    2010-02-01

    In Uganda, environmental and natural resource management is decentralized and has been the responsibility of local districts since 1996. This environmental management arrangement was part of a broader decentralization process and was intended to increase local ownership and improve environmental policy; however, its implementation has encountered several major challenges over the last decade. This article reviews some of the key structural problems facing decentralized environmental policy in this central African country and examines these issues within the wider framework of political decentralization. Tensions have arisen between technical staff and politicians, between various levels of governance, and between environmental and other policy domains. This review offers a critical reflection on the perspectives and limitations of decentralized environmental governance in Uganda. Our conclusions focus on the need to balance administrative staff and local politicians, the mainstreaming of local environmental policy, and the role of international donors.

    Full Text Available During the early decade of the century, environmental international activities of subnational governments have attracted more and more interest from politicians and academics, supposing a topic of increasing research into new global environmental go- vernance. Is that the need for practical action to address global environmental problems, have made possible and given legitimacy to the gradual appearance of new forms of au- thority. This article analyzes the role of the governments of the Spanish Autonomous Communities (CCAA Spanish and Brazilian states in global environmental governance, especially in the international regime on climate change in the heart of the Network of Regional Governments for Sustainable Development (nrg4SD.

    Full Text Available Se analiza el concepto de "actores claves" en la generación de políticas ambientales. Independientemente de la definición de actor social que se maneje, el asumir la existencia de actores claves ofrece limitaciones conceptuales y prácticas, ya que éstos son coyunturales a cada situación específica. Todos pueden ser actores claves en generar políticas ambientales cumpliendo papeles diferenciales. Como alternativa se utiliza el término de "actores destacados" y se revisan aspectos sobresalientes de varios de ellos en América Latina. Seguidamente se postula que el análisis se debe centrar en los escenarios sociales donde esos actores se pueden manifestar. Se ofrece una distinción preliminar de escenarios que permite integrar a nuevos y viejos movimientos sociales y establecer relaciones de articulación y equivalencia.The concept of "key actors" in the field of environmental politics is analyzed. Beyond the definition of social actor, the assumption of the existence of key actors implies conceptual and practical limitations, as it depends of each specific situation. Everyone could be a key actor under differential roles in the generation of environmental politics. As an alternative, the term "noteworthy actors" is used and a brief review of them in Latin America is presented. The relevant question should address the social scenarios from where these actors can express themselves. A preliminary distinction of scenarios is presented, in which old and new social movements could be integrated and relationships of articulation and equivalence could be established.

  5. Actors or Spectators? Vulnerability and Critical Environmental Law

    Directory of Open Access Journals (Sweden)

    2013-12-01

    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

    The physical, spatial and land-use impacts of decentralized solar technologies applied at the community level by the year 2000 are examined. The results of the study are intended to provide a basis for evaluating the way in which a shift toward reliance on decentralized energy technologies may eventually alter community form. Six land-use types representative of those found in most US cities are analyzed according to solar penetration levels identified in the maximum solar scenario for the year 2000. The scenario is translated into shares of end use demand in the residential, commercial and industrial sectors. These proportions become the scenario goals to be met by the use of decentralized solar energy systems. The percentage of total energy demand is assumed to be 36.5 percent, 18.8 percent and 22.6 percent in the residential, commercial and industrial sectors respectively. The community level scenario stipulated that a certain percentage of the total demand be met by on-site solar collection, i.e. photovoltaic and thermal collectors, and by passive design. This on-site solar goal is 31.9 percent (residential), 16.8 percent (commercial) and 13.1 percent (industrial).

    Full Text Available Decentralized energy planning (DEP is looked upon as an indisputable opportunity for energy planning of villages, isolated islands, and far spots. Nonetheless, at this decentralized planning level, the value of demand-side resources is not fairly examined, despite enjoying great advantages. Therefore, the core task of this study is to integrate demand-side resources, as a competing solution against supply-side alternatives, with decentralized energy planning decisions and demonstrate the rewarding role it plays. Moreover, sustainability indicators (SIs are incorporated into DEP attempts in order to attain sustainable development. It is emphasized that unless these indicators are considered at lower energy planning levels, they will be ignored at higher planning levels as well. Hence, to the best knowledge of the authors, this study for the first time takes into account greenhouse gas (GHG emissions produced by utilization of renewable energies in DEP optimization models. To address the issues mentioned previously, multiobjective linear programming model along with a min-max goal programming approach is employed. Finally, using data taken from the literature, the model is solved, and the obtained results are discussed. The results show that DSM policies have remarkably contributed to significant improvements especially in terms of environmental indicators.

    2015-11-01

    Full Text Available The direction of sunshine or the installation sites of environmental control facilities in the greenhouse result in different temperature and humidity levels in the various zones of the greenhouse, and thus, the production quality of crop is inconsistent. This study proposed a wireless-networked decentralized fuzzy control scheme to regulate the environmental parameters of various culture zones within a greenhouse. The proposed scheme can create different environmental conditions for cultivating different crops in various zones and achieve diversification or standardization of crop production. A star-type wireless sensor network is utilized to communicate with each sensing node, actuator node, and control node in various zones within the greenhouse. The fuzzy rule-based inference system is used to regulate the environmental parameters for temperature and humidity based on real-time data of plant growth response provided by a growth stage selector. The growth stage selector defines the control ranges of temperature and humidity of the various culture zones according to the leaf area of the plant, the number of leaves, and the cumulative amount of light. The experimental results show that the proposed scheme is stable and robust and provides basis for future greenhouse applications.

    In Europe, the integration of decentralized renewable energy production in regional planning processes plays a crucial role. In particular, regions face a major challenge in order to set up renewable decentralized energy systems and incorporate them into the electricity grid. This paper presents a methodological concept and preliminary tests of applications in order to create an optimization model for an improved renewable energy development and planning practice: firstly, the energy potentials of micro renewable resources are estimated, and secondly the outcomes are combined with an estimation of resulting environmental impacts. Including these data into the spatial analysis, different scenarios can be developed in order to support decision making in landscape planning on the basis of environmental and landscape criteria as well as energy issues, including technical aspects and costs. The case study area is the Hannover region. First results show good energy potentials, which will be in a next step evaluated and combined with environmental impacts in order to improve energy efficiency by integrated renewable, decentralized power plants and energy mix.

    2010-06-01

    The reduction and reuse of composting leachate is an issue of importance in the field of decentralized solid waste management. In this study, composting leachate from source-separated food waste was treated and subsequently used as liquid fertilizer to irrigate Impatiens (Impatiens balsamina). The leachate was altered by adjusting storage time and dilution, and through addition of microbial inocula. For each test case, the effects of irrigation were monitored by analyzing the Impatiens extension degree, numbers of leaves and flowers, dry weight, and photosynthetic pigment content to assess fertilizer efficiency. The main results obtained revealed that the addition of microbial inocula and lengthening of storage times may lower COD concentrations, adjust pH value and maintain a comparatively high level of nutrient contents. By adding microbial inocula, a COD concentration of 9.6% and BOD(5) concentration of 6.7% were obtained for non-treated leachate with the same storage time. COD concentrations in leachate decreased to 69.4% after 36weeks storage. Moreover, composting leachate promoted growth of Impatiens. The dry weight biomass of Impatiens irrigated using treated diluted leachate was 1.15-2.94 times that obtained for Impatiens irrigated using tap water. Lastly, following the irrigation of Impatiens over a short period, soil did not accumulate VOCs and heavy metals to levels exceeding relative standards. Further research on heavy metal and salinity accumulation in plants should be undertaken to meet the needs of large-scale applications.

    本文从碳排放的角度,利用1998--2008年省级面板数据分析了财政分权与环境污染的关系,研究发现,财政分权与碳排放存在正相关关系,分权度的提高不利于碳排放量的减少,这说明财政分权可能会降低地方政府对碳排放管制的努力。提高产业研发强度有利于碳排放的降低,但贸易开放度的提高不利于碳排放量的减少。本文还发现,财政分权对碳排放的影响在不同能源消费结构,不同地理区位,不同环境政策的省份之间存在显著差异。此外,财政分权导致碳排放增加的影响途径主要是第二、第三产业。%This paper studies the relationship between fiscal decentralization and environmental pollution from the perspective of carbon emission, using provincial-level dynamic panel data from 1998 to 2008. It shows that there is positive correlated relationship between fiscal decentralization and environmental pollution, the increase of fiscal decentralization level doesn't help to reduce carbon emission. It is shows that local governments may not do their efforts to control carbon emissions for fiscal decentralization. The increase of R&D may help improve the reducing of carbon emissions, but when the opening extent of trade becomes higher, the negative impact on reduction of carbon emission made by fiscal decentralization will be decreased. The impact of fiscal decentralization on carbon emission varies greatly among provinces there are different energy consumption structure, different geographical location, and different environmental policy. The influence of fiscal decentralization increasing the carbon emission is through secondary industry and tertiary industry.

    Full Text Available Centralization and decentralization are key concepts in debates that focus on the (antidemocratic character of digital societies. Centralization is understood as the control over communication and data flows, and decentralization as giving it (back to users. Communication and media research focuses on centralization put forward by dominant digital media platforms, such as Facebook and Google, and governments. Decentralization is investigated regarding its potential in civil society, i.e., hacktivism, (encryption technologies, and grass-root technology movements. As content-based media companies increasingly engage with technology, they move into the focus of critical media studies. Moreover, as formerly nationally oriented companies now compete with global media platforms, they share several interests with civil society decentralization agents. Based on 26 qualitative interviews with leading media managers, we investigate (decentralization strategies applied by content-oriented media companies. Theoretically, this perspective on media companies as agents of (decentralization expands (decentralization research beyond traditional democratic stakeholders by considering economic actors within the “global informational ecosystem” (Birkinbine, Gómez, & Wasko, 2017. We provide a three-dimensional framework to empirically investigate (decentralization. From critical media studies, we borrow the (decentralization of data and infrastructures, from media business research, the (decentralization of content distribution.

    Full Text Available Computational toxicology combines data from high-throughput test methods, chemical structure analyses and other biological domains (e.g., genes, proteins, cells, tissues with the goals of predicting and understanding the underlying mechanistic causes of chemical toxicity and for predicting toxicity of new chemicals and products. A key feature of such approaches is their reliance on knowledge extracted from large collections of data and data sets in computable formats. The U.S. Environmental Protection Agency (EPA has developed a large data resource called ACToR (Aggregated Computational Toxicology Resource to support these data-intensive efforts. ACToR comprises four main repositories: core ACToR (chemical identifiers and structures, and summary data on hazard, exposure, use, and other domains, ToxRefDB (Toxicity Reference Database, a compilation of detailed in vivo toxicity data from guideline studies, ExpoCastDB (detailed human exposure data from observational studies of selected chemicals, and ToxCastDB (data from high-throughput screening programs, including links to underlying biological information related to genes and pathways. The EPA DSSTox (Distributed Structure-Searchable Toxicity program provides expert-reviewed chemical structures and associated information for these and other high-interest public inventories. Overall, the ACToR system contains information on about 400,000 chemicals from 1100 different sources. The entire system is built using open source tools and is freely available to download. This review describes the organization of the data repository and provides selected examples of use cases.

    2009-04-15

    Decentralized power generation is gaining significance in liberalized electricity markets. An increasing decentralization of power supply is expected to make a particular contribution to climate protection. This article investigates the advantages and disadvantages of decentralized electricity generation according to the overall concept of sustainable development. On the basis of a hierarchically structured set of sustainability criteria, four future scenarios for Germany are assessed, all of which describe different concepts of electricity supply in the context of the corresponding social and economic developments. The scenarios are developed in an explorative way according to the scenario method and the sustainability criteria are established by a discursive method with societal actors. The evaluation is carried out by scientific experts. By applying an expanded analytic hierarchy process (AHP), a multicriteria evaluation is conducted that identifies dissent among the experts. The results demonstrate that decentralized electricity generation can contribute to climate protection. The extent to which it simultaneously guarantees security of supply is still a matter of controversy. However, experts agree that technical and economic boundary conditions are of major importance in this field. In the final section, the article discusses the method employed here as well as implications for future decentralized energy supply. (author)

  2. Low Decision Space Means No Decentralization in Fiji

    Faguet, Jean-Paul

    2016-01-01

    Mohammed, North, and Ashton find that decentralization in Fiji shifted health-sector workloads from tertiary hospitals to peripheral health centres, but with little transfer of administrative authority from the centre. Decision-making in five functional areas analysed remains highly centralized. They surmise that the benefits of decentralization in terms of services and outcomes will be limited. This paper invokes Faguet’s (2012) model of local government responsiveness and accountability to explain why this is so – not only for Fiji, but in any country that decentralizes workloads but not the decision space of local governments. A competitive dynamic between economic and civic actors that interact to generate an open, competitive politics, which in turn produces accountable, responsive government can only occur where real power and resources have been devolved to local governments. Where local decision space is lacking, by contrast, decentralization is bound to fail because it has not really happened in the first place. PMID:27801361

    Aas, I H Monrad

    2006-01-01

    At present, most hospitals have a department of radiology where images are captured and interpreted. Decentralization is the opposite of centralization and means 'away from the centre'. With a Picture Archiving and Communication System (PACS) and broadband communications, transmitting radiology images between sites will be far easier than before. Qualitative interviews of 26 resource persons were performed in Norway. There was a response rate of 90%. Decentralization of radiology interpretations seems less relevant than centralization, but several forms of decentralization have a role to play. The respondents mentioned several advantages, including exploitation of capacity and competence. They also mentioned several disadvantages, including splitting professional communities and reduced contact between radiologists and clinicians. With the new technology decentralization and centralization of image interpretation are important possibilities in organizational change. This will be important for the future of teleradiology.

    Background The reservoir and mode of transmission of Mycobacterium ulcerans, the causative agent of Buruli ulcer, remain unknown. Ecological, genetic and epidemiological information nonetheless suggests that M. ulcerans may reside in aquatic protozoa. Methodology/Principal Findings We experimentally infected Acanthamoeba polyphaga with M. ulcerans and found that the bacilli were phagocytised, not digested and remained viable for the duration of the experiment. Furthermore, we collected 13 water, 90 biofilm and 45 detritus samples in both Buruli ulcer endemic and non-endemic communities in Ghana, from which we cultivated amoeboid protozoa and mycobacteria. M. ulcerans was not isolated, but other mycobacteria were as frequently isolated from intracellular as from extracellular sources, suggesting that they commonly infect amoebae in nature. We screened the samples as well as the amoeba cultures for the M. ulcerans markers IS2404, IS2606 and KR-B. IS2404 was detected in 2% of the environmental samples and in 4% of the amoeba cultures. The IS2404 positive amoeba cultures included up to 5 different protozoan species, and originated both from Buruli ulcer endemic and non-endemic communities. Conclusions/Significance This is the first report of experimental infection of amoebae with M. ulcerans and of the detection of the marker IS2404 in amoeba cultures isolated from the environment. We conclude that amoeba are potential natural hosts for M. ulcerans, yet remain sceptical about their implication in the transmission of M. ulcerans to humans and their importance in the epidemiology of Buruli ulcer.

    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.

    Shehabi, Arman; Stokes, Jennifer R.; Horvath, Arpad

    2012-06-01

    Both centralized and decentralized wastewater systems have distinct engineering, financial and societal benefits. This paper presents a framework for analyzing the environmental effects of decentralized wastewater systems and an evaluation of the environmental impacts associated with two currently operating systems in California, one centralized and one decentralized. A comparison of energy use, greenhouse gas emissions and criteria air pollutants from the systems shows that the scale economies of the centralized plant help lower the environmental burden to less than a fifth of that of the decentralized utility for the same volume treated. The energy and emission burdens of the decentralized plant are reduced when accounting for high-yield wastewater reuse if it supplants an energy-intensive water supply like a desalination one. The centralized facility also reduces greenhouse gases by flaring methane generated during the treatment process, while methane is directly emitted from the decentralized system. The results are compelling enough to indicate that the life-cycle environmental impacts of decentralized designs should be carefully evaluated as part of the design process.

    Sørensen, M. D.; Clausen, Jens

    2002-01-01

    Typically, ground staff scheduling is centrally planned for each terminal in an airport. The advantage of this is that the staff is efficiently utilized, but a disadvantage is that staff spends considerable time walking between stands. In this paper a decentralized approach for ground staff...... scheduling is investigated. The airport terminal is divided into zones, where each zone consists of a set of stands geographically next to each other. Staff is assigned to work in only one zone and the staff scheduling is planned decentralized for each zone. The advantage of this approach is that the staff...... work in a smaller area of the terminal and thus spends less time walking between stands. When planning decentralized the allocation of stands to flights influences the staff scheduling since the workload in a zone depends on which flights are allocated to stands in the zone. Hence solving the problem...

    Benjamin Miranda Tabak

    2003-12-01

    Full Text Available We use a mean-variance model to analyze the problem of decentralized portfolio management. We find the solution for the optimal portfolio allocation for a head trader operating in n different markets, which is called the optimal centralized portfolio. However, as there are many traders specialized in different markets, the solution to the problem of optimal decentralized allocation should be different from the centralized case. In this paper we derive conditions for the solutions to be equivalent. We use multivariate normal returns and a negative exponential function to solve the problem analytically. We generate the equivalence of solutions by assuming that different traders face different interest rates for borrowing and lending. This interest rate is dependent on the ratio of the degrees of risk aversion of the trader and the head trader, on the excess return, and on the correlation between asset returns.

  20. Decentralized Constraint Satisfaction

    CERN Document Server

    Duffy, K R; Leith, D J

    2011-01-01

    Constraint satisfaction problems (CSPs) lie at the heart of many modern industrial and commercial tasks. An important new collection of CSPs has recently been emerging that differ from classical problems in that they impose constraints on the class of algorithms that can be used to solve them. In computer network applications, these constraints arise as the variables within the CSP are located at physically distinct devices that cannot communicate. At each instant, every variable only knows if all its constraints are met or at least one is not. Consequently, the CSP's solution must be found using a decentralized approach. Existing algorithms for solving CSPs are either centralized or distributed, both of which violate these algorithmic constraints. In this article we present the first algorithm for solving CSPs that fulfills these new requirements. It is fully decentralized, making no use of a centralized controller or message-passing between variables. We prove that this algorithm converges with probability ...

    Full Text Available Decentralization in Indonesia is that reforms not completed and until the current implementation is not maximized or have not been successful. The essence of decentralization is internalising cost and benefit' for the people and how the government closer to the people. That's the most important essence of essence 'decentralization’. However, the implementation of decentralization in Indonesia is still far from the expectations. It is shown that only benefits of decentralization elite and local authorities, decentralization is a neo-liberal octopus, decentralization of public services are lacking in character, decentralization without institutional efficiency, decentralization fosters corruption in the area, and quasi-fiscal decentralization.

  2. Decentral Smart Grid Control

    Schäfer, Benjamin; Matthiae, Moritz; Timme, Marc; Witthaut, Dirk

    2015-01-01

    Stable operation of complex flow and transportation networks requires balanced supply and demand. For the operation of electric power grids—due to their increasing fraction of renewable energy sources—a pressing challenge is to fit the fluctuations in decentralized supply to the distributed and temporally varying demands. To achieve this goal, common smart grid concepts suggest to collect consumer demand data, centrally evaluate them given current supply and send price information back to customers for them to decide about usage. Besides restrictions regarding cyber security, privacy protection and large required investments, it remains unclear how such central smart grid options guarantee overall stability. Here we propose a Decentral Smart Grid Control, where the price is directly linked to the local grid frequency at each customer. The grid frequency provides all necessary information about the current power balance such that it is sufficient to match supply and demand without the need for a centralized IT infrastructure. We analyze the performance and the dynamical stability of the power grid with such a control system. Our results suggest that the proposed Decentral Smart Grid Control is feasible independent of effective measurement delays, if frequencies are averaged over sufficiently large time intervals.

  3. Medication as Infrastructure: Decentring Self-care

    Directory of Open Access Journals (Sweden)

    Peter Danholt

    2012-11-01

    Full Text Available Drawing on science and technology studies (STS, and specifically the concept of infrastructure as conceptualised by Bowker and Star (2000; Star 1999, this paper argues and empirically demonstrates that self-care may be considered a practice that is thoroughly sociotechnical, material, distributed and de-centred. Comparing the practices related to medication in the treatment of asthma, type 2 diabetes and haemophilia, we show that in practice there is no ‘self’ in self-care. More specifically, the ‘self’ in self-care is an actor who is highly dependent on, and intertwined with infrastructures of care, in order to be self-caring. Infrastructures of care are the more or less embedded ‘tracks’ along which care may ‘run’, shaping and being shaped by actors and settings along the way. Obtaining prescriptions, going to the pharmacy, bringing medication home and administering it as parts of daily life are commonplace activities embedded in the fabric of life, especially for those living with a chronic condition. However, this procurement and emplacement of medication involves the establishment and ongoing enactment of infrastructures of care, that is, the connections between various actors and locations that establish caring spaces and caring selves. Locations and actors are included as allies in treating chronic conditions outside the clinical setting, but these infrastructures may also be ambiguous, with respect to their effects; they may simultaneously contribute to the condition’s management and neglect. Particularly precarious is management at the fringes of healthcare infrastructure, where allies, routines and general predictability are scarce. We conclude by arguing that these insights may induce a greater sensitivity to existing infrastructures and practices, when seeking to introduce new infrastructures of care, such as those promoted under the headings of ‘telemedicine’ and ‘healthcare IT’.

