The objective of this study was to explore perceptions of communication quality at pediatric rapid response events and to determine whether these perceptions differed between rapid response team (RRT) members (RRTm) and floor providers (FP). This survey study was conducted of clinical providers involved in RRT events at a tertiary care children's hospital. Perceptions of RRT communication were assessed by using a 5-point Likert scale, and qualitative comments were collected. Responses were compared between RRTm (responder nurses and intensive care fellows) and FP (floor nurses and resident physicians). Survey response was 64% (18 of 28) for RRTm and 70% (194 of 278) for FP. RRTm gave lower ratings than FP for communication of: (1) the purpose of the call; (2) airway and breathing; (3) circulation; (4) background information; and (5) possible diagnosis and treatment. RRTm were more likely than FP to indicate that description of background information delayed communication of critical management problems ("often": RRTm, 7 of 17 [41%]; FP, 23 of 175 [13%]; "always": RRTm, 2 of 18 [12%]; FP, 19 of 175 [11%]; P=.001 for overall comparison). A structured approach for communication was generally supported, although less strongly among floor nurses. Themes from qualitative responses included role confusion, fractured room entry, and a dismissive attitude by RRTm. A disconnect in perceived quality of communication was observed between RRTm and FP at pediatric rapid response events. A structured approach with well-defined roles may improve communication quality. Copyright © 2015 by the American Academy of Pediatrics.

The general structure of a free-space optical (FSO) communication system based on astronomical telescopes is proposed. The light path for astronomical observation and for communication can be easily switched. A separate camera is used as a star sensor to determine the pointing direction of the optical terminal's antenna. The new system exhibits rapid acquisition and is widely applicable in various astronomical telescope systems and wavelengths. We present a detailed analysis of the acquisition time, which can be decreased by one order of magnitude compared with traditional optical communication systems. Furthermore, we verify software algorithms and tracking accuracy.

The project of Nuclotron-based Ion Collider fAcility (NICA) that is under development at JINR (Dubna) is presented. The general goals of the project are experimental studies of both hot and dense baryonic matter and spin physics (in collisions of polarized protons and deuterons). The first program requires providing of heavy ion collisions in the energy range of √ {{s_{NN}}} = 4-11 Gev at average luminosity of L = 1 × 1027 cm-2 s-1 for 197Au79+ nuclei. The polarized beams mode is proposed to be used in energy range of √ {{s_{NN}}} = 12-27 Gev (protons at luminosity of L ≥ 1 × 1030 cm-2 s-1. The report contains description of the facility scheme and its characteristics in heavy ion operation mode. The Collider will be equipped with two detectors—MultiPurpose Detector (MPD), which is in an active stage of construction, and Spin Physics Detector (SPD) that is in the stage of conceptual design. Fixed target experiment "Baryonic matter at Nuclotron" (BM@N) will be performed in very beginning of the project. The wide program of applied researches at NICA facility is being developed as well.

We study the formation of fluid vorticity and the hyperon polarization in heavy-ion collisions at energies available at the JINR Nuclotron-based Ion Collider fAcility in the framework of the parton-hadron-string dynamic model, taking into account both hadronic and quark-gluonic (partonic) degrees of freedom. The vorticity properties in peripheral Au+Au collisions at √{sN N}=7.7 GeV are demonstrated and confronted with other models. The obtained result for the Λ polarization is in agreement with the experimental data by the STAR Collaboration, whereas the model is not able to explain the observed high values of the antihyperon Λ ¯ polarization.

This study examined the efficacy of video self modeling (VSM) using feedforward, to teach various goals of a picture exchange communication system (PECS). The participants were two boys with autism and one man with Down syndrome. All three participants were non-verbal with no current functional system of communication; the two children had long histories of PECS failure. A series of replications, with different length baselines, was used to examine whether video self modeling could replace the PECS method of teaching to achieve the same goals. All three participants showed rapid learning of their target behavior when introduced to their self modeling videos, and effects generalized without the need for further intervention. We conclude that VSM, using feedforward, can provide a fast, simple way of teaching the use of a picture-based communication system without the need for prompts or intensive operant conditioning. VSM may provide an accessible, easy-to-use alternative to common methods of teaching augmentative and alternative communication systems.

Using Multiple Schedules During Functional Communication Training to Promote Rapid Transfer of Treatment Effects

Multiple schedules with signaled periods of reinforcement and extinction have been used to thin reinforcement schedules during functional communication training (FCT) to make the intervention more practical for parents and teachers. We evaluated whether these signals would also facilitate rapid transfer of treatment effects from one setting to the next and from one therapist to the next. With two children, we conducted FCT in the context of mixed (baseline) and multiple (treatment) schedules introduced across settings or therapists using a multiple baseline design. Results indicated that when the multiple schedules were introduced, the functional communication response came under rapid discriminative control, and problem behavior remained at near-zero rates. We extended these findings with another individual by using a more traditional baseline in which problem behavior produced reinforcement. Results replicated those of the previous participants and showed rapid reductions in problem behavior when multiple schedules were implemented across settings. PMID:26384141

The NOvA experiment was built to study oscillation parameters, mass hierarchy, CP- violation phase in the lepton sector and θ23 octant, via vɛ appearance and vμ disappearance modes in both neutrino and antineutrino beams. These scientific goals require good knowledge about NOvA scintillator basic properties. The new test bench was constructed and upgraded at JINR. The main goal of this bench is to measure scintillator properties (for solid and liquid scintillators), namely α/β discrimination and Birk's coefficients for protons and other hadrons (quenching factors). This knowledge will be crucial for recovering the energy of the hadronic part of neutrino interactions with scintillator nuclei. α/β discrimination was performed on the first version of the bench for LAB-based and NOvA scintillators. It was performed again on the upgraded version of the bench with higher statistic and precision level. Preliminary result of quenching factors for protons was obtained. A technical description of both versions of the bench and current results of the measurements and analysis are presented in this work.

A highly versatile, highly portable emergency communication system which permits deployment in a very short time to cover both wide areas and distant isolated areas depending upon mission requirements. The system employs a plurality of lightweight, fully self-contained repeaters which are deployed within the mission area to provide communication between field teams, and between each field team and a mobile communication control center. Each repeater contains a microcomputer controller, the program for which may be changed from the control center by the transmission of digital data within the audible range (300-3,000 Hz). Repeaters are accessed by portable/mobile transceivers, other repeaters, and the control center through the transmission and recognition of digital data code words in the subaudible range.

The Nuclotron Ion Collider fAcility (NICA) accelerator complex is currently under construction at the Joint Institute for Nuclear Research (JINR) laboratory located in the city of Dubna in the Russian Federation. The main goal of NICA is to collide heavy ion nuclei to study the properties of the phase diagram of strongly interacting matter at high baryon density. In this accelerator complex, two big particle detectors are planned to be installed: Spin Physics Detector (SPD) and Multi-Purpose Detector (MPD). At the design luminosity, the event rate in the MPD interaction region is about 6 kHz; the total charged particle multiplicity would exceeds 1000 in the most central Au+Au collisions at \\sqrt{{sNN}} = 11 {{GeV}}. Since the middle of 2016 a group of researchers and students from Mexican institutions was formed (MEXnICA). The main goal of the MEXnICA group is to collaborate in the experimental efforts of MPD-NICA proposing a BEam-BEam counter detector which we called BEBE. In this written general aspects of MPD-NICA detector and BEBE are discussed. This material was shown in a contributed talk given at the XXXI Annual Meeting of the Mexican Division of Particles and Fields held in the Physics Department of CINVESTAV located in Mexico City during the last week of May 2017.

The aim of the present study was to identify stakeholder and program beneficiary needs and wants in relation to a netball communication strategy in Tonga. In addition, the study aimed to more clearly identify audience segments for targeting of communication campaigns and to identify any barriers or benefits to engaging in the physical activity program. A rapid assessment and response (RAR) methodology was used. The elicitation research encompassed qualitative fieldwork approaches, including semistructured interviews with key informants and focus group discussions with program beneficiaries. Desk research of secondary data sources supported in-field findings. A number of potential barriers to behavioural compliance existed, including cultural factors, gender discrimination, socioeconomic factors, stigmatising attitudes, the threat of domestic violence, infrastructure and training issues. Factors contributing to participation in physical activity included the fun and social aspects of the sport, incentives (including career opportunities, highlighting the health benefits of the activity and the provision of religious and cultural sanctions by local leaders towards the increased physical activity of women. The consultative approach of RAR provided a more in-depth understanding of the need for greater levels of physical activity and opportunities for engagement by all stakeholders. The approach facilitated opportunities for the proposed health behaviours to be realised through the communication strategy. Essential insights for the strategy design were identified from key informants, as well as ensuring future engagement of these stakeholders into the strategy. So what? The expanded use of RAR to inform the design of social marketing interventions is a practical approach to data collection for non-communicable diseases and other health issues in developing countries. The approach allows for the rapid mobilisation of scarce resources for the implementation of more

Matching and motor-imitation skills were assessed for 6 children with developmental disabilities, followed by training to request the same set of preferred items using exchange-based communication and manual signs. Three participants displayed both skills and rapidly acquired both communicative response forms. Three others displayed neither skill; 1 mastered exchange-based responses but not manual signs, and neither of the other 2 easily acquired either response form. PMID:19949531

The Climate Science Rapid Response Team - A Model for Science Communication

In recent years, there have been many independent initiatives which have commenced with the goal of improving communication between scientists and the larger public. These initiatives have often been motivated by the recognition that concerns amongst scientists related to the pending threats of climate change are not universally shared by the general public. Multiple studies have conclusively demonstrated that while the vast majority of climate scientists are in broad agreement that human-emitted greenhouse gases are causing increases in the Earth's temperature, the larger public is divided. Often, this divide mirrors divides on other political, societal, economic, or scientific issues. One unique approach to improve the conveyance of the state of climate-change science to the public is reflected by a self-organized effort of scientists themselves. This approach has lead to the formation of the Climate Science Rapid Response Team (CSRRT). The mission of this organization is to provide accurate and rapid information on any climate-science topic to general media and governmental inquirers. The CSRRT currently consists of approximately 135 world-class climate scientists whose members cover the sub-disciplines of climate change and include not only the natural sciences but also economics and policy. Since its formation, the CSRRT has fielded approximately four inquires each week from institutions that include The Associated Press, ABC, CBS, CNN, BBC, New York Times, Time of London, National Public Radio, The Guardian, The Washington Post, the Los Angeles Times, the Chicago Tribune, and the U.S. Congress, among others. Members of the CSRRT have been asked to provide quotations for news stories; they have also been asked to give radio, television, or print-media interviews. Some members of the CSRRT have undergone media training to help encourage the use of jargon-free language so that clear communication with the broader public can be more successful.

When desiging prototype sensors for environmental variables a critical step is a comparison campaign where the new sensor is compared to current state of the art sensors. In this step one of the headaches for researchers can be connecting their sensor to a logging or communication device. I present a simple solution: to use smartphone that scans for Bluetooth Low Energy transmissions and uploads any measurement to a data server. In this way the prototype sensor only has to transmit its measurement values over BLE, which can be done using off-the-shelf components. The sensors don't have to be physically connected to the phone, allowing for very rapid deployment of sensors in locations that have a communication hub (ie. phone) installed. The communication and logging hub consists of nothing more than a low cost Android smartphone running a dedicated app. The phone is encased in a waterproof box with a large powerbank and a solar panel. I will demonstrate this live at the Fall Meeting. By installing these phones along permanent WMO certified station locations, comparisons campaigns can use the "golden standard" from the WMO without much problems.

Rapid response teams (RRT) are an important safety strategy in the prevention of deaths in patients who are progressively failing outside of the intensive care unit. The goal is to intervene before a critical event occurs. Effective teamwork and communication skills are frequently cited as critical success factors in the implementation of these teams. However, there is very little literature that clearly provides an education strategy for the development of these skills. Training in simulation labs offers an opportunity to assess and build on current team skills; however, this approach does not address how to meet the gaps in team communication and relationship skill management. At Hamilton Health Sciences (HHS) a two-day program was developed in collaboration with the RRT Team Leads, Organizational Effectiveness and Patient Safety Leaders. Participants reflected on their conflict management styles and considered how their personality traits may contribute to team function. Communication and relationship theories were reviewed and applied in simulated sessions in the relative safety of off-site team sessions. The overwhelming positive response to this training has been demonstrated in the incredible success of these teams from the perspective of the satisfaction surveys of the care units that call the team, and in the multi-phased team evaluation of their application to practice. These sessions offer a useful approach to the development of the soft skills required for successful RRT implementation.

Evolution of rapid nerve conduction.

Rapid conduction of nerve impulses is a priority for organisms needing to react quickly to events in their environment. While myelin may be viewed as the crowning innovation bringing about rapid conduction, the evolution of rapid communication mechanisms, including those refined and enhanced in the evolution of myelin, has much deeper roots. In this review, a sequence is traced starting with diffusional communication, followed by transport-facilitated communication, the rise of electrical signaling modalities, the invention of voltage-gated channels and "all-or-none" impulses, the emergence of elongate nerve axons specialized for communication and their fine-tuning to enhance impulse conduction speeds. Finally within the evolution of myelin itself, several innovations have arisen and have been interactively refined for speed enhancement, including the addition and sealing of layers, their limitation by space availability, and the optimization of key parameters: channel density, lengths of exposed nodes and lengths of internodes. We finish by suggesting several design principles that appear to govern the evolution of rapid conduction. This article is part of a Special Issue entitled SI: Myelin Evolution. Copyright © 2016.

Background In September 2007, an outbreak of acute hemorrhagic conjunctivitis (AHC) occurred in Keelung City and spread to Taipei City. In response to the epidemic, a new crisis management program was implemented and tested in Taipei. Methodology and Principal Findings Having noticed that transmission surged on weekends during the Keelung epidemic, Taipei City launched a multi-channel mass risk communications program that included short message service (SMS) messages sent directly to approximately 2.2 million Taipei residents on Friday, October 12th, 2007. The public was told to keep symptomatic students from schools and was provided guidelines for preventing the spread of the disease at home. Epidemiological characteristics of Taipei's outbreak were analyzed from 461 sampled AHC cases. Median time from exposure to onset of the disease was 1 day. This was significantly shorter for cases occurring in family clusters than in class clusters (mean±SD: 2.6±3.2 vs. 4.39±4.82 days, p = 0.03), as well as for cases occurring in larger family clusters as opposed to smaller ones (1.2±1.7 days vs. 3.9±4.0 days, p<0.01). Taipei's program had a significant impact on patient compliance. Home confinement of symptomatic children increased from 10% to 60% (p<0.05) and helped curb the spread of AHC. Taipei experienced a rapid decrease in AHC cases between the Friday of the SMS announcement and the following Monday, October 15, (0.70% vs. 0.36%). By October 26, AHC cases reduced to 0.01%. The success of this risk communication program in Taipei (as compared to Keelung) is further reflected through rapid improvements in three epidemic indicators: (1) significantly lower crude attack rates (1.95% vs. 14.92%, p<0.001), (2) a short epidemic period of AHC (13 vs. 34 days), and (3) a quick drop in risk level (1∼2 weeks) in Taipei districts that border Keelung (the original domestic epicenter).

Objective Patients commonly show signs and symptoms of deterioration for hours or days before cardiorespiratory arrest. Rapid response teams (RRT) were created to improve recognition and response to patient deterioration in these situations. Activation criteria include vital signs or 'general concern' by a clinician or family member. The general concern criterion for RRT activation accounts for nearly one-third of all RRT activity, and although it is well established that communication deficits between staff can contribute to poorer outcomes for patients, there is little evidence pertaining to communication and its effects on the general concern RRT activation. Thus, the aim of the present study was to develop a substantive grounded theory related to the communication process between clinicians that preceded the activation of an RRT when general concern criterion was used. Methods Qualitative grounded theory involved collection of three types of data details namely personal notes from participants in focus groups with white board notes from discussions and audio recordings of the focus groups sessions. Focus groups were conducted with participants exploring issues associated with clinician communication and how it related to the activation of an RRT using the general concern criterion. Results The three main phases of coding (i.e. open, axial and selective coding) analysis identified 322 separate open codes. The strongest theme contributed to a theory of ineffective communication and decreased psychological safety, namely that 'In the absence of effective communication there is a subsequent increase in anxiety, fear or concern that can be directly attributed to the activation of an RRT using the 'general concern' criterion'. The RRT filled cultural and process deficiencies in the compliance with an escalation protocol. Issues such as 'not for resuscitation documentation' and 'inability to establish communication with and between medical or nursing personnel' rated

currently, it takes at least 6 months for researchers to communicate their results. This delay is caused (a) by partial lacks of machine support for both representation as well as communication and (b) by media breaks during the communication process. To make an integrated communication between researchers and practitioners possible, a general structure for medical content representation has been set up. The procedure for data entry and quality management has been generalized and implemented in a web-based authoring system. The MedRapid-system supports the medical experts in entering their knowledge into a database. Here, the level of detail is still below that of current medical guidelines representation. However, the symmetric structure for an area-wide medical knowledge representation is highly retrievable and thus can quickly be communicated into daily routine for the improvement of the treatment quality. In addition, other sources like journal articles and medical guidelines can be references within the MedRapid-system and thus be communicated into daily routine. The fundamental system for the representation of medical reference knowledge (from reference works/books) itself is not sufficient for the friction-less communication amongst medical staff. Rather, the process of (a) representing medical knowledge, (b) refereeing the represented knowledge, (c) communicating the represented knowledge, and (d) retrieving the represented knowledge has to be unified. MedRapid will soon support the whole process on one server system.

Exposure to smoke emitted from wildfire and planned burns (i.e., smoke events) has been associated with numerous negative health outcomes, including respiratory symptoms and conditions. This rapid review investigates recent evidence (post-2009) regarding the effectiveness of public health messaging during smoke events. The objectives were to determine the effectiveness of various communication channels used and public health messages disseminated during smoke events, for general and at-risk populations. A search of 12 databases and grey literature yielded 1775 unique articles, of which 10 were included in this review. Principal results were: 1) Smoke-related public health messages are communicated via a variety of channels, but limited evidence is available regarding their effectiveness for the general public or at-risk groups. 2) Messages that use simple language are more commonly recalled, understood, and complied with. Compliance differs according to socio-demographic characteristics. 3) At-risk groups may be advised to stay indoors before the general population, in order to protect the most vulnerable people in a community. The research included in this review was observational and predominantly descriptive, and is therefore unable to sufficiently answer questions regarding effectiveness. Experimental research, as well as evaluations, are required to examine the effectiveness of modern communication channels, channels to reach at-risk groups, and the 'stay indoors' message.

A neutron activation analysis (NAA) of three samples of human remains of the 16th and 17th centuries from the necropolises of the Moscow Kremlin has been carried out at FLNP JINR. The samples were irradiated at two facilities: the IREN source of resonance neutrons and the IBR-2 reactor. Spectra of the induced activity of the irradiated samples were measured by using the automatic measurement system developed at the Frank Laboratory of Neutron Physics (FLNP) of the Joint Institute for Nuclear Research (JINR). This system consists of a high-purity germanium detector with spectrometric electronics, a sample changer, and control software. Mass fraction of arsenic, mercury, and some other elements were calculated using two NAA methods—relative and absolute. The obtained values confirm the fact of acute mercury poisoning of Anastasia Romanovna, the first wife of Tsar Ivan Vasil'evich the Terrible, the first Russian Tsarina (died in 1560). High levels of mercury were detected in the bone remains of Tsarevich Ivan Ivanovich (died in 1581), the son of Tsar Ivan the Terrible, and Prince Mikhail Vasil'evich Skopin-Shuiskii (died in 1610). The results provide an opportunity to introduce into scientific circulation the exact values of mass fraction of mercury, arsenic, and other elements in the samples taken from the burials of the Russian historical figures of the second half of 16th-early 17th century.

The communications industry has been rapidly converting from analog to digital communications for audio, video, and data. The initial applications have been concentrating on point-to-multipoint transmission. Currently, a new revolution is occurring in which two-way point-to-point transmission is a rapidly growing market. The system designs for video compression developed for point-to-multipoint transmission are unsuitable for this new market as well as for satellite based video encoding. A new system developed by the Space Communications Technology Center has been designed to address both of these newer applications. An update on the system performance and design will be given.

Information and communication technologies can be a valuable tool for enhancing health communication. However, not everyone is utilising the wide suite of digital opportunities. This disparity has the potential to exacerbate existing social and health inequalities, particularly among vulnerable groups such as those who are in poor health and the elderly. This review aimed to systematically identify the common barriers to, and facilitators of, digital inclusion. A comprehensive database search yielded 969 citations. Following screening, seven systematic reviews and three non-systematic reviews were identified. Collectively, the reviews found that physical access continues to be a barrier to digital inclusion. However, provision of access alone is insufficient, as digital ability and attitude were also potential barriers. Social support, direct user experience and collaborative learning/design were identified as key strategies to improve inclusion. These review findings provide guidance for health communication practitioners in designing and implementing effective programmes in the digital environment.

in the epicentral area. UNAVCO has developed and deplyed standalone data communications systems at 25 of the stations: (1) the satellite-based Inmarsat Broad Global Area Service (BGAN), (2) ground based cellular internet services provided by a number of telecom companies in Chile and Argentina. Cellular service is economical but prone to disruptions following earthquakes and coverage is limited. BGAN is expensive but robust and globally available. This communication plan has allowed for daily downloads of 15 sec. data and of 1 sec. data recorded during aftershocks of M6.5 and greater. RINEX files from these stations are publicly available at the UNAVCO Facility Archive immediately after data are downloaded, a first for Event Response GPS data. This effort will serve as the type example in the geodetic community for rapid CGPS data communications following a destructive earthquake. The communications system hardware purchased during this response will become part of the UNAVCO pool after one year and will be available for future PI projects and event responses.

The picture exchange communication system.

Bondy, A S; Frost, L A

1998-01-01

The Picture Exchange Communication System (PECS) was developed as a means to teach children with autism and related developmental disabilities a rapidly acquired, self-initiating, functional communication system. Its theoretical roots combine principles from applied behavior analysis and guidelines established within the field of alternative and augmentative communication. This approach has several potential advantages relative to imitation-based strategies (both vocal and gestural) and symbol selection strategies. The system begins with the exchange of simple icons but rapidly builds "sentence" structure. The system also emphasizes developing the request function prior to developing responding to simple questions and commenting. The development of requesting with a sentence structure also permits the rapid development of attributes more traditionally taught within a receptive mode. The relationship between the introduction of PECS and various other behavioral issues (i.e., social approach and behavior management) as well as its relationship to the codevelopment of speech are reviewed.

Käthner, Ivo; Kübler, Andrea; Halder, Sebastian

2015-01-01

Visual ERP (P300) based brain-computer interfaces (BCIs) allow for fast and reliable spelling and are intended as a muscle-independent communication channel for people with severe paralysis. However, they require the presentation of visual stimuli in the field of view of the user. A head-mounted display could allow convenient presentation of visual stimuli in situations, where mounting a conventional monitor might be difficult or not feasible (e.g., at a patient's bedside). To explore if similar accuracies can be achieved with a virtual reality (VR) headset compared to a conventional flat screen monitor, we conducted an experiment with 18 healthy participants. We also evaluated it with a person in the locked-in state (LIS) to verify that usage of the headset is possible for a severely paralyzed person. Healthy participants performed online spelling with three different display methods. In one condition a 5 × 5 letter matrix was presented on a conventional 22 inch TFT monitor. Two configurations of the VR headset were tested. In the first (glasses A), the same 5 × 5 matrix filled the field of view of the user. In the second (glasses B), single letters of the matrix filled the field of view of the user. The participant in the LIS tested the VR headset on three different occasions (glasses A condition only). For healthy participants, average online spelling accuracies were 94% (15.5 bits/min) using three flash sequences for spelling with the monitor and glasses A and 96% (16.2 bits/min) with glasses B. In one session, the participant in the LIS reached an online spelling accuracy of 100% (10 bits/min) using the glasses A condition. We also demonstrated that spelling with one flash sequence is possible with the VR headset for healthy users (mean: 32.1 bits/min, maximum reached by one user: 71.89 bits/min at 100% accuracy). We conclude that the VR headset allows for rapid P300 BCI communication in healthy users and may be a suitable display option for severely

The disadvantage of combinatorial communication.

Combinatorial communication allows rapid and efficient transfer of detailed information, yet combinatorial communication is used by few, if any, non-human species. To complement recent studies illustrating the advantages of combinatorial communication, we highlight a critical disadvantage. We use the concept of information value to show that deception poses a greater and qualitatively different threat to combinatorial signalling than to non-combinatorial systems. This additional potential for deception may represent a strategic barrier that has prevented widespread evolution of combinatorial communication. Our approach has the additional benefit of drawing clear distinctions among several types of deception that can occur in communication systems.

The communication relationship between parents of children or young people with health conditions and health professionals is an important part of treatment, but it is unclear how far the use of digital clinical communication tools may affect this relationship. The objective of our study was to describe, assess the feasibility of, and explore the impact of digital clinical communication between families or caregivers and health professionals. We searched the literature using 5 electronic databases. We considered all types of study design published in the English language from January 2009 to August 2015. The population of interest included families and caregivers of children and young people aged less than 26 years with any type of health condition. The intervention was any technology permitting 2-way communication. We included 31 articles. The main designs were randomized controlled trials (RCTs; n=10), cross-sectional studies (n=9), pre- and postintervention uncontrolled (pre/post) studies (n=7), and qualitative interview studies (n=2); 6 had mixed-methods designs. In the majority of cases, we considered the quality rating to be fair. Many different types of health condition were represented. A breadth of digital communication tools were included: videoconferencing or videoconsultation (n=14), and Web messaging or emails (n=12). Health care professionals were mainly therapists or cognitive behavioral therapists (n=10), physicians (n=8), and nurses (n=6). Studies were very heterogeneous in terms of outcomes. Interventions were mainly evaluated using satisfaction or acceptance, or outcomes relating to feasibility. Clinical outcomes were rarely used. The RCTs showed that digital clinical communication had no impact in comparison with standard care. Uncontrolled pre/post studies showed good rates of satisfaction or acceptance. Some economic studies suggested that digital clinical communication may save costs. This rapid review showed an emerging body of literature on

Rapid Changes in Connexin-43 in Response to Genotoxic Stress Stabilize Cell–Cell Communication in Corneal Endothelium

Roh, Danny S.

2011-01-01

Purpose. To determine how corneal endothelial (CE) cells respond to acute genotoxic stress through changes in connexin-43 (Cx43) and gap junction intercellular communication (GJIC). Methods. Cultured bovine CE cells were exposed to mitomycin C or other DNA-damaging agents. Changes in the levels, stability, binding partners, and trafficking of Cx43 were assessed by Western blot analysis and immunostaining. Live-cell imaging of a Cx43–green fluorescent protein (GFP) fusion protein was used to evaluate internalization of cell surface Cx43. Dye transfer and fluorescent recovery after photobleaching (FRAP) assessed GJIC. Results. After genotoxic stress, Cx43 accumulated in large gap junction plaques, had reduced zonula occludens-1 binding, and displayed increased stability. Live-cell imaging of Cx43–GFP plaques in stressed CE cells revealed reduced gap junction internalization and degradation compared to control cells. Mitomycin C enhanced transport of Cx43 from the endoplasmic reticulum to the cell surface and formation of gap junction plaques. Mitomycin C treatment also protected GJIC from disruption after cytokine treatment. Discussion. These results show a novel CE cell response to genotoxic stress mediated by marked and rapid changes in Cx43 and GJIC. This stabilization of cell–cell communication may be an important early adaptation to acute stressors encountered by CE. PMID:21666237

2011-01-01

Background Tuberculosis remains a major public health problem in India with the country accounting for 1 in 5 of all TB cases reported globally. An advocacy, communication and social mobilisation project for Tuberculosis control was implemented and evaluated in Odisha state of India. The purpose of the study was to identify the impact of project interventions including the use of 'Interface NGOs' and involvement of community groups such as women's self-help groups, local government bodies, village health sanitation committees, and general health staff in promoting TB control efforts. Methods The study utilized a rapid assessment and response (RAR) methodology. The approach combined both qualitative field work approaches, including semi-structured interviews and focus group discussions with empirical data collection and desk research. Results Results revealed that a combination of factors including the involvement of Interface NGOs, coupled with increased training and engagement of front line health workers and community groups, and dissemination of community based resources, contributed to improved awareness and knowledge about TB in the targeted districts. Project activities also contributed towards improving health worker and community effectiveness to raise the TB agenda, and improved TB literacy and treatment adherence. Engagement of successfully treated patients also assisted in reducing community stigma and discrimination. Conclusion The expanded use of advocacy, communication and social mobilisation activities in TB control has resulted in a number of benefits. These include bridging pre-existing gaps between the health system and the community through support and coordination of general health services stakeholders, NGOs and the community. The strategic use of 'tailored messages' to address specific TB problems in low performing areas also led to more positive behavioural outcomes and improved efficiencies in service delivery.

Social communication in bats.

PubMed

Chaverri, Gloriana; Ancillotto, Leonardo; Russo, Danilo

2018-05-15

Bats represent one of the most diverse mammalian orders, not only in terms of species numbers, but also in their ecology and life histories. Many species are known to use ephemeral and/or unpredictable resources that require substantial investment to find and defend, and also engage in social interactions, thus requiring significant levels of social coordination. To accomplish these tasks, bats must be able to communicate; there is now substantial evidence that demonstrates the complexity of bat communication and the varied ways in which bats solve some of the problems associated with their unique life histories. However, while the study of communication in bats is rapidly growing, it still lags behind other taxa. Here we provide a comprehensive overview of communication in bats, from the reasons why they communicate to the diversity and application of different signal modalities. The most widespread form of communication is the transmission of a signaller's characteristics, such as species identity, sex, individual identity, group membership, social status and body condition, and because many species of bats can rely little on vision due to their nocturnal lifestyles, it is assumed that sound and olfaction are particularly important signalling modes. For example, research suggests that secretions from specialized glands, often in combination with urine and saliva, are responsible for species recognition in several species. These olfactory signals may also convey information about sex and colony membership. Olfaction may be used in combination with sound, particularly in species that emit constant frequency (CF) echolocation calls, to recognize conspecifics from heterospecifics, yet their simple structure and high frequency do not allow much information of individual identity to be conveyed over long distances. By contrast, social calls may encode a larger number of cues of individual identity, and their lower frequencies increase their range of detection. Social

1980-01-01

The increase in demand for satellite communications services brought about shortages in available transponder capacity, especially at C-band. Interest shifted to the Ku-band frequency and currently carriers are rapidly moving to secure orbital slots for future satellite development. Projections of communications service demands over the next decade indiate growth in voice, data, and video services such that saturation of both C-band and Ku-band will occur by 1990. Emphasis must and will shift to Ka-band (20/30 GHz) frequency for fixed-satellite service. Advanced technologies such as multibeam antennas coupled with on-board satellite switching to allow implementation in this band of very high capacity satellite systems will be applied to meet the demand. Satellite system concepts that are likely in the 1990's and are likely to bring a new dimension to satellite delivered communication service are presented. The NASA 30/20 GHz communications satellite system demonstration program is discussed with emphasis on the related technology development.

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.

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.

Lightwave communications is a necessity for the information age. Optical links provide enormous bandwidth, and the optical fiber is the only medium that can meet the modern society's needs for transporting massive amounts of data over long distances. Applications range from global high-capacity networks, which constitute the backbone of the internet, to the massively parallel interconnects that provide data connectivity inside datacenters and supercomputers. Optical communications is a diverse and rapidly changing field, where experts in photonics, communications, electronics, and signal processing work side by side to meet the ever-increasing demands for higher capacity, lower cost, and lower energy consumption, while adapting the system design to novel services and technologies. Due to the interdisciplinary nature of this rich research field, Journal of Optics has invited 16 researchers, each a world-leading expert in their respective subfields, to contribute a section to this invited review article, summarizing their views on state-of-the-art and future developments in optical communications.

