Full Text Available In order to address the flight delays and risks associated with the forecasted increase in air traffic, there is a need to increase the capacity of air traffic management systems. This should be based on objective measurements of traffic situation complexity. In current air traffic complexity research, no simple means is available to integrate airspace and traffic flow characteristics. In this paper, we propose a new approach for the measurement of air traffic situation complexity. This approach considers the effects of both airspace and traffic flow and objectively quantifies air traffic situation complexity. Considering the aircraft, waypoints, and airways as nodes, and the complexity relationships among these nodes as edges, a dynamic weighted network is constructed. Air traffic situation complexity is defined as the sum of the weights of all edges in the network, and the relationships of complexity with some commonly used indices are statistically analyzed. The results indicate that the new complexity index is more accurate than traffic count and reflects the number of trajectory changes as well as the high-risk situations. Additionally, analysis of potential applications reveals that this new index contributes to achieving complexity-based management, which represents an efficient method for increasing airspace system capacity.

Full Text Available This paper analyzes the representations of the major educational process participants (students, teachers and representatives of the school administration concerning the various elements of the socio-psychological situation in the educational institution. We assumed that the substantive characteristics of socio-psychological situation are reflected in the representations of the major participants of the educational process, which can help to define the degree of homogeneity of representations in students and teachers, as well as the uniqueness of socio-psychological situation in an educational institution. We describe the progress and the results of research conducted in Moscow on the basis of state educational institutions of various profiles (gymnasium with intensive study of English secondary school with ethno-cultural component, which was attended by 308 people, 235 of whom were students, and 73 were teachers and representatives of the school administration. We reveal the features of representation of different participants of the educational process about such elements of socio-psychological situation as leadership style, the type of organizational culture and the parameters of social and psychological climate in the educational institution. We describe significant differences in the expression of the elements of social and psychological situation in educational institutions of various types.

In this study, it was revealed that the designed worksheets were feasible to collect HRA data, especially in abnormal situations. The defined taxonomy of UAs was unambiguous to distinguish actions of operators and quantify the probabilities. It is widely recognized that reliability of operators are critical to complex socio-technical systems. For this reason, human reliability analysis (HRA), which aims to identify unsafe actions (UAs) that contribute to risks of the systems and assess the failure rates of the actions, has been conducted. Although many techniques of HRA have been developed and used in many years, many reports indicated lack of database for supporting empirical bases of HRA methods. Thus, there have been recent efforts to collect data about human reliability from plant experience, simulator experiment or qualification, and laboratory experiments. As one of these efforts, KAERI also established a guideline to collect information about human reliability and performance shaping factors from simulators. This guideline particularly presented a set of worksheets that allows comprehensively gathering objectively observable information in simulations of emergency situations. This paper reports the process and preliminary results of the data collection from the simulations of abnormal situations based on the developed worksheets in KAERI database guideline. We analyzed operator behaviors of the sixteen experiments for the two kinds of abnormal situations: RCP (reactor coolant pump) cyclone filter blockage and CDP (condensate pump) valve stuck. The UAs of operators were identified and quantified. Because the number of simulations was limited and data of various situations will be obtained continuously, it is uncertain to conclude the resulted probabilities. Based on the worksheet, operator behaviors in many different kinds of scenarios will be analyzed and the relations between human reliabilities and the observed factors will be also investigated.

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.

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.

Education is a complex process that involves the individual in the course of his entire life and leads to the maturation and the overall development of his personality. The educational process involves the complete growth of each and completes the infinite possibilities that every child has potential since birth. Education also is a necessity for the human being, as only adequate environmental stimulation causes the mental processes to begin. In fact, the higher intellectual functions, such as language, thought, memory, emerge only from social and educational experiences of the child. The educational surgery creates experiences and learning that allow the person to change by improving the efficiency of synaptic connections. Clinical pedagogy has developed in Italy in the last decades of the twentieth century with the aim of research and experimenting educational purposes suitable for different situations in order to provide each subject with appropriate development opportunities. Clinical pedagogical support is offered in the form of artistic or bodily activities and represents for the individual a positive environment that allows the development of different brain areas and the potential inherent in them. The various methods are suitable for any situation of existential discomfort, which are understood as moments of personal growth.

Do the coach and athlete have the same "picture" of the situation? Distributed Situation Awareness in an elite sport context.

Macquet, Anne-Claire; Stanton, Neville A

2014-05-01

Athletes and their coach interpret the training situations differently and this can have important implications for the development of an elite athlete's performance. It is argued that, from a schema-theoretic perspective, the difference in these interpretations needs to be better understood. A post-performance, self-confrontation, interview was conducted with a number of athletes and their coaches. The interviews revealed differences between the athlete and their coach in the information they are aware of. In comparison with athletes, coaches more frequently compared the phenotype with genotype schemata rather than just describing the phenotype schemata. Results suggest SA information elements showed some common ground but also revealed some important differences between the athlete and coach. The awareness was directed externally towards the environment and internally, towards the individual, depending on his/her role. The investigation showed that the schemata used to 'frame' the information elements were different, but compatible, between athlete and coach.

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

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 (c) 2016 APA, all rights reserved).

Modeling of Communication in a Computational Situation Assessment Model

International Nuclear Information System (INIS)

Lee, Hyun Chul; Seong, Poong Hyun

2009-01-01

Operators in nuclear power plants have to acquire information from human system interfaces (HSIs) and the environment in order to create, update, and confirm their understanding of a plant state, or situation awareness, because failures of situation assessment may result in wrong decisions for process control and finally errors of commission in nuclear power plants. Quantitative or prescriptive models to predict operator's situation assessment in a situation, the results of situation assessment, provide many benefits such as HSI design solutions, human performance data, and human reliability. Unfortunately, a few computational situation assessment models for NPP operators have been proposed and those insufficiently embed human cognitive characteristics. Thus we proposed a new computational situation assessment model of nuclear power plant operators. The proposed model incorporating significant cognitive factors uses a Bayesian belief network (BBN) as model architecture. It is believed that communication between nuclear power plant operators affects operators' situation assessment and its result, situation awareness. We tried to verify that the proposed model represent the effects of communication on situation assessment. As the result, the proposed model succeeded in representing the operators' behavior and this paper shows the details

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. We propose you of to know more about it in this file. (N.C.)

2017-05-15

Many studies suggest that animals exhibit lateralized behaviors during aversive situations, and almost all animals exhibit right hemisphere-dominant behaviors associated with fear or anxiety. However, which brain structure in each hemisphere underlies such lateralized function is unclear. In this study, we focused on the hippocampus and investigated the effects of bilateral and unilateral lesions of the ventral hippocampus (VH) on anxiety-like behavior using the successive alleys test. We also examined the expression of c-fos in the VH, which was induced by an aversive situation. Results revealed that consistent right VH dominance trended with the anxiety level. Weaker anxiety induced both right and left VH functions, whereas stronger anxiety induced right VH function. From these results, we conclude that animals are able to adaptively regulate their behaviors to avoid aversive stimuli by changing the functional dominance of their left and right VH.

The cultural dimension of tightness-looseness: An analysis of situational constraint in Estonia and Greece.

Realo, Anu; Linnamägi, Karmen; Gelfand, Michele J

2015-06-01

The importance of tightness-looseness as a dimension that explains a considerable amount of variance between cultures was demonstrated by Gelfand et al. (2011). Tight nations have many strong norms and a low tolerance of deviant behaviour, whereas loose nations have weak social norms and a high tolerance of deviant behaviour. The main aim of the current studies was to examine situational constraint in Estonia and Greece: that is, how the cultural dimension of tightness-looseness is manifested in everyday situations in those two countries. The findings of a questionnaire study (Study 1) suggested that, in general, there is higher constraint across everyday situations in Greece than in Estonia, but situational constraint in Greece is especially strong in school and organisational settings where people have hierarchically structured roles. The results of an observational study (Study 2) revealed a relatively high agreement between appropriateness of certain behaviours as judged by the respondents in Study 1 and the frequencies of observed behaviours in the two countries. Our findings suggest that the strength of situations may substantially vary both within and across cultures, and that the attitudes of the members about situational strength in their respective cultures are in concordance with observations of situations by neutral observers in how people in general behave in their culture. © 2014 International Union of Psychological Science.

Alcohol-related memory associations in positive and negative affect situations: drinking motives, working memory capacity, and prospective drinking.

Salemink, Elske; Wiers, Reinout W

2014-03-01

Although studies on explicit alcohol cognitions have identified positive and negative reinforcing drinking motives that are differentially related to drinking indices, such a distinction has received less attention in studies on implicit cognitions. An alcohol-related Word-Sentence Association Task was used to assess implicit alcohol-related memory associations in positive and negative affect situations in 92 participants. Results revealed that enhancement motives were specifically associated with the endorsement of alcohol words in positive affect situations and coping motives were associated with the endorsement of alcohol words in negative affect situations. Furthermore, alcohol associations in positive affect situations predicted prospective alcohol use and number of binges, depending on levels of working memory capacity. The current findings shed more light on the underpinnings of alcohol use and suggest that implicit memory processes and working memory capacity might be important targets for intervention.

Relationship among achievement goal orientations and multidimensional situational motivation in physical education.

Standage, Martyn; Treasure, Darren C

2002-03-01

Contemporary research suggests that task and ego achievement goal orientations affect students' intrinsic motivation in physical education. This research has assessed intrinsic motivation as a unidimensional contruct, however, which is inconsistent with the more contemporary postulates of self-determination theory (Deci & Ryan, 1985, 1991) which states that intrinsic motivation is only one type of motivation. To date, research has not addressed whether different types of motivation at the situational level are influenced by the proneness to adopt task or ego involvement. To examine the relationship between achievement goal orientations and multidimensional situational motivation in PE. Middle school children (182 male, 136 female; M age = 13.2 years). Responded to questionnaires assessing their dispositional goal orientation (POSQ; Roberts, Treasure, & Balague, 1998) and situational motivation (SIMS; Guay, Vallerand, & Blanchard, 2000) in PE. Task orientation was found to be positively associated with more self-determined types of situational motivation. Ego orientation was weakly related to less self-determined motivation. An extreme group split was conducted to create four goal groups and goal profile analyses conducted. A significant MANOVA was followed by univariate analyses, post hoc comparisons, and calculated effect sizes, which revealed that groups high in task orientation reported more motivationally adaptive responses than groups low in task orientation. The results suggest that a high level of task orientation singularly or in combination with ego orientation fosters self-determined situational motivation in the context of PE.

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.

The Process Overview Measure is a query-based measure developed to assess operator situation awareness (SA) from monitoring process plants. A companion paper describes how the measure has been developed according to process plant properties and operator cognitive work. The Process Overview Measure demonstrated practicality, sensitivity, validity and reliability in two full-scope simulator experiments investigating dramatically different operational concepts. Practicality was assessed based on qualitative feedback of participants and researchers. The Process Overview Measure demonstrated sensitivity and validity by revealing significant effects of experimental manipulations that corroborated with other empirical results. The measure also demonstrated adequate inter-rater reliability and practicality for measuring SA in full-scope simulator settings based on data collected on process experts. Thus, full-scope simulator studies can employ the Process Overview Measure to reveal the impact of new control room technology and operational concepts on monitoring process plants. Practitioner Summary: The Process Overview Measure is a query-based measure that demonstrated practicality, sensitivity, validity and reliability for assessing operator situation awareness (SA) from monitoring process plants in representative settings.

Great efforts have been made in the frame of the national and international research programs to get complete data on the radioactive releases, environmental contamination and radiological situation resulted from the Chernobyl accident. Beginning from the first publication (IAEA meeting, August 1986) these data have been considerably improved and added. The most important change of them with their influence on the decision making in the mitigation activity and the current situation is described and analyzed. The national and international regulatory documents at the moment of the accident were neither complete nor perfect in some necessary aspects especially in respect to the countermeasures at the intermediate and long-term phases. New documents have been worked out during the intervention activity. From 1986 series of documents were developed on the national and international levels. These documents are considered and analyzed in the context of their practical implementation and by the modern experience and research results. The history of countermeasures adopted on the different intervention phases are described. These documents mainly establish intervention levels in terms of averted doses and regulate only radiation protection. They don't content any intervention levels in terms of residual doses and risk, which are necessary for regulation of social and health protection of population suffered from the accident. Other restriction for the optimal regulation comes from use of the effective dose for establishing intervention levels. These and other respective aspects are discussed

Situation-based social anxiety enhances the neural processing of faces: evidence from an intergroup context

Science.gov (United States)

Ofan, Renana H.; Rubin, Nava

2014-01-01

Social anxiety is the intense fear of negative evaluation by others, and it emerges uniquely from a social situation. Given its social origin, we asked whether an anxiety-inducing social situation could enhance the processing of faces linked to the situational threat. While past research has focused on how individual differences in social anxiety relate to face processing, we tested the effect of manipulated social anxiety in the context of anxiety about appearing racially prejudiced in front of a peer. Visual processing of faces was indexed by the N170 component of the event-related potential. Participants viewed faces of Black and White males, along with nonfaces, either in private or while being monitored by the experimenter for signs of prejudice in a ‘public’ condition. Results revealed a difference in the N170 response to Black and Whites faces that emerged only in the public condition and only among participants high in dispositional social anxiety. These results provide new evidence that anxiety arising from the social situation modulates the earliest stages of face processing in a way that is specific to a social threat, and they shed new light on how anxiety effects on perception may contribute to the regulation of intergroup responses.

To implement and evaluate the effect of using the Person-Centred Situational Leadership Framework to develop person-centred care within nursing homes. Many models of nursing leadership have been developed internationally in recent years but do not fit with the emergent complex philosophy of nursing home care. This study develops the Person-Centred Situational Leadership Framework that supports this philosophy. It forms the theoretical basis of the action research study described in this article. This was a complex action research study using the following multiple methods: nonparticipatory observation using the Workplace Culture Critical Analysis Tool (n = 30); critical and reflective dialogues with participants (n = 39) at time 1 (beginning of study), time 2 (end of study) and time 3 (6 months after study had ended); narratives from residents at time 1 and time 2 (n = 8); focus groups with staff at time 2 (n = 12) and reflective field notes. Different approaches to analyse the data were adopted for the different data sources, and the overall results of the thematic analysis were brought together using cognitive mapping. The Person-Centred Situational Leadership Framework captures seven core attributes of the leader that facilitate person-centredness in others: relating to the essence of being; harmonising actions with the vision; balancing concern for compliance with concern for person-centredness; connecting with the other person in the instant; intentionally enthusing the other person to act; listening to the other person with the heart; and unifying through collaboration, appreciation and trust. This study led to a theoretical contribution in relation to the Person-Centred Practice Framework. It makes an important key contribution internationally to the gap in knowledge about leadership in residential care facilities for older people. The findings can be seen to have significant applicability internationally, across other care settings and contexts. �

Necessity of supporting situation understanding to prevent over-trust in automation

International Nuclear Information System (INIS)

Itoh, Makoto

2010-01-01

It is necessary to clarify how a human operator comes to expect that an automation will perform a task successfully even beyond the limit of the automation. This paper proposes a way of modeling trust in automation by which it is possible to discuss how an operator's trust in automation becomes over-trust. On the basis of the model, an experiment using a micro world was conducted to examine whether the range of user's expectation per se surpasses the limit of the capability of the automation. The results revealed that informing the human operator of the functional limit of capability of automation without giving an appropriate reason was effective but not perfect for avoiding human operator's over trust. It was also shown that the understanding of the automation's limitation can be changed through experiences due to confusion about the situation, therefore, it is necessary to support adequate situation understanding of the human operator in order to prevent over-trust in automation.

Full Text Available In order to reflect the situation of network security assessment performance fully and accurately, a new network security situation awareness model based on information fusion was proposed. Network security situation is the result of fusion three aspects evaluation. 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.

2016-05-01

People presumably choose and create their daily environments according to their personality. Prior research shows that, for example, more extraverted people engage more often in social situations, and more conscientious people engage more often in work-related activities compared with less extraverted or less conscientious people, respectively. The current study examined such personality-situation transactions in people's daily life. Based on the assumption that older people know themselves and their personality better than younger people, we investigated whether momentary and proximate personality-situation associations (i.e., changing from 1 type of situation into another) increase with older age. Three-hundred and 78 people aged 14 to 82 years described their Big Five traits and took part in a 3-week experience-sampling phase. Using mobile-phone based assessments in daily life, participants reported on average 55 times on their momentary situation. Multilevel modeling results showed that personality-situation associations varied with the age of participants. Some of the "established" personality-situation associations, such as for extraversion and time spent with friends or conscientiousness and time spent with work activities, were only observed in adolescence and young adulthood. In contrast, other personality-situation associations appeared only in late adulthood, such as for openness and time spent with friends. Yet most personality-situation associations did not vary significantly with people's age. In addition, personality traits predicted maintaining or entering personality-congruent situations. The latter results point to the active role of personality in shaping one's environment. The findings imply that some personality-situation transactions may be largely similarly across the life span.

Full Text Available The purpose of the study is to reveal the music listening situation of the students at the Faculty of Fine Arts of Dokuz Eylül University, the music genres that they listen to and the relationship between them. It is also investigated whether the music listening situation determines the music training of the students or also makes significant difference among students according to their genders. The music listening situation scale developed as five-point Likert type and the frequency of listening to music scales were used as for data collection tools. The findings revealed that the majority of the students prefer listening to music at home and public transport. The least preferred situations for listening to music are when they are with their families and whilst reading book/newspaper/magazines. The results suggested that the most preferred genres are Rock and Blues which are closely followed by Jazz and Western Classical Music. The least preferred genres are Turkish Arabesque Music, Rap and Turkish Folk Music. It is determined that the students' music listening situation has shown significant differences according to the musical training, gender and musical genres.

In fact, driving process is a typical cyber physical process which couples tightly the cyber factor of traffic information with the physical components of the vehicles. Meanwhile, the drivers have situation awareness in driving process, which is not only ascribed to the current traffic states, but also extrapolates the changing trend. In this paper, an extended car-following model is proposed to account for drivers' situation awareness. The stability criterion of the proposed model is derived via linear stability analysis. The results show that the stable region of proposed model will be enlarged on the phase diagram compared with previous models. By employing the reductive perturbation method, the modified Korteweg de Vries (mKdV) equation is obtained. The kink-antikink soliton of mKdV equation reveals theoretically the evolution of traffic jams. Numerical simulations are conducted to verify the analytical results. Two typical traffic Scenarios are investigated. The simulation results demonstrate that drivers' situation awareness plays a key role in traffic flow oscillations and the congestion transition.

This is a qualitative research concerning on students’ creativity on problem posing task. The study aimed at describing the students’ creative thinking ability to pose the mathematics problem in structured situations with varied condition of given problems. In order to find out the students’ creative thinking ability, an analysis of mathematics problem posing test based on fluency, novelty, and flexibility and interview was applied for categorizing students’ responses on that task. The data analysis used the quality of problem posing and categorized in 4 level of creativity. The results revealed from 29 secondary students grade 8, a student in CTL (Creative Thinking Level) 1 met the fluency. A student in CTL 2 met the novelty, while a student in CTL 3 met both fluency and novelty and no one in CTL 4. These results are affected by students’ mathematical experience. The findings of this study highlight that student’s problem posing creativity are dependent on their experience in mathematics learning and from the point of view of which students start to pose problem.

Agency in Professional Self-Determination of Adolescentswith Special Social Situations of Development

Directory of Open Access Journals (Sweden)

Aron I.S.,

2017-12-01

Full Text Available The article explains the importance of agency in professional identity formation as a conscious, independent, active, responsible, professional choice relevant in modern society. Psychological readiness for agency is considered its integral indicator which includes cognitive, activity, motivational, and personality components. The paper presents outcomes of a research on the specifics of psychological readiness to professional self-determination in adolescents with special social situations of development. This research involved 211 adolescents including orphans, teenagers with deviant behavior, and gifted teenagers. A set of techniques used in the research consisted of five standard techniques and a questionnaire developed by the author. The obtained results revealed that there is a lack of readiness for professional self-determination in all adolescent groups: orphans and teenagers with deviant behaviors showed insufficient rates for all four components of readiness, while gifted adolescents showed low rates for activity and personal components. The results of this research may help develop differentiated, person-centered technologies for promoting agency in professional self-determination of adolescents with special social situations of development. The author links the prospects of further investigations with the study of positive characteristics of psychological readiness of young people with special social situations of development to professional self-determination; these characteristics can serve as a compensatory and developmental potential of agency in professional self-determination in the context of specific social contexts and limited agency-based resources of professional self-determination.

Competition in the health care market has intensified in recent years. Health care providers are increasingly adopting innovative marketing techniques to secure their positions in the marketplace. This paper examines an innovative marketing technique, situational segmentation, and assesses its applicability to the health care market. Situational segmentation has proven useful in many consumer goods markets but has received little attention in the context of health care marketing. A two-stage research process is used to develop a taxonomy of situational factors pertinent to health care choice. In stage one, focus group interviews are used to gather information which is instrumental to questionnaire development. In stage two, the responses of 151 subjects to a 51 item questionnaire are factor analyzed. The results demonstrate that situational segmentation is a viable strategy in the health care market.

Full Text Available Whilst strategies preferences develop over a person’s lifetime, due to its proximal presence the parenting context is primary significant relational context where conflict resolution skills might being learned. While disciplining and guiding the child, nurturing the child‘s psychological, physical, social, and economic well-being parent provides child with a platform to learn how to deal with conflicts (Jonyniene et al., 2015; Missotten et al., 2016. The purpose of the study was to search for the family etiology of the strategies (aggression, avoidance, submission, problem solving for coping with a social conflict situation by adolescents, the source of which is inherent in parental upbringing attitudes. D. Borecka-Biernat’s Questionnaire on studying strategies for coping with a social conflict situation by adolescents (KSMK and Parental Attitudes Scale (SPR by M. Plopa were applied in the research. The empirical research was carried out in junior high schools in Wroclaw and neighbouring towns. It comprised 493 adolescents (269 girls and 224 boys aged 13-15. In the light of the research conducted, it was found that the adolescents’ aggressive way of reacting to emotional tension resulting from a social conflict situation is shaped by inappropriate upbringing attitudes of parents towards an adolescent child. The research results within the scope of the acceptance-rejection and autonomy attitude perception reveal their lower intensification in parents of adolescents who use aggression strategy. On the other hand, it is also possible to observe a higher result concerning the inconsistent and an over demanding attitude of adolescents’ parents who use aggression as a strategy for coping with a social conflict situation. It can be assumed that due to the attitudes observed in the mother and father, the adolescents who use the strategy of avoidance, submission, and task-oriented for coping with a social conflict situation constitute a

The purpose of this study was to examine (a) the effects of three curricular activities on students'situational motivation (intrinsic motivation [IM], identified regulation [IR], external regulation, and amotivation [AM]) and physical activity (PA) levels, and (b) the predictive strength of situational motivation to PA levels. Four hundred twelve students in grades 7-9 participated in three activities (cardiovascular fitness, ultimate football, and Dance Dance Revolution [DDR]) in physical education. ActiGraph GT1M accelerometers were used to measure students' PA levels for three classes for each activity. Students also completed a Situational Motivation Scale (Guay, Vallerand, & Blanchard, 2000) at the end of each class. Multivariate analysis of variance revealed that students spent significantly higher percentages of time in moderate-to-vigorous PA (MVPA) in fitness and football classes than they did in DDR class. Students reported higher lM and IR toward fitness than DDR They also scored higher in IR toward fitness than football. In contrast, students displayed significantly lower AM toward fitness than football and DDR Hierarchical Linear Modeling revealed that IM was the only positive predictor for time in MVPA (p = .02), whereas AM was the negative predictor (p < .01). The findings are discussed in regard to the implications for educational practice.

Remember dax? Relations between children's cross-situational word learning, memory, and language abilities.

Science.gov (United States)

Vlach, Haley A; DeBrock, Catherine A

2017-04-01

Learning new words is a difficult task. Children are able to resolve the ambiguity of the task and map words to referents by tracking co-occurrence probabilities across multiple moments in time, a behavior termed cross-situational word learning (CSWL). Although we observe developments in CSWL abilities across childhood, the cognitive processes that drive individual and developmental change have yet to be identified. This research tested a developmental systems account by examining whether multiple cognitive systems co-contribute to children's CSWL. The results of two experiments revealed that multiple cognitive domains, such as memory and language abilities, are likely to drive the development of CSWL above and beyond children's age. The results also revealed that memory abilities are likely to be particularly important above and beyond other cognitive abilities. These findings have implications for theories and computational models of CSWL, which typically do not account for individual children's cognitive capacities or changes in cognitive capacities across time.

METHODOLOGICAL ELEMENTS OF SITUATIONAL ANALYSIS

2016-07-01

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.

Big losses lead to irrational decision-making in gambling situations: relationship between deliberation and impulsivity.

Directory of Open Access Journals (Sweden)

Yuji Takano

Full Text Available In gambling situations, we found a paradoxical reinforcing effect of high-risk decision-making after repeated big monetary losses. The computerized version of the Iowa Gambling Task (Bechara et al., 2000, which contained six big loss cards in deck B', was conducted on normal healthy college students. The results indicated that the total number of selections from deck A' and deck B' decreased across trials. However, there was no decrease in selections from deck B'. Detailed analysis of the card selections revealed that some people persisted in selecting from the "risky" deck B' as the number of big losses increased. This tendency was prominent in self-rated deliberative people. However, they were implicitly impulsive, as revealed by the matching familiar figure test. These results suggest that the gap between explicit deliberation and implicit impulsivity drew them into pathological gambling.

Exploring schema-driven differences in situation awareness between road users: an on-road study of driver, cyclist and motorcyclist situation awareness.

Collisions between different road users make a substantial contribution to road trauma. Although evidence suggests that different road users interpret the same road situations differently, it is not clear how road users' situation awareness differs, nor is it clear which differences might lead to conflicts. This article presents the findings from an on-road study conducted to examine driver, motorcyclist and cyclist situation awareness in different road environments. The findings suggest that, in addition to minor differences in the structure of different road users' situation awareness (i.e. amount of information and how it is integrated), the actual content of situation awareness in terms of road user schemata, the resulting interaction with the world and the information underpinning situation awareness is markedly different. Further examination indicates that the differences are likely to be compatible along arterial roads, shopping strips and at roundabouts, but that they may create conflicts between different road users at intersections. Interventions designed to support compatible situation awareness and behaviour between different road users are discussed.

Students’ analogical reasoning in novel situations: theory-like misconceptions or p-prims?

Science.gov (United States)

Fotou, Nikolaos; Abrahams, Ian

2016-07-01

Over the past 50 years there has been much research in the area of students’ misconceptions. Whilst this research has been useful in helping to inform the design of instructional approaches and curriculum development it has not provided much insight into how students reason when presented with a novel situation and, in particular, the knowledge they draw upon in an attempt to make predictions about that novel situation. This article reports on a study of Greek students, aged from 10 to 17 years old, who were asked to make predictions in novel situations and to then provide, without being told whether their predictions were correct or incorrect, explanations about their predictions. Indeed, their explanations in such novel situations have the potential to reveal how their ideas, as articulated as predictions, are formed as well as the sources they draw upon to make those predictions. We also consider in this article the extent to which student ideas can be seen either as theory-like misconceptions or, alternatively, as situated acts of construction involving the activation of fragmented pieces of knowledge referred to as phenomenological primitives (p-prims). Our findings suggest that in most cases students’ reasoning in novel situations can be better understood in terms of their use of p-prims and that teaching might be made more effective if teachers were more aware of the p-prims that students were likely to be using when presented with new situations in physics.

Objects in the world usually have names at different hierarchical levels (e.g., beagle, dog, animal). This research investigates adults' ability to use cross-situational statistics to simultaneously learn object labels at individual and category levels. The results revealed that adults were able to use co-occurrence information to learn hierarchical labels in contexts where the labels for individual objects and labels for categories were presented in completely separated blocks, in interleaved blocks, or mixed in the same trial. Temporal presentation schedules significantly affected the learning of individual object labels, but not the learning of category labels. Learners' subsequent generalization of category labels indicated sensitivity to the structure of statistical input. Copyright © 2017 Cognitive Science Society, Inc.

Miskewicz, Kelly; Fleeson, William; Arnold, Elizabeth Mayfield; Law, Mary Kate; Mneimne, Malek; Furr, R. Michael

2015-01-01

This article tested a contingency-oriented perspective to examine the dynamic relationships between in-the-moment borderline personality disorder (BPD) symptom events and in-the-moment triggers. An experience sampling study with 282 adults, including 77 participants with BPD, obtained reports of situational triggers and BPD symptom events five times daily for two weeks. Triggers included being rejected, betrayed, abandoned, offended, disappointed, having one’s self-concept threatened, being in a boring situation, and being alone. BPD was associated with increased situational triggers. Multilevel models revealed significant within-person associations between situational triggers and BPD symptoms for the average participant in the study, with significant individual variance in the strength and direction of trigger-symptom contingencies. Most trigger-symptom contingencies were stronger for individuals with higher borderline symptomatology, suggesting that triggers are meaningfully related to BPD. These findings highlight possible proximal mechanisms that maintain BPD and help explain the course of a disorder often described as chaotic and unpredictable. PMID:26200848

Learning Situations in Nursing Education: A Concept Analysis.