    Full Text Available The remarkable progress in neuroscience contributes a great deal to the debate about topics such as "free will" and "intersubjectivity." The brain is considered to be the initial basis, the superior entity of human action and evolves more and more into an autonomous actor challenging the social and philosophical sciences to a somatic turn. The main aim of the symposium "Actor Brain" at Duisburg-Essen University, was to more precisely conceive the approaches taken by neuroscience in order to arrive at a better understanding of them and their implications. Due to the scientific diversity of the speakers, the final discussion could point out that the positions taken by the participants were not as incompatible as may be first assumed. The need for accurate and precise definitions of terms such as "action", "decision-making", and "free will" is accentuated as the complexity of the debate increases. URN: urn:nbn:de:0114-fqs0603241

  12. Subsidiarity in Principle: Decentralization of Water Resources Management

    Directory of Open Access Journals (Sweden)

    Ryan Stoa

    2014-05-01

    Full Text Available The subsidiarity principle of water resources management suggests that water management and service delivery should take place at the lowest appropriate governance level. The principle is attractive for several reasons, primarily because: 1 the governance level can be reduced to reflect environmental characteristics, such as the hydrological borders of a watershed that would otherwise cross administrative boundaries; 2 decentralization promotes community and stakeholder engagement when decision-making is localized; 3 inefficiencies are reduced by eliminating reliance on central government bureaucracies and budgetary constraints; and 4 laws and institutions can be adapted to reflect localized conditions at a scale where integrated natural resources management and climate change adaptation is more focused. Accordingly, the principle of subsidiarity has been welcomed by many states committed to decentralized governance, integrated water resources management, and/or civic participation. However, applications of decentralization have not been uniform, and in some cases have produced frustrating outcomes for states and water resources. Successful decentralization strategies are heavily dependent on dedicated financial resources and human resource capacity. This article explores the nexus between the principle of subsidiarity and the enabling environment, in the hope of articulating factors likely to contribute to, or detract from, the success of decentralized water resources management. Case studies from Haiti, Rwanda, and the United States’ Florida Water Management Districts provide examples of the varied stages of decentralization.

  14. Centralized versus Decentralized Information Systems

    Science.gov (United States)

    Hugoson, Mats-Åke

    This paper brings into question whether information systems should be centralized or decentralized in order to provide greater support for different business processes. During the last century companies and organizations have used different approaches for centralization and decentralization; a simple answer to the question does not exist. This paper provides a survey of the evolution of centralized and decentralized approaches, mainly in a Nordic perspective. Based on critical reflections on the situation in the end of the century we can discuss what we can learn from history to achieve alignment between centralized and decentralized systems and the business structure. The conclusion is that theories, management and practice for decisions on centralization or decentralization of information systems must be improved. A conscious management and control of centralization /decentralization of IT support is a vital question in the company or the organization, and this is not a task that can be handled only by IT-specialists. There is a need for business oriented IT management of centralization/decentralization.

    Full Text Available This work intends to present the environmental conflict initiated due to the installation of pipeline Ferrous Ressources S / A, in the micro region of Viçosa-MG, building an analysis of the positioning of the main social actors involved, as well as their respective relations of power. Thepipeline of Ferrous will connect the complex Beam Mine in Congonhas-MG, the port of Ferrous Ressources in Presidente Kennedy-ES in order to export iron ore. To do so, were used as methodological procedures: bibliographical research; document analysis; semi-structured interviews with different actors; and follow-up meetings of the Popular Campaign Against the Water and Pipeline Ferrous, public hearings and demonstrations taken place in the Viçosa. Furthermore, there was monitoring of the pipeline discussion in local newspapers and on blogs. Thus, this study demonstrated that the Ferrous company, which owns high economic and symbolic power, assumes the role of dominating the conflict. On the other hand, those affected and social movements against the construction of the project, are sometimes in the role of dominated, leaving them to articulate strategies of resistance to delay / stop the construction of the pipeline. The state, in turn, assumes different roles in this context, demonstrating thereby weakness in mediation and conflict management established by pipeline Ferrous mainly in the micro region of Viçosa-MG.

    In the article ‘Energy and air emission implications of a decentralized wastewater system’ published in Environmental Research Letters (2012 Environ. Res.

    GENI Project: Georgia Tech is developing a decentralized, autonomous, internet-like control architecture and control software system for the electric power grid. Georgia Tech’s new architecture is based on the emerging concept of electricity prosumers—economically motivated actors that can produce, consume, or store electricity. Under Georgia Tech’s architecture, all of the actors in an energy system are empowered to offer associated energy services based on their capabilities. The actors achieve their sustainability, efficiency, reliability, and economic objectives, while contributing to system-wide reliability and efficiency goals. This is in marked contrast to the current one-way, centralized control paradigm.

    Full Text Available The political communication in media era performs on two dimensions: the horizontal dimension – between political actors and journalists – and on vertical dimension – the media product is decentralized to the consumer public. In Social Media Era, the horizontal dimension completely disappears and the communication is routed by the online opinion leaders in the social groups. Thus, in the new public space, the main communication actors are not journalists and politicians, but publicreceptor, which plays the role of opinion leaders. In Social Media, we can talk a lot about “the power of the receptor”, that is decentralizing, without intermediaries, the political message to discuss it in the social groups to which they belong.

  6. 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.

    This study compared actors', partners', and observers' perceptions of the amount of sarcasm used by participants (n = 80) in videotaped conversations. Significant differences were found among perceptions of actors, partners, and observers. Of the three perspectives, actors perceived themselves as using the greatest amount of sarcasm, followed by partners' perceptions of actors. Observers perceived actors as using the least amount of sarcasm. Correlations conducted to assess whether partners and observers recognized actors' individual attempts at sarcasm during the conversations were generally low.

  12. Decentralized neural control application to robotics

    CERN Document Server

    Garcia-Hernandez, Ramon; Sanchez, Edgar N; Alanis, Alma y; Ruz-Hernandez, Jose A

    2017-01-01

    This book provides a decentralized approach for the identification and control of robotics systems. It also presents recent research in decentralized neural control and includes applications to robotics. Decentralized control is free from difficulties due to complexity in design, debugging, data gathering and storage requirements, making it preferable for interconnected systems. Furthermore, as opposed to the centralized approach, it can be implemented with parallel processors. This approach deals with four decentralized control schemes, which are able to identify the robot dynamics. The training of each neural network is performed on-line using an extended Kalman filter (EKF). The first indirect decentralized control scheme applies the discrete-time block control approach, to formulate a nonlinear sliding manifold. The second direct decentralized neural control scheme is based on the backstepping technique, approximated by a high order neural network. The third control scheme applies a decentralized neural i...

    Full Text Available A centralistic government model has become a trend in a number of developing countries, in which the ideosycretic aspect becomes pivotal key in the policy making. The situation constitutes authoritarianism, cronyism, and corruption. To break the impasse, the decentralized system is proposed to make people closer to the public policy making. Decentralization is also convinced to be the solution to create a good governance. But a number of facts in the developing countries demonstrates that decentralization indeed has ignite emerges backfires such as decentralized corruption, parochialism, horizontal conflict, local political instability and others. This article elaborates the theoretical framework on decentralization's ouput as the a double-edge knife. In a simple words, the concept of decentralization does not have a permanent relationship with the creation of good governance and development. Without substantive democracy, decentralization is indeed potential to be a destructive political instrument threating the state's future.

    2004-01-01

    A descriptive case study with multiple sites and a single level of analysis was carried out in four purposefully selected administrative districts of Uganda to investigate the effect of financial management systems under decentralization on malaria control. Data were primarily collected from 36 interviews with district managers, staff at health units and local leaders. A review of records and documents related to decentralization at the central and district level was also used to generate data for the study. We found that a long, tedious, and bureaucratic process combined with lack of knowledge in working with new financial systems by several actors characterized financial flow under decentralization. This affected the timely use of financial resources for malaria control in that there were funds in the system that could not be accessed for use. We were also told that sometimes these funds were returned to the central government because of non-use due to difficulties in accessing them and/or stringent conditions not to divert them to other uses. Our data showed that a cocktail of bureaucratic control systems, corruption and incompetence make the financial management system under decentralization counter-productive for malaria control. The main conclusion is that good governance through appropriate and efficient financial management systems is very important for effective malaria control under decentralization.

    Full Text Available ”Decentralization of protected forest management from central to district government has not yet been implemented effectively. This effectiveness depends on many factors that include policy contents and political process or discourse in the policy making process. This study aimsto: 1 analyze the discourse in policy making process of decentralization in the management of protected forests, 2 analyze the actors/networks and their interests and 3 find out policy space for future policy reform. Both quantitative and qualitative approaches were used in the study. The results show that there are three discourses in the policy-making process of decentralized management of protected forests, namely: i democratic discourse (with story line of externality and accountability, supported by an association forum of Indonesian district government and  decentralization experts; ii economic discourse (with story line of efficiency, supported by businessmen, Association of Indonesian Provincial Government and World Bank; and iii democratic and economic discourses. The House of Representatives (DPR and Ministry of Home Affairs have authorities and capacities to integrate two discourses. Redefining of externality and interdependency can be used as narratives of new policies to improve the policy of decentralized protected forest management.

    Historically, domestic wastewaters are collected in large sewerage networks, transporting the waste from the site of production to the site of treatment (if implemented). For such systems, large civil and infra-structural investments (like electricity supply) are required, generally paid by the authorities from the tax income. In addition, in order to prevent clogging, a substantial amount of clean, and often potable, water is required which subsequently results in a dilution of the concentrated waste. The treatment systems, which need to be, developed to treat the huge flows of diluted wastewater, are extremely expensive and consume large amounts of energy. Moreover, the installed sewerage often suffers from lack of maintenance leading to huge losses of wastewater (particularly in the less prosperous countries). From the environmental engineering point of view, the generally applied centralised sanitation concept can be questioned. Concentrated wastes are relatively easy to manage while diluted wastes require large investments for purification. Obviously, many places are already served with sewer systems and a certain extent of sewerage will always be needed. Nonetheless, the extent to which this will be brought to practice needs reconsideration. This applies for a more decentralised approach. Also when decentralised sanitation and reuse (DESAR) is applied, different approaches are possible. It should become clear that the choice for the collection and transport system would determine for an important part the subsequent treatment and reuse. At the other hand the type of use, will determine the extent of treatment. The types of reuse will for important parts determine the extent of post treatment needed especially the removal of pathogens. (orig.)

    财政分权体现了中央政府和地方政府间的财政权力分配关系,它可以通过支出分权度和收入分权度两个指标进行衡量.从理论上分析,大多数研究结论都认为财政分权与污染量排放存在负激励,但是缺乏相应的实证研究.本文利用1998年到2009年的省级面板数据,对中国财政分权与污染物排放规模之间的关系进行了实证分析.本文选取工业废气排放量、工业固体废弃物排放量、工业废水排放量和二氧化硫排放量作为衡量污染物排放规模的指标,选择支出分权度与收入分权度作为解释变量,选择人均GDP、人口密度、城市化水平、外商投资总额、工业化水平作为控制变量.本文还将所有省份按照地理位置划分为东部和中西部两组进行稳健性检验.研究结果表明:以支出分权度衡量的财政分权指标与污染物排放规模负相关,且实证结果具有稳健性,以收入分权度衡量的财政分权指标与污染物排放规模的关系从实证的角度来讲不确定.%Fiscal decentralization reflects the distribution financial power between the central government and local government. It can be measured through the two indicators which are expenditure decentralization and revenue decentralization. From the theoretical analysis, most studies have concluded that there is a negative incentive between the fiscal decentralization and the amount of pollutant discharge, but lacks the empirical research. Utilizing the provincial panel data from 1998 to 2009, this paper carried on the empirical analysis about the relationship between China' s fiscal decentralization and the scale of pollutant discharge. The industrial waste gas discharge amount, industrial solid wastes discharge amount, industrial waste water discharge amount and sulfur dioxide discharge amount were selected as the indicators to measure the scale of pollutant discharge in the paper.

    Full Text Available Environmental and resource regimes, operating at different levels of social organization, vary in terms of factors such as the sources of actor behavior, the knowledge available to actors, the operation of compliance mechanisms, the use of policy instruments, and the nature of the broader social setting. Cross-level interactions among scale-dependent regimes can result in patterns of dominance, separation, merger, negotiated agreement, or system change. The mechanisms that determine which of these patterns will occur include authority/power differentials, limits of decentralization, dueling discourses, cognitive transitions, and blocking coalitions. Recurrent linkages or syndromes occur in this realm, e.g., limitations of authority and power regularly produce negotiated agreements in such forms as comanagement arrangements. The consequences of these interactions are often far-reaching as measured in terms of ecological sustainability, social welfare/efficiency, cultural values, and robustness.

    Full Text Available Recent discussions on REDD+ (Reducing Emissions from Deforestation and Forest Degradation, plus conservation, sustainable management of forests and enhancement of forest carbon stocks have raised optimism about reducing carbon emissions and deforestation in tropical countries. If approved under the United Nations Framework Convention on Climate Change (UNFCCC, REDD+ mechanisms may generate a substantial influx of financial resources to developing countries. Some authors argue that this money could reverse the ongoing process of decentralization of forest policies that has spread through a large number of developing countries in the past two decades. Central states will be accountable for REDD+ money, and may be compelled to control and keep a significant share of REDD+ funds. Supporters of decentralization argue that centralized implementation of REDD+ will be ineffective and inefficient. In this paper, I examine the relation between subnational governments and REDD+ in Brazil. Data show that some state governments in the Brazilian Amazon have played a key role in creating protected areas (PAs after 2003, which helped decrease deforestation rates. Governors have different stimuli for creating PAs. Some respond to the needs of their political constituency; others have expectations to boost the forest sector so as to increase fiscal revenues. Governors also have led the discussion on REDD+ in Brazil since 2008. Considering their interests and political power, REDD+ is unlikely to curb decentralization in Brazil.

    Full Text Available Key challenge in transitional countries is effective decentralized local governance with strong capacities for dealing with new rural development programming instruments. In this paper we have examined the attitudes of local rural development actors (RDA in Serbia on rural development policy priorities, in particular their attitudes on beneficiaries of rural development measures, policy objectives, and the most efficient strategies of rural development. We also analysed whether the respondents' attitudes differ depending on the socio-economic characteristic of surveyed regions (South and North of Serbia. Data on attitudes of RDAs were collected through direct survey with representatives of 30 rural communities, and analysed using descriptive statistics methods and Ajzen's theory of planned behaviour. Results indicate that respondents' attitudes on rural policy are conservative and oriented towards objectives related to agriculture and interests of farmers and that socio-economic characteristic of the regions contribute to distinction in attitudes of RDAs.

  5. The material politics of waste disposal - decentralization and integrated systems

    Directory of Open Access Journals (Sweden)

    2012-12-01

    Full Text Available This article and the previous «Convergence and divergence between the local and regional state around solid waste management. An unresolved problem in the Sacred Valley» from Teresa Tupayachi are published as complementary accounts on the management of solid waste in the Vilcanota Valley in Cusco. Penelope Harvey and Teresa Tupayachi worked together on this theme. The present article explores how discontinuities across diverse instances of the state are experienced and understood. Drawing from an ethnographic study of the Vilcanota Valley in Cusco, the article looks at the material politics of waste disposal in neoliberal times. Faced with the problem of how to dispose of solid waste, people from Cusco experience a lack of institutional responsibility and call for a stronger state presence. The article describes the efforts by technical experts to design integrated waste management systems that maximise the potential for re-cycling, minimise toxic contamination, and turn ‘rubbish’ into the altogether more economically lively category of ‘solid waste’. However while the financialization of waste might appear to offer an indisputable public good, efforts to instigate a viable waste disposal business in a decentralizing political space elicit deep social tensions and contradictions. The social discontinuities that decentralization supports disrupt ambitions for integrated solutions as local actors resist top-down models and look not just for alternative solutions, but alternative ways of framing the problem of urban waste, and by extension their relationship to the state.

    Many organizations in various industries have tended to move away from strict centralization, yet some centralization is still vital to top management. With 19 of the 22 executives interviewed favoring or implementing some form of decentralization, it is probable that traditionally centralized organizations will follow the trend and begin to decentralize their organizational structures. The incentives and advantages of decentralization are too attractive to ignore. Decentralization provides responsibility, clear objectives, accountability for results, and more efficient and effective decision making. However, one must remember that decentralization can be overextended and that centralization is still viable in certain functions. Finding the correct balance between control and autonomy is a key to decentralization. Too much control and too much autonomy are the primary reasons for decentralization failures. In today's changing, competitive environment, structures must be continuously redefined, with the goal of finding an optimal balance between centralization and decentralization. Organizations are cautioned not to seek out and install a single philosopher-king to impose unified direction, but to unify leadership goals, participation, style, and control to develop improved methods of making all responsible leaders of one mind about the organization's needs and goals.

    2013-01-01

    Background During the 1990s, the government of Tanzania introduced the decentralization by devolution (D by D) approach involving the transfer of functions, power and authority from the centre to the local government authorities (LGAs) to improve the delivery of public goods and services, including health services. Objective This article examines and documents the experiences facing the implementation of decentralization of health services from the perspective of national and district officials. Design The study adopted a qualitative approach, and data were collected using semi-structured interviews and were analysed for themes and patterns. Results The results showed several benefits of decentralization, including increased autonomy in local resource mobilization and utilization, an enhanced bottom-up planning approach, increased health workers’ accountability and reduction of bureaucratic procedures in decision making. The findings also revealed several challenges which hinder the effective functioning of decentralization. These include inadequate funding, untimely disbursement of funds from the central government, insufficient and unqualified personnel, lack of community participation in planning and political interference. Conclusion The article concludes that the central government needs to adhere to the principles that established the local authorities and grant more autonomy to them, offer special incentives to staff working in the rural areas and create the capacity for local key actors to participate effectively in the planning process.

    2015-01-01

    While many large infrastructure networks, such as power, water, and natural gas systems, have similar physical properties governing flows, these systems tend to have distinctly different sizes and topological structures. This paper seeks to understand how these different size-scales and topological features can emerge from relatively simple design principles. Specifically, we seek to describe the conditions under which it is optimal to build decentralized network infrastructures, such as a microgrid, rather than centralized ones, such as a large high-voltage power system. While our method is simple it is useful in explaining why sometimes, but not always, it is economical to build large, interconnected networks and in other cases it is preferable to use smaller, distributed systems. The results indicate that there is not a single set of infrastructure cost conditions under which optimally-designed networks will have highly centralized architectures. Instead, as costs increase we find that average network size...

    2014-01-01

    Full Text Available Bitcoin is the first decentralized peer-to-peer crypto-currency founded in 2009. Its main specificity is the fact that there is no issuer of this currency. On the other hand, the supply of this currency is software-programmed and limited. Among other things, its main features are relatively secure payments, low transaction costs, anonymity, inability of counterfeiting, irreversibility of transactions, but also extremely unstable exchange rate. Despite many advantages, the use of this currency is subject of numerous discussions, as this currency offers the possibility of performing various abuses and criminal activities. The future of this and other currencies in this regard depends on both security and privacy of these currencies, and legal regulation of such payments.

  6. Decentralized Consistent Updates in SDN

    KAUST Repository

    Nguyen, Thanh Dang

    2017-04-10

    We present ez-Segway, a decentralized mechanism to consistently and quickly update the network state while preventing forwarding anomalies (loops and blackholes) and avoiding link congestion. In our design, the centralized SDN controller only pre-computes information needed by the switches during the update execution. This information is distributed to the switches, which use partial knowledge and direct message passing to efficiently realize the update. This separation of concerns has the key benefit of improving update performance as the communication and computation bottlenecks at the controller are removed. Our evaluations via network emulations and large-scale simulations demonstrate the efficiency of ez-Segway, which compared to a centralized approach, improves network update times by up to 45% and 57% at the median and the 99th percentile, respectively. A deployment of a system prototype in a real OpenFlow switch and an implementation in P4 demonstrate the feasibility and low overhead of implementing simple network update functionality within switches.

    2014-08-01

    This paper presents the studies made on the definition and design of a decentralized and modular electrical architecture that can be used for power distribution, active thermal control (ATC), standard inputs-outputs electrical interfaces.Traditionally implemented inside central unit like OBC or RTU, these interfaces can be dispatched in the satellite by using MicroRTU.CNES propose a similar approach of MicroRTU. The system is based on a bus called BRIO (Bus Réparti des IO), which is composed, by a power bus and a RS485 digital bus. BRIO architecture is made with several miniature terminals called BTCU (BRIO Terminal Control Unit) distributed in the spacecraft.The challenge was to design and develop the BTCU with very little volume, low consumption and low cost. The standard BTCU models are developed and qualified with a configuration dedicated to ATC, while the first flight model will fly on MICROSCOPE for PYRO actuations and analogue acquisitions. The design of the BTCU is made in order to be easily adaptable for all type of electric interface needs.Extension of this concept is envisaged for power conditioning and distribution unit, and a Modular PCDU based on BRIO concept is proposed.

    Decentralized and sustainable energy development is now taking off in many corners of the world. 150,000 battery charging windmills operating among nomads in Inner Mongolia (China), hundreds of thousands family biogas plants providing energy and fertilizer for rural people in India, 1,000,000 efficient charcoal stoves manufactured and sold by small local companies in Kenya, 500 MW of wind power installed by rural cooperatives in Denmark are just a few examples. Because of the social and environmental benefits and of the possibilities for substitution of oil, such decentralized systems can be highly relevant to small island states. (au)

    Full Text Available Moving towards a low-carbon society calls not only for technological innovation, but also for new modes of governance. However, the current legal framework of the electricity sector, and the modes of governance that it establishes, impede innovation in the sector. To overcome this obstacle, in 2015 the Dutch government adopted a Crown decree for experiments with decentralized renewable electricity generation (Experimentation Decree with the aim to generate insights on how to adjust the legal framework. The question remains whether regulation is being adopted to real-life settings, i.e., which lessons can be learned from experimentally acquired results regarding new modes of governance for decentralized electricity systems? To answer this question we apply an interdisciplinary approach: we investigate which modes of governance are established in the Experimentation Decree (legal research and which ones are implemented in nine projects (governance research. Under the Decree, associations have to carry out all tasks in the electricity supply chain and can engage in collective generation, peer-to-peer supply and system operation. Other modes of governance, new actors for emerging activities and consumer involvement are limited. We conclude that the Experimentation Decree is too restricted regarding new modes of governance for a decentralized electricity system in real-life settings.

    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.