The role of technology in clinician-to-clinician communication.

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.

Glacier Research Digital Science Communication Evolution 1996-2014

This talk will focus on the changes in communicating science in the last 20 years from the perspective of the same research project. Essentially the rapid innovation in online communication requires the scientist learning and utilizing a new platform of communication each year. To maintain relevant visibility and ongoing research activities requires finding synergy between the two. I will discuss how digital communication has inspired my research efforts. This talk will also examine overall visitation and media impact metrics over this period. From developing a highly visible glacier research web page in 1996, to writing more than 400 blog posts since 2008, and in 2014 utilizing a videographer and illustration artist in the field, this is the story of one scientist's digital communication-media evolution. The three main observations are that: 1) Overall visitation has not expanded as rapidly in the last decade. 2) Contact and cooperation with colleagues has expanded quite rapidly since 2008. 3) Media impact peaked in 2005, but is nearing that peak again. The key factors in visibility and media impact for a "small market" research institution/project has been providing timely and detailed content to collaborative sites, such as RealClimate, BAMS State of the Climate, Climate Denial Crock of the Week, and Skeptical Science that can then be repurposed by the media. A review of the visitor metrics to the digital glacier sites I have maintained from 1996-2014 indicate visibility of each platform has a similar growth curve, transitioning to a plateau, but overall visitation does not increase in kind with the increase in number of platforms. Media metrics is more event driven and does not follow the visitor metric pattern.

The purpose of this article is to further conceptualise the totality of on-ship CDPC activity as an integrated system and to suggest a few strategies for communications in such systems. The methods used to summarise standardisation and integration of ship-board CDPC procedures included a scientific literature review and a web search. The fields of the review were maritime, health, and technology sources. Special attention was paid to material dealing with communications methods and issues related to ship-board systems and methods to manage communicable diseases. Effective communications strategies are vital for the success of CDPC systems. I suggest some specific viewpoints and strategies to improve communications: (i) It is sometimes helpful to view the Constituent Relations Management (CRM) team as a system component. This view highlights the fact that an on-ship CDPC system will be well designed and maintained only if constituent relations are well designed and maintained. (ii) For rapid communications with appropriate groups of constituents, it is important to structure groups of constituents, with the ability to rapidly apply set-theoretic operations to those groups. (iii) Optimistic concurrency control is generally the appropriate general strategy for synchronisation of on-ship CDPC data locations and data storage types. This may be modified in special situations, in particular with a latest-update-wins policy for disease contraction data in an epidemic. (iv) To encourage traveller cooperation with CDPC efforts, cultural activities may be helpful.

Amateur radio communications in a disaster preparedness simulation When all else fails . . . amateur radio.

PubMed

McCamey, Randy; Yeager, Jennifer

During natural disasters, communications can be disrupted, which negatively impacts response time of first responders thus diminishing the level of care provided to disaster victims. In the fall of 2014, as part of a larger community-based participatory research study, the Tarleton Area Amateur Radio Club (TAARC) joined the Department of Nursing, Tarleton State University, and provided amateur radio communications during a disaster preparedness simulation. The simulation was conducted to determine the ability of the university to provide rapid response and render quality, acute healthcare to its neighbors during a natural disaster. The primary goals of the TAARC were to assess the ability to quickly establish radio communications, accurately relay messages, and establish rapport and affiliation between each facility commander and the amateur radio operators. It was determined that communication was key to provide quality care, and the inclusion of amateur radio operators in the simulation helped ensure rapid response times and rapid transport of critical victims.

Real-time communication has been playing an increasingly important role in our work, life and ocean monitor. With the rapid progress of computer and communication technique as well as the miniaturization of communication system, it is needed to develop the adaptable and reliable real-time communication software in the ocean monitor system. This paper involves the real-time communication software research based on the point-to-point satellite intercommunication system. The object-oriented design method is adopted, which can transmit and receive video data and audio data as well as engineering data by satellite channel. In the real-time communication software, some software modules are developed, which can realize the point-to-point satellite intercommunication in the ocean monitor system. There are three advantages for the real-time communication software. One is that the real-time communication software increases the reliability of the point-to-point satellite intercommunication system working. Second is that some optional parameters are intercalated, which greatly increases the flexibility of the system working. Third is that some hardware is substituted by the real-time communication software, which not only decrease the expense of the system and promotes the miniaturization of communication system, but also aggrandizes the agility of the system.

Synaptic communication between neurons and NG2+ cells.

PubMed

Paukert, Martin; Bergles, Dwight E

2006-10-01

Chemical synaptic transmission provides the basis for much of the rapid signaling that occurs within neuronal networks. However, recent studies have provided compelling evidence that synapses are not used exclusively for communication between neurons. Physiological and anatomical studies indicate that a distinct class of glia known as NG2(+) cells also forms direct synaptic junctions with both glutamatergic and GABAergic neurons. Glutamatergic signaling can influence intracellular Ca(2+) levels in NG2(+) cells by activating Ca(2+) permeable AMPA receptors, and these inputs can be potentiated through high frequency stimulation. Although the significance of this highly differentiated form of communication remains to be established, these neuro-glia synapses might enable neurons to influence rapidly the behavior of this ubiquitous class of glial progenitors.

Successful Climate Science Communication Strategies

Sinclair, P.

2016-12-01

In the past decade, efforts to communicate the facts of global change have not successfully moved political leaders and the general public to action. In response, a number of collaborative efforts between scientists and professional communicators, writers, journalists, bloggers, filmmakers, artists and others have arisen seeking to bridge that gap. As a result, a new cadre of science-literate communicators, and media-savvy scientists have made themselves visible across diverse mainstream, traditional, and social media outlets. Because of these collaborations, in recent years, misinformation, and disinformation have been successfully met with accurate and credible rebuttals within a single news cycle.Examples of these efforts is the Dark Snow Project, a science/communication collaboration focusing initially on accelerated arctic melt and sea level rise, and the Climate Science Rapid Response team, which matches professional journalists with appropriate science experts in order to respond within a single news cycle to misinformation or misunderstandings about climate science.The session will discuss successful examples and suggest creative approaches for the future.

The use of mobile technology is ubiquitous in modern society and is rapidly increasing in novel use. The use of mobile devices and software applications ("apps") as augmentative and alternative communication (AAC) is rapidly expanding in the community, and this is also reflected in the research literature. This article reports the social-communication outcome results of a meta-analysis of single-case experimental research on the use of high-tech AAC, including mobile devices, by individuals with intellectual and developmental disabilities, including autism spectrum disorder. Following inclusion determination, and excluding studies with poor design quality, raw data from 24 publications were extracted and included 89 A-B phase contrasts. Tau-U nonparametric, non-overlap effect size was used to aggregate the results across all studies for an omnibus and moderator analyses. Kendall's S was calculated for confidence intervals, p-values, and standard error. The omnibus analysis indicated overall low to moderate positive effects on social-communication outcomes for high-tech AAC use by individuals with intellectual and developmental disabilities.

Before twentieth centuries and during early twentieth centuries, communicable diseases were the major cause of morbidity and mortality in Korea. But reliable data are not available. After 1975, the overall morbidity and mortality from communicable diseases, rapidly declined. Recently many new pathogenic microbes were recognized: L. monocytogenes, Hantaan virus, Y. pseudotuberculosis, P. multocida, L. pneumophilia, Human immunodeficiency virus (HIV), G. seoi, H. capsulatum, C. burnetii, V. cholerae 0139, C. parvum, F. tularensis, E. coli 0157:H7, B. burgdorferi, S. Typhimurium DT104, Rotavirus, hepatitis C virus and so on. Since the first HIV infection recognized in 1985, the reported cases of infection and deaths from HIV/AIDS have been steady increased each year. Legionnaire's disease, E. coli 0157:H7 colitis, listeriosis and crytosporidiasis have been occurring just sporadically among immunocompromized cases. Many re-emerging communicable diseases were occurred in Korea: leptospirosis, malaria, endemic typhus, cholera, tsutsugamushi disease, salmonellosis, hepatitis A, shigellosis, mumps, measles, acute hemorrhagic conjunctivitis, brucellosis and so on. Leptospirosis and tsutsugamushi diseases have been noticed as major public health problems since 1980s. The malaria that had been virtually disappeared for a decade has reappeared from 1993 with striking increase of patients in recent 3-4 years. The distributions of salmonella and shigella serotypes have been changed a lot in recent few decades. Furthermore rapid emergence of antibiotic-resistant bacterial strains induces more difficult and complex problems in control of communicable diseases. We must recognize on the importance of environment and ecosystem conservation and careful prescription of anti-microbial agent in order to prevent communicable diseases.

Only eight years after the launc of Sputnik-1 by the Soviet Union, the first commercial satellite, 'Early Bird', entered service. In just twelve years commercial satellite service extended around the earth and became profitable. The reasons for the successful development of the communications satellite services in a comparatively short time are considered. These reasons are related to the presence of three ingredients, taking into account technology to create the system, communications requirements to form a market, and a management structure to implement the system. The formation of the concept of using earth orbiting satellites for telecommunications is discussed. It is pointed out that the years from 1958 to 1964 were the true 'experimental years' for satellite communications. The rapid development of technology during this crucial period is described, giving attention to passive satellites, active systems, and development satellites.

Improving operating room coordination: communication pattern assessment.

To capture communication patterns in operating room (OR) management to characterize the information needs of OR coordination. Technological applications can be used to change system processes to improve communication and information access, thereby decreasing errors and adverse events. The successful design of such applications relies on an understanding of communication patterns among healthcare professionals. Charge nurse communication was observed and documented at four OR suites at three tertiary hospitals. The data collection tool allowed rapid coding of communication patterns in terms of duration, mode, target person, and the purpose of each communication episode. Most (69.24%) of the 2074 communication episodes observed occurred face to face. Coordinating equipment was the most frequently occurring purpose of communication (38.7%) in all suites. The frequency of other purposes in decreasing order were coordinating patient preparedness (25.7%), staffing (18.8%), room assignment (10.7%), and scheduling and rescheduling surgery (6.2%). The results of this study suggest that automating aspects of preparing patients for surgery and surgical equipment management has the potential to reduce information exchange, decreasing interruptions to clinicians and diminishing the possibility of adverse events in the clinical setting.

Nutraceuticals, a combination of nutrition and pharmaceutical, have grown rapidly as a product globally. Nutraceuticals can be advertised directly to consumers as well as prescribed, and thus involve multiple stakeholders in the marketing communication process. The present study investigates the marketing communication aspects of nutraceuticals using 216 semistructured in-depth interviews including all stakeholders in the process such as company/brand, physicians, pharmacists, and consumers. The findings bring out the role of each participant in the communication process and a comprehensive picture of the same. The insights would facilitate the nutraceutical brands to understand and implement marketing effective communication strategies.

Rapid communication between neurons and astrocytes in primary cortical cultures.

PubMed

Murphy, T H; Blatter, L A; Wier, W G; Baraban, J M

1993-06-01

The identification of neurotransmitter receptors and voltage-sensitive ion channels on astrocytes (reviewed by Barres, 1991) has renewed interest in how these cells respond to neuronal activity. To investigate the physiology of neuron astrocyte signaling, we have employed primary cortical cultures that contain both neuronal and glial cells. As the neurons in these cultures exhibit synchronous spontaneous synaptic activity, we have used both calcium imaging and whole-cell recording techniques to identify physiological activity in astrocytes related to neuronal activity. Whole-cell voltage-clamp records from astrocytes revealed rapid inward currents that coincide with bursts of electrical activity in neighboring neurons. Calcium imaging studies demonstrate that these currents in astrocytes are not always associated with slowly propagating calcium waves. Inclusion of the dye Lucifer yellow within patch pipettes confirmed that astrocytes are extensively coupled to each other but not to adjacent neurons, indicating that the currents observed are not due to gap junction connections between these cell types. These currents do not reflect widespread diffusion of glutamate or potassium released during neuronal activity since a population of small, round, multipolar presumed glial cells that are not dye coupled to adjacent cells did not display electrical currents coincident with neuronal firing, even though they respond to locally applied glutamate and potassium. These findings indicate that, in addition to the relatively slow signaling conveyed by calcium waves, astrocytes also display rapid electrical responses to neuronal activity.

We are in an era of rapidly changing communication media, which is driving a major evolution in the modes of communicating science. In the past, a mainstay of scientific communication in popular media was through science “translators”; science journalists and presenters. These have now nearly disappeared and are being replaced by widespread dissemination through, e.g., the internet, blogs, YouTube and journalists who often have little scientific background and sharp deadlines. Thus, scientists are required to assume increasing responsibility for translating their scientific findings and calibrating their communications to non-technical audiences, a task for which they are often ill prepared, especially when it comes to controversial societal issues such as tobacco, evolution, and most recently climate change (Oreskes and Conway 2010). Such issues have been politicized and hi-jacked by ideological belief systems to such an extent that constructive dialogue is often impossible. Many scientists are excellent communicators, to their peers. But this requires careful attention to detail and logical explanation, open acknowledgement of uncertainties, and dispassionate delivery. These qualities become liabilities when communicating to a non-scientific audience where entertainment, attention grabbing, 15 second sound bites, and self assuredness reign (e.g. Olson 2009). Here we report on a program initiated by NCAR and UCAR to develop new approaches to science communication and to equip present and future scientists with the requisite skills. If we start from a sound scientific finding with general scientific consensus, such as the warming of the planet by greenhouse gases, then the primary emphasis moves from the “science” to the “art” of communication. The art cannot have free reign, however, as there remains a strong requirement for objectivity, honesty, consistency, and above all a resistance to advocating particular policy positions.

2012-08-01

Combat casualty care is distributed across professions and echelons of care. Communication within it is fragmented, inconsistent, and prone to failure. Daily checklists used during intensive care unit (ICU) rounds have been shown to improve compliance with evidence-based practices, enhance communication, promote consistency of care, and improve outcomes. Checklists are criticized because it is difficult to establish a causal link between them and their effect on outcomes. We investigated how checklists used during ICU rounds affect communication. We conducted this project in two military ICUs (burn and surgical/trauma). Checklists contained up to 21 questions grouped according to patient population. We recorded which checklist items were discussed during rounds before and after implementation of a "must address" checklist and compared the frequency of discussing items before checklist prompting. Patient discussions addressed more checklist items before prompting at the end of the 2-week evaluation compared with the 2-week preimplementation period (surgical trauma ICU, 36% vs. 77%, p < 0.0001; burn ICU, 47% vs. 72 %, p < 0.001). Most items were addressed more frequently in both ICUs after implementation. Key items such as central line removal, reduction of laboratory testing, medication reconciliation, medication interactions, bowel movements, sedation holidays, breathing trials, and lung protective ventilation showed significant improvements. Checklists modify communication patterns. Improved communication facilitated by checklists may be one mechanism behind their effectiveness. Checklists are powerful tools that can rapidly alter patient care delivery. Implementing checklists could facilitate the rapid dissemination of clinical practice changes, improve communication between echelons of care and between individuals involved in patient care, and reduce missed information.

2014-05-01

The Rapid Upper Limb Assessment (RULA) is an observation-based screening tool that has been used to assess postural risks of children in school settings. Studies using eye-tracking technology suggest that visual search strategies are influenced by experience in the task performed. This study investigated if experience in postural risk assessments contributed to differences in outcome scores on the RULA and the visual search strategies utilized. While wearing an eye-tracker, 16 student occupational therapists and 16 experienced occupational therapists used the RULA to assess 11 video scenarios of a child using different mobile information and communication technologies (ICT) in the home environment. No significant differences in RULA outcome scores, and no conclusive differences in visual search strategies between groups were found. RULA can be used as a screening tool for postural risks following a short training session regardless of the assessor's experience in postural risk assessments.

Single-case research; Independent verbal requests, imitated verbal requests, word approximations and independent picture requests were assessed in a toddler and a pre-schooler with autism before and during two interventions. Although both participants used some vocalizations over the course of the study, experimental control was not demonstrated and the participants did not acquire a functional communication system prior to the cessation of intervention. Future research should include additional, detailed reports that provide insight to why some children with autism do not respond to particular communication interventions and should investigate the pairing of particular child characteristics with targeted interventions.

Visual Communication in Web Design - Analyzing Visual Communication in Web Design

NASA Astrophysics Data System (ADS)

Thorlacius, Lisbeth

Web sites are rapidly becoming the preferred media choice for information search, company presentation, shopping, entertainment, education, and social contacts. And along with the various forms of communication that the Web offers the aesthetic aspects have begun to play an increasingly important role. However, studies in the design and the relevance of focusing on the aesthetic aspects in planning and using Web sites have only to a smaller degree been subject of theoretical reflection. For example, Miller (2000), Thorlacius (2001, 2002, 2005), Engholm (2002, 2003), and Beaird (2007) have been contributing to set a beginning agenda that address the aesthetic aspects. On the other hand, there is a considerable amount of literature addressing the theoretical and methodological aspects focusing on the technical and functional aspects. In this context it is the aim of this article to introduce a model for analysis of visual communication on websites.

Coupling Functions Enable Secure Communications

NASA Astrophysics Data System (ADS)

Stankovski, Tomislav; McClintock, Peter V. E.; Stefanovska, Aneta

2014-01-01

Secure encryption is an essential feature of modern communications, but rapid progress in illicit decryption brings a continuing need for new schemes that are harder and harder to break. Inspired by the time-varying nature of the cardiorespiratory interaction, here we introduce a new class of secure communications that is highly resistant to conventional attacks. Unlike all earlier encryption procedures, this cipher makes use of the coupling functions between interacting dynamical systems. It results in an unbounded number of encryption key possibilities, allows the transmission or reception of more than one signal simultaneously, and is robust against external noise. Thus, the information signals are encrypted as the time variations of linearly independent coupling functions. Using predetermined forms of coupling function, we apply Bayesian inference on the receiver side to detect and separate the information signals while simultaneously eliminating the effect of external noise. The scheme is highly modular and is readily extendable to support different communications applications within the same general framework.

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

Exploiting Listener Gaze to Improve Situated Communication in Dynamic Virtual Environments.

Garoufi, Konstantina; Staudte, Maria; Koller, Alexander; Crocker, Matthew W

2016-09-01

Beyond the observation that both speakers and listeners rapidly inspect the visual targets of referring expressions, it has been argued that such gaze may constitute part of the communicative signal. In this study, we investigate whether a speaker may, in principle, exploit listener gaze to improve communicative success. In the context of a virtual environment where listeners follow computer-generated instructions, we provide two kinds of support for this claim. First, we show that listener gaze provides a reliable real-time index of understanding even in dynamic and complex environments, and on a per-utterance basis. Second, we show that a language generation system that uses listener gaze to provide rapid feedback improves overall task performance in comparison with two systems that do not use gaze. Aside from demonstrating the utility of listener gaze in situated communication, our findings open the door to new methods for developing and evaluating multi-modal models of situated interaction.

2000-08-01

The advent of software-defined radios (products of DSP) with embedded processors capable of performing, communications functions (i.e., modulation) makes it possible for networks of radios to operate efficiently by changing its transmission characteristics (waveform) to fit the input data bandwidth requirements commensurate with received Eb/N0. It is also now feasible to have embedded within the network of radios a networking system capable of allocating bandwidth in accordance with current needs and priorities. The subject of battlefield networking can now also be addressed. A system with the multiple degrees of freedom (e.g., ability to manually and automatically change communications parameters to improve communications performance, spectrum management and the ability to incorporate different mission processing support) will provide the warfighter, those who support the warfighter and the rapidly expanding mission of our armed forces (i.e., peacekeeping, anti-terrorism) to meet an ever-changing mission and operational environment. This paper will address how such a robust communications system will enhance the mission of the specialist and make the products of his efforts a real-time tool for the shooter who must operate within the digitized battlespace.

Teamwork and communication: an effective approach to patient safety.

PubMed

Mujumdar, Sandhya; Santos, Diana

2014-01-01

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

Rapid change is occurring throughout the Arctic environmental system. The goal of the Arctic Report Card is to communicate the nature of the many changes to a diverse audience via the Worldwide Web. First published in 2006, the Arctic Report Card is a peer-reviewed publication containing clear, reliable and concise scientific information on the current state of the Arctic environment relative to observational records. Available only online, it is intended to be an authoritative source for scientists, teachers, students, decision-makers, policy-makers and the general public interested in the Arctic environment and science. The Arctic Report Card is organized into five sections: Atmosphere; Sea Ice & Ocean; Marine Ecosystem; Terrestrial Ecosystem; Terrestrial Cryosphere. Arctic Report Card 2012, the sixth annual update, comprised 20 essays on physical and biological topics prepared by an international team of 141 scientists from 15 different countries. For those who want a quick summary, the Arctic Report Card home page provides highlights of key events and findings, and a short video that is also available on YouTube. The release of the Report Card each autumn is preceded by a NOAA press release followed by a press conference, when the Web site is made public. The release of Arctic Report Card 2012 at an AGU Fall Meeting press conference on 5 December 2012 was subsequently reported by leading media organizations. The NOAA Arctic Web site, of which the Report Card is a part, is consistently at the top of Google search results for the keyword 'arctic', and the Arctic Report Card Web site tops search results for keyword "arctic report" - pragmatic indications of a Web site's importance and popularity. As another indication of the Web site's impact, in December 2012, the month when the 2012 update was released, the Arctic Report Card Web site was accessed by 19,851 unique sites in 105 countries, and 4765 Web site URLs referred to the Arctic Report Card.

Based on the cat-eye effect of optical system, free space optical communication based on cat-eye modulating retro-reflector can build communication link rapidly. Compared to classical free space optical communication system, system based on cat-eye modulating retro-reflector has great advantages such as building communication link more rapidly, a passive terminal is smaller, lighter and lower power consuming. The incident angle is an important factor of cat-eye effect, so it will affect the retro-reflecting communication link. In this paper, the principle and work flow of free space optical communication based on cat-eye modulating retro-reflector were introduced. Then, using the theory of geometric optics, the equivalent model of modulating retro-reflector with incidence angle was presented. The analytical solution of active area and retro-reflected light intensity of cat-eye modulating retro-reflector were given. Noise of PIN photodetector was analyzed, based on which, bit error rate of free space optical communication based on cat-eye modulating retro-reflector was presented. Finally, simulations were done to study the effect of incidence angle to the communication. The simulation results show that the incidence angle has little effect on active area and retro-reflected light intensity when the incidence beam is in the active field angle of cat-eye modulating retro-reflector. With certain system and condition, the communication link can rapidly be built when the incidence light beam is in the field angle, and the bit error rate increases greatly with link range. When link range is smaller than 35Km, the bit error rate is less than 10-16.

How to recognize the work of researchers in astronomy communication?

2015-08-01

One of the most important current trends in astronomy communication has been “change”. The field of astronomy communication has rapidly evolved in just the past few years, as new techniques and technologies have been adopted. Research astronomy has also visibly changed, as automation of survey systems and the launch of new telescopes has produced a tsunami of big data sets. Today, scientists and communicators must work together to navigate the raging waters of this data flood as they strive to keep our tech-savvy society informed.This invited talk will be given by Rick Fienberg.

Ganz, Jennifer B; Simpson, Richard L

2004-08-01

Few studies on augmentative and alternative communication (AAC) systems have addressed the potential for such systems to impact word utterances in children with autism spectrum disorders (ASD). The Picture Exchange Communication System (PECS) is an AAC system designed specifically to minimize difficulties with communication skills experienced by individuals with ASD. The current study examined the role of PECS in improving the number of words spoken, increasing the complexity and length of phrases, and decreasing the non-word vocalizations of three young children with ASD and developmental delays (DD) with related characteristics. Participants were taught Phases 1-4 of PECS (i.e., picture exchange, increased distance, picture discrimination, and sentence construction). The results indicated that PECS was mastered rapidly by the participants and word utterances increased in number of words and complexity of grammar.

Rapid developments in wireless communications are opening up opportunities for new ways to perform many types of analytical measurements that up to now have been restricted in scope due to the need to have access to centralised facilities. This paper will address both the potential for new applications and the challenges that currently inhibit more widespread integration of wireless communications with autonomous sensors and analytical devices. Key issues are identified and strategies for closer integration of analytical information and wireless communications systems discussed.

The future of scientific communication in the earth sciences: The impact of the internet

Publication on paper of research results following peer-review and editing has been the accepted means of scientific communication for several centuries. Today, the continued growth in the volume of scientific literature, the increased unit costs of archiving paper publications, and the rapidly increasing power and availability of electronic technology are creating tremendous pressures on traditional scientific communication. The earth sciences are not immune from these pressures, and the role of the traditional publication as the primary means of communication is rapidly changing. Electronic publications and network technology are radically altering the relationship between interpretative result and the underlying data. Earth science research institutions, including the Kansas Geological Survey, are experimenting with new forms of on-line publication that assure broad access to research and data and improve application of research results to societal problems.

Knowledge Preservation Techniques That Can Facilitate Intergroup Communications

Moreman, Douglas; Dyer, John; Coffee, John; Noga, Donald F. (Technical Monitor)

2000-01-01

We have developed tools, social methods and software, for (1) acquiring technical knowledge from engineers and scientists, (2) preserving that knowledge, (3) making the totality of our stored knowledge rapidly searchable. Our motivation has been, mainly, to preserve rare knowledge of senior engineers who are near retirement. Historical value of such knowledge, and also of our tools, has been pointed out to us by historians. We now propose the application these tools to enhancing communication among groups that are working jointly on a project. Of most value will be projects having groups among whom communication is rare and incomplete. We propose that discussions among members of a group be recorded in audio and that both the actual audio and transcriptions of that audio, and optional other pieces be combined into electronic, webpage-like "books". These books can then be searched rapidly by interested people in other groups. At points of particular interest, a searcher can zoom in on the text and even on the original recordings to pick up nuances (e.g. to distinguish a utterance said in seriousness from one in sarcasm). In this matter, not only can potentially valuable technical details be preserved for the future, but communication be enhanced during the life of a joint undertaking.

Farnham, John W

2006-01-01

When communications are needed the most desperately and most urgently, the difficulty of effecting the desired communications increases exponentially. Recent natural disasters in different parts of the world have provided eloquent testament to this. The history of disaster or emergency communications can provide us with a foundation for understanding the problems encountered today, and can offer us insight into how we might improve the systems and processes for communications. The first applications of communication technology that allowed messages to be sent more rapidly than the fastest form of transportation were mainly military in origin. This review takes us from the days of optical or visual telegraphy, through the early development of mobile and radio communications, and up to the current sophisticated technologies. We pay particular attention to the use of amateur radio operators in times of emergency, and relate their activities to those of the most effective military communications. The germane assumption made in this discussion is that any emergency or disaster communications would necessarily be involved in response and resolution of medical aspects of those emergencies.

Undergraduate Biotechnology Students' Views of Science Communication

Edmondston, Joanne Elisabeth; Dawson, Vaille; Schibeci, Renato

2010-12-01

Despite rapid growth of the biotechnology industry worldwide, a number of public concerns about the application of biotechnology and its regulation remain. In response to these concerns, greater emphasis has been placed on promoting biotechnologists' public engagement. As tertiary science degree programmes form the foundation of the biotechnology sector by providing a pipeline of university graduates entering into the profession, it has been proposed that formal science communication training be introduced at this early stage of career development. The aim of the present study was to examine the views of biotechnology students towards science communication and science communication training. Using an Australian biotechnology degree programme as a case study, 69 undergraduates from all three years of the programme were administered a questionnaire that asked them to rank the importance of 12 components of a biotechnology curriculum, including two science communication items. The results were compared to the responses of 274 students enrolled in other science programmes. Additional questions were provided to the second year biotechnology undergraduates and semi-structured interviews were undertaken with 13 of these students to further examine their views of this area. The results of this study suggest that the biotechnology students surveyed do not value communication with non-scientists nor science communication training. The implications of these findings for the reform of undergraduate biotechnology courses yet to integrate science communication training into their science curriculum are discussed.

Communication theory and the search for effective feedback.

Simonds, S K

1995-01-01

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

Multiplexed Sequence Encoding: A Framework for DNA Communication.

PubMed

Zakeri, Bijan; Carr, Peter A; Lu, Timothy K

2016-01-01

Synthetic DNA has great propensity for efficiently and stably storing non-biological information. With DNA writing and reading technologies rapidly advancing, new applications for synthetic DNA are emerging in data storage and communication. Traditionally, DNA communication has focused on the encoding and transfer of complete sets of information. Here, we explore the use of DNA for the communication of short messages that are fragmented across multiple distinct DNA molecules. We identified three pivotal points in a communication-data encoding, data transfer & data extraction-and developed novel tools to enable communication via molecules of DNA. To address data encoding, we designed DNA-based individualized keyboards (iKeys) to convert plaintext into DNA, while reducing the occurrence of DNA homopolymers to improve synthesis and sequencing processes. To address data transfer, we implemented a secret-sharing system-Multiplexed Sequence Encoding (MuSE)-that conceals messages between multiple distinct DNA molecules, requiring a combination key to reveal messages. To address data extraction, we achieved the first instance of chromatogram patterning through multiplexed sequencing, thereby enabling a new method for data extraction. We envision these approaches will enable more widespread communication of information via DNA.

Despite the ambiguity inherent in human communication, people are remarkably efficient in establishing mutual understanding. Studying how people communicate in novel settings provides a window into the mechanisms supporting the human competence to rapidly generate and understand novel shared symbols, a fundamental property of human communication. Previous work indicates that the right posterior superior temporal sulcus (pSTS) is involved when people understand the intended meaning of novel communicative actions. Here, we set out to test whether normal functioning of this cerebral structure is required for understanding novel communicative actions using inhibitory low-frequency repetitive transcranial magnetic stimulation (rTMS). A factorial experimental design contrasted two tightly matched stimulation sites (right pSTS vs left MT+, i.e., a contiguous homotopic task-relevant region) and tasks (a communicative task vs a visual tracking task that used the same sequences of stimuli). Overall task performance was not affected by rTMS, whereas changes in task performance over time were disrupted according to TMS site and task combinations. Namely, rTMS over pSTS led to a diminished ability to improve action understanding on the basis of recent communicative history, while rTMS over MT+ perturbed improvement in visual tracking over trials. These findings qualify the contributions of the right pSTS to human communicative abilities, showing that this region might be necessary for incorporating previous knowledge, accumulated during interactions with a communicative partner, to constrain the inferential process that leads to action understanding.

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

Ligon, Russell A; McGraw, Kevin J

2013-01-01

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

Effective communication between healthcare staff and patients is central to development of the patient-professional relationship. Many barriers influence this communication, often resulting in patients' lack of understanding and retention of information, particularly affecting advice regarding lifestyle habits, such as alcohol consumption and smoking. Alcohol and smoking misuse are potentially modifiable risk factors known to adversely affect a variety of gastroenterological conditions and improvements in communication with patients regarding this is an important management component. This review discusses the clinical impact of these factors and how healthcare professionals can improve communication. We discuss how enhancing verbal communication skills through medical training leads to greater outcomes in patient satisfaction and adherence to treatment and advice. In addition, with the rapid digitalisation of society, platforms such as social media and smartphone applications may be considered as adjuncts to traditional forms of communication.

Rapid and automatic speech-specific learning mechanism in human neocortex.

A unique feature of human communication system is our ability to rapidly acquire new words and build large vocabularies. However, its neurobiological foundations remain largely unknown. In an electrophysiological study optimally designed to probe this rapid formation of new word memory circuits, we employed acoustically controlled novel word-forms incorporating native and non-native speech sounds, while manipulating the subjects' attention on the input. We found a robust index of neurolexical memory-trace formation: a rapid enhancement of the brain's activation elicited by novel words during a short (~30min) perceptual exposure, underpinned by fronto-temporal cortical networks, and, importantly, correlated with behavioural learning outcomes. Crucially, this neural memory trace build-up took place regardless of focused attention on the input or any pre-existing or learnt semantics. Furthermore, it was found only for stimuli with native-language phonology, but not for acoustically closely matching non-native words. These findings demonstrate a specialised cortical mechanism for rapid, automatic and phonology-dependent formation of neural word memory circuits. Copyright © 2015. Published by Elsevier Inc.