2018-02-01

The nursing student requires opportunities to learn within authentic contexts so as to enable safe and competent practice. One strategy to facilitate such learning is the creation of learning situations. A lack of studies on the learning situation in nursing and other health care fields has resulted in insufficient knowledge of the characteristics of the learning situation, its antecedents, and consequences. Nurse educators need to have comprehensive and practical knowledge of the definition and characteristics of the learning situation so as to enable their students to achieve enhanced learning outcomes. The aim of this study was to clarify the concept of the learning situation as it relates to the education of nurses and improve understanding of its characteristics, antecedents, and consequences. The Bonis method of concept analysis, as derived from the Rodgers' evolutionary method, provided the framework for analysis. Data collection and analysis were undertaken in two phases: "interdisciplinary" and "intra-disciplinary." The data source was a search of the literature, encompassing nursing and allied health care professions, published from 1975 to 2016. No agreement on the conceptual phenomenon was discovered in the international literature. The concept of a learning situation was used generally in two ways and thus classified into the themes of: "formal/informal learning situation" and "biologic/nonbiologic learning situation." Antecedents to the creation of a learning situation included personal and environmental factors. The characteristics of a learning situation were described in terms of being complex, dynamic, and offering potential and effective learning opportunities. Consequences of the learning situation included enhancement of the students' learning, professionalization, and socialization into the professional role. The nurse educator, when considering the application of the concept of a learning situation in their educational planning, must

Narrative Construction, Social Perceptions, and the Situation Model.

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. © 2016 by the Society for Personality and Social Psychology, Inc.

Diagnostic orientation in control of disturbance situations

International Nuclear Information System (INIS)

Hukki, K.; Norros, L.

1993-01-01

The object of the study is diagnostic judgement in the control of dynamic processes. The starting point was the known difficulty process operators have in utilizing knowledge of process dynamics in disturbance situations that require both diagnostic and prognostic actions. A model of the diagnostic judgement process as a construction of coherent interpretation of the situation is outlined, and comprehensive data from simulated disturbance handling by 6 crews of a PWR type nuclear power plant was analysed. The phase of analysis included evaluation of the adequacy of task performance, utilization of available process information, and evaluation of the interpretation of disturbance situations. The results suggest that a functional orientation towards task performance allows a more coherent and comprehensive interpretation of the situation and more adequate task performance. Coherence of interpretation seems to be reflected in a higher subjective certainty compared with crews with an incoherent interpretation. (author). 15 refs, 2 figs, 2 tabs

This report presents methods for continuous measures for Situation Awareness and Workload. The objective has been to identify, develop and test the new measures, and compare them to instruments that require interruptions of scenarios. The new measures are: (1) the Visual Indicator of Situation Awareness (VISA); where Situation Awareness is scored from predefined areas of visual interest critical for solving scenarios. Visual monitoring of areas was recorded by eye-movement tracking. (2) Workload scores reflected by Extended Dwell Time (EDT) and the operator Activity Level. EDT was calculated from eye-movement data files, and the activity level was estimated from simulator logs. Using experimental data from the 1996 CASH NRC Alarm study and the 1997 Human Error Analysis Project/ Human-Centred Automation study, the new measurement techniques have been tested and evaluated on a preliminary basis. The results showed promising relationships between the new continuous measures of situation awareness and workload, and established instruments based upon scenario interruptions. (author)

Management of agricultural aspects in nuclear and/or radiological emergency situations

1997-01-01

In revealing the agricultural aspects of the nuclear and/or radiological emergency situations the paper stresses upon the shocking role which the Chernobyl nuclear accident had on the agricultural management in France. Merely, the misunderstand, unawareness and lack of information relative to production as well as contamination conditions led to damages of FF 150 millions to the detriment of French farmers. Reflexions upon and analysis of this case has led to several conclusions concerning the role of information, the situation of international standards, and the lack of knowledge in important practical issues related to radioisotope migration in plants and agricultural products. Among the future lines of action in this field there are discussed the issues of indemnity, post-accident planning, drilling and information. In conclusion the following points are highlighted: 1. Redefinition of the EU standards; 2. Updating the situation of food and agricultural production units located around basic nuclear facilities in order to dispose of the necessary statistics to make decisions in emergency situations; 3. In absence of a post-accident plan, a scheme of action should be elaborated able to be rapidly implemented by public authorities in order to protect the consumer and restrict the supply to local market and exportation only to warranted agricultural products

Situation testing: the case of health care refusal.

Science.gov (United States)

Després, C; Couralet, P-E

2011-04-01

Situation testing to assess physicians' refusal to provide healthcare is increasingly used in research studies. This paper aims to explain the relevance and limits of this method. Conducted in 2008-2009, this study was designed to assess the rate of healthcare refusal among several categories of private practitioners toward patients covered by the French public means-tested complementary health insurance (CMUc) when they requested a first appointment by phone. The other objectives were to study the determinants of healthcare refusal and assess the method. The study was conducted on a representative sample of Paris-based dentists and physicians in five categories: general practitioners, medical gynecologists, ophthalmologists, radiologists, and dentists. The method was based on two protocols. In the first scenario, an actor pretended to be a CMUc beneficiary and, in the second one, he did not give information about his health coverage but hinted at a low socioeconomic status. The two protocols were compared and procedures checking the relation between refusal and CMUc coverage were implemented in each of them. In the scenario in which the patient declared being a CMUc beneficiary, the results showed different refusal rates depending on the type of practitioner, physician, or dentist, their specialty, and whether or not, they charge more than the standard set fee. In the second scenario, refusal rates were much lower. The comparison of the two protocols seems to confirm the existence of discrimination based on CMUc affiliation rather than patients' socioeconomic status. The discussion presents the limits of situation testing, which remains an experimental instrument because it does not observe reality but reveals behaviors in situation. The findings cannot be extrapolated and are limited in time. The statistical analysis is only valid if the procedure followed is precise and applied consistently using a preset scenario. In addition, the discriminatory nature of the

A development of a quantitative situation awareness measurement tool: Computational Representation of Situation Awareness with Graphical Expressions (CoRSAGE)

International Nuclear Information System (INIS)

Yim, Ho Bin; Lee, Seung Min; Seong, Poong Hyun

2014-01-01

Highlights: • We proposed quantitative situation awareness (SA) evaluation technique. • We developed a computer based SA evaluation tool for NPPs training environment. • We introduced three rules and components to express more human-like results. • We conducted three sets of training with real plant operators. • Results showed that the tool could reasonably represent operator’s SA. - Abstract: Operator performance measures are used for multiple purposes, such as control room design, human system interface (HSI) evaluation, training, and so on. Performance measures are often focused on results; however, especially for a training purpose – at least in a nuclear industry, more detailed descriptions about processes are required. Situation awareness (SA) measurements have directly/indirectly played as a complimentary measure and provided descriptive insights on how to improve performance of operators for the next training. Unfortunately, most of the well-developed SA measurement techniques, such as Situation Awareness Global Assessment Technique (SAGAT) need an expert opinion which sometimes troubles easy spread of measurement’s application or usage. A quantitative SA measurement tool named Computational Representation of Situation Awareness with Graphical Expressions (CoRSAGE) is introduced to resolve some of these concerns. CoRSAGE is based on production rules to represent a human operator’s cognitive process of problem solving, and Bayesian inference to quantify it. Petri Net concept is also used for graphical expressions of SA flow. Three components – inference transition, volatile/non-volatile memory tokens – were newly developed to achieve required functions. Training data of a Loss of Coolant Accident (LOCA) scenario for an emergency condition and an earthquake scenario for an abnormal condition by real plant operators were used to validate the tool. The validation result showed that CoRSAGE performed a reasonable match to other performance

Full Text Available The article considers the problem of computer-aided instruction in context-chain motivated situation control system of the complex technical system behavior. The conceptual and formal models of situation control with practical instruction are considered. Acquisition of new behavior knowledge is presented as structural changes in system memory in the form of situational agent set. Model and method of computer-aided instruction represent formalization, based on the nondistinct theories by physiologists and cognitive psychologists.The formal instruction model describes situation and reaction formation and dependence on different parameters, effecting education, such as the reinforcement value, time between the stimulus, action and the reinforcement. The change of the contextual link between situational elements when using is formalized.The examples and results of computer instruction experiments of the robot device “LEGO MINDSTORMS NXT”, equipped with ultrasonic distance, touch, light sensors.

Prior research has shown that various situational factors and behaviors can affect one's perception of whether a rape has occurred. Moreover, some hold false beliefs about rape. This can also affect one's perception of ambiguous situations. This study included the administration of a survey to 584 college students; the survey examined the prevalence of rape myths and responses to vignettes of potential rape scenarios. It was found that although the majority of this sample did not support rape myths, male students were significantly more likely than female students to support rape myths. Furthermore, approximately 20% of students did support one subscale of the rape myth scale: He didn't mean to [commit rape]. The results also revealed an interaction effect between the observer's sex and the victim's sex, suggesting a complex gender relationship.

Person-situation interactions have attracted researchers' attention for decades. Likewise, the current work focuses on the interaction of honesty-humility and situational conditions in bringing about counterproductive work behaviour (CWB). As such, we introduce perceptions of organizational...... politics as a situational construct representing an opportunity for CWB. In a sample of N = 148 employees we found that particularly individuals low in honesty-humility were affected by situational circumstances. By contrast, those high in honesty-humility reported practically the same (lower) amount...... of CWB independent of the level of perceptions of organizational politics. In other words, employees low in honesty-humility were especially likely to condition their behaviour on environmental factors, a result that mirrors previous findings....

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.

The main aim of this research was to investigate the decision making process in risky situations. We studied how different types of feedback on risky driving behaviors modulate risk evaluation and risk-taking. For a set of risky traffic situations, participants had to make evaluative judgments (judge the situation as risky or not) and urgent decisions (brake or not). In Experiment 1, participants received feedback with and without negative emotional content when they made risky behaviors. In Experiment 2 we investigated the independent effects of feedback and negative emotional stimuli. The results showed three important findings: First, urgent decisions were faster [F(1, 92) = 6.76, p = .01] and more cautious [F(1, 92) = 17.16, p towards more cautious responses [F(1, 111) = 14.09, p emotional stimuli had an effect only when they were presented as feedback. The results of this research increase our understanding of the processes involved in risky driving behavior and suggest efficient ways to control risk taking through the use of feedback.

Highlights: ► An EID prototype for monitoring primary side of nuclear power plant is proposed. ► The effectiveness of the prototype is validated using a partial scoped dynamic mockup in terms of situation awareness. ► The validation is based on comparison of a mimic display with an EID plus mimics. - Abstract: The purpose of this study is to validate whether an ecological interface design (EID) improves operators’ situation awareness in an advanced control room of a nuclear power plant (NPP). EID is defined as an approach to interface design that was introduced specifically for complex socio-technical, real-time, and dynamic systems. The EID technology has not yet been adapted to the nuclear power industry due to lack of empirical studies. Especially in a situational awareness aspect, many researchers have predicted that the EID will support operators to detect unanticipated events. Just a few studies, however, unveiled the positive effect of the EID display on human performance using a full scoped simulator. In this study, to investigate whether an EID improves operators’ situational awareness, we developed an EID prototype for nuclear power operations and a partial scoped dynamic mockup to validate the effectiveness of the EID prototype. Three experienced operators were involved as subjects in our study and they were fully well trained for using the EID prototype. We compared two types of situations in terms of situation awareness. One is mimic based information display and the other is a mimic plus EID based information display. The result of our study revealed that a mimic plus EID based information display is more effective than a mimic based information display in terms of situation awareness. This study is significant in that the EID as an emerging technology is adoptable to a digitalized control room in an aspect of improving operators’ situation awareness.

Situational theory of leadership.

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.

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.

1991-01-01

Situation awareness, a current mental mode of the environment, is critical to the ability of operators to perform complex and dynamic tasks. This should be particularly true for teleoperators, who are separated from the situation they need to be aware of. The design of the man-machine interface must be guided by the goal of maintaining and enhancing situation awareness. The objective of this work has been to build a foundation upon which research in the area can proceed. A model of dynamic human decision making which is inclusive of situation awareness will be presented, along with a definition of situation awareness. A method for measuring situation awareness will also be presented as a tool for evaluating design concepts. The Situation Awareness Global Assessment Technique (SAGAT) is an objective measure of situation awareness originally developed for the fighter cockpit environment. The results of SAGAT validation efforts will be presented. Implications of this research for teleoperators and other operators of dynamic systems will be discussed.

Full Text Available Purpose . Determination which areas of teacher’s work are primary sources of stress, denomination of the extent to which disciplinary problems with students were stress inducing, and what was the frequency and intensity of these situations. Material and methods. The study involved 180 teachers from junior high schools, among which two groups were selected: physical education teachers (74 persons and teachers of other subjects (106 persons. The reason for this division was the necessity of identifying the groups of teachers differing in specifics of school subjects, studies which they graduated from, and determine the typical areas of difficulty experienced. The research was based on a diagnostic survey and a questionnaire. Results . Teaching profession is considered as psychologically challenging occupation due to numerous occurrences of stressful situations. Yet it is not equally aggravating for everyone – there are well-functioning teachers who cope easily, but on the other hand, there are cases of serious psychosomatic consequences caused by frequent and prolonged pressures. Abilities of dealing with difficult situations largely depend upon one’s individual predispositions, resistance to stress, way of assessing a situation and resulting type of action. Conclusions . The ability (or lack of it of coping with range of educational activities may determine the intensity of experienced difficulties, and therefore the frequency of occurring stressful situations. Lack of skills in the area of interpersonal relations translates to inability to coping with problematic situations with pupils. This leads the teacher to awareness of own inefficiency and helplessness, which increases the intensity of experienced stress.

We assessed the urinary indexes of hydration status of Greco-Roman wrestlers in an authentic precompetition situation at the time of official weigh-in (OWI). A total of 51 of 89 wrestlers competing in the Estonian Championship in 2009 donated a urine sample. Questionnaire responses revealed that 27 wrestlers (body mass losers (BMLs)) reduced body mass before the competition, whereas 24 wrestlers (those who do not lose body mass (n-BMLs)) did not. In 42 wrestlers, values of urine specific gravity ≥1.020 and urine osmolality ≥700 mOsmol·kg(-1) revealed a hypohydrated status. The prevalence of hypohydration in the BMLs (96%) was higher than in the n-BMLs (67%) (χ(2) = 7.68; p 1.030) was 5.3 times greater (χ(2) = 8.32; p OWI. The prevalence of hypohydration and serious hypohydration is especially high among wrestlers who are accustomed to reducing body mass before competition. These results suggest that an effective rehydration strategy is needed for Olympic-style wrestlers, and that changes in wrestling rules should be considered to reduce the prevalence of harmful body mass management behaviours.

Lee, Hyun Chul; Seong, Poong Hyun

2009-01-01

Situation assessment is the process of developing situation awareness and situation awareness is defined as 'the perception of the elements in the environment within a volume of time and space, the comprehension of their meaning and the projection of their status in the near future.' Situation awareness is an important element influencing human actions because human decision making is based on the result of situation assessment or situation awareness. There are many models for situation awareness and those models can be categorized into qualitative or quantitative. As the effects of some input factors on situation awareness can be investigated through the quantitative models, the quantitative models are more useful for the design of operator interfaces, automation strategies, training program, and so on, than the qualitative models. This study presents the review of two quantitative models of situation assessment (SA) for nuclear power plant operators

Representing Operational Modes for Situation Awareness

Kirchhübel, Denis; Lind, Morten; Ravn, Ole

2017-01-01

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

Full Text Available This study focuses on learning about fish biodiversity via mobile devices in a situated learning scenario. Mobile devices do not only facilitate relating the presented information to the real world in a direct way; they also allow the provision of dynamic representations on demand. This study asks whether mobile devices are suited to support knowledge acquisition in a situated learning scenario and whether providing dynamic content is an additional benefit of mobile devices in combination with a real-world experience. The study was conducted during a regular university course at the Mediterranean Sea. Students had to acquire knowledge on 18 Mediterranean fish species by using either static (n = 16 or dynamic learning materials (n = 17. An initial classroom activity was followed by a real-world experience with mobile devices (snorkelling activity. Learning outcomes were measured before and after snorkelling. A 2×2 mixed ANOVA revealed that students performed better after than before the mobile learning experience, whereas no main effect for learning material could be found. However, an interaction between both factors indicated that the knowledge gain in the dynamic group exceeded the knowledge gain in the static group. These results indicate that mobile devices are helpful to unfold the potential of dynamic visualisations for learning biodiversity in a situated learning scenario.

Managing and engineering in complex situations

CERN Document Server

Sousa-Poza, Andres

2013-01-01

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 ...

Implications of the new ICRP recommendations for the management of post-accidental situations

1992-01-01

From an analysis of the new ICRP recommendations in relation with the management of post-accidental situations, there appears that no significant changes in comparison with the present situation will result. The consequences are rather an attempt to further clarify and justify the way in which the system of radiation protection applies to such situations, corresponding clearly to 'intervention situation', especially: - the use of the justification and optimization principles for the decision of implementing a protective measure. - the use of 'intervention levels' instead of individual 'dose limits'. In addition, and although there is no link at all between the dose limits applying in 'practices situations' and the intervention levels, the increase of risk factors could also result in a change of intervention levels.

Guangheng Dong

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.

Social patterns revealed through random matrix theory

Sarkar, Camellia; Jalan, Sarika

2014-11-01

Despite the tremendous advancements in the field of network theory, very few studies have taken weights in the interactions into consideration that emerge naturally in all real-world systems. Using random matrix analysis of a weighted social network, we demonstrate the profound impact of weights in interactions on emerging structural properties. The analysis reveals that randomness existing in particular time frame affects the decisions of individuals rendering them more freedom of choice in situations of financial security. While the structural organization of networks remains the same throughout all datasets, random matrix theory provides insight into the interaction pattern of individuals of the society in situations of crisis. It has also been contemplated that individual accountability in terms of weighted interactions remains as a key to success unless segregation of tasks comes into play.

Impressions of Milgram's obedient teachers: situational cues inform inferences about motives and traits.

Reeder, Glenn D; Monroe, Andrew E; Pryor, John B

2008-07-01

The research investigated impressions formed of a "teacher" who obeyed an experimenter by delivering painful electric shocks to an innocent person (S. Milgram, 1963, 1974). Three findings emerged across different methodologies and different levels of experimenter-induced coercion. First, contrary to conventional wisdom, perceivers both recognized and appreciated situational forces, such as the experimenter's orders that prompted the aggression. Second, perceivers' explanations of the teacher's behavior focused on the motive of obedience (i.e., wanting to appease the experimenter) rather than on hurtful (or evil) motivation. Despite this overall pattern, perceptions of hurtful versus helpful motivation varied as a function of information regarding the level of coercion applied by the experimenter. Finally, theoretically important relationships were revealed among perceptions of situations, motives, and traits. In particular, situational cues (such as aspects of the experimenter's behavior) signaled the nature of the teacher's motives, which in turn informed inferences of the teacher's traits. Overall, the findings pose problems for the lay dispositionism perspective but fit well with multiple inference models of dispositional inference.

As advised by the procedure workshop convened in Halden in 2000, the Halden Project conducted an experiment on the effect of automation of Computerised Procedure Systems (CPS) on situation awareness and human performance. The expected outcome of the study was to provide input for guidance on CPS design, and to support the Halden Project's ongoing research on human reliability analysis. The experiment was performed in HAMMLAB using the HAMBO BWR simulator and the COPMA-III CPS. Eight crews of operators from Forsmark 3 and Oskarshamn 3 participated. Three research questions were investigated: 1) Does procedure automation create Out-Of-The-Loop (OOTL) performance problems? 2) Does procedure automation affect situation awareness? 3) Does procedure automation affect crew performance? The independent variable, 'procedure configuration', had four levels: paper procedures, manual CPS, automation with breaks, and full automation. The results showed that the operators experienced OOTL problems in full automation, but that situation awareness and crew performance (response time) were not affected. One possible explanation for this is that the operators monitored the automated procedure execution conscientiously, something which may have prevented the OOTL problems from having negative effects on situation awareness and crew performance. In a debriefing session, the operators clearly expressed their dislike for the full automation condition, but that automation with breaks could be suitable for some tasks. The main reason why the operators did not like the full automation was that they did not feel being in control. A qualitative analysis addressing factors contributing to response time delays revealed that OOTL problems did not seem to cause delays, but that some delays could be explained by the operators having problems with the freeze function of the CPS. Also other factors such as teamwork and operator tendencies were of importance. Several design implications were drawn

Full Text Available The article deals with analysis of psychological factors and characteristics of victim behavior of women in situations of domestic violence. We considered prerequisites for the formation of victim behavior in women, motives and psychological implication of protective mechanisms of women in a dysfunctional family. It is noted that the victimized women are inclined to sacrifice their "I" in order to be accepted by family system and this characteristic belongs to the general features of victimization, which manifests itself in disadaptive behavior of subjects. We revealed and described the psychological characteristics of victim behavior of women in situations of domestic violence, including neuroticism, affective functions disorder, state of learned helplessness, cognitive disorders, deformed self-perception and low self-esteem, proneness to conflict and contradictions, post-traumatic stress disorder, boundary violations of “Ego”, traumatic childhood experiences and behaviors of parents.

Planning as situated design

Tanaka, Yuko; Kusumi, Takashi

2016-04-01

The present study examined when people decide to choose an expression that is based on critical thinking, and how situational and individual variables affect such a decision process. Given a conversation scenario including overgeneralization with two friends, participants decided whether to follow the conversation by a critical-thinking expression or not. The authors controlled purpose and topic as situational variables, and measured critical-thinking ability, critical-thinking disposition, and self-monitoring as individual variables. We conducted an experiment in which the situational variables were counterbalanced in a within-subject design with 60 university students. The results of logistic regression analysis showed differences within individuals in the decision process whether to choose a critical-thinking expression, and that some situational factors and some subscales of the individual measurements were related to the differences.

Dong, G; Lin, X; Zhou, H; Lu, Q

2014-07-11

Humans have been consistently shown to be bad at making decisions, especially in disadvantageous situations. In this study, we designed a task that simulates real-life non-strategic gambling to examine the effect of win-lose balance situations (WIN, LOSS, TIE) on decision-making. In behavioral performances, participants showed shorter response time (RT) in LOSS than in WIN and TIE conditions. Imaging results revealed that decisions in WIN are associated with increased brain activations in the posterior cingulate cortex; decisions in LOSS are associated with increased brain activations in the insula and decreased activations in the inferior frontal gyrus (IFG). Positive correlation was found between brain activation in IFG and RT in LOSS. Overall, we concluded that, in disadvantageous conditions, participants are frustrated by their negative results and tend to make a random selection without full consideration. In advantageous conditions, participants' motivations to gamble are elicited and they tend to engage in more endeavors in making decisions. Copyright © 2014 IBRO. Published by Elsevier Ltd.

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.

Streptococcus suis, a major porcine pathogen and an important zoonotic agent, is considered to be composed of phenotypically and genetically diverse strains. However, recent studies reported several "S. suis-like strains" that were identified as S. suis by commonly used methods for the identification of this bacterium, but were regarded as distinct species from S. suis according to the standards of several taxonomic analyses. Furthermore, it has been suggested that some S. suis-like strains can be assigned to several novel species. In this review, we discuss the current taxonomical situation of S. suis with a focus on (1) the classification history of the taxon of S. suis; (2) S. suis-like strains revealed by taxonomic analyses; (3) methods for detecting and identifying this species, including a novel method that can distinguish S. suis isolates from S. suis-like strains; and (4) current topics on the reclassification of S. suis-like strains.

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

Me or you? Neural correlates of moral reasoning in everyday conflict situations in adolescents and adults.

Throughout adolescence, progress in the understanding of the moral domain as well as changes in moral behavior is observable. We tested 16 adolescents (14-16 years of age) and 16 healthy adults (22-31 years of age) on the developmental changes in everyday moral decision making using functional magnetic resonance imaging (fMRI). Using verbal stories describing everyday moral conflict situations, subjects had to decide between a moral standard or a personal desire. In the moral conflict situations, adolescents not only chose significantly more often the hedonistic alternative than adults, but they also reported higher certainty ratings. Contrasted with everyday social conflict situations that required a decision between a social-oriented behavior and a personal need, moral conflict situations induced an activity increase in frontal areas, the middle temporal gyrus, the thalamus, and the parahippocampal gyrus in adolescents compared to adults. Moreover, a closer look at the moral conflict situations revealed that adolescents showed more activity than adults in brain areas that are also centrally involved in theory of mind (ToM) during morally oriented decisions in contrast to personal-oriented decisions. This indicated that the development of moral reasoning may be strongly correlated with the development of ToM reasoning.

Several studies have been reported on soil to grass equilibrium transfer factors and grass to cow's milk transfer coefficients for 137 Cs for the environs of different nuclear power plants of both India and other parts of the world. In such studies, the activity concentration of 137 Cs is measured in grass collected from different places. Cow's milk samples are collected from nearby localities or from milk dairies and analyzed for 137 Cs and the grass to cow's milk transfer coefficient is estimated. In situation where 137 Cs is not present in measurable activity concentrations, its stable counterpart (Cs) is measured for the estimation of transfer coefficients. These transfer coefficient values are generally used in theoretical models to estimate the dose to the population for hypothetical situation of emergency. It should be noted that the transfer coefficients obtained for equilibrium conditions may not be totally applicable for emergency situation. However, studies aimed at evaluating transfer coefficients for emergency situations are sparse because nuclear power plants do not release 137 Cs during normal operating situations and therefore simulating situation of emergency release is not possible. Hence, the only method to estimate the grass to milk transfer coefficient for emergency situation is to spike the grass with small quantity of stable Cs. This paper reports the results of grass to milk transfer coefficients for stable isotope of Cesium (Cs) for emergency situation

Full Text Available Abstract Objective Anxiety as a uni- or multidimensional construct has been under discussion. The unidimensional approach assumes that there is a general trait anxiety, which predisposes the individuals to increases in state anxiety in various threatening situations. In this case, there should be a correlation between state and trait anxiety in any situation of threat. Therefore, the aim of this study was to investigate the correlation between trait and state anxiety in participants exposed to two different anxiogenic situations: interpersonal threat (Video-Monitored Stroop Test – VMST and physical threat (third molar extraction – TME. Methods Participants with various levels of trait anxiety (general trait: State-Trait Anxiety Inventory – STAI, Hospital Anxiety and Depression Scale; specific trait: Social Phobia Inventory, Dental Anxiety Scale had their anxious state evaluated (STAI, self-evaluation of tension level, heart rate, electromyogram activity before, during and after the VMST or the TME. Results In VMST, trait anxiety correlated to state anxiety (psychological parameters in all test phases. However, in TME, the only trait measurement that correlated to state anxiety (psychological parameters was the Dental Anxiety Scale. Conclusion Trait anxiety correlates positively to state anxiety in situations of interpersonal threat, but not of physical threat.

Full Text Available The personalization of learning is a major pedagogical challenge solicited by pedagogues and didacts. There are several projects about the production of personalizable learning situations such as Reload-LDE and Alfanet. These projects are interested in producing new standardized and personalizable learning situations. However, on the Web, an important number of learning situations exist. These situations are rich in information but don't consider all the characteristics of participants taking part in the learning, nor their technical environments. In this paper we suggest a help system that can transform an existing learning situation to another structure standardized and personalizable depending on the context of learning personalization that we have defined.

2013-08-01

Full Text Available In this research, we aimed to understand the loss and grief process and the occupational therapy assistance to a hospitalized child undergoing a scalping situation. It is a case study of qualitative approach. This survey was carried out with the participation of an 8-year-old female scalping victim. Results revealed that the scalping caused many changes such as loss of hair and parts of the facial skin. The child was hospitalized, staying away from occupational activities such as studying, playing, among others. We observed the expression of feelings such as fear, shame, anxiety and sadness generated by hair loss. Thus, we believe that this research is of high relevance because it allowed contact with a theme so characteristic of northern Brazil, as well as with the perception and clarification about the importance of occupational therapy assistance in providing space for expression and reframing of the doings, giving the opportunity to this child to resume her significant occupational activities.

Update on the nutrition situation.

Science.gov (United States)

Mason, J; Garcia, M

1995-01-01

The Update on the Nutrition Situation, 1994 was published in early 1995 by the United Nations Subcommittee on Nutrition. Thus, data available at the country level about estimates of the nutritional situation now provide trends of prevalences of underweight children in 35 countries for the 1990s. In Sub-Saharan Africa recent deterioration has occurred as a result of the general worsening of nutrition in Africa. However, in the Near East, North Africa, and South America the generally improving trends of the 1980s seem to be continuing with the likelihood of reaching the prevalences of the developed countries by the year 2000. A surveillance system in Bangladesh indicates improvement from 1990 to 1993; however, India data for 1991/92 indicate deterioration in 3 states and no significant change in 4, possibly connected the economic slowdown in the early 1990s. In many countries of southeast Asia, China, Middle America and the Caribbean, South America, the Near East and North Africa the improvement of rates could result in halving the prevalences of underweight children. The gross domestic product (GDP) is an important indicator of nutritional performance. During 1985-92 in Sub-Saharan Africa GDP declined by 0.8% and consequently the nutritional situation also deteriorated. In other areas of the world the GDP growth rates improved after 1990 and the underweight trends in the early 1990s were generally similar to those of the late 1980s. The nutritional improvement outside Sub-Saharan Africa and possibly India continued in the early 1990s. Rapid economic growth was associated with improving nutrition in Thailand and Vietnam in the 1980s and also to a smaller extent for Indonesia and China. Faster than average improvement is plausible for Jamaica, Sri Lanka, and Zimbabwe. Deteriorating cases are Ethiopia, Madagascar, and Rwanda. Economic growth, health, education, and community-based nutrition programs all contribute to improving nutrition.

