Roter, Debra L; Wexler, Randy; Naragon, Phyllis; Forrest, Brian; Dees, Jason; Almodovar, Astrid; Wood, Julie

2012-09-01

The objective was to evaluate parallel patient and physician computer-mediated communication skill training on participants' report of skill use and patient satisfaction. Separate patient and clinician web-tools comprised of over 500, 10-s video clips demonstrating patient-centered skills in various ways. Four clinician members of the American Academy of Family Physicians National Research Network participated by enrolling 194 patients into a randomized patient trial and 29 physicians into a non-randomized clinician trial of respective interventions. All participants completed baseline and follow-up self-report measures of visit communication and satisfaction. Intervention patients reported using more skills than controls in five of six skill areas, including identification of problems/concerns, information exchange, treatment adherence, shared decision-making and interpersonal rapport (all p<.05); post intervention, physicians reported using more skills in the same 5 areas (all p<.01). Intervention group patients reported higher levels of satisfaction than controls in five of six domains (all p<.05). Communication skill training delivered in a computer mediated format had a positive and parallel impact on both patient and clinician reported use of patient-centered communication and in patient satisfaction. Computer-mediated interventions are cost and time effective thereby increasing patient and clinician willingness to undertake training. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Conducting Creativity Brainstorming Sessions in Small and Medium-Sized Enterprises Using Computer-Mediated Communication Tools

NASA Astrophysics Data System (ADS)

Murthy, Uday S.

A variety of Web-based low cost computer-mediated communication (CMC) tools are now available for use by small and medium-sized enterprises (SME). These tools invariably incorporate chat systems that facilitate simultaneous input in synchronous electronic meeting environments, allowing what is referred to as “electronic brainstorming.” Although prior research in information systems (IS) has established that electronic brainstorming can be superior to face-to-face brainstorming, there is a lack of detailed guidance regarding how CMC tools should be optimally configured to foster creativity in SMEs. This paper discusses factors to be considered in using CMC tools for creativity brainstorming and proposes recommendations for optimally configuring CMC tools to enhance creativity in SMEs. The recommendations are based on lessons learned from several recent experimental studies on the use of CMC tools for rich brainstorming tasks that require participants to invoke domain-specific knowledge. Based on a consideration of the advantages and disadvantages of the various configuration options, the recommendations provided can form the basis for selecting a CMC tool for creativity brainstorming or for creating an in-house CMC tool for the purpose.

[Web-ring of sites for pathologists in the internet: a computer-mediated communication environment].

PubMed

Khramtsov, A I; Isianov, N N; Khorzhevskiĭ, V A

2009-01-01

The recently developed Web-ring of pathology-related Web-sites has transformed computer-mediated communications for Russian-speaking pathologists. Though the pathologists may be geographically dispersed, the network provides a complex of asynchronous and synchronous conferences for the purposes of diagnosis, consultations, education, communication, and collaboration in the field of pathology. This paper describes approaches to be used by participants of the pathology-related Web-ring. The approaches are analogous to the tools employed in telepathology and digital microscopy. One of the novel methodologies is the use of Web-based conferencing systems, in which the whole slide digital images of tissue microarrays were jointly reviewed online by pathologists at distant locations. By using ImageScope (Aperio Technologies) and WebEx connect desktop management technology, they shared presentations and images and communicated in realtime. In this manner, the Web-based forums and conferences will be a powerful addition to a telepathology.

Toward a framework for computer-mediated collaborative design in medical informatics.

PubMed

Patel, V L; Kaufman, D R; Allen, V G; Shortliffe, E H; Cimino, J J; Greenes, R A

1999-09-01

The development and implementation of enabling tools and methods that provide ready access to knowledge and information are among the central goals of medical informatics. The need for multi-institutional collaboration in the development of such tools and methods is increasingly being recognized. Collaboration involves communication, which typically involves individuals who work together at the same location. With the evolution of electronic modalities for communication, we seek to understand the role that such technologies can play in supporting collaboration, especially when the participants are geographically separated. Using the InterMed Collaboratory as a subject of study, we have analyzed their activities as an exercise in computer- and network-mediated collaborative design. We report on the cognitive, sociocultural, and logistical issues encountered when scientists from diverse organizations and backgrounds use communications technologies while designing and implementing shared products. Results demonstrate that it is important to match carefully the content with the mode of communication, identifying, for example, suitable uses of E-mail, conference calls, and face-to-face meetings. The special role of leaders in guiding and facilitating the group activities can also be seen, regardless of the communication setting in which the interactions occur. Most important is the proper use of technology to support the evolution of a shared vision of group goals and methods, an element that is clearly necessary before successful collaborative designs can proceed.

A case study on support for students' thinking through computer-mediated communication.

PubMed

Sannomiya, M; Kawaguchi, A

2000-08-01

This is a case study on support for thinking through computer-mediated communication. Two graduate students were supervised in their research using computer-mediated communication, which was asynchronous and written; the supervisor was not present. The students' reports pointed out there was more planning and editing and low interactivity in this approach relative to face-to-face communication. These attributes were confirmed by their supervisor's report. The students also suggested that the latter was effective in support of a production stage of thinking in research, while the former approach was effective in support of examination of thinking. For distance education to be successful, an appropriate combination of communication media must consider students' thinking stages. Finally, transient and permanent effects should be discriminated in computer-mediated communication.

PubMed

Gillespie-Lynch, Kristen; Kapp, Steven K; Shane-Simpson, Christina; Smith, David Shane; Hutman, Ted

2014-12-01

An online survey compared the perceived benefits and preferred functions of computer-mediated communication of participants with (N  =  291) and without ASD (N  =  311). Participants with autism spectrum disorder (ASD) perceived benefits of computer-mediated communication in terms of increased comprehension and control over communication, access to similar others, and the opportunity to express their true selves. They enjoyed using the Internet to meet others more, and to maintain connections with friends and family less, than did participants without ASD. People with ASD enjoyed aspects of computer-mediated communication that may be associated with special interests or advocacy, such as blogging, more than did participants without ASD. This study suggests that people with ASD may use the Internet in qualitatively different ways from those without ASD. Suggestions for interventions are discussed.

NASA Astrophysics Data System (ADS)

Osesina, O. Isaac; McIntire, John P.; Havig, Paul R.; Geiselman, Eric E.; Bartley, Cecilia; Tudoreanu, M. Eduard

2012-06-01

Identifying social network (SN) links within computer-mediated communication platforms without explicit relations among users poses challenges to researchers. Our research aims to extract SN links in internet chat with multiple users engaging in synchronous overlapping conversations all displayed in a single stream. We approached this problem using three methods which build on previous research. Response-time analysis builds on temporal proximity of chat messages; word context usage builds on keywords analysis and direct addressing which infers links by identifying the intended message recipient from the screen name (nickname) referenced in the message [1]. Our analysis of word usage within the chat stream also provides contexts for the extracted SN links. To test the capability of our methods, we used publicly available data from Internet Relay Chat (IRC), a real-time computer-mediated communication (CMC) tool used by millions of people around the world. The extraction performances of individual methods and their hybrids were assessed relative to a ground truth (determined a priori via manual scoring).

Computers and the internet: tools for youth empowerment.

PubMed

Valaitis, Ruta K

2005-10-04

Youth are often disenfranchised in their communities and may feel they have little voice. Since computers are an important aspect of youth culture, they may offer solutions to increasing youth participation in communities. This qualitative case study investigated the perceptions of 19 (predominantly female) inner-city school youth about their use of computers and the Internet in a school-based community development project. Youth working with public health nurses in a school-based community development project communicated with local community members using computer-mediated communication, surveyed peers online, built websites, searched for information online, and prepared project materials using computers and the Internet. Participant observation, semistructured interviews, analysis of online messages, and online- and paper-based surveys were used to gather data about youth's and adults' perceptions and use of the technologies. Constant comparison method and between-method triangulation were used in the analysis to satisfy the existence of themes. Not all youth were interested in working with computers. Some electronic messages from adults were perceived to be critical, and writing to adults was intimidating for some youth. In addition, technical problems were experienced. Despite these barriers, most youth perceived that using computers and the Internet reduced their anxiety concerning communication with adults, increased their control when dealing with adults, raised their perception of their social status, increased participation within the community, supported reflective thought, increased efficiency, and improved their access to resources. Overall, youth perceived computers and the Internet to be empowering tools, and they should be encouraged to use such technology to support them in community initiatives.

Virtual collaboration: face-to-face versus videoconference, audioconference, and computer-mediated communications

NASA Astrophysics Data System (ADS)

Wainfan, Lynne; Davis, Paul K.

2004-08-01

As we increase our reliance on mediated communication, it is important to be aware the media's influence on group processes and outcomes. A review of 40+ years of research shows that all media-videoconference, audioconference, and computer-mediated communication--change the context of the communication to some extent, reducing cues used to regulate and understand conversation, indicate participants' power and status, and move the group towards agreement. Text-based computer-mediated communication, the "leanest" medum, reduces status effects, domination, and consensus. This has been shown useful in broadening the range of inputs and ideas. However, it has also been shown to increase polarization, deindividuation, and disinhibition, and the time to reach a conclusion. For decision-making tasks, computer-mediated communication can increase choice shift and the likelihood of more risky or extreme decisions. In both videoconference and audioconference, participants cooperate less with linked collaborators, and shift their opinions toward extreme options, compared with face-to-face collaboration. In videoconference and audioconference, local coalitions can form where participants tend to agree more with those in the same room than those on the other end of the line. There is also a tendency in audioconference to disagree with those on the other end of the phone. This paper is a summary of a much more extensive forthcoming report; it reviews the research literature and proposes strategies to leverage the benefits of mediated communication while mitigating its adverse effects.

Design Requirements for Communication-Intensive Interactive Applications

NASA Astrophysics Data System (ADS)

Bolchini, Davide; Garzotto, Franca; Paolini, Paolo

Online interactive applications call for new requirements paradigms to capture the growing complexity of computer-mediated communication. Crafting successful interactive applications (such as websites and multimedia) involves modeling the requirements for the user experience, including those leading to content design, usable information architecture and interaction, in profound coordination with the communication goals of all stakeholders involved, ranging from persuasion to social engagement, to call for action. To face this grand challenge, we propose a methodology for modeling communication requirements and provide a set of operational conceptual tools to be used in complex projects with multiple stakeholders. Through examples from real-life projects and lessons-learned from direct experience, we draw on the concepts of brand, value, communication goals, information and persuasion requirements to systematically guide analysts to master the multifaceted connections of these elements as drivers to inform successful communication designs.

Computer-mediated interdisciplinary teams: theory and reality.

PubMed

Vroman, Kerryellen; Kovacich, Joann

2002-05-01

The benefit of experience, tempered with the wisdom of hindsight and 5 years of text-based, asynchronous, computer-mediated, interdisciplinary team communications, provides the energy, insights and data shared in this article. Through the theoretical lens of group dynamics and the epistemology of interdisciplinary teaming, we analyze the interactions of a virtual interdisciplinary team to provide an understanding and appreciation of collaborative interdisciplinary communication in the context of interactive technologies. Whilst interactive technologies may require new patterns of language similar to that of learning a foreign language, what is communicated in the interdisciplinary team process does not change. Most important is the recognition that virtual teams, similar to their face-to-face counterparts, undergo the same challenges of interdisciplinary teaming and group developmental processes of formation: forming, storming, norming, performing, and transforming. After examining these dynamics of communication and collaboration in the context of the virtual team, the article concludes with guidelines facilitating interdisciplinary team computer-mediated communication.

Computer-mediated communication and time pressure induce higher cardiovascular responses in the preparatory and execution phases of cooperative tasks.

PubMed

Costa Ferrer, Raquel; Serrano Rosa, Miguel Ángel; Zornoza Abad, Ana; Salvador Fernández-Montejo, Alicia

2010-11-01

The cardiovascular (CV) response to social challenge and stress is associated with the etiology of cardiovascular diseases. New ways of communication, time pressure and different types of information are common in our society. In this study, the cardiovascular response to two different tasks (open vs. closed information) was examined employing different communication channels (computer-mediated vs. face-to-face) and with different pace control (self vs. external). Our results indicate that there was a higher CV response in the computer-mediated condition, on the closed information task and in the externally paced condition. These role of these factors should be considered when studying the consequences of social stress and their underlying mechanisms.

The associations among computer-mediated communication, relationships, and well-being.

PubMed

Schiffrin, Holly; Edelman, Anna; Falkenstern, Melissa; Stewart, Cassandra

2010-06-01

Social support provided by interpersonal relationships is one of the most robust correlates of well-being. Self-disclosure serves as a basic building block of these relationships. With the rapid growth of the Internet in recent years, the question remains how self-disclosure, and subsequently relationships and well-being, differ when people communicate over the Internet rather than in person. The purpose of this article is to describe current Internet usage patterns as well as explore the association of Internet usage and well-being. Additionally, it directly compares the perceived benefits of face-to-face communication and computer-mediated communication. A questionnaire was administered to 99 undergraduates to measure Internet usage patterns, communication partners, self-disclosure, extraversion, and subjective well-being. Although Internet communication was found to be common, individuals perceived computer-mediated communication to be less useful than face-to-face communication. In addition, increased Internet usage was associated with decreased well-being. Implications are discussed in terms of a new Internet paradox in which people increasingly use the Internet for communication, although they perceive it to be less beneficial than face-to-face interactions and it is associated with reduced well-being.

2008-01-01

The study examined the use of computer-mediated communication (CMC) among individuals involved in a conflict sparked by the appointment of an administrator as president-designate of Gallaudet University in 2006. CMC was defined as forms of communication used for transmitting (sharing) information through networks with digital devices. There were 662 survey respondents. Respondents reported overwhelmingly (98%) that they used CMC to communicate. Students and alumni reported CMC use in larger proportions than any other group. The favorite devices among all respondents were Sidekicks, stationary computers, and laptops. Half of all respondents also reported using some form of video device. Nearly all reported using e-mail; respondents also identified Web surfing, text messaging, and blogging as popular CMC activities. The authors plan another article reporting on computer and electronic technology use as a mechanism connecting collective identity to social movements.

An observation tool to study air traffic control and flightdeck collaboration.

PubMed

Cox, Gemma; Sharples, Sarah; Stedmon, Alex; Wilson, John

2007-07-01

The complex systems of the flightdeck (FD) and the Air Traffic Control Centre (ATC) are characterised by numerous concurrently operating and interacting communication channels between people and between people and machines/computer systems. This paper describes work in support of investigating the impact of changes to technologies and responsibilities within this system with respect to human factors. It focuses primarily on the introduction of datalink (text-based communication rather than traditional radio communication) and the move towards freeflight (pilot-mediated air traffic control). Air traffic management investigations have outlined these specific changes as strategies to enable further increases in the volume of air traffic. A systems approach was taken and field studies were conducted. Small numbers of domain experts such as air traffic controllers (ATCOs) were involved in the field-based observations of how people interact with systems and each other. This paper summarises the overall research approach taken and then specifically reports on the field-based observations including the justification, development, and findings of the observation tool used. The observation tool examined information propagation through the air traffic control-flightdeck (ATC-FD) system, and resulted in models of possible information trajectories through the system.

Experiences of women with breast cancer: exchanging social support over the CHESS computer network.

PubMed

Shaw, B R; McTavish, F; Hawkins, R; Gustafson, D H; Pingree, S

2000-01-01

Using an existential-phenomenological approach, this paper describes how women with breast cancer experience the giving and receiving of social support in a computer-mediated context. Women viewed their experiences with the computer-mediated support group as an additional and unique source of support in facing their illness. Anonymity within the support group fostered equalized participation and allowed women to communicate in ways that would have been more difficult in a face-to-face context. The asynchronous communication was a frustration to some participants, but some indicated that the format allowed for more thoughtful interaction. Motivations for seeking social support appeared to be a dynamic process, with a consistent progression from a position of receiving support to that of giving support. The primary benefits women received from participation in the group were communicating with other people who shared similar problems and helping others, which allowed them to change their focus from a preoccupation with their own sickness to thinking of others. Consistent with past research is the finding that women in this study expressed that social support is a multidimensional phenomenon and that their computer-mediated support group provided abundant emotional support, encouragement, and informational support. Excerpts from the phenomenological interviews are used to review and highlight key theoretical concepts from the research literatures on computer-mediated communication, social support, and the psychosocial needs of women with breast cancer.

