    Case reports in medical literature suggest that the atypical antipsychotic quetiapine, a medication not previously considered to have abuse potential, is now being subject to misuse and abuse (MUA; ie, taken when not prescribed for them or used in a way other than instructed by their health professional). Here we present systematic, nationally representative data from the 2005 to 2011 Drug Abuse Warning Network (DAWN) for prevalence of emergency department (ED) visits among the U.S. general population involving quetiapine and related to MUA, suicide attempts, and adverse reactions. Nationally, quetiapine-related ED visits increased 90% between 2005 and 2011, from 35,581 ED visits to 67,497. DAWN data indicate that when used without medical supervision for recreational/self-medication purposes, quetiapine poses health risks for its users, especially among polydrug users and women. These findings suggest that the medical and public health communities should increase vigilance concerning this drug and its potential for MUA. PMID:26056465

    Meteorological monitoring system (MMS) computer network tracks weather conditions and issues warnings when weather hazards are about to occur. Receives data from such meteorological instruments as wind sensors on towers and lightning detectors, and compares data with weather restrictions specified for outdoor activities. If weather violates restriction, network generates audible and visible alarms to alert people involved in activity. Also displays weather and toxic diffusion data and disseminates weather forecasts, advisories, and warnings to workstations.

    Licorice extract has always been recognized as a sweetener and a thirst quencher. Its nutritive value is overrated by many who consume significant amounts and are prone to complications. Glycyrrhetic acid, the active metabolite in licorice, inhibits the enzyme 11-ß-hydroxysteroid dehydrogenase enzyme type 2 with a resultant cortisol-induced mineralocorticoid effect and the tendency towards the elevation of sodium and reduction of potassium levels. This aldosterone-like action is the fundamental basis for understanding its health benefits and the wide spectrum of adverse effects. Herein, we present a comprehensive review of licorice along with the reported complications related to excess intake. Despite its apparent use in a few clinical scenarios, the daily consumption of licorice is never justified because its benefits are minor compared to the adverse outcomes of chronic consumption. The review highlights the importance of investigating the dietary habits and herbal remedies which are being used worldwide on cultural and habitual bases rather than reliable scientific evidence. Licorice is a US Food and Drug Administration (FDA) approved food supplement used in many products without precise regulations to prevent toxicity. Increased awareness among the public is required through TV commercials, newspapers, internet sites, magazines and product labels regarding the upper limit of ingestion and health hazards associated with excess intake. We hope that this review will serve as a warning message that should be transmitted from physicians to patients to avoid excessive licorice intake as well as a message to the FDA to start regulating the use of this substance.

    The FEWS NET mission is to identify potentially food-insecure conditions early through the provision of timely and analytical hazard and vulnerability information. U.S. Government decision-makers act on this information to authorize mitigation and response activities. The U.S. Geological Survey (USGS) FEWS NET provides tools and data for monitoring and forecasting the incidence of drought and flooding to identify shocks to the food supply system that could lead to famine. Historically focused on Africa, the scope of the network has expanded to be global coverage. FEWS NET implementing partners include the USGS, National Aeronautics and Space Administration (NASA), National Oceanic and Atmospheric Administration (NOAA), United States Agency for International Development (USAID), United States Department of Agriculture (USDA), and Chemonics International.

It also sets out to overcome problems of insufficient node density, which typically affects present existing early warning systems, by having the SOSEWIN seismological sensing units being comprised of low-cost components (generally bought "off-the-shelf"), with each unit initially costing 100's of Euros, in contrast to 1,000's to 10,000's for standard seismological stations. The reduced sensitivity of the new sensing units arising from the use of lower-cost components will be compensated by the network's density, which in the future is expected to number 100's to 1000's over areas served currently by the order of 10's of standard stations. The robustness, independence of infrastructure, spontaneous extensibility due to a self-healing/self-organizing character in the case of removing/failing or adding sensors makes SOSEWIN potentially useful for various use cases, e.g. monitoring of building structures or seismic microzonation. Nevertheless its main purpose is the earthquake early warning, for which reason the ground motion is continuously monitored by conventional accelerometers (3-component). It uses SEEDLink to store and provide access to the sensor data. SOSEWIN considers also the needs of earthquake task forces, which want to set-up a temporary seismic network rapidly and with light-weighted stations to record after-shocks. The wireless and self-organising character of this sensor network should be of great value

Based on this, the network itself decides whether an event is detected through cooperating stations. SEEDLink is used to store and provide access to the sensor data. Experiences and selected experiment results with the SOSEWIN-prototype installation in the Ataköy district of Istanbul (Turkey) are presented. SOSEWIN considers also the needs of earthquake task forces, which want to set-up a temporary seismic network rapidly and with light-weighted stations to record after-shocks.

    2013-11-01

    The financial crisis clearly illustrated the importance of characterizing the level of `systemic' risk associated with an entire credit network, rather than with single institutions. However, the interplay between financial distress and topological changes is still poorly understood. Here we analyze the quarterly interbank exposures among Dutch banks over the period 1998-2008, ending with the crisis. After controlling for the link density, many topological properties display an abrupt change in 2008, providing a clear - but unpredictable - signature of the crisis. By contrast, if the heterogeneity of banks' connectivity is controlled for, the same properties show a gradual transition to the crisis, starting in 2005 and preceded by an even earlier period during which anomalous debt loops could have led to the underestimation of counter-party risk. These early-warning signals are undetectable if the network is reconstructed from partial bank-specific data, as routinely done. We discuss important implications for bank regulatory policies.

    2013-01-01

    Individual evacuation decisions are often characterized by the influence of one's social network, referred to as informal warning network. In this article, a threshold model of social contagion, originally introduced in the network science literature, is proposed to characterize this social influence in the evacuation decision-making process, in particular the timing of evacuation decision. Simulation models are developed to investigate the effects of community mixing patterns and the strength of ties on timing of evacuation decision.

    It is of great significance to research the early warning system for large-scale network security incidents. It can improve the network system's emergency response capabilities, alleviate the cyber attacks' damage, and strengthen the system's counterattack ability. A comprehensive early warning system is presented in this paper, which combines active measurement and anomaly detection. The key visualization algorithm and technology of the system are mainly discussed. The large-scale network system's plane visualization is realized based on the divide and conquer thought. First, the topology of the large-scale network is divided into some small-scale networks by the MLkP/CR algorithm. Second, the sub graph plane visualization algorithm is applied to each small-scale network. Finally, the small-scale networks' topologies are combined into a topology based on the automatic distribution algorithm of force analysis. As the algorithm transforms the large-scale network topology plane visualization problem into a series of small-scale network topology plane visualization and distribution problems, it has higher parallelism and is able to handle the display of ultra-large-scale network topology.

    Abstract Problem On 6 February 2013, an 8.0 magnitude earthquake generated a tsunami that struck the Santa Cruz Islands, Solomon Islands, killing 10 people and displacing over 4700. Approach A post-disaster assessment of the risk of epidemic disease transmission recommended the implementation of an early warning alert and response network (EWARN) to rapidly detect, assess and respond to potential outbreaks in the aftermath of the tsunami. Local setting Almost 40% of the Santa Cruz Islands’ population were displaced by the disaster, and living in cramped temporary camps with poor or absent sanitation facilities and insufficient access to clean water. There was no early warning disease surveillance system. Relevant changes By 25 February, an EWARN was operational in five health facilities that served 90% of the displaced population. Eight priority diseases or syndromes were reported weekly; unexpected health events were reported immediately. Between 25 February and 19 May, 1177 target diseases or syndrome cases were reported. Seven alerts were investigated. No sustained transmission or epidemics were identified. Reporting compliance was 85%. The EWARN was then transitioned to the routine four-syndrome early warning disease surveillance system. Lesson learnt It was necessary to conduct a detailed assessment to evaluate the risk and potential impact of serious infectious disease outbreaks, to assess whether and how enhanced early warning disease surveillance should be implemented. Local capacities and available resources should be considered in planning EWARN implementation. An EWARN can be an opportunity to establish or strengthen early warning disease surveillance capabilities. PMID:25378746

    Large magnitude earthquakes in urban environments continue to kill and injure tens to hundreds of thousands of people, inflicting lasting societal and economic disasters. Earthquake early warning (EEW) provides seconds to minutes of warning, allowing people to move to safe zones and automated slowdown and shutdown of transit and other machinery. The handful of EEW systems operating around the world use traditional seismic and geodetic networks that exist only in a few nations. Smartphones are much more prevalent than traditional networks and contain accelerometers that can also be used to detect earthquakes. We report on the development of a new type of seismic system, MyShake, that harnesses personal/private smartphone sensors to collect data and analyze earthquakes. We show that smartphones can record magnitude 5 earthquakes at distances of 10 km or less and develop an on-phone detection capability to separate earthquakes from other everyday shakes. Our proof-of-concept system then collects earthquake data at a central site where a network detection algorithm confirms that an earthquake is under way and estimates the location and magnitude in real time. This information can then be used to issue an alert of forthcoming ground shaking. MyShake could be used to enhance EEW in regions with traditional networks and could provide the only EEW capability in regions without. In addition, the seismic waveforms recorded could be used to deliver rapid microseism maps, study impacts on buildings, and possibly image shallow earth structure and earthquake rupture kinematics.

    The main seismic hazard in western Canada is associated with the subduction of the Juan de Fuca plate under the North American continent. It threatens the major population centres of Vancouver and Victoria but also communities along the west coast of Vancouver Island, which face an additional threat from any earthquake-generated tsunami. WARN is a project of Ocean Networks Canada (ONC), a not-for-profit organization that manages several ocean observatories on behalf of the University of Victoria. WARN integrates an array of off-shore and on-shore sensors, both strong motion seismometers and ocean bottom pressure recorders, into a real-time network that is capable of detecting and classifying the early phases of an earthquake rupture as well as waves generated by a local or distant tsunami source. All of WARN's instruments perform complex signal processing tasks on site, on-line and in real time. For earthquakes, WARN's software receives event reports and waveform parameters from off-shore and on-shore strong motion seismometers and associates them with an epicentre and an average magnitude based on their respective empirical relationships. A client application computes the local impact time and expected severity in terms of Modified Mercalli Intensity from its own location in relation the reported epicentre, origin time and magnitude. Event reports from ocean bottom pressure recorders together with earthquake parameters are used to select precomputed scenarios from a tsunami propagation model and to forecast arrival times and inundation at specific points along the West coast of Vancouver Island. WARN's architecture is extremely flexible and can incorporate high rate GNSS based observations.

    An earthquake monitoring and early warning system for a large-scale city gas network has been developed in the Tokyo Metropolitan area. The monitoring system consists of 356 earthquake sensors. Once an earthquake occurs, values monitored by these sensors will be sent to the supply control center by radio. Then estimation of damage to customers` buildings and pipelines, estimation of the magnitude and hypocenter, evaluation of the response spectrum, and decision analysis whether to shut-off or maintain the supply will be conducted. The system will play an important role in mitigating gas-related secondary disasters due to earthquakes.

    Seismic monitoring in Algeria has seen great changes since the Boumerdes earthquake of 21 May 2003. Indeed, the installation of a new digital seismic network has resulted in a significant upgrade of the previous analog telemetry network. During the last four years, the number of stations in operation has increased substantially from 25 to 69, and 20 of these are broadband, 2 are very broadband, 47 are short period. 21 are equipped with accelerometers. They are all managed by Antelope software from Kinemetrics (US Cie), and they are all connected in real time and use various modes of transmission (e.g., satellite, internet, mobile phone). The spatial repartition of the stations now cover most of northern Algeria. In addition, 70 GPS stations have recently been added to this seismological network, most of them collocated with the seismological stations. Since the installation of the network, the records of local or distant events have improved significantly. The automatic processing of the data in a few minutes allows alert messages to be distributed to Civil Defense and other national authorities to react promptly to any emergency. The current strategy is to improve the data quality, to increase the density of the network by adding about 50 new stations, to reduce the processing time, and to reduce the time needed to send out an alert message. The result should be greatly improved network performance, which will lead to an effective early-warning system.

    Wireless sensor networks (WSNs) are one of the emerging areas that received great attention during the last few years. This is mainly due to the fact that WSNs have provided scientists with the capability of developing real-time monitoring systems equipped with sensors based on Micro-Electro-Mechanical Systems (MEMS). WSNs have great potential for many applications in environmental monitoring since the sensor nodes that comprised from can host several MEMS sensors (such as temperature, humidity, inertial, pressure, strain-gauge) and transducers (such as position, velocity, acceleration, vibration). The resulting devices are small and inexpensive but with limited memory and computing resources. Each sensor node contains a sensing module which along with an RF transceiver. The communication is broadcast-based since the network topology can change rapidly due to node failures [1]. Sensor nodes can transmit their measurements to central servers through gateway nodes without any processing or they make preliminary calculations locally in order to produce results that will be sent to central servers [2]. Based on the above characteristics, two prototypes using WSNs are presented in this paper: A Landslide detection system and a Flood warning system. Both systems sent their data to central processing server where the core of processing routines exists. Transmission is made using Zigbee and IEEE 802.11b protocol but is capable to use VSAT communication also. Landslide detection system uses structured network topology. Each measuring node comprises of a columnar module that is half buried to the area under investigation. Each sensing module contains a geophone, an inclinometer and a set of strain gauges. Data transmitted to central processing server where possible landslide evolution is monitored. Flood detection system uses unstructured network topology since the failure rate of sensor nodes is expected higher. Each sensing module contains a custom water level sensor

  5. Identifying early-warning signals of critical transitions with strong noise by dynamical network markers

    2015-01-01

    Identifying early-warning signals of a critical transition for a complex system is difficult, especially when the target system is constantly perturbed by big noise, which makes the traditional methods fail due to the strong fluctuations of the observed data. In this work, we show that the critical transition is not traditional state-transition but probability distribution-transition when the noise is not sufficiently small, which, however, is a ubiquitous case in real systems. We present a model-free computational method to detect the warning signals before such transitions. The key idea behind is a strategy: “making big noise smaller” by a distribution-embedding scheme, which transforms the data from the observed state-variables with big noise to their distribution-variables with small noise, and thus makes the traditional criteria effective because of the significantly reduced fluctuations. Specifically, increasing the dimension of the observed data by moment expansion that changes the system from state-dynamics to probability distribution-dynamics, we derive new data in a higher-dimensional space but with much smaller noise. Then, we develop a criterion based on the dynamical network marker (DNM) to signal the impending critical transition using the transformed higher-dimensional data. We also demonstrate the effectiveness of our method in biological, ecological and financial systems. PMID:26647650

The key idea behind is a strategy: “making big noise smaller” by a distribution-embedding scheme, which transforms the data from the observed state-variables with big noise to their distribution-variables with small noise, and thus makes the traditional criteria effective because of the significantly reduced fluctuations. Specifically, increasing the dimension of the observed data by moment expansion that changes the system from state-dynamics to probability distribution-dynamics, we derive new data in a higher-dimensional space but with much smaller noise. Then, we develop a criterion based on the dynamical network marker (DNM) to signal the impending critical transition using the transformed higher-dimensional data. We also demonstrate the effectiveness of our method in biological, ecological and financial systems.

  7. The Earthquake Network Project: Toward a Crowdsourced Smartphone-Based Earthquake Early Warning System

    The Earthquake Network research project implements a crowdsourced earthquake early warning system based on smartphones. Smartphones, which are made available by the global population, exploit the Internet connection to report a signal to a central server every time a vibration is detected by the on-board accelerometer sensor. This paper introduces a statistical approach for the detection of earthquakes from the data coming from the network of smartphones. The approach allows to handle a dynamic network in which the number of active nodes constantly changes and where nodes are heterogeneous in terms of sensor sensibility and transmission delay. Additionally, the approach allows to keep the probability of false alarm under control. The statistical approach is applied to the data collected by three subnetworks related to the cities of Santiago de Chile, Iquique (Chile) and Kathmandu (Nepal). The detection capabilities of the approach are discussed in terms of earthquake magnitude and detection delay. A simulation study is carried out in order to link the probability of detection and the detection delay to the behaviour of the network under an earthquake event.

    A multi-institutional partnership, the US Agency for International Development’s Famine Early Warning System Network (FEWS NET) provides routine monitoring of climatic, agricultural, market, and socioeconomic conditions in over 20 countries. FEWS NET supports and informs disaster relief decisions that impact millions of people and involve billions of dollars. In this chapter, we focus on some of FEWS NET’s hydrologic monitoring tools, with a specific emphasis on combining “low frequency” and “high frequency” assessment tools. Low frequency assessment tools, tied to water and food balance estimates, enable us to evaluate and map long-term tendencies in food security. High frequency assessments are supported by agrohydrologic models driven by satellite rainfall estimates, such as the Water Requirement Satisfaction Index (WRSI). Focusing on eastern Africa, we suggest that both these high and low frequency approaches are necessary to capture the interaction of slow variations in vulnerability and the relatively rapid onset of climatic shocks.

    The aim of this study was to analyse the occurrence of alcohol dependence and abuse in relation to variables reflecting social network and leisure time, social class, education, occupation and family conditions. The study was based on the second wave of interviews performed within the longitudinal study of Women and Alcohol in Göteborg. In this present study we analysed 416 face-to-face interviews performed in 1995 96. Women with only one or no friends for support had higher rates of alcohol dependence and abuse than did women with more friends. Women with high rates of alcohol dependence or abuse did not take part in cultural events as much as women with low rates of alcohol dependence and abuse. Women with homemaking skills and gardening as leisure time interests had lower prevalences of alcohol dependence and abuse. In general, women with diagnoses of alcohol dependence and abuse in this population-based sample were not alone and without a social network. However, their pattern of activity differed slightly from those without such diagnoses. The association between women with alcohol dependence and abuse and leisure time activities is probably circular: a poor social network and low participation in social activities increase the risk of alcohol dependence and abuse, and alcohol dependence and abuse lead to low participation in social activities.

    The US Agency for International Development (USAID) s Famine Early Warning System Network (FEWS NET) provides monitoring and early warning support to decision makers responsible for responding to food insecurity emergencies on three continents. FEWS NET uses satellite remote sensing and ground observations of rainfall and vegetation in order to provide information on drought, floods and other extreme weather events to decision makers. Previous research has presented results from a professional review questionnaire with FEWS NET expert end-users whose focus was to elicit Earth observation requirements. The review provided FEWS NET operational requirements and assessed the usefulness of additional remote sensing data. Here we analyzed 1342 food security update reports from FEWS NET. The reports consider the biophysical, socioeconomic, and contextual influences on the food security in 17 countries in Africa from 2000-2009. The objective was to evaluate the use of remote sensing information in comparison with other important factors in the evaluation of food security crises. The results show that all 17 countries use rainfall information, agricultural production statistics, food prices and food access parameters in their analysis of food security problems. The reports display large scale patterns that are strongly related to history of the FEWS NET program in each country. We found that rainfall data was used 84% of the time, remote sensing of vegetation 28% of the time, and gridded crop models 10%, reflecting the length of use of each product in the regions. More investment is needed in training personnel on remote sensing products to improve use of data products throughout the FEWS NET system.

  11. Road Accident Prevention with Instant Emergency Warning Message Dissemination in Vehicular Ad-Hoc Network.

    2015-01-01

    A Road Accident Prevention (RAP) scheme based on Vehicular Backbone Network (VBN) structure is proposed in this paper for Vehicular Ad-hoc Network (VANET). The RAP scheme attempts to prevent vehicles from highway road traffic accidents and thereby reduces death and injury rates. Once the possibility of an emergency situation (i.e. an accident) is predicted in advance, instantly RAP initiates a highway road traffic accident prevention scheme. The RAP scheme constitutes the following activities: (i) the Road Side Unit (RSU) constructs a Prediction Report (PR) based on the status of the vehicles and traffic in the highway roads, (ii) the RSU generates an Emergency Warning Message (EWM) based on an abnormal PR, (iii) the RSU forms a VBN structure and (iv) the RSU disseminates the EWM to the vehicles that holds the high Risk Factor (RF) and travels in High Risk Zone (HRZ). These vehicles might reside either within the RSU's coverage area or outside RSU's coverage area (reached using VBN structure). The RAP scheme improves the performance of EWM dissemination in terms of increase in notification and decrease in end-to-end delay. The RAP scheme also reduces infrastructure cost (number of RSUs) by formulating and deploying the VBN structure. The RAP scheme with VBN structure improves notification by 19 percent and end-to-end delay by 14.38 percent for a vehicle density of 160 vehicles. It is also proved from the simulation experiment that the performance of RAP scheme is promising in 4-lane highway roads.

    The SCSN is the modern digital ground motion seismic network in Southern California and performs the following tasks: 1) Operates remote seismic stations and the central data processing systems in Pasadena; 2) Generates and reports real-time products including location, magnitude, ShakeMap, aftershock probabilities and others; 3) Responds to FEMA, CalOES, media, and public inquiries about earthquakes; 4) Manages the production, archival, and distribution of waveforms, phase picks, and other data at the SCEDC; 5) Contributes to development and implementation of the demonstration EEW system called CISN ShakeAlert. Initially, the ShakeAlert project was funded through the US Geological Survey (USGS) and in early 2012, the Gordon and Betty Moore Foundation provided three years of new funding for EEW research and development for the US west coast. Recently, we have also received some Urban Areas Security Initiative (UASI) funding to enhance the EEW capabilities for the local UASI region by making our system overall faster, more reliable and redundant than the existing system. The additional and upgraded stations will be capable of decreasing latency and ensuring data delivery by using more reliable and redundant telemetry pathways. Overall, this will enhance the reliability of the earthquake early warnings by providing denser station coverage and more resilient data centers than before. * Seismic Datalogger upgrade: replaces existing dataloggers with modern equipment capable of sending one-second uncompressed packets and utilizing redundant Ethernet telemetry. * GPS upgrade: replaces the existing GPS receivers and antennas, especially at "zipper array" sites near the major faults, with receivers that perform on-board precise point positioning to calculate position and velocity in real time and stream continuous data for use in EEW calculations. * New co-located seismic/GPS stations: increases station density and reduces early warning delays that are incurred by travel

    2010-05-01

    The purpose of the current study is to review the current technical and scientific state of wireless sensor networks (WSNs) with application on natural hazards. WSN have received great attention from the research community in the last few years, mainly due to the theoretical and practical efforts from challenges that led to mature solutions and adoption of standards, such as Bluetooth [2] and ZigBee [3]. Wireless technology solutions allows Micro-ElectroMechanical Systems sensors (MEMS) to be integrated (with all the necessary circuitry) to small wireless capable devices, the nodes. Available MEMS today include pressure, temperature, humidity, inertial and strain-gauge sensors as well as transducers for velocity, acceleration, vibration, flow position and inclination [4]. A WSN is composed by a large number of nodes which are deployed densely adjacent to the area under monitoring. Each node collects data which transmitted to a gateway. The main requirements that WSNs must fulfilled are quite different than those of ad-hoc networks. WSNs have to be self-organized (since the positions of individual nodes are not known in advance), they must present cooperative processing of tasks (where groups of nodes cooperate in order to provide the gathered data to the user), they require security mechanisms that are adaptive to monitoring conditions and all algorithms must be energy optimized. In this paper, the state of the art in hardware, software, algorithms and protocols for WSNs, focused on natural hazards, is surveyed. Architectures for WSNs are investigated along with their advantages and drawbacks. Available research prototypes as well as commercially proposed solutions that can be used for natural hazards monitoring and early warning systems are listed and classified. [1] I.F. Akyildiz, W.

    2016-08-01

    As a consequence of the Chernobyl nuclear power plant accident in 1986, all European countries have installed automatic dosimetry network stations as well as air sampling systems for the monitoring of airborne radioactivity. In Europe, at present, almost 5,000 stations measure dose rate values in nearly real time. In addition, a few hundred air samplers are operated. Most of them need extended accumulation times with no real-time capability. National dose rate data are provided to the European Commission (EC) via the EUropean Radiological Data Exchange Platform (EURDEP). In case of a nuclear emergency with transboundary implications, the EC may issue momentous recommendations to EU member states based on the radiological data collected by EURDEP. These recommendations may affect millions of people and could have severe economic and sociological consequences. Therefore, the reliability of the EURDEP data is of key importance. Unfortunately, the dose rate and activity concentration data are not harmonized between the different networks. Therefore, within the framework of the European Metrology Research Programme (EMRP), 16 European institutions formed the consortium MetroERM with the aim to improve the metrological foundation of measurements and to introduce a pan-European harmonization for the collation and evaluation of radiological data in early warning network systems. In addition, a new generation of detector systems based on spectrometers capable of providing both reliable dose rate values as well as nuclide specific information in real time are in development. The MetroERM project and its first results will be presented and discussed in this article. PMID:27356052

    To detect radiological incidents, all members of the European Union have installed nationwide radiological early warning networks. Most of the installed detector systems supply only dosimetric information. Novel spectrometry systems are considered to be good candidates for a new detector generation for environmental radiation monitoring because they will supply both nuclide-specific information and ambient dose equivalent rate values. Four different detector types were chosen and compared with each other (LaBr3, CeBr3, SrI2 scintillation detectors, and CdZnTe, a semiconductor detector). As a first step, the inherent background of these detectors was measured in the low background underground laboratory UDO II of PTB. As a second step, the relative detection sensitivity between the various detectors was determined at different energies. Finally, the detectors were exposed to a 4π-radiation field of radon progeny in PTB's radon chamber. The obtained results show that the investigated detectors are well suited for environmental radiation monitoring.

  19. Development of a flood-warning network and flood-inundation mapping for the Blanchard River in Ottawa, Ohio

    2011-01-01

    Digital flood-inundation maps of the Blanchard River in Ottawa, Ohio, were created by the U.S. Geological Survey (USGS) in cooperation with the U.S. Department of Agriculture, Natural Resources Conservation Service and the Village of Ottawa, Ohio. The maps, which correspond to water levels (stages) at the USGS streamgage at Ottawa (USGS streamgage site number 04189260), were provided to the National Weather Service (NWS) for incorporation into a Web-based flood-warning Network that can be used in conjunction with NWS flood-forecast data to show areas of predicted flood inundation associated with forecasted flood-peak stages. Flood profiles were computed by means of a step-backwater model calibrated to recent field measurements of streamflow. The step-backwater model was then used to determine water-surface-elevation profiles for 12 flood stages with corresponding streamflows ranging from less than the 2-year and up to nearly the 500-year recurrence-interval flood. The computed flood profiles were used in combination with digital elevation data to delineate flood-inundation areas. Maps of the Village of Ottawa showing flood-inundation areas overlain on digital orthophotographs are presented for the selected floods. As part of this flood-warning network, the USGS upgraded one streamgage and added two new streamgages, one on the Blanchard River and one on Riley Creek, which is tributary to the Blanchard River. The streamgage sites were equipped with both satellite and telephone telemetry. The telephone telemetry provides dual functionality, allowing village officials and the public to monitor current stage conditions and enabling the streamgage to call village officials with automated warnings regarding flood stage and/or predetermined rates of stage increase. Data from the streamgages serve as a flood warning that emergency management personnel can use in conjunction with the flood-inundation maps by to determine a course of action when flooding is imminent.

    This article presents a novel methodology to assess flood risk to people by integrating people's vulnerability and ability to cushion hazards through coping and adapting. The proposed approach extends traditional risk assessments beyond material damages; complements quantitative and semi-quantitative data with subjective and local knowledge, improving the use of commonly available information; produces estimates of model uncertainty by providing probability distributions for all of its outputs. Flood risk to people is modeled using a spatially explicit Bayesian network model calibrated on expert opinion. Risk is assessed in terms of: (1) likelihood of non-fatal physical injury; (2) likelihood of post-traumatic stress disorder; (3) likelihood of death. The study area covers the lower part of the Sihl valley (Switzerland) including the city of Zurich. The model is used to estimate the benefits of improving an existing Early Warning System, taking into account the reliability, lead-time and scope (i.e. coverage of people reached by the warning). Model results indicate that the potential benefits of an improved early warning in terms of avoided human impacts are particularly relevant in case of a major flood event: about 75 % of fatalities, 25 % of injuries and 18 % of post-traumatic stress disorders could be avoided.

    Illicit drug users sustain the epidemics of human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS), hepatitis C (HCV), and sexually transmitted infections (STIs). Substance abuse treatment programs present a major intervention point in stemming these epidemics. As a part of the "Infections and Substance Abuse" study, established by the National Drug Abuse Treatment Clinical Trials Network, sponsored by National Institute on Drug Abuse, three surveys were developed; for treatment program administrators, for clinicians, and for state and District of Columbia health and substance abuse department administrators, capturing service availability, government mandates, funding, and other key elements related to the three infection groups. Treatment programs varied in corporate structure, source of revenue, patient census, and medical and non-medical staffing; medical services, counseling services, and staff education targeted HIV/AIDS more often than HCV or STIs. The results from this study have the potential to generate hypotheses for further health services research to inform public policy. PMID:16716846

    Cocaine and alcohol are two substances of abuse that prominently affect the central nervous system (CNS). Repeated exposure to cocaine and alcohol leads to longstanding changes in gene expression, and subsequent functional CNS plasticity, throughout multiple brain regions. Epigenetic modifications of histones are one proposed mechanism guiding these enduring changes to the transcriptome. Characterizing the large number of available biological relationships as network models can reveal unexpected biochemical relationships. Clustering analysis of variation from whole-genome sequencing of gene expression (RNA-Seq) and histone H3 lysine 4 trimethylation (H3K4me3) events (ChIP-Seq) revealed the underlying structure of the transcriptional and epigenomic landscape within hippocampal postmortem brain tissue of drug abusers and control cases. Distinct sets of interrelated networks for cocaine and alcohol abuse were determined for each abusive substance. The network approach identified subsets of functionally related genes that are regulated in agreement with H3K4me3 changes, suggesting cause and effect relationships between this epigenetic mark and gene expression. Gene expression networks consisted of recognized substrates for addiction, such as the dopamine- and cAMP-regulated neuronal phosphoprotein PPP1R1B/DARPP-32 and the vesicular glutamate transporter SLC17A7/VGLUT1 as well as potentially novel molecular targets for substance abuse. Through a systems biology based approach our results illustrate the utility of integrating epigenetic and transcript expression to establish relevant biological networks in the human brain for addiction. Future work with laboratory models may clarify the functional relevance of these gene networks for cocaine and alcohol, and provide a framework for the development of medications for the treatment of addiction.