Rapid response teams (RRTs) can effectively foster discussions about appropriate goals of care and address other emergent palliative care needs of patients and families facing life-threatening illness on hospital wards. In this article, The Improving Palliative Care in the ICU (IPAL-ICU) Project brings together interdisciplinary expertise and existing data to address the following: special challenges for providing palliative care in the rapid response setting, knowledge and skills needed by RRTs for delivery of high-quality palliative care, and strategies for improving the integration of palliative care with rapid response critical care. We discuss key components of communication with patients, families, and primary clinicians to develop a goal-directed treatment approach during a rapid response event. We also highlight the need for RRT expertise to initiate symptom relief. Strategies including specific clinician training and system initiatives are then recommended for RRT care improvement. We conclude by suggesting that as evaluation of their impact on other outcomes continues, performance by RRTs in meeting palliative care needs of patients and families should also be measured and improved.

Low data rate digital space communications

The low available transmitter power and the large frequency uncertainty constrain the data rate to be low. An all-digital communication receiver is proposed, and its feasibility is established. Although coherent systems should be used whenever practical, the noncoherent MFSK system is more suitable for very low data rates. The effect of Rician fading on the performance of MFSK receiver is studied. Fading characteristics of the Venus channel are examined based on the exponential model and available experimental data on the Venus atmosphere. Because of the requirement of high communication efficiency, three codes are evaluated and compared. The rapidly varying phase error at low data rate has great effects on the tracking loop behaviors which are examined by extensive computer study of the phase plane trajectories.

2005-01-01

Clinicians are rapidly gaining experience with online clinician-patient consultation, and more tools are becoming available to support these efforts. In addition, we now have evidence that using electronic communication is cost-effective to payers and appealing to patients and providers. At present, there appear to be few barriers to the adoption of these solutions for practices that use other online services. Security concerns can easily be overcome by using programs described in this commentary. Larger and longer studies that evaluate the benefits and cost savings in more detail may help convince other payers and providers of the utility of the Web-based programs. More studies are needed to understand the effect of dinician-patient electronic communication on the costs of caring for chronic illness. When these solutions also include support tools, such as electronic prescribing, which could improve patient safety and quality of care, they should be encouraged. In their article entitled, "Electrons in Flight-Email between Doctors and Patients," Delbanco and Sands postulate that the future of e-communication in medicine will be integrated with a patient-controlled health record and will include secure synchronous and asynchronous communication, video conferencing and messaging, instant transcription into the written record, full-patient access to the record, translation into different languages, connectivity to multiple data sources, incorporation of multi-media educational materials. It-will also allow data from home-based diagnostic technology to be sent to clinicians. "Electronic communication will move medicine inexorably toward such transparency, enabling doctors and patients to share knowledge, responsibility, and decision-making more equally. We need to explore rapidly how this change will affect the quality of care for patients and the quality of life for doctors."

Acoustic MIMO communications in a very shallow water channel

Zhou, Yuehai; Cao, Xiuling; Tong, Feng

2015-12-01

Underwater acoustic channels pose significant difficulty for the development of high speed communication due to highly limited band-width as well as hostile multipath interference. Enlightened by rapid progress of multiple input multiple output (MIMO) technologies in wireless communication scenarios, MIMO systems offer a potential solution by enabling multiple spatially parallel communication channels to improve communication performance as well as capacity. For MIMO acoustic communications, deep sea channels offer substantial spatial diversity among multiple channels that can be exploited to address simultaneous multipath and co-channel interference. At the same time, there are increasing requirements for high speed underwater communication in very shallow water area (for example, a depth less than 10 m). In this paper, a space-time multichannel adaptive receiver consisting of multiple decision feedback equalizers (DFE) is adopted as the receiver for a very shallow water MIMO acoustic communication system. The performance of multichannel DFE receivers with relatively small number of receiving elements are analyzed and compared with that of the multichannel time reversal receiver to evaluate the impact of limited spatial diversity on multi-channel equalization and time reversal processing. The results of sea trials in a very shallow water channel are presented to demonstrate the feasibility of very shallow water MIMO acoustic communication.

Cost Consideration for Future Communications Satellite

NASA Astrophysics Data System (ADS)

Iida, Takashi

2002-01-01

This paper discusses the cost driving factors of the future communications satellite rather than discussing its cost itself directly, in terms of development period of time, services, and R&D by government. In the first, a period of time for development of a communications system is discussed in comparison of satellite communications system with a terrestrial communications system. Generally speaking, the terrestrial communications system is developed in a short period. Especially, the recent network related IT technology changes very rapidly, like so-called as "Dog Year". On the other hand, it takes a long time, more than several years, to develop a satellite communications system. This paper will discuss this time period of development is how to influence the system realization in various cases. In the second, the service related cost is discussed. First, a mobile communications satellite system is considered as an example. The tremendous penetration speed of the terrestrial cellular phones prevents from the success of the mobile satellite communications system. The success of the mobile satellite communications system depends on how early and user friendly to develop its user terminals. Second, the broadcasting service is described as a successful example. It is described that the satellite broadcasting has a very competitive advantage to the terrestrial broadcasting service from the cost point of view. Finally, the cost of the technology R&D for the future communication satellite by the government is discussed. A model of the future communications satellite for next 30 years has been proposed(1)(2). As an example, this paper estimates the satellite cost of the 60 Gbps range of capacity which is called as 1.5G satellite, where the capacity of the second generation Internet satellite (2G) is 50-500 Gbps per satellite. In the paper, the R&D plan of the future communications satellite will be discussed as a next R&D project to the first generation Internet

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

JPL is under contract, through NASA, with the US Army to develop a state-of-the-art Command Center System for the US European Command (USEUCOM). The Command Center System will receive, process, and integrate force status information from various sources and provide this integrated information to staff officers and decision makers in a format designed to enhance user comprehension and utility. The system is based on distributed workstation class microcomputers, VAX- and SUN-based data servers, and interfaces to existing military mainframe systems and communication networks. JPL is developing the Command Center System utilizing an incremental delivery methodology called the Rapid Development Methodology with adherence to government and industry standards including the UNIX operating system, X Windows, OSF/Motif, and the Ada programming language. Through a combination of software engineering techniques specific to the Ada programming language and the Rapid Development Approach, JPL was able to deliver capability to the military user incrementally, with comparable quality and improved economies of projects developed under more traditional software intensive system implementation methodologies.

A pilot investigation in constructing crisis communications: what leads to best practice?

Crisis communications can play an important role in mitigating, or exacerbating, the psychological and behavioral reactions to critical incidents and disasters. Effective crisis communications can serve to mitigate anxiogenesis and direct rapid and focused rescue, recovery, and rehabilitative operations. Ambiguous and/or deceptive communications can serve to worsen mental health reactions and delay operational response and recovery (Everly, Strouse, & Everly, 2010). It seems, therefore, that inquiry into the content of acute crisis communications would be warranted Said more simply, given limited time, cryptic messaging in social media, and the "sound bite" mentality that seems to govern news dissemination, it is important to identify the most important content to convey in the wake of critical incidents and disasters. This paper reports on a pilot investigation into "best practices" for the construction of acute crisis communications.

RICHTER: A Smartphone Application for Rapid Collection of Geo-Tagged Pictures of Earthquake Damage

NASA Astrophysics Data System (ADS)

Skinnemoen, H.; Bossu, R.; Furuheim, K.; Bjorgo, E.

2010-12-01

RICHTER (Rapid geo-Images for Collaborative Help Targeting Earthquake Response) is a smartphone version of a professional application developed to provide high quality geo-tagged image communication over challenging network links, such as satellites and poor mobile links. Developed for Android mobile phones, it allows eyewitnesses to share their pictures of earthquake damage easily and without cost with the Euro-Mediterranean Seismological Centre (EMSC). The goal is to engage citizens in the collection of the most up-to-date visual information on local damage for improved rapid impact assessment. RICHTER integrates the innovative and award winning ASIGN protocol initially developed for satellite communication between cameras / computers / satcom terminals and servers at HQ. ASIGN is a robust and optimal image and video communication management solution for bandwidth-limited communication networks which was developed for use particularly in emergency and disaster situations. Contrary to a simple Multimedia Messaging System (MMS), RICHTER allows access to high definition images with embedded location information. Location is automatically assigned from either the internal GPS, derived from the mobile network (triangulation) or the current Wi-Fi domain, in that order, as this corresponds to the expected positioning accuracy. Pictures are compressed to 20-30KB of data typically for fast transfer and to avoid network overload. Full size images can be requested by the EMSC either fully automatically, or on a case-by-case basis, depending on the user preferences. ASIGN was initially developed in coordination with INMARSAT and the European Space Agency. It was used by the Rapid Mapping Unit of the United Nations notably for the damage assessment of the January 12, 2010 Haiti earthquake where more than 700 photos were collected.

The attenuation characteristics of ultraviolet (UV) and infrared transmitting in the atmosphere is analyzed, when long-haul Non-Line-of-Sight (NLOS) optical scattering communication is considered. The effects of Rayleigh and Mie scattering to link performance are presented. Under given geometric configurations, a critical range RC is found. When communication range is shorter than RC, the attenuation of UV is lower than that of infrared. But the path loss of UV increases rapidly, while the path loss of infrared increases much slower. When communication range is longer than RC, the attenuation of UV is higher than that of infrared. Numerical values of RC under different geometries are analyzed. It is also indicated that, under arbitrary geometric configurations, the impact of the Rayleigh scattering to infrared scattering communication is weak, but to UV scattering, the Rayleigh scattering effect cannot be ignored.

Synthetic DNA has great propensity for efficiently and stably storing non-biological information. With DNA writing and reading technologies rapidly advancing, new applications for synthetic DNA are emerging in data storage and communication. Traditionally, DNA communication has focused on the encoding and transfer of complete sets of information. Here, we explore the use of DNA for the communication of short messages that are fragmented across multiple distinct DNA molecules. We identified three pivotal points in a communication—data encoding, data transfer & data extraction—and developed novel tools to enable communication via molecules of DNA. To address data encoding, we designed DNA-based individualized keyboards (iKeys) to convert plaintext into DNA, while reducing the occurrence of DNA homopolymers to improve synthesis and sequencing processes. To address data transfer, we implemented a secret-sharing system—Multiplexed Sequence Encoding (MuSE)—that conceals messages between multiple distinct DNA molecules, requiring a combination key to reveal messages. To address data extraction, we achieved the first instance of chromatogram patterning through multiplexed sequencing, thereby enabling a new method for data extraction. We envision these approaches will enable more widespread communication of information via DNA. PMID:27050646

Lubecke, Victor M.; Barber, Bradley P.; Arney, Susanne

2001-11-01

Modern communications demands have been steadily growing not only in size, but sophistication. Phone calls over copper wires have evolved into high definition video conferencing over optical fibers, and wireless internet browsing. The technology used to meet these demands is under constant pressure to provide increased capacity, speed, and efficiency, all with reduced size and cost. Various MEMS technologies have shown great promise for meeting these challenges by extending the performance of conventional circuitry and introducing radical new systems approaches. A variety of strategic MEMS structures including various cost-effective free-space optics and high-Q RF components are described, along with related practical implementation issues. These components are rapidly becoming essential for enabling the development of progressive new communications systems technologies including all-optical networks, and low cost multi-system wireless terminals and basestations.

Quantum coordinated multi-point communication based on entanglement swapping

NASA Astrophysics Data System (ADS)

Du, Gang; Shang, Tao; Liu, Jian-wei

2017-05-01

In a quantum network, adjacent nodes can communicate with each other point to point by using pre-shared Einsten-Podolsky-Rosen (EPR) pairs, and furthermore remote nodes can establish entanglement channels by using quantum routing among intermediate nodes. However, with the rapid development of quantum networks, the demand of various message transmission among nodes inevitably emerges. In order to realize this goal and extend quantum networks, we propose a quantum coordinated multi-point communication scheme based on entanglement swapping. The scheme takes full advantage of EPR pairs between adjacent nodes and performs multi-party entanglement swapping to transmit messages. Considering various demands of communication, all nodes work cooperatively to realize different message transmission modes, including one to many, many to one and one to some. Scheme analysis shows that the proposed scheme can flexibly organize a coordinated group and efficiently use EPR resources, while it meets basic security requirement under the condition of coordinated communication.

A Better Patient Experience Through Better Communication

Lang, Elvira V.

2012-01-01

The transformation of healthcare from a seller’s market to a consumer’s market has pushed the element of patient satisfaction into the forefront of various medical facility evaluation tools, including those used by Medicare when weighing reimbursement to hospitals for patient care. Research has identified good communication skills to be a key factor in ensuring better patient outcomes, and nurturing patient satisfaction. Because of the growing amount of money at stake for patients’ satisfaction with a facility, the communication skills of individual healthcare providers are bound to impact their employees' reimbursement, bonuses, and promotion options. Although the dangers of “poor communication,” are evident: “poor communication” is a primary reason for filing a law suit in >80% of cases (Avery, 1985). Identifying the characteristics of “good communication” has been difficult. One factor that adds to the confusion is that research has found some long accepted codes of professional communication protocol to actually be counterproductive. Another factor that adds to the uncertainty is that accurate interpretations of some communication events are counterintuitive. Fortunately it has been possible to extract observable, proven, and teachable “good communication” behaviors from large-scale trials in the radiology department. The resultant Comfort Talk™ approach to communication includes rapid rapport techniques, patient-centered talking styles, and use of hypnotic language. This article overviews some of the Comfort Talk™ approaches to patients interaction and provides operational summaries of a sampling of specific Comfort Talk™ communication techniques, which nurses, technologists, and other healthcare workers can implement in their own practices.

An experimental study of the emergence of human communication systems.

PubMed

Galantucci, Bruno

2005-09-10

The emergence of human communication systems is typically investigated via 2 approaches with complementary strengths and weaknesses: naturalistic studies and computer simulations. This study was conducted with a method that combines these approaches. Pairs of participants played video games requiring communication. Members of a pair were physically separated but exchanged graphic signals through a medium that prevented the use of standard symbols (e.g., letters). Communication systems emerged and developed rapidly during the games, integrating the use of explicit signs with information implicitly available to players and silent behavior-coordinating procedures. The systems that emerged suggest 3 conclusions: (a) signs originate from different mappings; (b) sign systems develop parsimoniously; (c) sign forms are perceptually distinct, easy to produce, and tolerant to variations. 2005 Lawrence Erlbaum Associates, Inc.

Communicating Genetic Risk Information for Common Disorders in the Era of Genomic Medicine

Lautenbach, Denise M.; Christensen, Kurt D.; Sparks, Jeffrey A.; Green, Robert C.

2013-01-01

Communicating genetic risk information in ways that maximize understanding and promote health is increasingly important given the rapidly expanding availability and capabilities of genomic technologies. A well-developed literature on risk communication in general provides guidance for best practices, including presentation of information in multiple formats, attention to framing effects, use of graphics, sensitivity to the way numbers are presented, parsimony of information, attentiveness to emotions, and interactivity as part of the communication process. Challenges to communicating genetic risk information include deciding how best to tailor it, streamlining the process, deciding what information to disclose, accepting that communications may have limited influence, and understanding the impact of context. Meeting these challenges has great potential for empowering individuals to adopt healthier lifestyles and improve public health, but will require multidisciplinary approaches and collaboration.

2013-04-01

In 2007 the Geospatial information Authority of Japan (GSI) and the Onsala Space Observatory (OSO) started a project aiming at determining the earth rotation angle, usually expressed as dUT1, in near real-time. In the beginning of this project dedicated one hour long one-baseline experiments were observed periodically using the VLBI stations Onsala (Sweden) and Tsukuba (Japan). The strategy is that the observed VLBI-data are sent in real-time via the international optical fibre backbone to the VLBI-correlator at Tsukuba where the data are correlated and analyzed in near-real time, producing ultra-rapid dUT1 results. An offline version of this strategy has been adopted in 2009 for the regular VLBI intensive series INT-2 involving Wettzell (Germany) and Tsukuba. Since March 2010 the INT-2 is using real-time e-transfer, too, and since June 2010 also automated analysis. Starting in 2009 the ultra-rapid approach was applied to regular 24 hour long VLBI-sessions that involve Tsukuba and Onsala, so that ultra-rapid dUT1 results can be produced already during ongoing VLBI-sessions. This strategy was successfully operated during the 15 days long CONT11 campaign. In 2011 the ultra-rapid strategy was extended to involve a network of VLBI-stations, so that not only dUT1 but also the polar motion components can be determined in near real-time. Initially, in November 2011 a dedicated three-station session was observed involving Onsala, Tsukuba and Hobart (Tasmania, Australia). In 2012 several regular 24 hour long IVS-sessions that involved Onsala, Tsukuba and HartRAO (South Africa) were operated with the ultra-rapid strategy, and in several cases also Hobart was added as a fourth station. For this project we use the new analysis software c5++ developed by the National Institute of Information and Communications Technology (NICT). In this presentation we give an overview of the UREOP-project, describe the recent developments, and discuss the obtained results.

A centralized electrocardiogram telemetry monitoring system (TMS) facilitates early identification of critical arrhythmias and acute medical decompensation. Timely intervention can only be performed if abnormalities are communicated rapidly to the direct caregiver. The study objectives were to measure effectiveness of bi-directional voice communication badges versus one-way alphanumeric pagers for telemetry alarm response and communication loop closure. A sequential observational pilot study of nursing response to TMS alarms compared communication technologies on four nursing units in a 1,061 bed tertiary care hospital with 264 TMS channels of telemetry over a 2-year period. Subsequently, the communication technologies were compared in a randomized fashion on a 68-bed progressive cardiac care unit. Caregivers were blinded to the protocol. All alarm responses were recorded during two periods using either pagers or voice communication devices. Alarm response time and closure of the communication loop were analyzed in a blinded fashion. The direct communication functionality of the badge significantly shortened the time to first contact, time to completion, and rate of closure of the communication loop in both the pilot and study phases. Median time to first contact with the communication badge was 0.5  min, compared to 1.6  min with pager communication (p < 0.0003). Communication loop closure was achieved in 100% of clinical alarms using the badge versus 19% with the pager (p < 0.0001). Communication badge technology reduced alarm time to first contact and completion as well as facilitated communication loop closures. Immediate two-way communication significantly impacted practice, alarm management, and resulted in faster bedside care.

Oxytocin is a neuropeptide known to influence how humans share material resources. Here we explore whether oxytocin influences how we share knowledge. We focus on two distinguishing features of human communication, namely the ability to select communicative signals that disambiguate the many-to-many mappings that exist between a signal's form and meaning, and adjustments of those signals to the presumed cognitive characteristics of the addressee ("audience design"). Fifty-five males participated in a randomized, double-blind, placebo controlled experiment involving the intranasal administration of oxytocin. The participants produced novel non-verbal communicative signals towards two different addressees, an adult or a child, in an experimentally-controlled live interactive setting. We found that oxytocin administration drives participants to generate signals of higher referential quality, i.e. signals that disambiguate more communicative problems; and to rapidly adjust those communicative signals to what the addressee understands. The combined effects of oxytocin on referential quality and audience design fit with the notion that oxytocin administration leads participants to explore more pervasively behaviors that can convey their intention, and diverse models of the addressees. These findings suggest that, besides affecting prosocial drive and salience of social cues, oxytocin influences how we share knowledge by promoting cognitive exploration.

Barritt, Brian; Bhasin, Kul; Eddy, Wesley; Matthews, Seth

2010-01-01

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

Creativity in clinical communication: from communication skills to skilled communication.

PubMed

Salmon, Peter; Young, Bridget

2011-03-01

Medical Education 2011: 45: 217-226 Objectives  The view that training in communication skills produces skilled communication is sometimes criticised by those who argue that communication is individual and intuitive. We therefore examine the validity of the concept of communication as a skill and identify alternative principles to underpin future development of this field. Methods  We critically examine research evidence about the nature of clinical communication, and draw from theory and evidence concerning education and evaluation, particularly in creative disciplines. Results  Skilled communication cannot be fully described using the concept of communication skills. Attempts to do so risk constraining and distorting pedagogical development in communication. Current education practice often masks the difficulties with the concept by introducing subjectivity into the definition and assessment of skills. As all clinical situations differ to some extent, clinical communication is inherently creative. Because it is rarely possible to attribute specific effects to specific elements of communication, communication needs to be taught and evaluated holistically. Conclusions  For communication teaching to be pedagogically and clinically valid in supporting the inherent creativity of clinical communication, it will need to draw from education theory and practice that have been developed in explicitly creative disciplines. © Blackwell Publishing Ltd 2011.

Rapid effects of estrogens on behavior: environmental modulation and molecular mechanisms.

Laredo, Sarah A; Villalon Landeros, Rosalina; Trainor, Brian C

2014-10-01

Estradiol can modulate neural activity and behavior via both genomic and nongenomic mechanisms. Environmental cues have a major impact on the relative importance of these signaling pathways with significant consequences for behavior. First we consider how photoperiod modulates nongenomic estrogen signaling on behavior. Intriguingly, short days permit rapid effects of estrogens on aggression in both rodents and song sparrows. This highlights the importance of considering photoperiod as a variable in laboratory research. Next we review evidence for rapid effects of estradiol on ecologically-relevant behaviors including aggression, copulation, communication, and learning. We also address the impact of endocrine disruptors on estrogen signaling, such as those found in corncob bedding used in rodent research. Finally, we examine the biochemical mechanisms that may mediate rapid estrogen action on behavior in males and females. A common theme across these topics is that the effects of estrogens on social behaviors vary across different environmental conditions. Copyright © 2014 Elsevier Inc. All rights reserved.

Regulation of tissue development and repair depends on communication between neighbouring cells. Recent advances in cell micro-contact printing and microfluidics have facilitated the in-vitro study of homotypic and heterotypic cell-cell interaction. Nonetheless, these techniques are still complicated to perform and as a result, are seldom used by biologists. We report here development of a temporarily sealed microfluidic stamping device which utilizes a novel valve design for patterning two adherent cell lines with well-defined interlacing configurations to study cell-cell interactions. We demonstrate post-stamping cell viability of >95%, the stamping of multiple adherent cell types, and the ability to control the seeded cell density. We also show viability, proliferation and migration of cultured cells, enabling analysis of co-culture boundary conditions on cell fate. We also developed an in-vitro model of endothelial and cardiac stem cell interactions, which are thought to regulate coronary repair after myocardial injury. The stamp is fabricated using microfabrication techniques, is operated with a lab pipettor and uses very low reagent volumes of 20 μl with cell injection efficiency of >70%. This easy-to-use device provides a general strategy for micro-patterning of multiple cell types and will be important for studying cell-cell interactions in a multitude of applications.

Innate cell communication kick-starts pathogen-specific immunity

2016-01-01

Innate cells are responsible for the rapid recognition of infection and mediate essential mechanisms of pathogen elimination, and also facilitate adaptive immune responses. We review here the numerous intricate interactions among innate cells that initiate protective immunity. The efficient eradication of pathogens depends on the coordinated actions of multiple cells, including innate cells and epithelial cells. Rather than acting as isolated effector cells, innate cells are in constant communication with other responding cells of the immune system, locally and distally. These interactions are critically important for the efficient control of primary infections as well for the development of ‘trained’ innate cells that facilitate the rapid elimination of homologous or heterologous infections.

Aviation continues to experience rapid growth. In regions such as the United States and Europe air traffic congestion is constraining operations, leading to major new efforts to develop methodologies and infrastructures to enable continued aviation growth through transformational air traffic management systems. Such a transformation requires better communications linking airborne and ground-based elements. Technologies for next-generation communications, the required capacities, frequency spectrum of operation, network interconnectivity, and global interoperability are now receiving increased attention. A number of major planning and development efforts have taken place or are in process now to define the transformed airspace of the future. These activities include government and industry led efforts in the United States and Europe, and by international organizations. This paper will review the features, approaches, and activities of several representative planning and development efforts, and identify the emerging global consensus on requirements of next generation aeronautical communications systems for air traffic control.

The next generation of military communications satellites may be designed as a fast packet-switched constellation of spacecraft able to withstand substantial bandwidth capacity fluctuation in the face of dynamic resource utilization and rapid environmental changes including jamming of communication frequencies and unstable weather phenomena. We are in the process of designing an integrated scheduling and execution tool which will aid in the analysis of the design parameters needed for building such a distributed system for nominal and battlefield communications. This paper discusses the design of such a system based on a temporal constraint posting planner/scheduler and a smart executive which can cope with a dynamic environment to make a more optimal utilization of bandwidth than the current circuit switched based approach.

Improvement of reliability in multi-interferometer-based counterfactual deterministic communication with dissipation compensation.

Liu, Chao; Liu, Jinhong; Zhang, Junxiang; Zhu, Shiyao

2018-02-05

The direct counterfactual quantum communication (DCQC) is a surprising phenomenon that quantum information can be transmitted without using any carriers of physical particles. The nested interferometers are promising devices for realizing DCQC as long as the number of interferometers goes to be infinity. Considering the inevitable loss or dissipation in practical experimental interferometers, we analyze the dependence of reliability on the number of interferometers, and show that the reliability of direct communication is being rapidly degraded with the large number of interferometers. Furthermore, we simulate and test this counterfactual deterministic communication protocol with a finite number of interferometers, and demonstrate the improvement of the reliability using dissipation compensation in interferometers.

Review, Selection and Installation of a Rapid Prototype Machine

McEndree, Caryl

2008-01-01

The objective of this paper is to impress upon the reader the benefits and advantages of investing in rapid prototyping (additive manufacturing) technology thru the procurement of one or two new rapid prototyping machines and the creation of a new Prototype and Model Lab at the Kennedy Space Center (KSC). This new resource will be available to all of United Space Alliance, LLC (USA), enabling engineers from around the company to pursue a more effective means of communication and design with our co-workers, and our customer, the National Aeronautics and Space Administration (NASA). The Rapid Protoyping/3D printing industry mirrors the transition the CAD industry made several years ago, when companies were trying to justify the expenditure of converting to a 3D based system from a 2D based system. The advantages of using a 3D system seemed to be outweighed by the cost it would take to convert not only legacy 2D drawings into 3D models but the training of personnel to use the 3D CAD software. But the reality was that when a 3D CAD system is employed, it gives engineers a much greater ability to conceive new designs and the ability to engineer new tools and products much more effectively. Rapid Prototyping (RP) is the name given to a host of related technologies that are used to fabricate physical objects directly from Computer Aided Design (CAD) data sources. These methods are generally similar to each other in that they add and bond materials in a layer wise-fashion to form objects, instead of machining away material. The machines used in Rapid Prototyping are also sometimes referred to as Rapid Manufacturing machines due to the fact that some of the parts fabricated in a RP machine can be used as the finished product. The name "Rapid Prototyping" is really a misnomer. It is much more than prototypes and it is not always rapid.

Plant signalling: the opportunities and dangers of chemical communication.

Adler, Frederick R

2011-04-23

The notion of chemical communication between plants and other organisms has gone from being viewed as a fringe idea to an accepted ecological phenomenon only recently. An Organized Oral Session at the August 2010 Ecological Society of America meeting in Pittsburgh examined the role of plant signalling both within and between plants, with speakers addressing the remarkably wide array of effects that plant signals have on plant physiology, species interactions and entire communities. In addition to the familiar way that plants communicate with mutualists like pollinators and fruit dispersers through both chemical and visual cues, speakers at this session described how plants communicate with themselves, with each other, with herbivores and with predators of those herbivores. These plant signals create a complex odour web superimposed upon the more classical food web itself, with its own dynamics in the face of exotic species and rapid community assembly and disassembly.

Twelve-month-old infants recognize that speech can communicate unobservable intentions.

Vouloumanos, Athena; Onishi, Kristine H; Pogue, Amanda

2012-08-07

Much of our knowledge is acquired not from direct experience but through the speech of others. Speech allows rapid and efficient transfer of information that is otherwise not directly observable. Do infants recognize that speech, even if unfamiliar, can communicate about an important aspect of the world that cannot be directly observed: a person's intentions? Twelve-month-olds saw a person (the Communicator) attempt but fail to achieve a target action (stacking a ring on a funnel). The Communicator subsequently directed either speech or a nonspeech vocalization to another person (the Recipient) who had not observed the attempts. The Recipient either successfully stacked the ring (Intended outcome), attempted but failed to stack the ring (Observable outcome), or performed a different stacking action (Related outcome). Infants recognized that speech could communicate about unobservable intentions, looking longer at Observable and Related outcomes than the Intended outcome when the Communicator used speech. However, when the Communicator used nonspeech, infants looked equally at the three outcomes. Thus, for 12-month-olds, speech can transfer information about unobservable aspects of the world such as internal mental states, which provides preverbal infants with a tool for acquiring information beyond their immediate experience.

Much of our knowledge is acquired not from direct experience but through the speech of others. Speech allows rapid and efficient transfer of information that is otherwise not directly observable. Do infants recognize that speech, even if unfamiliar, can communicate about an important aspect of the world that cannot be directly observed: a person’s intentions? Twelve-month-olds saw a person (the Communicator) attempt but fail to achieve a target action (stacking a ring on a funnel). The Communicator subsequently directed either speech or a nonspeech vocalization to another person (the Recipient) who had not observed the attempts. The Recipient either successfully stacked the ring (Intended outcome), attempted but failed to stack the ring (Observable outcome), or performed a different stacking action (Related outcome). Infants recognized that speech could communicate about unobservable intentions, looking longer at Observable and Related outcomes than the Intended outcome when the Communicator used speech. However, when the Communicator used nonspeech, infants looked equally at the three outcomes. Thus, for 12-month-olds, speech can transfer information about unobservable aspects of the world such as internal mental states, which provides preverbal infants with a tool for acquiring information beyond their immediate experience.

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.

A discussion of the potential use of rapid review approaches in nursing and midwifery research which presents a worked example from a study conducted to inform policy decision-making. Rapid reviews, which can be defined as outputs of a knowledge synthesis approach that involves modifying or omitting elements of a systematic review process due to limited time or resources, are becoming increasingly popular in health research. This paper provides guidance on how a rapid review can be undertaken and discusses the strengths and challenges of the approach. Data from a rapid review of the literature undertaken in 2015 is used as a worked example to highlight one method of undertaking a rapid review. Seeking evidence to inform health policy-making or evidence based practice is a process that can be limited by time constraints, making it difficult to conduct comprehensive systematic reviews. Rapid reviews provide a solution as they are a systematic method of synthesizing evidence quickly. There is no single best way to conduct a rapid review but researchers can ensure they are adhering to best practice by being systematic, having subject and methodological expertise on the review team, reporting the details of the approach they took, highlighting the limitations of the approach, engaging in good evidence synthesis and communicating regularly with end users, other team members and experts. © 2016 John Wiley & Sons Ltd.

Autonomous Spacecraft Communication Interface for Load Planning

Dever, Timothy P.; May, Ryan D.; Morris, Paul H.

