underscored On Teaching Excellence Strategy, to describe his methods for improving classroom teacher-learner participation. 1. Break down all barriers. 2. Create consistency of purpose with a plan. 3. Adopt the new philosophy of quality. 4. Establish high Standards. 5. Establish Targets / Goals. 6. Reduce dependence on Lectures. 7. Employ Modern Methods. 8. Control the Process. 9. Organize to reach goals. 10. Prevention vs. Correction. 11. Periodic Improvements. 12. Maintain Momentum. 13. Feedback : Communication. 14. Fact - Based Decisions. 15. Exploit Opportunities. 16. Mobilization of Expertise. 17. Drive out Fear. 18. Recognition / Keep Score. 19. Identify Accomplishments. 20. Customer Focus / Results. In conclusion, the author believes that the ACORN model and the QUOTES model may offer some guidelines that would help and enable the instructor to motivate learners to learn on their own.

2017-07-01

A range of communication skills training programmes have been developed targeting trainees in various medical specialties, predominantly in oncology but to a lesser extent in psychiatry. Effective communication is fundamental to the assessment and treatment of psychiatric conditions, but there has been less attention to this in clinical practice for psychiatrists in training. This review examines the outcomes of communication skills training interventions in psychiatric specialty training. The published English-language literature was examined using multiple online databases, grey literature and hand searches. The review was conducted and reported using Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Studies examining the efficacy of communication skills training were included. Randomised controlled trials, pseudo-randomised studies and quasi-experimental studies, as well as observational analytical studies and qualitative studies that met criteria, were selected and critically appraised. No limits were applied for date of publication up until 16 July 2016. Total search results yielded 2574 records. Of these, 12 studies were identified and reviewed. Two were randomised controlled trials and the remaining 10 were one-group pretest/posttest designs or posttest-only designs, including self-report evaluations of communication skills training and objective evaluations of trainee skills. There were no studies with outcomes related to behaviour change or patient outcomes. Two randomised controlled trials reported an improvement in clinician empathy and psychotherapeutic interviewing skills due to specific training protocols focused on those areas. Non-randomised studies showed varying levels of skills gains and self-reported trainee satisfaction ratings with programmes, with the intervention being some form of communication skills training. The heterogeneity of communication skills training is a barrier to evaluating the efficacy of different communication skills training programmes. Further validation studies examining specific models and frameworks would support a stronger evidence base for communication skills training in psychiatry. It remains a challenge to develop research to investigate behaviour change over time in clinical practice or to measure patient outcomes due to the effects of communication skills training.

Breast cancer patients commonly experience sexual concerns, yet rarely discuss them with clinicians. The study examined patient and provider experiences and preferences related to communication about breast cancer-related sexual concerns with the goal of informing intervention development. Patient data (n = 28) were derived from focus groups and interviews with partnered and unpartnered women treated for breast cancer reporting sexual concerns. Provider data (n = 11) came from interviews with breast cancer oncologists and nurse practitioners. Patient and provider data were analyzed separately using the framework method of qualitative analysis. Findings revealed individual and institutional barriers to effective communication about sexual concerns and highlighted key communication facilitators (e.g., a positive patient-provider relationship, patient communication as a driver of provider communication, and vice versa). Patients expressed preferences for open, collaborative communication; providers expressed preferences for focused intervention targets (identifying concerns, offering resources/referrals) and convenient format. A model of effective communication of sexual concerns was developed to inform communication interventions. Findings suggest that to improve patient-provider communication about sexual concerns, knowledge and skills-based interventions that activate patients and that equip providers for effective discussions about sexual concerns are needed, as are institutional changes that could incentivize such discussions.

Fluctuation Dynamics Analysis of gp120 Envelope Protein Reveals a Topologically Based Communication Network

PubMed Central

Shrivastava, Indira; LaLonde, Judith M.

2012-01-01

HIV infection is initiated by binding of the viral glycoprotein gp120, to the cellular receptor CD4. Upon CD4 binding, gp120 undergoes conformational change, permitting binding to the chemokine receptor. Crystal structures of gp120 ternary complex reveal the CD4 bound conformation of gp120. We report here the application of Gaussian Network Model (GNM) to the crystal structures of gp120 bound to CD4 or CD4 mimic and 17b, to study the collective motions of the gp120 core and determine the communication propensities of the residue network. The GNM fluctuation profiles identify residues in the inner domain and outer domain that may facilitate conformational change or stability, respectively. Communication propensities delineate a residue network that is topologically suited for signal propagation from the Phe43 cavity throughout the gp120 outer domain. . These results provide a new context for interpreting gp120 core envelope structure-function relationships. PMID:20718047

Mass media, stigma, and disclosure of HIV test results: multilevel analysis in the Eastern Cape, South Africa.

Hutchinson, P L; Mahlalela, X; Yukich, Josh

2007-12-01

In this article, we examine the role of mass media and interpersonal communication in affecting knowledge of HIV/AIDS, reducing stigma, using condoms, and increasing the likelihood of disclosing HIV test results to sexual partners and family members. Data from a 2002 household survey in the Eastern Cape Province of South Africa are used to measure levels of stigma, interpersonal communication, willingness to disclosure HIV test results and condom use. We use a multilevel framework that accounts for the social context in which individuals access information, gauge social norms, and make decisions about the costs and benefits of HIV testing and disclosure. The results provide support for the positive effects of both media exposure and informal social networks on ideational factors, namely changes in knowledge and stigma, which lead to behavior change. Consistent with common models of health communication dynamics, these latter factors dominate decisions regarding disclosure of HIV test results and condom use.

The Assessment of Climatological Impacts on Agricultural Production and Residential Energy Demand

NASA Astrophysics Data System (ADS)

Cooter, Ellen Jean

The assessment of climatological impacts on selected economic activities is presented as a multi-step, inter -disciplinary problem. The assessment process which is addressed explicitly in this report focuses on (1) user identification, (2) direct impact model selection, (3) methodological development, (4) product development and (5) product communication. Two user groups of major economic importance were selected for study; agriculture and gas utilities. The broad agricultural sector is further defined as U.S.A. corn production. The general category of utilities is narrowed to Oklahoma residential gas heating demand. The CERES physiological growth model was selected as the process model for corn production. The statistical analysis for corn production suggests that (1) although this is a statistically complex model, it can yield useful impact information, (2) as a result of output distributional biases, traditional statistical techniques are not adequate analytical tools, (3) the model yield distribution as a whole is probably non-Gausian, particularly in the tails and (4) there appears to be identifiable weekly patterns of forecasted yields throughout the growing season. Agricultural quantities developed include point yield impact estimates and distributional characteristics, geographic corn weather distributions, return period estimates, decision making criteria (confidence limits) and time series of indices. These products were communicated in economic terms through the use of a Bayesian decision example and an econometric model. The NBSLD energy load model was selected to represent residential gas heating consumption. A cursory statistical analysis suggests relationships among weather variables across the Oklahoma study sites. No linear trend in "technology -free" modeled energy demand or input weather variables which would correspond to that contained in observed state -level residential energy use was detected. It is suggested that this trend is largely the result of non-weather factors such as population and home usage patterns rather than regional climate change. Year-to-year changes in modeled residential heating demand on the order of 10('6) Btu's per household were determined and later related to state -level components of the Oklahoma economy. Products developed include the definition of regional forecast areas, likelihood estimates of extreme seasonal conditions and an energy/climate index. This information is communicated in economic terms through an input/output model which is used to estimate changes in Gross State Product and Household income attributable to weather variability.

Parent-child drug communication: pathway from parents' ad exposure to youth's marijuana use intention.

2014-01-01

The authors combined the 2-step flow of communication model and the theory of planned behavior to create a framework to evaluate the effectiveness of a set of advertisements from the National Youth Anti-Drug Media Campaign promoting parent-child drug communication. The sample consisted of 1,349 pairs of parents and children who responded to the first and second annual rounds of the National Survey of Parents and Youth, and 1,276 pairs from Rounds 3 and 4. Parents' exposure to the campaign reported at Round 1 was indirectly associated with youth's lowered intentions to use marijuana at Round 2. Ad exposure was associated with positive changes in parental attitudes toward drug communication and perceived social approval of antidrug communications. These two beliefs, along with perceived behavioral control, predicted parents' intentions to discuss drugs with their children. Parental intentions to discuss drugs reported at Round 1 were associated with youth's report of actual drug communication with their parents at Round 2. Frequency and breadth of the topics in parent-child drug communication were associated with less positive attitudes toward marijuana use among youth who spoke with their parents. Together, the child's attitudes toward marijuana use and perceived ability to refuse marijuana use predicted youth's intentions to use marijuana. The proposed model fit well with the data and was replicated in a parallel analysis of the data from Rounds 3 and 4. Implications for future antidrug media campaign efforts are discussed.

To examine changes in parent-child communication patterns and their relation to glycemic control and treatment adherence using observational data in a 3-year prospective multisite study of youth with type 1 diabetes aged 9-11 years at baseline and their families (n = 217). Adolescents and caregivers participated in a diabetes problem-solving discussion. Families were rated on negative and positive communication and interactions using the Interaction Behavior Code. Maternal and paternal negative communication decreased over time, whereas adolescent and maternal positive communication and positive reciprocity increased. Baseline preadolescent youth and maternal positive communication predicted adherence 3 years later. Changes in family communication did not predict changes in glycemic control or adherence. During the transition to adolescence, family communication changed in unexpected and positive ways. Additionally, the relationship of baseline family communication to subsequent adherence suggests the need to assess family communication concerning diabetes-related management during preadolescence. © The Author 2014.

Scaling Climate Change Communication for Behavior Change

Ultimately, effective climate change communication results in a change in behavior, whether the change is individual, household or collective actions within communities. We describe two efforts to promote climate-friendly behavior via climate communication and behavior change theory. Importantly these efforts are designed to scale climate communication principles focused on behavior change rather than soley emphasizing climate knowledge or attitudes. Both cases are embedded in rigorous evaluations (randomized controlled trial and quasi-experimental) of primary and secondary outcomes as well as supplementary analyses that have implications for program refinement and program scaling. In the first case, the Girl Scouts "Girls Learning Environment and Energy" (GLEE) trial is scaling the program via a Massive Open Online Course (MOOC) for Troop Leaders to teach the effective home electricity and food and transportation energy reduction programs. The second case, the Alliance for Climate Education (ACE) Assembly Program, is advancing the already-scaled assembly program by using communication principles to further engage youth and their families and communities (school and local communities) in individual and collective actions. Scaling of each program uses online learning platforms, social media and "behavior practice" videos, mastery practice exercises, virtual feedback and virtual social engagement to advance climate-friendly behavior change. All of these communication practices aim to simulate and advance in-person train-the-trainers technologies.As part of this presentation we outline scaling principles derived from these two climate change communication and behavior change programs.

Action research and millennials: Improving pedagogical approaches to encourage critical thinking.

This article examines the effects of intergenerational diversity on pedagogical practice in nursing education. While generational cohorts are not entirely homogenous, certain generational features do emerge. These features may require alternative approaches in educational design in order to maximize learning for millennial students. Action research is employed with undergraduate millennial nursing students (n=161) who are co-researchers in that they are asked for changes in current simulation environments which will improve their learning in the areas of knowledge acquisition, skill development, critical thinking, and communication. These changes are put into place and a re-evaluation of the effectiveness of simulation progresses through three action cycles. Millennials, due to a tendency for risk aversion, may gravitate towards more supportive learning environments which allow for free access to educators. This tendency is mitigated by the educator modeling expected behaviors, followed by student opportunity to repeat the behavior. Millennials tend to prefer to work in teams, see tangible improvement, and employ strategies to improve inter-professional communication. This research highlights the need for nurse educators working in simulation to engage in critical discourse regarding the adequacy and effectiveness of current pedagogy informing simulation design. Pedagogical approaches which maximize repetition, modeling, immersive feedback, and effective communication tend to be favored by millennial students. Copyright © 2017 Elsevier Ltd.

The program aims to develop a robust response to climate change by providing K-16 climate change education; enhance the effectiveness of K-16 education particularly in engineering and other STEM disciplines by use of new instructional technologies; increase the enrollment in engineering programs and the number of engineering degrees awarded by showing engineering's usefulness in relation to the much-discussed contemporary issue of climate change; increase persistence in STEM degrees by providing student research opportunities; and increase the ethnic diversity of those receiving engineering degrees and help ensure an ethnically diverse response to climate change. Students participated in the second summer internship funded by the project. More than 60 students participated in guided research experiences aligned with NASA Science Plan objectives for climate and Earth system science and the educational objectives of the three institutions. The students went through training in modern media technology (webcasts), and in using this technology to communicate the information on climate change to others, especially high school students, culminating in production of webcasts on investigating the aspects of climate change using NASA data. Content developed is leveraged by NASA Earth observation data and NASA Earth system models and tools. Several departments are involved in the educational program.

To bridge the gap between theory and practice, methods are needed that promote a positive attitude to change among health care professionals and facilitate the incorporation of new research findings. In this context, communication plays a significant role. The aim of this study was to analyse primary care staff members' readiness to adopt new ways of thinking and willingness to change their work practices by means of strategic communication. An evaluative design was used to study a primary care staff cohort for 7 years. The study population comprised all primary care staff in a region of Sweden (n = 1206). The strategic communication encompassed managerial impact, planning and implementation of reflexive communication processes, in addition to activities in three established communication channels (oral, written and digital). A questionnaire was used, and bivariate and multivariate statistical analyses were performed. A total of 846 individuals participated in the evaluation (70%). Strategic communication had a significant effect on staff members' new way of thinking (61%) and willingness to change daily work practices (33%). The communication channels had a significant synergy effect on the adoption of new ideas and willingness to change attitudes. Oral and digital communication had a significant impact on staff members' readiness to change. Strategic communication plays an important role in the process of creating innovative attitudes and behaviour among primary care professionals. The willingness to change attitudes enhances primary care staff's readiness to change everyday practices, thus facilitating the implementation of evidence-based care. © 2011 Blackwell Publishing Ltd.

Informations in Models of Evolutionary Dynamics

2016-03-01

Biological organisms adapt to changes by processing informations from different sources, most notably from their ancestors and from their environment. We review an approach to quantify these informations by analyzing mathematical models of evolutionary dynamics and show how explicit results are obtained for a solvable subclass of these models. In several limits, the results coincide with those obtained in studies of information processing for communication, gambling or thermodynamics. In the most general case, however, information processing by biological populations shows unique features that motivate the analysis of specific models.

Defining a Communications Satellite Policy System for the 21st Century: A Model for a International Legal Framework and A New _Code of Conduct_

1996-02-01

This paper addresses the changing international communications environment and explores the key elements of a new policy framework for the 21st Century. It addresses the issues related to changing markets, trade considerations, standards, regulatory changes and international institutions and law. The most important aspects will related to new international policy and regulatory frameworks and in particular to a new international code of ethics and behavior in the field of satellite communications. A new communications satellite policy framework requires systematically addressing the following points: • Multi-lateral agreements at the nation state and the operating entity level • Systematic means to access both private and public capital • Meshing ITU regulations with regional and national policy guidelines including • landing rights" and national allocation procedures. • Systematic approach to local partnerships • Resolving the issue of the relative standing of various satellite systems (i.e. GEO, MEO, and LEO systems) • Resolving the rights, duties, and priorities of satellite facility providers versus types of service prviders. Beyond this policy framework and generalized legal infrastructure there is also another need. This is a need that arises from both increased globalism and competitive international markets. This is what might quite simply be called a "code of reasonable conduct:" To provide global and international communications services effectively and well in the 21st Century will require more than meeting minimum international legal requirements. A new "code of conduct" for global satellite communications will thus likely need to address: • Privacy and surveillance • Ethics of transborder data flow • Censorship and moral values • Cultural and linguistic sensitivity • Freedom of the press and respect for journalistic standards As expanding global information and telecommunications systems grow and impact every aspect of modern life, the need for new international policy and especially new suitable standards of conduct in the field of satellite communications become ever more apparent and necessary.

To determine the effectiveness of a community-partnered risk communication intervention tailored for subsistence anglers in a public housing community. A one group, pretest, posttest design was used to test the effectiveness of the intervention in a sample (n=23, age range 18-75 years, 100% African American) of subsistence anglers residing in a public housing community in close proximity to a Superfund clean-up site. Face-to-face surveys were conducted at baseline and 3 months post the intervention to assess changes in knowledge and behaviors. A socioculturally appropriate risk communication intervention was developed, implemented, and evaluated in the targeted community. The risk communication included an interactive power point presentation, visual demonstration by a role model, and distribution of low literacy written materials, followed by a booster mailing of materials 1 month past the initial intervention. Evaluation measures included survey instruments on knowledge and self-reported fishing behaviors. Participants showed improved knowledge and behavior change related to trimming fish, consumption by pregnant women and children, and consumption of large fish. The sociocultured tailored risk communication intervention demonstrated promising outcomes in this community and should be evaluated in a larger population of subsistence anglers.

"The first step is admitting you have a problem…": the process of advancing science communication in Landscape Conservation Cooperatives in Alaska

Climate change is impacting ecological systems, coastal processes, and environmental disturbance regimes in Alaska, leading to a pressing need to communicate reliable scientific information about climate change, its impacts, and future projections for land and resource management and decision-making. However, little research has been done to dissect and analyze the process of making the results of scientific inquiry directly relevant and usable in resource management. Based within the Science Application division of the US Fish and Wildlife Service, Landscape Conservation Cooperatives (LCCs) are regional conservation science partnerships that provide scientific and technical expertise needed to support conservation planning at landscape scales and promote collaboration in defining shared conservation goals. The five LCCs with jurisdiction in Alaska recently held a training workshop with the goals of advancing staff understanding and skills related to science communication and translation. We report here preliminary results from analysis of workshop discussions and pre- and post- workshop interviews and surveys revealing expectations, assumptions, and mental models regarding science communication and the process of conducting use-inspired science. Generalizable conclusions can assist scientists and boundary organizations bridge knowledge gaps between science and resource management.

Local governments across the US use historic data to approve capital improvement projects and update comprehensive/zoning plans. Due to the effects of climate change, historic data sets are no longer suitable, which requires communities to use climate models to project the future. However, the use of climate models also presents challenges for local governments such as: Variations between models: Because model-development methodologies vary, different climate models provide different end results. A local governments' decision concerning which climate model to use is tricky because the model drives policy direction and infrastructure investments that can be both expensive and controversial. Communicating the gaps of a model: There are always uncertainties associated with modeling. These gaps may range from the scale of a model to the type of data used in modeling. Effectively communicating this to a community is crucial to gain political support. Managing politics associated with using a model: In many cases, models project changes to the built environment that will detrimentally affect private property owners. This can result in strong push back from the community and could threaten the local tax base. Scientists have important roles; from development to delivery of models to assisting local governments navigate through these challenges. Bringing in entities with experience of working with local governments can contribute to a successful outcome. In this proposed session, ICLEI-Local Governments for Sustainability will use the USGS CoSMoS as a case study for lessons learned in establishing a framework for effective collaboration between local governments and the science community.