    Changes in personal network composition, support and structure over 12 months were examined in 377 women from residential (n=119) and intensive outpatient substance abuse treatment (n=258) through face-to-face interviews utilizing computer based data collection. Personal networks of women who entered residential treatment had more substance users, more people with whom they had used alcohol and/or drugs, and fewer people from treatment programs or self- help groups than personal networks of women who entered intensive outpatient treatment. By 12 months post treatment intake, network composition improved for women in residential treatment; however, concrete support was still lower and substance users are still more prevalent in their networks. Network composition of women in outpatient treatment remained largely the same over time. Both groups increased cohesiveness within the network over 12 months. Targeting interventions that support positive changes in personal networks may heighten positive long term outcomes for women entering treatment.

    The GAGE facility, managed by UNAVCO, maintains and operates about 1300 GNSS stations distributed across North and Central America as part of the EarthScope Plate Boundary Observatory (PBO) and the Continuously Operating Caribbean GPS Observational Network (COCONet). UNAVCO has upgraded about 450 stations in these networks to real-time and high-rate (RT-GNSS) and included surface meteorological instruments. The majority of these streaming stations are part of the PBO but also include approximately 50 RT-GNSS stations in the Caribbean and Central American region as part of the COCONet and TLALOCNet projects. Based on community input UNAVCO has been exploring ways to increase the capability and utility of these resources to improve our understanding in diverse areas of geophysics including seismic, volcanic, magmatic and tsunami deformation sources, extreme weather events such as hurricanes and storms, and space weather. The RT-GNSS networks also have the potential to profoundly transform our ability to rapidly characterize geophysical events, provide early warning, as well as improve hazard mitigation and response. Specific applications currently under development with university, commercial, non-profit and government collaboration on national and international scales include earthquake and tsunami early warning systems and near real-time tropospheric modeling of hurricanes and precipitable water vapor estimate assimilation. Using tsunami early warning as an example, an RT-GNSS network can provide multiple inputs in an operational system starting with rapid assessment of earthquake sources and associated deformation which informs the initial modeled tsunami. The networks can then can also provide direct measurements of the tsunami wave heights and propagation by tracking the associated ionospheric disturbance from several 100's of km away as the waves approaches the shoreline. These GNSS based constraints can refine the tsunami and inundation models and potentially

    Biomarkers have gained immense scientific interest and clinical value in the practice of medicine. With unprecedented advances in high-throughput technologies, research interest in identifying novel and customized disease biomarkers for early detection, diagnosis, or drug responses is rapidly growing. Biomarkers can be identified in different levels of molecular biomarkers, networks biomarkers and dynamical network biomarkers (DNBs). The latter is a recently developed concept which relies on the idea that a cell is a complex system whose behavior is emerged from interplay of various molecules, and this network of molecules dynamically changes over time. A DNB can serve as an early-warning signal of disease progression, or as a leading network that drives the system into the disease state, and thus unravels mechanisms of disease initiation and progression. It is therefore of great importance to identify DNBs efficiently and reliably. In this work, the problem of DNB identification is defined as a multi-objective optimization problem, and a framework to identify DNBs out of time-course high-throughput data is proposed. Temporal gene expression data of a lung injury with carbonyl chloride inhalation exposure has been used as a case study, and the functional role of the discovered biomarker in the pathogenesis of lung injury has been thoroughly analyzed.

    The effect of 12-step mutual help groups (e.g., Narcotics Anonymous) on members' friendship networks has received little attention. This 1-year longitudinal study examined such effects in a sample of 2,337 male substance abuse inpatients, 57.7% of whom became significantly involved in 12-step activities (e.g., reading program literature, attending meetings) after treatment. An a priori model of the interplay of 12-step involvement) and friendship networks was tested using structural equation modeling, and found to have excellent fit to the data. Twelve-step group involvement after treatment predicted better general friendship characteristics (e.g., number of close friends) and substance abuse-specific friendship characteristics (e.g., proportion of friends who abstain from drugs and alcohol) at follow-up. Results are discussed in terms of how mutual help group involvement benefits patients and how the self-help group evaluation paradigm should be broadened. PMID:9231993

    This study compared compositional, social support, and structural characteristics of personal networks among women in residential (RT) and intensive outpatient (IOP) substance abuse treatment. The study sample included 377 women from inner-city substance use disorder treatment facilities. Respondents were asked about 25 personal network members known within the past 6 months, characteristics of each (relationship, substance use, types of support), and relationships between each network member. Differences between RT women and IOP women in personal network characteristics were identified using Chi-square and t-tests. Compared to IOP women, RT women had more substance users in their networks, more network members with whom they had used substances and fewer network members who provided social support. These findings suggest that women in residential treatment have specific network characteristics, not experienced by women in IOP, which may make them more vulnerable to relapse; they may therefore require interventions that target these specific network characteristics in order to reduce their vulnerability to relapse.

    The Istanbul EEW network consisting of 10 inland and 5 OBS strong motion stations located close to the Main Marmara Fault zone is operated by KOERI. Data transmission between the remote stations and the base station at KOERI is provided both with satellite and fiber optic cable systems. The continuous on-line data from these stations is used to provide real time warning for emerging potentially disastrous earthquakes. The data transmission time from the remote stations to the KOERI data center is a few milliseconds through fiber optic lines and less than a second via satellites. The early warning signal (consisting three alarm levels) is communicated to the appropriate servo shut-down systems of the receipent facilities, that automatically decide proper action based on the alarm level. Istanbul Gas Distribution Corporation (IGDAS) is one of the end users of the EEW signal. IGDAS, the primary natural gas provider in Istanbul, operates an extensive system 9,867 km of gas lines with 550 district regulators and 474,000 service boxes. State of-the-art protection systems automatically cut natural gas flow when breaks in the pipelines are detected. Since 2005, buildings in Istanbul using natural gas are required to install seismometers that automatically cut natural gas flow when certain thresholds are exceeded. IGDAS uses a sophisticated SCADA (supervisory control and data acquisition) system to monitor the state-of-health of its pipeline network. This system provides real-time information about quantities related to pipeline monitoring, including input-output pressure, drawing information, positions of station and RTU (remote terminal unit) gates, slum shut mechanism status at 581 district regulator sites. The SCADA system of IGDAŞ receives the EEW signal from KOERI and decide the proper actions according to the previously specified ground acceleration levels. Presently, KOERI sends EEW signal to the SCADA system of IGDAS Natural Gas Network of Istanbul. The EEW signal

    The prevention of accidents is one of the most important goals of ad hoc networks in smart cities. When an accident happens, dynamic sensors (e.g., citizens with smart phones or tablets, smart vehicles and buses, etc.) could shoot a video clip of the accident and send it through the ad hoc network. With a video message, the level of seriousness of the accident could be much better evaluated by the authorities (e.g., health care units, police and ambulance drivers) rather than with just a simple text message. Besides, other citizens would be rapidly aware of the incident. In this way, smart dynamic sensors could participate in reporting a situation in the city using the ad hoc network so it would be possible to have a quick reaction warning citizens and emergency units. The deployment of an efficient routing protocol to manage video-warning messages in mobile Ad hoc Networks (MANETs) has important benefits by allowing a fast warning of the incident, which potentially can save lives. To contribute with this goal, we propose a multipath routing protocol to provide video-warning messages in MANETs using a novel game-theoretical approach. As a base for our work, we start from our previous work, where a 2-players game-theoretical routing protocol was proposed to provide video-streaming services over MANETs. In this article, we further generalize the analysis made for a general number of N players in the MANET. Simulations have been carried out to show the benefits of our proposal, taking into account the mobility of the nodes and the presence of interfering traffic.Finally, we also have tested our approach in a vehicular ad hoc network as an incipient start point to develop a novel proposal specifically designed for VANETs.

    Drug abuse treatment programs and university-based research centers collaborate to test emerging therapies for alcohol and drug disorders in the National Drug Abuse Treatment Clinical Trials Network (CTN). Programs participating in the CTN completed Organizational Surveys (n=106 of 112; 95% response rate) and Treatment Unit Surveys (n=348 of 384; 91% response rate) to describe the levels of care, ancillary services, patient demographics, patient drug use and co-occurring conditions. Analyses describe the corporations participating in the CTN and provide an exploratory assessment of variation in treatment philosophies. A diversity of treatment centers participate in the CTN; not for profit organizations with a primary mission of treating alcohol and drug disorders dominate. Compared to National Survey of Substance Abuse Treatment Services (N-SSATS), programs located in medical settings are over-represented and centers that are mental health clinics are under-represented. Outpatient, methadone, long-term residential and inpatient treatment units differed on patients served and services provided. Larger programs with higher counselor caseloads in residential settings reported more social model characteristics. Programs with higher social model scores were more likely to offer self-help meetings, vocational services and specialized services for women. Conversely, programs with accreditation had less social model influence. The CTN is an ambitious effort to engage community-based treatment organizations into research and more fully integrate research and practice.

    The use of dumpers is one of the main causes of accidents in construction sites, many of them with fatal consequences. These kinds of work machines have many blind angles that complicate the driving task due to their large size and volume. To guarantee safety conditions is necessary to use automatic aid systems that can detect and locate the different objects and people in a work area. One promising solution is a radar network based on low-cost radar transceivers aboard the dumper. The complete system is specified to operate with a very low false alarm rate to avoid unnecessary stops of the dumper that reduce its productivity. The main sources of false alarm are the heavy ground clutter, and the interferences between the radars of the network. This article analyses the clutter for LFM signaling and proposes the use of Offset Linear Frequency Modulated Continuous Wave (OLFM-CW) as radar signal. This kind of waveform can be optimized to reject clutter and self-interferences. Jointly, a data fusion chain could be used to reduce the false alarm rate of the complete radar network. A real experiment is shown to demonstrate the feasibility of the proposed system.

    The risk associated with natural and social phenomena has notably increased in modern societies. On the other hand, socio-natural hazards have increased and diversified, in association with economic development. During 2010 and 2011, Colombia faced one of the most severe wet seasons in decades. One of the most significant impacts of this flood emergency was the demonstration of poor preparedness of communities, local authorities, and regional and national authorities to confront situations of large coverage. The emergencies occurred during 2010 and 2011, induced in association with a strong La Niña event, immediately demanded environmental and risk management authorities to provide communities with basic tools to understand the dynamics associated with excesses of rainfall and mitigate the possible impacts in their populations. For this reason, the Regional Autonomous Corporation of Central Antioquia, Colombia (CORANTIOQUIA) funded a project aimed to the design and conformation of a social network for early warnings of events associated to floods, torrential floods, and mass movements in 80 municipalities of the department of Antioquia, Colombia. For the execution of this project, the Corporation invited the Faculty of Engineering of the University of Antioquia. This talk aims to socialize this inititative that looked for integrating scientific and technical knowledge with popular knowledge in order to provide Latin American communities with tools to mitigate the possible impacts of global change.

    Low- and middle-income countries (LMIC) lack the research infrastructure and capacity to conduct rigorous substance abuse and mental health effectiveness clinical trials to guide clinical practice. A partnership between the Florida Node Alliance of the United States National Drug Abuse Treatment Clinical Trials Network and the National Institute of Psychiatry in Mexico was established in 2011 to improve substance abuse practice in Mexico. The purpose of this partnership was to develop a Mexican national clinical trials network of substance abuse researchers and providers capable of implementing effectiveness randomized clinical trials in community-based settings. A technology transfer model was implemented and ran from 2011-2013. The Florida Node Alliance shared the "know how" for the development of the research infrastructure to implement randomized clinical trials in community programs through core and specific training modules, role-specific coaching, pairings, modeling, monitoring, and feedback. The technology transfer process was bi-directional in nature in that it was informed by feedback on feasibility and cultural appropriateness for the context in which practices were implemented. The Institute, in turn, led the effort to create the national network of researchers and practitioners in Mexico and the implementation of the first trial. A collaborative model of technology transfer was useful in creating a Mexican researcher-provider network that is capable of changing national practice in substance abuse research and treatment. Key considerations for transnational technology transfer are presented.

    The purpose of this study is to establish a turbidity forecasting model as well as an early-warning system for turbidity management using rainfall records as the input variables. The Taipei Water Source Domain was employed as the study area, and ANOVA analysis showed that the accumulative rainfall records of 1-day Ping-lin, 2-day Ping-lin, 2-day Fei-tsui, 2-day Shi-san-gu, 2-day Tai-pin and 2-day Tong-hou were the six most significant parameters for downstream turbidity development. The artificial neural network model was developed and proven capable of predicting the turbidity concentration in the investigated catchment downstream area. The observed and model-calculated turbidity data were applied to developing the turbidity early-warning system. Using a previously determined turbidity as the threshold, the rainfall criterion, above which the downstream turbidity would possibly exceed this respective threshold turbidity, for the investigated rain gauge stations was determined. An exemplary illustration demonstrated the effectiveness of the proposed turbidity early-warning system as a precautionary alarm of possible significant increase of downstream turbidity. This study is the first report of the establishment of the turbidity early-warning system. Hopefully, this system can be applied to source water turbidity forecasting during storm events and provide a useful reference for subsequent adjustment of drinking water treatment operation.

    The past two decades have witnessed a huge progress in the development, implementation and testing of Earthquakes Early Warning Systems (EEWS) worldwide, as the result of a joint effort of the seismological and earthquake engineering communities to set up robust and efficient methodologies for the real-time seismic risk mitigation. The leading experience of the operational early warning system implemented by the Japan Meteorological Agency showed the effectiveness of a combined onsite and network-based approach to rapidly broadcast the rapid warning after a potential damaging earthquake. At the nation-wide scale, the Japanese system makes use of real-time data streamed by the extremely dense accelerograph array (about 1000 seismic instruments) deployed across Japan. With more than 750 accelerometric stations installed over all the active seismic zones, target cities and strategic infrastructures, Italy has the potential for a nation-wide early warning system, although the communication network and data sharing must be expanded and improved. A significant number of these stations are nodes of the RAN (Italian Accelerometric Network) managed by the Italian national emergency management department (Dipartimento della Protezione Civile, DPC), whose data are used for emergency response services. In the framework of the REAKT-Strategies and tools for Real Time Earthquake RisK ReducTion FP7 European project, the AMRA-RISSCLab group is engaged in a feasibility study on the implementation of the EEW software PRESTo earthquake early warning platforms on the Italian accelerometric network (RAN) PRESTo (PRobabilistic and Evolutionary early warning SysTem) is a highly configurable and easily portable platform for Earthquake Early Warning. The system processes the live accelerometric streams from the stations of a seismic network to promptly provide probabilistic and evolutionary estimates of location and magnitude of detected earthquakes while they are occurring, as well as

    Objective Individuals with direct care responsibilities in 348 drug abuse treatment units were surveyed to obtain a description of the workforce and to assess support for evidence-based therapies. Methods Surveys were distributed to 112 programs participating in the National Drug Abuse Treatment Clinical Trials Network (CTN). Descriptive analyses characterized the workforce. Analyses of covariance tested the effects of job category (counselors, medical staff, manager-supervisors, and support staff) on opinions about evidence-based practices and controlled for the effects of education, modality (outpatient or residential), race, and gender. Results Women made up two-thirds of the CTN workforce. One-third of the workforce had a master’s or doctoral degree. Responses from 1,757 counselors, 908 support staff, 522 managers-supervisors, and 511 medical staff (71% of eligible participants) suggested that the variables that most consistently influenced responses were job category (19 of 22 items) and education (20 of 22 items). Managers-supervisors were the most supportive of evidence-based therapies, and support staff were the least supportive. Generally, individuals with graduate degrees had more positive opinions about evidence-based therapies. Support for using medications and contingency management was modest across job categories. Conclusions The relatively traditional beliefs of support staff could inhibit the introduction of evidence-based practices. Programs initiating changes in therapeutic approaches may benefit from including all employees in change efforts. PMID:17287373

    The purpose of this article is to review both main findings and secondary analyses from studies of abstinence incentives conducted in the National Drug Abuse Treatment Clinical Trials Network (CTN). Previous research has supported the efficacy of tangible incentives provided contingent on evidence of recent drug abstinence. CTN conducted the first multisite effectiveness trial of this novel intervention. Study participants were stimulant abusers (N = 803) participating in treatment at 14 clinical sites and randomly assigned to treatment as usual with or without a prize draw incentive program. Study participants could earn up to $400 over 3 months for submission of drug-free urine and breath (BAL) specimens. Three-month retention was significantly improved by incentives offered to psychosocial counseling clients (50% incentive vs. 35% control retained), whereas ongoing stimulant drug use was significantly reduced in methadone maintenance clients (54.4% incentive vs. 38.7% control samples testing stimulant-negative). In both settings, duration of continuous abstinence achieved was improved in the incentive condition. These studies support effectiveness of one abstinence incentive intervention and highlight the different outcomes that can be expected with application in methadone maintenance versus psychosocial counseling treatment settings. Secondary analyses have shown the importance of early treatment positive versus negative urine screens in moderating the outcome of abstinence incentives and have explored both safety and cost-effectiveness of the intervention. Implications for the use of motivational incentive methods in clinical practice are discussed.

  11. Quantifying the tsunami-warning capability of a global sea-level network based on past, present, and possible future sensor distributions

    A tsunami warning center (TWC) operates on the fundamental principle that seismic waves travel 20 to 30 times faster through the earth than tsunamis travel through the oceans. This speed difference allows TWC scientists to determine the tsunami-generating potential of an earthquake, or even analyze the tsunami itself, before the tsunami reaches threatened coastlines. Given that we know where tsunami-generating earthquakes are likely to occur, how fast both seismic and tsunami waves propagate, and the distribution of both seismic and sea-level sensors installed around the world, we can predict how rapidly a TWC should be able to respond to any tsunami-generating earthquake and thus which coastlines will receive a tsunami warning in time to react and which coastlines will get little or no warning (Becker et al., EOS Trans. AGU, 2010). TWCs can forecast a tsunami and issue a warning based on earthquake characteristics alone, but near real-time sea-level measurements are necessary for the TWC to refine its forecast and expand, narrow, or cancel tsunami warnings, to not only protect more lives and property when a tsunami is more severe than initially forecast, but to also prevent unnecessary and costly evacuations when a tsunami is less intense and/or more focused than initially forecast. To determine how soon a TWC will have useful sea-level data after an earthquake, we calculated tsunami travel times (TTTs) from likely tsunami sources, i.e., thrust faults at subduction zones, to both coastal and deep-ocean sea level sensors monitored by the Pacific Tsunami Warning Center (PTWC). For this purpose we geographically sampled the axes of deep-sea trenches with a geodesic grid to ensure equal spacing of simulated sources. We then calculated global TTT grids for each of these sources and sampled each grid at the locations of coastal and deep-ocean sea-level gauges currently monitored by the Pacific Tsunami Warning Center (PTWC). We then added each gauge's transmission

    There is a growing body of research supporting the use of buprenorphine and other medication assisted treatments (MATs) for the rapidly accelerating opioid epidemic in the United States. Despite numerous advantages of buprenorphine (accessible in primary care, no daily dosing required, minimal stigma), implementation has been slow. As the field progresses, there is a need to understand the impact of participation in practitioner-scientist research networks on acceptance and uptake of buprenorphine. This paper examines the impact of research network participation on counselor attitudes toward buprenorphine addressing both counselor-level characteristics and program-level variables using hierarchical linear modeling (HLM) to account for nesting of counselors within treatment programs. Using data from the National Treatment Center Study, this project compares privately funded treatment programs (n=345) versus programs affiliated with the National Institute on Drug Abuse Clinical Trials Network (CTN) (n=198). Models included 922 counselors in 172 CTN programs and 1,203 counselors in 251 private programs. Results of two-level HLM logistic (Bernoulli) models revealed that counselors with higher levels of education, larger caseloads, more buprenorphine-specific training, and less preference for 12-step treatment models were more likely to perceive buprenorphine as acceptable and effective. Furthermore, buprenorphine was 50% more likely to be perceived as effective among counselors working in CTN-affiliated programs as compared to private programs. This study suggests that research network affiliation positively impacts counselors’ acceptance and perceptions of buprenorphine. Thus, research network participation can be utilized as a means to promote positive attitudes toward the implementation of innovations including medication assisted treatment. PMID:24594902

    The Planning for Resilience in East Africa through Policy, Adaptation, Research, and Economic Development (PREPARED) is a multi-organizational project aimed at mainstreaming climate-resilient development planning and program implementation into the East African Community (EAC). The Famine Early Warning Systems Network (FEWS NET) has partnered with the PREPARED project to address three key development challenges for the EAC; 1) increasing resiliency to climate change, 2) managing trans-boundary freshwater biodiversity and conservation and 3) improving access to drinking water supply and sanitation services. USGS FEWS NET has been instrumental in the development of gridded climate data sets that are the fundamental building blocks for climate change adaptation studies in the region. Tools such as the Geospatial Climate Tool (GeoCLIM) have been developed to interpolate time-series grids of precipitation and temperature values from station observations and associated satellite imagery, elevation data, and other spatially continuous fields. The GeoCLIM tool also allows the identification of anomalies and assessments of both their frequency of occurrence and directional trends. A major effort has been put forth to build the capacities of local and regional institutions to use GeoCLIM to integrate their station data (which is not typically available to the public) into improved national and regional gridded climate data sets. In addition to the improvements and capacity building activities related to geospatial analysis tools, FEWS NET will assist in two other areas; 1) downscaling of climate change scenarios and 2) vulnerability impact assessments. FEWS NET will provide expertise in statistical downscaling of Global Climate Model output fields and work with regional institutions to assess results of other downscaling methods. Completion of a vulnerability impact assessment (VIA) involves the examination of sectoral consequences in identified climate "hot spots". FEWS NET

    In 1999 and 2002, the EURADOS Working Group on Environmental Monitoring organised two European intercomparison exercises of national network systems used to provide early warning in case of a nuclear accident. In total, 12 European countries, represented by more than 40 scientists, participated in these two intercomparisons with more than 35 different dose rate detectors. In addition, an in situ gamma spectrometry intercomparison was performed by a group of European scientists during the 2002 exercise. Results of these spectrometry measurements will be reported elsewhere. This report summarises the results of the second intercomparison, performed in 2002, at the environmental dosimetry facilities of the Physikalisch-Technische Bundesanstalt (PTB) in Germany. The unique combination of the ultra-low background Underground Laboratory (UDO) and two free-field sites (a floating platform on a lake showing an almost pure cosmic radiation field and a free-field gamma ray irradiation facility) provide the particular opportunity to precisely quantify the inherent background of the detectors and to calibrate them almost free of any background and traceable to PTB's primary standards. In addition, the intercomparison comprised investigations on the energy and dose rate dependence of the detectors' response to gamma radiation as well as on the response to cosmic radiation. Finally, the sensitivity of the detector systems to small dose rate variations, similar to that caused by a passing overhead radioactive plume, was studied under realistic free-field conditions. Following the Council Directive 96/29/EURATOM, the participants of the 2002 intercomparison were asked to report their results in terms of the operational quantity ambient dose equivalent, H(*)(10). Although the verification of the individual calibrations showed smaller discrepancies than those in the 1999 intercomparison, in a few cases, these discrepancies would be still unacceptably high in the case of a real

    The NSF-funded GAGE Facility, managed by UNAVCO, operates approximately ~1300 GNSS stations distributed across North and Central America and in the circum-Caribbean. Following community input starting in 2011 from several workshops and associated reports,UNAVCO has been exploring ways to increase the capability and utility of the geodetic resources under its management to improve our understanding in diverse areas of geophysics including properties of seismic, volcanic, magmatic and tsunami deformation sources. Networks operated by UNAVCO for the NSF have the potential to profoundly transform our ability to rapidly characterize events, provide rapid characterization and warning, as well as improve hazard mitigation and response. Specific applications currently under development include earthquake early warning, tsunami early warning, and tropospheric modeling with university, commercial, non-profit and government partners on national and international scales. In the case of tsunami early warning, for example, an RT-GNSS network can provide multiple inputs in an operational system starting with rapid assessment of earthquake sources and associated deformation, which leads to the initial model of ocean forcing and tsunami generation. In addition, terrestrial GNSScan provide direct measurements of the tsunami through the associated traveling ionospheric disturbance from several 100's of km away as they approach the shoreline,which can be used to refine tsunami inundation models. Any operational system like this has multiple communities that rely on a pan-Pacific real-time open data set. Other scientific and operational applications for high-rate GPS include glacier and ice sheet motions, tropospheric modeling, and better constraints on the dynamics of space weather. Combining existing data sets and user communities, for example seismic data and tide gauge observations, with GNSS and Met data products has proven complicated because of issues related to metadata

    Gender differences in vulnerability for cocaine addiction have been reported. Though the mechanisms are not understood, here we hypothesize that gender differences in reactivity to conditioned-cues, which contributes to relapse, are involved. To test this we compared brain metabolism (using PET and {sup 18}FDG) between female (n = 10) and male (n = 16) active cocaine abusers when they watched a neutral video (nature scenes) versus a cocaine-cues video. Self-reports of craving increased with the cocaine-cue video but responses did not differ between genders. In contrast, changes in whole brain metabolism with cocaine-cues differed by gender (p<0.05); females significantly decreased metabolism (-8.6% {+-} 10) whereas males tended to increase it (+5.5% {+-} 18). SPM analysis (Cocaine-cues vs Neutral) in females revealed decreases in frontal, cingulate and parietal cortices, thalamus and midbrain (p<0.001) whereas males showed increases in right inferior frontal gyrus (BA 44/45) (only at p<0.005). The gender-cue interaction showed greater decrements with Cocaine-cues in females than males (p<0.001) in frontal (BA 8, 9, 10), anterior cingulate (BA 24, 32), posterior cingulate (BA 23, 31), inferior parietal (BA 40) and thalamus (dorsomedial nucleus). Females showed greater brain reactivity to cocaine-cues than males but no differences in craving, suggesting that there may be gender differences in response to cues that are not linked with craving but could affect subsequent drug use. Specifically deactivation of brain regions from 'control networks' (prefrontal, cingulate, inferior parietal, thalamus) in females could increase their vulnerability to relapse since it would interfere with executive function (cognitive inhibition). This highlights the importance of gender tailored interventions for cocaine addiction.

    The U.S. Agency for International Development (USAID)'s Famine Early Warning System Network (FEWS NET) provides monitoring and early warning support to decision makers responsible for responding to food insecurity emergencies on three continents. FEWS NET uses satellite remote sensing and ground observations of rainfall and vegetation in order to provide information on drought, floods, and other extreme weather events to decision makers. Previous research has presented results from a professional review questionnaire with FEWS NET expert end-users whose focus was to elicit Earth observation requirements. The review provided FEWS NET operational requirements and assessed the usefulness of additional remote sensing data. We analyzed 1342 food security update reports from FEWS NET. The reports consider the biophysical, socioeconomic, and contextual influences on the food security in 17 countries in Africa from 2000 to 2009. The objective was to evaluate the use of remote sensing information in comparison with other important factors in the evaluation of food security crises. The results show that all 17 countries use rainfall information, agricultural production statistics, food prices, and food access parameters in their analysis of food security problems. The reports display large-scale patterns that are strongly related to history of the FEWS NET program in each country. We found that rainfall data were used 84% of the time, remote sensing of vegetation 28% of the time, and gridded crop models 10% of the time, reflecting the length of use of each product in the regions. More investment is needed in training personnel on remote sensing products to improve use of data products throughout the FEWS NET system.

    This background paper reviews current knowledge on warning systems and human response to warnings. It expands on an earlier paper prepared for a workshop on the Second Assessment on Natural Hazards, held in Estes Park, Colorado in July 1992. Although it has a North American perspective, many of the lessons learned are universally applicable. The paper addresses warning systems in terms of dissemination and does not cover physical science issues associated with prediction and forecast. Finally, it covers hazards with relatively short lead times -- 48 hours or less. It does not address topics such as long-term forecasts of earthquakes or volcanic eruptions or early famine warning systems.

    Operational meteorological centres around the world increasingly include warnings as one of their regular forecast products. Warnings are issued to warn the public about extreme weather situations that might occur leading to damages and losses. In forecasting these extreme events, meteorological centres help their potential users in preventing the damage or losses they might suffer. However, verifying these warnings requires specific methods. This is due not only to the fact that they happen rarely, but also because a new temporal dimension is added when defining a warning, namely the time window of the forecasted event. This paper analyses the issues that might appear when dealing with warning verification. It also proposes some new verification approaches that can be applied to wind warnings. These new techniques are later applied to a real life example, the verification of wind gust warnings at the German Meteorological Centre ("Deutscher Wetterdienst"). Finally, the results obtained from the latter are discussed.

    Underrepresentation in clinical trials limits the extent to which ethnic minorities benefit from advances in substance abuse treatment. The objective of this article is to share the knowledge gained within the Clinical Trials Network (CTN) of the National Institute on Drug Abuse and other research on recruiting and retaining ethnic minorities into substance abuse clinical trials. The article includes a discussion of two broad areas for improving inclusion— community involvement and cultural adaptation. CTN case studies are included to illustrate three promising strategies for improving ethnic minority inclusion: respondent-driven sampling, community-based participatory research, and the cultural adaptation of the recruitment and retention procedures. The article concludes with two sections describing a number of methodological concerns in the current research base and our proposed research agenda for improving ethnic minority inclusion that builds on the CTN experience.

