    The CMS Communications Group, established at the start of 2010, has been busy in all three areas of its responsibility: (1) Communications Infrastructure, (2) Information Systems, and (3) Outreach and Education. Communications Infrastructure There are now 55 CMS Centres worldwide that are well used by physicists working on remote CMS shifts, Computing operations, data quality monitoring, data analysis and outreach. The CMS Centre@CERN in Meyrin, is the centre of the CMS offline and computing operations, hosting dedicated analysis efforts such as during the CMS Heavy Ion lead-lead running. With a majority of CMS sub-detectors now operating in a “shifterless” mode, many monitoring operations are now routinely performed from there, rather than in the main Control Room at P5. The CMS Communications Group, CERN IT and the EVO team are providing excellent videoconferencing support for the rapidly-increasing number of CMS meetings. In parallel, CERN IT and ...

Communications Infrastructure The 55 CMS Centres worldwide are well used by physicists working on remote CMS shifts, Computing operations, data quality monitoring, data analysis and outreach. The CMS Centre@CERN in Meyrin, is the centre of the CMS Offline and Computing operations, and a number of subdetector shifts can now take place there, rather than in the main Control Room at P5. A new CMS meeting room has been equipped for videoconferencing in building 42, next to building 40. Our building 28 meeting room and the facilities at P5 will be refurbished soon and plans are underway to steadily upgrade the ageing equipment in all 15 CMS meeting rooms at CERN. The CMS evaluation of the Vidyo tool indicates that it is not yet ready to be considered as a potential replacement for EVO. The Communications Group provides the CMS-TV (web) cha...

      Outreach and Education We are fortunate that our research has captured the public imagination, even though this inevitably puts us under the global media spotlight, as we saw with the Higgs seminar at CERN in December, which had 110,000 distinct webcast viewers. The media interest was huge with 71 media organisations registering to come to CERN to cover the Higgs seminar, which was followed by a press briefing with the DG and Spokespersons. This event resulted in about 2,000 generally positive stories in the global media. For this seminar, the CMS Communications Group prepared up-to-date news and public material, including links to the CMS results, animations and event displays [http://cern.ch/go/Ch8thttp://cern.ch/go/Ch8t]. There were 44,000 page-views on the CMS public website, with the Higgs news article being by far the most popular item.

    Unlike many other operating systems, Amoeba is a distributed operating system that provides group communication (i.e. one-to-many communication). The authors discuss design issues for group communication, Amoeba's group system calls, and the protocols to implement group communication. To demonstrate that group communication is a useful abstraction, they describe a design and implementation of a fault-tolerant directory service. They discuss two versions of the directory service: one with non-volatile RAM (NVRAM) and one without NVRAM. They give performance figures for both implementations.

    Full Text Available This paper presents MTor, a low-latency anonymous group communication system. We construct MTor as an extension to Tor, allowing the construction of multi-source multicast trees on top of the existing Tor infrastructure. MTor does not depend on an external service to broker the group communication, and avoids central points of failure and trust. MTor’s substantial bandwidth savings and graceful scalability enable new classes of anonymous applications that are currently too bandwidth-intensive to be viable through traditional unicast Tor communication-e.g., group file transfer, collaborative editing, streaming video, and real-time audio conferencing.

    2001-01-01

    The quality and benefit of college English teaching is, to some extent, decided by what methodological approach it employs. The current teaching syllabus adopts the communicative approach, which is well established as the dominant theoretical model in college English teaching. This paper tries to discuss these characteristics and explain why the model, procedure and links of college English teaching in the classroom are so vital to improve the language and communicative abilities of students. The teaching methods cannot and should not be fixed. It is restricted by the English levels and learning strategies of students,and by the academic quality and teaching ideas of teachers. A good teacher is such and flexibly to help his students attain the goal that syllabus demands.

  14. Learning to communicate risk information in groups

    Directory of Open Access Journals (Sweden)

    Hsuchi Ting

    2008-12-01

    Full Text Available Despite vigorous research on risk communication, little is known about the social forces that drive these choices. Erev, Wallsten, and Neal (1991 showed that forecasters learn to select verbal or numerical probability estimates as a function of which mode yields on average the larger group payoffs. We extend the result by investigating the effect of group size on the speed with which forecasters converge on the better communication mode. On the basis of social facilitation theory we hypothesized that small groups induce less arousal and anxiety among their members than do large groups when performing new tasks, and therefore that forecasters in small groups will learn the better communication mode more quickly. This result obtained in Experiment 1, which compared groups of size 3 to groups of size 5 or 6. To test whether social loafing rather than social facilitation was mediating the effects, Experiment 2 compared social to personal feedback holding group size constant at 3 members. Learning was faster in the personal feedback condition, suggesting that social facilitation rather than loafing underlay the results.

  4. Using multicast in the global communications infrastructure for group communication

    Energy Technology Data Exchange (ETDEWEB)

    Agarwal, Deborah A. [Lawrence Berkeley National Lab. (LBNL), Berkeley, CA (United States)

    1999-07-30

    International Monitoring System (IMS) stations and the International Data Centre (IDC) of the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization generate data and products that must be transmitted to one or more receivers. The application protocols used to transmit the IMS data and IDC products will be CD-x and IMS-x and the World Wide Web (WWW). These protocols use existing Internet applications and Internet protocols to send their data. The primary Internet applications in use are electronic mail (e-mail) and the file transfer protocol (ftp). The primary Internet communication protocol in use is the Transmission Control Protocol (TCP), which provides reliable delivery to the receiver. These Internet applications and protocol provide unicast (point-to-point) communication. A message sent using unicast has a single recipient; any message intended for more than one recipient must be sent to each recipient individually. In the current design, the IDC and the National Data Centres (NDC's) provide data forwarding to the appropriate receivers. The overhead associated with using unicast to transmit messages to multiple receivers either directly or through a forwarder increases linearly with the number of receivers. In addition, using a forwarding site introduces possible delays and possible points of failure in the path to the receivers. Reliable multicast provides communication services similar to TCP but for a group of receivers. The reliable multicast protocol provides group membership services and message delivery ordering. If an IMS station were to send its data using reliable multicast instead of unicast, only sites that are members of the multicast group would receive the data at approximately the same time. This might provide an efficient means of disseminating station data or IDC data products to all receivers and eliminate or greatly reduce the need for data forwarding. Several commercial and research reliable multicast

    The Direct Method and the Communicative Approach are two different kinds of methods in teaching foreign languages. There are obvious advantages in using the Direct Method. However,people found a number of shortcomings in this method. It is not easy to apply after the first stages of language learning when ideas and concepts become more abstract and complicated. This method assumes that adults can learn a second language the same way that children learn their first language. However,more attention should be paid to the differences between these two groups of people.Obviously,the Communicative Approach contributes a lot to the foreign language teaching. But it is certain that it’s not a perfect teaching system. There are quite a few questions needing resolutions.Developing a methodology involves the synthesis of theory and practice into a program that works. It generally means drawing from several methods and approaches in order to create an integrated curriculum that will meet the needs of the situation and students. Integrative and / or instrumental goals,the particular concepts being taught,learning and teaching preferences,cultural factors,and age and competency levels of students are all important considerations.

    Since the 1970s. the Communicative Approach has been introduced into the field of EFL in China. From then on. EFL experts, teacher trainers and textbook compilers have made enormous effort to reform ELT in areas such as teacher training,course development and classroom practice.For a while.Communicative Approach has been regarded as the only best method to language teaching because of its proposals and principles like authentic material, learner-centeredness and taskbased teaching model. However. nowadays, there are still some traditional textbooks used in many colleges and universities.Many of the contents are not authentic and the exercises are not aimed to develop students' competence to use language for communication. Does it mean that we can't adopt the Communicative Approach to deal with the traditional material?Through the author's own experience, it can be concluded that the Communicative Approach is also applicable to the teaching of reading course even with the traditional textbooks.

    Rapid growth in air travel has been projected to continue for the foreseeable future. To maintain a safe and efficient national and global aviation system, significant advances in communications systems supporting aviation are required. Satellites will increasingly play a critical role in the aeronautical communications network. At the same time, current ground-based communications links, primarily very high frequency (VHF), will continue to be employed due to cost advantages and legacy issues. Hence a hybrid satellite-terrestrial network, or group of networks, will emerge. The increased complexity of future aeronautical communications networks dictates that system-level modeling be employed to obtain an optimal system fulfilling a majority of user needs. The NASA Glenn Research Center is investigating the current and potential future state of aeronautical communications, and is developing a simulation and modeling program to research future communications architectures for national and global aeronautical needs. This paper describes the primary requirements, the current infrastructure, and emerging trends of aeronautical communications, including a growing role for satellite communications. The need for a hybrid communications system architecture approach including both satellite and ground-based communications links is explained. Future aeronautical communication network topologies and key issues in simulation and modeling of future aeronautical communications systems are described.

    Full Text Available Cognitive approach (viewpoint/standpoirit in the retrieval and communication of information, as well as in librarianship and information science has started gaining importance in the 70's. Today, it is present in literary and objective knowledge studies, as well as in studies of users,information brokers and systems of information retrieval.Cognitive approach exercises strong impact on several scientific disciplines which are grouped under the roof of cognitive science. The cognitive approach has caused split and the formation of a new paradigm, i.e. the cognitive paradigm, in many scientific disciplines.In the frames of the definition of Kuhn's concept of paradigm, it is evident that librarianship and information science are on the pre-paradigmatic level. I Iowever,some authors mention the existence of at least two paradigms in library and information science, i.e. physical and cognitive paradigm.The hištorical overview of cognitive oriented research works of Brookes, De Mey,Belkin, Ingwersen and others enables the insight into the development of library and information scientific thought up to the present.

    2014-12-01

    Full Text Available As part of a strategic approach, aimed at assuring mutual benefits for the social cause and the business organization, a good CSR - Corporate Social Responsibility communication is vital for the success of a CSR program. We argue that there is not a problem with the legitimacy of the CSR concept, but rather to its implementation. If a business organization implementing socially responsible initiatives is focusing only on reaping the image benefits from a simple public relations perspective, then it loses all the potential business benefits it could gain from a strategic approach focused on long term real results in a win-win perspective. The fact that the image benefit is one of the most important incentives that a business organization could obtain for engaging in CSR activities cannot be ignored, and that is the reason why we have chosen to analyse the topic of CSR communication, mainly external communication, as an important link in the process of implementing a CSR program, that plays an important part for the success of a CSR program. The approach on CSR communication should definitely be a strategic one, and long already common forms of external CSR communication like web pages or CSR annual reports new means of social media networks have an increasing importance. For the practical part of the paper, we were interested in analyzing how much of the external CSR communication in the Romanian business environment is oriented toward a traditional or a strategic approach.

  5. The intergroup protocols: Scalable group communication for the internet

    2000-12-04

    Reliable group ordered delivery of multicast messages in a distributed system is a useful service that simplifies the programming of distributed applications. Such a service helps to maintain the consistency of replicated information and to coordinate the activities of the various processes. With the increasing popularity of the Internet, there is an increasing interest in scaling the protocols that provide this service to the environment of the Internet. The InterGroup protocol suite, described in this dissertation, provides such a service, and is intended for the environment of the Internet with scalability to large numbers of nodes and high latency links. The InterGroup protocols approach the scalability problem from various directions. They redefine the meaning of group membership, allow voluntary membership changes, add a receiver-oriented selection of delivery guarantees that permits heterogeneity of the receiver set, and provide a scalable reliability service. The InterGroup system comprises several components, executing at various sites within the system. Each component provides part of the services necessary to implement a group communication system for the wide-area. The components can be categorized as: (1) control hierarchy, (2) reliable multicast, (3) message distribution and delivery, and (4) process group membership. We have implemented a prototype of the InterGroup protocols in Java, and have tested the system performance in both local-area and wide-area networks.

    The analysis of communicative intents is described as it has developed over time, beginning with J.L. Austin's work published in 1975. Recommendations for best practice are offered in which a situated approach is advocated. Key elements of this approach are a focus on contextual variables and open-ended, rather than list-oriented, assessments of range of intents. It is argued that intents must be assessed relative to the environment, with documentation of environmental variables such as barriers to communicative opportunity. Further, caution is urged in using lists of intents as the sole guide to analysis, because such lists serve to limit awareness of individual differences and multifunctionality of utterances.

    Since the 1970's,as the main course of Chinese middle school,English became important day by day.For many years,traditional teaching method was used in English teaching that is the Grammar Translation Method.It emphasizes the importance of memorizing grammar rules and vocabulary.This viewpoint caused a result:the students call get high marks in examination,but their ability of using language is poor.Although they mastered many grammar rules,remembered a lot of new words,they were unable to communicate with each other by language.This kind of situation must be changed.Therefore,new teaching method Was called for.For more and more people realized that English should be regarded as a kind of communicative tool and be taught as a kind of skill,not just a subject in school.Since the early years of the 1970's,an advanced method-the communicative approach prevailed in the world and later was introducod into our country.However,some teachers still insisted that grammar learning should be paid more attention,because the entrance examination to college still put more emphasis on this.They also thought that communicative approach had nothing to do with the grammar teaching.So the aim of the paper is to illustrate the advantage of the communicative approach by introducing the basic knowledge of this method.

  12. Crisis Communication Competence in Co-Producing Safety with Citizen Groups

    Anne Laajalahti

    2016-03-01

    Full Text Available The aim of this article is to explore interpersonal communication competence needed by crisis communication and management experts when co-operating with citizen groups in response to emergencies. Moreover, the purpose is to understand how response organizations can further develop this crisis communication competence and so contribute to the functioning of response networks. The research task is approached qualitatively by eliciting crisis communication and management experts’ (n = 33 perceptions of the interpersonal communication competence response organizations needs when co-operating with citizen groups. The data were gathered via an international online questionnaire using a method referred to as “thematic writing” and consist of written responses to open-ended questions on what constitutes the core of crisis communication competence and what aspects of it need more attention. The research findings indicate that co-producing safety with citizen groups demands crisis communication competence related to message production, message reception, and interaction between experts and citizen groups. In addition, the findings clarify what areas of crisis communication competence need to be further developed to facilitate co-operation between experts and citizen groups. However, the authors suggest that crisis communication competence should not be seen solely as a characteristic of individual crisis communicators but approached as a networked and co-created area of competence.

  13. An efficient scalable key management scheme for secure group communication

    Institute of Scientific and Technical Information of China (English)

    ZHANG Jun; GU Da-wu; MA Fan-yuan; BAI Ying-cai

    2006-01-01

    Several multicast key management schemes such as those proposed by Wallner et al and Wong et al are based on a multilevel, logical hierarchy (or tree) of key-encrypting keys. When used in conjunction with a reliable multicast infrastructure, this approach results in a highly efficient key update mechanism in which the number of multicast messages transmitted upon a membership update is proportional to the depth of the tree,which is logarithmic to the size of the secure multicast group. But this is based on the hypothesis that the tree is maintained in a balanced manner. This paper proposes a scalable rekeying scheme-link-tree structure for implementing secure group communication. Theoretical calculation and experimentation show that this scheme has better performance than the tree structure and the star structure, and at the same time still keep the link-tree structure balanced.

    We examine a potential relevance of methods of harmonic analysis for the study of quantum entanglement. By changing the mathematical object representing quantum states, we reformulate the separability problem in group-theoretical terms. We also translate the positivity of partial transpose (PPT) criterion and one of the necessary-and-sufficient criteria for pure states to the group-theoretical language. The formal relation of our formalism to local hidden variable models is briefly examined. We also remark on the connection between entanglement and some certain non-commutativity.

    Why animal communication displays are so complex and how they have evolved are active foci of research with a long and rich history. Progress towards an evolutionary analysis of signal complexity, however, has been constrained by a lack of hypotheses to explain similarities and/or differences in signalling systems across taxa. To address this, we advocate incorporating a systems approach into studies of animal communication--an approach that includes comprehensive experimental designs and data collection in combination with the implementation of systems concepts and tools. A systems approach evaluates overall display architecture, including how components interact to alter function, and how function varies in different states of the system. We provide a brief overview of the current state of the field, including a focus on select studies that highlight the dynamic nature of animal signalling. We then introduce core concepts from systems biology (redundancy, degeneracy, pluripotentiality, and modularity) and discuss their relationships with system properties (e.g. robustness, flexibility, evolvability). We translate systems concepts into an animal communication framework and accentuate their utility through a case study. Finally, we demonstrate how consideration of the system-level organization of animal communication poses new practical research questions that will aid our understanding of how and why animal displays are so complex. © 2016 The Author(s).

The paper presents advanced buoy communication technologies based on multiagent interaction and data exchange between several monitoring system nodes. The proposed management of buoy communication is based on a clustering algorithm, which enables the performance of the hydrometeorological information system to be enhanced. The experiment is based on the design and analysis of the inexpensive but reliable Baltic Sea autonomous monitoring network (buoys, which would be able to continuously monitor and collect temperature, waviness, and other required data. The proposed approach of multiagent based buoy communication enables all the data from the costal-based station to be monitored with limited transition speed by setting different tasks for the agent-based buoy system according to the clustering information.

  4. Reinforcing Visual Grouping Cues to Communicate Complex Informational Structure.

    Science.gov (United States)

    Bae, Juhee; Watson, Benjamin

    2014-12-01

    In his book Multimedia Learning [7], Richard Mayer asserts that viewers learn best from imagery that provides them with cues to help them organize new information into the correct knowledge structures. Designers have long been exploiting the Gestalt laws of visual grouping to deliver viewers those cues using visual hierarchy, often communicating structures much more complex than the simple organizations studied in psychological research. Unfortunately, designers are largely practical in their work, and have not paused to build a complex theory of structural communication. If we are to build a tool to help novices create effective and well structured visuals, we need a better understanding of how to create them. Our work takes a first step toward addressing this lack, studying how five of the many grouping cues (proximity, color similarity, common region, connectivity, and alignment) can be effectively combined to communicate structured text and imagery from real world examples. To measure the effectiveness of this structural communication, we applied a digital version of card sorting, a method widely used in anthropology and cognitive science to extract cognitive structures. We then used tree edit distance to measure the difference between perceived and communicated structures. Our most significant findings are: 1) with careful design, complex structure can be communicated clearly; 2) communicating complex structure is best done with multiple reinforcing grouping cues; 3) common region (use of containers such as boxes) is particularly effective at communicating structure; and 4) alignment is a weak structural communicator.

    We study a norm for structured sparsity which leads to sparse linear predictors whose supports are unions of prede ned overlapping groups of variables. We call the obtained formulation latent group Lasso, since it is based on applying the usual group Lasso penalty on a set of latent variables. A detailed analysis of the norm and its properties is presented and we characterize conditions under which the set of groups associated with latent variables are correctly identi ed. We motivate and discuss the delicate choice of weights associated to each group, and illustrate this approach on simulated data and on the problem of breast cancer prognosis from gene expression data.

    Communicative Approach has become the mainstream in English Language Teaching in China. The approach which helps realizes the goal of learning languages is using the new-learned language to communicate with other people in real life. Many linguists and teachers consider Communicative Approach as an effective way to solve the problems existing in the teaching and learning process.

  13. The Finite Heisenberg-Weyl Groups in Radar and Communications

    Full Text Available We investigate the theory of the finite Heisenberg-Weyl group in relation to the development of adaptive radar and to the construction of spreading sequences and error-correcting codes in communications. We contend that this group can form the basis for the representation of the radar environment in terms of operators on the space of waveforms. We also demonstrate, following recent developments in the theory of error-correcting codes, that the finite Heisenberg-Weyl groups provide a unified basis for the construction of useful waveforms/sequences for radar, communications, and the theory of error-correcting codes.

  14. Optimal Grouping and Matching for Network-Coded Cooperative Communications

    Network-coded cooperative communications (NC-CC) is a new advance in wireless networking that exploits network coding (NC) to improve the performance of cooperative communications (CC). However, there remains very limited understanding of this new hybrid technology, particularly at the link layer and above. This paper fills in this gap by studying a network optimization problem that requires joint optimization of session grouping, relay node grouping, and matching of session/relay groups. After showing that this problem is NP-hard, we present a polynomial time heuristic algorithm to this problem. Using simulation results, we show that our algorithm is highly competitive and can produce near-optimal results.

    1989-01-01

    Considering recent operating experience as a group-level input factor, aspects of the communication process between crewmembers (captain and first officer) were explored as a possible mediator to performance. Communication patterns were defined by a speech-act typology adapted for the flight-deck setting and distinguished crews that had previously flown together (FT) from those that had not flown together (NFT). A more open communication channel and greater first officer participation in task-related topics was shown by FT crews, while NFT crews engaged in more nontask discourse.

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

    2016-10-01

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

  1. Data Collection for Mobile Group Consumption: An Asynchronous Distributed Approach.

    Science.gov (United States)

    Zhu, Weiping; Chen, Weiran; Hu, Zhejie; Li, Zuoyou; Liang, Yue; Chen, Jiaojiao

    2016-04-06

    Mobile group consumption refers to consumption by a group of people, such as a couple, a family, colleagues and friends, based on mobile communications. It differs from consumption only involving individuals, because of the complex relations among group members. Existing data collection systems for mobile group consumption are centralized, which has the disadvantages of being a performance bottleneck, having single-point failure and increasing business and security risks. Moreover, these data collection systems are based on a synchronized clock, which is often unrealistic because of hardware constraints, privacy concerns or synchronization cost. In this paper, we propose the first asynchronous distributed approach to collecting data generated by mobile group consumption. We formally built a system model thereof based on asynchronous distributed communication. We then designed a simulation system for the model for which we propose a three-layer solution framework. After that, we describe how to detect the causality relation of two/three gathering events that happened in the system based on the collected data. Various definitions of causality relations based on asynchronous distributed communication are supported. Extensive simulation results show that the proposed approach is effective for data collection relating to mobile group consumption.