    There has been substantial progress with formal models for sequential decision making by individual agents using the Markov decision process (MDP). However, similar treatment of multi-agent systems is lacking. A recent complexity result, showing that solving decentralized MDPs is NEXP-hard, provides a partial explanation. To overcome this complexity barrier, we identify a general class of transition-independent decentralized MDPs that is widely applicable. The class consists of independent collaborating agents that are tied up by a global reward function that depends on both of their histories. We present a novel algorithm for solving this class of problems and examine its properties. The result is the first effective technique to solve optimally a class of decentralized MDPs. This lays the foundation for further work in this area on both exact and approximate solutions.

    2011-07-01

    The gasifier plays a key role in the operation of the whole IGCC power plant. It is a typical multivariable control system with strict constraints on the inputs and outputs which makes it very difficult to control. This paper presents a partially decentralized controller design method based on the stabilizer idea. The method only requires identifying some closed-loop transfer functions and solving an H(∞) optimization problem. The final partially decentralized controller is easy to implement and test in practice. Two partially decentralized controllers are designed for the ALSTOM gasifier benchmark problem, and simulation results show that they both meet the design specifications. Copyright © 2011 ISA.

    Full Text Available Beginning with the proposition that a true process of decentralization must necessarily be a process of democratization, such a process is understood as a privileged instrument for participation. Indeed, for a deepening of democratic practices, the ways which should be taken are via decentralization and social participation. This article describes and analyzes the experience of decentralization in Montevideo, a fundamental project created by the coalition of leftist parties that have governed the capital of Uruguay since 1990, a project which had no historical antecedents in the country. The department of Montevideo divided into 18 zones and created juntas locales (local boards - local, decentralized politicalorgans with representation from all the parties - and neighborhood councils. The Neighborhood Councils are representative organs that voice the neighborhood’s interests. Not integrated in the public municipal structure, these constitute private civil society organizations. They are consultative and consultancy bodies with the important tasks of initiative and proposal, planning, consultation, evaluation and the control over the communal management. Also described in the article is the methodology for the project’s improvement and progressive sophistication, which is in function of, among other factors, the degree of effectiveness and reaching of objectives that emerge from the permanent control and evaluation carried out year to year. The strategy presented emphasizes the need for ensuring that the community directly monitors and controls the process of municipal management to safeguard the democratic character of the process.

  7. Towards a Decentralized Magnetic Indoor Positioning System

    Directory of Open Access Journals (Sweden)

    Zakaria Kasmi

    2015-12-01

    Full Text Available Decentralized magnetic indoor localization is a sophisticated method for processing sampled magnetic data directly on a mobile station (MS, thereby decreasing or even avoiding the need for communication with the base station. In contrast to central-oriented positioning systems, which transmit raw data to a base station, decentralized indoor localization pushes application-level knowledge into the MS. A decentralized position solution has thus a strong feasibility to increase energy efficiency and to prolong the lifetime of the MS. In this article, we present a complete architecture and an implementation for a decentralized positioning system. Furthermore, we introduce a technique for the synchronization of the observed magnetic field on the MS with the artificially-generated magnetic field from the coils. Based on real-time clocks (RTCs and a preemptive operating system, this method allows a stand-alone control of the coils and a proper assignment of the measured magnetic fields on the MS. A stand-alone control and synchronization of the coils and the MS have an exceptional potential to implement a positioning system without the need for wired or wireless communication and enable a deployment of applications for rescue scenarios, like localization of miners or firefighters.

    Lone-actor terrorist attacks have risen to the forefront of the public's consciousness in the past few years. Some of these attacks were conducted against public officials. The rise of hard-to-detect, low-tech attacks may lead to more public officials being targeted. This paper explores whether different behavioral traits are apparent within a sample of lone-actor terrorists who plotted against high-value targets (including public officials) than within a sample of lone actors who plotted against members of the public. Utilizing a unique dataset of 111 lone-actor terrorists, we test a series of hypotheses related to attack capability and operational security. The results indicate that very little differentiates those who attack high-value targets from those who attack members of the public. We conclude with a series of illustrations to theorize why this may be the case. Copyright © 2016 John Wiley & Sons, Ltd.

    Full Text Available The aim of the article. The aim of the article is to define and propose the directions to solve the recent problems of financing public ecological services in the conditions of fiscal decentralization. The results of the analysis. This paper analyzes the decentralization reform impact on the possibilities of local authorities to finance the public ecological services in Ukraine. Advantages and threats of decentralizing reform are defined on the basis of theoretical vision of fiscal federalism in different state structures. The authors assessed basic central government documents in which the strategy and tactic of development. The lack of particular measures that are directed to the sustainable nature use on state level is defined. In practice, this means transference of financing powers from central to local government. Such process needs to be conducted with respective changes of financial flows directions and establishing effective forming and distributive tools. Traditionally, one of such tools, which are most appropriate to accumulate public environmental funds, is ecological tax. The study revealed that the enhancement of general fund of local budget revenues by local tax make the Local Environmental foundations' work impossible. Another initiative of central government is to transfer more than half revenues from the tax to the regional level. Such decision will be practicable only if impartial, formula based mechanism of subsequent allocation of funds between basic local authorities is developed. Scale projects now are funded by regional authorities. Authors proved that the better way to finance public ecological services on complementary basis is the local authorities’ cooperation. One of the advantages of such cooperation is the considering of the opportunities of self-taxation. This voluntary fiscal tool in Ukrainian European future must be stable source for financing of public ecological services. Decentralization reform also

    2008-01-01

    A file transfer algorithm based on ADP (autonomous decentralized protocol) was proposed to solve the problem that the ADS (autonomous decentralized system) middleware (NeXUS/Dlink) lacks of file transfer functions for Windows. The algorithm realizes the peer-to-peer file transfer, one-to-N inquiry/multi-response file transfer and one-to-N file distribution in the same data field based on communication patterns provided by the ADP. The peer-to-peer file transfer is implemented through a peer-to-peer communication path, one-to-N inquiry/multi-response file transfer and one-to-N file distribution are implemented through multicast commtmieation. In this algorithm, a file to be transferred is named with a GUID ( global unique identification), every data packet is marked with a sequence number, and file-receiving in parallel is implemented by caching DPOs (data processing objects) and multithread technologies. The algorithm is applied in a simulation system of the decentralized control platform, and the test results and long time stable mrming prove the feasibility of the algorithm.

  5. Query Optimizations over Decentralized RDF Graphs

    Abdelaziz, Ibrahim

    2017-05-18

    Applications in life sciences, decentralized social networks, Internet of Things, and statistical linked dataspaces integrate data from multiple decentralized RDF graphs via SPARQL queries. Several approaches have been proposed to optimize query processing over a small number of heterogeneous data sources by utilizing schema information. In the case of schema similarity and interlinks among sources, these approaches cause unnecessary data retrieval and communication, leading to poor scalability and response time. This paper addresses these limitations and presents Lusail, a system for scalable and efficient SPARQL query processing over decentralized graphs. Lusail achieves scalability and low query response time through various optimizations at compile and run times. At compile time, we use a novel locality-aware query decomposition technique that maximizes the number of query triple patterns sent together to a source based on the actual location of the instances satisfying these triple patterns. At run time, we use selectivity-awareness and parallel query execution to reduce network latency and to increase parallelism by delaying the execution of subqueries expected to return large results. We evaluate Lusail using real and synthetic benchmarks, with data sizes up to billions of triples on an in-house cluster and a public cloud. We show that Lusail outperforms state-of-the-art systems by orders of magnitude in terms of scalability and response time.

    Full Text Available Recent years have witnessed an increasing availability of heterogeneous sensor networks that consist of a large number of resource constrained nodes (sensors and a small number of powerful resource rich nodes (actors. Such heterogeneous Wireless Sensor Actor Network (WSANs offer improvement of sensor networks' capacity/coverage, energy conservation and network lifetime. This paper investigates the case where sensors are organized into clusters and mobile actors are used for maintaining an energy efficient topology by periodically manipulating their geographical position. We present an elegant technique that allows actor nodes to find an optimal geographical location with respect to their associated cluster heads such that the overall energy consumed is minimized. The proposed technique includes a weighted cost function based on the residual energy levels of cluster heads that allows the mobile actor to optimally fine-tune its geographical location. We present simulation results that demonstrate a significant increase of network lifetime over the traditional cluster based WSN deployments.

    1993-09-01

    Perceivers who observe social behaviors may form impressions not only of actors' traits but also of people as targets and of interpersonal relationships. In Study 1, Ss read about 4 individuals' behaviors under instructions to form actor-, target-, and relationship-based impressions. Ss then read additional behavioral information that they later tried to recall. Ss accurately perceived actor, target, and relationship effects in the presented information, and they better recalled subsequent behaviors that were consistent with all 3 types of impressions. In Study 2, Ss thought of 4 people they knew and judged how much each liked the other 3. These ratings revealed actor, target, and relationship effects as well as individual and dyadic reciprocity. Perceivers can form relatively accurate impressions of people as actors and as targets and accurate impressions of relationships between people, and these impressions influence memory for further behaviors.

    a changing set of key relations and alliances in development – those between business and consumers; ngos and celebrities; philanthropic organisations and the state; diaspora groups and transnational advocacy networks; ruling elites and productive capitalists; and ‘new donors’ and developing country......‘New actors and alliances in development’ brings together an interdisciplinary group of scholars exploring how development financing and interventions are being shaped by a wider and more complex platform of actors than usually considered in the existing literature. The contributors also trace...... governments. Despite the diversity of these actors and alliances, several commonalities arise: they are often based on hybrid transnationalism and diffuse notions of development responsibility; rather than being new per se, they are newly being studied as practices that are now coming to be understood...

  9. Dynamic Teams and Decentralized Control Problems with Substitutable Actions

    OpenAIRE

    Asghari, Seyed Mohammad; Nayyar, Ashutosh

    2016-01-01

    This paper considers two problems -- a dynamic team problem and a decentralized control problem. The problems we consider do not belong to the known classes of "simpler" dynamic team/decentralized control problems such as partially nested or quadratically invariant problems. However, we show that our problems admit simple solutions under an assumption referred to as the substitutability assumption. Intuitively, substitutability in a team (resp. decentralized control) problem means that the ef...

    How does political decentralization affect the frequency and costliness of bribe extraction by corrupt officials? Previous empirical studies, using subjective indexes of perceived corruption and mostly fiscal indicators of decentralization, have suggested conflicting conclusions. In search of more precise findings, we combine and explore two new data sources—an original cross-national data set on particular types of decentralization and the results of a firm level survey conducted in 80 count...

    2012-04-01

    Evaluative research into the capability of decentralized management of epidemiological vigilance (EV) was conducted in the operational, organizational and sustainable dimensions in the state of Bahia, Brazil. The quantitative approach was used in the construction of a baseline, with primary data obtained through an online questionnaire answered by thirty-eight municipal EV managers. In the qualitative approach to analyze the context and assess the management capability of municipalities in two case studies, techniques adapted to the analysis of discursive practices were used. This was done through semi-structured interviews with managers of regional and municipal government, health workers and representatives of the municipal health council. The case studies showed that the municipality with enhanced management capability is that in which the manager has the greatest potential of using the resources of his position, in addition to his ability to control, negotiate and coordinate with other actors. Due to decentralization of EV, considering the shared nature of management between the three spheres of government, there is a marked variation in the management capability of municipalities, determined by social, economic, political inequalities and management mechanisms adopted.

  17. Empathy and attribution: turning observers into actors.

    Science.gov (United States)

    Regan, D T; Totten, J

    1975-11-01

    A laboratory experiment was conducted to test Jones and Nisbett's information-processing explanation of the often-observed tendency for individuals (actors) to provide relatively more situational and less dispositional causal attributions for their behavior than those provided by observers of the same behavior. According to this explanation, aspects of the situation are phenomenologically more salient for actors, whereas characteristics of the actor and his behavior are more salient for observers. To test this explanation, the phenomenological perspective of observers are altered without making available any additional information. Subjects watched a videotape of a get-acquainted conversation after instructions either to observe a target conversant or to empathize with her. As predicted, taking the perspective of the target through empathy resulted in attributions that were relatively more situational and less dispositional than attributions provided by standard observers. The results support Jones and Nisbett's information-processing explanation of actor-observer attributional differences, and shed additional light on the process of empathy.

  1. Off-Policy Actor-Critic

    CERN Document Server

    Degris, Thomas; Sutton, Richard S

    2012-01-01

    This paper presents the first actor-critic algorithm for off-policy reinforcement learning. Our algorithm is online and incremental, and its per-time-step complexity scales linearly with the number of learned weights. Previous work on actor-critic algorithms is limited to the on-policy setting and does not take advantage of the recent advances in off-policy gradient temporal-difference learning. Off-policy techniques, such as Greedy-GQ, enable a target policy to be learned while following and obtaining data from another (behavior) policy. For many problems, however, actor-critic methods are more practical than action value methods (like Greedy-GQ) because they explicitly represent the policy; consequently, the policy can be stochastic and utilize a large action space. In this paper, we illustrate how to practically combine the generality and learning potential of off-policy learning with the flexibility in action selection given by actor-critic methods. We derive an incremental, linear time and space complexi...

  2. 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.

  4. Topographical Evaluation of the Decentration of Orthokeratology Lenses

    Institute of Scientific and Technical Information of China (English)

    Xiao Yang; Xingwu Zhong; Xiangming Gong; Junwen Zeng

    2005-01-01

    Purpose: To evaluate the amount of lens decentration and various factors affecting decentration after orthokeratology lens wear and to observe the effect of decentration on the visual functions.Methods: Two kinds of orthokeratology lenses were fitted to 270 eyes of 135 patients [initial mean refractive error: (-3.98±1.51)D]. Humphery Instruments ATLAS 990 was used for the computer-assisted analysis of corneal topographical maps. The examination of corneal topography was performed on patients before and after 6 months of wearing orthokeratology lenses. The amount of decentration of orthokeratology lenses was measured by finding the distance between center of optic zone and the pupil center. The factors influencing the amount of decentration were analyzed, including the initial refraction error, astigmatism, keratometry values, corneal eccentricity, and the diameter of lens.Visual symptoms including monocular diplopia, glare around lights were recorded to evaluate the effects of decentration on visual functions.Results: The mean amount of decentration was (0.49±0.34) mm after one night's wear.The mean amount of decentration after 1 month, 3 months and 6 months was (0.57±0.41) mm, (0.55±0.48) mm and (0.59±0.39) mm, respectively. After one month, the amount of decentration was less than 0.50 mm in 51.1% eyes, 0.50~1.0 mm in 35.6% eyes and more than 1.00 mm in 13.3% eyes. The direction of decentration of more than 0.50 mm was mainly in the temporal quadrant (48.5%). Patients with greater initial astigmatism and smaller lenses showed greater decentration (P<0.05). There was no statistically significant difference in decentration between the two groups with different corneal eccentricities and keratometry values (P>0.05). The amount of decentration was greater in patients who complained of monocular diplopia and glare.Conclusions: The amount of decentration of orthokeratology depends on the initial refractive error, astigmatism and the design of orthokeratology

  7. Tractable problems in optimal decentralized control

    Science.gov (United States)

    Rotkowitz, Michael Charles

    2005-07-01

    This thesis considers the problem of constructing optimal decentralized controllers. The problem is formulated as one of minimizing the closed-loop norm of a feedback system subject to constraints on the controller structure. The notion of quadratic invariance of a constraint set with respect to a system is defined. It is shown that quadratic invariance is necessary and sufficient for the constraint set to be preserved under feedback. It is further shown that if the constraint set has this property, this allows the constrained minimum-norm problem to be solved via convex programming. These results are developed in a very general framework, and are shown to hold for continuous-time systems, discrete-time systems, or operators on Banach spaces, for stable or unstable plants, and for the minimization of any norm. The utility of these results is then demonstrated on some specific constraint classes. An explicit test is derived for sparsity constraints on a controller to be quadratically invariant, and thus amenable to convex synthesis. Symmetric synthesis is also shown to be quadratically invariant. The problem of control over networks with delays is then addressed as another constraint class. Multiple subsystems are considered, each with its own controller, such that the dynamics of each subsystem may affect those of other subsystems with some propagation delays, and the controllers may communicate with each other with some transmission delays. It is shown that if the communication delays are less than the propagation delays, then the associated constraints are quadratically invariant, and thus optimal controllers can be synthesized. We further show that this result still holds in the presence of computational delays. This thesis unifies the few previous results on specific tractable decentralized control problems, identifies broad and useful classes of new solvable problems, and delineates the largest known class of convex problems in decentralized control.

    In the minimum cost spanning tree model we consider decentralized pricing rules, i.e. rules that cover at least the ecient cost while the price charged to each user only depends upon his own connection costs. We de ne a canonical pricing rule and provide two axiomatic characterizations. First......, the canonical pricing rule is the smallest among those that improve upon the Stand Alone bound, and are either superadditive or piece-wise linear in connection costs. Our second, direct characterization relies on two simple properties highlighting the special role of the source cost....

  10. P2P Techniques for Decentralized Applications

    CERN Document Server

    2012-01-01

    As an alternative to traditional client-server systems, Peer-to-Peer (P2P) systems provide major advantages in terms of scalability, autonomy and dynamic behavior of peers, and decentralization of control. Thus, they are well suited for large-scale data sharing in distributed environments. Most of the existing P2P approaches for data sharing rely on either structured networks (e.g., DHTs) for efficient indexing, or unstructured networks for ease of deployment, or some combination. However, these approaches have some limitations, such as lack of freedom for data placement in DHTs, and high late

  11. Worlds Apart: A Social Theoretical Exploration of Local Networks, Natural Actors, and Practitioners of Rural Development in Southern Honduras

    Directory of Open Access Journals (Sweden)

    Brian J. Gareau

    2012-07-01

    Full Text Available This paper explores the importance of incorporating the socioecological realities of alternative networks into analyses of rural development. Cultural theory is examined, which provides a base upon which rural development can identify difference in worldviews based on difference in sociological conditions and environmental phenomena. Actor-oriented theory problematizes the ideal types of cultural theory, providing a means of give-and-take between actors’ worldviews of different networks. Actor-network theory breaks down the nature-culture dichotomy of actor-oriented theory, so that nature becomes as ‘active’ an actor as people and community. Actor-network theory brings nature and society together, perceiving the two as mutually inclusive and constitutive. Coupled with recognition of power associated with political economic/ecological forces, actor-network theory can encourage us to see the frequency of tropical storms in Honduras as being among the powerful actors that have played a significant, consistent role in shaping the mode of ordering of impoverished Honduran peoples. This paper concludes by exploring how alternative, agroecological networks established in a protected area in southern Honduras with ‘strong’ natural actors can be re-ordered by incorporating autonomy and resiliency into the network.

    2005-06-15

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

    2003-01-01

    Full Text Available Great differences are encountered among Caucasus region countries with respect to energy resources reserves and economic conditions. Thermal power plants consist of obsolete and inefficient units, while the Soviet-type large heating systems in the area collapsed after 1992 and their reconstruction is considered uneconomic. Renovation needs of the power and heat sector, and the potential of Fluidised Bed Combustion implementations in decentralized cogeneration units were investigated, since operating oil and gas power plants exhibit high fuel consumption, low efficiency and poor environmental performance. Results showed significant prospects of Fluidised Bed Combustion utilization in decentralized cogeneration units in the Caucausus region heat and power sector. Their introduction constitutes an economically attractive way to cover power and heat demands and promotes utilization of domestic energy resources in all of three countries, provided that financial difficulties could be confronted.

    2009-08-01

    Full Text Available Actor-network theory and the analysis of technoscience developed by Javier Echeverría (2003 have many features in common, but they also diverge in a number of points. While the analysis of technoscience amounts to the attempt of classifying and characterizing the modalities of contemporary scientific and technological practices, the set of methodological tools of actor-network theory brings to the forefront the disorder hidden behind the ordered image of both contemporary and past technoscience. However, actor-network theory may be useful to describe the complex networks woven by research centres, institutions, universities, and companies, and their products in terms of natural and social order. In this paper, we characterize actor-network theory as well as technoscience and we identify how both, in spite of their differences, might benefit each other.La teoría del actor-red y el análisis de la tecnociencia desarrollado por Javier Echeverría (2003 presentan múltiples puntos comunes, pero también importantes divergencias. Mientras que el análisis de la tecnociencia responde al intento filosófico de clasificar y caracterizar las modalidades de práctica científico-tecnológica contemporánea, el conjunto de herramientas metodológicas de la teoría del actor-red trae al primer plano el desorden oculto tras la ordenada apariencia de la tecnociencia, la contemporánea y la de épocas pasadas. Sin embargo, la teoría del actor-red se muestra útil para describir las complejas redes tejidas por centros de investigación, instituciones, universidades y empresas, y los productos resultantes de las mismas en términos de orden natural y social. En este trabajo caracterizamos someramente tanto la teoría del actorred como la tecnociencia, para identificar de qué modo ambas, pese a sus diferencias, pueden beneficiarse mutuamente.

    Saltman, Richard B; Bankauskaite, Vaida

    2006-04-01

    Although decentralization has been widely implemented in health systems, there is little agreement as to how it should be defined or the outcomes it should produce. This article develops a functional typology based on political, administrative, and fiscal dimensions of decentralization. It utilizes these three categories to identify and highlight key theoretical issues concerning decentralization, emphasizing the likely advantages and disadvantages that decentralization can be expected to generate. It then examines the usefulness of this functional framework in explaining recent policy-making decisions within a number of tax-based health systems in Western Europe. The article concludes by suggesting that this three-part typology can be helpful to both policy makers and academics in evaluating the effectiveness of decentralization as a policy mechanism within health care systems.

    Full Text Available Most of the developing nations are still struggling for efficient use of their resources. In order to overcome physical and administrative constraints of the development, it is necessary to transfer the power from the central government to local authorities. Distribution of power from improves the management of resources and community participation which is considered key to sustainable development. Advocates of decentralization argue that decentralized government is source to improve community participation in rural development. Decentralized government is considered more responsive towards local needs and development of poor peoples. There are many obstacles to expand the citizen participation in rural areas. There are many approaches for participatory development but all have to face the same challenges. Current paper highlights the literature about Decentralization and participatory rural development. Concept and modalities of Decentralization, dimensions of participation, types of rural participation and obstacles to participation are also the part of this paper.

