  1. Disaster and emergency communications prior to computers/Internet: a review.

    PubMed

    Farnham, John W

    2006-02-01

    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.

  4. Emergency Communications Console

    NASA Technical Reports Server (NTRS)

    1978-01-01

    NASA has applied its communications equipment expertise to development of a communications console that provides, in a compact package only slightly larger than an electric typewriter, all the emergency medical services communications functions needed for a regional hospital. A prototype unit, built by Johnson Space Center, has been installed in the Odessa (Texas) Medical Center Hospital. The hospital is the medical control center for the 17-county Permian Basin Emergency Medical System in west Texas. The console project originated in response to a request to NASA from the Texas governor's office, which sought a better way of providing emergency medical care in rural areas. Because ambulance travel time is frequently long in remote areas of west Texas, it is important that treatment begin at the scene of the emergency rather than at the hospital emergency room. A radio and telephone system linking ambulance emergency technicians and hospital staff makes this possible. But earlier equipment was complex, requiring specialized operators. A highly reliable system was needed to minimize breakdowns and provide controls of utmost simplicity, so that the system could be operated by physicians and nurses rather than by communications specialists. The resulting console has both radio and telephone sections. With the radio equipment, hospital personnel can communicate with ambulance drivers and paramedics, receive incoming electrocardiagrams, consult with other hospitals, page hospital staff and set up a radio-to-telephone "patch." The telephone portion of the system includes a hotline from the Permian Basin Emergency Medical Service's resource control center, an automatic dialer for contacting special care facilities in the Permian Basin network, a hospital intercom terminal and a means of relaying cardioscope displays and other data between hospitals. The integrated system also provides links with local disaster and civil defense organizations and with emergency "Dial 911

  5. Digital communication constraints in prior space missions

    NASA Technical Reports Server (NTRS)

    2004-01-01

    Digital communication is crucial for space endeavors. Jt transmits scientific and command data between earth stations and the spacecraft crew. It facilitates communications between astronauts, and provides live coverage during all phases of the mission. Digital communications provide ground stations and spacecraft crew precise data on the spacecraft position throughout the entire mission. Lessons learned from prior space missions are valuable for our new lunar and Mars missions set by our president s speech. These data will save our agency time and money, and set course our current developing technologies. Limitations on digital communications equipment pertaining mass, volume, data rate, frequency, antenna type and size, modulation, format, and power in the passed space missions are of particular interest. This activity is in support of ongoing communication architectural studies pertaining to robotic and human lunar exploration. The design capabilities and functionalities will depend on the space and power allocated for digital communication equipment. My contribution will be gathering these data, write a report, and present it to Communications Technology Division Staff. Antenna design is very carefully studied for each mission scenario. Currently, Phased array antennas are being developed for the lunar mission. Phased array antennas use little power, and electronically steer a beam instead of DC motors. There are 615 patches in the phased array antenna. These patches have to be modified to have high yield. 50 patches were created for testing. My part is to assist in the characterization of these patch antennas, and determine whether or not certain modifications to quartz micro-strip patch radiators result in a significant yield to warrant proceeding with repairs to the prototype 19 GHz ferroelectric reflect-array antenna. This work requires learning how to calibrate an automatic network, and mounting and testing antennas in coaxial fixtures. The purpose of this

  6. How do communication systems emerge?

    Communication involves a pair of behaviours—a signal and a response—that are functionally interdependent. Consequently, the emergence of communication involves a chicken-and-egg problem: if signals and responses are dependent on one another, then how does such a relationship emerge in the first place? The empirical literature suggests two solutions to this problem: ritualization and sensory manipulation; and instances of ritualization appear to be more common. However, it is not clear from a theoretical perspective why this should be the case, nor if there are any other routes to communication. Here, we develop an analytical model to examine how communication can emerge. We show that: (i) a state of non-interaction is evolutionarily stable, and so communication will not necessarily emerge even when it is in both parties' interest; (ii) the conditions for sensory manipulation are more stringent than for ritualization, and hence ritualization is likely to be more common; and (iii) communication can arise by a third route, when the intention to communicate can itself be communicated, but this may be limited to humans. More generally, our results demonstrate the utility of a functional approach to communication. PMID:22217724

  7. Rapidly deployable emergency communication system

    Gladden, Charles A.; Parelman, Martin H.

    1979-01-01

    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.

  10. Prior image constrained image reconstruction in emerging computed tomography applications

    NASA Astrophysics Data System (ADS)

    Brunner, Stephen T.

    Advances have been made in computed tomography (CT), especially in the past five years, by incorporating prior images into the image reconstruction process. In this dissertation, we investigate prior image constrained image reconstruction in three emerging CT applications: dual-energy CT, multi-energy photon-counting CT, and cone-beam CT in image-guided radiation therapy. First, we investigate the application of Prior Image Constrained Compressed Sensing (PICCS) in dual-energy CT, which has been called "one of the hottest research areas in CT." Phantom and animal studies are conducted using a state-of-the-art 64-slice GE Discovery 750 HD CT scanner to investigate the extent to which PICCS can enable radiation dose reduction in material density and virtual monochromatic imaging. Second, we extend the application of PICCS from dual-energy CT to multi-energy photon-counting CT, which has been called "one of the 12 topics in CT to be critical in the next decade." Numerical simulations are conducted to generate multiple energy bin images for a photon-counting CT acquisition and to investigate the extent to which PICCS can enable radiation dose efficiency improvement. Third, we investigate the performance of a newly proposed prior image constrained scatter correction technique to correct scatter-induced shading artifacts in cone-beam CT, which, when used in image-guided radiation therapy procedures, can assist in patient localization, and potentially, dose verification and adaptive radiation therapy. Phantom studies are conducted using a Varian 2100 EX system with an on-board imager to investigate the extent to which the prior image constrained scatter correction technique can mitigate scatter-induced shading artifacts in cone-beam CT. Results show that these prior image constrained image reconstruction techniques can reduce radiation dose in dual-energy CT by 50% in phantom and animal studies in material density and virtual monochromatic imaging, can lead to radiation

  13. Inflatable Antennas Support Emergency Communication

    NASA Technical Reports Server (NTRS)

    2010-01-01

    Glenn Research Center awarded Small Business Innovation Research (SBIR) contracts to ManTech SRS Technologies, of Newport Beach, California, to develop thin film inflatable antennas for space communication. With additional funding, SRS modified the concepts for ground-based inflatable antennas. GATR (Ground Antenna Transmit and Receive) Technologies, of Huntsville, Alabama, licensed the technology and refined it to become the world s first inflatable antenna certified by the Federal Communications Commission. Capable of providing Internet access, voice over Internet protocol, e-mail, video teleconferencing, broadcast television, and other high-bandwidth communications, the systems have provided communication during the wildfires in California, after Hurricane Katrina in Mississippi, and following the 2010 Haiti earthquake.

    The ability to communicate with spacecraft during emergencies is a vital service that NASA's Deep Space Network (DSN) provides to all deep space missions. Emergency communications is characterized by low data rates(typically is approximately10 bps) with the spacecraft using either a low-gain antenna (LGA, including omnidirectional antennas) or,in some cases, a medium-gain antenna (MGA). Because of the use of LGAs/MGAs for emergency communications, the transmitted power requirements both on the spacecraft andon the ground are substantially greater than those required for normal operations on the high-gain antenna (HGA) despite the lower data rates. In this paper, we look at currentand future emergency communications capabilities available to NASA's deep-space missions and discuss their limitations in the context of emergency mode operations requirements.These discussions include the use of the DSN 70-m diameter antennas, the use of the 34-m diameter antennas either alone or arrayed both for the uplink (Earth-to-spacecraft) and the downlink (spacecraft-to-Earth), upgrades to the ground transmitters, and spacecraft power requirements both with unitygain (0 dB) LGAs and with antennas with directivity (>0 dB gain, either LGA or MGA, depending on the gain). Also discussed are the requirements for forward-error-correctingcodes for both the uplink and the downlink. In additional, we introduce a methodology for proper selection of a directionalLGA/MGA for emergency communications.

    2008-03-01

    In the event of large-scale natural or manmade catastrophic events, access to reliable and enduring commercial communication systems is critical. Hurricane Katrina provided a recent example of the need to ensure communications during a national emergency. To ensure that communication demands are met during these critical times, Idaho National Laboratory (INL) under the guidance of United States Strategic Command has studied infrastructure issues, concerns, and vulnerabilities associated with an airborne wireless communications capability. Such a capability could provide emergency wireless communications until public/commercial nodes can be systematically restored. This report focuses on the airborne cellular restoration concept; analyzing basic infrastructure requirements; identifying related infrastructure issues, concerns, and vulnerabilities and offers recommended solutions.

    2016-01-01

    We study a neuro-inspired model that mimics a discussion (or information dissemination) process in a network of agents. During their interaction, agents redistribute activity and network weights, resulting in emergence of leader(s). The model is able to reproduce the basic scenarios of leadership known in nature and society: laissez-faire (irregular activity, weak leadership, sizable inter-follower interaction, autonomous sub-leaders); participative or democratic (strong leadership, but with feedback from followers); and autocratic (no feedback, one-way influence). Several pertinent aspects of these scenarios are found as well-e.g., hidden leadership (a hidden clique of agents driving the official autocratic leader), and successive leadership (two leaders influence followers by turns). We study how these scenarios emerge from inter-agent dynamics and how they depend on behavior rules of agents-in particular, on their inertia against state changes. PMID:27532484

  20. Evolutionary Conditions for the Emergence of Communication

    NASA Astrophysics Data System (ADS)

    Mitri, Sara; Floreano, Dario; Keller, Laurent

    Communication plays a central role in the biology of most organisms, particularly social species. Although the neurophysiological processes of signal production and perception are well understood, the conditions conducive to the evolution of reliable systems of communication remain largely unknown. This is a particularly challenging problem because efficient communication requires tight coevolution between the signal emitted and the response elicited. We conducted experimental evolution with robots that could produce visual signals to provide information on food location. We found that communication readily evolves when colonies consist of genetically similar individuals and when selection acts at the colony level. We identified several distinct communication systems that differed in their efficiency. Once a given system of communication was well established, it constrained the evolution of more efficient communication systems. Under individual selection, the ability to produce visual signals resulted in the evolution of deceptive communication strategies in colonies of unrelated robots and a concomitant decrease in colony performance. This study generates predictions about the evolutionary conditions conducive to the emergence of communication and provides guidelines for designing artificial evolutionary systems displaying spontaneous communication.

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

    Pidgeon, Nick; Harthorn, Barbara; Satterfield, Terre

    2011-11-01

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

    We present a novel direction based shortest path search algorithm to guide evacuees during an emergency. It uses opportunistic communications (oppcomms) with low-cost wearable mobile nodes that can exchange packets at close range of a few to some tens of meters without help of an infrastructure. The algorithm seeks the shortest path to exits which are safest with regard to a hazard, and is integrated into an autonomous Emergency Support System (ESS) to guide evacuees in a built environment. The algorithm proposed that ESSs are evaluated with the DBES (Distributed Building Evacuation Simulator) by simulating a shopping centre where fire is spreading. The results show that the directional path finding algorithm can offer significant improvements for the evacuees. PMID:25140633

    Emergency responses require the coordination of first responders to assess the condition of victims, stabilize their condition, and transport them to hospitals based on the severity of their injuries. WIISARD is a system designed to facilitate the collection of medical information and its reliable dissemination during emergency responses. A key challenge in WIISARD is to deliver data with high reliability as first responders move and operate in a dynamic radio environment fraught with frequent network disconnections. The initial WIISARD system employed a client-server architecture and an ad-hoc routing protocol was used to exchange data. The system had low reliability when deployed during emergency drills. In this paper, we identify the underlying causes of unreliability and propose a novel peer-to-peer architecture that in combination with a gossip-based communication protocol achieves high reliability. Empirical studies show that compared to the initial WIISARD system, the redesigned system improves reliability by as much as 37% while reducing the number of transmitted packets by 23%.

    It is frequently observed in emergent situation that important information does not reach to an right person or department in the organization because of the confusion after the emergency or in some case because of lack of knowledge on contact address. This phenomenon happens especially when different organizations are connected dynamically in emergency and it is very important to support communication in emergent situations. This paper deals with a communication support system considering dynamic organizational connection in emergency. The system is based on the communication model that considers human related factors such as “competence", “duty", “responsibility" and “knowledge" in organization. On the basis of the model, a communication support system to give contact address depending on the situation is designed and a prototype system with GUI is developed.

    Proper prefetching of relevant prior examinations from a picture archiving and communication system (PACS) archive, when a patient is scheduled for a new imaging study, and sending the historic images to the display station where the new examination is expected to be routed and subsequently read out, can greatly facilitate interpretation and review, as well as enhance radiology departmental workflow and PACS performance. In practice, it has proven extremely difficult to implement an automatic prefetch as successful as the experienced fileroom clerk. An algorithm based on defined metagroup categories for examination type mnemonics has been designed and implemented as one possible solution to the prefetch problem. The metagroups such as gastrointestinal (GI) tract, abdomen, chest, etc, can represent, in a small number of categories, the several hundreds of examination types performed by a typical radiology department. These metagroups can be defined in a table of examination mnemonics that maps a particular mnemonic to a metagroup or groups, and vice versa. This table is used to effect the prefetch rules of relevance. A given examination may relate to several prefetch categories, and preferences are easily configurable for a particular site. The prefetch algorithm metatable was implemented in database structured query language (SQL) using a many-to-many fetch category strategy. Algorithm performance was measured by analyzing the appropriateness of the priors fetched based on the examination type of the current study. Fetched relevant priors, missed relevant priors, fetched priors that were not relevant to the current examination, and priors not fetched that were not relevant were used to calculate sensitivity and specificity for the prefetch method. The time required for real-time requesting of priors not previously prefetched was also measured. The sensitivity of the prefetch algorithm was determined to be 98.3% and the specificity 100%.

    1994-09-01

    The CSEPP (Chemical Stockpile Emergency Preparedness Program) was created to improve emergency planning and response capabilities at the eight sites around the country that store chemical weapons. These weapons are scheduled to be destroyed in the near future. In preparation of the Draft Programmatic Environmental Impact Statement (DPEIS) for the Chemical Stockpile Disposal Program (CSDP), it was proposed that the Army mitigate accidents through an enhanced community emergency preparedness program at the eight storage sites. In 1986, the Army initiated the development of an Emergency Response Concept Plan (ERCP) for the CSDP, one of 12 technical support studies conducted during preparation of the Final Programmatic Environmental Impact Statement (FPEIS). The purpose of this document is to provide a fairly comprehensive source book on risk, risk management, risk communication research and recommended risk communication practices. It does not merely summarize each publication in the risk communication literature, but attempts to synthesize them along the lines of a set of organizing principles. Furthermore, it is not intended to duplicate other guidance manuals (such as Covello et al.`s manual on risk comparison). The source book was developed for the CSEPP in support of the training module on risk communications. Although the examples provided are specific to CSEPP, its use goes beyond that of CSEPP as the findings apply to a broad spectrum of risk communication topics. While the emphasis is on communication in emergency preparedness and response specific to the CSEPP, the materials cover other non-emergency communication settings. 329 refs.

  1. DETECTION OF THE HORIZONTAL DIVERGENT FLOW PRIOR TO THE SOLAR FLUX EMERGENCE

    SciTech Connect

    Toriumi, S.; Yokoyama, T.; Hayashi, K.

    2012-06-01

    It is widely accepted that solar active regions including sunspots are formed by the emerging magnetic flux from the deep convection zone. In previous numerical simulations, we found that the horizontal divergent flow (HDF) occurs before the flux emergence at the photospheric height. This paper reports the HDF detection prior to the flux emergence of NOAA AR 11081, which is located away from the disk center. We use SDO/HMI data to study the temporal changes of the Doppler and magnetic patterns from those of the reference quiet Sun. As a result, the HDF appearance is found to come before the flux emergence by about 100 minutes. Also, the horizontal speed of the HDF during this time gap is estimated to be 0.6-1.5 km s{sup -1}, up to 2.3 km s{sup -1}. The HDF is caused by the plasma escaping horizontally from the rising magnetic flux. And the interval between the HDF and the flux emergence may reflect the latency during which the magnetic flux beneath the solar surface is waiting for the instability onset to the further emergence. Moreover, SMART H{alpha} images show that the chromospheric plages appear about 14 minutes later, located cospatial with the photospheric pores. This indicates that the plages are caused by plasma flowing down along the magnetic fields that connect the pores at their footpoints. One important result of observing the HDF may be the possibility of predicting the sunspot appearances that occur in several hours.