    2013-06-01

    The purpose of this study was to assess the forms of communication used by coordinators in socioeducational groups in family health programmes. This qualitative, descriptive and exploratory study was conducted with 25 coordinators of groups in eight basic health units from Belo Horizonte, Brazil. Data collection comprised non-participant observation and semistructured interviews with the coordinators. The theoretical basis for research was Bakhtin's formulations and references on communication and health. The gathered information showed that the body, health and disease triad was communicated in groups through different channels and at different levels of discourse. Our conclusion is that coordinators must adopt an approach that values the expression of participants, not just regarding the physical dimensions of health, but also the life of each participant, and should use various forms of communication to foster dialogical educational actions and means for interaction in groups.

    2016-11-01

    Full Text Available In this paper, a data aggregation gateway framework (DA-GW for constrained application protocol (CoAP group communications is proposed. The DA-GW framework is designed to improve the throughput performance and energy efficiency of group communication to monitor and control multiple sensor devices collectively with a single user terminal. The DA-GW consists of four function blocks—the message analyzer, group manager, message scheduler and data handler—and three informative databases—the client database, resource database and information database. The DA-GW performs group management and group communication through each functional block and stores resources in the informative databases. The DA-GW employs international standard-based data structures and provides the interoperability of heterogeneous devices used in various applications. The DA-GW is implemented using a Java-based open source framework called jCoAP to evaluate the functions and performance of the DA-GW. The experiment results showed that the DA-GW framework revealed better performance than existing group communication methods in terms of throughput and energy consumption.

  5. A Secure Session Key Distribution Scheme for Group Communications

    Institute of Scientific and Technical Information of China (English)

    LIN Ren-hung; JAN Jinn-ke

    2006-01-01

    In a secure group communication system, messages must be encrypted before being transmitted to group members to prevent unauthorized access. In many secure group communication schemes, whenever a member leaves or joins the group, group center (GC) immediately changes the common encryption key and sends the new key to all valid members for forward and backward secrecy. If valid members are not on-line, they will miss the rekeying messages and will not be able to decrypt any ciphertext. Therefore, group members must be able to store the state of the system. In some applications, like global positioning systems (GPS) or pay-per-view systems, it is not reasonable to ask group members to stay on-line all the time and save the changes to the system. A hierarchical binary tree-based key management scheme are proposed for a secure group communication. This scheme reduces the key storage requirement of GC to a constant size and the group members are not required to be on-line constantly (stateless).

    This study of group process was motivated by a high-fidelity flight simulator project in which aircrew performance was found to be better when the crew had recently flown together. Considering recent operating experience as a group-level input factor, aspects of the communication process between crewmembers (Captain and First Officer), were explored as a possible mediator to performance. Communication patterns were defined by a speech act typology adapted for the flightdeck setting and distinguished crews that had previously flown together (FT) from those that had not flown together (NFT). A more open communication channel with respect to information exchange and validation and greater First Officer participation in task-related topics was shown by FT crews while NFT crews engaged in more non-task discourse, a speech mode less structured by roles and probably serving a more interpersonal function. Relationships between the speech categories themselves, representing linguistic, and role-related interdependencies provide guidelines for interpreting the primary findings.

    Atmospheric turbulence causes the receive signal intensity on free space optical (FSO) communication links to vary over time. Scintillation fades can stymie connectivity for milliseconds at a time. To approach the information-theoretic limits of communication in such time-varying channels, it necessary to either code across extremely long blocks of data - thereby inducing unacceptable delays - or to vary the code rate according to the instantaneous channel conditions. We describe the design, hardware implementation, and system performance of an FSO modem that employs low-density parity-check (LDPC) coding in an incremental redundancy (IR) hybrid automatic repeat request (HARQ) protocol. Independent tests performed by the U.S. Government demonstrate that our protocol effectively adapts the LDPC code rate to match the instantaneous channel conditions. For links with fixed throughput, this translates to the longest possible range in the presence of optical scintillation; for links with fixed range, this translates to the highest possible average throughput. By leveraging an LDPC that is amenable to low-complexity, high-throughput implementation in hardware, our modem is able to provide throughputs in excess of 850 Mbps on links with ranges greater than 15 kilometers.

    This report describes the development and preliminary application of an experimental test bed for modeling human behavior in the context of a computer generated environment to analyze the effects of variations in communication modalities, incentives and stressful conditions. In addition to detailing the methodological development of a simulated task environment that provides for electronic monitoring and recording of individual and group behavior, the initial substantive findings from an experimental analysis of distributed interactive communication in simulated space dwelling groups are described. Crews of three members each (male and female) participated in simulated "planetary missions" based upon a synthetic scenario task that required identification, collection, and analysis of geologic specimens with a range of grade values. The results of these preliminary studies showed clearly that cooperative and productive interactions were maintained between individually isolated and distributed individuals communicating and problem-solving effectively in a computer-generated "planetary" environment over extended time intervals without benefit of one another's physical presence. Studies on communication channel constraints confirmed the functional interchangeability between available modalities with the highest degree of interchangeability occurring between Audio and Text modes of communication. The effects of task-related incentives were determined by the conditions under which they were available with Positive Incentives effectively attenuating decrements in performance under stressful time pressure.

    Full Text Available Utilizing observation grid and interview study methologies, this research examines the ways in which students communicate with each other while working in a team during problem solving in mathematics. The study focuses primarily on the language used for communication. Results suggest that participants make assumptions to solve mathematical problems and justify their individual opinions, and cooperate and help each other, rarely asking for their teacher’s help, while using both the ordinary, and the mathematical spoken and written language. The interview indicates that students, although not experienced in undertaking group work, are able to readily identify its benefits and positive aspects.

Describes the methodology and provides an overview of the main findings grouped into themes. A large number of recommendations for change have been made to the hospital concerning systems, procedures, structures, training and inter-professional boundaries. Implementation of some of these recommendations has taken place already. Full evaluation of their impact is yet to be determined.

  2. Enable Secure Group Communication in the Mobile Environment

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    This paper considers the key management issue of secure group communication in a highly mobile networking environment. In such environment, there are frequent joining and leaving of members due to roaming or suspending for a period. In order to preserve forward and backward confidentiality, it is necessary to rekey every time a member joins or leaves. This paper introduces a new state-based group key management framework suitable for highly mobile environment. In this scheme, a member enters "Park" state when it is going to roam or suspend for a period, when it becomes active again, it send a request to the key server to get the current group key and changes its state to "Active" again. No rekeying is needed for a roaming, and reliable delivery of rekeying messages is not required for "Park" members. The scheme can notably reduce the communication overhead and provide an efficient method for error recovery.

    2013-08-01

    Full Text Available Unlike fixed or wired networks, mobile ad-hoc networks pose a number of challenges for peer-to-peer communication due to their dynamic nature. This paper presents a novel framework for vehicleto- vehicle communication controlled and facilitated by a group leader within a group of vehicles. A communication model for a pure ad-hoc network is developed with much concern about the privacy and security of the system, for the ease of effective communication between vehicles with a reduced communication and computational overhead when no fixed infrastructure is present in the roadsides. In the proposed protocol, vehicles within a radio frequency form a group. They elect their leader based on some criteria who is then responsible for generating a group public and private key pair. Each vehicle is equipped with a tamper resistant OBU which is capable of generating public/private keys pairs and also self-certifies the generated keys based on one way hash chaining technique. Any vehicle joins the group communicates the group leader, authenticates itself to obtain the group key. Later, the vehicle uses the group key to send traffic related messages to the group leader who is responsible for batch verifying the authenticity of the message from different sources and one hop broadcast them to reduce the computation overhead on message verification in each vehicle. In addition, our scheme adopts the k-anonymity approach to protect user identity privacy, where an attacker cannot associate a message with the sending vehicle. Extensive analysis and simulations show that the proposed architecture provides an efficient and fully self organized system management for car-to-car communication without the need of any external infrastructure.

The purpose of this project was to combine the teaching of communication skills using SPs with clinical reasoning exercises in a Group Objective Structured Clinical Experience (GOSCE) to study feasibility of the approach, the effect on learners' self-efficacy and attitude toward learning communication skills, and the effect of providing multiple sources of immediate, collaborative feedback. GOSCE sessions were piloted in Pediatrics and Medicine clerkships with students assessing their own performance and receiving formative feedback on communication skills from peers, standardized patients (SPs), and faculty. The sessions were evaluated using a retrospective pre/post-training questionnaire rating changes in self-efficacy and attitudes, and the value of the feedback. Results indicate a positive impact on attitudes toward learning communication skills and self-efficacy regarding communication in the clinical setting. Also, learners considered feedback by peers, SPs, and faculty valuable in each GOSCE. The GOSCE is an efficient and learner-centered method to attend to multiple goals of teaching communication skills, clinical reasoning, self-assessment, and giving feedback in a formative setting. The GOSCE is a low-resource, feasible strategy for experiential learning in communication skills and clinical reasoning. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

  16. The Big Information and Communication Groups in the World

    Directory of Open Access Journals (Sweden)

    José Rebelo

    2010-01-01

    Full Text Available The present article addresses the form major world information and communication groups operate, based on strategies of verticalisation of activities that encompass the distinct media segments – newspapers and magazines, television and radio – and stretch to the new technologies, namely telecommunications and Internet access services. Operating through a vertical system, these groups work as a network system by establishing association or merger agreements, protocols to strengthen their commercial relations, and through interpersonal connections. Their corresponding capitals tend to disperse and their ownership is constantly changing, particularly thanks to the involvement of pension funds, which do not disregard the opportunity of alienating property whenever the profit obtained justifies it.Both directly, thanks to the strength of their own products – “global products” that inundate the world market, and indirectly, through the influence they have on others around them, the leading information and communication groups are a decisive factor in the speeding up of the processes of naturalization, the fixing of stereotypes, and in putting on the agenda the topics that will cross through public space.It is undeniable that the advent and massive spread of the new technologies pose a serious threat to the homogenization and the media standardization carried out by the major groups. However, there are still issues that call for moderation when analyzing this issue. Firstly, the power public authorities still detain, especially in non-democratic countries, to interrupt the circulation of contents. Secondly, the attack launched by the large information and communication groups in order to occupy online space themselves. Thirdly, the excess of information flow and the difficulty associated with the need to select and verify.

    By progression of the disease, motor neurons degenerate in patients with amyotrophic lateral sclerosis (ALS) eventually lose nearly all voluntary muscles in the body. They are awake and aware but cannot move or communicate (locked-in state). Since the function of the brain is preserved, one possible measure to support their communication is to interpret their motor intention by decoding (deciphering) brain signals and present it with external devices. This technology called "brain-machine interface (BMI)" is now close to clinical use in Japan and USA.In our system, we record electrocorticogram (ECoG) obtained with subudural electrodes during their motor imagery, decode it and determine the movement they intended. So far, one patient of ALS with severe paralysis, implanted with this electrodes, successfully operated the PC communication tool only by thinking.

  4. Effectiveness of communication strategies for deaf or hard of hearing workers in group settings.

    2014-01-01

    In group settings, background noise and an obstructed view of the speaker are just a few of the issues that can make workplace communication difficult for an individual who is deaf or hard of hearing. Accommodation strategies such as amplification of the speaker's voice or the use of text-based alternatives exist to address these issues. However, recent studies have shown that there are still unmet needs related to workplace communication in group settings for individuals who are deaf or hard of hearing. Identify the most common strategies used by individuals who are deaf or hard of hearing to improve communication in group settings and gauge the perceived effectiveness of those strategies. An online survey was conducted with individuals who self-identified as deaf or hard of hearing. The survey presented specific communication strategies based on three functional approaches (aural/oral, text, visual). The strategies applied to both receptive and expressive communication in five different meeting types ranging in size and purpose. 161 adults (age 22-90 yrs.) with limited hearing ability completed the survey. Text-based strategies were typically the least frequently used strategies in group settings, yet they ranked high in perceived effectiveness for receptive and expressive communication. Those who used an interpreter demonstrated a strong preference for having a qualified interpreter present in the meeting rather than an interpreter acting remotely. For expressive communication, participants in general preferred to use their own voice or signing abilities and ranked those strategies as highly effective. A more accessible workplace for individuals who are deaf or hard of hearing would incorporate more ubiquitous text-based strategy options. Also, qualified interpreters, when used, should be present in the meeting for maximum effectiveness.

  6. Renormalization group approach to superfluid neutron matter

    Energy Technology Data Exchange (ETDEWEB)

    Hebeler, K.

    2007-06-06

    In the present thesis superfluid many-fermion systems are investigated in the framework of the Renormalization Group (RG). Starting from an experimentally determined two-body interaction this scheme provides a microscopic approach to strongly correlated many-body systems at low temperatures. The fundamental objects under investigation are the two-point and the four-point vertex functions. We show that explicit results for simple separable interactions on BCS-level can be reproduced in the RG framework to high accuracy. Furthermore the RG approach can immediately be applied to general realistic interaction models. In particular, we show how the complexity of the many-body problem can be reduced systematically by combining different RG schemes. Apart from technical convenience the RG framework has conceptual advantage that correlations beyond the BCS level can be incorporated in the flow equations in a systematic way. In this case however the flow equations are no more explicit equations like at BCS level but instead a coupled set of implicit equations. We show on the basis of explicit calculations for the single-channel case the efficacy of an iterative approach to this system. The generalization of this strategy provides a promising strategy for a non-perturbative treatment of the coupled channel problem. By the coupling of the flow equations of the two-point and four-point vertex self-consistency on the one-body level is guaranteed at every cutoff scale. (orig.)

    Animals in groups often exchange calls, in patterns whose temporal structure may be influenced by contextual factors such as physical location and the social network structure of the group. We introduce a model-based analysis for temporal patterns of animal call timing, originally developed for networks of firing neurons. This has advantages over cross-correlation analysis in that it can correctly handle common-cause confounds and provides a generative model of call patterns with explicit parameters for the influences between individuals. It also has advantages over standard Markovian analysis in that it incorporates detailed temporal interactions which affect timing as well as sequencing of calls. Further, a fitted model can be used to generate novel synthetic call sequences. We apply the method to calls recorded from groups of domesticated zebra finch (Taeniopygia guttata) individuals. We find that the communication network in these groups has stable structure that persists from one day to the next, and that 'kernels' reflecting the temporal range of influence have a characteristic structure for a calling individual's effect on itself, its partner and on others in the group. We further find characteristic patterns of influences by call type as well as by individual.

  10. Context-aware adaptation for group communication support applications with dynamic architecture

    CERN Document Server

    Rodriguez, Ismael Bouassida; Chassot, Christophe; Jmaiel, Mohamed

    2008-01-01

    In this paper, we propose a refinement-based adaptation approach for the architecture of distributed group communication support applications. Unlike most of previous works, our approach reaches implementable, context-aware and dynamically adaptable architectures. To model the context, we manage simultaneously four parameters that influence Qos provided by the application. These parameters are: the available bandwidth, the exchanged data communication priority, the energy level and the available memory for processing. These parameters make it possible to refine the choice between the various architectural configurations when passing from a given abstraction level to the lower level which implements it. Our approach allows the importance degree associated with each parameter to be adapted dynamically. To implement adaptation, we switch between the various configurations of the same level, and we modify the state of the entities of a given configuration when necessary. We adopt the direct and mediated Producer-...

  11. A New Scalable and Reliable Cost Effective Key Agreement Protocol for Secure Group Communication

    Directory of Open Access Journals (Sweden)

    S. J. Begum

    2011-01-01

    Full Text Available Problem statement: In a heterogeneous environment, for a secure multicast communication, the group members have to share a secret key which is used to encrypt/decrypt the secret messages among the members. The Secure Group Communication of large scale multicast group in a dynamic environment is more complex than securing one-to-one communication due to the inherent scalability issue of group key management. Since the group members are dynamic in nature such as joining or leaving the group, the key updating is performed among the valid members without interrupting the multicast session so that non group members can’t have access to the future renewed keys. Approach: The main aim is to develop a scheme which can reduce the cost of computational overhead, number of messages needed during the time of key refreshing and the number of keys stored in servers and members. The cost of establishing the key and renewal is proportionate to the size of the group and subsequently fetches a bottleneck performance in achieving scalability. By using a Cluster Based Hierarchical Key Distribution Protocol, the load of key management can be shared among dummy nodes of a cluster without revealing the group messages to them. Results: Especially, the existing model incurs a very less computational and communication overhead during renewal of keys. The proposed scheme yields better scalability because of the fact that the Key computational cost, the keys stored in key server and numbers of rekey-messages needed are very less. Conclusion: Our proposed protocol is based on Elliptic curve cryptography algorithm to form secure group key, even with smaller key size, it is capable of providing more security. This protocol can be used both in wired or wireless environments.

    2017-01-01

    Background Overdiagnosis is considered a risk associated with the diagnosis of osteoporosis–as many people diagnosed won’t experience harm from the condition. As yet there’s little evidence on community understanding of overdiagnosis outside cancer- where it is an established risk of some screening programs–or effective ways to communicate about it. We examined community understanding around overdiagnosis of osteoporosis, to optimise communication strategies about this problem. Methods and findings Using a qualitative design we recruited a community sample of women, 50–80 years, from the Gold Coast community around Bond University, Australia, using random digit dialing, and conducted 5 focus groups with 41 women. A discussion guide and 4-part presentation were developed and piloted, with independent review from a consumer and clinical experts. Initial discussion had 4 segments: osteoporosis; bone density vs. other risk factors; medication; and overdiagnosis. The second half included the 4 short presentations and discussions on each. Analysis used Framework Analysis method. Initially participants described osteoporosis as bone degeneration causing some fear, demonstrated imprecise understanding of overdiagnosis, had a view osteoporosis couldn’t be overdiagnosed as bone scans provided “clear cut” results, expressed belief in early diagnosis, and interest in prevention strategies enabling control. Following presentations, participants expressed some understanding of overdiagnosis, preference for describing osteoporosis as a “risk factor” not “disease”, concern about a poor risk-benefit ratio for medications, and surprise and unease the definition of osteoporosis decided bone density of young women was “normal”, without age adjustment. Limitations include English-speaking backgrounds of the sample and complex materials. Conclusions Our findings suggest a gap between community expectations and how experts sometimes arbitrarily set low

    Full Text Available Approaching the traditional problems of communication in the organizations researched by social science, we have centered our attention in the vertical communication. In this type of communication we found difficulties and barriers for the operation of the organizations, given the presence of latent elements like the social stratification and, very specially, the existing differences of power and status in the organization, in nothing different -in this sense- from other social systems. For such aim, we have selected three cases of companies -in made studies previously- to investigate in the form in which their actors perceive the ascending and descendent communication, as well as the problems that imply in their organizations.

  2. Modular approach for satellite communication ground terminals

    Gould, G. R.

    1984-01-01

    The trend in satellite communications is toward completely digital, time division multiple access (TDMA) systems with uplink and downlink data rates dictated by the type of service offered. Trunking terminals will operate in the 550 MBPS (megabit per second) region uplink and downlink, whereas customer premise service (CPS) terminals will operate in the 25 to 10 MBPS region uplink and in the 200 MBPS region downlink. Additional criteria for the ground terminals will be to maintain clock sychronization with the system and burst time integrity to within a matter of nanoseconds, to process required order-fire information, to provide adaptive data scrambing, and to compensate for variations in the user input output data rates, and for changes in range in the satellite communications links resulting from satellite perturbations in orbit. To achieve the required adaptability of a ground terminal to the above mentioned variables, programmable building blocks can be developed that will meet all of these requirements. To maintain system synchronization, i.e., all bursted data arriving at the satellite within assigned TDMA windows, ground terminal transmit data rates and burst timing must be maintained within tight tolerances. With a programmable synchronizer as the heart of the terminal timing generation, variable data rates and burst timing tolerances are achievable. In essence, the unit inputs microprocessor generated timing words and outputs discrete timing pulses.

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

    Tuci, Elio; Ampatzis, Christos; Vicentini, Federico; Dorigo, Marco

    2008-01-01

    This article describes a simulation model in which artificial evolution is used to design homogeneous control structures and adaptive communication protocols for a group of three autonomous simulated robots. The agents are required to cooperate in order to approach a light source while avoiding collisions. The robots are morphologically different: Two of them are equipped with infrared sensors, one with light sensors. Thus, the two morphologically identical robots should take care of obstacle avoidance; the other one should take care of phototaxis. Since all of the agents can emit and perceive sound, the group's coordination of actions is based on acoustic communication. The results of this study are a proof of concept: They show that dynamic artificial neural networks can be successfully synthesized by artificial evolution to design the neural mechanisms required to underpin the behavioral strategies and adaptive communication capabilities demanded by this task. Postevaluation analyses unveil operational aspects of the best evolved behavior. Our results suggest that the building blocks and the evolutionary machinery detailed in the article should be considered in future research work dealing with the design of homogeneous controllers for groups of heterogeneous cooperating and communicating robots.