    Background Training research staff to implement clinical trials occurring in community-based addiction treatment programs presents unique challenges. Standardized patient walkthroughs of study procedures may enhance training and protocol implementation. Objectives Examine and discuss cross-site and cross-study challenges of participant screening and data collection procedures identified during standardized patient walkthroughs of multi-site clinical trials. Method Actors portrayed clients and “walked through” study procedures with protocol research staff. The study completed 57 walkthroughs during implementation of 4 clinical trials. Results Observers and walkthrough participants identified three areas of concern (consent procedures, screening and assessment processes, and protocol implementation) and made suggestions for resolving the concerns. Conclusions and Scientific Significance Standardized patient walkthroughs capture issues with study procedures previously unidentified with didactic training or unscripted rehearsals. Clinical trials within the National Drug Abuse Treatment Clinical Trials Network are conducted in addiction treatment centers that vary on multiple dimensions. Based on walkthrough observations, the national protocol team and local site leadership modify standardized operating procedures and resolve cross-site problems prior to recruiting study participants. The standardized patient walkthrough improves consistency across study sites and reduces potential site variation in study outcomes. PMID:21854287

    The Group on Earth Observations' Global Agricultural Monitoring (GEOGLAM) implementation plan emphasizes the information needs of countries at risk of food insecurity emergencies. Countries in this category are often vulnerable to disruption of agricultural production due to drought, while at the same time they lack well developed networks of in-situ observations to support early drought detection. Consequently, it is vital that Earth observations by satellites supplement those available from surface stations. The USGS, in its role as a FEWS NET implementing partner, has recently developed a number of new applications of satellite observations for this purpose. (1) In partnership with the University of California, Santa Barbara, a 30+ year time series of gridded precipitation estimates (CHIRPS) has been developed by blending NOAA GridSat B1 geostationary thermal infrared imagery with station observations using robust geostatistical methods. The core data set consists of pentadal (5-daily) accumulations from 1981-2013 at 0.05 degree spatial resolution between +/- 50 degrees latitude. Validation has been recently completed, and applications for gridded crop water balance calculations and mapping the Standardized Precipitation Index are in development. (2) Actual evapotranspiration (ETa) estimates using MODIS Land Surface Temperature (LST) data at 1-km have been successfully demonstrated using the operational Simplified Surface Energy Balance model with 8-day composites from the LPDAAC. A new, next-day latency implementation using daily LST swath data from the NASA LANCE server is in development for all the crop growing regions of the world. This ETa processing chain follows in the footsteps of (3) the expedited production of MODIS 250-meter NDVI images every five days at USGS EROS, likewise using LANCE daily swath data as input since 2010. Coverage includes Africa, Central Asia, the Middle East, Central America, and the Caribbean. (4) A surface water point monitoring

    Introduction The majority of patients enrolled in treatment for substance use disorders (SUDs) also use tobacco. Many will continue to use tobacco even during abstinence from other drugs and alcohol, often leading to smoking-related illnesses. Despite this, little research has been conducted to assess the influence of being a smoker on SUD treatment outcomes and changes in smoking during a treatment episode. Methods In this secondary analysis, cigarette smoking was evaluated in participants completing outpatient SUD treatment as part of a multi-site study conducted by the National Drug Abuse Treatment Clinical Trials Network. Analyses included the assessment of changes in smoking and nicotine dependence via the Fagerström Test for Nicotine Dependence during the 12-week study among all smokers (Aim #1), specifically among those in the experimental treatment group (Aim #2), and the moderating effect of being a smoker on treatment outcomes (Aim #3). Results Participants generally did not reduce or quit smoking throughout the course of the study. Among a sub-set of participants with higher baseline nicotine dependence scores randomized to the control arm, scores at the end of treatment were lower compared to the experimental arm, though measures of smoking quantity did not appear to decrease. Further, being a smoker was associated with poorer treatment outcomes compared to non-smokers enrolled in the trial. Conclusions This study provides evidence that patients enrolled in community-based SUD treatment continue to smoke, even when abstaining from drugs and alcohol. These results add to the growing literature encouraging the implementation of targeted, evidence-based interventions to promote abstinence from tobacco among SUD treatment patients. PMID:25595301

    2015-01-01

    In June 2012, the Israeli government approved the offer of the creation of an earthquake early warning system (EEWS) that would provide timely alarms for schools and colleges in Israel. A network configuration was chosen, consisting of a staggered line of ˜100 stations along the main regional faults: the Dead Sea fault and the Carmel fault, and an additional ˜40 stations spread more or less evenly over the country. A hybrid approach to the EEWS alarm was suggested, where a P-wave-based system will be combined with the S-threshold method. The former utilizes first arrivals to several stations closest to the event for prompt location and determination of the earthquake's magnitude from the first 3 s of the waveform data. The latter issues alarms, when the acceleration of the surface movement exceeds a threshold for at least two neighboring stations. The threshold will be chosen to be a peak acceleration level corresponding to a magnitude 5 earthquake at a short distance range (5-10 km). The warning times or lead times, i.e., times between the alarm signal arrival and arrival of the damaging S-waves, are considered for the P, S, and hybrid EEWS methods. For each of the approaches, the P- and the S-wave travel times and the alarm times were calculated using a standard 1D velocity model and some assumptions regarding the EEWS data latencies. Then, a definition of alarm effectiveness was introduced as a measure of the trade-off between the warning time and the shaking intensity. A number of strong earthquake scenarios, together with anticipated shaking intensities at important targets, namely cities with high populations, are considered. The scenarios demonstrated in probabilistic terms how the alarm effectiveness varies depending on the target distance from the epicenter and event magnitude.

    Recent observations suggest the existence of clonazepam abuse. To determine its importance in France, a quantitative and systematic synthesis of all clonazepam data of several epidemiological tools of the Centers for Evaluation and Information on Pharmacodependence (CEIP) network has been performed in comparison with data on others benzodiazepines (BZD). Data on clonazepam and other BZD have been analysed from different epidemiological tools: OSIAP survey that identifies drugs obtained by means of falsified prescriptions, Observation of Illegal Drugs and Misuse of Psychotropic Medications (OPPIDUM) survey that describes modalities of use and data from regional French health reimbursement system. In OSIAP survey, the proportion of clonazepam falsified prescriptions among all BZD falsified prescriptions increased. During the 2006 OPPIDUM survey, the analysis of the BZD modalities of use highlights clonazepam abuse liability (for example 23% of illegal acquisition), in second rank after flunitrazepam. Studies based on data from the French health reimbursed system show that 1.5% of subjects with clonazepam dispensing had a deviant behaviour. Among BZD, clonazepam has the second most important doctor-shopping indicator (3%) after flunitrazepam. All these data provide some arguments in favour of clonazepam abuse liability in real life and the necessity to reinforce its monitoring.

    Spiritual abuse is the act of making people believe--whether by stating or merely implying--that they are going to be punished in this life and/or tormented in hell-fire forever for failure to live life good enough to please God and thus earn admission to heaven. Spiritual terrorism is the most extreme form of spiritual abuse and may cause serious mental health problems. Those people who have not been spiritually terrorized have not necessarily been spared from spiritual abuse and therefore may still be in need of competent, spiritual counseling. Spiritual abuse, which may be active or passive, can best be conceptualized on a continuum from terroristic to zero abuse. Severity is determined by intensity, age of onset, duration, and individual reaction. The underlying issue in all forms of abuse is control. PMID:9729974

    The 9.1 Mw Great Sumatra Earthquake of Dec. 26, 2004, generated the most destructive tsunami in history killing 227,000 people along Indian Ocean coastlines and was recorded by sea-level instruments world-wide. This tragedy showed the Indian Ocean needed a tsunami warning system to prevent another tragedy on this scale. The Great Sumatra Earthquake also highlighted the need for tsunami warning systems in other ocean basins. Instruments for recording earthquakes and sea-level data useful for tsunami monitoring did not exist outside of the Pacific Ocean in 2004. Seismometers were few in number, and even fewer were high-quality long period broadband instruments. Nor was much of their data made available to the US tsunami warning centers (TWCs). In 2004 the US TWCs relied exclusively on instrumentation provided and maintained by IRIS and the USGS for areas outside of the Pacific.Since 2004, the US TWCs and their partners have made substantial improvements to seismic and sea-level monitoring networks with the addition of new and better instruments, densification of existing networks, better communications infrastructure, and improved data sharing among tsunami warning centers. In particular, the number of sea-level stations transmitting data in near real-time and the amount of seismic data available to the tsunami warning centers has more than tripled. The DART network that consisted of a half-dozen Pacific stations in 2004 now totals nearly 60 stations worldwide. Earthquake and tsunami science has progressed as well. It took nearly three weeks to obtain the first reliable estimates of the 2004 Sumatra Earthquake's magnitude. Today, thanks to improved seismic networks and modern computing power, TWCs use the W-phase seismic moment method to determine accurate earthquake magnitudes and focal mechanisms for great earthquakes within 25 minutes. TWC scientists have also leveraged these modern computers to generate tsunami forecasts in a matter of minutes.Progress towards a

    Tsunami warning and watch services are currently provided to the Caribbean region through a collaborative effort between the two NOAA Tsunami Warning Centers (TWCs): the Pacific Tsunami Warning Center (PTWC) in Ewa Beach, Hawaii, and the West Coast/Alaska Tsunami Warning Center (WCATWC) in Palmer, Alaska. The WCATWC, in coordination with the Puerto Rico Seismic Network (PRSN), provides fast-response warning services to the U.S. territories of the Commonwealth of Puerto Rico and the U.S. Virgin Islands (PR/VI). The PTWC provides regional watch services to other countries throughout and surrounding the Caribbean Sea as part of the Intergovernmental Coordination Group for the Caribbean Sea and Adjacent Regions. This collaboration is analogous to the TWC's responsibilities in the Pacific basin: the WCATWC provides fast-response warning services for the U.S. west coast states, Alaska, and British Columbia in Canada, while the PTWC provides regional services for countries throughout and surrounding the Pacific Ocean (as well as a fast-response service for the U.S. State of Hawaii). Caribbean seismic data are transmitted to the TWCs through several means. The PRSN directly exports data to the WCATWC, providing the Center sufficient seismic data for the PR/VI region. Additionally, the PRSN provides the TWCs with data gathered from other Caribbean nations. Using modern communication capabilities, the seismic data can be processed at the TWCs at the same time it is processed locally. Another source of high- quality seismic data is the new USGS nine-station array that circles the region. The Global Seismic Network maintains several stations in Caribbean, Central American, and South American nations which are available in real-time to the TWCs. Unfortunately, sea level data coverage is sporadic in the region. The PR/VI has a relatively dense array of coastal tide gages, but coastal tide gage coverage is very sparse for the rest of the Caribbean basin. Three deep-ocean pressure

    It is virtually certain (probability>99%) that the next destructive NEO event will be an airburst. Planetary defense is usually assumed to have the primary goal of maximizing the number of lives saved, but it can be argued that more emphasis should be placed on maximizing the probability of saving lives. For the latter goal, it is far more effective to create an early warning and civil defense plan than a mitigation plan that involves deflecting a large NEO. Because early warning and civil defense will almost certainly be needed long before the first deflection is ever required, the credibility of the planetary defense community and its recommendations will be put to its first serious test by an airburst. Successful response to an airburst event will make it much more likely that recommendations for mitigation by deflection will be accepted by decision makers and the public. Focusing more attention on the second goal will, as a side effect, benefit the primary goal.

    Background Rates of prescription drug abuse have reached epidemic proportions. Large-scale epidemiologic surveys of this under-recognized clinical problem have not included antidepressants despite their contribution to morbidity and mortality. The purpose of this review is to look specifically at the misuse of antidepressants and how this behavior may fit into the growing crisis of nonmedical use of prescription drugs. Methods We conducted a comprehensive search on PubMed, Medline, and PsycINFO using the search terms “antidepressant”, “abuse”, “misuse”, “nonmedical use”, “dependence”, and “addiction”, as well as individual antidepressant classes (eg, “SSRI”) and individual antidepressants (eg, “fluoxetine”) in various combinations, to identify articles of antidepressant misuse and abuse. Results A small but growing literature on the misuse and abuse of antidepressants consists largely of case reports. Most cases of antidepressant abuse have occurred in individuals with comorbid substance use and mood disorders. The most commonly reported motivation for abuse is to achieve a psychostimulant-like effect. Antidepressants are abused at high doses and via a variety of routes of administration (eg, intranasal, intravenous). Negative consequences vary based upon antidepressant class and pharmacology, but these have included seizures, confusion, and psychotic-like symptoms. Conclusion The majority of individuals prescribed antidepressants do not misuse the medication. However, certain classes of antidepressants do carry abuse potential. Vulnerable patient populations include those with a history of substance abuse and those in controlled environments. Warning signs include the presence of aberrant behaviors. Physicians should include antidepressants when screening for risky prescription medication use. When antidepressant misuse is detected, a thoughtful treatment plan, including referral to an addiction specialist, should be developed and

  8. Systems and Sensors for Debris-flow Monitoring and Warning

    PubMed Central

    Arattano, Massimo; Marchi, Lorenzo

    2008-01-01

    Debris flows are a type of mass movement that occurs in mountain torrents. They consist of a high concentration of solid material in water that flows as a wave with a steep front. Debris flows can be considered a phenomenon intermediate between landslides and water floods. They are amongst the most hazardous natural processes in mountainous regions and may occur under different climatic conditions. Their destructiveness is due to different factors: their capability of transporting and depositing huge amounts of solid materials, which may also reach large sizes (boulders of several cubic meters are commonly transported by debris flows), their steep fronts, which may reach several meters of height and also their high velocities. The implementation of both structural and non-structural control measures is often required when debris flows endanger routes, urban areas and other infrastructures. Sensor networks for debris-flow monitoring and warning play an important role amongst non-structural measures intended to reduce debris-flow risk. In particular, debris flow warning systems can be subdivided into two main classes: advance warning and event warning systems. These two classes employ different types of sensors. Advance warning systems are based on monitoring causative hydrometeorological processes (typically rainfall) and aim to issue a warning before a possible debris flow is triggered. Event warning systems are based on detecting debris flows when these processes are in progress. They have a much smaller lead time than advance warning ones but are also less prone to false alarms. Advance warning for debris flows employs sensors and techniques typical of meteorology and hydrology, including measuring rainfall by means of rain gauges and weather radar and monitoring water discharge in headwater streams. Event warning systems use different types of sensors, encompassing ultrasonic or radar gauges, ground vibration sensors, videocameras, avalanche pendulums

  10. Tsunami warnings: Understanding in Hawai'i

    The devastating southeast Asian tsunami of December 26, 2004 has brought home the destructive consequences of coastal hazards in an absence of effective warning systems. Since the 1946 tsunami that destroyed much of Hilo, Hawai'i, a network of pole mounted sirens has been used to provide an early public alert of future tsunamis. However, studies in the 1960s showed that understanding of the meaning of siren soundings was very low and that ambiguity in understanding had contributed to fatalities in the 1960 tsunami that again destroyed much of Hilo. The Hawaiian public has since been exposed to monthly tests of the sirens for more than 25 years and descriptions of the system have been widely published in telephone books for at least 45 years. However, currently there remains some uncertainty in the level of public understanding of the sirens and their implications for behavioral response. Here, we show from recent surveys of Hawai'i residents that awareness of the siren tests and test frequency is high, but these factors do not equate with increased understanding of the meaning of the siren, which remains disturbingly low (13%). Furthermore, the length of time people have lived in Hawai'i is not correlated systematically with understanding of the meaning of the sirens. An additional issue is that warning times for tsunamis gene rated locally in Hawai'i will be of the order of minutes to tens of minutes and limit the immediate utility of the sirens. Natural warning signs of such tsunamis may provide the earliest warning to residents. Analysis of a survey subgroup from Hilo suggests that awareness of natural signs is only moderate, and a majority may expect notification via alerts provided by official sources. We conclude that a major change is needed in tsunami education, even in Hawai'i, to increase public understanding of, and effective response to, both future official alerts and natural warning signs of future tsunamis. ??

    Earthquake early warning (EEW) can reduce harm to people and infrastructure from earthquakes and tsunamis, but it has not been implemented in most high earthquake-risk regions because of prohibitive cost. Common consumer devices such as smartphones contain low-cost versions of the sensors used in EEW. Although less accurate than scientific-grade instruments, these sensors are globally ubiquitous. Through controlled tests of consumer devices, simulation of an M w (moment magnitude) 7 earthquake on California's Hayward fault, and real data from the M w 9 Tohoku-oki earthquake, we demonstrate that EEW could be achieved via crowdsourcing.

    Although earthquake early warning (EEW) has shown great promise for reducing loss of life and property, it has only been implemented in a few regions due, in part, to the prohibitive cost of building the required dense seismic and geodetic networks. However, many cars and consumer smartphones, tablets, laptops, and similar devices contain low-cost versions of the same sensors used for earthquake monitoring. If a workable EEW system could be implemented based on either crowd-sourced observations from consumer devices or very inexpensive networks of instruments built from consumer-quality sensors, EEW coverage could potentially be expanded worldwide. Controlled tests of several accelerometers and global navigation satellite system (GNSS) receivers typically found in consumer devices show that, while they are significantly noisier than scientific-grade instruments, they are still accurate enough to capture displacements from moderate and large magnitude earthquakes. The accuracy of these sensors varies greatly depending on the type of data collected. Raw coarse acquisition (C/A) code GPS data are relatively noisy. These observations have a surface displacement detection threshold approaching ~1 m and would thus only be useful in large Mw 8+ earthquakes. However, incorporating either satellite-based differential corrections or using a Kalman filter to combine the raw GNSS data with low-cost acceleration data (such as from a smartphone) decreases the noise dramatically. These approaches allow detection thresholds as low as 5 cm, potentially enabling accurate warnings for earthquakes as small as Mw 6.5. Simulated performance tests show that, with data contributed from only a very small fraction of the population, a crowd-sourced EEW system would be capable of warning San Francisco and San Jose of a Mw 7 rupture on California's Hayward fault and could have accurately issued both earthquake and tsunami warnings for the 2011 Mw 9 Tohoku-oki, Japan earthquake.

    The need to use early warning methods to reduce natural risks in modern societies is related to their unprecedented dependence upon technology. The strong deep events originating from Vrancea-Romania (Mw =7.5) area and shallow events originating from Banat-Romania or Shabla-Bulgaria areas can generate destructive effects in Romania and neighbor countries, and may seriously affect high risk manmade structures. EWS for deep Vrancea earthquakes uses the time interval (28-32 sec.) between the moment when the earthquake is detected by the local seismic network installed in the epicenter area (Vrancea) and the arrival time of the seismic waves in the protected area (Bucharest) to send earthquake warning to users. For the shallow events several methodologies to rapidly estimate earthquake magnitude are under testing. NIEP developed an early warning system that is able to evaluate rapidly earthquake magnitude after detection in the epicenter. In the last years, NIEP upgraded its seismic network in order to cover better the seismic zones of Romania. The early warning system consists of seismic stations that allow rapid communication of data, several software modules developed at NIEP and a communication network. The system allows estimation of earthquake magnitude and permits to send earthquake alarm very fast to users. The early warning software modules minimize communication latencies present in other communication protocols in order to have a rapid magnitude determination. This software was developed by NIEP and is running in present at our institute in real time.

    Tsunamis are high-impact disasters that can cause death and destruction locally within a few minutes of their occurrence and across oceans hours, even up to a day, afterward. Efforts to establish tsunami warning systems to protect life and property began in the Pacific after the 1946 Aleutian Islands tsunami caused casualties in Hawaii. Seismic and sea level data were used by a central control center to evaluate tsunamigenic potential and then issue alerts and warnings. The ensuing events of 1952, 1957, and 1960 tested the new system, which continued to expand and evolve from a United States system to an international system in 1965. The Tsunami Warning System in the Pacific (ITSU) steadily improved through the decades as more stations became available in real and near-real time through better communications technology and greater bandwidth. New analysis techniques, coupled with more data of higher quality, resulted in better detection, greater solution accuracy, and more reliable warnings, but limitations still exist in constraining the source and in accurately predicting propagation of the wave from source to shore. Tsunami event data collected over the last two decades through international tsunami science surveys have led to more realistic models for source generation and inundation, and within the warning centers, real-time tsunami wave forecasting will become a reality in the near future. The tsunami warning system is an international cooperative effort amongst countries supported by global and national monitoring networks and dedicated tsunami warning centers; the research community has contributed to the system by advancing and improving its analysis tools. Lessons learned from the earliest tsunamis provided the backbone for the present system, but despite 45 years of experience, the 2004 Indian Ocean tsunami reminded us that tsunamis strike and kill everywhere, not just in the Pacific. Today, a global intergovernmental tsunami warning system is coordinated

The objective of these efforts is to develop innovative concepts and advanced algorithms that enhance our national Chemical Warfare (CW) test and warning capabilities via the fusion of traditional and non-traditional CW sensor data. Under Phase I, II, and III Small Business Innovative Research (SBIR) contracts with DPG, Torch developed the Advanced Chemical Release Evaluation System (ACRES) software to support non real-time CW sensor data fusion. Under Phase I and II SBIRs with DTRA in conjunction with the Edgewood Chemical Biological Center (ECBC), Torch is using the DPG ACRES CW sensor data fuser as a framework from which to develop the Cloud state Estimation in a Networked Sensor Environment (CENSE) data fusion system. Torch is currently developing CENSE to implement and test innovative real-time sensor network based data fusion concepts using CW and non-CW ancillary sensor data to improve CW warning and detection in tactical scenarios.

  19. Are heat warning systems effective?

    PubMed Central

    2013-01-01

    Heatwaves are associated with significant health risks particularly among vulnerable groups. To minimize these risks, heat warning systems have been implemented. The question therefore is how effective these systems are in saving lives and reducing heat-related harm. We systematically searched and reviewed 15 studies which examined this. Six studies asserted that fewer people died of excessive heat after the implementation of heat warning systems. Demand for ambulance decreased following the implementation of these systems. One study also estimated the costs of running heat warning systems at US$210,000 compared to the US$468 million benefits of saving 117 lives. The remaining eight studies investigated people’s response to heat warning systems and taking appropriate actions against heat harms. Perceived threat of heat dangers emerged as the main factor related to heeding the warnings and taking proper actions. However, barriers, such as costs of running air-conditioners, were of significant concern, particularly to the poor. The weight of the evidence suggests that heat warning systems are effective in reducing mortality and, potentially, morbidity. However, their effectiveness may be mediated by cognitive, emotive and socio-demographic characteristics. More research is urgently required into the cost-effectiveness of heat warning systems’ measures and improving the utilization of the services. PMID:23561265

    With more direct, personal warning systems becoming popular, the continued maintenance of older warning systems, such as outdoor warning sirens, may be jeopardized as emergency managers (EMs) seek to optimize their limited budgets. However, the extent to which sirens are embedded into the American landscape and culture argues against their removal. To better quantify the distribution and use of outdoor warning sirens, an international survey of EMs was conducted to learn more about where siren systems are deployed and how they are operated. Approximately 593 respondents started the 31 question survey with 383 completing it. Questions were asked regarding siren network size, alternative warning systems, siren use and capabilities, and testing. For those without sirens, a series of questions were asked for why sirens were not used. In general, a lack of perceived threat, high costs, and large geographic area kept some jurisdictions from installing sirens. Of those that operate siren networks, half of networks are small (≤10 sirens), while a small percentage of jurisdictions (6.3 percent) operate very large networks (>100). A large majority of respondents expected to maintain or expand their networks within the next 5 years. Three-quarters of respondents use additional warning systems. Nearly half of respondents use sirens for nonweather applications, and nearly two-thirds have the capability to use multiple sound alerts. Overall, sirens remain a popular tool for warning on a variety of local hazards though how the sirens are operated and tested vary widely by jurisdiction.

    New turbulence prediction technology offers the potential for advance warning of impending turbulence encounters, thereby allowing necessary cabin preparation time prior to the encounter. The amount of time required for passengers and flight attendants to be securely seated (that is, seated with seat belts fastened) currently is not known. To determine secured seating-based warning times, a consortium of aircraft safety organizations have conducted an experiment involving a series of timed secured seating trials. This demonstrative experiment, conducted on October 1, 2, and 3, 2002, used a full-scale B-747 wide-body aircraft simulator, human passenger subjects, and supporting staff from six airlines. Active line-qualified flight attendants from three airlines participated in the trials. Definitive results have been obtained to provide secured seating-based warning times for the developers of turbulence warning technology

  10. Earthquake early warning system using real-time signal processing

    SciTech Connect

    Leach, R.R. Jr.; Dowla, F.U.

    1996-02-01

    An earthquake warning system has been developed to provide a time series profile from which vital parameters such as the time until strong shaking begins, the intensity of the shaking, and the duration of the shaking, can be derived. Interaction of different types of ground motion and changes in the elastic properties of geological media throughout the propagation path result in a highly nonlinear function. We use neural networks to model these nonlinearities and develop learning techniques for the analysis of temporal precursors occurring in the emerging earthquake seismic signal. The warning system is designed to analyze the first-arrival from the three components of an earthquake signal and instantaneously provide a profile of impending ground motion, in as little as 0.3 sec after first ground motion is felt at the sensors. For each new data sample, at a rate of 25 samples per second, the complete profile of the earthquake is updated. The profile consists of a magnitude-related estimate as well as an estimate of the envelope of the complete earthquake signal. The envelope provides estimates of damage parameters, such as time until peak ground acceleration (PGA) and duration. The neural network based system is trained using seismogram data from more than 400 earthquakes recorded in southern California. The system has been implemented in hardware using silicon accelerometers and a standard microprocessor. The proposed warning units can be used for site-specific applications, distributed networks, or to enhance existing distributed networks. By producing accurate, and informative warnings, the system has the potential to significantly minimize the hazards of catastrophic ground motion. Detailed system design and performance issues, including error measurement in a simple warning scenario are discussed in detail.

    Warning systems commonly use information provided by networks of sensors able to monitor and detect impending disasters, aggregate and condense these information to provide reliable information to a decision maker whether to warn or not, disseminates the warning message and provide this information to people at risk. Ultimate aim is to enable those in danger to make decisions (e.g. initiate protective actions for buildings) and to take action to safe their lives. This involves very complex issues when considering all four elements of early warning systems (UNISDR-PPEW), namely (1) risk knowledge, (2) monitoring and warning service, (3) dissemination and communication, (4) response capability with the ultimate aim to gain as much time as possible to empower individuals and communities to act in an appropriate manner to reduce injury, loss of life, damage to property and the environment and loss of livelihoods. Commonly most warning systems feature strengths and main attention on the technical/structural dimension (monitoring & warning service, dissemination tools) with weaknesses and less attention on social/cultural dimension (e.g. human response capabilities, defined warning chain to and knowing what to do by the people). Also, the use of risk knowledge in early warning most often is treated in a theoretical manner (knowing that it is somehow important), yet less in an operational, practical sense. Risk assessments and risk maps help to motivate people, prioritise early warning system needs and guide preparations for response and disaster prevention activities. Beyond this risk knowledge can be seen as a tie between national level early warning and community level reaction schemes. This presentation focuses on results, key findings and lessons-learnt related to tsunami risk assessment in the context of early warning within the GITEWS (German-Indonesian Tsunami Early Warning) project. Here a novel methodology reflecting risk information needs in the early warning

    We have designed a compact, wireless, GPS-enabled array of inexpensive radiation sensors based on scintillation counting. Each sensor has a scintillator, photomultiplier tube, and pulse-counting circuit that includes a comparator, digital potentiometer and microcontroller. This design provides a high level of sensitivity and reliability. A 0.2 m2 PV panel powers each sensor providing a maintenance-free 24/7 energy source. The sensor can be mounted within a roadway light-post and monitor radiological activity along transport routes. Each sensor wirelessly transmits real-time data (as counts per second) up to 2 miles with a XBee radio module, and the data is received by a XBee receive-module on a computer. Data collection software logs the information from all sensors and provides real-time identification of radiation events. Measurements performed to-date demonstrate the ability of a sensor to detect a 20 μCi source at 3.5 meters when packaged with a PVT (plastic) scintillator, and 7 meters for a sensor with a CsI crystal (more expensive but ~5 times more sensitive). It is calculated that the sensor-architecture can detect sources moving as fast as 130 km/h based on the current data rate and statistical bounds of 3-sigma threshold detection. The sensor array is suitable for identifying and tracking a radiation threat from a dirty bomb along roadways.

    Recruiting and retaining clients in health interventions can be challenging especially when targeting multiple behavior change in high-risk populations. To inform the methods of trials working with similarly complex clinical populations, we describe multi-pronged efforts to recruit and retain a representative sample. In a two-group RCT, veterans were recruited from a Veteran Affairs Medical Center. The goal was to enroll 200 participants over a 25-month period, and to exceed 70 % follow-up for all treatment arms. To meet these goals, a four-pronged strategy was developed: branding, outreach/networking, onsite presence, and incentives. In month 1, 32 % of the proposed sample size was met (n = 64), and by month 2, 45 % (n = 90); the recruitment goal (n = 200) was achieved 13 months ahead of schedule. Retention exceeds 90 % at all time points out to 18 months. The multipronged recruitment and retention plan was efficient, cost effective, and may generalize to other health promotion initiatives.

    2005-01-01

    Aims The clinical effectiveness of buprenorphine–naloxone (bup-nx) and clonidine for opioid detoxification in in-patient and out-patient community treatment programs was investigated in the first studies of the National Institute of Drug Abuse Clinical Trials Network. Design Diagnostic and Statistical Manual version IV (DSM IV)-diagnosed opioid-dependent individuals seeking short-term treatment were randomly assigned, in a 2:1 ratio favoring bup-nx, to a 13-day detoxification using bup-nx or clonidine. Methods A total of 113 in-patients (77 bup-nx, 36 clonidine) and 231 out-patients (157 bup-nx, 74 clonidine) participated. Supportive interventions included appropriate ancillary medications and standard counseling procedures guided by a self-help handbook. The criterion for treatment success was defined as the proportion of participants in each condition who were both retained in the study for the entire duration and provided an opioid-free urine sample on the last day of clinic attendance. Secondary outcome measures included use of ancillary medications, number of side effects reported and withdrawal and craving ratings. Findings A total of 59 of the 77 (77%) in-patients assigned to the bup-nx condition achieved the treatment success criterion compared to eight of the 36 (22%) assigned to clonidine, whereas 46 of the 157 (29%) out-patients assigned to the bup-nx condition achieved the treatment success criterion, compared to four of the 74 (5%) assigned to clonidine. Conclusion The benefits of bup-nx for opioid detoxification are supported and illustrate important ways in which clinical research can be conducted in community treatment programs. PMID:16042639

    The natural disaster of the Boxing Day Tsunami of 2004 was followed by an information catastrophe. Crucial early warning information could not be delivered to the communities under imminent threat, resulting in over 240,000 casualties in 14 countries. This tragedy sparked the development of a new generation of integrated modular Tsunami Early Warning Systems (TEWS). While significant advances were accomplished in the past years, recent events, like the Chile 2010 and the Tohoku 2011 tsunami demonstrate that the key technical challenge for Tsunami Early Warning research on the supranational scale still lies in the timely issuing of status information and reliable early warning messages in a proven workflow. A second challenge stems from the main objective of the Intergovernmental Oceanographic Commission of UNESCO (IOC) Tsunami Programme, the integration of national TEWS towards ocean-wide networks: Each of the increasing number of integrated Tsunami Early Warning Centres has to cope with the continuing evolution of sensors, hardware and software while having to maintain reliable inter-center information exchange services. To avoid future information catastrophes, the performance of all components, ranging from individual sensors, to Warning Centers within their particular end-to-end Warning System Environments, and up to federated Systems of Tsunami Warning Systems has to be regularly validated against defined criteria. Since 2004, GFZ German Research Centre for Geosciences (GFZ) has built up expertise in the field of TEWS. Within GFZ, the Centre for GeoInformation Technology (CeGIT) has focused its work on the geoinformatics aspects of TEWS in two projects already, being the German Indonesian Tsunami Early Warning System (GITEWS) and the Distant Early Warning System (DEWS). This activity is continued in the TRIDEC project (Collaborative, Complex, and Critical Decision Processes in Evolving Crises) funded under the European Union's seventh Framework Programme (FP7

    Background Prevention strategies to reduce alcohol use/consumption among young people are crucial to reducing alcohol-related deaths and preventing disease. This paper focuses on the effectiveness of a social networking site (SNS) alcohol prevention program targeted toward young people. Objective We hypothesized that the program would diminish the relation made by participants between alcohol and festive moments, and would result in a reduction of their declared consumption of alcohol at festive moments during the program. We also explored the interaction with the prevention program that was the most efficient. Methods The prevention program took the form of 3 lotteries over 2 years. The participants periodically received prevention messages, particularly on alcohol and festive moments (eg, videos on Facebook and short message service [SMS] text messages on their mobile phones). For the 3 periods, the participants had to answer questions exploring the level of their belief that alcohol consumption and festive moments are highly associated. A control group that did not participate in the prevention program was asked the same questions over the same number of days for the first 2 periods. During the second period, the participants were asked to answer questions about their alcohol consumption during parties. During the third period, we explored the interaction with the prevention program on the reduction of their belief that alcohol consumption and festive moments are associated. Results A total of 651 participants (age: mean 22.24, SD 4.10 years; women: n=430) during the first period, 301 participants (age: mean 21.27, SD 3.07 years; women n=199) during the second period, and 305 (age: mean 22.41, SD 4.65 years; women: n=190) during the third period correctly completed the survey. For the control group, 69 students completed the survey during the first period (age: mean 18.93, SD 1.14 years; women: n=59) and 50 during the second (age: mean 20.78, SD 1.94 years

    Abuse of anabolic-androgenic steroids (AAS) by members of fitness centers and others in Germany has reached alarming dimensions. The health care system provides the illegal AAS to 48.1 % of abusers. Physicians are involved in illegal prescription of AAS and monitoring of 32.1 % of AAS abusers. Besides health-threatening cardiovascular, hepatotoxic and psychiatric long-term side effects of AAS, acne occurs in about 50 % of AAS abusers and is an important clinical indicator of AAS abuse, especially in young men 18-26 years of age. Both acne conglobata and acne fulminans can be induced by AAS abuse. The dermatologist should recognize bodybuilding acne, address the AAS abuse, and warn the patient about other potential hazards.