2014-01-01

Ground-based controllers can remain in continuous communication with spacecraft in low Earth orbit (LEO) with near-instantaneous communication speeds. This permits near real-time control of all of the core spacecraft systems by ground personnel. However, as NASA missions move beyond LEO, light-time communication delay issues, such as time lag and low bandwidth, will prohibit this type of operation. As missions become more distant, autonomous control of manned spacecraft will be required. The focus of this paper is the power subsystem. For present missions, controllers on the ground develop a complete schedule of power usage for all spacecraft components. This paper presents work currently underway at NASA to develop an architecture for an autonomous spacecraft, and focuses on the development of communication between the Mission Manager and the Autonomous Power Controller. These two systems must work together in order to plan future load use and respond to unanticipated plan deviations. Using a nominal spacecraft architecture and prototype versions of these two key components, a number of simulations are run under a variety of operational conditions, enabling development of content and format of the messages necessary to achieve the desired goals. The goals include negotiation of a load schedule that meets the global requirements (contained in the Mission Manager) and local power system requirements (contained in the Autonomous Power Controller), and communication of off-plan disturbances that arise while executing a negotiated plan. The message content is developed in two steps: first, a set of rapid-prototyping "paper" simulations are preformed; then the resultant optimized messages are codified for computer communication for use in automated testing.

Proximate and ultimate aspects of acoustic and multimodal communication in butterflyfishes

NASA Astrophysics Data System (ADS)

Boyle, Kelly S.

Communication in social animals is shaped by natural selection on both sender and receiver. Diurnal butterflyfishes use a combination of visual cues like bright color patterns and motor pattern driven displays, acoustic communication, and olfactory cues that may advertise territorial behavior, facilitate recognition of individuals, and provide cues for courtship. This dissertation examines proximate and multimodal communication in several butterflyfishes, with an emphasis on acoustic communication which has recently garnered attention within the Chaetodontidae. Sound production in the genus Forcipiger involves a novel mechanism with synchronous contractions of opposing head muscles at the onset of sound emission and rapid cranial rotation that lags behind sound emission. Acoustic signals in F. flavissimus provide an accurate indicator of body size, and to a lesser extent cranial rotation velocity and acceleration. The closely related Hemitaurichthys polylepis produces rapid pulse trains of similar duration and spectral content to F. flavissimus, but with a dramatically different mechanism which involves contractions of hypaxial musculature at the anterior end of the swim bladder that occur with synchronous muscle action potentials. Both H. polylepis sonic and hypaxial trunk muscle fibers have triads at the z-line, but sonic fibers have smaller cross-sectional areas, more developed sarcoplasmic reticula, longer sarcomere lengths, and wider t-tubules. Sonic motor neurons are located along a long motor column entirely within the spinal cord and are composed of large and small types. Forcipiger flavissimus and F. longirostris are site attached and territorial, with F. flavissimus engaged in harem polygyny and F. longirostris in social monogamy. Both produce similar pulse sounds to conspecifics during territoriality that vary little with respect to communicative context. Chaetodon multicinctus can discriminate between mates and non-mate intruders, but require combined

TWT design requirements for 30/20 GHz digital communications' satellite

Stankiewicz, N.; Anzic, G.

1979-01-01

The rapid growth of communication traffic (voice, data, and video) requires the development of additional frequency bands before the 1990's. The frequencies currently in use for satellite communications at 6/4 GHz are crowded and demands for 14/12 GHz systems are increasing. Projections are that these bands will be filled to capacity by the late 1980's. The next higher frequency band allocated for satellite communications is at 30/20 GHz. For interrelated reasons of efficiency, power level, and system reliability criteria, a candidate for the downlink amplifier in a 30/20 GHz communications' satellite is a dual mode traveling wave tube (TWT) equipped with a highly efficient depressed collector. A summary is given of the analyses which determine the TWT design requirements. The overall efficiency of such a tube is then inferred from a parametric study and from experimental data on multistaged depressed collectors. The expected TWT efficiency at 4 dB below output saturation is 24 percent in the high mode and 22 percent in the low mode.

Acoustic communication in insect disease vectors

Vigoder, Felipe de Mello; Ritchie, Michael Gordon; Gibson, Gabriella; Peixoto, Alexandre Afranio

2013-01-01

Acoustic signalling has been extensively studied in insect species, which has led to a better understanding of sexual communication, sexual selection and modes of speciation. The significance of acoustic signals for a blood-sucking insect was first reported in the XIX century by Christopher Johnston, studying the hearing organs of mosquitoes, but has received relatively little attention in other disease vectors until recently. Acoustic signals are often associated with mating behaviour and sexual selection and changes in signalling can lead to rapid evolutionary divergence and may ultimately contribute to the process of speciation. Songs can also have implications for the success of novel methods of disease control such as determining the mating competitiveness of modified insects used for mass-release control programs. Species-specific sound “signatures” may help identify incipient species within species complexes that may be of epidemiological significance, e.g. of higher vectorial capacity, thereby enabling the application of more focussed control measures to optimise the reduction of pathogen transmission. Although the study of acoustic communication in insect vectors has been relatively limited, this review of research demonstrates their value as models for understanding both the functional and evolutionary significance of acoustic communication in insects.

Design and Verification of a Distributed Communication Protocol

Munoz, Cesar A.; Goodloe, Alwyn E.

2009-01-01

The safety of remotely operated vehicles depends on the correctness of the distributed protocol that facilitates the communication between the vehicle and the operator. A failure in this communication can result in catastrophic loss of the vehicle. To complicate matters, the communication system may be required to satisfy several, possibly conflicting, requirements. The design of protocols is typically an informal process based on successive iterations of a prototype implementation. Yet distributed protocols are notoriously difficult to get correct using such informal techniques. We present a formal specification of the design of a distributed protocol intended for use in a remotely operated vehicle, which is built from the composition of several simpler protocols. We demonstrate proof strategies that allow us to prove properties of each component protocol individually while ensuring that the property is preserved in the composition forming the entire system. Given that designs are likely to evolve as additional requirements emerge, we show how we have automated most of the repetitive proof steps to enable verification of rapidly changing designs.

Coherent Optical Communications: Historical Perspectives and Future Directions

NASA Astrophysics Data System (ADS)

Kikuchi, Kazuro

Coherent optical fiber communications were studied extensively in the 1980s mainly because high sensitivity of coherent receivers could elongate the unrepeated transmission distance; however, their research and development have been interrupted for nearly 20 years behind the rapid progress in high-capacity wavelength-division multiplexed (WDM) systems using erbium-doped fiber amplifiers (EDFAs). In 2005, the demonstration of digital carrier phase estimation in coherent receivers has stimulated a widespread interest in coherent optical communications again. This is due to the fact that the digital coherent receiver enables us to employ a variety of spectrally efficient modulation formats such as M-ary phase-shift keying (PSK) and quadrature amplitude modulation (QAM) without relying upon a rather complicated optical phase-locked loop. In addition, since the phase information is preserved after detection, we can realize electrical post-processing functions such as compensation for chromatic dispersion and polarization-mode dispersion in the digital domain. These advantages of the born-again coherent receiver have enormous potential for innovating existing optical communication systems. In this chapter, after reviewing the 20-year history of coherent optical communication systems, we describe the principle of operation of coherent detection, the concept of the digital coherent receiver, and its performance evaluation. Finally, challenges for the future are summarized.

Technical comparison of several global mobile satellite communications systems

NASA Astrophysics Data System (ADS)

Comparetto, Gary M.

The era of satellite-based mobile satellite communications (MSC) systems started with the first MARISAT satellite which was launched into a geostationary orbit over the Pacific Ocean in 1976 to provide communications between ships and shore stations. The combination of high cost and unacceptably large equipment has kept the space-based MSC systems from appealing to the wider market of personal mobile communications. The progress made over the last ten years, however, in digital voice processing, satellite technology, and component miniaturization has resulted in the viability of satellite-based mobile satellite communications systems to meet the growing market in personal mobile communications using handsets similar to those currently in use with land-based cellular systems. Three of the more mature LEO/MEO satellite systems are addressed in this paper including GLOBALSTAR, Iridium, and Odyssey. The system architectures of each system are presented along with a description of the satellite and user handset designs and the multiaccess techniques employed. It will be shown that, although a number of similarities exist among the system addressed, each system is unique in a variety of significant design areas. It is concluded that the technical feasibility of satellite-based mobile satellite communications systems seems to be secure. It will be challenging, however, for the vendors to actually develop and deploy these systems in a cost effective, timely, and reliable way that meets a continually evolving set of requirements based upon a rapidly changing technology base.

Evaluation and communication: using a communication audit to evaluate organizational communication.

PubMed

Hogard, Elaine; Ellis, Roger

2006-04-01

This article identifies a surprising dearth of studies that explicitly link communication and evaluation at substantive, theoretical, and methodological levels. A three-fold typology of evaluation studies referring to communication is proposed and examples given. The importance of organizational communication in program delivery is stressed and illustrative studies reviewed. It is proposed that organizational communication should be considered in all program evaluations and that this should be approached through communication audit. Communication audits are described with particular reference to established survey questionnaire instruments. Two case studies exemplify the use of such instruments in the evaluation of educational and social programs.

Rapid response, monitoring, and mitigation of induced seismicity near Greeley, Colorado

Yeck, William; Sheehan, A.F; Benz, Harley M.; Weingarten, Matthew; Nakai, J

2016-01-01

On 1 June 2014 (03:35 UTC), an Mw 3.2 earthquake occurred in Weld County, Colorado, a historically aseismic area of the Denver–Julesburg basin. Weld County is a prominent area of oil and gas development, including many high‐rate class II wastewater injection wells. In the days following the earthquake, the University of Colorado, with support from the U.S. Geological Survey and Incorporated Research Institutions for Seismology–Portable Array Seismic Studies of the Continental Lithosphere, rapidly deployed six seismic stations to characterize the seismicity associated with the 1 June earthquake (the Greeley sequence) and to investigate its possible connection to wastewater disposal. The spatial and temporal proximity of earthquakes to a high‐rate wastewater disposal well strongly suggests these earthquakes were induced. Scientific communication between the university, state agencies, and the energy industry led to rapid mitigation strategies to reduce the occurrence of further earthquakes. Mitigation efforts included implementing a temporary moratorium on injection at the well, cementing the bottom portion of the disposal well to minimize hydrologic connectivity between the disposal formation and the underlying crystalline basement, and subsequently allowing injection to resume at lower rates. Following the resumption of wastewater disposal, microseismicity was closely monitored for both increases in earthquake rate and magnitude. Following mitigation efforts, between 13 August 2014 and 29 December 2015, no earthquakes larger than M 1.5 occurred near the Greeley sequence. This study demonstrates that a detailed and rapid characterization of a seismic sequence in space and time relative to disposal, combined with collaboration and communication between scientists, regulators, and industry, can lead to objective and actionable mitigation efforts that potentially reduced the rate of earthquakes and the possible generation of larger earthquakes.

2003-01-01

Future science missions will require the use of multiple spacecraft with multiple sensor nodes autonomously responding and adapting to a dynamically changing space environment. The acquisition of random scientific events will require rapidly changing network topologies, distributed processing power, and a dynamic resource management strategy. Optimum utilization and configuration of spacecraft communications and navigation resources will be critical in meeting the demand of these stringent mission requirements. There are two important trends to follow with respect to NASA's (National Aeronautics and Space Administration) future scientific missions: the use of multiple satellite systems and the development of an integrated space communications network. Reconfigurable computing and communication systems may enable versatile adaptation of a spacecraft system's resources by dynamic allocation of the processor hardware to perform new operations or to maintain functionality due to malfunctions or hardware faults. Advancements in FPGA (Field Programmable Gate Array) technology make it possible to incorporate major communication and network functionalities in FPGA chips and provide the basis for a dynamically reconfigurable communication system. Advantages of higher computation speeds and accuracy are envisioned with tremendous hardware flexibility to ensure maximum survivability of future science mission spacecraft. This paper discusses the requirements, enabling technologies, and challenges associated with dynamically reconfigurable space communications systems.

Is the worldwide epidemic of obesity a communicable feature of globalization?

PubMed

Bornstein, S R; Ehrhart-Bornstein, M; Wong, M L; Licinio, J

2008-09-01

Globalization has a major impact on both economic and social determinants in public health. The current worldwide epidemic in obesity needs to be considered in the context of globalization as a communicable rather than non-communicable process. There is increasing evidence that global trends in lifestyle, eating behavior and cultural adaptation contribute to the rapid increase in obesity around the world. Thus, obesity may be defined as a "socially-contagious" feature of globalization. Furthermore, infectious agents are being identified that may cause obesity by central mechanisms or by modulating adipocyte function or at least by contributing to the chronic inflammatory milieu of the metabolic syndrome. Therefore, globalization may indeed form a critical platform for these pathogens to fuel the obesity epidemic. Understanding obesity in the light of globalization as a communicable disorder will allow outlining better avenues of prevention and treatment.

BACKGROUND The Hablamos Juntos—Together We Speak (HJ)—national demonstration project targeted the improvement of language access for Spanish-speaking Latinos in areas with rapidly growing Latino populations. The objective of HJ was to improve doctor-patient communication by increasing access to and quality of interpreter services for Spanish-speaking patients. OBJECTIVE To investigate how access to interpreters for adult Spanish-speaking Latinos is associated with ratings of doctor/office staff communication and satisfaction with care. DESIGN Cross-sectional cohort study. PATIENTS A total of 1,590 Spanish-speaking Latino adults from eight sites across the United States who participated in the outpatient HJ evaluation. MEASUREMENTS We analyzed two multi-item measures of doctor communication (4 items) and office staff helpfulness (2 items), and one global item of satisfaction with care by interpreter use. We performed regression analyses to control for patient sociodemographic characteristics, survey year, and clustering at the site of care. RESULTS Ninety-five percent of participants were born outside the US, 81% were females, and survey response rates ranged from 45% to 85% across sites. In this cohort of Spanish-speaking patients, those who needed and always used interpreters reported better experiences with care than their counterparts who needed but had interpreters unavailable. Patients who always used an interpreter had better adjusted ratings of doctor communication [effect size (ES = 0.51)], office staff helpfulness (ES = 0.37), and satisfaction with care (ES = 0.37) than patients who needed but did not always use an interpreter. Patients who needed and always used interpreters also reported better experiences with care in all three domains measured [doctor communication (ES = 0.30), office staff helpfulness (ES = 0.21), and satisfaction with care (ES = 0.23)] than patients who did not need interpreters. CONCLUSIONS Among adult

2017-08-01

Currently, wide bandwidth signal dissemination along with low latency is a leading requisite in various applications. Free space optical wireless communication has introduced as a realistic technology for bridging the gap in present high data transmission fiber connectivity and as a provisional backbone for rapidly deployable wireless communication infrastructure. The manuscript highlights on the implementation of 10Gbps SAC-OCDMA FSO communications using modified two dimensional Golomb code (2D MGC) that possesses better auto correlation, minimum cross correlation and high cardinality. A comparison based on pseudo orthogonal (PSO) matrix code and modified two dimensional Golomb code (2D MGC) is developed in the proposed SAC OCDMA-FSO communication module taking different parameters into account. The simulative outcome signifies that the communication radius is bounded by the multiple access interference (MAI). In this work, a comparison is made in terms of bit error rate (BER), and quality factor (Q) based on modified two dimensional Golomb code (2D MGC) and PSO matrix code. It is observed that the 2D MGC yields better results compared to the PSO matrix code. The simulation results are validated using optisystem version 14.

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

Bernard, E. N.; Behn, R. R.; Hebenstreit, G. T.; Gonzalez, F. I.; Krumpe, P.; Lander, J. F.; Lorca, E.; McManamon, P. M.; Milburn, H. B.

Rapid onset natural hazards have claimed more than 2.8 million lives worldwide in the past 20 years. This category includes such events as earthquakes, landslides, hurricanes, tornados, floods, volcanic eruptions, wildfires, and tsunamis. Effective hazard mitigation is particularly difficult in such cases, since the time available to issue warnings can be very short or even nonexistent. This paper presents the concept of a local warning system that exploits and integrates the existing technologies of risk evaluation, environmental measurement, and telecommunications. We describe Project THRUST, a successful implementation of this general, systematic approach to tsunamis. The general approach includes pre-event emergency planning, real-time hazard assessment, and rapid warning via satellite communication links.

To investigate what and how medication information is communicated during handover interactions in specialty hospital settings. Effective communication about patients' medications between health professionals and nurses at handover is vital for the delivery of safe continuity of care. An exploratory qualitative design and observational study. Participant observation was undertaken at a metropolitan Australian public hospital in four specialty settings: cardiothoracic care, intensive care, emergency care and oncology care. A medication communication model was applied to the data and thematic analysis was performed. Over 130 hours of observational data were collected. In total, 185 (predominately nursing) handovers were observed across the four specialty settings involving 37 nurse participants. Health professionals communicated partial details of patients' medication regimens, by focusing on auditing the medication administration record, and through the handover approach employed. Gaps in medication information at handover were evident as shown by lack of communication about detailed and specific medication content. Incoming nurses rarely posed questions about medications at handover. Handover interactions contained restricted and incomplete medication information. Improving the transparency, completeness and accuracy of medication communication is vital for optimising patient safety and quality of care in specialty practice settings. For nurses to make informed and rapid decisions regarding appropriate patient care, information about all types of prescribed medications is essential, which is communicated in an explicit and clear way.

NASA's DEVELOP National Program conducts rapid feasibility projects that enable the future workforce and current decision makers to collaborate and build capacity to use Earth science data to enhance environmental management and policy. The program communicates its results and applications to a broad spectrum of audiences through a variety of methods: "virtual poster sessions" that engage the general public through short project videos and interactive dialogue periods, a "Campus Ambassador Corps" that communicates about the program and its projects to academia, scientific and policy conference presentations, community engagement activities and end-of-project presentations, project "hand-offs" providing results and tools to project partners, traditional publications (both gray literature and peer-reviewed), an interactive website project gallery, targeted brochures, and through multiple social media venues and campaigns. This presentation will describe the various methods employed by DEVELOP to communicate the program's scientific outputs, target audiences, general statistics, community response and best practices.

Virtual target tracking (VTT) as applied to mobile satellite communication networks

NASA Astrophysics Data System (ADS)

Amoozegar, Farid

1999-08-01

Traditionally, target tracking has been used for aerospace applications, such as, tracking highly maneuvering targets in a cluttered environment for missile-to-target intercept scenarios. Although the speed and maneuvering capability of current aerospace targets demand more efficient algorithms, many complex techniques have already been proposed in the literature, which primarily cover the defense applications of tracking methods. On the other hand, the rapid growth of Global Communication Systems, Global Information Systems (GIS), and Global Positioning Systems (GPS) is creating new and more diverse challenges for multi-target tracking applications. Mobile communication and computing can very well appreciate a huge market for Cellular Communication and Tracking Devices (CCTD), which will be tracking networked devices at the cellular level. The objective of this paper is to introduce a new concept, i.e., Virtual Target Tracking (VTT) for commercial applications of multi-target tracking algorithms and techniques as applied to mobile satellite communication networks. It would be discussed how Virtual Target Tracking would bring more diversity to target tracking research.

Rapid response to the onset of volcanic activity allows for the early assessment of hazard and risk [Tilling, 1989]. Data from remote volcanoes and volcanoes in countries with poor communication infrastructure can only be obtained via remote sensing [Harris et al., 2000]. By linking notifications of activity from ground-based and spacebased systems, these volcanoes can be monitored when they erupt.Over the last 18 months, NASA's Jet Propulsion Laboratory (JPL) has implemented a Volcano Sensor Web (VSW) in which data from ground-based and space-based sensors that detect current volcanic activity are used to automatically trigger the NASA Earth Observing 1 (EO-1) spacecraft to make highspatial-resolution observations of these volcanoes.

New computer and communications environments for light armored vehicles

NASA Astrophysics Data System (ADS)

Rapanotti, John L.; Palmarini, Marc; Dumont, Marc

2002-08-01

Light Armoured Vehicles (LAVs) are being developed to meet the modern requirements of rapid deployment and operations other than war. To achieve these requirements, passive armour is minimized and survivability depends more on sensors, computers and countermeasures to detect and avoid threats. The performance, reliability, and ultimately the cost of these components, will be determined by the trends in computing and communications. These trends and the potential impact on DAS (Defensive Aids Suite) development were investigated and are reported in this paper. Vehicle performance is affected by communication with other vehicles and other ISTAR (Intelligence, Surveillance, Target Acquisition and Reconnaissance) battlefield assets. This investigation includes the networking technology Jini developed by SUN Microsystems, which can be used to interface the vehicle to the ISTAR network. VxWorks by Wind River Systems, is a real time operating system designed for military systems and compatible with Jini. Other technologies affecting computer hardware development include, dynamic reconfiguration, hot swap, alternate pathing, CompactPCI, and Fiber Channel serial communication. To achieve the necessary performance at reasonable cost, and over the long service life of the vehicle, a DAS should have two essential features. A fitted for, but not fitted with approach will provide the necessary rapid deployment without a need to equip the entire fleet. With an expected vehicle service life of 50 years, 5-year technology upgrades can be used to maintain vehicle performance over the entire service life. A federation of modules instead of integrated fused sensors will provide the capability for incremental upgrades and mission configurability. A plug and play capability can be used for both hardware and expendables.

Dynamics of Gut-Brain Communication Underlying Hunger.

PubMed

Beutler, Lisa R; Chen, Yiming; Ahn, Jamie S; Lin, Yen-Chu; Essner, Rachel A; Knight, Zachary A

2017-10-11

Communication between the gut and brain is critical for homeostasis, but how this communication is represented in the dynamics of feeding circuits is unknown. Here we describe nutritional regulation of key neurons that control hunger in vivo. We show that intragastric nutrient infusion rapidly and durably inhibits hunger-promoting AgRP neurons in awake, behaving mice. This inhibition is proportional to the number of calories infused but surprisingly independent of macronutrient identity or nutritional state. We show that three gastrointestinal signals-serotonin, CCK, and PYY-are necessary or sufficient for these effects. In contrast, the hormone leptin has no acute effect on dynamics of these circuits or their sensory regulation but instead induces a slow modulation that develops over hours and is required for inhibition of feeding. These findings reveal how layers of visceral signals operating on distinct timescales converge on hypothalamic feeding circuits to generate a central representation of energy balance.

RAPID COMMUNICATIONS: Long-distance quantum teleportation assisted with free-space entanglement distribution

NASA Astrophysics Data System (ADS)

Ren, Ji-Gang; Yang, Bin; Yi, Zhen-Huan; Zhou, Fei; Chen, Kai; Peng, Cheng-Zhi; Pan, Jian-Wei

2009-08-01

Faithful long-distance quantum teleportation necessitates prior entanglement distribution between two communicated locations. The particle carrying on the unknown quantum information is then combined with one particle of the entangled states for Bell-state measurements, which leads to a transfer of the original quantum information onto the other particle of the entangled states. However in most of the implemented teleportation experiments nowadays, the Bell-state measurements are performed even before successful distribution of entanglement. This leads to an instant collapse of the quantum state for the transmitted particle, which is actually a single-particle transmission thereafter. Thus the true distance for quantum teleportation is, in fact, only in a level of meters. In the present experiment we design a novel scheme which has overcome this limit by utilizing fiber as quantum memory. A complete quantum teleportation is achieved upon successful entanglement distribution over 967 meters in public free space. Active feed-forward control techniques are developed for real-time transfer of quantum information. The overall experimental fidelities for teleported states are better than 89.6%, which signify high-quality teleportation.

FAST TRACK COMMUNICATION Quantum entanglement: the unitary 8-vertex braid matrix with imaginary rapidity

Chakrabarti, Amitabha; Chakraborti, Anirban; Jedidi, Aymen

2010-12-01

We study quantum entanglements induced on product states by the action of 8-vertex braid matrices, rendered unitary with purely imaginary spectral parameters (rapidity). The unitarity is displayed via the 'canonical factorization' of the coefficients of the projectors spanning the basis. This adds one more new facet to the famous and fascinating features of the 8-vertex model. The double periodicity and the analytic properties of the elliptic functions involved lead to a rich structure of the 3-tangle quantifying the entanglement. We thus explore the complex relationship between topological and quantum entanglement.

Communication in cancer care: psycho-social, interactional, and cultural issues. A general overview and the example of India.

Communication is a core aspect of psycho-oncology care. This article examines key psychosocial, cultural, and technological factors that affect this communication. Drawing from advances in clinical work and accumulating bodies of empirical evidence, the authors identify determining factors for high quality, efficient, and sensitive communication and support for those affected by cancer. Cancer care in India is highlighted as a salient example. Cultural factors affecting cancer communication in India include beliefs about health and illness, societal values, integration of spiritual care, family roles, and expectations concerning disclosure of cancer information, and rituals around death and dying. The rapidly emerging area of e-health significantly impacts cancer communication and support globally. In view of current globalization, understanding these multidimensional psychosocial, and cultural factors that shape communication are essential for providing comprehensive, appropriate, and sensitive cancer care.

Leader-Follower Formation Control of UUVs with Model Uncertainties, Current Disturbances, and Unstable Communication

PubMed Central

Yan, Zheping; Xu, Da; Chen, Tao; Zhang, Wei; Liu, Yibo

2018-01-01

Unmanned underwater vehicles (UUVs) have rapidly developed as mobile sensor networks recently in the investigation, survey, and exploration of the underwater environment. The goal of this paper is to develop a practical and efficient formation control method to improve work efficiency of multi-UUV sensor networks. Distributed leader-follower formation controllers are designed based on a state feedback and consensus algorithm. Considering that each vehicle is subject to model uncertainties and current disturbances, a second-order integral UUV model with a nonlinear function is established using the state feedback linearized method under current disturbances. For unstable communication among UUVs, communication failure and acoustic link noise interference are considered. Two-layer random switching communication topologies are proposed to solve the problem of communication failure. For acoustic link noise interference, accurate representation of valid communication information and noise stripping when designing controllers is necessary. Effective communication topology weights are designed to represent the validity of communication information interfered by noise. Utilizing state feedback and noise stripping, sufficient conditions for design formation controllers are proposed to ensure UUV formation achieves consensus under model uncertainties, current disturbances, and unstable communication. The stability of formation controllers is proven by the Lyapunov-Razumikhin theorem, and the validity is verified by simulation results. PMID:29473919

Who's talking? Communication and the casual/part-time nurse: a literature review.

PubMed

Batch, Mary; Barnard, Alan; Windsor, Carol

2009-08-01

The rapidly evolving nursing working environment has seen the increased use of flexible non standard employment, including part-time, casual and itinerate workers. Evidence suggests that the nursing workforce has been at the forefront of the flexibility push which has seen the appearance of a dual workforce and marginalization of part-time and casual workers by their full-time peers and managers. The resulting fragmentation has meant that effective communication management has become difficult. Additionally, it is likely that poor organisational communication exacerbated by the increased use of non standard staff, is a factor underlying current discontent in the nursing industry and may impact on both recruitment and retention problems as well as patient outcomes. This literature review explores the relationship between the increasing casualisation of the nursing workforce and, among other things, the communication practices of nurses within healthcare organisations.

Bu, Youjun; Zhang, Chuanhao; Jiang, YiMing; Zhang, Zhen

2016-10-01

With the network scales rapidly and new network applications emerge frequently, bandwidth supply for today's Internet could not catch up with the rapid increasing requirements. Unfortunately, irrational using of network sources makes things worse. Actual network deploys single-next-hop optimization paths for data transmission, but such "best effort" model leads to the imbalance use of network resources and usually leads to local congestion. On the other hand Multi-path routing can use the aggregation bandwidth of multi paths efficiently and improve the robustness of network, security, load balancing and quality of service. As a result, multi-path has attracted much attention in the routing and switching research fields and many important ideas and solutions have been proposed. This paper focuses on implementing the parallel transmission of multi next-hop data, balancing the network traffic and reducing the congestion. It aimed at exploring the key technologies of the multi-path communication network, which could provide a feasible academic support for subsequent applications of multi-path communication networking. It proposed a novel multi-path algorithm based on node potential in the network. And the algorithm can fully use of the network link resource and effectively balance network link resource utilization.

2006-01-01

Simulations and modeling of surface-based communications networks provides a rapid and cost effective means of requirement analysis, protocol assessments, and tradeoff studies. Robust testing in especially important for exploration systems, where the cost of deployment is high and systems cannot be easily replaced or repaired. However, simulation of the envisioned exploration networks cannot be achieved using commercial off the shelf network simulation software. Models for the nonstandard, non-COTS protocols used aboard space systems are not readily available. This paper will address the simulation of realistic scenarios representative of the activities which will take place on the surface of the Moon, including selection of candidate network architectures, and the development of an integrated simulation tool using OPNET modeler capable of faithfully modeling those communications scenarios in the variable delay, dynamic surface environments. Scenarios for exploration missions, OPNET development, limitations, and simulations results will be provided and discussed.

The Use of Social Networking Sites (SNSs) in Health Communication Campaigns: Review and Recommendations.

PubMed

Shi, Jingyuan; Poorisat, Thanomwong; Salmon, Charles T

2018-01-01

The past decade has witnessed a rapid increase in the use of Social Networking Sites (SNSs) in health communication campaigns seeking to achieve an ambitious range of health-related impacts. This article provides a review of 40 studies and research protocols, with a focus on two key factors that differentiate SNSs from more traditional health communication approaches of the past. The first is the potential dualism between message sender and receiver, in which receivers become receiver-sources who forward and amplify the content and reach of health messages. The second is the potential dualism between message and message impact, in which the act of forwarding and modifying messages by receiver-sources itself becomes a measure of message impact. Each of these dualisms has implications for the design and evaluation of contemporary health communication campaigns. The review concludes with a series of observations and recommendations for future health communication research.

Revisiting Communicative Competence in Augmentative and Alternative Communication.

PubMed

Tsai, Meng-Ju

2016-01-01

This tutorial paper is to explore the novel nature of communicative competence in augmentative and alternative communication (AAC) practice by comparing it to communicative competence in naturally verbal dyadic communication. This paper first reviews the four domains of communicative competence in AAC practice. Second, it examines competence in dyadic communications between naturally verbal people without disabilities, deriving new insights and using these to analyze the evolution of communicative competence in AAC practice. Communicative competence in AAC practice should be reconceptualized from a new perspective as dyadic, learned, co-constructed, and of relative value, ascertained through performance. In the past decades, the study of communicative competence in AAC practice has primarily focused on individual persons who use AAC. However, the conceptualization of communicative competence should shift away from an individualized construct toward a dyadic construct. This leads to a discussion of potential implications and future research directions. This paper might offer AAC researchers and practitioners an opportunity to deepen their understanding of communicative competence and promote more positive outcomes for people who use AAC. © 2017 S.

2003-01-01

Communication theory based analysis sheds new light on the use of health telematics. This analysis of structures in electronic medical communication shows communicative structures with special features. Current and evolving telemedical applications are analyzed. The methodology of communicational theory (focusing on linguistic pragmatics) is used to compare it with its conventional counterpart. The semiotic model, the roles of partners, the respective message and their relation are discussed. Channels, sender, addressee, and other structural roles are analyzed for different types of electronic medical communication. The communicative processes are shown as mutual, rational action towards a common goal. The types of communication/texts are analyzed in general. Furthermore the basic communicative structures of medical education via internet are presented with their special features. The analysis shows that electronic medical communication has special features compared to everyday communication: A third participant role often is involved: the patient. Messages often are addressed to an unspecified partner or to an unspecified partner within a group. Addressing in this case is (at least partially) role-based. Communication and message often directly (rather than indirectly) influence actions of the participants. Communication often is heavily regulated including legal implications like liability, and more. The conclusion from the analysis is that the development of telemedical applications so far did not sufficiently take communicative structures into consideration. Based on these results recommendations for future developments of telemedical applications/services are given.

