    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.

    Enterprise systems management (ESM) and business process management (BPM), although highly correlated, have evolved as alternative approaches to operational transformation. As a result, companies struggle to find the right balance when prioritizing technology and processes as change drivers....... The purpose of this paper is to propose a direction towards aligning the process-centric and technology-centric approaches. Using the case study method, we gain insight into two implementation projects: one of an information technology (IT) system and one of a process. We compare them using design thinking...... and strategic alignment theories. Based on the discussion, we assess the shortcomings of the process-centric and technology-centric approaches and argue that a conjoint design approach is required to achieve alignment between processes and technology. From a theoretical stance, this paper offers design-informed...

  4. EVALUATING A CUSTOMER-CENTRIC APPROACH

    2007-01-01

    Full Text Available Customer focus is, at best, only one element of the relationship between a company and its customers. At worst it is a board-room buzzworld, witch makes every board member feel a little more secure. Not unlike the phrase “working towards equal opportunities”, it is showing an awareness of a need but is not addressing the issues. Customer focus must lead to something meaningful, will probably require sacrifices and is just one of the steps necessary to become truly customer-centric. A customer focus puts your customers high on your list of priorities. When you put your customers into the heart of your business, make customers part of the culture, then you to become customer-centric.

    Full Text Available The rapid adoption of video gaming among children has placed tremendous strain on parents’ ability to manage their children’s consumption. While parents refer online to video games ratings (VGR information to support their mediation efforts, there are many difficulties associated with such practice. This paper explores the popular VGR sites, and highlights the inadequacies of VGRs to capture the parents’ concerns, such as time displacement, social interactions, financial spending and various video game effects, beyond the widespread panics over content issues, that is subjective, ever-changing and irrelevant. As such, this paper argues for a shift from content-centric to a parent-centric approach in VGRs, that captures the evolving nature of video gaming, and support parents, the main users of VGRs, in their management of their young video gaming children. This paper proposes a Video Games Repository for Parents to represent that shift.

  6. A Probabilistic, Facility-Centric Approach to Lightning Strike Location

    Huddleston, Lisa L.; Roeder, William p.; Merceret, Francis J.

    2012-01-01

    A new probabilistic facility-centric approach to lightning strike location has been developed. This process uses the bivariate Gaussian distribution of probability density provided by the current lightning location error ellipse for the most likely location of a lightning stroke and integrates it to determine the probability that the stroke is inside any specified radius of any location, even if that location is not centered on or even with the location error ellipse. This technique is adapted from a method of calculating the probability of debris collisionith spacecraft. Such a technique is important in spaceport processing activities because it allows engineers to quantify the risk of induced current damage to critical electronics due to nearby lightning strokes. This technique was tested extensively and is now in use by space launch organizations at Kennedy Space Center and Cape Canaveral Air Force Station. Future applications could include forensic meteorology.

  9. An Audience-Centric Approach for Museums Sustainability

    Directory of Open Access Journals (Sweden)

    Laura Di Pietro

    2014-08-01

    Full Text Available The main purpose of this study is to propose a visitor centric perspective that can support museums towards sustainability. The main premise of this study is due to a concept of economic and social sustainability of museums, defined as the possession of sufficient resources to maintain the existence of an organization, and achieve their goals in the future, ensuring a certain flow of visitors. A great number of museums are characterized by a low number of visits; therefore, in order to become sustainable, museums should pay attention to audience and its internal diversity. In this way, a cultural site can plan tailored strategies to increase the number of visits and re-visits and to achieve community support. For this reason it is necessary to understand the cultural needs of visitors, acquiring appropriate monitoring tools, such as qualitative and quantitative ones. Generally, quantitative analyses are more reliable and complete, even if they require a considerable number of observations for the reliability of the results. Moreover, qualitative analysis provides more in depth information, even if their data do not allow us to make generalizations. The qualitative and quantitative methods for the detection of satisfaction are usually used separately, but their integration may bring significant added value in terms of the wealth of information. This study follows the analysis of the potential of the integration of qualitative and quantitative analysis techniques customized with respect to different types of targets. The results of the experimentation performed on ethnographic museums shows a consistency of the results obtained by the two different tools that increase the capacity information of survey instruments.

  10. 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.

    Globally, trade and industry has shifted its focus from the traditional service delivery approaches to various alternative practices to be more successful, cost efficient, customer orientated, flexible and innovative. This shift in focus has lead to organisations applying a customer centric approach in their business. In order to understand customer centricity, it is necessary to be familiar with the term customer service. Customer service is the offering of services to customers before, d...

  12. COORDINATION IN MULTILEVEL NETWORK-CENTRIC CONTROL SYSTEMS OF REGIONAL SECURITY: APPROACH AND FORMAL MODEL

    Directory of Open Access Journals (Sweden)

    A. V. Masloboev

    2015-01-01

    Full Text Available The paper deals with development of methods and tools for mathematical and computer modeling of the multilevel network-centric control systems of regional security. This research is carried out under development strategy implementation of the Arctic zone of the Russian Federation and national safeguarding for the period before 2020 in the Murmansk region territory. Creation of unified interdepartmental multilevel computer-aided system is proposed intended for decision-making information support and socio-economic security monitoring of the Arctic regions of Russia. The distinctive features of the investigated system class are openness, self-organization, decentralization of management functions and decision-making, weak hierarchy in the decision-making circuit and goal generation capability inside itself. Research techniques include functional-target approach, mathematical apparatus of multilevel hierarchical system theory and principles of network-centric control of distributed systems with pro-active components and variable structure. The work considers network-centric management local decisions coordination problem-solving within the multilevel distributed systems intended for information support of regional security. The coordination problem-solving approach and problem formalization in the multilevel network-centric control systems of regional security have been proposed based on developed multilevel recurrent hierarchical model of regional socio-economic system complex security. The model provides coordination of regional security indexes, optimized by the different elements of multilevel control systems, subject to decentralized decision-making. The model specificity consists in application of functional-target technology and mathematical apparatus of multilevel hierarchical system theory for coordination procedures implementation of the network-centric management local decisions.

    2016-12-01

    Full Text Available Aim/Purpose: The objective of this paper is to review the vast literature of user-centric in-formation science and inform about the emerging themes in information behaviour science. Background:\tThe paradigmatic shift from system-centric to user-centric approach facilitates research on the cognitive and individual information processing. Various information behaviour theories/models emerged. Methodology: Recent information behaviour theories and models are presented. Features, strengths and weaknesses of the models are discussed through the analysis of the information behaviour literature. Contribution: This paper sheds light onto the weaknesses in earlier information behaviour models and stresses (and advocates the need for research on social information behaviour. Findings: Prominent information behaviour models deal with individual information behaviour. People live in a social world and sort out most of their daily or work problems in groups. However, only seven papers discuss social information behaviour (Scopus search. Recommendations for Practitioners\t: ICT tools used for inter-organisational sharing should be redesigned for effective information-sharing during disaster/emergency times. Recommendation for Researchers: There are scarce sources on social side of the information behaviour, however, most of the work tasks are carried out in groups/teams. Impact on Society: In dynamic work contexts like disaster management and health care settings, collaborative information-sharing may result in decreasing the losses. Future Research: A fieldwork will be conducted in disaster management context investigating the inter-organisational information-sharing.

    OpenAIRE

    Senarath, Awanthika; Arachchilage, Nalin A. G.; Slay, Jill

    2017-01-01

    Privacy directly concerns the user as the data owner (data- subject) and hence privacy in systems should be implemented in a manner which concerns the user (user-centered). There are many concepts and guidelines that support development of privacy and embedding privacy into systems. However, none of them approaches privacy in a user- centered manner. Through this research we propose a framework that would enable developers and designers to grasp privacy in a user-centered manner and implement...

    Directory of Open Access Journals (Sweden)

    Gheorghe MINCULETE

    2013-01-01

    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.

  16. 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.

  17. A Cross-Layer User Centric Vertical Handover Decision Approach Based on MIH Local Triggers

    Science.gov (United States)

    Rehan, Maaz; Yousaf, Muhammad; Qayyum, Amir; Malik, Shahzad

    Vertical handover decision algorithm that is based on user preferences and coupled with Media Independent Handover (MIH) local triggers have not been explored much in the literature. We have developed a comprehensive cross-layer solution, called Vertical Handover Decision (VHOD) approach, which consists of three parts viz. mechanism for collecting and storing user preferences, Vertical Handover Decision (VHOD) algorithm and the MIH Function (MIHF). MIHF triggers the VHOD algorithm which operates on user preferences to issue handover commands to mobility management protocol. VHOD algorithm is an MIH User and therefore needs to subscribe events and configure thresholds for receiving triggers from MIHF. In this regard, we have performed experiments in WLAN to suggest thresholds for Link Going Down trigger. We have also critically evaluated the handover decision process, proposed Just-in-time interface activation technique, compared our proposed approach with prominent user centric approaches and analyzed our approach from different aspects.

    Modeling is used increasingly in healthcare to increase shared knowledge, to improve the processes, and to document the requirements of the solutions related to health information systems (HIS). There are numerous modeling approaches which aim to support these aims, but a careful assessment of their strengths, weaknesses and deficiencies is needed. In this paper, we compare three model-centric approaches in the context of HIS development: the Model-Driven Architecture, Business Process Modeling with BPMN and BPEL and the HL7 Development Framework. The comparison reveals that all these approaches are viable candidates for the development of HIS. However, they have distinct strengths and abstraction levels, they require local and project-specific adaptation and offer varying levels of automation. In addition, illustration of the solutions to the end users must be improved.

  19. User Centric Job Monitoring – a redesign and novel approach in the STAR experiment

    2014-01-01

    User Centric Monitoring (or UCM) has been a long awaited feature in STAR, whereas programs, workflows and system 'events' could be logged, broadcast and later analyzed. UCM allows to collect and filter available job monitoring information from various resources and present it to users in a user-centric view rather than an administrative-centric point of view. The first attempt and implementation of 'a' UCM approach was made in STAR 2004 using a log4cxx plug-in back-end and then further evolved with an attempt to push toward a scalable database back-end (2006) and finally using a Web-Service approach (2010, CSW4DB SBIR). The latest showed to be incomplete and not addressing the evolving needs of the experiment where streamlined messages for online (data acquisition) purposes as well as the continuous support for the data mining needs and event analysis need to coexists and unified in a seamless approach. The code also revealed to be hardly maintainable. This paper presents the next evolutionary step of the UCM toolkit, a redesign and redirection of our latest attempt acknowledging and integrating recent technologies and a simpler, maintainable and yet scalable manner. The extended version of the job logging package is built upon three-tier approach based on Task, Job and Event, and features a Web-Service based logging API, a responsive AJAX-powered user interface, and a database back-end relying on MongoDB, which is uniquely suited for STAR needs. In addition, we present details of integration of this logging package with the STAR offline and online software frameworks. Leveraging on the reported experience and work from the ATLAS and CMS experience on using the ESPER engine, we discuss and show how such approach has been implemented in STAR for meta-data event triggering stream processing and filtering. An ESPER based solution seems to fit well into the online data acquisition system where many systems are monitored.

    Despite occupying a cornerstone position in consumer research and innovation, product liking/disliking provides only partial insight into consumer behaviour. By adopting a consumer-centric perspective and drawing on additional factors that underpin food-related consumer behaviour, a more complete product understanding is gained. The present research showcases this approach in a study with New Zealand beer (incl. pilsner, lager and ale categories). Implementation of a multi-variate approach with 128 regular beer drinkers provided assessments pertaining to liking and sensory novelty/complexity, situational appropriateness of consumption, as well as attitudes/perceptions and emotional associations. The 9 samples grouped into two clusters, where 4 of the beers were similar in being perceived as having less complex flavours, being appropriate for many uses and evoking stronger emotional associations of "relaxed/calm." The 4 beers were perceived as "easy to drink", and were, on average, most liked. One of the samples in this cluster was lighter in alcohol (2.5% ABV), but not inferior to beers with 4-5% ABV. The 5 beers in the second cluster were, on average, less liked and were associated with more negative emotions, e.g. "unhappy, "jittery", and "tense". Additional insights were gained from segmentation which identified two groups of consumers, named 'Lager Lovers' and 'Ale Aficionados'. Beers 1-4 were positively perceived by 'Lager Lovers' but less so by 'Ale Aficionados', and vice versa. The study was conducted under central location test conditions compatible with testing protocols often used in product research. The study protocol can be amended to include few/many consumer-centric measures and extended to product testing where packaging, brand, and other extrinsic information is available to consumers.

  3. 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

    2012-01-01

    Rural electrification (RE) has gained prominence over the past two decades as an effective means for improving living conditions. This growth has largely been driven by socio-economic and political imperatives to improve rural livelihood and by technological innovation. Based on a content analysis of 232 scholarly articles, the literature is categorized into four focal lenses: technology, institutional, viability and user-centric. We find that the first two dominate the RE debate. The viability lens has been used less frequently, whilst the user-centric lens began to engage scholars as late as 2007. We provide an overview of the technological, institutional and viability lenses, and elaborate upon the user-centric lens in greater detail. For energy policy and practice, we combine the four lenses to develop a business model framework that policy makers, practitioners and investors could use to assess RE projects or to design future rural electrification strategies. - Highlights: ► Review of two decades of rural electrification research. ► Content analysis of 232 scholarly articles. ► Literature is categorized into four focal lenses: technology, institutional, viability and user-centric. ► We develop a business model framework for rural electrification strategies.

  6. 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.

    Full Text Available Supermarket retailers in India admist fierce competition and the only way out is through the attainment of competitive advantage. Strategy is the route to attain competitive advantage that could facilitate firms attain superior performance. The objective of this paper is to develop a conceptual framework on customer-centric retail strategy, to facilitate supermarket retailers in India attain competitive advantage. The paper draws heavily from existing literature on retail strategies and competitive advantage in order to ascertain the most effective customer-centric strategies. Adding strength to the research is the result derived from interviews of supermarket managers and customers; and also the results of pilot study .The work involves identification of constructs and research hypothesis for the proposed framework. The framework contributes to literature by emphasizing on not just effective customer-centric strategies but also, on specific performance outcomes that supermarket retailers could be enjoying riding on these strategies. A new dimension to attainment of competitive advantage and superior performance has definitely been recognized by this research effort. Supermarket retailers in India can be certain of attaining competitive advantage by riding on the proposed strategies.

  8. [A non-classical approach to medical practices: Michel Foucault and Actor-Network Theory].

    Bińczyk, E

    2001-01-01

    The text presents an analysis of medical practices stemming from two sources: Michel Foucault's conception and the research of Annemarie Mol and John Law, representatives of a trend known as Actor-Network Theory. Both approaches reveal significant theoretical kinship: they can be successfully consigned to the framework of non-classical sociology of science. I initially refer to the cited conceptions as a version of non-classical sociology of medicine. The identity of non-classical sociology of medicine hinges on the fact that it undermines the possibility of objective definitions of disease, health and body. These are rather approached as variable social and historical phenomena, co-constituted by medical practices. To both Foucault and Mol the main object of interest was not medicine as such, but rather the network of medical practices. Mol and Law sketch a new theoretical perspective for the analysis of medical practices. They attempt to go beyond the dichotomous scheme of thinking about the human body as an object of medical research and the subject of private experience. Research on patients suffering blood-sugar deficiency provide the empirical background for the thesis of Actor-Network Theory representatives. Michel Foucault's conceptions are extremely critical of medical practices. The French researcher describes the processes of 'medicalising' Western society as the emergence of a new type of power. He attempts to sensitise the reader to the ethical dimension of the processes of medicalising society.

  9. Let there be light: A multi-actor approach to alleviating energy poverty in Asia

    International Nuclear Information System (INIS)

    Spagnoletti, Belinda; O’Callaghan, Terry

    2013-01-01

    Energy poverty is the primary energy security issue impacting almost 800 million people, particularly women and children, in the developing countries of Asia. Current trends indicate that should there be no change to existing policies, and the governance systems and institutions underpinning them, the absolute number of energy poor will barely shift. Most significantly, addressing energy poverty is critical to absolute poverty reduction, enhanced gender equality and political stability in the Asian region. We offer a solution to progress the energy poverty alleviation effort focused on encouraging sustainable, development-centred investment. This will involve multi-actor partnerships between developed and developing country governments, investors, and multilateral institutions. We propose that there may be spill over effects for investing firms, in the form of strengthened corporate reputation. Consequently, energy poverty alleviation efforts can create new opportunities for commerce, multilateral institutions, NGOs, and developing and developed countries. It is envisaged that the multi-actor approach put forward by this paper will facilitate the partnerships, programs and provisions needed to alleviate energy poverty in Asia. However, critical to the success of this collaborative approach is a genuine shift in sentiment from the key stakeholders involved in the effort

  10. The Patient's Voice in Pharmacovigilance: Pragmatic Approaches to Building a Patient-Centric Drug Safety Organization.

    Smith, Meredith Y; Benattia, Isma

    2016-09-01

    Patient-centeredness has become an acknowledged hallmark of not only high-quality health care but also high-quality drug development. Biopharmaceutical companies are actively seeking to be more patient-centric in drug research and development by involving patients in identifying target disease conditions, participating in the design of, and recruitment for, clinical trials, and disseminating study results. Drug safety departments within the biopharmaceutical industry are at a similar inflection point. Rising rates of per capita prescription drug use underscore the importance of having robust pharmacovigilance systems in place to detect and assess adverse drug reactions (ADRs). At the same time, the practice of pharmacovigilance is being transformed by a host of recent regulatory guidances and related initiatives which emphasize the importance of the patient's perspective in drug safety. Collectively, these initiatives impact the full range of activities that fall within the remit of pharmacovigilance, including ADR reporting, signal detection and evaluation, risk management, medication error assessment, benefit-risk assessment and risk communication. Examples include the fact that manufacturing authorization holders are now expected to monitor all digital sources under their control for potential reports of ADRs, and the emergence of new methods for collecting, analysing and reporting patient-generated ADR reports for signal detection and evaluation purposes. A drug safety department's ability to transition successfully into a more patient-centric organization will depend on three defining attributes: (1) a patient-centered culture; (2) deployment of a framework to guide patient engagement activities; and (3) demonstrated proficiency in patient-centered competencies, including patient engagement, risk communication and patient preference assessment. Whether, and to what extent, drug safety departments embrace the new patient-centric imperative, and the methods and

    Full Text Available In the State of Israel, advanced legislation for the management of scarce water resources, including legislation to prevent water pollution, were put in place in the early stages of the State’s formation. Despite that, on-going uncontrolled pollution has deteriorated the quality of water sources for decades, with the main source of pollution being untreated or partially treated domestic wastewater. This has been mainly the result of lack of enforcement of the existing laws. During the 1990s and onwards, a shift to forceful enforcement has been observed and wastewater treatment substantially improved. The paper analyzes the implementation processes of the pollution control legislations (the lack-of and the shift to forceful enforcement based on an actor-centered approach, using the contextual interaction theory.

    Recently, reinforcement learning methods have drawn significant interests in the area of artificial intelligence, and have been successfully applied to various decision-making problems. In this paper, we study the applicability of the NAC (natural actor-critic) approach, a state-of-the-art reinforcement learning method, to the drug scheduling of cancer chemotherapy for an ODE (ordinary differential equation)-based tumor growth model. ODE-based cancer dynamics modeling is an active research area, and many different mathematical models have been proposed. Among these, we use the model proposed by de Pillis and Radunskaya (2003), which considers the growth of tumor cells and their interaction with normal cells and immune cells. The NAC approach is applied to this ODE model with the goal of minimizing the tumor cell population and the drug amount while maintaining the adequate population levels of normal cells and immune cells. In the framework of the NAC approach, the drug dose is regarded as the control input, and the reward signal is defined as a function of the control input and the cell populations of tumor cells, normal cells, and immune cells. According to the control policy found by the NAC approach, effective drug scheduling in cancer chemotherapy for the considered scenarios has turned out to be close to the strategy of continuing drug injection from the beginning until an appropriate time. Also, simulation results showed that the NAC approach can yield better performance than conventional pulsed chemotherapy. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    During the last years, a variety of concepts for service integration and corresponding systems have gained momentum. On the one hand, they aim for the interworking and integration of classical telecommunications and data communications services. On the other hand, they are focusing on universal service access from a variety of end user systems. Looking at humans' communication behavior and communication space, it is obvious that human beings interact frequently in a set of contexts in their environment (communication space). Following this view, we want to build communication systems on the analysis of the individual communication spaces. The results are communication systems adapted to the specific demands of each individual. The authors introduce I-centric Communication Systems, an approach to design communication systems which adapt to the individual communication space and individual environment and situation. In this context "I" means I, or individual, "Centric" means adaptable to I requirements and a ce...

    The extent of universal health coverage in terms of financial protection is worrisome in Iran. There are challenges in health policies to guarantee financial accessibility to health services, especially for poor people. Various institutions offer support to ensure that the poor have financial access to health services. The aim of this study is to investigate the relationship network among the institutions active in this field. This study is a policy document analysis. It evaluates the country's legal documents in the field of financial support to the poor for healthcare after the Islamic Revolution in Iran. The researchers looked for the documents on the related websites and referred to the related organizations. The social network analysis approach was chosen for the analysis of the documents. Block-modelling and multi-dimensional scaling (MDS) was used to determine the network structures. The UCINET software was employed to analyse the data. Most the main actors of this network are chosen from the government budget. There is no legal communication and cooperation among some of the actors because of their improper position in the network. Seven blocks have been clustered by CONCOR in terms of the actor's degree of similarity. The social distance among the actors of the seven blocks is very short. Power distribution in the field of financial support to the poor has a fragmented structure; however, it is mainly run by a dominant block consisting of The Supreme Council of Welfare and Social Security, Health Insurance Organization, and the Ministry of Health and Medical Education. The financial support for the poor network involves multiple actors. This variety has created a series of confusions in terms of the type, level, and scope of responsibilities among the actors. The weak presence legislative and regulatory institutions and also non-governmental institutions are the main weak points of this network. Copyright © 2017 Elsevier Ltd. All rights reserved.

