Proliferation: myth or reality?

International Nuclear Information System (INIS)

2005-01-01

This article analyzes the proliferation approach, its technical condition and political motivation, and the share between the myth (political deception, assumptions and extrapolations) and the reality of proliferation. Its appreciation is complicated by the irrational behaviour of some political actors and by the significant loss of the non-use taboo. The control of technologies is an important element for proliferation slowing down but an efficient and autonomous intelligence system remains indispensable. (J.S.)

The single greatest threat to U.S. homeland security remains the proliferation of nuclear weapons, especially among terrorists and other non-state actors who are not governed by the Non-Proliferation Treaty. One of the most important tools for combating terrorism among such rogue actors is counter-financing. Without funding, terrorists cannot acquire, maintain, or deploy nuclear weapons. According to the official report of the 9/11 Commission, counter-financing could have prevented the attacks of September 11, 2001. Unfortunately, no single country can defeat global terrorism. Successful counter-financing requires significant international cooperation. Since 2001, the United States and the European Union, despite vastly different approaches to intelligence gathering, have shared information through the Terrorist Finance Tracking Program (TFTP). That shared information allows authorities to trace suspicious transactions, identify culprits, and map out global terrorist networks. The TFTP successfully thwarted a 2011 plot to assassinate the Saudi Arabian Ambassador to the U.S. and multiple threats during the 2012 Summer Olympics in London; it also aided in the investigation of the 2013 Boston Marathon bombing. That program is necessary but not sufficient. To strengthen our ability to detect and disrupt terrorist plotting and prevent nuclear proliferation, we must expand and coordinate two additional transnational measures: (1) the Society for Worldwide Interbank Financial Telecommunications (SWIFT), a standardized global messaging network for financial institutions to quickly, accurately, and securely send and receive money transfer instructions, and (2) International Bank Account Numbers (IBAN) to identify individual accounts involved in international transactions. Both initiatives were incompletely adopted in the wake of 9/11, but most global banks use one or neither. More fully implementing and coordinating these two systems would allow for coherent information

Which future for nuclear counter-proliferation?; Quel avenir pour la contre-proliferation nucleaire?

2010-07-15

Dealing with the case of nuclear weapons possessed by nuclear states (but not eventually by terrorists), the author first identifies the constants of counter-proliferation: it is linked to interest conflicts between those who try to preserve their monopoly and those who try to acquire a new weapon either because of a threat or for reasons of regional prestige, the evolution from use to deterrence, the appearance of new actors after the USA and Russia, the role of nuclear tactical weapons, and the future of Russian weapons and know-how. He presents the international counter-proliferation context: the Non Proliferation Treaty (NPT), the IAEA and its controls, the Nuclear Supplier Group (NSG), the nuclear-free zones, the Comprehensive Test Ban Treaty (CTBT), the Missile Technology Control Regime (MTCR). He describes how and why proliferation occurs: uranium enrichment and plutonium technology, political reasons in different parts of the world. Then, he gives an overview of the proliferation status by commenting the cases of Israel, Iraq, India, Pakistan, North Korea, and Iran. He discusses the future of proliferation (involved countries, existence of a nuclear black market) and of counter-proliferation as far as Middle-East and North Korea are concerned. He tries finally to anticipate the consequences for nuclear deterrence strategy, and more particularly for Europe and France

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.

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.

The international right to health: state obligations and private actors in the health care system.

Science.gov (United States)

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.

Guess Where? Actor-Supervision for Spatiotemporal Action Localization

KAUST Repository

Escorcia, Victor

2018-04-05

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 Nuclear Question. After Iran: Toward Nuclear Proliferation in the Middle East?

International Nuclear Information System (INIS)

Courmont, Barthelemy

2008-01-01

Iran's potential acquirement of the atomic bomb could lead to nuclear proliferation in the Middle East. Many countries in the region would be tempted to follow the Iranian example, in order to maintain their regional power. This development could produce significant geopolitical consequences in a region where relationships are already tense. In this context, one can envisage different crisis scenarios: support for terrorist acts, attacks on American bases in the region, threats against the state of Israel. Accelerated nuclear proliferation in the Middle East would also jeopardize the efforts undertaken by regional actors during the past four decades to create a Nuclear Weapon Free Zone (NWFZ)

Limiting Future Proliferation and Security Risks

International Nuclear Information System (INIS)

Bari, R.

2011-01-01

A major new technical tool for evaluation of proliferation and security risks has emerged over the past decade as part the activities of the Generation IV International Forum. The tool has been developed by a consensus group from participating countries and organizations and is termed the Proliferation Resistance and Physical Protection (PR and PP) Evaluation Methodology. The methodology defines a set of challenges, analyzes system response to these challenges, and assesses outcomes. The challenges are the threats posed by potential actors (proliferant states or sub-national adversaries). It is of paramount importance in an evaluation to establish the objectives, capabilities, resources, and strategies of the adversary as well as the design and protection contexts. Technical and institutional characteristics are both used to evaluate the response of the system and to determine its resistance against proliferation threats and robustness against sabotage and terrorism threats. The outcomes of the system response are expressed in terms of a set of measures, which thereby define the PR and PP characteristics of the system. This paper summarizes results of applications of the methodology to nuclear energy systems including reprocessing facilities and large and small modular reactors. The use of the methodology in the design phase a facility will be discussed as it applies to future safeguards concepts.

Future non-proliferation challenges

International Nuclear Information System (INIS)

Yelchenko, Volodymyr

2008-01-01

Having chaired the Second Session of the Preparatory Committee Mr. Volodymyr Yelchenko noted that the NPT States parties reaffirmed the important role of the Treaty as the cornerstone of the global non-proliferation regime. They stressed that non-compliance with the Treaty provisions by States parties undermined non-proliferation and placed emphasis on the mutually reinforcing nature of disarmament and non-proliferation, and due respect for the right of States parties to the peaceful use of nuclear energy in conformity with the treaty. They reaffirmed the importance of promoting the peaceful uses of nuclear energy and international nuclear cooperation for peaceful purposes in ways consistent with the non-proliferation goal of the Treaty. The universality aspect was brought to the front with the lack of progress in this area. States parties called upon India, Israel and Pakistan to accede to the Treaty as non-nuclear-weapons states, promptly and without conditions and to bring into force comprehensive safeguards agreements, together with Additional Protocols, for ensuring non-proliferation. There is concern that non-States actors could gain access to weapons of mass destruction. One of the underlying themes at the Second Prepcom was the total elimination of nuclear weapons as the only absolute guarantee against their proliferation. Negative consequences to nuclear non-proliferation were also mentioned in the context of the abrogation of the Anti-Ballistic Missile Treaty and the development of missile defense systems, with the risk of a new arms race on Earth and in outer space. The importance of the immediate commencement of negotiations in the Conference of Disarmament on a treaty concerning fissile material for nuclear weapons or other nuclear explosive devices and the urgent conclusion of such a treaty as a beneficial step towards non-proliferation was stressed. The NPT states parties reaffirmed the role of the IAEA as the sole competent authority responsible for

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

Riding the Hype: The Role of State-Owned Enterprise Elite Actors in the Promotion of Jatropha in Indonesia

Directory of Open Access Journals (Sweden)

Deasy Simandjuntak

2014-06-01

Full Text Available Within a few years following its ambitious promotion in 2006, the development of jatropha in Indonesia came to a halt. Claimed as a potential solution to problems in energy and poverty, the introduction of jatropha in Indonesia’s energy policy had been triggered by the high oil prices in 2005. While studies by biofuel scholars have generally focused on what brought the end of the “miracle crop” hype by underlining various technical problems and the absence of market structure as the cause of its failure, few have examined jatropha as part of a policy-making trajectory, which began with, and was influenced by, the development narratives disseminated by individual actors. This article sheds light on the role of elite actors in the making of biofuel energy policy in Indonesia. Taking the case of the promotion of jatropha in 2005–2007, the article illustrates the role of the director of Indonesia’s leading sugar state-owned enterprise (SOE, Rajawali Nusantara Indonesia (RNI, whose decision in promoting jatropha became influential in forwarding its narratives into the national energy and development policy in 2006. In order to discover why a specific elite actor decided to promote jatropha, the article relies on data, including the SOE’s documents and interviews with key actor(s. The analysis is conducted using an actor-oriented approach, which underlines the discrepancy between the ideals and the operational practice of developmental goals.

This large report, notably based on interviews of many representatives of international institutions and politicians, ambassadors and researchers of different countries, all involved or specialized in nuclear and defence issues, starts with a description of the evolution of the international and geo-strategic context from the Cold War to a period of a new nuclear proliferation, with, in between, a period of stabilisation between the USA and the USSR. It also questions the various forms of proliferation which could be ballistic, biological, chemical, and cybernetic. Then, it analyses the role which mass destruction weapons have in international relationships, making a distinction between countries possessing such weapons (USA, Russia, China, France, Great-Britain), Israel which has been a newcomer for thirty years, the new actors (India, Pakistan, Iran, North Korea) with their own and different motivations, and the possible new actors (Libya, Syria). It comments the meaning of the ballistic threat and of the anti-missile defence. The third part of this report deals with the dissemination of proliferating technologies, describing the proliferation networks and the failure of actions against state-based proliferations, questioning the reality of the associated risks (discussion about the impact of September 11 attacks, about a chemical and biological terrorist threat which is realistic as well as difficult to be implemented, and about cybernetic attacks). The fourth part comments the impact of the international community on proliferation, outlining the different efficiencies of the international agreements and institutions (Chemical Weapons Convention, IAEA, Non Proliferation Treaty, Biological Weapons Convention, The Hague Code of Conduct), commenting the opportunities associated with other texts (those about nuclear free areas, or those produced by exporter groups), and discussing the attitude of the international community with respect to proliferation, and the

"Securing our survival (SOS": non-state actors and the campaign for a nuclear weapons convention through the prism of securitisation theory

Directory of Open Access Journals (Sweden)

Renata H. Dalaqua

2013-12-01

Full Text Available This article analyses the security practices of the anti-nuclear movement in the post-Cold War period through the prism of securitisation theory. By exploring Buzan and Wæver's conceptual developments on macrosecuritisations, the practices involved in the struggle against the Bomb are interpreted as securitising moves, in which the anti-nuclear movement is the leading securitiser. In the capacity of securitising actors, nuclear abolition activists argue that nuclear disarmament, under a Nuclear Weapons Convention (NWC, would be the only way to protect humankind from the threat posed by the existence of nuclear weapons. The empirical analysis of these non-state actors and their campaign for a NWC shows that, despite uttering security, the anti-nuclear movement has so far failed to achieve the proposed security measure, that is, nuclear disarmament. Nonetheless, securitisation has been instrumental for these non-state actors as a way of raising an issue on the agenda of decision-makers and urging them to take action.

An Autonomous Connectivity Restoration Algorithm Based on Finite State Machine for Wireless Sensor-Actor Networks

Directory of Open Access Journals (Sweden)

Ying Zhang

2018-01-01

Full Text Available With the development of autonomous unmanned intelligent systems, such as the unmanned boats, unmanned planes and autonomous underwater vehicles, studies on Wireless Sensor-Actor Networks (WSANs have attracted more attention. Network connectivity algorithms play an important role in data exchange, collaborative detection and information fusion. Due to the harsh application environment, abnormal nodes often appear, and the network connectivity will be prone to be lost. Network self-healing mechanisms have become critical for these systems. In order to decrease the movement overhead of the sensor-actor nodes, an autonomous connectivity restoration algorithm based on finite state machine is proposed. The idea is to identify whether a node is a critical node by using a finite state machine, and update the connected dominating set in a timely way. If an abnormal node is a critical node, the nearest non-critical node will be relocated to replace the abnormal node. In the case of multiple node abnormality, a regional network restoration algorithm is introduced. It is designed to reduce the overhead of node movements while restoration happens. Simulation results indicate the proposed algorithm has better performance on the total moving distance and the number of total relocated nodes compared with some other representative restoration algorithms.

Deconstructing Civil Society Actors and Functions: On the Limitations of International Frameworks for Fragile States

Directory of Open Access Journals (Sweden)

Simone Datzberger

2018-02-01

Full Text Available Over the past three decades, there has been a steady increase of funds by the international community to support civil society organizations (CSOs in fragile states. Surprisingly, this growing attention has not strengthened local civil society landscapes in a way that it would lead to processes of social transformation. On the contrary, civic freedom and space is shrinking around the globe. In analyzing prominent international aid-effectiveness frameworks and donor strategies towards civil society, this paper will put forward one central argument. The way in which civil society actors and functions are currently appropriated threatens deep-rooted social transformation thereby impeding processes of structural and political change—necessary for the transition from conflict to sustainable peace. In delineating, how actors and functional approaches informed peacebuilding and development policy and practice, their strengths and limitations will be examined. Doing so, we draw on different case studies and examples from the literature. We find that existing frameworks for fragile states operate on a presumed model of a public sphere and civil society that may or may not exist. Such an approach disregards an organic formation of a civil society landscape thereby impeding processes of structural, social, and political change in times of fragility.

With the development of autonomous unmanned intelligent systems, such as the unmanned boats, unmanned planes and autonomous underwater vehicles, studies on Wireless Sensor-Actor Networks (WSANs) have attracted more attention. Network connectivity algorithms play an important role in data exchange, collaborative detection and information fusion. Due to the harsh application environment, abnormal nodes often appear, and the network connectivity will be prone to be lost. Network self-healing mechanisms have become critical for these systems. In order to decrease the movement overhead of the sensor-actor nodes, an autonomous connectivity restoration algorithm based on finite state machine is proposed. The idea is to identify whether a node is a critical node by using a finite state machine, and update the connected dominating set in a timely way. If an abnormal node is a critical node, the nearest non-critical node will be relocated to replace the abnormal node. In the case of multiple node abnormality, a regional network restoration algorithm is introduced. It is designed to reduce the overhead of node movements while restoration happens. Simulation results indicate the proposed algorithm has better performance on the total moving distance and the number of total relocated nodes compared with some other representative restoration algorithms.

The EU and non proliferation: need for a quantum leap?

International Nuclear Information System (INIS)

Kobia, R.

2008-01-01

This paper analyses the possibilities of a strategy and all-encompassing European policy that could constitute an efficient and structured system against proliferation. This paper concentrate on actions and developments at the level of the E.U. sensu stricto, i.e. where common actions under the E.U. umbrella are set up and contribute to the efforts in non-proliferation. It does not cover all measures and mechanisms under the 'non-proliferation regime', the integrated and evolving network of unilateral, bilateral, regional, multilateral treaties and other standing-setting arrangements, which collectively provide a framework guiding the behaviour of states, international organisations, enterprises, associations and all non state actors generally active in the nuclear sector. For the purposes of this paper, the 'utilitarian and teleological' prisms are used. The 'utilitarian perspective aims to maximizing the net expectable utility for all parties affected by a decision or action knowing the that traditional utilitarianism favours the options that bring about the best consequences and aims at the 'good'. The teleological approach lies in an interpretation that favours the ultimate goals of any provision and action as well as their spirit, rather than accepting to remain in a more narrow exegetic interpretation that favours the strict letter thereof.

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.

The technical potential for proliferation in Northeast Asian states

International Nuclear Information System (INIS)

Joeck, N.; Kramer, R.

1995-01-01

This is a review of the technical capabilities of the states in Northeast Asia - principally Japan, South Korea, and North Korea - to develop nuclear weapons. At the outset, however, it should be emphasised that nuclear proliferation is primarily a political and security problem, rather than a technical challenge. The technical challenge is substantial, but if one looks at states with the technical capacity to develop nuclear weapons, it might be surprising to find that most of them have chosen not to do so. Even with access to fissile material and the technical and scientific infrastructure necessary to produce nuclear weapons, such states as Canada, Switzerland, Norway, Germany, Argentina, Brazil, Japan and many others, have not done so. All three non-nuclear weapon states in Northeast Asia have the technical capability to develop nuclear weapons. Japan and South Korea have intrusive safeguards and inspection arrangements on their nuclear programs, which allow their neighbours and the rest of the world to verify that they have not changed that status, and that they are living up to their NPT commitments. Despite its original commitment to the NPT, North Korea has yet to establish similar arrangements. It is ironic that the country with the smallest and technically least sophisticated nuclear program is the one creating the greatest concern about nuclear proliferation in the region. This irony illustrates the point made in the introduction, however. Nuclear proliferation is more a function of political decision-making than of technical capability

Two-actor conflict with time delay: A dynamical model

Science.gov (United States)

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.

Self-Recovering Sensor-Actor Networks

Directory of Open Access Journals (Sweden)

Maryam Kamali

2010-07-01

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.

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.

'For good and for bad': the relations between universal obligations and particular efforts in the field of nuclear non-proliferation

Dassen Van, L.

2005-01-01

Full text: The world has 'nuclear non-proliferation' on its lips. Presidents, politicians, journalists and others refer to it as the number one peril in our times. This may be right or wrong but irrespective of the real salience of 'nuclear dangers' it has a grip on our minds and wallets. A long range of states now make active investments in the improvement of nuclear security; not only at home as they used to do, but even abroad in other places and countries where there is concern with regard to how safe nuclear and materials are kept and stored. This development is surely an expression of a shared broadening of our sense of responsibility beyond the narrow confines of statehood and borders, and therefore this development should please us. On the other hand, the truly universal measures and instruments of the NPT and the regime round it are in trouble. It is being stated in some quarters that the NPT is inadequate in a new era with new threats from sub-state actors. Nevertheless, the NPT is the only legal instrument that is a framework that either by itself or as a starting-point can serve as a tool box for long-term storage of the proliferation risks. The reason for this is that the NPT is an expression of fairness in terms of rights and balances for all states committed to non-proliferation. And its foundations are those of international law. To the extent the NPT is being questioned will there also be a risk that non-proliferation efforts in the framework of cooperative threat reduction and for instance global partnership will lose legitimacy; simply for the reason that only a small number of the non-proliferation concerns are given attention. This relationship between cooperative threat reduction efforts on the one hand and universal legal instruments for non-proliferation on the other is a double-edged sword. While the two can reinvigorate and strengthen each other, there is also a risk that the one - cooperative threat reduction - when given preference over

Assessing the optimism-pessimism debate: Nuclear proliferation, nuclear risks, and theories of state action

International Nuclear Information System (INIS)

Busch, Nathan Edward

2001-01-01

This dissertation focuses on the current debate in international relations literature over the risks associated with the proliferation of nuclear weapons. On this subject, IR scholars are divided into roughly two schools: proliferation 'optimists,' who argue that proliferation can be beneficial and that its associated hazards are at least surmountable, and proliferation 'pessimists,' who believe the opposite. This debate centers upon a theoretical disagreement about how best to explain and predict the behavior of states. Optimists generally ground their arguments on rational deterrence theory and maintain that nuclear weapons can actually increase stability among states, while pessimists often ground their arguments on 'organization theory,' which contends that organizational, bureaucratic, and other factors prevent states from acting rationally. A major difficulty with the proliferation debate, however, is that both sides tend to advance their respective theoretical positions without adequately supporting them with solid empirical evidence. This dissertation detailed analyses of the nuclear programs in the United States, Russia, China, India, and Pakistan to determine whether countries with nuclear weapons have adequate controls over their nuclear arsenals and tissue material stockpiles (such as highly enriched uranium and plutonium). These case studies identify the strengths and weaknesses of different systems of nuclear controls and help predict what types of controls proliferating states are likely to employ. On the basis of the evidence gathered from these cases, this dissertation concludes that a further spread of nuclear weapons would tend to have seriously negative effects on international stability by increasing risks of accidental, unauthorized, or inadvertent use of nuclear weapons and risks of thefts of fissile materials for use in nuclear or radiological devices by aspiring nuclear states or terrorist groups.

Tatiana Coutto

2013-04-01

Full Text Available This article focuses on the role of regional institutions and political practices in strengthening multilateral disarmament and non-proliferation regimes. Particular attention is devoted to coordination between Brazil and Argentina with a view to forging a "South American position" vis-à-vis the Biological and Toxins Weapons Convention (BTWC. Empirical evidence suggests that informal arrangements between the two countries were capable of involving other South American leaders and promoting the exchange of information among different groups of states, most notably during the 2006 BTWC review conference. This paper also sheds light on the identification of specific features that allow for increasing visibility and actorness of regional powers in promoting universality of multilateral security regimes (MSR, as well as the limitations faced by these players.

The effect of cerium valence states at cerium oxide nanoparticle surfaces on cell proliferation

KAUST Repository

Naganuma, Tamaki

2014-05-01

Understanding and controlling cell proliferation on biomaterial surfaces is critical for scaffold/artificial-niche design in tissue engineering. The mechanism by which underlying integrin ligates with functionalized biomaterials to induce cell proliferation is still not completely understood. In this study, poly-l-lactide (PL) scaffold surfaces were functionalized using layers of cerium oxide nanoparticles (CNPs), which have recently attracted attention for use in therapeutic application due to their catalytic ability of Ce4+ and Ce3+ sites. To isolate the influence of Ce valance states of CNPs on cell proliferation, human mesenchymal stem cells (hMSCs) and osteoblast-like cells (MG63) were cultured on the PL/CNP surfaces with dominant Ce4+ and Ce3+ regions. Despite cell type (hMSCs and MG63 cells), different surface features of Ce4+ and Ce3+ regions clearly promoted and inhibited cell spreading, migration and adhesion behavior, resulting in rapid and slow cell proliferation, respectively. Cell proliferation results of various modified CNPs with different surface charge and hydrophobicity/hydrophilicity, indicate that Ce valence states closely correlated with the specific cell morphologies and cell-material interactions that trigger cell proliferation. This finding suggests that the cell-material interactions, which influence cell proliferation, may be controlled by introduction of metal elements with different valence states onto the biomaterial surface. © 2014 Elsevier Ltd.

Proposal for Requirement Validation Criteria and Method Based on Actor Interaction

Science.gov (United States)

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.

Soft Power in Central Asia: Actors and Its Activities

2014-01-01

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.

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.

Methodology Development and Applications of Proliferation Resistance and Physical Protection Evaluation

International Nuclear Information System (INIS)

Bari, R.A.; Peterson, P.F.; Therios, I.U.; Whitlock, J.J.

2010-01-01

We present an overview of the program on the evaluation methodology for proliferation resistance and physical protection (PR and PP) of advanced nuclear energy systems (NESs) sponsored by the Generation IV International Forum (GIF). For a proposed NES design, the methodology defines a set of challenges, analyzes system response to these challenges, and assesses outcomes. The challenges to the NES are the threats posed by potential actors (proliferant States or sub-national adversaries). The characteristics of Generation IV systems, both technical and institutional, are used to evaluate the response of the system and to determine its resistance against proliferation threats and robustness against sabotage and terrorism threats. The outcomes of the system response are expressed in terms of a set of measures, which are the high-level PR and PP characteristics of the NES. The methodology is organized to allow evaluations to be performed at the earliest stages of system design and to become more detailed and more representative as the design progresses. It can thus be used to enable a program in safeguards by design or to enhance the conceptual design process of an NES with regard to intrinsic features for PR and PP.

Exploring Agreements of Convenience Made among Violent Non-State Actors

Annette Idler

2012-10-01

Full Text Available This article aims to enhance our understanding of how different groups of violent non-state actors (VNSAs interact. It narrows the conceptual gap that has existed in the literature on VNSAs and the complex and multiple types of relationships that exist among them in order to better comprehend their decision-making and the ramifications that emerge from these decisions and interactions. Drawing on recent field research in Colombia´s border regions, the study develops a typology of VNSA interactions, conceptualised as a two-dimensional “clustery continuum” of VNSA arrangements. These borderlands lend themselves to such an undertaking because different types of VNSAs are present there and they unite an internal armed conflict context with a non-conflict, yet violent context by comprising both the Colombian and the neighbouring countries’ border zones. Taking a holistic and nuanced approach, this article first links the silos of civil war, mafia and organised crime literature by exploring situations in which these different dynamics coalesce. Second, it assumes a transnational perspective rather than a purely national view by considering borderlands that include territory of various states. Third, it unpacks the different types of VNSA interactions by describing them as based largely on economically motivated “arrangements of convenience”, rather than drawing on a dichotomy of conflict and cooperation. This case study yields insights on how to develop a more sophisticated understanding of VNSA interactions in other contexts as well. 

North Korea: a mercenary proliferator?

