Today's advanced network management systems can automate many aspects of the tactical networking operations within a military domain. However, automation of joint and coalition tactical networking across multiple domains remains challenging. Due to potentially conflicting goals and priorities, human agreement is often required before implementation into the network operations. This is further complicated by incompatible network management systems and security policies, rendering it difficult to implement automatic network management, thus requiring manual human intervention to the communication protocols used at various network routers and endpoints. This process of manual human intervention is tedious, error-prone, and slow. In order to facilitate a better solution, we are pursuing a technology which makes network management automated, reliable, and fast. Automating the negotiation of the common network communication parameters between different parties is the subject of this paper. We present the technology that enables inter-force dynamic communication resource negotiations to enable ad-hoc inter-operation in the field between force domains, without pre-planning. It also will enable a dynamic response to changing conditions within the area of operations. Our solution enables the rapid blending of intra-domain policies so that the forces involved are able to inter-operate effectively without overwhelming each other's networks with in-appropriate or un-warranted traffic. It will evaluate the policy rules and configuration data for each of the domains, then generate a compatible inter-domain policy and configuration that will update the gateway systems between the two domains.

To analyze the communication resources reported by managers in the business environment and compare the resources used to those reported by business professionals. 82 professionals volunteered to participate in the research, divided into 50 managers (MP) and 32 business professionals (BP) from industry section in Caxias do Sul and the surrounding region (Brazil). A questionnaire with 4 topics was used: personal data, self-assessment of communicative behavior, self-assessment of communicative resources, and selection of positive and negative resources influencing communication. Regarding communicative behavior, both groups reported normal voice but with significant differences regarding the use of softness in communication, 25% of MP and only 4% of BP. Both groups selected the following main positive resources: knowledge of subject, use of proper vocabulary, and objectivity. The negative resources were, similarly, the lack of subject domain, criticism or prejudgment, and improper vocabulary. Finally, analyzing the degree of influence of each communicative resource, the MP highlighted tone of voice as an important positive resource, while the BP pointed the subject domain. Still, the monotonous voice for MP and nervousness for BP were indicated as the main negative influences. Managers value more communicative resources connected to communicative attitude, such as tone of voice and expression, while business professionals worry about demonstrating security and technical understanding of the subject.

The use of Internet-enabled technology (information and communication technology such as smartphone applications) may enrich information exchange among providers and, consequently, improve health care delivery. The purpose of this systematic review was to gain a greater understanding of the role that Internet-enabled technology plays in enhancing communication among physicians. Studies were identified through a search in three electronic platforms: the Association for Computing Machinery Digital Library, ProQuest, and Web of Science. The search identified 5140 articles; of these, 21 met all inclusion criteria. In general, physicians were satisfied with Internet-enabled technology, but consensus was lacking regarding whether Internet-enabled technology improved efficiency or made a difference to clinical decision-making. Internet-enabled technology can play an important role in enhancing communication among physicians, but the extent of that benefit is influenced by (1) the impact of Internet-enabled technology on existing work practices, (2) the availability of adequate resources, and (3) the nature of institutional elements, such as privacy legislation.

Ter Hoeven, Claartje L; van Zoonen, Ward; Fonner, Kathryn L

2016-04-02

Technological advancements in the workplace frequently have produced contradictory effects by facilitating accessibility and efficiency while increasing interruptions and unpredictability. We combine insights from organizational paradoxes and the job demands-resources model to construct a framework identifying positive and negative mechanisms in the relationship between communication technology use (CTU) and employee well-being, operationalized as work engagement and burnout. In this study of Dutch workers, we demonstrate that CTU increases well-being through positive pathways (accessibility and efficiency) and decreases well-being through negative pathways (interruptions and unpredictability). We highlight the importance of (1) investigating CTU resources and demands simultaneously to grasp the relationship between CTU and employee well-being, and (2) considering CTU's downsides to successfully implement new communication technologies and flexible work designs.

Richard Chinomona

2013-08-01

Full Text Available There is an increasing awareness about the paramount importance of information technology within business in the context of large businesses. However, research about the investigation of the role of information technology resources in fostering collaborative communication, network governance and relationship longevity in the small and medium enterprise sector has remained scant. The primary objective of this study was to investigate the influence of information technology on collaborative communication, network governance and relationship longevity in Zimbabwe’s SME sector. Five research hypotheses were posited and sample data from 162 small and medium enterprise suppliers were collected and used to empirically test the hypotheses. The results of this study showed that information technology resources positively influenced small and medium enterprise suppliers’ collaborative communication, network governance and consequential relationship longevity with their buyers in a significant way. Overall, the current study findings provided tentative support to the proposition that information technology resources, collaborative communication and network governance should be recognised as significant antecedents for improved relationship longevity between suppliers and their buyers in the SME setting. Therefore, managers in the small and medium enterprise sector and small and medium enterprise owners need to pay attention to both collaborative communication and network governance in order to optimise information technology resource impact on their relationship longevity with their business counterparts. Limitations and future research directions were also indicated.

Next-generation Mars communications networks will provide communications and navigation services to a wide variety of Mars science vehicles including: spacecraft that are arriving at Mars, spacecraft that are entering and descending in the Mars atmosphere, scientific orbiter spacecraft, spacecraft that return Mars samples to Earth, landers, rovers, aerobots, airplanes, and sensing pods. In the current architecture plans, the communication services will be provided using capabilities deployed on the science vehicles as well as dedicated communication satellites that will together make up the Mars network. This network will evolve as additional vehicles arrive, depart or end their useful missions. Cost savings and increased reliability will result from the ability to share communication services between missions. This paper discusses the basic architecture that is needed to support the Mars Communications Network part of NASA's Space Science Enterprise (SSE) communications architecture. The network may use various networking technologies such as those employed in the terrestrial Internet, as well as special purpose deep-space protocols to move data and commands autonomously between vehicles, at disparate Mars vicinity sites (on the surface or in near-Mars space) and between Mars vehicles and earthbound users. The architecture of the spacecraft on-board local communications is being reconsidered in light of these new networking requirements. The trend towards increasingly autonomous operation of the spacecraft is aimed at reducing the dependence on resource scheduling provided by Earth-based operators and increasing system fault tolerance. However, these benefits will result in increased communication and software development requirements. As a result, the envisioned Mars communications infrastructure requires both hardware and protocol technology advancements. This paper will describe a number of the critical technology needs and some of the ongoing research

Resource Allocation for Multicell Device-to-Device Communications in Cellular Network: A Game Theoretic Approach

Directory of Open Access Journals (Sweden)

Jun Huang

2015-08-01

Full Text Available Device-to-Device (D2D communication has recently emerged as a promising technology to improve the capacity and coverage of cellular systems. To successfully implement D2D communications underlaying a cellular network, resource allocation for D2D links plays a critical role. While most of prior resource allocation mechanisms for D2D communications have focused on interference within a single-cell system, this paper investigates the resource allocation problem for a multicell cellular network in which a D2D link reuses available spectrum resources of multiple cells. A repeated game theoretic approach is proposed to address the problem. In this game, the base stations (BSs act as players that compete for resource supply of D2D, and the utility of each player is formulated as revenue collected from both cellular and D2D users using resources. Extensive simulations are conducted to verify the proposed approach and the results show that it can considerably enhance the system performance in terms of sum rate and sum rate gain.

Radio resource management scheme and outage analysis for network-assisted multi-hop D2D communications

Leila Melki

2016-11-01

Full Text Available In a cellular network it's very difficult to make spectrum resource more efficiently. Device-to-Device (D2D technology enables new service opportunities, and provides high throughput and reliable communication while reducing the base station load. For better total performance, short-range D2D links and cellular links share the same radio resource and the management of interference becomes a crucial task. Here we argue that single-hop D2D technology can be used to further improve cellular networks performance if the key D2D radio resource management algorithms are suitably extended to support multi-hop D2D communications. Aiming to establish a new paradigm for the analysis and design of multi-hop D2D communications, We propose a radio resource allocation for multi-hop D2D routes based on interference avoidance approach in LTE-A networks. On top of that, we investigate the outage probability of D2D communication. We first introduce a new definition of outage probability by considering the maximum distance to be allowable for single-hop transmission. Then we study and analyze the outage performance of a multi-hop D2D route. We derive the general closed form expression of outage probability of the multi-hop D2D routes. The results demonstrate that the D2D radio, sharing the same resources as the cellular network, provide higher capacity compared to pure cellular communication where all the data is transmitted through the base station. They also demonstrate that the new method of calculation of D2D multi hop outage probability has better performance than classical method defined in the literature.

Technology transfer by multinational firms: the resource cost of transferring technological know-how

Energy Technology Data Exchange (ETDEWEB)

Teece, D J

1977-06-01

The essence of modern economic growth is the increase in the stock of useful knowledge and the extension of its application. Since the origins of technical and social innovations have never been confined to the borders of any one nation, the economic growth of all countries depends to some degree on the successful application of a transnational stock of knowledge. Nevertheless, economists have been remarkably slow in addressing themselves to the economics of international technology transfer. This paper addresses itself to this need. The starting-point is Arrow's suggestion (Am. Econ. Review, 52: 29-35 (May 1969)) that the cost of communication, or information transfer, is a fundamental factor influencing the world-wide diffusion of technology. The purpose of the paper is to examine the level and determinants of the costs involved in transferring technology. The value of the resources that have to be utilized to accomplish the successful transfer of a given manufacturing technology is used as a measure of the cost of transfer. The resource cost concept is therefore designed to reflect the ease or difficulty of transferring technological know-how from manufacturing plants in one country to manufacturing plants in another. 32 references.

2014-10-01

Full Text Available New information and communication technologies (ICTs challenge existing beliefs regarding the exchange of social resources within a network. The present study examines individuals’ perceived access to social, emotional, and instrumental resources by analyzing relational and Facebook-specific characteristics of dyadic relationships. Results suggest that the social and technical affordances of the site—including visibility of content and connections, as well as streamlined processes for interacting with a large audience—may augment existing perceptions of resource access for some ties while providing a major (or sole outlet to interact and exchange resources with others. Specifically, weaker ties appear to benefit more than strong ties from engagement in directed communication and relationship maintenance strategies, while additional variations were observed across relationship category, dyad composition, and geographic proximity. In summary, these findings provide new evidence for how positive relational gains may be derived from site use.

Cognitive Spectrum Sharing: An Enabling Wireless Communication Technology for a Wide Use of Smart Systems

Directory of Open Access Journals (Sweden)

Romano Fantacci

2016-05-01

Full Text Available A smart city is an environment where a pervasive, multi-service network is employed to provide citizens improved living conditions as well as better public safety and security. Advanced communication technologies are essential to achieve this goal. In particular, an efficient and reliable communication network plays a crucial role in providing continue, ubiquitous, and reliable interconnections among users, smart devices, and applications. As a consequence, wireless networking appears as the principal enabling communication technology despite the necessity to face severe challenges to satisfy the needs arising from a smart environment, such as explosive data volume, heterogeneous data traffic, and support of quality of service constraints. An interesting approach for meeting the growing data demand due to smart city applications is to adopt suitable methodologies to improve the usage of all potential spectrum resources. Towards this goal, a very promising solution is represented by the Cognitive Radio technology that enables context-aware capability in order to pursue an efficient use of the available communication resources according to the surrounding environment conditions. In this paper we provide a review of the characteristics, challenges, and solutions of a smart city communication architecture, based on the Cognitive Radio technology, by focusing on two new network paradigms—namely, Heterogeneous Network and Machines-to-Machines communications—that are of special interest to efficiently support smart city applications and services.

A cornerstone of sexually transmitted infection (STI) prevention is the identification, tracing, and notification of sex partners of index patients. Although partner notification reduces disease burden and prevents new infections as well as reinfections, studies show that only a limited number of partners are ever notified. Electronic communication technologies, namely, the Internet, text messaging, and phone calls (i.e., e-notification), have the potential to expand partner services. We conducted a systematic review of studies that have investigated the acceptability and utility of e-notification. We identified 23 studies that met the following criteria: (a) 9 studies presented data on the acceptability of technology-based communications for contacting sex partner(s), and (b) 14 studies reported on the utilization of communication technologies for partner notification. Studies found high levels of interest in and acceptability of e-notification; however, there was little evidence for actual use of e-notification. Taken together, results suggest that electronic communications could have their greatest impact in notifying less committed partners who would otherwise be uninformed of their STI exposure. In addition, all studies to date have been conducted in resource-rich countries, although the low cost of e-notification may have its greatest impact in resource-constrained settings. Research is needed to determine the best practices for exploiting the opportunities afforded by electronic communications for expanding STI partner services.

Clear lines of collaboration and communication among administrators, medical physicists, IT staff, equipment service engineers and vendors need to be established. In order to develop a better understanding of the clinical needs and responsibilities of these various groups, an overview of the role of IT in RO is provided. This is followed by a list of IT related tasks and a resource map. The skill set and knowledge required to implement these tasks are described for the various RO professionals. Finally, various models for assessing one's IT resource needs are described. The exposition of ideas in this white paper is intended to be broad, in order to raise the level of awareness of the RO community; the details behind these concepts will not be given here and are best left to future task group reports.

The Advanced Communication Technology Satellite (ACTS) is a key to reaching NASA's goal of developing high-risk, advanced communications technology using multiple frequency bands to support the nation's future communication needs. Using the multiple, dynamic hopping spot beams, and advanced on board switching and processing systems, ACTS will open a new era in communications satellite technology. One of the key technologies to be validated as part of the ACTS program is the multibeam antenna with rapidly reconfigurable hopping and fixed spot beam to serve users equipped with small-aperature terminals within the coverage areas. The proposed antenna technology experiments are designed to evaluate in-orbit ACTS multibeam antenna performance (radiation pattern, gain, cross pol levels, etc.).