Caring for women with gynecologic malignancies requires multidisciplinary communication and coordination across multiple providers. This article discusses a rapid review of the literature on characteristics of care coordination for gynecologic malignancies. Five electronic databases (from inception through March 2015) were searched for empirical studies on coordinated care models for female adults with gynecologic malignancies. A single reviewer extracted and synthesized information on how care was coordinated, how care teams made decisions, who performed what tasks, how care teams communicated information to coordinate care, and potential impact of the characteristic on delivering coordinated care. From 26 included studies, predominant characteristics of coordinated care were identified: multidisciplinary teams, patient navigators, scheduled follow-ups, survivorship care plans, and colocated services. Decision-making was best documented for studies that utilized teams that had periodic scheduled meetings with set agendas and consistent procedures. Providers' roles in coordinating care were numerous, reflecting professional backgrounds: oncologists had most authority in making treatment decisions; radiologists and pathologists shared vital biomedical information; and nurses coordinated care and communicated with patients. Communication tools and strategies across studies included having shared medical records, integrated treatment plans, and telephone-based or teleconferencing communication. There was limited information available on the impact of characteristics and accompanying strategies or tools. Several characteristics of care coordination models for gynecologic cancers have been published in the literature. Further investigation is needed to understand the relative effectiveness of these ways to coordinate care.

In the global effort to eliminate lymphatic filariasis (LF), rapid field-applicable tests are useful tools that will allow on-site testing to be performed in remote places and the results to be obtained rapidly. Exclusive reliance on the few existing tests may jeopardize the progress of the LF elimination program, thus the introduction of other rapid tests would be useful to address this issue. Two new rapid immunochromatographic IgG4 cassette tests have been produced, namely WB rapid and panLF rapid, for detection of bancroftian filariasis and all three species of lymphatic filaria respectively. WB rapid was developed using BmSXP recombinant antigen, while PanLF rapid was developed using BmR1 and BmSXP recombinant antigens. A total of 165 WB rapid and 276 panLF rapid tests respectively were evaluated at USM and the rest were couriered to another university in Malaysia (98 WB rapid, 129 panLF rapid) and to universities in Indonesia (56 WB rapid, 62 panLF rapid), Japan (152 of each test) and India (18 of each test) where each of the tests underwent independent evaluations in a blinded manner. The average sensitivities of WB rapid and panLF rapid were found to be 97.6% (94%–100%) and 96.5% (94%–100%) respectively; while their average specificities were both 99.6% (99%–100%). Thus this study demonstrated that both the IgG4 rapid tests were highly sensitive and specific, and would be useful additional tests to facilitate the global drive to eliminate this disease.

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

PubMed

Muturi, Nancy

2005-01-01

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

Centralized vs. Decentralized Nursing Stations: An Evaluation of the Implications of Communication Technologies in Healthcare.

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.

Investigating effects of communications modulation technique on targeting performance

One of the key challenges facing the global war on terrorism (GWOT) and urban operations is the increased need for rapid and diverse information from distributed sources. For users to get adequate information on target types and movements, they would need reliable data. In order to facilitate reliable computational intelligence, we seek to explore the communication modulation tradeoffs affecting information distribution and accumulation. In this analysis, we explore the modulation techniques of Orthogonal Frequency Division Multiplexing (OFDM), Direct Sequence Spread Spectrum (DSSS), and statistical time-division multiple access (TDMA) as a function of the bit error rate and jitter that affect targeting performance. In the analysis, we simulate a Link 16 with a simple bandpass frequency shift keying (PSK) technique using different Signal-to-Noise ratios. The communications transfer delay and accuracy tradeoffs are assessed as to the effects incurred in targeting performance.

Purpose To determine the perceptions of people with complex communication needs (CCN) and business staff regarding the uses and functionality of a mobile application to aid communication access. Method A qualitative study using thematic analysis of transcripts and field notes from focus groups and interviews of 19 people with CCN and nine business staff. Results Four themes and 10 subthemes were drawn from the data. Themes highlighted the desire for: increased communication strategies to support customer interactions, increased access to information, functionality of a mobile application to increase its utility, and preferred technical and visual features of mobile applications. Conclusion People with CCN and business staff perceived a mobile application as a useful tool to aid communication access. This research highlighted the importance of facilitating strategies to communicative interactions and information in the community as the fundamental goal of a mobile application developed to support communication access. Implications for Rehabilitation Mobile applications are widely accepted and used in modern customer service industries and have been identified as tools to increase communication access for people with complex communication needs (CCN). People with CCN identified accessibility, presentation, and customisation as important features of mobile applications for communication access. The diversity of user preferences and needs, and the rapid development of new technologies limit the applicability of a single design for mobile applications for people with CCN. People with CCN should be involved in application design and development. A mobile application for communication access would support customer-business interactions as well as enable more accessible information sharing about disability needs and services.

Trichoderma species are widely used as production hosts for industrial enzymes. Identification of Trichoderma species requires a complex molecular biology based identification involving amplification and sequencing of multiple genes. Industrial laboratories are required to run identification tests repeatedly in cell banking procedures and also to prove absence of production host in the product. Such demands can be fulfilled by a brief method which enables confirmation of strain identity. This communication describes one step identification method for two common Trichoderma species; T. citrinoviride and T. reesei, based on identification of polymorphic region in the nucleotide sequence of translation elongation factor 1 alpha. A unique forward primer and common reverse primer resulted in 153 and 139 bp amplicon for T. citrinoviride and T. reesei, respectively. Simplification was further introduced by using mycelium as template for PCR amplification. Method described in this communication allows rapid, one step identification of two Trichoderma species.

The rapid development of new media has exacerbated the complexity of urban street space’s information interaction. With the influence of the immersion communication, the streetscape has constructed a special scene like ‘media convergence’, which has brought a huge challenge for maintaining the urban streetscape order. The Spatial Visual Communication Research Method which should break the limitation of the traditional aesthetic space research, can provide a brand new prospect for this phenomenon research. This study aims to analyze and summarize the communication characteristics of new media and its context, which will be helpful for understanding the social meaning within the order change of the street’s spatial and physical environment.

Control and Non-Payload Communications Links for Integrated Unmanned Aircraft Operations

2012-01-01

Technology for unmanned aircraft has advanced so rapidly in recent years that many new applications to public and commercial use are being proposed and implemented. In many countries, emphasis is now being placed on developing the means to allow unmanned aircraft to operate within non-segregated airspace along with commercial, cargo and other piloted and passenger-carrying aircraft.In the U.S., Congress has mandated that the Federal Aviation Administration reduce and remove restrictions on unmanned aircraft operations in a relatively short time frame. To accomplish this, a number of technical and regulatory hurdles must be overcome. A key hurdle involve the communications link connecting the remote pilot located at a ground control station with the aircraft in the airspace, referred to as the Control and Non-Payload Communications (CNPC) link. This link represents a safety critical communications link, and thus requires dedicated and protected aviation spectrum as well as national and international standards defining the operational requirements the CNPC system. The CNPC link must provide line-of-site (LOS) communications, primarily through a ground-based communication system, and beyond-line-of-sight (BLOS) communication achieved using satellite communications. In the U.S., the National Aeronautics and Space Administration (NASA) is charged with providing the technical body of evidence to support spectrum allocation requirements and national and international standards development for the CNPC link. This paper provides a description of the CNPC system, an overview of NASA's CNPC project, and current results in technology assessment, air-ground propagation characterization, and supporting system studies and analyses will be presented.

As e-mail and other forms of electronic communication increase in popularity, it is important for dental schools to consider a curriculum that prepares their graduates to understand and apply effective electronic communication strategies to their patients. Reflecting this shift in communication behavior, the American Medical Association has developed specific e-mail communication guidelines. Some behavioral examples in these guidelines include protecting patients' protected health information (PHI), ensuring proper record keeping, and using professional, courteous, and understandable language. In this study, a sample of first- and fourth-year dental students (n=160) at the University of Pittsburgh School of Dental Medicine participated in an assignment assessing their patient-provider e-mail communication skills. A rubric was used to evaluate and compare the data between dental student classes. The results reveal a generalized lack of compliance with several of these guidelines by both classes (e.g., failure to protect PHI), despite efforts to expose students to these concepts in the curriculum. In an effort to train emerging dentists to function in a rapidly changing technological environment, these findings suggest a need for growth and development of curricula and perhaps guidelines/recommendations for behavioral competencies regarding dental students' use of electronic communication in the patient care environment.

In order to enhance patient safety during resuscitation of critically ill patients, we need to optimize team communication and enhance team situational awareness but little is known about resuscitation team communication patterns. The objective of this study is to understand how teams communicate during resuscitation; specifically to assess for a shared mental model (organized understanding of a team's relationships) and information needs. We triangulated 3 methods to evaluate resuscitation team communication at a tertiary care academic trauma center: (1) interviews; (2) simulated resuscitation observations; (3) live resuscitation observations. We interviewed 18 resuscitation team members about shared mental models, roles and goals of team members and procedural expectations. We observed 30 simulated resuscitation video recordings and documented the timing, source and destination of communication and the information category. We observed 12 live resuscitations in the emergency department and recorded baseline characteristics of the type of resuscitations, nature of teams present and type and content of information exchanges. The data were analyzed using a qualitative communication analysis method. We found that resuscitation team members described a shared mental model. Respondents understood the roles and goals of each team member in order to provide rapid, efficient and life-saving care with an overall need for situational awareness. The information flow described in the interviews was reflected during the simulated and live resuscitations with the most responsible physician and charting nurse being central to team communication. We consolidated communicated information into six categories: (1) time; (2) patient status; (3) patient history; (4) interventions; (5) assistance and consultations; 6) team members present. Resuscitation team members expressed a shared mental model and prioritized situational awareness. Our findings support a need for cognitive aids to

Water plays an important role in controlling chemical reactions and bioactivities. For example, water transportation through water channels in a biomembrane is a key factor in bioactivities. However, molecular-level mechanisms of water transportation are as yet unknown. Here, we investigate water transportation through narrow and wide one-dimensional (1D) channels on the basis of water-vapor adsorption rates and those determined by molecular dynamics simulations. We observed that water in narrow 1D channels was transported 3-5 times faster than that in wide 1D channels, although the narrow 1D channels provide fewer free nanospaces for water transportation. This rapid transportation is attributed to the formation of fewer hydrogen bonds between water molecules adsorbed in narrow 1D channels. The water-transportation mechanism provides the possibility of rapid communication through 1D channels and will be useful in controlling reactions and activities in water systems.

Communicating treatment risks and benefits to patients and their carers is central to clinical practice in modern healthcare. We investigated the challenges of risk communication by clinicians offering thrombolytic therapy for hyperacute stroke where treatment must be administered rapidly to maximise benefit. Semistructured interviews with 13 clinicians from three acute stroke units involved in decision making and/or information provision about thrombolysis. We report on clinicians' accounts of communicating risks and benefits to patients and carers. Framework analysis was employed. We identified the major challenges facing clinicians in communicating risk in this context that is, disease complexity, patients' capacity and time constraints, and communicating quality of life after stroke. We found significant variation in the data on risks and benefits that clinicians provide, and ways these were communicated to patients. Clinicians' communication strategies varied and included practices such as: a phased approach to communicating information, being responsive to the patient and family and documenting information they gave to patients. Risk communication about thrombolysis involves complex uncertainties. We elucidate the challenges of effective risk communication in a hyperacute setting and identify the issues regarding variation in risk communication and the use of less effective formats for the communication of numerical risks and benefits. The paper identifies good practice, such as the phased transfer of information over the care pathway, and ways in which clinicians might be supported to overcome challenges. This includes standardised risk and benefit information alongside appropriate personalisation of risk communication. Effective risk communication in emergency settings requires presentation of high-quality data which is amenable to tailoring to individual patients' circumstances. It necessitates clinical skills development supported by personalised risk

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

This article reports on a resident-led quality improvement program to improve communication between inpatient internal medicine residents and their patients' primary care physicians (PCPs). The program included education on care transitions, standardization of documentation, audit and feedback of documented PCP communication rates with public reporting of performance, rapid-cycle data analysis and improvement projects, and a financial incentive. At baseline, PCP communication was documented in 55% of patients; after implementation of the intervention, communication was documented in 89.3% (2477 of 2772) of discharges during the program period. The program was associated with a significant increase in referring PCP satisfaction with communication at hospital admission (baseline, 27.7% "satisfied" or "very satisfied"; postintervention, 58.2%; P < .01) but not at discharge (baseline, 14.9%; postintervention, 21.8%; P = .41). Residents cited the importance of PCP communication for patient care and audit and feedback of their performance as the principal drivers of their engagement in the project.

Real-time visual communication to aid disaster recovery in a multi-segment hybrid wireless networking system

2012-06-01

When natural disasters or other large-scale incidents occur, obtaining accurate and timely information on the developing situation is vital to effective disaster recovery operations. High-quality video streams and high-resolution images, if available in real time, would provide an invaluable source of current situation reports to the incident management team. Meanwhile, a disaster often causes significant damage to the communications infrastructure. Therefore, another essential requirement for disaster management is the ability to rapidly deploy a flexible incident area communication network. Such a network would facilitate the transmission of real-time video streams and still images from the disrupted area to remote command and control locations. In this paper, a comprehensive end-to-end video/image transmission system between an incident area and a remote control centre is proposed and implemented, and its performance is experimentally investigated. In this study a hybrid multi-segment communication network is designed that seamlessly integrates terrestrial wireless mesh networks (WMNs), distributed wireless visual sensor networks, an airborne platform with video camera balloons, and a Digital Video Broadcasting- Satellite (DVB-S) system. By carefully integrating all of these rapidly deployable, interworking and collaborative networking technologies, we can fully exploit the joint benefits provided by WMNs, WSNs, balloon camera networks and DVB-S for real-time video streaming and image delivery in emergency situations among the disaster hit area, the remote control centre and the rescue teams in the field. The whole proposed system is implemented in a proven simulator. Through extensive simulations, the real-time visual communication performance of this integrated system has been numerically evaluated, towards a more in-depth understanding in supporting high-quality visual communications in such a demanding context.

We present a secure communication system constructed using pairs of nonlinear photonic physical unclonable functions (PUFs) that harness physical chaos in integrated silicon micro-cavities. Compared to a large, electronically stored one-time pad, our method provisions large amounts of information within the intrinsically complex nanostructure of the micro-cavities. By probing a micro-cavity with a rapid sequence of spectrally-encoded ultrafast optical pulses and measuring the lightwave responses, we experimentally demonstrate the ability to extract 2.4 Gb of key material from a single micro-cavity device. Subsequently, in a secure communication experiment with pairs of devices, we achieve bit error rates below 10 -5 at code rates of up to 0.1. The PUFs' responses are never transmitted over the channel or stored in digital memory, thus enhancing the security of the system. Additionally, the micro-cavity PUFs are extremely small, inexpensive, robust, and fully compatible with telecommunications infrastructure, components, and electronic fabrication. This approach can serve one-time pad or public key exchange applications where high security is required.

During an emerging health crisis like the 2014 Ebola outbreak in West Africa, communicating with communities to learn from them and to provide timely information can be a challenge. Insight into community thinking, however, is crucial for developing appropriate communication content and strategies and for monitoring the progress of the emergency response. In November 2014, the Health Communication Capacity Collaborative partnered with GeoPoll to implement a Short Message Service (SMS)-based survey that could create a link with affected communities and help guide the communication response to Ebola. The ideation metatheory of communication and behavior change guided the design of the survey questionnaire, which produced critical insights into trusted sources of information, knowledge of transmission modes, and perceived risks-all factors relevant to the design of an effective communication response that further catalyzed ongoing community actions. The use of GeoPoll's infrastructure for data collection proved a crucial source of almost-real-time data. It allowed for rapid data collection and processing under chaotic field conditions. Though not a replacement for standard survey methodologies, SMS surveys can provide quick answers within a larger research process to decide on immediate steps for communication strategies when the demand for speedy emergency response is high. They can also help frame additional research as the response evolves and overall monitor the pulse of the situation at any point in time.

National Aeronautics and Space Administration (NASA)'s Space Communication and Navigation Testbed on the International Space Station provides a unique opportunity to evaluate advanced communication techniques in an operational system. The experimental nature of the Testbed allows for rapid demonstrations while using flight hardware in a deployed system within NASA's networks. One example is variable coding and modulation, which is a method to increase data-throughput in a communication link. This paper describes recent flight testing with variable coding and modulation over S-band using a direct-to-earth link between the SCaN Testbed and the Glenn Research Center. The testing leverages the established Digital Video Broadcasting Second Generation (DVB-S2) standard to provide various modulation and coding options. The experiment was conducted in a challenging environment due to the multipath and shadowing caused by the International Space Station structure. Performance of the variable coding and modulation system is evaluated and compared to the capacity of the link, as well as standard NASA waveforms.

Reciprocal social behavior (RSB), an early-emerging capacity to engage in social contingency-which is foundational for both social learning and social competency-is hypothesized to be disrupted in autism spectrum disorder (ASD). The ability to quantify the full range of RSB during the toddler period, when core symptoms of ASD often arise, is pivotal for evaluating early risk for ASD, characterizing social development, and tracking response to early interventions. However, important parameters of variation in RSB-especially prior to the development of verbal language-can be nuanced and difficult to characterize using questionnaire-based methods. To address this challenge, we developed a system for measuring quantitative variation in RSB in toddlers (ages 18 - 30 months) that incorporated not only standard questionnaire data from caregivers but also a novel set of video-referenced items, through which a respondent compares the behavior of a subject to that observed in a short video of a young child manifesting a highly competent level of social communication. Testing of this measure in a general population sample of twins confirmed that both the video-referenced items and the RSB Total Score (video-referenced items plus non-video-referenced items) displayed unimodal, continuous distributions, strong internal consistency, marked preservation of individual differences, and extremely high heritability. In addition, video-referenced items were particularly sensitive to quantifying incremental changes in social communication, a major element of RSB, over the course of early childhood development. Scores on the vrRSB clearly differentiated children with and without ASD and these data comprise an initial validation of this promising method for quantifying early RSB-cross-sectionally, over time, and as a function of early intervention.

Communications interface for wireless communications headset

2004-01-01

A universal interface adapter circuit interfaces, for example, a wireless communications headset with any type of communications system, including those that require push-to-talk (PTT) signaling. The interface adapter is comprised of several main components, including an RF signaling receiver, a microcontroller and associated circuitry for decoding and processing the received signals, and programmable impedance matching and line interfacing circuitry for interfacing a wireless communications headset system base to a communications system. A signaling transmitter, which is preferably portable (e.g., handheld), is employed by the wireless headset user to send signals to the signaling receiver. In an embodiment of the invention directed specifically to push-to-talk (PTT) signaling, the wireless headset user presses a button on the signaling transmitter when they wish to speak. This sends a signal to the microcontroller which decodes the signal and recognizes the signal as being a PTT request. In response, the microcontroller generates a control signal that closes a switch to complete a voice connection between the headset system base and the communications system so that the user can communicate with the communications system. With this arrangement, the wireless headset can be interfaced to any communications system that requires PTT signaling, without modification of the headset device. In addition, the interface adapter can also be configured to respond to or deliver any other types of signals, such as dual-tone-multiple-frequency (DTMF) tones, and on/off hook signals. The present invention is also scalable, and permits multiple wireless users to operate independently in the same environment through use of a plurality of the interface adapters.

Communication networks in the brain: neurons, receptors, neurotransmitters, and alcohol.

PubMed

Lovinger, David M

2008-01-01

Nerve cells (i.e., neurons) communicate via a combination of electrical and chemical signals. Within the neuron, electrical signals driven by charged particles allow rapid conduction from one end of the cell to the other. Communication between neurons occurs at tiny gaps called synapses, where specialized parts of the two cells (i.e., the presynaptic and postsynaptic neurons) come within nanometers of one another to allow for chemical transmission. The presynaptic neuron releases a chemical (i.e., a neurotransmitter) that is received by the postsynaptic neuron's specialized proteins called neurotransmitter receptors. The neurotransmitter molecules bind to the receptor proteins and alter postsynaptic neuronal function. Two types of neurotransmitter receptors exist-ligand-gated ion channels, which permit rapid ion flow directly across the outer cell membrane, and G-protein-coupled receptors, which set into motion chemical signaling events within the cell. Hundreds of molecules are known to act as neurotransmitters in the brain. Neuronal development and function also are affected by peptides known as neurotrophins and by steroid hormones. This article reviews the chemical nature, neuronal actions, receptor subtypes, and therapeutic roles of several transmitters, neurotrophins, and hormones. It focuses on neurotransmitters with important roles in acute and chronic alcohol effects on the brain, such as those that contribute to intoxication, tolerance, dependence, and neurotoxicity, as well as maintained alcohol drinking and addiction.

Rapid Evolution of Sex Pheromone-Producing Enzyme Expression in Drosophila

Williams, Thomas M.; Carroll, Sean B.

2009-01-01

A wide range of organisms use sex pheromones to communicate with each other and to identify appropriate mating partners. While the evolution of chemical communication has been suggested to cause sexual isolation and speciation, the mechanisms that govern evolutionary transitions in sex pheromone production are poorly understood. Here, we decipher the molecular mechanisms underlying the rapid evolution in the expression of a gene involved in sex pheromone production in Drosophilid flies. Long-chain cuticular hydrocarbons (e.g., dienes) are produced female-specifically, notably via the activity of the desaturase DESAT-F, and are potent pheromones for male courtship behavior in Drosophila melanogaster. We show that across the genus Drosophila, the expression of this enzyme is correlated with long-chain diene production and has undergone an extraordinary number of evolutionary transitions, including six independent gene inactivations, three losses of expression without gene loss, and two transitions in sex-specificity. Furthermore, we show that evolutionary transitions from monomorphism to dimorphism (and its reversion) in desatF expression involved the gain (and the inactivation) of a binding-site for the sex-determination transcription factor, DOUBLESEX. In addition, we documented a surprising example of the gain of particular cis-regulatory motifs of the desatF locus via a set of small deletions. Together, our results suggest that frequent changes in the expression of pheromone-producing enzymes underlie evolutionary transitions in chemical communication, and reflect changing regimes of sexual selection, which may have contributed to speciation among Drosophila.

2018-01-01

Light emitting diodes - LEDs are modernizing the indoor illumination and replacing current incandescent and fluorescent lamps rapidly. LEDs have multiple advantages such as extremely high energy efficient, longer lifespan, and lower heat generation. Due to the ability to switch to different light intensity at a very fast rate, LED has given rise to a unique communication technology (visible light communication - VLC) used for high speed data transmission. By studying various kinds of commonly used VLC channel analysis: diffuse and line of sight channels, we presented a simply improved indoor and intra-vehicle visible light communication transmission model. Employing optical wireless communications within the vehicle, not only enhance user mobility, but also alleviate radio frequency interference, and increase efficiency by lowering the complexity of copper cabling. Moreover, a solution to eliminate ambient noise caused by environmental conditions is examined by using optical differential receiver. The simulation results show the improved received power distribution and signal to noise ratio - SNR.

The means of employee communication at the NASA Langley Research Center are reported, and their effectiveness evaluated. The history, purpose, and structure of the organization as well as the employee educational background and salary status are discussed. Some of the approaches used by Langley Research Center management in communicating with their men are addressed and compared with recommendations of experts in employee communication. The results of personal interviews involving both employee and management assessment of management-employee communication are presented and evaluated. Employees need a great deal more recommunication from management providing rationale behind the cancellation of existing projects or the disapproval of proposed research projects. Also NASA management needs to establish a policy and guidelines for the rapid and simultaneous dissemination of all non-restricted information to employees during organizational activities having potential adverse effects on large numbers of personnel. Finally some improvements should be made in employee orientation procedures.

Communicating geological hazards: assisting geoscientists in communication skills

NASA Astrophysics Data System (ADS)

Liverman, D. G. E.

2009-04-01

Communication is important in all aspects of the geosciences but is more prominent in the area of geological hazards, as the main audience for scientific information often lacks a geoscience background; and because the implications of not communicating results effectively can be very serious. Geoscientists working in the hazards area face particular challenges in communicating the concepts of risk, probability and uncertainty. Barriers to effective communication of geoscience include the complex language used by geoscientists, restriction of dissemination of results to traditional scientific media, identification of the target audience, inability to tailor products to a variety of audiences, and lack of institutional support for communication efforts. Geoscientists who work in the area of natural hazards need training in risk communication, media relations, and communicating to non-technical audiences. Institutions need to support the efforts of geoscientists in communicating their results through providing communications training; ensuring access to communications professionals; rewarding efforts to engage the public; and devoting sufficient staff and budget to the effort of disseminating results. Geoscientists themselves have to make efforts to change attitudes towards social science, and to become involved in decision making at a community level. The International Union of Geological Sciences Commission for "Geoscience for Environmental Management" established a working group to deal with these issues. This group is holding workshops, publishing collections of papers, and is looking at other means to aid geoscientists in addressing these problems.

NASA Astrophysics Data System (ADS)

Poliakon, J. A.

The current national defense doctrine calls for increased use of ground mobile strategic satellite communication earth terminals. This paper discusses some of the key communication terminal system issues and considerations associated with the design of nuclear hardened strategic ground mobile earth terminals. It considers system requirements such as nuclear hardness, rapid mobility, low profile, signal interference resistance, high availability, and long term independent operation. It also discusses impacts and implications associated with these requirements when imposed on a satellite earth terminal. It gives special focus to the ramifications of imposing mobility on earth terminals and its relationship to the system design approach used to arrive at an optimal system solution.

Rapid Acyl-Homoserine Lactone Quorum Signal Biodegradation in Diverse Soils†

PubMed Central

Wang, Ya-Juan; Leadbetter, Jared Renton

2005-01-01

Signal degradation impacts all communications. Although acyl-homoserine lactone (acyl-HSL) quorum-sensing signals are known to be degraded by defined laboratory cultures, little is known about their stability in nature. Here, we show that acyl-HSLs are biodegraded in soils sampled from diverse U.S. sites and by termite hindgut contents. When amended to samples at physiologically relevant concentrations, 14C-labeled acyl-HSLs were mineralized to 14CO2 rapidly and, at most sites examined, without lag. A lag-free turf soil activity was characterized in further detail. Heating or irradiation of the soil prior to the addition of radiolabel abolished mineralization, whereas protein synthesis inhibitors did not. Mineralization exhibited an apparent Km of 1.5 μM acyl-HSL, ca. 1,000-fold lower than that reported for a purified acyl-HSL lactonase. Under optimal conditions, acyl-HSL degradation proceeded at a rate of 13.4 nmol · h−1 · g of fresh weight soil−1. Bioassays established that the final extent of signal inactivation was greater than for its full conversion to CO2 but that the two processes were well coupled kinetically. A most probable number of 4.6 × 105 cells · g of turf soil−1 degraded physiologically relevant amounts of hexanoyl-[1-14C]HSL to 14CO2. It would take chemical lactonolysis months to match the level of signal decay achieved in days by the observed biological activity. Rapid decay might serve either to quiet signal cross talk that might otherwise occur between spatially separated microbial aggregates or as a full system reset. Depending on the context, biological signal decay might either promote or complicate cellular communications and the accuracy of population density-based controls on gene expression in species-rich ecosystems.

RAPID COMMUNICATION: Improving prediction accuracy of GPS satellite clocks with periodic variation behaviour

NASA Astrophysics Data System (ADS)

Heo, Youn Jeong; Cho, Jeongho; Heo, Moon Beom

2010-07-01

The broadcast ephemeris and IGS ultra-rapid predicted (IGU-P) products are primarily available for use in real-time GPS applications. The IGU orbit precision has been remarkably improved since late 2007, but its clock products have not shown acceptably high-quality prediction performance. One reason for this fact is that satellite atomic clocks in space can be easily influenced by various factors such as temperature and environment and this leads to complicated aspects like periodic variations, which are not sufficiently described by conventional models. A more reliable prediction model is thus proposed in this paper in order to be utilized particularly in describing the periodic variation behaviour satisfactorily. The proposed prediction model for satellite clocks adds cyclic terms to overcome the periodic effects and adopts delay coordinate embedding, which offers the possibility of accessing linear or nonlinear coupling characteristics like satellite behaviour. The simulation results have shown that the proposed prediction model outperforms the IGU-P solutions at least on a daily basis.

To describe a new technique for fabricating an 3D resin model by 3D reconstruction and rapid prototyping, and to analyze the precision of this method. An optical grating scanner was used to acquire the data of silastic cavity block , digital dental cast was reconstructed with the data through Geomagic Studio image processing software. The final 3D reconstruction was saved in the pattern of Stl. The 3D resin model was fabricated by fuse deposition modeling, and was compared with the digital model and gypsum model. The data of three groups were statistically analyzed using SPSS 16.0 software package. No significant difference was found in gypsum model,digital dental cast and 3D resin model (P>0.05). Rapid prototyping manufacturing and digital modeling would be helpful for dental information acquisition, treatment design, appliance manufacturing, and can improve the communications between patients and doctors.

Examining the communication skills of a young cochlear implant pioneer.

2006-01-01

The purpose of this longitudinal case study was to closely examine one deaf child's experience with a cochlear implant and his speech, language, and communication skills from kindergarten through middle and high school using both developmental and sociocultural frameworks. The target child was one of the first children to receive a cochlear implant in the United States in 1988, when he was 5 years of age. The developmental analysis revealed that prior to receiving a cochlear implant the child demonstrated profound delays in speech and language skill development. His speech and language skills grew slowly during the first 3-4 years following implantation, very rapidly from about 5 through 7 years postimplantation, then slowed to rates that were highly similar to same-age peers with normal hearing. The sociocultural analysis revealed that the child's communicative competence improved; that he used sign language but use of sign language decreased as his oral communication skills improved; that as his oral communication skills improved, the adults talked and directed the topic of conversation less frequently; and that topics became less concrete and more personal over time. The results of this study indicate that we may learn more about how to support children who use cochlear implants by examining what they are saying as well as how they are saying it.

Optical wireless communications: Theory and applications

NASA Astrophysics Data System (ADS)

Aminikashani, Mohammadreza

on the potentials of currently used FSO systems. Furthermore, utilizing this new statistical channel model, closed-form expressions for the diversity gain and the error rate performance of FSO links with spatial diversity are derived. In addition to addressing ways to improve outdoor FSO communication sys- tems, this dissertation addresses some major challenges in indoor visible light communication (VLC). VLC is an advantageous technique that is proposed for wireless indoor communications. In VLC systems, the existence of multiple paths between the transmitter and receiver causes multipath distortion, particularly in links using non-directional transmitters and receivers, or in links relying upon non-line of-sight propagation. This multipath distortion can lead to intersymbol interference (ISI) at high bit rates. Multicarrier modulation usually implemented by orthogonal frequency division multiplexing (OFDM) can be used to mitigate ISI and multipath dispersion. Nevertheless, the performance of VLC systems employing OFDM modulation is significantly affected by nonlinear characteristic of light-emitting diode (LED) due to the large peak-to-average power ratio (PAPR) of OFDM signal. In other words, signal amplitudes below the LED turn-on-voltage and above the LED saturation point are clipped. This dissertation targets these important issues and successfully addresses them by developing some techniques to reduce high PAPR of optical OFDM signal and determining the optimum operating characteristics of LEDs for combined lighting and communications applications. VLC can also provide a practical solution for indoor positioning as global po- sitioning system (GPS) does not provide an accurate and rapid indoor positioning since GPS radio signals are attenuated and scattered by walls of large buildings and other objects. A practical VLC system would be likely to deploy the same configuration for both positioning and communication purposes where high speed data rates are desired

Non-Mechanical Beam Steering in Free-Space Optical Communication Transceivers

NASA Astrophysics Data System (ADS)

Shortt, Kevin

Free-space optical communications systems are a rapidly growing field as they carry many of the advantages of traditional fibre-based communications systems without the added investment of installing complex infrastructure. Moreover, these systems are finding key niches in mobile platforms in order to take advantage of the increased bandwidth over traditional RF systems. Of course, the inevitable problem of tracking arises when dealing with mobile stations. To compound the problem in the case of communications to low Earth or geosynchronous orbits, FSOC systems typically operate with tightly confined beams over great distances often requiring pointing accuracies on the order of micro-radians or smaller. Mechanisms such as gimbal mounts and fine-steering mirrors are the usual candidates for platform stabilization, however, these clearly have substantial power requirements and inflate the mass of the system. Spatial light modulators (also known as optical phased arrays), on the other hand, offer a suitable alternative for beam-pointing stabilization. Some of the advantages of spatial light modulators over fine-steering mirrors include programmable multiple simultaneous beams, dynamic focus/defocus and moderate to excellent optical power handling capability. This thesis serves as an investigation into the implementation of spatial light modulators as a replacement for traditional fine-steering mirrors in the fine-pointing subsystem. In particular, pointing accuracy and scanning ability will be highlighted as performance metrics in the context of a variety of communication scenarios. Keywords: Free-space optical communications, beam steering, fine-steering mirror, spatial light modulator, optical phased array.