International Nuclear Information System (INIS)

Hemez, Remy

2015-01-01

After having recalled that North Korea possesses a rather advanced ballistic programme which has been started in the 1970 with the Chinese support, that North Korea is the fourth world producer of ballistic missiles, the author outlines that this country has become a major proliferator as it exports this production to different States and non-State actors. He recalls the long history of relationships between North Korea and terrorist organisations (even during the Cold War), comments the current and major support of North Korea to Hamas and Hezbollah in Gaza and in Lebanon. These relationships are then related with those these both organisations have with Syria and Iran who are in fact the relays between them and North Korea. The author explains why Hamas and Hezbollah must buy their weapons to such a far country: Iran is submitted to international sanctions, Iran and Syria want to avoid being banned from the international community for selling weapon to a terrorist (or so-said) organisation, and prices are rather competitive. If North Korea is also submitted to international sanctions, weapon smuggling seems to be institutional in this country. The author finally briefly evokes the issue of chemical weapons: North Korea possesses few thousand tonnes of these weapons, and could export them to non-state organisations

APPROACHES TO GLOBAL SECURITY. ACTORS, MANIFESTATIONS AND TENDENCIES

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.

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.

World Health Organization and the search for accountability: a critical analysis of the new framework of engagement with non-state actors.

Science.gov (United States)

Rached, Danielle Hanna; Ventura, Deisy de Freitas Lima

2017-07-03

The article probes the origins and content of the Framework of Engagement with Non-State Actors (FENSA) of the World Health Organization (WHO), approved on May 28, 2016, at the 69th World Health Assembly, which established different rules of collaboration to four categories of actors: nongovernmental organizations (NGOs), private sector entities, philanthropic foundations, and academic institutions. Applying the findings of International Legal Theory and based on extensive documentary research, we sought to determine whether FENSA is an appropriate accountability mechanism according to four functions of accountability: constitutional, democratic, epistemic, and populist. The article concludes that there is a risk of the prevalence of the populist function at the expense of the accountability potential that could result from the better use of the other three accountability functions.

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.

World Health Organization and the search for accountability: a critical analysis of the new framework of engagement with non-state actors

Full Text Available The article probes the origins and content of the Framework of Engagement with Non-State Actors (FENSA of the World Health Organization (WHO, approved on May 28, 2016, at the 69th World Health Assembly, which established different rules of collaboration to four categories of actors: nongovernmental organizations (NGOs, private sector entities, philanthropic foundations, and academic institutions. Applying the findings of International Legal Theory and based on extensive documentary research, we sought to determine whether FENSA is an appropriate accountability mechanism according to four functions of accountability: constitutional, democratic, epistemic, and populist. The article concludes that there is a risk of the prevalence of the populist function at the expense of the accountability potential that could result from the better use of the other three accountability functions.

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

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.

United States non-proliferation policy

International Nuclear Information System (INIS)

Scheinman, L.

1978-01-01

U.S. non-proliferation policy is aimed at slowing the spread of nuclear weapons capabilities, managing the destabilizing effects of nuclear technology for energy purposes, and fostering international standards and institutions to deal responsibly with global nuclear development. These goals assume that nuclear technology has not already precluded social control and recognize the social benefits offered by peaceful uses of atomic energy. Non-proliferation policies recognize that the motivation for possessing nuclear weapons is a more-difficult problem than technical ability and will concentrate on reducing those incentives through international agreements and safeguards and by maintaining the separation of commercial nuclear fuel cycles and military uses

An important need in cancer research and treatment is a physiological means in vitro by which to assess the proliferation capacity of human tumors and corresponding normal tissue for comparison. The authors have recently developed a native-state, three-dimensional, gel-supported primary culture system that allows every type of human cancer to grow in vitro at more than 90% frequency, with maintenance of tissue architecture, tumor-stromal interaction, and differentiated functions. Here they demonstrate that the native-state culture system allows proliferation indices to be determined for all solid cancer types explanted directly from surgery into long-term culture. Normal tissues also proliferate readily in this system. The degree of resolution of measurement of cell proliferation by histological autoradiography within the cultured tissues is greatly enhanced with the use of epi-illumination polarization microscopy. The histological status of the cultured tissues can be assessed simultaneously with the proliferation status. Carcinomas generally have areas of high epithelial proliferation with quiescent stromal cells. Sarcomas have high proliferation of cells of mesenchymal organ. Normal tissues can also proliferate at high rates. An image analysis system has been developed to automate proliferation determination. The high-resolution physiological means described here to measure the proliferation capacity of tissues will be important in further understanding of the deregulation of cell proliferation in cancer as well as in cancer prognosis and treatment

Criminalizing WMD Proliferation: the Role of U.N. Security Council Resolution 1540

International Nuclear Information System (INIS)

Durbin, Karyn R.; Mladineo, Stephen V.; Vannoni, Michael G.

2005-01-01

The United Nations (U.N.) Security Council unanimously passed Resolution 1540 in April 2004. This landmark measure legally charges all U.N. Member States to enact and enforce effective measures to prevent the proliferation of weapons of mass destruction and their means of delivery by preventing illicit trafficking of chemical, biological, radiological, and nuclear (CBRN) materials and related technologies. Revelations regarding the expansiveness of the A.Q. Khan network provided a clear impetus for the Resolution. Resolution 1540 is distinctive because it is the first time the U.N. Security Council has required all Member States to act to prevent the illicit trafficking of CBRN materials and their means of delivery. It is also unique in that it specifically addresses prevention of CBRN proliferation and trafficking among non-state actors. The Resolution has a direct impact on the management of nuclear materials and nonproliferation policy in the future. Consequently, the INMM Nonproliferation and Arms Control Technical Division and the INMM Northeast Chapter initiated a professional workshop on March 15, 2005 to engage topical experts in a discussion of U.N. Security Council Resolution 1540. Although Resolution 1540 is now one year old and the Committee established to monitor its implementation has begun its work, many in the nonproliferation and nuclear materials management communities have not learned of the Resolution or have not yet recognized its significance. This article provides a summary of and perspectives on the workshop discussion that was conducted on a not-for-attribution basis

Actors of Columbian drug trade : development and transformation

2011-06-01

Full Text Available The aim of this article is to portray the main shifts which have been taking place in Colombian drug scene since the 70’s up to the present especially in relation to actors of this business and form of their activity. At first the development of Colombian drug trade till the 80’s when two big cartels centered in Medellín and Cali arose will be briefly outlined. These cartels were able to control a great part of domestic drug trade and due to their enormous power represented serious threat to Colombian state. Thus the cartels declared open warfare with the state in the 80’s. After the cartels’ elimination in the middle of 90’s new actors represented by small drug organizations arose in Colombian drug scene. These small groups were dependent upon cooperation with foreign partners, especially with Mexican cartels. Ever more important role in drug business is played by Colombian left-wing guerilla groups which will be described in the next part of the article. The problem of right-wing paramilitary groups and their participation in Colombian drug trade will be mentioned as well.

The Third Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons will be held in Geneva, Switzerland, in 1985 with a view to assuring that the purposes and provisions of the Treaty are being realized. The Treaty, commonly referred to as the non-proliferation Treaty, is the fundamental instrument to avert the danger of proliferation of nuclear weapons and is, perhaps, the most important multilateral arms regulation agreement of our time. It was negotiated in the 1960s in the Eighteen-Nation Committee on Disarmament in Geneva and in the United Nations General Assembly. The Treaty was opened for signature in London, Moscow and Washington on July 1, 1968. On that date, it was signed by the three Depositary Governments - the Soviet Union, the United Kingdom and the United States - and by 58 other States. As of December 31, 1983 the number of States parties to the Treaty had risen to 119

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.

Multi-actor governance of sustainable biofuels in developing countries: The case of Mozambique

International Nuclear Information System (INIS)

Schut, Marc; Cunha Soares, Núria; Ven, Gerrie van de; Slingerland, Maja

2014-01-01

This paper describes and analyses the multi-actor governance process that made Mozambique the first African nation-state to develop a national policy framework for sustainable biofuels. The paper draws on findings from action research conducted in Mozambique between December 2008 and July 2012. We analyse interactions between the changing governance context, the course of the multi-actor governance process, and the choices in relation to governance framework characteristics and content for four successive stages of governance framework development. This provides the basis for reflection on the competences required for effective multi-actor sustainability governance, and a discussion about the role of the nation-state in sustainability governance of global economies such as biofuels. The governance framework for sustainable biofuels has contributed to a more transparent and secure investment climate for biofuels in Mozambique. Key factors for success were (1) the presence of different types of competences during the various stages of the governance framework development, (2) closing the gap between ‘licences to sell’ and ‘licences to produce’ across different governance levels, and (3) balancing between the short- and long-term objectives for biofuel production in Mozambique and requirements of global biofuel markets. Developing-country nation-states can provide an essential contribution to these success-factors for global governance of sustainable biofuels. - Highlights: • Mozambique is the first African country that developed a national governance framework for sustainable biofuels. • Independence, representation, expertise and operational capacity are essential competences in multi-actor sustainability governance. • Developing country's nation-states play an essential role in harmonizing short- and long-term objectives across different governance levels. • Synergies between licences to sell and licences to produce biofuels sustainably should

A Low-cost System for Generating Near-realistic Virtual Actors

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.

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

Science.gov (United States)

Wendt, Claus; Agartan, Tuba I; Kaminska, Monika Ewa

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.

The Non-Proliferation Treaty of Nuclear Weapons (NPT) and the insertion of the Brazilian State in its regime

International Nuclear Information System (INIS)

Silva, Marcos Valle Machado da

2010-01-01

The issue of nuclear weapons continues to appear as a focal point of International Relations. The efforts and concrete actions on disarmament, non-proliferation, and nuclear arms control are still issues that generate recurring tensions between States. However, in Brazil, there is little analysis of an academic nature about these issues and, with respect to current and prospective position of the Brazilian State in the Nuclear Weapons Non- Proliferation Regime, studies and analysis are even more scarce, or incipient. The present dissertation has as its object of study to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), the Regime arisen from NPT, and the Brazilian State insertion process in this Regime. Therefore our research work is structured in three areas: the first one is about the role of nuclear weapons in States security perception, the second is about NPT and its Regime, the third runs over the insertion of the Brazilian state in this regime. So, in summary, the research performed included the reasons that make a State to develop nuclear weapons, the NPT genesis and evolution of the perception of the meaning of that Treaty by the States, and the process and the degree of insertion of Brazil in the Nuclear Weapons Non- Proliferation Regime. The inquiry sought to place this object of study in the broader debate on Foreign Relations, based on the approaches of the discipline devoted to the question of managing the security of States, id est, the two approaches that constitute the mainstream of the discipline: the perspective theoretical liberal (and neoliberal variants) and realistic thinking (and neo-realist). Thus, we have used different theoretical lenses, which we think necessary for understanding the specific parts and causal connections between these parts of a complex issue. (author)

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

Actors' portrayals of depression to test interrater reliability in clinical trials.

2004-10-01

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.

Compositional schedulability analysis of real-time actor-based systems.

Jaghoori, Mohammad Mahdi; de Boer, Frank; Longuet, Delphine; Chothia, Tom; Sirjani, Marjan

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.

Perspectives of the nuclear non-proliferation regime

International Nuclear Information System (INIS)

Koungou, Leon

2004-01-01

To join traditional methods and new approaches of 'non-proliferation'. This is a technical method and the best way to fight against 'non-proliferation' which is facing few preoccupations: knowledge's disseminations; technologies; equipments and weapons that should be stopped. As it's important to note the return of nuclear danger as the end of confrontation between west-east which should be reduce. As the adaptation of mechanisms is necessary today, as it is important to react about states' incitations to violate international engagement of non-proliferation. Areas control allows finding out change and evolution, but more insufficient. Functional difficulties show that the IAEA (International Agency of Atomic Energy) does not work good. Safeguard system does not allow to respect 'non-proliferation' engagements; for instance 'junkies states' that they cannot dissuade traditional methods. The fight of 'non-proliferation' shows new progresses with fearing methods of prevention actions and heaviest international controls of exportation. The target of this is very ambitious. This new method is self-successful because it contributes to re-enforce international security when defeating acquisition of nuclear and mass destruction weapons by non-states factors. Therefore non-proliferation regime and especially 'non-proliferation treaty' remains delicate as long as some militaries state such USA will reject their 'non-proliferation' engagement. (author) [fr

An Actor and His Suitcase

OpenAIRE

Williams, Maurice

2013-01-01

The idea of the actor as journeyman is as old as the profession itself. The travel troupes of yesteryear laid the groundwork for the theatres of Shakespeare and the regional theatre circuit here in America. So if there is one thing an actor must have: it's a good suitcase. Or two. One for the rags and trinkets he, or she, holds dear; and another for all the skills he, or she, brings to every project.When I left the east coast for San Diego I brought with me those two suitcases. Luckily for me...

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.

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.

1968 en América Latina: aparición de nuevos actores

Full Text Available Más allá de reivindicaciones y protestas semejantes a las que se desarrollan en Europa y en el mundo, el año 1968 en América Latina se caracteriza por la aparición de nuevos actores (jóvenes, clases medias, feminismo, Iglesia, sindicatos. Los nuevos actores tienden a ocupar el hueco dejado por actores tradicionales que, en el seno de sociedades debilitadas por la crisis económica, ya no consiguen desempeñar su papel de actores democráticos. La organización de las Olimpiadas en México y la visita papal en Colombia prueban hasta qué punto la región es integrada al mundo moderno. Pero en México como en Argentina la prepotencia de gobiernos que se niegan al diálogo provoca choques violentos. 1968 está también marcado por opciones represivas que anuncian la acción violenta de los estados terroristas que 5 años más tarde conquistarán el poder mediante golpes de estado.____________________ABSTRACT:More than just voicing demands and protestations similar to those heard in Europe and around the world, the Americas in 1968 were mainly characterized by new articulate social groups (young people, middle class, feminists, church, trade-unions forefront. Within societies affected by an economic crisis, theses new social actors emerged upon a scene abandoned by other groups who, due to economical crisis, were no longer able or willing to take on their democratic duty. The choice of Mexico for the Olympic Games and the Pope's visit to Colombia are certainly evidence that Latin America was now integrated to the modern world. In Mexico and Argentina, however, authoritarian governments turned a deaf ear to demands put forth by their citizens thus creating a climate of social violence and upheaval. In 1968, an increase in repression as the sole response by the State, announced the brutality that future terrorist governments were soon to practise from 1973 on when the military juntas took over state control through putsches.

Rosana GARCIANDÍA GARMENDIA

2012-06-01

Full Text Available During the last decade, many reforms took place in the European Union legal and policy framework. Some of those reforms were motivated by the participation of the European Union and its member States in the World Trade Organization. This paper aims to analyze the role of the European Union as an actor in that organization, paying special attention to its mixed legal nature – EU and Member States. With that purpose, the evolution of the relationship between the EU member States and the EU itself as simultaneous actors at the WTO is studied. The division of competences is also reviewed. Finally, the analysis of the EU position in different negotiation rounds (Uruguay, Doha for the agricultural sector is reviewed as an example of the evolution in the protection of European interests. The paper shows that some changes in the Treaty of Lisbon have strengthened the legal framework for the EU to be heard with a unique voice in the WTO

We consider the actor-critic contextual bandit for the mobile health (mHealth) intervention. State-of-the-art decision-making algorithms generally ignore the outliers in the dataset. In this paper, we propose a novel robust contextual bandit method for the mHealth. It can achieve the conflicting goal of reducing the influence of outliers while seeking for a similar solution compared with the state-of-the-art contextual bandit methods on the datasets without outliers.

Efficient model learning methods for actor-critic control.

Science.gov (United States)

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.

The USA and proliferation in Northeast Asia

International Nuclear Information System (INIS)

Weeks, S.B.

1995-01-01

United States policy on proliferation in Northeast Asia poses a test of balance between general US global non-proliferation goals and specific US regional security goals for Northeast Asia. US policy on proliferation in Northeast Asia further poses a test of priorities for US bilateral relations with the key Northeast Asian states, as non-proliferation and regional security goals must be weighed against other (e.g., economic, human rights) declared US policy goals. The result is a US policy equation for Northeast Asia proliferation that is considerably more complex in execution than might be expected from the simple statement of the US goal to avoid nuclear proliferation in Northeast Asia. The question of security assurances - both negative and positive - may be closely related to US policies to avoid proliferation in Northeast Asia

Intelligence and Nuclear Proliferation: Lessons Learned

International Nuclear Information System (INIS)

Hansen, Keith A.

2011-09-01

Intelligence agencies play a fundamental role in the prevention of nuclear proliferation, as they help to understand other countries' intentions and assess their technical capabilities and the nature of their nuclear activities. The challenges in this area remain, however, formidable. Past experiences and the discoveries of Iraq's WMD programs, of North Korean nuclear weapon program, and of Iranian activities, have put into question the ability of intelligence to monitor small, clandestine proliferation activities from either states or non-state entities. This Proliferation Paper analyzes the complex challenges intelligence faces and the various roles it plays in supporting national and international nuclear non-proliferation efforts, and reviews its track record. In an effort to shed light on the role and contribution of intelligence in national and international efforts to halt, if not prevent, further nuclear weapon proliferation, this paper first analyzes the challenges intelligence faces in monitoring small, clandestine proliferation activities and the role it plays in supporting non-proliferation efforts. It then reviews the intelligence track record in monitoring proliferation including the lessons learned from Iraq. Finally, it addresses whether it is possible for intelligence to accurately monitor future clandestine proliferation efforts. (author)

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

Science.gov (United States)

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.

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.

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

Science.gov (United States)

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.

American Long-Distance Locomobility and the Spaces of Actor-Network Theory

Directory of Open Access Journals (Sweden)

Michael Minn

2016-03-01

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.

Innovation in the plural of the alpine cre-actors

Andréa Finger-Stich

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.

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.

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

2008-01-01

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.

This issue of the ANNALS addresses itself to three aspects of nuclear proliferation: the prospect that new nuclear powers will come on the scene, the problems that their arrival may create, and ways of coping with those problems. In an introductory paper, ''Quo Vadimus,'' Joseph I. Coffey investigates the pros and cons of proliferation, concluding that it is not a question of whether there will be nuclear proliferation, but in what countries. Part I, Where We Are, contains five papers preceded by introductory comments by Joseph I. Coffey. The papers and their authors are: Why States Go--and Don't Go--Nuclear, William Epstein; How States Can ''Go Nuclear,'' Frank C. Barnaby; What Happens If. . .Terrorists, Revolutionaries, and Nuclear Weapons, David Kreiger; Safeguards Against Diversion of Nuclear Material: An Overview, Ryukichi Imai; and Reducing the Incentives to Proliferation, George H. Quester. Part II, And Where We May Go, again includes some introductory remarks by Joseph I. Coffey. The seven succeeding papers are: Nth Powers of the Future, Ashok Kapur; Nuclear Proliferation and World Politics, Lewis A. Dunn; Arms Control in a Nuclear Armed World, Colin Gray; The United Nations, the Superpowers, and Proliferation, Abraham Bargman; Proliferation and the Future: Destruction or Transformation, Frederick C.

EL ROL DE LOS ACTORES SOCIALES EN LA CONFIGURACIÓN TERRITORIAL DE MOQUEHUE

2017-12-01

Full Text Available Moquehue is a small mountain settlement located in Aluminé department, Neuquén, Argentina. It aroses in the 40's, as a product of the development of cattle raising and forestation. Since these activities began, the permanent settlement and first commercial activities appeared, in order to cover the new demands. Nature has given the region a beautiful landscape that acquires value since the 70's, when the population of nearby localities began to usufruct tourism in the region. Even though the lands belong to the Provincial State, since 1984 they are under the control of the Pulmarí Interstate Corporation (PIC, which regulates their use. In 1980, tourism was stimulated by state politics that lead to the growth and expansion of Villa Pehuenia and Moquehue, defining a new territorial configuration, in which different social actors have an active role. In the last decade, this dynamism was accentuated in Moquehue, a zone without regulation of the occupation and in an area with limited provision of services. The objective of this paper was the analysis of territorial transformations promoted by social actors that established the current uses of the land and its environmental consequences, considering the role of municipal and provincial government in these transformations. Research includes compilation of information, interviews and field survey of new occupations. This information was digitized. Four relevant social actors are recognized in the development and growth of Moquehue, linked especially to tourism activity: the municipality, that defines parcels for permanent residential use and services; private actors, that increase accommodation supply; historical local people who subdivide and sell land irregularly, and new actors who settle in the area with permanent residence, linked to other activities that made them choose this place because of its environmental values. As a result, zones with different types of transformation are identified, in

Electrophysiological difference between mental state decoding and mental state reasoning.

Previous studies have explored the neural mechanism of Theory of Mind (ToM), but the neural correlates of its two components, mental state decoding and mental state reasoning, remain unclear. In the present study, participants were presented with various photographs, showing an actor looking at 1 of 2 objects, either with a happy or an unhappy expression. They were asked to either decode the emotion of the actor (mental state decoding task), predict which object would be chosen by the actor (mental state reasoning task), or judge at which object the actor was gazing (physical task), while scalp potentials were recorded. Results showed that (1) the reasoning task elicited an earlier N2 peak than the decoding task did over the prefrontal scalp sites; and (2) during the late positive component (240-440 ms), the reasoning task elicited a more positive deflection than the other two tasks did at the prefrontal scalp sites. In addition, neither the decoding task nor the reasoning task has no left/right hemisphere difference. These findings imply that mental state reasoning differs from mental state decoding early (210 ms) after stimulus onset, and that the prefrontal lobe is the neural basis of mental state reasoning.

The inhibition of tumor-cell proliferationbyan organicsolvent extract from the solid-state fermentation of Phellinus baumii mycelia inoculated in rice medium was investigated in vitro. The active compounds inhibiting tumor-cell proliferation were characterized. Results revealed that all (petroleum ether, chloroform, ethyl acetate, and butanol) fractions inhibited tumor-cell proliferation in a dose-dependent fashion. The ethyl acetate extract had the highest inhibitory effecton tumor-cell proliferation, and the butanol fraction had the lowest. Six compounds were isolated and purified from the ethyl acetate extract of P. baumii mycelia by the tandem application of silica-gel column chromatography (SGCC), high-speed countercurrent chromatography (HSCCC), and preparative HPLC. These compounds were identified by NMR and electrospray ionization-mass spectrometry (ESI-MS) spectroscopic methods as ergosterol (RF1), ergosta-7,22-dien-3β-yl pentadecanoate (RF3), 3,4-dihydroxy benzaldehyde(RF6), inoscavinA (RF7), baicalein(RF10), and 24-ethylcholesta-5,22-dien-3β-ol (RF13). To further clarify the activity of these compounds, the cell-proliferation-inhibition tests of these compounds on various tumor cells were carried out and evaluatedin vitro. Results suggested that compounds RF6, RF7, and RF10 had potent inhibition effects on the proliferation of a series of tumor cell lines, including K562, L1210, SW620, HepG2, LNCaP, and MCF-7cells.

Full Text Available The inhibition of tumor-cell proliferationbyan organicsolvent extract from the solid-state fermentation of Phellinus baumii mycelia inoculated in rice medium was investigated in vitro. The active compounds inhibiting tumor-cell proliferation were characterized. Results revealed that all (petroleum ether, chloroform, ethyl acetate, and butanol fractions inhibited tumor-cell proliferation in a dose-dependent fashion. The ethyl acetate extract had the highest inhibitory effecton tumor-cell proliferation, and the butanol fraction had the lowest. Six compounds were isolated and purified from the ethyl acetate extract of P. baumii mycelia by the tandem application of silica-gel column chromatography (SGCC, high-speed countercurrent chromatography (HSCCC, and preparative HPLC. These compounds were identified by NMR and electrospray ionization-mass spectrometry (ESI-MS spectroscopic methods as ergosterol (RF1, ergosta-7,22-dien-3β-yl pentadecanoate (RF3, 3,4-dihydroxy benzaldehyde(RF6, inoscavinA (RF7, baicalein(RF10, and 24-ethylcholesta-5,22-dien-3β-ol (RF13. To further clarify the activity of these compounds, the cell-proliferation-inhibition tests of these compounds on various tumor cells were carried out and evaluatedin vitro. Results suggested that compounds RF6, RF7, and RF10 had potent inhibition effects on the proliferation of a series of tumor cell lines, including K562, L1210, SW620, HepG2, LNCaP, and MCF-7cells. These findings indicated that P. baumii mycelia produced by solid-state fermentation in rice canbe used to obtain active compounds with the ability to inhibittumor-cell proliferation.