  2. Enabling Communication in Emergency Response Environments

    Effective communication among first responders during response to natural and human-made large-scale catastrophes has increased tremendously during the last decade. However, most efforts to achieve a higher degree of effectiveness in communication lack synergy between the environment and the technology involved to support first responders operations. This article presents a natural and intuitive interface to support Stigmergy; or communication through the environment, based on intuitively marking and retrieving information from the environment with a pointer. A prototype of the system was built and tested in the field, however the pointing activity revealed challenges regarding accuracy due to limitations of the sensors used. The results obtained from these field tests were the basis for this research effort and will have the potential to enable communication through the environment for first responders operating in highly dynamical and inhospitable disaster relief environments.

    How can we understand each other during communicative interactions? An influential suggestion holds that communicators are primed by each other's behaviors, with associative mechanisms automatically coordinating the production of communicative signals and the comprehension of their meanings. An alternative suggestion posits that mutual understanding requires shared conceptualizations of a signal's use, i.e., "conceptual pacts" that are abstracted away from specific experiences. Both accounts predict coherent neural dynamics across communicators, aligned either to the occurrence of a signal or to the dynamics of conceptual pacts. Using coherence spectral-density analysis of cerebral activity simultaneously measured in pairs of communicators, this study shows that establishing mutual understanding of novel signals synchronizes cerebral dynamics across communicators' right temporal lobes. This interpersonal cerebral coherence occurred only within pairs with a shared communicative history, and at temporal scales independent from signals' occurrences. These findings favor the notion that meaning emerges from shared conceptualizations of a signal's use. PMID:25489093

    2010-06-15

    Any bipartite nonlocal unitary operation can be carried out by teleporting a quantum state from one party to the other, performing the unitary gate locally, and teleporting a state back again. This paper investigates unitaries which can be carried out using less prior entanglement and classical communication than are needed for teleportation. Large families of such unitaries are constructed using (projective) representations of finite groups. Among the tools employed are: a diagrammatic approach for representing entangled states, a theorem on the necessary absence of information at certain times and locations, and a representation of bipartite unitaries based on a group Fourier transform.

    Communication theory and techniques, aided by the electronic revolution, provide new opportunities and challenges for the effective transfer of laboratory, epidemiologic, surveillance, and other public health data to the public who funds them. We review the applicability of communication theory, particularly the audience-source-message-channel meta-model, to emerging infectious disease issues. Emergence of new infectious organisms, microbial resistance to therapeutic drugs, and increased emphasis on prevention have expanded the role of communication as a vital component of public health practice. In the absence of cure, as in AIDS and many other public health problems, an effectively crafted and disseminated prevention message is the key control measure. Applying communication theory to disease prevention messages can increase the effectiveness of the messages and improve public health. PMID:10905966

    Introduction Respiratory failure is a common problem in emergency medicine (EM) and critical care medicine (CCM). However, little is known about the resuscitation of critically ill patients prior to emergency endotracheal intubation (EETI). Our aim was to describe the resuscitation practices of EM and CCM physicians prior to EETI. Methods A cross-sectional survey was developed and tested for content validity and retest reliability by members of the Canadian Critical Care Trials Group. The questionnaire was distributed to all EM and CCM physician members of three national organizations. Using three clinical scenarios (trauma, pneumonia, congestive heart failure), we assessed physician preferences for use and types of fluid and vasopressor medication in pre-EETI resuscitation of critically ill patients. Results In total, 1,758 physicians were surveyed (response rate 50.2%, 882/1,758). Overall, physicians would perform pre-EETI resuscitation using either fluids or vasopressors in 54% (1,193/2,203) of cases. Most physicians would “always/often” administer intravenous fluid pre-EETI in the three clinical scenarios (81%, 1,484/1,830). Crystalloids were the most common fluid physicians would “always/often” administer in congestive heart failure (EM 43%; CCM 44%), pneumonia (EM 97%; CCM 95%) and trauma (EM 96%; CCM 96%). Pre-EETI resuscitation using vasopressors was uncommon (4.9%). Training in CCM was associated with performing pre-EETI resuscitation (odds ratio, 2.20; 95% CI, [1.44–3.36], p<0.001). Conclusion Pre-EETI resuscitation is common among Canadian EM and CCM physicians. Most physicians use crystalloids pre-EETI as a resuscitation fluid, while few would give vasopressors. Physicians with CCM training were more likely to perform pre-EETI resuscitation. PMID:27625717

  13. Network analysis of team communication in a busy emergency department

    2013-01-01

    Background The Emergency Department (ED) is consistently described as a high-risk environment for patients and clinicians that demands colleagues quickly work together as a cohesive group. Communication between nurses, physicians, and other ED clinicians is complex and difficult to track. A clear understanding of communications in the ED is lacking, which has a potentially negative impact on the design and effectiveness of interventions to improve communications. We sought to use Social Network Analysis (SNA) to characterize communication between clinicians in the ED. Methods Over three-months, we surveyed to solicit the communication relationships between clinicians at one urban academic ED across all shifts. We abstracted survey responses into matrices, calculated three standard SNA measures (network density, network centralization, and in-degree centrality), and presented findings stratified by night/day shift and over time. Results We received surveys from 82% of eligible participants and identified wide variation in the magnitude of communication cohesion (density) and concentration of communication between clinicians (centralization) by day/night shift and over time. We also identified variation in in-degree centrality (a measure of power/influence) by day/night shift and over time. Conclusions We show that SNA measurement techniques provide a comprehensive view of ED communication patterns. Our use of SNA revealed that frequency of communication as a measure of interdependencies between ED clinicians varies by day/night shift and over time. PMID:23521890

    The application of an integrated satellite/terrestrial emergency response communications system in disaster relief operations is discussed. Large area coverage communications capability, full-time availability, a high degree of mobility, plus reliability, are pointed out as criteria for an effective emergency communications system. Response time is seen as a major factor determining the possible survival and/or protection of property. These criteria, can not be met by existing communications systems and complete blackouts were experienced during the past decades caused by either interruption or destruction of existing power lines, and overload or inadequacy of remaining lines. Several emergency cases, caused by either hurricanes, tornados, or floods, during which communication via satellite was instrumental to inform rescue and relief teams, are described in detail. Seismic Risk Maps and charts of Major Tectonic Plates Earthquake Epicenters are given, and it is noted that, 35 percent of the U.S. population is living in critical areas. National and international agreements for the implementation of a satellite-aided global Search and Rescue Program is mentioned. Technological and economic breakthroughs are still needed in large multibeam antennas, switching circuits, and low cost mobile ground terminals. A pending plan of NASA to initiate a multiservice program in 1982/83, with a Land Mobile Satellite capability operating in the 806 - 890 MHz band as a major element, may help to accelerate the needed breakthroughs.

    Most theories of persuasion predict that limited ability and motivation to think about communications should increase the impact of source credibility on persuasion. Furthermore, this effect is assumed to occur, regardless of whether or not the recipients have prior attitudes. In this study, the effects of source credibility, ability, and motivation (knowledge, message repetition, relevance) on persuasion were examined meta-analytically across both attitude formation and change conditions. Findings revealed that the Source Credibility × Ability/Motivation interaction emerged only when participants lacked prior attitudes and were unable to form a new attitude based on the message content. In such settings, the effects of source credibility decayed rapidly. The implications of these findings for applied communication campaigns are discussed. PMID:21625405

    One of the greater challenges the Army faces is effectively dealing with the concerns of the public, local officials and the news media on the disposal of aging chemical agents. This paper describes the method developed for the Chemical Stockpile Emergency Preparedness Program (CSEPP). The purpose was to provide a fairly comprehensive document on risk communication research and recommended practices as they related to the CSEPP. Using the communications perspective suggested by Covello and colleagues, the existing practices of communicating risk information about chemical weapons and the associated efforts in emergency planning, storage and eventual disposal are described. Risk communication problems specific to the CSEPP are then examined and described via scenarios. A framework is developed that distinguishes between the major components of risk communication, flow and intent. Within this framework, the research and recommendations are summarized as to direction of flow -- dialogue, or two-way interaction, versus monologue, or one-way communication -- and that of intent -- exchange versus persuasion. The findings and recommendations are synthesized and related to risk events for the CSEPP as posited in the scenarios.

    Children suffer most from today's increasing precariousness. In France, access to care is available for all children through various structures and existing measures. The support for foreign children is overseen by specific legislation often unfamiliar to caregivers. Pediatric emergencies, their location, organization, actors, and patient flow are a particular environment that is not always suitable to communication and may lead to situations of abuse. Communication should not be forgotten because of the urgency of the situation. The place of the child in the dialogue is often forgotten. Considering the triangular relationship, listening to the child and involving the parents in care are the basis for a good therapeutic alliance. Privacy and medical confidentiality in pediatric emergencies are governed by law. However, changes in treatments and medical practices along with the variety of actors involved imply both individual and collective limitations, to the detriment of medical confidentiality.

    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 emergency department visit for a patient with serious illness represents a sentinel event, signalling a change in the illness trajectory. By better understanding patient and family wishes, emergency physicians can reinforce advance care plans and ensure the hospital care provided matches the patient's values. Despite their importance in care at the end of life, emergency physicians have received little training on how to talk to seriously ill patients and their families about goals of care. To expand communication skills training to emergency medicine, we developed a programme to give emergency medicine physicians the ability to empathically deliver serious news and to talk about goals of care. We have built on lessons from prior studies to design an intervention employing the most effective pedagogical techniques, including the use of simulated patients/families, role-playing and small group learning with constructive feedback from master clinicians. Here, we describe our evidence-based communication skills training course EM Talk using simulation, reflective feedback and deliberate practice. PMID:26762163

    Three experiments explore several factors which influence information transmission when warning messages are passed from person to person. In Experiment 1, messages were passed down chains of participants using five different modes of communication. Written communication channels resulted in more accurate message transmission than verbal. In addition, some elements of the message endured further down the chain than others. Experiment 2 largely replicated these effects and also demonstrated that simple repetition of a message eliminated differences between written and spoken communication. In a final field experiment, chains of participants passed information however they wanted to, with the proviso that half of the chains could not use telephones. Here, the lack of ability to use a telephone did not affect accuracy, but did slow down the speed of transmission from the recipient of the message to the last person in the chain. Implications of the findings for crisis and emergency risk communication are discussed. PMID:25683552

    Isotropic broadband probes or spectrum analyzers (SAs) may be used for the measurement of rapidly varying electromagnetic fields generated by emerging wireless communication systems. In this paper this problematic is investigated by comparing the responses measured by two different isotropic broadband probes typically used to perform electric field (E-field) evaluations. The broadband probes are submitted to signals with variable duty cycles (DC) and crest factors (CF) either with or without Orthogonal Frequency Division Multiplexing (OFDM) modulation but with the same root-mean-square (RMS) power. The two probes do not provide accurate enough results for deterministic signals such as Worldwide Interoperability for Microwave Access (WIMAX) or Long Term Evolution (LTE) as well as for non-deterministic signals such as Wireless Fidelity (WiFi). The legacy measurement protocols should be adapted to cope for the emerging wireless communication technologies based on the OFDM modulation scheme. This is not easily achieved except when the statistics of the RF emission are well known. In this case the measurement errors are shown to be systematic and a correction factor or calibration can be applied to obtain a good approximation of the total RMS power.

    An objective of NASA's Computing, Information, and Communications Technology program is to support the development of technologies that could potentially lower the cost of the Earth science and space exploration missions, and result in greater scientific returns. NASA-supported photonic activities which will impact space communications will be described. The objective of the RF microphotonic research is to develop a Ka-band receiver that will enable the microwaves detected by an antenna to modulate a 1.55- micron optical carrier. A key element is the high-Q, microphotonic modulator that employs a lithium niobate microdisk. The technical approach could lead to new receivers that utilize ultra-fast, photonic signal processing techniques, and are low cost, compact, low weight and power efficient. The progress in the liquid crystal (LC) beam steering research will also be reported. The predicted benefits of an LC-based device on board a spacecraft include non-mechanical, submicroradian laser-beam pointing, milliradian scanning ranges, and wave-front correction. The potential applications of these emerging technologies to the various NASA missions will be presented.

  12. Optimizing local protocols for implementing bipartite nonlocal unitary gates using prior entanglement and classical communication

    SciTech Connect

    Cohen, Scott M.

    2010-06-15

    We present a method of optimizing recently designed protocols for implementing an arbitrary nonlocal unitary gate acting on a bipartite system. These protocols use only local operations and classical communication with the assistance of entanglement, and they are deterministic while also being 'one-shot', in that they use only one copy of an entangled resource state. The optimization minimizes the amount of entanglement needed, and also the amount of classical communication, and it is often the case that less of each of these resources is needed than with an alternative protocol using two-way teleportation.

    Two cases of febrile respiratory illness associated with untypeable influenza A virus were identified in Southern California in March 2009. One was initially detected as influenza virus using an experimental diagnostic device in a clinical trial, while the other was detected at a local reference lab using a diagnostic PCR assay. In both cases, analyses yielded negative results for strain-specific tests targeting circulating strains of influenza A virus (seasonal H1 and H3). These two samples became the first reported cases of the pandemic 2009/H1N1 influenza virus. The first reportable characterization was made from the second collected specimen on 15 April 2009 at the Centers for Disease Control and Prevention central lab using traditional culture and sequencing methods. The novel nature of the strain and its apparent zoonotic origins were initially characterized using the first collected specimen at the Naval Health Research Center in San Diego, CA, on 13 April using an experimental molecular analysis tool, PCR electro-spray ionization-mass spectrometry (PCR/ESI-MS), designed to amplify PCR products from any strain of influenza virus and to generate informative (phylogenetic) strain identifications through mass spectrometry of PCR amplicons. The ability of this high-throughput tool to correctly identify both well-characterized and novel influenza strains offers the possibility to integrate surveillance for emerging strains with on-site rapid diagnosis used for patient management, shortening the times between the emergence of new strains, their detection and identification, and appropriate public health response activities. Here we describe the initial characterization of the pandemic 2009/H1N1 influenza strain and discuss the possible roles of diagnostic tools with discovery potential. PMID:20861338

    Patient-centered emergency diagnostic imaging relies on efficient communication and multispecialty care coordination to ensure optimal imaging utilization. The construct of the emergency diagnostic imaging care coordination cycle with three main phases (pretest, test, and posttest) provides a useful framework to evaluate care coordination in patient-centered emergency diagnostic imaging. This article summarizes findings reached during the patient-centered outcomes session of the 2015 Academic Emergency Medicine consensus conference "Diagnostic Imaging in the Emergency Department: A Research Agenda to Optimize Utilization." The primary objective was to develop a research agenda focused on 1) defining component parts of the emergency diagnostic imaging care coordination process, 2) identifying gaps in communication that affect emergency diagnostic imaging, and 3) defining optimal methods of communication and multidisciplinary care coordination that ensure patient-centered emergency diagnostic imaging. Prioritized research questions provided the framework to define a research agenda for multidisciplinary care coordination in emergency diagnostic imaging. PMID:26575785

    Background The literature describing the health services individuals receive prior to and following self-directed violence is limited. Objectives This study examines services received for the six months preceding admission to an urban county medical center emergency department for self-directed violence. We predicted that individuals with at least one prior act of self-directed violence in the past six months would have received more services than those for whom the index admission was their only recent act. Method Participants were recruited from emergency department admissions during shifts selected to maximize representativeness. Participants (n=202) were interviewed using the Suicide Attempt Self-Injury Interview, Suicide Attempt Self-Injury Count, Treatment History Interview, MINI, Brief Symptom Index, and SF-12. Results The majority of index acts of self-directed violence (79%) were suicide attempts. The participants were characterized by low socio-economic status, substantial symptomatology, low physical and mental health functioning, and multiple psychiatric diagnoses. In the preceding six months, 34% were admitted to a hospital and 56% received crisis services (including 44% in the ED). While three quarters (76%) had seen an outpatient medical provider and most (70%) received psychotropic medications, less than half of the sample received psychiatric services (40%) or outpatient psychosocial treatment (48%). As predicted, utilization for most types of usual care was higher for those engaging in self-directed violence in the six months preceding the index admission. Conclusions Individuals admitted to this emergency department for self-directed violence received inadequate outpatient psychosocial and psychiatric services despite severe illness and disability.

