    Full Text Available Conflict avoidance (CA plays a crucial role in guaranteeing the airspace safety. The current approaches, mostly focusing on a short-term situation which eliminates conflicts via local adjustment, cannot provide a global solution. Recently, long-term conflict avoidance approaches, which are proposed to provide solutions via strategically planning traffic flow from a global view, have attracted more attentions. With consideration of the situation in China, there are thousands of flights per day and the air route network is large and complex, which makes the long-term problem to be a large-scale combinatorial optimization problem with complex constraints. To minimize the risk of premature convergence being faced by current approaches and obtain higher quality solutions, in this work, we present an effective strategic framework based on a memetic algorithm (MA, which can markedly improve search capability via a combination of population-based global search and local improvements made by individuals. In addition, a specially designed local search operator and an adaptive local search frequency strategy are proposed to improve the solution quality. Furthermore, a fast genetic algorithm (GA is presented as the global optimization method. Empirical studies using real traffic data of the Chinese air route network and daily flight plans show that our approach outperformed the existing approaches including the GA based approach and the cooperative coevolution based approach as well as some well-known memetic algorithm based approaches.

    Zakaria, Chahnez; Curé, Olivier; Salzano, Gabriella; Smaïli, Kamel

    In Computer Supported Cooperative Work (CSCW), it is crucial for project leaders to detect conflicting situations as early as possible. Generally, this task is performed manually by studying a set of documents exchanged between team members. In this paper, we propose a full-fledged automatic solution that identifies documents, subjects and actors involved in relational conflicts. Our approach detects conflicts in emails, probably the most popular type of documents in CSCW, but the methods used can handle other text-based documents. These methods rely on the combination of statistical and ontological operations. The proposed solution is decomposed in several steps: (i) we enrich a simple negative emotion ontology with terms occuring in the corpus of emails, (ii) we categorize each conflicting email according to the concepts of this ontology and (iii) we identify emails, subjects and team members involved in conflicting emails using possibilistic description logic and a set of proposed measures. Each of these steps are evaluated and validated on concrete examples. Moreover, this approach's framework is generic and can be easily adapted to domains other than conflicts, e.g. security issues, and extended with operations making use of our proposed set of measures.

    Conflict avoidance plays a crucial role in guaranteeing the safety and efficiency of the air traffic management system. Recently, the strategic conflict avoidance (SCA) problem has attracted more and more attention. Taking into consideration the large-scale flight planning in a global view, SCA can be formulated as a large-scale combinatorial optimisation problem with complex constraints and tight couplings between variables, which is difficult to solve. In this paper, an SCA approach based on the cooperative coevolution algorithm combined with a new decomposition strategy is proposed to prevent the premature convergence and improve the search capability. The flights are divided into several groups using the new grouping strategy, referred to as the dynamic grouping strategy, which takes full advantage of the prior knowledge of the problem to better deal with the tight couplings among flights through maximising the chance of putting flights with conflicts in the same group, compared with existing grouping strategies. Then, a tuned genetic algorithm (GA) is applied to different groups simultaneously to resolve conflicts. Finally, the high-quality solutions are obtained through cooperation between different groups based on cooperative coevolution. Simulation results using real flight data from the China air route network and daily flight plans demonstrate that the proposed algorithm can reduce the number of conflicts and the average delay effectively, outperforming existing approaches including GAs, the memetic algorithm, and the cooperative coevolution algorithms with different well-known grouping strategies.

    2014-10-01

    The phenomenon of globalization and the increase in neo-extractivism in the global periphery intensify the search for new territories and natural resources for the economy, resulting in significant impacts on ecosystems and on the lives of vulnerable populations. It is considered that the environmental crisis imposes new challenges and requires an updating of the theoretical and methodological foundations of collective health and the social determinants of health. The scope of this paper is to present theoretical contributions to the construction of a critical socio-environmental approach from a review of the literature structured around previous work on the mapping of environmental conflicts, and conducting empirical studies in conflicting areas. The contributions of sociology, political ecology, postcolonial studies and geography is summarized for the discussion of the socio-environmental determinants of health, as well as experiences that integrate emancipatory knowledge, political subjects, resistances and alternatives for society.

  5. Case-based Reasoning in Conflict Negotiation in Concurrent Engineering

    1999-01-01

    Case-based reasoning (CBR) is a kind of analogous reasoning that is widely used in artificial intelligence. Conflicts are pervasive in Concurrent Engineering design environment. Conflict negotiation is necessary when conflicts occur. It is difficult to resolve conflicts due to several reasons. An approach to resolving conflicts by case-based reasoning is proposed in this paper. The knowledge representation of conflict negotiation cases, the judgment of case similarity, the retrieval model of cases, the management of case bases, and the process of case-based conflict negotiation are studied. The implementation structure of the Case-based Conflict Solving System (CCSS) is also given.

    2007-01-01

    We present a new methodology for detecting faults and abnormal behavior in production plants. The methodology stems from a joint project with a Danish energy consortium. During the course of the project we encountered several problems that we believe are common for projects of this type. Most...... system operation. Faults are detected by measuring the conflict between the model and the sensor readings, and knowledge about the possible faults is therefore not required. We illustrate the proposed method using real-world data from a coal driven power plant as well as simulated data from an oil...

  7. An Airborne Conflict Resolution Approach Using a Genetic Algorithm

    Mondoloni, Stephane; Conway, Sheila

    2001-01-01

    An airborne conflict resolution approach is presented that is capable of providing flight plans forecast to be conflict-free with both area and traffic hazards. This approach is capable of meeting constraints on the flight plan such as required times of arrival (RTA) at a fix. The conflict resolution algorithm is based upon a genetic algorithm, and can thus seek conflict-free flight plans meeting broader flight planning objectives such as minimum time, fuel or total cost. The method has been applied to conflicts occurring 6 to 25 minutes in the future in climb, cruise and descent phases of flight. The conflict resolution approach separates the detection, trajectory generation and flight rules function from the resolution algorithm. The method is capable of supporting pilot-constructed resolutions, cooperative and non-cooperative maneuvers, and also providing conflict resolution on trajectories forecast by an onboard FMC.

    Full Text Available The present study was to theorize about the process of coping with sexual disorders leading to marital conflicts. The process of coping with sexual disorders leading to marital conflicts was examined with 12 couples based on grounded theory. The focus of the study was on the period from commencing of symptoms up to start of treatment. Data were collected through semi-organized interviews and were analyzed through constant comparisons. It was recognized that problem solving skills was the main variable in the process of coping with sexual disorders leading to marital conflicts. The main variable consisted of two levels including ‘single-couple’ and ‘interactional’ and five main categories named as recognizing sexual disorder symptoms, personal assessment, self-attempt, threat feeling, consulting with others which ultimately led to searching help, consultation, and treatment. The preliminary individual decision to decrease the symptoms resulted in self-treatment which consequently defered the treatment period. Age, gender, education level, socio-economical status and pre-knowledge of disorders affected people`s decision making time. Individuals with sexual disorders defer the start of treatment and this can bring a family to separation. Couples should take pre-marriage counseling sessions in order to make decision for treatment at the right time when faced by sexual disorders.

  13. Nuclear Weapons in Russia's approach to conflict

    International Nuclear Information System (INIS)

    Johnson, Dave

    2016-11-01

    President Putin has moved nuclear weapons to the foreground of the European security landscape. New risks and dangers arise from the apparent coupling of nuclear weapons capabilities with Moscow's revanchist and irredentist foreign and defence policies toward its neighbours. Nuclear weapons are the central feature and capstone capability in Russia's evolving concept of strategic deterrence and are important tools for achieving Russia's geopolitical aims. Russian thinking on the role and place of nuclear weapons in upholding national security and in achieving strategic aims is reflected in military policy, force structure and posture, and exercises and operations. Russia's political and military leaders are not only re-conceptualising the role of nuclear weapons. They are also building the military capabilities that can credibly threaten the calibrated employment of nuclear weapons for deterrence, de-escalation and war-fighting from the regional to large-scale and global levels of conflict. New and still developing concepts for the employment of conventional long-range precision weapons in tandem with nuclear weapons for regional deterrence and containment of local and regional conflicts add volatility to the regional tensions and uncertainties created by recent Russian aggression. Russia's reliance upon integrated conventional and nuclear capabilities in reasserting its influence in its perceived sphere of special interest, intended to contain conflicts at a manageable level, could actually increase the risk of the potential employment of nuclear weapons. NATO nations collectively, and the three NATO nuclear powers (Great Britain, France, and the United States) individually, have recognized this new reality and have begun to adapt to it. In that context, the aim of this paper is to elaborate a clearer understanding of the place and role of nuclear weapons in Russia's approach to conflict, based on nuclear-related policy statements and military-theoretical writing

    Semantic conflict is the conflict caused by using different ways in heterogeneous systems to express the same entity in reality.This prevents information integration from accomplishing semantic coherence.Since ontology helps to solve semantic problems, this area has become a hot topic in information integration.In this paper, we introduce semantic conflict into information integration of heterogeneous applications.We discuss the origins and categories of the conflict, and present an ontology-based schema mapping approach to eliminate semantic conflicts.

  18. Modelling hen harrier dynamics to inform human-wildlife conflict resolution: a spatially-realistic, individual-based approach.

    Directory of Open Access Journals (Sweden)

    Johannes P M Heinonen

    Full Text Available Individual-based models have gained popularity in ecology, and enable simultaneous incorporation of spatial explicitness and population dynamic processes to understand spatio-temporal patterns of populations. We introduce an individual-based model for understanding and predicting spatial hen harrier (Circus cyaneus population dynamics in Great Britain. The model uses a landscape with habitat, prey and game management indices. The hen harrier population was initialised according to empirical census estimates for 1988/89 and simulated until 2030, and predictions for 1998, 2004 and 2010 were compared to empirical census estimates for respective years. The model produced a good qualitative match to overall trends between 1989 and 2010. Parameter explorations revealed relatively high elasticity in particular to demographic parameters such as juvenile male mortality. This highlights the need for robust parameter estimates from empirical research. There are clearly challenges for replication of real-world population trends, but this model provides a useful tool for increasing understanding of drivers of hen harrier dynamics and focusing research efforts in order to inform conflict management decisions.

  1. Community-based human-elephant conflict mitigation: The value of an evidence-based approach in promoting the uptake of effective methods.

    Directory of Open Access Journals (Sweden)

    Donny Gunaryadi

    Full Text Available Human-elephant conflict (HEC is a serious threat to elephants and can cause major economic losses. It is widely accepted that reduction of HEC will often require community-based methods for repelling elephants but there are few tests of such methods. We tested community-based crop-guarding methods with and without novel chili-based elephant deterrents and describe changes in farmers' willingness to adopt these methods following our demonstration of their relative effectiveness. In three separate field-trials that took place over almost two years (October 2005 -May 2007 in two villages adjacent to Way Kambas National Park (WKNP in Indonesia, we found that community-based crop-guarding was effective at keeping Asian elephants (Elephas maximus out of crop fields in 91.2% (52 out of 57, 87.6% (156 out of 178, and 80.0% (16 out of 20 of attempted raids. Once the method had been shown to be effective at demonstration sites, farmers in 16 villages around WKNP voluntarily adopted it during the July 2008 to March 2009 period and were able to repel elephants in 73.9% (150 out of 203 of attempted raids, with seven villages repelling 100% of attempted raids. These 16 villages had all experienced high levels of HEC in the preceding years; e.g. they accounted for >97% of the 742 HEC incidents recorded for the entire park in 2006. Our work shows, therefore, that a simple evidence-based approach can facilitate significant reductions in HEC at the protected area scale.

    Full Text Available Due to the economic, social and cultural changes in recent decades and consequently alterations in the form and duties of families and expectations of individuals from marriage, the institution of the family and marriage are enormously involved with different challenges and conflicts in comparison to past years. Fragile marital relationships, conflicts and divorce are results of such situations in Iran. Accordingly, the present study, which is designed through meta-analysis and deduction based on the concept analysis and reconceptualization of recent studies, has committed to manifest a proper different paradigm to explain marital conflicts. This paradigm is relying on various theoretical approaches, particularly the theory of symbolic interactionism as the main explanatory mean, and also applying the concept of “Marital Paradigm” as the missing information in previous studies of this field. It explains the marital conflicts between couples as paradigmatic conflicts; and its main idea is that marital conflict is not the result of one or more fixed and specified factors, but it is the production of encountering the opposing (or different paradigms.

    In this work, the authors have not focused directly on the United States-Soviet conflict but on regional conflicts that have obvious repercussions on the relations between the superpowers. Apart from some work on the Cyprus conflict, my major efforts in recent years have concentrated on the Middle East conflict. This work relates to the goal of avoiding nuclear war in at least two respects. First, given the high degree of superpower involvement in all the globe's trouble spots, regional conflicts present the danger of escalating United States-Soviet confrontation that might touch off an unintentional military exchange-an exchange that might start with conventional weapons and move on to nuclear ones. The danger that the superpowers might inadvertently, through a succession of small commitments, be drawn into a regional war is probably greater in the Middle East than in any other area of the world. Second, the orientation and techniques that they have been developing can be applied, with appropriate adaptations, to efforts to manage and resolve the United States-Soviet conflict

    Animal approach-avoidance conflict paradigms have been used extensively to operationalize anxiety, quantify the effects of anxiolytic agents, and probe the neural basis of fear and anxiety. Results from human neuroimaging studies support that a frontal-striatal-amygdala neural circuitry is important for approach-avoidance learning. However, the neural basis of decision-making is much less clear in this context. Thus, we combined a recently developed human approach-avoidance paradigm with functional magnetic resonance imaging (fMRI) to identify neural substrates underlying approach-avoidance conflict decision-making. Fifteen healthy adults completed the approach-avoidance conflict (AAC) paradigm during fMRI. Analyses of variance were used to compare conflict to non-conflict (avoid-threat and approach-reward) conditions and to compare level of reward points offered during the decision phase. Trial-by-trial amplitude modulation analyses were used to delineate brain areas underlying decision-making in the context of approach/avoidance behavior. Conflict trials as compared to the non-conflict trials elicited greater activation within bilateral anterior cingulate cortex (ACC), anterior insula, and caudate, as well as right dorsolateral prefrontal cortex. Right caudate and lateral PFC activation was modulated by level of reward offered. Individuals who showed greater caudate activation exhibited less approach behavior. On a trial-by-trial basis, greater right lateral PFC activation related to less approach behavior. Taken together, results suggest that the degree of activation within prefrontal-striatal-insula circuitry determines the degree of approach versus avoidance decision-making. Moreover, the degree of caudate and lateral PFC activation is related to individual differences in approach-avoidance decision-making. Therefore, the AAC paradigm is ideally suited to probe anxiety-related processing differences during approach-avoidance decision-making. PMID:25224633

  12. Sensory conflict in motion sickness: An observer theory approach

    Science.gov (United States)

    Oman, Charles M.

    1989-01-01

    Motion sickness is the general term describing a group of common nausea syndromes originally attributed to motion-induced cerebral ischemia, stimulation of abdominal organ afferent, or overstimulation of the vestibular organs of the inner ear. Sea-, car-, and airsicknesses are the most commonly experienced examples. However, the discovery of other variants such as Cinerama-, flight simulator-, spectacle-, and space sickness in which the physical motion of the head and body is normal or absent has led to a succession of sensory conflict theories which offer a more comprehensive etiologic perspective. Implicit in the conflict theory is the hypothesis that neutral and/or humoral signals originate in regions of the brain subversing spatial orientation, and that these signals somehow traverse to other centers mediating sickness symptoms. Unfortunately, the present understanding of the neurophysiological basis of motion sickness is far from complete. No sensory conflict neuron or process has yet been physiologically identified. To what extent can the existing theory be reconciled with current knowledge of the physiology and pharmacology of nausea and vomiting. The stimuli which causes sickness, synthesizes a contemporary Observer Theory view of the Sensory Conflict hypothesis are reviewed, and a revised model for the dynamic coupling between the putative conflict signals and nausea magnitude estimates is presented. The use of quantitative models for sensory conflict offers a possible new approach to improving the design of visual and motion systems for flight simulators and other virtual environment display systems.

    Two distinct and parallel research communities have been working along the lines of the model-based diagnosis approach: the fault detection and isolation (FDI) community and the diagnostic (DX) community that have evolved in the fields of automatic control and artificial intelligence, respectively. This paper clarifies and links the concepts and assumptions that underlie the FDI analytical redundancy approach and the DX consistency-based logical approach. A formal framework is proposed in order to compare the two approaches and the theoretical proof of their equivalence together with the necessary and sufficient conditions is provided.

    2016-12-01

    Full Text Available A land use regime undergoes much change over time depending on the growth in the importance of various interest groups. Spatial conflicts repeatedly accompany this growth. The aim of the article is to determine the relationship between spatial conflicts and landscape changes. On the basis of the Silesian and Żywiec Beskid mountain ranges, it has been proven that conflicts arising between mountain grazing, agriculture, forest management, contemporary building and tourism development have significant impacts on the landscape. To this end, archive and contemporary cartographic materials, historical scientific works and archive photographs were used. The conflicts between mountain grazing and other types of human activity in the study area were analysed. Subsequently, their influence on the landscape was determined. As a result of the study, the primary sources of conflicts were indicated and correlated with historical periods and the predominant landscape use regime. The imprints of historical space conflicts and the rivalry for land use between different entities for their own purposes are still visible in the landscape. The historical conflicts have arisen between entities seeking ways to use different environmental resources occurring in the same area. Contemporary conflicts arise between entities seeking ways to use environmental resources (tourism and between entities conscious of the hazards of the landscape sustainability resulting from the utilization of environmental resources (nature conservation services. Both historical and contemporary conflicts usually have a violent course resulting from the lack, or deficiency of, legislation concerning land management.

    Hagen, George E.; Butler, Ricky W.; Maddalon, Jeffrey M.

    2011-01-01

    In this paper we introduce Stratway, a modular approach to finding long-term strategic resolutions to conflicts between aircraft. The modular approach provides both advantages and disadvantages. Our primary concern is to investigate the implications on the verification of safety-critical properties of a strategic resolution algorithm. By partitioning the problem into verifiable modules much stronger verification claims can be established. Since strategic resolution involves searching for solutions over an enormous state space, Stratway, like most similar algorithms, searches these spaces by applying heuristics, which present especially difficult verification challenges. An advantage of a modular approach is that it makes a clear distinction between the resolution function and the trajectory generation function. This allows the resolution computation to be independent of any particular vehicle. The Stratway algorithm was developed in both Java and C++ and is available through a open source license. Additionally there is a visualization application that is helpful when analyzing and quickly creating conflict scenarios.

  18. An ethical approach to resolving value conflicts in child protection.

    Science.gov (United States)

    Webb, E; Moynihan, S

    2010-01-01

    Child protection professionals working in diverse societies are regularly faced with value conflicts. Recognising these, and resolving them in the best interests of children, is a task that requires child protection specialists to make complex judgements and decisions. In this paper the philosophical concepts of absolutism and relativism to child abuse are applied, and it explores how this approach has practical relevance to solving ethical dilemmas in child protection. Children's interests are best served by erring towards an absolutist approach to the diagnosis and recognition of maltreatment and towards a relativistic approach in determining how services respond to a harmful incident or situation. Absolutism and relativism are not alternatives, but part of a continuous process of recognising and negotiating ever-changing community, national and global norms. At the service level the dichotomy transpires into the need to be culturally competent in handling the conflicting needs, rights and values of children, families, communities and professionals, whilst retaining the skill of child advocacy.

    Kirlic, Namik; Young, Jared; Aupperle, Robin L

    2017-09-01

    Avoidance behavior in clinical anxiety disorders is often a decision made in response to approach-avoidance conflict, resulting in a sacrifice of potential rewards to avoid potential negative affective consequences. Animal research has a long history of relying on paradigms related to approach-avoidance conflict to model anxiety-relevant behavior. This approach includes punishment-based conflict, exploratory, and social interaction tasks. There has been a recent surge of interest in the translation of paradigms from animal to human, in efforts to increase generalization of findings and support the development of more effective mental health treatments. This article briefly reviews animal tests related to approach-avoidance conflict and results from lesion and pharmacologic studies utilizing these tests. We then provide a description of translational human paradigms that have been developed to tap into related constructs, summarizing behavioral and neuroimaging findings. Similarities and differences in findings from analogous animal and human paradigms are discussed. Lastly, we highlight opportunities for future research and paradigm development that will support the clinical utility of this translational work. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2011-09-01

    Conflict management has been identified as an essential competence for surgeons as they work in operating room (OR) teams; however, the optimal approach is unclear. Social science research offers two alternatives, the first of which recommends that task-related conflict be managed using problem-solving techniques while avoiding relationship conflict. The other approach advocates for the active management of relationship conflict as it almost always accompanies task-related conflict. Clarity about the optimal management strategy can be gained through a better understanding of conflict transformation, or the inter-relationship between conflict types, in this specific setting. The purpose of this study was to evaluate conflict transformation in OR teams in order to clarify the approach most appropriate for an educational conflict management programme for surgeons. A constructivist grounded theory approach was adopted to explore the phenomenon of OR team conflict. Narratives were collected from focus groups of OR nurses and surgeons at five participating centres. A subset of these narratives involved transformation between and within conflict types. This dataset was analysed. The results confirm that misattribution and the use of harsh language cause conflict transformation in OR teams just as they do in stable work teams. Negative emotionality was found to make a substantial contribution to responses to and consequences of conflict, notably in the swiftness with which individuals terminated their working relationships. These findings contribute to a theory of conflict transformation in the OR team. There are a number of behaviours that activate conflict transformation in the OR team and a conflict management education programme should include a description of and alternatives to these behaviours. The types of conflict are tightly interwoven in this setting and thus the most appropriate management strategy is one that assumes that both types of conflict will exist and

  9. Evidence conflict measure based on OWA operator in open world.

    Directory of Open Access Journals (Sweden)

    Wen Jiang

    Full Text Available Dempster-Shafer evidence theory has been extensively used in many information fusion systems since it was proposed by Dempster and extended by Shafer. Many scholars have been conducted on conflict management of Dempster-Shafer evidence theory in past decades. However, how to determine a potent parameter to measure evidence conflict, when the given environment is in an open world, namely the frame of discernment is incomplete, is still an open issue. In this paper, a new method which combines generalized conflict coefficient, generalized evidence distance, and generalized interval correlation coefficient based on ordered weighted averaging (OWA operator, to measure the conflict of evidence is presented. Through ordered weighted average of these three parameters, the combinatorial coefficient can still measure the conflict effectively when one or two parameters are not valid. Several numerical examples demonstrate the effectiveness of the proposed method.

    Full Text Available The purpose of this study was to determine the association between deaths owing to terrorism, civil war and one-sided violence from 1994–2000 and disability-adjusted life years (DALYs attributable to diarrheal and related diseases, schistosomiasis, trachoma and the nematode infections (DSTN diseases in 2002 among World Health Organization Member States. Deaths resulting from terrorism, civil war and one-sided violence were significantly related to DSTN DALYs across the majority of sex–age subgroups of the populace, after controlling for baseline levels of improved water/sanitation and a variety of economic measures: overall, a 1.0% increase in deaths owing to terrorism and related violence was associated with an increase of 0.16% in DALYs lost to DSTN diseases. Associations were greatest among 0-to-4-year olds. The results of the present study suggest that DSTN disease control efforts should target conflict-affected populations with particular attention to young children who suffer disproportionately from DSTN diseases in these settings. In view of the evidence that terrorism and related violence may influence DSTN DALYs in the longer term, control strategies should move beyond immediate responses to decrease the incidence and severity of DSTN diseases to seek solutions through bolstering health systems infrastructure development among conflict-affected populations.

  11. A strategic approach for managing conflict in hospitals: responding to the Joint Commission leadership standard, Part 1.

    Science.gov (United States)

    Scott, Charity; Gerardi, Debra

    2011-02-01

    The Joint Commission's leadership standard for conflict management in hospitals, LD.02.04.01, states, "The hospital manages conflict between leadership groups to protect the quality and safety of care." This standard is one of numerous standards and alerts issued by The Joint Commission that address conflict and communication. They underscore the significant impact of relational dynamics on patient safety and quality of care and the critical need for a strategic approach to conflict in health care organizations. Whether leadership conflicts openly threaten a major disruption of hospital operations or whether unresolved conflicts lurk beneath the surface of daily interactions, unaddressed conflict can undermine a hospital's efforts to ensure safe, high-quality patient care. How leaders manage organizational conflict has a significant impact on achieving strategic objectives. Aligning conflict management approaches with quality and safety goals is the first step in adopting a strategic approach to conflict management. A strategic approach goes beyond reducing costs of litigation or improving grievance processes--it integrates a collaborative mind-set and individual conflict competency with nonadversarial processes. Conflict assessment should determine how conflicts are handled among the leaders at the hospital, the degree of conflict competence already present among the leaders, where the most significant conflicts occur, and how leaders think a conflict management system might work for them. Strategically aligning a conflict management approach that addresses conflict among leadership groups as a means of protecting the quality and safety of patient care is at the heart of LD.02.04.01.

    2013-01-01

    State-based conflict detection and resolution (CD&R) algorithms detect conflicts and resolve them on the basis on current state information without the use of additional intent information from aircraft flight plans. Therefore, the prediction of the trajectory of aircraft is based solely upon the position and velocity vectors of the traffic aircraft. Most CD&R algorithms project the traffic state using only the current state vectors. However, the past state vectors can be used to make a better prediction of the future trajectory of the traffic aircraft. This paper explores the idea of using past state vectors to detect traffic turns and resolve conflicts caused by these turns using a non-linear projection of the traffic state. A new algorithm based on this idea is presented and validated using a fast-time simulator developed for this study.

    The purpose of this study was to investigate the relationship between self-concept and locus of control in interpersonal conflict resolution approaches and to determine the predictors of conflict resolution approach choices. The study included 345 students aged between 18 and 28 years that were studying at universities in Ankara. Data were collected using the Interpersonal Conflict Resolution Approaches Scale to measure conflict resolution approaches, the Social Comparison Scale to measure self-concept, and the Internal-External Locus of Control Scale to measure locus of control. It was observed that confrontation approach to interpersonal conflict was predicted by self-concept (beta = 0.396, P resolution approaches. In addition to these findings, it was observed that females used self-disclosure (beta = -0.163, P resolution processes. Self-concept and locus of control were related to the behaviors adopted in the interpersonal conflict resolution process. Individuals with a positive self-concept and an internal locus of control adopted solutions to interpersonal conflict resolution that were more effective and constructive.

    2017-01-01

    The motivational dimensional model of affect proposes that the influence of positive affect on cognitive processing is modulated by approach-motivational intensity. The present research extended this model by examining the influence of positive affect varying in approach-motivational intensity on conflict resolution-the ability to resolve interference from task-irrelevant distractors in order to focus on the target. The global-local task (Experiment 1) and letter-Flanker task (Experiment 2) were used to measure conflict resolution. Additionally, the 4:2 mapping design that assigns two kinds of task-relevant stimuli to one response key and two more to another response key was used in these two tasks to dissociate stimulus and response conflict. Results showed that positive affect varying in approach motivation had opposite influences on conflict resolution. The opposite influences are primarily reflected in low approach-motivated positive affect impairing, while high approach-motivated positive affect facilitating the resolution of response conflict. Conversely, the stimulus conflict was slightly influenced. These findings highlight the utility of distinguishing stimulus and response conflict in future research.

  1. Conflict Resolution for Product Performance Requirements Based on Propagation Analysis in the Extension Theory

    Directory of Open Access Journals (Sweden)

    Yanwei Zhao

    2014-01-01

    Full Text Available Traditional product data mining methods are mainly focused on the static data. Performance requirements are generally met as possible by finding some cases and changing their structures. However, when one is satisfied with the structures changed, the other effects are not taken into account by analyzing the correlations; that is, design conflicts are not identified and resolved. An approach to resolving the conflict problems is proposed based on propagation analysis in Extension Theory. Firstly, the extension distance is improved to better fit evaluating the similarity among cases, then, a case retrieval method is developed. Secondly, the transformations that can be made on selected cases are formulated by understanding the conflict natures in the different performance requirements, which leads to the extension transformation strategy development for coordinating conflicts using propagation analysis. Thirdly, the effects and levels of propagation are determined by analyzing the performance values before and after the transformations, thus the co-existing conflict coordination strategy of multiple performances is developed. The method has been implemented in a working prototype system for supporting decision-making. And it has been demonstrated the feasible and effective through resolving the conflicts of noise, exhaust, weight and intake pressure for the screw air compressor performance design.

    Ma, Yong; Wang, Hongwei; Zamirian, M.

    2012-01-01

    We present a new approach containing two steps to determine conflict-free paths for mobile objects in two and three dimensions with moving obstacles. Firstly, the shortest path of each object is set as goal function which is subject to collision-avoidance criterion, path smoothness, and velocity and acceleration constraints. This problem is formulated as calculus of variation problem (CVP). Using parametrization method, CVP is converted to time-varying nonlinear programming problems (TNLPP) and then resolved. Secondly, move sequence of object is assigned by priority scheme; conflicts are resolved by multilevel conflict resolution strategy. Approach efficiency is confirmed by numerical examples. -- Highlights: ► Approach with parametrization method and conflict resolution strategy is proposed. ► Approach fits for multi-object paths planning in two and three dimensions. ► Single object path planning and multi-object conflict resolution are orderly used. ► Path of each object obtained with parameterization method in the first phase. ► Conflict-free paths gained by multi-object conflict resolution in the second phase.

Design/methodology/approach: Research method is descriptive - applied. The statistical population includes all of the employees in Iran`s Azad Universites with 600 individuals at the time of the study and statistical sample included 234 individuals who were selected using Morgan table. Beside this study, descriptive and inferential statistics were used. Also, reliability approved through Cronbach alpha (0.87. Then, to detect the dimensions causes of organizational conflict, factor analysis in line with the main components was used. Through exploratory analysis, ten principal factors identified. Thereafter, confirmatory factor analysis reconfirmed these factors. Findings and originality/value: The results of study showed that there is no significant difference between the causes of organizational conflict based on the gender. Also, there are significant differences among the causes of organizational conflict based on the variables of age, education and work experience. Research limitations/implications: we adopt a cross sectional research design and as a result inferences regarding causality cannot be drawn. Future studies following a longitudinal design could provide a more dynamic perspective and contribute further to this stream of research. Originality/value: A lot of researches about the conflict management styles, organizational conflict's effects, etc. are conducted by different researchers, but a handful of researches have been conducted in the field of resources and causes of organizational conflict and this is one of the reasons that it is important for researchers to address this issue.

    The force of the ethnic separatism, essentially originating from the negative effect of ethnic identity, is damaging the stability and harmony of multiethnic countries. In order to eliminate the foundation of the ethnic separatism and set up a harmonious ethnic relationship, some scholars have proposed a viewpoint: ethnic harmony could be promoted by popularizing civic identity. However, this viewpoint is discussed only from a philosophical prospective and still lacks support of scientific evidences. Because ethnic group and ethnic identity are products of evolution and ethnic identity is the parochialism strategy under the perspective of game theory, this paper proposes an evolutionary game simulation model to study the relationship between civic identity and ethnic conflict based on evolutionary game theory. The simulation results indicate that: (1) the ratio of individuals with civic identity has a negative association with the frequency of ethnic conflicts; (2) ethnic conflict will not die out by killing all ethnic members once for all, and it also cannot be reduced by a forcible pressure, i.e., increasing the ratio of individuals with civic identity; (3) the average frequencies of conflicts can stay in a low level by promoting civic identity periodically and persistently.

    2013-10-01

    We explore whether the visual presentation of relative position vectors (RPVs) improves conflict detection in conditions representing some aspects of future airspace concepts. To help air traffic controllers manage increasing traffic, new tools and systems can automate more cognitively demanding processes, such as conflict detection. However, some studies reveal adverse effects of such tools, such as reduced situation awareness and increased workload. New displays are needed that help air traffic controllers handle increasing traffic loads. A new display tool based on the display of RPVs, the Multi-Conflict Display (MCD), is evaluated in a series of simulated conflict detection tasks. The conflict detection performance of air traffic controllers with the MCD plus a conventional plan-view radar display is compared with their performance with a conventional plan-view radar display alone. Performance with the MCD plus radar was better than with radar alone in complex scenarios requiring controllers to find all actual or potential conflicts, especially when the number of aircraft on the screen was large. However performance with radar alone was better for static scenarios in which conflicts for a target aircraft, or target pair of aircraft, were the focus. Complementing the conventional plan-view display with an RPV display may help controllers detect conflicts more accurately with extremely high aircraft counts. We provide an initial proof of concept that RPVs may be useful for supporting conflict detection in situations that are partially representative of conditions in which controllers will be working in the future.

  9. Teaching a Relational Approach to Climate Change: Working with People and Conflict

    2015-12-01

    In 2010, science and technology studies expert Sheila Jasanoff concluded an article in Science by observing that the scientific community "…has demonstrated that it can learn and change in its methods of representing science to scientists. That ingenuity should now be directed toward building relationships of trust and respect with the global citizens whose future climate science has undertaken to predict and reshape." This kind of statement indicates a large shift in the focus on climate-related work, in a sense concluding that the scientific conclusions are well-established, but there is a human-to-human, relationship-based element of the work that needs attention. At the same time, there is increasing emphasis on transitioning to more participatory models of research, practice, and engagement in climate work, the human relationships that underlie these approaches are rarely explicitly addressed. For example, conflict, a key relational process, is often an inevitable element of engagement in societal processes. Although conflict can lead toward more successful long-term solutions if addressed constructively, dealing with it can be highly uncomfortable on an individual level and is often avoided. Acknowledging the often pivotal role conflict plays in eventual solutions bolsters the notion of complementing current training with a focus on relationship building. Professional development to increase relational capacity is being adopted in fields such as law and medicine; these same approaches are also increasingly relevant for climate practitioners where strong emotions such as grief and anxiety are often present for both practitioners and those they interact with. A framework for teaching and learning to effectively interact in this rich, relational world will be presented.