  4. Application of Seismic Array Processing to Tsunami Early Warning

    2015-12-01

    Tsunami wave predictions of the current tsunami warning systems rely on accurate earthquake source inversions of wave height data. They are of limited effectiveness for the near-field areas since the tsunami waves arrive before data are collected. Recent seismic and tsunami disasters have revealed the need for early warning to protect near-source coastal populations. In this work we developed the basis for a tsunami warning system based on rapid earthquake source characterisation through regional seismic array back-projections. We explored rapid earthquake source imaging using onshore dense seismic arrays located at regional distances on the order of 1000 km, which provides faster source images than conventional teleseismic back-projections. We implement this method in a simulated real-time environment, and analysed the 2011 Tohoku earthquake rupture with two clusters of Hi-net stations in Kyushu and Northern Hokkaido, and the 2014 Iquique event with the Earthscope USArray Transportable Array. The results yield reasonable estimates of rupture area, which is approximated by an ellipse and leads to the construction of simple slip models based on empirical scaling of the rupture area, seismic moment and average slip. The slip model is then used as the input of the tsunami simulation package COMCOT to predict the tsunami waves. In the example of the Tohoku event, the earthquake source model can be acquired within 6 minutes from the start of rupture and the simulation of tsunami waves takes less than 2 min, which could facilitate a timely tsunami warning. The predicted arrival time and wave amplitude reasonably fit observations. Based on this method, we propose to develop an automatic warning mechanism that provides rapid near-field warning for areas of high tsunami risk. The initial focus will be Japan, Pacific Northwest and Alaska, where dense seismic networks with the capability of real-time data telemetry and open data accessibility, such as the Japanese HiNet (>800

    The U.S. Geological Survey (USGS) and partners are transitioning from test-user trials of a demonstration earthquake early warning system (ShakeAlert) to deciding and preparing how to implement the release of earthquake early warning information, alert messages, and products to the public and other stakeholders. An earthquake early warning system uses seismic station networks to rapidly gather information about an occurring earthquake and send notifications to user devices ahead of the arrival of potentially damaging ground shaking at their locations. Earthquake early warning alerts can thereby allow time for actions to protect lives and property before arrival of damaging shaking, if users are properly educated on how to use and react to such notifications. A collaboration team of risk communications researchers and earth scientists is researching the effectiveness of a chosen subset of potential earthquake early warning interface designs and messages, which could be displayed on a device such as a smartphone. Preliminary results indicate, for instance, that users prefer alerts that include 1) a map to relate their location to the earthquake and 2) instructions for what to do in response to the expected level of shaking. A number of important factors must be considered to design a message that will promote appropriate self-protective behavior. While users prefer to see a map, how much information can be processed in limited time? Are graphical representations of wavefronts helpful or confusing? The most important factor to promote a helpful response is the predicted earthquake intensity, or how strong the expected shaking will be at the user's location. Unlike Japanese users of early warning, few Californians are familiar with the earthquake intensity scale, so we are exploring how differentiating instructions between intensity levels (e.g., "Be aware" for lower shaking levels and "Drop, cover, hold on" at high levels) can be paired with self-directed supplemental

    of snow avalanches) or trigger events (e.g. heavy snow fall) to predict spontaneous hazard events in advance. They encompass regional or national measuring networks and satisfy additional demands such as the standardisation of the measuring stations. The developed classification and the characteristics, which were revealed for each class, yield a valuable input to quantifying the reliability of warning and alarm systems. Importantly, this will facilitate to compare them with well-established standard mitigation measures such as dams, nets and galleries within an integrated risk management approach.

    When large earthquake occurs, earthquake early warning (EEW) provides alerts to urban areas of the forthcoming strong ground shaking. Depending on the specific geometry of the epicenter and the strong motion network used in EEW, the warning time can be a few seconds to tens of seconds. This warning time can be extremely important since even a few seconds can be sufficient for pre-programmed systems to have emergency response. The Central Weather Bureau (CWB) had already used network EEW system to predict intensity map. Due to leveling of intensity was roughly divided into seven grades according to peak acceleration (PGA) in Taiwan, the warning message is not cautious for company, home and school use, the accuracy of predicted PGA were discuss for our result. A practical site correction approach for EEW was constructed in this study. Period parameter (τc) and an amplitude parameter (Pd)from the initial 3 seconds of P waves were calculated after Wu et al.(2005) first for each site of Taiwan Strong-Motion Instrumentation Program (TSMIP) in Ilan, Taiwan for focal depths less than 35 km and magnitude Mw>=5.0. Two pairs of linear relations had showed in each station between τc, magnitude (Mw) and Pd, hypocenter distance (R) that could be corrected individually. Prediction results of PGA from site correction based ground motion prediction equation (Jean et al. 2006) indicated that the corrected parameters of EEW in this study had improved the accuracy of ground motion prediction. Which means reasonable site correction of each station was needed for EEW system. Key works: earthquake early warning, P wave, site correction

    Landslide early warning systems are a good choice if hazards cannot be avoided or if remedial actions are too costly or impossible. Landslide early warning systems are often site-specific and cannot easily be transferred to other regions or even to other landslide processes. One of the main goals of the ILEWS project is the development of transferable early warning concepts starting by the sensor in field and modelling early warning, and ending with user-optimized action advises embedded in a holistic risk management strategy. In our presentation we discuss five landslide early warning models applied in the ILEWS project of which four are aiming at the local scale and single slopes and one at the regional scale. The local study area is located on an extremely slow moving complex rotational landslide in the Swabian Alb, southwest Germany. A slow moving landslide was chosen to ensure that monitoring equipment does not get destroyed before the developed models can be tested extensively. A monitoring system with inclinometers, geoelectric profiles, TDR sensors and tensiometers, a geodetic network and a weather station was installed on the slope and data is utilized in the consequent early warning modelling. The regional model was applied to the Swabian Alb and to the region of South Tyrol, Northern Italy. The first local model is based the physically-based slope stability program CHASM (Combined Hydrology and Stability Model). Slope stability is continuously calculated on a web-processing service. Further on, registered users can create their personal simulations by selecting individual profiles by clicking on a map, and choosing scenarios for rainfall and slope moisture. A second model applies the concept of progressive failure to the slope. Warning is issued when a sudden increase in movement speed is reported by a stationary inclinometer chain. The third model utilizes the analysis of critical thresholds initiating movements. Definition of these thresholds is based

    2003-10-01

    Elder neglect and abuse represent a widespread, largely undiagnosed problem in the United States. Factors contributing to misdiagnosis and underreporting include denial by both the victim and the perpetrator, clinicians' reluctance to report victims, disbelief by medical providers, and clinicians' lack of awareness of warning signs. Physical abuse is most recognizable, yet neglect is most common. Psychological and financial abuse may be more easily missed. Elder neglect and abuse have many clinical presentations, ranging from the overt appearance of bruises and fractures, to the subtle appearance of dehydration, depression, and apathy. Risk factors are varied and may be categorized by victim or perpetrator. Dependency, on the part of the victim or perpetrator, and caregiver stress are frequent common denominators in abusive situations. Increasingly, Institutionalization is recognized as a risk factor for neglect and abuse. Most states require primary care providers to report suspected elder abuse. Awareness of the risk factors and clinical manifestations allows primary care physicians to provide early detection and intervention for elder neglect and abuse. PMID:14569641

    This paper overviews the controversies surrounding the abuse of prescription analgesic OxyContin® (oxycodone hydrochloride; Purdue Pharma, Stamford, CT, USA). It discusses solutions to this medication-related issue, which has been touted as reaching epidemic proportions. Relevant literature from 1990 to 2004 was identified through a MEDLINE search, and a thorough internet-based search was conducted to obtain the latest updates and government reports. OxyContin became popular as a street drug through its ability to induce a quick heroin-like euphoria. The media hype surrounding OxyContin abuse and the “black box” warning on its label may have added to the abuse and diversion. The US Food and Drug Administration took steps by writing letters to Purdue Pharma, the manufacturers of OxyContin. Purdue Pharma developed a database to identify OxyContin abusers throughout the nation and also launched campaigns to educate patients through the internet. Further suggestions to managing the abuse of OxyContin include: community pharmacists’ assessment of behavioral risk factors that could lead to patient medication abuse; medication abuse risk management courses for physicians; development of a national database linking all pharmacies specifically designed to identify abusers; and tamper-resistant prescription pads for controlled substances, which seems the most plausible and immediate solution to this problem.

    One of the most important factors that contribute to traffic accidents on the expressway is the low visibility, which may be caused by local or regional weather status such as agglomerate fog, rain, snow and sandstorm. A pre-warning system would be great help to prevent traffic accidents due to low visibility. Considering some problems of the existing system, such as the limited monitoring area and expensive cost, etc., a new kind of visibility pre-warning system is presented in this paper. The pre-warning system is made up of measuring nodes and communications bus. At the measuring node there is a long-distance photoelectric sensor, which is placed by means of cascade at the middle isolation strip along the expressway. Using the long-distance sensors makes it possible to monitor the visibility status of the whole expressway. CAN bus is used in this system as the communication bus to transmit information about visibility along the expressway. In virtue of the advantages of the CAN bus, a long distance network is constructed to meet the needs of the system, such as real time, reliability and low cost. With this new visibility pre-warning system, the visibility status of the whole expressway can be monitored in time and all day. In this paper, the architectural structure of the system is introduced, and also the detailed designs of the measuring node and hardware connection of the CAN bus communications is described.

    2007-12-01

    A prototype early warning system was developed in Romania in order to provide 25-35 seconds warning time for Bucharest facilities for earthquake with M >6.5. The prototype system consists of four components: network ground motion sensors in the epicentral area, an area centre in epicentre, a digital radio communication link and a central data centre. These components are fully functional at Romania seismic data centre (RO_NDC) in Bucharest since August 2003. The system is in testing phase for one important user from Bucharest the Van de Graff Accelerator were we provide about 25 seconds warning time before shaking occurs. Because the prototype system demonstrated that potentially useful warnings of strong shaking from Vrancea earthquakes are feasible, the National Institute for Earth Physics decide to implement this system for other four important facilities from Romania. At every user was installed a dedicate device which is able to stop trigger the specific safety rules for each facility. The system was tested only with offline earthquakes due to the fact that since August 2003 there was no strong earthquake such that the real time detection algorithm to issue an alarm. The detection algorithm is based on a combination of spectral and amplitude analysis for the first 4 seconds of the P wave.

    Recent advancements in technology (e.g., social networking, texting) have created new ways for dating youth to relate to one another, including in abusive ways via "cyber dating abuse." Cyber dating abuse is a form of teen dating violence that overlaps with other types of abuse (e.g., psychological) but also has several unique characteristics. Given the phenomenon's limited presence in dating violence literature, we focus on identifying how experiencing cyber dating abuse relates to youths' individual behaviors and experiences (e.g., substance use, sexual activity), psychosocial adjustment, school connection, family relationships, and partner relationships. A total of 3,745 youth (52% female, 74% White) in three northeastern states participated in the survey and reported currently being in a dating relationship or having been in one during the prior year. We found that experiences of cyber dating abuse were most significantly correlated with being female, committing a greater variety of delinquent behaviors, having had sexual activity in one's lifetime, having higher levels of depressive symptoms, and having higher levels of anger/hostility. Further, cyber dating abuse appeared somewhat more strongly related to depressive symptoms and delinquency than did other forms of teen dating violence and abuse.

  19. Application of Rapid Earthquake Location for Earthquake Early Warning in Korea

    NASA Astrophysics Data System (ADS)

    2008-12-01

    Economic growth, industrialization and urbanization have made society more vulnerable then ever to seismic hazard in Korea. Although Korea has not experienced severe damage due to earthquakes during the last few decades, there is little doubt of the potential for large earthquakes in Korea as documented in the historical literature. As we see no immediate promise of short-term earthquake prediction with current science and technology, earthquake early warning systems attract more and more attention as a practical measure to mitigate damage from earthquakes. Earthquake early warning systems provide a few seconds to tens of seconds of warning time before the onset of strong ground shaking. To achieve rapid earthquake location, we propose to take full advantage of information from existing seismic networks; by using P wave arrival times at two nearest stations from the earthquake hypocenter and also information that P waves have not yet arrived at other stations. Ten earthquakes in the Korean peninsula and its vicinity are selected for the feasibility study. We observed that location results are not reliable when earthquakes occur outside of the seismic network. Earthquakes inside the seismic network, however, can be located very rapidly for the purpose of earthquake early warning. Seoul metropolitan area may secure 10 - 50 seconds of warning time before any strong shaking starts for certain events. Carefully orchestrated actions during the given warning time should be able to reduce hazard and mitigate damages due to potentially disastrous earthquakes.

    The effects of earthquake shaking on the population and infrastructure across the State of Hawaii could be catastrophic, and the high seismic hazard in the region emphasizes the likelihood of such an event. Earthquake early warning (EEW) has the potential to give several seconds of warning before strong shaking starts, and thus reduce loss of life and damage to property. The two approaches to EEW are (1) a network approach (such as ShakeAlert or ElarmS) where the regional seismic network is used to detect the earthquake and distribute the alarm and (2) a local approach where a critical facility has a single seismometer (or small array) and a warning system on the premises.The network approach, also referred to here as ShakeAlert or ElarmS, uses the closest stations within a regional seismic network to detect and characterize an earthquake. Most parameters used for a network approach require observations on multiple stations (typically 3 or 4), which slows down the alarm time slightly, but the alarms are generally more reliable than with single-station EEW approaches. The network approach also benefits from having stations closer to the source of any potentially damaging earthquake, so that alarms can be sent ahead to anyone who subscribes to receive the notification. Thus, a fully implemented ShakeAlert system can provide seconds of warning for both critical facilities and general populations ahead of damaging earthquake shaking.The cost to implement and maintain a fully operational ShakeAlert system is high compared to a local approach or single-station solution, but the benefits of a ShakeAlert system would be felt statewide—the warning times for strong shaking are potentially longer for most sources at most locations.The local approach, referred to herein as “single station,” uses measurements from a single seismometer to assess whether strong earthquake shaking can be expected. Because of the reliance on a single station, false alarms are more common than

    Flash floods, which are typically triggered by severe rainfall events, are difficult to monitor and predict at the spatial and temporal scales of interest due to large meteorological and hydrologic uncertainties. In particular, uncertainties in quantitative precipitation forecasts (QPF) and quantitative precipitation estimates (QPE) need to be taken into account to provide skillful flash flood warnings with increased warning lead time. In France, the AIGA discharge-threshold flood warning system is currently being enhanced to ingest high-resolution ensemble QPFs from convection-permitting numerical weather prediction (NWP) models, as well as probabilistic QPEs, to improve flash flood warnings for small-to-medium (from 10 to 1000 km²) ungauged basins. The current deterministic AIGA system is operational in the South of France since 2005. It ingests the operational radar-gauge QPE grids from Météo-France to run a simplified hourly distributed hydrologic model at a 1-km² resolution every 15 minutes (Javelle et al. 2014). This produces real-time peak discharge estimates along the river network, which are subsequently compared to regionalized flood frequency estimates of given return periods. Warnings are then provided to the French national hydro-meteorological and flood forecasting centre (SCHAPI) and regional flood forecasting offices, based on the estimated severity of ongoing events. The calibration and regionalization of the hydrologic model has been recently enhanced to implement an operational flash flood warning system for the entire French territory. To quantify the QPF uncertainty, the COSMO-DE-EPS rainfall ensembles from the Deutscher Wetterdienst (20 members at a 2.8-km resolution for a lead time of 21 hours), which are available on the North-eastern part of France, were ingested in the hydrologic model of the AIGA system. Streamflow ensembles were produced and probabilistic flash flood warnings were derived for the Meuse and Moselle river basins and

    2012-04-01

    The integration of national Tsunami Early Earning Systems (TEWS) to ocean-wide networks is a main objective of the UNESCO Intergovernmental Oceanic Commission (IOC) tsunami programme. The intention is to interlink national TEWSs leveraging warning communication during hazards. For this purpose a communication model has been developed enabling an efficient message exchange within a centre-to-centre (C2C) communication in a system-of-systems environment. The model, designed to be robust and simple, is based on existing interoperability standards from the Open Geospatial Consortium (OGC) and the Organization of the Advancement of Structured Information Standards (OASIS). For the exchange of tsunami warning bulletins the Common Alerting Protocol (CAP) is used. It supports geospatial referencing by addressing geocoded Points of Interests (POIs), Areas of Interest (AOIs) and Coastal Forecast Zones (CFZs). Moreover it supports hazard classification by standardized criticality parameters and the transmission of attachments, e.g. situation maps. The communication model also supports the exchange of sensor observations and measurements such as sea level data or earthquake parameters. For this purpose markup languages of the Sensor Web Enablement (SWE) suite are used. Both communication products, warning bulletins and sensor observations, are embedded in an envelope providing addressing and routing information using the Emergency Data Exchange Language Distribution Element (EDXL-DE). The communication model has been implemented in a first pilot based on Message Oriented Middleware (MOM). Implementation, test and validation was started in the European research project Distant Early Warning System (DEWS) and is continued successively in the project Collaborative, Complex, and Critical Decision Processes in Evolving Crises (TRIDEC). Stimulated by the concepts and results of the German Indonesian Tsunami Early Warning System (GITEWS) and based on its sensor integration platform

    This paper has two objectives: first, to introduce the concept of multimodal action-specific warnings and its prototypic realization in the form of a warning glove and second, to present the main findings of a user study that was conducted to test the warning glove against a conventional warning system. Regarding the first goal, the combination of multimodality and action-specificity was implemented by attaching electronic actuators on a right-handed glove for transmitting visual, auditory and tactile feedback. For the second objective, a user study was conducted to test the hypothesis that the warning glove is capable of obtaining faster responses and to determine the perceptions of the users regarding the appropriateness of the warning glove. The results confirmed the assumption of faster response times and participants perceived the warning glove to be 'fairly appropriate'. These results warrant further development of this multimodal action-specific warning glove.

    Although lightning detection systems operated by government agencies, utilities and other businesses provide storm warnings, this information often does not reach the public until some time after the observations have been made. A low-cost personal lightning detector offers a significant safety advantage to private flyers, boaters, golfers and others. Developed by Airborne Research Associates, the detectors originated in Space Shuttle tests of an optical lightning detection technique. The commercial device is pointed toward a cloud to detect invisible intracloud lightning by sensing subtle changes in light presence. The majority of the sales have been to golf courses. Additional products and more advanced applications are in progress.

    Major advances have occurred over the last 20 years about how to effectively communicate risk information and warnings to the public. These lessons have been hard won. Knowledge has mounted on the finding from social scientific studies of risk communication failures, successes and those which fell somewhere in between. Moreover, the last 2 decades have borne witness to the brith, cultivation, and blossoming of information sharing between those physical scientists who discover new information about risk and those communcation scientists who trace its diffusion and then measure pbulic reaction.

    Many fire risk models have been developed for various temporal and spatial scales and application purposes. The integrated warning service in the Czech Republic is used for wildfire risk assessment model of FDI (Fire Danger Index). The FDI model is being developed in the Doksany observatory based on evaluation of weather conditions. FDI model describes danger of wildfire for vegetation covered countryside. There are five levels of danger: 1 - very low risk, 2 - low risk, 3 - moderate risk, 4 - high risk, 5 - very high risk. Simply say higher index value, reflects to higher risk of wildfire. As input data, the model uses measured values from the Czech Hydrometeorological Institute stations network as well as ALADIN's model predicted conditions. The modelling process computes upper soil profile moisture, surface moistening and the spreading speed of fire. Early warning system for wildfires prevention in the Czech Republic is used since 2006.

    A real-time system for issuing warnings of landslides during major storms is being developed for the San Francisco Bay region, California. The system is based on empirical and theoretical relations between rainfall and landslide initiation, geologic determination of areas susceptible to landslides, real-time monitoring of a regional network of telemetering rain gages, and National Weather Service precipitation forecasts. This system was used to issue warnings during the storms of 12 to 21 February 1986, which produced 800 millimeters of rainfall in the region. Although analysis after the storms suggests that modifications and additional developments are needed, the system successfully predicted the times of major landslide events. It could be used as a prototype for systems in other landslide-prone regions.

  16. GNSS Tsunami Warning System Augmentation for the Indo-Pacific Region

    NASA Astrophysics Data System (ADS)

    LaBrecque, J. L.

    2015-12-01

    The years since the devastating Banda Aceh Earthquake of December, 2004 have repeatedly inflicted the terrible loss of life and economic disruption from large earthquakes and resulting tsunamis upon Indo-Pacific coastal populations. The hardest hit populations are those closest to the earthquake source, a scenario for which most Indo-Pacific nations lack an adequate early warning system. Following the Banda Aceh Earthquake, GNSS based techniques were developed to provide accurate, timely, estimates of ground displacements, the modeling and monitoring of tsunami propagation. Major investments are also being made to deploy and upgrade existing GNSS constellations (GPS, GLONASS, Beidou, Galileo, GZSS, and IRNSS) by the end of this decade. There have also been significant investments in multi-GNSS ground networks and analysis centers that often provide measurements in real time. These multi-national investments now present the possibility for significant improvements to the Indo-Pacific region's tsunami warning. The development of GNSS based tsunami warning integrated with existing seismic based tsunami warning systems will provide a robust, accurate, timely, and cost effective network to provide effective warning for the Indo-Pacific coastal communities. The UN General Assembly has called for the sharing of geodetic data for the mitigation of natural hazards while the IUGG and IGS recommend the implementation of a GNSS based augmentation to the Tsunami Early Warning System. The same GNSS ground networks and constellations that support the Tsunami Early Warning network also provide Positioning, Navigation, and Timing and other benefits to these communities thereby insuring a sustainable and reliable capability.

    The implementation of the tsunami early warning systems in the NE Atlantic and Mediterranean regions will occur in countries with no preparedness and very little knowledge of potentially affected coastal zones by the various tsunami sources. The final link to coastal communities will be sirens to distribute in the concerned areas. The SCHEMA project aims at elaboration of a generic method to consider various parameters of a particular tsunami scenario. A scenario corresponds to a specific source with a given magnitude or intensity. Since we do not consider only the remote sources with possibilities of warning, local earthquake and submarine landslides are also translated in scenarios to allow the civil protections, municipalities and local stakeholders to assess cases with no real warning possibility, where life will be saved by self evacuation in nearby shelter areas or buildings. The specific temporal dimension of tsunami phenomenon is considered. Oceanic propagation time, expected duration of dangerous waves and wavelength are taken into account with their level of uncertainties. Scenarios are presented by maps and layouts with various information: inundation extension, submersion depth, receding sea limit, currents velocity or modulus of flow, modeled damage level to buildings, affected networks and lifelines. Variable dimensions such as residing or working population, by hour of the day and by season are also considered. Secondary vulnerability factors which may increase damage level to buildings are added (potentially floating objects which may turn into projectiles). The potential evacuation routes and obstacles are represented to support installation of warning networks and definition of shelters as well as evacuation routes. The scenarios are calculated using accurate digital bathymetric and topographic model with less than 10 m ground resolution allowing a very detailed mapping. This accuracy is especially important for scenarios with moderate waves for

  3. Human Response to Emergency Warning

    Almost every day people evacuate from their homes, businesses or other sites, even ships, in response to actual or predicted threats or hazards. Evacuation is the primary protective action utilized in large-scale emergencies such as hurricanes, floods, tornados, tsunamis, volcanic eruptions, or wildfires. Although often precautionary, protecting human lives by temporally relocating populations before or during times of threat remains a major emergency management strategy. One of the most formidable challenges facing emergency officials is evacuating residents for a fast-moving and largely unpredictable event such as a wildfire or a local tsunami. How to issue effective warnings to those at risk in time for residents to take appropriate action is an on-going problem. To do so, some communities have instituted advanced communications systems that include reverse telephone call-down systems or other alerting systems to notify at-risk residents of imminent threats. This presentation examines the effectiveness of using reverse telephone call-down systems for warning San Diego residents of wildfires in the October of 2007. This is the first systematic study conducted on this topic and is based on interviews with 1200 households in the evacuation areas.

    2013-12-01

    We present an operational plan for implementing combined seismic and geodetic time series in an earthquake early warning system for Cascadia. The Cascadian subduction zone presents one of the greatest risks for a megaquake in the continental United States. Ascertaining the full magnitude and extent of large earthquakes is problematic for earthquake early warning systems due to instability when double integrating strong-motion records to ground displacement. This problem can be mitigated by augmenting earthquake early warning systems with real-time GPS data, allowing for the progression and spatial extent of large earthquakes to be better resolved due to GPS's ability to measure both dynamic and permanent displacements. The Pacific Northwest Seismic Network (PNSN) at the University of Washington is implementing an integrated seismogeodetic approach to earthquake early warning. Regional GPS data are provided by the Pacific Northwest Geodetic Array (PANGA) at Central Washington University. Precise Point Positioning (PPP) solutions are sent from PANGA to the PNSN through JSON formatted streams and processed with a Python-based quality control (QC) module. The QC module also ingest accelerations from PNSN seismic stations through the Earthworm seismic acquisition and processing system for the purpose of detecting outliers and Kalman filtering when collocated instruments exist. The QC module outputs time aligned and cleaned displacement waveforms to ActiveMQ, an XML-based messaging broker that is currently used in seismic early warning architecture. Earthquake characterization modules read displacement information from ActiveMQ when triggered by warnings from ElarmS earthquake early warning algorithm. Peak ground displacement and P-wave scaling relationships from Kalman filtered waveforms provide initial magnitude estimates. Additional modules perform more complex source modeling such as centroid moment tensors and slip inversions that characterize the full size and

    2013-12-01

    The National Integrated Drought Information System (NIDIS) is in the process of developing drought early warning systems in areas of the U.S. where the coordination of drought information is critically needed. These regional drought early warning systems will become the backbone of a national drought early warning information system. Plans for the first drought early warning system started in the fall of 2008 in the Upper Colorado River Basin (UCRB), with an initial focus on the water supply in the head waters region of the Colorado River and the impacts of changes in the water supply on the UCRB. Since the establishment of the UCRB drought early warning system, other regional programs have begun in the Apalachicola-Chattahoochee-Flint River Basin, four regions in the state of California, the Southern Plains, and the Four Corners region. (At this time these are considered pilot drought early warning programs, not full-fledged drought early warning systems such as the UCRB.) Activities in each of these regions are tailored to the needs of stakeholders, and all incorporate hydrometeorological predictions. However, in all of these areas NIDIS has not focused on the specific needs of coastal ecosystems during times of drought. Over the past year, NIDIS has started a pilot drought early warning system that addresses drought in the coastal ecosystems of North and South Carolina. This pilot is being developed in partnership with the Carolinas Integrated Sciences and Assessments (CISA), a NOAA Regional Sciences and Assessments program housed at the University of South Carolina. Currently the focus of the Carolinas pilot includes the promotion of enhanced drought impact reporting to better understand the impacts of low flows on coastal ecosystems and the development of a USGS real-time salinity network for a few coastal gage stations in the Carolinas. The roles of the enhanced drought impact assessments in coastal ecosystems and the knowledge gained from a real

  14. Urban Flood Warning Systems using Radar Technologies

    NASA Astrophysics Data System (ADS)

    Fang, N.; Bedient, P. B.

    2013-12-01

    There have been an increasing number of urban areas that rely on weather radars to provide accurate precipitation information for flood warning purposes. As non-structural tools, radar-based flood warning systems can provide accurate and timely warnings to the public and private entities in urban areas that are prone to flash floods. The wider spatial and temporal coverage from radar increases flood warning lead-time when compared to rain and stream gages alone. The Third Generation Rice and Texas Medical Center (TMC) Flood Alert System (FAS3) has been delivering warning information with 2 to 3 hours of lead time and a R2 value of 93% to facility personnel in a readily understood format for more than 50 events in the past 15 years. The current FAS utilizes NEXRAD Level II radar rainfall data coupled with a real-time hydrologic model (RTHEC-1) to deliver warning information. The system has a user-friendly dashboard to provide rainfall maps, Google Maps based inundation maps, hydrologic predictions, and real-time monitoring at the bayou. This paper will evaluate its reliable performance during the recent events occurring in 2012 and 2013 and the development of a similar radar-based flood warning system for the City of Sugar Land, Texas. Having a significant role in the communication of flood information, FAS marks an important step towards the establishment of an operational and reliable flood warning system for flood-prone urban areas.