Interprofessional communication and collaboration are promoted by policymakers as fundamental building blocks for improving patient safety and meeting the demands of increasingly complex care. This paper reports qualitative findings of an interprofessional intervention designed to improve communication and collaboration between different professions in general internal medicine (GIM) hospital wards in Canada. The intervention promoted self-introduction by role and profession to a collaborating colleague in relation to the shared patient, a question or communication regarding the patient, to be followed by an explicit request for feedback from the partner professional. Implementation and uptake of the intervention were evaluated using qualitative methods, including 90 hours of ethnographic observations and interviews collected in both intervention and comparison wards. Documentary data were also collected and analysed. Fieldnotes and interviews were transcribed and analysed thematically. Our findings suggested that the intervention did not produce the anticipated changes in communication and collaboration between health professionals, and allowed us to identify barriers to the implementation of effective collaboration interventions. Despite initially offering verbal support, senior physicians, nurses, and allied health professionals minimally explained the intervention to their junior colleagues and rarely role-modelled or reiterated support for it. Professional resistances as well as the fast paced, interruptive environment reduced opportunities or incentive to enhance restrictive interprofessional relationships. In a healthcare setting where face-to-face spontaneous interprofessional communication is not hostile but is rare and impersonal, the perceived benefits of improvement are insufficient to implement simple and potentially beneficial communication changes, in the face of habit, and absence of continued senior clinician and management support.

Communication problems impede effective symptom management during chemotherapy. The primary aim of this pilot randomized controlled trial was to test the effects of a personal digital assistant-delivered communication intervention on pain, depression, and fatigue symptoms among breast cancer patients undergoing chemotherapy. Secondary aims included assessment of 1) study feasibility, 2) patient and clinician responses to study participation, and 3) intervention effects on health-related quality of life (HRQoL) and communication self-efficacy. Intervention group participants (n = 27) completed symptom inventories at baseline, once per week during treatment, and at posttreatment. Depending on symptom severity, they viewed race-concordant videos on how to communicate about pain, depression and/or fatigue, using the personal digital assistant. Symptom records were tracked and shared with clinicians. Control group participants (n = 23) received usual care. Longitudinal random effects modeling assessed the changes in average symptom scores over time. Descriptive statistics assessed study feasibility and intervention effects on HRQoL and communication self-efficacy. Postintervention focus groups, interviews, and surveys assessed responses to study participation. Mean age of the participants was 51.0 years; 42 participants (84%) were white. In comparison with control, intervention group participants reported lower average pain severity over time (P = .015). Mean pain interference scores over time were marginally different between groups (P = .07); mean depression and fatigue scores over time were statistically nonsignificant. Feasibility outcomes and perspectives about study participation were positive. Mean pre-post decreases in HRQoL were generally higher among intervention group participants; pre-post changes in communication self-efficacy were equivalent. Mixed findings of the study indicate the need for future research.

Changes in Marital and Partner Relationships in the Aftermath of Hurricane Katrina: An Analysis With Low-Income Women

Lowe, Sarah R.; Rhodes, Jean E.; Scoglio, Arielle A. J.

2012-01-01

Little is known about the impact of natural disasters on marital and partner relationships. In this study, the authors aimed to fill this gap by investigating the changes in such relationships in a sample of 40 low-income, mostly African American women who survived Hurricane Katrina. Through in-depth interviews, participants described how the hurricane affected their intimate relationships. The authors found that, although many participants reported negative changes in their relationships, others reported that their relationships grew stronger, often despite initial strain. As a framework for understanding the processes underlying participants’ negative and positive outcomes, the authors drew on the family stress model. Consistent with the model, participants reported that the hurricane led to external stressors, including unemployment and prolonged separations, and that these stressors, in turn, undermined both individual functioning and relational processes (e.g., communication and support). Conversely, participants reporting positive changes experienced new employment opportunities, a greater sense of perspective, and high levels of effective communication and support in their relationships. Based on the findings, policies that reduce the economic strain of low-income families in the aftermath of disasters and empirically supported, culturally sensitive, clinical interventions for individuals and couples are recommended.

Researchers from the Center for Research on Environmental Decisions (CRED) published "The Psychology of Climate Change Communication: A Guide for Scientists, Journalists, Educators, Political Aides, and the Interested Public" in 2009. This landmark guide provided climate change communicators a synthesis of the social science research that was pertinent to understanding how people think about climate change and how the practice could be improved. In the fall of 2014 this guide will be rereleased, with a new title, and in a partnership between CRED and ecoAmerica. The updated guide addresses how and why Americans respond in certain ways to climate change and explains how communicators can apply best practices to their own work. The guide, which includes research from a range of social science fields including psychology, anthropology, communications, and behavioral economics, is designed to be useful for experienced and novice communicators alike. Included in the guide are strategies to boost engagement, common mistakes to avoid, and best practices that organizations around the world have used to meaningfully engage individuals and groups on climate change. The proposed presentation will provide an overview of the main findings and tips from the 2014 climate change communication guide. It will provide a deeper look at a few of the key points that are crucial for increasing audience engagement with climate change including understanding how identity shapes climate change, how to lead with solutions, and how to bring the impacts of climate change close to home. It will highlight tips for motivating positive behavior change that will lead people down the path toward solutions. Finally, it will address the benefits and challenges associated with producing a communication guide and insight into synthesizing social science research findings into a usable format for a variety of audiences.

Behavioural divergence, interfertility and speciation: a review.

PubMed

Pillay, Neville; Rymer, Tasmin L

2012-11-01

Behavioural compatibility between mates is fundamental for maintaining species boundaries and is achieved through appropriate communication between males and females. A breakdown in communication will lead to behavioural divergence and reduced interfertility. In this review, we summarise the current knowledge on male signals and female perception of these signals, integrating the literature from several taxa. We advocate that signaller-perceiver coevolution, which is usually under strong stabilising selection to enable mating, forms the basis of species-specific mate recognition systems. The mechanisms (phylogeny, geography, ecology, biology) shaping signaller-perceiver systems are briefly discussed to demonstrate the factors underpinning the evolution of signaller-perceiver couplings. Since divergence and diversification of communication systems is driven by changes in the mechanical properties of sensory pathways and morphology of sensory organs, we highlight signal modalities (auditory, olfactory, visual, tactile) and their importance in communication, particularly in mate selection. Next, using available examples and generating a stylised model, we suggest how disruption (biological, ecological, stochastic) of signaller-perceiver systems drives behavioural divergence and consequently results in reduced interfertility and speciation. Future studies should adopt an integrative approach, combining multiple parameters (phylogeny, adaptive utility of communication systems, genetics and biomechanical/biochemical properties of signals and perception) to explore how disruption of signaller-perceiver systems results in behavioural divergence and reduced interfertility. Finally, we question the impact that rapid environmental change will have on disruption of communication systems, potentially interfering with signaller-perceiver couplings.

2016-12-01

Several studies show that healthcare professionals need to communicate inter-professionally in order to manage ethical difficulties. A model of clinical ethics support (CES) inspired by Habermas' theory of discourse ethics has been developed by our research group. In this version of CES sessions healthcare professionals meet inter-professionally to communicate and reflect on ethical difficulties in a cooperative manner with the aim of reaching communicative agreement or reflective consensus. In order to understand the course of action during CES, the aim of this study was to describe the communication of value conflicts during a series of inter-professional CES sessions. Ten audio- and video-recorded CES sessions were conducted over eight months and were analyzed by using the video analysis tool Transana and qualitative content analysis. The results showed that during the CES sessions the professionals as a group moved through the following five phases: a value conflict expressed as feelings of frustration, sharing disempowerment and helplessness, the revelation of the value conflict, enhancing realistic expectations, seeing opportunities to change the situation instead of obstacles. In the course of CES, the professionals moved from an individual interpretation of the situation to a common, new understanding and then to a change in approach. An open and permissive communication climate meant that the professionals dared to expose themselves, share their feelings, face their own emotions, and eventually arrive at a mutual shared reality. The value conflict was not only revealed but also resolved.

Communication is of the utmost importance for effective teamwork, yet promoting effective communication and overcoming the cultural belief that conflict is "bad" are key challenges for leaders. To provide optimal patient care, perioperative nurse leaders should assess the culture in which they work and develop strategies to build solid credible relationships within their teams. This article introduces the Complex Adaptive Leadership Model, which has underpinnings in complexity science, as a means to promote culture change and promote productive conflict. The concepts and relationships presented in this model reflect real-world situations and provide strategies for leadership and team development. This model was implemented at one Pennsylvania facility and led to improved outcomes in the perioperative arena related to the Surgical Care Improvement Project indicators during a one-year period.

Temperament, Speech and Language: An Overview

Conture, Edward G.; Kelly, Ellen M.; Walden, Tedra A.

2013-01-01

The purpose of this article is to discuss definitional and measurement issues as well as empirical evidence regarding temperament, especially with regard to children's (a)typical speech and language development. Although all ages are considered, there is a predominant focus on children. Evidence from considerable empirical research lends support to the association between temperament, childhood development and social competence. With regard to communication disorders, extant literature suggests that at least certain elements of temperament (e.g., attention regulation, inhibitory control) are associated with the presence of certain communication disorders. However, the precise nature of this association remains unclear. Three possible accounts of the association between temperament and speech-language disorder are presented. One, the disability model (i.e., certain disorders impact psychological processes leading to changes in these processes, personality, etc., Roy & Bless, 2000a) suggests speech-language disorders may lead to or cause changes in psychological or temperamental characteristics. The disability account cannot be categorically refuted based on currently available research findings. The (pre)dispositional or vulnerability model (i.e., certain psychological processes directly cause the disorder or indirectly modify the course or expression of the disorder, Roy & Bless, 2000a) suggests that psychological or temperamental characteristics may lead to or cause changes in speech-language disorders. The vulnerability account has received some empirical support with regard to stuttering and voice disorders but has not received widespread empirical testing for most speech-language disorders. A third, interaction account, suggests that “disability” and ““vulnerability” may both impact communication disorders in a complex, dynamically-changing manner, a possibility that must await further empirical study. Suggestions for future research directions are provided. PMID:23273707

Background Excellent communication is a necessary component of high-quality health care. We aimed to determine whether a training module could improve patients’ perceptions of physician communication behaviors, as measured by change over time in domains of patient experience scores related to physician communication. Study design We designed a comprehensive physician-training module focused on improving specific “etiquette-based” physician communication skills through standardized simulations and physician coaching with structured feedback. We employed a quasi-experimental pre-post design, with an intervention group consisting of internal medicine hospitalists and residents and a control group consisting of surgeons. The outcome was percent “always” scores for questions related to patients’ perceptions of physician communication using the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey and a Non-HCAHPS Physician-Specific Patient Experience Survey (NHPPES) administered to patients cared for by hospitalists. Results A total of 128 physicians participated in the simulation. Responses from 5020 patients were analyzed using HCAHPS survey data and 1990 patients using NHPPES survey data. The intercept shift, or the degree of change from pre-intervention percent “always” responses, for the HCAHPS questions of doctors “treating patients with courtesy” “explaining things in a way patients could understand,” and “overall teamwork” showed no significant differences between surgical control and hospitalist intervention patients. Adjusted NHPPES percent excellent survey results increased significantly post-intervention for the questions of specified individual doctors “keeping patient informed” (adjusted intercept shift 9.9% P = 0.019), “overall teamwork” (adjusted intercept shift 11%, P = 0.037), and “using words the patient could understand” (adjusted intercept shift 14.8%, p = 0.001). Conclusion A simulation based physician communication coaching method focused on specific “etiquette-based” communication behaviors through a deliberate practice framework was not associated with significantly improved HCAHPS physician communication patient experience scores. Further research could reveal ways that this model affects patients’ perceptions of physician communication relating to specific physicians or behaviors. PMID:28678872

From transitions to transformation - A study of pharmacists developing patient-centered communication skills.

PubMed

Luetsch, Karen; Burrows, Judith

2017-08-12

Pharmacists' communication with patients often focuses on technical aspects of advice giving, while limiting socio-emotional content. To develop pharmacists' patient-centered communication a learning and practice module integrating motivational interviewing (MI) was designed for an online postgraduate program, and its impact on their self-described practice evaluated. To investigate whether training in patient-centered communication changes pharmacists' perceptions of communicating with patients, and how any changes in their communication style influenced interactions and relationships with patients. A descriptive, qualitative study analyzing reflective journal entries detailing pharmacists' experiences of implementing patient-centered communication in practice was designed, evaluating reflections on initial patient interactions after training and 9-12 weeks later. Using the framework method of content and thematic analysis, an evaluation framework was devised that integrated communication, change and learning theories. Reflections were categorized within the framework as transitional (e.g. using good communication skills), transactional (e.g. using MI techniques, achieving reciprocity) or transformational (e.g. describing transformative learning, changing frames of reference in understanding of patient-centeredness). Differences between the first and last journal entries were evaluated and analyzed using descriptive statistics. Eighty-nine pharmacists provided two reflective journal entries for evaluation. Over 9-12 weeks, pharmacists described a change in their perspective of patient-centeredness, how they expanded the socio-emotional aspects of communication and succeeded in difficult conversations. When applying the thematic evaluation framework to initial journal entries, 38 (42%) of reflections fell within the transitional category, 51 (58%) were deemed transactional and none transformational. This changed to 10 (11%) transitional, 45 (51%) transactional and 34 (38%) transformational. Differences were observed between journal entries from pharmacists who studied completely online and those who also attended a workshop. Learning and practicing techniques of MI and person-focused communication changed many pharmacists' frames of reference in regards to patient-centeredness and their self-reported communication style with patients.

A systematic review relevant to the following research questions was conducted (1) the extent to which different theoretical frameworks have been applied to food risk/benefit communication and (2) the impact such food risk/benefit communication interventions have had on related risk/benefit attitudes and behaviors. Fifty four papers were identified. The analysis revealed that (primarily European or US) research interest has been relatively recent. Certain food issues were of greater interest to researchers than others, perhaps reflecting the occurrence of a crisis, or policy concern. Three broad themes relevant to the development of best practice in risk (benefit) communication were identified: the characteristics of the target population; the contents of the information; and the characteristics of the information sources. Within these themes, independent and dependent variables differed considerably. Overall, acute risk (benefit) communication will require advances in communication process whereas chronic communication needs to identify audience requirements. Both citizen's risk/benefit perceptions and (if relevant) related behaviors need to be taken into account, and recommendations for behavioral change need to be concrete and actionable. The application of theoretical frameworks to the study of risk (benefit) communication was infrequent, and developing predictive models of effective risk (benefit) communication may be contingent on improved theoretical perspectives.

The new norms of food waste at the curb: Evidence-based policy tools to address benefits and barriers.

PubMed

Geislar, Sally

2017-10-01

Cities around the world are under increasing political pressure to develop organics collection programs (OCP) to curb the flow of food waste into landfills, reduce the associated greenhouse gases, and generate compost or biogas. While OCPs tend to focus on infrastructure, they often overlook the linchpin role that household behavior change plays in the success of OCPs. The current research used a longitudinal field experiment (n=370) to test both the effectiveness of a new curbside OCP and new social innovations intended to stimulate pro-environmental changes in household behavior. The findings suggest greater participation levels occur by implementing both new supportive infrastructure (i.e., curbside carts and collection services), and innovations that target the social aspects of waste (i.e., communicating social norms of separation). The data also provide an opportunity to test new model for predicting the most efficacious behavior-change interventions based on population profiles. The results provide some support for the model; reducing barriers (i.e., curbside carts and collection) tends to help all population profiles, but norm communication increases participation more for the hypothesized profile than for other sub-groups.

Phoenix, Michelle; Rosenbaum, Peter; Watson, Denise; Camden, Chantal

2016-01-01

Pediatric rehabilitation centers constantly reorganize services to accommodate changes in funding, client needs, evidence-based practices, accountability requirements, theoretical models, and values. However, there are few service delivery models or descriptions of how organizations plan for change to guide organizations through this complex task. This case report presents the "5Rs of Reorganization," a novel process for planning service delivery reorganization projects in pediatric rehabilitation centers. The 5Rs include: 1. Recognize the need for change, 2. Reallocate resources for project management, 3. Review the reality of clients, service delivery, and the community, 4. Reconstruct reality, and 5. Report results. The implementation and outcomes of the "5Rs of Reorganization" process are described for one pediatric rehabilitation center to illustrate how use of this process led to effective service delivery reorganization planning. The resulting multi-component customized service delivery plan reflects high levels of stakeholder involvement. Principles of project management can be applied to support service delivery reorganization planning within pediatric rehabilitation centers using the "5Rs of Reorganization." Strong communication throughout the planning phase is key to developing and sharing a plan for service delivery reorganization. Communication can be supported through use of the 5R process.

Development of a behaviour change intervention: a case study on the practical application of theory.

Use of theory in implementation of complex interventions is widely recommended. A complex trial intervention, to enhance self-management support for people with osteoarthritis (OA) in primary care, needed to be implemented in the Managing Osteoarthritis in Consultations (MOSAICS) trial. One component of the trial intervention was delivery by general practitioners (GPs) of an enhanced consultation for patients with OA. The aim of our case study is to describe the systematic selection and use of theory to develop a behaviour change intervention to implement GP delivery of the enhanced consultation. The development of the behaviour change intervention was guided by four theoretical models/frameworks: i) an implementation of change model to guide overall approach, ii) the Theoretical Domains Framework (TDF) to identify relevant determinants of change, iii) a model for the selection of behaviour change techniques to address identified determinants of behaviour change, and iv) the principles of adult learning. Methods and measures to evaluate impact of the behaviour change intervention were identified. The behaviour change intervention presented the GPs with a well-defined proposal for change; addressed seven of the TDF domains (e.g., knowledge, skills, motivation and goals); incorporated ten behaviour change techniques (e.g., information provision, skills rehearsal, persuasive communication); and was delivered in workshops that valued the expertise and professional values of GPs. The workshops used a mixture of interactive and didactic sessions, were facilitated by opinion leaders, and utilised 'context-bound communication skills training.' Methods and measures selected to evaluate the behaviour change intervention included: appraisal of satisfaction with workshops, GP report of intention to practise and an assessment of video-recorded consultations of GPs with patients with OA. A stepped approach to the development of a behaviour change intervention, with the utilisation of theoretical frameworks to identify determinants of change matched with behaviour change techniques, has enabled a systematic and theory-driven development of an intervention designed to enhance consultations by GPs for patients with OA. The success of the behaviour change intervention in practice will be evaluated in the context of the MOSAICS trial as a whole, and will inform understanding of practice level and patient outcomes in the trial.

Katrina (a tropical cyclone/hurricane) began to strengthen reaching a Category 5 storm on 28th August, 2005 and its winds reached peak intensity of 175 mph and pressure levels as low as 902 mb. Katrina eventually weakened to a category 3 storm and made a landfall in Plaquemines Parish, Louisiana, Gulf of Mexico, south of Buras on 29th August 2005. We investigate the time series intensity change of the hurricane Katrina using environmental modeling and technology tools to develop an early and advanced warning and prediction system. Environmental Mesoscale Model (Weather Research Forecast, WRF) simulations are used for prediction of intensity change and track of the hurricane Katrina. The model is run on a doubly nested domain centered over the central Gulf of Mexico, with grid spacing of 90 km and 30 km for 6 h periods, from August 28th to August 30th. The model results are in good agreement with the observations suggesting that the model is capable of simulating the surface features, intensity change and track and precipitation associated with hurricane Katrina. We computed the maximum vertical velocities (Wmax) using Convective Available Kinetic Energy (CAPE) obtained at the equilibrium level (EL), from atmospheric soundings over the Gulf Coast stations during the hurricane land falling for the period August 21–30, 2005. The large vertical atmospheric motions associated with the land falling hurricane Katrina produced severe weather including thunderstorms and tornadoes 2–3 days before landfall. The environmental modeling simulations in combination with sounding data show that the tools may be used as an advanced prediction and communication system (APCS) for land falling tropical cyclones/hurricanes.

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

Making a difference: incorporating theories of autonomy into models of informed consent.