    1986-01-01

    Methods arising from the area of decentralized control are emerging for analysis and control synthesis for large flexible structures. In this paper the control strategy involves a decentralized model reference adaptive approach using a variable structure control. Local models are formulated based on desired damping and response time in a model-following scheme for various modal configurations. Variable structure controllers are then designed employing co-located angular rate and position feedback. In this scheme local control forces the system to move on a local sliding mode in some local error space. An important feature of this approach is that the local subsystem is made insensitive to dynamical interactions with other subsystems once the sliding surface is reached. Experiments based on the above have been performed for NASA's flexible grid experimental apparatus. The grid is designed to admit appreciable low-frequency structural dynamics, and allows for implementation of distributed computing components, inertial sensors, and actuation devices. A finite-element analysis of the grid provides the model for control system design and simulation; results of several simulations are reported on here, and a discussion of application experiments on the apparatus is presented.

  10. Batch Delivery Scheduling with Multiple Decentralized Manufacturers

    2014-01-01

    Full Text Available This paper addresses an integrated decision on production scheduling and delivery operations, which is one of the most important issues in supply chain scheduling. We study a model in which a set of jobs ordered by only one customer and a set of decentralized manufacturers located at different locations are considered. Specifically, each job must be assigned to one of the decentralized manufacturers to process on its single machine facility. Then, the job is delivered to the customer directly in batch without intermediate inventory. The objective is to find a joint schedule of production and distribution to optimize the customer service level and delivery cost. In our work, we discuss this problem considering two different situations in terms of the customer service level. In the first one, the customer service is measured by the maximum arrival time, while the customer service is measured by the total arrival time in the second one. For each situation, we develop a dynamic programming algorithm to solve, respectively. Moreover, we identify a special case for the latter situation by introducing its corresponding solutions.

  11. Decentralized asset management for collaborative sensing

    Malhotra, Raj P.; Pribilski, Michael J.; Toole, Patrick A.; Agate, Craig

    2017-05-01

    There has been increased impetus to leverage Small Unmanned Aerial Systems (SUAS) for collaborative sensing applications in which many platforms work together to provide critical situation awareness in dynamic environments. Such applications require critical sensor observations to be made at the right place and time to facilitate the detection, tracking, and classification of ground-based objects. This further requires rapid response to real-world events and the balancing of multiple, competing mission objectives. In this context, human operators become overwhelmed with management of many platforms. Further, current automated planning paradigms tend to be centralized and don't scale up well to many collaborating platforms. We introduce a decentralized approach based upon information-theory and distributed fusion which enable us to scale up to large numbers of collaborating Small Unmanned Aerial Systems (SUAS) platforms. This is exercised against a military application involving the autonomous detection, tracking, and classification of critical mobile targets. We further show that, based upon monte-carlo simulation results, our decentralized approach out-performs more static management strategies employed by human operators and achieves similar results to a centralized approach while being scalable and robust to degradation of communication. Finally, we describe the limitations of our approach and future directions for our research.

  12. Centralized versus decentralized lunar PMAD study

    Science.gov (United States)

    Metcalf, Kenneth J.

    A study of proposed lunar base architectures was performed to identify issues concerning centralized and decentralized power system deployment options. The power management and distribution (PMAD) system analysis is addressed. The PMAD system consists of power conditioning components that convert the generated power into the form desired for transmission, transmission lines that conduct this power from the power sources to the loads, and power conditioning hardware that converts the power into the form selected for secondary distribution to the loads. Three PMAD architecture configurations were evaluated: centralized, hybrid, and decentralized. Two models were created for each architecture to identify the preferred method of power transmission, DC or AC. Each model permitted the load power demands and distribution voltage level to be varied to assess the impact on power system mass. The AC power system models also allowed the distribution frequency to be changed. Finally, individual models were developed for different transmission line configurations and placements to determine the best conductor construction and installation location.

    The results of a study of proposed lunar base architectures to identify issues concerning centralized and decentralized power system deployment options are presented. The power system consists of the energy producing system (power plant), the power conditioning components used to convert the generated power into the form desired for transmission, the transmission lines that conduct this power from the power sources to the loads, and the primary power conditioning hardware located at the user end. Three power system architectures, centralized, hybrid, and decentralized, were evaluated during the course of this study. Candidate power sources were characterized with respect to mass and radiator area. Two electrical models were created for each architecture to identify the preferred method of power transmission, dc or ac. Each model allowed the transmission voltage level to be varied at assess the impact on power system mass. The ac power system models also permitted the transmission line configurations and placements to determine the best conductor construction and installation location. Key parameters used to evaluate each configuration were power source and power conditioning component efficiencies, masses, and radiator areas; transmission line masses and operating temperatures; and total system mass.

  15. A Method for Studying Social Actors

    2015-08-01

    Full Text Available So little agreement exists on what constitutes sociology that it seems impossible to de?ne its speci?c methods. We can however proceed through a series of eliminations. Light has been shed on many types of social behavior as economic studies have taken more interest in issues of social strati?cation and mobility or in consumer behavior, and as they increasingly incorporate elaborate quantitative analysis into this type of data. Correlations between social statuses and social behavior tell us about the logic of the system, yet not about that of the actors. Hence, we must imagine other methods in order to reach the actor as an autonomous being, as an agent of transformation of his environment and of his own situation, as a creator of imaginary worlds, as capable of referring to absolute values or of being involved in love relations.

  20. Fractional Power Control for Decentralized Wireless Networks

    CERN Document Server

    Jindal, Nihar; Andrews, Jeffrey G

    2007-01-01

    We propose and analyze a new paradigm for power control in decentralized wireless networks, termed fractional power control. Transmission power is chosen as the current channel quality raised to an exponent -s, where s is a constant between 0 and 1. Choosing s = 1 and s = 0 correspond to the familiar cases of channel inversion and constant power transmission, respectively. Choosing s in (0, 1) allows all intermediate policies between these two extremes to be evaluated, and we see that neither extreme is ideal. We prove that using an exponent of s = 1/2 optimizes the transmission capacity of an ad hoc network, meaning that the inverse square root of the channel strength is the optimal transmit power scaling. Intuitively, this choice achieves the optimal balance between helping disadvantaged users while making sure they do not flood the network with interference.

    Wu, Feng; Chen, Xiaoping

    2012-01-01

    We present decentralized rollout sampling policy iteration (DecRSPI) - a new algorithm for multi-agent decision problems formalized as DEC-POMDPs. DecRSPI is designed to improve scalability and tackle problems that lack an explicit model. The algorithm uses Monte- Carlo methods to generate a sample of reachable belief states. Then it computes a joint policy for each belief state based on the rollout estimations. A new policy representation allows us to represent solutions compactly. The key benefits of the algorithm are its linear time complexity over the number of agents, its bounded memory usage and good solution quality. It can solve larger problems that are intractable for existing planning algorithms. Experimental results confirm the effectiveness and scalability of the approach.

    Innovative approaches are needed to address the needs of the 1.3 billion people lacking electricity, while simultaneously transitioning to a decarbonized energy system. With particular focus on the energy needs of the underserved, we present an analytic and conceptual framework that clarifies the heterogeneous continuum of centralized on-grid electricity, autonomous mini- or community grids, and distributed, individual energy services. A historical analysis shows that the present day is a unique moment in the history of electrification where decentralized energy networks are rapidly spreading, based on super-efficient end-use appliances and low-cost photovoltaics. We document how this evolution is supported by critical and widely available information technologies, particularly mobile phones and virtual financial services. These disruptive technology systems can rapidly increase access to basic electricity services and directly inform the emerging Sustainable Development Goals for quality of life, while simultaneously driving action towards low-carbon, Earth-sustaining, inclusive energy systems.

Experiments were conducted on four groups of anesthetised, open-chest dogs (n = 32: 1- controls (CTR, intact cardiac nerves, 2- ischemic preconditioning (PC; 4 cycles of 5-min IR, 3- cardiac decentralization (CD and 4- CD+PC; all dogs underwent 60-min coronary occlusion and 180-min reperfusion. Coronary blood flow and reactive hyperemic responses were assessed using a blood volume flow probe. Infarct size (tetrazolium staining was related to anatomic area at risk and coronary collateral blood flow (microspheres in the anatomic area at risk. Post-ischemic reactive hyperemia and repayment-to-debt ratio responses were significantly reduced for all experimental groups; however, arterial perfusion pressure was not affected. Infarct size was reduced in CD dogs (18.6 ± 4.3; p = 0.001, data are mean ± 1 SD compared to 25.2 ± 5.5% in CTR dogs and was less in PC dogs as expected (13.5 ± 3.2 vs. 25.2 ± 5.5%; p = 0.001; after acute CD, PC protection was conserved (11.6 ± 3.4 vs. 18.6 ± 4.3%; p = 0.02. In conclusion, our findings provide strong evidence that myocardial protection against ischemic injury can be preserved independent of extrinsic cardiac nerve inputs.

    Decentralized control strategies for nonlinear systems are achieved via feedback linearization techniques. New results on optimization and parameter robustness of non-linear systems are also developed. In addition, parametric uncertainty in large-scale systems is handled by sensitivity analysis and optimal control methods in a completely decentralized framework. This idea is applied to alleviate uncertainty in friction parameters for the gimbal joints on Space Station Freedom. As an example of decentralized nonlinear control, singular perturbation methods and distributed vibration damping are merged into a control strategy for a two-link flexible manipulator.

    Robust synchronization (phase locking) of power plants and consumers centrally underlies the stable operation of electric power grids. Despite current attempts to control large-scale networks, even their uncontrolled collective dynamics is not fully understood. Here we analyze conditions enabling self-organized synchronization in oscillator networks that serve as coarse-scale models for power grids, focusing on decentralizing power sources. Intriguingly, we find that whereas more decentralized grids become more sensitive to dynamical perturbations, they simultaneously become more robust to topological failures. Decentralizing power sources may thus facilitate the onset of synchronization in modern power grids.

For the continuous case,the main improvement in the paper as compared with the corresponding results in the literature is to extend the considered class of systems from S to S*(both will be defined in the paper)without resulting in high decentralized gain and difficult numerical computation. The algorithm for obtaining decentralized state feedback control to stable the overall system is presented. The discrete case and some very useful results are discussed as well.

Sexual politics has become a critical battlefield when it comes to the role of religion in the Argentinean liberal-democratic regime, while gender and sexuality have been the main political targets of religious institutions since the 1980s and 1990s. In this context, progressive legislation on gender, sexual, and reproductive rights was passed, including same-sex marriage and the recognition of transgender identities, despite the opposition of the Catholic Church. Paradoxically, abortion remains largely illegal, allowed only in exceptional circumstances.

This insight allows analyzing neoliberal identification processes as heterogeneous trajectories with diverse geographic and temporal scopes.

  17. Integrating Decentralized Indoor Evacuation with Information Depositories in the Field

    Directory of Open Access Journals (Sweden)

    Haifeng Zhao

    2017-07-01

    Full Text Available The lonelier evacuees find themselves, the riskier become their wayfinding decisions. This research supports single evacuees in a dynamically changing environment with risk-aware guidance. It deploys the concept of decentralized evacuation, where evacuees are guided by smartphones acquiring environmental knowledge and risk information via exploration and knowledge sharing by peer-to-peer communication. Peer-to-peer communication, however, relies on the chance that people come into communication range with each other. This chance can be low. To bridge between people being not at the same time at the same places, this paper suggests information depositories at strategic locations to improve information sharing. Information depositories collect the knowledge acquired by the smartphones of evacuees passing by, maintain this information, and convey it to other passing-by evacuees. Multi-agent simulation implementing these depositories in an indoor environment shows that integrating depositories improves evacuation performance: It enhances the risk awareness and consequently increases the chance that people survive and reduces their evacuation time. For evacuating dynamic events, deploying depositories at staircases has been shown more effective than deploying them in corridors.

    2015-12-01

    This paper builds on the assumption that an effective approach to support the sustainability of natural resource management initiatives is institutional "bricolage." We argue that participatory planning processes can foster institutional bricolage by encouraging stakeholders to make their own arrangements based on the hybridization of old and new institutions. This papers aims at identifying how participatory process facilitators can encourage institutional bricolage. Specifically the paper investigates the specific contextual and procedural drivers of institutional dynamics in two case studies: the Rwenzori region in Uganda and the Fogera woreda in Ethiopia. In both cases, participatory planning processes were implemented. This research has three innovative aspects. First, it establishes a clear distinction between six terms which are useful for identifying, describing, and analyzing institutional dynamics: formal and informal; institutions and organizations; and emergence and change. Secondly, it compares the contrasting institutional dynamics in the two case studies. Thirdly, process-tracing is used to identify contextual and procedural drivers to institutional dynamics. We assume that procedural drivers can be used as "levers" by facilitators to trigger institutional bricolage. We found that facilitators need to pay particular attention to the institutional context in which the participatory planning process takes place, and especially at existing institutional gaps or failures. We identified three clusters of procedural levers: the selection and engagement of participants; the legitimacy, knowledge, and ideas of facilitators; and the design of the process, including the scale at which it is developed, the participatory tools used and the management of the diversity of frames.

In this paper we put forward a very simple idea: Actor-Network Theory was born with certain relevance in Social Sciences when it diffracted in a myriad of different uses and applications. The main corollary of such an idea is also straightforward: the very difference between Actor-Network Theory and other perspectives in Social Sciences resides in the permanent diaspora and transition of the former.

  20. Communication-Based Decomposition Mechanisms for Decentralized MDPs

    CERN Document Server

    Goldman, Claudia V; 10.1613/jair.2466

    2011-01-01

    Multi-agent planning in stochastic environments can be framed formally as a decentralized Markov decision problem. Many real-life distributed problems that arise in manufacturing, multi-robot coordination and information gathering scenarios can be formalized using this framework. However, finding the optimal solution in the general case is hard, limiting the applicability of recently developed algorithms. This paper provides a practical approach for solving decentralized control problems when communication among the decision makers is possible, but costly. We develop the notion of communication-based mechanism that allows us to decompose a decentralized MDP into multiple single-agent problems. In this framework, referred to as decentralized semi-Markov decision process with direct communication (Dec-SMDP-Com), agents operate separately between communications. We show that finding an optimal mechanism is equivalent to solving optimally a Dec-SMDP-Com. We also provide a heuristic search algorithm that converges...

  1. Decentralized control of large flexible structures by joint decoupling

    Science.gov (United States)

    Su, Tzu-Jeng; Juang, Jer-Nan

    1994-01-01

    This paper presents a novel method to design decentralized controllers for large complex flexible structures by using the idea of joint decoupling. Decoupling of joint degrees of freedom from the interior degrees of freedom is achieved by setting the joint actuator commands to cancel the internal forces exerting on the joint degrees of freedom. By doing so, the interactions between substructures are eliminated. The global structure control design problem is then decomposed into several substructure control design problems. Control commands for interior actuators are set to be localized state feedback using decentralized observers for state estimation. The proposed decentralized controllers can operate successfully at the individual substructure level as well as at the global structure level. Not only control design but also control implementation is decentralized. A two-component mass-spring-damper system is used as an example to demonstrate the proposed method.

    2008-01-01

    Peer-to-peer systems are evolving with new information-system architectures, leading to the idea that the principles of decentralization and self-organization will offer new approaches in informatics, especially for systems that scale with the number of users or for which central authorities do not prevail. This book describes a new way of building global agreements (semantic interoperability) based only on decentralized, self-organizing interactions.

    The Sendai Framework, which outlines the global course on disaster risk reduction until 2030, places strong importance on the role of local government in disaster risk reduction. An aim of decentralization is to increase the influence and authority of local government in decision making. Yet, there is limited empirical evidence of the extent, character and effects of decentralization in current disaster risk reduction implementation, and of the barriers that are most critical to this. This paper evaluates decentralization in relation to disaster risk reduction in Indonesia, chosen for its recent actions to decentralize governance of DRR coupled with a high level of disaster risk. An analytical framework was developed to evaluate the various dimensions of decentralized disaster risk reduction, which necessitated the use of a desk study, semi-structured interviews and a gap analysis. Key barriers to implementation in Indonesia included: capacity gaps at lower institutional levels, low compliance with legislation, disconnected policies, issues in communication and coordination and inadequate resourcing. However, any of these barriers are not unique to disaster risk reduction, and similar barriers have been observed for decentralization in other developing countries in other public sectors.

    Systems for large-scale reuse of electronic health record data is claimed to have the potential to transform the current health care delivery system. In principle three alternative solutions for reuse exist: centralized, data warehouse, and decentralized solutions. This chapter focuses on the decentralized system alternative. Decentralized systems may be categorized into approaches that move data to enable computations or move computations to the where data is located to enable computations. We describe a system that moves computations to where the data is located. Only this kind of decentralized solution has the capabilities to become ideal systems for reuse as the decentralized alternative enables computation and reuse of electronic health record data without moving or exposing the information to outsiders. This chapter describes the Snow system, which is a decentralized medical data processing system, its components and how it has been used. It also describes the requirements this kind of systems need to support to become sustainable and successful in recruiting voluntary participation from health institutions.

    Full Text Available The general purpose of this study is to thoroughly examine decentralization in education according to the literature and previous research, and to discuss the applicability of educational decentralization practices in Turkey. The literature was reviewed for the study and findings reported. It has been observed that decentralization in education practices were realized in many countries after the 1980’s. It is obvious that the educational system in Turkey has difficulty in meeting the needs, and encounters many problems due to its present centralist state. Educational decentralization can provide effective solutions for stakeholder engagement, educational financing and for problems in decision making and operation within the education system. However, the present state of local governments, the legal framework, geographical, cultural and social features indicate that Turkey’s conditions are not ready for decentralization in education. A decentralization model realized in the long run according to Turkey’s conditions, and as a result of a social consensus, can help resolve the problems of the Turkish education system.

    To assess the educational value of improvisational actors in difficult conversation simulations to teach communication and relational skills to interprofessional learners. Surveys of 192 interprofessional health care professionals, and 33 teaching faculty, and semi-structured interviews of 10 actors. Descriptive statistics, Fisher's exact test and chi-square test were used for quantitative analyses, and the Crabtree and Miller approach was used for qualitative analyses. 191/192 (99.5%) interprofessional learners (L), and 31/33 (94%) teaching faculty (F) responded to surveys. All 10/10 actors completed interviews. Nearly all participants found the actors realistic (98%L, 96%F), and valuable to the learning (97%L, 100%F). Most felt that role-play with another clinician would not have been as valuable as learning with actors (80%L, 97%F). There were no statistically significant differences in perceived value between learners who participated in the simulations (47%) versus those who observed (53%), or between doctors, nurses, or psychosocial professionals. Qualitative assessment yielded five actor value themes: Realism, Actor Feedback, Layperson Perspective, Depth of Emotion, and Role of Improvisation in Education. Actors independently identified similar themes as goals of their work. The value attributed to actors was nearly universal among interprofessional learners and faculty, and independent of enactment participation versus observation. Authenticity, feedback from actors, patient/family perspectives, emotion, and improvisation were key educational elements. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

  17. Bandwidth Partitioning in Decentralized Wireless Networks

    CERN Document Server

    Jindal, Nihar; Weber, Steven

    2007-01-01

    This paper addresses the following question, which is of interest in the design of a multiuser decentralized network. Given a total system bandwidth of W Hz and a fixed data rate constraint of R bps for each transmission, how many frequency slots N of size W/N should the band be partitioned into in order to maximize the number of simultaneous links in the network? Dividing the available spectrum results in two competing effects. On the positive side, a larger N allows for more parallel, non-interfering communications to take place in the same area. On the negative side, a larger N increases the SINR requirement for each link because the same information rate must be achieved over less bandwidth, which in turn increases the area consumed by each transmission. Exploring this tradeoff and determining the optimum value of N in terms of the system parameters is the focus of the paper. Using stochastic geometry, the optimal SINR threshold - which directly corresponds to the optimal spectral efficiency - is derived ...

  18. Decentralized provenance-aware publishing with nanopublications

    Directory of Open Access Journals (Sweden)

    Tobias Kuhn

    2016-08-01

    Full Text Available Publication and archival of scientific results is still commonly considered the responsability of classical publishing companies. Classical forms of publishing, however, which center around printed narrative articles, no longer seem well-suited in the digital age. In particular, there exist currently no efficient, reliable, and agreed-upon methods for publishing scientific datasets, which have become increasingly important for science. In this article, we propose to design scientific data publishing as a web-based bottom-up process, without top-down control of central authorities such as publishing companies. Based on a novel combination of existing concepts and technologies, we present a server network to decentrally store and archive data in the form of nanopublications, an RDF-based format to represent scientific data. We show how this approach allows researchers to publish, retrieve, verify, and recombine datasets of nanopublications in a reliable and trustworthy manner, and we argue that this architecture could be used as a low-level data publication layer to serve the Semantic Web in general. Our evaluation of the current network shows that this system is efficient and reliable.

  19. Establishing trust in decentralized smart sensor networks

    2011-06-01

    Smart sensors can gather all kind of information and process it. Cameras are still dominating and smart cameras can offer services for face recognition or person tracking. Operators are building collaborations to cover a larger area, to save costs and to add more and different sensors. Cryptographic methods may achieve integrity and confidentiality between operators, but not trust. Even if a partner or one of his sensors is authenticated, no statements can be made about the quality of the sensor data. Hence, trust must be established between the partners and their sensors. Trust can be built based on past experience. A reputation system collects opinions of operators about the behavior of sensors and calculates trust based on these opinions. Many reputation systems have been proposed, e.g., for authentication of files in peer-topeer networks. This work presents a new reputation system, which is designed to calculate the trustworthiness of smart sensors and smart sensor systems. A new trust model, including functions to calculate and update trust on past experiences, is proposed. When fusing information of multiple sensors, it cannot always be reconstructed, which information led to a bad result. Hence, an approach for fair rating is shown. The proposed system has been realized in a Service-Oriented Architecture for easy integration in existing smart sensor systems, e.g., smart surveillance systems. The model itself can be used in every decentralized heterogeneous smart sensor network.