The Establishment of Marine Protected Areas in Senegal: Untangling the Interactions Between International Institutions and National Actors

Ferraro, Gianluca; Brans, Marleen; Dème, Moustapha; Failler, Pierre

2011-04-01

International institutions, understood as sets of rules contained in international agreements, are aimed at orienting national governments towards specific policy options. Nevertheless, they can determine a change in national policies and practices only if states are willing and capable of incorporating international obligations into their national legislations and ensuring their application and enforcement in areas that follow completely under national jurisdiction. The establishment of marine protected areas promoted by international agreements as a tool for the protection of marine resources represents an interesting case for revealing the complex interactions between international institutions and national actors. Particularly, the establishment of these areas in Senegal shows the salience of domestic constellations of actors who may support or undercut national commitments to international regimes: political elites, bureaucracies, the general public and target groups. By anchoring the empirical analysis to an actor-centred institutionalist perspective, the article explains how dynamic constellations of actors can distort the penetration of international objectives in the national policy framework. Different constellations of national actors can indeed bend international institutions at different moments: during the formulation of a new law in line with international obligations; in the definition of its implementation framework; and in the enforcement of national policies.

2014-08-01

Full Text Available In the article on the memoirs and archival material basis of Central State Historical Archives of Ukraine, Kyiv and State Archives of Kharkiv Region the etymology of some actor’s pseudonyms on the Dnieper Ukraine territory in late XIX – early XX century was analysed. The pseudonyms’ place and role in desired professional actor image formation were determined. In particular the fact that pseudonyms borrowed or transformed from the famous literary character names used to transfer the character’s moral qualities and exterior to the artist was defined. The stage name creation specificity depending on the affiliation of the actor to the Russian or Ukrainian repertoire was shown. Also the basic motives for fictional anthroponym using in actors’ society were depicted. The main reason for the actor’s name-change among ones originated from the nobility and clergy was shown. Besides the recognition of pseudonym as the important part of professional success not only among the actors, but also among entrepreneurs of Dnieper Ukraine in late XIX – early XX century was explored.

TACKLING THE INFORMAL ECONOMY IN THE EUROPEAN UNION: A SOCIAL ACTOR APPROACH

Directory of Open Access Journals (Sweden)

Colin C. Williams

2016-12-01

Full Text Available In recent years, participants in the informal economy have started to be viewed less as rational economic actors who engage in the informal economy when the pay-off is greater than the expected cost of being caught and punished, and more as social actors who engage when their tax morale (i.e., motivation to pay taxes is low. To evaluate this new social actor approach and the implications for tackling the informal economy, this paper reports evidence from 41,689 face-to-face interviews conducted across the European Union. Multilevel logistic regression analysis reveals a strong association between participation in the informal economy and the level of tax morale. Finding that higher tax morale (and thus lower participation in the informal economy is strongly correlated at the country-level with greater levels of state intervention and at the individual-level with characteristics such as gender, age, education and employment status, the outcome is to confirm a structuralist political economy explanation and refute the modernization and neo-liberal explanations and remedies, as well as to uncover the importance of some policy solutions not considered until now, including older citizens mentoring of younger people, and improving women’s participation in the labour force.

Nuclear proliferation: motivations, capabilities, and strategies for control

International Nuclear Information System (INIS)

Greenwood, T.; Feiveson, H.A.; Taylor, T.B.

1977-01-01

Two possible patterns of proliferation appear to involve the greatest risks for nuclear use or war. The first is proliferation to particular categories of states and the second dangerous possibility is proliferation at a rapid rate. But rapid proliferation could cause instabilities that might be too great for political systems and institutions to handle, making nuclear use of nuclear war more likely. Thus, any strategy for nonproliferation should especially attempt to prevent a rapid spread of nuclear weapons and to avert acquisition by states in the high-risk categories. Nuclear proliferation will also have important effects on world and regional stability for reasons not directly related to nuclear use. The mere possession of nuclear weapons by certain states could radically alter international perceptions and threaten global arrangements. The main concern in this discussion is to analyze the various incentives and disincentives--involving both security and political considerations--that will affect states' decisions about whether or not to acquire nuclear weapons. The discussion then turns to the means by which individual states and the international community can influence nuclear incentives and disincentives. The particularly important subject of the management of the international nuclear industry is addressed separately, followed by an analysis of nuclear acquisition, use, and threat by non-state entities. Finally, a general strategy for decreasing incentives and increasing disincentives is proposed and applied to four special categories of states

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.

An overview is given of the efforts to contain the nuclear weapons proliferation during half a century of man-controlled nuclear fission. An initial policy of denial did not work, a following period of cooperation needed a gradual strengthening of international assurances on the exclusively peaceful character of the flourishing use of nuclear techniques for power generation and of other applications. The focus of the nuclear weapon proliferation concern changed from the highly developed states to developing states. The Non-Proliferation Treaty laid the basis for a unique system of voluntarily accepted international inspections to verify the peaceful use of nuclear energy. The IAEA got the task to implement this 'Full Scope Safeguards' on all nuclear material and all nuclear activities in the non-nuclear weapon states. Thanks to the structure of the IAEA, in which both proponent and states with a critical attitude take part in the decision making process on the IAEA execution of its tasks, a balanced, and widely acceptable system emerged. International developments necessitated additional improvements of the non-proliferation system. The increase of strength of sub-national groups triggered international cooperation on physical protection, about a quarter of a century ago. More recently, it appeared that NPT states with assumed nuclear weapon ambitions operated in the margins between the interpretation of IAEA safeguards and the spirit and purpose of NPT. Improvements of the IAEA safeguards and a stronger cooperation between states, including the constraints which exporting states have imposed on nuclear supplies, strengthen the safeguards system.

Postdecisional counterfactual thinking by actors and readers.

Girotto, Vittorio; Ferrante, Donatella; Pighin, Stefania; Gonzalez, Michel

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.

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

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’.

Balancing influence between actors in healthcare decision making

Babad Yair M

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

Nuclear proliferation: linkages and solutions

Quester, G.H.

1979-01-01

Nuclear proliferation must be periodically re-examined as a moral as well as a practical foreign policy dilemma. The question is asked whether proliferation precludes a safe and peaceful world, or if a halt to proliferation is adequate without other arms control. The moral dilemma in foreign policy arises over the need to make practical choices which often serve one goal while sacrificing another. The ramifications of nuclear proliferation are examined and the conclusions reached that it is not an acceptable option. It is also decided that, because general disarmament steps will be more difficult to achieve, the world may have to accept a small number of nuclear arsenals as the price of state sovereignties. A high priority for making the effort to prevent proliferation is advised. 8 references

Cybersecurity threats to satellite communications: Towards a typology of state actor responses

Science.gov (United States)

Housen-Couriel, Deborah

2016-11-01

Cybersecurity threats to satellite communications are a relatively new phenomenon, yet have quickly come to the forefront of concern for the sustainability of satellite systems due to the vulnerabilities that such threats may exploit and negatively impact. These vulnerabilities are mission-critical: they include launch systems, communications, telemetry, tracking and command, and mission completion. They and other aspects of satellite communications depend heavily on secure and resilient cyber capabilities for all stages of the satellite's lifespan. Because of the inherently global nature of both satellite and cyberspace activities, these capabilities rely significantly on international cooperation for setting a baseline of agreed legal norms that protect satellites and satellite communications. This critical cooperation is relevant during all mission phases, from planning to final wrap-up. Under optimal circumstances, the norms and standards protecting satellites and satellite transmissions are developed and enforced by those nation-state actors that are committed to system operability and overall mission sustainability for those satellites launched under their aegis and responsibility. However, when breaches of international law do occur in the form of hostile cyber events that cause damage to satellite communications, a range of measures should be available to the victim state, provided by the appropriate legal regime or regimes. This article proposes that a comprehensive and integrative multi-stakeholder review be undertaken in the near future of the measures available under international law for responding to hostile acts directed at satellite systems and communications, in a manner that takes into account both existing regimes of international law reviewed herein, as well as considerations of cybersecurity. These measures will depend upon the characterization of hostile interference with satellite transmissions in accordance with a proposed typology of

Nuclear electric power and the proliferation of nuclear weapon states

International Nuclear Information System (INIS)

Walske, C.

1977-01-01

Control and elimination of the strategic nuclear weapons held by the nuclear weapon states remains the central problem in the arms control and disarmament field. Whether the proliferation of nations with nuclear weapons can be stopped is dubious. A sovereign nation will launch a nuclear weapons program if it has the motivation and resource. Motivation depends on military and political considerations. The necessary resources are economic and technological. Conditions in some sovereign states explain this issue. A survey of commercial nuclear power programs outside the USA lists 45 countries using or planning to use nuclear reactors for power generation. There are currently 112 reactors now operating outside the United States, 117 more under construction, 60 on order, and 180 planned. The U. S. as of December 1976 has 64 operating reactors, 72 under construction, 84 on order, and 8 planned. Nuclear trade and export policies are discussed. In this article, Mr. Walske says that American industry is convinced that the need for nuclear energy abroad is more urgent than in the United States; that in the long run, the breeder reactor must be developed to enable the supply of nuclear fuel to last for centuries; and that the experience of American industry abroad has convinced it that emphasis on restrictive, denial type policies will almost certainly fail--a collapse of what has been gained through the test ban treaty and the nonproliferation treaty

In summarizing the reasons for the fall of the Roman empire one has found about 210 significant ones. Without too much comparison the Roman empire and the EU natural gas market have similarities in connections between political authorities and the commercial actors in the European natural gas market. The area has consisted of several independent markets with different solutions that from 1988 has been tried integrated in an inner energy market. Several governmental and private actors have interest in this sector and both inhabitants and businesses are affected by alterations in a national natural gas market. This process is not yet finished. The thesis gives a broad description of the topic by including as many as possible of the EU member states. The topic is large and complex and the author has had to make a choice which parts to emphasize. There are chapters on the theoretical basis, the natural gas industry, what factors may explain the relationship between the political authorities and the commercial actors in the national natural gas market in each EU member and how does the EU Commission goals regarding free competition in the energy market affect the relationship between the political authorities and commercial actors in the national natural gas market

Understanding Health Information Seeking from an Actor-Centric Perspective

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.

Nuclear experts and nuclear weapons proliferation

International Nuclear Information System (INIS)

Mueller, H.

1979-01-01

In Germany the issue of nuclear weapons proliferation has attracted scant attention. Most potential nuclear weapon states are important trade partners of the FRG and, since further proliferation of nuclear weapons could worsen conflicts involving these, it should be in the FRG's interest to limit proliferation. The security of the FRG is also dependent on the common interest of the great powers to avoid nuclear war. The contradictory positions of Usa and the USSR on nuclear weapons policy regarding themselves and non-nuclear weapon states encourages less developed countries to see nuclear weaponry as useful. The NPT and IAEA safeguards have only limited inhibiting effect. The nuclear export policy of the FRG has been dominated by short term economic advantage, neglecting the negative long term effects of decreased political stability. The FRG should formulate a policy based on self-restraint, positive stimuli and extension of controls, using its economic strength to deter proliferation. (JIW)

Controlling nuclear proliferation

International Nuclear Information System (INIS)

Sweet, W.

Nuclear non-proliferation policy depends on the 1968 Non-Proliferation Treaty, in which countries promise not to acquire nuclear weapons in exchange for open access to peaceful nuclear technology, and a system of international safeguards that are imposed on exported nuclear equipment and facilities operated by parties to the treaty. Critics have feared all along that non-nuclear countries might circumvent or exploit the system to obtain nuclear weapons and that the Atoms for Peace plan would spread the very technology it sought to control. The nuclear weapons states would like everyone else to believe that atomic bombs are undesirable, but they continue to rely on the bombs for their own defense. Israel's raid on Iraq's nuclear reactor focused world attention on the proliferation problem and helped to broaden and sterengthen its prospects. It also highlighted the weakness that there are no effective sanctions against violators. Until the international community can ageee on enforcement measures powerful enough to prevent nuclear proliferation, individual countries may be tempted to follow Israel's example, 19 references

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.

Application of the actor model to large scale NDE data analysis

Coughlin, Chris

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.

ACToR Chemical Structure processing using Open Source ...

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. The Structure processing workflow integrates web services (PubChem and NIH NCI Cactus) to d

Emerging nuclear energy systems and nuclear weapon proliferation

Gsponer, A.; Sahin, S.; Jasani, B.

1983-01-01

Generally when considering problems of proliferation of nuclear weapons, discussions are focused on horizontal proliferation. However, the emerging nuclear energy systems currently have an impact mainly on vertical proliferation. The paper indicates that technologies connected with emerging nuclear energy systems, such as fusion reactors and accelerators, enhance the knowledge of thermonuclear weapon physics and will enable production of military useful nuclear materials (including some rare elements). At present such technologies are enhancing the arsenal of the nuclear weapon states. But one should not forget the future implications for horizontal proliferation of nuclear weapons as some of the techniques will in the near future be within the technological and economic capabilities of non-nuclear weapon states. Some of these systems are not under any international control. (orig.) [de

Lone Actor Terrorist Attack Planning and Preparation: A Data-Driven Analysis.

Science.gov (United States)

Schuurman, Bart; Bakker, Edwin; Gill, Paul; Bouhana, Noémie

2017-10-23

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.

Nuclear arbitration: Interpreting non-proliferation agreements

International Nuclear Information System (INIS)

Tzeng, Peter

2015-01-01

At the core of the nuclear non-proliferation regime lie international agreements. These agreements include, inter alia, the Nuclear Non-proliferation Treaty, nuclear co-operation agreements and nuclear export control agreements.1 States, however, do not always comply with their obligations under these agreements. In response, commentators have proposed various enforcement mechanisms to promote compliance. The inconvenient truth, however, is that states are generally unwilling to consent to enforcement mechanisms concerning issues as critical to national security as nuclear non-proliferation.3 This article suggests an alternative solution to the non-compliance problem: interpretation mechanisms. Although an interpretation mechanism does not have the teeth of an enforcement mechanism, it can induce compliance by providing an authoritative interpretation of a legal obligation. Interpretation mechanisms would help solve the non-compliance problem because, as this article shows, in many cases of alleged non-compliance with a non-proliferation agreement, the fundamental problem has been the lack of an authoritative interpretation of the agreement, not the lack of an enforcement mechanism. Specifically, this article proposes arbitration as the proper interpretation mechanism for non-proliferation agreements. It advocates the establishment of a 'Nuclear Arbitration Centre' as an independent branch of the International Atomic Energy Agency (IAEA), and recommends the gradual introduction of arbitration clauses into the texts of non-proliferation agreements. Section I begins with a discussion of international agreements in general and the importance of interpretation and enforcement mechanisms. Section II then discusses nuclear non-proliferation agreements and their lack of interpretation and enforcement mechanisms. Section III examines seven case studies of alleged non-compliance with non-proliferation agreements in order to show that the main problem in many cases

Canada's nuclear non-proliferation policy

International Nuclear Information System (INIS)

1982-05-01

Canada's non-proliferation safeguards policy has two objectives: 1) to promote a more effective and comprehensive international non-proliferation regime; and 2) to ensure that Canadian nuclear exports will not be used for any nuclear explosive purpose. By emphasizing the key role of the Non-Proliferation Treaty, promoting reliance upon and improvements in the IAEA safeguards system, treating nuclear weapon and non-weapon states alike, and working for new approaches covering reprocessing, Canada promotes attainment of the first objective. The second is served through the network of bilateral nuclear agreements that Canada has put into place with its partners. The Canadian objective in post-INFCE forums is to persuade the international community to devise a more effective and comprehensive non-proliferation regime into which Canada and other suppliers may subsume their national requirements

North-East Asia is distinguished by being potentially one of the world's most nuclearised regions. It includes two nuclear powers recognised by the Non-Proliferation Treaty (Russia and China), a proliferating state (North Korea) and three countries that could very quickly complete nuclear programmes (Japan, South Korea and Taiwan). Now that the question of nuclear proliferation has again surfaced on the international strategic scene, and that North Korea's test of October 2006 has introduced a new security paradigm into the region, how real is the risk of nuclear proliferation in North-East Asia?

Physical protection and its role in nuclear non-proliferation

International Nuclear Information System (INIS)

Nilsson, A.

1999-01-01

Non-proliferation of nuclear weapons has been one of the main concerns of the international community since the first nuclear weapons were developed. To prevent the proliferation of nuclear weapons has been on the agenda for individual States, groups of States and the international organizations. A number of treaties, conventions and agreements, the most important being the Non-Proliferation Treaty, have been negotiated to prevent the horizontal proliferation of nuclear weapons. States have concluded safeguards agreements with the IAEA to fulfill their obligations according to Article III.1 of the NPT. Other agreements relate to the prevention of vertical proliferation and also to the disarmament of nuclear weapons. It has also been recognized that sub-national, terrorist, or criminal activities may pose a proliferation risk. Illicit trafficking of nuclear material, particularly highly enriched uranium or plutonium, is a non-proliferation concern. States have recognized the need to prevent, as far as possible, the use of nuclear material in unlawful activities. The Convention of Physical Protection of Nuclear Materials, obligates the State Parties to protect nuclear material from theft during international transport, and to make unlawful possession, use, etc., of nuclear material a criminal offense, subject to punishment under national law. Although the physical protection convention recognizes the importance of the physical protection of nuclear material in domestic use, storage and transport, it does not obligate the State party to establish the necessary systems for this purpose. It is this limitation which led many States to believe that the international physical protection regime needs to be strengthened. Although not legally binding per se, the recommendations documented in INFCIRC/225/Rev. 4, The Physical Protection of Nuclear Material and Nuclear Facilities, has obtained wide recognition. There is recognition among States that protecting nuclear material

GAVE multi-actor process. A exemplified study with recommendations for a follow-up traject; GAVE multi-actor proces. Een voorbeeldstudie met aanbevelingen voor het vervolgtraject

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

Emotional labor actors: a latent profile analysis of emotional labor strategies.

Science.gov (United States)

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.

Full text: In my view, drastic nuclear disarmament by nuclear weapon States could be coupled with universal commitment to non-proliferation by non-nuclear weapon States by 1995 when the extension of the NPT Will be discussed. The incentives and disincentives for making and stockpiling nuclear weapons are first of all in the political and security fields, (Global and regional detente reduce the incentive, With the cold war gone, the US and Russia are now agreeing on far-reaching cuts in their nuclear arsenals and at some point the other declared nuclear weapon States Will follow.In the regional fields, we have seen how Argentina and Brazil are about to commit themselves to exclusively peaceful uses of the atom through the Latin American Tlatelolco Treaty. And we have seen how South Africa has joined the NPT. A new wave of States adhering to the NPT may be expected from countries in the former Soviet Union. Some have already come, others are on the way. Detente in the Middle East and on the Indian subcontinent would improve the outlook for non-proliferation in these areas. A second barrier to nuclear proliferation lies in export restrictions on sensitive nuclear material and equipment, Following the discoveries in Iraq, these restrictions are being strengthened in a large number of States. A third barrier to nuclear proliferation lies in the economic and political consequences that would follow for a State if IAEA safeguards inspection revealed activities aimed at the production of nuclear weapons. These must have a high degree of reliability. The case of Iraq showed that it was possible for a closed, highly militarized State to hide nuclear activities from the IAEA and the world We are now drawing the lessons from this case. It is not physically possible for inspectors to look into every building and basement in vast countries, They must have information about where to look, and the IAEA is significantly strengthening its information basis.

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.

Expression and contributions of the Kir2.1 inward-rectifier K+ channel to proliferation, migration and chemotaxis of microglia in unstimulated and anti-inflammatory states

Directory of Open Access Journals (Sweden)

Doris eLam

2015-05-01

Full Text Available When microglia respond to CNS damage, they can range from pro-inflammatory (classical, M1 to anti-inflammatory, alternative (M2 and acquired deactivation states. It is important to determine how microglial functions are affected by these activation states, and to identify molecules that regulate their behavior. Microglial proliferation and migration are crucial during development and following damage in the adult, and both functions are Ca2+-dependent. In many cell types, the membrane potential and driving force for Ca2+ influx are regulated by inward-rectifier K+ channels, including Kir2.1, which is prevalent in microglia. However, it is not known whether Kir2.1 expression and contributions are altered in anti-inflammatory states. We tested the hypothesis that Kir2.1 contributes to Ca2+ entry, proliferation and migration of rat microglia. Kir2.1 (KCNJ2 transcript expression, current amplitude, and proliferation were comparable in unstimulated microglia and following alternative activation (IL-4 stimulated and acquired deactivation (IL-10 stimulated. To examine functional roles of Kir2.1 in microglia, we first determined that ML133 was more effective than the commonly used blocker, Ba2+; i.e., ML133 was potent (IC50=3.5 M and voltage independent. Both blockers slightly increased proliferation in unstimulated or IL-4 (but not IL-10-stimulated microglia. Stimulation with IL-4 or IL-10 increased migration and ATP-induced chemotaxis, and blocking Kir2.1 greatly reduced both but ML133 was more effective. In all three activation states, blocking Kir2.1 with ML133 dramatically reduced Ca2+ influx through Ca2+-release-activated Ca2+ (CRAC channels. Thus, Kir2.1 channel activity is necessary for microglial Ca2+ signaling and migration under resting and anti-inflammatory states but the channel weakly inhibits proliferation.

The need of a multi-actor perspective to understand expectations from virtual presence: managing elderly homecare informatics.

2011-12-01

Different studies have analysed a wide range of use cases and scenarios for using IT-based services in homecare settings for elderly people. In most instances, the impact of such services has been studied using a one-dimensional approach, either focusing on the benefits for the patient or health service provider. The objective of this contribution is to explore a model for identifying and understanding outcomes of IT-based homecare services from a multi-actor perspective. In order to better understand the state of the art in homecare informatics, we conducted a literature review. We use experiences from previous research in the area of informatics to develop the proposed model. The proposed model consists of four core activities 'identify involved actors', 'understand consequences', 'clarify contingencies', 'take corrective actions', and one additional activity 'brainstorming IT use'. The primary goal of innovating organisations, processes and services in homecare informatics today, is to offer continued care, better decision support both to practitioners and patients, as well as effective distribution of resources. A multi-actor analysis perspective is needed to understand utility determination for the involved stakeholders.

Full Text Available The fall of the Ottoman Empire during World War One and theemergence of the modern state system in the Middle East have receivedsignificant attention in academic literature. However, the impacts thatthe proliferation of state borders in the 19th and 20th centuries havehad on political and economic integration within the Middle East isoften ignored. This study argues that between the mid-19th and mid-20th centuries the region underwent significant structural changes.Furthermore, these changes were driven by external intervention andinternal decline. A number of theoretical assumptions are positedconcerning the importance on integration and cooperation of thefollowing: the increase in borders and claims to sovereignty and theseparation of peoples/markets. The conclusions drawn are that thechange from a system characterised by large political actors andintegrated markets to one which is characterised by smaller states andseparated markets led to the disintegration of the region’s internalrelations.

Theoretical Approaches to Nuclear Proliferation

Directory of Open Access Journals (Sweden)

Konstantin S. Tarasov

2015-01-01

Full Text Available This article analyses discussions between representatives of three schools in the theory of international relations - realism, liberalism and constructivism - on the driving factors of nuclear proliferation. The paper examines major theoretical approaches, outlined in the studies of Russian and foreign scientists, to the causes of nuclear weapons development, while unveiling their advantages and limitations. Much of the article has been devoted to alternative approaches, particularly, the role of mathematical modeling in assessing proliferation risks. The analysis also reveals a variety of different approaches to nuclear weapons acquisition, as well as the absence of a comprehensive proliferation theory. Based on the research results the study uncovers major factors both favoring and impeding nuclear proliferation. The author shows that the lack of consensus between realists, liberals and constructivists on the nature of proliferation led a number of scientists to an attempt to explain nuclear rationale by drawing from the insights of more than one school in the theory of IR. Detailed study of the proliferation puzzle contributes to a greater understating of contemporary international realities, helps to identify mechanisms that are most likely to deter states from obtaining nuclear weapons and is of the outmost importance in predicting short- and long-term security environment. Furthermore, analysis of the existing scientific literature on nuclear proliferation helps to determine future research agenda of the subject at hand.

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.

The Impact of Drug Trafficking on Informal Security Actors in Kenya

Directory of Open Access Journals (Sweden)

Moritz Schuberth

2014-01-01

Full Text Available The Kenyan state is currently under pressure from two sides: First, numerous non-state armed groups have taken over the provision of security in areas where the state is practically absent. Second, drug-trafficking organizations are gaining ground as the country is increasingly being used as a major transit hub for narcotics. This article investigates the relationship between drug trafficking and informal security provision in Kenya and draws analogies from comparable experiences in Latin America and West Africa. Field research in Kenya has demonstrated that profit-oriented, informal security actors in Mombasa work for drug lords, while their counterparts in Nairobi are more likely to be hired by politicians. Moreover, faith-based vigilante groups in both cities appear to be less susceptible to external manipulation by drug traffickers. The article concludes by considering the potential consequences of an expansion of the drug trade in Kenya.