    Gender-based violence (GBV) is prevalent among, though not specific to, conflict affected populations and related to multifarious levels of vulnerability of conflict and displacement. Colombia has been marked with decades of conflict, with an estimated 5.2 million internally displaced persons (IDPs) and ongoing violence. We conducted qualitative research to understand the contexts of conflict, displacement and dynamics with GBV. This as part of a multi-phase, mixed method study, in collaboration with UNHCR, to develop a screening tool to confidentially identify cases of GBV for referral among IDP women who were survivors of GBV. Qualitative research was used to identify the range of GBV, perpetrators, contexts in conflict and displacement, barriers to reporting and service uptake, as well as to understand experiences of service providers. Thirty-five female IDPs, aged 18 years and older, who self-identified as survivors of GBV were enrolled for in-depth interviews in San Jose de Guaviare and Quibdo, Colombia in June 2012. Thirty-one service providers participated in six focus group discussions and four interviews across these sites. Survivors described a range of GBV across conflict and displacement settings. Armed actors in conflict settings perpetrated threats of violence and harm to family members, child recruitment, and, to a lesser degree, rape and forced abortion. Opportunistic violence, including abduction, rape, and few accounts of trafficking were more commonly reported to occur in the displacement setting, often perpetrated by unknown individuals. Intrafamilial violence, intimate partner violence, including physical and sexual violence and reproductive control were salient across settings and may be exacerbated by conflict and displacement. Barriers to reporting and services seeking were reported by survivors and providers alike. Findings highlight the need for early identification of GBV cases, with emphasis on confidential approaches and active

    Full Text Available There is a tendency of similar idea that caught the conflict prevention and management efforts nowadays to the articles of the Charter of Medina which was religious-based and containing the theory of civil society. It I mostly on the handling of conflict which tends to take preventive measures and to stop the conflict directly, as well as making a comprehensive synergistic effort to mange conflict. Conflict prevention is a core component of a comprehensive Conflict Management Program. This paper explores the conflict that occurred in Ponianak between a group of people from ethnic Dayak and members of an Islamic organization in 2012 which includes an important lesson for the people of West Kalimantan, both for the government and the community elements especially in dealing with a dispute between different groups of people. An integrative prevention has been proven to be able to answer the question of handling a conflict that has a potential to escalate into a full-scale riot. This work concludes that an integrative conflict handling model may become a viable alternative model to be adopted by the community of West Kalimantan in particular and other societies in general. A synergic integrative conflict handling model that reflects local wisdom of the people of Pontianak is expected to inspire real peace for various communities with a multicultural background.

    1994-01-01

    This paper describes two techniques, created and implemented in the course of development of the real-time on-line expert system Recon at the Nuclear Research Institute at Rez, Czech Republic. The first of them is the qualitative processing of uncertainty, which is based on the introduction of the third logic value to logic data objects, and the credibility flag to arithmetic data objects. The treatment of the third value and credibility flags during the inference, the explanation method based on the graphic representation and the uncertainty processing during the explanation are also mentioned. The second technique, is a semantic checking of knowledge bases, which enables us to recover parts of the bases, that are meaningless, either because of an error during their implementation into a base, or because they are redundant. The paper includes the explanation of basic terms of this method, such as so called conflicts, K-group and K-situation. The two types of the conflict (dead-end and bubble) are also discussed. The paper also offers the complete mathematical apparatus, which the checking method is based on. (author). 4 refs, tabs

    Conflicting constellations and the resulting risk of conflict over raw materials are highly complex. This report investigates approaches of various groups of actors and various fields of politics to minimize this risk, with the intention of identifying and analyzing relevant and innovative approaches and to outline their potential and shortcomings in solving risky constellations. The approaches presented here were selected for their relevance and actuality. This includes, on the one hand, approaches that investigate violent conflicts in the producer countries. On the other hand, approaches are considered that attempt to influence the risk of conflict by governmental or private environmental, climate and resources policies. (orig./RHM)

    Addiction is characterized by persistence to seek drug reinforcement despite negative consequences. Drug-induced aberrations in approach and avoidance processing likely facilitate the sustenance of addiction pathology. Currently, the effects of repeated drug exposure on the resolution of conflicting approach and avoidance motivational signals have yet to be thoroughly investigated. The present study sought to investigate the effects of cocaine pre-exposure on conflict resolution using novel approach-avoidance paradigms. We used a novel mixed-valence conditioning paradigm to condition cocaine-pre-exposed rats to associate visuo-tactile cues with either the delivery of sucrose reward or shock punishment in the arms in which the cues were presented. Following training, exploration of an arm containing a superimposition of the cues was assessed as a measure of conflict resolution behavior. We also used a mixed-valence runway paradigm wherein cocaine-pre-exposed rats traversed an alleyway toward a goal compartment to receive a pairing of sucrose reward and shock punishment. Latency to enter the goal compartment across trials was taken as a measure of motivational conflict. Our results reveal that cocaine pre-exposure attenuated learning for the aversive cue association in our conditioning paradigm and enhanced preference for mixed-valence stimuli in both paradigms. Repeated cocaine pre-exposure allows appetitive approach motivations to gain greater influence over behavioral output in the context of motivational conflict, due to aberrant positive and negative incentive motivational processing.

  20. Valence evaluation with approaching or withdrawing cues: directly testing valence-arousal conflict theory.

    Science.gov (United States)

    Wang, Yan Mei; Li, Ting; Li, Lin

    2017-07-19

    The valence-arousal conflict theory assumes that both valence and arousal will trigger approaching or withdrawing tendencies. It also predicts that the speed of processing emotional stimuli will depend on whether valence and arousal trigger conflicting or congruent motivational tendencies. However, most previous studies have provided evidence of the interaction between valence and arousal only, and have not provided direct proof of the interactive links between valence, arousal and motivational tendencies. The present study provides direct evidence for the relationship between approach-withdrawal tendencies and the valence-arousal conflict. In an empirical test, participants were instructed to judge the valence of emotional words after visual-spatial cues that appeared to be either approaching or withdrawing from participants. A three-way interaction (valence, arousal, and approach-withdrawal tendency) was observed such that the response time was shorter if participants responded to a negative high-arousal stimulus after a withdrawing cue, or to a positive low-arousal stimulus after an approaching cue. These findings suggest that the approach-withdrawal tendency indeed plays a crucial role in valence-arousal conflict, and that the effect depends on the congruency of valence, arousal and tendency at an early stage of processing.

    We examined the relations between interparental conflict (destructive and constructive), parenting behaviors (harshness and supportiveness) and children's emotional insecurity in early childhood when children were approximately 36 months of age. The sample consisted of low-income unmarried couples who were expectant/new parents who participated in the national Building Strong Families project. Interparental conflict was assessed through parents' reported perception of the other parent's conflict behavior. Parenting behaviors were measured through observational data, and children's emotional insecurity was based on parents' reports. Using latent profile analysis, three goals were addressed: (a) concordance or discord of mothers' and fathers' conflict behaviors, (b) the relation between couples' conflict behaviors and parenting, and (c) the association between couples' conflict behaviors and child emotional insecurity. Our findings revealed 4 profiles of couples that share similar characteristics, which in turn were differentially linked to aspects of parenting and child development. Further, results indicated that the vast majority of low-income unmarried couples engage in constructive conflict management behaviors. These findings highlight the need to consider the family unit when designing interventions or providing counseling. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    Rodent models of anxiety have implicated the ventral hippocampus in approach-avoidance conflict processing. Few studies have, however, examined whether the human hippocampus plays a similar role. We developed a novel decision-making paradigm to examine neural activity when participants made approach/avoidance decisions under conditions of high or absent approach-avoidance conflict. Critically, our task required participants to learn the associated reward/punishment values of previously neutral stimuli and controlled for mnemonic and spatial processing demands, both important issues given approach-avoidance behavior in humans is less tied to predation and foraging compared to rodents. Participants played a points-based game where they first attempted to maximize their score by determining which of a series of previously neutral image pairs should be approached or avoided. During functional magnetic resonance imaging, participants were then presented with novel pairings of these images. These pairings consisted of images of congruent or opposing learned valences, the latter creating conditions of high approach-avoidance conflict. A data-driven partial least squares multivariate analysis revealed two reliable patterns of activity, each revealing differential activity in the anterior hippocampus, the homolog of the rodent ventral hippocampus. The first was associated with greater hippocampal involvement during trials with high as opposed to no approach-avoidance conflict, regardless of approach or avoidance behavior. The second pattern encompassed greater hippocampal activity in a more anterior aspect during approach compared to avoid responses, for conflict and no-conflict conditions. Multivoxel pattern classification analyses yielded converging findings, underlining a role of the anterior hippocampus in approach-avoidance conflict decision making. Approach-avoidance conflict has been linked to anxiety and occurs when a stimulus or situation is associated with reward

  3. Dynamic Allocation of SPM Based on Time-Slotted Cache Conflict Graph for System Optimization

    Science.gov (United States)

    Wu, Jianping; Ling, Ming; Zhang, Yang; Mei, Chen; Wang, Huan

    This paper proposes a novel dynamic Scratch-pad Memory allocation strategy to optimize the energy consumption of the memory sub-system. Firstly, the whole program execution process is sliced into several time slots according to the temporal dimension; thereafter, a Time-Slotted Cache Conflict Graph (TSCCG) is introduced to model the behavior of Data Cache (D-Cache) conflicts within each time slot. Then, Integer Nonlinear Programming (INP) is implemented, which can avoid time-consuming linearization process, to select the most profitable data pages. Virtual Memory System (VMS) is adopted to remap those data pages, which will cause severe Cache conflicts within a time slot, to SPM. In order to minimize the swapping overhead of dynamic SPM allocation, a novel SPM controller with a tightly coupled DMA is introduced to issue the swapping operations without CPU's intervention. Last but not the least, this paper discusses the fluctuation of system energy profit based on different MMU page size as well as the Time Slot duration quantitatively. According to our design space exploration, the proposed method can optimize all of the data segments, including global data, heap and stack data in general, and reduce the total energy consumption by 27.28% on average, up to 55.22% with a marginal performance promotion. And comparing to the conventional static CCG (Cache Conflicts Graph), our approach can obtain 24.7% energy profit on average, up to 30.5% with a sight boost in performance.

    Drivers eye movement data in simulated construction conflicts at different speeds were collected and analyzed to find the relationship between the drivers' eye movement and the construction conflict. On the basis of the relationship between the drivers' eye movement and the construction conflict, the peak point of wavelet processed pupil diameter, the first point on the left side of the peak point and the first blink point after the peak point are selected as key points for locating construction conflict periods. On the basis of the key points and the GSA, a construction conflict recognition method so called the CCFRM is proposed. And the construction conflict recognition speed and location accuracy of the CCFRM are verified. The good performance of the CCFRM verified the feasibility of proposed key points in construction conflict recognition. Copyright © 2018 Elsevier Ltd. All rights reserved.

  7. [The notion of conflict of interest in the field of health and environment: philosophical and legal approaches].

    Science.gov (United States)

    Hermitte, M-A; Le Coz, P

    2014-06-01

    This paper considers the conflict of interest in philosophical and legal perspective. The philosophical approach comes from two perspectives: political philosophy focuses on the role of the link of interest in the city considered in the light of a broader reflection on the conditions of living together. Antiquity philosophers have enhanced the interest link as privileged vector of humanization and socialization of individuals. In the eighteenth century, Adam Smith considers the pursuit of individual interests a stronger social base that love of neighbor advocated by Christians. Moral philosophy focuses specifically on the passage of interest linked to the conflict of interest. It wondered if we should be impartial in all circumstances or whether it's right to give priority to our friends and loved ones. Thus, it poses the question of whether introspection is sufficient to detect conflicts of interest or if the look of an external third party is still required. The legal process differs from the philosophical approach at two levels; on the one hand, its scope is more limited: the law doesn't envisage the benefits of links of interest on social life even though it may protect some of them (in the context of the family, for example) and is intended to prevent bias that may taint the decision public. On the other hand, the lawyer doesn't enter the interiority of individuals but stands by what appears on the outside: it tracks the suspicion of bias can have serious impacts, such as health and the environment. Somehow, it is more radical. It's noteworthy that despite its many developments, the law can't to stop conflicts of interest in research. Several reasons account for this impasse: scientists receive mission to partner with industry to develop products but they must remain independent in order to assess the risks; there is a tendency to always choose the same experts; there are conflicts of interest intellectuals which are not easy to detect.

    Oil and gas as the non-renewable resources are considered very valuable for the countries with petroleum economics. These resources are not only diffused equally around the world, but also they are common in some places which their neighbors often come into conflicts. Consequently, it is vital for those countries to manage their resource utilization. Lately, game theory was applied in conflict resolution of common resources, such as water, which is a proof of its efficacy and capability. This paper models the conflicts between Iran and its neighbors namely Qatar and Iraq between their oil and gas common resources using game theory approach. In other words, the future of these countries will be introduced and analyzed by some well-known 2 × 2 games to achieve a better perspective of their conflicts. Because of information inadequacy of the players, in addition to Nash Stability, various solution concepts are used based on the foresight, disimprovements, and knowledge of preferences. The results of mathematical models show how the countries could take a reasonable strategy to exploit their common resources.

  11. Gender role conflict and emotional approach coping in men with cancer.

    2009-10-01

    The utility of emotional approach coping (EAC), or expressing and processing emotions, has been equivocal for men. Gender role conflict, or the negative cognitive, emotional and behavioural consequences associated with male gender role socialisation, likely shape coping responses and may negatively affect the efficacy of men's emotion-directed coping efforts and adjustment to cancer. Perceptions of receptiveness of one's interpersonal environment may be particularly important to the effectiveness of EAC. This study examined the relationships among EAC, gender role conflict, and distress in a group of 183 men with cancer. Structural equation modelling revealed that higher gender role conflict was associated with lower emotional expression, which in turn was associated with greater distress. Gender role conflict was not related to emotional processing. Higher gender role conflict also was associated directly with more distress. In subsequent analyses, social constraints and age were examined as possible moderators of EAC. Emotional expression was related to more psychological distress for those in highly constrained environments; and emotional processing was associated with more distress with younger age. Emotional expression may be particularly affected by social influences related to gender and social receptivity. More research is needed to better distinguish constructive and unconstructive emotional processing.

  12. Two distinct emotional experiences in romantic relationships: effects of perceptions regarding approach of intimacy and avoidance of conflict.

    Laurenceau, Jean-Philippe; Troy, Adam B; Carver, Charles S

    2005-08-01

    This study examined how perceived position and velocity regarding approach and avoidance in romantic relationships relate to affective experiences. The authors hypothesized that perceived progress toward intimacy would predict positive affect and that perceived movement toward conflict would predict anxious affect. Ninety-two romantic couples recorded perceived levels of, and perceived changes in, both intimacy and conflict twice daily throughout 10 consecutive days using electronic palm-top devices. Multilevel modeling demonstrated that perceived increase in intimacy related to positive affect above and beyond perceptions of intimacy, conflict, and changes in conflict, for both male and female partners. Perceived increase in conflict related to anxious affect above and beyond perceptions of conflict, intimacy, and changes in intimacy, but only among male partners. Findings support a dual-process view of these feelings in romantic relationships and suggest that increases in positive feelings in close relationships depend on enhancing intimacy rather than on decreasing conflict.

    In conservation process it is unavoidably that conflict incidents may occur among the people and wild-life in the surrounding of the conservation area. Mitigating conflict between wildlife and people is considered a top conservation priority, particularly in landscapes where high densities of people and wildlife co-occur. This conflict is also happened in Leuser conservation area located in the border of North Sumatra and Aceh province, Indonesia. Easing the conflict problem is very difficult. This paper proposes a conceptual model based on system thinking to explore factors that may have great influence on the conflict and to figure out mitigating the conflict. We show how this conceptual framework can be utilized to analyze the conflict occur and further how it could used to develop a multi- criteria decision model.

    2009-01-01

    Trajectory-based operations with self-separation involve the aircraft taking the primary role in the management of its own trajectory in the presence of other traffic. In this role, the flight crew assumes the responsibility for ensuring that the aircraft remains separated from all other aircraft by at least a minimum separation standard. These operations are enabled by cooperative airborne surveillance and by airborne automation systems that provide essential monitoring and decision support functions for the flight crew. An airborne automation system developed and used by NASA for research investigations of required functionality is the Autonomous Operations Planner. It supports the flight crew in managing their trajectory when responsible for self-separation by providing monitoring and decision support functions for both strategic and tactical flight modes. The paper focuses on the latter of these modes by describing a capability for tactical intent-based conflict resolution and its role in a comprehensive suite of automation functions supporting trajectory-based operations with self-separation.

  17. Air traffic surveillance and control using hybrid estimation and protocol-based conflict resolution

    Science.gov (United States)

    Hwang, Inseok

    The continued growth of air travel and recent advances in new technologies for navigation, surveillance, and communication have led to proposals by the Federal Aviation Administration (FAA) to provide reliable and efficient tools to aid Air Traffic Control (ATC) in performing their tasks. In this dissertation, we address four problems frequently encountered in air traffic surveillance and control; multiple target tracking and identity management, conflict detection, conflict resolution, and safety verification. We develop a set of algorithms and tools to aid ATC; These algorithms have the provable properties of safety, computational efficiency, and convergence. Firstly, we develop a multiple-maneuvering-target tracking and identity management algorithm which can keep track of maneuvering aircraft in noisy environments and of their identities. Secondly, we propose a hybrid probabilistic conflict detection algorithm between multiple aircraft which uses flight mode estimates as well as aircraft current state estimates. Our algorithm is based on hybrid models of aircraft, which incorporate both continuous dynamics and discrete mode switching. Thirdly, we develop an algorithm for multiple (greater than two) aircraft conflict avoidance that is based on a closed-form analytic solution and thus provides guarantees of safety. Finally, we consider the problem of safety verification of control laws for safety critical systems, with application to air traffic control systems. We approach safety verification through reachability analysis, which is a computationally expensive problem. We develop an over-approximate method for reachable set computation using polytopic approximation methods and dynamic optimization. These algorithms may be used either in a fully autonomous way, or as supporting tools to increase controllers' situational awareness and to reduce their work load.

    Full Text Available Urban conflicts are a main historiographical field which study has been often conditioned by prejudices and misconceptions that prevented an appropriate knowledge of the development and consequences of their social, political, anthropological and cultural manifestations. In Italian cities, the so-called weigh of the political values from the Ancient world that would have been transferred to the Western civilization, has burdened our perception of the historical reality. Particularly regarding conflicts: an aspect that did not fit the ideal political virtues of the Italian comune. In the Castilian case, the main problem is the excessive political prominence attributed to royal power and its institutional and legal system, an approach that was reinforced in the 80’s when it was linked to the origins of the «Modern State». These perspectives have limited the study of urban conflicts in a complex political society that also managed the control of violence. The article proves that, by putting aside some of the mentioned perspectives, it is possible to achieve new findings regarding conflicts, social behavior in urban history.

    Human-wildlife conflict (HWC) is a conservation concern that increasingly threatens the continued existence of some of the world's most endangered species. With an increase in human population, urban sprawl and subsequent encroachment on wild land, human and wildlife interaction has become inevitable. In the majority of cases, this interaction results in a negative outcome for humans, wildlife or both. In China, these key elements, along with a decrease in wild prey species, have resulted in the expansion of HWC encounters, and the need for alleviating this conflict has become a conservation priority. Loss of human life, livestock and/or crops is most often the catalysts that fuel HWC. Techniques to alleviate conflict around the world have included preventative measures and mitigation techniques, such as financial compensation and other incentive programs. Both types of measures have had variable success. We review the current status of human-carnivore conflict management in China, and, drawing lessons from around the globe, we make recommendations for improving conservation management in China. For example, an increase in law enforcement in nature reserves is vital to reducing human disturbance in prime carnivore habitat, thereby reducing conflict encounters. Also, modifications to current wildlife compensation programs, so that they are linked with preventative measures, will ensure that moral hazards are avoided. Furthermore, investigating the potential for a community self-financed insurance scheme to fund compensation and increasing efforts to restore wild prey populations will improve the outcome for wildlife conservation. Ultimately, HWC management in China will greatly benefit from an integrative approach. © 2012 ISZS, Blackwell Publishing and IOZ/CAS.

  1. Perspective Intercultural Bioethics and Human Rights: the search for instruments for resolving ethical conflicts culturally based.

    2015-10-01

    Full Text Available This article aims to contribute to a deeper reflection on intercultural conflicts within the bioethics scope, and to point out the problem of using human rights as a theoretical normative mediator of the conflicts in bioethics that bear elements of interculturalism. The methodological steps adopted in this inquiry were: analysis of the concept of intercultural conflict in bioethics, from the perception developed by Colectivo Amani; study of human rights as tools of the culture of human beings, based on Bauman’s and Beauchamp’s theories; investigation of the toolsthat human rights offer so as to solve intercultural conflicts in bioethics. It was concluded that intercultural bioethics must incorporate to its prescriptive and descriptive tasks norms and institutions of human rights that ensure the participation and social integration of the individuals from communities that are in cultural conflict. Such measure will act as instrumentsfor the solution of intercultural conflicts.

    Allocating water to organizational stakeholders poses a vital challenge to water managers. Organizations which benefit from water as the primary factor input attempt to achieve their objectives using cost-effective and quick-return strategies, such as increasing the water rights. In such circumstances, lack of water probably results in the conflict. Recognizing the management approaches, organizational priorities, and the stakeholders' influence power can play a dominant role in analyzing the future of such conflicts. In this paper, we analyzed the conflict of water allocation in Ilam dam among organizational stakeholders. We defined the strategies based on the background of the game and organizational objectives. The influence power of stakeholders and the numerical weights of strategies were quantified based on the expert judgment method. The relative priorities of strategies were then calculated for each state of the conflict. We used the GMCR + model to study the actions of stakeholders. Results suggest that the Jihad Agriculture Organization and the Water and Wastewater Company withdraw more water; hence, there exists no water to meet the environmental water right. In this case, the participation of the third party, such as the Governorship and the Justice can change the future of the conflict, and result in moving to the optimal state. However, results from Inverse GMCR analysis demonstrate that Justice is the most influential third party that can move the conflict towards a desired equilibrium (optimal case).

    Hunka, Frantisek; Matula, Jiri

    2017-07-01

    Transaction based approach is utilized in some methodologies in business process modeling. Essential parts of these transactions are human beings. The notion of agent or actor role is usually used for them. The paper on a particular example describes possibilities of Design Engineering Methodology for Organizations (DEMO) and Resource-Event-Agent (REA) methodology. Whereas the DEMO methodology can be regarded as a generic methodology having its foundation in the theory of Enterprise Ontology the REA methodology is regarded as the domain specific methodology and has its origin in accountancy systems. The results of these approaches is that the DEMO methodology captures everything that happens in the reality with a good empirical evidence whereas the REA methodology captures only changes connected with economic events. Economic events represent either change of the property rights to economic resource or consumption or production of economic resources. This results from the essence of economic events and their connection to economic resources.

    Wireless sensor network plays an important role in intelligent navigation. It incorporates a group of sensors to overcome the limitation of single detection system. Dempster-Shafer evidence theory can combine the sensor data of the wireless sensor network by data fusion, which contributes to the improvement of accuracy and reliability of the detection system. However, due to different sources of sensors, there may be conflict among the sensor data under uncertain environment. Thus, this paper proposes a new method combining Deng entropy and evidence distance to address the issue. First, Deng entropy is adopted to measure the uncertain information. Then, evidence distance is applied to measure the conflict degree. The new method can cope with conflict effectually and improve the accuracy and reliability of the detection system. An example is illustrated to show the efficiency of the new method and the result is compared with that of the existing methods.

    Rodent approach-avoidance conflict tests are common preclinical models of human anxiety disorder. Their translational validity mainly rests on the observation that anxiolytic drugs reduce rodent anxiety-like behavior. Here, we capitalized on a recently developed approach-avoidance conflict computer game to investigate the impact of benzodiazepines and of amygdala lesions on putative human anxiety-like behavior. In successive epochs of this game, participants collect monetary tokens on a spatial grid while under threat of virtual predation. In a preregistered, randomized, double-blind, placebo-controlled trial, we tested the effect of a single dose (1 mg) of lorazepam (n = 59). We then compared 2 patients with bilateral amygdala lesions due to Urbach-Wiethe syndrome with age- and gender-matched control participants (n = 17). Based on a previous report, the primary outcome measure was the effect of intra-epoch time (i.e., an adaptation to increasing potential loss) on presence in the safe quadrant of the spatial grid. We hypothesized reduced loss adaptation in this measure under lorazepam and in patients with amygdala lesions. Lorazepam and amygdala lesions reduced loss adaptation in the primary outcome measure. We found similar results in several secondary outcome measures. The relative reduction of anxiety-like behavior in patients with amygdala lesions was qualitatively and quantitatively indistinguishable from an impact of anterior hippocampus lesions found in a previous report. Our results establish the translational validity of human approach-avoidance conflict tests in terms of anxiolytic drug action. We identified the amygdala, in addition to the hippocampus, as a critical structure in human anxiety-like behavior. Copyright © 2017 Society of Biological Psychiatry. Published by Elsevier Inc.

  8. A strategic approach for managing conflict in hospitals: responding to the Joint Commission leadership standard, Part 2.

    Science.gov (United States)

    Scott, Charity; Gerardi, Debra

    2011-02-01

    A well-designed conflict management process for hospital leaders should both retain the positive benefits of constructive conflict engagement and minimize the adverse consequences that unmanaged conflict can have on patient care. Dispute system design (DSD) experts recommend processes that emphasize the identification of the disputing parties' interests and that avoid reliance on exertions of power or resort to rights. In an emerging trend in designing conflict management systems, focus is placed on the relational dynamics among those involved in the conflict, in recognition of the reciprocal impact that each participant in a conflict has on the other. The aim is then to restore trust and heal damaged relationships as a component of resolution. The intent of Standard LD.02.04.01 is to prevent escalation to formal legal disputes and encourage leaders to overcome their conflict-avoidance tendencies through the use of well-designed approaches that support engagement with conflict. The sequence of collaborative options consists of individual coaching and counseling; informal face-to-face meetings; informal, internally facilitated meetings; informal, externally facilitated meetings; formal mediation; and postdispute analysis and feedback. Every hospital has unique needs, and every conflict management process must be tailored to individual circumstances. The recommendations in this two-part article can be adapted and incorporated in other, more comprehensive conflict management processes throughout the hospital. Expanding the conflict competence of leaders to enable them to effectively engage in and model constructive conflict-handling behaviors will further support the strategic goal of providing safe and effective patient care.

    Orientation: Work and family conflicts continuously and negatively affect employees’ performance. Previous research has mostly studied the impact of the two distinct dimensions of work–family conflict (WFC) and family–work conflict (FWC) on health outcomes, whereas the impact of more specific dimensions of these two general types of conflict on health outcomes is little known. Therefore, we now need to also measure the impact of more specified types of these conflicts on health outcomes. ...

  10. Resolving public conflict in site selection process - a risk communication approach

    International Nuclear Information System (INIS)

    Ishizaka, Kaoru; Tanaka, Masaru

    2003-01-01

    In Japan, conflicts regarding the siting of waste disposal facilities occur frequently. In particular, siting of incinerators and landfills has become increasingly difficult because the public is highly concerned about the dioxin issues. Inefficient siting of waste disposal facilities causes several social problems, such as the shortage of waste treatment and disposal facilities, the rising of waste management costs and an increase in the consumption of resources. While dealing with a similar situation, the Chemical Society of Japan adopted a risk communication technique successfully. Hence, the pragmatic use of a risk communication technique is proposed to avoid conflicts and for a smooth information exchange to seek cooperation in waste management. In order to achieve this, a study was conducted to resolve conflicts between residents and the municipality for the selection of site for a solid waste treatment and disposal facility. This study aims to discuss the subject of risk communication for the waste disposal system in Japan. This study is performed through personal interviews and a questionnaire covering opposing parties in the town. As a result of the survey, a risk communication approach for a waste treatment and disposal system is presented in the paper addressing issues such as building of social trust, pragmatic use of the communication process, installation of credible information sources, and environmental education and awareness

  11. An exploration of Bureau of Reclamation approaches for managing conflict over diverging science

    Science.gov (United States)

    Burkardt, Nina; Ruell, Emily; Clark, Douglas

    2008-01-01

    As a major institutional agent supplying Western water resources, the Bureau of Reclamation (Reclamation) provides important leadership, technical, and financial resources in water management, serving as the West's "water broker" (Bowersox 2000; Pisani 2003). In recent years, growing numbers of constituencies using water and the over-allocation of water resources have contributed to conflict over the resource in the American West (National Research Council 2004). Although the conflicts arise from many sources, one common theme is that Reclamation managers often must make decisions about water use and allocation when scientific studies provide uncertain or competing recommendations. We conducted a preliminary study of Reclamation water managers and water scientists to try to understand the approaches or techniques they use or consider useful for dealing with scientific conflicts over water allocation and how these compare to techniques found in the relevant literature. We report the results of (1) an electronic survey of Reclamation senior managers and (2) a panel discussion amongst Reclamation senior managers as to the current institutional capabilities for managing diverging scientific findings in water dispute resolution processes. We conclude with a discussion of the strengths and weaknesses of the different tools and techniques managers reported in the survey and in the panel discussion.

    2003-08-01

    Including children with emotional and behavioral needs in mainstream school systems leads to growing concern about the increasing number of violent and nonviolent conflicts. Schools must adapt to this evolution and adopt a more therapeutic dimension. This paper explores the possibility of integrating school-based and therapeutic conflict management models and compares two management models: a school-based conflict management program. Teaching Students To Be Peacemakers; and a therapeutic conflict management program, Life Space Crisis Intervention. The authors conclude that integration might be possible, but depends on establishing a positive school atmosphere, the central position of the teacher, and collaborative and social learning for pupils. Further implementation of integrated conflict management models can be considered but must be underpinned by appropriate scientific research.

    This article examines four contemporary treatments of the problem of organizational conflict: social psychological, anthropological, neo-Darwinian, and neo-Machiavellian. Social psychological treatments of organizational conflict focus on the dyadic relationship between individual disputants....... In contrast, anthropological treatments take a more socially and historically embedded approach to organizational conflict, focusing on how organizational actors establish negotiated orders of understanding. In a break with the social psychological and anthropological approaches, neo-Darwinians explain...... of organizational conflict where members of an organization are seen as politicized actors engaged in power struggles that continually ebb and flow....

  15. Traffic conflict assessment for non-lane-based movements of motorcycles under congested conditions

    Directory of Open Access Journals (Sweden)

    Long Xuan Nguyen

    2014-03-01

    Full Text Available Traffic conflict under congested conditions is one of the main safety issues of motorcycle traffic in developing countries. Unlike cars, motorcycles often display non-lane-based movements such as swerving or oblique following of a lead vehicle when traffic becomes congested. Very few studies have quantitatively evaluated the effects of such non-lane-based movements on traffic conflict. Therefore, in this study we aim to develop an integrated model to assess the traffic conflict of motorcycles under congested conditions. The proposed model includes a concept of safety space to describe the non-lane-based movements unique to motorcycles, new features developed for traffic conflict assessment such as parameters of acceleration and deceleration, and the conditions for choosing a lead vehicle. Calibration data were extracted from video clips taken at two road segments in Ho Chi Minh City. A simulation based on the model was developed to verify the dynamic non-lane-based movements of motorcycles. Subsequently, the assessment of traffic conflict was validated by calculating the probability of sudden braking at each time interval according to the change in the density of motorcycle flow. Our findings underscore the fact that higher flow density may lead to conflicts associated with a greater probability of sudden breaking. Three types of motorcycle traffic conflicts were confirmed, and the proportions of each type were calculated and discussed.

  16. Development and initial validation of a cognitive-based work-nonwork conflict scale.

    Science.gov (United States)

    Ezzedeen, Souha R; Swiercz, Paul M

    2007-06-01

    Current research related to work and life outside work specifies three types of work-nonwork conflict: time, strain, and behavior-based. Overlooked in these models is a cognitive-based type of conflict whereby individuals experience work-nonwork conflict from cognitive preoccupation with work. Four studies on six different groups (N=549) were undertaken to develop and validate an initial measure of this construct. Structural equation modeling confirmed a two-factor, nine-item scale. Hypotheses regarding cognitive-based conflict's relationship with life satisfaction, work involvement, work-nonwork conflict, and work hours were supported. The relationship with knowledge work was partially supported in that only the cognitive dimension of cognitive-based conflict was related to extent of knowledge work. Hypotheses regarding cognitive-based conflict's relationship with family demands were rejected in that the cognitive dimension correlated positively rather than negatively with number of dependent children and perceived family demands. The study provides encouraging preliminary evidence of scale validity.

    The high prevalence of gender-based violence (GBV) in armed conflict has been documented in various national contexts, but less is known about the complex pathways that constitute the relation between the two. Employing a community-based collaborative approach, we constructed a community-informed socioecological conceptual model from a feminist perspective, detailing how armed conflict relates to GBV in a conflict-affected rural community in Northeastern Uganda. The research questions were as follows: (1) How does the community conceptualize GBV? and (2) How does armed conflict relate to GBV? Nine focus group discussions divided by gender, age, and profession and six key informant interviews were conducted. Participants’ ages ranged from 9 to 80 years (n =34 girls/women, n = 43 boys/men). Grounded theory was used in analysis. Participants conceptualized eight forms of and 22 interactive variables that contributed to GBV. Armed conflict affected physical violence/quarreling, sexual violence, early marriage, and land grabbing via a direct pathway and four indirect pathways initiated through looting of resources, militarization of the community, death of a parent(s) or husband, and sexual violence. The findings suggest that community, organizational, and policy-level interventions, which include attention to intersecting vulnerabilities for exposure to GBV in conflict-affected settings, should be prioritized. While tertiary psychological interventions with women and girls affected by GBV in these areas should not be eliminated, we suggest that policy makers and members of community and organizational efforts make systemic and structural changes.