    Objective Alternatives to prospective informed consent to enable children with life-threatening conditions to be entered into trials of emergency treatments are needed. Across Europe, a process called deferred consent has been developed as an alternative. Little is known about the views and experiences of those with first-hand experience of this controversial consent process. To inform how consent is sought for future paediatric critical care trials, we explored the views and experiences of parents and practitioners involved in the CATheter infections in CHildren (CATCH) trial, which allowed for deferred consent in certain circumstances. Design Mixed method survey, interview and focus group study. Participants 275 parents completed a questionnaire; 20 families participated in an interview (18 mothers, 5 fathers). 17 CATCH practitioners participated in one of four focus groups (10 nurses, 3 doctors and 4 clinical trial unit staff). Setting 12 UK children's hospitals. Results Some parents were momentarily shocked or angered to discover that their child had or could have been entered into CATCH without their prior consent. Although these feelings resolved after the reasons why consent needed to be deferred were explained and that the CATCH interventions were already used in clinical care. Prior to seeking deferred consent for the first few times, CATCH practitioners were apprehensive, although their feelings abated with experience of talking to parents about CATCH. Parents reported that their decisions about their child's participation in the trial had been voluntary. However, mistiming the deferred consent discussion had caused distress for some. Practitioners and parents supported the use of deferred consent in CATCH and in future trials of interventions already used in clinical care. Conclusions Our study provides evidence to support the use of deferred consent in paediatric emergency medicine; it also indicates the crucial importance of practitioner communication

    2012-01-01

    Background: The aim of the study was a recommendation and establishment the concept of the appropriate communication between public health, other competent services and population in emergency as the corner stone which guarantee that all goals which are important for community life will be achieved. Methods: We used methodology appropriate for social science: analyses of documents, historical approach and comparative analysis. Results: The finding shows the urgent need for accepting of crises and emergency risk communication principles, or some similar concepts, in Serbia, and implementing effective two way communication especially in multiethnic region. The pragmatic value of the paper lays in information about the recent improvement of health workforce and emergency services in emergencies using new concept of communication and as source of numerous useful documents published in USA and few recent Serbian examples. Conclusion: Health workforce has significant role in the process of protection of population in emergencies. Policy makers should work on finding a way to improve their coordination and communication, creating new academic programs, providing of adequate training, and financial means in order to give them different role in society and provide visibility. From other side health workforce should build back to the citizen trust in what they are doing for society welfare using all their skills and abilities. PMID:23308348

    Zipf's law seems to be ubiquitous in human languages and appears to be a universal property of complex communicating systems. Following the early proposal made by Zipf concerning the presence of a tension between the efforts of speaker and hearer in a communication system, we introduce evolution by means of a variational approach to the problem based on Kullback's Minimum Discrimination of Information Principle. Therefore, using a formalism fully embedded in the framework of information theory, we demonstrate that Zipf's law is the only expected outcome of an evolving communicative system under a rigorous definition of the communicative tension described by Zipf.

  2. Emergence of Linguistic Communication: Studies on Grey Parrots

    NASA Astrophysics Data System (ADS)

    Pepperberg, Irene M.

    Most studies on the evolution of communication systems concentrate on the primate lineage, ignoring the concept of parallel lines of evolution. Although phylogenetically remote from humans, some birds—particularly Grey parrots—share many cognitive and communicative abilities with humans. On certain tasks, they demonstrate processing abilities comparable to 5-6 year-old humans; they learn very simple vocal syntactic patterns and referential elements of human communication, but only through social interaction and in a manner that proceeds in ways similar to those of humans. Given this knowledge of vocal learning in birds, of the effects of social interaction on such learning, and of birds' complex cognitive abilities, we should not ignore the avian line if we wish to determine the evolutionary pressures that purportedly affected the evolution of complex communication systems—particularly vocal systems—and develop theories and models that can be tested.

    In the last several years, disasters-both manmade and natural-have taken their toll on college campuses. Extant research shows that college campuses have greatly increased their emergency management efforts. One area in which colleges and universities have made strides is emergency management communication. There has been some research examining emergency management communication across campuses, but there is still much to learn. This research fills a gap in this area by investigating the use of university Web sites to disseminate emergency management information to the university stakeholders. Data were gathered in 2007 and 2014 from the Web sites of public, 4-year universities in Indiana. The results show that universities are using the Internet to communicate emergency management information to their stakeholders. Among the most common categories of information available on the Web sites are links to other agencies, university response information, and threat levels. Implications for future research are discussed. PMID:27575641

    2015-01-01

    Background: A highly important factor in enhancing quality of patient care and job satisfaction of health care staff is inter-professional communication. Due to the critical nature of the work environment, the large number of staff and units, and complexity of professional tasks and interventions, inter-professional communication in an emergency department is particularly and exceptionally important. Despite its importance, inter-professional communication in emergency department seems unfavorable. Thus, this study was designed to explain barriers to inter-professional communication in an emergency department. Methodology & Methods: This was a qualitative study with content analysis approach, based on interviews conducted with 26 participants selected purposively, with diversity of occupation, position, age, gender, history, and place of work. Interviews were in-depth and semi-structured, and data were analyzed using the inductive content analysis approach. Results: In total, 251 initial codes were extracted from 30 interviews (some of the participants re-interviewed) and in the reducing trend of final results, 5 categories were extracted including overcrowded emergency, stressful emergency environment, not discerning emergency conditions, ineffective management, and inefficient communication channels. Tumultuous atmosphere (physical, mental) was the common theme between categories, and was decided to be the main barrier to effective inter-professional communication. Conclusion: Tumultuous atmosphere (physical-mental) was found to be the most important barrier to inter-professional communication. This study provided a better understanding of these barriers in emergency department, often neglected in most studies. It is held that by reducing environmental turmoil (physical-mental), inter-professional communication can be improved, thereby improving patient care outcomes and personnel job satisfaction.

  10. Communication and interpretation of emotional distress within the friendships of young Irish men prior to suicide: a qualitative study.

    PubMed

    Sweeney, Lorna; Owens, Christabel; Malone, Kevin

    2015-03-01

    The potential for young men in crisis to be supported by their lay networks is an important issue for suicide prevention, due to the under-utilisation of healthcare services by this population. Central to the provision of lay support is the capability of social networks to recognise and respond effectively to young men's psychological distress and suicide risk. The aim of this qualitative study was to explore young men's narratives of peer suicide, in order to identify how they interpreted and responded to behavioural changes and indications of distress from their friend before suicide. In-depth qualitative interviews were conducted during 2009/10 with 15 Irish males (aged 19-30 years) who had experienced the death by suicide of a male friend in the preceding 5 years. The data were analysed using a thematic approach. Through the analysis of the participants' stories and experiences, we identified several features of young male friendships and social interactions that could be addressed to strengthen the support available to young men in crisis. These included the reluctance of young men to discuss emotional or personal issues within male friendships; the tendency to reveal worries and emotion only within the context of alcohol consumption; the tendency of friends to respond in a dismissive or disapproving way to communication of suicidal thoughts; the difficulty of knowing how to interpret a friend's inconsistent or ambiguous behaviour prior to suicide; and beliefs about the sort of person who takes their own life. Community-based suicide prevention initiatives must enhance the potential of young male social networks to support young men in crisis, through specific provisions for developing openness in communication and responsiveness, and improved education about suicide risk.

    2006-07-01

    Cost reduction pressure on companies and increasing regulatory and legislative demand together with rapid technological progress in space-based communication and navigation are opening up new and exciting commercial opportunities. In this framework, a novel service for maritime applications is presented using a two-way messaging system and the global navigation satellite system (GNSS). The system implements an end-to-end solution for asset tracking and fleet management, positioning and tracing, messaging and security for all types of sea-going vessels. The service applies a vessel-based terminal hosting a GNSS receiver which transmits the navigation status together with messages to a Service Center with a flexible return-link capability. A hybrid space segment is considered comprising the Inmarsat constellation of geostationary communications satellites augmented by two highly inclined low earth orbit satellites for truly global services. Services will be offered to commercial enterprises such as fishing companies as well as public entities such as National Coast Guards. A detailed market analysis has been performed to assess these markets and to determine their penetration. Commercial viability has been proven for business models purely based on Inmarsat and a hybrid space segment using Inmarsat and dedicated micro-satellites. Both cases represent viable businesses in the range of MEUR 100 p.a. Although tailored to a specific market, the approach can be extended to other commercial opportunities requiring space-based communication-navigation services.

    We study the impact of prior individual training during group emergency evacuation using mice that escape from an enclosed water pool to a dry platform via any of two possible exits. Experimenting with mice avoids serious ethical and legal issues that arise when dealing with unwitting human participants while minimizing concerns regarding the reliability of results obtained from simulated experiments using 'actors'. First, mice were trained separately and their individual escape times measured over several trials. Mice learned quickly to swim towards an exit-they achieved their fastest escape times within the first four trials. The trained mice were then placed together in the pool and allowed to escape. No two mice were permitted in the pool beforehand and only one could pass through an exit opening at any given time. At first trial, groups of trained mice escaped seven and five times faster than their corresponding control groups of untrained mice at pool occupancy rate ρ of 11.9% and 4%, respectively. Faster evacuation happened because trained mice: (a) had better recognition of the available pool space and took shorter escape routes to an exit, (b) were less likely to form arches that blocked an exit opening, and (c) utilized the two exits efficiently without preference. Trained groups achieved continuous egress without an apparent leader-coordinator (self-organized queuing)-a collective behavior not experienced during individual training. Queuing was unobserved in untrained groups where mice were prone to wall seeking, aimless swimming and/or blind copying that produced circuitous escape routes, biased exit use and clogging. The experiments also reveal that faster and less costly group training at ρ = 4%, yielded an average individual escape time that is comparable with individualized training. However, group training in a more crowded pool (ρ = 11.9%) produced a longer average individual escape time. PMID:25693170

    The management of medical emergency, in particular cardiac emergency, requests prompt intervention and the possibility to communicate in real time from the emergency area / ambulance to the hospital as much diagnostic information as possible about the patient. This would enable a prompt emergency diagnosis and operation and the possibility to prepare the appropriate actions in the suitable hospital department. To address this scenario, the CONCERTO European project proposed a wireless communication system based on a novel cross-layer architecture, including the integration of building blocks for medical media content fusion, delivery and access. This paper describes the proposed system architecture, outlining the developed components and mechanisms, and the evaluation of the proposed system, carried out in a hospital with the support of medical staff. The technical results and the feedback received highlight the impact of the CONCERTO approach in the healthcare domain, in particular in enabling a prompt and reliable diagnosis in challenging medical emergency scenarios.

  20. Software-Defined Ultra-wideband Radio Communications: A New RF Technology for Emergency Response Applications

    SciTech Connect

    Nekoogar, F; Dowla, F

    2009-10-19

    Reliable wireless communication links for local-area (short-range) and regional (long-range) reach capabilities are crucial for emergency response to disasters. Lack of a dependable communication system can result in disruptions in the situational awareness between the local responders in the field and the emergency command and control centers. To date, all wireless communications systems such as cell phones and walkie-talkies use narrowband radio frequency (RF) signaling for data communication. However, the hostile radio propagation environment caused by collapsed structures and rubble in various disaster sites results in significant degradation and attenuation of narrowband RF signals, which ends up in frequent communication breakdowns. To address the challenges of reliable radio communication in disaster fields, we propose an approach to use ultra-wideband (UWB) or wideband RF waveforms for implementation on Software Defined Radio (SDR) platforms. Ultra-wideband communications has been proven by many research groups to be effective in addressing many of the limitations faced by conventional narrowband radio technologies. In addition, LLNL's radio and wireless team have shown significant success in field deployment of various UWB communications system for harsh environments based on LLNL's patented UWB modulation and equalization techniques. Furthermore, using software defined radio platform for UWB communications offers a great deal of flexibility in operational parameters and helps the radio system to dynamically adapt itself to its environment for optimal performance.

  1. Emerging applications of high temperature superconductors for space communications

    NASA Technical Reports Server (NTRS)

    Heinen, Vernon O.; Bhasin, Kul B.; Long, Kenwyn J.

    1990-01-01

    Proposed space missions require longevity of communications system components, high input power levels, and high speed digital logic devices. The complexity of these missions calls for a high data bandwidth capacity. Incorporation of high temperature superconducting (HTS) thin films into some of these communications system components may provide a means of meeting these requirements. Space applications of superconducting technology has previously been limited by the requirement of cooling to near liquid helium temperatures. Development of HTS materials with transition temperatures above 77 K along with the natural cooling ability of space suggest that space applications may lead the way in the applications of high temperature superconductivity. In order for HTS materials to be incorporated into microwave and millimeter wave devices, the material properties such as electrical conductivity, current density, surface resistivity and others as a function of temperature and frequency must be well characterized and understood. The millimeter wave conductivity and surface resistivity were well characterized, and at 77 K are better than copper. Basic microwave circuits such as ring resonators were used to determine transmission line losses. Higher Q values than those of gold resonator circuits were observed below the transition temperature. Several key HTS circuits including filters, oscillators, phase shifters and phased array antenna feeds are feasible in the near future. For technology to improve further, good quality, large area films must be reproducibly grown on low dielectric constant, low loss microwave substrates.

    Recent natural and human-caused disasters have awakened public health officials to the importance of emergency preparedness. Guided by health behavior and media effects theories, the analysis of a statewide survey in Georgia reveals that self-efficacy, subjective norm, and emergency news exposure are positively associated with the respondents' possession of emergency items and their stages of emergency preparedness. Practical implications suggest less focus on demographics as the sole predictor of emergency preparedness and more comprehensive measures of preparedness, including both a person's cognitive stage of preparedness and checklists of emergency items on hand. We highlight the utility of theory-based approaches for understanding and predicting public emergency preparedness as a way to enable more effective health and risk communication. PMID:20574880

    The paper discusses some of the current and potential markets for satellite data communications as projected by the Public Service Satellite Consortium (PSSC). Organizations in the public service sector are divided into three categories, depending on their expected benefits and organizational changes due to increased satellite telecommunications use: A - modest institutional adjustments are necessary and significant productivity gains are likely; B - institutional requirements picture is promising, but more information is needed to assess benefits and risk; and C - major institutional adjustments are needed, risks are high but possible benefits are high. These criteria are applied to the U.S. health care system, continuing education, equipment maintenance, libraries, environmental monitoring, and other potential markets. The potential revenues are seen to be significant, but what is needed is a cooperative effort by common carriers and major public service institutions to aggregate the market.

    Twenty-first century demand for radio spectrum continues to increase with the explosive growth of wireless devices, but authorities reserve slices of the spectrum for licensed Amateur Radio operators, recognizing their value to the public, particularly with respect to providing emergency communications. Blood banking and transfusion medicine are among the specialties that should also recognize the value of Amateur Radio as an emergency communications medium, because blood collection, testing, processing, storage, and transfusion are life-saving activities that in modern times can be separated by considerable distance.

    2013-01-01

    During a public health crisis, public health agencies engage in a variety of public communication efforts to inform the population, encourage the adoption of preventive behaviors, and limit the impact of adverse events. Given the importance of communication to the public in public health emergency preparedness, it is critical to examine the extent to which this field of study has received attention from the scientific community. We conducted a systematic literature review to describe current research in the area of communication to the public in public health emergency preparedness, focusing on the association between sociodemographic and behavioral factors and communication as well as preparedness outcomes. Articles were searched in PubMed and Embase and reviewed by 2 independent reviewers. A total of 131 articles were included for final review. Fifty-three percent of the articles were empirical, of which 74% were population-based studies, and 26% used information environment analysis techniques. None had an experimental study design. Population-based studies were rarely supported by theoretical models and mostly relied on a cross-sectional study design. Consistent results were reported on the association between population socioeconomic factors and public health emergency preparedness communication and preparedness outcomes. Our findings show the need for empirical research to determine what type of communication messages can be effective in achieving preparedness outcomes across various population groups. They suggest that a real-time analysis of the information environment is valuable in knowing what is being communicated to the public and could be used for course correction of public health messages during a crisis.