    Inhalant abuse is the intentional inhalation of a volatile substance for the purpose of achieving an altered mental state. As an important, yet underrecognized form of substance abuse, inhalant abuse crosses all demographic, ethnic, and socioeconomic boundaries, causing significant morbidity and mortality in school-aged and older children. This review presents current perspectives on epidemiology, detection, and clinical challenges of inhalant abuse and offers advice regarding the medical and mental health providers' roles in the prevention and management of this substance abuse problem. Also discussed is the misuse of a specific "over-the-counter" dissociative, dextromethorphan. PMID:27338970

    EWS for Vrancea earthquakes uses the time interval (28-32 sec.) between the moment when the earthquake is detected by the local seismic network installed in the epicenter area (Vrancea) and the arrival time of the seismic waves in the protected area (Bucharest) to send earthquake warning to users. In the last years, National Institute for Earth Physics (NIEP) upgraded its seismic network in order to cover better the seismic zones of Romania. Currently the National Institute for Earth Physics (NIEP) operates a real-time seismic network designed to monitor the seismic activity on the Romania territory, dominated by the Vrancea intermediate-depth (60-200 km) earthquakes. The NIEP real-time network consists of 102 stations and two seismic arrays equipped with different high quality digitizers (Kinemetrics K2, Quanterra Q330, Quanterra Q330HR, PS6-26, Basalt), broadband and short period seismometers (CMG3ESP, CMG40T, KS2000, KS54000, KS2000, CMG3T,STS2, SH-1, S13, Ranger, gs21, Mark l22) and acceleration sensors (Episensor). Recent improvement of the seismic network and real-time communication technologies allows implementation of a nation-wide EEWS for Vrancea and other seismic sources from Romania. We present a regional approach to Earthquake Early Warning for Romania earthquakes. The regional approach is based on PRESTo (Probabilistic and Evolutionary early warning SysTem) software platform: PRESTo processes in real-time three channel acceleration data streams: once the P-waves arrival have been detected, it provides earthquake location and magnitude estimations, and peak ground motion predictions at target sites. PRESTo is currently implemented in real- time at National Institute for Earth Physics, Bucharest for several months in parallel with a secondary EEWS. The alert notification is issued only when both systems validate each other. Here we present the results obtained using offline earthquakes originating from Vrancea area together with several real

    Medical marijuana is legal in some countries, including in many US states. At present, there are no government-mandated warnings on packages of marijuana, even though the substance has dangers similar to those of alcohol, tobacco, and various prescribed drugs. This article reports the results of an effort to collect marijuana warnings recommended by scientific experts on marijuana. The recommended warnings, the first ever from marijuana experts, come from 13 experts. The expert-recommended warnings pertain to risks relating to (1) safety, (2) physical health, (3) fetal harm, (4) mental health, (5) withdrawal and dependence, and (6) adolescent development. The results provide initial expert recommendations for warnings to be required on packages of medical marijuana.

    The low cost MEMS accelerometers in the smartphones are attracting more and more attentions from the science community due to the vast number and potential applications in various areas. We are using the accelerometers inside the smartphones to detect the earthquakes. We did shake table tests to show these accelerometers are also suitable to record large shakings caused by earthquakes. We developed an android app - MyShake, which can even distinguish earthquake movements from daily human activities from the recordings recorded by the accelerometers in personal smartphones and upload trigger information/waveform to our server for further analysis. The data from these smartphones forms a unique datasets for seismological applications, such as earthquake early warning. In this talk I will layout the method we used to recognize earthquake-like movement from single smartphone, and the overview of the whole system that harness the information from a network of smartphones for rapid earthquake detection. This type of system can be easily deployed and scaled up around the global and provides additional insights of the earthquake hazards.

  9. An interagency working group on lightning threat warning

    SciTech Connect

    Hasbrouck, R.T.

    1988-01-01

    In a lightning environment, it is desirable to experience a thunderstorm without sustaining serious physical or economic loss. Properly implemented and maintained protection techniques go a long way toward minimizing or eliminating losses. However, activities that cannot be pracitcally protected must be temporarily curtailed during a lightning hazard period. Thus, some method for sensing the onset and departure of the hazard is required. Untimely curtailment or resumption of activities can place personnel and equipment in jeopardy, or result in excessive, and expensive, downtime. False alarms are equally undesirable. Presently, this need for a lightning warning system can be partially met through the use of a cloud-to-ground lightning detection and tracking system. Several manufacturers are installing these systems and the Federal government is seeking to coordinate them into a nationwide network. However, these systems do not provide lightning threat (pre-first-strike) warning. Techniques and equipment for producting such warnings exist, but until recently there has been no unified effort to consolidate the knowledge, standardize the requirements, and identify the problems of the various users. This paper will briefly describe the formation of an interagency working group which intends to specifically address such issues. 4 refs.

  10. Feasibility study of earthquake early warning (EEW) in Hawaii

    USGS Publications Warehouse

    Thelen, Weston A.; Hotovec-Ellis, Alicia J.; Bodin, Paul

    2016-09-30

    The effects of earthquake shaking on the population and infrastructure across the State of Hawaii could be catastrophic, and the high seismic hazard in the region emphasizes the likelihood of such an event. Earthquake early warning (EEW) has the potential to give several seconds of warning before strong shaking starts, and thus reduce loss of life and damage to property. The two approaches to EEW are (1) a network approach (such as ShakeAlert or ElarmS) where the regional seismic network is used to detect the earthquake and distribute the alarm and (2) a local approach where a critical facility has a single seismometer (or small array) and a warning system on the premises.The network approach, also referred to here as ShakeAlert or ElarmS, uses the closest stations within a regional seismic network to detect and characterize an earthquake. Most parameters used for a network approach require observations on multiple stations (typically 3 or 4), which slows down the alarm time slightly, but the alarms are generally more reliable than with single-station EEW approaches. The network approach also benefits from having stations closer to the source of any potentially damaging earthquake, so that alarms can be sent ahead to anyone who subscribes to receive the notification. Thus, a fully implemented ShakeAlert system can provide seconds of warning for both critical facilities and general populations ahead of damaging earthquake shaking.The cost to implement and maintain a fully operational ShakeAlert system is high compared to a local approach or single-station solution, but the benefits of a ShakeAlert system would be felt statewide—the warning times for strong shaking are potentially longer for most sources at most locations.The local approach, referred to herein as “single station,” uses measurements from a single seismometer to assess whether strong earthquake shaking can be expected. Because of the reliance on a single station, false alarms are more common than

    The management of natural crises is an important application field of the technology developed in the project Collaborative, Complex, and Critical Decision-Support in Evolving Crises (TRIDEC), co-funded by the European Commission in its Seventh Framework Programme. TRIDEC is based on the development of the German Indonesian Tsunami Early Warning System (GITEWS) and the Distant Early Warning System (DEWS) providing a service platform for both sensor integration and warning dissemination. In TRIDEC new developments in Information and Communication Technology (ICT) are used to extend the existing platform realising a component-based technology framework for building distributed tsunami warning systems for deployment, e.g. in the North-eastern Atlantic, the Mediterranean and Connected Seas (NEAM) region. The TRIDEC system will be implemented in three phases, each with a demonstrator. Successively, the demonstrators are addressing challenges, such as the design and implementation of a robust and scalable service infrastructure supporting the integration and utilisation of existing resources with accelerated generation of large volumes of data. These include sensor systems, geo-information repositories, simulation tools and data fusion tools. In addition to conventional sensors also unconventional sensors and sensor networks play an important role in TRIDEC. The system version presented is based on service-oriented architecture (SOA) concepts and on relevant standards of the Open Geospatial Consortium (OGC), the World Wide Web Consortium (W3C) and the Organization for the Advancement of Structured Information Standards (OASIS). In this way the system continuously gathers, processes and displays events and data coming from open sensor platforms to enable operators to quickly decide whether an early warning is necessary and to send personalized warning messages to the authorities and the population at large through a wide range of communication channels.

    The Cascadia subduction zone poses one of the greatest risks for a megaquake in the continental United States and, because of this, the Pacific Northwest Seismic Network (PNSN) at the University of Washington is building a joint seismic and geodetic earthquake early warning system. Our two-stage approach to earthquake early warning includes: (1) detection and initial characterization using strong-motion and broadband data from the PNSN with the ElarmS package, and (2) geodetic modeling modules using GPS data from the Pacific Northwest Geodetic Array (PANGA) and combined seismogeodetic (GPS + strong-motion) data. Because of Cascadia's relatively low seismicity rate and the paucity of data from plate boundary earthquakes, we have prioritized the development of a test system and the creation of several large simulated events. The test system permits us to: (1) replay segments of actual seismic waveform data recorded from the PNSN and neighboring networks to represent both earthquakes and noise conditions, and (2) broadcast synthetic data into the system to simulate signals we anticipate from earthquakes for which we have no actual ground motion recordings. The test system lets us also simulate various error conditions (latent and/or out-of-sequence data, telemetry drop-outs, etc.) and to explore how best to mitigate them. Here, we report on the performance of the joint early warning system and the geodetic modeling modules in a simulated real-time mode using simulated 5-Hz displacements from plausible Cascadian earthquake scenarios. The simulations are created using the FK integration method for hypothetical source models for a wide array of possible faulting types and magnitudes. The results show that the geodetic modeling modules are able to properly characterize the simulated events, and we discuss the limitations with respect to latency, network architecture, and earthquake location throughout the Pacific Northwest.

  14. An early warning system for overcrowding in the emergency department.

    2006-01-01

    Overcrowding of emergency departments impedes health care access and quality nationwide. A real-time early warning system for overcrowding may allow administrators to alleviate the problem before reaching a crisis state. Two original probabilistic models - a logistic regression and a recurrent neural network - were created to predict overcrowding crises one hour in the future. The two original and two pre-existing models were validated at 8,496 observation points from January 1, 2006 to February 28, 2006. All models showed high discriminatory ability in terms of area under the receiver operating characteristic curve (logistic regression = .954; recurrent neural network = .957; EDWIN = .879; NEDOCS = .924). At comparable rates of false alarms, the logistic regression gave more advance notice of crises than other models (logistic regression = 62 min; recurrent neural network = 13 min; EDWIN = 0 min; NEDOCS = 0 min). These results demonstrate the feasibility of using models based on key operational variables to anticipate overcrowding crises in real time. PMID:17238359

    The Government of Israel has resolved on June 7, 2012 to build a nationwide Earthquake Early Warning System (EEWS). Towards this goal, the Israeli Earth and Marine Research Administration (EMRA) assembled an advisory committee, composed of international EEW experts and Israeli scientists. The proposed system is planned to provide earthquake warning to schools around the nation within 2 years of project commencement, and nationwide warning beyond a period of 3 years. The Israeli EEWS will be constructed as a seismic fence along the major fault systems, and will be integrated into the regional Israeli Seismic Network (ISN). The seismic equipment at the entire integrated network will be of similar standards. The recommended alarm approach for Israel will be hybrid: an S-wave based threshold alert will be merged with a P-wave based algorithm. The S-wave based threshold algorithm will alert when two or more seismic stations observe ground shaking above a pre-defined strong shaking level. The P-wave based algorithm uses waves which travel about twice as fast as S-waves to detect earthquakes, characterize the source magnitude and location, and then issue an alert based on predicted shaking. This approach allows for location specific alerts and regular testing through detection of smaller earthquakes, and will be useful for events occurring far from the known major faults. The proposed new seismic network to be installed is as follows: A total number of about 50 accelerometer-only sites will be deployed close to the Dead Sea and Carmel Faults in a single line of stations every ~10 km, south of the Dead Sea, and in a staggered geometry from the Dead Sea northward. Five additional sites with co-located seismometers and accelerometers should be deployed at large spacing along the Dead Sea Fault. The feasibility of the system is confirmed by travel-time calculations. The new seismic network will provide a significant amount of geophysical data that should be effectively mined

  16. Quantifying the effect of early warning systems for mitigating risks from alpine hazards

    Early warning systems (EWS) are increasingly applied as flexible and non-intrusive measures for mitigating risks from alpine hazards. They are typically planed and installed in an ad-hoc manner and their effectiveness is not quantified, which is in contrast to structural risk mitigation measures. The effect of an EWS on the risk depends on human decision makers: experts interpret the signals from EWS, authorities decide on intervention measures and the public responds to the warnings. This interaction of the EWS with humans makes the quantification of their effectiveness challenging. Nevertheless, such a quantification is an important step in understanding, improving and justifying the use of EWS. We systematically discuss and demonstrate the factors that influence EWS effectiveness for alpine hazards, and present approaches and tools for analysing them. These include Bayesian network models, which are a powerful tool for an integral probabilistic assessment. The theory is illustrated through applications of warning systems for debris flow and rockfall hazards. References: Sättele M., Bründl M., Straub D. (in print).

    Geohazards, such as tsunamis, inflict an enormous cost on society and mitigation of disasters through early warnings will save lives and reduce economic losses. Tsunami warning is a race against time on local, regional and distant scales. Tsunami warning systems include several components. Today sensor networks generally consist of seismic sensors and coastal tide gauges to validate the tsunami wave characteristics and inundation. In addition several new signal networks are being incorporated such as ocean buoys, deep ocean pressure recorders and GNSS. Current operational weaknesses of tsunami warning centers include an inability to detect landslides and volcanic sources, and an inability to provide early-enough warnings for local tsunamis except in a few cases. Europe is prone to local tsunamis and hence rapid estimates of the geophysical parameters will be pivotal for the NEAMTWS, the regional component of UNESCO's ITWS. The challenge is to provide high quality information at the right time. In the case of local tsunamis that means within less than 5 minutes. GNSS describes displacements of the Earth's crust and may improve the rapid determination of the magnitude and fault geometry of an earthquake. Particularly for large earthquakes, GNSS can radically reduce the response time and accuracy of tsunami warnings. GNSS contributes to the knowledge about sources of tsunamis pre-, co- and post event which are important input for the warning system. GNSS can also contribute to tsunami warning systems for non-seismic events such caused by landslides, precarious rocks and volcanoes. A description of GNSS products and methods that can be applied in those cases are discussed. We present an overview and discuss GNSS's existing and potential contributions to tsunami warning systems, including non-seismic sources. For tsunamis caused by earthquakes, real-time GNSS analysis strategies are assessed. An evaluation with suggestions for improvements of the existing geodetic

    An intriguing hypothesis is that clinical supervision may protect against counselor turnover. This idea has been mentioned in recent discussions of the substance abuse treatment workforce. To test this hypothesis, we extend our previous research on emotional exhaustion and turnover intention among counselors by estimating the associations between clinical supervision and these variables in a large sample (n = 823). An exploratory analysis reveals that clinical supervision was negatively associated with emotional exhaustion and turnover intention. Given our previous findings that emotional exhaustion and turnover intention were associated with job autonomy, procedural justice, and distributive justice, we estimate a structural equation model to examine whether these variables mediated clinical supervision’s associations with emotional exhaustion and turnover intention. These data support the fully mediated model. We found the perceived quality of clinical supervision is strongly associated with counselors’ perceptions of job autonomy, procedural justice, and distributive justice, which are, in turn, associated with emotional exhaustion and turnover intention. These data offer support for the protective role of clinical supervision in substance abuse treatment counselors’ turnover and occupational wellbeing. PMID:18424048

    Previous studies have shown that saccadic eye responses but not manual responses were sensitive to the kind of warning signal used, with visual onsets producing longer saccadic latencies compared to visual offsets. The aim of the present study was to determine the effects of distinct warning signals on manual latencies and to test the premise that the onset interference, in fact, does not occur for manual responses. A second objective was to determine if the magnitude of the warning effects could be modulated by contextual procedures. Three experimental conditions based on the kind of warning signal used (visual onset, visual offset and auditory warning) were run in two different contexts (blocked and non-blocked). Eighteen participants were asked to respond to the imperative stimulus that would occur some milliseconds (0, 250, 500 or 750 ms) after the warning signal. The experiment consisted in three experimental sessions of 240 trials, where all the variables were counterbalanced. The data showed that visual onsets produced longer manual latencies than visual offsets in the non-blocked context (275 vs 261 ms; P < 0.001). This interference was obtained, however, only for short intervals between the warning and the stimulus, and was abolished when the blocked context was used (256 vs 255 ms; P = 0.789). These results are discussed in terms of bottom-up and top-down interactions, mainly those related to the role of attentional processing in cancelling out competitive interactions and suppressive influences of a distractor on the relevant stimulus.

    In recent years, with the increasing world environmental pollution happening, sudden water pollution incident has become more and more frequently in China. It has posed a serious threat to water safety of the people living in the water source area. Conventional water pollution monitoring method is manual periodic testing, it maybe miss the best time to find that pollution incident. This paper proposes a water pollution warning framework to change this state. On the basis of the Internet of things, we uses automatic water quality monitoring technology to realize monitoring. We calculate the monitoring data with water pollution model to judge whether the water pollution incident is happen or not. Water pollution warning framework is divided into three layers: terminal as the sensing layer, it with the deployment of the automatic water quality pollution monitoring sensor. The middle layer is the transfer network layer, data information implementation is based on GPRS wireless network transmission. The upper one is the application layer. With these application systems, early warning information of water pollution will realize the high-speed transmission between grassroots units and superior units. The paper finally gives an example that applying this pollution warning framework to water quality monitoring of Beijing, China, it greatly improves the speed of the pollution warning responding of Beijing.

    Exemplifying the tsunami source immediately after an earthquake is the most critical component of tsunami early warning, as not every earthquake generates a tsunami. After a major under sea earthquake, it is very important to determine whether or not it has actually triggered the deadly wave. The near real-time observations from near field networks such as strong motion and Global Positioning System (GPS) allows rapid determination of fault geometry. Here we present a complete processing chain of Indian Tsunami Early Warning System (ITEWS), starting from acquisition of geodetic raw data, processing, inversion and simulating the situation as it would be at warning center during any major earthquake. We determine the earthquake moment magnitude and generate the centroid moment tensor solution using a novel approach which are the key elements for tsunami early warning. Though the well established seismic monitoring network, numerical modeling and dissemination system are currently capable to provide tsunami warnings to most of the countries in and around the Indian Ocean, the study highlights the critical role of geodetic observations in determination of tsunami source for high-quality forecasting.

    2014-02-01

    The incidence of drug abuse with alternative agents is increasing. The term "alternative drugs of abuse" is a catch-all term for abused chemicals that do not fit into one of the classic categories of drugs of abuse. The most common age group abusing these agents range from 17 to 25 years old and are often associated with group settings. Due to their diverse pharmacological nature, legislative efforts to classify these chemicals as a schedule I drug have lagged behind the development of new alternative agents. The potential reason for abuse of these agents is their hallucinogenic, dissociative, stimulant, anti-muscarinic, or sedative properties. Some of these drugs are easily obtainable such as Datura stramonium (Jimson Weed) or Lophophora williamsii (Peyote) because they are natural plants indigenous to certain regions. The diverse pharmacology and clinical effects of these agents are so broad that they do not produce a universal constellation of signs and symptoms. Detailed physical exams are essential for identifying clues leading one to suspect an alternative drug of abuse. Testing for the presence of these agents is often limited, and even when available, the results do not return in a timely fashion. Intoxications from these agents pose unique challenges for health care providers. Physician knowledge of the physiological effects of these alternative agents and the local patterns of drug of abuse are important for the accurate diagnosis and optimal care of poisoned patients. This review summarizes the current knowledge of alternative drugs of abuse and highlights their clinical presentations. PMID:23636733

    2013-12-01

    In 2010, the U.S. National Weather Service (NWS) funded a three year project to integrate social science into their Tsunami Program. One of three primary requirements of the grant was to make improvements to tsunami warning messages of the NWS' two Tsunami Warning Centers- the West Coast/Alaska Tsunami Warning Center (WCATWC) in Palmer, Alaska and the Pacific Tsunami Warning Center (PTWC) in Ewa Beach, Hawaii. We conducted focus group meetings with a purposive sample of local, state and Federal stakeholders and emergency managers in six states (AK, WA, OR, CA, HI and NC) and two US Territories (US Virgin Islands and American Samoa) to qualitatively asses information needs in tsunami warning messages using WCATWC tsunami messages for the March 2011 Tohoku earthquake and tsunami event. We also reviewed research literature on behavioral response to warnings to develop a tsunami warning message metric that could be used to guide revisions to tsunami warning messages of both warning centers. The message metric is divided into categories of Message Content, Style, Order and Formatting and Receiver Characteristics. A message is evaluated by cross-referencing the message with the operational definitions of metric factors. Findings are then used to guide revisions of the message until the characteristics of each factor are met. Using findings from this project and findings from a parallel NWS Warning Tiger Team study led by T. Nicolini, the WCATWC implemented the first of two phases of revisions to their warning messages in November 2012. A second phase of additional changes, which will fully implement the redesign of messages based on the metric, is in progress. The resulting messages will reflect current state-of-the-art knowledge on warning message effectiveness. Here we present the message metric; evidence-based rational for message factors; and examples of previous, existing and proposed messages.

    With the constant expansion of the scale and mismanagement in aquaculture,the diseases of flounder occur more and more frequently than before, which has brought great economic losses to fish farmers. For the sake of the problem described above, based on a great number of surveys, the early warning theory of flounder disease, the analysis of the outbreak and development of diseases and the relationship between disease and factors, the logic process of the early warning for flounder disease was confirmed. It consists of five parts: specifying the target, searching for the source, distinguishing the sign, predicting the degree and eliminating the menace. Using the expert survey method the early warning indexes which affect the normal life of the flounder and calculated the range of the water environment factors were also confirmed. Finally, an early warning system was implemented, which can reduce the damage from the flounder disease.

    Abuse of sildenafil has been reported since its introduction in 1999 and commonly documented in combination with illicit drugs among men and women of all ages. Increased risks of sexually transmissible diseases including HIV have been associated with sildenafil use in men who have sex with men. Recognizing the abuse potential of phosphodiesterase type 5 inhibitors (PDE5), we aim to summarize the current knowledge of this abuse. An investigation of EMBASE, PubMed, the Food and Drug Administration (FDA) website, MedWatch, and search engines was performed to evaluate information regarding sildenafil, tadalafil, and vardenafil abuse. The EMBASE search provided 46 articles fitting the search criteria and evaluation led to 21 separate publications with specific information regarding PDE5 abuse. A PubMed search found 10 additional publications. MedWatch reported 44 separate warnings since 2000, most of which reported contamination of herbal products with active drug components. Few reports of abuse were among the 14,818 reports in the FDA AERS for sildenafil. A search for "internet drug store" revealed 6.4 million hits and of 7000 internet pharmacies identified by the Verified Internet Pharmacy Practice Sites Program (VIPPS) only 4% were in proper compliance. The role internet pharmacies play in counterfeit PDE5 or abuse is not well documented; however based on easy access, direct patient marketing, and low advertised cost it is likely this role is underreported. Currently the best recommendation for providers is to recognize the possibility of abuse and to educate patients on risks of this behavior. PMID:21696344

    2000-12-01

    This study examines the effectiveness of social support networks on psychological well-being among 602 homeless and runaway adolescents. The respondents were interviewed in shelters, drop-in centers, and on the streets in cities of four Midwestern states (Missouri, Iowa, Nebraska, and Kansas). The path model was used to test the direct effect of family abuse and precocious independence on adolescent depressive symptoms and indirect effects through social support networks. Results indicate that although abusive family origins contribute directly to depressive symptoms there are indirect effects of family abuse and early independence through social support networks. Family abuse and early independence drive homeless adolescents to rely on peers for social support. While support from friends on the street reduces depression, association with deviant peers increases depression.

  3. Novelty effects in a multimodal warning signal.

    PubMed

    Rowe; Guilford

    1999-02-01

    The warning signals of toxic insects are often 'multimodal', combining bright coloration with sounds or odours (or both). Pyrazine (a common insect warning odour) can elicit an intrinsic avoidance in domestic chicks Gallus gallus domesticus, both against novel coloured food, and also against food colours that are specifically associated with aposematism, namely yellow and red. In three experiments, we investigated the role of novelty in this innate bias against yellow coloured food in the presence of pyrazine. Naive chicks were familiarized either to pyrazine odour or to coloured food before being tested for a bias against yellow (warningly coloured) food as opposed to green (nonwarningly coloured) food. In experiment 1, pyrazine novelty was shown to be vital for eliciting a bias against yellow food. However, experiment 2 suggested that colour novelty was not important: chicks familiarized with coloured crumbs still avoided yellow crumbs when pyrazine was presented. In a third experiment that gave chicks an even greater degree of pre-exposure to coloured crumbs, the bias against yellow food eventually waned, although pyrazine continued to elicit an aversion to yellow even after birds had had experience of up to 24 palatable yellow crumbs. Pyrazine novelty has been an important pressure in the evolution of multimodal warning signals, and can continue to promote the avoidance of warningly coloured food, even when it is relatively familiar. The implications for warning signals are discussed. Copyright 1999 The Association for the Study of Animal Behaviour.

    Each year, about 60 000 people and $4 billion (US$) in assets are exposed to the global tsunami hazard. Accurate and reliable tsunami warning systems have been shown to provide a significant defence for this flooding hazard. However, the evolution of warning systems has been influenced by two processes: deadly tsunamis and available technology. In this paper, we explore the evolution of science and technology used in tsunami warning systems, the evolution of their products using warning technologies, and offer suggestions for a new generation of warning products, aimed at the flooding nature of the hazard, to reduce future tsunami impacts on society. We conclude that coastal communities would be well served by receiving three standardized, accurate, real-time tsunami warning products, namely (i) tsunami energy estimate, (ii) flooding maps and (iii) tsunami-induced harbour current maps to minimize the impact of tsunamis. Such information would arm communities with vital flooding guidance for evacuations and port operations. The advantage of global standardized flooding products delivered in a common format is efficiency and accuracy, which leads to effectiveness in promoting tsunami resilience at the community level.

    OBJECTIVES: To determine the prevalence of physical abuse during late pregnancy and to investigate how abused and nonabused pregnant women differ in demographic characteristics, health habits, psychologic distress and attitudes about fetal health. DESIGN: Survey of women attending for prenatal health care or admitted to hospital for delivery. The information was obtained on one occasion from self-report questionnaires, completed with the option of anonymity. SETTINGS: Community-based prenatal clinic, private obstetricians' offices in a large city, private family physicians' offices in a large city, family physicians' offices in a small town, and a university teaching hospital. PATIENTS: English-speaking women at 20 weeks' or more gestation attending or admitted consecutively. INTERVENTIONS: Three self-report questionnaires: the General Health Questionnaire (GHQ), the Fetal Health Locus of Control (FHLC) and the study questionnaire. RESULTS: Thirteen women (2.4%) refused to participate in the survey. Of the 548 women who completed the questionnaires 36 (6.6%) reported physical abuse during the current pregnancy and 60 (10.9%) before it. There were no significant differences in rates of abuse between settings. Of the women abused during the pregnancy 23 (63.9%) reported increased abuse during the pregnancy, and 28 (77.8%) remained with the abuser. Twenty-four pregnant women (66.7%) received medical treatment for abuse, but only 1 (2.8%) told her prenatal care provider of the abuse. Factor analysis revealed three factors associated with physical abuse in pregnancy: "social instability" (comprising low age, unmarried status, lower level of education, unemployment and unplanned pregnancy), "unhealthy lifestyle" (comprising poor diet, alcohol use, illicit drug use and emotional problems) and "physical health problems" (comprising health problems and prescription drug use). The GHQ scores showed that the abused women were significantly more emotionally distressed than the

  15. The integrated local flood warning system: A look at the flood response system

    1988-01-01

    Local Flood Warning Systems are instituted and maintained at a local level. They consist of two parts: (1) the flood forecast system, and (2) the flood response system. The flood forecast system is primarily built around the technology used to predict flooding. In this paper, we stress two points about local flood warning systems. First, the system must be integrated. Specifically, collecting data, transmitting data, forecasting the flood, informing local officials, warning local residents, and taking protective action (including evacuation of residents) must all occur in an integrated fashion if the whole system is to succeed. Second, we outline some important organizational characteristics that should be improved when developing a local flood response system. Key organizational characteristics include experience, networks, communications, decision making, everyday disaster task overlap. By focusing upon experience (including learning from the past flood or disaster experience or participating in drills and exercises) and by improving preparedness can be inexpensively improved. 6 refs.,

    Network analysis and GIS enable the presentation of meaningful data about organizational relationships and community characteristics, respectively. Together, these tools can provide a concrete representation of the ecological context in which coalitions operate, and may help coalitions identify opportunities for growth and enhanced effectiveness. This study uses network analysis and GIS mapping as part of an evaluation of the One Strong 'Ohana (OSO) campaign. The OSO campaign was launched in 2012 via a partnership between the Hawai'i Children's Trust Fund (HCTF) and the Joyful Heart Foundation. The OSO campaign uses a collaborative approach aimed at increasing public awareness of child maltreatment and protective factors that can prevent maltreatment, as well as enhancing the effectiveness of the HCTF Coalition. This study focuses on three elements of the OSO campaign evaluation: (1) Network analysis exploring the relationships between 24 active Coalition member organizations, (2) GIS mapping of responses to a randomized statewide phone survey (n = 1,450) assessing awareness of factors contributing to child maltreatment, and (3) Combined GIS maps and network data, illustrating opportunities for geographically-targeted coalition building and public awareness activities.

  18. Aspects of abuse: abusive head trauma.

    PubMed

    Hinds, Tanya; Shalaby-Rana, Eglal; Jackson, Allison M; Khademian, Zarir

    2015-03-01

    Abusive Head Trauma (AHT) is a form of child physical abuse that involves inflicted injury to the brain and its associated structures. Abusive Head Trauma, colloquially called Shaken Baby Syndrome, is the most common cause of serious or fatal brain injuries in children aged 2 years and younger. The American Academy of Pediatrics recommends the term Abusive Head Trauma, as opposed to Shaken Baby Syndrome, as the former term encompasses multiple forms of inflicted head injury (inertial, contact, and hypoxic-ischemic) and a range of clinical presentations and radiologic findings and their sequelae. Children diagnosed with AHT are 5 times more likely to die compared with accidentally head-injured children, yet signs and symptoms are not always obvious, and therefore the diagnosis can be overlooked. Therefore, the American Academy of Pediatrics has tasked pediatricians with knowing how and when to begin an evaluation of children with signs and symptoms that could possibly be due to AHT. Overall, a detailed history of present illness and medical history, recognition of physical and radiological findings, and careful interpretation of retinal pathology are important aspects of formulating the differential diagnoses and increasing or decreasing the index of suspicion for AHT.

