    Background: More than 5 years ago, the Blueprint for Pharmacy developed a plan for transitioning pharmacy practice toward more patient-centred care. Much of the strategy for change involves communicating the new vision. Objective: To evaluate the communication of the Vision for Pharmacy by the organizations and corporations that signed the Blueprint for Pharmacy’s Commitment to Act. Methods: The list of 88 signatories of the Commitment to Act was obtained from the Blueprint for Pharmacy document. The website of each of these signatories was searched for all references to the Blueprint for Pharmacy or Vision for Pharmacy. Each of the identified references was then analyzed using summative content analysis. Results: A total of 934 references were identified from the webpages of the 88 signatories. Of these references, 549 were merely links to the Blueprint for Pharmacy’s website, 350 of the references provided some detailed information about the Blueprint for Pharmacy and only 35 references provided any specific plans to transition pharmacy practice. Conclusion: Widespread proliferation of the Vision for Pharmacy has not been achieved. One possible explanation for this is that communication of the vision by the signatories has been incomplete. To ensure the success of future communications, change leaders must develop strategies that consider how individual pharmacists and pharmacies understand the message. PMID:24660012

    A method for passing remote messages in a parallel computer system formed as a network of interconnected compute nodes includes that a first compute node (A) sends a single remote message to a remote second compute node (B) in order to control the remote second compute node (B) to send at least one remote message. The method includes various steps including controlling a DMA engine at first compute node (A) to prepare the single remote message to include a first message descriptor and at least one remote message descriptor for controlling the remote second compute node (B) to send at least one remote message, including putting the first message descriptor into an injection FIFO at the first compute node (A) and sending the single remote message and the at least one remote message descriptor to the second compute node (B).

    Warning messages transmitted to populations at risk from an accidental release of chemical agent must be carefully designed to maximize appropriate responses from affected publics. This guide develops an approach for preparing Emergency Broadcast System (EBS) messages for the Chemical Stockpile Emergency Preparedness Program (CSEPP). Sample messages illustrate the application of this approach. While the sample messages do not cover every emergency situation, the texts are generic in that accident and location specific factors can be incorporated into the final message developed by local emergency planners. Thus they provide a starting point, not an end product, for emergency planners.

  8. Message passing in PUMA

    Maccabe, A.B. |; Wheat, S.R.

    1993-05-01

    This paper provides an overview of the message passing primitives provided by PUMA (Performance-oriented, User-managed Messaging Architecture). Message passing in PUMA is based on the concept of a portal--an opening in the address space of an application process. Once an application process has established a portal, other processes can write values into the memory associated with the portal using a simple send operation. Because messages are written directly into the address space of the receiving process, there is not need to buffer messages in the PUMA kernel. This simplifies the design of the kernel, increasing its reliability and portability. Moreover, because messages are mapped directly into the address space of the application process, the application can manage the messages that it receives without needing direct support from the kernel.

    I work directly with the System Monitoring and Control (SMC) software engineers who develop, test and release custom and commercial software in support of the Kennedy Space Center Spaceport Command and Control System. (SCCS). SMC uses Commercial Off-The-Shelf (COTS) Enterprise Management Systems (EMS) software which provides a centralized subsystem for configuring, monitoring, and controlling SCCS hardware and software used in the Control Rooms. There are multiple projects being worked on using the COTS EMS software. I am currently working with the HP Operations Manager for UNIX (OMU) software which allows Master Console Operators (MCO) to access, view and interpret messages regarding the status of the SCCS hardware and software. The OMU message browser gets cluttered with messages which can make it difficult for the MCO to manage. My main project involves determining ways to reduce the number of messages being displayed in the OMU message browser. I plan to accomplish this task in two different ways: (1) by correlating multiple messages into one single message being displayed and (2) to create policies that will determine the significance of each message and whether or not it needs to be displayed to the MCO. The core idea is to lessen the number of messages being sent to the OMU message browser so the MCO can more effectively use it.

    Since ancient times, steganography, the art of concealing information, has largely relied on secret inks as a tool for hiding messages. However, as the methods for detecting these inks improved, the use of simple and accessible chemicals as a means to secure communication was practically abolished. Here, we describe a method that enables one to conceal multiple different messages within the emission spectra of a unimolecular fluorescent sensor. Similar to secret inks, this molecular-scale messaging sensor (m-SMS) can be hidden on regular paper and the messages can be encoded or decoded within seconds using common chemicals, including commercial ingredients that can be obtained in grocery stores or pharmacies. Unlike with invisible inks, however, uncovering these messages by an unauthorized user is almost impossible because they are protected by three different defence mechanisms: steganography, cryptography and by entering a password, which are used to hide, encrypt or prevent access to the information, respectively.

Sources d’information Le DSM-V, publié par l’American Psychiatric Association en mai 2013, énonce de nouveaux critères diagnostiques du TSA. Le cadre CanMEDS-MF du Collège des médecins de famille du Canada fournit un plan d’orientation pour la prise en charge complexe du TSA. Nous avons utilisé des données recueillies par le Centers for Disease Control and Prevention afin de déterminer la prévalence du TSA, ainsi que la revue systématique et méta-analyse détaillée effectuée par le National Institute for Health and Care Excellence du R.-U. pour ses lignes directrices sur le TSA dans le but d’évaluer les données probantes issues de plus de 100 interventions. Message principal Selon les données du Centers for Disease Control and Prevention, la prévalence du TSA se chiffrait à 1 sur 88 en 2008 aux États-Unis. La classification du TSA dans la quatrième édition du DSM incluait l’autisme, le syndrome d’Asperger, le trouble envahissant du développement et le trouble désintégratif de l’enfance. La dernière révision du DSM-V réunit tous ces troubles sous la mention TSA, avec différents niveaux de sévérité. La prise en charge du TSA est complexe; elle exige les efforts d’une équipe multidisciplinaire ainsi que des soins continus. Les rôles CanMEDS-MF fournissent un cadre de prise en charge. Conclusion Les médecins de famille sont au cœur de l’équipe de soins multidisciplinaire pour le TSA, et le cadre CanMEDS-MF tient lieu de plan détaillé pour guider la prise en charge d’un enfant atteint de TSA et aider la famille de cet enfant.

    SIP is a general-purpose application layer protocol which is able to establish sessions between two or more parties. These sessions are mainly telephone calls and multimedia conferences. However it can be used for other purposes like instant messaging and presence service. SIP has a very important role in mobile communication as more and more communicating applications are going mobile. In this paper we would like to show how SIP can be used for instant messaging purposes.

    CONVERGENCE is a French multi-partner national project designed to gather HPC and informatics expertise to innovate in the context of running French climate models with differing grids and at differing resolutions. Efficient and reliable execution of these models and the management and dissemination of model output (data and meta-data) are just some of the complexities that CONVERGENCE aims to resolve. The Institut Pierre Simon Laplace (IPSL) is responsible for running climate simulations upon a set of heterogenous HPC environments within France. With heterogeneity comes added complexity in terms of simulation instrumentation and control. Obtaining a global perspective upon the state of all simulations running upon all HPC environments has hitherto been problematic. In this presentation we detail how, within the context of CONVERGENCE, the implementation of the Prodiguer messaging platform resolves complexity and permits the development of real-time applications such as: 1. a simulation monitoring dashboard; 2. a simulation metrics visualizer; 3. an automated simulation runtime notifier; 4. an automated output data & meta-data publishing pipeline; The Prodiguer messaging platform leverages a widely used open source message broker software called RabbitMQ. RabbitMQ itself implements the Advanced Message Queue Protocol (AMPQ). Hence it will be demonstrated that the Prodiguer messaging platform is built upon both open source and open standards.

    The LBNLSecureMessaging application enables collaboration among colocated or geograhically dispersed users by supporting secure synchronous and asynchronous communication. This application is the graphical user interface client that is meant to be used in conjunction with servers (LBNL's PCCEServer and a customized IRC server) to allow group and one-to-one conversations via text-based instant messaging. Conversations may be private (by invitation only) or public (open to any member of a collaboratory group_ and they may be permanentmore » and on-going or temporary and ad hoc. Users may leave notes for other people who are online or offline. By providing presence and awareness information, collaborators can easily locate each other and rendezvous. Written in Java/Swing, this application is cross-platform. To gain access to functionality, users have to be registered with an authorization server (PCCEServer) that maintains an access control list. Thus a collaboration group is comprised of a set of PCCE-registered users. Registered users can log in via either X.509 certificate or a username and password combination. PKI and SSL are used to authenticate servers and clients and to encrypt messages sent over the network. The LBNLSecureMessaging application offers instant messaging capabilities in a secure environment that provides data integrity, privacyk authorization, and authentication.« less

  19. Authentication of quantum messages.

    SciTech Connect

    2001-01-01

    Authentication is a well-studied area of classical cryptography: a sender A and a receiver B sharing a classical private key want to exchange a classical message with the guarantee that the message has not been modified or replaced by a dishonest party with control of the communication line. In this paper we study the authentication of messages composed of quantum states. We give a formal definition of authentication in the quantum setting. Assuming A and B have access to an insecure quantum channel and share a private, classical random key, we provide a non-interactive scheme that both enables A to encrypt and authenticate (with unconditional security) an m qubit message by encoding it into m + s qubits, where the probability decreases exponentially in the security parameter s. The scheme requires a private key of size 2m + O(s). To achieve this, we give a highly efficient protocol for testing the purity of shared EPR pairs. It has long been known that learning information about a general quantum state will necessarily disturb it. We refine this result to show that such a disturbance can be done with few side effects, allowing it to circumvent cryptographic protections. Consequently, any scheme to authenticate quantum messages must also encrypt them. In contrast, no such constraint exists classically: authentication and encryption are independent tasks, and one can authenticate a message while leaving it publicly readable. This reasoning has two important consequences: On one hand, it allows us to give a lower bound of 2m key bits for authenticating m qubits, which makes our protocol asymptotically optimal. On the other hand, we use it to show that digitally signing quantum states is impossible, even with only computational security.

Efficient and reliable execution of these models and the management and dissemination of model output are some of the complexities that CONVERGENCE aims to resolve.At any one moment in time, researchers affiliated with the Institut Pierre Simon Laplace (IPSL) climate modeling group, are running hundreds of global climate simulations. These simulations execute upon a heterogeneous set of French High Performance Computing (HPC) environments. The IPSL's simulation execution runtime libIGCM (library for IPSL Global Climate Modeling group) has recently been enhanced so as to support hitherto impossible realtime use cases such as simulation monitoring, data publication, metrics collection, simulation control, visualizations … etc. At the core of this enhancement is Prodiguer: an AMQP (Advanced Message Queue Protocol) based event driven asynchronous distributed messaging platform. libIGCM now dispatches copious amounts of information, in the form of messages, to the platform for remote processing by Prodiguer software agents at IPSL servers in Paris. Such processing takes several forms: Persisting message content to database(s); Launching rollback jobs upon simulation failure; Notifying downstream applications; Automation of visualization pipelines; We will describe and/or demonstrate the platform's: Technical implementation; Inherent ease of scalability; Inherent adaptiveness in respect to supervising simulations; Web portal receiving simulation notifications in realtime.

  11. Dynamic Message Routing Using Processes

    NASA Astrophysics Data System (ADS)

    Scheibler, Thorsten; Karastoyanova, Dimka; Leymann, Frank

    The Enterprise Service Bus (ESB) is composable middleware that provides applications with services such as message routing and transformation, service composition, dynamic discovery, transactional support, coordination, security features, and others. In an ESB supporting SOAP message exchange, routing algorithms typically follow the sequential SOAP message processing model, where SOAP headers are the main artefacts used to specify the message route and the processing of the payload by intermediaries along that route. This model supports neither alternative nor parallel message routes. In the case of a failing intermediary node this leads to a failure in the message delivery. Moreover, the execution order of services on SOAP message payloads at the intermediaries cannot be prescribed. In this paper, we demonstrate how these deficiencies of the SOAP message processing model can be addressed. We introduce an approach that allows for specifying SOAP message routing logic in terms of BPEL processes. We show that parallel and alternative routes for SOAP messages can be modelled and executed, and the order of services that process a message at intermediaries can be predefined to accommodate the correct processing sequence as required by the concrete application domain. Features like dynamic discovery of services and flexible service composition are leveraged to enable flexible SOAP message routing.

  12. Sequoia Messaging Rate Benchmark

    The purpose of this benchmark is to measure the maximal message rate of a single compute node. The first num_cores ranks are expected to reside on the 'core' compute node for which message rate is being tested. After that, the next num_nbors ranks are neighbors for the first core rank, the next set of num_nbors ranks are neighbors for the second core rank, and so on. For example, testing an 8-core node (num_cores = 8)more » with 4 neighbors (num_nbors = 4) requires 8 + 8 * 4 - 40 ranks. The first 8 of those 40 ranks are expected to be on the 'core' node being benchmarked, while the rest of the ranks are on separate nodes.« less

  14. Framing health messages based on anomalies in time preference.

    PubMed

    Ortendahl, Monica; Fries, James F

    2005-08-01

    Time discounting processes and their effects are increasingly taken into account in health-related decisions. Because these effects have a potentially large impact the characteristics of discounting should also be taken into consideration when framing health messages. Research on the relationship between time and health is discussed with a special focus on discounting biases. The criteria for selection of articles were potential practical application when formulating health messages. Time discounting processes vary with individuals and contexts. Therefore, no single model is expected to describe discounting processes completely. Discounting biases appear more prevalent in health decisions than in economic decisions, even when health and monetary outcomes are matched for utility. Research on decision-making under conditions of uncertainty has documented numerous anomalies of expected utility. Analysis on the anomalies related to intertemporal choice and discounted utility (DU) include the magnitude effect, dynamic inconsistency effect, instant endowment, status quo bias, and sequence effect. Discounting biases in the formulation of preventive health messages are important. The desire for behavioral change in these programs would benefit from considering the psychological factor of discounting. Framing health messages in terms of large, important outcomes or long delays should induce lower implicit discount rates. Framing health messages as losses rather than gains, or as involving a series of outcomes rather than individual outcomes, might similarly lower the implicit discount rate used.

  15. Message Passing on GPUs

    NASA Astrophysics Data System (ADS)

    Stuart, J. A.

    2011-12-01

    This paper explores the challenges in implementing a message passing interface usable on systems with data-parallel processors, and more specifically GPUs. As a case study, we design and implement the ``DCGN'' API on NVIDIA GPUs that is similar to MPI and allows full access to the underlying architecture. We introduce the notion of data-parallel thread-groups as a way to map resources to MPI ranks. We use a method that also allows the data-parallel processors to run autonomously from user-written CPU code. In order to facilitate communication, we use a sleep-based polling system to store and retrieve messages. Unlike previous systems, our method provides both performance and flexibility. By running a test suite of applications with different communication requirements, we find that a tolerable amount of overhead is incurred, somewhere between one and five percent depending on the application, and indicate the locations where this overhead accumulates. We conclude that with innovations in chipsets and drivers, this overhead will be mitigated and provide similar performance to typical CPU-based MPI implementations while providing fully-dynamic communication.

    During the EGEE-III project operational tools such as SAM, Nagios, Gridview, the regional Dashboard and GGUS moved to a communication architecture based on ActiveMQ, an open-source enterprise messaging solution. LHC experiments, in particular ATLAS, developed prototypes of systems using the same messaging infrastructure, validating the system for their use-cases. In this paper we describe the WLCG messaging use cases and outline an improved messaging architecture based on the experience gained during the EGEE-III period. We show how this provides a solid basis for many applications, including the grid middleware, to improve their resilience and reliability.

    2005-01-01

    BACKGROUND Patients want electronic access to providers. Providers fear being overwhelmed by unreimbursed messages. OBJECTIVE Measure the effects of patient-physician web messaging on primary care practices. DESIGN/SETTING Retrospective analysis of 6 case and 9 control internal medicine (IM) and family practice (FP) physicians' message volume, and a survey of 5,971 patients' web messaging with 267 providers and staff in 16 community primary care clinics in the Sacramento, CA region. MEASUREMENTS AND MAIN RESULTS Case telephone volume was 18.2% lower (P =.002) and fell 6.50 times faster than control. Case total telephone plus web message volume was 13.7% lower (P =.025) and fell 5.84 times faster than control. Surveys were responded to by 40.3% (1,743/4,320) of patients and 61.4% (164/267) of providers and staff. Patients were overwhelmingly satisfied and providers and staff were generally satisfied; both found the system easy to use. Patient satisfaction correlated strongly with provider response time (Γ=0.557), and provider/staff satisfaction with computer skills (Γ=0.626) (Goodman-Kruskal Gamma [Γ] measure of ordinal association). CONCLUSIONS Secure web messaging improves on e-mail with encryption, access controls, message templates, customized message and prescription routing, knowledge content, and reimbursement.

  19. The psychology of nutrition messages.

    The purpose of this paper is to explore consumer thinking about nutrition decisions and how firms can use consumers' awareness of the links between nutrients and health generated by public health messages to market products, including ones, which have little nutritional value. We approach this issue by tracking the development of public health messages based on scientific research, dissemination of those messages in the popular press, and use of nutrition claims in food advertisements to assess whether firms are timing the use of nutrition claims to take advantage of heuristic-based decision-making. Our findings suggest that the timing of the development of nutrition information, its dissemination in the press, and use in advertising accords well with a heuristic processing model in which firms take advantage of associations between nutrient information and health in their advertisements. However, the demonstrated relationships may not be causal. Further research will be needed to provide stronger and more comprehensive evidence regarding the proposed message hijacking process. If the message hijacking framework is borne out: (1) simple overall health rating scales could significantly improve consumer decision-making, (2) the impact of misleading advertisements could be mitigated by encouraging a multidimensional view of nutrition, and (3) more intensive regulation of product labeling could limit the impact of hijacked messages. Overall, this paper considers a novel hypothesis about the impact of public health messages on nutrition and health. PMID:19548517

  20. Active messages versus explicit message passing under SUNMOS

    In the past few years much effort has been devoted to finding faster and more convenient ways to exchange data between nodes of massively parallel distributed memory machines. One such approach, taken by Thorsten von Eicken et al. is called Active Messages. The idea is to hide message passing latency and continue to compute while data is being sent and delivered. The authors have implemented Active Messages under SUNMOS for the Intel Paragon and performed various experiments to determine their efficiency and utility. In this paper they concentrate on the subset of the Active Message layer that is used by the implementation of the Split-C library. They compare performance to explicit message passing under SUNMOS and explore new ways to support Split-C without Active Messages. They also compare the implementation to the original one on the Thinking Machines CM-5 and try to determine what the effects of low latency and low band-width versus high latency and high bandwidth are on user codes.

  1. Priority nutrition messages.

    PubMed

    1991-01-01

    The Philippine Food and Nutrition Program deliver priority short, simple, clear, and action filled nutrition messages in different languages and dialects to different audiences. Its 1st priority task is to promote breast feeding. It informs mothers that breast milk is the most nutritious food for infants and that it protects them from infectious diseases. The program also encourages breast feeding as long as possible. If mothers cannot breast feed, they should talk to an infant nutrition expert to help them choose the best formula and learn about proper preparation. A 4-6 month infant needs to begin eating small amounts of semisolid nutritious foods. Moreover these foods must include body building foods, such as meat and eggs, and energy providing foods, such as corn and rice. Mothers must 1st attend to food needs of infants and preschoolers since they are more likely to suffer malnutrition than older children and adults. This is especially important when they suffer from an infection. Specifically, the very young need a variety of foods each day including the vitamin and mineral rich vegetables and fruits. In fact, families should grow their own fruits and vegetables to ensure an adequate supply. Hands must be cleaned with soap and water after defecation and before preparing foods. Mothers should add fats and oils when preparing foods because they provide concentrated energy, fatty acids, and fat soluble vitamins. Pregnant mothers must consume increased amounts of fish, beans, and other body building foods as well as regulating foods (vegetables and fruits). Mothers must also space births. They should weigh children each month to monitor nutritional levels. Moreover they must pay attention to signs indicating inadequate and insufficient food intake e.g., underweight and night blindness.

    Escobar, Rodrigo D.; Akopian, David; Parra-Medina, Deborah; Esparza, Laura

    2013-03-01

    Mobile Health (mHealth) has emerged as a promising direction for delivery of healthcare services via mobile communication devices such as cell phones. Examples include texting-based interventions for chronic disease monitoring, diabetes management, control of hypertension, smoking cessation, monitoring medication adherence, appointment keeping and medical test result delivery; as well as improving patient-provider communication, health information communication, data collection and access to health records. While existing messaging systems very well support bulk messaging and some polling applications, they are not designed for data collection and processing of health research oriented studies. For that reason known studies based on text-messaging campaigns have been constrained in participant numbers. In order to empower healthcare promotion and education research, this paper presents a system dedicated for healthcare research. It is designed for convenient communication with various study groups, feedback collection and automated processing.

  13. Formal Analysis of Message Passing

    NASA Astrophysics Data System (ADS)

    Siegel, Stephen F.; Gopalakrishnan, Ganesh

    The message passing paradigm underlies many important families of programs - for instance programs in the area of high performance computing that support science and engineering research. Unfortunately, very few formal methods researchers are involved in developing formal analysis tools and techniques for message passing programs. This paper summarizes research being done in our groups in support of this area, specifically with respect to the Message Passing Interface. We emphasize the need for specialized varieties of many familiar notions such as deadlock detection, race analysis, symmetry analysis, partial order reduction, static analysis and symbolic reasoning support. Since these issues are harbingers of those being faced in multicore programming, the time is ripe to build a critical mass of researchers working in this area.

    The authors consider the deterministic and random parallel complexity (time and processor) of message decoding: an essential problem in communications systems and translation systems. They present an optimal parallel algorithm to decompose prefix-coded messages and uniquely decipherable-coded messages in O(n/P) time, using O(P) processors (for all P:1 less than or equal toPless than or equal ton/log n) deterministically as well as randomly on the weakest version of parallel random access machines in which concurrent read and concurrent write to a cell in the common memory are not allowed. This is done by reducing decoding to parallel finite-state automata simulation and the prefix sums.

    2008-09-01

    As scholars involved with the Search for Extraterrestrial Intelligence (SETI) have contemplated how we might portray humankind in any messages sent to civilizations beyond Earth, one of the challenges they face is adequately representing the diversity of human cultures. For example, in a 2003 workshop in Paris sponsored by the SETI Institute, the International Academy of Astronautics (IAA) SETI Permanent Study Group, the International Society for the Arts, Sciences and Technology (ISAST), and the John Templeton Foundation, a varied group of artists, scientists, and scholars from the humanities considered how to encode notions of altruism in interstellar messages . Though the group represented 10 countries, most were from Europe and North America, leading to the group's recommendation that subsequent discussions on the topic should include more globally representative perspectives. As a result, the IAA Study Group on Interstellar Message Construction and the SETI Institute sponsored a follow-up workshop in Santa Fe, New Mexico, USA in February 2005. The Santa Fe workshop brought together scholars from a range of disciplines including anthropology, archaeology, chemistry, communication science, philosophy, and psychology. Participants included scholars familiar with interstellar message design as well as specialists in cross-cultural research who had participated in the Symposium on Altruism in Cross-cultural Perspective, held just prior to the workshop during the annual conference of the Society for Cross-cultural Research . The workshop included discussion of how cultural understandings of altruism can complement and critique the more biologically based models of altruism proposed for interstellar messages at the 2003 Paris workshop. This paper, written by the chair of both the Paris and Santa Fe workshops, will explore the challenges of communicating concepts of altruism that draw on both biological

    Résumé Objectif Offrir aux médecins de famille un résumé des recommandations fondées sur les données probantes pour guider les soins aux survivantes traitées pour le cancer du sein. Qualité des données Une recherche documentaire a été effectuée dans MEDLINE entre 2000 et 2016 à l’aide des mots-clés anglais suivants : breast cancer, survivorship, follow-up care, aftercare, guidelines et survivorship care plans, en se concentrant sur la revue des lignes directrices publiées récemment par les organismes nationaux de cancérologie. Les données étaient de niveaux I à III. Message principal Les soins aux survivantes comportent 4 facettes : surveillance et dépistage, prise en charge des effets à long terme, promotion de la santé et coordination des soins. La surveillance des récidives ne se traduit que par une mammographie annuelle, et le dépistage d’autres cancers doit suivre les lignes directrices basées sur la population. La prise en charge des effets à long terme du cancer et de son traitement aborde des problèmes courants tels la douleur, la fatigue, le lymphœdème, la détresse et les effets indésirables des médicaments, de même que les préoccupations à long terme comme la santé du cœur et des os. La promotion de la santé met en relief les bienfaits de l’activité chez les survivantes du cancer, avec l’accent mis sur l’activité physique. Les soins aux survivantes sont de meilleure qualité lorsque divers services et professionnels de la santé participent aux soins, et le médecin de famille joue un rôle important dans la coordination des soins. Conclusion Les médecins de famille sont de plus en plus souvent les principaux fournisseurs de soins de suivi après le traitement du cancer du sein. Le cancer du sein doit être considéré comme une affection médicale chronique, même chez les femmes en rémission, et les patientes profitent de la même approche que celle utilisée pour les autres affections chroniques en

  20. Toward Predicting Popularity of Social Marketing Messages

    Yu, Bei; Chen, Miao; Kwok, Linchi

    Popularity of social marketing messages indicates the effectiveness of the corresponding marketing strategies. This research aims to discover the characteristics of social marketing messages that contribute to different level of popularity. Using messages posted by a sample of restaurants on Facebook as a case study, we measured the message popularity by the number of "likes" voted by fans, and examined the relationship between the message popularity and two properties of the messages: (1) content, and (2) media type. Combining a number of text mining and statistics methods, we have discovered some interesting patterns correlated to "more popular" and "less popular" social marketing messages. This work lays foundation for building computational models to predict the popularity of social marketing messages in the future.

