We observe that these approaches have complementary strengths and weaknesses. In this dissertation, we propose the integration of actor programming models in database systems....... In doing so, we lay down a vision for a new class of systems called actor database systems. To explore this vision, this dissertation crystallizes the notion of an actor database system by defining its feature set in light of current application and hardware trends. In order to explore the viability...... of the outlined vision, a new programming model named Reactors has been designed to enrich classic relational database programming models with logical actor programming constructs. To support the reactor programming model, a high-performance in-memory multi-core OLTP database system named REACTDB has been built...

    Generating virtual actors is one of the most challenging fields in computer graphics. The reconstruction of a realistic virtual actor has been paid attention by the academic research and the film industry to generate human-like virtual actors. Many movies were acted by human-like virtual actors, where the audience cannot distinguish between real and virtual actors. The synthesis of realistic virtual actors is considered a complex process. Many techniques are used to generate a realistic virtual actor; however they usually require expensive hardware equipment. In this paper, a low-cost system that generates near-realistic virtual actors is presented. The facial features of the real actor are blended with a virtual head that is attached to the actor's body. Comparing with other techniques that generate virtual actors, the proposed system is considered a low-cost system that requires only one camera that records the scene without using any expensive hardware equipment. The results of our system show that the system generates good near-realistic virtual actors that can be used on many applications.

  6. Evolving Norms at the Intersection of Health and Trade

    2014-01-01

    There has been growing tension at the intersection of health and economic policymaking as global governance has increased across sectors. This tension has been particularly evident between tobacco control and trade policy, as the international norms that frame them – particularly the Framework Convention on Tobacco Control and the World Trade Organization (WTO) – have continued to institutionalize. Using five case studies of major tobacco-related trade disputes from the principal multilateral system of trade governance – the WTO/General Agreement on Tariffs and Trade – we trace the evolution of these interacting norms over nearly 25 years. Our analytic framework particularly focuses on the actors that advance, defend and challenge these norms. We find that an increasingly broad network, which includes governments, intergovernmental organizations, non-governmental organizations and members of the epistemic community, is playing a more active role in seeking to resolve these tensions. Moreover, key economic actors are beginning to incorporate health more actively in their messaging and activities. We also demonstrate that the most recent resonant messages reflect a more nuanced integration of the two norms. The tobacco control example has direct relevance to related policy areas, including environment, safety, access to medicines, diet, and alcohol. PMID:24603086

  7. Cyber Norms for Civilian Nuclear Power Plants

    2016-11-01

    The international community agrees that the safe operation of civilian nuclear infrastructure is in every population’s best interest. One challenge each government must address is defining and agreeing to a set of acceptable norms of behavior in cyberspace as they relate to these facilities. The introduction of digital systems and networking technologies into these environments has led to the possibility that control and supporting computer systems are now accessible and exploitable, especially where interconnections to global information and communications technology (ICT) networks exist. The need for norms of behavior in cyberspace includes what is expected of system architects and cyber defenders as well as adversaries who should abide by rules of engagement even while conducting acts that violate national and international laws. The goal of this paper is to offer three behavioral cyber norms to improve the overall security of the ICT and Operational Technology (OT) networks and systems that underlie the operations of nuclear facilities. These norms of behavior will be specifically defined with the goals of reducing the threats associated to the theft of nuclear materials, accidental release of radiation and sabotage of nuclear processes. These norms would also include instances where an unwitting attacker or intelligence collection entity inadvertently makes their way into a nuclear facility network or system and can recognize they are in a protected zone and an approach to ensuring that these zones are not exploitable by bad actors to place their sensitive cyber effect delivery systems.

  8. Privacy, technology, and norms: the case of Smart Meters.

    2015-05-01

    Norms shift and emerge in response to technological innovation. One such innovation is Smart Meters - components of Smart Grid energy systems capable of minute-to-minute transmission of consumer electricity use information. We integrate theory from sociological research on social norms and privacy to examine how privacy threats affect the demand for and expectations of norms that emerge in response to new technologies, using Smart Meters as a test case. Results from three vignette experiments suggest that increased threats to privacy created by Smart Meters are likely to provoke strong demand for and expectations of norms opposing the technology and that the strength of these normative rules is at least partly conditional on the context. Privacy concerns vary little with actors' demographic characteristics. These findings contribute to theoretical understanding of norm emergence and have practical implications for implementing privacy protections that effectively address concerns of electricity users.

    2014-01-01

    Norms and normative multiagent systems have become the subjects of interest for many researchers. Such interest is caused by the need for agents to exploit the norms in enhancing their performance in a community. The term norm is used to characterize the behaviours of community members. The concept of normative multiagent systems is used to facilitate collaboration and coordination among social groups of agents. Many researches have been conducted on norms that investigate the fundamental concepts, definitions, classification, and types of norms and normative multiagent systems including normative architectures and normative processes. However, very few researches have been found to comprehensively study and analyze the literature in advancing the current state of norms and normative multiagent systems. Consequently, this paper attempts to present the current state of research on norms and normative multiagent systems and propose a norm's life cycle model based on the review of the literature. Subsequently, this paper highlights the significant areas for future work. PMID:25110739

  16. Nudging Armed Groups: How Civilians Transmit Norms of Protection

    Directory of Open Access Journals (Sweden)

    Oliver Kaplan

    2013-12-01

    Full Text Available What are the varying roles that norms play to either enable or constrain violence in armed conflict settings? The article examines this question by drawing on experiences from communities and armed groups in Colombia and Syria. It begins by presenting an explanation of how norms of violence and nonviolence may arise within communities and influence the behavior of civilian residents, reducing the chances of them becoming involved with armed groups. It then considers how civilian communities can transmit those same norms, shared understandings, and patterns of interaction to the ranks of illegal armed groups and subsequently shape their decisions about the use of violence against civilians. The author argues that civilians may be better positioned to promote the principles codified in International Humanitarian Law than international humanitarian organizations because they have closer contact with irregular armed actors and are viewed with greater legitimacy. The analysis illustrates that to better understand civilian protection mechanisms it is essential to study the interactions between communities and armed actors.

  18. earGram Actors: An Interactive Audiovisual System Based on Social Behavior

    Directory of Open Access Journals (Sweden)

    Peter Beyls

    2015-11-01

    Full Text Available In multi-agent systems, local interactions among system components following relatively simple rules often result in complex overall systemic behavior. Complex behavioral and morphological patterns have been used to generate and organize audiovisual systems with artistic purposes. In this work, we propose to use the Actor model of social interactions to drive a concatenative synthesis engine called earGram in real time. The Actor model was originally developed to explore the emergence of complex visual patterns. On the other hand, earGram was originally developed to facilitate the creative exploration of concatenative sound synthesis. The integrated audiovisual system allows a human performer to interact with the system dynamics while receiving visual and auditory feedback. The interaction happens indirectly by disturbing the rules governing the social relationships amongst the actors, which results in a wide range of dynamic spatiotemporal patterns. A performer thus improvises within the behavioural scope of the system while evaluating the apparent connections between parameter values and actual complexity of the system output.

  19. Institutional and Actor-Oriented Factors Constraining Expert-Based Forest Information Exchange in Europe: A Policy Analysis from an Actor-Centred Institutionalist Approach

    Directory of Open Access Journals (Sweden)

    Tanya Baycheva-Merger

    2018-03-01

    Full Text Available Adequate and accessible expert-based forest information has become increasingly in demand for effective decisions and informed policies in the forest and forest-related sectors in Europe. Such accessibility requires a collaborative environment and constant information exchange between various actors at different levels and across sectors. However, information exchange in complex policy environments is challenging, and is often constrained by various institutional, actor-oriented, and technical factors. In forest policy research, no study has yet attempted to simultaneously account for these multiple factors influencing expert-based forest information exchange. By employing a policy analysis from an actor-centred institutionalist perspective, this paper aims to provide an overview of the most salient institutional and actor-oriented factors that are perceived as constraining forest information exchange at the national level across European countries. We employ an exploratory research approach, and utilise both qualitative and quantitative methods to analyse our data. The data was collected through a semi-structured survey targeted at forest and forest-related composite actors in 21 European countries. The results revealed that expert-based forest information exchange is constrained by a number of compound and closely interlinked institutional and actor-oriented factors, reflecting the complex interplay of institutions and actors at the national level. The most salient institutional factors that stand out include restrictive or ambiguous data protection policies, inter-organisational information arrangements, different organisational cultures, and a lack of incentives. Forest information exchange becomes even more complex when actors are confronted with actor-oriented factors such as issues of distrust, diverging preferences and perceptions, intellectual property rights, and technical capabilities. We conclude that expert-based forest information

  1. Subband Adaptive Filtering with l1-Norm Constraint for Sparse System Identification

    Directory of Open Access Journals (Sweden)

    Young-Seok Choi

    2013-01-01

    Full Text Available This paper presents a new approach of the normalized subband adaptive filter (NSAF which directly exploits the sparsity condition of an underlying system for sparse system identification. The proposed NSAF integrates a weighted l1-norm constraint into the cost function of the NSAF algorithm. To get the optimum solution of the weighted l1-norm regularized cost function, a subgradient calculus is employed, resulting in a stochastic gradient based update recursion of the weighted l1-norm regularized NSAF. The choice of distinct weighted l1-norm regularization leads to two versions of the l1-norm regularized NSAF. Numerical results clearly indicate the superior convergence of the l1-norm regularized NSAFs over the classical NSAF especially when identifying a sparse system.

    2015-10-01

    Full Text Available Economic actors are the main trade player in the World Trade Organization, although, the relation between WTO and economic actor is built by trade regulation that is negotiated among the WTO Members. Nothing in the WTO regulates economic actors to involve directly in the WTO, especially in the WTO dispute settlement system. Nevertheless, the debate amongst experts regarding the involvement of economic actors in the WTO dispute settlement system is unavoidable. This article therefore discusses the possibility of the involvement of economic actors in the WTO dispute settlement system, whether there is legal and political point of views

    2017-01-01

    We present an extension of the actor model with real-time, including deadlines associated with messages, and explicit application-level scheduling policies, e.g.,"earliest deadline first" which can be associated with individual actors. Schedulability analysis in this setting amounts to checking whether, given a scheduling policy for each actor, every task is processed within its designated deadline. To check schedulability, we introduce a compositional automata-theoretic approach, based on maximal use of model checking combined with testing. Behavioral interfaces define what an actor expects from the environment, and the deadlines for messages given these assumptions. We use model checking to verify that actors match their behavioral interfaces. We extend timed automata refinement with the notion of deadlines and use it to define compatibility of actor environments with the behavioral interfaces. Model checking of compatibility is computationally hard, so we propose a special testing process. We show that the analyses are decidable and automate the process using the Uppaal model checker.

  5. From Norm Adoption to Norm Internalization

    Science.gov (United States)

    Conte, Rosaria; Andrighetto, Giulia; Villatoro, Daniel

    In this presentation, advances in modeling the mental dynamics of norms will be presented. In particular, the process from norm-adoption, possibly yielding new normative goals, to different forms of norm compliance will be focused upon, including norm internalization, which is at study in social-behavioral sciences and moral philosophy since long. Of late, the debate was revamped within the rationality approach pointing to the role of norm internalization as a less costly and more reliable enforcement system than social control. So far, poor attention was paid to the mental underpinnings of internalization. In this presentation, a rich cognitive model of different types, degrees and factors of internalization is shown. The initial implementation of this model on EMIL-A, a normative agent architecture developed and applied to the.

    2014-12-01

    Social norms such as social rules and conventions play a pivotal role in sustaining system order by regulating and controlling individual behaviors toward a global consensus in large-scale distributed systems. Systematic studies of efficient mechanisms that can facilitate the emergence of social norms enable us to build and design robust distributed systems, such as electronic institutions and norm-governed sensor networks. This paper studies the emergence of social norms via learning from repeated local interactions in networked multiagent systems. A collective learning framework, which imitates the opinion aggregation process in human decision making, is proposed to study the impact of agent local collective behaviors on the emergence of social norms in a number of different situations. In the framework, each agent interacts repeatedly with all of its neighbors. At each step, an agent first takes a best-response action toward each of its neighbors and then combines all of these actions into a final action using ensemble learning methods. Extensive experiments are carried out to evaluate the framework with respect to different network topologies, learning strategies, numbers of actions, influences of nonlearning agents, and so on. Experimental results reveal some significant insights into the manipulation and control of norm emergence in networked multiagent systems achieved through local collective behaviors.

    Cultural considerations in social anxiety are a rarely investigated topic although it seems likely that differences between countries in social norms may relate to the extent of social anxiety. The present study investigated individuals' personal and perceived cultural norms and their relation to social anxiety and fear of blushing. A total of 909 participants from eight countries completed vignettes describing social situations and evaluated the social acceptability of the behavior of the main actor both from their own, personal perspective as well as from a cultural viewpoint. Personal and cultural norms showed somewhat different patterns in comparison between types of countries (individualistic/collectivistic). According to reported cultural norms, collectivistic countries were more accepting toward socially reticent and withdrawn behaviors than was the case in individualistic countries. In contrast, there was no difference between individualistic and collectivistic countries on individuals' personal perspectives regarding socially withdrawn behavior. Collectivistic countries also reported greater levels of social anxiety and more fear of blushing than individualistic countries. Significant positive relations occurred between the extent to which attention-avoiding behaviors are accepted in a culture and the level of social anxiety or fear of blushing symptoms. These results provide initial evidence that social anxiety may be related to different cultural norms across countries.

    The current study examined the relations between observed normativity and deviance during adolescents' and young adults' conversations about sex with their friends and their individual perceptions of sexual peer norms. Participants were 16-21-year-old same-sex friendship dyads (31 male and 30 female dyads) who performed a peer interaction task that consisted of five discussion assignments focusing on party planning, sexual double standards, condom use, homosexuality, and consensual sex. Videotaped discussions were coded to capture the amounts of normative talk (e.g., consistent with notions of healthy sexuality) and deviant talk (e.g., consistent with notions of risky sexuality), and the verbal or nonverbal reinforcement thereof. Participants also completed individual questionnaires to assess their perceived sexual descriptive norms, injunctive norms, pressure, and risk norms among their peers. Actor-partner interdependence model (APIM) results revealed that youths' perceived descriptive, injunctive, and risk norms, but not their experienced peer pressure, were related to both their own (actor effects) and their friends' (partner effects) normativity and deviance. Overall, more deviance was related to perceiving friends to be more sexually active, more approving of having sex, and engaging in more risky sex, whereas more normativity was related to these perceptions in the opposite direction. Gender differences in the APIMs indicated that interactive normativity and deviance was related to perceived descriptive, injunctive, and risk norms for boys, but only to perceived injunctive norms for girls. These findings demonstrate the importance of assessing the dyadic nature of youths' sexual communication with friends, their relation to individual sexual peer norm perceptions, and gender differences therein.

  10. International Political Actorness of the European Union: Evaluation Criteria

    Directory of Open Access Journals (Sweden)

    GNATYUK N.N.

    2014-06-01

    Full Text Available The European Union is a completely new international entity which is hard to evaluate using traditional criteria of political actorness. Its active international presence stimulates the modeling of international actor features beyond the scope of “state-international organization” scheme. The concept of international actorness serves as a starting point for the development of appropriate analytical model. Unlike the traditional state-centered approaches which define an international actor through its affiliation witch the international system, this concept operates at the internal level of international entity and at the international structure level. Furthermore, both of these levels are treated as ontologically neutral and mutually constitutive. This basic theoretical scheme is used for elaboration of evaluation criteria of political actorness. The proposed system of criteria is based on drawing, synthesizing and developing the main writings on “new international actors” since the times of classic work by Carol A. Cosgrove and Kenneth J. Twitchett. The key elements of actorness assessed in this article include defining of capacity to act on the global scene as well as the acceptance by other actors and by international system as a whole. At the internal level, the EU’s actor capacity is measured by assessing its core elements ranging from core aspects, such as autonomy, authority, actor capability, coherence and cohesion to identity aspects. On the external level, the decisive criteria are recognition and acceptance by others which reflect expectations and perceptions of the EU. The proposed approach of evaluating the international actorness enables us to consider the political activity of the EU on the basis of coordinated system of interaction between the variables of international and domestic levels of the analysis. Furthermore, this contributes to the development of cumulative, coherent, and comprehensive theory of international

    2007-10-01

    Full Text Available ERP systems are now an important component of information technology architecture in most large and medium sized companies. As such, it is inevitable that the activities undertaken to align this component to business requirements, conduct its evolution and ensure its performance and availability become increasingly important to companies’ IT areas. Success of these activities relies upon knowledge and participation of various actors inside and outside the IT area, imposing challenges not observed in internally developed systems. This paper proposes a model for the analysis of ERP systems management based on a previous work on the subject with the inclusion of the IT capabilities model and a description of the actors (stakeholders involved in the process of using an ERP system in a company. The proposed model is the basis for an exploratory survey conducted with 85 Brazilian companies whose results also comprise this text. The results suggest that only part of the capabilities is present and only part of the actors effectively participates on the ERP systems management effort.

    Replacing the triangle inequality, in the definition of a norm, by $|x + y| ^{q}\\leq 2^{q-1}(|x| ^{q} + |y| ^{q}) $, we introduce the notion of a q-norm. We establish that every q-norm is a norm in the usual sense, and that the converse is true as well.

    2018-01-01

    In recent years, subspace System Identification (SI) algorithms have seen increased research, stemming from advanced minimization methods being applied to the Nuclear Norm (NN) approach in system identification. These minimization algorithms are based on hard computing methodologies. To the authors’ knowledge, as of now, there has been no work reported that utilizes soft computing algorithms to address the minimization problem within the nuclear norm SI framework. A linear, time-invariant, discrete time system is used in this work as the basic model for characterizing a dynamical system to be identified. The main objective is to extract a mathematical model from collected experimental input-output data. Hankel matrices are constructed from experimental data, and the extended observability matrix is employed to define an estimated output of the system. This estimated output and the actual - measured - output are utilized to construct a minimization problem. An embedded rank measure assures minimum state realization outcomes. Current NN-SI algorithms employ hard computing algorithms for minimization. In this work, we propose a simple Tabu Search (TS) algorithm for minimization. TS algorithm based SI is compared with the iterative Alternating Direction Method of Multipliers (ADMM) line search optimization based NN-SI. For comparison, several different benchmark system identification problems are solved by both approaches. Results show improved performance of the proposed SI-TS algorithm compared to the NN-SI ADMM algorithm.

    An important area in the discourse on gender and water is water supply where women are seen as the key actors and beneficiaries. A human rights approach to development has been adopted with access to safe water explicitly recognized as a basic human right. This right places a legal obligation upon governments to translate the international norms into practice. But does explicitly acknowledging the human right to water make a practical difference in women's lives? Using an actor-oriented persp...

  16. Digital Social Norm Enforcement: Online Firestorms in Social Media.

    Actors of public interest today have to fear the adverse impact that stems from social media platforms. Any controversial behavior may promptly trigger temporal, but potentially devastating storms of emotional and aggressive outrage, so called online firestorms. Popular targets of online firestorms are companies, politicians, celebrities, media, academics and many more. This article introduces social norm theory to understand online aggression in a social-political online setting, challenging the popular assumption that online anonymity is one of the principle factors that promotes aggression. We underpin this social norm view by analyzing a major social media platform concerned with public affairs over a period of three years entailing 532,197 comments on 1,612 online petitions. Results show that in the context of online firestorms, non-anonymous individuals are more aggressive compared to anonymous individuals. This effect is reinforced if selective incentives are present and if aggressors are intrinsically motivated.

  17. ACTOR`S EXPRESSIVENESS: PHYSICAL ACTION AS A LANGUAGE OF ARCHETYPES

    2016-06-01

    Full Text Available Physical activity is the main element of the nonverbal expressiveness of the actor. Th e nonpsychological theatre of Europe in the second half of the 20th century was looking for the actor`s possibility of physical action for revealing the archetypal image of the character. Expressing the meanings similar among themselves in diff erent Nations, they connect the actors and spectators at the level of feelings, of the subconscious. Destroying the barriers in people’s minds which divides them into Europeans and Asians, or French and Germans, they are understandable to any audience regardless of their cultural or linguistic affiliation.

    Awareness is a concept familiar to specialists within the field of Computer Supported Cooperative Work (CSCW). It is superior for analysing and describing some of the ad hoc work activities that unfold in cooperation. Such informal activities are outside the scope of engineers’ formal models, whi...... that shape computer systems. The aim, thus, is to portray cooperative work in a way that can be valuable for engineers implementing marine technology. We do so by way of presenting a transferring technique (2T) using insights from the CSCW field and Actor Network Theory (ANT)....

    2016-12-01

    To explore how actors connect in a system aiming at promoting the establishment of a midwifery profession in Nepal. A qualitative explorative study based on the framework of Complex Adaptive Systems. Semi-structured interviews were conducted with 17 key people representing eight different organisations (actors) promoting the development of the midwifery profession. The actors' connections can be described with a complex set of facilitators for and barriers to promoting the establishment of a midwifery profession. The identified facilitators for this establishment in Nepal are (1) a common goal and (2) a desire to collaborate, whilst the barriers are (1) different political interests and priorities, (2) competing interests of the nursing profession and societal views, (3) divergent academic opinions on a midwifery profession, and (4) insufficient communication. The results also showed that Nepalese society cannot distinguish between nursing and midwifery and that the public support for a midwifery profession was hence minimal. The move of midwifery from an occupation to a profession in Nepal is an on-going, challenging process. The study indicates the importance of understanding the motivations of, and barriers perceived by, actors that can promote or obstruct the establishment of the midwifery profession. It also points to the importance of informing the wider public about the role and responsibility of an autonomous midwifery profession. Copyright © 2016 Elsevier B.V. All rights reserved.

  1. Efficient Actor Recovery Paradigm for Wireless Sensor and Actor Networks.

    Science.gov (United States)

    Mahjoub, Reem K; Elleithy, Khaled

    2017-04-14

    The actor nodes are the spine of wireless sensor and actor networks (WSANs) that collaborate to perform a specific task in an unverified and uneven environment. Thus, there is a possibility of high failure rate in such unfriendly scenarios due to several factors such as power consumption of devices, electronic circuit failure, software errors in nodes or physical impairment of the actor nodes and inter-actor connectivity problem. Therefore, it is extremely important to discover the failure of a cut-vertex actor and network-disjoint in order to improve the Quality-of-Service (QoS). In this paper, we propose an Efficient Actor Recovery (EAR) paradigm to guarantee the contention-free traffic-forwarding capacity. The EAR paradigm consists of a Node Monitoring and Critical Node Detection (NMCND) algorithm that monitors the activities of the nodes to determine the critical node. In addition, it replaces the critical node with backup node prior to complete node-failure which helps balancing the network performance. The packets are handled using Network Integration and Message Forwarding (NIMF) algorithm that determines the source of forwarding the packets; either from actor or sensor. This decision-making capability of the algorithm controls the packet forwarding rate to maintain the network for a longer time. Furthermore, for handling the proper routing strategy, Priority-Based Routing for Node Failure Avoidance (PRNFA) algorithm is deployed to decide the priority of the packets to be forwarded based on the significance of information available in the packet. To validate the effectiveness of the proposed EAR paradigm, the proposed algorithms were tested using OMNET++ simulation.

  2. Norm estimates of complex symmetric operators applied to quantum systems

    Prodan, Emil; Garcia, Stephan R; Putinar, Mihai

    2006-01-01

    This paper communicates recent results in the theory of complex symmetric operators and shows, through two non-trivial examples, their potential usefulness in the study of Schroedinger operators. In particular, we propose a formula for computing the norm of a compact complex symmetric operator. This observation is applied to two concrete problems related to quantum mechanical systems. First, we give sharp estimates on the exponential decay of the resolvent and the single-particle density matrix for Schroedinger operators with spectral gaps. Second, we provide new ways of evaluating the resolvent norm for Schroedinger operators appearing in the complex scaling theory of resonances

  3. Local energy governance in vermont: an analysis of energy system transition strategies and actor capacity

    Science.gov (United States)

    Rowse, Tarah

    While global, national, and regional efforts to address climate and energy challenges remain essential, local governments and community groups are playing an increasingly stronger and vital role. As an active state in energy system policy, planning and innovation, Vermont offers a testing ground for research into energy governance at the local level. A baseline understanding of the energy planning and energy organizing activities initiated at the local level can support efforts to foster a transition to a sustainable energy system in Vermont. Following an inductive, applied and participatory approach, and grounded in the fields of sustainability transitions, energy planning, and community energy, this research project identifies conditions for change, including opportunities and challenges, within Vermont energy system decision-making and governance at the local level. The following questions are posed: What are the main opportunities and challenges for sustainable energy development at the town level? How are towns approaching energy planning? What are the triggers that will facilitate a faster transition to alternative energy systems, energy efficiency initiatives, and localized approaches? In an effort to answer these questions two studies were conducted: 1) an analysis of municipal energy plans, and 2) a survey of local energy actors. Study 1 examined Vermont energy planning at the state and local level through a review and comparison of 40 municipal plan energy chapters with the state 2011 Comprehensive Energy Plan. On average, municipal plans mentioned just over half of the 24 high-level strategies identified in the Comprehensive Energy Plan. Areas of strong and weak agreement were examined. Increased state and regional interaction with municipal energy planners would support more holistic and coordinated energy planning. The study concludes that while municipalities are keenly aware of the importance of education and partnerships, stronger policy mechanisms

    Science.gov (United States)

    Kiumarsi, Bahare; Lewis, Frank L

    2015-01-01

    This paper presents a partially model-free adaptive optimal control solution to the deterministic nonlinear discrete-time (DT) tracking control problem in the presence of input constraints. The tracking error dynamics and reference trajectory dynamics are first combined to form an augmented system. Then, a new discounted performance function based on the augmented system is presented for the optimal nonlinear tracking problem. In contrast to the standard solution, which finds the feedforward and feedback terms of the control input separately, the minimization of the proposed discounted performance function gives both feedback and feedforward parts of the control input simultaneously. This enables us to encode the input constraints into the optimization problem using a nonquadratic performance function. The DT tracking Bellman equation and tracking Hamilton-Jacobi-Bellman (HJB) are derived. An actor-critic-based reinforcement learning algorithm is used to learn the solution to the tracking HJB equation online without requiring knowledge of the system drift dynamics. That is, two neural networks (NNs), namely, actor NN and critic NN, are tuned online and simultaneously to generate the optimal bounded control policy. A simulation example is given to show the effectiveness of the proposed method.

    2018-03-01

    The Actor model of concurrent computation discretizes a problem into a series of independent units or actors that interact only through the exchange of messages. Without direct coupling between individual components, an Actor-based system is inherently concurrent and fault-tolerant. These traits lend themselves to so-called "Big Data" applications in which the volume of data to analyze requires a distributed multi-system design. For a practical demonstration of the Actor computational model, a system was developed to assist with the automated analysis of Nondestructive Evaluation (NDE) datasets using the open source Myriad Data Reduction Framework. A machine learning model trained to detect damage in two-dimensional slices of C-Scan data was deployed in a streaming data processing pipeline. To demonstrate the flexibility of the Actor model, the pipeline was deployed on a local system and re-deployed as a distributed system without recompiling, reconfiguring, or restarting the running application.

  8. Intermediaries as Innovating Actors in the Transition to a Sustainable Energy System

    Directory of Open Access Journals (Sweden)

    Julia Backhaus

    2010-07-01

    Full Text Available In transitions of large sociotechnical systems, intermediary organisations can emerge as mediators in between several actor groups and facilitate communication and collaboration towards common goals. They can support the establishment of new actor networks and the articulation and alignment of interests to bring about desired changes. In this article, current efforts towards a more sustainable energy system serve as an exemplary context of intermediary work. The field under scrutiny, demand side management, aims to decrease energy consumption. Unfortunately, the role and work of intermediaries as implementers of demand side management projects often remains underappreciated.
    Research into the reasons of successes and failures of intermediary work and a theoretical corroboration for their practical work can help intermediaries to improve their programme designs and implementation strategies. The EC FP7-funded Changing Behaviour project aims to support intermediaries with strategic activities to improve demand side management programmes and bring about lasting behavioural changes. Paying more attention to context, stakeholders, monitoring, evaluation and learning enables the development of tailor-made, widely supported projects with higher chances of success.
    In addition to practical support for their work, intermediaries can benefit from stronger policy support. Understanding and appreciation of their work as contribution to policy implementation, e.g. towards energy saving targets, could motivate such support. A stable policy and financial environment with long-term implementation plans and funding schemes provides a fertile ground for intermediary activities. Active participation of policy actors in demand side management programmes can create networks sustaining longer-lasting change.

  9. Self-Recovering Sensor-Actor Networks

    Full Text Available Wireless sensor-actor networks are a recent development of wireless networks where both ordinary sensor nodes and more sophisticated and powerful nodes, called actors, are present. In this paper we formalize a recently introduced algorithm that recovers failed actor communication links via the existing sensor infrastructure. We prove via refinement that the recovery is terminating in a finite number of steps and is distributed, thus self-performed by the actors. Most importantly, we prove that the recovery can be done at different levels, via different types of links, such as direct actor links or indirect links between the actors, in the latter case reusing the wireless infrastructure of sensors. This leads to identifying coordination classes, e.g., for delegating the most security sensitive coordination to the direct actor-actor coordination links, the least real-time constrained coordination to indirect links, and the safety critical coordination to both direct actor links and indirect sensor paths between actors. Our formalization is done using the theorem prover in the RODIN platform.

  10. Moral actor, selfish agent.

    People are motivated to behave selfishly while appearing moral. This tension gives rise to 2 divergently motivated selves. The actor-the watched self-tends to be moral; the agent-the self as executor-tends to be selfish. Three studies present direct evidence of the actor's and agent's distinct motives. To recruit the self-as-actor, we asked people to rate the importance of various goals. To recruit the self-as-agent, we asked people to describe their goals verbally. In Study 1, actors claimed their goals were equally about helping the self and others (viz., moral); agents claimed their goals were primarily about helping the self (viz., selfish). This disparity was evident in both individualist and collectivist cultures, attesting to the universality of the selfish agent. Study 2 compared actors' and agents' motives to those of people role-playing highly prosocial or selfish exemplars. In content (Study 2a) and in the impressions they made on an outside observer (Study 2b), actors' motives were similar to those of the prosocial role-players, whereas agents' motives were similar to those of the selfish role-players. Study 3 accounted for the difference between the actor and agent: Participants claimed that their agent's motives were the more realistic and that their actor's motives were the more idealistic. The selfish agent/moral actor duality may account for why implicit and explicit measures of the same construct diverge, and why feeling watched brings out the better angels of human nature.

    2010-11-01

    Full Text Available This paper presents the results of a research aimed at explaining the system of interactions of social actors in Public Communication of Science and Technology (PCST, in the context of a social web defined by the novel systems of communication sustained on informational and communication technologies. The study’s theoretical framework highlights the strategic importance of a Public Communication  which focuses on promoting public appropriation of Science and Technology, going beyond the role of Journalism and Science Communication that informs a qualified public, to one that stablishes a bond with policies and decision making in the area, made with participation of international agencies, governments, producers of science and technology, journalists’ associations, educational institutions, and citizens. The research relies on Explicative Methodology. A revision of pertinent bibliography leads to the conclusion that the system of social interactions mediated by personal, interpersonal and grupal global communications, define the relationships in the communicational exchange of the social actor with regard to public communication of science and technology and policies aimed at its appropriation.

We provide a number of examples to show the usefulness of the extension. We also explore the design space for multi-headed message matching semantics, for example first-match......The actor model provides high-level concurrency abstractions to coordinate simultaneous computations by message passing. Languages implementing the actor model such as Erlang commonly only support single-headed pattern matching over received messages. We propose and design an extension of Erlang...... and rule priority-match semantics. The various semantics are inspired by the multi-set constraint matching semantics found in Constraint Handling Rules. This provides us with a formal model to study actors with multi-headed message receive patterns. The system can be implemented efficiently and we have...

    Full Text Available Research question: We are looking at the process of structuring an integrated care system as an innovative process that swings back and forth between the diversity of the actors involved, local aspirations and national and regional regulations. We believe that innovation is enriched by the variety of the actors involved, but may also be blocked or disrupted by that diversity. Our research aims to add to other research, which, when questioning these integrated systems, analyses how the actors involved deal with diversity without really questioning it. Case study: The empirical basis of the paper is provided by case study analysis. The studied integrated care system is a French healthcare network that brings together healthcare professionals and various organisations in order to improve the way in which interventions are coordinated and formalised, in order to promote better detection and diagnosis procedures and the implementation of a care protocol. We consider this case as instrumental in developing theoretical proposals for structuring an integrated care system in light of the diversity of the actors involved. Results and discussion: We are proposing a model for structuring an integrated care system in light of the enacted diversity of the actors involved. This model is based on three factors: the diversity enacted by the leaders, three stances for considering the contribution made by diversity in the structuring process and the specific leading role played by those in charge of the structuring process.  Through this process, they determined how the actors involved in the project were differentiated, and on what basis those actors were involved. By mobilizing enacted diversity, the leaders are seeking to channel the emergence of a network in light of their own representation of that network. This model adds to published research on the structuring of integrated care systems.

    O'Brien, Paula

    2013-09-01

    Most health systems have historically used a mix of public and private actors for financing and delivering care. But the last 30 years have seen many rich and middle-income countries moving to privatise parts of their health care systems. This phenomenon has generated concerns, especially about equitable access to health care. This article examines what the international right to the highest attainable standard of health in Art 12 of the International Covenant on Economic, Social and Cultural Rights says about the obligations of states which use private actors in health care. The article involves a close study of the primary documents of the key institutions responsible for interpreting and promoting Art 12. From this study, the article concludes that in mixed public-private health care systems, states not only retain primary responsibility for fulfilling the right to health but are subject to a range of additional specific responsibilities.