Data communication through multiple physical media: applications to munitions

NASA Astrophysics Data System (ADS)

Dhadwal, Harbans S.; Rastegar, Jahangir; Feng, Dake; Kwok, Philip

2015-05-01

Electronic systems comprising of subassemblies, distributed across different physical media, require seamless communication between processors and sensors embedded in the disparate volumes. For example, smart munitions systems embed sensors and other key control electronics, throughout the structure, in vastly different physical media. In addition to the obvious space constraints, these structures are subjected to high G forces during launch. Thus, communications through wire harnesses becomes cumbersome, make assembly process and testing difficult, and challenging to make survive high G firing. Here we focus on an approach that takes advantage of the partial optical transparency of epoxy material commonly used in potting electronic components in munitions, as well as the wave guiding that is possible through the body of the munitions wall which is made from composite materials. Experimental results show that a wireless optical link, connecting various parts of the distributed system, is possible at near IR frequencies. Data can be rapidly parsed between a processor, sensors and actuators. We present experimental data for a commercial epoxy system, which is used to embed a number of IrDA devices inside the cone of 120 mm mortar shell. IrDA devices using the FIR data rates establish point-to-point communication through various media, representative of the environment inside the 120 mm mortar cone.

Thinking about a reader's mind: fostering communicative clarity in the compositions of youth with autism spectrum disorders.

A critical component of effective communication is the ability to consider the knowledge state of one's audience, yet individuals with autism spectrum disorders (ASD) have difficulty representing the mental states of others. In the present study, youth with high-functioning ASD were trained to consider their reader's knowledge states in their compositions using a novel computer-based task. After two training trials, participants who received visual feedback from a confederate demonstrated significantly greater communicative clarity on the training measure compared to a control group. The improvements from training transferred to similar and very different tasks, and were maintained approximately 6 weeks post-intervention. These results provide support for the sustained efficacy of a rapid and motivating communication intervention for youth with high-functioning ASD.

Patients in the completely locked-in state have no means of communication and they represent the target population for brain-computer interface research in the last 15 years. Although different paradigms have been tested and different physiological signals used, to date no sufficiently documented completely locked-in state patient was able to control a brain-computer interface over an extended time period. We introduce Pavlovian semantic conditioning to enable basic communication in completely locked-in state. This novel paradigm is based on semantic conditioning for online classification of neuroelectric or any other physiological signals to discriminate between covert (cognitive) 'yes' and 'no' responses. The paradigm comprised the presentation of affirmative and negative statements used as conditioned stimuli, while the unconditioned stimulus consisted of electrical stimulation of the skin paired with affirmative statements. Three patients with advanced amyotrophic lateral sclerosis participated over an extended time period, one of which was in a completely locked-in state, the other two in the locked-in state. The patients' level of vigilance was assessed through auditory oddball procedures to study the correlation between vigilance level and the classifier's performance. The average online classification accuracies of slow cortical components of electroencephalographic signals were around chance level for all the patients. The use of a non-linear classifier in the offline classification procedure resulted in a substantial improvement of the accuracy in one locked-in state patient achieving 70% correct classification. A reliable level of performance in the completely locked-in state patient was not achieved uniformly throughout the 37 sessions despite intact cognitive processing capacity, but in some sessions communication accuracies up to 70% were achieved. Paradigm modifications are proposed. Rapid drop of vigilance was detected suggesting attentional

Cellulose is the most abundant natural polysaccharide polymer, which is used as such or its derivatives in a number of advanced applications, such as in paper, packaging, biosorption, and biomedical. In present communication, in an effort to develop a proficient way to rapidly synthesize poly(methyl acrylate)-graft-cellulose (PMA-g-cellulose) copolymers, rapid graft copolymerization synthesis was carried out under microwave conditions using ferrous ammonium sulfate-potassium per sulfate (FAS-KPS) as redox initiator. Different reaction parameters such as microwave radiation power, ratio of monomer, solvent and initiator concentrations were optimized to get the highest percentage of grafting. Grafting percentage was found to increase with increase in microwave power up to 70%, and maximum 36.73% grafting was obtained after optimization of all parameters. Fourier transforms infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA/DTA/DTG) analysis were used to confirm the graft copolymerization of poly(methyl acrylate) (PMA) onto the mercerized cellulose. The grafted cellulosic polymers were subsequently subjected to the evaluation of different physico-chemical properties in order to access their application in everyday life, in a direction toward green environment. The grafted copolymers demonstrated increased chemical resistance, and higher thermal stability. Published by Elsevier Ltd.

Rapid response systems are commonly employed by hospitals to identify and respond to deteriorating patients outside of the intensive care unit. Controversy exists about the benefits of rapid response systems. We aimed to review the current state of the rapid response literature, including evolving aspects of afferent (risk detection) and efferent (intervention) arms, outcome measurement, process improvement, and implementation. Articles written in English and published in PubMed. Rapid response systems are heterogeneous, with important differences among afferent and efferent arms. Clinically meaningful outcomes may include unexpected mortality, in-hospital cardiac arrest, length of stay, cost, and processes of care at end of life. Both positive and negative interventional studies have been published, although the two largest randomized trials involving rapid response systems - the Medical Early Response and Intervention Trial (MERIT) and the Effect of a Pediatric Early Warning System on All-Cause Mortality in Hospitalized Pediatric Patients (EPOCH) trial - did not find a mortality benefit with these systems, albeit with important limitations. Advances in monitoring technologies, risk assessment strategies, and behavioral ergonomics may offer opportunities for improvement. Rapid responses may improve some meaningful outcomes, although these findings remain controversial. These systems may also improve care for patients at the end of life. Rapid response systems are expected to continue evolving with novel developments in monitoring technologies, risk prediction informatics, and work in human factors. Copyright © 2018 Elsevier B.V.

Impact of unseen assumptions on communication of atmospheric carbon mitigation options

2010-12-01

With the rapid access and dissemination of information made available through online and digital pathways, there is need for a concurrent openness and transparency in communication of scientific investigation. Even with open communication it is essential that the scientific community continue to provide impartial result-driven information. An unknown factor in climate literacy is the influence of an impartial presentation of scientific investigation that has utilized biased base-assumptions. A formal publication appendix, and additional digital material, provides active investigators a suitable framework and ancillary material to make informed statements weighted by assumptions made in a study. However, informal media and rapid communiqués rarely make such investigatory attempts, often citing headline or key phrasing within a written work. This presentation is focused on Geologic Carbon Sequestration (GCS) as a proxy for the wider field of climate science communication, wherein we primarily investigate recent publications in GCS literature that produce scenario outcomes using apparently biased pro- or con- assumptions. A general review of scenario economics, capture process efficacy and specific examination of sequestration site assumptions and processes, reveals an apparent misrepresentation of what we consider to be a base-case GCS system. The authors demonstrate the influence of the apparent bias in primary assumptions on results from commonly referenced subsurface hydrology models. By use of moderate semi-analytical model simplification and Monte Carlo analysis of outcomes, we can establish the likely reality of any GCS scenario within a pragmatic middle ground. Secondarily, we review the development of publically available web-based computational tools and recent workshops where we presented interactive educational opportunities for public and institutional participants, with the goal of base-assumption awareness playing a central role.

1995-01-01

To design a demodulator applicable to mobile satellite communication systems using differential phase shift keying modulation, we have developed key technologies including an anti-Rician-fading demodulation scheme, an initial acquisition scheme, automatic gain control (AGC), automatic frequency control (AFC), and bit timing recovery (BTR). Using these technologies, we have developed one-chip digital signal processor (DSP) modem for mobile terminal, which is compact, of light weight, and of low power consumption. Results of performance test show that the developed DSP modem achieves good performance in terms of bit error ratio in mobile satellite communication environment, i.e., Rician fading channel. It is also shown that the initial acquisition scheme acquires received signal rapidly even if the carrier-to-noise power ratio (CNR) of the received signal is considerably low.

Early Earth differentiation [rapid communication

NASA Astrophysics Data System (ADS)

Walter, Michael J.; Trønnes, Reidar G.

2004-09-01

The birth and infancy of Earth was a time of profound differentiation involving massive internal reorganization into core, mantle and proto-crust, all within a few hundred million years of solar system formation ( t0). Physical and isotopic evidence indicate that the formation of iron-rich cores generally occurred very early in planetesimals, the building blocks of proto-Earth, within about 3 million years of t0. The final stages of terrestrial planetary accretion involved violent and tremendously energetic giant impacts among core-segregated Mercury- to Mars-sized objects and planetary embryos. As a consequence of impact heating, the early Earth was at times partially or wholly molten, increasing the likelihood for high-pressure and high-temperature equilibration among core- and mantle-forming materials. The Earth's silicate mantle harmoniously possesses abundance levels of the siderophile elements Ni and Co that can be reconciled by equilibration between iron alloy and silicate at conditions comparable to those expected for a deep magma ocean. Solidification of a deep magma ocean possibly involved crystal-melt segregation at high pressures, but subsequent convective stirring of the mantle could have largely erased nascent layering. However, primitive upper mantle rocks apparently have some nonchondritic major and trace element refractory lithophile element ratios that can be plausibly linked to early mantle differentiation of ultra-high-pressure mantle phases. The geochemical effects of crystal fractionation in a deep magma ocean are partly constrained by high-pressure experimentation. Comparison between compositional models for the primitive convecting mantle and bulk silicate Earth generally allows, and possibly favors, 10-15% total fractionation of a deep mantle assemblage comprised predominantly of Mg-perovskite and with minor but geochemically important amounts of Ca-perovskite and ferropericlase. Long-term isolation of such a crystal pile is generally consistent with isotopic constraints for time-integrated Sm/Nd and Lu/Hf ratios in the modern upper mantle and might account for the characteristics of some mantle isotope reservoirs. Although much remains to be learned about the earliest formative period in the Earth's development, a convergence of theoretical, physical, isotopic and geochemical arguments is beginning to yield a self-consistent portrait of the infant Earth.

How do auditory cortex neurons represent communication sounds?

PubMed

Gaucher, Quentin; Huetz, Chloé; Gourévitch, Boris; Laudanski, Jonathan; Occelli, Florian; Edeline, Jean-Marc

2013-11-01

A major goal in auditory neuroscience is to characterize how communication sounds are represented at the cortical level. The present review aims at investigating the role of auditory cortex in the processing of speech, bird songs and other vocalizations, which all are spectrally and temporally highly structured sounds. Whereas earlier studies have simply looked for neurons exhibiting higher firing rates to particular conspecific vocalizations over their modified, artificially synthesized versions, more recent studies determined the coding capacity of temporal spike patterns, which are prominent in primary and non-primary areas (and also in non-auditory cortical areas). In several cases, this information seems to be correlated with the behavioral performance of human or animal subjects, suggesting that spike-timing based coding strategies might set the foundations of our perceptive abilities. Also, it is now clear that the responses of auditory cortex neurons are highly nonlinear and that their responses to natural stimuli cannot be predicted from their responses to artificial stimuli such as moving ripples and broadband noises. Since auditory cortex neurons cannot follow rapid fluctuations of the vocalizations envelope, they only respond at specific time points during communication sounds, which can serve as temporal markers for integrating the temporal and spectral processing taking place at subcortical relays. Thus, the temporal sparse code of auditory cortex neurons can be considered as a first step for generating high level representations of communication sounds independent of the acoustic characteristic of these sounds.

Charriere, M. K. M.; Bogaard, T.; Mostert, E.

2014-12-01

Among all the natural hazards, snow avalanches are the only ones for which a public danger scale is globally used. It consists of 5 levels of danger displayed with a given number and colour and for each of them, behavioural advices are provided. Even though this is standardized in most of the countries affected by this natural hazard, the tools (usually websites or smartphone applications) with which the information is disseminated to the general pubic differs, particularly in terms of target audience and level of details. This study aims at gathering the perspectives of several communicators that are responsible for these communication practices. The survey was created to assess how and why choices were made in the design process of the communication tools and to determine how their effectiveness is evaluated. Along with a review of existing avalanche risk communication tools, this study provides guidelines for communication and the evaluation of its effectiveness.

While critical value procedures have been adopted in most areas of the clinical laboratory, their use in transfusion medicine has not been reviewed in detail. The results of this study present a comprehensive overview of critical value reporting and communication practices in transfusion medicine in the United States. A web-based survey was developed to collect data on the prevalence of critical value procedures and practices of communicating results. The survey was distributed via email to US hospital-based blood banks. Of 123 facilities surveyed, 84 (68.3%) blood banks had a critical value procedure. From a panel of 23 common blood bank results, nine results were selected by more than 70% of facilities as either a critical value or requiring rapid communication as defined by an alternate procedure. There was overlap among results communicated by facilities with and without a critical value procedure. The most frequently communicated results, such as incompatible crossmatch for RBC units issued uncrossmatched, delay in finding compatible blood due to a clinically significant antibody, and transfusion reaction evaluation suggestive of a serious adverse event, addressed scenarios associated with the leading reported causes of transfusion-related fatalities.

Delivering effective science communication: advice from a professional science communicator.

PubMed

Illingworth, Sam

2017-10-01

Science communication is becoming ever more prevalent, with more and more scientists expected to not only communicate their research to a wider public, but to do so in an innovative and engaging manner. Given the other commitments that researchers and academics are required to fulfil as part of their workload models, it is unfair to be expect them to also instantly produce effective science communication events and activities. However, by thinking carefully about what it is that needs to be communicated, and why this is being done, it is possible to develop high-quality activities that are of benefit to both the audience and the communicator(s). In this paper, I present some practical advice for developing, delivering and evaluating effective science communication initiatives, based on over a decade of experience as being a professional science communicator. I provide advice regarding event logistics, suggestions on how to successfully market and advertise your science communication initiatives, and recommendations for establishing effective branding and legacy.

A cross-domain communication resource scheduling method for grid-enabled communication networks

NASA Astrophysics Data System (ADS)

Zheng, Xiangquan; Wen, Xiang; Zhang, Yongding

2011-10-01

To support a wide range of different grid applications in environments where various heterogeneous communication networks coexist, it is important to enable advanced capabilities in on-demand and dynamical integration and efficient co-share with cross-domain heterogeneous communication resource, thus providing communication services which are impossible for single communication resource to afford. Based on plug-and-play co-share and soft integration with communication resource, Grid-enabled communication network is flexibly built up to provide on-demand communication services for gird applications with various requirements on quality of service. Based on the analysis of joint job and communication resource scheduling in grid-enabled communication networks (GECN), this paper presents a cross multi-domain communication resource cooperatively scheduling method and describes the main processes such as traffic requirement resolution for communication services, cross multi-domain negotiation on communication resource, on-demand communication resource scheduling, and so on. The presented method is to afford communication service capability to cross-domain traffic delivery in GECNs. Further research work towards validation and implement of the presented method is pointed out at last.

RAPID and DDS

NASA Technical Reports Server (NTRS)

Utz, Hans Heinrich

2011-01-01

This talk gives an overview of the the Robot Applications Programmers Interface Delegate (RAPID) as well as the distributed systems middleware Data Distribution Service (DDS). DDS is an open software standard, RAPID is cleared for open-source release under NOSA. RAPID specifies data-structures and semantics for high-level telemetry published by NASA robotic software. These data-structures are supported by multiple robotic platforms at Johnson Space Center (JSC), Jet Propulsion Laboratory (JPL) and Ames Research Center (ARC), providing high-level interoperability between those platforms. DDS is used as the middleware for data transfer. The feature set of the middleware heavily influences the design decision made in the RAPID specification. So it is appropriate to discuss both in this introductory talk.

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

NASA Astrophysics Data System (ADS)

Li, Haiqing; Chatterjee, Samir

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

Blue-light digital communication in underwater environments utilizing orbital angular momentum

Baghdady, Joshua; Miller, Keith; Osler, Sean; Morgan, Kaitlyn; Li, Wenzhe; Johnson, Eric; Cochenour, Brandon

2016-05-01

Underwater optical communication has recently become the topic of much investigation as the demands for underwater data transmission have rapidly grown in recent years. The need for reliable, high-speed, secure underwater communication has turned increasingly to blue-light optical solutions. The blue-green visible wavelength window provides an attractive solution to the problem of underwater data transmission thanks to its low attenuation, where traditional RF solutions used in free-space communications collapse. Beginning with GaN laser diodes as the optical source, this work explores the encoding and transmission of digital data across underwater environments of varying turbidities. Given the challenges present in an underwater environment, such as the mechanical and optical turbulences that make proper alignment difficult to maintain, it is desirable to achieve extremely high data rates in order to allow the time window of alignment between the transmitter and receiver to be as small as possible. In this paper, work is done to increase underwater data rates through the use of orbital angular momentum. Results are shown for a range of data rates across a variety of channel types ranging in turbidity from that of a clear ocean to a dirty harbor.

Volatile communication in plant-aphid interactions.

PubMed

de Vos, Martin; Jander, Georg

2010-08-01

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

Japanese life expectancy increased by about 13.7 years during the first decade after World War II, despite the country's post-war poverty. Although it is known that medical progress explains part of this increase, roles of non-medical factors have not been systematically studied. This study hypothesizes that non-medical factors, in addition to medical factors, are associated with the rapid increase in life expectancy in Japan. We analyzed the time trends of potential explanatory factors and used regression analysis with historical data from the Ministry of Internal Affairs and Communications' Historical Statistics of Japan during the period between 1946 and 1983. Time trends analysis revealed that the rapid increase in life expectancy preceded the dramatic growth of per capita Gross Domestic Product (GDP) by 10 years. In education, the nearly universal enrollment in elementary schools and increased advancement to upper secondary schools for both sexes were associated with better health. Regarding legislation, 32 health laws were passed in the first decade after the war and these laws were associated with improved health. Using regression analysis, we found that the enrollment rate in elementary schools, the number of health laws, and expansion of community-based activity staff were significantly associated with the increased life expectancy during the first decade after World War II. To conclude, in addition to medical factors, non-medical factors applied across the country, particularly education, community-based activities and legislation were associated with the rapid increase in Japanese life expectancy after World War II.

Atypical rapid audio-visual temporal recalibration in autism spectrum disorders.

Changes in sensory and multisensory function are increasingly recognized as a common phenotypic characteristic of Autism Spectrum Disorders (ASD). Furthermore, much recent evidence suggests that sensory disturbances likely play an important role in contributing to social communication weaknesses-one of the core diagnostic features of ASD. An established sensory disturbance observed in ASD is reduced audiovisual temporal acuity. In the current study, we substantially extend these explorations of multisensory temporal function within the framework that an inability to rapidly recalibrate to changes in audiovisual temporal relations may play an important and under-recognized role in ASD. In the paradigm, we present ASD and typically developing (TD) children and adolescents with asynchronous audiovisual stimuli of varying levels of complexity and ask them to perform a simultaneity judgment (SJ). In the critical analysis, we test audiovisual temporal processing on trial t as a condition of trial t - 1. The results demonstrate that individuals with ASD fail to rapidly recalibrate to audiovisual asynchronies in an equivalent manner to their TD counterparts for simple and non-linguistic stimuli (i.e., flashes and beeps, hand-held tools), but exhibit comparable rapid recalibration for speech stimuli. These results are discussed in terms of prior work showing a speech-specific deficit in audiovisual temporal function in ASD, and in light of current theories of autism focusing on sensory noise and stability of perceptual representations.

The communication is an action that occupies a lot of part of the life of every individual and understands a whole activity that the purpose has to reach a preset goal: the communication obligatorily foresees the presence of a recipient/receiving.During communication we used both the word, but also the gesture and the way of do/say. The oral communication represents the most complete system however, evolved, end and thin to communicate, able to also express concepts and thoughts and not only behaviors: with it he can also lie and to supply misinformation. The oral communication also possesses an important temporal value, in how much you/he/she can define him now, the before and the then, but also the ability to determine the human relationships, because it participates in to define the different roles in which broadcasting station and receiver are found at that time. The truest power of the words is that to create, to maintain, to modify other people's behaviors; a natural correlation exists that is between communication and behavior. The final objective of the communication results therefore that to create or to modify the relationships and the human behaviors; in other terms we can be affirmed that the words can determine the reality. The true ragion to be to communicate is the purpose however, that who speaks he/she wants to reach: it is a voluntary, both mental and physical effort, that originates from a need both explicit and implicit of whom sends forth the message.

Leading US nano-scientists' perceptions about media coverage and the public communication of scientific research findings

Corley, Elizabeth A.; Kim, Youngjae; Scheufele, Dietram A.

2011-12-01

Despite the significant increase in the use of nanotechnology in academic research and commercial products over the past decade, there have been few studies that have explored scientists' perceptions and attitudes about the technology. In this article, we use survey data from the leading U.S. nano-scientists to explore their perceptions about two issues: the public communication of research findings and media coverage of nanotechnology, which serves as one relatively rapid outlet for public communication. We find that leading U.S. nano-scientists do see an important connection between the public communication of research findings and public attitudes about science. Also, there is a connection between the scientists' perceptions about media coverage and their views on the timing of public communication; scientists with positive attitudes about the media are more likely to support immediate public communication of research findings, while others believe that communication should take place only after research findings have been published through a peer-review process. We also demonstrate that journalists might have a more challenging time getting scientists to talk with them about nanotechnology news stories because nano-scientists tend to view media coverage of nanotechnology as less credible and less accurate than general science media coverage. We conclude that leading U.S. nano-scientists do feel a sense of responsibility for communicating their research findings to the public, but attitudes about the timing and the pathway of that communication vary across the group.

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

PubMed

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.

What whiteboards in a trauma center operating suite can teach us about emergency department communication.

2007-10-01

Highly reliable, efficient collaborative work relies on excellent communication. We seek to understand how a traditional whiteboard is used as a versatile information artifact to support communication in rapid-paced, highly dynamic collaborative work. The similar communicative demands of the trauma operating suite and an emergency department (ED) make the findings applicable to both settings. We took photographs and observed staff's interaction with a whiteboard in a 6-bed surgical suite dedicated to trauma service. We analyzed the integral role of artifacts in cognitive activities as when workers configure and manage visual spaces to simplify their cognitive tasks. We further identified characteristics of the whiteboard as a communicative information artifact in supporting coordination in fast-paced environments. We identified 8 ways in which the whiteboard was used by physicians, nurses, and with other personnel to support collaborative work: task management, team attention management, task status tracking, task articulation, resource planning and tracking, synchronous and asynchronous communication, multidisciplinary problem solving and negotiation, and socialization and team building. The whiteboard was highly communicative because of its location and installation method, high interactivity and usability, high expressiveness, and ability to visualize transition points to support work handoffs. Traditional information artifacts such as whiteboards play significant roles in supporting collaborative work. How these artifacts are used provides insights into complicated information needs of teamwork in highly dynamic, high-risk settings such as an ED.

In the photo at bottom right, a U.S. Park Police officer is demonstrating a battery-powered communications system, sufficiently compact to be packed in a briefcase-size container, which can send and receive signals over great distances by means of satellite relay. Key to the system's efficacy is the high-powered transmitting and receiving equipment aboard such NASA satellites as the Applications Technology Satellite6 (ATS-6) and the joint U.S.-Canadian Communications Technology Satellite (CTS); this enables the briefcase communicator to pick up satellite-relayed signals by means of the small hook-on antenna shown instead of the more elaborate-ground equipment customarily needed. Developed by NASA's Goddard Space Flight Center, the communicator is intended for use in emergency situations. It has utility, for example, in disasters, such as floods and hurricanes, where power failure disrupts conventional communications; for on-the-spot transmissions from major accident sites; or in remote areas where no other means of communication exists

Organizational structure and communication networks in a university environment

The “six degrees of separation” between any two individuals on Earth has become emblematic of the “small world” theme, even though the information conveyed via a chain of human encounters decays very rapidly with increasing chain length, and diffusion of information via this process may be very inefficient in large human organizations. The information flow on a communication network in a large organization, the University of Oslo, has been studied by analyzing email records. The records allow for quantification of communication intensity across organizational levels and between organizational units (referred to as “modules”). We find that the number of email messages within modules scales with module size to the power of 1.29±.06 , and the frequency of communication between individuals decays exponentially with the number of links required upward in the organizational hierarchy before they are connected. Our data also indicates that the number of messages sent by administrative units is proportional to the number of individuals at lower levels in the administrative hierarchy, and the “divergence of information” within modules is associated with this linear relationship. The observed scaling is consistent with a hierarchical system in which individuals far apart in the organization interact little with each other and receive a disproportionate number of messages from higher levels in the administrative hierarchy.

Non-electronic communication aids for people with complex communication needs.

PubMed

Iacono, Teresa; Lyon, Katie; West, Denise

2011-10-01

Non-electronic communication aids provide one form of augmentative and alternative communication (AAC) for people with complex communication needs. The aim here was to explore non-electronic communication aids as one AAC option and research challenges. This aim was addressed by reviewing funding for the provision of AAC systems, data from an Australian pilot project providing non-electronic communication aids, an audit of aided AAC published studies (2000-2009), and discussion of the review literature. Combined, these sources indicate that although there is great demand for non-electronic communication aids, funding schemes, both in Australia and internationally, have focused on electronic communication aids. Such funding has usually failed to meet the total device costs and has not provided for adequate speech-language pathology support. Data from the pilot indicated the demand for non-electronic communication aids, and patterns suggest potential factors that govern the types selected. Despite the high demand for non-electronic aids, the research literature has tended to focus on electronic communication aids, including within intervention studies and addressing design features and long-term outcomes. Concerns about ensuring that AAC systems are chosen according to the assessed needs of individuals are discussed within the context of limitations in outcomes research and appropriate outcome measures.

Multimedia Astronomy Communication: Effectively Communicate Astronomy to the Desired Audience

NASA Astrophysics Data System (ADS)

Star Cartier, Kimberly Michelle; Wright, Jason

2017-01-01

A fundamental aspect of our jobs as scientists is communicating our work to others. In this, the field of astronomy holds the double-edged sword of ubiquitous fascination: the topic has been of interest to nearly the entire global population at some point in their lives, yet the learning curve is steep within any subfield and rife with difficult-to-synthesize details. Compounding this issue is the ever-expanding array of methods to reach people in today's Communications Era. Each communication medium has its own strengths and weaknesses, is appropriate in different situations, and requires its own specific skillset in order to maximize its functionality. Despite this, little attention is given to training astronomers in effective communication techniques, often relying on newcomers to simply pick up the ability by mimicking others and assuming that a firm grasp on the subject matter will make up for deficiencies in communication theory. This can restrict astronomers to a narrow set of communication methods, harming both the communicators and the audience who may struggle to access the information through those media.Whether writing a research paper to academic peers or giving an astronomy talk to a pubic audience, successfully communicating a scientific message requires more than just an expert grasp on the topic. A communicator must understand the makeup and prior knowledge of the desired audience, be able to break down the salient points of the topic into pieces that audience can digest, select and maximize upon a medium to deliver the message, and frame the message in a way that hooks the audience and compels further interest. In this work we synthesize the requirements of effective astronomy communication into a few key questions that every communicator needs to answer. We then discuss some of the most common media currently used to communicate astronomy, give both effective and poor examples of utilizing these media to communicate astronomy, and provide key

When designing systems for elderly drivers, it has been shown that: (1) simplifying a task reduces performance differences between old and young; and (2) the optimization of onboard systems (better legibility and intelligibility of the information, simplified dialogue) in relation to the abilities of elderly drivers benefits the rest of the user population. Elderly people do not automatically reject new information and assistance technologies especially when the systems are user friendly. However, the ergonomics of these new technologies must be studied, with particular attention to the specific needs of the elderly, in order not to marginalize them PMID:12460953

Effective communication at the point of multiple sclerosis diagnosis.

PubMed

Solari, Alessandra

2014-04-01

As a consequence of the current shortened diagnostic workup, people with multiple sclerosis (PwMS) are rapidly confronted with a disease of uncertain prognosis that requires complex treatment decisions. This paper reviews studies that have assessed the experiences of PwMS in the peri-diagnostic period and have evaluated the efficacy of interventions providing information at this critical moment. The studies found that the emotional burden on PwMS at diagnosis was high, and emphasised the need for careful monitoring and management of mood symptoms (chiefly anxiety). Information provision did not affect anxiety symptoms but improved patients' knowledge of their condition, the achievement of 'informed choice', and satisfaction with the diagnosis communication. It is vital to develop and implement information and decision aids for PwMS, but this is resource intensive, and international collaboration may be a way forward. The use of patient self-assessed outcome measures that appraise the quality of diagnosis communication is also important to allow health services to understand and meet the needs and preferences of PwMS.

Ultraviolet absorbing compounds provide a rapid response mechanism for UV protection in some reef fish.

Braun, C; Reef, R; Siebeck, U E

2016-07-01

The external mucus surface of reef fish contains ultraviolet absorbing compounds (UVAC), most prominently Mycosporine-like Amino Acids (MAAs). MAAs in the external mucus of reef fish are thought to act as sunscreens by preventing the damaging effects of ultraviolet radiation (UVR), however, direct evidence for their protective role has been missing. We tested the protective function of UVAC's by exposing fish with naturally low, Pomacentrus amboinensis, and high, Thalassoma lunare, mucus absorption properties to a high dose of UVR (UVB: 13.4W∗m(-2), UVA: 6.1W∗m(-2)) and measuring the resulting DNA damage in the form of cyclobutane pyrimidine dimers (CPDs). For both species, the amount of UV induced DNA damage sustained following the exposure to a 1h pulse of high UVR was negatively correlated with mucus absorbance, a proxy for MAA concentration. Furthermore, a rapid and significant increase in UVAC concentration was observed in P. amboinensis following UV exposure, directly after capture and after ten days in captivity. No such increase was observed in T. lunare, which maintained relatively high levels of UV absorbance at all times. P. amboinensis, in contrast to T. lunare, uses UV communication and thus must maintain UV transparent mucus to be able to display its UV patterns. The ability to rapidly alter the transparency of mucus could be an important adaptation in the trade off between protection from harmful UVR and UV communication. Copyright © 2016 Elsevier B.V.

2012-08-28

The digital revolution will have a profound impact on how physicians and health care delivery organizations interact with patients and the community at-large. Over the coming decades, face-to-face patient/doctor contacts will become less common and exchanges between consumers and providers will increasingly be mediated by electronic devices.In highly developed health care systems like those in Israel, the United States, and Europe, most aspects of the health care and consumer health experience are becoming supported by a wide array of technology such as electronic and personal health records (EHRs and PHRs), biometric & telemedicine devices, and consumer-focused wireless and wired Internet applications.In an article in this issue, Peleg and Nazarenko report on a survey they fielded within Israel's largest integrated delivery system regarding patient views on the use of electronic communication with their doctors via direct-access mobile phones and e-mail. A previous complementary paper describes the parallel perspectives of the physician staff at the same organization. These two surveys offer useful insights to clinicians, managers, researchers, and policymakers on how best to integrate e-mail and direct-to-doctor mobile phones into their practice settings. These papers, along with several other recent Israeli studies on e-health, also provide an opportunity to step back and take stock of the dramatic impact that information & communication technology (ICT) and health information technology (HIT) will have on clinician/patient communication moving forward.The main goals of this commentary are to describe the scope of this issue and to offer a framework for understanding the potential impact that e-health tools will have on provider/patient communication. It will be essential that clinicians, managers, policymakers, and researchers gain an increased understanding of this trend so that health care systems around the globe can adapt, adopt, and embrace these rapidly

The electroencephalogram (EEG) is modified by motor imagery and can be used by patients with severe motor impairments (e.g., late stage of amyotrophic lateral sclerosis) to communicate with their environment. Such a direct connection between the brain and the computer is known as an EEG-based brain-computer interface (BCI). This paper describes a new type of BCI system that uses rapid prototyping to enable a fast transition of various types of parameter estimation and classification algorithms to real-time implementation and testing. Rapid prototyping is possible by using Matlab, Simulink, and the Real-Time Workshop. It is shown how to automate real-time experiments and perform the interplay between on-line experiments and offline analysis. The system is able to process multiple EEG channels on-line and operates under Windows 95 in real-time on a standard PC without an additional digital signal processor (DSP) board. The BCI can be controlled over the Internet, LAN or modem. This BCI was tested on 3 subjects whose task it was to imagine either left or right hand movement. A classification accuracy between 70% and 95% could be achieved with two EEG channels after some sessions with feedback using an adaptive autoregressive (AAR) model and linear discriminant analysis (LDA).