    Instant messaging (IM) is when users communicate instantly via their mobile devices, and it has become one of the most preferred choices of tools to communicate amongst health professions students. The aim of this study was to understand how dental students communicate via IM, faculty members' perspectives on using IM to communicate with students, and whether such tools are useful in the learning environment. After free-associating themes on online communication, two draft topic guides for structured interviews were designed that focussed on mobile device-related communication activities. A total of 20 students and six faculty members at the University of Birmingham School of Dentistry agreed to take part in the interviews. Students were selected from years 1-5 representing each year group. The most preferred communication tools were emails, social networking, and IM. Emails were used for more formal messages, and IM and social networking sites were used for shorter messages. WhatsApp was the most used IM app because of its popular features such as being able to check if recipients have read and received messages and group work. The students reported that changes were necessary to improve their communication with faculty members. The faculty members reported having mixed feelings toward the use of IM to communicate with students. The students wished to make such tools a permanent part of their learning environment, but only with the approval of faculty members. The faculty members were willing to accept IM as a communication tool only if it is monitored and maintained by the university and has a positive effect on learning. PMID:26632303

    1993-06-01

    Information, education, and communication (IEC) programs need to be strengthened to appeal to adolescents, who are increasingly contributing to unwanted pregnancy and are using abortion as a means of birth control. Successful IEC programs have the following characteristics: 1) established communication theories that guide development of materials; 2) a multimedia and a mass media approach to information dissemination, and 3) emphasis on visual displays. The primary emphasis should be on presentation of a concise, clear message with the appropriate visual medium. Many communication specialists in developing countries, however, lack the training to design and use effective IEC software. Designing effective messages involves a process of integrating scientific ideas with artistic appeal. The aim is to stimulate the target audience to change its behavior of life style. The message must be convincing and contain practical and useful information. The IEC Software Design Cycle focuses on analysis and diagnosis, design production, pretesting and modification, and distribution and evaluation. Each of these processes are described. Necessary before any attempt is made is obtaining data on historical, sociocultural, and demographic characteristics, economic activities, health and social services, communication infrastructure, marriage and family life patterns, and decision making systems. Focus group discussions may be used to collect information about the target group. An example is given of the process of development, in a course through the Center or African Family Studies, of a poster about premarital sex directed to 11-16 year olds. On the basis of focus group discussions, it was decided that the message would be to encourage girls to talk with their mothers about family life and premarital sex. The poster was produced with 2 school girls talking in front of the school. The evaluation yielded modifications such as including a school building that resembled actual

    Résumé Objectif Informer les médecins de famille quant à l’efficacité, à l’innocuité, aux effets sur la santé publique et à la rentabilité du vaccin 9-valent contre le virus du papillome humain (VPH). Qualité des données Des articles pertinents publiés dans PubMed jusqu’en mai 2015 ont été examinés et analysés. La plupart des données citées sont de niveau I (essais randomisés et contrôlés et méta-analyses) ou de niveau II (études transversales, cas-témoins et épidémiologiques). Des rapports et recommandations du gouvernement sont aussi cités en référence. Message principal Le vaccin 9-valent contre le VPH, qui offre une protection contre les types 6, 11, 16, 18, 31, 33, 45, 52 et 58 du VPH, est sûr et efficace et réduira encore plus l’incidence des infections à VPH, de même que les cas de cancer lié au VPH. Il peut également protéger indirectement les personnes non immunisées par l’entremise du phénomène d’immunité collective. Un programme d’immunisation efficace peut prévenir la plupart des cancers du col de l’utérus. Les analyses montrent que la rentabilité du vaccin 9-valent chez les femmes est comparable à celle du vaccin quadrivalent original contre le VPH (qui protège contre les types 6, 11, 16 et 18 du VPH) en usage à l’heure actuelle. Toutefois, il faut investiguer plus en profondeur l’utilité d’immuniser les garçons avec le vaccin 9-valent contre le VPH. Conclusion en plus d’être sûr, le vaccin 9-valent protège mieux contre le VPH que le vaccin quadrivalent. Une analyse coûtefficacité en favorise l’emploi, du moins chez les adolescentes. Ainsi, les médecins devraient recommander le vaccin 9-valent à leurs patients plutôt que le vaccin quadrivalent contre le VPH.

    1992-09-01

    Warning messages transmitted to populations at risk from an accidental release of chemical agent must be carefully designed to maximize appropriate responses from affected publics. This guide develops an approach for preparing Emergency Broadcast System (EBS) messages for the Chemical Stockpile Emergency Preparedness Program (CSEPP). Sample messages illustrate the application of this approach. While the sample messages do not cover every emergency situation, the texts are generic in that accident and location specific factors can be incorporated into the final message developed by local emergency planners. Thus they provide a starting point, not an end product, for emergency planners.

    Currently existing message logging protocols demonstrate a classic pessimistic vs. optimistic tradeoff. We show that the optimistic-pessimistic tradeoff is not inherent to the problem of message logging. We construct a message-logging protocol that has the positive features of both optimistic and pessimistic protocol: our protocol prevents orphans and allows simple failure recovery; however, it requires no blocking in failure-free runs. Furthermore, this protocol does not introduce any additional message overhead as compared to one implemented for a system in which messages may be lost but processes do not crash.

The transmission side of the messaging unit, includes switch interface for reading from the memory system when injecting packets into the network.

  13. Asynchronous Message Service Reference Implementation

    NASA Technical Reports Server (NTRS)

    Burleigh, Scott C.

    2011-01-01

    This software provides a library of middleware functions with a simple application programming interface, enabling implementation of distributed applications in conformance with the CCSDS AMS (Consultative Committee for Space Data Systems Asynchronous Message Service) specification. The AMS service, and its protocols, implement an architectural concept under which the modules of mission systems may be designed as if they were to operate in isolation, each one producing and consuming mission information without explicit awareness of which other modules are currently operating. Communication relationships among such modules are self-configuring; this tends to minimize complexity in the development and operations of modular data systems. A system built on this model is a society of generally autonomous, inter-operating modules that may fluctuate freely over time in response to changing mission objectives, modules functional upgrades, and recovery from individual module failure. The purpose of AMS, then, is to reduce mission cost and risk by providing standard, reusable infrastructure for the exchange of information among data system modules in a manner that is simple to use, highly automated, flexible, robust, scalable, and efficient. The implementation is designed to spawn multiple threads of AMS functionality under the control of an AMS application program. These threads enable all members of an AMS-based, distributed application to discover one another in real time, subscribe to messages on specific topics, and to publish messages on specific topics. The query/reply (client/server) communication model is also supported. Message exchange is optionally subject to encryption (to support confidentiality) and authorization. Fault tolerance measures in the discovery protocol minimize the likelihood of overall application failure due to any single operational error anywhere in the system. The multi-threaded design simplifies processing while enabling application nodes to

  15. Regulatory fit messages and physical activity motivation.

    PubMed

    Pfeffer, Ines

    2013-04-01

    Targeted communication about health behaviors seems to be more effective than mass communication in which undifferentiated audiences receive identical messages. Regulatory focus is psychological variable that can be used to build two target groups: promotion-focused or prevention-focused people. It is hypothesized that targeting messages to an individual's regulatory focus creates regulatory fit and is more successful to promote a physically active lifestyle than nonfit messages. Two different print messages promoting a physically active lifestyle derived from regulatory focus theory (promotion message vs. prevention message) were randomly assigned to N = 98 participants after measuring their regulatory focus. It was examined whether regulatory fit between the regulatory focus and the assigned print message would lead to more positive evaluations in the dependent variables inclination toward the message (preference for the message), intention to perform the behavior, prospective and retrospective feelings associated with the behavior (positive and negative), and perceived value of the behavior directly after reading the message. Hierarchical linear regression analyses revealed that regulatory fit led to stronger intentions in the prevention-message condition and more prospective positive and retrospective positive feelings associated with the behavior in the promotion-message condition in contrast to the nonfit conditions. Prospective positive feelings associated with the behavior mediated the effect of regulatory fit on intention. The results partly provided support for the regulatory fit concept. Matching print messages to the regulatory focus of individuals seems to be a useful approach to enhance physical activity motivation. Future studies should include an objective measure of physical activity behavior.

  16. Optimal message log reclamation for uncoordinated checkpointing

    Uncoordinated checkpointing for message-passing systems allows maximum process autonomy and general nondeterministic execution, but suffers from potential domino effect and the large space overhead for maintaining checkpoints and message logs. Traditionally, it has been assumed that only obsolete checkpoints and message logs before the global recovery line can be garbage-collected. Recently, an approach to identifying all garbage checkpoints based on recovery line transformation and decomposition has been developed. We show in this paper that the same approach can be applied to the problem of identifying all garbage message logs for systems requiring message logging to record in-transit messages. Communication trace-driven simulation for several parallel programs is used to evaluate the proposed algorithm.

    Living with diabetes makes great educational demands on a family. We have tested the feasibility of using the mobile phone short message service (SMS) for reaching people with diabetes information. We also assessed user satisfaction and perceived pros and cons of the medium through interviews. Eleven parents of children with type 1 diabetes received messages for 11 weeks. The parents were positive about the system and said that they would like to continue to use it. The pop-up reminding effect of SMS messages in busy everyday life was noted as positive. Some parents experienced the messages as somewhat intrusive, arriving too often and at inconvenient times. The parents also noted the potential of the messages to facilitate communication with their adolescent children. The inability to store all of the messages or to print them out were seen as major disadvantages. Overall, the SMS seems to hold promise as means of delivering diabetes information.

    In 2010, the U.S. National Weather Service (NWS) funded a three year project to integrate social science into their Tsunami Program. One of three primary requirements of the grant was to make improvements to tsunami warning messages of the NWS' two Tsunami Warning Centers- the West Coast/Alaska Tsunami Warning Center (WCATWC) in Palmer, Alaska and the Pacific Tsunami Warning Center (PTWC) in Ewa Beach, Hawaii. We conducted focus group meetings with a purposive sample of local, state and Federal stakeholders and emergency managers in six states (AK, WA, OR, CA, HI and NC) and two US Territories (US Virgin Islands and American Samoa) to qualitatively asses information needs in tsunami warning messages using WCATWC tsunami messages for the March 2011 Tohoku earthquake and tsunami event. We also reviewed research literature on behavioral response to warnings to develop a tsunami warning message metric that could be used to guide revisions to tsunami warning messages of both warning centers. The message metric is divided into categories of Message Content, Style, Order and Formatting and Receiver Characteristics. A message is evaluated by cross-referencing the message with the operational definitions of metric factors. Findings are then used to guide revisions of the message until the characteristics of each factor are met. Using findings from this project and findings from a parallel NWS Warning Tiger Team study led by T. Nicolini, the WCATWC implemented the first of two phases of revisions to their warning messages in November 2012. A second phase of additional changes, which will fully implement the redesign of messages based on the metric, is in progress. The resulting messages will reflect current state-of-the-art knowledge on warning message effectiveness. Here we present the message metric; evidence-based rational for message factors; and examples of previous, existing and proposed messages.

  19. Optimal message log reclamation for independent checkpointing

    Wang, Yi-Min; Fuchs, W. Kent

    1993-01-01

    Independent (uncoordinated) check pointing for parallel and distributed systems allows maximum process autonomy but suffers from possible domino effects and the associated storage space overhead for maintaining multiple checkpoints and message logs. In most research on check pointing and recovery, it was assumed that only the checkpoints and message logs older than the global recovery line can be discarded. It is shown how recovery line transformation and decomposition can be applied to the problem of efficiently identifying all discardable message logs, thereby achieving optimal garbage collection. Communication trace-driven simulation for several parallel programs is used to show the benefits of the proposed algorithm for message log reclamation.

    Parent-child communication about sex is an important proximal reproductive health outcome. But while campaigns to promote it such as the Parents Speak Up National Campaign (PSUNC) have been effective, little is known about how messages influence parental cognitions and behavior. This study examines which message features explain responses to sexual communication messages. We content analyzed 4 PSUNC ads to identify specific, measurable message and advertising execution features. We then develop quantitative measures of those features, including message strategies, marketing strategies, and voice and other stylistic features, and merged the resulting data into a dataset drawn from a national media tracking survey of the campaign. Finally, we conducted multivariable logistic regression models to identify relationships between message content and ad reactions/receptivity, and between ad reactions/receptivity and parents' cognitions related to sexual communication included in the campaign's conceptual model. We found that overall parents were highly receptive to the PSUNC ads. We did not find significant associations between message content and ad reactions/receptivity. However, we found that reactions/receptivity to specific PSUNC ads were associated with increased norms, self-efficacy, short- and long-term expectations about parent-child sexual communication, as theorized in the conceptual model. This study extends previous research and methods to analyze message content and reactions/receptivity. The results confirm and extend previous PSUNC campaign evaluation and provide further evidence for the conceptual model. Future research should examine additional message content features and the effects of reactions/receptivity.

    Online social networking sites represent significant new opportunities for Internet advertisers. However, results based on the real world cannot be generalized to all virtual worlds. In this research, the moderating effects of need for cognition (NFC) and knowledge were applied to examine the impact of message framing on attitudes toward social networking sites. A total of 216 undergraduates participated in the study. Results reveal that for social networking sites, while high-NFC individuals form more favorable attitudes toward negatively framed messages than positively framed messages, low-NFC individuals form more favorable attitudes toward positively framed messages than negatively framed messages. In addition, low-knowledge individuals demonstrate more favorable attitudes toward negatively framed messages than positively framed messages; however, the framing effect does not differentially affect the attitudes of high-knowledge individuals. Furthermore, the framing effect does not differentially affect the attitudes of high-NFC individuals with high knowledge. In contrast, low-NFC individuals with low knowledge hold more favorable attitudes toward positively framed messages than negatively framed messages. PMID:23786169

Qualité des données Les recommandations sont classées comme étant fondées sur des données probantes fortes, acceptables ou faibles (conflictuelles ou insuffisantes), selon les classifications adoptées par le Groupe d’étude canadien sur les soins de santé préventifs. Message principal Le dépistage de la dyslipidémie comme facteur de risque de coronaropathie et la prescription de médicaments hypolipidémiants sont des activités importantes en soins primaires. De récentes données probantes remettent en question la nécessité d’être à jeun pour la mesure des lipides. Dans des études sur la population, le cholestérol total, le cholestérol à lipoprotéines de haute densité et le cholestérol à lipoprotéines autres qu’à haute densité variaient tous d’en moyenne 2 % à jeun. Pour un dépistage de routine, la mesure du cholestérol sans être à jeun est maintenant une option de rechange raisonnable à l’analyse à jeun. Pour les patients diabétiques, l’exigence d’être à jeun peut représenter un important problème de sécurité en raison des possibilités d’hypoglycémie. Pour la surveillance des triglycérides et du cholestérol à lipoprotéines de basse densité chez les patients qui prennent des médicaments hypolipidémiants, le jeûne devient important. Conclusion Être à jeun pour la détermination routinière des niveaux lipidiques est largement inutile et il est improbable que le jeûne influence la stratification du risque clinique chez le patient, tandis que la mesure sans être à jeun pourrait améliorer l’observance par le patient et sa sécurité.

    In large-scale computing systems, the sheer volume of log data generated presents daunting challenges for debugging and monitoring of these systems. The Oak Ridge Leadership Computing Facility s premier simulation platform, the Cray XT5 known as Jaguar, can generate a few hundred thousand log entries in less than a minute for many system level events. Determining the root cause of such system events requires analyzing and interpretation of a large number of log messages. Most often, the log messages are best understood when they are interpreted collectively rather than individually. In this paper, we present our approach to interpreting log messages by identifying their commonalities and grouping them into clusters. Given a set of log messages within a time interval, we group the messages based on source, target, and/or error type, and correlate the messages with hardware and application information. We monitor the Lustre log messages in the XT5 console log and show that such grouping of log messages assists in detecting the source of system events. By intelligent grouping and correlation of events in the log, we are able to provide system administrators with meaningful information in a concise format for root cause analysis.

    1993-04-01

    The Area Message Service (AMS) is a TCP/IP based messaging service currently in use at SLAC. A number of projects under development here at SLAC require and application level interface to the 4.3BSD UNIX socket level communications functions using TCP/IP over ethernet. AMS provides connection management, solicited message transfer, unsolicited message transfer, and asynchronous notification of pending messages. AMS is written completely in ANSI `C` and is currently portable over three hardware/operating system/network manager platforms, VAX/VMS/Multinet, PC/MS-DOS/Pathworks, VME 68K/pSOS/pNA. The basic architecture is a client-server connection where either end of the interface may be the server. This allows for connections and data flow to be initiated from either end of the interface. Included in the paper are details concerning the connection management, the handling of the multi-platform code, and the implementation process.

    2015-01-01

    Messages are central to human social experience, and pose key conceptual and methodological challenges in the study of communication. In response to these challenges, we outline a systematic approach to conceptualizing, operationalizing, and analyzing messages. At the conceptual level, we distinguish between two core aspects of messages: message variability (the defined and operationalized features of messages) and message heterogeneity (the undefined and unmeasured features of messages), and suggest preferred approaches to defining message variables. At the operational level, we identify message sampling, selection, and research design strategies responsive to issues of message variability and heterogeneity in experimental and survey research. At the analytical level, we highlight effective techniques to deal with message variability and heterogeneity. We conclude with seven recommendations to increase rigor in the study of communication through appropriately addressing the challenges presented by messages. PMID:26681816

  20. Message Passing Framework for Globally Interconnected Clusters

    In prevailing technology trends it is apparent that the network requirements and technologies will advance in future. Therefore the need of High Performance Computing (HPC) based implementation for interconnecting clusters is comprehensible for scalability of clusters. Grid computing provides global infrastructure of interconnecting clusters consisting of dispersed computing resources over Internet. On the other hand the leading model for HPC programming is Message Passing Interface (MPI). As compared to Grid computing, MPI is better suited for solving most of the complex computational problems. MPI itself is restricted to a single cluster. It does not support message passing over the internet to use the computing resources of different clusters in an optimal way. We propose a model that provides message passing capabilities between parallel applications over the internet. The proposed model is based on Architecture for Java Universal Message Passing (A-JUMP) framework and Enterprise Service Bus (ESB) named as High Performance Computing Bus. The HPC Bus is built using ActiveMQ. HPC Bus is responsible for communication and message passing in an asynchronous manner. Asynchronous mode of communication offers an assurance for message delivery as well as a fault tolerance mechanism for message passing. The idea presented in this paper effectively utilizes wide-area intercluster networks. It also provides scheduling, dynamic resource discovery and allocation, and sub-clustering of resources for different jobs. Performance analysis and comparison study of the proposed framework with P2P-MPI are also presented in this paper.

  1. Communicating Concepts about Altruism in Interstellar Messages

    Vakoch, Douglas A.

    2002-01-01

    This project identifies key principles of altruism that can be translated into interstellar messages for communication with extraterrestrial intelligence. The message contents will focus specifically on the evolution of altruism, drawing on recent insights in evolutionary biology, with particular emphasis on sociobiological accounts of kin selection and reciprocal altruism. This focus on altruism for message contents has several advantages. First, the subject can be translated into interstellar messages both via an existing formal interstellar language and via pictorial messages. For example, aspects of reciprocal altruism can be described through mathematical modeling, such as game theoretic approaches, which in turn can be described readily in the interstellar language Lincos. Second, concentrating on altruism as a message content may facilitate communications with extraterrestrial intelligence. Some scientists have argued that humans may be expected to communicate something about their moral status and development in an exchange with extraterrestrials. One of the most salient ways that terrestrial and extraterrestrial civilizations might be expected to evaluate one another is in terms of ethical motivations. Indeed, current search strategies assume some measure of altruism on the part of transmitting civilizations; with no guarantee of a response, the other civilization would be providing information to us with no direct payoff. Thus, concepts about altruism provide an appropriate content for interstellar messages, because the concepts themselves might be understood by extraterrestrial civilizations.

  2. A New Look at Reweighted Message Passing.

    PubMed

    Kolmogorov, Vladimir

    2015-05-01

    We propose a new family of message passing techniques for MAP estimation in graphical models which we call Sequential Reweighted Message Passing (SRMP). Special cases include well-known techniques such as Min-Sum Diffusion (MSD) and a faster Sequential Tree-Reweighted Message Passing (TRW-S). Importantly, our derivation is simpler than the original derivation of TRW-S, and does not involve a decomposition into trees. This allows easy generalizations. The new family of algorithms can be viewed as a generalization of TRW-S from pairwise to higher-order graphical models. We test SRMP on several real-world problems with promising results.

  3. When message-frame fits salient cultural-frame, messages feel more persuasive.

    PubMed

    2010-03-01

    The present study examines the persuasive effects of tailored health messages comparing those tailored to match (versus not match) both chronic cultural frame and momentarily salient cultural frame. Evidence from two studies (Study 1: n = 72 European Americans; Study 2: n = 48 Asian Americans) supports the hypothesis that message persuasiveness increases when chronic cultural frame, health message tailoring and momentarily salient cultural frame all match. The hypothesis was tested using a message about health risks of caffeine consumption among individuals prescreened to be regular caffeine consumers. After being primed for individualism, European Americans who read a health message that focused on the personal self were more likely to accept the message-they found it more persuasive, believed they were more at risk and engaged in more message-congruent behaviour. These effects were also found among Asian Americans who were primed for collectivism and who read a health message that focused on relational obligations. The findings point to the importance of investigating the role of situational cues in persuasive effects of health messages and suggest that matching content to primed frame consistent with the chronic frame may be a way to know what to match messages to.

    2012-05-01

    We introduce two types of message passing algorithms for quantified Boolean formulas (QBF). The first type is a message passing based heuristics that can prove unsatisfiability of the QBF by assigning the universal variables in such a way that the remaining formula is unsatisfiable. In the second type, we use message passing to guide branching heuristics of a Davis-Putnam-Logemann-Loveland (DPLL) complete solver. Numerical experiments show that on random QBFs our branching heuristics give robust exponential efficiency gain with respect to state-of-the-art solvers. We also manage to solve some previously unsolved benchmarks from the QBFLIB library. Apart from this, our study sheds light on using message passing in small systems and as subroutines in complete solvers.

    PubMed

    Richards, Adam S; Banas, John A

    2015-01-01

    This investigation examined the possibility of decreasing psychological reactance to health campaigns through the use of inoculation messages. It was hypothesized that an inoculation message, which forewarned of the potential of subsequent reactance, would decrease participants' likelihood of reacting negatively to a freedom-threatening message aimed to reduce excessive alcohol consumption. Participants (N = 275) who were inoculated against potential reactance felt less threatened and experienced less reactance compared to those who did not read an inoculation message. Structural equation modeling showed that inoculation indirectly predicted lower intention to drink alcohol via the theorized mediated reactance process. This research suggests that it is possible to inoculate against self-generated cognitions that might otherwise lead toward negative health behaviors.

    Morrone, Michele; Tres, Alejandra; Aronin, Ruben

    2005-01-01

    The Centers for Disease Control and Prevention supported research coordinated by the Association of Environmental Health Academic Programs (AEHAP) for the purpose of developing effective messages about environmental health. The purpose of these messages would be to increase the visibility of the environmental health profession and improve the public's awareness and understanding of the role played by the profession in protecting the public's health. To accomplish this task, AEHAP first collaborated with a marketing team to develop initial test messages. The core message revolved around five major themes: effects of pollution, susceptible populations, economics and prevention, homeland security, and specific environmental health issues. The draft messages were tested in three focus group settings: 1) policy makers, 2) environmental health professionals, and 3) the general public. This paper reports a finding that there is a perceptual gap among environmental health professionals, policy makers, and the public. This gap is part of why there is a compelling need for the environmental health community to develop and disseminate more effective messages about the profession.

    Résumé Objectif Explorer les raisons pour lesquelles la perte de poids à long terme échoue la plupart du temps et évaluer les conséquences de diverses trajectoires pondérales, y compris la stabilité, la perte et le gain. Source des données Les études qui évaluent les paramètres pondéraux dans la population sont en majorité observationnelles. Des données probantes de niveau I ont été publiées pour évaluer l’influence des interventions relatives au poids sur la mortalité et la qualité de vie. Message principal Seulement un petit pourcentage des personnes qui désirent perdre du poids réussissent à le faire de manière durable. La mortalité est la plus faible chez les personnes se situant dans la catégorie de poids élevé-normal et surpoids. La trajectoire pondérale la plus sécuritaire est la stabilité du poids avec une optimisation de la condition physique et métabolique. Il est démontré que la mortalité est plus faible chez les personnes ayant des comorbidités reliées à l’obésité si elles perdent du poids. Il est aussi établi que la qualité de vie sur le plan de la santé est meilleure chez les personnes obèses qui perdent du poids. Par contre, la perte de poids chez une personne obèse autrement en santé est associée à une mortalité accrue. Conclusion La perte de poids est recommandable seulement chez les personnes qui ont des comorbidités reliées à l’obésité. Les personnes obèses en santé qui veulent perdre du poids devraient être informées qu’il peut y avoir des risques à le faire. Une stratégie qui se traduit par un indice de masse corporelle stable avec une condition physique et métabolique optimisée, peu importe le poids, est l’option d’intervention la plus sécuritaire en ce qui concerne le poids.

    2015-04-01

    At any one moment in time, researchers affiliated with the Institut Pierre Simon Laplace (IPSL) climate modeling group, are running hundreds of global climate simulations. These simulations execute upon a heterogeneous set of High Performance Computing (HPC) environments spread throughout France. The IPSL's simulation execution runtime is called libIGCM (library for IPSL Global Climate Modeling group). libIGCM has recently been enhanced so as to support realtime operational use cases. Such use cases include simulation monitoring, data publication, environment metrics collection, automated simulation control … etc. At the core of this enhancement is the Prodiguer messaging platform. libIGCM now emits information, in the form of messages, for remote processing at IPSL servers in Paris. The remote message processing takes several forms, for example: 1. Persisting message content to database(s); 2. Notifying an operator of changes in a simulation's execution status; 3. Launching rollback jobs upon simulation failure; 4. Dynamically updating controlled vocabularies; 5. Notifying downstream applications such as the Prodiguer web portal; We will describe how the messaging platform has been implemented from a technical perspective and demonstrate the Prodiguer web portal receiving realtime notifications.