    Urbanization, climate uncertainty, and ecosystem change represent major challenges for managing water resources. Water systems and the forces acting upon them are complex, and there is a need to understand and generically represent the most important system components and linkages. We developed a framework to facilitate understanding of water systems including potential vulnerabilities and opportunities for sustainability. Our goal was to produce an interdisciplinary framework for water resources research to address water issues across scales (e.g., city to region) and domains (e.g., water supply and quality, urban and transitioning landscapes). An interdisciplinary project (iUTAH - innovative Urban Transitions and Aridregion Hydro-sustainability) with a large (N=~100), diverse team having expertise spanning the hydrologic, biological, ecological, engineering, social, planning, and policy sciences motivated the development of this framework. The framework was developed through review of the literature, meetings with individual researchers, and workshops with participants. The Structure-Water-Actor Framework (SWAF) includes three main components: water (quality and quantity), structure (natural, built, and social), and actors (individual and organizational). Key linkages include: 1) ecological and hydrological processes, 2) ecosystem and geomorphic change, 3) planning, design, and policy, 4) perceptions, information, and experience, 5) resource access, and 6) operational water use and management. Our expansive view of structure includes natural, built, and social components, allowing us to examine a broad set of tools and levers for water managers and decision-makers to affect system sustainability and understand system outcomes. We validate the SWAF and illustrate its flexibility to generate insights for three research and management problems: green stormwater infrastructure in an arid environment, regional water supply and demand, and urban river restoration

    Worldwide, there are competing norms driving health system changes and reorganisation. One such norm is that of health systems' responsibilities for population health as distinct from a focus on clinical services. In this paper we report on a case study of population health planning in Australian primary health care (PHC) organisations (Medicare Locals, 2011-2015). Drawing on institutional theory, we describe how institutional forces, ideas and actors shaped such planning. We reviewed the planning documents of the 61 Medicare Locals and rated population health activities in each Medicare Local. We also conducted an online survey and 50 interviews with Medicare Local senior staff, and an interview and focus group with Federal Department of Health staff. Despite policy emphasis on population health, Medicare Locals reported higher levels of effort and capacity in providing clinical services. Health promotion and social determinants of health activities were undertaken on an ad hoc basis. Regulatory conditions imposed by the federal government including funding priorities and time schedules, were the predominant forces constraining population health planning. In some Medicare Locals, this was in conflict with the normative values and what Medicare Locals felt ought to be done. The alignment between the governmental and the cultural-cognitive forces of a narrow biomedical approach privileged clinical practice and ascribed less legitimacy to action on social determinants of health. Our study also shed light on the range of PHC actors and how their agency influenced Medicare Locals' performance in population health. The presence of senior staff or community boards with a strong commitment to population health were important in directing action towards population health and equity. There are numerous institutional, normative and cultural factors influencing population health planning. The experience of Australian Medicare Locals highlights the difficulties of planning in

  3. Adaptive Inverse Optimal Control for Rehabilitation Robot Systems Using Actor-Critic Algorithm

    2014-01-01

    Full Text Available The higher goal of rehabilitation robot is to aid a person to achieve a desired functional task (e.g., tracking trajectory based on assisted-as-needed principle. To this goal, a new adaptive inverse optimal hybrid control (AHC combining inverse optimal control and actor-critic learning is proposed. Specifically, an uncertain nonlinear rehabilitation robot model is firstly developed that includes human motor behavior dynamics. Then, based on this model, an open-loop error system is formed; thereafter, an inverse optimal control input is designed to minimize the cost functional and a NN-based actor-critic feedforward signal is responsible for the nonlinear dynamic part contaminated by uncertainties. Finally, the AHC controller is proven (through a Lyapunov-based stability analysis to yield a global uniformly ultimately bounded stability result, and the resulting cost functional is meaningful. Simulation and experiment on rehabilitation robot demonstrate the effectiveness of the proposed control scheme.

  4. An Erlang Implementation of Multiparty Session Actors

    Directory of Open Access Journals (Sweden)

    Simon Fowler

    2016-08-01

    Full Text Available By requiring co-ordination to take place using explicit message passing instead of relying on shared memory, actor-based programming languages have been shown to be effective tools for building reliable and fault-tolerant distributed systems. Although naturally communication-centric, communication patterns in actor-based applications remain informally specified, meaning that errors in communication are detected late, if at all. Multiparty session types are a formalism to describe, at a global level, the interactions between multiple communicating entities. This article describes the implementation of a prototype framework for monitoring Erlang/OTP gen_server applications against multiparty session types, showing how previous work on multiparty session actors can be adapted to a purely actor-based language, and how monitor violations and termination of session participants can be reported in line with the Erlang mantra of "let it fail". Finally, the framework is used to implement two case studies: an adaptation of a freely-available DNS server, and a chat server.

    Full Text Available Social norms have traditionally been difficult to quantify. In any particular society, their sheer number and complex interdependencies often limit a system-level analysis. One exception is that of the network of norms that sustain the online Wikipedia community. We study the fifteen-year evolution of this network using the interconnected set of pages that establish, describe, and interpret the community’s norms. Despite Wikipedia’s reputation for ad hoc governance, we find that its normative evolution is highly conservative. The earliest users create norms that both dominate the network and persist over time. These core norms govern both content and interpersonal interactions using abstract principles such as neutrality, verifiability, and assume good faith. As the network grows, norm neighborhoods decouple topologically from each other, while increasing in semantic coherence. Taken together, these results suggest that the evolution of Wikipedia’s norm network is akin to bureaucratic systems that predate the information age.

    Policy analysts love solving complex problems. Their favorite problems are not just technically complex but also characterized by the presence of many different social actors that hold conflicting interests, objectives, and perceptions and act strategically to get the best out of a problem situation. This book offers guidance for policy analysts who want to assess if and how their analysis could be of help, based on the premise that problem formulation is the cornerstone in addressing complex problems. This book positions policy analysis within the theories on processes of policy making, and f

    Actor-critic methods solve reinforcement learning problems by updating a parameterized policy known as an actor in a direction that increases an estimate of the expected return known as a critic. However, existing actor-critic methods only use values or gradients of the critic to update the policy parameter. In this paper, we propose a novel actor-critic method called the guide actor-critic (GAC). GAC firstly learns a guide actor that locally maximizes the critic and then it updates the polic...

  10. T-S Fuzzy Model-Based Approximation and Filter Design for Stochastic Time-Delay Systems with Hankel Norm Criterion

    2014-01-01

    Full Text Available This paper investigates the Hankel norm filter design problem for stochastic time-delay systems, which are represented by Takagi-Sugeno (T-S fuzzy model. Motivated by the parallel distributed compensation (PDC technique, a novel filtering error system is established. The objective is to design a suitable filter that guarantees the corresponding filtering error system to be mean-square asymptotically stable and to have a specified Hankel norm performance level γ. Based on the Lyapunov stability theory and the Itô differential rule, the Hankel norm criterion is first established by adopting the integral inequality method, which can make some useful efforts in reducing conservativeness. The Hankel norm filtering problem is casted into a convex optimization problem with a convex linearization approach, which expresses all the conditions for the existence of admissible Hankel norm filter as standard linear matrix inequalities (LMIs. The effectiveness of the proposed method is demonstrated via a numerical example.

    Health systems are social institutions, in which health worker performance is shaped by transactional processes between different actors.This analytical assessment unravels the complex web of factors that influence the performance of community health workers (CHWs) in low- and middle-income countries. It examines their unique intermediary position between the communities they serve and actors in the health sector, and the complexity of the health systems in which they operate. The assessment combines evidence from the international literature on CHW programmes with research outcomes from the 5-year REACHOUT consortium, undertaking implementation research to improve CHW performance in six contexts (two in Asia and four in Africa). A conceptual framework on CHW performance, which explicitly conceptualizes the interface role of CHWs, is presented. Various categories of factors influencing CHW performance are distinguished in the framework: the context, the health system and intervention hardware and the health system and intervention software. Hardware elements of CHW interventions comprise the supervision systems, training, accountability and communication structures, incentives, supplies and logistics. Software elements relate to the ideas, interests, relationships, power, values and norms of the health system actors. They influence CHWs' feelings of connectedness, familiarity, self-fulfilment and serving the same goals and CHWs' perceptions of support received, respect, competence, honesty, fairness and recognition.The framework shines a spotlight on the need for programmes to pay more attention to ideas, interests, relationships, power, values and norms of CHWs, communities, health professionals and other actors in the health system, if CHW performance is to improve.

  12. European Top Managers' Age-Related Workplace Norms and Their Organizations' Recruitment and Retention Practices Regarding Older Workers.

    2017-10-01

    Top managers guide organizational strategy and practices, but their role in the employment of older workers is understudied. We study the effects that age-related workplace norms of top managers have on organizations' recruitment and retention practices regarding older workers. We investigate two types of age-related workplace norms, namely age equality norms (whether younger and older workers should be treated equally) and retirement age norms (when older workers are expected to retire) while controlling for organizational and national contexts. Data collected among top managers of 1,088 organizations from six European countries were used for the study. Logistic regression models were run to estimate the effects of age-related workplace norms on four different organizational outcomes: (a) recruiting older workers, (b) encouraging working until normal retirement age, (c) encouraging working beyond normal retirement age, and (d) rehiring retired former employees. Age-related workplace norms of top managers affect their organizations' practices, but in different ways. Age equality norms positively affect practices before the boundary of normal retirement age (Outcomes a and b), whereas retirement age norms positively affect practices after the boundary of normal retirement age (Outcomes c and d). Changing age-related workplace norms of important actors in organizations may be conducive to better employment opportunities and a higher level of employment participation of older workers. However, care should be taken to target the right types of norms, since targeting different norms may yield different outcomes. © The Author 2016.

  14. The salience of social referents: a field experiment on collective norms and harassment behavior in a school social network.

    Science.gov (United States)

    Paluck, Elizabeth Levy; Shepherd, Hana

    2012-12-01

    Persistent, widespread harassment in schools can be understood as a product of collective school norms that deem harassment, and behavior allowing harassment to escalate, as typical and even desirable. Thus, one approach to reducing harassment is to change students' perceptions of these collective norms. Theory suggests that the public behavior of highly connected and chronically salient actors in a group, called social referents, may provide influential cues for individuals' perception of collective norms. Using repeated, complete social network surveys of a public high school, we demonstrate that changing the public behavior of a randomly assigned subset of student social referents changes their peers' perceptions of school collective norms and their harassment behavior. Social referents exert their influence over peers' perceptions of collective norms through the mechanism of everyday social interaction, particularly interaction that is frequent and personally motivated, in contrast to interaction shaped by institutional channels like shared classes. These findings clarify the development of collective social norms: They depend on certain patterns of and motivations for social interactions within groups across time, and are not static but constantly reshaped and reproduced through these interactions. Understanding this process creates opportunities for changing collective norms and behavior. (PsycINFO Database Record (c) 2012 APA, all rights reserved).

  15. Importance of Actors and Agency in Sustainability Transitions: A Systematic Exploration of the Literature

    Directory of Open Access Journals (Sweden)

    Lisa-Britt Fischer

    2016-05-01

    Full Text Available This article explores the role of actors and agency in the literature on sustainability transitions. We reviewed 386 journal articles on transition management and sustainability transitions listed in Scopus from 1995 to 2014. We investigate the thesis that actors have been neglected in this literature in favor of more abstract system concepts. Results show that this thesis cannot be confirmed on a general level. Rather, we find a variety of different approaches, depending on the systemic level, for clustering actors and agency as niche, regime, and landscape actors; the societal realm; different levels of governance; and intermediaries. We also differentiate between supporting and opposing actors. We find that actor roles in transitions are erratic, since their roles can change over the course of time, and that actors can belong to different categories. We conclude by providing recommendations for a comprehensive typology of actors in sustainability transitions.

    Ancient Athens was a remarkably peaceful and well-ordered society by both ancient and contemporary standards. Scholars typically attribute Athens’ success to internalized norms and purely informal enforcement mechanisms.

    2017-03-01

    Although various norms for reciprocity-based cooperation have been suggested that are evolutionarily stable against invasion from free riders, the process of alternation of norms and the role of diversified norms remain unclear in the evolution of cooperation. We clarify the co-evolutionary dynamics of norms and cooperation in indirect reciprocity and also identify the indispensable norms for the evolution of cooperation. Inspired by the gene knockout method, a genetic engineering technique, we developed the norm knockout method and clarified the norms necessary for the establishment of cooperation. The results of numerical investigations revealed that the majority of norms gradually transitioned to tolerant norms after defectors are eliminated by strict norms. Furthermore, no cooperation emerges when specific norms that are intolerant to defectors are knocked out.

  18. H∞ Loop Shaping Control of Input Saturated Systems with Norm-Bounded Parametric Uncertainty

    Directory of Open Access Journals (Sweden)

    Renan Lima Pereira

    2015-01-01

    Full Text Available This paper proposes a gain-scheduling control design strategy for a class of linear systems with the presence of both input saturation constraints and norm-bounded parametric uncertainty. LMI conditions are derived in order to obtain a gain-scheduled controller that ensures the robust stability and performance of the closed loop system. The main steps to obtain such a controller are given. Differently from other gain-scheduled approaches in the literature, this one focuses on the problem of H∞ loop shaping control design with input saturation nonlinearity and norm-bounded uncertainty to reduce the effect of the disturbance input on the controlled outputs. Here, the design problem has been formulated in the four-block H∞ synthesis framework, in which it is possible to describe the parametric uncertainty and the input saturation nonlinearity as perturbations to normalized coprime factors of the shaped plant. As a result, the shaped plant is represented as a linear parameter-varying (LPV system while the norm-bounded uncertainty and input saturation are incorporated. This procedure yields a linear parameter-varying structure for the controller that ensures the stability of the polytopic LPV shaped plant from the vertex property. Finally, the effectiveness of the method is illustrated through application to a physical system: a VTOL “vertical taking-off landing” helicopter.

    2015-03-01

    Full Text Available The current study aims at identifying particular ways through which social actors are represented in Summit Series ELT textbooks. It examines cultural load in the textbooks within critical discourse analysis framework, in this case van Leeuwen’s framework. Particularly, the study attempts to explore if values, norms, and roles are culture/context-bound. Results of the analyses showed that among discursive features, Inclusion, Genericization, and Indetermination were used more than Exclusion, Specification, and Determination. Activation was more observed than Passivation, and Categorization had an important function in the representation of some of the social actors along with Assimilation and Impersonalization. The analysis also indicated the impartiality toward the representation of social actors. Moral, social, and personal values were the most disseminated values, while social morality and traditions had the highest occurrence. However, a few discriminative cases were found regarding gender roles. The researchers proposed that Summit Series were less grounded in cultural assumptions/biases. This impartiality eases language learning by keeping learners away from misunderstanding and incomprehensibility.

  4. Proposal for Requirement Validation Criteria and Method Based on Actor Interaction

    Hattori, Noboru; Yamamoto, Shuichiro; Ajisaka, Tsuneo; Kitani, Tsuyoshi

    We propose requirement validation criteria and a method based on the interaction between actors in an information system. We focus on the cyclical transitions of one actor's situation against another and clarify observable stimuli and responses based on these transitions. Both actors' situations can be listed in a state transition table, which describes the observable stimuli or responses they send or receive. Examination of the interaction between both actors in the state transition tables enables us to detect missing or defective observable stimuli or responses. Typically, this method can be applied to the examination of the interaction between a resource managed by the information system and its user. As a case study, we analyzed 332 requirement defect reports of an actual system development project in Japan. We found that there were a certain amount of defects regarding missing or defective stimuli and responses, which can be detected using our proposed method if this method is used in the requirement definition phase. This means that we can reach a more complete requirement definition with our proposed method.

  5. What is a conservation actor?

    Directory of Open Access Journals (Sweden)

    Paul Jepson

    2011-01-01

    Full Text Available As a crisis-oriented discipline, conservation biology needs actions to understand the state of nature and thwart declines in biodiversity. Actors-traditionally individuals, institutions, and collectives-have been central to delivering such goals in practice. However, the definition of actors within the discipline has been narrow and their role in influencing conservation outcomes inadequately conceptualised. In this paper, we examine the question ′What is a conservation actor?′ Who or what creates the capacity to influence conservation values and actions? Drawing from theoretical developments in Actor-Network Theory and collective governance, we argue that the concept of an actor in conservation biology should be broadened to include non-humans, such as species and devices, because they have the agency and ability to influence project goals and outcomes. We illustrate this through four examples: the Asian elephant, International Union for Conservation of Nature red lists, the High Conservation Value approach, and an Integrated Conservation and Development Project. We argue that a broader conceptualisation of actors in conservation biology will produce new forms of understanding that could open up new areas of conservation research, enhance practice and draw attention to spheres of conservation activity that might require stronger oversight and governance.

As an alternative, the term "noteworthy actors" is used and a brief review of them in Latin America is presented. The relevant question should address the social scenarios from where these actors can express themselves. A preliminary distinction of scenarios is presented, in which old and new social movements could be integrated and relationships of articulation and equivalence could be established.

  9. Agenda setting for maternal survival: the power of global health networks and norms.

    Science.gov (United States)

    Smith, Stephanie L; Rodriguez, Mariela A

    2016-04-01

    Nearly 300,000 women--almost all poor women in low-income countries--died from pregnancy-related complications in 2010. This represents a decline since the 1980s, when an estimated half million women died each year, but is still far higher than the aims set in the United Nations Millennium Development Goals (MDGs) at the turn of the century. The 1970s, 1980s and 1990 s witnessed a shift from near complete neglect of the issue to emergence of a network of individuals and organizations with a shared concern for reducing maternal deaths and growth in the number of organizations and governments with maternal health strategies and programmes. Maternal health experienced a marked change in agenda status in the 2000s, attracting significantly higher level attention (e.g. from world leaders) and greater resource commitments (e.g. as one issue addressed by US$40 billion in pledges to the 2010 Global Strategy for Women's and Children's Health) than ever before. Several differences between network and actor features, issue characteristics and the policy environment pre- and post-2000 help to explain the change in agenda status for global maternal mortality reduction. Significantly, a strong poverty reduction norm emerged at the turn of the century; represented by the United Nations MDGs framework, the norm set unusually strong expectations for international development actors to advance included issues. As the norm grew, it drew policy attention to the maternal health goal (MDG 5). Seeking to advance the goals agenda, world leaders launched initiatives addressing maternal and child health. New network governance and framing strategies that closely linked maternal, newborn and child health shaped the initiatives. Diverse network composition--expanding beyond a relatively narrowly focused and technically oriented group to encompass allies and leaders that brought additional resources to bear on the problem--was crucial to maternal health's rise on the agenda in the 2000s

    Social norms are often cited as the cause of many social phenomena, especially as an explanation for prosocial family and relationship behaviors. And yet maybe we love the idea of social norms too much, as suggested by our failure to subject them to rigorous test. Compared to the detail in social norms theoretical orientations, there is very little detail in tests of normative theories. To provide guidance to researchers who invoke social norms as explanations, we catalog normative orientations that have been proposed to account for consistent patterns of action. We call on researchers to conduct tests of normative theories and the processes such theories assert.

  14. Trail-Based Search for Efficient Event Report to Mobile Actors in Wireless Sensor and Actor Networks.

    Xu, Zhezhuang; Liu, Guanglun; Yan, Haotian; Cheng, Bin; Lin, Feilong

    2017-10-27

    In wireless sensor and actor networks, when an event is detected, the sensor node needs to transmit an event report to inform the actor. Since the actor moves in the network to execute missions, its location is always unavailable to the sensor nodes. A popular solution is the search strategy that can forward the data to a node without its location information. However, most existing works have not considered the mobility of the node, and thus generate significant energy consumption or transmission delay. In this paper, we propose the trail-based search (TS) strategy that takes advantage of actor's mobility to improve the search efficiency. The main idea of TS is that, when the actor moves in the network, it can leave its trail composed of continuous footprints. The search packet with the event report is transmitted in the network to search the actor or its footprints. Once an effective footprint is discovered, the packet will be forwarded along the trail until it is received by the actor. Moreover, we derive the condition to guarantee the trail connectivity, and propose the redundancy reduction scheme based on TS (TS-R) to reduce nontrivial transmission redundancy that is generated by the trail. The theoretical and numerical analysis is provided to prove the efficiency of TS. Compared with the well-known expanding ring search (ERS), TS significantly reduces the energy consumption and search delay.

    To analyse the role of Mexico's mental health system governance in the development of mental health policies and programmes, from the perspective of its own actors. A map was developed for identifying the actors in Mexico's mental health system. A guide was designed for in-depth interviews, which were recorded and arranged in categories for their analysis. The Atlas-ti v.7 software was used for the organisation of qualitative data and Policy Maker v.4 was used to determine the position and influence of actors within the health system. The actors were identified according to their level of influence in mental health policies: high, medium and low. Actors with a high level of influence participate in national policies, actors with medium influence are involved in regional or local policies and the participation of actors with a low level of influence is considered marginal. This study facilitated understanding of governance in mental health. The level of influence of the actors directly affects the scope of governance indicators. Relevant data were obtained to improve policies in mental health care. Copyright © 2016 SESPAS. Publicado por Elsevier España, S.L.U. All rights reserved.

These activities are subject to declaration to the Belgian radiation protection authority (Federal Agency for Nuclear Control - FANC). The initial list was subsequently modified by a FANC decree in 2012 to reflect the increased knowledge about NORM in other industrial sectors, most of which have also been added in the recently published New Basic Safety Standards (Directive 2013/53/EURATOM). In March 2013, an additional decree was published by FANC regulating the acceptance of NORM residues by non-radioactive waste treatment facilities. This regulation was fitted within the framework described above by introducing NORM residue treatment into the existing NORM industry list. It introduces generic exemption levels above which the processing or disposal of NORM residues will be considered as a 'work activity' and submitted to declaration according to the Belgian radiation protection regulations. On basis of this declaration, specific acceptance criteria are assigned to the disposal or processing facility. FANC has published technical and methodological guides for the operators of the concerned facilities and industries to facilitate the declaration process, and has recently organized a round-table gathering both NORM industries and waste processing industries to identify the needs, uncertainties and concerns regarding the regulatory control of NORM in Belgium.

    Full Text Available Nowadays, the world seems to be in a transition from the current system founded on the liberal social, economic and political model to a more diverse and heterogeneous model in which the determinant role is played by a number of state and non-state actors. The step from the Western system of cultural, political and predominant economic values to a more diverse and heterogeneous system makes the actors involved defend not only their visions, but also promote their own interests. The differences between visions gain relevance and clarity because the countries supporting them obtain increased power, and that is more than obvious. All this leads to a symmetric allocation of different means, which generates uncertainties and diminishes unilateral actions This transition process impacts global security especially through the asymmetric, unconventional and hybrid risks and threats manifesting worldwide.

  4. The consequences of the heterosexual norm

    Full Text Available Librarians may exclude people accidentally. This is so because there is a widespread use of classifications and subject headings reflecting the heterosexual norm. Critical classification theory tackles this norm for the reason that it affects the retrieval of gay literature. In order to allow a reconsideration of this exclusive practice in the LIS community I challenge two main questions: Firstly, how does the heterosexual norm appear in classification systems and subject headings lists? And secondly, what are the consequences of that practice for the retrieval of gay literature?This paper focuses on the professional practise in Swedish public libraries. If subject cataloguing prevents Lesbians, Gays, Bisexuals and Transgender (LGBT finding their literatures, then Swedish public libraries are upholders of the exclusive heterosexual norm in society.

  7. Vitrification of NORM wastes

    Chapman, C.

    1994-05-01

    Vitrification of wastes is a relatively new application of none of man's oldest manufacturing processes. During the past 25 years it has been developed and accepted internationally for immobilizing the most highly radioactive wastes from spent nuclear fuel. By the year 2005, there will be nine operating high-level radioactive vitrification plants. Many of the technical ''lessons learned'' from this international program can be applied to much less hazardous materials such as naturally occurring radioactive material (NORM). With the deployment of low capital and operating cost systems, vitrification should become a broadly applied process for treating a large variety of wastes. In many situations, the wastes can be transformed into marketable products. This paper will present a general description of waste vitrification, summarize some of its key advantages, provide some test data for a small sample of one NORM, and suggest how this process may be applied to NORM

  8. Quasi-invariant modified Sobolev norms for semi linear reversible PDEs

    International Nuclear Information System (INIS)

    Faou, Erwan; Grébert, Benoît

    2010-01-01

    We consider a general class of infinite dimensional reversible differential systems. Assuming a nonresonance condition on linear frequencies, we construct for such systems almost invariant pseudo-norms that are close to Sobolev-like norms. This allows us to prove that if the Sobolev norm of index s of the initial data z 0 is sufficiently small (of order ε) then the Sobolev norm of the solution is bounded by 2ε over a very long time interval (of order ε −r with r arbitrary). It turns out that this theorem applies to a large class of reversible semi-linear partial differential equations (PDEs) including the nonlinear Schrödinger (NLS) equation on the d-dimensional torus. We also apply our method to a system of coupled NLS equations which is reversible but not Hamiltonian. We also note that for the same class of reversible systems we can prove a Birkhoff normal form theorem, which in turn implies the same bounds on the Sobolev norms. Nevertheless the techniques that we use to prove the existence of quasi-invariant pseudo-norms are much more simple and direct

    This paper addresses the problem of spatiotemporal localization of actions in videos. Compared to leading approaches, which all learn to localize based on carefully annotated boxes on training video frames, we adhere to a weakly-supervised solution that only requires a video class label. We introduce an actor-supervised architecture that exploits the inherent compositionality of actions in terms of actor transformations, to localize actions. We make two contributions. First, we propose actor proposals derived from a detector for human and non-human actors intended for images, which is linked over time by Siamese similarity matching to account for actor deformations. Second, we propose an actor-based attention mechanism that enables the localization of the actions from action class labels and actor proposals and is end-to-end trainable. Experiments on three human and non-human action datasets show actor supervision is state-of-the-art for weakly-supervised action localization and is even competitive to some fully-supervised alternatives.

    The probability of income loss depends on talent and effort. Effort has positive externalities and therefore individuals are proportion to their perceived diligence. The social norm requires more effort from individuals perceived as more talented, but talent is private information and individuals cunningly choose effort so as to manipulate the public perception of their talent. We analyze the workings of a social insurance system in this setting. It turns out that social norms may mitigate mo...

The performance index allows us also to optimize the structure of the fault detection filter directly...

  15. Management of NORM Residues

    International Nuclear Information System (INIS)

    2013-06-01

    The IAEA attaches great importance to the dissemination of information that can assist Member States in the development, implementation, maintenance and continuous improvement of systems, programmes and activities that support the nuclear fuel cycle and nuclear applications, and that address the legacy of past practices and accidents. However, radioactive residues are found not only in nuclear fuel cycle activities, but also in a range of other industrial activities, including: - Mining and milling of metalliferous and non-metallic ores; - Production of non-nuclear fuels, including coal, oil and gas; - Extraction and purification of water (e.g. in the generation of geothermal energy, as drinking and industrial process water; in paper and pulp manufacturing processes); - Production of industrial minerals, including phosphate, clay and building materials; - Use of radionuclides, such as thorium, for properties other than their radioactivity. Naturally occurring radioactive material (NORM) may lead to exposures at some stage of these processes and in the use or reuse of products, residues or wastes. Several IAEA publications address NORM issues with a special focus on some of the more relevant industrial operations. This publication attempts to provide guidance on managing residues arising from different NORM type industries, and on pertinent residue management strategies and technologies, to help Member States gain perspectives on the management of NORM residues

  16. Switched periodic systems in discrete time: stability and input-output norms

    Science.gov (United States)

    Bolzern, Paolo; Colaneri, Patrizio

    2013-07-01

    This paper deals with the analysis of stability and the characterisation of input-output norms for discrete-time periodic switched linear systems. Such systems consist of a network of time-periodic linear subsystems sharing the same state vector and an exogenous switching signal that triggers the jumps between the subsystems. The overall system exhibits a complex dynamic behaviour due to the interplay between the time periodicity of the subsystem parameters and the switching signal. Both arbitrary switching signals and signals satisfying a dwell-time constraint are considered. Linear matrix inequality conditions for stability and guaranteed H2 and H∞ performances are provided. The results heavily rely on the merge of the theory of linear periodic systems and recent developments on switched linear time-invariant systems.

    Interventions using either contests or norms can promote environmental behavioral change. Yet research on the implications of contest-based and norm-based interventions is lacking. Based on Goal-framing theory, we suggest that a contest-based intervention frames a gain goal promoting intensive but instrumental behavioral engagement. In contrast, the norm-based intervention was expected to frame a normative goal activating normative obligations for targeted and non-targeted behavior and motivation to engage in pro-environmental behaviors in the future. In two studies participants ( n = 347) were randomly assigned to either a contest- or a norm-based intervention technique. Participants in the contest showed more intensive engagement in both studies. Participants in the norm-based intervention tended to report higher intentions for future energy conservation (Study 1) and higher personal norms for non-targeted pro-environmental behaviors (Study 2). These findings suggest that contest-based intervention technique frames a gain goal, while norm-based intervention frames a normative goal.

    Basing on fundamental idea of dynamical chaos and strict periodicity in living systems the new peculiarities in brain and heart functioning have been reveled. It has been shown that the development of pathological states of brain and heart activities occurs by means of both increase and decrease of chaos components in brain activity and heart rhythm. It has been defined the 'health range' for brain and heart functioning in norm, and the method of recovery of the health range is proposed from the electrocardiograms and electroencephalograms data (authors).

  20. Extended mind and after: socially extended mind and actor-network.

    Science.gov (United States)

    Kono, Tetsuya

    2014-03-01

    The concept of extended mind has been impressively developed over the last 10 years by many philosophers and cognitive scientists. The extended mind thesis (EM) affirms that the mind is not simply ensconced inside the head, but extends to the whole system of brain-body-environment. Recently, some philosophers and psychologists try to adapt the idea of EM to the domain of social cognition research. Mind is socially extended (SEM). However, EM/SEM theory has problems to analyze the interactions among a subject and its surroundings with opposition, antagonism, or conflict; it also tends to think that the environment surrounding the subject is passive or static, and to neglect the power of non-human actants to direct and regulate the human subject. In these points, actor-network theory (ANT) proposed by Latour and Callon is more persuasive, while sharing some important ideas with EM/SEM theory. Actor-network is a hybrid community which is composed of a series of heterogeneous elements, animate and inanimate for a certain period of time. I shall conclude that EM/SEM could be best analyzed as a special case of actor-network. EM/SEM is a system which can be controlled by a human agent alone. In order to understand collective behavior, philosophy and psychology have to study the actor-network in which human individuals are situated.

    Full Text Available The argument that the minimization of the dysfunctional consequences of organizational politics is no longer dependent on self-equilibrating mechanism remains valid. This inquiry is therefore framed with a view to establishing suitable strategies for managing political actors. There is a nexus between the diagnosis typology of political actors and the qualitative classes of political actors and their management strategies. In the management of mixed blessing, supportive, non-supportive and marginal political actors; collaborative, involvement, defensive and information strategies respectively were found suitable. This research is based on existing theoretical knowledge on organizational politics and stakeholders management. Data was collected from the literature by means of critical analysis and dialectic reflection on the emerging themes. The study will enhance capability in contexts where the scientific management of political actors is yet to be exemplified.

    Full Text Available The fruitfulness and the necessity of the distinction between values and norms and as principles are investigated by way of the theory of political development, the legal philosophical issue surrounding natural law and positivism and the views of Habermas. In political developmental theory questions centring on value gained legitimate relevancy under the influ­ ence of the post-behaviorist approach. The quest for cultural universalia or values as principles became important in this sphere because it seems to be the only way to escape from the syndrome of modernity. Through the rejection of the oppositions and one-sidedness of legal positivism and natural law and with the aid of the distinction between values, norms and principles the productive contribution of this spurious dilemma is high­ lighted and a clearer delineation is given of the concepts legal develop­ ment and structural violence. In conclusion Habermas's distinction between norms and meta-norms is investigated critically and immanent contradictions in his views are pointed out. The central place which this issue has in his thought can be seen as a confirmation of the importance of this distinction. It is relevant for all the normative disciplines which - in contrast to the natural sciences - focus on the role of linguistic, social, ethical, legal and artistic norms valid for human societies.

    Mid-level health workers are on the front-lines in underserved areas in many LMICs, and their performance is critical for improving the health of vulnerable populations. However, improving performance in low-resource settings is complex and highly dependent on the organizational context of local health systems. This study aims to examine the views of actors from different levels of a regional health system in Guatemala on actions to support the performance of auxiliary nurses, a cadre of mid-level health workers with a prominent role in public sector service delivery. A concept mapping study was carried out to develop an integrated view on organizational support and identify locally relevant strategies for strengthening performance. A total of 93 regional and district managers, and primary and secondary care health workers participated in generating ideas on actions needed to support auxiliary nurses' performance. Ideas were consolidated into 30 action items, which were structured through sorting and rating exercises, involving a total of 135 of managers and health workers. Maps depicting participants' integrated views on domains of action and dynamics in sub-groups' interests were generated using a sequence of multivariate statistical analyses, and interpreted by regional managers. The combined input of health system actors provided a multi-faceted view of actions needed to support performance, which were organized in six domains, including: Communication and coordination, Tools to orient work, Organizational climate of support, Motivation through recognition, Professional development and Skills development. The nature of relationships across hierarchical levels was identified as a cross-cutting theme. Pattern matching and go-zone maps indicated directions for action based on areas of consensus and difference across sub-groups of actors. This study indicates that auxiliary nurses' performance is interconnected with the performance of other health system actors who

    Webster, Michael A.; Yasuda, Maiko; Haber, Sara; Leonard, Deanne; Ballardini, Nicole

    2007-02-01

    We used adaptation to examine the relationship between perceptual norms--the stimuli observers describe as psychologically neutral, and response norms--the stimulus levels that leave visual sensitivity in a neutral or balanced state. Adapting to stimuli on opposite sides of a neutral point (e.g. redder or greener than white) biases appearance in opposite ways. Thus the adapting stimulus can be titrated to find the unique adapting level that does not bias appearance. We compared these response norms to subjectively defined neutral points both within the same observer (at different retinal eccentricities) and between observers. These comparisons were made for visual judgments of color, image focus, and human faces, stimuli that are very different and may depend on very different levels of processing, yet which share the property that for each there is a well defined and perceptually salient norm. In each case the adaptation aftereffects were consistent with an underlying sensitivity basis for the perceptual norm. Specifically, response norms were similar to and thus covaried with the perceptual norm, and under common adaptation differences between subjectively defined norms were reduced. These results are consistent with models of norm-based codes and suggest that these codes underlie an important link between visual coding and visual experience.

  8. Trail-Based Search for Efficient Event Report to Mobile Actors in Wireless Sensor and Actor Networks †

    Xu, Zhezhuang; Liu, Guanglun; Yan, Haotian; Cheng, Bin; Lin, Feilong

    2017-01-01

    In wireless sensor and actor networks, when an event is detected, the sensor node needs to transmit an event report to inform the actor. Since the actor moves in the network to execute missions, its location is always unavailable to the sensor nodes. A popular solution is the search strategy that can forward the data to a node without its location information. However, most existing works have not considered the mobility of the node, and thus generate significant energy consumption or transmission delay. In this paper, we propose the trail-based search (TS) strategy that takes advantage of actor’s mobility to improve the search efficiency. The main idea of TS is that, when the actor moves in the network, it can leave its trail composed of continuous footprints. The search packet with the event report is transmitted in the network to search the actor or its footprints. Once an effective footprint is discovered, the packet will be forwarded along the trail until it is received by the actor. Moreover, we derive the condition to guarantee the trail connectivity, and propose the redundancy reduction scheme based on TS (TS-R) to reduce nontrivial transmission redundancy that is generated by the trail. The theoretical and numerical analysis is provided to prove the efficiency of TS. Compared with the well-known expanding ring search (ERS), TS significantly reduces the energy consumption and search delay. PMID:29077017

  9. Low gamma counting for measuring NORM/TENORM with a radon reducing system

    2001-06-01

    A detection system for counting low levels of gamma radiation was built by upgrading an existing rectangular chamber made of 18 metric tonne of steel fabricated before World War II. The internal walls, the ceiling, and the floor of the chamber are covered with copper sheets. The new detection system consists of a stainless steel hollow cylinder with variable circular apertures in the cylindrical wall and in the base, to allow introduction of a NaI (Tl) crystal, or alternatively, a HPGe detector in its interior. This counting system is mounted inside the larger chamber, which in turn is located in a subsurface air-conditioned room. The access to the subsurface room is made from a larger entrance room through a tunnel plus a glass anteroom to decrease the air-exchange rate. Both sample and detector are housed inside the stainless steel cylinder. This cylinder is filled with hyper pure nitrogen gas, before counting a sample, to prevent radon coming into contact with the detector surface. As a consequence, the contribution of the 214Bi photopeaks to the background gamma spectra is minimized. The reduction of the gamma radiation background near the detector facilitates measurement of naturally occurring radioactive materials (NORM), and/or technologically enhanced NORM (TENORM), which are usually at concentration levels only slightly higher than those typically found in the natural radioactive background.