Leveraging Social Computing for Personalized Crisis Communication using Social Media.

PubMed

Leykin, Dmitry; Aharonson-Daniel, Limor; Lahad, Mooli

2016-03-24

The extensive use of social media in modern life redefines social interaction and communication. Communication plays an important role in mitigating, or exacerbating, the psychological and behavioral responses to critical incidents and disasters. As recent disasters demonstrated, people tend to converge to social media during and following emergencies. Authorities can then use this media and other computational methods to gain insights from the public, mainly to enhance situational awareness, but also to improve their communication with the public and public adherence to instructions. The current review presents a conceptual framework for studying psychological aspects of crisis and risk communication using the social media through social computing. Advanced analytical tools can be integrated in the processes and objectives of crisis communication. The availability of the computational techniques can improve communication with the public by a process of Hyper-Targeted Crisis Communication. The review suggests that using advanced computational tools for target-audience profiling and linguistic matching in social media, can facilitate more sensitive and personalized emergency communication.

New diagnostic tool for robotic psychology and robotherapy studies.

PubMed

Libin, Elena; Libin, Alexander

2003-08-01

Robotic psychology and robotherapy as a new research area employs a systematic approach in studying psycho-physiological, psychological, and social aspects of person-robot communication. An analysis of the mechanisms underlying different forms of computer-mediated behavior requires both an adequate methodology and research tools. In the proposed article we discuss the concept, basic principles, structure, and contents of the newly designed Person-Robot Complex Interactive Scale (PRCIS), proposed for the purpose of investigating psychological specifics and therapeutic potentials of multilevel person-robot interactions. Assuming that human-robot communication has symbolic meaning, each interactive pattern evaluated via the newly developed scale is assigned certain psychological value associated with the person's past life experiences, likes and dislikes, emotional, cognitive, and behavioral traits or states. PRCIS includes (1) assessment of a person's individual style of communication with the robotic creature based on direct observations; (2) the participant's evaluation of his/her new experiences with an interactive robot and evaluation of its features, advantages and disadvantages, as well as past experiences with modern technology; and (3) the instructor's overall evaluation of the session.

Like an extended family: Relationships that emerge when older caregivers use written messages to communicate in an ICT-based healthcare service.

PubMed

Solli, Hilde; Bjørk, Ida Torunn; Hvalvik, Sigrun; Hellesø, Ragnhild

2018-03-01

To explore the relationships that emerge amongst caregivers of persons with dementia and stroke when caregivers use written messages as their communication tool in a closed information and communication technology (ICT)-based support group. An explorative design with a qualitative approach was used that applied systematic text condensation (STC) to analyse 173 written messages extracted from a web forum. Empathetic, empowering and familiar relationships emerged amongst peers of older caregivers when the caregivers used written messages as their communication tool. The empathetic relationship was characterised by sincerity and openness when the caregivers shared emotions related to caregiving. The empowering relationship reflected a fellowship based on solidarity influenced by a sense of optimism and a willingness to share knowledge to support one another in overcoming challenges. In the familiar relationship, the caregivers were thoughtful and good-humoured with one another and displayed an attitude of consideration towards one another, as in an extended family. The use of computer-mediated communication in health care service will change the context of establishing and maintaining interpersonal relationships. Therefore, greater knowledge regarding how the peers of caregivers interact with one another is vital so nurses may better support and educate ICT-based support groups.

2018-03-16

The aim of this study is to explore how computer mediated communication has been used by a variety of healthcare,professionals to support their patients and discuss the implication that this may have for future practice. A systematized review of the literature. A review of empirical studies within the literature was carried out in April 2016 in CINAHL, MEDLINE, ASSIA, BNI, Psychinfo, and Web of Science databases. The databases searched produced 2930 titles, of which 190 publications were considered relevant to the objectives. Titles and abstracts were then reviewed and duplicates removed producing 67 publications. Exclusion and inclusion criteria were applied. The inclusion criteria were (1) interventions that facilitate two-way communication between any healthcare professional and their patients via a computer; (2) Interventions aimed at providing any type of support e.g. emotional, tangible, informational, or esteem support; (3) English language; (4) Primary empirical studies. Data quality was assessed and thematic analysis applied. Thirty-one publications were included in this study. Intervention types included Email (n = 8), Videoconferencing (n = 7), Online Social Support Groups (n = 9) and multifaceted interventions (n = 7). Three themes emerged from the data including increasing access to healthcare, adding value to healthcare delivery and improving patient outcomes. Twenty-five (81%) of the studies found that computer mediated communication could produce positive effects. Computer mediated communication could be both what patients want and a way of delivering support to patients in a resource tight environment. This has implications for a range of health support needs and professionals including nurses, midwives and allied healthcare professionals. Reviewing the lessons learnt will ensure future interventions are tailored to the support needs of the patients, carefully planned and mindful of the risks. Copyright © 2018 Elsevier Ltd.

Clinical results of HIS, RIS, PACS integration using data integration CASE tools

NASA Astrophysics Data System (ADS)

Taira, Ricky K.; Chan, Hing-Ming; Breant, Claudine M.; Huang, Lu J.; Valentino, Daniel J.

1995-05-01

Current infrastructure research in PACS is dominated by the development of communication networks (local area networks, teleradiology, ATM networks, etc.), multimedia display workstations, and hierarchical image storage architectures. However, limited work has been performed on developing flexible, expansible, and intelligent information processing architectures for the vast decentralized image and text data repositories prevalent in healthcare environments. Patient information is often distributed among multiple data management systems. Current large-scale efforts to integrate medical information and knowledge sources have been costly with limited retrieval functionality. Software integration strategies to unify distributed data and knowledge sources is still lacking commercially. Systems heterogeneity (i.e., differences in hardware platforms, communication protocols, database management software, nomenclature, etc.) is at the heart of the problem and is unlikely to be standardized in the near future. In this paper, we demonstrate the use of newly available CASE (computer- aided software engineering) tools to rapidly integrate HIS, RIS, and PACS information systems. The advantages of these tools include fast development time (low-level code is generated from graphical specifications), and easy system maintenance (excellent documentation, easy to perform changes, and centralized code repository in an object-oriented database). The CASE tools are used to develop and manage the `middle-ware' in our client- mediator-serve architecture for systems integration. Our architecture is scalable and can accommodate heterogeneous database and communication protocols.

2013-05-01

The study examined how computer mediated tools, blended with traditional forms of teaching activity supported undergraduate pre-registration nursing students on international placement and for those students unable to go out into the world, how could this world be brought to their home campus? The researchers sought to examine whether synchronous online face to face contact using Skype, improved support and communication for students nursing overseas and if cultural awareness was developed for those nursing students who stayed on native soil. Data was collected using focus groups and online questionnaires. Themes arising from the thematic analysis of the narratives included operational issues, pastoral care, academic and peer support and cultural awareness and development. The use of Blended Learning tools such as Skype and weblogs were found to be extremely beneficial as a form of online communication and support for students undertaking an international placement. In relation to cultural awareness further work is required. Copyright © 2012 Elsevier Ltd. All rights reserved.

Designing Effective Persuasive Systems Utilizing the Power of Entanglement: Communication Channel, Strategy and Affect

NASA Astrophysics Data System (ADS)

Li, Haiqing; Chatterjee, Samir

With rapid advances in information and communication technology, computer-mediated communication (CMC) technologies are utilizing multiple IT platforms such as email, websites, cell-phones/PDAs, social networking sites, and gaming environments. However, no studies have compared the effectiveness of a persuasive system using such alternative channels and various persuasive techniques. Moreover, how affective computing impacts the effectiveness of persuasive systems is not clear. This study proposes (1) persuasive technology channels in combination with persuasive strategies will have different persuasive effectiveness; (2) Adding positive emotion to a message that leads to a better overall user experience could increase persuasive effectiveness. The affective computing or emotion information was added to the experiment using emoticons. The initial results of a pilot study show that computer-mediated communication channels along with various persuasive strategies can affect the persuasive effectiveness to varying degrees. These results also shows that adding a positive emoticon to a message leads to a better user experience which increases the overall persuasive effectiveness of a system.

A psychosocial comparison of computer-mediated and face-to-face language use among severely disturbed adolescents.

PubMed

Zimmerman, D P

1987-01-01

This study analyzes the content of communications among 18 severely disturbed adolescents. Interactions were recorded from two sources: computer-based "conferences" for the group, and small group face-to-face sessions which addressed similar topics. The purpose was to determine whether there are important differences in indications of psychological state, interpersonal interest, and expressive style. The research was significant, given the strong attraction of computers to many adolescents and the paucity of research on social-psychological effects of this technology. A content analysis based on a total sample of 10,224 words was performed using the Harvard IV Psychosociological Dictionary. Results indicated that computer-mediated communication was more expressive of feelings and made more frequent mention of interpersonal issues. Further, it displayed a more positive object-relations stance, was less negative in expressive style, and appeared to diminish certain traditional gender differences in group communication. These findings suggest that the computer may have an interesting adjunct role to play in reducing communication deficits commonly observed in severely disturbed adolescent clinical populations.

The effect of computer-mediated social support in online communities on patient empowerment and doctor-patient communication.

PubMed

Oh, Hyun Jung; Lee, Byoungkwan

2012-01-01

In the context of diabetes, this study tested a mechanism through which Korean diabetes patients' exchange of computer-mediated social support (CMSS) in diabetes online communities influences their sense of empowerment and intention to actively communicate with the doctor. Analysis of data from 464 Korean diabetes patients indicates significant relationships among diabetes patients' online community activities, perceived CMSS, sense of empowerment, and their intention to actively communicate with the doctor. Diabetes patients who have engaged more in online community activities perceived greater social support from other members of the community. Perceived CMSS significantly predicted their intention to actively communicate with the doctor through sense of empowerment. Sense of empowerment was a valid underlying mechanism that explains how patients' perceived CMSS influences their intention to actively communicate with the doctor. The implications for health communication research and practice are discussed.

Assessing Group Interaction with Social Language Network Analysis

NASA Astrophysics Data System (ADS)

Scholand, Andrew J.; Tausczik, Yla R.; Pennebaker, James W.

In this paper we discuss a new methodology, social language network analysis (SLNA), that combines tools from social language processing and network analysis to assess socially situated working relationships within a group. Specifically, SLNA aims to identify and characterize the nature of working relationships by processing artifacts generated with computer-mediated communication systems, such as instant message texts or emails. Because social language processing is able to identify psychological, social, and emotional processes that individuals are not able to fully mask, social language network analysis can clarify and highlight complex interdependencies between group members, even when these relationships are latent or unrecognized.

Emoticons in computer-mediated communication: social motives and social context.

PubMed

Derks, Daantje; Bos, Arjan E R; von Grumbkow, Jasper

2008-02-01

This study investigated the role of emoticons in computer-mediated communication (CMC). The study consisted of an online questionnaire about the social motives for emoticon use and an experimental part in which participants (N = 1,251) had to respond to short Internet chats. In these chats, the interaction partner (friend vs. stranger) and the valence of the context (positive vs. negative) were manipulated. Results showed that emoticons are mostly used to express emotion, to strengthen a message, and to express humor. Furthermore, more emoticons were used in communication with friends than in communication with strangers, and more emoticons were used in a positive context than in a negative context. Participants seem to use emoticons in a way similar to facial behavior in face-to-face communication with respect to social context and interaction partner.

Computer-mediated communication and interpersonal attraction: an experimental test of two explanatory hypotheses.

PubMed

Antheunis, Marjolijn L; Valkenburg, Patti M; Peter, Jochen

2007-12-01

The aims of this study were (a) to investigate the influence of computer-mediated communication (CMC) on interpersonal attraction and (b) to examine two underlying processes in the CMC-interpersonal attraction relationship. We identified two variables that may mediate the influence of CMC on interpersonal attraction: self-disclosure and direct questioning. Focusing on these potential mediating variables, we tested two explanatory hypotheses: the CMC-induced direct questioning hypothesis and the CMC-induced self-disclosure hypothesis. Eighty-one cross-sex dyads were randomly assigned to one of three experimental conditions: text-only CMC, visual CMC, and face-to-face communication. We did not find a direct effect of CMC on interpersonal attraction. However, we did find two positive indirect effects of text-only CMC on interpersonal attraction: text-only CMC stimulated both self-disclosure and direct questioning, both of which in turn enhanced interpersonal attraction. Results are discussed in light of uncertainty reduction theory and CMC theories.

A filter-mediated communication model for design collaboration in building construction.

PubMed

Lee, Jaewook; Jeong, Yongwook; Oh, Minho; Hong, Seung Wan

2014-01-01

Multidisciplinary collaboration is an important aspect of modern engineering activities, arising from the growing complexity of artifacts whose design and construction require knowledge and skills that exceed the capacities of any one professional. However, current collaboration in the architecture, engineering, and construction industries often fails due to lack of shared understanding between different participants and limitations of their supporting tools. To achieve a high level of shared understanding, this study proposes a filter-mediated communication model. In the proposed model, participants retain their own data in the form most appropriate for their needs with domain-specific filters that transform the neutral representations into semantically rich ones, as needed by the participants. Conversely, the filters can translate semantically rich, domain-specific data into a neutral representation that can be accessed by other domain-specific filters. To validate the feasibility of the proposed model, we computationally implement the filter mechanism and apply it to a hypothetical test case. The result acknowledges that the filter mechanism can let the participants know ahead of time what will be the implications of their proposed actions, as seen from other participants' points of view.

Lindblom, Katrina; Gregory, Tess; Flight, Ingrid H K; Zajac, Ian

2011-01-01

Objective This study investigated the efficacy of an internet-based personalized decision support (PDS) tool designed to aid in the decision to screen for colorectal cancer (CRC) using a fecal occult blood test. We tested whether the efficacy of the tool in influencing attitudes to screening was mediated by perceived usability and acceptability, and considered the role of computer self-efficacy and computer anxiety in these relationships. Methods Eighty-one participants aged 50–76 years worked through the on-line PDS tool and completed questionnaires on computer self-efficacy, computer anxiety, attitudes to and beliefs about CRC screening before and after exposure to the PDS, and perceived usability and acceptability of the tool. Results Repeated measures ANOVA found that PDS exposure led to a significant increase in knowledge about CRC and screening, and more positive attitudes to CRC screening as measured by factors from the Preventive Health Model. Perceived usability and acceptability of the PDS mediated changes in attitudes toward CRC screening (but not CRC knowledge), and computer self-efficacy and computer anxiety were significant predictors of individuals' perceptions of the tool. Conclusion Interventions designed to decrease computer anxiety, such as computer courses and internet training, may improve the acceptability of new health information technologies including internet-based decision support tools, increasing their impact on behavior change.

Yang, Christopher C

2012-01-01

Background Expressing emotion in online support communities is an important aspect of enabling e-patients to connect with each other and expand their social resources. Indirectly it increases the amount of support for coping with health issues. Exploring the supportive interaction patterns in online health social networking would help us better understand how technology features impacts user behavior in this context. Objective To build on previous research that identified different types of social support in online support communities by delving into patterns of supportive behavior across multiple computer-mediated communication formats. Each format combines different architectural elements, affecting the resulting social spaces. Our research question compared communication across different formats of text-based computer-mediated communication provided on the MedHelp.org health social networking environment. Methods We identified messages with nurturant support (emotional, esteem, and network) across three different computer-mediated communication formats (forums, journals, and notes) of an online support community for alcoholism using content analysis. Our sample consisted of 493 forum messages, 423 journal messages, and 1180 notes. Results Nurturant support types occurred frequently among messages offering support (forum comments: 276/412 messages, 67.0%; journal posts: 65/88 messages, 74%; journal comments: 275/335 messages, 82.1%; and notes: 1002/1180 messages, 84.92%), but less often among messages requesting support. Of all the nurturing supports, emotional (ie, encouragement) appeared most frequently, with network and esteem support appearing in patterns of varying combinations. Members of the Alcoholism Community appeared to adapt some traditional face-to-face forms of support to their needs in becoming sober, such as provision of encouragement, understanding, and empathy to one another. Conclusions The computer-mediated communication format may have the greatest influence on the supportive interactions because of characteristics such as audience reach and access. Other factors include perception of community versus personal space or purpose of communication. These results lead to a need for further research. PMID:22555303

Does the medium matter? The interaction of task type and technology on group performance and member reactions.