PubMed

Delany, C

2008-09-01

Obtaining patients' informed consent is an ethical and legal obligation in healthcare practice. Whilst the law provides prescriptive rules and guidelines, ethical theories of autonomy provide moral foundations. Models of practice of consent, have been developed in the bioethical literature to assist in understanding and integrating the ethical theory of autonomy and legal obligations into the clinical process of obtaining a patient's informed consent to treatment. To review four models of consent and analyse the way each model incorporates the ethical meaning of autonomy and how, as a consequence, they might change the actual communicative process of obtaining informed consent within clinical contexts. An iceberg framework of consent is used to conceptualise how ethical theories of autonomy are positioned and underpin the above surface, and visible clinical communication, including associated legal guidelines and ethical rules. Each model of consent is critically reviewed from the perspective of how it might shape the process of informed consent. All four models would alter the process of obtaining consent. Two models provide structure and guidelines for the content and timing of obtaining patients' consent. The two other models rely on an attitudinal shift in clinicians. They provide ideas for consent by focusing on underlying values, attitudes and meaning associated with the ethical meaning of autonomy. The paper concludes that models of practice that explicitly incorporate the underlying ethical meaning of autonomy as their basis, provide less prescriptive, but more theoretically rich guidance for healthcare communicative practices.

Cognitive Network Modeling as a Basis for Characterizing Human Communication Dynamics and Belief Contagion in Technology Adoption

Hutto, Clayton; Briscoe, Erica; Trewhitt, Ethan

2012-01-01

Societal level macro models of social behavior do not sufficiently capture nuances needed to adequately represent the dynamics of person-to-person interactions. Likewise, individual agent level micro models have limited scalability - even minute parameter changes can drastically affect a model's response characteristics. This work presents an approach that uses agent-based modeling to represent detailed intra- and inter-personal interactions, as well as a system dynamics model to integrate societal-level influences via reciprocating functions. A Cognitive Network Model (CNM) is proposed as a method of quantitatively characterizing cognitive mechanisms at the intra-individual level. To capture the rich dynamics of interpersonal communication for the propagation of beliefs and attitudes, a Socio-Cognitive Network Model (SCNM) is presented. The SCNM uses socio-cognitive tie strength to regulate how agents influence--and are influenced by--one another's beliefs during social interactions. We then present experimental results which support the use of this network analytical approach, and we discuss its applicability towards characterizing and understanding human information processing.

Complex Causal Process Diagrams for Analyzing the Health Impacts of Policy Interventions

PubMed Central

Joffe, Michael; Mindell, Jennifer

2006-01-01

Causal diagrams are rigorous tools for controlling confounding. They also can be used to describe complex causal systems, which is done routinely in communicable disease epidemiology. The use of change diagrams has advantages over static diagrams, because change diagrams are more tractable, relate better to interventions, and have clearer interpretations. Causal diagrams are a useful basis for modeling. They make assumptions explicit, provide a framework for analysis, generate testable predictions, explore the effects of interventions, and identify data gaps. Causal diagrams can be used to integrate different types of information and to facilitate communication both among public health experts and between public health experts and experts in other fields. Causal diagrams allow the use of instrumental variables, which can help control confounding and reverse causation. PMID:16449586

Multi-Agent Cooperative Target Search

This paper addresses a vision-based cooperative search for multiple mobile ground targets by a group of unmanned aerial vehicles (UAVs) with limited sensing and communication capabilities. The airborne camera on each UAV has a limited field of view and its target discriminability varies as a function of altitude. First, by dividing the whole surveillance region into cells, a probability map can be formed for each UAV indicating the probability of target existence within each cell. Then, we propose a distributed probability map updating model which includes the fusion of measurement information, information sharing among neighboring agents, information decay and transmission due to environmental changes such as the target movement. Furthermore, we formulate the target search problem as a multi-agent cooperative coverage control problem by optimizing the collective coverage area and the detection performance. The proposed map updating model and the cooperative control scheme are distributed, i.e., assuming that each agent only communicates with its neighbors within its communication range. Finally, the effectiveness of the proposed algorithms is illustrated by simulation. PMID:24865884

The message development tool: a case for effective operationalization of messaging in social marketing practice.

Mattson, Marifran; Basu, Ambar

2010-07-01

That messages are essential, if not the most critical component of any communicative process, seems like an obvious claim. More so when the communication is about health--one of the most vital and elemental of human experiences (Babrow & Mattson, 2003). Any communication campaign that aims to change a target audience's health behaviors needs to centralize messages. Even though messaging strategies are an essential component of social marketing and are a widely used campaign model, health campaigns based on this framework have not always been able to effectively operationalize this key component, leading to cases where initiating and sustaining prescribed health behavior has been difficult (MacStravic, 2000). Based on an examination of the VERB campaign and an Australian breastfeeding promotion campaign, we propose a message development tool within the ambit of the social marketing framework that aims to extend the framework and ensure that the messaging component of the model is contextualized at the core of planning, implementation, and evaluation efforts.

Exploring a Model of Symbolic Social Communication: The Case of ‘Magic’ Johnson

PubMed Central

FLORA, JUNE A.; SCHOOLER, CAROLINE; MAYS, VICKIE M.; COCHRAN, SUSAN D.

2009-01-01

We propose a model of symbolic social communication to explain the process whereby sociocultural identity mediates relationships among receivers, sources and messages to shape message effects. This exploratory study examines how two at-risk groups of African American men responded to various HIV prevention messages delivered by celebrity and professional sources. We interviewed 47 men from a homeless shelter and 50 male college students. Members of both groups were likely to select Johnson as the best person to deliver HIV prevention messages among a list of African American celebrity and professional sources. Results suggest the symbolic meanings embedded in celebrities and message topics are important and enduring influences on message effects. The images and ideas that a source represents are transferred to the advocated behavior, attitude or knowledge change and thus shape how messages are interpreted and received. Further understanding of how culture influences the effects of persuasive messages is critical for the improvement of health-communication campaigns. PMID:22011997

Achieving adoption, use, and integration of information and communication technology by healthcare clinicians in the workplace is recognized as a challenge that requires a multifaceted approach. This article explores community health nurses' engagement with information and communication technology as part of a larger research project that investigated the delivery of self-management support to people with chronic obstructive pulmonary disease. Following a survey of computer skills, participants were provided with computer training to support use of the project information system. Changes in practice were explored using action research meetings and individual semistructured interviews. Results highlight three domains that affected nurses' acceptance, utilization, and integration of information and communication technology into practice; environmental issues; factors in building capacity, confidence, and trust in the technology; and developing competence. Nurses face individual and practice challenges when attempting to integrate new processes into work activities, and the use of participatory models to support adoption is recommended.

This study aimed to compare the effectiveness of a high-intensity model (HIM) and a low-intensity model (LIM) of behaviour change communication interventions in Bihar and Jharkhand states of India designed to improve women's knowledge and usage of safe abortion services, as well as the dose effect of intervention exposure. We conducted two cross-sectional household surveys among married women aged 15-49 years in intervention and comparison districts. Difference-in-difference models were used to assess the efficacy of the intervention, adjusting for sociodemographic characteristics. Although both intervention types improved abortion knowledge, the HIM intervention was more effective in improving comprehensive knowledge about abortion. In particular, there were improvements in knowledge on legality of abortion (AOR=2.2; 95% CI 1.6 to 2.9) and nearby sources of safe abortion care (AOR=1.7; 95% CI 1.2 to 1.3). Higher level of exposure to abortion-related messages was related to more accurate knowledge about abortion within both intervention groups. Evidence was mixed on changes in abortion care-seeking behaviour. More work is needed to ensure that women seek safe abortion services in lieu of informal services that may be more likely to lead to postabortion complications.

We investigated cross-level effects, which are concurrent changes across neural and cognitive-behavioral levels of analysis as teams interact, between neurophysiology and team communication variables under variations in team training. When people work together as a team, they develop neural, cognitive, and behavioral patterns that they would not develop individually. It is currently unknown whether these patterns are associated with each other in the form of cross-level effects. Team-level neurophysiology and latent semantic analysis communication data were collected from submarine teams in a training simulation. We analyzed whether (a) both neural and communication variables change together in response to changes in training segments (briefing, scenario, or debriefing), (b) neural and communication variables mutually discriminate teams of different experience levels, and (c) peak cross-correlations between neural and communication variables identify how the levels are linked. Changes in training segment led to changes in both neural and communication variables, neural and communication variables mutually discriminated between teams of different experience levels, and peak cross-correlations indicated that changes in communication precede changes in neural patterns in more experienced teams. Cross-level effects suggest that teamwork is not reducible to a fundamental level of analysis and that training effects are spread out across neural and cognitive-behavioral levels of analysis. Cross-level effects are important to consider for theories of team performance and practical aspects of team training. Cross-level effects suggest that measurements could be taken at one level (e.g., neural) to assess team experience (or skill) on another level (e.g., cognitive-behavioral). © 2015, Human Factors and Ergonomics Society.

The EMPOWER project was a collaborative effort to promote a culture of patient safety at Danbury Hospital through an interdisciplinary leadership-driven communication program. The "EMPOWER" component includes Educating and Mentoring Paraprofessionals On Ways to Enhance Reporting of changes in patient status. Specifically, the EMPOWER program was designed to prepare paraprofessional staff (PPS) to communicate changes in patient status using SBAR (situation, background, assessment, recommendations) structured communication. The specific project goals included (a) translation of SBAR structured communication methods for use with PPS, (b) reduction of cultural and educational barriers to interdisciplinary communication, and (c) examination of the effect of the EMPOWER intervention on the PPS communication practices and perceptions of the patient safety culture. Results of the project indicate a change in the use of SBAR throughout the institution, with particular improvement in communication from PPS to professional staff.

You have been framed! How antecedents of information need mediate the effects of risk communication messages.

This study investigates the processes that mediate the effects of framing flood risks on people's information needs. Insight into the effects of risk frames is important for developing balanced risk communication that explains both risks and benefits of living near water. The research was inspired by the risk information seeking and processing model and related models. In a web-based survey, respondents (n = 1,457) were randomly assigned to one of three communication frames or a control frame (experimental conditions). Each frame identically explained flood risk and additionally refined the message by emphasizing climate change, the quality of flood risk management, or the amenities of living near water. We tested the extent to which risk perceptions, trust, and affective responses mediate the framing effects on information need. As expected, the frames on average resulted in higher information need than the control frame. Attempts to lower fear appeal by stressing safety or amenities instead of climate change were marginally successful, a phenomenon that is known as a "negativity bias." Framing effects were mediated by negative attributes (risk perception and negative affect) but not by positive attributes (trust and positive affect). This finding calls for theoretical refinement. Practically, communication messages will be more effective when they stimulate risk perceptions and evoke negative affect. However, arousal of fear may have unwanted side effects. For instance, fear arousal could lead to lower levels of trust in risk management among citizens. Regular monitoring of citizens' attitudes is important to prevent extreme levels of distrust or cynicism. © 2014 Society for Risk Analysis.

Making Climate Hot: Preparing Scientists and Teachers for Climate Change Communication and Education

Anyone having anything to do with climate change science (or even geosciences) is increasingly asked to communicate about climate change with friends and family, media, the general public, and students. But, we have often not had the training to communicate with simplicity and clarity about such a complex topic. Furthermore, the need to know how to accommodate controversy, common misconceptions, and contrarian arguments complicates the task. The CIRES Education and Outreach group has developed a short professional development workshop "Making Climate Hot: How to Communicate Effectively about Climate Change". The goals of the workshop are to make scientists and educators aware of best practices in climate change communications, provide some tools for crafting messages, and allow participants to practice skills in a supportive, low-risk environment. The "Making Climate Hot" workshop has been piloted with scientists and university communicators, teachers and environmental educators and college students anxious to communicate with family and roommates. The most and least effective aspects of the workshop will be described, along with the lessons learned and next steps.

Although the Internet has become an important avenue for disseminating health information, theory-driven strategies for aiding individuals in changing or managing health behaviors are lacking. The eHealth Behavior Management Model combines the Transtheoretical Model, the behavioral intent aspect of the Theory of Planned Behavior, and persuasive communication to assist individuals in negotiating the Web toward stage-specific information. It is here - at the point of stage-specific information - that behavioral intent in moving toward more active stages of change occurs. The eHealth Behavior Management Model is applied in three demonstration projects that focus on behavior management issues: parent-child nutrition education among participants in the U.S. Department of Agriculture Special Supplemental Nutrition Program for Women, Infants and Children; asthma management among university staff and students; and human immunodeficiency virus prevention among South African women. Preliminary results have found the eHealth Behavior Management Model to be promising as a model for Internet-based behavior change programming. Further application and evaluation among other behavior and disease management issues are needed.

Coupled hydrological, ecological, decision and economic models for monetary valuation of riparian ecosystem services

Water is a critical component for sustaining both natural and human systems. Yet the value of water for sustaining ecosystem services is not well quantified in monetary terms. Ideally decisions involving water resource management would include an apples-to-apples comparison of the costs and benefits in dollars of both market and non-market goods and services - human and ecosystem. To quantify the value of non-market ecosystem services, scientifically defensible relationships must be developed that link the effect of a decision (e.g. human growth) to the change in ecosystem attributes from current conditions. It is this linkage that requires the "poly-disciplinary" coupling of knowledge and models from the behavioral, physical, and ecological sciences. In our experience another key component of making this successful linkage is development of a strong poly-disciplinary scientific team that can readily communicate complex disciplinary knowledge to non-specialists outside their own discipline. The time to build such a team that communicates well and has a strong sense of trust should not be underestimated. The research described in the presentation incorporated hydrologic, vegetation, avian, economic, and decision models into an integrated framework to determine the value of changes in ecological systems that result from changes in human water use. We developed a hydro-bio-economic framework for the San Pedro River Region in Arizona that considers groundwater, stream flow, and riparian vegetation, as well as abundance, diversity, and distribution of birds. In addition, we developed a similar framework for the Middle Rio Grande of New Mexico. There are six research components for this project: (1) decision support and scenario specification, (2) regional groundwater model, (3) the riparian vegetation model, (4) the avian model, (5) methods for displaying the information gradients in the valuation survey instruments (Choice Modeling and Contingent Valuation), and (6) the economic framework. Our modeling framework began with the identification of factors that influence spatial and temporal changes in riparian vegetation on the two rivers. The linked modeling framework was then employed for making spatial predictions of the changes in presence of surface water, vegetation change, and avian populations in both river systems. An overview of the overall project will be provided, with lessons learned, and initial valuation survey results.

To explore hospital leaders' perceptions of organisational factors as barriers and/or facilitators in improving inpatient-outpatient (IP-OP) communication. Semistructured in-person interviews. Constant comparative method of qualitative data. Inpatient psychiatry units in 33 general medical/surgical and specialty psychiatric hospitals in California and Massachusetts (USA). Psychiatry chair/chief, service director or medical director. Importance to leadership, resources, organisational structure and culture. A majority of hospital leaders rated the IP-OP communication objective as highly or moderately important. Hospitals with good IP-OP communication had structures in place to support communication or had changed/implemented new procedures to enhance communication, and anticipated clinicians would 'buy in' to the goal of improved communication. Hospitals reporting no improvement efforts were less likely to have structures supporting IP-OP communication, anticipated resistance among clinicians and reported a need for technological resources such as electronic health records, integrated IT and secure online communication. Most leaders reported a need for additional staff time and information, knowledge or data. For many hospitals, successfully improving communication will require overcoming organisational barriers such as cultures not conducive to change and lack of resources and infrastructure. Creating a culture that values communication at discharge may help improve outcomes following hospitalisation, but changes in healthcare delivery in the past few decades may necessitate new strategies or changes at the systems level to address barriers to effective communication.

Differential Equations Models to Study Quorum Sensing.

PubMed

Pérez-Velázquez, Judith; Hense, Burkhard A

2018-01-01

Mathematical models to study quorum sensing (QS) have become an important tool to explore all aspects of this type of bacterial communication. A wide spectrum of mathematical tools and methods such as dynamical systems, stochastics, and spatial models can be employed. In this chapter, we focus on giving an overview of models consisting of differential equations (DE), which can be used to describe changing quantities, for example, the dynamics of one or more signaling molecule in time and space, often in conjunction with bacterial growth dynamics. The chapter is divided into two sections: ordinary differential equations (ODE) and partial differential equations (PDE) models of QS. Rates of change are represented mathematically by derivatives, i.e., in terms of DE. ODE models allow describing changes in one independent variable, for example, time. PDE models can be used to follow changes in more than one independent variable, for example, time and space. Both types of models often consist of systems (i.e., more than one equation) of equations, such as equations for bacterial growth and autoinducer concentration dynamics. Almost from the onset, mathematical modeling of QS using differential equations has been an interdisciplinary endeavor and many of the works we revised here will be placed into their biological context.

Predicting the effect of urban noise on the active space of avian vocal signals.

PubMed

Parris, Kirsten M; McCarthy, Michael A

2013-10-01

Urbanization changes the physical environment of nonhuman species but also markedly changes their acoustic environment. Urban noise interferes with acoustic communication in a range of animals, including birds, with potentially profound impacts on fitness. However, a mechanistic theory to predict which species of birds will be most affected by urban noise is lacking. We develop a mathematical model to predict the decrease in the active space of avian vocal signals after moving from quiet forest habitats to noisy urban habitats. We find that the magnitude of the decrease is largely a function of signal frequency. However, this relationship is not monotonic. A metaregression of observed increases in the frequency of birdsong in urban noise supports the model's predictions for signals with frequencies between 1.5 and 4 kHz. Using results of the metaregression and the model described above, we show that the expected gain in active space following observed frequency shifts is up to 12% and greatest for birds with signals at the lower end of this frequency range. Our generally applicable model, along with three predictions regarding the behavioral and population-level responses of birds to urban noise, represents an important step toward a theory of acoustic communication in urban habitats.

Scientific visualization of glacier changes for public communication: the example of Findelengletscher, Switzerland

NASA Astrophysics Data System (ADS)

Rastner, Philipp; Jörg, Philipp Claudio; Huss, Matthias; Zemp, Michael

2013-04-01

The melting of glaciers and ice caps has been recognized as one of the best natural indicators for global climate change. In Switzerland, the early onset of both glacier research and detailed mapping of the country resulted in a wealth of historical material documenting glacier changes over the past 160 years. Fife years ago, the Universities of Zurich and Fribourg, along with the Swiss energy utility Axpo, launched the Glacier Laserscanning Experiment Obervallis (GLAXPO). In this project three laserscanning flights were performed on Findelengletscher in order to create high resolution Digital Elevation Models (DEM). These DEM provide a precise mapping of the glacier surface topography and serve as reference surface for the co-registration of past DEMs computed from digitized historical maps. In addition to that distributed numerical glacier models were run with ensembles of climate change scenarios in order to calculate glacier changes over the 21st century. The present work makes use of this great data pool for a scientifically correct visualization of 3-dimensional changes of Findelengletscher from AD 1850 to 2100 for public communication. We therefore collected ten different historical maps with the earliest dating from 1862 (plane survey sheet of the Dufour map). The pre-processing included georeferencing and digitalization of contour lines for the creation of different historical DEMs. Afterwards all historical DEMs were co-registered to one of the latest high resolution laserscanning DEM (from 2005). In between years with available DEMs, surface changes were interpolated linearly to create a sequence for the computer animation. For future developments, modeled glacier elevation changes where added/subtracted from the latest DEM (from 2010). Finally, two animations, showing glacier changes from 1850-2010 and 2010-2100, were composed and rendered in the animation program Visual Nature Studio 3. In cooperation with professional booth and model builders, these animations were set up as a glacier exhibit including an interactive touchscreen, a large panoramic view of the Findelen Valley, and an additional interactive monitor providing related background information in French and German. Beginning of 2013, the glacier exhibit was launched as permanent part of the Axporama visitor center and ready for more than 10,000 public visitors a year.