While several authors have analyzed the motives of these measures individually, this article provides a broader explanation for their diffusion. In empirical terms, it focuses on ‘conflict minerals’ and illegally logged timber. Building on the classical norm life cycle, the article’s argument is t...

  16. Norms as Group-Level Constructs: Investigating School-Level Teen Pregnancy Norms and Behaviors.

    Social norms are a group-level phenomenon, but past quantitative research has rarely measured them in the aggregate or considered their group-level properties. We used the school-based design of the National Longitudinal Study of Adolescent Health to measure normative climates regarding teen pregnancy across 75 U.S. high schools. We distinguished between the strength of a school's norm against teen pregnancy and the consensus around that norm. School-level norm strength and dissensus were strongly (r = -0.65) and moderately (r = 0.34) associated with pregnancy prevalence within schools, respectively. Normative climate partially accounted for observed racial differences in school pregnancy prevalence, but norms were a stronger predictor than racial composition. As hypothesized, schools with both a stronger average norm against teen pregnancy and greater consensus around the norm had the lowest pregnancy prevalence. Results highlight the importance of group-level normative processes and of considering the local school environment when designing policies to reduce teen pregnancy.

    The identification of learning mechanisms for locomotion has been the subject of much research for some time but many challenges remain. Dynamic systems theory (DST) offers a novel approach to humanoid learning through environmental interaction. Reinforcement learning (RL) has offered a promising method to adaptively link the dynamic system to the environment it interacts with via a reward-based value system. In this paper, we propose a model that integrates the above perspectives and applies it to the case of a humanoid (NAO) robot learning to walk the ability of which emerges from its value-based interaction with the environment. In the model, a simplified central pattern generator (CPG) architecture inspired by neuroscientific research and DST is integrated with an actor-critic approach to RL (cpg-actor-critic). In the cpg-actor-critic architecture, least-square-temporal-difference based learning converges to the optimal solution quickly by using natural gradient learning and balancing exploration and exploitation. Futhermore, rather than using a traditional (designer-specified) reward it uses a dynamic value function as a stability indicator that adapts to the environment. The results obtained are analyzed using a novel DST-based embodied cognition approach. Learning to walk, from this perspective, is a process of integrating levels of sensorimotor activity and value.

Desarrollan una teoría que explica las etapas y los mecanismos a través de los cuales las normas internacionales generan cambios en el comportamiento de los actores internacionales y transnacionales, y que ayuda a comprender mejor el impacto general de las normas en la política internacional. Este proceso mediante el cual las normas internacionales son interiorizadas e implementadas domésticamente puede ser entendido según los autores como un proceso de socialización. In this article Thomas Risse y Kathryn Sikkink analyze the importance of international norms impact over domestic politics and propose a five phases “spiral model” to explain the changes in human rights internalization by the states. They develop a theoretical framework that explains the stages and mechanisms by which international norms promote changes in international and transnational actors behavior, and that serves to a better comprehension of the general norms impact over international politics. The process by which international norms are internalized and implented on the domestic level can be understood, according to the authors, as a socialization process.

  5. Adaptive Actor-Critic Design-Based Integral Sliding-Mode Control for Partially Unknown Nonlinear Systems With Input Disturbances.

    Science.gov (United States)

    Fan, Quan-Yong; Yang, Guang-Hong

    2016-01-01

    This paper is concerned with the problem of integral sliding-mode control for a class of nonlinear systems with input disturbances and unknown nonlinear terms through the adaptive actor-critic (AC) control method. The main objective is to design a sliding-mode control methodology based on the adaptive dynamic programming (ADP) method, so that the closed-loop system with time-varying disturbances is stable and the nearly optimal performance of the sliding-mode dynamics can be guaranteed. In the first step, a neural network (NN)-based observer and a disturbance observer are designed to approximate the unknown nonlinear terms and estimate the input disturbances, respectively. Based on the NN approximations and disturbance estimations, the discontinuous part of the sliding-mode control is constructed to eliminate the effect of the disturbances and attain the expected equivalent sliding-mode dynamics. Then, the ADP method with AC structure is presented to learn the optimal control for the sliding-mode dynamics online. Reconstructed tuning laws are developed to guarantee the stability of the sliding-mode dynamics and the convergence of the weights of critic and actor NNs. Finally, the simulation results are presented to illustrate the effectiveness of the proposed method.

  6. Oil market structures-strategies and performances of the actors of the international petroleum system

    1999-01-01

    The rises of petroleum prices as revealed by the oil crises of the 1970's are the consequences of a beside market perverse game between artificial factors. The public management and the intervention of public authorities have contributed to the unbalancing of oil markets and to the confusion of the actor's strategies in the international petroleum system. The chronical decay of the petroleum prices indicate the slow and silent come back of the economical forces (laws). The management of an exhaustible asset like petroleum, raises lot of intriguing problems. This work aims at exploring the problems linked with this type of management where the decisions of the profession, of private and public companies and of the governments are closely interfering. The study is largely inspired of the meso-economical approach which consists in examining the markets structure and their determining factors, and the strategies and results of the actors of the world petroleum system. The examination of the structures/strategies/results sequence does not neglect the relations and feedbacks between each of these elements. The economical theory of oligopoly and cartel markets is also used to examine the way how prices are determined in petroleum markets. A critical presentation of the energy models allows to show how it is possible to understand, foresee and control the evolution of these prices and the possible supply/demand equilibrium. The study takes also into consideration the debates and controversies about the 'green tax' and its impact of petroleum supply and demand. (J.S.)

    Full Text Available Indirect reciprocity, besides providing a convenient framework to address the evolution of moral systems, offers a simple and plausible explanation for the prevalence of cooperation among unrelated individuals. By helping someone, an individual may increase her/his reputation, which may change the pre-disposition of others to help her/him in the future. This, however, depends on what is reckoned as a good or a bad action, i.e., on the adopted social norm responsible for raising or damaging a reputation. In particular, it remains an open question which social norms are able to foster cooperation in small-scale societies, while enduring the wide plethora of stochastic affects inherent to finite populations. Here we address this problem by studying the stochastic dynamics of cooperation under distinct social norms, showing that the leading norms capable of promoting cooperation depend on the community size. However, only a single norm systematically leads to the highest cooperative standards in small communities. That simple norm dictates that only whoever cooperates with good individuals, and defects against bad ones, deserves a good reputation, a pattern that proves robust to errors, mutations and variations in the intensity of selection.

    Individuals often apply social rules when they interact with computers, and this is known as the Computers Are Social Actors (CASA) effect. Following previous work, one approach to understand the mechanism responsible for CASA is to utilize computer agents and have the agents attempt to gain human compliance (e.g., completing a pattern recognition task). The current study focuses on three key factors frequently cited to influence traditional notions of compliance: evaluations toward the source (competence and warmth), normative influence (reciprocity), and affective influence (mood). Structural equation modeling assessed the effects of these factors on human compliance with computer request. The final model shows that norm-based influence (reciprocity) increased the likelihood of compliance, while evaluations toward the computer agent did not significantly influence compliance.

  12. Counterterrorism in the Russian Arctic: legal framework and central actors

    Ingvill M. Elgsaas

    2017-12-01

    Full Text Available Russia’s strategic interests in the Arctic coupled with a complex and diffuse terrorist threat has produced a niche topic: Arctic counterterrorism. Arctic counterterrorism is a new and underdeveloped topic that has received only limited attention. This article contributes a discussion of the legal framework and the main actors involved in countering terrorism in the Russian Arctic. The author finds that the legal framework for counterterrorism is extensive yet centered in core documents. Similarly, counterterrorism involves many and varied actors united in a relatively simple and streamlined national system for counterterrorism. Current legal regulation and organisation provide a solid base that may support efficient management of counterterrorism, also in the Arctic. A notable strength is the concentration of coordination responsibilities in the hands of one central actor, the FSB. Another important characteristic is that the system is symmetrical and follows Russia’s federal organisation with coordinating bodies for all regions including those in the Arctic. Counterterrorism legislation is kept up to date and the trend is towards tougher punishments and a wide understanding of terrorist offenses. A potential weak spot is the unclear role of the newly formed National Guard. The uncertainty surrounding the role of the National Guard in the fight against terrorism may challenge the FSB and weaken coordination of the system for counterterrorism in the future.

    1995-01-01

    An analysis of the participation of social and political actors in the process of formulating health policy allows one to understand the specific characteristics of the organization and operation of a health system. This study analyzes the drafting process for the General Health Act (LGS) in Spain with the purpose of establishing the relationship between social, political, and economic actors in both the formulation of the Act itself and the organization of the Spanish Health System. A case study was carried out from 1982 through 1986. Documentary parliamentary data, the medical press, national magazines and journals, and press reports by political, social, and public health actors were analyzed. The first version of the General Health Act presented by the Spanish Socialist Workers' Party (PSOE) proposed a health system with funding and public administration aimed at achieving universal health coverage, integrated care, community participation, and health education. This proposal was submitted to a complex negotiating process with business groups, unions, and health professionals. The General Health Act as finally approved excludes the principles of equity and incorporates private interests in health: "free choice of doctor and hospital", public funding and private administration of the health system, and the establishment of Social Security as the core of the entire health system.

    Full Text Available The character and quality of Latin America’s democracy is in dispute. Uncertainties about its nature and future prevail in the development debate. In the early 2000s the UNDP (2004 coined the terms “low-intensity citizenship” and “low-intensity democracy” to describe the post-dictatorship democracy in the region. When in the 1980s the military establishment withdrew from the political arena and democracy was restored, a severe economic crisis affected the region, producing long lasting effects in terms of mass poverty, informality and social exclusion. In the urban domain, and especially in territories where the representatives of law and order are relatively absent, “uncivil” nonstate actors surfaced, including local drug lords and their small territorial armies; youth gangs; organised crime and the so-called “dark forces”, joined by former belligerent actors of the Andean and Central American civil wars. In this article, I will analyse and typify this erosion of formal social order and the emergence of parallel and informal structures and hierarchies throughout Latin America.

  16. What Can We Learn About the Processes of Regulation of Tuberculosis Medicines From the Experiences of Health Policy and System Actors in India, Tanzania, and Zambia?

    Directory of Open Access Journals (Sweden)

    2016-07-01

    Full Text Available Background: The unregulated availability and irrational use of tuberculosis (TB medicines is a major issue of public health concern globally. Governments of many low- and middle-income countries (LMICs have committed to regulating the quality and availability of TB medicines, but with variable success. Regulation of TB medicines remains an intractable challenge in many settings, but the reasons for this are poorly understood. The objective of this paper is to elaborate processes of regulation of quality and availability of TB medicines in three LMICs – India, Tanzania, and Zambia – and to understand the factors that constrain and enable these processes. Methods: We adopted the action-centred approach of policy implementation analysis that draws on the experiences of relevant policy and health system actors in order to understand regulatory processes. We drew on data from three case studies commissioned by the World Health Organization (WHO, on the regulation of TB medicines in India, Tanzania, and Zambia. Qualitative research methods were used, including in-depth interviews with 89 policy and health system actors and document review. Data were organized thematically into accounts of regulators’ authority and capacity; extent of policy implementation; and efficiency, transparency, and accountability. Results: In India, findings included the absence of a comprehensive policy framework for regulation of TB medicines, constraints of authority and capacity of regulators, and poor implementation of prescribing and dispensing norms in the majority private sector. Tanzania had a policy that restricted import, prescribing and dispensing of TB medicines to government operators. Zambia procured and dispensed TB medicines mainly through government services, albeit in the absence of a single policy for restriction of medicines. Three cross-cutting factors emerged as crucially influencing regulatory processes - political and stakeholder support for

    2010-12-01

    Full Text Available Approaches to diplomacy tend to be restrictive because of an exclusively interstate insight. Indeed, historically, the state monopoly over diplomacy has always been challenged by private actors. Today, it is defied both from the inside because of growing public fragmentation (every ministry tends to lead its own foreign policy; subnational authorities develop their diplomatic relations and from the outside (the business sector and civil society play a growing role on the international scene. This proliferation of actors has transformed diplomatic methods. Beyond the binary division between “old diplomacy” – bilateral, secret and resident – and “new diplomacy” – multilateral, public and itinerant – this article shows that diplomacy has to adapt to number and complexity. Therefore a more global conception need now be considered. Diplomacy today is a system of multiple actors using diverse methods in order to coordinate positions of common interest in a competitive and sometimes hostile environment.

    This study determined if actors could portray depressed patients to establish the interrater reliability of raters using the Hamilton Depression Rating Scale (HDRS). Actors portrayed depressed patients using scripts derived from HDRS assessments obtained at three points during treatment. Four experienced raters blindly viewed videotapes of two patients and two actors. They guessed if each interviewee was a patient or an actor and rated the certainty of their guesses. For each interview, they also rated the realism of the portrayal and completed the HDRS. Experienced raters could not distinguish actors and patients better than chance and were equally certain of their right and wrong guesses. Actors and patients received high scores on the realism of their portrayals. The HDRS scores of the actor-patient pairs were correlated. Actors can effectively portray depressed patients. Future studies will determine if actors can accurately portray patients with anxiety and psychosis.

  3. Action adaptation during natural unfolding social scenes influences action recognition and inferences made about actor beliefs.

    2016-07-01

    When observing another individual's actions, we can both recognize their actions and infer their beliefs concerning the physical and social environment. The extent to which visual adaptation influences action recognition and conceptually later stages of processing involved in deriving the belief state of the actor remains unknown. To explore this we used virtual reality (life-size photorealistic actors presented in stereoscopic three dimensions) to see how visual adaptation influences the perception of individuals in naturally unfolding social scenes at increasingly higher levels of action understanding. We presented scenes in which one actor picked up boxes (of varying number and weight), after which a second actor picked up a single box. Adaptation to the first actor's behavior systematically changed perception of the second actor. Aftereffects increased with the duration of the first actor's behavior, declined exponentially over time, and were independent of view direction. Inferences about the second actor's expectation of box weight were also distorted by adaptation to the first actor. Distortions in action recognition and actor expectations did not, however, extend across different actions, indicating that adaptation is not acting at an action-independent abstract level but rather at an action-dependent level. We conclude that although adaptation influences more complex inferences about belief states of individuals, this is likely to be a result of adaptation at an earlier action recognition stage rather than adaptation operating at a higher, more abstract level in mentalizing or simulation systems.

  4. Not just the norm: exemplar-based models also predict face aftereffects.

    2014-02-01

    The face recognition literature has considered two competing accounts of how faces are represented within the visual system: Exemplar-based models assume that faces are represented via their similarity to exemplars of previously experienced faces, while norm-based models assume that faces are represented with respect to their deviation from an average face, or norm. Face identity aftereffects have been taken as compelling evidence in favor of a norm-based account over an exemplar-based account. After a relatively brief period of adaptation to an adaptor face, the perceived identity of a test face is shifted toward a face with attributes opposite to those of the adaptor, suggesting an explicit psychological representation of the norm. Surprisingly, despite near universal recognition that face identity aftereffects imply norm-based coding, there have been no published attempts to simulate the predictions of norm- and exemplar-based models in face adaptation paradigms. Here, we implemented and tested variations of norm and exemplar models. Contrary to common claims, our simulations revealed that both an exemplar-based model and a version of a two-pool norm-based model, but not a traditional norm-based model, predict face identity aftereffects following face adaptation.

  5. The moral problem of worse actors

    Directory of Open Access Journals (Sweden)

    Scott Wisor

    2014-05-01

    Full Text Available Individuals and institutions sometimes have morally stringent reasons to not do a given action. For example, an oil company might have morally stringent reasons to refrain from providing revenue to a genocidal regime, or an engineer might have morally stringent reasons to refrain from providing her expertise in the development of weapons of mass destruction. But in some cases, if the agent does not do the action, another actor will do it with much worse consequences. For example, the oil company might know their assets will be bought by a company with worse environmental and labor practices. Or the engineer might know her position will be filled by a more ambitious and amoral engineer. I call this the moral problem of worse actors (MPWA. MPWA gives reason, at least some of the time, to consider otherwise morally impermissible actions permissible or even obligatory. On my account, doing the action in the circumstances of MPWA remains morally objectionable even if permissible or obligatory, and this brings additional moral responsibilities and obligations to the actor. Similarly, not doing the action in the circumstances of MPWA may also bring additional (but different moral responsibilities and obligations. Acknowledging MPWA creates considerable challenges, as many bad actors may appeal to it to justify morally objectionable action. In this paper, I develop a set of strategies for individuals and institutions to handle MPWA. This includes appeals to integrity and the proper attribution of expressive responsibility, regulatory responsibility, and compensatory responsibility. I also address a set of related concerns, including worries about incentivizing would-be bad actors, concerns about epistemic uncertainty, and the problem of mala in se exceptions.

    Norm-based coding, in which faces are coded as deviations from an average face, is an efficient way of coding visual patterns that share a common structure and must be distinguished by subtle variations that define individuals. Adults and school-aged children use norm-based coding for face identity but it is not yet known if pre-school aged children also use norm-based coding. We reasoned that the transition to school could be critical in developing a norm-based system because school places new demands on children's face identification skills and substantially increases experience with faces. Consistent with this view, face identification performance improves steeply between ages 4 and 7. We used face identity aftereffects to test whether norm-based coding emerges between these ages. We found that 4 year-old children, like adults, showed larger face identity aftereffects for adaptors far from the average than for adaptors closer to the average, consistent with use of norm-based coding. We conclude that experience prior to age 4 is sufficient to develop a norm-based face-space and that failure to use norm-based coding cannot explain 4 year-old children's poor face identification skills.

    This paper considers the actor-critic contextual bandit for the mobile health (mHealth) intervention. The state-of-the-art decision-making methods in mHealth generally assume that the noise in the dynamic system follows the Gaussian distribution. Those methods use the least-square-based algorithm to estimate the expected reward, which is prone to the existence of outliers. To deal with the issue of outliers, we propose a novel robust actor-critic contextual bandit method for the mHealth inter...

  12. Dutch taboo norms.

    Science.gov (United States)

    Roest, Sander A; Visser, Tessa A; Zeelenberg, René

    2018-04-01

    This article provides norms for general taboo, personal taboo, insult, valence, and arousal for 672 Dutch words, including 202 taboo words. Norms were collected using a 7-point Likert scale and based on ratings by psychology students from the Erasmus University Rotterdam in The Netherlands. The sample consisted of 87 psychology students (58 females, 29 males). We obtained high reliability based on split-half analyses. Our norms show high correlations with arousal and valence ratings collected by another Dutch word-norms study (Moors et al.,, Behavior Research Methods, 45, 169-177, 2013). Our results show that the previously found quadratic relation (i.e., U-shaped pattern) between valence and arousal also holds when only taboo words are considered. Additionally, words rated high on taboo tended to be rated low on valence, but some words related to sex rated high on both taboo and valence. Words that rated high on taboo rated high on insult, again with the exception of words related to sex many of which rated low on insult. Finally, words rated high on taboo and insult rated high on arousal. The Dutch Taboo Norms (DTN) database is a useful tool for researchers interested in the effects of taboo words on cognitive processing. The data associated with this paper can be accessed via the Open Science Framework ( https://osf.io/vk782/ ).

  13. Finite-time H∞ control for linear continuous system with norm-bounded disturbance

    Science.gov (United States)

    Meng, Qingyi; Shen, Yanjun

    2009-04-01

    In this paper, the definition of finite-time H∞ control is presented. The system under consideration is subject to time-varying norm-bounded exogenous disturbance. The main aim of this paper is focused on the design a state feedback controller which ensures that the closed-loop system is finite-time bounded (FTB) and reduces the effect of the disturbance input on the controlled output to a prescribed level. A sufficient condition is presented for the solvability of this problem, which can be reduced to a feasibility problem involving linear matrix inequalities (LMIs). A detailed solving method is proposed for the restricted linear matrix inequalities. Finally, examples are given to show the validity of the methodology.

    Grondman, Ivo; Vaandrager, Maarten; Buşoniu, Lucian; Babuska, Robert; Schuitema, Erik

    2012-06-01

    We propose two new actor-critic algorithms for reinforcement learning. Both algorithms use local linear regression (LLR) to learn approximations of the functions involved. A crucial feature of the algorithms is that they also learn a process model, and this, in combination with LLR, provides an efficient policy update for faster learning. The first algorithm uses a novel model-based update rule for the actor parameters. The second algorithm does not use an explicit actor but learns a reference model which represents a desired behavior, from which desired control actions can be calculated using the inverse of the learned process model. The two novel methods and a standard actor-critic algorithm are applied to the pendulum swing-up problem, in which the novel methods achieve faster learning than the standard algorithm.

  16. A false dichotomy? Mental illness and lone-actor terrorism.

    Corner, Emily; Gill, Paul

    2015-02-01

    We test whether significant differences in mental illness exist in a matched sample of lone- and group-based terrorists. We then test whether there are distinct behavioral differences between lone-actor terrorists with and without mental illness. We then stratify our sample across a range of diagnoses and again test whether significant differences exist. We conduct a series of bivariate, multivariate, and multinomial statistical tests using a unique dataset of 119 lone-actor terrorists and a matched sample of group-based terrorists. The odds of a lone-actor terrorist having a mental illness is 13.49 times higher than the odds of a group actor having a mental illness. Lone actors who were mentally ill were 18.07 times more likely to have a spouse or partner who was involved in a wider movement than those without a history of mental illness. Those with a mental illness were more likely to have a proximate upcoming life change, more likely to have been a recent victim of prejudice, and experienced proximate and chronic stress. The results identify behaviors and traits that security agencies can utilize to monitor and prevent lone-actor terrorism events. The correlated behaviors provide an image of how risk can crystalize within the individual offender and that our understanding of lone-actor terrorism should be multivariate in nature.

  17. Using attractiveness model for actors ranking in social media networks.

    Science.gov (United States)

    Qasem, Ziyaad; Jansen, Marc; Hecking, Tobias; Hoppe, H Ulrich

    2017-01-01

    Influential actors detection in social media such as Twitter or Facebook can play a major role in gathering opinions on particular topics, improving the marketing efficiency, predicting the trends, etc. This work aims to extend our formally defined T measure to present a new measure aiming to recognize the actor's influence by the strength of attracting new important actors into a networked community. Therefore, we propose a model of the actor's influence based on the attractiveness of the actor in relation to the number of other attractors with whom he/she has established connections over time. Using an empirically collected social network for the underlying graph, we have applied the above-mentioned measure of influence in order to determine optimal seeds in a simulation of influence maximization. We study our extended measure in the context of information diffusion because this measure is based on a model of actors who attract others to be active members in a community. This corresponds to the idea of the IC simulation model which is used to identify the most important spreaders in a set of actors.

  18. What's in a norm? Sources and processes of norm change.

    2009-03-01

    This reply to the commentary by E. Staub and L. A. Pearlman (2009) revisits the field experimental results of E. L. Paluck (2009). It introduces further evidence and theoretical elaboration supporting Paluck's conclusion that exposure to a reconciliation-themed radio soap opera changed perceptions of social norms and behaviors, not beliefs. Experimental and longitudinal survey evidence reinforces the finding that the radio program affected socially shared perceptions of typical or prescribed behavior-that is, social norms. Specifically, measurements of perceptions of social norms called into question by Staub and Pearlman are shown to correlate with perceptions of public opinion and public, not private, behaviors. Although measurement issues and the mechanisms of the radio program's influence merit further testing, theory and evidence point to social interactions and emotional engagement, not individual education, as the likely mechanisms of change. The present exchange makes salient what is at stake in this debate: a model of change based on learning and personal beliefs versus a model based on group influence and social norms. These theoretical models recommend very different strategies for prejudice and conflict reduction. Future field experiments should attempt to adjudicate between these models by testing relevant policies in real-world settings.

  1. Economical modelling of social and moral norms

    International Nuclear Information System (INIS)

    Nyborg, Karine

    2001-01-01

    Social norms and moral motivations are often ignored in economic models. It is possible, however, to model social and moral norms within the framework of economical theory. This may be useful even if the exposition is necessarily simplified. The article gives some examples. An analysis shows how the ''No Smoking Act'' may have led to a change in social norms in Norway and indirectly changed the behaviour of smokers in places where this act does not apply. Behaviour with moral motivation may also be affected by changes in regulations, economic incentives or other external conditions. For example, a more efficient collection system for source-separated waste may induce people to sharpen the moral claim on their own efforts. Indeed, interviews show that imposing a fee upon people not volunteering in communal work may cause the attendance to drop further

    The Millennium Development Goals have ended and the Sustainable Development Goals have begun, marking a shift in the global health landscape. The frame of reference has changed from a focus on 8 development priorities to an expansive set of 17 interrelated goals intended to improve the well-being of all people. In this time of change, several groups, including the Lancet Commission on Global Surgery, have brought a critical problem to the fore: 5 billion people lack access to safe, affordable surgical and anaesthesia care when needed. The magnitude of this problem and the world's new focus on strengthening health systems mandate reimagined roles for and renewed commitments from high income country actors in global surgery. To discuss the way forward, on 6 May 2015, the Commission held its North American launch event in Boston, Massachusetts. Panels of experts outlined the current state of knowledge and agreed on the roles of surgical colleges and academic medical centres; trainees and training programmes; academia; global health funders; the biomedical devices industry, and news media and advocacy organisations in building sustainable, resilient surgical systems. This paper summarises these discussions and serves as a consensus statement providing practical advice to these groups. It traces a common policy agenda between major actors and provides a roadmap for maximising benefit to surgical patients worldwide. To close the access gap by 2030, individuals and organisations must work collectively, interprofessionally and globally. High income country actors must abandon colonial narratives and work alongside low and middle income country partners to build the surgical systems of the future. PMID:28588908

  4. Recollection and unitization in associating actors with extrinsic and intrinsic motions.

    Kersten, Alan W; Earles, Julie L; Berger, Johanna D

    2015-04-01

    Four experiments provide evidence for a distinction between 2 different kinds of motion representations. Extrinsic motions involve the path of an object with respect to an external frame of reference. Intrinsic motions involve the relative motions of the parts of an object. This research suggests that intrinsic motions are represented conjointly with information about the identities of the actors who perform them, whereas extrinsic motions are represented separately from identity information. Experiment 1 demonstrated that participants remembered which actor had performed a particular intrinsic motion better than they remembered which actor had performed a particular extrinsic motion. Experiment 2 replicated this effect with incidental encoding of actor information, suggesting that encoding intrinsic motions leads one to automatically encode identity information. The results of Experiments 3 and 4 were fit by Yonelinas's (1999) source-memory model to quantify the contributions of familiarity and recollection to memory for the actors who carried out the intrinsic and extrinsic motions. Successful performance with extrinsic motion items in Experiment 3 required participants to remember in which scene contexts an actor had appeared, whereas successful performance in Experiment 4 required participants to remember the exact path taken by an actor in each scene. In both experiments, discrimination of old and new combinations of actors and extrinsic motions relied strongly on recollection, suggesting independent but associated representations of actors and extrinsic motions. In contrast, participants discriminated old and new combinations of actors and intrinsic motions primarily on the basis of familiarity, suggesting unitized representations of actors and intrinsic motions.

  6. The Grand Strategy of Nonstate Actors: Theory and Implications

    Directory of Open Access Journals (Sweden)

    Garrett Pierman

    2015-12-01

    Full Text Available This article addresses the Realist assumption that only actors that are states can be considered to have a strategic culture. The primary issue raised is the question of the ability of non-state actors to have a strategic culture. Al-Qaida is used as a theoretical case study. Ultimately this article rejects the idea of territoriality in strategic culture formulation and calls for academics and policymakers alike to adopt a broader conception of actors on the international, stage. This broader conception of actors would necessitate rich case studies to be done in the future in order to seek an understanding of the strategic culture of the non-state actors which academics and policymakers must deal with in the modern security environment. In particular, the article finds that the assumptions held about al-Qaida thus far are wrong and, in reality, the group has ambitions that are cosmic in nature, which will necessitate change in the strategies used to fight against terrorism.

  7. The key role of supply chain actors in groundwater irrigation development in North Africa

    2017-09-01

    The role played by supply chain actors in the rapid development of groundwater-based irrigated agriculture is analyzed. Agricultural groundwater use has increased tremendously in the past 50 years, leading to the decline of water tables. Groundwater use has enabled intensification of existing farming systems and ensured economic growth. This "groundwater economy" has been growing rapidly due to the initiative of farmers and the involvement of a wide range of supply chain actors, including suppliers of equipment, inputs retailers, and distributors of irrigated agricultural products. In North Africa, the actors in irrigated production chains often operate at the margin of public policies and are usually described as "informal", "unstructured", and as participating in "groundwater anarchy". This paper underlines the crucial role of supply chain actors in the development of groundwater irrigation, a role largely ignored by public policies and rarely studied. The analysis is based on three case studies in Morocco, Tunisia and Algeria, and focuses on the horticultural sub-sector, in particular on onions and tomatoes, which are irrigated high value crops. The study demonstrates that although supply chain actors are catalyzers of the expansion of groundwater irrigation, they could also become actors in adaptation to the declining water tables. Through their informal activities, they help reduce market risks, facilitate credit and access to subsidies, and disseminate innovation. The interest associated with making these actors visible to agricultural institutions is discussed, along with methods of getting them involved in the management of the resource on which they depend.

  8. Children are sensitive to norms of giving.

    2017-10-01

    People across societies engage in costly sharing, but the extent of such sharing shows striking cultural variation, highlighting the importance of local norms in shaping generosity. Despite this acknowledged role for norms, it is unclear when they begin to exert their influence in development. Here we use a Dictator Game to investigate the extent to which 4- to 9-year-old children are sensitive to selfish (give 20%) and generous (give 80%) norms. Additionally, we varied whether children were told how much other children give (descriptive norm) or what they should give according to an adult (injunctive norm). Results showed that children generally gave more when they were exposed to a generous norm. However, patterns of compliance varied with age. Younger children were more likely to comply with the selfish norm, suggesting a licensing effect. By contrast, older children were more influenced by the generous norm, yet capped their donations at 50%, perhaps adhering to a pre-existing norm of equality. Children were not differentially influenced by descriptive or injunctive norms, suggesting a primacy of norm content over norm format. Together, our findings indicate that while generosity is malleable in children, normative information does not completely override pre-existing biases. Copyright © 2017 Elsevier B.V.

    Achourioti, Theodora; Fugard, Andrew J. B.; Stenning, Keith

    2014-01-01

    This paper argues that the goals people have when reasoning determine their own norms of reasoning. A radical descriptivism which avoids norms never worked for any science; nor can it work for the psychology of reasoning. Norms as we understand them are illustrated with examples from categorical syllogistic reasoning and the “new paradigm” of subjective probabilities. We argue that many formal systems are required for psychology: classical logic, non-monotonic logics, probability logics, relevance logic, and others. One of the hardest challenges is working out what goals reasoners have and choosing and tailoring the appropriate logics to model the norms those goals imply. PMID:25368590

  10. Change-actors in the U.S. electric energy system: The role of environmental groups in utility adoption and diffusion of wind power

    International Nuclear Information System (INIS)

    Doblinger, Claudia; Soppe, Birthe

    2013-01-01

    We study the contribution of environmental groups to new technology adoption and diffusion by dominant incumbents. Building on institutional and social movement theory, we develop a theoretical framework that sheds light on environmental groups as change-actors. We theorize that by approaching embedded key constituents with various strategic actions, environmental groups affect taken-for-granted beliefs, build legitimacy for renewable energy technologies, and convince skeptical constituents to support the new technology. We verify our theoretical framework with a case study of wind power development in Colorado. We find that environmentalists educate constituents on the benefits of the new technology, engage in activities leading to regulatory and legislative decisions for wind, while also providing direct assistance to the utility. As a result, utilities are both pressured and encouraged to adopt and diffuse wind power on a large-scale. This research directs attention to the role of environmental groups as change-actors and the legitimating effects of their actions. It highlights their part in creating a more favorable institutional environment for new technologies while directly influencing the incumbent's technology choice. This paper contributes to an understanding of bottom-up, actor-initiated changes in energy systems taking into account both the systemic technological infrastructure and the institutional context. - Highlights: • We study environmentalists′ impact on utility-scale renewable technology diffusion. • Incumbent-dominated systems hinder the diffusion of new technologies. • Environmental groups′ strategic actions increase legitimacy for new technologies. • Environmental groups′ legitimating actions affect incumbent′s technology choice. • Environmental groups create a favorable institutional context for new technologies

    The isolation of radioactive waste from the environment becomes a real problem need to solve in the last half century. Waste management system is created for safe isolation of the waste. Radioactive waste management including all activities, administrative and operational, That are involved in the handling, conditioning, transport, storage and disposal of radioactive wastes. In petroleum and gas industries there are many wastes containing natural occurring radioactive waste (NORM). The concentration of NORM is increased during the different processes. Accumulation of NORM in these areas makes hazard effects on the workers and on the environment. In Egypt, there are many oil and gas industries in different areas of the republic. Most of these exploration sites containing large amounts of NORM waste. The management of this waste is remained unclear for many companies. Some companies have storage designs for the waste. Others are stored the waste on the working site on land without barriers. Additionally final destination of these wastes is not decided. The improper management of this waste lead to hazard effects to workers in the present time and to public in the future. The present work studies the NORM waste management, from petroleum industry, in Egypt. Strategy of NORM is proposed. NORM waste management steps (system) is also proposed, Incineration and deoiling processes for the treatment of NORM waste are compered. Also in this study, human intrusion scenarios were studied for two NORM storage designs, A) above-ground and B) under-ground bunkers

    2012-07-01

    Due to its environmental impact, the mobility system is increasingly under pressure. The challenges to cope with climate change, air quality, depleting fossil resources imply the need for a transition of the current mobility system towards a more sustainable one. Expectations and visions have been identified as crucial in the guidance of such transitions, and more specifically of actor strategies. Still, it remained unclear why the actors involved in transition activities appear to change their strategies frequently and suddenly. The empirical analysis of the expectations and strategies of three actors in the field of hydrogen and fuel cell technology indicates that changing actor strategies can be explained by rather volatile expectations related to different levels. Our case studies of the strategies of two large car manufacturers and the German government demonstrate that the car manufacturers refer strongly to expectations about the future regime, while expectations related to the socio-technical landscape level appear to be crucial for the strategy of the German government.

