    During 2004, oil prices reached levels unprecedented in recent years. Though world oil markets remain adequately supplied, high oil prices do reflect increasingly uncertain conditions. Many IEA member countries and non-member countries alike are looking for ways to improve their capability to handle market volatility and possible supply disruptions in the future. This book aims to provide assistance. It provides a new, quantitative assessment of the potential oil savings and costs of rapid oil demand restraint measures for transport. Some measures may make sense under any circumstances; others are primarily useful in emergency situations. All can be implemented on short notice ? if governments are prepared. The book examines potential approaches for rapid uptake of telecommuting, ?ecodriving?, and car-pooling, among other measures. It also provides methodologies and data that policymakers can use to decide which measures would be best adapted to their national circumstances. This ?tool box? may help countries to complement other measures for coping with supply disruptions, such as use of strategic oil stocks.

    TMSA is a concept prototype developed to support NASA Test Directors (NTDs) in schedule execution monitoring during the later stages of a Shuttle countdown. The program detects qualitative and quantitative constraint violations in near real-time. The next version will support incremental rescheduling and reason over a substantially larger number of scheduled events.

    One of the basic findings on situation models and language comprehension is that reading times are affected by the changing event structure in a text. However, many studies have traditionally used multiple, relatively short texts, in which there is little event consistency across the texts. It is unclear to what extent such changes will be…

    1993-07-01

    This study examines the variability and stability of coping in cancer subjects over time and situation. In a prospective longitudinal design 74 breastcancer patients have been followed for 3-5 yr at 3-6 monthly intervals. A variety of measures related to coping and adjustment were taken. This report limits itself to the findings of an instrument developed for this study, the Bernese Coping Modes in which 26 coping modes were rated by observers. Results confirm arguments in favour of both variability and stability in coping activity over time and situation. Two measures support stability: rank values and a multivariate measure (MDS) with three constant dimensions: (1) support and acceptance; (2) denial; (3) diversion by thought and action. Evidence for variability is: the potential range of coping modes and a large variety of additional modes at most observation times. Subsequently time measures of coping were attributed to eight predefined illness stages as distinct clinical situations. Thus variability or richness of coping further increased. The implications of these findings for measurement in coping research are discussed.

  6. Saving electricity in a hurry. Dealing with temporary shortfalls in electricity supplies

    Blackouts are normally the result of imbalances in electricity supply and demand. A brief blackout is mostly an inconvenience. But persistent shortfalls ? those lasting days, weeks, or months ? can cause economic disruption and danger to human life in our technology-rich societies. Saving Electricity in a Hurry describes some of the recent power shortfalls, from Norway to New Zealand, from Tokyo to Arizona and the policies these regions used to quickly reduce their power consumption. How did the whole country of Sweden cut its power consumption by 4% in only three days? How did California save 14% in only a few months? While the temporary shortfalls in electricity supplies described in this book are relatively rare events, they disproportionately shape future energy policies. Saving Electricity in a Hurry shows that countries can quickly reduce electricity consumption without harming the economy as much as blackouts or unplanned curtailments. The strategies are diverse, unique and often surprisingly cheap. They include mass media campaigns ? where a good joke can save a Megawatt ? improvements in equipment efficiency and quickly adjusting electricity prices. This book explains how California replaced a million traffic signals with energy-saving models, how millions of Tokyo residents raised their thermostat settings, and how New Zealanders took shorter showers, all quickly enough to help avoid imminent blackouts. Finally, it connects these policies to the traditional goal of ?saving electricity slowly?.

    2010-04-01

    Spatio-temporal reasoning plays a significant role in situation management that is performed by intelligent agents (human or machine) by affecting how the situations are recognized, interpreted, acted upon or predicted. Many definitions and formalisms for the notion of spatio-temporal reasoning have emerged in various research fields including psychology, economics and computer science (computational linguistics, data management, control theory, artificial intelligence and others). In this paper we examine the role of spatio-temporal reasoning in situation management, particularly how to resolve situations that are described by using spatio-temporal relations among events and situations. We discuss a model for describing context sensitive temporal relations and show have the model can be extended for spatial relations.

    Gibson, William L [Los Alamos National Laboratory; Deborah, Leishman, A. [Los Alamos National Laboratory; Van Eeckhout, Edward [Los Alamos National Laboratory

    2008-01-01

    The authors have developed an enhanced Bayesian analysis tool called the Integrated Knowledge Engine (IKE) for monitoring and surveillance. The enhancements are suited for Rapid Response Situations where decisions must be made based on uncertain and incomplete evidence from many diverse and heterogeneous sources. The enhancements extend the probabilistic results of the traditional Bayesian analysis by (1) better quantifying uncertainty arising from model parameter uncertainty and uncertain evidence, (2) optimizing the collection of evidence to reach conclusions more quickly, and (3) allowing the analyst to determine the influence of the remaining evidence that cannot be obtained in the time allowed. These extended features give the analyst and decision maker a better comprehension of the adequacy of the acquired evidence and hence the quality of the hurried decisions. They also describe two example systems where the above features are highlighted.

    The joint influence of persons and situations on behavior has long been posited by personality and social psychological theory (Funder, 2006; Lewin, 1951). However, a lack of tools for real-time behavioral and situation assessment has left direct investigations of this sort immobilized. This study combines recent advances in situation assessment and experience sampling methodology to examine the simultaneous effects of personality traits and situation characteristics on real-time expressions of behavior and emotion in N = 210 participants. The results support an additive model such that both personality traits and situation characteristics independently predict real-time expressions of behavior and emotion. These results have implications for several prominent theoretical perspectives in personality, including both trait and cognitive theories.

    Full Text Available How to provide safe and effective evacuation routes is an important safeguard to correctly guide evacuation and reduce the casualties during the fire situation rapidly evolving in complex indoor environment. The traditional static path finding method is difficult to adjust the path adaptively according to the changing fire situation, which lead to the evacuation decision-making blindness and hysteresis. This paper proposes a dynamic method which can dynamically optimize the indoor evacuation routes based on the real-time situation awareness. According to the real-time perception of fire situation parameters and the changing indoor environment information, the evacuation route is optimized dynamically. The integrated representation of multisource indoor fire monitoring sensor observations oriented fire emergency evacuation is presented at first, real-time fire threat situation information inside building is then extracted from the observation data of multi-source sensors, which is used to constrain the dynamical optimization of the topology of the evacuation route. Finally, the simulation experiments prove that this method can improve the accuracy and efficiency of indoor evacuation routing.

    To cope with a large amount of data in current sensed environments, decision aid tools should provide their understanding of situations in a time-efficient manner, so there is an increasing need for real-time network security situation awareness and threat assessment. In this study, the state transition model of vulnerability in the network based on semi-Markov process is proposed at first. Once events are triggered by an attacker's action or system response, the current states of the vulnerabilities are known. Then we calculate the transition probabilities of the vulnerability from the current state to security failure state. Furthermore in order to improve accuracy of our algorithms, we adjust the probabilities that they exploit the vulnerability according to the attacker's skill level. In the light of the preconditions and post-conditions of vulnerabilities in the network, attack graph is built to visualize security situation in real time. Subsequently, we predict attack path, recognize attack intention and estimate the impact through analysis of attack graph. These help administrators to insight into intrusion steps, determine security state and assess threat. Finally testing in a network shows that this method is reasonable and feasible, and can undertake tremendous analysis task to facilitate administrators' work.

    2014-03-01

    The aim of the study was to investigate the influence of different driving scenarios (urban, rural, highway) on the timing required by drivers from a two-stage warning system, based on car-to-car communication. Car-to-car communication systems are designed to inform drivers of potential hazards at an early stage, before they are visible to them. Here, questions arise as to how drivers acknowledge early warnings and when they should be informed (first stage) and warned (second stage). Hence, optimum timing for presenting the information was tested. A psychophysical method was used to establish the optimum timing in three driving scenarios at different speed limits (urban: 50 km/h, rural: 100 km/h, highway: 130 km/h). A total of 24 participants (11 female, 13 male; M = 29.1 years, SD = 11.6 years) participated in the study. The results showed that the optimum timing did not differ among the three scenarios.The first and second stages should ultimately be presented at different timings at each speed limit (first stage: 26.5 s, second stage: 12.1 s before a potential hazard). The results showed that well-selected timing for activating information and warning is crucial for the acceptance of these systems. Appropriate timing for presenting the information and warning can be derived for these systems. The findings will be integrated in further development of assistance systems based on car-to-x technology within the Car2X-Safety project of the Niedersächsisches Forschungszentrum Fahrzeugtechnik in Germany.This study was also supported by Chalmers University of Technology in Sweden.

    The NASA Real Time Mission Monitor (RTMM) is a situational awareness tool that integrates satellite, aircraft state information, airborne and surface instruments, and weather state data in to a single visualization package for real time field experiment management. RTMM optimizes science and logistic decision-making during field experiments by presenting timely data and graphics to the users to improve real time situational awareness of the experiment's assets. The RTMM is proven in the field as it supported program managers, scientists, and aircraft personnel during the NASA African Monsoon Multidisciplinary Analyses (investigated African easterly waves and Tropical Storm Debby and Helene) during August-September 2006 in Cape Verde, the Tropical Composition, Cloud and Climate Coupling experiment during July-August 2007 in Costa Rica, and the Hurricane Aerosonde mission into Hurricane Noel in 2-3 November 2007. The integration and delivery of this information is made possible through data acquisition systems, network communication links, and network server resources built and managed by collaborators at NASA Marshall Space Flight Center (MSFC) and Dryden Flight Research Center (DFRC). RTMM is evolving towards a more flexible and dynamic combination of sensor ingest, network computing, and decision-making activities through the use of a service oriented architecture based on community standards and protocols. Each field experiment presents unique challenges and opportunities for advancing the functionality of RTMM. A description of RTMM, the missions it has supported, and its new features that are under development will be presented.

    Sleep paralysis (SP) entails a period of paralysis upon waking or falling asleep and is often accompanied by terrifying hallucinations. Two situational conditions for sleep paralysis, body position (supine, prone, and left or right lateral decubitus) and timing (beginning, middle, or end of sleep), were investigated in two studies involving 6730 subjects, including 4699 SP experients. A greater number of individuals reported SP in the supine position than all other positions combined. The supine position was also 3-4 times more common during SP than when normally falling asleep. The supine position during SP was reported to be more prevalent at the middle and end of sleep than at the beginning suggesting that the SP episodes at the later times might arise from brief microarousals during REM, possibly induced by apnea. Reported frequency of SP was also greater among those consistently reporting episodes at the beginning and middle of sleep than among those reporting episodes when waking up at the end of sleep. The effects of position and timing of SP on the nature of hallucinations that accompany SP were also examined. Modest effects were found for SP timing, but not body position, and the reported intensity of hallucinations and fear during SP. Thus, body position and timing of SP episodes appear to affect both the incidence and, to a lesser extent, the quality of the SP experience.

    Full Text Available Transforming higher education in South Africa involves, among other things, finding ways of enabling a broader group of students to perform successfully in high-stake assessment. This paper recounts work in progress to that end. The focus is on the effect of time constraints on the performance of physiotherapy students whose first language is other than the one in which the classes and the assessments are presented. The concept of working memory is investigated by using C-tests based on physiotherapy material and the results are correlated with students’ home languages and their performance in other academic subjects. The paper concludes by reflecting on C-tests as a trustworthy instrument to measure situated language proficiency and the implications of the results for higher education.

  19. Assessing qualitative usability in life-threatening, time-critical and unstable situations

    2011-01-01

    Full Text Available We developed a heuristic for assessing the usability of mobile user-interfaces in life-threating, time-critical and unstable situations in a qualitative way. The major advantages of our approach as opposed to standardized quantitative questionnaires is the independence from a baseline, the possibility to make absolute statements and the potential for adaptations. When creating a qualitative semi structured interview we adhere to the common modus operandi of the qualitative social research. On the basis of 17 common quantitative questionnaires on usability we identified the five major categories Utility, Intuitiveness, Memorability, Learnability and Personal Effect. We selected all questions from the questionnaires which are useful for assessing the usability of user-interfaces in emergencies. Furthermore, we rephrased the closed-ended questions to open-ended ones. The quantification of research results is possible by weighting the qualitative results in dependence to the research question.

  20. Framework for Real-Time All-Hazards Global Situational Awareness

    Information systems play a pivotal role in emergency response by making consequence analysis models based on up-to-date data available to decision makers. While consequence analysis models have been used for years on local scales, their application on national and global scales has been constrained by lack of non-proprietary data. This chapter describes how this has changed using a framework for real-time all-hazards situational awareness called the Energy Awareness and Resiliency Standardized Services (EARSS) as an example. EARSS is a system of systems developed to collect non-proprietary data from diverse open content sources to develop a geodatabase of critical infrastructures all over the world. The EARSS system shows that it is feasible to provide global disaster alerts by producing valuable information such as texting messages about detected hazards, emailing reports about affected areas, estimating an expected number of impacted people and their demographic characteristics, identifying critical infrastructures that may be affected, and analyzing potential downstream effects. This information is provided in real-time to federal agencies and subscribers all over the world for decision making in humanitarian assistance and emergency response. The system also uses live streams of power outages, weather, and satellite surveillance data as events unfold. This, in turn, is combined with other public domain or open content information, such as media reports and postings on social networking websites, for complete coverage of the situation as events unfold. Working with up-to-date information from the EARSS system, emergency responders on the ground could pre-position their staff and resources, such as emergency generators and ice, where they are most needed.

  1. Hurry-up and hatch: selective filial cannibalism of slower developing eggs.

    2008-04-23

    Filial cannibalism (the consumption of one's own offspring) is thought to represent an adaptive strategy in many animals. However, little is known about the details of which offspring are consumed when a parent cannibalizes. Here, we examined patterns of within-brood filial cannibalism in the sand goby (Pomatoschistus minutus). Males spawned sequentially with two females, and we asked whether males cannibalized selectively with regard to egg size or the order in which eggs were received. Males preferentially consumed the larger eggs of the second female they spawned with. Because larger eggs took longer to hatch, and because female 2's eggs were up to 1 day behind those of female 1, such preferential cannibalism might allow males to decrease the time spent caring for the current brood and re-enter the mating pool sooner. More work is needed to understand the fitness consequences of such selective cannibalism.

    With the increasing frequency of extreme events due to climate change, wide area situational awareness (SA) of the electric grid has become a primary need for federal agencies like DOE,FEMA etc. for emergency preparedness and recovery purposes. While several sensor feeds from Genscape, GridEye, PMUs provide a comprehensive view of the transmission grid, national-scale situational awareness tools are still relying on utility websites for outage information at a distribution level. The inconsistency and the variety in outage website's data formats makes this approach unreliable and also incurs huge software maintenance costs. Social media has emerged as a great medium for the utilities to share outage information with their customers. Despite their potential usefulness, extracting relevant data from these social media data-streams is challenging due to the inherent noise and irrelevant information such as tips to customers during storms, marketing, etc. In this study, we implement a practical and novel machine learning based data-analytics pipeline (Fig 1) for SA, which extracts real-time tweets from around 300 utility companies, processes these tweets using keyword filtering and Naïve-Bayes text classifier trained using supervised learning techniques to detect only relevant tweets. We validated the results by comparing it with the results identified by a human analyst for a period of 48 hours, and it showed around 98.3% accuracy. In addition to the tweets posted by utility companies, millions of twitter users, who are considered as human "social sensors", report power outages online. Therefore, we use Twitter Streaming API to extract real-time tweets containing keywords such as "power outage", "blackout", and "power cuts". An advanced natural language processing technique is proposed to identify the geo-locations associated with this power outage data. The detected tweets are visualized as a color-coded state and a county US map based on the number of outage tweets

  3. Observer Interface Analysis for Standardization to a Cloud Based Real-Time Space Situational Awareness (SSA)

    The interface analysis from an observer of space objects makes a standard necessary. This standardized dataset serves as input for a cloud based service, which aimed for a near real-time Space Situational Awareness (SSA) system. The system contains all advantages of a cloud based solution, like redundancy, scalability and an easy way to distribute information. For the standard based on the interface analysis of the observer, the information can be separated in three parts. One part is the information about the observer e.g. a ground station. The next part is the information about the sensors that are used by the observer. And the last part is the data from the detected object. Backbone of the SSA System is the cloud based service which includes the consistency check for the observed objects, a database for the objects, the algorithms and analysis as well as the visualization of the results. This paper also provides an approximation of the needed computational power, data storage and a financial approach to deliver this service to a broad community. In this context cloud means, neither the user nor the observer has to think about the infrastructure of the calculation environment. The decision if the IT-infrastructure will be built by a conglomerate of different nations or rented on the marked should be based on an efficiency analysis. Also combinations are possible like starting on a rented cloud and then go to a private cloud owned by the government. One of the advantages of a cloud solution is the scalability. There are about 3000 satellites in space, 900 of them are active, and in total there are about ~17.000 detected space objects orbiting earth. But for the computation it is not a N(active) to N problem it is more N(active) to N(apo peri) quantity of N(all). Instead of 15.3 million possible collisions to calculate a computation of only approx. 2.3 million possible collisions must be done. In general, this Space Situational Awareness System can be used as a

  4. Revising Working Models Across Time: Relationship Situations That Enhance Attachment Security.

    2017-06-01

    We propose the Attachment Security Enhancement Model (ASEM) to suggest how romantic relationships can promote chronic attachment security. One part of the ASEM examines partner responses that protect relationships from the erosive effects of immediate insecurity, but such responses may not necessarily address underlying insecurities in a person's mental models. Therefore, a second part of the ASEM examines relationship situations that foster more secure mental models. Both parts may work in tandem. We posit that attachment anxiety should decline most in situations that foster greater personal confidence and more secure mental models of the self. In contrast, attachment avoidance should decline most in situations that involve positive dependence and foster more secure models of close others. The ASEM integrates research and theory, suggests novel directions for future research, and has practical implications, all of which center on the idea that adult attachment orientations are an emergent property of close relationships.

    The area of Disaster Management is well established among Federal Agencies such as FEMA, EPA, NOAA and NASA. These agencies have well formulated frameworks for response and mitigation based on near real time satellite and conventional observing networks for assimilation into geophysical models. Forecasts from these models are used to communicate with emergency responders and the general public. More recently, agencies have started using social media to broadcast warnings and alerts to potentially affected communities. In this presentation, we demonstrate the added benefits of mining and assimilating the vast amounts of social media data available from heterogeneous hand held devices and social networks into established operational geophysical modeling frameworks as they apply to the five cornerstones of disaster management - Prevention, Mitigation, Preparedness, Response and Recovery. Often, in situations of extreme events, social media provide the earliest notification of adverse extreme events. However, various forms of social media data also can provide useful geolocated and time stamped in situ observations, complementary to directly sensed conventional observations. We use the concept of a Human Sensor Network where one views social media users as carrying field deployed "sensors" whose posts are the remotely "sensed instrument measurements.' These measurements can act as 'station data' providing the resolution and coverage needed for extreme event specific modeling and validation. Here, we explore the use of social media through the use of a Human Sensor Network (HSN) approach as another data input source for assimilation into geophysical models. Employing the HSN paradigm can provide useful feedback in near real-time, but presents software challenges for rapid access, quality filtering and transforming massive social media data into formats consistent with the operational models. As a use case scenario, we demonstrate the value of HSN for disaster management

    2016-09-01

    Space Situational Awareness (SSA) is currently constrained by an overwhelming number of resident space objects (RSOs) that need to be tracked and the amount of data these observations produce. The Joint Centralized Autonomous Tasking System (JCATS) is an autonomous, net-centric tool that approaches these SSA concerns from an agile, information-based stance. Finite set statistics and stochastic optimization are used to maintain an RSO catalog and develop sensor tasking schedules based on operator configured, state information-gain metrics to determine observation priorities. This improves the efficiency of sensors to target objects as awareness changes and new information is needed, not at predefined frequencies solely. A net-centric, service-oriented architecture (SOA) allows for JCATS integration into existing SSA systems. Testing has shown operationally-relevant performance improvements and scalability across multiple types of scenarios and against current sensor tasking tools.

    Full Text Available In Iran Khodro Khorasan, inventory replenishment policy of some items is based on certain simple model (Wilson model. Sometimes because of some reasons, goods reception may not be achieved at the planned time. This state is called as critical situation because the production line is on the eve of stop. The purpose of this paper is to present different inventory replenishment policies in critical situation. For each policy, the cost function that includes cost of line stop, ordering cost, holding cost and transportation cost has been modeled and through its minimization, vehicle type and optimal order quantity have been determined. This model has been used numerically for two items of Iran Khodro Khorasan. Findings show that applying the proposed policy leads to saved cost compared to the current policy of Iran Khodro Khorasan.

    Full Text Available The concept of surgical waiting time initiative (SWAT was introduced in developed countries to reduce elective surgery waiting lists and increase efficiency of care. It was supplemented by increasing popularity of day surgery, which shortens elective waiting lists and minimises cancellations. It is established in Western countries, but not in developing countries like Nigeria where it is still evolving. A search was carried out in Pub Med, Google, African journals online (AJOL, Athens and Ovid for relevant publications on elective surgery waiting list in Nigeria, published in English language. Words include waiting/wait time, waiting time initiative, time to surgery, waiting for operations, waiting for intervention, waiting for procedures and time before surgery in Nigeria.