  5. How can a multimodal approach to primate communication help us understand the evolution of communication?

    2013-07-18

    Scientists studying the communication of non-human animals are often aiming to better understand the evolution of human communication, including human language. Some scientists take a phylogenetic perspective, where the goal is to trace the evolutionary history of communicative traits, while others take a functional perspective, where the goal is to understand the selection pressures underpinning specific traits. Both perspectives are necessary to fully understand the evolution of communication, but it is important to understand how the two perspectives differ and what they can and cannot tell us. Here, we suggest that integrating phylogenetic and functional questions can be fruitful in better understanding the evolution of communication. We also suggest that adopting a multimodal approach to communication might help to integrate phylogenetic and functional questions, and provide an interesting avenue for research into language evolution.

    The Internet of Things (IoT) is expanding rapidly to new domains in which embedded devices play a key role and gradually outnumber traditionally-connected devices. These devices are often constrained in their resources and are thus unable to run standard Internet protocols. The Constrained Application Protocol (CoAP) is a new alternative standard protocol that implements the same principals as the Hypertext Transfer Protocol (HTTP), but is tailored towards constrained devices. In many IoT application domains, devices need to be addressed in groups in addition to being addressable individually. Two main approaches are currently being proposed in the IoT community for CoAP-based group communication. The main difference between the two approaches lies in the underlying communication type: multicast versus unicast. In this article, we experimentally evaluate those two approaches using two wireless sensor testbeds and under different test conditions. We highlight the pros and cons of each of them and propose combining these approaches in a hybrid solution to better suit certain use case requirements. Additionally, we provide a solution for multicast-based group membership management using CoAP.

    Landulfo, André G. S.

    2016-05-01

    We investigate the transmission of both classical and quantum information between two arbitrary observers in globally hyperbolic spacetimes using a quantum field as a communication channel. The field is supposed to be in some arbitrary quasifree state and no choice of representation of its canonical commutation relations is made. Both sender and receiver possess some localized two-level quantum system with which they can interact with the quantum field to prepare the input and receive the output of the channel, respectively. The interaction between the two-level systems and the quantum field is such that one can trace out the field degrees of freedom exactly and thus obtain the quantum channel in a nonperturbative way. We end the paper determining the unassisted as well as the entanglement-assisted classical and quantum channel capacities.

  15. Simultaneous use of different communication mechanisms leads to spatial sorting and unexpected collective behaviours in animal groups.

    Science.gov (United States)

    Eftimie, Raluca

    2013-11-21

    Communication among individuals forms the basis of social interactions in every animal population. In general, communication is influenced by the physiological and psychological constraints of each individual, and in large aggregations this means differences in the reception and emission of communication signals. However, studies on the formation and movement of animal aggregations usually assume that all individuals communicate with neighbours in the same manner. Here, we take a new approach on animal aggregations and use a nonlocal mathematical model to investigate theoretically the simultaneous use of two communication mechanisms by different members of a population. We show that the use of multiple communication mechanisms can lead to behaviours that are not necessarily predicted by the behaviour of subpopulations that use only one communication mechanism. In particular, we show that while the use of one communication mechanism by the entire population leads to deterministic movement, the use of multiple communication mechanisms can lead in some cases to chaotic movement. Finally, we show that the use of multiple communication mechanisms leads to the sorting of individuals inside aggregations: individuals that are aware of the location and the movement direction of all their neighbours usually position themselves at the centre of the groups, while individuals that are aware of the location and the movement direction of only some neighbours position themselves at the edges of the groups. © 2013 Elsevier Ltd.

    2016-01-01

    There are some differences between the two kinds of foreign language teaching methods .The Audio-lingual Method can help students gain control over grammatical structures as well as develop their oral ability, and the teaching focus is often on forms rather than functions, so students have learned a lot of structures or patterns without knowing how to use them appropriately in real situations. While the aim of the Communicative Approach is to develop student's communicative competence, which includes both the knowledge about the language and the knowledge about how to use the language appropriately in communication situations.

  17. A Communicative Approach to College English Grammar Teaching and Learning

    2016-01-01

    In response to the misconception that Communicative Language Teaching means no teaching of grammar, it is argued that grammar is as important as traffic rules for safe and smooth traffic on the road. To achieve appropriate and effective commu-nication, a communicative approach to college grammar teaching and learning is proposed. Both teachers and learners should change their attitudes toward and conceptions about grammar teaching and learning;additionally, teaching grammar in the com-pany of reading and writing helps learners learn and acquire grammar in meaningful contexts.

  18. A group theoretic approach to quantum information

    CERN Document Server

    Hayashi, Masahito

    2017-01-01

    This textbook is the first one addressing quantum information from the viewpoint of group symmetry. Quantum systems have a group symmetrical structure. This structure enables to handle systematically quantum information processing. However, there is no other textbook focusing on group symmetry for quantum information although there exist many textbooks for group representation. After the mathematical preparation of quantum information, this book discusses quantum entanglement and its quantification by using group symmetry. Group symmetry drastically simplifies the calculation of several entanglement measures although their calculations are usually very difficult to handle. This book treats optimal information processes including quantum state estimation, quantum state cloning, estimation of group action and quantum channel etc. Usually it is very difficult to derive the optimal quantum information processes without asymptotic setting of these topics. However, group symmetry allows to derive these optimal solu...

  19. The communication of "pure" group-based anger reduces tendencies toward intergroup conflict because it increases out-group empathy.

    de Vos, Bart; van Zomeren, Martijn; Gordijn, Ernestine H; Postmes, Tom

    2013-08-01

    The communication of group-based anger in intergroup conflict is often associated with destructive conflict behavior. However, we show that communicating group-based anger toward the out-group can evoke empathy and thus reduce intergroup conflict. This is because it stresses the value of maintaining a positive long-term intergroup relationship, thereby increasing understanding for the situation (in contrast to the communication of the closely related emotion of contempt). Three experiments demonstrate that the communication of group-based anger indeed reduces destructive conflict intentions compared with (a) a control condition (Experiments 1-2), (b) the communication of group-based contempt (Experiment 2), and (c) the communication of a combination of group-based anger and contempt (Experiments 2-3). Moreover, results from all three experiments reveal that empathy mediated the positive effect of communicating "pure" group-based anger. We discuss the implications of these findings for the theory and practice of communicating emotions in intergroup conflicts.

    Grammar is an important part of language learning. In order for students to have a functional knowledge of a language (in other words, that they can spontaneously produce language) they must have at least some knowledge about the grammatical con⁃structs of the language in question. How grammar can be taught? Considering various second language teaching methods, teaching grammar through Communicative Language Teaching Approach is the most talked. Emphasis in this article is put on the applica⁃tion of Communicative Language Teaching Approach in grammar teaching in college English classes.

      With the rapid development of economy and improvement position of English as an international lan-guage in our country,English teaching draw a lot of attention nowadays. In traditional English teaching,it's the teachers who manipulate everything in class,where students are seen as receivers of knowledge. Therefore,it lacks cooperation between teachers and students. Students have no opportunity to apply what they have learnt in class to practical com-munications. In this teachers-centered class,students are not able to bring themselves into ful play,which explains the low quality of English teaching in some schools and students fail to communicate with others after many years' learning. Based on the theory of Communicative Approach,the paper analyses its advantages and existing problems in application and proposes some strategy of improving students'Communicative Competence.

    2005-05-01

    The present report describes the development and application of a distributed interactive multi-person simulation in a computer-generated planetary environment as an experimental test bed for modeling the human performance effects of variations in the types of communication modes available, and in the types of stress and incentive conditions underlying the completion of mission goals. The results demonstrated a high degree of interchangeability between communication modes (audio, text) when one mode was not available. Additionally, the addition of time pressure stress to complete tasks resulted in a reduction in performance effectiveness, and these performance reductions were ameliorated via the introduction of positive incentives contingent upon improved performances. The results obtained confirmed that cooperative and productive psychosocial interactions can be maintained between individually isolated and dispersed members of simulated spaceflight crews communicating and problem-solving effectively over extended time intervals without the benefit of one another's physical presence.

  2. Teamwork and communication: an effective approach to patient safety.

    2014-01-01

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

    2016-08-01

    Full Text Available Based on a brief background of its history, Communicative Language Teaching Approach (CLT will be critically evaluated as theoretical principles as well as its practice in teaching English as a foreign language in the Arab world. The field of language teaching has passed through many changes and shifts over the last few decades. Some suppose that the language instruction has at last come of age (Harper, Lively, and Williams, 1998; others consider it as the post-method area (Richards and Rodgers 2001. In general, it is thought that there is no one particular best method that achieves the goals and meets the needs of all learners and teachers. However, I believe that the flexibility of CLT explains why it can continue and dominate the teaching environments. The term Communicative approach is an umbrella for all teaching methods whose goals are improving students’ abilities to communicate. It embraces all kinds of teaching approaches. Most lessons presentations I have seen so far about Task Based Approach, Humanistic Approach and even Total Physical Response Method are communicative. There was communication between the teacher and the students or among students themselves. The purpose of my writing is to highlight some of the difficulties of the application of this approach in the Arab world especially Egypt although I do believe those points of weakness could be easily overcome by a few modifications and regulations. This article is divided into four main sections; the first is an introduction and a historical background about CLT. The second is the CLT theoretical principles with a critical view. The third is a critical evaluation of the CLT practice especially in the Arab World. Finally, there is a conclusion followed by references.

    2016-01-01

    The traditional ways of teaching in China put emphasis on the development of reading and grammar. So students are fa-mous for their high marks in reading and low marks in listening, and lack of communicative competence. To solve this problem, this study introduces Communicative Approach (CA ) to the English listening class. In order to investigate the effects of the CA on students’listening abilities further, a 18-week comparative study on two classes is conducted. The data show that students’ listening abilities and attitudes in the CA class is significantly higher and more positive than those in the traditional class, which indicates that CA is an effective approach in improving students’listening abilities compared to the traditional approach.

    Two problems are proposed. The first one is the noise decontamination of chaotic carriers using a deterministic approach to reconstruct pseudo trajectories, the second is the design of communications schemes with chaotic carriers. After presenting our deterministic noise decontamination algorithm, conventional chaos shift keying (CSK) communication system is applied. The difference of Euclidean distance between noisy trajectory and decontaminated trajectory in phase space could be utilized to non-coherently detect the sent symbol simply and effectively. It is shown that this detection method can achieve the bit error rate performance comparable to other non-coherent systems.

    Many distributed applications require a secure reliable group communication system to provide coordination among the application components. This paper describes a secure group layer (SGL) which bundles a reliable group communication system, a group authorization and access control mechanism, and a group key agreement protocol to provide a comprehensive and practical secure group communication platform. SGL also encapsulates the standard message security services (i.e, confidentiality, authenticity and integrity). A number of challenging issues encountered in the design of SGL are brought to light and experimental results obtained with a prototype implementation are discussed.

    2014-11-01

    Full Text Available The chiral nucleon-meson model, previously applied to systems with equal number of neutrons and protons, is extended to asymmetric nuclear matter. Fluctuations are included in the framework of the functional renormalization group. The equation of state for pure neutron matter is studied and compared to recent advanced many-body calculations. The chiral condensate in neutron matter is computed as a function of baryon density. It is found that, once fluctuations are incorporated, the chiral restoration transition for pure neutron matter is shifted to high densities, much beyond three times the density of normal nuclear matter.

The aim of an article is to develop methodic approach to diagnostics of internal communications within business-processes management at the industrial enterprise considering all elements in the interior communicational processes. The results of the analysis. Owing the differing character of approaches to estimate internal communications state, study their separate constituents and necessity to form the only approach to diagnose internal communicational processes (ICP at the enterprise, and considering its all constituents, internal communication diagnostics procedure at the enterprise is suggested to conduct by the investigated diagnostics algorithm. According to the algorithm, the object of diagnostics is ICP system with the following components: organizational, informational, technical and technological, social and psychological subsystems. In these four areas the classification of indicators of internal communications effectiveness evaluation was formed. However, having regard to gravity of availability interrelated indicators and a high degree of probability of occurrence duplication settlement we propose narrow down the number of components to two diagnostic groups of indicators: 1 social and organizational (a combination of organizational, social and psychological components. This component is provided for the calculation of such indicators as: coefficient of management reliability, staff loyalty, cohesion in the group, the index productivity growth. 2 technical and informational: the information processing reliability, completeness of the information, software workload coefficient, coefficient of computer using. The received values of the generalized integral factors by the social and organizational and technical and informational components concerning enterprise interior communications are put to the summery table. To estimate enterprise interior communications it is proposed to form matrix of their state

  15. A hierarchical approach to reducing communication in parallel graph algorithms

    KAUST Repository

    Harshvardhan,

    2015-01-01

    Large-scale graph computing has become critical due to the ever-increasing size of data. However, distributed graph computations are limited in their scalability and performance due to the heavy communication inherent in such computations. This is exacerbated in scale-free networks, such as social and web graphs, which contain hub vertices that have large degrees and therefore send a large number of messages over the network. Furthermore, many graph algorithms and computations send the same data to each of the neighbors of a vertex. Our proposed approach recognizes this, and reduces communication performed by the algorithm without change to user-code, through a hierarchical machine model imposed upon the input graph. The hierarchical model takes advantage of locale information of the neighboring vertices to reduce communication, both in message volume and total number of bytes sent. It is also able to better exploit the machine hierarchy to further reduce the communication costs, by aggregating traffic between different levels of the machine hierarchy. Results of an implementation in the STAPL GL shows improved scalability and performance over the traditional level-synchronous approach, with 2.5 × - 8× improvement for a variety of graph algorithms at 12, 000+ cores.

    Our research group of 4 faculty and about 10-15 graduate students was actively involved (as a group) in the development of computer communication networks for the last five years. Many of its individuals have been involved in related research for a much longer period. The overall research goal is to extend network performance to higher data rates, to improve protocol performance at most ISO layers and to improve network operational performance. We briefly state our research goals, then discuss the research accomplishments and direct your attention to attached and/or published papers which cover the following topics: scalable parallel communications; high performance interconnection between high data rate networks; and a simple, effective media access protocol system for integrated, high data rate networks.

  4. Music and health communication in The Gambia: A social capital approach.

    Science.gov (United States)

    McConnell, Bonnie B

    2016-11-01

    Drawing on ethnographic research with kanyeleng fertility society performers and health workers in The Gambia (2012-2013), this paper uses a social capital approach to analyze the relationship between musical performance and health communication. Health communication research has demonstrated the important role of social capital in mediating the impact of interventions. Music research has drawn attention to performance as a site in which social relationships and obligations are produced and negotiated. In this paper, I bring these two perspectives together in order to open up new ways of thinking about musical performance as a culturally appropriate strategy in health communication. Drawing on participant observation as well as individual and group interviews with performers and health workers (126 participants), I argue that kanyeleng performance facilitates health communication by building on existing social networks and forms of social capital. This research contributes to a paradigm shift in research on performance and health communication, moving away from individual-focused behaviour change communication, and toward a culture-centered approach that considers community participation in relation to broader social and structural issues. This research suggests that musical genres such as kanyeleng performance may help build trust between health professionals and target communities while also facilitating information dissemination and public debate on sensitive health topics.

    King, Andrew J; Narraway, Claire; Hodgson, Lindsay; Weatherill, Aidan; Sommer, Volker; Sumner, Seirian

    2011-04-23

    Early hominids searched for dispersed food sources in a patchy, uncertain environment, and modern humans encounter equivalent spatial-temporal coordination problems on a daily basis. A fundamental, but untested assumption is that our evolved capacity for communication is integral to our success in such tasks, allowing information exchange and consensus decisions based on mutual consideration of pooled information. Here we examine whether communication enhances group performance in humans, and test the prediction that consensus decision-making underlies group success. We used bespoke radio-tagging methodology to monitor the incremental performance of communicating and non-communicating human groups (small group sizes of two to seven individuals), during a social foraging experiment. We found that communicating groups (n = 22) foraged more effectively than non-communicating groups (n = 21) and were able to reach consensus decisions (an 'agreement' on the most profitable foraging resource) significantly more often than non-communicating groups. Our data additionally suggest that gesticulations among group members played a vital role in the achievement of consensus decisions, and therefore highlight the importance of non-verbal signalling of intentions and desires for successful human cooperative behaviour.

  9. An annotation based approach to support design communication

    CERN Document Server

    Hisarciklilar, Onur

    2007-01-01

    The aim of this paper is to propose an approach based on the concept of annotation for supporting design communication. In this paper, we describe a co-operative design case study where we analyse some annotation practices, mainly focused on design minutes recorded during project reviews. We point out specific requirements concerning annotation needs. Based on these requirements, we propose an annotation model, inspired from the Speech Act Theory (SAT) to support communication in a 3D digital environment. We define two types of annotations in the engineering design context, locutionary and illocutionary annotations. The annotations we describe in this paper are materialised by a set of digital artefacts, which have a semantic dimension allowing express/record elements of technical justifications, traces of contradictory debates, etc. In this paper, we first clarify the semantic annotation concept, and we define general properties of annotations in the engineering design context, and the role of annotations in...

    2007-12-01

    This study examined 128 working adults' attitudes of tolerance for disagreement, tolerance for ambiguity, and argumentativeness in relation to their dislike for working in a group. They completed the Revised Tolerance for Disagreement Scale, the Multiple Stimulus Types Ambiguity Tolerance Scale, the Argumentativeness Scale, and the Grouphate Scale. Dislike for working in a group correlated negatively with Tolerance for Disagreement (r = -.28, p Tolerance for Ambiguity (r = -.21, p < .05, r2 = .04), and Argumentativeness (r = -.21, p < .05, r2 = .04). Although these correlations are in the expected directions, magnitudes are very weak; unaccounted for variance should be examined.

    Full Text Available Abstract Nurses' perceptions and experiences of communication in the operating theatre: a focus group interview Background Communication programmes are well established in nurse education. The focus of programmes is most often on communicating with patients with less attention paid to inter-professional communication or skills essential for working in specialised settings. Although there are many anecdotal reports of communication within the operating theatre, there are few empirical studies. This paper explores communication behaviours for effective practice in the operating theatre as perceived by nurses and serves as a basis for developing training. Methods A focus group interview was conducted with seven experienced theatre nurses from a large London teaching hospital. The interview explored their perceptions of the key as well as unique features of effective communication skills in the operating theatre. Data was transcribed and thematically analysed until agreement was achieved by the two authors. Results There was largely consensus on the skills deemed necessary for effective practice including listening, clarity of speech and being polite. Significant influences on the nature of communication included conflict in role perception and organisational issues. Nurses were often expected to work outside of their role which either directly or indirectly created barriers for effective communication. Perceptions of a lack of collaborative team effort also influenced communication. Conclusion Although fundamental communication skills were identified for effective practice in the operating theatre, there were significant barriers to their use because of confusion over clarity of roles (especially nurses' roles and the implications for teamwork.

    Stephens, Ashley M.; Huang, Jingjing; Nemoto, Kae; Munro, William J.

    2013-05-01

    We present a layered hybrid-system approach to quantum communication that involves the distribution of a topological cluster state throughout a quantum network. Photon loss and other errors are suppressed by optical multiplexing and entanglement purification. The scheme is scalable to large distances, achieving an end-to-end rate of 1 kHz with around 50 qubits per node. We suggest a potentially suitable implementation of an individual node composed of erbium spins (single atom or ensemble) coupled via flux qubits to a microwave resonator, allowing for deterministic local gates, stable quantum memories, and emission of photons in the telecom regime.

  4. An approach to computing direction relations between separated object groups

    Yan, H.; Wang, Z.; Li, J.

    2013-09-01

    Direction relations between object groups play an important role in qualitative spatial reasoning, spatial computation and spatial recognition. However, none of existing models can be used to compute direction relations between object groups. To fill this gap, an approach to computing direction relations between separated object groups is proposed in this paper, which is theoretically based on gestalt principles and the idea of multi-directions. The approach firstly triangulates the two object groups, and then it constructs the Voronoi diagram between the two groups using the triangular network. After this, the normal of each Voronoi edge is calculated, and the quantitative expression of the direction relations is constructed. Finally, the quantitative direction relations are transformed into qualitative ones. The psychological experiments show that the proposed approach can obtain direction relations both between two single objects and between two object groups, and the results are correct from the point of view of spatial cognition.

    Partners have a burdensome time during and after their partners' intensive care period. They may appear to be coping well outwardly but inside feel vulnerable and lost. Evaluated interventions for partners on this aspect are limited. The aim of this study was to describe the experience of participating in group communication with other partners of former intensive care patients. The study has a descriptive intervention-based design where group communication for partners of former, surviving intensive care unit (ICU) patients was evaluated. A strategic selection was made of adult partners to former adult intensive care patients (n = 15), 5 men and 10 women, aged 37-89 years. Two group communication sessions lasting 2 h were held at monthly intervals with three to five partners. The partners later wrote, in a notebook, about their feelings of participating in group communications. To deepen the understanding of the impact of the sessions, six of the partners were interviewed. Content analysis was used to analyse the notebooks and the interviews. Three categories were identified: (1) Emotional impact, the partners felt togetherness and experienced worries and gratitude, (2) Confirmation, consciousness through insight and reflection and (3) The meeting design, group constellation and recommendation to participate in group communication. Partners of an intensive care patient are on a journey, constantly trying to adapt to the new situation and find new strategies to ever-changing circumstances. Group communications contributed to togetherness and confirmation. To share experiences with others is one way for partners to be able to move forward in life. Group communication with other patients' partners eases the process of going through the burden of being a partner to an intensive care patient. Group communications needs to be further developed and evaluated to obtain consensus and evidence for the best practice. © 2015 British Association of Critical Care Nurses.