Communication, Technology, Temporality

Full Text Available This paper proposes a media studies that foregrounds technological objects as communicative and historical agents. Specifically, I take the digital computer as a powerful catalyst of crises in communication theories and certain key features of modernity. Finally, the computer is the motor of “New Media” which is at once a set of technologies, a historical epoch, and a field of knowledge. As such the computer shapes “the new” and “the future” as History pushes its origins further in the past and its convergent quality pushes its future as a predominate medium. As treatment of information and interface suggest, communication theories observe computers, and technologies generally, for the mediated languages they either afford or foreclose to us. My project describes the figures information and interface for the different ways they can be thought of as aspects of communication. I treat information not as semantic meaning, formal or discursive language, but rather as a physical organism. Similarly an interface is not a relationship between a screen and a human visual intelligence, but is instead a reciprocal, affective and physical process of contact. I illustrate that historically there have been conceptions of information and interface complimentary to mine, fleeting as they have been in the face of a dominant temporality of mediation. I begin with a theoretically informed approach to media history, and extend it to a new theory of communication. In doing so I discuss a model of time common to popular, scientific, and critical conceptions of media technologies especially in theories of computer technology. This is a predominate model with particular rules of temporal change and causality for thinking about mediation, and limits the conditions of possibility for knowledge production about communication. I suggest a new model of time as integral to any event of observation and analysis, and that human mediation does not exhaust the

Healthcare facilities use a number of information system/information and communication technologies. Each healthcare facility faces a need to choose sourcing strategies most suitable to ensure provision of information system/information and communication technology services, processes and resources. Currently, it is possible to observe an expansion of sourcing possibilities in healthcare informatics, which creates new requirements for sourcing strategies. Thus, the aim of this article is to identify factors influencing information system/information and communication technology sourcing strategies in healthcare facilities. The identification was based on qualitative research, namely, a case study. This study provides a set of internal and external factors with their impact levels. The findings also show that not enough attention is paid to these factors during decision-making. © The Author(s) 2015.

Soviet satellite communications science and technology

Energy Technology Data Exchange (ETDEWEB)

Birch, J.N.; Campanella, S.J.; Gordon, G.D.; McElroy, D.R.; Pritchard, W.L.; Stamminger, R.

1991-08-01

This is a report by six US scientists and engineers concerning the current state of the art and projections of future Soviet satellite communications technologies. The panel members are experts in satellite stabilization, spacecraft environments, space power generation, launch systems, spacecraft communications sciences and technologies, onboard processing, ground stations, and other technologies that impact communications. The panel assessed the Soviet ability to support high-data-rate space missions at 128 Mbps by evaluating current and projected Soviet satellite communications technologies. A variety of space missions were considered, including Earth-to-Earth communications via satellites in geostationary or highly elliptical orbits, those missions that require space-to-Earth communications via a direct path and those missions that require space-to-Earth communications via a relay satellite. Soviet satellite communications capability, in most cases, is 10 years behind that of the United States and other industrialized nations. However, based upon an analysis of communications links needed to support these missions using current Soviet capabilities, it is well within the current Soviet technology to support certain space missions outlined above at rates of 128 Mbps or higher, although published literature clearly shows that the Soviet Union has not exceeded 60 Mbps in its current space system. These analyses are necessary but not sufficient to determine mission data rates, and other technologies such as onboard processing and storage could limit the mission data rate well below that which could actually be supported via the communications links. Presently, the Soviet Union appears to be content with data rates in the low-Earth-orbit relay via geostationary mode of 12 Mbps. This limit is a direct result of power amplifier limits, spacecraft antenna size, and the utilization of K{sub u}-band frequencies. 91 refs., 16 figs., 15 tabs.

Full Text Available : In the first phase of this study a model for electronic human resource management in government agencies based on new public services was explored by using software MAXQDA, then in the second phase, relationship between the elements of the theory were tested using software Smart PLS2. So the aim of this study is to design a model of electronic human resource management’s implementation at the Ministry of Communications and Information Technology. In this regard, according to Strauss and Corbin’s structured plan, five hypotheses were tested. Quantitative data analysis indicates that the pressures of the policies and global perspectives cause to move toward e-HRM. Among the contextual conditions macro structural mechanisms, considerations of actors, governance considerations have a significant impact on the strategy of new public services and therefore lead to the consequences of its implementation in public organizations. The findings suggest that e-HRM does not have a positive and meaningful impact on new public services, and in our country, although the recent political developments have somehow removed the gap between public policy makers, administrators, and the public, but there is still a long way to go.

Information technology resources assessment

Energy Technology Data Exchange (ETDEWEB)

Loken, S.C. [ed.

1993-01-01

The emphasis in Information Technology (IT) development has shifted from technology management to information management, and the tools of information management are increasingly at the disposal of end-users, people who deal with information. Moreover, the interactive capabilities of technologies such as hypertext, scientific visualization, virtual reality, video conferencing, and even database management systems have placed in the hands of users a significant amount of discretion over how these resources will be used. The emergence of high-performance networks, as well as network operating systems, improved interoperability, and platform independence of applications will eliminate technical barriers to the use of data, increase the power and range of resources that can be used cooperatively, and open up a wealth of possibilities for new applications. The very scope of these prospects for the immediate future is a problem for the IT planner or administrator. Technology procurement and implementation, integration of new technologies into the existing infrastructure, cost recovery and usage of networks and networked resources, training issues, and security concerns such as data protection and access to experiments are just some of the issues that need to be considered in the emerging IT environment. As managers we must use technology to improve competitiveness. When procuring new systems, we must take advantage of scalable resources. New resources such as distributed file systems can improve access to and efficiency of existing operating systems. In addition, we must assess opportunities to improve information worker productivity and information management through tedmologies such as distributed computational visualization and teleseminar applications.

2018-09-01

The aim of this study was to better understand nurses' and other staff members' attitudes toward the usefulness of information and communication technology in home-care settings. Research has found that beliefs about the expected benefits of information and communication technology impact the use of technology. Furthermore, inexperience with using information and communication technology may cause negative attitudes. This article is based on a questionnaire to 155 nurses and other staff members in home-care in Sogn og Fjordane county in Norway. The results revealed minimal use of information and communication technology at work; however, participants had positive attitudes regarding the potential benefits of information and communication technology use in home-care. Individuals' extensive use of and familiarity with different solutions in private lives could be an important context for explaining employees' attitudes. Given that information and communication technology is both a welfare service and a market good, this may explain individuals' positive attitudes toward information and communication technology despite their lack of experience with it at work. Experiences with information and communication technology as a market good and the way new technologies can affect work routines will affect the implementation of information and communication technology in home-care.

This year`s Information Technology Resources Assessment (ITRA) is something of a departure from traditional practice. Past assessments have concentrated on developments in fundamental technology, particularly with respect to hardware. They form an impressive chronicle of decreasing cycle times, increasing densities, decreasing costs (or, equivalently, increasing capacity and capability per dollar spent), and new system architectures, with a leavening of operating systems and languages. Past assessments have aimed -- and succeeded -- at putting information technology squarely in the spotlight; by contrast, in the first part of this assessment, we would like to move it to the background, and encourage the reader to reflect less on the continuing technological miracles of miniaturization in space and time and more on the second- and third-order implications of some possible workplace applications of these miracles. This Information Technology Resources Assessment is intended to provide a sense of technological direction for planners in projecting the hardware, software, and human resources necessary to support the diverse IT requirements of the various components of the DOE community. It is also intended to provide a sense of our new understanding of the place of IT in our organizations.

This study is based on a survey designed to determine the Information Seeking Behavior (ISB) of Astronomy and Astrophysics users in India. The main objective of the study is to determine the sources consulted and the general pattern of the information-gathering system of users and the impact of Information and Communication Technology (ICT) on the Astronomy and Astrophysics user's Information Seeking Behavior. It examines various Information and Communication Technology-based resources and methods of access and use. A descriptive sample stratified method has been used and data was collected using a questionnaire as the main tool. The response rate was 72%. Descriptive statistics were also employed and data have been presented in tables and graphs. The study is supported by earlier studies. It shows that Astronomy and Astrophysics users have developed a unique Information Seeking Behavior to carry out their education and research. The vast majority of respondents reported that more information is available from a variety of e-resources. Consequently, they are able to devote more time to seek out relevant information in the current Information and Communication Technology scenario. The study also indicates that respondents use a variety of information resources including e-resources for teaching and research. Books and online databases such as the NASA Astrophysics Data System (ADS) were considered more important as formal sources of information. E-mail and face-to-face communications are used extensively by users as informal sources of information. It also reveals that despite the presence of electronic sources, Astronomy and Astrophysics users are still using printed materials. This study should to help to improve various Information and Communication Technology-based services. It also suggests that GOI should adopt Information and Communication Technology-based Information Centers and Libraries services and recommends a network-based model for Astronomy and

Effective communication is important for quality choices of drugs and other technologies. In effective communication, the choice of messages and media must correspond to the culture and beliefs of the target groups to make them comprehend and adopt the conclusions. Messages must be presented on a regular basis. Most regulatory agencies do not have enough resources to mount effective communication programs. Private advertising agencies and other stakeholders have definite roles. Valid knowledge must be the basis of dialogues to reduce emotional disputes among various benefit groups in society.

Directory of Open Access Journals (Sweden)

Schuurman Nadine

2010-05-01

Full Text Available Abstract Background Extensive public health gains have benefited high-income countries in recent decades, however, citizens of low and middle-income countries (LMIC have largely not enjoyed the same advancements. This is in part due to the fact that public health data - the foundation for public health advances - are rarely collected in many LMIC. Injury data are particularly scarce in many low-resource settings, despite the huge associated burden of morbidity and mortality. Advances in freely-accessible and easy-to-use information and communication (ICT technology may provide the impetus for increased public health data collection in settings with limited financial and personnel resources. Methods and Results A pilot study was conducted at a hospital in Cape Town, South Africa to assess the utility and feasibility of using free (non-licensed, and easy-to-use Social Web and GeoWeb tools for injury surveillance in low-resource settings. Data entry, geocoding, data exploration, and data visualization were successfully conducted using these technologies, including Google Spreadsheet, Mapalist, BatchGeocode, and Google Earth. Conclusion This study examined the potential for Social Web and GeoWeb technologies to contribute to public health data collection and analysis in low-resource settings through an injury surveillance pilot study conducted in Cape Town, South Africa. The success of this study illustrates the great potential for these technologies to be leveraged for public health surveillance in resource-constrained environments, given their ease-of-use and low-cost, and the sharing and collaboration capabilities they afford. The possibilities and potential limitations of these technologies are discussed in relation to the study, and to the field of public health in general.

Wasting the Future: The Technological Sublime, Communications Technologies, and E-waste

Directory of Open Access Journals (Sweden)

Sebine Label

2012-08-01

Full Text Available Literally speaking, e-waste is the future of communications. E-waste is the fastest growing waste stream in the world, much of it communications technologies from cell phones to laptops, televisions to peripherals. As a result of policies of planned obsolescence working computers, cell phones, and tablets are routinely trashed. One of the most powerful and enduring discourses associated with emerging technologies is the technological sublime, in which technology is seen as intellectually, emotionally, or spiritually transcendent. It comprises a contradictory impulse that elevates technology with an almost religious fervor, while simultaneously overlooking some of the consequences of industrialism, as well as ignoring the necessity of social, economic, and governmental infrastructures necessary to the implementation and development of new technologies. The idea that a new technology will not pollute or harm the environment is a persistent, though often quickly passed over, theme in the technological sublime, echoed in discourses about emerging technologies such as the silicon chip, the internet, and other ICTs. In this paper, I make connections between the discourse of newness, the practice of planned obsolescence, and the mountains of trashed components and devices globally. Considering the global context demonstrates the realities of the penetration of ICTs and their enduring pollution and negative implications for the health of humans and nonhumans, including plants, animals, waterways, soil, air and so on. I use the discourse of the technological sublime to open up and consider the future of communications, to argue that this discourse not only stays with us but also contains within it two important and related components, the promise of ecological harmony and a future orientation. I argue that these lingering elements keep us from considering the real future of communications – e-waste – and that, as communications scholars, we must also

2017-01-01

Objectives Information and communication technology is often lauded as the key to enhancing communication among health care providers. However, its impact on interprofessional collaboration is unclear. The objective of this study was to determine the extent to which it improves communication and, subsequently, enhances interprofessional collaboration in chronic disease management. Methods A systematic review of academic literature using two electronic platforms: HealthSTAR and Web of Science (core collection and MEDLINE). To be eligible for inclusion in the review, articles needed to be peer-reviewed; accessible in English and focused on how technology supports, or might support, collaboration (through enhanced communication) in chronic disease management. Studies were assessed for quality and a narrative synthesis conducted. Results The searches identified 289 articles of which six were included in the final analysis (three used qualitative methods, two were descriptive and one used mixed methods). Various forms of information and communication technology were described including electronic health records, online communities/learning resources and telehealth/telecare. Three themes emerged from the studies that may provide insights into how communication that facilitates collaboration in chronic disease management might be enhanced: professional conflict, collective engagement and continuous learning. Conclusions The success of technology in enhancing collaboration for chronic disease management depends upon supporting the social relationships and organization in which the technology will be placed. Decision-makers should take into account and work toward balancing the impact of technology together with the professional and cultural characteristics of health care teams.

CERN Document Server

Song, Lingyang; Xu, Chen

2013-01-01

Device-to-Device (D2D) communication will become a key feature supported by next generation cellular networks, a topic of enormous importance to modern communication. Currently, D2D serves as an underlay to the cellular network as a means to increase spectral efficiency. Although D2D communication brings large benefits in terms of system capacity, it also causes interference as well as increased computation complexity to cellular networks as a result of spectrum sharing. Thus, efficient resource management must be performed to guarantee a target performance level of cellular communication.This

Improving nurse-patient communication with patients with communication impairments: hospital nurses' views on the feasibility of using mobile communication technologies.

Science.gov (United States)

Sharpe, Bridget; Hemsley, Bronwyn

2016-05-01

Nurses communicating with patients who are unable to speak often lack access to tools and technologies to support communication. Although mobile communication technologies are ubiquitous, it is not known whether their use to support communication is feasible on a busy hospital ward. The aim of this study was to determine the views of hospital nurses on the feasibility of using mobile communication technologies to support nurse-patient communication with individuals who have communication impairments. This study involved an online survey followed by a focus group, with findings analyzed across the two data sources. Nurses expected that mobile communication devices could benefit patient care but lacked access to these devices, encountered policies against use, and held concerns over privacy and confidentiality. The use of mobile communication technologies with patients who have communication difficulties is feasible and may lead to improvements in communication and care, provided environmental barriers are removed and facilitators enhanced.

Information and Communication Technologies in Creating Political Media Reality in Russia

Directory of Open Access Journals (Sweden)

Marianna Yu. Pavlyutenkova

2017-01-01

Full Text Available The article explores intended use of infocomms in creation of political media reality, acting as a virtual environment, effectively replacing reality. A noteworthy detail is that mainstreaming of information and communication technologies into political sphere substantially increases the authoritative potential for the media discourse. Those forces that assert their own media versions of events and media images for their participants have been winning in the competitive struggle amidst media discourses today. Furthermore, all available communication channels (television, media, Internet resources, mobile telecommunications are used to set up a political pseudo-environment for their information consumers, replacing political reality. The article shows what way new media resources, initially aimed at manipulating the mass consciousness in the pre-election race are being incorporated today. In particular, impressive manipulative media effects are demonstrated when a fake discourse is included in the media space. In addition, computer attacks, hacking, and the prime of independent cyber organizations fighting against the “world evil” are in effect as an instrument in the political struggle, in obtaining compromising material and interstate opposition. The work records the inclusion of graphic elements, emoji, clips in the media discourse. In general, symbols, encroaching into the politics space, become a part of the political mainstream, change the style of political demonstrations, discussions, chats that unite adherents to influence the actions of the authorities. It follows that the political media reality design, supported by the latest information and communication technologies tools, directly affects the perception of what is happening on a global scale, quickly formatting the mass consciousness.