    2014-01-01

    Background Toll free mobile telephone intervention to support mothers in pregnancy and delivery period was tested in one sub district of Bangladesh. Qualitative research was conducted to measure the changes of mobile phone use in increasing communication for maternal and neonatal complications. Methods In-depth interviews were conducted among twelve Community Skilled Birth Attendants and fourteen mothers along with their husbands prior to intervention. At intervention end, six Community Skilled Birth Attendants were purposively selected for in-depth interview. Semi structured interviews were conducted among all 27 Community Skilled Birth Attendants engaged in the intervention. One Focus Group Discussion was conducted with 10 recently delivered mothers. Thematic analysis and triangulation of different responses were conducted. Results Prior to intervention, Community Skilled Birth Attendants reported that mobile communication was not a norm. It was also revealed that poor mothers had poor accessibility to mobile services. Mothers, who communicated through mobile phone with providers noted irritability from Community Skilled Birth Attendants and sometimes found phones switched off. At the end of the project, 85% of mothers who had attended orientation sessions of the intervention communicated with Community Skilled Birth Attendants through mobile phones during maternal health complications. Once a complication is reported or anticipated over phone, Community Skilled Birth Attendants either made a prompt visit to mothers or advised for direct referral. More than 80% Community Skilled Birth Attendants communicated with Solution Linked Group for guidance on maternal health management. Prior to intervention, Solution Linked Group was not used to receive phone call from Community Skilled Birth Attendants. Community Skilled Birth Attendants were valued by the mothers. Mothers viewed that Community Skilled Birth Attendants are becoming confident in managing complication due

    β-1,3-Glucanase (EC 3.2.1.39) and chitinase (EC 3.2.1.14) mRNAs, proteins, and enzyme activities were expressed specifically in the micropylar tissues of imbibed tomato (Lycopersicon esculentum Mill.) seeds prior to radicle emergence. RNA hybridization and immunoblotting demonstrated that both enzymes were class I basic isoforms. β-1,3-Glucanase was expressed exclusively in the endosperm cap tissue, whereas chitinase localized to both endosperm cap and radicle tip tissues. β-1,3-Glucanase and chitinase appeared in the micropylar tissues of gibberellin-deficient gib-1 tomato seeds only when supplied with gibberellin. Accumulation of β-1,3-glucanase mRNA, protein and enzyme activity was reduced by 100 μM abscisic acid, which delayed or prevented radicle emergence but not endosperm cap weakening. In contrast, expression of chitinase mRNA, protein, and enzyme activity was not affected by abscisic acid. Neither of these enzymes significantly hydrolyzed isolated tomato endosperm cap cell walls. Although both β-1,3-glucanase and chitinase were expressed in tomato endosperm cap tissue prior to radicle emergence, we found no evidence that they were directly involved in cell wall modification or tissue weakening. Possible functions of these hydrolases during tomato seed germination are discussed. PMID:11457981

    2011-01-01

    Background Health care providers (HCPs) play an important role in public health emergency preparedness and response (PHEPR) so need to be aware of public health threats and emergencies. To inform HCPs, public health issues PHEPR messages that provide guidelines and updates, and facilitate surveillance so HCPs will recognize and control communicable diseases, prevent excess deaths and mitigate suffering. Public health agencies need to know that the PHEPR messages sent to HCPs reach their target audience and are effective and informative. Public health agencies need to know that the PHEPR messages sent to HCPs reach their target audience and are effective and informative. We conducted a literature review to investigate the systems and tools used by public health to generate PHEPR communications to HCPs, and to identify specific characteristics of message delivery mechanisms and formats that may be associated with effective PHEPR communications. Methods A systematic review of peer- and non-peer-reviewed literature focused on the following questions: 1) What public health systems exist for communicating PHEPR messages from public health agencies to HCPs? 2) Have these systems been evaluated and, if yes, what criteria were used to evaluate these systems? 3) What have these evaluations discovered about characterizations of the most effective ways for public health agencies to communicate PHEPR messages to HCPs? Results We identified 25 systems or tools for communicating PHEPR messages from public health agencies to HCPs. Few articles assessed PHEPR communication systems or messaging methods or outcomes. Only one study compared the effectiveness of the delivery format, device or message itself. We also discovered that the potential is high for HCPs to experience "message overload" given redundancy of PHEPR messaging in multiple formats and/or through different delivery systems. Conclusions We found that detailed descriptions of PHEPR messaging from public health to HCPs

    2011-01-01

    Although parents are assumed to be children’s primary models of socialization when it comes to gender, little is known about direct communication of gendered values in the family. Accordingly, this study assessed the amount and content of recalled parental gender socialization messages using data from 291 U.S. college undergraduates attending a large Midwestern university and 259 U.S. adolescents enrolled in public high schools in the Midwest. The study examined the amount and content of parental communications of five gendered discourses and then tested for connections to current gender beliefs. Findings indicate that gender socialization may be quite similar for sons and daughters, with some evidence of gender typing in patterns of communication. No significant age differences emerged in the patterns of socialization, although high school students reported receiving greater amounts of communication than college students on two of the five discourses. In general, receiving messages promoting traditional gender roles was associated with more traditional gender beliefs (and vice versa), although interpretation of some messages appeared to vary by gender.

  5. Environmental constraints shaping constituent order in emerging communication systems: Structural iconicity, interactive alignment and conventionalization.

    2016-01-01

    Where does linguistic structure come from? Recent gesture elicitation studies have indicated that constituent order (corresponding to for instance subject-verb-object, or SVO in English) may be heavily influenced by human cognitive biases constraining gesture production and transmission. Here we explore the alternative hypothesis that syntactic patterns are motivated by multiple environmental and social-interactional constraints that are external to the cognitive domain. In three experiments, we systematically investigate different motivations for structure in the gestural communication of simple transitive events. The first experiment indicates that, if participants communicate about different types of events, manipulation events (e.g. someone throwing a cake) and construction events (e.g. someone baking a cake), they spontaneously and systematically produce different constituent orders, SOV and SVO respectively, thus following the principle of structural iconicity. The second experiment shows that participants' choice of constituent order is also reliably influenced by social-interactional forces of interactive alignment, that is, the tendency to re-use an interlocutor's previous choice of constituent order, thus potentially overriding affordances for iconicity. Lastly, the third experiment finds that the relative frequency distribution of referent event types motivates the stabilization and conventionalization of a single constituent order for the communication of different types of events. Together, our results demonstrate that constituent order in emerging gestural communication systems is shaped and stabilized in response to multiple external environmental and social factors: structural iconicity, interactive alignment and distributional frequency.

    2004-01-01

    We have designed and developed a novel data communications network targeted at the provision of Emergency Medical Care in disaster situations over wide areas. The network nodes can transmit essential biosignals and in addition, support video and diagnostic quality sound (auscultation) broadcasting for teleconsultation purposes, by using a variety of wireless transports. The medical data acquisition stations are networked dynamically and on demand, with no requirement for an existing communications infrastructure at the disaster sites. The network design allows for limited transmitting station mobility and support for software-based Voice over IP during station roaming. Initial test results, following the hardware and software integration, indicate that the chosen network design meets specifications, and a full-scale field test, utilizing a large number of wireless stations operating under realistic conditions is to take place.

    Coordination of public communication has become a key issue in management of complex emergencies, and is a matter of debate between nuclear emergency management professionals. A particular problem is when inconsistent information is sent to the media and public by official sources from different levels, which has led to calls for a more coordinated approach. The IAEA created guidelines recommending a one-voice communication approach that provides clear, consistent and coordinated information by relevant stakeholders. The reviewed theory on the emergency communication coordination and the empirical results in this paper demonstrate some challenges regarding the feasibility of the above stated goal. This paper explores the communication process in the two-month period of the Fukushima nuclear emergency by using a quantitative comparative content and discourse analysis of 1340 printed media articles on the Fukushima nuclear disaster from two major newspapers in Spain ('El País' and 'El Mundo'), Italy ('Corriere della Sera' and 'La Repubblica'), Norway ('Aftenposten' and 'Dagsavisen'), Slovenia ('Delo' and 'Večer'), Belgium ('Le Soir' and 'De Standaard') and Russia ('Komsomolskaya Pravda' and 'Izvestiya'). The results show that it will be difficult to achieve a truly coordinated approach and one-voice communication in severe nuclear and radiological emergency due to the communication difficulties created by the dispersion of information sources, a broad and dispersed focus of the reported information, partially subjective and conflicting media reporting. The paper suggests ways to improve public communication coordination in nuclear and radiological disasters. PMID:27270489

    2014-01-01

    We analyzed audio recordings of telephone calls between emergency departments (EDs) and poison control centers (PCCs) in order to describe the information requirements for health information exchange. Analysis included a random sample of 120 poison exposure cases involving ED-PCC communication that occurred during 2009. We identified 52 information types characterized as patient or provider information, exposure information, ED assessment and treatment/ management, or PCC consultation. These information types constitute a focused subset of information that should be shared in the context of emergency treatment for poison exposure. Up to 60% of the information types identified in the analysis of call recordings can be represented using existing clinical terminology. In order to accomplish standards-based health information exchange between EDs and PCCs using data coded according to a standard clinical terminology system, it is necessary to define appropriate terms, information models and value sets.

    2016-01-01

    Background: Discharge instructions are vital in postemergency patient care to help the caregiver understand the diagnosis and identify symptoms which require prompt readmission. In general, oral or written instructions are provided on discharge. However, there is a dearth of information on the efficacy of discharge instructions provided by physicians in KSA. Objectives: To evaluate the efficacy of discharge instructions for postpediatrics emergency visit. Materials and Methods: This observational cross-sectional survey conducted in the Department of Paediatric Emergency at King Abdul Aziz Medical City, Riyadh, KSA, included 173 literate adult caregivers who had given their consent. Those who had been on admission earlier and been discharged from the emergency department were excluded. Demographic data and variables like knowledge of medicine and treatment follow-up were collected using a structured questionnaire and analyzed using SPSS version 16. Results: Verbal only, written only, or both verbal and written discharge instructions were provided. Written and verbal instructions, when provided together, were the most effective modes of communication with caregivers. The majority of the respondents were unaware of the follow-up plan (64.16%), unable to identify problems that would necessitate a follow-up (58.96%), and unable to identify the signs and symptoms that would require a revisit (62.43%) irrespective of the mode of instruction. However, more attention is necessary because of the 34.68% of the subjects who left the hospital without discharge instructions. Conclusions: Instructions given both verbally and in writing were observed to be more effective than verbal only or written only. The effectiveness of discharge instructions was highly influenced by the level of education of the caregivers. Improved caregiver friendly methods of communication from the pediatric emergency health-care team are necessary for the delivery of discharge instructions. PMID:27625582

    2015-01-01

    Purpose of review Microvesicles, in general, and exosomes together with their delivered content in particular, are now being widely recognized as key players in atherosclerosis. We have previously reviewed the role of microvesicles in atherosclerosis pathogenesis, diagnosis and therapy. Here, we focus on the roles of exosomes and discuss their emergent role in mediating activation and response to inflammation, vessel infiltration and induction of coagulation. We will finally give an outlook to discuss novel detection techniques and systems biology based data analyses to investigate exosome-mediated cell-to-cell communication. Recent findings Recent research points to a role of exosomes in delivering apoptotic and inflammatory content between blood cells and vascular cells, with a potential contribution of exosomes secreted by adipose tissue. An atheroprotective role of exosomes in response to coagulation that may contrast with the procoagulatory role of platelet-derived larger microvesicles is envisaged. New detection and separation methods and systems biology techniques are emerging. Conclusion We project that the development of novel detection, separation and analysis mechanism and systems-based analysis methods will further unravel the paracrine and endocrine ‘communication protocol’ between cellular players in atherosclerosis, mediating inflammation, oxidative stress and apoptosis.

    The aim of this study was to evaluate WhatsApp messenger usage for communication between consulting and emergency physicians. A retrospective, observational study was conducted in the emergency department (ED) of a tertiary care university hospital between January 2014 and June 2014. A total of 614 consultations requested by using the WhatsApp application were evaluated, and 519 eligible consultations were included in the study. The WhatsApp messages that were transferred to consultant physicians consisted of 510 (98.3 %) photographic images, 517 (99.6 %) text messages, 59 (11.3 %) videos, and 10 (1.9 %) voice messages. Consultation was most frequently requested from the orthopedics clinic (n = 160, 30.8 %). The majority of requested consultations were terminated only by evaluation via WhatsApp messages. (n = 311, 59.9 %). Most of the consulting physicians were outside of the hospital or were mobile at the time of the consultation (n = 292, 56.3 %). The outside consultation request rate was significantly higher for night shifts than for day shifts (p = .004), and the majority of outside consultation request were concluded by only WhatsApp application (p < .001). WhatsApp is useful a communication tool between physicians, especially for ED consultants who are outside the hospital, because of the ability to transfer large amounts of clinical and radiological data during a short period of time.

In February 2013 a sinkhole opened beneath a Florida Home resulting in the loss of a life and demolition of the affected home. The resulting void was in the order of 15 m deep. Neighbouring homes also had to be demolished. Television footage of this unfortunate incident resonated with an Assistant Commissioner of the London Fire Brigade who questioned whether or not such a feature would be recognised in the UK and if so, how the emergency response would be managed. Stemming from this, the British Geological Survey was invited to work with the Chief Fire Officers Association Urban Search and Rescue working group on geohazards. The aim of this group was to develop national tactical operational guidance on geohazards that would form the basis for regional guidance and training. The project was addressed collaboratively providing opportunities for two students from the Coventry University Disaster Management course, that were on placements with Avon Fire and Rescue, to work with the BGS to develop the guidance. Key to the success of the project was an iterative approach to knowledge exchange with respect to firstly, the characterization of the geohazards, and the processes and uncertainties associated with them and secondly, with respect to emergency responders' needs and priorities. Effective communication was achieved through challenging and rationalising the geoscience language for the end user and through a series of customised

    2012-12-01

    Effective communication in healthcare is important and especially critical in emergency situations. In this paper we propose a new comprehensive emergency system which facilitates the communication process in emergency cases from ambulance dispatch to the patient's arrival and handover in the hospital. The proposed system has been designed to facilitate and computerize all the processes involved in an accident from finding the nearest ambulance through to accessing a patient's online health record which can assist in pre-hospital treatments. The proposed system also locates the nearest hospital specializing in the patient's condition and will communicate patient identification to the emergency department. The components of the proposed system and the technologies used in building this system are outlined in this paper as well as the challenges expected and proposed solutions to these challenges.

    With the threat posed by terrorism involving radioactive materials now high on the nation's agenda, local, state, and federal agencies are moving to enhance preparedness and response capabilities. Crucial to these efforts is the development of effective risk communication strategies. This article reports findings from an ongoing study of risk communication issues in nuclear/radiological terrorism situations. It is part of a larger CDC-funded effort that aims to better understand communication challenges associated with weapons of mass destruction terrorism incidents. Presented here are formative research findings from 16 focus groups (n = 163) in which a multi-part, hypothetical radioactive materials terrorism situation was discussed. Twelve of the focus groups were carried out with members of the general public (drawn from a variety of ethnic backgrounds and geographic locations), and four groups were composed of first responders, hospital emergency department personnel, and public health professionals. One aim of the focus groups was to elicit detailed information on people's knowledge, views, perceptions, reactions, and concerns related to a nuclear/radiological terrorism event, and to better understand people's specific information needs and preferred information sources. A second aim was to pretest draft informational materials prepared by CDC and NIOSH. Key findings for the public and professional groups are presented, and the implications of the research for developing messages in radiological/nuclear terrorism situations are explored.

    Background Reliance on surveys and qualitative studies of trainees to guide postgraduate education about palliative and end of life (EOL) communication may lead to gaps in the curriculum. We aimed to develop a deeper understanding of internal medicine trainees’ educational needs for a palliative and EOL communication curriculum and how these needs could be met. Methods Mixed methods, including a survey and focus groups with trainees, and interviews with clinical faculty and medical educators, were applied to develop a broader perspective on current experiences and needs for further education. Quantitative descriptive and thematic analyses were conducted. Results Surveyed trainees were least confident and least satisfied with teaching in counseling about the emotional impact of emergencies and discussing organ donation. Direct observation with feedback, small group discussion, and viewing videos of personal consultations were perceived as effective, yet infrequently identified as instructional methods. Focus groups and interviews identified goals of care conversations as the highest educational priority, with education adapted to learner needs and accompanied by feedback and concurrent clinical and organizational support. Conclusions Our work expands on previous research describing needs for postgraduate education in palliative and EOL communication to include the importance of support, culture change, and faculty development, and provides insight into why such needs exist.

    Of the 2790 local health departments (LHDs) in the United States, Internet homepages were located for 1986. We reviewed each homepage to document the presence of 9 elements deemed to be critical for effective communications during emergency or disaster situations. LHD Web site homepages had a mean of 4.1 (±1.4) elements. Among the findings, this review revealed that 4 of 5 (80.5%) of the LHDs included the agency phone number, half (49.4%) provided links to emergency information, and about 1 in 5 (19.6%) listed an agency e-mail address. Fewer than 1 in 20 (4.3%) of the LHD homepages reviewed allowed visitors to sign up for automatic alerts or notifications. We suggest that these results be used as a starting point in developing a standardized template containing the 9 homepage elements. Such a template complements National Incident Management System protocols and can provide a recognizable source of consistent and reliable information for people during a public health emergency or disaster.