  20. Platform Architecture for Decentralized Positioning Systems

    Zakaria Kasmi

    2017-04-01

    Full Text Available A platform architecture for positioning systems is essential for the realization of a flexible localization system, which interacts with other systems and supports various positioning technologies and algorithms. The decentralized processing of a position enables pushing the application-level knowledge into a mobile station and avoids the communication with a central unit such as a server or a base station. In addition, the calculation of the position on low-cost and resource-constrained devices presents a challenge due to the limited computing, storage capacity, as well as power supply. Therefore, we propose a platform architecture that enables the design of a system with the reusability of the components, extensibility (e.g., with other positioning technologies and interoperability. Furthermore, the position is computed on a low-cost device such as a microcontroller, which simultaneously performs additional tasks such as data collecting or preprocessing based on an operating system. The platform architecture is designed, implemented and evaluated on the basis of two positioning systems: a field strength system and a time of arrival-based positioning system.

  1. The Value of Feedback in Decentralized Detection

    Tay, Wee Peng

    2011-01-01

    We consider the decentralized binary hypothesis testing problem in networks with feedback, where some or all of the sensors have access to compressed summaries of other sensors' observations. We study certain two-message feedback architectures, in which every sensor sends two messages to a fusion center, with the second message based on full or partial knowledge of the first messages of the other sensors. We also study one-message feedback architectures, in which each sensor sends one message to a fusion center, with a group of sensors having full or partial knowledge of the messages from the sensors not in that group. Under either a Neyman-Pearson or a Bayesian formulation, we show that the asymptotically optimal (in the limit of a large number of sensors) detection performance (as quantified by error exponents) does not benefit from the feedback messages, if the fusion center remembers all sensor messages. However, feedback can improve the Bayesian detection performance in the one-message feedback architect...

  2. Decentralized adaptive fuzzy control of robot manipulators.

    Science.gov (United States)

    Jin, Y

    1998-01-01

    This paper develops a decentralized adaptive fuzzy control scheme for robot manipulators via a combination of genetic algorithm and gradient method. The controller for each link consists of a feedforward fuzzy torque-computing system and a feedback fuzzy PD system. The feedforward fuzzy system is trained and optimized off-line by an improved genetic algorithm, that is to say, not only the parameters but also the structure of the fuzzy system are self-organized. Because genetic algorithm can operate successfully without the system model, no exact inverse dynamics of the robot system are required. The feedback fuzzy PD system, on the other hand, is tuned on-line using gradient method. In this way, the proportional and derivative gains are adjusted properly to keep the closed-loop system stable. The proposed controller has the following merits: (1) it needs no exact dynamics of the robot systems and the computation is time-saving because of the simple structure of the fuzzy systems; and (2) the controller is insensitive to various dynamics and payload uncertainties in robot systems. These are demonstrated by analyses of the computational complexity and various computer simulations.

  3. mSCTP Based Decentralized Mobility Framework

    2011-09-01

    Full Text Available To conceive the full potential of wireless IP services, Mobile Nodes (MNs must be able to roam seamlessly across different networks. Mobile Stream Control Transmission Protocol (mSCTP is a transport layer solution, which unlike Mobile IP (MIP, provides seamless mobility with minimum delay and negligible packet loss. However, mSCTP fails to locate the current IP address of the mobile node when Correspondent Node (CN wants to initiate a session. In this paper, we propose DHT Chord to provide the required location management. Chord is a P2P algorithm, which can efficiently provide the IP address of the called MN by using its key-value mapping. The proposed decentralized mobility framework collectively exploits the multihoming feature of mSCTP, and efficient key-value mapping of chord to provide seamless mobility. Suitability of the framework is analyzed by preliminary analysis of chord lookup efficiency, and mSCTP handover procedure using overlay weaver and NS-2. Performance analysis shows that mSCTP multihoming feature and Chord efficient key-value mapping can provide a non-delayed, reliable, and an efficient IP handover solution.

  7. Comparative LCA of decentralized wastewater treatment alternatives for non-potable urban reuse.

    2016-11-01

    Municipal wastewater (WW) effluent represents a reliable and significant source for reclaimed water, very much needed nowadays. Water reclamation and reuse has become an attractive option for conserving and extending available water sources. The decentralized approach to domestic WW treatment benefits from the advantages of source separation, which makes available simple small-scale systems and on-site reuse, which can be constructed on a short time schedule and occasionally upgraded with new technological developments. In this study we perform a Life Cycle Assessment to compare between the environmental impacts of four alternatives for a hypothetical city's water-wastewater service system. The baseline alternative is the most common, centralized approach for WW treatment, in which WW is conveyed to and treated in a large wastewater treatment plant (WWTP) and is then discharged to a stream. The three alternatives represent different scales of distribution of the WW treatment phase, along with urban irrigation and domestic non-potable water reuse (toilet flushing). The first alternative includes centralized treatment at a WWTP, with part of the reclaimed WW (RWW) supplied back to the urban consumers. The second and third alternatives implement de-centralized greywater (GW) treatment with local reuse, one at cluster level (320 households) and one at building level (40 households). Life cycle impact assessment results show a consistent disadvantage of the prevailing centralized approach under local conditions in Israel, where seawater desalination is the marginal source of water supply. The alternative of source separation and GW reuse at cluster level seems to be the most preferable one, though its environmental performance is only slightly better than GW reuse at building level. Centralized WW treatment with urban reuse of WWTP effluents is not advantageous over decentralized treatment of GW because the supply of RWW back to consumers is very costly in materials and

    It is well known that facial beauty is dictated by facial type, and harmony between the eyes, nose, and mouth. Furthermore, facial impression is judged according to the overall facial contour and the relationship between the facial structures. The aims of the present study were to determine the optimal criteria for the assessment of gathering or separation of the facial structures and to define standardized ratios for centralization or decentralization of the facial structures.Four different lengths were measured, and 2 indexes were calculated from standardized photographs of 551 volunteers. Centralization and decentralization were assessed using the width index (interpupillary distance / facial width) and height index (eyes-mouth distance / facial height). The mean ranges of the width index and height index were 42.0 to 45.0 and 36.0 to 39.0, respectively. The width index did not differ with sex, but males had more decentralized faces, and females had more centralized faces, vertically. The incidence rate of decentralized faces among the men was 30.3%, and that of centralized faces among the women was 25.2%.The mean ranges in width and height indexes have been determined in a Korean population. Faces with width and height index scores under and over the median ranges are determined to be "centralized" and "decentralized," respectively.

    To alleviate poverty and enhance conservation in resource dependent communities, managers must identify existing livelihood strategies and the associated factors that impede household access to livelihood assets. Researchers increasingly advocate reallocating management power from exclusionary central institutions to a decentralized system of management based on local and inclusive participation. However, it is yet to be shown if decentralizing conservation leads to diversified livelihoods within a protected area. The purpose of this study was to identify and assess factors affecting household livelihood diversification within Nepal's Kanchenjunga Conservation Area Project, the first protected area in Asia to decentralize conservation. We randomly surveyed 25% of Kanchenjunga households to assess household socioeconomic and demographic characteristics and access to livelihood assets. We used a cluster analysis with the ten most common income generating activities (both on- and off-farm) to group the strategies households use to diversify livelihoods, and a multinomial logistic regression to identify predictors of livelihood diversification. We found four distinct groups of household livelihood strategies with a range of diversification that directly corresponded to household income. The predictors of livelihood diversification were more related to pre-existing socioeconomic and demographic factors (e.g., more landholdings and livestock, fewer dependents, receiving remittances) than activities sponsored by decentralizing conservation (e.g., microcredit, training, education, interaction with project staff). Taken together, our findings indicate that without direct policies to target marginalized groups, decentralized conservation in Kanchenjunga will continue to exclude marginalized groups, limiting a household's ability to diversify their livelihood and perpetuating their dependence on natural resources.

    2008-02-15

    A reverse logistics system is a network of transportation logistics and processing functions that collect, consolidate, refurbish, and demanufacture end-of-life products. This paper examines centralized and decentralized models of decision-making for material flows and associated transaction prices in reverse logistics networks. We compare the application of a centralized model for planning reverse production systems, where a single planner is acquainted with all of the system information and has the authority to determine decision variables for the entire system, to a decentralized approach. In the decentralized approach, the entities coordinate between tiers of the system using a parametrized flow function and compete within tiers based on reaching a price equilibrium. We numerically demonstrate the increase in the total net profit of the centralized system relative to the decentralized one. This implies that one may overestimate the system material flows and profit if the system planner utilizes a centralized viewto predict behaviors of independent entities in the system and that decentralized contract mechanisms will require careful design to avoid losses in the efficiency and scope of these systems.

    The new mental health care policy, which has been set up in France, involves a change of paradigm, which has been going on since the 2000s: the emphasis is shifting from psychiatry to mental health care. This shift mainly concerns the knowledge about mental health is produced and circulates among an increasingly large number of bodies. Mainly grounded on actor interview analysis, official reports and blueprints, this study shows that the results of this process are numerous. They include the development of ambulatory care and strong moves towards decentralization. More data and knowledge are therefore to be shared in this more complex system. However, the French State, in the form of the central administration, is taking advantage of this move and is still contributing significantly to the definition and implementation of the new policy. On the other hand, the new governance dynamic is not leading to standardization of medical practices, as the mental health field remains highly heterogeneous.

    Translating national policies and guidelines into effective action at the subnational level (e.g., province or region) is a prerequisite for ensuring an impact on nutrition. In several countries, including Vietnam, the focus of this paper, this process is affected by the quality of the decentralized process of planning and action. This study examined how provincial planning processes for nutrition occurred in Vietnam during 2009 and 2010. Key goals were to understand variability in processes across provinces, identify factors that influenced the process, and assess the usefulness of the process for individuals involved in planning and action. A qualitative case-study methodology was used. Data were drawn from interviews with 51 government officials in eight provinces. The study found little variability in the planning process among these eight provinces, probably due to a planning process that was predominantly a fiscal exercise within the confines of a largely centralized structure. Respondents were almost unanimous about the main barriers: a top-down approach to planning, limited human capacity for effective planning at subnational levels, and difficulty in integrating actions from multiple sectors. Provincial-level actors were deeply dissatisfied with the nature of their role in the process. Despite the rhetoric to the contrary, too much power is probably still retained at the central level. A strategic multiyear approach is needed to strengthen the provincial planning process and address many of the key barriers identified in this study.

  19. Review of legal and institutional issues in the use of decentralized solar energy systems

    The legal and institutional issues involved in the use of decentralized solar energy systems are examined for the purpose of advising government planners and policymakers, the solar industry, solar researchers, and prospective solar users of present and potential impediments and incentives to solar commercialization. This information was gathered primarily through a comprehensive literature review, with supplementary data provided through interviews with representatives of organizations active in the solar field. Five major issue areas were identified in the course of this study: (1) prohibitions on the use of solar equipment, (2) regulation of the production and placement of solar systems, (3) access to sunlight, (4) financial incentives and impediments to the use of solar technologies, and (5) the public utility-solar user interface. Each can be important in its impacts on the incidence of solar usage. The major actors involved with the issues identified above represent both the private and public sectors. Important private sector participants include solar manufacturers and installers, labor unions, lending institutions, utility companies, solar users themselves, and other community property owners. In the public sector, local, state, and federal governments are all capable of acting in ways that can influence the solar commercialization effort. Implementation options are available for all levels of government seeking to take an active role in addressing the previously mentioned legal and institutional issues. The appropriate actions will vary from federal to state to local governments, but each level can be important in removing existing barriers and creating new incentives for solar use.

  20. Decentralizing Governance of Agropastoral Systems in Kyrgyzstan: An Assessment of Recent Pasture Reforms

    2016-02-01

    Full Text Available Agropastoral systems in Kyrgyzstan have undergone dramatic change in recent decades. In large part, change has resulted from the introduction of legislation that devolves authority and responsibility for the management of common-pool agropastoral resources to community-level pasture users associations. By applying Ostrom’s principles of common resource governance, this paper analyzes the institutions and norms that currently shape local management practices in rural areas of Naryn Province in Kyrgyzstan and the views of different actors on pasture governance, including points of disagreement. Our research and analysis reveal that the community-initiated and -owned systems of pasture governance that were expected to develop and mature under the new Pasture Law have not yet been entirely realized. Decentralization occurred without the participation or awareness of most local resource users. As a consequence, users are creating and reinforcing their own community-defined practices and internal rules, leaving official management plans largely ignored and unenforced. Resource users tend to perceive the government-sanctioned pasture users associations not as public or democratic organizations that represent their interests, but rather as agencies that aim primarily to control the use of resources, exclude some people from decision-making, or impose taxation. Sustainable management of pasturelands therefore may best be served when community perspectives are more suitably integrated—from the planning phase through to collaborative governance and implementation of locally agreed upon management options.

  1. A Critical Look at Decentralized Personal Data Architectures

    2012-01-01

    While the Internet was conceived as a decentralized network, the most widely used web applications today tend toward centralization. Control increasingly rests with centralized service providers who, as a consequence, have also amassed unprecedented amounts of data about the behaviors and personalities of individuals. Developers, regulators, and consumer advocates have looked to alternative decentralized architectures as the natural response to threats posed by these centralized services. The result has been a great variety of solutions that include personal data stores (PDS), infomediaries, Vendor Relationship Management (VRM) systems, and federated and distributed social networks. And yet, for all these efforts, decentralized personal data architectures have seen little adoption. This position paper attempts to account for these failures, challenging the accepted wisdom in the web community on the feasibility and desirability of these approaches. We start with a historical discussion of the development of v...

  2. Does Decentralized Leadership Influence the Performance of Czech Museums?

    Directory of Open Access Journals (Sweden)

    Plaček Michal

    2017-06-01

    Full Text Available This study tests whether decentralized leadership influences the efficiency of running selected cultural institutions, specifically museums in the Czech Republic. For the analysis, data from 2015 from 187 museums spread around the whole Czech Republic are used. The method for the evaluation of efficiency is data envelope analysis, and for identifying the influence of decentralized leadership, a regression analysis is used. Museums established by municipalities reach higher efficiency than museums established by regions and central government. The causes may be found in the ability to better estimate the local demand as well as in the rational behavior of municipalities that prefer a cost-minimization strategy. The benefits of decentralization cannot be seen only in the field of finance but also in reinforcing local traditions, trust and the effects of social capital that is generated by a strong regional cultural identity.

  3. The impulse influence function for de-centralized control

    2004-01-01

    Impulse influence matrix function is introduced based on that the de-centralized control analysis is analogous to the sub-structural analysis in structural mechanics. The static sub-structural analysis is analogous to the usual de-centralized control, whereas the dynamic sub-structural analysis corresponds to the de-centralized control theory. The reciprocal symmetry for the impulse influence matrix function is proved, and is solved by the precise integration method for time invariant system, giving the results up to computer precision. Based on the impulse influence functions of subsystems, the combination of subsystems can lead to a set of integral equations and be solved numerically. Numerical example demonstrates the effectiveness of the method.

  4. Robust decentralized controller design for UPFC using μ-synthesis

    Taher, Seyed Abbas; Akbari, Shahabeddin; Abdolalipour, Ali; Hematti, Reza

    2010-08-01

    In this paper a new method based on structured singular value ( μ-synthesis) is proposed for the robust decentralized unified power flow controller (UPFC) design. To achieve decentralization, using the Schauder fixed point theorem the synthesis and analysis of multi-input multi-output (MIMO) control system is transformed into a set of equivalent multi-input single-output (MISO) control system. To cope with power system uncertainties μ-synthesis technique is being used for designing of UPFC controllers. The proposed μ-based controller has a decentralized scheme which has the advantage of reduction in the controller complexity and suitability for practical implementation. The effectiveness of the proposed control strategy on damping low frequency oscillations is evaluated under different operating conditions and compared with the conventional controller to demonstrate its robust performance through nonlinear simulation and some performance indices.

    2008-08-01

    This paper contains the second part of a study on a smart panel with five decentralized velocity feedback control units using proof mass electrodynamic actuators [Gonzalez Diaz et al., J. Acoust. Soc. Am. 124, 886 (2008)]. The implementation of five decentralized control loops is analyzed, both theoretically and experimentally. The stability properties of the five decentralized control units have been assessed with the generalized Nyquist criterion by plotting the loci of the eigenvalues of the fully populated matrix of frequency response functions between the five error signals and five input signals to the amplifiers driving the actuators. The control performance properties have been assessed in terms of the spatially averaged response of the panel measured with a scanning laser vibrometer and the total sound power radiated measured in an anechoic room. The two analyses have shown that reductions of up to 10 dB in both vibration response and sound radiation are measured at low audio frequencies, below about 250 Hz.

    2017-09-01

    We present a decentralized control strategy that yields switch interleaving among parallel connected dc-dc buck converters without communication. The proposed method is based on the digital implementation of the dynamics of a nonlinear oscillator circuit as the controller. Each controller is fully decentralized, i.e., it only requires the locally measured output current to synthesize the pulse width modulation (PWM) carrier waveform. By virtue of the intrinsic electrical coupling between converters, the nonlinear oscillator-based controllers converge to an interleaved state with uniform phase-spacing across PWM carriers. To the knowledge of the authors, this work represents the first fully decentralized strategy for switch interleaving of paralleled dc-dc buck converters.

    Decentralized wastewater treatment is the key to sustainable water management because it facilitates effluent (and nutrient) reuse for irrigation or as service water in households. Membrane bioreactors (MBR) can produce effluents of bathing water quality. Septic tanks can be retrofitted to MBR units. Package MBR plants for wastewater or grey water treatment are also available. Systems for decentralized treatment and reuse of domestic wastewater or grey water are also feasible for hotels, condominiums and apartment or office complexes. This paper presents the effluent qualities of different decentralized MBR applications. The high effluent quality allows infiltration even in sensitive areas or reuse for irrigation, toilet flushing and cleaning proposes in households. Due to the reusability of treated water and the possibility to design the systems for carbon reduction only, these systems can ideally and easily serve to close water and nutrient loops.

    The aim of this study has been the decentralization of multimedia content in a heterogeneous environment. The environment consisted of the research networks connecting the European Organization for Nuclear Research and the Finnish University and Research Network. The European Organization for Nuclear Research produces multimedia content which can be used as studying material all over the world. The Web University pilot in the European Organization for Nuclear Research has been developing a multimedia content delivery service for years. Delivering the multimedia content requires plenty of capacity from the network infrastructure. Different content of the material can have different demands for the network. In a heterogeneous environment, like the Internet, fulfilling all the demands can be a problem. Several methods exist to improve the situation. Decentralization of the content is one of the most popular solutions. Mirroring and caching are the main methods for decentralization. Recently developed content del...

  10. The Bases of Federalism and Decentralization in Education

    Carlos Ornelas

    2003-05-01

    Full Text Available This essay uses the Weberian-type ideal to define the conceptual bases of federalism and the decentralization of education. Classic federalism, ficticious federalism (corporativism, the origins and the indigenous version of the new federalism are discussed. We conclude that Mexican constitutional federalism is baroque and ambiguous. Based on theory and the experiences of various countries, bureaucratic centralism and its main characteristics are defined. As a contrast, a typology of educational decentralization is developed. Taken into account are its political, judicial and administrative definitions; a distinction is made between delegation and decentralization. It is argued that with the signing of the Agreement for the Modernization of Basic Education, the Mexican government sought to increase its legitimacy without losing control of education.

    Full Text Available This paper is an introduction to the monograph titled Diasporas and Transitions in the Actor-Network Theory. Drawing a parallel with ethnomethodology, its pages present the main features of this theory, a way to figure out its origins and a description of its present. The text ends with a brief look at the state of art of actor-network theory in Spain and an appraisal of a meeting titled Present and Future of Actor-Network Theory, which is the origin of our monograph. In this paper we put forward a very simple idea: Actor-Network Theory was born with certain relevance in Social Sciences when it diffracted in a myriad of different uses and applications. The main corollary of such an idea is also straightforward: the very difference between Actor-Network Theory and other perspectives in Social Sciences resides in the permanent diaspora and transition of the former.

    As product complexity and marketing competition increase, a collaborative product development is necessary for companies which develop high quality products in short lead-times. To support product actors from different fields, disciplines, and locations, wishing to exchange and share information, the representation of the actors' viewpoints is the underlying requirement of the collaborative product development. The actors' viewpoints approach was designed to provide an organisational framework following the actors' perspectives in the collaboration, and their relationships, could be explicitly gathered and formatted. The approach acknowledges the inevitability of multiple integration of product information as different views, promotes gathering of actors' interests, and encourages retrieved adequate information while providing support for integration through PLM and/or SCM collaboration. In this paper, a solution for neutral viewpoints representation is proposed. The product, process, and organisation informa...

  14. NGO - PRIVATE ACTORS AT AN INTERNATIONAL LEVEL

    2011-12-01

    Full Text Available International law, taken by globalization, helps emerge “private actors at an international level” by generating “a removal from territories of problems and solutions”. The question of NGO accessing international jurisdictions is situated at this intersection, which is a dangerous one for jurists. The ways of national laws intersect, in fact, with those of international law. More over, private international law, more specifically, the private judicial nature of NGOs that enter into contact with public international law, an intersection that will imprint a plural-disciplinary character that marks this study. Thus, we must follow this rocky road and try a private approach of a question disputed by public law, which is also a part of international law. The risks of maladroitness are numerous, but must be assumed according to their importance and of the rarity of clarification attempts. NGOs, legal persons from private law exercising their activities in international context contain, in fact, elements of foreign origin that result in specific problems of international law. And if “international law can not be the domain of perfect solutions” it can allow however the adoption of others which, that can seem less perfect to some, will possess the aptitude of “creating the laws of a state”. Thus, only by allying public international law to private law, the question of NGOs access to international jurisdictions can receive an answer.