Dance communication affects consistency, but not breadth, of resource use in pollen-foraging honey bees.

Directory of Open Access Journals (Sweden)

Matina Donaldson-Matasci

Full Text Available In groups of cooperatively foraging individuals, communication may improve the group's performance by directing foraging effort to where it is most useful. Honey bees (Apis mellifera use a specialized dance to communicate the location of floral resources. Because honey bees dance longer for more rewarding resources, communication may shift the colony's foraging effort towards higher quality resources, and thus narrow the spectrum of resource types used. To test the hypothesis that dance communication changes how much honey bee colonies specialize on particular resources, we manipulated their ability to communicate location, and assessed the relative abundance of different pollen taxa they collected. This was repeated across five natural habitats that differed in floral species richness and spatial distribution. Contrary to expectation, impairing communication did not change the number or diversity of pollen (resource types used by individual colonies per day. However, colonies with intact dance communication were more consistent in their resource use, while those with impaired communication were more likely to collect rare, novel pollen types. This suggests that communication plays an important role in shaping how much colonies invest in exploring new resources versus exploiting known ones. Furthermore, colonies that did more exploration also tended to collect less pollen overall, but only in environments with greater floral abundance per patch. In such environments, the ability to effectively exploit highly rewarding resources may be especially important-and dance communication may help colonies do just that. This could help explain how communication benefits honey bee colonies, and also why it does so only under certain environmental conditions.

Efficient resource allocation scheme for visible-light communication system

Science.gov (United States)

Kim, Woo-Chan; Bae, Chi-Sung; Cho, Dong-Ho; Shin, Hong-Seok; Jung, D. K.; Oh, Y. J.

2009-01-01

A visible-light communication utilizing LED has many advantagies such as visibility of information, high SNR (Signal to Noise Ratio), low installation cost, usage of existing illuminators, and high security. Furthermore, exponentially increasing needs and quality of LED have helped the development of visible-light communication. The visibility is the most attractive property in visible-light communication system, but it is difficult to ensure visibility and transmission efficiency simultaneously during initial access because of the small amount of initial access process signals. In this paper, we propose an efficient resource allocation scheme at initial access for ensuring visibility with high resource utilization rate and low data transmission failure rate. The performance has been evaluated through the numerical analysis and simulation results.

The spectre of uncertainty in communicating technological risk

Energy Technology Data Exchange (ETDEWEB)

Broesius, Michael T. [Univ. of California, Livermore, CA (United States)

1993-12-01

The literature does not clearly describe the potential moral and ethical conflicts that can exist between technology sponsors and the technical communicators whose job it is to present potentially risky technology to the non-technical people most likely to be imperiled by such risk. Equally important, the literature does not address the issue of uncertainty -- not the uncertainty likely to be experienced by the community at risk, but the unreliable processes and methodologies used by technology sponsors to define, quantify, and develop strategies to mitigate technological risks. In this paper, the author goes beyond a description of risk communication, the nature of the generally predictable interaction between technology advocates and non-technically trained individuals, and current trends in the field. Although that kind of information is critical to the success of any risk communication activity, and he has included it when necessary to provide background and perspective, without knowing how and why risk assessment is done, it has limited practical applicability outside the sterile, value-free vacuum in which it is usually framed. Technical communicators, particularly those responsible for communicating potential technological risk, must also understand the social, political, economic, statistical, and ethical issues they will invariably encounter.

Describe the use of assistive technology to enhance communication opportunities for older adults. A systematic review was conducted in two databases, PubMed and Web of Science, by using two different searches in each. The search was limited to original articles, in English language, including people aged 60 years and older that used any type of assistive technology for communication. The articles found in the initial search were filtered by title, abstracts and the remaining articles were fully read. Eighteen studies were included in this review after the reading of full-texts. Most of the studies included apparently healthy participants with communication limitations due to aging related changes and the others included people with some pathology that prevent them from normal communication. Four categories of assistive technology were identified: assistive technology for people with speech problems; robot or videoconferencing systems; Information and Communication Technologies and, other types of assistive technology for communication, such as hearing aids and scrapbooks. Assistive technology for communication of older adults is not only used by people with disabilities that prevent them from usual communication. They are mostly for older adults without a pathological communication problem.

Shared Communications: Volume 1. A Summary and Literature Review

Energy Technology Data Exchange (ETDEWEB)

Franzese, O

2004-09-22

This paper provides a review of examples from the literature of shared communication resources and of agencies and/or organizations that share communication resources. The primary emphasis is on rural, intelligent transportation system communications involving transit. Citations will not be limited, however, to rural activities, or to ITS implementation, or even to transit. In addition, the term ''communication'' will be broadly applied to include all information resources. Literature references to issues that contribute to both successful and failed efforts at sharing communication resources are reviewed. The findings of this literature review indicate that: (1) The most frequently shared communication resources are information/data resources, (2) Telecommunications infrastructure and technologies are the next most frequently shared resources, (3) When resources are successfully shared, all parties benefit, (4) A few unsuccessful attempts of sharing resources have been recorded, along with lessons learned, (5) Impediments to sharing include security issues, concerns over system availability and reliability, service quality and performance, and institutional barriers, (6) Advantages of sharing include financial benefits to agencies from using shared resources and benefits to the public in terms of congestion mitigation, information transfer (e.g., traveler information systems), mobility (e.g., welfare-to-work paratransit), and safety (e.g., speed of incident response, incident avoidance), (7) Technology-based solutions exist to address technology-based concerns, and (8) Institutional issues can be addressed through leadership, enhanced knowledge and skills, open communication, responsiveness, and attractive pricing structures.

Use of New Communication Technologies to Change NASA Safety Culture: Incorporating the Use of Blogs as a Fundamental Communications Tool

Science.gov (United States)

Huls, Dale Thomas

2005-12-01

Blogs are an increasingly dominant new communication function on the internet. The power of this technology has forced media, corporations and government organizations to begin to incorporate blogging into their normal business practices. Blogs could be a key component to overcoming NASA's "silent safety culture." As a communications tool, blogs are used to establish trust primarily through the use of a personal voice style of writing. Dissenting voices can be raised and thoroughly vetted via a diversity of participation and experience without peer pressure or fear of retribution. Furthermore, the benefits of blogging as a technical resource to enhance safety are also discussed. The speed and self-vetting nature of blogging can allow managers and decision-makers to make more informed and therefore potentially better decisions with regard to technical and safety issues. Consequently, it is recommended that NASA utilize this new technology as an agent for cultural change.

Biometric Methods for Secure Communications in Body Sensor Networks: Resource-Efficient Key Management and Signal-Level Data Scrambling

Science.gov (United States)

Bui, Francis Minhthang; Hatzinakos, Dimitrios

2007-12-01

As electronic communications become more prevalent, mobile and universal, the threats of data compromises also accordingly loom larger. In the context of a body sensor network (BSN), which permits pervasive monitoring of potentially sensitive medical data, security and privacy concerns are particularly important. It is a challenge to implement traditional security infrastructures in these types of lightweight networks since they are by design limited in both computational and communication resources. A key enabling technology for secure communications in BSN's has emerged to be biometrics. In this work, we present two complementary approaches which exploit physiological signals to address security issues: (1) a resource-efficient key management system for generating and distributing cryptographic keys to constituent sensors in a BSN; (2) a novel data scrambling method, based on interpolation and random sampling, that is envisioned as a potential alternative to conventional symmetric encryption algorithms for certain types of data. The former targets the resource constraints in BSN's, while the latter addresses the fuzzy variability of biometric signals, which has largely precluded the direct application of conventional encryption. Using electrocardiogram (ECG) signals as biometrics, the resulting computer simulations demonstrate the feasibility and efficacy of these methods for delivering secure communications in BSN's.

Communication Schemes with Constrained Reordering of Resources

DEFF Research Database (Denmark)

Popovski, Petar; Utkovski, Zoran; Trillingsgaard, Kasper Fløe

2013-01-01

This paper introduces a communication model inspired by two practical scenarios. The first scenario is related to the concept of protocol coding, where information is encoded in the actions taken by an existing communication protocol. We investigate strategies for protocol coding via combinatorial...... reordering of the labelled user resources (packets, channels) in an existing, primary system. However, the degrees of freedom of the reordering are constrained by the operation of the primary system. The second scenario is related to communication systems with energy harvesting, where the transmitted signals...... are constrained by the energy that is available through the harvesting process. We have introduced a communication model that covers both scenarios and elicits their key feature, namely the constraints of the primary system or the harvesting process. We have shown how to compute the capacity of the channels...

Challenges of communicating integrated water resource management in Zimbabwe

Science.gov (United States)

Marimbe, Simbiso; Manzungu, Emmanuel

With the promulgation of the 1998 Water Act the Government of Zimbabwe took a decisive step to reform the country’s water sector, to bring it in line with contemporary socio-political realities obtaining in the country, and in tune with the philosophy of integrated water resources management. Researchers have reported a lack of awareness of the reforms, particularly among the black communities, who were considered not just as one of the target of the reforms, but the beneficiaries. This paper analyses why this has been the case. The paper makes a case for differentiating communication from information dissemination. Information refers to a set of data packaged for delivery to a receiver while communication involves a dialogue. This paper critiques communication strategies used to communicate water reforms in Zimbabwe, applying recent developments in communication theories. The argument in the paper is that there was a failure to communicate although there was some success in dissemination information about the reforms. If the situation is to be reversed then methods that involve audience analysis may have to be used. Such methods tend to be expensive and time consuming--however, there is no substitute to this if integrated water resources management is to be institutionalised among the various stakeholders.

Technology adoption in nonrenewable resource management

International Nuclear Information System (INIS)

Cunha-e-Sa, Maria A.; Balcao Reis, Ana; Roseta-Palma, Catarina

2009-01-01

Technological change has played an important role in models of nonrenewable resource management, since its presence mitigates the depletion effect on extraction costs over time. We formalize the problem of a competitive nonrenewable resource extracting firm faced with the possibility of technology adoption. Based on a quadratic extraction cost function, our results show that the expected net benefits from adoption increase both with the size of the resource stock and with prices. A boundary that separates the region where expected net benefits are positive from the one where they are negative is derived. (author)

2017-01-01

Optical wireless communications (OWC) in general and resource allocation in OWC networks particularly have gained lots of attention recently. In this work, we consider the resource allocation problem of a visible light communication downlink transmission system based on time division multiple access with the objective of maximizing spectral efficiency (SE). As for the operational conditions, we impose constraints on the average optical intensity, the energy consumption and the quality-of-service. To solve the non-convex problem, we transform the objective function into a difference of concave functions by solving a second order differential inequality. Then, we propose a low-complexity algorithm to solve the resource allocation problem. Finally, we show by simulations the SE performance gains achieved by optimizing the power allocation over equal power allocation in the considered system. Numerical results show the SE gains achieved by using this solution.

Critical issues in the choice of appropriate communication technology by Third World countries.

Science.gov (United States)

Sonaike, S A

1987-01-01

Recent experience suggests that the most appropriate form of technology for the Third World is an adapted, intermediate (less capital intensive) technology, founded around the needs of the people and utilizing readily available resources. When technology is used to relieve the symptoms of underdevelopment, a technologic misfit manifested in an overemphasis on prestige projects and the urban industrial sector results. Advanced communication technologies such as satellites are generally capital intensive, require high technical skills to install and maintain, and need sophisticated levels of management to function properly. These conditions are not easily met in the Third World, underscoring the need for intermediate technology as manifested in small and medium-sized business enterprises. Such an approach blends traditional technology, minimal capital, simple management structure, ample labor, and humane operation with the gains from sophisticated technology. Intermediate technology can serve as a good training ground for indigenous people in modern business methods and provide jobs for the unemployed. Most importantly, intermediate technology can function as an integral part of the larger society rather than as a loosely attached appendage grafted on by some foreign country. In the field of communication, such an approach would manifest itself in a willingness to operate professionally with simple portable cameras, an acceptance of the importance of rural radio broadcasting and village newspapers, a willingness on the part of trained media professionals to try out locally produced hardware, and an exploration of cheaper ways of producing textbooks.

Effective communication with patients is essential to quality care. Obviously, language barriers significantly impact this and can increase the risk of poor patient outcomes. Smartphones and mobile health technology are valuable resources that are beginning to break down language barriers in health care. We present a case of a challenging language barrier where successful perioperative communication was achieved using mobile technology. Although quite beneficial, use of technology that is not validated exposes providers to unnecessary medicolegal risk. We hope to highlight the need for validation of such technology to ensure that these tools are an effective way to accurately communicate with patients in the perioperative setting.

Goldie, T. [Hydro One Networks Inc., Toronto, ON (Canada); Hodder, S. [GE Digital Energy, Toronto, ON (Canada)

2008-07-01

The challenges facing electric utilities regarding a shortage of highly qualified labour to maintain, refurbish and expand electrical infrastructure can be attributed to a wave of retirements in skilled employees, a shortage of entry-level workers and a rapidly increasing workload caused by investment in electricity infrastructure. Two solutions were presented for finding and sustaining an adequate personnel base. The first involved developing local talent, both entry-level and mid-career staff to ensure that work continuity and workplace safety are maintained. The second involved the implementation of technological solutions to help optimize the use of existing and future labour resources. This paper presented the human resource programs developed by Hydro One, the largest electrical transmission and distribution utility in the province of Ontario. Their initiatives include raising the profile of the utility work environment through strategic partnerships with educational institutions and developing in house offerings to supplement existing academic programs. This paper also presented a technical solution to address the resources challenges specifically associated with power system protection and control. The solution targets professional and skilled trades involved in the design, installation and maintenance of automated substations and protection and control systems. It is based on the premise that resource optimization can be achieved by reducing inconsistent design and construction practices and replacing these designs with highly standardized materials with digital communications using IEC 61850. This new technology should attract young professionals to the power engineering field while still maintaining a high comfort level with the established professional workforce. 5 refs., 4 figs.

Wilburn, David R.; Goonan, Thomas G.; Bleiwas, Donald I.