    In an emergency department (ED), discharge communication represents a crucial step in medical care. In theory, it fosters patient satisfaction and adherence to medication, reduces anxiety, and ultimately promotes better outcomes. In practice, little is known about the extent to which patients receiving discharge information understand their medical condition and are able to memorize and retrieve instructions. Even less is known about the ideal content of these instructions. Focusing on patients with chest pain, we systematically assessed physicians' and patients' informational preferences and created a memory aid to support both the provision of information (physicians) and its retrieval (patients). In an iterative process, physicians of different specialties (N = 47) first chose which of 81 items to include in an ED discharge communication for patients with acute chest pain. A condensed list of 34 items was then presented to 51 such patients to gauge patients' preferences. Patients' and physicians' ratings of importance converged in 32 of the 34 items. Finally, three experts grouped the 34 items into five categories: (1) information on diagnosis; (2) follow-up suggestions; (3) advice on self-care; (4) red flags; and (5) complete treatment, from which we generated the mnemonic acronym "InFARcT." Defining and structuring the content of discharge information seems especially important for ED physicians and patients, as stress and time constraints jeopardize effective communication in this context. Chest pain accounts for up to 10% of all patient presentations in emergency departments (EDs) (Konkelberg & Esterman, 2003). The majority of these patients will usually be discharged within hours, after exclusion of serious conditions such as myocardial infarction (Goodacre et al., 2011). A comprehensive workup of low- to intermediate-risk patients is not feasible in the ED (Reichlin et al., 2009). Yet many of these patients go on to suffer from repeated episodes of chest

    This paper examines the implications of emerging interdependencies between the electric power grid and Information and Communication Technology (ICT). Over the past two decades, electricity and ICT infrastructure have become increasingly interdependent, driven by a combination of factors including advances in sensor, network and software technologies and progress in their deployment, the need to provide increasing levels of wide-area situational awareness regarding grid conditions, and the promise of enhanced operational efficiencies. Grid operators’ ability to utilize new and closer-to-real-time data generated by sensors throughout the system is providing early returns, particularly with respect to management of the transmission system for purposes of reliability, coordination, congestion management, and integration of variable electricity resources such as wind generation.

    A quick-reaction emergency satellite, cellular and microwave communications package known as the National Transportable Telecommunications Capability (NTTC) is discussed. The NTTC is designed to restore 'last mile' connectivity to remote or isolated areas in the U.S. or abroad that have been devastated by hurricanes, earthquakes, or other natural or manmade disasters. The NTTC is self-contained for rapid airlift in a single C-130 military transport, or may be transported by land or sea as appropriate. The NTTC operates over a Ku-band domestic satellite back into a gateway station and into the Public Switched Network, FTS-2000, and other military networks. Built with commercial off-the-shelf components, the NTTC is designed to respond to the telecommunication needs of critical NS/EP functions and users.

    During disasters, the needs of victims outstrip available resources. Rapid assessment of patients must be performed; however, language barriers can be an impediment to efficient patient assessment, especially if interpreter resources are limited. Dependency on interpretive services requiring technology such a telephones, cell phones, and video conferencing may be inefficient, as they may be unavailable during disaster conditions. A low-tech, portable tool that aids in communication with non-English speakers would be beneficial. The medical emergency communication (MEC) book, developed at Children's Hospital Los Angeles, has the potential to be a useful tool in this capacity. The goal of this pilot study was to compare the accuracy of a newly developed disaster-focused medical history obtained from Spanish-speaking patients or caregivers using the MEC book, compared to a control group with whom no book was used. Our hypothesis was that use of the MEC book improves accuracy of medical history taking between English-only speaking health care workers and Spanish-speaking patients better than a monolingual clinician trying to take a medical history without it. We anticipated a higher overall score in the group of subjects whose histories were taken using the MEC book than in the control group. Patient satisfaction with the MEC book also was measured.

    More than 200 studies of warning systems and warning response were reviewed for this social science perspective and state-of-the-art assessment of communication of emergency public warnings. The major findings are as follows. First, variations in the nature and content of warnings have a large impact on whether or not the public heeds the warning. Relevant factors include the warning source; warning channel; the consistency, credibility, accuracy, and understandability of the message; and the warning frequency. Second, characteristics of the population receiving the warning affect warning response. These include social characteristics such as gender, ethnicity and age, social setting characteristics such as stage of life or family context, psychological characteristics such as fatalism or risk perception, and knowledge characteristics such as experience or training. Third, many current myths about public response to emergency warning are at odds with knowledge derived from field investigations. Some of these myths include the keep it simple'' notion, the cry wolf'' syndrome, public panic and hysteria, and those concerning public willingness to respond to warnings. Finally, different methods of warning the public are not equally effective at providing an alert and notification in different physical and social settings. Most systems can provide a warning given three or more hours of available warning time. Special systems such as tone-alert radios are needed to provide rapid warning. 235 refs., 8 figs., 2 tabs.

  3. Emergence of long-range correlations and bursty activity patterns in online communication

    2015-12-01

    Research has suggested that the activity occurring in a variety of social, economic, and technological systems exhibits long-range fluctuations in time. Pronounced levels of rapidly occurring events are typically observed over short periods of time, followed by long periods of inactivity. Relatively few studies, however, have shed light on the degree to which inhomogeneous temporal processes can be detected at, and emerge from, different levels of analysis. Here we investigate patterns of human activity within an online forum in which communication can be assessed at three intertwined levels: the micro level of the individual users; the meso level of discussion groups and continuous sessions; and the macro level of the whole system. To uncover the relation between different levels, we conduct a number of numerical simulations of a zero-crossing model in which users' behavior is constrained by progressively richer and more realistic rules of social interaction. Results indicate that, when users are solipsistic, their bursty behavior is not sufficient for generating heavy-tailed interevent time distributions at a higher level. However, when users are socially interdependent, the power spectra and interevent time distributions of the simulated and real forums are remarkably similar at all levels of analysis. Social interaction is responsible for the aggregation of multiple bursty activities at the micro level into an emergent bursty activity pattern at a higher level. We discuss the implications of the findings for an emergentist account of burstiness in complex systems.

    BACKGROUND: Communication failure in prehospital emergency medicine can affect patient safety as it does in other areas of medicine as well. We analyzed the database of the critical incident reporting system for prehospital emergency medicine in Germany retrospectively regarding communication errors. METHODS: Experts of prehospital emergency medicine and risk management screened the database for verbal communication failure, non-verbal communication failure and missing communication at all. RESULTS: Between 2005 and 2015, 845 reports were analyzed, of which 247 reports were considered to be related to communication failure. An arbitrary classification resulted in six different kinds: 1) no acknowledgement of a suggestion; 2) medication error; 3) miscommunication with dispatcher; 4) utterance heard/understood improperly; 5) missing information transfer between two persons; and 6) other communication failure. CONCLUSION: Communication deficits can lead to critical incidents in prehospital emergency medicine and are a very important aspect in patient safety. PMID:27313802

    A new theoretical framework (PPSMC) applicable to synesthesia has been proposed, in which the discrepancy between the perceptual reality of (some) synesthetic concurrents and their subjective non-veridicality is being explained. The PPSMC framework stresses the relevance of the phenomenology of synesthesia for synesthesia research-and beyond. When describing the emergence and persistence of synesthetic concurrents under PPSMC, it is proposed that precise, high-confidence priors are crucial in synesthesia. I discuss the construction of priors in synesthesia. PMID:24702569

  6. Predictors of emergency room visits or acute hospital admissions prior to death among hospice palliative care clients in Ontario: a retrospective cohort study

    2014-01-01

    Background Hospice palliative care (HPC) is a philosophy of care that aims to relieve suffering and improve the quality of life for clients with life-threatening illnesses or end of life issues. The goals of HPC are not only to ameliorate clients’ symptoms but also to reduce unneeded or unwanted medical interventions such as emergency room visits or hospitalizations (ERVH). Hospitals are considered a setting ill-prepared for end of life issues; therefore, use of such acute care services has to be considered an indicator of poor quality end of life care. This study examines predictors of ERVH prior to death among HPC home care clients. Methods A retrospective cohort study of a sample of 764 HPC home care clients who received services from a community care access centre (CCAC) in southern Ontario, Canada. All clients were assessed using the Resident Assessment Instrument for Palliative Care (interRAI PC) as part of normal clinical practice between April 2008 and July 2010. The Andersen-Newman framework for health service utilization was used as a conceptual model for the basis of this study. Logistic regression and Cox regression analyses were carried out to identify predictors of ERVH. Results Half of the HPC clients had at least one or more ERVH (n = 399, 52.2%). Wish to die at home (OR = 0.54) and advanced care directives (OR = 0.39) were protective against ERVH. Unstable health (OR = 0.70) was also associated with reduced probability, while infections such as prior urinary tract infections (OR = 2.54) increased the likelihood of ERVH. Clients with increased use of formal services had reduced probability of ERVH (OR = 0.55). Conclusions Findings of this study suggest that predisposing characteristics are nearly as important as need variables in determining ERVH among HPC clients, which challenges the assumption that need variables are the most important determinants of ERVH. Ongoing assessment of HPC clients is essential in reducing ERVH

    In October 2007, wildfires burned nearly 300,000 acres in San Diego County, California. Emergency risk communication messages were broadcast to reduce community exposure to air pollution caused by the fires. The objective of this investigation was to determine residents' exposure to, understanding of, and compliance with these messages. From March to June 2008, the authors surveyed San Diego County residents using a 40-question instrument and random digit dialing. The 1,802 respondents sampled were predominantly 35-64 years old (65.9%), White (65.5%), and educated past high school (79.0%). Most (82.5%) lived more than 1 mile away from the fires, although many were exposed to smoky air for 5-7 days (60.7%) inside and outside their homes. Most persons surveyed reported hearing fire-related health messages (87.9%) and nearly all (97.9%) understood the messages they heard. Respondents complied with most to all of the nontechnical health messages, including staying inside the home (58.7%), avoiding outdoor exercise (88.4%), keeping windows and doors closed (75.8%), and wetting ash before cleanup (75.6%). In contrast, few (<5%) recalled hearing technical messages to place air conditioners on recirculate, use High-Efficiency Particulate Air filters, or use N-95 respirators during ash cleanup, and less than 10% of all respondents followed these specific recommendations. The authors found that nontechnical message recall, understanding, and compliance were high during the wildfires, and reported recall and compliance with technical messages were much lower. Future disaster health communication should further explore barriers to recall and compliance with technical recommendations. PMID:22494384

    Objective This review aims to identify and assess evidence on interventions to communicate risk and promote disease mitigation measures in epidemics and emerging disease outbreak settings. The study focuses on data that are relevant to low and middle-income country (LMIC) settings. Methods We conducted a comprehensive literature search using five major electronic databases (Pubmed Medline, Biomed Central, EMBASE, Science of Citation Index, and Cochrane Library) and other sources to identify relevant studies published from January 2002 to July 2013. The review was guided by the socio-ecological model/perspective of public health and the ideation theory and focused on interventions at the community, healthcare, and multi-sectoral settings, which also reflect key intervention levels of the Ottawa Charter for Health Promotion. Eligible quantitative studies were selected according to specific study criteria and assessed using the Critical Appraisal Skills Program (CASP) framework. Conversely, qualitative studies, reviews, case studies, and editorials were not included. Studies were selected by two independent reviewers. Results Twenty-nine relevant studies from 16 countries were included. Most studies focused on a single intervention or intervention level, rather than multi-sectoral interventions. The majority of the evidence relates to programs aimed at behavioral and social results (or relevant intermediate steps) within a specific population group. Two studies included implications for improvements in health service delivery, two studies examined the intervention’s impact on health systems-related outcomes, and three had also implications for environmental health outcomes. Cost- and health equity-related implications for select evidence were also discussed. Conclusions The paucity of well-designed quantitative evaluations of interventions to communicate health risk and promote disease control measures in LMICs does not allow for any definitive conclusions. Yet, the

    Objectives. We sought to better understand the challenges of communicating with the public about emerging health threats, particularly threats involving toxic chemicals, biological agents, and radioactive materials. Methods. At the request of the Centers for Disease Control and Prevention, we formed an interdisciplinary consortium of investigative teams from 4 schools of public health. Over 2 years, the investigative teams conducted 79 focus group interviews with 884 participants and individual cognitive response interviews with 129 respondents, for a total sample of 1013 individuals. The investigative teams systematically compared their results with other published research in public health, risk communication, and emergency preparedness. Results. We found limited public understanding of emerging biological, chemical, and radioactive materials threats and of the differences between them; demand for concrete, accurate, and consistent information about actions needed for protection of self and family; active information seeking from media, local authorities, and selected national sources; and areas in which current emergency messaging can be improved. Conclusions. The public will respond to a threat situation by seeking protective information and taking self-protective action, underlining the critical role of effective communication in public health emergencies.

    In the late 1968, the Space Technology Application Office at the Jet Propulsion Laboratory (JPL) initiated a pilot study to determine whether technological aids could be developed that would help secondary school administrators cope with the volatile and chaotic situations that often accompany student activism, disorders, and riots. The study was conducted in cooperation with the Sacramento City Unified School District (SCUSD) and at the John F. Kennedy Senior High School (JFK) in Sacramento, California. The problems at JFK and in the SCUSD were identified and described to the JPL team by members of the Kennedy staff and personnel at various levels and departments within the school district. The JPL team of engineers restricted their scope to problems that appeared solvable, or at least partially solvable, through the use of technological systems. Thus far, two hardware systems have been developed for use in the school. The first, a personal emergency assistance communication system, has already been tested operationally at JFK and has met the objectives established for it. The second technological aid developed was a computerized attendance accounting system. This system has been fabricated, tested, and installed at JFK. Full-scale operational testing began in April 1971. While studies and hardware tests were in progress at JFK, contacts were made with several other schools in order that, insofar as practicable, hardware designs could allow for possible adaptation to schools other than JFK.

    ABSTRACT An emerging Mycobacterium tuberculosis complex (MTC) pathogen, M. mungi, infects wild banded mongooses (Mungos mungo) in Northern Botswana, causing significant mortality. This MTC pathogen did not appear to be transmitted through a primary aerosol or oral route. We utilized histopathology, spoligotyping, mycobacterial interspersed repetitive units-variable number of tandem repeats (MIRU-VNTR), quantitative PCR (qPCR), and molecular markers (regions of difference [RDs] from various MTC members, including region of difference 1 [RD1] from M. bovis BCG [RD1BCG], M. microti [RD1mic], and M. pinnipedii [RD1seal], genes Rv1510 [RD4], Rv1970 [RD7], Rv3877/8 [RD1], and Rv3120 [RD12], insertion element IS1561, the 16S RNA gene, and gene Rv0577 [cfp32]), including the newly characterized mongoose-specific deletion in RD1 (RD1mon), in order to demonstrate the presence of M. mungi DNA in infected mongooses and investigate pathogen invasion and exposure mechanisms. M. mungi DNA was identified in 29% of nasal planum samples (n = 52), 56% of nasal rinses and swabs (n = 9), 53% of oral swabs (n = 19), 22% of urine samples (n = 23), 33% of anal gland tissue (n = 18), and 39% of anal gland secretions (n = 44). The occurrence of extremely low cycle threshold values obtained with qPCR in anal gland and nasal planum samples indicates that high levels of M. mungi can be found in these tissue types. Histological data were consistent with these results, suggesting that pathogen invasion occurs through breaks in the nasal planum and/or skin of the mongoose host, which are in frequent contact with anal gland secretions and urine during olfactory communication behavior. Lesions in the lung, when present, occurred only with disseminated disease. No environmental sources of M. mungi DNA could be found. We report primary environmental transmission of an MTC pathogen that occurs in association with social communication behavior. PMID:27165798

    2015-01-01

    Overview: South Asian countries have experienced a remarkable economic growth during last two decades along with subsequent transformation in social, economic and food systems. Rising disposable income levels continue to drive the nutrition transition characterized by a shift from a traditional high-carbohydrate, low-fat diets towards diets with a lower carbohydrate and higher proportion of saturated fat, sugar and salt. Steered by various transitions in demographic, economic and nutritional terms, South Asian population are experiencing a rapidly changing disease profile. While the healthcare systems have long been striving to disentangle from the vicious cycle of poverty and undernutrition, South Asian countries are now confronted with an emerging epidemic of obesity and a constellation of other non-communicable diseases (NCDs). This dual burden is bringing about a serious health and economic conundrum and is generating enormous pressure on the already overstretched healthcare system of South Asian countries. Objectives: The Nutrition transition has been a very popular topic in the field of human nutrition during last few decades and many countries and broad geographic regions have been studied. However there is no review on this topic in the context of South Asia  as yet. The main purpose of this review is to highlight the factors accounting for the onset of nutrition transition and its subsequent impact on epidemiological transition in five major South Asian countries including Bangladesh, India, Nepal, Pakistan and Sri Lanka. Special emphasis was given on India and Bangladesh as they together account for 94% of the regional population and about half world’s malnourished population. Methods: This study is literature based. Main data sources were published research articles obtained through an electronic medical databases search. PMID:26834976

    2014-01-01

    Short message service (SMS) text messaging can be useful for communicating information to public health employees and improving workforce situational awareness during emergencies. We sought to understand how the 1,500 employees at Public Health – Seattle & King County, Washington, perceived barriers to and benefits of participation in a voluntary, employer-based SMS program. Based on employee feedback, we developed the system, marketed it, and invited employees to opt in. The system was tested during an ice storm in January 2012. Employee concerns about opting into an SMS program included possible work encroachment during non-work time and receiving excessive irrelevant messages. Employees who received messages during the weather event reported high levels of satisfaction and perceived utility from the program. We conclude that text messaging is a feasible form of communication with employees during emergencies. Care should be taken to design and deploy a program that maximizes employee satisfaction.