  19. Emotional flow in persuasive health messages.

    PubMed

    Nabi, Robin L

    2015-01-01

    Overwhelmingly, the literature on the persuasive influence of emotions has focused on individual emotions, fear in particular, though some recent attention has been given to mixed emotions in persuasive appeals. Building on this newer wave of research, this article argues that instead of focusing on singular emotional states or collections of emotions evoked by a message, it might prove valuable to explore the flow, or evolution, of emotional experience over the course of exposure to a health message. The article offers a brief introduction to the concept of emotion, followed by a review of the state of the literature on the use of emotion in health messages. The concept of emotional flow is then introduced along with a consideration of how it has been tacitly incorporated into the study of emotional health messages. Finally, the utility of the concept of emotional flow is elaborated by articulating the ways in which it might be harnessed to facilitate the creation of more effective health messages, individually as well as across campaigns. The article concludes with an agenda for future research.

    This article describes many of the issues in developing an efficient interface for communication on distributed memory machines. Although the hardware component of message latency is less than 1 ws on many distributed memory machines, the software latency associated with sending and receiving typed messages is on the order of 50 μs. The reason for this imbalance is that the software interface does not match the hardware. By changing the interface to match the hardware more closely, applications with fine grained communication can be put on these machines. This article describes several tests performed and many of the issues involvedmore » in supporting low latency messages on distributed memory machines.« less

    In an embodiment, a send thread receives an identifier that identifies a destination node and a pointer to data. The send thread creates a first send request in response to the receipt of the identifier and the data pointer. The send thread selects a selected channel from among a plurality of channels. The selected channel comprises a selected hand-off queue and an identification of a selected message unit. Each of the channels identifies a different message unit. The selected hand-off queue is randomly accessible. If the selected hand-off queue contains an available entry, the send thread adds the first send request to the selected hand-off queue. If the selected hand-off queue does not contain an available entry, the send thread removes a second send request from the selected hand-off queue and sends the second send request to the selected message unit.

    Fusion is based on high quality full length articles. However, in the words of the journal home page, `Nuclear Fusion welcomes Letters as a means to quickly communicate new, maybe preliminary, results which make a significant advancement of the knowledge in the field. Letters should be comprehensive and short, aiming for four printed pages including figures.' I would like to take the opportunity to reiterate this message and to say that, as Editor, I would welcome the submission of high quality Letters. Publishing procedures In-house, Nuclear Fusion's publishing procedures are subject to continuous scrutiny for potential improvements. Of particular note from 2008 are faster than ever peer review and publishing times that have been achieved despite the very rigorous processing to which submissions are subject. Readers may have noticed the implementation of the new article numbering system, announced by the Publisher, Yasmin McGlashan in 2008 Nucl. Fusion 48 010101. This new scheme gives us more flexibilty and has led to faster online publication. The Nuclear Fusion Office and IOP Publishing Just as the journal depends on the authors and referees, so its success is also due to the tireless and largely unsung efforts of the Nuclear Fusion Office in Vienna and IOP Publishing in Bristol. I would like to express my personal thanks to Maria, Katja, Sophy, Sarah, Rachael and Yasmin for the support that they have given to me, the authors and the referees. Season's Greetings I would like to wish our readers, authors, referees and Board of Editors a successful and happy 2009 and thank them for their contributions to Nuclear Fusion in 2008.

    Community opposition is a barrier to potable recycled water schemes. Effective communication strategies about such schemes are needed. Drawing on social psychological literature, two experimental studies are presented, which explore messages that improve public perceptions of potable recycled water. The Elaboration-Likelihood Model of information processing and attitude change is tested and supported. Study 1 (N = 415) premeasured support for recycled water, and trust in government information at Time 1. Messages varied in complexity and sidedness were presented at Time 2 (3 weeks later), and support and trust were remeasured. Support increased after receiving information, provided that participants received complex rather than simple information. Trust in government was also higher after receiving information. There was tentative evidence of this in response to two-sided messages rather than one-sided messages. Initial attitudes to recycled water moderated responses to information. Those initially neutral or ambivalent responded differently to simple and one-sided messages, compared to participants with positive or negative attitudes. Study 2 (N = 957) tested the effectiveness of information about the low relative risks, and/or benefits of potable recycled water, compared to control groups. Messages about the low risks resulted in higher support when the issue of recycled water was relevant. Messages about benefits resulted in higher perceived issue relevance, but did not translate into greater support. The results highlight the importance of understanding people's motivation to process information, and need to tailor communication to match attitudes and stage of recycled water schemes' development.

  7. What's in a message? Delivering sexual health promotion to young people in Australia via text messaging

    PubMed Central

    2010-01-01

    Background Advances in communication technologies have dramatically changed how individuals access information and communicate. Recent studies have found that mobile phone text messages (SMS) can be used successfully for short-term behaviour change. However there is no published information examining the acceptability, utility and efficacy of different characteristics of health promotion SMS. This paper presents the results of evaluation focus groups among participants who received twelve sexual health related SMS as part of a study examining the impact of text messaging for sexual health promotion to on young people in Victoria, Australia. Methods Eight gender-segregated focus groups were held with 21 males and 22 females in August 2008. Transcripts of audio recordings were analysed using thematic analysis. Data were coded under one or more themes. Results Text messages were viewed as an acceptable and 'personal' means of health promotion, with participants particularly valuing the informal language. There was a preference for messages that were positive, relevant and short and for messages to cover a variety of topics. Participants were more likely to remember and share messages that were funny, rhymed and/or tied into particular annual events. The message broadcasting, generally fortnightly on Friday afternoons, was viewed as appropriate. Participants said the messages provided new information, a reminder of existing information and reduced apprehension about testing for sexually transmitted infections. Conclusions Mobile phones, in particular SMS, offer health promoters an exciting opportunity to engage personally with a huge number of individuals for low cost. The key elements emerging from this evaluation, such as message style, language and broadcast schedule are directly relevant to future studies using SMS for health promotion, as well as for future health promotion interventions in other mediums that require short formats, such as social networking sites

  8. Alcohol Messages in Prime-Time Television Series

    RUSSELL, CRISTEL ANTONIA; RUSSELL, DALE W.

    2010-01-01

    Alcohol messages contained in television programming serve as sources of information about drinking. To better understand the ways embedded messages about alcohol are communicated, it is crucial to objectively monitor and analyze television alcohol depictions. This article presents a content analysis of an eight-week sample of eighteen prime-time programs. Alcohol messages were coded based on modalities of presentation, level of plot connection, and valence. The analysis reveals that mixed messages about alcohol often coexist but the ways in which they are presented differ: whereas negative messages are tied to the plot and communicated verbally, positive messages are associated with subtle visual portrayals.

  9. Extracting hidden messages in steganographic images

    2014-07-17

    The eventual goal of steganalytic forensic is to extract the hidden messages embedded in steganographic images. A promising technique that addresses this problem partially is steganographic payload location, an approach to reveal the message bits, but not their logical order. It works by finding modified pixels, or residuals, as an artifact of the embedding process. This technique is successful against simple least-significant bit steganography and group-parity steganography. The actual messages, however, remain hidden as no logical order can be inferred from the located payload. This paper establishes an important result addressing this shortcoming: we show that the expected mean residuals contain enough information to logically order the located payload provided that the size of the payload in each stego image is not fixed. The located payload can be ordered as prescribed by the mean residuals to obtain the hidden messages without knowledge of the embedding key, exposing the vulnerability of these embedding algorithms. We provide experimental results to support our analysis.

    A network of microprocessors, or nodes, are interconnected in an n-dimensional cube having bidirectional communication links along the edges of the n-dimensional cube. Each node's processor network includes an I/O subprocessor dedicated to controlling communication of message packets along a bidirectional communication link with each end thereof terminating at an I/O controlled transceiver. Transmit data lines are directly connected from a local FIFO through each node's communication link transceiver. Status and control signals from the neighboring nodes are delivered over supervisory lines to inform the local node that the neighbor node's FIFO is empty and the bidirectional link between the two nodes is idle for data communication. A clocking line between neighbors, clocks a message into an empty FIFO at a neighbor's node and vica versa. Either neighbor may acquire control over the bidirectional communication link at any time, and thus each node has circuitry for checking whether or not the communication link is busy or idle, and whether or not the receive FIFO is empty. Likewise, each node can empty its own FIFO and in turn deliver a status signal to a neighboring node indicating that the local FIFO is empty. The system includes features of automatic message rerouting, block message transfer and automatic parity checking and generation.

  8. Cri du Chat syndrome

    PubMed Central

    Cerruti Mainardi, Paola

    2006-01-01

    The Cri du Chat syndrome (CdCS) is a genetic disease resulting from a deletion of variable size occurring on the short arm of chromosome 5 (5p-). The incidence ranges from 1:15,000 to 1:50,000 live-born infants. The main clinical features are a high-pitched monochromatic cry, microcephaly, broad nasal bridge, epicanthal folds, micrognathia, abnormal dermatoglyphics, and severe psychomotor and mental retardation. Malformations, although not very frequent, may be present: cardiac, neurological and renal abnormalities, preauricular tags, syndactyly, hypospadias, and cryptorchidism. Molecular cytogenetic analysis has allowed a cytogenetic and phenotypic map of 5p to be defined, even if results from the studies reported up to now are not completely in agreement. Genotype-phenotype correlation studies showed a clinical and cytogenetic variability. The identification of phenotypic subsets associated with a specific size and type of deletion is of diagnostic and prognostic relevance. Specific growth and psychomotor development charts have been established. Two genes, Semaphorin F (SEMAF) and δ-catenin (CTNND2), which have been mapped to the "critical regions", are potentially involved in cerebral development and their deletion may be associated with mental retardation in CdCS patients. Deletion of the telomerase reverse transcriptase (hTERT) gene, localised to 5p15.33, could contribute to the phenotypic changes in CdCS. The critical regions were recently refined by using array comparative genomic hybridisation. The cat-like cry critical region was further narrowed using quantitative polymerase chain reaction (PCR) and three candidate genes were characterised in this region. The diagnosis is based on typical clinical manifestations. Karyotype analysis and, in doubtful cases, FISH analysis will confirm the diagnosis. There is no specific therapy for CdCS but early rehabilitative and educational interventions improve the prognosis and considerable progress has been made in

    A method for passing messages in a parallel computer system constructed as a plurality of compute nodes interconnected as a network where each compute node includes a DMA engine but includes only a limited number of byte counters for tracking a number of bytes that are sent or received by the DMA engine, where the byte counters may be used in shared counter or exclusive counter modes of operation. The method includes using rendezvous protocol, a source compute node deterministically sending a request to send (RTS) message with a single RTS descriptor using an exclusive injection counter to track both the RTS message and message data to be sent in association with the RTS message, to a destination compute node such that the RTS descriptor indicates to the destination compute node that the message data will be adaptively routed to the destination node. Using one DMA FIFO at the source compute node, the RTS descriptors are maintained for rendezvous messages destined for the destination compute node to ensure proper message data ordering thereat. Using a reception counter at a DMA engine, the destination compute node tracks reception of the RTS and associated message data and sends a clear to send (CTS) message to the source node in a rendezvous protocol form of a remote get to accept the RTS message and message data and processing the remote get (CTS) by the source compute node DMA engine to provide the message data to be sent.

  10. Middleware for Processing Message Queues with Elasticity Support and Sequential Integrity of Asynchronous Message Processing

    Elasticity in computing refers to dynamically adjusting the amount of allocated resources to process a distributed application. In order to achieve this, mechanisms are needed to avoid the phenomenon of the elasticity threshold detection moving constantly up or down. The existing work fails to deliver sequential integrity of asynchronous messages processing and the asymmetries of data distribution to achieve parallel consumption. This paper fills this gaps and proposes a middleware solution to dynamically analyze the flow of message queue, and a mechanism to increase the parallelized consumption based on the output behavior. An architecture for IOD (Increase On Demand) middleware is presented, with support for the increase and decrease of thread's to cope with the growth of message queues, using the technique of limit-based heuristics over a given period of time and grouping messages into sub-queues based on classification criteria.

    Instant messaging may compromise sleep quality and school performance in adolescents. We aimed to determine associations between nighttime messaging and daytime sleepiness, self-reported sleep parameters, and/or school performance. Students from 3 high schools in New Jersey completed anonymous questionnaires assessing sleep duration, daytime sleepiness, messaging habits, and academic performance. Of the 2,352 students sampled, 1,537 responses were contrasted among grades, sexes, and messaging duration, both before and after lights out. Students who reported longer duration of messaging after lights out were more likely to report a shorter sleep duration, higher rate of daytime sleepiness, and poorer academic performance. Messaging before lights out was not associated with higher rates of daytime sleepiness or poorer academic performance. Females reported more messaging, more daytime sleepiness, and better academic performance than males. There may be an association between text messaging and school performance in this cohort of students.

    2014-01-14

    Embodiments of the invention may be used to manage message queues in a parallel computing environment to prevent message queue deadlock. A direct memory access controller of a compute node may determine when a messaging queue is full. In response, the DMA may generate and interrupt. An interrupt handler may stop the DMA and swap all descriptors from the full messaging queue into a larger queue (or enlarge the original queue). The interrupt handler then restarts the DMA. Alternatively, the interrupt handler stops the DMA, allocates a memory block to hold queue data, and then moves descriptors from the full messaging queue into the allocated memory block. The interrupt handler then restarts the DMA. During a normal messaging advance cycle, a messaging manager attempts to inject the descriptors in the memory block into other messaging queues until the descriptors have all been processed.

    2015-01-01

    The NASA Goddard Mission Services Evolution Center (GMSEC) system is a message-based plug-and-play open system architecture used in many of NASA mission operations centers. This presentation will focus on the use of GMSEC standard messages to report and analyze the status of a system and enable the automation of the system's components. In GMSEC systems, each component reports its status using a keep-alive message and also publishes status and activities as log messages. In addition, the components can accept functional directive messages from the GMSEC message bus. Over the past several years, development teams have found ways to utilize these messages to create innovative display pages and increasingly sophisticated approaches to automation. This presentation will show the flexibility and value of the message-based approach to system awareness and automation.

    The Message Reporting System (MRS) in the ATLAS data acquisition system (DAQ) is one package of the Online Software which acts as a glue of various elements of DAQ, High Level Trigger (HLT) and Detector Control System (DCS). The aim of the MRS is to provide a facility which allows all software components in ATLAS to report messages to other components of the distributed DAQ system. The processes requiring a MRS are on one hand applications that report error conditions or information and on the other hand message processors that receive reported messages. A message reporting application can inject one or more messages into the MRS at any time. An application wishing to receive messages can subscribe to a message group according to defined criteria. The application receives messages that fulfill the subscription criteria when they are reported to MRS. The receiver message processing can consist of anything from simply logging the messages in a file/terminal to performing message analysis. The inter-process communication is achieved using the CORBA technology. The design, architecture and the used technology of MRS are reviewed in this paper.

    2010-12-01

    Focusing on several message features that are prominent in antismoking campaign literature, this content-analytic study examines 934 antismoking video clips on YouTube for the following characteristics: message sensation value (MSV) and three types of message appeal (threat, social and humor). These four characteristics are then linked to YouTube's interactive audience response mechanisms (number of viewers, viewer ratings and number of comments) to capture message reach, viewer preference and viewer engagement. The findings suggest the following: (i) antismoking messages are prevalent on YouTube, (ii) MSV levels of online antismoking videos are relatively low compared with MSV levels of televised antismoking messages, (iii) threat appeals are the videos' predominant message strategy and (iv) message characteristics are related to viewer reach and viewer preference.

    In an embodiment, a reception thread receives a source node identifier, a type, and a data pointer from an application and, in response, creates a receive request. If the source node identifier specifies a source node, the reception thread adds the receive request to a fast-post queue. If a message received from a network does not match a receive request on a posted queue, a polling thread adds a receive request that represents the message to an unexpected queue. If the fast-post queue contains the receive request, the polling thread removes the receive request from the fast-post queue. If the receive request that was removed from the fast-post queue does not match the receive request on the unexpected queue, the polling thread adds the receive request that was removed from the fast-post queue to the posted queue. The reception thread and the polling thread execute asynchronously from each other.

    Individuals seeking treatment for addiction often experience barriers due to cost, lack of local treatment resources, or either school or work schedule conflicts. Text messaging-based addiction treatment is inexpensive and has the potential to be widely accessible in real time. We conducted a comprehensive literature review identifying 11 published randomized controlled trials (RCTs) evaluating text messaging-based interventions for tobacco smoking, 4 studies for reducing alcohol consumption, 1 pilot study in former methamphetamine (MA) users, and 1 study based on qualitative interviews with cannabis users. Abstinence outcome results in RCTs of smokers willing to make a quit attempt have been positive overall in the short term and as far out as at 6 and 12 months. Studies aimed at reducing alcohol consumption have been promising. More data are needed to evaluate the feasibility, acceptability, and efficacy of this approach for other substance use problems.

    Cellular telephony has become a bright example of co-evolution of human society and information technology. This trend has also been reflected in health care and health promotion projects which included cell phones in data collection and communication chain. While many successful projects have been realized, the review of phone-based data collection techniques reveals that the existing technologies do not completely address health promotion research needs. The paper presents approaches which close this gap by extending existing versatile platforms. The messaging systems are designed for a health-promotion research to prevent obesity and obesity-related health disparities among low-income Latino adolescent girls. Messaging and polling mechanisms are used to communicate and automatically process response data for the target constituency. Preliminary survey data provide an insight on phone availability and technology perception for the study group.

  11. The perfect message at the perfect moment.

    2005-11-01

    Marketers planning promotional campaigns ask questions to boost the odds that the messages will be accepted: Who should receive each message? What should be its content? How should we deliver it? The one question they rarely ask is, when should we deliver it? That's too bad, because in marketing, timing is arguably the most important variable of all. Indeed, there are moments in a customer's relationship with a business when she wants to communicate with that business because something has changed. If the company contacts her with the right message in the right format at the right time, there's a good chance of a warm reception. The question of "when" can be answered by a new computer-based model called "dialogue marketing," which is, to date, the highest rung on an evolutionary ladder that ascends from database marketing to relationship marketing to one-to-one marketing. Its principle advantages over older approaches are that it is completely interactive, exploits many communication channels, and is "relationship aware": that is, it continuously tracks every nuance of the customer's interaction with the business. Thus, dialogue marketing responds to each transition in that relationship at the moment the customer requires attention. Turning a traditional marketing strategy into a dialogue-marketing program is a straightforward matter. Begin by identifying the batch communications you make with customers, then ask yourself what events could trigger those communications to make them more timely. Add a question or call to action to each message and prepare a different treatment or response for each possible answer. Finally, create a series of increasingly urgent calls to action that kick in if the question or call to action goes unanswered by the customer. As dialogue marketing proliferates, it may provide the solid new footing that Madison Avenue seeks.

  14. Low latency messages on distributed memory multiprocessors

    Rosing, Matthew; Saltz, Joel

    1993-01-01

    Many of the issues in developing an efficient interface for communication on distributed memory machines are described and a portable interface is proposed. Although the hardware component of message latency is less than one microsecond on many distributed memory machines, the software latency associated with sending and receiving typed messages is on the order of 50 microseconds. The reason for this imbalance is that the software interface does not match the hardware. By changing the interface to match the hardware more closely, applications with fine grained communication can be put on these machines. Based on several tests that were run on the iPSC/860, an interface that will better match current distributed memory machines is proposed. The model used in the proposed interface consists of a computation processor and a communication processor on each node. Communication between these processors and other nodes in the system is done through a buffered network. Information that is transmitted is either data or procedures to be executed on the remote processor. The dual processor system is better suited for efficiently handling asynchronous communications compared to a single processor system. The ability to send data or procedure is very flexible for minimizing message latency, based on the type of communication being performed. The test performed and the proposed interface are described.

    We investigate the structure of the strange attractor of a chaotic loss-modulated solid-state laser utilizing return maps based on a combination of intensity maxima and interspike intervals, as opposed to those utilizing Poincar{acute e} sections defined by the intensity maxima of the laser ({dot I}=0,{umlt I}{lt}0) alone. We find both experimentally and numerically that a simple, intrinsic relationship exists between an intensity maximum and the pair of preceding and succeeding interspike intervals. In addition, we numerically investigate encoding messages on the output of a chaotic transmitter laser and its subsequent decoding by a similar receiver laser. By exploiting the relationship between the intensity maxima and the interspike intervals, we demonstrate that the method utilized to encode the message is vital to the system{close_quote}s ability to hide the signal from unwanted deciphering. In this work alternative methods are studied in order to encode messages by modulating the magnitude of pumping of the transmitter laser and also by driving its loss modulation with more than one frequency. {copyright} {ital 1997} {ital The American Physical Society}

    A project using the entertainment media was developed to promote responsible sexual behavior of young people in the Philippines. Music videos by Lea Salonga and the group Menudo were used to sell the message of responsible sexual behavior and to encourage counseling for discussing and solving their problems. There were 2 parts: a commercial phase to make the songs hits with a social message, and an institutional phase to develop counseling centers and a telephone counseling service. The project was planned to use cost sharing with private corporations, and over $1.4 million was obtained from corporate sponsorship. Surveys after the project began showed that 92% of the young people heard the song and 90% like it. Over 51% stated that it had an impact on them, 44% talked to their parents about it, and 25% asked for contraceptive information. Of those surveyed, 83% said they were aware of the telephone counseling service offered. There were over 8,000 calls answered by the counselors. The lessons learned from this project were that the use of professionals and top materials can help gain corporate support and access to the media. By planning to use cost sharing and cost recovery methods, a challenge is presented to the staff to use creative approaches. The use of the right celebrities can aid visibility, credibility and excitement to the project. This approach can be a useful method to promote a social message and get the interest of the private sector.

Le developpement et l'utilisation d'un modele geothermique 1D tenant compte de la thermodependance du comportement mecanique ont permis d'evaluer que les etendues de pergelisol chaud deviendraient instables a la suite d'un rechauffement de l'ordre de 5°C sur cent ans. En effet, la resistance mecanique du pergelisol diminuera alors rapidement jusqu'a 11,6 MPa, ce qui correspond a une perte relative de 98% de la resistance par rapport a un scenario sans rechauffement.

  18. Source Similarity and Social Media Health Messages: Extending Construal Level Theory to Message Sources.

    2015-09-01

    Social media users post messages about health goals and behaviors to online social networks. Compared with more traditional sources of health communication such as physicians or health journalists, peer sources are likely to be perceived as more socially close or similar, which influences how messages are processed. This experimental study uses construal level theory of psychological distance to predict how mediated health messages from peers influence health-related cognition and behavioral intention. Participants were exposed to source cues that identified peer sources as being either highly attitudinally and demographically similar to or different from participants. As predicted by construal level theory, participants who perceived sources of social media health messages as highly similar listed a greater proportion of beliefs about the feasibility of health behaviors and a greater proportion of negative beliefs, while participants who perceived sources as more dissimilar listed a greater proportion of positive beliefs about the health behaviors. Results of the study could be useful in determining how health messages from peers could encourage individuals to set realistic health goals. PMID:26348816

    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.

  1. Quantum messages with signatures forgeable in arbitrated quantum signature schemes

    Even though a method to perfectly sign quantum messages has not been known, the arbitrated quantum signature scheme has been considered as one of the good candidates. However, its forgery problem has been an obstacle to the scheme becoming a successful method. In this paper, we consider one situation, which is slightly different from the forgery problem, that we use to check whether at least one quantum message with signature can be forged in a given scheme, although all the messages cannot be forged. If there are only a finite number of forgeable quantum messages in the scheme, then the scheme can be secured against the forgery attack by not sending forgeable quantum messages, and so our situation does not directly imply that we check whether the scheme is secure against the attack. However, if users run a given scheme without any consideration of forgeable quantum messages, then a sender might transmit such forgeable messages to a receiver and in such a case an attacker can forge the messages if the attacker knows them. Thus it is important and necessary to look into forgeable quantum messages. We show here that there always exists such a forgeable quantum message-signature pair for every known scheme with quantum encryption and rotation, and numerically show that there are no forgeable quantum message-signature pairs that exist in an arbitrated quantum signature scheme.

    Emerging adults receive messages about physical appearance from a range of sources, but few studies have examined the content of these messages. Undergraduates (N=154) who identified as African American, Latino American, and European American answered 4 open-ended questions about messages they perceived about physical appearance from family, peers, school, and media. Raters coded responses for content and affect. The most common messages perceived were the importance/non-importance of appearance, positive comments about appearance, and the link between attractiveness and success. The perception of these messages frequently differed by gender and source, but rarely by ethnicity. Women perceived more frequent and more negative messages than did men. Individuals perceived the media as transmitting more negative messages and the family more healthful and positive ones. PMID:19410527

    Background There is no functional pharmacovigilance system in Cambodia to our knowledge. Mobile phone–based tools, such as short message service (SMS) text messages, are increasingly used for surveillance purposes. Objective To pilot-test the FrontlineSMS mobile phone–based tool for notification of adverse events, using Cambodia’s only International Vaccination Center at the Institut Pasteur du Cambodge as a field site. Methods People receiving vaccinations, aged over 18 years, and who owned a cell phone were recruited in the study following informed consent. The names and mobile phone numbers of the participants interviewed were entered each day into the FrontlineSMS software. Two days after being vaccinated, participants received an automatically generated SMS text message asking whether any adverse events had occurred. Their SMS reply was number-coded and exported from the software daily to an Excel spreadsheet and examined before being saved. If the participant replied with a code for a severe adverse event (8 or 9), they were automatically advised to consult the nearest doctor. Results The active surveillance study was conducted over 72 days in the spring of 2012. Patients agreed to be asked by SMS text message whether unwanted events had occurred after vaccination. Of 1331 persons aged over 18 years referred to the vaccination unit, 184 (13.8%) were asked and agreed to participate. When texted for clinical status 48 hours after vaccination, 52 (28.3%) participants did not reply, 101 (54.9%) sent an immediate SMS reply, and 31 (16.8%) sent an SMS reply after additional prompting. Of the initial 184 participants, 132 (71.7%) replied. These 132 participants received 135 vaccine doses and 109 (82.6%) reported no adverse events, whereas 23 (17.4%) reported adverse events, all benign. Conclusions Notification using an SMS-based text message system is already used in Cambodia for syndromic surveillance in health centers and reporting by health care workers

  5. Message generalizations that support evidence-based persuasive message design: specifying the evidentiary requirements.