    There are a number of industries generating NORM wastes in Malaysia. These include oil and gas and minerals/ores processing industries. A safe management of radioactive wastes is required. The existing guidelines are insufficient to help the management of oil and gas wastes. More guidelines are required to deal with NORM wastes from minerals/ores processing industries. To ensure that radioactive wastes are safely managed and disposed of, a National Policy on the Safe Management of Radioactive Waste is being developed which also include NORM waste. This paper describes the current status of NORM waste management in Malaysia. (author)

  15. Optimal Placement of Actors in WSANs Based on Imposed Delay Constraints

    Directory of Open Access Journals (Sweden)

    Chunxi Yang

    2014-01-01

    Full Text Available Wireless Sensor and Actor Networks (WSANs refer to a group of sensors and actors linked by wireless medium to probe environment and perform specific actions. Such certain actions should always be taken before a deadline when an event of interest is detected. In order to provide such services, the whole monitor area is divided into several virtual areas and nodes in the same area form a cluster. Clustering of the WSANs is often pursued to give that each actor acts as a cluster-head. The number of actors is related to the size and the deployment of WSANs cluster. In this paper, we find a method to determine the accurate number of actors which enables them to receive data and take actions in an imposed time-delay. The k-MinTE and the k-MaxTE clustering algorithm are proposed to form the minimum and maximum size of cluster, respectively. In those clustering algorithms, actors are deployed in such a way that sensors could route data to actors within k hops. Then, clusters are arranged by the regular hexagon. At last, we evaluate the placement of actors and results show that our approach is effective.

In order to circumvent this issue, we define a three level semantics giving independent definitions of the functionality of actors, the temporal properties...... of communications, and finally imposing deadlines on the timing of dependent actors. With this approach the semantics is used directly in developing a simulator supporting the nondeterminism of the abstract semantics such that e.g. potential race conditions can be detected.

The verification task for timed, hybrid systems can thus be divided into the continuous, discrete, and timing domains with automated translation to specialized tools, and this promises better scalability than simulation or model checking of one complex model....

    Different studies regarding the role of norms on the expression of prejudice have shown that the anti-prejudice norm influences people to inhibit prejudice expressions. However, if norm pressure has led to a substantial decrease in the public expression of prejudice against certain targets (e.g., blacks, women, blind people), little theoretical and empirical attention has been paid to the role of this general norm regarding sexual minorities (e.g., prostitutes, lesbians and gays). In this sense, the issue we want to address is whether general anti-prejudice norms can reduce the expression of prejudice against homosexual individuals. In this research we investigate the effect of activating an anti-prejudice norm against homosexuals on blatant and subtle expressions of prejudice. The anti-prejudice norm was experimentally manipulated and its effects were observed on rejection to intimacy (blatant prejudice) and on positive-negative emotions (subtle prejudice) regarding homosexuals. 136 university students were randomly allocated to activated-norm and control conditions and completed a questionnaire that included norm manipulation and the dependent variables. A multivariate analysis of variance (MANOVA) as well as subsequent ANOVAS showed that only in the high normative pressure condition participants expressed less rejection to intimacy and less negative emotions against homosexuals, when compared to the simple norm-activation and the control conditions. Positive emotions, however, were similar both in the high normative pressure and the control conditions. We concluded that a high anti-prejudice pressure regarding homosexuals could reduce blatant prejudice but not subtle prejudice, considering that the expression of negative emotions decreased while the expression of positive emotions remained stable.

Methods dialectic approach to the cognition of social phenomena allowing to analyze them in their historical development and functioning in the context of the integrity of subjective and objective factors this determines the choice of the research methods systemicstructural formallegal and comparative. Results The first part of this chapter will explain the way in which people in societies different from our own were subject to other motivations in situations where selfinterest would tend to dominate in our society. The reasoning is based on three examples one drawn from the history of Ancient Rome one from the High Middle Ages of the European society and one from a contemporary nonWestern culture. The second part of the chapter analyzes the reason why material selfinterest maximizing became a dominant motivation in the modern Western society. The works on historical sociology attribute this development to Calvinism but this hypothesis suffers from some serious defects. In the article we prove that the modern sensibility resulted from much longeracting trends specifically secularization urbanization and commercialization. The final section of the chapter explores the relationship between the Westrsquos prevailing norm of selfinterest maximization and the particular norms that have been discussed in microeconomic theory. It argues that some of these norms are internal to the prevailing one and are thus explicable in terms of material selfinterest but that others reflect additional norms in the general society that exist alongside and sometimes in competition with the prevailing norm of selfinterest maximization. The historicallybased view that selfinterest maximizing is a prevailing norm rather than a human universal allows these other norms to be acknowledged in a plausible and realistic manner rather than being explained away by a

    To directly use a virtual surface model for action editing and movement control, a general method for creating virtual actor skeleton models and controlling movement is presented. The method includes judging borderlines of the block virtual surface model, calculat-ing the joints, confirming the above block, and using the block hierarchical layout to create the skeleton model. Then, according to the virtual actor model and move-ment restriction, the study focuses on the generation of movement animation using the key frame technique and smoothing movement technique by automatically adding animation and adjusting the actor's pose by different weights on movement amplitude. Finally, movement control of the actor in the virtual environment is implemented by real-time control and path point control, which achieve a good result.

    2008-11-06

    Auditing large, rapidly evolving terminological systems is still a challenge. In the case of RxNorm, a standardized nomenclature for clinical drugs, we argue that quality assurance processes can benefit from the recently released application programming interface (API) provided by RxNav. We demonstrate the usefulness of the API by performing a systematic comparison of alternative paths in the RxNorm graph, over several thousands of drug entities. This study revealed potential errors in RxNorm, currently under review. The results also prompted us to modify the implementation of RxNav to navigate the RxNorm graph more accurately. The RxNav web services API used in this experiment is robust and fast.

    Full Text Available We study quantum integrable models solvable by the nested algebraic Bethe ansatz and possessing gl(m|n-invariant R-matrix. We compute the norm of the Hamiltonian eigenstates. Using the notion of a generalized model we show that the square of the norm obeys a number of properties that uniquely fix it. We also show that a Jacobian of the system of Bethe equations obeys the same properties. In this way we prove a generalized Gaudin hypothesis for the norm of the Hamiltonian eigenstates.

  9. Age norms, family relationships, and home leaving in Italy

    Directory of Open Access Journals (Sweden)

    Marco Tosi

    2017-01-01

    Full Text Available Background: Previous research has shown that social norms have an influence on young adults' life course transitions. However, few studies have explicitly and directly tested the idea that perceived age norms affect the decision to leave the parental home. Objective: I ask whether normative factors are correlated with the decision to leave the family nest in Italy, and whether this association depends on a system of perceived costs and benefits, parental approval of their children's decisions, and the quality of parent-child relationships. Methods: Using the panel component of Family and Social Subjects data (2003 and 2007, logit and multinomial logit models were adopted to analyze the connection between perceived norms and behavior. The Karlson, Holm, and Breen (2012 decomposition method was used to test the relevance of confounding and mediating factors. Results: The findings show that young adults who consider themselves as too young to leave the parental home are less likely to move out of the family nest in order to marry. The interaction between a 'stay' norm, the perceived benefits of leaving home, and parental approval significantly affects the transition to independence. Contribution: In Italy, decision-making about leaving home and getting married is shaped by age norms concerning extended coresidence. Young adults tend to comply with age norms when they perceive that their decision implies benefits and/or a violation will lead to penalties. Perceived parental disapproval reduces the influence of normative factors on individual actual behaviors, which suggests that young adults adhere to norms that are supported by parents.

  11. Negative-norm states, superselection rules, and the lepton family

    International Nuclear Information System (INIS)

    Crawford, J.P.; Barut, A.O.

    1983-01-01

    Field theories containing states of both positive and negative norm are considered. With the correct definition of the number operators for the quantum fields, all physical quantities are rendered canonically normalized. If the theory admits a global symmetry leading to a superselection rule which forbids transitions between positive- and negative-norm states, then the negative-norm states are allowed to be physical. Specifically, a spinor theory with higher-order field equations and multiple excitations is considered and applied to the charged lepton system: e,μ,tau. In this model, the negative norm of the muon state allows us to understand the nonexistence of μ→eγ decay. For minimal coupling, the theory is renormalizable and equivalent to three separate fermion electrodynamics with the additional prediction of equal charge for the leptons. A further anomalous magnetic moment coupling can only allow one of the decays tau→μγ or tau→eγ

    Full Text Available Nothing in the Uruguay Round mentions directly about rights of private economic actors. It seems that the relationship to private economic actors (or may be individual does not exist within the WTO Agreements, because as a general rule, private parties are not legal subjects of the international legal order. However, this article will prevail upon this situation, by looking closer at the essence of the WTO Agreements to discern the rights of private economic actors that derive from the WTO. The main question of this article is to what extent then Indonesia is dealing with the rights of private economic actors under the WTO Agreements? The background of this questionis because four years after ratifying the WTO Agreements, Indonesia has been facing what is arguably the most serious multidimensional crisis in 1997, some difficult situations have arisen from the crisis; therefore, the society hesitated to accept the open world trading system. The society seemed look askance to the implementation of the WTO Agreements. But Indonesian Government took major step to reduce the skepticism of society toward liberalization, by readjusting its national laws conform to the WTO Agreements with the intention to support the rights of national economic actors under the WTO Agreements in order to achieve total benefits of the WTO rules.

    2017-09-01

    This paper mainly focuses on the problem of fault estimation for a class of Takagi-Sugeno fuzzy systems with state delays. A minimum norm least squares solution (MNLSS) approach is first introduced to establish a fault estimation compensator, which is able to optimize the fault estimator. Compared with most of the existing fault estimation methods, the MNLSS-based fault estimation method can effectively decrease the effect of state errors on the accuracy of fault estimation. Finally, three examples are given to illustrate the effectiveness and merits of the proposed method.

    This study examined the relationship between traditional masculine role norms (status, toughness, anti-femininity) and psychosocial mechanisms of sexual risk (sexual communication, sexual self-efficacy) among young, low-income, and minority parenting couples. Between 2007 and 2011, 296 pregnant adolescent females and their male partners were recruited from urban obstetrics clinics in Connecticut. Data regarding participants' beliefs in masculine role norms, frequency of general sex communication and sexual risk communication, and sexual self-efficacy were collected via computer-assisted self-interviews. Generalized estimating equation (GEE) models were used to test for actor effects (whether a person's masculine role norms at baseline influence the person's own psychosocial variables at 6-month follow-up) and partner effects (whether a partner's masculine role norms at baseline influence an actor's psychosocial variables at 6-month follow-up). Results revealed that higher actor status norms were significantly associated with more sexual self-efficacy, higher actor toughness norms were associated with less sexual self-efficacy, and higher actor anti-femininity norms were significantly associated with less general sex communication, sexual risk communication, and sexual self-efficacy. No partner effects were found. These results indicate a need for redefining masculine role norms through family centered approaches in pregnant or parenting adolescent couples to increase sexual communication and sexual self-efficacy. Further research is needed to understand partner effects in the context of a relationship and on subsequent sexual risk behavior. © Society for Community Research and Action 2016.

    This article analyzes the sociodemographic network characteristics and antecedent behaviors of 119 lone-actor terrorists. This marks a departure from existing analyses by largely focusing upon behavioral aspects of each offender. This article also examines whether lone-actor terrorists differ based on their ideologies or network connectivity. The analysis leads to seven conclusions. There was no uniform profile identified. In the time leading up to most lone-actor terrorist events, other people generally knew about the offender's grievance, extremist ideology, views, and/or intent to engage in violence. A wide range of activities and experiences preceded lone actors' plots or events. Many but not all lone-actor terrorists were socially isolated. Lone-actor terrorists regularly engaged in a detectable and observable range of activities with a wider pressure group, social movement, or terrorist organization. Lone-actor terrorist events were rarely sudden and impulsive. There were distinguishable behavioral differences between subgroups. The implications for policy conclude this article. © 2013 American Academy of Forensic Sciences.

  7. NORM regulations

    Energy Technology Data Exchange (ETDEWEB)

    Gray, P. [ed.

    1997-02-01

    The author reviews the question of regulation for naturally occuring radioactive material (NORM), and the factors that have made this a more prominent concern today. Past practices have been very relaxed, and have often involved very poor records, the involvment of contractors, and the disposition of contaminated equipment back into commercial service. The rationale behind the establishment of regulations is to provide worker protection, to exempt low risk materials, to aid in scrap recycling, to provide direction for remediation and to examine disposal options. The author reviews existing regulations at federal and state levels, impending legislation, and touches on the issue of site remediation and potential liabilities affecting the release of sites contaminated by NORM.

    1995-01-01

    Oil and gas field wastes and sites contaminated with naturally occurring radioactive materials (NORM) have quickly become a focus of substantial attention by regulators both at the state and federal level. Although currently regulated in a number of states, the Environmental Protection Agency (EPA) has indicated a desire to develop federal regulations to address management and disposal of NORM-contaminated wastes. This paper provides a brief overview of current state NORM regulations, currently available technologies for managing and disposing NORM wastes, and the cost of employing these techniques. Based on these characterizations and alternative assumptions about the volume of NORM wastes, four alternative scenarios have been developed to bracket potential future NORM requirements. These scenarios have been used is the basis for an analysis of the potential economic and supply impacts of NORM requirements on the U.S. oil and gas industry. The results illustrate that a reasonable approach to regulation that focuses only on those NORM wastes that pose a risk and allows producers to use safe, low cost disposal methods (downhole or other) would have minimal economic impacts on the oil and gas industry. A very stringent regulatory approach that covered large volumes of wastes, required the use of higher cost disposal techniques, and required extensive site clean-up activities could have a substantial economic impact, resulting in a loss of up to 20 percent of U.S. oil production and 8 percent of U.S. gas production by 2000. The costs of compliance with these alternative approaches could range from $71 million to over $14 billion annually. Between these two cases lies the opportunity for regulators to develop requirements for management and disposal of NORM wastes that will address any environmental and human health risks posed at industry sites without imposing unnecessarily costly regulations on the U.S. oil and gas E ampersand P industry

  10. Postdecisional counterfactual thinking by actors and readers.

    2007-06-01

    How do individuals think counterfactually about the outcomes of their decisions? Most previous studies have investigated how readers think about fictional stories, rather than how actors think about events they have actually experienced. We assumed that differences in individuals' roles (actor vs. reader) can make different information available, which in turn can affect counterfactual thinking. Hence, we predicted an effect of role on postdecisional counterfactual thinking. Reporting the results of eight studies, we show that readers undo the negative outcome of a story by undoing the protagonist's choice to tackle a given problem, rather than the protagonist's unsuccessful attempt to solve it. But actors who make the same choice and experience the same negative outcome as the protagonist undo this outcome by altering features of the problem. We also show that this effect does not depend on motivational factors. These results contradict current accounts of counterfactual thinking and demonstrate the necessity of investigating the counterfactual thoughts of individuals in varied roles.

    We investigate the square-norm distance correlation dynamics of the Bell-diagonal states under different local decoherence channels, including phase flip, bit flip, and bit-phase flip channels by employing the geometric discord (GD) and its modified geometric discord (MGD), as the measures of the square-norm distance correlations. Moreover, an explicit comparison between them is made in detail. The results show that there is no distinct dominant relative ordering between them. Furthermore, we obtain that the GD just gradually deceases to zero, while MGD initially has a large freezing interval, and then suddenly changes in evolution. The longer the freezing interval, the less the MGD is. Interestingly, it is shown that the dynamic behaviors of the two geometric discords under the three noisy environments for the Werner-type initial states are the same. (general)

    Full Text Available At first glance, the compatibility of social theory and resilience thinking is not entirely evident, in part because the ontology of the former is rooted in social interactions among human beings rather than ecological process. Despite this difference, resilience thinking engages with particular aspects of social organization that have generated intense debates within social science, namely the role of humans as integral elements of social-ecological systems and the processes through which given social structures (including material relations are either maintained or transformed. Among social theoretical approaches, Actor-Network Theory (ANT is noted for its distinctive approach to these aspects. ANT proposes that human and nonhuman components (both referred to as actants have the same capacity to influence the development of social-ecological systems (represented as actor-networks by enacting relations and enrolling other actors. We explore the notion of agency that is employed in resilience thinking and ANT in order to extend our understandings of human-environment relationships through complementary insights from each approach. The discussion is illustrated by reference to ongoing assessment of resilience as it is experienced and expressed in two distinctive agricultural production systems: Indonesian rice and New Zealand kiwifruit. We conclude by establishing the potential for ANT to provide more profound theoretical conceptualizations of agency, both human and nonhuman, in analyses of social ecological systems.

The revised taxonomy has content, discriminant, predictive, and nomological validity and satisfactory test-retest reliability. The most internalized of the new norm constructs, integrated norms, is most strongly correlated with conventional...... measures of personal and moral norms. However, other constructs in the proposed taxonomy still contribute significantly to predicting conventional norm measures after controlling for integrated norms. This documents the motivational ambiguity of the conventional personal norm construct. The patterns...

  14. Energizing and de-motivating effects of norm-conflict.

    Norms have a pervasive influence on behavior, yet previous research has not addressed that people often face conflicting norms from multiple ingroups. The current research addresses this gap in the context of proenvironmental behavior and demonstrates two effects predicted by the novel theoretical position we offer: People can be de-motivated by norm-conflict, or conversely, norm-conflict can encourage people to take action. Studies 1 and 2 demonstrated that norm-conflict is associated with increased perceived effectiveness for those with positive attitudes to the issue and reduced perceived effectiveness for those with moderate attitudes, and effectiveness perceptions mediated an indirect effect on behavioral intentions. Study 3 found that perceived effectiveness also moderates the effects of norm-conflict such that norm-conflict only influences intentions when perceived effectiveness is high. Norm-conflict is both positively and negatively related to behavioral decision making, suggesting additional considerations in the design of social norms-based interventions.

  15. NORM management in the oil and gas industry

    It has been established that Naturally Occurring Radioactive Materials (NORM) may accumulate at various locations along the oil/gas production process. Components such as wellheads, separation vessels, pumps, and other processing equipment can become NORM contaminated, and NORM can accumulate in the form of sludge, scale, scrapings and other waste media. This can create a potential radiation hazard to workers, general public and the environment if certain controls are not established. Saudi Aramco has developed NORM management guidelines and is implementing a comprehensive strategy to address all aspects of NORM management which aim towards enhancing: NORM monitoring; Control of NORM contaminated equipment; Control over NORM waste handling and disposal; Workers protection, awareness, and training. The benefits of shared knowledge, best practice and, experience across the oil and gas industry are seen as key to the establishment of common guidance. This paper outlines Saudi Aramco's experience in the development of a NORM management strategy and its goals of establishing common guidance throughout the oil and gas industry. (author)

    Full Text Available Article considers theoretical aspects of soft power concept and its use by various actors in Central Asia. It is noted that scholars as well as practitioners are paying insufficient attention to such key concepts position J. Nye, as an attraction. As a result the efficiency of the use of soft power is significantly reduced. It also shows that the attractiveness is not a universal characteristic. For this reason, attractiveness and hence soft power of different actors are different and aimed at different segments of the population. These differences lead to competition of actors, but they do not reduce interaction in the region to zero-sum game. Specific forms and directions of the soft power of Russia, the U.S., the EU and China in Central Asia are discussed. The article emphasizes that the Central Asian states are not just recipients of soft power of external actors, but also themselves form behavioral strategies that are attractive to others.

  17. Scientists in a Changed Institutional Environment: Subjective Adaptation and Social Responsibility Norms in Russia

    Energy Technology Data Exchange (ETDEWEB)

    2008-06-05

    How do scientists react when the institutional setting in which they conduct their work changes radically? How do long-standing norms regarding the social responsibility of scientists fare? What factors influence whether scientists embrace or reject the new institutions and norms? We examine these questions using data from a unique survey of 602 scientists in Russia, whose science system experienced a sustained crisis and sweeping changes in science institutions following the collapse of the Soviet Union. We develop measures of how respondents view financing based on grants and other institutional changes in the Russian science system, as well as measures of two norms regarding scientists social responsibility. We find that the majority of scientists have adapted, in the sense that they hold positive views of the new institutions, but a diversity of orientations remains. Social responsibility norms are common among Russian scientists, but far from universal. The main correlates of adaptation are age and current success at negotiating the new institutions, though prospective success, work context, and ethnicity have some of the hypothesized associations. As for social responsibility norms, the main source of variation is age: younger scientists are more likely to embrace individualistic rather than socially-oriented norms.

    2013-10-01

    Full Text Available The aim of this article is to analyze the performance of the two main trade unions (UGT and CCOO and the employers’ association CEOE during the economic crisis. The analysis focuses on their position on major reforms, on their ideological differences over various public policies, as well as on their ability to negotiate collective bargaining agreements. We depart from the command of the Spanish Constitution of 1978, which in its seventh article gives trade unions and business associations a prominent role in representing economic interests, to suggest that social actors would be likely to reduce their chances of veto in times of economic crisis given the exceptional situation. However, the article confirms a gap in the approaches of social actors and the few options for a strong social dialogue. This leads to a greater distance between the social actors and the public opinion, as evidenced by the results derived from the survey on ‘Culture and Political Representation in Spain’.

  19. Balancing influence between actors in healthcare decision making

    2011-04-01

    Full Text Available Abstract Background Healthcare costs in most developed countries are not clearly linked to better patient and public health outcomes, but are rather associated with service delivery orientation. In the U.S. this has resulted in large variation in healthcare availability and use, increased cost, reduced employer participation in health insurance programs, and reduced overall population health outcomes. Recent U.S. healthcare reform legislation addresses only some of these issues. Other countries face similar healthcare issues. Discussion A major goal of healthcare is to enhance patient health outcomes. This objective is not realized in many countries because incentives and structures are currently not aligned for maximizing population health. The misalignment occurs because of the competing interests between "actors" in healthcare. In a simplified model these are individuals motivated to enhance their own health; enterprises (including a mix of nonprofit, for profit and government providers, payers, and suppliers, etc. motivated by profit, political, organizational and other forces; and government which often acts in the conflicting roles of a healthcare payer and provider in addition to its role as the representative and protector of the people. An imbalance exists between the actors, due to the resources and information control of the enterprise and government actors relative to the individual and the public. Failure to use effective preventive interventions is perhaps the best example of the misalignment of incentives. We consider the current Pareto efficient balance between the actors in relation to the Pareto frontier, and show that a significant change in the healthcare market requires major changes in the utilities of the enterprise and government actors. Summary A variety of actions are necessary for maximizing population health within the constraints of available resources and the current balance between the actors. These actions include

    Full Text Available This paper considers the possibility of a robust and general formulation of a model of choice for the representation of a variety of moral norms. It starts by reviewing several recent models of deontological (or rule-based norms that retain the basic elements of the economic model of choice. It briefly examines the achievements and drawbacks of each model, and while no model is identified as the most accurate or robust, the most appealing aspects of each model contribute to the construction of a tout-ensemble utility function proposed in the final section. This representation of preferences aims to incorporate the most common qualities of both consequentialist and deontological moral norms in order to represent decision making under their influence.

  9. Understanding Health Information Seeking from an Actor-Centric Perspective

    Directory of Open Access Journals (Sweden)

    Simon Batchelor

    2015-07-01

    Full Text Available This paper presents a conceptual approach for discussing health information seeking among poor households in Africa and Asia. This approach is part of a larger research endeavor aimed at understanding how health systems are adapting; with possibilities and constraints emerging. These health systems can be found in a context of the changing relationships between states, markets and civil society in low and middle income countries. The paper starts from an understanding of the health sector as a “health knowledge economy”, organized to provide people with access to knowledge and advice. The use of the term “health knowledge economy” draws attention to the ways the health sector is part of a broader knowledge economy changing the way individuals and households obtain and use specialist information. The paper integrates an actor centric approach with the theory of planned behavior. It seeks to identify the actors engaged in the health knowledge economy as a precursor to longer term studies on the uptake of innovations integrating health services with mobile phones, commonly designated as mHealth, contributing to an understanding of the potential vulnerabilities of poor people, and highlighting possible dangers if providers of health information and advice are strongly influenced by interest groups.

  10. Metropolises in emerging countries: actors in energy transitions? Lessons from Cape Town (South Africa)

    International Nuclear Information System (INIS)

    Jaglin, Sylvy

    2017-01-01

    The role of cities, as places and drivers of the energy transition is increasingly recognized. The research project Termos tested the robustness of this assumption in four cities of emerging countries by asking two questions: to what extent do urban local actors really drive an urban energy transition and of what kind? To what extent are their actions supporting an urban territorialisation of energy systems? The paper first presents the findings of this comparative research, which he then extends with the case study of Cape Town. It analyzes why, despite their energy and environmental voluntarism, the municipality have little room of manoeuvre, while the changes observed seem to strengthen the stranglehold of the 'central sphere' in the energy system. Analyzing this as the expression of a conflict between a strong national electricity sector and an alternative approach to energy issues carried by urban actors, it highlights the resulting tensions and their impact on the municipal actions, both limited by resistance but also 'swallowed up' by actors from the central sphere. The paper finally draws lessons from this example to enrich the general analysis of dynamics observed in other cities of emerging countries

    2017-07-01

    The purpose of this research is to investigate teens' perceived social norms and whether providing normative information can reduce distracted driving behaviors among them. Parents are among the most important social referents for teens; they have significant influences on teens' driving behaviors, including distracted driving which significantly contributes to teens' crash risks. Social norms interventions have been successfully applied in various domains including driving; however, this approach is yet to be explored for mitigating driver distraction among teens. Forty teens completed a driving simulator experiment while performing a self-paced visual-manual secondary task in four between-subject conditions: a) social norms feedback that provided a report at the end of each drive on teens' distracted driving behavior, comparing their distraction engagement to their parent's, b) post-drive feedback that provided just the report on teens' distracted driving behavior without information on their parents, c) real-time feedback in the form of auditory warnings based on eyes of road-time, and d) no feedback as control. Questionnaires were administered to collect data on these teens' and their parents' self-reported engagement in driver distractions and the associated social norms. Social norms and real-time feedback conditions resulted in significantly smaller average off-road glance duration, rate of long (>2s) off-road glances, and standard deviation of lane position compared to no feedback. Further, social norms feedback decreased brake response time and percentage of time not looking at the road compared to no feedback. No major effect was observed for post-drive feedback. Questionnaire results suggest that teens appeared to overestimate parental norms, but no effect of feedback was found on their perceptions. Feedback systems that leverage social norms can help mitigate driver distraction among teens. Overall, both social norms and real-time feedback induced

    2003-04-01

    For the philosophy of medicine, there are two things of interest about the stoic account of moral norms, quite apart from whether the rest of stoic ethical theory is compelling. One is the stoic version of naturalism: its account of practical reasoning, its solution to the is/ought problem, and its contention that norms for creating, sustaining, or restoring human health are tantamount to moral norms. The other is the stoic account of human agency: its description of the intimate connections between human health, rational agency, and moral norms. There is practical guidance to be gained from exploring those connections, whether or not one is ready to follow stoic moral theory all the way to its austere end.

    This paper describes initial analysis of branching points on a set of transition pathways to a UK low carbon electricity future by 2050. As described in other papers in this special issue, we are exploring and analysing a set of core transition pathways, based on alternative governance patterns in which the ‘logics’ of market actors, government actors and civil society actors, respectively dominate. This core pathway analysis is enhanced by analyses of branching points within and across the pathways, which informs how competition between different logics plays out at key decision points. Branching points are defined as key decision points at which choices made by actors, in response to internal or external stresses or triggers, determine whether and in what ways the pathway is followed. A set of initial branching points for our three core transition pathways is identified through project and stakeholder workshops, and drawing on analysis of actors’ choices and responses at past branching points in energy system transitions. The potential responses of the actors are identified at these branching points, and risk mitigation strategies are formulated for the dominant actors to reinforce that pathway, as well as opportunities for actors to move away from the pathway. - Highlights: Transition Pathways is analysing three potential pathways to a low carbon future. ► Stresses lead to branching points, where actors make choices, creating pathways. ► These choices may lead to path-dependency. ► Differences in governance logics within transition pathways are also analysed. ► Studying branching points adds theoretical understanding and policy relevance to TP.

    Japan introduced a nationwide long-term care insurance (LTCI) system in 2000, making long-term care (LTC) a right for older adults regardless of income and family availability. To shed light on its implications for family caregiving, we investigated perceived filial obligation norms among coresident primary family caregivers before and after the policy change. Descriptive and multiple regression analyses were conducted to examine changes in perceived filial obligation norms and its subdimensions (financial, physical, and emotional support), using 2-wave panel survey data of coresident primary family caregivers (N = 611) in 1 city. The baseline survey was conducted in 1999, and a follow-up survey 2 years later. On average, perceived filial obligation norms declined (p family caregivers. In particular, physical support, which Japan's LTC reform targeted, declined significantly among daughters and daughters-in-law (p perceived filial obligation norms after the policy introduction than sons and daughters (p < .01 and p < .05, respectively), controlling for the baseline filial obligation and situational factors. Our research indicates declining roles of daughters-in-law in elder care during Japan's LTCI system implementation period. Further international efforts are needed to design and implement longitudinal studies that help promote understanding of the interplay among national LTC policies, social changes, and caregiving norms and behaviors. © The Author 2013.

    Naturally Occureed Radioactive Material (NORM) generated from the origin of earth can be found all around us and even people who are not engaged in the work related to radiation have been exposed to unnecessary radiation. This NORM has a potential risk provided that is concentrated or transformed by artificial activities. Likewise, a development of fast measruement method of NORM is emerging to prevent the radiation exposure of the general public and person engaged in the work related to the type of business related thereto who uses the material in which NORM is concentrated or transfromed. Based on such a background, many of countries have tried to manage NORM and carried out regulatory legislation. To effienctly manage NORM, there is need for developing new measurement to quickly and accurately analyze the nuclide and concentration. In this study, development of the fast and reliable measurement was carried out. In addition to confirming the reliability of the fast measurement, we have obtained results that can suggest the possibility of developing another fast measurement. Therefore, as a follow-up, it is possible to develop another fast analytical measurement afterwards. The results of this study will be very useful for the regulatory system to manage NORM. In this study, a review of two indirect measurement methods of NORM U-238 that has used HPGe on the basis of the equilibrium theory of relationships of mother and daughter nuclide at decay-chain of NORM U-238 has been carried out. For comparative study(in order to know reliabily), direct measurement that makes use of alpha spectrometer with complicated pre-processing process was implemented.

    Full Text Available Much of the discourse surrounding national intercity passenger rail service in the United States revolves around why it has lagged so far behind European and Asian counterparts. However, a more interesting question might be why it has survived despite competition from faster, more nimble transport modes, discriminatory public policy, and the ascension of neoliberal discourse hostile to public endeavor. This paper uses the concept of durability in actor-network theory to offer some insights into how the system has achieved a remarkable but problematic stability, and how that durability relates to an imagined role for national intercity passenger rail in a future of increasingly constrained material resources. This paper also demonstrates the application of actor-network theory (ANT in a way that can serve as a useful introduction to and template for the use of that methodology.

    Science.gov (United States)

    ACToR (Aggregated Computational Toxicology Resource) is a centralized database repository developed by the National Center for Computational Toxicology (NCCT) at the U.S. Environmental Protection Agency (EPA). Free and open source tools were used to compile toxicity data from over 1,950 public sources. ACToR contains chemical structure information and toxicological data for over 558,000 unique chemicals. The database primarily includes data from NCCT research programs, in vivo toxicity data from ToxRef, human exposure data from ExpoCast, high-throughput screening data from ToxCast and high quality chemical structure information from the EPA DSSTox program. The DSSTox database is a chemical structure inventory for the NCCT programs and currently has about 16,000 unique structures. Included are also data from PubChem, ChemSpider, USDA, FDA, NIH and several other public data sources. ACToR has been a resource to various international and national research groups. Most of our recent efforts on ACToR are focused on improving the structural identifiers and Physico-Chemical properties of the chemicals in the database. Organizing this huge collection of data and improving the chemical structure quality of the database has posed some major challenges. Workflows have been developed to process structures, calculate chemical properties and identify relationships between CAS numbers.

Owing to the secularized society in which we live today the well known Martin Buber once spoke of the eclipse of the light of heaven as an eclipse of God and, we may add, an eclipse also of moral norms. A theocentric basis for moral norms should be accepted as well as the fact that the whole of creation is subject unconditionally to his cosmonomic order. Consequently there is a concrete demand or claim on man in the situation he confronts, which cannot be reduced to an application of general moral norms to the situation concerned. God does speak to us through historical situations as well. We shall have to judge the concrete historical situation in its immediate hic et nunc call on us in the light of the will and law of God, as they are revealed to us in his Word.

  13. Low gamma counting for measuring NORM/TENORM with a radon reducing system

    International Nuclear Information System (INIS)

    Paschoa, A.S.

    2000-01-01

    A detection system for counting low levels of gamma radiation was developed by upgrading an existing whole body counter. The main shielding is a rectangular chamber made of 18 metric tons of steel fabricated before the World War II. The ceiling and floor are 0.20 m in thickness, and the walls 0.10 m. The internal walls, the ceiling and the floor of the chamber are covered with copper sheets 1.0 mm in thickness. The new detection system consists of a stainless steel hollow cylinder with variable circular apertures in the cylindrical wall and in the base, to allow NaI(Tl) and/or HPGe detectors in its interior. This counting system is mounted inside the larger shielding chamber, which in turn is located in a subsurface air conditioned room. The air exchange rate between the subsurface room and the exterior is kept to a minimum, to avoid large amounts of radon from outdoors to enter the subsurface room. The floor, the walls, and the ceiling of this subsurface room were painted with materials impermeable to radon gas. The access to the subsurface room is made from a larger entrance room through a tunnel plus a glass ante-room to decrease still further the air- exchange rate. The stainless steel hollow cylinder houses the sample to be measured and the detector. This cylinder can be filled with hyper pure nitrogen gas at a slighter positive pressure before counting a sample to prevent radon to enter the volume surrounding the detector. The low radon concentration near the detector minimizes the contribution of the 214 Bi photopeaks to the gamma spectra. The samples can be placed inside the cylinder in a variety of configurations. Spectra of selected gamma emitters were obtained with samples and detectors in several configurations. Gamma spectra were obtained for each of those configurations to illustrate the reduction the counting background. The reduction of gamma radiation background near the detector allows one to count naturally occurring radioactive materials (NORM

  16. Bundles of Norms About Teen Sex and Pregnancy.

    2015-09-01

    Teen pregnancy is a cultural battleground in struggles over morality, education, and family. At its heart are norms about teen sex, contraception, pregnancy, and abortion. Analyzing 57 interviews with college students, we found that "bundles" of related norms shaped the messages teens hear. Teens did not think their communities encouraged teen sex or pregnancy, but normative messages differed greatly, with either moral or practical rationalizations. Teens readily identified multiple norms intended to regulate teen sex, contraception, abortion, childbearing, and the sanctioning of teen parents. Beyond influencing teens' behavior, norms shaped teenagers' public portrayals and post hoc justifications of their behavior. Although norm bundles are complex to measure, participants could summarize them succinctly. These bundles and their conflicting behavioral prescriptions create space for human agency in negotiating normative pressures. The norm bundles concept has implications for teen pregnancy prevention policies and can help revitalize social norms for understanding health behaviors. © The Author(s) 2014.

    This article provides an in-depth assessment of lone actor terrorists' attack planning and preparation. A codebook of 198 variables related to different aspects of pre-attack behavior is applied to a sample of 55 lone actor terrorists. Data were drawn from open-source materials and complemented where possible with primary sources. Most lone actors are not highly lethal or surreptitious attackers. They are generally poor at maintaining operational security, leak their motivations and capabilities in numerous ways, and generally do so months and even years before an attack. Moreover, the "loneness" thought to define this type of terrorism is generally absent; most lone actors uphold social ties that are crucial to their adoption and maintenance of the motivation and capability to commit terrorist violence. The results offer concrete input for those working to detect and prevent this form of terrorism and argue for a re-evaluation of the "lone actor" concept. © 2017 The Authors.