PubMed

Straus, S G; McGrath, J E

1994-02-01

The authors investigated the hypothesis that as group tasks pose greater requirements for member interdependence, communication media that transmit more social context cues will foster group performance and satisfaction. Seventy-two 3-person groups of undergraduate students worked in either computer-mediated or face-to-face meetings on 3 tasks with increasing levels of interdependence: an idea-generation task, an intellective task, and a judgment task. Results showed few differences between computer-mediated and face-to-face groups in the quality of the work completed but large differences in productivity favoring face-to-face groups. Analysis of productivity and of members' reactions supported the predicted interaction of tasks and media, with greater discrepancies between media conditions for tasks requiring higher levels of coordination. Results are discussed in terms of the implications of using computer-mediated communications systems for group work.

Boyle, Andrea M; O'Sullivan, Lucia F

2016-05-01

Little is known about the features, depth, and quality of communication in heterosexual dating relationships that include computer-mediated communication (CMC). This study examined these features as well as CMC's potential to facilitate self-disclosure and information-seeking. It also evaluated whether partner CMC interactions play a role in partner intimacy and communication quality. Young adults (N = 359; 18-24) attending postsecondary education institutions completed an online survey about their CMC use. To be included in the study, all participants were in established dating relationships at the time of the study and reported daily communication with their partner. CMC was linked to partners' disclosure of nonintimate information. This personal self-disclosure was linked positively to relationship intimacy and communication quality, beyond contributions from face-to-face interactions. Breadth (not depth) of self-disclosure and positively valenced interactions, in particular, proved key to understanding greater levels of intimacy in dating relationships and better communication quality as a function of CMC. CMC provides opportunities for partners to stay connected and to improve the overall quality of their intimacy and communication.

SNAD: Sequence Name Annotation-based Designer.

PubMed

Sidorov, Igor A; Reshetov, Denis A; Gorbalenya, Alexander E

2009-08-14

A growing diversity of biological data is tagged with unique identifiers (UIDs) associated with polynucleotides and proteins to ensure efficient computer-mediated data storage, maintenance, and processing. These identifiers, which are not informative for most people, are often substituted by biologically meaningful names in various presentations to facilitate utilization and dissemination of sequence-based knowledge. This substitution is commonly done manually that may be a tedious exercise prone to mistakes and omissions. Here we introduce SNAD (Sequence Name Annotation-based Designer) that mediates automatic conversion of sequence UIDs (associated with multiple alignment or phylogenetic tree, or supplied as plain text list) into biologically meaningful names and acronyms. This conversion is directed by precompiled or user-defined templates that exploit wealth of annotation available in cognate entries of external databases. Using examples, we demonstrate how this tool can be used to generate names for practical purposes, particularly in virology. A tool for controllable annotation-based conversion of sequence UIDs into biologically meaningful names and acronyms has been developed and placed into service, fostering links between quality of sequence annotation, and efficiency of communication and knowledge dissemination among researchers.

Awareness in the Home: The Nuances of Relationships, Domestic Coordination and Communication

NASA Astrophysics Data System (ADS)

Greenberg, Saul; Neustaedter, Carman; Elliot, Kathryn

Computing has changed dramatically over the last decade. While some changes arose from technological advances, the most profound effects are in how technologies are used by everyday people for activities other than task-oriented work. Computers are now central to new ways of engaging in play, interpersonal and small group communication, community interaction, entertainment, personal creativity dissemination, personal publication, and so on. We are particularly interested in domestic computing, where technology mediates how families and other inhabitants interact within the context of the home. While domestic computing can incorporate many things, we focus in this chapter on the role awareness plays in domestic coordination and communication.

To compare the experiences of women with metastatic breast cancer (MBC) in computer-mediated and face-to-face support groups. Interviews from 18 women with MBC, who were currently in computer-mediated support groups (CMSGs), were examined using interpretative phenomenological analysis. The CMSGs were in an asynchronous mailing list format; women communicated exclusively via email. All the women were also, or had previously been, in a face-to-face support group (FTFG). CMSGs had both advantages and drawbacks, relative to face-to-face groups (FTFGs), for this population. Themes examined included convenience, level of support, intimacy, ease of expression, range of information, and dealing with debilitation and dying. CMSGs may provide a sense of control and a greater level of support. Intimacy may take longer to develop in a CMSG, but women may have more opportunities to get to know each other. CMSGs may be helpful while adjusting to a diagnosis of MBC, because women can receive support without being overwhelmed by physical evidence of disability in others or exposure to discussions about dying before they are ready. However, the absence of nonverbal cues in CMSGs also led to avoidance of topics related to death and dying when women were ready to face them. Agendas for discussion, the presence of a facilitator or more time in CMSGs may attenuate this problem. The findings were discussed in light of prevailing research and theories about computer-mediated communication. They have implications for designing CMSGs for this population.

Life on the line: the therapeutic potentials of computer-mediated conversation.

Miller, J K; Gergen, K J

In what ways are computer networking practices comparable to face-to-face therapy? With the exponential increase in computer-mediated communication and the increasing numbers of people joining topically based computer networks, the potential for grass-roots therapeutic (or antitherapeutic) interchange is greatly augmented. Here we report the results of research into exchanges on an electronic bulletin board devoted to the topic of suicide. Over an 11-month period participants offered each other valuable resources in terms of validation of experience, sympathy, acceptance, and encouragement. They also asked provocative questions and furnished broad-ranging advice. Hostile entries were rare. However, there were few communiques that parallel the change-inducing practices more frequent within many therapeutic settings. In effect, on-line dialogues seemed more sustaining than transforming. Further limits and potentials of on-line communication are explored.

An Evolutionary Examination of Telemedicine: A Health and Computer-Mediated Communication Perspective

PubMed Central

Breen, Gerald-Mark; Matusitz, Jonathan

2009-01-01

Telemedicine, the use of advanced communication technologies in the healthcare context, has a rich history and a clear evolutionary course. In this paper, the authors identify telemedicine as operationally defined, the services and technologies it comprises, the direction telemedicine has taken, along with its increased acceptance in the healthcare communities. The authors also describe some of the key pitfalls warred with by researchers and activists to advance telemedicine to its full potential and lead to an unobstructed team of technicians to identify telemedicine’s diverse utilities. A discussion and future directions section is included to provide fresh ideas to health communication and computer-mediated scholars wishing to delve into this area and make a difference to enhance public understanding of this field.

Integrating on campus problem based learning and practice based learning: issues and challenges in using computer mediated communication.

PubMed

Conway, J; Sharkey, R

2002-10-01

The Faculty of Nursing, University of Newcastle, Australia, has been keen to initiate strategies that enhance student learning and nursing practice. Two strategies are problem based learning (PBL) and clinical practice. The Faculty has maintained a comparatively high proportion of the undergraduate hours in the clinical setting in times when financial constraints suggest that simulations and on campus laboratory experiences may be less expensive.Increasingly, computer based technologies are becoming sufficiently refined to support the exploration of nursing practice in a non-traditional lecture/tutorial environment. In 1998, a group of faculty members proposed that computer mediated instruction would provide an opportunity for partnership between students, academics and clinicians that would promote more positive outcomes for all and maintain the integrity of the PBL approach. This paper discusses the similarities between problem based and practice based learning and presents the findings of an evaluative study of the implementation of a practice based learning model that uses computer mediated communication to promote integration of practice experiences with the broader goals of the undergraduate curriculum.

The deterioration and deformation of a free-space optical beam wave-front as it propagates through the atmosphere can reduce the link availability and may introduce burst errors thus degrading the performance of the system. We investigate the suitability of utilizing soft-computing (SC) based tools for improving performance of free-space optical (FSO) communications systems. The SC based tools are used for the prediction of key parameters of a FSO communications system. Measured data collected from an experimental FSO communication system is used as training and testing data for a proposed multi-layer neural network predictor (MNNP) used to predict future parameter values. The predicted parameters are essential for reducing transmission errors by improving the antenna's accuracy of tracking data beams. This is particularly essential for periods considered to be of strong atmospheric turbulence. The parameter values predicted using the proposed tool show acceptable conformity with original measurements.

A Filter-Mediated Communication Model for Design Collaboration in Building Construction

PubMed Central

Oh, Minho

2014-01-01

Multidisciplinary collaboration is an important aspect of modern engineering activities, arising from the growing complexity of artifacts whose design and construction require knowledge and skills that exceed the capacities of any one professional. However, current collaboration in the architecture, engineering, and construction industries often fails due to lack of shared understanding between different participants and limitations of their supporting tools. To achieve a high level of shared understanding, this study proposes a filter-mediated communication model. In the proposed model, participants retain their own data in the form most appropriate for their needs with domain-specific filters that transform the neutral representations into semantically rich ones, as needed by the participants. Conversely, the filters can translate semantically rich, domain-specific data into a neutral representation that can be accessed by other domain-specific filters. To validate the feasibility of the proposed model, we computationally implement the filter mechanism and apply it to a hypothetical test case. The result acknowledges that the filter mechanism can let the participants know ahead of time what will be the implications of their proposed actions, as seen from other participants' points of view.

Will online chat help alleviate mood loneliness?

PubMed

Hu, Mu

2009-04-01

The present study examines the relationship between social Internet use and loneliness and reviews the studies about this topic from both social psychology and computer-mediated communication literature, as a response to the call for interdisciplinary research from scholars in these two areas. Two hundred thirty-four people participated in both the survey testing trait loneliness and a 5-condition (face-to-face chatting, instant message chatting, watching video, writing assignments, and "do nothing") experiment. Participants reported increase of mood loneliness after chatting online. The level of mood loneliness after online chat was higher than that in face-to-face communication. For people with high trait loneliness, the mood loneliness increase in the computer-mediated communication condition was significantly higher than in the face-to-face communication condition. The author of the current study hopes to help clarify the mixed research findings in previous social Internet use literature about this topic and reminds communication researchers of the need to explore the constructs included in "psychological well-being" in terms of their nature, mechanism, causes, consequences, and furthermore, how they are related to communication.

Interpreting and communicating water issues in an era of exponentially increasing information requires a blend of domain expertise, computational proficiency, and communication skills. The USGS Office of Water Information has established a Data Science team to meet these needs, providing challenging careers for diverse domain scientists and innovators in the fields of information technology and data visualization. Here, we detail the experience of building a Data Science capability as a bridging element between traditional water resources analyses and modern computing tools and data management techniques. This approach includes four major components: 1) building reusable research tools, 2) documenting data-intensive research approaches in peer reviewed journals, 3) communicating complex water resources issues with interactive web visualizations, and 4) offering training programs for our peers in scientific computing. These components collectively improve the efficiency, transparency, and reproducibility of USGS data analyses and scientific workflows.

Hot or cold: is communicating anger or threats more effective in negotiation?

Sinaceur, Marwan; Van Kleef, Gerben A; Neale, Margaret A; Adam, Hajo; Haag, Christophe

2011-09-01

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

Because of the use of human participants and differing contextual variables, research in second language acquisition often produces conflicting results, leaving practitioners confused and unsure of the effectiveness of specific treatments. This article provides insight into a recent seminal meta-analysis on the effectiveness of computer-mediated communication, providing further statistical evidence of the importance of its results. The significance of the study is examined by looking at the p values included in the references, to demonstrate how results can easily be misconstrued by practitioners and researchers. Lin's conclusion regarding the research setting of the study reports is also evaluated. In doing so, other possible explanations of what may be influencing the results can be proposed. © The Author(s) 2016.

Zummo, Marianna Lya

2015-01-01

This paper questions the nature of the communicative event that takes place in online contexts between doctors and web-users, showing computer-mediated linguistic norms and discussing the nature of the participants’ roles. Based on an analysis of 1005 posts occurring between doctors and the users of health service websites, I analyse how doctor–patient communication is affected by the medium and how health professionals overcome issues concerning the virtual medical visit. Results suggest that (a) online medical answers offer a different service from that expected by users, as doctors cannot always fulfill patient requests, and (b) net consultations use aspects of traditional doctor–patient exchange and yet present a language and a style that are affected by the computer-mediated environment. Additionally, it seems that this new form leads to a different model of doctor–patient relationship. The findings are intended to provide new insights into web-based discourse in doctor–patient communication and to demonstrate the emergence of a new style in medical communication.

Are shy adults really bolder online? It depends on the context.

PubMed

Brunet, Paul M; Schmidt, Louis A

2008-12-01

We examined whether individual differences in shyness and context influenced the amount of computer-mediated self-disclosure and use of affective language during an unfamiliar dyadic social interaction. Unfamiliar young adults were selected for high and low self-reported shyness and paired in mixed dyads (one shy and one nonshy). Each dyad was randomly assigned to either a live webcam or no webcam condition. Participants then engaged in a 20-minute online free chat over the Internet in the laboratory. Free chat conversations were archived, and the transcripts were objectively coded for traditional communication variables, conversational style, and the use of affective language. As predicted, shy adults engaged in significantly fewer spontaneous self-disclosures than did their nonshy counterparts only in the webcam condition. Shy versus nonshy adults did not differ on spontaneous self-disclosures in the no webcam condition. However, context did not influence the use of computer-mediated affective language. Although shy adults used significantly less active and pleasant words than their nonshy counterparts, these differences were not related to webcam condition. The present findings replicate and extend earlier work on shyness, context, and computer-mediated communication to a selected sample of shy adults. Findings suggest that context may influence some, but not all, aspects of social communication in shy adults.

The influence of multiple trials and computer-mediated communication on collaborative and individual semantic recall.

PubMed

Hinds, Joanne M; Payne, Stephen J

2018-04-01

Collaborative inhibition is a phenomenon where collaborating groups experience a decrement in recall when interacting with others. Despite this, collaboration has been found to improve subsequent individual recall. We explore these effects in semantic recall, which is seldom studied in collaborative retrieval. We also examine "parallel CMC", a synchronous form of computer-mediated communication that has previously been found to improve collaborative recall [Hinds, J. M., & Payne, S. J. (2016). Collaborative inhibition and semantic recall: Improving collaboration through computer-mediated communication. Applied Cognitive Psychology, 30(4), 554-565]. Sixty three triads completed a semantic recall task, which involved generating words beginning with "PO" or "HE" across three recall trials, in one of three retrieval conditions: Individual-Individual-Individual (III), Face-to-face-Face-to-Face-Individual (FFI) and Parallel-Parallel-Individual (PPI). Collaborative inhibition was present across both collaborative conditions. Individual recall in Recall 3 was higher when participants had previously collaborated in comparison to recalling three times individually. There was no difference between face-to-face and parallel CMC recall, however subsidiary analyses of instance repetitions and subjective organisation highlighted differences in group members' approaches to recall in terms of organisation and attention to others' contributions. We discuss the implications of these findings in relation to retrieval strategy disruption.

McLean, Michelle; Murrell, Kathy

2002-03-01

WebCT, front-end software for Internet-delivered material, became an integral part of a problem-based learning, student-centred curriculum introduced in January 2001 at the Nelson R. Mandela School of Medicine (South Africa). A template for six curriculum and two supplementary modules was developed. Organiser and Tool pages were added and files uploaded as each module progressed. This study provides feedback from students with regard to the value of WebCT in their curriculum, as well as discussing the value of WebCT for the delivery of digitized material (e.g., images, videos, PowerPoint presentations). In an anonymous survey following the completion of the first module, students, apparently irrespective of their level of computer literacy, responded positively to the communication facility between staff and students and amongst students, the resources and the URLs. Based on these preliminary responses, WebCT courses for all six modules were developed during 2001. With Faculty support, WebCT will probably be integrated into the rest of the MBChB programme. It will be particularly useful when students are off campus, undertaking electives and community service in the later years.