The Rationale of Crisis Management – On the Handling of Coincidence in Economic Situation

Peter Bendixen

2010-07-01

Full Text Available The subject of this essay is too complex a problem as to cover all details in depth and, thus, draws its attention only to core aspects of the handling of coincidence leaving out sophisticated studies and analytic findings as well as detailed reference to economic literature though there is not very much. On the other hand, for a lot of actual as well as general reasons, the subject is too important a matter as to ignore the serious methodological problems of crisis management, which are rooted in some politically still active bias hidden in orthodox neo-classical economics (Stiglitz 2010. If crisis management continues to follow traditional rationales, it will fail realizing the increasing dynamic of crises within the globalising economies of the world. No existing economy can be considered as an isolated system of its own embedded in a stable composition of societal surroundings. Obviously, many a critical situation has its origin in the sphere of civilization, of political discrepancies, and of administrative inflexibilities. On the other hand, any grave amplitude of markets would touch the entire social surrounding. The belief in the markets’ strength of self-regulation is a dangerous construction of orthodox economics (Bendixen 2009b, 2010. The view on crises suggested here is that of a holistic approach to understand a critical situation. Any interpretation of a situation includes empirical dates and figures based on analytic research, but solving a problem is not an act of logical derivation from findings, as if a solution can be excavated in the mud of reality by empirical studies only. Empirical figures report events of the past; the future does not reveal any empiricism. This would be a contradiction in itself. The end of a crisis as well as the search for solutions to fight the problems revealed is unavoidably a view into the future. Therefore, the rationale of crisis management cannot be made of pure empiricism but should include a

Role of the ventrolateral orbital cortex and medial prefrontal cortex in incentive downshift situations.

Science.gov (United States)

Ortega, Leonardo A; Glueck, Amanda C; Uhelski, Megan; Fuchs, Perry N; Papini, Mauricio R

2013-05-01

The present research evaluated the role of two prefrontal cortex areas, the ventrolateral orbital cortex (VLO) and the medial prefrontal cortex (mPFC), on two situations involving incentive downshifts, consummatory successive negative contrast (cSNC) with sucrose solutions and Pavlovian autoshaping following continuous vs. partial reinforcement with food pellets. Animals received electrolytic lesions and then were tested on cSNC, autoshaping, open-field activity, and sucrose sensitivity. Lesions of the VLO reduced suppression of consummatory behavior after the incentive downshift, but only during the first downshift trial, and also eliminated the enhancement of anticipatory behavior during partial reinforcement, relative to continuous reinforcement, in autoshaping. There was no evidence of specific effects of mPFC lesions on incentive downshifts. Open-field activity was also reduced by VLO lesions, but only in the central area, whereas mPFC lesions had no observable effects on activity. Animals with mPFC lesions exhibited decreased consumption of the lowest sucrose concentration, whereas no effects were observed in animals with VLO lesions. These results suggest that the VLO may exert nonassociative (i.e., motivational, emotional) influences on behavior in situations involving incentive downshifts. No clear role on incentive downshift was revealed by mPFC lesions. Copyright © 2013 Elsevier B.V. All rights reserved.

Kanao, Keisuke

1981-01-01

About the situation of nuclear medicine technologists in Japan, survey was made in August, 1979, by sending questionnaire to 219 facilities, and 341 technologists responded, the recovery rate being 70%. About the situation in the United States, the data were taken from the similar survey results in 1975 and 1976. The results in Japan, as compared with those in the United States, are described as follows: years of experience, contents of work, participation in society meetings and others, and occupation prior to the employment as nuclear medicine technologists. The findings are interesting in such items as the sexes of the technologists, the participation in meetings, and the types of works. In Japan, the technologists are dominantly male, while in the United States, more than 80% are female. In Japan, 97% of the technologists participated in society meetings and others. (J.P.N.)

The Situation Analysis Study of the family planning program in Kenya.

Science.gov (United States)

Miller, R A; Ndhlovu, L; Gachara, M M; Fisher, A A

1991-01-01

A new, relatively "quick and clean" operations research approach called a "situation analysis" was developed for examining the strengths and weaknesses of the family planning program of Kenya. Field research teams visited a stratified random sample of 99 of the Ministry of Health's approximately 775 service delivery points. Observation techniques and interviewing were used to collect information on program components and on the quality of care provided to new family planning clients during the observation day. As late as 1986, the Kenya program was rated "weak" and "poor" in the international literature. The Kenya Situation Analysis Study found a functioning, integrated maternal and child health/family planning program serving large numbers of clients, with an emphasis on oral contraceptives and Depo-Provera (and an underemphasis on permanent methods). Although a number of program problems were revealed by the study, overall, in terms of performance, a rating of "moderate" is suggested as more appropriate for Kenya's national family planning program today. In terms of the quality of care, a "moderate to moderate-high" rating is suggested.

Latifah, T.; Cahya, E.; Suhendra

2017-09-01

Nowadays, the usage of quantities can be seen almost everywhere. There has been an increase of quantitative thinking, such as quantitative reasoning and quantitative literacy, within the context of daily life. However, many people today are still not fully equipped with the knowledge of quantitative thinking. There are still a lot of individuals not having enough quantitative skills to perform well within today’s society. Based on this issue, the research aims to improve students’ quantitative literacy in junior high school. The qualitative analysis of written student work and video observations during the experiment reveal that the impact of situation-based learning affects students’ quantitative literacy.

The independent effects of personality and situations on real-time expressions of behavior and emotion.

Science.gov (United States)

Sherman, Ryne A; Rauthmann, John F; Brown, Nicolas A; Serfass, David G; Jones, Ashley Bell

2015-11-01

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. (c) 2015 APA, all rights reserved).

Fukushima 2014: situation and perspectives in 10 questions

Barre, Bertrand; Perves, Jean-Pierre; Xerri, Christophe; Clement, Thibault; Le Ngoc, Boris; Sorin, Francis

2014-01-01

Illustrated by maps, data graphs and tables, this article proposes answers to ten questions related to the situation and to the perspectives of evolution for the Fukushima power plant and its region. Is there any progress in the accident analysis and understanding? What about safety arrangements implemented in France in the light of lessons learned from the accident? What about the situation on the plant site? Is the site still releasing radioactivity towards the outside, the region and the ocean (atmospheric releases, contaminated liquid releases, sea water contamination, storage and processing of huge quantities of water)? What about working conditions and the situation of personnel working on the site? How is the dismantling of equipment prepared and started? What about decontamination works in the territories, i.e. evacuation zone and beyond (existence of different decontamination areas, performed and started decontamination works, residue storage site, and implemented decontamination methods)? What about the coming back of populations to their evacuated dwellings (on a short, medium or long term)? What are the last results of studies of the health impact of the accident in the present period and on a longer term? What about the energy situation in Japan and will the electronuclear program be launched again on a large scale (possible restart of some reactors in 2014, dramatic consequences for the Japanese economy)?

Sánchez-Suárez, Diana M; Giraldo-Puerta, Alexandra; Giraldo-Pineda, Álvaro; Forero-Pulido, Constanza

2016-06-01

Objective To understand the meanings, through the description of experiences that street merchants have of their interactions with children in a street situation in downtown of Medellin in 2013. Methodology Qualitative investigation with ethnographic approach. Observations were made in the zone at different times of the day. Twelve interviews with street merchants were held in their work places. Records were kept in a field journal. Results The street merchants and children in street situations share the same space. Both groups try to survive and their relationship is mediated by the trust-distrust that is established between them. The coexistence generates ambivalent feelings. For the street merchants, children in street situations are the result of abandonment by the family, the state and society. They live in a hard world in which they are exposed to a series of risks that they must face. Conclusion The interaction between street merchants and children in street situations is good to the extent that conflicts are avoided, establishing norms of coexistence. The element that determines this relationship is trust-distrust. In trust, strong affective ties are generated, considering each other family. Distrust generates a preventative attitude.

As the development of Web 2.0, the social media like microblog, blogs and social network have supplied a bunch of information with locations (Volunteered Geographical Information, VGI).Recent years many cases have shown that, if disaster happened, the cyber citizens will get together very quickly and share the disaster information, this results a bunch of volunteered geographical information about disaster situation which is very valuable for disaster response if this VGIs are used efficiently and properly. This project will take typhoon disaster as case study. In this paper, we study the relations between weibo messages and the real typhoon situation, we proposed an analysis framework for mine the relations between weibo messages distribution and physical space. We found that the number of the weibo messages, key words frequency and spatial temporary distribution of the messages have strong relations with the disaster spread in the real world, and this research results can improve our disaster situation awareness in the future. The achievement of the study will give a method for typhoon disaster situation awareness based on VGI from the bottom up, and will locate the disaster spot and evolution quickly which is very important for disaster response and recover.

Congestive heart failure, spouses' support and the couple's sleep situation: a critical incident technique analysis.

Science.gov (United States)

Broström, Anders; Strömberg, Anna; Dahlström, Ulf; Fridlund, Bengt

2003-03-01

Sleep related breathing disorders are common as well as a poor prognostic sign associated with higher mortality in patients with congestive heart failure (CHF). These patients often have a shorter total duration of sleep, disturbed sleep structure and increased daytime sleepiness, which can negatively affect all dimensions of the life situation. The spouse has an important role in supporting the patient in relation to sleep disorders, but this role may be adversely affected by the sleep situation of the couple. The aim of this study was to describe decisive situations that influence spouses' support to patients with CHF in relation to the couple's sleep situation. A qualitative descriptive design using critical incident technique was employed. Incidents were collected by means of interviews with 25 spouses of patients with CHF, strategically selected from two hospital-based specialist clinics in southern Sweden. Two main areas emerged in the analysis: support stimulating situations and support inhibiting situations. Support stimulating situations described how spouses' support was positively affected by their own adaptation in psychosocial or practical situations, and receiving help from others. Support inhibiting situations described how the spouses' support was negatively affected by sleep disturbances as a result of the patient's symptoms, anxiety in relation to the disease, limitations as a result of the sleeping habits, dissatisfaction with care related to the sleep situation, and being left to cope alone with the problems. An increased understanding of the stimulating and inhibiting situations influencing spouses' support for patients with CHF can guide health care personnel in deciding if an intervention is needed to improve the sleep situation for patient and spouse.

Education as an income situation determinant of a consumer

Directory of Open Access Journals (Sweden)

Ladislav Stejskal

2010-01-01

Full Text Available The article is focused on an analysis of educational attainment of an individual and income ­situation of their household. At the beginning, a compendious summary of secondary sources is introduced. It resumes data supporting and contradicting the hypothesis about education as a determinant of an income situation. The preliminary theses analysis is performed by results quantification of a project called European Union – Statistics on Income and Living Conditions (EU-SILC. Aim of the paper is to verify the input thesis assumed from secondary resources. The thesis concerns the direct ­proportion between a level of education achieved and level of financial income. An introduction of a methodolo­gy and research summarized data forms a basis for particular analyses which are based on a conjunction of obtained information on household average monthly income and the educational attainment of their leading member. Analyses are sustained by contingency which characteri­zes social groups, i.e. spheres in which leading members are mostly involved with regard to income.Research results proved the validity of the preliminary thesis about correlation, respectively direct proportionality of educational attainment and monthly income amount. Education is consequently identified as one of income situation determinants. The authors anticipate specificity of the selected point of view. Results are therefore presented only as a partial argument and a possible base for further enquiries.

Theory-practice integration in selected clinical situations

2001-09-01

Full Text Available The current changes in health care systems challenge knowledgeable, mature and independent practitioners to integrate theoretical content with practice. The aim of this study was to investigate the problems of integrating theory with practice in selected clinical nursing situations. The study focused on rendering of family planning services to clients as a component of Community Nursing Science. Structured observation schedules were used to observe the theoretical content of the curriculum as well as the practical application of what has been taught in the clinical area. The findings of the study revealed that there was a need for an integrated holistic curriculum, which would address the needs of the community. It was concluded that a problem-based and community-based curriculum, intersectoral collaboration between college and hospital managements and student involvement in all processes of teaching and learning would improve the integration of theory and practice. There also appeared to be a need for tutors to be more involved in clinical teaching and accompaniment.

An abnormal situation modeling method to assist operators in safety-critical systems

International Nuclear Information System (INIS)

Naderpour, Mohsen; Lu, Jie; Zhang, Guangquan

2015-01-01

One of the main causes of accidents in safety-critical systems is human error. In order to reduce human errors in the process of handling abnormal situations that are highly complex and mentally taxing activities, operators need to be supported, from a cognitive perspective, in order to reduce their workload, stress, and the consequent error rate. Of the various cognitive activities, a correct understanding of the situation, i.e. situation awareness (SA), is a crucial factor in improving performance and reducing errors. Despite the importance of SA in decision-making in time- and safety-critical situations, the difficulty of SA modeling and assessment means that very few methods have as yet been developed. This study confronts this challenge, and develops an innovative abnormal situation modeling (ASM) method that exploits the capabilities of risk indicators, Bayesian networks and fuzzy logic systems. The risk indicators are used to identify abnormal situations, Bayesian networks are utilized to model them and a fuzzy logic system is developed to assess them. The ASM method can be used in the development of situation assessment decision support systems that underlie the achievement of SA. The performance of the ASM method is tested through a real case study at a chemical plant. - Highlights: • Bayesian networks are applied to represent operators’ mental models when confront with abnormal situations. • A fuzzy logic system is used to resemble operators’ generating assessment results for every abnormal situation. • A virtual plant user interface and a prototype based on proposed method are developed to simulate a real case

Training Inference Making Skills Using a Situation Model Approach Improves Reading Comprehension

2016-02-01

Full Text Available This study aimed to enhance third and fourth graders’ text comprehension at the situation model level. Therefore, we tested a reading strategy training developed to target inference making skills, which are widely considered to be pivotal to situation model construction. The training was grounded in contemporary literature on situation model-based inference making and addressed the source (text-based versus knowledge-based, type (necessary versus unnecessary for (re-establishing coherence, and depth of an inference (making single lexical inferences versus combining multiple lexical inferences, as well as the type of searching strategy (forward versus backward. Results indicated that, compared to a control group (n = 51, children who followed the experimental training (n = 67 improved their inference making skills supportive to situation model construction. Importantly, our training also resulted in increased levels of general reading comprehension and motivation. In sum, this study showed that a ‘level of text representation’-approach can provide a useful framework to teach inference making skills to third and fourth graders.

It Takes More Than Two To TANGO: Co-Constructing Situated Accountability Through a Local E-Government Arena

2004-04-01

Full Text Available This paper deals with the issue of shaping local egovernment policies and practices, by including several actors, such as researchers, official authorities, politicians and software companies as well as ordinary citizens in a joint, sustainable development of a region. One way to provide space and place for this ongoing coconstruction and negotiation work of situated egovernment is the establishment of a regional center of competence on e-government, within a program, partly funded by the European Commission, called Innovative Actions. TANGO (Thematic Arenas Nourish Growth Opportunities is a way to build thematic competence centres and stimulate local research- and development projects (R&D, carried out in co-operation with partners from local business life. The Come on in- project, described in this paper, is an example of such an R&D project. The practices reveal several critical and crucial negotiation situations that are of importance to be put forward and be discussed in relation to what situated accountability could mean for the development of what could be called a new politics production. Situated accountability is therefore of great significance for this discussion.

Russell, Anthony P

2009-09-01

The current challenges (increasing levels of integration in the biological sciences) facing the teaching of zoology and the structure of the zoology curriculum are explored herein. General context is provided and a more focused scrutiny of the situation in North America is presented. The changing emphases in more broadly-based biological sciences programs in North America are outlined, and their influence on the role of zoology as part of fundamental biological training is considered. The longer term impact of such changes in emphasis on the teaching of zoology is discussed, and the central role that zoology can play in dealing with both science content and science education is advanced. Based upon a focal workshop on the future of the zoology curriculum in Canada, a perspective on the challenges facing curriculum evolution is provided. Extensive curriculum redesign is called for to ensure that zoology provides a broad-scale integrative approach to the understanding of biodiversity in evolutionary, ecological and functional contexts. Barriers to, and drivers of change are identified and the need for collaborative approaches to curricular evolution is emphasized. © 2009 ISZS, Blackwell Publishing and IOZ/CAS.

[Support psychotherapy in traumatic situations].

Science.gov (United States)

Pérez-Sales, Pau; Vázquez Valverde, Carmelo

2003-12-01

It seems that a certain consensus exists to speak about a traumatic situation as an experience which is made up of a threat on the physical or psychological integrity of a person and against which one responds with fear, desperation and intensive horror. Different psychological phenomena are involved with the manner through which a human being confronts his/her past. In particular, the response to traumatic situations, mourning, and blame share their characteristic of being an irreversible living reality related to facts, loss or past impacts and it is necessary to integrate these in one's life in order to advance; these comprise a triangle frequently coexisting and interconnected. Aid for these three situations has, therefore, as common elements, two premises: an active task is required by the person who suffers this situation; this person must, in some form, desire to move ahead. One can not toil in mourning, in a traumatic experience, or in a life of blame if these have a positive symbolic value for this person; for example, mourning as a manner not to treason the dead person by forgetting that person, the reliving a trauma as an attempt to provide some sense to the actions which occurred, or blame as a desire to not forget an error or as a final punishment of this active task; the final objective of this active task is not usually to forget but to integrate in order to live. If a person does not perceive this clearly, this person may not become actively involved in the task to overcome a traumatic situation and to move ahead, nor will that person accept that a person who tries to help questions this person's realities or experiences.

Strengthening rehabilitation services in Indonesia: A brief situation analysis.

2018-04-18

People with disability (PWD) in Indonesia are often neglected by society. Improving their life situation towards full participation in society is crucial. As a health strategy, rehabilitation can improve func-tioning, quality of life and participation in society. However, rehabilitation services in Indonesia need improvement. Making a situation analysis of rehabilitation services and their provision in the country is a pre-requisite to taking any action towards improvement. This paper compiles available data related to disability and rehabilitation services in Indonesia, using the Rehabilitation Services Assessment Tool (RSAT) as a framework. Gaps in provision were analysed, resulting in the compilation of a list of generic recommendations to improve rehabilitation services in the country. Indonesia faces many challenges in rehabilitation services, including the health workforce and the provision of services. This situation analysis and list of generic recommendations may be used in further discussions with relevant stakeholders in the country to develop a national strategy to strengthen rehabilitation services.

Sexual interaction or a solitary action: young Swedish men's ideal images of sexual situations in relationships and in one-night stands.

Elmerstig, Eva; Wijma, Barbro; Sandell, Kerstin; Berterö, Carina

2014-10-01

It seems that traditional gender norms influence young women's and men's sexuality differently. However, little attention has been paid to ideal images of sexual situations. This study identifies young heterosexual men's ideal images of sexual situations and their expectations of themselves in sexual situations. The present study employs a qualitative design. Twelve Swedish men (aged 16-20) participated in individual in-depth qualitative interviews. The interviews were transcribed verbatim and analysed using the constant comparative method from grounded theory. Our study revealed that the young men's conceptions of normal sexual situations were divided into two parts: sexual situations in relationships, and sexual situations in one-night stands. Their ideal image, "a balanced state of emotional and physical pleasure", was influenced by the presence/absence of intimacy, the partner's response, and their own performance. The greatest opportunities to experience intimacy and the partner's response were found during sexual situations in relationships. In one-night stands, the men wanted to make a good impression by performing well, and behaved according to masculine stereotypes. Stereotyped masculinity norms regulate young heterosexual men's sexuality, particularly in one-night stands. Sexual health promotion should emphasize the presence of these masculinity norms, which probably involve costs in relation to young men's sexual wellbeing. Copyright © 2014 Elsevier B.V.

Geriatric oncology (GO) is a discipline that focuses on the management of elderly patients with cancer. The Spanish Society of Medical Oncology (SEOM) created a Working group dedicated to geriatric oncology in February 2016. The main goal of this study was to describe the current situation in Spain regarding the management of elderly cancer patients through an online survey of medical oncologists. A descriptive survey was sent to several hospitals by means of the SEOM website. A personal e-mail was also sent to SEOM members. Between March 2016 and April 2017, 154 answers were collected. Only 74 centers (48%) had a geriatrics department and a mere 21 (14%) medical oncology departments had a person dedicated to GO. The vast majority (n = 135; 88%) had the perception that the number of elderly patients with cancer seen in clinical practice had increased. Eighteen (12%) oncologists had specific protocols and geriatric scales were used at 55 (31%) centers. Almost all (92%) claimed to apply special management practices using specific tools. There was agreement that GO afforded certain potential advantages. Finally, 99% of the oncologists surveyed believed it and that training in GO had to be improved. From the nationwide survey promoted by the Spanish Geriatric Oncology Working Group on behalf of SEOM, we conclude that there is currently no defined care structure for elderly cancer patients. There is an increasing perception of the need for training in GO. This survey reflects a reality in which specific needs are perceived.

College students were randomly assigned to the group of positive, negative or neutral music. Participants filled out the positive and negative affect schedule (PANAS) before and after carrying out the Corsi Test and the Walking Corsi Test. Both tasks were performed forward and backward. Music was played throughout the memory tasks. Firstly, comparing pre-mood induction PANAS scores to post-mood induction PANAS scores, results showed that only positive affects were manipulated: After mood induction, the Positive Music Group produced higher scores, whereas the Negative Music Group produced lower scores than before mood induction; the Neutral Music Group produced no effect. Secondly, the Positive Music Group produced higher scores than Negative and Neutral Music Groups both at the Corsi Test and at the Walking Corsi Test. These results show that situational contexts that induce a specific mood can affect visuospatial memory and navigational working memory, and open to the idea that positive emotions may play a crucial role in enhancing navigational strategies.

The layperson's qualification to provide early care in emergency situations and basic life support (BLS) is fundamental to save lives and prevent sequels. The objective was to identify the level of knowledge of lay people about approaching an emergency victim. Structured interviews in non-technical language were used with a 385-subject sample, average age 35.4 (+/- 14.55) years, with more than 50% having a high school or university education. Over 55% of these observed situations with loss of...

A situation-response model for intelligent pilot aiding

Science.gov (United States)

Schudy, Robert; Corker, Kevin

1987-01-01

An intelligent pilot aiding system needs models of the pilot information processing to provide the computational basis for successful cooperation between the pilot and the aiding system. By combining artificial intelligence concepts with the human information processing model of Rasmussen, an abstraction hierarchy of states of knowledge, processing functions, and shortcuts are developed, which is useful for characterizing the information processing both of the pilot and of the aiding system. This approach is used in the conceptual design of a real time intelligent aiding system for flight crews of transport aircraft. One promising result was the tentative identification of a particular class of information processing shortcuts, from situation characterizations to appropriate responses, as the most important reliable pathway for dealing with complex time critical situations.

2015-01-01

Visual perception and eye movements are considered to be tightly linked. Diverse fields, ranging from developmental psychology to computer science, utilize eye tracking to measure visual perception. However, this prevailing view has been challenged by recent behavioral studies. We review converging evidence revealing dissociations between the contents of perceptual awareness and different types of eye movements. Such dissociations reveal situations in which eye movements are sensitive to part...

Hable, K.; Hoebler, C.; Bieringer, P.

2007-01-01

In the field of precautionary radiation protection and disaster response, the amount of information and the number of its sources is steadily increasing. Central compilation and instant availability of information for all involved authorities becomes more and more important. In this context the structured presentation of documents on a web server in terms of an ''Electronic Situation Display'' (ESD) has been established. In Germany, there are several Electronic Situation Display prototypes run by federal and state authorities for various purposes and using different technical approaches. The systems of the federal states focus on workflow management. They provide emergency log books and information on the implementation of countermeasures for disaster response authorities. The Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU) tasked the Federal Office for Radiation Protection (BfS) to develop the Federal Electronic Situation Display (ELAN) that is mainly used as an information platform for decision making in case of nuclear emergencies. Documents containing radiological data or results from Decision Support Systems are almost automatically integrated into ELAN. Read and write permissions for users are managed by a concept of specific roles. The federal ESD and the systems of the federal states will be coordinated in order to achieve a better harmonisation. Interfaces for data exchange and data processing must be defined. Authorities of the federal states can use protected areas within the federal ESD where information is kept confidential for internal use before it is distributed to other states and federal authorities. In addition, key information of Electronic Situation Displays from the federal states can automatically be integrated into ELAN. Several task groups of the IAEA are working on the development and realization of a prototype for an information platform harmonising ESDs on international level. (orig.)

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.

Evolutionary psychology holds such an opinion that negative situation may threaten survival, trigger avoidance motive and have poor effects on the human-body function and the psychological quality. Both disgusted and sad situations can induce negative emotions. However, differences between the two situations on attention capture and emotion cognition during the emotion induction are still not well known. Typical disgusted and sad situation images were used in the present study to induce two negative emotions, and 15 young students (7 males and 8 females, aged 27 ± 3) were recruited in the experiments. Electroencephalogram of 32 leads was recorded when the subjects were viewing situation images, and event-related potentials (ERP) of all leads were obtained for future analysis. Paired sample t tests were carried out on two ERP signals separately induced by disgusted and sad situation images to get time quantum with significant statistical differences between the two ERP signals. Root-mean-square deviations of two ERP signals during each time quantum were calculated and the brain topographic map based on root-mean-square deviations was drawn to display differences of two ERP signals in spatial. Results showed that differences of ERP signals induced by disgusted and sad situation images were mainly manifested in T1 (120-450 ms) early and T2 (800-1,000 ms) later. During the period of T1, the occipital lobe reflecting attention capture was activated by both disgusted and sad situation images, but the prefrontal cortex reflecting emotion sense was activated only by disgusted situation images. During the period of T2, the prefrontal cortex was activated by both disgusted and sad situation images. However, the parietal lobe was activated only by disgusted situation images, which showed stronger emotional perception. The research results would have enlightenment to deepen understanding of negative emotion and to exploredeep cognitive neuroscience mechanisms of negative

Human Factors for Situation Assessment in Grid Operations

Energy Technology Data Exchange (ETDEWEB)

Guttromson, Ross T.; Schur, Anne; Greitzer, Frank L.; Paget, Mia L.

2007-08-08

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.

Beyond pleasure and pain: Facial expression ambiguity in adults and children during intense situations.

According to psychological models as well as common intuition, intense positive and negative situations evoke highly distinct emotional expressions. Nevertheless, recent work has shown that when judging isolated faces, the affective valence of winning and losing professional tennis players is hard to differentiate. However, expressions produced by professional athletes during publicly broadcasted sports events may be strategically controlled. To shed light on this matter we examined if ordinary people's spontaneous facial expressions evoked during highly intense situations are diagnostic for the situational valence. In Experiment 1 we compared reactions with highly intense positive situations (surprise soldier reunions) versus highly intense negative situations (terror attacks). In Experiment 2, we turned to children and compared facial reactions with highly positive situations (e.g., a child receiving a surprise trip to Disneyland) versus highly negative situations (e.g., a child discovering her parents ate up all her Halloween candy). The results demonstrate that facial expressions of both adults and children are often not diagnostic for the valence of the situation. These findings demonstrate the ambiguity of extreme facial expressions and highlight the importance of context in everyday emotion perception.

2012-01-01

To investigate the accuracy of defining characteristics of Situational low self-esteem we developed a cross-sectional study, with 52 pregnant women assisted in a family centre. The NANDA-I taxonomy was used as well as the Rosenberg's scale. The diagnosis was present in 32.7% of the sample and all characteristics presented statistical significance, except "Reports verbally situational challenge to its own value". The characteristics "Indecisive behavior" and "Helplessness expressions" had 82.35% of sensitivity. On the other hand, the characteristics "Expression of feelings of worthlessness" and "Reports verbally situational challenge to its own value" were the more specific, with 94.29% of specificity. These results can contribute with the nursing practice because the identification of accurate characteristics is essential to a secure inference.

Measuring strategy in case of a nuclear emergency situation

International Nuclear Information System (INIS)

Bieringer, J.; Bieringer, P.

2003-01-01

In the case of a nuclear emergency situation there are other demands -compared to normal operation - of kind, availability in time and volume of information providing the description of the radiological situation and allowing the recommendation of countermeasures in time. These requirements depend on the different phases of the emergency situation and the intense operation, respectively. In the first phase e. g. even before the radioactive release starts, information from the nuclear power plant is needed besides weather forecasts, trajectories and prognoses about the expected external dose and the contamination. In addition fast available results from dose rate measurements and information about the radionuclide spectrum are necessary. The aim is to get an overview about the actual radiological situation and its possible development in time in order to introduce countermeasures, where necessary. In the second phase, short time after the distribution of the radioactive substances has stopped, measurements according to Paragraph 3 of the precautionary radiation protection law (StrVG) are of primary interest, especially the determination of the contamination of human food and animal feed. In this phase after the end of the deposition process, where the spectrum of the deposited radionuclides is known, the behaviour of the external dose as a function of time can be well predicted. In the third phase, this means weeks after the emergency situation, the measurements are used to observe the activity concentrations in different media on a long time scale. In the beginning (phase one and two) the availability of information in time is of great importance. With increasing time this shifts more and more to the diversity of the analysed media. (orig.)

Argumentation functions in solving conflicting situations of social interaction in students of different age

T.V. Morozova

2013-10-01

Full Text Available The paper describes the results of a study of functions of argumentation in solving conflicting situations of social interaction, with the participation of younger students (III and IV grade, middle school students (V and VII grade and high school students (X classes, 211 students overall. The starting point of the research was the idea that distress occurring in a contradictory situation, does not relieve externally, but requires a structural analysis of the situation and a decision from the subject. The hypothesis of the study was the assumption that the argument used by the subject in a situation, can have opposite functions: a real change in the situation or a formal removal of contradictions in order to reduce stress. The author notes that overcoming the contradictions is linked inevitably to the need to clarify the rules of interaction between the parties, and this in turn puts the subject under certain psychological risk (the risk of criticism, disapproval or punishment, the risk of loss of secondary benefits of ambiguous situation, etc. that impede productive action in a contradictory situation.