    2017-01-01

    The risks and conflicts of the fossil-nuclear age are in contrast to the effects of renewable energies which appear in a largely positive light. However, the transformation towards a low-carbon energy supply creates new energy landscapes with a high demand for suitable land areas - which may also provoke energy conflicts. Technology assessment can contribute to reducing such energy conflicts and increasing public acceptance by using spatial agent-based models that represent dynamic decisions and interactions of stakeholders regarding energy alternatives and land-use options. Northern Germany serves as a case study region where farmers and communities are local actors of the energy transition.

    2016-12-01

    Full Text Available As a part of a larger research project on complex linkages between security and development implemented by the Center for Security and Development Studies at the Lomonosov Moscow State University, this paper examines the complex dilemmas of pursuing comprehensive approach to post-conflict reconstruction with an example of Federal Republic of Germany’s experience with the Provincial Reconstruction Teams (PRTs in Afghanistan after the terrorist attacks of 9/11. The first section depicts the background of deployment of the PRTs on Afghan territory. The second section compares the U.S., British and German models of PRTs and assesses the role of those teams as vehicles of close civil-military, interagency coordination. The third and the fourth sections identify respectively characteristic features of the German PRTs’ activities in Kunduz and Badakhshan provinces and the main obstacles that hindered the achievement of key objectives. The conclusion contains a concise assessment of effectiveness and efficiency of PRTs as a mechanism of addressing complex challenges of post-conflict reconstruction and transition to peaceful development. It also postulates that the PRT model, regardless of some objective difficulties faced by various German agencies, may be very relevant in the future in fulfilling a revised agenda of the German foreign and defense policies in the XXI century.

  3. Divided parents, shared children
    Conflicting approaches to relocation disputes in the USA

    Directory of Open Access Journals (Sweden)

    Theresa Glennon

    2008-06-01

    Full Text Available Custody relocation disputes pose intractable dilemmas for courts in a highly mobile society. The custodial parent, most often a woman, seeks self-determination, freedom of movement and a continued custodial relationship with the child. The non-custodial parent seeks to preserve a geographically close relationship with the child. Courts must identify the best interests of the children amidst these multiple and conflicting interests. They make decisions that may determine the course of custodial parents’ lives, affecting remarriage, employment, education, and proximity to family. A narrow doctrinal focus on children’s best interests ignores these key aspects of relocation disputes. This article examines the varied legislative and judicial approaches to relocation disputes in the US and proposed principles for resolution of these disputes. It reviews scholarship analyzing relocation disputes from a wide range of perspectives, including: conflicting social science research; competing ideologies of the post-divorce family; alternative dispute resolution; parents’ constitutional rights; domestic violence victims; and proposals to eliminate geographic presumptions and remedy the economic effect of restraints on relocation. Relocation doctrine in the US should be realigned to address these complex perspectives. States should also assist post-divorce families to support children through the common experience of relocation.

  6. Landscapes with different logics: A physicalistic approach to semantic conflicts in spatial planning

    Directory of Open Access Journals (Sweden)

    Krzysztofik Robert

    2017-12-01

    Full Text Available This paper deals with the ways of categorising landscapes as ‘urban’ and ‘rural’ using a physicalist approach, where these terms have special meaning. The aim of this paper is to elaborate on the question whether such a division is still meaningful with regard to anthropogenic landscapes, not least in spatial planning. The concerns raised in this paper depart from the increasingly complicated structure of geographical space, including that of anthropogenic landscapes. Our standpoint is illustrated using cases of landscape ambiguities from Poland, Germany, Romania and Greece. Leaning on frameworks of physicalist (mechanicistic theory, this paper suggests an explanation to the outlined semantic conflicts. This is done by pointing to the relationality between the impact of centripetal and centrifugal forces, the specifics of socio-economic development, as well as the varying landscape forms that emerge from the differences within that development.

  7. Two Monthly Continuous Dynamic Model Based on Nash Bargaining Theory for Conflict Resolution in Reservoir System.

    So far many optimization models based on Nash Bargaining Theory associated with reservoir operation have been developed. Most of them have aimed to provide practical and efficient solutions for water allocation in order to alleviate conflicts among water users. These models can be discussed from two viewpoints: (i) having a discrete nature; and (ii) working on an annual basis. Although discrete dynamic game models provide appropriate reservoir operator policies, their discretization of variables increases the run time and causes dimensionality problems. In this study, two monthly based non-discrete optimization models based on the Nash Bargaining Solution are developed for a reservoir system. In the first model, based on constrained state formulation, the first and second moments (mean and variance) of the state variable (water level in the reservoir) is calculated. Using moment equations as the constraint, the long-term utility of the reservoir manager and water users are optimized. The second model is a dynamic approach structured based on continuous state Markov decision models. The corresponding solution based on the collocation method is structured for a reservoir system. In this model, the reward function is defined based on the Nash Bargaining Solution. Indeed, it is used to yield equilibrium in every proper sub-game, thereby satisfying the Markov perfect equilibrium. Both approaches are applicable for water allocation in arid and semi-arid regions. A case study was carried out at the Zayandeh-Rud river basin located in central Iran to identify the effectiveness of the presented methods. The results are compared with the results of an annual form of dynamic game, a classical stochastic dynamic programming model (e.g. Bayesian Stochastic Dynamic Programming model, BSDP), and a discrete stochastic dynamic game model (PSDNG). By comparing the results of alternative methods, it is shown that both models are capable of tackling conflict issues in water allocation

    Full Text Available This paper explores the effect of diversity and conflict management on the relationship between teamwork and organizational outcomes of small technology-based firms. To study the relationship between those variables, a quantitative research was conducted. The results of the survey involving 107 small Brazilian high-tech firms show that diversity and conflict management positively moderate the relationship between teamwork and organizational outcomes. So that, at higher levels of diversity and conflict management, best organizational outcomes. At the same time, it has been verified that conflict management is important regardless the level of diversity within teams. This research sheds new light on the factors that should be considered to become teamwork more effective in this specific context.

  10. Conflict Management in Participatory Approaches to Water Management: A Case Study of Lake Ontario and the St. Lawrence River Regulation

    2016-07-01

    Full Text Available The International Joint Commission (IJC has been involved in a 14-year effort to formulate a new water regulation plan for the Lake Ontario St. Lawrence River (“LOSLR” area that balances the interests of a diverse group of stakeholders including shipping and navigation, hydropower, environment, recreational boating, municipal and domestic water supply, First Nations, and shoreline property owners. It has embraced the principles of collaborative and participatory management and, applying a Shared Visioning Planning (SVP approach, has worked closely with stakeholders throughout all stages of this process; however, conflicts between competing stakeholders have delayed and complicated this effort. The overarching aim of this paper is to consider the extent to which the SVP approach employed by the IJC was effective in managing conflict in the LOSLR context. Audio recordings and transcriptions of public and technical hearings held by the IJC in 2013 have been systematically analysed using stakeholder mapping and content analysis methods, to gain insight into the stakeholder universe interacting with the IJC on Plan 2014.  The principal conclusions of this paper are that (a the Shared Vision Planning approach employed by the IJC had some significant successes in terms of conflict management—particularly notable is the success that has been achieved with regards to integration of First Nation concerns; (b there is a distinct group of shoreline property owners, based in New York State, who remain opposed to Plan 2014—the IJC’s public outreach and participation efforts have not been successful in reconciling their position with that of other stakeholders due to the fact that this stakeholder group perceive that they can only lose out from any regulation change and are therefore unlikely to be motivated to engage productively in any planning dialogue; and (c a solution would require that the problem be reframed so that this stakeholder can see

    Successful emotion regulation is a fundamental prerequisite for well-being and dysregulation may lead to psychopathology. The ability to inhibit spontaneous emotions while behaving in accordance with desired goals is an important dimension of emotion regulation and can be measured using emotional conflict resolution tasks. Few studies have investigated the gray matter correlates underlying successful emotional conflict resolution at the whole-brain level. We had 190 adults complete an emotional conflict resolution task (face-word task) and examined the brain regions significantly correlated with successful emotional conflict resolution using voxel-based morphometry. We found successful emotional conflict resolution was associated with increased regional gray matter density in widely distributed brain regions. These regions included the dorsal anterior cingulate/dorsal medial prefrontal cortex, ventral medial prefrontal cortex, supplementary motor area, amygdala, ventral striatum, precuneus, posterior cingulate cortex, inferior parietal lobule, superior temporal gyrus and fusiform face area. Together, our results indicate that individual differences in emotional conflict resolution ability may be attributed to regional structural differences across widely distributed brain regions.

  13. When conflicts are good: nonconscious goal conflicts reduce confirmatory thinking.

    Science.gov (United States)

    Kleiman, Tali; Hassin, Ran R

    2013-09-01

    In this article, we argue that nonconscious goal conflicts are accompanied by a mindset that has wide-ranging implications for reasoning and thinking in content areas that are not part of the conflict itself. Specifically, we propose that nonconscious goal conflicts induce a mode of processing information that increases the likelihood of approaching an issue from opposing perspectives. This hypothesis is examined by investigating the effects of nonconscious goal conflicts on confirmatory thinking, that is, a way of thinking that narrowly focuses on confirmation rather than on broader examination of information. In 5 experiments, we show that nonconscious goal conflicts significantly reduce confirmatory hypothesis testing (Experiments 1 through 3) and anchoring (Experiments 4 and 5). We further show that these effects result from a goal conflict by rejecting explanations based on priming of semantic opposites, and priming of multiple goals that do not conflict (Experiments 2 and 3), and by examining decision times as a conflict process variable (Experiment 5). Using various probes, we show that these changes in confirmatory judgments are not accompanied by changes in conflict phenomenology. Together, these results suggest that nonconscious goal conflicts attenuate the robust confirmatory thinking strategy that characterizes human thinking in numerous domains.

    Previous works on the effect of self-construal in interpersonal behaviours tend to adopt a main effect approach. The present research proposes an interactive approach in understanding two response patterns in dyadic conflict by combining self-construal and the stance of the opponent. Independent self-construal was hypothesised to be associated with a self-centred pattern of conflict response, which is characterised by taking contending responses regardless of whether the stance of the opponent is dominant or submissive. Relational self-construal was hypothesised to be associated with a tuning-in pattern of conflict response, which is characterised by showing contending responses when the opponent is submissive but yielding responses when the opponent is dominant. With trait self-construal measured and opponent's stance manipulated, Study 1 provided initial support for the hypotheses. Study 2 showed a three-way interaction effect between trait self-construal, manipulated self-construal and the opponent's stance on actual conflict responses during discussion of a scenario. The effect of self-construal manipulation was only observed among people who were low in trait independent self-construal and average in trait relational self-construal. The results pinpoint the importance of considering personal and opponent factors simultaneously in understanding the dynamics of dyadic conflict processes. © 2015 International Union of Psychological Science.

    Full Text Available Food stimuli are omnipresent and naturally primary reinforcing stimuli. One explanation for the intake of high amounts of food in binge eating disorder (BED is a deviant valuation process. Valuation of food stimuli is supposed to influence approach or avoidance behaviour towards food. Focusing on self-reported and indirect (facial electromyography valuation process, motivational aspects in the processing of food stimuli were investigated.We compared an overweight sample with BED (BED+ with an overweight sample without BED (BED- and with normal weight controls (NWC regarding their self-reported and indirect (via facial electromyography valuation of food versus non-food stimuli.Regarding the self-reported valuation, the BED+ sample showed a significantly stronger food-bias compared to the BED- sample, as food stimuli were rated as significantly more positive than the non-food stimuli in the BED+ sample. This self-reported valuation pattern could not be displayed in the indirect valuation. Food stimuli evoked negative indirect valuation in all groups. The BED+ sample showed the plainest approach-avoidance conflict marked by a diverging self-reported (positive and indirect (negative valuation of food stimuli.BED+ showed a deviant self-reported valuation of food as compared to BED-. The valuation process of the BED+ sample seems to be characterized by a motivational ambivalence. This ambivalence should be subject of further studies and may be of potential use for therapeutic interventions.

    Collaborative design is a new style for modern mechanical design to meet the requirement of increasing competition. Designers of different places complete the same work, but the conflict appears in the process of design which may interface the design. Case-based reasoning (CBR) method is applied to the problem of conflict resolution, which is in the artificial intelligence field. However, due to the uncertainties in knowledge representation, attribute description, and similarity measures of CBR, it is very difficult to find the similar cases from case database. A fuzzy CBR method was proposed to solve the problem of conflict resolution in collaborative design. The process of fuzzy CBR was introduced. Based on the feature attributes and their relative weights determined by a fuzzy technique, a fuzzy CBR retrieving mechanism was developed to retrieve conflict resolution cases that tend to enhance the functions of the database. By indexing, calculating the weight and defuzzicating of the cases, the case similarity can be obtained. Then the case consistency was measured to keep the right result. Finally, the fuzzy CBR method for conflict resolution was demonstrated by means of a case study. The prototype system based on web is developed to illustrate the methodology.

  17. Managing conflicts arising from fisheries enhancements based on non-native fishes in southern Africa.

    Southern Africa has a long history of non-native fish introductions for the enhancement of recreational and commercial fisheries, due to a perceived lack of suitable native species. This has resulted in some important inland fisheries being based on non-native fishes. Regionally, these introductions are predominantly not benign, and non-native fishes are considered one of the main threats to aquatic biodiversity because they affect native biota through predation, competition, habitat alteration, disease transfer and hybridization. To achieve national policy objectives of economic development, food security and poverty eradication, countries are increasingly looking towards inland fisheries as vehicles for development. As a result, conflicts have developed between economic and conservation objectives. In South Africa, as is the case for other invasive biota, the control and management of non-native fishes is included in the National Environmental Management: Biodiversity Act. Implementation measures include import and movement controls and, more recently, non-native fish eradication in conservation priority areas. Management actions are, however, complicated because many non-native fishes are important components in recreational and subsistence fisheries that contribute towards regional economies and food security. In other southern African countries, little attention has focussed on issues and management of non-native fishes, and this is cause for concern. This paper provides an overview of introductions, impacts and fisheries in southern Africa with emphasis on existing and evolving legislation, conflicts, implementation strategies and the sometimes innovative approaches that have been used to prioritize conservation areas and manage non-native fishes. © 2014 The Fisheries Society of the British Isles.

    Dierdorff, Erich C; Ellington, J Kemp

    2008-07-01

    The consequences of work-family conflict for both individuals and organizations have been well documented, and the various sources of such conflict have received substantial attention. However, the vast majority of extant research has focused on only time- and strain-based sources, largely neglecting behavior-based sources. Integrating two nationally representative databases, the authors examine 3 behavior-based antecedents of work-family conflict linked specifically to occupational work role requirements (interdependence, responsibility for others, and interpersonal conflict). Results from multilevel analysis indicate that significant variance in work-family conflict is attributable to the occupation in which someone works. Interdependence and responsibility for others predict work-family conflict, even after controlling for several time- and strain-based sources.

    Mopeds are a popular transportation mode in Europe and Asia. Moped-related traffic accidents account for a large proportion of crash fatalities. To develop moped-related crash countermeasures, it is important to understand the characteristics of moped-related conflicts. Naturalistic driving study data were collected in Shanghai, China from 36 car drivers. The data included 2,878h and 78,296km driven from 13,149 trips. Moped-car conflicts were identified and examined from the passenger car driver's perspective using kinematic trigger algorithms and manual video reduction. A total of 119 moped-car conflicts were identified, including 74 high g-force conflicts and 45 low g-force events. These conflicts were classified into 22 on-road configurations where both similarities and differences were found as compared to Western Countries. The majority of the conflicts occurred on secondary main roads and branch roads. Hard braking was the primary response that the car drivers made to these conflicts rather than hard steering. The identified on-road vehicle-moped conflict configurations in Shanghai, China may be attributed to the complicated traffic environment and risky behavior of moped riders. The lower prevalence of hard steering in Shanghai as compared to the United States may be due to the lower speeds at event onsets or less available steering space, e.g., less available shoulder area on Chinese urban roads. The characteristics of moped-car conflicts may impact the design of active safety countermeasures on passenger cars. The pilot data from Shanghai urban areas suggest that countermeasures developed for China may require some modifications to those developed for the United States and European countries, although this recommendation may not be conclusive given the small sample size of the study. Future studies with large samples may help better understand the characteristics of moped-car conflicts. Copyright © 2017 National Safety Council and Elsevier Ltd. All rights

    The problems that often occur in the learning of physics is a matter of misconception and low understanding of the concept. Misconceptions do not only happen to students, but also happen to college students and teachers. The existing learning model has not had much impact on improving conceptual understanding and remedial efforts of student misconception. This study aims to see the impact of cognitive-based learning model in improving conceptual understanding and remediating student misconceptions. The research method used is Design / Develop Research. The product developed is a cognitive conflict-based learning model along with its components. This article reports on product design results, validity tests, and practicality test. The study resulted in the design of cognitive conflict-based learning model with 4 learning syntaxes, namely (1) preconception activation, (2) presentation of cognitive conflict, (3) discovery of concepts & equations, (4) Reflection. The results of validity tests by some experts on aspects of content, didactic, appearance or language, indicate very valid criteria. Product trial results also show a very practical product to use. Based on pretest and posttest results, cognitive conflict-based learning models have a good impact on improving conceptual understanding and remediating misconceptions, especially in high-ability students.

  5. A transdisciplinary approach to understanding the causes of wicked problems such as the violent conflict in Rwanda

    Full Text Available The paper is presented against a background of many wicked problems that confront us in the world today such as violent crime, conflict that emanates from political power seeking, contests for scarce resources, the increasing reaction all over the world to the deterioration of socio-economic conditions and the devastation caused by natural disasters. This article will argue that the challenge of violent conflict requires an innovative approach to research and problem solving and proposes a research methodology that follows a transdisciplinary approach. The argument is informed by field research during 2006 on the management of knowledge in the Great Lakes region of Africa, including research on how knowledge on the 1994 genocide in Rwanda is managed. The paper will make recommendations on how transdisciplinary research is required to determine the causes of violent conflict in an African context and how practitioners and academics should engage in transdisciplinarity. It was found that trans- disciplinary research is required to gain better insight into the causes of violent conflict in an African context. It requires from the researcher to recognise the many levels of reality that has to be integrated towards a synthesis to reveal new insights into the causes of violent conflict, including recognising the existence of a normative-spiritual realm that informs the epistemology of Africa. It furthermore requires a methodology that allows us to break out of the stifling constraints of systems thinking and linear processes into the inner space at the juncture where disciplines meet (the diversity of African communities.

  6. Fast Conflict Resolution Based on Reinforcement Learning in Multi-agent System

    PIAOSonghao; HONGBingrong; CHUHaitao

    2004-01-01

    In multi-agent system where each agen thas a different goal (even the team of agents has the same goal), agents must be able to resolve conflicts arising in the process of achieving their goal. Many researchers presented methods for conflict resolution, e.g., Reinforcement learning (RL), but the conventional RL requires a large computation cost because every agent must learn, at the same time the overlap of actions selected by each agent results in local conflict. Therefore in this paper, we propose a novel method to solve these problems. In order to deal with the conflict within the multi-agent system, the concept of potential field function based Action selection priority level (ASPL) is brought forward. In this method, all kinds of environment factor that may have influence on the priority are effectively computed with the potential field function. So the priority to access the local resource can be decided rapidly. By avoiding the complex coordination mechanism used in general multi-agent system, the conflict in multi-agent system is settled more efficiently. Our system consists of RL with ASPL module and generalized rules module. Using ASPL, RL module chooses a proper cooperative behavior, and generalized rule module can accelerate the learning process. By applying the proposed method to Robot Soccer, the learning process can be accelerated. The results of simulation and real experiments indicate the effectiveness of the method.

    2010-01-01

    The information provided by global positioning systems is never totally exact, and there are always errors when measuring position and velocity of moving objects such as aircraft. This paper studies the effects of these errors in the actual separation of aircraft in the context of state-based conflict detection and resolution. Assuming that the state information is uncertain but that bounds on the errors are known, this paper provides an analytical definition of a safety buffer and sufficient conditions under which this buffer guarantees that actual conflicts are detected and solved. The results are presented as theorems, which were formally proven using a mechanical theorem prover.

    International Nuclear Information System (INIS)

    Alesso, H.P.

    1981-01-01

    We describe one design for a microprocessor-based, on-line decision aid for identifying and resolving false, conflicting, or misleading instrument indications resulting from certain systems interactions for a pressurized water reactor. The system processes sensor signals from groups of instruments that track together under nominal transient and certain accident conditions, and alarms when they do not track together. We examine multiple-casualty systems interaction and formulate a trial grouping of variables that track together under specified conditions. A two-of-three type redundancy check of key variables provides alarm and indication of conflicting information when one signal suddenly tracks in opposition due to multiple casualty, instrument failure, and/or locally abnormal conditions. Since a vote count of two of three variables in conflict as inconclusive evidence, the system is not designed to provide tripping or corrective action, but improves the operator/instrument interface by providing additional and partially digested information

    2013-07-01

    Work-family conflict, a prevalent stressor in today's workforce, has been linked to several detrimental consequences for the individual, including physical health. The present study extends this area of research by examining episodic work-family conflict in relation to objectively measured cardiovascular health indicators (systolic and diastolic blood pressure and heart rate) using an experience sampling methodology. The results suggested that the occurrence of an episode of work interference with family conflict is linked to a subsequent increase in heart rate but not blood pressure; however, the relationship between episodes of family interference with work conflict and both systolic and diastolic blood pressure is moderated by perceptions of family-supportive supervision. No evidence was found for the moderating role of work-supportive family. Further theoretical and practical implications are discussed. PsycINFO Database Record (c) 2013 APA, all rights reserved.

    The aim of this study was to clarify the relationship between social support, decisional conflict, and attitude towards advance directives, and determine whether decisional conflict mediates the relation between social support and advance directives attitude among older adults in South Korea. In total, 209 community-based older adults (mean age, 74.82 years) participated in this cross-sectional study. Demographic characteristics, self-perceived health status, social support, decisional conflict, and advance directives attitude were investigated via a structured questionnaire. Data analysis was carried out using Pearson's correlation and path analyses. The mean score of advance directives attitude was 48.01 (range, 35-61). Decisional conflict and social support were both significantly related to advance directives attitude (P conflict was a mediator between social support and advance directives attitudes. The results confirmed the importance of social support for reducing decisional conflict and encouraging positive attitudes toward advance directives.

  18. Paper Fish and Policy Conflict: Catch Shares and Ecosystem-Based Management in Maine's Groundfishery

    Directory of Open Access Journals (Sweden)

    Jennifer F. Brewer

    2011-03-01

    Full Text Available The National Oceanic and Atmospheric Administration professes support for ecosystem-based fisheries management, as mandated by Congress in the Fishery Conservation and Management Act, and as endorsed by the Obama Administration's national ocean policy. Nonetheless, driving agency policies, including catch shares and fishing quotas, focus principally on individual species, diverting attention from ecosystem considerations such as habitat, migratory patterns, trophic relationships, fishing gear, and firm-level decision making. Environmental non-governmental organization (ENGO agendas manifest similar inconsistencies. A case study of Maine's groundfishery demonstrates implications of this policy conflict at the local level. There, multigenerational fishing villages have historically pursued diversified and adaptive livelihood strategies, supported by local ecological knowledge. This tradition is increasingly eroded by regulatory constraints, including catch shares. Field observation, interviews, survey data, and archival review reveal that industry-supported, ecosystem-focused proposals have been rejected by the New England Fishery Management Council, despite the apparent failure of single-species approaches to sustain fish populations, fished ecosystems, and fishing-dependent communities. The creation of groundfishery catch share sectors is likely to perpetuate industry consolidation and political entrenchment under more mobile capital, following precedent set by days-at-sea, and making area protections and gear restrictions less likely. Pending marine spatial planning efforts could enhance social-ecological resilience by creating new opportunities for transdisciplinary decision support, and broader public participation and accountability.

    Galashan, Daniela; Wittfoth, Matthias; Fehr, Thorsten; Herrmann, Manfred

    2008-07-01

    Behavioral and electrophysiological correlates of two Simon tasks were examined using comparable stimuli but different task-irrelevant and conflict-inducing stimulus features. Whereas target shape was always the task-relevant stimulus attribute, either target location (location-based task) or motion direction within the target stimuli (motion-based task) was used as a source of conflict. Data from ten healthy participants who performed both tasks are presented. In the motion-based task the incompatible condition showed smaller P300 amplitudes at Pz than the compatible condition and the location-based task yielded a trend towards a reduced P300 amplitude in the incompatible condition. For both tasks, no P300 latency differences between the conditions were found at Pz. The results suggest that the motion-based task elicits behavioral and electrophysiological effects comparable with regular Simon tasks. As all stimuli in the motion-based Simon task were presented centrally the present data strongly argue against the attention-shifting account as an explanatory approach.

    This meta-analysis of 64 studies (5,071 couples) used a metacoding system to categorize observed couple conflict behaviors into categories differing in terms of valence (positive to negative) and intensity (high to low) and resulting in five behavioral categories: hostility, distress, withdrawal, problem solving, and intimacy. Aggregate effect sizes indicated that women were somewhat more likely to display hostility, distress, and intimacy during conflict, whereas men were somewhat more likely to display withdrawal and problem solving. Gender differences were of a small magnitude. For both men and women, hostility was robustly associated with lower relationship satisfaction (medium effect), distress and withdrawal were somewhat associated (small effect), and intimacy and problem solving were both closely associated with relationship satisfaction (medium effect). Effect sizes were moderated in several cases by study characteristics including year of publication, developmental period of the sample, recruitment design, duration of observed conflict, method used to induce conflict, and type of coding system used. Findings from this meta-analysis suggest that high-intensity conflict behaviors of both a positive and negative nature are important correlates of relationship satisfaction and underscore the relatively small gender differences in many conflict behaviors. 2011 APA, all rights reserved

  1. Nuclear waste repository siting and locational conflict analysis: A contextual approach

    International Nuclear Information System (INIS)

    Murauskas, G.T.

    1989-01-01

    This study develops and evaluates an alternative framework that is based on contextual variables. The premise is that differences in attitudes and perceptions regarding the local siting of nuclear wastes and differences in attitudes regarding siting decision-making procedures are influenced by local political, economic, and cultural variables. This framework articulates the nature of conflict in terms of the incongruence between the use-value individuals ascribe to their present situation and the anticipated exchange-value individuals associate with the local siting of a nuclear waste repository. In order to evaluate this conceptual framework a survey was conducted of residents in four communities representing distinct societal contexts: Richton, Mississippi; Peterborough, New Hampshire; Richland, Washington; and Antigo/Waupaca, Wisconsin. Data analyses indicate substantial differences in economic expectations associated with the local siting of a high-level nuclear waste repository and in perception regarding the impacts such a repository might have on the environment, local agriculture, personal health and safety, and the quality of life

    Cognitive control allows humans to direct and coordinate their thoughts and actions in a flexible way, in order to reach internal goals regardless of interference and distraction. The hallmark test used to examine cognitive control is the Stroop task, which elicits both the weakly learned but goal-relevant and the strongly learned but goal-irrelevant response tendencies, and requires people to follow the former while ignoring the latter. After reviewing the existing computational models of cognitive control in the Stroop task, its novel, integrated utility-based model is proposed. The model uses 3 crucial control mechanisms: response utility reinforcement learning, utility-based conflict evaluation using the Festinger formula for assessing the conflict level, and top-down adaptation of response utility in service of conflict resolution. Their complex, dynamic interaction led to replication of 18 experimental effects, being the largest data set explained to date by 1 Stroop model. The simulations cover the basic congruency effects (including the response latency distributions), performance dynamics and adaptation (including EEG indices of conflict), as well as the effects resulting from manipulations applied to stimulation and responding, which are yielded by the extant Stroop literature.

    Categorical perception (CP) of color manifests as faster or more accurate discrimination of two shades of color that straddle a category boundary (e.g., one blue and one green) than of two shades from within the same category (e.g., two different shades of green), even when the differences between the pairs of colors are equated according to some objective metric. The results of two experiments provide new evidence for a conflict-based account of this effect, in which CP is caused by competition between visual and verbal/categorical codes on within-category trials. According to this view, conflict arises because the verbal code indicates that the two colors are the same, whereas the visual code indicates that they are different. In Experiment 1, two shades from the same color category were discriminated significantly faster when the previous trial also comprised a pair of within-category colors than when the previous trial comprised a pair from two different color categories. Under the former circumstances, the CP effect disappeared. According to the conflict-based model, response conflict between visual and categorical codes during discrimination of within-category pairs produced an adjustment of cognitive control that reduced the weight given to the categorical code relative to the visual code on the subsequent trial. Consequently, responses on within-category trials were facilitated, and CP effects were reduced. The effectiveness of this conflict-based account was evaluated in comparison with an alternative view that CP reflects temporary warping of perceptual space at the boundaries between color categories.

  4. Why mutual helping in most natural systems is neither conflict-free nor based on maximal conflict.

    Mutual helping for direct benefits can be explained by various game theoretical models, which differ mainly in terms of the underlying conflict of interest between two partners. Conflict is minimal if helping is self-serving and the partner benefits as a by-product. In contrast, conflict is maximal if partners are in a prisoner's dilemma with both having the pay-off-dominant option of not returning the other's investment. Here, we provide evolutionary and ecological arguments for why these two extremes are often unstable under natural conditions and propose that interactions with intermediate levels of conflict are frequent evolutionary endpoints. We argue that by-product helping is prone to becoming an asymmetric investment game since even small variation in by-product benefits will lead to the evolution of partner choice, leading to investments by the chosen class. Second, iterated prisoner's dilemmas tend to take place in stable social groups where the fitness of partners is interdependent, with the effect that a certain level of helping is self-serving. In sum, intermediate levels of mutual helping are expected in nature, while efficient partner monitoring may allow reaching higher levels. © 2016 The Author(s).

  5. Considerations Regarding the Conflict Management

    Full Text Available The conflict has always been present among people. It arises at the level of human relationships and has a specific form of expression, according to its evolutionary stage. Because of the fact that people are part of an organization, they bring the conflict with themselves. Any attempt of efficiently managing an organization without taking into account the fact that organizational conflicts are inevitable are bound to failure. In order to successfully handle conflicting situations, old habits and empirical pieces of knowledge are no longer sufficient. We therefore witness the birth of new theoretical concepts and innovative practices, as well as the coming into being of different strategies and approaches re garding conflict management which are based on a set of clear ideas that we will develop in the following article.

    Conservation conflicts are increasing and need to be managed to minimise negative impacts on biodiversity, human livelihoods, and human well-being. Here, we explore strategies and case studies that highlight the long-term, dynamic nature of conflicts and the challenges to their management. Conflict management requires parties to recognise problems as shared ones, and engage with clear goals, a transparent evidence base, and an awareness of trade-offs. We hypothesise that conservation outcomes will be less durable when conservationists assert their interests to the detriment of others. Effective conflict management and long-term conservation benefit will be enhanced by better integration of the underpinning social context with the material impacts and evaluation of the efficacy of alternative conflict management approaches.

    2016-09-01

    Full Text Available In this article, a tree search algorithm is proposed to find the near optimal conflict avoidance solutions for unmanned aerial vehicles. In the dynamic environment, the unmodeled elements, such as wind, would make UAVs deviate from nominal traces. It brings about difficulties for conflict detection and resolution. The back propagation neural networks are utilized to approximate the unmodeled dynamics of the environment. To satisfy the online planning requirement, the search length of the tree search algorithm would be limited. Therefore, the algorithm may not be able to reach the goal states in search process. The midterm reward function for assessing each node is devised, with consideration given to two factors, namely, the safe separation requirement and the mission of each unmanned aerial vehicle. The simulation examples and the comparisons with previous approaches are provided to illustrate the smooth and convincing behaviours of the proposed algorithm.

  9. Navigational Traffic Conflict Technique: A Proactive Approach to Quantitative Measurement of Collision Risks in Port Waters

    Debnath, Ashim Kumar; Chin, Hoong Chor

    Navigational safety analysis relying on collision statistics is often hampered because of the low number of observations. A promising alternative approach that overcomes this problem is proposed in this paper. By analyzing critical vessel interactions this approach proactively measures collision risk in port waters. The proposed method is illustrated for quantitative measurement of collision risks in Singapore port fairways, and validated by examining correlations between the measured risks with those perceived by pilots. This method is an ethically appealing alternative to the collision-based analysis for fast, reliable and effective safety assessment, thus possessing great potential for managing collision risks in port waters.

    The three constructs of work-family conflict, emotional exhaustion and performance-based self-esteem are all related to tremendous negative consequences for the individual, the organization as well as for society. Even though there are studies that connect two of those constructs, the prospective relations between all three of them have not been studied yet. We explored the prospective relations between the three constructs in a large Swedish data set representative of the Swedish workforce. Gender differences in the relations were investigated. Longitudinal data with a 2-year time lag were gathered from 3,387 working men and women who responded to the 2006 and 2008 waves of the Swedish Longitudinal Occupational Survey of Health. Four different cross-lagged models were analysed. In the best fitting model, higher levels of work-family conflict at time 1 were associated with an increased level of performance-based self-esteem at time 2, but not with emotional exhaustion, after controlling for having children, gender, education and age. Also, relationships between emotional exhaustion at time 1 and work-family conflict and performance-based self-esteem at time 2 could be established. Furthermore, relationships between performance-based self-esteem time 1 and work-family conflict and emotional exhaustion time 2 were found. Multiple-group analysis did not show any differences in the relations of the tested constructs over time for either men or women. We conclude that the three constructs are interrelated and best understood through a reciprocal model. No differences were found between men and women.