The visual communication of risk.

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

The Hurricane Rainband and Intensity Change Experiment (RAINEX): Observations and Modeling of Hurricanes Katrina, Ophelia, and Rita (2005)

The Hurricane Rainband and Intensity Change Experiment (RAINEX) used three P3 aircraft aided by high- resolution numerical modeling and satellite communications to investigate the 2005 Hurricanes Katrina, Ophelia, and Rita. The aim was to increase the understanding of tropical cyclone intensity change by interactions between a tropical cyclone's inner core and rainbands. All three aircraft had dual-Doppler radars, with the ELDORA radar on board the Naval Research Laboratory's P3 aircraft, providing particularly detailed Doppler radar data. Numerical model forecasts helped plan the aircraft missions, and innovative communications and data transfer in real time allowed the flights to be coordinated from a ground-based operations center. The P3 aircraft released approximately 600 dropsondes in locations targeted for optimal coordination with the Doppler radar data, as guided by the operations center. The storms were observed in all stages of development, from Tropical Depression to Category 5 hurricane. The data from RAINEX are readily available through an online Field Catalog and RAINEX Data Archive. The RAINEX dataset is illustrated by a preliminary analysis of Hurricane Rita, which was documented by multi-aircraft flights on five days: 1) while a tropical storm, 2) while rapidly intensifying to a Category 5 hurricane, 3) during an eyewall replacement, 4) when the hurricane became asymmetric upon encountering environmental shear, and 5) just prior to landfall.

Put a Frame on It: Contextualizing Climate Change for Museum Visitors

NASA Astrophysics Data System (ADS)

Canning, Katharine

Public opinion polls continue to show that Americans are divided---particularly along political and ideological lines---on whether climate change is real and warrants immediate action. Those in the natural and social sciences have recognized that effective communication is key to closing the gap that exists between scientific and public understanding on this issue. A body of social science research on climate change communication has emerged within the last decade. This field has identified strategies for climate change communicators and educators, emphasizing the importance of framing climate change issues in ways that help it resonate with a wider range of public concerns and values in order to develop a shared belief regarding the necessity of action. Museum exhibits and programs on climate change that were developed within the last five years are likely to have benefitted from this body of work. This qualitative research seeks to examine and analyze the various ways museums in the United States are communicating about climate change related issues to the public. Three case studies of museum exhibits on climate change issues were examined. The scope and purpose of climate change communication in museums, the specific messages that museums are choosing to communicate, and how those messages are being framed for public audiences were explored through these case studies. The findings suggest that museums are considering their audience when framing messages about climate change and have used work from the climate change communication field to inform message development. In particular, museums are making climate change issues more relevant by emphasizing social, economic, and human health concerns, and are considering strategies to counteract fear-fatigue and empower visitors to take action.

Despite the expansion of early intervention approaches for young children with ASD, investigators have struggled to identify measures capable of assessing social communication change in response to these interventions. Addressing recent calls for efficient, sensitive, and reliable social communication measures, the current paper outlines the refinement and validation of the Social Communication Checklist (SCC). We discuss two small studies exploring the psychometric properties of the SCC and the SCC-R (revised Social Communication Checklist), including sensitivity to change, inter-rater reliability, and test-retest reliability, in two samples of children with ASD and one sample of typically-developing children. Results indicate this measure is reliable, sensitive to change after a brief social communication intervention, and strongly related to well-established measures of social communicative functioning.

Personal models of diabetes comprise beliefs about symptoms, treatment effectiveness, consequences and emotional responses to possible future complications. They are associated with, and influence, self-care behaviour. Little work has examined potential influences on the development and maintenance of personal models. The aims of this study were: (i) to assess changes in personal models over 2 years from diagnosis of diabetes; and (ii) to examine the relative contributions of health threat communication (at diagnosis, since diagnosis, during follow-up care) and personality to personal models of diabetes 2 years post-diagnosis. Newly diagnosed patients were interviewed at diagnosis (< 3 months; time 1) and 6 months (time 2), 1 year (time 3) and 2 years (time 4) after diagnosis. Data were available for 158 patients at time 1 (32 Type 1 patients and 126 Type 2 patients), 147 at time 2, 142 at time 3 and 138 at time 4. Perceptions of symptoms, consequences, course and control of diabetes remained stable over time. Emotional responses decreased and illness coherence (perceived understanding) increased over time. Health threat communication was a stronger predictor of personal models than personality. Emotional responses to diabetes 2 years after diagnosis were predicted by perceptions of a threatening health message (at diagnosis 18%, at follow-up 5%). Health threat communication predicted perceptions of serious consequences (at diagnosis 5%, at follow-up 9%). Perceptions of a reassuring message during follow-up were related to beliefs of treatment effectiveness (26%). The communication of information and the way it is perceived is an important determinant of the patient's view of their diabetes. The initial effects of the education process at diagnosis persisted 2 years after diagnosis.

The nature of the (visualization) game: Challenges and opportunities from computational geophysics

NASA Astrophysics Data System (ADS)

Kellogg, L. H.

As the geosciences enters the era of big data, modeling and visualization become increasingly vital tools for discovery, understanding, education, and communication. Here, we focus on modeling and visualization of the structure and dynamics of the Earth's surface and interior. The past decade has seen accelerated data acquisition, including higher resolution imaging and modeling of Earth's deep interior, complex models of geodynamics, and high resolution topographic imaging of the changing surface, with an associated acceleration of computational modeling through better scientific software, increased computing capability, and the use of innovative methods of scientific visualization. The role of modeling is to describe a system, answer scientific questions, and test hypotheses; the term "model" encompasses mathematical models, computational models, physical models, conceptual models, statistical models, and visual models of a structure or process. These different uses of the term require thoughtful communication to avoid confusion. Scientific visualization is integral to every aspect of modeling. Not merely a means of communicating results, the best uses of visualization enable scientists to interact with their data, revealing the characteristics of the data and models to enable better interpretation and inform the direction of future investigation. Innovative immersive technologies like virtual reality, augmented reality, and remote collaboration techniques, are being adapted more widely and are a magnet for students. Time-varying or transient phenomena are especially challenging to model and to visualize; researchers and students may need to investigate the role of initial conditions in driving phenomena, while nonlinearities in the governing equations of many Earth systems make the computations and resulting visualization especially challenging. Training students how to use, design, build, and interpret scientific modeling and visualization tools prepares them to better understand the nature of complex, multiscale geoscience data.

Challenges of Communicating Climate Change in North Dakota: Undergraduate Internship and Collaboration with Middle School Educators

Mullendore, G. L.; Munski, L.; Kirilenko, A.; Remer, F.; Baker, M.

2012-12-01

In summer 2010, the University of North Dakota (UND) hosted an internship for undergraduates to learn about climate change in both the classroom and group research projects. As a final project, the undergraduates were tasked to present their findings about different aspects of climate change in webcasts that would be later used in middle school classrooms in the region. Interns indicated that participation significantly improved their own confidence in future scholarly pursuits. Also, communicating about climate change, both during the project and afterwards, helped the interns feel more confident in their own learning. Use of webcasts widened the impact of student projects (e.g. YouTube dissemination), and multiple methods of student communication should continue to be an important piece of climate change education initiatives. Other key aspects of the internship were student journaling and group building. Challenges faced included media accessibility and diverse recruiting. Best practices from the UND internship will be discussed as a model for implementation at other universities. Lesson plans that complement the student-produced webcasts and adhere to regional and national standards were created during 2011. Communication between scientists and K-12 education researchers was found to be a challenge, but improved over the course of the project. These lesson plans have been reviewed both during a teacher workshop in January 2012 and by several Master teachers. Although select middle school educators have expressed enthusiasm for testing of these modules, very little hands-on testing with students has occurred. Wide-ranging roadblocks to implementation exist, including the need for adherence to state standards and texts, inadequate access to technology, and generally negative attitudes toward climate change in the region. Feedback from regional educators will be presented, and possible solutions will be discussed. Although some challenges are specific to the Northern Great Plains region, understanding these challenges are important for agencies and universities with goals of national dissemination.

Uncertainty As a Trigger for a Paradigm Change in Science Communication

NASA Astrophysics Data System (ADS)

Schneider, S.

2014-12-01

Over the last decade, the need to communicate uncertainty increased. Climate sciences and environmental sciences have faced massive propaganda campaigns by global industry and astroturf organizations. These organizations use the deep societal mistrust in uncertainty to point out alleged unethical and intentional delusion of decision makers and the public by scientists and their consultatory function. Scientists, who openly communicate uncertainty of climate model calculations, earthquake occurrence frequencies, or possible side effects of genetic manipulated semen have to face massive campaigns against their research, and sometimes against their person and live as well. Hence, new strategies to communicate uncertainty have to face the societal roots of the misunderstanding of the concept of uncertainty itself. Evolutionary biology has shown, that human mind is well suited for practical decision making by its sensory structures. Therefore, many of the irrational concepts about uncertainty are mitigated if data is presented in formats the brain is adapted to understand. At the end, the impact of uncertainty to the decision-making process is finally dominantly driven by preconceptions about terms such as uncertainty, vagueness or probabilities. Parallel to the increasing role of scientific uncertainty in strategic communication, science communicators for example at the Research and Development Program GEOTECHNOLOGIEN developed a number of techniques to master the challenge of putting uncertainty in the focus. By raising the awareness of scientific uncertainty as a driving force for scientific development and evolution, the public perspective on uncertainty is changing. While first steps to implement this process are under way, the value of uncertainty still is underestimated in the public and in politics. Therefore, science communicators are in need for new and innovative ways to talk about scientific uncertainty.

Recognizing the importance of conversation between experts and non-experts in science communication

Science communication is often perceived by scientists as the flow of information from experts to non-experts, and institutions have responded by providing science communication training that focuses on best practices for disseminating information. This unidirectional approach neglects a key component of science communication: scientists must understand the needs and values of the stakeholders for whom they are producing information, whether the stakeholders are community members, resource managers, or policy makers. We designed an activity for graduate students enrolled in a science communication class at the McCall Outdoor Science School to both alert them to this misconception, and to give them an opportunity to rectify it. Over the course of 24-hours, we challenged students to have a conversation about climate change with someone they encountered in the community of McCall, ID. Using material from their conversations, students created a story in podcast or video form to share with the class. Through reflecting on this activity, students experienced a change in their perceptions of their identities as science communicators. Many students expressed an increased interest in listening to the stories of community members to learn more about the community's needs and values. We repeated the activity with early career scientists attending a climate workshop in McCall offered by the USGS Northwest Climate Science Center, focusing our evaluation around the science identity model of Carlone and Johnson (2007). Evaluations suggest that participants recognized their role as scientists in not only to providing information, but also in listening to the values and needs of the people for whom they are working. We believe this understanding is fundamental to being a good science communicator and ensuring that science remains relevant to communities.

Developing and Optimising the Use of Logic Models in Systematic Reviews: Exploring Practice and Good Practice in the Use of Programme Theory in Reviews.

PubMed

Kneale, Dylan; Thomas, James; Harris, Katherine

2015-01-01

Logic models are becoming an increasingly common feature of systematic reviews, as is the use of programme theory more generally in systematic reviewing. Logic models offer a framework to help reviewers to 'think' conceptually at various points during the review, and can be a useful tool in defining study inclusion and exclusion criteria, guiding the search strategy, identifying relevant outcomes, identifying mediating and moderating factors, and communicating review findings. In this paper we critique the use of logic models in systematic reviews and protocols drawn from two databases representing reviews of health interventions and international development interventions. Programme theory featured only in a minority of the reviews and protocols included. Despite drawing from different disciplinary traditions, reviews and protocols from both sources shared several limitations in their use of logic models and theories of change, and these were used almost unanimously to solely depict pictorially the way in which the intervention worked. Logic models and theories of change were consequently rarely used to communicate the findings of the review. Logic models have the potential to be an aid integral throughout the systematic reviewing process. The absence of good practice around their use and development may be one reason for the apparent limited utility of logic models in many existing systematic reviews. These concerns are addressed in the second half of this paper, where we offer a set of principles in the use of logic models and an example of how we constructed a logic model for a review of school-based asthma interventions.

Climate change risk perception and communication: addressing a critical moment?

Pidgeon, Nick

2012-06-01

Climate change is an increasingly salient issue for societies and policy-makers worldwide. It now raises fundamental interdisciplinary issues of risk and uncertainty analysis and communication. The growing scientific consensus over the anthropogenic causes of climate change appears to sit at odds with the increasing use of risk discourses in policy: for example, to aid in climate adaptation decision making. All of this points to a need for a fundamental revision of our conceptualization of what it is to do climate risk communication. This Special Collection comprises seven papers stimulated by a workshop on "Climate Risk Perceptions and Communication" held at Cumberland Lodge Windsor in 2010. Topics addressed include climate uncertainties, images and the media, communication and public engagement, uncertainty transfer in climate communication, the role of emotions, localization of hazard impacts, and longitudinal analyses of climate perceptions. Climate change risk perceptions and communication work is critical for future climate policy and decisions. © 2012 Society for Risk Analysis.

Appropriate and effective communication is central to the success of interventions to reduce the risk of HIV infection. This paper reviews what has been learned about the nature of communication in the behavior change process. It examines the contexts in which communication occurs, as well as the contribution of communication theory, social marketing theory, and structural intervention theory to intervention development. Guidance is offered on the most appropriate ways in which to communicate with different groups and audiences, and future priorities for research and intervention are identified.

Ineffective communication among members of a multidisciplinary team is associated with operative error and failure to rescue. We sought to measure operative team communication in a simulated emergency using an established communication framework called "closed loop communication." We hypothesized that communication directed at a specific recipient would be more likely to elicit a check back or closed loop response and that this relationship would vary with changes in patients' clinical status. We used the closed loop communication framework to code retrospectively the communication behavior of 7 operative teams (each comprising 2 surgeons, anesthesiologists, and nurses) during response to a simulated, postanesthesia care unit "code blue." We identified call outs, check backs, and closed loop episodes and applied descriptive statistics and a mixed-effects negative binomial regression to describe characteristics of communication in individuals and in different specialties. We coded a total of 662 call outs. The frequency and type of initiation and receipt of communication events varied between clinical specialties (P < .001). Surgeons and nurses initiated fewer and received more communication events than anesthesiologists. For the average participant, directed communication increased the likelihood of check back by at least 50% (P = .021) in periods preceding acute changes in the clinical setting, and exerted no significant effect in periods after acute changes in the clinical situation. Communication patterns vary by specialty during a simulated operative emergency, and the effect of directed communication in eliciting a response depends on the clinical status of the patient. Operative training programs should emphasize the importance of quality communication in the period immediately after an acute change in the clinical setting of a patient and recognize that communication patterns and needs vary between members of multidisciplinary operative teams.

Wiig, E H

1991-01-01

We are beginning a decade, during which many traditional paradigms in education, special education, and speech-language pathology will undergo change. Among paradigms considered promising for speech-language pathology in the schools are collaborative language intervention and strategy training for language and communication. This presentation introduces management models for developing a collaborative language intervention process, among them the Deming Management Method for Total Quality (TQ) (Deming 1986). Implementation models for language assessment and IEP planning and multicultural issues are also introduced (Damico and Nye 1990; Secord and Wiig in press). While attention to processes involved in developing and implementing collaborative language intervention is paramount, content should not be neglected. To this end, strategy training for language and communication is introduced as a viable paradigm. Macro- and micro-level process models for strategy training are featured and general issues are discussed (Ellis, Deshler, and Schumaker 1989; Swanson 1989; Wiig 1989).

Effect of community based behavioural change communication intervention to improve neonatal mortality in developing countries: A Systematic Review.

PubMed

Tilahun, Dejene; Birhanu, Zewdie

2011-01-01

Background A great burden of infant and under-five childhood mortality occurs during the neonatal period, usually within a few days of birth. Community based behavioural change communication (such as interpersonal, group and mass media channels, including participatory methods at community level) intervention trials have been shown to be effective in reducing this mortality. However, to guide policy makers and programme planners, there is a need to systematically appraise and synthesise this evidence.Objective To systematically search, appraise and synthesise the best available evidence on the effect of community based behavioural change communication intervention to improve neonatal mortality in developing countries.Inclusion Criteria This review considered randomised controlled community trials on the effectiveness of community based behavioural change communication interventions aimed at decreasing neonatal mortality that were conducted in developing countries.Search Strategy This review considered English language articles on studies published between December, 2006 to January, 2011 and indexed in PubMed, CINAHL, EMBASE, Mednar, popline, Proquest, or Hinari.Methodological quality Studies that met the inclusion criteria were assessed for methodological quality using the Joanna Briggs Institute Meta Analysis of Statistical Assessment and Review Instrument by two independent reviewers. Data were analysed using a fixed effects model with RevMan5 software. Community based behavioural change communication interventions were found to be associated with a significant reduction in neonatal mortality of 19% (average OR 0.81; 95%CI 0. to 0.88), early neonatal mortality by 20% (average 0.80; 95%CI 0. to 0.91), late neonatal mortality by 21% (average 0.79; 95%CI 0. to 0.99). In addition, the intervention also resulted in significant improvement of newborn care practice; breast feeding initiation, clean cord cutting and delay in bathing were improved by 185%, 110% and 196% respectively.Conclusions Community-based behavioural change communication interventions such as health education, information education and communication, behavioural change communication, social mobilisation, community mobilisation, community conversation, and home based counselling were found to be associated with a significant reduction in neonatal mortality, early neonatal mortality and post neonatal mortality. The findings of this systematic review call for integration of such interventions into conventional strategies in developing countries.Implications for practice This systematic review has shown that community based behavioural change communication interventions that are implemented through community health volunteers and other community based health workers, targeted at pregnant women and also involving influential people such as mothers-in-law, fathers-in-law and husbands/partners, consistently demonstrated that community based intervention packages significantly reduced early neonatal, late neonatal and neonatal mortality rates and also have a pivotal role in improving household newborn care practice. Thus, this review provides encouraging evidence of the value of integrating newborn care and neonatal mortality reduction strategies into community based approaches.Implications for research The review findings were largely derived from a limited number of community trials from developing regions, particularly the African setting. Thus, there is a clear need for additional research on a larger scale and in more varied settings. There is also a need for more evidence based on higher quality research. The cost effectiveness of these community based interventions may impact on their adoption; however it was outside the scope of this review. Cost-effectiveness of these interventions should become a priority area for future research.

Does the Brief Observation of Social Communication Change help moving forward in measuring change in early autism intervention studies?

The field of early autism research is in dire need of outcome measures that adequately reflect subtle changes in core autistic behaviors. This article compares the ability of a newly developed measure, the Brief Observation of Social Communication Change (BOSCC), and the Autism Diagnostic Observation Schedule (ADOS) to detect changes in core symptoms of autism in 44 toddlers. The results provide encouraging evidence for the Brief Observation of Social Communication Change as a candidate outcome measure, as reflected in sufficient inter- and intra-rater reliability, independency from other child characteristics, and sensitivity to capture change. Although the Brief Observation of Social Communication Change did not evidently outperform the Autism Diagnostic Observation Schedule on any of these quality criteria, the instrument may be better able to capture subtle, individual changes in core autistic symptoms. The promising findings warrant further study of this new instrument.