Neural correlates reveal sub-lexical orthography and phonology during reading aloud: A review

Directory of Open Access Journals (Sweden)

Kalinka eTimmer

2014-08-01

Full Text Available The sub-lexical conversion of graphemes-to-phonemes (GPC during reading has been investigated extensively with behavioral measures, as well as event-related potentials (ERPs. Most research utilizes silent reading (e.g., lexical decision task for which phonological activation is not a necessity. However, recent research employed reading aloud to capture sub-lexical GPC. The masked priming paradigm avoids strategic processing and is therefore well suitable for capturing sub-lexical processing instead of lexical effects. By employing ERPs, the on-line time course of sub-lexical GPC can be observed before the overt response. ERPs have revealed that besides phonological activation, as revealed by behavioral studies, there is also early orthographic activation. This review describes studies in one’s native language, in one’s second language, and in a cross-language situation. We discuss the implications the ERP results have on different (computational models. First, the ERP results show that computational models should assume an early locus of the grapheme-to-phoneme-conversion (GPC. Second, cross-language studies reveal that the phonological representations from both languages of a bilingual become activated automatically and the phonology belonging to the context is selected rapidly. Therefore, it is important to extend the scope of computational models of reading (aloud to multiple lexicons.

Managing Reputation Risk and Situational Crisis in Higher Institutions of Learning

Full Text Available Extant literature on crisis and corporate reputation management has presented the Situational Crisis Communication Theory (SCCT model as a valid and reliable framework for managing crisis and predicting stakeholders’perceptions of organizations’ reputation in times of crisis. In order to verifythe applicability of the model in higher institutions of learning in adeveloping country context, a study was conducted in September, 2011 in twopublic universities in Nigeria. The findings of the study revealed thatalthough the institutions did not fully implement the core tenets of SCCT, thestrategies adopted in each of the two crisis situations were similar to some ofthe recommendations of the SCCT in different ways. While one institutionfocused on a strategy similar to what the SCCT model describes as “rebuildcrisis response strategy” with informing and adjusting tactics, the secondinstitution utilized a victimization or “Victimage” strategy with strongattribution of blames; and frequent reminder of the stakeholders of the extentof losses that the institution would incur from the crisis. The outcome wasthat the institution with high emphasis on rebuilding and informationadjustment strategy recorded very little damage to its reputation capital, duringand after the crises. Conversely, the second institution which believed invictimization and high attribution recorded significant losses in reputation assets,which included withdrawal of key stakeholders and loss of recognition ofprograms by some professional agencies. The implication for crisis managers in thetwo institutions includes the need to always approach situational crises in aholistic manner. Such holistic approach would involve a refocus, critical analysis,planning and implementation of crisis response strategies based on the relevantsituations, events, and the people concerned. The research was designed as acase study with focus group discussions as the data collection method

2014-01-01

The different epidemiological situation of tuberculosis in various regions of Poland (higher and lower notification rates) was described previously by our group. The patients diagnosed with tuberculosis in the higher notification rate areas were younger and there were more cases of primary tuberculosis (tuberculous pleurisy and tuberculosis of chest lymph nodes) than in the patients diagnosed in the lower notification areas. The aim of the present study was to assess the possible causes of the different epidemiological situation of tuberculosis in various regions of Poland. Analysis was done at the same regions as in the previous paper. A comparison was made between two groups: Group I, which included three voivodeships with higher rates of notification, from 23.7 to 32.3/100,000 (mean rates in the analysed period of time); and Group II, which included five voivodeships with lower notification rates (mean rates from 12.2 to 18.6/100,000). The wealth of the regions (GDP, gross domestic product per capita), the level of unemployment, and social status of the patients were analysed. We compared the population density in both regions. The results of treatment in both regions were also analysed. We did not find any differences in GDP and unemployment rates between the compared regions. The results of treatment were different in particular regions, but there was no clear tendency for worse results in voivodeships in Group I compared to voivodeships in Group II. However, the number of patients lost from observation was significantly higher in the regions from Group I than in those from Group II. There was also a significantly higher death rate from tuberculosis in younger patients (£ 59 years) from Group I than from Group II. This is additional proof that the epidemiological situation in the two regions was different. Finally, we found that the mean density of population in the regions from Group I was higher than that from Group II. The density of population may

The Latent Class Model as a Measurement Model for Situational Judgment Tests

2011-11-01

Full Text Available In a situational judgment test, it is often debatable what constitutes a correct answer to a situation. There is currently a multitude of scoring procedures. Establishing a measurement model can guide the selection of a scoring rule. It is argued that the latent class model is a good candidate for a measurement model. Two latent class models are applied to the Managing Emotions subtest of the Mayer, Salovey, Caruso Emotional Intelligence Test: a plain-vanilla latent class model, and a second-order latent class model that takes into account the clustering of several possible reactions within each hypothetical scenario of the situational judgment test. The results for both models indicated that there were three subgroups characterised by the degree to which differentiation occurred between possible reactions in terms of perceived effectiveness. Furthermore, the results for the second-order model indicated a moderate cluster effect.

Situation and person attributions under spontaneous and intentional instructions: an fMRI study.

Science.gov (United States)

Kestemont, Jenny; Vandekerckhove, Marie; Ma, Ning; Van Hoeck, Nicole; Van Overwalle, Frank

2013-06-01

This functional magnetic resonance imaging (fMRI) research explores how observers make causal beliefs about an event in terms of the person or situation. Thirty-four participants read various short descriptions of social events that implied either the person or the situation as the cause. Half of them were explicitly instructed to judge whether the event was caused by something about the person or the situation (intentional inferences), whereas the other half was instructed simply to read the material carefully (spontaneous inferences). The results showed common activation in areas related to mentalizing, across all types of causes or instructions (posterior superior temporal sulcus, temporo-parietal junction, precuneus). However, the medial prefrontal cortex was activated only under spontaneous instructions, but not under intentional instruction. This suggests a bias toward person attributions (e.g. fundamental attribution bias). Complementary to this, intentional situation attributions activated a stronger and more extended network compared to intentional person attributions, suggesting that situation attributions require more controlled, extended and broader processing of the information.

Vulnerability Situations associated with Flash Flood Casualties in the United States

Terti, G.; Ruin, I.; Anquetin, S.; Gourley, J. J.

2015-12-01

In the United States (U.S.) flash flooding (FF hereafter) is one of the leading cause of weather-related deaths. Because FF events can be distinguished from riverine floods by their fast response to rainfall and resulting impacts signature, analyzing FF-specific impact datasets seems a good way to identify the juxtaposition of social and physical circumstances leading to those impacts. This communication focuses on conceptual and methodological developments allowing testing hypotheses on FF-specific vulnerability factors through the analysis of human impact datasets. We hypothesize that the intersection of the spatio-temporal context of the FF phenomena with the distribution of people and their characteristics across space and time reveals various paths of vulnerability through the expression of different accidents' circumstances (i.e., vehicle-related, inside buildings, open-air, campsites). We argue that vulnerability and the resulting impacts vary dynamically throughout the day according to the location/situation under concern. In order to test FF-specific contextual vulnerability factors at the scale of the continental US, 1075 fatalities reported between 1996 and 2014 in the Storm Data publication of the U.S. National Climatic Data Center (NCDC) are analyzed to statistically explore the timing, the duration and the location of the FF event, and the age and gender of the victims and the circumstance (i.e. location/activity) of their death. In this objective, a re-classification of the individual fatality circumstances and a discretization of the time in qualitative time-steps are performed to obtain possible trends and patterns in the occurrence of fatalities in certain circumstances and time (e.g., day vs night). The findings highlight the importance of situation-specific assessment of FF fatalities to guide the development of FF-specific vulnerability and impacts prediction modeling. Such analysis can provide valuable knowledge when the National Weather

Understanding situation awareness and its importance in patient safety.

Gluyas, Heather; Harris, Sarah-Jane

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.

Effective teamwork in ED resuscitations, including information sharing and situational awareness, could be degraded. Technological cognitive aids can facilitate effective teamwork. This study focused on the design of an ED situation display and pilot test its influence on teamwork and situational awareness during simulated resuscitation scenarios. The display design consisted of a central area showing the critical dynamic parameters of the interventions with an events time-line below it. Static information was placed at the sides of the display. We pilot tested whether the situation display could lead to higher scores on the Clinical Teamwork Scale (CTS), improved scores on a context-specific Situational Awareness Global Assessment Technique (SAGAT) tool, and team communication patterns that reflect teamwork and situational awareness. Resuscitation teamwork, as measured by the CTS, was overall better with the presence of the situation display as compared with no situation display. Team members discussed interventions more with the situation display compared with not having the situation display. Situational awareness was better with the situation display only in the trauma scenario. The situation display could be more effective for certain ED team members and in certain cases. Overall, this pilot study implies that a situation display could facilitate better teamwork and team communication in the resuscitation event. Copyright © 2017 Elsevier Inc. All rights reserved.

Fathers in situational crisis: a comparison of Asian and Western cultures.

Science.gov (United States)

Tseng, Yun-Shan; Verklan, M Terese

2008-09-01

The purpose of this synthesis was to compare the difference between Asian and Western fathers' perceptions of their roles when confronted with situational crises involving their children. Twenty-two studies were reviewed and assigned to one of two categories: the father experiencing a situational crisis related to his child's illness or cultural influences on the paternal role. The results indicated that Asian and Western fathers' perceptions of crises do not differ greatly. It was concluded that there exists a gap in the literature with respect to the knowledge of Asian fathers' situational crisis surrounding their child's illness, their coping strategies when faced with their child's illness, as well as their emotional reactions toward family health. Future research should investigate the single or same-gender father's perceptions and emotional reactions in both Asian and Western cultures.

Representing and reasoning about program in situation calculus

Yang, Bo; Zhang, Ming-yi; Wu, Mao-nian; Xie, Gang

2011-12-01

Situation calculus is an expressive tool for modeling dynamical system in artificial intelligence, changes in a dynamical world is represented naturally by the notions of action, situation and fluent in situation calculus. Program can be viewed as a discrete dynamical system, so it is possible to model program with situation calculus. To model program written in a smaller core programming language CL, notion of fluent is expanded for representing value of expression. Together with some functions returning concerned objects from expressions, a basic action theory of CL programming is constructed.

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.

Situational avoidance is a form of driving self-regulation at the strategic level of driving behaviour. It has typically been defined as the purposeful avoidance of driving situations perceived as challenging or potentially hazardous. To date, assessment of the psychometric properties of existing scales that measure situational avoidance has been sparse. This study examined the contribution of Rasch analysis to the situational avoidance construct. Three hundred and ninety-nine Australian drivers (M=66.75, SD=10.14, range: 48-91 years) completed the Situational Avoidance Questionnaire (SAQ). Following removal of the item Parallel Parking, the scale conformed to a Rasch model, showing good person separation, sufficient reliability, little disordering of thresholds, and no evidence of differential item functioning by age or gender. The residuals were independent supporting the assumption of unidimensionality and in conforming to a Rasch model, SAQ items were found to be hierarchical or cumulative. Increased avoidance was associated with factors known to be related to driving self-regulation more broadly, including older age, female gender, reduced driving space and frequency, reporting a change in driving in the past five years and poorer indices of health (i.e., self-rated mood, vision and cognitive function). Overall, these results support the use of the SAQ as a psychometrically sound measure of situational avoidance. Application of Rasch analysis to this area of research advances understanding of the driving self-regulation construct and its practice by drivers in baby boomer and older adult generations.

Situation awareness (SA) constitutes a critical factor in road safety, strongly related to accidents. This paper describes the evaluation of a proposed SA enhancement system (SAES) that exploits augmented reality through a head-up display (HUD). Two SAES designs were evaluation (information rich vs. minimal information) using a custom-made simulator and the Situation Awareness Global Assessment Technique with performance and EEG measures. The paper describes the process of assessing the SA of drivers using the SAES, through a series of experiments with participants in a Cave Automatic Virtual Environment. The effectiveness of the SAES was tested in a within-group research design. The results showed that the information rich (radar-style display) was superior to the minimal (arrow hazard indicator) design and that both SAES improved drivers' SA and performance compared to the control (no HUD) design. Practitioner Summary: Even though driver situation awareness is considered as one of the leading causes of road accidents, little has been done to enhance it. The current study demonstrates the positive effect of a proposed situation awareness enhancement system on driver situation awareness, through an experiment using virtual prototyping in a simulator.

Situated learning theory: adding rate and complexity effects via Kauffman's NK model.

Science.gov (United States)

Yuan, Yu; McKelvey, Bill

2004-01-01

For many firms, producing information, knowledge, and enhancing learning capability have become the primary basis of competitive advantage. A review of organizational learning theory identifies two approaches: (1) those that treat symbolic information processing as fundamental to learning, and (2) those that view the situated nature of cognition as fundamental. After noting that the former is inadequate because it focuses primarily on behavioral and cognitive aspects of individual learning, this paper argues the importance of studying learning as interactions among people in the context of their environment. It contributes to organizational learning in three ways. First, it argues that situated learning theory is to be preferred over traditional behavioral and cognitive learning theories, because it treats organizations as complex adaptive systems rather than mere information processors. Second, it adds rate and nonlinear learning effects. Third, following model-centered epistemology, it uses an agent-based computational model, in particular a "humanized" version of Kauffman's NK model, to study the situated nature of learning. Using simulation results, we test eight hypotheses extending situated learning theory in new directions. The paper ends with a discussion of possible extensions of the current study to better address key issues in situated learning.

ABSTRACT. Given the voluntary nature of adolescent friendships, forgiveness of interpersonal transgressions has been identified as a critical aspect of maintaining these relationships. However, transgression forgiveness is related to a range of situational (e.g., transgression severity), interpersonal (e.g., friendship commitment), and intrapersonal (e.g., victim's empathy) factors. Data from 161 adolescents were used to examine the nature of the relationships between these factors and forgiveness and to examine the differential association patterns for adolescent boys and girls. Results for the overall adolescent sample indicated both situational and interpersonal factor associations with forgiveness (R2 = .52, p interpersonal factor associations and differential situational factor associations with female (R2 = .46, p < .001), and male (R2 = .60, p < .001) forgiveness. Findings suggest the likelihood of forgiving may be contextually dependent, and that researchers should consider transgression, relationship, and intrapersonal characteristics when examining forgiveness. Further, the present study suggests the contextual factors associated with forgiveness may be further differentiated by gender.

Sensitivity towards fear of electric shock in passive threat situations.

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.

Minimally invasive surgery has gained significantly in importance over the last decade due to the numerous advantages on patient-side. The surgeon has to adapt special operation-techniques and deal with difficulties like the complex hand-eye coordination, limited field of view and restricted mobility. To alleviate these constraints we propose to enhance the surgeon's capabilities by providing a context-aware assistance using augmented reality (AR) techniques. In order to generate a context-aware assistance it is necessary to recognize the current state of the intervention using intraoperatively gained sensor data and a model of the surgical intervention. In this paper we present the recognition of risk situations, the system warns the surgeon if an instrument gets too close to a risk structure. The context-aware assistance system starts with an image-based analysis to retrieve information from the endoscopic images. This information is classified and a semantic description is generated. The description is used to recognize the current state and launch an appropriate AR visualization. In detail we present an automatic vision-based instrument tracking to obtain the positions of the instruments. Situation recognition is performed using a knowledge representation based on a description logic system. Two augmented reality visualization programs are realized to warn the surgeon if a risk situation occurs.

Towards an ethical theory in disaster situations.

Science.gov (United States)

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.

Fundamental situations in teaching biology: The case of parthenogenesis

Directory of Open Access Journals (Sweden)

Robert Evans

2012-06-01

Full Text Available This theoretical paper considers the notion of fundamental situation in the sense of Brousseau’s theory of didactical situations. It introduces some precise elements of this theory in which a teacher provides an environment for student work that aims to enable students, through constructive inquiry, to acquire well defined pieces of scientific knowledge. Situations become fundamental if they not only allow, but force students to construct the target knowledge. A classical example from mathematics is presented, where the target knowledge is a theorem of plane geometry presented as a puzzle. Then a new fundamental situation in biology is described for parthenogenetic reproduction, which has recently turned out to occur in Komodo dragons. An explicit demand to generate and test hypotheses that could explain the given example of dragon reproduction, using authentic DNA data, is given to students. The paper concludes with an analysis of the extent to which this fundamental situation in biology is authentic to the theory of didactical situations.

A situational approach to the measurement of safety culture

International Nuclear Information System (INIS)

Semmer, N.; Regennass, A.

1997-01-01

Values and social norms are the main target of most approaches to the study of safety culture and many existing survey methodologies directly ask for these norms and values. However, a number of considerations point to the dangers of limiting the evaluation of safety culture to the analysis of these responses. Therefore the necessity is stressed to also consider how actual situations activate norms and behaviours. This relates to the fact that in any given situation both aspects of the appraisal of reality are present: the objective definition of the situation and its personal evaluation. The latter not only reflects the ''official'' norms and values but also ''basic underlying assumptions''. The situational approach introduced in this paper confronts people with situations which contain a dilemma with conflicting social norms and where various costs and benefits are associated with different types of behaviour. In addition, the prerequisites and limitations of the situational approach are discussed. (author). 9 refs, 1 fig

Situation and person attributions under spontaneous and intentional instructions: an fMRI study

Science.gov (United States)

Kestemont, Jenny; Vandekerckhove, Marie; Ma, Ning; Van Hoeck, Nicole

2013-01-01

This functional magnetic resonance imaging (fMRI) research explores how observers make causal beliefs about an event in terms of the person or situation. Thirty-four participants read various short descriptions of social events that implied either the person or the situation as the cause. Half of them were explicitly instructed to judge whether the event was caused by something about the person or the situation (intentional inferences), whereas the other half was instructed simply to read the material carefully (spontaneous inferences). The results showed common activation in areas related to mentalizing, across all types of causes or instructions (posterior superior temporal sulcus, temporo-parietal junction, precuneus). However, the medial prefrontal cortex was activated only under spontaneous instructions, but not under intentional instruction. This suggests a bias toward person attributions (e.g. fundamental attribution bias). Complementary to this, intentional situation attributions activated a stronger and more extended network compared to intentional person attributions, suggesting that situation attributions require more controlled, extended and broader processing of the information.

The present study proposes arousal as an important mechanism driving buying impulsiveness. We examined the effect of buying impulsiveness on arousal in non-shopping and shopping contexts. In an eye-tracking experiment, we measured pupil dilation while participants viewed and rated pictures of shopping scenes and non-shopping scenes. The results demonstrated that buying impulsiveness is closely associated with arousal as response to viewing pictures of shopping scenes. This pertained for hedonic shopping situations as well as for utilitarian shopping situations. Importantly, the effect did not emerge for non-shopping scenes. Furthermore, we demonstrated that arousal of impulsive buyers is independent from cognitive evaluation of scenes in the pictures. PMID:25489955

Existential vulnerability: toward a psychopathology of limit situations.

Science.gov (United States)

Fuchs, Thomas

2013-01-01

Jaspers' concept of limit situations seems particularly appropriate not only to elucidate outstanding existential situations in general, but also basic preconditions for the occurrence of mental disorders. For this purpose, the concept is first explained in Jaspers' sense and then related to an 'existential vulnerability' of mentally ill persons that makes them experience even inconspicuous events as distressing limit situations. In such situations, an otherwise hidden fundamental condition of existence becomes manifest for them, e.g. the fragility of one's own body, the inevitability of freedom, or the finiteness of life. This fundamental condition is found unbearable and, as a reaction, gives rise to mental illness. This concept of existential vulnerability is illustrated by some psychopathological examples. © 2013 S. Karger AG, Basel.

Rational group decision making in risk situations

International Nuclear Information System (INIS)

Yoon, M.H.

1987-01-01

Risk management has received increasing attention recently as methods of quantifying risk have been evolving. This is considered a legitimate tendency in the context of the entirety of risk evaluation which connotes both risk quantification and decisions making thereon. A risk-free society does not appear possible; neither could one have zero competing risks or cost versus benefit resulting out of a risk-abatement effort. What further complicates the risk-decision problem is that there exists more than a single decision maker, who claim their own interests associated with risk decision. Furthermore, their risk perceptions are not at all same that the threshold risk levels for a particular actions are varying. In this dissertation, a brief survey on existing action levels for various sort of risk situations including carcinogens, toxic chemicals, etc., is reported on, with emphasis on nuclear risk situation. A decision theoretic approach is then adopted in both individual and group-level risk management. For the purpose of exemplification, multiplicative utility theory is applied for nuclear power risk; attributes derived for this specific purpose are discussed

Situation-dependent repair of DNA damage in yeast

International Nuclear Information System (INIS)

von Borstel, R.C.; Hastings, P.J.

1985-01-01

The concept of channelling of lesions in DNA into defined repair systems has been used to explain many aspects of induced and spontaneous mutation. The channelling hypothesis states that lesions excluded from one repair process will be taken up by another repair process. This is a simplification. The three known modes of repair of damage induced by radiation are not equivalent modes of repair; they are, instead, different solutions to the problem of replacement of damaged molecules with new molecules which have the same informational content as those that were damaged. The mode of repair that is used is the result of the response to the situation in which the damage takes place. Thus, when the most likely mode of repair does not take place, then the situation changes with respect to the repair of the lesion; the lesion may enter the replication fork and be reparable by another route

Activities performed are task analysis, evaluation of the drivers use of information and interaction with the ATP system as well as analyses of stress, mental workload and work hours. Several methods are being used such as interviews, questionnaires, diaries, activity monitoring and videotapes. This paper gives an overview of the project as well as a short summary of the main results. Detailed results are presented in separate reports as started in the reference list. Some of the main results are that the drivers report severe problems concerning sleepiness on early morning shifts, problems with maintenance on vehicles, lack of information supporting the planning task as well as problems in understanding ATP functions. Two groups of drivers having a feed-back related as opposed to a feed-forward driving style could be identified. In conclusion there is a great need to perform more scientific studies of human factors and railway safety as well as to implement safety management programs including professional human factors competence in the railway industries.

differential emphasis on traits versus specific mediators in turn fosters different reactions to negative events. Several studies have shown that entity theorists of intelligence are more likely than incremental theorists to react helplessly in the face of failure. They are not only more likely to make negative judgments about their intelligence from the failures, but also more likely to show negative affect and behaviors. This helpless response pattern is cha-racterized by a lack of persistence, and performance decrements. In contrast, incremental theorists, who focus more on behavioral factors (eg effort, problem-solving strategies) as causes of negative achievement outcomes, tend to act on these mediators. They try harder and develop better strategies and continue to work. Some authors have tendency to consider implicit theories of intelligence as a disposition or a stable dimension. But in the last few years, several studies showed that people's theories are not fixed traits; they are beliefs that may be influenced. These studies also suggested that students use the two types of beliefs and that the context determines the choice between the two types of theories. According to these authors, the psychological state of the student depends on dispositional factors but also on situational factors. Thus, several studies have tried to demonstrate that it is possible to modify experimentally implicit theories of intelligence and subsequent cognitions and behaviors by modifying situational factors. Several studies have demonstrated that it was possible to induce students to adopt one of the two theories of intelligence by presenting them a scientific article that compelling argued for either an entity or an incremental view of intelligence. The results showed that participants who had received the entity theory induction exhibited more evidence of a helpless reaction to failure. These studies show that some of the judgments and reactions associated with implicit theories can be

Full Text Available The research aimed to explore the present situation of the internal quantitative efficiency of Sanhan community college, and to identify the annual cost per student and material waste resulting from failure and dropout. The study depended primarily on the method of restructuring the study life in order to measure the internal efficiency of quantitative indicators for the college.  This was done by building the chart structure of student flow, which allows calculating success rate, failure rate, and the dropout rate for each batch. This enabled the researchers to calculate the indicators of internal quantity efficiency and its level. The study results revealed that the educational system in Sanhan Community college has not reached the required standard, which impacted  the internal quantitative efficiency. In addition, the proportion of quantitative loss resulting from students’ failure and dropout was (50%. Some recommendations were also proposed in order to raise the efficiency and effectiveness level so as to reach the desired standard. Keywords: Internal quantity efficiency, Sanhan Community College, Yemen.

Full Text Available The search for ways and means of fostering and development of multiculturalism is now of great importance for the world community. Situational vocabulary was previously proposed by the author as an ICT tool for fostering and development of communicative competence in foreign language. They contain lexical structures used in specific communicative situations, as well as modern ICT tools (blogs, chats, forums, mail, etc. to supplement already gained data and to discuss the ways and situations of use of various linguistic constructions or meanings of the words. Further study of the possibilities and ways of application of the instrument showed that students are not able to choose a relevant form for certain situations, or they lack or do not know the appropriate words and expressions, both in native and in a foreign language. In addition, the incorrect use of certain words or expressions in the situation may be regarded by representatives of other cultures as rude or disrespectful. The peculiarity of the method offered by the author is based on the idea of using situational vocabularies for gaining information and study of various linguistic and cultural aspects of the host country and other countries. In addition, the interaction in the familiar for learners ICT space motivates them and increase the effectiveness of such activities.

Full Text Available Awareness of emerging situations in a dynamic operational environment of a robotic assistive device is an essential capability of such a cognitive system, based on its effective and efficient assessment of the prevailing situation. This allows the system to interact with the environment in a sensible (semiautonomous / pro-active manner without the need for frequent interventions from a supervisor.  In this paper, we report a novel generic Situation Assessment Architecture for robotic systems directly assisting humans as developed in the CORBYS project. This paper presents the overall architecture for situation assessment and its application in proof-of-concept Demonstrators as developed and validated within the CORBYS project. These include a robotic human follower and a mobile gait rehabilitation robotic system. We present an overview of the structure and functionality of the Situation Assessment Architecture for robotic systems with results and observations as collected from initial validation on the two CORBYS Demonstrators.

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.

Mental Simulation of Painful Situations Has an Impact on Posture and Psychophysiological Parameters

Full Text Available Embodiment is made possible by the ability to imagine ourselves in a particular situation (mental simulation. Postural changes have been demonstrated in response to painful situations, but the effect of an implicit instruction has not been studied. The present study was designed to record differential responses according to whether or not subjects were instructed to imagine themselves in a painful or non-painful situation. Painful stimuli and instructions to mentally simulate the displayed situation were hypothesized to induce postural changes that could be demonstrated by changes in the center of pressure (COP trajectory compared to viewing the same stimuli with no instructions. We hypothesized that mental simulation of a painful situation would induce embodiment of the emotional situation as reflected by posterior displacement of the COP and physiological responses as compared to passive observation of the same visual scene. Thirty-one subjects participated in this study while standing quietly on a posturographic platform with presentation of visual stimuli depicting scenes defining three experimental conditions (painful, non-painful and neutral situations for 12 s. Physiological measurements [heart rate (HR and electrodermal activity] and postural responses (COP displacements were recorded in response to the stimuli with or without instructions to imagine themselves in the situation. Time-course analyses (1 s sliding window were conducted for several postural parameters, HR and electrodermal response. An interaction effect (instruction × stimuli × time demonstrated that mental simulation induced posterior displacement of the mean position of the COP at different times during presentation of visual stimuli (4 s; 9–12 s. An effect of instruction was reported for HR (HR was higher in the mental simulation condition, while a stimulation effect was reported only for HR (lower for painful stimuli than for non-painful stimuli.

A common assumption in organizations is that information sharing improves situation awareness and ultimately organizational effectiveness. The sheer volume and rapid pace of information and communications received and readily accessible through computer networks, however, can overwhelm individuals, resulting in data overload from a combination of diverse data sources, multiple data formats, and large data volumes. The current conceptual framework of network enabled operations (NEO) posits that robust networking and information sharing act as a positive feedback loop resulting in greater situation awareness and mission effectiveness in military operations (Alberts and Garstka, 2004). We test this assumption in a large-scale, 2-week military training exercise. We conducted a social network analysis of email communications among the multi-echelon Mission Command staff (one Division and two sub-ordinate Brigades) and assessed the situational awareness of every individual. Results from our exponential random graph models challenge the aforementioned assumption, as increased email output was associated with lower individual situation awareness. It emerged that higher situation awareness was associated with a lower probability of out-ties, so that broadly sending many messages decreased the likelihood of attaining situation awareness. This challenges the hypothesis that increased information sharing improves situation awareness, at least for those doing the bulk of the sharing. In addition, we observed two trends that reflect a compartmentalizing of networked information sharing as email links were more commonly formed among members of the command staff with both similar functions and levels of situation awareness, than between two individuals with dissimilar functions and levels of situation awareness; both those findings can be interpreted to reflect effects of homophily. Our results have major implications that challenge the current conceptual framework of NEO. In

Situation awareness system for Canada

Science.gov (United States)

Hill, Andrew

1999-07-01

Situation awareness encompasses a knowledge of orders, plans and current knowledge of friendly force actions. Knowing where you are and being able to transmit that information in near real-time to other friendly forces provides the ability to exercise precise command and control over those forces. With respect to current command and control using voice methods, between 40 percent and 60 percent of Combat Net Radio traffic relates to location reporting of some sort. Commanders at Battle Group and below spend, on average, 40 percent of their total time performing position and navigation related functions. The need to rapidly transfer own force location information throughout a force and to process the received information quickly, accurately and reliably provides the rationale for the requirement for an automated situation awareness system. This paper describes the Situation Awareness System (SAS) being developed by Computing Devices Canada for the Canadian Department of National Defence as a component of the Position Determination and Navigation for Land Forces program. The SAS is being integrated with the Iris Tactical Command, Control, Communications System, which is also being developed by Computing Devices. The SAS software provides a core operating environment onto which command and control functionality can be easily added to produce general and specialist battlefield management systems.

[Current situation with abortion in Colombia: between illegality and reality].

Science.gov (United States)

González Vélez, Ana Cristina

2005-01-01

This article discusses the illegality of abortion in Colombia, situating this country within the 0.4% of the world population where abortion is completely banned. Absolute criminalization of abortion turns it into a public health matter and produces social inequality. The Colombian legislation has always disregarded women as individuals and as persons in full possession of their legal rights. In contrast to a comprehensive conceptualization of sexual and reproductive rights, the various abortion bills merely refer either to "morally unacceptable" situations such as pregnancy resulting from rape or to therapeutic motives. Contradictions between illegality and reality give rise to a public discourse that features rejection of abortion practices, in keeping with the prevailing stance of the ecclesiastic hierarchy, while in practice, and at the private level, people resort to voluntary interruption of pregnancy under conditions of safety and confidentiality, at least for women from the higher socioeconomic strata. This situation not only causes social inequality but also reflects how laws lose meaning and create the collective impression of being useless or unnecessary, thus undermining the state's governing role.