  11. The analogue method for precipitation prediction: finding better analogue situations at a sub-daily time step

    Horton, Pascal; Obled, Charles; Jaboyedoff, Michel

    Analogue methods (AMs) predict local weather variables (predictands) such as precipitation by means of a statistical relationship with predictors at a synoptic scale. The analogy is generally assessed on gradients of geopotential heights first to sample days with a similar atmospheric circulation. Other predictors such as moisture variables can also be added in a successive level of analogy. The search for candidate situations similar to a given target day is usually undertaken by comparing the state of the atmosphere at fixed hours of the day for both the target day and the candidate analogues. This is a consequence of using standard daily precipitation time series, which are available over longer periods than sub-daily data. However, it is unlikely for the best analogy to occur at the exact same hour for the target and candidate situations. A better analogue situation may be found with a time shift of several hours since a better fit can occur at different times of the day. In order to assess the potential for finding better analogues at a different hour, a moving time window (MTW) has been introduced. The MTW resulted in a better analogy in terms of the atmospheric circulation and showed improved values of the analogy criterion on the entire distribution of the extracted analogue dates. The improvement was found to increase with the analogue rank due to an accumulation of better analogues in the selection. A seasonal effect has also been identified, with larger improvements shown in winter than in summer. This may be attributed to stronger diurnal cycles in summer that favour predictors taken at the same hour for the target and analogue days. The impact of the MTW on the precipitation prediction skill has been assessed by means of a sub-daily precipitation series transformed into moving 24 h totals at 12, 6, and 3 h time steps. The prediction skill was improved by the MTW, as was the reliability of the prediction. Moreover, the improvements were greater for days

    Drivers of automated cars may occasionally need to take back manual control after a period of inattentiveness. At present, it is unknown how long it takes to build up situation awareness of a traffic situation. In this study, 34 participants were presented with animated video clips of traffic situations on a three-lane road, from an egocentric viewpoint on a monitor equipped with eye tracker. Each participant viewed 24 videos of different durations (1, 3, 7, 9, 12, or 20 s). After each video, participants reproduced the end of the video by placing cars in a top-down view, and indicated the relative speeds of the placed cars with respect to the ego-vehicle. Results showed that the longer the video length, the lower the absolute error of the number of placed cars, the lower the total distance error between the placed cars and actual cars, and the lower the geometric difference between the placed cars and the actual cars. These effects appeared to be saturated at video lengths of 7-12 s. The total speed error between placed and actual cars also reduced with video length, but showed no saturation up to 20 s. Glance frequencies to the mirrors decreased with observation time, which is consistent with the notion that participants first estimated the spatial pattern of cars after which they directed their attention to individual cars. In conclusion, observers are able to reproduce the layout of a situation quickly, but the assessment of relative speeds takes 20 s or more.

    The central Texas corridor is one of the most flash flood-prone regions in the United States. Over the years, flash floods have resulted in hundreds of flood fatalities and billions of dollars in property damage. In order to mitigate risk to residents and infrastructure during flood events, both citizens and emergency responders need to exhibit proactive behavior instead of reactive. Real-time and forecasted flood information is fairly limited and hard to come by at varying spatial scales. The University of Texas at Austin has collaborated with IBM Research-Austin and ESRI to build a distributed real-time flood information system through a framework that leverages large scale data management and distribution, Open Geospatial Consortium standardized web services, and smart map applications. Within this paradigm, observed precipitation data encoded in WaterML is ingested into HEC-HMS and then delivered to a high performance hydraulic routing software package developed by IBM that utilizes the latest advancements in VLSI design, numerical linear algebra and numerical integration techniques on contemporary multicore architecture to solve fully dynamic Saint Venant equations at both small and large scales. In this paper we present a real-time flood inundation map application that in conjunction with a web services Hub, seamlessly integrates hydrologic information available through both public and private data services, model services and mapping services. As a case study for this project, we demonstrate how this system has been implemented in the City of Austin, Texas.

    T{sub liquidus} was proposed as the interface temperature, for various severe accident situations for thermalhydraulic steady state. This proposal was made on the basis of the analysis of solidification front stability in thermalhydraulic steady state for volumetrically heated corium pools and was extended to reactor transients with slow solidification rates that are controlled by the long-term decrease in residual power. The conclusions were corroborated by prototypic corium and variable solidification rates obtained by experimental approaches for corium containing small amounts of silica or none at all. When the concentration in silica increases (approximately above 10 wt%), it was concluded from the experiments that a plane-front situation could not be obtained. The present work offers a theoretical approach to the maximum time delay that is necessary for mass transfer and full phase-segregation in volumetrically heated liquid pools bounded by a crust. It is concluded that full segregation is obtained for in-vessel situations within time delays that are shorter or of the same order of magnitude as the characteristic time for the corium pool to form and evolve to a quasi-steady-state situation. The characteristic time delay for mass transfer associated with simulant material experiments is also determined. Phase segregation can also be obtained for corium-concrete interaction, provided that the silica content is less than approximately 10 wt%. However in the latter case, more complex phenomena occur at the interface due to the interaction with sparging gas (such as porous medium formation) which requires a different model approach.

    2017-02-01

    This paper aims to both identify the factors affecting driver drowsiness and to develop a real-time drowsy driving probability model based on virtual Location-Based Services (LBS) data obtained using a driving simulator. A driving simulation experiment was designed and conducted using 32 participant drivers. Collected data included the continuous driving time before detection of drowsiness and virtual LBS data related to temperature, time of day, lane width, average travel speed, driving time in heavy traffic, and driving time on different roadway types. Demographic information, such as nap habit, age, gender, and driving experience was also collected through questionnaires distributed to the participants. An Accelerated Failure Time (AFT) model was developed to estimate the driving time before detection of drowsiness. The results of the AFT model showed driving time before drowsiness was longer during the day than at night, and was longer at lower temperatures. Additionally, drivers who identified as having a nap habit were more vulnerable to drowsiness. Generally, higher average travel speeds were correlated to a higher risk of drowsy driving, as were longer periods of low-speed driving in traffic jam conditions. Considering different road types, drivers felt drowsy more quickly on freeways compared to other facilities. The proposed model provides a better understanding of how driver drowsiness is influenced by different environmental and demographic factors. The model can be used to provide real-time data for the LBS-based drowsy driving warning system, improving past methods based only on a fixed driving. Copyright © 2016 Elsevier Ltd.

    The NASA Short-term Prediction Research and Transition (SPoRT) Center in Huntsville, AL (Jedlovec 2013; Ralph et al. 2013; Merceret et al. 2013) is running a real-time configuration of the Noah land surface model (LSM) within the NASA Land Information System (LIS) framework (hereafter referred to as the "SPoRT-LIS"). Output from the real-time SPoRT-LIS is used for (1) initializing land surface variables for local modeling applications, and (2) displaying in decision support systems for situational awareness and drought monitoring at select NOAA/National Weather Service (NWS) partner offices. The SPoRT-LIS is currently run over a domain covering the southeastern half of the Continental United States (CONUS), with an additional experimental real-time run over the entire CONUS and surrounding portions of southern Canada and northern Mexico. The experimental CONUS run incorporates hourly quantitative precipitation estimation (QPE) from the National Severe Storms Laboratory Multi- Radar Multi-Sensor (MRMS) product (Zhang et al. 2011, 2014), which will be transitioned into operations at the National Centers for Environmental Prediction (NCEP) in Fall 2014. This paper describes the current and experimental SPoRT-LIS configurations, and documents some of the limitations still remaining through the advent of MRMS precipitation analyses in the SPoRT-LIS land surface model (LSM) simulations. Section 2 gives background information on the NASA LIS and describes the realtime SPoRT-LIS configurations being compared. Section 3 presents recent work done to develop a training module on situational awareness applications of real-time SPoRT-LIS output. Comparisons between output from the two SPoRT-LIS runs are shown in Section 4, including a documentation of issues encountered in using the MRMS precipitation dataset. A summary and future work in given in Section 5, followed by acknowledgements and references.

    Emergency responders need access to information but what counts as actionable information depends on their role, task, location, and other variables. For example, experts who have unique knowledge and experience and are called on to serve as scientific and teclmical responders, require correspondingly unique situation awareness in order to do their work. In our research-in-progress we leverage emerging and evolving web and digital library technologies to create personalized situation awareness tools that address the needs of these scientific and technical responders in real time, through focused information collection, extraction, integration, representation, and dissemination. We describe three personalized situation awareness tools in this paper: the Theme Awareness Tool (THEMAT), Social Awareness Tool (SAT), and Expertise Awareness Tool (EXPAT). The concepts and technologies we are developing in collaboration with experts apply to those who use the Web, in general, and offer an approach to the general issue of HCI design for emergencies.

    I show that the curious free recall data of Murdock (1962) can be explained by the Tagging/Retagging model of short term memory (Tarnow, 2009 and 2008) in which a short term memory item is a tagged long term memory item. The tagging (linear in time) corresponds to the synaptic process of exocytosis and the loss of tagging (logarithmic in time) corresponds to synaptic endocytosis. The Murdock recent item recall probabilities follow a logarithmic decay with time of recall. The slope of the d...

    The NASA Short-term Prediction Research and Transition (SPoRT) Center in Huntsville, AL is running a real-time configuration of the Noah land surface model (LSM) within the NASA Land Information System (LIS) framework (hereafter referred to as the "SPoRT-LIS"). Output from the real-time SPoRT-LIS is used for (1) initializing land surface variables for local modeling applications, and (2) displaying in decision support systems for situational awareness and drought monitoring at select NOAA/National Weather Service (NWS) partner offices. The experimental CONUS run incorporates hourly quantitative precipitation estimation (QPE) from the National Severe Storms Laboratory Multi- Radar Multi-Sensor (MRMS) which will be transitioned into operations at the National Centers for Environmental Prediction (NCEP) in Fall 2014.This paper describes the current and experimental SPoRT-LIS configurations, and documents some of the limitations still remaining through the advent of MRMS precipitation analyses in the SPoRT-LIS land surface model (LSM) simulations.

    Full Text Available The article deals with the investigation of theoretical and methodological principles of situational analysis. The necessity of situational analysis is proved in modern conditions. The notion “situational analysis” is determined. We have concluded that situational analysis is a continuous system study which purpose is to identify dangerous situation signs, to evaluate comprehensively such signs influenced by a system of objective and subjective factors, to search for motivated targeted actions used to eliminate adverse effects of the exposure of the system to the situation now and in the future and to develop the managerial actions needed to bring the system back to norm. It is developed a methodological approach to the situational analysis, its goal is substantiated, proved the expediency of diagnostic, evaluative and searching functions in the process of situational analysis. The basic methodological elements of the situational analysis are grounded. The substantiation of the principal methodological elements of system analysis will enable the analyst to develop adaptive methods able to take into account the peculiar features of a unique object which is a situation that has emerged in a complex system, to diagnose such situation and subject it to system and in-depth analysis, to identify risks opportunities, to make timely management decisions as required by a particular period.

    In the fourth century A.H. (tenth century AD) many thinkers, philosophers, jurisprudents, poets, and authors were present in different scientific, literary and health fields in ancient Iran and Islamic world that by their hard attempts the sciences and literature were safe from incidents and resulted in growth, development and innovation of Islamic sciences. Meanwhile, Avicenna was superior to all others and the most famous scientist. He was a great human that by attempting hard, perseverance, stability, patience, and believing in God could complete supreme scientific ranks and compiled encyclopedia of Canon of Medicine and besides gathering many written important issues that most of them were confiscated at libraries of kings. He added medical experiences of ancient Iran and especially Jondishapour University and also his personal experiences and finally Canon of Medicine by benefiting from monotheistic style and science based on faith was written. He has written a book that is regarded as root and basics of modern medicine and by completing it some infrastructure health viewpoints and common medicine were created. It is a kind of book that in spite of scientific advances and production of modern research tools many of its contents are replaced with modern methods of medicine and health, but still many of its health basic messages, research orientation and monotheism with great dynamic mode is considerable at world's medical references. The aim of this study is evaluate the political situation of Avicenna's time and a review of his Godly writings. This is a library study by using electronic version of Canon of Medicine and other related resources. Findings, include writing style of monotheistic literature, and freeing from nihilism and affiliating diseases to Satan, jinn and such issues. It is necessary that our students within course of Iranian and Islamic culture and civilization to be more familiar with monotheistic thoughts and activities of scientists like

    As demonstrated by the March 2011 earthquake and tsunami-triggered blackouts in Japan, electricity shortfalls can happen anytime and anywhere. Countries can minimise the negative economic, social and environmental impacts of such electricity shortfalls by developing emergency energy-saving strategies before a crisis occurs. This new IEA report highlights preliminary findings and conclusions from electricity shortfalls in Japan, the United States, New Zealand, South Africa and Chile. It draws on recent analysis to: reinforce well-established guidelines on diagnosing electricity shortfalls, identifying energy-saving opportunities and selecting a package of energy-saving measures; and highlight proven practice for implementing emergency energy-saving programmes. This paper will be valuable to government, academic, private-sector and civil-society stakeholders who inform, develop and implement electricity policy in general, and emergency energy-saving programmes in particular.

  9. Situating Emotional Experience

    Directory of Open Access Journals (Sweden)

    Christine D Wilson-Mendenhall

    2013-11-01

    Full Text Available Psychological construction approaches to emotion suggest that emotional experience is situated and dynamic. Fear, for example, is typically studied in a physical danger context (e.g., threatening snake, but in the real world, it often occurs in social contexts, especially those involving social evaluation (e.g., public speaking. Understanding situated emotional experience is critical because adaptive responding is guided by situational context (e.g., inferring the intention of another in a social evaluation situation vs. monitoring the environment in a physical danger situation. In an fMRI study, we assessed situated emotional experience using a newly developed paradigm in which participants vividly imagine different scenarios from a first-person perspective, in this case scenarios involving either social evaluation or physical danger. We hypothesized that distributed neural patterns would underlie immersion in social evaluation and physical danger situations, with shared activity patterns across both situations in multimodal sensory regions and in circuitry involved in integrating salient sensory information, and with unique activity patterns for each situation type in coordinated large-scale networks that reflect situated responding. More specifically, we predicted that networks underlying the social inference and mentalizing involved in responding to a social threat (in regions that make up the default mode network would be reliably more active during social evaluation situations. In contrast, networks underlying the visuospatial attention and action planning involved in responding to a physical threat would be reliably more active during physical danger situations. The results supported these hypotheses. In line with emerging psychological construction approaches, the findings suggest that coordinated brain networks offer a systematic way to interpret the distributed patterns that underlie the diverse situational contexts characterizing

    Most attempts of deterministic eruption forecasting are based on the material Failure Forecast Method (FFM). This method assumes that a precursory observable, such as the rate of seismic activity, can be described by a simple power law which presents a singularity at a time close to the eruption onset. Until now, this method has been applied only in a small number of cases, generally for forecasts in hindsight. In this paper, a rigorous Bayesian approach of the FFM designed for real-time applications is applied. Using an automatic recognition system, seismo-volcanic events are detected and classified according to their physical mechanism and time series of probability distributions of the rates of events are calculated. At each time of observation, a Bayesian inversion provides estimations of the exponent of the power law and of the time of eruption, together with their probability density functions. Two criteria are defined in order to evaluate the quality and reliability of the forecasts. Our automated procedure has allowed the analysis of long, continuous seismic time series: 13 years from Volcán de Colima, Mexico, 10 years from Piton de la Fournaise, Reunion Island, France, and several months from Merapi volcano, Java, Indonesia. The new forecasting approach has been applied to 64 pre-eruptive sequences which present various types of dominant seismic activity (volcano-tectonic or long-period events) and patterns of seismicity with different level of complexity. This has allowed us to test the FFM assumptions, to determine in which conditions the method can be applied, and to quantify the success rate of the forecasts. 62% of the precursory sequences analysed are suitable for the application of FFM and half of the total number of eruptions are successfully forecast in hindsight. In real-time, the method allows for the successful forecast of 36% of all the eruptions considered. Nevertheless, real-time forecasts are successful for 83% of the cases that fulfil the

    2011-01-01

    Text comprehension is a process that people construct mental representation of the information the text described. The mechanism of text comprehension has always been a hot issue for cognitive psychologists. Recently, in the study of text comprehension, the mechanism of situation model processing has been focused on. Situation model, the deep-seated mental representation during reader's reading comprehension, includes five dimensions: temporality, spatiality, causality, intentionality, and protagonist. Most psychological experts have agreed that the construction and processing of situational model result from the interaction of the five dimensions.Although the protagonist's emotions play a very important role in the construction and processing of situational model, there are only a few experimental studies on it so far. Therefore the primary purpose of this study is to explore the mechanism of the protagonist's emotion in the processing of situation model. Former research on the temporality dimension has mainly focused on the representation of temporal shift or temporal distance from a single dimension. Actually, construction and update of the situation model are influenced by multiple dimensions. So the second purpose of this study is to combine the factors of protagonist's emotions with temporal shift, so as to explore the effect of protagonist's emotions and time information representation onthe situation model process.A hundred and twenty college students have participated in this study, forty in experiment group 1, and eighty in experiment group 2. Through moving window and recording the reading time of the critical sentence, experiment 1 was designed to explore the functions of protagonist's emotions, experiment 2 to explore the functions of protagonist's emotions and temporal shift on situation model processing. Using E-Prime software on Legend Computer, experiment 1 is single-factor within-subjects design, experiment 2 is 4 x 2 within-subjects design. The

    Ritchie, Jason; Basevitch, Itay; Rodenberg, Ryan; Tenenbaum, Gershon

    2017-11-01

    Officials are expected to perform impeccably despite the wide range of stressors they experience. A stressor that officials frequently report is situation criticality. Situation criticality is comprised of score differential (i.e., more pressure in close games) and time remaining in a game (i.e., more pressure as time expires), which affects athletes' stress levels. The present study explored the effect of situation criticality on officials' stress levels. High school basketball officials (n = 108) with an average of 18.1 (SD = 11.2) years of officiating experience were given a survey packet containing game situations that varied in criticality. For each game situation (n = 9) officials completed the overall stress and appraisal portions of the Stress Appraisal Measure (SAM). Results revealed that situation criticality has an effect on officials' perceived stress levels. Both threat and challenge appraisals were positively correlated with perceived stress. Overall, these findings indicate that officials' stress levels fluctuate within games depending on score differential and time of game. The findings encourage officials to recognise and manage their stress, possibly through their appraisals. Additionally, the findings can affect the training of officials in the management of stress, as well as prompt the consideration of potential rule changes that reflect the increased situational demands on officials in critical situations (e.g., expanded instant replay).

    Waller, D J; Smith, S R; Warnock, J T

    1989-11-01

    The situational theory of leadership and the LEAD instruments for determining leadership style are explained, and the application of the situational leadership theory to the process of planning for and implementing organizational change is described. Early studies of leadership style identified two basic leadership styles: the task-oriented autocratic style and the relationship-oriented democratic style. Subsequent research found that most leaders exhibited one of four combinations of task and relationship behaviors. The situational leadership theory holds that the difference between the effectiveness and ineffectiveness of the four leadership styles is the appropriateness of the leader's behavior to the particular situation in which it is used. The task maturity of the individual or group being led must also be accounted for; follower readiness is defined in terms of the capacity to set high but attainable goals, willingness or ability to accept responsibility, and possession of the necessary education or experience for a specific task. A person's leadership style, range, and adaptability can be determined from the LEADSelf and LEADOther questionnaires. By applying the principles of the situational leadership theory and adapting their managerial styles to specific tasks and levels of follower maturity, the authors were successful in implementing 24-hour pharmacokinetic dosing services provided by staff pharmacists with little previous experience in clinical services. The situational leadership model enables a leader to identify a task, set goals, determine the task maturity of the individual or group, select an appropriate leadership style, and modify the style as change occurs. Pharmacy managers can use this model when implementing clinical pharmacy services.

    Mallia, Pierre

    2015-02-01

    Health Care professionals working in disaster situations have to face urgent choices which diverge from their normal deontological ethos and are more utilitarian. Such is the triage system used to choose whom to treat. Instead of entering a crisis these professionals should be thought that ethics is not harmonizable to all situations and that there are situations in which saving as many lives as possible mean sacrificing others. This calls for defining a perimeter zone in which such choices occur, and a time frame (a space-time niche) in which it ought to be considered ethical and legitimate to use such value laden choices.

    The features characterizing study of clinical cognition in situ are formulated as: Re-cognition of context, culture, history and affect. Socializing and phenomenalistic elements are again included in the research agenda. Interest for representations: an analysis level is reserved for the symbols, rules and images relevant to define in models of clinical cognition. De-emphasis on computer modeling: investigations focus on the 'functional systems' in which computers are involved. Rootedness in classical philosophical problems: issues concerning situated clinical cognition are connected to the width of available theoretical literature. Belief in interdisciplinary studies: productive interactions between the new and traditional disciplines is anticipated, implying that new shared methods have to be developed. When scientific perspectives are broadened, a new balance has to be found between the relevance of the subject of study and methodological rigor. The situated clinical cognition framework is to allow for moving between models, theories, and perspectives, as it does not presuppose a singular model of clinical thinking.

    The international energy situation has entered a new phase of change and readjustment. On the one hand, while imbalances in petroleum market supply-demand have been alleviated , the consuming states are now focusing on demand side management and development of new and renewable energy. There has been great progress in international energy security dialogue and cooperation. On the other hand , supply-demand market balance remains fragile , and restrictions due to insufficient energy investment are more evident. The concerned states have taken a stronger grip over their own resources. Implementation of energy diplomacy has also further complicated the relationship between energy and geo-politics, causing an upsurge of competition.