    2016-01-01

    Background: Many low- and middle-income countries depend on emergency medical technicians (EMTs), nurses, midwives, and layperson community health workers with limited training to provide a majority of emergency medical, trauma, and obstetric care in the prehospital setting. To improve timely patient care and expand provider scope of practice, nations leverage cellular phones and call centers for real-time online medical direction. However, there exist several barriers to adequate communication that impact the provision of emergency care. We sought to identify obstacles in the cellular communication process among GVK Emergency Management and Research Institute (GVK EMRI) EMTs in Gujarat, India. Methods: A convenience sample of practicing EMTs in Gujarat, India were surveyed regarding the barriers to call initiation and completion. Results: 108 EMTs completed the survey. Overall, ninety-seven (89.8%) EMTs responded that the most common reason they did not initiate a call with the call center physician was insufficient time. Forty-six (42%) EMTs reported that they were unable to call the physician one or more times during a typical workweek (approximately 5-6 twelve-hour shifts/week) due to their hands being occupied performing direct patient care. Fifty-eight (54%) EMTs reported that they were unable to reach the call center physician, despite attempts, at least once a week. Conclusion: This study identified multiple barriers to communication, including insufficient time to call for advice and inability to reach call center physicians. Identification of simple interventions and best practices may improve communication and ensure timely and appropriate prehospital care.  PMID:27551654

    Little is known about adult women with attention-deficit/hyperactivity disorder (ADHD); however, available evidence suggests that they experience social impairment. Online social networking websites such as Facebook have become endemic outlets through which emerging adults communicate with peers. No study has examined the peer interactions of emerging adults with childhood histories of ADHD in this developmentally relevant online domain. Participants in the current study were an ethnically diverse sample of 228 women, 140 of whom met diagnostic criteria for ADHD in childhood and 88 who composed a matched comparison sample. These women were assessed at 3 time points spanning 10 years (mean age = 9.6 at Wave 1, 14.1 at Wave 2, 19.6 at Wave 3). After statistical control of demographic covariates and comorbidities, childhood ADHD diagnosis predicted, by emerging adulthood, a greater stated preference for online social communication and a greater tendency to have used online methods to interact with strangers. A childhood diagnosis of ADHD also predicted observations of fewer Facebook friends and less closeness and support from Facebook friends in emerging adulthood. These associations were mediated by a composite of face-to-face peer relationship impairment during childhood and adolescence. Intriguingly, women with persistent diagnoses of ADHD from childhood to emerging adulthood differed from women with consistent comparison status in their online social communication; women with intermittent diagnoses of ADHD had scores intermediate between the other 2 groups. Results are discussed within the context of understanding the social relationships of women with childhood histories of ADHD. PMID:25894439

    2004-01-01

    Despite the explosion of online communication in the community, its use between patients and their health care providers remains low. However, rapidly growing patient and provider interest in using online communication has motivated organizations to consider options for deploying these new tools in clinical practice. In this paper, we describe the barriers and challenges health care providers and their organizations must address in developing and deploying these new tools. We formulate lessons from early experiences with e-mail and web-based communication in clinical settings. Finally, we provide a roadmap for developing and deploying these new tools in clinical practice. Health care providers and their organizations will need to consider issues related to technology, data management, operations, communication management, and financial support in order to successfully deploy online services and communication for patients in clinical settings.

    The model for emergency department (ED) end-of-life communications after acute devastating events addresses decision-making capacity, surrogates, and advance directives, including legal definitions and application of these steps. Part II concerns communications moving from resuscitative to palliative and end-of-life treatments. After completing the steps involved in determining decision-making, emergency physicians (EPs) should consider starting palliative measures versus continuing resuscitative treatment. As communications related to these end-of-life decisions increasingly fall within the scope of emergency medicine (EM) practice, we need to become educated about and comfortable with them.

  7. EMERGENCE OF POLYCENTRIC URBAN CONFIGURATIONS FROM COMBINATION OF COMMUNICATION EXTERNALITY AND SPATIAL COMPETITION

    NASA Astrophysics Data System (ADS)

    Takayama, Yuki; Akamatsu, Takashi

    It is believed in urban economics that a polycentric urban configuration emerges only when the multiple-types of agents compete for land (Fujita and Thisse, 2002, p.209). This paper discloses that the polycentric urban configuration emerges in a single-type agent model. We also show that the dispersion force with a spill-over effect and its distance decay property are necessary for the emergence of the polycentric configuration. To show this, we compare two types of social interaction models, SI model and SISC model, each of which has a different dispersion force: the former model's dispersion force consists of land rent, and the latter consists of spatial competition. The analysis of two models proves that the polycentric configuration emerges in the SISC model, while this configuration never emerges in the SI model.

    Young children with autism spectrum disorder meet significant challenges in joint attention skills and in social communication. A child-centered, improvisational, music therapy intervention model was implemented to promote engagement in three young children with autism in a kindergarten classroom. A multiple baseline design compared the children's performance through three phases of intervention: focus on faces, response to joint attention, and initiation of joint attention. A complimentary qualitative analysis of teacher and parent experiences allowed for an in-depth understanding of the role of social environment in supporting emerging social communication skills among three children. As all children showed improvement in joint attention and actions of social engagement, this study bears evidence on the potential of music therapy as a promising intervention for promoting social skills of young children with autism spectrum disorder.

    This presentation will describe a collaborative dialogue process between earth scientists and emergency management officials that focused on translation of science into policy, building long term trust based relationships between sectors and unified presentation of hazards, risks and consequence management to public officials and the general public. The author will describe the structure and process of the California Earthquake Prediction Evaluation Council (CEPEC) in assessing the credibility of long and short term earthquake predictions, assessment of risk, and the formulation of public communication strategies and preparatory actions by government agencies. For nearly 4 decades, earth scientists, politically appointed state officials and emergency managers have engaged in ongoing discussions of the policy implications of research on potential seismic risk. Some discussions were scheduled and occurred over months, and others were ad hoc and occurred in the minutes between potential precursory incidents and possible large events. The effectiveness of this process was dependent on building respect for ones counterparts expertise, bias and responsibilities, clear communication of data, uncertainty and knowledge of the physical models assumed, history and probabilities; and the physical and political consequences of possible events; and the costs and economic and social disruption of alternative preparedness actions. But, the dialogue included political and social scientists, representatives of the print and broadcast media, political and management officials from federal, state and local governments. The presentation will provide an assessment of the effectiveness of the collaborative dialogue process and lessons on sustaining a long term partnership among the participating federal, state and local officials.

    Experiments on the quick-relief medical communications via the CS-2 satellite were carried out by using two types of 30/20GHz small transportable earth stations whose antenna diameters are 1 and 2 m. As the terminal equipments, FM-SCPC systems with a one-telephone-equivalent channel were prepared for the transmission of voice, color freezed picture (9.6 kbps), supersonic echo signal and heart sound from a electro-cardiograph. Signals from various medical equipments were transmitted by an FM-SCPC system from Simizu harbour (1 m station) to Tokyo transportable station (2 m), assuming that a person was injured in the ship and the ship came alongside the pier. Transmitted materials are mainly various kinds of pictures of affected parts, X-ray films and electro-cardiograph with breathing sounds. It was found possible to send various medical information mentioned above via CS-2 by the 30/20GHz simple communication systems with one-telephone-equivalent channel. Doctors suggested it would be possible to judge very well about the patients' emergency conditions and to give quick consult with inevitable treatment procedures for them. However, a few problems were found in the Hi-Fi reproduction of original colors and in the transmission of heart sounds in the very low frequency band less than 300 Hz.

    Objective To document and explore the views and experiences of key stakeholders regarding the consent procedures of an emergency research clinical trial examining immediate fluid resuscitation strategies, and to discuss the implications for similar trials in future. Methods A social science sub-study of the FEAST (Fluid Expansion As Supportive Therapy) trial. Interviews were held with trial team members (n = 30), health workers (n = 15) and parents (n = 51) from two purposively selected hospitals in Soroti, Uganda, and Kilifi, Kenya. Findings Overall, deferred consent with prior assent was seen by staff and parents as having the potential to protect the interests of both patients and researchers, and to avoid delays in starting treatment. An important challenge is that the validity of verbal assent is undermined when inadequate initial information is poorly understood. This concern needs to be balanced against the possibility that full prior consent on admission potentially causes harm through introducing delays. Full prior consent also potentially imposes worries on parents that clinicians are uncertain about how to proceed and that clinicians want to absolve themselves of any responsibility for the child’s outcome (some parents’ interpretation of the need for signed consent). Voluntariness is clearly compromised for both verbal assent and full prior consent in a context of such vulnerability and stress. Further challenges in obtaining verbal assent were: what to do in the absence of the household decision-maker (often the father); and how medical staff handle parents not giving a clear agreement or refusal. Conclusion While the challenges identified are faced in all research in low-income settings, they are magnified for emergency trials by the urgency of decision making and treatment needs. Consent options will need to be tailored to particular studies and settings, and might best be informed by consultation with staff members and community

    Sparked by awareness of the limitations to provide medical services in remote areas, researchers have perceived that developing telemedicine systems is inevitable. In most cases very remote areas and disaster struck areas lack telecommunication infrastructure. Telemedicine system operating in such areas must have advanced wireless technology supporting it in devastating situation, hence it is called as tele-emergency system. Our approach is on MANET combined with Mobile IP and MIPV6, is the basis of infrastructure for the mobile tele-emergency system. The tele-emergency system requires data, voice and video transmission in its network. In this investigation, evaluation is based on simulation of the various ITU-T standard CODECs of VoIP and video transmission over MANET using discrete event simulator NS-2. The results of simulation showed that ITU-T G723.1 worked well in the MANET environment than the other CODECs for VoIP in fixed and mobility tele-emergency environments. From the simulation of video CODEC performance evaluation, it was observed that H.263 performed to a great extent in random small scale environment and also in multiple video flow of 57.6kbps speed video transmission.

    The article presents a study of the interaction between paramedics and parents in cases of Sudden Infant Death Syndrome (SIDS). We have sought to understand how the parents perceived the paramedics ability to communicate as well as empathise and deal with practical aspects of the situation. We have also sought to understand how the paramedics view their role as professional health workers, and how they think they should interact with persons in crisis. The method used in this study is qualitative and involves semi-structured interview schemes. We conducted twelve interviews – six with parents and six with paramedics. One of our primary findings is that many of the parents interviewed were not satisfied with the paramedics' communication, empathy and ability to take care of the practical aspects of the situation. The interviews have also revealed that there is significant disagreement among paramedics about the interpersonal role of health workers in situations involving people in crisis. The final part of this article includes a discussion of these and other findings. We argue that guidelines that specify threshold conditions for communication and care should be implemented in education and training. The aim of such guidelines should be to make sure that parents of lifeless children are secured a minimum of relevant explanations, information and care. PMID:18957067

  8. Non-communicable diseases: is their emergence in industrialized societies related to changes in neuroendocrine function?

    PubMed

    Bickler, S W

    2000-05-01

    This hypothesis suggests that industrialization alters the human neuroendocrine system. The neuroendocrine changes come about because of changes in environmental stimuli. It is further proposed that changes in neuroendocrine function can account for the contrasting pattern of non-communicable diseases in traditional and industrialized societies. The hypothesis is based on subtle clinical differences in traditional and industrialized societies, and the evolving concept of neuroendocrine regulation of physiological processes. Compared to traditional societies, individuals from industrialized communities tend to have lower pain tolerance, slower gastrointestinal transit-time, and a greater chance of having a calcified pineal gland. These changes parallel the increasing incidence of non-communicable diseases in industrialized societies. There is sufficient reason to suspect the variations in pain tolerance, gastrointestinal transit-time and pineal gland calcification represent changes in neuroendocrine function. Programming of the neuroendocrine system by environmental events early in life is one possible mechanism whereby these changes might be effected. Understanding the physiological changes that occur with industrialization, and how environmental stimuli interact with the developing neuroendocrine system might lead to new strategies for the prevention and treatment of non-communicable diseases.

    The transition from paper to electronic-based records in the healthcare industry has posed several challenges to conventional medical practices. The introduction of technology in day-to-day medical and nursing practices deserves careful consideration. In this work, we report the results of a controlled experiment to compare nurses' consultation in emergency calls in six different conditions. We studied the effect that the type of communication media (face-to-face, telephone, videoconference) and type of nursing protocol media (paper-based, electronic-based) can have on consultation time, mistakes made, pauses during consultation, eye contact, and efficacy of the consultation. We found that the type of communication media has an effect on consultation time; on average, fewer mistakes were made during telephone-based consultations; for eye contact, there were significantly fewer eye contacts during face-to-face than during videoconference consultations; finally, the type of communication media or protocol media did not have any effect in the efficacy of the consultation.

    The wireless mobile service with a high bit rate using CDMA-1X EVDO is now widely used in Korea. Mobile devices are also increasingly being used as the conventional communication mechanism. We have developed a web-based mobile system that communicates patient information and images, using CDMA-1X EVDO for emergency diagnosis. It is composed of a Mobile web application system using the Microsoft Windows 2003 server and an internet information service. Also, a mobile web PACS used for a database managing patient information and images was developed by using Microsoft access 2003. A wireless mobile emergency patient information and imaging communication system is developed by using Microsoft Visual Studio.NET, and JPEG 2000 ActiveX control for PDA phone was developed by using the Microsoft Embedded Visual C++. Also, the CDMA-1X EVDO is used for connections between mobile web servers and the PDA phone. This system allows fast access to the patient information database, storing both medical images and patient information anytime and anywhere. Especially, images were compressed into a JPEG2000 format and transmitted from a mobile web PACS inside the hospital to the radiologist using a PDA phone located outside the hospital. Also, this system shows radiological images as well as physiological signal data, including blood pressure, vital signs and so on, in the web browser of the PDA phone so radiologists can diagnose more effectively. Also, we acquired good results using an RW-6100 PDA phone used in the university hospital system of the Sinchon Severance Hospital in Korea.

    2016-05-01

    Heightened awareness about the radiation risks associated with CT imaging has increased patients' wishes to be informed of these risks, and has motivated efforts to reduce radiation dose and eliminate unnecessary imaging. However, many ordering providers, including emergency physicians, are ill prepared to have an informed discussion with patients about the cancer risks related to medical imaging. Radiologists, who generally have greater training in radiation biology and the risks of radiation, often do not have a face-to-face relationship with the patients who are being imaged. A collaborative approach between emergency physicians and radiologists is suggested to help explain these risks to patients who may have concerns about getting medical imaging. PMID:26647958

  13. An emergency packet forwarding scheme for V2V communication networks.

    PubMed

    Hoque, Faika; Kwon, Sungoh

    2014-01-01

    This paper proposes an effective warning message forwarding scheme for cooperative collision avoidance. In an emergency situation, an emergency-detecting vehicle warns the neighbor vehicles via an emergency warning message. Since the transmission range is limited, the warning message is broadcast in a multihop manner. Broadcast packets lead two challenges to forward the warning message in the vehicular network: redundancy of warning messages and competition with nonemergency transmissions. In this paper, we study and address the two major challenges to achieve low latency in delivery of the warning message. To reduce the intervehicle latency and end-to-end latency, which cause chain collisions, we propose a two-way intelligent broadcasting method with an adaptable distance-dependent backoff algorithm. Considering locations of vehicles, the proposed algorithm controls the broadcast of a warning message to reduce redundant EWM messages and adaptively chooses the contention window to compete with nonemergency transmission. Via simulations, we show that our proposed algorithm reduces the probability of rear-end crashes by 70% compared to previous algorithms by reducing the intervehicle delay. We also show that the end-to-end propagation delay of the warning message is reduced by 55%. PMID:25054181

    This paper proposes an effective warning message forwarding scheme for cooperative collision avoidance. In an emergency situation, an emergency-detecting vehicle warns the neighbor vehicles via an emergency warning message. Since the transmission range is limited, the warning message is broadcast in a multihop manner. Broadcast packets lead two challenges to forward the warning message in the vehicular network: redundancy of warning messages and competition with nonemergency transmissions. In this paper, we study and address the two major challenges to achieve low latency in delivery of the warning message. To reduce the intervehicle latency and end-to-end latency, which cause chain collisions, we propose a two-way intelligent broadcasting method with an adaptable distance-dependent backoff algorithm. Considering locations of vehicles, the proposed algorithm controls the broadcast of a warning message to reduce redundant EWM messages and adaptively chooses the contention window to compete with nonemergency transmission. Via simulations, we show that our proposed algorithm reduces the probability of rear-end crashes by 70% compared to previous algorithms by reducing the intervehicle delay. We also show that the end-to-end propagation delay of the warning message is reduced by 55%. PMID:25054181

    Some large regions of our interior oceans are losing oxygen both from the impacts of human uses of coastal margins and the impacts that climate change is having on ocean circulation. As oxygen minimum zones expand, impacts are especially noticed along the edges of continents. Ecosystems are being affected in ways that result in habitat compression or forced migrations. Looking into the future, we foresee large scale disruptions to habitat that, in some cases, will dramatically impact fish productivity. As waters become more hypoxic, energy fixed by marine plants will be less available to support higher trophic levels (e.g. fish and marine mammals). Communicating concern about hypoxia has its challenges: the word itself is poorly know to those on land who live in an oxygen-rich world. Thus, crucial factors in effective communication include illustrating: i) how many ocean animals live “on the edge”, ii) how ocean organisms respond to hypoxia iii) the long-term effects on ocean ecosystems and iv) causes and mitigation. For media that respond to visual stimulation, good graphics, evocative analogies and focussed examples are important.