    Context In England around 5 million homes are at risk of flooding. We invest significantly in flood prevention and management schemes but we can never prevent all flooding. Early alerting systems are fundamental to helping us reduce the impacts of flooding. The Environment Agency has had the responsibility for flood warning since 1996. In 2006 we invested in a new dissemination system that would send direct messages to pre-identified recipients via a range of channels. Since then we have continuously improved the system and service we offer. In 2010 we introduced an 'opt-out' service where we pre-registered landline numbers in flood risk areas, significantly increasing the customer base. The service has performed exceptionally well under intense flood conditions. Over a period of 3 days in December 2013, when England was experiencing an east coast storm surge, the system sent nearly 350,000 telephone messages, 85,000 emails and 70,000 text messages, with a peak call rate of around 37,000 per hour and 100% availability. The Floodline Warnings Direct (FWD) System FWD provides warnings in advance of flooding so that people at risk and responders can take action to minimise the impact of the flood. Warnings are sent via telephone, fax, text message, pager or e-mail to over 1.1 million properties located within flood risk areas in England. Triggers for issuing alerts and warnings include attained and forecast river levels and rainfall in some rapidly responding locations. There are three levels of warning: Flood Alert, Flood Warning and Severe Flood Warning, and a stand down message. The warnings can be updated to include relevant information to help inform those at risk. Working with our current provider Fujitsu, the system is under a programme of continuous improvement including expanding the 'opt-out' service to mobile phone numbers registered to at risk addresses, allowing mobile registration to the system for people 'on the move' and providing access to

  20. Elder Abuse and Help-Seeking Behavior in Elderly Chinese.

    PubMed

    Yan, Elsie

    2015-09-01

    Elder abuse is a prevalent phenomenon resulting in physical, emotional, and social costs to individuals, families, and society. Timely and effective intervention is crucial because victims are often involved in relationships where re-victimization is common. Most elder abuse victims, however, are reluctant to seek help from outside their families. The aim of the present study is to explore factors associated with help-seeking behaviors among mistreated elders in Hong Kong. In-depth interviews were conducted with 40 elder abuse survivors. Although almost all of the participants could provide some examples of elder abuse, most denied that their own experience was abusive. Personal and professional social networks were important determinants of help seeking. Social isolation, cultural barriers, self-blame, and lack of knowledge were major barriers to help seeking.

  1. Implementing the national AIGA flash flood warning system in France

    The French national hydro-meteorological and flood forecasting centre (SCHAPI) aims to implement a national flash flood warning system to improve flood alerts for small-to-medium (up to 1000 km2) ungauged basins. This system is based on the AIGA method, co-developed by IRSTEA these last 10 years. The method, initially set up for the Mediterranean area, is based on a simple event-based hourly hydrologic distributed model run every 15 minutes (Javelle et al. 2014). The hydrologic model ingests operational radar-gauge rainfall grids from Météo-France at a 1-km² resolution to produce discharges for successive outlets along the river network. Discharges are then compared to regionalized flood quantiles of given return periods and warnings (expressed as the range of the return period estimated in real-time) are provided on a river network map. The main interest of the method is to provide forecasters and emergency services with a synthetic view in real time of the ongoing flood situation, information that is especially critical in ungauged flood prone areas. In its enhanced national version, the hourly event-based distributed model is coupled to a continuous daily rainfall-runoff model which provides baseflow and a soil moisture index (for each 1-km² pixel) at the beginning of the hourly simulation. The rainfall-runoff models were calibrated on a selection of 700 French hydrometric stations with Météo-France radar-gauge reanalysis dataset for the 2002-2006 period. To estimate model parameters for ungauged basins, the 2 hydrologic models were regionalised by testing both regressions (using different catchment attributes, such as catchment area, soil type, and climate characteristic) and spatial proximity techniques (transposing parameters from neighbouring donor catchments), as well as different homogeneous hydrological areas. The most valuable regionalisation method was determined for each model through jack-knife cross-validation. The system performance was then

  2. Understanding emotional abuse.

    PubMed

    Rees, C A

    2010-01-01

    Emotional abuse lacks the public and political profile of physical and sexual abuse, despite being at their core and frequently their most damaging dimension. Difficulties in recognition, definition and legal proof put children at risk of remaining in damaging circumstances. Assessment of the emotional environment is necessary when interpreting possible physical or sexual abuse and balancing the risks and benefits of intervention. This article considers factors contributing to professional difficulty. It is suggested that understanding emotional abuse from the first principles of the causes and implications of the dysfunctional parent-child relationships it represents can help prevention, recognition and timely intervention. It may facilitate the professional communication needed to build up a picture of emotional abuse and of the emotional context of physical and sexual abuse. Doing so may contribute to the safety of child protection practice. The long-term cost of emotional abuse for individuals and society should be a powerful incentive for ensuring that development of services and clinical research are priorities, and that the false economy of short-term saving is avoided.

    More weather radar applications have been used to provide accurate precipitation information for flood warning purposes because radar tends to have wider spatial and temporal coverage over the conventional monitoring networks. Thus the radar-based flood warning systems as great tools have become more prevalent in the past decades to provide the information necessary to mobilize the evacuation of people and property prior to flooding in critical areas The Rice University and the Texas Medical Center (TMC) Flood Alert System (FAS) has been providing important warning information for the critical medical facilities for more than 40 events since 1997. The current FAS utilizes NEXRAD Level II radar rainfall data coupled with a real-time hydrologic model (RTHEC-1) to deliver warning information with 2 to 3 hours of lead time and a forecast R2 value of 93% to facility personnel in readily understood format. The latest version - FAS3 has a user-friendly dashboard to provide rainfall maps, Google Maps based inundation maps, hydrologic predictions, and real-time monitoring at the bayou. This paper will discuss its reliable performance during the recent events occurring in 2012. Due to its excellent performance, Texas Medical Center has included FAS3 into their FEMA Success Story as a good example to demonstrate the significant value of the radar-based flood warning system. Currently, the radar-based flood alert system has been used as a platform to develop for other flood-prone areas in Texas.

    1993-01-01

    The United States Geological Survey (USGS) and the National Weather Service (NWS) have developed an operational warning system for debris flows during severe rainstorms in the San Francisco Bay region. The NWS makes quantitative forecasts of precipitation from storm systems approaching the Bay area and coordinates a regional network of radio-telemetered rain gages. The USGS has formulated thresholds for the intensity and duration of rainfall required to initiate debris flows. The first successful public warnings were issued during a severe storm sequence in February 1986. Continued operation of the warning system since 1986 has provided valuable working experience in rainfall forecasting and monitoring, refined rainfall thresholds, and streamlined procedures for issuing public warnings. Advisory statements issued since 1986 are summarized.

    2007-01-01

    The atmosphere within the work setting speaks volumes about your culture, and is often a primary factor in recruitment and retention (or turnover) of staff. Workplace tension and abuse are significant contributing factors as to why nurses are exiting workplaces--and even leaving the profession. Abuse can take many forms from inappropriate interpersonal communication to sexual harassment and even violence. Administrators should adopt a zero tolerance policy towards abusive communication. Addressing peer behavior is essential, but positive behavior must also be authentically modeled from the CNO and other nursing leaders. Raising awareness and holding individuals accountable for their behavior can lead to a safer and more harmonious work environment.

  9. Tsunami Warning Services for the U.S. and Canadian Atlantic Coasts

    2008-12-01

    In January 2005, the National Oceanic and Atmospheric Administration (NOAA) developed a tsunami warning program for the U.S. Atlantic and Gulf of Mexico coasts. Within a year, this program extended further to the Atlantic coast of Canada and the Caribbean Sea. Warning services are provided to U.S. and Canadian coasts (including Puerto Rico and the Virgin Islands) by the NOAA/West Coast and Alaska Tsunami Warning Center (WCATWC) while the NOAA/Pacific Tsunami Warning Center (PTWC) provides services for non-U.S. entities in the Caribbean Basin. The Puerto Rico Seismic Network (PRSN) is also an active partner in the Caribbean Basin warning system. While the nature of the tsunami threat in the Atlantic Basin is different than in the Pacific, the warning system philosophy is similar. That is, initial messages are based strictly on seismic data so that information is provided to those at greatest risk as fast as possible while supplementary messages are refined with sea level observations and forecasts when possible. The Tsunami Warning Centers (TWCs) acquire regional seismic data through many agencies, such as the United States Geological Survey, Earthquakes Canada, regional seismic networks, and the PRSN. Seismic data quantity and quality are generally sufficient throughout most of the Atlantic area-of-responsibility to issue initial information within five minutes of origin time. Sea level data are mainly provided by the NOAA/National Ocean Service. Coastal tide gage coverage is generally denser along the Atlantic coast than in the Pacific. Seven deep ocean pressure sensors (DARTs), operated by the National Weather Service (NWS) National Data Buoy Center, are located in the Atlantic Basin (5 in the Atlantic Ocean, 1 in the Caribbean, and 1 in the Gulf of Mexico). The DARTs provide TWCs with the means to verify tsunami generation in the Atlantic and provide critical data with which to calibrate forecast models.

    This paper presents a survey of technologies useful in providing early warning in physical security systems. Early warning is important in virtually all types of security systems whether they are used for temporary (tactical, portable, or semi-permanent) applications, border warning, fixed-site detection, or standoff surveillance detection. With the exception of the standoff surveillance detection systems, all systems discussed in this paper usually involve a moving target. The fact that a person(s) to be detected in a standoff surveillance scenario is not moving presents challenging problems and requires different applications of technology. The technologies commonly used to detect moving targets and some suggestions for detection of stationary targets are addressed in this paper.

    Wilner, D. O.; Bever, G. A.

    1984-01-01

    The development and testing of a stall-speed warning system for the OV-1C was examined. NASA designed and built an automated stall-speed warning system which presents both airspeed and stall speed to the pilot. The airspeed and stall speed are computed in real time by monitoring the basic aerodynamic parameters (dynamic pressure, horizontal and vertical accelerations, and pressure altitude) and other parameters (elevator and flap positions, engine torques, and fuel flow). In addition, an aural warning at predetermined stall margins is presented to the pilot through a voice synthesizer. Once the system was designed and installed in the aircraft, a flight-test program of less than 20 hrs was anticipated to determine the stall-speed software coefficients. These coefficients would then be inserted in the system's software and then test flown over a period of about 10 hr for the purpose of evaluation.

  12. A SDMS Model: Early Warning Coordination Centres

    Santos-Reyes, Jaime

    2010-05-01

    Following the tsunami disaster in 2004, the General Secretary of the United Nations (UN) Kofi Annan called for a global early warning system for all hazards and for all communities. He also requested the ISDR (International Strategy fort Disaster Reduction) and its UN partners to conduct a global survey of capacities, gaps and opportunities in relation to early warning systems. The produced report, "Global survey of Early Warning Systems", concluded that there are many gaps and shortcomings and that much progress has been made on early warning systems and great capabilities are available around the world. However, it may be argued that an early warning system (EWS) may not be enough to prevent fatalities due to a natural hazard; i.e., it should be seen as part of a ‘wider' or total system. Furthermore, an EWS may work very well when assessed individually but it is not clear whether it will contribute to accomplish the purpose of the ‘total disaster management system'; i.e., to prevent fatalities. For instance, a regional EWS may only work if it is well co-ordinated with the local warning and emergency response systems that ensure that the warning is received, communicated and acted upon by the potentially affected communities. It may be argued that without these local measures being in place, a regional EWS will have little impact in saving lives. Researchers argued that unless people are warned in remote areas, the technology is useless; for instance McGuire [5] argues that: "I have no doubt that the technical element of the warning system will work very well,"…"But there has to be an effective and efficient communications cascade from the warning centre to the fisherman on the beach and his family and the bar owners." Similarly, McFadden [6] states that: "There's no point in spending all the money on a fancy monitoring and a fancy analysis system unless we can make sure the infrastructure for the broadcast system is there,"… "That's going to require a lot

    2004-01-01

    This paper presents a conceptual analysis of dynamic hazard warning systems. The normative aspects of responses to warnings are analyzed, and a distinction is made between two forms of responses to a warning system, referred to as compliance and reliance. Determinants of the responses to warnings are identified, and they are broadly classified into normative, task, and operator factors. Existing research on warnings and automation is assessed in view of this conceptual framework, and directions for future research are discussed. Some implications of this analysis for practitioners, designers, and researchers are indicated. Actual or potential applications of this research include recommendations for the analysis, design, and study of dynamic warning systems.

    Jaedicke, Christian; Syre, Egil; Sverdrup-Thygeson, Kjetil

    2014-05-01

    Avalanche warning for large areas requires the processing of an extensive amount of data. Information relating to the three basic requirements for avalanche warning - knowledge of terrain, the snow conditions, and the weather - needs to be available for the forecaster. The information is highly variable in time. The form and visualization of the data is often decisive for the use by the avalanche forecasters and therefore also for the quality of the produced forecasts. Avalanche warnings can be issued at different scales from national to regional and down to object specific. Often the same warning service is working at different scales and for different clients requiring a flexible and scalable approach. The workflow for producing avalanche forecasts must be extremely efficient - all the way from acquiring observation data, evaluating the situation, down to publishing the new forecast. In this study it has been an aim to include the entire workflow in a single web application. A Geographic Information Systems (GIS) solution was chosen to include all data needed by the forecaster for the avalanche danger evaluation. This interactive system of maps features background information for the entire country, such as topographic maps, slope steepness, aspect, hill shades and satellite images. In each avalanche warning area, all active avalanche paths are plotted including information on wind exposure. Each avalanche path is linked to a webpage with more details, such as fall height, release area elevation and pictures. The avalanche path webpage also includes information on the object at risk e.g. buildings, roads, or other objects. Thus, the forecaster can easily get an overview on the overall situation and focus on single avalanche paths to generate detailed avalanche warnings for the client.

    In Indonesia, an ongoing government "war on drugs" has resulted in numerous arrests and anecdotal reports of abuse in detention, but to date there has been little documentation or analysis of this issue. JANGKAR (also known in English as the Indonesian Harm Reduction Network), a nongovernmental organization (NGO) based in Jakarta, surveyed 1106 injecting drug users in 13 cities about their experiences of police abuse. Of those interviewed, 667 or 60% reported physical abuse by police. These findings indicate the importance of continuing efforts to promote police reform and harm reduction in Indonesia.

    The media play an important role in practice, policy, and public perception of child sexual abuse, in part by the way in which news stories are framed. Child sexual abuse media coverage over the past 50 years can be divided into five time periods based on the types of stories that garnered news coverage and the ways in which public policy was changed. This systematic literature review of research on child sexual abuse media coverage across disciplines and geographic boundaries examines 16 studies published in the English language from 1995 to 2012. A seminal work is identified, citation network analysis is applied, and a framework model is developed. PMID:25635896

    This study examines factors which contribute to elderly abuse and neglect by caregivers in a domestic setting. Methodological and conceptual variations and problems in previous studies have led to considerable confusion as to the determinants of this important social problem. A more rigorous research design was used in this study than has been previously employed. Fifty-nine abused elders from a model project site for the study of elderly abuse were compared with forty-nine non-abused clients from a home care program in the same agency. Using a research instrument designed by the authors, data related to the following aspects of the lives of the elders and their caregivers were collected: psychological status, stressful life events, social networks, mutual dependency, and the nature of their relationships. The study indicates that members of abusive families are more likely to have emotional problems which contribute to interpersonal difficulties. Abused elders are not more dependent on caregivers for many of their daily needs. However, the abused elderly and their caregivers have become increasingly interdependent prior to the onset of abuse because of the loss of other family members, increased social isolation, and the increased financial dependency of the perpetrator on the elderly person.

    Current medications for drug abuse have had only limited success. Anti-addiction vaccines to elicit antibodies that block the pharmacological effects of drugs have great potential for treating drug abuse. We review the status for two vaccines that are undergoing clinical trials (cocaine and nicotine) and two that are still in pre-clinical development (methamphetamine and heroin). We also outline the challenges and ethical concerns for anti-addiction vaccine development and their use as future therapeutics. PMID:22130115

    The abuse of synthetic cathinones, widely known as bath salts, has been increasing since the mid-2000s. These substances are derivatives of the naturally occurring compound cathinone, which is the primary psychoactive component of khat. The toxicity of synthetic cathinones includes significant sympathomimetic effects, as well as psychosis, agitation, aggression, and sometimes violent and bizarre behavior. Mephedrone and methylenedioxypyrovalerone are currently the predominantly abused synthetic cathinones. PMID:23869180

    The last decade demonstrated that seismic waves and tsunamis are coupled to the ionosphere. Observations of Total Electron Content (TEC) and airglow perturbations of unique quality and amplitude were made during the Tohoku, 2011 giant Japan quake, and observations of much lower tsunamis down to a few cm in sea uplift are now routinely done, including for the Kuril 2006, Samoa 2009, Chili 2010, Haida Gwai 2012 tsunamis. This new branch of seismology is now mature enough to tackle the new challenge associated to the inversion of these data, with either the goal to provide from these data maps or profile of the earth surface vertical displacement (and therefore crucial information for tsunami warning system) or inversion, with ground and ionospheric data set, of the various parameters (atmospheric sound speed, viscosity, collision frequencies) controlling the coupling between the surface, lower atmosphere and the ionosphere. We first present the state of the art in the modeling of the tsunami-atmospheric coupling, including in terms of slight perturbation in the tsunami phase and group velocity and dependance of the coupling strength with local time, ocean depth and season. We then show the confrontation of modelled signals with observations. For tsunami, this is made with the different type of measurement having proven ionospheric tsunami detection over the last 5 years (ground and space GPS, Airglow), while we focus on GPS and GOCE observation for seismic waves. These observation systems allowed to track the propagation of the signal from the ground (with GPS and seismometers) to the neutral atmosphere (with infrasound sensors and GOCE drag measurement) to the ionosphere (with GPS TEC and airglow among other ionospheric sounding techniques). Modelling with different techniques (normal modes, spectral element methods, finite differences) are used and shown. While the fits of the waveform are generally very good, we analyse the differences and draw direction of future

    Many buildings have been damaged due to earthquakes that occurred recently in Indonesia. The main cause of the damage is the large deformation of the building structural component cannot accommodate properly. Therefore, it is necessary to develop the Structural Health Monitoring System (SHMS) to measure precisely the deformation of the building structural component in the real time conditions. This paper presents the development of SHMS for reinforced concrete structural system. This monitoring system is based on deformation component such as strain of reinforcement bar, concrete strain, and displacement of reinforced concrete component. Since the deformation component has exceeded the limit value, the warning message can be sent to the building occupies. This warning message has also can be performed as early warning system of the reinforced concrete structural system. The warning message can also be sent via Short Message Service (SMS) through the Global System for Mobile Communications (GSM) network. Hence, the SHMS should be integrated with internet modem to connect with GSM network. Additionally, the SHMS program is verified with experimental study of simply supported reinforced concrete beam. Verification results show that the SHMS has good agreement with experimental results.

  20. Tsunami Warning in the Near Field: the Approach in Hawai'i

    Hawai`i could suffer an earthquake so slow that, like Nicaragua 1992, not even residents on the immediate coast would be alarmed. With so little time for warning, we cannot wait for water-level confirmation of a tsunami. All shallow (<20 km) Hawaiian earthquakes larger than MW=6.5 are thrust events on or near a volcano's basal décollement. These will be tsunamigenic if close to the shoreline. If we assume a thrust mechanism, tsunami warning will require only epicenter and magnitude information and a crude depth determination (is the hypocenter shallower or deeper than 20 km?). By far the most reliable rapid magnitude measurement is MWP, made from the initial few tens of seconds of the P-arrival on broadband seismographs. For a large Kona earthquake, however, the sole broadband station on Hawai`i will be clipped, forcing us to measure MWP from the severely-restricted range perspective provided by the only other broadband stations: on `Oahu. To rectify this situation, broadband seismometers are being installed on all the major islands. With the new network, warnings (initially made assuming shallow depth) will be possible within two minutes of earthquake origin time. By combining information from co-located accelerometers and an expanding short-period network, our goal is to reduce the time-to-warning to 90 seconds for any earthquake within the Hawaiian Islands. With Mauna Loa slowly awakening and the possibility that volcano inflation might drive a great basal-slip earthquake, our target is to achieve 90-second warning within two years.

  18. Thermoregulation constrains effective warning signal expression.

    PubMed

    Lindstedt, Carita; Lindström, Leena; Mappes, Johanna

    2009-02-01

    Evolution of conspicuous signals may be constrained if animal coloration has nonsignaling as well as signaling functions. In aposematic wood tiger moth (Parasemia plantaginis) larvae, the size of a warning signal (orange patch on black body) varies phenotypically and genetically. Although a large warning signal is favored as an antipredator defense, we hypothesized that thermoregulation may constrain the signal size in colder habitats. To test this hypothesis, we conducted a factorial rearing experiment with two selection lines for larval coloration (small and large signal) and with two temperature manipulations (high and low temperature environment). Temperature constrained the size and brightness of the warning signal. Larvae with a small signal had an advantage in the colder environment, which was demonstrated by a faster development time and growth rate in the low temperature treatment, compared to larvae with a large signal. Interestingly, the larvae with a small signal were found more often on the plant than the ones with a large signal, suggesting higher basking activity of the melanic (small signal) individuals in the low temperature. We conclude that the expression of aposematic display is not only defined by its efficacy against predators; variation in temperature may constrain evolution of a conspicuous warning signal and maintain variation in it.

  1. Real-time earthquake monitoring: Early warning and rapid response

    NASA Technical Reports Server (NTRS)

    1991-01-01

    A panel was established to investigate the subject of real-time earthquake monitoring (RTEM) and suggest recommendations on the feasibility of using a real-time earthquake warning system to mitigate earthquake damage in regions of the United States. The findings of the investigation and the related recommendations are described in this report. A brief review of existing real-time seismic systems is presented with particular emphasis given to the current California seismic networks. Specific applications of a real-time monitoring system are discussed along with issues related to system deployment and technical feasibility. In addition, several non-technical considerations are addressed including cost-benefit analysis, public perceptions, safety, and liability.

  2. Hybrid Intrusion Forecasting Framework for Early Warning System

    NASA Astrophysics Data System (ADS)

    Kim, Sehun; Shin, Seong-Jun; Kim, Hyunwoo; Kwon, Ki Hoon; Han, Younggoo

    Recently, cyber attacks have become a serious hindrance to the stability of Internet. These attacks exploit interconnectivity of networks, propagate in an instant, and have become more sophisticated and evolutionary. Traditional Internet security systems such as firewalls, IDS and IPS are limited in terms of detecting recent cyber attacks in advance as these systems respond to Internet attacks only after the attacks inflict serious damage. In this paper, we propose a hybrid intrusion forecasting system framework for an early warning system. The proposed system utilizes three types of forecasting methods: time-series analysis, probabilistic modeling, and data mining method. By combining these methods, it is possible to take advantage of the forecasting technique of each while overcoming their drawbacks. Experimental results show that the hybrid intrusion forecasting method outperforms each of three forecasting methods.

    2009-12-01

    The U.S. government embarked on a strengthening program for the U.S. Tsunami Warning System (TWS) in the aftermath of the disastrous 2004 Indian Ocean tsunami. The program was designed to improve several facets of the U.S. TWS, including: upgrade of the coastal sea level network - 16 new stations plus higher transmission rates; expansion of the deep ocean tsunameter network - 7 sites increased to 39; upgrade of seismic networks - both USGS and Tsunami Warning Center (TWC); increase of TWC staff to allow 24x7 coverage at two centers; development of an improved tsunami forecast system; increased preparedness in coastal communities; expansion of the Pacific Tsunami Warning Center facility; and improvement of the tsunami data archive effort at the National Geophysical Data Center. The strengthening program has been completed and has contributed to the many improvements attained in the U.S. TWS since 2004. Some of the more significant enhancements to the program are: the number of sea level and seismic sites worldwide available to the TWCs has more than doubled; the TWC areas-of-responsibility expanded to include the U.S./Canadian Atlantic coasts, Indian Ocean, Caribbean Sea, Gulf of Mexico, and U.S. Arctic coast; event response time decreased by approximately one-half; product accuracy has improved; a tsunami forecast system developed by NOAA capable of forecasting inundation during an event has been delivered to the TWCs; warning areas are now defined by pre-computed or forecasted threat versus distance or travel time, significantly reducing the amount of coast put in a warning; new warning dissemination techniques have been implemented to reach a broader audience in less time; tsunami product content better reflects the expected impact level; the number of TsunamiReady communities has quadrupled; and the historical data archive has increased in quantity and accuracy. In addition to the strengthening program, the U.S. National Tsunami Hazard Mitigation Program (NTHMP

  11. REWSET: A prototype seismic and tsunami early warning system in Rhodes island, Greece

    NASA Astrophysics Data System (ADS)

    Papadopoulos, Gerasimos; Argyris, Ilias; Aggelou, Savvas; Karastathis, Vasilis

    2014-05-01

    Tsunami warning in near-field conditions is a critical issue in the Mediterranean Sea since the most important tsunami sources are situated within tsunami wave travel times starting from about five minutes. The project NEARTOWARN (2012-2013) supported by the EU-DG ECHO contributed substantially to the development of new tools for the near-field tsunami early warning in the Mediterranean. One of the main achievements is the development of a local warning system in the test-site of Rhodes island (Rhodes Early Warning System for Earthquakes and Tsunamis - REWSET). The system is composed by three main subsystems: (1) a network of eight seismic early warning devices installed in four different localities of the island, one in the civil protection, another in the Fire Brigade and another two in municipality buildings; (2) two radar-type (ultrasonic) tide-gauges installed in the eastern coastal zine of the island which was selected since research on the historical earthquake and tsunami activity has indicated that the most important, near-field tsunami sources are situated offshore to the east of Rhodes; (3) a crisis Geographic Management System (GMS), which is a web-based and GIS-based application incorporating a variety of thematic maps and other information types. The seismic early warning devices activate by strong (magnitude around 6 or more) earthquakes occurring at distances up to about 100 km from Rhodes, thus providing immediate mobilization of the civil protection. The tide-gauges transmit sea level data, while during the crisis the GMS supports decisions to be made by civil protection. In the near future it is planned the REWSET system to be integrated with national and international systems. REWSET is a prototype which certainly could be developed in other coastal areas of the Mediterranean and beyond.

  12. [Trauma repetition and revictimization following physical and sexual abuse].

    PubMed

    Wöller, W

    2005-02-01

    The tendency of victims of physical or sexual childhood abuse to become revictimized in later life has well been documented empirically. Moreover, there is a high stability of violent and abusive relationships. The aim of this paper was to summarize perspectives from psychodynamic theory, attachment theory, and posttraumatic stress research to explain revictimization phenomena. The term repetition compulsion has little explanatory value without additional theoretical assumptions. Within the psychodynamic framework, an ego-psychological view conceives trauma repetition as an attempt to master traumatic experience, while in the object relations perspective, revictimization is explained by the influence of traumatic introjects. Negative cognitions of being worthless, bad and guilty can endorse the conviction that abuse is justified and reduce the capacity of self-care. Negative learning experiences from traumatic helplessness and powerlessness account for low self-efficacy expectations and prevent the establishment of self-boundaries. Trauma repetition can also be understood as an enactment in the service of affect regulation. Research in the field of attachment theory identified attachment styles predisposing to revictimization. Research dealing with posttraumatic stress disorder emphasizes the importance of traumatic affects recurring in daily life and, consequently, the tendency of abuse victims to actively produce dangerous situations in order to cope with these affects, furthermore, the role of dissociation in missing warning signals of impending traumatization. For therapeutically addressing revictimization, a detailed analysis of underlying phenomena is required. PMID:15685492

  14. A Filter Bank Approach to Earthquake Early Warning

    NASA Astrophysics Data System (ADS)

    Meier, Men-Andrin; Heaton, Tom; Clinton, John

    2014-05-01

    Earthquake Early Warning (EEW) is a race against time. The longer it takes to detect and characterize an ongoing event, the larger is the blind zone - the region where a warning arrives only after the most damaging ground motion has occurred. The problem is most acute during medium size earthquakes, where damaging ground motion is confined to a small zone around the epicenter. An ideal EEW algorithm which is fast enough to provide relevant alerts for such scenario events would have to produce reliable event characterization based on observations of very short snippets of data recorded at only very few stations. For such a scheme to work, without significant numbers of false alarms (which continue to hamper both single-station and network based approaches today), the real-time information that is available for an earthquake has to be exploited in a more optimal way than what is currently done. Our approach is to fully mine the broadband frequency content of incoming waveforms that contains significant information on the size and epicentral distance of the ongoing event. We propose a filter bank approach with minimum phase delay filters which allows us to use frequency information from each frequency band at each triggered station at the earliest possible time. We have compiled and processed an extensive dataset of near-field earthquake waveforms. In an empirical maximum likelihood scheme, we use the filter bank output from the first seconds after the P-wave onset of each waveform to estimate the most likely magnitude and epicentral distance to have caused this waveform. We show how our single station approach can be integrated into an evolutionary and fully probabilistic network EEW system. We demonstrate that our method can allow sufficiently accurate characterization of an ongoing event with two stations, with consistent characterization of the evolving uncertainty of the location and magnitude.

  15. Abuse of medications that theoretically are without abuse potential.

    PubMed

    Reeves, Roy R; Ladner, Mark E; Perry, Candace L; Burke, Randy S; Laizer, Janet T

    2015-03-01

    The potential for abuse of medications that are controlled substances is well known. Abuse of certain noncontrolled prescription drugs and over-the-counter medications also may occur. To some degree, any medication that exerts psychoactive effects may be abused if taken in high enough doses or by means that result in high serum or cerebrospinal fluid levels. Many clinicians may be unaware of the potential for abuse of these medications. This review examines evidence of the possibility of abuse of several common medications that theoretically do not have abuse potential, including cough and cold preparations, antihistamines, anticholinergics, antipsychotics, antidepressants, anticonvulsants, skeletal muscle relaxants, and antiemetics. Means by which such medications may be abused and biochemical and physiological mechanisms fostering their abuse also are discussed.