Psychological underpinnings of intrafamilial computer-mediated communication: a preliminary exploration of CMC uptake with parents and siblings.

PubMed

Goby, Valerie Priscilla

2011-06-01

This preliminary study investigates the uptake of computer-mediated communication (CMC) with parents and siblings, an area on which no research appears to have been conducted. Given the lack of relevant literature, grounded theory methodology was used and online focus group discussions were conducted in an attempt to generate suitable hypotheses for further empirical studies. Codification of the discussion data revealed various categories of meaning, namely: a perceived inappropriateness of CMC with members of family of origin; issues relating to the family generational gap; the nature of the offline sibling/parent relationship; the non-viability of online affordances such as planned self-disclosure, deception, identity construction; and disinhibition in interactions with family-of-origin members. These themes could be molded into hypotheses to assess the psychosocial limitations of CMC and to determine if it can indeed become a ubiquitous alternative to traditional communication modes as some scholars have claimed.

Communication and cooperation in networked environments: an experimental analysis.

PubMed

Galimberti, C; Ignazi, S; Vercesi, P; Riva, G

2001-02-01

Interpersonal communication and cooperation do not happen exclusively face to face. In work contexts, as in private life, there are more and more situations of mediated communication and cooperation in which new online tools are used. However, understanding how to use the Internet to support collaborative interaction presents a substantial challenge for the designers and users of this emerging technology. First, collaborative Internet environments are designed to serve a purpose, so must be designed with intended users' tasks and goals explicitly considered. Second, in cooperative activities the key content of communication is the interpretation of the situations in which actors are involved. So, the most effective way of clarifying the meaning of messages is to connect them to a shared context of meaning. However, this is more difficult in the Internet than in other computer-based activities. This paper tries to understand the characteristics of cooperative activities in networked environments--shared 3D virtual worlds--through two different studies. The first used the analysis of conversations to explore the characteristics of the interaction during the cooperative task; the second analyzed whether and how the level of immersion in the networked environments influenced the performance and the interactional process. The results are analyzed to identify the psychosocial roots used to support cooperation in a digital interactive communication.

A synthetic mammalian network to compute population borders based on engineered reciprocal cell-cell communication.

2015-12-30

Multicellular organisms depend on the exchange of information between specialized cells. This communication is often difficult to decipher in its native context, but synthetic biology provides tools to engineer well-defined systems that allow the convenient study and manipulation of intercellular communication networks. Here, we present the first mammalian synthetic network for reciprocal cell-cell communication to compute the border between a sender/receiver and a processing cell population. The two populations communicate via L-tryptophan and interleukin-4 to highlight the population border by the production of a fluorescent protein. The sharpness of that visualized edge can be adjusted by modulating key parameters of the network. We anticipate that this network will on the one hand be a useful tool to gain deeper insights into the mechanisms of tissue formation in nature and will on the other hand contribute to our ability to engineer artificial tissues.

Decision Accuracy in Computer-Mediated versus Face-to-Face Decision-Making Teams.

PubMed

Hedlund; Ilgen; Hollenbeck

1998-10-01

Changes in the way organizations are structured and advances in communication technologies are two factors that have altered the conditions under which group decisions are made. Decisions are increasingly made by teams that have a hierarchical structure and whose members have different areas of expertise. In addition, many decisions are no longer made via strictly face-to-face interaction. The present study examines the effects of two modes of communication (face-to-face or computer-mediated) on the accuracy of teams' decisions. The teams are characterized by a hierarchical structure and their members differ in expertise consistent with the framework outlined in the Multilevel Theory of team decision making presented by Hollenbeck, Ilgen, Sego, Hedlund, Major, and Phillips (1995). Sixty-four four-person teams worked for 3 h on a computer simulation interacting either face-to-face (FtF) or over a computer network. The communication mode had mixed effects on team processes in that members of FtF teams were better informed and made recommendations that were more predictive of the correct team decision, but leaders of CM teams were better able to differentiate staff members on the quality of their decisions. Controlling for the negative impact of FtF communication on staff member differentiation increased the beneficial effect of the FtF mode on overall decision making accuracy.

Talk or text to tell? How young adults in Canada and South Africa prefer to receive STI results, counseling, and treatment updates in a wireless world.

PubMed

Labacher, Lukas; Mitchell, Claudia

2013-01-01

Young adults often lack access to confidential, long-lasting, and nonjudgmental interactions with sexual health professionals at brick-and-mortar clinics. To ensure that patients return for their STI test results, post-result counseling, and STI-related information, computer-mediated health intervention programming allows them to receive sexual health information through onsite computers, the Internet, and mobile phone calls and text messages. To determine whether young adults (age: M = 21 years) prefer to communicate with health professionals about the status of their sexual health through computer-mediated communication devices, 303 second-year university students (183 from an urban North American university and 120 from a periurban university in South Africa) completed a paper-based survey indicating how they prefer to communicate with doctors and nurses: talking face to face, mobile phone call, text message, Internet chat programs, Facebook, Twitter, or e-mail. Nearly all students, and female students in South Africa in particular, prefer to receive their STI test results, post-results counseling, and STI-related information by talking face to face with doctors and nurses rather than communicating through computers or mobile phones. Results are clarified in relation to gender, availability of various technologies, and prevalence of HIV in Canada and in South Africa.

Mediation Training for the Physician: Expanding the Communication Toolkit to Manage Conflict.

PubMed

Kayser, Joshua B

2015-01-01

Good communication is critical to the practice of medicine. This is particularly true when outcomes are unpredictable and/or patients lack the capacity to participate in medical decision making. Disputes may develop that cannot be addressed using basic communication skills. Conflict of this nature can burden patients, families, and medical staff and may result in increased suffering for all parties. Many physicians lack the necessary communication tools to handle difficult conversations. Training in bioethics mediation provides physicians with skills that can promote healing by empowering participants to engage in effective discourse and break down barriers to find common ground. Mediation training for physicians can expand their capacity to connect with patients and enhance their ability to identify potential conflict early on, in order to collaborate more effectively. Competency in the processes of negotiation and conflict resolution should therefore be seen as essential elements of medical training. Copyright 2015 The Journal of Clinical Ethics.

An Integrated Review of Emoticons in Computer-Mediated Communication.

PubMed

Aldunate, Nerea; González-Ibáñez, Roberto

2016-01-01

Facial expressions constitute a rich source of non-verbal cues in face-to-face communication. They provide interlocutors with resources to express and interpret verbal messages, which may affect their cognitive and emotional processing. Contrarily, computer-mediated communication (CMC), particularly text-based communication, is limited to the use of symbols to convey a message, where facial expressions cannot be transmitted naturally. In this scenario, people use emoticons as paralinguistic cues to convey emotional meaning. Research has shown that emoticons contribute to a greater social presence as a result of the enrichment of text-based communication channels. Additionally, emoticons constitute a valuable resource for language comprehension by providing expressivity to text messages. The latter findings have been supported by studies in neuroscience showing that particular brain regions involved in emotional processing are also activated when people are exposed to emoticons. To reach an integrated understanding of the influence of emoticons in human communication on both socio-cognitive and neural levels, we review the literature on emoticons in three different areas. First, we present relevant literature on emoticons in CMC. Second, we study the influence of emoticons in language comprehension. Finally, we show the incipient research in neuroscience on this topic. This mini review reveals that, while there are plenty of studies on the influence of emoticons in communication from a social psychology perspective, little is known about the neurocognitive basis of the effects of emoticons on communication dynamics.

Wu, M.Y.; Gajski, D.D.

1989-12-01

As the number of processors and the complexity of problems to be solved increase, programming multiprocessing systems becomes more difficult and error-prone. Program development tools are necessary since programmers are not able to develop complex parallel programs efficiently. Parallel models of computation, parallelization problems, and tools for computer-aided programming (CAP) are discussed. As an example, a CAP tool that performs scheduling and inserts communication primitives automatically is described. It also generates the performance estimates and other program quality measures to help programmers in improving their algorithms and programs.

Visual analysis of inter-process communication for large-scale parallel computing.

PubMed

Muelder, Chris; Gygi, Francois; Ma, Kwan-Liu

2009-01-01

In serial computation, program profiling is often helpful for optimization of key sections of code. When moving to parallel computation, not only does the code execution need to be considered but also communication between the different processes which can induce delays that are detrimental to performance. As the number of processes increases, so does the impact of the communication delays on performance. For large-scale parallel applications, it is critical to understand how the communication impacts performance in order to make the code more efficient. There are several tools available for visualizing program execution and communications on parallel systems. These tools generally provide either views which statistically summarize the entire program execution or process-centric views. However, process-centric visualizations do not scale well as the number of processes gets very large. In particular, the most common representation of parallel processes is a Gantt char t with a row for each process. As the number of processes increases, these charts can become difficult to work with and can even exceed screen resolution. We propose a new visualization approach that affords more scalability and then demonstrate it on systems running with up to 16,384 processes.

Mediated learning in the workplace: student perspectives on knowledge resources.

PubMed

Shanahan, Madeleine

2015-01-01

In contemporary clinical practice, student radiographers can use many types of knowledge resources to support their learning. These include workplace experts, digital and nondigital information sources (eg, journals, textbooks, and the Internet), and electronic communication tools such as e-mail and social media. Despite the range of knowledge tools available, there is little available data about radiography students' use of these resources during clinical placement. A 68-item questionnaire was distributed to 62 students enrolled in an Australian university undergraduate radiography program after they completed a clinical placement. Researchers used descriptive statistics to analyze student access to workplace experts and their use of digital and nondigital information sources and electronic communication tools. A 5-point Likert scale (1 = very important; 5 = not important) was used to assess the present importance and perceived future value of knowledge tools for workplace learning. Of the 53 students who completed and returned the questionnaire anonymously, most rely on the knowledge of practicing technologists and on print and electronic information sources to support their learning; some students also use electronic communication tools. Students perceive that these knowledge resources also will be important tools for their future learning as qualified health professionals. The findings from this study present baseline data regarding the value students attribute to multiple knowledge tools and regarding student access to and use of these tools during clinical placement. In addition, most students have access to multiple knowledge tools in the workplace and incorporate these tools simultaneously into their overall learning practice during clinical placement. Although a range of knowledge tools is used in the workplace to support learning among student radiographers, the quality of each tool should be critically analyzed before it is adopted in practice. Integrating practice-based learning with learning mediated by information sources provides a more complete paradigm of learning during clinical placement.

Representation-based user interfaces for the audiovisual library of the year 2000

Aigrain, Philippe; Joly, Philippe; Lepain, Philippe; Longueville, Veronique

The audiovisual library of the future will be based on computerized access to digitized documents. In this communication, we address the user interface issues which will arise from this new situation. One cannot simply transfer a user interface designed for the piece by piece production of some audiovisual presentation and make it a tool for accessing full-length movies in an electronic library. One cannot take a digital sound editing tool and propose it as a means to listen to a musical recording. In our opinion, when computers are used as mediations to existing contents, document representation-based user interfaces are needed. With such user interfaces, a structured visual representation of the document contents is presented to the user, who can then manipulate it to control perception and analysis of these contents. In order to build such manipulable visual representations of audiovisual documents, one needs to automatically extract structural information from the documents contents. In this communication, we describe possible visual interfaces for various temporal media, and we propose methods for the economically feasible large scale processing of documents. The work presented is sponsored by the Bibliotheque Nationale de France: it is part of the program aiming at developing for image and sound documents an experimental counterpart to the digitized text reading workstation of this library.

A study of computer graphics technology in application of communication resource management

Li, Jing; Zhou, Liang; Yang, Fei

2017-08-01

With the development of computer technology, computer graphics technology has been widely used. Especially, the success of object-oriented technology and multimedia technology promotes the development of graphics technology in the computer software system. Therefore, the computer graphics theory and application technology have become an important topic in the field of computer, while the computer graphics technology becomes more and more extensive in various fields of application. In recent years, with the development of social economy, especially the rapid development of information technology, the traditional way of communication resource management cannot effectively meet the needs of resource management. In this case, the current communication resource management is still using the original management tools and management methods, resource management equipment management and maintenance, which brought a lot of problems. It is very difficult for non-professionals to understand the equipment and the situation in communication resource management. Resource utilization is relatively low, and managers cannot quickly and accurately understand the resource conditions. Aimed at the above problems, this paper proposes to introduce computer graphics technology into the communication resource management. The introduction of computer graphics not only makes communication resource management more vivid, but also reduces the cost of resource management and improves work efficiency.

The Challenges and Benefits of Using Computer Technology for Communication and Teaching in the Geosciences

Fairley, J. P.; Hinds, J. J.

2003-12-01

The advent of the World Wide Web in the early 1990s not only revolutionized the exchange of ideas and information within the scientific community, but also provided educators with a new array of teaching, informational, and promotional tools. Use of computer graphics and animation to explain concepts and processes can stimulate classroom participation and student interest in the geosciences, which has historically attracted students with strong spatial and visualization skills. In today's job market, graduates are expected to have knowledge of computers and the ability to use them for acquiring, processing, and visually analyzing data. Furthermore, in addition to promoting visibility and communication within the scientific community, computer graphics and the Internet can be informative and educational for the general public. Although computer skills are crucial for earth science students and educators, many pitfalls exist in implementing computer technology and web-based resources into research and classroom activities. Learning to use these new tools effectively requires a significant time commitment and careful attention to the source and reliability of the data presented. Furthermore, educators have a responsibility to ensure that students and the public understand the assumptions and limitations of the materials presented, rather than allowing them to be overwhelmed by "gee-whiz" aspects of the technology. We present three examples of computer technology in the earth sciences classroom: 1) a computer animation of water table response to well pumping, 2) a 3-D fly-through animation of a fault controlled valley, and 3) a virtual field trip for an introductory geology class. These examples demonstrate some of the challenges and benefits of these new tools, and encourage educators to expand the responsible use of computer technology for teaching and communicating scientific results to the general public.

Visualization and Interaction in Research, Teaching, and Scientific Communication

NASA Astrophysics Data System (ADS)

Ammon, C. J.

2017-12-01

Modern computing provides many tools for exploring observations, numerical calculations, and theoretical relationships. The number of options is, in fact, almost overwhelming. But the choices provide those with modest programming skills opportunities to create unique views of scientific information and to develop deeper insights into their data, their computations, and the underlying theoretical data-model relationships. I present simple examples of using animation and human-computer interaction to explore scientific data and scientific-analysis approaches. I illustrate how valuable a little programming ability can free scientists from the constraints of existing tools and can facilitate the development of deeper appreciation data and models. I present examples from a suite of programming languages ranging from C to JavaScript including the Wolfram Language. JavaScript is valuable for sharing tools and insight (hopefully) with others because it is integrated into one of the most powerful communication tools in human history, the web browser. Although too much of that power is often spent on distracting advertisements, the underlying computation and graphics engines are efficient, flexible, and almost universally available in desktop and mobile computing platforms. Many are working to fulfill the browser's potential to become the most effective tool for interactive study. Open-source frameworks for visualizing everything from algorithms to data are available, but advance rapidly. One strategy for dealing with swiftly changing tools is to adopt common, open data formats that are easily adapted (often by framework or tool developers). I illustrate the use of animation and interaction in research and teaching with examples from earthquake seismology.