    Full Text Available Violence comes in many forms and occurs in many different circumstances for many different reasons. Is it really possible to develop a single theory that can explain all these disparate acts? In this paper, we argue it is. We make the case that acts of violence are essentially moral actions and therefore can, and should, be analysed and explained as such. We maintain that all acts of violence can be explained within the general framework of a theory of moral action. We present just such a theory – Situational Action Theory – and demonstrate how it can be applied to the explanation and study of violence.

For this reason, ESO has until now been silent in these matters, but we have now become obliged to make our opinion known". The ESO representative also made it clear, that "ESO does not question the rights of the claimants to recur to the Chilean Tribunals which must decide on the matter of ownership, and that ESO cannot be party to this lawsuit". He added that "ESO fully trusts that the Chilean Government will do whatever is necessary to defend the immunity of ESO". THE CURRENT SITUATION During the past few days, declarations from high officials at the Chilean Ministry of Foreign Affairs have been made which clearly confirm ESO's immunity of jurisdiction from Chilean Courts. The same opinion has been ventured by Chilean experts in international law, quoted in various Chilean newspapers. On Friday, February 17, the Chilean Minister of Foreign Affairs, Mr. Jose M. Insulza, made a similar, very eloquent statement. ESO welcomes these articulate expressions that support its official position and trusts that the current situation will be speedily resolved by the competent Chilean authorities, so that the construction work at Paranal will not be stopped. During the past three decades, ESO's presence in Chile has been characterised by good relations to all sides. The development of astronomy in Chile during the past decades has reached such a level that it will now benefit from a new quality of cooperation. In addition to its past and numerous services to Chilean astronomy, ESO has recently considered to establish a "guaranteed" observing time for astronomers from this country, both at La Silla and the future VLT observatory on Paranal. With a proposed 10 percent quota for the VLT, Chilean astronomers will in fact have free access to the equivalent of 40 percent of one 8.2-metre telescope; the associated, not insignificant cost is entirely carried by ESO. ESO has also considered to incorporate

  11. Putting judging situations into situational judgment tests: evidence from intercultural multimedia SJTs.

    2015-03-01

    Although the term situational judgment test (SJT) implies judging situations, existing SJTs focus more on judging the effectiveness of different response options (i.e., response judgment) and less on how people perceive and interpret situations (i.e., situational judgment). We expand the traditional SJT paradigm and propose that adding explicit assessments of situational judgment to SJTs will provide incremental information beyond that provided by response judgment. We test this hypothesis across 4 studies using intercultural multimedia SJTs. Study 1 uses verbal protocol analysis to discover the situational judgments people make when responding to SJT items. Study 2 shows situational judgment predicts time-lagged, peer-rated task performance and interpersonal citizenship among undergraduate seniors over and above response judgment and other established predictors. Study 3 shows providing situational judgment did not affect the predictive validity of response judgment. Study 4 replicates Study 2 in a working adult sample. We discuss implications for SJT theory as well as the practical implications of putting judging situations back into SJTs.

  16. Sizing Up the Situation

    Science.gov (United States)

    2004-01-01

    Hailstorm damage to the Space Shuttle's External Tank inspired a NASA innovation with extensive photography applications. In order to measure the defects caused by the storm, Kennedy Space Center used telephoto lenses to zoom in on the tank and view the damage clearly. However, since there was no reference object in the image, the engineers could not determine the scale of the damage. In photographic situations similar to this, an object, such as a ruler, is placed within the field of view. This allows a person to look at a photograph and have a visual indication of the scale of the objects in it. In the External Tank situation, however, this procedure was not possible. As a solution, Kennedy developed the Scaling and Measurement Device for Photographic Images, which provides a non-intrusive means of adding a scale to a photograph. In addition to meeting Kennedy's needs, scaling images is extremely important in crime and accident scene investigations, oil and chemical tank monitoring, and aerial photography. The innovation consists of a tool that attaches directly to a camera or charge coupled device using a standard screw. Two lasers fitted to the device provide parallel beams that are set 1 inch apart. These lasers enable the device to project a pattern into the field of view. When a photograph is taken, the image of the laser pattern appears, along with the image of the object under investigation, allowing the viewer quantifiable information as to the size of the object. The laser beams are accurate to approximately 200 feet. Windows-based software was developed to work with the scaling device tool. The software provides further techniques to measure objects in photographs and digital images. By using the software, any object in the image can be measured diagonally, vertically, and horizontally. The device and its software enable the user to determine two-dimensional measurements within a photograph.

  17. An Event Based Approach To Situational Representation

    CERN Document Server

    Ashish, Naveen; Mehrotra, Sharad; Venkatasubramanian, Nalini

    2009-01-01

    Many application domains require representing interrelated real-world activities and/or evolving physical phenomena. In the crisis response domain, for instance, one may be interested in representing the state of the unfolding crisis (e.g., forest fire), the progress of the response activities such as evacuation and traffic control, and the state of the crisis site(s). Such a situation representation can then be used to support a multitude of applications including situation monitoring, analysis, and planning. In this paper, we make a case for an event based representation of situations where events are defined to be domain-specific significant occurrences in space and time. We argue that events offer a unifying and powerful abstraction to building situational awareness applications. We identify challenges in building an Event Management System (EMS) for which traditional data and knowledge management systems prove to be limited and suggest possible directions and technologies to address the challenges.

    Based on accumulating evidence, simulation appears to be a basic computational mechanism in the brain that supports a broad spectrum of processes from perception to social cognition. Further evidence suggests that simulation is typically situated, with the situated character of experience in the environment being reflected in the situated character of the representations that underlie simulation. A basic architecture is sketched of how the brain implements situated simulation. Within this framework, simulators implement the concepts that underlie knowledge, and situated conceptualizations capture patterns of multi-modal simulation associated with frequently experienced situations. A pattern completion inference mechanism uses current perception to activate situated conceptualizations that produce predictions via simulations on relevant modalities. Empirical findings from perception, action, working memory, conceptual processing, language and social cognition illustrate how this framework produces the extensive prediction that characterizes natural intelligence.

    Almost three years ago, on May 6, 2005, the Spanish government published in its official register, the Boletin Oficial de Estado, a decree on Nursing Specialities. This law is one which answers one of the historical Spanish nursing profession complaints. Its development will radically change the structure of the Spanish health system. An event which bears such consequences requires certain steps and a serene undertaking for those steps which will become the fundamental bases for each of them. Nonetheless, for professionals who greeted the passage of this decree with pleasure and illusion, this whole process has been one long wait. Now is the time to analyze the different specialities and to know the developmental situation of each one. The overall balance is seen in a very positive light.

    Full Text Available In this paper we analyzed the cirumstances of every day life which requires the need to adapt the leadership style. Leadership needs a lot of abilities and skills, including the capability to communicate. The paper deals with leader’s need of changing the style of leading as organizational circumstances change. The process is efficient only when the leaders and the followers have the right climate. The importance of this process is reflected in the productivity of the organization. As the economic climate changes the leadership style needs to be changed and also the style of communication throughout the leader coaches, coordinates, evaluates and supervises. Leadership is about organizing a group of people to achieve a goal. The leader may or may not have any formal authority. Students of leadership have produced theories involving traits, situational interaction, function, behavior, power, vision and values, charisma, and intelligence, among others. This paper describes the styles of leadership which the leaders must use and switch when is needed in comparison with what leadership is about.

  3. Constructing catalogue of temporal situations

    2015-11-01

    Full Text Available Constructing catalogue of temporal situations The paper is aiming to create a common basis for description, comparing, and analysis natural languages. As a subject of comparison we have chosen temporal structures of some languages. For such a choice there exists a perfect tool, describing basic temporal phenomena, namely an ordering of states and events in time, certainty and uncertainty, independency of histories of separate objects, necessity and possibility. This tool is supported by the Petri nets formalism, which seems to be well suited for expressing the above mentioned phenomena. Petri nets are built form three primitive notions: of states, of events that begin or end the states, and so-called flow relation indicating succession of states and events. This simple constituents give rise to many possibilities of representing temporal phenomena; it turns out that such representations are sufficient for many (clearly, not necessarily all temporal situations appearing in natural languages. In description formalisms used till now there is no possibility of expressing such reality phenomena as temporal dependencies in compound statement, or combination of temporality and modality. Moreover, using these formalisms one cannot distinguish between two different sources of uncertainty of the speaker while describing the reality: one, due to the lack of knowledge of the speaker what is going on in outside world, the second, due to objective impossibility of foreseen ways in which some conflict situations will be (or already have been resolved. Petri net formalism seems to be perfectly suited for such differentiations. There are two main description principles that encompassed this paper. First, that assigns meaning to names of grammatical structures in different languages may lead to misunderstanding. Two grammatical structures with apparently close names may describe different reality. Additionally, some grammatical terms used in one language may be

  4. Preparing for Emergency Situations

    Asproth, Viveca; Amcoff Nyström, Christina

    2010-11-01

    Disaster relief can be seen as a dynamic multi actor process with actors both joining and leaving the relief work during the help and rescue phase after the disaster has occurred. Actors may be governmental agencies, non profit voluntary organisations or spontaneous helpers comprised of individual citizens or temporal groups of citizens. Hence, they will vary widely in agility, competence, resources, and endurance. To prepare for for disasters a net based Agora with simulation of emergency situations for mutual preparation, training, and organisational learning is suggested. Such an Agora will ensure future security by: -Rising awareness and preparedness of potential disaster responders by help of the components and resources in the netAgora environment; -Improving cooperation and coordination between responders; -Improving competence and performance of organisations involved in security issues; -Bridging cultural differences between responders from different organizations and different backgrounds. The developed models are intended to reflect intelligent anticipatory systems for human operator anticipation of future consequences. As a way to catch what should be included in this netbased Agora and to join the split pictures that is present, Team Syntegrity could be a helpful tool. The purpose of Team Syntegrity is to stimulate collaboration and incite cross fertilization and creativity. The difference between syntegration and other group work is that the participants are evenly and uniquely distributed and will collectively have the means, the knowledge, the experience, the perspectives, and the expertise, to deal with the topic. In this paper the possibilities with using Team Syntegrity in preparation for the development of a netbased Agora is discussed. We have identified that Team Syntegrity could be useful in the steps User Integration, Designing the netAgora environment, developing Test Scenarios, and assessment of netAgora environment.

    The nuclear activities are exercised so as to prevent the accidents. They are subjected to a rule whom application is controlled by the Asn. The risk of grave accident is so limited to a very low level of probability. He cannot be however completely pushed aside. The expression ' radiological emergency situation ' indicates a situation which ensues from an incident or of an accident risking to lead to an emission of radioactive materials or a level of radioactivity susceptible to strike a blow at the public health. The term ' nuclear crisis ' is used for the events which can lead to a radiological emergency situation on a nuclear basic installation or during a transport of radioactive materials. The preparation and the management of emergency situations, that they are of natural, accidental or terrorist origin, became a major concern of our society.

    Jones, Kennie H.; Lodding, Kenneth N.; Olariu, Stephan; Wilson, Larry; Xin, Chunsheng

    2006-01-01

    Situation Management is a rapidly developing science combining new techniques for data collection with advanced methods of data fusion to facilitate the process leading to correct decisions prescribing action. Current research focuses on reducing increasing amounts of diverse data to knowledge used by decision makers and on reducing time between observations, decisions and actions. No new technology is more promising for increasing the diversity and fidelity of observations than sensor networks. However, current research on sensor networks concentrates on a centralized network architecture. We believe this trend will not realize the full potential of situation management. We propose a new architecture modeled after biological ecosystems where motes are autonomous and intelligent, yet cooperate with local neighborhoods. Providing a layered approach, they sense and act independently when possible, and cooperate with neighborhoods when necessary. The combination of their local actions results in global effects. While situation management research is currently dominated by military applications, advances envisioned for industrial and business applications have similar requirements. NASA has requirements for intelligent and autonomous systems in future missions that can benefit from advances in situation management. We describe requirements for the Integrated Vehicle Health Management program where our biology-inspired architecture provides a layered approach and decisions can be made at the proper level to improve safety, reduce costs, and improve efficiency in making diagnostic and prognostic assessments of the structural integrity, aerodynamic characteristics, and operation of aircraft.

    Department of Defense, has been integrating data from diverse sources for decades. In recent years, more and more commercial entities have been integrating our data into their operations, whether to use General Perturbation (GP) Two-Line Elements (TLEs) to perform a rudimentary form of conjunction assessment (CA) or to provide a new app for the iPhone. For the longest time, the USG was one of the few organizations able to fund and conduct space surveillance using optical telescopes and various types of radar. Unfortunately, despite decades of experience tracking objects in space, we had not matured either our equipment or our processes to the point that we were able to prevent the Iridium-Cosmos collision about 18 months ago. As a result, there are two belts of debris orbiting our planet, today and for years to come. As space has become more congested and budgets have shrunk, the need to integrate data has increased. Fortunately, the number of organizations who have developed or are developing space situational awareness (SSA) capabilities, including analytical tools, has also increased.

  7. Cyber situation awareness and teamwork

    Directory of Open Access Journals (Sweden)

    Nancy J. Cooke

    2013-05-01

    Full Text Available Cyber analysis is a complex task that requires the coordination of a large sociotechnical system of human analysts working together with technology. Adequate situation awareness of such a complex system requires more than aggregate situation awareness of individuals. Teamwork in the form of communication and information coordination is at the heart of team-level situation awareness. In this position paper, we report observations from previously conducted cognitive task analyses that suggest that teamwork is lacking in many cyber analysis organizations. Communication is ineffective, team roles are inconsistent across organizations, reward structures and selection may thwart collaboration, and the environment is conducive to individual work. Suggestions for improving teamwork in the cyber domain are offered.

  14. Reducing client waiting time.

    Science.gov (United States)

    1992-01-01

    This first issues of Family Planning (FP) Manager focuses on how to analyze client waiting time and reduce long waits easily and inexpensively. Client flow analysis can be used by managers and staff to identify organizational factors affecting waiting time. Symptoms of long waiting times are overcrowded waiting rooms, clients not returning for services, staff complaints about rushing and waiting, and hurried counseling sessions. Client satisfaction is very important in order to retain FP users. Simple procedures such as routing return visits differently can make a difference in program effectiveness. Assessment of the number of first visits, the number of revisits, and types of methods and services that the clinic provides is a first step. Client flow analysis involves assigning a number to each client on registration, attaching the client flow form to the medical chart, entering the FP method and type of visit, asking staff to note the time at each station, and summarizing data in a master chart. The staff should be involved in plotting data for each client to show waiting versus staff contact time through the use of color coding for each type of staff contact. Bottlenecks become very visible when charted. The amount of time spent at each station can be measured, and gaps in client's contact with staff can be identified. An accurate measure of total waiting time can be obtained. A quick assessment can be made by recording arrival and departure times for each client in one morning or afternoon of a peak day. The procedure is to count the number of clients waiting at 15-minute intervals. The process should be repeated every 3-6 months to observe changes. If waiting times appear long, a more thorough assessment is needed on both a peak and a typical day. An example is given of a completed chart and graph of results with sample data. Managers need to set goals for client flow, streamline client routes, and utilize waiting time wisely by providing educational talks

    2017-05-01

    Recent advances in big data (BD) have focused research on the volume, velocity, veracity, and variety of data. These developments enable new opportunities in information management, visualization, machine learning, and information fusion that have potential implications for space situational awareness (SSA). In this paper, we explore some of these BD trends as applicable for SSA towards enhancing the space operating picture. The BD developments could increase in measures of performance and measures of effectiveness for future management of the space environment. The global SSA influences include resident space object (RSO) tracking and characterization, cyber protection, remote sensing, and information management. The local satellite awareness can benefit from space weather, health monitoring, and spectrum management for situation space understanding. One area in big data of importance to SSA is value - getting the correct data/information at the right time, which corresponds to SSA visualization for the operator. A SSA big data example is presented supporting disaster relief for space situation awareness, assessment, and understanding.

    The analysis of communicative intents is described as it has developed over time, beginning with J.L. Austin's work published in 1975. Recommendations for best practice are offered in which a situated approach is advocated. Key elements of this approach are a focus on contextual variables and open-ended, rather than list-oriented, assessments of range of intents. It is argued that intents must be assessed relative to the environment, with documentation of environmental variables such as barriers to communicative opportunity. Further, caution is urged in using lists of intents as the sole guide to analysis, because such lists serve to limit awareness of individual differences and multifunctionality of utterances.

    Propose a new sensor-based motion planning approach of Situated-Bug, which is composed of goal-oriented behavior, boundary following behavior and goal-oriented obstacle avoidance behavior, which are based on fuzzy control. The situated-Bug selects its behaviors according to robot orientation, instead of positions and hit points like other Bug algorithms, and its convergence proves robust to sensor noise, and it can guide the robots running for long rang traverse. At the same time, the design of the Situated-Bug is presented. Simulation results show that the approach is effective and practical.

    The Data and Information Fusion domains have for some time addressed the issues involved with Situation Estimation and Situation Refinement as part of the characterization of the "higher" levels of fusion processing, meaning those levels of processing that deal with more abstract and complex world states of interest that people call "situations". It is usually agreed however that at the moment at least the research in the Data and Information Fusion (DIF) field has by far been on the aspects of estimating single and sometimes multiple-object attributes from composite observational data, and usually from electronic or physics-based sensing devices such as radars and imaging systems, that is, on the so-called "lower" levels of fusion. As both the world and the technology have changed, and as research in the DIF arena has matured, there has been a considerable interest in directing the research to methods for estimating the higher state levels of DIF, usually called Situation Refinement and Threat or Impact Refinement, and related to "Level 2" and "Level 3" of the well-known "JDL" DIF process Model (Ref 1). Note that the "refinement" term is important, implying an awareness of the fact that the focus of DIF processing is almost always on dynamic events in the world; it also reflects the need for a temporally-adaptive, recursive state estimation process.

  15. Representing Operational Modes for Situation Awareness

    Operating complex plants is an increasingly demanding task for human operators. Diagnosis of and reaction to on-line events requires the interpretation of real time data. Vast amounts of sensor data as well as operational knowledge about the state and design of the plant are necessary to deduct reasonable reactions to abnormal situations. Intelligent computational support tools can make the operator’s task easier, but they require knowledge about the overall system in form of some model. While tools used for fault-tolerant control design based on physical principles and relations are valuable tools for designing robust systems, the models become too complex when considering the interactions on a plant-wide level. The alarm systems meant to support human operators in the diagnosis of the plant-wide situation on the other hand fail regularly in situations where these interactions of systems lead to many related alarms overloading the operator with alarm floods. Functional modelling can provide a middle way to reduce the complexity of plant-wide models by abstracting from physical details to more general functions and behaviours. Based on functional models the propagation of failures through the interconnected systems can be inferred and alarm floods can potentially be reduced to their root-cause. However, the desired behaviour of a complex system changes due to operating procedures that require more than one physical and functional configuration. In this paper a consistent representation of possible configurations is deduced from the analysis of an exemplary start-up procedure by functional models. The proposed interpretation of the modelling concepts simplifies the functional modelling of distinct modes. The analysis further reveals relevant links between the quantitative sensor data and the qualitative perspective of the diagnostics tool based on functional models. This will form the basis for the ongoing development of a novel real-time diagnostics system based

  16. Investigating Situational Interest in Primary Science Lessons

    Pupils' interest has been one of the major concerns in science education research because it can be seen as a gateway to more personalised forms of interest and motivation. However, methods to investigate situational interest in science teaching and learning are not broadly examined. This study compares the pupils' observed situational interest and their expressed situational interest. One class of Finnish fourth-graders (N = 22, age 9-10 years) participated in a heat transfer lesson. The lesson encompassed an interactive demonstration with a thermal camera, teacher-led discussions and the conduct and presentation of a collaborative inquiry task. Pupils expressed their interest levels (scale: 1 = very boring, 5 = very interesting) by using an electronic response system called a 'clicker'. The measurement took place 15 times during the lesson, with 1 measurement being just a rehearsal. The lesson was video recorded, and visible aspects of interest at the measurement time points were analysed. Reported and observational data were compared. In most cases, the observations did not yield data compatible with the pupils' own evaluations, indicating that most pupils' expressed interest is not easily interpreted through observation of their facial expressions and behaviour. In general, the interest of the group as a whole seems to diminish during the lesson. We argue that in order to maintain and increase pupils' interest, their evaluations should be taken into account in lesson planning. Video-based research might also be further enriched and validated by employing the participants' own expressions. The clicker is a suitable means of collecting primary pupils' experiences concerning their interest levels.

  18. A concept analysis of situational awareness in nursing.

    2013-12-01

    This article reports an analysis of the concept of situational awareness in nursing. Situational awareness is a fundamental and well-understood concept used to maintain operational safety in high reliability organizations; however, it has not been studied in nursing. Nurses play a critical role in providing vigilance in health care and what they do or fail to do is directly related to patient outcomes. Multiple databases, including PubMed, CINAHL, JSTOR, and Google Scholar, were searched with the term, 'situational awareness'. The primary search, used to identify all uses of the concept, did not employ date criteria. A secondary search for articles measuring situational awareness as an independent or dependent variable was completed using 2009-2011 articles. Concept Analysis. The concept of situational awareness was examined using Walker and Avant's eight step method of analysis. Three defining attributes of situational awareness include perception, comprehension, and projection. Situational awareness is defined as the perception of the elements in the environment in a volume of time and space, the comprehension of their meaning and the projection of their status in the near future. Although situational awareness is related to other terms in nursing, there is increasing recognition that the concept, which is likely a consolidation of the related terms, has an impact on healthcare professionals. Failures in perception, comprehension, and/or projection can significantly reduce the accuracy and appropriateness of patient care decisions. Therefore, as a precursor to decision making, poor or inadequate levels of situational awareness present serious threats to patient safety. Situational awareness needs to be examined in a theoretical context, studied systematically and openly recognized as a key factor in the delivery of safe patient care. © 2013 John Wiley & Sons Ltd.