  19. An Extended Petri-Net Based Approach for Supply Chain Process Enactment in Resource-Centric Web Service Environment

    Enacting a supply-chain process involves variant partners and different IT systems. REST receives increasing attention for distributed systems with loosely coupled resources. Nevertheless, resource model incompatibilities and conflicts prevent effective process modeling and deployment in resource-centric Web service environment. In this paper, a Petri-net based framework for supply-chain process integration is proposed. A resource meta-model is constructed to represent the basic information of resources. Then based on resource meta-model, XML schemas and documents are derived, which represent resources and their states in Petri-net. Thereafter, XML-net, a high level Petri-net, is employed for modeling control and data flow of process. From process model in XML-net, RESTful services and choreography descriptions are deduced. Therefore, unified resource representation and RESTful services description are proposed for cross-system integration in a more effective way. A case study is given to illustrate the approach and the desirable features of the approach are discussed.

    Innovation and diffusion of renewable energy technologies play a major role in mitigation of climate change. In Sweden replacing electric and oil heating systems with innovative heating systems such as district heating, heat pumps and wood pellet boilers in detached homes is a significant mitigation option. Using an adopter-centric approach, we analyzed the influence of investment subsidy on conversion of resistance heaters and oil boilers, and the variation in diffusion pattern of district heating, heat pumps and pellet boilers in Swedish detached homes. Results from questionnaire surveys of 1500 randomly selected homeowners in September 2004 and January 2007 showed that more than 80% of the respondents did not intend to install a new heating system. Hence, about 37% of the homeowners still have electric and oil heating systems. The government investment subsidy was important for conversion from a resistance heater, but not from an oil boiler. This is because homeowners currently replacing their oil boilers are the laggards, while those replacing resistance heaters are the 'early adopters'. Economic aspects and functional reliability were the most important factors for the homeowners when considering a new heating system. There is a variation in the perceived advantages associated with each of the innovative heating systems and therefore, the diffusion patterns of such systems vary. Installers and interpersonal sources were the most important communication channels for information on heating systems

    Integration of heterogeneous and distributed systems is a challenging task, because they might be running on different platforms and written with different implementation languages by multiple organizations. Data-centricity and event-driven architecture (EDA) are concepts that help to implement versatile and well-scaling distributed systems. This paper focuses on the implementation of inter-subsystem communication in a prototype distributed remote handling control system developed at Divertor Test Platform 2 (DTP2). The control system consists of a variety of heterogeneous subsystems, including a client–server web application and hard real-time controllers. A standardized middleware solution (Data Distribution Services (DDS)) that supports a data-centric EDA approach is used to integrate the system. One of the greatest challenges in integrating a system with a data-centric EDA approach is in defining the global data space model. The selected middleware is currently only used for non-deterministic communication. For future application, we evaluated the performance of point-to-point communication with and without the presence of additional network load to ensure applicability to real-time systems. We found that, under certain limitations, the middleware can be used for soft real-time communication. Hard real-time use will require more validation with a more suitable environment.

  8. A dialogue-centric approach to environmental-remediation decision-making - 59115

    Boucher, Laurel; Clark, James F.

    2012-01-01

    This paper outlines a multi-step approach to streamline and enhance the decision-making process that guides environmental remediation. The inability of the responsible party and the various stakeholders to reach agreement on the remediation plan can delay the remediation, result in financial penalties, and lead to the development of an adversarial stance that inhibits the ability of the parties to work together in a creative and constructive manner. The approach presented by the authors is designed to expand dialogue in a way that moves it beyond technical or fiscal matters by addressing what the authors describe as the 'hidden barriers' to productive dialogue. These 'hidden barriers' include: self-interests, the perception as to how people are being treated, a lack of clarity or poor management of responsibilities and accountabilities, unclear or convoluted communication protocols, and an underlying tone of conflict and cynicism. A key element of the multi-step approach outlined in this paper is the process of uncovering these 'hidden barriers' and addressing them in a way that turns discourse into collaboration. The paper describes a model the authors have used to streamline and enhance the process of creating sustainable agreements both for the U.S. Department of Energy's Office of Environmental Management as well as the U.S. Department of Defense for a variety of environmental remediation projects. The results of this approach include the acceleration of an environmental clean-up from a projected 19 years to 11 years, the development of innovative technical strategies, the reduction of a major backlog of environmental proposals requiring review and comment, and the distinction accorded one group of being recognized as a model of effective partnering. The approach described has widespread implications not only because its use can be expanded to include a multitude of decision-making applications but also because of the impact it creates by expanding both the

    High performance computing environments are often used for a wide variety of workloads ranging from simulation, data transformation and analysis, and complex workflows to name just a few. These systems may process data at various security levels but in so doing are often enclaved at the highest security posture. This approach places significant restrictions on the users of the system even when processing data at a lower security level and exposes data at higher levels of confidentiality to a much broader population than otherwise necessary. The traditional approach of isolation, while effective in establishing security enclaves poses significant challenges for the use of shared infrastructure in HPC environments. This report details current state-of-the-art in virtualization, reconfigurable network enclaving via Software Defined Networking (SDN), and storage architectures and bridging techniques for creating secure enclaves in HPC environments.

  10. Simplifying the parallelization of scientific codes by a function-centric approach in Python

    2010-01-01

    The purpose of this paper is to show how existing scientific software can be parallelized using a separate thin layer of Python code where all parallelization-specific tasks are implemented. We provide specific examples of such a Python code layer, which can act as templates for parallelizing a wide set of serial scientific codes. The use of Python for parallelization is motivated by the fact that the language is well suited for reusing existing serial codes programmed in other languages. The extreme flexibility of Python with regard to handling functions makes it very easy to wrap up decomposed computational tasks of a serial scientific application as Python functions. Many parallelization-specific components can be implemented as generic Python functions, which may take as input those wrapped functions that perform concrete computational tasks. The overall programming effort needed by this parallelization approach is limited, and the resulting parallel Python scripts have a compact and clean structure. The usefulness of the parallelization approach is exemplified by three different classes of application in natural and social sciences.

  11. Opening the black box of quality improvement collaboratives: an Actor-Network theory approach

    2010-09-01

    Full Text Available Abstract Background Quality improvement collaboratives are often labeled as black boxes because effect studies usually do not describe exactly how the results were obtained. In this article we propose a way of opening such a black box, by taking up a dynamic perspective based on Actor-Network Theory. We thereby analyze how the problematisation process and the measurement practices are constructed. Findings from this analysis may have consequences for future evaluation studies of collaboratives. Methods In an ethnographic design we probed two projects within a larger quality improvement collaborative on long term mental health care and care for the intellectually disabled. Ethnographic observations were made at nine national conferences. Furthermore we conducted six case studies involving participating teams. Additionally, we interviewed the two program leaders of the overall projects. Results In one project the problematisation seemed to undergo a shift of focus away from the one suggested by the project leaders. In the other we observed multiple roles of the measurement instrument used. The instrument did not only measure effects of the improvement actions but also changed these actions and affected the actors involved. Conclusions Effectiveness statistics ideally should be complemented with an analysis of the construction of the collaborative and the improvement practices. Effect studies of collaboratives could benefit from a mixed methods research design that combines quantitative and qualitative methods.

    To better understand and mitigate the impacts of humans on the water cycle, the importance of studying the co-evolution of coupled human-water systems has been recognized. Because of its unique system dynamics, the Murrumbidgee river basin (part of the larger Murray-Darlin basin, Australia) is one of the main study areas in the emerging field of socio-hydrology. In recent years, various historical and modeling studies have contributed to gaining a better understanding of this system's behavior. Kandasamy et al. (2014) performed a historical study on the development of this human-water coupled system. They identified four eras, providing a historical context of the observed "pendulum" swing between first an exclusive focus on agricultural development, followed by increasing environmental awareness, subsequent efforts to mitigate, and finally to restore environmental health. A modeling effort by Van Emmerik et al. (2014) focused on reconstructing hydrological, economical, and societal dynamics and their feedbacks. A measure of changing societal values was included by introducing environmental awareness as an endogenously modeled variable, which resulted in capturing the co-evolution between economic development and environmental health. Later work by Elshafei et al. (2015) modeled and analyzed the two-way feedbacks of land use management and land degradation in two other Australian coupled systems. A composite variable, community sensitivity, was used to measure changing community sentiment, such that the model was capable of isolating the two-way feedbacks in the coupled system. As socio-hydrology adopts a holistic approach, it is often required to introduce (hydrologically) unconventional variables, such as environmental awareness or community sensitivity. It is the subject of ongoing debate how such variables can be validated, as there is no standardized data set available from hydrological or statistical agencies. Recent research (Wei et al. 2017) has provided

  13. Value centric approaches to the design, operations and maintenance of wind turbines

    Science.gov (United States)

    Khadabadi, Madhur Aravind

    Wind turbine maintenance is emerging as an unexpectedly high component of turbine operating cost, and there is an increasing interest in managing this cost. This thesis presents an alternative view of maintenance as a value-driver, and develops an optimization algorithm to evaluate the value delivered by different maintenance techniques. I view maintenance as an operation that moves the turbine to an improved state in which it can generate more power and, thus, earn more revenue. To implement this approach, I model the stochastic deterioration of the turbine in two dimensions: the deterioration rate, and the extent of deterioration, and then use maintenance to improve the state of the turbine. The value of the turbine is the difference between the revenue from to the power generation and the costs incurred in operation and maintenance. With a focus on blade deterioration, I evaluate the value delivered by implementing two different maintenance schemes, predictive maintenance and scheduled maintenance. An example of predictive maintenance technique is the use of Condition Monitoring Systems to precisely detect deterioration. I model Condition Monitoring System (CMS) of different degrees of fidelity, where a higher fidelity CMS would allow the blade state to be determined with a higher precision. The same model is then applied for the scheduled maintenance technique. The improved state information obtained from these techniques is then used to derive an optimal maintenance strategy. The difference between the value of the turbine with and without the inspection type can be interpreted as the value of the inspection. The results indicate that a higher fidelity (and more expensive) inspection method does not necessarily yield the highest value, and, that there is an optimal level of fidelity that results in maximum value. The results also aim to inform the operator of the impact of regional parameters such as wind speed, variance and maintenance costs to the optimal

    The downsizing of the Department of Defense (DoD) and the associated reduction in budgets has re-emphasized the need for commonality, reuse, and standards with respect to the way DoD does business. DoD has implemented significant changes in how it buys weapon systems. The new emphasis is on concurrent engineering with Integrated Product and Process Development and collaboration with Integrated Product Teams. The new DoD vision includes Simulation Based Acquisition (SBA), a process supported by robust, collaborative use of simulation technology that is integrated across acquisition phases and programs. This paper discusses the Air Force Research Laboratory's efforts to use Modeling and Simulation (M&S) resources within a Collaborative Enterprise Environment to support SBA and other Collaborative Enterprise and Virtual Prototyping (CEVP) applications. The paper will discuss four technology areas: (1) a Processing Ontology that defines a hierarchically nested set of collaboration contexts needed to organize and support multi-disciplinary collaboration using M&S, (2) a partial taxonomy of intelligent agents needed to manage different M&S resource contributions to advancing the state of product development, (3) an agent- based process for interfacing disparate M&S resources into a CEVP framework, and (4) a Model-View-Control based approach to defining `a new way of doing business' for users of CEVP frameworks/systems.

    Full Text Available The objective of this paper was to show the historical perspective of the „long centric" occlusal concept and its importance in the modern dentistry, especially from the gnathological aspect. The „long centric" concept represents therapeutic modality used in modern dentistry and occlusal adjustment in all patients showing differences in strong and weak closure of the lower jaw starting from the position of physiological rest/long centric" concept is applied only for anterior teeth and occlusal movements from rather than toward the center. Whenever the „long centric" parameters are not adequate, occlusal disturbance, resulting from the „wedge" effect during the initial closure of the lower jaw, is present. Different degrees of abrasion or hypermobility of the teeth are often the result of the above-mentioned occlusal disturbances and can potentially trigger bruxism and malfunction. Modus procedendi should be the regular approach of every dentist to any occlusion, because only the built-in „long centric" efficiently contributes to the occlusal stability of the anterior portion of the dentition. All occlusions should be routinely tested regarding their need for „long centric", especially when the extensive therapeutic interventions (conservative, prosthetics of the occlusal complex are required.

    Full Text Available Abstract In the area of Administration, especially in the Organizational Studies (OS, the Actor-Network Theory (ANT has been regarded as part of a movement that aims to leave the functional emphasis of organization and pursue the study of process and practices of organizing - the processual approach to organizations. However, criticism to the ANT has led some authors to seek to overcome them through analytical twists concerning certain concepts. One of these "twists" involved the concept of translation and the inclusion of the concept of enactment . This article discusses both notions with the aid of two studies developed having these concepts as a basis, in order to indicate that the choice of enactment brings along a processual view different from that observed in translation. The concept of translation addresses the predominant and it emphasizes understanding how networks of relationships and objects become "stable"; in turn, enact works with multiplicity and fluidity, where the process takes precedence over things. Although the proposed term enactment does not seek to directly face all criticism, it contributes so that ANT does not take a neutral or mechanical view in its analyses and descriptions. Enactment has the view of organization as a result and product of continuous process and it allows understanding that this is not just working or not (success or failure, but it concerns the "production" of multiple realities when we conduct research in Administration having the processual approach to organizations as a basis.

    Full Text Available This article explores the stages of integration of immigrant associations in Spain according to stock of social capital, specifically, given the relationships established with actors in the environment, and consequently this role is derived for each type of counterpart. The data are drawn from a representative sample consisting of 225 immigrant associations around the country. The results suggest that immigrant associations play cohesive and specific roles with their peers, even achieve certain asymmetries in their favor with certain actors in the host society. On the other hand, native actors host society are distributed in a continuum ranging from the development of specific roles to other multiple, and even contradictory, which, as a whole, ends up drawing a map of complex and diverse opportunities for integration of associations.

  1. A novel approach to locomotion learning: Actor-Critic architecture using central pattern generators and dynamic motor primitives.

    Li, Cai; Lowe, Robert; Ziemke, Tom

    2014-01-01

    In this article, we propose an architecture of a bio-inspired controller that addresses the problem of learning different locomotion gaits for different robot morphologies. The modeling objective is split into two: baseline motion modeling and dynamics adaptation. Baseline motion modeling aims to achieve fundamental functions of a certain type of locomotion and dynamics adaptation provides a "reshaping" function for adapting the baseline motion to desired motion. Based on this assumption, a three-layer architecture is developed using central pattern generators (CPGs, a bio-inspired locomotor center for the baseline motion) and dynamic motor primitives (DMPs, a model with universal "reshaping" functions). In this article, we use this architecture with the actor-critic algorithms for finding a good "reshaping" function. In order to demonstrate the learning power of the actor-critic based architecture, we tested it on two experiments: (1) learning to crawl on a humanoid and, (2) learning to gallop on a puppy robot. Two types of actor-critic algorithms (policy search and policy gradient) are compared in order to evaluate the advantages and disadvantages of different actor-critic based learning algorithms for different morphologies. Finally, based on the analysis of the experimental results, a generic view/architecture for locomotion learning is discussed in the conclusion.

    2017-10-01

    Previous studies found gender differences in relationship satisfaction and sexuality. We tested gender differences in associations between attachment, a lasting relationship determinant, and two outcomes, relationship and sexual satisfaction. This study improves on earlier research by examining these associations in one Actor-Partner-Interdependence-Model, making direct statistical testing between outcomes possible. Furthermore, a community and a distressed sample (N = 113 heterosexual couples each) were included to attempt replication across samples and to examine clinical implications. In both genders, actor attachment avoidance negatively affected relationship satisfaction and (with one exception) sexual satisfaction. Also in both genders, partner attachment avoidance negatively affected sexual satisfaction. However, whereas partner attachment avoidance influenced female relationship satisfaction, it did not affect male relationship satisfaction. The findings replicated across samples. Clinical implications are discussed. © 2017 American Association for Marriage and Family Therapy.

  5. Following the moving and changing attachments and assemblages of 'addiction': Applying the actor network approach to autobiographies.

    Törrönen, Jukka; Tigerstedt, Christoffer

    2018-04-01

    The article applies actor network theory (ANT) to autobiographical data on alcohol dependence to explore what ANT can offer to the analysis of 'addiction stories'. By defining 'addiction' as a relational achievement, as the effect of elements acting together as a configuration of human and non-human actors, the article demonstrates how the moving and changing attachments of addiction can be dynamically analyzed with concepts of 'assemblage', 'mediator', 'tendency', 'translation', 'trajectory', 'immutable mobile', 'fluid' and 'bush fire'. The article shows how the reduction of alcohol dependence simply to genetic factors, neurobiological causes, personality disorders and self-medication constitutes an inadequate explanation. As 'meta theories', they illuminate addiction one-sidedly. Instead, as ANT pays attention to multiple heterogeneous mediators, it specifies in what way the causes identified in 'meta theories' may together with other actors participate in addiction assemblages. When following the development of addiction assemblages, we focus on situational sequences of action, in which human and non-human elements are linked to each other, and we trace how the relational shape of addiction changes from one sequence to another as a transforming assemblage of heterogeneous attachments that either maintain healthy subjectivities or destabilize them. The more attachments assemblages of addiction are able to make that are flexible and durable from one event to another, the stronger also the addiction-based subjectivities. Similarly, the fewer attachments that assemblages of addiction are able to keep in their various translations, the weaker the addiction-based subjectivities also become. An ANT-inspired analysis has a number of implications for the prevention and treatment of addiction: it suggests that in the prevention and treatment of addiction, the aim should hardly be to get rid of dependencies. Rather, the ambition should be the identification of attachments

  7. 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.

    Full Text Available The gathering pace of IT innovation has, or ought to have had notable methodological repercussions for the social-science community (and beyond. Where yesterday the researcher could unhurriedly unlock the social-scientific significance of a chosen medium, secure in the knowledge that his or her work would have bearing for many years, by now there is every reason to confront a fear that the prodded IT implementation may in fact be gone or at least heavily altered by the time such comprehensive research is concluded. This paper will propose a complementing systematic "interface-centric" research model capable of interconnecting a non-finite variety of IT implementations and social science studies in a coherent way. The paper also outlines how users "downstream", whether political actors or technology operators can use the proposed framework to more easily approach and weight academic input when evaluating complex IT effects.

  10. Linking the actors and policies throughout the disaster management cycle by "Agreement on Objectives" – a new output-oriented management approach

    2012-04-01

    Full Text Available Current management of disaster risks is often fragmented due to a lack of coordination between involved actors, i.e. civil protection and spatial planning – a phenomenon which is known as the "problem of interplay". This paper presents an output-oriented risk management approach ("parametric governance". Here, the modality of the achievement of objectives remains in the hands of the given addressees. This implies a shift from a top-down to a more collaborative, process-oriented form of decision-making. The approach has been successfully applied in two hazard cases and three administrative contexts: (a the City of Dortmund (Germany facing flash floods, (b East Attica region (Greece facing forest fires, and (c Lazio Region (Italy also facing forest fires. As proved by the applications of the concept, a dialogue among experts, stakeholders, and decision-makers is indispensable in order to guarantee inclusion of all diverse and competing values, opinions, and claims. Moreover, a structured communication path is needed to meet the requirements of a risk governance process. Finally, a win-win-situation among the involved actors has to be created to reach an agreement on common goals and actions to achieve them in due time.

  11. 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.

    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.

  17. EU-Centric Governance in Sport? The Slovenian Experience with the White Paper Process

    Directory of Open Access Journals (Sweden)

    Simona Kustec Lipicer

    2007-12-01

    Full Text Available A synthesis of existing academic, expert and everyday practical political literature demonstrates that we can trace many different approaches to the phenomena of governance. Based on the political sciences, particularly policy literature, the governance concept is most frequently connected with an analysis of the relations between actors or institutions of the state and society at different political levels. Use of the governance concept is also becoming increasingly popular when discussing sports issues, especially when the multi-level or global sport perspective is in question. This article aims to confront the national perspectives and understandings of, as well as attempts at, sports governance, in relation to multi-level ones. This refers specifically the EU, because over the last few years, not only have states expanded their traditional concerns with health and social security to encompass leisure and cultural life, including sport, but the EU has also implemented different activities concerning sport issues. This particularly emphasises the extent and importance of the relations that key national policy actors have established with themselves and especially towards supra-national (EU actors in the processes of creating common EU sports policy directions as part of preparing the White Paper on Sport (2007. It does this by analysing the available official documents, records and statistics relating to the issue, as well as interviews conducted in spring 2007 with representatives of the state and sports-governing bodies in Slovenia. The conclusions of the analysis indicate a predominantly EU-centric type of multi-level governance approach and make some observations about the EU’s future development and how this could impact the development of (subnational sports policy.

  18. Financial stress, parent functioning and adolescent problem behavior: an actor-partner interdependence approach to family stress processes in low-, middle-, and high-income families.

    The family stress model proposes that financial stress experienced by parents is associated with problem behavior in adolescents. The present study applied an actor-partner interdependence approach to the family stress model and focused on low-, middle-, and high-income families to broaden our understanding of the pathways by which the financial stress of mothers and fathers are related to adolescent outcomes. The study uses dyadic data (N = 798 heterosexual couples) from the Relationship between Mothers, Fathers and Children study in which two-parent families with an adolescent between 11 and 17 years of age participated. Path-analytic results indicated that in each of the families the association between parents' financial stress and problem behavior in adolescents is mediated through parents' depressive symptoms, interparental conflict, and positive parenting. Family stress processes also appear to operate in different ways for low-, middle-, and high-income families. In addition to a higher absolute level of financial stress in low-income families, financial stress experienced by mothers and fathers in these families had significant direct and indirect effects on problem behavior in adolescents, while in middle- and high-income families only significant indirect effects were found. The financial stress of a low-income mother also had a more detrimental impact on her level of depressive feelings than it had on mothers in middle-income families. Furthermore, the study revealed gender differences in the pathways of mothers and fathers. Implications for research, clinical practice, and policy are also discussed.

    International Nuclear Information System (INIS)

    Nicquevert, B.