    2015-01-01

    Evidence-based persuasive message design can be informed by dependable research-based generalizations about the relative persuasiveness of alternative message-design options. Five propositions are offered as specifying what constitutes the best evidence to underwrite such generalizations: (1) The evidence should take the form of replicated randomized trials in which message features are varied. (2) Results should be described in terms of effect sizes and confidence intervals, not statistical significance. (3) The results should be synthesized using random-effects meta-analytic procedures. (4) The analysis should treat attitudinal, intention, and behavioral assessments as yielding equivalent indices of relative persuasiveness. (5) The replications included in research syntheses should not be limited to published studies or to English-language studies.

    Message content in anti-smoking public service announcements (PSAs) can be delivered explicitly (directly with concrete statements) or implicitly (indirectly via metaphor), and the method of delivery may affect the efficacy of those PSAs. The purpose of this study was to conduct an initial test of this hypothesis, using tobacco industry manipulation PSAs in adolescents. A 2 (age: 11-14 years old; 15-17 years old) × 2 (message delivery: implicit, explicit) mixed model design was used. There was a significant main effect of message delivery: Tobacco industry manipulation PSAs that delivered their messages explicitly were associated with stronger levels of smoking resistance self-efficacy compared to tobacco industry manipulation PSAs that delivered their messages implicitly. No significant main effects of age were found nor were any interactions between age and message delivery. These results suggest that message delivery factors should be taken into account when designing anti-smoking PSAs. PMID:20071100

    Two experiments investigated the processes through which post-message behavior (e.g., noncompliance) influences resistance to the message. Participants in Experiment 1 read preventive, consumer-education messages that either opposed the consumption of an alcohol-like product or recommended moderation. Half of the participants then tried the product, whereas the remaining participants performed a filler task. In the absence of trial, the two messages had the same effect. However, recipients of the abstinence-promoting preventive message who tried the product had stronger intentions to use the product in the future than recipients of the moderation message. This finding suggests that assessments of message impact may be inadequate unless an opportunity for trial is also provided. Results are interpreted in terms of self-perception and cognitive dissonance and contrasted from psychological reactance. PMID:15018672

Qualité des données D’abondantes recherches ont été publiées sur la fiabilité intra-évaluateur, inter-évaluateur et test-retest ainsi que sur la validité convergente, prédictive, du contenu et des groupes connus du test HINT, de même que sur la sensibilité, la spécificité et les valeurs prédictives négatives et positives des inquiétudes des parents, telles qu’évaluées par le test HINT. La plupart des données probantes sont de niveau II. Message principal Il est important de diagnostiquer les retards du développement moteur durant la première année de vie, car ils sont souvent le signe de retards du développement généralisés ou de déficiences précises, telles que la paralysie cérébrale. Les inquiétudes des parents quant au développement moteur de leur enfant sont une valeur prédictive robuste de diagnostics subséquents de retard du développement moteur. Conclusion Seul le dépistage précoce des retards du développement moteur, initialement par l’entremise d’outils de dépistage comme le test HINT, permet de recommander le patient à une intervention précoce qui profiterait tant à l’enfant qu’à sa famille.

    This article was based on a speech presented at a Plenary Session of the 1996 Annual Meeting of the American Society of Tropical Medicine and Hygiene. The address describes the nature of social marketing with examples and some lessons learned in developing countries. The earliest social marketers were Moses with the Ten Commandments of God and Indian religious authorities with fertility motifs inscribed on temple walls. Modern marketers of beer and snack food preempted the ancients and made social marketing more ingenious. The strategy shifted to supplying a product to satisfy a consumer want. Messages became a two-way process that minimized feedback shock. Focus groups were used to probe consumers' thoughts. Research must probe the total environment of the "problem." In Brazil, breast feeding promotions revealed that the perceived problem may not be the real problem, and there was no single magic solution. Most tropical disease prevention approaches do not rely on multistage strategies. The oral rehydration therapy (ORT) strategy became a world-wide model when strategists realized that the formula had to be easy to remember, diarrhea had to be recognized as a disease, and the function of ORT had to be clearly defined. The Bangladesh Social Marketing Campaign was successful in getting men to discuss family planning with their wives and establishing the family planning worker as a heroine. Effective messages must uncover points of resistance to the message. Public health advances in the 19th century were due to social policy to improve water supply, sanitation, and nutrition. The iodization of salt in Ecuador was possible with political will, public awareness, redirection of perception, and motivation of demand. Social marketing resources exist in all countries nowadays. Only medical and scientific professionals can promote concern about tropical diseases and raise the prevention priority on the public agenda. PMID:9311633

    A historical approach is used in presenting the life cycle development of the Navy's message processing and distribution system beginning with the planning phase and ending with the integrated logistic support phase. Several maintenance problems which occurred after the system was accepted for fleet use were examined to determine if they resulted from errors in the acquisition process. The critical decision points of the acquisition process are examined and constructive recommendations are made for avoiding the problems which hindered the successful development of this system.

    The inference of gene-regulatory processes from gene-expression data belongs to the major challenges of computational systems biology. Here we address the problem from a statistical-physics perspective and develop a message-passing algorithm which is able to infer sparse, directed and combinatorial regulatory mechanisms. Using the replica technique, the algorithmic performance can be characterized analytically for artificially generated data. The algorithm is applied to genome-wide expression data of baker's yeast under various environmental conditions. We find clear cases of combinatorial control, and enrichment in common functional annotations of regulated genes and their regulators.

  15. Source entitativity and the elaboration of persuasive messages: the roles of perceived efficacy and message discrepancy.

    PubMed

    Clark, Jason K; Wegener, Duane T

    2009-07-01

    Compared with nonentitative groups, entitative targets are considered to elicit more elaborative processing because of the singularity or unity they represent. However, when groups serve as sources of persuasive messages, other dynamics may operate. The current research suggests that entitativity is intrinsically linked to perceptions of a group's efficacy related to the advocacy, and this efficacy combines with the position of the appeal to determine message elaboration. When messages are counterattitudinal, entitative (efficacious) sources should elicit greater processing than nonentitative groups because of concern that the entitative sources may be more likely to bring about the negative outcomes proposed. However, when appeals are proattitudinal, sources low in entitativity (nonefficacious) should initiate more elaboration due to concern that they may be unlikely to facilitate the positive outcomes proposed. These hypotheses were supported in a series of studies. Preliminary studies established the entitativity-efficacy relation (Studies 1A and 1B). Primary persuasion studies showed that manipulations of source entitativity (Studies 2 and 3) and source efficacy (Studies 4A and 4B) have opposite effects on processing as a function of message discrepancy.

  17. Independent communication messages: methodology and applications

    SciTech Connect

    Cooper, J.A.

    Information flowing on communication buses is ordinarily ``non-random`` in the sense that data entities are not equally likely and independent. This is because they have relationships to each other and to physical occurrences to which they may be responding. Random data would convey no information or meaning. From a different viewpoint, there can be applications for creating randomness characteristics, and four of these are described in this paper. Two examples derive from cryptology and the other two from safety. One cryptology application described is the generation of random numbers for use as, for example, keys, hash functions, nonces, and seeds. The other is for inter-message ``padding`` to resist traffic analysis by masking when data are being transmitted and when the channel is conveying no information. One of the safety applications described is the ``unique signal`` approach used in modern nuclear weapon electrical safety. The other is the use of unique signals as non-weapon critical-operation control functions. Both of these safety applications require provisions to help assure randomness characteristics in any inadvertently occurring inputs. In order to satisfy these cryptology and safety needs, communication strategies are described that generate or selectively encourage independent (unrelated) symbols or messages.

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

    Filipino illustrated magazines, or the comics, may yet prove to be the most effective media, if not the most effective, for spreading the country's development messages. Long criticized by intellectuals and the social elite, the comics have been grossly underrated in their potential to inform, persuade, and even influence the life-style of the people. The government's Commission on Population (Popcom) has developed an information-education-communication program using the comics, among other media, to disseminate stories on family planning, responsible parenthood, and related topics. Its best quality is popular appeal, and for publishers and distribution outlets, the comics provide good business. A review of these materials shows that their themes reflect the following topics or issues: 1) population trends and consequences; 2) socioeconomic benefits of family planning; 3) customs which influence family planning; 4) family planning concepts; 5) family planning methods; 6) human sexuality and reproduction; 7) the husband-wife relationship; 8) guides for family planning motivation or communication; and 9) guides for teaching family planning. The materials were developed with 4 qualities in mind so as to attract audience or reader interest: simplicity, familiarity, realism, and attractiveness of materials. The consensus is that in the comics, population and development agencies may have found a "secret weapon" in getting these messages across, and that this new-found use for the illustrated magazines may be giving them a new respectability without in any way diminishing their popular appeal.

    Evidence linking both active smoking and secondhand smoke exposure to premenopausal breast cancer makes the development of health messages specific to younger women a pressing priority. To determine how to communicate information about this modifiable breast cancer risk to young women, we analyzed a selection of 32 recent English-language breast cancer messages and campaigns that targeted young women. In addition, we obtained young women's responses to three breast cancer campaign images during focus group discussions. A visual analysis of messages points to an explicitly gendered discourse within contemporary campaigns, one that entails conflicting messages regarding breast cancer, health, feminine beauty, and risk. Although the intent might be to educate and empower young women to "fight" against breast cancer, paradoxically, the messages employ imagery that sexually objectifies young women's breasts and bodies. Recommendations are made for messaging about tobacco and breast cancer risk to avoid reproducing one-dimensional or stereotypical presentations of gender and femininity.

    2015-01-01

    Health message quality is best understood in terms of a message’s ability to effectively produce change in the variables that it was designed to change. The importance of determining a message’s effectiveness in producing change prior to implementation is clear: The better a message’s potential effectiveness is understood, the better able interventionists are to distinguish effective from ineffective messages before allocating scarce resources to message implementation. For this purpose, research has relied on perceived message effectiveness measures as a proxy of a message’s potential effectiveness. Remarkably, however, very little conceptual work has been done on perceived message effectiveness, which renders its measures under-informed and inconsistent across studies. To encourage greater conceptual work on this important construct, we review several threats to the validity of existing measures and consider strategies for improving our understanding of perceived message effectiveness.

    The most widely played song in Mexico in March 1986 is a special record designed to encourage young people to be sexually responsible and not to bring into the world children they cannot care for. "It's OK to say 'no,'" is the message of a unique new family planning and health communication project designed to reach young people in 11 Spanish speaking countries of Latin America and the Caribbean. What makes this ambitious regional project so unique is not just the message or the remarkable success of the 1st song but the combination of materials that were produced, the way they were produced, and how they are now being used throughout the region. The Population Communication Services project in the Johns Hopkins School of Hygiene and Public Health (JHU/PCS) has been working in Latin America and elsewhere for 4 years to support innovative family planning communication projects. It became evident that 1 key group was not being reached, i.e., young people aged 13-18 who comprise approximately 30% of the total population in Latin America. The fertility and sexual behavior of young people have a significant impact on their own lives, their community, their country, and the region. Early pregnancy is a major health and social problem throughout the region and the world. To address this problem, the JHU/PCS decided to develop a regional Latin American project to make young people more sharply aware of the personal advantages to them of responsible parenthood. JHU/PCS put together a financial, marketing, and institutional package. The US Agency for International Development (USAID) provided the finances. Analysis showed that the common denominator for young people throughout the region is music.

    Event Driven Messaging with Role-Based Subscriptions (EDM-RBS) is a framework integrated into the Service Management Database (SMDB) to allow for role-based and subscription-based delivery of synchronous and asynchronous messages over JMS (Java Messaging Service), SMTP (Simple Mail Transfer Protocol), or SMS (Short Messaging Service). This allows for 24/7 operation with users in all parts of the world. The software classifies messages by triggering data type, application source, owner of data triggering event (mission), classification, sub-classification and various other secondary classifying tags. Messages are routed to applications or users based on subscription rules using a combination of the above message attributes. This program provides a framework for identifying connected users and their applications for targeted delivery of messages over JMS to the client applications the user is logged into. EDMRBS provides the ability to send notifications over e-mail or pager rather than having to rely on a live human to do it. It is implemented as an Oracle application that uses Oracle relational database management system intrinsic functions. It is configurable to use Oracle AQ JMS API or an external JMS provider for messaging. It fully integrates into the event-logging framework of SMDB (Subnet Management Database).

Results of two studies show that regulatory fit: a) increases the impact of a political message favoring nuclear energy on implicit attitudes of the target audience (Study 1); and b) induces a more positive evaluation of, and intentions to vote for, the political candidate who is delivering a message concerning immigration policies (Study 2).

    Background Hispanic adults in the United States are at particular risk for diabetes and inadequate blood pressure control. Physical activity improves these health problems; however Hispanic adults also have a low rate of recommended aerobic physical activity. To address improving physical inactivity, one area of rapidly growing technology that can be utilized is text messaging (short message service, SMS). A physical activity research team, Text4Walking, had previously developed an initial database of motivational physical activity text messages in English that could be used for physical activity text messaging interventions. However, the team needed to translate these existing English physical activity text messages into Spanish in order to have culturally meaningful and useful text messages for those adults within the Hispanic population who would prefer to receive text messages in Spanish. Objective The aim of this study was to translate a database of English motivational physical activity messages into Spanish and review these text messages with a group of Spanish speaking adults to inform the use of these text messages in an intervention study. Methods The consent form and study documents, including the existing English physical activity text messages, were translated from English into Spanish, and received translation certification as well as Institutional Review Board approval. The translated text messages were placed into PowerPoint, accompanied by a set of culturally appropriate photos depicting barriers to walking, as well as walking scenarios. At the focus group, eligibility criteria for this study included being an adult between 30 to 65 years old who spoke Spanish as their primary language. After a general group introduction, participants were placed into smaller groups of two or three. Each small group was asked to review a segment of the translated text messages for accuracy and meaningfulness. After the break out, the group was brought back together

  9. Protocols for Handling Messages Between Simulation Computers

    NASA Technical Reports Server (NTRS)

    Balcerowski, John P.; Dunnam, Milton

    2006-01-01

    Practical Simulator Network (PSimNet) is a set of data-communication protocols designed especially for use in handling messages between computers that are engaging cooperatively in real-time or nearly-real-time training simulations. In a typical application, computers that provide individualized training at widely dispersed locations would communicate, by use of PSimNet, with a central host computer that would provide a common computational- simulation environment and common data. Originally intended for use in supporting interfaces between training computers and computers that simulate the responses of spacecraft scientific payloads, PSimNet could be especially well suited for a variety of other applications -- for example, group automobile-driver training in a classroom. Another potential application might lie in networking of automobile-diagnostic computers at repair facilities to a central computer that would compile the expertise of numerous technicians and engineers and act as an expert consulting technician.

  10. Key Messages in prescribing for stoma care.

    PubMed

    Fake, Jeanette; Skipper, Gill

    With £248 million spent on stoma appliances and accessories throughout England in 2013 (Health and Social Care Information Centre, 2014) value for money and control of this process is seen to be of high priority. This does not have to mean restricted access of appliances, rather that there is appropriate usage of the budget. This article looks at how the stoma care team collaborated with the local clinical commissioning group (CCG) in order for the local surgeries to gain a better understanding of the needs of their local stoma care population. It was hoped that this would facilitate further control in the ordering (by the patient or GP) of stoma care products. The Key Messages produced are to be used as a tool to aid cost-effective stoma care.

  11. Making clear messages. What works best?

    PubMed

    1998-01-01

    The March-May 1998 issue of "AIDS Action" provides suggestions on how to develop educational materials for HIV/AIDS prevention campaigns. The key is to match materials to the overall plan. This entails careful consideration of campaign goals, the target population, and desired outcomes (e.g., improvements in knowledge, development of problem-solving or practical skills, attitudinal or behavioral change). The materials should use culturally appropriate language and illustrations, attractive colors and designs, and a nonjudgmental tone. Messages based on fear (e.g., "AIDS kills") should be avoided, as should images that promote discrimination against people with AIDS or groups such as sex workers. The best materials present information in a clear, respectful way and empower people to make their own decisions.

    Using Gray and McNaughton's (2000) revised reinforcement sensitivity theory (r-RST), we examined the influence of personality on processing of words presented in gain-framed and loss-framed anti-speeding messages and how the processing biases associated with personality influenced message acceptance. The r-RST predicts that the nervous system regulates personality and that behaviour is dependent upon the activation of the behavioural activation system (BAS), activated by reward cues and the fight-flight-freeze system (FFFS), activated by punishment cues. According to r-RST, individuals differ in the sensitivities of their BAS and FFFS (i.e., weak to strong), which in turn leads to stable patterns of behaviour in the presence of rewards and punishments, respectively. It was hypothesised that individual differences in personality (i.e., strength of the BAS and the FFFS) would influence the degree of both message processing (as measured by reaction time to previously viewed message words) and message acceptance (measured three ways by perceived message effectiveness, behavioural intentions, and attitudes). Specifically, it was anticipated that, individuals with a stronger BAS would process the words presented in the gain-frame messages faster than those with a weaker BAS and individuals with a stronger FFFS would process the words presented in the loss-frame messages faster than those with a weaker FFFS. Further, it was expected that greater processing (faster reaction times) would be associated with greater acceptance for that message. Driver licence holding students (N=108) were recruited to view one of four anti-speeding messages (i.e., social gain-frame, social loss-frame, physical gain-frame, and physical loss-frame). A computerised lexical decision task assessed participants' subsequent reaction times to message words, as an indicator of the extent of processing of the previously viewed message.

    To diagnose hypertension, multiple blood pressure (BP) measurements are recommended. We randomized patients into three groups: EMR-only (patients recorded BP measurements in an electronic medical record [EMR] web portal), EMR + reminders (patients were sent text message reminders to record their BP measurements in the EMR), and bi-directional text messaging (patients were sent a text message asking them to respond with their current BP). Subjects were asked to complete 14 measurements. Automated messages were sent to each patient in the bi-directional text messaging and EMR + reminder groups twice daily. Among 121 patients, those in the bi-directional text messaging group reported the full 14 measurements more often than both the EMR-only group (P < .001) and the EMR + reminders group (P = .038). Also, the EMR + reminders group outperformed the EMR-only group (P < .001). Bi-directional automated text messaging is an effective way to gather patient BP data. Text-message-based reminders alone are an effective way to encourage patients to record BP measurements.

    2015-01-01

    In recent years, the United States has recognized an increasing need for individual-level disaster preparedness, with federal, state, and local government agencies finding only limited success in instituting campaign-based disaster preparedness programs. Extant research indicates Americans generally remain poorly informed and badly unprepared for imminent disasters. Vested interest theory (Crano, 1997) is presented as a framework for designing and testing the effectiveness of television-based disaster preparedness campaign messages. High- and low-vested versions of an extant control message are compared to assess message efficacy as indicated by behavioral intentions, message acceptance, and preparedness related attitudes. Results indicate television-based video public service announcements manipulated with subtle message variations can be effective at influencing critical preparedness-related attitudes. The high-vested condition performed significantly better than the low-vested and control conditions for both behavioral intentions and perceptions of self-efficacy, two vitally important outcome variables associated with disaster preparedness.

    2013-07-01

    Social interaction promotes the spread of values, attitudes, and behaviors. Here, we report on neural responses to ideas that are destined to spread. We scanned message communicators using functional MRI during their initial exposure to the to-be-communicated ideas. These message communicators then had the opportunity to spread the messages and their corresponding subjective evaluations to message recipients outside the scanner. Successful ideas were associated with neural responses in the communicators' mentalizing systems and reward systems when they first heard the messages, prior to spreading them. Similarly, individuals more able to spread their own views to others produced greater mentalizing-system activity during initial encoding. Unlike prior social-influence studies that focused on the individuals being influenced, this investigation focused on the brains of influencers. Successful social influence is reliably associated with an influencer-to-be's state of mind when first encoding ideas. PMID:23722983

    In the United States, Blacks are disproportionately impacted by HIV/AIDS. Sexual networks and concurrent relationships have emerged as important contributors to the heterosexual transmission of HIV. To date, Africa is the only continent where an understanding of the impact of sexual concurrency has been conveyed in HIV prevention messaging. This project was developed by researchers and members of the Seattle, WA African American and African-Born communities, using the principles of community-based participatory research (CBPR). Interest in developing concurrency messaging came from the community and resulted in the successful submission of a community-academic partnership proposal to develop and disseminate HIV prevention messaging around concurrency. We describe: (a) the development of concurrency messaging through the integration of collected formative data and findings from the scientific literature; (b) the process of disseminating the message in the local Black community; and (c) important factors to consider in the development of similar campaigns.

    This pilot study tested the influence of nutrition message framing on snack choice among kindergarteners. Three classrooms were randomly assigned to watch one of the following 60s videos: (a) a gain-framed nutrition message (i.e. the positive benefits of eating apples) (n=14); (b) a loss-framed message (i.e. the negative consequences of not eating apples) (n=18); or (c) a control scene (children playing a game) (n=18). Following this, the children were offered a choice between animal crackers and an apple for their snack. Among the children who saw one of the nutrition message videos, 56% chose apples rather than animal crackers; in the control condition only 33% chose apples. This difference was statistically significant (chi2=7.56, p<0.01). These results suggest that videos containing nutritional messages may have a positive influence on children's short-term food choices.

    Objective. This paper aims to assess the effectiveness of reinforcement of oral health education message through short messaging service (SMS) in mobile phones. Material and Methods. 400 subjects from two colleges (200 from each college) belonging to 18–20 years age group possessing mobile phones were randomly selected and baseline examination of oral hygiene and gingival status was carried out using Oral Hygiene Index (OHI) and Gingival Index (GI). Oral health education was provided to all the subjects. Oral health education message was reinforced through short messaging service (SMS) in mobile phones for the subjects belonging to the intervention group. There was no such reinforcement for the control group. Follow-up examinations were done at the end of 1st, 2nd, 3rd, and 6th month. After the 3rd month, subjects of the intervention group did not receive oral health education message through short messaging service (SMS) and were followed up after next three months. Compiled data was analyzed using SPSS version 16 statistical software. Result. Mean OHI and GI scores in intervention group were significantly (p < 0.01) less than those of control group after the 2nd, 3rd, and 6th month. Conclusion. Reinforcement of oral health education message through short messaging service (SMS) is effective media to improve oral health. PMID:26941793

    Rural, low-income mothers face challenges to their health equal to or greater than those of low-income mothers from urban areas. This study put health message design into the hands of low-income rural mothers. The current study filled a research gap by analyzing a participatory process used to design health messages tailored to the everyday lives of rural low-income mothers. A total of forty-three mothers participated in nine focus groups, which were held from 2012 to 2013, in eight states. The mothers were from different racial and ethnic backgrounds. Participants discussed food security, physical activity, and oral health information. They created messages by considering several elements: visuals, length of message, voice/perspective, self-efficacy and personal control, emotional appeals, positive and negative reinforcements, and steps to health behavior change. This study was innovative in its focus on empowerment as a key process to health message design.

    Les plaies du tendon patellaire sont peu fréquentes et sont peu rapportés dans la littérature, contrairement aux ruptures sous cutanées. Les sections du tendon patellaire nécessitent une réparation immédiate afin de rétablir l'appareil extenseur et de permettre une récupération fonctionnelle précoce. A travers ce travail rétrospectif sur 13 cas, nous analysons les aspects épidémiologiques, thérapeutiques et pronostiques de ce type de pathologie en comparant différents scores. L’âge moyen est de 25 ans avec une prédominance masculine. Les étiologies sont dominées par les accidents de la voie publique (68%) et les agressions par agent tranchant (26%) et contendant (6 %). Tous nos patients ont bénéficié d'un parage chirurgical avec suture tendineuse direct protégée par un laçage au fils d'aciers en légère flexion. La rééducation est débutée après sédation des phénomènes inflammatoires. Au dernier recul les résultats sont excellents et bon à 92%. Nous n'avons pas noté de différence de force musculaire et d'amplitude articulaire entre le genou sain et le genou lésé. Les lésions ouvertes du tendon patellaire est relativement rare. La prise en charge chirurgicale rapide donne des résultats assez satisfaisants. La réparation est généralement renforcée par un semi-tendineux, synthétique ou métallique en forme de cadre de renfort pour faciliter la réadaptation et réduire le risque de récidive après la fin de l'immobilisation.

    Martin, Robin; Hewstone, Miles; Martin, Pearl Y

    2007-01-01

    Two experiments investigated the conditions under which majority and minority sources instigate systematic processing of their messages. Both experiments crossed source status (majority vs. minority) with message quality (strong vs. weak arguments). In each experiment, message elaboration was manipulated by varying either motivational (outcome relevance, Experiment 1) or cognitive (orientating tasks, Experiment 2) factors. The results showed that when either motivational or cognitive factors encouraged low message elaboration, there was heuristic acceptance of the majority position without detailed message processing. When the level of message elaboration was intermediate, there was message processing only for the minority source. Finally, when message elaboration was high, there was message processing for both source conditions. These results show that majority and minority influence is sensitive to motivational and cognitive factors that constrain or enhance message elaboration and that both sources can lead to systematic processing under specific circumstances.

    Methods to extract information from the tracking of mobile objects/particles have broad interest in biological and physical sciences. Techniques based on the simple criterion of proximity in time-consecutive snapshots are useful to identify the trajectories of the particles. However, they become problematic as the motility and/or the density of the particles increases because of the uncertainties on the trajectories that particles have followed during the acquisition time of the images. Here, we report efficient methods for learning parameters of the dynamics of the particles from their positions in time-consecutive images. Our algorithm belongs to the class of message-passing algorithms, also known in computer science, information theory and statistical physics under the name of Belief Propagation (BP). The algorithm is distributed, thus allowing parallel implementation suitable for computations on multiple machines without significant inter-machine overhead. We test our method on the model example of particle tracking in turbulent flows, which is particularly challenging due to the strong transport that those flows produce. Our numerical experiments show that the BP algorithm compares in quality with exact Markov Chain Monte-Carlo algorithms, yet BP is far superior in speed. We also suggest and analyze a random-distance model that provides theoretical justification for BP accuracy. Methods developed here systematically formulate the problem of particle tracking and provide fast and reliable tools for its extensive range of applications.