Hemispherical optical dome for underwater communication

For many years, acoustic systems have been used as the primary method for underwater communication; however, the data transfer rate of such systems is low because sound propagates slowly through water. A higher throughput can be achieved using visible light to transmit data underwater. The first issue with this approach is that there is generally a large loss of the light signal due to scattering and absorption in water, even though there is an optimal wavelength for transmission in the blue or green wavelengths of the visible spectrum. The second issue is that a simple communication system, consisting only of a highly directional source/transmitter and small optical detector/receiver, has a very narrow field of view. The goal of this project is to improve an optical, underwater communication system by increasing the effective field of view of the receiving optics. To this end, we make two changes to the simple system: (1) An optical dome was added near the receiver. An array of lenses is placed radially on the surface of the dome, reminiscent of the compound eye of an insect. The lenses make the source and detector planes conjugate, and each lens adds a new region of the source plane to the instrument's total field of view. (2) The receiver was expanded to include multiple photodiodes. With these two changes, the receiver has much more tolerance to misalignments (in position and angle) of the transmitter. Two versions of the optical dome (with 6" and 8" diameters) were designed using PTC's Creo CAD software and modeled using Synopsys' CODE V optical design software. A series of these transparent hemispherical domes, with both design diameters, were manufactured using a 5-axis mill. The prototype was then retrofitted with lenses and compared with the computer-generated model to demonstrate the effectiveness of this solution. This work shows that the dome design improves the optical field of view of the underwater communication system considerably. Furthermore, with the experimental test results, a geometric optimization model was derived providing insights to the design performance limits.

The increasing extent and vulnerability of technologically advanced society together with aspects of global climate change intensifies the frequency and severity of natural disasters. Every year, communities around the world face the devastating consequences of hazardous events, including loss of life, property and infrastructure damage, and environmental decline. In this session, we will introduce a new book, entitled New Trends in Communicating Risk and Cultivating Resilience, which is dedicated to those who have directly or indirectly suffered the effects of climate change extreme events with the hope that the advance of knowledge, implementation of sound science and appropriate policies, and use of effective communication will help in reducing their vulnerability while also improving resilience in the face of often devastating natural hazards. This book comprises manuscripts from those whose research, advocacy, work, teaching, or service in the natural or social sciences deals with risk communication and/or management surrounding natural disasters, with a particular focus on climate change-related phenomena. This book is arranged into five sections: The Role of Communication in Fostering Resilient Communities (Reframing the conversation about natural hazards and climate change with a new focus on resilience)Before the Disaster: Prediction, Preparation, and Crisis Communication (The role of communication in predicting and preparing for the unpredictable regarding natural disasters)Mitigating Circumstances: Living Through Change, Uncertainty, and Disaster (Mitigation and the role of communication in minimizing the damage during natural disasters and during an era of climate change)After the Disaster: Response and Recovery Communication (The role of communication after natural disasters)Looking Back and Learning Forward: Best and Worst Practices Exposed (Considering risk and resilience communication of natural disasters with one eye on best practices and one eye on a critical perspective. Case studies of resilience both supported and undermined by communication)During our presentation, we will introduce a case study from every section.

The strong scientific consensus about the reality and risks of anthropogenic climate change stands in stark contrast to widespread confusion and complacency among the public. Many efforts to close that gap, grounded in the information deficit model of risk communication, provide scientific information on climate change through reports and presentations. However, research shows that showing people research does not work: the gap between scientific and public understanding of climate change remains wide. Tools that are rigorously grounded in the science and motivate action on climate change are urgently needed. Here we assess the impact of one such tool, an interactive, role-play simulation, World Climate. Participants take the roles of delegates to the UN climate negotiations and are challenged to create an agreement limiting warming to no more than 2°C. The C-ROADS climate simulation model then provides participants with immediate feedback about the expected impacts of their decisions. Participants use C-ROADS to explore the climate system and use the results to refine their negotiating positions, learning about climate change while experiencing the social dynamics of negotiations and decision-making. Pre- and post-survey results from 21 sessions in eight nations showed significant gains in participants' climate change knowledge, affective engagement, intent to take action, and desire to learn. Contrary to the deficit model, gains in participants' desire to learn more and intention to act were associated with gains in affective engagement, particularly feelings of urgency and hope, but not climate knowledge. Gains were just as strong among participants who oppose government regulation, suggesting the simulation's potential to reach across political divides. Results indicate that simulations like World Climate offer a climate change communication tool that enables people to learn and feel for themselves, which together have the potential to motivate action informed by science.

The HEALTHY Study was a 3-year school-based intervention designed to change the behaviors of middle school students to reduce their risk for developing type 2 diabetes mellitus. This report examines the relation between exposure to communications campaign materials and behavior change among students in the HEALTHY intervention schools. Using data from campaign tracking logs and student interviews, the authors examined communications campaign implementation and exposure to the communications campaign as well as health behavior change. Campaign tracking documents revealed variability across schools in the quantity of communications materials disseminated. Student interviews confirmed that there was variability in the proportion of students who reported receiving information from the communication campaign elements. Correlations and regression analysis controlling for semester examined the association between campaign exposure and behavior change across schools. There was a significant association between the proportion of students exposed to the campaign and the proportion of students who made changes in health behavior commensurate with study goals. The results suggest that, in the context of a multifaceted school-based health promotion intervention, schools that achieve a higher rate of exposure to communication campaign materials among the students may stimulate greater health behavior change.

Guarascio-Howard, Linda

2011-01-01

A medical-surgical unit in a southwestern United States hospital examined the results of adding wireless communication technology to assist nurses in identifying patient bed status changes and enhancing team communication. Following the addition of wireless communication, response time to patient calls and the number of nurse-initiated communications were compared to pre-wireless calls and response time sampling period. In the baseline study, nurse-initiated communications and response time to patient calls were investigated for a team nursing model (Guarascio-Howard & Malloch, 2007). At this time, technology consisted of a nurse call system and telephones located at each decentralized nurse station and health unit coordinator (HUC) station. For this follow-up study, a wireless device was given to nurses and their team members following training on device use and privacy issues. Four registered nurses (RNs) were shadowed for 8 hours (32 hours total) before and after the introduction of the wireless devices. Data were collected regarding patient room visits, number of patient calls, bed status calls, response time to calls, and the initiator of the communication episodes. Follow-up study response time to calls significantly decreased (t-test p = .03). RNs and licensed practical nurses responded to bed status calls in less than 1 minute-62% of the 37 calls. Communication results indicated a significant shift (One Proportion Z Test) in RN-initiated communications, suggesting an enhanced ability to communicate with team members and to assist in monitoring patient status. Patient falls trended downward, although not significantly (p > .05), for a 6-month period of wireless technology use compared to the same period the previous year. The addition of a wireless device has advantages in team nursing, namely increasing communication with staff members and decreasing response time to patient and bed status calls. Limitations of the study included a change in caregiver team members and issues regarding wireless device and locator badge compliance. Administrative issues that arose during this field study included bed and cable maintenance, device battery charging, and the training of new and floating team members.

The new medical device communication protocol known as IEEE 11073 SDC is well-suited for the integration of (surgical) point-of-care devices, so are the established Health Level Seven (HL7) V2 and Digital Imaging and Communications in Medicine (DICOM) standards for the communication of systems in the clinical IT infrastructure (CITI). An integrated operating room (OR) and other integrated clinical environments, however, need interoperability between both domains to fully unfold their potential for improving the quality of care as well as clinical workflows. This work thus presents concepts for the propagation of clinical and administrative data to medical devices, physiologic measurements and device parameters to clinical IT systems, as well as image and multimedia content in both directions. Prototypical implementations of the derived components have proven to integrate well with systems of networked medical devices and with the CITI, effectively connecting these heterogeneous domains. Our qualitative evaluation indicates that the interoperability concepts are suitable to be integrated into clinical workflows and are expected to benefit patients and clinicians alike. The upcoming HL7 Fast Healthcare Interoperability Resources (FHIR) communication standard will likely change the domain of clinical IT significantly. A straightforward mapping to its resource model thus ensures the tenability of these concepts despite a foreseeable change in demand and requirements.

Volatile communication in plant-aphid interactions.

PubMed

de Vos, Martin; Jander, Georg

2010-08-01

Volatile communication plays an important role in mediating the interactions between plants, aphids, and other organisms in the environment. In response to aphid infestation, many plants initiate indirect defenses through the release of volatiles that attract ladybugs, parasitoid wasps, and other aphid-consuming predators. Aphid-induced volatile release in the model plant Arabidopsis thaliana requires the jasmonate signaling pathway. Volatile release is also induced by infection with aphid-transmitted viruses. Consistent with mathematical models of optimal transmission, viruses that are acquired rapidly by aphids induce volatile release to attract migratory aphids, but discourage long-term aphid feeding. Although the ecology of these interactions is well-studied, further research is needed to identify the molecular basis of aphid-induced and virus-induced changes in plant volatile release.

Performance analysis of wideband data and television channels. [space shuttle communications

Several aspects are discussed of space shuttle communications, including the return link (shuttle-to-ground) relayed through a satellite repeater (TDRS). The repeater exhibits nonlinear amplification and an amplitude-dependent phase shift. Models were developed for various link configurations, and computer simulation programs based on these models are described. Certain analytical results on system performance were also obtained. For the system parameters assumed, the results indicate approximately 1 db degradation relative to a link employing a linear repeater. While this degradation is dependent upon the repeater, filter bandwidths, and modulation parameters used, the programs can accommodate changes to any of these quantities. Thus the programs can be applied to determine the performance with any given set of parameters, or used as an aid in link design.

High Reliability Organizations--Medication Safety.

PubMed

Yip, Luke; Farmer, Brenna

2015-06-01

High reliability organizations (HROs), such as the aviation industry, successfully engage in high-risk endeavors and have low incidence of adverse events. HROs have a preoccupation with failure and errors. They analyze each event to effect system wide change in an attempt to mitigate the occurrence of similar errors. The healthcare industry can adapt HRO practices, specifically with regard to teamwork and communication. Crew resource management concepts can be adapted to healthcare with the use of certain tools such as checklists and the sterile cockpit to reduce medication errors. HROs also use The Swiss Cheese Model to evaluate risk and look for vulnerabilities in multiple protective barriers, instead of focusing on one failure. This model can be used in medication safety to evaluate medication management in addition to using the teamwork and communication tools of HROs.

What Type of Communication during Conflict is Beneficial for Intimate Relationships?

PubMed Central

Overall, Nickola C.; McNulty, James K.

2016-01-01

What constitutes effective communication during conflict? Answering this question requires (a) clarifying whether communication expresses opposition versus cooperation and is direct versus indirect, (b) assessing the mechanisms through which communication effects relationships, and (c) identifying the contextual factors that determine the impact of communication. Recent research incorporating these components illustrates that direct opposition is beneficial when serious problems need to be addressed and partners are able to change, but can be harmful when partners are not confident or secure enough to be responsive. In contrast, cooperative communication involving affection and validation can be harmful when serious problems need to changed, but may be beneficial when problems are minor, cannot be changed, or involve partners whose defensiveness curtails problem solving.

Research indicates that the public views zoos and aquariums as reliable and trusted sources for information on conservation. Additionally, visiting zoos and aquariums helps people reconsider their connections to conservation issues and solutions. The Aquarium of the Pacific, an AZA-accredited institution that serves the most ethnically diverse population of all aquariums in the nation, is using exhibit space, technology, public programming, and staff professional development to present a model for how aquariums can promote climate literacy. Our newest galleries and programs are designed to immerse our visitors in experiences that connect our live animal collection to larger themes on ocean change. The Aquarium is supporting our new programming with a multifaceted staff professional development that exposes our interpretive staff to current climate science and researchers as well as current social science on public perception of climate science. Our staff also leads workshops for scientists; these sessions allow us to examine learning theory and develop tools to communicate science and controversial subjects effectively. Through our partnerships in the science, social science, and informal science education communities, we are working to innovate and develop best practices in climate communication.

Making Electronic Health Records (EHRs) Work: Informal Talk and Workarounds in Healthcare Organizations.

Barrett, Ashley K; Stephens, Keri K

2017-08-01

A key provision of the American Recovery and Reinvestment Act of 2009 mandated that electronic health records (EHR) be adopted in US healthcare organizations by 2015. The purpose of this study is to examine the communicative processes involved as healthcare workers implement an EHR and make changes, known as workarounds. Guided by theories in social influence, and diffusion of innovations, we conducted a survey of healthcare professionals using an EHR system in an organization. Our structural equation modeling (SEM) and multiple regression results reveal coworker communication, in the form of informal social support and feedback, play an important role in whether people engage in workarounds. Understanding this relationship is important because our study also demonstrates that workarounds predict healthcare employees' overall satisfaction with the EHR system. Specifically, workarounds are associated with higher perceptions of the EHR's relative advantage, higher perceptions of EHR implementation success, and lower levels of resistance to EHR change. This study offers a health communication contribution to the growing research on EHR systems and demonstrates the persuasive effects that coworkers have on new technology use in healthcare organizations.

Collective iteration behavior for online social networks

2018-06-01

Understanding the patterns of collective behavior in online social network (OSNs) is critical to expanding the knowledge of human behavior and tie relationship. In this paper, we investigate a specific pattern called social signature in Facebook and Wiki users' online communication behaviors, capturing the distribution of frequency of interactions between different alters over time in the ego network. The empirical results show that there are robust social signatures of interactions no matter how friends change over time, which indicates that a stable commutation pattern exists in online communication. By comparing a random null model, we find the that commutation pattern is heterogeneous between ego and alters. Furthermore, in order to regenerate the pattern of the social signature, we present a preferential interaction model, which assumes that new users intend to look for the old users with strong ties while old users have tendency to interact with new friends. The experimental results show that the presented model can reproduce the heterogeneity of social signature by adjusting 2 parameters, the number of communicating targets m and the max number of interactions n, for Facebook users, m = n = 5, for Wiki users, m = 2 and n = 8. This work helps in deeply understanding the regularity of social signature.

Participation in the UK Newborn Bloodspot Screening Programme (NBSP) requires parental consent but concerns exist about whether or not this happens in practice and the best methods and timing to obtain consent at reasonable cost. To collate all possible modes of prescreening communication and consent for newborn (neonatal) screening (NBS); examine midwives', screening professionals' and users' views about the feasibility, efficiency and impact on understanding of each; measure midwives' and parents' preferences for information provision; and identify key drivers of cost-effectiveness for alternative modes of information provision. Six study designs were used: (1) realist review - to generate alternative communication and consent models; (2) qualitative interviews with parents and health professionals - to examine the implications of current practice for understanding and views on alternative models; (3) survey and observation of midwives - to establish current costs; (4) stated preference surveys with midwives, parents and potential future parents - to establish preferences for information provision; (5) economic analysis - to identify cost-effectiveness drivers of alternative models; and (6) stakeholder validation focus groups and interviews - to examine the acceptability, views and broader impact of alternative communication and consent models. Providers and users of NBS in England. Study 2: 45 parents and 37 health professionals; study 3: 22 midwives and eight observations; study 4: 705 adults aged 18-45 years and 134 midwives; and study 6: 12 health-care professionals and five parents. The realist review identified low parental knowledge and evidence of coercive consent practices. Interview, focus group and stated preference data suggested a preference for full information, with some valuing this more than choice. Health professionals preferred informed choice models but parents and health professionals queried whether or not current consent was fully informed. Barriers to using leaflets effectively were highlighted. All studies indicated that a 'personalised' approach to NBS communication, allowing parents to select the mode and level of information suited to their learning needs, could have added value. A personalised approach should rely on midwife communication and should occur in the third trimester. Overall awareness was identified as requiring improvement. Starting NBS communication by alerting parents that they have a choice to make and telling them that samples could be stored are both likely to enhance engagement. The methods of information provision and maternal anxiety causing additional visits to health-care professionals were the drivers of relative cost-effectiveness. Lack of data to populate an economic analysis, confirmed by value of information analysis, indicated a need for further research. There are some limitations with regard to the range of participants used in studies 2 and 3 and so caution should be exercised when interpreting some of the results. This project highlighted the importance of focusing on information receipt and identified key communication barriers. Health professionals strongly preferred informed consent, which parents endorsed if they were made aware of sample storage. Uniform models of information provision were perceived as ineffective. A choice of information provision was supported by health professionals and parents, which both enhances cost-effectiveness and improves engagement, understanding and the validity of consent. Remaining uncertainties suggest that more research is needed before new communication modes are introduced into practice. Future research should measure the impact of the suggested practice changes (informing in third trimester, information toolkits, changed role of midwife). Current Controlled Trials ISRCTN70227207. This project was funded by the NIHR Health Technology Assessment programme and will be published in full in Health Technology Assessment ; Vol. 21, No. 55.

Purpose, Processes, Partnerships, and Products: 4Ps to advance Participatory Socio-Environmental Modeling

Gray, S. G.; Voinov, A. A.; Jordan, R.; Paolisso, M.

2016-12-01

Model-based reasoning is a basic part of human understanding, decision-making, and communication. Including stakeholders in environmental model building and analysis is an increasingly popular approach to understanding environmental change since stakeholders often hold valuable knowledge about socio-environmental dynamics and since collaborative forms of modeling produce important boundary objects used to collectively reason about environmental problems. Although the number of participatory modeling (PM) case studies and the number of researchers adopting these approaches has grown in recent years, the lack of standardized reporting and limited reproducibility have prevented PM's establishment and advancement as a cohesive field of study. We suggest a four dimensional framework that includes reporting on dimensions of: (1) the Purpose for selecting a PM approach (the why); (2) the Process by which the public was involved in model building or evaluation (the how); (3) the Partnerships formed (the who); and (4) the Products that resulted from these efforts (the what). We highlight four case studies that use common PM software-based approaches (fuzzy cognitive mapping, agent-based modeling, system dynamics, and participatory geospatial modeling) to understand human-environment interactions and the consequences of environmental changes, including bushmeat hunting in Tanzania and Cameroon, agricultural production and deforestation in Zambia, and groundwater management in India. We demonstrate how standardizing communication about PM case studies can lead to innovation and new insights about model-based reasoning in support of environmental policy development. We suggest that our 4P framework and reporting approach provides a way for new hypotheses to be identified and tested in the growing field of PM.

Self-care is a crucial component of diabetes management. But comprehensive behavior change frameworks are needed to provide guidance for the design, implementation, and evaluation of diabetes self-care programs in diverse populations. We tested the Information-Motivation-Behavioral Skills (IMB) model in a sample of Chinese adults with Type 2 diabetes. A cross-sectional study of 222 Chinese adults with type 2 diabetes was conducted in a primary care center. We collected information on demographics, provider-patient communication (knowledge), social support (motivation), self-efficacy (behavioral skills), and diabetes self-care (behavior). The values of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) were also obtained. Measured variable path analyses were used to the IMB framework. Provider-patient communication (β = 0.12, p = .037), and social support (β = 0.19, p = .007) and self-efficacy (β = 0.41, p < .001) were independent, direct predictors of diabetes self-care behavior. Diabetes self-care behaviors had a direct effect on TC/HDL-C (β = -0.31, p < .001) and LDL-C/HDL-C (β = -0.30, p < .001). Consistent with the IMB model, having better provider-patient communication, having social support, and having higher self-efficacy was associated with performing diabetes self-care behaviors; and these behaviors were directly linked to lipid control. The findings indicate that diabetes education programs should including strategies enhancing patients' knowledge, motivation and behavioral skills to effect behavior change.

Crisis and emergency risk communication as an integrative model.