  19. Situational Strength Cues from Social Sources at Work: Relative Importance and Mediated Effects

    Full Text Available Situational strength is considered one of the most important situational forces at work because it can attenuate the personality–performance relationship. Although organizational scholars have studied the consequences of situational strength, they have paid little attention to its antecedents. To address this gap, the current study focused on situational strength cues from different social sources as antecedents of overall situational strength at work. Specifically, we examined how employees combine situational strength cues emanating from three social sources (i.e., coworkers, the immediate supervisor, and top management. Based on field theory, we hypothesized that the effect of situational strength from coworkers and immediate supervisors (i.e., proximal sources of situational strength on employees' perceptions of overall situational strength on the job would be greater than the effect of situational strength from the top management (i.e., the distal source of situational strength. We also hypothesized that the effect of situational strength from the distal source would be mediated by the effects of situational strength from the proximal sources. Data from 363 full-time employees were collected at two time points with a cross-lagged panel design. The former hypothesis was supported for one of the two situational strength facets studied. The latter hypothesis was fully supported.

    Geographically, Turkey is situated in an area where malaria is very risky. The climatic conditions in the region are suitable for the malaria vector to proliferate. Due to agricultural infrastructural changes, GAP and other similar projects, insufficient environmental conditions, urbanization, national and international population moves, are a key to manage malaria control activities. It is estimated that malaria will be a potential danger for Turkey in the forthcoming years. The disease is located largely in south-eastern Anatolia. The Diyarbakir, Batman, Sanliurfa, Siirt, and Mardin districts are the most affected areas. In western districts, like Aydin and Manisa, an increase in the number of indigenous cases can be observed from time to time. This is due to workers moving from malaria districts to western parts to final work. Since these workers cannot be controlled, the population living in these regions get infected from indigenous cases. There were 84,345 malaria cases in 1994 and 82,096 in 1995, they decreased to 60,884 in 1996 and numbered 35,456 in 1997. They accounted for 36,842 and 20,963 in 1998 and 1999, respectively. In Turkey there are almost all cases of P. vivax malaria. There are also P. vivax and P. falciparum malaria cases coming from other countries: There were 321 P. vivax cases, including 2 P. falciparum ones, arriving to Turkey from Iraq in 1995. The P. vivax malaria cases accounted for 229 in 1996, and 67, cases P. vivax including 12 P. falciparum cases, in 1997, and 4 P. vivax cases in 1998 that came from that country. One P. vivax case entered Turkey from Georgia in 1998. The cause of higher incidence of P. vivax cases in 1995, it decreasing in 1999, is the lack of border controls over workers coming to Turkey. The other internationally imported cases are from Syria, Sudan, Pakistan, Afghanistan, Nigeria, India, Azerbaijan, Malaysia, Ghana, Indonesia, Yemen. Our examinations have shown that none of these internationally imported cases

    Recently, there has been a great deal of interest in what has been called 'situated cognition', which has included claims that certain forms of representation are inadequate for modeling active organisms or agents such as humans and robots. In this article, I suggest that a weakness in classical theories of visual representation is the way in which representations connect with the real world, which may account for many of the concerns expressed by the situated cognition community. Specifically, I claim that what current theories lack is any provision for a certain form of direct, preconceptual connection between objects in the visual world (visual objects or proto-objects) and their representations in the visual system. This type of connection is akin to what philosophers and semanticists have referred to as an 'indexical' or 'demonstrative' reference and what some cognitive scientists have referred to as 'deictic pointers'. I explain why such a mechanism is needed and suggest that many workers have, in fact, been studying precisely this under the term 'visual index'. The visual index hypothesis is illustrated with the results of some relevant experiments, including multiple object tracking, visual routines and subset-selected visual searches. Indexing theory provides a synthesis that has profound implications for explaining a wide range of psychophysical findings, certain results in infant cognitive development and also some ancient problems in the philosophy of mind.

    With the rapid development of aerospace and remote sensing technology, various high-resolution Earth Observation Systems (EOS) are widely used in economic, social, military and other fields and playing an increasingly prominent role in the construction of Digital Earth and national strategic planning. The normal operation of the system is the premise of high quality data acquisition. Compared with the ground observation mode, EOS itself and the surrounding environment are more complex, and its operation control mainly depends on all kinds of Space Situational Awareness (SSA) data acquisition and analysis. SSA data has more extensive sources, larger volume, stronger time-effectiveness and more complicated structure than traditional geographical spatial data. For effective data sharing and utilization, combined with the analysis of data types and structures, a SSA data sharing identity language SSDSML is designed based on the extensible mark-up language XML, which realizes a comprehensive description of satellites and their attributes, space environment, ground stations, etc. Then EOS situational data shared service mechanism is established and provides a powerful data support for the normal operation of the system.

    This paper addresses the problem of learning situation models for providing context-aware services. Context for modeling human behavior in a smart environment is represented by a situation model describing environment, users, and their activities. A framework for acquiring and evolving different layers of a situation model in a smart environment is proposed. Different learning methods are presented as part of this framework: role detection per entity, unsupervised extraction of situations from multimodal data, supervised learning of situation representations, and evolution of a predefined situation model with feedback. The situation model serves as frame and support for the different methods, permitting to stay in an intuitive declarative framework. The proposed methods have been integrated into a whole system for smart home environment. The implementation is detailed, and two evaluations are conducted in the smart home environment. The obtained results validate the proposed approach.

Ideally, sensors are tasked to perform specific functions to maximize their effectiveness. Many sensors are capable of collecting more data than is needed for a particular purpose, leading to the potential to enhance a sensor’s utilization by allowing it to be re-tasked in real time when it is determined that sufficient data has been acquired to meet the first task’s requirements. In addition, understanding a situation involving fast-traveling objects in space may require inputs from more than one sensor, leading to a need for information sharing in real time. Observations that are not processed in real time may be archived to support forensic analysis for accidents and for long-term studies. Space Situational Awareness (SSA) requires an extremely robust distributed software platform to appropriately manage the collection and distribution for both real-time decision-making as well as for analysis. FAWKES is being developed as a Joint Space Operations Center (JSPOC) Mission System (JMS) compliant implementation of the AFRL Phoenix information management architecture. It implements a pub/sub/archive/query (PSAQ) approach to communications designed for high performance applications. FAWKES provides an easy to use, reliable interface for structuring parallel processing, and is particularly well suited to the requirements of SSA. In addition to supporting point-to-point communications, it offers an elegant and robust implementation of collective communications, to scatter, gather and reduce values. A query capability is also supported that enhances reliability. Archived messages can be queried to re-create a computation or to selectively retrieve previous publications. PSAQ processes express their role in a computation by subscribing to their inputs and by publishing their results. Sensors on the edge can subscribe to inputs by appropriately authorized

    A new ESA Programme on Space Situational Awareness (SSA) has been approved during the ESA Council at Ministerial level in November 2008. A preparatory phase is in progress, covering the timeframe 2009 -2012. It concentrates on the architectural design of the SSA System, its governance and data policy, as well as on the provision of precursor services based on the federation of existing National and European assets. A continuation of the SSA programme will be proposed at the next Ministerial Council for the years 2012 and onwards. The SSA Preparatory Programme covers three distinct segments, namely: -Space Surveillance and Tracking of artificial objects orbiting the Earth -Space Weather -Near Earth Objects Each of the above segments has a strong relation with Science and is supported by specific RD Programmes at National, EC and ESA levels. In this paper, the scientific aspects of the three SSA Segments are outlined and the following main topics developed: • Space Surveillance: statistical models of the evolution of the space debris population in Earth-bound orbits, study of active mitigation measures, impact analysis, tracking and char-acterisation principles based on radar and optical techniques. • Space Weather: awareness of the natural space environment, detection and forecasting of space weather effects and interferences, analysis of appropriate ground and space-based sensors for the monitoring of the Sun, the solar wind, the radiation belts, the magnetosphere and the ionosphere. • Near Earth Objects (NEOs): methods for determination of physical characteristics of newly discovered objects, study of appropriate sensors based on radar and optical techniques, iden-tification and ranking of collision risks of NEOs with the Earth, study of possible mitigation measures (e.g. Don Quichotes project). The research topics undertaken during the preparatory programme, as well as those foreseen during the next phase, possibly with a strong international cooperation

    The growth and proliferation of technologies in the field of sensor networking and mobile computing have led to the emergence of diverse applications that process and analyze sensory data on mobile devices such as a smart phone. However, the real power to make a significant impact on the area of developing these applications rests not merely on deploying the technologies, but on the ability to perform real-time, intelligent analysis of the data streams that are generated by the various sensors. In this chapter, we present a novel approach for Situation-Aware Adaptive Processing (SAAP) of data streams for pervasive computing environments. This approach uses fuzzy logic principles for modelling and reasoning about uncertain situations, and performs gradual adaptation of parameters of data stream mining algorithms in real-time according to availability of resources and the occurring situations.

    Solving different scientific problems for space applications demands implementation of observations, measurements or realization of active experiments during time intervals in which specific geometric and physical conditions are fulfilled. The solving of situational problems for determination of these time intervals when the satellite instruments work optimally is a very important part of all activities on every stage of preparation and realization of space missions. The elaboration of universal, flexible and robust approach for situation analysis, which is easily portable toward new satellite missions, is significant for reduction of missions' preparation times and costs. Every situation problem could be based on one or more situation conditions. Simultaneously solving different kinds of situation problems based on different number and types of situational conditions, each one of them satisfied on different segments of satellite orbit requires irregular calculations. Three formal approaches are presented. First one is related to situation problems description that allows achieving flexibility in situation problem assembling and presentation in computer memory. The second formal approach is connected with developing of situation problem solver organized as processor that executes specific code for every particular situational condition. The third formal approach is related to solver parallelization utilizing threads and dynamic scheduling based on "pool of threads" abstraction and ensures a good load balance. The developed situation problems solver is intended for incorporation in the frames of multi-physics multi-satellite space mission's design and simulation tools.

    With so many terms available to define the same thing, it would seem nearly irresponsible to introduce yet another term (complex situation) to describe a phenomenological state of such as a system. However, a complex situation infers both a broader meaning and imposes a different perspective. Complex in this context is dependent on understanding and reality rather than observer and knowledge.   Situation imposes a gestalt that cannot be characterized within a singular perspective that relegates paradox to a superior/subordinate hierarchy. This also infers that complex situation has no monotonic definition or each definition is by default incomplete. Therefore the perennial derivations for systems such as complex systems, system of systems, federation of systems is no longer a sufficient descriptor for complex situation.  Ergo system and its genealogy lack the constitution to define complex situations. The books' intent is to explore this pathology through a series of papers written by authors that work in ...

    2004-06-01

    Sociocultural theories of learning such as Wenger and Lave's situated learning have been suggested as alternatives to cognitive theories of learning like constructivism. This article examines situated learning within the context of computer science (CS) education. Situated learning accurately describes some CS communities like open-source software development, but it is not directly applicable to other CS communities, especially those that deal with non-CS application areas. Nevertheless, situated learning can inform CS education by analyzing debates on curriculum and pedagogy within this framework. CS educators should closely examine professional CS communities of practice and design educational activities to model the actual activities of those communities.

  5. An Ontology For Mobile Situation Aware Systems

    Paul F O'Brien

    2008-05-01

    Full Text Available This paper introduces a novel design artefact, namely a generic situation management ontology based on situation theory. This ontology contributes to the foundation knowledge base of mobile service delivery systems for future research and systems design. It demonstrates the applicability, and feasibility of using situation theory in the design of reactive information systems. The support within the ontology for context based filtering for situation detection also contributes to the efficiency of implementation and operation of situation driven reactive information systems. Highly mobile people (HMPs require flexible, reactive service delivery due to their regularly changing location and activities and the lack of a wired network connection. A mobile service delivery system should be able to detect relevant events that occur such as change of location, availability of new last-minute specials, sales opportunities and safety issues and then reactively take action in response to these events. This paper describes a generic situation management ontology that was developed in OWL using the ontology development tool, Protégé. The ontology is combined with domain specific classes in the travel domain to create a travel situation management ontology that can be used as the basis for a ubiquitous mobile travel service application. Using a typical independent traveller scenario, the travel situation management ontology is instantiated to demonstrate its effectiveness.

  6. Increasing situational awareness in DVE with advanced synthetic vision

    Science.gov (United States)

    Schafhitzel, T.; Hoyer, M.; Völschow, P.

    2013-05-01

    One of the major causes for hazardous situations in aviation is the lack of a pilot's situational awareness. Common causes for degraded situational awareness are Brownout and Whiteout situations, low level flights, and flights in DVE. In this paper, we propose Advanced Synthetic Vision (ASV), a modern situational awareness solution. ASV combines both Synthetic Vision and Enhanced Vision in order to provide the pilot most timeliness information without being restricted in the spatial coverage of the synthetic representation. The advantages to a common Enhanced Synthetic Vision System are the following: (1) ASV uses 3D ladar data instead of a 2D sensor. The 3D point cloud is classified in real-time to distinguish between ground, wires, poles and buildings; (2) the classified sensor data is fused with onboard data base contents like elevation or obstacles. The entire data fusion is performed in 3D, i.e. output is a merged 3D scenario instead of a blended 2D image. Once the sensor stopped recording due to occlusion, ASV switches to pure data base mode; (3) the merged data is passed to a 3D visualization module, which is fully configurable in order to support synthetic views on head down displays as well as more abstract augmented representations on helmet mounted displays; (4) the extendable design of ASV supports the graphical linking of functions like 3D landing aid, TAWS, or navigation aids.

    A great deal of effort has been invested in attempts to define situational awareness, and subsequently to measure this construct. However, relatively less work has focused on the sensitivity of these measures to manipulations that affect the SA of the pilot. This investigation was designed to manipulate SA and examine the sensitivity of commonly used measures of SA. In this experiment, we tested the most commonly accepted measures of SA: SAGAT, objective performance measures, and SART, against different levels of SA manipulation to determine the sensitivity of such measures in the rotorcraft flight environment. SAGAT is a measure in which the simulation blanks in the middle of a trial and the pilot is asked specific, situation-relevant questions about the state of the aircraft or the objective of a particular maneuver. In this experiment, after the pilot responded verbally to several questions, the trial continued from the point frozen. SART is a post-trial questionnaire that asked for subjective SA ratings from the pilot at certain points in the previous flight. The objective performance measures included: contacts with hazards (power lines and towers) that impeded the flight path, lateral and vertical anticipation of these hazards, response time to detection of other air traffic, and response time until an aberrant fuel gauge was detected. An SA manipulation of the flight environment was chosen that undisputedly affects a pilot's SA-- visibility. Four variations of weather conditions (clear, light rain, haze, and fog) resulted in a different level of visibility for each trial. Pilot SA was measured by either SAGAT or the objective performance measures within each level of visibility. This enabled us to not only determine the sensitivity within a measure, but also between the measures. The SART questionnaire and the NASA-TLX, a measure of workload, were distributed after every trial. Using the newly developed rotorcraft part-task laboratory (RPTL) at NASA Ames

    Full Text Available A consistent eating style might be beneficial to avoid overeating in a food-rich environment. Eating consistency entails maintaining a similar dietary pattern across different eating situations. This construct is relatively under-studied, but the available evidence suggests that eating consistency supports successful weight maintenance and decreases risk for metabolic syndrome and cardiovascular disease. Yet, personality and situation predictors of consistency have not been studied.A community-based sample of 164 women completed various personality tests, and 139 of them also reported their eating behaviour 6 times/day over 10 observational days. We focused on observations with meals (breakfast, lunch, or dinner. The participants indicated if their momentary eating patterns were consistent with their own baseline eating patterns in terms of healthiness or size of the meal. Further, participants described various characteristics of each eating situation.Eating consistency was positively predicted by trait self-control. Eating consistency was undermined by eating in the evening, eating with others, eating away from home, having consumed alcohol and having undertaken physical exercise. Interactions emerged between personality traits and situations, including punishment sensitivity, restraint, physical activity and alcohol consumption.Trait self-control and several eating situation variables were related to eating consistency. These findings provide a starting point for targeting interventions to improve consistency, suggesting that a focus on self-control skills, together with addressing contextual factors such as social situations and time of day, may be most promising. This work is a first step to provide people with the tools they need to maintain a consistently healthy lifestyle in a food-rich environment.

    Qualitative nurse researchers are required to make deliberate and sometimes complex methodological decisions about their work. Methodology in qualitative research is a comprehensive approach in which theory (ideas) and method (doing) are brought into close alignment. It can be difficult, at times, to understand the concept of methodology. The purpose of this research column is to: (1) define qualitative methodology; (2) illuminate the relationship between epistemology, ontology and methodology; (3) explicate the connection between theory and method in qualitative research design; and 4) highlight relevant examples of methodological decisions made within cardiovascular nursing research. Although there is no "one set way" to do qualitative research, all qualitative researchers should account for the choices they make throughout the research process and articulate their methodological decision-making along the way.

    Full Text Available This paper presents recent trends and flows of labor migration and its impact on economic and social life. Main aim of this research sets up the influence of the migration on the European economics and its competitiveness. Methods of research are: method of comparison, analysis method, method of deduction, method of statistics, modeling method. The economic impact of migration has been intensively studied but is still often driven by ill-informed perceptions, which, in turn, can lead to public antagonism towards migration. These negative views risk jeopardising efforts to adapt migration policies to the new economic and demographic challenges facing many countries. Migration Policy looks at the evidence for how immigrants affect the economy in three main areas: The labour market, public purse and economic growth. In Europe, the scope of labour mobility greatly increased within the EU/EFTA zones following the EU enlargements of 2004, 2007 and 2014-2015. This added to labour markets’ adjustment capacity. Recent estimates suggest that as much as a quarter of the asymmetric labour market shock – that is occurring at different times and with different intensities across countries – may have been absorbed by migration within a year.

    1995-08-01

    Social workers in health care settings are constantly required to make clinical decisions about patient care and treatment. Although much attention has been devoted to the normative or ethical aspects of decision making in such settings, little attention has been given to the typical situational aspects of decisions social workers must make in health care. This article discusses four types of clinical decision situations--operational, strategic, authoritative, and crisis--and presents a model to assist in analyzing their components and requirements. Case vignettes drawn from practice experience illustrate each type of decision-making situation. The article concludes that knowledge of the situational aspects of practice decision making can be helpful to practitioners by enabling them to sort out courses of action and intervention.

In terms of attack, to improve the accuracy of evaluation, a situation assessment method of DDoS attack based on the information of data packet was proposed. In terms of vulnerability, a improved Common Vulnerability Scoring System (CVSS was raised and maked the assessment more comprehensive. In terms of node weights, the method of calculating the combined weights and optimizing the result by Sequence Quadratic Program (SQP algorithm which reduced the uncertainty of fusion was raised. To verify the validity and necessity of the method, a testing platform was built and used to test through evaluating 2000 DAPRA data sets. Experiments show that the method can improve the accuracy of evaluation results.

    Full Text Available Background: Emotional context may play a crucial role in movement production. According to simulation theories, emotional states affect motor systems. The aim of this study was to compare postural responses assessed by posturography and electromyography when subjects were instructed to imagine themselves in a painful or a non-painful situation.Methods: Twenty-nine subjects (22.3 ± 3.7 years participated in this study. While standing quietly on a posturographic platform, they were instructed to imagine themselves in a painful or non-painful situation. Displacement of the centre of pressure (COP, leg muscle electromyographic activity, heart rate, and electrodermal activity were assessed in response to painful and non-painful situations.Results:The anteroposterior path was shorter (p<0.05 when subjects imagined themselves in a painful situation (M = 148.0 ± 33.4 mm compared to a non-painful situation (158.2 ± 38.7 mm. Higher Tibialis Anterior (TA activity (RMS-TA = 3.38 ± 1.95 % vs 3.24 ± 1.85 %; p < 0.001 and higher variability of Soleus (SO activity (variation coefficient of RMS-SO = 13.5 ± 16.2 % vs M = 9.0% ± 7.2 %; p<0.05 were also observed in painful compared to non-painful situations. No significant changes were observed for other physiological data Conclusion: This study demonstrates that simulation of painful situations induces changes in postural control and leg muscle activation compared to non-painful situations, as increased stiffness was demonstrated in response to aversive pictures in accordance with previous results.

  3. Decoupling, situated cognition and immersion in art.

    Situated cognition seems incompatible with strong decoupling, where representations are deployed in the absence of their targets and are not oriented toward physical action. Yet, in art consumption, the epitome of a strongly decoupled cognitive process, the artwork is a physical part of the environment and partly controls the perception of its target by the audience, leading to immersion. Hence, art consumption combines strong decoupling with situated cognition.

    2007-01-01

    In high-risk environments such as air traffic control, leadership on different levels plays a certain role in establishing, promoting, and maintaining a good safety culture. The current study aimed to investigate how leadership styles, leadership style adaptability, and over and under task leadership behavior differed across situations, operative conditions, leadership structures, and working tasks in an air traffic control setting. Study locations were two air traffic control centers in Sweden with different operational conditions and leadership structures, and an administrative air traffic management unit. Leadership was measured with a questionnaire based on Leader Effectiveness and Adaptability Description (LEAD; Blanchard, Zigarmi & Zigarmi, 2003; Hersey & Blanchard, 1988). The results showed that the situation had strong impact on the leadership in which the leadership behavior was more relationship oriented in Success and Group situations than in Hardship and Individual situations. The leadership adaptability was further superior in Success and Individual situations compared with Hardship and Group situations. Operational conditions, leadership structures and working tasks were, on the other hand, not associated with leadership behavior.