An Integrated Review of Emoticons in Computer-Mediated Communication

PubMed Central

Aldunate, Nerea; González-Ibáñez, Roberto

2017-01-01

Facial expressions constitute a rich source of non-verbal cues in face-to-face communication. They provide interlocutors with resources to express and interpret verbal messages, which may affect their cognitive and emotional processing. Contrarily, computer-mediated communication (CMC), particularly text-based communication, is limited to the use of symbols to convey a message, where facial expressions cannot be transmitted naturally. In this scenario, people use emoticons as paralinguistic cues to convey emotional meaning. Research has shown that emoticons contribute to a greater social presence as a result of the enrichment of text-based communication channels. Additionally, emoticons constitute a valuable resource for language comprehension by providing expressivity to text messages. The latter findings have been supported by studies in neuroscience showing that particular brain regions involved in emotional processing are also activated when people are exposed to emoticons. To reach an integrated understanding of the influence of emoticons in human communication on both socio-cognitive and neural levels, we review the literature on emoticons in three different areas. First, we present relevant literature on emoticons in CMC. Second, we study the influence of emoticons in language comprehension. Finally, we show the incipient research in neuroscience on this topic. This mini review reveals that, while there are plenty of studies on the influence of emoticons in communication from a social psychology perspective, little is known about the neurocognitive basis of the effects of emoticons on communication dynamics.

Measurement of information and communication technology experience and attitudes to e-learning of students in the healthcare professions: integrative review.

PubMed

Wilkinson, Ann; While, Alison E; Roberts, Julia

2009-04-01

This paper is a report of a review to describe and discuss the psychometric properties of instruments used in healthcare education settings measuring experience and attitudes of healthcare students regarding their information and communication technology skills and their use of computers and the Internet for education. Healthcare professionals are expected to be computer and information literate at registration. A previous review of evaluative studies of computer-based learning suggests that methods of measuring learners' attitudes to computers and computer aided learning are problematic. A search of eight health and social science databases located 49 papers, the majority published between 1995 and January 2007, focusing on the experience and attitudes of students in the healthcare professions towards computers and e-learning. An integrative approach was adopted, with narrative description of findings. Criteria for inclusion were quantitative studies using survey tools with samples of healthcare students and concerning computer and information literacy skills, access to computers, experience with computers and use of computers and the Internet for education purposes. Since the 1980s a number of instruments have been developed, mostly in the United States of America, to measure attitudes to computers, anxiety about computer use, information and communication technology skills, satisfaction and more recently attitudes to the Internet and computers for education. The psychometric properties are poorly described. Advances in computers and technology mean that many earlier tools are no longer valid. Measures of the experience and attitudes of healthcare students to the increased use of e-learning require development in line with computer and technology advances.

The Effect of Health Beliefs, Media Perceptions, and Communicative Behaviors on Health Behavioral Intention: An Integrated Health Campaign Model on Social Media.

PubMed

Yoo, Sun-Wook; Kim, Jarim; Lee, Yeunjae

2018-01-01

Social media have recently gained attention as a potential health campaign tool. This study examines this line of expectation concerning the role social media may play in health campaigns by testing an integrated health campaign model that combines insights from research on social media-specific perceptions and communicative behaviors in order to predict health behaviors. Specifically, this study aims to (a) develop a more holistic social media campaign model for predicting health behaviors in the social media context, (b) investigate how social media channel-related perceptions affect preventive health behaviors, and (c) investigate how communicative behaviors mediate perceptions and behavioral intention. The study conducted an online survey of 498 females who followed the Purple Ribbon Twitter campaign (@pprb), a cervical cancer prevention campaign. The results indicated that information acquisition mediated perceived risk's effect on intention. Information acquisition also mediated the relationships between intention and information selection and information transmission. On the other hand, social media-related perceptions indirectly impacted behavioral intention through communicative behaviors. The findings' theoretical and practical implications are discussed.

This is the third in a series of columns exploring health information technology (HIT) in the neonatal intensive care unit (NICU). The first column provided background information on the implementation of information technology throughout the health care delivery system, as well as the requisite informatics competencies needed for nurses to fully engage in the digital era of health care. The second column focused on information and resources to master basic computer competencies described by the TIGER initiative (Technology Informatics Guiding Education Reform) as learning about computers, computer networks, and the transfer of data.1 This column will provide additional information related to basic computer competencies, focusing on communication and collaboration technologies. Computers and the Internet have transformed the way we communicate and collaborate. Electronic communication is the ability to exchange information through the use of computer equipment and software.2 Broadly defined, any technology that facilitates linking one or more individuals together is a collaborative tool. Collaboration using technology encompasses an extensive range of applications that enable groups of individuals to work together including e-mail, instant messaging (IM ), and several web applications collectively referred to as Web 2.0 technologies. The term Web 2.0 refers to web applications where users interact and collaborate with each other in a collective exchange of ideas generating content in a virtual community. Examples of Web 2.0 technologies include social networking sites, blogs, wikis, video sharing sites, and mashups. Many organizations are developing collaborative strategies and tools for employees to connect and interact using web-based social media technologies.3.

Technology addiction's contribution to mental wellbeing: The positive effect of online social capital.

PubMed

Magsamen-Conrad, Kate; Billotte-Verhoff, China; Greene, Kathryn

2014-11-01

This research examines the effect of online social capital and Internet use on the normally negative effects of technology addiction, especially for individuals prone to self-concealment. Self-concealment is a personality trait that describes individuals who are more likely to withhold personal and private information, inhibiting catharsis and wellbeing. Addiction, in any context, is also typically associated with negative outcomes. However, we investigate the hypothesis that communication technology addiction may positively affect wellbeing for self-concealing individuals when online interaction is positive, builds relationships, or fosters a sense of community. Within these parameters, increased communication through mediated channels (and even addiction) may reverse the otherwise negative effects of self-concealment on wellbeing. Overall, the proposed model offers qualified support for the continued analysis of mediated communication as a potential source for improving the wellbeing for particular individuals. This study is important because we know that healthy communication in relationships, including disclosure, is important to wellbeing. This study recognizes that not all people are comfortable communicating in face-to-face settings. Our findings offer evidence that the presence of computers in human behaviors (e.g., mediated channels of communication and NCTs) enables some individuals to communicate and fos ter beneficial interpersonal relationships, and improve their wellbeing.

2016-06-01

The borehole azimuthal acoustic reflection imaging logging tool (BAAR) is a new generation of imaging logging tool, which is able to investigate stratums in a relatively larger range of space around the borehole. The BAAR is designed based on the idea of modularization with a very complex structure, so it has become urgent for us to develop a dedicated test-bench system to debug each module of the BAAR. With the help of a test-bench system introduced in this paper, test and calibration of BAAR can be easily achieved. The test-bench system is designed based on the client/server model. The hardware system mainly consists of a host computer, an embedded controlling board, a bus interface board, a data acquisition board and a telemetry communication board. The host computer serves as the human machine interface and processes the uploaded data. The software running on the host computer is designed based on VC++. The embedded controlling board uses Advanced Reduced Instruction Set Machines 7 (ARM7) as the micro controller and communicates with the host computer via Ethernet. The software for the embedded controlling board is developed based on the operating system uClinux. The bus interface board, data acquisition board and telemetry communication board are designed based on a field programmable gate array (FPGA) and provide test interfaces for the logging tool. To examine the feasibility of the test-bench system, it was set up to perform a test on BAAR. By analyzing the test results, an unqualified channel of the electronic receiving cabin was discovered. It is suggested that the test-bench system can be used to quickly determine the working condition of sub modules of BAAR and it is of great significance in improving production efficiency and accelerating industrial production of the logging tool.

The Communication Analysis Tool for the Space Station (CATSS) is a FORTRAN language software package capable of predicting the communications links performance for the Space Station (SS) communication and tracking (C & T) system. An interactive software package was currently developed to run on the DEC/VAX computers. The CATSS models and evaluates the various C & T links of the SS, which includes the modulation schemes such as Binary-Phase-Shift-Keying (BPSK), BPSK with Direct Sequence Spread Spectrum (PN/BPSK), and M-ary Frequency-Shift-Keying with Frequency Hopping (FH/MFSK). Optical Space Communication link is also included. CATSS is a C & T system engineering tool used to predict and analyze the system performance for different link environment. Identification of system weaknesses is achieved through evaluation of performance with varying system parameters. System tradeoff for different values of system parameters are made based on the performance prediction.

Helping Older Adults Improve Their Medication Experience (HOME) by Addressing Medication Regimen Complexity in Home Healthcare.

PubMed

Sheehan, Orla C; Kharrazi, Hadi; Carl, Kimberly J; Leff, Bruce; Wolff, Jennifer L; Roth, David L; Gabbard, Jennifer; Boyd, Cynthia M

In skilled home healthcare (SHHC), communication between nurses and physicians is often inadequate for medication reconciliation and needed changes to the medication regimens are rarely made. Fragmentation of electronic health record (EHR) systems, transitions of care, lack of physician-nurse in-person contact, and poor understanding of medications by patients and their families put patients at risk for serious adverse outcomes. The aim of this study was to develop and test the HOME tool, an informatics tool to improve communication about medication regimens, share the insights of home care nurses with physicians, and highlight to physicians and nurses the complexity of medication schedules. We used human computer interaction design and evaluation principles, automated extraction from standardized forms, and modification of existing EHR fields to highlight key medication-related insights that had arisen during the SHHC visit. Separate versions of the tool were developed for physicians/nurses and patients/caregivers. A pilot of the tool was conducted using 20 SHHC encounters. Home care nurses and physicians found the tool useful for communication. Home care nurses were able to implement the HOME tool into their clinical workflow and reported improved communication with physicians about medications. This simple and largely automated tool improves understanding and communication around medications in SHHC.

Auto-Generated Semantic Processing Services

Davis, Rodney; Hupf, Greg

2009-01-01

Auto-Generated Semantic Processing (AGSP) Services is a suite of software tools for automated generation of other computer programs, denoted cross-platform semantic adapters, that support interoperability of computer-based communication systems that utilize a variety of both new and legacy communication software running in a variety of operating- system/computer-hardware combinations. AGSP has numerous potential uses in military, space-exploration, and other government applications as well as in commercial telecommunications. The cross-platform semantic adapters take advantage of common features of computer- based communication systems to enforce semantics, messaging protocols, and standards of processing of streams of binary data to ensure integrity of data and consistency of meaning among interoperating systems. The auto-generation aspect of AGSP Services reduces development time and effort by emphasizing specification and minimizing implementation: In effect, the design, building, and debugging of software for effecting conversions among complex communication protocols, custom device mappings, and unique data-manipulation algorithms is replaced with metadata specifications that map to an abstract platform-independent communications model. AGSP Services is modular and has been shown to be easily integrable into new and legacy NASA flight and ground communication systems.

Human sensory and motor systems provide the natural means for the exchange of information between individuals, and, hence, the basis for human civilization. The recent development of brain-computer interfaces (BCI) has provided an important element for the creation of brain-to-brain communication systems, and precise brain stimulation techniques are now available for the realization of non-invasive computer-brain interfaces (CBI). These technologies, BCI and CBI, can be combined to realize the vision of non-invasive, computer-mediated brain-to-brain (B2B) communication between subjects (hyperinteraction). Here we demonstrate the conscious transmission of information between human brains through the intact scalp and without intervention of motor or peripheral sensory systems. Pseudo-random binary streams encoding words were transmitted between the minds of emitter and receiver subjects separated by great distances, representing the realization of the first human brain-to-brain interface. In a series of experiments, we established internet-mediated B2B communication by combining a BCI based on voluntary motor imagery-controlled electroencephalographic (EEG) changes with a CBI inducing the conscious perception of phosphenes (light flashes) through neuronavigated, robotized transcranial magnetic stimulation (TMS), with special care taken to block sensory (tactile, visual or auditory) cues. Our results provide a critical proof-of-principle demonstration for the development of conscious B2B communication technologies. More fully developed, related implementations will open new research venues in cognitive, social and clinical neuroscience and the scientific study of consciousness. We envision that hyperinteraction technologies will eventually have a profound impact on the social structure of our civilization and raise important ethical issues.

Over the years, various distance learning technologies and methods have been applied to the continuing medical education needs of rural and remote physicians. They have included audio teleconferencing, slow scan imaging, correspondence study, and compressed videoconferencing. The recent emergence and growth of Internet, World Wide Web (Web), and compact disk read-only-memory (CD-ROM) technologies have introduced new opportunities for providing continuing education to the rural medical practitioner. This evaluation study assessed the instructional effectiveness of a hybrid computer-mediated courseware delivery system on dermatologic office procedures. A hybrid delivery system merges Web documents, multimedia, computer-mediated communications, and CD-ROMs to enable self-paced instruction and collaborative learning. Using a modified pretest to post-test control group study design, several evaluative criteria (participant reaction, learning achievement, self-reported performance change, and instructional transactions) were assessed by various qualitative and quantitative data collection methods. This evaluation revealed that a hybrid computer-mediated courseware system was an effective means for increasing knowledge (p < .05) and improving self-reported competency (p < .05) in dermatologic office procedures, and that participants were very satisfied with the self-paced instruction and use of asynchronous computer conferencing for collaborative information sharing among colleagues.

Gallagher, Peter

2005-01-01

Over the past 20 years, focus groups have become increasingly popular with nursing researchers as a data collection method, as has the use of computer-based technologies to support all forms of nursing research. This article describes the conduct of a series of focus groups in which the participants were in the same room as part of a "real-time" discussion during which they also used personal computers as an interface between each other and the moderator. Synchronous Computer Mediated Group Discussion differed from other forms of focus group discussion in that participants used personal computers rather than verbal expressions to respond to specific questions, engage in communication with other participants, and to record their thoughts. This form of focus group maintained many of the features of spoken exchanges, a cornerstone of the focus group, while capturing the advantages of online discussion.

Learning experiences of science teachers in a computer-mediated communication context

NASA Astrophysics Data System (ADS)

Chung, Chia-Jung

The use of computer-mediated-communication (CMC) has been applied increasingly in staff development efforts for teachers. Many teacher education programs are looking to CMC, particularly computer conferencing systems, as an effective and low-cost medium for the delivery of teacher educational programs anytime, anywhere. Based on constructivist learning theories, this study focused on examining the use of an online discussion board in a graduate course as a place where forty-six inservice teachers shared experiences and ideas. Data collection focused on online discussion transcripts of all the messages from three separate weeks, and supplemented by interviews and teacher self-evaluation reports. The nature and development of the discussions were studied over one semester by analyzing teacher online discussions in two domains: critical reflections and social-interpersonal rapport. In effect, this study provided insights into how to employ computer conferencing technology in facilitating inservice teachers' teaching practices and their professional development. Major findings include: (1) Participation: The level of participation varied during the semester but was higher at the beginning of the semester and lower at the end of the semester. (2) Critical Reflection: Teachers' critical reflection developed over time as a result of the online discussion board according to mean critical thinking scores during the three selected weeks. Cognitive presence was found mostly in focused discussion forums and social presence mainly existed in the unfocused discussion forums. (3) Social-Interpersonal Rapport: The number of social cues in the messages increased initially but declined significantly over time. When teachers focused more on on-task discussions or critical reflection, there was less social conversation. (4) Teaching Practices and Professional Development: The researcher, the instructor, and teachers identified some advantages for using computer conferencing for improving teaching practices and for professional development. The results of this study suggest that applying computer-mediated communication in teacher education would impact positively on teachers' growth in critical reflection and social-interpersonal rapport. Furthermore, this study may encourage other researchers to use cognitive and social learning theories as the theoretical backgrounds for developing teacher educational models by applying computer conferencing.

Quantifiable and objective approach to organizational performance enhancement.

Scholand, Andrew Joseph; Tausczik, Yla R.

This report describes a new methodology, social language network analysis (SLNA), that combines tools from social language processing and network analysis to identify socially situated relationships between individuals which, though subtle, are highly influential. Specifically, SLNA aims to identify and characterize the nature of working relationships by processing artifacts generated with computer-mediated communication systems, such as instant message texts or emails. Because social language processing is able to identify psychological, social, and emotional processes that individuals are not able to fully mask, social language network analysis can clarify and highlight complex interdependencies between group members, even when these relationships aremore » latent or unrecognized. This report outlines the philosophical antecedents of SLNA, the mechanics of preprocessing, processing, and post-processing stages, and some example results obtained by applying this approach to a 15-month corporate discussion archive.« less

Quantum computation is a fast-growing, multi-disciplinary research field. The purpose of a quantum computer is to execute quantum algorithms that efficiently solve computational problems intractable within the existing paradigm of 'classical' computing built on bits and Boolean gates. While collaboration between computer scientists, physicists, chemists, engineers, mathematicians and others is essential to the project's success, traditional disciplinary boundaries can hinder progress and make communicating the aims of quantum computing and future technologies difficult. We have developed a four minute animation as a tool for representing, understanding and communicating a silicon-based solid-state quantum computer to a variety of audiences, either as a stand-alone animation to be used by expert presenters or embedded into a longer movie as short animated sequences. The paper includes a generally applicable recipe for successful scientific animation production.