This article describes a model of communication known as crisis and emergency risk communication (CERC). The model is outlined as a merger of many traditional notions of health and risk communication with work in crisis and disaster communication. The specific kinds of communication activities that should be called for at various stages of disaster or crisis development are outlined. Although crises are by definition uncertain, equivocal, and often chaotic situations, the CERC model is presented as a tool health communicators can use to help manage these complex events.

Influence of atmospheric turbulence on the quantum polarization state

2018-03-01

In order to study the influence of atmospheric turbulence on the polarization state of the free space quantum communication, the relationship between the refractive index and altitude, the refractive index structure constant and the turbulence dimension is deduced based on two different atmospheric refractive index structural constants models. The turbulence intensity factor κ is introduced and the equation of the variation of the quantum polarization degree with turbulence intensity is established. Through the simulation of the turbulent refractive index and the performance of four different polarization states in the low altitude turbulence environment, the results show that the atmospheric turbulence in the near ground will affect the fluctuation of the degree of polarization, and the degree of polarization varies linearly with the change of turbulence intensity. In the case of polarization |H>, the range of polarization |H> varies from 0 to 0.14 with the change of turbulence intensity. The influence of atmospheric turbulence on four different polarization states is different, and the degree of |H> and |V> depolarization is greater in the daytime and back. The depolarization degree of |-> at night is greater. The relationship between the degree of polarization and the change of turbulence intensity is analyzed by mathematical modeling, which is helpful to select the reasonable experimental scheme and compensate the change of polarization state in the aviation quantum Secure communication channel.

A Teaching Framework for Cross-cultural Health Care—Application in Family Practice

Significant demographic changes in patient populations have contributed to an increasing awareness of the impact of cultural diversity on the provision of health care. For this reason methods are being developed to improve the cultural sensitivity of persons responsible for giving health care to patients whose health beliefs may be at variance with biomedical models. Building on methods of elicitation suggested in the literature, we have developed a set of guidelines within a framework called the LEARN model. Health care providers who have been exposed to this educational framework and have incorporated this model into the normal structure of the therapeutic encounter have been able to improve communication, heighten awareness of cultural issues in medical care and obtain better patient acceptance of treatment plans. The emphasis of this teaching model is not on the dissemination of particular cultural information, though this too is helpful. The primary focus is rather on a suggested process for improved communication, which we see as the fundamental need in cross-cultural patient-physician interactions. PMID:6666112

Packet Traffic Dynamics Near Onset of Congestion in Data Communication Network Model

2006-05-01

The dominant technology of data communication networks is the Packet Switching Network (PSN). It is a complex technology organized as various hierarchical layers according to the International Standard Organization (ISO) Open Systems Interconnect (OSI) Reference Model. The Network Layer of the ISO OSI Reference Model is responsible for delivering packets from their sources to their destinations and for dealing with congestion if it arises in a network. Thus, we focus on this layer and present an abstraction of the Network Layer of the ISO OSI Reference Model. Using this abstraction we investigate how onset of traffic congestion is affected for various routing algorithms by changes in network connection topology. We study how aggregate measures of network performance depend on network connection topology and routing. We explore packets traffic spatio-temporal dynamics near the phase transition point from free flow to congestion for various network connection topologies and routing algorithms. We consider static and adaptive routings. We present selected simulation results.

We are finally starting to see the early signs of transformation in scholarly publishing. The innovations we've been expecting for years are slowly being adopted, but we can also expect the pace of change to accelerate in the coming 3 to 5 years. At the same time, many of rituals and artifacts of the scholarly communication lifecycle are still rooted in a centuries-old model. What are the primary goals of scholarly communication, and what will be the future role of librarians in that cycle? What are the obstacles in information flow (many of our own design) that can be removed? Is the library profession moving fast enough to stay ahead of the curve... or are we ever going to be struggling to keep up? With the advent of the data deluge, all-XML workflows, the semantic Web, cloud services and increasingly intelligent mobile devices - what are the implications for libraries, archivists, publishers, scholarly societies as well as individual researchers and scholars? The opportunities are many - but capitalizing on this ever-evolving landscape will require significant changes to our field, changes that we are not currently well-positioned to enact. This talk will map the current scholarly communication landscape - highlighting recent exciting developments, and will focus on the repercussions and some specific recommendations for the broader field of information management.

Adapting and Bending the Portal to the Public: Evaluation of an NSF-Funded Science Communication Model for UNAVCO's Geoscience Summer Internships

UNAVCO is a National Science Foundation (NSF) facility specializing in geodesy. As part of its education and outreach work, it operates annual summer internships. In 2016, UNAVCO joined the Portal to the Public (PoP) network and the PoP model was adapted and bent to provide science communication professional development for summer interns. PoP is one way that UNAVCO invests in and trains future generations of geoscientists. The NSF-funded PoP initiative and its network, PoPNet, is a premier outreach framework connecting scientists and public audiences for over a decade. PoPNet is a network of sixty organizations committed to using the PoP method to engage the public in face-to-face interactions with practicing scientists. The PoP initiative provides professional development to scientists focused on best practices in science communication, helps them to develop an interactive exhibit consistent with their current research, and offers them a venue for interacting with the public. No other evaluation work to date has examined how summer internships can uptake the PoP model. This presentation focuses on evaluation findings from two cohorts of summer interns across two years. Three primary domains were assessed: how demographic composition across cohorts required changes to the original PoP framework, which of the PoP professional development trainings were valued (or not) by interns, and changes to intern knowledge, attitudes, and abilities to communicate science. Analyses via surveys and interviews revealed that level of intern geoscience knowledge was a major factor in deciding the focus of the work, specifically whether to create new hands-on exhibits or use existing ones. Regarding the use of PoP trainings, there was no obvious pattern in what interns preferred. Most growth and learning for interns occurred during and after the outreach activity. Results of this evaluation can be used to inform other applications of the PoP approach in summer internships.

Hysteresis in consumer markets with focus on the mobile communications market

NASA Astrophysics Data System (ADS)

Twomey, C.

2008-11-01

Our aim here is to try to identify hysteresis in the switching patterns of consumers in the Irish mobile phone industry. It was not until the introduction by the Communication Regulator of full-number portability that consumers began to take advantage of the savings that switching mobile phone operator could produce. As with most relatively new industries, the awareness of savings is clouded by a lack of understanding of whats on offer and an underlying fear of change from something they have only just started to comprehend. With people changing company loyalties more frequently than ever at the prospect of better, more cost-efficient services, it is now the million euro question for the phone companies on how close they should match each others' offers to maximize their profits, and what their best pricing strategy should be to obtain an even larger share of the market. Through the use of experimental economics and by modelling switching behaviour using the Preisach model, along with observed and market data, we hope to both pose this problem and start the journey to answering this question.

Movement: How the Brain Communicates with the World.

PubMed

Schwartz, Andrew B

2016-03-10

Voluntary movement is a result of signals transmitted through a communication channel that links the internal world in our minds to the physical world around us. Intention can be considered the desire to effect change on our environment, and this is contained in the signals from the brain, passed through the nervous system to converge on muscles that generate displacements and forces on our surroundings. The resulting changes in the world act to generate sensations that feed back to the nervous system, closing the control loop. This Perspective discusses the experimental and theoretical underpinnings of current models of movement generation and the way they are modulated by external information. Movement systems embody intentionality and prediction, two factors that are propelling a revolution in engineering. Development of movement models that include the complexities of the external world may allow a better understanding of the neuronal populations regulating these processes, as well as the development of solutions for autonomous vehicles and robots, and neural prostheses for those who are motor impaired.

Evaluating the effects of ideology on public understanding of climate change science: how to improve communication across ideological divides?

PubMed

Zia, Asim; Todd, Anne Marie

2010-11-01

While ideology can have a strong effect on citizen understanding of science, it is unclear how ideology interacts with other complicating factors, such as college education, which influence citizens' comprehension of information. We focus on public understanding of climate change science and test the hypotheses: [H1] as citizens' ideology shifts from liberal to conservative, concern for global warming decreases; [H2] citizens with college education and higher general science literacy tend to have higher concern for global warming; and [H3] college education does not increase global warming concern for conservative ideologues. We implemented a survey instrument in California's San Francisco Bay Area, and employed regression models to test the effects of ideology and other socio-demographic variables on citizen concern about global warming, terrorism, the economy, health care and poverty. We are able to confirm H1 and H3, but reject H2. Various strategies are discussed to improve the communication of climate change science across ideological divides.

This study aimed to evaluate the impact of a community-based health education and communication programme on reducing liver fluke infections caused by the consumption of uncooked fish among people in a high-risk area of Thailand. The study was quasi-experimental in nature, with three-stages. Stage 1 involved a situational and capacity analysis of designated communities in Khon Kaen province. This was followed by the development of a model for community-based health education and communication to prevent liver fluke infections among high-risk people, and, lastly, implementation and evaluation of the model were performed. Data were collected using both qualitative and quantitative methods. In total, 390 people were surveyed, and quasi-experimental and comparison groups, each with 90 people, were assessed between May 2011 and April 2012. Analysis was using statistical OR, 95 % CI, the Willcoxon matched pairs signed ranks test, the chi-square test, and the Mann-Whitney U test. The findings showed that most respondents had a high level of knowledge and understanding of liver fluke disease (89.5%, 95% CI:86.0-92.4), and positive attitudes toward the prevention of the disease (94.4%, 95% CI:91.6-96.4). However, with regard to changes in consumption of uncooked fish, most respondents were still in the pre-contemplation phase (55.1%, 95% CI:50.0-60.1), followed by the contemplation phase, 22.6%. Furthermore, four factors were found to be associated with the consumption of uncooked fish--the consumption of alcohol (OR 4.16, 95% CI:1.79-9.65), gender (OR 3.17 , 95% CI:1.53-6.54), smoking (OR 3.03, 95% CI:1.31-7.05), and age 40 years and above (OR 2.68, 95% CI:1.02-7.05). After nine months of the health education and communication programme using local media based on local wisdom, culture and persons, the results showed that, compared to the control group, members of the experimental group had a higher level of knowledge, a better attitude and lower levels of ill- advised consumption behaviour. Also, it was found that consumption of uncooked fish, by an assessment of the level of stage of change, was reduced. (p-value 0.002). The health education and communication programme developed as part of the study was effective in changing the consumption of uncooked fish. Therefore, this approach should be promoted in other high-risk areas in Thailand in the future.

On the use of Empirical Data to Downscale Non-scientific Scepticism About Results From Complex Physical Based Models

Germer, S.; Bens, O.; Hüttl, R. F.

2008-12-01

The scepticism of non-scientific local stakeholders about results from complex physical based models is a major problem concerning the development and implementation of local climate change adaptation measures. This scepticism originates from the high complexity of such models. Local stakeholders perceive complex models as black-box models, as it is impossible to gasp all underlying assumptions and mathematically formulated processes at a glance. The use of physical based models is, however, indispensible to study complex underlying processes and to predict future environmental changes. The increase of climate change adaptation efforts following the release of the latest IPCC report indicates that the communication of facts about what has already changed is an appropriate tool to trigger climate change adaptation. Therefore we suggest increasing the practice of empirical data analysis in addition to modelling efforts. The analysis of time series can generate results that are easier to comprehend for non-scientific stakeholders. Temporal trends and seasonal patterns of selected hydrological parameters (precipitation, evapotranspiration, groundwater levels and river discharge) can be identified and the dependence of trends and seasonal patters to land use, topography and soil type can be highlighted. A discussion about lag times between the hydrological parameters can increase the awareness of local stakeholders for delayed environment responses.

Science communication, typically defined as informing non-expert communities of societally relevant science, is persuaded by the magnitude and pace of scientific discoveries, as well as the urgency of societal issues wherein science may inform decisions. Perhaps nowhere is the connection between these facets stronger than in the marine and coastal Arctic where environmental change is driving advancements in our understanding of natural and socio-ecological systems while paving the way for a new assortment of arctic stakeholders, who generally lack adequate operational knowledge. As such, the Arctic provides opportunity to advance the role of science communication into a collaborative process of engagement and co-communication. To date, the communication of arctic change falls within four primary genres, each with particular audiences in mind. The New Arctic communicates an arctic of new stakeholders scampering to take advantage of unprecedented access. The Global Arctic conveys the Arctic's importance to the rest of the world, primarily as a regulator of lower-latitude climate and weather. The Intra-connected Arctic emphasizes the increasing awareness of the interplay between system components, such as between sea ice loss and marine food webs. The Transforming Arctic communicates the region's trajectory relative to the historical Arctic, acknowledging the impacts on indigenous peoples. The broad societal consensus on climate change in the Arctic as compared to other regions in the world underscores the opportunity for co-communication. Seizing this opportunity requires the science community's engagement with stakeholders and indigenous peoples to construct environmental change narratives that are meaningful to climate responses relative to non-ecological priorities (e.g., infrastructure, food availability, employment, or language). Co-communication fosters opportunities for new methods of and audiences for communication, the co-production of new interdisciplinary knowledge and cross-epistemological perspectives, and direct feedback to the science community regarding the societal implications of future research. Currently, the Study for Environmental Arctic Change (SEARCH) is developing this necessary cadre of co-communicators of marine and coastal arctic change.

Cancer experts engage in public communication whenever they promote their research or practice, respond to media inquiries, or use social media. In a changing communication landscape characterized by new technologies and heightened attention to cancer controversies, these activities may pose ethical challenges. This study was designed to evaluate existing resources to help clinicians navigate their public communication activities. We conducted a systematic, qualitative content analysis of codes of ethics, policy statements, and similar documents disseminated by professional medical and nursing societies for their members. We examined these documents for four types of content related to public communication: communication via traditional media; communication via social media; other communication to the public, policy, and legal spheres; and nonspecific language regarding public communication. We identified 46 documents from 23 professional societies for analysis. Five societies had language about traditional news media communication, five had guidance about social media, 11 had guidance about other communication domains, and 15 societies offered general language about public communication. The limited existing guidance focused on ethical issues related to patients (such as privacy violations) or clinicians (such as accuracy and professional boundaries), with less attention to population or policy impact of communication. Cancer-related professional societies might consider establishing more specific guidance for clinicians concerning their communication activities in light of changes to the communication landscape. Additional research is warranted to understand the extent to which clinicians face ethical challenges in public communication.

Brief communication: The global signature of post-1900 land ice wastage on vertical land motion

Melting glaciers, ice caps and ice sheets have made an important contribution to sea-level rise through the last century. Self-attraction and loading effects driven by shrinking ice masses cause a spatially varying redistribution of ocean waters that affects reconstructions of past sea level from sparse observations. We model the solid-earth response to ice mass changes and find significant vertical deformation signals over large continental areas. We show how deformation rates have been strongly varying through the last century, which implies that they should be properly modelled before interpreting and extrapolating recent observations of vertical land motion and sea-level change.

This paper provides highlights of a utilization-focused evaluation of a collaborative Pan-Arctic Inuit Wellness TV Series that was broadcast live in Alaska and Canada in May 2009. This International Polar Year (IPY) communication and outreach project intended to (1) share information on International Polar Year research progress, disseminate findings and explore questions with Inuit in Alaska, Canada and Greenland; (2) provide a forum for Inuit in Alaska, Canada and Greenland to showcase innovative health and wellness projects; (3) ensure Inuit youth and adult engagement throughout; and (4) document and reflect on the overall experience for the purposes of developing and "testing" a participatory communication model. Utilization-focused formative evaluation of the project, with a focus on overall objectives, key messages and lessons learned to facilitate program improvement. Participant observation, surveys, key informant interviews, document review and website tracking. Promising community programs related to 3 themes - men's wellness, maternity care and youth resilience - in diverse circumpolar regions were highlighted, as were current and stillevolving findings from ongoing Arctic research. Multiple media methods were used to effectively deliver and receive key messages determined by both community and academic experts. Local capacity and new regional networks were strengthened. Evidence-based resources for health education and community action were archived in digital formats (websites and DVDs), increasing accessibility to otherwise isolated individuals and remote communities. The Pan-Arctic Inuit Wellness TV Series was an innovative, multi-dimensional communication project that raised both interest and awareness about complex health conditions in the North and stimulated community dialogue and potential for increased collaborative action. Consistent with a communication for social change approach, the project created new networks, increased motivation to act and provided new tools to do so, and increased local community involvement and "voice" in the discussion and dissemination of successful strategies to promote Inuit wellness.

Understanding Global Change: Frameworks and Models for Teaching Systems Thinking

The scientific and education communities must impart to teachers, students, and the public an understanding of how the various factors that drive climate and global change operate, and why the rates and magnitudes of these changes related to human perturbation of Earth system processes today are cause for deep concern. Even though effective educational modules explaining components of the Earth and climate system exist, interdisciplinary learning tools are necessary to conceptually link the causes and consequences of global changes. To address this issue, the Understanding Global Change Project at the University of California Museum of Paleontology (UCMP) at UC Berkeley developed an interdisciplinary framework that organizes global change topics into three categories: (1) causes of climate change, both human and non-human (e.g., burning of fossil fuels, deforestation, Earth's tilt and orbit), (2) Earth system processes that shape the way the Earth works (e.g., Earth's energy budget, water cycle), and (3) the measurable changes in the Earth system (e.g., temperature, precipitation, ocean acidification). To facilitate student learning about the Earth as a dynamic, interacting system, a website will provide visualizations of Earth system models and written descriptions of how each framework topic is conceptually linked to other components of the framework. These visualizations and textual summarizations of relationships and feedbacks in the Earth system are a unique and crucial contribution to science communication and education, informed by a team of interdisciplinary scientists and educators. The system models are also mechanisms by which scientists can communicate how their own work informs our understanding of the Earth system. Educators can provide context and relevancy for authentic datasets and concurrently can assess student understanding of the interconnectedness of global change phenomena. The UGC resources will be available through a web-based platform and scalable professional development programming to facilitate systemic changes in the teaching and learning about climate and global change. We are establishing a diverse community of scientists and educators across the country that are using these tools, and plan to create local networks supported by UGC staff and partners.

Testing a pharmacist-patient relationship quality model among older persons with diabetes.

Worley, Marcia M

2006-03-01

Considering recent changes to the Medicare program, pharmacists will have unique opportunities to be reimbursed for providing Medication Therapy Management Services to older persons with diabetes. A high-quality pharmacist-patient relationship can lay the foundation for effective provision of Medication Therapy Management Services and improved care in this cohort. To test a pharmacist-patient relationship quality model in a group of older persons with diabetes from the patient's perspective. Antecedents to relationship quality were pharmacist participative behavior/patient-centeredness of relationship, patient participative behavior, and pharmacist-patient interpersonal communication. Pharmacist-patient relationship commitment was the outcome of relationship quality studied. Data were collected via mailed questionnaire from a random sample of 600 community-dwelling adults in the United States who (1) were 65 years of age and older, (2) had type 1 or type 2 diabetes, (3) used at least one prescription medication to treat their diabetes, and (4) used some type of nonmail order pharmacy as their primary source of obtaining prescription medications. Model relationships were tested using path analysis. The adjusted response rate was 41.6% (221/531). The models explained 47% and 49% of the variance in relationship quality and relationship commitment, respectively. In the relationship quality model, pharmacist participative behavior/patient-centeredness of relationship (beta=.51, P<.001) and pharmacist-patient interpersonal communication (beta=.17, P=.008) had direct effects on relationship quality. In the relationship commitment model, relationship quality had a direct effect on relationship commitment (beta=.60, P<.001). Pharmacist participative behavior/patient-centeredness and pharmacist-patient interpersonal communication had indirect effects on relationship commitment through their effects on relationship quality, which is a mediator in the model. Results affirm findings from previous research showing that patients' perceptions of pharmacist participative behavior/patient-centeredness of relationship and pharmacist-patient interpersonal communication are positively related to perceptions of relationship quality. Also, relationship quality is a strong mediator between pharmacist participative behavior/patient-centeredness of relationship and relationship commitment, as well as between pharmacist-patient interpersonal communication and relationship commitment.