    2012-01-01

    In large projects such as particle accelerators or detectors, interfaces and boundaries reveal themselves to be both critical and underestimated. The technical manager, an actor among others, finds himself placed at network nodes where he must set up exchanges spaces in order to generate collaborative behaviours. Starting with case studies from the field of CERN, the thesis follows three principles based on the dia-logical, the hologramic and the self-eco-organization principles, as expanded in the writings on complexity. It puts forward an original methodological matrix construction leading to a transactional model of the interface actor. The collaborative exchanges spaces builds itself as a place for the dynamic transformation of the interface actor into a boundary actor. Intermediate objects, created during the design / integration process, are simultaneously transformed into boundary objects. They are instrumental in the realization of the product: this takes place in the framework of the project which has been determined through a recursive process. The interest generated by such a global and combined approach of this dynamic process leads to the proposal of a 'hyper-compass', with the aim of providing the means for the technical manager to orient his 'acting ↔ thinking'.

  2. SDN Based User-Centric Framework for Heterogeneous Wireless Networks

    2016-01-01

    Full Text Available Due to the rapid growth of mobile data traffic, more and more basestations and access points (APs have been densely deployed to provide users with ubiquitous network access, which make current wireless network a complex heterogeneous network (HetNet. However, traditional wireless networks are designed with network-centric approaches where different networks have different quality of service (QoS strategies and cannot easily cooperate with each other to serve network users. Massive network infrastructures could not assure users perceived network and service quality, which is an indisputable fact. To address this issue, we design a new framework for heterogeneous wireless networks with the principle of user-centricity, refactoring the network from users’ perspective to suffice their requirements and preferences. Different from network-centric approaches, the proposed framework takes advantage of Software Defined Networking (SDN and virtualization technology, which will bring better perceived services quality for wireless network users. In the proposed user-centric framework, control plane and data plane are decoupled to manage the HetNets in a flexible and coadjutant way, and resource virtualization technology is introduced to abstract physical resources of HetNets into unified virtualized resources. Hence, ubiquitous and undifferentiated network connectivity and QoE (quality of experience driven fine-grained resource management could be achieved for wireless network users.

    Large scale graph processing is a major research area for Big Data exploration. Vertex centric programming models like Pregel are gaining traction due to their simple abstraction that allows for scalable execution on distributed systems naturally. However, there are limitations to this approach which cause vertex centric algorithms to under-perform due to poor compute to communication overhead ratio and slow convergence of iterative superstep. In this paper we introduce GoFFish a scalable sub-graph centric framework co-designed with a distributed persistent graph storage for large scale graph analytics on commodity clusters. We introduce a sub-graph centric programming abstraction that combines the scalability of a vertex centric approach with the flexibility of shared memory sub-graph computation. We map Connected Components, SSSP and PageRank algorithms to this model to illustrate its flexibility. Further, we empirically analyze GoFFish using several real world graphs and demonstrate its significant performance improvement, orders of magnitude in some cases, compared to Apache Giraph, the leading open source vertex centric implementation.

  4. Manage customer-centric innovation--systematically.

    Selden, Larry; MacMillan, Ian C

    2006-04-01

    No matter how hard companies try, their approaches to innovation often don't grow the top line in the sustained, profitable way investors expect. For many companies, there's a huge difference between what's in their business plans and the market's expectations for growth (as reflected in firms' share prices, market capitalizations, and P/E ratios). This growth gap springs from the fact that companies are pouring money into their insular R&D labs instead of working to understand what the customer wants and using that understanding to drive innovation. As a result, even companies that spend the most on R&D remain starved for both customer innovation and market-capitalization growth. In this article, the authors spell out a systematic approach to innovation that continuously fuels sustained, profitable growth. They call this approach customer-centric innovation, or CCI. At the heart of CCI is a rigorous customer R&D process that helps companies to continually improve their understanding of who their customers are and what they need. By so doing, they consistently create or improve their customer value proposition. Customer R&D also focuses on better ways of communicating value propositions and delivering the complete experience to real customers. Since so much of the learning about customers and so much of the experimentation with different segmentations, value propositions, and delivery mechanisms involve the people who regularly deal with customers, it is absolutely essential for frontline employees to be at the center of the CCI process. Simply put, customer R&D propels the innovation effort away from headquarters and the traditional R&D lab out to those closest to the customer. Using the example of the luggage manufacturer Tumi, the authors provide a step-by-step approach for achieving true customer-centric innovation.

    Full Text Available The ubiquity of computing devices has led to an increased need to ensure not only that the applications deployed on them are correct with respect to their specifications, but also that the devices are used in an appropriate manner, especially in situations where the device is provided by a party other than the actual user. Much work which has been done on runtime verification for mobile devices and operating systems is mostly application-centric, resulting in global, device-centric properties (e.g. the user may not send more than 100 messages per day across all applications being difficult or impossible to verify. In this paper we present a device-centric approach to runtime verify the device behaviour against a device policy with the different applications acting as independent components contributing to the overall behaviour of the device. We also present an implementation for Android devices, and evaluate it on a number of device-centric policies, reporting the empirical results obtained.

    Digital fabrication—including additive manufacturing (AM), rapid prototyping and 3D printing—has the potential to revolutionize the way in which products are produced and delivered to the customer. Therefore, it challenges companies to reinvent their business model—describing the logic of creating...... and capturing value. In this paper, we explore the implications that AM technologies have for manufacturing systems in the new business models that they enable. In particular, we consider how a consumer goods manufacturer can organize the operations of a more open business model when moving from a manufacturer......-centric to a consumer-centric value logic. A major shift includes a move from centralized to decentralized supply chains, where consumer goods manufacturers can implement a “hybrid” approach with a focus on localization and accessibility or develop a fully personalized model where the consumer effectively takes over...

    Science.gov (United States)

    Fernandes, Kevin

    This thesis is oriented toward developers, owners, operators and investors of renewable energy projects. With increasing demand of renewables, our energy dependence comes down to reducing costs associated with this sector so as to compete with the existing sources. One way of valuing investment potential is to determine and then compare the overall value derived by investing in a particular project. Several engineering and financial levers, one of which is operation and maintenance, affect this value. This thesis provides a useful visual aid to owners and operators by which they can operate and maintain their wind farm so as to achieve maximum value throughout its lifetime. All the necessary components that go into developing a business model of a wind farm project will be discussed. Finally, this tool is valid within the assumptions that are explicitly stated. Real world data and trends are used to provide a practical approach to the optimization.

  20. 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

    Invasive annual weeds negatively impact ecosystem services and pose a major conservation threat on semiarid rangelands throughout the western United States. Rehabilitation of these rangelands is challenging due to interannual climate and subseasonal weather variability that impacts seed germination, seedling survival and establishment, annual weed dynamics, wildfire frequency, and soil stability. Rehabilitation and restoration outcomes could be improved by adopting a weather-centric approach that uses the full spectrum of available site-specific weather information from historical observations, seasonal climate forecasts, and climate-change projections. Climate data can be used retrospectively to interpret success or failure of past seedings by describing seasonal and longer-term patterns of environmental variability subsequent to planting. A more detailed evaluation of weather impacts on site conditions may yield more flexible adaptive-management strategies for rangeland restoration and rehabilitation, as well as provide estimates of transition probabilities between desirable and undesirable vegetation states. Skillful seasonal climate forecasts could greatly improve the cost efficiency of management treatments by limiting revegetation activities to time periods where forecasts suggest higher probabilities of successful seedling establishment. Climate-change projections are key to the application of current environmental models for development of mitigation and adaptation strategies and for management practices that require a multidecadal planning horizon. Adoption of new weather technology will require collaboration between land managers and revegetation specialists and modifications to the way we currently plan and conduct rangeland rehabilitation and restoration in the Intermountain West.

  4. 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.

  5. Guess Where? Actor-Supervision for Spatiotemporal Action Localization

    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 term "patient centered," "patient centric," or "patient centricity" is increasingly used in the scientific literature in a wide variety of contexts. Generally, patient centric medicines are recognized as an essential contributor to healthy aging and the overall patient's quality of life and life expectancy. Besides the selection of the appropriate type of drug substance and strength for a particular indication in a particular patient, due attention must be paid that the pharmaceutical drug product design is also adequately addressing the particular patient's needs, i.e., assuring adequate patient adherence and the anticipate drug safety and effectiveness. Relevant pharmaceutical design aspects may e.g., involve the selection of the route of administration, the tablet size and shape, the ease of opening the package, the ability to read the user instruction, or the ability to follow the recommended (in-use) storage conditions. Currently, a harmonized definition on patient centric drug development/design has not yet been established. To stimulate scientific research and discussions and the consistent interpretation of test results, it is essential that such a definition is established. We have developed a first draft definition through various rounds of discussions within an interdisciplinary AAPS focus group of experts. This publication summarizes the outcomes and is intended to stimulate further discussions with all stakeholders towards a common definition of patient centric pharmaceutical drug product design that is useable across all disciplines involved.

  11. 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.

  12. Being or Becoming: Toward an Open-System, Process-Centric Model of Personality.

    Science.gov (United States)

    Giordano, Peter J

    2015-12-01

    Mainstream personality psychology in the West neglects the investigation of intra-individual process and variation, because it favors a Being over a Becoming ontology. A Being ontology privileges a structural (e.g., traits or selves) conception of personality. Structure-centric models in turn suggest nomothetic research strategies and the investigation of individual and group differences. This article argues for an open-system, process-centric understanding of personality anchored in an ontology of Becoming. A classical Confucian model of personality is offered as an example of a process-centric approach for investigating and appreciating within-person personality process and variation. Both quantitative and qualitative idiographic strategies can be used as methods of scientific inquiry, particularly the exploration of the Confucian exemplar of psychological health and well-being.

    Gülşen YAYLI

    2015-07-01

    Full Text Available The environmental problems are one of the issues that intensively occupy the agenda of humankind. This fact mainly derives from the ambiguity of the s pan and the content of the issue. The concept of environmental problems can not be confined to th e soil, air and water pollution for the reason that it covers a scope wider than a classical pollution issues. Initially the form of the relations hip between h uman and nature has been relying on the “consumption at the level of content” which stands for a level that is enough to sustain the living. The perception of the nature used to be described with the metaphor of mother while natural environment was defined as the “mother earth”. However subsequent to natural environment definition of the Cartesian philosophy with its approach to the human nature relationship, the core metaphor to describe the natural environment has changed from the metaphor of “mother” to the “slave” which should serve by any means. The human - nature relationship within the context of ethics, both the parties an d their respective statues bear an importance. In terms of ethics of human - nature relationship, it is possible to mention three main approaches. First one is the anthropo - centric approach. Within the scope of historical process, human - nature relationship is addressed according to anthropo - centric ethics comprehension so human has remained at the center of discussion. Following the change of the perception regarding the issue of environment, new approaches have emerged that give emphasis not only on human beings but also others; on li ving and non - living beings with in the eco - system. In principle, this represents a departure from an anthropo - centric ethics to a new ethic approach which fall s into two categories, bio centric and eco - centric. The theo - centric ethics should also be included to these ethics approaches that are shaped within the sphere of positive sciences. The Abrahamic

    International Nuclear Information System (INIS)

    Chamaret, A.

    2007-06-01

    This thesis aims to appraise the relevance of using an hybrid top-down / bottom-up approach to evaluate mining projects in the perspective of sustainable development. With the advent of corporate social responsibility and sustainable development concepts, new social expectations have appeared towards companies that go beyond a sole requirement of profit earning capacity. If companies do not answer to these expectations, they risk to lose their social legitimacy. Traditionally associated with social, environmental, economical and political impacts and risks, mining activity is particularly concerned by these new issues. Whereas mineral resources needs have never been so high, mining companies are now expected to limit their negative effects and to take into account their different audiences' expectations in order to define, together, the terms of their social license to operate. Considering the diversity of issues, scales, actors and contexts, the challenge is real and necessitates tools to better understand issues and to structure dialogues. Based on the Uranium mines of Arlit (Niger) case study, this work shows that associating participatory approaches to structuration tools and literature propositions, appears as an efficient formula to better organize issues diversity and to build a structured dialogue between mining companies and their stakeholders. First Part aims to present the theoretical, institutional and sectorial contexts of the thesis. Second Part exposes work and results of the evaluation carried out in Niger. And, Third Part, shows the conclusions that can be derived from this work and presents a proposal for an evaluation framework, potentially applicable to other mining sites. (author)

  3. Grid Service for User-Centric Job

    Energy Technology Data Exchange (ETDEWEB)

    Lauret, Jerome

    2009-07-31

    The User Centric Monitoring (UCM) project was aimed at developing a toolkit that provides the Virtual Organization (VO) with tools to build systems that serve a rich set of intuitive job and application monitoring information to the VO’s scientists so that they can be more productive. The tools help collect and serve the status and error information through a Web interface. The proposed UCM toolkit is composed of a set of library functions, a database schema, and a Web portal that will collect and filter available job monitoring information from various resources and present it to users in a user-centric view rather than and administrative-centric point of view. The goal is to create a set of tools that can be used to augment grid job scheduling systems, meta-schedulers, applications, and script sets in order to provide the UCM information. The system provides various levels of an application programming interface that is useful through out the Grid environment and at the application level for logging messages, which are combined with the other user-centric monitoring information in a abstracted “data store”. A planned monitoring portal will also dynamically present the information to users in their web browser in a secure manor, which is also easily integrated into any JSR-compliant portal deployment that a VO might employ. The UCM is meant to be flexible and modular in the ways that it can be adopted to give the VO many choices to build a solution that works for them with special attention to the smaller VOs that do not have the resources to implement home-grown solutions.

    Alzahrani, Bander A.; Reed, Martin J.; Vassilakis, Vassilios G.

    2015-01-01

    Line Speed Publish/Subscribe Inter-networking (LIPSIN) is one of the proposed forwarding mechanisms in Information Centric Networking (ICN). It is a stateless source-routing approach based on Bloom filters. However, it has been shown that LIPSIN is vulnerable to brute-force attacks which may lead to distributed denial-of-service (DDoS) attacks and unsolicited messages. In this work, we propose a new forwarding approach that maintains the advantages of Bloom filter based forwarding while allow...

  9. Agile IT: Thinking in User-Centric Models

    Science.gov (United States)

    Margaria, Tiziana; Steffen, Bernhard

    We advocate a new teaching direction for modern CS curricula: extreme model-driven development (XMDD), a new development paradigm designed to continuously involve the customer/application expert throughout the whole systems' life cycle. Based on the `One-Thing Approach', which works by successively enriching and refining one single artifact, system development becomes in essence a user-centric orchestration of intuitive service functionality. XMDD differs radically from classical software development, which, in our opinion is no longer adequate for the bulk of application programming - in particular when it comes to heterogeneous, cross organizational systems which must adapt to rapidly changing market requirements. Thus there is a need for new curricula addressing this model-driven, lightweight, and cooperative development paradigm that puts the user process in the center of the development and the application expert in control of the process evolution.

  10. 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.

  13. Burst Diplomacy The Diplomacies of Foreign Policy: Actors and Methods

    Directory of Open Access Journals (Sweden)

    Guillaume Devin

    2010-12-01

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

    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.

    Buß, C.; Heinisch, J.

    2013-09-01

    High precision optics depend on precisely aligned lenses. The shift and tilt of individual lenses as well as the air gap between elements require accuracies in the single micron regime. These accuracies are hard to meet with traditional assembly methods. Instead, lathe centering can be used to machine the mount with respect to the optical axis. Using a diamond turning process, all relevant errors of single mounted lenses can be corrected in one post-machining step. Building on the OptiCentric® and OptiSurf® measurement systems, Trioptics has developed their first lathe centering machines. The machine and specific design elements of the setup will be shown. For example, the machine can be used to turn optics for i-line steppers with highest precision.

    The objective of the international Chromosome-Centric Human Proteome Project (C-HPP) is to map and annotate all proteins encoded by the genes on each human chromosome. The C-HPP consortium was established to organize a collaborative network among the research teams responsible for protein mapping of individual chromosomes and to identify compelling biological and genetic mechanisms influencing colocated genes and their protein products. The C-HPP aims to foster the development of proteome analysis and integration of the findings from related molecular -omics technology platforms through collaborations among universities, industries, and private research groups. The C-HPP consortium leadership has elicited broad input for standard guidelines to manage these international efforts more efficiently by mobilizing existing resources and collaborative networks. The C-HPP guidelines set out the collaborative consensus of the C-HPP teams, introduce topics associated with experimental approaches, data production, quality control, treatment, and transparency of data, governance of the consortium, and collaborative benefits. A companion approach for the Biology and Disease-Driven HPP (B/D-HPP) component of the Human Proteome Project is currently being organized, building upon the Human Proteome Organization's organ-based and biofluid-based initiatives (www.hupo.org/research). The common application of these guidelines in the participating laboratories is expected to facilitate the goal of a comprehensive analysis of the human proteome.

    2015-05-01

    Full Text Available Research-based Learning (RbL extends Inquiry and Project-based Learning by facilitating an early stage exposure and training for future scientists through authentic research activities. In this paper, an iterative problem-centric RbL process is introduced, and its activities and management aspects are described. The process helps implement course-integrated research systematically and practically. Furthermore, the novel process follows constructivist methods in incorporating inquiry, scaffolding, open-ended projects, as well as a goal oriented learning approach. The RbL process is adopted in two advanced computing courses, at two different universities: a leading comprehensive Western university and a new university in a developing country. The paper summarizes new lessons learned in these rewarding experiences. In particular, the instructor should help students start their projects, by providing them with previous work or data and pre-approving the papers to review by students. He should also maintain a continuous feedback to and from students to keep the students motivated and help the instructor refine and adapt the RBL process. We note that research collaborators can help students in identifying the research topics early. The paper also shows how to alleviate difficulties that may be encountered by students who find the novel approach demanding, and consequently it also helps the instructors better manage the course contents.

    2016-08-16

    For targeted proteomics to be broadly adopted in biological laboratories as a routine experimental protocol, wet-bench biologists must be able to approach SRM assay design in the same way they approach biological experimental design. Most often, biological hypotheses are envisioned in a set of protein interactions, networks and pathways. We present a plugin for the popular Skyline tool that presents public mass spectrometry data in a pathway-centric view to assist users in browsing available data and determining how to design quantitative experiments. Selected proteins and their underlying mass spectra are imported to Skyline for further assay design (transition selection). The same plugin can be used for hypothesis-drive DIA data analysis, again utilizing the pathway view to help narrow down the set of proteins which will be investigated. The plugin is backed by the PNNL Biodiversity Library, a corpus of 3 million peptides from >100 organisms, and the draft human proteome. Users can upload personal data to the plugin to use the pathway navigation prior to importing their own data into Skyline.

  13. Business models for Serious Games developers - transition from a product centric to a service centric approach.

    Directory of Open Access Journals (Sweden)

    Jannicke Baalsrud Hauge

    2014-02-01

    Full Text Available In the context of the serious games industry, up to now the most commonly used BM among developers representing SMEs consists in offering an individual product to the customer, based on tailored one-of a kind production. Such production has high costs and low re-usability and leads to a long time-to-market. For an industry dealing with products highly dependent on technological advances, this implies high risks for failure and thus being put out of business. Consequently, an increasing number of Serious Games developers are struggling to survive. These trends are not specific for the SG development sector, but can actually be observed in several others, like software industry as well as the manufacturing industry, where a transition to less product-oriented BM can be observed. This article is based on an analysis of cases studies to outline how such a transition might be possible also within serious game industry, but also to discuss the threats and opportunities of the transition, both based on case studies as well as on comparison with experiences in other industries

  16. 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.

  17. [Social actors and phenomenologic modelling].

    Science.gov (United States)

    Laflamme, Simon

    2012-05-01

    The phenomenological approach has a quasi-monopoly in the individual and subjectivity analyses in social sciences. However, the conceptual apparatus associated with this approach is very restrictive. The human being has to be understood as rational, conscious, intentional, interested, and autonomous. Because of this, a large dimension of human activity cannot be taken into consideration: all that does not fit into the analytical categories (nonrational, nonconscious, etc.). Moreover, this approach cannot really move toward a relational analysis unless it is between individuals predefined by its conceptual apparatus. This lack of complexity makes difficult the establishment of links between phenomenology and systemic analysis in which relation (and its derivatives such as recursiveness, dialectic, correlation) plays an essential role. This article intends to propose a way for systemic analysis to apprehend the individual with respect to his complexity.

    Patients with head and neck cancer face a number of challenges in terms of treatment, cure of their underlying malignant condition, and quality of survivorship. This presentation will focus on the patient perception of both the quality of care and the empathy and availability of the head and neck oncology team. It has become evident that the quality of survivorship plays a central role in the patient's decision-making process. The process of decision making by the patient facing head and neck cancer and the impact on treatment choices will be explored. The ability of the patient and her or his support system to navigate through the increasingly complicated health care system will be considered, with an emphasis on strategies for success. Finally, the role of the of the head and neck surgeon, and the need for physician wellness in predicating successful patient outcomes will be considered. The ultimate goal of achieving optimal care, superior patient outcomes, and patient satisfaction is the true objective of the concept of living in a patient-centric universe.

    Electronic Laboratory Notebooks (ELNs) are progressively replacing traditional paper books in both commercial research establishments and academic institutions. University researchers require specific features from ELNs, given the need to promote cross-institutional collaborative working, to enable the sharing of procedures and results, and to facilitate publication. The LabTrove ELN, which we use as our exemplar, was designed to be researcher-centric ( i.e. , not only aimed at the individual researcher's basic needs rather than to a specific institutional or subject or disciplinary agenda, but also able to be tailored because it is open source). LabTrove is being used in a heterogeneous set of academic laboratories, for a range of purposes, including analytical chemistry, X-ray studies, drug discovery and a biomaterials project. Researchers use the ELN for recording experiments, preserving data collected, and for project coordination. This perspective article describes the experiences of those researchers from several viewpoints, demonstrating how a web-based open source electronic notebook can meet the diverse needs of academic researchers.