  6. Treemap Visualizations for Space Situational Awareness

    Science.gov (United States)

    Ianni, J.; Gorrell, Z.

    Making sense of massive data sets is a problem for many military domains including space. With unwieldy big data sets used for space situational awareness (SSA), important trends and outliers may not be easy to spot especially not at-a-glance. One method being explored to visualize SSA data sets is called treemapping. Treemaps fill screen space with nested rectangles (tiles) of various sizes and colors to represent multiple dimensions of hierarchical data sets. By mapping these dimensions effectively with a tiling algorithm that maintains an appropriate aspect ratio, patterns can emerge that often would have gone unnoticed. The ability to interactively perform range filtering (in our case with sliders) and object drill-downs (hyperlinking the tiles) make this technology powerful for in-depth analyses in addition to at-a-glance awareness. For one SSA analysis, the tiles could represent satellites that are grouped by country, sized by apogee, and colored/shaded by the launch date. Filter sliders could allow apogee range or launch dates to be narrowed for better resolution of a smaller data set. The application of this technology for the Joint Space Operations Center (JSpOC) Mission System (JMS) is being explored on a DARPA Small Business Innovative Research (SBIR) effort as a plug-in to the existing User-Defined Operational Picture (UDOP). In addition, visualization of DARPA OrbitOutlook small telescope data will be demonstrated. This research will investigate what SSA analyses are best served by treemaps, the best tiling algorithms for these problems, and how the treemaps should be integrated into the existing JMS UDOP workflow. Finally, we introduce a variation of treemaps that help leaders allocate their time to tasks based on importance and urgency.

  9. Preparing Anesthetists to Manage Cannot Intubate/Cannot Ventilate Situations.

    Wofford, Kenneth A

    2017-01-01

    Cannot intubate/cannot ventilate (CICV) situations during anesthesia are rare, potentially catastrophic to the patient, and difficult to predict. Widely adopted practice guidelines advocate an algorithmic approach to CICV situations in which the anesthetist: (a) recognizes the CICV situation, (b) calls for help, (c) steadily progresses through a variety of methods to ventilate the patient and secure the airway, (d) restores ventilation via an infraglottic airway if the patient cannot be safely awakened prior to becoming moribund. Despite widespread consensus that rapid progression to placement of an infraglottic airway is critical to the survival of the patient in a CICV situation, the rarity of CICV is a substantial barrier for anesthetists attempting to gain and maintain skill at placing infraglottic airways. Peer-reviewed literature reveals a number of themes relevant to training anesthetists in infraglottic airway placement. Specific training in infraglottic airway access consistently decreased the time required for anesthetists to decide to place an infraglottic airway. No one approach or method for placing an infraglottic airway was consistently faster or more successful. Model fidelity (i.e., the use of low-fidelity task trainers vs. high-fidelity simulated patients) during teaching did not affect the performance of anesthetists at placing infraglottic airways, and performance rapidly plateaued after five repetitions during teaching. Finally, skill at placing an infraglottic airway was sustained for 6 to 12 months after training. These findings have implications for how nurse anesthetists should learn and sustain the skill of infraglottic airway placement. Nurse anesthetists should undergo initial training that requires the repetitive placement of infraglottic airways, and receive sustainment training every 6 to 12 months thereafter. Although rarely used, the skill of an anesthetist in infraglottic airway placement can mean the difference between life and

  10. Situated learning methodologies and assessment in civil engineering structures education

    Science.gov (United States)

    Bertz, Michael Davis

    This thesis describes an overarching study of civil engineering undergraduate structural education through student performance in recalling and applying basic structural engineering knowledge, and the viability of alternative situated learning environments for more effectively supporting the learning of this knowledge. To properly ground this study, a thorough investigation of related work in assessment, cognitive science, educational technology, and design education was completed, with connections and applications to civil engineering education highlighted. The experimental work of the thesis is organized into three parts: an assessment of civil engineering undergraduates' fundamental structural engineering knowledge and abilities; the development and testing of a software support environment for situated learning, the Civil Engineering Learning Library (CELL); and, the implementation and evaluation of the design studio, a pedagogical model for situated learning in the classroom. The results of the assessment study indicate that civil engineering seniors (and also students earlier in the curriculum) have difficulty retaining and applying basic knowledge of structural behavior, especially doing so in a flexible fashion in design situations. The survey also suggests that visualization plays an important role in understanding structural behavior. Tests with the CELL system show that a cognitively-flexible multimedia environment can support structural learning, but were inconclusive about whether the computer-based system helped the students to learn better than conventional classroom lecture. Two trial implementations of the design studio indicate that the studio model can serve as a powerful situated learning environment, and that it can be scaled up to reasonable class sizes. Significant requirements are associated with this model, however, primarily in faculty involvement, but also in physical resources and student time. In addition to these conclusions about the

    2013-12-01

    This paper discusses about the design of a Situation Awareness (SA) system to support vessel crews and control room operators in improving the decision making process. The architecture of the system is ontology based. The vessel crews and control room operators may face a loss of SA. They may have limited cognitive abilities which make it difficult to make a decision in a high stress level, short time availability and continuously evolving situation with incomplete information. In this work, we describe the application of Semantic Web Rule Language to represent corresponding knowledge in the maritime surveillance domain. The result of this research will demonstrate that an ontology based system can be used to remodel the information into a meaningful and valuable form to predict the future states of SA and improve the decision making process.

    Full Text Available The paper introduced the basic model of process of safe ship control in a collision situation using a game model with j objects, which includes non-linear state equations and non-linear, time varying constraints of the state variables as well as the quality game control index in the forms of the game integral payment and the final payment. Approximated model of the process control as the model of multi-step matrix game in the form of dual linear programming problem has been adopted here. The Game Ship Control GSC computer program has been designed in the Matlab/Simulink software in order to determine the own ship's safe trajectory. These considerations have been illustrated with examples of a computer simulation using an GSC program for determining the safe ship's trajectory in real navigational situation. Simulation research were passed for five sets of strategies of the own ship and met ships.

    2008-01-01

    Both the basic educational contents for students and study programs for science teachers include several topics in physics and astronomy, from the simplest ones to others as advanced as nuclear fusion to explain stellar evolution and space-time geometry for an approach to modern cosmology. In all these subjects, and most often in the simplest ones, alternative conceptions emerge, as both groups reach science course with preconstructed and consistent models of the universe surrounding them. In this work we present a series of basic questionings that make us reflect on the present situation of the teaching-learning relationship in astronomy within the framework of formal education. We then briefly explain our project aiming at finding the real learning situation of both students and prospective primary-school teachers in astronomical topics and, from the expected results of it, we point towards the need to develop didactic tools that could contribute to improve formal education in astronomy issues.

    2010-01-01

    This study compared pilot situation awareness across three traffic management concepts. The Concepts varied in terms of the allocation of traffic avoidance responsibility between the pilot on the flight deck, the air traffic controllers, and a conflict resolution automation system. In Concept 1, the flight deck was equipped with conflict resolution tools that enable them to fully handle the responsibility of weather avoidance and maintaining separation between ownship and surrounding traffic. In Concept 2, pilots were not responsible for traffic separation, but were provided tools for weather and traffic avoidance. In Concept 3, flight deck tools allowed pilots to deviate for weather, but conflict detection tools were disabled. In this concept pilots were dependent on ground based automation for conflict detection and resolution. Situation awareness of the pilots was measured using online probes. Results showed that individual situation awareness was highest in Concept 1, where the pilots were most engaged, and lowest in Concept 3, where automation was heavily used. These findings suggest that for conflict resolution tasks, situation awareness is improved when pilots remain in the decision-making loop.

However, in recent years, Mexican public politics are looking after the improvement of women quality of life, particularly in the last ten years. Implementing governmental actions to prevent different ways of discrimination towards women, looking for gender equity in the Mexican society. In particular, Tepexilotla is a community of the Mexican state of Veracruz, that despite of being so small village, is actively its development. Regarding gender, after four years of continuous work in the community, there are initiating changes in social and familiar relationships, because is getting each time more involved in the economical activities, such as agroecotourism. Specifically, these have been observed on relation to their participation in the agro-ecoturistic activity that has started to be a resource of employment and development in the town. As far as Tepexilotla has been received the training from “Colegio de Postgraduados” to design rural touristic routes that have encouraged this activity en this community (between other active-research and projects in that microregion. Between these projects, Rural turism emerged from a integral participative diagnostic (DIP to detect potential projects of the microregion, where the people from the community raise their interest to learn “touristic guides” habilities, because they were interested on showing prehispanic ruins as well as caves and ecological areas, that emerged as potential resources for development. In this way, the project borned to achieve agro-ecoturistic activities that help to potentialize the agricultural, ecological and touristic activities, with the gender perspective view, (considering both men and women.

    Full Text Available Abstract Background This study explores the role of pleasure in decision making. Results In Experiment 1, 12 subjects were presented with a questionnaire containing 46 items taken from the literature. Twenty-three items described a situation where a decision should be made and ended with a suggested solution. The other items served as filler items. The subjects were requested not to make a decision but to rate the pleasure or displeasure they experienced when reading the situation described in the item. The subjects' ratings were then compared to the decisions on the same situations made by the other subjects of the studies published by other workers. The ratings of pleasure/displeasure given by our subjects correlated significantly with the choices published by other authors. This result satisfies a necessary condition for pleasure to be the key of the decision making process in theoretical situations. In Experiment 2, a new group of 12 subjects rated their experience of pleasure/displeasure when reading various versions of 50 situations taken from daily life where an ethical decision had to be made (Questionnaire I including 200 items. This was followed by a multiple-choice test with the 50 situations (Questionnaire II using the same 200 items and offering the various behaviors. Subjects tended to choose ethical and unethical responses corresponding to their highest pleasure rating within each problem. In all cases the subjects' behavior was higher than chance level, and thus, followed the trend to maximize pleasure. In Experiment 3, 12 subjects reading 50 mathematical short problems followed by correct and incorrect versions of the answer to the problem (Questionnaire III, including 200 items. This was followed by a multiple-choice mathematical test with the 50 problems (Questionnaire IV using the same 200 items and offering the correct and incorrect answers.

    Full Text Available Objective.Identify the actions conducted by primary health care nurses for women in situations of domestic violence. Methodology. Exploratory-descriptive study with a qualitative approach. Participants were 17 nurses who worked in the Basic Health Unit in a city in the interior of Rio Grande do Sul, Brazil. The data was collected through semi-structured interviews and the information processing was performed using the interview content analysis technique. Results. By acting in a context of the violence, the nurses describe some elements and strategies they use that allow recognition and action to combat violence, namely: acceptance and empathy, establishing a bond of trust between the professional and the woman, dialogue, and intent listening. The limitations mentioned by participants were: lack of professional training to address the situation, feeling of unpreparedness, lack of time for the workload, the professional's difficulty in recognizing and dealing with violence given its complexity, low efficiency of the service network, and the sense of professional impotence against the gravity and complexity involved in violence. Conclusion. The participants are not adequately prepared to care for women in situations of domestic violence. It is necessary that this issue be addressed in the training of nursing professionals.

  6. A seamless ubiquitous emergency medical service for crisis situations.

    Lin, Bor-Shing

    2016-04-01

    In crisis situations, a seamless ubiquitous communication is necessary to provide emergency medical service to save people's lives. An excellent prehospital emergency medicine provides immediate medical care to increase the survival rate of patients. On their way to the hospital, ambulance personnel must transmit real-time and uninterrupted patient information to the hospital to apprise the physician of the situation and provide options to the ambulance personnel. In emergency and crisis situations, many communication channels can be unserviceable because of damage to equipment or loss of power. Thus, data transmission over wireless communication to achieve uninterrupted network services is a major obstacle. This study proposes a mobile middleware for cognitive radio (CR) for improving the wireless communication link. CRs can sense their operating environment and optimize the spectrum usage so that the mobile middleware can integrate the existing wireless communication systems with a seamless communication service in heterogeneous network environments. Eventually, the proposed seamless mobile communication middleware was ported into an embedded system, which is compatible with the actual network environment without the need for changing the original system architecture.

    In this study, a situation-augmented display for unmanned aerial vehicle (UAV) monitoring was designed, and its effects on operator performance and mental workload were examined. The display design was augmented with the knowledge that there is an invariant flight trajectory (formed by the relationship between altitude and velocity) for every flight, from takeoff to landing. 56 participants were randomly assigned to the situation-augmented display or a conventional display condition to work on 4 (number of abnormalities) x 2 (noise level) UAV monitoring tasks three times. Results showed that the effects of situation-augmented display on flight completion time and time to detect abnormalities were robust under various workload conditions, but error rate and perceived mental workload were unaffected by the display type. Results suggest that the UAV monitoring task is extremely difficult, and that display devices providing high-level situation-awareness may improve operator monitoring performance.

    We survey the job situation of women in astronomy in Germany and of German women abroad and review indicators for their career development. Our sample includes women astronomers from all academic levels from doctoral students to professors, as well as female astronomers who have left the field. We find that networking and human support are among the most important factors for success. Experience shows that students should carefully choose their supervisor and collect practical knowledge abroad. We reflect the private situation of female German astronomers and find that prejudices are abundant, and are perceived as discriminating.We identify reasons why women are more likely than men to quit astronomy after they obtain their PhD degree. We give recommendations to young students on what to pay attention to in order to be on the successful path in astronomy.

    The need for assessing internal radiation doses in emergency situations was demonstrated after accidents in Brazil, Ukraine and other countries. Lately more and more concern has been expressed regarding malevolent use of radiation and radioactive materials. The scenarios for such use are more difficult to predict than for nuclear power plant or weapons accidents. Much of the results of the work done in the IRADES project can be adopted for use in various accidental situations involving radionuclides that are not addressed in this report. If an emergency situation occurs in only one or a few of the Nordic countries, experts from the other countries could be called upon to assist in monitoring. A big advantage is then our common platform. In the Nordic countries much work has been put down on quality assurance of measurements and on training of dose assessment calculations. Attention to this was addressed at the internal dosimetry course in October 2005. Nordic emergency preparedness exercises have so far not included training of direct measurements of people in the early phase of an emergency. The aim of the IRADES project was to improve the preparedness especially for thyroid measurements. The modest financial support did not enable the participants to make big efforts but certainly acted as a much appreciated reminder of the importance of being prepared also to handle situations with malevolent use of radioactive materials. It was left to each country to decide to which extent to improve the practical skills. There is still a need for detailed national implementation plans. Measurement strategies need to be developed in each country separately taking into account national regulations, local circumstances and resources. End users of the IRADES report are the radiation protection authorities. (au)

    1996-11-01

    The transition to a competitive electricity market will require a more careful approach to intersystem coordination - planning, operations and pricing - than policy makers have yet recognized. But there`s still time to get it right. States have scheduled the starting date for retail wheeling. The government has opened the grid. Politically correct regulatory agencies declare that nobody will escape stranded costs. Engineers still warn about the need to maintain system reliability. But free marketeers have a ready answer: {open_quotes}Don`t worry. The market will furnish the solutions.{close_quotes} The authors would argue otherwise. Not because a market could not provide solutions, but because whole sectors of the electricity supply market have-so far-been omitted from the market. Hurried deregulation on a piecemeal basis may create some local successes, but also lead to unanticipated failures in other parts of the system. A workably competitive market must value all the important aspects in the system, otherwise piecemeal incentives may invite failure. The savings and loan debacle, the privatization of an oligopolistic generating sector in the United Kingdom, and the liberalization of long-distance communications in Canada followed by the financial collapse of most new entrants within a year are notable examples of misguided public policies that neglected a systems overview and did not get it right the first time.

    Full Text Available The present paper studies the evolution of a set of USA firms during the years 1993–2002. The firms that faced a difficult economic and financial situation in 1993 were considered to be in a distress situation. The aim of this study is to explore if the evolution of this situation depends on the initial features of the distress or if it concerns certain firms' characteristics. If the evolution is independent from the above, the management decisions become crucial in critical times. For the analysis we used a Multidimensional Scaling methodology where the firms are represented in a consensus map according to symptom variables, reaction variables, and recovering variables.

  16. Resource Management in Constrained Dynamic Situations

    Science.gov (United States)

    Seok, Jinwoo

    Resource management is considered in this dissertation for systems with limited resources, possibly combined with other system constraints, in unpredictably dynamic environments. Resources may represent fuel, power, capabilities, energy, and so on. Resource management is important for many practical systems; usually, resources are limited, and their use must be optimized. Furthermore, systems are often constrained, and constraints must be satisfied for safe operation. Simplistic resource management can result in poor use of resources and failure of the system. Furthermore, many real-world situations involve dynamic environments. Many traditional problems are formulated based on the assumptions of given probabilities or perfect knowledge of future events. However, in many cases, the future is completely unknown, and information on or probabilities about future events are not available. In other words, we operate in unpredictably dynamic situations. Thus, a method is needed to handle dynamic situations without knowledge of the future, but few formal methods have been developed to address them. Thus, the goal is to design resource management methods for constrained systems, with limited resources, in unpredictably dynamic environments. To this end, resource management is organized hierarchically into two levels: 1) planning, and 2) control. In the planning level, the set of tasks to be performed is scheduled based on limited resources to maximize resource usage in unpredictably dynamic environments. In the control level, the system controller is designed to follow the schedule by considering all the system constraints for safe and efficient operation. Consequently, this dissertation is mainly divided into two parts: 1) planning level design, based on finite state machines, and 2) control level methods, based on model predictive control. We define a recomposable restricted finite state machine to handle limited resource situations and unpredictably dynamic environments

  17. Bringing the Psychology of Situations into Flow Research: Personality and Situation Characteristics as Predictors of Flow

    Full Text Available The aim of the present study was to extend the existing findings on environmental flow precursors by adopting the DIAMONDS taxonomy of psychologically meaningful situation characteristics as a comprehensive theoretical framework. It was hypothesized that an individual's perception of the flow-related situation, particularly the dimensions of duty, intellect and positivity, would represent a more powerful predictor of the intensity of flow as compared to his or her basic personality traits. The first sample consisted of 169 employees who had to focus on the most engaging work-related event they had experienced in the past three months. They rated the characteristics of that situation and estimated the intensity of their flow experience. The second sample consisted of 96 students who participated in a challenging group activity. After the activity, they filled-in the same questionnaires as the first sample. Participants from both samples also rated their basic personality traits. Despite differences in the settings and flow-related situations evaluated, the obtained findings were similar for the two samples studied. While the association between flow and personality was weak, the situation characteristics were more strongly related to flow. Although the two samples differed with respect to the mean levels of the flow-related situation characteristics, regression analyses yielded similar results, suggesting that the intensity of flow at work and in studying is most prominently determined by situation characteristics related to intellect and positivity. Stable personality characteristics, on the other hand, had low predictive power in explaining the intensity of flow.

    2005-09-01

    Over three decades before Einstein's year of miracles, the American humorist Mark Twain published an essay titled "My Watch," in which he recounts his experiences with a previously reliable pocket watch and those who tried to rehabilitate it. He begins his essay by confessing his first error: My beautiful new watch had run eighteen months without losing or gaining, and without breaking any part of its machinery or stopping. I had come to believe it infallible in its judgments about the time of day, and to consider its constitution and its anatomy imperishable. But at last, one night, I let it run down. I grieved about it as if it were a recognized messenger and forerunner of calamity. Twain then sets the watch by guess, and takes it to the "chief jeweler's to set it by the exact time." To Twain's dismay, the jeweler insists on opening it up and adjusting the regulator inside the watch, and the watch begins to gain time. It gained faster and faster day by day. Within a week it sickened to a raging fever, and its pulse went up to a hundred and fifty in the shade. At the end of two months, it had left all the timepieces of the town far in the rear, and was a fraction over thirteen days ahead of the almanac. It was away into November enjoying the snow, while the October leaves were still turning. It hurried up house rent, bills payable, and such things, in such a ruinous way that I could not abide it.

    This paper studies the dangerous situation (DS) in a synchronized flow model. The DS on the two branches of the fundamental diagram are investigated, respectively. It is shown that different relationship between DS probability and the density exists in the synchronized flow and in the jams. Moreover, we prove that there is no DS caused by non-stopped car although the model itself is a non-exclusion process. We classify the DS into four sub-types and study the probability of these four sub-types. The simulation result is consistent with the real traffic.

Therapeutic failures are common. Several factors may contribute to the problems of chemotherapy, including differences in the epidemiology of the disease, difficulties in the diagnosis and staging of the infection, availability, distribution and pharmacologic properties of drugs, standardization of treatment regimens, response to therapy, follow-up period, and relapses and clinical trials. The new therapeutic approaches include the development and approval of new drugs, the use of new therapeutic regimens, the study of drug combinations, and the development of new formulations.

    System concepts for network enabled image-based ISR (intelligence, surveillance, reconnaissance) is the major mission of Fraunhofer IITB's applied research in the area of defence and security solutions. For the TechDemo08 as part of the NATO CNAD POW Defence against terrorism Fraunhofer IITB advanced a new multi display concept to handle the shear amount and high complexity of ISR data acquired by networked, distributed surveillance systems with the objective to support the generation of a common situation picture. Amount and Complexity of ISR data demands an innovative man-machine interface concept for humans to deal with it. The IITB's concept is the Digital Map & Situation Surface. This concept offers to the user a coherent multi display environment combining a horizontal surface for the situation overview from the bird's eye view, an attached vertical display for collateral information and so-called foveatablets as personalized magic lenses in order to obtain high resolved and role-specific information about a focused areaof- interest and to interact with it. In the context of TechDemo08 the Digital Map & Situation Surface served as workspace for team-based situation visualization and analysis. Multiple sea- and landside surveillance components were connected to the system.