  16. Toll-Like Receptor 4 Deficiency Causes Reduced Exploratory Behavior in Mice Under Approach-Avoidance Conflict.

    Abnormal approach-avoidance behavior has been linked to deficits in the mesolimbic dopamine (DA) system of the brain. Recently, increasing evidence has indicated that toll-like receptor 4 (TLR4), an important pattern-recognition receptor in the innate immune system, can be directly activated by substances of abuse, resulting in an increase of the extracellular DA level in the nucleus accumbens. We thus hypothesized that TLR4-dependent signaling might regulate approach-avoidance behavior. To test this hypothesis, we compared the novelty-seeking and social interaction behaviors of TLR4-deficient (TLR4(-/-)) and wild-type (WT) mice in an approach-avoidance conflict situation in which the positive motivation to explore a novel object or interact with an unfamiliar mouse was counteracted by the negative motivation to hide in exposed, large spaces. We found that TLR4(-/-) mice exhibited reduced novelty-seeking and social interaction in the large open spaces. In less stressful test apparatuses similar in size to the mouse cage, however, TLR4(-/-) mice performed normally in both novelty-seeking and social interaction tests. The reduced exploratory behaviors under approach-avoidance conflict were not due to a high anxiety level or an enhanced fear response in the TLR4(-/-) mice, as these mice showed normal anxiety and fear responses in the open field and passive avoidance tests, respectively. Importantly, the novelty-seeking behavior in the large open field induced a higher level of c-Fos activation in the nucleus accumbens shell (NAcSh) in TLR4(-/-) mice than in WT mice. Partially inactivating the NAcSh via infusion of GABA receptor agonists restored the novelty-seeking behavior of TLR4(-/-) mice. These data suggested that TLR4 is crucial for positive motivational behavior under approach-avoidance conflict. TLR4-dependent activation of neurons in the NAcSh may contribute to this phenomenon.

    Recent management research has indicated the importance of family, sleep, and recreation as nonwork activities of employees. Drawing from entrainment theory, we develop an expanded model of work-life conflict to contend that macrolevel business cycles influence the amount of time employees spend on both work and nonwork activities. Focusing solely on working adults, we test this model in a large nationally representative dataset from the Bureau of Labor Statistics that spans an 8-year period, which includes the "Great Recession" from 2007 through 2009. We find that during economic booms, employees work more and therefore spend less time with family, sleeping, and recreating. In contrast, in recessionary economies, employees spend less time working and therefore more time with family, sleeping, and recreating. Thus, we extend the theory on time-based work-to-family conflict, showing that there are potential personal and relational benefits for employees in recessionary economies.

    Approach-avoidance conflict (AAC) refers to situations associated with both rewarding and threatening outcomes. The AAC task was developed to measure AAC decision-making. Approach behavior during this task has been linked to self-reported anxiety sensitivity and has elicited anterior cingulate, insula, caudate and right dorsolateral prefrontal cortex (dlPFC) activity, with right lateral PFC tracking the extent of approach behavior. Guided by these results, we used excitatory transcranial direct current stimulation (tDCS) to demonstrate the causal involvement of right dlPFC in AAC decision-making. Participants received anodal tDCS at 1.5mA over either left or right dlPFC or sham stimulation, while performing the AAC task and a control short-term memory task. Analyses of variance (ANOVA) revealed that for individuals with high anxiety sensitivity excitatory right (but not left or sham) dlPFC stimulation elicited measurable decreases in approach behavior during conflict. Excitatory left (but not right or sham) dlPFC simulation improved performance on the control task. These results support a possible asymmetry between the contributions of right and left dlPFC to AAC resolution during emotional decision-making. Increased activity in right dlPFC may contribute to anxiety-related symptoms and, as such, serve as a neurobehavioral target of anxiolytic treatments aiming to decrease avoidance behavior. © The Author (2016).

    Full Text Available The concept of conflict, being an outcome of behaviours, is an integral part of human life. Wherever there is a difference of opinion there are chances of conflict. Managing conflict effectively demands multifarious professional abilities and acumen. To resolve and manage conflict, the organisations must understand the causes, theories, approaches and strategies of conflict management. Conflict and stress are interlinked as they are dependent on each other. It is a psychological phenomenon that requires a high level of attention and thorough understanding. It appears that there is a very little margin to remain unaffected from the clutches of stress in contemporary time.

    The current study employs a grounded theory approach to examine West African immigrants' resolution of parent-child conflict and intimate partner conflict. Data from 59 participants present an interactive social ecological framework, where a lack of resolution at one level results in attempts to resolve problems at higher levels. Four levels are identified within West African immigrants' problem solving ecology, each with specific actors in positions of authority: individual/dyadic (parents and spouses), extended family (which includes distant relatives and relatives living in home countries), community leadership (non-family elders and religious leaders), and state authorities. From participants' descriptions of family challenges emerged a picture of a social ecology in flux, with traditional, socially conservative modes of resolving family conflict transposed across migration into the more liberal and state-oriented familial context of the United States. This transposition results in a loss spiral for the traditional social ecology, differentially affecting individual actors within families. Implications for helping professionals working with new immigrant communities include identifying variability in openness to adapting structures that are not working well (e.g., patriarchal protection of abusive husbands) and supporting structures known to be associated with well being (e.g., collective monitoring of youth).

    The present study aimed at characterizing the neural correlates of conflict resolution in two variations of the Simon effect. We introduced two different Simon tasks where subjects had to identify shapes on the basis of form-from-motion perception (FFMo) within a randomly moving dot field, while (1) motion direction (motion-based Simon task) or (2) stimulus location (location-based Simon task) had to be ignored. Behavioral data revealed that both types of Simon tasks induced highly significant interference effects. Using event-related fMRI, we could demonstrate that both tasks share a common cluster of activated brain regions during conflict resolution (pre-supplementary motor area (pre-SMA), superior parietal lobule (SPL), and cuneus) but also show task-specific activation patterns (left superior temporal cortex in the motion-based, and the left fusiform gyrus in the location-based Simon task). Although motion-based and location-based Simon tasks are conceptually very similar (Type 3 stimulus-response ensembles according to the taxonomy of [Kornblum, S., Stevens, G. (2002). Sequential effects of dimensional overlap: findings and issues. In: Prinz, W., Hommel., B. (Eds.), Common mechanism in perception and action. Oxford University Press, Oxford, pp. 9-54]) conflict resolution in both tasks results in the activation of different task-specific regions probably related to the different sources of task-irrelevant information. Furthermore, the present data give evidence those task-specific regions are most likely to detect the relationship between task-relevant and task-irrelevant information.

    Full Text Available This study aimed to 1 examine relationships between uncertainty, perceived information, personal values, social support, and filial obligation among Chinese family caregivers faced with nursing home placement of an older adult family member with dementia; and 2 describe the applicability of the Decisional Conflict Scale in nursing home placement decision making among Chinese family caregivers through the integration of quantitative and qualitative data. We used a mixed-methods approach. Quantitative data analysis consisted of descriptive and correlational statistics. We utilized a thematic analysis for the qualitative data. Data transformation and data comparison techniques were used to combine qualitative and quantitative data. Thirty Chinese family caregivers living in Taiwan caring for an older adult with dementia participated in this study. We found a significant association among the quantitative findings, which indicated that perceived information, personal values, social support, and filial obligation, and nursing home placement decisional conflict. Mixed-method data analysis additionally revealed that conflicting differences existed between the traditional role of Chinese family collective decision making and the contemporary role of single family member surrogate decision making. Although the Decisional Conflict Scale can be utilized when exploring nursing home placement for an older adult with dementia among Chinese family caregivers, applicability issues existed regarding cultural beliefs and values related to filial piety and family collectivism. Findings strongly support the need for researchers to consider cultural beliefs and values when selecting tools that assess health-related decision making across cultures. Further research is needed to explore the role culture plays in nursing home decision making.

    Full Text Available A Conflict Detection and Resolution (CD&R system for manned/unmanned aerial vehicle (UAV based on Automatic Dependent Surveillance-Broadcast (ADS-B concept is designed and verified in this paper. The 900 MHz XBee-Pro is selected as data transponder to broadcast flight information among participating aircraft in omnirange. Standard Compact Position Report (CPR format packet data are automatically broadcasted by ID sequencing under Quasi-ADS-B mechanism. Time Division Multiple Access (TDMA monitoring checks the designated time slot and reallocates the conflict ID. This mechanism allows the transponder to effectively share data with multiple aircraft in near airspace. The STM32f103 microprocessor is designed to handle RF, GPS, and flight data with Windows application on manned aircraft and ground control station simultaneously. Different conflict detection and collision avoidance algorithms can be implemented into the system to ensure flight safety. The proposed UAV/CD&R using Quasi-ADS-B transceiver is tested using ultralight aircraft flying at 100–120 km/hr speed in small airspace for mission simulation. The proposed hardware is also useful to additional applications to mountain hikers for emergency search and rescue. The fundamental function by the proposed UAV/CD&R using Quasi-ADS-B is verified with effective signal broadcasting for surveillance and efficient collision alert and avoidance performance to low altitude flights.

    Bongiorno, Christian; Miccichè, Salvatore; Mantegna, Rosario N

    2017-01-01

    We present an agent based model of the Air Traffic Management socio-technical complex system aiming at modeling the interactions between aircraft and air traffic controllers at a tactical level. The core of the model is given by the conflict detection and resolution module and by the directs module. Directs are flight shortcuts that are given by air controllers to speed up the passage of an aircraft within a certain airspace and therefore to facilitate airline operations. Conflicts between flight trajectories can occur for two main reasons: either the planning of the flight trajectory was not sufficiently detailed to rule out all potential conflicts or unforeseen events during the flight require modifications of the flight plan that can conflict with other flight trajectories. Our model performs a local conflict detection and resolution procedure. Once a flight trajectory has been made conflict-free, the model searches for possible improvements of the system efficiency by issuing directs. We give an example of model calibration based on real data. We then provide an illustration of the capability of our model in generating scenario simulations able to give insights about the air traffic management system. We show that the calibrated model is able to reproduce the existence of a geographical localization of air traffic controllers' operations. Finally, we use the model to investigate the relationship between directs and conflict resolutions (i) in the presence of perfect forecast ability of controllers, and (ii) in the presence of some degree of uncertainty in flight trajectory forecast.

Our model performs a local conflict detection and resolution procedure. Once a flight trajectory has been made conflict-free, the model searches for possible improvements of the system efficiency by issuing directs. We give an example of model calibration based on real data. We then provide an illustration of the capability of our model in generating scenario simulations able to give insights about the air traffic management system. We show that the calibrated model is able to reproduce the existence of a geographical localization of air traffic controllers' operations. Finally, we use the model to investigate the relationship between directs and conflict resolutions (i in the presence of perfect forecast ability of controllers, and (ii in the presence of some degree of uncertainty in flight trajectory forecast.

  8. Beyond the futility argument: the fair process approach and time-limited trials for managing dialysis conflict.

    Futility is an ancient concept arising from Greek mythology that was resurrected for its medical application in the 1980s with the proliferation of many lifesaving technologies, including dialysis and renal transplantation. By that time, the domineering medical paternalism that characterized the pre-1960s physician-patient relationship morphed into assertive patient autonomy, and some patients began to claim the right to demand aggressive, high-technology interventions, despite physician disapproval. To counter this power struggle, the establishment of a precise definition of futility offered hope for a futility policy that would allow physicians to justify withholding or withdrawing treatment, despite patient and family objections. This article reviews the various attempts made to define medical futility and describes their limited applicability to dialysis. When futility concerns arise, physicians should recognize the opportunity to address conflict, using best practice communication skills. Physicians would also benefit from understanding the ethical principles of respect for patient autonomy, beneficence, nonmaleficence, justice, and professional integrity that underlie medical decision-making. Also reviewed is the use of a fair process approach or time-limited trial when conflict resolution cannot be achieved. These topics are addressed in the Renal Physician Association's clinical practice guideline Shared Decision-Making in the Appropriate Initiation and Withdrawal from Dialysis, with which nephrologists should be well versed. A case presentation of intractable calciphylaxis in a new dialysis patient illustrates the pitfalls of physicians not fully appreciating the ethics of medical decision-making and failing to use effective conflict management approaches in the clinical practice guideline.

    Alexander Kosenkov

    2016-09-01

    Full Text Available In this paper, an attempt is made to analyze the potential threats and consequences of cyber conflicts and, in particular, the risks of a global cyber conflict. The material is based on a comprehensive analysis of the nature of cyber conflict and its elements from both technical and societal points of view. The approach used in the paper considers the societal component as an essential part of cyber conflicts, allowing basics of cyber conflicts often disregarded by researchers and the public to be highlighted. Finally, the conclusion offers an opportunity to consider cyber conflict as the most advanced form of modern warfare, which imposes the most serious threat and whose effect could be comparable to weapons of mass destruction.

    Variable-centered research has found complex relationships between child well-being and two critical aspects of the post-divorce family environment: the level of non-residential father involvement (i.e., contact and supportive relationship) with their children and the level of conflict between the father and mother. However, these analyses fail to capture individual differences based on distinct patterns of interparental conflict, father support and father contact. Using a person-centered latent profile analysis, the present study examined (1) profiles of non-residential father contact, support, and interparental conflict in the 2 years following divorce (N = 240), when children (49 % female) were between 9 and 12 years of age and (2) differences across profiles in concurrent child adjustment outcomes as well as outcomes 6 years later. Four profiles of father involvement were identified: High Contact-Moderate Conflict-Moderate Support, Low Contact-Moderate Conflict-Low Support, High Conflict-Moderate Contact-Moderate Support, and Low Conflict-Moderate Contact-Moderate Support. Concurrently, children with fathers in the group with high conflict were found to have significantly greater internalizing and externalizing problems compared to all other groups. Six years later, children with fathers in the group with low contact and low support were found to have greater internalizing and externalizing problems compared to children with fathers in the high conflict group, and also greater internalizing problems compared to children with fathers in the low conflict group. These results provide insight into the complex relationship among non-residential fathers' conflict, contact, and support in child adjustment within divorcing families.

    This article describes a methodology for developing culturally grounded assessment measures in conflict and postconflict situations. A mixed-method design was used in Kabul, Afghanistan, to identify local indicators of distress and develop the 22-item Afghan Symptom Checklist (ASCL). The ASCL contains several indigenous items and items familiar to Western mental health professionals. The ASCL was pilot tested and subsequently administered to 324 adults in 8 districts of Kabul. It demonstrated excellent reliability (alpha=.93) and good construct validity, correlating strongly with a measure of exposure to war-related violence and loss (r=.70). Results of the survey indicate moderate levels of distress among Afghan men and markedly higher levels of distress and impaired functioning among women (and widows in particular).

    Zhang, Zhe; Cheng, Wen-Wu

    2014-05-01

    The main aim of palliative care is to provide relief from pain and distressing symptoms and to offer psychological and spiritual support to enhance the quality of life. We present a case of an elderly Chinese patient with major depressive disorder who was a doctor himself, and through his experience of treating patients had become afraid about the complications of advanced disease. He wished to forego treatment, which was in conflict with those of his family. This report highlights the role of the palliative medical team in improving outcomes through enabling communication to occur between the family and the patient to achieve the best outcomes. This should lead to better training provision for the involved medical staff.

  18. Managing Conflict: A Guide for the Pharmacy Manager.

    2015-06-01

    Managing conflict among a variety of people and groups is a necessary part of creating a high performance pharmacy department. As new pharmacy managers enter the workforce, much of their success depends on how they manage conflict. The goal of this article is to provide a guide for the pharmacy director on conflict in the workplace. By evaluating each type of conflict, we can learn how to respond when it occurs. Resolving conflict requires a unique and individualized approach, and the strategy used may often be based on the situational context and the personality of the employee or manager. The more that pharmacy leaders can engage in conflict resolution with employees and external leaders, the more proactive they can be in achieving positive results. If pharmacy directors understand the source of conflicts and use management strategies to resolve them, they will ensure that conflicts result in a more effective patient-centered pharmacy service.

    2015-12-01

    Despite a growing awareness of the increased prevalence of intimate partner violence and sexual violence in conflict and post-conflict settings, much less is known about the dynamics, as well as the interventions that would be effective at individual, relational, and structural levels. In addition to the human capital lost by conflict violence, gender-based violence (GBV) poses a grave threat to the post-conflict rehabilitation process. With regard to violence that occurs during and post conflict, research must take into consideration the different types of violence that share similar causes as the larger conflict as well as become widespread as a result of the conflict and use existing frameworks to build future interventions. Researchers are trying to understand the interplay of personal, situational, and socio-cultural factors in conflict settings that combine to cause GBV and lead to guidelines for program planning to address the health and social needs of survivors as well as to prevent further GBV. These actions result from a growing recognition that violence represents a serious public health problem, is an important cause of many physical and psychological illnesses, and can cause social disruptions that impede reconstruction efforts for generations. This review studies the manifestations of GBV during and following the Ivoirian Civil War, juxtaposes them against narratives, as well as lists relevant interventions at the individual, relational, community, and institutional levels. Part of a growing literature that aims to better understand the nature of violence during and after conflict and to plan effective responses to it, this study hopes to suggest solutions for the situation of Côte d'Ivoire and elsewhere.

    Human-elephant conflict (HEC) is a recurring problem that appears wherever the range of elephants and humans overlap. Different methods including the use of electric fences are used worldwide to mitigate this conflict. Nonetheless, elephants learn quickly that their tusks do not conduct electricity and use them to break down fences (fence-breakers). In Lewa Wildlife Conservancy, Kenya, destructive elephants (Loxodonta africana) were monitored between 2010 and 2013. The fence-breaking rate reached four incidents (fence-breaking) per elephant per 100 days. Ten bull males and 57 females were identified as fence-breakers. The bulls were involved in 85.07% and the females in 14.93% of incidents. The Kenya Wildlife Service approved detusking (partial cutting of tusks) in four of the 10 fence-breakers as a way of preventing them from breaking down fences, thereby mitigating HEC in the Conservancy. The result of the detusking was a drastic six-fold reduction in damage to fences (range: 1.67 to 14.5 times less fence-breaking) by the four worst fence-breaker elephants, because with trimmed tusks elephants lack the tools to break down fences. Detusking could not totally eliminate fence destruction because, despite lacking their tools, elephants can still destroy fences using their heads, bodies and trunks, albeit less effectively. On the other hand, apart from inherent aesthetic considerations, the detusking of elephants may have certain negative effects on factors such as elephants' social hierarchies, breeding, mate selection and their access to essential minerals and food. Elephant detusking seems to be effective in drastically reducing fence-breaking incidents, nonetheless its negative effects on behaviour, access to food and its aesthetical consequences still need to be further studied and investigated.

  2. The communication of "pure" group-based anger reduces tendencies toward intergroup conflict because it increases out-group empathy.

    The communication of group-based anger in intergroup conflict is often associated with destructive conflict behavior. However, we show that communicating group-based anger toward the out-group can evoke empathy and thus reduce intergroup conflict. This is because it stresses the value of maintaining a positive long-term intergroup relationship, thereby increasing understanding for the situation (in contrast to the communication of the closely related emotion of contempt). Three experiments demonstrate that the communication of group-based anger indeed reduces destructive conflict intentions compared with (a) a control condition (Experiments 1-2), (b) the communication of group-based contempt (Experiment 2), and (c) the communication of a combination of group-based anger and contempt (Experiments 2-3). Moreover, results from all three experiments reveal that empathy mediated the positive effect of communicating "pure" group-based anger. We discuss the implications of these findings for the theory and practice of communicating emotions in intergroup conflicts.

  3. Improved Conflict Detection for Graph Transformation with Attributes

    Directory of Open Access Journals (Sweden)

    Géza Kulcsár

    2015-04-01

    Full Text Available In graph transformation, a conflict describes a situation where two alternative transformations cannot be arbitrarily serialized. When enriching graphs with attributes, existing conflict detection techniques typically report a conflict whenever at least one of two transformations manipulates a shared attribute. In this paper, we propose an improved, less conservative condition for static conflict detection of graph transformation with attributes by explicitly taking the semantics of the attribute operations into account. The proposed technique is based on symbolic graphs, which extend the traditional notion of graphs by logic formulas used for attribute handling. The approach is proven complete, i.e., any potential conflict is guaranteed to be detected.

    Chai, C; Wong, Y D

    2014-02-01

    At intersection, vehicles coming from different directions conflict with each other. Improper geometric design and signal settings at signalized intersection will increase occurrence of conflicts between road users and results in a reduction of the safety level. This study established a cellular automata (CA) model to simulate vehicular interactions involving right-turn vehicles (as similar to left-turn vehicles in US). Through various simulation scenarios for four case cross-intersections, the relationships between conflict occurrences involving right-turn vehicles with traffic volume and right-turn movement control strategies are analyzed. Impacts of traffic volume, permissive right-turn compared to red-amber-green (RAG) arrow, shared straight-through and right-turn lane as well as signal setting are estimated from simulation results. The simulation model is found to be able to provide reasonable assessment of conflicts through comparison of existed simulation approach and observed accidents. Through the proposed approach, prediction models for occurrences and severity of vehicle conflicts can be developed for various geometric layouts and traffic control strategies.

    2009-02-01

    Using survey data from 240 employees working in a variety of organizations, the authors examined the relations among commitment to the supervisor, leader-member exchange, supervisor-based self-esteem (SBSE), and relationship and substantive supervisor-subordinate conflicts. They found affective commitment was negatively related to both types of conflicts; perceived lack of alternatives commitment was positively related to relationship conflicts; and leader-member exchange was negatively related to substantive conflicts. SBSE was negatively associated with both types of conflicts. In addition, when SBSE was low, affective commitment was more strongly related to both types of conflicts, and normative commitment more strongly and positively related to substantive conflicts. The authors discuss the implications of these findings for the understanding of employee-supervisor conflicts.

    Theories often consider behaviors in isolation of conflicting and facilitating personal goals. We conducted interviews with 13 people in cardiac rehabilitation, investigating whether eliciting physical activity (PA) control beliefs sufficiently captures goal conflict and goal facilitation. We assessed PA, intention, and control beliefs using standard elicitation methods and then assessed goal conflict and goal facilitation. Twelve participants described conflicting, and all described facilitating, personal goals. Most goal facilitation (94%) and conflict (82%) beliefs were identified beyond the control belief elicitation. Goal facilitation and conflict are not captured in a standard control belief elicitation and may supplement single-behavior models to understand PA.

    2014-01-01

    Professional nurses are taking on leadership roles of diverse healthcare teams. Development of conflict competence is essential, yet requires self-awareness and deliberate effort. Heightened awareness of one's preferred conflict style and cognizance of the implications of overuse and/or underuse of these styles is important. DESIGN/METHODOLOGICAL APPROACH: A pre-post survey design (N = 14) used paired sample T-test. Paired sample correlations and an overview of the paired sample test are reported. Students gained self-awareness about their preferred conflict style, recognized that each conflict style has its utility depending on any given situation, and demonstrated a difference in their most frequently used style. Limited data conveys conflict behavior styles among pre-licensure nursing; however, students can influence their own environments (either causing or fueling situations) by their personal conflict-handling styles. Early development of these skills can raise awareness and cultivate ease in the management of conflict within varied settings.

  11. A Simple Two Aircraft Conflict Resolution Algorithm

    Science.gov (United States)

    Chatterji, Gano B.

    2006-01-01

    Conflict detection and resolution methods are crucial for distributed air-ground traffic management in which the crew in, the cockpit, dispatchers in operation control centers sad and traffic controllers in the ground-based air traffic management facilities share information and participate in the traffic flow and traffic control functions. This paper describes a conflict detection, and a conflict resolution method. The conflict detection method predicts the minimum separation and the time-to-go to the closest point of approach by assuming that both the aircraft will continue to fly at their current speeds along their current headings. The conflict resolution method described here is motivated by the proportional navigation algorithm, which is often used for missile guidance during the terminal phase. It generates speed and heading commands to rotate the line-of-sight either clockwise or counter-clockwise for conflict resolution. Once the aircraft achieve a positive range-rate and no further conflict is predicted, the algorithm generates heading commands to turn back the aircraft to their nominal trajectories. The speed commands are set to the optimal pre-resolution speeds. Six numerical examples are presented to demonstrate the conflict detection, and the conflict resolution methods.

  12. Study on dynamic multi-objective approach considering coal and water conflict in large scale coal group

    In the process of coal mining, destruction and pollution of groundwater in has reached an imminent time, and groundwater is not only related to the ecological environment, but also affect the health of human life. Similarly, coal and water conflict is still one of the world's problems in large scale coal mining regions. Based on this, this paper presents a dynamic multi-objective optimization model to deal with the conflict of the coal and water in the coal group with multiple subordinate collieries and arrive at a comprehensive arrangement to achieve environmentally friendly coal mining strategy. Through calculation, this paper draws the output of each subordinate coal mine. And on this basis, we continue to adjust the environmental protection parameters to compare the coal production at different collieries at different stages under different attitude of the government. At last, the paper conclude that, in either case, it is the first arrangement to give priority to the production of low-drainage, high-yield coal mines.

    2014-01-01

    To investigate associations between nurse work practice environment measured at department level and individual level work-family conflict on burnout, measured as emotional exhaustion, depersonalization and personal accomplishment among Swedish RNs. A multilevel model was fit with the individual RN at the 1st, and the hospital department at the 2nd level using cross-sectional RN survey data from the Swedish part of RN4CAST, an EU 7th framework project. The data analysed here is based on a national sample of 8,620 RNs from 369 departments in 53 hospitals. Generally, RNs reported high values of personal accomplishment and lower values of emotional exhaustion and depersonalization. High work-family conflict increased the risk for emotional exhaustion, but for neither depersonalization nor personal accomplishment. On department level adequate staffing and good leadership and support for nurses reduced the risk for emotional exhaustion and depersonalization. Personal accomplishment was statistically significantly related to staff adequacy. The findings suggest that adequate staffing, good leadership, and support for nurses are crucial for RNs' mental health. Our findings also highlight the importance of hospital managers developing policies and practices to facilitate the successful combination of work with private life for employees.

    Given the challenges to ensuring facility-based care in conflict settings, the Women's Refugee Commission and partners have been pursuing a community-based approach to providing medical care to survivors of sexual assault in Karen State, eastern Burma. This new model translates the 2004 World Health Organization's Clinical Management of Rape Survivors facility-based protocol to the community level through empowering community health workers to provide post-rape care. The aim of this innovative study is to examine the safety and feasibility of community-based medical care for survivors of sexual assault to contribute to building an evidence base on alternative models of care in humanitarian settings. A process evaluation was implemented from July-October 2011 to gather qualitative feedback from trained community health workers, traditional birth attendants, and community members. Two focus group discussions were conducted among the highest cadre health care workers from the pilot and non-pilot sites. In Karen State, eight focus group discussions were convened among traditional birth attendants and 10 among women and men of reproductive age. Qualitative feedback contributed to an understanding of the model's feasibility. Pilot site community health workers showed interest in providing community-based care for survivors of sexual assault. Traditional birth attendants attested to the importance of making this care available. Community health workers were deeply aware of the need to maintain confidentiality and offer compassionate care. They did not raise safety as an excess concern in the provision of treatment. Data speak to the promising "feasibility" of community-based post-rape care. More time, awareness-raising, and a larger catchment population are necessary to answer the safety perspective. The pilot is an attempt to translate facility-based protocol to the community level to offer solutions for settings where traditional methods of post-rape care are not

    2016-02-01

    Imagine yourself facing someone who might attack your group--if you could control your emotions, how would you want to feel toward that person? We argue that the goals people have for their group dictate how they want to feel on behalf of their group. We further propose that these group-based emotional preferences, in turn, influence how people actually feel as group members and how they react to political events. We conducted 9 studies to test our proposed model. In a pilot study, we showed that political ideology is related to how people want to feel toward outgroup members, even when controlling for how they want to feel in general, or how they actually feel toward outgroup members. In Studies A1-A3, we demonstrated that group-based emotional preferences are linked to emotional experience and that both mediate links between political ideology and political reactions. In Study A4, we showed that political ideology influences emotional preferences, emotional experiences and political reactions. Next, in Studies B1-B4, we demonstrated that changing group-based emotional preferences can shape group-based emotional experiences and consequently influence political reactions. By suggesting that group-based emotions are motivated, our findings point to new directions for advancing conflict resolution. (c) 2016 APA, all rights reserved).

    Families of critically ill patients are often asked to make difficult decisions to pursue, withhold, or withdraw aggressive care or resuscitative measures, exercising "substituted judgment" from the imagined standpoint of the patient. Conflict may arise between intensive care unit (ICU) physicians and family members regarding the optimal course of care. To characterize how ICU physicians approach and manage conflict with surrogates regarding end-of-life decision-making. Semistructured interviews were conducted with 18 critical care physicians from four academically affiliated hospitals. Interview transcripts were analyzed using methods of grounded theory. Physicians described strategies for engaging families to resolve conflict about end-of-life decision-making and tending to families' emotional health. Physicians commonly began by gauging family receptiveness to recommendations from the healthcare team. When faced with resistance to recommendations for less aggressive care, approaches ranged from deference to family wishes to various persuasive strategies designed to change families' minds, and some of those strategies may be counterproductive or harmful. The likelihood of deferring to family in the event of conflict was associated with the perceived sincerity of the family's "substituted judgment" and the ability to control patient pain and suffering. Physicians reported concern for the family's emotional needs and made efforts to alleviate the burden on families by assuming decision-making responsibility and expressing nonabandonment and commitment to the patient. Physicians were attentive to repairing damage to their relationship with the family in the aftermath of conflict. Finally, physicians described their own emotional responses to conflict, ranging from frustration and anxiety to satisfaction with successful resolution of conflict. Critical care physicians described a complex and multilayered approach to physician-family conflict. The reported strategies

    2001-01-01

    In this volume, Ting-Toomey and Oetzel accomplish two objectives: to explain the culture-based situational conflict model, including the relationship among conflict, ethnicity, and culture; and, second, integrate theory and practice in the discussion of interpersonal conflict in culture, ethnic, and gender contexts. While the book is theoretically directed, it is also a down-to-earth practical book that contains ample examples, conflict dialogues, and critical incidents. Managing Intercultural Conflict Effectively helps to illustrate the complexity of intercultural conflict interactions and readers will gain a broad yet integrative perspective in assessing intercultural conflict situations. The book is a multidisciplinary text that draws from the research work of a variety of disciplines such as cross-cultural psychology, social psychology, sociology, marital and family studies, international management, and communication.

    2016-01-01

    Previous studies have found a negative association between intragroup conflict and both employees' health and performance, including the quality of service that employees provide. However, some authors have indicated that such negative effects of intragroup conflict depend on how conflict is managed. In addition, at individual level, research is increasingly emphasizing the role of psychological strengths (i.e., psychological capital) as predictors of health and performance. Thus, this research addresses both a main effect at individual level (psychological capital on burnout/quality of service) and a moderated cross-level model (2-2-1: intragroup conflict, conflict management climate and burnout/quality of service) in a cross-sectional survey study ( N = 798 workers nested in 55 units/facilities). Results revealed a main effect of psychological capital on both burnout ( r = -0.50) and quality of service ( r = 0.28). Also, there was an association between intragroup relationship conflict and burnout ( r = 0.33). Finally, there was an interaction effect in which conflict management climate buffers the negative association between intragroup conflict and quality of service. Practical implications of these results for developing positive and healthy organizations that prevent potential psychosocial risks at group level while promote individual strengths are discussed.

  12. Automatic Conflict Detection on Contracts

    Science.gov (United States)

    Fenech, Stephen; Pace, Gordon J.; Schneider, Gerardo

    Many software applications are based on collaborating, yet competing, agents or virtual organisations exchanging services. Contracts, expressing obligations, permissions and prohibitions of the different actors, can be used to protect the interests of the organisations engaged in such service exchange. However, the potentially dynamic composition of services with different contracts, and the combination of service contracts with local contracts can give rise to unexpected conflicts, exposing the need for automatic techniques for contract analysis. In this paper we look at automatic analysis techniques for contracts written in the contract language mathcal{CL}. We present a trace semantics of mathcal{CL} suitable for conflict analysis, and a decision procedure for detecting conflicts (together with its proof of soundness, completeness and termination). We also discuss its implementation and look into the applications of the contract analysis approach we present. These techniques are applied to a small case study of an airline check-in desk.

  14. Feasibility of neuro-morphic computing to emulate error-conflict based decision making.

    Energy Technology Data Exchange (ETDEWEB)

    Branch, Darren W.

    2009-09-01

    A key aspect of decision making is determining when errors or conflicts exist in information and knowing whether to continue or terminate an action. Understanding the error-conflict processing is crucial in order to emulate higher brain functions in hardware and software systems. Specific brain regions, most notably the anterior cingulate cortex (ACC) are known to respond to the presence of conflicts in information by assigning a value to an action. Essentially, this conflict signal triggers strategic adjustments in cognitive control, which serve to prevent further conflict. The most probable mechanism is the ACC reports and discriminates different types of feedback, both positive and negative, that relate to different adaptations. Unique cells called spindle neurons that are primarily found in the ACC (layer Vb) are known to be responsible for cognitive dissonance (disambiguation between alternatives). Thus, the ACC through a specific set of cells likely plays a central role in the ability of humans to make difficult decisions and solve challenging problems in the midst of conflicting information. In addition to dealing with cognitive dissonance, decision making in high consequence scenarios also relies on the integration of multiple sets of information (sensory, reward, emotion, etc.). Thus, a second area of interest for this proposal lies in the corticostriatal networks that serve as an integration region for multiple cognitive inputs. In order to engineer neurological decision making processes in silicon devices, we will determine the key cells, inputs, and outputs of conflict/error detection in the ACC region. The second goal is understand in vitro models of corticostriatal networks and the impact of physical deficits on decision making, specifically in stressful scenarios with conflicting streams of data from multiple inputs. We will elucidate the mechanisms of cognitive data integration in order to implement a future corticostriatal-like network in silicon

    Full Text Available Urban rivers are socioecological systems, and restored habitats may be attractive to both sensitive species and recreationists. Understanding the potential conflicts between ecological and recreational values is a critical issue for the development of a sustainable river-management plan. Habitat models are very promising tools for the ecological evaluation of river restoration projects that are already concluded, ongoing, or even to be planned. With our paper, we make a first attempt at integrating recreational user pressure into habitat modeling. The objective of this study was to analyze whether human impact is likely to hinder the re-establishment of a target species despite the successful restoration of physical habitat structures in the case of the restoration of the Isar River in Munich (Germany and the target fish species Chondostroma nasus L. Our analysis combined high-resolution 2D hydrodynamic modeling with mapping of recreational pressure and used an expert-based procedure for modeling habitat suitability. The results are twofold: (1 the restored river contains suitable physical habitats for population conservation but has low suitability for recruitment; (2 densely used areas match highly suitable habitats for C. nasus. In the future, the integrated modeling procedure presented here may allow ecological refuge for sensitive target species to be included in the design of restoration and may help in the development of visitor-management plans to safeguard biodiversity and recreational ecosystem services.