  1. A Liver-Centric Multiscale Modeling Framework for Xenobiotics.

    Directory of Open Access Journals (Sweden)

    James P Sluka

    Full Text Available We describe a multi-scale, liver-centric in silico modeling framework for acetaminophen pharmacology and metabolism. We focus on a computational model to characterize whole body uptake and clearance, liver transport and phase I and phase II metabolism. We do this by incorporating sub-models that span three scales; Physiologically Based Pharmacokinetic (PBPK modeling of acetaminophen uptake and distribution at the whole body level, cell and blood flow modeling at the tissue/organ level and metabolism at the sub-cellular level. We have used standard modeling modalities at each of the three scales. In particular, we have used the Systems Biology Markup Language (SBML to create both the whole-body and sub-cellular scales. Our modeling approach allows us to run the individual sub-models separately and allows us to easily exchange models at a particular scale without the need to extensively rework the sub-models at other scales. In addition, the use of SBML greatly facilitates the inclusion of biological annotations directly in the model code. The model was calibrated using human in vivo data for acetaminophen and its sulfate and glucuronate metabolites. We then carried out extensive parameter sensitivity studies including the pairwise interaction of parameters. We also simulated population variation of exposure and sensitivity to acetaminophen. Our modeling framework can be extended to the prediction of liver toxicity following acetaminophen overdose, or used as a general purpose pharmacokinetic model for xenobiotics.

  2. Action recognition is sensitive to the identity of the actor.

    2017-09-01

    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.

    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....

    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.

  8. Overview on Patient Centricity in Cancer Care

    2017-10-01

    Full Text Available Successful implementation of treatment in cancer care partially depends on how patients' perspectives are taken into account, as preferences of health care professionals and patients may differ. Objectives of this exploratory research were (I to identify patient preferences and values (PPVs in cancer care as indicated by patient organizations (POs, (II to determine how these PPVs are captured in cancer care guidelines and (III to review how guidelines take into account these PPVs. Based on a survey developed and completed by 19 POs, a literature review was conducted to analyse how patient perspectives are incorporated in oncology treatment guidelines. Based on survey results traditional health technology assessment value propositions of oncology care, such as extended life, treatment-free remission and pain reduction, were also highly rated by POs. However, the heterogeneity of cancer PPVs were clearly reflected in the survey results. PPVs in cancer care guidelines were mostly limited to those micro-level aspects that are strictly related to health care provision, such as side-effects and comorbidities. Patient experience, emotional support and convenience of care were relatively neglected fields in the reviewed guidelines. Patient engagement was rarely presented in the guideline development phase. POs believe that patients should be encouraged to take an active role in their own care due to the heterogeneity of cancer patients and PPVs. Even if patient-centricity is a leading paradigm in cancer policy, based on our research it is not yet standard practice to include patients or POs at all appropriate levels of decision-making processes that are related to their health and well-being. Patient engagement should be an integral part of cancer care decision-making. This complexity must be reflected throughout policy making, avoiding a population level “one-size-fits-all” solution.

  15. The role of social actors in times of crisis / El papel de los actores sociales en tiempos de crisis

    Directory of Open Access Journals (Sweden)

    Iván Medina Iborra

    2013-10-01

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

  2. 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.

    2000-02-01

    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

  4. Reuse-centric Requirements Analysis with Task Models, Scenarios, and Critical Parameters

    Directory of Open Access Journals (Sweden)

    Cyril Montabert

    2007-02-01

    Full Text Available This paper outlines a requirements-analysis process that unites task models, scenarios, and critical parameters to exploit and generate reusable knowledge at the requirements phase. Through the deployment of a critical-parameter-based approach to task modeling, the process yields the establishment of an integrative and formalized model issued from scenarios that can be used for requirements characterization. Furthermore, not only can this entity serve as interface to a knowledge repository relying on a critical-parameter-based taxonomy to support reuse but its characterization in terms of critical parameters also allows the model to constitute a broader reuse solution. We discuss our vision for a user-centric and reuse-centric approach to requirements analysis, present previous efforts implicated with this line of work, and state the revisions brought to extend the reuse potential and effectiveness of a previous iteration of a requirements tool implementing such process. Finally, the paper describes the sequence and nature of the activities involved with the conduct of our proposed requirements-analysis technique, concluding by previewing ongoing work in the field that will explore the feasibility for designers to use our approach.

    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.

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.

    2017-11-01

    In computer science research, ontologies are commonly utilised to create a unified abstract across many rich and different fields. In this paper, we apply the concept to the customer centric domain of digital services analytics and present an analytics solution ontology. The essence is based from traditional Entity Relationship Diagram (ERD), which then was abstracted out to cover wider areas on customer centric digital services. The ontology we developed covers both static aspects (customer identifiers) and dynamic aspects (customer's temporal interactions). The structure of the customer scape is modeled with classes that represent different types of customer touch points, ranging from digital and digital-stamps which represent physical analogies. The dynamic aspects of customer centric digital service are modeled with a set of classes, with the importance is represented in different associations involving establishment and termination of the target interaction. The realized ontology can be used in development of frameworks for customer centric applications, and for specification of common data format used by cooperating digital service applications.

    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.

    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.

  1. The driver, the road, the rules … and the rest? A systems-based approach to young driver road safety.

    Science.gov (United States)

    Scott-Parker, B; Goode, N; Salmon, P

    2015-01-01

    The persistent overrepresentation of young drivers in road crashes is universally recognised. A multitude of factors influencing their behaviour and safety have been identified through methods including crash analyses, simulated and naturalistic driving studies, and self-report measures. Across the globe numerous, diverse, countermeasures have been implemented; the design of the vast majority of these has been informed by a driver-centric approach. An alternative approach gaining popularity in transport safety is the systems approach which considers not only the characteristics of the individual, but also the decisions and actions of other actors within the road transport system, along with the interactions amongst them. This paper argues that for substantial improvements to be made in young driver road safety, what has been learnt from driver-centric research needs to be integrated into a systems approach, thus providing a holistic appraisal of the young driver road safety problem. Only then will more effective opportunities and avenues for intervention be realised. Copyright © 2014 Elsevier Ltd. All rights reserved.

  3. AlphaSpace: Fragment-Centric Topographical Mapping To Target Protein–Protein Interaction Interfaces

    Science.gov (United States)

    2016-01-01

    Inhibition of protein–protein interactions (PPIs) is emerging as a promising therapeutic strategy despite the difficulty in targeting such interfaces with drug-like small molecules. PPIs generally feature large and flat binding surfaces as compared to typical drug targets. These features pose a challenge for structural characterization of the surface using geometry-based pocket-detection methods. An attractive mapping strategy—that builds on the principles of fragment-based drug discovery (FBDD)—is to detect the fragment-centric modularity at the protein surface and then characterize the large PPI interface as a set of localized, fragment-targetable interaction regions. Here, we introduce AlphaSpace, a computational analysis tool designed for fragment-centric topographical mapping (FCTM) of PPI interfaces. Our approach uses the alpha sphere construct, a geometric feature of a protein’s Voronoi diagram, to map out concave interaction space at the protein surface. We introduce two new features—alpha-atom and alpha-space—and the concept of the alpha-atom/alpha-space pair to rank pockets for fragment-targetability and to facilitate the evaluation of pocket/fragment complementarity. The resulting high-resolution interfacial map of targetable pocket space can be used to guide the rational design and optimization of small molecule or biomimetic PPI inhibitors. PMID:26225450

    Full Text Available This study utilized participatory action research approaches to construct a follower-centric framework for measuring influences on sexual decision making by youth members of a church organization. Participants were Batswana Pentecostal church members self-reporting on their engagement in pre-marital sex (n = 68, females = 62%; age range 15–23 years; median age = 20.3 years from eight of 26 randomly selected congregations. They completed a multi-stage concept mapping process that included free listing of statements of potential influences on their sexual decisions. They then sorted the statements into groupings similar in meaning to them, and rated the same statements for relative importance to their sexual decisions. Multidimensional scaling and hierarchical cluster analysis of the data yielded a five cluster solution in which church teachings emerged as most salient to the teenagers’ sexual decision making followed by future orientation, community norms, knowledge about HIV/AIDS and prevention education. While the youth believed to be influenced by religion teachings on primary sexual abstinence, they self-reported with pre-marital sex. This suggests a need for secondary abstinence education with them to reduce their risk for STIs/HIV and unwanted pregnancies. Concept mapping is serviceable to construct frameworks and to identify content of follower-centric influences on sexual decision making by church youth members.

  6. Neoliberalism and political actors in contemporary Argentina

    2017-11-01

    Full Text Available In this paper we set out a critical reading of the literature on political neoliberal actors in Argentina. We consider that the concentration of these studies in the national level has to do with a definition of neoliberalism as a set of economical and structural macro politics. We propose to define neoliberalism as a technology of government that intends to hegemonize an “enterprise form” in different social spheres, articulating a symbolical framework in a contingent and contentious way. This insight allows analyzing neoliberal identification processes as heterogeneous trajectories with diverse geographic and temporal scopes.

    Guideline-based clinical decision support is an emerging paradigm to help reduce error, lower cost, and improve quality in evidence-based medicine. The free and open source (FOS) approach is a promising alternative for delivering cost-effective information technology (IT) solutions in health care. In this paper, we survey the current FOS enabling technologies for patient-centric, guideline-based care, and discuss the current trends and future directions of their role in clinical decision support. We searched PubMed, major biomedical informatics websites, and the web in general for papers and links related to FOS health care IT systems. We also relied on our background and knowledge for specific subtopics. We focused on the functionalities of guideline modeling tools, and briefly examined the supporting technologies for terminology, data exchange and electronic health record (EHR) standards. To effectively support patient-centric, guideline-based care, the computerized guidelines and protocols need to be integrated with existing clinical information systems or EHRs. Technologies that enable such integration should be accessible, interoperable, and scalable. A plethora of FOS tools and techniques for supporting different knowledge management and quality assurance tasks involved are available. Many challenges, however, remain in their implementation. There are active and growing trends of deploying FOS enabling technologies for integrating clinical guidelines, protocols, and pathways into the main care processes. The continuing development and maturation of such technologies are likely to make increasingly significant contributions to patient-centric, guideline-based clinical decision support.

    Facing the rapidly changing business environments, implementation of flexible business process is crucial, but difficult especially in data-intensive application areas. This study aims to provide scalable and easily accessible information resources to leverage business process management. In this article, with a resource-oriented approach, enterprise data resources are represented as data-centric Web services, grouped on-demand of business requirement and configured dynamically to adapt to changing business processes. First, a configurable architecture CIRPA involving information resource pool is proposed to act as a scalable and dynamic platform to virtualise enterprise information resources as data-centric Web services. By exposing data-centric resources as REST services in larger granularities, tenant-isolated information resources could be accessed in business process execution. Second, dynamic information resource pool is designed to fulfil configurable and on-demand data accessing in business process execution. CIRPA also isolates transaction data from business process while supporting diverse business processes composition. Finally, a case study of using our method in logistics application shows that CIRPA provides an enhanced performance both in static service encapsulation and dynamic service execution in cloud computing environment.

    2017-01-01

    Full Text Available Content Centric Networking (CCN is an effective communication paradigm that well matches the features of wireless environments. To be considered a viable candidate in the emerging wireless networks, despite the clear benefits of location-independent security, CCN must at least have parity with existing solutions for confidential and anonymous communication. This paper designs a new cryptographic scheme, called Asymmetric Index Encapsulation (AIE, that enables the router to test whether an encapsulated header matches the token without learning anything else about both of them. We suggest using the AIE as the core protocol of anonymous Content Centric Networking. A construction of AIE which strikes a balance between efficiency and security is given. The scheme is proved to be secure based on the DBDH assumption in the random oracle with tight reduction, while the encapsulated header and the token in our system consist of only three elements.

    Research purpose: This study aimed to investigate how scenario-based planning (a strictly cognitive management tool can be combined with organisational change navigation (a practice addressing the emotionality of change and how this integrated process should be aligned with the prerequisites imposed by a developing country context and an Afro-centric leadership perspective in order to make the process more context relevant and aligned. Motivation for the study: The integration of organisational change navigation with conventional scenario based planning, as well as the incorporation of the perquisites of a developing countries and an Afro-centric leadership perspective, will give organisations a more robust, holistic strategic management tool that will add significantly more value within a rapidly, radically and unpredictably changing world. Research design, approach and method: The adopted research approach comprised a combination of the sourcing of the latest thinking in the literature (the ‘theory’ as well as the views of seasoned practitioners of scenario planning (the ‘practice’ through an iterative research process, moving between theory and practice, back to practice and finally returning to theory in order to arrive at a validated expanded and enhanced scenario-based planning process which is both theory and practice ‘proof’. Main findings: A management tool incorporating the change navigation and the unique features of developing countries and Afro-centric leadership was formulated and empirically validated. This management tool is referred to as a change navigation based, scenario planning process (CNBSPP. Practical/managerial implications: CNBSPP is available for use by organisations wishing to apply a strategic planning tool that fits within a developing country context and an Afro-centric leadership approach. Contribution/value add: The research makes a unique contribution to the current level of knowledge by integrating two disciplines

  1. 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.

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

    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

    In several countries, traditional market lose in competition with supermarket. Supermarket has several advantages compared with traditional market. It can provides consumers with lower prices, offer more varieties of products and higher quality products than traditional retailers, has more comfortable place for shopping. In Malang City, the existence of traditional traders was threatened. In a competitive retail market, traditional traders get less protection from the Government of Malang Municipality. Massive demonstrations conducted by traditional traders along with other society elements unable to stem the rapid growth of modern retail. This paper focus on the interaction of Malang Municipality actors in the local retail market competition. How those interaction can make imbalance retail market competition. The author uses descriptive-analytic method with a qualitative approach in this work. As a result, the interaction tend to produce imbalance retail market competition. Interaction between legislative, executive, bureaucracy and mass media tend to support modern retail growth than traditional one.

    2018-05-01

    Full Text Available Olive oil consumption has grown substantially in recent years, due in part to the fact that olive oil is healthy. Much of the global olive oil production comes from the rural areas of Jaén in southern Spain. Surrounding this industry, services such as oleotourism are increasing. This paper aims to identify the key elements supporting the development of oleotourism. After a preliminary exploratory analysis of the existing data, a qualitative analysis was performed with actors directly involved in the industry in Jaén. The results helped us define the level of the stakeholders’ involvement and the sustainability, the opportunities, and the constraints affecting oleotourism in this area. The practical implications of this investigation can be useful for governing agencies, local firms, and the tourism industry in support of oleotourism development.

  9. Lone-actor Terrorism and Impulsivity.

    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.

    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.

    Künzi, Julien; Petkovic, M.; Koster, Paul

    2009-02-01

    In this paper we address the problem of privacy protection and trust enhancement in a distributed healthcare eco system. Increased trust in other parties of the eco system encourages medical entities to share data. This increases the availability of data and consequently improves the general quality of health care. We present two different solutions to the above described problem, both being developed using the DICOM standard (Digital Imaging and Communications in Medicine). The first approach, which is partially relying on legislation, uses sticky policies and commitment protocols to enhance trust. We propose to attach the access control policies to the data in the DICOM files. Furthermore, the source of data disclosure makes sure that the destination commits to enforce the policies by obtaining a signature on the policies and thus providing a proof of the commitment by the destination. The second approach aims at increasing trust by technical enforcement. For this purpose, digital rights management (DRM) technology is used. We demonstrate that it is possible to create a DICOM DRM container using the tools provided by this standard, hence still guaranteeing backward compatibility.

    Full Text Available The need for high-quality out-of-hospital healthcare is a known socioeconomic problem. Exploiting ICT's evolution, ad-hoc telemedicine solutions have been proposed in the past. Integrating such ad-hoc solutions in order to cost-effectively support the entire healthcare cycle is still a research challenge. In order to handle the heterogeneity of relevant information and to overcome the fragmentation of out-of-hospital instrumentation in person-centric healthcare systems, a shared and open source interoperability component can be adopted, which is ontology driven and based on the semantic web data model. The feasibility and the advantages of the proposed approach are demonstrated by presenting the use case of real-time monitoring of patients' health and their environmental context.

  13. Secure Network-Centric Aviation Communication (SNAC)

    2017-01-01

    The existing National Airspace System (NAS) communications capabilities are largely unsecured, are not designed for efficient use of spectrum and collectively are not capable of servicing the future needs of the NAS with the inclusion of new operators in Unmanned Aviation Systems (UAS) or On Demand Mobility (ODM). SNAC will provide a ubiquitous secure, network-based communications architecture that will provide new service capabilities and allow for the migration of current communications to SNAC over time. The necessary change in communication technologies to digital domains will allow for the adoption of security mechanisms, sharing of link technologies, large increase in spectrum utilization, new forms of resilience and redundancy and the possibly of spectrum reuse. SNAC consists of a long term open architectural approach with increasingly capable designs used to steer research and development and enable operating capabilities that run in parallel with current NAS systems.

    Between 2005 and 2010 BT underwent a major transformation from a company with a special section devoted to 'older and disabled consumers' to a company with an inclusive design strategy. The mainstreaming of these issues responded to a demand for better, more user-friendly communications products and growing awareness of the importance of previously marginalised consumer groups. It also took place alongside the development and publication of BS7000-6, a guide to inclusive design management. Based on several product design case studies, this paper reflects on how and why this transformation was seen as necessary for future success, and how the transformation was achieved. The evolution of BT's approach has continued since, but this paper looks back in time, and documents the transformation up to 2010 and reflects the state of the company in 2010 rather than at the time of publication.

    2012-06-29

    In the age of massive parallelism, the focus of performance analysis has switched from the processor and related structures to the memory and I/O resources. Adapting to this new reality, a performance analysis tool has to provide a way to analyze resource usage to pinpoint existing and potential problems in a given application. This paper provides an overview of the Memory Observant Data Analysis (MODA) tool, a memory-centric tool first implemented on the Cray XMT supercomputer. Throughout the paper, MODA's capabilities have been showcased with experiments done on matrix multiply and Graph-500 application codes.

  17. Physical Training Strategies for Military Women's Performance Optimization in Combat-Centric Occupations.

    Nindl, Bradley C

    2015-11-01

    The physiological differences, particularly of upper-body strength and power, between women and men, and the rigors of combat-centric occupational demands would seem to place women at a significant disadvantage, as the U.S. military opens up previously closed combat-arms military occupational specialties (MOSs) to women. This inherent disadvantage can be significantly mitigated by implementing effective and comprehensive physical training (PT) regimens for women targeting those fitness components most critical for those tasks considered most essential for solider warfighting duties (i.e., strength and power). Regrettably, the military historical and legacy overemphasis on aerobic fitness and on "field expediency" as the major criteria for implementing training have limited the extent to which the military has fully operationalized state-of-the-science PT policies. This continued legacy approach could be problematic regarding fully enhancing women's abilities to perform physically demanding combat-centric occupations and could place the successful integration of women into ground combat MOSs at significant risk. Seminal studies from the literature indicate that (a) a minimum of 6 months of periodized combined resistance/endurance training preparedness is recommended for untrained women considering entering combat-arms MOS training; (b) any comprehensive PT program should incorporate and emphasize progressive load carriage training; (c) a greater emphasis on upper body on strength/power development in military women is needed; (d) heavy resistance training in the range of 3-8 repetition maximum sets should be incorporated into training programs to target type II motor units and muscle fibers (those fibers that produce the most force and have the greatest capacity to hypertrophy); (e) low-volume, high-intensity interval training should be considered as a time-efficient training method to improve aerobic fitness while protecting against lower-body musculoskeletal

  20. Operationalizing social safeguards in REDD+: actors, interests and ideas

    2012-01-01

    “REDD+” is a mechanism created under the United Nations Framework Convention on Climate Change (UNFCCC) for Reducing {carbon} Emissions from Deforestation and Degradation and forest enhancement. In addition, REDD+ “safeguards” are intended to protect non-carbon forest values. While REDD+ countries are formally requested to provide information on safeguards, there is as yet no agreement on the relative priority of carbon versus non-carbon values, and the appropriate level of safeguard standardization. This, we argue, has allowed REDD+ to function as a “boundary object” spanning disparate priorities. Meanwhile, the contestation of these priorities has been displaced from intergovernmental processes to the various organizations involved in operationalizing REDD+ activities. This article applies a set of organizational, substantive and conceptual typologies to compare differences in the balance of actors, interests and ideas across these organizations. It finds that multi-lateral funding programs have drawn heavily on existing safeguards for international aid, while private certification schemes have specialized in different niche priorities at the project level. In regards to the substance of safeguard requirements, the involvement of donors and investors appears correlated with a stronger emphasis on carbon and risk mitigation while greater NGO involvement and the decoupling of safeguards design from REDD+ funding appear correlated with greater emphasis on social rights and benefits. These findings have several critical implications for future REDD+ activities. Firstly, the choice of organizations involved in defining, funding and verifying safeguard activities, and the balance of actors in their governing structures, are likely to influence the relative emphasis on non-carbon values. Secondly, a diversity of approaches to disbursing REDD+ incentives may be necessary to maintain widespread support for REDD+. Thirdly, it remains to be seen whether REDD

    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.

  10. On Lifecycle Constraints of Artifact-Centric Workflows

    Science.gov (United States)

    Kucukoguz, Esra; Su, Jianwen

    Data plays a fundamental role in modeling and management of business processes and workflows. Among the recent "data-aware" workflow models, artifact-centric models are particularly interesting. (Business) artifacts are the key data entities that are used in workflows and can reflect both the business logic and the execution states of a running workflow. The notion of artifacts succinctly captures the fluidity aspect of data during workflow executions. However, much of the technical dimension concerning artifacts in workflows is not well understood. In this paper, we study a key concept of an artifact "lifecycle". In particular, we allow declarative specifications/constraints of artifact lifecycle in the spirit of DecSerFlow, and formulate the notion of lifecycle as the set of all possible paths an artifact can navigate through. We investigate two technical problems: (Compliance) does a given workflow (schema) contain only lifecycle allowed by a constraint? And (automated construction) from a given lifecycle specification (constraint), is it possible to construct a "compliant" workflow? The study is based on a new formal variant of artifact-centric workflow model called "ArtiNets" and two classes of lifecycle constraints named "regular" and "counting" constraints. We present a range of technical results concerning compliance and automated construction, including: (1) compliance is decidable when workflow is atomic or constraints are regular, (2) for each constraint, we can always construct a workflow that satisfies the constraint, and (3) sufficient conditions where atomic workflows can be constructed.