International Nuclear Information System (INIS)

Bouvier, G.

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)

Strengthening the nuclear non-proliferation regime

International Nuclear Information System (INIS)

Carlson, J.

2003-01-01

Although the nuclear non-proliferation regime has enjoyed considerable success, today the regime has never been under greater threat. Three states have challenged the objectives of the NPT, and there is a technology challenge - the spread of centrifuge enrichment technology and know-how. A major issue confronting the international community is, how to deal with a determined proliferator? Despite this gloomy scenario, however, the non-proliferation regime has considerable strengths - many of which can be developed further. The regime comprises complex interacting and mutually reinforcing elements. At its centre is the NPT - with IAEA safeguards as the Treaty's verification mechanism. Important complementary elements include: restraint in the supply and the acquisition of sensitive technologies; multilateral regimes such as the CTBT and proposed FMCT; various regional and bilateral regimes; the range of security and arms control arrangements outside the nuclear area (including other WMD regimes); and the development of proliferation-resistant technologies. Especially important are political incentives and sanctions in support of non-proliferation objectives. This paper outlines some of the key issues facing the non-proliferation regime

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.

Non-proliferation and disarmament

International Nuclear Information System (INIS)

Ritter von Wagner, A.

1993-01-01

In 1995 the Conference on the prolongation of the Non-Proliferation Treaty will take place. Will it be extended for a long term, indefinitely or only for a fixed period? The Federal Government of Germany advocates an unlimited extension of the Non-Proliferation Treaty. Others have different ideas alleging that the Treaty is imperfect and discriminating. It is a thorn in the side of many States, in particular of the Third World, which no longer want to put up with being treated as second-class states. One argument which is considered especially embarrassing by developing countries as a visible expression of such discrimination, are the nuclear tests which are still carried out by nuclear weapon states. Is the political situation still such that one needs those weapons? Strategists gradually find it difficult to argument; over and over again they claim that an abandonment of nuclear weapons would make the world unsafer. But development has gradually passed over them. Nevertheless, one finds it hard to throw overboard considerations which for years have determined one's thinking. (orig./HSCH) [de

The Influence of the Actor Network on the Innovative Process of Transgenic Soybean in Rio Grande Do Sul, Brazil

Doriana Daroit

2009-12-01

Full Text Available Rio Grande do Sul was the first Brazilian state to plant genetically modified soybean. The sowing occurred in 1998 with Roundup Ready soybean seeds from Monsanto smuggled from Argentina. The aim of this study is to investigate how this innovative process of planting transgenic soybean came about in Rio Grande do Sul based on the actor network involved in the period 1998 to 2003. Although the innovative process has been discussed in the literature on innovation management since the work of Schumpeter, there is still no clear understanding of the issues of interests and power that involve the innovative process. Given this, from within the literature we have sought a perspective that would understand the innovative process as being political. We adopted Actor Network Theory as a base for the discussion of the primary and secondary data obtained regarding the controversy surrounding transgenic soybean in RS. The results point to the existence of two translation chains that contribute towards the formation of actor networks.

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

Science.gov (United States)

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

2015-01-01

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

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.

The new US nuclear non-proliferation and export policy

International Nuclear Information System (INIS)

Welck, S. von.

1981-01-01

The future American nuclear non-proliferation and export policy will be determined chiefly by three elements: (1) Adherence to the former objective of nuclear non-proliferation. (2) A large and varied assortment of old and new tools for implementing this goal. (3) Much more differentiation in applying these tools in the light of the reliability, with respect to non-proliferation policy, of the respective partner. Consequently, it would make little sense for the new Administration to force upon allied industrialized countries, whose nuclear technologies are at the same level as that of the United States, restrictive rules on reprocessing and breeder technology. The new measures designed to curb proliferation are especially meant to destroy motivations that could cause states to own nuclear explosives. This also applies to the removal of economic motivations. (orig.) [de

Neuroimaging of the joint Simon effect with believed biological and non-biological co-actors.

Science.gov (United States)

Wen, Tanya; Hsieh, Shulan

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.

Are the rules for the right to self-defense outdated to address current conflicts like attacks from non-state actors and cyber-attacks?

Gonzalo J. Arias

2017-06-01

Full Text Available The latest US-led coalition’s attacks against ISIS in Syria raised the question whether states can use defensive force against non-state actors. Two critical incidents had previously triggered the discussion on the importance and consequences of cyber-attacks as a new form armed attacks. The first one occurred in Estonia in 2007, when the country experienced extensive computer hacking attacks that lasted several weeks. The second incident happened in 2008, during the Georgia–Russia conflict over South Ossetia, when Georgia experienced cyber-attacks similar to those suffered by Estonia in the previous year. Furthermore, on June 21, 2016, the central banks of Indonesia and South Korea were hit by cyber-attacks on their public websites since activist hacking group Anonymous pledged last month to target banks across the world. The previous incidents have created, once again, public questioning if the rules on the use of force and the right of self-defense established in the United Nations Charter are sufficient and efficient to address these new forms of attacks.

Pathways of undue influence in health policy-making: a main actor's perspective.

Hernández-Aguado, Ildefonso; Chilet-Rosell, Elisa

2018-02-01

It is crucial to know the extent to which influences lead to policy capture-by which the policy-making process is shifted away from the public interest towards narrow private interests. Using the case study of Spain, our aim was to identify interactions between public administration, civil society and private companies that could influence health policies. 54 semistructured interviews with key actors related to health policy. The interviews were used to gather information on main policy actors as well as on direct and subtle influences that could modify health policies. The analysis identified and described, from the interviewed persons' experiences, both the inappropriate influences exerted on the actors and those that they exerted. Inappropriate influences were identified at all levels of administration and policy. They included actions for personal benefits, pressure for blocking health policies and pressure from high levels of government in favour of private corporations. The private sector played a significant role in these strategies through bribery, personal gifts, revolving doors, negative campaigns and by blocking unfavourable political positions or determining the knowledge agenda. The interviewees reported subtle forms of influence (social events, offers of technical support, invitations, etc) that contributed to the intellectual and cultural capture of health officials. The health policy decision-making processes in Spain are subject to influences by stakeholders that determine a degree of policy capture, which is avoidable. The private sector uses different strategies, from subtle influences to outright corruption, taking advantage in many cases of flexible legislation. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

The Design of Migrant Integration Policies in Spain: Discourses and Social Actors

Directory of Open Access Journals (Sweden)

Belén Fernández Suárez

2017-03-01

Full Text Available Spain is one of the countries with the lowest social spending within the EU-15, and its welfare state has developed later and with less intensity. At the end of the 20th century, Spain became an immigration country, reaching 5.7 million immigrants in 2011. This article explores how the definition of migrant ‘integration’ is based more on a concept of universal rights and social cohesion by the main actors (political parties, trade unions, third sector organizations and immigrant associations than on a notion of a cultural type. We will also analyze how the influence of European policies and restrictive liberalism have led to the implementation of programmes which aim to make civic integration compulsory for the renewal of residence and work permits. The empirical evidence for this article stems from 60 qualitative interviews with social actors in migrant integration policies during 2010 and 2011. The impact of the economic crisis on the foreign population, especially regarding its position in the labor market, will also be considered, explaining the reduction of specific and general policies targeting the migrant population. This cut in social spending has involved a deinstitutionalization of this particular policy field.

A sleep state in Drosophila larvae required for neural stem cell proliferation

2018-01-01

Sleep during development is involved in refining brain circuitry, but a role for sleep in the earliest periods of nervous system elaboration, when neurons are first being born, has not been explored. Here we identify a sleep state in Drosophila larvae that coincides with a major wave of neurogenesis. Mechanisms controlling larval sleep are partially distinct from adult sleep: octopamine, the Drosophila analog of mammalian norepinephrine, is the major arousal neuromodulator in larvae, but dopamine is not required. Using real-time behavioral monitoring in a closed-loop sleep deprivation system, we find that sleep loss in larvae impairs cell division of neural progenitors. This work establishes a system uniquely suited for studying sleep during nascent periods, and demonstrates that sleep in early life regulates neural stem cell proliferation. PMID:29424688

The author states that there is no meaningful difference, from the point of view of proliferation between peaceful, civil, scientific application of nuclear fission, and the use of it in nuclear weapons. The proliferation of the nuclear technology for weapons appeared and appears to be closely connected with the spread of peaceful applications of nuclear technology. In connection with this, he discusses the Ultracentrifuge plant at Almelo (Netherlands) and the supply of nuclear technology by West-Germany especially to Brazil. Further the changed American policy and the possibility of an American/Russian deal to prevent the spread of the nuclear enrichment technology is discussed

'Two clicks and I'm in!' Patients as co-actors in managing health data through a personal health record infrastructure.

Zanutto, Alberto

2017-06-01

One of the most significant changes in the healthcare field in the past 10 years has been the large-scale digitalization of patients' healthcare data, and an increasing emphasis on the importance of patients' roles in cooperating with healthcare professionals through digital infrastructures. A project carried out in the North of Italy with the aim of creating a personal health record has been evaluated over the course of 5 years by means of mixed method fieldwork. Two years after the infrastructure was put into regular service, the way in which patients are represented in the system and patient practices have been studied using surveys and qualitative interviews. The data show that, first, patients have become co-actors in describing their clinical histories; second, that they have become co-actors in the diagnosis process; and finally, they have become co-actors in the management of time and space as regards their specific state of health.

Actor-specific contributions to the deforestation slowdown in the Brazilian Amazon.

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.

Characteristics of pornography film actors: self-report versus perceptions of college students.

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.

The Non-Proliferation Treaty seems to violate the fundamental principle of the quality of the states. However, if interpreted in the light of the latest developments of the international law, it is possible to justify the discriminations which it imposes on the non-nuclear states. A crucial point is the implementation of article VI by the nuclear states. If the latter procrastinate in nuclear disarmament the whole NPT-regime will collapse. (orig.) [de

The authors comment the content of the US Quadrennial Defence Review of 2006 (QDR 2006), and more particularly how this document addresses the struggle against proliferation. This struggle appears as a transverse issue within the main conventional pillars of the DoD's action (to defend homeland in depth, to prevent the acquisition and use of weapons of mass destruction by hostile actors, and to shape choices of countries at strategic crossroads). They recall that a previous release (QDR 2005) already set the principles and an age of maturity for the struggle against proliferation, and that an older release (QDR 2001) outlined the necessity for the USA to defend their homeland and allies against ballistic and cruise weapons (this meant the assignment of new means and weapons to conventional deterrence). Thus, the QDR 2006 defines means to be implemented and their operational structure, and therefore an almost definitive architecture for a new triad

Proliferation Persuasion. Coercive Bargaining with Nuclear Technology

Energy Technology Data Exchange (ETDEWEB)

Volpe, Tristan A. [George Washington Univ., Washington, DC (United States)

2015-08-31

Why do states wait for prolonged periods of time with the technical capacity to produce nuclear weapons? Only a handful of countries have ever acquired the sensitive nuclear fuel cycle technology needed to produce fissile material for nuclear weapons. Yet the enduring trend over the last five decades is for these states to delay or forgo exercising the nuclear weapons option provided by uranium enrichment or plutonium reprocessing capabilities. I show that states pause at this threshold stage because they use nuclear technology to bargain for concessions from both allies and adversaries. But when does nuclear latency offer bargaining benefits? My central argument is that challengers must surmount a dilemma to make coercive diplomacy work: the more they threaten to proliferate, the harder it becomes to reassure others that compliance will be rewarded with nuclear restraint. I identify a range of mechanisms able to solve this credibility problem, from arms control over breakout capacity to third party mediation and confidence building measures. Since each step towards the bomb raises the costs of implementing these policies, a state hits a sweet spot when it first acquires enrichment and/or reprocessing (ENR) technology. Subsequent increases in proliferation capability generate diminishing returns at the bargaining table for two reasons: the state must go to greater lengths to make a credible nonproliferation promise, and nuclear programs exhibit considerable path dependency as they mature over time. Contrary to the conventional wisdom about power in world politics, less nuclear latency thereby yields more coercive threat advantages. I marshal new primary source evidence from archives and interviews to identify episodes in the historical record when states made clear decisions to use ENR technology as a bargaining chip, and employ this theory of proliferation persuasion to explain how Japan, North Korea, and Iran succeeded and failed to barter concessions from the

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

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

Díaz-Castro, Lina; Arredondo, Armando; Pelcastre-Villafuerte, Blanca Estela; Hufty, Marc

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.

Proliferation resistance assessment of pyro processing

Energy Technology Data Exchange (ETDEWEB)

Kwon, E. H.; Ko, W. I.; Kim, H. D. [KAERI, Daejeon (Korea, Republic of)

2012-10-15

In 2002, world experts gathered and defined the term proliferation resistance as 'the characteristic of a nuclear energy system that impedes the diversion or undeclared production of nuclear material, or misuse of technology, by State in order to acquire nuclear weapons or other nuclear explosive devices.' The same report also defines the following terms: Intrinsic barriers (technical features) of proliferation resistance are features that result from the technical design of nuclear energy systems, including those that facilitate the implementation of extrinsic measures. Extrinsic barriers (institutional measures) of proliferation resistance are features that result from the decisions and undertakings of states related to nuclear energy system. Intrinsic barriers are further divided into material barriers.the 'intrinsic, or inherent, qualities of materials that reduce the inherent desirability or attractiveness of the material as an explosive' and technical barriers. The 'intrinsic technical lements of the fuel cycle, its facilities, processes, and equipment that serve to make it difficult to gain access to materials and/or to use or misuse facilities to obtain weapons usable materials.' Material barriers include isotopic, chemical, radiological, mass and bulk, and detectability, whereas technical barriers include facility unattractiveness, accessibility, available fissile mass, detectability of and time required for diversion, and skills, expertise, and knowledge. Assessing the proliferation resistance of pyro processing is meaningful only when compared with other processes. This paper attempts to discuss the features of pyro processing by comparing it with direct disposal and aqueous separation processes from a proliferation resistance viewpoint.

Prevention of nuclear weapon proliferation in South Asia is considered a a difficult challenge. The paper discusses the difficulties met in implementing the nuclear non-proliferation policy due to numerous disputes concerning China, North and South Korea, India and Pakistan, and the countries of former Soviet Union. Matters preventing proliferation are mentioned as well as obstacles to non-proliferation proposing that decisions whether voluntary or, eventually, compulsory would have to be consistently enforced by the Security Council, if states are to rely upon those methods for their security

Weapons of mass destruction (WMD) are a serious international concern and have been at least for nearly a century. After World War I, the Geneva Protocol of 1925 prohibited the use of chemical and biological warfare. The advent of nuclear weapons, with their extraordinary destructive capacity, made the proliferation of WMD an even greater concern after the Second World War. Moreover, during the post-Cold War period the dangers of proliferation of WMD have increased due to regional tensions, the dissolution of the Soviet Union (and resulting looser controls over weapons scientists and dangerous materials), and the ready availability of sensitive technologies. More than ten States have active WMD-related programmes, and probably about ten more have capabilities to start them. At the same time, non-State actors (transnational organized criminal communities and international terrorist networks) today are seen as playing an increasingly active role in unauthorized access to and proliferation of sensitive materials, technologies, and weapons. After 9/11, the risk of such actors using WMD components as a tool for blackmailing governments has become a real scenario, still with low probability but with highly significant - and disastrous consequences. The international community has responded to problems and challenges in two major ways. The first has been the elaboration of multilateral international treaty regimes intended to prevent the proliferation of WMD. These include the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), the Chemical Weapons Convention (CWC), and the Biological and Toxin Weapons Convention (BWC). The second approach has been the formation of non-treaty arrangements, generally known as 'suppliers' clubs', aimed at preventing the proliferation of technologies and equipment that could be used by a 'proliferant' State or non-State actor to develop WMD and/or delivery systems (e.g., ballistic or cruise missiles) associated with such weapons.

Competing actors in the climate change arena in Mexico: A network analysis.

Ortega Díaz, Araceli; Gutiérrez, Erika Casamadrid

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.

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.

Tosaki, Hirofumi

2005-01-01

Combating nuclear proliferation has been one of the top priorities for the international community in the post post-Cold War era, and the United States has been taking initiative for tackling the problems. The current Bush administration has placed value high on the effective and concrete actions - including the use of military forces - for such efforts. It is imperative that such actions should be taken in resolving the nuclear proliferation. However, the United States has been criticized that it has disregarded the existing nuclear non-proliferation regime, and that its non-proliferation policy has given negative implications to the regime. Combating nuclear proliferation should be pursued in balanced approach with legitimacy, in consideration of the discriminately nature of the regime as well as of its three pillars - nuclear non-proliferation, nuclear disarmament and peaceful use of nuclear energy.

2017-12-01

Full Text Available Public-Private Partnerships (PPPs have emerged along with the growing role of corporations in global development. One of the largest forms of PPP today is the UN Global Compact. The UN Global Compact involves of companies, NGOs, IGOs and state governments. All of them are trying to realize globalization with a more humanist face with attention to the protection of human rights, environment, labor standards and anti-corruption. Engaging private actors in global governance, The UN Global Compact raises many issues such as power, authority, and legitimacy. The effort to tackle it all is to increase PPP accountability. This research seeks to describe what efforts can be made to enhance private accountability within the international regime. The research undertaken is a descriptive study, focuses on public-private partnerships in the UN Global Compact regime. The study found that there were two attempts that could be done. First, by involving the stakeholders in the development of procedures, mechanisms, reporting and monitoring associated with trying to improve the company’s reputation. Second, by looking at corporate relations as agent and UN Global Compact as principal in principal-agent relation in the international regime.

Inflamed areas are characterized by infiltration of immune cells, local hypoxia and alterations of cellular redox states. We investigated the impact of hypoxia on survival, proliferation, cytokine secretion, intracellular energy and redox state of human CD4(+) T cells. We found that pathophysiological hypoxia (<2% O2 ) significantly decreased CD4(+) T-cell survival after mitogenic stimulation. This effect was not due to an increased caspase-3/7-mediated apoptosis or adenosine-5'-triphosphate (ATP) consumption/depletion. However, the ability of stimulated T cells to proliferate was reduced under hypoxic conditions, despite increased expression of CD25. Pathophysiological hypoxia was also found to modify intracellular ROS (iROS) levels in stimulated T cells over time as compared with levels found in normoxia. Physiological hypoxia (5% O2 ) did not decrease CD4(+) T-cell survival and proliferation or modify iROS levels as compared with normoxia. We conclude that pathophysiological hypoxia affects T-cell proliferation and viability via disturbed IL-2R signalling downstream of STAT5a phosphorylation, but not as a result of impaired cellular energy homeostasis. We suggest iROS links early events in T-cell stimulation to the inhibition of the lymphoproliferative response under pathophysiological hypoxic conditions. The level of iROS may therefore act as a mediator of immune functions leading to down-regulation of long-term T-cell activity in inflamed tissues. © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

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

Science.gov (United States)

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.

Brain-Machine Interface control of a robot arm using actor-critic rainforcement learning.

2012-01-01

Here we demonstrate how a marmoset monkey can use a reinforcement learning (RL) Brain-Machine Interface (BMI) to effectively control the movements of a robot arm for a reaching task. In this work, an actor-critic RL algorithm used neural ensemble activity in the monkey's motor cortext to control the robot movements during a two-target decision task. This novel approach to decoding offers unique advantages for BMI control applications. Compared to supervised learning decoding methods, the actor-critic RL algorithm does not require an explicit set of training data to create a static control model, but rather it incrementally adapts the model parameters according to its current performance, in this case requiring only a very basic feedback signal. We show how this algorithm achieved high performance when mapping the monkey's neural states (94%) to robot actions, and only needed to experience a few trials before obtaining accurate real-time control of the robot arm. Since RL methods responsively adapt and adjust their parameters, they can provide a method to create BMIs that are robust against perturbations caused by changes in either the neural input space or the output actions they generate under different task requirements or goals.

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

Science.gov (United States)

Lejars, Caroline; Daoudi, Ali; Amichi, Hichem

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.

Comparative analysis of proliferation resistance assessment methodologies

Comparative analysis of the methodologies was performed based on the discussions in the international workshop on 'Assessment Methodology of Proliferation Resistance for Future Nuclear Energy Systems' held in Tokyo, on March 2005. Through the workshop and succeeding considerations, it is clarified that the proliferation resistance assessment methodologies are affected by the broader nuclear options being pursued and also by the political situations of the state. Even the definition of proliferation resistance, despite the commonality of fundamental issues, derives from perceived threat and implementation circumstances inherent to the larger programs. Deep recognitions of the 'difference' among communities would help us to make further essential and progressed discussion with harmonization. (author)

African Initiated Churches’ potential as development actors

Philipp Öhlmann

2016-11-01

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.

A Study on the Improvement of the INPRO Proliferation Resistance Assessment Methodology

International Nuclear Information System (INIS)

Ko, Won Il; Chang, Hong Lae

2010-07-01

Within the International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO), a methodology for evaluating proliferation resistance (INPRO PR methodology) has been developed. However, User Requirement (UR) 4 regarding multiplicity and robustness of barriers against proliferation ('innovative nuclear energy systems should incorporate multiple proliferation resistance features and measures') remains to be developed. Because the development of a methodology for evaluating User Requirement 4 requires an acquisition/diversion pathway analysis, a systematic approach was developed for the identification and analysis of pathways for the acquisition of weapons-useable nuclear material. This approach was applied to the DUPIC fuel cycle which identified several proliferation target materials and plausible acquisition/diversion pathways. Based on these results, proliferation strategies that a proliferant State could adopt for undeclared removal of nuclear material from the DUPIC fuel cycle have been developed based on the objectives of the proliferation of the State, the quality and quantity of the target material, the time required to acquire the material for the proliferation, and the technical and financial capabilities of the potential proliferant State. The diversion pathway for fresh DUPIC fuel was analyzed using the INPRO User Requirements 1, 2 and 3, and based on these results an assessment procedure and metrics for evaluating the multiplicity and robustness of proliferation barriers has been developed. In conclusion, the multiplicity and robustness of proliferation barriers is not a function of the number of barriers, or of their individual characteristics but is an integrated function of the whole. The robustness of proliferation barriers is measured by determining whether the safeguards goals can be met. The harmonization of INPRO PR methodology with the GIF PR and PP methodology was also considered. It was suggested that, as also confirmed by IAEA

Nestel, Debra; Muir, Elizabeth; Plant, Marilyn; Kidd, Jane; Thurlow, Sue

2002-09-01

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.

The non-proliferation policies of the 1970s were based largely on the misconception that the main danger lay in the possible misuse of civil nuclear-power plants for the production of weapon materials. In consequence their aim, whether by means of denial or control, was to ensure that such misuse was made more difficult in all countries with nuclear-power industries. Less attention was paid to the potential for misuse of the nuclear-research plants in the handful of countries outside the non-proliferation system. The resulting difficulties placed in the way of countries developing their nuclear-power industries damaged relations between the supplier and the consumer states, and discredited any new efforts aimed at strengthening the non-proliferation system. By contrast, the 1980s began, first in INFCE and then in the Committee on Assurances of Supply, with a concerted attempt to re-establish a dialogue based on a relationship of trust between the supplier and the customer states. But a restored consensus will not, on its own, deal with the problem of those states that are outside the non-proliferation system and that have the capability to produce nuclear weapons. The outcome of the work of the Committee on Assurances of Supply may help to attract some of those states into the system, but more needs to be done either by adapting the NPT, making adherence to it appear more attractive, or by devising some alternative code of behaviour for states not party to the Treaty and by seeking to remove the political obstacles that lie in the way of at least some of the potential weapon states adhering to the Treaty

SRC: marker or actor in prostate cancer aggressiveness.