Orchestrating rapid long-distance signaling in plants with Ca2+ , ROS and electrical signals.

2017-05-01

Plants show a rapid systemic response to a wide range of environmental stresses, where the signals from the site of stimulus perception are transmitted to distal organs to elicit plant-wide responses. A wide range of signaling molecules are trafficked through the plant, but a trio of potentially interacting messengers, reactive oxygen species (ROS), Ca 2+ and electrical signaling ('trio signaling') appear to form a network supporting rapid signal transmission. The molecular components underlying this rapid communication are beginning to be identified, such as the ROS producing NAPDH oxidase RBOHD, the ion channel two pore channel 1 (TPC1), and glutamate receptor-like channels GLR3.3 and GLR3.6. The plant cell wall presents a plant-specific route for possible propagation of signals from cell to cell. However, the degree to which the cell wall limits information exchange between cells via transfer of small molecules through an extracellular route, or whether it provides an environment to facilitate transmission of regulators such as ROS or H + remains to be determined. Similarly, the role of plasmodesmata as both conduits and gatekeepers for the propagation of rapid cell-to-cell signaling remains a key open question. Regardless of how signals move from cell to cell, they help prepare distant parts of the plant for impending challenges from specific biotic or abiotic stresses. © 2017 The Authors The Plant Journal © 2017 John Wiley & Sons Ltd.

Using grounded theory methodology to conceptualize the mother-infant communication dynamic: potential application to compliance with infant feeding recommendations.

PubMed

Waller, Jennifer; Bower, Katherine M; Spence, Marsha; Kavanagh, Katherine F

2015-10-01

Excessive, rapid weight gain in early infancy has been linked to risk of later overweight and obesity. Inappropriate infant feeding practices associated with this rapid weight gain are currently of great interest. Understanding the origin of these practices may increase the effectiveness of interventions. Low-income populations in the Southeastern United States are at increased risk for development of inappropriate infant feeding practices, secondary to the relatively low rates of breastfeeding reported from this region. The objective was to use grounded theory methodology (GTM) to explore interactions between mothers and infants that may influence development of feeding practices, and to do so among low-income, primiparous, Southeastern United States mothers. Analysis of 15 in-depth phone interviews resulted in development of a theoretical model in which Mother-Infant Communication Dynamic emerged as the central concept. The central concept suggests a communication pattern developed over the first year of life, based on a positive feedback loop, which is harmonious and results in the maternal perception of mother and infant now speaking the same language. Importantly, though harmonious, this dynamic may result from inaccurate maternal interpretation of infant cues and behaviours, subsequently leading to inappropriate infant feeding practices. Future research should test this theoretical model using direct observation of mother-infant communication, to increase the understanding of maternal interpretation of infant cues. Subsequently, interventions targeting accurate maternal interpretation of and response to infant cues, and impact on rate of infant weight gain could be tested. If effective, health care providers could potentially use these concepts to attenuate excess rapid infant weight gain. © 2013 John Wiley & Sons Ltd.

Starting in late 2007 and continuing through the present, NFIRE (Near-Field Infrared Experiment), a Missile Defense Agency (MDA) experimental satellite and TerraSAR-X, a German commercial SAR satellite have been conducting mutual crosslink experiments utilizing a secondary laser communication payload built by Tesat-Spacecom. The narrow laser beam-widths and high relative inter-spacecraft velocities for the two low-earth-orbiting satellites imply strict pointing control and dynamics aboard both vehicles. The satellites have achieved rapid communication acquisition times and maintained communication for hundreds of seconds before losing line of sight to the counter satellite due to earth blockage. Through post-mission analysis and other related telemetry we will show results for pointing accuracy, disturbance environments and pre-engagement prediction requirements that support successful and reliable operations.

Distributed communication: Implications of cultural-historical activity theory (CHAT) for communication disorders.

PubMed

Hengst, Julie A

2015-01-01

This article proposes distributed communication as a promising theoretical framework for building supportive environments for child language development. Distributed communication is grounded in an emerging intersection of cultural-historical activity theory (CHAT) and theories of communicative practices that argue for integrating accounts of language, cognition and culture. The article first defines and illustrates through selected research articles, three key principles of distributed communication: (a) language and all communicative resources are inextricably embedded in activity; (b) successful communication depends on common ground built up through short- and long-term histories of participation in activities; and (c) language cannot act alone, but is always orchestrated with other communicative resources. It then illustrates how these principles are fully integrated in everyday interactions by drawing from my research on Cindy Magic, a verbal make-believe game played by a father and his two daughters. Overall, the research presented here points to the remarkably complex communicative environments and sophisticated forms of distributed communication children routinely engage in as they interact with peer and adult communication partners in everyday settings. The article concludes by considering implications of these theories for, and examples of, distributed communication relevant to clinical intervention. Readers will learn about (1) distributed communication as a conceptual tool grounded in an emerging intersection of cultural-historical activity theory and theories of communicative practices and (2) how to apply distributed communication to the study of child language development and to interventions for children with communication disorders.

The 80h work week has raised concerns that complications may increase due to multiple sign-outs or poor communication. Trauma Surgery manages complex trauma and acute care surgical patients with rapidly changing physiology, clinical demands and a large volume of data that must be communicated to render safe, effective patient care. Trauma Morning Report format may offer the ideal situation to study and teach sign-outs and resident communication. Surgery Residents were assessed on a 1-5 scale for their ability to communicate to their fellow residents. This consisted of 10 critical points of the presentation, treatment and workup from the previous night's trauma admissions. Scores were grouped into three areas. Each area was scored out of 15. Area 1 consisted of Initial patient presentation. Area 2 consisted of events in the trauma bay. Area 3 assessed clarity of language and ability to communicate to their fellow residents. The residents were assessed for inclusion of pertinent positive and negative findings, as well as overall clarity of communication. In phase 1, residents were unaware of the evaluation process. Phase 2 followed a series of resident education session about effective communication, sign-out techniques and delineation of evaluation criteria. Phase 3 was a resident-blinded phase which evaluated the sustainability of the improvements in resident communication. 50 patient presentations in phase 1, 200 in phase 2, and 50 presentations in phase 3 were evaluated. Comparisons were made between the Phase 1 and Phase 2 evaluations. Area 1 (initial events) improved from 6.18 to 12.4 out of 15 (p<0.0001). Area 2 (events in the trauma bay) improved from 9.78 to 16.53 (p<0.0077). Area 3 (communication and language) improved from 8.36 to 12.22 out of 15 (P<0.001). Phase 2 to Phase 3 evaluations were similar, showing no deterioration of skills. Trauma Surgery manages complex surgical patients, with rapidly changing physiologic and clinical demands.

Rapid Response Teams aim to accelerate recognition and treatment of acutely unwell patients. Delays in delivery might undermine efficiency of the intervention. Our understanding of the causes of these delays is, as yet, incomplete. To identify modifiable causes of delays in the treatment of critically ill patients outside intensive care with a focus on factors amenable to system design. Review of care records and direct observation with process mapping of care delivered to 17 acutely unwell patients attended by a Rapid Response Team in a District General Hospital in the United Kingdom. Delays were defined as processes with no added value for patient care. Essential diagnostic and therapeutic procedures accounted for only 31% of time of care processes. Causes for delays could be classified into themes as (1) delays in call-out of the Rapid Response Team, (2) problems with team cohesion including poor communication and team efficiency and (3) lack of resources including lack of first line antibiotics, essential equipment, experienced staff and critical care beds. We identified a number of potentially modifiable causes for delays in care of acutely ill patients. Improved process design could include automated call-outs, a dedicated kit for emergency treatment in relevant clinical areas, increased usage of standard operating procedures and staff training using crew resource management techniques.

Abstract Background Many countries are on the brink of establishing antibiotic stewardship programmes in hospitals nationwide. In a previous study we found that communication between microbiology laboratories and clinical units is a barrier to implementing efficient antibiotic stewardship programmes in Norway. We have now addressed the key communication barriers between microbiology laboratories and clinical units from a laboratory point of view. Methods Qualitative semi-structured interviews were conducted with 18 employees (managers, doctors and technicians) from six diverse Norwegian microbiological laboratories, representing all four regional health authorities. Interviews were recorded and transcribed verbatim. Thematic analysis was applied, identifying emergent themes, subthemes and corresponding descriptions. Results The main barrier to communication is disruption involving specimen logistics, information on request forms, verbal reporting of test results and information transfer between poorly integrated IT systems. Furthermore, communication is challenged by lack of insight into each other’s area of expertise and limited provision of laboratory services, leading to prolonged turnaround time, limited advisory services and restricted opening hours. Conclusions Communication between microbiology laboratories and clinical units can be improved by a review of testing processes, educational programmes to increase insights into the other’s area of expertise, an evaluation of work tasks and expansion of rapid and point-of-care test services. Antibiotic stewardship programmes may serve as a valuable framework to establish these measures. PMID:28633405

Polar Cooperative Navigation Algorithm for Multi-Unmanned Underwater Vehicles Considering Communication Delays.

To solve the navigation accuracy problems of multi-Unmanned Underwater Vehicles (multi-UUVs) in the polar region, a polar cooperative navigation algorithm for multi-UUVs considering communication delays is proposed in this paper. UUVs are important pieces of equipment in ocean engineering for marine development. For UUVs to complete missions, precise navigation is necessary. It is difficult for UUVs to establish true headings because of the rapid convergence of Earth meridians and the severe polar environment. Based on the polar grid navigation algorithm, UUV navigation in the polar region can be accomplished with the Strapdown Inertial Navigation System (SINS) in the grid frame. To save costs, a leader-follower type of system is introduced in this paper. The leader UUV helps the follower UUVs to achieve high navigation accuracy. Follower UUVs correct their own states based on the information sent by the leader UUV and the relative position measured by ultra-short baseline (USBL) acoustic positioning. The underwater acoustic communication delay is quantized by the model. In this paper, considering underwater acoustic communication delay, the conventional adaptive Kalman filter (AKF) is modified to adapt to polar cooperative navigation. The results demonstrate that the polar cooperative navigation algorithm for multi-UUVs that considers communication delays can effectively navigate the sailing of multi-UUVs in the polar region.

Scientists are increasingly using Twitter as a tool for communicating science. Twitter can promote scholarly discussion, disseminate research rapidly, and extend and diversify the scope of audiences reached. However, scientists also caution that if Twitter does not accurately convey science due to the inherent brevity of this media, misinformation could cascade quickly through social media. Data on whether Twitter effectively communicates conservation science and the types of user groups receiving these tweets are lacking. To address these knowledge gaps, we examined live tweeting as a means of communicating conservation science at the 2013 International Congress for Conservation Biology (ICCB). We quantified and compared the user groups sending and reading live tweets. We also surveyed presenters to determine their intended audiences, which we compared with the actual audiences reached through live tweeting. We also asked presenters how effectively tweets conveyed their research findings. Twitter reached 14 more professional audience categories relative to those attending and live tweeting at ICCB. However, the groups often reached through live tweeting were not the presenters' intended audiences. Policy makers and government and non-governmental organizations were rarely reached (0%, 4%, and 6% of audience, respectively), despite the intent of the presenters. Plenary talks were tweeted about 6.9 times more than all other oral or poster presentations combined. Over half the presenters believed the tweets about their talks were effective. Ineffective tweets were perceived as vague or missing the presenters' main message. We recommend that presenters who want their science to be communicated accurately and broadly through Twitter should provide Twitter-friendly summaries that incorporate relevant hashtags and usernames. Our results suggest that Twitter can be used to effectively communicate speakers' findings to diverse audiences beyond conference walls. © 2015

Elements of effective palliative care models: a rapid review

PubMed Central

2014-01-01

Background Population ageing, changes to the profiles of life-limiting illnesses and evolving societal attitudes prompt a critical evaluation of models of palliative care. We set out to identify evidence-based models of palliative care to inform policy reform in Australia. Method A rapid review of electronic databases and the grey literature was undertaken over an eight week period in April-June 2012. We included policy documents and comparative studies from countries within the Organisation for Economic Co-operation and Development (OECD) published in English since 2001. Meta-analysis was planned where >1 study met criteria; otherwise, synthesis was narrative using methods described by Popay et al. (2006). Results Of 1,959 peer-reviewed articles, 23 reported systematic reviews, 9 additional RCTs and 34 non-randomised comparative studies. Variation in the content of models, contexts in which these were implemented and lack of detailed reporting meant that elements of models constituted a more meaningful unit of analysis than models themselves. Case management was the element most consistently reported in models for which comparative studies provided evidence for effectiveness. Essential attributes of population-based palliative care models identified by policy and addressed by more than one element were communication and coordination between providers (including primary care), skill enhancement, and capacity to respond rapidly to individuals’ changing needs and preferences over time. Conclusion Models of palliative care should integrate specialist expertise with primary and community care services and enable transitions across settings, including residential aged care. The increasing complexity of care needs, services, interventions and contextual drivers warrants future research aimed at elucidating the interactions between different components and the roles played by patient, provider and health system factors. The findings of this review are limited by its

Though research has begun to highlight the centrality of communication in palliative care, studies have yet to focus on the use of mindful communication. Mindful communication is associated with increases in patient care and decreases in physician burnout. Through in-depth, semi-structured interviews the authors sought mindful communication practices from palliative care leaders in American Hospital Association Circle of Life® award-wining units. Four key mindful communication practices emerged: Know your audience, ask questions, discard scripts, and recognize your role. The discussion articulates how key mindful communication practices may be used as a stage model, where key practices may be used individually or in concert, by sole practitioners or within interdisciplinary teams and by new and seasoned clinicians. Theoretical contributions and areas for future inquiry are also discussed.

Rapid development of information and communications technologies (ICT) has triggered profound changes in how people manage their social contacts in both informal and professional contexts. ICT mediated communication may seem limited in possibilities compared to face-to-face encounters, but research shows that puzzlingly often it can be just as effective and satisfactory. We posit that ICT users employ specific communication strategies adapted to particular communication channels, which results in a comparable effectiveness of communication. In order to maintain a satisfactory level of conversational intelligibility they calibrate the content of their messages to a given medium's richness and adjust the whole conversation trajectory so that every stage of the communication process runs fluently. In the current study, we compared complex task solving trajectories in chat, mobile phone and face-to-face dyadic conversations. Media conditions did not influence the quality of decision outcomes or users' perceptions of the interaction, but they had impact on the amount of time devoted to each of the identified phases of decision development. In face-to-face contacts the evaluation stage of the discussion dominated the conversation; in the texting condition the orientation-evaluation-control phases were evenly distributed; and the phone condition provided a midpoint between these two extremes. The results show that contemporary ICT users adjust their communication behavior to the limitations and opportunities of various media through the regulation of attention directed to each stage of the discussion so that as a whole the communication process remains effective.

Exponential Communication Complexity Advantage from Quantum Superposition of the Direction of Communication

NASA Astrophysics Data System (ADS)

Guérin, Philippe Allard; Feix, Adrien; Araújo, Mateus; Brukner, Časlav

2016-09-01

In communication complexity, a number of distant parties have the task of calculating a distributed function of their inputs, while minimizing the amount of communication between them. It is known that with quantum resources, such as entanglement and quantum channels, one can obtain significant reductions in the communication complexity of some tasks. In this work, we study the role of the quantum superposition of the direction of communication as a resource for communication complexity. We present a tripartite communication task for which such a superposition allows for an exponential saving in communication, compared to one-way quantum (or classical) communication; the advantage also holds when we allow for protocols with bounded error probability.

Integrating design science theory and methods to improve the development and evaluation of health communication programs.

PubMed

Neuhauser, Linda; Kreps, Gary L

2014-12-01

Traditional communication theory and research methods provide valuable guidance about designing and evaluating health communication programs. However, efforts to use health communication programs to educate, motivate, and support people to adopt healthy behaviors often fail to meet the desired goals. One reason for this failure is that health promotion issues are complex, changeable, and highly related to the specific needs and contexts of the intended audiences. It is a daunting challenge to effectively influence health behaviors, particularly culturally learned and reinforced behaviors concerning lifestyle factors related to diet, exercise, and substance (such as alcohol and tobacco) use. Too often, program development and evaluation are not adequately linked to provide rapid feedback to health communication program developers so that important revisions can be made to design the most relevant and personally motivating health communication programs for specific audiences. Design science theory and methods commonly used in engineering, computer science, and other fields can address such program and evaluation weaknesses. Design science researchers study human-created programs using tightly connected build-and-evaluate loops in which they use intensive participatory methods to understand problems and develop solutions concurrently and throughout the duration of the program. Such thinking and strategies are especially relevant to address complex health communication issues. In this article, the authors explore the history, scientific foundation, methods, and applications of design science and its potential to enhance health communication programs and their evaluation.

Matuszyk, Iwona; Rymkiewicz, Bartosz

2018-03-01

Financial and non-financial reporting from the beginning of its existence is the primary source of communication between the company and a wide range of stakeholders. Over the decades it has adapted to the needs of rapidly changing business and social environment. Currently, the final link in the evolution of organizational reporting, such as integrated reporting, assumes integration and mutual connectivity to both financial and non-financial data. The main interest in the concept of integrated reporting comes from the value it contributes to the organization. Undoubtedly, the concept of integrated reporting is a milestone in the evolution of organizational reporting. It is however important to consider whether it adequately addresses the information needs of a wide range of stakeholders, and whether it is a universal tool for communication between the company and its stakeholders. The aim of the paper is to discuss the advantages and disadvantages of the concept of integrated reporting as a tool for communication with stakeholders and to further directions of its development. The article uses the research methods such as literature analysis, the content analysis of the corporate publications and comparative analysis.

Public opinion and communicative action around renewable energy projects

NASA Astrophysics Data System (ADS)

Fast, Stewart

This thesis investigates how rural communities negotiate the development of renewable energy projects. Public and local community acceptance of these new technologies in rural areas around the world is uncertain and spatially uneven and represents an area of emerging public policy interest and one where scholarly theory is rapidly developing. This thesis uses Habermasian concepts of public sphere, communicative action and deliberative democracy, as well as the concept of "wicked problems" from the planning studies literature combined with geographical concepts of place and scale to advance theoretical and empirical understanding of how public opinion on renewable energy technologies is formed in place. It documents energy use patterns, attitudes and socio-political relations at a time when considerable state and business efforts are directed at the construction of solar, wind, biomass and small-hydro technologies in rural regions. These concepts and theories are applied in a case study of rural communities in the Eastern Ontario Highlands, an impoverished area undergoing rapid restructuring driven by centralization of services and amenity migration but with abundant natural resources in form of forests, numerous waterways and open space which have attracted a broad range of new energy developments. Overall high levels of support for alternative energy development particularly for solar power were found, albeit for reasons of local energy security and not for reasons of preventing climate change. There was some evidence that seasonal residents are less supportive of hydro and biomass projects than permanent residents possibly reflecting broader trends in rural economies away from productive uses of land to consumptive appreciation of rural landscapes. The thesis suggests that collective action to advance energy projects in the case study area require agreement along three world-claims (truth, rightness and truthfulness) and that communication leading to discourse

Koivunen, Marita; Niemi, Anne; Hupli, Maija

2015-03-01

The aim of the study is to describe nursing professionals' experiences of the use of electronic devices for communication with colleagues and other healthcare professionals. Information and communication technology applications in health care are rapidly expanding, thanks to the fast-growing penetration of the Internet and mobile technology. Communication between professionals in health care is essential for patient safety and quality of care. Implementing new methods for communication among healthcare professionals is important. A cross-sectional survey was used in the study. The data were collected in spring 2012 using an electronic questionnaire with structured and open-ended questions. The target group comprised the nursing professionals (N = 567, n = 123) in one healthcare district who worked in outpatient clinics in publically funded health care in Finland. Nursing professionals use different electronic devices for communication with each other. The most often used method was email, while the least used methods were question-answer programmes and synchronous communication channels on the Internet. Communication using electronic devices was used for practical nursing, improving personnel competences, organizing daily operations and administrative tasks. Electronic devices may speed up the management of patient data, improve staff cooperation and competence and make more effective use of working time. The obstacles were concern about information security, lack of technical skills, unworkable technology and decreasing social interaction. According to our findings, despite the obstacles related to use of information technology, the use of electronic devices to support communication among healthcare professionals appears to be useful. © 2014 John Wiley & Sons Ltd.

College students' use of communication technology with parents: comparisons between two cohorts in 2009 and 2011.

Although communication technology is beneficial to maintain important close relationships, not all findings suggest that communication technology use between college students and their parents is indicative of positive adjustment or relational qualities. A study in 2009 found that only 24.2% of college students used a social networking site (SNS) to communicate with a parent, yet those students reported more loneliness, anxious attachment, and conflict with their parent (Gentzler et al., 2011 ). Because technology and trends in use change rapidly, we investigated a new cohort of college students 2 years later to determine if rates of using communication technology with parents and their links to student adjustment have changed. Comparisons between 2009 and 2011 samples indicated that in-person contact and telephone use did not vary across cohorts. However, texting and SNS use with parents became more common, and using e-mail with parents declined. Consistent with the 2009 data, students' phone use with parents was related to positive relationship qualities (satisfaction, intimacy, support, instrumental aid). In the new 2011 sample, e-mail was linked to aid. However, the present findings indicate students' SNS use with parents is no longer linked to maladaptive outcomes. The study highlights how quickly the use and implications of communication technology changes, and suggests that communication patterns may reflect broader psychosocial adjustment and parent-child dynamics.

Augmentative and alternative communication (AAC) social media research is relatively new, and is built on a foundation of research on use of the Internet and social media by people with communication disabilities. Although the field is expanding to include a range of people who use AAC, there are limitations and gaps in research that will need to be addressed in order to keep pace with the rapid evolution of social media connectivity in assistive communication technologies. In this paper, we consider the aims, scope, and methodologies of AAC social media research, with a focus on social network sites. Lack of detailed attention to specific social network sites and little use of social media data limits the extent to which findings can be confirmed. Increased use of social media data across a range of platforms, including Instagram and YouTube, would provide important insights into the lives of people who use AAC and the ways in which they and their supporters use social media. New directions for AAC social media research are presented in line with those discussed at the social media research symposium at the International Society for Augmentative and Alternative Communication in Toronto, Canada, on August 12, 2016.

Telehomecare Communication and Self-Care in Chronic Conditions: Moving Towards a Shared Understanding

PubMed Central

Shea, Kimberly; Chamoff, Breanna

2012-01-01

Background Remote telemonitoring of patients’ vital signs is a rapidly increasing practice. While methods of communication in remote electronic monitoring differ from those in traditional home health care, the understanding shared by the nurse, patient, and family members remains the same: patients’ self-care behaviors affect exacerbations of chronic health conditions. The purpose of this paper is to examine the relationship between communication and information integration into the daily lives of patients with chronic illnesses and offer best practice recommendations for telehomecare nurses. Methods The original study utilized the Social Relations Model to examine relationships within 43 triads composed of patients with chronic conditions, home helpers and their nurse (THN) involved in telehomecare at three Veterans Health Administrations. This secondary descriptive and correlational analysis compared 43 patients’ and 9 THNs’ ratings of themselves and each other on communication (frequency, timeliness and understanding) and the use of patients’ daily telemonitored information. Results There was almost no correlation between patients’ perception of THNs’ communication (frequency [r = .05], timeliness [r = .09] and understandability [r = .03]) and patients’ integration of information into daily health practices. However, significant correlations were found between the THNs’ perception of patients’ communication frequency and timeliness, and integration, (p = .02), (p < .001) respectively. Conclusions This study suggests that frequent phone communication may lead the remote THN to believe patients are integrating blood pressure, weight and other information into daily self-care behaviors, when in fact the patient reports that they are not. The influence of a halo effect on the THN may cloud an accurate perception of what is actually occurring. Remote communication may require more attention to THNs educating patients about shared understandings

1994-06-01

Personal Communications Services (PCS) may be the key ingredient for vastly improved military communications capabilities at the turn of the century. The Federal Communications Commission (FCC) defines PCS as a family of mobile or portable radio communications services which could provide services to individuals and businesses and be integrated with a variety of competing networks ... the primary focus of PCS will be to meet communications requirements of people on the move. Today's generation of Theater Deployable Communications, which provides joint tactical communications to deployed forces, is the Tri-Service Tactical Communications (TRI-TAC) system. A description of TRITAC's family of equipment, network topology, typical employment, and critical limitations is presented in this thesis. Five commercial Mobile Satellite Services (MSS) are described as viable candidates for augmenting existing communications systems. Cellular design principles such as frequency reuse, cell splitting, channel access methods, and propagation factors are also addressed. Finally, a framework for comparison of the candidate MSS systems is proposed as a baseline for further studies into the most beneficial implementation of PCS into theater deployable communications systems for the future.

Rapid Airplane Parametric Input Design (RAPID)

NASA Technical Reports Server (NTRS)

Smith, Robert E.

1995-01-01

RAPID is a methodology and software system to define a class of airplane configurations and directly evaluate surface grids, volume grids, and grid sensitivity on and about the configurations. A distinguishing characteristic which separates RAPID from other airplane surface modellers is that the output grids and grid sensitivity are directly applicable in CFD analysis. A small set of design parameters and grid control parameters govern the process which is incorporated into interactive software for 'real time' visual analysis and into batch software for the application of optimization technology. The computed surface grids and volume grids are suitable for a wide range of Computational Fluid Dynamics (CFD) simulation. The general airplane configuration has wing, fuselage, horizontal tail, and vertical tail components. The double-delta wing and tail components are manifested by solving a fourth order partial differential equation (PDE) subject to Dirichlet and Neumann boundary conditions. The design parameters are incorporated into the boundary conditions and therefore govern the shapes of the surfaces. The PDE solution yields a smooth transition between boundaries. Surface grids suitable for CFD calculation are created by establishing an H-type topology about the configuration and incorporating grid spacing functions in the PDE equation for the lifting components and the fuselage definition equations. User specified grid parameters govern the location and degree of grid concentration. A two-block volume grid about a configuration is calculated using the Control Point Form (CPF) technique. The interactive software, which runs on Silicon Graphics IRIS workstations, allows design parameters to be continuously varied and the resulting surface grid to be observed in real time. The batch software computes both the surface and volume grids and also computes the sensitivity of the output grid with respect to the input design parameters by applying the precompiler tool

The growing problem of antibiotic resistance underlies the critical need to develop new treatments to prevent and control resistant bacterial infection. Exogenous application of bacteriophage lysins results in rapid and specific destruction of Gram-positive bacteria and therefore lysins represent novel antibacterial agents. The PlyC phage lysin is the most potent lysin characterized to date and can rapidly lyse Group A, C and E streptococci. Previously, we have determined the X-ray crystal structure of PlyC, revealing a complicated and unique arrangement of nine proteins. The scaffold features a multimeric cell-wall docking assembly bound to two catalytic domains that communicate and work synergistically. However, the crystal structure appeared to be auto-inhibited and raised important questions as to the mechanism underlying its extreme potency. Here we use small angle X-ray scattering (SAXS) and reveal that the conformational ensemble of PlyC in solution is different to that in the crystal structure. We also investigated the flexibility of the enzyme using both normal mode (NM) analysis and molecular dynamics (MD) simulations. Consistent with our SAXS data, MD simulations show rotational dynamics of both catalytic domains, and implicate inter-domain communication in achieving a substrate-ready conformation required for enzyme function. Our studies therefore provide insights into how the domains in the PlyC holoenzyme may act together to achieve its extraordinary potency. PMID:26470022

Google the question, “How is the Internet changing the way we communicate?,” and you will find no shortage of opinions, or fears, about the Internet altering the way we communicate. Although the Internet is not necessarily making communication briefer (neither is the Internet making communication less formal), the Internet is manifesting our preference for writing over speaking. I propose that our preference for communicating through Internet-based text derives from a fundamental feature of writing: In contrast to speech, which is most often synchronous, text is most often asynchronous.

We present evidence that the agr cell-to-cell communication system is present across firmicutes, including the human pathogen Clostridium perfringens. Although we find that the agr system is evolutionarily conserved and that the general functions which it regulates are similar in different species, the individual regulated genes are not the same. This suggests that the regulatory network controlled by agr is dynamic and evolves rapidly. PMID:17933897

As droughts continue to impact businesses and communities throughout the United States, there needs to be a greater emphasis on drought communication through interdisciplinary approaches, risk communication, and digital platforms. The purpose of this research is to provide an overview of the current literature on communicating drought and suggests areas for further improvement. Specifically, this research focuses on communicating drought through social media platforms such as Facebook, Twitter, and Instagram. It also focuses on the conglomeration of theoretical frameworks within the realm of risk communication, to provide a strong foundation towards future drought communication. This research proposal provides a critical step to advocate for paradigmatic shifts within natural hazard communication.

Ethics of clinician communication in a changing communication landscape: guidance from professional societies.

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

Poor management communication in healthcare services affects employees' motivation, commitment, and, in the final instance, organizational performance and the quality of patient care. In any area of health management, good communication is, therefore, key to successful management. This article discusses how managers of ambulance stations should secure communication with their paramedic crews. The first part uses ethical concepts to analyze communicative disagreement in interactive dialogue between managers and paramedics. The second part outlines basic communication principles that can serve as conceptual tools for avoiding misinterpretation in prehospital manager-employee interaction.

Two schemes for rapid generation of digital video holograms using PC cluster

NASA Astrophysics Data System (ADS)

Park, Hanhoon; Song, Joongseok; Kim, Changseob; Park, Jong-Il

2017-12-01

Computer-generated holography (CGH), which is a process of generating digital holograms, is computationally expensive. Recently, several methods/systems of parallelizing the process using graphic processing units (GPUs) have been proposed. Indeed, use of multiple GPUs or a personal computer (PC) cluster (each PC with GPUs) enabled great improvements in the process speed. However, extant literature has less often explored systems involving rapid generation of multiple digital holograms and specialized systems for rapid generation of a digital video hologram. This study proposes a system that uses a PC cluster and is able to more efficiently generate a video hologram. The proposed system is designed to simultaneously generate multiple frames and accelerate the generation by parallelizing the CGH computations across a number of frames, as opposed to separately generating each individual frame while parallelizing the CGH computations within each frame. The proposed system also enables the subprocesses for generating each frame to execute in parallel through multithreading. With these two schemes, the proposed system significantly reduced the data communication time for generating a digital hologram when compared with that of the state-of-the-art system.