    -Message-Receiver Model; and b) only a few interventions in curricula are available for providing the acquisition of interaction skills in supporting autonomy. The proposal of Huber and others to change the emphasis in the definition of the WHO definition on health towards "to adapt and self manage" has impact on the training of medical students and practioners in dealing with patients with low levels of health literacy. From the present study it can be concluded that a dynamic approach to communication can be linked to theoretical constructs on self-management. In such an approach interaction techniques like scaffolding can increase the level of HL of the patient.

    2012-03-01

    To explore and debate nursing leadership and challenges on organizational and group levels when conducting rehabilitation groups for people suffering from chronic pain. Group approaches based on cognitive behavioural therapy are generally described as effective. Leadership in group approaches offered to people suffering from chronic pain is a great challenge for nurses on an organizational as well as a group level. One overall leader and nine group leaders conducting 13 groups constituted the sample. Qualitative content analysis was used by identifying categories, subthemes and themes. The results from the content analysis revealed one main theme ('Complexity in nursing leadership') and three subthemes ('Challenges in leadership on organizational level', 'Challenges in leadership on teamwork level' and 'Challenges in leadership on group level'. The results show how important it is to have firm overall leadership and trained group leaders with a common purpose, interdependent roles and complementary skills, who are thus well prepared to prevent or deal with challenging group processes. The leaders of both levels, which are highly interrelated, should have a current theoretical understanding of pain theory, group leadership skills and a cognitive behavioural approach. © 2012 Blackwell Publishing Ltd.

    To analyze how seasonal communication for dengue control and prevention is conveyed in educational peer groups of Family Health teams. An exploratory and descriptive qualitative study was performed with 25 coordinators of peer education groups, distributed among eight basic health units of Belo Horizonte, Southeastern Brazil. Data collection occurred from March to June 2009, by non-participant observation and semi-structured interviews with coordinators. Content analysis and the principal theories in health communication were utilized in data interpretation. Three thematic units were identified: seasonal communication; subjects discussed and information sources about dengue; and information versus communication for action. Dengue prevention and control actions were principally discussed in groups during outbreaks, based on actions previously programmed by the Ministry of Health. The topics addressed focused on epidemiology, life cycle, modes of transmission, symptoms, prevention, domiciliary visits by zoonosis control units and vaccination for dengue. The predominant communication action is information conveyance by the coordinator, centered on a behavioralist and prescriptive discourse. Communication practices focused on dialogue is recommended, allowing the coordinator and group members freedom in regards to emergent issues in the group, so they learn to recognize and reflexively discuss them in context.

  14. Using Web-Based, Group Communication Systems to Support Case Study Learning at a Distance

    Liam Rourke

    2002-10-01

    Full Text Available This study explored the capacity of Web-based, group communication systems to support case-based teaching and learning. Eleven graduate students studying at a distance were divided into three groups to collaborate on a case study using either a synchronous voice, an asynchronous voice, or a synchronous text communication system. Participants kept a detailed log of the time they spent on various activities, wrote a 1,500-word reflection on their experience, and participated in a group interview. Analysis of these data reveals that each group supplemented the system that had been assigned to them with additional communication systems in order to complete the project. Each of these systems were used strategically: email was used to share files and arrange meetings, and synchronous voice systems were used to brainstorm and make decisions. Learning achievement was high across groups and students enjoyed collaborating with others on a concrete task.

    Kerczewski, Robert J.

    1987-01-01

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

    The satellite communications market is competitive and rapidly evolving. The payload, which is in charge of applying frequency conversion and amplification to the signals received from Earth before their retransmission, is made of various components. These include reconfigurable switches that permit the re-routing of signals based on market demand or because of some hardware failure. In order to meet modern requirements, the size and the complexity of current communication payloads are increasing significantly. Consequently, the optimal payload configuration, which was previously done manually by the engineers with the use of computerized schematics, is now becoming a difficult and time consuming task. Efficient optimization techniques are therefore required to find the optimal set(s) of switch positions to optimize some operational objective(s). In order to tackle this challenging problem for the satellite industry, this work proposes two Integer Linear Programming (ILP) models. The first one is single-objective and focuses on the minimization of the length of the longest channel path, while the second one is bi-objective and additionally aims at minimizing the number of switch changes in the payload switch matrix. Experiments are conducted on a large set of instances of realistic payload sizes using the CPLEX® solver and two well-known exact multi-objective algorithms. Numerical results demonstrate the efficiency and limitations of the ILP approach on this real-world problem.

    Individuals' decisions and behaviour can play a critical role in determining both the probability and severity of injury. Behavioural decision research studies peoples' decision-making processes in terms comparable to scientific models of optimal choices, providing a basis for focusing...... interventions on the most critical opportunities to reduce risks. That research often seeks to identify the ‘mental models’ that underlie individuals' interpretations of their circumstances and the outcomes of possible actions. In the context of injury prevention, a mental models approach would ask why people...... and create an expert model of the risk situation, interviewing lay people to elicit their comparable mental models, and developing and evaluating communication interventions designed to close the gaps between lay people and experts.

    The Unitary Groups Approach (UGA) is an elegant and conceptually unified approach to quantum structure calculations. It has been widely used in molecular structure calculations, and holds the promise of a single computational approach to structure calculations in a variety of different fields. We explore the possibility of extending the UGA to computations in atomic and nuclear structure as a simpler alternative to traditional Racah algebra-based approaches. We provide a simple introduction to the basic UGA and consider some of the issues in using the UGA with spin-dependent, multi-body Hamiltonians requiring multi-shell bases adapted to additional symmetries. While the UGA is perfectly capable of dealing with such problems, it is seen that the complexity rises dramatically, and the UGA is not at this time, a simpler alternative to Racah algebra-based approaches.

    Group therapy is used extensively within public mental health services, but more detailed knowledge is needed. All 25 health authorities in Norway were invited to describe their groups: theory, primary tasks, interventions, structure, patients and therapists. Four hundred twenty-six groups, 296 in community mental health centres and 130 in hospitals, were categorized into nine types, based on theoretical background. Psychodynamic groups were most frequent, followed by cognitive-behavioural, psycho-educative, social skills/coping and art/expressive groups. Weekly sessions of 90 min and treatment duration 12 months was most frequent. Main diagnosis for 2391 patients: depression (517), personality disorder (396), schizophrenia/psychosis (313) and social phobia (249). Patients with depression or personality disorder were mostly in psychodynamic groups, psychosis/bipolar disorder in psycho-educative groups. Cognitive-behavioural groups were used across several diagnoses. Most therapists were nurses, only 50% had a formal training in group therapy. There is a plethora of groups, some based on one theoretical school, while others integrate theory from several 'camps'. Patients with similar diagnosis were offered different group approaches, although some trends existed. More research evidence from regular clinical groups is needed, and clinician-researcher networks should be developed. More group therapists with formal training are needed. © 2013 John Wiley & Sons Ltd.

    2016-01-01

    Full Text Available This paper investigated the couple-group consensus problems of the multiagent networks with the influence of communication and input time delays. Based on the frequency-domain theory, some algebraic criteria are addressed analytically. From the results, it is found that the input time delays and the coupling strengths between agents of the systems play a crucial role in reaching group consensus. The convergence of the system is independent of the communication delays, but it will affect the convergence rate of the system. Finally, several simulated examples are provided to verify the validity and correctness of our theoretical results.

  7. A survey of ring-building network protocols suitable for command and control group communications

    Science.gov (United States)

    Sobeih, Ahmed; Yurcik, William

    2005-05-01

    Multicasting is the enabling technology for group communication. However, network-layer multicasting (e.g., IP multicast) has not been widely adopted more than 10 years of its invention due to the concerns related to deployment, scalability and network management. Application-layer multicast (ALM) has been proposed as an alternative for IP multicast. In ALM, group communications take place on an overlay network in which each edge corresponds to a direct unicast path between two group members. ALM protocols differ in, among other aspects, the topology of the underlying overlay network (e.g., tree, mesh or ring). Ring-based ALM protocols have the advantages of providing a constant node degree, and enabling the implementation of reliable and totally-ordered message delivery through the use of a ring with a token that contains ordering and flow control information. In addition, a ring overlay network topology is inherently reliable to single node failures. In this paper, we provide a survey and a taxonomy of several ring-building group communication protocols. Investigating the major characteristics of ring-building network protocols is an important step towards understanding which of them are suitable for command and control group communications.

  8. Towards scalable quantum communication and computation: Novel approaches and realizations

    Science.gov (United States)

    Jiang, Liang

    Quantum information science involves exploration of fundamental laws of quantum mechanics for information processing tasks. This thesis presents several new approaches towards scalable quantum information processing. First, we consider a hybrid approach to scalable quantum computation, based on an optically connected network of few-qubit quantum registers. Specifically, we develop a novel scheme for scalable quantum computation that is robust against various imperfections. To justify that nitrogen-vacancy (NV) color centers in diamond can be a promising realization of the few-qubit quantum register, we show how to isolate a few proximal nuclear spins from the rest of the environment and use them for the quantum register. We also demonstrate experimentally that the nuclear spin coherence is only weakly perturbed under optical illumination, which allows us to implement quantum logical operations that use the nuclear spins to assist the repetitive-readout of the electronic spin. Using this technique, we demonstrate more than two-fold improvement in signal-to-noise ratio. Apart from direct application to enhance the sensitivity of the NV-based nano-magnetometer, this experiment represents an important step towards the realization of robust quantum information processors using electronic and nuclear spin qubits. We then study realizations of quantum repeaters for long distance quantum communication. Specifically, we develop an efficient scheme for quantum repeaters based on atomic ensembles. We use dynamic programming to optimize various quantum repeater protocols. In addition, we propose a new protocol of quantum repeater with encoding, which efficiently uses local resources (about 100 qubits) to identify and correct errors, to achieve fast one-way quantum communication over long distances. Finally, we explore quantum systems with topological order. Such systems can exhibit remarkable phenomena such as quasiparticles with anyonic statistics and have been proposed as

  9. Theoretical and empirical approaches to using films as a means to increase communication efficiency.

    Directory of Open Access Journals (Sweden)

    Kiselnikova, N.V.

    2016-07-01

    Full Text Available The theoretical framework of this analytic study is based on studies in the field of film perception. Films are considered as a communicative system that is encrypted in an ordered series of shots, and decoding proceeds during perception. The shots are the elements of a cinematic message that must be “read” by viewer. The objective of this work is to analyze the existing theoretical approaches to using films in psychotherapy and education. An original approach to film therapy that is based on teaching clients to use new communicative sets and psychotherapeutic patterns through watching films is presented. The article specifies the main emphasized points in theories of film therapy and education. It considers the specifics of film therapy in the process of increasing the effectiveness of communication. It discusses the advantages and limitations of the proposed method. The contemporary forms of film therapy and the formats of cinema clubs are criticized. The theoretical assumptions and empirical research that could be used as a basis for a method of developing effective communication by means of films are discussed. Our studies demonstrate that the usage of film therapy must include an educational stage for more effective and stable results. This means teaching viewers how to recognize certain psychotherapeutic and communicative patterns in the material of films, to practice the skill of finding as many examples as possible for each pattern and to transfer the acquired schemes of analyzing and recognizing patterns into one’s own life circumstances. The four stages of the film therapeutic process as well as the effects that are achieved at each stage are described in detail. In conclusion, the conditions under which the usage of the film therapy method would be the most effective are observed. Various properties of client groups and psychotherapeutic scenarios for using the method of active film therapy are described.

    Outcomes of a multicomponent psychological intervention designed for the treatment of neuropsychiatric symptoms, communicative and emotional deficits in patients with mild to moderate Alzheimer's dementia were evaluated in a controlled trial. Core components of the program were milieu therapy interventions and music therapy. A total of 49 patients were involved into a pre-post design. The treatment group (n=26) received the program for 6 months, while controls (n=23) participated in standard occupational therapy. Statistical analyses included t-tests, calculation of effect sizes, and two-way analyses of variance. After 6 months, the treatment group showed clear, partly significant improvement of anxiety, agitation, aggression, and apathy as well as social communication, emotional competence and activity levels relative to controls. The program has the potential to increase psychological well-being and to improve communication in patients with Alzheimer's dementia.

    2013-01-01

    Current teaching approaches in human and veterinary medicine across North America, Europe, and Australia include lectures, group discussions, feedback, role-play, and web-based training. Increasing class sizes, changing learning preferences, and economic and logistical challenges are influencing the design and delivery of communication skills in veterinary undergraduate education. The study's objectives were to (1) assess the effectiveness of small-group and web-based methods for teaching communication skills and (2) identify which training method is more effective in helping students to develop communication skills. At the Ross University School of Veterinary Medicine (RUSVM), 96 students were randomly assigned to one of three groups (control, web, or small-group training) in a pre-intervention and post-intervention group design. An Objective Structured Clinical Examination (OSCE) was used to measure communication competence within and across the intervention and control groups. Reliability of the OSCEs was determined by generalizability theory to be 0.65 (pre-intervention OSCE) and 0.70 (post-intervention OSCE). Study results showed that (1) small-group training was the most effective teaching approach in enhancing communication skills and resulted in students scoring significantly higher on the post-intervention OSCE compared to the web-based and control groups, (2) web-based training resulted in significant though considerably smaller improvement in skills than small-group training, and (3) the control group demonstrated the lowest mean difference between the pre-intervention/post-intervention OSCE scores, reinforcing the need to teach communication skills. Furthermore, small-group training had a significant effect in improving skills derived from the initial phase of the consultation and skills related to giving information and planning.

    2012-01-01

    Full Text Available Grouping parts into families which can be produced by a cluster of machine cells is the cornerstone of cellular manufacturing, which in turn is the building block for flexible manufacturing systems. Cellular manufacturing is a group technology (GT concept that has recently attracted the attention of manufacturing firms operating under jobshop environment to consider redesigning their manufacturing systems so as to take advantage of increased throughput, reduction in work-in-progress, set-up time, and lead times; leading to product quality and customer satisfaction. The paper presents a generalised approach for machine cell formation from a jobshop using similarity order clustering technique for preliminary cell grouping and considering machine utilisation for the design of nonintergrouping material handling using the single-pass heuristic. The work addresses the shortcomings of cellular manufacturing systems design and implementations which ignore machine utilisations, group sizes and intergroup moves.

  16. Multiple Methods, Communicative Preferences and the Incremental Interview Approach Protocol

    Directory of Open Access Journals (Sweden)

    David M. Hoffman

    2009-01-01

    Full Text Available This article introduces a multiple methods data collection protocol. The protocol has been designed mainly for those unsure of the practical steps needed to insure coherent data-sets with respect to the substantive, theoretical and methodological issues bearing on their research topic. The protocol is based on experience gained during several qualitative studies and over a decade of discussions with several types of researchers. It is also hoped the protocol provokes discussion amongst experienced researchers. The interplay between purposeful selection and theories of the middle range underpins the rationale for a data collection strategy to be used in qualitative studies where intercultural interaction is obscured by phenomena grounded in two or more cultures. While this protocol will not work with all research topics, it increases data variety and participation regarding many topics, an advantage over survey-based approaches. The protocol highlights the communicative preferences participants have regarding the types of interaction associated with different research methods, especially interviews and data related to interviews. What remains to be done is the development of sound analysis and analytical linkages from qualitative to quantitative research in mixed-methods designs. URN: urn:nbn:de:0114-fqs0901419

    2012-01-01

    Given the increasing demand from wireless applications, designing energy-efficient group communication protocols is of great importance to multi-hop wireless networks. A group communication session involves a set of member nodes, each of them needs to send a certain number of data packets to all other members. In this paper, we consider the problem of building a shared multicast tree spanning the member nodes such that the total energy consumption of a group communication session using the shared multicast tree is minimized. Since this problem was proven as NP-complete, we propose, under our Min-Energy Group COMmunication (MEGCOM) framework, three distributed approximation algorithms with provable approximation ratios. When the transmission power of each wireless node is fixed, our first two algorithms have the approximation ratios of O(ln(\\Delta+ 1)) and O(1), respectively, where \\Delta is the maximum node degree in the network. When the transmission power of each wireless node is adjustable, our third algor...

    Science communication does not have to be a solitary practice. And yet, many scientists go about it alone and with little support from their peers and organizations. To strengthen community and build support for science communicators, NASA designed a training course aimed at two goals: 1) to develop individual scientists' communication skills, and 2) to begin to build a science communication culture at the agency. NASA offered a pilot version of this training course in 2014: the agency's first multidisciplinary face-to-face learning experience for science communicators. Twenty-six Earth, space and life scientists from ten field centers came together for three days of learning. They took part in fundamental skill-building exercises, individual development planning, and high-impact team projects. This presentation will describe the course design and learning objectives, the experience of the participants, and the evaluation results that will inform future offerings of communication training for NASA scientists and others.

  9. Communicative action: the Habermasian and Freirean dialogical approach to participatory communication for social change in a post-1994 South Africa

    Directory of Open Access Journals (Sweden)

    H. Otto

    2009-07-01

    Full Text Available Despite its almost four decade mainstay, the field of parti-cipatory communication for social change still experiences a definitional and pragmatic problem regarding what exactly participation is (cf. Jacobson & Storey, 2004; Chambers, 1994; Melkote & Steeves, 2001; Rogers, 1976; Lerner, 1964; Schramm, 1964; Servaes, 1995. What remains is a vastly under-theorised field of participatory communication for social change. This article examines the possibility of participatory communication approaching the Habermasian “ideal speech situation” in which people, as communicators, are seen as having a value in their own right and not simply regarded as a means to an end (cf. Habermas, 1984; 1987; 1989. Consistent with the Freirean “liberal pedagogy”, the praxis of dialogical communication or intersubjective communication is seen as putting right the “participative” quality of participatory com-munication (cf. Freire, 1970. For both theorists, transformative action can only occur if reflective and collective learning occurs in linguistically constructed settings where the normative dimensions of truth (logos, rightfulness (ethos and truthfulness (pathos are raised and met in the developmental conversation. This is especially significant in a globalised world and fragmented, post-bourgeois public sphere where debate among developmental stakeholders is becoming more marginal, in-strumentalist, and less public. Based on available analyses of development communication literature, this article proposes that the chosen dialogical approaches share a type of communi-cative behaviour (i.e. action theoretic, rather than representing a particular paradigm or school of thought. This could offer further definitional clarification of proper participatory communi-cation for social change in a post-1994 South Africa.

    The difficulty of developing reliable distribution software is an impediment to applying distributed computing technology in many settings. Experience with the ISIS system suggests that a structured approach based on virtually synchronous process groups yields systems that are substantially easier to develop, exploit sophisticated forms of cooperative computation, and achieve high reliability. Six years of research on ISIS, describing the model, its implementation challenges, and the types of applications to which ISIS has been applied are reviewed.

  17. Acoustic environment challenges for the unique communication conditions in group learning classes in elementary school classrooms

    Science.gov (United States)

    Sutherland, Louis; Lubman, David; Pearsons, Karl

    2005-04-01

    Unlike the traditional ``sage-on-the-stage'' configuration of many K-12 classrooms, the group learning or ``guide-on-the-side'' configuration does not involve communication between a teacher in front of a seated class of 20 to 30 students. Instead, it can involve, most of the time, communication between the teacher and each of several small groups of students interacting, aurally, with each other. To maintain the desired 15 dB signal-to-noise ratio intended as the rationale for the ANSI standard, S12.60-2002 on classroom acoustics, the ``noise'' heard by participants in one of the groups is likely to include the speech levels generated by the participants in the other groups as well as the background noise in the unoccupied classroom. Thus, specification of the speech level within (i.e. the ``signal''), and between (i.e. part of the ``noise'') the learning groups, must be considered. Data available to evaluate these speech levels are reviewed and possible models considered to account for the Lombard effect for voice levels of both the teacher and the students. Some of the gaps in these data are suggested as a challenge to stimulate further studies on speech levels of teachers and students in a wide range of communication conditions.