    Policy and technical issues associated with the use of satellite communications for disaster mitigation and relief, sustainable development, education, and land mine detection were discussed at the Space Generation Forum (SGF), at UNISPACE-III. The youth perspective on this topic is being further developed at the Space Generation Summit (SGS), an event at World Space Congress (WSC) which shall unite international students and young professionals to develop a youth vision and strategy for the peaceful uses of space. SGS, endorsed by the United Nations, will take place from October 11-13th, during which the 200 delegates will discuss ongoing youth space activities, particularly those stemming from the UNISPACE-III/SGF and taken forward by the Space Generation Advisory Council. Delegates will address a variety of topics with the goal of devising new recommendations according to the theme, 'Accelerating Our Pace in Space'. The material presented here and in other technical sessions throughout WSC includes the findings of these discussions. In this paper, we present the work of the SGS delegates relating to Satellite communication and Global Information Infrastructure. This international team of young people has been working to support the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS) on their Action Teams for the implementation of disaster mitigation, planetary defense, sustainable development, and education recommendations from UNISPACE III. Results of work to date will be presented.

    An overview of NASA's Thin Route satellite telecommunication project is presented. Thin Route employs applications technology satellites (ATS) in place of more costly commercial multi- transponder telecommunications satellites. This system allows remote and underdeveloped areas to communicate with the outside world for purposes of obtaining medical assistance among other things. The system represents a substantial cost saving over commercial systems.

    New applications of information and communication technology (ICT) are shaping the way we understand and provide humanitarian medical assistance in situations of disaster, disease outbreak or conflict. Each new crisis appears to be accompanied by advancements in humanitarian technology, leading to significant improvements in the humanitarian aid sector. However, ICTs raise ethical questions that warrant attention. Focusing on the context of humanitarian medical assistance, we review key domains of ICT innovation. We then discuss ethical challenges and uncertainties associated with the development and application of new ICTs in humanitarian medical assistance, including avoiding harm, ensuring privacy and security, responding to inequalities, demonstrating respect, protecting relationships, and addressing expectations. In doing so, we emphasize the centrality of ethics in humanitarian ICT design, application and evaluation. PMID:27481835

    The purpose of this thesis is to describe the concept of broadcasting from satellites directly to the viewer equipped with a small, inexpensive receiving antenna, and the evolution of this technology as a means of commercial broadcast. Emphasis is placed on the problems of developing a regulatory framework for DBS by the Federal Communications Commission. The opposition of the existing broadcasters to the unregulated development of direct broadcast satellite (DBS) is explored in light of the possible effect that DBS may have on the economic base, audience, and advertising revenue of existing broadcasters. The information for this study was obtained from government documents, legal journals, books and the popular press. Two basic conclusions are drawn from this study: First, that the existing broadcasters have opposed the marketplace development of DBS, and second, that DBS does not pose as great a threat, at least in the near term, as the broadcasters fear.

  1. Content Characteristics Driving the Diffusion of Antismoking Messages: Implications for Cancer Prevention in the Emerging Public Communication Environment

    2013-01-01

    This study examined how content characteristics of antitobacco messages affect smokers’ selective exposure to and social sharing of those messages. Results from an experiment revealed that content features predicting smokers’ selection of antismoking messages are different from those predicting whether those messages are shared. Antismoking messages smokers tend to select are characterized by strong arguments (odds ratio = 2.02, P = .02) and positive sentiments (odds ratio = 3.08, P = .03). Once selected, the messages more likely to be retransmitted by smokers were those with novel arguments (B = .83, P = .002) and positive sentiments (B = 1.65, P = .005). This research adds to the literature about the content characteristics driving the social diffusion of antitobacco messages and contributes to our understanding of the role of persuasive messages about smoking cessation in the emerging public communication environment.

    Linguistic and cultural differences can impede comprehension among potential research participants during the informed consent process, but how researchers and IRBs respond to these challenges in practice is unclear. We conducted in-depth interviews with 15 researchers, research ethics committee (REC) chairs and members from 8 different countries with emerging economies, involved in HIV-related research sponsored by HIV Prevention Trials Network (HPTN), regarding the ethical and regulatory challenges they face in this regard. In the interviews, problems with translating study materials often arose as major concerns. Four sets of challenges were identified concerning linguistic and cultural translations of informed consent documents and other study materials, related to the: (1) context, (2) process, (3) content and (4) translation of these documents. Host country contextual issues included low literacy rates, education (e.g., documents may need to be written below 5th grade reading level), and experiences with research, and different views of written documentation. Certain terms and concepts may not exist in other languages, or have additional connotations that back translations do not always reveal. Challenges arise because of not only the content of word-for-word, literal translation, but the linguistic form of the language, such as tone (e.g., appropriate forms of politeness vs. legalese, seen as harsh), syntax, manner of questions posed, and the concept of the consent); and the contexts of use affect meaning. Problems also emerged in bilateral communications – US IRBs may misunderstand local practices, or communicate insufficiently the reasons for their decisions to foreign RECs. In sum, these data highlight several challenges that have received little, if any, attention in past literature on translation of informed consent and study materials, and have crucial implications for improving practice, education, research and policy, suggesting several strategies

    Abstract The predominant circulating HIV-1 strains in South America are subtype B and B/F recombinants with different distributions among countries. However, the emergence of other subtypes is a matter of concern and needs continuous monitoring. We identified three different A/G recombinants in Argentina, two of them in vertically infected children from unlinked mothers and one in an adult female. HIV-1 pol sequences from the children showed novel A/G recombination patterns and no phylogenetic relationship with previously reported South American A/G sequences. The third A/G recombinant was a CRF06_cpx with African origin. The detection of new or unusual subtypes is important to avoid false-negative PCR HIV-1 early diagnosis due to detection failures and for future vaccine development. PMID:25417788

    In situ electromagnetic (EM) radio frequency (RF) exposure to base stations of emerging wireless technologies is assessed at 311 locations, 68 indoor and 243 outdoor, spread over 35 areas in three European countries (Belgium, The Netherlands, and Sweden) by performing narrowband spectrum analyzer measurements. The locations are selected to characterize six different environmental categories (rural, residential, urban, suburban, office, and industrial). The maximal total field value was measured in a residential environment and equal to 3.9 V m(-1), mainly due to GSM900 signals. Exposure ratios for maximal electric field values, with respect to ICNIRP reference levels, range from 0.5% (WiMAX) to 9.3% (GSM900) for the 311 measurement locations. Exposure ratios for total field values vary from 3.1% for rural environments to 9.4% for residential environments. Exposures are lognormally distributed and are the lowest in rural environments and the highest in urban environments. Highest median exposures were obtained in urban environments (0.74 V m(-1)), followed by office (0.51 V m(-1)), industrial (0.49 V m(-1)), suburban (0.46 V m(-1)), residential (0.40 V m(-1)), and rural (0.09 V m(-1)) environments. The average contribution to the total electric field is more than 60% for GSM. Except for the rural environment, average contributions of UMTS-HSPA are more than 3%. Contributions of the emerging technologies LTE and WiMAX are on average less than 1%. The dominating outdoor source is GSM900 (95 percentile of 1.9 V m(-1)), indoor DECT dominates (95 percentile of 1.5 V m(-1)). PMID:22217589

    'Connected' is the name of the national advanced communication skills training programme developed in 2008 for cancer care professionals in the NHS. A 3-day training course combining didactic and experiential learning elements is run by two facilitators with course participants expected to engage fully in simulated consultations with trained actors. In 2011, and as a result of participant feedback on the length of the course and increasing pressures on budgets and clinical time, the Connected team developed and piloted an alternative 2-day training course. Before its roll-out in 2012, Birmingham City University was commissioned to evaluate the effectiveness and quality of the 2-day course vis-à-vis the 'traditional' 3-day one. This article is written by the two evaluators and it discusses some of the issues that emerged during the evaluation. We broadly grouped these issues into two overlapping categories: the mandatory nature of the course and the different professional background and seniority of participants. In our discussion we consider the implications these issues have for communication skills training policy and practice and put forward suggestions for further research. PMID:24373021

    2013-01-01

    Intermolecular interactions within living organisms have been found to occur not as individual independent events but as a part of a collective array of interconnected events. The problem of the emergence of this collective dynamics and of the correlated biocommunication therefore arises. In the present paper we review the proposals given within the paradigm of modern molecular biology and those given by some holistic approaches to biology. In recent times, the collective behavior of ensembles of microscopic units (atoms/molecules) has been addressed in the conceptual framework of Quantum Field Theory. The possibility of producing physical states where all the components of the ensemble move in unison has been recognized. In such cases, electromagnetic fields trapped within the ensemble appear. In the present paper we present a scheme based on Quantum Field Theory where molecules are able to move in phase-correlated unison among them and with a self-produced electromagnetic field. Experimental corroboration of this scheme is presented. Some consequences for future biological developments are discussed. PMID:24288611

Here we describe the communication strategy developed for the Mont de La Saxe case study, a large rockslide threatening La Palud and Entrèves hamlets in the Courmayeur municipality (Aosta Valley, Italy). Starting from the definition of actions and needs of the Landslide Management Team, including scientists, technicians, civil protection operators, decision makers, and politicians, we show that sharing and disseminating ad hoc information simplifies the understanding of the landslide evolution, as well as the correct communication of the level of criticality.

    The CDC released revised HIV testing guidelines in 2006 recommending routine, opt-out HIV testing in acute care settings including emergency departments (ED). Patient attitudes have been cited as a barrier to implementation of routine HIV testing in the ED. We assessed patients' perceptions of HIV testing in the ED through a contextual qualitative approach. The study was conducted during a 72-h period. All adults presenting to the ED without life-threatening trauma or psychiatric crisis completed a standardized questionnaire. The questionnaire explored HIV testing history, knowledge of testing resources, and qualitative items addressing participant perceptions about advantages and disadvantages to ED testing. After completion of the interview, participants were offered a free, confidential, rapid HIV test. Among 329 eligible individuals approached, 288 (87.5%) completed the initial interview. Participants overwhelmingly (n=247, 85.8%) reported support for testing and identified increased knowledge (41%), prevention (12.5%), convenience (11.8%), and treatment (4.9%) among the advantages. Fear and denial about one's HIV status, reported by <5% of patients, were identified as the most significant barriers to ED testing. Bivariate analysis determined race and ethnicity differences between individuals completing the interview and those who refused (p<0.05). Among individuals consenting for testing (n=186, 64.6%), no positives were detected. Most patients support HIV testing in the ED, noting knowledge of status, prevention, convenience, and linkage to early treatment as distinct advantages. These data are of particular benefit to decision makers considering the addition of routine HIV testing in EDs. PMID:21790474

    Published information about career options and the core competencies necessary for health communication professionals (HCPs) is limited. Although the number of graduate programs in health communication continues to grow, no formal assessment of the success of this type of training has been conducted. The current study presents the results of an evaluation of the Master's Program in Health Communication offered collaboratively by Emerson College and the Tufts University School of Medicine. The program was one of the first of its kind and has graduated more health communication students than any other in the United States. To conduct the assessment of the program, the two schools collaborated on the development of an on-line survey for the alumni. Of the 131 graduates eligible to participate, 106 completed the survey. The survey yielded detailed information on the following: (1) career options for individuals with master's degrees in health communication; (2) value of graduate coursework for developing competencies in health communication; (3) salary expectations for individuals with graduate degrees in health communication; and (4) emerging trends in the field. These findings have important implications for the development of new programs and the refinement of existing ones in health communication. PMID:15764441

    This study proposed the use of assistive technology (AT) to promote communication and leisure opportunities by three children with traumatic brain injury (TBI). Furthermore, it assessed the effects of such technology on the indices of positive participation and provided a social validation procedure. Three children emerged from a minimal conscious state and presenting extensive motor disabilities were involved. The intervention program allowed the participants to request and to choice preferred items independently and to perform literacy through a keyboard emulator. A multiple probe design across behaviors with post-intervention check was employed. Outcome measures were correct requests, understandable words, intervals with positive participation, and scores of social validation assessment. Request and choice behaviors and literacy improved significantly during intervention phases. During post-intervention check, all participants consolidated their performance. Moreover, indices of positive participation increased during intervention phases. Scores of social validation assessment showed that the combination of both behaviors was preferable to the same considered separately. AT program showed to be suitable for promoting constructive engagement and literacy behaviors by children with TBI. Future research is needed to generalize this data to a larger sample and to develop new technology for people with different levels of disabilities due to TBI. PMID:25077461

    The Sustainable Development Goal (SDG) maternal mortality target risks being underachieved like its Millennium Development Goal (MDG) predecessor. The MDG skilled birth attendant (SBA) strategy proved inadequate to end preventable maternal deaths for the millions of rural women living in resource-constrained settings. This equity gap has been successfully addressed by integrating a community-based emergency obstetric care strategy into the intrapartum care SBA delivery strategy in a large scale, northern Nigerian health systems strengthening project. The Community Communication Emergency Referral (CCER) strategy catalyzes community capacity for timely evacuations to emergency obstetric care facilities instead of promoting SBA deliveries in environments where SBA availability and accessibility will remain inadequate for the near and medium term. Community Communication is an innovative, efficient, equitable, and culturally appropriate community mobilization approach that empowers low- and nonliterate community members to become the communicators. For the CCER strategy, this community mobilization approach was used to establish and maintain emergency maternal care support structures. Public health evidence demonstrates the success of integrating the CCER strategy into the SBA strategy and the practicability of this combined strategy at scale. In intervention sites, the maternal mortality ratio reduced by 16.8% from extremely high levels within 4 years. Significantly, the CCER strategy contributed to saving one-third of the lives saved in the project sites, thereby maximizing the effectiveness of the SBAs and upgraded emergency obstetric care facilities. Pre- and postimplementation Knowledge, Attitude, and Practice Survey results and qualitative assessments support the CCER theory of change. This theory of change rests on a set of implementation steps that rely on three innovative components: Community Communication, Rapid Imitation Practice, and CCER support

    Making decisions for a patient affected by sudden devastating illness or injury traumatizes a patient's family and loved ones. Even in the absence of an emergency, surrogates making end-of-life treatment decisions may experience negative emotional effects. Helping surrogates with these end-of-life decisions under emergent conditions requires the emergency physician (EP) to be clear, making medical recommendations with sensitivity. This model for emergency department (ED) end-of-life communications after acute devastating events comprises the following steps: 1) determine the patient's decision-making capacity; 2) identify the legal surrogate; 3) elicit patient values as expressed in completed advance directives; 4) determine patient/surrogate understanding of the life-limiting event and expectant treatment goals; 5) convey physician understanding of the event, including prognosis, treatment options, and recommendation; 6) share decisions regarding withdrawing or withholding of resuscitative efforts, using available resources and considering options for organ donation; and 7) revise treatment goals as needed. Emergency physicians should break bad news compassionately, yet sufficiently, so that surrogate and family understand both the gravity of the situation and the lack of long-term benefit of continued life-sustaining interventions. EPs should also help the surrogate and family understand that palliative care addresses comfort needs of the patient including adequate treatment for pain, dyspnea, or anxiety. Part I of this communications model reviews determination of decision-making capacity, surrogacy laws, and advance directives, including legal definitions and application of these steps; Part II (which will appear in a future issue of AEM) covers communication moving from resuscitative to end-of-life and palliative treatment. EPs should recognize acute devastating illness or injuries, when appropriate, as opportunities to initiate end-of-life discussions and to

    2014-01-01

    Background Videoconferencing on mobile phones may enhance communication, but knowledge on its quality in various situations is needed before it can be used in medical emergencies. Mobile phones automatically activate loudspeaker functionality during videoconferencing, making calls particularly vulnerable to background noise. The aim of this study was to investigate if videoconferencing can be used between lay bystanders and Emergency Medical Dispatch (EMD) operators for initial emergency calls during medical emergencies, under suboptimal sound and light conditions. Methods Videoconferencing was tested between 90 volunteers and an emergency medical dispatcher in a standardized scenario of a medical emergency. Three different environments were used for the trials: indoors with moderate background noise, outdoors with daylight and much background noise, and outdoors during nighttime with little background noise. Thirty participants were recruited for each of the three locations. After informed consent, each participant was asked to use a video mobile phone to communicate with an EMD operator. During the video call the EMD operator gave instructions for tasks to be performed by the participant. The video quality from the caller to the EMD was evaluated by the EMD operator and rated on a five step scale ranging from "not able to see" to "good video quality". Sound quality between participants and EMD operators was assessed by a method developed for this trial. Kruskal – Wallis and Chi-square tests were used for statistical analysis. Results Video quality was significantly different between the groups (p <0.001), and the nighttime group had lower video quality. For most sessions in the nighttime group it was still possible to see actions done at the simulated emergency site. All participants were able to perform their tasks according to the instructions given by dispatchers, although with a need for more repetitions during sessions with much background noise. No calls

  1. Predicting a prior for Planck

    SciTech Connect

    The quantum state of the universe combined with the structure of the landscape potential implies a prior that specifies predictions for observations. We compute the prior for CMB related observables given by the no-boundary wave function (NBWF) in a landscape model that includes a range of inflationary patches representative of relatively simple single-field models. In this landscape the NBWF predicts our classical cosmological background emerges from a region of eternal inflation associated with a plateau-like potential. The spectra of primordial fluctuations on observable scales are characteristic of concave potentials, in excellent agreement with the Planck data. By contrast, alternative theories of initial conditions that strongly favor inflation at high values of the potential are disfavored by observations in this landscape.