2001-01-01

The specter of mineral resource scarcity has been repeatedly raised as a concern because ever-growing populations with seemingly insatiable appetites for minerals place claims against a finite resource endowment. This report analyzes how technology has helped to ease resource constraints, and uses case studies of aluminum, copper, potash, and sulfur minerals to identify the effects of technology on resource supply. In spite of heightened demand for and increased loss of resources to environmental policy and urbanization, mineral producers historically have been able to continually expand production and lower costs. Specific production increases for the years 1900-98 were: aluminum (3,250 percent), copper (2,465 percent), potash (3,770 percent), and sulfur (6,000 percent). For the same period, constant-dollar (1998) prices decreased: aluminum (90 percent), copper (75 percent), potash (94 percent), and sulfur (89 percent). The application of technology has made available mineral deposits that were previously overlooked or considered non-viable. Using technology, producers can meet the demand for stronger, energy-efficient, more environmentally safe products with less physical material. Technologies have been developed to increase the amount of materials recycled and remanufactured. Technology development can occur in breakthroughs, but most often advances incrementally. Technological development is driven by the profit motive.

Wu, Robert C; Tran, Kim; Lo, Vivian; O'Leary, Kevin J; Morra, Dante; Quan, Sherman D; Perrier, Laure

2012-11-01

To conduct a systematic review of the literature to identify, describe and assess interventions of information and communication technology on the processes of communication and associated patient outcomes within hospital settings. Studies published from the years 1996 to 2010 were considered and were selected if they described an evaluation of information and communication technology interventions to improve clinical communication within hospitals. Two authors abstracted data from full text articles, and the quality of individual articles were appraised. Results of interventions were summarized by their effect. There were 18 identified studies that evaluated the use of interventions that included alphanumeric paging, hands-free communication devices, mobile phones, smartphones, task management systems and a display based paging system. Most quantitative studies used a before and after study design and were of lower quality. Of all the studies, there was only one prospective randomized study, but this study used only simulated communication events. Quantitative studies identified improved perceptions of communication and some improvement in communication metrics. Qualitative studies described improvements in efficiency of communication but also issues of loss of control and reliability. Despite the rapid advancement in information and communications technology over the last decade, there is limited evidence suggesting improvements in the ability of health professionals to communicate effectively. Given the critical nature of communication, we advocate further evaluation of information and communication technology designed to improve communication between clinicians. Outcome measures should include measures of patient-oriented outcomes and efficiency for clinicians. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Use of technology-based interventions to reduce dependence among persons with disability would be beneficial, both socially and economically, in developing countries with limited resources.

Underground communications and tracking technology advances

Energy Technology Data Exchange (ETDEWEB)

Fiscor, S

2007-03-15

As the June 2009 deadline set by the MINER Act grows near, several technologies have emerged as possible options for communicating and tracking underground coal miners in the event of an emergency or disaster. NIOSH is currently deciding how best to invest $10 million assigned by Congress under an Emergency Supplementary Appropriations Act (ESA) to research and develop mine safety technology. Medium and ultra high frequency (UHF) systems seem to be leading the pack with radio frequency identification (RFID) tags serving as the tracking system. Wireless mesh systems can serve as a communications infrastructure and they can do much more. Even more technologies continue to emerge, such as inertial navigation tracking systems. Mines are discovering the wonders of modern voice and data communications underground. Still no one know if it is economically practical to design a system that will function after a coal mine explosion. From the nineteen systems submitted to MSHA's request for information (RFI), six systems were selected that represented most of the technologies that had been proposed: the Rajant Breadcrumb, Innovative Wireless, Concurrent Technologies/Time Domain, Transtek, Gamma Services, and the Kutta Consulting systems. They were tested at CONSOL Energy's McElroy mine in April 2006. MSHA felt that all of those systems needed a significant amount of work before they were ready for use in a underground coal mining environment. The agency continues to work with these, and other manufacturers, to assist in arranging for field demonstration and then to gain MSHA approval.

Sharing Service Resource Information for Application Integration in a Virtual Enterprise - Modeling the Communication Protocol for Exchanging Service Resource Information

Science.gov (United States)

Yamada, Hiroshi; Kawaguchi, Akira

Grid computing and web service technologies enable us to use networked resources in a coordinated manner. An integrated service is made of individual services running on coordinated resources. In order to achieve such coordinated services autonomously, the initiator of a coordinated service needs to know detailed service resource information. This information ranges from static attributes like the IP address of the application server to highly dynamic ones like the CPU load. The most famous wide-area service discovery mechanism based on names is DNS. Its hierarchical tree organization and caching methods take advantage of the static information managed. However, in order to integrate business applications in a virtual enterprise, we need a discovery mechanism to search for the optimal resources based on the given a set of criteria (search keys). In this paper, we propose a communication protocol for exchanging service resource information among wide-area systems. We introduce the concept of the service domain that consists of service providers managed under the same management policy. This concept of the service domain is similar to that for autonomous systems (ASs). In each service domain, the service information provider manages the service resource information of service providers that exist in this service domain. The service resource information provider exchanges this information with other service resource information providers that belong to the different service domains. We also verified the protocol's behavior and effectiveness using a simulation model developed for proposed protocol.

Development of information communications technologies that surpass the global communications network is being pushed forward in order to establish the global village that McLuhan foretold in 1964. Effects of hybrid intensification with the intensification of communications technologies and computer technologies have become evident as facsimiles, automated teller machines of banks, home videos, automatic response telephones with synthetic voices, compact disks, portable telephones, video games and high-definition televisions were developed and put to use in a wide range. Intensification and integration of computer technologies and communications technologies has every possibility, but it also has a peculiar aspect of lacking guiding principles. Uncertain factors of the values of informations in the market are ever increasing, and their true values are yet to be found. Anyhow, it is a long way to the goal of the global village.

"Apping Up": Prospects for Information Technology Innovation in Return to Work Communication.

Singh, Ripdaman; O'Hagan, Fergal

2018-03-21

Purpose During return to work (RTW), communication between health care providers and employers largely takes place through standardize paper-based forms. Information technology (IT) platforms may provide advantages in enabling information exchange and decision-making through sharing of guidelines and resources. We investigated stakeholder perspectives on the prospect of IT use for RTW communication in Ontario, Canada. Methods Consistent with the exploratory nature of the questions, qualitative methods were used. Primary data were interviews with health care providers (HCPs), employers, and workers with experience in RTW. The first portion of initial interviews elicited general perspectives and experiences related to RTW communication. Participants were then exposed to a prototype IT communication platform and elicited their feedback. Follow-up interviews with HCP's and EMP's were used to allow further reflection and clarification of data. We used progressive, thematic coding to analyze data. Results 12 HCPs, 7 employers, and 5 workers participated in the study. Five inter-related themes were obtained. Participants expressed no absolute objection to the use of IT for RTW communication but varying degrees of support. Participants revealed how media change depended on a prospective IT innovation's perceived usefulness, fit with current practices, capacity to gain buy-in from other stakeholders, and ability to demonstrate positive performance in actual practice. Conclusions Findings suggest that a transition to an IT-mediated tool for RTW communication is supported in principle; however, major caveats exist in relation to perceived value and fit with stakeholder practice. System support and stakeholder cooperation are likely necessary to adopt the change, yet IT-mediated communication has yet to demonstrate value. To avoid circularity, proof of principal needs to be established through an implementation trial of such technology.

The right to get a proper education for every citizen had been regulated by the government, but not all citizens have the same opportunity. This is due to the other factors in the nation's infrastructure, Frontier, Outermost, and Disadvantaged (3T) which have not beenaccomodatedto access information and communication technology (ICT), and the ideal learning environment in order to pursue knowledge. This condition could be achieved by reforming higher education. Such reforms include the provision of educational services in the form of a flexible learner-oriented, and to change the curriculum with market based.These changes would include the provision of lecturers, professors, and professional teaching force. Another important effort is to update the quality of higher education with resource utilization. This paper proposes a new education business model to realize the Smart Education (SE), with an orientation on the proven skills and competitive.SE is the higher education system to optimize output (outcome) learning with combine individual learning and collaboration techniques based network system, informal practice learning and formal theory. UtilizingICT resources can improve the quality and access to higher education in supporting activities of higher education.This paper shows that ICT resources can support virtual connected with the use of shared resources, such as resource of information, learning resources, computing resources, and human resources.

The National Climate Assessment as a Resource for Science Communication

Science.gov (United States)

Somerville, R. C. J.

2014-12-01

The 2014 Third National Climate Assessment (NCA3) is scientifically authoritative and features major advances, relative to other assessments produced by several organizations. NCA3 is a valuable resource for communicating climate science to a wide variety of audiences. Other assessments were often overly detailed and laden with scientific jargon that made them appear too complex and technical to many in their intended audiences, especially policymakers, the media, and the broad public. Some other assessments emphasized extensive scientific caveats, quantitative uncertainty estimates and broad consensus support. All these attributes, while valuable in research, carry the risk of impeding science communication to non-specialists. Without compromising scientific accuracy and integrity, NCA3 is written in exceptionally clear and vivid English. It includes outstanding graphics and employs powerful techniques aimed at conveying key results unambiguously to a wide range of audiences. I have used NCA3 as a resource in speaking about climate change in three very different settings: classroom teaching for undergraduate university students, presenting in academia to historians and other non-scientists, and briefing corporate executives working on renewable energy. NCA3 proved the value of developing a climate assessment with communication goals and strategies given a high priority throughout the process, not added on as an afterthought. I draw several lessons. First, producing an outstanding scientific assessment is too complex and demanding a task to be carried out by scientists alone. Many types of specialized expertise are also needed. Second, speaking about science to a variety of audiences requires an assortment of communication skills and tools, all tailored to specific groups of listeners. Third, NCA3 is scientifically impeccable and is also an outstanding example of effective communication as well as a valuable resource for communicators.

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

Purpose The purpose of this paper is to explore a non-technical overview for leaders and researchers about how to use a communications perspective to better assess, design and use digital health technologies (DHTs) to improve healthcare performance and to encourage more research into implementation and use of these technologies. Design/methodology/approach Narrative overview, showing through examples the issues and benefits of introducing DHTs for healthcare performance and the insights that communications science brings to their design and use. Findings Communications research has revealed the many ways in which people communicate in non-verbal ways, and how this can be lost or degraded in digitally mediated forms. These losses are often not recognized, can increase risks to patients and reduce staff satisfaction. Yet digital technologies also contribute to improving healthcare performance and staff morale if skillfully designed and implemented. Research limitations/implications Researchers are provided with an introduction to the limitations of the research and to how communications science can contribute to a multidisciplinary research approach to evaluating and assisting the implementation of these technologies to improve healthcare performance. Practical implications Using this overview, managers are more able to ask questions about how the new DHTs will affect healthcare and take a stronger role in implementing these technologies to improve performance. Originality/value New insights into the use and understanding of DHTs from applying the new multidiscipline of communications science. A situated communications perspective helps to assess how a new technology can complement rather than degrade professional relationships and how safer implementation and use of these technologies can be devised.

Nuclear technology helps to improve the quality of our everyday life. Nevertheless, there is still great misinformation and the issue divides public opinion. Several surveys were conducted over the past years to study public acceptance of Nuclear Technology in Brazil and worldwide. GlobeScan (2005), for the International Atomic Energy Agency (IAEA), and Eurobarometers (2010), published by the Nuclear Energy Agency (NEA) and the Organization for Economic Co-operation and development (OECD), report similar socio-demographic trends: the higher the education level, the more favorable is public opinion towards nuclear power. Taking into account education and communication are crucial to increase public knowledge and understanding of the benefits of Nuclear Technology and that Internet access has increased strongly all over the country, this educational project aims to take advantage of the potential of Information and Communication Technology (ICT) to disseminate the peaceful use of nuclear technology and its benefits, informing children and teenagers, as well as parents and teachers, who are most often unaware of the matter. Whereas Internet access has increased strongly for both public and private schools all over the country, this web-based educational project, entitled Radioatividades (Radioactivities), provides short courses, curiosities and interactive activities covering topics related to Nuclear Technology and its beneficial applications in several areas, such as medicine, agriculture, industry, art and electric power generation. The project uses the combination of multiple technologies and last generation internet resources. Our target is the dissemination of information, promoting the benefits of Nuclear Technology for new generations, contributing to public acceptance of Nuclear Technology, combating misinformation in our society, omission of the media and knowledge fragmentation.

Communicative social capital and collective efficacy as determinants of access to health-enhancing resources in residential communities.

Science.gov (United States)

Matsaganis, Matthew D; Wilkin, Holley A

2015-04-01

This article contributes to the burgeoning literature on the social determinants of health disparities. The authors investigate how communication resources and collective efficacy, independently and in combination, shape residents' access to health enhancing resources (including healthcare services, sources of healthier food options, and public recreation spaces) in their communities. Using random digit dial telephone survey data from 833 residents of South Los Angeles communities the authors show that communicative social capital-that is, an information and problem-solving resource that accrues to residents as they become more integrated into their local communication network of neighbors, community organizations, and local media-plays a significant role in access to health resources. This relationship is complicated by individuals' health insurance and health status, as communicative social capital magnifies the sense of absence of resources for those who are in worse health and lack insurance. Communicative social capital builds collective efficacy, which is positively related to access to health-enhancing resources, but it also mediates the negative relationship between communicative social capital and access to health resources. Residents with richer stores of communicative social capital and collective efficacy report better access to health resources. The authors conclude with a discussion of implications of these findings and suggestions for future research.

The relationship between the external environment and physician e-mail communication: The mediating role of health information technology availability.

Science.gov (United States)

Mazurenko, Olena; Hearld, Larry R; Menachemi, Nir

Physician e-mail communication, with patients and other providers, is one of the cornerstones of effective care coordination but varies significantly across physicians. A physician's external environment may contribute to such variations by enabling or constraining a physician's ability to adopt innovations such as health information technology (HIT) that can be used to support e-mail communication. The aim of the study was to examine whether the relationship of the external environment and physician e-mail communication with patients and other providers is mediated by the practice's HIT availability. The data were obtained from the Health Tracking Physician Survey (2008) and the Area Resource File (2008). Cross-sectional multivariable subgroup path analysis was used to investigate the mediating role of HIT availability across 2,850 U.S. physicians. Solo physicians' perceptions about malpractice were associated with 0.97 lower odds (p communication with patients and other providers, as compared to group and hospital practices, even when mediated by HIT availability. Subgroup analyses indicated that different types of practices are responsive to the different dimensions of the external environment. Specifically, solo practitioners were more responsive to the availability of resources in their environment, with per capita income associated with lower likelihood of physician e-mail communication (OR = 0.99, p information technology availability, which in turn was associated with a greater likelihood of communicating via e-mail with patients (OR = 1.02, p communication and the external environment is mediated by the practice's HIT availability. Efforts to improve physician e-mail communication and HIT adoption may need to reflect the varied perceptions of different types of practices.