A brain-computer interface for potential non-verbal facial communication based on EEG signals related to specific emotions

PubMed Central

Kashihara, Koji

2014-01-01

Unlike assistive technology for verbal communication, the brain-machine or brain-computer interface (BMI/BCI) has not been established as a non-verbal communication tool for amyotrophic lateral sclerosis (ALS) patients. Face-to-face communication enables access to rich emotional information, but individuals suffering from neurological disorders, such as ALS and autism, may not express their emotions or communicate their negative feelings. Although emotions may be inferred by looking at facial expressions, emotional prediction for neutral faces necessitates advanced judgment. The process that underlies brain neuronal responses to neutral faces and causes emotional changes remains unknown. To address this problem, therefore, this study attempted to decode conditioned emotional reactions to neutral face stimuli. This direction was motivated by the assumption that if electroencephalogram (EEG) signals can be used to detect patients' emotional responses to specific inexpressive faces, the results could be incorporated into the design and development of BMI/BCI-based non-verbal communication tools. To these ends, this study investigated how a neutral face associated with a negative emotion modulates rapid central responses in face processing and then identified cortical activities. The conditioned neutral face-triggered event-related potentials that originated from the posterior temporal lobe statistically significantly changed during late face processing (600–700 ms) after stimulus, rather than in early face processing activities, such as P1 and N170 responses. Source localization revealed that the conditioned neutral faces increased activity in the right fusiform gyrus (FG). This study also developed an efficient method for detecting implicit negative emotional responses to specific faces by using EEG signals. A classification method based on a support vector machine enables the easy classification of neutral faces that trigger specific individual emotions. In accordance with this classification, a face on a computer morphs into a sad or displeased countenance. The proposed method could be incorporated as a part of non-verbal communication tools to enable emotional expression. PMID:25206321

Shaarani, Issam; Taleb, Rim; Antoun, Jumana

2017-12-01

Physician-patient communication is essential in the physician-patient relationship. Concerns were raised about the impact of the computer on this relationship with the increase in use of electronic medical records (EMR). Most studies addressed the physician's perspective and only few explored the patient's perspective. This study aims to assess the patient's perspective of the effect of the physician's computer use during the clinical encounter on the interpersonal and communication skills of the physician using a validated communication assessment tool (CAT). This is a cross-sectional survey of three hundred eighty-two patients who visited the family medicine clinics (FMC) at the American University of Beirut Medical Center (AUBMC). At the end of the visit with the physician, the patients were approached by the clinical assistant to fill a paper-based questionnaire privately in the waiting room to measure communication skills of physicians using CAT. Nearly two-thirds of the patients (62%) did not consider that using the computer by their physician during the visit would negatively affect the patient-doctor communication. Patients rated their physician with a higher communication score when there was an ongoing relationship between the physician and the patient. Higher communication scores were reported for extensive use of the computer by the physician to check results (p<0.001), to retrieve patient record information (p<0.001) and to educate patients (p<0.001) as compared to less use. Physician-patient communication was not negatively affected by the physician use of the computer as rated by patients. An ongoing relationship with the physician remains a significant predictor of better physician-patient communication even in the presence of the computer. Copyright © 2017 Elsevier B.V.

The Design of Modular Web-Based Collaboration

NASA Astrophysics Data System (ADS)

Intapong, Ploypailin; Settapat, Sittapong; Kaewkamnerdpong, Boonserm; Achalakul, Tiranee

Online collaborative systems are popular communication channels as the systems allow people from various disciplines to interact and collaborate with ease. The systems provide communication tools and services that can be integrated on the web; consequently, the systems are more convenient to use and easier to install. Nevertheless, most of the currently available systems are designed according to some specific requirements and cannot be straightforwardly integrated into various applications. This paper provides the design of a new collaborative platform, which is component-based and re-configurable. The platform is called the Modular Web-based Collaboration (MWC). MWC shares the same concept as computer supported collaborative work (CSCW) and computer-supported collaborative learning (CSCL), but it provides configurable tools for online collaboration. Each tool module can be integrated into users' web applications freely and easily. This makes collaborative system flexible, adaptable and suitable for online collaboration.

An exploratory examination of the relationship between motivational factors and the degree to which the higher education faculty integrate computer-mediated communication (CMC) tools into their courses

NASA Astrophysics Data System (ADS)

Murage, Francis Ndwiga

The stated research problem of this study was to examine the relationship between motivational factors and the degree to which the higher education faculty integrate CMC tools into their courses. The study population and sample involved higher education faculty teaching in science departments at one public university and three public colleges in the state of West Virginia (N = 153). A Likert-type rating scale survey was used to collect data based on the research questions. Two parts of the survey were adopted from previous studies while the other two were self-constructed. Research questions and hypothesis were analyzed using both descriptive and inferential analyses. The study results established a positive relationship between motivational factors and the degree the higher education faculty integrate CMC tools in their courses. The results in addition established that faculty are highly motivated to integrate CMC tools by intrinsic factors, moderately motivated by environmental factors and least motivated by extrinsic factors. The results also established that the most integrated CMC tools were those that support asynchronous methods of communication while the least integrated were those that support synchronous methods of communication. A major conclusion made was that members of higher education faculty are more likely to be motivated to integrate CMC tools into their courses by intrinsic factors rather than extrinsic or environmental factors. It was further concluded that intrinsic factors that supported and enhanced student learning as well as those that were altruistic in nature significantly influenced the degree of CMC integration. The study finally concluded that to larger extent, there is a relationship between motivational factors and the degree to which the higher education faculty integrate CMC tools in their courses. A major implication of this study was that institutions that wish to promote integration of CMC technologies should provide as much evidence as possible that the new mode of teaching will improve learning and meet the teaching needs of individual faculty. Further, institutional leadership should recognize and consider individual differences among faculty, especially acknowledging that locus of motivation is not the same for everyone and that it changes overtime depending on internal and external factors.

Sexually explicit Internet chat rooms are increasingly used by pedophiles to reach potential victims. Logging and linking suspects to chat room conversations and e-mails exchanged with undercover detectives are crucial to prosecuting travelers, i.e., pedophiles who travel across state lines to engage in sexual acts with minors. This paper describes two tools, a chat room monitor and a remote fingerprinter, for acquiring and preserving evidence. The chat room monitor logs online communications as well as screen images and keystrokes of the undercover detective. stored to allow the chronological reconstruction and replay of the investigation. The remote fingerprinter uses sophisticated scanning techniques to capture and preserve a unique fingerprint of the suspect's computer over the Internet. Once the suspect's computer is seized, it is scanned again; matching this new fingerprint with the remotely acquired fingerprint establishes that the suspect's computer was used to communicate with the detective.

2016-12-01

The use of computer-mediated communication (CMC) as a form of social interaction has become increasingly prevalent, yet few studies examine individual differences that may shed light on implications of CMC for adjustment. The current study examined neurocognitive individual differences associated with preferences to use technology in relation to social-emotional outcomes. In Study 1 (N = 91), a self-report measure, the Social Media Communication Questionnaire (SMCQ), was evaluated as an assessment of preferences for communicating positive and negative emotions on a scale ranging from purely via CMC to purely face-to-face. In Study 2, SMCQ preferences were examined in relation to event-related potentials (ERPs) associated with early emotional attention capture and reactivity (the frontal N1) and later sustained emotional processing and regulation (the late positive potential (LPP)). Electroencephalography (EEG) was recorded while 22 participants passively viewed emotional and neutral pictures and completed an emotion regulation task with instructions to increase, decrease, or maintain their emotional responses. A greater preference for CMC was associated with reduced size of and satisfaction with social support, greater early (N1) attention capture by emotional stimuli, and reduced LPP amplitudes to unpleasant stimuli in the increase emotion regulatory task. These findings are discussed in the context of possible emotion- and social-regulatory functions of CMC.

It can be difficult to maintain family connections with geographically distant members. However, advances in computer-human interaction (CHI) systems, including video-mediated communication (VMC) are emerging. While VMC does not completely substitute for physical face-to-face communication, it appears to provide a sense of virtual copresence through the addition of visual and contextual cues to verbal communication between family members. The purpose of this study was to explore current patterns of VMC use, experiences, and family functioning among self-identified VMC users separated geographically from their families. A total of 341 participants (ages 18 to above 70) completed an online survey and Family APGAR. Ninty-six percent of the participants reported that VMC was the most common communication method used and 60% used VMC at least once/week. The most common reason cited for using VMC over other methods of communication was the addition of visual cues. A significant difference between the Family APGAR scores and the number of positive comments about VMC experience was also found. This exploratory study provides insight into the acceptance of VMC and its usefulness in maintaining connections with distant family members.

Social interaction in type 2 diabetes computer-mediated environments: How inherent features of the channels influence peer-to-peer interaction.

Interventions via the internet provide support to individuals managing chronic illness. The purpose of this integrative review was to determine how the features of a computer-mediated environment influence social interactions among individuals with type 2 diabetes. A combination of MeSH and keyword terms, based on the cognates of three broad groupings: social interaction, computer-mediated environments, and chronic illness, was used to search the PubMed, PsychInfo, Sociology Research Database, and Cumulative Index to Nursing and Allied Health Literature databases. Eleven articles met the inclusion criteria. Computer-mediated environments enhance an individual's ability to interact with peers while increasing the convenience of obtaining personalized support. A matrix, focused on social interaction among peers, identified themes across all articles, and five characteristics emerged: (1) the presence of synchronous and asynchronous communication, (2) the ability to connect with similar peers, (3) the presence or absence of a moderator, (4) personalization of feedback regarding individual progress and self-management, and (5) the ability of individuals to maintain choice during participation. Individuals interact with peers to obtain relevant, situation-specific information and knowledge about managing their own care. Computer-mediated environments facilitate the ability of individuals to exchange this information despite temporal or geographical barriers that may be present, thus improving T2D self-management. © The Author(s) 2015.

The effect of computer-mediated administration on self-disclosure of problems on the addiction severity index.

Butler, Stephen F; Villapiano, Albert; Malinow, Andrew

2009-12-01

People tend to disclose more personal information when communication is mediated through the use of a computer. This study was conducted to examine the impact of this phenomenon on the way respondents answer questions during computer-mediated, self-administration of the Addiction Severity Index (ASI) called the Addiction Severity Index-Multimedia Version((R)) (ASI-MV((R))). A sample of 142 clients in substance abuse treatment was administered the ASI via an interviewer and the computerized ASI-MV((R)), three to five days apart in a counterbalanced order. Seven composite scores were compared between the two test administrations using paired t-tests. Post hoc analyses examined interviewer effects. Comparisons of composite scores for each of the domains between the face-to-face administered and computer-mediated, self-administered ASI revealed that significantly greater problem severity was reported by clients in five of the seven domains during administration of the computer-mediated, self-administered version compared to the trained interviewer version. Item analyses identified certain items as responsible for significant differences, especially those asking clients to rate need for treatment. All items that were significantly different between the two modes of administration revealed greater problem severity reported on the ASI-MV((R)) as compared to the interview administered assessment. Post hoc analyses yielded significant interviewer effects on four of the five domains where differences were observed. These data support a growing literature documenting a tendency for respondents to be more self-disclosing in a computer-mediated format over a face-to-face interview. Differences in interviewer skill in establishing rapport may account for these observations.

The role of beliefs in lexical alignment: evidence from dialogs with humans and computers.

PubMed

2011-10-01

Five experiments examined the extent to which speakers' alignment (i.e., convergence) on words in dialog is mediated by beliefs about their interlocutor. To do this, we told participants that they were interacting with another person or a computer in a task in which they alternated between selecting pictures that matched their 'partner's' descriptions and naming pictures themselves (though in reality all responses were scripted). In both text- and speech-based dialog, participants tended to repeat their partner's choice of referring expression. However, they showed a stronger tendency to align with 'computer' than with 'human' partners, and with computers that were presented as less capable than with computers that were presented as more capable. The tendency to align therefore appears to be mediated by beliefs, with the relevant beliefs relating to an interlocutor's perceived communicative capacity. Copyright © 2011 Elsevier B.V.

Diamantaki, Katerina; Rizopoulos, Charalampos; Charitos, Dimitris; Kaimakamis, Nikos

This chapter investigates the social implications of locative media (LM) use and attempts to outline a theoretical framework that may support the design and implementation of location-based applications. Furthermore, it stresses the significance of physical space and location awareness as important factors that influence both human-computer interaction and computer-mediated communication. The chapter documents part of the theoretical aspect of the research undertaken as part of LOcation-based Communication Urban NETwork (LOCUNET), a project that aims to investigate the way users interact with one another (human-computer-human interaction aspect) and with the location-based system itself (human-computer interaction aspect). A number of relevant theoretical approaches are discussed in an attempt to provide a holistic theoretical background for LM use. Additionally, the actual implementation of the LOCUNET system is described and some of the findings are discussed.

Tools for Analyzing Computing Resource Management Strategies and Algorithms for SDR Clouds

NASA Astrophysics Data System (ADS)

Marojevic, Vuk; Gomez-Miguelez, Ismael; Gelonch, Antoni

2012-09-01

Software defined radio (SDR) clouds centralize the computing resources of base stations. The computing resource pool is shared between radio operators and dynamically loads and unloads digital signal processing chains for providing wireless communications services on demand. Each new user session request particularly requires the allocation of computing resources for executing the corresponding SDR transceivers. The huge amount of computing resources of SDR cloud data centers and the numerous session requests at certain hours of a day require an efficient computing resource management. We propose a hierarchical approach, where the data center is divided in clusters that are managed in a distributed way. This paper presents a set of computing resource management tools for analyzing computing resource management strategies and algorithms for SDR clouds. We use the tools for evaluating a different strategies and algorithms. The results show that more sophisticated algorithms can achieve higher resource occupations and that a tradeoff exists between cluster size and algorithm complexity.

2017-08-01

In this work, we describe a simple module that could be ubiquitous for quantum information based applications. The basic modules comprises a single NV- center in diamond embedded in an optical cavity, where the cavity mediates interactions between photons and the electron spin (enabling entanglement distribution and efficient readout), while the nuclear spins constitutes a long-lived quantum memories capable of storing and processing quantum information. We discuss how a network of connected modules can be used for distributed metrology, communication and computation applications. Finally, we investigate the possible use of alternative diamond centers (SiV/GeV) within the module and illustrate potential advantages.

High-Performance Data Analysis Tools for Sun-Earth Connection Missions

NASA Technical Reports Server (NTRS)

Messmer, Peter

2011-01-01

The data analysis tool of choice for many Sun-Earth Connection missions is the Interactive Data Language (IDL) by ITT VIS. The increasing amount of data produced by these missions and the increasing complexity of image processing algorithms requires access to higher computing power. Parallel computing is a cost-effective way to increase the speed of computation, but algorithms oftentimes have to be modified to take advantage of parallel systems. Enhancing IDL to work on clusters gives scientists access to increased performance in a familiar programming environment. The goal of this project was to enable IDL applications to benefit from both computing clusters as well as graphics processing units (GPUs) for accelerating data analysis tasks. The tool suite developed in this project enables scientists now to solve demanding data analysis problems in IDL that previously required specialized software, and it allows them to be solved orders of magnitude faster than on conventional PCs. The tool suite consists of three components: (1) TaskDL, a software tool that simplifies the creation and management of task farms, collections of tasks that can be processed independently and require only small amounts of data communication; (2) mpiDL, a tool that allows IDL developers to use the Message Passing Interface (MPI) inside IDL for problems that require large amounts of data to be exchanged among multiple processors; and (3) GPULib, a tool that simplifies the use of GPUs as mathematical coprocessors from within IDL. mpiDL is unique in its support for the full MPI standard and its support of a broad range of MPI implementations. GPULib is unique in enabling users to take advantage of an inexpensive piece of hardware, possibly already installed in their computer, and achieve orders of magnitude faster execution time for numerically complex algorithms. TaskDL enables the simple setup and management of task farms on compute clusters. The products developed in this project have the potential to interact, so one can build a cluster of PCs, each equipped with a GPU, and use mpiDL to communicate between the nodes and GPULib to accelerate the computations on each node.