    Kachergis, George; Yu, Chen; Shiffrin, Richard M

    2013-01-01

    Previous research shows that people can use the co-occurrence of words and objects in ambiguous situations (i.e., containing multiple words and objects) to learn word meanings during a brief passive training period (Yu & Smith, 2007). However, learners in the world are not completely passive but can affect how their environment is structured by moving their heads, eyes, and even objects. These actions can indicate attention to a language teacher, who may then be more likely to name the attended objects. Using a novel active learning paradigm in which learners choose which four objects they would like to see named on each successive trial, this study asks whether active learning is superior to passive learning in a cross-situational word learning context. Finding that learners perform better in active learning, we investigate the strategies and discover that most learners use immediate repetition to disambiguate pairings. Unexpectedly, we find that learners who repeat only one pair per trial--an easy way to infer this pair-perform worse than those who repeat multiple pairs per trial. Using a working memory extension to an associative model of word learning with uncertainty and familiarity biases, we investigate individual differences that correlate with these assorted strategies.

  13. Modeling Being "Lost": Imperfect Situation Awareness

    Science.gov (United States)

    Middleton, Victor E.

    2011-01-01

    Being "lost" is an exemplar of imperfect Situation Awareness/Situation Understanding (SA/SU) -- information/knowledge that is uncertain, incomplete, and/or just wrong. Being "lost" may be a geo-spatial condition - not knowing/being wrong about where to go or how to get there. More broadly, being "lost" can serve as a metaphor for uncertainty and/or inaccuracy - not knowing/being wrong about how one fits into a larger world view, what one wants to do, or how to do it. This paper discusses using agent based modeling (ABM) to explore imperfect SA/SU, simulating geo-spatially "lost" intelligent agents trying to navigate in a virtual world. Each agent has a unique "mental map" -- its idiosyncratic view of its geo-spatial environment. Its decisions are based on this idiosyncratic view, but behavior outcomes are based on ground truth. Consequently, the rate and degree to which an agent's expectations diverge from ground truth provide measures of that agent's SA/SU.

    2000-04-01

    Nurses who had just completed their training in Scotland were interviewed with regard to their experiences on placements. The nurses had either completed a traditional training course or came from the first cohort of the Project 2000 diploma level course. The interviews focused on the way in which the student nurses had learned in their practice placements. The results suggest that the placement is a complex social and cognitive experience in which there are elements of situated learning. Acceptance into the community of practice is important but this can be separated, conceptually at least, into a social acceptance which might be extended to any student and a professional acceptance which relies on the display of appropriate competence. The nurses described the way in which their mentors had interacted with them in terms which suggested that cognitive apprenticeship strategies had been used to further their learning in practice. It is concluded that, in view of the central importance of the placement for training nurses, explicit use of mentoring techniques derived from situated learning and cognitive apprenticeship might be beneficial.

    2005-05-01

    Sensor management in support of situation assessment (SA) presents a daunting theoretical and practical challenge. We demonstrate new results using a foundational, joint control-theoretic approach to SA and SA sensor management that is based on three concepts: (1) a "dynamic situational significance map" that mathematically specifies the meaning of tactical significance for a given theater of interest at a given moment; (2) an intuitively meaningful and potentially computationally tractable objective function for SA, namely maximization of the expected number of targets of tactical interest; and (3) integration of these two concepts with approximate multitarget filters (specifically, first-order multitarget moment filters and multi-hypothesis correlator (MHC) engines). Under this approach, sensors will be directed to preferentially collect observations from targets of actual or potential tactical significance, according to an adaptively modified definition of tactical significance. Result of testing this sensor management algorithm with significance maps defined in terms of target's location, speed, and heading will be presented. Testing is performed against simulated data, and different sensor management algorithms including the proposed are compared.

  16. Situating math word problems: the story matters.

    Mattarella-Micke, Andrew; Beilock, Sian L

    2010-02-01

    In two experiments, we explored how the situation model of a math story problem impacts math problem performance. Participants completed multiplication story problems in which a set of objects was associated with or dissociated from a protagonist, making them more or less accessible in memory during answer retrieval. On the basis of previous findings that the sum of two numbers interferes with retrieval of their product, the number of objects in the math problem was either highly interfering ("9" for 4 x 5) or less interfering ("8" for 4 x 5) for multiplication retrieval in the problem. Participants made more errors in problem solving when highly interfering numerical content was associated with the protagonist and, thus, foregrounded. Moreover, the lower one's working memory, the bigger this effect. In sum, small changes in the situation model of a math story problem can harm performance. These changes shift the balance of factors that influence math performance away from math knowledge and toward individual differences in general cognitive capacity.

In order to predict the security situation more accurately, a quantitative prediction method of network security situation based on Wavelet Neural Network with Genetic Algorithm (GAWNN) is proposed. After analyzing the past and the current network security situation in detail, we build a network security situation prediction model based on wavelet neural network that is optimized by the improved genetic algorithm and then adopt GAWNN to predict the non-linear time series of network security situation. Simulation experiments prove that the proposed method has advantages over Wavelet Neural Network (WNN) method and Back Propagation Neural Network (BPNN) method with the same architecture in convergence speed, functional approximation and prediction accuracy. What is more, system security tendency and laws by which security analyzers and administrators can adjust security policies in near real-time are revealed from the prediction results as early as possible.

  20. A hierarchical algorithm for cyberspace situational awareness based on analytic hierarchy process

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    The existing network security management systems are unable either to provide users with useful security situation and risk assessment, or to aid administrators to make right and timely decisions based on the current state of network. These disadvantages always put the whole network security management at high risk. This paper establishes a simulation environment, captures the alerts as the experimental data and adopts statistical analysis to seek the vulnerabilities of the services provided by the hosts in the network. According to the factors of the network, the paper introduces the two concepts: Situational Meta and Situational Weight to depict the total security situation. A novel hierarchical algorithm based on analytic hierarchy process (AHP) is proposed to analyze the hierarchy of network and confirm the weighting coefficients. The algorithm can be utilized for modeling security situation, and determining its mathematical expression. Coupled with the statistical results, this paper simulates the security situational trends.Finally, the analysis of the simulation results proves the algorithm efficient and applicable, and provides us with an academic foundation for the implementation in the security situation.

    2011-01-01

    Historical researches focusing on the study of the ideas on madness and on psychiatry as a medical specialty in Argentina published until 1980 were few, and they were scattered throughout a time period covering more than a century. Some of them, however, constituted sources of useful data that contributed to subsequent developments which are still, in great measure, under way. New collective projects adopting new methodological approaches to address the subject have emerged in recent years. In this respect, the establishment of a vast plan for the research and compilation of primary sources, the organization and development of a formation of human resources that may adequately meet future research work, and a more solid assurance of the publication and divulgement of this research work are still pending. This article, of an introductory nature and predominantly descriptive and panoramic, reviews the main works and authors and their theoretical conceptions, situating them in the context of their time.

    We present a novel collaborative visual analytics application for cognitively overloaded users in the astrophysics domain. The system was developed for scientists needing to analyze heterogeneous, complex data under time pressure, and then make predictions and time-critical decisions rapidly and correctly under a constant influx of changing data. The Sunfall Data Taking system utilizes severalnovel visualization and analysis techniques to enable a team of geographically distributed domain specialists to effectively and remotely maneuver a custom-built instrument under challenging operational conditions. Sunfall Data Taking has been in use for over eighteen months by a major international astrophysics collaboration (the largest data volume supernova search currently in operation), and has substantially improved the operational efficiency of its users. We describe the system design process by an interdisciplinary team, the system architecture, and the results of an informal usability evaluation of the production system by domain experts in the context of Endsley?s three levels of situation awareness.

    Full Text Available The aim of this study is the description of modular structure of the academic discipline in accordance with the requirements of Federal State Educational Standards.Methods. The authors use the methods of standardization of the educational system that are based on educational theory quality measurement. As the process of learning does not depend on the perspective of the diagnostician, the objectification of the results has been achieved by using relative units, allowing the authors to compare the effectiveness of different stages of education quality assessment with quantitative methods. Furthermore, sampling method, correlation and comparative analysis of statistical significance of the obtained distributions have been used to exclude from analytical data the results that were not confirmed experimentally.Results. Statistical methods are presented in a complex, allowing the authors to receive experimental result at level of the statistical importance of psychological and pedagogical researches. According to ideas of the competence-based education and general theory of systems and educational qualimetry, it is shown that constructs of vocational training are problem, test and detailed designs included in structure of educational modules. Funds of estimated means have been used to measure the level of trainee’s competences: – problematic situation of uncertainty orientation for current control; – situations of test and project orientation for boundary control at the end of each module, intermediate control in the form of the exam held at the end of the semester, as well as state certification of control at the end of the study at the university.

    Since the days of Sputnik, the Air Force has maintained the surveillance of space and a position catalog of objects that can be tracked by primarily ground-based radars and optical systems. Recent events in space such as the test of the Chinese anti-satellite weapon in 2007 and the collision between an Iridium and Russian Cosmo satellite have demonstrated the great need to have a more comprehensive awareness of the situation in space. Hence space situational awareness (SSA) has become an increasingly important mission to the Air Force and to the security of the United States. To help meet the need for future leaders knowledgeable about SSA, the Air Force Academy formally stood up the Center for Space Situational Awareness (CSSAR). The goal of the CSSAR is to provide a unique combination of educational operational experience as well as a world-class research capability for hands-on education in SSA. In order to meet this goal, the CSSAR is implementing an array of sensors, operations center, and associated software, and analysis tools. For example we have radar receivers for bi-static returns from the VHF space fence, a network of small aperture telescopes, AFSPC astro standards software, and Joint Mission System software. This paper focuses on the observational capabilities of our telescopes. In general, the preferable method for characterizing a satellite is to obtain a high-resolution image. However, high-resolution images from groundbased telescopes are only achievable if the satellite is large and close in range. Thus small satellites in low-earth orbits and large satellites in geosynchronous orbits are essentially unresolved in the focal plane of a ground-based telescope. Building ever larger telescopes capable of tracking fast enough for satellites at high resolution requires tremendous resources and funding. Cost is one of the reasons we decided to develop a network of small, commercially available telescopes spatially diverse and networked together. We call

    Full Text Available Objective: to understand experiences of parents in a child burning situation during the hospitalization process. Methods: phenomenological research in view of Martin Heidegger, held with seven assisting parents at a pediatrics unit of a general hospital in Montes Claros. The information was obtained by phenomenological interview, containing the question guide: “What does it mean to you being with a son who is suffering with burns?”. Results: during the experience, parents revealed anguish, fear, helplessness, concerns and expectations of “being-in-the-world”. Conclusion: respect, understanding and care from the health team were fundamental for the adaptation and the confrontation demanded by the consequent suffering of the event.

    Prototypical perceptions by therapists have the potential to influence the therapeutic process of assessment. The purpose of this study is to begin to develop an understanding of how prototypes might affect marriage and family therapists' assessments of domestic violence situations. Participants evaluated one of three domestic violence scenarios that were identical in dynamics but different in terms of sexual orientation of the couple (i.e., heterosexual, gay, or lesbian). The most significant finding was that initial assessments of victim and perpetrator identification and power attribution differed depending on the sexual orientation of the couple. The "man as perpetrator, woman as victim" prototypical paradigm for heterosexual domestic violence emerged. In the same-sex scenarios, often "both" partners were perceived to be indicated both as victim and perpetrator.

    In this paper we present an approach to conceiving of, constructing and comparing the concepts developed and used by geographers, environmental scientists and other earth science researchers to help describe, analyze and ultimately understand their subject of study. Our approach is informed by the situations under which concepts are conceived and applied, captures details of their construction, use and evolution and supports their ultimate sharing along with the means for deep exploration of conceptual similarities and differences that may arise among a distributed network of researchers. The intent here is to support different perspectives onto GIS resources that researchers may legitimately take, and to capture and compute with aspects of epistemology, to complement the ontologies that are currently receiving much attention in the GIScience community.

    This project explored the possibility of predicting pilot situational awareness (SA) using human performance modeling techniques for the purpose of evaluating developing cockpit systems. The Improved Performance Research Integration Tool (IMPRINT) was combined with the Adaptive Control of Thought-Rational (ACT-R) cognitive modeling architecture to produce a tool that can model both the discrete tasks of pilots and the cognitive processes associated with SA. The techniques for using this tool to predict SA were demonstrated using the newly developed Aviation Weather Information (AWIN) system. By providing an SA prediction tool to cockpit system designers, cockpit concepts can be assessed early in the design process while providing a cost-effective complement to the traditional pilot-in-the-loop experiments and data collection techniques.

    The Automatic Identification System (AIS) initially designed to ensure maritime security through continuous position reports has been progressively used for many extended objectives. In particular it supports a global monitoring of the maritime domain for various purposes like safety and security but also traffic management, logistics or protection of strategic areas, etc. In this monitoring, data errors, misuse, irregular behaviours at sea, malfeasance mechanisms and bad navigation practices have inevitably emerged either by inattentiveness or voluntary actions in order to circumvent, alter or exploit such a system in the interests of offenders. This paper introduces the AIS system and presents vulnerabilities and data quality assessment for decision making in maritime situational awareness cases. The principles of a novel methodological approach for modelling, analysing and detecting these data errors and falsification are introduced.

    Full Text Available This paper deals with age and sex differences in preferred strategies of conflict resolution in friendship and peer relationships. The study was conducted on the sample of 286 adolescents. Conflict resolution strategies have been investigated by the method of hypothetical conflict situations. For the purposes of this research, we have created an instrument consisting of 20 hypothetical situations, with the following subjects of conflict: breaking the agreement, non-compliance with opinion differences, provocations, dishonesty and stubbornness. Conflict resolution strategies we examined were giving in, withdrawal, competition and problem solving. The results have shown that problem solving is the dominant strategy of adolescents in conflict with friends, while in peer conflicts they more often opt for competition. Age differences are reflected in the fact that older adolescents are more likely to choose problem solving than younger, whereas younger adolescents are more likely to choose a retreat (withdrawal strategy than older. Girls are more prone to choosing problem solving than boys, who, on the other hand, tend to withdraw more than girls. Also, gender of the other person in the conflict is proved to be important - in conflict with male peers, adolescents choose competition to a greater extent and withdraw to a minor extent, compared to when they are in conflict with female peers. The results have practical implications as well. In programs for teaching constructive conflict resolution that are designed for younger adolescents there should be more emphasis on empowerment and training for assertive behaviour. In addition, when teaching about constructive conflict resolution strategies, it is important to consider the gender of adolescents as well as the gender of the person with whom they are in conflict.

  3. Register as the Situational Variety of Language

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available The problem discussed in the article is topical due to the interest of scientists to different types of language variations and especially registers or situational dialects treated by M.A.K. Halliday as use-related varieties of language or varieties used in a particular social setting. As discourse categorization is a very complex problem scholarly consensus has not been reached for the definitions of the term «register». The universal criteria for defining and discriminating registers have not been worked out either. The authors of the article give the review of scientific works devoted to the problem in question especially works by M.A.K. Halliday, R. Quirk, M. Joos, D. Hymes P. Trudgill, E.I. Belyaeva and others and analyze different definitions of the term «register», spectrums of registers and criteria for their discriminating. It enables the authors to come to the conclusion that only registers with the same field (religious, political, business etc. and mode (oral/written, dialogue/monologue can be compared. The difference lies in the sphere of tenor which depends on the degree of formality, distance of power and socio-psychological distance between speakers. The authors believe that it is also necessary to take into account the cooperative/ uncooperative character of conversation and para-verbal and non-verbal components of the speech situation. With this in mind they offer their definition of the register and describe main characteristics of registers in the sphere of oral communication.

    2011-01-01

    We argue that differences between the landscapes of influence situations in Indian and American societies induce Indians to accommodate to others more often than Americans. To investigate cultural differences in situation-scapes, we sampled interpersonal influence situations occurring in India and the United States from both the influencee's (Study 1) and the influencer's (Study 2) perspectives. We found that Indian influence situations were dramatically more likely than U.S. situations to feature other-serving motives and to result in positive consequences for the relationship. Yet Study 3 found that targets of influence felt no less free to decide whether to accommodate in India than the United States, but felt more concerned about the influencer. To investigate the effects of situation-scapes on people's expectations and decisions, we exposed Indian and American participants to descriptions of situations from both societies (with their origins obscured). Study 4 found that both groups of participants expected more positive consequences from accommodation in Indian situations than in American situations. Finally, Study 5 found that both groups decided to accommodate more often in Indian situations than in American situations. At the same time, Indian participants were more likely than Americans to accommodate across all situations, but both groups converged over 100 trials as they were exposed to more and more situations drawn from each other's cultures. We interpret these effects in terms of the default decisions or biases conditioned by people's recently encountered situations. (PsycINFO Database Record (c) 2010 APA, all rights reserved).

    Pasemann, Frank

    2017-01-01

    In the context of the dynamical system approach to cognition and supposing that brains or brain-like systems controlling the behavior of autonomous systems are permanently driven by their sensor signals, the paper approaches the question of neurodynamics in the sensorimotor loop in a purely formal way. This is carefully done by addressing the problem in three steps, using the time-discrete dynamics of standard neural networks and a fiber space representation for better clearness. Furthermore, concepts like meta-transients, parametric stability and dynamical forms are introduced, where meta-transients describe the effect of realistic sensor inputs, parametric stability refers to a class of sensor inputs all generating the "same type" of dynamic behavior, and a dynamical form comprises the corresponding class of parametrized dynamical systems. It is argued that dynamical forms are the essential internal representatives of behavior relevant external situations. Consequently, it is suggested that dynamical forms are the basis for a memory of these situations. Finally, based on the observation that not all brain process have a direct effect on the motor activity, a natural splitting of neurodynamics into vertical (internal) and horizontal (effective) parts is introduced.

    Human judgment and decision-making (JDM) requires an assessment of different choice options. While traditional theories of choice argue that cognitive processes are the main driver to reach a decision, growing evidence highlights the importance of emotion in decision-making. Following these findings, it appears relevant to understand how individuals asses the attractiveness or riskiness of a situation in terms of emotional processes. The following study aims at a better understanding of the psychophysiological mechanisms underlying threat sensitivity by measuring skin conductance responses (SCRs) in passive threat situations. While previous studies demonstrate the role of magnitude on emotional body reactions preceding an outcome, this study focuses on probability. In order to analyze emotional body reactions preceding negative events with varying probability of occurrence, we have our participants play a two-stage card game. The first stage of the card game reveals the probability of receiving an unpleasant electric shock. The second stage applies the electric shock with the previously announced probability. For the analysis, we focus on the time interval between the first and second stage. We observe a linear relation between SCRs in anticipation of receiving an electric shock and shock probability. This finding indicates that SCRs are able to code the likelihood of negative events. We outline how this coding function of SCRs during the anticipation of negative events might add to an understanding of human JDM.

  10. Briefing book on the energy situation in New England

    Energy Technology Data Exchange (ETDEWEB)

    Brainard, J P; Munson, J S; Palmedo, P F

    1976-10-01

    This briefing book is designed to give a concise overview of the facts of the energy situation in New England and of attitudes within the region towards current energy issues. Many of the central problems of U.S. energy policy are manifested in the region in a magnified form. The region entered the period of energy shortages and increasing prices in an economically declining condition. Energy prices were already high in 1970, 30% higher than the rest of the country; the difference increased to 38% by 1974. With essentially no indigenous energy resources, New England is an energy-importing region. For various reasons it is also more dependent on petroleum than other regions of the country and, at the same time, distant from domestic petroleum-producing regions. The result is that over 60% of the fuels it consumes is imported from abroad. Although the future supply of energy to the region is critically dependent on energy-resource policies, policies related for example to coal and oil shale development, the region's concerns cluster around policies and technologies that are perceived to have a more direct impact on its energy welfare. Thus, energy conservation, solar energy, nuclear power, offshore oil development and, in general, the price of energy to the region are paramount issues of concern and debate. Following the Introductory chapter, these issues are discussed in four additional chapters: The Energy Situation in New England; Regional Energy Issues; Energy-Related Institutions; and State Legislation.

    literature review, we advocate a new perspective on SA in terms of sensemaking, also called situated or ecological decision making, where the focus of the investigation is to understand why the decision maker(s) experienced the situation the way they did, or why what they saw made sense to them at the time. This perspective is distinct from the traditional branch of human factors research in the field which focuses more on ergonomics and the transactional relationship between the human operator and the systems. Consistent with our findings from the literature review, we recognized an over-arching need to focus SA research on issues surrounding the concept of shared knowledge; e.g., awareness of what is happening in adjacent areas as well as one’s own area of responsibility. Major findings were: a) Inadequate communication/information sharing is pervasive, b) Information is available, but not used. Many tools and mechanisms exist for operators to build awareness of the physical grid system, yet the transcripts reveal that they still need to call and exchange information with operators of neighboring areas to improve or validate their SA. The specific types of information that they request are quite predictable and, in most cases, cover information that could be available to both operators and reliability coordinators through readily available displays or other data sources, c) Shared Knowledge is Required on Operations/Actions as Well as Physical Status. In an ideal, technologically and organizationally perfect world, every control room and every reliability coordinator may have access to complete data across all regional control areas and yet, there would still be reason for the operators to call each other to gain and improve their SA of power grid operations, and d) Situation Awareness as sensemaking and shared knowledge.