Background Advance directives (AD) are an important tool for documentation of patients' wishes and are therefore recommended to the elderly as well as patients with chronic diseases. However, there is no standardized procedure in Germany and no guideline for counseling patients who wish to write an AD with or without health care proxy. The aim of this study was to evaluate the care situation concerning the ADs and the role of the primary care physician in drafting the document Method We conducted semi-structured interviews with patients in primary care in North Rhine-Westphalia using a cross-sectional study design. Result Most of the 154 patients who were interviewed (average age: 58 years; 52% female) suffered from chronic diseases (79%), and about one-third (32%) already had an AD. Fear of "loss of autonomy" was the main reason for preparing an AD. Patients without AD were generally not opposed to the concept and named procrastination (43%) as the main reason for not having prepared one. The chance for preparing an AD increased by the factor 1.08 per life-year (Odds ratio (OR): 1.08; CI: 1.04-1.11). Patients with AD mostly got advice via the internet (22%), their primary care physicians (12%) and relatives (12%). Most patients were satisfied with their AD. Conclusion The majority of primary care patients do not make use of ADs. The primary care physicians play an important role in counseling and should motivate patients to complete ADs. Here, the establishment of quality standards would be desirable in the future. © Georg Thieme Verlag KG Stuttgart · New York.

Threat evaluation for impact assessment in situation analysis systems

Science.gov (United States)

Roy, Jean; Paradis, Stephane; Allouche, Mohamad

2002-07-01

Situation analysis is defined as a process, the examination of a situation, its elements, and their relations, to provide and maintain a product, i.e., a state of situation awareness, for the decision maker. Data fusion is a key enabler to meeting the demanding requirements of military situation analysis support systems. According to the data fusion model maintained by the Joint Directors of Laboratories' Data Fusion Group, impact assessment estimates the effects on situations of planned or estimated/predicted actions by the participants, including interactions between action plans of multiple players. In this framework, the appraisal of actual or potential threats is a necessary capability for impact assessment. This paper reviews and discusses in details the fundamental concepts of threat analysis. In particular, threat analysis generally attempts to compute some threat value, for the individual tracks, that estimates the degree of severity with which engagement events will potentially occur. Presenting relevant tracks to the decision maker in some threat list, sorted from the most threatening to the least, is clearly in-line with the cognitive demands associated with threat evaluation. A key parameter in many threat value evaluation techniques is the Closest Point of Approach (CPA). Along this line of thought, threatening tracks are often prioritized based upon which ones will reach their CPA first. Hence, the Time-to-CPA (TCPA), i.e., the time it will take for a track to reach its CPA, is also a key factor. Unfortunately, a typical assumption for the computation of the CPA/TCPA parameters is that the track velocity will remain constant. When a track is maneuvering, the CPA/TCPA values will change accordingly. These changes will in turn impact the threat value computations and, ultimately, the resulting threat list. This is clearly undesirable from a command decision-making perspective. In this regard, the paper briefly discusses threat value stabilization

Implementation synergies that exploit situational knowledge strategically

Quitzau, Maj-Britt; Petersen, Jens-Phillip

This paper illustrates how strategic and situated forms of knowledge may increase capacity to implement energy strategies in local urban development projects. Through analysis of front runner implementation projects, we show that the involved planners utilize situational learning processes...... strategically to develop more viable implementation trajectories. These findings resonate well with relational and network orienteered research in contemporary planning theory. In the selected case studies, we can see that planners deliberately seek to extend traditional planning approaches, like e.......g. regulation, with broader context‐specific learning processes. In doing so, we argue that – what we call – an implementation synergy is established by interlacing different forms of situational knowledge with strategic knowledge about how to reach a desired energy target. In conclusion, the paper identifies...

To validate the content of the NANDA-I nursing diagnosis of grieving in situations of perinatal loss. Using the Fehring's model, 208 Spanish experts were asked to assess the adequacy of the defining characteristics and other manifestations identified in the literature for cases of perinatal loss. The content validity index was 0.867. Twelve of the 18 defining characteristics were validated, seven as major and five as minor. From the manifestations proposed, "empty inside" was considered as major. The nursing diagnosis of grieving fits in content to the cases of perinatal loss according to experts. The results have provided evidence to support the use of the diagnosis in care plans for said clinical situation. © 2013 NANDA International.

Eyes wide shopped: shopping situations trigger arousal in impulsive buyers.

Directory of Open Access Journals (Sweden)

Benjamin G Serfas

Full Text Available The present study proposes arousal as an important mechanism driving buying impulsiveness. We examined the effect of buying impulsiveness on arousal in non-shopping and shopping contexts. In an eye-tracking experiment, we measured pupil dilation while participants viewed and rated pictures of shopping scenes and non-shopping scenes. The results demonstrated that buying impulsiveness is closely associated with arousal as response to viewing pictures of shopping scenes. This pertained for hedonic shopping situations as well as for utilitarian shopping situations. Importantly, the effect did not emerge for non-shopping scenes. Furthermore, we demonstrated that arousal of impulsive buyers is independent from cognitive evaluation of scenes in the pictures.

In this report we describe some runs made with the code FASES2. They concern different situations associated to fires originated by accidents in the transport of containers filled with UF6. Such situations have been inspired in cases taken from the current literature, and related to numerical modelling or experiments. We aim to consign the most relevant aspects of such runs, with the future purpose of comparing them with the predictions made with simpler lumped models. In such a way, it will be possible to calibrate the simple models with the results coming from detailed models. (author). 6 refs., 12 figs

Team performance modeling for HRA in dynamic situations

Shu Yufei; Furuta, Kazuo; Kondo, Shunsuke

2002-01-01

This paper proposes a team behavior network model that can simulate and analyze response of an operator team to an incident in a dynamic and context-sensitive situation. The model is composed of four sub-models, which describe the context of team performance. They are task model, event model, team model and human-machine interface model. Each operator demonstrates aspects of his/her specific cognitive behavior and interacts with other operators and the environment in order to deal with an incident. Individual human factors, which determine the basis of communication and interaction between individuals, and cognitive process of an operator, such as information acquisition, state-recognition, decision-making and action execution during development of an event scenario are modeled. A case of feed and bleed operation in pressurized water reactor under an emergency situation was studied and the result was compared with an experiment to check the validity of the proposed model

In order to support development of the dynamic reliability analysis program DYANA, analyses were made on the event sequences anticipated under emergency situations using the plant dynamics simulation computer code Super-COPD. The analytical models were developed for Super-COPD such as the guard vessel, the maintenance cooling system, the sodium overflow and makeup system, etc. in order to apply the code to the simulation of the emergency situations. The input data were prepared for the analyses. About 70 sequences were analyzed, which are categorized into the following events: (1) PLOHS (Protected Loss of Heat Sink), (2) LORL (Loss of Reactor Level)-J: failure of sodium makeup by the primary sodium overflow and makeup system, (3) LORL-G : failure of primary coolant pump trip, (4) LORL-I: failure of the argon cover gas isolation, and (5) heat removal only using the ventilation system of the primary cooling system rooms. The results were integrated into an input file for preparing the functions for the neural network simulation. (author)

Sensitivity towards fear of electric shock in passive threat situations.

Directory of Open Access Journals (Sweden)

Patrick Ring

Full Text Available 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.

Directory of Open Access Journals (Sweden)

Milam, A.

2015-07-01

Full Text Available One of the most robust findings in work psychology is the role that conscientiousness plays in performance; more recently, research indicates that conscientious employees are also the most engaged in their work. The present study examines whether the organization has any role in this relation, and if it is possible for individuals who are low in conscientiousness to also feel high levels of engagement. One hundred forty-one full-time Romanian workers and their peers, representing a variety of industries, were surveyed, revealing that features of the organization can actually attenuate the relation between conscientiousness and engagement. Specifically, when employees perceive that the organization is relatively formalized (i.e., where following rules is important, and in organizations where there is a perception that effort is rewarded, conscientiousness is not as strongly associated with engagement. These organizational features represent situational strength, and when situations are strong, scripts and rules tend to predict behavior, rather than personality. As such, it may be possible for low-conscientiousness individuals to actually become more engaged through organizational change. For those who are low in conscientiousness, for example, a formal work environment likely provides structure and decreases ambiguity, which aids in lower conscientious employees becoming more engaged. Similarly, when it is perceived that the organization rewards effort, those who are low in conscientiousness receive this reinforcement, and likely benefit the most, as their levels of engagement tend to approach those who are higher in conscientiousness.

Situational Analysis of Engineering Practice

DEFF Research Database (Denmark)

Buch, Anders

STS inspired studies of engineering work practices provide new material for a richer understanding of engineering culture. However, the specific and strictly situated focus of many of these studies threatens to limit discussions of engineering practices to departmental and discrete institutional...... settings. This micro perspective potentially overlooks the inherent and overarching normativities that inform engineering culture. Furthermore, the micro perspective has difficulties in transgressing institutional boundaries in order to investigate the dynamics of cultural reproduction in engineering....... The paper will propose a research agenda that – inspired by George Marcus’ multi-sited ethnographic methodology (Marcus 1998) and Adele Clarke’s situational analysis (Clarke 2005) – analyze (and contrasts) engineering practices in diverse settings (e.g. engineering education and engineering work) in order...

The prefect facing emergency situation

Masse, H.

2006-01-01

In the field of emergency procedures regarding the protection of life, property and the environment, the 'prefet' of a department is the only public authority both representative of the state and accountable. In France laws and regulations have been in recent years revised in order to modernize emergency situations management. The 'prefet' of the Drome 'department', Henri MASSE, presents a summary of recent developments and explains how his services are organised in order to be able to handle emergency situations. He also focuses on his experience of handling the specific difficulties of nuclear risks, his department sheltering numerous nuclear facilities: EURODIF Pierrelatte nuclear fuel enrichment plant, EDF Tricastin nuclear power plant, AREVA Valence FBFC nuclear fuel manufacturing unit, etc. (author)

Adolescents' sense-making of alcohol-related risks: The role of drinking situations and social settings.

Science.gov (United States)

Katainen, Anu; Lehto, Anna-Sofia; Maunu, Antti

2015-09-01

The article explores how young people understand the risks of alcohol use and how these understandings are associated with differing drinking situations and social settings. By taking account of situational factors, the aim is to demonstrate how young people have highly nuanced notions of drinking styles that suit different drinking situations and of associated risks. The data for the research were gathered in 18 group interviews with Finnish ninth graders aged 14-15 years. Short film clips portraying young people in different drinking situations were used as stimulus material for the interviews. Data analysis focussed on the risk factors related to the social situations illustrated in the film clips. The results show that young people's risk assessments are not based on alcohol itself, but the magnitude of risk is estimated in relation to the social setting of the drinking situation. What is relevant for young people is whether the social situation allows them to make choices with which they feel comfortable. At the opposite pole of problem drinking was social drinking for the purpose of having fun together with other people in such a way that one remains in control of the drinking situation. From a prevention point of view, a key implication is that awareness of the risks is closely associated with situational and social factors. However, the awareness of those risks does not necessarily prevent young people from drinking because they may be accepted as part of the drinking experience. © The Author(s) 2014.

Johannsen, G.; Rouse, W. B.; Hillmann, K.

1981-01-01

A methodology for the study of human planning behavior in complex dynamic systems is presented and applied to the study of aircraft pilot behavior in normal, abnormal and emergency situations. The method measures the depth of planning, that is the level of detail employed with respect to a specific task, according to responses to a verbal questionnaire, and compares planning depth with variables relating to time, task criticality and the probability of increased task difficulty. In two series of experiments, depth of planning was measured on a five- or ten-point scale during various phases of flight in a HFB-320 simulator under normal flight conditions, abnormal scenarios involving temporary runway closure due to snow removal or temporary CAT-III conditions due to a dense fog, and emergency scenarios involving engine shut-down or hydraulic pressure loss. Results reveal a dichotomy between event-driven and time-driven planning, different effects of automation in abnormal and emergency scenarios and a low correlation between depth of planning and workload or flight performance.

Testing Situation Awareness Network for the Electrical Power Infrastructure

2016-09-01

Full Text Available The contemporary electrical power infrastructure is exposed to new types of threats. The cause of such threats is related to the large number of new vulnerabilities and architectural weaknesses introduced by the extensive use of Information and communication Technologies (ICT in such complex critical systems. The power grid interconnection with the Internet exposes the grid to new types of attacks, such as Advanced Persistent Threats (APT or Distributed-Denial-ofService (DDoS attacks. When addressing this situation the usual cyber security technologies are prerequisite, but not sufficient. To counter evolved and highly sophisticated threats such as the APT or DDoS, state-of-the-art technologies including Security Incident and Event Management (SIEM systems, extended Intrusion Detection/Prevention Systems (IDS/IPS and Trusted Platform Modules (TPM are required. Developing and deploying extensive ICT infrastructure that supports wide situational awareness and allows precise command and control is also necessary. In this paper the results of testing the Situational Awareness Network (SAN designed for the energy sector are presented. The purpose of the tests was to validate the selection of SAN components and check their operational capability in a complex test environment. During the tests’ execution appropriate interaction between the components was verified.

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.

Athletic Training Clinical Instructors as Situational Leaders.

Science.gov (United States)

Meyer, Linda Platt

2002-12-01

OBJECTIVE: To present Situational Leadership as a model that can be implemented by clinical instructors during clinical education. Effective leadership occurs when the leadership style is matched with the observed followers' characteristics. Effective leaders anticipate and assess change and adapt quickly and grow with the change, all while leading followers to do the same. As athletic training students' levels of readiness change, clinical instructors also need to transform their leadership styles and strategies to match the students' ever-changing observed needs in different situations. DATA SOURCES: CINAHL (1982-2002), MEDLINE (1990-2001), SPORT Discus (1949-2002), ERIC (1966-2002), and Internet Web sites were searched. Search terms included leadership, situational leadership, clinical instructors and leadership, teachers as leaders, and clinical education. DATA SYNTHESIS: Situational Leadership is presented as a leadership model to be used by clinical instructors while teaching and supervising athletic training students in the clinical setting. This model can be implemented to improve the clinical-education process. Situational leaders, eg, clinical instructors, must have the flexibility and range of skills to vary their leadership styles to match the challenges that occur while teaching athletic training students. CONCLUSIONS/RECOMMENDATIONS: This leadership style causes the leader to carry a substantial responsibility to lead while giving power away. Communication is one of the most important leadership skills to develop to become an effective leader. It is imperative for the future of the profession that certified athletic trainers continue to develop effective leadership skills to address the changing times in education and expectations of the athletic training profession.

Seeking Health Information Online: The Moderating Effects of Problematic Situations on User Intention

Directory of Open Access Journals (Sweden)

Lidan Xia

2017-03-01

Full Text Available Purpose: This study investigates how online user intention in searching health information is affected by problematic situations. Design/methodology/approach: Based on the Theory of Reasoned Action, the Technology Acceptance Model, and Sense-making theory, we propose two dimensions of problematic situations: urgency and severity of health issues being searched online. Data were collected through a questionnaire survey among 214 Wuhan University students and analyzed using hierarchical regression analysis. Findings: Perceived usefulness, perceived ease of use, and subjective norm can influence user intention to seek health information online. The urgency of problematic situations has a negative moderating effect on the relationship between perceived ease of use and user intention and the relationship between subjective norm and user intention. The severity of problematic situations has a negative moderating effect on the relationship between subjective norm and user intention. Research limitations: The respondents of the survey are limited to students in one Chinese university, so whether this study’s results can be applied to another population or not remains to be verified. In addition, only two dimensions of problematic situations are considered in this study. Practical implications: The paper puts forward the moderating effect of problematic situations and verifies it, which is the compensation for online health information-seeking behavior research. Besides, our analyses have implications for professional design of health care systems and related consumer information searches, and improve their performance. Originality/value: Previous work has reported the effects of problematic situation on user intention to seek health information online, ignoring its influence on other factors. This empirical study extends that work to identify the influence of problematic situation when seeking intention-behavior data in two dimensions, urgency and

Positively versus negatively charged moral emotion expectancies in adolescence: the role of situational context and the developing moral self.

The study analyses adolescents' positively charged versus negatively charged moral emotion expectancies. Two hundred and five students (M= 14.83 years, SD= 2.21) participated in an interview depicting various situations in which a moral norm was either regarded or transgressed. Emotion expectancies were assessed for specific emotions (pride, guilt) as well as for overall strength and valence. In addition, self-importance of moral values was measured by a questionnaire. Results revealed that positively charged emotion expectancies were more pronounced in contexts of prosocial action than in the context of moral transgressions, whereas the opposite was true for negatively charged emotions. At the same time, expectations of guilt and pride were substantially related to the self-importance of moral values. ©2010 The British Psychological Society.

The role of reference in cross-situational word learning.

Science.gov (United States)

Wang, Felix Hao; Mintz, Toben H

2018-01-01

Word learning involves massive ambiguity, since in a particular encounter with a novel word, there are an unlimited number of potential referents. One proposal for how learners surmount the problem of ambiguity is that learners use cross-situational statistics to constrain the ambiguity: When a word and its referent co-occur across multiple situations, learners will associate the word with the correct referent. Yu and Smith (2007) propose that these co-occurrence statistics are sufficient for word-to-referent mapping. Alternative accounts hold that co-occurrence statistics alone are insufficient to support learning, and that learners are further guided by knowledge that words are referential (e.g., Waxman & Gelman, 2009). However, no behavioral word learning studies we are aware of explicitly manipulate subjects' prior assumptions about the role of the words in the experiments in order to test the influence of these assumptions. In this study, we directly test whether, when faced with referential ambiguity, co-occurrence statistics are sufficient for word-to-referent mappings in adult word-learners. Across a series of cross-situational learning experiments, we varied the degree to which there was support for the notion that the words were referential. At the same time, the statistical information about the words' meanings was held constant. When we overrode support for the notion that words were referential, subjects failed to learn the word-to-referent mappings, but otherwise they succeeded. Thus, cross-situational statistics were useful only when learners had the goal of discovering mappings between words and referents. We discuss the implications of these results for theories of word learning in children's language acquisition. Copyright © 2017 Elsevier B.V. All rights reserved.

Personality and Situation Predictors of Consistent Eating Patterns.

2015-01-01

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.

Counterfactual Problem Solving and Situated Cognition

Directory of Open Access Journals (Sweden)

Glebkin V.V.,

2017-08-01

Full Text Available The paper describes and interprets data of a study on counterfactual problem solving in representatives of modern industrial culture. The study was inspired by similar experiments carried out by A.R. Luria during his expedition to Central Asia. The hypothesis of our study was that representatives of modern industrial culture would solve counterfactual puzzles at a slower rate and with higher numbers of mistakes than similar non-counterfactual tasks. The experiments we conducted supported this hypothesis as well as provided us with some insights as to how to further develop it. For instance, we found no significant differences in time lag in solving counterfactual and ‘realistic’ tasks between the subjects with mathematical and the ones with liberal arts education. As an interpretation of the obtained data, we suggest a two-stage model of counterfactual problem solving: on the first stage, where situated cognition dominates, the realistic situation is transferred into the system of symbols unrelated to this very situation; on the second stage, operations are carried out within the framework of this new system of symbols.

2017-08-01

One of the more challenging tasks in Marine Spatial Planning (MSP) is identifying critical areas for management and conservation of fish stocks. However, this objective is difficult to achieve in data-poor situations with different sources of uncertainty. In the present study we propose a combination of hierarchical Bayesian spatial models and remotely sensed estimates of environmental variables to be used as flexible and reliable statistical tools to identify and map fish species richness and abundance hot-spots. Results show higher species aggregates in areas with higher sea floor rugosity and habitat complexity, and identify clear richness hot-spots. Our findings identify sensitive habitats through essential and easy-to-use interpretation tools, such as predictive maps, which can contribute to improving management and operability of the studied data-poor situations.

Positive effect of social work-related values on work outcomes: the moderating role of age and work situation.

Science.gov (United States)

Yeung, Dannii Y; Fung, Helene H; Chan, Darius K-S

2015-03-01

This study investigated the effect of social work-related values on job performance through job satisfaction and tested whether age and work situation would moderate such associations. This study consists of two parts: Part 1 is a cross-sectional survey among 299 Chinese clerical employees aged 19-60 years and Part 2 is a 14-day experience sampling study in a subsample of Part 1 (N = 67). Part 1 revealed that age moderated the effect of social work-related values on job performance through job satisfaction, with a stronger positive effect in older workers than in younger workers. Part 2 demonstrated that the moderating effect of age shown in Part 1 also varied across work situations. In particular, holding momentary social work-related values was beneficial to the task performance of older workers, and the effect was significantly stronger when they were in social situations than in nonsocial situations, whereas the effect remained weak among younger workers regardless of work context. Moreover, the moderating effect of age could be accounted for by future time perspective. This study supports socioemotional selectivity theory that goal orientation shifts toward the emphasis of interpersonal closeness when one perceives future time as increasingly limited. © The Author 2013.

Cross-Situational Learning with Bayesian Generative Models for Multimodal Category and Word Learning in Robots

Directory of Open Access Journals (Sweden)

Akira Taniguchi

2017-12-01

Full Text Available In this paper, we propose a Bayesian generative model that can form multiple categories based on each sensory-channel and can associate words with any of the four sensory-channels (action, position, object, and color. This paper focuses on cross-situational learning using the co-occurrence between words and information of sensory-channels in complex situations rather than conventional situations of cross-situational learning. We conducted a learning scenario using a simulator and a real humanoid iCub robot. In the scenario, a human tutor provided a sentence that describes an object of visual attention and an accompanying action to the robot. The scenario was set as follows: the number of words per sensory-channel was three or four, and the number of trials for learning was 20 and 40 for the simulator and 25 and 40 for the real robot. The experimental results showed that the proposed method was able to estimate the multiple categorizations and to learn the relationships between multiple sensory-channels and words accurately. In addition, we conducted an action generation task and an action description task based on word meanings learned in the cross-situational learning scenario. The experimental results showed that the robot could successfully use the word meanings learned by using the proposed method.

The situation is compared with national average trends. The paper shows that socio-economic situation in the Far Eastern Federal District remains unstable and is characterized by the following trends: falling growth potential of industrial production with continued weak positive growth resulting from the growth in extractive industries; stagnating production in processing industries as a result of reduced investment due to restricted access to international financial resources and increased price of borrowing; continued negative dynamics of investment activity due to completion of large investment projects and slow development of new investment initiatives; continued negative dynamics of foreign trade; continuing sharp decreases of exports due to falling global oil and gas prices; reduction of imports across main import groups with the exceptin of machines and equipment; decline of real wages and household income

Decoupling, situated cognition and immersion in art.

Science.gov (United States)

Reboul, Anne

2015-09-01

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.

Full Text Available Objective: To evaluate the current community pharmacists’ interventions and job satisfaction, secondary to the alteration in the financial rewards. Methods: A cross-sectional study was carried out, using a proportionate random sample of Lebanese community pharmacy owners from all districts of Lebanon. Results: Out of 1618 distributed questionnaires, 1465 (90.5% were collected back from pharmacy owners. Our study results showed that the monthly sales and profit decreased significantly in the last decade as well as the number of loyal customers (p<0.001 for all. The rent, the total assistant pharmacists’ and employees’ salaries, income taxes, municipality fees, the total bills (electricity, water, cleaning, security and the disposal of expired products per year significantly increased during the last 10 years (p<0.001. 95% of the owners said they cannot afford to hire any more pharmacists while 45% said they cannot afford buying software for their pharmacies. Finally, 89% of these owners admitted that their situation was better 10 years ago compared to nowadays. Conclusion: Most Lebanese community pharmacists are not financially satisfied; their financial situation deteriorated in the last decade. The ministry of Health along with the Order of Pharmacists in Lebanon should cooperate together to resolve this problem since they are two entities responsible for the patient’s health.

ROPES reveals past land cover and pollen productivity estimates from single pollen records

Science.gov (United States)

Theuerkauf, Martin; Couwenberg, John

2018-04-01

Quantitative reconstructions of past vegetation cover commonly require pollen productivity estimates (PPEs). PPEs are calibrated in extensive and rather cumbersome surface-sample studies, and are so far only available for selected regions. Moreover, it may be questioned whether present-day pollen-landcover relationships are valid for palaeo-situations. We here introduce the ROPES approach that simultaneously derives PPEs and mean plant abundances from single pollen records. ROPES requires pollen counts and pollen accumulation rates (PARs, grains cm-2 year-1). Pollen counts are used to reconstruct plant abundances following the REVEALS approach. The principle of ROPES is that changes in plant abundance are linearly represented in observed PAR values. For example, if the PAR of pine doubles, so should the REVEALS reconstructed abundance of pine. Consequently, if a REVEALS reconstruction is ‘correct’ (i.e. ‘correct’ PPEs are used) the ratio ‘PAR over REVEALS’ is constant for each taxon along all samples of a record. With incorrect PPEs, the ratio will instead vary. ROPES starts from random (likely incorrect) PPEs, but then adjusts them using an optimization algorithm with the aim to minimize variation in the ‘PAR over REVEALS’ ratio across the record. ROPES thus simultaneously calculates mean plant abundances and PPEs. We illustrate the approach with test applications on nine synthetic pollen records. The results show that good performance of ROPES requires data sets with high underlying variation, many samples and low noise in the PAR data. ROPES can deliver first landcover reconstructions in regions for which PPEs are not yet available. The PPEs provided by ROPES may then allow for further REVEALS-based reconstructions. Similarly, ROPES can provide insight in pollen productivity during distinct periods of the past such as the Lateglacial. We see a potential to study spatial and temporal variation in pollen productivity for example in relation to site

Full Text Available A prospective cohort study (Copenhagen Perinatal Birth Cohort 1959-61 of 7,222 persons was used in order to explore the association between the social and health situation during pregnancy and the global quality of life (QOL of the adult child 31-33 years later. Two sets of questionnaires were used with one filled out by physicians during pregnancy and one filled out by the adult children 31-33 years later. The questionnaires included mother's situation during pregnancy and global QOL of the child at follow-up: Well-being, life satisfaction, happiness, fulfilment of needs, experience of life’s temporal and spatial domains, expression of life’s potentials and objective measures. The only indicators to have clear connections with a reduced quality of life were the cases of mother's with syphilis (8.5%, mother's congenital malformations (8.8%, low social group (6.9% and failing contraception (3.8%. The results obtained repudiate the common notion and hypothesis that the mother's situation during pregnancy is highly important for the quality of life that the child experience as an adult. This suggest that the aspects important for quality of life later on are not found solely in early conditions, but instead more dependent on later attitude towards life of that specific person.

Review of game theory applications for situation awareness

Science.gov (United States)

Blasch, Erik; Shen, Dan; Pham, Khanh D.; Chen, Genshe

2015-05-01

Game theoretical methods have been used for spectral awareness, space situational awareness (SSA), cyber situational awareness (CSA), and Intelligence, Surveillance, and Reconnaissance situation awareness (ISA). Each of these cases, awareness is supported by sensor estimation for assessment and the situation is determined from the actions of multiple players. Game theory assumes rational actors in a defined scenario; however, variations in social, cultural and behavioral factors include the dynamic nature of the context. In a dynamic data-driven application system (DDDAS), modeling must include both the measurements but also how models are used by different actors with different priorities. In this paper, we highlight the applications of game theory by reviewing the literature to determine the current state of the art and future needs. Future developments would include building towards knowledge awareness with information technology (e.g., data aggregation, access, indexing); multiscale analysis (e.g., space, time, and frequency), and software methods (e.g., architectures, cloud computing, protocols).

Individual dosimetry in planned, existing and accidental exposure situations

International Nuclear Information System (INIS)

Gomaa, M.A.M; El Deen, T.S.; Morsy, T.; Shabon, M.H.

2010-01-01

There are three types of radiation exposure which include Planned exposure situations, Existing exposure situations and Emergency exposure situations which are defined as Situations that may occur during the operation of a planned situation, or from a malicious act, or from any other unexpected situation, and require urgent action in order to avoid or reduce undesirable consequences. A given individual may be exposed as a worker, and/or as a member of the public, and/or as a patient. Workers in medical professions involving radiation are occupationally exposed. For individual monitoring of exposed workers, Film badges or thermo luminescence dosimeters are in use. In cases where individual may be suspected to be contaminated internally, contamination monitors are used to monitor the site and whole body counters to monitor individuals. Members of the public are exposure to cosmic rays during air flights. Film badges were used to exposure of workers to NORM during maintenance work in old oil field. TLD is used for exposure workers in nuclear medicine department. Any radiation accident will add knowledge and experience. Accidents from lost, stolen or neglected sources are particularly special because the radiation exposure patterns of the individuals involved and the scenario of the accident are always different

Ecological interface design for turbine secondary systems in a nuclear power plant : effects on operator situation awareness

International Nuclear Information System (INIS)

Kwok, J.