Model-Based Analysis of Cell Cycle Responses to Dynamically Changing Environments

PubMed Central

Seaton, Daniel D; Krishnan, J

2016-01-01

Cell cycle progression is carefully coordinated with a cell’s intra- and extracellular environment. While some pathways have been identified that communicate information from the environment to the cell cycle, a systematic understanding of how this information is dynamically processed is lacking. We address this by performing dynamic sensitivity analysis of three mathematical models of the cell cycle in Saccharomyces cerevisiae. We demonstrate that these models make broadly consistent qualitative predictions about cell cycle progression under dynamically changing conditions. For example, it is shown that the models predict anticorrelated changes in cell size and cell cycle duration under different environments independently of the growth rate. This prediction is validated by comparison to available literature data. Other consistent patterns emerge, such as widespread nonmonotonic changes in cell size down generations in response to parameter changes. We extend our analysis by investigating glucose signalling to the cell cycle, showing that known regulation of Cln3 translation and Cln1,2 transcription by glucose is sufficient to explain the experimentally observed changes in cell cycle dynamics at different glucose concentrations. Together, these results provide a framework for understanding the complex responses the cell cycle is capable of producing in response to dynamic environments. PMID:26741131

Assured communications and combat resiliency: the relationship between effective national communications and combat efficiency

2009-05-01

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

Tropical Hydroclimate Change during Heinrich Stadial 1: An Integrative Proxy-Model Synthesis

We explore the response of tropical climate to abrupt cooling of the North Atlantic (NA) during Heinrich Stadial 1 (HS1) combining paleoclimate proxies with model simulations. A total of 146 published paleoclimate records from tropical locations are used to categorize whether HS1 was wetter, drier, or unchanged relative to a deglacial baseline state. Only records with sufficient resolution to resolve HS1 and sufficient length to characterize the deglacial trend are considered. This synthesis reveals large-scale patterns of hydroclimate change relative to glacial conditions, confirming previously reported weaker Indian summer monsoon, a wetter southern Africa, and drying over the Caribbean. Our synthesis also reveals large-scale drying over the Maritime continent as well as wetter conditions in northern Australia and southern tropical South America. Our reinterpretation of the available proxy data reveals far more complexity and uncertainties for equatorial East Africa, a region that appears to straddle a pattern of dryer conditions to the north and wetter conditions to the south. Overall, these patterns of hydroclimate change depart from a southward shift of the Inter Tropical Convergence Zone (ITCZ), particularly outside the tropical Atlantic. We explore mechanisms driving these changes using a multi-model ensemble of "hosing" simulations performed relative to glacial conditions. The models show robust weakening of the Afro-Asian Monsoon, which we attribute to ventilation of colder mid-latitude air. Not all models simulate the remaining patterns inferred from the proxy data. The best-agreeing models indicate that cooling over the tropical NA and the Caribbean may be essential to communicate the response to the global tropics. This response can induce warming over the tropical South Atlantic via the wind-evaporation-SST feedback, driving wetter conditions in South Africa and tropical South America. Cooling over the Caribbean is communicated to the Pacific over the Central American isthmus resulting in an El Niño-like pattern accompanied by drying over the Maritime Continent - as seen in the proxy data. Together these results show a dominant role for altered tropical SST gradients driving changes in tropical rainfall, and a lesser role for inter-hemispheric shifts in the ITCZ.

2014-09-01

In this study, we explored the relationship between changes in resident health outcomes, practitioner communication patterns, and practitioner perceptions of group effectiveness within a quality-improvement collaborative of nursing home clinicians. Survey and interview data were collected from nursing home clinicians participating in a quality-improvement collaborative. Quality-improvement outcomes were evaluated using US Federal and State minimum dataset measures. Models were specified evaluating the relationships between resident outcomes, staff perceptions of communication patterns, and staff perceptions of collaborative effectiveness. Interview data provided deeper understanding of the quantitative findings. Reductions in fall rates were highest in facilities where respondents experienced the highest levels of communication with collaborative members outside of scheduled meetings, and where respondents perceived that the collaborative kept them informed and provided new ideas. Clinicians observed that participation in a quality-improvement collaborative positively influenced the ability to share innovative ideas and expand the quality-improvement program within their nursing home. For practitioners, a high level of communication, both inside and outside of meetings, was key to making measurable gains in resident health outcomes. © 2013 Wiley Publishing Asia Pty Ltd.

Effective communication of information about chemical hazards.

PubMed

Lee, T R

1986-05-01

Given that the best available means have been used to assess the risks arising from a chemical process or product, it is a crucial aspect of management to inform the employees and the public. This task of communicating may fall to industry, government, regulating authority, professional association or an environmental protection group. It requires some understanding of the public's perceptions of the risks involved and an ethical duty to try to modify attitudes judged to be either over-anxious or complacent. There is as yet no structured knowledge on communication about chemical hazards as such. Also, circumstances vary enormously. Hence, this paper deploys the general analytic framework constructed within social psychology and reviews the extensive experimental research (and some field studies) with the aim of providing understanding and some guidance. It considers the basic modelling of attitude change as induced by printed or verbal communications. The variables influencing the effectiveness of communications are divided into: the source (e.g. his/her credibility, power or attractiveness); the message (e.g. emotional versus logical; one-sided versus both-sided arguments); and modality or media effects (e.g. spoken versus written; the mass media; campaigns).

The evolution and impact of PCS technology

NASA Astrophysics Data System (ADS)

Lawson, John R.

1994-09-01

In today's mobile society, communications services that focus on location (wired) are increasingly inadequate. But services that center around the individual (wireless) are being developed to serve society in a way that only recently could consumers have imagined. People-oriented communications tools will make life simpler and more productive. The essence of this concept is captured in a family of wireless services and devices that allow the user to communicate independent of location--Personal Communications Services, known as PCS. First generation PCS devices such a pagers and cellular phones were the instruments of the first wireless revolution, but they will soon be forced to relinquish the spotlight to the new generation of PCS and what should be a dazzling variety of individualized advanced telecommunications services and devices. Within the next two years, these new PCS models, recently described as 'the most exciting development in telecommunications since the breakup of AT&T,' should hit the marketplace, changing the way we communicate and, in turn, the way we live. This paper explores the status and likely development of PCS generally, including 'new PCS.'

Prior Family Communication and Consent to Organ Donation: Using Intensive Care Physicians’ Perception to Model Decision Processes

PubMed Central

Schulz, Peter J.; van Ackere, Ann; Hartung, Uwe; Dunkel, Anke

2012-01-01

Generally, the Swiss hold favourable attitudes to organ donation, but only few carry a donor card. If no card is found on a potential donor, families have to be approached about donation. The aim of this paper is to model the role that some family communication factors play in the family decision to consent or not to organ donation by a brain dead relative. Information was gathered in face-to-face interviews, using a questionnaire and recording open answers and comments. Eight heads of intensive care units (ICU) of Swiss hospitals and one representative from Swisstransplant were interviewed. Questions asked respondents to estimate the prevalence and effect of communication factors in families facing a decision to consent to donation. Answers were averaged for modelling purposes. Modelling also relies on a previous representative population survey for cross-validation. The family of the deceased person is almost always approached about donation. Physicians perceive that prior thinking and favourable predisposition to donation are correlated and that the relatives’ predisposition is the most important factor for the consent to donation, up to the point that a negative predisposition may override an acknowledged wish of the deceased to donate. Donor cards may trigger family communication and ease the physicians’ approach to family about donation. Campaigns should encourage donate-willing people to talk to their families about it, make people think about organ donation and try to change unfavourable predispositions. Acknowledgement the authors wish to thank the interviewees whose collaboration has provided them an overview of today’s situation in Switzerland. PMID:25170455

Persuasive communication: A theoretical model for changing the attitude of preservice elementary teachers toward metric conversion

NASA Astrophysics Data System (ADS)

Shrigley, Robert L.

This study was based on Hovland's four-part statement, Who says what to whom with what effect, the rationale for persuasive communication, a theoretical model for modifying attitudes. Part I was a survey of 139 perservice elementary teachers from which were generated the more credible characteristics of metric instructors, a central element in the who component of Hovland's model. They were: (1) background in mathematics and science, (2) fluency in metrics, (3) capability of thinking metrically, (4) a record of excellent teaching, (5) previous teaching of metric measurement to children, (6) responsibility for teaching metric content in methods courses and (7) an open enthusiasm for metric conversion. Part II was a survey of 45 mathematics educators where belief statements were synthesized for the what component of Hovland's model. It found that math educators support metric measurement because: (1) it is consistent with our monetary system; (2) the conversion of units is easier into metric than English; (3) it is easier to teach and easier to learn than English measurement; there is less need for common fractions; (4) most nations use metric measurement; scientists have used it for decades; (5) American industry has begun to use it; (6) metric measurement will facilitate world trade and communication; and (7) American children will need it as adults; educational agencies are mandating it. With the who and what of Hovland's four-part statement defined, educational researchers now have baseline data to use in testing experimentally the effect of persuasive communication on the attitude of preservice teachers toward metrication.

Time lag and communication in changing unpopular norms.

PubMed

Gërxhani, Klarita; Bruggeman, Jeroen

2015-01-01

Humans often coordinate their social lives through norms. When a large majority of people are dissatisfied with an existing norm, it seems obvious that they will change it. Often, however, this does not occur. We investigate how a time lag between individual support of a norm change and the change itself hinders such change, related to the critical mass of supporters needed to effectuate the change, and the (im)possibility of communicating about it. To isolate these factors, we utilize a laboratory experiment. As predicted, we find unambiguous effects of time lag on precluding norm change; a higher threshold for a critical mass does so as well. Communication facilitates choosing superior norms but it does not necessarily lead to norm change when the uncertainty on whether there will be a norm change in the future is high. Communication seems to help coordination on actions at the present but not the future. Hence, the uncertainty driven by time lag makes individuals choose the status quo, here the unpopular norm.

The purpose of this study is to analyze the impacts of final demand changes on total output of Japanese Information and Communication Technologies (ICT) sectors in future time. This study employs one of analysis tool in Input-Output (IO) analysis, demand-pull IO quantity model, in achieving the purpose. There are three final demand changes used in this study, namely (1) export, (2) import, and (3) outside households consumption changes. This study focuses on "pure change" condition, the condition that final demand changes only appear in analyzed sectors. The results show that export and outside households consumption modifications give positive impact while opposite impact could be seen in import change.

A conceptual model of the role of communication in surrogate decision making for hospitalized adults.

2012-04-01

To build a conceptual model of the role of communication in decision making, based on literature from medicine, communication studies and medical ethics. We proposed a model and described each construct in detail. We review what is known about interpersonal and patient-physician communication, described literature about surrogate-clinician communication, and discussed implications for our developing model. The communication literature proposes two major elements of interpersonal communication: information processing and relationship building. These elements are composed of constructs such as information disclosure and emotional support that are likely to be relevant to decision making. We propose these elements of communication impact decision making, which in turn affects outcomes for both patients and surrogates. Decision making quality may also mediate the relationship between communication and outcomes. Although many elements of the model have been studied in relation to patient-clinician communication, there is limited data about surrogate decision making. There is evidence of high surrogate distress associated with decision making that may be alleviated by communication-focused interventions. More research is needed to test the relationships proposed in the model. Good communication with surrogates may improve both the quality of medical decisions and outcomes for the patient and surrogate. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

The RN-BSN student: developing a model of empowerment.

1996-03-01

Nursing practice is being redefined. Today's graduating nurse is practicing in a tomorrow full of unknowns. The relevancy of traditional nursing education is being questioned in today's health care climate of crisis. In an attempt to prepare the graduating RN-BSN student to cope with these changes, nurse educators developed a process of empowerment. The framework for this effort was derived from the curriculum revolution, adult learning theory and empowerment research. The faculty defined empowerment as both an interpersonal process and an outcome. A graphic model has been created consisting of the four elements of empowerment: collegiality, communication, autonomy and accountability. Learning experiences are selected based upon these four elements. Teaching strategies are identified. Positive changes in student behavior have been reported anecdotally. The faculty are beginning the next phase: designing a research project to investigate behavior changes related to this empowerment model.

How NASA is building and sustaining a community of scientist-communicators through virtual technology, graphic facilitation and other community-building tools

In 2013 NASA launched its first agency-wide effort to cultivate and support scientist-communicators. The multiple motivations behind this effort are complex and overlapping, and include a desire to connect the agency's workforce to its mission and to each other in the post-Space Shuttle era; a shift in how the agency and the world communicates about science; the current public perception of science and of NASA, and a desire to share the stories of the real people behind the agency's technical work. Leaders in the NASA science, communications and public outreach communities partnered with the agency's training and leadership development organization to: identify and fully characterize the need for training and development in science communication, experiment with various learning models, and invite early-adopter scientists to evaluate these models for future agency investment. Using virtual collaboration technology, graphic facilitation, and leadership development methods, we set out to create an environment where scientist-communicators can emerge and excel. First, we asked scientists from across the agency to identify their motivations, opportunities, barriers and areas of interest in science communication. Scientists identified a need to go beyond traditional media training, a need for continuous practice and peer feedback, and a need for agency incentives and sustained support for this kind of work. This community-driven approach also uncovered a serious need for communication support in the wake of diminishing resources for travel and conference attendance. As a first step, we offered a series of virtual learning events - highly collaborative working sessions for scientists to practice their communication technique, develop and apply new skills to real-world situations, and gain valuable feedback from external subject matter experts and fellow scientists from across the agency in a supportive environment. Scientists from ten NASA centers and a broad range of research disciplines - from astrophysics to climate change to aeronautics - took part in these virtual events. This newly connected community provided continuous feedback and recommendations for how they and the agency can continue to cultivate and support scientist-communicators over the long-term. By inviting scientists to communicate in new ways using new tools, we are modeling the type of innovative communication we hope to see, and are gradually elevating scientists' exposure to and comfort level with new communication technologies. Our next challenge is to provide a deeper learning experience and strengthen connections within this community through a series of face-to-face workshops at NASA centers. We are also investigating ways to broaden and sustain the supportive environment - both virtual and institutional - needed for this new distributed network of scientist-communicators to thrive.

Development of a behaviour change intervention: a case study on the practical application of theory

PubMed Central

2014-01-01

Background Use of theory in implementation of complex interventions is widely recommended. A complex trial intervention, to enhance self-management support for people with osteoarthritis (OA) in primary care, needed to be implemented in the Managing Osteoarthritis in Consultations (MOSAICS) trial. One component of the trial intervention was delivery by general practitioners (GPs) of an enhanced consultation for patients with OA. The aim of our case study is to describe the systematic selection and use of theory to develop a behaviour change intervention to implement GP delivery of the enhanced consultation. Methods The development of the behaviour change intervention was guided by four theoretical models/frameworks: i) an implementation of change model to guide overall approach, ii) the Theoretical Domains Framework (TDF) to identify relevant determinants of change, iii) a model for the selection of behaviour change techniques to address identified determinants of behaviour change, and iv) the principles of adult learning. Methods and measures to evaluate impact of the behaviour change intervention were identified. Results The behaviour change intervention presented the GPs with a well-defined proposal for change; addressed seven of the TDF domains (e.g., knowledge, skills, motivation and goals); incorporated ten behaviour change techniques (e.g., information provision, skills rehearsal, persuasive communication); and was delivered in workshops that valued the expertise and professional values of GPs. The workshops used a mixture of interactive and didactic sessions, were facilitated by opinion leaders, and utilised ‘context-bound communication skills training.’ Methods and measures selected to evaluate the behaviour change intervention included: appraisal of satisfaction with workshops, GP report of intention to practise and an assessment of video-recorded consultations of GPs with patients with OA. Conclusions A stepped approach to the development of a behaviour change intervention, with the utilisation of theoretical frameworks to identify determinants of change matched with behaviour change techniques, has enabled a systematic and theory-driven development of an intervention designed to enhance consultations by GPs for patients with OA. The success of the behaviour change intervention in practice will be evaluated in the context of the MOSAICS trial as a whole, and will inform understanding of practice level and patient outcomes in the trial.

Davidson, M. A.

2016-12-01

It is increasingly clear that our scientific capabilities are under appreciated and underutilized, especially with regard to highly contentious issues such as planning, disaster policy, climate change and its attendant effects. Part of this is due to cultural differences in perception and communication. Another component is our ability to bring forth positive solutions has lagged behind our modeling capabilities. And, finally, there is just real world politics. Addressing these shortcomings may help advance our efforts to adapt to an increasingly changing environment.

A marketing model: applications for dietetic professionals.

PubMed

Parks, S C; Moody, D L

1986-01-01

Traditionally, dietitians have communicated the availability of their services to the "public at large." The expectation was that the public would respond favorably to nutrition programs simply because there was a consumer need for them. Recently, however, both societal and consumer needs have changed dramatically, making old communication strategies ineffective and obsolete. The marketing discipline has provided a new model and new decision-making tools for many health professionals to use to more effectively make their services known to multiple consumer groups. This article provides one such model as applied to the dietetic profession. The model explores a definition of the business of dietetics, how to conduct an analysis of the environment, and, finally, the use of both in the choice of new target markets. Further, the model discusses the major components of developing a marketing strategy that will help the practitioner to be competitive in the marketplace. Presented are strategies for defining and re-evaluating the mission of the profession, for using future trends to identify new markets and roles for the profession, and for developing services that make the profession more competitive by better meeting the needs of the consumer.

The Health Belief Model as an Explanatory Framework in Communication Research: Exploring Parallel, Serial, and Moderated Mediation

Jones, Christina L.; Jensen, Jakob D.; Scherr, Courtney L.; Brown, Natasha R.; Christy, Katheryn; Weaver, Jeremy

2015-01-01

The Health Belief Model (HBM) posits that messages will achieve optimal behavior change if they successfully target perceived barriers, benefits, self-efficacy, and threat. While the model seems to be an ideal explanatory framework for communication research, theoretical limitations have limited its use in the field. Notably, variable ordering is currently undefined in the HBM. Thus, it is unclear whether constructs mediate relationships comparably (parallel mediation), in sequence (serial mediation), or in tandem with a moderator (moderated mediation). To investigate variable ordering, adults (N = 1,377) completed a survey in the aftermath of an 8-month flu vaccine campaign grounded in the HBM. Exposure to the campaign was positively related to vaccination behavior. Statistical evaluation supported a model where the indirect effect of exposure on behavior through perceived barriers and threat was moderated by self-efficacy (moderated mediation). Perceived barriers and benefits also formed a serial mediation chain. The results indicate that variable ordering in the Health Belief Model may be complex, may help to explain conflicting results of the past, and may be a good focus for future research. PMID:25010519

Communication among Oral Bacteria

Human oral bacteria interact with their environment by attaching to surfaces and establishing mixed-species communities. As each bacterial cell attaches, it forms a new surface to which other cells can adhere. Adherence and community development are spatiotemporal; such order requires communication. The discovery of soluble signals, such as autoinducer-2, that may be exchanged within multispecies communities to convey information between organisms has emerged as a new research direction. Direct-contact signals, such as adhesins and receptors, that elicit changes in gene expression after cell-cell contact and biofilm growth are also an active research area. Considering that the majority of oral bacteria are organized in dense three-dimensional biofilms on teeth, confocal microscopy and fluorescently labeled probes provide valuable approaches for investigating the architecture of these organized communities in situ. Oral biofilms are readily accessible to microbiologists and are excellent model systems for studies of microbial communication. One attractive model system is a saliva-coated flowcell with oral bacterial biofilms growing on saliva as the sole nutrient source; an intergeneric mutualism is discussed. Several oral bacterial species are amenable to genetic manipulation for molecular characterization of communication both among bacteria and between bacteria and the host. A successful search for genes critical for mixed-species community organization will be accomplished only when it is conducted with mixed-species communities. PMID:12209001

Dynamic Task Performance, Cohesion, and Communications in Human Groups.