To gain insights into how technological communication tools impact effective communication among clinicians, which is critical for patient safety. This multi-site observational study analyzes inter-clinician communication and interaction with information technology, with a focus on the critical process of patient transfer from the Emergency Department to General Internal Medicine. Mount Sinai Hospital, Sunnybrook Health Sciences Centre and Toronto General Hospital. At least five ED and general internal medicine nurses and physicians directly involved in patient transfers were observed on separate occasions at each institution. N/A. N/A. The study provides insight into clinician workflow, evaluates current hospital communication systems and identifies key issues affecting communication: interruptions, issues with numeric pagers, lack of integrated communication tools, lack of awareness of consultation status, inefficiencies related to the paper chart, unintuitive user interfaces, mixed use of electronic and paper systems and lack of up-to-date contact information. It also identifies design trade-offs to be negotiated: synchronous communication vs. reducing interruptions, notification of patient status vs. reducing interruptions and speed vs. quality of handovers. The issues listed should be considered in the design of new technology for hospital communications. © The Author 2015.

Full Text Available There is no questioning that the way people live, interact, communicate, and conduct business is undergoing a profound, rapid change. This change is often referred to as the “digital revolution,” which is the advancement of technology from analog, electronic and mechanical tools to the digital tools available today. Moreover, technology has begun to change education, affecting how students acquire the skill sets needed to prepare for college and a career and how educators integrate digital technological instructional strategies to teach. Numerous studies have been published discussing the barriers of integrating technology, the estimated amount of investment that is needed in order to fully support educational technology, and, of course, the effectiveness of technology in the classroom. As such, this article presents a critical review of the transitions that technology integration has made over the years; the amount of resources and funding that has been allocated to immerse school with technology; and the conflicting results presented on effectiveness of using is technology in education. Through synthesis of selected themes, we found a plethora of technological instructional strategies being used to integrate technology into K-12 classrooms. Also, though there have been large investments made to integrate technology into K-12 classrooms to equip students with the skills needed to prepare for college and a career, the practical use of this investment has not been impressive. Lastly, several meta-analyses showed promising results of effectiveness of technology in the classroom. However, several inherent methodological and study design issues dampen the amount of variance that technology accounts for.

2011-10-01

Mobile communication technologies are employed in many diverse areas of healthcare delivery to provide improved quality and efficiency of communication and facilitate increased rapidity of data or information transfer. Mobile phones enable healthcare professionals to possess a portable platform from which to provide many healthcare-related applications and are a popular means to directly communicate with colleagues and patients. As involvement of mobile communication technology in healthcare delivery continues to rapidly expand, there are also important considerations of relevance to patient safety and security as a result. Here, we review the previous evidence of reported clinical risks associated with mobile communication technology, such as electromagnetic interference, confidentiality and data security, distraction/noise, infection control, and cross contamination. In conclusion, although mobile phones provide much putative potential improvement to healthcare delivery, further evaluation and research are required to both inform and protect health professionals and users of such technology in the healthcare environment and provide the evidence base to support the provision of clear and comprehensive guidelines.

Integrative Technologies Complicate Communication during Development Work Context: Industry-Academy Collaboration

Directory of Open Access Journals (Sweden)

Pauliina Mansikkamäki

2007-06-01

Full Text Available A competition in the electronics industry is hard. For most companies, strong technological know-how will be a competitiveness factor in the future. The future technologies will be increasingly based on a combination of innovations from several branches of science. Also, many innovations are based on external technology integration. The days are over when one company could internally create all of the technology it needs to maintain its competitiveness. One approach of promising framework for the development of a new integrative technology is an industrial R&D network combined with industrial-academic collaboration. However, this kind of collaboration is a challenging undertaking. Companies in a value network might have very different expectations regarding a new technology due to differences in their position in the value network or their company strategy. One of the main challenges in an R&D network is to translate the expectations of all parties involved into new technology solutions so that all in the R&D network feel they have obtained benefit. One of key factors on creating successful industrial-academic collaboration is open and trustful communication. But, there are communication challenges, intellectual property sharing problems, and discussions regarding the sharing of cost and benefits. Developing a new integrative technology structure requires seamless teamwork, holistic and interdisciplinary understanding, and open communication throughout the R&D team and the industrial-academic network. The focus of this paper is on network communication, knowledge communication and team communication. The results of this study indicate that successful communication in an industrial-academic R&D network to develop a new integrative technology improves knowledge creation and accelerates commercialization of the technology.

How to assess the availability of resources for new technologies? Case study: lithium a strategic metal for emerging technologies

International Nuclear Information System (INIS)

Weil, M.; Ziemann, S.; Schebek, L.

2009-01-01

The development of new technologies is often connected with the use of non-renewable resources. In recent years a qualitative shift in the demand of bulk metals (e.g. Fe, Al, Cu) to more scarce metals (e.g. Te, Ga, Re) is recognizable. Novel technologies and products rely more and more on very specific metals which are indispensable for their function. Although such metals are generally used in low concentrations in products, the demand has raised significantly due to mass production. Some of them are of high importance due to their strategic relevance to emerging innovative technologies. Lithium so far has gained relatively little attention, although it fulfills the main criteria of a strategically relevant metal. In recent years, however, recognition of lithium increased as a result of the growing market for lithium-based chargeable batteries in mobile information/communication consumer products and in electric vehicles. Both areas of demand led to a skyrocketed use of lithium in recent years. Other technologies in the future like fusion power generation will raise lithium consumption at an accelerated rate. It is therefore necessary to determine the availability of lithium in the medium and long term in order to prevent technology failures and to ensure a more sustainable development. The authors will provide a well founded knowledge base, outline the availability of worldwide reserves and resources, and describe the structure of present and future demands for lithium. (authors)

Communication technologies and emotionality in transnational families

Directory of Open Access Journals (Sweden)

María Guadalupe Ramírez Contreras

2014-07-01

Full Text Available It was estimated in 2009 that 11,500.0 millions Mexican immigrants were living in the United States (Pew Hispanic Center, 2009. However, such immigrants can’t take their families with them to the US breaking-up of the family unit. Therefore, immigrants and their families become members of a transnational family.  In order to cope with such family break-up, members of such families try to balance themselves through developing an emotional intimacy using communication technologies. However, what kind of emotional support is offered when one of the members of the transnational family is a senior citizen and chronically ill? What kind of emotions do these transnational families experience? Which communication technologies do they use to be in touch? How these communication technologies are related to the emotional support? In order to answer these research questions, I explored previous studies in which I found that they only included the immigrants’ point of view. To overcome this limitation in this study, I included the point of view of all members of transnational families. I conducted a qualitative study. It took place in Sahuayo, Michoacan. I interviewed members of 15 transnational families during 2012 and 2013. The results showed that emotional support was identified as: a contacting relatives in Mexico, initiated by immigrants, b exchanging daily life experiences; c solving issues and conflicts; and d immigrants supporting, participating or being virtually in special celebrations. Immigrants also used communication technologies in order to maintain emotional ties and give emotional support to their parents. The communication help immigrants to provide the emotional support to their parents and also to express their feelings. I recommend studying national migrants and rural populations, in order to analyse any differences between them and my sample.

Improving clinical communication of students with English as a second language (ESL) using online technology: a small scale evaluation study.

Science.gov (United States)

Rogan, Fran; San Miguel, Caroline

2013-09-01

Increasingly, students with English as a second language (ESL) are enrolled in nursing degrees in English speaking countries (Wang et al., 2008). However, they may be at risk of clinical practice failure due to communication difficulties associated with unfamiliar linguistic and cultural factors (Guhde, 2003). This paper describes and evaluates an innovation to assist ESL nursing students at an Australian university develop their clinical communication skills and practice readiness by providing online learning resources, using podcast and vodcast technology, that blend with classroom activities and facilitate flexible and independent learning. The innovation builds on an intensive clinical language workshop program called 'Clinically Speaking' which has evolved through a cyclical process of ongoing research to produce resources in response to students' learning needs. Whilst uptake of the resources was modest, students of ESL as well as English speaking backgrounds (ESB) found the resources improved their clinical preparation and confidence by increasing their understanding of expectations, clinical language and communication skills. The innovation, developed with a modest budget, shows potential in developing ESL and ESB students' readiness for clinical communication, enabling them to engage in clinical practice to develop competency standards required of nursing graduates and registration authorities.

To report on the relationship between competence and confidence in nursing students as users of information and communication technologies, using principal components analysis. In nurse education, learning about and learning using information and communication technologies is well established. Nursing students are one of the undergraduate populations in higher education required to use these resources for academic work and practice learning. Previous studies showing mixed experiences influenced the choice of an exploratory study to find out about information and communication technologies competence and confidence. A 48-item survey questionnaire was administered to a volunteer sample of first- and second-year nursing students between July 2008-April 2009. The cohort ( N  =   375) represented 18·75% of first- and second-year undergraduates. A comparison between this work and subsequent studies reveal some similar ongoing issues and ways to address them. A principal components analysis (PCA) was carried out to determine the strength of the correlation between information and communication technologies competence and confidence. The aim was to show the presence of any underlying dimensions in the transformed data that would explain any variations in information and communication technologies competence and confidence. Cronbach's alpha values showed fair to good internal consistency. The five component structure gave medium to high results and explained 44·7% of the variance in the original data. Confidence had a high representation. The findings emphasized the shift towards social learning approaches for information and communication technologies. Informal social collaboration found favour with nursing students. Learning through talking, watching and listening all play a crucial role in the development of computing skills.

A Fair Resource Allocation Algorithm for Data and Energy Integrated Communication Networks

Directory of Open Access Journals (Sweden)

Qin Yu

2016-01-01

Full Text Available With the rapid advancement of wireless network technologies and the rapid increase in the number of mobile devices, mobile users (MUs have an increasing high demand to access the Internet with guaranteed quality-of-service (QoS. Data and energy integrated communication networks (DEINs are emerging as a new type of wireless networks that have the potential to simultaneously transfer wireless energy and information via the same base station (BS. This means that a physical BS is virtualized into two parts: one is transferring energy and the other is transferring information. The former is called virtual energy base station (eBS and the latter is named as data base station (dBS. One important issue in such setting is dynamic resource allocation. Here the resource concerned includes both power and time. In this paper, we propose a fair data-and-energy resource allocation algorithm for DEINs by jointly designing the downlink energy beamforming and a power-and-time allocation scheme, with the consideration of finite capacity batteries at MUs and power sensitivity of radio frequency (RF to direct current (DC conversion circuits. Simulation results demonstrate that our proposed algorithm outperforms the existing algorithms in terms of fairness, beamforming design, sensitivity, and average throughput.

Resource recycling as new field for innovative technologies

Directory of Open Access Journals (Sweden)

Kamenik L.L.

2017-01-01

Full Text Available This study substantiates the necessity of transition from the natural resource model of socioeconomic development towards an industrially reproducible type of raw material, which is particularly relevant in the context of the global resource crisis. The key role of innovative technologies in the solution to this problem is questioned. Theoretical and methodological principles of the modern economy functioning are examined based on the resource factor. A new concept of “resource recycling”, which reflects industrial resource recovery, is introduced. An innovative model of a resource base for economic reproduction is provided, the necessity of transition from the existing linear economic model towards a closed resource cycle model is shown, and three resource cycle models are examined in terms of their objectives, forms, and content. The major problems in the implementation of the innovative model and ways of solving them are defined, which makes it possible to reduce the risk of a resource provision crisis. The conclusion that resource recycling serves as a new sphere of innovative technologies is substantiated. The historical analogy method and the evolutionary systems approach are used.

International Nuclear Information System (INIS)

Tsuchiya, Tomoko

2003-01-01

Although the importance of risk communication has been pointed out over the last decade in nuclear community, both public authorities and nuclear industry have not conducted the definite actions yet. It will be reflected in the public eye that nuclear community's attitude toward communication and consultation with the public about risk issues is half-hearted, comparing with chemical and food safety fields which recently launched their risk communication activities. In this study, we conduct risk communication experiments on some risk issues associated with nuclear technology and its utilization in Tokai village, for the purpose of establishment of risk communication in our society that might be one of the new relationships between science and technology and society. The outcomes of FY2002 study are the following threefold; 1) preparation of risk communication experiments on nuclear technology and its utilization, 2) assessment of social effects of risk communication activities, 3) preparation of practical guidebook for risk communication experiments.

Medical education for rural areas: Opportunities and challenges for information and communications technologies

Directory of Open Access Journals (Sweden)

Sargeant Joan

2005-01-01

Full Text Available Resources in medical education are not evenly distributed and access to education can be more problematic in rural areas. Similar to telemedicine′s positive influence on health care access, advances in information and communications technologies (ICTs increase opportunities for medical education. This paper provides a descriptive overview of the use of ICTs in medical education and suggests a conceptual model for reviewing ICT use in medical education, describes specific ICTs and educational interventions, and discusses opportunities and challenges of ICT use, especially in rural areas. The literature review included technology and medical education, 1996-2005. Using an educational model as a framework, the uses of ICTs in medical education are, very generally, to link learners, instructors, specific course materials and/or information resources in various ways. ICTs range from the simple (telephone, audio-conferencing to the sophisticated (virtual environments, learning repositories and can increase access to medical education and enhance learning and collaboration for learners at all levels and for institutions. While ICTs are being used and offer further potential for medical education enhancement, challenges exist, especially for rural areas. These are technological (e.g., overcoming barriers like cost, maintenance, access to telecommunications infrastructure, educational (using ICTs to best meet learners′ educational priorities, integrating ICTs into educational programs and social (sensitivity to remote needs, resources, cultures. Finally, there is need for more rigorous research to more clearly identify advantages and disadvantages of specific uses of ICTs in medical education.

Miyoshi, Kazuhisa

Companies want more business-minded industrial technology managers and engineers with entrepreneurial skills who also have an awareness of the challenges of global marketplace. Both the Master of Engineering and Management Degree (MEM) and the Master of Management of Technology Degree (MOT) aim to meet the needs of industry by offering managers and engineers the critical skills need to be successful in a professional career. The world today is characterized by an ever-growing number of contacts resulting in communication between people in industry with different linguistic and cultural backgrounds. This communication takes place because of contacts within the areas of business, engineering, technology, science, and education but also because of immigration brought about by labor shortage or political conflicts. In all these contacts, there is communication, which needs to be as constructive as possible, without misunderstandings and breakdowns. Knowledge on the nature of linguistic and cultural similarities and differences can play a positive and constructive role. The objective of this paper is to examine what makes the difference in communication between people with diverse cultural background. In addition, it emphasizes the importance of diversity management and diversity leadership in the diverse workplace.