  11. User-centric incentive design for participatory mobile phone sensing

    Gao, Wei; Lu, Haoyang

    2014-05-01

    Mobile phone sensing is a critical underpinning of pervasive mobile computing, and is one of the key factors for improving people's quality of life in modern society via collective utilization of the on-board sensing capabilities of people's smartphones. The increasing demands for sensing services and ambient awareness in mobile environments highlight the necessity of active participation of individual mobile users in sensing tasks. User incentives for such participation have been continuously offered from an application-centric perspective, i.e., as payments from the sensing server, to compensate users' sensing costs. These payments, however, are manipulated to maximize the benefits of the sensing server, ignoring the runtime flexibility and benefits of participating users. This paper presents a novel framework of user-centric incentive design, and develops a universal sensing platform which translates heterogenous sensing tasks to a generic sensing plan specifying the task-independent requirements of sensing performance. We use this sensing plan as input to reduce three categories of sensing costs, which together cover the possible sources hindering users' participation in sensing.

  12. SPARTex: A Vertex-Centric Framework for RDF Data Analytics

    KAUST Repository

    Abdelaziz, Ibrahim

    2015-08-31

    A growing number of applications require combining SPARQL queries with generic graph search on RDF data. However, the lack of procedural capabilities in SPARQL makes it inappropriate for graph analytics. Moreover, RDF engines focus on SPARQL query evaluation whereas graph management frameworks perform only generic graph computations. In this work, we bridge the gap by introducing SPARTex, an RDF analytics framework based on the vertex-centric computation model. In SPARTex, user-defined vertex centric programs can be invoked from SPARQL as stored procedures. SPARTex allows the execution of a pipeline of graph algorithms without the need for multiple reads/writes of input data and intermediate results. We use a cost-based optimizer for minimizing the communication cost. SPARTex evaluates queries that combine SPARQL and generic graph computations orders of magnitude faster than existing RDF engines. We demonstrate a real system prototype of SPARTex running on a local cluster using real and synthetic datasets. SPARTex has a real-time graphical user interface that allows the participants to write regular SPARQL queries, use our proposed SPARQL extension to declaratively invoke graph algorithms or combine/pipeline both SPARQL querying and generic graph analytics.

    Information Centric Networks (ICN) is the new paradigm that envisages to shift the Internet away from its existing Point-to-Point architecture to a data centric, where communication is based on named hosts rather than the information stored on these hosts. Name Resolution is the center of attraction for ICN, where Named Data Objects (NDO) are used for identifying the information and guiding for routing or forwarding inside ICN. Recently, several researches use distributed NRS to overcome the problem of interest flooding, congestion and overloading. Yet the distribution of NRS is based on random distribution. How to distribute the NRS is still an important and challenging problem. In this work, we address the problem of distribution of NRS by proposing a new mechanism called Distributed Name Resolution System (DNRS), by considering the time of publishing the NDOs in the NRS. This mechanism partitions the network to distribute the workload among NRSs by increasing storage capacity. In addition, partitioning the network increases flexibility and scalability of NRS. We evaluate the effectiveness of our proposed mechanism, which achieves lesser end-to-end delay with more average throughputs compared to random distribution of NRS without disturbing the underlying routing or forwarding strategies.

    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.

    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.

    2017-01-01

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

  18. Sensor-centric calibration and characterization of the VIIRS Ocean Color bands using Suomi NPP operational data

    Science.gov (United States)

    Pratt, P.

    2012-12-01

    Ocean color bands on VIIRS span the visible spectrum and include two NIR bands. There are sixteen detectors per band and two HAM (Half-angle mirror) sides giving a total of thirty two independent systems. For each scan, thirty two hundred pixels are collected and each has a fixed specific optical path and a dynamic position relative to the earth geoid. For a given calibration target where scene variation is minimized, sensor characteristics can be observed. This gives insight into the performance and calibration of the instrument from a sensor-centric perspective. Calibration of the blue bands is especially challenging since there are few blue targets on land. An ocean region called the South Pacific Gyre (SPG) was chosen for its known stability and large area to serve as a calibration target for this investigation. Thousands of pixels from every granule that views the SPG are collected daily through an automated system and tabulated along with the detector, HAM and scan position. These are then collated and organized in a sensor-centric set of tables. The data are then analyzed by slicing by each variable and then plotted in a number of ways over time. Trends in the data show that the VIIRS sensor is largely behaving as expected according to heritage data and also reveals weaknesses where additional characterization of the sensor is possible. This work by Northrop Grumman NPP CalVal Team is supporting the VIIRS on-orbit calibration and validation teams for the sensor and ocean color as well as providing scientists interested in performing ground truth with results that show which detectors and scan angles are the most reliable over time. This novel approach offers a comprehensive sensor-centric on-orbit characterization of the VIIRS instrument on the NASA Suomi NPP mission.

    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 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.

    We are now in a phase change of the CMS experiment where people are turning more intensely to physics analysis and away from construction. This brings a lot of challenging issues with respect to monitoring of the user analysis. The physicists must be able to monitor the execution status, application and grid-level messages of their tasks that may run at any site within the CMS Virtual Organisation. The CMS Dashboard Task Monitoring project provides this information towards individual analysis users by collecting and exposing a user-centric set of information regarding submitted tasks including reason of failure, distribution by site and over time, consumed time and efficiency. The development was user-driven with physicists invited to test the prototype in order to assemble further requirements and identify weaknesses with the application.

    Full Text Available Knowledge Networks are gaining momentum within cyber world. Knowledge leads to innovation and for this reason organizations focus on research and information gathering in order to gain and improve existing knowledge. This of information era, which is primarily based on world wide web technologies, enables significantly expanded networks of people to communicate and collaborate 'virtually' across teams, across entire organizations and across the world, anytime and anywhere. Innovations in computing and telecommunications have transformed the corporations from structured and manageable types to interwoven network of blurred boundaries such as; ad hoc networks and mobile wireless networks, etc. This study explores knowledge networks in Information Technology and security leaks that are found, as well as measures that are taken to counter this menace which is coming up with optimal Secure Clustered Power Centric node network. The paper concludes these measures, evaluating and integrating them to come up with a secured network design.

    2005-01-01

    Pre-print repositories have seen a significant increase in use over the past fifteen years across multiple research domains. Researchers are beginning to develop applications capable of using these repositories to assist the scientific community above and beyond the pure dissemination of information. The contributions set forth by this paper emphasize a deconstructed publication model where in which the peer-review certification phase of a pre-print is mediated by an OAI-compliant peer-review service. This peer-review service uses a social-network algorithm for determining potential reviewers for a submitted manuscript and for weighting the influence of each participating reviewer’s evaluations. The paper also provides a set of peer-review specific metadata tags that can accompany a pre-prints existing metadata record. The combinations of these contributions provide a unique repository-centric peer-review model within the framework of the current OAI standards existing today.

    Agarwal, Ankur; Henehan, Nathan; Somashekarappa, Vivek; Pandya, A. S.; Kalva, Hari; Furht, Borko

    This chapter discusses an emerging concept of a cloud computing based Patient Centric Medical Information System framework that will allow various authorized users to securely access patient records from various Care Delivery Organizations (CDOs) such as hospitals, urgent care centers, doctors, laboratories, imaging centers among others, from any location. Such a system must seamlessly integrate all patient records including images such as CT-SCANS and MRI'S which can easily be accessed from any location and reviewed by any authorized user. In such a scenario the storage and transmission of medical records will have be conducted in a totally secure and safe environment with a very high standard of data integrity, protecting patient privacy and complying with all Health Insurance Portability and Accountability Act (HIPAA) regulations.

    2010-04-01

    An enterprise data strategy outlines an organization's vision and objectives for improved collection and use of data. We propose generic metrics and quantifiable measures for each of the DoD Net-Centric Data Strategy (NCDS) data goals. Data strategy metrics can be adapted to the business processes of an enterprise and the needs of stakeholders in leveraging the organization's data assets to provide for more effective decision making. Generic metrics are applied to a specific application where logistics supply and transportation data is integrated across multiple functional groups. A dashboard presents a multidimensional view of the current progress to a state where logistics data shared in a timely and seamless manner among users, applications, and systems.

    This work presents a data-centric strategy to meet deadlines in soft real-time applications in wireless sensor networks. This strategy considers three main aspects: (i) The design of real-time application to obtain the minimum deadlines; (ii) An analytic model to estimate the ideal sample size used by data-reduction algorithms; and (iii) Two data-centric stream-based sampling algorithms to perform data reduction whenever necessary. Simulation results show that our data-centric strategies meet deadlines without loosing data representativeness. PMID:22303145

  10. 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.

    2014-08-25

    The Internet of Things (IoT) has inspired solutions that are already available for addressing problems in various application scenarios, such as healthcare, security, emergency support and tourism. However, there is no clear approach to modeling these systems and envisioning their capabilities at the design time. Therefore, the process of designing these systems is ad hoc and its real impact is evaluated once the solution is already implemented, which is risky and expensive. This paper proposes a modeling approach that uses human-centric wireless sensor networks to specify and evaluate models of IoT-based systems at the time of design, avoiding the need to spend time and effort on early implementations of immature designs. It allows designers to focus on the system design, leaving the implementation decisions for a next phase. The article illustrates the usefulness of this proposal through a running example, showing the design of an IoT-based solution to support the first responses during medium-sized or large urban incidents. The case study used in the proposal evaluation is based on a real train crash. The proposed modeling approach can be used to design IoT-based systems for other application scenarios, e.g., to support security operatives or monitor chronic patients in their homes.

    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.

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

    Full Text Available 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.

    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.

  10. Exploring agency beyond humans: the compatibility of Actor-Network Theory (ANT and resilience thinking

    Directory of Open Access Journals (Sweden)

    Angga Dwiartama

    2014-09-01

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

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

    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.

  20. China's Coal Methane: Actors, Structures, Strategies and their Global Impacts

    International Nuclear Information System (INIS)

    Chen, Ke; Charnoz, Olivier

    2012-12-01

    The need for China to alleviate its energy shortage, reduce its dependence on foreign sources and mitigate its climate impact is driving a dire quest for alternative fuels. Coal Mine Methane (CMM), in this context, holds significant potential. While the 11. Five-Year Plan aimed to capture and use 10 billion m"3 per year of CMM by 2010, the country achieved less than a quarter of this. This paper enquires into this puzzling outcome, which bears consequences for the world at large. China is indeed responsible for more than 40% of the world's total un-captured CMM emissions - which act as a greenhouse gas 21 times more potent than CO_2, and whose role in global warming is often underestimated, especially in short- and medium-term climate strategies. While the Chinese central government may have incentive to work towards promoting CMM, the benefits of such policies at the sub-national level are far from self-evident. National CMM policies can have significant economic and social costs at the local level, and thus their implementation can be jeopardized. Implementation of such policies is inherently ambiguous, conflicting, and as such, political. Current research on the Chinese CMM industry has largely focused on its techno-economic aspects, with little if any politico-institutional analyses. As for policy research on the larger Chinese energy sector, this seems sturdily to embody a top-down view: it mostly ends up blaming the country's decentralized governance structure and lack of a stringent implementation chain. Such top-down approaches do not help uncover 'the sinews of war': the range of less formal mechanisms, negotiations and agreements among the local actors, without which implementation does not in fact occur at the sub-national level. Nor do top-down research approaches facilitate inquiry into the way local stakeholders re-frame the meaning, content and impact of CMM policies. More generally, the top-down approaches fail to consider the significance of

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

  3. Planning, Anticipatory Systems, and Kinds of Actors

    2002-09-01

    Anticipation and planning have much in common. Anticipation means being ahead of things. Planning means not only anticipating on things to come, but also trying to determine a course of action to reach a goal. Planning is investigated in many domains, for example, in economy, biology, and in the cognitive sciences. Each of these domains uses its own research methodologies, languages, ontologies, and models. Although there are many differences between the various approaches and models, there must of course also be similarities, since they all deal with establishing a future course of actions to reach a goal. We will compare several planning approaches on a number of aspects, e.g., the kind of entity that makes the plan (natural or artificial), whether the plan is executed by the planner or by another entity, representational issues, and the domain that the plan is executed in. Our article focuses on analytical dimensions in the extended field of planning. We do not discuss empirical results.

  4. The European Union as a Security Actor: Moving Beyond the Second Pillar

    Directory of Open Access Journals (Sweden)

    2009-04-01

    Full Text Available It is suggested in this article that there is a discrepancy between, on the one hand, literature that focuses on the European Union (EU as a security actor and, on the other, contemporary security studies literature. This difference concerns the fact that the literature on the EU as a security actor treats security in a narrower sense than how it is approached in the literature on security studies. Over the past few decades, security studies literature has begun to fully acknowledge that the concept of security has broadened beyond traditional ‘hard’ security concerns and can encompass many different issues, for example the security implications of climate change. However, the literature on the EU as a security actor very often associates security only with the second pillar of the EU’s organisational structure; in particular the intergovernmental cooperation embodied by the Common Foreign and Security Policy (CFSP and the European Security and Defence Policy (ESDP. The main purpose of this article is to utilise the broader security studies approach to security as a means to expand the understanding of security in the context of the EU’s performance on the international stage. This is important because it allows the Union’s �����actorness’ in the field of security to be examined in a more holistic manner.

    Research purpose: This article relates certain changes in HRM over time to the argument that there has been a shift from an industrial paradigm (on which many human resource [HR] systems, practices and theoretical frameworks are still based to a knowledge paradigm (of knowledge work, in which employee knowledge and skills offer compound advantages that are not substitutable which explains a great deal of the variance in changes of the field over time. Motivation for the study: It is argued that in order for the field to move forward, it may needto bring to the surface certain assumptions and differentiate between theoretical frameworkswhen dealing with knowledge work versus non-knowledge work. Research design, approach and method: This article offers a perspective of HR theory development over time. It is a conceptual/perspectives article and is not qualitative nor quantitative in nature. Further research will be able to test the ideas presented here. Practical/managerial implications: Managers and human resources managers need to differentiate between knowledge and non-knowledge work. The latter is associated with increased heterogeneity and complexity, and differences in power relationships, as knowledge work shifts power away from capital into the hands of skilled knowledge labour.

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

    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.

  8. Cultural influences upon advance care planning in a family-centric society.

    Advanced care plans (ACPs) are designed to convey the wishes of patients with regards to their care in the event of incapacity. There are a number of prerequisites for creation of an effective ACP. First, the patient must be aware of their condition, their prognosis, the likely trajectory of the illness, and the potential treatment options available to them. Second, patient input into ACP must be free of any coercive factors. Third, the patient must be able to remain involved in adapting their ACP as their condition evolves. Continued use of familial determination and collusion within the local healthcare system, however, has raised concerns that the basic requirements for effective ACP cannot be met. To assess the credibility of these concerns, we employed a video vignette approach depicting a family of three adult children discussing whether or not to reveal a cancer diagnosis to their mother. Semistructured interviews with 72 oncology patients and 60 of their caregivers were conducted afterwards to explore the views of the participants on the different positions taken by the children. Collusion, family-centric decision making, adulteration of information provided to patients, and circumnavigation of patient involvement appear to be context-dependent. Patients and families alike believe that patients should be told of their conditions. However, the incidence of collusion and familial determination increases with determinations of a poor prognosis, a poor anticipated response to chemotherapy, and a poor premorbid health status. Financial considerations with respect to care determinations remain secondary considerations. Our data suggest that ACPs can be effectively constructed in family-centric societies so long as healthcare professionals continue to update and educate families on the patient's situation. Collusion and familial intervention in the decision-making process are part of efforts to protect the patient from distress and are neither solely dependent on

    Uninhibited access to the unstructured information distributed across the web and in scientific literature databases continues to be beyond the reach of scientists and health professionals. To address this challenge we have developed a literature driven, ontology-centric navigation infrastructure consisting of a content acquisition engine, a domain-specific ontology (in OWL-DL) and an ontology instantiation pipeline delivering sentences derived by domain-specific text mining. A visual query tool for reasoning over A-box instances in the populated ontology is presented and used to build conceptual queries that can be issued to the knowledgebase. We have deployed this generic infrastructure to facilitate data integration and knowledge sharing in the domain of dengue, which is one of the most prevalent viral diseases that continue to infect millions of people in the tropical and subtropical regions annually. Using our unique methodology we illustrate simplified search and discovery on dengue information derived from distributed resources and aggregated according to dengue ontology. Furthermore we apply data mining to the instantiated ontology to elucidate trends in the mentions of dengue serotypes in scientific abstracts since 1974.

    Jongdeog Lee

    2018-01-01

    Full Text Available The paper introduces a new direction in quality-of-service-aware networked sensing that designs communication protocols and scheduling policies for data delivery that are optimized specifically for decision needs. The work complements present decision monitoring and support tools and falls in the larger framework of decision-driven resource management. A hallmark of the new protocols is that they are aware of the inference structure used to arrive at decisions (from logical predicates, as well as the data (and data quality that need to be furnished to successfully evaluate the unknowns on which these decisions are based. Such protocols can therefore anticipate and deliver precisely the right data, at the right level of quality, from the right sources, at the right time, to enable valid and timely decisions at minimum cost to the underlying network. This paper presents the decision model used and the protocol design philosophy, reviews the key recent results and describes a novel system, called Athena, that is the first to embody the aforementioned data delivery paradigm. Evaluation results are presented that compare the performance of decision-centric anticipatory information delivery to several baselines, demonstrating its various advantages in terms of decision timeliness, validity and network resources used. The paper concludes with a discussion of remaining future challenges in this emerging area.

    Corporate, government and military bodies focus significant resources to develop sophisticated and capable information-based systems. The concept of people and resources connected by a robust network capable of extremely high rates of information exchange is very attractive because it allows smaller groups to coordinate together and focus effects from geographically diverse locations. However, there is also a hidden danger that comes with such advanced technology. For example, in the case of the U.S. Military, clearly United States holds a technological advantage over our adversaries and that this advantage is still expanding. This technology gap has resulted in the emergence of potent asymmetrical warfare. All too often in science fiction movies, we see a small group of humans defeat a technologically superior alien race by striking at a hidden weakness that renders all of their advanced weapons as useless, as a result of pervasive connectivity and interdependence. The analogy holds for any large network-centric enterprise, corporate or governmental. This paper focuses on specific technologies and methods that preempt this Achilles Heal scenario.

  13. An Energy Centric Cluster-Based Routing Protocol for Wireless Sensor Networks.

    Hosen, A S M Sanwar; Cho, Gi Hwan

    2018-05-11

    Clustering is an effective way to prolong the lifetime of a wireless sensor network (WSN). The common approach is to elect cluster heads to take routing and controlling duty, and to periodically rotate each cluster head's role to distribute energy consumption among nodes. However, a significant amount of energy dissipates due to control messages overhead, which results in a shorter network lifetime. This paper proposes an energy-centric cluster-based routing mechanism in WSNs. To begin with, cluster heads are elected based on the higher ranks of the nodes. The rank is defined by residual energy and average distance from the member nodes. With the role of data aggregation and data forwarding, a cluster head acts as a caretaker for cluster-head election in the next round, where the ranks' information are piggybacked along with the local data sending during intra-cluster communication. This reduces the number of control messages for the cluster-head election as well as the cluster formation in detail. Simulation results show that our proposed protocol saves the energy consumption among nodes and achieves a significant improvement in the network lifetime.

    Rich Internet Applications (RIAs) are an emerging software platform that blurs the line between web service and native application, and is a powerful tool for handheld device deployment. By democratizing health data management and widening its availability, this software platform has the potential to revolutionize telemedicine, clinical practice, medical education and information distribution, particularly in rural areas, and to make patient-centric medical computing a reality. In this paper, we propose a telemedicine application that leverages the ability of a mobile RIA platform to transcode, organise and present textual and multimedia data, which are sourced from medical database software. We adopted a web-based approach to communicate, in real-time, with an established hospital information system via a custom RIA. The proposed solution allows communication between handheld devices and a hospital information system for media streaming with support for real-time encryption, on any RIA enabled platform. We demonstrate our prototype's ability to securely and rapidly access, without installation requirements, medical data ranging from simple textual records to multi-slice PET-CT images and maximum intensity (MIP) projections.

  15. Data-Centric Situational Awareness and Management in Intelligent Power Systems

    Science.gov (United States)

    Dai, Xiaoxiao

    The rapid development of technology and society has made the current power system a much more complicated system than ever. The request for big data based situation awareness and management becomes urgent today. In this dissertation, to respond to the grand challenge, two data-centric power system situation awareness and management approaches are proposed to address the security problems in the transmission/distribution grids and social benefits augmentation problem at the distribution-customer lever, respectively. To address the security problem in the transmission/distribution grids utilizing big data, the first approach provides a fault analysis solution based on characterization and analytics of the synchrophasor measurements. Specically, the optimal synchrophasor measurement devices selection algorithm (OSMDSA) and matching pursuit decomposition (MPD) based spatial-temporal synchrophasor data characterization method was developed to reduce data volume while preserving comprehensive information for the big data analyses. And the weighted Granger causality (WGC) method was investigated to conduct fault impact causal analysis during system disturbance for fault localization. Numerical results and comparison with other methods demonstrate the effectiveness and robustness of this analytic approach. As more social effects are becoming important considerations in power system management, the goal of situation awareness should be expanded to also include achievements in social benefits. The second approach investigates the concept and application of social energy upon the University of Denver campus grid to provide management improvement solutions for optimizing social cost. Social element--human working productivity cost, and economic element--electricity consumption cost, are both considered in the evaluation of overall social cost. Moreover, power system simulation, numerical experiments for smart building modeling, distribution level real-time pricing and social

    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.

    Kaplan, Robert M; Babad, Yair M

    2011-04-19

    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. 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. 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 improved transparency of all aspects of medical decision

    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.

  3. Restoring Agency to the Human Actor.

    Swann, William B; Jetten, Jolanda

    2017-05-01

    A cursory read of the social psychological literature suggests that when people find themselves in strong situations, they fail to display agency. The early classic studies of conformity, obedience, and bystander intervention, for example, are renowned for showing that when challenged by strong situational pressures, participants acquiesced-even if it meant abandoning their moral principles or disregarding their own sensory data. Later studies of learned helplessness, ego depletion, and stereotype threat echoed this "power of the situation" theme, demonstrating that exposure to (or the expectation of) a frustrating or unpleasant experience suppressed subsequent efforts to actualize goals and abilities. Although this work has provided many valuable insights into the influence of situational pressures, it has been used to buttress an unbalanced and misleading portrait of human agency. This portrait fails to recognize that situations are not invariably enemies of agency. Instead, strong situational forces often allow for, and may even encourage, expressions of human agency. We examine the nature, causes, and consequences of this phenomenon. We endorse a broader approach that emphasizes how responding to situational pressure can coexist with agency. This new emphasis should create greater convergence between social psychological models and the experience of agency in everyday life.