2007-01-01

Investigations into past accidents at nuclear power generating facilities such as that of Three Mile Island have identified human factors as one of the foremost critical aspects in plant safety. Errors resulting from limitations in human information processing are of particular concern for human-machine interfaces (HMI) in plant control rooms. This project examines the application of Ecological Interface Design (EID) in HMI information displays and the effects on operator situation awareness (SA) for turbine secondary systems based on the Swedish Forsmark 3 boiling-water reactor nuclear power plant. A work domain analysis was performed on the turbine secondary systems yielding part-whole decomposition and abstraction hierarchy models. Information display requirements were subsequently extracted from the models. The resulting EID information displays were implemented in a full-scope simulator and evaluated with six licensed operating crews from the Forsmark 3 plant. Three measures were used to examine SA: self-rated bias, Halden Open Probe Elicitation (HOPE), and Situation Awareness Control Room Inventory (SACRI). The data analysis revealed that operators achieved moderate to good SA; operators unfamiliar with EID information displays were able to develop and maintain comparable levels of SA to operators using traditional forms of single sensor-single indicator (SS-SI) information displays. With sufficient training and experience, operator SA is expected to benefit from the knowledge-based visual elements in the EID information displays. This project was researched in conjunction with the Cognitive Engineering Laboratory at the University of Toronto and the Institute for Energy Technology (IFE) in Halden, Norway. (author)

Prospects and requirements for an operational modelling unit in flood crisis situations

Directory of Open Access Journals (Sweden)

Anders Katharina

2016-01-01

Full Text Available Dike failure events pose severe flood crisis situations on areas in the hinterland of dikes. In recent decades the importance of being prepared for dike breaches has been increasingly recognized. However, the pre-assessment of inundation resulting from dike breaches is possible only based on scenarios, which might not reflect the situation of a real event. This paper presents a setup and workflow that allows to model dike breachinduced inundation operationally, i.e. when an event is imminent or occurring. A comprehensive system setup of an operational modelling unit has been developed and implemented in the frame of a federal project in Saxony-Anhalt, Germany. The modelling unit setup comprises a powerful methodology of flood modelling and elaborated operational guidelines for crisis situations. Nevertheless, it is of fundamental importance that the modelling unit is instated prior to flood events as a permanent system. Moreover the unit needs to be fully integrated in flood crisis management. If these crucial requirements are met, a modelling unit is capable of fundamentally supporting flood management with operational prognoses of adequate quality even in the limited timeframe of crisis situations.

Situational variations in ethnic identity across immigration generations: Implications for acculturative change and cross-cultural adaptation.

Science.gov (United States)

Noels, Kimberly A; Clément, Richard

2015-12-01

This study examined whether the acculturation of ethnic identity is first evident in more public situations with greater opportunity for intercultural interaction and eventually penetrates more intimate situations. It also investigated whether situational variations in identity are associated with cross-cultural adaptation. First-generation (G1), second-generation (G2) and mixed-parentage second-generation (G2.5) young adult Canadians (n = 137, n = 169, and n = 91, respectively) completed a questionnaire assessing their heritage and Canadian identities across four situational domains (family, friends, university and community), global heritage identity and cross-cultural adaptation. Consistent with the acculturation penetration hypothesis, the results showed Canadian identity was stronger than heritage identity in public domains, but the converse was true in the family domain; moreover, the difference between the identities in the family domain was attenuated in later generations. Situational variability indicated better adaptation for the G1 cohort, but poorer adaptation for the G2.5 cohort. For the G2 cohort, facets of global identity moderated the relation, such that those with a weaker global identity experienced greater difficulties and hassles with greater identity variability but those with a stronger identity did not. These results are interpreted in light of potential interpersonal issues implied by situational variation for each generation cohort. © 2015 International Union of Psychological Science.

2016-01-01

The present study examined whether thin-slice ratings of child personality serve as a resource-efficient and theoretically valid measurement of child personality traits. We extended theoretical work on the observability, perceptual accuracy, and situational consistency of childhood personality traits by examining intersource and interjudge agreement, cross-situational consistency, and convergent, divergent, and predictive validity of thin-slice ratings. Forty-five unacquainted independent coders rated 326 children's (ages 8-12) personality in 1 of 15 thin-slice behavioral scenarios (i.e., 3 raters per slice, for over 14,000 independent thin-slice ratings). Mothers, fathers, and children rated children's personality, psychopathology, and competence. We found robust evidence for correlations between thin-slice and mother/father ratings of child personality, within- and across-task consistency of thin-slice ratings, and convergent and divergent validity with psychopathology and competence. Surprisingly, thin-slice ratings were more consistent across situations in this child sample than previously found for adults. Taken together, these results suggest that thin slices are a valid and reliable measure to assess child personality, offering a useful method of measurement beyond questionnaires, helping to address novel questions of personality perception and consistency in childhood.

Stoeckl, L.; Banks, V.

2017-12-01

In Solotvyno, Ukraine, several salt mines were unexpectedly flooded in the recent past. As a result, dozens of sinkholes formed and are still forming with diameters up to 250 m. A one month advisory mission by the European Commission was launched in fall 2016 to conduct a risk assessment. The former mining area is situated in close vicinity to the river Theiss, which is the largest contributory of the largest river in Europe: the Danube. As river contamination by the release of large quantities of saltwater would lead to an international disaster, hydrogeological measurements were taken on-site to study the system. Saturated (hyper-saline) water as well as fresh surface and groundwater were encountered in different locations of the former mining area. Water samples were analyzed for chemistry and stable isotopes at BGR revealing insight into groundwater flow dynamics. Satellite imaging and interferometric synthetic aperture radar (SAR) were applied to study ground movements and evaluate the risk of further collapses. A resulting conceptual model explains the processes of sinkhole formation as well as the natural restoration of the salt dome prior to mining operations. This study shows the advantage of an interdisciplinary approach to conduct a risk assessment in the case of large mine collapses.

Acting without seeing: eye movements reveal visual processing without awareness.

Science.gov (United States)

Spering, Miriam; Carrasco, Marisa

2015-04-01

Visual perception and eye movements are considered to be tightly linked. Diverse fields, ranging from developmental psychology to computer science, utilize eye tracking to measure visual perception. However, this prevailing view has been challenged by recent behavioral studies. Here, we review converging evidence revealing dissociations between the contents of perceptual awareness and different types of eye movement. Such dissociations reveal situations in which eye movements are sensitive to particular visual features that fail to modulate perceptual reports. We also discuss neurophysiological, neuroimaging, and clinical studies supporting the role of subcortical pathways for visual processing without awareness. Our review links awareness to perceptual-eye movement dissociations and furthers our understanding of the brain pathways underlying vision and movement with and without awareness.

Revealing the meteorological drivers of the September 2015 severe dust event in the Eastern Mediterranean

Directory of Open Access Journals (Sweden)

P. Gasch

2017-11-01

Full Text Available In September 2015 one of the severest and most unusual dust events on record occurred in the Eastern Mediterranean. Surprisingly, operational dust transport models were unable to forecast the event. This study details the reasons for this failure and presents simulations of the event at convection-permitting resolution using the modelling system ICON-ART. The results allow for an in-depth analysis of the influence of the synoptic situation, the complex interaction of multiple driving atmospheric systems and the mineral dust radiative effect on the dust event. A comparison of the results with observations reveals the quality of the simulation results with respect to structure and timing of the dust transport. The forecast of the dust event is improved decisively. The event is triggered by the unusually early occurrence of an active Red Sea trough situation with an easterly axis over Mesopotamia. The connected sustained organized mesoscale convection produces multiple cold-pool outflows responsible for intense dust emissions. Complexity is added by the interaction with an intense heat low, the inland-penetrating Eastern Mediterranean sea breeze and the widespread occurrence of supercritical flow conditions and subsequent hydraulic jumps in the vicinity of the Dead Sea Rift Valley. The newly implemented mineral dust radiation interaction leads to systematically more intense and faster propagating cold-pool outflows.

Effects of occupational future time perspective on managing stressful work situations.

2016-08-01

According to the socioemotional selectivity theory (SST; Carstensen, 2006), older adults perceive their future time as increasingly limited, which motivates them to focus more on emotional goals and prefer passive emotion-focused strategies. This study aims to investigate the effect of occupational future time perspective (OFTP) on the use of problem-solving strategies in stressful work situations and to examine the effectiveness of these strategies on psychological well-being. A sample of 199 Chinese clerical workers responded to a structured questionnaire on problem-solving strategy use in relation to hypothetical work scenarios. Results revealed that relative to those with limited OFTP, workers with expansive OFTP preferred problem-focused and proactive strategies in both low- and high-emotionally salient scenarios. Workers with limited OFTP consistently preferred passive strategies irrespective of emotional salience. OFTP moderated the effect of problem-focused strategies on psychological distress. In particular, there was a significant negative relationship between problem-focused strategies and psychological distress among workers with expansive OFTP, but such pattern of relationship was not observed among workers with limited OFTP. Findings of this study inform the training strategies employed by practitioners to fit the developmental goals of workers in order to maximise their strengths at work. © 2015 International Union of Psychological Science.

The intensive care unit environment focuses on interventions and support therapies that prolong life. The exercise by nurses of their autonomy impacts on perception of the role they assume in the multidisciplinary team and on their function in the intensive care unit context. There is much international research relating to nurses' involvement in end-of-life situations; however, there is a paucity of research in this area in Brazil. In the Brazilian medical scenario, life support limitation generated a certain reluctance of a legal nature, which has now become unjustifiable with the publication of a resolution by the Federal Medical Council. In Brazil, the lack of medical commitments to end-of-life care is evident. To understand the process by which nurses exercise autonomy in making end-of-life decisions in intensive care units. Symbolic Interactionism and Corbin and Strauss theory methodology were used for this study. Data were collected through single audio-recorded qualitative interviews with 14 critical care nurses. The comparative analysis of the data has permitted the understanding of the meaning of nurse's experience in exercising autonomy relating to end-of-life decision-making. Institutional ethics approval was obtained for data collection. Participants gave informed consent. All data were anonymized. The results revealed that nurses experience the need to exercise autonomy in intensive care units on a daily basis. Their experience expressed by the process of increase opportunities to exercise autonomy is conditioned by the pressure of the intensive care unit environment, in which nurses can grow, feel empowered, and exercise their autonomy or else can continuously depend on the decisions made by other professionals. Nurses exercise their autonomy through care. They work to create new spaces at the same time that they acquire new knowledge and make decisions. Because of the complexity of the end-of-life situation, nurses must adopt a proactive attitude

Personality and Behavior in Social Dilemmas: Testing the Situational Strength Hypothesis and the Role of Hypothetical Versus Real Incentives.

Science.gov (United States)

Lozano, José H

2016-02-01

Previous research aimed at testing the situational strength hypothesis suffers from serious limitations regarding the conceptualization of strength. In order to overcome these limitations, the present study attempts to test the situational strength hypothesis based on the operationalization of strength as reinforcement contingencies. One dispositional factor of proven effect on cooperative behavior, social value orientation (SVO), was used as a predictor of behavior in four social dilemmas with varying degree of situational strength. The moderating role of incentive condition (hypothetical vs. real) on the relationship between SVO and behavior was also tested. One hundred undergraduates were presented with the four social dilemmas and the Social Value Orientation Scale. One-half of the sample played the social dilemmas using real incentives, whereas the other half used hypothetical incentives. Results supported the situational strength hypothesis in that no behavioral variability and no effect of SVO on behavior were found in the strongest situation. However, situational strength did not moderate the effect of SVO on behavior in situations where behavior showed variability. No moderating effect was found for incentive condition either. The implications of these results for personality theory and assessment are discussed. © 2014 Wiley Periodicals, Inc.

2014-01-01

This paper puts forward a grey situation group decision-making method on the basis of prospect theory, in view of the grey situation group decision-making problems that decisions are often made by multiple decision experts and those experts have risk preferences. The method takes the positive and negative ideal situation distance as reference points, defines positive and negative prospect value function, and introduces decision experts' risk preference into grey situation decision-making to make the final decision be more in line with decision experts' psychological behavior. Based on TOPSIS method, this paper determines the weight of each decision expert, sets up comprehensive prospect value matrix for decision experts' evaluation, and finally determines the optimal situation. At last, this paper verifies the effectiveness and feasibility of the method by means of a specific example.

Affective responses to emotional words are boosted in communicative situations.

Rohr, Lana; Abdel Rahman, Rasha

2015-04-01

Emotional verbal messages are typically encountered in meaningful contexts, for instance, during face-to-face communication in social situations. Yet, they are often investigated by confronting single participants with isolated words on a computer screen, thus potentially lacking ecological validity. In the present study we recorded event-related brain potentials (ERPs) during emotional word processing in communicative situations provided by videos of a speaker, assuming that emotion effects should be augmented by the presence of a speaker addressing the listener. Indeed, compared to non-communicative situations or isolated word processing, emotion effects were more pronounced, started earlier and lasted longer in communicative situations. Furthermore, while the brain responded most strongly to negative words when presented in isolation, a positivity bias with more pronounced emotion effects for positive words was observed in communicative situations. These findings demonstrate that communicative situations--in which verbal emotions are typically encountered--strongly enhance emotion effects, underlining the importance of social and meaningful contexts in processing emotional and verbal messages.

Methodological Consequences of Situation Specificity: Biases in Assessments

Directory of Open Access Journals (Sweden)

Jean-Luc Patry

2011-02-01

Full Text Available Social research is plagued by many biases. Most of them are due to situation specificity of social behavior and can be explained using a theory of situation specificity. The historical background of situation specificity in personality social psychology research is briefly sketched, then a theory of situation specificity is presented in detail, with as centerpiece the relationship between the behavior and its outcome which can be described as either the more, the better or not too much and not too little. This theory is applied to reliability and validity of assessments in social research. The distinction between maximum performance and typical performance is shown to correspond to the two behavior-outcome relations. For maximum performance, issues of reliability and validity are much easier to be solved, whereas typical performance is sensitive to biases, as predicted by the theory. Finally, it is suggested that biases in social research are not just systematic error, but represent relevant features to be explained just as other behavior, and that the respective theories should be integrated into a theory system.

Constraints and triggers: situational mechanics of gender in negotiation.

Science.gov (United States)

Bowles, Hannah Riley; Babcock, Linda; McGinn, Kathleen L

2005-12-01

The authors propose 2 categories of situational moderators of gender in negotiation: situational ambiguity and gender triggers. Reducing the degree of situational ambiguity constrains the influence of gender on negotiation. Gender triggers prompt divergent behavioral responses as a function of gender. Field and lab studies (1 and 2) demonstrated that decreased ambiguity in the economic structure of a negotiation (structural ambiguity) reduces gender effects on negotiation performance. Study 3 showed that representation role (negotiating for self or other) functions as a gender trigger by producing a greater effect on female than male negotiation performance. Study 4 showed that decreased structural ambiguity constrains gender effects of representation role, suggesting that situational ambiguity and gender triggers work in interaction to moderate gender effects on negotiation performance.

Handayani, D O D; Shah, A; Sediono, W

2013-01-01

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

2006-12-01

Based on the monitoring data for years in Shandong Province, current situation of acid rain in every city was assessed, and the temporal distribution of the dry, wet and total sulfur deposition in Jinan and Qingdao were studied. The results showed that Qingdao which had the largest precipitation acidity was the single city whose annul average precipitation pH was below 5. 60. The precipitation acidities in the main cities of Shandong Province were in a descent tendency. The total sulfur desposition in Jinan and Qingdao was basically stable or in a descent tendency, but also reached 10 t/(km(2)x a) or so. Among the total sulfur deposition flux, the dry deposition of sulfur had the greater contribution, and the contribution of SO2 dry deposition was higher than that of SO42- dry deposition. By analyzing the relation between the precipitation acidity and the SO2 discharge intensity, soil acidity and meteorological condition, the impact factors of acid precipitation in the cities of Shandong Province were revealed.

Critical Omissions and New Directions for Sustainable Tourism: A Situated Macro–Micro Approach

Directory of Open Access Journals (Sweden)

Blanca A. Camargo

2013-10-01

Full Text Available This paper traces the history and evolution of sustainable tourism and identifies some critical issues and omissions in this and related approaches such as responsible tourism, ecotourism and pro-poor tourism. The academic, institutional and practical intersections of sustainable tourism and responsible tourism are examined. It reveals that important theoretical and practical considerations around well-being, inclusion, and sustainability have been omitted. A critical look at ecotourism reveals additional concerns, such as a cornucopia of guidelines and principles, without clear ethical justifications to support them. At the same time, academics in this domain have been slow to consider the modernist and neoliberal influences shaping ecotourism and sustainable tourism development, such as through the discourse of ecological modernization. We identify some key omissions, such as the missing ‘body’ in sustainable tourism discourse, lack of critical analysis of postcolonial and dependency issues, and propose re-situating ‘sustainable tourism’ within a micro–macro, local-global systems approach informed by a clear framework of justice and ethics.

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

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.

Wehbe, Grasiela; Galvão, Cristina Maria; Galvão, Maria Cristina

2005-01-01

This study aimed to identify the correspondence of opinions between nurses and nursing staff members who work at the emergency unit regarding the leadership style performed by nurses and the style nurses must adopt considering the maturity level of nursing staff members and the care provided at the unit. Situational Leadership was adopted as a theoretical reference framework. In order to achieve these goals, instruments were elaborated and applied to 24 research participants. Results demonstrated that the leadership style nurses most frequently perform was E3 (participating), and that nurses should adopt leadership style E4 (delegating) in view of the nursing staff's level of maturity, suggesting that staff members present a high level of maturity (M4).

Evaluation of human fitness for duty in a real working situation

International Nuclear Information System (INIS)

Skof, M.M.

1994-01-01

According to the results of root causes analyzes in the complex highly atomized systems almost 80% of reported events and scrams are due to the human error or malfunction. Nowadays scrams are mostly consequences of human mistakes. Human mistakes are according to the results of root cause analyses consequences of unfitness or inability to perform demanded task. Most of the workers in the system have adequate psychophysiological abilities and basic knowledge. So their performance in a real working situation depends on their fitness for duty or actual availability. Actual availability and consequently human performance depends on: Human abilities (basic human traits); human knowledge (knowledge received in education process and in special training); human motivation (willingness to take part in the activity). Actual availability is the interference of abilities, knowledge and motivation in the real situation and it shapes human performance. Workers are able to self estimate their fitness for duty. On these estimations modelling of human performance in a real situation is possible. By the level of human performance system's performance should be predicted. We have developed questionnaire VTP for self estimations of well-being, mood, fatigue, arousal level, stress and motivation. At the same time data indicating human performance have been collected. Indicators of human performance have been the results on dual task and effectiveness in primary task. Connections between human fitness for duty and human performance have been modelled. Developed model explain the impacts of particular factors of fitness for duty on systems performance. (author). 5 refs, 1 tab

Franke, Stefan; Meixensberger, Jürgen; Neumuth, Thomas

2015-04-01

Surgical workflow management is expected to enable situation-aware adaptation and intelligent systems behavior in an integrated operating room (OR). The overall aim is to unburden the surgeon and OR staff from both manual maintenance and information seeking tasks. A major step toward intelligent systems behavior is a stable classification of the surgical situation from multiple perspectives based on performed low-level tasks. The present work proposes a method for the classification of surgical situations based on multi-perspective workflow modeling. A model network that interconnects different types of surgical process models is described. Various aspects of a surgical situation description were considered: low-level tasks, high-level tasks, patient status, and the use of medical devices. A study with sixty neurosurgical interventions was conducted to evaluate the performance of our approach and its robustness against incomplete workflow recognition input. A correct classification rate of over 90% was measured for high-level tasks and patient status. The device usage models for navigation and neurophysiology classified over 95% of the situations correctly, whereas the ultrasound usage was more difficult to predict. Overall, the classification rate decreased with an increasing level of input distortion. Autonomous adaptation of medical devices and intelligent systems behavior do not currently depend solely on low-level tasks. Instead, they require a more general type of understanding of the surgical condition. The integration of various surgical process models in a network provided a comprehensive representation of the interventions and allowed for the generation of extensive situation descriptions. Multi-perspective surgical workflow modeling and online situation models will be a significant pre-requisite for reliable and intelligent systems behavior. Hence, they will contribute to a cooperative OR environment. Copyright © 2015 Elsevier Inc. All rights reserved.

Validity evidence for the situational judgment test paradigm in emotional intelligence measurement.

Science.gov (United States)

Libbrecht, Nele; Lievens, Filip

2012-01-01

To date, various measurement approaches have been proposed to assess emotional intelligence (EI). Recently, two new EI tests have been developed based on the situational judgment test (SJT) paradigm: the Situational Test of Emotional Understanding (STEU) and the Situational Test of Emotion Management (STEM). Initial attempts have been made to examine the construct-related validity of these new tests; we extend these findings by placing the tests in a broad nomological network. To this end, 850 undergraduate students completed a personality inventory, a cognitive ability test, a self-report EI test, a performance-based EI measure, the STEU, and the STEM. The SJT-based EI tests were not strongly correlated with personality and fluid cognitive ability. Regarding their relation with existing EI measures, the tests did not capture the same construct as self-report EI measures, but corresponded rather to performance-based EI measures. Overall, these results lend support for the SJT paradigm for measuring EI as an ability.

The Effects of Instruction of Creative Invention on Students' Situational Interest in Physics Lesson

Science.gov (United States)

Leung, Tim

There are a few empirical studies (Palmer, 2008; Dohn, 2010) or intervention programs (Hidi & Harackiewicz, 2000) about students' situational interest in physics lessons, although the declining interest in physics among students has been well documented in the research literature (Gardner, 1998 ; International Bureau for Education, 2001; European Commission, 2007; Oon & Subramaniam, 2011). Even in the research area of science education, yet little is known about how to trigger students' catching and holding situational interest in a physics lesson. In this study, five intervention lessons of creative invention were developed. Each lesson consists of three parts including Eberle's (1971, 1972) SCAMPER technique on the creative thinking, knowledge and concepts of physics curriculum, hands-on activities related to both SCAMPER technique and physics concepts. Two surveys were developed and used to measure the situational interest and individual interest of students in physics lessons. Qualitative conversational interviews were used to interpret the sources of situational interest of students in physics lessons. Results in this study indicate that new inventive products and television programs or films related to SCAMPER can trigger the catching interest in physics lessons. Meaningful hands-on activities related to both SCAMPER technique and physics concepts can trigger the holding interest in physics lessons. There is no significant difference in situational interest among students with different academic abilities except in the topic related to electronic components. The students with lower academic ability have greater situational interest than the students with higher academic ability in learning the topic related to electronic components. There is no significant difference in situational interest between boys and girls except in the topic related to revolving paper lantern. Girls have higher situational interest than boys in learning the topic related to revolving

Context recognition and situation assessment in autonomous mobile robots

Yavnai, Arie

1993-05-01

The capability to recognize the operating context and to assess the situation in real-time is needed, if a high functionality autonomous mobile robot has to react properly and effectively to continuously changing situations and events, either external or internal, while the robot is performing its assigned tasks. A new approach and architecture for context recognition and situation assessment module (CORSA) is presented in this paper. CORSA is a multi-level information processing module which consists of adaptive decision and classification algorithms. It performs dynamic mapping from the data space to the context space, and dynamically decides on the context class. Learning mechanism is employed to update the decision variables so as to minimize the probability of misclassification. CORSA is embedded within the Mission Manager module of the intelligent autonomous hyper-controller (IAHC) of the mobile robot. The information regarding operating context, events and situation is then communicated to other modules of the IAHC where it is used to: (a) select the appropriate action strategy; (b) support the processes to arbitration and conflict resolution between reflexive behaviors and reasoning-driven behaviors; (c) predict future events and situations; and (d) determine criteria and priorities for planning, replanning, and decision making.

HUNGARIAN AND ROMANIAN COMPANIES FINANCIAL AND LIQUIDITY SITUATION IN THE LIGHT OF ECONOMIC CRISIS

Directory of Open Access Journals (Sweden)

Kinga Emese Zsido

2014-07-01

Full Text Available The behavior of the companies has changed in the last 5-6 years: they became cautious and suspicious about partners and other economic actors. This is a direct consequence of the large number of insolvent and liquidated companies, and other effects of the economic and financial crisis. The impaired financing options, the sharp fall of sales caused difficulties for companies. In general, the financial and liquidity situation of the companies is getting worse, so new financial policies are needed. To make the financial activities efficient, it is indispensable that the policy makers are aware of the real financial and liquidity situation of their own companies. But, in order to conduct successful business relationships, enterprises need to be aware of the financial situation of their partners as well. Intensified trade relations between the EU member states will require these companies to learn more about financial and liquidity situations. This present paper examines two countries, namely, a Hungarian and a Romanian region’s commercial companies financial and liquidity situations of the 2010-2012 periods. The article presents the subject both from theoretical and practical data aspects too. Based on the available e-data reports, the investigation starts with the net working capital’s examination. The working capital management has a crucial role in their financing policies. The size of the net working capital affects the degree of financial policy’s flexibility. The negative net working capital calls the attention for financial problems. The study continues with the calculation of traditional liquidity ratios, which may also reflect the liquidity situation of the companies. It is recommended not to accept the results of these indicators without calculating any other liquidity ratios. These indicators show an actual situation, so they can distort reality (positive or negative. Other indicators and methods are needed to assess the real

This study explores the experiences that women in urban poverty situation have about their participation in a psychosocial group intervention mediated by artistic techniques. An investigation was done using a qualitative methodology. Participants were ten women older than 21 years old who live in Santiago de Chile in poverty situation. Two group evaluations were performed during the intervention process and once it was completed, ten individual semi-structure interviews. The information was analyzed following the proposals of Grounded Theory, identifying negative experience about tiredness and sacrifice related to the circumstances they live in. It was possible, at the same time, to describe the benefits of an artistic activity including a psychosocial work over the individual well-being. The artistic creation was revealed as a way of expression, of re-viewing oneself and the environment, and relaxation. Transformation is discussed concerning self-affirmation, reparation and transference of this experience in their lives, as a preventive and protective resource to overcome their problems.

Some Reliability Considerations of UGV for Remote-response in Nuclear Emergency Situation

International Nuclear Information System (INIS)

Eom, Heungseop; Cho, Jaiwan; Jeong, Kyungmin

2013-01-01

In Fukushima disaster, a number of different UGVs, such as Packbots, Warriors, Quince, and Survey Runner, are used for monitoring, collecting data, inspection, and cleaning up. In utilizing UGVs in a nuclear emergency situation, one of serious problems is reliability of UGVs which is not sufficient yet for required mission completion. In this paper we surveyed failures and reliability of field UGVs and draw some important reliability considerations of UGVs for remote-response in a nuclear emergency situation. We think that the findings in this study will be helpful for developers or researchers of UGVs for nuclear emergency situations. We studied failures and reliability of UGVs used in search/rescue, military, and nuclear field by literature survey. The results showed that a state of art field UGVs can't be expected to complete an entire mission without failures, which leads to needs of reliability improvement of them. Though part of failure data from the surveyed studies were not enough detailed to get reliability matrix, some meaningful insights were found through analysis. Based on these insights, we draw some important considerations for reliability improvement of UGVs for an NPP emergency situation, and those reliability considerations are classified according to life cycle of a UGV for developers and researchers. Finally, there were not reported failures related to radiation environments in surveyed literature, but radiation tolerant control boards and sensors are easily anticipated in a NPP emergency situation. Therefore studies about the radiation-tolerant design and the use of radiation-tolerant components also should be considered for high reliability of UGVs for a NPP application

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.)

In the new millennium, understanding China’s energy economy is crucial for politicians, businesspeople and energy economists, as China’s energy policy choices will mean both challenges and opportunities for the world in terms of an increasing share of primary energy consumption and investment. This book initially reviews the literature on China’s energy economy and in so doing reveals that many important areas have been overlooked or are outdated in their coverage. Given the size of China and its global importance, the book then review s China’s current energy situation and fills the gaps in the literature for those who are interested in and concerned about China’s economic development and energy reform in the new millennium.   The book is different from previous studies in several important ways: Firstly, it presents recent,  pioneering research rather than a simple textbook, several sections of which have been published in high-quality energy journals. Secondly, the book first subdivides China'...

Examining demographic and situational factors on animal cruelty motivations.

Hensley, Christopher; Tallichet, Suzanne E; Dutkiewicz, Erik L

2011-05-01

Because of the limited number of studies that have examined the motives for childhood animal cruelty, researchers continue to suggest that further systematic study is needed. In a replication of the Hensley and Tallichet study and based on survey data from 180 inmates at one medium- and one maximum-security prison in a southern U.S. state, the present study seeks to further develop this understanding by examining the impact of demographic and situational factors on a range of animal cruelty motivations. Of the 180 inmates, 103 (57%) committed acts of animal cruelty. Logistic regression analyses revealed that respondents who committed childhood animal cruelty out of anger were less likely to cover up their behavior and to be upset by their actions but were more likely to have repeated it. Those who committed animal cruelty to shock others were more likely to reside in urban areas and to have done it alone. Furthermore, respondents who committed animal cruelty for sexual reasons were more likely to have covered up their actions and to have engaged in it repeatedly.

Harmful situations, impure people: an attribution asymmetry across moral domains.

Science.gov (United States)

Chakroff, Alek; Young, Liane

2015-03-01

People make inferences about the actions of others, assessing whether an act is best explained by person-based versus situation-based accounts. Here we examine people's explanations for norm violations in different domains: harmful acts (e.g., assault) and impure acts (e.g., incest). Across four studies, we find evidence for an attribution asymmetry: people endorse more person-based attributions for impure versus harmful acts. This attribution asymmetry is partly explained by the abnormality of impure versus harmful acts, but not by differences in the moral wrongness or the statistical frequency of these acts. Finally, this asymmetry persists even when the situational factors that lead an agent to act impurely are stipulated. These results suggest that, relative to harmful acts, impure acts are linked to person-based attributions. Copyright © 2014 Elsevier B.V. All rights reserved.

The layperson's qualification to provide early care in emergency situations and basic life support (BLS) is fundamental to save lives and prevent sequels. The objective was to identify the level of knowledge of lay people about approaching an emergency victim. Structured interviews in non-technical language were used with a 385-subject sample, average age 35.4 (+/- 14.55) years, with more than 50% having a high school or university education. Over 55% of these observed situations with loss of consciousness, but only 31% called for specialized help. 34% underwent a first-aid course, but only 13% feel prepared. The most often cited place of learning was the driving school (DS), 35.9%. Other training places were higher when compared to the DS (p = 0.048). Almost 17% do not know how to recognize the presence of vital signs. Almost 31% do not know the telephone number of the emergency service. Laypersons have incomplete or incorrect knowledge about care for unconscious victims.