A key question for urologic practitioners is whether an apparently organ-confined prostate cancer (PCa) is actually aggressive or not. The dilemma is to specifically identify among all prostate tumors the very aggressive high-grade cancers that will become life-threatening by developing extra-prostatic invasion and metastatic potential and the indolent cancers that will never modify a patient's life expectancy. A choice must be made between several therapeutic options to achieve the optimal personalized management of the disease that causes as little harm as possible to patients. Reliable clinical, biological, or pathological markers that would enable distinctions to be made between aggressive and indolent PCas in routine practice at the time of initial diagnosis are still lacking. The molecular mechanisms that explain why a PCa is aggressive or not are also poorly understood. Among the potential markers and/or actors in PCa aggressiveness, Src and other members of the Src kinase family, are valuable candidates. Activation of Src-dependent intracellular pathways is frequently observed in PCa. Indeed, Src is at the cross-roads of several pathways [including androgen receptor (AR), TGFbeta, Bcl-2, Akt/PTEN or MAPK, and ERK …], and is now known to influence some of the cellular and tissular events that accompany tumor progression: cell proliferation, cell motility, invasion, epithelial-to-mesenchymal transition, resistance to apoptosis, angiogenesis, neuroendocrine differentiation, and metastatic spread. Recent work even suggests that Src could also play a part in PCa initiation in coordination with the AR. The aim of this review is to gather data that explore the links between the Src kinase family and PCa progression and aggressiveness.

Worst-case Throughput Analysis for Parametric Rate and Parametric Actor Execution Time Scenario-Aware Dataflow Graphs

Directory of Open Access Journals (Sweden)

Mladen Skelin

2014-03-01

Full Text Available Scenario-aware dataflow (SADF is a prominent tool for modeling and analysis of dynamic embedded dataflow applications. In SADF the application is represented as a finite collection of synchronous dataflow (SDF graphs, each of which represents one possible application behaviour or scenario. A finite state machine (FSM specifies the possible orders of scenario occurrences. The SADF model renders the tightest possible performance guarantees, but is limited by its finiteness. This means that from a practical point of view, it can only handle dynamic dataflow applications that are characterized by a reasonably sized set of possible behaviours or scenarios. In this paper we remove this limitation for a class of SADF graphs by means of SADF model parametrization in terms of graph port rates and actor execution times. First, we formally define the semantics of the model relevant for throughput analysis based on (max,+ linear system theory and (max,+ automata. Second, by generalizing some of the existing results, we give the algorithms for worst-case throughput analysis of parametric rate and parametric actor execution time acyclic SADF graphs with a fully connected, possibly infinite state transition system. Third, we demonstrate our approach on a few realistic applications from digital signal processing (DSP domain mapped onto an embedded multi-processor architecture.

Neuromuscular control of the point to point and oscillatory movements of a sagittal arm with the actor-critic reinforcement learning method.

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.

Proliferation and Nonproliferation in the Early Twenty-First Century. The Permanent Five Hold the Key to Success

International Nuclear Information System (INIS)

Santoro, David

2012-01-01

It is a truth universally acknowledged that nuclear proliferation constitutes a threat to international peace and security. However little known its causes may be, this truth is so well fixed in international public consciousness that it is considered an utmost requirement to address the problem expeditiously. Is the international community indeed properly geared to respond quickly, strongly, and unanimously to proliferation? If so, how? Writing for Foreign Affairs in 1961, the late Fred Ikle asked, 'After Detection-What?'He expressed concerns that the international community focused too exclusively on how to detect violations to arms control agreements. He explained that determining the consequences of violations after detection was also essential and described 'a program to deter evasion', but remained pessimistic about its prospects for success. Four decades later, in a 2001 article for the Nonproliferation Review, Brad Roberts assessed how the problem had changed. He showed that many policy tools had been developed, but that they did not guarantee success. Anticipating many of the debates of the 2000's, he reflected on the dilemma of resorting to multilateral action (sanctioned by the UN Security Council) or US unilateral action, and concluded that there was a crisis of confidence about the nonproliferation regime and the role of the major powers. Over ten years have passed since Roberts's review article. It is now a good time to stand back and take stock of how the problem has evolved. To this end, this paper begins with an assessment of the nonproliferation landscape between 2001 and 2011 by looking at the changes that affected the proliferation problem itself, the tools to address that problem, and the actors involved in the process to solve it. Although progress was made to better tackle it, the paper suggests that pessimism is in order today. On that basis, it moves on to explore what the 'winning agenda' might be, what it entails, and what the prospects

Does interdependence alleviate proliferation risks in Asia?

International Nuclear Information System (INIS)

Yoshida, Osamu

1997-01-01

As the extension Conference of the Non-Proliferation Treaty ended with its unlimited extension without any modification of the treaty obligation of the nuclear-weapon states to nuclear disarmament, the prospect of the regime to incorporate those suspected nuclear powers in Asia, namely India, Pakistan and Israel, has become dark. In this paper the problem of proliferation risk centred in India is analysed. It is well known that India was the first to criticize the Non-Proliferation Treaty regime as highly discriminating between the five nuclear haves and the rest. As was always the case, India's point is logically persuasive and consistent. However, it is also true that the logical or legal point of view does not always solve the problem. Therefore, we look at the regional and international political constellation in which any assertion has to be constructed. At present there is very little possibility that this region will become nuclear-free. This is because the horizontal proliferation, that has seemingly taken place here, is the result of a 'nuclear chain reaction', starting with a minor nuclear-weapon state, China. However, the economic upsurge in the region now throws the nuclear chain-reactions into the background. It has come to a standstill and the future of nuclear proliferation here will have to be decided by global nuclear disarmament, as there is no motivation on the side of the two Asian giants to agree on the reduction in their nuclear arsenals, though under American pressure, another suspected nuclear power, Pakistan, may have to give up its nuclear development plan

Andre, P.; Delisle, C.E.; Reveret, J.-P.

2003-01-01

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

Sweden and the making of nuclear non-proliferation: from indecision to assertiveness

Dassen, L. van

1998-03-01

Swedish research on nuclear weapons started at a modest scale in 1945 but was soon expanded. By the early 1950s the research programme started to face some of the problems that were going to accompany it for the rest of its life: different priorities and cost-estimates were made by the sectors that wanted to develop nuclear energy and those working on the bomb. Moreover, an introduction of nuclear weapons would lead to a major redistribution of resources to the disadvantage of the navy and army. The public and political debates intensified during the 1950s and culminated in 1960. At first, pro-nuclear voices had been strongest but were soon challenged by interest groups, unions and peace movements. 1960, a committee within the government had established a compromise: Nuclear weapons research for production of weapons would be terminated, while research on the consequences of nuclear weapons would continue. It was a cosmetic decision that could cover for a continued research on weapons design. Nevertheless, there are some general qualities from the debates that indicate why the outcome was that Sweden signed the NPT in 1968. First, the number of interested persons, groups movements and party politicians engaged in the issue increased every time the issue came up. Secondly, the segments of society that supported the nuclear option remained roughly the same. No strong movements rallied to the defence of this position. On the other hand, the anti-nuclear wing received more and more followers. Third, there was a marked tendency by virtually all actors (except the military) to include every sign of progress in international disarmament and non-proliferation efforts as arguments against Swedish proliferation. Since 1968, the non-proliferation choice has ben manifested through Sweden''s adherence to the NPT and this has been accompanied by a strong commitment to other non-proliferation initiatives

Cities concentrate populations, consumptions, levers of actions, and are places of various experiments for energy transition. This book aims at giving an overview of possible scenarios of development of renewable energies in urban context. It is based on interviews of actors of the energy, building and urban planning sectors by researchers in town planning, management, technology, political and economic sciences. The authors examine what would occur if large companies would manage entire quarters, if local authorities would supervise production and supply, if the State would take control of all fields of action again, or if consumer cooperatives would exchange energy and pool productions. In its different chapters, the book presents four scenarios of energy coordination in urban context by 2040, discuss energy transition in urban spaces, discuss the perspectives of evolution towards more autonomous cities and quarters from an energetic point of view, and discuss business models and urban energetic innovations

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

Science.gov (United States)

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.

New market actors: economic social movements and politicized consumers

Directory of Open Access Journals (Sweden)

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.

Heath Sector Network Governance and State-building in South Kivu, Democratic Republic of Congo.

Longstanding patterns of interaction exist between state and non-state actors seeking to improve public health in Democratic Republic of Congo (DRC). DRC is a weak state, and, in many cases, private actors have stepped in to fill the void created by the lack of state health care provision. However, the role of these interactions in creating a governance network in the health sector has been underexplored. Using data from 18 months of qualitative field research, this study aimed to explore governance networks in DRC's health sector, examining how multiple stakeholders work to manage the health system and how the resulting governance network has been relevant for the state-building process. The findings demonstrate that the health sector in South Kivu is emerging as an arena of networked governance based on active partnerships between state institutions and non-state actors. Interactions between state and non-state actors account for the persistence of the health sector in a setting characterized by state weakness. However, networked governance does not function optimally, because, although non-state interventions fill the void where the state falls short, the DRC state has faced the challenge of interacting with partners with fragmented and horizontally competing agendas. Although weak, the shadow of state authority is present in the arena of stakeholders' interactions, as the state plays a determining role by providing a regulatory framework. Overall, the findings show that the interactive engagement of non-state actors contributes to improving institutional capacity through these actors' engagement with state institutions for health system management and institutional development. However, although networked health sector governance does contribute to state capacity, it is difficult to assess the real influence of these interactions on the state-building process in a context of critical fragility, where coordination and alignment have been problematic. © The

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

International aspects of non-proliferation policy

International Nuclear Information System (INIS)

Aucoin, P.A.

1978-01-01

There are currently two areas on the national scene and one on the international scene that require immediate attention. The first is relief under contracts for enrichment services, an area in which the US can still demonstrate its desire to become a stable and continuous source of supply. The second national area is the Nuclear Non-Proliferation Act of 1977. The United States must proceed very cautiously, however, for if discretion and very careful judgment are not used, the Act will immediately be branded as a blatant effort on the part of the US to control the energy options of other sovereign states. The international area is that of the International Nuclear Fuel Cycle Evaluation program. This medium exists for wise and deliberate growth of a commercial nuclear power program which can serve the global community. The next three years probably allow one remaining chance for successful containment of weapons proliferation. If we do not recognize the rights of every sovereign state to voluntarily participate and agree, we, as members of the global community, will have failed

Exports and experts:proliferation risks from the new Commonwealth

International Nuclear Information System (INIS)

Potter, W.C.

1992-01-01

Ironically, given the Cold War history and Western stereotypes about Soviet misbehavior, the long-standing experience of US-Soviet cooperation on nonproliferation may have made US policy-makers less attentive to, and less concerned about, signs of change in Soviet nuclear export policy. The breakup of the Soviet Union and the nuclear inheritance of its successor states belatedly focused Western attention on the proliferation risks posed by the disintegration of central authority. Most concern to date, however, has continued to emphasize the problems of nuclear command and control. But the nonproliferation threats associated with the unregulated export of sensitive nuclear material, technology, and equipment may be equally great, and present problems that are already real. At the same time, the new nation-building process in the Soviet successor states presents opportunities for expanding the NPT and international safeguards, containing the nuclear brain drain, promoting the cleanup of hazardous nuclear waste, enhancing international capabilities for monitoring proliferation, and building new communities of nonproliferation specialists. A rare occasion now exists for Western policy-makers to have a direct impact on the long-term nuclear export and non-proliferation behavior of the successor states to the Soviet Union. The speed and seriousness with which the West undertakes this task will largely determine how much ground, if any, will be lost from its decades-long effort to stop the proliferation of nuclear weapons

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.

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.

Comparisons of Multilevel Modeling and Structural Equation Modeling Approaches to Actor-Partner Interdependence Model.

Science.gov (United States)

Hong, Sehee; Kim, Soyoung

2018-01-01

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.

The Rights of Private Economic Actors Under the World Trade Organization Agreements in Indonesia

Intan Soeparna

2012-09-01

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.

Non-proliferation

Deiseroth, D.; Gustafsson, S.

1993-01-01

The issue of Nuclear Non Proliferation has been moved to a leading place on the contemporary international security agenda. What about the situation of nuclear weapons and nuclear technology in Russia, Kazakhstan, Ukraine and Belorussia? Why did the IAEA-inspectors totally failed to discover any sign of Iraq's clandestine nuclear-weapon programme before the Gulf War? Do the NATO and their nuclear power states violate Art. VI of the Non-Proliferation-Treaty (NPT), because they are - despite the end of the cold war - not willing to renounce of the ''option of the first use of nuclear weapons''? Does the NPT establish a form of nuclear apartheid? What will be the situation if the NPT-Extension-Conference in 1995 will be unable to obtain a majority of the parties for any one extension proposal? Do we need a new international nuclear control agency with severe powers, a sort of nuclear Interpol? The Colloquium ''Saving NPT and abolishing Nuclear Weapons'', held in Stockholm in September 1992, organized by the Swedish and the German Sections of IALANA, tried to analyse some of the raised issues.

The international nuclear non-proliferation system: Challenges and choices

International Nuclear Information System (INIS)

Simpson, J.; McGrew, A.G.

1984-01-01

When a topic has been under discussion for almost 40 years there is a danger that the literature will become excessively esoteric and that, as Philip Grummett suggests, '...a new scholasticism will arise' (p.79). Originating in a November l982 seminar co-sponsored by the British International Studies Association and the Foreign and Commonwealth Office, this volume is a refreshing, well conceived, and well written antidote to that trend. It is also well timed for the 1985 NPT Review Conference. The eight chapters of the volume are divided into three sections. Following an introduction by Anthony McGrew that touches on all the major themes of the volume, the first section deals with the existing non-proliferation system. In three chapters the historical, institutional and policy-making elements of the present system are outlined. There is a vignette on the Nuclear Suppliers Group in Wilmshurst's chapter one (pp. 28-33). Fischer's informative chapter on the IAEA is followed by Gummett's examination of policy options, including, for example, the linking of conventional weapons transfer to non-proliferation policies. The second section, also of three chapters, examines current issues: the state of the international nuclear industry, and the non-proliferation policies of the United States and Britain. Walker's chapter focuses chiefly on change in the industry-from monopoly to pluralism in suppliers, the effect of the economic recession, and the combined effect of these two factors on international politics. Devine's American non-proliferation chapter is a statement of the State Department view, whilst Keohane's chapter on Britain attempts to put the Trident procurement into a proliferation context. The British chapter is present because of ethnocentric considerations

The Non-Proliferation Treaty: Fifteen years after entry into force

International Nuclear Information System (INIS)

1985-01-01

The need to halt a wider spread of nuclear weapons grew out of the realization that the increase in the number of countries possessing such weapons would increase the threat to world security. As the Treaty on the Non-Proliferation of Nuclear Weapons clearly states in its preamble, the proliferation of nuclear weapons would seriously enhance the danger of nuclear war. The Treaty - also known as the non-proliferation Treaty - was concluded in 1968, at a time when there were already five nuclear-weapon Powers: the United States, the Soviet Union, the United Kingdom, France and China. This fact sheet is intended to provide background material on the Treaty, including the events that led to its conclusion, an overview of its provisions and the developments at the two previously held Review Conferences

Position paper on nuclear proliferation issues preventing nuclear proliferation. A duty for the nuclear community

Goldschmidt, Pierre; Bonin, Bernard [ENS High Scientific Council, Brussels (Belgium)

2010-06-15

The production of electricity from nuclear power plants is widely seen today as having an increasing role to play in meeting global energy requirements in a sustainable manner. Conscious of the inherently sensitive nature of nuclear technology and materials the ENS-HSC (European Nuclear Society - High Scientific Council) is well aware that a severe safety, security, environmental or proliferation mishap stemming from nuclear energy anywhere in the world would undermine the potential for nuclear energy to contribute to the global energy supply and the minimization of harmful carbon emissions. While the safety of nuclear power plants has continuously improved over the last three decades, the same degree of success cannot be claimed when it comes to the achievements of the international community in stemming the risk of nuclear weapons proliferation. This unfortunate situation is due to both technical and political reasons. The European nuclear industry is committed to the exclusively peaceful use of nuclear energy and to export nuclear facilities and related materials, equipment and technology solely in accordance with relevant national export laws and regulations, Nuclear Suppliers Group guidelines and pertinent United Nations Security Council Resolutions. The ENS-HSC considers that, as a manifestation of their strong commitment to nonproliferation, it is important for the nuclear industry to pay special attention to and promote proliferation-resistant designs and to take IAEA safeguards requirements into account at the design stage. Preventing nuclear proliferation is primarily the responsibility of states but, as major stakeholders, the nuclear industry and scientific community should actively support nuclear disarmament as foreseen in the Non-Proliferation Treaty and measures necessary to strengthen the non-proliferation regime, particularly the international control of the flux of nuclear material and technology.

An Introduction to The Interdisciplinary Concept of Risk-Informed Proliferation Resistance

International Nuclear Information System (INIS)

Gouveia, Fernando

2010-01-01

The nonproliferation community is rich in diverse attempts aimed at predicting and preventing attempts at nuclear proliferation. Such efforts, however, are rarely incorporated into a holistic approach well-suited to solving both existing and emerging proliferation dilemmas. This division is particularly apparent with respect to the partition that separates the socio-political and technical approaches to solving such problems, approaches which are very often developed and utilized in isolation. Complicating matters further, are the diverse positions taken by various entities as they relate to the secure implementation of nuclear energy world-wide. Such positions range from the obdurate belief in the supposed inherent proliferation resistance of traditional spent fuel, to those regarding all nuclear energy systems as inherently proliferation prone, given their core reliance on the sensitive technologies of enrichment and reprocessing. Accordingly, moderates have argued for a risk-informed approach to combat nuclear proliferation, combining institutional factors, such as IAEA safeguards, with innovative reactor and fuel designs to bring about an acceptable notion of proliferation resistance. To this end, methodologies have been developed, which seek to assess and score attained proliferation resistance. Most notably, these include, the Proliferation Resistance and Physical Protection (PR and PP) methodology prepared by the GEN-IV International Forum and the IAEA's International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO). Such approaches have greatly advanced the concept of proliferation resistance; however, they remain limited by their exclusive concentration on the technological determinants of proliferation and non-consideration of other, equally important, socio-political determinants. This limitation is significant as numerous incidents have illustrated the ability of atypical states to find alternate paths to proliferation, for example

Non-proliferation and safeguards in South Africa

Broodryk, Alta

2001-01-01

South Africa occupies a unique position in the history of the Non-Proliferation Treaty in being the only country with a nuclear weapons capability that was voluntary terminated before acceding to the Treaty. The first nuclear device built was completed in December 1982, five more devices followed at an orderly pace of less than one per year and on 26 February 1990 cabinet officially implemented the termination of its nuclear deterrent capability. The events that flowed from the termination was that South Africa: Acceded to the Non-Proliferation Treaty (10 July 1991); Signed Comprehensive Safeguards Agreement, INFCIRC/394, (16 September 1991); Submitted its initial inventory of nuclear material (30 September 1991); and Received first verification team from the Agency (November 1991). South Africa, being dedicated to the prevention of the proliferation of Nuclear Weapons became a party to various non-proliferation treaties, regimes and groups. The National Non- Proliferation Policy, as published in a Cabinet memorandum, also clearly states this commitment. To comply with the requirements of the Treaty and Agreement the following two acts were published: The Nuclear Energy Act; The Non-Proliferation of Weapons of Mass Destruction Act. The Minister of Minerals and Energy is the State Authority for the implementation of the Safeguards Agreement in South Africa, however, the Minister delegated this Authority to NECSA's Safeguards Division. To implement the requirements of the various acts, control regimes and treaties a State System for Accounting and Control of Nuclear Material, based on the ISO 9001:2000 standard, was designed. This standard focuses on customer satisfaction, continuous improvement, the demonstration of commitment and the prevention of non-conformity. To comply with the requirements of the standard the following procedures were established and maintained: A Quality Manual; Customer focus; Control of documents; Control of quality records; Internal Audits

Actor modelling and its contribution to the development of integrative strategies for management of pharmaceuticals in drinking water.

Science.gov (United States)

Titz, Alexandra; Döll, Petra

2009-02-01

Widespread presence of human pharmaceuticals in water resources across the globe is documented. While some, but certainly not enough, research on the occurrence, fate and effect of pharmaceuticals in water resources has been carried out, a holistic risk management strategy is missing. The transdisciplinary research project "start" aimed to develop an integrative strategy by the participation of experts representing key actors in the problem field "pharmaceuticals in drinking water". In this paper, we describe a novel modelling method, actor modelling with the semi-quantitative software DANA (Dynamic Actor Network Analysis), and its application in support of identifying an integrative risk management strategy. Based on the individual perceptions of different actors, the approach allows the identification of optimal strategies. Actors' perceptions were elicited by participatory model building and interviews, and were then modelled in perception graphs. Actor modelling indicated that an integrative strategy that targets environmentally-responsible prescription, therapy, and disposal of pharmaceuticals on one hand, and the development of environmentally-friendly pharmaceuticals on the other hand, will likely be most effective for reducing the occurrence of pharmaceuticals in drinking water (at least in Germany where the study was performed). However, unlike most other actors, the pharmaceutical industry itself does not perceive that the production of environmentally-friendly pharmaceuticals is an action that helps to achieve its goals, but contends that continued development of highly active pharmaceutical ingredients will help to reduce the occurrence of pharmaceuticals in the water cycle. Investment in advanced waste or drinking water treatment is opposed by both the wastewater treatment company and the drinking water supplier, and is not mentioned as appropriate by the other actors. According to our experience, actor modelling is a useful method to suggest effective

El actor aglutinante: Nacionalismo y sociedad civil en Quebec.

Full Text Available This article aims to reconstruct the history of civil society in Quebec (Canada to relate it with nationalism, the rise of the welfare state, trade unions, Catholic Church and civil society, the dynamic forces of society. Through in-depth interviews with key leaders, exploration of institutional archives and specific literature, we work with a particular case that, when compared to Catalonia, will allow us to evaluate the importance of civil society within nationalism. This actor is not usually considered as the central subject of researches and rarely token into account, unlike political parties, their leaders or intellectuals. Currently, in a context of crisis of the state and political parties, it has begun to be considered that civil society can be a key factor for its ability to produce alliances between sectors, build hegemony and dialogue directly with the population. The study is divided into four parts: 1 the development of the theoretical framework along with the construction of the object of study and the hypotheses; 2 an analysis about the importance of the involvement of civil society in the construction of the nationalist movement in Quebec; 3 a comparison with the Catalan case; and, 4 finally some conclusions.

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.

Putting Gino's lesson to work: Actor-network theory, enacted humanity, and rehabilitation.

Science.gov (United States)

Abrams, Thomas; Gibson, Barbara E

2016-02-01

This article argues that rehabilitation enacts a particular understanding of "the human" throughout therapeutic assessment and treatment. Following Michel Callon and Vololona Rabeharisoa's "Gino's Lesson on Humanity," we suggest that this is not simply a top-down process, but is cultivated in the application and response to biomedical frameworks of human ability, competence, and responsibility. The emergence of the human is at once a materially contingent, moral, and interpersonal process. We begin the article by outlining the basics of the actor-network theory that underpins "Gino's Lesson on Humanity." Next, we elucidate its central thesis regarding how disabled personhood emerges through actor-network interactions. Section "Learning Gino's lesson" draws on two autobiographical examples, examining the emergence of humanity through rehabilitation, particularly assessment measures and the responses to them. We conclude by thinking about how rehabilitation and actor-network theory might take this lesson on humanity seriously. © The Author(s) 2016.

Bridging centrality: A new indicator to measure the positioning of actors in R&D networks

Energy Technology Data Exchange (ETDEWEB)

Scherngell, T.; Wanzenboeck, I.; Berge, L.

2016-07-01

In the recent past, we can observe growing interest in the STI community in the notion of positioning indicators, shifting emphasis to actors in the innovation process and their R&D inter-linkages with other actors. In relation to this, we suggest a new approach for assessing the positioning of actors relying on the notion of bridging centrality (BC). Based on the concept of bridging paths, i.e. a set of two links connecting three actors across three different aggregate nodes (e.g. organisations, regions or countries), we argue that triangulation in networks is a key issue for knowledge recombinations and the extension of an actor's knowledge base. As bridges are most often not empirically observable at the individual level of research teams, we propose an approximated BC measure that provides a flexible framework for dealing with the aggregation problem in positioning actors. Hereby, BC is viewed as a function of an aggregate node's (i) participation intensity in the network, (ii) its openness to other nodes (i.e. the relative outward orientation of network links), and iii) the diversification of links to other nodes. In doing so, we provide an integrative perspective that enables us to achieve a better understanding of the positioning of certain actors in R&D networks. An illustrative example on the co-patent network of European regions demonstrates the performance and usefulness of our BC measure for networks constructed at the aggregated level, i.e. regions in our example. A region's outward orientation and the diversification of its network links moderates the influence of regional scale on network centrality. This is a major strength of the measure, and it paves the way for future studies to examine the role of certain aggregate node's, and, by this, contributes to the debate on positioning indicators in the STI context.