  4. Europe’s fragmented approach towards cyber security

    Directory of Open Access Journals (Sweden)

    Karine e Silva

    2013-10-01

    Full Text Available The article proposes a deeper insight into the variety of concepts used to describe the term cyber security and the ways in which it has been used in recent years. It examines the role of three important actors involved in the internet governance arena, namely governments, private sector and civil society, and how they have influenced the debate. To this end, this paper analyses how different organisations, industry and societal actors see cyber security and how their interests influence the way the debate has evolved. The difficult balance between security and fundamental rights, although not new to governments and society, is of great importance for the internet. Citizens have engaged in favour of an open internet. However, little attention has been paid to the demands of citizens and how they may contribute to a concept of cyber security that brings society to its core. The paper states that for cyberspace to be open and supportive of innovation, the practice of cyber security needs to internalise the interests and perspectives of end users. A multistakeholder approach to cyber security asks a more participative environment where the rules of the game are decided with public participation and consultation, giving citizens the means and methods to influence the way cyber security is conceived and implemented. The paper concludes that although a citizen centric approach towards cyber security should be the way forward, this seems to be yet far from being included in the governmental agenda. The methodology applied in the paper was mainly focused on desk research.

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

    International Nuclear Information System (INIS)

    Jaglin, Sylvy

    2017-01-01

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

    Internet-based search engines have become a significant component of medical practice. Physicians increasingly rely on information available from search engines as a means to improve patient care, provide better education, and enhance research. Specialized search engines have emerged to more efficiently meet the needs of physicians. Details about the ways in which radiologists utilize search engines have not been documented. The authors categorized every 25th search query in a radiology-centric vertical search engine by radiologic subspecialty, imaging modality, geographic location of access, time of day, use of abbreviations, misspellings, and search language. Musculoskeletal and neurologic imagings were the most frequently searched subspecialties. The least frequently searched were breast imaging, pediatric imaging, and nuclear medicine. Magnetic resonance imaging and computed tomography were the most frequently searched modalities. A majority of searches were initiated in North America, but all continents were represented. Searches occurred 24 h/day in converted local times, with a majority occurring during the normal business day. Misspellings and abbreviations were common. Almost all searches were performed in English. Search engine utilization trends are likely to mirror trends in diagnostic imaging in the region from which searches originate. Internet searching appears to function as a real-time clinical decision-making tool, a research tool, and an educational resource. A more thorough understanding of search utilization patterns can be obtained by analyzing phrases as actually entered as well as the geographic location and time of origination. This knowledge may contribute to the development of more efficient and personalized search engines.

    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

  17. 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

    2007-06-15

    This thesis aims to appraise the relevance of using an hybrid top-down / bottom-up approach to evaluate mining projects in the perspective of sustainable development. With the advent of corporate social responsibility and sustainable development concepts, new social expectations have appeared towards companies that go beyond a sole requirement of profit earning capacity. If companies do not answer to these expectations, they risk to lose their social legitimacy. Traditionally associated with social, environmental, economical and political impacts and risks, mining activity is particularly concerned by these new issues. Whereas mineral resources needs have never been so high, mining companies are now expected to limit their negative effects and to take into account their different audiences' expectations in order to define, together, the terms of their social license to operate. Considering the diversity of issues, scales, actors and contexts, the challenge is real and necessitates tools to better understand issues and to structure dialogues. Based on the Uranium mines of Arlit (Niger) case study, this work shows that associating participatory approaches to structuration tools and literature propositions, appears as an efficient formula to better organize issues diversity and to build a structured dialogue between mining companies and their stakeholders. First Part aims to present the theoretical, institutional and sectorial contexts of the thesis. Second Part exposes work and results of the evaluation carried out in Niger. And, Third Part, shows the conclusions that can be derived from this work and presents a proposal for an evaluation framework, potentially applicable to other mining sites. (author)

    To evaluate and compare the centric relation and horizontal condylar guidance using interocclusal wax and extra oral Gothic arch methods and subjective evaluation of dentures thus fabricated. Centric relation and horizontal condylar guidance was recorded by using interocclusal wax and gothic arch tracing in 28 completely edentulous patients. These records were transferred to the articulator and difference in both values was recorded. After that patients were divided in two groups according to the centric relation and horizontal condylar guidance recording method used to achieve balanced occlusion. Response of the dentures was subjectively evaluated using "Woelfel subjective evaluation criteria". Centric relation recorded by both the methods did coincide in 7.14 % of patients. Centric relation recorded by interocclusal wax was posterior to Gothic centric relation in 21.43 % of patients, and anterior to Gothic centric relation in 71.42 % patients. Gothic arch tracings gave higher mean guidance values on both the sides as compared to protrusive wax record in all the subjects, although the difference was statistically insignificant (P > 0.05). Subjective evaluation showed statistical insignificance for all the parameters in both groups. Gothic arch method records the centric relation at a more posterior position than the Static method, but it does not make any difference in clinical performance of the complete denture. Horizontal condylar guidance angle was approximately similar by both the methods.

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

    Directory of Open Access Journals (Sweden)

    Luisa E. Delgado

    2009-06-01

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

    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.

The author suggests that the importance of global civil society as a «third way» between the State and the Free Market is especially high at the time of modern economic crisis. Global civil society organizations work out the new socio-political agenda for the world and new approaches to the global problems. This shaping society is full of conflicts and contradictions but its rapid development in the 1990-2000th is the milestone for developing of truly global politics.

  3. Distribution-centric 3-parameter thermodynamic models of partition gas chromatography.

    2017-03-31

    If both parameters (the entropy, ΔS, and the enthalpy, ΔH) of the classic van't Hoff model of dependence of distribution coefficients (K) of analytes on temperature (T) are treated as the temperature-independent constants then the accuracy of the model is known to be insufficient for the needed accuracy of retention time prediction. A more accurate 3-parameter Clarke-Glew model offers a way to treat ΔS and ΔH as functions, ΔS(T) and ΔH(T), of T. A known T-centric construction of these functions is based on relating them to the reference values (ΔS ref and ΔH ref ) corresponding to a predetermined reference temperature (T ref ). Choosing a single T ref for all analytes in a complex sample or in a large database might lead to practically irrelevant values of ΔS ref and ΔH ref for those analytes that have too small or too large retention factors at T ref . Breaking all analytes in several subsets each with its own T ref leads to discontinuities in the analyte parameters. These problems are avoided in the K-centric modeling where ΔS(T) and ΔS(T) and other analyte parameters are described in relation to their values corresponding to a predetermined reference distribution coefficient (K Ref ) - the same for all analytes. In this report, the mathematics of the K-centric modeling are described and the properties of several types of K-centric parameters are discussed. It has been shown that the earlier introduced characteristic parameters of the analyte-column interaction (the characteristic temperature, T char , and the characteristic thermal constant, θ char ) are a special chromatographically convenient case of the K-centric parameters. Transformations of T-centric parameters into K-centric ones and vice-versa as well as the transformations of one set of K-centric parameters into another set and vice-versa are described.

    2011-04-01

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

    Full Text Available 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

  7. Citizen-Centric Urban Planning through Extracting Emotion Information from Twitter in an Interdisciplinary Space-Time-Linguistics Algorithm

    2016-07-01

    Full Text Available Traditional urban planning processes typically happen in offices and behind desks. Modern types of civic participation can enhance those processes by acquiring citizens’ ideas and feedback in participatory sensing approaches like “People as Sensors”. As such, citizen-centric planning can be achieved by analysing Volunteered Geographic Information (VGI data such as Twitter tweets and posts from other social media channels. These user-generated data comprise several information dimensions, such as spatial and temporal information, and textual content. However, in previous research, these dimensions were generally examined separately in single-disciplinary approaches, which does not allow for holistic conclusions in urban planning. This paper introduces TwEmLab, an interdisciplinary approach towards extracting citizens’ emotions in different locations within a city. More concretely, we analyse tweets in three dimensions (space, time, and linguistics, based on similarities between each pair of tweets as defined by a specific set of functional relationships in each dimension. We use a graph-based semi-supervised learning algorithm to classify the data into discrete emotions (happiness, sadness, fear, anger/disgust, none. Our proposed solution allows tweets to be classified into emotion classes in a multi-parametric approach. Additionally, we created a manually annotated gold standard that can be used to evaluate TwEmLab’s performance. Our experimental results show that we are able to identify tweets carrying emotions and that our approach bears extensive potential to reveal new insights into citizens’ perceptions of the city.

  8. Actor proliferation and the fragmentation of violent groups in conflict

    Directory of Open Access Journals (Sweden)

    Caitriona Dowd

    2015-09-01

    Full Text Available This paper proposes a novel application of a measure of actor fragmentation drawn from electoral studies to the growing field of conflict event data. The application facilitates comparison of conflict environments over time and across cases, while enabling researchers to take account of the relative activity levels of diverse actors. Analysis of the measure suggests that a fragmentation index diverges from a simple count of active conflict agents in important instances, including in providing a more accurate measure of dominant and weaker conflict agents, capturing dynamics of escalation and continuation of conflict over time and across country cases, and reflecting the coalescence of conflict agents around dominant conflict cleavages. The findings suggest that future research may benefit from combining measures of the discrete count of groups and their relative activity levels in order to accurately capture evolving conflict dynamics.

    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.

    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)

  11. 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.

    In biomechanics studies, researchers collect, via experiments or simulations, datasets with hundreds or thousands of trials, each describing the same type of motion (e.g., a neck flexion-extension exercise) but under different conditions (e.g., different patients, different disease states, pre- and post-treatment). Analyzing similarities and differences across all of the trials in these collections is a major challenge. Visualizing a single trial at a time does not work, and the typical alternative of juxtaposing multiple trials in a single visual display leads to complex, difficult-to-interpret visualizations. We address this problem via a new strategy that organizes the analysis around motion trends rather than trials. This new strategy matches the cognitive approach that scientists would like to take when analyzing motion collections. We introduce several technical innovations making trend-centric motion visualization possible. First, an algorithm detects a motion collection's trends via time-dependent clustering. Second, a 2D graphical technique visualizes how trials leave and join trends. Third, a 3D graphical technique, using a median 3D motion plus a visual variance indicator, visualizes the biomechanics of the set of trials within each trend. These innovations are combined to create an interactive exploratory visualization tool, which we designed through an iterative process in collaboration with both domain scientists and a traditionally-trained graphic designer. We report on insights generated during this design process and demonstrate the tool's effectiveness via a validation study with synthetic data and feedback from expert musculoskeletal biomechanics researchers who used the tool to analyze the effects of disc degeneration on human spinal kinematics.

  19. Classification of Beta-lactamases and penicillin binding proteins using ligand-centric network models.

    Directory of Open Access Journals (Sweden)

    Hakime Öztürk

    Full Text Available β-lactamase mediated antibiotic resistance is an important health issue and the discovery of new β-lactam type antibiotics or β-lactamase inhibitors is an area of intense research. Today, there are about a thousand β-lactamases due to the evolutionary pressure exerted by these ligands. While β-lactamases hydrolyse the β-lactam ring of antibiotics, rendering them ineffective, Penicillin-Binding Proteins (PBPs, which share high structural similarity with β-lactamases, also confer antibiotic resistance to their host organism by acquiring mutations that allow them to continue their participation in cell wall biosynthesis. In this paper, we propose a novel approach to include ligand sharing information for classifying and clustering β-lactamases and PBPs in an effort to elucidate the ligand induced evolution of these β-lactam binding proteins. We first present a detailed summary of the β-lactamase and PBP families in the Protein Data Bank, as well as the compounds they bind to. Then, we build two different types of networks in which the proteins are represented as nodes, and two proteins are connected by an edge with a weight that depends on the number of shared identical or similar ligands. These models are analyzed under three different edge weight settings, namely unweighted, weighted, and normalized weighted. A detailed comparison of these six networks showed that the use of ligand sharing information to cluster proteins resulted in modules comprising proteins with not only sequence similarity but also functional similarity. Consideration of ligand similarity highlighted some interactions that were not detected in the identical ligand network. Analysing the β-lactamases and PBPs using ligand-centric network models enabled the identification of novel relationships, suggesting that these models can be used to examine other protein families to obtain information on their ligand induced evolutionary paths.

  20. 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.

    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

  2. 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.

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

    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.

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

    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.

  5. Biomass markets. Growth strategy and challenges for French actors

    International Nuclear Information System (INIS)

    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

    2015-01-01

    We propose a novel approach to theorizing hybridity in public and nonprofit organizations. The concept of hybridity is widely used to describe organizational responses to changes in governance, but the literature seldom explains how hybrids arise or what forms they take. Transaction cost and organizational design literatures offer some solutions, but lack a theory of agency. We use the institutional logics approach to theorize hybrids as entities that face a plurality of normative frames. Logics provide symbolic and material elements that structure organizational legitimacy and actor identities. Contradictions between institutional logics offer space for them to be elaborated and creatively reconstructed by situated agents. We propose five types of organizational hybridity – segmented, segregated, assimilated, blended, and blocked. Each type is theoretically derived from empirically observed variations in organizational responses to institutional plurality. We develop propositions to show how our approach to hybridity adds value to academic and policy-maker audiences. PMID:26640298

    2008-01-01

    Nuclear and high-energy physicists routinely execute data processing and data analysis jobs on a Grid and need to be able to easily and remotely monitor the execution of these jobs. Existing Grid monitoring tools provide abundant information about the whole system, but are geared towards production jobs and well suited for Grid administrators, while the information tailored towards an individual user is not readily available in a user-friendly and user-centric way. Such User Centric information includes monitoring information such as the status of the submitted job, queue position, time of the start/finish, percentage of being done, error messages, standard output, and reasons for failure. We proposed to develop a framework based on Grid service technology that allows scientists to track and monitor their jobs easily from a user-centric view. The proposed framework aims to be flexible so that it can be applied by any Grid Virtual Organization (VO) with various ways of collecting the user-centric job monitoring information built into the framework. Furthermore, the framework provides a rich and reusable set of methods of presenting the information to the user from within a Web browser and other clients. In this presentation, we will give an architectural overview of the UCM service, show an example implementation in the RHIC/STAR experiment context and discuss limitations and future collaborative work

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

    Directory of Open Access Journals (Sweden)

    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.

    Full Text Available In the era of after reformation, Indonesia has developed rapidly enough in political sector and mass media freedom. In the local level such as in Bangli Regency, Bali Province, the fight among political actors on the printed mass media took place when the general election to vote for the regent was held. The general election which was held to vote for the regent was full of dynamism in which the candidates fought against one another on the longer mass media. The problems of the present study are as follows: (1 what was the fight among political actors on the printed media when the general election was held to vote the regent of Bangli Regency in 2010 like?; (2 the factors leading to it?; and (3 what was the impact and meaning of the fight among the political actors on the printed media? The theories used in the present study were the theory of discourse of relation of knowledge and power, the theory of the impact of media such as the agenda setting, the theory of framing, the theory of media text analysis, the theory of hegemony, and the theory of capital. The research method used was the qualitative approach with critical paradigm.  The forms of the fight among political actors took place in the arenas of news articles, advertorials, advertisements, and paid articles. The fight taking place in these arenas started from the fight for the self-image of the actors to the political issue. The factors leading to it was political factor, economic factor, and mass media. The fight among the political actors affected political sector, economic sector, and cultural sector. The fight among the political actors on the printed media contained pragmatic meaning of the media and political actors, the image, popular life style, and change of political culture in Bangli.

    Afifi, Mahmoud; Hussain, Khaled F.; Ibrahim, Hosny M.; Omar, Nagwa M.

    2015-06-01

    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.

    This thesis aims to appraise the relevance of using an hybrid top-down / bottom-up approach to evaluate mining projects in the perspective of sustainable development. With the advent of corporate social responsibility and sustainable development concepts, new social expectations have appeared towards companies that go beyond a sole requirement of profit earning capacity. If companies do not answer to these expectations, they risk to lose their social legitimacy. Traditionally associated with social, environmental, economical and political impacts and risks, mining activity is particularly concerned by these new issues. Whereas mineral resources needs have never been so high, mining companies are now expected to limit their negative effects and to take into account their different audiences' expectations in order to define, together, the terms of their social license to operate. Considering the diversity of issues, scales, actors and contexts, the challenge is real and necessitates tools to better understand issues and to structure dialogues. Based on the Uranium mines of Arlit (Niger) case study, this work shows that associating participatory approaches to structuration tools and literature propositions, appears as an efficient formula to better organize issues diversity and to build a structured dialogue between mining companies and their stakeholders. First Part aims to present the theoretical, institutional and sectorial contexts of the thesis. Second Part exposes work and results of the evaluation carried out in Niger. And, Third Part, shows the conclusions that can be derived from this work and presents a proposal for an evaluation framework, potentially applicable to other mining sites. (author)

    Despite significant advancements in the scientific evidence base of interventions to improve newborn survival, we have not yet been able to "bend the curve" to markedly accelerate global rates of reduction in newborn mortality. The ever-widening gap between discovery of scientific best practices and their mass adoption by families (the evidence-practice gap) is not just a matter of improving the coverage of health worker-community interactions. The design of the interactions themselves must be guided by sound behavioral science approaches such that they lead to mass adoption and impact at a large scale. The main barrier to the application of scientific approaches to behavior change is our inability to "unbox" the "black box" of family health behaviors in community settings. The authors argue that these are not black boxes, but in fact thoughtfully designed community systems that have been designed and upheld, and have evolved over many years keeping in mind a certain worldview and a common social purpose. An empathetic understanding of these community systems allows us to deconstruct the causal pathways of existing behaviors, and re-engineer them to achieve desired outcomes. One of the key reasons for the failure of interactions to translate into behavior change is our failure to recognize that the content, context, and process of interactions need to be designed keeping in mind an organized community system with a very different worldview and beliefs. In order to improve the adoption of scientific best practices by communities, we need to adapt them to their culture by leveraging existing beliefs, practices, people, context, and skills. The authors present a systems approach for community-centric design of interactions, highlighting key principles for achieving intrinsically motivated, sustained change in social norms and family health behaviors, elucidated with progressive theories from systems thinking, management sciences, cross-cultural psychology, learning

  11. [Can we consider the journalist an actor in suicide prevention?

    2016-10-01

    After more than 50 years of dedicated research, media coverage of suicide is now well known to have a significant influence on the suicide epidemiology. This influence is supposed to result from two opposite effects. The Werther effect (WE) refers to the robust increase of suicide rates following the publication of a suicide story. This specific kind of mass cluster implies a suggestion process, i.e. imitation of the depicted death by vulnerable persons. In contract, the preventive potential of medias has been labeled the "Papageno effect" (PE). Although more recently discovered and far less known, PE predicts that journalists can help prevent suicidal behaviors beyond a simple WE reduction. Because PE and WE directly bridge journalistic productions to suicidal events, several national and international health organisms (including the World Health Organization) started to see the media as new prevention opportunities. In this paper, we intend to assess the extent to which journalists can be considered as public health actors in the specific field of suicide prevention. Based on a critical review of the so-called Media effect studies, we explore the opportunities, limits and constraints of collaborating with media professionals for public health actions. For that purpose, we focus on the main strategy employed so far, namely providing recommendations for more cautious coverage of suicide. An overview of the efficacy of these recommendations serves not only as a starting point for understanding how public health and journalistic perspectives can confront, but also how they can be combined in a fertile way. Numerous suicide prevention organisms developed strategies in order to assist journalists in reporting suicide stories in a safer way. As a formal support to these strategies, around 30 national or international guides have been produced around the word, with the shared aim of reducing WE and, eventually, promoting PE. The recommendations about articles' style

    To review the potential contribution of Information and Communication Technology (ICT) to enable patient-centric and coordinated care, and in particular to explore the role of patient portals as a developing ICT tool, to assess the available evidence, and to describe the evaluation challenges. Reviews of IMIA, EFMI, and other initiatives, together with literature reviews. We present the progression from care coordination to care integration, and from patient-centric to person-centric approaches. We describe the different roles of ICT as an enabler of the effective presentation of information as and when needed. We focus on the patient's role as a co-producer of health as well as the focus and purpose of care. We discuss the need for changing organisational processes as well as the current mixed evidence regarding patient portals as a logical tool, and the reasons for this dichotomy, together with the evaluation principles supported by theoretical frameworks so as to yield robust evidence. There is expressed commitment to coordinated care and to putting the patient in the centre. However to achieve this, new interactive patient portals will be needed to enable peer communication by all stakeholders including patients and professionals. Few portals capable of this exist to date. The evaluation of these portals as enablers of system change, rather than as simple windows into electronic records, is at an early stage and novel evaluation approaches are needed.

    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

  14. Ethics in actor networks, or: what Latour could learn from Darwin and Dewey.

    2014-03-01

    In contemporary Science, Technology and Society (STS) studies, Bruno Latour's Actor Network Theory (ANT) is often used to study how social change arises from interaction between people and technologies. Though Latour's approach is rich in the sense of enabling scholars to appreciate the complexity of many relevant technological, environmental, and social factors in their studies, the approach is poor from an ethical point of view: the doings of things and people are couched in one and the same behaviorist (third person) vocabulary without giving due recognition to the ethical relevance of human intelligence, sympathy and reflection in making responsible choices. This article argues that two other naturalist projects, the non-teleological virtue ethics of Charles Darwin and the pragmatist instrumentalism of John Dewey can enrich ANT-based STS studies, both, in a descriptive and in a normative sense.

    The chapter analyses recent governance in Denmark of the interaction between climate, energy and land use. Governance is seen as inclusion and exclusion of actors and their perspectives in decisions about problems and solutions. Inclusion and exclusion are discussed as decisions about members...... and focus of public commissions. Furthermore, inclusion and exclusion are discussed as an aspect of NGOs’ development of climate plans and the societal role of such plans. The chapter concludes that governance of this field is balancing the interests of established and polluting sectors and the interest...