    The climate change mitigation mechanism Reducing Emissions from Deforestation and Forest Degradation in developing countries (REDD+) is currently being negotiated under the United Nations Framework Convention on Climate Change (UNFCCC). Integrating biodiversity monitoring into REDD+ facilitates compliance with the safeguards stipulated by the UNFCCC to exclude environmental risks. Interviews with actors engaged in REDD+ implementation and biodiversity conservation at the national and sub-national level in Peru (n = 30) and a literature review (n = 58) were conducted to pinpoint constraints and opportunities for monitoring effects of REDD+ management interventions on biodiversity, and to identify relevant biodiversity data and indicators. It was found that particularly sub-national actors, who were frequently involved in REDD+ pilot projects, acknowledge the availability of biodiversity data. Actors at both the national and sub-national levels, however, criticized data gaps and data being scattered across biodiversity research organizations. Most of the literature reviewed (78 %) included indicators on the state of certain biodiversity aspects, especially mammals. Indicators for pressure on biodiversity, impacts on environmental functions, or policy responses to environmental threats were addressed less frequently (31, 21, and 10 %, respectively). Integrating biodiversity concerns in carbon monitoring schemes was considered to have potential, although few specific examples were identified. The involvement of biodiversity research organizations in sub-national REDD+ activities enhances monitoring capacities. It is discussed how improvements in collaboration among actors from the project to the national level could facilitate the evaluation of existing information at the national level. Monitoring changes in ecosystem services may increase the ecological and socioeconomic viability of REDD+.

    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.

    Full Text Available Along with the new economy, the competitive advantage of cities is now derived from management of their cultural productions. However, pottery making as cultural industry including ceramic and other earthenware products, currently suffers from many difficulties as inefficient role of government, environmental problems, and the lack of promotion and marketing strategies and falls behind the recent urban development trends. Menemen-Izmir/Turkey has been selected as case area, where the pottery making inherited for five generations. The aim of this study is to suggest a model to tackle with the current difficulties of and also to develop cultural production. The data have been collected via questionnaire and interviews with the pottery masters and Pottery Makers Association. The research proposes the multi actor-based approach through statistically analyses and maps to manage cultural industries and integrate various actors related to the cultural production into the decision making process of urban planning.

    Renewables will soon dominate energy production in our electric power system. And yet, how to integrate renewable energy into the grid and the market is still a subject of major debate. Decentral Smart Grid Control (DSGC) was recently proposed as a robust and decentralized approach to balance supply and demand and to guarantee a grid operation that is both economically and dynamically feasible. Here, we analyze the impact of network topology by assessing the stability of essential network motifs using both linear stability analysis and basin volume for delay systems. Our results indicate that if frequency measurements are averaged over sufficiently large time intervals, DSGC enhances the stability of extended power grid systems. We further investigate whether DSGC supports centralized and/or decentralized power production and find it to be applicable to both. However, our results on cycle-like systems suggest that DSGC favors systems with decentralized production. Here, lower line capacities and lower averaging times are required compared to those with centralized production.

  4. U-Form vs. M-Form: How to Understand Decision Autonomy Under Healthcare Decentralization?

    Science.gov (United States)

    Bustamante, Arturo Vargas

    2016-01-01

    For more than three decades healthcare decentralization has been promoted in developing countries as a way of improving the financing and delivery of public healthcare. Decision autonomy under healthcare decentralization would determine the role and scope of responsibility of local authorities. Jalal Mohammed, Nicola North, and Toni Ashton analyze decision autonomy within decentralized services in Fiji. They conclude that the narrow decision space allowed to local entities might have limited the benefits of decentralization on users and providers. To discuss the costs and benefits of healthcare decentralization this paper uses the U-form and M-form typology to further illustrate the role of decision autonomy under healthcare decentralization. This paper argues that when evaluating healthcare decentralization, it is important to determine whether the benefits from decentralization are greater than its costs. The U-form and M-form framework is proposed as a useful typology to evaluate different types of institutional arrangements under healthcare decentralization. Under this model, the more decentralized organizational form (M-form) is superior if the benefits from flexibility exceed the costs of duplication and the more centralized organizational form (U-form) is superior if the savings from economies of scale outweigh the costly decision-making process from the center to the regions. Budgetary and financial autonomy and effective mechanisms to maintain local governments accountable for their spending behavior are key decision autonomy variables that could sway the cost-benefit analysis of healthcare decentralization.

It is through it that we sought to recognize the ideas and concepts that coexist in everyday institutional life, by recovering the voice of sport institutions' actors - parents, leaders, trainers and teachers, practising and players-, and also by analyzing speeches and practices; those institutions' distinguishing forms of organization; the ways that diverse actors relate and the social forms acting on them. We investigated sport institutions with the purpose of tracking the senses and meaning that actors grant them, their organization and dynamics, the reasons for their behaviour, the principles and logics that shape them. We also analyzed the joints that link them to external macroinstitutions, their autonomy or dependency with regard to the latter, and their incidence on sport institutions' logics

    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.

    Full Text Available Long-term economic and environmental concerns have resulted in a great amount of research on renewable sources of biomass and bioenergy to replace fossil fuels in the past decades. Decentralized biogas technology is one of the most potential technologies of biomass and bioenergy by using agricultural waste materials (e.g., animal manure, crop straw and by-products from food industries as feedstocks. By-products from biogas production, called digestate, are nutrient rich which could potentially be reused as green fertilizers in agriculture, thereby providing a sustainable substitute for synthetic fertilizers for ecosystem farm. Thus, the biogas production of anaerobic digestion (AD is win-win option for livestock and crop producers to address issues of waste management and energy supply, and to avoid contamination of surface and ground waters and emissions of odors and greenhouse gases. In this paper, we review biogas production technology and then evaluate environmental effects of digestate used as fertilizer. Finally, we discuss issues of deployment of decentralized biogas technology for ecosystem farms. Economic and technological barriers still exist for large scale deployment of biogas technology. Two national scale deployments in China and Nepal showed that the operational status of biogas digesters is not optimal and up to 50% of plants are non-functional after a short operation period regardless of the social and economic factors. Main barriers are a wide variation of feedstocks and environmental conditions (e.g., temperature over space and time. It becomes clear that the experimental conditions of the pilot plants need to be adjusted and calibrated to the local feedstocks and climate. Also, more research needs to be done in cold fermentation technology.

    Full Text Available The identification of learning mechanisms for locomotion has been the subject of much researchfor 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 (LSTD based learning converges to the optimal solution quickly by using natural gradient and balancing exploration and exploitation. Futhermore, rather than using a traditional (designer-specified reward it uses a dynamic value function as a stability indicator (SI that adapts to the environment.The results obtained are analyzed and explained by using a novel DST embodied cognition approach. Learning to walk, from this perspective, is a process of integrating sensorimotor levels and value.

    2015-01-01

    This book introduces various coverage control problems for mobile sensor networks including barrier, sweep and blanket. Unlike many existing algorithms, all of the robotic sensor and actuator motion algorithms developed in the book are fully decentralized or distributed, computationally efficient, easily implementable in engineering practice and based only on information on the closest neighbours of each mobile sensor and actuator and local information about the environment. Moreover, the mobile robotic sensors have no prior information about the environment in which they operation. These various types of coverage problems have never been covered before by a single book in a systematic way. Another topic of this book is the study of mobile robotic sensor and actuator networks. Many modern engineering applications include the use of sensor and actuator networks to provide efficient and effective monitoring and control of industrial and environmental processes. Such mobile sensor and actuator networks are abl...

    The classical decentralized detection problem of finding the optimal decision rules at the sensor and fusion center, as well as variants that introduce physical channel impairments have been studied extensively in the literature. The deployment of WSNs in decentralized detection applications brings new challenges to the field. Protocols for different communication layers have to be co-designed to optimize the detection performance. In this paper, we consider the communication network design problem for a tree WSN. We pursue a system-level approach where a complete model for the system is developed that captures the interactions between different layers, as well as different sensor quality measures. For network optimization, we propose a hierarchical optimization algorithm that lends itself to the tree structure, requiring only local network information. The proposed design approach shows superior performance over several contentionless and contention-based network design approaches.

  1. Decentralized Disturbance Accommodation with Limited Plant Model Information

    Farokhi, F; Johansson, K H

    2011-01-01

    The design of optimal disturbance accommodation and servomechanism controllers with limited plant model information is considered in this paper. Their closed-loop performance are compared using a performance metric called competitive ratio which is the worst-case ratio of the cost of a given control design strategy to the cost of the optimal control design with full model information. It was recently shown that when it comes to designing optimal centralized or partially structured decentralized state-feedback controllers with limited model information, the best control design strategy in terms of competitive ratio is a static one. This is true even though the optimal structured decentralized state-feedback controller with full model information is dynamic. In this paper, we show that, in contrast, the best limited model information control design strategy for the disturbance accommodation problem gives a dynamic controller. We find an explicit minimizer of the competitive ratio and we show that it is undomina...

    This paper explores the following three propositions and their relationships: (1) that, in our pluralistic policymaking environment, we cannot solve our nation's energy problems unless we can reach agreement among a diverse group of interested parties about specific actions; (2) that, short of a manifest emergency, such a consensus is difficult to reach unless the scale of the decision-making unit is relatively small; and therefore (3) that one of the keys to an effective energy policy in the United states is to rely heavily on local and regional energy planning and decision-making. First, the paper reviews our problem of irresolution and its roots, and it summaries the policy options for resolving it. Then it explores one of those options, decentralized planning, in a little more detail. Finally, it offers some speculations about the viability of a decentralized approach to energy planninng.

    2016-01-01

    Recently, a range of novel and cost-effective engineered wetland technologies for decentralization practices of domestic wastewater treatment have been developed with ecological process modification, the use of functionalized plants, and advanced biofilm formation. However, selecting the one that can be more appreciated for on-site sanitation is still uncertain. This paper reviews the role of plants, media materials, microorganisms, and oxygen transfer in domestic wastewater purification through constructed wetlands (CWs). The effectiveness of traditional and recently developed CWs and the necessity of an induced biofilm attachment surface (BAS) in these systems for the treatment of domestic sewage are presented. This review also elucidates the idea of CWs for domestic wastewater characteristics highly stressed by total dissolved solids and the adaptive strategies in mitigating the cold climate impacts on their efficiencies. Further research needed to enhance the stability and sustainability of CWs is highlighted. By a more advanced investigation, BAS CWs can be specified as an ideal treatment process in decentralization.

A high order neural network (HONN is used to approximate a decentralized control law designed by the backstepping technique as applied to a block strict feedback form (BSFF. The weights for each neural network are adapted online by an extended Kalman filter training algorithm. The motion for each joint is controlled independently using only local angular position and velocity measurements. The stability analysis for the closed‐loop system via the Lyapunov approach is included. Finally, the real‐time results show the feasibility of the proposed control scheme using a robot manipulator.

    2011-01-01

    A multitude of privacy breaches, both accidental and malicious, have prompted users to distrust centralized providers of online social networks (OSNs) and investigate decentralized solutions. We examine the design of a fully decentralized (peer-to-peer) OSN, with a special focus on privacy and security. In particular, we wish to protect the confidentiality, integrity, and availability of user content and the privacy of user relationships. We propose DECENT, an architecture for OSNs that uses a distributed hash table to store user data, and features cryptographic protections for confidentiality and integrity, as well as support for flexible attribute policies and fast revocation. DECENT ensures that neither data nor social relationships are visible to unauthorized users and provides availability through replication and authentication of updates. We evaluate DECENT through simulation and experiments on the PlanetLab network and show that DECENT is able to replicate the main functionality of current centralized ...

  6. Learning Equilibria with Partial Information in Decentralized Wireless Networks

    CERN Document Server

    Rose, Luca; Lasaulce, Samson; Debbah, Mérouane

    2011-01-01

    In this article, a survey of several important equilibrium concepts for decentralized networks is presented. The term decentralized is used here to refer to scenarios where decisions (e.g., choosing a power allocation policy) are taken autonomously by devices interacting with each other (e.g., through mutual interference). The iterative long-term interaction is characterized by stable points of the wireless network called equilibria. The interest in these equilibria stems from the relevance of network stability and the fact that they can be achieved by letting radio devices to repeatedly interact over time. To achieve these equilibria, several learning techniques, namely, the best response dynamics, fictitious play, smoothed fictitious play, reinforcement learning algorithms, and regret matching, are discussed in terms of information requirements and convergence properties. Most of the notions introduced here, for both equilibria and learning schemes, are illustrated by a simple case study, namely, an interfe...

  7. Decentralized adaptive control designs and microstrip antennas for smart structures

    Science.gov (United States)

    Khorrami, Farshad; Jain, Sandeep; Das, Nirod K.

    1996-05-01

    Smart structures lend themselves naturally to a decentralized control design framework, especially with adaptation mechanisms. The main reason being that it is highly undesirable to connect all the sensors and actuators in a large structure to a central processor. It is rather desirable to have local decision-making at each smart patch. Furthermore, this local controllers should be easily `expandable' to `contractible.' This corresponds to the fact that addition/deletion of several smart patches should not require a total redesign of the control system. The decentralized control strategies advocated in this paper are of expandable/contractible type. On another front, we are considering utilization of micro-strip antennas for power transfer to and from smart structures. We have made preliminary contributions in this direction and further developments are underway. These approaches are being pursued for active vibration damping and noise cancellation via piezoelectric ceramics although the methodology is general enough to be applicable to other type of active structures.

    2000-07-01

    Decentralized ventilation systems may be the solution of the future. The article discusses how they can be economically attractive. They can also easily be designed to meet the needs of individual users. As an illustration, the article discusses a sixteen-floor office building with a canteen on the ground floor. Two cases are compared. In one case, four aggregates are installed in a technical room on the roof. These have rotary heat recovery, heating and refrigerating batteries, fans, dampers and filters. The cantina aggregate is placed in the basement, but of the same design as the other aggregates. The other case replaces the four aggregates of the first case with seventeen compact aggregates, one for each floor. They communicate through supervisory control. The decentralized system is found to be superior, although there are more aggregates to maintain.

Specifically, decentralized schemes are more flexible, less computationally intensive, and easier to implement without relying on communication......-load generation costs. Although the prioritization works well with some generation costs saved, its reliance on only the DG no-load generation costs does not allow it to operate well under certain conditions.

  13. An approach to decentralizing search, using stigmergic hyperlinks

    OpenAIRE

    Marques, Artur; Figueiredo,José

    2010-01-01

    A stigmergic hyperlink, or “stigh”, is an object that looks and behaves like a regular HTML hyperlink, but runs at the server side. A system of stighs displays interesting emergent behaviors, of some complexity, but a stigh alone is very simple: it has a life attribute, only reinforced when users click it, and methods to provide meta-information about its destination. We reason that stigmergic hyperlinks could support a more decentralized approach to the Web search problem, particularly for a...

This is natural, as on one hand, multiagent systems usually possess a structure that determines the allowable interactions among the agents; and on the other hand, the single most pressing need in a cooperative multiagent system is to coordinate the local policies of autonomous agents with restricted capabilities to serve a system-wide goal. The presence ...

  19. Game-Based Virtual Worlds as Decentralized Virtual Activity Systems

    Science.gov (United States)

    Scacchi, Walt

    There is widespread interest in the development and use of decentralized systems and virtual world environments as possible new places for engaging in collaborative work activities. Similarly, there is widespread interest in stimulating new technological innovations that enable people to come together through social networking, file/media sharing, and networked multi-player computer game play. A decentralized virtual activity system (DVAS) is a networked computer supported work/play system whose elements and social activities can be both virtual and decentralized (Scacchi et al. 2008b). Massively multi-player online games (MMOGs) such as World of Warcraft and online virtual worlds such as Second Life are each popular examples of a DVAS. Furthermore, these systems are beginning to be used for research, deve-lopment, and education activities in different science, technology, and engineering domains (Bainbridge 2007, Bohannon et al. 2009; Rieber 2005; Scacchi and Adams 2007; Shaffer 2006), which are also of interest here. This chapter explores two case studies of DVASs developed at the University of California at Irvine that employ game-based virtual worlds to support collaborative work/play activities in different settings. The settings include those that model and simulate practical or imaginative physical worlds in different domains of science, technology, or engineering through alternative virtual worlds where players/workers engage in different kinds of quests or quest-like workflows (Jakobsson 2006).

  20. The Multi-faceted Debate on Decentralization and Collective Welfare

    2010-12-01

    Full Text Available Studies on the relation between decentralization reforms and the performance of governments and their policies have presented a myriad of theoretical developments but inconclusive results on the empirically verifiable effects of these propositions. Many of the reviews carried out thus far in this field merely criticize these propositions without proposing alternatives for analysis. This article presents a review of this debate in a very specific way: it selects the propositions that points towards the causal factors explaining government’s responsiveness to its citizens. Four types of interpretations are discussed: 1 allocative efficiency theories of fiscal decentralization, 2 the multiple dimensions of decentralization, 3 the institutional design of reforms, and 4 the qualitative aspects of governance. Despite the observed divergences in the use of concepts, analytical preoccupations and in relation to the empirical operationalization of variables, this article points to a series of hypotheses that could be extracted from this debate and that could be the object of an empirical test.

  1. Evolutionary Concepts for Decentralized Air Traffic Flow Management

    Science.gov (United States)

    Adams, Milton; Kolitz, Stephan; Milner, Joseph; Odoni, Amedeo

    1997-01-01

    Alternative concepts for modifying the policies and procedures under which the air traffic flow management system operates are described, and an approach to the evaluation of those concepts is discussed. Here, air traffic flow management includes all activities related to the management of the flow of aircraft and related system resources from 'block to block.' The alternative concepts represent stages in the evolution from the current system, in which air traffic management decision making is largely centralized within the FAA, to a more decentralized approach wherein the airlines and other airspace users collaborate in air traffic management decision making with the FAA. The emphasis in the discussion is on a viable medium-term partially decentralized scenario representing a phase of this evolution that is consistent with the decision-making approaches embodied in proposed Free Flight concepts for air traffic management. System-level metrics for analyzing and evaluating the various alternatives are defined, and a simulation testbed developed to generate values for those metrics is described. The fundamental issue of modeling airline behavior in decentralized environments is also raised, and an example of such a model, which deals with the preservation of flight bank integrity in hub airports, is presented.

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

    Directory of Open Access Journals (Sweden)

    Garrett Pierman

    2015-12-01

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

  3. Environment as the Stage for Economic Actors

    John E Coulter; Shi Lei; Samantha Jenkins

    2007-01-01

    The relative importance of economics and environment in debate may soon be reversed due to the influence of three factors. Firstly, in the global economy it is hard to hide the unwanted products of economic processes. Secondly, huge advances in science will reduce the imperfect knowledge of markets, making some monitoring and analyzing tools show the design of sensible and equitable livelihood in communities, which is more important than the motivation of maximising profits for some individuals or fums. Thirdly, China, as the last major player on the planet to take on economic growth, comes from traditions fundamentally different from those economies that have experienced the Industrial Revolution previously. Its challenges with sustainability and environmental conservation predate Western economics by millennia,and it is implementing policies domestically and starting to work on the world stage that acknowledges that the surroundings are the host for any economic and socio-political system.

  4. The impact of fiscal decentralization on infant mortality rates: evidence from OECD countries.

    Jiménez-Rubio, Dolores

    2011-11-01

    This study re-examines the hypothesis that shifts towards more decentralization would be accompanied by improvements in population health on a panel of 20 OECD countries over a thirty year period (1970-2001). Decentralization is proxied using a conventional indicator of revenue decentralization and a new measure of fiscal decentralization that reflects better than previous measures the existence of autonomy in the decision-making authority of lower tiers of government, a crucial issue in the decentralization process. The results show a considerable and positive effect of fiscal decentralization on infant mortality only if a substantial degree of autonomy in the sources of revenue is devolved to local governments. The proportion of health care expenditure on GDP and, in particular, education, were found to have a larger contribution to the reduction of infant mortality in the sample of OECD countries analysed over the period of study.

  5. ON DECENTRALIZED STABILIZATION OF LINEAR LARGE SCALE SYSTEMS WITH SYMMETRIC CIRCULANT STRUCTURE

    Institute of Scientific and Technical Information of China (English)

    金朝永; 张湘伟

    2004-01-01

    The decentralized stabilization of continuous and discrete linear large scale systems with symmetric circulant structure was studied. A few sufficient conditions on decentralized stabilization of such systems were proposed. For the continuous systems, by introducing a concept called the magnitude of interconnected structure, a very important property that the decentralized stabilization of such systems is fully determined by the structure of each isolated subsystem that is obtained when the magnitude of interconnected structure of the overall system is given. So the decentralized stabilization of such systems can be got by only appropriately designing or modifying the structure of each isolated subsystem,no matter how complicated the interconnected structure of the overall system is. A algorithm for obtaining decentralized state feedback to stabilize the overall system is given. The discrete systems were also discussed. The results show that there is a great dfference on decentralized stabilization between continuous case and discrete case.

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...... in situations of discontinuity. Therefore an analysis and comparison of relevant concepts that capture the key generative features of actor bonds in both socially constructed networks and socially constructed markets is undertaken. These concepts include the "milieu" of project marketing (Cova et al., 1996......) and the institutional concept of the "field". Finally this paper introduces the concept of "social capital" (Bourdieu, 1983) and discusses whether it can be used to conceptualize the dynamic features of actor bonds in situations of discontinuity....

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

    Directory of Open Access Journals (Sweden)

    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.

    Keystone species have a disproportionate influence on the structure and function of ecosystems. Here we analyze whether a keystone-like pattern can be observed in the relationship between transnational corporations and marine ecosystems globally. We show how thirteen corporations control 11-16% of the global marine catch (9-13 million tons) and 19-40% of the largest and most valuable stocks, including species that play important roles in their respective ecosystem. They dominate all segments of seafood production, operate through an extensive global network of subsidiaries and are profoundly involved in fisheries and aquaculture decision-making. Based on our findings, we define these companies as keystone actors of the Anthropocene. The phenomenon of keystone actors represents an increasingly important feature of the human-dominated world. Sustainable leadership by keystone actors could result in cascading effects throughout the entire seafood industry and enable a critical transition towards improved management of marine living resources and ecosystems.