    Trinidad and Tobago are using educational programs to help the prevention of the spread of acquired immunodeficiency syndrome (AIDS). They have used posters and dramatic presentations on television, and have timed presentations to key periods like carnival activities. Also, popular singing groups have been used to send the message to young people. Both government and private groups are focusing their efforts on care for people with AIDS. The Red Cross, in concert with family planning organizations and religious groups, are working together to educate and help care for people with AIDS. AIDS patients not only have to contend with the disease, but the discrimination that also wears them down, and even rejection by their own families. The family planning group will target women, with little education, and the Red Cross will target teachers and school children. Educational materials have been developed, including a workbook using the question and answer format, a cartoon booklet, and a brochure, all written in simple language. These major organizations are setting the pace and many other local groups are getting involved, including community and volunteer groups. They will help with the homeless and those with drug problems in fund raising and volunteer activities for an AIDS hotline. PMID:12282759

    In a Literacy, Population, and Family Planning Education workshop held in New Delhi in 1970, Asian development and communication planners acknowledged the potential of puppetry as a method of education and social development. In 1975, the National Media Center (NMPC) created its Nutrition Communication Office (NCO) to disperse information for the Philippine Nutrition Programme. The medium of puppetry was employed because of its low cost and popularity. The NCO understood its goals of promoting good nutritional habits and beliefs among children and met these goals by testing the feasibility of puppet theater, running training workshops for interested individuals and groups, and by continuing to evaluate and review programs and reactions. In the past 11 years, the National Media Production Center has grown to develop programs on population, agriculture, values, the role of rural women and good health habits. Evaluation and review of the success of puppet theater programs has shown that a very high percentage of children understand the messages of the shows and approve of this method of instruction and entertainment.

    2010-04-01

    The world is experiencing a rapid rise in chronic health problems, which places an enormous burden on health care services. Modifiable health behaviors are largely responsible for this high prevalence and incidence of chronic diseases. This realization has made initiatives that promote healthy behaviors an international and interdisciplinary priority. How can nurses and other health care providers get the message across to their patients in order to maximize likelihood of leading to desired outcomes? Message tailoring is a well-established health communication approach shown to increase the persuasiveness of message effects in the promotion of healthy behaviors. Message framing is an effective message tailoring strategy that has been well-studied in the psychology literature over the past 20-plus years across a breadth of health behaviors while being severely understudied in the nursing literature. Numerous variables, especially those related to individual differences, have been shown to moderate message framing effects, a finding of great utility for nursing. This article presents a detailed review of the current state of the message framing literature, offers specific suggestions for advancing this literature, and highlights implications for research, education, and practice, with particular attention to nurses.

    Large-scale information processing environments must rapidly search through massive streams of raw data to locate useful information. These data streams contain textual and numeric data items, and may be highly structured or mostly freeform text. This project aims to create a high performance and scalable engine for locating relevant content in data streams. Based on the J2EE Java Messaging Service (JMS), the content-based messaging (CBM) engine provides highly efficient message formatting and filtering. This paper describes the design of the CBM engine, and presents empirical results that compare the performance with a standard JMS to demonstrate the performance improvements that are achieved.

    This exploratory study applies Taylor's (1999) six-segment message strategy wheel to direct-to-consumer (DTC) pharmaceutical television commercials to understand message strategies adopted by pharmaceutical advertisers to persuade consumers. A convenience sample of 96 DTC commercial campaigns was analyzed. The results suggest that most DTC drug ads used a combination approach, providing consumers with medical and drug information while simultaneously appealing to the viewer's ego-related needs and desires. In contrast to ration and ego strategies, other approaches including routine, acute need, and social are relatively uncommon while sensory was the least common message strategy. Findings thus recognized the educational value of DTC commercials.

    2004-01-01

    We conducted a trial of mobile phone text messaging (short message service; SMS) for diabetes management. In an eight-month period, 23 diabetic patients used the service. Patients used SMS to transmit data such as blood glucose levels and body weight to a server. The server automatically answered with an SMS acknowledgement message. A monthly calculated glycosylated haemoglobin result was also automatically sent to the patient by SMS. During the trial the patients sent an average of 33 messages per month. Although users showed good acceptance of the SMS diabetes system, they expressed various concerns, such as the inability to enter data from previous days. Nonetheless, the trial results suggest that SMS may provide a simple, fast and efficient adjunct to the management of diabetes. It was particularly useful for elderly persons and teenagers, age groups that are known to have difficulty in controlling their diabetes.

    Data transfer and messaging is an important part of a spacecraft. Creating a standard protocol for messaging that can be used for a variety of applications is an extremely beneficial project at the Jet Propulsion Laboratory (JPL). The Asynchronous Messaging Service (AMS) is a protocol outlining how subsystems initialize and conduct communication between each other. There are currently two implementations of AMS in the works. At JPL, my task is to get a working implementation of AMS onto vxWorks as a proof of concept. An Autocoder, a program used to convert visually created state chart diagrams to C++, has also been created to accomplish a part of the implementation. I was assigned to make the program portable on any Unix type environment. Lastly, I was to develop a program to demonstrate messaging between two FireWire cards running vxworks.

    A methodology to construct specific messages with clear objectives inside clinical processes, while simultaneously including contextual information, remains a problem today. This paper addresses the issue of combining specific message context (process driven) with the context of a patient record (patient centered). In Belgium, simplified conceptual models for Electronic Patient Record (EPR) architecture and for message architecture, based on previous comprehensive and international work, have been produced, validated and mapped into an integrated message format. The resulting model described in this paper highlights the main conceptual links between both basic models: at the action level and at the Transaction level. Using XML, some parts of the model have already been implemented in various national projects. Key lessons learned may be imported at the international level. PMID:15360968

    A major question posed by the design of an integrated voice information display/warning system for next-generation helicopter cockpits is whether an alerting prefix should precede voice warning messages; if so, the characteristics desirable in such a cue must also be addressed. Attention is presently given to the results of a study which ascertained pilot response time and response accuracy to messages preceded by either neutral cues or the cognitively appropriate semantic cues. Both verbal cues and messages were spoken in direct, phoneme-synthesized speech, and a training manipulation was included to determine the extent to which previous exposure to speech thus produced facilitates these messages' comprehension. Results are discussed in terms of the importance of human factors research in cockpit display design.

    Naito, Yusuke; Ohta, Kazuo; Kunihiro, Noboru

    In this paper, we discuss the collision search for hash functions, mainly in terms of their advanced message modification. The advanced message modification is a collision search tool based on Wang et al.'s attacks. Two advanced message modifications have previously been proposed: cancel modification for MD4 and MD5, and propagation modification for SHA-0. In this paper, we propose a new concept of advanced message modification, submarine modification. As a concrete example combining the ideas underlying these modifications, we apply submarine modification to the collision search for SHA-0. As a result, we show that this can reduce the collision search attack complexity from 239 to 236 SHA-0 compression operations.

    2016-03-01

    A 34-year-old man with manic-depressive disorder was found dead sitting in a vehicle with a hose running from the exhaust pipe to the cabin. Numerous suicide notes were found inside his house. At autopsy, the decedent was wearing jeans and a long-sleeved windcheater. Upon removal of his clothes, a series of messages were also found written on the legs and forearm. Death was due to carbon monoxide toxicity with a blood level of carboxyhemoglobin of 84%. Skin messages represent a rare form of suicide note that may suggest that a suicide has not been planned, as the decedent may have used the nearest surface to write on. This case demonstrates, however, that skin messages may be more organized, being written prior to dressing and setting up the fatal episode. They also may compliment other notes and messages.

    1995-02-01

    Portability and reliability of parallel programs can be severely impaired by their nondeterministic behavior. Therefore, an effective means to precisely and accurately specify unacceptable nondeterministic behavior is necessary for testing and debugging parallel programs. In this paper we describe a class of expressions, called Message Expressions that can be used to specify nondeterministic behavior of message passing parallel programs. Specification of program behavior with Message Expressions is easier than pattern based specification techniques in that the former does not require knowledge of run-time event order, whereas that later depends on the user`s knowledge of the run-time event order for correct specification. We also discuss our adaptation of Message Expressions for use in a dynamic distributed testing and debugging tool, called mdb, for programs written for PVM (Parallel Virtual Machine).

    WMAgent is the core component of the CMS workload management system. One of the features of this job managing platform is a configurable messaging system aimed at generating, distributing and processing alerts: short messages describing a given alert-worthy information or pathological condition. Apart from the framework's sub-components running within the WMAgent instances, there is a stand-alone application collecting alerts from all WMAgent instances running across the CMS distributed computing environment. The alert framework has a versatile design that allows for receiving alert messages also from other CMS production applications, such as PhEDEx data transfer manager. We present implementation details of the system, including its Python implementation using ZeroMQ, CouchDB message storage and future visions as well as operational experiences. Inter-operation with monitoring platforms such as Dashboard or Lemon is described.

    2015-03-18

    The aim of this systematic review of reviews is to identify mobile text-messaging interventions designed for health improvement and behavior change and to derive recommendations for practice. We have compiled and reviewed existing systematic research reviews and meta-analyses to organize and summarize the text-messaging intervention evidence base, identify best-practice recommendations based on findings from multiple reviews, and explore implications for future research. Our review found that the majority of published text-messaging interventions were effective when addressing diabetes self-management, weight loss, physical activity, smoking cessation, and medication adherence for antiretroviral therapy. However, we found limited evidence across the population of studies and reviews to inform recommended intervention characteristics. Although strong evidence supports the value of integrating text-messaging interventions into public health practice, additional research is needed to establish longer-term intervention effects, identify recommended intervention characteristics, and explore issues of cost-effectiveness.

    The increasing usage of social media for conversations, together with the availability of its data to researchers, provides an opportunity to study human conversations on a large scale. Twitter, which allows its users to post messages of up to a limit of 140 characters, is one such social media. Previous studies of utterances in books, movies and Twitter have shown that most of these utterances, when transcribed, are much shorter than 140 characters. Furthermore, the median length of Twitter messages was found to vary across US states. Here, we investigate whether the length of Twitter messages varies across different regions in the UK. We find that the median message length, depending on grouping, can differ by up to 2 characters. PMID:25853678

    Previous research using cell phones indicates that manual manipulation is not a principal component of text messaging relating driving detriment. This paper suggests that manipulation of a phone in conjunction with the cognitive need to compose the message itself co-act to contribute to driving degradation. This being so, drivers sending text messages might experience reduced interference to the driving task if the text messaging itself were assisted through the predictive T9 system. We evaluated undergraduate drivers in a simulator who drove and texted using either Assisted Text entry, via Nokia's T9 system, or unassisted entry via the multitap interface. Results supported the superiority of the T9 system over the multitap system implying that specific assistive technologies can modulate the degradation of capacity which texting tragically induces.

    Background Few experimental studies have been conducted on social determinants of pain tolerance. Purpose This study tests a brief, computer-delivered social norm message for increasing pain tolerance. Methods Healthy young adults (N=260; 44 % Caucasian; 27 % Hispanic) were randomly assigned into a 2 (social norm)×2 (challenge) cold pressor study, stratified by gender. They received standard instructions or standard instructions plus a message that contained artifically elevated information about typical performance of others. Results Those receiving a social norm message displayed significantly higher pain tolerance, F(1, 255)=26.95, p<.001, ηp2=.10 and pain threshold F(1, 244)=9.81, p=.002, ηp2=.04, but comparable pain intensity, p>.05. There were no interactions between condition and gender on any outcome variables, p>.05. Conclusions Social norms can significantly increase pain tolerance, even with a brief verbal message delivered by a video. PMID:24146086

    2015-06-01

    A short partial sequence of 28 amino acids is all the information we have so far about the putative allergen 2S albumin from almond. The aim of this work was to analyze this information using mainly bioinformatics tools, in order to verify its rightness. Based on the results reported in the paper describing this allergen from almond, we analyzed the original data of amino acids sequencing through available software. The degree of homology of the almond 12kDa protein with any other known 2S albumin appears to be much lower than the one reported in the paper that firstly described it. In a publicly available cDNA library we discovered an expressed sequence tag which translation generates a protein that perfectly matches both of the sequencing outputs described in the same paper. A further analysis indicated that the latter protein seems to belong to the vicilin superfamily rather than to the prolamin one. The fact that also vicilins are seed storage proteins known to be highly allergenic would explain the IgE reactivity originally observed. Based on our observations we suggest that the IgE reactive 12kDa protein from almond currently known as Pru du 2S albumin is in reality the cleaved N-terminal region of a 7S vicilin like protein.

Some of the crew members who survived were left with multiple small fragments of DU in their muscles and soft tissues. The number, size and location of the fragments made them inoperable in general, and therefore subject to long-term retention. Because there was inadequate data to predict the potential carcinogenicity of DU fragments in soft tissues, Hahn et al. (2003) conducted a lifespan cancer study in rats. As part of that study, a number of rats were maintained to study the biokinetics and dosimetry of DU implanted intramuscularly in male Wistar rats. Typically, four metal fragments, either as cylindrical pellets or square wafers were implanted into the biceps femoris muscles of the rats. Urine samples were collected periodically during their lifespans, and DU was analyzed in kidneys and eviscerated carcass (minus the implant sites) at death. The daily DU urinary excretion rate increased steeply during the first 30 d after implantation peaking at about 90 d at 3-10 x 10{sup -3}%/d. During the first 150 d, the average excretion rate was 2.4 x 10{sup -3}%/d, decreasing thereafter to about 1 x 10{sup -3}%/d. Serial radiographs were made of the wound sites to monitor gross morphologic changes in the DU implant and the surrounding tissue. As early as 1 w after implantation, radiographs showed the presence of surface corrosion and small, dense bodies near the original implant, presumably DU. This corrosion from the surface of the implant continued with time, but did not result in an increasing amount of DU reaching the blood and urine after the first 3 mo. During this 3-mo period, connective tissue capsules formed around the implants, and are hypothesized to have reduced the access of DU to tissue fluids by limiting the diffusion

  2. Cassini/Huygens your messages en route for Titan

    This unprecedented operation will soon be coming to an end. The Internet site will not be accepting messages after 1 March 1997, although it will remain active to incorporate regularly updated information on the Cassini/Huygens mission at least until the launch in October 1997. ESA has decided to open the site to audio messages as well until 1 March 1997. Files, which must be no larger than 250 KB, should sent to the electronic letterbox sound@huygens.com in WAV or AIFF format. We shall be concluding this exceptional operation by producing a CD-ROM containing written and audio messages within the limits of the space available. We therefore propose that all media announce the forthcoming end of the operation and stress the additional possibility of sending in audio as well as written messages that will leave for Titan in October 1997. Radio or television stations wishing to offer listeners or viewers the opportunity to transmit their messages over the air can forward them to us on audio or video (Betacam) cassettes. N.B. No more than three twenty-second messages per station. For further information, please contact : ESA Public Relations Division Tel: +33.1.53.69.71.55 Fax : +33.1.53.69.76.90

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

    Research suggests that young children have body image concerns, such as a desire for thinness and an avoidance of obesity. Surprisingly, few studies have investigated how children's body preferences and stereotypes are influenced by media aimed at children. In order to gain a better understanding of the content of such media, a content analysis was used to examine body image-related messages in popular children's videos and books. Results indicated that messages emphasizing the importance of physical appearance and portraying body stereotypes are present in many children's videos but relatively few books. Of the videos examined, the ones that exhibited the most body image-related messages were Cinderella and The Little Mermaid. Indian in the Cupboard and ET were the videos with the least number of body image-related messages. Of the books studied, the one with the highest number of body image-related messages was Rapunzel. Ginger and The Stinky Cheese Man were the only books studied that did not exhibit body image-related messages. Implications of an association of beauty and thinness in children's media are explored.

    Abstract Objective To present Cirque du Soleil’s social circus program, Cirque du Monde, to explore its potential as a primary health care tool for family physicians. Data sources A review of the literature in PubMed, the Cochrane Library, PsycINFO, LaPresse, Eureka, Google Scholar, and Érudit using the key words circus, social circus, Cirque du Monde, and Cirque du Soleil; a Montreal-based initiative, Espace Transition, modeled on Cirque du Monde; and personal communication with Cirque du Soleil’s Social Circus Training Advisor. Study selection The first 50 articles or websites identified for each key word in each of the databases were examined on the basis of their titles and abstracts in the case of articles, and on the basis of their titles and page content in the case of websites. Articles and websites that explored an aspect of social circuses or that described an intervention that involved circuses were then retained for analysis. Because all literature on social circuses was searched, no criterion for year of publication was used. Synthesis No articles on the social circus as a health intervention were found. One study on the use of the circus as an intervention in schools was identified. It demonstrated an increase in self-esteem in the children who took part. One study on the use of the circus in a First Nations community was found; it contained nonspecific, qualitative findings. The other articles identified were merely descriptions of social circuses. One website was identified on the use of the social circus to help youth who had been treated in a hospital setting for major psychiatric disorders to re-enter the community. The team in the pediatric psychiatry department at Centre Hospitalier Universitaire Sainte-Justine, the children’s hospital in Montreal, Que, was contacted; they were leading this project, called Espace Transition. The unpublished preliminary findings of its pilot project demonstrate substantial improvements in overall patient

    Adolescents and young adults use text messaging as their primary mode of communication, thus providing an opportunity to use this mode of communication for mobile health (mHealth) interventions. Youth with diabetes are an important group for these mHealth initiatives, as diabetes management requires an enormous amount of daily effort and this population has difficulty achieving optimal diabetes management. Goal setting and self-efficacy are 2 factors in the management of diabetes. We examined the feasibility of a healthy lifestyle text messaging program targeting self-efficacy and goal setting among adolescents and young adults with diabetes. Participants, ages 16-21, were assigned to either a text messaging group, which received daily motivational messages about nutrition and physical activity, or a control group, which received paper-based information about healthy lifestyle. Both groups set goals for nutrition and physical activity and completed a measure of self-efficacy. Participants' mean age was 18.7 ± 1.6 years old, with diabetes duration of 10.0 ± 4.6 years, and A1c of 8.7 ± 1.7%. The text messaging intervention was rated highly and proved to be acceptable to participants. Self-efficacy, glycemic control, and body mass index did not change over the course of the short, 1-month pilot study. Positive, daily, motivational text messages may be effective in increasing motivation for small goal changes in the areas of nutrition and physical activity. These interventions may be used in the future in youth with diabetes to improve diabetes care. Utilizing more targeted text messages is an area for future research. PMID:25172879

    The purpose of this study was to examine if messages tailored to an individual’s regulatory focus (i.e. their tendency to focus on prevention or promotion) increased exercise intentions and behavior in a medically underserved sample. Adult English as a Second Language students (N = 58) were presented with tailored exercise messages. There was a significant main effect for message type; participants who received promotion messages reported greater exercise intentions than those who received prevention messages. Intentions and behavior were not higher among those who received messages matching their regulatory focus. Implications for message tailoring frameworks are discussed. PMID:22689590

    Because implicit evaluations are thought to underlie many aspects of behavior, researchers have started looking for ways to change them. We examine whether and when persuasive messages alter strongly held implicit evaluations of smoking. In smokers, an affective anti-smoking message led to more negative implicit evaluations on four different implicit measures as compared to a cognitive anti-smoking message which seemed to backfire. Additional analyses suggested that the observed effects were mediated by the feelings and emotions raised by the messages. In non-smokers, both the affective and cognitive message engendered slightly more negative implicit evaluations. We conclude that persuasive messages change implicit evaluations in a way that depends on properties of the message and of the participant. Thus, our data open new avenues for research directed at tailoring persuasive messages to change implicit evaluations. PMID:26557099

    Upper limp hyperhydrosis is an idiopathic disease with bilateral involvement. However, Pourfour du Petit syndrome, the opposite of Horner syndrome, may result in unilateral upper limb hyperhydrosis. It occurs following hyperactivity of the sympathetic cervical chain as a consequence of irritation secondary to trauma. We report herein two cases with Pourfour du Petit syndrome showing unilateral upper limb hyperhydrosis. The patients presented with right-sided mydriasis and ipsilateral hemifacial hyperhydrosis. The onset of disease was followed by a trauma in both patients. They underwent upper thoracic sympathectomy with favorable outcome. A history of an antecedent trauma in patients with unilateral upper limb hyperhydrosis and anisocoria may imply a possible diagnosis of Pourfour du Petit syndrome. PMID:15296919

    Background Adherence to childhood immunization schedules is a function of various factors. Given the increased use of technology as a strategy to increase immunization coverage, it is important to investigate how parents perceive different forms of communication, including traditional means and text-message reminders. Objective To examine current forms of communication about immunization information, parents’ satisfaction levels with these communication modes, perceived barriers and benefits to using text messaging, and the ideal content of text messages for immunization reminders. Methods Structured interviews were developed and approved by two Institutional Review Boards. A convenience sample of 50 parents was recruited from two local pediatric clinics. The study included a demographics questionnaire, the shortened form of the Test of Functional Health Literacy for Adults (S-TOFHLA), questions regarding benefits and barriers of text communication from immunization providers, and preferred content for immunization reminders. Content analyses were performed on responses to barriers, benefits, and preferred content (all Cohen’s kappas > 0.70). Results Respondents were mostly female (45/50, 90%), white non-Hispanic (31/50, 62%), between 20–41 years (mean = 29, SD 5), with one or two children (range 1–9). Nearly all (48/50, 96%) had an S-TOFHLA score in the “adequate” range. All parents (50/50, 100%) engaged in face-to-face contact with their child’s physician at appointments, 74% (37/50) had contact via telephone, and none of the parents (0/50, 0%) used email or text messages. Most parents were satisfied with the face-to-face (48/50, 96%) and telephone (28/50, 75%) communication. Forty-nine of the 50 participants (98%) were interested in receiving immunization reminders by text message, and all parents (50/50, 100%) were willing to receive general appointment reminders by text message. Parents made 200 comments regarding text-message reminders. Benefits

    Cigarette smoking is the primary preventable cause of mortality and morbidity in the US. But in the mid-1990s, more than one-third of US teenagers were smokers, despite their awareness of the health risks and negative consequences of tobacco use. In 1996, as part of a three-year qualitative study to explore differences in adolescent smoking by gender and ethnicity, members of the Tobacco Control Network examined messages that teens receive about cigarette smoking. Consisting of 178 focus groups with 1,175 teenagers covering all levels of smoking experience, the study included teens from five ethnic groups, stratified by gender and ethnicity, from urban and rural areas across the US. The authors reviewed the sources and content of messages that teens reported were most influential in their decisions to smoke or not smoke cigarettes. Family and peers, school, television, and movies were the primary sources for both pro- and anti-smoking messages. The authors conclude that a lack of clear, consistent antismoking messages leaves teens vulnerable to the influences of pro-smoking messages from a variety of sources. Interventions need to be culture- and gender-specific. Family-based interventions appear to be needed and efficacious, but resource intensive. Building self-esteem may prove to be a promising intervention. PMID:11889286

    Current sun safety messages stress the importance of sun protection in avoiding the consequences of excessive exposure to ultraviolet radiation (UVR), such as skin cancers, cataracts and other eye diseases, and viral infections caused by UV-induced immunosuppression. However, adequate exposure to UVR has an important role in human health, primarily through UV-induced production of vitamin D, a hormone essential to bone health. Vitamin D insufficiency may be associated with increased risks of some cancers, autoimmune diseases and mental health disorders such as schizophrenia. Here, we review the evolution of current sun exposure practices and sun-safe messages and consider not only the benefits, but also the detrimental effects that such messages may have. UVR-induced vitamin D production can be inhibited by factors such as deep skin pigmentation, indoor lifestyles, older age, sun avoidance behaviours and clothing habits that limit skin exposure, with deleterious consequences for health. There is some early evidence that sun-safe messages are beginning to cause a decrease in skin cancer rates in young people. After the widespread promotion of sun safety, it may now be appropriate to refine public health messages to take better account of variations between groups and their susceptibility to the dangers and benefits of sun exposure.

    Communication theories and research data were used to design cross-cultural health education messages. A University of California Los Angeles-Universidad Autonoma in Tijuana, Mexico, research team used the methods of ethnographic and survey research to study behaviors, attitudes, and knowledge concerning prenatal care of a sample of pregnant low-income women living in Tijuana. This audience provided information that served as a framework for a series of messages to increase awareness and change prenatal care behaviors. The message design process was guided by persuasion theories that included Petty and Caccioppo's elaboration likelihood model, McGuire's persuasion matrix, and Bandura's social learning theory. The results from the research showed that poor women in Tijuana tend to delay or not seek prenatal care. They were not aware of symptoms that could warn of pregnancy complications. Their responses also revealed pregnant women's culturally specific beliefs and behaviors regarding pregnancy. After examination of these and other results from the study, prenatal care messages about four topics were identified as the most relevant to communicate to this audience: health services use, the mother's weight gain, nutrition and anemia, and symptoms of high-risk complications during pregnancy. A poster, a calendar, a brochure, and two radio songs were produced and pretested in focus groups with low-income women in Tijuana. Each medium included one or more messages addressing informational, attitudinal, or behavioral needs, or all three, of the target population. PMID:8497574

    Data link Air Traffic Control (ATC) and Air Traffic Service (ATS) message and data exchange offers the potential benefits of increased flight safety and efficiency by reducing communication errors and allowing more information to be transferred between aircraft and ground facilities. Digital communication also presents an opportunity to relieve the overloading of ATC radio frequencies which hampers message exchange during peak traffic hours in many busy terminal areas. A piloted simulation study to develop pilot factor guidelines and assess potential flight crew benefits and liabilities from using data link ATC message exchange was completed. The data link ATC message exchange concept, implemented on an existing navigation computer Control Display Unit (CDU) required maintaining a voice radio telephone link with an appropriate ATC facility. Flight crew comments, scanning behavior, and measurements of time spent in ATC communication activities for data link ATC message exchange were compared to similar measures for simulated conventional voice radio operations. The results show crew preference for the quieter flight deck environment and a perception of lower communication workload.