    Demand in many industrial buying situations, e.g. project purchases or procurement related to virtual organizations, is discontinuous. In situations of discontinuity, networks are often more of an ad hos informational and social nature, as strong activity and resource links are not present....... Furthermore the governance structure of markets characterized by discontinuous business activities is either that of the "socially constructed market" (Skaates, 2000) or that of the (socially constructed) network (Håkansson and Johanson, 1993). Additionally relationships and actor bonds vary substantially...

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

    Full Text Available Communication mediated by mobile devices is one of the most dynamic sectors of the global economy and is transforming different aspects of our lives, including our ways of relating and our cultural production, distribution and consumption models. Media studies should not ignore these transformations. This paper presents the results of a study carried out during 2008 to determine the actors, contents produced and trends of the mobile communication companies in Barcelona. The study outlines an initial map of the situation, proposes a series of analysis categories and lays the foundations for more specific future studies on mCommunication.

    Full Text Available El presente artículo aborda una revisión genealógica de las implicaciones epistemológicas del pensamiento sobre lo social, planteando su articulación a partir de la dicotomía entre actores y sistemas, por una parte, y entre intra-determinación y extra-determinación de los sujetos sociales, por otra. La inclusión de las capacidades cognitivas de los sujetos en la teoría social plantea, además de un debate teórico en torno a la complementariedad individuo/colectividad, un problema epistemológico vinculado a la recursividad observacional. Desde esta perspectiva, el pensamiento de la complejidad aporta una vía conceptual de solución para las paradojas epistemológicas del pensamiento sobre lo social en la forma de una teoría general de la organización compleja capaz de englobar coherentemente al observador, la acción observadora y los fenómenos observados.The present paper poses a genealogical approach to the epistemological debate on social theory, departing from its configuration upon a dichotomy between systems and actors, on one side, and between intra-determination and extra-determination of social subject, on the other side. The insertion of social subject’s cognitive capabilities into the theoretical reflection on social phenomena poses, beyond the conceptual debate on the complementarity between individual and collectivity, a deep epistemological problem related to observational recursiveness. From this point of view, the complexity paradigm offers a theoretical path that allows solving some of the epistemological paradoxes in the Social Sciences. It makes this possible by posing a general theory of organizational phenomena that coherently involves the observer, the action of observing and the observed phenomena

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

    1999-01-01

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

    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 study compares subjective experiences of patients, wearing complete dentures. Two different methods of determining a centric relation were performed: the traditional method using wax occlusal rims and the Gerber method, based on gothic arch tracings. The success rate of establishing a centric relation in both methods was evaluated (rentgenodiagnostics). The influence of the method used to obtain the centric relation on patients' stomatognathic system (condyle centralization, pain) was also evaluated. Better results were achieved in gothic arch tracing method. Before every prosthetic treatment of edentulous patients, a functional analysis of the TMJ is necessary. The lack of centric relation, in a long term adaptation patients, does not lead to TMD symptoms. This trial is registered with NCT03343015.

    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.

    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.

    Full Text Available The 1999 Tampere Summit marked the start of the development of the external dimension of the European Union’s policy of Justice and Home Affairs (JHA. This external dimension has been reflected in the inclusion of JHA in agreements with third countries, and particularly with Mediterranean countries. Furthermore, the European NeighbourhoodPolicy (ENP, in addition to bilateral and multilateral programmes, confirmed the transformation of the JHA policy into one of the EU’s foreign policy objectives. In the light of this evolution, this article examines Spain’s role in the development of the Mediterraneandimension of the JHA policy: firstly, it covers the stance of José Luis Rodríguez Zapatero’s government toward the JHA policy and its external dimension; secondly, it explores the new parameters of governance in the area of security and the Spanish case through three main factors: the neighbours, spaces and actors that define this governance. Lastly, and within a context of a multiplicity of governance actors on security, it focuses on the Canary Islands,which have acquired a central importance with respect to the management of borders and the policy of development for Africa. The analysis of this period helps to explain the new security perceptions that define Spain’s policy in the Mediterranean.

    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.

    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.

    Zoonotic diseases, transmitted from animals to humans, are a public health challenge in developing countries. Livestock value chain actors have an important role to play as the first line of defence in safeguarding public health. However, although the livelihood and economic impacts of zoonoses are widely known, adoption of biosecurity measures aimed at preventing zoonoses is low, particularly among actors in informal livestock value chains in low and middle-income countries. The main objective of this study was to investigate knowledge of zoonoses and adoption of biosecurity measures by livestock and milk value chain actors in Bura, Tana River County, in Kenya, where cattle, camels, sheep and goats are the main livestock kept. The study utilised a mixed methods approach, with a questionnaire survey administered to 154 value chain actors. Additional information was elicited through key informant interviews and participatory methods with relevant stakeholders outside the value chain. Our results found low levels of knowledge of zoonoses and low levels of adherence to food safety standards, with only 37% of milk traders knowing about brucellosis, in spite of a sero-prevalence of 9% in the small ruminants tested in this study, and no slaughterhouse worker knew about Q fever. Actors had little formal education (between 0 and 10%) and lacked training in food safety and biosecurity measures. Adoption of biosecurity measures by value chain actors was very low or non-existent, with only 11% of butchers wearing gloves. There was a gendered dimension, evidenced by markedly different participation in value chains and lower adoption rates and knowledge levels among female actors. Finally, cultural and religious practices were shown to play an important role in exposure and transmission of diseases, influencing perceptions and attitudes to risks and adoption of biosecurity measures.

    Applied data-centric social sciences aim to develop both methodology and practical applications of various fields of social sciences and businesses with rich data. Specifically, in the social sciences, a vast amount of data on human activities may be useful for understanding collective human nature. In this book, the author introduces several mathematical techniques for handling a huge volume of data and analysing collective human behaviour. The book is constructed from data-oriented investigation, with mathematical methods and expressions used for dealing with data for several specific problems. The fundamental philosophy underlying the book is that both mathematical and physical concepts are determined by the purposes of data analysis. This philosophy is shown throughout exemplar studies of several fields in socio-economic systems. From a data-centric point of view, the author proposes a concept that may change people’s minds and cause them to start thinking from the basis of data. Several goals underlie ...

    Full Text Available The phenomenon of innovation growing rapidly and having a shorter lifespan is a structural change due to the development of ICT (Information and Communications Technology, diverse investment methods, and reduced pattern of innovation adoption. For ICT companies to survive and maintain their success in this ever-changing environment, they need to succeed in fulfilling both productivity and accuracy of innovation. To sustain their innovative success, ICT companies should consistently maintain the direction of innovation towards consumers. The present study analyzes various cases of ICT companies which succeeded or failed to maintain their prior innovative success, and suggests consumer-centric innovation as a solution. To create consumer-centric innovations, companies have to (1 predict the dynamically evolving demand of consumers and continuously transform; (2 proactively employ observation method and big data analysis to discover hidden demands; and (3 identify hassles such as wastes, inconveniences, and anxieties, and put effort in solving these hassles.

    2016-01-01

    Full Text Available We propose a hierarchical brokering architecture (HiBA and Mobile Multicloud Networking (MMCN feedback control framework for mobile device-centric cloud (MDC2 computing. Exploiting the MMCN framework and RESTful web-based interconnection, each tier broker probes resource state of its federation for control and management. Real-time and seamless services were developed. Case studies including intrafederation energy-aware balancing based on fuzzy feedback control and higher tier load balancing are further demonstrated to show how HiBA with MMCN relieves the embedding of algorithms when developing services. Theoretical performance model and real-world experiments both show that an MDC2 based on HiBA features better quality in terms of resource availability and network latency if it federates devices with enough resources distributed in lower tier hierarchy. The proposed HiBA realizes a development platform for MDC2 computing which is a feasible solution to User-Centric Networks (UCNs.

    Full Text Available Abstract Background This paper examines the extent to which actors from sectors other than health engaged with the South Australian Health in All Policies (HiAP initiative, determines why they were prepared to do so and explains the mechanisms by which successful engagement happened. This examination applies theories of policy development and implementation. Methods The paper draws on a five year study of the implementation of HiAP comprising document analysis, a log of key events, detailed interviews with 64 policy actors and two surveys of public servants. Results The findings are analysed within an institutional policy analysis framework and examine the extent to which ideas, institutional factors and actor agency influenced the willingness of actors from other sectors to work with Health sector staff under the HiAP initiative. In terms of ideas, there was wide acceptance of the role of social determinants in shaping health and the importance of action to promote health in all government agencies. The institutional environment was initially supportive, but support waned over the course of the study when the economy in South Australia became less buoyant and a health minister less supportive of health promotion took office. The existence of a HiAP Unit was very helpful for gaining support from other sectors. A new Public Health Act offered some promise of institutionalising the HiAP approach and ideas. The analysis concludes that a key factor was the operation of a supportive network of public servants who promoted HiAP, including some who were senior and influential. Conclusions The South Australian case study demonstrates that despite institutional constraints and shifting political support within the health sector, HiAP gained traction in other sectors. The key factors that encouraged the commitment of others sectors to HiAP were the existence of a supportive, knowledgeable policy network, political support, institutionalisation of the

The key factors that encouraged the commitment of others sectors to HiAP were the existence of a supportive, knowledgeable policy network, political support, institutionalisation of the ideas and approach, and balancing of the economic and social goals of

    The concept of continuous-time trajectory representation has brought increased accuracy and efficiency to multi-modal sensor fusion in modern SLAM. However, regardless of these advantages, its offline property caused by the requirement of global batch optimization is critically hindering its relevance for real-time and life-long applications. In this paper, we present a dense map-centric SLAM method based on a continuous-time trajectory to cope with this problem. The proposed system locally f...

    Full Text Available Purpose. The development of the control system for three-phase network is based on intelligent technologies of network-centric control of heterogeneous objects. The introduction of unmanned aerial vehicles for monitoring of three-phase network increases the efficiency of management. Methodology. The case of decomposition of the instantaneous capacities of the fixed and variable components for 3-wire system. The features of power balance for the different modes of its functioning. It should be noted that symmetric sinusoidal mode is balanced and good, but really unbalanced, if the standard reactive power is not zero. To solve the problem of compensation is sufficient knowledge of the total value of the inactive components of full power (value of the inactive power without detail. The creation of a methodology of measurement and assessment will require knowledge of the magnitudes of each inactive component separately, which leads to the development of a unified approach to the measurement and compensation of inactive components of full power and the development of a generalized theory of power. Results. Procedure for the compensation of the current of zero sequence excludes from circuit the source, as the active component of instantaneous power of zero sequence, and a vector due to a current of zero sequence. This procedure is performed without time delay as it does not require integration. Only a 3–wire system with symmetrical voltage eliminates pulsations and symmetrization of the equivalent conductances of the phases of the task. Under asymmetric voltage, the power is different, its analysis requires the creation of a vector mathematical model of the energy processes of asymmetrical modes of 3–phase systems. Originality. The proposed method extends the basis of the vector method for any zero sequence voltages and shows that the various theories of instantaneous power three wired scheme due to the choice of a basis in a two

    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.

    In the field of RNA, the technologies for studying the transcriptome have created a tremendous potential for deciphering the puzzles of the RNA biology. Along with the excitement, the unprecedented volume of RNA related omics data is creating great challenges in bioinformatics analyses. Here, we present the RNA Centric Annotation System (RCAS), an R package, which is designed to ease the process of creating gene-centric annotations and analysis for the genomic regions of interest obtained from various RNA-based omics technologies. The design of RCAS is modular, which enables flexible usage and convenient integration with other bioinformatics workflows. RCAS is an R/Bioconductor package but we also created graphical user interfaces including a Galaxy wrapper and a stand-alone web service. The application of RCAS on published datasets shows that RCAS is not only able to reproduce published findings but also helps generate novel knowledge and hypotheses. The meta-gene profiles, gene-centric annotation, motif analysis and gene-set analysis provided by RCAS provide contextual knowledge which is necessary for understanding the functional aspects of different biological events that involve RNAs. In addition, the array of different interfaces and deployment options adds the convenience of use for different levels of users. RCAS is available at http://bioconductor.org/packages/release/bioc/html/RCAS.html and http://rcas.mdc-berlin.de. © The Author(s) 2017.

  13. Value-centric design architecture based on analysis of space system characteristics

    Xu, Q.; Hollingsworth, P.; Smith, K.

    2018-03-01

    Emerging design concepts such as miniaturisation, modularity, and standardisation, have contributed to the rapid development of small and inexpensive platforms, particularly cubesats. This has been stimulating an upcoming revolution in space design and development, leading satellites into the era of "smaller, faster, and cheaper". However, the current requirement-centric design philosophy, focused on bespoke monolithic systems, along with the associated development and production process does not inherently fit with the innovative modular, standardised, and mass-produced technologies. This paper presents a new categorisation, characterisation, and value-centric design architecture to address this need for both traditional and novel system designs. Based on the categorisation of system configurations, a characterisation of space systems, comprised of duplication, fractionation, and derivation, is proposed to capture the overall system configuration characteristics and promote potential hybrid designs. Complying with the definitions of the system characterisation, mathematical mapping relations between the system characterisation and the system properties are described to establish the mathematical foundation of the proposed value-centric design methodology. To illustrate the methodology, subsystem reliability relationships are therefore analysed to explore potential system configurations in the design space. The results of the applications of system characteristic analysis clearly show that the effects of different configuration characteristics on the system properties can be effectively analysed and evaluated, enabling the optimization of system configurations.

  14. Combining Vertex-centric Graph Processing with SPARQL for Large-scale RDF Data Analytics

    KAUST Repository

    Abdelaziz, Ibrahim

    2017-06-27

    Modern applications, such as drug repositioning, require sophisticated analytics on RDF graphs that combine structural queries with generic graph computations. Existing systems support either declarative SPARQL queries, or generic graph processing, but not both. We bridge the gap by introducing Spartex, a versatile framework for complex RDF analytics. Spartex extends SPARQL to support programs that combine seamlessly generic graph algorithms (e.g., PageRank, Shortest Paths, etc.) with SPARQL queries. Spartex builds on existing vertex-centric graph processing frameworks, such as Graphlab or Pregel. It implements a generic SPARQL operator as a vertex-centric program that interprets SPARQL queries and executes them efficiently using a built-in optimizer. In addition, any graph algorithm implemented in the underlying vertex-centric framework, can be executed in Spartex. We present various scenarios where our framework simplifies significantly the implementation of complex RDF data analytics programs. We demonstrate that Spartex scales to datasets with billions of edges, and show that our core SPARQL engine is at least as fast as the state-of-the-art specialized RDF engines. For complex analytical tasks that combine generic graph processing with SPARQL, Spartex is at least an order of magnitude faster than existing alternatives.

    Full Text Available Recent rapid developments in wireless and mobile IT technologies have led to their application in many real-life areas, such as disasters, home networks, mobile social networks, medical services, industry, schools, and the military. Business/work environments have become wire/wireless, integrated with wireless networks. Although the increase in the use of mobile devices that can use wireless networks increases work efficiency and provides greater convenience, wireless access to networks represents a security threat. Currently, wireless intrusion prevention systems (IPSs are used to prevent wireless security threats. However, these are not an ideal security measure for businesses that utilize mobile devices because they do not take account of temporal-spatial and role information factors. Therefore, in this paper, an efficient and secure mobile-IPS (m-IPS is proposed for businesses utilizing mobile devices in mobile environments for human-centric computing. The m-IPS system incorporates temporal-spatial awareness in human-centric computing with various mobile devices and checks users’ temporal spatial information, profiles, and role information to provide precise access control. And it also can extend application of m-IPS to the Internet of things (IoT, which is one of the important advanced technologies for supporting human-centric computing environment completely, for real ubiquitous field with mobile devices.

    This study summarizes the main French researchs on people living close to nuclear plants and their perception of nuclear risks. The ethnological approach was utilized, consisting in an observer living long periods of time on the site. It shows the existence of a ''psychogeographical'' zone in which people fell concerned by the building of the plant. This event reinforce the existing tensions between the social actors in the field of the site. The plant is seen as a ''big work'' ''eating'' land from agriculture and recreation, mixed with a nuclear thing mysterious and dangerous. Perceptions and rumors are greatly varying depending time and space. These results may be applied to a better siting of the plants [fr

    As a contribution toward the goal of adaptable, intelligent artificial limbs, this work introduces a continuous actor-critic reinforcement learning method for optimizing the control of multi-function myoelectric devices. Using a simulated upper-arm robotic prosthesis, we demonstrate how it is possible to derive successful limb controllers from myoelectric data using only a sparse human-delivered training signal, without requiring detailed knowledge about the task domain. This reinforcement-based machine learning framework is well suited for use by both patients and clinical staff, and may be easily adapted to different application domains and the needs of individual amputees. To our knowledge, this is the first my-oelectric control approach that facilitates the online learning of new amputee-specific motions based only on a one-dimensional (scalar) feedback signal provided by the user of the prosthesis. © 2011 IEEE

    In the German movie "Vincent will Meer" a healthy actor portrays a man with Tourette's syndrome. Objective. The aim of this study was to investigate whether the performance of tics is convincing and whether this judgment depends on whether he/she suffers from tics or not. While the movie was broadcasted in German cinemas, we put an online survey (including 28 questions on different aspects related to the observation, performance, and authenticity of tics) on the web pages of the German self-help group. 276/296 surveys submitted could be used for further analyses. 95.7% of all participants felt that the performance of tics was convincing. However, people with tics (n = 26) were less convinced compared to those who had never met a person with tics (n = 110) (P = 0.020). Our results further support the hypothesis that tics are not "abnormal" but "physiological" movements that are only misplaced both in time and context.

    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

    Full Text Available Este artículo presenta una descripción del funcionamiento de la disciplina escolar en una institución educativa de secundaria en Colombia. Tiene como objetivo explicar el origen del conflicto disciplinario, las situaciones que lo generan, la forma como la institución trata de lograr y mantener la disciplina, las explicaciones que cada uno de los actores da a las situaciones conflictivas y la manera como son vividas por ellos. El diseño metodológico de la investigación combinó una encuesta, entrevistas y el análisis de documentos de la institución educativa. El análisis de los datos se hace a la luz de planteamientos sociológicos que reconocen la enorme importancia que ejercen las estructuras sociales sobre la forma de pensar y actuar de los individuos, pero también resaltan la gran capacidad de los actores sociales para amoldarse a dichas estructuras y a través de sus ideas y acciones darle una dinámica propia al tipo de relaciones que establecen entre individuos en sus entornos de vida más inmediatos. Se pudo concluir que sobre la disciplina escolar no hay unidad de criterio entre los docentes, los directivos y los estudiantes, ni en su definición, ni en su importancia, ni en los medios para conseguirla; dichas diferencias producen tensiones y desacuerdos entre los miembros de la comunidad educativa.

    In Turkey, the discussions in the modern sense about disaster management begun after the 1992 Erzincan and the 1995 Dinar earthquakes, faulting in terms of features and effects. These earthquakes are "Urban Earthquakes'' with effects and faulting charectristics, and have led to radical changes in terms of disaster and disaster management. Disaster Management, to become a science in the world, but with the 1999 Izmit and Duzce earthquakes in Turkey has begun to take seriously on the agenda. Firstly, such as Civil Defense and Red Crescent organizations, by transforming its own, have entered into a new organizing effort. By these earthquakes, NGO's have contributed the search-rescue efforts in the field and to the process of normalization of life. Because "the authority and responsibilities" of NGO's could not be determined, and could not be in planning and scenario studies, we faced the problems. Thus, to the citizens of our country-specific "voluntary" has not benefited enough from the property. The most important development in disaster management in 2009, the Disaster and Emergency Management Presidency (AFAD) has been the establishment. However, in terms of coordination and accreditation to the target point has been reached yet. Another important issue in disaster management (need to be addressed along with disaster actors) is the role of women in disasters. After the Golcuk Earthquake, successful field works of women and women's victimization has attracted attention in two different directions. Gender-sensitive policies should be noted by the all disaster actors due to the importance of the mitigation, and these policies should take place in laws, regulations and planning.

  5. Water-centric nexus for response to climate change on agriculture and forest sector: The case of the Korean Peninsula

    2017-12-01

    Given their complexity and the number of stakeholders involved, it is difficult to solve social issues or problems based on an analysis that focuses on a single dimension. In particular, research surrounding climate change is inherently multidisciplinary and there is a need for highly pluralistic nexuses that can be used as a framework for policy decisions. Here, we suggest to water-centric nexus on agriculture and forest sector to improve response to climate change. The nexus is composed agricultural water demand and forest water supply to enhancing water-related adaptation to climate change in the Korean Peninsula. Agricultural productivity and water use related variables was estimating by EPIC crop model, and InVEST model applied for estimation of forest water supply. Results under two climate change scenarios (RCP4.5 and 8.5) and time period (2050s and 2070s), the forest water supply for the all future climate scenarios will increase significantly. In case of agriculture, irrigated crops experienced only the benefits of climate change, but rainfed crops were negatively impacted. It was also found that crop irrigation demand in the future is expected to be around twice as high as baseline levels, thus making irrigation more difficult to successfully implement. These hydrological threats have the potential to greatly reduce food security. In the nexus perspectives, the drop in the productivity of rainfed crops and the increase in irrigation demand in the agriculture sector can be resolved through interconnections with the forest sector. Appropriate management of the water supply in future climatic conditions characterized by increasing precipitation can maintain and expand agricultural areas through irrigation. To achieve this, a time-series water supply versus demand analysis must be performed so that an accurate balance between supply and demand can be established. Water-centric interactions of the agriculture and forest are the basis of nexus-based adaptation

    Mettler, Tobias; Vimarlund, Vivian

    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 During the attempts for theatrical renewal in the twenties, several playwrights worked also as actors. The Baroja’s acted in the company ‘El Mirlo Blanco’; D. Pío participation was enthusiastic although brief, while his brother Ricardo was better recognized for his work as stage designer. Rivas Cherif participated in numerous performances and his coherence with the new theatre model that he defended was unanimously praised. Eusebio de Gorbea was considered the best actor among the playwrights, although his more appreciated characteristics like tone, gesture and roughness approached him to naturalism. The interpretative work of these authors as components of a group, whose nucleus remained amongst successive renovation attempts, is also recognized by its discipline, renounce to individual success and subordination to scenic treatment.En los ensayos de renovación teatral de los años veinte, varios dramaturgos intervinieron como actores. Los hermanos Baroja actuaron en la compañía ‘El Mirlo Blanco’: la participación de D. Pío fue entusiasta pero breve; de su hermano Ricardo se recuerda con mayor interés su labor de escenógrafo. Las numerosas actuaciones de Rivas Cherif fueron unánimemente valoradas por su coherencia con los presupuestos del nuevo teatro que tanto defendió. Eusebio de Gorbea fue el dramaturgo más reconocido en su labor de actor, si bien sus rasgos más destacados, tono, ademán, rudeza le sitúan cercano al naturalismo. La labor interpretativa de estos autores como componentes de un grupo, cuyo núcleo se mantiene en los sucesivos intentos renovadores, es también alabada por su disciplina, renuncia al lucimiento y supeditación al tratamiento escénico.