Is Technology-Mediated Parental Monitoring Related to Adolescent Substance Use?

PubMed

Rudi, Jessie; Dworkin, Jodi

2018-01-03

Prevention researchers have identified parental monitoring leading to parental knowledge to be a protective factor against adolescent substance use. In today's digital society, parental monitoring can occur using technology-mediated communication methods, such as text messaging, email, and social networking sites. The current study aimed to identify patterns, or clusters, of in-person and technology-mediated monitoring behaviors, and examine differences between the patterns (clusters) in adolescent substance use. Cross-sectional survey data were collected from 289 parents of adolescents using Facebook and Amazon Mechanical Turk (MTurk). Cluster analyses were computed to identify patterns of in-person and technology-mediated monitoring behaviors, and chi-square analyses were computed to examine differences in substance use between the identified clusters. Three monitoring clusters were identified: a moderate in-person and moderate technology-mediated monitoring cluster (moderate-moderate), a high in-person and high technology-mediated monitoring cluster (high-high), and a high in-person and low technology-mediated monitoring cluster (high-low). Higher frequency of technology-mediated parental monitoring was not associated with lower levels of substance use. Results show that higher levels of technology-mediated parental monitoring may not be associated with adolescent substance use.

Recent technological advances have provided many youth with daily, almost continuous cell-phone and Internet connectivity through portable devices. Young people's experiences with computer-mediated communication (CMC) and their views about how this form of communication affects their health have not been fully explored in the scientific literature. A purposeful maximum variation sample of young people (aged 11-15 years) across Ontario was identified, using key informants for recruitment. The young people participated in seven focus groups (involving a total of 40 adolescents), and discussed various aspects of health including the health impacts of CMC. Inductive content analysis of the focus group transcripts revealed two overarching concepts: first, that the relationship between health and the potential impacts of CMC is multidimensional; and secondly, that there exists a duality of both positive and negative potential influences of CMC on health. Within this framework, four themes were identified involving CMC and: (1) physical activity, (2) negative mental and emotional disturbance, (3) mindfulness, and (4) relationships. With this knowledge, targeted strategies for healthy technology use that draw on the perspectives of young people can be developed, and can then be implemented by parents, teachers, and youth themselves.

Bounds on the power of proofs and advice in general physical theories.

PubMed

Lee, Ciarán M; Hoban, Matty J

2016-06-01

Quantum theory presents us with the tools for computational and communication advantages over classical theory. One approach to uncovering the source of these advantages is to determine how computation and communication power vary as quantum theory is replaced by other operationally defined theories from a broad framework of such theories. Such investigations may reveal some of the key physical features required for powerful computation and communication. In this paper, we investigate how simple physical principles bound the power of two different computational paradigms which combine computation and communication in a non-trivial fashion: computation with advice and interactive proof systems. We show that the existence of non-trivial dynamics in a theory implies a bound on the power of computation with advice. Moreover, we provide an explicit example of a theory with no non-trivial dynamics in which the power of computation with advice is unbounded. Finally, we show that the power of simple interactive proof systems in theories where local measurements suffice for tomography is non-trivially bounded. This result provides a proof that [Formula: see text] is contained in [Formula: see text], which does not make use of any uniquely quantum structure-such as the fact that observables correspond to self-adjoint operators-and thus may be of independent interest.

Stakeholder e-Participation in Local Planning: The Camargue Park Case

NASA Astrophysics Data System (ADS)

Desquinabo, Nicolas; Ferrand, Nils; Marlier, Julie

The goal of this study is to evaluate several features and outcomes of the e-consultation organized by the Camargue Natural Park on its management plan. To estimate the benefits of the selected Internet devices, we have compared our assessment of this e-consultation with other face-to-face participative events organized on the same management plan. Following "computer-mediated communication" and deliberative theories, we expected that the tested e-tools would increase the deliberative features of the stakeholder participation. Several economic and organisational benefits were also expected. Our first results confirm the organisational benefits of this e-consultation (information gain, cost of the process, etc.). Several "deliberative" benefits have also been observed (more opinion and thematic diversity without an increase of "flames"). Nevertheless, speech is apparently more concentrated than in face-to-face events, even if many "non-posters" visited the consultation site but did not post because they had "all their comments already included".

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

In recent years, mediation analysis has emerged as a powerful tool to disentangle causal pathways from an exposure/treatment to clinically relevant outcomes. Mediation analysis has been applied in scientific fields as diverse as labour market relations and randomized clinical trials of heart disease treatments. In parallel to these applications, the underlying mathematical theory and computer tools have been refined. This combined review and tutorial will introduce the reader to modern mediation analysis including: the mathematical framework; required assumptions; and software implementation in the R package medflex. All results are illustrated using a recent study on the causal pathways stemming from the early invasive treatment of acute coronary syndrome, for which the rich Danish population registers allow us to follow patients' medication use and more after being discharged from hospital.

Performance management of multiple access communication networks

NASA Astrophysics Data System (ADS)

Lee, Suk; Ray, Asok

1993-12-01

This paper focuses on conceptual design, development, and implementation of a performance management tool for computer communication networks to serve large-scale integrated systems. The objective is to improve the network performance in handling various types of messages by on-line adjustment of protocol parameters. The techniques of perturbation analysis of Discrete Event Dynamic Systems (DEDS), stochastic approximation (SA), and learning automata have been used in formulating the algorithm of performance management. The efficacy of the performance management tool has been demonstrated on a network testbed. The conceptual design presented in this paper offers a step forward to bridging the gap between management standards and users' demands for efficient network operations since most standards such as ISO (International Standards Organization) and IEEE address only the architecture, services, and interfaces for network management. The proposed concept of performance management can also be used as a general framework to assist design, operation, and management of various DEDS such as computer integrated manufacturing and battlefield C(sup 3) (Command, Control, and Communications).

Performance Analysis of Scientific and Engineering Applications Using MPInside and TAU

Saini, Subhash; Mehrotra, Piyush; Taylor, Kenichi Jun Haeng; Shende, Sameer Suresh; Biswas, Rupak

2010-01-01

In this paper, we present performance analysis of two NASA applications using performance tools like Tuning and Analysis Utilities (TAU) and SGI MPInside. MITgcmUV and OVERFLOW are two production-quality applications used extensively by scientists and engineers at NASA. MITgcmUV is a global ocean simulation model, developed by the Estimating the Circulation and Climate of the Ocean (ECCO) Consortium, for solving the fluid equations of motion using the hydrostatic approximation. OVERFLOW is a general-purpose Navier-Stokes solver for computational fluid dynamics (CFD) problems. Using these tools, we analyze the MPI functions (MPI_Sendrecv, MPI_Bcast, MPI_Reduce, MPI_Allreduce, MPI_Barrier, etc.) with respect to message size of each rank, time consumed by each function, and how ranks communicate. MPI communication is further analyzed by studying the performance of MPI functions used in these two applications as a function of message size and number of cores. Finally, we present the compute time, communication time, and I/O time as a function of the number of cores.

Groups have increased sensing and cognition capabilities that typically allow them to make better decisions. However, factors such as communication biases and time constraints can lead to less-than-optimal group decisions. In this study, we use a hybrid Brain-Computer Interface (hBCI) to improve the performance of groups undertaking a realistic visual-search task. Our hBCI extracts neural information from EEG signals and combines it with response times to build an estimate of the decision confidence. This is used to weigh individual responses, resulting in improved group decisions. We compare the performance of hBCI-assisted groups with the performance of non-BCI groups using standard majority voting, and non-BCI groups using weighted voting based on reported decision confidence. We also investigate the impact on group performance of a computer-mediated form of communication between members. Results across three experiments suggest that the hBCI provides significant advantages over non-BCI decision methods in all cases. We also found that our form of communication increases individual error rates by almost 50% compared to non-communicating observers, which also results in worse group performance. Communication also makes reported confidence uncorrelated with the decision correctness, thereby nullifying its value in weighing votes. In summary, best decisions are achieved by hBCI-assisted, non-communicating groups.

Parallelization of Nullspace Algorithm for the computation of metabolic pathways

Jevremović, Dimitrije; Trinh, Cong T.; Srienc, Friedrich; Sosa, Carlos P.; Boley, Daniel

2011-01-01

Elementary mode analysis is a useful metabolic pathway analysis tool in understanding and analyzing cellular metabolism, since elementary modes can represent metabolic pathways with unique and minimal sets of enzyme-catalyzed reactions of a metabolic network under steady state conditions. However, computation of the elementary modes of a genome- scale metabolic network with 100–1000 reactions is very expensive and sometimes not feasible with the commonly used serial Nullspace Algorithm. In this work, we develop a distributed memory parallelization of the Nullspace Algorithm to handle efficiently the computation of the elementary modes of a large metabolic network. We give an implementation in C++ language with the support of MPI library functions for the parallel communication. Our proposed algorithm is accompanied with an analysis of the complexity and identification of major bottlenecks during computation of all possible pathways of a large metabolic network. The algorithm includes methods to achieve load balancing among the compute-nodes and specific communication patterns to reduce the communication overhead and improve efficiency. PMID:22058581

The first aim for this paper was to examine gender and age differences in the intensity of usage of information and communication technology (ICT: computer for digital playing, writing and e-mailing and communication, and Internet surfing, and mobile phone). Second, we modelled the possible mediating role of sleeping habits and waking-time tiredness in the association between ICT usage and perceived health (health complaints, musculoskeletal symptoms, health status). The participants were 7292 Finns aged 12, 14, 16 and 18 years responding to a postal enquiry (response rate 70%). The results showed that boys played digital games and used Internet more often than girls, whose mobile phone usage was more intensive. Structural equation model analyses substantiated the mediating hypothesis: intensive ICT-usage was associated with poor perceived health particularly or only when it negatively affected sleeping habits, which in turn was associated with increased waking-time tiredness. The associations were gender-specific especially among older adolescents (16- and 18-year olds). Intensive computer usage forms a risk for boys', and intensive mobile phone usage for girls' perceived health through the mediating links. Girls were vulnerable to the negative consequences of intensive mobile phone usage, as it associated with perceived health complaints and musculoskeletal symptoms both directly and through deteriorated sleep and increased waking-time tiredness. The results of gender-specific ICT usage and vulnerability are discussed as reflecting gendered psychophysiological, psychological and social developmental demands.

The Space Shuttle Ultra High Frequency (UHF) communications system is planned to provide Radio Frequency (RF) coverage for astronauts working underside of the Space Shuttle Orbiter (SSO) for thermal tile inspection and repairing. This study is to assess the Space Shuttle UHF communication performance for astronauts in the shadow region without line-of-sight (LOS) to the Space Shuttle and Space Station UHF antennas. To insure the RF coverage performance at anticipated astronaut worksites, the link margin between the UHF antennas and Extravehicular Activity (EVA) Astronauts with significant vehicle structure blockage was analyzed. A series of near-field measurements were performed using the NASA/JSC Anechoic Chamber Antenna test facilities. Computational investigations were also performed using the electromagnetic modeling techniques. The computer simulation tool based on the Geometrical Theory of Diffraction (GTD) was used to compute the signal strengths. The signal strength was obtained by computing the reflected and diffracted fields along the propagation paths between the transmitting and receiving antennas. Based on the results obtained in this study, RF coverage for UHF communication links was determined for the anticipated astronaut worksite in the shadow region underneath the Space Shuttle.

SPSS and SAS programming for the testing of mediation models.

Dudley, William N; Benuzillo, Jose G; Carrico, Mineh S

2004-01-01

Mediation modeling can explain the nature of the relation among three or more variables. In addition, it can be used to show how a variable mediates the relation between levels of intervention and outcome. The Sobel test, developed in 1990, provides a statistical method for determining the influence of a mediator on an intervention or outcome. Although interactive Web-based and stand-alone methods exist for computing the Sobel test, SPSS and SAS programs that automatically run the required regression analyses and computations increase the accessibility of mediation modeling to nursing researchers. To illustrate the utility of the Sobel test and to make this programming available to the Nursing Research audience in both SAS and SPSS. The history, logic, and technical aspects of mediation testing are introduced. The syntax files sobel.sps and sobel.sas, created to automate the computation of the regression analysis and test statistic, are available from the corresponding author. The reported programming allows the user to complete mediation testing with the user's own data in a single-step fashion. A technical manual included with the programming provides instruction on program use and interpretation of the output. Mediation modeling is a useful tool for describing the relation between three or more variables. Programming and manuals for using this model are made available.

Dynamic Load-Balancing for Distributed Heterogeneous Computing of Parallel CFD Problems

NASA Technical Reports Server (NTRS)

Ecer, A.; Chien, Y. P.; Boenisch, T.; Akay, H. U.

2000-01-01

The developed methodology is aimed at improving the efficiency of executing block-structured algorithms on parallel, distributed, heterogeneous computers. The basic approach of these algorithms is to divide the flow domain into many sub- domains called blocks, and solve the governing equations over these blocks. Dynamic load balancing problem is defined as the efficient distribution of the blocks among the available processors over a period of several hours of computations. In environments with computers of different architecture, operating systems, CPU speed, memory size, load, and network speed, balancing the loads and managing the communication between processors becomes crucial. Load balancing software tools for mutually dependent parallel processes have been created to efficiently utilize an advanced computation environment and algorithms. These tools are dynamic in nature because of the chances in the computer environment during execution time. More recently, these tools were extended to a second operating system: NT. In this paper, the problems associated with this application will be discussed. Also, the developed algorithms were combined with the load sharing capability of LSF to efficiently utilize workstation clusters for parallel computing. Finally, results will be presented on running a NASA based code ADPAC to demonstrate the developed tools for dynamic load balancing.

This study sought to determine the effects of automated primary care physician (PCP) communication and patient safety tools, including computerized discharge medication reconciliation, on discharge medication errors and posthospitalization patient outcomes, using a pre-post quasi-experimental study design, in hospitalized medical patients with ≥2 comorbidities and ≥5 chronic medications, at a single center. The primary outcome was discharge medication errors, compared before and after rollout of these tools. Secondary outcomes were 30-day rehospitalization, emergency department visit, and PCP follow-up visit rates. This study found that discharge medication errors were lower post intervention (odds ratio = 0.57; 95% confidence interval = 0.44-0.74; P < .001). Clinically important errors, with the potential for serious or life-threatening harm, and 30-day patient outcomes were not significantly different between study periods. Thus, automated health system-based communication and patient safety tools, including computerized discharge medication reconciliation, decreased hospital discharge medication errors in medically complex patients. © The Author(s) 2015.

Modern handheld devices and wireless communications foster new kinds of communication and interaction that can define new approaches to teaching and learning. Mobile learning (m-learning) seeks to use them extensively, exactly in the same way in which e-learning uses personal computers and wired communication technologies. In this new mobile environment, new applications and educational models need to be created and tested to confirm (or reject) their validity and usefulness. In this article, we present a mobile tool aimed at self-assessment, which allows students to test their knowledge at any place and at any time. The degree to which the students' achievement improved is also evaluated, and a survey on the students' opinion of the new tool was also conducted. An experimental group of 20- to 21-year-old nursing students was chosen to test the tool. Results show that this kind of tool improves students' achievement and does not make necessary to introduce substantial changes in current teaching activities and methodology.