    Résumé Objectif Résumer les meilleures données portant sur les stratégies d’identification et de prise en charge des femmes qui présentent des antécédents familiaux de cancer du sein. Sources d’information Une recherche a été effectuée sur PubMed à l’aide des mots-clés anglais suivants : breast cancer, guidelines, risk, family history, management et magnetic resonance imaging screening, entre 2000 et 2016. La plupart des données sont de niveau II. Message principal Une bonne anamnèse familiale est essentielle lors de l’évaluation du risque de cancer du sein afin d’identifier les femmes qui sont candidates à une recommandation en counseling génétique pour un éventuel test génétique. On peut sauver des vies en offrant aux femmes porteuses d’une mutation au gène BRCA des interventions chirurgicales de réduction des risques (mastectomie bilatérale prophylactique, salpingo-ovariectomie bilatérale). Il faut encourager toutes les femmes qui présentent des antécédents familiaux de cancer du sein à demeurer actives et à limiter leur consommation d’alcool à moins de 1 verre par jour; certaines femmes sont admissibles à la chimioprévention. Il faut offrir aux femmes dont le risque à vie de cancer du sein est de 20 à 25 % ou plus un dépistage poussé par imagerie par résonance magnétique en plus d’une mammographie. Conclusion Une vie saine et la chimioprévention (chez les candidates) pourraient réduire l’incidence du cancer du sein; le dépistage poussé pourrait entraîner une détection plus précoce. Le fait d’aiguiller des femmes porteuses d’une mutation au BRCA vers la chirurgie de réduction des risques sauve des vies. PMID:27737991

    Background Art has been shown to be an empowering and engaging entity with numerous benefits to vulnerable populations, including the homeless persons and young adults. Yet, little is known how homeless young adults perceive the use of art as messages that can communicate the danger of initiating or continuing drug and alcohol use. Objectives The purpose of this study was to solicit perspectives of homeless drug-using young adults as to how art can be used to design messages for their peers about the danger of initiating or continuing drug and alcohol use. Methods Qualitative methodology via focus group discussions was utilized to engage 24 homeless young adults enrolled from a drop-in site in Santa Monica. Results The findings revealed support for a myriad of delivery styles, including in person communication, flyers, music, documentary film and creative writing. The young adults also provided insight into the importance of the thematic framework of messages. Such themes ranged from empowering and hopeful messages to those designed to scare young homeless adults into not experimenting with drugs. Conclusions The findings indicate that in addition to messages communicating the need to prevent or reduce drug and alcohol use, homeless young adults respond to messages that remind them of goals and dreams they once had for their future, and to content that is personal, real and truthful. . Our research indicates that messages that reinforce protective factors such as hope for the future and self-esteem may be as important to homeless young adults as information about the risks and consequences of drug use.

    The Message Generation Facility (MGF) is an element of the Galileo Mission Segment (GMS) and is responsible for real-time distribution of the navigation, integrity and SAR messages from the processing facilities (OSPF, IPF, ERIS, RLSP) to the Up-Link Stations (ULS). The main objective is to route a message to the correct ULS in time for on-board update of navigation data and integrity data for dissemination to users. The MGF element is being developed by Deimos Space S.L. (Spain). To perform the Assembly, Integration and Verification (AIV) activities of the MGF, a dedicated test platform, MGF-AIVP, is developed by the National Aerospace Laboratory, NLR (the Netherlands). The MGF-AIVP simulates other Elements in the GMS that are connected to the MGF, in real-time. Its focus is to verify the main objective of the MGF.

    While the CCSDS (Consultative Committee for Space Data Systems) File Delivery Protocol (CFDP) provides internationally standardized file transfer functionality that can offer significant benefits for deep space mission operations, not all spacecraft communication requirements are necessarily best met by file transfer. In particular, continuous event-driven asynchronous message exchange may also be useful for communications with, among, and aboard spacecraft. CCSDS has therefore undertaken the development of a new Asynchronous Message Service (AMS) standard, designed to provide common functionality over a wide variety of underlying transport services, ranging from shared memory message queues to CCSDS telemetry systems. The present paper discusses the design concepts of AMS, their applicability to deep space mission operations problems, and the results of preliminary performance testing obtained from exercise of a prototype implementation.

  6. College students' prevalence and perceptions of text messaging while driving.

    2011-07-01

    By analyzing self-reports from sample of 91 college students from the United States who are frequent drivers, the present study examined the prevalence of text messaging (or "texting") while driving and the incidence of recklessness and consequences that accompany this behavior. Analyses revealed that 91% of participants reported having used text messaging while driving, with many reporting doing so with passengers, including children, riding in their vehicles. Further, a substantial number of participants reported driving dangerously above the speed limit and drifting into other traffic lanes while texting, and many reported "sexting" and arguing via text messages while driving. However, these young drivers agreed that texting while driving is dangerous and should be illegal. These results and the limitations to the present study are discussed.

    The model provides two novel strategies for the preventive control of epidemic diseases. One approach is related to the different isolating rates in latent period and invasion period. Experiments show that the increasing of isolating rates in invasion period, as long as over 0.5, contributes little to the preventing of epidemic; the improvement of isolation rate in latent period is key to control the disease spreading. Another is a specific mechanism of message delivering and forwarding. Information quality and information accumulating process are also considered there. Macroscopically, diseases are easy to control as long as the immune messages reach a certain quality. Individually, the accumulating messages bring people with certain immunity to the disease. Also, the model is performed on the classic complex networks like scale-free network and small-world network, and location-based social networks. Results show that the proposed measures demonstrate superior performance and significantly reduce the negative impact of epidemic disease.

    Young Latino immigrant men who have sex with men (MSM) are at risk for HIV and for delayed diagnosis. A need exists to raise awareness about HIV prevention in this population, including the benefits of timely HIV testing. This project was developed through collaboration between University of WA researchers and Entre Hermanos, a community-based organization serving Latinos. Building from a community-based participatory research approach, the researchers developed a campaign that was executed by Activate Brands, based in Denver, Colorado. The authors (a) describe the development of HIV prevention messages through the integration of previously collected formative data; (b) describe the process of translating these messages into PSAs, including the application of a marketing strategy; (c) describe testing the PSAs within the Latino MSM community; and (c) determine a set of important factors to consider when developing HIV prevention messages for young Latino MSM who do not identify as gay.

    2011-01-01

    Research shows that sensational news stories as well as popular romance novels often feature themes related to important topics in evolutionary psychology. In the first of four studies described in this paper we examined the song lyrics from three Billboard charts: Country, Pop, and R&B. A content analysis of the lyrics revealed 18 reproductive themes that read like an outline for a course in evolutionary psychology. Approximately 92% of the 174 songs that made it into the Top Ten in 2009 contained one or more reproductive messages, with an average of 10.49 reproductive phrases per song. Although differences in the frequency of different themes between charts were found, further analyses showed that the most popular/bestselling songs contained significantly more reproductive messages. An analysis of the lyrics of opera arias and art songs also revealed evidence for many of the same embedded reproductive messages extending back more than 400 years. PMID:22947982

    This study evaluated antismoking advertisements in South Korean television by drawing upon a Health Communication article by Cohen, Shumate, and Gold (2007) and on Gold, Cohen, and Shumate's (2008) typology. This study examined the theories and messages in South Korean antismoking advertisements. First, South Korean antismoking advertisements primarily targeted adults. In addition, the advertisements for adults normally used statistical evidence, whereas those for adolescents often used testimonial evidence. In terms of the type of performance, narration was often used in advertisements for both adults and adolescents. Second, the most prevalent persuasive health message used social norms, whereas the most prevalent affective appeal used fear appeals. Third, antismoking advertisements in South Korea mentioned more benefits of not smoking than barriers to not smoking. This study also identified the message difference in the U.S. and South Korean antismoking advertisements. PMID:25297054

    Human papillomavirus (HPV) is the most frequently diagnosed sexually transmitted infection in the United States. It is associated with the development of cervical, anal-genital, and oral-pharyngeal cancers. The rate of HPV infection among adolescents and young adults in the United States remains high, and completion rates of an HPV vaccine series remain low. At an urban pediatric clinic, adolescent and young adult participants aged 11 to 22 years (n = 37) received text message reminders for their second and third dose of HPV vaccine over an 8-month study period. Of the participants receiving text message reminders, 14% completed the vaccine series at the optimal time, whereas 0% of an interested group (n = 43) and only 3% of a standard care group (n = 232) completed the vaccine series at the optimal time. Findings support the use of text message reminders to improve HPV vaccine series completion rates in a pediatric practice. PMID:24200295

    2002-01-01

    NASA's Deep Space Network (DSN) is critical in supporting the wide variety of operating and plannedunmanned flight projects. For day-to-day operations it relies on email communication between the three Deep Space Communication Complexes (Canberra, Goldstone, Madrid) and NASA's Jet Propulsion Laboratory. The Operations & Administrative Messaging system, based on the Microsoft Windows NTand Exchange platform, provides the infrastructure that is required for reliable, mission-critical messaging. The reliability of this system, however, is threatened by the proliferation of email viruses that continue to spread at alarming rates. A layered approach to email security has been implemented across the DSN to protect against this threat.

    Salmonellosis is one of the most common foodborne human diseases. The risk of infection can be reduced by communication campaigns. The aim of this study was to demonstrate the efficacy of a food safety message that underlines that eating well-cooked meat is an effective strategy for preventing salmonellosis. The target audience was young adults (university students). They were presented with one of two messages, a prevention message or a control message. The prevention message proved to be very effective. First, it changed the attitude toward raw or rare meat, which after having read the prevention message was evaluated less positively and more negatively. Second, intentions to eat raw or rare meat were weaker in those who read the prevention message compared with those who read the control message. Third, after the message, participants in the experimental condition, but not in the control condition, associated the self-image more with well-done meat than with raw or rare meat.

    2004-11-01

    The effect of messages about genetics on lay audiences was assessed through an experimental study that exposed participants (n = 96) to a Public Service Announcement about race, genes, and heart disease. Participants who received a message that specified either 'Whites' or 'Blacks' as the subject of the message demonstrated elevated levels of racism, genetic basis for racism, and one dimension of genetic discrimination as compared to those receiving a version of the message with no race specification or in a no-message control condition. The presentation of such messages to the public is not recommended until additional research clarifies this finding and perhaps describes mitigating vocabularies or approaches.

    2015-01-01

    Using the Activation Model of Information Exposure and Elaboration Likelihood Model as theoretical frameworks, this study explored the effects of message sensation value (MSV) and message cognition value (MCV) of antismoking public service announcements (PSAs) on ad processing and evaluation among young adults, and the difference between high sensation seekers and low sensation seekers in their perceptions and responses toward ads with different levels of sensation and cognition value. A 2 (MSV: high vs. low) × 2 (MCV: high vs. low) × 2 (need for sensation: high vs. low) mixed experimental design was conducted. Two physiological measures including skin conductance and heart rate were examined. Findings of this study show that MSV was not a distraction but a facilitator of message persuasiveness. These findings contribute to the activation model. In addition, need for sensation moderated the interaction effect of MSV and MCV on ad processing. Low sensation seekers were more likely to experience the interaction between MSV and MCV than high sensation seekers. Several observations related to the findings and implications for antismoking message designs are elaborated. Limitations and directions for future research are also outlined.

    2012-01-01

    Objectives To examine the psychometric properties of two new health literacy tests, and to evaluate score validity. Methods Adults aged 40 to 71 completed the Cancer Message Literacy Test-Listening (CMLT- Listening), the Cancer Message Literacy Test-Reading (CMLT-Reading), the REALM, the Lipkus numeracy test, a brief knowledge test (developed for this study) and five brief cognitive tests. Participants also self-reported educational achievement, current health, reading ability, ability to understand spoken information, and language spoken at home. Results Score reliabilities were good (CMLT-Listening: alpha = .84) to adequate (CMLT-Reading: alpha =.75). Scores on both CMLT tests were positively and significantly correlated with scores on the REALM, numeracy, cancer knowledge and the cognitive tests. Mean CMLT scores varied as predicted according to educational level, language spoken at home, self-rated health, self-reported reading, and self-rated ability to comprehend spoken information. Conclusions The psychometric findings for both tests are promising. Scores appear to be valid indicators of comprehension of spoken and written health messages about cancer prevention and screening. Practice Implications The CMLT-Listening will facilitate research into comprehension of spoken health messages, and together with the CMLT-Reading will allow researchers to examine the unique contributions of listening and reading comprehension to health-related decisions and behaviors.

  10. Interarrival times of message propagation on directed networks.

    PubMed

    Mihaljev, Tamara; de Arcangelis, Lucilla; Herrmann, Hans J

    2011-08-01

    One of the challenges in fighting cybercrime is to understand the dynamics of message propagation on botnets, networks of infected computers used to send viruses, unsolicited commercial emails (SPAM) or denial of service attacks. We map this problem to the propagation of multiple random walkers on directed networks and we evaluate the interarrival time distribution between successive walkers arriving at a target. We show that the temporal organization of this process, which models information propagation on unstructured peer to peer networks, has the same features as SPAM reaching a single user. We study the behavior of the message interarrival time distribution on three different network topologies using two different rules for sending messages. In all networks the propagation is not a pure Poisson process. It shows universal features on Poissonian networks and a more complex behavior on scale free networks. Results open the possibility to indirectly learn about the process of sending messages on networks with unknown topologies, by studying interarrival times at any node of the network.

    One of the challenges in fighting cybercrime is to understand the dynamics of message propagation on botnets, networks of infected computers used to send viruses, unsolicited commercial emails (SPAM) or denial of service attacks. We map this problem to the propagation of multiple random walkers on directed networks and we evaluate the interarrival time distribution between successive walkers arriving at a target. We show that the temporal organization of this process, which models information propagation on unstructured peer to peer networks, has the same features as SPAM reaching a single user. We study the behavior of the message interarrival time distribution on three different network topologies using two different rules for sending messages. In all networks the propagation is not a pure Poisson process. It shows universal features on Poissonian networks and a more complex behavior on scale free networks.

  15. A taxonomic approach to communicating maxims in interstellar messages

    NASA Astrophysics Data System (ADS)

    Vakoch, Douglas A.

    2011-02-01

    Previous discussions of interstellar messages that could be sent to extraterrestrial intelligence have focused on descriptions of mathematics, science, and aspects of human culture and civilization. Although some of these depictions of humanity have implicitly referred to our aspirations, this has not clearly been separated from descriptions of our actions and attitudes as they are. In this paper, a methodology is developed for constructing interstellar messages that convey information about our aspirations by developing a taxonomy of maxims that provide guidance for living. Sixty-six maxims providing guidance for living were judged for degree of similarity to each of other. Quantitative measures of the degree of similarity between all pairs of maxims were derived by aggregating similarity judgments across individual participants. These composite similarity ratings were subjected to a cluster analysis, which yielded a taxonomy that highlights perceived interrelationships between individual maxims and that identifies major classes of maxims. Such maxims can be encoded in interstellar messages through three-dimensional animation sequences conveying narratives that highlight interactions between individuals. In addition, verbal descriptions of these interactions in Basic English can be combined with these pictorial sequences to increase intelligibility. Online projects to collect messages such as the SETI Institute's Earth Speaks and La Tierra Habla, can be used to solicit maxims from participants around the world.

  10. The Power of Metaphor in Communicating Risk in Climate Messages

    NASA Astrophysics Data System (ADS)

    Matlock, T.; Gann, T. M.; Bergmann, T.

    2014-12-01

    Risk messages are intended to capture attention whether danger is almost certain or only a remote possibility. When used the right way, metaphor is an effective tool for getting people to pay attention to hazard and take the right course of action. Metaphor is effective because it immediately grounds what is unknown and abstract in terms what is known and concrete. For instance, when talking about a wildfire that is "swallowing up homes" we instantly understand that it is dangerous and destructive (not literally eating homes), or when talking about a drought "crippling California" we instantly know that it is leading to suboptimal agricultural and economic conditions. TV journalists often use metaphor in reporting climate information because it can vivify information. In contrast, government officials who work with risk are inclined to avoid it. The aim of this presentation is twofold: 1) to analyze and characterize types metaphors in climate discourse, especially messages about extreme wildfires and severe drought conditions, and 2) to discuss the utility of metaphor to framing risk messages for varied stakeholders across varied timescales. Many examples of risk messages in natural discourse about climate are analyzed and discussed, including examples from the TV News Archive.

  4. Statistics of Epidemics in Networks by Passing Messages

    NASA Astrophysics Data System (ADS)

    Shrestha, Munik Kumar

    Epidemic processes are common out-of-equilibrium phenomena of broad interdisciplinary interest. In this thesis, we show how message-passing approach can be a helpful tool for simulating epidemic models in disordered medium like networks, and in particular for estimating the probability that a given node will become infectious at a particular time. The sort of dynamics we consider are stochastic, where randomness can arise from the stochastic events or from the randomness of network structures. As in belief propagation, variables or messages in message-passing approach are defined on the directed edges of a network. However, unlike belief propagation, where the posterior distributions are updated according to Bayes' rule, in message-passing approach we write differential equations for the messages over time. It takes correlations between neighboring nodes into account while preventing causal signals from backtracking to their immediate source, and thus avoids "echo chamber effects" where a pair of adjacent nodes each amplify the probability that the other is infectious. In our first results, we develop a message-passing approach to threshold models of behavior popular in sociology. These are models, first proposed by Granovetter, where individuals have to hear about a trend or behavior from some number of neighbors before adopting it themselves. In thermodynamic limit of large random networks, we provide an exact analytic scheme while calculating the time dependence of the probabilities and thus learning about the whole dynamics of bootstrap percolation, which is a simple model known in statistical physics for exhibiting discontinuous phase transition. As an application, we apply a similar model to financial networks, studying when bankruptcies spread due to the sudden devaluation of shared assets in overlapping portfolios. We predict that although diversification may be good for individual institutions, it can create dangerous systemic effects, and as a result

  5. Presentation of dynamically overlapping auditory messages in user interfaces

    SciTech Connect

    Papp, A.L.

    1997-09-01

    This dissertation describes a methodology and example implementation for the dynamic regulation of temporally overlapping auditory messages in computer-user interfaces. The regulation mechanism exists to schedule numerous overlapping auditory messages in such a way that each individual message remains perceptually distinct from all others. The method is based on the research conducted in the area of auditory scene analysis. While numerous applications have been engineered to present the user with temporally overlapped auditory output, they have generally been designed without any structured method of controlling the perceptual aspects of the sound. The method of scheduling temporally overlapping sounds has been extended to function in an environment where numerous applications can present sound independently of each other. The Centralized Audio Presentation System is a global regulation mechanism that controls all audio output requests made from all currently running applications. The notion of multimodal objects is explored in this system as well. Each audio request that represents a particular message can include numerous auditory representations, such as musical motives and voice. The Presentation System scheduling algorithm selects the best representation according to the current global auditory system state, and presents it to the user within the request constraints of priority and maximum acceptable latency. The perceptual conflicts between temporally overlapping audio messages are examined in depth through the Computational Auditory Scene Synthesizer. At the heart of this system is a heuristic-based auditory scene synthesis scheduling method. Different schedules of overlapped sounds are evaluated and assigned penalty scores. High scores represent presentations that include perceptual conflicts between over-lapping sounds. Low scores indicate fewer and less serious conflicts. A user study was conducted to validate that the perceptual difficulties predicted by

    In May 1991, UNESCO and the Ministry of Education of Pakistan sponsored a Regional Workshop for the Integration of Population Education in Asia-Pacific Programme of Education for All in Islamabad, Pakistan. Prior to the workshop, resource persons and experts met to develop guidelines for participants that were geared towards curriculum and material needs and core population education messages. 1 workshop group addressed integration of population education messages into primary education and the other into literacy programs. All participants observed and analyzed the problems and needs of a Muslim community and Saidpur village. The 1st group visited primary schools and spoke to teachers. The participants agreed that population education messages should be integrated into social studies, science, languages, and religion subjects at grade levels 3-5. The messages should include population related beliefs and values, problems of population growth, small family size, responsible parenthood, sex preference, population and development, the role of elders, and improving the status of women. They tested 4 of 11 developed lesson plans. Both teachers and students were generally pleased, but believed that posters and illustrations would better the plans. The other group conducted a needs assessment survey among 27 Muslim families. Participants found 100 population related issues that needed to be addressed in literacy programs. These issues fit into 6 categories and the group focused on social and cultural values and beliefs. Participants developed materials that highlighted several topics, such as early marriage and preference for males. They used puppet shows, puzzle games, posters and discussions, and story telling with pictures to communicate the messages. Puppet shows were the most popular method among housewives.

    Often, people are able to recall a message on a particular topic for a long period of time. These memorable messages have the ability to influence behavior when they are recalled from memory long after initial exposure. Knowing the topics and sources of the messages that are remembered about breast cancer can improve the efficacy of future breast cancer outreach. To this end, 359 women completed an online survey about memorable breast cancer messages. Most women (60%) recalled a memorable message, described it, identified its source, and noted whether it had resulted in prevention or detection behaviors. Four categories of message topics emerged: early detection (37.3%), awareness (30.9%), treatment (25.8%), and prevention (6%). Furthermore, five categories of sources of these memorable messages were found: media (35.5%), friends (22.2%), family (21.6%), medical professionals (15.2%), and others (5.5%). The media were a major source of all four topics of messages, although family members, friends, and the medical community were major sources for particular message topics as well. Memorable messages originating from medical professionals were substantially more likely to motivate detection behaviors than prevention behaviors. This research demonstrates that message topic and source both play roles in determining message recall as well as in determining how memorable messages impacted behavior.

  13. Exciting Message from a Dying Monster Star

    NASA Astrophysics Data System (ADS)

    1996-03-01

    an ever-increasing rate and in the course of this process the star has swollen to its present, enormous size. Moreover, IRAS 04553-6825 is now blowing away its atmosphere. It loses material at a prodigious rate: each month, the equivalent of one Earth mass disappears into the surrounding space, at velocities of up to 25 kilometers per second. Were the mass-loss to continue in this way, the star would soon evaporate completely. It may never get that far, though. There is little doubt that, much before, it will end its life by exploding as a bright supernova. In February 1987, another star in the LMC exploded as a supernova, becoming as bright as the combined light of all the stars in the entire LMC. In fact, IRAS 04553-6825 might already have exploded some time ago, but due to the finite velocity of light - it takes the light 170,000 years to travel the distance from the LMC to us - the message about its fiery death may not have reached us yet. Our Sun is not expected to die this way; the death as a brilliant supernova is reserved for much heavier stars. Stellar dust and the existence of life Billions of years ago, the silicate-rich minerals that now make up most of the rocks and sand on Earth surrounded another dying star, similar to IRAS 04553-6825 . These minerals contain the silicon-oxide molecules which were then illuminated by the light of the red supergiant star and had shone brightly as SiO masers before they condensed into dust and were blown away into space. After many millions, perhaps even billions of years, they finally ended up in the rocks of planet Earth. Not only rocks and sand, but all things we use in daily life ultimately owe their existence to stars like IRAS 04553-6825 , ranging from the food we eat to the air we breathe, from the bicycle we drive to the brain in our head. This is because massive stars such as IRAS 04553-6825 produce heavy elements like oxygen, iron and carbon. We consist of these elements, and almost everything we use is made up

    RÉSUMÉ OBJECTIF Renseigner les médecins de première ligne au sujet de l’identification précoce, du diagnostic et du traitement du trouble panique avec ou sans agoraphobie (TP/A). QUALITÉ DES DONNÉES Les données et recommandations présentées proviennent d’une recension des écrits scientifiques réalisée via les banques de données PsycLIT, PsyINFO et MEDLINE (1985 à 2006) en utilisant les descripteurs panic disorder, psychotherapy, psychosocial treatment, treatment et pharmacotherapy. Les recommandations formulées par les auteurs s’appuient sur des données probantes provenant d’études d’excellente qualité. Les informations concernant le diagnostic et l’évaluation du TP/A proviennent d’études épidémiologiques récentes, de consensus et d’opinions d’experts. PRINCIPAL MESSAGE Le TP/A est un trouble psychiatrique souvent rencontré en médecine de première ligne, mais il est fréquemment sous-diagnostiqué et sous-traité. L’identification précoce de ce trouble demande une attention particulière aux symptômes médicalement inexpliqués et, le cas échéant, le médecin doit utiliser des questions spécifiques permettant d’identifier d’éventuelles attaques de panique et de cerner leur signification pour le patient. Le traitement de premier choix pour ce trouble est une psychothérapie d’orientation cognitivo-comportementale administrée par un psychologue ou un psychiatre spécialisé. Si de telles ressources ne sont pas disponibles, le médecin peut opter pour un traitement psychopharmacologique. CONCLUSION Les médecins de famille peuvent jouer un rôle central dans l’identification et le traitement des patients souffrant d’un TP/A. PMID:17934032

    2012-02-07

    Embodiments of the invention may be used to manage message queues in a parallel computing environment to prevent message queue deadlock. A direct memory access controller of a compute node may determine when a messaging queue is full. In response, the DMA may generate an interrupt. An interrupt handler may stop the DMA and swap all descriptors from the full messaging queue into a larger queue (or enlarge the original queue). The interrupt handler then restarts the DMA. Alternatively, the interrupt handler stops the DMA, allocates a memory block to hold queue data, and then moves descriptors from the full messaging queue into the allocated memory block. The interrupt handler then restarts the DMA. During a normal messaging advance cycle, a messaging manager attempts to inject the descriptors in the memory block into other messaging queues until the descriptors have all been processed.

    2011-01-01

    This brief report presents an innovative method for capturing the content of adolescents’ electronic communication on handheld devices: text messaging, email, and Instant Messaging. In an ongoing longitudinal study, adolescents were provided with BlackBerry devices with service plans paid by the investigators, and use of text messaging was examined when participants were 15 years old and in the 10th grade (N=175, 81 girls). BlackBerries are configured so that the content of all text messages, email messages, and Instant Messages is saved to a secure server and organized in a highly secure, searchable, online archive. This paper describes the technology used to devise this method and ethical considerations. Evidence for validity is presented, including information on use of text messaging to show that participants used these devices heavily and frequencies of profane and sexual language in a two-day sample of text messaging to demonstrate that they were communicating openly.