  18. Narratives of empowerment and compliance: studies of communication in online patient support groups.

    Science.gov (United States)

    Wentzer, Helle S; Bygholm, Ann

    2013-12-01

    New technologies enable new forms of patient participation in health care. The article discusses whether communication in online patient support groups is a source of individual as well as collective empowerment or to be understood within the tradition of compliance. The discussion is based on a qualitative analysis of patient communication in two online groups on the Danish portal sundhed.dk, one for lung patients and one for women with fertility problems. The object of study is the total sum of postings during a specific period of time - a total of 4301 posts are included. The textmaterial was analyzed according to the textual paradigm of Paul Ricoeur, and the three steps of critical interpretation. Thus, the analysis moves from describing communicative characteristics of the site to a thorough semantic analysis of its narrative structure of construing meaning, interaction and collective identity, and finally as a source of collective action. The meta-narratives of the two groups confirm online patient support groups for individual empowerment, for collective group identity, but not for collective empowerment. The collective identities of patienthood on the two sites are created by the users (patients) through specific styles of communication and interaction, referred to as 'multi-logical narratives'. In spite of the potential of online communities of opening up health care to the critical voice of the public, the analysis points to a synthesis of the otherwise opposite positions of empowerment and compliance in patient care. On a collective level, the site is empowering the individual users to comply with 'doctor's recommendations' as a group. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

  19. TMDL implementation in agricultural landscapes: a communicative and systemic approach.

    2011-07-01

    Increasingly, total maximum daily load (TMDL) limits are being defined for agricultural watersheds. Reductions in non-point source pollution are often needed to meet TMDL limits, and improvements in management of annual crops appear insufficient to achieve the necessary reductions. Increased adoption of perennial crops and other changes in agricultural land use also appear necessary, but face major barriers. We outline a novel strategy that aims to create new economic opportunities for land-owners and other stakeholders and thereby to attract their voluntary participation in land-use change needed to meet TMDLs. Our strategy has two key elements. First, focused efforts are needed to create new economic enterprises that capitalize on the productive potential of multifunctional agriculture (MFA). MFA seeks to produce a wide range of goods and ecosystem services by well-designed deployment of annual and perennial crops across agricultural landscapes and watersheds; new revenue from MFA may substantially finance land-use change needed to meet TMDLs. Second, efforts to capitalize on MFA should use a novel methodology, the Communicative/Systemic Approach (C/SA). C/SA uses an integrative GIS-based spatial modeling framework for systematically assessing tradeoffs and synergies in design and evaluation of multifunctional agricultural landscapes, closely linked to deliberation and design processes by which multiple stakeholders can collaboratively create appropriate and acceptable MFA landscape designs. We anticipate that application of C/SA will strongly accelerate TMDL implementation, by aligning the interests of multiple stakeholders whose active support is needed to change agricultural land use and thereby meet TMDL goals.

  20. Information Overload in Group Communication: From Conversation to Cacophony in the Twitch Chat

    CERN Document Server

    2016-01-01

    Online communication channels, especially social web platforms, are rapidly replacing traditional ones. Online platforms allow users to overcome physical barriers, enabling worldwide participation. However, the power of online communication bears an important negative consequence --- we are exposed to too much information to process. Too many participants, for example, can turn online public spaces into noisy, overcrowded fora where no meaningful conversation can be held. Here we analyze a large dataset of public chat logs from Twitch, a popular video streaming platform, in order to examine how information overload affects online group communication. We measure structural and textual features of conversations such as user output, interaction, and information content per message across a wide range of information loads. Our analysis reveals the existence of a transition from a conversational state to a cacophony --- a state of overload with lower user participation, more copy-pasted messages, and less informat...

  2. Hierarchical Group Based Mutual Authentication and Key Agreement for Machine Type Communication in LTE and Future 5G Networks

    Directory of Open Access Journals (Sweden)

    Probidita Roychoudhury

    2017-01-01

    Full Text Available In view of the exponential growth in the volume of wireless data communication among heterogeneous devices ranging from smart phones to tiny sensors across a wide range of applications, 3GPP LTE-A has standardized Machine Type Communication (MTC which allows communication between entities without any human intervention. The future 5G cellular networks also envisage massive deployment of MTC Devices (MTCDs which will increase the total number of connected devices hundredfold. This poses a huge challenge to the traditional cellular system processes, especially the traditional Mutual Authentication and Key Agreement (AKA mechanism currently used in LTE systems, as the signaling load caused by the increasingly large number of devices may have an adverse effect on the regular Human to Human (H2H traffic. A solution in the literature has been the use of group based architecture which, while addressing the authentication traffic, has their share of issues. This paper introduces Hierarchical Group based Mutual Authentication and Key Agreement (HGMAKA protocol to address those issues and also enables the small cell heterogeneous architecture in line with 5G networks to support MTC services. The aggregate Message Authentication Code based approach has been shown to be lightweight and significantly efficient in terms of resource usage compared to the existing protocols, while being robust to authentication message failures, and scalable to heterogeneous network architectures.

  3. Effects of longitudinal small-group learning on delivery and receipt of communication skills feedback.

    2013-11-01

    Although feedback is a critical component of learning, recent data suggest that learners may discount feedback they receive. The emotional threat inherent in feedback can contribute to its ineffectiveness, particularly for sensitive topics like communication skills. Longitudinal relationships among peers may increase their sense of safety and soften the perceived threat of feedback to allow students to give, receive and potentially more effectively incorporate feedback. We studied the effects of prior shared learning experiences among medical students in the delivery and receipt of feedback on clinical (communication) skills. During a formative clinical skills examination, we divided Year 3 students at a US medical school into two subgroups comprising, respectively, small-group classmates from a 2-year longitudinal pre-clerkship clinical skills course (with prior peer-learning relationships), and peers with no prior shared small-group coursework. Students in both subgroups observed peers in a simulated clinical case and then provided feedback, which was videotaped, transcribed and coded. Feedback recipients also completed a survey on their perceptions of the feedback. Students valued the feedback they received and intended to enact it, regardless of whether they had prior peer-learning relationships. Coding of feedback revealed high specificity. Feedback providers who had prior peer-learning relationships with recipients provided more specific corrective feedback on communication skills than those with no such relationships (p = 0.014); there was no significant difference between subgroups in the provision of reinforcing feedback on communication skills. Year 3 medical student peers can deliver specific feedback on clinical skills; prior peer-learning relationships in pre-clerkship clinical skills courses enrich the provision of specific corrective feedback about communication skills. Feedback between peers with pre-existing peer-learning relationships represents

  5. Promoting communication, participation, and learning with regard to organic food products: a communication theoretical approach

    Directory of Open Access Journals (Sweden)

    Peter Kastberg

    2015-03-01

    Full Text Available The market for organic foods is growing, however, the proportion of consumers buying organic foods is still considered low. Research shows that a significant barrier to consumers purchasing more organic foods is lack of information. This leads the relevant body of research to call for better communication around organic foods. The same body of research, however, neither questions what good communication surrounding organic foods is, nor what would make it better. Applying the communication theoretical formats of transmission, interaction, and coaction, respectively, onto instances of organic communication activities, I will discuss to what extent each format encourages consumer participation and learning. Transmission, typically in the form of monologuous mass communication, is cost effective. It is also a format that bars a sender, e.g., producer or farmer, from gauging deposits in the consumer, e.g., understanding the message, trusting the sender, etc. Interaction, typically in the form of dialoguous encounters, integrates feedback into communication allowing the sender to appreciate the level of understanding, trust, etc., which the communicative effort has given rise to, albeit at a higher price in terms of money, time, and manpower. In the format of coaction, typically in the form of co-operative endeavors, the deposit is a matter of what is coconstructed by the participants, e.g., understanding, trust, etc. Coaction thus satisfies the organic communicators craving for involving the consumer, and because food is a low-involvement commodity, this is critical. But emancipating the consumer comes at a price. First of all, coactional communication is dependent on highly motivated participants, and second, coactional communication is difficult if not impossible to control. Informed by these insights, I present an in-depth, critical discussion of the promises and pitfalls of how multicriteria assessments may be communicated and coconstructed on a

  6. Novel approaches to mitigating bacterial biofilm formation and intercellular communication

    Science.gov (United States)

    Kasper, Stephen H.

    Long thought of as solitary single-cell organisms, it is now widely accepted that bacteria can act and cooperate as social organisms. Phenomena such as biofilm formation and quorum sensing (QS) are two intimately intertwined cooperative behaviors that significantly contribute to the pathogenesis of many bacteria. Biofilms are surface associated communities of bacteria encased in a secreted extracellular matrix, which provides several advantages over an individualized lifestyle, such as increased protection from antimicrobial agents as well as enhanced opportunity for the exchange of genetic material. Bacterial QS is a system of population-based communication through the production, sensing, and response to chemical signals, often controlling the expression of diverse virulence factors (e.g. toxins, proteases). Biofilm formation and QS are cooperative processes that are often leveraged as bacteria coordinate infection processes, and can therefore be novel targets for anti-infective treatments that differ from conventional antibiotic treatment. Our lab has previously identified a novel class of small molecules that inhibit biofilm formation and disrupt QS by the pathogenic bacterium Pseudomonas aeruginosa. These organosulfur-based compounds are either natural products or related derivatives of the tropical plant Petiveria alliacea. Because oral biofilm (e.g. dental plaque) is a major conduit of oral and systemic disease, and is also a site for horizontal transfer for genes encoding antibiotic resistance, there exists a need for novel strategies for inhibiting oral biofilm development. Therefore, a small library (˜50 compounds) of structural derivatives was developed and screened for their ability to inhibit biofilm formation by multiple orally associated bacteria. The screening effort uncovered several related compounds that inhibited oral biofilm development. To determine how natural product-based organosulfur compounds could be inducing QS inhibitory effects, an

    Full Text Available Abstract Background Guidelines in paediatric oncology encourage health care providers to share relevant information with young patients and parents to enable their active participation in decision making. It is not clear to what extent this mirrors patients' and parents' preferences. This study investigated communication preferences of childhood cancer patients, parents, and survivors of childhood cancer. Methods Communication preferences were examined by means of online focus groups. Seven patients (aged 8–17, 11 parents, and 18 survivors (aged 8–17 at diagnosis participated. Recruitment took place by consecutive inclusion in two Dutch university oncological wards. Questions concerned preferences regarding interpersonal relationships, information exchange and participation in decision making. Results Participants expressed detailed and multi-faceted views regarding their needs and preferences in communication in paediatric oncology. They agreed on the importance of several interpersonal and informational aspects of communication, such as honesty, support, and the need to be fully informed. Participants generally preferred a collaborative role in medical decision making. Differences in views were found regarding the desirability of the patient's presence during consultations. Patients differed in their satisfaction with their parents' role as managers of the communication. Conclusion Young patients' preferences mainly concur with current guidelines of providing them with medical information and enabling their participation in medical decision making. Still, some variation in preferences was found, which faces health care providers with the task of balancing between the sometimes conflicting preferences of young cancer patients and their parents.

    2011-04-01

    This study aims to understand how the risks of snowmobiling are communicated among northern Norwegian youths. Study design. A qualitative design with focus group interviews was chosen. Interviews centred on safety precautions and estimation of risks related to snowmobiling and driving patterns. Eighty-one students (31 girls and 50 boys) aged between 16 and 23 years from 8 high schools were interviewed in 17 focus groups that were segregated by gender. Interview data were analysed using qualitative content analysis. Boys and girls communicated differently about risks. Peer-group conformity appeared stronger among boys than girls. Boys did not spontaneously relate risks to their snowmobile activities, while girls did. Boys focused upon training, coping and balance between control and lack of control while driving. Girls talked about risks, were aware of risks and sought to avoid risky situations, in contrast to boys. Boys' risk communication in groups was about how to manage challenging situations. Their focus overall was on trying to maintain control while simultaneously testing their limits. Three risk categories emerged: those who drive as they ought to (mostly girls), those who occasionally take some risks (boys and girls) and those who are extreme risk-takers (a smaller number of boys). Perceptions of and communication about risk are related to gender, peer group and familiarity with risk-taking when snowmobiling. Northern Norwegian boys' driving behaviour highlights a specific need for risk reduction, but this must also draw upon factors such as acceptance of social and cultural codes and common sense related to snowmobiling.

Existing solutions have several limitations in terms of reliability, flexibility and manageability of such groups of objects. To overcome these limitations we propose an intermediately level of intelligence to easily manipulate a group of resources across multiple smart objects, building upon the Constrained Application Protocol (CoAP). We describe the design of our solution to create and manipulate a group of CoAP resources using a single client request. Furthermore we introduce the concept of profiles for the created groups. The use of profiles allows the client to specify in more detail how the group should behave. We have implemented our solution and demonstrate that it covers the complete group life-cycle, i.e., creation, validation, flexible usage and deletion. Finally, we quantitatively analyze the performance of our solution and compare it against multicast-based CoAP group communication. The results show that our solution improves reliability and flexibility with a trade-off in increased communication overhead.

  16. The Need for More Scientific Approaches to Science Communication

    Sadri, S.

    2015-12-01

    Two possible goals for public science communication are: a) improving the public's in-depth understanding of the scientific subject; and b) fostering the public's belief that scientific efforts make a better world. Although (a) is often a natural target when scientists try to communicate their subject, the importance of (b) is underscored by the NSF, who investigated the "cultural authority of science" to understand science's role in policymaking. Surveys consistently find that there is a huge divergence between "knowledge" and "admiration" of science in society because science literacy has very little to do with public perception of science. However, even if both goals could be achieved, it doesn't necessarily mean that the general public will act on scientific advice. Different parts of society have different criteria for reaching judgments about how to act in their best interests. This makes the study of science communication important when controversies arise requiring public engagement. Climate change, sustainability, and water crises are only a few examples of such controversial subjects. Science communication can be designed carefully to sponsor dialogue and participation, to overcome perceptual obstacles, and to engage with stakeholders and the wider public. This study reviews work in social science that tries to answer: When is science communication necessary? What is involved in science communication? What is the role of media in effective science communication? It also reviews common recommendations for improved public engagement by scientists and science organizations. As part of this effort, I will present some portions of my science films. I will conclude with suggestions on what scientific institutions can focus on to build trust, relationships, and participation across segments of the public. Keywords: informal learning, popular science, climate change, water crisis, science communication, science films, science policy.

    Dog-human communication has been widely investigated recently for different theoretical reasons, in most cases through dogs' comprehension of human gestural cues. Dogs have been reported to be very skilful in comprehending a variety of human pointing gestures in many independent studies. This paper provides a short overview of the possible explanations behind the dogs' exceptional communicational abilities towards humans from an evolutionary perspective, concluding that the different and seemingly contradictory hypotheses are not exclusive but they might have a synergic effect.

  18. Real-space renormalization group approach to the Anderson model

    Science.gov (United States)

    Campbell, Eamonn

    Many of the most interesting electronic behaviours currently being studied are associated with strong correlations. In addition, many of these materials are disordered either intrinsically or due to doping. Solving interacting systems exactly is extremely computationally expensive, and approximate techniques developed for strongly correlated systems are not easily adapted to include disorder. As a non-interacting disordered model, it makes sense to consider the Anderson model as a first step in developing an approximate method of solution to the interacting and disordered Anderson-Hubbard model. Our renormalization group (RG) approach is modeled on that proposed by Johri and Bhatt [23]. We found an error in their work which we have corrected in our procedure. After testing the execution of the RG, we benchmarked the density of states and inverse participation ratio results against exact diagonalization. Our approach is significantly faster than exact diagonalization and is most accurate in the limit of strong disorder.

    The MFA approach for simulations with dynamical fermions in lattice gauge theories allows in principle to explore the parameters space of the theory (e.g. the \\beta, m plane for the study of chiral condensate in QED) without the need of computing the fermionic determinant at each point. We exploit this possibility for extracting both the renormalization group trajectories ("constant physics lines") and the scaling function, and we test it in the Schwinger Model. We discuss the applicability of this method to realistic theories.

    We propose a position-space renormalization group approach for the excluded volume problem in a square lattice by considering “percolating” self-avoiding paths in a b×b cell, where b=2,3,4: Two ways of counting the paths are presented. The values obtained for the exponent v converge respectively to 0.731 and 0.720, close to the usually accepted value v=0.75. Comments on the relation between percolation and self-avoiding walks are made.

    1977-09-01

    A contraction of the Poincare group is performed leading to the eikonal approximation. Invariants, one-particle states, spinning particles and some interaction problems are studied with the following results: momenta of ultrarelativistic particles behave as lightlike, the little group being E/sub 2/, spin behaves as that of zero-mass particles, helicity being conserved in the presence of interactions. The full eikonal results are rederived for Green's functions, wave functions, etc. The way for computing corrections due to transverse momenta and spin-dependent interactions is outlined. A parallel analysis is made for the infinite-momentum frame, the similarities and differences between this formalism and the eikonal approach being disclosed.

    2016-01-01

    We consider the quantum loop effects in scalar electrodynamics on de Sitter space by making use of the functional renormalization group approach. We first integrate out the photon field, which can be done exactly to leading (zeroth) order in the gradients of the scalar field, thereby making this method suitable for investigating the dynamics of the infrared sector of the theory. Assuming that the scalar remains light we then apply the functional renormalization group methods to the resulting effective scalar theory and focus on investigating the effective potential, which is the leading order contribution in the gradient expansion of the effective action. We find symmetry restoration at a critical renormalization scale $\\kappa=\\kappa_{\\rm cr}$ much below the Hubble scale $H$.

    Combination of overlapping pulse position modulation and pulse width modulation at the transmitter and grouped bit-flipping algorithm for low-density parity-check decoding at the receiver are proposed for visible Light Emitting Diode (LED) indoor communication system in this paper. The results demonstrate that, with the same Photodetector, the bit rate can be increased and the performance of the communication system can be improved by the scheme we proposed. Compared with the standard bit-flipping algorithm, the grouped bit-flipping algorithm can achieve more than 2.0 dB coding gain at bit error rate of 10-5. By optimizing the encoding of overlapping pulse position modulation and pulse width modulation symbol, the performance can be further improved. It is reasonably expected that the bit rate can be upgraded to 400 Mbit/s with a single available LED, thus transmission rate beyond 1 Gbit/s is foreseen by RGB LEDs.

    2013-10-01

    Full Text Available In recent years, a number of studies have been conducted with regard to communication strategy training and performance on communicative tasks (Lam, 2009; Nakatani, 2010; Naughton, 2006. This study aims to add to the literature by examining how two strategies, clarifying/confirming and extending a conversation, and two methods of teaching the strategies, affected the interactional sequences and overall group discussion performance of EFL students at a university in Japan. Pre and posttreatment small-group discussions were recorded for assessment, and a stimulated recall interview was administered to determine the participants’ perceptions of their learning and language use. Posttest results reveal that the experimental groups that were taught predetermined phrases aimed at clarifying/confirming and extending a conversation employed such phrases more frequently than the control group. However, this employment of phrases did not lead to higher gains in group discussion skills as the control group enjoyed the largest gains from pre to posttest. The researchers consider the findings in light of previous research, and conclude with recommendations for future research on the topic with special regard to research design.

  6. A Genetic Algorithms Based Approach for Group Multicast Routing

    Luca Sanna Randaccio

    2006-08-01

    Full Text Available Whereas multicast transmission in one-to-many communications allows the operator to drastically save network resources, it also makes the routing of the traffic flows more complex then in unicast transmissions. A huge amount of possible trees have to be considered and analyzed to find the appropriate routing paths. To address this problem, we propose the use of the genetic algorithms (GA, which considerably reduce the number of solutions to be evaluated. A heuristic procedure is first used to discern a set of possible trees for each multicast session in isolation. Then, the GA are applied to find the appropriate combination of the trees to comply with the bandwidth needs of the group of multicast sessions simultaneously. The goodness of each solution is assessed by means of an expression that weights both network bandwidth allocation and one-way delay. The resulting cost function is guided by few parameters that can be easily tuned during traffic engineering operations; an appropriate setting of these parameters allows the operator to configure the desired balance between network resource utilization and provided quality of service. Simulations have been performed to compare the proposed algorithm with alternative solutions in terms of bandwidth utilization and transmission delay.

    2014-01-01

    Public health approaches to communication disability challenge the profession of speech-language pathology (SLP) to reconsider both frames of reference for practice and models of education. This paper reviews the impetus for public health approaches to communication disability and considers how public health is, and could be, incorporated into SLP education, both now and in the future. The paper describes tensions between clinical services, which have become increasingly specialized, and public health approaches that offer a broader view of communication disability and communication disability prevention. It presents a discussion of these tensions and asserts that public health approaches to communication are themselves a specialist field, requiring specific knowledge and skills. The authors suggest the use of the term 'communication disability public health' to refer to this type of work and offer a preliminary definition in order to advance discussion. Examples from three countries are provided of how some SLP degree programmes are integrating public health into the SLP curriculum. Alternative models of training for communication disability public health that may be relevant in the future in different contexts and countries are presented, prompting the SLP profession to consider whether communication disability public health is a field of practice for speech-language pathologists or whether it has broader workforce implications. The paper concludes with some suggestions for the future which may advance thinking, research and practice in communication disability public health. © 2015 S. Karger AG, Basel.

  8. A Human-Centric Approach To Group-Based Context-Awareness

    2011-01-01

    Full Text Available The emerging need for qualitative approaches in context-aware information processing calls for proper modelling of context information and efficient handling of its inherent uncertainty resulted from human interpretation and usage. Many of the current approaches to context-awareness either lack a solid theoretical basis for modelling or ignore important requirements such as modularity, high-order uncertainty management and group-based context-awareness. Therefore, their real-world application and extendibility remains limited. In this paper, we present f-Context as a service-based contextawareness framework, based on language-action perspective (LAP theory for modelling. Then we identify some of the complex, informational parts of context which contain high-order uncertainties due to differences between members of the group in defining them. An agent-based perceptual computer architecture is proposed for implementing f-Context that uses computing with words (CWW for handling uncertainty. The feasibility of f-Context is analyzed using a realistic scenario involving a group of mobile users. We believe that the proposed approach can open the door to future research on context-awareness by offering a theoretical foundation based on human communication, and a service-based layered architecture which exploits CWW for context-aware, group-based and platform-independent access to information systems.