PubMed

Giraldo, Luis Felipe; Passino, Kevin M

2016-10-01

In the study of the behavior of human groups, it has been observed that there is a strong interaction between the cohesiveness of the group, its performance when the group has to solve a task, and the patterns of communication between the members of the group. Developing mathematical and computational tools for the analysis and design of task-solving groups that are not only cohesive but also perform well is of importance in social sciences, organizational management, and engineering. In this paper, we model a human group as a dynamical system whose behavior is driven by a task optimization process and the interaction between subsystems that represent the members of the group interconnected according to a given communication network. These interactions are described as attractions and repulsions among members. We show that the dynamics characterized by the proposed mathematical model are qualitatively consistent with those observed in real-human groups, where the key aspect is that the attraction patterns in the group and the commitment to solve the task are not static but change over time. Through a theoretical analysis of the system we provide conditions on the parameters that allow the group to have cohesive behaviors, and Monte Carlo simulations are used to study group dynamics for different sets of parameters, communication topologies, and tasks to solve.

Developing and Optimising the Use of Logic Models in Systematic Reviews: Exploring Practice and Good Practice in the Use of Programme Theory in Reviews

PubMed Central

Kneale, Dylan; Thomas, James; Harris, Katherine

2015-01-01

Background Logic models are becoming an increasingly common feature of systematic reviews, as is the use of programme theory more generally in systematic reviewing. Logic models offer a framework to help reviewers to ‘think’ conceptually at various points during the review, and can be a useful tool in defining study inclusion and exclusion criteria, guiding the search strategy, identifying relevant outcomes, identifying mediating and moderating factors, and communicating review findings. Methods and Findings In this paper we critique the use of logic models in systematic reviews and protocols drawn from two databases representing reviews of health interventions and international development interventions. Programme theory featured only in a minority of the reviews and protocols included. Despite drawing from different disciplinary traditions, reviews and protocols from both sources shared several limitations in their use of logic models and theories of change, and these were used almost unanimously to solely depict pictorially the way in which the intervention worked. Logic models and theories of change were consequently rarely used to communicate the findings of the review. Conclusions Logic models have the potential to be an aid integral throughout the systematic reviewing process. The absence of good practice around their use and development may be one reason for the apparent limited utility of logic models in many existing systematic reviews. These concerns are addressed in the second half of this paper, where we offer a set of principles in the use of logic models and an example of how we constructed a logic model for a review of school-based asthma interventions.

NASA Technical Reports Server (NTRS)

1998-01-01

Coupled atmospheric and hydrodynamic forecast models were executed on the supercomputing resources of the National Center for Atmospheric Research (NCAR) in Boulder, Colorado and the Ohio Supercomputing Center (OSC)in Columbus, Ohio. respectively. The interoperation of the forecast models on these geographically diverse, high performance Cray platforms required the transfer of large three dimensional data sets at very high information rates. High capacity, terrestrial fiber optic transmission system technologies were integrated with those of an experimental high speed communications satellite in Geosynchronous Earth Orbit (GEO) to test the integration of the two systems. Operation over a spacecraft in GEO orbit required modification of the standard configuration of legacy data communications protocols to facilitate their ability to perform efficiently in the changing environment characteristic of a hybrid network. The success of this performance tuning enabled the use of such an architecture to facilitate high data rate, fiber optic quality data communications between high performance systems not accessible to standard terrestrial fiber transmission systems. Thus obviating the performance degradation often found in contemporary earth/satellite hybrids.

Non-Verbal Communicative Signals Modulate Attention to Object Properties

PubMed Central

Marno, Hanna; Davelaar, Eddy J.; Csibra, Gergely

2015-01-01

We investigated whether the social context in which an object is experienced influences the encoding of its various properties. We hypothesized that when an object is observed in a communicative context, its intrinsic features (such as its shape) would be preferentially encoded at the expense of its extrinsic properties (such as its location). In the three experiments, participants were presented with brief movies, in which an actor either performed a non-communicative action towards one of five different meaningless objects, or communicatively pointed at one of them. A subsequent static image, in which either the location or the identity of an object changed, tested participants’ attention to these two kinds of information. Throughout the three experiments we found that communicative cues tended to facilitate identity change detection and to impede location change detection, while in the non-communicative contexts we did not find such a bidirectional effect of cueing. The results also revealed that the effect of the communicative context was due to the presence of ostensive-communicative signals before the object-directed action, and not to the pointing gesture per se. We propose that such an attentional bias forms an inherent part of human communication, and function to facilitate social learning by communication. PMID:24294871

Marketing communications in nonbusiness situations or why it's so hard to sell brotherhood like soap.

PubMed

Rothschild, M L

1979-01-01

Marketing tools, techniques, and theories developed in the private sector can be applied in the public and nonprofit sectors; however, their limitations must be recognized. Nonbusiness communications campaigns should consider the involvedness (high or low) of the situation and the relevant segments, available positive and negative reinforcers, nonmonetary costs, the level of latent demand, and the wide range of communications alternatives. 5 hypotheses can be proposed regarding communications effectiveness outside of the private sector: 1) the lower the perceived personal value to the individual, relative to the cost, the more difficult the behavior change task and the lower the likelihood of success of marketing communications; 2) the lower the latent or pre-existing demand for the object, the more difficult the behavior change task and the lower the likelihood of marketing communications success; 3) the greater the involvement level of the object, situation, or issue, the more difficult the behavior change task and the lower the likelihood of marketing success; 4) the greater the past involvement level of the individual, the more difficult the behavior change task and the lower the likelihood of success; and 5) the greater the level of participation needed within the society, the more difficult the behavior change and the lower the likelihood of sucess of marketing communications. Many nonbusiness issues exist in either very high or very low involvement environments, calling for an enlarged set of communications strategies. More attention should be given to communications alternatives such as movies, television programs, and in-home and in-school educational communications, especially since it appears that public service spots are not very effective. Finally, more research is needed to generate and test the effectiveness of various marketing strategies aimed at overcoming inherent characteristics that suggest a low likelihood of success.

2017-07-01

To examine how communication between nurses and doctors occurred for managing medications in inpatient paediatric settings. Communication between health professionals influences medication incidents' occurrence and safe care. An ethnographic study was undertaken. Semi-structured interviews, observations and focus groups were conducted in three clinical areas of an Australian tertiary paediatric hospital. Data were transcribed verbatim and thematically analysed using the Medication Communication Model. The actual communication act revealed health professionals' commitment to effective medication management and the influence of professional identities on medication communication. Nurses and doctors were dedicated to providing safe, effective medication therapy for children, within their scope of practice and perceived role responsibilities. Most nurses and junior doctors used tentative language in their communication while senior doctors tended to use direct language. Irrespective of language style, nurses actively engaged with doctors to promote patients' needs. Yet, the medical hierarchical structure, staffing and attendant expectations influenced communication for medication management, causing frustration among nurses and doctors. Doctors' lack of verbal communication of documented changes to medication orders particularly troubled nurses. Nurses persisted in their efforts to acquire appropriate orders for safe medication administration to paediatric patients. Collaborative practice between nurses and doctors involved complex, symbiotic relationships. Their dedication to providing safe medication therapy to paediatric patients facilitated effective medication management. At times, shortcomings in interdisciplinary communication impacted on potential and actual medication incidents. Understanding of the complexities affecting medication communication between nurses and doctors helps to ensure interprofessional respect for each other's roles and inherent demands. Interdisciplinary education delivered in healthcare organisations would facilitate greater clarity in communication related to medications. Encouraging the use of concise, clear words in communication would help to promote improved understanding between parties, and accuracy and efficacy of medication management. © 2016 John Wiley & Sons Ltd.

Exploring Communication, Trust in Government, and Vaccination Intention Later in the 2009 H1N1 Pandemic: Results of a National Survey

PubMed Central

Parmer, John; Freimuth, Vicki S.; Hilyard, Karen M.; Musa, Donald; Kim, Kevin H.

2013-01-01

With the growing recognition of the critical role that risk communication plays in a public health emergency, a number of articles have provided prescriptive best practices to enhance such communication. However, little empirical research has examined perceptions of the quality of communication, the impact of uncertainty on changing communication, use of information sources, and trust in specific government spokespersons. Similarly, although there is significant conceptual focus on trust and communication as important in vaccination intent and acceptance, little research has explored these relationships empirically. We conducted an online survey in late January 2010 with a nationally representative sample (N=2,079) that included Hispanic and African American oversamples. The completion rate was 56%. We found that public health officials were the most trusted spokespersons, with President Obama being the most highly trusted elected official. Demographic variables, including race, accounted for 21% of the variance in trust of the president. Perceptions of the quality of communication were high, including significant understanding of uncertainty and appreciation for officials' openness about evolving information. Other factors that contributed to vaccination acceptance were quality of communication, closely following the news, and confidence in the vaccine because of a role model effect of the Obama daughters' immunizations; these factors significantly increased trust in government actions. Because the challenges of communication often vary over the course of a pandemic, there is a consistent need to pay close attention to both communication content and delivery and prepare public health officials at all levels to be effective communicators.

Decision Making and Communications Process Assessment of NASA Using Three Change Requests from the Space Launch System Program

NASA Technical Reports Server (NTRS)

Hicks, Karen Campbell

2015-01-01

This thesis investigated the communication and decision making process as part of the Systems Engineering practices at the NASA/Marshall Center to determine its level of effectiveness. Data was collected across three change requests to assess how decisions were made, how the decisions were communicated, and whether a process mattered in the formulation and dissemination of those decisions. Data results revealed the comprehensive decision making process for the technical change requests to be effective. Evidence revealed that the process was sufficiently tailored to accommodate the need of each individual technical change which promoted effective communication amongst the stakeholders in the formulation of the strategic decision recommendations elevated to upper management. However, data results also revealed the dissemination of the final decision and approval of the change requests from the higher organizational level down to all stakeholders was less effective. An establishment of a culmination meeting at the end of the change request decision process in which to close the communication loop with all entities would be beneficial.

Parents of children with eating disorders: developing theory-based health communication messages to promote caregiver well-being.

2014-01-01

Parents of children with eating disorders experience extreme emotional burden because of the intensity and duration of the recovery process. While parental involvement in a child's eating disorder treatment improves outcomes, parents often neglect their own well-being, which can impede their child's recovery. This study extends the research on caregivers and on health theory in practice by conducting formative research to develop a theory-based communication intervention encouraging parents to engage in adaptive coping and self-care behaviors. The Transactional Model of Stress and Coping and the Transtheoretical Model guided qualitative assessments of the determinants of parents' coping behaviors. Three focus groups with 19 parents of children with eating disorders and 19 semi-structured interviews with experts specializing in eating disorders were conducted. Findings indicate that parents and experts see parents' need for permission to take time for themselves as the main barrier to self-care. The main motivator for parents to engage in coping behaviors is awareness of a connection between self-care and their child's health outcomes. Participant evaluation of six potential messages for main themes and effectiveness revealed that theory-based elements, such as certain processes of change within the Transtheoretical Model, were important to changing health behavior.

Current guidelines for cholesterol treatment emphasize the importance of engaging patients in a risk-benefit discussion prior to initiating statin therapy. Although current risk prediction algorithms are well defined, there is less data on how to communicate with patients about cardiovascular disease risk, benefits of treatment, and possible adverse effects. We propose a four-part model for effective shared decision-making: 1) Assessing patient priorities, perceived risk, and prior experience with cardiovascular risk reduction; 2) Arriving at a recommendation for therapy based on the patient's risk of disease, guideline recommendations, new clinical trial data, and patient preferences; 3) Communicating this recommendation along with risks, benefits, and alternatives to therapy following best practices for discussing numeric risk; and 4) Arriving at a shared decision with the patient with ongoing reassessment as risk factors and patient priorities change.

Microblogging as an extension of science reporting.

PubMed

Büchi, Moritz

2017-11-01

Mass media have long provided general publics with science news. New media such as Twitter have entered this system and provide an additional platform for the dissemination of science information. Based on automated collection and analysis of >900 news articles and 70,000 tweets, this study explores the online communication of current science news. Topic modeling (latent Dirichlet allocation) was used to extract five broad themes of science reporting: space missions, the US government shutdown, cancer research, Nobel Prizes, and climate change. Using content and network analysis, Twitter was found to extend public science communication by providing additional voices and contextualizations of science issues. It serves a recommender role by linking to web resources, connecting users, and directing users' attention. This article suggests that microblogging adds a new and relevant layer to the public communication of science.

Protection motivation theory and stages of change in sun protective behavior.

PubMed

Prentice-Dunn, Steven; McMath, Ben F; Cramer, Robert J

2009-03-01

This study examined the usefulness of the stage of change model and protection motivation theory (PMT) in creating brief persuasive appeals to promote healthy sun-behavior. College women (N = 254) read one of four essays that manipulated the level of threat and coping appraisal. The transition from the precontemplation to contemplation stage was promoted by threat appraisal information, but transition from contemplation to the preparation stage occurred only when individuals were provided with both high threat and high coping information. Thus, brief communications based on PMT may create attitudes leading to behavior change when later, more intensive, interventions are introduced.

Managing the Delivery of Health Care: What Can Health Care Learn From the Business Community?

2015-08-01

The passage of the Patient Protection and Affordable Care Act in March 2010 has resulted in dramatic changes to the delivery of health care in the United States toward a value-based system. While this is a significant change from the previous model, it presents an opportunity for high-quality health care providers to improve patient outcomes while also increasing revenue. However, those that lack a clear strategy to effectively implement change and communicate the increased value to the patients likely will suffer, regardless of how successful or prestigious they seem today.

Does Naming Therapy Make Ordering in a Restaurant Easier? Dynamics of Co-Occurring Change in Cognitive-Linguistic and Functional Communication Skills in Aphasia

2017-01-01

Purpose This study was conducted to investigate the static and dynamic relationships between impairment-level cognitive-linguistic abilities and activity-level functional communication skills in persons with aphasia (PWA). Method In Experiment 1, a battery of standardized assessments was administered to a group of PWA (N = 72) to examine associations between cognitive-linguistic ability and functional communication at a single time point. In Experiment 2, impairment-based treatment was administered to a subset of PWA from Experiment 1 (n = 39) in order to examine associations between change in cognitive-linguistic ability and change in function and associations at a single time point. Results In both experiments, numerous significant associations were found between scores on tests of cognitive-linguistic ability and a test of functional communication at a single time point. In Experiment 2, significant treatment-induced gains were seen on both types of measures in participants with more severe aphasia, yet cognitive-linguistic change scores were not significantly correlated with functional communication change scores. Conclusions At a single time point, cognitive-linguistic and functional communication abilities are associated in PWA. However, although changes on standardized assessments reflecting improvements in both types of skills can occur following an impairment-based therapy, these changes may not be significantly associated with each other.

The current network society, with its primacy of information and communication technologies, is challenging the higher education model. The needs and expectations of today's students differ from those of students in the past, and educational practices should adapt to modern times. But what changes will we see in the relationship between societal…

Autism spectrum disorder (ASD) is a neurodevelopmental disorder with social communication deficits as one of the core symptoms. Recently, a five-level model for the social communication has been proposed in which white matter tracts corresponding to each level of the model are identified. Given that the model for social communication subserves social language functions, we hypothesized that the tract integrity of the model for social communication may be reduced in ASD, and the reduction may be related to social communication deficits. Sixty-two right-handed boys with ASD and 55 typically developing (TD) boys received clinical evaluations, intelligence tests, the Social Communication Questionnaire (SCQ), and MRI scans. Generalized fractional anisotropy (GFA) was measured by diffusion spectrum imaging to indicate the microstructural integrity of the tracts for each level of the social communication model. Group difference in the tract integrity and its relationship with the SCQ subscales of social communication and social interaction were investigated. We found that the GFA values of the superior longitudinal fasciculus III (SLF III, level 1) and the frontal aslant tracts (FAT, level 2) were decreased in ASD compared to TD. Moreover, the GFA values of the SLF III and the FAT were associated with the social interaction subscale in ASD. The tract integrity of the model for social communication is reduced in ASD, and the reduction is associated with impaired social interaction. Our results support that reduced tract integrity of the model for social communication might be a neural substrate of social communication deficits in ASD. © 2016 Association for Child and Adolescent Mental Health.

Translating climate change effects on species into everyday language: an example of more driving and less fishing

Climate science is a complex issue, and we argue that when communicating potential responses of vegetation, fish, and wildlife to nonscientists, creative thinking with respect to the currency of communication will facilitate discussions between scientists, policy makers, and the public. We posit that with some additional thought and relatively simple summaries, the responses of fish and other species to climate change can be translated into everyday language that will facilitate climate science communication. Although such translations are rare, one example of this type of creativity is the translation from changes in habitat suitability for tree species to potential reductions in maple syrup production (West over 2012), which is arguably more interesting and understandable for the general public. Similar translations could be especially important for communicating climate change effects on game fish and other species that are socially and economically important to large groups of people. We demonstrate this translation by communicating the potential effects of climate change on the distribution of a coldwater fish species, the eastern Brook Trout Salvelinus fontinalis. Rather than communicating the potential forecasted contraction of the Brook Trout's distribution in terms of habitat loss, we report the predicted increases in the driving distance to streams likely offering Brook Trout angling opportunities under a climate change scenario. Travel costs based on distance have been widely used to value ecosystem services such as angling under climate change scenarios (e.g., Pendleton and Mendelsohn 1998; Mendelsohn and Markowski 1999; Ahn et al. 2000) but, to the best of our knowledge, have not been used for communicating potential changes to the public despite the intrinsic link to everyday life.

Nursing home culture change is becoming more prevalent, and research has demonstrated its benefits for nursing home residents and staff-but little is known about the role of nursing home administrators in culture change implementation. The purpose of this study was to determine what barriers nursing home administrators face in implementing culture change practices, and to identify the strategies used to overcome them. The authors conducted in-depth individual interviews with 64 administrators identified through a nationally representative survey. Results showed that a key barrier to culture change implementation reported by administrators was staff, resident, and family member resistance to change. Most nursing home administrators stressed the importance of using communication, education and training to overcome this resistance. Themes emerging around the concepts of communication and education indicate that these efforts should be ongoing, communication should be reciprocal, and that all stakeholders should be included.

In the wake of the HIV and AIDS pandemic, health communication has played an important role in social and behavior change in HIV prevention and treatment efforts. Despite this significant role, it is not always clear how health communication influences individuals and communities to facilitate social and behavior change. Guided predominantly by Lewin's theory of change in the context of complexity thinking, and supported by qualitative evidence from Soul City Institute's midterm evaluation of the OneLove multimedia campaign in 9 southern African countries, this article illustrates how carefully designed health edutainment communication materials facilitate drivers of social and behavior change. Thus, researched and theory-based health communication aimed at behavior and social change remains an important pillar in HIV prevention and treatment, where personal and social agency remain key.