Nilsson, Carina; Skär, Lisa; Söderberg, Siv

2008-01-01

The use of information and communication technology has increased in the society, and can be useful in nursing care. The aim of this study was to describe district nurses' attitudes regarding the implementation of information and communication technology in home nursing. The first and third authors performed five focus group discussions with 19 district nurses' from five primary healthcare centres in northern Sweden. During the focus group discussions, the following topics were discussed: the current and future use of information and communication technology in home nursing; expectations, advantages, disadvantages and hindrances in the use of information and communication technology in home nursing; and the use of information and communication technology from an ethical perspective. The transcribed focus group discussions were analysed using qualitative content analysis. The results showed that district nurses' attitudes were positive regarding the use of information and communication technology in their work. They also asked for possibilities to influence the design and its introduction. However, the use of information and communication technology in home nursing can be described as a complement to communication that could not replace human physical encounters. Improvements and risks, as well as the importance of physical presence in home nursing were considered vital. The results revealed that the use of information and communication technology requires changes in the district nurses' work situation.

Nanotechnology risk perceptions and communication: emerging technologies, emerging challenges.

Science.gov (United States)

Pidgeon, Nick; Harthorn, Barbara; Satterfield, Terre

2011-11-01

Nanotechnology involves the fabrication, manipulation, and control of materials at the atomic level and may also bring novel uncertainties and risks. Potential parallels with other controversial technologies mean there is a need to develop a comprehensive understanding of processes of public perception of nanotechnology uncertainties, risks, and benefits, alongside related communication issues. Study of perceptions, at so early a stage in the development trajectory of a technology, is probably unique in the risk perception and communication field. As such it also brings new methodological and conceptual challenges. These include: dealing with the inherent diversity of the nanotechnology field itself; the unfamiliar and intangible nature of the concept, with few analogies to anchor mental models or risk perceptions; and the ethical and value questions underlying many nanotechnology debates. Utilizing the lens of social amplification of risk, and drawing upon the various contributions to this special issue of Risk Analysis on Nanotechnology Risk Perceptions and Communication, nanotechnology may at present be an attenuated hazard. The generic idea of "upstream public engagement" for emerging technologies such as nanotechnology is also discussed, alongside its importance for future work with emerging technologies in the risk communication field. © 2011 Society for Risk Analysis.

Wittenberg, Elaine; Goldsmith, Joy; Ferrell, Betty; Ragan, Sandra L

2017-07-01

Family caregivers of cancer patients have a vital role in facilitating and sharing information about cancer, revealing a need to develop caregiver health literacy skills to support caregiver communication. The goal of this study was to investigate caregiver print materials and develop and assess a new caregiver communication resource titled A Communication Guide for Caregivers TM . Using a model of six domains of caregiver health literacy skills, print cancer education materials were collected and evaluated for caregiver communication support. A new caregiver communication resource was also developed and assessed by caregivers and healthcare providers. Caregivers reviewed content and assessed utility, relatability, and reading quality. Healthcare providers also assessed whether the material would be understandable and usable for cancer caregivers. Only three of the 28 print materials evaluated were written at the recommended sixth grade reading level and only five addressed all six caregiver health literacy skills. Readability scores for A Communication Guide for Caregivers TM were at the sixth grade level, and caregivers reported its contents were relatable, useful, and easy to read. Healthcare providers also rated the material as easy for patient/family members of diverse backgrounds and varying levels of literacy to understand and use. Existing print-based caregiver education materials do not address caregivers' health literacy skill needs and are aimed at a highly literate caregiving population. A Communication Guide for Caregivers TM meets health literacy standards and family caregiver and provider communication needs. The findings are relevant for healthcare professionals who provide cancer education. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

We assemble our valve work ‘packages’ and print the resultant information for the technician in the field. At the point we hit print, we disconnect our technicians from that information and ourselves from their progress. Employing the paper copy, resources are tasked with the execution of complex valve work in the field. Cumbersome hand offs between stakeholders responsible for different processes jeopardize schedule adherence while front line supervisors attempt to keep everyone up to date, often removing them from a critical task. Occasionally these paper packages are lost or destroyed or found to be missing information, placing daily activities at risk. Leveraging information and communications technology in a Valve Program can significantly change how we operate. The technology exists to ensure field resources have the most up-to-date information. We can be auto-notified when crucial steps are completed, know in advance if additional resources are required or analyze the time it takes to complete critical evolutions. Quality can be improved lessening the need for expensive re-work, workface efficiency and general productivity can also greatly benefit. We can prevent ‘hold’ points from being missed; ensure the correct revision of a procedure is employed or accurately predict when other work can begin. All this accomplished without having our field staff redirect their focus to update management. Technology based tools are slowly moving into our powerhouses and its time we took advantage to properly manage our Valve Programs. (author)

The author has made efforts to establish risk communication in the nuclear industry since the JCO criticality accident. Some people understood the importance and the usefulness of risk communication both for local residents and their own business. Others, however, thought it troublesome, costly, and useless for their organization and nuclear safety. I think, unfortunately, experiences after the Fukushima accident force them to hesitate at communicating risks with the public more and more. I will discuss why and how risk communication of nuclear technology is difficult. (author)

An analysis of communications and networking technologies for the smart grid

Energy Technology Data Exchange (ETDEWEB)

Garcia Hernandez, Joaquin [Instituto de Investigaciones Electricas, Cuernavaca, Morelos (Mexico)

2013-03-01

The Smart Grid concept has been foreseen as the integration of the electrical generation, transmission and distribution network and the data communications network. Although, traditional communications interfaces, protocols and standards has been used in the electrical grid in an isolated manner, modern communications network is considered as the fundamental enabling technology within the future Smart Grid. Modern communications technologies, protocol architectures and standards can help to build a common communications network infrastructure for data transport between customer premises, power substations, and power distribution systems, utility control centers and utility data centers. The Smart Grid will support traditional applications such as SCADA, distribution automation (DA), energy management systems (EMS), demand site management (DSM) and automatic meter reading (AMR), etc., as well as new applications like advanced metering infrastructure (AMI), substation automation (SA), microgrids, distributed generation, grid monitoring and control, data storage and analysis, among others. To make this possible, the Smart Grid requires a two-way wide area communications network between different dispersed areas, from generation, to distribution to consumer premises. In fact, it will consist of many different types of communications networks such as wide area networks, local area network, home area networks, etc. This requires a new architectural approach to implement a common communications infrastructure that provides the reliability, scalability, security and interoperability to support multiple applications. In addition, open standards addressing interoperability, are key for the development and deployment of the Smart Grid as a true integrated network. A communications backbone is necessary to provide interoperability. To achieve the level of networking, interoperability and security that meets the technical requirements of the Smart Grid, its data communications

The Effect of Health Information Technology on Health Care Provider Communication: A Mixed-Method Protocol.

Communication failures between physicians and nurses are one of the most common causes of adverse events for hospitalized patients, as well as a major root cause of all sentinel events. Communication technology (ie, the electronic medical record, computerized provider order entry, email, and pagers), which is a component of health information technology (HIT), may help reduce some communication failures but increase others because of an inadequate understanding of how communication technology is used. Increasing use of health information and communication technologies is likely to affect communication between nurses and physicians. The purpose of this study is to describe, in detail, how health information and communication technologies facilitate or hinder communication between nurses and physicians with the ultimate goal of identifying how we can optimize the use of these technologies to support effective communication. Effective communication is the process of developing shared understanding between communicators by establishing, testing, and maintaining relationships. Our theoretical model, based in communication and sociology theories, describes how health information and communication technologies affect communication through communication practices (ie, use of rich media; the location and availability of computers) and work relationships (ie, hierarchies and team stability). Therefore we seek to (1) identify the range of health information and communication technologies used in a national sample of medical-surgical acute care units, (2) describe communication practices and work relationships that may be influenced by health information and communication technologies in these same settings, and (3) explore how differences in health information and communication technologies, communication practices, and work relationships between physicians and nurses influence communication. This 4-year study uses a sequential mixed-methods design, beginning with a

Full Text Available Research demonstrates the positive impact of parental involvement on students, families and schools. Studies also indicate a close connection between effective school-home communication and increased parental involvement and engagement in learning. Effective selection and use of Information Communication Technologies (ICT invites more effective school-home communication, increasing parental involvement and improving student outcomes. However, ICT adoption rates are heterogeneous, influenced by cultural, socioeconomic and other factors. Also, gaps may exist between parent/school communication preferences. Our multi-case study investigates principals and parents from three different public elementary schools (suburban/high wealth; urban/low wealth; urban magnet/mixed income to understand the impact of misalignment in ICT adoption and use on school-home communication. We find misperceptions by parents and principals regarding their ICT adoption beliefs and actual use. Our results also indicate alignment between parent and principal ICT preferences and expectations improves parent satisfaction with the principal and the school, while misalignment has the opposite effect.

System of Interactions of Social Actors in Public Communication of Science and Technology

Directory of Open Access Journals (Sweden)

Miriam Graciela Miquilena

2010-11-01

Full Text Available This paper presents the results of a research aimed at explaining the system of interactions of social actors in Public Communication of Science and Technology (PCST, in the context of a social web defined by the novel systems of communication sustained on informational and communication technologies. The study’s theoretical framework highlights the strategic importance of a Public Communication  which focuses on promoting public appropriation of Science and Technology, going beyond the role of Journalism and Science Communication that informs a qualified public, to one that stablishes a bond with policies and decision making in the area, made with participation of international agencies, governments, producers of science and technology, journalists’ associations, educational institutions, and citizens. The research relies on Explicative Methodology. A revision of pertinent bibliography leads to the conclusion that the system of social interactions mediated by personal, interpersonal and grupal global communications, define the relationships in the communicational exchange of the social actor with regard to public communication of science and technology and policies aimed at its appropriation.

Sävenstedt, Stefan; Sandman, P O; Zingmark, Karin

2006-10-01

The aim of this paper is to report a study illuminating values and perceptions held by professional carers of older people about the use of information and communication technology applications. Various information and communication technology applications have successfully been developed to help solve a variety of problems in elder care. Beside different technical barriers and the assumed negative attitudes among older people, staff values and attitudes have been found to be an important cause of resistance to change and slowness in introduction of information and communication technology in health care of older people. An interview study was conducted in 2004 with 10 healthcare personnel with 3-26 years experience of working in home care and nursing homes in Northern Sweden. Qualitative content analysis was used to identify recurring themes in the data. The interpretation of values and perceptions among carers revealed a duality where the carers perceived information and communication technology as a promoter of both inhumane and humane care, a duality that seemed to make them defensive and resistant to change. Within the overall duality, other dualities were embedded that described both perceptions about the care of older people and about being a carer. There was evidence of resistance among professional carers towards an introduction of information and communication technology applications in elder care. Carers considered that the same attributes of information and communication technology that could promote humane care could also lead to dehumanized care. There should be an ethical discussion when introducing information and communication technology applications in elder care. The best caring alternative for all those concerned should be considered. It should promote aspects of wellbeing and dignity for frail older people and fears of inhumane care among carers must be recognized and discussed.

Relationship behaviors contribute to compromised health or resilience. Everyday communication between intimate partners represents the vast majority of their interactions. When intimate partners take on new roles as patients and caregivers, everyday communication takes on a new and important role in managing both the transition and the adaptation to the change in health status. However, everyday communication and its relation to health has been little studied, likely due to barriers in collecting and processing this kind of data. The goal of this paper is to describe deterrents to capturing naturalistic, day-in-the-life communication data and share how technological advances have helped surmount them. We provide examples from a current study and describe how we anticipate technology will further change research capabilities. Copyright © 2017 Elsevier B.V. All rights reserved.

The dark side of technologies: technostress among users of information and communication technologies.

Science.gov (United States)

Salanova, Marisa; Llorens, Susana; Cifre, Eva

2013-01-01

This paper tests the structure and the predictors of two psychological experiences of technostress associated with the use of information and communication technologies (ICT), i.e., technostrain (users report feelings of anxiety, fatigue, scepticism and inefficacy beliefs related to the use of technologies) and technoaddiction (users feel bad due to an excessive and compulsive use of these technologies). The study included a sample of 1072 ICT users (N = 675 nonintensive ICT users and N = 397 intensive ICT users). Results from multigroup confirmatory factor analyses among non-intensive and intensive ICT users showed, as expected, the four-factor structure of technostrain in both samples. Secondly, and also as expected, confirmatory factorial analyses revealed that technostress experiences are characterized not only by technostrain but also by an excessive and compulsive use of ICT. Moreover, multiple analyses of variance showed significant differences between non-intensive and intensive ICT users (1) in the dimensions of technostress and (2) in specific job demands and job/personal resources. Finally, linear multiple regression analyses revealed that technostrain is positively predicted by work overload, role ambiguity, emotional overload, mobbing and obstacles hindering ICT use, as well as by lack of autonomy, transformational leadership, social support, ICT use facilitators and mental competences. Work overload, role ambiguity and mobbing, as well as the lack of emotional competences, positively predict technoaddiction. Theoretical and practical implications, in addition to future research, are discussed.

Bayramzadeh, Sara; Alkazemi, Mariam F

2014-01-01

This study aims to explore the relationship between the nursing station design and use of communication technologies by comparing centralized and decentralized nursing stations. The rapid changes in communication technologies in healthcare are inevitable. Communication methods can change the way occupants use a space. In the meantime, decentralized nursing stations are emerging as a replacement for the traditional centralized nursing stations; however, not much research has been done on how the design of nursing stations can impact the use of communication technologies. A cross sectional study was conducted using an Internet-based survey among registered nurses in a Southeastern hospital in the United States. Two units with centralized nursing stations and two units with decentralized nursing stations were compared in terms of the application of communication technologies. A total of 70 registered nurses completed the survey in a 2-week period. The results revealed no significant differences between centralized and decentralized nursing stations in terms of frequency of communication technologies used. However, a difference was found between perception of nurses toward communication technologies and perceptions of the use of communication technologies in decentralized nursing stations. Although the study was limited to one hospital, the results indicate that nurses hold positive attitudes toward communication technologies. The results also reveal the strengths and weaknesses of each nursing station design with regard to communication technologies. Hospital, interdisciplinary, nursing, technology, work environment.