    Full Text Available Background and the goal of the study: The major communicative problems, after marriage, include weakening the couples' communication, unrealistic beliefs, prejudgments and negative attitudes. The aim of this study was to determine the efficacy of Rational- Emotive Behavior Therapy,through group training, on communication beliefs of the couples who referred to counseling centers in Isfahan. Methods: The proposal of the study is a quasi-experimental research design with a pretest – posttest which includes a control group. The study samples encompass all the couples referred to counseling centers in Isfahan. In order to select a sample size, out of the applicants, through voluntary and available sampling method, 30 individuals were selected and randomly assigned to experimental and control groups. The elicitation tool used in this study was Relationship Beliefs Questionnaire. The experimental group was trained by a Rational- Emotive Behavior therapeutic approach and the control group did not receive any training at all. Then for all the participants a post-test was taken and finally after 2 months a follow-up test was conducted. In order to analyze the data, variance with repeated measures and Bonferroni correctionviausing SPSS 20 statistical software were used. Results: The results showed that the group training ofRational- Emotive Behavior therapeutic approach has impact on communicative beliefs and accordingly, there is a significant difference between the communicative beliefs of experimental and control groups(P < 0.01. Discussion: Based on the findings of this study,Rational- Emotive Behavior Therapy can be used to improve the couples' communicative beliefs.

    Full Text Available Nursing education is a process that based on theoretical and practical teaching-learning experiences. In this process, it is proposed that professional knowledge is given to students and reflected to their behoviours, help to develop themself, provide to communicate effectively with healthy/ill person, family and society, other professional members and friends. Communication between faculty and students in the teaching-learning process is vitally important to be able to learn desired behaviors. Because the communication process will affect both the individuals' behaviors as well as their learning, healthy communication needs to be established and maintained, particularly in educational environments. Education today, particularly professional and university level education is defined as an interactive process. Failure to have reciprocal relationships in this interactive process will have a negative effect on education . Based on this information the evaluation of the teacher-learner relationship will be evaluated from a different aspect, the individual and communication theory which is the Transactional Analysis.

  12. Locally Compact Quantum Groups. A von Neumann Algebra Approach

    Science.gov (United States)

    Van Daele, Alfons

    2014-08-01

    In this paper, we give an alternative approach to the theory of locally compact quantum groups, as developed by Kustermans and Vaes. We start with a von Neumann algebra and a comultiplication on this von Neumann algebra. We assume that there exist faithful left and right Haar weights. Then we develop the theory within this von Neumann algebra setting. In [Math. Scand. 92 (2003), 68-92] locally compact quantum groups are also studied in the von Neumann algebraic context. This approach is independent of the original C^*-algebraic approach in the sense that the earlier results are not used. However, this paper is not really independent because for many proofs, the reader is referred to the original paper where the C^*-version is developed. In this paper, we give a completely self-contained approach. Moreover, at various points, we do things differently. We have a different treatment of the antipode. It is similar to the original treatment in [Ann. Sci. & #201;cole Norm. Sup. (4) 33 (2000), 837-934]. But together with the fact that we work in the von Neumann algebra framework, it allows us to use an idea from [Rev. Roumaine Math. Pures Appl. 21 (1976), 1411-1449] to obtain the uniqueness of the Haar weights in an early stage. We take advantage of this fact when deriving the other main results in the theory. We also give a slightly different approach to duality. Finally, we collect, in a systematic way, several important formulas. In an appendix, we indicate very briefly how the C^*-approach and the von Neumann algebra approach eventually yield the same objects. The passage from the von Neumann algebra setting to the C^*-algebra setting is more or less standard. For the other direction, we use a new method. It is based on the observation that the Haar weights on the C^*-algebra extend to weights on the double dual with central support and that all these supports are the same. Of course, we get the von Neumann algebra by cutting down the double dual with this unique

    Appropriate software tools may improve communication and ease access to knowledge for research groups. A weblog is a website which contains periodic, chronologically ordered posts on a common webpage, whereas a wiki is hypertext-based collaborative software that enables documents to be authored collectively using a web browser. Although not primarily intended for use as an intranet-based collaborative knowledge warehouse, both blogs and wikis have the potential to offer all the features of complex and expensive IT solutions. These tools enable the team members to share knowledge simply and quickly-the collective knowledge base of the group can be efficiently managed and navigated.

    2013-03-15

    Modern marketing puts the consumer and not the manufacturer in the center, the essence of the marketing approach being the conception, the projection and the making of the product, starting from the consumer towards the manufacturer; this resulting in the fact that the product's marketing approach seems strikingly similar to the semiotic approach of the message. In the semiotic approach, the message is a construction of signs, which, by interacting with the receiver, produces the meaning. The transmitter (the message transmitter) becomes less important. The focus is centered to the "text" and the way this is "read", the sense being born when the "reader" negotiates the "text". The negotiation takes place when the "reader" filtrates the message through the sieve of his cultural loading. A "target public" is a group which is specific to a certain Cultural Loading, a loading which deals with linguistic, logical, psychological and symbolic structures, which get out to meet the message and "negotiates" with the structures similar to it. When we are thinking in terms of the semiotic approach, we are handling the cultural determinism of communication, using the concepts of Kuhn and Gonseth (paradigm and referential). They open a new path in the market research, in the market segmentation and knowledge of the "target audiences".

    The purpose of this research is to identify communication barriers and needs for Deaf and hard-of-hearing (HOH) patients when they seek pharmaceutical care, and to better understand the impact of poor communication upon medication adherence and medication errors among this underserved population. Focus group discussion. Midwestern United States in September 2013 through April 2014. Deaf/HOH patients aged 18 years or older who used American Sign Language as their primary method of communication and were taking at least two long-term prescription medications. Qualitative themes. Many of the Deaf/HOH still perceived community pharmacists in a dispensing role and lacked an understanding of other services being offered in this setting. In addition, pharmacists who demonstrated a lack of sensitivity and patience towards the Deaf/HOH risk weakening the relationship between patient and provider. As a result, safe use of medications is compromised. Deaf and HOH patients have unique needs that pharmacists must understand and address. Effective communication and literacy assessment is essential to ensure safe medication use and optimal health outcomes. Pharmacist education and staff training are needed to increase awareness of this patient population's needs and to strengthen the patient-pharmacist relationship.

    This modern translation of Sophus Lie's and Friedrich Engel's “Theorie der Transformationsgruppen Band I” will allow readers to discover the striking conceptual clarity and remarkably systematic organizational thought of the original German text. Volume I presents a comprehensive introduction to the theory and is mainly directed towards the generalization of ideas drawn from the study of examples. The major part of the present volume offers an extremely clear translation of the lucid original. The first four chapters provide not only a translation, but also a contemporary approach, which will help present day readers to familiarize themselves with the concepts at the heart of the subject. The editor's main objective was to encourage a renewed interest in the detailed classification of Lie algebras in dimensions 1, 2 and 3, and to offer access to Sophus Lie's monumental Galois theory of continuous transformation groups, established at the end of the 19th Century. Lie groups are widespread in mathematics, p...

  3. Communication and Collective Consensus Making in Animal Groups via Mechanical Interactions

    Várkonyi, Péter L.

    2011-06-01

    Mechanical constraints have a strong influence on the dynamics and structure of granular aggregations. The contact forces within dense suspensions of active particles may give rise to intriguing phenomena, including anomalous density fluctuations, long-range orientational ordering, and spontaneous pattern formation. Various authors have proposed that these physical phenomena contribute to the ability of animal groups to move coherently. Our systematic numerical simulations confirm that spontaneous interactions of elongated individuals can trigger oriented motion in small groups. They are, however, insufficient in larger ones, despite their significant imprint on the group's internal structure. It is also demonstrated that preferred directions of motion of a minority of group members can be communicated to others solely by mechanical interactions. These findings strengthen the link between pattern formation in active nematics and the collective decision making of social animals.

  15. Fault Tolerance and Recovery for Group Communication Services in Distributed Networks

    2012-01-01

    Group communication services (GCSs) are becoming increasingly important as a wide field of promising applications has emerged to serve millions of users distributed across the world.However,it is challenging to make the service fault tolerance and scalable to fulfill the voluminous demand of users in a distributed network (DN).While many reliable group communication protocols have been dedicated to addressing such a challenge so as to accommodate the changes in the network,they are often costly or require complicated strategies to handle the service interruptions caused by node departures or link failures,which hinders the service practicability. In this paper,we present two schemes to address the challenges.The first one is a location-aware replication scheme called NS,which makes replicas in a dispersed fashion that enables the services on nodes to gain immunity of failures with different patterns (e.g.,network partition and single point failure) while keeping replication overhead low.The second one is a novel failure recovery scheme that exploits the independence between service recovery and structure recovery in time domain to achieve quick failure recovery.Our simulation results indicate that the two proposed schemes outperform the existing schemes and simple alternative schemes in service success rate,recovery latency,and communication cost.

    The Chinese Medical Doctor's Association asked us to develop a train-the-trainers program in doctor-patient communication and in teaching skills for a select group of Chinese health care professionals, who would then serve as trainers for practicing physicians throughout China. The request came in the context of increasing doctor-patient friction related, in part, to the dissolution of the socialist health care safety net in China. In this article we recount the implementation of our 5-day training program in Beijing. We explore cross-cultural issues that arose in presenting the program's two principal training domains: small group teaching and patient-centered doctor-patient communication. We also explore the linguistic challenges we encountered as non-Chinese speaking teachers. Finally, we reflect on the lessons learned from this project that may be of value to others called upon to export Western doctor-patient communications training to other cultures. In this age of increasing globalization, cross-cultural sharing of medical education represents a growing trend.

  20. On the Standard Approach to Renormalization Group Improvement

    CERN Document Server

    Chishtie, F A; Mann, R B; McKeon, D G C; Steele, T G

    2006-01-01

    Two approaches to renormalization-group improvement are examined: the substitution of the solutions of running couplings, masses and fields into perturbatively computed quantities is compared with the systematic sum of all the leading log (LL), next-to-leading log (NLL) etc. contributions to radiatively corrected processes, with n-loop expressions for the running quantities being responsible for summing N^{n}LL contributions. A detailed comparison of these procedures is made in the context of the effective potential V in the 4-dimensional O(4) massless $\\lambda \\phi^{4}$ model, showing the distinction between these procedures at two-loop order when considering the NLL contributions to the effective potential V.

  1. Integrating IPsec within OpenFlow Architecture for Secure Group Communication

    2014-01-01

    Network security protocols such as IPsec have been used for many years to ensure robust end-to-end communication and are impor-tant in the context of SDN. Despite the widespread installation of IPsec to date, per-packet protection offered by the protocol is not very compatible with OpenFlow and flow-like behavior. OpenFlow architecture cannot aggregate IPsec-ESP flows in transport mode or tunnel mode because layer-3 information is encrypted and therefore unreadable. In this paper, we propose using the Secu-rity Parameter Index (SPI) of IPsec within the OpenFlow architecture to identify and direct IPsec flows. This enables IPsec to con-form to the packet-based behavior of OpenFlow architecture. In addition, by distinguishing between IPsec flows, the architecture is particularly suited to secure group communication.

  3. On position-space renormalization group approach to percolation

    Science.gov (United States)

    Sahimi, Muhammad; Rassamdana, Hossein

    1995-02-01

    In a position-space renormalization group (PSRG) approach to percolation one calculates the probability R(p,b) that a finite lattice of linear size b percolates, where p is the occupation probability of a site or bond. A sequence of percolation thresholds p c (b) is then estimated from R(p c , b)=p c (b) and extrapolated to the limit b→∞ to obtain p c = p c (∞). Recently, it was shown that for a certain spanning rule and boundary condition, R(p c , ∞)=R c is universal, and since p c is not universal, the validity of PSRG approaches was questioned. We suggest that the equation R(p c , b)=α, where α is any number in (0,1), provides a sequence of p c (b)'s that always converges to p c as b→∞. Thus, there is an envelope from any point inside of which one can converge to p c . However, the convergence is optimal if α= R c . By calculating the fractal dimension of the sample-spanning cluster at p c , we show that the same is true about any critical exponent of percolation that is calculated by a PSRG method. Thus PSRG methods are still a useful tool for investigating percolation properties of disordered systems.

The advantages of such procedure are apparent: fewer (if any legal requirements, and, most importantly, the possibility to automate the surveillance. After a brief review of the pertinent literature, we offer three approaches that are designed to aid in the detection of not only terrorist cells, but also the command structures within the cells. The techniques are demonstrated by using a small illustration. The paper concludes by outlining limitations of the procedures described here.

    Cancer innovations, such as biobanking technologies, are continuously evolving to improve our understanding and knowledge about cancer prevention and treatment modalities. However, the public receives little communication about biobanking and is often unaware about this innovation until asked to donate biospecimens. It is the researchers' ethical duty to provide clear communications about biobanking and biospecimen research. Such information allows the public to understand biobanking processes and facilitates informed decision making about biospecimen donation. The aims of this paper are 1) to examine the importance of clear communication as an ethical imperative when conveying information about cancer innovations and 2) to illustrate the use of an organizing framework, the CLEAN ( C ulture, L iteracy, E ducation, A ssessment, and N etworking) Look approach for creating educational priming materials about the topic of biobanking.

    Congressional attention to Unmanned Aircraft Systems (UAS) has caused the Federal Aviation Administration (FAA) to move the National Airspace System (NAS) Integration project forward, but using guidelines, practices and procedures that are yet to be fully integrated with the FAA Aviation Management System. The real drive for change in the NAS will to come from both UAS operators and the government jointly seeing an accurate forecast of UAS usage demand data. This solid forecast information would truly get the attention of planners. This requires not an aggregate demand, but rather a picture of how the demand is spread across small to large UAS, how it is spread across a wide range of missions, how it is expected over time and where, in terms of geospatial locations, will the demand appear. In 2012 the Volpe Center performed a study of the overall future demand for UAS. This was done by aggregate classes of aircraft types. However, the realistic expected demand will appear in clusters of aircraft activities grouped by similar missions on a smaller geographical footprint and then growing from those small cells. In general, there is not a demand forecast that is tightly coupled to the real purpose of the mission requirements (e.g. in terms of real locations and physical structures such as wind mills to inspect, farms to survey, pipelines to patrol, etc.). Being able to present a solid basis for the demand is crucial to getting the attention of investment, government and other fiscal planners. To this end, Mosaic ATM under NASA guidance is developing a crowd sourced, demand forecast engine that can draw forecast details from commercial and government users and vendors. These forecasts will be vetted by a governance panel and then provide for a sharable accurate set of projection data. Our paper describes the project and the technical approach we are using to design and create access for users to the forecast system.

  10. Teaching and learning communication in medicine: a rhetorical approach.

    Science.gov (United States)

    Lingard, L; Haber, R J

    1999-05-01

    The language people use both makes possible and constrains the thoughts they can have. More than just a vehicle for ideas, language shapes ideas--and the practices that follow from them. Thus, in medical education, teaching students how to talk about medical cases also teaches them how to think about patients and medical work, and how to define their relationships to both. Without a theoretical model, however, teaching efforts in this domain tend to be implicit and ad hoc, which can lead to serious problems. Rhetoric is one science that can deepen understanding of communication and improve teaching of this clinical skill. Rhetoric systematically studies the relationships between communication and its effects, between how things are named and how they are experienced, between discourse and socialization. Bringing language to the foreground of education, rhetoric directs attention to the relationship between what medical students learn to say and what they learn to value, believe, and practice.

    2017-02-17

    In this narrative review, the author synthesizes the literature on homelessness across various disciplines (e.g., public health, social work, sociology, and communication) to demonstrate how the experiences of homelessness can be created, maintained, and reinforced through communication, including interpersonal interactions and public discourse. By conceptualizing homelessness as a culturally constructed and socially situated phenomenon, the author examines (a) the complex conceptualization of homelessness, (b) everyday violence faced by people who are homeless, and (c) coping strategies of people who are homeless. In summary, homelessness is a complex social phenomenon, involving tensions between individuals, families, and social systems, all of which are situated in the larger sociocultural and sociopolitical contexts of a specific time and place.

  15. A Bottom-Up Approach for Automatically Grouping Sensor Data Layers by their Observed Property

    Steve H.L. Liang

    2013-01-01

    Full Text Available The Sensor Web is a growing phenomenon where an increasing number of sensors are collecting data in the physical world, to be made available over the Internet. To help realize the Sensor Web, the Open Geospatial Consortium (OGC has developed open standards to standardize the communication protocols for sharing sensor data. Spatial Data Infrastructures (SDIs are systems that have been developed to access, process, and visualize geospatial data from heterogeneous sources, and SDIs can be designed specifically for the Sensor Web. However, there are problems with interoperability associated with a lack of standardized naming, even with data collected using the same open standard. The objective of this research is to automatically group similar sensor data layers. We propose a methodology to automatically group similar sensor data layers based on the phenomenon they measure. Our methodology is based on a unique bottom-up approach that uses text processing, approximate string matching, and semantic string matching of data layers. We use WordNet as a lexical database to compute word pair similarities and derive a set-based dissimilarity function using those scores. Two approaches are taken to group data layers: mapping is defined between all the data layers, and clustering is performed to group similar data layers. We evaluate the results of our methodology.

    Slater, S. J.; Slater, T. F.

    2013-12-01

    Modern science education reform documents propose that the teaching of contemporary students should focus on doing science, rather than simply memorizing science. Duschl, Schweingruber, and Shouse (2007) eloquently argue for four science proficiencies for students. Students should: (i) Know, use, and interpret scientific explanations of the natural world; (ii) Generate and evaluate scientific evidence and explanations; (iii) Understand the nature and development of scientific knowledge; and (iv) Participate productively in scientific practices and discourse. In response, scholars with the CAPER Center for Astronomy & Physics Education Research are creating and field-tested two separate instructional approaches. The first of these is a series of computer-mediated, inquiry learning experiences for non-science majoring undergraduates based upon an inquiry-oriented teaching approach framed by the notions of backwards faded-scaffolding as an overarching theme for instruction. Backwards faded-scaffolding is a strategy where the conventional and rigidly linear scientific method is turned on its head and students are first taught how to create conclusions based on evidence, then how experimental design creates evidence, and only at the end introduces students to the most challenging part of inquiry - inventing scientifically appropriate questions. Planetary science databases and virtual environments used by students to conduct scientific investigations include the NASA and JPL Solar System Simulator and Eyes on the Solar System as well as the USGS Moon and Mars Global GIS Viewers. The second of these is known widely as a Lecture-Tutorial approach. Lecture-Tutorials are self-contained, collaborative group activities. The materials are designed specifically to be easily integrated into the lecture course and directly address the needs of busy and heavily-loaded teaching faculty for effective, student-centered, classroom-ready materials that do not require a drastic course

    Language's intentional nature has been highlighted as a crucial feature distinguishing it from other communication systems. Specifically, language is often thought to depend on highly structured intentional action and mutual mindreading by a communicator and recipient. Whilst similar abilities in animals can shed light on the evolution of intentionality, they remain challenging to detect unambiguously. We revisit animal intentional communication and suggest that progress in identifying analogous capacities has been complicated by (i) the assumption that intentional (that is, voluntary) production of communicative acts requires mental-state attribution, and (ii) variation in approaches investigating communication across sensory modalities. To move forward, we argue that a framework fusing research across modalities and species is required. We structure intentional communication into a series of requirements, each of which can be operationalised, investigated empirically, and must be met for purposive, intentionally communicative acts to be demonstrated. Our unified approach helps elucidate the distribution of animal intentional communication and subsequently serves to clarify what is meant by attributions of intentional communication in animals and humans. © 2016 Cambridge Philosophical Society.

  4. Learning to Communicate Science: Stony Brook University's Approach

    Stony Brook University offers an unusual series of short courses to help science graduate students learn to communicate more effectively about science with people outside their disciplines, including the public, public officials, potential funders and employers, students, the press, and colleagues in other fields. The courses include six 1-credit (14-hour) modules in oral and written communication that rely on practice and interactive feedback. More than 120 master's and PhD students, from more than 16 departments, have taken at least one of the courses since spring 2011. Most students who try one module end up taking two or three. An additional course for medical and nursing students was added in fall 2012. The courses are offered in the School of Journalism and were developed by the Center for Communicating Science (CCS). CCS was founded in 2009, with the participation of Alan Alda, the actor, writer, and longtime advocate for science, who is a Visiting Professor at Stony Brook. The Communicating Science courses have received strong institutional support and enthusiastic reviews. They are required by two programs, an MA in Marine Conservation and Policy and an Advanced Certificate in Health Communications. Two successive Provosts have subsidized course costs for PhD students, and Graduate School leaders are working to establish a steady funding stream to allow expansion of the program. Our aspiration at CCS is for every science graduate student to receive some training in communicating about science to the public. Several factors have helped in establishing the program: --CCS' multidisciplinary nature helped build support, with participation by faculty from across the campus, including not only the natural sciences, engineering, and medicine, but journalism, theatre arts, and the Writing Program, as well as nearby Brookhaven National Laboratory and Cold Spring Harbor Laboratory. --Before offering courses, CCS conducted all-day workshops and high

    To compare veterinarians' and pet owners' perceptions of client expectations with respect to veterinarian-client communication and to identify related barriers and challenges to communication. Qualitative study based on focus group interviews. 6 pet owner focus groups (32 owners) and 4 veterinarian focus groups (24 companion animal veterinarians). Independent focus group sessions were conducted with standardized open-ended questions and follow-up probes. Content analysis was performed on transcripts of the focus group discussions. Five themes related to veterinarian-client communication were identified: educating clients (ie, explaining important information, providing information up front, and providing information in various forms), providing choices (ie, providing pet owners with a range of options, being respectful of owners' decisions, and working in partnership with owners), using 2-way communication (ie, using language clients understand, listening to what clients have to say, and asking the right questions), breakdowns in communication that affected the client's experience (ie, owners feeling misinformed, that they had not been given all options, and that their concerns had not been heard), and challenges veterinarians encountered when communicating with clients (ie, monetary concerns, client misinformation, involvement of > 1 client, and time limitations). Results suggested that several factors are involved in providing effective veterinarian-client communication and that breakdowns in communication can have an adverse effect on the veterinarian-client relationship.