Getting acquainted: Actor and partner effects of attachment and temperament on young children's peer behavior.

McElwain, Nancy L; Holland, Ashley S; Engle, Jennifer M; Ogolsky, Brian G

2014-06-01

Guided by a dyadic view of children's peer behavior, this study assessed actor and partner effects of attachment security and temperament on young children's behavior with an unfamiliar peer. At 33 months of age, child-mother attachment security was assessed via a modified Strange Situation procedure, and parents reported on child temperament (anger proneness and social fearfulness). At 39 months, same-sex children (N = 114, 58 girls) were randomly paired, and child dyads were observed during 3 laboratory visits occurring over 1 month. Actor-partner interdependence models, tested via multilevel modeling, revealed that actor security, partner anger proneness, and acquaintanceship (e.g., initial vs. later visits) combined to predict child behavior. Actor security predicted more responsiveness to the new peer partner at the initial visit, regardless of partner anger proneness. Actor security continued to predict responsiveness at the 2nd and 3rd visits when partner anger was low, but these associations were nonsignificant when partner anger was high. Actor security also predicted a less controlling assertiveness style at the initial visit when partner anger proneness was high, yet this association was nonsignificant by the final visit. The findings shed light on the dynamic nature of young children's peer behavior and indicate that attachment security is related to behavior in expected ways during initial interactions with a new peer, but may change as children become acquainted.

Nuclear proliferation: Some context and consequences

International Nuclear Information System (INIS)

Ford, C. A.

2007-01-01

The article addressed the importance of nonproliferation and supporting and reinforcing nonproliferation commitments. The most important benefit of the NPT has been in its contribution to the security of individual states party, as well as to regional and international security, through the obligations which help to prevent any further proliferation of nuclear weapons. The NPT therefore powerfully augments the national security of every state party, and not merely just the NPT nuclear weapons states. Indeed, it is the countries of the developing world, as well as many other non-nuclear weapon states, that could suffer the most in security terms if a non-nuclear weapons state in the developing world suddenly acquired T he Bomb a nd became emboldened to engage in threats and adventurism against its neighbors. The nonproliferation regime hinges upon the steps that all countries take on their own and with like-minded allies to further nonproliferation goals - and whether the international community can successfully shape the calculations of present-day and future would-be proliferation in useful ways. The nonproliferation regime, therefore, includes not just the NPT and other legally-binding obligations but complex dynamics of persuasion and deterrence that employ many different tools. The NPT helps establish the core nonproliferation obligations toward which many of the tools in the international community's tool kit are directed.

Local regulation of haemopoietic stem cell proliferation in mice following irradiation

Ali, A.M.; Riches, A.C.; Wright, E.G.

1989-01-01

Changes in the kinetic state of pluripotent haemopoietic spleen colony forming cells (CFU-S) and of the CFU-S proliferation stimulator have been studied following whole-body X-irradiation. Rapid recruitment of CFU-S into cell cycle by 30 min after irradiation was observed following low doses (0.5 Gy) but a delay of 6 h occurred after higher doses (1.5 and 4.5 Gy). These changes in proliferative state correlated with the presence of the CFU-S proliferation stimulator. CFU-S irradiated in vitro in bone marrow plugs were also recruited into cycle illustrating directly the local nature of the feedback mechanism. CFU-S removed from 1.5 Gy irradiated recipients at a time when they were not in cycle were not responsive to the CFU-S proliferation stimulator. The CFU-S proliferation stimulator was produced by Ia positive cells in the irradiated bone marrow. The regulation changes occurring shortly after irradiation cannot simply be controlled by the size of the CFU-S compartment. (author)

Humanoids Learning to Walk: A Natural CPG-Actor-Critic Architecture.

Science.gov (United States)

Li, Cai; Lowe, Robert; Ziemke, Tom

2013-01-01

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.

on the results, these tools must use consistent semantics for the model. Yet, a monolithic semantic model is just as complex as the entity it describes. 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 layers are also planned to underpin...... independent specialized verification tools. 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....

Chinas carbon-intensity target: climate actors and policy developments

Energy Technology Data Exchange (ETDEWEB)

Stensdal, Iselin

2012-11-01

China has become the largest GHG emitting country, and announced in 2009 its first policy objective measured in carbon emissions. The carbon-intensity target is to reduce the carbon intensity by 40-45 % by 2020 compared to 200 levels. Since then there has been further policy developments in order to attain the reduction carbon intensity and steer China towards a low-carbon development. The 12th 5-year plan (2011-2015) is strong on incentives for reducing China's carbon intensity such as energy conservation measures and the establishment of new market-based mechanisms. While the central government forms the policies, the implementation is dependent on a range of actors. In addition to the climate change bureaucracy, the positive forces and actors on GHG mitigation is presented. All in all, there are promising developments in China for the years to come.(auth)

Nuclear power and nuclear weapons proliferation

International Nuclear Information System (INIS)

Anon.

1978-01-01

An appropriate non-proliferation treaty should not discriminate among the non-weapon states, but should seek a cooperative approach with all countries seeking nuclear power and willing to accept international safeguards. Near-term proliferation problems, represented by nations already on the threshold of weapon capability, should not be confused with the long-term problem of world-wide nuclear development. The first can be handled with incentives and disincentives imposed on specific countries, while the latter involves the distribution of plutonium on the basis of alternative fuel cycles. To retain world leadership, U.S. efforts along these lines should be to encourage a dialogue between suppliers and recipients and to coordinate the economic and security issues of its own non-proliferation and foreign policies. One option is a U.S. commitment to a multinational fuel storage and reprocessing facility. Technical evaluation and demonstration of alternative fuel cycles to reach an international consensus would be a parallel activity

The international nuclear non-proliferation system: Challenges and choices

Energy Technology Data Exchange (ETDEWEB)

Simpson, J.; McGrew, A.G.

1984-01-01

When a topic has been under discussion for almost 40 years there is a danger that the literature will become excessively esoteric and that, as Philip Grummett suggests, '...a new scholasticism will arise' (p.79). Originating in a November l982 seminar co-sponsored by the British International Studies Association and the Foreign and Commonwealth Office, this volume is a refreshing, well conceived, and well written antidote to that trend. It is also well timed for the 1985 NPT Review Conference. The eight chapters of the volume are divided into three sections. Following an introduction by Anthony McGrew that touches on all the major themes of the volume, the first section deals with the existing non-proliferation system. In three chapters the historical, institutional and policy-making elements of the present system are outlined. There is a vignette on the Nuclear Suppliers Group in Wilmshurst's chapter one (pp. 28-33). Fischer's informative chapter on the IAEA is followed by Gummett's examination of policy options, including, for example, the linking of conventional weapons transfer to non-proliferation policies. The second section, also of three chapters, examines current issues: the state of the international nuclear industry, and the non-proliferation policies of the United States and Britain. Walker's chapter focuses chiefly on change in the industry-from monopoly to pluralism in suppliers, the effect of the economic recession, and the combined effect of these two factors on international politics. Devine's American non-proliferation chapter is a statement of the State Department view, whilst Keohane's chapter on Britain attempts to put the Trident procurement into a proliferation context. The British chapter is present because of ethnocentric considerations.

State and multilateralism, a theoretical approach. Transformations in a globalized international society

Full Text Available The State, classical international actor, has had to readaption to the new dynamics in the International Society and has given prominence to other actors. In this logic, it´s relevant to analyze the role in the international system after the Cold War to evaluare whether it is still an actor capable of responding to the functional needs of the society. For this, reaffirms its commitment to multilateralism as a response to the main issue on the international agenda. Namely, is reactivated as an ideal tool to manage structural changes, despite the different interpretations of United States, the European Union or the BRICS. The object of this analysis contribute to the academic debate and focuses on studying the transformations of the State in the globalized international society where multilateralism has become a concept discussed and a common practice in the international discourse, despite its complexity and the different visions and interpretations by different actors. Multilateralism granted the State a path of cooperation and understanding as a guiding principle and foreign policy legitimizing discourse.

Laser enrichment: a new path to proliferation

International Nuclear Information System (INIS)

Casper, B.M.

1977-01-01

The use of lasers to obtain enriched uranium is an easier and cheaper method than methods currently in use. The immediate concern is that it could promote easy access to nuclear weapons by countries that do not presently have them. Mr. Casper feels that the U.S. government is working against itself; while the State Department is seeking to block one path to proliferation, ERDA laboratories are developing new technology that could open another. The proliferation implications have not been factored in a serious way into the decisions to proceed with this research. It is also clear that the United States does not now have a comprehensive policy that deals with all potentially important paths to proliferation, including laser enrichment. Mr. Casper states that there is still time to stop and consider whether laser enrichment should be developed, in light of its broader consequences. But this will not happen if the decisions are left exclusively in the hands of those promoting the technology, the author says. It is just this sort of situation that prompted the creation of several government institutions to provide independent assessments of new technologies. The Office of Technology Assessment, the Nuclear Regulatory Commission, and the Arms Control and Disarmament Agency all have the authority to intervene. Laser enrichment provides a good test of these institutions and of the viability of the concept of technology assessment. The status, benefits and risks, and the policy needed on laser research are discussed

Positive steps toward non-proliferation

Greenhalgh, G.

1979-08-30

Russel W. Fox and Mason Willrich in their paper, International Custody of Plutonium Stocks: A First Step Toward an International Regime for Sensitive Nuclear Energy Activities, advocate placing excess plutonium in an international custodial facility; critical criteria governing releases are outlined so that, on one hand the owners can have high confidence that their plutonium will be returned promptly, under appropriate circumstances, and on the other hand, all the other participating and concerned countries can have confidence in the assurance that plutonium will be released only for immediate use in a defined and approved civil purpose. The Stockholm International Peace Research Institute in the 1978 issue of its Year Book, recognizes a move towards a more positive approach to the problem of nuclear proliferation. It is noted that the non-proliferation strategies of the main supply countries have largely concentrated on a two-pronged approach of technology denials with tightening of safeguards. But already, enrichment, reprocessing, and breeder reactor programs extend far beyond the five nuclear weapon states. History testifies to the limitations of a policy of technical denials. SIPRI recognizes that another way to dissuade non-nuclear weapon states from creating their own enrichment or reprocessing plants would be to establish an open market for these services, a market characterized by diversity and competition. So far, there has been no case where a country has developed nuclear explosives by diverting material from a civil power station. Development of nuclear weapons by various countries is briefly noted and areas where strengthening of the Non-Proliferation Treaty is needed are noted. (MCW)

International humanitarian actors and governments in areas of conflict: challenges, obligations, and opportunities.

Science.gov (United States)

Harvey, Paul

2013-10-01

For too long international humanitarian aid has neglected the primary responsibility of the state to assist and protect its citizens in times of disaster. A focus on the role of the state in contexts where governments are active parties to a conflict and are failing to live up to these responsibilities is difficult and underpins many of the recurring dilemmas of humanitarian action. The fundamental principles of humanitarian action should offer a framework for principled engagement with governments in situations of conflict but too often they are still interpreted as shorthand for ignoring governments. Using principles to inform engagement with both states and other international actors engaged in crises could provide a way forward. However, this would need to be a humanitarian agenda that engages with developing country governments, with non-OECD (Organisation for Economic Co-operation and Development) donors, and with the stabilisation and security agendas of Western governments, and not one that attempts to ring-fence an ever-shrinking isolationist humanitarian space. © 2013 The Author(s).

In the USSR Nuclear Society in 1991 the special working group on the problems of nuclear weapons non-proliferation and nuclear materials control, uniting the experts of different types (nuclear physicists, lawyers, teachers), was created. This group became the mechanism of the practical Nuclear Society activity realization in this sphere. Three milestones of the innovative activity can be specified. First Milestone. In January 1992 the Central Nuclear Society Board (of the International Public Nuclear Society Association) published a special appeal to the First Leaders of all countries - former USSR republics. This address paid a special attention to the unity of the USSR power-industrial complex, and numerous problems arisen while separating this complex, including nuclear weapons non-proliferation problems, were indicated as well. Second Milestone. In 1992 and 1993 the Nuclear Society experts issued two selection 'Nuclear Non-proliferation and Control Problems' including reviewing basic papers. In addition, materials on non-proliferation and control are published regularly in the organs. Third Milestone.In 1993 - 1997 some special scientific and technical events (conferences, workshops, meetings) allowing to analyze the joint international projects and contracts outcomes, and establish new contacts between the specialists of NIS, Baltic states and others, have been hold

The Social Construction of Transgenic Corn: Relevant Social Actors in Chihuahua

Marco Antonio Fernández Nava

2016-01-01

Full Text Available According to the socio-technical perspective, the meaning of a technological artefact does not lie within the artefact itself. Analyzing transgenic corn from a socio-technical perspective means taking one’s research beyond the artefact itself. To do this, it is necessary to overcome and avoid determinist positions, be they social or technological. This work takes as it point of departure the Social Construction of Technology Focus (SCOT. In this sense, transgenic corn is an unfinished object that is affected by an onslaught of struggles, opinions, agreements, disagreements, designs and redefinitions of the relevant social actors. These groups, the Democratic Campesino Front, El Barzón, National Agro-dynamic and Regional Agricultural Union of Yellow Corn Producers (UNIPRO, demonstrate how technological development is a social process. The deconstruction of transgenic corn according to the perspectives of these different social actors is key to the process of constructivist analysis: to take the artefacts just as each social actor views them. The objective of this study then is to describe how the different social groups, through their actions, construct and deconstruct the meaning of transgenic corn in Chihuahua, Mexico.

Dynamics of proliferating powers. For a new interdisciplinary approach

2002-01-01

The authors highlight that conventional approaches to the proliferation of arms of massive destruction are not sufficient to provide a generic evaluation grid whereas such a grid is clearly needed. In a first part, they discuss the contribution of various theories of proliferation of arms of massive destruction which generally address this phenomenon through three main points of view: legal and political means of struggle against proliferation, analysis of technical capacities, and motivations of proliferating States. The authors indicate and briefly present the various associated models. Then, they develop the basis of an analytical method aimed at a better understanding of the 'proliferating power', and at using various approaches, and notably that related to leader's psychology. They comment the content of studies already published on these issues, more precisely address the psycho-sociological dimension, outline the interest of diplomacy in this psychological approach, evoke the different typologies of personality, and propose elements of a new matrix of analysis of the proliferation phenomenon which takes national resources, history and strategic context, type of political regime, history and personality typology of the leader, and international dependencies, alliances, elites and mediators of the inner power, and public opinions into account

Foxon, Timothy J.; Pearson, Peter J.G.; Arapostathis, Stathis; Carlsson-Hyslop, Anna; Thornton, Judith

2013-01-01

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.

Counterterrorism in the Russian Arctic: legal framework and central actors

Directory of Open Access Journals (Sweden)

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.

Weber, M.; Hasselmann, K.

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

Male and Female Social Actor Representation in Four Corners 4: A Critical Discourse Perspective

Directory of Open Access Journals (Sweden)

Ali Roohani

2014-12-01

Full Text Available This study aims at investigating the linguistic representation of male and female social actors in the Four Corners 4 textbook, drawing on CDA. More specifically, van Leeuwen’s (1996 framework, which highlights the connection of linguistic and social practices, is used as the analytical framework to examine gendered social actors in this English language teaching (ELT textbook. To this end, content analysis was done to explore the frequency and proportion of each social actor. Quantitative and qualitative data analysis showed that there were some differences, though not statistically significant, between males and females regarding substitution, individualization, and activation. Males, in contrast with females, were included more as active and famous actors in social circumstances and they were more individualized. In addition, they were more activated through circumstantialization and participation. On the other hand, the case of formalization was mostly observed for males. Moreover, males and females were distributed equally in the textbook in terms of classification, genericization, and collectivization. The results reveal that the gender bias still exists, though to a small degree, in this ELT textbook, which is taught as a substitution for the previous ELT textbooks in many language schools in Iran.

The actor set-up of TV advertising. A new process for hybrid formats

2008-01-01

The paper introduces a basic description of the advertising process in TV advertising and discusses how this process might be altered when 30 second spots are replaced by hybrid advertising formats such as sponsoring and placements. For each actor in the process the potential benefit of hybrid advertising is identified and the respective interest in changing the process is deduced. A qualitative interview study with representatives from each actor in the process is used to illustrate that con...

The Latino population in the United States is quickly growing, and its unintended pregnancy rate is increasing. To decrease unintended pregnancies, couples must mutually agree on family planning. Communication between partners is one key factor identified in successful family planning for couples. Therefore, the purpose of this study was to examine sexual communication and its associations with sexual relationship power, general communication, and views on family planning. The Actor-Partner Interdependence Model was used to analyze dyadic influences of the chosen variables. Forty immigrant Latino couples were recruited from prenatal care clinics. The study results were grouped according to the three types of power structures: exhibition of men's traditional machismo values, exhibition of women's increased power in their relationships, and exhibition of men's and women's own empowerment with sexual communication. There was a negative association between men's views on family planning and women's sexual communication (exhibition of machismo values); a negative association between women's sexual relationship power and their partners' sexual communication (exhibition of women's increased power); and positive associations between men's and women's general communication and sexual communication (exhibition of men's and women's own empowerment). Dyadic influences of sexual communication and associated variables need to be incorporated into interventions to facilitate family planning for couples.

Widening the scope? How intermediary actors can shape energy consumption

DEFF Research Database (Denmark)

Maneschi, Davide

2013-01-01

This paper deals with energy consumption in the residential sector and with the implementation of measures to reduce it. While most research dealing with energy consumption has targeted factors and drivers at the individual user level, more recent works have highlighted collective aspects...... of (energy) consumption, both to explain the resilience of consumption patterns and to identify leverage points for the reduction of energy use. One understudied aspect of this discussion is the way “intermediary” actors – those actors who are neither policy makers, nor users, nor energy providers...... – influence energy consumption. This paper presents a review of the literature on intermediaries, providing an overview of their roles and contextualizing their functions in energy efficiency improvements. The review shows how the concept of intermediaries has been used in research dealing with innovation...

INCREASED PROLIFERATION RESISTANCE FOR 21ST CENTURY NUCLEAR POWER

International Nuclear Information System (INIS)

Demuth, Scott F.; Thomas, Ken E.; Wallace, Richard K.

2007-01-01

World energy demand and greenhouse gases are expected to significantly increase in the near future. Key developing countries have identified nuclear power as a major contributor to their future energy sources. Consequently, the US and others are currently exploring the concept of a Global Nuclear Energy Partnership (GNEP) to address the concerns of nuclear proliferation. This effort is also being encouraged by the International Atomic Energy Agency (IAEA). While the IAEA currently provides the framework for monitoring of state sponsored nuclear proliferation by way of international treaties, a complimentary action is to promote more proliferation resistant fuel cycles and advanced safeguards technology. As such, it is the responsibility of current technology owners to increase their nuclear fuel cycle proliferation resistance. For those countries that have an active and well-developed fuel cycle, it will require future enhancements. For those countries with extensive nuclear energy experience, yet less active programs, it requires re-engagement for technology development and deployment. The following paper discusses potential fuel cycle and technology changes that affect proliferation resistance; and consequently, may form the basis of future technology development efforts.

Defining and Theorizing Terrorism: A Global Actor-Centered Approach

Directory of Open Access Journals (Sweden)

Omar Lizardo

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.

[Who is against prevention? A map of policy actors favoring smoking in Spain].

Science.gov (United States)

Granero, Lluís; Villalbí, Joan Ramón; Gallego, Raquel

2004-01-01

For a comprehensive approach to policies on smoking, the map of actors related to tobacco and their political ties needs to be identified. The present article constitutes the first attempt at this task in Spain. Analysis of the press, industry publications, and interviews with key people. Active actors favoring smoking in Spain were identified and classified according to their characteristics, the sphere in which they act, and their preferred territorial arena. We identified tobacco companies (Altadis and Philip Morris dominate the market), tobacco trade organizations (tobacconists), front-line organizations created by the tobacco industry (The Smokers for Tolerance Club), organizations of tobacco growers, and processing companies. Distribution to retailers is dominated by Logista, owned by Altadis. Other sectors to take into account are vending companies and those manufacturing related products (cigarette paper, matches or lighters). The contacts of these actors with the public administration are reviewed, notable among which are the role of the Commissioner for the Tobacco Market, the Ministry of Agriculture, the Ministry of Finance and the Ministry of the Economy. Ties were also found with employers' organizations, some political parties, and unions, as well as with other sectors with social influence such as the media and advertising sectors. The map of actors favoring smoking in Spain is complex and goes beyond the confines of the tobacco industry. Understanding this web is crucial to promoting comprehensive prevention policies.

Full Text Available This article offers an approach to the interactions between State and social actors, based on the analysis of three cases in which opportunistic or violent actors were associated with policies to promote growing of palm oil in Colombia. We move away from other approaches which describe these interactions as cooptation and suggest they can be better understood as processes associated with the exercise of indirect domination by the State. To this end, we present an overall framework of analysis, review relevant policies, offer a description of the cases, and propose three mechanisms of indirect state domination: privateers, friends and Gullivers.

The Non-Proliferation Treaty increases security

International Nuclear Information System (INIS)

Kahiluoto, K.

1995-01-01

Extension of the Nuclear Non-Proliferation Treaty indefinitely was a historic decision. The Treaty is the most extensive international agreement on security policy to date; now its obligations have become a permanent part of international justice. Moreover, the NPT represents a political and moral obligation. Through the NPT, the international community has made a permanent commitment to restrict the proliferation of nuclear weapons. Increasing pressures will be applied to the few countries still outside the NPT, making it more likely that these countries will eventually change their views. The likelihood of regional bans on nuclear weapons in the Middle East and in Asia, too, will increase. The Treaty promotes the establishment of new nuclear-free zones. The nuclear-free zone in Latin America - the countries covered by the Tlatelolco Treaty - is already very close to its full implementation. Finland is firmly committed to the obligations of the Non-Proliferation Treaty. The NPT Conference of 1995 was among the first international meetings in which Finland participated, and took an active role, as a Member State of the European Union. (orig.)

User requirements and criteria for proliferation resistance in INPRO

2004-01-01

In designing future nuclear energy systems, it is important to consider the potential that such systems could be misused for the purpose of producing nuclear weapons. INPRO set out to provide guidance on incorporating proliferation resistance into innovative nuclear energy systems (INS). Generally two types of proliferation resistance measures are distinguished: intrinsic and extrinsic. Intrinsic features consist of technical design features that reduce the attractiveness of nuclear material for nuclear weapon program, or prevent the diversion of nuclear material or production of undeclared nuclear material for nuclear weapons. Extrinsic measures include commitments, obligations and policies of states such as the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) and IAEA safeguards agreements. INPRO has produced five basic principles and five user requirements for INS. It emphasizes that INS must continue to be an unattractive means to acquire fissile material for a nuclear weapon program. It also addresses as user requirements: 1) a balanced and optimised combination of intrinsic features and extrinsic measures, 2) the development and implementation of intrinsic features, 3) an early consideration of proliferation resistance in the development of INS and 4) the utilization of intrinsic features to increase the efficiency of extrinsic measures. INPRO has also developed criteria, consisting of indicators and acceptance limits, which would be used by a state to assess how an INS satisfies those user requirements. For the first user requirement, the most important but complex one, INPRO provides a 3-layer hierarchy of indicators to assess how unattractive a specific INS would be as part of a nuclear weapon program. Attributes of nuclear material and facilities are used as indicators to assess intrinsic features. Extrinsic measures imposed on the system are also assessed. Indicators to assess defence in depth for proliferation resistance include the number and

The first nuclear weapon was detonated in August 1945 over Japan to end World War II. During the past six decades, the majority of the world's countries have abstained from acquiring nuclear weapons. However, a number of countries have explored the nuclear weapons option, 23 in all. Among them, 14 countries have dropped their interest in nuclear weapons after initiating some efforts. And nine of them today possess nuclear weapons. These countries include the five nuclear weapons states - U.S., Russia, U.K., France, and China - and the four non- NPT member states - Israel, India, Pakistan, and North Korea. Many of these countries initially used civilian nuclear power technology development as a basis or cover for their military program. Recent proliferation incidents in Iraq, Iran, and North Korea brought the world together to pay much attention to nuclear nonproliferation. With the expected surge in the use of nuclear energy for power generation by developing countries, the world's nuclear nonproliferation regime needs to be better prepared for potential future challenges. For the world's nuclear nonproliferation regime to effectively cope with any future proliferation attempts, early detection of potentially proliferation-related activities is highly desirable. Early detection allows the international community to respond and take necessary actions - ideally using political and diplomatic influences without resorting to harsh measures such as sanctions or military actions. In this regard, a capability to quantitatively predict the chance of a country's nuclear proliferation intent or activities is of significant interest. There have been various efforts in the research community to understand the determinants of nuclear proliferation and develop quantitative tools to predict nuclear proliferation events. These efforts have shown that information about the political issues surrounding a country's security along with economic development data can be useful to

Nuclear Fuel Leasing, Recycling and proliferation: Modeling a Global View

International Nuclear Information System (INIS)

Crozat, M P; Choi, J; Reis, V H; Hill, R

2004-01-01

On February 11, 2004, U.S. President George W. Bush, in a speech to the National Defense University stated: ''The world must create a safe, orderly system to field civilian nuclear plants without adding to the danger of weapons proliferation. The world's leading nuclear exporters should ensure that states have reliable access at reasonable cost to fuel for civilian reactors, so long as those states renounce enrichment and reprocessing. Enrichment and reprocessing are not necessary for nations seeking to harness nuclear energy for peaceful purposes.'' This concept would require nations to choose one of two paths for civilian nuclear development: those that only have reactors and those that contain one or more elements of the nuclear fuel cycle, including recycling. ''Fuel cycle'' states would enrich uranium, manufacture and lease fuel to ''reactor'' states and receive the reactor states' spent fuel. All parties would accede to stringent security and safeguard standards, embedded within a newly invigorated international regime. Reactor states would be relieved of the financial, environmental (and political) burden of enriching and manufacturing fuel and dealing with spent fuel. Fuel cycle states would potentially earn money on leasing the fuel and perhaps on sales of reactors to the reactor states. Such a leasing concept is especially interesting in scenarios which envision growth in nuclear power, and an important consideration for such a nuclear growth regime is the role of recycling of civilian spent fuel. Recycling holds promise for improved management of spent fuel and efficient utilization of resources, but continues to raise the specter of a world with uncontrolled nuclear weapons proliferation. If done effectively, a fuel-leasing concept could help create a political and economic foundation for significant growth of clean, carbon-free nuclear power while providing a mechanism for significant international cooperation to reduce proliferation concern.