    Full Text Available The Marcan account of Jesus riding into Jerusalem on a donkey, cursing the fig tree and overturning the tables of the money changers in the temple provides a classic scriptural reference point for a Christian discussion of conflict. Drawing on psychological type theory and on the reader perspective proposed by the SIFT (sensing, intuition, feeling and thinking approach to biblical hermeneutics and liturgical preaching, this study tests the theory that different psychological types will interpret this classic passage differently. Data collected in two residential programmes concerned with Christianity and conflict from type-aware participants confirmed characteristic differences between the approaches of sensing types and intuitive types and between the approaches of thinking types and feeling types.

  18. Conflict resolution in the zoning of eco-protected areas in fast-growing regions based on game theory.

    Science.gov (United States)

    Lin, Jinyao; Li, Xia

    2016-04-01

    Zoning eco-protected areas is important for ecological conservation and environmental management. Rapid and continuous urban expansion, however, may exert negative effects on the performance of practical zoning designs. Various methods have been developed for protected area zoning, but most of them failed to consider the conflicts between urban development (for the benefit of land developers) and ecological protection (local government). Some real-world zoning schemes even have to be modified occasionally after the lengthy negotiations between the government and land developers. Therefore, our study has presented a game theory-based method to deal with this problem. Future urban expansion in the study area will be predicted by a logistic regression cellular automaton, while eco-protected areas will be delimitated using multi-objective optimization algorithm. Then, two types of conflicts between them can be resolved based on game theory, a theory of decision-making. We established a two-person dynamic game for each conflict zone. The ecological compensation mechanism was taken into account by simulating the negotiation processes between the government and land developers. A final zoning scheme can be obtained when the two sides reach agreements. The proposed method is applied to the eco-protected area zoning in Guangzhou, a fast-growing city in China. The experiments indicate that the conflicts between eco-protection and urban development will inevitably arise when using only traditional zoning methods. Based on game theory, our method can effectively resolve those conflicts, and can provide a relatively reasonable zoning scheme. This method is expected to support policy-making in environmental management and urban planning. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available In spunlace nonwovens industry, the maintenance task is very complex, it requires experts and operators collaboration. In this paper, we propose a new approach integrating an agent- based modelling with case-based reasoning that utilizes similarity measures and preferences module. The main purpose of our study is to compare and evaluate the most suitable similarity measure for our case. Furthermore, operators that are usually geographically dispersed, have to collaborate and negotiate to achieve mutual agreements, especially when their proposals (diagnosis lead to a conflicting situation. The experimentation shows that the suggested agent-based approach is very interesting and efficient for operators and experts who collaborate in INOTIS enterprise.

  2. A Combined Approach to Cartographic Displacement for Buildings Based on Skeleton and Improved Elastic Beam Algorithm

    2014-01-01

    Scale reduction from source to target maps inevitably leads to conflicts of map symbols in cartography and geographic information systems (GIS). Displacement is one of the most important map generalization operators and it can be used to resolve the problems that arise from conflict among two or more map objects. In this paper, we propose a combined approach based on constraint Delaunay triangulation (CDT) skeleton and improved elastic beam algorithm for automated building displacement. In this approach, map data sets are first partitioned. Then the displacement operation is conducted in each partition as a cyclic and iterative process of conflict detection and resolution. In the iteration, the skeleton of the gap spaces is extracted using CDT. It then serves as an enhanced data model to detect conflicts and construct the proximity graph. Then, the proximity graph is adjusted using local grouping information. Under the action of forces derived from the detected conflicts, the proximity graph is deformed using the improved elastic beam algorithm. In this way, buildings are displaced to find an optimal compromise between related cartographic constraints. To validate this approach, two topographic map data sets (i.e., urban and suburban areas) were tested. The results were reasonable with respect to each constraint when the density of the map was not extremely high. In summary, the improvements include (1) an automated parameter-setting method for elastic beams, (2) explicit enforcement regarding the positional accuracy constraint, added by introducing drag forces, (3) preservation of local building groups through displacement over an adjusted proximity graph, and (4) an iterative strategy that is more likely to resolve the proximity conflicts than the one used in the existing elastic beam algorithm.

    Complex interpersonal conflicts are inevitable in the high speed, high stakes, pressured work of health care. Poorly managed, conflict saps productivity, erodes trust, and spawns additional disputes. Well managed, conflict can enhance the self-confidence and self-esteem of the parties, build relationships, and engender creative solutions beyond expectations. Just as thoughtful differential diagnosis precedes optimum treatment in the doctor-patient relationship, management of conflict is greatly enhanced when preceded by careful assessment. In the first of two articles, the authors present a diagnostic approach, the Conflict Management Checklist, to increase self-awareness and decrease anxiety around conflict.

  8. The Needs of Victims: An Empirical Categorization Based on Interpersonal Conflicts

    2013-09-01

    Full Text Available As a consequence of interpersonal conflicts, needs of the victimized are violated. These needs have to be addressed in order to achieve reconciliation. Due to the heterogeneity of need categories in scholarly research, we scrutinized which need categories can be empirically identified. 478 participants reported on an experienced interpersonal conflict. They responded to 109 items evaluating the perceived need violation for the conflict they reported on. By means of exploratory factor analysis with a random sub-sample (n1 = 239, six need categories were extracted. These are the need for respect, the need for meaning, the need for acceptance, the need for pleasure, the need for self-efficacy, and the need for safety. Confirmatory factor analyses showed that these needs replicated in the second random sub-sample (n2 = 239 as well as across sub-samples with people who had experienced an interpersonal conflict of lower severity of transgression (nA = 257 or higher severity of transgression (nB = 221. In addition, each of the need categories mediated the relationship between the severity of transgression and the desire for revenge. Yet, the results for the two need categories “pleasure” and “safety” have to be interpreted with caution due to a lack of scalar invariance. Among the other four need categories, respect was identified as the only independent mediator variable. Implications for the transformation of interpersonal conflict and further scholarly inquiries are discussed.

    2016-06-01

    This study used a sequential two-phase explanatory design. The first phase of this mixed-methods design aimed to explore conflict resolution strategies in adolescent dating couples, and the second phase to document, from both the perspective of the individual and of the couple, dyadic interaction patterns distinguishing youth inflicting dating violence from those who do not. A sample of 39 heterosexual couples (mean age 17.8 years) participated in semi-structured interviews and were observed during a 45 min dyadic interaction. At phase 1, qualitative analysis revealed three main types of conflict resolution strategies: 1) negotiating expectations and individual needs; 2) avoiding conflicts or their resolution; 3) imposing personal needs and rules through the use of violence. At phase 2, we focused on couples with conflictive patterns. Results indicate that couples who inflict violence differ from nonviolent couples by their tendency to experience conflicts when in disagreement and to resort to negative affects as a resolution strategy. In addition, while at an individual level, they show a tendency to withdraw from conflict and to use less positive affect, at a dyadic level they present less symmetry. Results offer important insights for prevention programs. Copyright © 2016. Published by Elsevier Ltd.

    We investigated the use of vocalizations called "grunts," "girneys," and "coos" accompanied by post-conflict affiliative interaction between former opponents (reconciliation) in Japanese macaques (Macaca fuscata). Although reconciliation functions to repair bonds, such interactions sometimes entail risks of receiving further aggression. Vocalizations can be used at a distance from the former opponent; thus, we predict that vocalizations are used particularly by victims of a conflict, and are frequently used in situations of uncertainty when it is difficult for them to estimate whether the former opponent will resume aggression. In addition, we predict that vocalizations are effective in preventing further aggression. To test these hypotheses, we conducted observations of post-conflict and matched-control situations in female Japanese macaques living in a free-ranging group. We found that former opponents tended to be attracted to each other within the first minute following a conflict, thus demonstrating reconciliation behavior. Vocalizations were more frequently used by the victims in post-conflict interactions than under control situations; however, this tendency was not found in aggressors. When affiliation with the former opponent occurred, victims were more likely to use vocalizations towards less familiar opponents. These findings suggest that Japanese macaques used vocalizations more often when interacting with less predictable former opponents. Victims were more likely to receive aggression from former aggressors when engaged in affiliations with them than under no such affiliations. No significant differences were found in the probability of the victims receiving aggression, regardless of whether they used vocalizations; thus, whether the victim benefits from using vocalizations in these contexts remains unclear. Japanese macaques form despotic societies and therefore, further aggression was inevitable, to some degree, after a conflict. The use of

    The rapid increase in terror-related activities, shift of battlefield into civilian locations, and participation of youth in acts of violence underscore the need to find novel frameworks for youth interventions. Building on the Israeli-Palestinian conflict and social neuroscience models we developed an eight-week dialogue group-intervention for youth growing up amidst intractable conflict. Eighty-eight Israeli-Jewish and Arab-Palestinian adolescents (16-18years) were randomly assigned to intervention or control groups. Before (T1) and after (T2) intervention, one-on-one conflict interaction with outgroup member were videotaped, oxytocin levels assayed, attitudes self-reported, and youth interviewed regarding national conflict. We tested the hypothesis that dialogue intervention would enhance empathic behavior and increase oxytocin levels following interaction with outgroup member. Intervention increased youth perspective-taking on national conflict. Oxytocin increased from T1 to T2 only for adolescents undergoing intervention who improved perspective taking in the process. Structural equation modelling charted three pathways to behavioral empathy toward outgroup member at T2; via endogenous oxytocin, empathic cognitions, and dialogue intervention; however, an alternative model without the intervention arm was non-significant. Our findings highlight the important role of empathy in programs for inter-group reconciliation and support evolutionary models on the precarious balance between the neurobiology of affiliation and the neurobiology of outgroup derogation.

    M M Akulich

    2016-12-01

    Full Text Available The article considers the contradictions and conflicts of the contemporary Russian education focusing on the opportunities for conflict management. The research is based on the institutional and system approaches, in particular on the sociological conceptions of social conflict and social cohesion. The author conducted a historical and sociological analysis of social conflicts and social cohesion in the educational sphere, and such conflicts seem to be the result of the contradictions inherent in this social institution. The article identifies basic types of conflicts in the Russian education, and the ways of resolving them by the subjects of the educational system for such conflicts are manageable, especially within the interaction of educational system and society. To verify the proposed typology of conflicts in the contemporary Russian education the author conducted an empirical study to develop a system of practical measures that will help to improve the quality of learning of pupils and students, and will have a positive impact on the functioning and development of the contemporary Russian society. Thus, the article may be useful to sociologists, teachers, educational managers and readers interested in the specifics of social conflicts and the ways for resolving conflict situations.

    2015-08-01

    To explore clinician and family experiences of conflict in paediatric services, in order to map the trajectory of conflict escalation. Qualitative interview study, employing extreme-case sampling. Interviews were analysed using an iterative thematic approach to identify common themes regarding the experience and escalation of conflict. Thirty-eight health professionals and eight parents. All participants had direct experience of conflict, including physical assault and court proceedings, at the interface of acute and palliative care. Two teaching hospitals, one district general hospital and two paediatric hospices in England, in 2011. Conflicts escalate in a predictable manner. Clearly identifiable behaviours by both clinicians and parents are defined as mild, moderate and severe. Mild describes features like the insensitive use of language and a history of unresolved conflict. Moderate involves a deterioration of trust, and a breakdown of communication and relationships. Severe marks disintegration of working relationships, characterised by behavioural changes including aggression, and a shift in focus from the child's best interests to the conflict itself. Though conflicts may remain at one level, those which escalated tended to move sequentially from one level to the next. Understanding how conflicts escalate provides clinicians with a practical, evidence-based framework to identify the warning signs of conflict in paediatrics.

  2. How is environmental conflict addressed by SIA?

    International Nuclear Information System (INIS)

    Barrow, C.J.

    2010-01-01

    The fields of Environmental Conflict Management (ECM), Environmental Conflict Resolution (ECR), and Peace and Conflict Impact Assessment (PCIA) have become well established; however, as yet there has not been much use of Social Impact Assessment (SIA) to manage environmental conflicts. ECM, ECR and PCIA are mainly undertaken when problems are advanced or, more likely, have run their course (post-conflict). This paper examines how conflict is addressed by SIA and whether there is potential to develop it for more proactive assessment of conflicts (pre-conflict or while things develop). SIA has the potential to identify and clarify the cause(s) of environmental and natural resources conflicts, and could possibly enable some avoidance or early mitigation. A promising approach may be for 'conflict-aware' SIA to watch for critical conflict stages or thresholds and to monitor stakeholders. Effective conflict-aware SIA might also significantly contribute to efforts to achieve sustainable development.

    A wide variety of information sources on medicines is available for pregnant women. When using multiple information sources, there is the risk that information will vary or even conflict. The objective of this multinational study was to analyze the extent to which pregnant women use multiple information sources and the consequences of conflicting information, and to investigate which maternal sociodemographic, lifestyle, and medical factors were associated with these objectives. An anonymous Internet-based questionnaire was made accessible during a period of 2 months, on 1 to 4 Internet websites used by pregnant women in 5 regions (Eastern Europe, Western Europe, Northern Europe, Americas, Australia). A total of 7092 responses were obtained (n=5090 pregnant women; n=2002 women with a child younger than 25 weeks). Descriptive statistics and logistic regression analysis were used. Of the respondents who stated that they needed information, 16.16% (655/4054) used one information source and 83.69% (3393/4054) used multiple information sources. Of respondents who used more than one information source, 22.62% (759/3355) stated that the information was conflicted. According to multivariate logistic regression analysis, factors significantly associated with experiencing conflict in medicine information included being a mother (OR 1.32, 95% CI 1.11-1.58), having university (OR 1.33, 95% CI 1.09-1.63) or other education (OR 1.49, 95% CI 1.09-2.03), residing in Eastern Europe (OR 1.52, 95% CI 1.22-1.89) or Australia (OR 2.28, 95% CI 1.42-3.67), use of 3 (OR 1.29, 95% CI 1.04-1.60) or >4 information sources (OR 1.82, 95% CI 1.49-2.23), and having ≥2 chronic diseases (OR 1.49, 95% CI 1.18-1.89). Because of conflicting information, 43.61% (331/759) decided not to use medication during pregnancy, 30.30% (230/759) sought a new information source, 32.67% (248/759) chose to rely on one source and ignore the conflicting one, 25.03% (190/759) became anxious, and 2.64% (20/759) did

  7. Livelihoods, conflict and aid programming: is the evidence base good enough?

    Mallett, Richard; Slater, Rachel

    2016-04-01

    In conflict-affected situations, aid-funded livelihood interventions are often tasked with a dual imperative: to generate material welfare benefits and to contribute to peacebuilding outcomes. There may be some logic to such a transformative agenda, but does the reality square with the rhetoric? Through a review of the effectiveness of a range of livelihood promotion interventions--from job creation to microfinance--this paper finds that high quality empirical evidence is hard to come by in conflict-affected situations. Many evaluations appear to conflate outputs with impacts and numerous studies fail to include adequate information on their methodologies and datasets, making it difficult to appraise the reliability of their conclusions. Given the primary purpose of this literature--to provide policy guidance on effective ways to promote livelihoods--this silence is particularly concerning. As such, there is a strong case to be made for a restrained and nuanced handling of such interventions in conflict-affected settings. © 2016 The Author(s).

  8. Disrupted insula-based neural circuit organization and conflict interference in trauma-exposed youth

    Full Text Available Childhood trauma exposure is a potent risk factor for psychopathology. Emerging research suggests that aberrant saliency processing underlies the link between early trauma exposure and later cognitive and socioemotional deficits that are hallmark of several psychiatric disorders. Here, we examine brain and behavioral responses during a face categorization conflict task, and relate these to intrinsic connectivity of the salience network (SN. The results demonstrate a unique pattern of SN dysfunction in youth exposed to trauma (n = 14 relative to comparison youth (n = 19 matched on age, sex, IQ, and sociodemographic risk. We find that trauma-exposed youth are more susceptible to conflict interference and this correlates with higher fronto-insular responses during conflict. Resting-state functional connectivity data collected in the same participants reveal increased connectivity of the insula to SN seed regions that is associated with diminished reward sensitivity, a critical risk/resilience trait following stress. In addition to altered intrinsic connectivity of the SN, we observed altered connectivity between the SN and default mode network (DMN in trauma-exposed youth. These data uncover network-level disruptions in brain organization following one of the strongest predictors of illness, early life trauma, and demonstrate the relevance of observed neural effects for behavior and specific symptom dimensions. SN dysfunction may serve as a diathesis that contributes to illness and negative outcomes following childhood trauma.

  9. Equity, Inclusion and Conflict in Community Based Forest Management: A Case of Salghari Community Forest in Nepal

    Sushant Acharya

    2015-12-01

    Full Text Available The equity and inclusion issues are widely observed in Community Based Forest Management (CBFM and Community Forestry (CF is not an exception. Community Forest User Groups (CFUGs are portrayed as robust grassroots institutions for forest management and group governance. However, many contemporary researches have shown that CFUGs are still governed by some influential local elites who hardly practice equity and inclusion. In this context, objectives of this paper are: to explore how equity and inclusion issues lead CFUGs fall into internal conflicts; and to demonstrate how CFUGs are able to address such issues locally. The study was carried out in Salghari CFUG of Ratnechaur, Myagdi. Semi-structured interview and focused group discussion were key tools used for data collection. Livelihoods and Social Inclusion Framework and Equity Framework are used for data analysis. The findings of the research revealed that dalits and non-dalits of Salghari fall into internal conflict regarding the use of forest products. The conflict was then managed through amendments in CF provisions and change in CF leadership. This paper concludes that execution of equity and inclusion provisions in CF, secures access to assets for disadvantaged people from CBFM. However, this demands empowerment of these people and facilitating role of external agency.

    Efficient communication, conflict management and cooperation are the key factors of a successful patient care. This study is part of an international comparative research. The aim of this study is to unfold conflicts among healthcare workers. 73 healthcare workers were interviewed using a standardized interview protocol. The in-person interviews used the critical incident method. 30 interviews (15 doctors, 15 nurses) were analysed with the Atlas.ti 7 content analysis software. The sources, types, effects of conflicts and conflict management strategies were investigated. The content analysis unfolded the specificities of conflicts in healthcare based on personal experiences. Organizational hierarchy was a substantial source of conflict, especially among physicians, which originates from implicit rules. As a result of the avoiding conflict management the conflicts remain partly unresolved which has negative individual and group effect. Our conceptual framework helps to develop a proper intervention specific to healthcare. Orv. Hetil., 2017, 158(16), 625-632.

  11. Stimulus conflict triggers behavioral avoidance.

    Science.gov (United States)

    Dignath, David; Eder, Andreas B

    2015-12-01

    According to a recent extension of the conflict-monitoring theory, conflict between two competing response tendencies is registered as an aversive event and triggers a motivation to avoid the source of conflict. In the present study, we tested this assumption. Over five experiments, we examined whether conflict is associated with an avoidance motivation and whether stimulus conflict or response conflict triggers an avoidance tendency. Participants first performed a color Stroop task. In a subsequent motivation test, participants responded to Stroop stimuli with approach- and avoidance-related lever movements. These results showed that Stroop-conflict stimuli increased the frequency of avoidance responses in a free-choice motivation test, and also increased the speed of avoidance relative to approach responses in a forced-choice test. High and low proportions of response conflict in the Stroop task had no effect on avoidance in the motivation test. Avoidance of conflict was, however, obtained even with new conflict stimuli that had not been presented before in a Stroop task, and when the Stroop task was replaced with an unrelated filler task. Taken together, these results suggest that stimulus conflict is sufficient to trigger avoidance.

    Directory of Open Access Journals (Sweden)

    C.J. Hugo

    2010-07-01

    Full Text Available The apartheid system caused deep rifts in South African society, and even following the dawn of democracy, society in South Africa continues to struggle with violence and conflict, ethnic differences, mass action and poverty. Christian leaders have an important part to play in conflict resolution. Conflict management in organisations incorporates negotiation as a means of conflict resolution. A number of approaches to conflict resolution contribute to this approach; these include forcing, avoiding, accommodating, compromising and collaborating. Christian leaders, however, favour reconciliation as a means of resolving conflict. A Christian approach to conflict resolution needs to take cognisance of the existential aspect of conflict. Examples of such approaches are those of Dreyer, who speaks of reconciliation as a dilemma for forgiveness, and Kistner, who explores the way in which the use of narratives rather than reallife stories in the Truth and Reconciliation Commission reduced the severity of trauma. The social construction of trauma in “Mamelodi” by Brigid Hess, which presents a shift from forgiveness to a journey taken along with the perpetrators, and the belief of Desmond Tutu in the healing brought about by the ubuntu philosophy, are evaluated here as being detrimental to reconciliation. Based on the examples cited, an approach to conflict resolution entailing a clear integration of the biblical approach to reconciliation and dialogical inquiry (DI is proposed as an appropriate intervention approach for Christian leaders. The present contribution is offered from within the discipline of Practical Theology, with a focus on Pastoral Counseling.

  15. Methodological approaches based on business rules

    Directory of Open Access Journals (Sweden)

    Anca Ioana ANDREESCU

    2008-01-01

    Full Text Available Business rules and business processes are essential artifacts in defining the requirements of a software system. Business processes capture business behavior, while rules connect processes and thus control processes and business behavior. Traditionally, rules are scattered inside application code. This approach makes it very difficult to change rules and shorten the life cycle of the software system. Because rules change more quickly than the application itself, it is desirable to externalize the rules and move them outside the application. This paper analyzes and evaluates three well-known business rules approaches. It also outlines some critical factors that have to be taken into account in the decision to introduce business rules facilities in a software system. Based on the concept of explicit manipulation of business rules in a software system, the need for a general approach based on business rules is discussed.

  19. Conflict management: importance and implications.

    Science.gov (United States)

    McKibben, Laurie

    2017-01-26

    Conflict is a consistent and unavoidable issue within healthcare teams. Despite training of nurse leaders and managers around areas of conflict resolution, the problem of staff relations, stress, sickness and retention remain. Conflict arises from issues with interpersonal relationships, change and poor leadership. New members of staff entering an already established healthcare team should be supported and integrated, to encourage mutual role respect between all team members and establish positive working relationships, in order to maximise patient care. This paper explores the concept of conflict, the importance of addressing causes of conflict, effective management, and the relevance of positive approaches to conflict resolution. Good leadership, nurturing positive team dynamics and communication, encourages shared problem solving and acceptance of change. Furthermore mutual respect fosters a more positive working environment for those in healthcare teams. As conflict has direct implications for patients, positive resolution is essential, to promote safe and effective delivery of care, whilst encouraging therapeutic relationships between colleagues and managers.

    Usually, a hydrometeorological information system is faced with great data flows, but the data levels are often excessive, depending on the observed region of the water. The paper presents advanced buoy communication technologies based on multiagent interaction and data exchange between several monitoring system nodes. The proposed management of buoy communication is based on a clustering algorithm, which enables the performance of the hydrometeorological information system to be enhanced. The experiment is based on the design and analysis of the inexpensive but reliable Baltic Sea autonomous monitoring network (buoys), which would be able to continuously monitor and collect temperature, waviness, and other required data. The proposed approach of multiagent based buoy communication enables all the data from the costal-based station to be monitored with limited transition speed by setting different tasks for the agent-based buoy system according to the clustering information.

    2017-10-01

    In drug discovery, network-based approaches are expected to spotlight our understanding of drug action across multiple layers of information. On one hand, network pharmacology considers the drug response in the context of a cellular or phenotypic network. On the other hand, a chemical-based network is a promising alternative for characterizing the chemical space. Both can provide complementary support for the development of rational drug design and better knowledge of the mechanisms underlying the multiple actions of drugs. Recent progress in both concepts is discussed here. In addition, a network-based approach using drug-target-therapy data is introduced as an example. © 2017 Wiley-VCH Verlag GmbH & Co.

    Students today are likely to be assigned to project teams or to be project managers almost immediately in their first job. Managing Projects: A Team-Based Approach was written for a wide range of stakeholders, including project managers, project team members, support personnel, functional mangers who provide resources for projects, project customers (and customer representatives), project sponsors, project subcontractors, and anyone who plays a role in the project delivery process. The need for project management is on the rise as product life cycles compress, demand for IT systems increases, and business takes on an increasingly global character. This book adds to the project management knowledge base in a way that fills an unmet need—it shows how teams can apply many of the standard project management tools, as well as several tools that are relatively new to the field. Managing Projects: A Team-Based Approach offers the academic rigor found in most textbooks along with the practical attributes often foun...

    Full Text Available The article’s objective is a critical reflection upon the capacity of the models of risk communication in the intervention of socioenvironmental conflicts. The research was of an exploratory nature and took as case studies two important conflict based on energy development in Chile: the thermoelectrica Castilla and hydroelectric Hidroaysén. It was an integrated study (qualitativequantitative that used semi-structured interviews and survey methods, for which we analyzed the first instruments for the elaboration of this text. The results reveal technical and reflexive dimensions for a pertinent communication. In the technical dimension, information management with variables such as integration, actuality, significance and objectivity are marked, and the dimension of information channels with variables such as accessibility, persuasion and trust. In the reflexive dimension, clarity and transparency of information are visibilized, with variables like simplicity, integrity, interactivity and the precise, convenient and adequate means of informing.

    The Millennium Development Goals (MDGs) set very high targets for women's reproductive health through reductions in maternal and infant mortality, among other things. Reductions in maternal mortality and morbidity can be achieved through various different approaches, such as the confidential review of maternal deaths, use of evidence-based treatments and interventions, using a health systems approach, use of information technology, global and regional partnerships, and making pregnancy safer through initiatives that increase the focus on human rights. A combination of these and other approaches can have a synergistic impact on reductions in maternal mortality. This paper highlights some of the current global efforts on safer pregnancy with a focus on reproductive rights. We encourage readers to do more in every corner of the world to advocate for women's reproductive rights and, in this way, we may achieve the MDGs by 2015.

    2012-01-01

    Full Text Available Constructive conflict resolution programmes are based on the idea that children and youth do no have sufficient knowledge of the procedures and skills for conflict resolution, which is why the conflicts they take part in soon become destructive. Notwithstanding the indubitable practical significance of the constructive conflict resolution programmes, it can be objected that they are not sufficiently based on empirical findings about the characteristics of conflicts in childhood and adolescence. Hence, this paper explores different types of conflict with peers and friends with the aim of determining the preferred conflict resolution strategies and using the obtained results to consider the implications for the improvement of constructive conflict resolution programmes. The research was conducted on the sample of 286 adolescents. The method of hypothetical conflict situations was used for studying the preferred conflict resolution strategies. The key results, which should be taken into account when developing constructive conflict resolution programmes, indicate that the preference for a conflict resolution strategy varies depending on conflict type (problem solving is mostly used in conflicts occurring due to opinion differences and disrespect of agreement, unlike the conflicts arising due to provocations, stubbornness and dishonesty and relationship types (in conflicts with friends, adolescents prefer problem solving, while in peer conflicts they more frequently opt for competition.

  12. Betwixt and between: Role conflict, role ambiguity and role definition in project-based dual-leadership structures.

    Ebbers, Joris J; Wijnberg, Nachoem M

    2017-11-01

    Project-based organizations in the film industry usually have a dual-leadership structure, based on a division of tasks between the dual leaders - the director and the producer - in which the former is predominantly responsible for the artistic and the latter for the commercial aspects of the film. These organizations also have a role hierarchically below and between the dual leaders: the 1st assistant director. This organizational constellation is likely to lead to role conflict and role ambiguity experienced by the person occupying that particular role. Although prior studies found negative effects of role conflict and role ambiguity, this study shows they can also have beneficial effects because they create space for defining the role expansively that, in turn, can be facilitated by the dual leaders defining their own roles more narrowly. In a more general sense, this study also shows the usefulness of analyzing the antecedents and consequences of roles, role definition, and role crafting in connection to the behavior of occupants of adjacent roles.

  14. Using conflict theory to explore the role of nursing home social workers in home- and community-based service utilization.

    Fogler, Sarah

    2009-11-01

    Nursing home social work (NHSW) practitioners are central to home- and community-based service (HCBS) utilization. They assist residents with long-term care (LTC) decision-making and coordinate community-based LTC supports and services for older adults transitioning back into the community after a rehabilitative nursing home (NH) stay. As members of multiple groups, they must simultaneously balance the needs of NH residents, the NH organization, and social policies related to LTC. To date, policy research on HCBS has been atheoretical in that it has not accounted for the possible inherent conflicts that adversely affect the discharge planning practices of NHSW practitioners. This article applies the Conflict Theory to (a) explore the competing interests of the NH industry and the nation's government, (b) examine the potential effect of these competing interests on the effectiveness of NHSW discharge planning practices, and (c) present a conceptual framework to further investigate the relationship between NHSW and both individual LTC outcomes and national policy initiatives aimed at increasing HCBS utilization.

    2018-02-01

    Tuberculosis is an infectious disease associated with significant mortality and morbidity worldwide, particularly in developing countries. The rise of antibiotic resistance in Mycobacterium tuberculosis (Mtb) urgently demands the development of new drug leads to tackle resistant strains. Fragment-based methods have recently emerged at the forefront of pharmaceutical development as a means to generate more effective lead structures, via the identification of fragment molecules that form weak but high quality interactions with the target biomolecule and subsequent fragment optimization. This review highlights a number of novel inhibitors of Mtb targets that have been developed through fragment-based approaches in recent years.

  17. Information system conflicts: causes and types

    2015-01-01

    Full Text Available Conflicts are an inherent part of organizational life and managers deal with confrontations and conflicts on an almost daily basis. Information Systems (IS implementations are a type of change that often leads to open or hidden conflicts. Managers and others involved can only deal with such conflicts effectively if they understand the nature and causes of information system conflicts (IS conflicts. To contribute to such an understanding, this study focuses on the analysis of IS conflicts. In so doing, it aims to identify various types of IS conflicts and to develop a framework that can be helpful in assessing these conflicts. To this end, we have conducted a meta-ethnographic study – that is, we synthesized earlier case studies in which IS conflicts are described. We purposefully selected 11 descriptions of IS conflicts and we analyzed the topics, contexts, and processes of these conflicts. Based on this analysis, we propose a two-dimensional framework of IS conflicts that leads to a categorization involving four IS conflict types: task; implementation process; structure; and value conflicts. Based on the conflicts that were studied, this paper also reveals that, in reality, many IS conflicts have a hybrid form and develop from one type to another over time.

    de Castro, Ana Paula A.; da Silva, José D. S.

    2007-02-01

    This paper describes a neural network based multiscale image restoration approach. Multilayer perceptrons are trained with artificial images of degraded gray level circles, in an attempt to make the neural network learn inherent space relations of the degraded pixels. The present approach simulates the degradation by a low pass Gaussian filter blurring operation and the addition of noise to the pixels at pre-established rates. The training process considers the degraded image as input and the non-degraded image as output for the supervised learning process. The neural network thus performs an inverse operation by recovering a quasi non-degraded image in terms of least squared. The main difference of the approach to existing ones relies on the fact that the space relations are taken from different scales, thus providing relational space data to the neural network. The approach is an attempt to come up with a simple method that leads to an optimum solution to the problem. Considering different window sizes around a pixel simulates the multiscale operation. In the generalization phase the neural network is exposed to indoor, outdoor, and satellite degraded images following the same steps use for the artificial circle image.

  1. Conflicts about Conflict of Interest.

    Kelly, Terrence

    2016-07-01

    Pharmaceutical representatives use detailing, gift giving, and the donation of free samples as a means to gain access to and influence over physicians. In biomedical ethics, there has been an ongoing debate as to whether these practices constitute an unethical conflict of interest (COI) on the part of the physician. Underlying this debate are the following antecedent questions: (1) what counts as a conflict of interest, (2) when are such conflicts unethical, and (3) how should the ethical physician respond to conflicts? This article distinguishes between two perspectives that have been developed on these issues: a reliable performance model (PM) and a trustworthiness model (TM). PM advocates argue that a conflict of interest can only be established by demonstrating that a particular influence is undermining the reliability of the physician's judgment, and this requires empirical evidence of negative patient outcomes. TM advocates, on the other hand, argue that because of the fiduciary nature of the patient-physician relationship, physicians have an obligation to develop and be worthy of patient trust. A COI, on this view, is a condition that undermines the warrant for patients to judge a physician as trustworthy. Although there is much that is right in the PM, it is argued that the TM does a better job of responsibly addressing the unique vulnerabilities of the patient. The TM is then applied to the practices of detailing, gift giving, and sample donation. It is concluded that these practices constitute an unethical conflict of interest.