    Objectives Studies have shown that differences among individuals and social groups in accessing and using information on health and specific threats have an impact on their knowledge and behaviors. These differences, characterized as communication inequalities, may hamper the strength of a society's response to a public health emergency. Such inequalities not only make vulnerable populations subject to a disproportionate burden of adversity, but also compromise the public health system's efforts to prevent and respond to pandemic influenza outbreaks. We investigated the effect of socioeconomic status (SES) and health communication behaviors (including barriers) on people's knowledge and misconceptions about pandemic influenza A(H1N1) (pH1N1) and adoption of prevention behaviors. Methods The data for this study came from a survey of 1,569 respondents drawn from a nationally representative sample of American adults during pH1N1. We conducted logistic regression analyses when appropriate. Results We found that (1) SES has a significant association with barriers to information access and processing, levels of pH1N1-related knowledge, and misconceptions; (2) levels of pH1N1-related knowledge are associated positively with the adoption of recommended prevention measures and negatively with the adoption of incorrect protective behaviors; and (3) people with higher SES, higher news exposure, and higher levels of pH1N1-related knowledge, as well as those who actively seek information, are less likely than their counterparts to adopt incorrect prevention behaviors. Conclusion Strategic public health communication efforts in public health preparedness and during emergencies should take into account potential communication inequalities and develop campaigns that reach across different social groups.

  3. Communicating and managing change during extreme weather events: promising practices for responding to urgent and emergent climate threats.

    Tinker, Tim L

    2013-01-01

    Large-scale weather events in the USA such as hurricanes Sandy, Isaac and Katrina challenge traditional approaches to change communication and management (CCM) before during and after crises. A major challenge (as well as opportunity) is addressing change from the 'whole-community' perspective affecting a spectrum of people, policies, processes, behaviours and outcomes. When CCM is used effectively, one of its fundamental advantages is creating a sense of urgency. This paper looks at optimising communication during extreme weather events, engaging stakeholders, harnessing the power of social media and change, and correlating organisational and individual behaviours and actions. The strategic blend of change management and crisis communication strategies and tactics in CCM is a central feature in the response to the full range of extreme weather scenarios. PMID:23835423

    The proposal for an integrated national emergency number for India is garnering a lot of enthusiasm and stimulating debate. This ambitious project has a two-part paradigm shift to set in; the first being the integration into a single number and the infrastructure required for setting up and operating this number such that a call can be received and identified. The second is the submerged part of the iceberg: That of the ability to respond to a call and deliver the appropriate emergency service. The first part is more technical and has potential precedents like the 911 phone hotline, for example, to emulate. The main premise of this paper is that the second part is a rather subjective exercise largely determined by the realities of existing public infrastructure in a specific geographical area with respect to emergency services management, especially medical care. Consequently, we highlight the key areas of both precall preparedness and postcall execution that need to be reviewed prior to going live with an integrated number on a national scale. PMID:23960382

    This study presents a systematic comparison of two alternative measures of citizens' perceptions of risks and benefits of emerging technologies. By focusing on two specific issues (nanotechnology and biofuels), we derive several insights for the measurement of public views of science. Most importantly, our analyses reveal that relying on global, single-item measures may lead to invalid inferences regarding external influences on public perceptions, particularly those related to cognitive schema and media use. Beyond these methodological implications, this analysis suggests several reasons why researchers in the area of public attitudes toward science must revisit notions of measurement in order to accurately inform the general public, policymakers, scientists, and journalists about trends in public opinion toward emerging technologies.

    2014-05-01

    Terminally ill patients can have unexpected, enigmatic, and profound cognitive shifts that significantly alter their perception of themselves, thereby eliminating their fear of death and dying. However, there are no systematic studies into these remarkable yet ineffable transcendence experiences. They therefore remain easily overlooked or viewed as isolated anomalies and therefore excluded from quality-of-life patient considerations. We use a multimodal methodology for identifying the prevalence and thematic properties of complex emergent metaphors patients use to report these experiences. Although previous research has pioneered the importance of understanding conventional or primary metaphors at the end of life, our findings indicate the considerable potential of more complex metaphors for reducing barriers to effective communication in palliative care.

    1988-06-01

    In two surveys of headaches it was noted that their incidence had increased significantly within 48 h prior to earthquakes from an incidence of 17% to 58% in the first survey using correlated samples and from 20.4% to 44% in the second survey using independent samples. It is suggested that an increase in positive air ions from rock compression may trigger head pain via a decrease in brain levels of the neurotransmitter serotonin. The findings are presented as preliminary, with the hope of generating further research efforts in areas more prone to earthquakes.

    Increasing evidence over the past decade suggests that vision is not simply a passive, feed-forward process in which cortical areas relay progressively more abstract information to those higher up in the visual hierarchy, but rather an inferential process with top-down processes actively guiding and shaping perception. However, one major question that persists is whether such processes can be influenced by unconsciously perceived stimuli. Recent psychophysics and neuroimaging studies have revealed that while consciously perceived stimuli elicit stronger responses in higher visual and frontoparietal areas than those that fail to reach conscious awareness, the latter can still drive high-level brain and behavioral responses. We investigated whether unconscious processing of a masked natural image could facilitate subsequent conscious recognition of its degraded counterpart (a black-and-white “Mooney” image) presented many seconds later. We found that this is indeed the case, suggesting that conscious vision may be influenced by priors established by unconscious processing of a fleeting image.

  16. Impact of Prior Seasonal H3N2 Influenza Vaccination or Infection on Protection and Transmission of Emerging Variants of Influenza A(H3N2)v Virus in Ferrets

    PubMed Central

    Houser, Katherine V.; Pearce, Melissa B.; Katz, Jacqueline M.

    2013-01-01

    Influenza H3N2 A viruses continue to circulate in swine and occasionally infect humans, resulting in outbreaks of variant influenza H3N2 [A(H3N2)v] virus. It has been previously demonstrated in ferrets that A(H3N2)v viruses transmit as efficiently as seasonal influenza viruses, raising concern over the pandemic potential of these viruses. However, A(H3N2)v viruses have not acquired the ability to transmit efficiently among humans, which may be due in part to existing cross-reactive immunity to A(H3N2)v viruses. Although current seasonal H3N2 and A(H3N2)v viruses are antigenically distinct from one another, historical H3N2 viruses have some antigenic similarity to A(H3N2)v viruses and previous exposure to these viruses may provide a measure of immune protection sufficient to dampen A(H3N2)v virus transmission. Here, we evaluated whether prior seasonal H3N2 influenza virus vaccination or infection affects virus replication and transmission of A(H3N2)v virus in the ferret animal model. We found that the seasonal trivalent inactivated influenza virus vaccine (TIV) or a monovalent vaccine prepared from an antigenically related 1992 seasonal influenza H3N2 (A/Beijing/32/1992) virus failed to substantially reduce A(H3N2)v (A/Indiana/08/2011) virus shedding and subsequent transmission to naive hosts. Conversely, ferrets primed by seasonal H3N2 virus infection displayed reduced A(H3N2)v virus shedding following challenge, which blunted transmission to naive ferrets. A higher level of specific IgG and IgA antibody titers detected among infected versus vaccinated ferrets was associated with the degree of protection offered by seasonal H3N2 virus infection. The data demonstrate in ferrets that the efficiency of A(H3N2)v transmission is disrupted by preexisting immunity induced by seasonal H3N2 virus infection. PMID:24089569

    Objectives (1) To examine changes in women's awareness and utilisation of reproductive healthcare services in emergency settings following provision of interpersonal communication (IPC) and mass education campaigns, and (2) to describe factors associated with reproductive healthcare service use in internally displaced person (IDP) camps. Setting Three camps containing 88 984 IDPs in Darfur, Sudan. Participants 640 women aged 15−49 who had experienced pregnancy in the camp during the previous 2 years were enrolled in each of two independent cross-sectional surveys 26 months apart. Interventions IPC and mass education campaigns where community health workers disseminated information by home/shelter visits, clinic sessions, public meetings and other means to raise awareness and promote reproductive healthcare service use. Primary outcome measures Awareness of the existence of antenatal care (ANC) and tetanus toxoid (TT) vaccination services, reception of ANC and TT vaccination, place of delivery and use of postnatal care (PNC). Results The percentage of women who received home visits, and attended in-clinic sessions and public meetings increased from 61.6% to 86.7%, from 43.0% to 68.8%, and from 3.8% to 39.8%, respectively, between the initial and follow-up surveys. More women were aware of ANC (OR 18.6, 95% CI 13.1 to 26.5) and TT vaccination (OR 3.2, 95% CI 2.4 to 4.4) in the follow-up than the initial survey, after multivariable adjustment. More women received ≥3 ANC visits (OR 8.8, 95% CI 6.4 to 12.0) and ≥3 doses of TT (OR 2.5, 95% CI 1.9 to 3.3), delivered at a healthcare facility (OR 5.4, 95% CI 4.0 to 7.4) and received a PNC visit (OR 5.5, 95% CI 4.0 to 7.7) in the follow-up than in the initial survey, after multivariable adjustment. Conclusions Awareness about and utilisation of reproductive healthcare services were higher in the follow-up survey. An integrated IPC and mass education campaign is effective for improving women's reproductive health

  18. Infodemiology and Infoveillance: Framework for an Emerging Set of Public Health Informatics Methods to Analyze Search, Communication and Publication Behavior on the Internet

    2009-01-01

    Infodemiology can be defined as the science of distribution and determinants of information in an electronic medium, specifically the Internet, or in a population, with the ultimate aim to inform public health and public policy. Infodemiology data can be collected and analyzed in near real time. Examples for infodemiology applications include: the analysis of queries from Internet search engines to predict disease outbreaks (eg. influenza); monitoring peoples' status updates on microblogs such as Twitter for syndromic surveillance; detecting and quantifying disparities in health information availability; identifying and monitoring of public health relevant publications on the Internet (eg. anti-vaccination sites, but also news articles or expert-curated outbreak reports); automated tools to measure information diffusion and knowledge translation, and tracking the effectiveness of health marketing campaigns. Moreover, analyzing how people search and navigate the Internet for health-related information, as well as how they communicate and share this information, can provide valuable insights into health-related behavior of populations. Seven years after the infodemiology concept was first introduced, this paper revisits the emerging fields of infodemiology and infoveillance and proposes an expanded framework, introducing some basic metrics such as information prevalence, concept occurrence ratios, and information incidence. The framework distinguishes supply-based applications (analyzing what is being published on the Internet, eg. on Web sites, newsgroups, blogs, microblogs and social media) from demand-based methods (search and navigation behavior), and further distinguishes passive from active infoveillance methods. Infodemiology metrics follow population health relevant events or predict them. Thus, these metrics and methods are potentially useful for public health practice and research, and should be further developed and standardized. PMID:19329408

    2003-10-01

    We have performed detailed numerical 3-d simulations of the interaction of buoyantly ascending twisted magnetic flux ropes and solar-like stratified convection (with surface cells similar to solar supergranules in size). Results are presented for three different cases -- corresponding to different amounts of initial field line twist -- that represents fundamentally different types of instabilities: the magnetic Rayleigh-Taylor instability in which case the flux rope disrupts and network patches are formed at surface cell boundaries; the kink instability that has been proposed as a mechanism for forming tightly packed δ-type spots; a stable flux rope where neither of the former instabilities arise, and the behavior of which is similar to classical text book flux tubes, except from a flux-loss due to the advective action of the convective flows. The simulations thus support the idea that the magnetic flux observed at the surface in bipolar regions are smaller, ceteris paribus, than that of the dynamo generated flux ropes near the bottom of the convection zone.

    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

  6. Speak no evil: The promotional heritage of nuclear risk communication

    SciTech Connect

    Gwin, L.

    1990-01-01

    Louis Gwin addresses the critically important problem of nuclear risk communication. His research suggests that while an orderly evacuation of the population actually at risk may be workable in theory, the more likely occurrence is widespread panic and gridlock. Gwin's research suggests that existing programs of nuclear risk communication actually make this problem worse. He found that those who had received no prior information on what to do in an emergency were significantly more likely to do the right thing (e.g., await further instructions) than those who had received instructions. With utilities themselves retaining the ultimate responsibility for developing communication programs, it is not surprising that they have been reluctant; to issue instructions on what to do in the event of a nuclear accident is to acknowledge that such accidents can and do occur. Gwin makes no attempt to protray the nuclear industry as purposefully dishonest or evil. The bottom line is that programs that combine the communication of emergency plans with a latent desire to reassure the public fail in their primary purpose. As Gwin observes the key issue is one of trust. People see such communications as little more than propaganda put out by industry for its own purposes and do not trust the utilities to tell them what to do in the event of an accident. It will be every man for himself, with potentially disastrous consequences. How do we restore trust in nuclear risk communications Gwin offers a number of valuable suggestions such as placing communication responsibility in state or local agencies or in FEMA, and to ensure some form of public participation in the development and communication of emergency plans. This is an excellent study of an important and timely subject. It provides a much needed picture of just how badly our plans are likely to work in the next nuclear emergency. Gwin's warning should be heeded by policymakers now, while there is still time.

  7. An implementation-independent threat model for group communications

    Hester, Jason; Yurcik, William; Campbell, Roy

    2006-04-01

    The importance of group communications and the need to efficiently and reliably support it across a network is an issue of growing importance for the next decade. New group communication services are emerging such as multimedia conferencing/groupware, distributed interactive simulations, sensor fusion systems, command and control centers, and network-centric military applications. While a succession of point-to-point unicast routes could provide group communications, this approach is inherently inefficient and unlikely to support the increased resource requirements of these new services. There is the lack of a comprehensive process to designing security into group communications schemes. Designing such protection for group communications is best done by utilizing proactive system engineering rather than reacting with ad hoc countermeasures to the latest attack du jour. Threat modeling is the foundation for secure system engineering processes because it organizes system threats and vulnerabilities into general classes so they can be addressed with known protection techniques. Although there has been prior work on threat modeling primarily for software applications, however, to our knowledge this is the first attempt at implementation-independent threat modeling for group communications. We discuss protection challenges unique to group communications and propose a process to create a threat model for group communication systems independent of underlying implementation based on classical security principles (Confidentiality, Integrity, Availability, Authentication, or CIAA). It is our hope that this work will lead to better designs for protection solutions against threats to group communication systems.

    "Half the world is composed of people who have something to say and can't, and the other half who have nothing to say and keep on saying it." - Robert Frost In this age of digital soap boxes and half-truths, the importance of geoscientists as communicators cannot be underestimated, nor has there been a more important time for researchers to stand up and demand to be heard. So why is there still such an overwhelming public perception that scientists are poor communicators, and what can we do to change this? In this work I will present an overview of a number of successful initiatives that have been developed at Manchester Metropolitan University, and beyond, to ensure that science is communicated to a large variety of people, from policy makers to members of the local community. I will also present an overview of the emerging field of Science Communication, how it has changed in the past few decades from a one-way diatribe to a two-way discussion, and how this represents a possible new direction and career path for geoscientists. Anne Roe, the noted American psychologist, told us, "nothing in science has any value to society if it is not communicated." As geoscientists, we have a professional and moral obligation to ensure that we not only research the facts, but that we also present them in an informative and engaging manner, so that the rest of humanity can benefit from the fruits of our labour.