    2010-11-01

    Alcohol use among college students has been associated with injunctive norms, which refer to the perceived acceptability of excessive drinking, and descriptive norms, which refer to perceptions of actual drinking. The purpose of this study was to examine the effect of a brief injunctive norms manipulation on both injunctive and descriptive norms about drinking alcohol and to explore differences in the malleability of norms across referent groups, sex, and gender role. Participants were 265 undergraduates (43% male, 70% freshmen) who completed a web-based survey for course credit. A randomly selected half was exposed to a page of information-based feedback about typical student injunctive norms. Relative to the control condition, the manipulation produced lower injunctive and descriptive norms related to typical students' drinking but no change in either type of norm related to close friends. Femininity was associated with less permissive normative beliefs about the acceptability of excessive drinking whereas masculinity was associated with elevated perceptions of peer drinking, but neither sex nor gender role moderated the manipulation effect. We conclude that perceptions of peer approval of drinking are malleable with a very brief information-based manipulation. Copyright 2010 Elsevier Ltd. All rights reserved.

    This paper uses new data from the Los Angeles Family and Neighborhood Survey (L.A. FANS) to examine how neighborhood norms shape teenagers’ substance use. Specifically, it takes advantage of clustered data at the neighborhood level to relate adult neighbors’ attitudes and behavior with respect to smoking, drinking, and drugs, which we treat as norms, to teenagers’ own smoking, drinking, and drug use. We use hierarchical linear models to account for parents’ attitudes and behavior and other characteristics of individuals and families. We also investigate how the association between neighborhood norms and teen behavior depends on: (1) the strength of norms, as measured by consensus in neighbors’ attitudes and conformity in their behavior; (2) the willingness and ability of neighbors to enforce norms, for instance, by monitoring teens’ activities; and (3) the degree to which teens are exposed to their neighbors. We find little association between neighborhood norms and teen substance use, regardless of how we condition the relationship. We discuss possible theoretical and methodological explanations for this finding. PMID:18496598

    This paper investigates the effects of information feedback mechanisms on electricity and heating usage at a student hall of residence in London. In a randomised control trial, we formulate different treatments such as feedback information and norms, as well as prize competition among subjects. We show that information and norms lead to a sharp – more than 20% - reduction in overall energy consumption. Because participants do not pay for their energy consumption this response cannot be driven by cost saving incentives. Interestingly, when combining feedback and norms with a prize competition for achieving low energy consumption, the reduction effect – while present initially – disappears in the long run. This could suggest that external rewards reduce and even destroy intrinsic motivation to change behaviour. - Highlights: •We investigate the effect of information feedback on residential energy consumption. •A RCT tests whether norms affect the decisions of price-indifferent participants. •Feedback mechanisms and norms reduce energy consumption by 22% on average. •Introducing prize competition dissipates the impact of information feedback and norms.

  1. Using multiscale norms to quantify mixing and transport

    Thiffeault, Jean-Luc

    2012-01-01

    Mixing is relevant to many areas of science and engineering, including the pharmaceutical and food industries, oceanography, atmospheric sciences and civil engineering. In all these situations one goal is to quantify and often then to improve the degree of homogenization of a substance being stirred, referred to as a passive scalar or tracer. A classical measure of mixing is the variance of the concentration of the scalar, which is the L 2 norm of a mean-zero concentration field. Recently, other norms have been used to quantify mixing, in particular the mix-norm as well as negative Sobolev norms. These norms have the advantage that unlike variance they decay even in the absence of diffusion, and their decay corresponds to the flow being mixing in the sense of ergodic theory. General Sobolev norms weigh scalar gradients differently, and are known as multiscale norms for mixing. We review the applications of such norms to mixing and transport, and show how they can be used to optimize the stirring and mixing of a decaying passive scalar. We then review recent work on the less-studied case of a continuously replenished scalar field—the source–sink problem. In that case the flows that optimally reduce the norms are associated with transport rather than mixing: they push sources onto sinks, and vice versa. (invited article)

    Full Text Available Because of the significant analytical advantages, the author prefers social action as initial sociological concept in the relation to social phenomenon. Its basic elements are: actors, subjects and tools, needs and interests, values and norms, positions and roles. Actors set in motion and unify the rest of elements, guide to the magic triangle of sociology (movement, change, order, reaffirm actor paradigm to systemic paradigm. Subjects and tools materialize an action and its overestimate results in technological determinism or (by means of property as institutional appropriation of nature in the (unclassed historical type of society. Needs and interests are the basis of person's motivation and starting point for depth analysis of sociability. The expansion of legitimate interests circle develops techniques of normative regulation. Values and norms guide to institutional-organizational, positions to vertical and roles to horizontal structure. Values give the meaning to the action as well as to human existence, they are orientations of motivate system of personality but also basic aspect of society. As abstractions, values are latent background of norms and they tell to us what to do, and norms how to do something. Norms are specified instructions for suitable behavior Without normative order, not to be possible the satisfying of needs and the conciliation of interests. Riches, power and prestige are components of social position, and legal status is the determination of rights and obligations of the position. Roles are normative expectation of behavior. Toward kinds of sanctions roles are classified. Roles but also other elements of social action are starting point for sociological analysis of legal norms and institutes. On the other side, the observation of legal component of social actions enriches, strengths and precises sociological analysis of them.

    In recent years, the use of learning management system by universities has been increasingly growing. However, the results of several studies have revealed that students do not fully use the information systems. The present study proposes a model which investigates the influence of three constructs of perceived ease of use, perceived usefulness, and subjective norm on behavior intention to use of learning management system. The sample size was 216 Malaysian undergraduate students. The results of the study revealed that the proposed model accounts for 31.1 % variance of behavior intention to use.

    Full Text Available Consumer attitudes toward consuming and buying locally produced food are well studied. By contrast, the topic of consumer preferences for local food, with a special emphasis on the role of norms, still lacks empirical evidence. To study the influence of norms and morals on the intention to buy local food products, a quantitative study (N = 327 focusing on external social and internalized moral norms was conducted using the constructs of the theory of planned behavior in combination with an extended norm taxonomy and the perceived consumer effectiveness measure. The norm constructs consisted of two different personal norms, integrated and introjected, and two social norms, descriptive and injunctive. In a factor analysis, two factors for social norms but only one for personal norms were obtained. Multiple regressions explained 50 percent of the variance in intentions and 29 percent of the variance in past behavior. Norm constructs were proven important in the model, as personal norms had the largest effect among all constructs on intentions, and descriptive norms strongly influenced past behavior. An additional mediation analysis showed that personal norms were internalized social injunctive norms and that intentions mediated the relationship between all constructs. The implications of the findings and recommendations for future research are given accordingly.

    Related studies with the presence of NORMs in Costa Rica were developed. CICANUM has had equipment and personnel to perform analysis using gamma spectroscopy (for solid and liquid samples), beta spectroscopy (for liquid milk samples and water), alpha spectroscopy (water samples). These techniques are frequently used in the analysis for food purchased from stores, monitoring, export (safety certicates), directly from the farm (research and projects ARCAL), several matrices (meristems, iron, etc..). The CICANUM supported by the Universidad de Costa Rica and the Laboratorio de Espectroscopia Gamma has participated in various projects by the IAEA, in research on food, marine species, quality assurance, development of reference material. The term NORMs is used to distinguish natural radioactive elements of radioactive elements of anthropogenic origin, among which are those produced by: terrestrial, mediums cosmogenic and industrial. One conclusion is that human activity has been responsible for increasing exposure of people to ionizing radiation. This increase has resulted of the production of coal, natural gas, mining and fossil fuels, and the use of fertilizers. Radon trapped in the rocks is released when performing scans or during extraction. (author) [es

    Social norms regulate behavior, and changes in norms have a great impact on society. In most modern societies, norms change through interpersonal communication and persuasive messages found in media. Here, we examined the neural basis of persuasion-induced changes in attitude toward and away from norms using fMRI. We measured brain activity while human participants were exposed to persuasive messages directed toward specific norms. Persuasion directed toward social norms specifically activated a set of brain regions including temporal poles, temporo-parietal junction, and medial prefrontal cortex. Beyond these regions, when successful, persuasion away from an accepted norm specifically recruited the left middle temporal and supramarginal gyri. Furthermore, in combination with data from a separate attitude-rating task, we found that left supramarginal gyrus activity represented participant attitude toward norms and tracked the persuasion-induced attitude changes that were away from agreement.

    Quantum coherence plays a central role in various research areas. The l1-norm of coherence is one of the most important coherence measures that are easily computable, but it is not easy to find a simple interpretation. We show that the l1-norm of coherence is uniquely characterized by a few simple axioms, which demonstrates in a precise sense that it is the analog of negativity in entanglement theory and sum negativity in the resource theory of magic-state quantum computation. We also provide an operational interpretation of the l1-norm of coherence as the maximum entanglement, measured by the negativity, produced by incoherent operations acting on the system and an incoherent ancilla. To achieve this goal, we clarify the relation between the l1-norm of coherence and negativity for all bipartite states, which leads to an interesting generalization of maximally correlated states. Surprisingly, all entangled states thus obtained are distillable. Moreover, their entanglement cost and distillable entanglement can be computed explicitly for a qubit-qudit system.

    In the West, limited government capacity to solve environmental problems has triggered the rise of a variety of "nonstate actors" to supplement government efforts or provide alternative mechanisms for addressing environmental issues. How does this development - along with our efforts to understand it - map onto environmental governance processes in China? China's efforts to address environmental issues reflect institutionalized governance processes that differ from parallel western processes in ways that have major consequences for domestic environmental governance practices and the governance of China "going abroad." China's governance processes blur the distinction between the state and other actors; the "shadow of the state" is a major factor in all efforts to address environmental issues. The space occupied by nonstate actors in western systems is occupied by shiye danwei ("public service units"), she hui tuanti ("social associations") and e-platforms, all of which have close links to the state. Meanwhile, international NGOs and multinational corporations are also significant players in China. As a result, the mechanisms of influence that produce effects in China differ in important ways from mechanisms familiar from the western experience. This conclusion has far-reaching implications for those seeking to address global environmental concerns, given the importance of China's growing economy and burgeoning network of trade relationships.

  13. Social health insurance without corporate actors: changes in self-regulation in Germany, Poland and Turkey.

    2013-06-01

    Social health insurance in Western Europe has for many years been characterized by self-regulation in which specific conditions of healthcare financing and provision have been regulated by social-insurance institutions through mutual self-governance. However, the principle of self-regulation has recently been weakened by increased state regulation and market competition, which were introduced in response to economic and social changes. Even in Germany, which has been regarded as an "ideal-type" health insurance system and in which self-regulation remains at the core of healthcare governance, more direct state intervention has gained in importance. On the other hand, in countries such as Poland and Turkey, where this tradition of self-regulation is missing, social health insurance is deemed a financing instrument but not an instrument of governance and corporate actors are not accorded a significant role in regulation. This article investigates how social health insurance systems are regulated in contexts in which corporate actors' role is either diminishing or absent by focusing on three crucial areas of regulation: financing, the remuneration of medical doctors, and the definition of the healthcare benefit package. In Germany, state regulation has increased in healthcare financing and remuneration while the role of corporate actors has grown in the definition of the benefits package. In Poland and Turkey, on the other hand, reforms have maintained the status quo in terms of the strong regulatory, budgetary, and managerial powers of the state and very limited involvement of corporate actors.

  14. Generalized Schmidt decomposability and its relation to projective norms in multipartite entanglement

    International Nuclear Information System (INIS)

    Sokoli, Florian; Alber, Gernot

    2014-01-01

    Projective norms are capable of measuring entanglement of multipartite quantum states. However, typically, the explicit computation of these distance-based geometric entanglement monotones is very difficult even for finite dimensional systems. Motivated by the significance of Schmidt decompositions for our quantitative understanding of bipartite quantum entanglement, a generalization of this concept to multipartite scenarios is proposed, in the sense that generalized Schmidt decomposability of a multipartite pure state implies that its projective norm can be calculated in a simple way analogous to the bipartite case. Thus, this concept of generalized Schmidt decomposability of multipartite quantum states is linked in a natural way to projective norms as entanglement monotones. Therefore, it may not only be a convenient tool for calculations, but may also shed new light onto the intricate features of multipartite entanglement in an analogous way as the ‘classical’ Schmidt decomposition does for bipartite quantum systems.

    2005-01-01

    We calculate and identify the counterparts of zero-norm states in the old covariant first quantized (OCFQ) spectrum of open bosonic string in two other quantization schemes of string theory, namely, the light-cone Del Giudice-Di Vecchia-Fubine zero-norm states and the off-shell Becchi-Rouet-Stora-Tyutin (BRST) zero-norm states (with ghost) in the Witten string field theory (WSFT). In particular, special attention is paid to the interparticle zero-norm states in all quantization schemes. For the case of the off-shell BRST zero-norm states, we impose the no-ghost conditions and recover exactly two types of on-shell zero-norm states in the OCFQ string spectrum for the first few low-lying mass levels. We then show that off-shell gauge transformations of WSFT are identical to the on-shell stringy gauge symmetries generated by two types of zero-norm states in the generalized massive σ-model approach of string theory. The high-energy limit of these stringy gauge symmetries was recently used to calculate the proportionality constants, conjectured by Gross, among high-energy scattering amplitudes of different string states. Based on these zero-norm state calculations, we have thus related gauge symmetry of WSFT to the high-energy stringy symmetry of Gross

    Full Text Available El presente trabajo pretendió reflexionar a partir de la teoría del actor-red en las mediaciones que hicieron posible y determinaron la proclamación de la ley 975 de 2005 o ley de justicia y paz. Se concluye que existieron diversos actores humanos y no humanos que fueron enrolados con el objetivo de expedir una ley que derivó en un proceso de impunidad y legitimación de la escalada paramilitar en Colombia; además se establece el plano jurídico como un espacio de disputas donde los intereses de los victimarios se enfrentan con los intereses de las víctimas en un juego político que ubica a estos últimos actores en nuevas situaciones de victimización.

  17. Exploring the Obstacles to Implementing Economic Mechanisms to Stimulate Antibiotic Research and Development: A Multi-Actor and System-Level Analysis.

    This Article examines the potential stakeholder-related obstacles hindering the implementation of mechanisms to re-ignite the development of novel antibiotics. Proposed economic models and incentives to drive such development include: Public Funding of Research and Development ("R&D"), Tax Incentives, Milestone Prizes, End Payments, Intellectual Property ("IP") and Exclusivity Extensions, Pricing and Reimbursement Incentives, Product Development Partnerships ("PDPs"), and the Options Market for Antibiotics model. Drawing on personal experience and understanding of the antibiotic field, as well as stakeholder consultation and numerous expert meetings within the DRIVE-AB project and Uppsala Health Summit 2015, the Authors identify obstacles attributable to the following actors: Universities and Research Institutes, Small and Medium-sized Enterprises ("SMEs"), Large Pharmaceutical Companies, Marketing Approval Regulators, Payors, Healthcare Providers, National Healthcare Authorities, Patients, and Supranational Institutions. The analysis also proposes a characterization and ranking of the difficulty associated with implementing the reviewed mechanisms. Public Funding of R&D, Pricing and Reimbursement Incentives, and PDPs are mechanisms expected to meet highly systemic barriers (i.e., obstacles across the entire antibiotic value chain), imposing greater implementation challenges in that they require convincing and involving several motivationally diverse actors in order to have much effect.

    The focus is on GAVE as an integral multi-actor process, as a collaboration process in which the parties have to find each other. The reason for this multi-actor approach is that the parties themselves have to realise the importance of sustainable energy. A multi-actor approach uses this crucial fact as the starting point. By means of the use of specific multi-actor methods and insights, it is possible during the collaboration process to develop a clear idea of the content of the joint path and the intended collaborative future, while paying specific attention to the individual roles of the players. Based on this, a well- considered and promising realisation path can be followed. The objective of this study is to illustrate - on the basis of two GAVE options - how the multi-actor approach can support the GAVE programme. In doing this, emphasis is placed on examples, the demonstration of added value of such an approach, and making recommendations for the future. Two experiments have been carried out on the basis of the Trinity approach. The Trinity approach is a set of methods specifically developed for supporting change processes which involve many parties (i.e. multi-actor processes). Trinity helps those involved to obtain a clear picture of both the route to be followed and the future situation to be aimed at. The term 'picture' must be understood literally: an important aspect of Trinity is the collaboration and communication with multi-actor models (also referred to as actorprints). By means of a diagram technique (figures and arrows) these models demonstrate the cohesion between the roles and activities of the various parties involved. The modelling process is instrumental in this; the actual result is that the image that is developed is formed and backed up by the participants in the process. Within these experiments, we have, so far, worked mainly in the shadow of the current GAVE process. A forceful participative use of the actor approach is

    Gabriel, Allison S; Daniels, Michael A; Diefendorff, James M; Greguras, Gary J

    2015-05-01

    Research on emotional labor focuses on how employees utilize 2 main regulation strategies-surface acting (i.e., faking one's felt emotions) and deep acting (i.e., attempting to feel required emotions)-to adhere to emotional expectations of their jobs. To date, researchers largely have considered how each strategy functions to predict outcomes in isolation. However, this variable-centered perspective ignores the possibility that there are subpopulations of employees who may differ in their combined use of surface and deep acting. To address this issue, we conducted 2 studies that examined surface acting and deep acting from a person-centered perspective. Using latent profile analysis, we identified 5 emotional labor profiles-non-actors, low actors, surface actors, deep actors, and regulators-and found that these actor profiles were distinguished by several emotional labor antecedents (positive affectivity, negative affectivity, display rules, customer orientation, and emotion demands-abilities fit) and differentially predicted employee outcomes (emotional exhaustion, job satisfaction, and felt inauthenticity). Our results reveal new insights into the nature of emotion regulation in emotional labor contexts and how different employees may characteristically use distinct combinations of emotion regulation strategies to manage their emotional expressions at work.

    2003-04-01

    In November 2002 a special exhibition on climate issues opened in the German Museum for Science and Techniques ('Deutsches Museum') in Munich. Within this exposition we present an interactive game in which visitors control future climate policy by adopting the role of either the government, a CEO (Chief Executive Officer) of a global company or a typical private household of an industrialized country. The players endeavor to maintain a sustainable climate in the future (global goal) while pursuing their own individual welfare goals. Task of the exhibition visitor is to combine the personal interests of the actor he is adopting with the global goal. The individual goal of government is maintain economic growth while avoiding conflicts due to inter-regional or societal inequalities. The CEO seeks to maximize total profits (business earnings). The goal of households is to maximize wages and interest earnings. The evolution of the economic system and climate is governed by the decisions of the actors. Government sets economic side conditions in terms of carbon taxes, subsidies for R&D or market infusion support for climate-friendly technologies, and transfers development aid to less advanced regions. The CEOs decide how much to invest in a number of alternative investment options and in which region. Households influences the economy by their purchasing and savings decisions. The model considers four regions, three real actors (mentioned above) and two different goods (climate-adverse and a climate-friendly). We introduce four different kinds of energy (coal, oil/gas, nuclear, renewable). A World Bank handles money flows. At different points in time the actors can cooperate with other actors in order to reach the global goal Stochastic elements regarding future technology and future climate are included. A touch-screen monitor with user friendly interface is used to present animations and videos. An animated climate scientist uses a climate simulator to compute future

    Qubbaj, Murad R.; Muneepeerakul, Rachata

    2012-11-01

    Recent mathematical dynamical models of the conflict between two different actors, be they nations, groups, or individuals, have been developed that are capable of predicting various outcomes depending on the chosen feedback strategies, initial conditions, and the previous states of the actors. In addition to these factors, this paper examines the effect of time delayed feedback on the conflict dynamics. Our analysis shows that under certain initial and feedback conditions, a stable neutral equilibrium of conflict may destabilize for some critical values of time delay, and the two actors may evolve to new emotional states. We investigate the results by constructing critical delay surfaces for different sets of parameters and analyzing results from numerical simulations. These results provide new insights regarding conflict and conflict resolution and may help planners in adjusting and assessing their strategic decisions.

    Management of NORM/TENORM waste is now to be an issue and discussed in many international conferences and seminars. This paper describes the status of the management of NORM/TENORM waste including the origin of the waste, regulations and assessment of waste disposal. Several countries have established the regulation for NORM/TENORM waste; however the IAEA has not yet published guideline for management of NORM/TENORM. There are many options for disposal of NORM/TENORM waste based on standard of the radioactive waste disposal. The decision and policy on management of NORM/TENORM waste must be conducted carefully due to the social and economical impacts. (author)

    Recently, Lael and Nourouzi [Some results on the IF-normed spaces. Chaos, Solitons and Fractals 2006; doi:10.1016/j.chaos.2006.10.019] introduced and studied a new notation of IF-normed spaces by using the idea of intuitionistic fuzzy normed spaces due to Saadati and Park [On the intuitionistic fuzzy topological spaces. Chaos, Solitons and Fractals 2006;27:331-44], a special continuous t-norm i.e. min and a special continuous s-norm i.e. max. In this note, we consider the modified definition of IF-normed space i.e. LF-normed spaces and prove the open mapping and closed graph theorems for this space using arbitrary continuous t-norm.

  5. Silence and table manners: when environments activate norms.

    Joly, Janneke F; Stapel, Diederik A; Lindenberg, Siegwart M

    2008-08-01

    Two studies tested the conditions under which an environment (e.g., library, restaurant) raises the relevance of environment-specific social norms (e.g., being quiet, using table manners). As hypothesized, the relevance of such norms is raised when environments are goal relevant ("I am going there later") and when they are humanized with people or the remnants of their presence (e.g., a glass of wine on a table). Two studies show that goal-relevant environments and humanized environments raise the perceived importance of norms (Study 1) and the intention to conform to norms (Study 2). Interestingly, in both studies, these effects reach beyond norms related to the environments used in the studies.

    International audience; In an environment marked by ever-greater international competition, wine sector companies have been seriously questioning the structure of their entire logistics chain. This is due to the emergence of new actors (i.e., large retailers); the diversification of service providers' product offers; and the different rapprochements between actors in this branch. These are all signals that have caused companies to question their logistics strategies as shown in the ISLI survey.

  8. A New Replication Norm for Psychology

    Directory of Open Access Journals (Sweden)

    Etienne P LeBel

    2015-10-01

    Full Text Available In recent years, there has been a growing concern regarding the replicability of findings in psychology, including a mounting number of prominent findings that have failed to replicate via high-powered independent replication attempts. In the face of this replicability “crisis of confidence”, several initiatives have been implemented to increase the reliability of empirical findings. In the current article, I propose a new replication norm that aims to further boost the dependability of findings in psychology. Paralleling the extant social norm that researchers should peer review about three times as many articles that they themselves publish per year, the new replication norm states that researchers should aim to independently replicate important findings in their own research areas in proportion to the number of original studies they themselves publish per year (e.g., a 4:1 original-to-replication studies ratio. I argue this simple approach could significantly advance our science by increasing the reliability and cumulative nature of our empirical knowledge base, accelerating our theoretical understanding of psychological phenomena, instilling a focus on quality rather than quantity, and by facilitating our transformation toward a research culture where executing and reporting independent direct replications is viewed as an ordinary part of the research process. To help promote the new norm, I delineate (1 how each of the major constituencies of the research process (i.e., funders, journals, professional societies, departments, and individual researchers can incentivize replications and promote the new norm and (2 any obstacles each constituency faces in supporting the new norm.

  9. The European Union as a Comprehensive Police Actor

    Directory of Open Access Journals (Sweden)

    Stephen Anthony Rozée

    2011-12-01

    Full Text Available The European Union (EU has responded to changing security threats by seeking to increase cooperation between the law enforcement agencies of the Member States, granting further powers to Europol and other intelligence-sharing institutions, and by undertaking police missions beyond EU borders. The literature relating to EU policing is generally focused on the ‘internal’ and ‘external’ dimensions, or on specific aspects of police activity. This tendency to concentrate on narrow or isolated areas of policing has led to a significant gap regarding the broader analysis of the EU as a comprehensive police actor. Important questions about the nature of EU policing as a whole, as well as the contribution of policing activities to the EU’s security agenda, remain unexplored in the literature. This article aims to define what is meant by ‘comprehensive policing’ and to indentify criteria by which the comprehensiveness of EU-level policing may be measured. In addition to this, an integrated actorness/police comprehensiveness framework will be presented as a tool for assessing the EU as a comprehensive police actor.

  10. Solving of L0 norm constrained EEG inverse problem.

    2009-01-01

    l(0) norm is an effective constraint used to solve EEG inverse problem for a sparse solution. However, due to the discontinuous and un-differentiable properties, it is an open issue to solve the l(0) norm constrained problem, which is usually instead solved by using some alternative functions like l(1) norm to approximate l(0) norm. In this paper, a continuous and differentiable function having the same form as the transfer function of Butterworth low-pass filter is introduced to approximate l(0) norm constraint involved in EEG inverse problem. The new approximation based approach was compared with l(1) norm and LORETA solutions on a realistic head model using simulated sources. The preliminary results show that this alternative approximation to l(0) norm is promising for the estimation of EEG sources with sparse distribution.

    Regulation of radioactive material can occur at the Federal, State, and sometimes local level. In addition to regulations at the federal and state level, there are guidelines and standards that do not carry the weight of law, yet are often referenced. Neither the Nuclear Regulatory Commission (NRC) or Environmental Protection Agency (EPA) categorically regulates NORM at this time. However, many of the existing regulations and guidelines for licensed radioactive material can be applied by states and other regulatory agencies to NORM. The primary regulations covering radioactive materials and exposures were promulgated under the Atomic Energy Act (AEA) or 1954, as amended. NRC licenses and regulates civilian use of nuclear materials to protect public health and safety and the environment. NRC makes rules and sets standards for licensees and inspects the activities of licensees to insure that they do not violate safety rules. OSHA regulations for worker protection from exposures to radioactivity are contained in 29CFR1910.96. These standards are designed to protect workers from exposure to radiation in programs other than those regulated by OSHA. The Uranium Mill Tailings Control Act, with implementing regulations found in 40CFR192 were promulgated by the EPA for cleanup of uranium mill tailings. These standards are often used by states and other agencies in regulating cleanup of NORM. EPA is currently considering regulation of NORM on NRC and DOE facilities under 40CFR195

    2014-03-01

    The EQ-5D is a widely used preference-based measure. Normative data can be used as references to analyze the effects of healthcare, determine the burden of disease and enable regional or country comparisons. Population norms for the EQ-5D exist for other countries but have not been previously published for Portugal. The purpose of this study was to derive EQ-5D Portuguese population norms. The EQ-5D was applied by phone interview to a random sample of the Portuguese general population (n = 1,500) stratified by age, gender and region. The Portuguese value set was used to derive the EQ-5D index. Mean values were computed by gender and age groups, marital status, educational attainment, region and other variables to obtain the EQ-5D Portuguese norms. Health status declines with advancing age, and women reported worse health status than men. These results are similar to other EQ-5D population health studies. This study provides Portuguese population health-related quality of life data measured by the EQ-5D that can be used as population norms. These norms can be used to inform Portuguese policy makers, health care professionals and researchers in issues related to health care policy and planning and quantification of treatment effects on health status.

  13. Model Selection in Continuous Test Norming With GAMLSS.

    2017-06-01

    To compute norms from reference group test scores, continuous norming is preferred over traditional norming. A suitable continuous norming approach for continuous data is the use of the Box-Cox Power Exponential model, which is found in the generalized additive models for location, scale, and shape. Applying the Box-Cox Power Exponential model for test norming requires model selection, but it is unknown how well this can be done with an automatic selection procedure. In a simulation study, we compared the performance of two stepwise model selection procedures combined with four model-fit criteria (Akaike information criterion, Bayesian information criterion, generalized Akaike information criterion (3), cross-validation), varying data complexity, sampling design, and sample size in a fully crossed design. The new procedure combined with one of the generalized Akaike information criterion was the most efficient model selection procedure (i.e., required the smallest sample size). The advocated model selection procedure is illustrated with norming data of an intelligence test.

    Saadati and Park [Saadati R, Park JH, Chaos, Solitons and Fractals 2006;27:331-44] has recently introduced the notion of intuitionistic fuzzy normed space. In this paper, we study the concept of statistical convergence on intuitionistic fuzzy normed spaces. Then we give a useful characterization for statistically convergent sequences. Furthermore, we display an example such that our method of convergence is stronger than the usual convergence on intuitionistic fuzzy normed spaces

    Ngoufo R

    2014-06-01

    Full Text Available In many traditional societies, beliefs and taboos influence human behaviour towards the natural environment. Such beliefs and taboos are informal institutions where norms rather than official laws determine land use and nature protection in general and wildlife in particular. The present study on beliefs and taboos of the people of the northern periphery of the Korup National Park is an attempt to reveal how norms influence their relation to the environment. A total of 195 households were sampled through a household survey conducted in four villages. The results revealed that before the application of “modern” approaches for wildlife protection and management, the people relied on norms to establish a relationship with wildlife and nature. The enactment of the 1994 legislation on forest, wildlife and fisheries resulted in stiff resistance as it contradicts traditional norms. It was found that 57.4 % of the respondents still perceive wildlife as a resource that can never get extinct. Traditional norms had a differentiated impact especially on game protection. The study recommends that a wildlife benefiting code of beliefs and taboos is developed to provide a basis for establishing a synergy between park management laws and traditional belief/taboo systems that drive the management of wildlife.

    2016-04-01

    Full Text Available We aim at mapping out a detailed framework that reveals the proportionate flow of cassava and its products along the value chain (VC. Furthermore, we aim at establishing the role of institutions and the linkages between institutions and other VC actors that influence the cassava VC in Uganda. We use both primary and secondary data obtained from four regions in Uganda. Results show that farmers, processors, transporters, traders, consumers and institutions are the major actors. There are four categories of institutions, viz, government, non-government, community based organisations and international agencies. Roles performed by institutions include: development and enforcement of policies, Research and Development (R&D, capacity building, and creation of market access linkages for cassava and its products. Findings reveal that there is no clear nexus and no coordination among farmers/producers, processors, traders, transporters and consumers. However, institutions are well coordinated and play various roles along the VC to influence the dynamics of actors. Policy-wise it is important to establish strong private-public partnerships to bridge the impaired linkages between the actors (farmers/producers, processors, traders, transporters, and consumers and institutions. Strong partnerships are envisaged to reduce the associated transaction costs amongst the actors.

  20. Automatic extraction of property norm-like data from large text corpora.

    Science.gov (United States)

    Kelly, Colin; Devereux, Barry; Korhonen, Anna

    2014-01-01

    Traditional methods for deriving property-based representations of concepts from text have focused on either extracting only a subset of possible relation types, such as hyponymy/hypernymy (e.g., car is-a vehicle) or meronymy/metonymy (e.g., car has wheels), or unspecified relations (e.g., car--petrol). We propose a system for the challenging task of automatic, large-scale acquisition of unconstrained, human-like property norms from large text corpora, and discuss the theoretical implications of such a system. We employ syntactic, semantic, and encyclopedic information to guide our extraction, yielding concept-relation-feature triples (e.g., car be fast, car require petrol, car cause pollution), which approximate property-based conceptual representations. Our novel method extracts candidate triples from parsed corpora (Wikipedia and the British National Corpus) using syntactically and grammatically motivated rules, then reweights triples with a linear combination of their frequency and four statistical metrics. We assess our system output in three ways: lexical comparison with norms derived from human-generated property norm data, direct evaluation by four human judges, and a semantic distance comparison with both WordNet similarity data and human-judged concept similarity ratings. Our system offers a viable and performant method of plausible triple extraction: Our lexical comparison shows comparable performance to the current state-of-the-art, while subsequent evaluations exhibit the human-like character of our generated properties.

  1. Norms and customs: causally important or causally impotent?

    2010-01-01

    In this article, I argue that norms and customs, despite frequently being described as being causes of behavior in the social sciences and ordinary conversation, cannot really cause behavior. Terms like "norms" and the like seem to refer to philosophically disreputable disjunctive properties. More problematically, even if they do not, or even if there can be disjunctive properties after all, I argue that norms and customs still cannot cause behavior. The social sciences would be better off without referring to properties like norms and customs as if they could be causal.

  4. Evolution of generous cooperative norms by cultural group selection.

    Science.gov (United States)

    Scheuring, István

    2009-04-07

    Evolution of cooperative norms is studied in a population where individual- and group-level selection are both in operation. Individuals play indirect reciprocity game within their group. Individuals are well informed about the previous actions and reputations, and follow second-order norms. Individuals are norm-followers, and imitate their successful group mates. In contrast to previous models where norms classify actions deterministically, we assume that norms determine only the probabilities of actions, and mutants can differ in these probabilities. The central question is how a selective cooperative norm can emerge in a population where initially only non-cooperative norms were present. It is shown that evolution leads to a cooperative state if generous cooperative strategies are dominant, although the "always defecting" and the "always cooperating"-like strategies remain stably present. The characteristics of these generous cooperative strategies and the presence of always defecting and always cooperating strategies are in concordance with experimental observations.

    People across societies engage in costly sharing, but the extent of such sharing shows striking cultural variation, highlighting the importance of local norms in shaping generosity. Despite this acknowledged role for norms, it is unclear when they begin to exert their influence in development.

Additionally, we varied whether children were ...

  6. Not My Problem: Vicarious Conflict Adaptation with Human and Virtual Co-Actors

    Directory of Open Access Journals (Sweden)

    Michiel M. Spapé

    2016-04-01

    Full Text Available The Simon effect refers to an incompatibility between stimulus and response locations resulting in a conflict situation and, consequently, slower responses. Like other conflict effects, it is commonly reduced after repetitions, suggesting an executive control ability, which flexibly rewires cognitive processing and adapts to conflict. Interestingly, conflict is not necessarily individually defined: the Social Simon effect refers to a scenario where two people who share a task show a conflict effect where a single person does not. Recent studies showed these observations might converge into what could be called vicarious conflict adaptation, with evidence indicating that observing someone else’s conflict may subsequently reduce one’s own. While plausible, there is reason for doubt: both the social aspect of the Simon Effect, and the degree to which executive control accounts for the conflict adaptation effect, have become foci of debate in recent studies. Here, we present two experiments that were designed to test the social dimension of the effect by varying the social relationship between the actor and the co-actor. In Experiment 1, participants performed a conflict task with a virtual co-actor, while the actor-observer relationship was manipulated as a function of the similarity between response modalities. In Experiment 2, the same task was performed both with a virtual and with a human co-actor, while heart-rate measurements were taken to measure the impact of observed conflict on autonomous activity. While both experiments replicated the interpersonal conflict adaptation effects, neither showed evidence of the critical social dimension. We consider the findings as demonstrating that vicarious conflict adaptation does not rely on the social relationship between the actor and co-actor.