    Education has explored and utilised multiple approaches in attempts to enhance the learning and teaching opportunities available to adult learners. Traditional pedagogy has been both directly and indirectly affected by andragogy and transformational learning, consequently widening our understandings and approaches toward view teaching and learning. Within the context of nurse education, a major challenge has been to effectively apply these educational approaches to the complex, unpredictable and challenging environment of practice based learning. While not offered as a panacea to such challenges, heutagogy is offered in this discussion paper as an emerging and potentially highly congruent educational framework to place around practice based learning. Being an emergent theory its known conceptual underpinnings and possible applications to nurse education need to be explored and theoretically applied. Through placing the adult learner at the foreground of grasping learning opportunities as they unpredictability emerge from a sometimes chaotic environment, heutagogy can be argued as offering the potential to minimise many of the well published difficulties of coordinating practice with faculty teaching and learning.

    2018-01-01

    The SLS Program chose to implement a Model-based Design and Model-based Requirements approach for managing component design information and system requirements. This approach differs from previous large-scale design efforts at Marshall Space Flight Center where design documentation alone conveyed information required for vehicle design and analysis and where extensive requirements sets were used to scope and constrain the design. The SLS Navigation Team has been responsible for the Program-controlled Design Math Models (DMMs) which describe and represent the performance of the Inertial Navigation System (INS) and the Rate Gyro Assemblies (RGAs) used by Guidance, Navigation, and Controls (GN&C). The SLS Navigation Team is also responsible for the navigation algorithms. The navigation algorithms are delivered for implementation on the flight hardware as a DMM. For the SLS Block 1-B design, the additional GPS Receiver hardware is managed as a DMM at the vehicle design level. This paper provides a discussion of the processes and methods used to engineer, design, and coordinate engineering trades and performance assessments using SLS practices as applied to the GN&C system, with a particular focus on the Navigation components. These include composing system requirements, requirements verification, model development, model verification and validation, and modeling and analysis approaches. The Model-based Design and Requirements approach does not reduce the effort associated with the design process versus previous processes used at Marshall Space Flight Center. Instead, the approach takes advantage of overlap between the requirements development and management process, and the design and analysis process by efficiently combining the control (i.e. the requirement) and the design mechanisms. The design mechanism is the representation of the component behavior and performance in design and analysis tools. The focus in the early design process shifts from the development and

    An approach to the development of performance based regulations (PBR's) is described. Initially, a framework is constructed that consists of a function hierarchy and associated measures. The function at the top of the hierarchy is described in terms of societal objectives. Decomposition of this function into subordinate functions and their subsequent decompositions yield the function hierarchy. ''Bottom'' functions describe the roles of system components. When measures are identified for the performance of each function and means of aggregating performances to higher levels are established, the framework may be employed for developing PBR's. Consideration of system flexibility and performance uncertainty guide in determining the hierarchical level at which regulations are formulated. Ease of testing compliance is also a factor. To show the viability of the approach, the framework developed by Lawrence Livermore Laboratory for the Nuclear Regulatory Commission for evaluation of material control systems at fixed facilities is presented

    Thrombin has multiple functions in blood coagulation and its regulation is central to maintaining the balance between hemorrhage and thrombosis. Empirical and computational methods that capture thrombin generation can provide advancements to current clinical screening of the hemostatic balance at the level of the individual. In any individual, procoagulant and anticoagulant factor levels together act to generate a unique coagulation phenotype (net balance) that is reflective of the sum of its developmental, environmental, genetic, nutritional and pharmacological influences. Defining such thrombin phenotypes may provide a means to track disease progression pre-crisis. In this review we briefly describe thrombin function, methods for assessing thrombin dynamics as a phenotypic marker, computationally derived thrombin phenotypes versus determined clinical phenotypes, the boundaries of normal range thrombin generation using plasma composition based approaches and the feasibility of these approaches for predicting risk.

  6. Toward a child-centered approach to evaluating claims of alienation in high-conflict custody disputes.

    Nichols, Allison M

    2014-02-01

    Theories of parental alienation abound in high-conflict custody cases. The image of one parent brainwashing a child against the other parent fits with what we think we know about family dynamics during divorce. The concept of a diagnosable "Parental Alienation Syndrome" ("PAS") developed as an attempt to explain this phenomenon, but it has been widely discredited by mental health professionals and thus fails the standard for evidentiary admissibility. Nevertheless, PAS and related theories continue to influence the decisions of family courts, and even in jurisdictions that explicitly reject such theories, judges still face the daunting task of resolving these volatile cases. In the midst of this highly adversarial process, children deserve independent representation to ensure that their interests remain front and center. Mandating the appointment of guardians ad litem in cases involving allegations of abuse or alienation will assist courts in conducting individualized, fact-specific investigations into such allegations to craft custody orders that serve the best interests of children.

    Full Text Available It has been found in the study that potential conflicts are natural for public sector projects. Among the factors, that predetermine it, one can distinguish the following: the opposite to the processes of making changes; competition of participants during the allocation of project resources; different opportunities to access the project product; insufficient consideration of interested parties’ interests; context conflicts; directing the project to resolve the conflict in the territory; unsuccessful selection of the project team. Consequently, the article deals with the issues related to the definition of the peculiarities of the «conflict sensitivity» implementation mechanisms in the public sector projects. This topic has not been studied thoroughly in the specialized publications on public administration in Ukraine. Definitions of main related categories of the «conflict sensitivity» domain based on Conflict Sensitivity Consortium guidelines have been described in the study: «conflict sensitivity», «conflict», «conflict analysis», «conflict sensitivity analysis». The main ideas on the peculiarities of conflict-sensitive project / program management implementation mechanisms in the context of ensuring the success of local development projects by the integration of «conflict sensitivity» into all three phases of the project cycle, under which the intervention is implemented, are as follows: conflict-sensitive planning; conflict-sensitive implementation; conflict-sensitive monitoring and evaluation. The example of the conflict-sensitive project management use is: EUNPACK international project «Good intentions, mixed results – A conflict sensitive understanding of the EU comprehensive approach to conflict and crisis mechanisms», which aims to develop recommendations on the improvement of the EU crises response mechanisms by the increase of their sensitivity to conflict and context.

    Drees, A

    1987-08-01

    The working climate and therapeutic possibilities in a hospital are determined, among other factors, by emotional processes in everyday ward routine. Team conflicts and their solution are not infrequently reflections of the open-mindedness of a hospital towards the complexity of these processes. However, the complex interlocking of transference processes with rôle-specific and personality-conditioned behaviour patterns makes it more difficult to understand and make use of these emotional processes within the team. We present a specific attempt to working up emotional conflicts in a patient-centred approach via focussing on self-rating of the team workers in respect of mood, feeling tone and imagination. Specific internal Balint groups are the fulcrum. To distinguish this method from the theory of object-directed transference of emotions and constructions of relations, the theoretical basis of this group method is seen in the systemic paradigm with which patient-focussed solution functions are obtained in respect of process orientation and instrumental part functions of the team workers. In this connection it was explored to what extent the following factors can be interpreted as patient-induced phenomena: therapeutic and rôle behaviour, hospital structures and administrative squabbles, internal and external walls of a mental hospital.

    Frishmuth, R.A.; Benson, L.A.

    1995-01-01

    The principle objective of remedial actions is to protect human health and the environment. Risk assessments are the only defensible tools available to demonstrate to the regulatory community and public that this objective can be achieved. Understanding the actual risks posed by site-related contamination is crucial to designing cost-effective remedial strategies. All to often remedial actions are overdesigned, resulting in little to no increase in risk reduction while increasing project cost. Risk-based remedial actions have recently been embraced by federal and state regulators, industry, government, the scientific community, and the public as a mechanism to implement rapid and cost-effective remedial actions. Emphasizing risk reduction, rather than adherence to ambiguous and generic standards, ensures that only remedial actions required to protect human health and the environment at a particular site are implemented. Two sites are presented as case studies on how risk-based approaches are being used to remediate two petroleum hydrocarbon contaminated sites. The sites are located at two US Air Force Bases, Wurtsmith Air Force Base (AFB) in Oscoda, Michigan and Malmstrom AFB in Great Falls, Montana

  20. The influence of work-family conflict trajectories on self-rated health trajectories in Switzerland: a life course approach.

    Science.gov (United States)

    Cullati, Stéphane

    2014-07-01

    Self-rated health (SRH) trajectories tend to decline over a lifetime. Moreover, the Cumulative Advantage and Disadvantage (CAD) model indicates that SRH trajectories are known to consistently diverge along socioeconomic positions (SEP) over the life course. However, studies of working adults to consider the influence of work and family conflict (WFC) on SRH trajectories are scarce. We test the CAD model and hypothesise that SRH trajectories diverge over time according to socioeconomic positions and WFC trajectories accentuate this divergence. Using longitudinal data from the Swiss Household Panel (N = 2327 working respondents surveyed from 2004 to 2010), we first examine trajectories of SRH and potential divergence over time across age, gender, SEP and family status using latent growth curve analysis. Second, we assess changes in SRH trajectories in relation to changes in WFC trajectories and divergence in SRH trajectories according to gender, SEP and family status using parallel latent growth curve analysis. Three measures of WFC are used: exhaustion after work, difficulty disconnecting from work, and work interference in private family obligations. The results show that SRH trajectories slowly decline over time and that the rate of change is not influenced by age, gender or SEP, a result which does not support the CAD model. SRH trajectories are significantly correlated with exhaustion after work trajectories but not the other two WFC measures. When exhaustion after work trajectories are taken into account, SRH trajectories of higher educated people decline slower compared to less educated people, supporting the CAD hypothesis.

  1. Efficient approach for reliability-based optimization based on weighted importance sampling approach

    International Nuclear Information System (INIS)

    Yuan, Xiukai; Lu, Zhenzhou

    2014-01-01

    An efficient methodology is presented to perform the reliability-based optimization (RBO). It is based on an efficient weighted approach for constructing an approximation of the failure probability as an explicit function of the design variables which is referred to as the ‘failure probability function (FPF)’. It expresses the FPF as a weighted sum of sample values obtained in the simulation-based reliability analysis. The required computational effort for decoupling in each iteration is just single reliability analysis. After the approximation of the FPF is established, the target RBO problem can be decoupled into a deterministic one. Meanwhile, the proposed weighted approach is combined with a decoupling approach and a sequential approximate optimization framework. Engineering examples are given to demonstrate the efficiency and accuracy of the presented methodology

  2. Thermo-energetic design of machine tools a systemic approach to solve the conflict between power efficiency, accuracy and productivity demonstrated at the example of machining production

    CERN Document Server

    2015-01-01

    The approach to the solution within the CRC/TR 96 financed by the German Research Foundation DFG aims at measures that will allow manufacturing accuracy to be maintained under thermally unstable conditions with increased productivity, without an additional demand for energy for tempering. The challenge of research in the CRC/TR 96 derives from the attempt to satisfy the conflicting goals of reducing energy consumption and increasing accuracy and productivity in machining. In the current research performed in 19 subprojects within the scope of the CRC/TR 96, correction and compensation solutions that influence the thermo-elastic machine tool behaviour efficiently and are oriented along the thermo-elastic functional chain are explored and implemented. As part of this general objective, the following issues must be researched and engineered in an interdisciplinary setting and brought together into useful overall solutions:   1.  Providing the modelling fundamentals to calculate the heat fluxes and the resulti...

  3. Conflicts between employee preferences and ergonomic recommendations in shift scheduling: regulation based on consent is not sufficient

    Full Text Available OBJECTIVE: Contribution to the discussion of the role of participation/consent of employees in working hours regulation. METHODS: Exploratory analysis of conflicts between preferences of employees and ergonomic recommendations in shift scheduling by analysing a large number of participative shift scheduling projects. RESULTS: The analysis showed that very often the pursuit of higher income played the major role in the decision making process of employees and employees preferred working hours in conflict with health and safety principles. CONCLUSIONS: First, the consent of employees or the works council alone does not ensure ergonomically sound schedules. Besides consent, risk assessment procedures seem to be a promising but difficult approach. Secondly, more research is necessary to check the applicability of recommendations under various settings, to support the risk assessment processes and to improve regulatory approaches to working hours.OBJETIVO: Contribuir para a discussão do papel da participação/consentimento dos empregados na regulamentação das horas de trabalho. MÉTODOS: Realizou-se um estudo exploratório dos conflitos existentes entre as preferências dos empregados e as recomendações ergonômicas no planejamento de esquemas de trabalho em turnos, analisando-se um grande número de projetos participativos de planejamento dos turnos. RESULTADOS: O estudo mostrou que, com freqüência, a busca por um rendimento maior teve um papel importante no processo de tomada de decisão dos empregados, quando estes optaram pelas horas de trabalho em oposição aos princípios de saúde e segurança. CONCLUSÕES: Em primeiro lugar, o consentimento dos empregados ou da comissão de trabalhadores por si só não garante horários salutares do ponto de vista ergonômico. Além do consentimento, processos de avaliação de risco parecem ser uma abordagem promissora embora complicada. Em segundo lugar, fazem-se necessários mais estudos para

  4. Peptide Based Radiopharmaceuticals: Specific Construct Approach

    Energy Technology Data Exchange (ETDEWEB)

    Som, P; Rhodes, B A; Sharma, S S

    1997-10-21

    The objective of this project was to develop receptor based peptides for diagnostic imaging and therapy. A series of peptides related to cell adhesion molecules (CAM) and immune regulation were designed for radiolabeling with 99mTc and evaluated in animal models as potential diagnostic imaging agents for various disease conditions such as thrombus (clot), acute kidney failure, and inflection/inflammation imaging. The peptides for this project were designed by the industrial partner, Palatin Technologies, (formerly Rhomed, Inc.) using various peptide design approaches including a newly developed rational computer assisted drug design (CADD) approach termed MIDAS (Metal ion Induced Distinctive Array of Structures). In this approach, the biological function domain and the 99mTc complexing domain are fused together so that structurally these domains are indistinguishable. This approach allows construction of conformationally rigid metallo-peptide molecules (similar to cyclic peptides) that are metabolically stable in-vivo. All the newly designed peptides were screened in various in vitro receptor binding and functional assays to identify a lead compound. The lead compounds were formulated in a one-step 99mTc labeling kit form which were studied by BNL for detailed in-vivo imaging using various animals models of human disease. Two main peptides usingMIDAS approach evolved and were investigated: RGD peptide for acute renal failure and an immunomodulatory peptide derived from tuftsin (RMT-1) for infection/inflammation imaging. Various RGD based metallopeptides were designed, synthesized and assayed for their efficacy in inhibiting ADP-induced human platelet aggregation. Most of these peptides displayed biological activity in the 1-100 µM range. Based on previous work by others, RGD-I and RGD-II were evaluated in animal models of acute renal failure. These earlier studies showed that after acute ischemic injury the renal cortex displays

    Bras, Susana; Pinho, Armando J

    2015-08-01

    Using the electrocardiogram signal (ECG) to identify and/or authenticate persons are problems still lacking satisfactory solutions. Yet, ECG possesses characteristics that are unique or difficult to get from other signals used in biometrics: (1) it requires contact and liveliness for acquisition (2) it changes under stress, rendering it potentially useless if acquired under threatening. Our main objective is to present an innovative and robust solution to the above-mentioned problem. To successfully conduct this goal, we rely on information-theoretic data models for data compression and on similarity metrics related to the approximation of the Kolmogorov complexity. The proposed measure allows the comparison of two (or more) ECG segments, without having to follow traditional approaches that require heartbeat segmentation (described as highly influenced by external or internal interferences). As a first approach, the method was able to cluster the data in three groups: identical record, same participant, different participant, by the stratification of the proposed measure with values near 0 for the same participant and closer to 1 for different participants. A leave-one-out strategy was implemented in order to identify the participant in the database based on his/her ECG. A 1NN classifier was implemented, using as distance measure the method proposed in this work. The classifier was able to identify correctly almost all participants, with an accuracy of 99% in the database used.

  8. Linear systems a measurement based approach

    Bhattacharyya, S P; Mohsenizadeh, D N

    2014-01-01

    This brief presents recent results obtained on the analysis, synthesis and design of systems described by linear equations. It is well known that linear equations arise in most branches of science and engineering as well as social, biological and economic systems. The novelty of this approach is that no models of the system are assumed to be available, nor are they required. Instead, a few measurements made on the system can be processed strategically to directly extract design values that meet specifications without constructing a model of the system, implicitly or explicitly. These new concepts are illustrated by applying them to linear DC and AC circuits, mechanical, civil and hydraulic systems, signal flow block diagrams and control systems. These applications are preliminary and suggest many open problems. The results presented in this brief are the latest effort in this direction and the authors hope these will lead to attractive alternatives to model-based design of engineering and other systems.

    Maternal mortality rates can be adversely affected by armed conflict, implying a greater level of vulnerability among women, and is often linked to the lack of or limited access to maternal healthcare during conflict. Previous research in Uganda has shown that armed conflict negatively impacts women's utilization of maternal healthcare services for a multitude of reasons at the individual, health-system and political levels. This study compared aggregated Demographic and Health Surveys data from 13 districts in Northern Uganda, a conflict-affected region, with data from the rest of the country, for the use of maternal healthcare services for the years 1988, 1995, 2000, 2006 and 2011, using statistical analyses and logistic regression. Specific indicators for maternal healthcare utilization included contraceptive use, antenatal care, skilled assistance at birth and institutional delivery. Use of contraception and institutional deliveries among women in Northern Uganda was significantly lower compared to the rest of the country. However, skilled assistance at birth among women in Northern Uganda was significantly higher. The findings in this study show that armed conflict can have a negative impact on aspects of maternal healthcare such as contraceptive use and institutional deliveries; however, other indicators such as skilled assistance at birth were seen to be better among conflict-affected populations. This reiterates the complex nature of armed conflict and the interplay of different factors such as conflict intensity, existing health systems and services, and humanitarian interventions that could influence maternal healthcare utilization.

  16. Feature-based attention and conflict monitoring in criminal offenders: interactive relations of psychopathy with anxiety and externalizing.

    Zeier, Joshua D; Newman, Joseph P

    2013-08-01

    As predicted by the response modulation model, psychopathic offenders are insensitive to potentially important inhibitory information when it is peripheral to their primary focus of attention. To date, the clearest tests of this hypothesis have manipulated spatial attention to cue the location of goal-relevant versus inhibitory information. However, the theory predicts a more general abnormality in selective attention. In the current study, male prisoners performed a conflict-monitoring task, which included a feature-based manipulation (i.e., color) that biased selective attention toward goal-relevant stimuli and away from inhibitory distracters on some trials but not others. Paralleling results for spatial cuing, feature-based cuing resulted in less distracter interference, particularly for participants with primary psychopathy (i.e., low anxiety). This study also investigated the moderating effect of externalizing on psychopathy. Participants high in psychopathy but low in externalizing performed similarly to primary psychopathic individuals. These results demonstrate that the abnormal selective attention associated with primary psychopathy is not limited to spatial attention but, instead, applies to diverse methods for establishing attentional focus. Furthermore, they demonstrate a novel method of investigating psychopathic subtypes using continuous analyses. PsycINFO Database Record (c) 2013 APA, all rights reserved.

    : Draft Model 1 Public tryouts Previous year rating Coach makes selections Can be very competitive, lacking in "character" Can result in very unequal teams Draft Model 2 Player evaluations placed into a data base Properly programmed computer projects equal teams Draft Model 3 All names placed on a blackboard Relative merits of players discussed Equal team drawn up and placed into a hat Adjustments can be made for coach's child If practical, this author suggests that coaches not pick a name for the team until the first team meeting or practice, when that task can be given to the children. In a symbolic way, this returns some of the sport to them while encouraging social interaction among new teammates, and helping the coach detect who the leaders are. Names of professional teams in the major sports, especially baseball, are to be avoided, as they fuel longstanding unconscious associations and fantasies, and may subtly tilt all participants toward the professional "win at all costs" mentality. No one draft model is perfect for every town, and even the most ethical attempt to achieve balance among teams can be severely tested by parents who request that their athlete be placed on the same team as another child for social or car pool reasons. Such requests are not inviolate, however. For example, they do not usually dictate placement in school classes, and car pools are frequently disrupted when children, in individual sports such as Tae Kwan Do, reach different ability levels, and so attend practices at different times. Baseball is no longer the national pasttime and, as we approach the millennium, American children have too many other attractive, competing interests and time demands to spontaneously organize a pick-up game. One coach shared with the author that his saddest moment in CAP League came when he arrived at 6 PM at a field that had been "reserved" for his team, and found a group of boys who were playing a pick-up game. The coach's impulse was to set his boys fre

    2011-12-01

    Four studies investigated a goal regulation view of anxious uncertainty threat (Gray & McNaughton, 2000) and ideological defense. Participants (N = 444) were randomly assigned to have achievement or relationship goals implicitly primed. The implicit goal primes were followed by randomly assigned achievement or relationship threats that have reliably caused generalized, reactive approach motivation and ideological defense in past research. The threats caused anxious uncertainty (Study 1), reactive approach motivation (Studies 2 and 3), and reactive ideological conviction (Study 4) only when threat-relevant goals had first been primed, but not when threat-irrelevant goals had first been primed. Reactive ideological conviction (Study 4) was eliminated if participants were given an opportunity to attribute their anxiety to a mundane source. Results support a goal regulation view of anxious uncertainty, threat, and defense with potential for integrating theories of defensive compensation.

  20. Stem cell-based approaches in dentistry

    Directory of Open Access Journals (Sweden)

    TA Mitsiadis

    2011-11-01

    Full Text Available Repair of dental pulp and periodontal lesions remains a major clinical challenge. Classical dental treatments require the use of specialised tissue-adapted materials with still questionable efficacy and durability. Stem cell-based therapeutic approaches could offer an attractive alternative in dentistry since they can promise physiologically improved structural and functional outcomes. These therapies necessitate a sufficient number of specific stem cell populations for implantation. Dental mesenchymal stem cells can be easily isolated and are amenable to in vitro expansion while retaining their stemness. In vivo studies realised in small and large animals have evidenced the potential of dental mesenchymal stem cells to promote pulp and periodontal regeneration, but have also underlined new important challenges. The homogeneity of stem cell populations and their quality control, the delivery method, the quality of the regenerated dental tissues and their integration to the host tissue are some of the key challenges. The use of bioactive scaffolds that can elicit effective tissue repair response, through activation and mobilisation of endogenous stem cell populations, constitutes another emerging therapeutic strategy. Finally, the use of stem cells and induced pluripotent cells for the regeneration of entire teeth represents a novel promising alternative to dental implant treatment after tooth loss. In this mini-review, we present the currently applied techniques in restorative dentistry and the various attempts that are made to bridge gaps in knowledge regarding treatment strategies by translating basic stem cell research into the dental practice.

  1. Surrogate Motherhood: A Trust-Based Approach.

    Science.gov (United States)

    Beier, Katharina

    2015-12-01

    Because it is often argued that surrogacy should not be treated as contractual, the question arises in which terms this practice might then be couched. In this article, I argue that a phenomenology of surrogacy centering on the notion of trust provides a description that is illuminating from the moral point of view. My thesis is that surrogacy establishes a complex and extended reproductive unit--the "surrogacy triad" consisting of the surrogate mother, the child, and the intending parents--whose constituents are bound together by mutual trustful commitments. Even though a trust-based approach does not provide an ultimate answer to whether surrogacy should be sanctioned or prohibited, it allows for at least some practical suggestions. In particular, I will argue that, under certain conditions, surrogacy is tenable within familial or other significant relationships, and I will stress the necessity of acknowledging the new relationships and moral commitments that result from this practice. © The Author 2015.

  2. Quality based approach for adaptive face recognition

    Abboud, Ali J.; Sellahewa, Harin; Jassim, Sabah A.

    2009-05-01

    Recent advances in biometric technology have pushed towards more robust and reliable systems. We aim to build systems that have low recognition errors and are less affected by variation in recording conditions. Recognition errors are often attributed to the usage of low quality biometric samples. Hence, there is a need to develop new intelligent techniques and strategies to automatically measure/quantify the quality of biometric image samples and if necessary restore image quality according to the need of the intended application. In this paper, we present no-reference image quality measures in the spatial domain that have impact on face recognition. The first is called symmetrical adaptive local quality index (SALQI) and the second is called middle halve (MH). Also, an adaptive strategy has been developed to select the best way to restore the image quality, called symmetrical adaptive histogram equalization (SAHE). The main benefits of using quality measures for adaptive strategy are: (1) avoidance of excessive unnecessary enhancement procedures that may cause undesired artifacts, and (2) reduced computational complexity which is essential for real time applications. We test the success of the proposed measures and adaptive approach for a wavelet-based face recognition system that uses the nearest neighborhood classifier. We shall demonstrate noticeable improvements in the performance of adaptive face recognition system over the corresponding non-adaptive scheme.

    2010-06-01

    The paper under the above mentioned title tries to develop an understanding of the question why energy relations and cooperation between the European Union and Russia in energy matters haven't been very successful over the last decade and why relations are affected by crises frequently. In order to answer these questions meaningfully, several steps need to be made: First, the paper offers a summary of recent policy debate on energy questions on the EU side. It identifies relevant participants in the ''political arena'' and describes their positioning and interaction, based on a multi-level-governance approach. Following a look at history of European energy policy developments, the paper concludes that a complex European policy field has developed recently, although there is no direct responsibility for energy matters with European institutions so far, but that the justification for any law-making in the said areas is deducted from secondary EU level responsibilities such as common market, competition law or environmental matters. However, there is a huge bandwidth of positions between political actors, civil service, parliaments, industry associations, consumers - organizations etc as well as between community and national level organizations. Not only a battle for power and competence between these levels hinders a straight and consistent energy policy across the EU, there is also significantly different focus with different players on where to put effort between conflicting objectives of the ''European Energy Triangle'', demanding (1) secure and reliable, (2) cheap and competitive as well as (3) environmentally friendly energy supplies. Despite all these differences, within the EU, a strong and well-regarded new area of policy debate has developed in the energy sector and a lot has been achieved. Observers frequently demand the EU to ''speak with one voice'' towards third parties, eg gas producing

    2017-06-01

    Full Text Available Actuality of work. Student age has the most favourable conditions for psychological, biological and social development; however, there are reasons why such natural advantages over other social groups can be completely or partially levelled. One of them is the presence of conflicts in the life of a student, a special group, among which there are women. The causes of the emergence of gender conflicts in individual social groups and the strategies for their solution have not been sufficiently explored and require further study and, therefore, are relevant. Purpose of the article is to investigate the causes of gender conflicts among students as a separate social group and to develop measures to address them and prevent them. Methodology. The research conducted in the work is based on the analysis and generalization of the causes of the emergence of gender conflicts among students, the identification of the main sources of information that form the consciousness of children and adolescents, and also influence their attitude to gender equality. Originality. The nature of gender conflicts has been quite effectively studied for a long time. However, the scope of research is limited to the most numerous social groups, such as the family, labour collective, political and public organizations, etc. Being a dynamic and socio-demographic formation, the students perform an important function in society – it takes a direct part in the transformation of all spheres of the life activity of the society. Based on the study of the objective conditions of the social environment with certain models of socialization that form the consciousness of students from early childhood, a three-component system of influence was first proposed, which is aimed at overcoming gender inequality and preventing gender conflicts among students. At the same time, the interaction of the components of the system will allow to minimize the gender inequality index in our country

    Human immunodeficiency virus (HIV)-infected patients have a high prevalence of chronic pain and opioid use, making HIV care a critical setting for improving the safety of opioid prescribing. Little is known about HIV treatment providers' perspectives about opioid prescribing to patients with chronic pain. The authors administered a questionnaire and conducted semistructured telephone interviews with 18 HIV treatment providers (infectious disease specialists, general internists, family medicine physicians, nurse practitioners, and physician assistants) in Bronx, NY. Open-ended interview questions focused on providers' experiences, beliefs, and attitudes about opioid prescribing and about the use of guideline-based opioid prescribing practices (conservative prescribing, and monitoring for and responding to misuse). Transcripts were thematically analyzed using a modified grounded theory approach. Eighteen HIV treatment providers included 13 physicians, four nurse practitioners, and one physician assistant. They were 62% female, 56% white, and practiced as HIV treatment providers for a mean of 14.6 years. Most reported always or almost always using opioid treatment agreements (56%) and urine drug testing (61%) with their patients on long-term opioid therapy. HIV treatment providers tended to view opioid prescribing for chronic pain within the "HIV paradigm," a set of priorities and principles defined by three key themes: (1) primacy of HIV goals, (2) familiarity with substance use, and (3) the clinician as ally. The HIV paradigm sometimes supported, and sometimes conflicted with, guideline-based opioid prescribing practices. For HIV treatment providers, perceived alignment with the HIV paradigm determined whether and how guideline-based opioid prescribing practices were adopted. For example, the primacy of HIV goals superseded conservative opioid prescribing when providers prescribed opioids with the goal of retaining patients in HIV care. These findings highlight

  9. PUBLIC RELATIONS PROFESSIONALS’ PERCEPTION OF CONFLICT MANAGEMENT AS A MANAGEMENT FUNCTION

    Directory of Open Access Journals (Sweden)

    Tugce Ertem Eray

    2016-12-01

    Full Text Available Conflicts are a part of daily life that people encounter at home, work, and in organizations. It is evident that organizational conflicts are becoming more complex. In this respect, it is important for senior executives not to disregard these conflicts and involve public relations professionals in the conflict management processes. Hence, it is expected that public relations professionals become participants in the strategic planning process and that senior management relies on their experience and talents during the strategic planning process of organizations and resolution of issues. Another definition of public relations has emerged over the past years, even though the recent definitions of public relations focus on developing mutually beneficial relationships between organizations and their publics. Glen T. Cameron from University of Missouri defines public relations as management of conflict and competition strategically for the benefit of one’s own organization and, if possible, mutual benefit of organizations and individuals. It is impossible to disregard the influence of public relations professionals on managing the conflicts between an organization and its peers, and hence it is important to conduct further research on their approach to conflict management. With this motive, research questions have been generated based on the data presented by Professor Kenneth Plowman as a result of his analysis of strategic management of public relations in conflict management. Using the semi-structured interview technique, public relations professionals in Turkey were asked to describe their approach to conflict management.

  10. A tweaking principle for executive control: neuronal circuit mechanism for rule-based task switching and conflict resolution.

    Science.gov (United States)

    Ardid, Salva; Wang, Xiao-Jing

    2013-12-11

    A hallmark of executive control is the brain's agility to shift between different tasks depending on the behavioral rule currently in play. In this work, we propose a "tweaking hypothesis" for task switching: a weak rule signal provides a small bias that is dramatically amplified by reverberating attractor dynamics in neural circuits for stimulus categorization and action selection, leading to an all-or-none reconfiguration of sensory-motor mapping. Based on this principle, we developed a biologically realistic model with multiple modules for task switching. We found that the model quantitatively accounts for complex task switching behavior: switch cost, congruency effect, and task-response interaction; as well as monkey's single-neuron activity associated with task switching. The model yields several testable predictions, in particular, that category-selective neurons play a key role in resolving sensory-motor conflict. This work represents a neural circuit model for task switching and sheds insights in the brain mechanism of a fundamental cognitive capability.

  11. From conflict management to reward-based decision making: actors and critics in primate medial frontal cortex.

    The role of the medial prefrontal cortex (mPFC) and especially the anterior cingulate cortex has been the subject of intense debate for the last decade. A number of theories have been proposed to account for its function. Broadly speaking, some emphasize cognitive control, whereas others emphasize value processing; specific theories concern reward processing, conflict detection, error monitoring, and volatility detection, among others. Here we survey and evaluate them relative to experimental results from neurophysiological, anatomical, and cognitive studies. We argue for a new conceptualization of mPFC, arising from recent computational modeling work. Based on reinforcement learning theory, these new models propose that mPFC is an Actor-Critic system. This system is aimed to predict future events including rewards, to evaluate errors in those predictions, and finally, to implement optimal skeletal-motor and visceromotor commands to obtain reward. This framework provides a comprehensive account of mPFC function, accounting for and predicting empirical results across different levels of analysis, including monkey neurophysiology, human ERP, human neuroimaging, and human behavior.

    2015-03-01

    Full Text Available The paper aims at analysing the connections between film-induced tourism, city-branding and place-based image through the case-study of Naples, particularly deepening the role played by urban policies not only in promoting or sustaining but also in refusing some specific city’s representations. In the first part we will explore this relationship focusing the attention on the changing representations of the city in films and on the changes produced by the urban policies carried out in the phase of so-called Neapolitan Renaissance. The second part will be dedicated to deepen the link between the images of the city conveyed by the media and the touristic sector, emphasizing the role of the official representations and of the Campania Region Film Commission. The third part of the paper will focus on the conflicts involving the urban actors about the existence of a potential link between some negative representations of the periodical crisis of the city (for garbage, organized crime and difficulties in the administrative management and tourist flows. We will argue that the duplicity of representations proposes in a new way the traditional dual image of the Neapolitan cityscape, inspiring by a different notion of “authenticity”.