2014-01-01

The aim of the study was to explore the communication experiences of key communications partners (CPs) of individuals receiving home mechanical ventilation (HMV), with particular emphasis on the possibilities, difficulties and limitations CPs experienced in communication, possible support given to facilitate communication and exploring what made a skilled communicator. A qualitative research design using interviews was used. The participants included 19 key CPs of individuals receiving HMV. The analysis resulted in five themes: Encountering communication limitations, Functional communication strategies, Being a communication facilitator, Role insecurity and Emotional reactions and coping. The findings revealed that CPs needed to develop partly new reference frames for communication. In particular, participants emphasised the need to understand and interpret subtle details in the communicative interaction. The findings are discussed in the light of previous research, in particular an earlier study exploring another perspective; the ventilator-supported individuals' experiences of communication. Issues relating to the educational needs of CPs of individuals receiving HMV are discussed. The results are intended to enhance understanding of the challenges that individuals receiving HMV and their CPs face with communication, which should be of relevance not only to speech therapists, but for all healthcare practitioners in the field of HMV.

Effective science communication can open doors, accelerate your career and even make you a better scientist. Part of being an effective and productive scientist means being an effective science communicator. The scientist must communicate their work in talks, posters, peer-reviewed papers, internal reports, proposals as well as to the broader public (including law makers). Despite the importance of communication, it has traditionally not been part of our core training as scientists. Today's science students are beginning to have more opportunities to formally develop their science communication skills. Fortunately, new and even more established scientists have a range of tools and resources at their disposal. In this presentation, we will share some of these resources, share our own experiences utilizing them, and provide some practical tools to improve your own science communication skills.

current set of standard CCSDS data communications protocols can be incrementally evolved so that true InterPlaNetary Internet operations are feasible by the end of the decade. The strategy - which is already in progress via the deployment of Mars relay links - needs individual missions to each contribute increments of capability so that a standard communications infrastructure can rapidly accrete. This paper will describe the IPN architectural concepts, discuss the current set of standard data communications capabilities that exist to support Mars exploration and review the proposed new developments. We will also postulate that the concept is scalable and can grow to support future scenarios where human intelligence is widely distributed across the Solar System and day-to-day communications dialog among planets is routine. 1 2 3 4 5

2014-04-01

The adoption of social media technologies appears to enhance clinical outcomes through improved communications as reported by Bacigalupe (Fam Syst Heal 29(1):1-14, 2011). The ability of providers to more effectively, directly, and rapidly communicate among themselves as well as with patients should strengthen collaboration and treatment as reported by Bacigalupe (Fam Syst Heal 29(1):1-14, 2011). This paper is a case study in one organization's development of an internally designed and developed social technology solution termed "Unite." The Unite system combines social technologies' features including push notifications, messaging, community groups, and user lists with clinical workflow and applications to construct dynamic provider networks, simplify communications, and facilitate clinical workflow optimization. Modeling Unite as a social technology may ease adoption barriers. Developing a social network that is integrated with healthcare information systems in the clinical space opens the doors to capturing and studying the way in which providers communicate. The Unite system appears to have the potential to breaking down existing communication paradigms. With Unite, a rich set of usage data tied to clinical events may unravel alternative networks that can be leveraged to advance patient care.

Rapid prototyping technology is used to fabricate three-dimensional (3D) brain arteriovenous malformation (AVM) models and facilitate presurgical patient communication and medical education for young surgeons. Two intracranial AVM cases were selected for this study. Using 3D CT angiography or 3D rotational angiography images, the brain AVM models were reconstructed on personal computer and the rapid prototyping process was completed using a 3D printer. The size and morphology of the models were compared to brain digital subtraction arteriography of the same patients. 3D brain AVM models were used for preoperative patient communication and young neurosurgeon education. Two brain AVM models were successfully produced. By neurosurgeons' evaluation, the printed models have high fidelity with the actual brain AVM structures of the patients. The patient responded positively toward the brain AVM model specific to himself. Twenty surgical residents from residency programs tested the brain AVM models and provided positive feedback on their usefulness as educational tool and resemblance to real brain AVM structures. Patient-specific 3D printed models of brain AVM can be constructed with high fidelity. 3D printed brain AVM models are proved to be helpful in preoperative patient consultation, surgical planning and resident training.

Early detection of bioterrorism requires assessment of diagnoses assigned to cases of rare diseases with which clinicians have little experience. In this study, we evaluated the process of defining the differential diagnosis for inhalational anthrax using electronic communication within a practice-based research network (PBRN) and compared the results with those obtained from a nationwide random sample of family physicians with a mailed instrument. We distributed survey instruments by e-mail to 55 physician members of the Wisconsin Research Network (WReN), a regional PBRN. The instruments consisted of 3 case vignettes randomly drawn from a set describing 11 patients with inhalational anthrax, 2 with influenza A, and 1 with Legionella pneumonia. Physicians provided their most likely nonanthrax diagnosis, along with their responses to 4 yes-or-no management questions for each case. Physicians who had not responded at 1 week received a second e-mail with the survey instrument. The comparison group consisted of the nationwide sample of physicians who completed mailed survey instruments. Primary outcome measures were response rate, median response time, and frequencies of diagnostic categories assigned to cases of inhalational anthrax. The PBRN response rate compared favorably with that of the national sample (47.3% vs 37.0%; P = not significant). The median response time for the PBRN was significantly shorter than that for the national sample (2 vs 28 days; P < .001). No significant differences were found between the PBRN and the Midwest subset of the national sample in the frequencies of major diagnostic categories or in case management. Electronic means of creating differential diagnoses for rare infectious diseases of national significance is feasible within PBRNs. Information is much more rapidly acquired and is consistent with that obtained by conventional methods.

National Aeronautics and Space Administration (NASA) CubeSat missions are expected to grow rapidly in the next decade. Higher data rate CubeSats are transitioning away from Amateur Radio bands to higher frequency bands. A high-level communication architecture for future space-to-ground CubeSat communication was proposed within NASA Goddard Space Flight Center. This architecture addresses CubeSat direct-to-ground communication, CubeSat to Tracking Data Relay Satellite System (TDRSS) communication, CubeSat constellation with Mothership direct-to-ground communication, and CubeSat Constellation with Mothership communication through K-Band Single Access (KSA). A study has been performed to explore this communication architecture, through simulations, analyses, and identifying technologies, to develop the optimum communication concepts for CubeSat communications. This paper presents details of the simulation and analysis that include CubeSat swarm, daughter ship/mother ship constellation, Near Earth Network (NEN) S and X-band direct to ground link, TDRSS Multiple Access (MA) array vs Single Access mode, notional transceiver/antenna configurations, ground asset configurations and Code Division Multiple Access (CDMA) signal trades for daughter ship/mother ship CubeSat constellation inter-satellite cross link. Results of space science X-band 10 MHz maximum achievable data rate study are summarized. CubeSat NEN Ka-Band end-to-end communication analysis is provided. Current CubeSat communication technologies capabilities are presented. Compatibility test of the CubeSat transceiver through NEN and SN is discussed. Based on the analyses, signal trade studies and technology assessments, the desired CubeSat transceiver features and operation concepts for future CubeSat end-to-end communications are derived.

A communication system for communicating over high-latency, low bandwidth networks includes a communications processor configured to receive a collection of data from a local system, and a transceiver in communication with the communications processor. The transceiver is configured to transmit and receive data over a network according to a plurality of communication parameters. The communications processor is configured to divide the collection of data into a plurality of data streams; assign a priority level to each of the respective data streams, where the priority level reflects the criticality of the respective data stream; and modify a communication parameter of at least one of the plurality of data streams according to the priority of the at least one data stream.

Secure satellite communication using multi-photon tolerant quantum communication protocol

2015-09-01

This paper proposes and analyzes the potential of a multi-photon tolerant quantum communication protocol to secure satellite communication. For securing satellite communication, quantum cryptography is the only known unconditionally secure method. A number of recent experiments have shown feasibility of satellite-aided global quantum key distribution (QKD) using different methods such as: Use of entangled photon pairs, decoy state methods, and entanglement swapping. The use of single photon in these methods restricts the distance and speed over which quantum cryptography can be applied. Contemporary quantum cryptography protocols like the BB84 and its variants suffer from the limitation of reaching the distances of only Low Earth Orbit (LEO) at the data rates of few kilobits per second. This makes it impossible to develop a general satellite-based secure global communication network using the existing protocols. The method proposed in this paper allows secure communication at the heights of the Medium Earth Orbit (MEO) and Geosynchronous Earth Orbit (GEO) satellites. The benefits of the proposed method are two-fold: First it enables the realization of a secure global communication network based on satellites and second it provides unconditional security for satellite networks at GEO heights. The multi-photon approach discussed in this paper ameliorates the distance and speed issues associated with quantum cryptography through the use of contemporary laser communication (lasercom) devices. This approach can be seen as a step ahead towards global quantum communication.

Improving Pathologists' Communication Skills.

2016-08-01

The 2015 Institute of Medicine report on diagnostic error has placed a national spotlight on the importance of improving communication among clinicians and between clinicians and patients [1]. The report emphasizes the critical role that communication plays in patient safety and outlines ways that pathologists can support this process. Despite recognition of communication as an essential element in patient care, pathologists currently undergo limited (if any) formal training in communication skills. To address this gap, we at the University of Washington Medical Center developed communication training with the goal of establishing best practice procedures for effective pathology communication. The course includes lectures, role playing, and simulated clinician-pathologist interactions for training and evaluation of pathology communication performance. Providing communication training can help create reliable communication pathways that anticipate and address potential barriers and errors before they happen. © 2016 American Medical Association.

Rapid development of information and communications technologies (ICT) has triggered profound changes in how people manage their social contacts in both informal and professional contexts. ICT mediated communication may seem limited in possibilities compared to face-to-face encounters, but research shows that puzzlingly often it can be just as effective and satisfactory. We posit that ICT users employ specific communication strategies adapted to particular communication channels, which results in a comparable effectiveness of communication. In order to maintain a satisfactory level of conversational intelligibility they calibrate the content of their messages to a given medium’s richness and adjust the whole conversation trajectory so that every stage of the communication process runs fluently. In the current study, we compared complex task solving trajectories in chat, mobile phone and face-to-face dyadic conversations. Media conditions did not influence the quality of decision outcomes or users’ perceptions of the interaction, but they had impact on the amount of time devoted to each of the identified phases of decision development. In face-to-face contacts the evaluation stage of the discussion dominated the conversation; in the texting condition the orientation-evaluation-control phases were evenly distributed; and the phone condition provided a midpoint between these two extremes. The results show that contemporary ICT users adjust their communication behavior to the limitations and opportunities of various media through the regulation of attention directed to each stage of the discussion so that as a whole the communication process remains effective.

Many countries are on the brink of establishing antibiotic stewardship programmes in hospitals nationwide. In a previous study we found that communication between microbiology laboratories and clinical units is a barrier to implementing efficient antibiotic stewardship programmes in Norway. We have now addressed the key communication barriers between microbiology laboratories and clinical units from a laboratory point of view. Qualitative semi-structured interviews were conducted with 18 employees (managers, doctors and technicians) from six diverse Norwegian microbiological laboratories, representing all four regional health authorities. Interviews were recorded and transcribed verbatim. Thematic analysis was applied, identifying emergent themes, subthemes and corresponding descriptions. The main barrier to communication is disruption involving specimen logistics, information on request forms, verbal reporting of test results and information transfer between poorly integrated IT systems. Furthermore, communication is challenged by lack of insight into each other's area of expertise and limited provision of laboratory services, leading to prolonged turnaround time, limited advisory services and restricted opening hours. Communication between microbiology laboratories and clinical units can be improved by a review of testing processes, educational programmes to increase insights into the other's area of expertise, an evaluation of work tasks and expansion of rapid and point-of-care test services. Antibiotic stewardship programmes may serve as a valuable framework to establish these measures. © The Author 2017.

The aim of this study was to develop an evidence-based communication skills training workshop to improve the communication skills of critical care fellows. Pulmonary and critical care fellows (N = 38) participated in a 3-day communication skills workshop between 2008 and 2010 involving brief didactic talks, faculty demonstration of skills, and faculty-supervised small group skills practice sessions with simulated families. Skills included the following: giving bad news, achieving consensus on goals of therapy, and discussing the limitations of life-sustaining treatment. Participants rated their skill levels in a pre-post survey in 11 core communication tasks using a 5-point Likert scale. Of 38 fellows, 36 (95%) completed all 3 days of the workshop. We compared pre and post scores using the Wilcoxon signed rank test. Overall, self-rated skills increased for all 11 tasks. In analyses by participant, 95% reported improvement in at least 1 skill; with improvement in a median of 10 of 11 skills. Ninety-two percent rated the course as either very good/excellent, and 80% recommended that it be mandatory for future fellows. This 3-day communication skills training program increased critical care fellows' self-reported family meeting communication skills. Copyright © 2014 Elsevier Inc. All rights reserved.

A New Remote Communications Link to Reduce Residential PV Solar Costs

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

King, Randy; Sugiyama, Rod

Monitoring of PV/DER site production is expensive to install and unreliable. Among third party systems providers, lost communications links are a growing concern. Nearly 20% of links are failing, provisioning is complex, recovery is expensive, production data is lost, and access is fragmented. FleetLink is a new concept in DER system communications, purpose built for lowering the cost of maintaining active contact with residential end user sites and ensuring that production data is reliably available to third party systems providers. Systems providers require accurate, secure system monitoring and reporting of production data and system faults while driving down overall costsmore » to compete effectively. This plug and play, independently operating communications solution lowers the cost of fleet contact from typically .08 dollars-$.12/W down to .02 dollars -.03/W including installation and maintenance expenses. FleetLink establishes a breakthrough in simplicity that facilitates rapid expansion of residential solar by reducing initial capital outlay and lowering installation labor time and skill levels. The solution also facilitates higher DER installation growth rates by driving down maintenance costs and eliminating communications trouble calls. This is accomplished by the FleetLink’s unique network technology that enables dynamic network configuration for fast changes, and active, self-healing DER site contact for uptime assurance. Using an open source network framework with proprietary, application specific enhancements, FleetLink independently manages connectivity, security, recovery, grid control communications, and fleet expansion while presenting a compliant SunSpec interface to the third party operations centers. The net system cost savings of at least .05 dollars/W supports the SunShot cost goals and the flexibility and scalability of the solution accelerates the velocity and ubiquitous adoption of solar.« less

Chemical shift imprint of intersubunit communication in a symmetric homodimer

PubMed Central

Falk, Bradley T.; Sapienza, Paul J.; Lee, Andrew L.

2016-01-01

Allosteric communication is critical for protein function and cellular homeostasis, and it can be exploited as a strategy for drug design. However, unlike many protein–ligand interactions, the structural basis for the long-range communication that underlies allostery is not well understood. This lack of understanding is most evident in the case of classical allostery, in which a binding event in one protomer is sensed by a second symmetric protomer. A primary reason why study of interdomain signaling is challenging in oligomeric proteins is the difficulty in characterizing intermediate, singly bound species. Here, we use an NMR approach to isolate and characterize a singly ligated state (“lig1”) of a homodimeric enzyme that is otherwise obscured by rapid exchange with apo and saturated forms. Mixed labeled dimers were prepared that simultaneously permit full population of the lig1 state and isotopic labeling of either protomer. Direct visualization of peaks from lig1 yielded site-specific ligand-state multiplets that provide a convenient format for assessing mechanisms of intersubunit communication from a variety of NMR measurements. We demonstrate this approach on thymidylate synthase from Escherichia coli, a homodimeric enzyme known to be half-the-sites reactive. Resolving the dUMP1 state shows that active site communication occurs not upon the first dUMP binding, but upon the second. Surprisingly, for many sites, dUMP1 peaks are found beyond the limits set by apo and dUMP2 peaks, indicating that binding the first dUMP pushes the enzyme ensemble to further conformational extremes than the apo or saturated forms. The approach used here should be generally applicable to homodimers. PMID:27466406

Communication predispositions influence interactions between individuals from different cultures. Three such predispositions have been found to affect behavior in intercultural contexts: Apprehension about intercultural communication, ethnocentrism, and intercultural willingness to communicate. This study examined differences between men (n = 130) and women (n = 175) on those three predispositions. The analysis showed that men reported experiencing higher apprehension about intercultural communication, being more ethnocentric than women, and being less willing to communicate interculturally than women. Implications of these findings are discussed.

Space communication is making immense strides since ECHO was launched in 1962. It was a simple passive reflector of signals that demonstrated the concept. Today, satellites incorporating transponders, sophisticated high-gain antennas, and stabilization systems provide voice, video, and data communications to millions of people nationally and worldwide. Applications of emerging technology, typified by NASA's Advanced Communications Technology Satellite (ACTS) to be launched in 1992, will use newer portions of the frequency spectrum (the Ka-band at 30/20 GHz), along with antennas and signal-processing that could open yet new markets and services. Government programs, directly or indirectly, are responsible for many space communications accomplishments. They are sponsored and funded in part by NASA and the U.S. Department of Defense since the early 1950s. The industry is growing rapidly and is achieving international preeminence under joint private and government sponsorship. Now, however, the U.S. space communications industry - satellite manufacturers and users, launch services providers, and communications services companies - are being forced to adapt to a different environment. International competition is growing, and terrestrial technologies such as fiber optics are claiming markets until recently dominated by satellites. At the same time, advancing technology is opening up opportunities for new applications and new markets in space exploration, for defense, and for commercial applications of several types. Space communications research, development, and applications (RD and A) programs need to adjust to these realities, be better coordinated and more efficient, and be more closely attuned to commercial markets. The programs must take advantage of RD and A results in other agencies - and in other nations.

The role of rapid antigen testing for influenza in the era of molecular diagnostics.

PubMed

Dale, Suzanne E

2010-08-01

Rapid antigen testing for influenza has been both maligned and revered since its conception. Microbiologists have long lamented the lack of sensitivity of commercial rapid influenza detection tests (RIDTs), whereas many clinicians have eschewed their utility by emphasizing the value of definitely diagnosing influenza at the patient's bedside. RIDTs, although quick and easy to perform, are widely accepted as being less sensitive than traditional culture techniques and newer molecular methods, including reverse-transcription polymerase chain reaction (RT-PCR). Moreover, the performance characteristics of RIDTs vary widely, and their applications as clinical diagnostic tools are not well understood. In contrast, traditional techniques are time consuming and require significant expertise to perform. Often, the delay in diagnosing influenza through these methods has little impact on patient care. The benefits of achieving a diagnosis of influenza at the point of care are numerous and include increased access to appropriate antivirals, appropriate patient cohorting for infection control purposes, and better resource utilization. Therefore, it behooves the microbiology community to communicate these issues to clinicians and to work to improve the sensitivity of RIDTs.

There is an overwhelming desire to create and enhance communication mechanisms between entities that operate within the National Airspace System. Furthermore, airlines are always extremely interested in increasing the efficiency of their flights. An innovative system prototype was developed and tested that improves collaborative decision making without modifying existing infrastructure or operational procedures within the current Air Traffic Management System. This system enables collaboration between flight crew and airline dispatchers to share and assess optimized flight routes through an Internet connection. Using a sophisticated medium-fidelity flight simulation environment, a rapid-prototyping development, and a unified modeling language, the software was designed to ensure reliability and scalability for future growth and applications. Ensuring safety and security were primary design goals, therefore the software does not interact or interfere with major flight control or safety systems. The system prototype demonstrated an unprecedented use of in-flight Internet to facilitate effective communication with Airline Operations Centers, which may contribute to increased flight efficiency for airlines.

Advances in the production of novel therapies for cancer management are creating new challenges for the support of increasing numbers of persons surviving for extended periods with advanced disease. Despite incurable and life-limiting metastatic conditions, these patients are living longer with serious disease, pushing the boundaries of what science explains and clinicians can confidently interpret using available evidence. Here we report findings from an early subset of such individuals within a longitudinal qualitative cancer cohort study on clinician-patient communication across the cancer trajectory. In these findings, we contextualize experiential accounts of communication in a changing environment of the costs and uncertainties of personalized medicine, and examine the complex psychosocial circumstances of this rapidly growing patient population. Interpretation of these findings illustrates how emerging issues in cancer treatment influence the experience of these patients, their social and support networks, their cancer care specialists, and the multidisciplinary teams charged with coordinating their care.

Methods A quality improvement project was undertaken to gather expert consensus on best practices that could be used to improve WHO protocols for disaster communication. Open-ended surveys of 26 WHO Communications Officers with disaster response experience were conducted. Responses were categorized to determine the common themes of disaster response communication and areas for practice improvement. Results Disasters where the participants had experience included 29 outbreaks of 13 different diseases in 16 countries, 18 natural disasters of 6 different types in 15 countries, 2 technical disasters in 2 countries, and ten conflicts in 10 countries. Conclusion Recommendations to build communications capacity prior to a disaster include pre-writing public service announcements in multiple languages on questions that frequently arise during disasters; maintaining a database of statistics for different regions and types of disaster; maintaining lists of the locally trusted sources of information for frequently affected countries and regions; maintaining email listservs of employees, international media outlet contacts, and government and non-governmental organization contacts that can be used to rapidly disseminate information; developing a global network with 24-h cross-coverage by participants from each time zone; and creating a central electronic sharepoint where all of these materials can be accessed by communications officers around the globe.

Risk communicators are often envisioned as government officials, public relations practitioners, or health workers. Yet much of the public's risk information comes from informal messages and unofficial carriers. Referred to in this study as "informal risk communicators" (IRCs), these individuals are often service workers who relay risk information to public audiences, though often outside of their formal job descriptions. Literatures in the health communication, science and technology studies, and risk communication fields have considered ideas relevant to explaining these individuals, and the risk communication work they perform. To further explore this category of individuals, this study examines the communicative practices of commercial pesticide applicators, using both in-depth interviews and surveys. Through their interactions with clients, these individuals offer care, as well as project expertise and identity; however, the extent to which this work is recognized and validated is less clear. Both applied and theoretical implications of this research are considered.

Cathode Anode Satellite Thruster for Orbital Reposition (CASTOR) is an orbital manoeuvre and transfer micro-satellite bus developed at MIT Space System Laboratory. The technical objective of the mission is achieving 1 km/s of delta-V over a 1 year mission in Low Earth Orbit (LEO). This will be accomplished using a novel electric propulsion system, the Diverging Cusped Field Thruster (DCFT), which enables high efficiency orbital changes of the ESPA-ring class satellite. CASTOR is capable of improving rapid access to space capabilities by providing an orbital transfer platform with a very high performance to mass ratio, thus greatly reducing launch costs and allowing for highly efficient orbital manoeuvre. Furthermore, CASTOR is highly scalable and modular, allowing it to be adapted to a wide range of scales and applications. CASTOR is developed as part of the University Nanosatellite Program (UNP) funded by Air Force Research Laboratory (AFRL). In order to accomplish CASTOR mission objective, a highly optimized, scalable, light weight, and low cost communication system needed to be developed. These constraints imply the development of trade studies to select the final communication system architecture able to maximize the amount of data transmitted, while guaranteeing reliability, redundancy and limited mass, power consumption, and cost. A special attention is also required to guarantee a reliable communication system in cases of tumbling, or in case of strong Doppler shift which is inevitable due to the high delta-V capabilities of the vehicle. In order to accomplish all the mission requirements, different features have been introduced in the design of the communication system for this mission. Specifically, customized patch antennas have been realized, and a customized communication protocol has been designed and implemented. The communication subsystem has been validated through an intense testing campaign which included software tests in the laboratory, hardware

The art of communication.

Effective communication is an essential skill in general practice consultations. The art of communication is the development of effective skills and finding a style of communication that suits the clinician and produces benefits for both patient and doctor. This paper outlines the essential skills required for effective communication with a patient and suggests that clinicians consider this communication as an art that can be developed throughout a medical career. Good communication can improve outcomes for patients and doctors, and deserves equal importance as developing clinical knowledge and procedural skill. The importance of good communication is so critical that Australian guidelines list effective communication as part of the required conduct for all doctors. A therapeutic patient-doctor relationship uses the clinician as a therapeutic intervention and is part of the art of communication. Despite all the technological advances of recent decades, caring, compassionate, healing doctors remain the best therapeutic tool in medicine. The ability of a doctor to provide comfort through their presence and their words is a fundamental component of good medical care.

Towards reporting standards for neuropsychological study results: A proposal to minimize communication errors with standardized qualitative descriptors for normalized test scores.

Rapid, clear and efficient communication of neuropsychological results is essential to benefit patient care. Errors in communication are a lead cause of medical errors; nevertheless, there remains a lack of consistency in how neuropsychological scores are communicated. A major limitation in the communication of neuropsychological results is the inconsistent use of qualitative descriptors for standardized test scores and the use of vague terminology. PubMed search from 1 Jan 2007 to 1 Aug 2016 to identify guidelines or consensus statements for the description and reporting of qualitative terms to communicate neuropsychological test scores was conducted. The review found the use of confusing and overlapping terms to describe various ranges of percentile standardized test scores. In response, we propose a simplified set of qualitative descriptors for normalized test scores (Q-Simple) as a means to reduce errors in communicating test results. The Q-Simple qualitative terms are: 'very superior', 'superior', 'high average', 'average', 'low average', 'borderline' and 'abnormal/impaired'. A case example illustrates the proposed Q-Simple qualitative classification system to communicate neuropsychological results for neurosurgical planning. The Q-Simple qualitative descriptor system is aimed as a means to improve and standardize communication of standardized neuropsychological test scores. Research are needed to further evaluate neuropsychological communication errors. Conveying the clinical implications of neuropsychological results in a manner that minimizes risk for communication errors is a quintessential component of evidence-based practice.

The quality of communication between spouses is widely assumed to affect their subsequent judgments of relationship satisfaction, yet this assumption is rarely tested against the alternative prediction that communication is merely a consequence of spouses’ prior levels of satisfaction. To evaluate these perspectives, newlywed couples’ positivity, negativity, and effectiveness were observed four times at 9-month intervals and these behaviors were examined in relation to corresponding self-reports of relationship satisfaction. Cross-sectionally, relatively satisfied couples engaged in more positive, less negative, and more effective communication. Longitudinally, reliable communication-to-satisfaction and satisfaction-to-communication associations were identified, yet neither pathway was particularly robust. These findings raise important doubts about theories and interventions that prioritize couple communication skills as the key predictor of relationship satisfaction, while raising new questions about other factors that might predict communication and satisfaction and that strengthen or moderate their association.

Lack of success in disaster recovery occurs for many reasons, with one predominant catalyst for catastrophic failure being flawed and inefficient communication systems. Increased occurrences of devastating environmental hazards and human-caused disasters will continue to promulgate throughout the United States and around the globe as a result of the continuous intensive urbanization forcing human population into more concentrated and interconnected societies. With the rapid evolutions in technology and the advent of Information and communication technology (ICT) interfaces such as Facebook, Twitter, Flickr, Myspace, and Smartphone technology, communication is no longer a unidirectional source of information traveling from the newsroom to the public. In the event of a disaster, time critical information can be exchanged to and from any person or organization simultaneously with the capability to receive feedback. A literature review of current information regarding the use of ICT as information infrastructures in disaster management during human-caused and natural disasters will be conducted. This article asserts that the integrated use of ICTs as multidirectional information sharing tools throughout the disaster cycle will increase a community's resiliency and supplement the capabilities of first responders and emergency management officials by providing real-time updates and information needed to assist and recover from a disaster.

Since the development of Centers for Disease Control's (CDC) guidelines for the management of suicide clusters, the use of electronic communication technologies has increased dramatically. To describe an adolescent suicide cluster that drew our attention to the possible role of online social networking and SMS text messaging as sources of contagion after a suicide and obstacles to recognition of a potential cluster. A public health approach involving a multidisciplinary community response was used to investigate a group of suicides of New Zealand adolescents thought to be a cluster. Difficulties in identifying and managing contagion posed by use of electronic communications were assessed. The probability of observing a time-space cluster such as this by chance alone was p = .009. The cases did not belong to a single school, rather several were linked by social networking sites, including sites created in memory of earlier suicide cases, as well as mobile telephones. These facilitated the rapid spread of information and rumor about the deaths throughout the community. They made the recognition and management of a possible cluster more difficult. Relevant community agencies should proactively develop a strategy to enable the identification and management of suicide contagion. Guidelines to assist communities in managing clusters should be updated to reflect the widespread use of communication technologies in modern society.

Experimental studies of applications of time-reversal acoustics to noncoherent underwater communications.

The most difficult problem in shallow underwater acoustic communications is considered to be the time-varying multipath propagation because it impacts negatively on data rates. At high data rates the intersymbol interference requires adaptive algorithms on the receiver side that lead to computationally intensive and complex signal processing. A novel technique called time-reversal acoustics (TRA) can environmentally adapt the acoustic propagation effects of a complex medium in order to focus energy at a particular target range and depth. Using TRA, the multipath structure is reduced because all the propagation paths add coherently at the intended target location. This property of time-reversal acoustics suggests a potential application in the field of noncoherent acoustic communications. This work presents results of a tank scale experiment using an algorithm for rapid transmission of binary data in a complex underwater environment with the TRA approach. A simple 15-symbol code provides an example of the simplicity and feasibility of the approach. Covert coding due to the inherent scrambling induced by the environment at points other than the intended receiver is also investigated. The experiments described suggest a high potential in data rate for the time-reversal approach in underwater acoustic communications while keeping the computational complexity low.

A pilot study was conducted to evaluate the effects of training teachers of children with autistic spectrum disorders (ASDs) in the use of the Picture Exchange Communication System (PECS). Thirty-four children with ASDs (29 boys and 5 girls) were selected from eight specialist schools. Teaching staff attended a 2 day PECS workshop and received six half-day visits from PECS consultants. Data on the children's use of PECS, spontaneous communication, and adaptive behaviour were collected before the study and at set times following the workshop. Significant, rapid increases were recorded in the level of PECS attained by the children, in their PECS vocabulary, and in their frequency of PECS use over time. Improvements in children's general level of communication were slower to occur. The majority of participants showed improvements in their ability to use PECS. The results are discussed in relation to the methodological and practical difficulties that arose during the project.

Determinants of public phobia about infectious diseases in South Korea: effect of health communication and gender difference.

2015-03-01

This study investigated the individual and social determinants of the public's phobia of infectious diseases in South Korea, where collective action was recently fueled by the public phobia over mad cow disease (bovine spongiform encephalopathy [BSE]). Gender-specific multivariate regression was used to compare the public perception of BSE and highly pathogenic avian influenza (HPAI). The analysis results differentiated between the determinants of the phobia for the 2 diseases, BSE and HPAI (N = 1002). As with HIV/AIDS and leprosy, the public fear of HPAI was expressed as a disease phobia that seeks to ensure the social exclusion of infection sources, whereas the fear of BSE was influenced by social and communication factors. Therefore, BSE, unlike previous HPAI, can be rapidly amplified amid the growing distrust in health communication, in which case the social determinants of disease phobia are associated with communicator trust, social values, and political attitude toward diseases rather than disease perception. © 2013 APJPH.

What communication strategies do AAC users want their communication partners to use? A preliminary study.

This study aims to investigate which communication strategies the people, who use augmentative and alternative communication (AAC), want their communication partners to use. We interviewed eight children using Talking Mats to examine the AAC users' own opinion. The results showed that they wanted their communication partners to take the initiative, to repair the breaks when communication breakdowns occurred, and to invest time in understanding what AAC users wanted to express. These results underlined the significant responsibility of communication partners and revealed the need for AAC user interventions to help them be active communicators. More research needs to emphasise AAC users' opinions about communication partner strategies to improve the communication processes for AAC-users and thereby promote social inclusion in natural environment. Implications for Rehabilitation Communication partner strategies can affect communication as well as personal development and life quality for augmentative and alternative communication (AAC) users. In AAC-users opinion, their communication partners should take the communicative initiative, repair the breaks when communication breakdowns occurred, and invest time in understanding what AAC-users want to express. There is a need to inform and educate communication partners, especially those unfamiliar to AAC users. Practical training sessions, clinician modelling and written materials may be helpful. A communication partner guide can be adapted to each individual AAC user who explains his or her communication preferences. Additionally, there is a need that the clinicians promote active rather than passive communication from AAC users, which requires that they have access to the necessary symbols.