2015-10-01

Detecting signs of consciousness in patients with severe brain injury constitutes a real challenge for clinicians. The current gold standard in clinical diagnosis is the behavioral scale relying on motor abilities, which are often impaired or nonexistent in these patients. In this context, brain-computer interfaces (BCIs) could offer a potential complementary tool to detect signs of consciousness whilst bypassing the usual motor pathway. In addition to complementing behavioral assessments and potentially reducing error rate, BCIs could also serve as a communication tool for paralyzed but conscious patients, e.g., suffering from Locked-In Syndrome. In this paper, we report on recent work conducted by the Coma Science Group on BCI technology, aiming to optimize diagnosis and communication in patients with disorders of consciousness and Locked-In syndrome. © 2015 médecine/sciences – Inserm.

In the last 10 years migration processes have progressively increased worldwide and in Italy about 5 millions of residing migrants are estimated. To meet health needs of these new residents, effective relational and communication tools, which allow a reciprocal intercultural interaction within health care structures, are therefore necessary. This article faces the main features of the relational-communication processes associated with health promotion and care in the migrant population in Italy to the aim of identifying the key and critical points within the interaction between different cultures, focusing on the role of specific professional figures, including cultural mediators and health educators. Within the activity of HIV phone counselling operated by Psycho-sociobehavioural, Communication and Training Operating Unit of National Institute of Health in Italy, an intercultural approach was successfully experienced in a project targeted to migrants (2007-2008). Specifically, the presence of cultural mediators answering in the languages of main migrants' groups allowed the increase of calls from migrant people and of the information provided.

SMC: SCENIC Model Control

2015-01-01

NASAs Space Communications and Navigation (SCaN) program manages three active networks: the Near Earth Network, the Space Network, and the Deep Space Network. These networks simultaneously support NASA missions and provide communications services to customers worldwide. To efficiently manage these resources and their capabilities, a team of student interns at the NASA Glenn Research Center is developing a distributed system to model the SCaN networks. Once complete, the system shall provide a platform that enables users to perform capacity modeling of current and prospective missions with finer-grained control of information between several simulation and modeling tools. This will enable the SCaN program to access a holistic view of its networks and simulate the effects of modifications in order to provide NASA with decisional information. The development of this capacity modeling system is managed by NASAs Strategic Center for Education, Networking, Integration, and Communication (SCENIC). Three primary third-party software tools offer their unique abilities in different stages of the simulation process. MagicDraw provides UMLSysML modeling, AGIs Systems Tool Kit simulates the physical transmission parameters and de-conflicts scheduled communication, and Riverbed Modeler (formerly OPNET) simulates communication protocols and packet-based networking. SCENIC developers are building custom software extensions to integrate these components in an end-to-end space communications modeling platform. A central control module acts as the hub for report-based messaging between client wrappers. Backend databases provide information related to mission parameters and ground station configurations, while the end user defines scenario-specific attributes for the model. The eight SCENIC interns are working under the direction of their mentors to complete an initial version of this capacity modeling system during the summer of 2015. The intern team is composed of four students in Computer Science, two in Computer Engineering, one in Electrical Engineering, and one studying Space Systems Engineering.

The iPad and EFL Digital Literacy

NASA Astrophysics Data System (ADS)

Meurant, Robert C.

In future, the uses of English by non-native speakers will predominantly be online, using English language digital resources, and in computer-mediated communication with other non-native speakers of English. Thus for Korea to be competitive in the global economy, its EFL should develop L2 Digital Literacy in English. With its fast Internet connections, Korea is the most wired nation on Earth; but ICT facilities in educational institutions need reorganization. Opportunities for computer-mediated second language learning need to be increased, providing multimedia-capable, mobile web solutions that put the Internet into the hands of all students and teachers. Wi-Fi networked campuses allow any campus space to act as a wireless classroom. Every classroom should have a teacher's computer console. All students should be provided with adequate computing facilities, that are available anywhere, anytime. Ubiquitous computing has now become feasible by providing every student on enrollment with a tablet: a Wi-Fi+3G enabled Apple iPad.

It is fundamental for the flourishing biological cells that membrane proteins mediate the process. Membrane-embedded transporters move ions and larger solutes across membranes; receptors mediate communication between the cell and its environment and membrane-embedded enzymes catalyze chemical reactions. Understanding these mechanisms of action requires knowledge of how the proteins couple to their fluid, hydrated lipid membrane environment. Here, we present here current studies in computational and experimental membrane protein biophysics, and show how they address outstanding challenges in understanding the complex environmental effects on the structure, function, and dynamics of membrane proteins.

Computational fluid dynamics uses in fluid dynamics/aerodynamics education

NASA Technical Reports Server (NTRS)

Holst, Terry L.

1994-01-01

The field of computational fluid dynamics (CFD) has advanced to the point where it can now be used for the purpose of fluid dynamics physics education. Because of the tremendous wealth of information available from numerical simulation, certain fundamental concepts can be efficiently communicated using an interactive graphical interrogation of the appropriate numerical simulation data base. In other situations, a large amount of aerodynamic information can be communicated to the student by interactive use of simple CFD tools on a workstation or even in a personal computer environment. The emphasis in this presentation is to discuss ideas for how this process might be implemented. Specific examples, taken from previous publications, will be used to highlight the presentation.

Geoscience Through the Lens of Art: a collaborative course of science and art for undergraduates of various disciplines

NASA Astrophysics Data System (ADS)

Ellins, K. K.; Eriksson, S. C.; Samsel, F.; Lavier, L.

2017-12-01

A new undergraduate, upper level geoscience course was developed and taught by faculty and staff of the UT Austin Jackson School of Geosciences, the Center for Agile Technology, and the Texas Advanced Computational Center. The course examined the role of the visual arts in placing the scientific process and knowledge in a broader context and introduced students to innovations in the visual arts that promote scientific investigation through collaboration between geoscientists and artists. The course addressed (1) the role of the visual arts in teaching geoscience concepts and promoting geoscience learning; (2) the application of innovative visualization and artistic techniques to large volumes of geoscience data to enhance scientific understanding and to move scientific investigation forward; and (3) the illustrative power of art to communicate geoscience to the public. In-class activities and discussions, computer lab instruction on the application of Paraview software, reading assignments, lectures, and group projects with presentations comprised the two-credit, semester-long "special topics" course, which was taken by geoscience, computer science, and engineering students. Assessment of student learning was carried out by the instructors and course evaluation was done by an external evaluator using rubrics, likert-scale surveys and focus goups. The course achieved its goals of students' learning the concepts and techniques of the visual arts. The final projects demonstrated this, along with the communication of geologic concepts using what they had learned in the course. The basic skill of sketching for learning and using best practices in visual communication were used extensively and, in most cases, very effectively. The use of an advanced visualization tool, Paraview, was received with mixed reviews because of the lack of time to really learn the tool and the fact that it is not a tool used routinely in geoscience. Those senior students with advanced computer skills saw the importance of this tool. Students worked in teams, more or less effectively, and made suggestions for improving future offerings of the course.

Learning Communities in Teacher Education: The impact of e-competence

NASA Astrophysics Data System (ADS)

Elster, Doris

2010-11-01

The present article reports on the results of a three-year German-wide program Biology in Context (bik). In this program teachers and researchers worked together in 10 learning communities with the goal of enhancing the quality of teaching and learning in biology classrooms as mandated by the recently passed National Educational Standards for the lower secondary level. In addition to face-to-face meetings, computers were used as the tools for communication and collaboration. Computers enabled the mutual sharing of information among the participants, as well as the planning and documenting of tasks and teaching units. Furthermore, they promoted the reflection of the process and the refinement of the products. Data were collected from questionnaires and structured interviews with teachers, researchers, and coordinators. The analysis identified teacher profiles with regard to their attitudes towards implementing the bik concept, their use of computers, and the change of classroom activities. The results exposed several main tendencies. (1) The participant teachers largely utilized Information and Communication Technology (ICT) tools for the construction of tasks and units and for collaboration with each other. (2) These tools were, however, less useful for instructional purposes, learning, and knowledge creation. (3) ICT tools were hardly used for reflection of professional experiences. (4) Teacher use of ICT tools increased from the first to the third year. The study concludes that information literacy skills have a strong impact on the persistence of learning communities. Further research should be conducted to adopt a mixed form (blended form) of learning.

For physicians, hand-held computers are gaining popularity as point of care reference tools. The convergence of hand-held computers, the Internet, and wireless networks will enable these devices to assume more essential roles as mobile transmitters and receivers of digital medical Information. In addition to serving as portable medical reference sources, these devices can be Internet-enabled, allowing them to communicate over wireless wide and local area networks. With enhanced wireless connectivity, hand-held computers can be used at the point of patient care for charge capture, electronic prescribing, laboratory test ordering, laboratory result retrieval, web access, e-mail communication, and other clinical and administrative tasks. Physicians In virtually every medical specialty have begun using these devices in various ways. This review of hand-held computer use in dermatology illustrates practical examples of the many different ways hand-held computers can be effectively used by the practicing dermatologist.

Perceptions of the influence of computer-mediated communication on the health and well-being of early adolescents

PubMed Central

Favotto, Lindsay; Michaelson, Valerie; Davison, Colleen

2017-01-01

ABSTRACT Recent technological advances have provided many youth with daily, almost continuous cell-phone and Internet connectivity through portable devices. Young people’s experiences with computer-mediated communication (CMC) and their views about how this form of communication affects their health have not been fully explored in the scientific literature. A purposeful maximum variation sample of young people (aged 11–15 years) across Ontario was identified, using key informants for recruitment. The young people participated in seven focus groups (involving a total of 40 adolescents), and discussed various aspects of health including the health impacts of CMC. Inductive content analysis of the focus group transcripts revealed two overarching concepts: first, that the relationship between health and the potential impacts of CMC is multidimensional; and secondly, that there exists a duality of both positive and negative potential influences of CMC on health. Within this framework, four themes were identified involving CMC and: (1) physical activity, (2) negative mental and emotional disturbance, (3) mindfulness, and (4) relationships. With this knowledge, targeted strategies for healthy technology use that draw on the perspectives of young people can be developed, and can then be implemented by parents, teachers, and youth themselves.

How do individuals with Asperger syndrome respond to nonliteral language and inappropriate requests in computer-mediated communication?

PubMed

Rajendran, Gnanathusharan; Mitchell, Peter; Rickards, Hugh

2005-08-01

Computer-mediated communication in individuals with Asperger syndrome, Tourette syndrome and normal controls was explored with a program called Bubble Dialogue (Gray, Creighton, McMahon, and Cunninghamn (1991)) in which the users type text into speech bubbles. Two scenarios, based on Happé (1994) were adapted to investigate understanding of figure of speech and sarcasm, and a third, developed by ourselves, looked at responses to inappropriate requests (lending money and disclosing home address on a first meeting). Dialogue transcripts were assessed by 62 raters who were blind to the clinical diagnoses. Hierarchical linear modelling revealed that rated understanding of a figure of speech was predicted mainly by verbal ability and executive ability, as well as by clinical diagnosis, whereas handling inappropriate requests was predicted by age, verbal ability, executive ability and diagnosis. Notably, the Tourette comparison group showed better understanding than the Asperger group in interpreting a figure of speech and handling inappropriate requests, and differences between these groups were possibly attributable to individual differences in executive ability. In contrast, understanding sarcasm was predicted by age but not by either verbal ability, executive ability or clinical diagnosis. Evidently, there is a complicated relation between Asperger syndrome, verbal ability and executive abilities with respect to communicative performance.

REE radiation fault model: a tool for organizing and communication radiation test data and construction COTS based spacebourne computing systems

NASA Technical Reports Server (NTRS)

Ferraro, R.; Some, R.

2002-01-01

The growth in data rates of instruments on future NASA spacecraft continues to outstrip the improvement in communications bandwidth and processing capabilities of radiation-hardened computers. Sophisticated autonomous operations strategies will further increase the processing workload. Given the reductions in spacecraft size and available power, standard radiation hardened computing systems alone will not be able to address the requirements of future missions. The REE project was intended to overcome this obstacle by developing a COTS- based supercomputer suitable for use as a science and autonomy data processor in most space environments. This development required a detailed knowledge of system behavior in the presence of Single Event Effect (SEE) induced faults so that mitigation strategies could be designed to recover system level reliability while maintaining the COTS throughput advantage. The REE project has developed a suite of tools and a methodology for predicting SEU induced transient fault rates in a range of natural space environments from ground-based radiation testing of component parts. In this paper we provide an overview of this methodology and tool set with a concentration on the radiation fault model and its use in the REE system development methodology. Using test data reported elsewhere in this and other conferences, we predict upset rates for a particular COTS single board computer configuration in several space environments.

A simple and inexpensive method of preoperative computer imaging for rhinoplasty.

Ewart, Christopher J; Leonard, Christopher J; Harper, J Garrett; Yu, Jack

2006-01-01

GOALS/PURPOSE: Despite concerns of legal liability, preoperative computer imaging has become a popular tool for the plastic surgeon. The ability to project possible surgical outcomes can facilitate communication between the patient and surgeon. It can be an effective tool in the education and training of residents. Unfortunately, these imaging programs are expensive and have a steep learning curve. The purpose of this paper is to present a relatively inexpensive method of preoperative computer imaging with a reasonable learning curve. The price of currently available imaging programs was acquired through an online search, and inquiries were made to the software distributors. Their prices were compared to Adobe PhotoShop, which has special filters called "liquify" and "photocopy." It was used in the preoperative computer planning of 2 patients who presented for rhinoplasty at our institution. Projected images were created based on harmonious discussions between the patient and physician. Importantly, these images were presented to the patient as potential results, with no guarantees as to actual outcomes. Adobe PhotoShop can be purchased for 900-5800 dollars less than the leading computer imaging software for cosmetic rhinoplasty. Effective projected images were created using the "liquify" and "photocopy" filters in PhotoShop. Both patients had surgical planning and operations based on these images. They were satisfied with the results. Preoperative computer imaging can be a very effective tool for the plastic surgeon by providing improved physician-patient communication, increased patient confidence, and enhanced surgical planning. Adobe PhotoShop is a relatively inexpensive program that can provide these benefits using only 1 or 2 features.

Given the situation of having management and development users accessing a central computing facility and given the fact that these same users have the need for local computation and storage, the utilization of a commercially available networking system such as CP/NET from Digital Research provides the building blocks for communicating intelligent microsystems to file and print services. The major problems to be overcome in the implementation of such a network are the dearth of intelligent communication front-ends for the microcomputers and the lack of a rich set of management and software development tools.

1991-01-01

The Digital Optical Computing Program within the National Science Foundation Engineering Research Center for Opto-electronic Computing Systems has as its specific goal research on optical computing architectures suitable for use at the highest possible speeds. The program can be targeted toward exploiting the time domain because other programs in the Center are pursuing research on parallel optical systems, exploiting optical interconnection and optical devices and materials. Using a general purpose computing architecture as the focus, we are developing design techniques, tools and architecture for operation at the speed of light limit. Experimental work is being done with the somewhat low speed components currently available but with architectures which will scale up in speed as faster devices are developed. The design algorithms and tools developed for a general purpose, stored program computer are being applied to other systems such as optimally controlled optical communication networks.

Applying mobile and pervasive computer technology to enhance coordination of work in a surgical ward.

Hansen, Thomas Riisgaard; Bardram, Jakob E

2007-01-01

Collaboration, coordination, and communication are crucial in maintaining an efficient and smooth flow of work in an operating ward. This coordination, however, often comes at a high price in terms of unsuccessfully trying to get hold of people, disturbing telephone calls, looking for people, and unnecessary stress. To accommodate this situation and to increase the quality of work in operating wards, we have designed a set of pervasive computer systems which supports what we call context-mediated communication and awareness. These systems use large interactive displays, video streaming from key locations, tracking systems, and mobile devices to support social awareness and different types of communication modalities relevant to the current context. In this paper we report qualitative data from a one-year deployment of the system in a local hospital. Overall, this study shows that 75% of the participants strongly agreed that these systems had made their work easier.