The situation sequence contains a series of complicated and multivariate random trends, which are very sudden, uncertain, and difficult to recognize and describe its principle by traditional algorithms. To solve the above questions, estimating parameters of super long situation sequence is essential, but very difficult, so this paper proposes a situation prediction method based on historical feature pattern extraction (HFPE). First, HFPE algorithm seeks similar indications from the history situation sequence recorded and weighs the link intensity between occurred indication and subsequent effect. Then it calculates the probability that a certain effect reappears according to the current indication and makes a prediction after weighting. Meanwhile, HFPE method gives an evolution algorithm to derive the prediction deviation from the views of pattern and accuracy. This algorithm can continuously promote the adaptability of HFPE through gradual fine-tuning. The method preserves the rules in sequence at its best, does not need data preprocessing, and can track and adapt to the variation of situation sequence continuously.

Kim, Il-Hwa; Kim, Jeong-Woo; Haufe, Stefan; Lee, Seong-Whan

2015-02-01

Objective. We developed a simulated driving environment for studying neural correlates of emergency braking in diversified driving situations. We further investigated to what extent these neural correlates can be used to detect a participant's braking intention prior to the behavioral response. Approach. We measured electroencephalographic (EEG) and electromyographic signals during simulated driving. Fifteen participants drove a virtual vehicle and were exposed to several kinds of traffic situations in a simulator system, while EEG signals were measured. After that, we extracted characteristic features to categorize whether the driver intended to brake or not. Main results. Our system shows excellent detection performance in a broad range of possible emergency situations. In particular, we were able to distinguish three different kinds of emergency situations (sudden stop of a preceding vehicle, sudden cutting-in of a vehicle from the side and unexpected appearance of a pedestrian) from non-emergency (soft) braking situations, as well as from situations in which no braking was required, but the sensory stimulation was similar to stimulations inducing an emergency situation (e.g., the sudden stop of a vehicle on a neighboring lane). Significance. We proposed a novel feature combination comprising movement-related potentials such as the readiness potential, event-related desynchronization features besides the event-related potentials (ERP) features used in a previous study. The performance of predicting braking intention based on our proposed feature combination was superior compared to using only ERP features. Our study suggests that emergency situations are characterized by specific neural patterns of sensory perception and processing, as well as motor preparation and execution, which can be utilized by neurotechnology based braking assistance systems.

Constructing catalogue of temporal situations

Directory of Open Access Journals (Sweden)

Violetta Koseska-Toszewa

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

Alcoholism is a disease that affects parts of the brain that control emotion, decisions, and behavior. Therapy for people with alcoholism must address coping skills for facing high-risk situations. Therefore, it is important to develop tools to mimic such conditions. Cue exposure therapy (CET) provides high-risk situations during treatment, which raises the individual's ability to recognize that alcohol craving is being induced. Using CET, it is hard to simulate situations that induce alcohol craving. By contrast, virtual reality (VR) approaches can present realistic situations that cannot be experienced directly in CET. Therefore, we hypothesized that is possible to model social pressure situations using VR. We developed a VR system for inducing alcohol craving under social pressure situations and measured both the induced alcohol craving and head gaze of participants. A 2 x 2 experimental model (alcohol-related locality vs. social pressure) was designed. In situations without an avatar (no social pressure), more alcohol craving was induced if alcohol was present than if it was not. And more alcohol craving was induced in situations with an avatar (social pressure) than in situations without an avatar (no social pressure). The difference of angle between the direction of head gazing and the direction of alcohol or avatar was smaller in situations with an avatar alone (social pressure) than in situations with alcohol alone. In situations with both alcohol and an avatar, the angle between the direction of head gaze and the direction of the avatar was smaller than between the direction of head gaze and the direction of the alcohol. Considering the results, this VR system induces alcohol craving using an avatar that can express various social pressure situations.

Consumer buying decisions for food reflect considerations about food production. However, consumers’ interest in process-related product characteristics does not always translate into buying intentions. The present study investigates how situational factors affect the use of process......-related considerations when consumers select food products. A conjoint study provides estimated part worth utilities for product alternatives that differ on five product attributes (including four process-related factors) across two products (bread and sports drink) that differ on perceived naturalness....... The investigation of the utilities of the process-related attributes features both an internal (priming of environmental values/ value centrality) and an external (time pressure) situational factor. The results indicate that the importance of process-related attributes is product specific and also depends...

The nuclear industry has some specific strategic features that result in a very high level of uncertainty. The demand for new reactors has been declining for more than twenty years, and gains in performance have slowed down during the same period. As a result, at first sight, this technology should be classified as declining in terms of demand and maturing in terms of technological life cycle. This situation has important consequences on HRM inside this industry. In particular, power plant constructors have had to considerably reduce their personnel numbers. However, this industry also expects a strong revival of demand, which means that it has to preserve its key competences. This paper deals with the management of this paradoxical situation. (author)

[Quality assurance in intensive care: the situation in Switzerland].

Science.gov (United States)

Frutiger, A

1999-10-30

The movement for quality in medicine is starting to take on the dimensions of a crusade. Quite logically it has also reached the intensive care community. Due to their complex multidisciplinary functioning and because of the high costs involved, ICUs are model services reflecting the overall situation in our hospitals. The situation of Swiss intensive care is particularly interesting, because for over 25 years standards for design and staffing of Swiss ICUs have been in effect and were enforced via onsite visits by the Swiss Society of Intensive Care without government involvement. Swiss intensive care thus defined its structures long before the word "accreditation" had even been used in this context. While intensive care in Switzerland is practised in clearly defined, well equipped and adequately staffed units, much less is known about process quality and outcomes of these services. Statistics on admissions, length of stay and length of mechanical ventilation, as well as severity data based on a simple classification system, are collected nationwide and allow some limited insight into the overall process of care. Results of intensive care are not systematically assessed. In response to the constant threat of cost containment, Swiss ICUs should increasingly focus on process quality and results, while maintaining their existing good structures.

Situational motivation and perceived intensity: their interaction in predicting changes in positive affect from physical activity.

Science.gov (United States)

Guérin, Eva; Fortier, Michelle S

2012-01-01

There is evidence that affective experiences surrounding physical activity can contribute to the proper self-regulation of an active lifestyle. Motivation toward physical activity, as portrayed by self-determination theory, has been linked to positive affect, as has the intensity of physical activity, especially of a preferred nature. The purpose of this experimental study was to examine the interaction between situational motivation and intensity [i.e., ratings of perceived exertion (RPE)] in predicting changes in positive affect following an acute bout of preferred physical activity, namely, running. Fourty-one female runners engaged in a 30-minute self-paced treadmill run in a laboratory context. Situational motivation for running, pre- and post-running positive affect, and RPE were assessed via validated self-report questionnaires. Hierarchical regression analyses revealed a significant interaction effect between RPE and introjection (P positive affect was considerable, with higher RPE ratings being associated with greater increases in positive affect. The implications of the findings in light of SDT principles as well as the potential contingencies between the regulations and RPE in predicting positive affect among women are discussed.

Situational Awareness of Network System Roles (SANSR)

Huffer, Kelly M [ORNL; Reed, Joel W [ORNL

2017-01-01

In a large enterprise it is difficult for cyber security analysts to know what services and roles every machine on the network is performing (e.g., file server, domain name server, email server). Using network flow data, already collected by most enterprises, we developed a proof-of-concept tool that discovers the roles of a system using both clustering and categorization techniques. The tool's role information would allow cyber analysts to detect consequential changes in the network, initiate incident response plans, and optimize their security posture. The results of this proof-of-concept tool proved to be quite accurate on three real data sets. We will present the algorithms used in the tool, describe the results of preliminary testing, provide visualizations of the results, and discuss areas for future work. Without this kind of situational awareness, cyber analysts cannot quickly diagnose an attack or prioritize remedial actions.

Distributed sensor management for space situational awareness via a negotiation game

Science.gov (United States)

Jia, Bin; Shen, Dan; Pham, Khanh; Blasch, Erik; Chen, Genshe

2015-05-01

Space situational awareness (SSA) is critical to many space missions serving weather analysis, communications, and navigation. However, the number of sensors used in space situational awareness is limited which hinders collision avoidance prediction, debris assessment, and efficient routing. Hence, it is critical to use such sensor resources efficiently. In addition, it is desired to develop the SSA sensor management algorithm in a distributed manner. In this paper, a distributed sensor management approach using the negotiation game (NG-DSM) is proposed for the SSA. Specifically, the proposed negotiation game is played by each sensor and its neighboring sensors. The bargaining strategies are developed for each sensor based on negotiating for accurately tracking desired targets (e.g., satellite, debris, etc.) . The proposed NG-DSM method is tested in a scenario which includes eight space objects and three different sensor modalities which include a space based optical sensor, a ground radar, or a ground Electro-Optic sensor. The geometric relation between the sensor, the Sun, and the space object is also considered. The simulation results demonstrate the effectiveness of the proposed NG-DSM sensor management methods, which facilitates an application of multiple-sensor multiple-target tracking for space situational awareness.

Mobile, Collaborative Situated Knowledge Creation for Urban Planning

Directory of Open Access Journals (Sweden)

Nelson Baloian

2012-05-01

Full Text Available Geo-collaboration is an emerging research area in computer sciences studying the way spatial, geographically referenced information and communication technologies can support collaborative activities. Scenarios in which information associated to its physical location are of paramount importance are often referred as Situated Knowledge Creation scenarios. To date there are few computer systems supporting knowledge creation that explicitly incorporate physical context as part of the knowledge being managed in mobile face-to-face scenarios. This work presents a collaborative software application supporting visually-geo-referenced knowledge creation in mobile working scenarios while the users are interacting face-to-face. The system allows to manage data information associated to specific physical locations for knowledge creation processes in the field, such as urban planning, identifying specific physical locations, territorial management, etc.; using Tablet-PCs and GPS in order to geo-reference data and information. It presents a model for developing mobile applications supporting situated knowledge creation in the field, introducing the requirements for such an application and the functionalities it should have in order to fulfill them. The paper also presents the results of utility and usability evaluations.

The main purpose of this research was to study the value of radioimmunoassay (RIA) for assessing the pituitary - thyroid function in healthy persons (aged 18-45). Quantitative criteria have been worked put for estimation of thyroid gland function for the population of Belarus in accordance with regional ecological situation. On this basis, concentrations of thyrotropin, thyroxine, triiodothyronine, thyroglobulin, thyroxine binding globulin were determined by RIA in blood samples. The analysis of the data obtained revealed latent forms of hyperthyroidism (42%) and hypothyroidism (21%), regarded by the authors as late medical consequences of Chernobyl accident. Subclinical stages were diagnosed in most cases. Thus RIA has proved useful for studying the functional state of the regulatory 'pituitary-thyroid gland' system and revealing prenosological disorders in it

2015-01-01

Human–robot interactions are often affected by error situations that are caused by either the robot or the human. Therefore, robots would profit from the ability to recognize when error situations occur. We investigated the verbal and non-verbal social signals that humans show when error situations occur in human–robot interaction experiments. For that, we analyzed 201 videos of five human–robot interaction user studies with varying tasks from four independent projects. The analysis shows that there are two types of error situations: social norm violations and technical failures. Social norm violations are situations in which the robot does not adhere to the underlying social script of the interaction. Technical failures are caused by technical shortcomings of the robot. The results of the video analysis show that the study participants use many head movements and very few gestures, but they often smile, when in an error situation with the robot. Another result is that the participants sometimes stop moving at the beginning of error situations. We also found that the participants talked more in the case of social norm violations and less during technical failures. Finally, the participants use fewer non-verbal social signals (for example smiling, nodding, and head shaking), when they are interacting with the robot alone and no experimenter or other human is present. The results suggest that participants do not see the robot as a social interaction partner with comparable communication skills. Our findings have implications for builders and evaluators of human–robot interaction systems. The builders need to consider including modules for recognition and classification of head movements to the robot input channels. The evaluators need to make sure that the presence of an experimenter does not skew the results of their user studies. PMID:26217266

Highlights: ► A method for measuring team situation awareness is developed. ► Verbal protocol analysis is adopted in this method. ► This method resolves uncertainties from conventional methods. ► This method can be used in evaluating the human–system interfaces. - Abstract: Situation awareness (SA) continues to receive a considerable amount of attention from the ergonomics community given that need for operators to maintain SA is frequently cited as a key to effective and efficient performance. Although complex and dynamic environments such as that of a main control room (MCR) in a nuclear power plant (NPP) are operated by operation teams, and while team situation awareness (TSA) is also cited as an important factor, research is limited to individual SA. However, understanding TSA can provide a window onto the characteristics of team acquisition as well as the performance of a complex skill. Therefore, such knowledge can be valuable in diagnosing team performance successes and failures. Moreover, training and design interventions can target the cognitive underpinnings of team performance, with implications for the design of technological aids to improve team performance. Despite these advantages and the importance of understanding TSA, measures and methods targeting TSA are sparse and fail to address it properly. In this study, an objective TSA measurement method is developed in an effort to understand TSA. First, key considerations for developing a method are derived. Based on these considerations, the proposed method is developed while mainly focusing on the creation of logical connections between team communications and TSA. A speech act coding scheme is also implemented to analyze team communications. The TSA measurement method developed in this study provides a measure for each level of TSA. It was revealed from a preliminary study that this TSA measurement method is feasible for measuring TSA to a fair extent. Useful insight into TSA is also derived.

Hypothetical conflict situations with friends and peers

Directory of Open Access Journals (Sweden)

Petrović Danijela S.

2012-01-01

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.

Typical synoptic situations and their impacts on the wintertime air pollution in the Guanzhong basin, China

Directory of Open Access Journals (Sweden)

N. Bei

2016-06-01

Full Text Available Rapid industrialization and urbanization have caused severe air pollution in the Guanzhong basin, northwestern China, with heavy haze events occurring frequently in recent winters. Using the NCEP reanalysis data, the large-scale synoptic situations influencing the Guanzhong basin during wintertime of 2013 are categorized into six types to evaluate the contribution of synoptic situations to the air pollution, including “north-low”, “southwest-trough”, “southeast-high”, “transition”, “southeast-trough”, and “inland-high”. The FLEXPART model has been utilized to demonstrate the corresponding pollutant transport patterns for the typical synoptic situations in the basin. Except for “southwest-trough” and “southeast-high” (defined as favorable synoptic situations, the other four synoptic conditions (defined as unfavorable synoptic situations generally facilitate the accumulation of air pollutants, causing heavy air pollution in the basin. In association with the measurement of PM2.5 (particulate matter with aerodynamic diameter less than 2.5 µm in the basin, the unfavorable synoptic situations correspond to high PM2.5 mass concentrations or poor air quality and vice versa. The same analysis has also been applied to winters of 2008–2012, which shows that the basin was mainly influenced by the unfavorable synoptic situations during wintertime leading to poor air quality. The WRF-CHEM model has further been applied to simulate the selected 6 days representing the typical synoptic situations during the wintertime of 2013, and the results generally show a good agreement between the modeled distributions and variations of PM2.5 and the corresponding synoptic situations, demonstrating reasonable classification for the synoptic situations in the basin. Detailed meteorological conditions, such as temperature inversion, low-level horizontal wind speed, and planetary boundary layer, all contribute to heavy air pollution

Problems of Assessment of Influence of the Market Situation upon Competitive Position of an Enterprise in the Process of Managing its Products Competitiveness

Directory of Open Access Journals (Sweden)

Fartushnyak Olga Victorovna

2013-11-01

Full Text Available The article justifies a possibility of use of natural-science approaches when assessing the market situation in the process of forecasting competitive position of an enterprise. In order to develop further the methods of forecasting competitive position of the producer, the article offers to use approaches of the turbulent theory of motion of continuum, in particular, the Kolmogorov law of dissipation of energy of continuum when forecasting market situation values. The practical benefit of the proposed methodical approach to forecasting lies in the fact that it gives a possibility of proposing scientifically justified solutions with respect to selection of different strategies to enterprise management. Its main purpose is to clarify the way of development of a decision on the basis of revealed basic competitive positions of an enterprise, basic tendencies, main critical zones, risks of uneven changes, most difficult problems and identification of the forecast position of an enterprise with consideration of the market situation forecast.

Situations of car-to-pedestrian contact.

To reduce the severity of injuries and the number of pedestrian deaths in traffic accidents, active safety devices providing pedestrian detection are considered effective countermeasures. The features of car-to-pedestrian collisions need to be known in detail to develop such safety devices. Because information on real-world accidents is limited, this study investigated near-miss situations captured by drive recorders installed in passenger cars. We showed similarities of the contact situation between near-miss incidents and real-world fatal pedestrian accidents in Japan. We analyzed the near-miss incident data via video capturing pedestrians crossing the road in front of forward-moving cars. Using a video frame captured by a drive recorder, the time to collision (TTC) was calculated from the car velocity and the distance between the car and pedestrian at the moment that the pedestrian initially appeared. The average TTC in the cases where pedestrians were not using a pedestrian crossing was shorter than that in the cases where pedestrians were using a pedestrian crossing. The average TTC in the cases where pedestrians emerged from behind obstructions was shorter than that in the cases where drivers had unobstructed views of the pedestrians. We propose that the specifications of the safety device for pedestrian detection and automatic braking should reflect the severe approach situation for a pedestrian and car including the TTC observed for near-miss incidents.

2003-09-01

The success of any potential application for mobile robots depends largely on the specific environment where the application takes place. Practical applications are rarely found in highly structured environments, but unstructured environments (such as natural terrain) pose major challenges to any mobile robot. We believe that semi-structured environments-such as parking lots-provide a good opportunity for successful mobile robot applications. Parking lots tend to be flat and smooth, and cars can be uniquely identified by their license plates. Our scenario is a parking lot where only known vehicles are supposed to park. The robot looks for vehicles that do not belong in the parking lot. It checks both license plates and vehicle types, in case the plate is stolen from an approved vehicle. It operates autonomously, but reports back to a guard who verifies its performance. Our interest is in developing the robot's vision system, which we call Scene Estimation & Situational Awareness Mapping Engine (SESAME). In this paper, we present initial results from the development of two SESAME subsystems, the ego-location and license plate detection systems. While their ultimate goals are obviously quite different, our design demonstrates that by sharing intermediate results, both tasks can be significantly simplified. The inspiration for this design approach comes from the basic tenets of Situational Awareness (SA), where the benefits of holistic perception are clearly demonstrated over the more typical designs that attempt to solve each sensing/perception problem in isolation.

To determine the impact of nutritional status in a multicausal approach of socio-economic, socio-cultural, family, intellectual, educational and demographic variables at the onset of elementary school in 1987 on the educational situation of these children in 1998, when they should have graduated from high school. Chile's Metropolitan Region. Prospective, observational and 12-year follow-up study. A representative sample of 813 elementary first grade school-age children was randomly chosen in 1987. The sample was assessed in two cross-sectional studies. The first cross-sectional study was carried out in at the onset of elementary school in 1987 and the second was carried out in 1998, 12-years later, when they should be graduating from high school. In 1998, 632 adolescent students were located and their educational situation was registered (dropout, delayed, graduated and not located). At the onset of elementary school were determined the nutritional status, socio-economic status (SES), family characteristics, intellectual ability (IA), scholastic achievement (SA) and demographic variables. Statistical analysis included variance tests and Scheffe's test was used for comparison of means. Pearson correlation coefficients and logistic regression were used to establish the most important independent variables at the onset of elementary school in 1987 that affect the educational situation 1998. Data were analysed using the statistical analysis system (SAS). Logistic regression revealed that SES, IA, SA and head circumference-for-age Z score at the onset of elementary school in 1987 were the independent variables with the greatest explanatory power in the educational situation of school-age children in 1998. These parameters at an early school age are good predictors of the educational situation later and these results can be useful for nutrition and educational planning in early childhood.

Gender-related aspects of transmasculine people's vocal situations: insights from a qualitative content analysis of interview transcripts.

Azul, David

2016-11-01

Transmasculine people assigned female gender at birth but who do not identify with this classification have traditionally received little consideration in the voice literature. Existing analyses tend to be focused on evaluating speaker voice characteristics, whereas other factors that contribute to the production of vocal gender have remained underexplored. Most studies rely on researcher-centred perspectives, whereas very little is known about how transmasculine people themselves experience and make sense of their vocal situations. To explore how participants described their subjective gender positionings; which gender attributions they wished to receive from others; which gender they self-attributed to their voices; which gender attributions they had received from others; and how far participants were satisfied with the gender-related aspects of their vocal situations. Transcripts of semi-structured interviews with 14 German-speaking transmasculine people served as the original data corpus. Sections in which participants described the gender-related aspects of their vocal situations and that were relevant to the current research objectives were selected and explored using qualitative content analysis. The analysis revealed diverse accounts pertaining to the factors that contribute to the production of vocal gender for individual participants and variable levels of satisfaction with vocal gender presentation and attribution. Transmasculine people need to be regarded as a heterogeneous population and clinical practice needs to follow a client-centred, individualized approach. © 2016 Royal College of Speech and Language Therapists.

Being similar while judging right and wrong: The effects of personal and situational similarity on moral judgements.

Science.gov (United States)

Pascal, Emilia

2017-07-20

This study investigated the effects of similarity with the transgressor and the victim on the perceived immorality of the transgression. Participants read two stories describing a person that cheated on their partner and a police officer that mistreated somebody. In the first story we manipulated participants' personal similarity to the transgressor and in the second their personal similarity to the victim. In each story, participants' past situational similarity to the target character was assessed according to their previous experiences of being in the same position. Results show that both personal and past situational similarity to the transgressor determine less severe moral judgements, while personal and past situational similarity with the victim have the opposite effect. We also tested several potential mediators of these effects, derived from competing theoretical accounts of the influence of similarity on perceived responsibility. Empathy emerged as mediating most of the effects of similarity on moral judgements, except those induced by past situational similarity with the victim. The foreseen probability of being in a similar situation mediated only the effects of similarity to the transgressor, and not those of similarity to the victim. Overall, results highlight the complex mechanisms of the influences of similarity on moral judgements. © 2017 International Union of Psychological Science.

Cross-situational statistical word learning in young children.

Suanda, Sumarga H; Mugwanya, Nassali; Namy, Laura L

2014-10-01

Recent empirical work has highlighted the potential role of cross-situational statistical word learning in children's early vocabulary development. In the current study, we tested 5- to 7-year-old children's cross-situational learning by presenting children with a series of ambiguous naming events containing multiple words and multiple referents. Children rapidly learned word-to-object mappings by attending to the co-occurrence regularities across these ambiguous naming events. The current study begins to address the mechanisms underlying children's learning by demonstrating that the diversity of learning contexts affects performance. The implications of the current findings for the role of cross-situational word learning at different points in development are discussed along with the methodological implications of employing school-aged children to test hypotheses regarding the mechanisms supporting early word learning.

Balconi, Michela; Canavesio, Ylenia

2013-03-01

The present research firstly investigated the neural correlates (ERPs, event-related potentials) of attitudes to engage in prosocial-helping behaviors, and secondly, it analyzed the relation between these brain-based potentials and personal profile (high vs. low empathic profile). It was considered the subjects' behavior in response to specific emotional situations (positive vs. negative) in case it was required a possible prosocial intervention. Thirty-one subjects were invited to empathize with the emotional contexts (videotapes that reproduced two person's exchanges) and to decide whether to intervene or not to support these persons. BEES questionnaire for empathic behavior was submitted to the subjects after the experimental session. ERP acquisition and LORETA source analysis revealed a negative ongoing deflection (N200 effect) more prefrontally distributed (dorsolateral prefrontal cortex) in response to prosocial intervention options mainly for negative and positive contexts. Moreover, a significant positive correlation was found between high-empathic profiles, intervention behaviors (higher frequency of interventions) and N200 amplitude (higher peak). These results highlight the role of emotions in prosocial behavior, since the N200 effect was considered a marker of the emotional significance of the interpersonal situation. Secondly, the empathic trait may explain the prosocial decisional processes: Higher empathic trait contributes to induce subject's intervention behavior which in turn appears to be directly related to the cortical responsiveness within the prefrontal areas.

The power situation in Mid-Norway

International Nuclear Information System (INIS)

2006-01-01

The strained power situation in Mid-Norway is in broad terms an energy problem, and the situation is especially precarious in the county of Moere og Romsdal. There is a risk that even in normal years, there will be insufficient energy supply unless new measures are implemented. There is a 50 percent chance that the situation will become more strained than in normal years. In the long term there is a possibility to increase the capacity of the system by increasing the import capacity as well as the production, but this is not realistic before 2011. A gas work at Tjeldbergodden can at the earliest be operative in 2011. The gas work at Skogn can at the earliest be operative in 2009, and needs to be accompanied by fortifications in the distribution net in order to help the situation in Moere og Romsdal. In short term the import capacity to the region will be reduced, and there are limits to how much new production capacity that can be taken in. Therefore, measures have to be made in order to reduce the consumption and increase the import. To make sure the measures will have satisfactory effect, they need to be implemented soon, so they can have effect over a longer period. It is limited how big reduction one can expect from the normal supply consumption. It is estimated that the consumption can be reduced by 10 percent at the maximum, by the use of high prices in the area, but this requires that the consumers expect a prolonged level of high energy prices at 0,80 Nok/kWh, and in addition short-term price fluctuations. Energy-intensive industry may find it profitable to reduce the consumption at prices below 0,80 Nok/kWh, but the potential for this is probably small in Moere og Romsdal. In a dry year it will hardly be possible to meet the energy demand without resorting to measures and in worst case rationing. The costs of rationing are substantially higher than the cost of backup power plants

Agent Based Modeling and Simulation of Pedestrian Crowds In Panic Situations

KAUST Repository

Alrashed, Mohammed

2016-11-01

The increasing occurrence of panic stampedes during mass events has motivated studying the impact of panic on crowd dynamics and the simulation of pedestrian flows in panic situations. The lack of understanding of panic stampedes still causes hundreds of fatalities each year, not to mention the scarce methodical studies of panic behavior capable of envisaging such crowd dynamics. Under those circumstances, there are thousands of fatalities and twice that many of injuries every year caused be crowd stampede worldwide, despite the tremendous efforts of crowd control and massive numbers of safekeeping forces. Pedestrian crowd dynamics are generally predictable in high-density crowds where pedestrians cannot move freely and thus gives rise to self-propelling interactions between pedestrians. Although every pedestrian has personal preferences, the motion dynamics can be modeled as a social force in such crowds. These forces are representations of internal preferences and objectives to perform certain actions or movements. The corresponding forces can be controlled for each individual to represent a different variety of behaviors that can be associated with panic situations such as escaping danger, clustering, and pushing. In this thesis, we use an agent-based model of pedestrian behavior in panic situations to predict the collective human behavior in such crowd dynamics. The proposed simulations suggests a practical way to alleviate fatalities and minimize the evacuation time in panic situations. Moreover, we introduce contagious panic and pushing behavior, resulting in a more realistic crowd dynamics model. The proposed methodology describes the intensity and spread of panic for each individual as a function of distances between pedestrians.

2016-10-01

Full Text Available The following paper analyses the situation of the Csángó dialect spoken in the Romanian region of Moldavia. After a review of the global phenomenon of language death, its causes, and some resources to evaluate language vitality, the study focuses on the Csángó community and its Hungarian dialect. A short description of some fundamental facts about the group, such as ethnicity, religious affiliation, and linguistic background sets the base for an in-depth study of the language situation. In order to achieve that goal, the language was scrutinized according to the nine factors proposed by the UNESCO’s Language Vitality and Endangerment (LVE framework. The results confirm previous research in the field and show that Csángó is experiencing a decisive and most difficult phase in its history. It is expected, however, that this paper can contribute to create a successful planning to preserve not only Csángó but many other languages and dialects in similar situations.

To assess the association of socioeconomic position (SEP), measured by family financial situation and housing tenure in childhood and adulthood, with mental health conditions in adulthood. Representative cross-sectional population data were collected using a risk factor surveillance system in South Australia, Australia. Each month, a random sample were selected from the Electronic White Pages. Participants aged 25 years and above (n = 10429) were asked about doctor diagnosed anxiety, stress or depression, suicidal ideation, psychological distress, demographic and socioeconomic factors using Computer Assisted Telephone Interviewing (CATI). Social mobility measures were derived from housing status and perceived financial situation during adulthood and at 10 years of age. The prevalence of psychological distress was 8.1 %, current diagnosed mental health condition was 14.8 % and suicidal ideation was 4.3 %. Upward mobility in family financial situation and housing tenure was experienced by 28.6 % and 19.3 %, of respondents respectively. Downward mobility was experienced by 9.4 % for housing tenure and 11.3 % for family financial situation. In the multivariable analysis, after adjusting for age, sex, childhood family structure and adult education, downward social mobility and stable low SEP (both childhood and adulthood), in terms of both housing tenure and financial situation, were positively associated with all three mental health conditions. People with low SEP in adulthood had poor mental health outcomes regardless of their socioeconomic circumstances in childhood. Policies to improve SEP have the potential to reduce mental health conditions in the population.

We introduce a new nonverbal and unobtrusive measure to assess power motive activation, the Spatial Power Motivation Scale (SPMS). The unique features of this instrument are that it is (a) very simple and economical, (b) reliable and valid, and (c) sensitive to situational changes. Study 1 demonstrates the instrument's convergent and discriminant validity with explicit measures. Study 2 demonstrates the instrument's responsiveness to situational power motive salience: anticipating and winning competition versus losing competition and watching television. Studies 3 and 4 demonstrate that thoughts of competition result in higher power motivation specifically for individuals with a high dispositional power motive.