  16. An online operational rainfall-monitoring resource for epidemic malaria early warning systems in Africa

    USGS Publications Warehouse

    Grover-Kopec, Emily; Kawano, Mika; Klaver, Robert W.; Blumenthal, Benno; Ceccato, Pietro; Connor, Stephen J.

    2005-01-01

    The Roll Back Malaria Technical Resource Network on Prevention and Control of Epidemics recommended that a simple indicator of changes in epidemic risk in regions of marginal transmission, consisting primarily of rainfall anomaly maps, could provide immediate benefit to early warning efforts. In response to these recommendations, the Famine Early Warning Systems Network produced maps that combine information about dekadal rainfall anomalies, and epidemic malaria risk, available via their Africa Data Dissemination Service. These maps were later made available in a format that is directly compatible with HealthMapper, the mapping and surveillance software developed by the WHO's Communicable Disease Surveillance and Response Department. A new monitoring interface has recently been developed at the International Research Institute for Climate Prediction (IRI) that enables the user to gain a more contextual perspective of the current rainfall estimates by comparing them to previous seasons and climatological averages. These resources are available at no cost to the user and are updated on a routine basis.

  17. The complexities of elder abuse.

    PubMed

    Roberto, Karen A

    2016-01-01

    Elder abuse is a growing societal concern, affecting at least 1 in 10 older Americans. Researchers and practitioners alike consistently assert that a dramatic discrepancy exists between the prevalence rates of elder abuse and the number of elder abuse cases reported. As a field of study, recognition and understanding of elder abuse is still emerging. Comparing findings of a small, but growing, body of literature on perceived and substantiated cases of elder abuse is challenging because there is no uniform term or agreed-upon definition used among state governments, researchers, health care and service providers, and advocates. This article summarizes current understanding of elder abuse, including what constitutes elder abuse, risk factors for elder abuse, perpetrators of elder abuse, and outcomes of elder abuse. Issues associated with the detection of elder abuse and intervention strategies for victims of abuse are addressed. In the final section, potential roles and contributions of psychologists for advancing elder abuse research, professional practice, and policy development are highlighted. (PsycINFO Database Record

    The DEWS (Distant Early Warning System) [1] project, funded under the 6th Framework Programme of the European Union, has the objective to create a new generation of interoperable early warning systems based on an open sensor platform. This platform integrates OGC [2] SWE [3] compliant sensor systems for the rapid detection of earthquakes, for the monitoring of sea level, ocean floor events, and ground displacements. Based on the upstream information flow DEWS focuses on the improvement of downstream capacities of warning centres especially by improving information logistics for effective and targeted warning message aggregation for a multilingual environment. Multiple telecommunication channels will be used for the dissemination of warning messages. Wherever possible, existing standards have been integrated. The Command and Control User Interface (CCUI), a rich client application based on Eclipse RCP (Rich Client Platform) [4] and the open source GIS uDig [5], integrates various OGC services. Using WMS (Web Map Service) [6] and WFS (Web Feature Service) [7] spatial data are utilized to depict the situation picture and to integrate a simulation system via WPS (Web Processing Service) [8] to identify affected areas. Warning messages are compiled and transmitted in the OASIS [9] CAP (Common Alerting Protocol) [10] standard together with addressing information defined via EDXL-DE (Emergency Data Exchange Language - Distribution Element) [11]. Internal interfaces are realized with SOAP [12] web services. Based on results of GITEWS [13] - in particular the GITEWS Tsunami Service Bus [14] - the DEWS approach provides an implementation for tsunami early warning systems. The introductory part of the demonstration briefly explains the DEWS project, the CCUI in conjunction with operators’ workflow, the system architecture, details of information logistics and the virtual scenario of live demonstration.

    This paper describes the development of the Flash Flood Manager, abbreviated as FlaFloM. The Flash Flood Manager is an early warning system for flash floods which is developed under the EU LIFE project FlaFloM. It is applied to Wadi Watier located in the Sinai peninsula (Egypt) and discharges in the Red Sea at the local economic and tourist hub of Nuweiba city. FlaFloM consists of a chain of four modules: 1) Data gathering module, 2) Forecasting module, 3) Decision support module or DSS and 4) Warning module. Each module processes input data and consequently send the output to the following module. In case of a flash flood emergency, the final outcome of FlaFloM is a flood warning which is sent out to decision-makers. The ‘data gathering module’ collects input data from different sources, validates the input, visualise data and exports it to other modules. Input data is provided ideally as water stage (h), discharge (Q) and rainfall (R) through real-time field measurements and external forecasts. This project, however, as occurs in many arid flash flood prone areas, was confronted with a scarcity of data, and insufficient insight in the characteristics that release a flash flood. Hence, discharge and water stage data were not available. Although rainfall measurements are available through classical off line rain gauges, the sparse rain gauges network couldn’t catch the spatial and temporal characteristics of rainfall events. To overcome this bottleneck, we developed rainfall intensity raster maps (mm/hr) with an hourly time step and raster cell of 1*1km. These maps are derived through downscaling from two sources of global instruments: the weather research and forecasting model (WRF) and satellite estimates from the Tropical Rainfall Measuring Mission (TRMM). The ‘forecast module’ comprises three numerical models that, using data from the gathering module performs simulations on command: a rainfall-runoff model, a river flow model, and a flood model. A

    Context Since drug-involved women are among the fastest growing groups with AIDS, sexual risk reduction intervention for them is a public health imperative. Objective Test effectiveness of HIV/STD safer sex skills building (SSB) groups for women in community drug treatment. Design Randomized trial of SSB versus standard HIV/STD Education (HE); assessments at baseline, 3- and 6- months Participants Women recruited from 12 methadone or psychosocial treatment programs in NIDA’s Clinical Trials Network. 515 women with ≥ one unprotected vaginal or anal sex occasion (USO) with a male partner in the past 6 months were randomized. Interventions In SSB, five 90-minute groups used problem-solving and skills rehearsal to increase HIV/STD risk awareness, condom use and partner negotiation skills. In HE, one 60-minute group covered HIV/STD disease, testing, treatment, and prevention information. Main Outcome Number of USOs at follow up. Results A significant difference in mean USOs was obtained between SSB and HE over time (F=67.2, p<.0001). At 3 months, significant decrements were observed in both conditions. At 6 months SSB maintained the decrease, HE returned to baseline (p<.0377). Women in SSB had 29% fewer USOs than those in HE. Conclusions Skills building interventions can produce ongoing sexual risk reduction in women in community drug treatment. PMID:18645513

    Despite recent advances in behavioral interventions for cannabis use disorders, effect sizes remain modest, and few individuals achieve long-term abstinence. One strategy to enhance outcomes is the addition of pharmacotherapy to complement behavioral treatment, but to date no efficacious medications targeting cannabis use disorders in adults through large, randomized controlled trials have been identified. The National Institute on Drug Abuse Clinical Trials Network (NIDA CTN) is currently conducting a study to test the efficacy of N-acetylcysteine (NAC) versus placebo (PBO), added to contingency management, for cannabis cessation in adults (ages 18–50). This study was designed to replicate positive findings from a study in cannabis-dependent adolescents that found greater odds of abstinence with NAC compared to PBO. This paper describes the design and implementation of an ongoing 12-week, intent-to-treat, double-blind, randomized, placebo-controlled study with one follow-up visit four weeks post-treatment. Approximately 300 treatment-seeking cannabis-dependent adults will be randomized to NAC or PBO across six study sites in the United States. The primary objective of this 12-week study is to evaluate the efficacy of twice-daily orally-administered NAC (1200 mg) versus matched PBO, added to contingency management, on cannabis abstinence. NAC is among the first medications to demonstrate increased odds of abstinence in a randomized controlled study among cannabis users in any age group. The current study will assess the cannabis cessation efficacy of NAC combined with a behavioral intervention in adults, providing a novel and timely contribution to the evidence base for the treatment of cannabis use disorders.

    Recent federal legislation and a renewed focus on integrative care models underscore the need for economical, effective, and science-based behavioral health care treatment. As such, maximizing the impact and reach of treatment research is of great concern. Behavioral health issues, including the frequent co-occurrence of substance use disorders (SUD) and posttraumatic stress disorder (PTSD), are often complex, with a myriad of factors contributing to the success of interventions. Although treatment guides for comorbid SUD/PTSD exist, most patients continue to suffer symptoms following the prescribed treatment course. Further, the study of efficacious treatments has been hampered by methodological challenges (e.g., overreliance on “superiority” designs (i.e., designs structured to test whether or not one treatment statistically surpasses another in terms of effect sizes) and short term interventions). Secondary analyses of randomized controlled clinical trials offer potential benefits to enhance understanding of findings and increase the personalization of treatment. This paper offers a description of the limits of randomized controlled trials as related to SUD/PTSD populations, highlights the benefits and potential pitfalls of secondary analytic techniques, and uses a case example of one of the largest effectiveness trials of behavioral treatment for co-occurring SUD/PTSD conducted within the National Drug Abuse Treatment Clinical Trials Network (NIDA CTN) and producing 19 publications. The paper concludes with implications of this secondary analytic approach to improve addiction researchers’ ability to identify best practices for community-based treatment of these disorders. Innovative methods are needed to maximize the benefits of clinical studies and better support SUD/PTSD treatment options for both specialty and non-specialty healthcare settings. Moving forward, planning for and description of secondary analyses in randomized trials should be given equal

    Rapid detection of compact binary coalescence (CBC) with a network of advanced gravitational-wave detectors will offer a unique opportunity for multi-messenger astronomy. Prompt detection alerts for the astronomical community might make it possible to observe the onset of electromagnetic emission from CBC. We demonstrate a computationally practical filtering strategy that could produce early-warning triggers before gravitational radiation from the final merger has arrived at the detectors.

    Overcrowding of emergency departments impedes health care access and quality nationwide. A real-time early warning system for overcrowding may allow administrators to alleviate the problem before reaching a crisis state. Two original probabilistic models – a logistic regression and a recurrent neural network – were created to predict overcrowding crises one hour in the future. The two original and two pre-existing models were validated at 8,496 observation points from January 1, 2006 to February 28, 2006. All models showed high discriminatory ability in terms of area under the receiver operating characteristic curve (logistic regression = .954; recurrent neural network = .957; EDWIN = .879; NEDOCS = .924). At comparable rates of false alarms, the logistic regression gave more advance notice of crises than other models (logistic regression = 62 min; recurrent neural network = 13 min; EDWIN = 0 min; NEDOCS = 0 min). These results demonstrate the feasibility of using models based on key operational variables to anticipate overcrowding crises in real time. PMID:17238359

    Pediatricians and other medical providers caring for children need to be aware of the dynamics in the significant relationship between substance abuse and child maltreatment. A caregiver's use and abuse of alcohol, marijuana, heroin, cocaine, methamphetamine, and other drugs place the child at risk in multiple ways. Members of the medical community need to understand these risks because the medical community plays a unique and important role in identifying and caring for these children. Substance abuse includes the abuse of legal drugs as well as the use of illegal drugs. The abuse of legal substances may be just as detrimental to parental functioning as abuse of illicit substances. Many substance abusers are also polysubstance users and the compounded effect of the abuse of multiple substances may be difficult to measure. Often other interrelated social features, such as untreated mental illness, trauma history, and domestic violence, affect these families.

    Marijuana has a long history of abuse yet, as described here by Mary Abood and Billy Martin, there is little evidence that animals will self-administer the primary psychoactive constituent, tetrahydrocannabinol, or that marijuana stimulates brain reward pathways. While marked tolerance develops to marijuana, it has been difficult to demonstrate physical dependence, and until recently the mechanisms by which cannabinoids produced their behavioral effects were poorly defined. The development of new synthetic analogs played a critical role in the characterization and cloning of the cannabinoid receptor. Insight into cannabinoid receptors may lead to a better understanding of marijuana abuse in humans and provide new therapeutic strategies for several disorders.

    The Message Impact Framework suggests that social interactions may offer smokers the opportunity to process pictorial warnings on cigarette packs more deeply. We aimed to describe adult smokers' social interactions about pictorial cigarette pack warnings in two longitudinal pilot studies. In Pilot Study 1, 30 smokers used cigarette packs with one of nine pictorial warnings for two weeks. In Pilot Study 2, 46 smokers used cigarette packs with one of five pictorial warnings for four weeks. Nearly all smokers (97%/96% in Pilot Study 1/2) talked about the warnings with other people, with the most common people being friends (67%/87%) and spouses/significant others (34%/42%). Pilot Study 2 found that 26% of smokers talked about the warnings with strangers. Discussions about the health effects of smoking and quitting smoking were more frequent during the first week of exposure to pictorial warnings than in the week prior to beginning the study (both p < 0.05). Pictorial warnings sparked social interactions about the warnings, the health effects of smoking, and quitting smoking, indicating that pictorial warnings may act as a social intervention reaching beyond the individual. Future research should examine social interactions as a potential mediator of the impact of pictorial warnings on smoking behavior. PMID:26506363

    network. We estimate the time required for P-waves generated by subduction zone earthquakes to reach the number of stations typically needed to produce a tsunami warning. We then project these data to the nearest coastlines to produce a table of P-wave reception times for earthquakes affecting these coastlines. Next, we subtract these reception time values from the travel time of tsunamis from these earthquakes to the coastlines. The resulting data sets and corresponding maps reveal the time window of opportunity for populations to act upon PTWC's warnings and safely evacuate these coastal areas. Our maps show that while most of the world's coastal populations have an hour or more to evacuate after receiving a warning from PTWC, certain coastlines have less than an hour, and in the worst cases, the first tsunami wave will arrive before PTWC can warn the affected areas. While our analysis reveals response problems for a given tsunami warning center, it also highlights the solutions by indicating where to install and monitor additional seismic stations, and where data outages could have the greatest negative impact, thus showing where redundancy in station deployment is most critical.

  18. Flash flood warnings for ungauged basins based on high-resolution precipitation forecasts

    Early detection of flash floods, which are typically triggered by severe rainfall events, is still challenging due to large meteorological and hydrologic uncertainties at the spatial and temporal scales of interest. Also the rapid rising of waters necessarily limits the lead time of warnings to alert communities and activate effective emergency procedures. To better anticipate such events and mitigate their impacts, the French national service in charge of flood forecasting (SCHAPI) is implementing a national flash flood warning system for small-to-medium (up to 1000 km²) ungauged basins based on a discharge-threshold flood warning method called AIGA (Javelle et al. 2014). The current deterministic AIGA system has been run in real-time in the South of France since 2005 and has been tested in the RHYTMME project (rhytmme.irstea.fr/). It ingests the operational radar-gauge QPE grids from Météo-France to run a simplified hourly distributed hydrologic model at a 1-km² resolution every 15 minutes. This produces real-time peak discharge estimates along the river network, which are subsequently compared to regionalized flood frequency estimates to provide warnings according to the AIGA-estimated return period of the ongoing event. The calibration and regionalization of the hydrologic model has been recently enhanced for implementing the national flash flood warning system for the entire French territory by 2016. To further extend the effective warning lead time, the flash flood warning system is being enhanced to ingest Météo-France's AROME-NWC high-resolution precipitation nowcasts. The AROME-NWC system combines the most recent available observations with forecasts from the nowcasting version of the AROME convection-permitting model (Auger et al. 2015). AROME-NWC pre-operational deterministic precipitation forecasts, produced every hour at a 2.5-km resolution for a 6-hr forecast horizon, were provided for 3 significant rain events in September and November 2014 and

    Two experiments with voice warning systems (VWS), one in a helicopter UH-1D and the other one in a F 104 flight simulator are described. In the first experiment recognition times to identify simulated failures were measured in cruise and low level flights with 5 pilots. It was proved that voice warnings compared to light warnings do reduce recognition time. This is especially true during low level flight, and when only precise warning texts are used. In the second experiment the interaction of voice warnings and radio communication was investigated. Eleven pilots had to do a navigation flight and to react with correct emergency procedures when failures were introduced. Reaction times suggest that additional light warnings tend to slow down pilots reactions. The findings stress the possibility that the pilot might become overloaded when voice warnings do occur while radio communication is going on.

    OBJECTIVE To provide estimates of physical abuse and use of health services among depressed women in order to inform efforts to increase detection and treatment of physical abuse. DESIGN Retrospective assessment of abuse and health services use over 1 year in a cohort of depressed women. SETTING Statewide community sample from Arkansas. PARTICIPANTS We recruited 303 depressed women through random-digit-dial screening. MEASUREMENTS AND MAIN RESULTS Exposure to physical abuse based on the Conflict Tactics Scale, multi-informant estimate of health and mental health services. Over half of the depressed women (55.2%) reported experiencing physical abuse as adults, with 14.5% reporting abuse during the study year. Women abused as adults had significantly more severe depressive symptoms, more psychiatric comorbidity, and more physical illnesses than nonabused women. After controlling for sociodemographic and severity-of-illness factors, recently abused, depressed women were much less likely to receive outpatient care for mental health problems as compared to other depressed women (odds ratio [OR] 0.3;p = .013), though they were more likely to receive health care for physical problems (OR 5.7, p = .021). CONCLUSIONS Because nearly all depressed women experiencing abuse sought general medical rather than mental health care during the year of the study, primary care screening for physical abuse appears to be a critical link to professional help for abused, depressed women. Research is needed to inform primary care guidelines about methods for detecting abuse in depressed women. PMID:9754516

    In the past decades, China has observed rapid urbanization, the nation's urban population reached 50% in 2000, and is still in steady increase. Rapid urbanization in China has an adverse impact on urban hydrological processes, particularly in increasing the urban flood risks and causing serious urban flooding losses. Urban flooding also increases health risks such as causing epidemic disease break out, polluting drinking water and damaging the living environment. In the highly urbanized area, non-engineering measurement is the main way for managing urban flood risk, such as flood risk warning. There is no mature method and pilot study for urban flood risk warning, the purpose of this study is to propose the urban flood risk warning method for the rapidly urbanized Chinese cities. This paper first presented an urban flood forecasting model, which produces urban flood inundation index for urban flood risk warning. The model has 5 modules. The drainage system and grid dividing module divides the whole city terrain into drainage systems according to its first-order river system, and delineates the drainage system into grids based on the spatial structure with irregular gridding technique; the precipitation assimilation module assimilates precipitation for every grids which is used as the model input, which could either be the radar based precipitation estimation or interpolated one from rain gauges; runoff production module classifies the surface into pervious and impervious surface, and employs different methods to calculate the runoff respectively; surface runoff routing module routes the surface runoff and determines the inundation index. The routing on surface grid is calculated according to the two dimensional shallow water unsteady flow algorithm, the routing on land channel and special channel is calculated according to the one dimensional unsteady flow algorithm.

    In disaster management scientists must transmit their results to large groups of recipients, including decision makers and the mass media who often are not familiar with the language of science. The importance of the promotion of the hydrologic risk perception of the user communities is that many events have short lead times and high levels of uncertainty. Natural hazard mitigation processes are complex and demand several perspectives. While the rhetoric calls for extensive collaboration between disciplines, the gap between theory and practice is large, particularly in the U.S. This paper highlights results from case studies of collaborative flood warning research in Europe and in USA. Case studies on warning systems from Italy and the U.S. are included.

    2015-12-01

    From the early of this year, the Korea Meteorological Administration (KMA) began to operate the first stage of an earthquake early warning system (EEWS) and provide early warning information to the general public. The earthquake early warning system (EEWS) in the KMA is based on the Earthquake Alarm Systems version 2 (ElarmS-2), developed at the University of California Berkeley. This method estimates the earthquake location using a simple grid search algorithm that finds the location with the minimum variance of the origin time on successively finer grids. A robust maximum likelihood earthquake location (MAXEL) method for early warning, based on the equal differential times of P arrivals, was recently developed. The MAXEL has been demonstrated to be successful in determining the event location, even when an outlier is included in the small number of P arrivals. This presentation details the application of the MAXEL to the EEWS of the KMA, its performance evaluation over seismic networks in South Korea with synthetic data, and comparison of statistics of earthquake locations based on the ElarmS-2 and the MAXEL.

    This original qualitative research inquiry is based on a phenomenological research dissertation case study. This article information and content that is gathered helps to better inform providers in the field of social services and those who are social workers and administrators in social services. This research investigated key factors, traits, or attributes that strive to improve service care for women of domestic violence abuse. Findings support current and relevant research to enhance aid to women of abuse. Results strongly detail that professionals must work more cooperatively as an all-channels network of comprehensive care to women. Because women of domestic violence abuse require such multifaced complex care due to the interwoven issues familial abuse brings, results support that service practitioners can best meet the needs of these women through an ecological or life-space understanding for improved care, achieved by infusing an inter-disciplinary systems-based, inter-agency and intra-agency framework.

    Complex dynamical systems, ranging from ecosystems to financial markets and the climate, can have tipping points at which a sudden shift to a contrasting dynamical regime may occur. Although predicting such critical points before they are reached is extremely difficult, work in different scientific fields is now suggesting the existence of generic early-warning signals that may indicate for a wide class of systems if a critical threshold is approaching.

    On April 23, 2014, the Food and Drug Administration (FDA) issued a letter of warning that injection of corticosteroids into the epidural space of the spine may result in rare, but serious adverse events, including "loss of vision, stroke, paralysis, and death." The advisory also advocated that patients should discuss the benefits and risks of epidural corticosteroid injections with their health care professionals, along with the benefits and risks associated with other possible treatments. In addition, the FDA stated that the effectiveness and safety of the corticosteroids for epidural use have not been established, and the FDA has not approved corticosteroids for such use. To raise awareness of the risks of epidural corticosteroid injections in the medical community, the FDA's Safe Use Initiative convened a panel of experts including pain management experts to help define the techniques for such injections with the aim of reducing preventable harm. The panel was unable to reach an agreement on 20 proposed items related to technical aspects of performing epidural injections. Subsequently, the FDA issued the above referenced warning and a notice that a panel will be convened in November 2014. This review assesses the inaccuracies of the warning and critically analyzes the available literature. The literature has been assessed in reference to alternate techniques and an understanding of the risk factors when performing transforaminal epidural injections in the cervical, thoracic, and lumbar regions, ultimately resulting in improved safety. The results of this review show the efficacy of epidural injections, with or without steroids, in a multitude of spinal ailments utilizing caudal, cervical, thoracic, and lumbar interlaminar approaches as well as lumbar transforaminal epidural injections . The evidence also shows the superiority of steroids in managing lumbar disc herniation utilizing caudal and lumbar interlaminar approaches without any significant difference as

    Highway safety is a major concern to the public and to transportation professionals, so the number of crashes caused by poor visibility due to fog form an alarming statistic. Drivers respond to poor visibility conditions in different ways: some slow down; others do not. Many drivers simply follow the taillights of the vehicle ahead. Accordingly, hazardous conditions are created in which speeds are both too high for the prevailing conditions and highly variable. Findings are presented from a study of traffic crashes due to fog in the southern region of Saudi Arabia. The primary objective was to assess the effectiveness of fog detection and warning system on driver behavior regarding speed and headway. This warning system includes visibility sensors that automatically activate a variable message sign that posts an advisory speed when hazardous conditions due to fog occur. The system was installed on a 2 km section of a two-lane, rural highway. A data set of 36,013 observations from both experimental and control sections at two study sites was collected and analyzed. The data included vehicle speed, volume, and classification; time headway, time of day, and visibility distance. Although the warning system was ineffective in reducing speed variability, mean speed throughout the experimental sections was reduced by about 6.5 kph. This reduction indicates that the warning system appeared to have a positive effect on driver behavior in fog even though the observed mean speeds were still higher than the posted advisory speed. From relationships found in the literature between mean driving speed and number of crashes, a speed reduction of only 5 kph would yield a 15% decrease in the number of crashes.

    The current study examined the rate and psychiatric correlates of sexual abuse involving the use of digital technologies by the offender in a wide sample of juvenile victims. Sociodemographic, abuse, and psychiatric characteristics of 662 sexually abused children and adolescents were evaluated. Of these, 93 reported that digital devices were used by the offender in several ways to facilitate the sexual abuse. The offender-victim relationship was initiated through the Internet in 39 victims. Involvement of digital technologies in sexual abuse was significantly associated with penetrative and recurrent form of sexual abuse commited by multiple offenders with coexisting violence. Additionally, victims of sexual abuse with a digital component were 4.21 times more likely to develop any psychopathology, 3.77 times more likely to have depression, and 2.14 times more likely to have post-traumatic stress disorder as a result of sexual abuse. These results indicated that the offender's use of digital technology may aid the initiation and facilitation of the sexual abuse of youths and may relate to more severe outcomes. This study revealed the importance of raising the awareness of professionals and the community about the potential risks associated with digital technologies and sexual abuse. Mental health professionals should consider this additional form of victimization, especially when dealing with sexual abuse victims.

    2009-01-01

    Objective: To demonstrate a real-life correlation that after the US Food and Drug Administration introduced a boxed warning concerning malignancies to the labeling for topical calcineurin inhibitors, reluctance to use topical calcineurin inhibitors has led to their substitution with other therapies that have their own risks. Participants: An anonymous survey of attendees of the 2007 Fall Clinical Dermatology conference in Las Vegas, Nevada, from October 17–19, 2007. More than 95 percent of attendees were dermatologists; a small number of mid-level practitioners attended as well. Of nearly 700 attendees, the first 504 who agreed to complete the survey were included. Results: More than 40 percent of dermatologists surveyed claimed that more than 20 percent of their atopic dermatitis patients are not adequately controlled since the introduction of the boxed warning. Forty-eight percent claim that more than 20 percent of those patients were adequately controlled with topical calcineurin inhibitors as part of their regimens. Eighty percent of dermatologists surveyed agree that more than 10 precent of those patients were adequately controlled with topical calcineurin inhibitors in their regimens. Conclusion: While caution is usually prudent, the introduction of a boxed warning in the case of topical calcineurin inhibitors has led to the use of treatments that often have greater risks than the topical calcineurin inhibitors that they replaced.

    Interpersonal types among alcohol abusers were examined with Calsyn, Roszell, and Anderson's (1988) nine-type system for classifying FIRO-B profiles. The frequencies of the nine FIRO-B types among a sample of 135 male veteran alcohol abusers were compared with Calsyn et al.'s (1988) previously published data for a sample of male veteran drug abusers, a normative veteran sample, and a general population sample. The alcohol abusers, like Calsyn et al.'s sample of drug abusers, were more likely to be categorized as "loners," "rebels," and "pessimists" than was the general population sample. While exhibiting preferences for interpersonal types that emphasized social withdrawal, avoidance of responsibility, and mistrust of others, both the alcohol abusers and the drug abusers were heterogeneous groups whose members demonstrated a variety of interpersonal types.

  5. A comparison of different informative vibrotactile forward collision warnings: does the warning need to be linked to the collision event?

    2014-01-01

    Recent research demonstrates that auditory and vibrotactile forward collision warnings presenting a motion signal (e.g., looming or apparent motion across the body surface) can facilitate speeded braking reaction times (BRTs). The purpose of the present study was to expand on this work by directly comparing warning signals in which the motion conveyed was constant across all collision events with signals in which the speed of motion was dependent on the closing velocity (CV). Two experiments were conducted using a simulated car-following task and BRTs were measured. In Experiment 1, increasing intensity (looming) vibrotactile signals were presented from a single tactor attached to the driver's waist. When the increase in intensity was CV-linked, BRTs were significantly faster as compared to a no-warning condition, however, they were not significantly different from constant intensity and CV-independent looming warnings. In Experiment 2, a vertical array of three tactors was used to create motion either towards (upwards) or away (downwards) from the driver's head. When the warning signal presented upwards motion that was CV-linked, BRTs were significantly faster than all other warning types. Downwards warnings led to a significantly higher number of brake activations in false alarm situations as compared to upwards moving warnings. The effectiveness of dynamic tactile collision warnings would therefore appear to depend on both the link between the warning and collision event and on the directionality of the warning signal.

    Research on warning labels printed on cigarette packages has shown that fear inducing health warnings might provoke defensive responses. This study investigated whether reformulating statements into questions could avoid defensive reactions. Smokers were presented with either warning labels formulated as questions, textual warning labels, graphic warning labels, or no warning labels. Participants' smoking-related risk perception was higher after exposure to warning labels formulated as questions or no warning labels than after exposure to textual or graphic warning labels. These results indicate that reformulating statements into questions can avoid defensive responses elicited by textual- and graphic warning labels. PMID:22419415

    2015-02-01

    Drug abuse is a common problem and growing concern in the United States, and over the past decade, novel or atypical drugs have emerged and have become increasingly popular. Recognition and treatment of new drugs of abuse pose many challenges for health care providers due to lack of quantitative reporting and routine surveillance, and the difficulty of detection in routine blood and urine analyses. Furthermore, street manufacturers are able to rapidly adapt and develop new synthetic isolates of older drugs as soon as law enforcement agencies render them illegal. In this article, we describe the clinical and adverse effects and purported pharmacology of several new classes of drugs of abuse including synthetic cannabinoids, synthetic cathinones, salvia, desomorphine, and kratom. Because many of these substances can have severe or life-threatening adverse effects, knowledge of general toxicology is key in recognizing acute intoxication and overdose; however, typical toxidromes (e.g., cholinergic, sympathomimetic, opioid, etc.) are not precipitated by many of these agents. Medical management of patients who abuse or overdose on these drugs largely consists of supportive care, although naloxone may be used as an antidote for desomorphine overdose. Symptoms of aggression and psychosis may be treated with sedation (benzodiazepines, propofol) and antipsychotics (haloperidol or atypical agents such as quetiapine or ziprasidone). Other facets of management to consider include treatment for withdrawal or addiction, nutrition support, and potential for transmission of infectious diseases. PMID:25471045

    The article focuses on countries and areas of South-East Asia, which are seriously affected by drug abuse and the problems associated with it. Opium has traditionally been used for treating illnesses and alleviating physical and mental stress, as well as for recreational and social purposes. The prohibition of the sale and use of opium in Burma, Hong Kong, Malaysia, Singapore and Thailand forced many habitual opium users to switch to heroin. Over the past two decades there has been an increasing trend towards drug use, often involving experimentation with more than one substance, among youth in and out of school. For example, a survey of students at teachers' colleges in northern Thailand showed that at some time in their lives 30-40 per cent of the male respondents and 3-6 per cent of the female respondents had used cannabis, and that 18-20 per cent of the males and 12-27 per cent of the females had sniffed volatile solvents. The same survey showed that 5-10 per cent of both the males and females had used stimulants and nearly 2 per cent had used heroin. During the 1970s the abuse of heroin and other opiates emerged as a serious problem of epidemic nature, predominantly affecting young people in many countries of South-East Asia. While opiates, including heroin, have been abused by inhaling and by smoking, there has recently been an increasing trend towards injecting heroin of high purity (80-90 per cent pure heroin). Heroin addiction spread first to the populations of capital cities and then to other cities and towns and even to the hill tribes, as studies in Thailand have revealed. Most recent studies have shown that heroin abuse has spread further in Asia, both socially and geographically, involving such countries as India and Sri Lanka, which had no previous experience with the problem.