    Full Text Available This article shows how agent-based modeling allows us to explore the mechanisms of the dissemination of cultural norms and values both within one country and in the whole world. In recent years, this type of simulation is particularly prevalent in the analysis of international relations, becoming more popular than the system dynamics and discrete event simulation. The use of agent-based modeling in the analysis of international relations is connected with the agent-structure problem in international relations. Structure and agents act as interdependent and dynamically changing in the process of interaction between entities. Agent-structure interaction could be modeled by means of the theory of complex adaptive systems with the use of agent-based modeling techniques. One of the first examples of the use of agent-based modeling in political science is a model of racial segregation T. Shellinga. On the basis of this model, the author shows how the change in behavioral patterns at micro-level impacts on the macro-level. Patterns are changing due to the dynamics of cultural norms and values, formed by mass-media and other social institutes. The author shows the main areas of modern application of agent-based modeling in international studies including the analysis of ethnic conflicts, the formation of international coalitions. Particular attention is paid to Robert Axelrod approach based on the use of genetic algorithms to the spread of cultural norms and values. Agent-based modeling shows how to how to create such conditions that the norms that originally are not shared by a significant part of the population, eventually spread everywhere. Practical application of these algorithms is shown by the author of the article on the example of the situation in Ukraine in 2015-2016. The article also reveals the mechanisms of international spread of cultural norms and values. The main think-tanks using agent-based modeling in international studies are

  9. Bombing Alone: Tracing the Motivations and Antecedent Behaviors of Lone-Actor Terrorists*,†,‡

    Gill, Paul; Horgan, John; Deckert, Paige

    2014-01-01

    This article analyzes the sociodemographic network characteristics and antecedent behaviors of 119 lone-actor terrorists. This marks a departure from existing analyses by largely focusing upon behavioral aspects of each offender. This article also examines whether lone-actor terrorists differ based on their ideologies or network connectivity. The analysis leads to seven conclusions. There was no uniform profile identified. In the time leading up to most lone-actor terrorist events, other people generally knew about the offender’s grievance, extremist ideology, views, and/or intent to engage in violence. A wide range of activities and experiences preceded lone actors’ plots or events. Many but not all lone-actor terrorists were socially isolated. Lone-actor terrorists regularly engaged in a detectable and observable range of activities with a wider pressure group, social movement, or terrorist organization. Lone-actor terrorist events were rarely sudden and impulsive. There were distinguishable behavioral differences between subgroups. The implications for policy conclude this article. PMID:24313297

  10. Practicing governance towards equity in health systems: LMIC perspectives and experience.

    Gilson, Lucy; Lehmann, Uta; Schneider, Helen

    2017-09-15

    The unifying theme of the papers in this series is a concern for understanding the everyday practice of governance in low- and middle-income country (LMIC) health systems. Rather than seeing governance as a normative health system goal addressed through the architecture and design of accountability and regulatory frameworks, these papers provide insights into the real-world decision-making of health policy and system actors. Their multiple, routine decisions translate policy intentions into practice - and are filtered through relationships, underpinned by values and norms, influenced by organizational structures and resources, and embedded in historical and socio-political contexts. These decisions are also political acts - in that they influence who accesses benefits and whose voices are heard in decision-making, reinforcing or challenging existing institutional exclusion and power inequalities. In other words, the everyday practice of governance has direct impacts on health system equity.The papers in the series address governance through diverse health policy and system issues, consider actors located at multiple levels of the system and draw on multi-disciplinary perspectives. They present detailed examination of experiences in a range of African and Indian settings, led by authors who live and work in these settings. The overall purpose of the papers in this series is thus to provide an empirical and embedded research perspective on governance and equity in health systems.

    This study comprises three reports. The first one is an executive summary which focuses on the main aspects of the evolution of the activity in the biomass sector, and highlights factors of change and their strategic consequences. The second one proposes an overview of the situation of biomass French markets, analyses growth strategies adopted by actors of the biomass sector (development of new production capacities, international growth, development of strategies based on several energies, diversification of prospects, innovation and improvement of installation efficiency), and discusses the main strategic challenges on the medium term. The third report proposes a presentation of the context of French biomass markets (political, regulatory and energetic framework, energetic assessment and assessment of the waste-based sector, economic context, housing stock, and other contextual factors), a presentation of the biomass French market (data for 2005-2013, dynamics of three specific segments: solid biomass, renewable urban wastes, and biogas), and a description of the competitive landscape (economic structure, actors) and of the 15 main actors

    Full Text Available The purpose of this study was to create a norm reference of current grip and pinch strength norms for working-age Michigan adults. This normative study included a convenience sample of 179 volunteers who were employees at car plants in South East Michigan or hospital sites in West Michigan. Participants’ ages ranged from between 20 and 62 years of age with a mean age of 49.15 years. There were 78 females (44% and 101 males (56%. Subjects were classified by gender and in the age categories of ages 20 to 49 years and ages 50-62 years. Grip and pinch strength norms were collected following the American Society of Hand Therapy protocol. The norms from these working adults were calculated with descriptive statistics for males and females in two age classifications: ages 20 to 49 and ages 50 to 62 years. Standard Errors (SE are better than the 1985 norms for both males and females ages 20 to 49 years. SEs are higher than the ages 20 to 49 years’ norms for the ages 50 to 62 years age categories in both males and females. These norms offer a point of comparison for clinicians to use for clients in Michigan who are ages 20 to 62 years and who have a goal to improve their grip strength. Clients’ grip and pinch strength could be compared to their age level or gender norms using the comparison for one standard deviation above, below, or at the means.

  15. The Psychological Self as Actor, Agent, and Author.

    Science.gov (United States)

    McAdams, Dan P

    2013-05-01

    The psychological self may be construed as a reflexive arrangement of the subjective "I" and the constructed "Me," evolving and expanding over the human life course. The psychological self begins life as a social actor, construed in terms of performance traits and social roles. By the end of childhood, the self has become a motivated agent, too, as personal goals, motives, values, and envisioned projects for the future become central features of how the I conceives of the Me. A third layer of selfhood begins to form in the adolescent and emerging adulthood years, when the self as autobiographical author aims to construct a story of the Me, to provide adult life with broad purpose and a dynamic sense of temporal continuity. An integrative theory that envisions the psychological self as a developing I-Me configuration of actor, agent, and author helps to synthesize a wide range of conceptions and findings on the self from social, personality, cognitive, cultural, and developmental psychology and from sociology and other social sciences. The actor-agent-author framework also sheds new light on studies of self-regulation, self-esteem, self-continuity, and the relationship between self and culture. © The Author(s) 2013.

    Full Text Available The article argues for the universal character of human rights. It is demonstrated that they are not of specific value of Western culture but are a universal norm. This norm is valid not only for political practices but, first of all, for the morality and practice of argumentation. Human rights are strictly correlated with Kantian Categorical Imperative and can be substantiated by means of transcendental­pragmatic argument (K.­O. Apel. The difference between values and norms are also considered. It is demonstrated that values are always subjective and arbitrary meanwhile final justification is possible for norms.

  18. Feasibility of re-melting NORM-contaminated scrap metal

    Energy Technology Data Exchange (ETDEWEB)

    Winters, S. J.; Smith, K. P.

    1999-10-26

    Naturally occurring radioactive materials (NORM) sometimes accumulate inside pieces of equipment associated with oil and gas production and processing activities. Typically, the NORM accumulates when radium that is present in solution in produced water precipitates out in scale and sludge deposits. Scrap equipment containing residual quantities of these NORM-bearing scales and sludges can present a waste management problem if the radium concentrations exceed regulatory limits or activate the alarms on radiation screening devices installed at most scrap metal recycling facilities. Although NORM-contaminated scrap metal currently is not disposed of by re-melting, this form of recycling could present a viable disposition option for this waste stream. Studies indicate that re-melting NORM-contaminated scrap metal is a viable recycling option from a risk-based perspective. However, a myriad of economic, regulatory, and policy issues have caused the recyclers to turn away virtually all radioactive scrap metal. Until these issues can be resolved, re-melting of the petroleum industry's NORM-impacted scrap metal is unlikely to be a widespread practice. This paper summarizes the issues associated with re-melting radioactive scrap so that the petroleum industry and its regulators will understand the obstacles. This paper was prepared as part of a report being prepared by the Interstate Oil and Gas Compact Commission's NORM Subcommittee.

    We study branching extremals of length functionals on normed spaces. This is a natural generalization of the Steiner problem in normed spaces. We obtain criteria for a network to be extremal under deformations that preserve the topology of networks as well as under deformations with splitting. We discuss the connection between locally shortest networks and extremal networks. In the important particular case of the Manhattan plane, we get a criterion for a locally shortest network to be extremal

  1. Variation in reaction norms: Statistical considerations and biological interpretation.

    Morrissey, Michael B; Liefting, Maartje

    2016-09-01

    Analysis of reaction norms, the functions by which the phenotype produced by a given genotype depends on the environment, is critical to studying many aspects of phenotypic evolution. Different techniques are available for quantifying different aspects of reaction norm variation. We examine what biological inferences can be drawn from some of the more readily applicable analyses for studying reaction norms. We adopt a strongly biologically motivated view, but draw on statistical theory to highlight strengths and drawbacks of different techniques. In particular, consideration of some formal statistical theory leads to revision of some recently, and forcefully, advocated opinions on reaction norm analysis. We clarify what simple analysis of the slope between mean phenotype in two environments can tell us about reaction norms, explore the conditions under which polynomial regression can provide robust inferences about reaction norm shape, and explore how different existing approaches may be used to draw inferences about variation in reaction norm shape. We show how mixed model-based approaches can provide more robust inferences than more commonly used multistep statistical approaches, and derive new metrics of the relative importance of variation in reaction norm intercepts, slopes, and curvatures. © 2016 The Author(s).

    , the final quantified data of each social norm showed highly positive correlations with their content value rather than their implementation value, which implied the final value of social norms are mainly affected by the content of social norms. And the implementation of social norms had reached a relatively high degree compare to their theoretical maxvalue (from 71.29% to 80.25%) because of the compelling force of themselves, while the content value of social norms is so weak (from 16.69% to 30.62%) that urgently need to be improved. Third, the method can be extended to quantify the social norms of other ecosystems and further contributed to our understanding of the Coupled Human and Natural Systems and sustainability research.;

  4. Regulatory and management approaches to NORM residues in Malaysia

    Omar, M.; Teng, I.L.

    2006-01-01

    Naturally Occurring Radioactive Material (NORM) processing industries in Malaysia include oil and gas production and mineral processing plants. These industries are controlled by the Atomic Energy Licensing Board of Malaysia (AELB) through the enforcement of the Atomic Energy Licensing Act 1984 (Act 304). Related regulations have been developed in order to ensure the safety of workers and members of the public. However, more regulations are necessary for the safe handling of NORM. NORM processing generates various types of NORM residues that require proper management. As for low-level NORM residues, landfill disposal can be exempted from regulatory control if the Radiological Impact Assessment (RIA) shows that the additional dose to the members of the public is below the limit set by the authority. This paper outlines the regulatory and management approaches to NORM residues in Malaysia. (author)

    2015-01-01

    Performing a task alone or together with another agent can produce different outcomes. The current study used event-related functional magnetic resonance imaging (fMRI) to investigate the neural underpinnings when participants performed a Go/Nogo task alone or complementarily with another co-actor (unseen), whom was believed to be another human or a computer. During both complementary tasks, reaction time data suggested that participants integrated the potential action of their co-actor in their own action planning. Compared to the single-actor task, increased parietal and precentral activity during complementary tasks as shown in the fMRI data further suggested representation of the co-actor's response. The superior frontal gyrus of the medial prefrontal cortex was differentially activated in the human co-actor condition compared to the computer co-actor condition. The medial prefrontal cortex, involved thinking about the beliefs and intentions of other people, possibly reflects a social-cognitive aspect or self-other discrimination during the joint task when believing a biological co-actor is present. Our results suggest that action co-representation can occur even offline with any agent type given a priori information that they are co-acting; however, additional regions are recruited when participants believe they are task-sharing with another human.

    International awareness of NORM as a potential source of radiation risk to workers, members of the public and the environment has increased significantly in recent years. NORM guidelines were originally developed for radiation management in NORM industries. However, the guidelines have been often consulted by many other industries not commonly considered as an NORM industry. In addition, with the increased awareness of NORM issues, more and more people have tried to apply NORM guidelines in many other situations related to NORM in the environment. The broad use of NORM guidelines out of the original scope has demonstrated the needs to revise the guidelines for practical use. These needs are discussed in the article. (authors)

    There has been limited research examining the association between mental health symptoms, perceived peer alcohol norms, and alcohol use and consequences among samples of adolescents. The current study used a sample of 193 at-risk youths with a first-time alcohol and/or other drug offense in the California Teen Court system to explore the moderating role of perceived peer alcohol norms on the association between mental health symptoms and drinking outcomes. Measures of drinking, consequences, mental health symptoms, and perceived peer alcohol norms were taken at baseline, with measures of drinking and consequences assessed again 6 months later. Regression analyses examined the association of perceived norms and mental health symptoms with concurrent and future drinking and consequences. We found that higher perceived drinking peer norms were associated with heavy drinking behavior at baseline and with negative alcohol consequences both at baseline and 6 months later. Also, perceived drinking norms moderated the association between mental health symptoms and alcohol-related consequences such that better mental health was related to increased risk for alcohol-related consequences both concurrently and 6 months later among those with higher baseline perceptions of peer drinking norms. Findings demonstrate the value of norms-based interventions, especially among adolescents with few mental health problems who are at risk for heavy drinking.

    concrete real-investment situations? 3) How do the market actors justify real-investments in production capacity? Building on twenty-five in-depth interviews, and two extensive case studies, the study shows that the stationary electricity industry is characterized by a technical norm-system, which contains institutionalized logics, and norms of rationality. The act of construing and interpreting is a question of different market actors' attitudes towards the technical norm-system, and the organizational role-definition. In concrete real-investment situations, the market actors must conduct their actions in relation to conflicting norms of rationality. Hence, the market actors justification of real-investments in production capacity is a question of their attitudes towards normative institutions and their ability to predict the future. The study concludes that capacity investments in the deregulated electricity market are not caused by market actors' perceptions concerning profitability per se. Indeed, construing of market prices are important, but the undertaking of capacity investments should rather be described as a result of acts of construing and translating political signals, and the will of exercising power. In order to make possible the undertaking of capacity investments, the individual actor is engaged in activities of stabilizing its internal conditions of production as well as its political environment

  13. Three-dimensional total variation norm for SPECT reconstruction

    International Nuclear Information System (INIS)

    Persson, Mikael; Bone, Dianna; Elmqvist, H.

    2001-01-01

    The total variation (TV) norm has been described in literature as a method for reducing noise in two-dimensional (2D) images. At the same time, the TV-norm is very good at recovering edges in images, without introducing ringing or edge artefacts. It has also been proposed as a 2D regularisation function in Bayesian reconstruction, implemented in an expectation maximisation (EM) algorithm, and called TV-EM. The TV-EM was developed for 2D SPECT imaging, and the algorithm is capable of smoothing noise while maintaining edges without introducing artefacts. We have extended the TV-norm to take into account the third spatial dimension, and developed an iterative EM algorithm based on the three-dimensional (3D) TV-norm, which we call TV3D-EM. This takes into account the correlation between transaxial sections in SPECT, due to system resolution. We have compared the 2D and 3D algorithms using reconstructed images from simulated projection data. Phantoms used were a homogeneous sphere, and a 3D head phantom based on the Shepp-Logan phantom. The TV3D-EM algorithm yielded somewhat lower noise levels than TV-EM. The noise in the TV3D-EM had similar correlation in transaxial and longitudinal sections, which was not the case for TV-EM, or any 2D reconstruction method. In particular, longitudinal sections from TV3D-EM were perceived as less noisy when compared to TV-EM. The use of 3D reconstruction should also be advantageous if compensation for distant dependent collimator blurring is incorporated in the iterative algorithm

    2018-01-01

    Children from the age of 3years understand social norms as such and enforce these norms in interactions with others. Differences in parental and institutional education across cultures make it likely that children receive divergent information about how to act in cases of norm violations. In the current study, we investigated whether cultural values are associated with the ways in which children react to norm violations. We tested 80 bicultural 3-year-olds with a norm enforcement paradigm and analyzed their reactions to norm violations. The reactions were correlated to the children's parental cultural values using the Global Leadership and Organizational Behavior Effectiveness (GLOBE) scales, and these results show that parental culture was associated with children's reactions to norm violations. The three strongest correlations were found for institutional collectivism, performance orientation, and assertiveness. Copyright © 2017 Elsevier Inc. All rights reserved.

  16. [Cleanliness Norms 1964-1975].

    1976-01-01

    In 1964 the Institut für Demoskopie Allensbach made a first survey taking stock of norms concerning cleanliness in the Federal Republic of Germany. At that time, 78% of respondents thought that the vogue among young people of cultivating an unkempt look was past or on the wane (Table 1.). Today we know that this fashion was an indicator of more serious desires for change in many different areas like politics, sexual morality, education and that its high point was still to come. In the fall of 1975 a second survey, modelled on the one of 1964, was conducted. Again, it concentrated on norms, not on behavior. As expected, norms have changed over this period but not in a one-directional or simple manner. In general, people are much more large-minded about children's looks: neat, clean school-dress, properly combed hair, clean shoes, all this and also holding their things in order has become less important in 1975 (Table 2). To carry a clean handkerchief is becoming oldfashioned (Table 3). On the other hand, principles of bringing-up children have not loosened concerning personal hygiene - brushing ones teeth, washing hands, feet, and neck, clean fingernails (Table 4). On one item related to protection of the environment, namely throwing around waste paper, standards have even become more strict (Table 5). With regard to school-leavers, norms of personal hygiene have generally become more strict (Table 6). As living standards have gone up and the number of full bathrooms has risen from 42% to 75% of households, norms of personal hygiene have also increased: one warm bath a week seemed enough to 56% of adults in 1964, but to only 32% in 1975 (Table 7). Also standards for changing underwear have changed a lot: in 1964 only 12% of respondents said "every day", in 1975 48% said so (Table 8). Even more stringent norms are applied to young women (Tables 9/10). For comparison: 1964 there were automatic washing machines in 16%, 1975 in 79% of households. Answers to questions

    This study aimed to develop and validate an online instrument to: (1) identify common alcohol-related social influences, norms and beliefs among adolescents; (2) clarify the process and pathways through which proalcohol norms are transmitted to adolescents; (3) describe the characteristics of social connections that contribute to the transmission of alcohol norms; and (4) identify the influence of alcohol marketing on adolescent norm development. The online Youth Alcohol Norms Survey (YANS) was administered in secondary schools in Western Australia PARTICIPANTS: Using a 2-week test-retest format, the YANS was administered to secondary school students (n=481, age=13-17 years, female 309, 64.2%). The development of the YANS was guided by social cognitive theory and comprised a systematic multistage process including evaluation of content and face validity. A 2-week test-retest format was employed. Exploratory factor analysis was conducted to determine the underlying factor structure of the instrument. Test-retest reliability was examined using intraclass correlation coefficient (ICC) and Cohen's kappa. A five-factor structure with meaningful components and robust factorial loads was identified, and the five factors were labelled as 'individual attitudes and beliefs', 'peer and community identity', 'sibling influences', 'school and community connectedness' and 'injunctive norms', respectively. The instrument demonstrated stability across the test-retest procedure (ICC=0.68-0.88, Cohen's kappa coefficient=0.69) for most variables. The results support the reliability and factorial validity of this instrument. The YANS presents a promising tool, which enables comprehensive assessment of reciprocal individual, behavioural and environmental factors that influence alcohol-related norms among adolescents. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Full Text Available The objective of the study was informal social norms of urban culture. The paper contains the detailed description of the experimental situation and the main steps of the field research, focused on the observance of informal social norms in the sphere of urban coloristics. The experiment was conducted in three districts of Smolensk (Russia – Leninskiy, Zadneprovskiy and Promyshlennyy. Particular attention was paid to the analysis of the results of the field research, including evaluation of reaction of participants (residents of multi-storied houses, breakers of informal norms of urban coloristics (experimenters and casual experiment witnesses (neighbors and passersby. In addition, the accuracy of results “forecasting”, done before the beginning of the experiment, is analyzed. The research was conducted using the methodology of breaking experiment that is one of the most provocative ways of studying informal norms in sociology and social psychology. The experiment allowed to draw a number of important conclusions. It showed that urban coloristics is regulated by strict informal norms, that are not noticed by citizens until a violation occurs. The power of informal norms is significantly underestimated by citizens, and their break causes a negative reaction and protest. The most important contribution to the study of informal norms of urban culture was the comparison of the reaction degree by men and women, by the residents of different districts (central, residential or blue-collar neighborhoods, by different age groups.

    2001-01-01

    The Nuclear Regulatory Authority (NRA), through its norm, establishes requirements in the matter of safeguards that allow him to control the fulfillment of the objectives established at national level and the international commitments that the Argentine Republic has assumed in the scope of Nuclear Non-proliferation. The measures of fortification of the safeguards proposed by the International Atomic Energy Agency (IAEA), will imply new obligations for the country and consequently it will require the update of the effective norm in the matter. The objective of this work is to describe the reach of the update of the norm in the matter of safeguards and their relation with some procedures of application in the scope of the radiological protection and the nuclear security

    2010-07-01

    Full Text Available Confronting with numerous problems related to moral judgment, the responsibility and irresponsibility in what concerns the vast domain of communication, we are interested in forming a correct and complete vision that crosses the judicial and deontological domain of the profession. The deontological norms are meant to guarantee, by their freely consented acceptance, the good fulfillment of the mission of the journalists, recognized as being indispensable for the god functioning of any human society. The laws do not expressly refer to the deontological norms, but these norms exist according to the law order and are necessary for its guarantee in this social context, which is chaotic from the point of view of the legislation in communication. The aspects analyzed here aremeant to indicate the manner in which passing from deontological norm to the judicial norm creates an external constraint for the communicator which brings more responsibility in view of avoiding the journalistic conflicts.

    Annual deforestation rates in the Brazilian Amazon fell by 77% between 2004 and 2011, yet have stabilized since 2009 at 5,000-7,000 km(2). We provide the first submunicipality assessment, to our knowledge, of actor-specific contributions to the deforestation slowdown by linking agricultural census and remote-sensing data on deforestation and forest degradation. Almost half (36,158 km(2)) of the deforestation between 2004 and 2011 occurred in areas dominated by larger properties (>500 ha), whereas only 12% (9,720 km(2)) occurred in areas dominated by smallholder properties (deforestation rates fell during this period by 68-85% for all actors, the contribution of the largest landholders (>2,500 ha) to annual deforestation decreased over time (63% decrease between 2005 and 2011), whereas that of smallholders went up by a similar amount (69%) during the same period. In addition, the deforestation share attributable to remote areas increased by 88% between 2009 and 2011. These observations are consistent across the Brazilian Amazon, regardless of geographical differences in actor dominance or socioenvironmental context. Our findings suggest that deforestation policies to date, which have been particularly focused on command and control measures on larger properties in deforestation hotspots, may be increasingly limited in their effectiveness and fail to address all actors equally. Further reductions in deforestation are likely to be increasingly costly and require actor-tailored approaches, including better monitoring to detect small-scale deforestation and a shift toward more incentive-based conservation policies.

    The assumed characteristics of individuals in the adult entertainment industry have been used to advocate positions for and against pornography. Although prior studies have investigated perceptions of porn actors, no data on the actual characteristics of this group exist. The present study compared the self-reports of 105 male and 177 female porn actors to the perceptions of 399 college students on childhood sexual abuse (CSA), self-esteem, work and non-work sexual behaviors, and safe sex issues. College students were asked to identify the characteristics associated with either a male or female porn star. College students provided underestimates for both female and male porn actors on self-esteem, age of first intercourse, lifetime number of partners outside of work, ideal experience in a romantic partner, concerns regarding sexually transmitted diseases (STDs), enjoyment of sex, and condom use during a first time sexual encounter, but overestimated earnings. Additional differences among male porn stars included an underestimate of the number of partners at work. For female porn stars, college students underestimated their enjoyment of work, the probability of catching an STD, and having unprotected sex. Although there were no significant differences on perceived rates of childhood abuse of porn actors, the incidence of CSA among the porn actor participants were within the ranges of the general population. The majority of college student stereotypes were not supported regarding the perceptions of porn actors. These findings were discussed within the context of attributing unfounded characteristics of individuals to an entire industry.

  5. Approach to NORM/TENORM Problem based on Radiation Protection Principle

    International Nuclear Information System (INIS)

    Kosako, T.; Sugiura, N.

    2004-01-01

    Naturally Occurring Radioactive Material (NORM) and Technologically Enhanced Naturally Occurring Radioactive Material (TENORM) are recent discussion issues in radiation protection. Relating materials are phosphate fertilizer, rare earth material, oil and gas, coal, metal ore, cement, ceramics, mineral sand, titanium pigment, building materials etc. These related industries, workers and public should be protected from radiations by including radioactive materials like uranium, thorium, radium etc. In this article, typical states of these materials and management are briefly reviewed and radiation protection principles how to consider NORM/TENORM based on ICRP recommendations and IAEA standards are discussed. Originally, the natural materials are excluded for its un-amenability of control. But under several conditions, an intervention concept should be applied and some consumer products are to be controlled based on a practice concept. The regulatory management is examined through a classification of NORM/TENORM and development of concepts; practice and intervention, exclusion and exemption, optimization of protection, etc. The optimization of protection is one of the most important discussion points. The origin of radioisotopes is natural. Therefore, the criteria or standard should be different from that of artificial source. Too strict regulation will cause much social and economical confusion. The harmonization of radiation protection system on NORM/TENORM in FNCA (Forum for Nuclear Cooperation in Asia) countries was also tried by information exchange and intercomparison. (Author)

  6. Conceptualising the public health role of actors operating outside of formal health systems: The case of social enterprise.

    Science.gov (United States)

    Roy, Michael J; Baker, Rachel; Kerr, Susan

    2017-01-01

    This paper focuses on the role of actors that operate outside formal health systems, but nevertheless have a vital, if often under-recognised, role in supporting public health. The specific example used is the 'social enterprise', an organisation that seeks, through trading, to maximise social returns, rather than the distribution of profits to shareholders or owners. In this paper we advance empirical and theoretical understanding of the causal pathways at work in social enterprises, by considering them as a particularly complex form of public health 'intervention'. Data were generated through qualitative, in depth, semi-structured interviews and a focus group discussion, with a purposive, maximum variation sample of social enterprise practitioners (n = 13) in an urban setting in the west of Scotland. A method of analysis inspired by critical realism - Causation Coding - enabled the identification of a range of explanatory mechanisms and potential pathways of causation between engagement in social enterprise-led activity and various outcomes, which have been grouped into physical health, mental health and social determinants. The findings then informed the construction of an empirically-informed conceptual model to act as a platform upon which to develop a future research agenda. The results of this work are considered to not only encourage a broader and more imaginative consideration of what actually constitutes a public health intervention, but also reinforces arguments that actors within the Third Sector have an important role to play in addressing contemporary and future public health challenges.

    The theories of professions, public service motivation, and economic incentives explain the behaviour of the producers of publicly financed services differently. They emphasize professional norms, sector, and economic incentives, respectively. The few existing attempts to integrate these theories...... have, however, indicated that these factors interact. Using interviews, surveys and registers, the paper investigated how professional norms, economic incentives and sector affected the behaviour of Danish dentists and physicians. It was found that when strong professional norms existed, economic...... incentives were unimportant for both public and private employees. In contrast, when no firm professional norm applied, economic incentives affected behaviour. Controlling for different economic incentives, sector does not seem to affect the behaviour much. The results imply that the economic...

  8. The legislative actor in the Nobel era: Quo Vadis EU?

    2013-05-01

    Full Text Available The idea of a political union, as well as an economic union of Europe, beyond free circulation of persons, goods and services, has always been included in the ideals of the building of Europe. However, its de jure formalization only occurs on November 1, 1993, when the Treaty of Maastricht is in force and a new political and strategic actor is in place: the European Union (EU. Since then, literature has "defined" the European Union in order to clearly establish what this UPO - Unidentified Political Object (an expression by Jacques Delors in the 1990s - is or what it can be. One of the ideas which has been a focus of discussion is that of "legislative actor" (Manners, 2001; 2002, which claims that the European Union has progressed towards normativity, both internally as well as externally, to its close neighbors and its relations with the rest of the world. This paper aims to contribute to the discussion on Europe's quality or condition to impose rules. We will begin by systematizing a series of achievements which, according to Manners, lead to the triangle democracy, Human Rights and good governance in the signing of the Treaty of Lisbon on December 13, 2007 and its entering in full force on December 1, 2009. However, this paper does not disregard the fact that the concept "legislative actor" has been (reworked and perfected by its author and other scholars due to criticism and empirical studies and has thus been altered, enhanced and argued against. Therefore, some concepts will be studied whose arguments will allow us to question the internal and external dimension of the actor European Union. We will also explore the symbolic power of the Union in the development of tools and capacity to be acknowledged as an actor able to face current threats and challenges but whose profile may not be different from other actors in international relations. Finally, we will discuss the impact of the EU having been awarded the Nobel Peace Prize in 2012 on

  10. Peer punishment promotes enforcement of bad social norms.

    2017-09-20

    Social norms are an important element in explaining how humans achieve very high levels of cooperative activity. It is widely observed that, when norms can be enforced by peer punishment, groups are able to resolve social dilemmas in prosocial, cooperative ways. Here we show that punishment can also encourage participation in destructive behaviours that are harmful to group welfare, and that this phenomenon is mediated by a social norm. In a variation of a public goods game, in which the return to investment is negative for both group and individual, we find that the opportunity to punish led to higher levels of contribution, thereby harming collective payoffs. A second experiment confirmed that, independently of whether punishment is available, a majority of subjects regard the efficient behaviour of non-contribution as socially inappropriate. The results show that simply providing a punishment opportunity does not guarantee that punishment will be used for socially beneficial ends, because the social norms that influence punishment behaviour may themselves be destructive.Punishment by peers can enforce social norms, such as contributing to a public good. Here, Abbink and colleagues show that individuals will enforce norms even when contributions reduce the net benefit of the group, resulting in the maintenance of wasteful contributions.

  14. Full waveform inversion using envelope-based global correlation norm

    Science.gov (United States)

    Oh, Ju-Won; Alkhalifah, Tariq

    2018-05-01

    To increase the feasibility of full waveform inversion on real data, we suggest a new objective function, which is defined as the global correlation of the envelopes of modelled and observed data. The envelope-based global correlation norm has the advantage of the envelope inversion that generates artificial low-frequency information, which provides the possibility to recover long-wavelength structure in an early stage. In addition, the envelope-based global correlation norm maintains the advantage of the global correlation norm, which reduces the sensitivity of the misfit to amplitude errors so that the performance of inversion on real data can be enhanced when the exact source wavelet is not available and more complex physics are ignored. Through the synthetic example for 2-D SEG/EAGE overthrust model with inaccurate source wavelet, we compare the performance of four different approaches, which are the least-squares waveform inversion, least-squares envelope inversion, global correlation norm and envelope-based global correlation norm. Finally, we apply the envelope-based global correlation norm on the 3-D Ocean Bottom Cable (OBC) data from the North Sea. The envelope-based global correlation norm captures the strong reflections from the high-velocity caprock and generates artificial low-frequency reflection energy that helps us recover long-wavelength structure of the model domain in the early stages. From this long-wavelength model, the conventional global correlation norm is sequentially applied to invert for higher-resolution features of the model.

  15. On the pseudo-norm in some PT-symmetric potentials

    International Nuclear Information System (INIS)

    Levai, G.

    2005-01-01

    Complete text of publication follows. PT-symmetric quantum mechanical systems possess non-hermitian Hamiltonian, still they have some characteristics similar to hermitian problems. The most notable of these is their discrete energy spectrum, which can be partly or completely real. These systems are invariant under the simultaneous action of the P space and T time inversion operations. Perhaps the simplest PT-symmetric Hamiltonian contains a one-dimensional Schroedinger operator with a complex potential satisfying the V*(-x) = V (x) relation. Another typical feature PT-symmetric systems have in common with hermitian problems is that their basis states form an orthogonal set provided that the inner product is redefined as (ψ φ)PT ≡ (ψ Pφ). However, the norm defined by this inner product, the pseudo-norm turned out to possess indefinite sign, and this raised the question of the probabilistic interpretation of PT-symmetric systems. This problem was later put into a more general context when it was found that PT symmetry is a special case of pseudo-hermiticity, and this explains most of the peculiar features of PT-symmetric systems. There have been several attempts to link PT-symmetric, and in general, pseudo- hermitian systems with equivalent hermitian ones, and the sign of the pseudo-norm was found to play an important role in this respect. It is thus essential to evaluate the pseudo- norm for various potentials, especially considering the fact that there are some inconsistencies in the available results. Numerical studies indicated that the sign of the pseudo-norm typically alternates according to the n principal quantum number as (-1) n , and this was later proven for a class of potentials that are written in a polynomial form of ix. However, some potentials of other type did not fit into this line: this was the case for the Scarf II potential, the most well-known exactly solvable PT-symmetric potential. In contrast with the other examples, this potential is

  16. Conceptual Models for Ecosystem Management through the Participation of Local Social Actors: the Río Cruces Wetland Conflict

    Directory of Open Access Journals (Sweden)

    Luisa E. Delgado

    2009-06-01

    Full Text Available In 2004, the emigration and death of black-necked swans (Cygnus melancoryphus from the Río Cruces wetland (Valdivia, Chile triggered one of the largest ecosocial conflicts in Chilean history. The main local social actors of this still unsolved conflict are the Chilean government, a pulp-mill company, and a local nongovernmental organization. The central issues of the conflict are disagreement over the reason for the swans' migration, the need to restore the black-necked swan population in the wetland, and the relationship between economic development and wetland conservation. We applied a physical, ecological, and social system approach to generate conceptual or qualitative ecosystem models representing the perceptions of all social actors. Our results showed that each actor group perceived the ecosystem in a different and, in some cases, divergent way. Furthermore, all of them carried only partial representations of the wetland and the conflict. We linked all the models to generate an integrated view of the Río Cruces wetland ecosystem. We propose that this approach can be replicated as a tool for generating synthetic, integrated conceptual models of ecosystems, even in the presence of strong divergence and a lack of consensus among social actors.

    2018-06-01

    This paper analyzes the actors in the climate change arena and their influence in directing Mexico toward policies that decrease greenhouse gas emissions, such as the carbon tax and climate change law. The network analysis of the agreement of these laws and public policies in Mexico is a lesson for any country that is in the process of designing and adopting environmental laws. The research is performed using a network analysis that is derived from interviews with various main actors and a discourse analysis of the media. Results show that actors do not coordinate their efforts-they meet frequently but in different inter-ministerial commissions-and do not enforce the same policies. The actors in the industry have formed strong coalitions against the carbon tax and the General Law on Climate Change, whereas international institutions have formed coalitions that support these policies and laws.

    Using a regional measure of gender norms from the General Social Surveys together with marital histories from the Panel Study of Income Dynamics, this study explored how gender norms were associated with women's marriage dynamics between 1968 and 2012. Results suggested that a higher prevalence of egalitarian gender norms predicted a decline in marriage formation. This decline was, however, only true for women without a college degree. For college-educated women, the association between gender norms and marriage formation became positive when gender egalitarianism prevailed. The findings also revealed an inverted U-shaped relationship between gender norms and divorce: an initial increase in divorce was observed when gender norms were predominantly traditional. The association, however, reversed as gender norms became egalitarian. No differences by education were found for divorce. The findings partially support the gender revolution framework but also highlight greater barriers to marriage for low-educated women as societies embrace gender equality.