  14. Universities as Potential Actors for Sustainable Development

    2014-05-01

    Full Text Available Universities can contribute to the solutions of major challenges of the 21st century such as increasing environmental and socio-economic crises, inequalities of income and wealth and political instabilities by integrating the concept of sustainable development (SD in research, organization, and by educating future decision makers. For instance, by integrating sustainability into the organization, universities can lead by example. Furthermore, through the curriculum, future decision makers can learn the competences needed to solve ecological, social, and economic problems in societies. However, despite their possible importance, universities in Germany fall behind internationally in implementing sustainable strategies. Therefore this paper presents/introduces an approach to how universities can implement the holistic concept of SD that considers all three dimensions (economic, ecological, and social relating to their main functions of research and education in addition to their organization. Additionally this paper analyzes the current state of implementing sustainability strategies at universities, and how the success of these implementation efforts can be evaluated and be fostered further. We find that assessment systems enable universities to systematically use their potential for action for SD by initiating, evaluating, and accelerating the sustainability process. This also applies in the case of German universities, where the implementation of SD is still in the early stages.

O Estado poderá usar o discurso da descentralização para defender mais autonomia e responsabilidade, tal como as forças de mercado poderão empregá-lo para orientar os seus objetivos em relação às escolas. Neste artigo pretendemos identificar uma série de diferentes significados para a palavra descentralização, argumentando que o currículo é um processo intencional e prático em que os principais atores são os professores e os alunos. O ponto central é como caminharmos fora das linhas. A provável resposta introduz a centralidade da escola sem minimizar a importância das questões curriculares.The idea of decentralization became central to educational discourse during the period of reform of the late 1980s and the 1990s. The State can use the discourse of decentralization to argue in favor of greater autonomy and responsibility, just as market forces can use it to attain their objectives in regard to schools. In this article our purpose is to identify a number of different meanings of the term decentralization, arguing that decisions regarding curricula are intentional and practical processes in which students and teachers are the main actors. The key question is how to move ahead off the beaten path. The probable answer will be based on the centrality of the school without minimizing the importance of curriculum-related issues.

    Mok, Joshua Ka-Ho

    2001-03-01

    In China there has been a strong trend to diversification and decentralization of education in the post-Mao period. This paper examines how the policy of decentralization has affected the governance of universities in Guangdong. More specifically, the paper focuses on reform of the financing and management structure, the merging of universities, and joint development programmes to enhance competitiveness. Despite these changes, the state's role as a regulator and overall service coordinator has been strengthened rather than weakened under the policy of decentralization. This paper not only examines the recent developments in Guangdong's higher education but also analyses such developments in light of the global trend towards decentralization in educational governance.

    also build endogenous roads, facilitating the entry of other actors. Future movements of actors will be influenced by major infrastructure plans, such as those for hydroelectric dams. Policies for reducing deforestation must include removing motives for deforestation by stopping the practice of regularizing land claims and by cutting subsidies. The rule of law must be established throughout the region by completing the cadaster, or register, of land titles and by reinforcing command and control. Movement to the frontier needs to be discouraged by exercising restraint in approving infrastructure such as highways, and by creating and protecting conservation units. Economic alternatives to deforestation should be fostered by generating employment in source areas and in alternative migration destinations, by supporting sustainable uses of forest, by supporting alternative supply of domestic markets for products such as timber, and by rewarding the environmental services of standing forest.

  1. Risk: For Whom? Representations of Mining Activity by Different Social Actors in the Molango Manganese District of Hidalgo, Mexico.

    Catalán-Vázquez, Minerva; Riojas-Rodríguez, Horacio; Pelcastre-Villafuerte, Blanca Estela

    2014-01-01

    Previous studies have shown high levels of manganese exposure and neurocognitive damage in the population living in the mining zone in Molango, Mexico. One of the objectives of the Intersectoral Group on Environmental Management for the mining district has been to provide public participation in the risk management plan. To achieve this, it is important to know how the different social actors represent the mining activity. The objectives of this study were to characterize the social representations of the mining activity by different social actors. A qualitative design was used based on in-depth interviews of residents, public officials, and a mining company representative. The analysis was conducted according to themes for each group of actors. Essentially, distinct social representations of the different mining activities were identified. Residents viewed mining activities as synonymous with contamination and, therefore, as having affected all areas of their environment, health, and daily life. These activities were seen as a collective risk. The public officials and the mining company held that there was no evidence of harm and saw mining activities as a generator of regional development. Harm to health and the environment were seen as a stance taken by the communities in order to obtain economic benefits from the company. These images of the "other" are shaped by social, political, and cultural factors. They make it difficult for the actors to reach cooperative agreements and thereby affect progress on the risk management plan. Decisionmakers need to take these differences into account when promoting social participation.

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

    Full Text Available Typically, the decentralization process is extremely complicated and involves many challenges, if we were to take into account local conflicts, the interests of the central government and the complexity of simultaneous decentralization in administrative, political and economic plan. The financial crisis has added another dimension to the complexity of this phenomenon, misbalancing the economy and creating a fiscal pressure both at central and local level. In this context it rises the problem whether the management of the financial crisis can be better realised within a decentralized system or whether it may lay pressure on the return to the centralized government form.

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

    Mueller, Joseph .; Thomas, Stephanie J.

    2005-01-01

    This paper presents the prototype of a system that addresses these objectives-a decentralized guidance and control system that is distributed across spacecraft using a multiple-team framework. The objective is to divide large clusters into teams of manageable size, so that the communication and computational demands driven by N decentralized units are related to the number of satellites in a team rather than the entire cluster. The system is designed to provide a high-level of autonomy, to support clusters with large numbers of satellites, to enable the number of spacecraft in the cluster to change post-launch, and to provide for on-orbit software modification. The distributed guidance and control system will be implemented in an object-oriented style using MANTA (Messaging Architecture for Networking and Threaded Applications). In this architecture, tasks may be remotely added, removed or replaced post-launch to increase mission flexibility and robustness. This built-in adaptability will allow software modifications to be made on-orbit in a robust manner. The prototype system, which is implemented in MATLAB, emulates the object-oriented and message-passing features of the MANTA software. In this paper, the multiple-team organization of the cluster is described, and the modular software architecture is presented. The relative dynamics in eccentric reference orbits is reviewed, and families of periodic, relative trajectories are identified, expressed as sets of static geometric parameters. The guidance law design is presented, and an example reconfiguration scenario is used to illustrate the distributed process of assigning geometric goals to the cluster. Next, a decentralized maneuver planning approach is presented that utilizes linear-programming methods to enact reconfiguration and coarse formation keeping maneuvers. Finally, a method for performing online collision avoidance is discussed, and an example is provided to gauge its performance.

    1998-07-01

    Full text of publication follows: the concept of centralization/decentralization is - considering its widespread use - surprisingly ill-defined. Within the SERF-program (Socio Economic Research on Fusion) an attempt is made to clarify the complex issue of centralization/decentralization and to analyze its expected interaction with electricity production system in the case of nuclear fusion. Fusion research at the time is a multinational, highly centralized undertaking. As a result of this, and due to the expected large energy production units, it is generally expected that fusion will be embedded in a highly centralized, international energy supply system. The degree of centralization of an energy supply system, however, is believed to have for reaching consequences on the stability of the system, and beyond that, on decision making processes in energy policy, as well as democratic structures on the national or even international level. Internationalization might require control instruments that do not exist so far. Amongst other reservations, it is the possibly unwanted consequences of such a highly centralized, international energy supply system that limit acceptance of the fusion technology in the public. Therefore, centralization and decentralization trends of energy supply systems over the years are being looked at, to study their influence on the political and social systems (and vice-versa). In a first step, an attempt is made to classify centralization. Careful analyses and evaluation of available literature revealed a broad spectrum of different forms and degrees of centralization. Various parameters describing energy production and distribution are used. A differentiation of centralization on a technical and on an organizational level seems necessary, although they are not fully independent of each other. Beyond this, the choice of parameters must depend on the questions to be addressed. A new approach defining different levels and degrees of

    Full Text Available OBJECTIVE: To identify the effects of decentralization on health financing and governance policies in Mexico from the perspective of users and providers. METHODS: A cross-sectional study was carried out in four states that were selected according to geopolitical and administrative criteria. Four indicators were assessed: changes and effects on governance, financing sources and funds, the final destination of resources, and fund allocation mechanisms. Data collection was performed using in-depth interviews with health system key personnel and community leaders, consensus techniques and document analyses. The interviews were transcribed and analyzed by thematic segmentation. RESULTS: The results show different effectiveness levels for the four states regarding changes in financing policies and community participation. Effects on health financing after decentralization were identified in each state, including: greater participation of municipal and state governments in health expenditure, increased financial participation of households, greater community participation in low-income states, duality and confusion in the new mechanisms for coordination among the three government levels, absence of an accountability system, lack of human resources and technical skills to implement, monitor and evaluate changes in financing. CONCLUSIONS: In general, positive and negative effects of decentralization on health financing and governance were identified. The effects mentioned by health service providers and users were related to a diversification of financing sources, a greater margin for decisions around the use and final destination of financial resources and normative development for the use of resources. At the community level, direct financial contributions were mentioned, as well as in-kind contributions, particularly in the form of community work.

    This work presents a design of decentralized PI type Linear Quadratic (LQ) controller based on genetic algorithm (GA). The proposed design technique allows considerable flexibility in defining the control objectives and it does not consider any knowledge of the system matrices and moreover it avoids the solution of algebraic Riccati equation. To illustrate the results of this work, a load-frequency control problem is considered. Simulation results reveal that the proposed scheme based on GA is an alternative and attractive approach to solve load-frequency control problem from both performance and design point of views.

    One approach to the decentralized control of large flexible space structures involves the design of controllers for the substructures of large systems and their subsequent application to the entire coupled system. This approach is presently developed for the case of active vibration damping on an experimental large struss structure. The isolated boundary loading method is used to define component models by FEM; component controllers are designed using an interlocking control concept which minimizes the motion of the boundary nodes, thereby reducing the exchange of mechanical disturbances among components.

    Full Text Available Nonfood lignocellulosic biomass is an ideal substrate for biohydrogen production. By avoiding pretreatment steps (acid, alkali, or enzymatic, there is potential to make the process economical. Utilization of regional untreated lignocellulosic biomass by cellulolytic and fermentative thermophiles in a consolidated mode using a single reactor is one of the ways to achieve economical and sustainable biohydrogen production. Employing these potential microorganisms along with decentralized biohydrogen energy production will lead us towards regional and national independence having a positive influence on the bioenergy sector.

    A great deal of stabilization criteria has been obtained from study of stabilizing interconnected systems. The results obtained are usually based on continuous systems by state feedback. In this paper, decentralized impulsive control is presented to stabilize a class of uncertain interconnected systems based on Lyapunov theory. The system under consideration involves parameter uncertainties and unknown nonlinear interactions among subsystems. Some new criteria of stabilization under impulsive control are established. Two numerical examples are offered to prove the effectiveness and practicality of the proposed method.

    A decentralized generalized predictive control (GPC) algorithm is developed for strongly coupled multi-input multi-output systems with parallel computation. The algorithm is applied to adaptive control of structural vibration. The key steps in this algorithm are to group the actuators and the sensors and then to pair these groups into subsystems. It is important that the on-line identification and the control law design can be a parallel process for all these subsystems. It avoids the high computation cost in ordinary predictive control,and is of great advantage especially for large-scale systems.

    The robust decentralized adaptive output-feedback stabilization for a class of interconnected systems with static and dynamic interconnections by using the MT-filters and backstepping design method is studied. By introducing a new filtered tramformation, the adaptive laws were derived for measurement. Under the assumption of the nonlinear growth conditions imposed on the nonlinear interconnections and by constructing the error system and using a new proof method, the global stability of the closed-loop system was effectively analyzed, and the exponential convergence of all the signals except for parameter estimates were guaranteed.

    Dhaka's community-based decentralized composting (DCDC) is a successful demonstration of solid waste management by adopting low-cost technology, local resources community participation and partnerships among the various actors involved. This paper attempts to understand the model, necessary conditions, strategies and their priorities to replicate DCDC in the other developing cities of Asia. Thirteen strategies required for its replication are identified and assessed based on various criteria, namely transferability, longevity, economic viability, adaptation and also overall replication. Priority setting by multi-criteria analysis by applying analytic hierarchy process revealed that immediate transferability without long-term and economic viability consideration is not advisable as this would result in unsustainable replication of DCDC. Based on the analysis, measures to ensure the product quality control; partnership among stakeholders (public-private-community); strategies to achieve better involvement of the private sector in solid waste management (entrepreneurship in approach); simple and low-cost technology; and strategies to provide an effective interface among the complementing sectors are identified as important strategies for its replication.

    Fiscal Decentralization (FD) in many cases is encouraged as a strong means of improving the efficiency and equity in the provision of public goods, such as healthcare services. This issue has urged the researchers to experimentally examine the relationship between fiscal decentralization indicators and health outcomes. In this study we examine the effect of Fiscal Decentralization in Medical Universities (FDMU) and Fiscal Decentralization in Provincial Revenues (FDPR) on Under-Five Mortality Rate (U5M) in provinces of Iran over the period between 2007 and 2010. We employed panel data methods in this article. The results of the Pesaran CD test demonstrated that most of the variables used in the analysis were cross-sectionally dependent. The Hausman test results suggested that fixed-effects were more appropriate to estimate our model. We estimated the fixed-effect model by using Driscoll-Kraay standard errors as a remedy for cross-sectional dependency. According to the findings of this research, fiscal decentralization in the health sector had a negative impact on U5M. On the other hand, fiscal decentralization in provincial revenues had a positive impact on U5M. In addition, U5M had a negative association with the density of physicians, hospital beds, and provincial GDP per capita, but a positive relationship with Gini coefficient and unemployment. The findings of our study indicated that fiscal decentralization should be emphasized in the health sector. The results suggest the need for caution in the implementation of fiscal decentralization in provincial revenues.

    The decentralization of healthcare services is becoming increasingly important in strategies of public sector management. This concept is analyzed from various points of view, including legal, economic, political, and sociological. Several typologies have been proposed in the literature to analyze this decentralization process, which can take different forms ranging from simple deconcentration to more elaborate devolution. In some instances, decentralization can be analyzed by the degree of autonomy given to local authorities. This article applies these typologies to analyze the healthcare system decentralization process in Cote d'Ivoire. Special attention is paid to the new forms of community healthcare organizations. These decentralized structures enjoy a kind of autonomy, with characteristics closer to those of devolution. The model might serve as an example for population involvement in defining and managing healthcare problems in Cote d'Ivoire. We end with proposals for the improvement of the process.

  1. Balancing influence between actors in healthcare decision making

    Directory of Open Access Journals (Sweden)

    Babad Yair M

    2011-04-01

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

  2. ABS-NET: Fully Decentralized Runtime Adaptation for Distributed Objects

    Directory of Open Access Journals (Sweden)

    Karl Palmskog

    2013-10-01

    Full Text Available We present a formalized, fully decentralized runtime semantics for a core subset of ABS, a language and framework for modelling distributed object-oriented systems. The semantics incorporates an abstract graph representation of a network infrastructure, with network endpoints represented as graph nodes, and links as arcs with buffers, corresponding to OSI layer 2 interconnects. The key problem we wish to address is how to allocate computational tasks to nodes so that certain performance objectives are met. To this end, we use the semantics as a foundation for performing network-adaptive task execution via object migration between nodes. Adaptability is analyzed in terms of three Quality of Service objectives: node load, arc load and message latency. We have implemented the key parts of our semantics in a simulator and evaluated how well objectives are achieved for some application-relevant choices of network topology, migration procedure and ABS program. The evaluation suggests that it is feasible in a decentralized setting to continually meet both the objective of a node-balanced task allocation and make headway towards minimizing communication, and thus arc load and message latency.

    Directory of Open Access Journals (Sweden)

    Kyung-Geun Lee

    2013-06-01

    Full Text Available Femtocells represent a novel configuration for existing cellular communication, contributing towards the improvement of coverage and throughput. The dense deployment of these femtocells causes significant femto-macro and femto-femto interference, consequently deteriorating the throughput of femtocells. In this study, we compare two heuristic approaches, i.e., particle swarm optimization (PSO and genetic algorithm (GA, for joint power assignment and resource allocation, within the context of the femtocell environment. The supposition made in this joint optimization is that the discrete power levels are available for the assignment. Furthermore, we have employed two variants of each PSO and GA: inertia weight and constriction factor model for PSO, and twopoint and uniform crossover for GA. The two proposed algorithms are in a decentralized manner, with no involvement of any centralized entity. The comparison is carried out between the two proposed algorithms for the aforementioned joint optimization problem. The contrast includes the performance metrics: including average objective function, min–max throughput of the femtocells, average throughput of the femto users, outage rate and time complexity. The results demonstrate that the decentralized PSO constriction factor outperforms the others in terms of the aforementioned performance metrics.

    2012-06-01

    This paper presents an analysis of large scale decentralized SLAM under a variety of experimental conditions to illustrate design trade-offs relevant to multi-robot mapping in challenging environments. As a part of work through the MAST CTA, the focus of these robot teams is on the use of small-scale robots with limited sensing, communication and computational resources. To evaluate mapping algorithms with large numbers (50+) of robots, we developed a simulation incorporating sensing of unlabeled landmarks, line-of-sight blocking obstacles, and communication modeling. Scenarios are randomly generated with variable models for sensing, communication, and robot behavior. The underlying Decentralized Data Fusion (DDF) algorithm in these experiments enables robots to construct a map of their surroundings by fusing local sensor measurements with condensed map information from neighboring robots. Each robot maintains a cache of previously collected condensed maps from neighboring robots, and actively distributes these maps throughout the network to ensure resilience to communication and node failures. We bound the size of the robot neighborhoods to control the growth of the size of neighborhood maps. We present the results of experiments conducted in these simulated scenarios under varying measurement models and conditions while measuring mapping performance. We discuss the trade-offs between mapping performance and scenario design, including robot teams separating and joining, multi-robot data association, exploration bounding, and neighborhood sizes.

    Full Text Available Since the late 1970’s, the Chinese government has been gradually changing its traditional policy for providing higher education and has begun to emphasize the comprehensiveness of the universities. Interdisciplinary cooperation and the synergization of resources are being promoted, and institutional autonomy is gradually increasing. Schools and faculties have been restored in universities, and new research institutions, research schools, research centers and the like have been established. From a unitary three-level model— university/department/ teaching and research group—before the reform, the organizational structures of the universities have developed a new organizational structure that is more flexible and more open. This more adaptable structure is intended to meet the developmental demands of modern universities with close links being created between their work and regional economic and social development. China has moved from a very centralized educational system in which the main decisions were taken by the central government to a decentralized educational system. This reform is also taking place within the institutions of higher education, and their internal organizational structure has also become more decentralized.

  6. Energy conservation and energy decentralization: issues and prospects

    Views are presented of the seemingly paradoxical nature and irrationality of the energy system and the decisions that determine its evolution. An economic approach to energy decisions, while widely espoused and generally believed to be the underpinning of our system, appears not to be functioning in very-important areas. The result is enormous waste of economic and intangible resources to produce energy that could be effectively replaced by energy conservation at low costs. This inefficiency in the economic system is, in the author's judgment, far greater than is recognized either by the public or by experts. They feel it has led to an over-investment in centralized energy systems and has discouraged the use of decentralized systems that could contribute significantly in the near term to a lessening of our energy problems. There are some signs that the situation is changing, albeit rather slowly. High prices and the widespread recognition of the seriousness of our energy problems have contributed to an increasing involvement of individuals in energy decisions profoundly affecting their future. To achieve an evolution of the energy system in which decentralized technologies (and, in the near term, particularly technologies that improve the efficiency of energy use) play an important role, the government must act forcefully. This action needs to recognize and be responsive to the powerful discriminatory effect of the economic system, as it is presently constituted, against investments in energy conservation.

    Full Text Available In the paper, the new additional indicators of energy security with the purpose to include decentralized heating sector is developed in the work. The structure of the housing stock of the country is analyzed, which includes different types of central heating boilers and CHP, individual gas or electric heating and stove heating.The analysis of the existing thermal supply (per unit area and per capita living for each sector is carried out. It is found that heat consumed in the residential sector with central heating from CHP and boilers is significantly higher of heat consumed in other sectors. The missing amount of heat energy, which can be produced in two ways, is calculated. Part of the deficit heat can be produced at existing sources that are not loaded enough to the nominal parameters at the moment. The second part can be obtained from small new sources (for inhabited localities that do not have a centralized heat supply infrastructure. New indicators complement the system of indicators to be used to analyze and monitoring the level of Moldova's energy security. They allowed including decentralized heat supply sector, which is not reflected in the official statistics. At the same, the calculation methodology has been improved and the overall integral indicator of the energy security level, which was even more crisis than previously thought.

  8. Decentralized Optimal Dispatch of Photovoltaic Inverters in Residential Distribution Systems

    Summary form only given. Decentralized methods for computing optimal real and reactive power setpoints for residential photovoltaic (PV) inverters are developed in this paper. It is known that conventional PV inverter controllers, which are designed to extract maximum power at unity power factor, cannot address secondary performance objectives such as voltage regulation and network loss minimization. Optimal power flow techniques can be utilized to select which inverters will provide ancillary services, and to compute their optimal real and reactive power setpoints according to well-defined performance criteria and economic objectives. Leveraging advances in sparsity-promoting regularization techniques and semidefinite relaxation, this paper shows how such problems can be solved with reduced computational burden and optimality guarantees. To enable large-scale implementation, a novel algorithmic framework is introduced - based on the so-called alternating direction method of multipliers - by which optimal power flow-type problems in this setting can be systematically decomposed into sub-problems that can be solved in a decentralized fashion by the utility and customer-owned PV systems with limited exchanges of information. Since the computational burden is shared among multiple devices and the requirement of all-to-all communication can be circumvented, the proposed optimization approach scales favorably to large distribution networks.