Full Text Available This study aimed to investigate the adverse personal, family, peer and school situations encountered by adolescent students who had returned to school after being suspended. This was a large-scale study involving a representative population of Taiwanese adolescents. A total of 8,494 adolescent students in Southern Taiwan were recruited in the study and completed the questionnaires. The relationships between their experiences of suspension from school and adverse personal, family, peer, and school situations were examined. The results indicated that 178 (2.1% participants had been suspended from school at some time. Compared with students who had never been suspended, those who had experienced suspension were more likely to report depression, low self-esteem, insomnia, alcohol consumption, illicit drug use, low family support, low family monitoring, high family conflict, habitual alcohol consumption, illicit drug use by family members, low rank and decreased satisfaction in their peer group, having peers with substance use and deviant behaviors, low connectedness to school, and poor academic achievement. These results indicate that adolescent students who have returned to school after suspension encounter numerous adverse situations. The psychological conditions and social contexts of these individuals need to be understood in depth, and intervention programs should be developed to help them to adjust when they return to school and to prevent school dropouts in the future.

In order to provide more consistent sound intelligibility for the hearing-impaired person, regardless of environment, it is necessary to adjust the setting of the hearing-support (HS) device to accommodate various environmental circumstances. In this study, a fully automatic HS device management algorithm that can adapt to various environmental situations is proposed; it is composed of a listening-situation classifier, a noise-type classifier, an adaptive noise-reduction algorithm, and a management algorithm that can selectively turn on/off one or more of the three basic algorithms-beamforming, noise-reduction, and feedback cancellation-and can also adjust internal gains and parameters of the wide-dynamic-range compression (WDRC) and noise-reduction (NR) algorithms in accordance with variations in environmental situations. Experimental results demonstrated that the implemented algorithms can classify both listening situation and ambient noise type situations with high accuracies (92.8-96.4% and 90.9-99.4%, respectively), and the gains and parameters of the WDRC and NR algorithms were successfully adjusted according to variations in environmental situation. The average values of signal-to-noise ratio (SNR), frequency-weighted segmental SNR, Perceptual Evaluation of Speech Quality, and mean opinion test scores of 10 normal-hearing volunteers of the adaptive multiband spectral subtraction (MBSS) algorithm were improved by 1.74 dB, 2.11 dB, 0.49, and 0.68, respectively, compared to the conventional fixed-parameter MBSS algorithm. These results indicate that the proposed environment-adaptive management algorithm can be applied to HS devices to improve sound intelligibility for hearing-impaired individuals in various acoustic environments.

The market for new power plants is presently being dominated by dramatic price rises and fully booked manufacturing capacities over the next few years. This situation also causes severe problems in the procurement of maintenance services and spares. In many cases the suppliers of new power plants and maintenance services are identical and access the same human and production resources. The paper provides an insight into the measures taken by RWE Power to assure a reliable procurement of services. (orig.)

Situation awareness and documentation of changes that affect patient outcomes in progress notes.

To report on registered nurses' situation awareness as a precursor to decision-making when recording changes in patients' conditions. Progress notes are important to communicate patients' progress and detail changes in patients' conditions. However, documentation is often poorly completed. There is little work that examines nurses' decision-making during documentation. This study focused on describing situation awareness as a precursor to decision-making during documentation. This study used Endsley's (Situation Awareness Analysis and Measurement, 2000, Lawrence Erlbaum Associates, NJ) work on situation awareness to guide and conceptualise information. The study was situated in a naturalistic paradigm to provide an interpretation of nurses' decision-making. Think-aloud research methods and semi-structured interviews were employed to illuminate decision-making processes. Audio recordings and interview texts were individually examined for evidence of cues, informed by Endsley's (Situation Awareness Analysis and Measurement, 2000, Lawrence Erlbaum Associates, NJ) descriptions of situation awareness. As patients' conditions changed, nurses used complex mental models and pattern-matching of information, drawing on all 3 levels of situation awareness during documentation. Level 1 situation awareness provided context, level 2 situation awareness signified a change in condition and its significance for the patient, and level 3 situation awareness was evident when nurses thought aloud about what this information indicated. Three themes associated with changes in patients' conditions emerged: deterioration in condition, not responding to prescribed treatments as expected and issues related to professional practice that impacted on patients' conditions. Nurses used a complex mental model for decision-making, drawing on 3 levels of situation awareness. Hamm's cognitive continuum theory, when related to situation awareness, is a useful decision-making theory to provide a

Full Text Available In this paper, a multi-period model for blood supply chain in emergency situation is presented to optimize decisions related to locate blood facilities and distribute blood products after natural disasters. In disastrous situations, uncertainty is an inseparable part of humanitarian logistics and blood supply chain as well. This paper proposes a robust network to capture the uncertain nature of blood supply chain during and after disasters. This study considers donor points, blood facilities, processing and testing labs, and hospitals as the components of blood supply chain. In addition, this paper makes location and allocation decisions for multiple post disaster periods through real data. The study compares the performances of “p-robust optimization” approach and “robust optimization” approach and the results are discussed.

Prosthetic graft infection after vascular reconstruction is a rare but serious complication. We report a case of infection occurring late after implantation of an iliofemoral prosthetic vascular graft. The Staphylococcus aureus infection was revealed by vascular purpura localized on the right leg 7 years after implantation of a vascular prosthesis. This case illustrates an uncommonly late clinical manifestation presenting as an acute infection 7 years after the primary operation. In this situation, the presentation differs from early infection, which generally occurs within the first four postoperative months. Diagnosis and treatment remain a difficult challenge because prosthetic graft infection is a potentially life-threatening complication. Morbidity and mortality rates are high. Here we detail specific aspects of the clinical and radiological presentation. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

Safety Domain Measurement for Vessels in an Overtaking Situation

Full Text Available Marine traffic engineering has been pushed to the limits due to a rising demand in the shipping business. Merchant ships are growing dramatically, both in numbers and in size. To keep pace with current developments, automation seems to be one viable option when it comes to keeping ships running with fewer seafarers available. The aim of this paper is to monitor a modern day mariners’ performance while working in a tense situation. The objective is to define the size of the safety domain whilst overtaking a vessel. The approach was to assess the ship's domain area within a 3 nm wide traffic separation scheme by using a ship handling simulator. From the simulation results, an overtaking domain was determined as 1.36 nm long and 0.4 nm wide. Safety domains in real-life situations were experienced on a much smaller scale compared to the previous findings. The working load for this particular operation is expected to be stressful and highly skilled orientated.

Situated Dialogue and Spatial Organization: What, Where… and Why?

Directory of Open Access Journals (Sweden)

Geert-Jan M. Kruijff

2007-03-01

Full Text Available The paper presents an HRI architecture for human-augmented mapping, which has been implemented and tested on an autonomous mobile robotic platform. Through interaction with a human, the robot can augment its autonomously acquired metric map with qualitative information about locations and objects in the environment. The system implements various interaction strategies observed in independently performed Wizard-of-Oz studies. The paper discusses an ontology-based approach to multi-layered conceptual spatial mapping that provides a common ground for human-robot dialogue. This is achieved by combining acquired knowledge with innate conceptual commonsense knowledge in order to infer new knowledge. The architecture bridges the gap between the rich semantic representations of the meaning expressed by verbal utterances on the one hand and the robot's internal sensor-based world representation on the other. It is thus possible to establish references to spatial areas in a situated dialogue between a human and a robot about their environment. The resulting conceptual descriptions represent qualitative knowledge about locations in the environment that can serve as a basis for achieving a notion of situational awareness.

Research was conducted at the OECD Halden Reactor Project to identify issues in crew performance in complex simulated nuclear power plant scenarios. Eight crews of operators participated in five scenarios, administered over a two or three-day period. Scenarios required either rule-based or knowledge-based problem solving. Several performance parameters were collected, including Situation Awareness (SA), objective performance, rated crew performance, and crew diagnoses. The purpose of this study was to investigate differences in performance measures in knowledge-based and rule-based scenarios. Preliminary data analysis revealed a significant difference in crew SA between the two scenario types: crews in the rule-based scenarios had significantly higher SA then crews in the knowledge-based scenarios. Further investigations were initiated to determine if crews performed differently, in terms of objective performance, rated crew performance, and diagnoses, between the scenario types. Correlations between the various crew performance measurements were calculated to reveal insights into the nature of SA, performance, and diagnoses. The insights into crew performance can be used to design more effective interfaces and operator performance aids, thus contributing to enhanced crew performance and improved plant safety. (authors)

To analyze the access and accessibility to the healthcare network of women dwelling in rural contexts undergoing violence situation, as seen from the professionals' speeches. A qualitative, exploratory, descriptive study with professionals from the healthcare network services about coping with violence in four municipalities in the northern region of Rio Grande do Sul. The information derived from interviews, which have been analyzed by thematic modality. (Lack of) information of women, distance, restricted access to transportation, dependence on the partner and (lack of) attention by professionals to welcome women undergoing violence situation and (non)-articulation of the network are factors that limit the access and, as a consequence, they result in the lack of confrontation of this problem. To bring closer the services which integrate the confrontation network of violence against women and to qualify professionals to welcome these situations are factors that can facilitate the access and adhesion of rural women to the services.

Because of the complexity of clinical situations, traditional didactic education is limited in providing opportunity for student-patient interaction. Situated e-learning can enhance learners' knowledge and associated abilities through a variety of activities. Healthcare providers who interact with virtual patients in designed situations may avoid unnecessary risks and encounters with real patients. However, the effectiveness of situated e-learning is inconsistent. The purpose of this study is to determine the effectiveness of situated e-learning in prelicensure and postlicensure medical and nursing education. Literature databases of PubMed, Medline, CINAHL, ERIC, and Cochrane Library were searched. The study eligibility criteria included articles published in English, which examined the effectiveness of situated e-learning on the outcomes of knowledge and performance for clinicians or students in medicine and nursing. Effect sizes were calculated with 95% confidence intervals. Fourteen articles were included for meta-analysis. Situated e-learning could effectively enhance learners' knowledge and performance when the control group received no training. Compared to traditional learning, the effectiveness of situated e-learning on performance diminished but still remained significant whereas the effect become insignificant on knowledge. The subgroup analyses indicate the situated e-learning program significantly improved students' clinical performance but not for clinicians. Situated e-learning is an effective method to improve novice learners' performance. The effect of situated e-learning on the improvement of cognitive ability is limited when compared to traditional learning. Situated e-learning is a useful adjunct to traditional learning for medical and nursing students. © 2013 Sigma Theta Tau International.

A study on the operator's communication pattern characteristics under abnormal operating situation of nuclear power plants

The quality of a probabilistic safety assessment (PSA) has become more important and a human reliability analysis (HRA) is known as a major contributor to the uncertainty of a PSA. As a part of enhancing the HRA quality, a study was initiated to find out characteristics of communication pattern and to evaluate communication quality of the operators of nuclear power plants. Korea Atomic Energy Research Institute (KAERI) is developing evaluation methods for the effect of human-induced events on risk/performance. This paper describes a study on the operator's communication pattern characteristics under abnormal operating situation of nuclear power plants. The study was carried out in four stages; 1) Video recording 2) Audio scripting 3) Message Classification 4) Communication Pattern Analysis. We recorded eight abnormal simulator training programs from Younggwang nuclear power plant training center. After that we performed message classification and carried out communication pattern analysis. We compared communication patterns of abnormal operating situation with emergency operating situation.As results of analysis, the role of SRO (senior reactor operator) under abnormal operating situation was decreased than the activities under emergency operating situation because each operator (reactor operator, turbine operator, safety supervisor) in main control room (MCR) performs the activity to control by himself with corresponding field engineers with his basic knowledge of the system. On the other hand, the operator's decision making processes and activities under abnormal operating situation were dramatically increased than the emergency operating situation. (authors)

Against Strong Ethical Parity: Situated Cognition Theses and Transcranial Brain Stimulation.

Heinrichs, Jan-Hendrik

2017-01-01

According to a prominent suggestion in the ethics of transcranial neurostimulation the effects of such devices can be treated as ethically on par with established, pre-neurotechnological alterations of the mind. This parity allegedly is supported by situated cognition theories showing how external devices can be part of a cognitive system. This article will evaluate this suggestion. It will reject the claim, that situated cognition theories support ethical parity. It will however point out another reason, why external carriers or modifications of the mental might come to be considered ethically on par with internal carriers. Section "Why Could There Be Ethical Parity between Neural Tissue and External Tools?" presents the ethical parity theses between external and internal carriers of the mind as well as neurotechnological alterations and established alterations. Section "Extended, Embodied, Embedded: Situated Cognition as a Relational Thesis" will elaborate the different situated cognition approaches and their relevance for ethics. It will evaluate, whether transcranial stimulation technologies are plausible candidates for situated cognition theses. Section "On the Ethical Relevance of Situated Cognition Theses" will discuss criteria for evaluating whether a cognitive tool is deeply embedded with a cognitive system and apply these criteria to transcranial brain stimulation technologies. Finally it will discuss the role diverse versions of situated cognition theory can play in the ethics of altering mental states, especially the ethics of transcranial brain stimulation technologies.

Describe the risk behaviour relationships with road safety in adolescents. Cross-sectional descriptive study. Madrid and Andalusia Regions, representative samples. The sample included 3,612 in secondary school pupils from Madrid (n=1708) and Andalusia (n=1904). The survey was carried out during May and June 2007. The data collected included sociodemographic areas (age, sex, grade, father's profession, birth place, etc.) and risk situation and behaviour (risk behaviour as driver or passenger). 16.2% of the adolescents have been involved in a dangerous situation with motorcycles during the last year. 16.7% never use a helmet when riding a motorcycle and 62% do not wear one when riding a bicycle on the road; 17.4% frequently ride a motorcycle over the speed limit and 24.5% when driving a car. There are significant differences regarding sex, grade and region (Madrid or Andalusia). There are four factors which explain 62% of the variance: drug factor, speed factor, security factor and passenger factor. Two of these have twice the probability of having a dangerous situation when riding a motorcycle: drug factor (OR=1.96; 95% CI, 1.77-2.18) and the speed factor ((OR=2.13; 95% CI, 1.92-2.36). Adolescents in higher grades and living in Andalusia were less road safety conscious. This pattern should be taken into account when designing preventive actions in Road Safety Education. 2009 Elsevier España, S.L. All rights reserved.

Nursing work often occurs in complex and potentially hazardous settings. Awareness of patient and practice environments is an imperative for nurses in practice. To explore nursing students' situation awareness while engaging in simulated patient deterioration scenarios. The educational process of FIRST(2)ACT was the model for the nurse intervention. Situation awareness was measured quantitatively using the Situation Awareness Global Assessment tool. Four domains were measured: physiological perception (patient parameters), global perception (surroundings), comprehension (interpretation of information), and projection (forecasting outcomes). Clinical laboratories at each of three participating universities. Ninety-seven nursing students from three Australian universities. Between March and July 2012, students participated in three video-recorded simulation events, in which a trained actor played patient roles and groups of three students worked as teams. To measure situation awareness, following the simulation each team leader was taken to a separate room and asked to report on a question set regarding the patient's vital signs, bedside setting and medical diagnosis. Overall, situation awareness was low (41%). Of the four domains, physiological perceptions scored the lowest (26%) and projection the highest (59%). Final year nursing students may not have well developed situation awareness skills, especially when dealing with these types of scenarios. Education providers need to consider ways to assist students to fully develop this attribute. Findings suggest that this is an aspect of undergraduate nursing education that requires significant consideration by curriculum developers. Crown Copyright © 2014. Published by Elsevier Ltd.

Full Text Available This study was conducted as a retrospective analysis of Northern Foods Plc., once a major player in FTSE 350 Food Sector, to evaluate its financial situation over a five year period. The ex post factor research design was used for this study. Annual reports and databases on Northern Foods Plc., and Associated British Foods Plc., were used to perform a series of ratio analyses. The results revealed that Northern Foods Plc.’s performance has been declining as evidenced in the profitability ratios calculated. Also, financial strength was weak and working capital has not been effectively managed, hence affecting its cash and profit generation potentials. The company was limited in its ability to grow and expand as it needed to regularly fund its pension deficit, and finance its high levels of debt. The study concludes that Northern Foods was not in a very strong financial position, yet it was not making the required investments to improve, hence its takeover though this paper will not rule out non-financial issues. Furthermore, the study prescribed five generic points to improve the financial health of any organisation.

Few studies have examined the health effects of employment situation among women, taking social and economic conditions into consideration. The objective of this research was to investigate the association of employment situation (full-time or part-time employee and self-employed) with mortality risk in women over a 20-year follow-up period. Additionally, we examined whether the association between employment situation and mortality in women differed by education level and marital status. We investigated the association of employment situation with mortality among 16,692 women aged 40-59 years enrolled in the Japan Collaborative Cohort Study. Multivariate HRs and 95% CIs for total deaths by employment situation were calculated after adjustment for age, disease history, residential area, education level, marital status and number of children. We also conducted subgroup analysis by education level and marital status. Multivariate HRs for mortality of part-time employees and self-employed workers were 1.48 (95% CI, 1.25 to 1.75) and 1.44 (95% CI, 1.21 to 1.72), respectively, with reference to women working full-time. Subgroup analysis by education level indicated that health effects in women according to employment situation were likely to be more evident in the low education-level group. Subgroup analysis by marital status indicated that this factor also affected the association between employment situation and risk of death. Among middle-aged Japanese women, employment situation was associated with mortality risk. Health effects were likely to differ by household structure and socioeconomic conditions.

Young, Kristie L; Stephens, Amanda N; Logan, David B; Lenné, Michael G

2017-04-01

Roadside advertising has the potential to create a crash risk for drivers as it may distract attention from driving at critical times. In an on-road instrumented vehicle study, we examined if and how static advertising billboards affect drivers' situation awareness across different driving environments. Nineteen fully licensed drivers drove an instrumented vehicle around a 38 km urban test route comprising freeway, busy urban retail and arterial road sections. The route contained a number of static billboards. Drivers provided continuous verbal protocols throughout the drive. Results indicated that the structure and content of drivers' situation awareness was not appreciably affected by the billboards in any of the road environments examined. Drivers focused their attention on the billboards when driving demand was low, such as when driving on the freeway with light to moderate traffic, in lower speed zones, or when stationary. However, when drivers were required to perform a manoeuvre or driving demands increased, drivers directed less attention to the billboards and focussed their awareness on the immediate driving task. This suggests that drivers can, at least under some conditions, effectively self-regulate their attention to billboards when required to focus on the immediate traffic or driving situation.

Ramadhani, Hilali Hussein

2016-04-01

This study was conducted to develop the Radiation protection Programme (RPP) to ensure that measures are in place for protection of individuals from the existing source of exposure. The study established a number of protective and remedial actions to be considered by the responsible regulatory Authority, licensee for existing exposure in workplace and dwellings. Tanzania is endowed with a number NORMs processing industries with an experience of uncontrolled exploration and extraction of minerals and the use of unsafe mining methods leading to severe environmental damage and appalling living conditions in the mining communities. Some of NORMs industries have been abandoned due to lack of an effect management infrastructure. The residual radioactive materials have been found to be the most import source of existing exposure resulted from NORMs industries. The Radon gas and its progeny have also been found to be a source of existing exposure from natural source as well as the major source of risk and health effects associated with existing exposure situation. The following measures have been discovered to play a pivotal role in avoiding or reducing the source of exposure to individuals such as restriction of the use of the construction materials, restriction on the consumption of foodstuffs and restriction on the access to the land and buildings, the removal of the magnitude of the source in terms of activity concentration as well as improvement of ventilation in dwellings. Therefore, the regulatory body (Tanzania Atomic Energy Commission) should examine the major areas outlined in the established RRP for existing exposure situation resulted from the NORMs industries and natural sources so as to develop strategies that will ensure the adequate protection of members of the public and the environment as well as guiding operating organizations to develop radiation protection and safety measures for workers.

Full Text Available In this research has been presented an assessment of safety situation in schools, examined through the attitudes of students and teachers of secondary schools in five municipalities of Tuzla Canton. The sample consisted of 160 subjects, who for the purposes of this research divided in three subsample: male students, female students and professors. The research was conducted as a questionnaire, where on the posted statements subjects chose one of five responses on the Likert-type scale. The results of the research showed that subjects generally have unfavour­able attitudes about security situation in secondary schools, which makes them feel very insecure. By descriptive analysis, besides these attitudes, it was determined that there are certain differences between the subsamples per individual variables. By analysis of variance, about influence of different status (student-professor on the sub-samples attitudes about safety in schools, it was determined that these differences were not statistically significant at the level p <.05 in results for the three subsample (F = .421, p = .245. In relation on manifested negative att­itudes about safety in schools, but also the homogeneity of results, in relation on the total sample of subjects, it is necessary to determine an adequate strategy of action, develop appropriate programs for work with students and make their prompt implementation in order to achieve safer living conditions and work in the school environment.

In mass-casualty situations, communications and information management to improve situational awareness is a major challenge for responders. In this study, the feasibility of a prototype system that utilizes commercially available, low-cost components, including Radio Frequency Identification (RFID) and mobile phone technology, was tested in two simulated mass-casualty incidents. The feasibility and the direct benefits of the system were evaluated in two simulated mass-casualty situations: one in Finland involving a passenger ship accident resulting in multiple drowning/hypothermia patients, and another at a major airport in Sweden using an aircraft crash scenario. Both simulations involved multiple agencies and functioned as test settings for comparing the disaster management's situational awareness with and without using the RFID-based system. Triage documentation was done using both an RFID-based system, which automatically sent the data to the Medical Command, and a traditional method using paper triage tags. The situational awareness was measured by comparing the availability of up-to date information at different points in the care chain using both systems. Information regarding the numbers and status or triage classification of the casualties was available approximately one hour earlier using the RFID system compared to the data obtained using the traditional method. The tested prototype system was quick, stable, and easy to use, and proved to work seamlessly even in harsh field conditions. It surpassed the paper-based system in all respects except simplicity of use. It also improved the general view of the mass-casualty situations, and enhanced medical emergency readiness in a multi-organizational medical setting. The tested technology is feasible in a mass-casualty incident; further development and testing should take place.

Marijuana-related problems and social anxiety: the role of marijuana behaviors in social situations.

Science.gov (United States)

Buckner, Julia D; Heimberg, Richard G; Matthews, Russell A; Silgado, Jose

2012-03-01

Individuals with elevated social anxiety appear particularly vulnerable to marijuana-related problems. In fact, individuals with social anxiety may be more likely to experience marijuana-related impairment than individuals with other types of anxiety. It is therefore important to determine whether constructs particularly relevant to socially anxious individuals play a role in the expression of marijuana-related problems in this vulnerable population. Given that both social avoidance and using marijuana to cope with negative affect broadly have been found to play a role in marijuana-related problems, the current study utilized a new measure designed to simultaneously assess social avoidance and using marijuana to cope in situations previously identified as anxiety-provoking among those with elevated social anxiety. The Marijuana Use to Cope with Social Anxiety Scale (MCSAS) assessed behaviors regarding 24 social situations: marijuana use to cope in social situations (MCSAS-Cope) and avoidance of social situations if marijuana was unavailable. In Study 1, we found preliminary support for the convergent and discriminant validity and internal consistency of the MCSAS scales. In Study 2, we examined if MCSAS scores were related to marijuana problems among those with (n = 44) and without (n = 44) clinically elevated social anxiety. Individuals with clinically meaningful social anxiety were more likely to use marijuana to cope in social situations and to avoid social situations if marijuana was unavailable. Of importance, MCSAS-Cope uniquely mediated the relationship between social anxiety group status and marijuana-related problems. Results highlight the importance of contextual factors in assessing marijuana-related behaviors among high-risk populations. PsycINFO Database Record (c) 2012 APA, all rights reserved.

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

Study on Reverse Reconstruction Method of Vehicle Group Situation in Urban Road Network Based on Driver-Vehicle Feature Evolution

Directory of Open Access Journals (Sweden)

Xiaoyuan Wang

2017-01-01

Full Text Available Vehicle group situation is the status and situation of dynamic permutation which is composed of target vehicle and neighboring traffic entities. It is a concept which is frequently involved in the research of traffic flow theory, especially the active vehicle security. Studying vehicle group situation in depth is of great significance for traffic safety. Three-lane condition was taken as an example; the characteristics of target vehicle and its neighboring vehicles were synthetically considered to restructure the vehicle group situation in this paper. The Gamma distribution theory was used to identify the vehicle group situation when target vehicle arrived at the end of the study area. From the perspective of driver-vehicle feature evolution, the reverse reconstruction method of vehicle group situation in the urban road network was proposed. Results of actual driving, virtual driving, and simulation experiments showed that the model established in this paper was reasonable and feasible.

Why do we laugh at misfortunes? An electrophysiological exploration of comic situation processing.

Manfredi, Mirella; Adorni, Roberta; Proverbio, Alice Mado; Proverbio, Alice

2014-08-01

The goal of the present study was to shed some light on a particular kind of humour, called slapstick, by measuring brain bioelectrical activity during the perception of funny vs. non-funny pictures involving misfortunate circumstances. According to our hypothesis, the element mostly providing a comic feature in a misfortunate situation is the facial expression of the victims: the observer׳s reaction will usually be laughing only if the victims will show a funny bewilderment face and not a painful or anger expression. Several coloured photographs depicting people involved in misfortunate situations were presented to 30 Italian healthy volunteers, while their EEG was recorded. Three different situations were considered: people showing a painful or an angry expression (Affective); people showing a bewilderment expression and, so, a comic look (Comic); people engaged in similar misfortunate situations but with no face visible (No Face). Results showed that the mean amplitude of both the posterior N170 and anterior N220 components was much larger in amplitude to comic pictures, than the other stimuli. This early response could be considered the first identification of a comic element and evidence of the compelling and automatic response that usually characterizes people amused reaction during a misfortune. In addition, we observed a larger P300 amplitude in response to comic than affective pictures, probably reflecting a more conscious processing of the comic element. Finally, no face pictures elicited an anteriorly distributed N400, which might reflect the effort to comprehend the nature of the situation displayed without any affective facial information, and a late positivity, possibly indexing a re-analysis processing of the unintelligible misfortunate situation (comic or unhappy) depicted in the No Face stimuli. These data support the hypothesis that the facial expression of the victims acts as a specific trigger for the amused feeling that observers usually

Texas situation

1986-01-01

The Texas Low-Level Radioactive Waste Disposal Authority was formed in 1981 to address the Texas low-level radioactive waste problem consistent with the direction of P.L. 96-573. The Authority has completed technical tasks, including source term evaluations, preliminary conceptual designs, economic assessments, and long-range planning, and has work in progress on facility design, site selection, operating procedures, and licensing. Site selection has been the major technical activity and will be completed in 1987 after on-site evaluations of potential sites. The Authority expects to have its site licensed and operating in 1992. Texas has been the leader in site selection. Political concerns and the uncertainty of the national agenda led Texas policy makers to slow down the state's progress. The lessons learned through the Texas situation should be instructive to other states and compacts and may well be a prediction of events for these other groups. This paper discusses the background and status of Texas development activities, future plans, and lessons learned

INCORPORATING ROUTINE ACTIVITIES, ACTIVITY SPACES, AND SITUATIONAL DEFINITIONS INTO THE SOCIAL SCHEMATIC THEORY OF CRIME*

Science.gov (United States)

BARR, ASHLEY B.; LEI, MAN-KIT; STEWART, ERIC

2014-01-01

Simons and Burt’s (2011) social schematic theory (SST) of crime posits that adverse social factors are associated with offending because they promote a set of social schemas (i.e., a criminogenic knowledge structure) that elevates the probability of situational definitions favorable to crime. This study extends the SST model by incorporating the role of contexts for action. Furthermore, the study advances tests of the SST by incorporating a measure of criminogenic situational definitions to assess whether such definitions mediate the effects of schemas and contexts on crime. Structural equation models using 10 years of panel data from 582 African American youth provided strong support for the expanded theory. The results suggest that childhood and adolescent social adversity fosters a criminogenic knowledge structure as well as selection into criminogenic activity spaces and risky activities, all of which increase the likelihood of offending largely through situational definitions. Additionally, evidence shows that the criminogenic knowledge structure interacts with settings to amplify the likelihood of situational definitions favorable to crime. PMID:26392633

Multi-robot missions are a challenge for operators in terms of workload and situational awareness. These operators have to receive data from the robots, extract information, understand the situation properly, make decisions, generate the adequate commands, and send them to the robots. The consequences of excessive workload and lack of awareness can vary from inefficiencies to accidents. This work focuses on the study of future operator interfaces of multi-robot systems, taking into account relevant issues such as multimodal interactions, immersive devices, predictive capabilities and adaptive displays. Specifically, four interfaces have been designed and developed: a conventional, a predictive conventional, a virtual reality and a predictive virtual reality interface. The four interfaces have been validated by the performance of twenty-four operators that supervised eight multi-robot missions of fire surveillance and extinguishing. The results of the workload and situational awareness tests show that virtual reality improves the situational awareness without increasing the workload of operators, whereas the effects of predictive components are not significant and depend on their implementation.

World petroleum demand is expected to increase from about 15 million barrels to 80 million after the year 2000. The resulting necessity to increase the currently over-extended global refining capacity will put a significant burden on financial resources within the industry. This article examines the developments, after a decade of restructuring, which have led to the present situation of the petroleum industry described as having greatly improved operational conditions but beset by worrisome problems with regard not only to capacity, but also to the costly constraints being imposed by new air pollution regulations, especially those relevant to desulfurization in refinery processes

Situation perception represents the fulcrum of a "psychology of situations" because situation ratings are ubiquitous. However, no systematic research program exists so far, particularly because two competing traditions have not been integrated: Objectivist views stress situations' consensually shared meanings (social reality), and subjectivist views idiosyncratic meanings (personal reality). A componential framework can disentangle social from personal reality in situation perceptions: When multiple perceivers (P) rate multiple situations (S) on multiple situation characteristics (C), variance in those ratings can be decomposed according to S × C, P × S, and P × C breakdowns. Six grand questions of situation perception research are spawned from these decompositions: complexity, similarity, assimilation, consensus, uniqueness, and accuracy. Analyses of real data are provided to exemplify our ideas, along with customizable R codes for all methods. A componential framework allows novel and unique insights into different questions surrounding situation perceptions and provides a coherent research agenda.