    Sakshar Mahila Smooh (SMS) program was launched in rural areas of Haryana in India during 2008. A total of 6788 SMSs, each having 5-10 literate women, were equipped to enhance health communication. We carried out process evaluation of this program as an external agency. After a review of program documents, a random sample survey of Auxiliary Nurse Midwives (ANMs), SMS members, and village women was conducted. Out of four divisions of the state, one was randomly chosen, which had five districts. From 330 randomly chosen villages, 283 ANMs, 1164 SMS members, and 1123 village women were interviewed using a semi- structured interview schedule. Program inputs, processes, and outputs were compared in the five districts. Chi square was used for significance test. In the sampled division, out of 2009 villages, 1732 (86%) had functional SMS. In three years, SMS conducted 15036 group meetings, 2795 rallies, 2048 wall writings, and 803 competitions, and 44.5% of allocated budget was utilized. Most ANMs opined that SMSs are better health communicators. SMS members were aware about their roles and responsibilities. Majority of village women reported that SMS carry out useful health education activities. The characteristics of SMS members were similar but program performance was better in districts where health managers were proactive in program planning and monitoring. SMS Program has communicated health messages to majority of rural population, however, better planning & monitoring can improve program performance. Copyright © 2017 Elsevier Ltd.

    A quantum field model that incorporates Bose-condensed systems near their phase transition into a superfluid phase and velocity fluctuations is proposed. The stochastic Navier-Stokes equation is used for a generation of the velocity fluctuations. As such this model generalizes model F of critical dynamics. The field-theoretic action is derived using the Martin-Siggia-Rose formalism and path integral approach. The regime of equilibrium fluctuations is analyzed within the perturbative renormalization group method. The double (ε,δ)-expansion scheme is employed, where ε is a deviation from space dimension 4 and δ describes scaling of velocity fluctuations. The renormalization procedure is performed to the leading order. The main corollary gained from the analysis of the thermal equilibrium regime suggests that one-loop calculations of the presented models are not sufficient to make a definite conclusion about the stability of fixed points. We also show that critical exponents are drastically changed as a result of the turbulent background and critical fluctuations are in fact destroyed by the developed turbulence fluctuations. The scaling exponent of effective viscosity is calculated and agrees with expected value 4/3.

    2012-01-01

    We have witnessed the advent of the group-communication era in which everyone can speak out and communication is prevalent. Excess production capacity is the basic economic feature of the group- communication era, and it is also the social soil for its rise. The Internet offers a "physical space" for group- communication, which is constantly existent. Group communication has to some extent reduced the meaning conveyance and media monopoly of mass communication, and also offers opportunities and platforms for individuals, groups, enterprises and institutions to participate in the communication competition. There' re both competition and cooperation among mass communication, organizational communication and group communication, and the only way for win-win is to benefit from each other' s strength. Making full use of group communication can get more effects with less effort in Internet promotion and cultural marketing. What' s worthy of noticing, the intertwining of group communication such as micro-blogs, with interpersonal communication may cause rumors to become influential.%一个“人人都能发声,传播无处不在”的群体传播时代已经到来。产能过剩是群体传播时代的基本经济特征,也是其兴起的社会土壤。互联网为群体传播提供了无时不在的“物理空间”。群体传播在一定程度上消解了大众传播的意义传递和媒介垄断,又为个体、群体、企业和机构参与传播竞争,提供了机会和平台。大众传播、组织传播与群体传播,既存博弈又有合作,只有相互借力才能共赢。在网络推广、文化营销中,充分利用群体传播能够实现“四两拨千斤”的效果。值得注意的是,微博等群体传播与人际传播的交织,却是谣言产生影响力的根源。

    2017-04-01

    Flooding is a major hazard across Europe which, since, 1998 has caused over €52 million in damages and displaced over half a million people. Climate change is predicted to increase the risks posed by flooding in the future. The 2007 EU Flood Directive cemented the use of flood risk maps as a central tool in understanding and communicating flood risk. Following recent flooding in England, an urgent need to integrate people living at risk from flooding into flood management approaches, encouraging flood resilience and the up-take of resilient activities has been acknowledged. The effective communication of flood risk information plays a major role in allowing those at risk to make effective decisions about flood risk and increase their resilience, however, there are emerging concerns over the effectiveness of current approaches. The research presented explores current approaches to flood risk communication in England and the effectiveness of these methods in encouraging resilient actions before and during flooding events. The research also investigates how flood risk communications could be undertaken more effectively, using a novel participatory framework to integrate the perspectives of those living at risk. The research uses co-production between local communities and researchers in the environmental sciences, using a participatory framework to bring together local knowledge of flood risk and flood communications. Using a local competency group, the research explores what those living at risk from flooding want from flood communications in order to develop new approaches to help those at risk understand and respond to floods. Suggestions for practice are refined by the communities to co-produce recommendations. The research finds that current approaches to real-time flood risk communication fail to forecast the significance of predicted floods, whilst flood maps lack detailed information about how floods occur, or use scientific terminology which people at risk

  15. A non-perturbative approach to relativistic quantum communication channels

    Landulfo, Andre G S

    2016-01-01

    We investigate the transmission of both classical and quantum information between two arbitrary observers in globally hyperbolic spacetimes using a quantum field as a communication channel. The field is supposed to be in some arbitrary quasifree state and no choice of representation of its canonical commutation relations is made. Both sender and receiver posses some localized two-level quantum system with which they can interact with the quantum field to prepare the input and receive the output of the channel, respectively. The interaction between the two-level systems and the quantum field is such that one can trace out the field degrees of freedom exactly and thus obtain the quantum channel in a non-perturbative way. We end the paper determining the unassisted as well as the entanglement-assisted classical and quantum channel capacities.

    2016-01-01

    Full Text Available Introduction: The communication between faculty and students is a vital component of optimal facilitation of knowledge and learning. Various factors influence this dynamic. Aim: To assess communication levels between students and teachers in a dental college scenario via focus group discussion. Materials and Methods: The focus group discussion consisted of 10 groups; 5 groups representing the teachers, and 5 groups representing the students. Each group consisted of 6 participants. Hence there were a total of 30 teacher and 30 student participants. Focus group discussion was conducted for each of the groups for 30–45 min duration in the presence of a moderator and a note-taker. Open-ended questions were put across by the moderator to initiate and continue the discussions. The hand-written data taken by the note-taker were transcribed onto a computer on the same day of the discussion. Based on the transcription, domains were created for the student and teacher groups. Results: The issues raised by both the teacher and student groups in this focus group discussion were broadly classified into the following themes: (1 Past versus current scenario, (2 attitudes toward communication and learning, (3 hindrances to effective communication, and (4 potential solutions. Conclusions: Focus group discussion exposed many differences in the perceptions of teachers and students to communication. Each group, however, felt that bridging the teacher-student communication barrier was crucial to improve the teaching-learning experience. Many constructive solutions were provided by both the groups which can help to improve the quality of teaching-learning experience resulting in better quality of education.

  17. A Novel Approach for Improving Communication by Wavelength Utilization

    Directory of Open Access Journals (Sweden)

    Shrangesh Dahat

    2012-06-01

    Full Text Available Optical networks using wavelength division multiplexing (WDM technology modulate multiple channels over a single fiber. The most common architecture utilized for establishing communication in WDM optical networks is wavelength routing, where the communication between a source and a destination node is performed by setting up optical channels between them, called light-paths from the network perspective. In optical WDM networks, transmission of information along optical lines is advantageous since it has high transmission capacity, scalability, feasibility and also high reliability. But since large amount of information is being carried, any problem during transmission can lead to severe damage to the data being carried. In this paper, we propose to develop a routing and wavelength utilization algorithm which considers two constraints for selecting the best path. The two constraints are based on the available free load and the number of wavelength used in the link. Based on these constraints, two cost functions on load and wavelength are determined, which yields a combined cost function. For each pair of source and destination, the path with the minimum combined cost function is selected as the primary path for data transmission, allocating the sufficient wavelength. This study paper proposes a RWU algorithm for the problem of establishing the set of efficient light paths for a given set of connection requests. The effectiveness of the proposed RWU algorithm is demonstrated by simulation. This study divides the routing and wavelength allocation process in two step problem with a goal of minimizing Number of wavelength channel and number of wavelength conversion required. This algorithm thus provides a reliable path for the data transmission.

    2014-01-01

    Although English writing teachers paid great energy and time on students’writings in terms of revision of sentence structure, grammar, word choice, spelling and punctuation, students’English writing abilities have been progressed much less than expected. In other words, students’writings are characteristic of plain content, disorder of organization, simple sentence structure, generalized vocabulary, poor grammar. By the method of deduction, combined benefits and weaknesses of product-ori-ented approach with process-oriented approach, the communicative approach, comes to be applied in EFL writing for sopho-more college English majors. Communicative approach by combination of meaningful learning, the anticipation of reward, the in-trinsic motivation, the autonomy, language culture connection the communicative principle, the task principle brings much more effective success in writing teaching.

    On-site disposal cells are in use and being considered at several U.S. Department of Energy (USDOE) sites as the final disposition for large amounts of waste associated with cleanup of contaminated areas and facilities. These facilities are typically developed with regulatory oversight from States and/or the US Environmental Protection Agency (USEPA) in addition to USDOE. The facilities are developed to meet design standards for disposal of hazardous waste as well as the USDOE performance based standards for disposal of radioactive waste. The involvement of multiple and different regulators for facilities across separate sites has resulted in some differences in expectations for performance assessments and risk assessments (PA/RA) that are developed for the disposal facilities. The USDOE-EM Office of Site Restoration formed a working group to foster improved communication and sharing of information for personnel associated with these Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) disposal cells and work towards more consistent assumptions, as appropriate, for technical and policy considerations related to performance and risk assessments in support of a Record of Decision and Disposal Authorization Statement. The working group holds teleconferences, as needed, focusing on specific topics of interest. The topics addressed to date include an assessment of the assumptions used for performance assessments and risk assessments (PA/RAs) for on-site disposal cells, requirements and assumptions related to assessment of inadvertent intrusion, DOE Manual 435.1-1 requirements, and approaches for consideration of the long-term performance of liners and covers in the context of PAs. The working group has improved communication among the staff and oversight personnel responsible for onsite disposal cells and has provided a forum to identify and resolve common concerns.

    Full Text Available Problem statement: Communication and control are two main components in any Mechatronics system. They can be designed either by centralized or decentralized approach. Both approaches can be chosen based on application designed and specific requirements of the designer. In this study, decentralized or normally called distributed approach was selected to solved communication and control of a human adaptive mechanical system namely Intelligent Chair Tools (ICT. The ICT seating system is powered by thirty six intelligent pneumatic actuators to facilitate investigation of chair shapes from spring and damping effect of seating and backrest surface. Three studies are proposed from the sitting experiments namely chair shapes, chair spring and chair damping properties. Approach: PSoC microcontroller was selected based on its features of having configurable analog and digital blocks. Its flexible modules and programmable peripherals ease designer in designing the communication and control of ICT in improved and faster way. Three protocols of USB, SPI and I2C were used for the communication system of ICT using PSoC. Flow charts of each communication protocols algorithms were discussed. On the other hand, the control system used PSoC’s ADC and counter modules to read inputs of pressure and encoder respectively. PWM module is used to control the valve and data communication was achieved using I2C module. Block diagram of unified control was discussed for further understandings of the control algorithms. Results: The PSoC specification, development design and experimental evaluation of ICT system are presented and discussed. Three studies of chair shapes, chair spring property and chair damping property from sitting experiment were shown. Conclusion/Recommendations: The PSoC microcontroller selection was discussed and application of its distributed communication and control was successfully applied to ICT.

    2014-10-01

    The literature on techniques for improving student competency in therapeutic communication and interpersonal skills is limited. A simulation approach to enhance the learning of communication skills was developed to address these issues. Second-semester and senior nursing students participated in videorecorded standardized patient simulations, with senior students portraying the patient. Following simulated interactions, senior students provided feedback to junior students on their use of communication skills and other therapeutic factors. To integrate the learning experience, junior students completed a written assignment, in which they identified effective and noneffective communication; personal strengths and weaknesses; and use of genuineness, empathy, and positive regard. A videorecording of each student interaction gave faculty the opportunity to provide formative feedback to students. Student evaluations have been positive. Themes identified in student evaluations include the impact of seeing oneself, significance of practicing, getting below the surface in communication, and moving from insight to goal setting.

  6. A Multistage Control Mechanism for Group-Based Machine-Type Communications in an LTE System

    Directory of Open Access Journals (Sweden)

    Wen-Chien Hung

    2013-01-01

    Full Text Available When machine-type communication (MTC devices perform the long-term evolution (LTE attach procedure without bit rate limitations, they may produce congestion in the core network. To prevent this congestion, the LTE standard suggests using group-based policing to regulate the maximum bit rate of all traffic generated by a group of MTC devices. However, previous studies on the access point name-aggregate maximum bit rate based on group-based policing are relatively limited. This study proposes a multistage control (MSC mechanism to process the operations of maximum bit rate allocation based on resource-use information. For performance evaluation, this study uses a Markov chain with to analyze MTC application in a 3GPP network. Traffic flow simulations in an LTE system indicate that the MSC mechanism is an effective bandwidth allocation method in an LTE system with MTC devices. Experimental results show that the MSC mechanism achieves a throughput 22.5% higher than that of the LTE standard model using the group-based policing, and it achieves a lower delay time and greater long-term fairness as well.

    2011-01-01

    In this paper, we present a methodology for customized communication architecture synthesis that matches the communication requirements of the target application. This is an important problem, particularly for network-based implementations of complex applications. Our approach is based on using frequently encountered generic communication primitives as an alphabet capable of characterizing any given communication pattern. The proposed algorithm searches through the entire design space for a solution that minimizes the system total energy consumption, while satisfying the other design constraints. Compared to the standard mesh architecture, the customized architecture generated by the newly proposed approach shows about 36% throughput increase and 51% reduction in the energy required to encrypt 128 bits of data with a standard encryption algorithm.

    2010-01-01

    Network simulator software tools are often used to model the behaviors and interactions of applications, protocols, packets, and data links in terrestrial communication networks. Other software tools that model the physics, orbital dynamics, and RF characteristics of space systems have matured to allow for rapid, detailed analysis of space communication links. However, the absence of a unified toolset that integrates the two modeling approaches has encumbered the systems engineers tasked with the design, architecture, and analysis of complex space communication networks and systems. This paper presents the unified approach and describes the motivation, challenges, and our solution - the customization of the network simulator to integrate with astronautical analysis software tools for high-fidelity end-to-end simulation.

    Rapid advances in both genomic data acquisition and computational technology have encouraged the development and use of advanced engineering methods in the field of bioinformatics and computational genomics. Processes in molecular biology can be modeled through the use of these methods. Such processes include identification and annotation of all the functional elements in the genome, including genes and regulatory sequences, which are a fundamental challenge in genomics and computational biology. Since regulatory elements are often short and variable, their identification and discovery using computational algorithms is difficult. However, significant advances have been made in the computational methods for modeling and detection of DNA regulatory elements. This paper proposes a novel use of techniques and principles from communications engineering, coding, and information theory for modeling, identification, and analysis of genomic regulatory elements and biological sequences. The methods proposed are not only able to identify regulatory elements (REs) at their exact locations, but can also "interestingly" distinguish coding from non-coding regions. Therefore, the proposed methods can be utilized to identify genes in the mRNA sequence.

    The chapter introduces a socio-geographical concept of metropolitan journalism, taking into account political, economic and cultural factors. It discusses empirical examples from journalism practice in Germany to identify certain patterns of structure-building, news production, news mediation and audience engagement. In so doing, it uses a figurational approach as a heuristic, depicting current transformations of journalism in metropolitan setting. The chapter argues for a differentiation bet...

    Risk communication is fundamental in ensuring people are equipped with the knowledge needed to navigate varied risks. One generally well-regarded framework for the development of such communications is the mental models approach to risk communication (MMARC). Developed during the 1990s, the MMARC has been applied to a range of health, technological, and environmental risks. However, as yet, we know of no attempt to collate and review articles that evaluated communications developed using the MMARC. This article took a first step at addressing this gap by conducting a scoping review that aimed to begin to explore the fidelity with which the approach has been applied, explore whether there appeared to be sufficient studies to warrant a future systematic review, and identify future research questions. Although the initial search found over 100 articles explicitly applying the MMARC, only 12 of these developed a risk-related communication that was tested against a control (and thus included in the current review). All studies reported a positive effect of the MMARC versus control communication for at least some of the outcome measures (knowledge being the most prevalent). However, there was wide variation between studies including type of control, outcomes assessed, and only five studies reported adopting a randomized design. The review highlights both the need for greater fidelity in the way future studies operationalize the MMARC approach, and suggests that a full-scale systematic review of the MMARC literature appears justified, especially given the possibility of a large gray literature in this area.

  14. An Efficient Causal Group Communication Protocol for Free Scale Peer-to-Peer Networks

    Full Text Available In peer-to-peer (P2P overlay networks, a group of n (≥2 peer processes have to cooperate with each other. Each peer sends messages to every peer and receives messages from every peer in a group. In group communications, each message sent by a peer is required to be causally delivered to every peer. Most of the protocols designed to ensure causal message order are designed for networks with a plain architecture. These protocols can be adapted to use in free scale and hierarchical topologies; however, the amount of control information is O(n, where n is the number of peers in the system. Some protocols are designed for a free scale or hierarchical networks, but in general they force the whole system to accomplish the same order viewed by a super peer. In this paper, we present a protocol that is specifically designed to work with a free scale peer-to-peer network. By using the information about the network’s architecture and by representing message dependencies on a bit level, the proposed protocol ensures causal message ordering without enforcing super peers order. The designed protocol is simulated and compared with the Immediate Dependency Relation and the Dependency Sequences protocols to show its lower overhead.

    Drawing from self-determination theory (Deci & Ryan, 2002), we developed and tested an intervention to train fitness instructors to adopt a motivationally adaptive communication style when interacting with exercisers. This was a parallel group, two-arm quasi-experimental design. Participants in the intervention arm were 29 indoor cycling instructors (n = 10 for the control arm) and 246 class members (n = 75 for the control arm). The intervention consisted of face-to-face workshops, education/information video clips, group discussions and activities, brainstorming, individual planning, and practical tasks in the cycling studio. Instructors and exercisers responded to validated questionnaires about instructors' use of motivational strategies and other motivation-related variables before the first workshop and at the end of the third and final workshop (4 months later). Time × arm interactions revealed no significant effects, possibly due to the large attrition of instructors and exercisers in the control arm. Within-group analyses in the intervention arm showed that exercisers' perceptions of instructor motivationally adaptive strategies, psychological need satisfaction, and intentions to remain in the class increased over time. Similarly, instructors in the intervention arm reported being less controlling and experiencing more need satisfaction over time. These results offer initial promising evidence for the positive impact of the training.

    2007-06-01

    Full Text Available Proactive approach to communication network maintenance has the capability of enhancing the integrity and reliability of communication networks, as well as of reducing maintenance costs and overall number of incidents. This paper presents approaches to problem and incident prevention with the help of root-cause analysis, aligning that with the goal to foresee software performance. Implementation of proactive approach requires recognition of enterprise's current level of maintenance better insights into available approaches and tools, as well as their comparison, interoperability, integration and further development. The approach we are proposing and elaborating in this paper lies on the construction of a metamodel of the problem management of information technology, particularly the proactive problem management. The metamodel is derived from the original ITIL specification and presented in an object-oriented fashion by using structure (class diagrams conform to UML notation. Based on current research, appropriate metrics based on the concept of Key Performance Indicators is suggested.

  3. The Nonverbal Communication of Positive Emotions: An Emotion Family Approach.

    Sauter, Disa A

    2017-07-01

    This review provides an overview of the research on nonverbal expressions of positive emotions, organised into emotion families, that is, clusters sharing common characteristics. Epistemological positive emotions (amusement, relief, awe, and interest) are found to have distinct, recognisable displays via vocal or facial cues, while the agency-approach positive emotions (elation and pride) appear to be associated with recognisable visual, but not auditory, cues. Evidence is less strong for the prosocial emotions (love, compassion, gratitude, and admiration) in any modality other than touch, and there is little support for distinct recognisable signals of the savouring positive emotions (contentment, sensory pleasure, and desire). In closing, some limitations of extant work are noted and some proposals for future research are outlined.