    Background and Purpose: Recent studies have shown a very high importance of relatives in decisions about medical interventions. Therefore, the situation of this group was investigated in the sense of a stocktaking by interviewing the closest relatives of radiotherapy patients. Interviewed Persons and Methods: In a defined span of time (6 weeks), a total of 470 relatives (evaluable: n = 287, 61%) of radiotherapy patients were interviewed by a newly developed questionnaire about their contentment with their inclusion in the therapy course. Further, they gave information about specific needs of relatives as well as proposals for direct improvements in the context of a radiation therapy. Results: In total, the relatives were satisfied with their inclusion in the radiotherapy course and with the patient care. As an example, more than 95% of the relatives agreed with the statement ''Here in the hospital my ill relative is cared for well.'' Nevertheless, direct possibilities for improvements were found in the interdisciplinary information about oncologic topics and in the organization of the therapy course. Conclusion: In the stocktaking the situation of radiotherapy patients' relatives was generally satisfactory. Further improvements for the future can be expected mainly from interdisciplinary cancer centers having the best suppositions to care for the relatives, if necessary. Structures known from palliative care can be used as a model. (orig.)

  19. Reinvigorating the concept of situation in social psychology.

    Reis, Harry T

    2008-11-01

    The concept of situation has a long and venerable history in social psychology. The author argues that recent approaches to the concept of situation have confused certain important elements. Herein, the author proposes that attention to three of these elements will reinvigorate the concept of situation in social psychology: (a) that the analysis of situations should begin with their objective features; (b) that situations should be conceptualized as affordances; and (c) that the interpersonal core of situations, in particular the extent to which they are influenced by relationships, is the proper and most profitable focus for social psychology. These elements are consistent with recent developments in the study of situated social cognition and may help better define social psychology's position within the sciences.

    2008-01-01

    STAY ALIVE is an idea for a safety awareness simulation prototype, powered by gaming technology, that would make safety training enlightening, engaging and fun. Recalling initial instructions and using situational awareness principles, participants would escape a fire by choosing the appropriate door. Escape times would be measured while stressors increased. This presentation describes how STAY ALIVE utilizes first person point of view (PoV), a generic scenario, immersion- and presence-enhancing design, and ease of distribution to provide more people opportunity to realize, review, analyze and practice effective awareness behaviors. The goals for this prototype include facilitating interest in first-person PoV safety training and eliciting further suggestions on prevention technologies.

    Full Text Available This study aimed to analyze Situational Leadership styles adopted by hospital nurses and their association with their personal and professional profile. This is a quantitative and descriptive study and the Hersey and Blanchard leadership model was used with nurses who work in hospitals. Data were collected through sociodemographic questionnaire and the Leadership Effectiveness and Adaptability Description. The more directive leadership style focused on persuasion was the most present. The activity sector showed a significant relation to the leadership style (p=00.1, demonstrating approximation between assistance and leadership profile. Although the population is composed of young group with a short time of performance, the predominance of the Coaching leadership style may limit the creativity and potential of team members for the focus to be focused on the task. Strategies to achieve high levels of maturity, can assist nurses in adopting more flexible leadership practices.

    Intra-organizational competition was examined in relation to ethicality. The effect of a competitor being an in-group versus and out-group member, competitor offering uncorroborated or corroborated information, and the impact of the competitor expressing selfish, pro-group, or pro-organizational level goals were examined. Findings suggest that the way competition is presented has an important influence on how well individuals are able to make sense of an ethically ambiguous situation and render an ethical decision. A main effect for information sharing was found, such that when a competitor offers uncorroborated information participants made less ethical decisions and used pro-ethical reasoning strategies less often. An additional main effect was found suggesting that participants made more ethical decisions when working with an in-group competitor rather than an out-group competitor. Complex interactive effects were also found and discussed suggesting that pro-ethical reasoning strategies may be used less often depending on information corroboration, the competitor's relative group membership status, and the motives expressed by the competitor.

    Across a series of studies, we investigated cultural differences in children's responses to ostracism situations. Working with the children of farmers and herders, we focused on how painful children estimate ostracism to be. Study 1a showed that 4- to 8-year-old children from a socially interdependent farming community estimated ostracism to be less painful than did children from an independent herding community. Study 1b showed that this cultural difference was specific to social pain and did not apply to physical pain. Study 2 replicated the results of Study 1a and showed that individual differences in parents' level of social interdependence mediated the relationship between cultural group and how painful children estimate ostracism to be. Study 3 replicated this effect again and showed that children's tendency to recommend seeking social support following ostracism mediated the relationship between cultural group and the perceived pain of being excluded. Finally, Study 4 investigated cultural differences in moral responses to ostracism and showed that children from the farming community punished an individual who ostracized someone else less harshly than did children from the independent herding community. Thus different economic cultures are associated with striking differences in social interdependence and responses to ostracism from early in development. (PsycINFO Database Record

    Full Text Available Supervision is a dinamic proces which includes changes, acquisitions which have as a result the improving of work conditions, the rise of eficiency, the satisfactions of the employees and the avoiding of professional exhaustion. Nowadays, supervisors are permanently challenged with continuous transformations. The success criteria of the leaders is no longer their capacity to manage teams and unexpected situations, but their real capacity to anticipate and guide their actions. A supervisor does not have the power to fire or hire employees, but he can recommend this to the superior level of management. However, the supervisor can have the following roles: guide, mentor, attorney (for organisation, atorney (for employees. One of the supervisor’s responsabilities is the organisation of the department, but he also has to revise employee’s needs, to set performance standards, to ensure that employees follow the politics, the confidentiality and the procedures of the organisation. Although the purpose to help the employee become efficient seems simple, it can become a frustrating experience. One study about stress factors among supervisors revealed that they confrunt with two kind of problems: their status and the pressure at the work place which affects their performance.

    Full Text Available In some speech communities two distinct varieties of one language are used side by side, each of which serving a different range of social functions. One variety, called High, is used only under formal and public circumstances, while the other one, referred to as Low is used in normal daily-life events. Phonological, semantic and syntactic differences between the two varieties are so drastic that the two varieties are mutually incomprehensible. This sociolinguistic phenomenon is termed "diglossia". It is very common especially in Arabic-speaking countries. One good example is the diglossic situation, held between the Modern Standard Arabic and the Iraqi Colloquial Arabic. The present article aims to illustrate the differences between the two varieties at different linguistics levels, to account for this mutual unintelligibility. To achieve this objective, appropriate data were collected from the two varieties. The linguistic differences were spotted, and categorized according to the Surface Strategy Taxonomy.  The data were analyzed and supported by respective explanations, where necessary. Keywords: Diglossia, Modern Standard Arabic, Iraqi Arabic, High Variety, Low Variety etc.

    2016-09-01

    The Ground-Based Electro-Optical Deep Space Surveillance (GEODSS) System has been in operation since the mid-1980's. While GEODSS has been the Space Surveillance Network's (SSN's) workhorse in terms of deep space surveillance, it has not undergone a significant modernization since the 1990's. This means GEODSS continues to operate under a mostly obsolete, legacy data processing baseline. The System Program Office (SPO) responsible for GEODSS, SMC/SYGO, has a number of advanced Space Situational Awareness (SSA)-related efforts in progress, in the form of innovative optical capabilities, data processing algorithms, and hardware upgrades. Each of these efforts is in various stages of evaluation and acquisition. These advanced capabilities rely upon a modern computing environment in which to integrate, but GEODSS does not have one—yet. The SPO is also executing a Service Life Extension Program (SLEP) to modernize the various subsystems within GEODSS, along with a parallel effort to implement a complete, modern software re-architecture. The goal is to use a modern, service-based architecture to provide expedient integration as well as easier and more sustainable expansion. This presentation will describe these modernization efforts in more detail and discuss how adopting such modern paradigms and practices will help ensure the GEODSS system remains relevant and sustainable far beyond 2027.

  7. Current Economic Situation in Bosnia and Herzegovina

    2011-11-01

    Full Text Available This article provides an overview of the current economic situation in Bosnia and Herzegovina. Beginning in the second half of 2008, macroeconomic conditions in B&H began precipitating a decline in economic activity. While the global financial crisis was among the factors contributing to this decline, it was far from the only factor. Problematic macroeconomic conditions were also a result of B&H’s own structural and political problems, caused largely by the shortcomings of a political entity comprising two autonomous entities. Due to such problems, the governments of B&H turned to the International Monetary Fund for assistance. This article analyzes the effects of the first two “stand by” arrangements made between the IMF and B&H and discusses implications for further, ongoing stand by arrangements made between the IMF and B&H. This paper also examines the lack of unified economic space between The Federation of Bosnia and Herzegovina and The Republic of Srpska, which has resulted not only in ineffective monetary policy but also in different fiscal and taxation systems between the two entities. While various existing analyses claim that B&H has little hope of resolving its economic woes due to its current political and economic structure, this article offers solutions and measures that, if successfully implemented, would lead to more efficient recovery and self-sustainable economic growth.

    This paper summarizes the situation pertinent to treatment via lipoprotein apheresis in the federal state of Saxony, Germany in 2010. In total, 119 predominately male patients were treated in 10 centers; the majority of the patients was older than the mean age of the general population. Several risk factors were present, particularly a familial predisposition and hypertension. All patients had experienced cardiovascular events and the majority was taking statins. Patient data from the University Hospital Carl Gustav Carus in Dresden concurred with data derived from patients treated at nephrological practices. In the mean, patients attended the centers for about 6 years, the majority weekly. LDL cholesterol concentrations prior to apheresis were clearly higher than target levels; apheresis sessions decreased LDL cholesterol by 69%. Lipoprotein(a) levels could be measured in 75 patients and were effectively reduced by lipoprotein apheresis. In Saxony, 29 patients per 1 million inhabitants received lipoprotein apheresis, which is higher than the proportion of patients treated in Germany as a whole. The need for this extracorporeal treatment seems to be much greater than its current utilization. Among the patients only one homozygous patient with familial hypercholesterolemia was observed. Physicians should be actively informed about this therapeutic possibility to reduce the cardiovascular risk efficiently. The introduction of new drugs may alter the position of lipoprotein apheresis within the therapeutic spectrum.

    Drug clinical trial is an important link in the chain of new drug research and development. The results of drug discovery and development directly depend on the extent of standardization of clinical trials. Therefore, improving the quality of drug clinical trials is of great importance, and drug clinical trial institutions play a crucial role in the quality management of drug clinical trials. After years of development, the overall level of drug clinical trials has advanced rapidly in China, and a large number of clinical trials of traditional Chinese medicine have also been carried out. However, there is still a big gap between our country and developed countries. Therefore, for the construction and management of Chinese drug clinical trial institutions, there is still a long way to go. This study aims to analyze the current development of drug clinical trial institutions in China and explore the existing problems from three aspects, including current situations of institutional organization and management, regional and professional distributions, and quality control. And some suggestions are put forward finally, including support of traditional Chinese medicine, introduction of drug-risk management system, and construction of information management.

    It is well reported that expert athletes have refined perceptual-cognitive skills and fixate on more informative areas during representative tasks. These perceptual-cognitive skills are also crucial to performance within the domain of sports officials. We examined the visual scan patterns of elite and sub-elite association football referees while assessing foul play situations. These foul play situations (open play and corner kick situations) were presented on a Tobii T120 Eye Tracking monitor. The elite referees made more accurate decisions and differences in their visual search behaviors were observed. For the open play situations, referees in the elite group spent significantly more time fixating the most informative area of the attacking player (contact zone) and less time fixating the body part that was not involved in the infringement (non-contact zone). Furthermore, the average total fixation time in the contact zone and non-contact zone tended to differ between the elite and sub-elite referees in corner kick situations. In conclusion, elite level referees have learned to discern relevant from less-relevant information in the same way as expert athletes. Findings have implications for the development of perceptual training programs for sport officials.

    Full Text Available Objective to study the decisionmaking process in highriskforviolence situations. Methods formallegal sociological method of hierarchical generalized linear modeling. Results criminological research has favored the rational choice perspective in studying offender decision making. However this theoretical approach does not take into account the complex interplay of situational cognitive emotional and person factors that likely influence criminal decision making. To that end the current study examines decision making in highriskforviolence situations focusing on social information processing and emotional state variables. The current study utilizes a sample of 236 newly incarcerated jailed inmates who provide personal level data and situational reports of violent and avoided violence situations n 466. Scientific novelty the findings for the first time show that several situational social information processing and emotion variables such as intent interpretation goal and response generation are significant predictors of the escalation of violence hence increasing the probability of committing a crime. Practical significance the main provisions and conclusions of the article can be used in scientific and lawenforcement activities when considering the issues of identifying and eliminating the reasons and conditions of crime committing as well as with influencing the individuals in order to prevent crimes or antisocial behavior.

    2006-11-01

    Cooperative formation flight of Unmanned Air Vehicles (UAVs) becomes an attractive research field in recent years. The Simulation Platform of Multiple UAVs is a distributed interactive simulation environment based on High Level Architecture (HLA), which provides a universal simulation platform for the research of multiple UAVs, such as cooperative control, formation flight, mission planning, etc. The platform is composed of several nodes: Mission Control Station (MCS), Formation Control Unit (FCU), UAV Platform, Comprehensive Situation Display, 3-Dimension Display and Simulation Management. As an integral part of the simulation platform, the comprehensive situation sub-system monitors the geography environment and the situation of entities in the simulation. The sub-system is integrated into several nodes of the simulation platform: MCS, FCU and 2-Dimention Situation Display, etc. Considering generalized method and component-based rule, we design and implement comprehensive situation sub-system as well as supporting tool kits. It includes digital map walkthrough environment, map editor with Digital Elevation Model (DEM), bitmap creator, network communication module, situation display module and scenario editor module. Digital map walkthrough environment is a Geographic Information System (GIS) with specific functions, including multiple windows display, map walkthrough and data management. Map editor and bitmap creator create different type of digital map, which is suited for demands of the simulation, and generate terrain data for the UAVs to execute route planning based on DEM. Situation display module displays the situation information of entities in the simulation dynamically and timely. The system is developed without commercial GIS components, and integrated into the environment smoothly.

    To identify situations and thoughts that may precipitate or protect against loneliness experienced by patients with cancer. 
 Qualitative. 
 The hematology/oncology clinic at the Indiana University Melvin and Bren Simon Cancer Center, an outpatient oncology center in Indianapolis. 
 Purposive sample of 15 patients undergoing treatment for multiple myeloma or non-Hodgkin lymphoma. 
 Individual, semistructured qualitative interviews were conducted. Theoretical thematic analysis was used to analyze interview data.
 Factors that appeared to precipitate loneliness included several situations (e.g., physical isolation, social constraints such as criticism) and thoughts (e.g., unmet expectations for visits or questions about health, belief that others do not understand their cancer experience). Several situations (e.g., social support, normal routine) and thoughts (e.g., beliefs that time alone is desirable and that others' discomfort with cancer-related discussions is normative) appeared to protect against loneliness. Certain social situations were loneliness-inducing for some patients and not for others, suggesting that patients' thoughts about their situations, rather than the situations themselves, have the greatest impact on their loneliness. 
 The current study fills gaps in loneliness theory by identifying cancer-related situations and thoughts that patients associate with their loneliness. Consistent with theory, patients reported feeling lonely when they had negative thoughts about their social situations. 
 Findings inform nursing assessment and intervention strategies to incorporate into care plans. For instance, when conducting assessments, nurses should be more attentive to patients' satisfaction with their social environment than actual characteristics of the environment. Normalizing patients' experiences and encouraging positive thoughts about others' behavior may reduce patients' loneliness.

    Bobrinsky, Nicolas

    A new ESA Programme on Space Situational Awareness (SSA) has been approved during the ESA Council at Ministerial level in November 2008. A preparatory phase is in progress, covering the timeframe 2009 -2012. It concentrates on the architectural design of the SSA System, its governance and data policy, as well as on the provision of precursor services based on the federation of existing National and European assets. A continuation of the SSA programme will be proposed at the next Ministerial Council for the years 2012 and onwards. The SSA Preparatory Programme covers three distinct segments, namely: -Space Surveillance and Tracking of artificial objects orbiting the Earth -Space Weather -Near Earth Objects Each of the above segments has a strong relation with Science and is supported by specific RD Programmes at National, EC and ESA levels. In this paper, the scientific aspects of the three SSA Segments are outlined and the following main topics developed: • Space Surveillance: statistical models of the evolution of the space debris population in Earth-bound orbits, study of active mitigation measures, impact analysis, tracking and char-acterisation principles based on radar and optical techniques. • Space Weather: awareness of the natural space environment, detection and forecasting of space weather effects and interferences, analysis of appropriate ground and space-based sensors for the monitoring of the Sun, the solar wind, the radiation belts, the magnetosphere and the ionosphere. • Near Earth Objects (NEOs): methods for determination of physical characteristics of newly discovered objects, study of appropriate sensors based on radar and optical techniques, iden-tification and ranking of collision risks of NEOs with the Earth, study of possible mitigation measures (e.g. Don Quichotes project). The research topics undertaken during the preparatory programme, as well as those foreseen during the next phase, possibly with a strong international cooperation

  16. Cognitive trait anxiety, situational stress, and mental effort predict shifting efficiency: Implications for attentional control theory.

    Science.gov (United States)

    Edwards, Elizabeth J; Edwards, Mark S; Lyvers, Michael

    2015-06-01

    Attentional control theory (ACT) predicts that trait anxiety and situational stress interact to impair performance on tasks that involve attentional shifting. The theory suggests that anxious individuals recruit additional effort to prevent shortfalls in performance effectiveness (accuracy), with deficits becoming evident in processing efficiency (the relationship between accuracy and time taken to perform the task). These assumptions, however, have not been systematically tested. The relationship between cognitive trait anxiety, situational stress, and mental effort in a shifting task (Wisconsin Card Sorting Task) was investigated in 90 participants. Cognitive trait anxiety was operationalized using questionnaire scores, situational stress was manipulated through ego threat instructions, and mental effort was measured using a visual analogue scale. Dependent variables were performance effectiveness (an inverse proportion of perseverative errors) and processing efficiency (an inverse proportion of perseverative errors divided by response time on perseverative error trials). The predictors were not associated with performance effectiveness; however, we observed a significant 3-way interaction on processing efficiency. At higher mental effort (+1 SD), higher cognitive trait anxiety was associated with poorer efficiency independently of situational stress, whereas at lower effort (-1 SD), this relationship was highly significant and most pronounced for those in the high-stress condition. These results are important because they provide the first systematic test of the relationship between trait anxiety, situational stress, and mental effort on shifting performance. The data are also consistent with the notion that effort moderates the relationship between anxiety and shifting efficiency, but not effectiveness.

    Situation awareness describes an individual's perception, comprehension and subsequent projection of what is going on in the environment around them. The concept of situation awareness sits within the group of non-technical skills that include teamwork, communication and managing hierarchical lines of communication. The importance of non-technical skills has been recognised in safety-critical industries such as aviation, the military, nuclear, and oil and gas. However, health care has been slow to embrace the role of non-technical skills such as situation awareness in improving outcomes and minimising the risk of error. This article explores the concept of situation awareness and the cognitive processes involved in maintaining it. In addition, factors that lead to a loss of situation awareness and strategies to improve situation awareness are discussed.

    2014-01-01

    To predict changes of situation awareness (SA) for pilot operating with different display interfaces and tasks, a qualitative analysis and quantitative calculation joint SA model was proposed. Based on the situational awareness model according to the attention allocation built previously, the pilot cognitive process for the situation elements was analyzed according to the ACT-R (Adaptive Control of Thought, Rational) theory, which explained how the SA was produced. To verify the validity of this model, 28 subjects performed an instrument supervision task under different experiment conditions. Situation Awareness Global Assessment Technique (SAGAT), 10-dimensional Situational Awareness Rating Technique (10-D SART), performance measure and eye movement measure were adopted for evaluating SAs under different conditions. Statistical analysis demonstrated that the changing trend of SA calculated by this model was highly correlated with the experimental results. Therefore the situational awareness model can provide a reference for designing new cockpit display interfaces and help reducing human errors.