Augmentative and alternative communication (AAC) systems were introduced into clinical practice by therapists to help compensate for persistent language deficits in people with aphasia. Although, there is currently a push towards an increased focus on compensatory approaches in an attempt to maximize communication function for social interaction, available studies including AAC systems, especially technologically advanced communication tools and systems, known as 'high-technology AAC', show key issues and obstacles for these tools to become utilized in mainstream clinical practice. Areas covered: The current review synthesizes communication intervention studies that involved the use of high-technology communication devices to enhance linguistic communication skills for adults with post-stroke aphasia. The review focuses on compensatory approaches that emphasized functional communication. It also summarizes recommendations for the report of studies evaluating high-technology devices that may be potentially relevant for other researchers working with adults with post-stroke aphasia. Expert commentary: Taken together with positive results in heterogeneous studies, high-technology devices represent a compensatory strategy to enhance communicative skills in individuals with post-stroke aphasia. Improvements in the design of studies and reporting of results may lead to better interpretation of the already existing scientific results from aphasia management.

Design principles for global commons: Natural resources and emerging technologies

Directory of Open Access Journals (Sweden)

Paul C. Stern

2011-09-01

Full Text Available Ostrom’s design principles for managing common pool resources were developed largely by examining local commons involving natural resources. This paper enumerates several key characteristics that distinguish such commons from more complex commons involving global resources and the risks of emerging technologies. It considers the degree to which the design principles transfer to those commons and concludes that although they have considerable external validity, the list needs some modification and elaboration to apply to global resources and risk commons. A list of design principles is offered for global resource commons and the risks of emerging technologies. Applying Ostrom’s approach to global resources and emerging technologies can improve understanding and expand the solution set for these problems from international treaties, top-down national regulation, and interventions in market pricing systems to include non-governmental institutions that embody principles of self-governance.

The authors discuss the problems in the communication of technological risks. They show that - contrary to a current popular belief - acceptance problems are not attributable to information deficits: such problems are caused rather by the fact that risks are perceived differently by the various groups in science, industry, politics and the larger public. Nevertheless, improved information about technology may help to find acceptable compromises and, thus, to prevent social conflicts to erupt over technology and to geopardize the basic political consensus.

Beck, Mary S; Doscher, Mindy

2018-04-01

The current study described RN and patient care technician (PCT) communication in centralized and hybrid decentralized workstation designs using hands-free communication technology and infrared locator badge technology to facilitate communication. New construction of an oncology unit provided the opportunity to compare staff communication in two different workstation designs. Observations and questionnaires compared nurse and PCT communication in the two-unit designs. Descriptive statistics were used to analyze the differences. The hybrid decentralized unit had increased use of hands-free communication technology and hallway communication by nurses and PCTs, and increased patient room communication by nurses. Perceptions of communication between nurses and PCTs and congruency of priorities for care were similar for both units. The locator badge technology had limited adoption. Replacement of nurse workstations with new construction or remodeling impact staff communication patterns, necessitating that nurse leaders understand the impact of design and technology on communication.

2003-01-01

In light of the events of September 11, 2001, NASA senior management requested an investigation of technologies and concepts to enhance aviation security. The investigation was to focus on near-term technologies that could be demonstrated within 90 days and implemented in less than 2 years. In response to this request, an internal NASA Glenn Research Center Communications, Navigation, and Surveillance Aviation Security Tiger Team was assembled. The 2-year plan developed by the team included an investigation of multiple aviation security concepts, multiple aircraft platforms, and extensively leveraged datalink communications technologies. It incorporated industry partners from NASA's Graphical Weather-in-the-Cockpit research, which is within NASA's Aviation Safety Program. Two concepts from the plan were selected for demonstration: remote "black box," and cockpit/cabin surveillance. The remote "black box" concept involves real-time downlinking of aircraft parameters for remote monitoring and archiving of aircraft data, which would assure access to the data following the loss or inaccessibility of an aircraft. The cockpit/cabin surveillance concept involves remote audio and/or visual surveillance of cockpit and cabin activity, which would allow immediate response to any security breach and would serve as a possible deterrent to such breaches. The datalink selected for the demonstrations was VDL Mode 2 (VHF digital link), the first digital datalink for air-ground communications designed for aircraft use. VDL Mode 2 is beginning to be implemented through the deployment of ground stations and aircraft avionics installations, with the goal of being operational in 2 years. The first demonstration was performed December 3, 2001, onboard the LearJet 25 at Glenn. NASA worked with Honeywell, Inc., for the broadcast VDL Mode 2 datalink capability and with actual Boeing 757 aircraft data. This demonstration used a cockpitmounted camera for video surveillance and a coupling to

The Advanced Communications Technology Satellite (ACTS) was conceived at the National Aeronautics and Space Administration (NASA) in the late 1970's as a follow-on program to ATS and CTS to continue NASA's long history of satellite communications projects. The ACTS project set the stage for the C-band satellites that started the industry, and later the ACTS project established the use of Ku-band for video distribution and direct-to-home broadcasting. ACTS, launched in September 1993 from the space shuttle, created a revolution in satellite system architecture by using digital communications techniques employing key technologies such as a fast hopping multibeam antenna, an on-board baseband processor, a wide-band microwave switch matrix, adaptive rain fade compensation, and the use of 900 MHz transponders operating at Ka-band frequencies. This paper describes the lessons learned in each of the key ACTS technology areas, as well as in the propagation investigations.

2013-06-01

This qualitative study formed part of a large-scale, multi-phase study into the delivery of therapy services to people with a disability, living in one rural area of New South Wales, Australia. The study's purpose was to identify the impact of Information and Communication Technology on the workforce practices of occupational therapists' working in a rural area of New South Wales. Individual semi-structured telephone interviews were conducted with 13 occupational therapists working in disability, health and private practice in a rural area of New South Wales. Participants were asked about access to, skills and limitations of using Information and Communication Technology. A modified grounded theory approach, based on thematic analysis and constant comparison, was used to analyse the interview transcripts. This study found widespread use of technology by rurally based occupational therapists working in the disability sector in New South Wales. However, Information and Communication Technology was primarily used for client contact, professional development and professional networking rather than therapy provision. The study identified individual, workplace and community barriers to greater uptake of Information and Communication Technology by this group. The individual barriers included: age cohort, knowledge and personal preferences. The workplace barriers included: support and training and availability of resources. The community barriers included: infrastructure and perceptions of clients' acceptance. The potential exists for Information and Communication Technology to supplement face-to-face therapy provision, enhance access to professional development and reduce professional isolation thereby addressing the rural challenges of large distances, travel times and geographic isolation. To overcome these challenges, individual, workplace and community Information and Communication Technology barriers should be addressed concurrently. © 2012 The Authors Australian

Roett, Michelle A; Coleman, Mary Thoesen

2013-11-01

Patient portals (ie, secure web-based services for patient health record access) and secure messaging to health care professionals are gaining popularity slowly. Advantages of web portals include timely communication and instruction, access to appointments and other services, and high patient satisfaction. Limitations include inappropriate use, security considerations, organizational costs, and exclusion of patients who are uncomfortable with or unable to use computers. Attention to the organization's strategic plan and office policies, patient and staff expectations, workflow and communication integration, training, marketing, and enrollment can facilitate optimal use of this technology. Other communication technologies that can enhance patient care include automated voice or text reminders and brief electronic communications. Social media provide another method of patient outreach, but privacy and access are concerns. Incorporating telehealthcare (health care provided via telephone or Internet), providing health coaching, and using interactive health communication applications can improve patient knowledge and clinical outcomes and provide social support.

Ostherr, Kirsten; Killoran, Peter; Shegog, Ross; Bruera, Eduardo

2016-04-01

End-of-life (EOL) communication plays a critical role in ensuring that patients receive care concordant with their wishes and experience high quality of life. As the baby boomer population ages, scalable models of end-of-life communication will be needed to ensure that patients receive appropriate care. Information and communication technologies (ICTs) may help address the needs of this generation; however, few resources exist to guide the use of ICTs in EOL care. The primary objective was to identify the ICTs being used in EOL communication. The secondary objective was to compare the effectiveness of different ICTs in EOL communication. The study was a systematic review, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We systematically searched seven databases for experimental and observational studies on EOL communication between doctors and patients using ICTs, published in 1997-2013. The review identified 38 relevant articles. Eleven types of technology were identified: video, website, telephone, videoconferencing, e-mail, telemonitoring, Internet search, compact disc, fax, PalmPilot, and short message service (SMS) text messaging. ICTs were most commonly used to provide information or education, serve as decision aids, promote advance care planning (ACP), and relieve physical symptom distress. The use of ICTs in EOL care is a small but growing field of research. Additional research is needed to adapt older, analog technologies for use in the digital age. Many of the interventions discussed in this review do not take full advantage of the affordances of mobile, connected health ICTs. The growing evidence base for e-health applications in related fields should guide future interventions in EOL care.

McElroy, Lisa M; Ladner, Daniela P; Holl, Jane L

2013-12-01

Incomplete, fragmented and poorly organised communications contribute to more than half the errors that lead to adverse and sentinel events. Meanwhile, communication software and devices with expanding capabilities are rapidly proliferating and being introduced into the healthcare setting. Clinicians face a large communication burden, which has been exacerbated by the additional challenge of selecting a mode of communication. In addition to specific communication devices, some hospitals have implemented advanced technological systems to assist with communication. However, few studies have provided empirical evidence of the specific advantages and disadvantages of the different devices used for communication. Given the increasing quantities of information transmitted to and by clinicians, evaluations of how communication methods and devices can improve the quality, safety and outcomes of healthcare are needed.

The development of civilisation is linked inextricably with growing demand for electricity. Thus, the still-rapid increase in the level of utilisation of natural resources, including fossil fuels, leaves it more and more urgent that conventional energy technologies and the potential of the renewable energy sources be made subject to re-evaluation. It is estimated that last 200 years have seen use made of more than 50% of the available natural resources. Equally, if economic forecasts prove accurate, for at least several more decades, oil, natural gas and coal will go on being the basic primary energy sources. The alternative solution represented by nuclear energy remains a cause of considerable public concern, while the potential for use to be made of renewable energy sources is seen to be very much dependent on local environmental conditions. For this reason, it is necessary to emphasise the impact of research that focuses on the further sharpening-up of energy efficiency, as well as actions aimed at increasing society's awareness of the relevant issues. The history of recent centuries has shown that rapid economic and social transformation followed on from the industrial and technological revolutions, which is to say revolutions made possible by the development of power-supply technologies. While the 19th century was "the age of steam" or of coal, and the 20th century the era of oil and gas, the question now concerns the name that will at some point come to be associated with the 21st century. In this paper, the subjects of discussion are primary energy consumption and energy resources, though three international projects on the global scale are also presented, i.e. ITER, Hydrates and DESERTEC. These projects demonstrate new scientific and technical possibilities, though it is unlikely that commercialisation would prove feasible before 2050. Research should thus be focused on raising energy efficiency. The development of high-efficiency technologies that

The term "terahertz" has been ubiquitous in the arena of technology over the past couple of years. New applications are emerging every day which are exploiting the promises of terahertz - its small wavelength; capability of penetrating dust, clouds, and fog; and possibility of having large instantaneous bandwidth for high-speed communication channels. Until very recently, space-based instruments for astrophysics, planetary science, and Earth science missions have been the primary motivator for the development of terahertz sensors, sources, and systems. However, in recent years the emerging areas such as imaging from space platforms, surveillance of person-borne hidden weapons or contraband from a safe stand-off distance and reconnaissance, medical imaging and DNA sequencing, and in the world high speed communications have been the driving force for this area of research.

2017-01-01

To review the literature on communication technologies in rehabilitation for people with a traumatic brain injury (TBI), and: (a) determine its application to cognitive-communicative rehabilitation, and b) develop a model to guide communication technology use with people after TBI. This integrative literature review of communication technology in TBI rehabilitation and cognitive-communication involved searching nine scientific databases and included 95 studies. Three major types of communication technologies (assistive technology, augmentative and alternative communication technology, and information communication technology) and multiple factors relating to use of technology by or with people after TBI were categorized according to: (i) individual needs, motivations and goals; (ii) individual impairments, activities, participation and environmental factors; and (iii) technologies. While there is substantial research relating to communication technologies and cognitive rehabilitation after TBI, little relates specifically to cognitive-communication rehabilitation. Further investigation is needed into the experiences and views of people with TBI who use communication technologies, to provide the 'user' perspective and influence user-centred design. Research is necessary to investigate the training interventions that address factors fundamental for success, and any impact on communication. The proposed model provides an evidence-based framework for incorporating technology into speech pathology clinical practice and research.

Full Text Available The present study analyzes of the use of media and interactive resources for the empowerment of individuals in vulnerable situations to expand their possibilities of communication and social participation, starting from the report of the experience of a university extension program, which proposed the development and use of a blog among other media resources, in workshops activities, Dynamics and Projects that integrate an intervention of social occupational therapy with the poor youth. This experience allowed the expansion of the repertoire of activities of the youth, promoting awareness of concepts, techniques and equipment, previously little available, accessible and used. The records of the contents of the blog were done in a participatory manner, generating reflection on roles and identities. Being and doing in virtual space allowed actions and real productions of adolescents and youths to be empowered when “virtualized”, providing a dimension that is not always possible to achieve in the “real” context. The blog posts resulted in a self-valorization of the population, creating places of belonging for particular social subjects, with the right to culture, communication and technology. Consequently, there was the empowerment of subjects, from the increasing social participation and achievement of the new media, which expanded their sociocultural boundaries. Moreover, it offered an expansion of the scope of resources for action on social occupational therapy, opening spaces, real and virtual, for collective experiences, for sociability and the understanding and transformation of meanings about life and about the reality in which we live.

History of Antenna Technology for Mobile Communications in Korea

Science.gov (United States)

Min, Kyeong-Sik; Park, Chul-Keun; Kang, Suk-Youb

In this paper, we discuss the development of wireless and mobile communications in Korea, current technological trends, and the future outlook on technological developments. Since the introduction of the telegraph and the telephone in September 1885, Korea's wired and wireless communications industry has consistently developed for over 100 years. Since 1984, upon the provision of the mobile telecommunications service, the industry has seen drastic qualitative and quantitative growth in terms of both technical and economic aspects, which played a crucial role in the rapid growth of the digital industry in Korea. After the era of the analog cellular service based on the Advanced Mobile Phone System (AMPS), a precursor to the modern mobile service, Korea became the world's first country to commercialize Code Division Multiple Access (CDMA) in 1996 and succeeded in commercializing CDMA 2000 lx (IMT 2000) in 2001. With further developments in the mobile communication technology, the technology for antennas also saw drastic advancements. As the mobile antennas moved from the second to the third generation, they grew from external models to very small internal models. At the same time, they evolved into highly functional and high performance multiple band and wide band antennas. Furthermore, Korea was the first country to commercialize and offer the Wireless Broadband Internet (WiBro) service in 2006. By leading the wireless communications standardization and exerting remarkable efforts in research and development, Korea is consolidating its status as an Information Technology (IT) leader in the global market. The antenna's inherent importance will be further emphasized in the near future as it satisfies the performance and structural needs of portable terminals necessary for realizing the projected establishment of the ubiquitous world. It is thought that antenna technologies will not be limited to simple concepts as previously experienced but will utilize various kinds

Next wave EM technology : Electromagnetic communication technology continues to progress

Ludwick, J.