  12. Confidence, Actors' Beliefs and Transparency: the Case of ANDRA

    Considering the predominant position of nuclear power in France, one could think that nuclear in France has always benefited from a high consensus within the French opinion. The emerging of nuclear and its development through years in France, might seem to have taken place in a rather singular climate of good social acceptability, if compared with other countries. Yet, now that the question has to be raised concerning the management of long-life radioactive waste, things are complicated. A strong contest accompanies each choice of a site that could be dedicated to stocking those very sensitive wastes. Actually, only one site has been found and accepted by local political authorities. A laboratory has been created by ANDRA, with the scope to study the opportunity to stock long-life radioactive waste. The decision should take place in 2006 and, since many years, is at the origin of a strong controversy between actors in favour or against the project. How to explain that? Why in a country where everything has been done for the nuclear development, is it so difficult to find a place to manage the residues of such an activity? It is even amazing to see that, on this specific topic, controversy is even stronger in France than in Sweden, although the Swedish opinion is by far less nuclear-friendly than the French one. The present paper focuses on one aspect of the strategy followed by ANDRA in order to achieve its mission: the essential aspect of the social acceptability of its activities. The comprehension of the difficulties met by ANDRA is not possible without taking into account the history of French nuclear and the catastrophic lack of democracy that characterised it. Among the results from an inquiry done by CREIDD for ANDRA in 2002, it indeed emerged that ANDRA was most of all perceived as an entity belonging to a global 'nuclear sphere'. Although rather young, ANDRA therefore has to carry with it the 'weigh of history' of the whole 'sphere', and its social

    Full Text Available In this article we distinguish the discourses used by the actors involved in terrorist actions (in an active or a passive way that are gathered by the media. Considering discourse as the addition of different arguments which are part of a general narrative, we perform a theoretical approach and an analysis proposal with the aim of identifying the discourses carried out by terrorists and governments. Firstly, we make a brief review of the existent bibliography emphasizing on previous analytical models. Secondly, and as a prologue of our theoretical proposal, we delimit the definitions of mass-mediated terrorism and discursive framework. Finally, and as main topic of the article, we present the general narratives of terrorists and governments respectively. All in all, we tackle terrorists and Institutions by speaking and issuing messages that show the map of institutional forces. En este artículo distinguimos los discursos que utilizan los actores implicados en acciones terroristas (ya sea de manera activa o pasiva y que son recogidos por los medios de comunicación. Valorando como discurso la suma de distintos argumentos que conforman una narrativa general, realizamos una aproximación teórica y una propuesta de análisis con el fin de identificar los discursos de los terroristas y de los gobiernos. En primer lugar realizamos un breve repaso de la bibliografía existente enfatizando en modelos analíticos previos. A continuación, a modo de prólogo para nuestra propuesta teórica, acotamos las definiciones de terrorismo mediatizado y marco discursivo. Para finalizar, y como eje central del artículo, exponemos las narrativas generales de los terroristas y de los gobiernos respectivamente. En resumen, abordamos terroristas e instituciones hablándose, emitiendo mensajes que reflejan el mapa de fuerzas institucionales.

  14. Reinforcement learning using a continuous time actor-critic framework with spiking neurons.

    Full Text Available Animals repeat rewarded behaviors, but the physiological basis of reward-based learning has only been partially elucidated. On one hand, experimental evidence shows that the neuromodulator dopamine carries information about rewards and affects synaptic plasticity. On the other hand, the theory of reinforcement learning provides a framework for reward-based learning. Recent models of reward-modulated spike-timing-dependent plasticity have made first steps towards bridging the gap between the two approaches, but faced two problems. First, reinforcement learning is typically formulated in a discrete framework, ill-adapted to the description of natural situations. Second, biologically plausible models of reward-modulated spike-timing-dependent plasticity require precise calculation of the reward prediction error, yet it remains to be shown how this can be computed by neurons. Here we propose a solution to these problems by extending the continuous temporal difference (TD learning of Doya (2000 to the case of spiking neurons in an actor-critic network operating in continuous time, and with continuous state and action representations. In our model, the critic learns to predict expected future rewards in real time. Its activity, together with actual rewards, conditions the delivery of a neuromodulatory TD signal to itself and to the actor, which is responsible for action choice. In simulations, we show that such an architecture can solve a Morris water-maze-like navigation task, in a number of trials consistent with reported animal performance. We also use our model to solve the acrobot and the cartpole problems, two complex motor control tasks. Our model provides a plausible way of computing reward prediction error in the brain. Moreover, the analytically derived learning rule is consistent with experimental evidence for dopamine-modulated spike-timing-dependent plasticity.

  15. 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.

    In the early times of space industry, the feasibility of Earth observation missions was directly driven by what could be achieved by the satellite. It was clear to everyone that the ground segment would be able to deal with the small amount of data sent by the payload. Over the years, the amounts of data processed by the spacecrafts have been increasing drastically, leading to put more and more constraints on the ground segment performances - and in particular on timeliness. Nowadays, many space systems require high data throughputs and short response times, with information coming from multiple sources and involving complex algorithms. It has become necessary to perform thorough end-to-end analyses of the full system in order to optimise its cost and efficiency, but even sometimes to assess the feasibility of the mission. This paper presents a novel framework developed by Astrium Satellites in order to meet these needs of timeliness evaluation and optimisation. This framework, named ETOS (for “End-to-end Timeliness Optimisation of Space systems”), provides a modelling process with associated tools, models and GUIs. These are integrated thanks to a common data model and suitable adapters, with the aim of building suitable space systems simulators of the full end-to-end chain. A big challenge of such environment is to integrate heterogeneous tools (each one being well-adapted to part of the chain) into a relevant timeliness simulation.

  7. SELF-DETERMINATION AND POWER: A HUMAN-CENTRIC APPROACH TO THE INTERNATIONAL RELATIONS

    Directory of Open Access Journals (Sweden)

    Shameer Modongal

    2017-05-01

    Full Text Available This paper analyzes the importance of self-determination in international relations. It explains the puzzle why some small regions or group of people are ready to be small states by separating from big powerful states. The self-determination of a nation is preferable to the people than a military power of the large state. The military power of a state may not translate into a better life of people. So people’s empowerment cannot be treated the necessary outcome of state’s military power. When one group of people feel as marginalized in national policymaking and its implications, they show a secessionist tendency. This paper contends that people may prefer their ideology, identity and self-determination than the power of the state.

    There are many challenges associated with ontology building, as the process often touches on many different subject areas; it needs knowledge of the problem domain, an understanding of the ontology formalism, software in use and, sometimes, an understanding of the philosophical background. In practice, it is very rare that an ontology can be completed by a single person, as they are unlikely to combine all of these skills. So people with these skills must collaborate. One solution to this is to use face-to-face meetings, but these can be expensive and time-consuming for teams that are not co-located. Remote collaboration is possible, of course, but one difficulty here is that domain specialists use a wide-variety of different "formalisms" to represent and share their data - by the far most common, however, is the "office file" either in the form of a word-processor document or a spreadsheet. Here we describe the development of an ontology of immunological cell types; this was initially developed by domain specialists using an Excel spreadsheet for collaboration. We have transformed this spreadsheet into an ontology using highly-programmatic and pattern-driven ontology development. Critically, the spreadsheet remains part of the source for the ontology; the domain specialists are free to update it, and changes will percolate to the end ontology. We have developed a new ontology describing immunological cell lines built by instantiating ontology design patterns written programmatically, using values from a spreadsheet catalogue. This method employs a spreadsheet that was developed by domain experts. The spreadsheet is unconstrained in its usage and can be freely updated resulting in a new ontology. This provides a general methodology for ontology development using data generated by domain specialists.

    CERN Document Server

    Arbanowski, S; Steglich, S; Popescu-Zeletin, R

    2001-01-01

    A variety of concepts for service integration and corresponding systems have been developed. On one hand, they aim for the interworking and integration of classical telecommunications and data communications services. On the other, they are focusing on universal service access from a variety of end-user systems. Many of the technical problems, resulting from service integration and service personalisation, have been solved. However, all these systems are driven by the concept of providing several technologies to users by keeping the peculiarity of each service. Looking at human communication behaviour and communication space, it is obvious that human beings interact habitually in a set of contexts with their environment. The individual information preferences and needs, persons to interact with, and the set of devices controlled by each individual define their personal communication space. Following this view, a new approach is to build communication systems not on the basis of specific technologies, but on t...

    Full Text Available Background. In the German movie “Vincent will Meer” a healthy actor portrays a man with Tourette’s syndrome. Objective. The aim of this study was to investigate whether the performance of tics is convincing and whether this judgment depends on whether he/she suffers from tics or not. Methods. While the movie was broadcasted in German cinemas, we put an online survey (including 28 questions on different aspects related to the observation, performance, and authenticity of tics on the web pages of the German self-help group. 276/296 surveys submitted could be used for further analyses. Results. 95.7% of all participants felt that the performance of tics was convincing. However, people with tics (n=26 were less convinced compared to those who had never met a person with tics (n=110 (P=0.020. Conclusions. Our results further support the hypothesis that tics are not “abnormal” but “physiological” movements that are only misplaced both in time and context.

    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.

  15. Application of process monitoring to anomaly detection in nuclear material processing systems via system-centric event interpretation of data from multiple sensors of varying reliability

    2017-01-01

    Highlights: • Process monitoring can strengthen nuclear safeguards and material accountancy. • Assessment is conducted at a system-centric level to improve safeguards effectiveness. • Anomaly detection is improved by integrating process and operation relationships. • Decision making is benefited from using sensor and event sequence information. • Formal framework enables optimization of sensor and data processing resources. - Abstract: In this paper, we apply an advanced safeguards approach and associated methods for process monitoring to a hypothetical nuclear material processing system. The assessment regarding the state of the processing facility is conducted at a system-centric level formulated in a hybrid framework. This utilizes architecture for integrating both time- and event-driven data and analysis for decision making. While the time-driven layers of the proposed architecture encompass more traditional process monitoring methods based on time series data and analysis, the event-driven layers encompass operation monitoring methods based on discrete event data and analysis. By integrating process- and operation-related information and methodologies within a unified framework, the task of anomaly detection is greatly improved. This is because decision-making can benefit from not only known time-series relationships among measured signals but also from known event sequence relationships among generated events. This available knowledge at both time series and discrete event layers can then be effectively used to synthesize observation solutions that optimally balance sensor and data processing requirements. The application of the proposed approach is then implemented on an illustrative monitored system based on pyroprocessing and results are discussed.

    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.

    We have performed an in situ test of the iron limitation hypothesis in the subarctic North Pacific Ocean. A single enrichment of dissolved iron caused a large increase in phytoplankton standing stock and decreases in macronutrients and dissolved carbon dioxide. The dominant phytoplankton species shifted after the iron addition from pennate diatoms to a centric diatom, Chaetoceros debilis, that showed a very high growth rate, 2.6 doublings per day. We conclude that the bioavailability of iron regulates the magnitude of the phytoplankton biomass and the key phytoplankton species that determine the biogeochemical sensitivity to iron supply of high-nitrate, low-chlorophyll waters.

    We propose a centralised platform for quantitative benchmarking of key performance indicators (KPI) among mutually distrustful organisations. Our platform offers users the opportunity to request an ad-hoc benchmarking for a specific KPI within a peer group of their choice. Architecture and protocol are designed to provide anonymity to its users and to hide the sensitive KPI values from other clients and the central server. To this end, we integrate user-centric peer group formation, exchangeable secure multi-party computation protocols, short-lived ephemeral key pairs as pseudonyms, and attribute certificates. We show by empirical evaluation of a prototype that the performance is acceptable for reasonably sized peer groups.

    This document proposes brief presentations (web site address, activities) of actors operating in the hydrogen sector in France. These actors are public actors who can be incentive or financing actors (ADEME, ANR) or research institutions (CNRS, CEA, university and engineering schools, IFP, INERIS, INRETS), private actors like industrial groups (Air Liquide, AREVA, GDF Suez, Total, PSA Peugeot Citroen, Renault, Saint-Gobain, SNECMA, ST Microelectronics, 3M, Veolia Environnement) or small companies (Alca Torda Applications, Axane, CETH2, Helion, MaHytec, N-GHY, PaxiTech, Sertronic, ULLIT). It also presents the HyPAC platform created by the AFH2 and ADEME), the AFH2 (the French Association for Hydrogen), and regional initiatives

    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.

    The authors offer guidance on recognizing and resisting test-centric instruction in reading comprehension. They posit that five practices indicate a test-centric view of comprehension: when the tested content is privileged, when the test becomes the text, when annotation requirements replace strategic thinking, when test items frame how students…

    Full Text Available Resumen: Este artículo propone analizar las dinámicas de movilización de los actores locales que surgen en los territorios de fronteras, considerados como espacios claves de interrelaciones transfronterizas. El análisis moviliza varios casos de fronteras en Centroamérica para centrarse en las asociaciones transfronterizas surgidas de la sociedad civil o de municipios. Examinar las dinámicas fronterizas a través de las estrategias de los actores locales permite proponer un enfoque “desde abajo” de los procesos de cooperación transfronteriza y de integración regional, y captar la afirmación de nuevas categorías de actores, locales como transnacionales, en las reconfiguraciones territoriales. Palabras claves : frontera, transfronterizo, movilización, actores locales  *** Abstract: This article aims to analyze the dynamics of mobilization of local actors that arise in the border territories, which are considered as key areas of cross-border relationships. The analysis is based on several cases of Central America borders and focus especially on cross-border partnerships emerging from the civil society or municipalities. Analyze the border dynamics through those local actors allows to highlight a "bottom up" approach of cross-border cooperation and regional integration processes. It shows that new categories of actors assert oneself, at local and transnational scales, in the territorial transformations affecting border spaces.

  9. Actors or Spectators? Vulnerability and Critical Environmental Law

    Full Text Available The question of whether we as humans should remain spectators of the great theatre of ecological disaster or become actors is a false dichotomy. In this chapter, I argue that both are needed, since the critical distance of spectatorship does not annul the need for immersion in the ecological continuum. A tool in the realisation of this is the concept of vulnerability, which is here conceptualised as a space of ‘the middle’ (as opposed, emphatically, to ‘the centre’ and offers an opportunity to think away from the sterile debate on eco/anthropocentricity and from such limiting hierarchies as animal/human, human/environmental, natural/artificial. This new, vulnerable position of the middle allows the reconfiguration of ecological processes, and more specifically, the position of environmental law in relation to them. Environmental law now finds itself amidst a new, moving, ‘open ecology’ of social, biological and ecological processes. This is a new, radical conceptualisation of what I have called ‘critical environmental law’, based upon an epistemology of observation and an ontology of being part of this open ecology. Environmental law, in this light, is simultaneously reformulated as being an invitation to disciplinary and ontological openness and yet a call to remain immanent within existing legal structures. This finds expression in four critical environmental positions that set the stage for the further elaboration of a critical environmental law. La cuestión de si nosotros, como seres humanos, debemos seguir siendo espectadores del gran teatro de la catástrofe ecológica o convertirnos en actores es una dicotomía falsa. En este artículo se sostiene que ambos son necesarios, ya que la distancia crítica del espectador no anula la necesidad de una inmersión en el continuum ecológico. Una herramienta para la realización de esto es el concepto de vulnerabilidad, que aquí se concibe como un espacio 'intermedio' (en oposici

  10. Natural gas supply strategies for European energy market actors

    Girault, Vincent

    2007-06-01

    The liberalization of the European energy markets leads to the diversification of supplies. Hence, we analyse the natural gas importation problem in a power producer point of view. Upstream and downstream natural gas markets are concentrated. In this oligopoly context, our topic is to focus on strategies which modify natural gas sourcing price. This by studying the surplus sharing on the natural gas chain. A European firm can bundle gas and electricity outputs to increase its market share. Therefore, a bundling strategy of a power producer in competition with a natural gas reseller on the final European energy market increases upstream natural gas price. Bundling also acts as a raising rival cost strategy and reduces the rivals' profit. Profits opportunities incite natural gas producers to enter the final market. Vertical integration between a natural gas producer and a European gas reseller is a way, for producers, to catch end consumer surplus. Vertical integration results in the foreclosure of the power producer on the upstream natural gas market. To be active on the natural gas market, the power producer could supply bundles. But, this strategy reallocates the rent. The integrated firm on natural gas gets the rent of electricity market in expenses of the power producer. Then, a solution for the power producer is to supply gas and electricity as complements. Then, we consider a case where vertical integration is not allowed. Input price discrimination by a monopolist leads to a lower natural gas price for the actor which diversifies its supplying sources. Furthermore, a bundling strategy increases the gap between the price proposed to the firm which also diversify its output and the firm which is fully dependent from the producer to supply natural gas on final market.

    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.

    This study established the concept of data-centric design, which is the latest design technique, by analyzing the existing literature so that the data-centric design would be applied to the nuclear power plant projects in Korea and analyzed the status of data-centric design application by the advanced companies and the domestic design companies participating in the nuclear power plant projects. By analyzing the function of the 3D CAD commercial system and all design drawings used in the nuclear power plant projects in Korea, a data-centric design integrated system model has been developed. This study established the concept of data-centric design technology, analyzed the functions of the plant architect engineering (A/E) software being globally used in the plant field and the design process status of nuclear power plant projects in Korea. A design information integration system building model, which is capable of data-centric design, in the place of the existing document-centric system design such as P and ID and SLD, has been suggested through the investigation on the data-centric design cases of the advanced companies. The major functions of the suggested model required for the application to the domestic industry were drawn. The suggested framework builds the field design, which was performed in the 3D system of the constructor, as an owner's field design system, which can manage all design drawings generated from the field design and the related information in integrated way. An as-built full model integrated of plant architect engineering, supplier design and field design is built. It is handed over to the operation team at the O and M stage and utilized in the maintenance and repair. As a power plant full model of future construction project has been enabled, an improved design process has been suggested, in which only the design change information during the plant architect engineering (A/E) and the design change information during the field design

    Our understanding of the complex interconnected processes performed by microbial communities is hindered by our inability to culture the vast majority of microorganisms. Metagenomics provides a way to bypass this cultivation bottleneck and recent advances in this field now allow us to recover a growing number of genomes representing previously uncultured populations from increasingly complex environments. In this study, a temporal genome-centric metagenomic analysis was performed of lab-scale anaerobic digesters that host complex microbial communities fulfilling a series of interlinked metabolic processes to enable the conversion of cellulose to methane. In total, 101 population genomes that were moderate to near-complete were recovered based primarily on differential coverage binning. These populations span 19 phyla, represent mostly novel species and expand the genomic coverage of several rare phyla. Classification into functional guilds based on their metabolic potential revealed metabolic networks with a high level of functional redundancy as well as niche specialization, and allowed us to identify potential roles such as hydrolytic specialists for several rare, uncultured populations. Genome-centric analyses of complex microbial communities across diverse environments provide the key to understanding the phylogenetic and metabolic diversity of these interactive communities. © 2016 Society for Applied Microbiology and John Wiley & Sons Ltd.

    Full Text Available There have been few taxonomic studies of centric diatoms in lotic freshwater environments in Brazil, especially in terms of those including nanoplanktonic forms, which are often neglected in studies of local floras, because of their small size or confusing taxonomy. This is the first study focusing on centric diatoms in the flora of the state of Bahia, in northeastern Brazil. Plankton and periphyton attached to Eichornia crassipes were collected in the winter of 2009 in the Cachoeira River. The diatoms were analyzed and described under light and electron microscopies. Seventeen infrageneric taxa were identified. Cyclotella was represented by five taxa, and concerning of similarities between diacritical features of species in this genus, their descriptions were thoroughly detailed. This was the first time that Cyclotella atomus var. marina, previously recorded only in coastal areas of Japan and Korea, has been documented in a river in South America. We also identified two diatom taxa previously unrecorded in the flora of Brazil: C. cryptica and C. meduanae. Finally, we present a detailed light, transmission and scanning electron microscopy analysis of Skeletonema potamos, a diatom rarely found in the Brazilian literature.

    Existing design guidelines for concrete hinges consider bending-induced tensile cracking, but the structural behavior is oversimplified to be time-independent. This is the motivation to study creep and bending-induced tensile cracking of initially monolithic concrete hinges systematically. Material tests on plain concrete specimens and structural tests on marginally reinforced concrete hinges are performed. The experiments characterize material and structural creep under centric compression as well as bending-induced tensile cracking and the interaction between creep and cracking of concrete hinges. As for the latter two aims, three nominally identical concrete hinges are subjected to short-term and to longer-term eccentric compression tests. Obtained material and structural creep functions referring to centric compression are found to be very similar. The structural creep activity under eccentric compression is significantly larger because of the interaction between creep and cracking, i.e. bending-induced cracks progressively open and propagate under sustained eccentric loading. As for concrete hinges in frame-like integral bridge construction, it is concluded (i) that realistic simulation of variable loads requires consideration of the here-studied time-dependent behavior and (ii) that permanent compressive normal forces shall be limited by 45% of the ultimate load carrying capacity, in order to avoid damage of concrete hinges under sustained loading.

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

    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.

    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.

    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.