2009-06-15

The Proliferation Resistance and Physical Protection (PR and PP) Working Group of the Generation IV International Forum (GIF) conducted a high-level pathway analysis of a hypothetical sodium fast reactor and integral fuel processing facility (called collectively the 'Example Sodium Fast Reactor' or ESFR), as a test of the effectiveness of its analysis methodology. From a common set of assumed host-state capabilities and objectives, a number of threat scenarios emerge (Concealed Diversion, Concealed Misuse, Breakout or Overt Misuse, and Theft/Sabotage). This paper presents the results of the analysis based on the Breakout scenario. A distinguishing aspect of Breakout scenario consideration concerns the optimal use of the time from breakout to weapons readiness, which is related to the Proliferation Time measure. The goal of analyzing the breakout scenario was therefore to complement other analyses involving the Concealed Misuse and Diversion scenarios by exploring the minimum post-breakout time to weapons readiness. Four target strategies were chosen for analysis: (1) Diversion of LEU feed material at front-end of the ESFR facility; (2) Misuse of the reactor facility to irradiate fertile material; (3) Misuse of the reactor facility to irradiate material in the in-core fuel storage basket; and (4) Misuse of the fuel processing facility to higher-purity TRU. The investigation identified several general 'sub-strategies' within the Breakout scenario, dependent upon the aggressiveness with which a State pursues its intent to break out (including its aversion to the risk of detection). The sub-strategy chosen by a proliferant state will affect both the time available and potential complexity for proliferation activities. The sub-strategy chosen is itself affected by political factors (foreign relations agenda of state, probability of external intervention after breakout, external dependence of proliferant state's supply chain, etc.) These factors

Canada's nuclear non-proliferation policy

International Nuclear Information System (INIS)

1985-01-01

Canada's non-proliferation and safeguards policy has two objectives: 1) to promote the emergence of a more effective and comprehensive international non-proliferation regime; and 2) to assure the Canadian people and the international community that Canadian nuclear exports will not be used for any nuclear explosive purpose. By emphasizing the key role of the NPT, by promoting reliance upon and improvements in the IAEA safeguards system, by treating nuclear weapon and non-nuclear weapon states alike regarding Canadian nuclear exports, by working for new approaches covering the sensitive phases (e.g. reprocessing) of the nuclear fuel cycle, Canada's policy promotes attainment of the first objective. The latter objective is served through the network of bilateral nuclear agreements that Canada has put into place with its nuclear partners. Those agreements provide assurance that Canada's nuclear exports are used solely for legitimate, peaceful, nuclear energy production purposes. At the same time, Canada, having formulated its non-proliferation and safeguards policy during the period 1945 to 1980, has recognized that it has gone as far as it can on its own in this field and that from this point on any further changes should be made on the basis of international agreement. The Canadian objective in post-INFCE forums such as the Committee on Assurances of Supply is to exert Canada's best efforts to persuade the international community to devise a more effective and comprehensive international non-proliferation regime into which Canada and other suppliers might subsume their national requirements

Commercial Satellite Imagery Analysis for Countering Nuclear Proliferation

Science.gov (United States)

Albright, David; Burkhard, Sarah; Lach, Allison

2018-05-01

High-resolution commercial satellite imagery from a growing number of private satellite companies allows nongovernmental analysts to better understand secret or opaque nuclear programs of countries in unstable or tense regions, called proliferant states. They include North Korea, Iran, India, Pakistan, and Israel. By using imagery to make these countries’ aims and capabilities more transparent, nongovernmental groups like the Institute for Science and International Security have affected the policies of governments and the course of public debate. Satellite imagery work has also strengthened the efforts of the International Atomic Energy Agency, thereby helping this key international agency build its case to mount inspections of suspect sites and activities. This work has improved assessments of the nuclear capabilities of proliferant states. Several case studies provide insight into the use of commercial satellite imagery as a key tool to educate policy makers and affect policy.

Lone-actor Terrorism and Impulsivity.

Science.gov (United States)

Meloy, J Reid; Pollard, Jeffrey W

2017-11-01

In some recent cases of lone-actor terrorism, there is evidence the subject acted impulsively, often in response to a triggering event which contained a loss and humiliation. Evidence suggests the subjects acted precipitously, despite planning and preparation carried out in the preceding weeks or months, and their attacks failed to include the often considerable preparation that had been done. The pathway became a runway. The authors recommend the traditional assessment of impulsivity in persons of concern for lone acts of terrorism, as well as other proximal warning behaviors for targeted violence. Both indirect and direct assessment guidelines are proposed, with an emphasis upon self-report, psychological testing, collateral data gathering, and historical records. © 2017 American Academy of Forensic Sciences.

Proliferation is a problem that can only be solved when the political problems which lead countries to contemplate, the possession of nuclear weapons are solved; in the meantime it can only be managed. Non-proliferation policy has to deal both with the political and the technical aspects of proliferation. It must seek to buy time by addressing the reasons why nations feel the political need to construct nuclear weapons, as well as delaying the moment when such nations feel capable of doing so. The subject is examined and proposals made. (author)

The INPRO methodology in the area of proliferation resistance (PR) has one basic principle and five user requirements with relevant criteria, indicators, evaluation parameters, etc. The two Korean case studies on proliferation resistance of the DUPIC fuel cycle during 2004 and 2005 and various consultancy meetings have contributed to the establishment of the assessment metrics and procedures for three user requirements regarding States' commitment, attractiveness of nuclear material and technology, and difficulty and detectability of diversion. However, the assessment indicators and procedure for user requirement 4 regarding multiplicity and robustness of barriers against proliferation still need to be developed. In this paper, a systematic approach to identify and analyze the acquisition/diversion pathways in a nuclear energy system is described, including follow-up R and D plans to assess the multiplicity and robustness of barriers against proliferation

1989-01-01

The history of international efforts against horizontal proliferation, including the Baruch Plan, bilateral safeguards agreement, IAEA safeguards, the Nuclear Non-Proliferation Treaty, the Zangger Committee, the Nuclear Supplier Group guidelines and the Physical Protection Convention, is reviewed. The role of IAEA NPT safeguards in verifying nondiversion and ensuring no misuse of supplied nuclear items is discussed. The vital importance of successful performance of this role to peaceful nuclear commerce is stressed. The application of NPT safeguards by the IAEA is described, particularly the IAEA's requirement that a State System of Accounting for and Control of Nuclear Material be established. Such a State System has two different but complementary areas of responsibility - ensuring that the use of nuclear material is controlled effectively and can be readily accounted for (this includes the area of physical protection), and providing accounts of nuclear material to responsible bodies such as the State's government and equally importantly to the IAEA for safeguards purpose, as the IAEA bases its conclusions about diversion on its verification of the data provided by the State System

Gas Centrifuges and Nuclear Proliferation

Energy Technology Data Exchange (ETDEWEB)

Albright, David

2004-09-15

Gas centrifuges have been an ideal enrichment method for a wide variety of countries. Many countries have built gas centrifuges to make enriched uranium for peaceful nuclear purposes. Other countries have secretly sought centrifuges to make highly enriched uranium for nuclear weapons. In more recent times, several countries have secretly sought or built gas centrifuges in regions of tension. The main countries that have been of interest in the last two decades have been Pakistan, Iraq, Iran, and North Korea. Currently, most attention is focused on Iran, Pakistan, and North Korea. These states did not have the indigenous abilities to make gas centrifuges, focusing instead on illicit and questionable foreign procurement. The presentation covered the following main sections: Spread of centrifuges through illicit procurement; Role of export controls in stopping proliferation; Increasing the transparency of gas centrifuge programs in non-nuclear weapon states; and, Verified dismantlement of gas centrifuge programs. Gas centrifuges are important providers of low enriched uranium for civil nuclear power reactors. They also pose special nuclear proliferation risks. We all have special responsibilities to prevent the spread of gas centrifuges into regions of tension and to mitigate the consequences of their spread into the Middle East, South Asia, and North Asia.

The goals of United States non-proliferation policy are to minimize the spread of nuclear weapons and to create a stable international environment for the peaceful use of nuclear energy

Suggested non-proliferation criteria for commercial nuclear fuel cycles

International Nuclear Information System (INIS)

Laney, R.V.; Heubotter, P.R.

1978-01-01

Based on the Administration's policy to prevent nuclear weapons proliferation through diversion of fuel from commercial reactor fuel cycles, a ''benchmark'' set of nonproliferation criteria was prepared for the commercial nuclear fuel cycle. These criteria should eliminate incremental risks of proliferation beyond those inherent in the present generation of low-enriched-uranium-fueled reactors operating in a once-through mode, with internationally safeguarded storage of spent fuel. They focus on the balanced application of technical constraints consistent with the state of the technology, with minimal requirements for institutional constraints, to provide a basis for assessing the proliferation resistance of proposed fission power systems. The paper contains: (1) our perception of the nuclear energy policy and of the baseline proliferation risk accepted under this policy; (2) objectives for a reactor and fuel cycle strategy which address the technical, political, and institutional aspects of diversion and proliferation and, at the same time, satisfy the Nation's needs for efficient, timely, and economical utilization of nuclear fuel resources; (3) criteria which are responsive to these objectives and can therefore be used to screen proposed reactor and fuel cycle strategies; and (4) a rationale for these criteria

Actor-Network Theory and methodology: Just what does it mean to say that nonhumans have agency?

Science.gov (United States)

Sayes, Edwin

2014-02-01

Actor-Network Theory is a controversial social theory. In no respect is this more so than the role it 'gives' to nonhumans: nonhumans have agency, as Latour provocatively puts it. This article aims to interrogate the multiple layers of this declaration to understand what it means to assert with Actor-Network Theory that nonhumans exercise agency. The article surveys a wide corpus of statements by the position's leading figures and emphasizes the wider methodological framework in which these statements are embedded. With this work done, readers will then be better placed to reject or accept the Actor-Network position - understanding more precisely what exactly it is at stake in this decision.

2004-01-01

Based on hearings of experts (notably MR El Baradei, IAEA general manager), and written at the time North Korea admitted the existence of a military nuclear programme and decided to expel IAEA inspectors, and Libya and Iran revealed nuclear activities which had been until then unsuspected, this report aims at discussing events which occurred during the two previous years in relationship with nuclear proliferation. The author first tries to draw some lessons from these recent proliferation crises. In this respect, he outlines that they reveal weaknesses of the international regime of nuclear non proliferation: lack of control means for the NPT, lack of control of the access to fuel cycle technologies, gaps in export controls exacerbated by the emergence of private actors. The author then highlights some dangerous features which threaten international safety: loss of credibility of the NPT as shown by North Korea withdrawing from the NPT without unbearable political cost, current crises with Iran and North Korea having a very strong destabilisation potential, and, with the threat of use of dirty bombs, emergence of relationships between proliferation and terrorism. In the next part, the author discusses how to make the struggle against nuclear proliferation more efficient: need of stronger mobilisation and unity within the international community, solution of the Iranian problem as a priority and a test for the international community, and ways to strengthen this struggle (implementation of additional protocols, necessity of an international framework for the control of activities related to the fuel cycle, and necessity of more visible sanctions for the sake and respect of treaties).

Plutonium Proliferation: The Achilles Heel of Disarmament

International Nuclear Information System (INIS)

Leventhal, Paul

2001-01-01

Plutonium is a byproduct of nuclear fission, and it is produced at the rate of about 70 metric tons a year in the world's nuclear power reactors. Concerns about civilian plutonium ran high in the 1970s and prompted enactment of the Nuclear Non-Proliferation Act of 1978 to give the United States a veto over separating plutonium from U.S.-supplied uranium fuel. Over the years, however, so-called reactor-grade plutonium has become the orphan issue of nuclear non-proliferation, largely as a consequence of pressures from plutonium-separating countries. The demise of the fast breeder reactor and the reluctance of utilities to introduce plutonium fuel in light-water reactors have resulted in large surpluses of civilian, weapons-usable plutonium, which now approach in size the 250 tons of military plutonium in the world. Yet reprocessing of spent fuel for recovery and use of plutonium proceeds apace outside the United States and threatens to overwhelm safeguards and security measures for keeping this material out of the hands of nations and terrorists for weapons. A number of historical and current developments are reviewed to demonstrate that plutonium commerce is undercutting efforts both to stop the spread of nuclear weapons and to work toward eliminating existing nuclear arsenals. These developments include the breakdown of U.S. anti-plutonium policy, the production of nuclear weapons by India with Atoms-for-Peace plutonium, the U.S.-Russian plan to introduce excess military plutonium as fuel in civilian power reactors, the failure to include civilian plutonium and bomb-grade uranium in the proposed Fissile Material Cutoff Treaty, and the perception of emerging proliferation threats as the rationale for development of a ballistic missile defense system. Finally, immobilization of separated plutonium in high-level waste is explored as a proliferation-resistant and disarmament-friendly solution for eliminating excess stocks of civilian and military plutonium.

Fissile material proliferation risk

Dreicer, J.S.; Rutherford, D.A.

1996-01-01

The proliferation risk of a facility depends on the material attractiveness, level of safeguards, and physical protection applied to the material in conjunction with an assessment of the impact of the socioeconomic circumstances and threat environment. Proliferation risk is a complementary extension of proliferation resistance. The authors believe a better determination of nuclear proliferation can be achieved by establishing the proliferation risk for facilities that contain nuclear material. Developing a method that incorporates the socioeconomic circumstances and threat environment inherent to each country enables a global proliferation assessment. To effectively reduce the nuclear danger, a broadly based set of criteria is needed that provides the capability to relatively assess a wide range of nuclear related sites and facilities in different countries and still ensure a global decrease in proliferation risk for fissile material (plutonium and highly enriched uranium)

Initiatives for proliferation prevention

International Nuclear Information System (INIS)

1997-04-01

Preventing the proliferation of weapons of mass destruction is a central part of US national security policy. A principal instrument of the Department of Energy's (DOE's) program for securing weapons of mass destruction technology and expertise and removing incentives for scientists, engineers and technicians in the newly independent states (NIS) of the former Soviet Union to go to rogue countries or assist terrorist groups is the Initiatives for Proliferation Prevention (IPP). IPP was initiated pursuant to the 1994 Foreign Operations Appropriations Act. IPP is a nonproliferation program with a commercialization strategy. IPP seeks to enhance US national security and to achieve nonproliferation objectives by engaging scientists, engineers and technicians from former NIS weapons institutes; redirecting their activities in cooperatively-developed, commercially viable non-weapons related projects. These projects lead to commercial and economic benefits for both the NIS and the US IPP projects are funded in Russian, Ukraine, Kazakhstan and Belarus. This booklet offers an overview of the IPP program as well as a sampling of some of the projects which are currently underway

Scholars in the Nineties: Actors, Subjects, Spectators or Hostages?

Directory of Open Access Journals (Sweden)

Manuel Gil Antón

2000-05-01

Full Text Available Dr. Gil questions the role played by Mexican university academics in the transformation of higher education during the nineties. After outlining the general context of change and its importance, the author proposes avoiding the false dichotomy between restoring the past or installing, without reflective mediation, a schematic future. He suggests taking into consideration the current national academic body composed of several generations of scholars. Three phases are established in terms of the modification of academic activities during the last decades of the twentieth century, and the changes in the level of higher education are considered. Dr. Gil asks if the academics have been actors, subjects, spectators or hostages-both in regard to regulations governing their activity and in the modifications of university processes and structure. The essay ends by proposing a general agenda for research in the field of university studies, and emphasizes two problems: the need for a detailed description of the type and depth of changes, and the definition of the academic as a central actor in institutional life.

A first set of article comments and discusses the various stakes and challenges of the 21. Conference of Parties (COP 21): the negotiation process which resulted in a synthesis which is to be signed by 95 States in Paris, the elaboration of an Agenda of solutions with the commitment of enterprises and local authorities, the issue of international financing as some promises remained not kept for the support to adaptation of developing countries. A second set of articles addresses the involved actors and their technological or economic challenges: the needed evolution of energy (electricity, heat, gas, fuel) producers away from fossil energies to reduce greenhouse gas emissions, the strategy of the French company Engie in the field of photovoltaic, wind and more generally renewable energies, innovating trends of decentralisation of energy production (offshore wind energy, hydrogen, plasma torch, flexible photovoltaic arrays, the wind tree, the floating wind turbine, new technologies for solar arrays), the perspectives for industrial sectors concerned by energy transition (with the example of Schneider Electric), emerging technologies (oil lamp, new boilers, desalination equipment, storage of wind energy, co-generation), developments and perspectives in the transport sector (example of Renault, new technologies for hybrid propulsion, bio-refineries, reduction of fuel consumption, hybrid aircraft, and heat management in railways) and in the building sector (new standards and applications, new building materials). A last article outlines the threat that climate can be for profitability and the taking of the carbon risk into account by the insurance and financial sectors

Social network analysis via multi-state reliability and conditional influence models

Schneider, Kellie; Rainwater, Chase; Pohl, Ed; Hernandez, Ivan; Ramirez-Marquez, Jose Emmanuel

2013-01-01

This paper incorporates multi-state reliability measures into the assessment of a social network in which influence is treated as a multi-state commodity that flows through the network. The reliability of the network is defined as the probability that at least a certain level of influence reaches an intended target. We consider an individual's influence level as a function of the influence levels received from preceding actors in the network. We define several communication functions which describe the level of influence a particular actor will pass along to other actors within the network. Illustrative examples are presented, and the network reliability under the various communication influence levels is computed using exhaustive enumeration for a small example and Monte Carlo simulation for larger, more realistic sized examples.

Argentina’s nuclear development and the non-proliferation regime

Full Text Available The development and transfer of nuclear technology have been put under strict control due to its possible military use, leading to the creation of international non-proliferation regimes. One of the latest proposals was the creation of multilateral banks of low enriched uranium (leu. The article states that, under the goal of non-proliferation, this initiative can contribute to accentuate the asymmetry in the distribution of world economic and political power, damaging the endogenous development of this technology in emerging countries. Against this, the article investigates the existence of margins to maneuver in the international system from the case of study of Argentina, one of the few developing countries that have managed to export nuclear technology, and has declared the development of independent nuclear activity as a State policy

Multi-actor involvement for integrating ecosystem services in strategic environmental assessment of spatial plans

2017-01-01

Integrating an ecosystem services (ES) approach into Strategic Environmental Assessment (SEA) of spatial plans potentially enhances the consideration of the value of nature in decision making and policy processes. However, there is increasing concern about the institutional context and a lack of a common understanding of SEA and ecosystem services for adopting them as an integrated framework. This paper addresses this concern by analysing the current understanding and network relations in a multi-actor arrangement as a first step towards a successful integration of ES in SEA and spatial planning. Our analysis focuses on a case study in Chile, where we administered a questionnaire survey to some of the main actors involved in the spatial planning process. The questionnaire focused on issues such as network relations among actors and on conceptual understanding, perceptions and challenges for integrating ES in SEA and spatial planning, knowledge on methodological approaches, and the connections and gaps in the science-policy interface. Our findings suggest that a common understanding of SEA and especially of ES in a context of multiple actors is still at an initial stage in Chile. Additionally, the lack of institutional guidelines and methodological support is considered the main challenge for integration. We conclude that preconditions exist in Chile for integrating ES in SEA for spatial planning, but they strongly depend on appropriate governance schemes that promote a close science-policy interaction, as well as collaborative work and learning. - Highlights: • Linking ecosystem services in SEA is an effective framework for sustainability. • Multi-actor understanding and networks in ecosystem services and SEA were analyzed. • Understanding of SEA and especially of ES is still in an initial stage in Chile. • A lack of institutional guidelines is one of the key challenges for this link.

Anthropology in the post-Euclidean State, or from textual to oral anthropology

Directory of Open Access Journals (Sweden)

Antonio Luigi Palmisano

2011-12-01

Full Text Available The actual crisis of anthropology is examined in relation to its wide public success. Anthropology has prospered and the anthropologists have proliferated becoming more specific. But the theoretical debate has come to a halt over the last decades. The article suggests that both the methodology and the form of expression of the ethnographic report have developed and then become crystallized around actual protocols. A critique of the dichotomy Subject/Object, namely the key discussion about the notion of Otherness, is here reexamined as the testimony for an immanent “non-protocolar” character of anthropology. This critique together with the end of anthropology as tekhne, i.e. as protocolar activity, will allow anthropology to go on enhancing many other social and non social sciences. The article discusses the re-definition of anthropology in the context of Daseinanalysis and, therefore the changing relation between man and power, that is between the social actor and the post-Euclidean State in the era of the tekhne.

Understanding the complex relationships among actors involved in the implementation of public-private mix (PPM) for TB control in India, using social theory.

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

Nuclear non-proliferation: failures and prospects

Imai, R.; Press, R.

1980-01-01

The objective of this paper is to examine the evolution of combined political and technical attempts to achieve worldwide acceptance of a commitment to non-proliferation, to note failures to date, and to identify essential factors to be satisfied if greater and necessary success is to be achieved in the immediate future. For this it is necessary to separate the realism and unrealism so often involved in discussing the concept of non-proliferation, as defined above, particularly if treated as a moral principle rather than as part of a general security issue reflecting shifts in regional and global stability. The political nature of the non-proliferation problem is underlined by the fact that whereas five nuclear weapon states are currently accepted, any threatened increase in that number is discouraged by every possible peaceful means. This fact combines political acceptance of an existing international situation with a belief that any addition to the present number must lead to international instability. Success in preventing additions may be more readily achieved through political understanding and perhaps some compromises, in particular cases, rather than through seeking a universal solution to a generalized problem

Pork safety is an important public health concern in Vietnam and is a shared responsibility among many actors along the pork value chain. We examined the knowledge, perceptions, and practices regarding food safety, disease, and health risk among selected pork value chain actors (slaughterhouse owners and workers, people living around slaughterhouses, pork sellers, consumers, and veterinary and public health staff) in three districts in Hung Yen Province, Vietnam. We randomly selected 52 pork value chain actors to be surveyed through questionnaires, observation checklists, key informant interviews, and focus group discussions. Most slaughterhouse workers acquired knowledge and experience of food safety through "learning by doing" rather than from training by a veterinary or public health professional. Both slaughterhouse worker and pork seller groups had some accurate perceptions about pig diseases and foodborne diseases; however, misperceptions of risk and, especially, of zoonoses were present. Furthermore, while workers and sellers often use cloths to dry the meat and clean equipment, they did not think this was a risk for meat contamination. Moreover, when sellers wear protective equipment, such as gloves, masks, or hats, consumers perceive that the sellers may have health issues they are trying to conceal and so consumers avoid buying from them. The perceived freshness of pork, along with trust in the seller and in the pork production process, were strong indicators of consumer preference. And yet, pork value chain actors tend to trust their own individual food safety practices more, rather than the practices of other actors along the chain. Veterinary and public health staff emphasized the gap between regulations and food safety practices. Education and training on food safety risks and proper handling are priorities, along with integrated and intensive efforts to improve food safety among pork value chain actors.