    Full Text Available Extended Abstract in English Given the increasingly complex nature of conflicts, a corresponding increase of new methods can be observed in Peace and Conflict Studies. At this juncture, metatheories aimed at integrating this labyrinth of diverse methods is becoming necessary. This paper will draft a conceptual proposal, discussing two well-known holistic approaches of mediative conflict management in an integrative context: – The Conflict Management Approach by Prof. Dr. Friedrich Glasl (2004. – The Conflict Transformation Approach (The Transcend Method by Prof. Dr. Johan Galtung (2000. The theoretical assumptions of this paper are based on the integral approach by Ken Wilber (2001 – a highly discussed “Theory of Everything“ that has thus far remained widely ignored in Peace and Conflict Studies, yet. Therefore, it is also of interest to scrutinise the integral approach with regard to its contribution for an integrated Peace and Conflict Studies. The analysis was conducted as follows: 1. Introduction of two holistic Peace and Conflict Studies approaches: a. The Conflict Management Approach by Glasl implies a number of categories and entry points (Ansatzmomente resulting in a complex intervention spectrum. In this regard, the consideration of escalation levels is highly important, integrating perception-oriented (low escalation, emotion-oriented (medium escalation and behaviour-oriented (high escalation measures. The spectrum may be combined with other categories such as conflict type (hot or cold or criteria of conflict analysis (issues, conflict trends etc.. b. The Conflict Transformation Approach by Galtung is characterised by a three-fold schematic, enabling a complex understanding of violence (direct, cultural, structural, conflict (behaviour, assumptions, contradictions and peace (non-violence, empathy, creativity. Moreover, Galtung’s model implies three conflict phases (before, during, after violence as well as five styles of

    Modeling of stress and anxiety in adult zebrafish (Danio rerio) is increasingly utilized in neuroscience research and central nervous system (CNS) drug discovery. Representing the most commonly used zebrafish anxiety models, the novel tank test (NTT) focuses on zebrafish diving in response to potentially threatening stimuli, whereas the light-dark test (LDT) is based on fish scototaxis (innate preference for dark vs. bright areas). Here, we systematically evaluate the utility of these two tests, combining meta-analyses of published literature with comparative in vivo behavioral and whole-body endocrine (cortisol) testing. Overall, the NTT and LDT behaviors demonstrate a generally good cross-test correlation in vivo, whereas meta-analyses of published literature show that both tests have similar sensitivity to zebrafish anxiety-like states. Finally, NTT evokes higher levels of cortisol, likely representing a more stressful procedure than LDT. Collectively, our study reappraises NTT and LDT for studying anxiety-like states in zebrafish, and emphasizes their developing utility for neurobehavioral research. These findings can help optimize drug screening procedures by choosing more appropriate models for testing anxiolytic or anxiogenic drugs.

    There are gender differences in global and domain-specific self-esteem and the incidence of some psychiatric disorders related to self-esteem, suggesting that there are gender differences in the neural basis underlying one's own self-esteem. We investigated gender differences in the brain activity while subjects (14 males and 12 females) performed an implicit self-esteem task, using fMRI. While ventromedial prefrontal cortex (vmPFC) was significantly activated in females, medial and dorsomedial PFC (dmPFC) were activated in males in the incongruent condition (self = negative) compared with the congruent condition (self = positive). Additionally, scores on the explicit self-esteem test were negatively correlated with vmPFC activity in females and positively correlated with dmPFC activity in males. Furthermore, the functional relationships among the regions found by direct gender comparisons were discussed based on the somatic-marker model. These showed that, compared to males, females more firmly store even the incongruent associations as part of their schematic self-knowledge, and such associations automatically activate the neural networks for emotional response and control, in which vmPFC plays a central role. This may explain female cognitive/behavioral traits; females have more tendency to ruminate more often than males, which sometimes results in a prolonged negative affect.

    The current decades are marked not by the development of new molecules for the cure of various diseases but rather the development of new delivery methods for optimum treatment outcome. Nanomedicine is perhaps playing the biggest role in this concern. Nanomedicine offers numerous advantages over conventional drug delivery approaches and is particularly the hot topic in anticancer research. Nanoparticles (NPs) have many unique criteria that enable them to be incorporated in anticancer therapy. This topical review aims to look at the properties and various forms of NPs and their use in anticancer treatment, recent development of the process of identifying new delivery approaches as well as progress in clinical trials with these newer approaches. Although the outcome of cancer therapy can be increased using nanomedicine there are still many disadvantages of using this approach. We aim to discuss all these issues in this review. (review)

  1. Environmental Systems Conflict Resolution

    2017-12-01

    The Graph Model for Conflict Resolution (GMCR) is applied to a real-life groundwater contamination dispute to demonstrate how one can realistically model and analyze the controversy in order to obtain an enhanced understanding and strategic insights for permitting one to make informed decisions. This highly divisive conflict is utilized to explain a rich range of inherent capabilities of GMCR, as well as worthwhile avenues for extensions, which make GMCR a truly powerful decision technology for addressing challenging conflict situations. For instance, a flexible preference elicitation method called option prioritization can be employed to obtain the relative preferences of each decision maker (DM) in the dispute over the states or scenarios which can occur, based upon preference statements regarding the options or courses of actions available to the DMs. Solution concepts, reflecting the way a chess player thinks in terms of moves and counter-moves, are defined to mirror the ways humans may behave under conflict, varying from short to long term thinking. After ascertaining the best outcome that a DM can achieve on his or her own in a conflict, coalition analysis algorithms are available to check if a DM can fare even better via cooperating with others. The ability of GMCR to take into account emotions, strength of preference, attitudes, misunderstandings (referred to as hypergames), and uncertain preferences (unknown, fuzzy, grey and probabilistic) greatly broadens its scope of applicability. Techniques for tracing how a conflict can evolve over time from a status quo state to a final specified outcome, as well as how to handle hierarchical structures, such as when a central government interacts with its provinces or states, further enforces the comprehensive nature of GMCR. Within ongoing conflict research mimicking how physical systems are analyzed, methods for inverse engineering of preferences are explained for determining the preferences required by one or

  4. Right ventrolateral prefrontal cortex mediates individual differences in conflict-driven cognitive control

    Science.gov (United States)

    Egner, Tobias

    2013-01-01

    Conflict adaptation – a conflict-triggered improvement in the resolution of conflicting stimulus or response representations – has become a widely used probe of cognitive control processes in both healthy and clinical populations. Previous functional magnetic resonance imaging (fMRI) studies have localized activation foci associated with conflict resolution to dorsolateral prefrontal cortex (dlPFC). The traditional group-analysis approach employed in these studies highlights regions that are, on average, activated during conflict resolution, but does not necessarily reveal areas mediating individual differences in conflict resolution, because between-subject variance is treated as noise. Here, we employed a complementary approach in order to elucidate the neural bases of variability in the proficiency of conflict-driven cognitive control. We analyzed two independent fMRI data sets of face-word Stroop tasks by using individual variability in the behavioral expression of conflict adaptation as the metric against which brain activation was regressed, while controlling for individual differences in mean reaction time and Stroop interference. Across the two experiments, a replicable neural substrate of individual variation in conflict adaptation was found in ventrolateral prefrontal cortex (vlPFC), specifically, in the right inferior frontal gyrus, pars orbitalis (BA 47). Unbiased regression estimates showed that variability in activity in this region accounted for ~40% of the variance in behavioral expression of conflict adaptation across subjects, thus documenting a heretofore unsuspected key role for vlPFC in mediating conflict-driven adjustments in cognitive control. We speculate that vlPFC plays a primary role in conflict control that is supplemented by dlPFC recruitment under conditions of suboptimal performance. PMID:21568631

  6. Achieving universal health coverage in South Africa through a district health system approach: conflicting ideologies of health care provision.

    Fusheini, Adam; Eyles, John

    2016-10-07

    Universal Health Coverage (UHC) has emerged as a major goal for health care delivery in the post-2015 development agenda. It is viewed as a solution to health care needs in low and middle countries with growing enthusiasm at both national and global levels. Throughout the world, however, the paths of countries to UHC have differed. South Africa is currently reforming its health system with UHC through developing a national health insurance (NHI) program. This will be practically achieved through a decentralized approach, the district health system, the main vehicle for delivering services since democracy. We utilize a review of relevant documents, conducted between September 2014 and December 2015 of district health systems (DHS) and UHC and their ideological underpinnings, to explore the opportunities and challenges, of the district health system in achieving UHC in South Africa. Review of data from the NHI pilot districts suggests that as South Africa embarks on reforms toward UHC, there is a need for a minimal universal coverage and emphasis on district particularity and positive discrimination so as to bridge health inequities. The disparities across districts in relation to health profiles/demographics, health delivery performance, management of health institutions or district management capacity, income levels/socio-economic status and social determinants of health, compliance with quality standards and above all the burden of disease can only be minimised through positive discrimination by paying more attention to underserved and disadavantaged communities. We conclude that in South Africa the DHS is pivotal to health reform and UHC may be best achieved through minimal universal coverage with positive discrimination to ensure disparities across districts in relation to disease burden, human resources, financing and investment, administration and management capacity, service readiness and availability and the health access inequalities are consciously

    Full Text Available The prevalence of social networks and the excessive use of them by couples have had a significant impact on various aspects of their lives. The aim of this study was to investigate the role of social networks in the formation of narcissism, perception of social interaction and marital conflicts in couples who use these social networks. The study design was correlational and the statistical population included couples of Zanjan city who use social networks. 120 couples which widely used social networks were selected by random sampling. The questionnaires of Internet Addiction (Young, 1998, Narcissistic Personality (Ames and et al, 2006, Perception of Social Interaction (Glass, 1994 and Marital Conflict (Sanaei, 2000 were used. Pearson correlation coefficient and Regression were used for data analysis. This study showed that there is a significant negative relationship between the use of social networks with perception of social interaction, and a significant positive relationship between the use of social networks with narcissism and marital conflicts (P<0/01. Also narcissism has a significant positive relationship with marital conflicts, and a significant negative relationship with perception of social interaction (P<0/01. Social networks have a negative effect on couple's relationship and their feelings towards each other, as well as strengthening narcissism, which can cause communication problems, decreased positive feelings of couples towards each other and marital conflicts.

    Aquilino, M Lober; Lowe, J B

    2004-02-01

    Tobacco production, distribution, and use are international issues with significant health and economic implications. This paper provides an overview of the effective approaches to tobacco control including decreasing demand for tobacco products through taxation, consumer education, research, bans on advertising and promotion, warning labels, and restrictions on public smoking. The effectiveness of reducing the supply of tobacco products through prohibition, restrictions on youth access, crop substitution, trade restrictions, and control of smuggling, will also be discussed. Decreasing smoking, particularly among young people, by preventing or delaying initiation, preventing regular use, and increasing cessation through behavioural approaches for all ages is reviewed. Cessation methods including pharmacological approaches, 'quitlines', Internet programmes, and the targeting of specific populations are discussed. Internet availability of tobacco products and sustainability of current efforts are presented as continuing challenges to tobacco control.

    Full Text Available BackgroundIt has been observed that trait anxiety easily leads to conflict maladaptation under conflict circumstances. However, it remains unclear whether the precise neural mechanisms underlying the effects of high trait anxiety (HTA on cognitive control are consistent in high trait anxious individuals, with and without anxiety disorders.MethodsThe present study recruited 29 healthy volunteers with low trait anxiety (LTA, 37 healthy volunteers with HTA, and 23 patients with generalized anxiety disorder (GAD. All participants completed demographic information and self-report measures of trait anxiety and depression. Then, they performed the emotional flanker task with event-related potentials (ERPs recorded.ResultsBehavioral data manifested that, relative to LTA individuals, GAD patients displayed prolonged response times and increased error rates, while HTA individuals showed intact response times and accuracies. Event-related potential (ERP data revealed that HTA individuals exhibited a trend toward more negative N2 amplitudes for conflict detection. By contrast, both HTA and GAD individuals displayed decreased P3 amplitudes for conflict resolution. ERP results indicated that both HTA and GAD individuals exhibited conflict maladaptation on the N2 amplitude. Correlation analyses also showed that the increased anxiety symptoms were associated with longer reaction times, more error rates, lower P3 amplitudes, and more perturbations in conflict adaptation on reaction times and N2 amplitudes.ConclusionOur results demonstrated a severely impaired cognitive control in GAD patients while a moderately impaired cognitive control in HTA individuals. Trait anxiety can indeed serve as a predominant factor at the onset and in the maintenance of GAD. Therefore, the trait anxiety reducing strategies may provide significant therapeutic gains.

  13. Combination of Evidence with Different Weighting Factors: A Novel Probabilistic-Based Dissimilarity Measure Approach

    Mengmeng Ma

    2015-01-01

    Full Text Available To solve the invalidation problem of Dempster-Shafer theory of evidence (DS with high conflict in multisensor data fusion, this paper presents a novel combination approach of conflict evidence with different weighting factors using a new probabilistic dissimilarity measure. Firstly, an improved probabilistic transformation function is proposed to map basic belief assignments (BBAs to probabilities. Then, a new dissimilarity measure integrating fuzzy nearness and introduced correlation coefficient is proposed to characterize not only the difference between basic belief functions (BBAs but also the divergence degree of the hypothesis that two BBAs support. Finally, the weighting factors used to reassign conflicts on BBAs are developed and Dempster’s rule is chosen to combine the discounted sources. Simple numerical examples are employed to demonstrate the merit of the proposed method. Through analysis and comparison of the results, the new combination approach can effectively solve the problem of conflict management with better convergence performance and robustness.

    Unlike with Eimeria species infecting chickens, specific identification and nomenclature of Eimeria species infecting turkeys is complicated, and in the absence of molecular data, imprecise. In an attempt to reconcile contradictory data reported on oocyst morphometrics and biological descriptions of various Eimeria species infecting turkey, we established single oocyst derived lines of 5 important Eimeria species infecting turkeys, Eimeria meleagrimitis (USMN08-01 strain), Eimeria adenoeides (Guelph strain), Eimeria gallopavonis (Weybridge strain), Eimeria meleagridis (USAR97-01 strain), and Eimeria dispersa (Briston strain). Short portions (514 bp) of mitochondrial cytochrome c oxidase subunit I gene (mt COI) from each were amplified and sequenced. Comparison of these sequences showed sufficient species-specific sequence variation to recommend these short mt COI sequences as species-specific markers. Uniformity of oocyst features (dimensions and oocyst structure) of each pure line was observed. Additional morphological features of the oocysts of these species are described as useful for the microscopic differentiation of these Eimeria species. Combined molecular and morphometric data on these single species lines compared with the original species descriptions and more recent data have helped to clarify some confusing, and sometimes conflicting, features associated with these Eimeria spp. For example, these new data suggest that the KCH and KR strains of E. adenoeides reported previously represent 2 distinct species, E. adenoeides and E. meleagridis, respectively. Likewise, analysis of the Weybridge strain of E. adenoeides, which has long been used as a reference strain in various studies conducted on the pathogenicity of E. adenoeides, indicates that this coccidium is actually a strain of E. gallopavonis. We highly recommend mt COI sequence-based genotyping be incorporated into all studies using Eimeria spp. of turkeys to confirm species identifications and so

    2011-01-01

    Full Text Available This paper summarizes various integrated methodological approaches for studying Customary Management for the purpose of designing hybrid CM-Ecosystem-Based Management (EBM systems in Oceania. Using marine conservation in the Western Solomon Islands as an example, the paper illustrates various interdisciplinary human ecological methods that can assist in designing hybrid conservation programs. The study of human-environmental interactions from a socio-ecological perspective allows us to discern people's understanding of their immediate environment, differential forms of local resource governance and use (e.g., sea tenure and foraging strategies, and existing conflicts between various stakeholders, among other social and ecological factors. More generally, the paper shows how coupled studies of natural and social processes can foster management regimes that are more adaptive and effective and that move toward holistic, ecosystem-based marine conservation in the Pacific Island region.

    Jones, Hannah M; Mayawala, Kapil; Poulin, Patrick

    2013-04-01

    Physiologically based pharmacokinetic (PBPK) models are built using differential equations to describe the physiology/anatomy of different biological systems. Readily available in vitro and in vivo preclinical data can be incorporated into these models to not only estimate pharmacokinetic (PK) parameters and plasma concentration-time profiles, but also to gain mechanistic insight into compound properties. They provide a mechanistic framework to understand and extrapolate PK and dose across in vitro and in vivo systems and across different species, populations and disease states. Using small molecule and large molecule examples from the literature and our own company, we have shown how PBPK techniques can be utilised for human PK and dose prediction. Such approaches have the potential to increase efficiency, reduce the need for animal studies, replace clinical trials and increase PK understanding. Given the mechanistic nature of these models, the future use of PBPK modelling in drug discovery and development is promising, however some limitations need to be addressed to realise its application and utility more broadly.

  3. Promoting the freedom of thought of mental health service users: Nussbaum's capabilities approach meets values-based practice.

    Science.gov (United States)

    Stenlund, Mari

    2017-08-09

    This article clarifies how the freedom of thought as a human right can be understood and promoted as a right of mental health service users, especially people with psychotic disorder, by using Martha Nussbaum's capabilities approach and Fulford's and Fulford et al 's values-based practice. According to Nussbaum, freedom of thought seems to primarily protect the capability to think, believe and feel. This capability can be promoted in the context of mental health services by values-based practice. The article points out that both Nussbaum's approach and values-based practice recognise that people's values differ. The idea of involving different actors and service users in mental healthcare is also common in both Nussbaum's approach and values-based practice. However, there are also differences in that values-based practice relies on a 'good process' in decision-making, whereas the capabilities approach is oriented towards a 'right outcome'. However, since process and outcome are linked with each other, these two approaches do not necessarily conflict despite this difference. The article suggests that absolute rights are possible within the two approaches. It also recognises that the capabilities approach, values-based practice and human rights approach lean on liberal values and thus can be combined at least in liberal societies. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Business rules and business processes are essential artifacts in defining the requirements of a software system. Business processes capture business behavior, while rules connect processes and thus control processes and business behavior. Traditionally, rules are scattered inside application code. This approach makes it very difficult to change rules and shorten the life cycle of the software system. Because rules change more quickly than the application itself, it is desirable to externalize...

    Mandeep K. Dhami

    2008-10-01

    Full Text Available Using Brunswik's (1952 lens model framework, Hammond (1965 proposed interpersonal conflict theory to explain the nature, source, and resolution of disagreement or ``cognitive conflict'' between parties performing judgment tasks. An early review by Brehmer (1976 highlighted the potential of this approach in, for example, understanding the structure of cognitive conflicts, and the effect of task and person variables on judgment policy change and conflict resolution. However, our bibliographic and content reviews from 1976 to the present day demonstrate that research on cognitive conflict using the lens model has declined sharply, while research on ``task conflict'' has grown dramatically. There has also been a shift to less theoretical precision and methodological rigor. We discuss possible reasons for these developments, and suggest ways in which lens model research on cognitive conflict can be revitalized by borrowing from recent theoretical and methodological advances in the field of judgment and decision making.

    Full Text Available Pela Gandong which is believed by Ambonese for its propitiational value is in fact failed to prevent horizontal conflict that victimized a big number of life and financial damages. However, Wayame villagem is found to survive from those conflicts, and the community of this village, comprising of Islam and Christian religious group, succeeds to maintain harmonious relation. The research aims at, first, describing the perception of Wayamae village community to Pela Gandong in the post-conflict period; second, analyzing the cultural competence of pela Gandong in conflict resolution in the era of technology. This research employed qualitative method, involving in-field data gathering based on official report, digging out information from the resource persons who were directly witnessing the conflict when it occured and other references obtained through Forum Group Discussion (FGD. An analysis was performed to seek answer concerning on how the community of Wayame village viewed Pela Gandong in post-conflict period, how it is – as a local wisdom – maintained in the middle of changing and how Pela Gandong was revitalized. Research showed that Pela Gandong was maintained by involving all elements such as customary community and the government. Pela Gandong grew as the icon of Ambonese society in settling conflicts by raising awareness that they are Eastern people, collectivistic in nature, and place kinship into priority.

  15. Antirandom Testing: A Distance-Based Approach

    Directory of Open Access Journals (Sweden)

    Shen Hui Wu

    2008-01-01

    Full Text Available Random testing requires each test to be selected randomly regardless of the tests previously applied. This paper introduces the concept of antirandom testing where each test applied is chosen such that its total distance from all previous tests is maximum. This spans the test vector space to the maximum extent possible for a given number of vectors. An algorithm for generating antirandom tests is presented. Compared with traditional pseudorandom testing, antirandom testing is found to be very effective when a high-fault coverage needs to be achieved with a limited number of test vectors. The superiority of the new approach is even more significant for testing bridging faults.

    shortcoming in preventing impasses is a need to have a priori information on the future demand for resources, and it is not always possible.One of ways to "struggle" against impasses when there is no a priori information on the process demand for resources is to detect deadlocks. Detection of impasses (without leading to their resolution yet is a periodical use of the algorithm which checks current distribution of resources to reveal whether there is an impasse and if it exists what processes are involved in it.The work objective is to develop methods and algorithms allowing us to minimize losses because of impasses in CS using the optimum strategy of conflict resolution. The offered approach is especially effective to eliminate deadlocks in management (control computer systems having a fixed set of programmes.The article offers a developed efficient strategy of the information processes management in multiprocessing CS, which detects and prevents impasses. The strategy is based on allocation of indivisible resources to computing processes so that losses caused by conflicts are minimized. The article studies a multi-criterion problem of indivisible resources allocation to the processes, with the optimality principle expressed by the known binary relation over set of average vectors of penalties for conflicts in each of resources. It is shown that sharing a decision theory tool and a classical one allows more efficient problem solution to eliminate deadlock. The feature of suggesting effective methods and algorithms to eliminate deadlocks is that they can be used in CS development and operation in real time. The article-given example shows that the proposed method and algorithm for the impasse resolution in multiprocessing CS are capable and promising.The offered method and algorithm provide reducing the average number of CS conflicts by 30-40 %.

  18. Context matters (but how and why?) A hypothesis-led literature review of performance based financing in fragile and conflict-affected health systems.

    Bertone, Maria Paola; Falisse, Jean-Benoît; Russo, Giuliano; Witter, Sophie

    2018-01-01

    Performance-based financing (PBF) schemes have been expanding rapidly across low and middle income countries in the past decade, with considerable external financing from multilateral, bilateral and global health initiatives. Many of these countries have been fragile and conflict-affected (FCAS), but while the influence of context is acknowledged to be important to the operation of PBF, there has been little examination of how it affects adoption and implementation of PBF. This article lays out initial hypotheses about how FCAS contexts may influence the adoption, adaption, implementation and health system effects of PBF. These are then interrogated through a review of available grey and published literature (140 documents in total, covering 23 PBF schemes). We find that PBF has been more common in FCAS contexts, which were also more commonly early adopters. Very little explanation of the rationale for its adoption, in particular in relation with the contextual features, is given in programme documents. However, there are a number of factors which could explain this, including the greater role of external actors and donors, a greater openness to institutional reform, and lower levels of trust within the public system and between government and donors, all of which favour more contractual approaches. These suggest that rather than emerging despite fragility, conditions of fragility may favour the rapid emergence of PBF. We also document few emerging adaptations of PBF to humanitarian settings and limited evidence of health system effects which may be contextually driven, but these require more in-depth analysis. Another area meriting more study is the political economy of PBF and its diffusion across contexts.

  2. S-variable approach to LMI-based robust control

    CERN Document Server

    Ebihara, Yoshio; Arzelier, Denis

    2015-01-01

    This book shows how the use of S-variables (SVs) in enhancing the range of problems that can be addressed with the already-versatile linear matrix inequality (LMI) approach to control can, in many cases, be put on a more unified, methodical footing. Beginning with the fundamentals of the SV approach, the text shows how the basic idea can be used for each problem (and when it should not be employed at all). The specific adaptations of the method necessitated by each problem are also detailed. The problems dealt with in the book have the common traits that: analytic closed-form solutions are not available; and LMIs can be applied to produce numerical solutions with a certain amount of conservatism. Typical examples are robustness analysis of linear systems affected by parametric uncertainties and the synthesis of a linear controller satisfying multiple, often  conflicting, design specifications. For problems in which LMI methods produce conservative results, the SV approach is shown to achieve greater accuracy...

    Full Text Available Aims: Oppositional defiant disorder that occurs in pre-school or early school-age children and in pre-adolescent stage has a widespread impact on the child, family, teachers and society. The aim of the study was to determine the effect of mindful parenting education program on reducing the anxiety and parent-child conflict and increasing the self-agency of parenting in mothers who have oppositional defiant disorder daughters. Materials & Methods: This semi-experimental study with a pretest-posttest control group was performed during 2015-2016 academic year in 34 mothers of primary school girl students of Noorabad City, Iran, who were suffering from oppositional defiant disorder. The samples were selected by purposeful clustering method and were randomly divided into 2 test and control groups (each had 17 members. The research tools were Child Behavioral Logbook and Teacher Report Form, Beck Anxiety Inventory, Conflict Strategy and Parent Self-efficacy Questionnaires. Mindfulness-based parenting educational program was conducted for the experimental group one 2-hour session a week for 2 months. Data were analyzed by SPSS 23 software using MANCOVA test. Findings: The average of total anxiety, parent-child conflict and parental self-efficacy scores were higher in the experimental group in posttest. After controlling the effect of pre-test scores, there were significant differences between the test and control groups in terms of all variables (p<0.001. Conclusion: Mindfulness-based parenting educational program reduces the anxiety and parent-child conflict and increases the parental self-efficacy in mothers with oppositional defiant disorder.

    Full Text Available The present article envisages presenting the conciliation as a resolution procedure for the conflicts of interests/collective labour conflicts. The conciliation was stipulated as a resolution procedure for the conflicts of interests/collective labour conflicts even from the first acts that regulated this domain, being foreseen as a mandatory phase within the process of solving this type of conflicts. The subject of conciliation was approached before within the doctrine, from this juridical institution development point of view, the used research methods being the observation and the comparative analysis. The legislator adapted the procedure for the resolution of conflicts of interests/ collective labour conflicts in accordance with the social and economic development of the labour relations and identified other means of resolution, such as the mediation, the arbitrage or the strike, when the conciliation didn’t lead to the end of the conflict. The present paper aims is to realize an assessment over the historical development of the labour conflicts conciliation and to draw up a study on the statistical data concerning these conflicts. The study may be used within the research activity, its contribution being set up by the updated presentation of the statistical data and on the legislation within the field of labour conflicts conciliation.

    2014-06-01

    Full Text Available Increasing food production without compromising biodiversity is one of the great challenges for humanity. The aims of my thesis were to define spatial priorities for biodiversity conservation and to evaluate conservation conflicts considering agricultural expansion in the 21st century. I also tested the effect of globalizing conservation efforts on both food production and biodiversity conservation. I found spatial conflicts between biodiversity conservation and agricultural expansion. However, incorporating agricultural expansion data into the spatial prioritization process can significantly alleviate conservation conflicts, by reducing spatial correlation between the areas under high impact of agriculture and the priority areas for conservation. Moreover, developing conservation blueprints at the global scale, instead of the usual approach based on national boundaries, can benefit both food production and biodiversity. Based on these findings I conclude that the incorporation of agricultural expansion as a key component for defining global conservation strategies should be added to the list of solutions for our cultivated planet.

    Full Text Available The diagnosis method for a weak-fault model with only normal behaviors of each component has evolved over decades. However, many systems now demand a strong-fault models, the fault modes of which have specific behaviors as well. It is difficult to diagnose a strong-fault model due to its non-monotonicity. Currently, diagnosis methods usually employ conflicts to isolate possible fault and the process can be expedited when some observed output is consistent with the model’s prediction where the consistency indicates probably normal components. This paper solves the problem of efficiently diagnosing a strong-fault model by proposing a novel Logic-based Truth Maintenance System (LTMS with two search approaches based on conflict and consistency. At the beginning, the original a strong-fault model is encoded by Boolean variables and converted into Conjunctive Normal Form (CNF. Then the proposed LTMS is employed to reason over CNF and find multiple minimal conflicts and maximal consistencies when there exists fault. The search approaches offer the best candidate efficiency based on the reasoning result until the diagnosis results are obtained. The completeness, coverage, correctness and complexity of the proposals are analyzed theoretically to show their strength and weakness. Finally, the proposed approaches are demonstrated by applying them to a real-world domain—the heat control unit of a spacecraft—where the proposed methods are significantly better than best first and conflict directly with A* search methods.

    Our approach is based on a tri-partite method of integrating psychodynamic hypotheses, cognitive subliminal processes, and psychophysiological alpha power measures. We present ten social phobic subjects with three individually selected groups of words representing unconscious conflict, conscious symptom experience, and Osgood Semantic negative valence words used as a control word group. The unconscious conflict and conscious symptom words, presented subliminally and supraliminally, act as primes preceding the conscious symptom and control words presented as supraliminal targets. With alpha power as a marker of inhibitory brain activity, we show that unconscious conflict primes, only when presented subliminally, have a unique inhibitory effect on conscious symptom targets. This effect is absent when the unconscious conflict primes are presented supraliminally, or when the target is the control words. Unconscious conflict prime effects were found to correlate with a measure of repressiveness in a similar previous study (Shevrin et al., 1992, 1996). Conscious symptom primes have no inhibitory effect when presented subliminally. Inhibitory effects with conscious symptom primes are present, but only when the primes are supraliminal, and they did not correlate with repressiveness in a previous study (Shevrin et al., 1992, 1996). We conclude that while the inhibition following supraliminal conscious symptom primes is due to conscious threat bias, the inhibition following subliminal unconscious conflict primes provides a neurological blueprint for dynamic repression: it is only activated subliminally by an individual's unconscious conflict and has an inhibitory effect specific only to the conscious symptom. These novel findings constitute neuroscientific evidence for the psychoanalytic concepts of unconscious conflict and repression, while extending neuroscience theory and methods into the realm of personal, psychological meaning.

    Full Text Available In this paper, we consider the theoretical framework for creating an advanced training course for professionals working in various organizations whose functional duties include activities aimed at managing conflict situations occurring within the organization. The article also considers such problem concepts as: essence and causes of conflicts, types of conflicts in the organization; organizational, psychological, sociological and cultural ways of managing conflicts in the organization. The proposed theoretical model of advanced professional training is constructed within the framework of the competence approach which, in this case, is based on the notion that a participant in the program should master a certain set of special competencies that include knowledge, skills and abilities necessary for the effective process management of various conflict situations.

    2017-09-01

    Full Text Available Based on the Piagetian perspective, this qualitative and quantitative study sought to investigate the causes of conflicts among primary school students. Thirty children aged 8 and 9 from a primary school, selected according to the criterion of convenience. Data were collected through 23 sessions of observation of the interactions between the children in different moments of the school routine until the saturation of the data, criterion chosen to leave the field. In some situations, it was necessary to have an informal conversation with the participants to better understand the conflict. The results indicated that the main cause of conflict among students was teasing, annoying behavior and physical dispute. It discusses the influence of cognitive, affective and moral development, as well as the cultural aspects that influence the experience of the conflict. It is recommended the implementation of educational interventions that, in addition to approaching conflicts with students, invest in strategies for valuing ethical coexistence.

    Full Text Available Dynamically positioned vessels, used by offshore industry, use not only satellite navigation but also different positioning systems, often referred to as reference' systems. Most of them use multiple technical devices located outside the vessel which creates some problems with their accessibility and performance. In this paper, a basic concept of reference system independent from any external device is presented, basing on hydroacoustics and Simultaneous Localization and Mapping (SLAM method. Theoretical analysis of its operability is also performed.

    Full Text Available Tuberculosis, commonly known as TB, is the second most fatal infectious disease after AIDS, caused by bacterium called Mycobacterium tuberculosis. Prolonged treatment, high pill burden, low compliance, and stiff administration schedules are factors that are responsible for emergence of MDR and XDR cases of tuberculosis. Till date, only BCG vaccine is available which is ineffective against adult pulmonary TB, which is the most common form of disease. Various unique antibodies have been developed to overcome drug resistance, reduce the treatment regimen, and elevate the compliance to treatment. Therefore, we need an effective and robust system to subdue technological drawbacks and improve the effectiveness of therapeutic drugs which still remains a major challenge for pharmaceutical technology. Nanoparticle-based ideology has shown convincing treatment and promising outcomes for chronic infectious diseases. Different types of nanocarriers have been evaluated as promising drug delivery systems for various administration routes. Controlled and sustained release of drugs is one of the advantages of nanoparticle-based antituberculosis drugs over free drug. It also reduces the dosage frequency and resolves the difficulty of low poor compliance. This paper reviews various nanotechnology-based therapies which can be used for the treatment of TB.

    Full Text Available The author grounds her research and the latter analysis on continually conducted daily press-clipping of seven main printed daily newspapers and two main electronic media in Serbia, within the three years period (2009 - 2011. An analysis of media reports on gender based violence, with particular focus on the most frequent domestic violence cases within the two years period, 2010 to 2011 is presented. As the best of media reports on gender based violence, the author stressed out its „whistle blower“ role - media are the main source of information on cases, dimensions and forms of gender based violence. Also the worse moments of media reporting in the mentioned period are presented - when the violence was justified or when reality is deformed by presenting these cases as romantic love stories. For example, in 2010 the worst was reporting on the „Pajčin/Kapisoda“ case, while in 2011 it was the „Ponjiger“ case. In the end, the author also warned on the worrysome fact of sudden dissapearance of media reports on partners’ murdering their wives after the last such report published in mid-october 2011, which could mean that now we have a new problem of diminished freedom of media.

  2. Conflict and human African trypanosomiasis.

    2011-02-01

    Human African Trypanosomiasis (HAT) has reemerged in sub-Saharan Africa as a disease of major public health importance. The success of HAT elimination in sub-Saharan Africa is subject to the feasibility of controlling, eliminating, or mitigating the determinants of incidence in affected countries. Conflict has been widely recognized and cited as a contributing factor to the resurgence of HAT in many countries, as well as to continuing HAT incidence in politically unstable and resource-poor regions. Despite extensive anecdotal and qualitative recognition of the role of conflict, there has been no quantitative research of this topic at the population level in affected African countries. We characterize the qualitative and quantitative associations between HAT incidence and conflict-related processes in HAT-affected African countries over the past 30 years. HAT and conflict-related data were collected for 35 affected countries in sub-Saharan Africa for the years 1976-2004. Descriptive and univariate inferential statistics, as well as negative binomial regression modeling, are used to assess the associations between HAT and conflict. A space-time scan statistic is used to identify significant incidence clusters. Clusters of HAT incidence over the past 30 years have predominantly coincided with periods of conflict or socio-political instability. HAT cases occurred significantly more often in countries and during years with conflict, high political terror, and internationalized civil war. The results indicate a lag period between the start of conflict events and a peak in incidence of approximately 10 years. We recommend explicit consideration and quantification of socio-political measures such as conflict and terror indices in GIS (Geographic Information Systems)-based risk assessments for HAT policy and intervention.