1998-01-01

Alpine Oil Services Corp. and Ryan Energy Technologies Inc., have made technological advances in the use of real time electromagnetic (EM) data transmission, using low frequency radio waves to transmit well commands or geological information. The development of the telemetry activated tool was done in two steps. The first technology was real time EM data transmission from the subsurface which used the wellbore to transfer information. The second step was constructing a memory pack which involved an electronic instrument installed in the wellbore which was programmed to perform certain tasks at certain times by transmitting signals back and forth. The use of EM communication allows the geological steering information to come back faster. The EM signal is much faster compared to MWD systems for deeper directional wells. The EM technology also has immediate applications in underbalanced drilling. 1 fig

As D2D user equipment (UE can cause interference to cellular UE, scheduling and allocation of channel resources and power of D2D communication need elaborate coordination. In this paper, we propose a joint scheduling and resource allocation scheme to improve the performance of D2D communication. We take UE rate and UE fairness into account by performing interference management. First, we construct a Stackelberg game framework in which we group a macrocellular UE, a femtocellular UE, and a D2D UE to form a two-leader one-follower pair. The cellular UE are leaders, and D2D UE is the follower who buys channel resources from the leaders. We analyze the equilibrium of the game and obtain solutions to the equilibrium. Second, we propose an algorithm for joint scheduling of D2D pairs based on their utility. Finally, we perform computer simulations to study the performance of the proposed scheme.

Childes, Jana M; Palmer, Andrew D; Fried-Oken, Melanie; Graville, Donna J

2017-02-01

The purpose of this article is to describe the characteristics and experiences of individuals who use technology to support telephone or face-to-face communication after total laryngectomy. An online questionnaire was used to identify potential participants. Seventeen individuals met inclusion criteria and participated in an in-depth survey. They were compared with a reference group matched for age, gender, and time postsurgery who did not use these technologies. Open-ended responses were summarized. Compared with the matched reference group, individuals who used technology to support verbal communication had undergone more aggressive cancer treatment and used more communication methods. They were less likely to use an alaryngeal speech method, had greater difficulty over the telephone, and used more repair strategies in face-to-face communication. The 2 groups did not differ significantly in the frequency or success of their communication, however. Open-ended responses revealed great variety with regard to their reasons, purposes, and timing of technology use. There is a subset of individuals using technology to support verbal communication very successfully after laryngectomy. Usage was not limited to those who were unable to communicate verbally and often continued long after the initial postoperative period in many settings, for various purposes, and in combination with other methods of communication.

Day, Arla; Paquet, Stephanie; Scott, Natasha; Hambley, Laura

2012-10-01

Although many employees are using more information communication technology (ICT) as part of their jobs, few studies have examined the impact of ICT on their well-being, and there is a lack of validated measures designed to assess the ICT factors that may impact employee well-being. Therefore, we developed and validated a measure of ICT demands and supports. Using Exploratory Structural Equation Modeling, we found support for 8 ICT demands (i.e., availability, communication, ICT control, ICT hassles, employee monitoring, learning, response expectations, and workload) and two facets of ICT support (personal assistance and resources/upgrades support). Jointly, the ICT demands were associated with increased strain, stress, and burnout and were still associated with stress and strain after controlling for demographics, job variables, and job demands. The two types of ICT support were associated with lower stress, strain, and burnout. Resources/upgrades support moderated the relationship between learning expectations and most strain outcomes and between ICT hassles and strain. Personal assistance support moderated the relationship between ICT hassles and strain.

Resource Allocation for Outdoor Visible Light Communications with Energy Harvesting Capabilities

KAUST Repository

Abdelhady, Amr Mohamed Abdelaziz

2018-01-25

Visible light communication (VLC) is a promising technology that can support high data rate services for outdoor mass gathering night events while permitting energy harvesting. In this paper, a VLC system is considered where a transmitter sends data to multiple users with energy harvesting capabilities. This multi-user VLC scenario can be supported using time division multiple access (TDMA). The achievable rates using TDMA are expressed in terms of the allocated resources per user, represented by average optical intensity and time slots. This allocation is to be optimized in order to maximize the average spectral efficiency while meeting power and quality-of-service (QoS) constraints. Herein, QoS is defined as a worst-case guaranteed rate and a minimum harvested energy. To solve this optimization, the optimality conditions are first derived. Then, an efficient algorithm is developed based on the derived conditions, and its near-optimality is verified through several numerical evaluations. The obtained performance is also compared to lower-complexity algorithms, thus reflecting the performance-complexity trade-off of these algorithms.

2017-09-01

Fifth Generation (5G) is the new evolution of mobile communication technology and will be launched soon in many countries. The researchers and designers of mobile communication technology have been facing the increasing demand of the mobile consumers, high data rates and mobility requirements needed by new wireless applications. Most of the countries have started research on 5G mobile communication technology that is predictable to be launched on 2020 in conjunction with the Olympic Games in Tokyo. Filterbank Multicarrier (FBMC) is one of the modulation techniques for the future 5G mobile communication technology. It uses the multicarrier techniques that are immune to fading caused by transmission of more than one path at a time and also immune to intersymbol interference besides able to function effectively compared to Orthogonal Frequency Division Multiplexing (OFDM) which is used in Fourth Generation (4G) mobile communications technology. This paper discusses the performance of FBMC over OFDM based on the previous journals that were investigated by researchers.

2014-01-01

Purpose This study examined adolescents’ technology-based sexual communication with dating partners, and evaluated associations between technology-based communication and condom use. Methods Participants were 176 high school students who indicated their use of technology to communicate with partners about condoms, birth control, STIs, HIV/AIDS, pregnancy, and sexual limits. Sexually active youth also reported their frequency of condom use. Results Many adolescents (49%) used technology to discuss sexual health with partners, with rates varying by topic. Girls were more likely than boys to discuss HIV, pregnancy, and sexual limits. Ethnic minorities were more likely than Whites to discuss condoms, STIs, HIV, pregnancy, and birth control. Importantly, rates of consistent condom use were three-times higher among youth using technology to discuss condoms and birth control. Conclusions Results provide novel preliminary evidence about adolescents’ use of technology to discuss sexual health, and demonstrate links between technology-based communication and condom use among sexually active youth.

Connolly, Denis J.; Bhasin, Kul B.; Romanofsky, Robert R.

1987-01-01

Future communications satellites are likely to use gallium arsenide (GaAs) monolithic microwave integrated-circuit (MMIC) technology in most, if not all, communications payload subsystems. Multiple-scanning-beam antenna systems are expected to use GaAs MMIC's to increase functional capability, to reduce volume, weight, and cost, and to greatly improve system reliability. RF and IF matrix switch technology based on GaAs MMIC's is also being developed for these reasons. MMIC technology, including gigabit-rate GaAs digital integrated circuits, offers substantial advantages in power consumption and weight over silicon technologies for high-throughput, on-board baseband processor systems. For the more distant future pseudomorphic indium gallium arsenide (InGaAs) and other advanced III-V materials offer the possibility of MMIC subsystems well up into the millimeter wavelength region. All of these technology elements are in NASA's MMIC program. Their status is reviewed.

Studies showing stronger scientific evidence related to speech, language and hearing pathology (SLP) have an impact on the prevention and rehabilitation of human communication and gained ground in SLP research agenda. In this paper we discuss some aspects and directions that should be considered for in-depth knowledge about speech, language and hearing needs in different population groups (age group, gender and other variables according to specific related disorders) for improved comprehensive care, successful efforts and effective use of financial and human resources. It is also discussed the decision making process for requesting complementary evaluations and tests, from routine to highly complex ones, that should be based on each test and/or procedure and their contribution to the diagnosis and therapeutic planning. In fact, it is crucial to have reliable parameters for planning, preventing and treating human communication and its related disorders. Epidemiology, biostatistics and social sciences can contribute with more specific information in human communication sciences and guide more specific studies on the international science and technology agenda, improving communication sciences involvement in the international health-related scientific scenario.

Giambra, Barbara K; Stiffler, Deborah; Broome, Marion E

2014-12-01

With advances in health care, the population of children who are technology-dependent is increasing and, therefore, the need for nurses to understand how best to engage in communication with the parents of these children is critical. Shared communication between the parents of hospitalized technology-dependent children and their nurses is essential to provide optimal care for the child. The components and behaviors of the parent-nurse communication process that improve mutual understanding of optimal care for the child had not previously been examined. Among parents of hospitalized technology-dependent children and their nurses, what communication behaviors, components, concepts, or processes improve mutual understanding of optimal care for the child? An integrative review of both qualitative and quantitative studies was conducted. Key words including communication, hospitalized, nurse, parent, pediatric, and technology-dependent were used to search databases such as Cumulative Index to Nursing and Allied Health and Medline for years 2000-2014. The data regarding the process of parent-nurse communication were extracted as they related to the mutual understanding of optimal care for the child. The data were grouped into themes and compared across studies, designs, populations, and settings. Six articles were identified that provided information regarding the processes of shared communication among the parents of hospitalized technology-dependent children and their nurses. Providing clear information, involving parents in care decisions, trust and respect for each other's expertise, caring attitudes, advocacy, and role negotiation were all found to be important factors in shared parent-nurse communication. The results of this integrative review inform our understanding of the parent-nurse communication process. The findings provide nurses with an understanding of strategies to better engage in respectful, engaging, and intentional communication with parents of

2012-01-01

Information and communication technology (ICT) has been advocated as a powerful tool for improving health education in low-resource settings. However, few evaluations have been performed of ICT perceptions and user experiences in low-resource settings. During late 2009, an internet-based survey on ICT was administered to students, tutors, and faculty members associated with a Community-Based Education and Service (COBES) program in Uganda. 255 surveys were completed. Response rates varied (students, 188/684, 27.5%; tutors, 14/27, 51.9%; faculty, 53/335, 15.8%). Most respondents owned mobile phones (98%). Students were less likely (p mobile phone coverage was almost universally present. Laptop ownership and internet and mobile phone access was not associated with high valuation of students' COBES experiences. Free text responses found that respondents valued ICT access for research, learning, and communication purposes. In summary, ICT penetration in this population is primarily manifest by extensive mobile phone ownership. Internet access in rural educational sites is still lacking, but students and educators appear eager to utilize this resource if availability improves. ICT may offer a unique opportunity to improve the quality of teaching and learning for COBES participants.

Access Control Mechanism for IoT Environments Based on Modelling Communication Procedures as Resources

Directory of Open Access Journals (Sweden)

Luis Cruz-Piris

2018-03-01

Full Text Available Internet growth has generated new types of services where the use of sensors and actuators is especially remarkable. These services compose what is known as the Internet of Things (IoT. One of the biggest current challenges is obtaining a safe and easy access control scheme for the data managed in these services. We propose integrating IoT devices in an access control system designed for Web-based services by modelling certain IoT communication elements as resources. This would allow us to obtain a unified access control scheme between heterogeneous devices (IoT devices, Internet-based services, etc.. To achieve this, we have analysed the most relevant communication protocols for these kinds of environments and then we have proposed a methodology which allows the modelling of communication actions as resources. Then, we can protect these resources using access control mechanisms. The validation of our proposal has been carried out by selecting a communication protocol based on message exchange, specifically Message Queuing Telemetry Transport (MQTT. As an access control scheme, we have selected User-Managed Access (UMA, an existing Open Authorization (OAuth 2.0 profile originally developed for the protection of Internet services. We have performed tests focused on validating the proposed solution in terms of the correctness of the access control system. Finally, we have evaluated the energy consumption overhead when using our proposal.

Language learning and the technology of international communications

Science.gov (United States)

Batley, Edward

1991-03-01

The author posits a reciprocal relationship between the recent popularisation of computer-based technology and the democratisation of Central and Eastern Europe. Brief reference is made to their common denominator, language and language change. The advent of the communicative approach to language learning and the new wave of language authenticity arising from it, both enhanced by the technological revolution, have made the defining of acceptability in the classroom and of communication in the process of testing more problematic than ever, although several advantages have also accrued. Advances in technology have generally outstripped our ability to apply their full or characteristic potential. While technology can personalise learning and in this way make learning more efficient, it can also impede motivation. Old methods, drills and routines are tending to be sustained by it. Lack of technology can also widen the gulf between developed, developing and underdeveloped countries of the world. The author proposes international partnerships as a means of preventing an imbalance which could threaten stability. Single language dominance is another threat to international understanding, given the growing awareness of our multilingual and multicultural environment. Enlightened language policies reaching from the individual to beyond the national community are needed, which adopt these aspects of language learning, explain decisions about the state's choice of languages and, at the same time, promote individual choice wherever practicable.

According to the prediction, in the next 10 years the wireless data traffic will be increased by 500-1000 times. Not only the wireless data traffic will be increased exponentially, and the demand for diversified traffic will be increased. Higher requirements for future mobile wireless communication system had brought huge market space for satellite communication system. At the same time, the space information networks had been greatly developed with the depth of human exploration of space activities, the development of space application, the expansion of military and civilian application. The core of spatial information networks is the satellite communication. The dissertation presented the communication system architecture, the communication protocol, the routing strategy, switch scheduling algorithm and the handoff strategy based on the satellite communication system. We built the simulation platform of the LEO satellites networks and simulated the key technology using OPNET.

1st International Ocean Technology Congress on EEZ Resources : Technology Assessment

CERN Document Server

Champ, Michael

1990-01-01

Today western nations consume annually only a small percentage of their resources from the sea, despite the proclamation of Exclusive Economic Zones (EEZ) by many. In contrast, most Pacific Basin Countries obtain more than a quarter of their annual needs from the ocean. Determination of greater rewards from the development of marine resources is markedly inhibited by the limited technical abilities available to locate and assess them. Knowledge of Exclusive Economic Zone resources is schematic and generalised, and a detailed understanding of the geology and processes relating to the economic use of the seafloor is both fragmentary and very basic. Technology for mapping the mineral resources of continental shelves and ocean areas, except in active offshore hydrocarbon provinces, has been largely developed in pursuit of scientific objectives and competence to rapidly appraise economic potential is limited. Similarly, the capability to characterise and evaluate the other resources of the seas is rudimentary. The...