  4. Group size, grooming and fission in primates: a modeling approach based on group structure.

    In social animals, fission is a common mode of group proliferation and dispersion and may be affected by genetic or other social factors. Sociality implies preserving relationships between group members. An increase in group size and/or in competition for food within the group can result in decrease certain social interactions between members, and the group may split irreversibly as a consequence. One individual may try to maintain bonds with a maximum of group members in order to keep group cohesion, i.e. proximity and stable relationships. However, this strategy needs time and time is often limited. In addition, previous studies have shown that whatever the group size, an individual interacts only with certain grooming partners. There, we develop a computational model to assess how dynamics of group cohesion are related to group size and to the structure of grooming relationships. Groups' sizes after simulated fission are compared to observed sizes of 40 groups of primates. Results showed that the relationship between grooming time and group size is dependent on how each individual attributes grooming time to its social partners, i.e. grooming a few number of preferred partners or grooming equally or not all partners. The number of partners seemed to be more important for the group cohesion than the grooming time itself. This structural constraint has important consequences on group sociality, as it gives the possibility of competition for grooming partners, attraction for high-ranking individuals as found in primates' groups. It could, however, also have implications when considering the cognitive capacities of primates.

    2017-01-01

    Full Text Available In this paper, an approach to biometric verification based on human body communication (HBC is presented for wearable devices. For this purpose, the transmission gain S21 of volunteer’s forearm is measured by vector network analyzer (VNA. Specifically, in order to determine the chosen frequency for biometric verification, 1800 groups of data are acquired from 10 volunteers in the frequency range 0.3 MHz to 1500 MHz, and each group includes 1601 sample data. In addition, to achieve the rapid verification, 30 groups of data for each volunteer are acquired at the chosen frequency, and each group contains only 21 sample data. Furthermore, a threshold-adaptive template matching (TATM algorithm based on weighted Euclidean distance is proposed for rapid verification in this work. The results indicate that the chosen frequency for biometric verification is from 650 MHz to 750 MHz. The false acceptance rate (FAR and false rejection rate (FRR based on TATM are approximately 5.79% and 6.74%, respectively. In contrast, the FAR and FRR were 4.17% and 37.5%, 3.37% and 33.33%, and 3.80% and 34.17% using K-nearest neighbor (KNN classification, support vector machines (SVM, and naive Bayesian method (NBM classification, respectively. In addition, the running time of TATM is 0.019 s, whereas the running times of KNN, SVM and NBM are 0.310 s, 0.0385 s, and 0.168 s, respectively. Therefore, TATM is suggested to be appropriate for rapid verification use in wearable devices.

  11. Approaches to managing uncertainty in people with life-limiting conditions: role of communication and palliative care.

    Science.gov (United States)

    Etkind, S N; Koffman, J

    2016-07-01

    Patients with any major illness can expect to experience uncertainty about the nature of their illness, its treatment and their prognosis. Prognostic uncertainty is a particular source of patient distress among those living with life-limiting disease. Uncertainty also affects professionals and it has been argued that the level of professional tolerance of uncertainty can affect levels of investigation as well as healthcare resource use. We know that the way in which uncertainty is recognised, managed and communicated can have important impacts on patients' treatment and quality of life. Current approaches to uncertainty in life-limiting illness include the use of care bundles and approaches that focus on communication and education. The experience in communicating in difficult situations that specialist palliative care professionals can provide may also be of benefit for patients with life-limiting illness in the context of uncertainty. While there are a number of promising approaches to uncertainty, as yet few interventions targeted at recognising and addressing uncertainty have been fully evaluated and further research is needed in this area.

    2012-03-01

    Full Text Available Abstract Background This research was a part of a contestable rapid response initiative launched by the Health Research Council of New Zealand and the Ministry of Health in response to the 2009 influenza A pandemic. The aim was to provide health authorities in New Zealand with evidence-based practical information to guide the development and delivery of effective health messages for H1N1 and other health campaigns. This study contributed to the initiative by providing qualitative data about community responses to key health messages in the 2009 and 2010 H1N1 campaigns, the impact of messages on behavioural change and the differential impact on vulnerable groups in New Zealand. Methods Qualitative data were collected on community responses to key health messages in the 2009 and 2010 Ministry of Health H1N1 campaigns, the impact of messages on behaviour and the differential impact on vulnerable groups. Eight focus groups were held in the winter of 2010 with 80 participants from groups identified by the Ministry of Health as vulnerable to the H1N1 virus, such as people with chronic health conditions, pregnant women, children, Pacific Peoples and Māori. Because this study was part of a rapid response initiative, focus groups were selected as the most efficient means of data collection in the time available. For Māori, focus group discussion (hui is a culturally appropriate methodology. Results Thematic analysis of data identified four major themes: personal and community risk, building community strategies, responsibility and information sources. People wanted messages about specific actions that they could take to protect themselves and their families and to mitigate any consequences. They wanted transparent and factual communication where both good and bad news is conveyed by people who they could trust. Conclusions The responses from all groups endorsed the need for community based risk management including information dissemination. Engaging

    2015-12-01

    Increasingly, the NHS is embracing the use of digital communication technology for communication between clinicians and patients. Policymakers deem digital clinical communication as presenting a solution to the capacity issues currently faced by general practice. There is some concern that these technologies may exacerbate existing inequalities in accessing health care. It is not known what impact they may have on groups who are already marginalised in their ability to access general practice. To assess the potential impact of the availability of digital clinician-patient communication on marginalised groups' access to general practice in the UK. Realist review in general practice. A four-step realist review process was used: to define the scope of the review; to search for and scrutinise evidence; to extract and synthesise evidence; and to develop a narrative, including hypotheses. Digital communication has the potential to overcome the following barriers for marginalised groups: practical access issues, previous negative experiences with healthcare service/staff, and stigmatising reactions from staff and other patients. It may reduce patient-related barriers by offering anonymity and offers advantages to patients who require an interpreter. It does not impact on inability to communicate with healthcare professionals or on a lack of candidacy. It is likely to work best in the context of a pre-existing clinician-patient relationship. Digital communication technology offers increased opportunities for marginalised groups to access health care. However, it cannot remove all barriers to care for these groups. It is likely that they will remain disadvantaged relative to other population groups after their introduction. © British Journal of General Practice 2015.

  18. Resource Dependent Radio Allocation For Battlefield Communications - A Data Model Approach

    Gregor Thomeczek

    2014-10-01

    Full Text Available Network Enabled Capability (NEC and the Land Open Systems Architecture (LOSA are novel approaches to enable interoperability between a heterogeneous collection of assets in the battlefield. These paradigms utilise an underlying network for cooperation between deployed battlefield equipment. NEC and LOSA have great potential to transform military communications and enhance integrated survivability as well as situational awareness, but the Achilles’ heel of NEC and LOSA is the wireless spectrum over which they must communicate. A noisy and dynamic battlefield wireless spectrum as well as an array of heterogeneous wireless communications equipment handling multiple types of data with different Quality of Service (QoS requirements requires a system which manages and allocates these communication resources effectively. This paper presents the High Availability Wireless Communications (HAWC system, a hardware agnostic communications controller middleware to manage any combination of existing and future multiband wireless resources. The system utilises a vehicle’s data model to gather information about available radio resources and enable LOSA by meeting communications data requirements and delivering appropriate QoS to the appropriate traffic in a fleet of vehicles. The functionality of the system is verified by using behavioural simulation on a virtual battlefield.

    To evaluate the feasibility of improving impaired social communication skills in persons with traumatic brain injury (TBI) and concomitant neurological or psychiatric conditions, using an intervention with evidence of efficacy in a TBI cohort without such complications. Cohort study with pre-post intervention and follow-up assessments. Thirty individuals with TBI ≥ 1 year post-injury and identified social communication problems participated in a group intervention to improve social communication skills. Group Interactive Structured Treatment (GIST) for Social Competence; 13 week, 1.5 hour manualized intervention. Profile of Pragmatic Impairment in Communication (PPIC); Social Communication Skills Questionnaire-Adapted (SCSQ-A); LaTrobe Communication Questionnaire (LCQ); Goal Attainment Scale (GAS), Awareness Questionnaire (AQ), Satisfaction with Life Scale (SWLS); Participation Assessment with Recombined Tools (PART). Participants made statistically significant gains on the SCSQ-A, GAS and SWLS post-treatment and at 6 months follow-up, using self and other ratings. Gains on the PPIC did not reach statistical significance but trended toward improvement. Treatment effects were not noted in analyses of the AQ or the PART. The LCQ showed statistically significant gains post-treatment and at follow-up. Participants showed improvement on subjective social communication skills measures post-treatment and at follow-up, demonstrating potential efficacy of the intervention in a broader population of persons with TBI, worthy of further investigation.

  20. An integrated approach to detecting communicative intent amid hyperkinetic movements in children.

    2011-09-01

    Children with hyperkinetic movement (HKM) often have limited access to traditional augmentative and alternative communication technologies (e.g., mechanical switches). To seek a communication solution for these children, this study explored the possibility that discernable biomechanical patterns, related to preference, exist amid HKM. We deployed a unified approach to analyse a child's movements, fusing caregiver and clinician observations with quantitative data (accelerations of the upper extremities). Two case studies were examined. In both, the accelerometer data identified preference at adjusted accuracies statistically above chance using a linear discriminant classifier. Visually, communicative movement patterns were identified in the first child (κ=0.25-0.27) but not in the second child (κ=0.03-0.11). Implications of this study include possible enhancement in communication and independence for these children.

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

    Science.gov (United States)

    Ord, Terry J; Garcia-Porta, Joan

    2012-07-05

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

    Progress toward understanding the links between interprofessional communication and issues of medical error has been slow. Recent research proposes that this delay may result from overlooking the complexities involved in interprofessional care. Medical education initiatives in this domain tend to simplify the complexities of team membership fluidity, rotation, and use of communication tools. A new theoretically informed research approach is required to take into account these complexities. To generate such an approach, we review two theories from the social sciences: Activity Theory and Knotworking. Using these perspectives, we propose that research into interprofessional communication and medical error can develop better understandings of (1) how and why medical errors are generated and (2) how and why gaps in team defenses occur. Such complexities will have to be investigated if students and practicing clinicians are to be adequately prepared to work safely in interprofessional teams.

    In the last few years, researchers have begun to investigate the emergence of novel forms of human communication in the laboratory. I survey this growing line of research, which may be called experimental semiotics, from three distinct angles. First, I situate the new approach in its theoretical and historical context. Second, I review a sample of studies that exemplify experimental semiotics. Third, I present an empirical study that illustrates how the new approach can help us understand the socio-cognitive underpinnings of human communication. The main conclusion of the paper will be that, by reproducing micro samples of historical processes in the laboratory, experimental semiotics offers new powerful tools for investigating human communication as a form of joint action.

  5. Manufacturing Communication: DCOM-MMS-based Approach for Flexible Manufacturing System

    Institute of Scientific and Technical Information of China (English)

    2005-01-01

    A design approach of manufacturing communication ispresented for flexible manufacturing system in this paper.The primary objective aims at making the flexible manufacturing control system provided with interoperability and rconfigurability.Based on describing manufacturing message specification (MMS) and distributed component object model (DCOM), a client/server manufacturing communication model is built with MMS standard and DCOM middleware, and thecommunication interfaces between MMS client and MMS server are designed with Microsoft interface definition language (MIDL) and abstract syntax notation one (ASN. 1) of MMS services. As a result, DCOM and MMS integration leads to such client/ server communication capabilities independent of different operating systems and manufacturing devices in flexible manufacturing automation environment. Finally, to verify the new design approach, a prototype system of robot control system has been implemented in MS 2000 Server/Professional Operating System and VC + + 6.0 Developer Environments.

    The article discusses the results of operationalizing Situational Strategic Planning adapted to the local level in health, considering the communicative approach and equity in a parish in Venezuela. Two innovative criteria were used: estimated health needs and analysis of the actors' potential for participation. The problems identified were compared to the corresponding article on rights in the Venezuelan Constitution. The study measured inequalities using health indicators associated with the selected problems; equity criteria were incorporated into the action proposals and communicative elements. Priority was assigned to the problem of "low case-resolving capacity in the health services network", and five critical points were selected for the action plan, which finally consisted of 6 operations and 21 actions. The article concludes that the combination of epidemiology and planning expands the situational explanation. Incorporation of the communicative approach and the equity dimension into Situational Strategic Planning allows empowering health management and helps decrease the gaps from inequality.

    Schuit, Dale; Diers, David; Vendrely, Ann

    2013-01-01

    This paper describes an active, collaborative learning project that occurred during a kinesiology course for first-year graduate students in physical (PT) and occupational therapy (OT) that was taught by faculty from both disciplines and designed to promote teamwork and integration of kinesiology concepts. The project required the students to describe and illustrate an assigned functional task, including the involved bony structure, joint mechanics, and muscle actions for joints of the lower extremities. Students from the PT and OT cohorts were intentionally mixed into groups of five students. They were provided with a topic for the assignment and a clear grading rubric. Each group gathered information from a variety of sources to address the topic. The final project was a poster that was presented to the class through an elaborate schedule that required all members of an individual group to present their poster to the group when they arrive at their poster. The presentations were well done and received high marks overall. Student scores were much less critical than faculty scores and included very few comments. The high scores awarded by course faculty indicated the thoroughness of the detail in the posters, as well as the preparedness of the students. An informally determined majority of students commented that being required to present the entire poster required them to comprehend material from the entire course, which we viewed as a positive learning experience.

    Online gamers form clans voluntarily to play together and to discuss their real and virtual lives. Although these clans have diverse goals, they seek to increase their rank in the game community by winning more battles. Communications among clan members and battles with other clans may influence the performance of a clan. In this study, we compared the effects of communication structure inside a clan, and battle networks among clans, with the performance of the clans. We collected battle histories, posts, and comments on clan pages from a Korean online game, and measured social network indices for communication and battle networks. Communication structures in terms of density and group degree centralization index had no significant association with clan performance. However, the centrality of clans in the battle network was positively related to the performance of the clan. If a clan had many battle opponents, the performance of the clan improved.

However, to engage students with the technology enhanced learning experiences calls for attentions on more the processes than the mere outcome of technology use. This study examines the common phenomenon in college campus where network technology, group activities and project works are available with the intention to explore how student performance of teamwork and learning is affected by the micro factors of group compositions, members’ roles and their communication behaviors. Results show that the group performed most procedure-, task-, and social-communication behaviors during the execution stage than that of preparation and completion stages. Additionally, members’ roles performed and interfered within these stages positively affected the project performance to different extent. [Article content in Chinese; Extended abstract in English

    2008-01-01

    For group decision-making problems with linguistic assessment information,a new method based on two-tuple and WC-OWA operator is proposed,in which the criteria's weights and the decision-makers' preference information might take the form of linguistic grade,or might be between two continuous linguistic grades,or might be linguistic interval,or might be default.In this method,all linguistic values are transformed into two-tuple,and an aggregative decision-making matrix is obtained by using interval operation.The group aggregative values of each criterion on alternatives are computed by using a WC-OWA operator,the aggregative values on alternatives are worked out,and transformed into two-tuple.And the rank of the alternatives is obtained by using the order property of two-tuple.An example shows the feasibility and effectiveness of the proposed method.

    2002-06-07

    The renormalization group method is applied to the study of homogeneous and flat Friedmann-Robertson-Walker type universes, filled with a causal bulk viscous cosmological fluid. The starting point of the study is the consideration of the scaling properties of the gravitational field equations, the causal evolution equation of the bulk viscous pressure and the equations of state. The requirement of scale invariance imposes strong constraints on the temporal evolution of the bulk viscosity coefficient, temperature and relaxation time, thus leading to the possibility of obtaining the bulk viscosity coefficient-energy density dependence. For a cosmological model with bulk viscosity coefficient proportional to the Hubble parameter, we perform the analysis of the renormalization group flow around the scale-invariant fixed point, thereby obtaining the long-time behaviour of the scale factor.

    Tröster, A

    2015-02-01

    The computation of the critical exponent η characterizing the universal elastic behavior of crystalline membranes in the flat phase continues to represent challenges to theorists as well as computer simulators that manifest themselves in a considerable spread of numerical results for η published in the literature. We present additional insight into this problem that results from combining Wilson's momentum shell renormalization-group method with the power of modern computer simulations based on the Fourier Monte Carlo algorithm. After discussing the ideas and difficulties underlying this combined scheme, we present a calculation of the renormalization-group flow of the effective two-dimensional Young modulus for momentum shells of different thickness. Extrapolation to infinite shell thickness allows us to produce results in reasonable agreement with those obtained by functional renormalization group or by Fourier Monte Carlo simulations in combination with finite-size scaling. Moreover, our method allows us to obtain a decent estimate for the value of the Wegner exponent ω that determines the leading correction to scaling, which in turn allows us to refine our numerical estimate for η previously obtained from precise finite-size scaling data.

    2017-04-01

    Thermal tensor networks constitute an efficient and versatile representation for quantum lattice models at finite temperatures. By Trotter-Suzuki decomposition, one obtains a D +1 dimensional TTN for the D -dimensional quantum system and then employs efficient renormalizaton group (RG) contractions to obtain the thermodynamic properties with high precision. The linearized tensor renormalization group (LTRG) method, which can be used to contract TTN efficiently and calculate the thermodynamics, is briefly reviewed and then generalized to a bilayer form. We dub this bilayer algorithm as LTRG++ and explore its performance in both finite- and infinite-size systems, finding the numerical accuracy significantly improved compared to single-layer algorithm. Moreover, we show that the LTRG++ algorithm in an infinite-size system is in essence equivalent to transfer-matrix renormalization group method, while reformulated in a tensor network language. As an application of LTRG++, we simulate an extended fermionic Hubbard model numerically, where the phase separation phenomenon, ground-state phase diagram, as well as quantum criticality-enhanced magnetocaloric effects, are investigated.

  13. Enabling Mobile Communications for the Needy: Affordability Methodology, and Approaches to Requalify Universal Service Measures

    Directory of Open Access Journals (Sweden)

    Louis-Francois PAU

    2009-01-01

    Full Text Available This paper links communications and media usage to social and household economics boundaries. It highlights that in present day society, communications and media are a necessity, but not always affordable, and that they furthermore open up for addictive behaviors which raise additional financial and social risks. A simple and efficient methodology compatible with state-of-the-art social and communications business statistics is developed, which produces the residual communications and media affordability budget and ultimately the value-at-risk in terms of usage and tariffs. Sensitivity analysis provides precious information on bottom-up communications and media adoption on the basis of affordability. This approach differs from the regulated but often ineffective Universal service obligation, which instead of catering for individual needs mostly addresses macro-measures helping geographical access coverage (e.g. in rural areas. It is proposed to requalify the Universal service obligations on operators into concrete measures, allowing, with unchanged funding, the needy to adopt mobile services based on their affordability constraints by bridging the gap to a standard tariff. Case data are surveyed from various countries. ICT policy recommendations are made to support widespread and socially responsible communications access.

    2017-06-24

    Israel is a high-income country with an advanced health system and universal health-care insurance. Overall, the health status has improved steadily over recent decades. We examined differences in morbidity, mortality, and risk factors for selected non-communicable diseases (NCDs) between subpopulation groups. Between 1975 and 2014, life expectancy in Israel steadily increased and is currently above the average life expectancy for the Organisation for Economic Co-operation and Development countries. Nevertheless, life expectancy has remained lower among Israeli Arabs than Israeli Jews, and this gap has recently widened. Age-adjusted mortality as a result of heart disease, stroke, or diabetes remains higher in Arabs, whereas age-adjusted incidence and mortality of cancer were higher among Jews. The prevalence of obesity and low physical activity in Israel is considerably higher among Arabs than Jews. Smoking prevalence is highest for Arab men and lowest for Arab women. Health inequalities are also evident by the indicators of socioeconomic position and in subpopulations, such as immigrants from the former Soviet Union, ultra-Orthodox Jews, and Bedouin Arabs. Despite universal health coverage and substantial improvements in the overall health of the Israeli population, substantial inequalities in NCDs persist. These differences might be explained, at least in part, by gaps in social determinants of health. The Ministry of Health has developed comprehensive programmes to reduce these inequalities between the major population groups. Sustained coordinated multisectoral efforts are needed to achieve a greater impact and to address other social inequalities. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Background: Communicable Disease Surveillance and reporting is one of the key elements to combat against diseases and their control. Fast and timely recognition of communicable diseases can be helpful in controlling of epidemics. One of the main sources of management of communicable diseases reporting is hospitals that collect communicable diseases’ reports and send them to health authorities. One of the focal problems and challenges in this regard is incomplete and imprecise reports from hospitals. In this study, while examining the implementation processes of the communicable diseases surveillance in hospitals, non-medical people who were related to the program have been studied by a qualitative approach. Methods: This study was conducted using qualitative content analysis method. Participants in the study included 36 informants, managers, experts associated with health and surveillance of communicable diseases that were selected using targeted sampling and with diverse backgrounds and work experience (different experiences in primary health surveillance and treatment, Ministry levels, university staff and operations (hospitals and health centers) and sampling was continued until arrive to data saturation. Results: Interviews were analyzed after the elimination of duplicate codes and integration of them. Finally, 73 codes were acquired and categorized in 6 major themes and 21 levels. The main themes included: policy making and planning, development of resources, organizing, collaboration and participation, surveillance process, and monitoring and evaluation of the surveillance system. In point of interviewees, attention to these themes is necessary to develop effective and efficient surveillance system for communicable diseases. Conclusion: Surveillance system in hospitals is important in developing proper macro - policies in health sector, adoption of health related decisions and preventive plans appropriate to the existing situation.