    Four alternative risk-based approaches to Technical Specifications are identified. These are: a Probabilistic Risk Assessment (PRA) oriented approach; a reliability goal-oriented approach; an approach based on configuration control; a data-oriented approach. Based on preliminary results, the PRA-oriented approach, which has been developed further than the other approaches, seems to offer a logical, quantitative basis for setting Allowed Outage Times (AOTs) and Surveillance Test Intervals (STIs) for some plant components and systems. The most attractive feature of this approach is that it directly links the AOTs and STIs with the risk associated with the operation of the plant. This would focus the plant operator's and the regulatory agency's attention on the most risk-significant components of the plant. A series of practical issues related to the level of detail and content of the plant PRAs, requirements for the review of these PRAs, and monitoring cf the plant's performance by the regulatory agency must be resolved before the approach could be implemented. Future efforts will examine the other three approaches and their practicality before firm conclusions are drawn regarding the viability of any of these approaches

    2016-11-01

    To examine the effects of work-family-school role conflicts and role-related social support (RRSS) on burnout of nurses pursuing an advanced degree. A predictive correlational cross-sectional study design was used. Nurses were found to be a high-risk group for burnout, even more so among nurses pursuing an advanced degree. When nurses with a professional career marry and decide to become students, inter-role conflicts and burnout are possible outcomes of the resulting multiple roles. Using convenience sampling, data were collected from October 2011-May 2012. A questionnaire about work-family-school role conflicts, RRSS, burnout and general information was completed by 286 nurses pursuing an advanced degree at 12 hospitals in Korea. Data were analysed using SPSS and structural equation modelling with the Analysis of Moment Structures program. The proposed model provided a good fit to the obtained data. Work-family-school role conflicts and social support exerted significant effects on burnout. Role-related social support was found to play a partial mediating role between work-family-school role conflicts and burnout. The findings of this study imply that RRSS significantly directly and indirectly influences burnout among the nurses pursuing an advanced degree. It is necessary for nursing managers to consider implementing family- and school-friendly policies (e.g. flexible work schedules) to help nurses to manage their multiple roles and thereby decrease their burnout rate. © 2016 John Wiley & Sons Ltd.

  11. A hybrid agent-based approach for modeling microbiological systems.

    Guo, Zaiyi; Sloot, Peter M A; Tay, Joc Cing

    2008-11-21

    Models for systems biology commonly adopt Differential Equations or Agent-Based modeling approaches for simulating the processes as a whole. Models based on differential equations presuppose phenomenological intracellular behavioral mechanisms, while models based on Multi-Agent approach often use directly translated, and quantitatively less precise if-then logical rule constructs. We propose an extendible systems model based on a hybrid agent-based approach where biological cells are modeled as individuals (agents) while molecules are represented by quantities. This hybridization in entity representation entails a combined modeling strategy with agent-based behavioral rules and differential equations, thereby balancing the requirements of extendible model granularity with computational tractability. We demonstrate the efficacy of this approach with models of chemotaxis involving an assay of 10(3) cells and 1.2x10(6) molecules. The model produces cell migration patterns that are comparable to laboratory observations.

  12. INDIVIDUAL BASED MODELLING APPROACH TO THERMAL ...

    Science.gov (United States)

    Diadromous fish populations in the Pacific Northwest face challenges along their migratory routes from declining habitat quality, harvest, and barriers to longitudinal connectivity. Changes in river temperature regimes are producing an additional challenge for upstream migrating adult salmon and steelhead, species that are sensitive to absolute and cumulative thermal exposure. Adult salmon populations have been shown to utilize cold water patches along migration routes when mainstem river temperatures exceed thermal optimums. We are employing an individual based model (IBM) to explore the costs and benefits of spatially-distributed cold water refugia for adult migrating salmon. Our model, developed in the HexSim platform, is built around a mechanistic behavioral decision tree that drives individual interactions with their spatially explicit simulated environment. Population-scale responses to dynamic thermal regimes, coupled with other stressors such as disease and harvest, become emergent properties of the spatial IBM. Other model outputs include arrival times, species-specific survival rates, body energetic content, and reproductive fitness levels. Here, we discuss the challenges associated with parameterizing an individual based model of salmon and steelhead in a section of the Columbia River. Many rivers and streams in the Pacific Northwest are currently listed as impaired under the Clean Water Act as a result of high summer water temperatures. Adverse effec

    2013-01-01

    Full Text Available This work presents an efficient solution using computer algebra system to perform linear temporal properties verification for synchronous digital systems. The method is essentially based on both Groebner bases approaches and symbolic simulation. A mechanism for constructing canonical polynomial set based symbolic representations for both circuit descriptions and assertions is studied. We then present a complete checking algorithm framework based on these algebraic representations by using Groebner bases. The computational experience result in this work shows that the algebraic approach is a quite competitive checking method and will be a useful supplement to the existent verification methods based on simulation.

  16. Assessing Acid-Base Status: Physiologic Versus Physicochemical Approach.

    Science.gov (United States)

    Adrogué, Horacio J; Madias, Nicolaos E

    2016-11-01

    The physiologic approach has long been used in assessing acid-base status. This approach considers acids as hydrogen ion donors and bases as hydrogen ion acceptors and the acid-base status of the organism as reflecting the interaction of net hydrogen ion balance with body buffers. In the physiologic approach, the carbonic acid/bicarbonate buffer pair is used for assessing acid-base status and blood pH is determined by carbonic acid (ie, Paco 2 ) and serum bicarbonate levels. More recently, the physicochemical approach was introduced, which has gained popularity, particularly among intensivists and anesthesiologists. This approach posits that the acid-base status of body fluids is determined by changes in the dissociation of water that are driven by the interplay of 3 independent variables: the sum of strong (fully dissociated) cation concentrations minus the sum of strong anion concentrations (strong ion difference); the total concentration of weak acids; and Paco 2 . These 3 independent variables mechanistically determine both hydrogen ion concentration and bicarbonate concentration of body fluids, which are considered as dependent variables. Our experience indicates that the average practitioner is familiar with only one of these approaches and knows very little, if any, about the other approach. In the present Acid-Base and Electrolyte Teaching Case, we attempt to bridge this knowledge gap by contrasting the physiologic and physicochemical approaches to assessing acid-base status. We first outline the essential features, advantages, and limitations of each of the 2 approaches and then apply each approach to the same patient presentation. We conclude with our view about the optimal approach. Copyright © 2016 National Kidney Foundation, Inc. All rights reserved.

    Teaching nuclear power requires an expert to communicate a significant number of abstract concepts from diverse disciplines, and assemble these into a larger intellectual framework for the students. Scholarly education research, particularly in individual science disciplines, has provided significant advances in teaching core subject material by breaking away from traditional lecturing. Thus far, however,little work has applied these results to introductory nuclear power classes. This paper explores a method of engaging introductory nuclear students deeply by using a combination of Socratic and mastery methods of teaching. Students develop conceptual understanding of the material through the group work and the use of diverse resources, including textbooks, online references, and computer models that encourage free exploration of these concepts. Marks have improved considerably, and students engage with the material at a significantly deeper level than in previous lecture-based iterations of this course. (author)

    2015-01-01

    Radiotherapy requires competent professional staff to ensure safe and effective patient treatment and management. There is a need to provide guidelines that recommend appropriate staffing levels to support the initiation of new services as well as the expansion or upgrade of existing services as even simple upgrades or replacement of existing equipment may have a significant impact on staffing needs. Similarly, the introduction of education and training programmes will require staffing adjustments. A calculation algorithm was developed to predict staffing levels based on the inputs that are known or can be easily estimated. This publication complements other IAEA publications used to support the initiation of basic radiation medicine services including Setting up a Radiotherapy Programme: Clinical, Medical Physics, Radiation Protection and Safety Aspects, published in 2008

    2015-01-01

    Our previous work characterized altered cerebral activations during cognitive control in individuals with alcohol dependence (AD). A hallmark of cognitive control is the ability to anticipate changes and adjust behavior accordingly. Here, we employed a Bayesian model to describe trial-by-trial anticipation of the stop signal and modeled fMRI signals of conflict anticipation in a stop signal task. Our goal is to characterize the neural correlates of conflict anticipation and its relationship to response inhibition and alcohol consumption in AD. Twenty-four AD and 70 age and gender matched healthy control individuals (HC) participated in the study. fMRI data were pre-processed and modeled with SPM8. We modeled fMRI signals at trial onset with individual events parametrically modulated by estimated probability of the stop signal, p(Stop), and compared regional responses to conflict anticipation between AD and HC. To address the link to response inhibition, we regressed whole-brain responses to conflict anticipation against the stop signal reaction time (SSRT). Compared to HC (54/70), fewer AD (11/24) showed a significant sequential effect - a correlation between p(Stop) and RT during go trials - and the magnitude of sequential effect is diminished, suggesting a deficit in proactive control. Parametric analyses showed decreased learning rate and over-estimated prior mean of the stop signal in AD. In fMRI, both HC and AD responded to p(Stop) in bilateral inferior parietal cortex and anterior pre-supplementary motor area, although the magnitude of response increased in AD. In contrast, HC but not AD showed deactivation of the perigenual anterior cingulate cortex (pgACC). Furthermore, deactivation of the pgACC to increasing p(Stop) is positively correlated with the SSRT in HC but not AD. Recent alcohol consumption is correlated with increased activation of the thalamus and cerebellum in AD during conflict anticipation. The current results highlight altered proactive

    This article presents a review of arts-based and creative approaches to dementia care as an alternative to antipsychotic medications. While use of antipsychotics may be appropriate for some people, the literature highlights the success of creative approaches and the benefits of their lack of negative side effects associated with antipsychotics. The focus is the use of biographical approaches, music, dance and movement to improve wellbeing, enhance social networks, support inclusive practice and enable participation. Staff must be trained to use these approaches. A case study is presented to demonstrate how creative approaches can be implemented in practice and the outcomes that can be expected when used appropriately.

  4. Aiming at a Moving Target: Theoretical and Methodological Considerations in the Study of Intraindividual Goal Conflict between Personal Goals.

    Gorges, Julia; Grund, Axel

    2017-01-01

    Multiple-goal pursuit and conflict between personal life-defining goals can be considered part of everyday business in most individuals' lives. Given the potentially detrimental effects of goal conflict-for example, impaired well-being or poor performance-the literature on goal conflict is surprisingly scattered due to heterogeneous methodological approaches and technical terms. Little empirical research has addressed the conceptualization of goal conflict against the background of differing understandings from a structure-like and a process-like perspective. In the present article, we outline theoretical foundations of goal conflict from two perspectives: a structure- and a process-like perspective. Based on a comparative analysis and integration of these two perspectives, we systematically review empirical studies on goal conflict over 30 years of research. In doing so, we identify and discuss important conceptual dimensions of goal conflict, namely, goal conflict as a cognitive construct and an experiential instance, a focus on goal interrelations or on specific goal properties, and resource vs. inherent conflict, and the potential of these distinctions to further research on goal conflict. Finally, we present major challenges and pose questions that need to be addressed by future research.

    Historically, surgeons have had little formal training in conflict resolution; however, there has been an increasing body of evidence that poor conflict resolution skills may have an adverse impact on patient outcomes and career advancement. Furthermore, the Accreditation Council for Graduate Medical Education has recognized the importance of conflict resolution skills in resident training by mandating the training of communication skills and professionalism. These skills have often been taught in other professions, and surgeons may need to acquaint themselves with the literature from those fields. Conflict resolution techniques such as the 7-step model or principle-based conflict resolution can be applied to conflict in the operating room, wards, and among colleagues. We propose a model for conflict resolution by using the basic tools of the history and physical exam, a process well known to all physicians.

    2017-10-01

    This study aimed to test a proposed structural equation model in which bullying experience, conflict management styles and psychological empowerment predict psychological well-being among Chinese nursing students in clinical placement. Three hundred and sixty-six nursing students recruited from five hospitals in J city and Y city were assessed with self-report questionnaires on bullying experience, conflict management styles, psychological empowerment and psychological well-being including depression, self-esteem, and academic major satisfaction. Data were analyzed using SPSS version 20.0 and AMOS version 22.0. The evaluation parameters included the comparative fit index at .90, the goodness of fit index at .93, the root mean square error of approximation at .07, and χ²/df ratio at 2.66, indicating that the proposed structural equation model provided a good fit to the data. Experience of being bullied during clinical placement, conflict management styles and psychological empowerment explained 93.0% of the variance and had significant effects on psychological well-being, with conflict management styles and psychological empowerment mediating the association between bullying and psychological well-being. The findings indicated that mediation by conflict management styles and psychological empowerment alleviated the negative influence of bullying on psychological well-being. To limit bullying and its negative effects, development of effective guidelines to deal with bullying will be a critical tool for both Chinese nursing students and their instructors. Further research should incorporate conflict management styles and psychological empowerment into the specific intervention strategies for handling bullying behaviors among nursing students and staff nurses and promoting nursing students' psychological well-being. © 2017 Korean Society of Nursing Science

    2011-10-01

    Cells interact with their environment and they have to react adequately to internal and external changes such changes in nutrient composition, physical properties like temperature or osmolarity and other stresses. More specifically, they must be able to evaluate whether the external change is significant or just in the range of noise. Based on multiple external parameters they have to compute an optimal response. Cellular signaling pathways are considered as the major means of information perception and transmission in cells. Here, we review different attempts to quantify information processing on the level of individual cells. We refer to Shannon entropy, mutual information, and informal measures of signaling pathway cross-talk and specificity. Information theory in systems biology has been successfully applied to identification of optimal pathway structures, mutual information and entropy as system response in sensitivity analysis, and quantification of input and output information. While the study of information transmission within the framework of information theory in technical systems is an advanced field with high impact in engineering and telecommunication, its application to biological objects and processes is still restricted to specific fields such as neuroscience, structural and molecular biology. However, in systems biology dealing with a holistic understanding of biochemical systems and cellular signaling only recently a number of examples for the application of information theory have emerged.

    In the management of critical care units, leadership and conflict management are vital areas for the successful performance of the unit. In this article a practical approach to define competencies for leadership and principles and practices of conflict management are offered. This article is, by lack of relevant intensive care unit (ICU) literature, not evidence based, but it is the result of personal experience and a study of literature on leadership as well on conflicts and negotiations in non-medical areas. From this, information was selected that was recognisable to the authors and, thus, also seems to be useful knowledge for medical doctors in the ICU environment.

    It is now widely accepted that ethics is an essential part of educating health professionals. Despite a clear mandate to educators, there are differing approaches, in particular, how and where ethics is positioned in training programmes, underpinning philosophies and optimal modes of assessment. This paper explores varying practices and argues for a values based approach to ethics education. It then explores the possibility of using a web-based technology, the Values Exchange, to facilitate a values based approach. It uses the findings of a small scale study to signal the potential of the Values Exchange for engaging, meaningful and applied ethics education. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Full Text Available This article describes the methodology and the outcomes of an empirical study of conflict narratives. The narratological analysis deployed narratological catego­ries in the structuralist tradition based on Genette and was conducted with the help of the text annotation tool CATMA. The analysis aimed at covering as many narratological phenomena as possible by establishing 14 fields of narrato­logical phenomena that were annotated in a corpus of 39 factual narratives about situations at the workplace with and without conflicts. The evaluation of approximately 28,000 annotations brought to light a series of interrelations be­tween narratological phenomena and the presence or absence of conflicts in the narratives. Additionally, this approach led to the identification of some over­sights of narrative theory by detecting hitherto unnoticed interrelations among narratological concepts.

  12. Globalization and Conflict Management in Schools

    2009-12-01

    Full Text Available Globalization has brought many changes on the education systems and schools. These changes will be exemplified from thebasis of school finance, employee rights, curriculum, administration, and school-environment relations in this study. The studyalso reviews common types of conflicts experienced at schools as a result of globalization and the ways in which conflict couldbe managed. Following topics were discussed in the article: ‘Conflicts emerged from perspectives towards globalization,conflicts emerged from cross cultural differences, conflicts sourced from changes in the teaching and learning processes,conflicts sourced from the standardization efforts, conflicts sourced from the change in school-parents relations, conflictssourced from the process of finance related activities and conflicts sourced from information, communication andeducational technologies’. This article argues that schools cannot be isolated from the effects of globalization. Therefore sinceconflict is a normal occurrence in schools, school administrators should discover constructive approaches through carefuldiagnosis and an approach that transforms the conflicting situations into constructive experiences for the school and theeducation.

    The aim of the present study was to examine the longitudinal relationship between job performance-based self-esteem (JPB-SE) and work-home interaction (WHI) in terms of the direction of the interaction (work-to-home vs. home-to-work) and the effect (conflict vs. facilitation). A sample of 3,475 respondents from eight different occupational groups (lawyers, physicians, nurses, teachers, church ministers, bus drivers, and people working in advertising and information technology) supplied data at two points of time with a two-year time interval. The two-wave, cross-lagged structural equations modeling (SEM) analysis demonstrated reciprocal relationships between these variables, i.e., job performance-based self-esteem may act as a precursor as well as an outcome of work-home interaction. The strongest association was between job performance-based self-esteem and work-to-home conflict. Previous research on work-home interaction has mainly focused on situational factors. This longitudinal study expands the work-home literature by demonstrating how individual vulnerability (job performance-based self-esteem) contributes to the explanation of work-home interactions. © 2010 The Authors.

    2010-07-09

    In conflict tasks such as the Stroop, the Eriksen flanker or the Simon task, it is generally observed that the detection of conflict in the current trial reduces the impact of conflicting information in the subsequent trial; a phenomenon termed conflict adaptation. This higher-order cognitive control function has been assumed to be restricted to cases where conflict is experienced consciously. In the present experiment we manipulated the awareness of conflict-inducing stimuli in a metacontrast masking paradigm to directly test this assumption. Conflicting response tendencies were elicited either consciously (through primes that were weakly masked) or unconsciously (strongly masked primes). We demonstrate trial-by-trial conflict adaptation effects after conscious as well as unconscious conflict, which could not be explained by direct stimulus/response repetitions. These findings show that unconscious information can have a longer-lasting influence on our behavior than previously thought and further stretch the functional boundaries of unconscious cognition.

    2016-06-01

    Full Text Available Unmanned air vehicles have recently attracted attention of many researchers because of their potential civil applications. A systematic integration of unmanned air vehicles in non-segregated airspace is required that allows safe operation of unmanned air vehicles along with other manned aircrafts. One of the critical issues is conflict detection and resolution. This article proposes to solve unmanned air vehicles’ conflict detection and resolution problem in metropolis airspace. First, the structure of metropolis airspace in the coming future is studied, and the airspace conflict problem between different unmanned air vehicles is analyzed by velocity obstacle theory. Second, a conflict detection and resolution framework in metropolis is proposed, and factors that have influences on conflict-free solutions are discussed. Third, the multi-unmanned air vehicle conflict resolution problem is formalized as a nonlinear optimization problem with the aim of minimizing overall conflict resolution consumption. The safe separation constraint is further discussed to improve the computation efficiency. When the speeds of conflict-involved unmanned air vehicles are equal, the nonlinear safe separation constraint is transformed into linear constraints. The problem is solved by mixed integer convex programming. When unmanned air vehicles are with unequal speeds, we propose to solve the nonlinear optimization problem by stochastic parallel gradient descent–based method. Our approaches are demonstrated in computational examples.

  10. A Novel Evidence Theory and Fuzzy Preference Approach-Based Multi-Sensor Data Fusion Technique for Fault Diagnosis

    Directory of Open Access Journals (Sweden)

    Fuyuan Xiao

    2017-10-01

    Full Text Available The multi-sensor data fusion technique plays a significant role in fault diagnosis and in a variety of such applications, and the Dempster–Shafer evidence theory is employed to improve the system performance; whereas, it may generate a counter-intuitive result when the pieces of evidence highly conflict with each other. To handle this problem, a novel multi-sensor data fusion approach on the basis of the distance of evidence, belief entropy and fuzzy preference relation analysis is proposed. A function of evidence distance is first leveraged to measure the conflict degree among the pieces of evidence; thus, the support degree can be obtained to represent the reliability of the evidence. Next, the uncertainty of each piece of evidence is measured by means of the belief entropy. Based on the quantitative uncertainty measured above, the fuzzy preference relations are applied to represent the relative credibility preference of the evidence. Afterwards, the support degree of each piece of evidence is adjusted by taking advantage of the relative credibility preference of the evidence that can be utilized to generate an appropriate weight with respect to each piece of evidence. Finally, the modified weights of the evidence are adopted to adjust the bodies of the evidence in the advance of utilizing Dempster’s combination rule. A numerical example and a practical application in fault diagnosis are used as illustrations to demonstrate that the proposal is reasonable and efficient in the management of conflict and fault diagnosis.

    . Their developments, however, are largely due to experiment based trial and error approaches and while they do not require validation, they can be time consuming and resource intensive. Also, one may ask, can a truly new intensified unit operation be obtained in this way? An alternative two-stage approach is to apply...... a model-based synthesis method to systematically generate and evaluate alternatives in the first stage and an experiment-model based validation in the second stage. In this way, the search for alternatives is done very quickly, reliably and systematically over a wide range, while resources are preserved...... for focused validation of only the promising candidates in the second-stage. This approach, however, would be limited to intensification based on “known” unit operations, unless the PI process synthesis/design is considered at a lower level of aggregation, namely the phenomena level. That is, the model-based...

    Prior research has shown that surgeons who effectively manage operating room conflict engage in a problem-solving stage devoted to modifying systems that contribute to team conflict. The purpose of this study was to clarify how systems contributed to operating room team conflict and clarify what surgeons do to modify them. Focus groups of circulating nurses and surgeons were conducted at 5 academic medical centers. Narratives describing the contributions of systems to operating room conflict and behaviors used by surgeons to address those systems were analyzed using the constant comparative approach associated with a constructivist grounded theory approach. Operating room team conflict was affected by 4 systems-related factors: team features, procedural-specific staff training, equipment management systems, and the administrative leadership itself. Effective systems problem solving included advocating for change based on patient safety concerns. The results of this study provide clarity about how systems contribute to operating room conflict and what surgeons can do to effectively modify these systems. This information is foundational material for a conflict management educational program for surgeons. Copyright © 2013 Elsevier Inc. All rights reserved.

    2016-01-01

    Cognitive conflict resolution is critical to human survival in a rapidly changing environment. However, emotional conflict processing seems to be particularly important for human interactions. This study examined whether the time course of attentional modulation on emotional conflict processing was different from cognitive conflict processing during a flanker task. Results showed that emotional N200 and P300 effects, similar to colour conflict processing, appeared only during the relevant task. However, the emotional N200 effect preceded the colour N200 effect, indicating that emotional conflict can be identified earlier than cognitive conflict. Additionally, a significant emotional N100 effect revealed that emotional valence differences could be perceived during early processing based on rough aspects of input. The present data suggest that emotional conflict processing is modulated by top-down attention, similar to cognitive conflict processing (reflected by N200 and P300 effects). However, emotional conflict processing seems to have more time advantages during two different processing stages.

    Despite intensive study, the role of the dorsal medial frontal cortex (dMFC) in error monitoring and conflict processing remains actively debated. The current experiment manipulated conflict type (stimulus conflict only or stimulus and response selection conflict) and utilized a novel modeling approach to isolate error and conflict variance during a multimodal numeric Stroop task. Specifically, hemodynamic response functions resulting from two statistical models that either included or isolated variance arising from relatively few error trials were directly contrasted. Twenty-four participants completed the task while undergoing event-related functional magnetic resonance imaging on a 1.5-Tesla scanner. Response times monotonically increased based on the presence of pure stimulus or stimulus and response selection conflict. Functional results indicated that dMFC activity was present during trials requiring response selection and inhibition of competing motor responses, but absent during trials involving pure stimulus conflict. A comparison of the different statistical models suggested that relatively few error trials contributed to a disproportionate amount of variance (i.e., activity) throughout the dMFC, but particularly within the rostral anterior cingulate gyrus (rACC). Finally, functional connectivity analyses indicated that an empirically derived seed in the dorsal ACC/pre-SMA exhibited strong connectivity (i.e., positive correlation) with prefrontal and inferior parietal cortex but was anticorrelated with the default-mode network. An empirically derived seed from the rACC exhibited the opposite pattern, suggesting that sub-regions of the dMFC exhibit different connectivity patterns with other large scale networks implicated in internal mentations such as daydreaming (default-mode) versus the execution of top-down attentional control (fronto-parietal).

  19. The Evolution of Cooperation in Managed Groundwater Systems: An Agent-Based Modelling Approach

    Human interactions with groundwater systems often exhibit complex features that hinder the sustainable management of the resource. This leads to costly and persistent conflicts over groundwater at the catchment scale. One possible way to address these conflicts is by gaining a better understanding of how social and groundwater dynamics coevolve using agent-based models (ABM). Such models allow exploring 'bottom-up' solutions (i.e., self-organised governance systems), where the behaviour of individual agents (e.g., farmers) results in the emergence of mutual cooperation among groundwater users. There is significant empirical evidence indicating that this kind of 'bottom-up' approach may lead to more enduring and sustainable outcomes, compared to conventional 'top-down' strategies such as centralized control and water right schemes (Ostrom 1990). New modelling tools are needed to study these concepts systematically and efficiently. Our model uses a conceptual framework to study cooperation and the emergence of social norms as initially proposed by Axelrod (1986), which we adapted to groundwater management. We developed an ABM that integrates social mechanisms and the physics of subsurface flow. The model explicitly represents feedback between groundwater conditions and social dynamics, capturing the spatial structure of these interactions and the potential effects on cooperation levels in an agricultural setting. Using this model, we investigate a series of mechanisms that may trigger norms supporting cooperative strategies, which can be sustained and become stable over time. For example, farmers in a self-monitoring community can be more efficient at achieving the objective of sustainable groundwater use than government-imposed regulation. Our coupled model thus offers a platform for testing new schemes promoting cooperation and improved resource use, which can be used as a basis for policy design. Importantly, we hope to raise awareness of agent-based modelling as

The limitations of the study are considered and practical implications for the teaching of computer ethics are discussed.

  1. A new approach to hand-based authentication

    2007-04-01

    Hand-based authentication is a key biometric technology with a wide range of potential applications both in industry and government. Traditionally, hand-based authentication is performed by extracting information from the whole hand. To account for hand and finger motion, guidance pegs are employed to fix the position and orientation of the hand. In this paper, we consider a component-based approach to hand-based verification. Our objective is to investigate the discrimination power of different parts of the hand in order to develop a simpler, faster, and possibly more accurate and robust verification system. Specifically, we propose a new approach which decomposes the hand in different regions, corresponding to the fingers and the back of the palm, and performs verification using information from certain parts of the hand only. Our approach operates on 2D images acquired by placing the hand on a flat lighting table. Using a part-based representation of the hand allows the system to compensate for hand and finger motion without using any guidance pegs. To decompose the hand in different regions, we use a robust methodology based on morphological operators which does not require detecting any landmark points on the hand. To capture the geometry of the back of the palm and the fingers in suffcient detail, we employ high-order Zernike moments which are computed using an effcient methodology. The proposed approach has been evaluated on a database of 100 subjects with 10 images per subject, illustrating promising performance. Comparisons with related approaches using the whole hand for verification illustrate the superiority of the proposed approach. Moreover, qualitative comparisons with state-of-the-art approaches indicate that the proposed approach has comparable or better performance.

    Various research studies have suggested that among other variables that couples remain married if they successfully manage their interactions (marital communication based on acceptance of individual differences, problem solving skills, forgiveness, collaborative decision making, empathy and active listening) and constructively manage conflict. The study was aimed at examining the relation of conflict handling styles and marital conflicts among divorcing couples. As a descriptive -comparative study 60 couples out of 440 couples referred to the Crisis Intervention Center of the Isfahan Well-being Organization have selected. The tools implemented were Marital Conflicts (Barati & Sanaei, 1996) and Interpersonal Conflict Handling Styles Questionnaires (Thomas-Kilman, 1975). Their total reliabilities were, respectively, 0.74 and 0.87. Findings showed that there are no significant differences among their conflict handling styles and marital conflicts. Also, there was positive correlation between avoidance and competition styles and negative one between compromise, accommodation, and cooperation styles with marital conflicts. That is, these styles reduced couples' conflicts. Finally, wives had tendency to apply accommodation style and husbands tended to use accommodation and cooperation styles to handle their conflicts. It is suggested to be studied couples' views toward their own styles to handle marital conflicts and holding training courses to orient couples with advantages and disadvantages of marital conflict handling styles.

    The Chorus software is designed to investigate near-term, tactical conflict and loss of separation detection and resolution concepts for air traffic management. This software is currently being used in two different problem domains: en-route self- separation and sense and avoid for unmanned aircraft systems. This paper describes the core resolution algorithms that are part of Chorus. The combination of several features of the Chorus program distinguish this software from other approaches to conflict and loss of separation resolution. First, the program stores a history of state information over time which enables it to handle communication dropouts and take advantage of previous input data. Second, the underlying conflict algorithms find resolutions that solve the most urgent conflict, but also seek to prevent secondary conflicts with the other aircraft. Third, if the program is run on multiple aircraft, and the two aircraft maneuver at the same time, the result will be implicitly co-ordinated. This implicit coordination property is established by ensuring that a resolution produced by Chorus will comply with a mathematically-defined criteria whose correctness has been formally verified. Fourth, the program produces both instantaneous solutions and kinematic solutions, which are based on simple accel- eration models. Finally, the program provides resolutions for recovery from loss of separation. Different versions of this software are implemented as Java and C++ software programs, respectively.

  5. Technology-supported environments for learning through cognitive conflict

    Full Text Available This paper examines ways in which the idea of cognitive conflict is used to facilitate learning, looking at the design and use of learning environments for this purpose. Drawing on previous work in science education and educational computing, three approaches to the design of learning environments utilizing cognitive conflict are introduced. These approaches are described as confrontational, guiding and explanatory, based on the level of the designer's concern with learners' pre-existing understanding, the extent of modification to the learner's conceptual structures intended by the designer, and the directness of steering the learner to the desired understanding. The examples used to illustrate the three approaches are taken from science education, specifically software for learning about Newtonian physics; it is contended however that the argument of the paper applies more broadly, to learning environments for many curriculum areas for school levels and in higher education.

    Children in northern Uganda have undergone significant psychosocial stress during the region's lengthy conflict. A Psychosocial Structured Activities (PSSA) program was implemented in 21 schools identified as amongst those most severely affected by conflict-induced displacement across Gulu and Amuru Districts. The PSSA intervention comprised a series of 15 class sessions designed to progressively increase children's resilience through structured activities involving drama, movement, music and art (with additional components addressing parental support and community involvement). Eight schools were selected by random quota sampling from those schools receiving the PSSA intervention. Two hundred and three children were identified in these schools as being scheduled to receive intervention, and were followed up 12 months later following engagement with PSSA activities. A comparison group comprised 200 children selected from schools that had met inclusion criteria for receipt of intervention, but were not scheduled for intervention coverage until later. Preliminary research used participatory focus group methodology to determine local indicators of child well-being as viewed by parents, teachers, and children respectively. Pre- and post- assessments focused on ratings for each child - by parents, teachers and children - with respect to these indicators. Significant increases in ratings of child well-being were observed in both intervention and comparison groups over a 12-month period. However, the well-being of children who had received the PSSA intervention increased significantly more than for children in the comparison group, as judged by child and parent (but not teacher) report. This effect was evident despite considerable loss-to-follow-up at post-testing as a result of return of many households to communities of origin. General improvement in child well-being over a 12-month period suggests that recovery and reconstruction efforts in Northern Uganda following

    Specialty trainees in genitourinary medicine (GUM) are required to attain competencies described in the GUM higher specialty training curriculum by the end of their training, but learning opportunities available may conflict with service delivery needs. In response to poor feedback on trainee satisfaction surveys, a four-year modular training programme was developed to achieve a curriculum competencies-based approach to training. We evaluated the clinical opportunities of the new programme to determine: (1) Whether opportunity cost of training to service delivery is justifiable; (2) Which competencies are inadequately addressed by direct clinical opportunities alone and (3) Trainee satisfaction. Local faculty and trainees assessed the 'usefulness' of the new modular programme to meet each curriculum competence. The annual General Medical Council (GMC) national training survey assessed trainee satisfaction. The clinical opportunities provided by the modular training programme were sufficiently useful for attaining many competencies. Trainee satisfaction as captured by the GMC survey improved from two reds pre- to nine greens post-intervention on a background of rising clinical activity in the department. The curriculum competencies-based approach to training offers an objective way to balance training with service provision and led to an improvement in GMC survey satisfaction.

  11. Knowledge-based biomedical word sense disambiguation: comparison of approaches

    Full Text Available Abstract Background Word sense disambiguation (WSD algorithms attempt to select the proper sense of ambiguous terms in text. Resources like the UMLS provide a reference thesaurus to be used to annotate the biomedical literature. Statistical learning approaches have produced good results, but the size of the UMLS makes the production of training data infeasible to cover all the domain. Methods We present research on existing WSD approaches based on knowledge bases, which complement the studies performed on statistical learning. We compare four approaches which rely on the UMLS Metathesaurus as the source of knowledge. The first approach compares the overlap of the context of the ambiguous word to the candidate senses based on a representation built out of the definitions, synonyms and related terms. The second approach collects training data for each of the candidate senses to perform WSD based on queries built using monosemous synonyms and related terms. These queries are used to retrieve MEDLINE citations. Then, a machine learning approach is trained on this corpus. The third approach is a graph-based method which exploits the structure of the Metathesaurus network of relations to perform unsupervised WSD. This approach ranks nodes in the graph according to their relative structural importance. The last approach uses the semantic types assigned to the concepts in the Metathesaurus to perform WSD. The context of the ambiguous word and semantic types of the candidate concepts are mapped to Journal Descriptors. These mappings are compared to decide among the candidate concepts. Results are provided estimating accuracy of the different methods on the WSD test collection available from the NLM. Conclusions We have found that the last approach achieves better results compared to the other methods. The graph-based approach, using the structure of the Metathesaurus network to estimate the relevance of the Metathesaurus concepts, does not perform well