    The Idaho National Engineering Laboratory (INEL) is developing new methods to produce high-density aggregate (artificial rock) primarily consisting of depleted uranium oxide. The objective is to develop a low-cost method whereby uranium oxide powder (UO[sub 2], U[sub 3]O[sub ]8, or UO[sub 3]) can be processed to produce high-density aggregate pieces (DU-AGG) having physical properties suitable for disposal in low-level radioactive disposal facilities or for use as a component of high-density concrete used as shielding for radioactive materials. A commercial company, G-M Systems, conducted a design study for a manufacturing pilot plant to process DU-AGG. The results of that study are included and summarized in this report. Also explained are design considerations, equipment capacities, the equipment list, system operation, layout of equipment in the plant, cost estimates, and the proposed plan and schedule.

    The last Martian apparition was observed from Pic du Midi between October 1994 and March 1995. Earth-based observation remains the only practicable way to perform continuous surveys of the planets, as opposed to orbital (HST) or space-borne observation. A good planetary site with limited demand for observational time like the 1-m telescope at Pic du Midi provides the optimal opportunity to monitor planetary activity, including atmospheric phenomena, surface variations, and polar caps recession. For instance, HST observations of Mars during this period, though yielding a much better spatial resolution, are limited to very few sessions and do not make it possible to monitor quick processes along a whole Martian season.

  5. Sustainable growth, the DuPont way.

    PubMed

    Holliday, C

    2001-09-01

    Like many manufacturers, DuPont traditionally has grown by making more and more "stuff." And its business growth has been proportional to the amount of raw materials and energy used--as well as the resulting waste and emissions from operations. Over the years, though, DuPont became aware that cheap supplies of nonrenewable resources wouldn't be endlessly available and that the earth's ecosystems couldn't indefinitely absorb the waste and emissions of production and consumption. Chad Holliday, chairman and CEO of DuPont, believes strongly in the challenge of sustainable growth and makes the business case for it: By using creativity and scientific knowledge effectively, he says, companies can provide strong returns for shareholders and grow their businesses--while also meeting the human needs of societies around the world and reducing the environmental footprint of their operations and products. In fact, a focus on sustainability can help identify new products, markets, partnerships, and intellectual property and lead to substantial business growth. Holliday describes how DuPont developed a three-pronged strategy to translate the concept of sustainability into nuts-and-bolts business practices. Focusing on integrated science, knowledge intensity, and productivity improvement, the strategy was accompanied by a new way to measure progress quantitatively. Sustainable growth should be viewed not as a program for stepped-up environmental performance but as a comprehensive way of doing business, one that delivers tremendous economic value and opens up new opportunities. Ultimately, companies will find that they can generate substantial business value through sustainability while both enhancing the quality of life around the world and protecting the environment.

    Objective This study explores the presence and actions of an electronic cigarette (e-cigarette) brand, Blu, on Twitter to observe how marketing messages are sent and diffused through the retweet (i.e., message forwarding) functionality. Retweet networks enable messages to reach additional Twitter users beyond the sender’s local network. We follow messages from their origin through multiple retweets to identify which messages have more reach, and the different users who are exposed. Methods We collected three months of publicly available data from Twitter. A combination of techniques in social network analysis and content analysis were applied to determine the various networks of users who are exposed to e-cigarette messages and how the retweet network can affect which messages spread. Results The Blu retweet network expanded during the study period. Analysis of user profiles combined with network cluster analysis showed that messages of certain topics were only circulated within a community of e-cigarette supporters, while other topics spread further, reaching more general Twitter users who may not support or use e-cigarettes. Conclusions Retweet networks can serve as proxy filters for marketing messages, as Twitter users decide which messages they will continue to diffuse among their followers. As certain e-cigarette messages extend beyond their point of origin, the audience being exposed expands beyond the e-cigarette community. Potential implications for health education campaigns include utilizing Twitter and targeting important gatekeepers or hubs that would maximize message diffusion. PMID:26684746

    2016-01-01

    This paper investigates the design of Variable Message Signs (VMS) as a way-finding aid for road tunnel emergency evacuations. The use of the Theory of Affordances is suggested to provide recommendations on the design of VMS. A preliminary evaluation of 11 selected VMS systems was performed and 6 of them were further evaluated using an affordance-based within subject stated-preference questionnaire administered to a sample of 62 participants. Results are used to provide recommendations on the characteristics of the VMS systems, such as (1) size of the sign (large or small); (2) use of flashing lights; (3) colour scheme; (4) message coding (i.e., text, pictograms or a combination of them). The best performing VMS features for road tunnel emergency evacuation included the use of larger signs, flashing lights, the combination of emergency exit pictorial symbol in green in one panel and text in amber in the other panel.

    The complexities of product engineering frequently require teams of agents, both human and digital, working together to take a product through its life-cycle. Increasingly, manufacturers, designers and project planners belong to different design teams, in different corporate organizations in a supply network, separated by large geographic distances. This paper describes the software architecture of the Collaborative Design Studio environment we are developing to support Networked Engineering. We provide the framework enabling communications exchanged during design and manufacturing activities to be annotated with design context information and archived for future reference. We present an XML-based message model to encapsulate relationships between design context and designers' communications. As a proof-of-concept, are creating a Networked Engineering Environment with integrated email, instant messaging, collaborative work, text-editing and CAD/CAM packages.

    2013-08-01

    Iterative thresholding methods have been extensively studied as faster alternatives to convex optimization methods for solving large-sized problems in compressed sensing. A novel iterative thresholding method called LCAMP (Location Constrained Approximate Message Passing) is presented for reducing computational complexity and improving reconstruction accuracy when a nonzero location (or sparse support) constraint can be obtained from view shared images. LCAMP modifies the existing approximate message passing algorithm by replacing the thresholding stage with a location constraint, which avoids adjusting regularization parameters or thresholding levels. This work is first compared with other conventional reconstruction methods using random one-dimention signals and then applied to dynamic contrast-enhanced breast magnetic resonance imaging to demonstrate the excellent reconstruction accuracy (less than 2% absolute difference) and low computation time (5-10 s using Matlab) with highly undersampled three-dimentional data (244 × 128 × 48; overall reduction factor = 10).

A parallel programming system must support the ability to develop modules that can be {open_quotes}fitted together{close_quotes} in a variety of contexts. Although it is important to be able to reuse parallel libraries, it is also more difficult to use parallel modules in comparison to sequential module. We present a methodology for developing libraries that addresses these issues effectively. The methodology, which is embodied in the Charm system, employs message-driven execution (in contrast to traditional, receive based message passing), information sharing abstractions, the notion of branched objects, and explicit support for modules.

    The extended parallel process model (EPPM) proposes fear appeals are most effective when they combine threat and efficacy. Three studies conducted in the workplace safety context examine the use of various EPPM factors and their effects, especially multiplicative effects. Study 1 was a content analysis examining the use of EPPM factors in actual workplace safety messages. Study 2 experimentally tested these messages with 212 construction trainees. Study 3 replicated this experiment with 1,802 men across four English-speaking countries-Australia, Canada, the United Kingdom, and the United States. The results of these three studies (1) demonstrate the inconsistent use of EPPM components in real-world work safety communications, (2) support the necessity of self-efficacy for the effective use of threat, (3) show a multiplicative effect where communication effectiveness is maximized when all model components are present (severity, susceptibility, and efficacy), and (4) validate these findings with gory appeals across four English-speaking countries.

    This paper investigates the design of Variable Message Signs (VMS) as a way-finding aid for road tunnel emergency evacuations. The use of the Theory of Affordances is suggested to provide recommendations on the design of VMS. A preliminary evaluation of 11 selected VMS systems was performed and 6 of them were further evaluated using an affordance-based within subject stated-preference questionnaire administered to a sample of 62 participants. Results are used to provide recommendations on the characteristics of the VMS systems, such as (1) size of the sign (large or small); (2) use of flashing lights; (3) colour scheme; (4) message coding (i.e., text, pictograms or a combination of them). The best performing VMS features for road tunnel emergency evacuation included the use of larger signs, flashing lights, the combination of emergency exit pictorial symbol in green in one panel and text in amber in the other panel.

    For the problem of multi-class linear classification and feature selection, we propose approximate message passing approaches to sparse multinomial logistic regression (MLR). First, we propose two algorithms based on the Hybrid Generalized Approximate Message Passing (HyGAMP) framework: one finds the maximum a posteriori (MAP) linear classifier and the other finds an approximation of the test-error-rate minimizing linear classifier. Then we design computationally simplified variants of these two algorithms. Next, we detail methods to tune the hyperparameters of their assumed statistical models using Stein's unbiased risk estimate (SURE) and expectation-maximization (EM), respectively. Finally, using both synthetic and real-world datasets, we demonstrate improved error-rate and runtime performance relative to existing state-of-the-art approaches to sparse MLR.

    Breast cancer is a leading cause of cancer deaths in women. Although mammography is recognized as the most effective early detection method for breast cancer, it remains underutilized. Communications theory and practice, with its emphasis on formative research, can provide a basis for developing strategies effective in changing mammography-related behaviors. Formative research, an important component of communications planning, can offer information useful in developing suitable messages and materials. The National Cancer Institute conducted small group discussions with white and black women, ages 40 to 75, to explore their attitudes, knowledge, and beliefs about mammography. Findings reinforced the results from quantitative surveys indicating that a perceived lack of their own need for the examination, lack of a physician referral, and procrastination were the main reasons that the women reported for not having mammograms. The discussions provided detailed information about the factors that can be used to guide development of messages and materials to promote mammography use. The results indicate that strategies for messages directed to either black or white women ages 40 years and older need to stress the same key message points. The points are that all women ages 40 and older are at risk for breast cancer; breast cancer can be treated successfully if it is detected early enough; mammography can detect breast cancer before a lump can be felt by a woman or her physician; women need to follow screening guidelines for age and frequency for screening; and mammography is a low-risk, quick, and painless procedure. Communication channels to reach women should include television, newspapers, magazines, and information available in physicians' offices. PMID:2113683

    This research investigates how the impact of persuasive messages in the political domain can be improved when fit is created by subliminally priming recipients’ regulatory focus (either promotion or prevention) and by linguistic framing of the message (either strategic approach framing or strategic avoidance framing). Results of two studies show that regulatory fit: a) increases the impact of a political message favoring nuclear energy on implicit attitudes of the target audience (Study 1); and b) induces a more positive evaluation of, and intentions to vote for, the political candidate who is delivering a message concerning immigration policies (Study 2).

    2002-01-01

    During Spring / Summer 2001, a prototype white-light holographic interstellar-probe message plaque was created under Contract H-29712D of NASA Marshall Spaceflight Center (MSFC), and commercial white-light holograms were tested for space-radiation tolerance at the MSFC Space Environment Facility (SEF) in Huntsville, AL, USA. Artist C Bangs' message plaque was created at the Center for Holographic Arts in Long Island City, NY. The 57.5 X 47.5 cm rainbow hologram was delivered to MSFC after framing by Simon Liu Inc., Brooklyn, NY, USA. The prototype message plaque, which is in the collection of the MSFC Space Transportation Directorate, has six multiplexed 2-D and 3-D images representing humans, the hypothetical interstellar spacecraft, and our position in the galaxy. Consultation with John Caulfield of Fisk University, an expert in holography, revealed that micron-thick holograms not much larger than a sheet of paper could contain hundreds of thousands of images, which opens the me ssage-plaque field considerably so that work of many artists could be included. Tests of commercial holograms at up to 100 MRad of simulated solar-wind radiation were performed at MSFC / SEF. Image-quality deterioriation was monitored using the image-color- histogram of the (trademarked) Adobe Photoshop software package. No significant deterioration occurred, which is in agreement with the literature. Holographic solar sails may be a propulsive application of this technology.

  4. An iconic approach to communicating musical concepts in interstellar messages

    2010-12-01

    Some characteristics of terrestrial music may be meaningful to extraterrestrial civilizations by virtue of the connection between acoustics and mathematics—both of which might be known by technologically advanced extraterrestrial intelligence. For example, a fundamental characteristic of terrestrial polyphonic music is found the number of tones used various scales, insofar as the number of tones represents a compromise between competing musical demands; the number of tones in a scale, however, also reflects some of the perceptual characteristics of the species developing that music. Thus, in the process of communicating something about the structure of terrestrial music through interstellar messages, additional information about human perceptual and cognitive processes can also be conveyed. This paper also discusses methods for sending signals that bear information through the form of the very frequencies in which the signals are transmitted. If the challenges of creating intelligible messages are greater than often thought, the advantage of reduced conventionality of encoding the message by using an iconic format of this sort may be of significant value. Such an approach would allow the incremental introduction of musical concepts, somewhat akin to the step-by-step tutorials in mathematics and logic that form the basis of Freudenthal's Lincos.

    The universal genetic code is used by all life forms to encode biological information. It can also be used to encrypt semantic messages and convey them within organisms without anyone but the sender and recipient knowing, i.e., as a means of steganography. Several theoretical, but comparatively few experimental, approaches have been dedicated to this subject, so far. Here, we describe an experimental system to stably integrate encrypted messages within the yeast genome using a polymerase chain reaction (PCR)-based, one-step homologous recombination system. Thus, DNA sequences encoding alphabetical and/or numerical information will be inherited by yeast propagation and can be sent in the form of dried yeast. Moreover, due to the availability of triple shuttle vectors, Saccharomyces cerevisiae can also be used as an intermediate construction device for transfer of information to either Drosophila or mammalian cells as steganographic containers. Besides its classical use in alcoholic fermentation and its modern use for heterologous gene expression, we here show that baker's yeast can thus be employed in a novel Saccharomyces application (NSA) as a simple steganographic container to hide and convey messages.

  6. Telling the Climate Change Story: Framing and Messaging

    2011-12-01

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

    In 2007, the VA Connecticut Healthcare System began a home electronic messaging programme for mental health patients. During the first two years, 76 patients with diagnoses of schizophrenia, post traumatic stress disorder, depression and substance-use disorders received a home messaging device, which was connected via an ordinary telephone line. There were daily questions, which were based on disease management protocols, and included alerts, data and educational components. Patient data were sent to a nurse practitioner each day for triage and follow-up. Patients used the device for at least six months. In the six months prior to enrolment, 42 patients were hospitalized for 46 admissions. In the following six months, six patients were hospitalized for nine admissions (P < 0.0001). In the six months prior to enrolment, 47 patients had a total of 80 ER visits. In the following six months, 16 patients had a total of 32 ER visits (P < 0.0001). Questionnaire responses indicated a high level of satisfaction with the home messaging programme.

    Growing evidence from online credibility research reveals that online users rely on heuristic processes to evaluate the credibility of online information. The current paper, which is based on the construal level theory (CLT), proposes that congruency between the psychological distance of a stimulus and the way it is mentally construed can act as a heuristic for believability. According to CLT, psychologically close (e.g., spatially, temporally, socially) stimuli are represented concretely whereas psychologically distant stimuli are represented abstractly. The level of mental construals and the psychological distance of information have been shown to influence people’s truth judgments in offline contexts. This study tests whether congruency between the construal level of people’s mindsets (abstract vs. concrete) and the psychological distance implied in an online message (far vs. close) enhances message believability. By partially confirming CLT predictions, we found that believability of an online news item about a distant location increased when people maintained an abstract mindset rather than a concrete one. The effect of a concrete mindset on believability was not significant for the close psychological distance condition. Our findings provide initial evidence that congruency between the construal level of people’s mindsets and psychological distance cues in online messages can act as a heuristic for believability. We discuss the potential of applying the CLT framework to the growing literature on online cognitive heuristics in the area of online information credibility. PMID:27468272

    Previous research has highlighted brain regions associated with socioemotional processes in persuasive message encoding, whereas cognitive models of persuasion suggest that executive brain areas may also be important. The current study aimed to identify lateral prefrontal brain areas associated with persuasive message viewing and understand how activity in these executive regions might interact with activity in the amygdala and medial pFC. Seventy adolescents were scanned using fMRI while they watched 10 strongly convincing antidrug public service announcements (PSAs), 10 weakly convincing antidrug PSAs, and 10 advertisements (ads) unrelated to drugs. Antidrug PSAs compared with nondrug ads more strongly elicited arousal-related activity in the amygdala and medial pFC. Within antidrug PSAs, those that were prerated as strongly persuasive versus weakly persuasive showed significant differences in arousal-related activity in executive processing areas of the lateral pFC. In support of the notion that persuasiveness involves both affective and executive processes, functional connectivity analyses showed greater coactivation between the lateral pFC and amygdala during PSAs known to be strongly (vs. weakly) convincing. These findings demonstrate that persuasive messages elicit activation in brain regions responsible for both emotional arousal and executive control and represent a crucial step toward a better understanding of the neural processes responsible for persuasion and subsequent behavior change.

    In many cultivars of maize (Zea mays L.) red light affects root development via the photomorphogenetic pigment phytochrome. The site of perception for the light is the root cap. In the maize cultivar Merit, we investigated phytochrome-mediated events in the cap. We established that the message encoded by the phyA1 gene was most abundant in dark-grown tissue and was asymmetrically distributed in the root cap, with greatest expression in the cells which make up the central columella core of the cap. Phytochrome message was negatively autoregulated in a specific region within the root cap. This autoregulation was sensitive to very-low-fluence red light, and thus was characterized as a phytochrome-mediated, very-low-fluence event. The kinetics of message reaccumulation in the dark were also examined and compared to the kinetics of the light requirement for root gravitropism in this cultivar. Similarly, the degree of autoregulation present in two other maize cultivars with different light requirements for gravitropic sensitivity was investigated. It appears that the Merit cultivar expresses a condition of hypersensitivity to phytochrome-mediated light regulation in root tissues. We conclude that phytochrome regulates many activities within the cap, but the degree to which these activities share common phytochrome-mediated steps is not known.

    OBJECTIVES. Message tailoring, based on individual needs and circumstances, is commonly used to enhance face-to-face patient counseling. Only recently has individual tailoring become feasible for printed messages. This study sought to determine whether printed tailored recommendations addressing women's specific screening and risk status and perceptions about breast cancer and mammography are more effective than standardized printed recommendations. METHODS. Computer-assisted telephone interviews were conducted with 435 women, aged 40 to 65 years, who had visited family practice groups within the previous 2 years. Subjects were randomly allocated to receive individually tailored or standardized mammography recommendation letters mailed from physicians to patients' homes. Follow-up interviews were conducted 8 months later. RESULTS. Tailored letter recipients were more likely to remember and to have read more of their letters than standardized version recipients. After controlling for baseline status, tailored letter receipt was associated with more favorable follow-up mammography status for women with incomes below $26,000 and for Black women. CONCLUSIONS. Tailored messages are a more effective medium for physicians' mammography recommendations; tailoring may be especially important for women of low socioeconomic status. PMID:8279610

    There is increasing interest in medical text messaging interventions being used to achieve positive patient outcomes across a range of clinical research and health practice environments. Short messaging service (SMS) is a low-cost tool that provides an easy communication route to engage potentially broad populations through text messaging, and is part of the growing social trend toward increased adoption of personal communication technologies by patient populations. Testing the effectiveness and impact of various communication strategies requires navigation of a complex web of clinical and research regulations and oversight mechanisms. We describe a case study of the implementation of SMS to provide bidirectional communications between physicians and patients involved in routine care reminders to illustrate the review processes and governance structures needed. By mapping the regulatory and approval processes required to manage and steward a research study across clinical and community boundaries, we provide a guide for other translational health researchers who may utilize similar kinds of personally owned technology interventions as research tools.

    The study investigated the effects of anti-speeding messages based on protection motivation theory (PMT) components: severity, vulnerability, rewards, self-efficacy, response efficacy, and response cost, on reported speeding intentions. Eighty-three participants aged 18-25 years holding a current Australian driver's license completed a questionnaire measuring their reported typical and recent speeding behaviors. Comparisons were made between 18 anti-speeding messages used on Australian roads and 18 new anti-speeding messages developed from the PMT model. Participants reported their reactions to the 36 messages on the perceived effectiveness of the message for themselves and for the general population of drivers, and also the likelihood of themselves and other drivers driving within the speed limit after viewing each message. Overall the PMT model-derived anti-speeding messages were better than jurisdiction-use anti-speeding messages in influencing participants' reported intention to drive within the speed limit. Severity and vulnerability were the most effective PMT components for developing anti-speeding messages. Male participants reported significantly lower intention to drive within the speed limit than did female participants. However, males reported significantly higher intention to drive within the speed limit for PMT-derived messages compared with jurisdiction-based messages. Third-person effects were that males reported anti-speeding messages to be more effective for the general driving population than for themselves. Females reported the opposite effect - that all messages would be more effective for themselves than for the general driving population. Findings provided support for using a sound conceptual basis as an effective foundation for anti-speeding message development as well as for evaluating proposed anti-speeding messages on the target driver population.

    Memorable message research examines interpersonal messages “…remembered for extremely long periods of time and which people perceive as a major influence on the course of their lives” (Knapp, Stohl, & Reardon, 1981, p. 27). They can also guide actions, such as health behaviors. This exploratory research examined self-reported memorable messages about breast cancer to determine if they were framed, emphasizing either the benefits (gain-framed) or the costs (loss-framed) of a behavior. About one-fourth of the messages were framed, with most being gain-framed. The messages tended to emphasize early detection actions. Study limitations and implications for future research are discussed. PMID:22539867

    Tailoring health education messages to patients' preferences for message style is believed to increase patients' susceptibility to the given advice. This paper presents a persona-centered approach towards creating tailored health messages for chronically ill patients. A case study of tailoring messages to the preferences of patients with coronary heart disease illustrates the approach and shows the need for patient-centered data collection so that personas reflect patients' preferences. Based on these personas, a manageable set of tailored messages can be created in a step-by-step approach.

    Methods, parallel computers, and products are provided for identifying messaging completion on a parallel computer. The parallel computer includes a plurality of compute nodes, the compute nodes coupled for data communications by at least two independent data communications networks including a binary tree data communications network optimal for collective operations that organizes the nodes as a tree and a torus data communications network optimal for point to point operations that organizes the nodes as a torus. Embodiments include reading all counters at each node of the torus data communications network; calculating at each node a current node value in dependence upon the values read from the counters at each node; and determining for all nodes whether the current node value for each node is the same as a previously calculated node value for each node. If the current node is the same as the previously calculated node value for all nodes of the torus data communications network, embodiments include determining that messaging is complete and if the current node is not the same as the previously calculated node value for all nodes of the torus data communications network, embodiments include determining that messaging is currently incomplete.

    This study examined whether adolescents communicate about antisocial topics and behaviors via text messaging and how adolescents’ antisocial text message communication relates to growth in rule-breaking and aggression as reported by youth, parents, and teachers. Participants (n = 172; 82 girls) received BlackBerry devices configured to capture all text messages sent and received. Four days of text messages during the 9th grade year were coded for discussion of antisocial activities. The majority of participants engaged in at least some antisocial text message communication. Text messaging about antisocial activities significantly predicted increases in parent, teacher, and self-reports of adolescents’ rule-breaking behavior, as well as teacher and self-reports of adolescents’ aggressive behavior. Text message communication may provide instrumental information about how to engage in antisocial behavior and reinforce these behaviors as normative within the peer group. PMID:24014161

    This experiment explored how consumers evaluate electronic word-of-mouth (eWOM) messages about products. Each participant was exposed a 10-message set in a single board. Five groups were manipulated in terms of their ratios of positive and negative messages. The result showed significant differences across various sets of eWOM messages. Although more positive sets showed higher scores in many cases, this was not true in all situations, especially for the case of credibility. Involvement and prior knowledge partially moderated the relationship between the ratio of messages and the eWOM effect. The credibility of Web sites and eWOM messages can be damaged in the long run if all of the eWOM messages are positive. PMID:19072076

    A broadcast encryption scheme with personalized messages (BEPM) is a scheme in which a broadcaster transmits not only encrypted broadcast messages to a subset of recipients but also encrypted personalized messages to each user individually. Several broadcast encryption (BE) schemes allow a broadcaster encrypts a message for a subset S of recipients with public keys and any user in S can decrypt the message with his/her private key. However, these BE schemes can not provide an efficient way to transmit encrypted personalized messages to each user individually. In this paper, we propose a broadcast encryption scheme with a transmission of personalized messages. Besides, the scheme is based on multilinear maps ensure constant ciphertext size and private key size of each user and the scheme can achieve statically security. More realistically, the scheme can be applied to the Conditional Access System (CAS) of pay television (pay-TV) efficiently and safely. PMID:26629817

    Text messaging is a powerful communication tool for public health purposes, particularly because of the potential to customize messages to meet individuals’ needs. However, using text messaging to send personal health information requires analysis of laws addressing the protection of electronic health information. The Health Insurance Portability and Accountability Act (HIPAA) Security Rule is written with flexibility to account for changing technologies. In practice, however, the rule leads to uncertainty about how to make text messaging policy decisions. Text messaging to send health information can be implemented in a public health setting through 2 possible approaches: restructuring text messages to remove personal health information and retaining limited personal health information in the message but conducting a risk analysis and satisfying other requirements to meet the HIPAA Security Rule.

    Adolescents were classified as being high or low in need for cognition (NFC) (Cacioppo & Petty, 1982) and expressed their knowledge about AIDS, attitudes toward condom use, and perceived supportive norms after being exposed to a cartoon or a written message about safe sex. Both messages have a positive impact on knowledge and attitudes. Theoretically interesting is the finding that the cartoon message is more effective in bringing about change in attitudes and subjective norms than the written message for low-NFC adolescents, and that the written message is more effective than the cartoon message for high-NFC adolescents. These results are consistent with the theory-based prediction that a persuasive communication will be most effective when the format of the message is tailored to people's information-processing proclivities. The practical implications of the findings for AIDS education are discussed.

    This paper describes Message Passing Interface 1 (MPI1), a proposed library interface standard for supporting point-to-point message passing. The intended standard will be provided with Fortran 77 and C interfaces, and will form the basis of a standard high level communication environment featuring collective communication and data distribution transformations. The standard proposed here provides blocking, nonblocking, and synchronized message passing between pairs of processes, with message selectivity by source process and message type. Provision is made for noncontiguous messages. Context control provides a convenient means of avoiding message selectivity conflicts between different phases of an application. The ability to form and manipulate process groups permits task parallelism to be exploited, and is a useful abstraction in controlling certain types of collective communication.