The population-development tangle. Aspects and actors.

Sen, G

1993-01-01

Since the 1974 Population Conference, the population field has become of interest to members of the fundamentalist right wing, feminists, and environmentalists. Therefore, it is necessary to understand the areas of agreement and disagreement among each set of actors as well as how they define the issues. Currently, development discourse is characterized by considerations of: 1) economic growth, 2) the provision of livelihoods, 3) the provision of basic needs, 4) ecological sustainability and renewability, and 5) political participation. The actors who define the terms of this discourse include: 1) corporate interests, which concentrate on economic growth; 2) international and national agencies, which place primary importance on economic growth and some importance on basic needs and ecological sustainability; 3) popular organizations and social movements, which concentrate on livelihoods, basic needs, and political participation; and 4) environmentalists, who focus on ecological sustainability, economic growth, and (occasionally) political participation. The field of population, on the other hand, is dominated by traditional populationists, whose primary focus is economic growth; developmentalists; the fundamentalist right, who are most concerned with family and control over reproduction; environmentalists; and the women's movement, which is most concerned with reproductive rights and reproductive health. When the perspective of poor women is considered, it can be seen that economic growth and ecological sustainability must support the securing of livelihoods, basic needs, political participation, and reproductive rights, and that reproductive health programs must be part of an overall health agenda.

U.S. - India nuclear cooperation and non-proliferation

The agreement for cooperation between the Government of the United States of America and the government of India concerning peaceful uses of nuclear energy (referred as 123 agreement) acknowledges a shift in international strategies and relations in both countries. As to India, it marks the end of nuclear isolation resulting from constraint, embargoes and controls and instead opens the path for nuclear commerce. With respect to the United States it entails a major geo strategic ally in the evolving South Asia region and promises large commercial benefits to the US nuclear sector. This is called 'nuclear deal' and constitutes one of the major political, economic and strategic relationship developing between the two countries since 2001. It will lead to the separation of military and civilian nuclear installations in India, the latter to be placed under the safeguards system of the International Atomic Energy Agency (IAEA). It thus, de facto accepts India in the club of nuclear weapon states within the meaning of the Treaty on the non-proliferation of nuclear weapons (NPT) although it is not party to this treaty, refuses adhering to it, officially possesses nuclear weapons and is not subject to a comprehensive system of safeguards. This article will examine the developments which led to the 123 agreement and its subsequent implementation in a wider context of international relations and non proliferation. First, the articles gives a brief introduction into the Indian nuclear programme, the legislative framework and the factors which necessitated nuclear cooperation between India and the United States. Secondly, it will address the implementation of the nuclear deal and subsequent developments. Finally, it will analyse the non proliferation issues related to the implementation of the agreement.

The 1970 Treaty on the Non-Proliferation of Nuclear Weapons (NPT), with 188 States party, represents the cornerstone of the global nuclear non-proliferation and disarmament effort - and despite recent challenges, it has never been more relevant than it is today. But the international community has to move forward, it is essential that a number of the basic assumptions should be revisited, and a number of new approaches reconsidered. A key assumption at the core of the NPT was that the asymmetry between nuclear-weapon States and non-nuclear-weapon States would gradually disappear. The nuclear non-proliferation regime has overall been successful - but with some shortcomings. Efforts to end nuclear weapons development achieved an important milestone with the conclusion of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) in September 1996, but the pace of progress has been sluggish among the 44 countries whose ratification is required for the treaty to enter into force - and the rejection of the CTBT by the US Senate in 1999 was a distinct setback. Negotiation of a Fissile Material Cut-Off Treaty (FMCT) continues to languish in Geneva, more than seven years after agreement was reached on a mandate. The 2000 NPT Review Conference, building on the package of decisions and resolutions that led to the indefinite extension of the NPT in 1995, resulted in a number of encouraging commitments, not least the 'unequivocal undertaking' by the nuclear-weapon States to accomplish the total elimination of their nuclear arsenals. But a scant two years later, we have moved sharply away from those commitments, with a number of the '13 steps' toward nuclear disarmament - such as 'irreversibility,' 'START II, START III and the ABM Treaty,' further 'unilateral' reductions in nuclear arsenals, 'increased transparency,' 'further reduction of non-strategic nuclear weapons,' and 'regular reports' on the implementation of Article VI of the NPT - left without concrete follow-up actions and in

Nuclear proliferation: present, past and future

Since the end of WW II one of the more, if not the most, serious concerns of all people in the world has been to preserve this planet avoiding a nuclear war. On the positive side, in spite of the huge arsenal of strategic and tactical nuclear weapons (NW) accumulated over the years by the US and the former SU and the innumerable military conflicts we have witnessed since WW II, no NW have been used again. But this should not be a great consolation: the fact that countries have refrained from using NW does not necessarily mean that it will always be that way. As long as countries try to solve their differences by the use of force the danger of a nuclear confrontation remains, and nuclear disarmament and proliferation should cotinue to be a serious concern. This concern has profound political, social and ethical components that have been analyzed extensively and profusely. The purpose of this paper is more limited: to provide an overview of the national and international efforts to minimize the risk of a nuclear war by regulating, restricting and containing the development and possession of NW. This is what has become know as the nuclear non-proliferation regime. Any nuclear non-proliferation regime must have two essential goals: achieving nuclear disarmament by the NWS (and thereby eliminating vertical proliferation). To make a regime effective it must rely on international agreements, a system of safeguards coupled with inspection and verification procedures, and above all on the good faith of all nations involved. It should be stated from the very beginning that nuclear non-proliferation efforts, like all disarmament efforts, are essentially of political nature, albeit having an important scientific and technological component. They are effective only to the extent that countries really renounce NW and are prepared to severely sanction those who do not. (Author) 31 refs

The role of growth factors (GFs) in controlling the biology of human hematopoietic stem cells (HSCs) remains limited by a lack of information concerning the individual and combined effects of GFs directly on the survival, Mitogenesis, and regenerative activity of highly purified human HSCs. We show that the initial input HSC activity of such a purified starting population of human cord blood cells can be fully maintained over a 21-day period in serum-free medium containing five GFs alone. HSC survival was partially supported by any one of these GFs, but none were essential, and different combinations of GFs variably stimulated HSC proliferation. However, serial transplantability was not detectably compromised by many conditions that reduced human HSC proliferation and/or survival. These results demonstrate the dissociated control of these three human HSC bio-responses, and set the stage for future improvements in strategies to modify and expand human HSCs ex vivo.

Bullying is a national problem for families, courts, schools, and the economy. Social, educational, and professional lives of victims are affected. Early detection of bullies mitigates destructive effects of bullying. Our previous research found, given specific characteristics of an actor, actor logics can be developed utilizing input from natural language processing and graph analysis. Given similar characteristics of cyberbullies, in this paper, we create specific actor logics and apply these to a select social media dataset for the purpose of rapid identification of cyberbullying.

Full Text Available The aim of the paper is to map the area where the social construction of age discrimination in the recruiting process is perceived as taking place, especially those individuals or organized groups with enough power and interest to influence this unethical reality. The research was carried out in 2010 and 2011 in Cluj-Napoca, Romania; it uses multiple qualitative methods (focus-group and interviews and covers three layers of perception: candidate’s perception, employer’s perception and recruiter’s perception. Usually, the main social actors publically perceived as influencing age discrimination in the recruiting process are the employers (as the main responsible, some public institutions (as guardians and the candidates (as victims. The findings of the paper show that the number of social actors perceived as interested and with power by the main social actors (employers and candidates is much higher than the number classically targeted by researchers, reaching 20 or more

Action recognition is sensitive to the identity of the actor.

Recognizing who is carrying out an action is essential for successful human interaction. The cognitive mechanisms underlying this ability are little understood and have been subject of discussions in embodied approaches to action recognition. Here we examine one solution, that visual action recognition processes are at least partly sensitive to the actor's identity. We investigated the dependency between identity information and action related processes by testing the sensitivity of neural action recognition processes to clothing and facial identity information with a behavioral adaptation paradigm. Our results show that action adaptation effects are in fact modulated by both clothing information and the actor's facial identity. The finding demonstrates that neural processes underlying action recognition are sensitive to identity information (including facial identity) and thereby not exclusively tuned to actions. We suggest that such response properties are useful to help humans in knowing who carried out an action. Copyright © 2017 The Author(s). Published by Elsevier B.V. All rights reserved.

Expectations as a key to understanding actor strategies in the field of fuel cell and hydrogen vehicles.

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.

Baca, T.E.; Scudella, G.

1978-01-01

New Mexico can expect to see an accelerated development of its uranium resources. The President's policy on non-proliferation will impact the degree and quantity of uranium ore mined. Environmental impacts are significant and are affected by the mining and milling phase more than any other aspect of the uranium fuel cycle. The state has begun evaluating the resource-associated impacts of uranium mining and milling, although very little reliable data are available. The information gathered, however, shows a need for state and Federal evaluation of both the impacts and the non-proliferation policy. 4 references

Towards State Hegemony Over Agricultural Certification: From Voluntary Private to Mandatory State Regimes on Palm Oil in Indonesia

Full Text Available Previous work on certification of palm oil has reported on a trend toward a change, from failed state regulation to voluntary, private governance. However, recent observations suggest a trend, moving from voluntary, private governance to mandatory state governance in palm oil certification in Indonesia, a move in which the state is reclaiming authority.In thislight, the aims of ourresearch are (1 to identify the main actorsinvolved in certification politics, (2 to explain this trend in terms of the actors' interests and whatever benefits may result for them. We developed our research questions based on bureaucratic politics and power theory. A mix of document analysis, interviews, and observations are applied for addressing the questions. The results answer our research questions, i.e., that (1 the state claims back its authority over certification from private actors and contributed to the complex meta governance of palm oil certification, the state mandatory scheme that is supported by states' bureaucracies in charge reducesthe influence of non-government or private actors. (2 Thistrend is due to a coalition ofspecific state bureaucracies and big industry interests, which grant privileges to industry that are denied to small producers. Unexpectedly, all Indonesian bureaucracies associated with this trend support mandatory state certification, which indicates that palm oil has been elevated in importance to become a matter of national, rather than mere bureaucratic interest.Making certificationmandatory through coercive regulatory poweristhe main toolwithwhich state power can challenge voluntary implementation and reclaim authority. Furthermore, the state needs the voluntary system to exist as well in order to strengthen its position. Therefore, the voluntary and the compulsory systems collaborate to attract global initiatives,which is contributing to the high complex of meta governance.

[Social and political actors in the formulation of health reform in Spain].

Etviti, J E; Leyva, R F

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.

MYC through miR-17-92 Suppresses Specific Target Genes to Maintain Survival, Autonomous Proliferation, and a Neoplastic State

The MYC oncogene regulates gene expression through multiple mechanisms, and its overexpression culminates in tumorigenesis. MYC inactivation reverses turmorigenesis through the loss of distinguishing features of cancer, including autonomous proliferation and survival. Here we report that MYC via miR-17-92 maintains a neoplastic state through the suppression of chromatin regulatory genes Sin3b, Hbp1, Suv420h1, and Btg1, as well as the apoptosis regulator Bim. The enforced expression of miR-17-92 prevents MYC suppression from inducing proliferative arrest, senescence, and apoptosis and abrogates sustained tumor regression. Knockdown of the five miR-17-92 target genes blocks senescence and apoptosis while it modestly delays proliferative arrest, thus partially recapitulating miR-17-92 function. We conclude that MYC, via miR-17-92, maintains a neoplastic state by suppressing specific target genes.

The world's non-proliferation regime in time

members to countries that need assistance in order to provide better security for nuclear material in their possession, to an April 2004 Security Council resolution that requires countries having nuclear materials to protect them in various ways from being acquired by 'non-State actors' such as terrorists. The regime includes prohibitions on testing such as the 1963 Limited Test Ban Treaty and the 1996 Comprehensive Test Ban Treaty. The first prohibits nuclear weapons tests everywhere but underground, and the second will prohibit them even underground if it goes into force. For the large majority of NPT members not having nuclear weapons, these treaties contribute to non-proliferation not just by inhibiting testing but by reducing the discrimination inherent in the NPT between those permitted to have nuclear weapons and those not so permitted. These members see an agreement to stop testing by the P-5 as a step of compliance by the P-5 with their NPT promise to cease the nuclear arms race, reduce their nuclear weapons and move toward nuclear disarmament. The regime includes 'no-first-use promises' by the P-5 to other NPT members, usually called 'negative security assurances.' All of the P-5 but China have stated some exceptions to these promises. (The US exception permits use of nuclear weapons against a non-nuclear-weapon NPT member if it attacks another non-weapon NPT member while the attacker is in alliance with a State having nuclear weapons. Recently, the United States asserted another exception by saying it might use nuclear weapons to counter a biological or chemical attack.) The regime includes promises by the P-5 that some protection will be provided to other NPT members in the event of a threat of attack, promises called 'positive security assurances.' The P-5 have promised to seek immediate UN Security Council orders providing security assistance to any NPT member not having nuclear weapons if it is threatened with attack by another nation's nuclear weapons.

Hafemeister, David

2016-01-01

This book fills a clear gap in the literature for a technically-focused book covering nuclear proliferation and related issues post-9/11. Using a concept-led approach which serves a broad readership, it provides detailed overview of nuclear weapons, nuclear proliferation and international nuclear policy. The author addresses topics including offensive and defensive missile systems, command and control, verification, weapon effects, and nuclear testing. A chronology of nuclear arms is presented including detailed discussion of the Cold War, proliferation, and arms control treaties. The book is tailored to courses on nuclear proliferation, and the general reader will also find it a fascinating introduction to the science and strategy behind international nuclear policy in the modern era. “Finally, a spritely, accessible overview of the nuclear world in historical context from someone who has both seen it from the U.S. State Department and Congressional policy trenches and taught it for 43 years.

On the non-proliferation framework of Japan's peaceful nuclear utilization program

International Nuclear Information System (INIS)

Kano, Takashi

1996-01-01

The Conference of the States Party to the Treaty on the Non-proliferation of Nuclear Weapons (hereinafter referred to as the NPT) convened in New York, from April 17 to May 12, 1995 and decided that the NPT shall continue in force indefinitely, after reviewing the operation and affirming some aspects of the NPT, while emphasizing the ''Decision on Strengthening the Review Process'' for the NPT and the ''Decision on Principles and Objectives for Nuclear Non-proliferation and Disarmament,'' also adopted by the Conference. In parallel, Japan made its basic non-proliferation policy clear in the ''Long-Term Program for Research, Development and Utilization of Nuclear Energy'' which was decided by the Atomic Energy Commission (chaired by Mikio Oomi, then Minister of the Science and Technology Agency of Japan) in June 1994. The Long-Term Program discusses various problems facing post-Cold-War international society and describes Japan's policy for establishing international confidence concerning non-proliferation. This paper summarizes Japan's non-proliferation policy as articulated in the Long-Term Program, and describes some results of an analysis comparing the Long-Term Program with the resolutions on the international non-proliferation frameworks adopted by the NPT conference

The Power Reconfiguration and Global Governance with and Without Government: A View on The New Actors

Directory of Open Access Journals (Sweden)

Giovanni Olsson

2015-12-01

Full Text Available This article aims to address the reconfiguration of the exercise of power and governance by new international actors. Initially, the power is identified in both conflictual relations as in consensual, presenting him with a bifronte categorization: power on and power to. Still, it is the conceptual shift that involves governance, showing that the authority may be exercised independently of the will of States, presenting it as governance with and without government. Finally, it is shown that the new players, especially non-governmental organizations and transnational corporations exert significant role in the political landscape of contemporary international society, whose national borders have every day lost importance.

Actor-networking ceta-sociality, or, what is sociological about contemporary whales?

theory (ANT) allows for the inclusion of non-human ‘actants' (like whales) into the fabric of sociality. In the ontology of ANT, sociality emerges as semiotic-material configurations of humans, animals and technologies. Starting from a critical review of the work by Adrian Franklin on growing......In contemporary urban Euro-American societies, whales have become hugely popular and iconic creatures, arousing controversies more intense than most other instances of animal politics. How to account sociologically, however, for the dramatic social transformation of whales, from natural resource...... to near-sacrosanct agent, is far from self-evident. This article advocates a change of theoretical perspective, inspired by the work of actor-network theorists Bruno Latour and Michel Callon. Rather than focussing solely on the ‘humanity' of human-animal relations, as does most of sociology, actor-network...

Current political discussions and developments indicate the importance and urgency of incorporating climate change considerations into EIA processes. The recent revision of the EU Directive 2014/52/EU on Environmental Impact Assessment (EIA) requires changes in the EIA practice of the EU member states. This paper investigates the extent to which the Environmental Impact Assessment (EIA) can contribute to an early consideration of climate change consequences in planning processes. In particular the roles of different actors in order to incorporate climate change impacts and adaptation into project planning subject to EIA at the appropriate levels are a core topic. Semi-structured expert interviews were carried out with representatives of the main infrastructure companies and institutions responsible in these sectors in Austria, which have to carry out EIA regularly. In a second step expert interviews were conducted with EIA assessors and EIA authorities in Austria and Germany, in order to examine the extent to which climate-based changes are already considered in EIA processes. This paper aims to discuss the different perspectives in the current EIA practice with regard to integrating climate change impacts as well as barriers and solutions identified by the groups of actors involved, namely project developers, environmental competent authorities and consultants (EIA assessors/practitioners). The interviews show that different groups of actors consider the topic to different degrees. Downscaling of climate change scenarios is in this context both, a critical issue with regards to availability of data and costs. Furthermore, assistance for the interpretation of relevant impacts, to be deducted from climate change scenarios, on the specific environmental issues in the area is needed. The main barriers identified by the EIA experts therefore include a lack of data as well as general uncertainty as to how far climate change should be considered in the process without

Exploring the Iran-Hezbollah Relationship: A Case Study of how State Sponsorship affects Terrorist Group Decision-Making

Marc R. DeVore

2012-10-01

Full Text Available Understanding the impact of state sponsorship on the decision-making of violent non-state actors is among the more important issues to scholars of security studies. This article addresses the issue by examining the relationship between Iran and Lebanon’s Hezbollah. To preview its conclusions, there are two main perspectives to consider with regard to the terrorist group – state sponsor relationship. First, state support has a powerful, yet indirect effect on violent non-state actor decision-making by shaping the options available to groups’ leaders.  Second, state sponsors can also directly leverage their aid to shape the strategic decisions of armed non-state actors, forcing their clients to either expand or restrict their activities. Because of inevitable lacunae and contradictions amongst published accounts, this study relies heavily upon primary sources and data collected during field research in Lebanon, including interviews with leaders from Hezbollah, the Lebanese Army, the United Nations' Peacekeeping Mission in Southern Lebanon (UNIFIL and the rival Shia organization, Amal.

It demonstrates that such guarantees have proven to be a very effective instrument in preventing States from going nuclear. It would thus seem logical to reinforce or extend them. However, this path is fraught with obstacles and dilemmas

The ambivalent relation between state and illegal actors: piracy retail in Mexico A relação ambígua entre o Estado e os atores ilegais: o mercado da pirataria no México

Directory of Open Access Journals (Sweden)

José Carlos G. Aguiar

2011-02-01

Full Text Available In the rise of democratic governments across Latin America, the neoliberal law-and-order perspective has been the most influential model of security in the region. This approach is based on the opposition between state and illegal agents, as if they were two different sets of actors. Influenced by this model, Mexican president Vicente Fox launched an extensive anti-piracy programme to eradicate retail of counterfeit. Based on ethnographic material gathered in the San Juan de Dios market in Guadalajara, I discuss on the exchanges between piracy sellers and police officers. My argument is that law enforcement programmes have not affected the political economy of corruption, they overlook the net of ambiguous loyalties where state and illegal actors are entrenched. The anthropology of the state provides the rationale for a critique on neoliberal security policies.Quando surgiram os governos democráticos na América Latina, a perspetiva neoliberal da lei e da ordem constituiu-se como o modelo de segurança dominante na região. Esta abordagem baseia-se na oposição entre o Estado e os agentes da ilegalidade, como se fossem dois conjuntos de atores distintos. Influenciado por este modelo, o presidente mexicano Vicente Fox lançou um programa alargado contra a pirataria, pretendendo erradicar a venda da contrafação. A partir de material etnográfico recolhido no mercado de San Juan de Dios, em Guadalajara, examino as interações entre vendedores de mercadoria pirata e agentes da polícia. Argumento que os programas para a aplicação da lei não afetaram a economia política da corrupção e que ignoram a rede de lealdades ambíguas que envolvem o Estado e os atores ilegais. A antropologia do Estado oferece os princípios para uma crítica sobre as políticas de segurança neoliberais.

History, framework and perspectives of international policy for preventing the proliferation of nuclear weapons

Czakainski, M.

1985-12-01

The study analyses the framework conditions, such as the Non-Proliferation Treaty and the international non-proliferation regime and their interlacement with international nuclear energy policies, and evaluates the results achieved so far on an international level by the efforts directed towards preventing the proliferation of nuclear weapons. The conclusion to be drawn as stated by the author is that the classical tool of non-proliferation policy - denial of technology transfer - will lose in importance and give way to enhanced, controlled cooperation between countries of the Third World and the industrialised countries. Another instrument that will maintain its value for non-proliferation policy is cooperation for political stabilisation in those parts of the world where regional conflicts might aggravate.

Full Text Available Building A creative Barcelona: new actors, new strategies.Barcelona is under the international spotlight. The city that triumphed with the organisation of the Olympic Games in 1992 now wants to become a 21st Century creative city. In order to achieve this goal, the city must establish conditions that facilitate the emergence of a shared discourse around its ability to become an attractive city for creative talent and for businesses. The recognition of the historical-economic heritage, as a starting point for the creative city, along with the driving role played by culture in the generation of a exclusive and distinctive experience, turnBarcelona into a unique city. However, this is not sufficient. The participation and involvement of all the actors in a shared strategy pose significant challenges to Barcelona, as does the need to minimise the negative effects that inevitably accompany success. Companies, institutions and citizens constitute the city’s best assets: they must work in partnership and take advantage of the synergies generated amongst them. Consensus and participation are more than mere utopias in Barcelona: they have become requirements for the city of tomorrow. Moreover, leadership in Barcelona is largely left to public initiative: the emergence of linkages across the needs of the various creative sectors, based on public intervention mechanisms is the best way to ensure success.

Uncovering the most effective active ingredients of antismoking public service announcements: the role of actor and message characteristics.

Shadel, William G; Fryer, Craig S; Tharp-Taylor, Shannah

2009-05-01

This study examined whether the appeal of actors (i.e., their likeability and attractiveness) used in antismoking public service announcements (PSAs) interacts with adolescents' risk of future smoking to predict adolescents' smoking resistance self-efficacy and whether the antismoking messages in the PSAs further moderate this relationship. We used a 2 (future smoking risk: low, high) x 2 (actor appeal: low, high) x 3 (PSA antismoking message: tobacco industry manipulation, short-term smoking effects, long-term smoking effects) study design. A diverse sample of 110 adolescents (aged 11-17 years), with varying levels of experience with smoking, rated their smoking resistance self-efficacy after viewing each of the PSAs in each design cell. Overall, PSAs that used long-term smoking effects messages were associated with the strongest smoking resistance self-efficacy, followed in turn by PSAs that used short-term smoking effects messages and by tobacco industry manipulation messages. We found a significant interaction of actor appeal and PSA antismoking message. The use of more appealing actors was associated with stronger smoking resistance self-efficacy only in long-term smoking effects PSAs. The use of less appealing actors was associated with stronger smoking resistance self-efficacy for tobacco industry manipulation PSAs and short-term smoking effects PSAs. Future smoking risk did not moderate any of these findings. Antismoking PSAs that emphasize long-term smoking effects are most strongly associated with increased smoking resistance self-efficacy. The effect of these PSAs can be strengthened by using actors whom adolescents perceive to be appealing.