A two-stage design to i) compare the perceived importance of normative influences vs cost and health on dietary choices, and ii) test the prediction that providing information on social norms will increase intended fruit and vegetable consumption in an experimental study. Home-based interviews (N=1083; 46% men, 54% women) were carried out as part of the Office for National Statistics Omnibus Survey in November 2008. The public's perception of the importance of social norms was lower (M=2.1) than the perceived importance of cost (M=2.7) or health (M=3.4) (all p'scost information; none of the interventions affected women's intentions. People have little awareness of the influence of social norms but normative information can have a demonstrable impact on dietary intentions. Health promotion might profit from emphasising how many people are attempting to adopt healthy lifestyles rather than how many have poor diets.

    Objective Analyzing the relationship between socio-demographic characteristics of youth from the Landless Rural Workers' Movement in Brazil (MST) regarding the prevalence ratio being in accordance with gender norms. Method A cross-sectional study conducted during a Journey of Agroecology carried out in the State of Paraná with young people (15 to 29 years) of both genders. Data collection was conducted through questionnaires. Data analysis compared variables regarding gender norms with sociodemographic variables, and a Prevalence Ratio (PR) was calculated with a confidence interval (CI) set at 95% in order to determine this relationship. Results The study sample was comprised of 147 young people. A higher prevalence was found in accordance with gender norms (PR with CI at 95%) among women compared to men, and that sociodemographic characteristics (lower education level, those living in occupation camps, who do not have white skin and with religious belief) were social indicators for such positioning among both genders. Conclusion The byproduct of a patriarchal gender system has led more young girls to internalization and a reaffirmation of gender norms, highlighting an important field for social nursing practices in order to contribute to the transformation of this reality.

Besides being objects of study and monitoring such materials can be used as raw material or as by-products or waste of industrial activities. Oil and gas, mining and water treatment are examples of facilities that can handle NORM. In such cases, their concentration at significant levels from the perspective of environmental and occupational radiation protection may occur. This study aims to evaluate the presence of the natural radioactive 238 U and 232 Th series in the treatment of city water elements Poços de Caldas - MG (water, materials and waste). The study can serve as an indication of the necessity of a more detailed review in the locally and in the country on this radiological issue. (authors)

    1996-01-01

    A class of models is proposed for longitudinal network data. These models are along the lines of methodological individualism: actors use heuristics to try to achieve their individual goals, subject to constraints. The current network structure is among these constraints. The models are continuous

    This paper evaluates the levels of radioactivity (dose rates of gamma radiation) in the elements of the production unit FPSO (floating production, storage and offloading) process that show the presence of fouling and / or radioactive waste and its evolution over time, comparing with previous reviews. The radioactivity is detected due to the presence of NORM - Naturally Occurring Radioactive Material, consisting predominantly of BaSO4, containing radio, radioactive natural element, which presents itself as the Ra-226 and Ra-228 isotopes. The detection of radioactivity in equipment/piping indicates the presence of scaling and/or sludge containing naturally radioactive material (NORM), but the absence of radioactivity does not exclude the presence of scale or sludge, as this may consist of non-radioactive material, as CaCO3. Gamma radiation has the property to pass through the construction element (steel) of the lines and equipment, allowing detection of radioactive material within them without the need of opening. This monitoring was implemented due to the history of radioactive inlays in the Espirito Santo basin. These data contribute to decision-making on strategy of dosage of anti-fouling applied in the production system, enable the classification of areas according to the norm CNEN-NN-3.01, as well as guide to the occupational safety and hygiene procedures during interventions (openings, entrances and cleaning) on the elements of process.

  8. l1- and l2-Norm Joint Regularization Based Sparse Signal Reconstruction Scheme

    2016-01-01

    Full Text Available Many problems in signal processing and statistical inference involve finding sparse solution to some underdetermined linear system of equations. This is also the application condition of compressive sensing (CS which can find the sparse solution from the measurements far less than the original signal. In this paper, we propose l1- and l2-norm joint regularization based reconstruction framework to approach the original l0-norm based sparseness-inducing constrained sparse signal reconstruction problem. Firstly, it is shown that, by employing the simple conjugate gradient algorithm, the new formulation provides an effective framework to deduce the solution as the original sparse signal reconstruction problem with l0-norm regularization item. Secondly, the upper reconstruction error limit is presented for the proposed sparse signal reconstruction framework, and it is unveiled that a smaller reconstruction error than l1-norm relaxation approaches can be realized by using the proposed scheme in most cases. Finally, simulation results are presented to validate the proposed sparse signal reconstruction approach.

    Heavy drinking is common among students at UK universities. US students overestimate how much their peers drink and correcting this through the use of social norm messages may promote responsible drinking. We tested whether there is an association between perceived campus drinking norms and usual drinking behavior in UK university students and whether norm messages about responsible drinking correct normative misperceptions and increase students' intentions to drink responsibly. 1,020 UK university students took part in an online study. Participants were exposed to one of five message types: a descriptive norm, an injunctive norm, a descriptive and injunctive norm, or one of two control messages. Message credibility was assessed. Afterwards participants completed measures of intentions to drink responsibly and we measured usual drinking habits and perceptions of peer drinking. Perceptions of peer drinking were associated modestly with usual drinking behavior, whereby participants who believed other students drank responsibly also drank responsibly. Norm messages changed normative perceptions, but not in the target population of participants who underestimated responsible drinking in their peers at baseline. Norm messages did not increase intentions to drink responsibly and although based on accurate data, norm messages were not seen as credible. In this UK based study, although perceived social norms about peer drinking were associated with individual differences in drinking habits, campus wide norm messages about responsible drinking did not affect students' intentions to drink more responsibly. More research is required to determine if this approach can be applied to UK settings.

Therefore, the CNEN is responsible for any radioactive waste disposal in the country. Oil Naturally Occurring Radioactive Materials (Oil NORM) in this paper refers to waste coming from oil exploration. Oil NORM has called much attention during the last decades, mostly because it is not possible to determine its primary source due to the actual absence of regulatory control mechanism.

This fact may encourage non-authorized radioactive material transportation, smuggling and terrorism. The aim of this project is to provide a geochemical signature for each oil NORM waste using its naturally occurring isotopic composition to identify its origin. The here proposed method is a specific geochemical modeling of oil sludge NORM samples which are analyzed for radioisotopes normally present in oil pipes, such as 228 Ac, 214 Bi and 214 Pb. The activity ratios are plotted in scatter diagrams.

The current study used event-related functional magnetic resonance imaging (fMRI to investigate the neural underpinnings when participants performed a Go/Nogo task alone or complementarily with another co-actor (unseen, whom was believed to be another human or a computer.

    2012-10-01

    Research on terror management theory found evidence that people under mortality salience strive to live up to salient cultural norms and values, like egalitarianism, pacifism, or helpfulness. A basic, strongly internalized norm in most human societies is the norm of reciprocity: people should support those who supported them (i.e., positive reciprocity), and people should injure those who injured them (i.e., negative reciprocity), respectively. In an experiment (N = 98; 47 women, 51 men), mortality salience overall significantly increased personal relevance of the norm of reciprocity (M = 4.45, SD = 0.65) compared to a control condition (M = 4.19, SD = 0.59). Specifically, under mortality salience there was higher motivation to punish those who treated them unfavourably (negative norm of reciprocity). Unexpectedly, relevance of the norm of positive reciprocity remained unaffected by mortality salience. Implications and limitations are discussed.

  16. Radiation protection and the naturally occurring radioactive materials (NORM)

    1996-01-01

    There are many industries dealing with naturally occurring radioactive materials (NORM), some of them without knowing that their industrial processes and/or their regular wastes involve radioactivity. However, an increasing number of industries that produce NORM wastes are being sued, wherever there is a legal framework to do so. In particular, NORM wastes produced for a long time by the oil industry became foci of legal battles in the United States and elsewhere. The ripple effect of these judicial battles will influence the decision making processes of NORM wastes producing industries, mostly because of the costs incurred by remedial and preventive actions concerning NORM contamination. The regulation of NORM will occur sooner or later, and such actions may become mandatory. A foreseeable consequence of such regulation is a change in attitude concerning the sources and materials associated with NORM. Among those industries likely to be affected one can mention: niobium; rare earth processing; oil production; phosphate; uranium mining and milling; zircon; water treatment; and waste water treatment. The paper will briefly review data on exempt concentration activities, as suggested by the basic safety standards based on realistic environmental and dosimetric models. These activity concentrations are compared with those found in a number of extractive industries, and may be used to establish derived limits from a pre-established dose limit. (author)

  18. Prosocial norms as a positive youth development construct: a conceptual review.

    Siu, Andrew M H; Shek, Daniel T L; Law, Ben

    2012-01-01

    Prosocial norms like reciprocity, social responsibility, altruism, and volunteerism are ethical standards and beliefs that youth development programs often want to promote. This paper reviews evolutionary, social-cognitive, and developmental theories of prosocial development and analyzes how young people learn and adopt prosocial norms. The paper showed that very few current theories explicitly address the issue of how prosocial norms, in form of feelings of moral obligations, may be challenged by a norm of self-interest and social circumstances when prosocial acts are needed. It is necessary to develop theories which put prosocial norms as a central construct, and a new social cognitive theory of norm activation has the potential to help us understand how prosocial norms may be applied. This paper also highlights how little we know about young people perceiving and receiving prosocial norms and how influential of school policies and peer influence on the prosocial development. Lastly, while training of interpersonal competence (e.g., empathy, moral reasoning, etc.) was commonly used in the youth development, their effectiveness was not systematically evaluated. It will also be interesting to examine how computer and information technology or video games may be used in e-learning of prosocial norms.

  19. Effect of Acting Experience on Emotion Expression and Recognition in Voice: Non-Actors Provide Better Stimuli than Expected.

    Jürgens, Rebecca; Grass, Annika; Drolet, Matthis; Fischer, Julia

    Both in the performative arts and in emotion research, professional actors are assumed to be capable of delivering emotions comparable to spontaneous emotional expressions. This study examines the effects of acting training on vocal emotion depiction and recognition. We predicted that professional actors express emotions in a more realistic fashion than non-professional actors. However, professional acting training may lead to a particular speech pattern; this might account for vocal expressions by actors that are less comparable to authentic samples than the ones by non-professional actors. We compared 80 emotional speech tokens from radio interviews with 80 re-enactments by professional and inexperienced actors, respectively. We analyzed recognition accuracies for emotion and authenticity ratings and compared the acoustic structure of the speech tokens. Both play-acted conditions yielded similar recognition accuracies and possessed more variable pitch contours than the spontaneous recordings. However, professional actors exhibited signs of different articulation patterns compared to non-trained speakers. Our results indicate that for emotion research, emotional expressions by professional actors are not better suited than those from non-actors.

    Full Text Available African Initiated Churches (AICs are not yet recognised as relevant actors of community development interventions. While it has been acknowledged that many of them provide coping mechanisms in adverse environments, support in social transformation and social capital, little information is available on their role as development actors. In this article, we evaluate the potential of AICs as partners of international development agencies for community development. We draw on interviews and focus group discussions with leaders of various AICs conducted in South Africa in February and March 2016. In particular, we examine the churches’ understanding of development, their view on the separation of spiritual and development activities and their priorities. Moreover, we outline the development activities which they are currently engaged in and analyse the structures they have in place to do so. Our findings indicate that AICs are increasingly active in community development and offer various entry points for possible cooperation.

  1. Developmental Eye Movement (DEM Test Norms for Mandarin Chinese-Speaking Chinese Children.

    Directory of Open Access Journals (Sweden)

    Yachun Xie

    Full Text Available The Developmental Eye Movement (DEM test is commonly used as a clinical visual-verbal ocular motor assessment tool to screen and diagnose reading problems at the onset. No established norm exists for using the DEM test with Mandarin Chinese-speaking Chinese children. This study aims to establish the normative values of the DEM test for the Mandarin Chinese-speaking population in China; it also aims to compare the values with three other published norms for English-, Spanish-, and Cantonese-speaking Chinese children. A random stratified sampling method was used to recruit children from eight kindergartens and eight primary schools in the main urban and suburban areas of Nanjing. A total of 1,425 Mandarin Chinese-speaking children aged 5 to 12 years took the DEM test in Mandarin Chinese. A digital recorder was used to record the process. All of the subjects completed a symptomatology survey, and their DEM scores were determined by a trained tester. The scores were computed using the formula in the DEM manual, except that the "vertical scores" were adjusted by taking the vertical errors into consideration. The results were compared with the three other published norms. In our subjects, a general decrease with age was observed for the four eye movement indexes: vertical score, adjusted horizontal score, ratio, and total error. For both the vertical and adjusted horizontal scores, the Mandarin Chinese-speaking children completed the tests much more quickly than the norms for English- and Spanish-speaking children. However, the same group completed the test slightly more slowly than the norms for Cantonese-speaking children. The differences in the means were significant (P0.05; compared with Spanish-speaking children, the scores were statistically significant (P0.05. DEM norms may be affected by differences in language, cultural, and educational systems among various ethnicities. The norms of the DEM test are proposed for use with Mandarin Chinese

  2. Defining and Theorizing Terrorism: A Global Actor-Centered Approach

    Directory of Open Access Journals (Sweden)

    2015-08-01

    Full Text Available Arriving at a consensual definition of the phenomenon of terrorism has been a particularly difficult undertaking. Some definitions are either too specific or too vague, concentrating on some essential “terrorist” aspect of the actions, strategies, or types of non-state organizations that engage in terrorism. In this paper I draw on global approaches from international relations and world systems theories to propose a definition of terrorism that skirts these issues by concentrating on terrorist actors rather than terrorist behavior. I argue that this approach has several advantages, including the dissolution of several empirical and analytical problems produced by more essentialist definitions, and the location of terrorism within a two dimensional continuum of collective-violence phenomena in the international system which discloses important theoretical insights. I proceed to examine the characteristics of terrorism by comparing it with other forms of violence in the international system. I propose that terrorism may be part of the cycles and trends of unrest in the world system, responding to the same broad families of global dynamics as other forms of system-level conflict.

  4. Training on NORM: Increasing awareness, reducing occupational dose

    Hoogstraate, H.; Sonsbeek, R. van

    2002-01-01

    Awareness of a risk is the starting point of protection against it. The best way of creating this awareness is by providing training to the persons that run the risk. This also applies to the risks associated with the presence of Naturally Occurring Radioactive Materials (NORM) in oil and gas production installations. Our experience shows that with relatively little effort, and low cost it is possible to provide training on NORM to operational personnel of oil and gas companies. In this way, a reduction of occupational dose and an increased protection of the environment can be achieved. This applies in particular to the less developed countries, where little regulation is in place. The workers themselves form a group that is motivated and eager to learn about these risks.Training of personnel is a valuable tool to make people more conscious of the risks involved with radiation and to safeguard society, instead of a system of permissions and governmental regulations that often is not functioning properly.

    2017-11-01

    Full Text Available The purpose of this article is to survey a class of normed algebras that share many central features of Banach algebras, save for completeness. The likeness of these algebras to Banach algebras derives from the fact that the geometric series test is valid, whereas the lack of completeness points to the failure of the absolute convergence test for series in the algebra. Our main result is a compendium of conditions that are all equivalent to the validity of the geometric series test for commutative unital normed algebras. Several examples in the final section showcase some incomplete normed algebras for which the geometric series test is valid, and still others for which it is not.

    2016-03-01

    The Cognitive Drug Research (CDR) System is a set of nine computerized tests of attention, information processing, working memory, executive control and episodic memory which was designed for repeated assessments in research projects. The CDR System has been used extensively in clinical trials involving healthy volunteers for over 30 years, and a database of 7751 individuals aged 18-87 years has been accumulated for pre-treatment data from these studies. This database has been analysed, and the relationships between the various scores with factors, including age, gender and years of full-time education, have been identified. These analyses are reported in this paper, along with tables of norms for the various key measures from the core tasks stratified by age and gender. These norms can be used for a variety of purposes, including the determination of eligibility for participation in clinical trials and the everyday relevance of research findings from the system. In addition, these norms provide valuable information on gender differences and the effects of normal ageing on major aspects of human cognitive function. © The Author(s) 2016.

    Actors are widely used in medical education as simulated patients. In this session, the role of actors was extended to 'simulated students' and facilitators in an introductory communication session. After an initial activity with the entire cohort of first-year students, groups of 20 students worked with either an actor or medical teacher in three activities. The activities aimed to raise students' awareness of the range of communication challenges in medical education and practice. After the session, students completed evaluation forms based on their experiences in the session. The results revealed no difference between students who were facilitated by actors or medical teachers in relation to meeting the learning objectives and their ratings of the usefulness of the activities to support learning. The actors who participated in this session were experienced in working with medical students. Their enhanced role provides students with an opportunity to identify with and reflect on the expertise of a lay teacher and to consider extending their definition of a learning opportunity to more informal encounters.

  12. Involving new actors to achieve ART scaling-up: difficulties in an HIV/AIDS counselling and testing centre in Cameroon.

    Yakam, J C Y Tantchou; Gruénais, M-E

    2009-03-01

    The high HIV/AIDS-related mortality among young adults is devastating countries in sub-Saharan Africa. The implementing capacity of the health systems is the main limiting factor of antiretroviral treatment (ART) scaling-up;(1) this capacity depends mainly on the health workforce. Tackling the issue of human resources for health is thus of paramount importance to achieve universal access to ART and for the survival of health systems in time of AIDS. To support such a process, the World Health Organization stresses the importance of task shifting(2) from medical doctors to nurses and from nurses to community health workers. Such task shifting is not easy to achieve but undoubtedly needed. This paper raises issues about the involvement of new actors(3) without precise redefinitions of roles and task-shifting procedures. We take the example of a 'Centre de Prévention et de Dépistage Volontaire du VIH/sida'(4) in one major town of the Far-North province of Cameroon (Central Africa). The study was qualitative. Observations were carried out in the service and in-depth interviews conducted with health workers and actors of Cameroon's National AIDS Control Committee. These interviews were recorded and transcribed. The material was analysed using keywords. KEY RESULT: The involvement of new actors in a context of human resources for health shortage and health system crisis creates confusion and role conflicts, which lead to frustration. It favours the appearance of chinks within which these new actors slip and 'find their way' in the system; it finally raises problems related to their legitimacy and position within the existing hierarchy. KEY POLICY MESSAGE: It is necessary, when involving new staff members (particularly when they do not belong to internationally recognized health professionals such as nurses, doctors and pharmacists), to redefine roles and build precise task-shifting procedures so that everyone may still have a place in the whole system and feel useful.

  13. The radioactivity measurement in the Loire catchment basin. Actors, networks, data inventory

    International Nuclear Information System (INIS)

    2008-01-01

    The objective of this report on the Loire watershed was to broaden at all the nuclear installations of the watershed the method of synthesis made for Saint-Laurent-des-Eaux nuclear power plant, by resting on the whole of actors doing the radioactivity measurements in environment. This report shows that these actors are numerous. The measurement plans implemented have for objective to establish the radiological situation of environment, near or not the nuclear facilities, to detect the abnormal increase of radioactivity, to evaluate the exposure of populations to the ambient radioactivity, or to check the conformity of practices (nuclear activities) and products. This assessment enlightens the lack of a real global strategy in the organisation of the radioactivity measurement at the level of the watershed. The inventory of available data for the Loire watershed allowed to show the diversity of measurements realised. The I.R.S.N. is face to a complex situation of data return in the frame of the implementation of an information system of the national network of radioactivity measurement in environment. (N.C.)

  14. The Social Norms of Suicidal and Self-Harming Behaviours in Scottish Adolescents.

    2017-03-15

    Although the suicidal and self-harming behaviour of individuals is often associated with similar behaviours in people they know, little is known about the impact of perceived social norms on those behaviours. In a range of other behavioural domains (e.g., alcohol consumption, smoking, eating behaviours) perceived social norms have been found to strongly predict individuals' engagement in those behaviours, although discrepancies often exist between perceived and reported norms. Interventions which align perceived norms more closely with reported norms have been effective in reducing damaging behaviours. The current study aimed to explore whether the Social Norms Approach is applicable to suicidal and self-harming behaviours in adolescents. Participants were 456 pupils from five Scottish high-schools (53% female, mean age = 14.98 years), who completed anonymous, cross-sectional surveys examining reported and perceived norms around suicidal and self-harming behaviour. Friedman's ANOVA with post-hoc Wilcoxen signed-ranks tests indicated that proximal groups were perceived as less likely to engage in or be permissive of suicidal and self-harming behaviours than participants' reported themselves, whilst distal groups tended towards being perceived as more likely to do so. Binary logistic regression analyses identified a number of perceived norms associated with reported norms, with close friends' norms positively associated with all outcome variables. The Social Norms Approach may be applicable to suicidal and self-harming behaviour, but associations between perceived and reported norms and predictors of reported norms differ to those found in other behavioural domains. Theoretical and practical implications of the findings are considered.

    Full Text Available Although the suicidal and self-harming behaviour of individuals is often associated with similar behaviours in people they know, little is known about the impact of perceived social norms on those behaviours. In a range of other behavioural domains (e.g., alcohol consumption, smoking, eating behaviours perceived social norms have been found to strongly predict individuals’ engagement in those behaviours, although discrepancies often exist between perceived and reported norms. Interventions which align perceived norms more closely with reported norms have been effective in reducing damaging behaviours. The current study aimed to explore whether the Social Norms Approach is applicable to suicidal and self-harming behaviours in adolescents. Participants were 456 pupils from five Scottish high-schools (53% female, mean age = 14.98 years, who completed anonymous, cross-sectional surveys examining reported and perceived norms around suicidal and self-harming behaviour.

    This article investigates the organizational changes triggered by the implementation of certified management systems (CMS) in Denmark and explores how institutionalized organizational practices change over time. The study shows that improvements in performance were not significant...... in the implementation of CMS, though in most cases its adoption implied organizational changes. The study also shows that the search for external legitimacy was appropriated by various internal organizational actors, other than management. When internal actors share the institutionalized beliefs and norms of the wider...

    Full Text Available Vietnam was one of the first countries to introduce the National REDD+ (Reduced Emissions from Deforestation and Forest Degradation Action Program in 2012. The country has recently revised the Program to aim for a more inclusive 2016–2020 strategy and a vision to 2030. This study explores how Vietnam policy actors view REDD+ policy development and their influence in these processes. The results can contribute to the discussion on how policy actors can effectively influence policy processes in the evolving context of REDD+ and in the types of political arrangements represented in Vietnam. We examined the influence of state and non-state actors on the 2012 National REDD+ Action Program (NRAP processes, and explored factors that may have shaped this influence, using a combination of document analysis and semi-structured interviews with 81 policy actors. It was found that non-state actors in REDD+ are still on the periphery of decision making, occupying “safe” positions, and have not taken either full advantage of their capacities, or of recent significant changes in the contemporary policy environment, to exert stronger influence on policy. We suggest that REDD+ policy processes in Vietnam need to be revitalized with key actors engaging collectively to promote the possibilities of REDD+ within a broader view of social change that reaches beyond the forestry sector.

    1995-01-01

    NORM (Naturally Occurring Radioactive Material) has now been found to be associated with many industrial activities that extends far beyond oil and gas production. There are approximately 59 naturally occurring radionuclides that might end up in a train of NORM contamination, which could impact at least 13 industries. It is appropriate and indeed necessary to examine the geological roots of NORM and its concentration in various industries. Impacted NORM industries and their associated problems are presented. Some plant and environmental managers may not even suspect they have NORM problems, because one cannot ''sense'' NORM without instrumentation, until it might be too late for the health and safety of the effected employees and surrounding community. Others want to ''see no evil, hear no evil or speak any evil'' until they are forced into ''reactive'' environmental management, rather than ''proactive'' management. It has been the experience of many that reactive management is far more costly than proactive management

    Full Text Available In this paper we introduce the notion of canonical partial metric associated to a norm to study geometric properties of normed spaces. In particular, we characterize strict convexity and uniform convexity of normed spaces in terms of the canonical partial metric defined by its norm. We prove that these geometric properties can be considered, in this sense, as topological properties that appear when we compare the natural metric topology of the space with the non translation invariant topology induced by the canonical partial metric in the normed space.

    Full Text Available International election monitoring has been touted as a regional norm in the Western hemisphere, but recent reforms in Venezuela and Nicaragua substituted a diminished international role of electoral accompaniment. This article traces the initial acceptance and later limitation of international election monitoring in those countries to explore whether the change constitutes norm localization or norm defection. It concludes that the norm is not as well institutionalized in the hemisphere as conventionally thought, and that models need to assess together national and international monitoring capacities.

  4. Norm, gender, and bribe-giving: Insights from a behavioral game.

    Tian Lan

    Full Text Available Previous research has suggested that bribery is more normative in some countries than in others. To understand the underlying process, this paper examines the effects of social norm and gender on bribe-giving behavior. We argue that social norms provide information for strategic planning and impression management, and thus would impact participants' bribe amount. Besides, males are more agentic and focus more on impression management than females. We predicted that males would defy the norm in order to win when the amount of their bribe was kept private, but would conform to the norm when it was made public. To test this hypothesis, we conducted two studies using a competitive game. In each game, we asked three participants to compete in five rounds of creative tasks, and the winner was determined by a referee's subjective judgment of the participants' performance on the tasks. Participants were allowed to give bribes to the referee. Bribe-giving norms were manipulated in two domains: norm level (high vs. low and norm context (private vs. public, in order to investigate the influence of informational and affiliational needs. Studies 1 and 2 consistently showed that individuals conformed to the norm level of bribe-giving while maintaining a relative advantage for economic benefit. Study 2 found that males gave larger bribes in the private context than in the public, whereas females gave smaller bribes in both contexts. We used a latent growth curve model (LGCM to depict the development of bribe-giving behaviors during five rounds of competition. The results showed that gender, creative performance, and norm level all influence the trajectory of bribe-giving behavior.

  6. Socially Enforced Nepotism: How Norms and Reputation Can Amplify Kin Altruism.

    2016-01-01

    Kin selection, which can lead organisms to behave altruistically to their genetic relatives, works differently when-as is often the case in human societies-altruism can be boosted by social pressure. Here I present a model of social norms enforced by indirect reciprocity. In the model there are many alternative stable allocations of rewards ("distributional norms"); a stable norm is stable in the sense that each player is best off following the norm if other players do the same. Stable norms vary widely in how equally they reward players with unequal abilities. In a population of mixed groups (some group members follow one norm, some follow another, and some compromise) with modest within-group coefficients of relatedness, selection within groups favors those who compromise, and selection between groups favors generous generalized reciprocity rather than balanced reciprocity. Thus evolved social norms can amplify kin altruism, giving rise to a uniquely human mode of kin-based sociality distinct from spontaneous altruism among close kin, or cooperation among non-kin.

    Social norms in humans constrain individual behaviors to establish shared expectations within a social group. Previous work has probed social norm violations and the feelings that such violations engender; however, a computational rendering of the underlying neural and emotional responses has been lacking. We probed norm violations using a two-party, repeated fairness game (ultimatum game) where proposers offer a split of a monetary resource to a responder who either accepts or rejects the offer. Using a norm-training paradigm where subject groups are preadapted to either high or low offers, we demonstrate that unpredictable shifts in expected offers creates a difference in rejection rates exhibited by the two responder groups for otherwise identical offers. We constructed an ideal observer model that identified neural correlates of norm prediction errors in the ventral striatum and anterior insula, regions that also showed strong responses to variance-prediction errors generated by the same model. Subjective feelings about offers correlated with these norm prediction errors, and the two signals displayed overlapping, but not identical, neural correlates in striatum, insula, and medial orbitofrontal cortex. These results provide evidence for the hypothesis that responses in anterior insula can encode information about social norm violations that correlate with changes in overt behavior (changes in rejection rates). Together, these results demonstrate that the brain regions involved in reward prediction and risk prediction are also recruited in signaling social norm violations.

    Background Patient safety experts have postulated that increasing patient participation in communications during patient handovers will improve the quality of patient transitions, and that this may reduce hospital readmissions. Choosing strategies that enhance patient safety through improved handovers requires better understanding of patient experiences and preferences for participation. Objective The aim of this paper is to explore the patients’ experiences and perspectives related to the handovers between their primary care providers and the inpatient hospital. Methods A qualitative secondary analysis was performed, based on individual and focus group patient interviews with 90 patients in five European countries. Results The analysis revealed three themes: patient positioning in the handover process; prerequisites for patient participation and patient preferences for the handover process. Patients’ participation ranged from being the key actor, to sharing the responsibility with healthcare professional(s), to being passive participants. For active participation patients required both personal and social resources as well as prerequisites such as information and respect. Some patients preferred to be the key actor in charge; others preferred their healthcare professionals to be the key actors in the handover. Conclusions Patients’ participation is related to the healthcare system, the activity of healthcare professionals’ and patients’ capacity for participation. Patients prefer a handover process where the responsibility is clear and unambiguous. Healthcare organisations need a clear and well-considered system of responsibility for handover processes, that takes into account the individual patient's need of clarity, and support in relation to his/hers own recourses.

    Multiple environmental problems afflict our contemporary world and have been the subject of discussions during many international meetings. All declarations resulting from these meetings insist on including environmental problems and on environmental assessment (EA) as an important tool to achieve this. This book aims to reach three objectives. First, it introduces EA to people from different disciplines, and therefore it opens up the perspective of new disciplinary horizons. Second, the authors discuss EA as a socio-political process rather than emphasizing methodologies. Third, this book draws mainly on the experience in Francophone countries which is still poorly disseminated. This book focusses on process and actors. Thus, the subject matter is divided into five major parts: the history and major issues of EA from a sustainable development perspective (Chapters 1 to 3); the actors, i.e. the Project Proponent and consulting firms, the public, the decision maker and international actors (Chapters 4 to 7); methods and tools including public participation (Chapters 8 and 9); processes in practice through step by step processes in practice and case studies (Chapters 10 and 11); and, finally, recent and upcoming developments in EA, including elements of strategic environmental assessment (Chapters 12 and 13). An index facilitates searching for information. The reader is also invited to consult the book's website

    Children are less skilled than adults at making judgments about facial expression. This could be because they have not yet developed adult-like mechanisms for visually representing faces. Adults are thought to represent faces in a multidimensional face-space, and have been shown to code the expression of a face relative to the norm or average face in face-space. Norm-based coding is economical and adaptive, and may be what makes adults more sensitive to facial expression than children. This study investigated the coding system that children use to represent facial expression. An adaptation aftereffect paradigm was used to test 24 adults and 18 children (9 years 2 months to 9 years 11 months old). Participants adapted to weak and strong antiexpressions. They then judged the expression of an average expression. Adaptation created aftereffects that made the test face look like the expression opposite that of the adaptor. Consistent with the predictions of norm-based but not exemplar-based coding, aftereffects were larger for strong than weak adaptors for both age groups. Results indicate that, like adults, children's coding of facial expressions is norm-based. PsycINFO Database Record (c) 2013 APA, all rights reserved.

    Full Text Available ABSTRACT Objective Analyzing the relationship between socio-demographic characteristics of youth from the Landless Rural Workers’ Movement in Brazil (MST regarding the prevalence ratio being in accordance with gender norms. Method A cross-sectional study conducted during a Journey of Agroecology carried out in the State of Paraná with young people (15 to 29 years of both genders. Data collection was conducted through questionnaires. Data analysis compared variables regarding gender norms with sociodemographic variables, and a Prevalence Ratio (PR was calculated with a confidence interval (CI set at 95% in order to determine this relationship. Results The study sample was comprised of 147 young people. A higher prevalence was found in accordance with gender norms (PR with CI at 95% among women compared to men, and that sociodemographic characteristics (lower education level, those living in occupation camps, who do not have white skin and with religious belief were social indicators for such positioning among both genders. Conclusion The byproduct of a patriarchal gender system has led more young girls to internalization and a reaffirmation of gender norms, highlighting an important field for social nursing practices in order to contribute to the transformation of this reality.

    Full Text Available BACKGROUND: First experiences of tobacco use usually occur in adolescence. The recognition of social norms leading to youth smoking is hence necessary. We tried to assess the social norms among Iranian young cigarette and hookah smokers. METHODS: This cross-sectional study was conducted on 451 girls and 361 boys aging 20-25 years old who entered Isfahan and Kashan Universities (Iran in 2007. Demographic factors (age, gender, and age at smoking onset cigarette and hookah smoking status, having a smoking father or smoking friends and four related social norms were recorded. Binary logistic regression analysis was used to separately determine associations between hookah and cigarette smoking and the four social norm variables. RESULTS: Cigarette and hookah smokers had significant differences with nonsmokers in two social norms: “Perceived smoking by important characters” [odds ratio (OR = 1.35 in cigarette smokers and 1.58 in hookah smokers; P < 0.001] and “smoking makes gatherings friendly” (OR = 3.62 in cigarette smokers and 6.16 in hookah smokers; P < 0.001. Furthermore, cigarette and hookah smoking were significantly associated with having smoking friends. CONCLUSION: Highlighting the social norms leading to cigarette and hookah smoking may help policy makers develop comprehensive interventions to prevent smoking among adolescents.   Keywords: Cigarette, Hookah, Smoking, Social Norm

  16. Clinical ethics and values: how do norms evolve from practice?

    Science.gov (United States)

    Spranzi, Marta

    2013-02-01

    Bioethics laws in France have just undergone a revision process. The bioethics debate is often cast in terms of ethical principles and norms resisting emerging social and technological practices. This leads to the expression of confrontational attitudes based on widely differing interpretations of the same principles and values, and ultimately results in a deadlock. In this paper I would like to argue that focusing on values, as opposed to norms and principles, provides an interesting perspective on the evolution of norms. As Joseph Raz has convincingly argued, "life-building" values and practices are closely intertwined. Precisely because values have a more indeterminate meaning than norms, they can be cited as reasons for action by concerned stakeholders, and thus can help us understand how controversial practices, e.g. surrogate motherhood, can be justified. Finally, norms evolve when the interpretations of the relevant values shift and cause a change in the presumptions implicit in the norms. Thus, norms are not a prerequisite of the ethical solution of practical dilemmas, but rather the outcome of the decision-making process itself. Struggling to reach the right decision in controversial clinical ethics situations indirectly causes social and moral values to change and principles to be understood differently.