    Because adolescent girls are being targeted on social networking sites by the tobacco industry, new online tobacco control (TC) initiatives are needed. The purpose of this interpretive descriptive study was to explore adolescent girls' perspectives on the use of social networking sites to deliver TC messages targeting young women. Focus groups were conducted with 17 girls aged 16 to 19. Seven TC messages were provided for evaluation and as context for discussion about the delivery of TC messages on social networking sites. Data were analyzed for themes, which included concerns about the effectiveness of current TC messages and the stereotypical representations of gender, factors perceived to influence the effectiveness of TC messages on social networking sites, and suggestions for enhancing the effectiveness of TC messages placed on social networking sites. Endorsement of TC messaging on social networking sites suggests that this medium is an untapped resource for smoking prevention.

    Ce present projet de recherche a permis. de creer un modele par elements finis du muscle strie humain dans le but d'etudier les mecanismes engendrant les lesions musculaires traumatiques. Ce modele constitue une plate-forme numerique capable de discerner l'influence des proprietes mecaniques des fascias et de la cellule musculaire sur le comportement dynamique du muscle lors d'une contraction excentrique, notamment le module de Young et le module de cisaillement de la couche de tissu conjonctif, l'orientation des fibres de collagene de cette membrane et le coefficient de poisson du muscle. La caracterisation experimentale in vitro de ces parametres pour des vitesses de deformation elevees a partir de muscles stries humains actifs est essentielle pour l'etude de lesions musculaires traumatiques. Le modele numerique developpe est capable de modeliser la contraction musculaire comme une transition de phase de la cellule musculaire par un changement de raideur et de volume a l'aide des lois de comportement de materiau predefinies dans le logiciel LS-DYNA (v971, Livermore Software Technology Corporation, Livermore, CA, USA). Le present projet de recherche introduit donc un phenomene physiologique qui pourrait expliquer des blessures musculaires courantes (crampes, courbatures, claquages, etc.), mais aussi des maladies ou desordres touchant le tissu conjonctif comme les collagenoses et la dystrophie musculaire. La predominance de blessures musculaires lors de contractions excentriques est egalement exposee. Le modele developpe dans ce projet de recherche met ainsi a l'avant-scene le concept de transition de phase ouvrant la porte au developpement de nouvelles technologies pour l'activation musculaire chez les personnes atteintes de paraplegie ou de muscles artificiels compacts pour l'elaboration de protheses ou d'exosquelettes.

    Le cancer du sein est actuellement le cancer le plus fréquent chez la femme, et pose un véritable problème diagnostique et thérapeutique. Le dépistage des lésions à un stade de plus en plus précoce, a permis une extension des indications du traitement conservateur radiochirurgical, qui était initialement limitées aux tumeurs de moins de 3 cm, unifocales, non inflammatoires. Par ailleurs, l'utilisation de traitements préopératoires permet d’étendre les indications du traitement conservateur à des tumeurs plus volumineuses. Parallèlement à cette extension des indications de conservation mammaire, on a observé le développement de nouvelles approches thérapeutiques notamment la chirurgie oncoplastique, technique du ganglion sentinelle et chirurgie stéréotaxique, dont les résultats initiaux sont très encouragent. A travers cette étude réalisée dans le service de gynécologie et obstétrique II du CHU HASSAN II de FES au MAROC, après l'analyse rétrospective de 16 patientes traitées par traitement conservateur et oncoplastie, nous avons voulus montrer notre aptitude a réalisé ses techniques chirurgicales et a bien prendre en charge ces patientes, mais aussi évaluer ces techniques en termes de résultat carcinologique et de résultat esthétique, aussi en terme de survie globale, survie sans métastase et en termes de récidive locale entre les plasties mammaires et les traitements usuels: mastectomie et traitement conservateur classique.

    Perceived lack of realism in alcohol advertising messages promising positive outcomes and antialcohol and antidrug messages portraying negative outcomes of alcohol consumption has been a cause for public health concern. This study examined the effects of perceived realism dimensions on personal probability estimation through identification and message minimization. Data collected from college students in U.S. Midwest in 2010 (N = 315) were analyzed with multilevel structural equation modeling. Plausibility and narrative consistency mitigated message minimization, but they did not influence identification. Factuality and perceptual quality influenced both message minimization and identification, but their effects were smaller than those of typicality. Typicality was the strongest predictor of probability estimation. Implications of the results and suggestions for future research are provided.

    Background Mobile messaging interventions have been shown to improve outcomes across a number of mental health and health-related conditions, but there are still significant gaps in our knowledge of how to construct and deliver the most effective brief messaging interventions. Little is known about the ways in which subtle linguistic variations in message content can affect user receptivity and preferences. Objective The aim of this study was to determine whether any global messaging preferences existed for different types of language content, and how certain characteristics moderate those preferences, in an effort to inform the development of mobile messaging interventions. Methods This study examined user preferences for messages within 22 content groupings. Groupings were presented online in dyads of short messages that were identical in their subject matter, but structurally or linguistically varied. Participants were 277 individuals residing in the United States who were recruited and compensated through Amazon’s Mechanical Turk (MTurk) system. Participants were instructed to select the message in each dyad that they would prefer to receive to help them achieve a personal goal of their choosing. Results Results indicate global preferences of more than 75% of subjects for certain types of messages, such as those that were grammatically correct, free of textese, benefit-oriented, polite, nonaggressive, and directive as opposed to passive, among others. For several classes of messages, few or no clear global preferences were found. There were few personality- and trait-based moderators of message preferences, but subtle manipulations of message structure, such as changing “Try to…” to “You might want to try to…” affected message choice. Conclusions The results indicate that individuals are sensitive to variations in the linguistic content of text messages designed to help them achieve a personal goal and, in some cases, have clear preferences for

    Summary Background Excitement around the adoption of electronic communication between physicians and patients is tempered by the possibility of increased clinical and legal risk. If patients do not read messages in a timely fashion, duplicative communication efforts may be required and patient safety may be jeopardized. Objective We sought to assess the prevalence and risk profile of unread messages in a mature patient portal. Methods We analyzed six years of messages (2005–2010) from physicians to patients to determine the prevalence and associated characteristics of unread messages in a patient portal. We focused on clinical messages, and excluded announcements. Because some physicians sent clinical messages to groups of patients, we labeled messages sent to more than 5 patients as “outreach” messages and excluded them from general analyses. We performed a chart review of 75 clinical messages to assess for harm. Results We found that 3% of clinical messages were unread after 21 days. Messages arriving outside of business hours were slightly more likely to go unread (RR 1.15 95% CI 1.11–1.19). Patients who were male (OR 1.14 CI 1.04–1.26) African American (OR 1.69 CI 1.29–2.22) or Hispanic (OR 1.74 CI 1.17–2.59), or in the lowest income group (OR 1.72 CI 1.19–2.49) were more likely to have unread messages. Chart review showed no evidence of harm, but 13% of sampled unread messages were associated with potential delays in care. Incidentally, we found 50% of the physician-initiated outreach messages were unread. Conclusions Overall, secure messaging appears a safe form of communication, but systems to notify senders when messages are unread may have value. While most clinical messages were read, many outreach messages were not, providing caution for relying on such systems for information dissemination. Similar to other studies, differences by race and income were observed and require further study. PMID:26171082

  15. NMACA Approach Used to Build a Secure Message Authentication Code

    Alosaimy, Raed; Alghathbar, Khaled; Hafez, Alaaeldin M.; Eldefrawy, Mohamed H.

    Secure storage systems should consider the integrity and authentication of long-term stored information. When information is transferred through communication channels, different types of digital information can be represented, such as documents, images, and database tables. The authenticity of such information must be verified, especially when it is transferred through communication channels. Authentication verification techniques are used to verify that the information in an archive is authentic and has not been intentionally or maliciously altered. In addition to detecting malicious attacks, verifying the integrity also identifies data corruption. The purpose of Message Authentication Code (MAC) is to authenticate messages, where MAC algorithms are keyed hash functions. In most cases, MAC techniques use iterated hash functions, and these techniques are called iterated MACs. Such techniques usually use a MAC key as an input to the compression function, and this key is involved in the compression function, f, at every stage. Modification detection codes (MDCs) are un-keyed hash functions, and are widely used by authentication techniques such as MD4, MD5, SHA-1, and RIPEMD-160. There have been new attacks on hash functions such as MD5 and SHA-1, which requires the introduction of more secure hash functions. In this paper, we introduce a new MAC methodology that uses an input MAC key in the compression function, to change the order of the message words and shifting operation in the compression function. The new methodology can be used in conjunction with a wide range of modification detection code techniques. Using the SHA-1 algorithm as a model, a new (SHA-1)-MAC algorithm is presented. The (SHA-1)-MAC algorithm uses the MAC key to build the hash functions by defining the order for accessing source words and defining the number of bit positions for circular left shifts.

    Communications: what is it all about and why is it important? How can learning simple communications techniques increase understanding of your work, while not taking up more of your time and limited resources? Can better communications lead to improved interactions with public audiences? Given the recent focus on ocean issues by the U.S. National Commission on Ocean Policy, and increased coverage in the media on ocean science and discovery (see this summer's cover story in Newsweek, for example), better communication skills in the scientific community are more important than ever. As experts, scientists are being asked to help the American public make important decisions that will impact the ocean, the scientific community, and the public. At the same time, scientists want an informed public to value their work and the scientific process. A recent opinion poll conducted by Edge Research of American attitudes toward the ocean found that the American public trusts scientists a great deal - in fact, scientists are the most trusted group to convey information about the oceans. Interestingly, though, over half (61%) of those polled believed that citizens and scientists disagreed on the issues facing the ocean. More disturbing, a plurality (42%) said that government should focus on citizens' concerns rather than those of scientists (37%). Better communications can lead to greater understanding and acceptance of ocean sciences. This presentation will offer participants specific examples and techniques that are proven to improve communications - and make communicating less onerous. By constructing a simple "message box," scientists can learn to easily tailor their messages to specific audiences (media, policy makers, other scientists, teachers, students, and the public), simplify their messages and communicate their thoughts more clearly and easily with less effort. Additionally, examples of simple ways to effectively engage the media will also be presented. Learn how

    The U.S. Geological Survey (USGS) and partners are transitioning from test-user trials of a demonstration earthquake early warning system (ShakeAlert) to deciding and preparing how to implement the release of earthquake early warning information, alert messages, and products to the public and other stakeholders. An earthquake early warning system uses seismic station networks to rapidly gather information about an occurring earthquake and send notifications to user devices ahead of the arrival of potentially damaging ground shaking at their locations. Earthquake early warning alerts can thereby allow time for actions to protect lives and property before arrival of damaging shaking, if users are properly educated on how to use and react to such notifications. A collaboration team of risk communications researchers and earth scientists is researching the effectiveness of a chosen subset of potential earthquake early warning interface designs and messages, which could be displayed on a device such as a smartphone. Preliminary results indicate, for instance, that users prefer alerts that include 1) a map to relate their location to the earthquake and 2) instructions for what to do in response to the expected level of shaking. A number of important factors must be considered to design a message that will promote appropriate self-protective behavior. While users prefer to see a map, how much information can be processed in limited time? Are graphical representations of wavefronts helpful or confusing? The most important factor to promote a helpful response is the predicted earthquake intensity, or how strong the expected shaking will be at the user's location. Unlike Japanese users of early warning, few Californians are familiar with the earthquake intensity scale, so we are exploring how differentiating instructions between intensity levels (e.g., "Be aware" for lower shaking levels and "Drop, cover, hold on" at high levels) can be paired with self-directed supplemental

    We completed a systematic review of the literature to characterize the impact of text messaging interventions on medication adherence or mental health related outcomes in people with mental health disorders including substance use. Four electronic databases were searched from January 1999 to October 2015. Seven studies met our inclusion criteria: three studies evaluated text messaging in patients with schizophrenia or schizoaffective disorder diagnosis, two studies evaluated text messaging in patients with chronic alcohol dependence, and two studies reviewed text messaging in patients with mood disorders. Six studies were randomized controlled trials and one was a prospective pilot study with pre-post intervention design. Text messaging frequency ranged from once weekly to twelve per day. The effect of text messaging on medication adherence was measured in five studies; one study reporting significant improvements in the text messaging intervention group. The effect of text messaging on mental health related outcomes was measured in all seven studies, with five studies showing significant improvements in a variety of psychiatric and social functioning assessments. Collectively, these studies suggest text messaging is a promising tool to support management of patients with mental illness. Further research examining theory-based text messaging interventions in larger samples of patients is required.

    Human papillomavirus (HPV) vaccination is routinely recommended for U.S. adolescents ages 11 to 12 years, yet vaccine coverage remains low. Text message HPV immunization reminders to parents have been effective with increasing uptake, but text messages directly to adolescents in order to increase HPV vaccination uptake are unknown. The purpose of this study was to examine the acceptability of text messages about HPV vaccination and message preferences among adolescents. Middle school students (n = 43) assisted in designing text messages to promote HPV vaccine among their peers. Through seven focus groups and two in-class surveys, we assessed students' knowledge of HPV vaccine, use of texting, and preferences for text messages and sources. The average age of participants was 13 years, and all were White (17 males, 26 females) in this rural setting. More than 70% used text messaging with a cell phone. The text message with the best composite score (M = 2.33, SD = 0.72) for likeability, trustworthiness, and motivation to seek more information was a gain frame emphasizing reduction in HPV infection if vaccinated against HPV. Text messages with lower scores emphasized threats of disease if not vaccinated. Participants (68%) preferred doctors as their information source. Text messaging to adolescents may be a strategy to improve HPV knowledge and vaccination.

    The number of text messaging interventions designed to initiate and support behavioral health changes have been steadily increasing over the past 5 years. Messaging interventions can be tailored and adapted to an individual's needs in their natural environment-fostering just-in-time therapies and making them a logical intervention for addiction continuing care. This study assessed the acceptability of using text messaging for substance abuse continuing care and the intervention preferences of individuals in substance abuse treatment in order to develop an interactive mobile text messaging intervention. Fifty individuals enrolled in intensive outpatient substance abuse treatment completed an assessment battery relating to preferred logistics of mobile interventions, behavior change strategies, and types of messages they thought would be most helpful to them at different time points. Results indicated that 98% participants were potentially interested in using text messaging as a continuing care strategy. Participants wrote different types of messages that they perceived might be most helpful, based on various hypothetical situations often encountered during the recovery process. Although individuals tended to prefer benefit driven over consequence driven messages, differences in the perceived benefits of change among individuals predicted message preference. Implications for the development of mobile messaging interventions for the addictions are discussed. (PsycINFO Database Record (c) 2013 APA, all rights reserved).

    Background A growing body of evidence demonstrates that text messaging-based programs (short message service [SMS]) on mobile phones can help people modify health behaviors. Most of these programs have consisted of automated and sometimes interactive text messages that guide a person through the process of behavior change. Objective This paper provides guidance on how to develop text messaging programs aimed at changing health behaviors. Methods Based on their collective experience in designing, developing, and evaluating text messaging programs and a review of the literature, the authors drafted the guide. One author initially drafted the guide and the others provided input and review. Results Steps for developing a text messaging program include conducting formative research for insights into the target audience and health behavior, designing the text messaging program, pretesting the text messaging program concept and messages, and revising the text messaging program. Conclusions The steps outlined in this guide may help in the development of SMS-based behavior change programs. PMID:26690917

  4. New Message Differences for Collision Attacks on MD4 and MD5

    Sasaki, Yu; Wang, Lei; Kunihiro, Noboru; Ohta, Kazuo

    In 2005, collision resistance of several hash functions was broken by Wang et al. The strategy of determining message differences is the most important part of collision attacks against hash functions. So far, many researchers have tried to analyze Wang et al.'s method and proposed improved collision attacks. Although several researches proposed improved attacks, all improved results so far were based on the same message differences proposed by Wang et al. In this paper, we propose new message differences for collision attacks on MD4 and MD5. Our message differences of MD4 can generate a collision with complexity of less than two MD4 computations, which is faster than the original Wang et al.'s attack, and moreover, than the all previous attacks. This is the first result that improves the complexity of collision attack by using different message differences from Wang et al.'s. Regarding MD5, so far, no other message difference from Wang et al.'s is known. Therefore, study for constructing method of other message differences on MD5 should be interesting. Our message differences of MD5 generates a collision with complexity of 242 MD5 computations, which is slower than the latest best attack. However, since our attack needs only 1 bit difference, it has some advantages in terms of message freedom of collision messages.

    There will always be a new latest and greatest architecture for satellite ground systems. This paper discusses the use of a proven message-oriented middleware (MOM) architecture using publish/subscribe functions and the strengths it brings to these mission critical systems. An even newer approach gaining popularity is Service Oriented Architectures (SOAs). SOAs are generally considered more powerful than the MOM approach and address many mission-critical system challenges. A MOM vs SOA discussion can highlight capabilities supported or enabled by the underlying architecture and can identify benefits of MOMs and SOAs when applied to differing sets of mission requirements or evaluation criteria.

    Quantum signature (QS) is used to authenticate the identity of the originator, ensure data integrity and provide non-repudiation service with unconditional security. Depending on whether a trusted third party named arbitrator is involved or not, QS is classified as arbitrated QS and true QS. This paper studies existence problem about the two kinds of QS and contributes to two points: (1) a basic framework is provided to analyze the possibility of arbitrated QS on signing quantum messages; (2) disagreement between the impossibility of true QS and an existing true QS scheme is solved.

    Electronic cigarettes (e-cigarettes) are perceived as an alternative to standard tobacco cigarette smoking, primarily because of the e-cigarette industry's marketing messages. However, scientific studies about e-cigarette safety and efficacy remain limited. This column presents some of the issues associated with e-cigarette use, such as potential components of regulation, perceptions that e-cigarettes can help users quit smoking, and free-wheeling marketing strategies that include expanding e-cigarette use to young people. Nurses can be a reliable source of information about e-cigarettes.

    Current systems and protocols for integrity and authenticity verification of media data do not distinguish between legitimate signal transformation and malicious tampering that manipulates the content. Furthermore, they usually provide no localization or assessment of the relevance of such manipulations with respect to human perception or semantics. We present an algorithm for a robust message authentication code (RMAC) to verify the integrity of audio recodings by means of robust audio fingerprinting and robust perceptual hashing. Experimental results show that the proposed algorithm provides both a high level of distinction between perceptually different audio data and a high robustness against signal transformations that do not change the perceived information.

    Survivors of traumatic brain injury often lose their ability to use natural speech to communicate and then rely on augmentative and alternative communication (AAC) devices. Survivors may also have concomitant cognitive communication disorders that negatively impact memory and organization skills. AAC devices need to incorporate a word retrieval organization strategy that is fast and effective. The current study compared the conditions of topic, place, and alphabet for message recognition. The participants were asked a delayed recall question to elicit a communicative response. Results showed that alphabet is significantly more accurate than place and significantly faster than place and topic. However, participants chose to retrieve words using all three strategies.

    We predicted that mood would moderate the relation between message framing and two outcome variables, message evaluation and behavioral intention, when the message was personally relevant to the target audience. Participants (N = 242) were randomly assigned to an experimental condition in which a positive or negative mood was induced. Participants then read and evaluated a health message that emphasized potential benefits or risks associated with a vaccine. As predicted, participants who received a loss-framed message reported higher message evaluation and intention scores but only when the message was personally relevant and they were in a positive mood.

  15. Mesure du taux de la capture radiative du muon par l'hydrogene liquide

    Jonkmans, Guy

    À basse énergie, l'interaction faible entre leptons et quarks est décrite par une interaction de la forme courant × courant de type V - A. La présence de l'interaction forte induit des couplages additionnels qui doivent être déterminés expérimentalement. De ceux-ci, le couplage pseudoscalaire induit, gp , est mesuré avec la plus grande incertitude et fait l'objet de la présente recherche. L'hypothèse du Courant Axial Partiellement Conservé (CAPC) et l'usage de la relation de Goldberger-Treiman relie gp au couplage axial ga . Cette relation a été vérifiée traditionnellement par la Capture Ordinaire du Muon (COM) à une valeur fixe du moment de transfert q. La Capture Radiative du Muon (CRM), m- p-->nnmg , est un meilleur outil pour l'étude de gp à cause de sa dépendance variable en q2 qui offre une plus grande sensibilité dans la partie à haute énergie du spectre des photons. Toutefois, le petit rapport d'embranchement (~10-8) de la CRM par rapport à la désintégration du muon a retardé cette mesure jusqu'à ce jour. La théorie et les difficultés expérimentales associées à la détection des photons de CRM sont présentées au deuxième chapitre. On décrit ensuite, au troisième chapitre, les composantes du système de détection. Ce détecteur est un spectromètre à paires de grand angle solide (~3p) et qui permet l'observation des photons par l'analyse des électrons et des positrons de photo-conversion. Ainsi, le bruit de fond important des neutrons de la COM ne constitue pas un problème pour cette mesure. Nous décrivons, au quatrième chapitre, toutes les étapes de l'analyse, nécessaires pour la réduction des multiples bruits de fond. Le cinquième chapitre présente le calcul des efficacités ainsi que l'estimation des erreurs systématiques. Le sixième chapitre démontre comment l'on extrait le rapport d'embranchement pour la CRM ainsi que la valeur ae gp . On insiste sur la dépendance de gp en fonction de la valeur de

    We carry a long term survey of the solar activity with our coronagraphic system at Pic du Midi de Bigorre in the French Pyrenees (CLIMSO). It is a set of two solar telescopes and two coronagraphs, taking one frame per minute for each of the four channels : Solar disk in H-α (656.28 nm), prominences in H-α, disk in Ca II (393.3 nm), prominences in He I (1083 nm), all year long, weather permitting. Since 2015 we also take images of the FeXIII corona (1074.7 nm) at the rate of one every 10 minutes. These images cover a large field: 1.25 solar diameter, 2k*2K pixels, and are freely downloadable form a database. The improvements made since 2015 concern an autoguiding system for better centering of the solar disk behind the coronagraphic masks, and a new Fe XIII channel at λ=1074.7 nm. In the near future we plan to provide radial velocity maps of the disc and polarimetry maps of the disk and corona. This survey took its present form in 2007 and we plan to maintain image acquisition in the same or better experimental conditions for a long period: one or several solar cycles if possible. During the partial solar eclipse of March 20, 2015, the CLIMSO instruments and the staff at Pic du Midi operating it have provided several millions internet users with real time images of the Sun and Moon during all the phenomenon.

    Résumé Question Des enfants qui fréquentent ma clinique ont des épisodes semblables à des convulsions pendant lesquels ils pleurent et retiennent leur souffle au point de faire survenir une cyanose et de perdre conscience. Les résultats à l’examen ou aux investigations sont normaux et les pédiatres consultés ne font pas d’autres investigations. Les spasmes du sanglot sont-ils communs et quels genres d’investigations faut-il faire? Réponse Le spasme du sanglot est un trouble non épileptique paroxysmal bénin qui se produit chez les enfants en santé de six à 48 mois. Les épisodes commencent par une provocation, comme un bouleversement émotionnel ou une blessure mineure, et peuvent progresser en une retenue de la respiration, une cyanose et une syncope. Les épisodes sont extrêmement effrayants à regarder mais ont des conséquences bénignes. Une fois le diagnostic clinique posé, on recommande de faire passer un électrocardiogramme et d’exclure la possibilité d’une anémie, mais aucune autre investigation ou demande de consultation n’est nécessaire.

    We analyzed purification mechanisms of silicon by inductive plasma with a fluoride slag. The aim is to study boron elimination from doped electronic grade silicon in function of the nature of the slag to obtain a photovoltaic grade silicon. The steady began with the calculation and the comparison of the stability diagram of boron compounds in presence of CaF2, BaF2 and MgF2. This study led us to conclude that BaF2 is the better slag for silicon purification. This has been confirmed by experience. In a second time, we made purifications under electric bias to enhance slag efficiency. We noticed that BaF2 is more sensitive to electric bias than other slags. Nous avons analysé le mécanisme de purification du silicium sous plasma inductif en présence d'un laitier fluoré. L'objectif principal est d'étudier l'élimination du bore du silicium électronique dopé en fonction de la nature du fluorure pour obtenir un silicium de qualité photovoltaïque. L'étude a commencé par l'établissement et la comparaison de diagrammes des composés du bore en présence de CaF2, de MgF2 et de BaF2. Nous avons déduit de cette première étude que BaF2 est le meilleur laitier pour la purification du silicium. Ceci a été corroboré par l'expérience. Nous avons ensuite opéré en présence d'un champ électrique dans le but d'améliorer encore l'efficacité des laitiers. Nous avons constaté que BaF2 est plus sensible au champ électrique que les deux autres laitiers utilisés.

  19. Synchronicity, instant messaging, and performance among financial traders

    Successful animal systems often manage risk through synchronous behavior that spontaneously arises without leadership. In critical human systems facing risk, such as financial markets or military operations, our understanding of the benefits associated with synchronicity is nascent but promising. Building on previous work illuminating commonalities between ecological and human systems, we compare the activity patterns of individual financial traders with the simultaneous activity of other traders—an individual and spontaneous characteristic we call synchronous trading. Additionally, we examine the association of synchronous trading with individual performance and communication patterns. Analyzing empirical data on day traders’ second-to-second trading and instant messaging, we find that the higher the traders’ synchronous trading is, the less likely they are to lose money at the end of the day. We also find that the daily instant messaging patterns of traders are closely associated with their level of synchronous trading. This result suggests that synchronicity and vanguard technology may help traders cope with risky decisions in complex systems and may furnish unique prospects for achieving collective and individual goals.

    Sensation information is proposed as a way of decreasing the patient's distress during a threatening health care event. A first step in developing a sensation information message is to determine the content of the message. This study, using a systematic theory-based methodology, was conducted to describe and validate the common physical sensations experienced by patients undergoing the diagnostic procedure of femoral arteriography. (A conceptual framework based on how an individual perceives or senses a situation was used.) A three-stage survey design was used including: (1) tool development following observation of the procedure and pilot-testing of the interview schedule, (2) interview of patients who had undergone femoral arteriography about the sensations experienced during the procedure, and (3) validation of the responses. Twenty-one steps in the femoral arteriography procedure of which patients were aware were identified. Nine 'feeling' sensations commonly experienced during the procedure and the sights and sounds associated with the procedure were determined. The sequencing and duration of procedure steps were observed and the environment in which the procedure was performed was described.