    Among the social and medical ills of the twentieth century, substance abuse ranks as on one of the most devastating and costly. The drug problem today is a major global concern including Bangladesh. Almost all addictive drugs over stimulate the reward system of the brain, flooding it with the neurotransmitter dopamine. That produces euphoria and that heightened pleasure can be so compelling that the brain wants that feeling back again and again. However repetitive exposure induces widespread adaptive changes in the brain. As a consequence drug use may become compulsive. An estimated 4.7% of the global population aged 15 to 64 or 184 million people, consume illicit drug annually. Heroin use alone is responsible for the epidemic number of new cases of HIV/AIDS, Hepatitis and drug addicted infant born each year. Department of narcotic control (DNC) in Bangladesh reported in June 2008 that about 5 million drug addicts in the country & addicts spend at least 17 (Seventeen) billion on drugs per year. Among these drug addicts, 91% are young and adolescents population. Heroin is the most widely abused drugs in Bangladesh. For geographical reason like India, Pakistan and Myanmar; Bangladesh is also an important transit root for internationally trafficking of illicit drug. Drug abuse is responsible for decreased job productivity and attendance increased health care costs, and escalations of domestic violence and violent crimes. Drug addiction is a preventable disease. Through scientific advances we now know much more about how exactly drugs work in the brain, and we also know that drug addiction can be successfully treated to help people stop abusing drugs and resume their productive lives. Most countries have legislation designed to criminalize some drugs. To decrease the prevalence of this problem in our setting; increase awareness, promoting additional research on abused and addictive drugs, and exact implementation of existing laws are strongly recommended.

    With more than 25 million people at risk from high hazard faults in California alone, Earthquake Early Warning (EEW) presents a promising public safety and emergency response tool. EEW represents the real-time end of an earthquake information spectrum which also includes near real-time notifications of earthquake location, magnitude, and shaking levels; as well as geographic information system (GIS)-based products for compiling and visually displaying processed earthquake data such as ShakeMap and ShakeCast. Improvements to and increased multi-national implementation of EEW have stimulated interest in how such information products could be used in the future. Lifeline organizations, consisting of utilities and transportation systems, can use both onsite and regional EEW information as part of their risk management and public safety programs. Regional EEW information can provide improved situational awareness to system operators before automatic system protection devices activate, and allow trained personnel to take precautionary measures. On-site EEW is used for earthquake-actuated automatic gas shutoff valves, triggered garage door openers at fire stations, system controls, etc. While there is no public policy framework for preemptive, precautionary electricity or gas service shutdowns by utilities in the United States, gas shut-off devices are being required at the building owner level by some local governments. In the transportation sector, high-speed rail systems have already demonstrated the ‘proof of concept’ for EEW in several countries, and more EEW systems are being installed. Recently the Bay Area Rapid Transit District (BART) began collaborating with the California Integrated Seismic Network (CISN) and others to assess the potential benefits of EEW technology to mass transit operations and emergency response in the San Francisco Bay region. A key issue in this assessment is that significant earthquakes are likely to occur close to or within the BART

    As an integrated observing strategy, the concept of sensorweb for Earth observations is appealing in many aspects. For instance, by increasing the spatial and temporal coverage of observations from space and other vantage points, one can eventually aid in increasing the accuracy of the atmospheric models which are precursor to hurricane track prediction, volcanic eruption forecast, and trajectory path of transcontinental transport of dust, harmful nuclear and chemical plumes. In reality, there is little analysis'available in terms of benefits, costs and optimized set of sensors needed to make these necessary observations. This is a complex problem that must be carefully studied and balanced over many boundaries such as science, defense, early warning, security, and surveillance. Simplistically, the sensorweb concept from the technological point of view alone has a great appeal in the defense, early warning and security applications. In fact, it can be relatively less expensive in per unit cost as opposed to building and deploying it for the scientific use. However, overall observing approach should not be singled out and aligned somewhat orthogonally to serve a particular need. On the other hand, the sensorweb should be designed and deployed to serve multiple subject areas and customers simultaneously; and can behave as directed measuring systems for both science and operational entities. Sensorweb can be designed to act as expert systems, and/or also provide a dedicated integrated surveillance network. Today, there is no system in the world that is fully integrated in terms of reporting timely multiple hazards warnings, computing the loss of life and property damage estimates, and is also designed to cater to everyone's needs.

In recent years, it has become necessary to factor in the effects of a changing climate as well. There has also been a growing appreciation of the linkage between food security and water availability. In 2009, Famine Early Warning Systems Network (FEWS NET) science partners began developing land surface modeling (LSM) applications to address these needs. With support from the NASA Applied Sciences Program, an instance of the Land Information System (LIS) was developed to specifically support FEWS NET. A simple crop water balance model (GeoWRSI) traditionally used by FEWS NET took its place alongside the Noah land surface model and the latest version of the Variable Infiltration Capacity (VIC) model, and LIS data readers were developed for FEWS NET precipitation forcings (NOAA's RFE and USGS/UCSB's CHIRPS). The resulting system was successfully used to monitor and project soil moisture conditions in the Horn of Africa, foretelling poor crop outcomes in the OND 2013 and MAM 2014 seasons. In parallel, NOAA created another instance of LIS to monitor snow water resources in Afghanistan, which are an early indicator of water availability for irrigation and crop production. These successes have been followed by investment in LSM implementations to track and project water availability in Sub-Saharan Africa and Yemen, work that is now underway. Adoption of

  5. An Envelope-Based Paradigm for Seismic Early Warning

    We present a waveform envelope-based paradigm for seismic early warning. As suggested by theoretical scaling relations and as observed from data, acceleration saturates with increasing magnitude at a faster rate than does velocity or displacement. Thus, ratios of velocity or displacement to acceleration should be indicative of the magnitude of an earthquake. We introduce an evenlope-based parameterization of ground motion, where the observed ground motion envelope is decomposed into independent P-wave, S-wave, and ambient noise envelopes. The body wave envelopes, in turn, are parameterized by a rise time, an amplitude, a duration, and two decay parameters. We apply this parameterization to a database of over 30,000 records of horizontal and vertical acceleration, velocity, and displacement recorded on digital Southern California Seismic Network stations within 200 km of 80 regional events ranging in magnitude from M2.0 to M7.3. We derive attenuation relationships that account for magnitude-dependent saturation for vertical and horizontal acceleration, velocity, and displacement for P- and S-wave amplitudes, obtain station corrections relative to the mean hard rock response, and use these relationships to examine trends with magnitude and distance of ratios of different components of ground motion. An important consequence of our parameterization is the insight it provides into P-wave characteristics. We find that various ratios of P-wave velocity and displacement to acceleration are indicative of magnitude, and may have potential as another quick method to estimate magnitude for seismic early warning.

  6. Tactile warning signals for in-vehicle systems.

    The last few years have seen growing interest in the design of tactile warning signals to direct driver attention to potentially dangerous road situations (e.g. an impending crash) so that they can initiate an avoidance maneuver in a timely manner. In this review, we highlight the potential uses of such warning signals for future collision warning systems and compare them with more traditional visual and auditory warnings. Basic tactile warning signals are capable of promoting driver alertness, which has been demonstrated to be beneficial for forward collision avoidance (when compared to a no warning baseline condition). However, beyond their basic alerting function, directional tactile warning signals are now increasingly being utilized to shift the attention of the driver toward locations of interest, and thus to further facilitate their speeded responses to potential collision events. Currently, many researchers are focusing their efforts on the development of meaningful (iconic) tactile warning signals. For instance, dynamic tactile warnings (varying in their intensity and/or location) can potentially be used to convey meaningful information to drivers. Finally, we highlight the future research that will be needed in order to explore how to present multiple directional warnings using dynamic tactile cues, thus forming an integrated collision avoidance system for future in-vehicle use.

  7. Will abuse-deterrent formulations of opioid analgesics be successful in achieving their purpose?

    PubMed

    Bannwarth, Bernard

    2012-09-10

    During the last 2 decades, there has been a dramatic increase in the use of strong opioids for chronic non-cancer pain. This increase has been accompanied by a steep increase in abuse, misuse, and both fatal and non-fatal overdoses involving prescription opioids. The situation is already alarming in the US. Prescription opioid-related harm is a complex, multifactorial issue that requires a multifaceted solution. In this respect, formulations of opioid analgesics designed to resist or deter abuse may be a useful component of a comprehensive opioid risk minimization programme. Such formulations have or are being developed. Abuse-resistant opioids include those that use some kind of physical barrier to prevent tampering with the formulation. Abuse-deterrent opioids are not necessarily resistant to tampering, but contain substances that are designed to make the formulation less attractive to abusers. This article focuses on two products intended to deter abuse that were reviewed by the US Food and Drug Administration (FDA). The first (Embeda®) consists of extended-release morphine with sequestered naltrexone, an opioid antagonist that is released if the tablet is compromised by chewing or crushing. Although Embeda® exhibited abuse-deterrent features, its label warns that it can be abused in a manner similar to other opioid agonists. Furthermore, tampering with Embeda® will result in the release of naltrexone, which may precipitate withdrawal in opioid-tolerant individuals. In March 2011, all dosage forms of Embeda® were recalled because the product failed to meet routine stability standards, and its return date to the market is currently unknown. The second product (Acurox®) was intended to be both tamper resistant and abuse deterrent. It consisted of an immediate-release oxycodone tablet with subtherapeutic niacin as an aversive agent and used a gel-forming ingredient designed to inhibit inhalation and prevent extraction of the drug for injection.

    Childhood maltreatment is a stressor that can lead to the development of behavior problems and affect brain structure and function. This review summarizes the current evidence for the effects of childhood maltreatment on behavior, cognition and the brain in adults and children. Neuropsychological studies suggest an association between child abuse and deficits in IQ, memory, working memory, attention, response inhibition and emotion discrimination. Structural neuroimaging studies provide evidence for deficits in brain volume, gray and white matter of several regions, most prominently the dorsolateral and ventromedial prefrontal cortex but also hippocampus, amygdala, and corpus callosum (CC). Diffusion tensor imaging (DTI) studies show evidence for deficits in structural interregional connectivity between these areas, suggesting neural network abnormalities. Functional imaging studies support this evidence by reporting atypical activation in the same brain regions during response inhibition, working memory, and emotion processing. There are, however, several limitations of the abuse research literature which are discussed, most prominently the lack of control for co-morbid psychiatric disorders, which make it difficult to disentangle which of the above effects are due to maltreatment, the associated psychiatric conditions or a combination or interaction between both. Overall, the better controlled studies that show a direct correlation between childhood abuse and brain measures suggest that the most prominent deficits associated with early childhood abuse are in the function and structure of lateral and ventromedial fronto-limbic brain areas and networks that mediate behavioral and affect control. Future, large scale multimodal neuroimaging studies in medication-naïve subjects, however, are needed that control for psychiatric co-morbidities in order to elucidate the structural and functional brain sequelae that are associated with early environmental adversity

    The Geodetic Alarm System (G-larmS) is a software system developed in a collaboration between the Berkeley Seismological Laboratory (BSL) and New Mexico Tech (NMT) primarily for real-time Earthquake Early Warning (EEW). It currently uses high rate (1Hz), low latency (< ~5 seconds), accurate positioning (cm level) time series data from a regional GPS network and P-wave event triggers from existing EEW algorithms, e.g. ElarmS, to compute static offsets upon S-wave arrival. G-larmS performs a least squares inversion on these offsets to determine slip on a finite fault, which we use to estimate moment magnitude. These computations are repeated every second for the duration of the event. G-larmS has been in continuous operation at the BSL for over a year using event triggers from the California Integrated Seismic Network (CISN) ShakeAlert system and real-time position time series from a fully triangulated network consisting of BARD, PBO and USGS stations across northern California. Pairs of stations are processed as baselines using trackRT (MIT software package). G-larmS produced good results in real-time during the South Napa (M 6.0, August 2014) earthquake as well as on several replayed and simulated test cases. We evaluate the performance of G-larmS for EEW by analysing the results using a set of well defined test cases to investigate the following: (1) using multiple fault regimes and concurrent processing with the ultimate goal of achieving model generation (slip and magnitude computations) within each 1 second GPS epoch on very large magnitude earthquakes (up to M 9.0), (2) the use of Precise Point Positioning (PPP) real-time data streams of various operators, accuracies, latencies and formats along with baseline data streams, (3) collaboratively expanding EEW coverage along the U.S. West Coast on a regional network basis for Northern California, Southern California and Cascadia.

    Early tsunami warning critically hinges on rapid determination of the tsunami hazard potential in real-time, before waves inundate critical coastlines. Tsunami energy can quickly characterize the destructive potential of generated waves. Traditional seismic analysis is inadequate to accurately predict a tsunami's energy. Recently, two independent approaches have been proposed to determine tsunami source energy: one inverted from the Deep-ocean Assessment and Reporting of Tsunamis (DART) data during the tsunami propagation, and the other derived from the land-based coastal global positioning system (GPS) during tsunami generation. Here, we focus on assessing these two approaches with data from the March 11, 2011 Japanese tsunami. While the GPS approach takes into consideration the dynamic earthquake process, the DART inversion approach provides the actual tsunami energy estimation of the propagating tsunami waves; both approaches lead to consistent energy scales for previously studied tsunamis. Encouraged by these promising results, we examined a real-time approach to determine tsunami source energy by combining these two methods: first, determine the tsunami source from the globally expanding GPS network immediately after an earthquake for near-field early warnings; and then to refine the tsunami energy estimate from nearby DART measurements for improving forecast accuracy and early cancelations. The combination of these two real-time networks may offer an appealing opportunity for: early determination of the tsunami threat for the purpose of saving more lives, and early cancelation of tsunami warnings to avoid unnecessary false alarms.

    Beside structural mitigation measures like avalanche defense structures, dams and galleries, warning and alarm systems have become important measures for dealing with Alpine natural hazards. Integrating them into risk mitigation strategies and comparing their effectiveness with structural measures requires quantification of the reliability of these systems. However, little is known about how reliability of warning systems can be quantified and which methods are suitable for comparing their contribution to risk reduction with that of structural mitigation measures. We present a reliability analysis of a warning system located in Grindelwald, Switzerland. The warning system was built for warning and protecting residents and tourists from glacier outburst floods as consequence of a rapid drain of the glacier lake. We have set up a Bayesian Net (BN, BPN) that allowed for a qualitative and quantitative reliability analysis. The Conditional Probability Tables (CPT) of the BN were determined according to manufacturer's reliability data for each component of the system as well as by assigning weights for specific BN nodes accounting for information flows and decision-making processes of the local safety service. The presented results focus on the two alerting units 'visual acoustic signal' (VAS) and 'alerting of the intervention entities' (AIE). For the summer of 2009, the reliability was determined to be 94 % for the VAS and 83 % for the AEI. The probability of occurrence of a major event was calculated as 0.55 % per day resulting in an overall reliability of 99.967 % for the VAS and 99.906 % for the AEI. We concluded that a failure of the VAS alerting unit would be the consequence of a simultaneous failure of the four probes located in the lake and the gorge. Similarly, we deduced that the AEI would fail either if there were a simultaneous connectivity loss of the mobile and fixed network in Grindelwald, an Internet access loss or a failure of the regional operations

    Fractures and other skeletal injuries are common in childhood. Most are the result of falls, motor vehicle accidents, and other forms of accidental trauma. However, skeletal trauma is present in a significant number of abused children. Age and developmental abilities are key components in raising clinical suspicion for child abuse. Children who are unable to provide their own history because of age or developmental delay require increased attention. Younger children are more likely to have abusive fractures, whereas accidental fractures increase with age and developmental abilities. The consequences of missing abuse are high because children returned to their homes without intervention are likely to face further abuse and have an increased mortality risk. Because of the potentially high cost of undiagnosed child abuse, diagnosis of a skeletal injury is incomplete without diagnosing its etiology. All health providers for children should be able to recognize patterns of skeletal injury secondary to abusive trauma and understand the process for initiating Child Protective Services (CPS) investigations when necessary. Although they can occur accidentally, fractures in nonmobile children should always increase the clinician's concern for abusive trauma. In light of the significant consequences for children when abuse is missed by a primary care provider, abuse should be on the differential diagnosis for all presenting childhood injuries.

    Background Recent studies have suggested that there has been an increase in the number of ‘warning letters’ issued by the US Food and Drug Administration (FDA) despite the publication of the FDA advertising guidelines. However, limited information is available on the description of warning letters. The objective of this study was to analyse the frequency and content of FDA warning letters in relation to promotional claims and discuss the influence of regulatory and industry constraints on promotion. Methods All warning letters published by the FDA between 5 May 1995 and 11 June 2007 were reviewed. Warning letters related to promotional issues were included and analysed. Information related to the identification number, date of the warning letter, FDA division that issued the letter, drug name, manufacturer, specific warning problem, type of promotional material and requested action was extracted. Two independent investigators reviewed and classified each PDF file, any differences were discussed until a consensus was reached. Results Between May 1995 and June 2007 a total of 8692 warning letters were issued, of which 25% were related to drugs. Of these, 206 warning letters focused on drug promotion and were included in this study: 23% were issued in 2005, 15% in 2004 and 14% in 1998. In total, 47% of the warning letters were issued because of false or misleading unapproved doses and uses, 27% failed to disclose risks, 15% cited misleading promotion, 8% related to misleading labelling and 3% promoted false effectiveness claims. Discussion There is an important variation in the number of warning letters issued in the last decade, probably because of the increasing number of drugs approved by the FDA, drug withdrawal scandals, and the publication of the FDA and the Pharmaceutical Research and Manufacturers of America (PhRMA) guidelines. Conclusion We found that benefit-related claims, such as unapproved uses or doses of drugs, and failure to disclose risks, are the

    Objective The use of pictorial warning labels on cigarette packages is one of the provisions included in the first ever global health treaty by the World Health Organization against the tobacco epidemic. There is substantial evidence demonstrating the effectiveness of graphic health warning labels on intention to quit, thoughts about health risks and engaging in cessation behaviors. However, studies that address the implicit emotional drives evoked by such warnings are still underexplored. Here, we provide experimental data for the use of pictorial health warnings as a reliable strategy for tobacco control. Methods Experiment 1 pre-tested nineteen prototypes of pictorial warnings to screen for their emotional impact. Participants (n = 338) were young adults balanced in gender, smoking status and education. Experiment 2 (n = 63) tested pictorial warnings (ten) that were stamped on packs. We employed an innovative set-up to investigate the impact of the warnings on the ordinary attitude of packs’ manipulation, and quantified judgments of warnings’ emotional strength and efficacy against smoking. Findings Experiment 1 revealed that women judged the warning prototypes as more aversive than men, and smokers judged them more aversive than non-smokers. Participants with lower education judged the prototypes more aversive than participants with higher education. Experiment 2 showed that stamped warnings antagonized the appeal of the brands by imposing a cost to manipulate the cigarette packs, especially for smokers. Additionally, participants’ judgments revealed that the more aversive a warning, the more it is perceived as effective against smoking. Conclusions Health warning labels are one of the key components of the integrated approach to control the global tobacco epidemic. The evidence presented in this study adds to the understanding of how implicit responses to pictorial warnings may contribute to behavioral change. PMID:23977223

    As lithium-ion battery technologies mature, the size and energy of these systems continues to increase (> 50 kWh for EVs); making safety and reliability of these high energy systems increasingly important. While most material advances for lithium-ion chemistries are directed toward improving cell performance (capacity, energy, cycle life, etc.), there are a variety of materials advancements that can be made to improve lithium-ion battery safety. Issues including energetic thermal runaway, electrolyte decomposition and flammability, anode SEI stability, and cell-level abuse tolerance continue to be critical safety concerns. This report highlights work with our collaborators to develop advanced materials to improve lithium-ion battery safety and abuse tolerance and to perform cell-level characterization of new materials.

    Blood banks and transfusion services should anticipate that patients contracting transfusion-transmitted diseases will claim that these facilities have a duty to warn or notify patients of potential transfusion risks. Although physicians treating patients must secure informed consent by describing significant risks and possible alternatives, precedent does not support extending informed consent requirements to the hospital or blood bank. Nonetheless, efforts to find new sources of compensation may cause judges to develop new theories of liability. Blood bank and transfusion service medical directors, therefore, are advised to provide clinicians with information regarding current or emerging transfusion risks and alternatives such as autologous transfusion, urging communication to patients when informed consent is obtained.

    An obstacle warning radar concept for helicopters is described in both the test and operational phases. A radar sonde is mounted on the front of the helicopter under a radome and senses the atmosphere forward over a range of 180 deg azimuth and 32 deg elevation. The ray is directed by a fast-rotating mirror, resulting in an image-renewal rate of two per second. Obstacles can be detected to a distance of 800 m. depending on atmospheric conditions and obstacle size.

    Scenes in movies where smoking occurs have been empirically shown to influence teenagers to smoke cigarettes. The capacity of a Canadian warning label on cigarette packages to decrease the effects of smoking scenes in popular movies has been investigated. A 2 x 3 factorial design was used to test the effects of the same movie scene with or without electronic manipulation of all elements related to smoking, and cigarette pack warnings, i.e., no warning, text-only warning, and text+picture warning. Smoking-related stereotypes and intent to smoke of teenagers were measured. It was found that, in the absence of warning, and in the presence of smoking scenes, teenagers showed positive smoking-related stereotypes. However, these effects were not observed if the teenagers were first exposed to a picture and text warning. Also, smoking-related stereotypes mediated the relationship of the combined presentation of a text and picture warning and a smoking scene on teenagers' intent to smoke. Effectiveness of Canadian warning labels to prevent or to decrease cigarette smoking among teenagers is discussed, and areas of research are proposed. PMID:17450995

    This experiment investigated the influence of warnings, signal words, and a signal icon on perceived hazard of consumer products. Under the guise of a marketing research study, 135 people (high school students, college students, and participants from a shopping mall) rated product labels on six dimensions, including how hazardous they perceived the products to be. A total of 16 labels from actual household products were used: 9 carried the experimental conditions, and 7 were filler product labels that never carried a warning. Five conditions presented the signal words NOTE, CAUTION, WARNING, DANGER, and LETHAL together with a brief warning message. In another two conditions, a signal icon (exclamation point surrounded by a triangle) was presented together with the terms DANGER and LETHAL. In the final two conditions, one lacked a signal word but retained the warning message, and the other lacked both the warning message and the signal word. Results showed that the presence of a signal word increased perceived product hazard compared with its absence. Significant differences were noted between extreme terms (e.g., NOTE and DANGER) but not between terms usually recommended in warning design guidelines (e.g., CAUTION and WARNING). The signal icon showed no significant effect on hazard perception. Implications of the results and the value of the methodology for future warnings investigations are discussed. PMID:7989055

    A Smart Grid is a cyber-based tool to facilitate a network of sensors for monitoring and communicating the landslide hazard and providing the early warning. The sensor is designed as an electronic sensor installed in the existing monitoring and early warning instruments, and also as the human sensors which comprise selected committed-people at the local community, such as the local surveyor, local observer, member of the local task force for disaster risk reduction, and any person at the local community who has been registered to dedicate their commitments for sending reports related to the landslide symptoms observed at their living environment. This tool is designed to be capable to receive up to thousands of reports/information at the same time through the electronic sensors, text message (mobile phone), the on-line participatory web as well as various social media such as Twitter and Face book. The information that should be recorded/ reported by the sensors is related to the parameters of landslide symptoms, for example the progress of cracks occurrence, ground subsidence or ground deformation. Within 10 minutes, this tool will be able to automatically elaborate and analyse the reported symptoms to predict the landslide hazard and risk levels. The predicted level of hazard/ risk can be sent back to the network of electronic and human sensors as the early warning information. The key parameters indicating the symptoms of landslide hazard were recorded/ monitored by the electrical and the human sensors. Those parameters were identified based on the investigation on geological and geotechnical conditions, supported with the laboratory analysis. The cause and triggering mechanism of landslide in the study area was also analysed in order to define the critical condition to launch the early warning. However, not only the technical but also social system were developed to raise community awareness and commitments to serve the mission as the human sensors, which will

    Cocaine abuse during pregnancy is a significant public health problem but is infrequently discussed between physicians and patients. The impact of in utero cocaine exposure on pregnancy and the baby has received significant media attention in preceding decades because of fears of teratogenicity, long-term health consequences, and poor cognitive and neurodevelopmental outcomes. We sought to review the medical literature examining these phenomena. We identified risks to the pregnancy and baby in women abusing cocaine during pregnancy. These include preterm birth, placenta-associated syndromes (e.g., placental abruption, preeclampsia, and placental infarction), and impaired fetal growth. Long-term neurodevelopmental and cognitive deficits include (but are not limited to) poorer language development, learning and perceptual reasoning, behavioural problems, and adverse effects on memory and executive function. However, these results should be interpreted cautiously because cocaine abuse may be accompanied by many other maternal and sociodemographic risk factors, so it is difficult to ascertain the effect of cocaine alone. Therefore, it is critical to counsel patients about potential risk, and perhaps more importantly, to treat addiction and to better understand, and advocate for improvements to, these patients' high-risk environment.

    Gender differences in substance use disorders (SUDs) and treatment outcomes for women with SUDs have been a focus of research in the last 15 years. This article reviews gender differences in the epidemiology of SUDs, highlighting the convergence of male/female prevalence ratios of SUDs in the last 20 years. The telescoping course of SUDs, recent research on the role of neuroactive gonadal steroid hormones in craving and relapse, and sex differences in stress reactivity and relapse to substance abuse are described. The role of co-occurring mood and anxiety, eating, and posttraumatic stress disorders is considered in the epidemiology, natural history, and treatment of women with SUDs. Women's use of alcohol, stimulants, opioids, cannabis, and nicotine are examined in terms of recent epidemiology, biologic and psychosocial effects, and treatment. Although women may be less likely to enter substance abuse treatment than men over the course of the lifetime, once they enter treatment, gender itself is not a predictor of treatment retention, completion, or outcome. Research on gender-specific treatments for women with SUDs and behavioral couples treatment has yielded promising results for substance abuse treatment outcomes in women.

    Substance abuse continues to be a major adolescent health risk. Despite encouraging trends toward decreased drug use in the late 1980s, an increase in use occurred in the early 1990s and only now is beginning to level off. A brief update on the status of the most commonly abused substances is provided. A discussion of current research is given in support of viewing drug addiction as a medical condition, i.e., a "brain disease." Reasons are suggested to explain why adolescents use and abuse drugs and why trends occur in their use. Two aspects of diagnosis are reviewed: psychiatric and medical comorbidity and drug screening and laboratory assessment of the adolescent. Prevention and early intervention are presented with an emphasis on drug education, behavioral wellness, family communication, doctor-patient discussion and assessment, and referral. Commentary is made on the ethics of care; issues of confidentiality and the right to privacy with regard to drug testing and sharing of information are explored. A review of various policy statements of the American Academy of Pediatrics and other medical organizations is presented.

  16. Drug abuse in athletes

    Drug abuse occurs in all sports and at most levels of competition. Athletic life may lead to drug abuse for a number of reasons, including for performance enhancement, to self-treat otherwise untreated mental illness, and to deal with stressors, such as pressure to perform, injuries, physical pain, and retirement from sport. This review examines the history of doping in athletes, the effects of different classes of substances used for doping, side effects of doping, the role of anti-doping organizations, and treatment of affected athletes. Doping goes back to ancient times, prior to the development of organized sports. Performance-enhancing drugs have continued to evolve, with “advances” in doping strategies driven by improved drug testing detection methods and advances in scientific research that can lead to the discovery and use of substances that may later be banned. Many sports organizations have come to ban the use of performance-enhancing drugs and have very strict consequences for people caught using them. There is variable evidence for the performance-enhancing effects and side effects of the various substances that are used for doping. Drug abuse in athletes should be addressed with preventive measures, education, motivational interviewing, and, when indicated, pharmacologic interventions. PMID:25187752

    by the WERA radars to TEWS. The radar measurements can be used to confirm a pre-warning and raise a tsunami alert. The output data of WERA processing software can be easily integrated into existing TEWS due to flexible data format, fast update rate and quality control of measurements. The archived radar data can be used for further hazard analysis and research purposes. The newly launched Tsunami Warning Center in Oman is one of the most sophisticated tsunami warning system world-wide applying a mix of well proven state-of-the-art subsystems. It allows the acquisition of data from many different sensor systems including seismic stations, GNSS, tide gauges, and WERA ocean radars in one acquisition system providing access to all sensor data via a common interface. The TEWS in Oman also integrates measurements of a modern network of HF ocean radars to verify tsunami simulations, which give additional scenario quality information and confirmation to the decision support.

    The devastating earthquake and tsunami of December 26, 2004 has greatly increased recognition of the need for water level data both from the coasts and the deep-ocean. In 2006, the National Oceanic and Atmospheric Administration (NOAA) completed a Tsunami Data Management Report describing the management of data required to minimize the impact of tsunamis in the United States. One of the major gaps defined in this report is the access to global coastal water level data. NOAA's National Geophysical Data Center (NGDC) and National Climatic Data Center (NCDC) are working cooperatively to bridge this gap. NOAA relies on a network of global data, acquired and processed in real-time to support tsunami detection and warning, as well as high-quality global databases of archived data to support research and advanced scientific modeling. In 2005, parties interested in enhancing the access and use of sea level station data united under the NOAA NCDC's Integrated Data and Environmental Applications (IDEA) Center's Pacific Region Integrated Data Enterprise (PRIDE) program to develop a distributed metadata system describing sea level stations (Kari et. al., 2006; Marra et.al., in press). This effort started with pilot activities in a regional framework and is targeted at tsunami detection and warning systems being developed by various agencies. It includes development of the components of a prototype sea level station metadata web service and accompanying Google Earth-based client application, which use an XML-based schema to expose, at a minimum, information in the NOAA National Weather Service (NWS) Pacific Tsunami Warning Center (PTWC) station database needed to use the PTWC's Tide Tool application. As identified in the Tsunami Data Management Report, the need also exists for long-term retention of the sea level station data. NOAA envisions that the retrospective water level data and metadata will also be available through web services, using an XML-based schema. Five high