    2009-06-01

    Full Text Available The capacity to innovate for a sustainable development of alpine territories cannot depend only on economic, legal and political conditions defined by the State at national and international levels. It depends also on local conditions that situate historically and geographically the actors in a continuity of social and ecological relationships. This approach highlights the collective – thus organisational – dimensions of the innovation process, including the imagination, the development, the implementation and even the diffusion of a new practice. Our point of view is that for contributing to the sustainable development of the Alps, innovations need to change the ecological, political, social and cultural relationships engaging the actors in these territories. This change affects as much the object territory as the subject actor of the territory. This is why innovating in the Alps means also innovating the Alps and the alpine actors (Cosalp, 2008. Based on a research about local people’s participation in the management of alpine communal forests, the article shows the importance of local interactions involving actors of diverse occupation, gender, age and origins1.La capacité d’innovation pour un développement durable des territoires alpins ne peut dépendre uniquement de conditions économiques, légales et politiques définies par les Etats aux échelles nationale et internationale. Elle dépend aussi de conditions locales, qui situent historiquement et géographiquement les acteurs dans une continuité de relations sociales et écologiques. Cette perspective accentue l’importance de la dimension collective, donc organisationnelle, du processus d’innovation, allant de l’imagination, puis au développement, à la réalisation – voire la diffusion – d’une nouvelle pratique. Le point de vue de cet article est qu’une innovation, pour contribuer au développement durable des Alpes, doit changer les relations

  2. From consultation to deliberation? Tracing deliberative norms in EIA frameworks in Swedish roads planning

    Isaksson, Karolina; Richardson, Tim; Olsson, Krister

    2009-01-01

    This paper presents the results of an analysis of deliberative norms in the framework for Environmental Impact Assessment (EIA) in roads planning in Sweden. The more specific question is how this framework has responded to the shift towards more deliberative approaches to planning and decision making, advocated in planning theory and policy literature over the last decade. The analysis, which compares the current framework and guidance with an earlier iteration, identifies a shift towards deliberation; deliberative norms are present, and even dominate recent guidance. However, an instrumental norm permeates both the former and the current guidance, suggesting that even as a language of consultation is replaced by one of deliberation, the intention remains to secure and legitimise a smooth development pathway. Evidence from interviews with professionals working in the Swedish EIA system highlights the difficulties of navigating these uncertainties in practice. By opening up critical analysis of deliberative norms as they shape the conditions for practice, this study contributes to the continuous development of planning practice, by supporting a more normatively reflexive approach to framework-design.

    Industry with an activity of processing natural resources from crust of earth as raw materials could cause natural radioactivity in crust of earth to be accumulated in waste, by product and or main product of that industry. Natural radioactive elements which are mobilized and then accumulated in end industry process are known as NORM (Naturally Occurring Radioactive Materials). NORM have a potential radiological impact such as external and internal radiation exposure. Therefore, the existence of NORM in these non-nuclear industries should be studied in order to handle properly the radiological impact of those material to the industrial workers, member of the public and the surrounding environment. This paper describes the non nuclear industrial sectors in Indonesia that have potential NORM sources and radiation safety aspects in connecting with NORM. (author)

    Full Text Available In this paper on the basis of the notions of competence, forecasting, prognostical competence the author’s definition of future actors-teachers’ prognostical competence is developed. Under prognostic competence of future actors-teachers we understand a special competence that allows the subject, engaged in professional activities as a performer of roles in the theater (movies, TV, as well as performing teaching activities in the field of arts, to receive the necessary anticipatory information about the phenomenon under investigation (on performing roles in the theatre, films, and television, on the learning process and actors-teachers training. Components of prognostical competence as a type of competencies (cognitive, instrumental and operational and motivational-value are singled out. The feature of the future actor-teacher’s professional activities in the context of prognostical competence is viewed. It is the simultaneous solving the artistic-creative, organizational and teaching-upbringing problems.Purpose. The purpose of the paper is the definition of prognostical competence of future teachers-actors.Methodology. In the research the methods of theoretical level are used: comparison, analysis and synthesis, generalization, concretization; analytical methods; idealization and modeling.Result. The result of the research is the development of the author’s concept of «prognostical competence of the future teachers-actors».Practical implications. Application of the results: The results may be applied to the work of teachers-actors’ trainers as well as the researchers in Pedagogy.

  7. Oral-diadochokinesis rates across languages: English and Hebrew norms.

    Oro-facial and speech motor control disorders represent a variety of speech and language pathologies. Early identification of such problems is important and carries clinical implications. A common and simple tool for gauging the presence and severity of speech motor control impairments is oral-diadochokinesis (oral-DDK). Surprisingly, norms for adult performance are missing from the literature. The goals of this study were: (1) to establish a norm for oral-DDK rate for (young to middle-age) adult English speakers, by collecting data from the literature (five studies, N=141); (2) to investigate the possible effect of language (and culture) on oral-DDK performance, by analyzing studies conducted in other languages (five studies, N=140), alongside the English norm; and (3) to find a new norm for adult Hebrew speakers, by testing 115 speakers. We first offer an English norm with a mean of 6.2syllables/s (SD=.8), and a lower boundary of 5.4syllables/s that can be used to indicate possible abnormality. Next, we found significant differences between four tested languages (English, Portuguese, Farsi and Greek) in oral-DDK rates. Results suggest the need to set language and culture sensitive norms for the application of the oral-DDK task world-wide. Finally, we found the oral-DDK performance for adult Hebrew speakers to be 6.4syllables/s (SD=.8), not significantly different than the English norms. This implies possible phonological similarities between English and Hebrew. We further note that no gender effects were found in our study. We recommend using oral-DDK as an important tool in the speech language pathologist's arsenal. Yet, application of this task should be done carefully, comparing individual performance to a set norm within the specific language. Readers will be able to: (1) identify the Speech-Language Pathologist assessment process using the oral-DDK task, by comparing an individual performance to the present English norm, (2) describe the impact of language

  8. Ways of giving benefits in marriage: norm use, relationship satisfaction, and attachment-related variability.

    Couples reported on bases for giving support and on relationship satisfaction just prior to and approximately 2 years into marriage. Overall, a need-based, noncontingent (communal) norm was seen as ideal and was followed, and greater use of this norm was linked to higher relationship satisfaction. An exchange norm was seen as not ideal and was followed significantly less frequently than was a communal norm; by 2 years into marriage, greater use of an exchange norm was linked with lower satisfaction. Insecure attachment predicted greater adherence to an exchange norm. Idealization of and adherence to a communal norm dropped slightly across time. As idealization of a communal norm and own use and partner use of a communal norm decreased, people high in avoidance increased their use of an exchange norm, whereas people low in avoidance decreased their use of an exchange norm. Anxious individuals evidenced tighter links between norm use and marital satisfaction relative to nonanxious individuals. Overall, a picture of people valuing a communal norm and striving toward adherence to a communal norm emerged, with secure individuals doing so with more success and equanimity across time than insecure individuals.

  11. Socially Enforced Nepotism: How Norms and Reputation Can Amplify Kin Altruism.

    Directory of Open Access Journals (Sweden)

    Doug Jones

    Full Text Available Kin selection, which can lead organisms to behave altruistically to their genetic relatives, works differently when-as is often the case in human societies-altruism can be boosted by social pressure. Here I present a model of social norms enforced by indirect reciprocity. In the model there are many alternative stable allocations of rewards ("distributional norms"; a stable norm is stable in the sense that each player is best off following the norm if other players do the same. Stable norms vary widely in how equally they reward players with unequal abilities. In a population of mixed groups (some group members follow one norm, some follow another, and some compromise with modest within-group coefficients of relatedness, selection within groups favors those who compromise, and selection between groups favors generous generalized reciprocity rather than balanced reciprocity. Thus evolved social norms can amplify kin altruism, giving rise to a uniquely human mode of kin-based sociality distinct from spontaneous altruism among close kin, or cooperation among non-kin.

  12. Local authorities and electricity: territories, actors and issues within the local public service in France

    2005-06-01

    In France, the role of local authorities in the organization of the electricity supply system is largely unknown mainly due to the size of the state-owned utility Electricite de France (EDF). Local authorities and their groupings played a major role in the electrification of the national territory and have kept important prerogatives as conceding authorities of this service of general interest. These groupings also became the tools of the soft power of local actors. The geopolitical analysis of the relationships between local municipalities and electric power stakeholders shows the diversity of actors and opinions. Stuck between market liberalization issues and decentralization to local authorities, these groupings tend to reinforce their competencies. Furthermore, decentralization goes along with a reinforcement of the political involvement in local energy policy and with conflicts on the adequate territorial scale for theses policies. (author)

    In linear prediction of speech, the 1-norm error minimization criterion has been shown to provide a valid alternative to the 2-norm minimization criterion. However, unlike 2-norm minimization, 1-norm minimization does not guarantee the stability of the corresponding all-pole filter and can generate...... saturations when this is used to synthesize speech. In this paper, we introduce two new methods to obtain intrinsically stable predictors with the 1-norm minimization. The first method is based on constraining the roots of the predictor to lie within the unit circle by reducing the numerical range...... based linear prediction for modeling and coding of speech....

    Oil and gas industry in the Great Jamahiriya is one of those industries that were accompanied with generation of some solid and liquid waste, which associated with risks that might lead to harmful effects to the man and the environment. Among those risks the continuous increase of radioactivity levels above natural radioactive background around operating oil fields, due to accumulation of solid and liquid radioactive scales and sludge as well as contaminated produced water that contain some naturally occurring radioactive materials ( NORM/TE-NORM). Emergence of NORM/TE-NORM in studied area noticed when the natural background radioactivity levels increased around some oil fields during end of 1998, For this study, six field trips and a radiation surveys were conducted within selected oil fields that managed and owned by six operating companies under NOC, in order to determine the effective radiation dose in contrast with dose limits set by International Counsel of Radiation Protection(ICRP),and International Atomic Energy Agency(IAEA) Additionally solid samples in a form of scales and liquid samples were also taken for further investigation and laboratory analysis. Results were tabulated and discussed within the text .However to be more specific results pointed out to the fact that existence of NORM/TE-NORM as 226 Ra, 228 Ra, within some scale samples from surface equipment in some oil and gas fields in Jamahiriya were significant. As a result of that, the workers might receive moderate radiation dose less than the limits set by ICRP,IAEA, and other parts of the world producing oil and gas. Results predicted that within the investigated oil fields if workers receive proper training about handling of NORM/TE-NORM and follow the operating procedure of clean ups, work over and maintenance plane carefully, their committed exposure from NORM/TE-NORM will be less than the set limits by ICRP and IAEA.

    Fátima Portilho

    2009-10-01

    Full Text Available This article presents reflections on new market actors, and economic social movements in particular - that is, those in which actors build a new culture of political action that seeks to reappropriate the economy through their own values. Some examples of this are the movements organized around “solidarity economics”, fair trade, geographic indications, “slow food” and consumer organization. This interface of social movements and the market may be the most marked, differentiated and polemic trait of contemporary political mobilizations. Nonetheless, beyond economic social movements, this article simultaneously emphasizes and problematizes political action within the sphere of individual consumption, that is, that which has been referred to as “political consumption”. Keywords: economic social movements, consumer movements, political consumption.

    2015-12-01

    Full Text Available As the main new result, under certain hypotheses, for free vibration problems, the norm equivalence of the displacement vector $ y(t $ and the velocity vector $ \\dot{y}(t $ is proven. The pertinent inequalities are applied to derive some two-sided bounds on $ y(t $ and $ \\dot{y}(t $ that are known so far only for the state vector $ x(t=[y^T(t, \\dot{y}^T(t]^T $. Sufficient algebraic conditions are given such that norm equivalence between $ y(t $ and $ \\dot{y}(t $ holds, respectively, does not hold, as the case may be. Numerical examples illustrate the results for vibration problems of n degrees of freedom with $ n \\in \\{ 1, 2, 3, 4, 5 \\} $ by computing the mentioned algebraic conditions and by plotting the graphs of $ y(t $ and $ \\dot{y}(t $. Some notations and definitions of References Kohaupt (2008b, 2011 are necessary and are therefore recapitulated. The paper is of interest to Mathematicians and Engineers.

    Mollborn, Stefanie

    2011-01-01

    African American and Latino teenagers and communities are frequently assumed to have weaker norms against teenage pregnancy than whites. Despite their importance, adolescents’ norms about teenage pregnancy have not been measured or their correlates and consequences documented. This study examines individual-level and contextual variation in adolescents’ embarrassment at the prospect of a teenage pregnancy and its relationship with subsequent teenage pregnancy. Descriptive analyses find that norms vary by gender and individual- and neighborhood-level race, ethnicity, and socioeconomic status (SES). In multivariate analyses, neighborhood-level racial/ethnic associations with embarrassment are explained by neighborhood-level SES. Embarrassment is associated with a lower likelihood of subsequent teenage pregnancy but does not mediate racial, ethnic, or socioeconomic influences, underscoring the importance of both norms and structural factors for understanding teenage fertility.

    This study applies an integrated moral obligation model to examine the role of environmental and cultural values, and beliefs in the activation of landowner conservation norms. Data for this study were collected through a self-administered survey of riparian landowners in two Minnesota watersheds: Sand Creek and Vermillion River watersheds. Study findings suggest that collectivistic and biospheric–altruistic values form the bases for the activation of personal norms. Further, beliefs about local responsibility and ability to act influence personal norms to protect water resources. Findings suggest that landowners’ personal norms of water conservation are more likely to be activated by conservation strategies that appeal to biospheric–altruistic and collectivistic values, emphasize adverse consequences of water pollution, highlight water resource protection as a local responsibility, and provide the resources needed to protect water resources.

  6. Searching for realism, structure and agency in Actor Network Theory.

    Science.gov (United States)

    Elder-Vass, Dave

    2008-09-01

    Superficially, Actor Network Theory (ANT) and critical realism (CR) are radically opposed research traditions. Written from a realist perspective, this paper asks whether there might be a basis for finding common ground between these two traditions. It looks in turn at the questions of realism, structure, and agency, analysing the differences between the two perspectives and seeking to identify what each might learn from the other. Overall, the paper argues that there is a great deal that realists can learn from actor network theory; yet ANT remains stunted by its lack of a depth ontology. It fails to recognize the significance of mechanisms, and of their dependence on emergence, and thus lacks both dimensions of the depth that is characteristic of critical realism's ontology. This prevents ANT from recognizing the role and powers of social structure; but on the other hand, realists would do well to heed ANT's call for us to trace the connections through which structures are constantly made and remade. A lack of ontological depth also underpins ANT's practice of treating human and non-human actors symmetrically, yet this remains a valuable provocation to sociologists who neglect non-human entities entirely.

  11. Potential environmental and regulatory implications of naturally occurring radioactive materials (NORM)

    International Nuclear Information System (INIS)

    Paschoa, A.S.

    1998-01-01

    The immense volume of naturally occurring radioactive materials (NORM) wastes produced annually by extracting industries throughout the world deserves to come to the attention of international and national environmental protection agencies and regulatory bodies. Although a great deal of work has been done in the fields of radiation protection and remedial actions concerning uranium and other mines, the need to dispose of diffuse NORM wastes will have environmental and regulatory implications that thus far are not fully appreciated. NORM wastes constitute, by and large, unwanted byproducts of industrial activities as diverse as thorium and uranium milling, niobium, tin and gold mining extraction, water treatment, and the production of oil, gas, phosphate fertilizer, coal fire and aluminium. The volumes of NORM wastes produced annually could reach levels so high that the existing low level radioactive waste (LLRW) facilities would be readily occupied by NORM if controlled disposal procedures were not adopted. On the other hand, NORM cannot just be ignored as being below radiological concern (BRC) or lower than exempt concentration levels (ECLs), because sometimes NORM concentrations reach levels as high as 1 x 10 3 kBq/kg for 226 Ra, and not much less for 228 Ra. Unfortunately, thus far, there is not enough information available concerning NORM wastes in key industries, though the international scientific community has been concerned, for a long time now, with technologically enhanced natural radiation exposures (TENRE). This article is written with the intention of examining, to the extent possible, the potential environmental and regulatory implications of NORM wastes being produced in selected industries.

  12. A case study on the formation and sharing process of science classroom norms

    2016-03-01

    The teaching and learning of science in school are influenced by various factors, including both individual factors, such as member beliefs, and social factors, such as the power structure of the class. To understand this complex context affected by various factors in schools, we investigated the formation and sharing process of science classroom norms in connection with these factors. By examining the developmental process of science classroom norms, we identified how the norms were realized, shared, and internalized among the members. We collected data through classroom observations and interviews focusing on two elementary science classrooms in Korea. From these data, factors influencing norm formation were extracted and developed as stories about norm establishment. The results indicate that every science classroom norm was established, shared, and internalized differently according to the values ingrained in the norms, the agent of norm formation, and the members' understanding about the norm itself. The desirable norms originating from values in science education, such as having an inquiring mind, were not established spontaneously by students, but were instead established through well-organized norm networks to encourage concrete practice. Educational implications were discussed in terms of the practice of school science inquiry, cultural studies, and value-oriented education.

    Private business and philanthropic organizations have played a prominent role in the response to the Ebola outbreak in West Africa and the support of global health governance more broadly. While this involvement may appear to be novel or unprecedented, this article argues that this active role for private actors and philanthropies actually mirrors the historical experience of cross-border health governance in the first half of the twentieth century. By examining the experiences, roles and criticisms of the Rockefeller Foundation's International Health Division and the Bill and Melinda Gates Foundation, it is possible to identify potential opportunities for better cooperation between public and private actors in global health governance.

    There are basically two modeling approaches applicable to analyzing an actor-partner interdependence model: the multilevel modeling (hierarchical linear model) and the structural equation modeling. This article explains how to use these two models in analyzing an actor-partner interdependence model and how these two approaches work differently. As an empirical example, marital conflict data were used to analyze an actor-partner interdependence model. The multilevel modeling and the structural equation modeling produced virtually identical estimates for a basic model. However, the structural equation modeling approach allowed more realistic assumptions on measurement errors and factor loadings, rendering better model fit indices.

    In this study, we have used a single link system with a pair of muscles that are excited with alpha and gamma signals to achieve both point to point and oscillatory movements with variable amplitude and frequency.The system is highly nonlinear in all its physical and physiological attributes. The major physiological characteristics of this system are simultaneous activation of a pair of nonlinear muscle-like-actuators for control purposes, existence of nonlinear spindle-like sensors and Golgi tendon organ-like sensor, actions of gravity and external loading. Transmission delays are included in the afferent and efferent neural paths to account for a more accurate representation of the reflex loops.A reinforcement learning method with an actor-critic (AC) architecture instead of middle and low level of central nervous system (CNS), is used to track a desired trajectory. The actor in this structure is a two layer feedforward neural network and the critic is a model of the cerebellum. The critic is trained by state-action-reward-state-action (SARSA) method. The critic will train the actor by supervisory learning based on the prior experiences. Simulation studies of oscillatory movements based on the proposed algorithm demonstrate excellent tracking capability and after 280 epochs the RMS error for position and velocity profiles were 0.02, 0.04 rad and rad/s, respectively.

    We study the effective kinetic energy of scalar fields for two classes of supersymmetric theories. In theories with very large VEVs of scalar fields, as proposed by Witten, the use of the renormalization group improved effective action prevents the appearance of negative norm states. For simpler theories a general criterium for the absence of negative norm states is given, which is violated in a model with O(N)-symmetry proposed recently. (orig.)

    Containing the advance of deforestation in Brazilian Amazonia requires understanding the roles and movements of the actors involved. The importance of different actors varies widely among locations within the region, and also evolves at any particular site over the course of frontier establishment and consolidation. Landless migrants have significant roles in clearing the land they occupy and in motivating landholders to clear as a defense against invasion or expropriation. Colonists in offic...

    The assessment of individuals on abilities or other characteristics is based on comparison to a representative sample. General population norms provide an appropriate reference group when the distribution of scores in the sample can be expected to be similar to those for the general population (e.g., comparing high school students at a particular school to national high school norms on a college entrance test). Specialized norms are needed, however, when subsets of the population differ from the population at large. Military pilot trainees represent a special population; they are highly screened on cognitive ability and other characteristics thought to be related to job performance. Other characteristics (e.g., personality) are thought to be "self-selected," resulting in distinctive profiles. Normative tables were developed for U.S. Air Force pilot trainees for two widely used tests, the Multidimensional Aptitude Battery-II (MAB-II) and NEO Personality Inventory-Revised (NEO PI-R). The MAB-II and NEO PI-R were administered to large samples of USAF cadets, ROTC students, and officers selected for pilot training. The mean MAB-II full-scale IQ was about 1.5 SD above the adult population norm and was much less variable, supporting the need for specialized norms. Tables showing the percentile equivalents are provided for use by clinicians. Use of these tables, in addition to, or in lieu of, commercially published norms, will prove helpful when clinical psychologists perform assessments on pilots; in particular when evaluating them for return-to-duty status following a disqualifying condition that may have affected cognitive functioning or emotional stability.

    Full Text Available Background: During the past two decades, a great deal of research has been conducted on developing affective norms for words in various languages, showing that there is an urgent need to create such norms in Persian language, too. The present study intended to develop a set of 362 Persian words rated according to their emotional valence, arousal, imageability, and familiarity so as to prepare the ground for further research on emotional word processing. This was the first attempt to set affective norms for Persian words in the realm of emotion.  Methods: Prior to the study, a multitude of words were selected from Persian dictionary and academic books in Persian literature. Secondly, three independent proficient experts in the Persian literature were asked to extract the suitable words from the list and to choose the best (defined as grammatically correct and most often used. The database normalization process was based on the ratings by a total of 88 participants using a 9-point Likert scale. Each participant evaluated about 120 words on four different scales.  Results: There were significant relationships between affective dimensions and some psycholinguistic variables. Also, further analyses were carried out to investigate the possible relationship between different features of valences (positive, negative, and neutral and other variables included in the dataset.  Conclusion: These affective norms for Persian words create a useful and valid dataset which will provide researchers with applying standard verbal materials as well as materials applied in other languages, e.g. English, German, French, Spanish, Portuguese, Dutch, etc.

    Individuals' behaviors are influenced by those of others in their social environment (i.e., descriptive norms), as well as by how individuals perceive they should behave in that environment (e.g., injunctive norms). Although social norms are thought to play an important role in hepatitis B virus (HBV) screening, limited theoretical or empirical guidance exists on how the underlying process works. In addition, norms are social phenomena that are spread through family discussion about the importance of getting HBV screening. Using the theory of normative social behavior (TNSB), this study examined the roles of injunctive norms (IN), descriptive norms (DN), and family discussion in HBV screening behavior among Asian Americans. Data from a survey of Asian Americans in the Baltimore Washington metropolitan area (N = 877) were used to test underlying theoretical propositions. DN and family discussion emerged as key factors in HBV screening behavior among all Asian Americans. IN were associated with HBV screening among Chinese and Korean Americans, but not for Vietnamese Americans. Family discussion moderated the influence of DN on behavior among Chinese and Vietnamese Americans. However, the main effect of DN on screening behavior was not modified by IN (no interactions between DN and IN). The results indicate that family discussion and social norms are integral in enabling Asian Americans to undergo HBV screening and warrant sensitivity in the design and implementation of a liver cancer prevention program in this high-risk group of Asian Americans.

    The present study focuses mainly on the relationship between psychological constructs and ecological behaviour. Empirical analysis links personal values, ecological beliefs, consequences of environmental conditions, denial of ecological obligation, environmental control, personal norms and environment protection behaviour. Survey data from a path analysis of a Spanish sample of 403 individuals were used, showing that ecological beliefs, personal norms and eco-altruistic values have become the main psychological explanatory variables of environment protective behaviour. Ecological beliefs, when measured by the New Ecological Paradigm Scale, affected ecological behaviour decisively. Environmental and altruistic values were shown to be related to moral obligation, and a basic variable to understand behaviour. Personal norm mediated the effects of values and environmental control on ecological behaviour.

    Researchers seeking to understand teen sexual behaviors often turn to age norms, but they are difficult to measure quantitatively. Previous work has usually inferred norms from behavioral patterns or measured group-level norms at the individual level, ignoring multiple reference groups. Capitalizing on the multilevel design of the Add Health survey, we measure teen pregnancy norms perceived by teenagers, as well as average norms at the school and peer network levels. School norms predict boys’ perceived norms, while peer network norms predict girls’ perceived norms. Peer network and individually perceived norms against teen pregnancy independently and negatively predict teens’ likelihood of sexual intercourse. Perceived norms against pregnancy predict increased likelihood of contraception among sexually experienced girls, but sexually experienced boys’ contraceptive behavior is more complicated: When both the boy and his peers or school have stronger norms against teen pregnancy he is more likely to contracept, and in the absence of school or peer norms against pregnancy, boys who are embarrassed are less likely to contracept. We conclude that: (1) patterns of behavior cannot adequately operationalize teen pregnancy norms, (2) norms are not simply linked to behaviors through individual perceptions, and (3) norms at different levels can operate independently of each other, interactively, or in opposition. This evidence creates space for conceptualizations of agency, conflict, and change that can lead to progress in understanding age norms and sexual behaviors. PMID:25104920

    The article shows that care in developing countries is a complex matter that cannot be reduced to corrupt practices. The literature on informal payments highlights the role played by corrupt practices in the health sector and tends to attribute corruption to a so-called ‘endemic culture of gifts’...... to the fabrication of the practical norms that regulate the daily functioning of health facilities and shape people’s behaviour.......’. However, as the case of the emergency service of Niamey National Hospital suggests the interactions between civil servants and users in health facilities have little to do with a traditional culture. They are better understood through the lens of practical norms. Furthermore, as the authors demonstrates...... of the services provided by the medical staff, it also depends on the qualifications of the persons (relatives, friends) accompanying the patient. In Niger (and other developing countries), the patient’s attendant is a crucial component of the organisation and the effectiveness of health facilities in emergency...

    As a refence a standard of 'cured norm' is proposed. The patients who come under the 'cured norm' category are those without previous myocardial infarctions and who are free of symptoms after a successful transluminal coronary angioplasty (TCA) with a normalized exercise ECG. Global and sectorial parameters of radionuclide-vetriculography (RNV) and 201 Tl-myocardial-scintigraphy ( 201 Tl-MS) are in good accordance with the published data from other authors. An improvement is found after successful TCA but results are even better in the special 'cured norm' group indicating an additional normalization. Sensitivity and specificity based on the 'cured norm' is comparable with the results published by others. From these results we conclude that the 'cured norm' is suitable for clinical use. (orig.)

    Study of marketing norm perception among medical representatives is an under-portrayed component that deserves further perusal in the pharmaceutical industry. The purpose of this study is to find out the perception of marketing norms among medical representatives. The research design is quantitative and cross sectional study with medical representatives as unit of analysis. Data is collected from medical representatives (n=300) using a simple random and cluster sampling using a structured questionnaire. Results indicate that there is no difference in the perception of marketing norms among male and female medical representatives. But there is a difference in opinion among domestic and multinational company's medical representatives. Educational back ground of medical representatives also shows the difference in opinion among medical representatives. Degree holders and multinational company medical representatives have high perception of marketing norms compare to their counterparts. The researchers strongly believe that mandatory training on marketing norms is beneficial in decision making process during the dilemmas in the sales field.

  12. Is carbon lock-in blocking investments in the hydrogen economy? A survey of actors' strategies

    International Nuclear Information System (INIS)

    Bento, Nuno

    2010-01-01

    The difficulty of introducing hydrogen and fuel cells in the market stems from the fact that they are not an evolutionary innovation such as biofuels or hybrid cars. Instead they create a disruption in technological utilization. The domination of oil technologies sets a socio-economical context favoring actors involved in the current paradigm, and gives less opportunity to alternative fuels to develop and challenge the status quo. If this hypothesis is correct, then companies interested in the hydrogen economy would not become active because of an unstable context or contradictory interests concerning the replacement of the present system. A review of actions and announcements of main actors shows that technology readiness and the absence of infrastructure are the major justifications to delay investments. Some measures are discussed, which could be deployed in order to reduce uncertainties, such as regulation of carbon emissions from cars, technological subvention, and partnerships for infrastructure implementation.

    If one sector in recent decades has been a byword for how difficult it is to anticipate future developments at the global level, it has been the energy sector. We have seen fears over the dangers of a hydrocarbon shortage, the announcement of 'peak oil' and a boom in shale gas and oil. Forecasts based on major trends within the field have been revised as non-conventional sources with a substantial impact on price levels have emerged. Added to this is the need to confront climate change and hence to revamp our modes of energy production to give an enhanced role to renewables. In such a context, as Jean-Marie Chevalier stresses here, it is quite tricky to say how energy prices will develop or how energy production systems will change. This is why, in addition to the overview of possible developments in the prices of oil, natural gas and coal which this article provides, it particularly stresses the many elements of uncertainty that still prevail. Chevalier demonstrates the multiplicity of factors - and actor - involved in the way energy systems and prices develop and highlights the key elements that will play a role in enhancing or curbing those developments in the medium-to-long term.

    Full text: The need for the specific international publication dedicated to the radiation protection and regulatory issues associated with exposures of workers, general public and the environment in situations involving naturally occurring radioactive materials (Norm) has been identified almost ten years ago. In the 1990-s the journal entitled 'the NORM report' was published in the U.S.A. mainly dealt with legislative updates in regard to NORM in different states and at a later stage Canada. The printed journal has a wide following among industries and regulatory authorities concerned with NORM. Unfortunately, the publishing ceased in early 2000-s with the passing of the editor, Dr. Peter Gray. The publication of 'the NORM Report' will re-commence in early 2008 as an internet based publication that is intended to be a resource for: Regulatory authorities exchange information in regards to the 'NORM-specific' regulations and guidelines applicable in their jurisdictions. They are also able to collect details from authorities in other countries/states - to ensure the adoption of the most appropriate regulatory standards to similar levels of radiation exposure and the same industries world-wide (not only within the USA), a) Researches, who will be able to publish the results of their studies in a journal specifically dedicated to naturally occurring radioactive materials and b) Industries that use, process, and generate - to facilitate the information exchange in regards to best practices in controlling radiation exposure and in the disposal or re-use of NORM-containing materials. The intent of the presentation is to obtain the opinion of a wider radiation protection community of the usefulness and the contents of the publication of 'the NORM Report' to ensure the journal meets its state objectives.

    2015-01-01

    Full Text Available Background: While norms are important for educational attainment, especially in the developing world, there are relatively few studies on this topic. This paper, which explores attitudes toward gender equality in education among Bangladeshis, should therefore be of interest to both academics and policymakers. Objective: In this paper, we seek to identify which factors affect the norms regarding the education of girls and boys, as well as of women and men, across two cohorts of married women in Bangladesh. In particular, we look at the relative importance of an individual woman's own educational background and those of her spouse and other family members in shaping her attitudes toward gender equality in education. Methods: We analyze a rich household dataset for Bangladesh from the World Bank Survey on Gender Norms in Bangladesh, which was conducted in 2006. We use linear probability models to examine the determinants of gender education norms. We also decompose the intergenerational gender norms gap using the Oaxaca-Blinder composition (total and detailed, taking into account several technical issues related to the computation of standard errors and the use of dummy variables in detailed decompositions. Results: Education norms were found to differ substantially across cohorts, with women from the younger cohort expressing far more positive views than older female respondents regarding education for both girls and women. The effect of education on norms could be found among both the respondents and their husbands, as well as among the older women in the household. This suggests that educational norms are shared both within married couples and across generations. Conclusions: Our results indicate that the far-reaching changes in female education in Bangladesh have had equally far-reaching effects on the perceived value of education for girls relative to education for boys.

    Public Private Partnerships (PPP) are increasingly utilized as a public health strategy for strengthening health systems and have become a core component for the delivery of TB control services in India, as promoted through national policy. However, partnerships are complex systems that rely on relationships between a myriad of different actors with divergent agendas and backgrounds. Relationship is a crucial element of governance, and relationship building an important aspect of partnerships. To understand PPPs a multi-disciplinary perspective that draws on insights from social theory is needed. This paper demonstrates how social theory can aid the understanding of the complex relationships of actors involved in implementation of Public-Private Mix (PPM)-TB policy in India. Ethnographic research was conducted within a district in a Southern state of India over a 14 month period, combining participant observations, informal interactions and in-depth interviews with a wide range of respondents across public, private and non-government organisation (NGO) sectors. Drawing on the theoretical insights from Bourdieu's "theory of practice" this study explores the relationships between the different actors. The study found that programme managers, frontline TB workers, NGOs, and private practitioners all had a crucial role to play in TB partnerships. They were widely regarded as valued contributors with distinct social skills and capabilities within their organizations and professions. However, their potential contributions towards programme implementation tended to be unrecognized both at the top and bottom of the policy implementation chain. These actors constantly struggled for recognition and used different mechanisms to position themselves alongside other actors within the programme that further complicated the relationships between different actors. This paper demonstrates that applying social theory can enable a better understanding of the complex relationship

    Conventional retailers play a significant role in selling organic food, and therefore, it is important to understand how the demand - supply chain of organic food works as an element of the conventional food system. The proportion of organic food in the conventional food chains is small, and this poses a great challenge to the performance of the chain. Surveys and case specific studies on consumers and supply chain actors indicate that the changes in the conventional food system have an impac...

  19. The role of multisensor data fusion in neuromuscular control of a sagittal arm with a pair of muscles using actor-critic reinforcement learning method.

    Golkhou, V; Parnianpour, M; Lucas, C

    2004-01-01

    In this study, we consider the role of multisensor data fusion in neuromuscular control using an actor-critic reinforcement learning method. The model we use is a single link system actuated by a pair of muscles that are excited with alpha and gamma signals. Various physiological sensor information such as proprioception, spindle sensors, and Golgi tendon organs have been integrated to achieve an oscillatory movement with variable amplitude and frequency, while achieving a stable movement with minimum metabolic cost and coactivation. The system is highly nonlinear in all its physical and physiological attributes. Transmission delays are included in the afferent and efferent neural paths to account for a more accurate representation of the reflex loops. This paper proposes a reinforcement learning method with an Actor-Critic architecture instead of middle and low level of central nervous system (CNS). The Actor in this structure is a two layer feedforward neural network and the Critic is a model of the cerebellum. The Critic is trained by the State-Action-Reward-State-Action (SARSA) method. The Critic will train the Actor by supervisory learning based on previous experiences. The reinforcement signal in SARSA is evaluated based on available alternatives concerning the concept of multisensor data fusion. The effectiveness and the biological plausibility of the present model are demonstrated by several simulations. The system showed excellent tracking capability when we integrated the available sensor information. Addition of a penalty for activation of muscles resulted in much lower muscle coactivation while keeping the movement stable.

  20. Perceived eating norms and children's eating behaviour: An informational social influence account.

    2017-06-01

    There is initial evidence that beliefs about the eating behaviour of others (perceived eating norms) can influence children's vegetable consumption, but little research has examined the mechanisms explaining this effect. In two studies we aimed to replicate the effect that perceived eating norms have on children's vegetable consumption, and to explore mechanisms which may underlie the influence of perceived eating norms on children's vegetable consumption. Study 1 investigated whether children follow perceived eating norms due to a desire to maintain personal feelings of social acceptance. Study 2 investigated whether perceived eating norms influence eating behaviour because eating norms provide information which can remove uncertainty about how to behave. Across both studies children were exposed to vegetable consumption information of other children and their vegetable consumption was examined. In both studies children were influenced by perceived eating norms, eating more when led to believe others had eaten a large amount compared to when led to believe others had eaten no vegetables. In Study 1, children were influenced by a perceived eating norm regardless of whether they felt sure or unsure that other children accepted them. In Study 2, children were most influenced by a perceived eating norm if they were eating in a novel context in which it may have been uncertain how to behave, as opposed to an eating context that children had already encountered. Perceived eating norms may influence children's eating behaviour by removing uncertainty about how to behave, otherwise known as informational social influence. Copyright © 2017 The Authors.