    Malnutrition in institutionalized elderly is of individual and public concern since it negatively affects health outcome and quality of life and is often preventable. Over the past years several studies have examined the prevalence of malnutrition in institutionalized elderly and reported greatly diverse results. The purpose of the present literature review is to give an overview of the current knowledge about the nutritional situation of institutionalized elderly having specific regard to the prevalence of protein-energy malnutrition and nutrition-related problems. Based on a literature search and additional articles from the files of the authors, observational studies with relatively unselected populations reporting figures for the prevalence of malnutrition and/or the prevalence of nutrition-related problems (e. g. poor appetite, chewing or swallowing problems, eating dependency or poor intake) and published between 1990 and 2006 were considered. Relevant information was extracted and compiled. A total of 42 eligible studies with 41 to 6832 participants were found. BMI was the most frequently used parameter for nutritional assessment with mean values mostly between 21 and 24 kg/m(2). Eight studies applied a cut-off value of 20 kg/m(2) and reported between 10% and 50% low values. Weight loss was reported in 7 studies with prevalence rates between 5 and 41%, reduced serum albumin (malnutrition was observed in 2 to 38% and a risk of malnutrition in 37 to 62%. Nutritional problems were reported in 17 studies, again with great variability between the studies. In physically and mentally capable study populations malnutrition was relatively unfrequent. Prevalence rates were highest in studies with great proportions of disabled and severely impaired residents. It can be concluded that malnutrition is generally widespread in institutionalized elderly. Prevalence rates vary according to the parameters and cut-off values used for nutritional assessment and according to the

    Training is also frequently listed in general applications of SA evaluation. Unfortunately, almost of all methods are either subjective or qualitative, and often time consuming. Since the problems indicate, the core matter of using SA in training is the lack of well-developed or robust measurement tools. Therefore, an intuitive and easy handling SA measurement tool for NPP operators was developed based on the Petri-net and Bayesian inference. Measuring SA using Bayesian theory has been controversy, so sets of simulation training conducted by real NPP operators were video recorded for validation of the tool. There have been many attempts to understand cognitive processes in operators. Describing operator's SA is considered as one of the most plausible ways of such endeavors. Operator's cognitive activities in training can be a barometer of operator's unknown behavior in real situations. Knowing what the operator is thinking is important for better results of upcoming training. To give trainers an intuition that how well operators cope with dynamic situations, the quantitative tool to estimate SA named Corsage was proposed. Corsage gives reasonable clues why the operator behaves in a certain way by showing possible changes in a quantitative and graphical manner. Especially, a graphical comparison between referential information processing flow and operator's real information processing flow can offer trainers a detailed insight. In short, despite the incredulous opinion on measuring human cognition with probability, the result showed a positive view of applicability of Bayesian inference to SA measurement. The next step of the research will be improvement in responsiveness to 'rare but important' information.

    We propose that the domain general process of categorization contributes to the perception of stress. When a situation contains features associated with stressful experiences, it is categorized as stressful. From the perspective of situated cognition, the features used to categorize experiences as stressful are the features typically true of stressful situations. To test this hypothesis, we asked participants to evaluate the perceived stress of 572 imagined situations, and to also evaluate each situation for how much it possessed 19 features potentially associated with stressful situations and their processing (e.g., self-threat, familiarity, visual imagery, outcome certainty). Following variable reduction through factor analysis, a core set of 8 features associated with stressful situations-expectation violation, self-threat, coping efficacy, bodily experience, arousal, negative valence, positive valence, and perseveration-all loaded on a single Core Stress Features factor. In a multilevel model, this factor and an Imagery factor explained 88% of the variance in judgments of perceived stress, with significant random effects reflecting differences in how individual participants categorized stress. These results support the hypothesis that people categorize situations as stressful to the extent that typical features of stressful situations are present. To our knowledge, this is the first attempt to establish a comprehensive set of features that predicts perceived stress.

  7. Enriching Mental Health Mobile Assessment and Intervention with Situation Awareness

    Full Text Available Current mobile devices allow the execution of sophisticated applications with the capacity for identifying the user situation, which can be helpful in treatments of mental disorders. In this paper, we present SituMan, a solution that provides situation awareness to MoodBuster, an ecological momentary assessment and intervention mobile application used to request self-assessments from patients in depression treatments. SituMan has a fuzzy inference engine to identify patient situations using context data gathered from the sensors embedded in mobile devices. Situations are specified jointly by the patient and mental health professional, and they can represent the patient’s daily routine (e.g., “studying”, “at work”, “working out”. MoodBuster requests mental status self-assessments from patients at adequate moments using situation awareness. In addition, SituMan saves and displays patient situations in a summary, delivering them for consultation by mental health professionals. A first experimental evaluation was performed to assess the user satisfaction with the approaches to define and identify situations. This experiment showed that SituMan was well evaluated in both criteria. A second experiment was performed to assess the accuracy of the fuzzy engine to infer situations. Results from the second experiment showed that the fuzzy inference engine has a good accuracy to identify situations.

    Research has shown that the early parent-infant relationship is of critical importance for children's developmental outcomes. While the effect of different settings on mother-infant interactive behavior is well studied, only few researchers systematically examined the effect of situational variables on mother-infant interaction. In the present study the effect of situational variables within the home setting on the quality of mother-infant interaction at 6 months was examined as well as the consistency in the quality of behaviors of mother and infant across these situations. During a home visit 292 mother-infant dyads were videotaped in three different situations (i.e., free play, face-to-face play, and diaper change). Interactive behaviors of mother and infant were assessed with the NICHD global ratings scales. Results showed substantial effects of situation on the interactive behavior of the mother-infant dyad. Despite the observed situational effects maternal sensitivity to non-distress, intrusiveness, stimulation of development, and positive regard and all five infant behavioral scales remained stable across the different situations. Insight into situational effects within the home setting on the quality of mother-infant interactive behavior may assist researchers to make well-informed decisions about measuring the parent-infant interaction in one or more specific situations.

    Jakobson, Gabriel; Buford, John; Lewis, Lundy

    2009-05-01

    Context plays a significant role in situation resolution by intelligent agents (human or machine) by affecting how the situations are recognized, interpreted, acted upon or predicted. Many definitions and formalisms for the notion of context have emerged in various research fields including psychology, economics and computer science (computational linguistics, data management, control theory, artificial intelligence and others). In this paper we examine the role of context in situation management, particularly how to resolve situations that are described by using fuzzy (inexact) relations among their components. We propose a language for describing context sensitive inexact constraints and an algorithm for interpreting relations using inexact (fuzzy) computations.

    1998-12-01

    The present study forms part of the large-scale groundwater flow studies within the SR 97 project. The site of interest is Beberg which is based on data from the Finnsjoen site. To understand the groundwater flow and salinity at present it is necessary to consider the history of the Finnsjoen site over the last few thousand years. A numerical approach is developed to model a situation of transient variable density flow on a regional scale. The model is considered a reasonable representation of the real situation at the site, since it is consistent with the current conceptual understanding of the site and predictions of salinity are in broad agreement with field observations. The effects of post-glacial uplift on the hydrogeological conditions are considered. It is assumed that about 9,000-4,000 years BP the rock was completely infiltrated by saline groundwaters during the periods when the Yoldia and Litorina Seas covered the Finnsjoen area. The model represents the interval from the end of this period up to the present day. During which time the recharge of fresh water in the form of rainfall flushed or displaced saline water from the near-surface. Many variants on the basis conceptual model are considered both to calibrate the model against field data and to quantify the sensitivities of groundwater pathways. The present study shows that: Salinity and transient processes are very important in determining groundwater pathways in the deep rock. Salinity drives flow downwards increasing the length of pathways and groundwater travel times. A high contrast in hydraulic conductivity between major structures and the rock mass results in the fracture zones being the dominant flow paths, in particular Zone 1 and Imundbo. There are two distinct flow paths. In the east of the hypothetical repository the path is short along Zone 1, for the west the path is longer through the rock mass. Fracture zones are flushed of salt on a time-scale of 10-100 years. For the rock mass it

  6. Situated health promotion: reflections on implementing situated learning approaches in health promotion.

    2010-07-01

    Handing down health knowledge and behavior patterns is a main objective of health promotion. Often, interventions do not bring about the intended change of behavior. This could be due, among other things, to the fact that the majority of intervention programs are not based on principles of instructional design to bridge the gap between knowledge and action. A situated design of health promotion measures is to be considered particularly suitable. That accounts for the fact that the acquisition and application of knowledge is an active construction process on the part of the individuals involved, and one that includes the possibility to improve the quality of learning processes in the area of health promotion, and thus increases the probability that acquired knowledge can be applied in real situations. In the context of the problem that most health promotion interventions frequently do not show the desired permanent behavioral changes of the participating individuals, from a pedagogical perspective, it is crucial that current didactic-methodological principles be taken into account. This, too, should be taken into account in connection with an empirical analysis of the reflections in this article. In the following paper, various suggestions for implementation are explained and discussed.

    Full Text Available OBJECTIVE: This study modeled win and lose trials in a simple gambling task to examine the effect of entire win-lose situations (WIN, LOSS, or TIE on single win/lose trials and related neural underpinnings. METHODS: The behavior responses and brain activities of 17 participants were recorded by an MRI scanner while they performed a gambling task. Different conditions were compared to determine the effect of the task on the behavior and brain activity of the participants. Correlations between brain activity and behavior were calculated to support the imaging results. RESULTS: In win trials, LOSS caused less intense posterior cingulate activity than TIE. In lose trials, LOSS caused more intense activity in the right superior temporal gyrus, bilateral superior frontal gyrus, bilateral anterior cingulate, bilateral insula cortex, and left orbitofrontal cortex than WIN and TIE. CONCLUSIONS: The experiences of the participants in win trials showed great similarity among different win-lose situations. However, the brain activity and behavior responses of the participants in lose trials indicated that they experienced stronger negative emotion in LOSS. The participants also showed an increased desire to win in LOSS than in WIN or TIE conditions.

    In a large and heavily networked specialty like gynaecology it is a particular challenge with regard to future status to achieve excellent patient care, research and teaching. At the same time not only hospitals but also research facilities are experiencing increasing pressure from performance and competition sides in terms of survival and further development on the clinical, scientific and economic fronts. The numerous changes, including paradigm shifts, in medicine, society, the health-care system and scientific innovations present new challenges to the specialty. This leads to questions about priority, problem areas and weaknesses as well as to new opportunities for the field and the overall question if it will be possible to meet the paradigm shifts and problems by the creation of new structures. In the light of the need for and the potential of design measures, this article presents a SWOT analysis of the specialty's situation as a whole and in particular for gynaecology in German universities. One sees additional demands that add up to an expansion of the tasks. At the same time the shortage of new recruits becomes apparent. A broadening of the perspectives on women's health and individualised medicine come into focus. Partial solutions include new supporting structures, capacity measurements as well as even structural options. In particular, the department structure, that is common abroad, opens an opportunity for specialisation while maintaining unity for a broader further training and strengthened research. Chances and strengths of the specialty are especially effective in coordinated and concerted activities.

    Craig, Carol

    2012-01-01

    In aviation, there is currently a lack of accurate and timely situational information, specifically weather data, which is essential when dealing with the unpredictable complexities that can arise while flying. For example, weather conditions that require immediate evasive action by the flight crew, such as isolated heavy rain, micro bursts, and atmospheric turbulence, require that the flight crew receive near real-time and precise information about the type, position, and intensity of those conditions. Human factors issues arise in considering how to display the various sources of weather information to the users of that information and how to integrate this display into the existing environment. In designing weather information display systems, it is necessary to meet the demands of different users, which requires an examination of the way in which the users process and use weather information. Using Human Centered Design methodologies and concepts will result in a safer, more efficient and more intuitive solution. Specific goals of this approach include 1) Enabling better fuel planning; 2) Allowing better divert strategies; 3) Ensuring pilots, navigators, dispatchers and mission planners are referencing weather from the same sources; 4) Improving aircrew awareness of aviation hazards such as turbulence, icing, hail and convective activity; 5) Addressing inconsistent availability of hazard forecasts outside the United States Air Defense Identification Zone (ADIZ); and 6) Promoting goal driven approaches versus event driven (prediction).

    Despite scientific advances, corneal grafting is still in a crucial situation in France in 1999. Over the last 3 years, the number of corneal grafts (2 903 in 1996, 3 213 in 1997, and 4 053 in 1998) has been insufficient to satisfy estimated needs (8 041 in 1996, 8 303 in 1997, 7 400 in 1998). The consequences are waiting lists, long time on waiting lists, and regional differences. This situation results more from difficulties in the cornea procurement system than from limited numbers of potential donors or restricted selection criteria. Progress will depend greatly on structural changes.

    In this paper, we propose a distributed predator aware situation assessment system (PORTENT) to model and detect potential events occurring within an uncertain environment. PORTENT draws inspiration from how the mammalian brain detects and makes rational decisions through assessing fragmented signals of threat, within uncertainty, at different speeds. PORTENT represents the faster system using standard signal detection theory and the slower more accurate system as the integration of sensory data over time, until a certain level of confidence is reached. We also consider strategies to how both these systems could be combined optimally, to enhance PORTENT situation assessment performance. Our experimental simulations to verify the PORTENT concept demonstrates the effectiveness of our approach.

    With rapid development of vocational education,part-time teachers’team has become an important part of higher voca-tional schools,but various problems emerge during practice. Because of the special background of rail transportation professional,part-time teachers’employing channel is restricted;the overall quality is not high owing to their low educational level and technical post title. At the same time,lack of educational theory leads to lack of class controlling ability and difficulty of teaching quality control for part-time teachers due to their contradiction between full-time j obs and part-time j obs. Relative countermeasures contain strengthening policy leading,deepening college-enterprise co-operation and improving management system.%随着职业教育的快速发展,兼职教师队伍日益成为高职院校师资队伍的重要组成部分,但在实践中也产生不少问题。高职轨道交通类专业更因其特殊的行业背景,兼职教师聘用渠道受限,学历和职称总体不高,整体质量偏低,同时,由于缺少教育理论素养,课堂把控能力不足,且专兼职矛盾难以调和,教学质量监控困难,应当从加强政策引导,深化校企合作,完善管理制度几个方面着力加以解决。

    2014-02-01

    Full Text Available Placenta percreta, the most severe form of placenta accreta, is a rare pregnancy disorder in which the placenta penetrates the uterine myometrium and serosa and can invade the surrounding organs. It is a potentially life-threatening condition with risk of severe maternal morbidity and mortality. Although recognized obstetric risk factors allow the identification of most cases during the prenatal period, diagnosis is occasionally made at the time of delivery. Both sonography and MRI have fairly good sensitivity for prenatal diagnosis of placenta accreta. Prenatal diagnosis allows management of these patients in specialized tertiary centers, where a multidisciplinary approach will improve the outcome. Even in undiagnosed cases discovered at the time of delivery involving a team of anesthesiologist, obstetrician, urologist, neonatologist, and blood bank officer is needed for successful management of these patients. In this report we present the case of a primigravida with no known risk factors who was diagnosed to have placenta percreta at the time of caesarean delivery.

  19. Deinstitutionalising school science: Implications of a strong view of situated cognition

    Science.gov (United States)

    Roth, Wolff-Michael; McGinn, Michelle K.

    1997-12-01

    Psychological models of learning have been shaped by information processing models for four decades. These models have led to teaching models based on information transfer from teachers to students. However, recent research in many fields shows that information processing models do not account for much of human competence in everyday scientific and lay contexts. At the same time, situated cognition models have been developed that better account for competence in widely differing situations. The implications of situated cognition are rather different from those of information processing. Teaching and learning are no longer conceived simply in terms of information transfer but as increasing participation in everyday practices. Conceiving of science learning as a trajectory of increasing participation asks educators to rethink the purpose of science education from preparing scientists to preparing citizens to participate in public enactments of science, and this entails deinstitutionalising school science to take science beyond the classroom walls.

    2017-01-27

    This study explores the nature and outcome of violent incidents experienced by child, adolescent, adult, and elderly victims. Data from the National Incident-Based Reporting System (NIBRS) are used to determine whether there are differences in the situational characteristics—including location, time of day, weapons, and the victim–offender relationship—of violent victimization experiences across the 4 age groups, including whether situational characteristics influence the likelihood of victim injury. Results indicate that victim injury is most prevalent among adult victims and that the situational characteristics of violent incidents vary by victim age, as do the correlates of victim injury. These findings suggest that of the nature of violent victimization should be examined within the context of victim age, and supports research by scholars who have proposed a model of developmental victimology to identify age-specific victimization patterns.

    Lankford's book makes the important point that analyses of suicide terrorists often commit the error of overestimating the importance of situational causes of behavior and underestimating dispositional causes, such as underlying pathology. Personality and individual differences are important; suicide terrorists are not ordinary people driven by situational pressures. However, citation of empirical evidence is haphazard; the scholarly argument is not well-developed.

    Lebois, Lauren A.M.; Hertzog, Christopher; Slavich, George M.; Barrett, Lisa Feldman; Barsalou, Lawrence W.

    2016-01-01

    We propose that the domain general process of categorization contributes to the perception of stress. When a situation contains features associated with stressful experiences, it is categorized as stressful. From the perspective of situated cognition, the features used to categorize experiences as stressful are the features typically true of stressful situations. To test this hypothesis, we asked participants to evaluate the perceived stress of 572 imagined situations, and to also evaluate each situation for how much it possessed 19 features potentially associated with stressful situations and their processing (e.g., self-threat, familiarity, visual imagery, outcome certainty). Following variable reduction through factor analysis, a core set of 8 features associated with stressful situations—expectation violation, self-threat, coping efficacy, bodily experience, arousal, negative valence, positive valence, and perseveration—all loaded on a single Core Stress Features factor. In a multilevel model, this factor and an Imagery factor explained 88% of the variance in judgments of perceived stress, with significant random effects reflecting differences in how individual participants categorized stress. These results support the hypothesis that people categorize situations as stressful to the extent that typical features of stressful situations are present. To our knowledge, this is the first attempt to establish a comprehensive set of features that predicts perceived stress. PMID:27288834

    2016-08-01

    Attentional control theory (ACT) describes the mechanisms associated with the relationship between anxiety and cognitive performance. We investigated the relationship between cognitive trait anxiety, situational stress and mental effort on phonological performance using a simple (forward-) and complex (backward-) word span task. Ninety undergraduate students participated in the study. Predictor variables were cognitive trait anxiety, indexed using questionnaire scores; situational stress, manipulated using ego threat instructions; and perceived level of mental effort, measured using a visual analogue scale. Criterion variables (a) performance effectiveness (accuracy) and (b) processing efficiency (accuracy divided by response time) were analyzed in separate multiple moderated-regression analyses. The results revealed (a) no relationship between the predictors and performance effectiveness, and (b) a significant 3-way interaction on processing efficiency for both the simple and complex tasks, such that at higher effort, trait anxiety and situational stress did not predict processing efficiency, whereas at lower effort, higher trait anxiety was associated with lower efficiency at high situational stress, but not at low situational stress. Our results were in full support of the assumptions of ACT and implications for future research are discussed. (PsycINFO Database Record

The area's documents and reports of meetings were read from 2004 to 2013 Medicine III Capes as well as reports and evaluation form of each Postgraduate Program (PPG) of the area and the sub-page of the area from the Capes website. The data relating to the evaluation process, the assessment form and faculty, student and scientific production data of all of Post-Graduate Programs of Medicine III were computed and analyzed. From these data were detected the challenges of the area for the next four years (2013-2016). Among the 3,806 PPG, Medicine III had 41 PPG during last triennial evaluation and progressed from 18% to 43% of PPG very good or more concept (triennium 2001-2003 and 2010-2012). Most PPG were located in the South-East region (32), three in the South and two in the North-East. There was no PPG in North or Central-West regions. In 2013 and 2014 there were four approved Professional Master Degree Programs and one Master (M) and Doctorate (PhD). The average of permanent professors was 558 teachers with about three students/professor. The number of PhD graduates has increased as well as the reason PhD/MD. The proportion of in high impact periodicals (A1, A2, B1 and B2) jumped from 30% to 50% demonstrating positive community response to the policy area. The challenges identified were: decrease regional asymmetry, increase the number of masters and doctors of excellence, reassessment of Brazilian journals, stimulate and set internationalization indicators, including post-doctors and definition of its indicators, the PPG nucleation analysis, PPG 3x3, include primary and secondary education, professional master and indicators of technological scientific production and solidarity.

    2012-01-01

    Music is a stimulus capable of triggering an array of basic and complex emotions. We investigated whether and how individuals employ music to induce specific emotional states in everyday situations for the purpose of emotion regulation. Furthermore, we wanted to examine whether specific emotion-regulation styles influence music selection in specific situations. Participants indicated how likely it would be that they would want to listen to various pieces of music (which are known to elicit specific emotions) in various emotional situations. Data analyses by means of non-metric multidimensional scaling revealed a clear preference for pieces of music that were emotionally congruent with an emotional situation. In addition, we found that specific emotion-regulation styles might influence the selection of pieces of music characterised by specific emotions. Our findings demonstrate emotion-congruent music selection and highlight the important role of specific emotion-regulation styles in the selection of music in everyday situations.

    Science.gov (United States)

    Adams, Marilyn J.; Pew, Richard W.

    1990-01-01

    A cognitive theory is presented that has relevance for the definition and assessment of situational awareness in the cockpit. The theory asserts that maintenance of situation awareness is a constructive process that demands mental resources in competition with ongoing task performance. Implications of this perspective for assessing and improving situational awareness are discussed. It is concluded that the goal of inserting advanced technology into any system is that it results in an increase in the effectiveness, timeliness, and safety with which the system's activities can be accomplished. The inherent difficulties of the multitask situation are very often compounded by the introduction of automation. To maximize situational awareness, the dynamics and capabilities of such technologies must be designed with thorough respect for the dynamics and capabilities of human information-processing.

    Costabile, Kristi A

    2016-05-01

    The present investigation examined how three salient features of narrative thinking (situation model construction, linguistic concreteness, and perspective-taking) influenced the social inference process. Results of four experiments indicated that compared with those given other objectives, perceivers given narrative objectives were: (a) more likely to make situation rather than trait attributions for observed behaviors (Experiment 1), (b) less likely to make implicit trait inferences (Experiment 2), and (c) less likely to rely on behavior valence when making evaluative judgments (Experiment 4). Linguistic analyses indicated that narrative construction consistently entailed the creation of situation models of events and linguistic concreteness, but only situation model creation mediated the relationship between narrative and inferences. Experiment 3 confirmed the mediating role of situation models: Perceivers with narrative objectives made trait inferences only when behaviors were inconsistent with contextual information. The role of these core narrative features on social perceptions is discussed.