  9. Convergent Double Auction Mechanism for a Prosumers’ Decentralized Smart Grid

    2015-10-01

    Full Text Available In this paper, we propose a novel automated double auction mechanism called convergent linear function submission-based double-auction (CLFS-DA for a prosumers’ decentralized smart grid. The target decentralized smart grid is a regional electricity network that consists of many prosumers that have a battery and a renewable energy-based generator, such as photovoltaic cells. In the proposed double-auction mechanism, each intelligent software agent representing each prosumer submits linear demand and supply functions to an automated regional electricity market where they are registered. It is proven that the CLFS-DA mechanism is guaranteed to obtain one of the global optimal price profiles in addition to it achieving an exact balance between demand and supply, even through the learning period. The proof of convergence is provided on the basis of the theory of LFS-DA, which gives a clear bridge between a function submission-based double auction and a dual decomposition (DD-based real-time pricing procedure. The performance of the proposed mechanism is demonstrated numerically through a simulation experiment.

    2009-05-01

    Full Text Available The public economic literature of the past century is characterized by a traditional paradigm that ascribes little attention to the spatial dimension. However, contemporary globalization requires that researchers and economists expand their perspectives to consider space conceptualization. What is required in the 21st century is a richer and more realistic framework that broadens existing concepts of socio-economic analysis while overcoming narrow national borders. Although national governments will remain prominent performers in the global market, regional and local governments cannot be ignored because citizens worldwide are exerting greater self-determination in influencing governmental decisions. This paper is focused on the opportunity to analyze the governance of decentralization by the new optimizing procedures provided by complex system theory. The first section of the paper explores the positive and normative issues related to centralization and decentralization in a globalized framework as well as the increased interdependence in power sharing among different jurisdictional level. In the second section, Kauffman’s (1993 contributions are examined as a means of determining if the fitness landscape allows combining the institutional evolution. Finally, this paper concludes highlighting that complex system theory is one of the possible tools useful to redesign the map of institutional sharing power in an era of globalization, considering that it allows catching Pareto improving in the level of welfare.

  11. Outdoor flocking of quadcopter drones with decentralized model predictive control.

    Yuan, Quan; Zhan, Jingyuan; Li, Xiang

    2017-07-11

    In this paper, we present a multi-drone system featured with a decentralized model predictive control (DMPC) flocking algorithm. The drones gather localized information from neighbors and update their velocities using the DMPC flocking algorithm. In the multi-drone system, data packages are transmitted through XBee(®) wireless modules in broadcast mode, yielding such an anonymous and decentralized system where all the calculations and controls are completed on an onboard minicomputer of each drone. Each drone is a double-layered agent system with the coordination layer running multi-drone flocking algorithms and the flight control layer navigating the drone, and the final formation of the flock relies on both the communication range and the desired inter-drone distance. We give both numerical simulations and field tests with a flock of five drones, showing that the DMPC flocking algorithm performs well on the presented multi-drone system in both the convergence rate and the ability of tracking a desired path.

    We consider the problem of decentralized hypothesis testing in a network of energy harvesting sensors, where sensors make noisy observations of a phenomenon and send quantized information about the phenomenon towards a fusion center. The fusion center makes a decision about the present hypothesis using the aggregate received data during a time interval. We explicitly consider a scenario under which the messages are sent through parallel access channels towards the fusion center. To avoid limited lifetime issues, we assume each sensor is capable of harvesting all the energy it needs for the communication from the environment. Each sensor has an energy buffer (battery) to save its harvested energy for use in other time intervals. Our key contribution is to formulate the problem of decentralized detection in a sensor network with energy harvesting devices. Our analysis is based on a queuing-theoretic model for the battery and we propose a sensor decision design method by considering long term energy management at the sensors. We show how the performance of the system changes for different battery capacities. We then numerically show how our findings can be used in the design of sensor networks with energy harvesting sensors.

  13. Decentralized enforcement, sequential bargaining, and the clean development mechanism

    Energy Technology Data Exchange (ETDEWEB)

    Hovi, Jon

    2001-07-01

    While there is a vast literature both on international bargaining and on how international agreements can be enforced, very little work has been done on how bargaining and enforcement interact. An important exception is Fearon (1998), who models international cooperation as a two-stage process in which the bargaining process is constrained by a need for decentralized enforcement (meaning that the agreement must be enforced by the parties themselves rather than a third party, such as a court). Using the Clean Development Mechanism as an example, the present paper proposes a different model of this kind of interaction. The model follows Fearon's in so far as we both use the infinitely repeated Prisoners' Dilemma to capture the enforcement phase of the game. However, while Fearon depicts the bargaining stage as a War of Attrition, the present model sees that stage as a sequential bargaining game of the Staahl-Rubinstein type. The implications of the present model are compared both to those of the Staahl-Rubinstein model and to those of the Fearon model. A surprising conclusion is that a need for decentralized enforcement tends to make the bargaining outcome more symmetrical than otherwise. Thus, the impact of bargaining power is actually smaller when the resulting agreement must be enforced by the parties themselves than it is if enforcement is taken care of by a third party. (author)

    2015-01-01

    Selection of treatment technologies without considering the environmental, economic and social factors associated with each geographical context risks the occurrence of negative impacts that were not properly foreseen, working against the sustainable performance of the technology. The principal aim of this study was to evaluate 12 technologies for decentralized treatment of domestic wastewater applicable to peri-urban communities using sustainability approaches and, at the same time, continuing a discussion about how to address a more integrated assessment of overall sustainability. For this, a set of 13 indicators that embody the environmental, economic and social approach for the overall sustainability assessment were used by means of a target plot diagram as a tool for integrating indicators that represent a holistic analysis of the technologies. The obtained results put forward different degrees of sustainability, which led to the selection of: septic tank+land infiltration; up-flow anaerobic reactor+high rate trickling filter and septic tank+anaerobic filter as the most sustainable and attractive technologies to be applied in peri-urban communities, according to the employed indicators.

    2014-04-01

    Full Text Available The actor network procedures of Pavlovic and Meadows are a recent graphical formalism developed for describing security ceremonies and for reasoning about their security properties. The present work studies the relations of the actor network procedures (ANP to the recent psi-calculi framework. Psi-calculi is a parametric formalism where calculi like spi- or applied-pi are found as instances. Psi-calculi are operational and largely non-graphical, but have strong foundation based on the theory of nominal sets and process algebras. One purpose of the present work is to give a semantics to ANP through psi-calculi. Another aim was to give a graphical language for a psi-calculus instance for security ceremonies. At the same time, this work provides more insight into the details of the ANPs formalization and the graphical representation.

    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.

    Collins, Harry; Evans, Robert

    2014-10-01

    We question the logic of Coopmans and Button's critique of our analysis of expertise on three grounds. First, their critique depends on a clear distinction between actor and analysts that we show cannot be maintained. Second, we question their reticence to allow the use of taxonomies in the analysis of expertise, suggesting that it is contradicted by their own descriptions of expert work, and we accuse them of making a mistake in the way they relate commonsense to specialist skills. Finally, we express our puzzlement at the antiseptic-like precautions that some ethnomethodologists apply to analysts' categories, especially given that--as we show--analysts' categories sometimes provide a superior resource for understanding and can change the actors' world as well as describing it.

    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)

    In the spring of 2006, a rather unusual advertisement by the Centre of Teaching and Academic Growth at UBC (http://www.tag.ubc.ca) came to my attention. Faculty members were invited to take part in a workshop entitled "All the World's a Stage: Teachers as Actors," offered by a zoology instructor and an amateur actor, Greg Bole: Teaching can be seen as creating an interpersonal relationship and hence uses many of the same skills as acting. The investigation and use of acting skills in teacher preparation can allow a greater facility with diverse methods, increase skill at adapting to change in the classroom or lecture hall, and an increased ability to quickly form positive relationships with students.

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

    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.

    Full Text Available In contemporary Ghana, the traditional system and professional social work operate as two parallel systems within the field of social work. The aim of this study was to investigate if and how the teaching of contemporary professional social work in Ghana takes into account traditional actors and practices. The traditional system includes extended family members and traditional authorities such as chiefs or family heads. It formed the social institution that protected and cared for the vulnerable before (Western social work was introduced as a formal profession in Ghana. A 10-week ethnographic field study was conducted at the Department of Social Work at the University of Ghana. The study employed a qualitative, social constructionist approach, interpreting the results within a theoretical framework of social world theory. The empirical material consisted of interviews with students and teachers, participant observation at lectures, and various documents. The main findings of the study were that professional social workers and traditional actors can be seen as members of two subworlds – the subworld of professional social workers and the subworld of traditional actors. Students and teachers discuss interventions from the perspective of social workers and traditional actors. Their ability to take different perspectives seems to be crucial for localisation – the process by which social work is made relevant to local culture and traditions. The interviewees’ accounts reveal how localisation is not only about culture, but also about social structures and practical considerations. The poor state of the social work profession in Ghana affects interventions in a profound way.

  10. Values of decentralized systems that avoid investments in idle capacity within the wastewater sector: a theoretical justification.

    Science.gov (United States)

    Wang, Sheng

    2014-04-01

    In this work, the values of decentralized (onsite) systems that avoid investments in idle capacity within wastewater plans are quantitatively justified using the specific net present value (SNPV) approach. SNPV is a currently proposed criterion in environmental engineering economics that is defined as the net present value of the cost per unit of service or per population equivalent (PE). The SNPV approach was reintroduced with bugs fixed and then applied to the economic analysis of the capital and operating costs of one-stage completed central plants, stage-expanded central plants, and decentralized treatment facilities. The results show that under a demand growth scenario, the central plant will inevitably reach idle capacity, which can be reduced by a staged expansion. However, the staged expansion plan will lose the economies of scale and, hence, is only viable under projections of a low or moderate price inflation rate or high demand growth rate. Onsite treatment systems can theoretically achieve 100% utilization. Assuming that the capital costs per PE of the onsite and central systems are equal, the former is economically favorable in most cases of price inflation as a result of its cost saving on idle capacity. Onsite treatment systems can be viable even though their capital expenditures per PE are higher than that of a comparable centralized option as to a capital investment. This finding suggests wide opening of onsite technology choices. Use of the SNPV showed that average operating expenses of centralized plants decrease as demand growth rates increase as a benefit of economies of scale, whereas those of onsite treatment systems depend only on price inflation. Semi-decentralized systems feature both the financial advantage of the onsite system (capital investment) and the superiority of centralized systems (operation and maintenance); thus, it is worth consideration. The results of this study illustrate not only the value of decentralized systems but

  11. 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.

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

    Science.gov (United States)

    McAdams, Dan P

    2013-05-01

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

    Full Text Available The objective of this work is to establish an information system which would facilitate decision making for the exploitation of a model consisting of the main stakeholders of the university (teachers, students and administrators. This system is based on the relationship between actors (players on the one hand and their activities and their aggregations in a graduate level on the other. It aims to make available to managers of the university a set of dashboards that can improve the quality of education. We will start by modeling the actors upstream and we will study the processes on their own organizations, their activities and their aggregations. This approach is based on the analysis made by the actors to switch to an information technology approach in the process of searching for knowledge. The first applications of this work focus on data related to the department of English Studies at the Faculty of Arts and Humanities at Ibn Zohr University in Agadir, Morocco. The results are encouraging and can be generalized to all courses offered by academic institutions.

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

  18. Decentralized formation flying control in a multiple-team hierarchy.

    In recent years, formation flying has been recognized as an enabling technology for a variety of mission concepts in both the scientific and defense arenas. Examples of developing missions at NASA include magnetospheric multiscale (MMS), solar imaging radio array (SIRA), and terrestrial planet finder (TPF). For each of these missions, a multiple satellite approach is required in order to accomplish the large-scale geometries imposed by the science objectives. In addition, the paradigm shift of using a multiple satellite cluster rather than a large, monolithic spacecraft has also been motivated by the expected benefits of increased robustness, greater flexibility, and reduced cost. However, the operational costs of monitoring and commanding a fleet of close-orbiting satellites is likely to be unreasonable unless the onboard software is sufficiently autonomous, robust, and scalable to large clusters. This paper presents the prototype of a system that addresses these objectives-a decentralized guidance and control system that is distributed across spacecraft using a multiple team framework. The objective is to divide large clusters into teams of "manageable" size, so that the communication and computation demands driven by N decentralized units are related to the number of satellites in a team rather than the entire cluster. The system is designed to provide a high level of autonomy, to support clusters with large numbers of satellites, to enable the number of spacecraft in the cluster to change post-launch, and to provide for on-orbit software modification. The distributed guidance and control system will be implemented in an object-oriented style using a messaging architecture for networking and threaded applications (MANTA). In this architecture, tasks may be remotely added, removed, or replaced post launch to increase mission flexibility and robustness. This built-in adaptability will allow software modifications to be made on-orbit in a robust manner. The

    It must be emphasized that none of the steps described in this planning process emerged overnight. Rather, they were achieved through a process of evolution, sometimes through trial and error, and always with consultation and participation by many members of the hospital nursing staff. Participation by many in the process of planning for a workable staffing system has been essential to its success. Indeed, creative scheduling by the head nurse is possible because of the way in which the system has been organized. The fact that head nurses are responsible for staffing their own units makes it infinitely easier for them to see what they need to make their units operate effectively and efficiently. Creative scheduling includes the possibility of arranging nurses' hours outside the rigid three-shift schedule used by so many hospitals. Many El Camino nurses now report for work at different hours. In addition, the use of flexible work weeks has proven valuable. Some head nurses now allow for a ten-hour, four-day work week; in emergency staffing situations there have, on occasion, been twelve-hour days. Even as this system evolves, it faces change. Just as the requirements for staff cannot be rigid, so must problem solving be flexible and constantly under review. The fact that El Camino believes in constant monitoring of its system is essential to its success. A key philosophical foundation of decentralization is that it must be subject to change. This is no less true in staffing than in other parts of the decentralization structure. By agreeing that change is constant and necessary and that participation is required at all levels of the staffing planning process, we have constructed the outlines of a system that will work in the future as well as it does in the present. Our system centers around the head nurses. It involves their planning; thus it also involves the support of those members of the nursing staff who can provide essential information. But the decisions

  20. Regional Development and Decentralization – two Options to Overcome Lack of Funding

    Full Text Available Decentralization can be generally described as a process in which selected functions are assigned to sub-national units. The literature identifies a number of positive consequences of decentralization which all lead to a better satisfaction of citizens’ needs for public services. Although the decentralization process in Croatia started more than ten years ago, it has not yet been completed. While leading to a new allocation of authorities and responsibilities to local government units, the level of fiscal decentralization remained lower than in the EU countries.In this paper we analyze the fiscal capacity of local government units to provide an insight into the main problems of decentralization in Croatia. We show that most local government units have very low fiscal capacity, which is insufficient for financing basic public functions with their own resources. The paper presents the results of a survey relating to the decentralization process conducted among local councilors at the regional level in Croatia. We explore how local councilors at the regional level evaluate different goals of decentralization. With the lack of fiscal capacity in mind, we identify two possible solutions for an optimal provision of public functions. The first one is the level of political will for a joint provision of public functions by different local units, and the second one is a change in the territorial organization of the country. We measure the difference in the attitudes toward these questions across counties.

  1. The tradeoff between centralized and decentralized health services: evidence from rural areas in Mexico.

    This study investigates the effectiveness of centralized and decentralized health care providers in rural Mexico. It compares provider performance since both centralized and decentralized providers co-exist in rural areas of the country. The data are drawn from the 2003 household survey of Oportunidades, a comprehensive study of rural families from seven states in Mexico. The analyses compare out-of-pocket health care expenditures and utilization of preventive care among rural households with access to either centralized or decentralized health care providers. This study benefits from differences in timing of health care decentralization and from a quasi-random distribution of providers. Results show that overall centralized providers perform better. Households served by this organization report less regressive out-of-pocket health care expenditures (32% lower), and observe higher utilization of preventive services (3.6% more). Decentralized providers that were devolved to state governments in the early 1980s observe a slightly better performance than providers that were decentralized in the mid-1990s. These findings are robust to decentralization timing, heterogeneity in per capita government health expenditures, state and health infrastructure effects, and other confounders.

  2. Driving up Standards: Civil Service Management and Decentralization: Case Study of Uganda

    Directory of Open Access Journals (Sweden)

    2012-12-01

    Full Text Available There is a consensus that decentralization by devolution leads to improved service delivery, but debate on the appropriate type of personnel arrangements for delivering decentralized services is far from over. Put differently, the discourse on whether civil service management should be decentralized or devolved still rages on. Little wonder that countries which started off with decentralized civil service management models in the 1990s are currently centralizing some aspects of personnel management while others are having centralized and decentralized personnel arrangements operating side by side in sub-national governments. The paper argues that civil service management should be decentralized whenever a country chooses the path of decentralization by devolution. Using Uganda’s example, the paper highlights two major challenges of managing the civil service under separate personnel arrangements: civil service appointments devoid of merit, and the perennial failure to attract and retain qualified human resource. The paper presents proposals on how to ensure meritocracy in appointments and how to bolster attraction and retention of human capital in local governments.

    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’.

    Full Text Available Due to environmental burden and human health risks in developing countries, the treatment of decentralized domestic wastewater has been a matter of great concern in recent years. A novel pilot-scale three-stage anaerobic wool-felt filter reactor (AWFR was designed to treat real decentralized domestic wastewater at seasonal temperature variations of 8 to 35 °C for 364 days. The results showed that the average chemical oxygen demand (COD removal efficiencies of AWFR in summer and winter were 76 ± 7.2% and 52 ± 5.9% at one day and three days Hydraulic Retention Time (HRT, respectively. COD mass balance analysis demonstrated that even though COD removal was lower in winter, approximately 43.5% of influent COD was still converted to methane. High-throughput MiSeq sequencing analyses indicated that Methanosaeta, Methanobacterium, and Methanolinea were the predominant methanogens, whereas the genus Bacillus probably played important roles in fermentation processes throughout the whole operation period. The performance and microbial community composition study suggested the application potential of the AWFR system for the pretreatment of decentralized domestic wastewater.

    Efficient logistics systems move essential medicines down the supply chain to the service delivery point, and then to the end user. Experts on logistics systems tend to see the supply chain as requiring centralized control to be most effective. However, many health reforms have involved decentralization, which experts fear has disrupted the supply chain and made systems less effective. There is no consensus on an appropriate methodology for assessing the effectiveness of decentralization in general, and only a few studies have attempted to address decentralization of logistics systems. This paper sets out a framework and methodology of a pioneering exploratory study that examines the experiences of decentralization in two countries, Guatemala and Ghana, and presents suggestive results of how decentralization affected the performance of their logistics systems. The analytical approach assessed decentralization using the principal author's 'decision space' approach, which defines decentralization as the degree of choice that local officials have over different health system functions. In this case the approach focused on 15 different logistics functions and measured the relationship between the degree of choice and indicators of performance for each of the functions. The results of both studies indicate that less choice (i.e. more centralized) was associated with better performance for two key functions (inventory control and information systems), while more choice (i.e. more decentralized) over planning and budgeting was associated with better performance. With different systems of procurement in Ghana and Guatemala, we found that a system with some elements of procurement that are centralized (selection of firms and prices fixed by national tender) was positively related in Guatemala but negatively related in Ghana, where a system of 'cash and carry' cost recovery allowed more local choice. The authors conclude that logistics systems can be effectively

    1997-11-01

    With particular reference to the recently deregulated and market-based electricity industries in Norway, the UK and elsewhere the report analyses oligopoly entry and capacity investment decisions as a non-cooperative game in a decentralized electricity market. A two-stage game is considered, with multiple capacity types and uncertain demand, in which capacity decisions are made prior to spot-market, or price competition. Equilibrium outcomes for different pricing mechanisms or regulatory regimes are analysed. The following questions are dealt with in particular: Will industry capacity be sufficient to ensure adequate supply security? Does imperfect competition in the spot-market lead to an inefficient mix of base-load and peak-load technologies? How do different regulatory policies affect the market outcomes? 24 refs., 2 figs., 1 tab.

    2015-06-01

    Full Text Available In a recent French robotic contest, the objective was to develop a multi-robot system able to autonomously map and explore an unknown area while also detecting and localizing objects. As a participant in this challenge, we proposed a new decentralized Markov decision process (Dec-MDP resolution based on distributed value functions (DVF to compute multi-robot exploration strategies. The idea is to take advantage of sparse interactions by allowing each robot to calculate locally a strategy that maximizes the explored space while minimizing robots interactions. In this paper, we propose an adaptation of this method to improve also object recognition by integrating into the DVF the interest in covering explored areas with photos. The robots will then act to maximize the explored space and the photo coverage, ensuring better perception and object recognition.

    An accurate estimation of the sensor systematic error is significant for improving the performance of target tracking system. The existing methods usually append the bias states directly to the variable states to form augmented state vectors and utilize the conventional Kalman estimator to achieve state vectors estimate. So doing is expensive in computation, and much work is devoted to decoupling variable states and systematic error. But the decentralied estimation of systematic errors and reduction of the amount of computation as well as decentralied track fusion are far from being realized. This paper addresses distributed track fusion problem in multi-sensor tracking system in the presence of sensor bias. By this method, variable states and systematic error is decoupled. Decentralized systematic error estimation and track fusion are achieved. Simulation results verify that this method can get accurate estimation of systematic error and state vector.

  11. Centralization or decentralization of technology information: future cooperation or competition

    Rivera, E.

    1982-01-01

    Although advocates of decentralization cite the values of individual privacy, human dimensions, and potential for creativity and innovation, the advent of microcomputer technology during the past five years brought the first real reversal of the trend toward centralization. Both systems have their economic, social, and technical consequences. Centralization, for example, has the advantages of scale economy, coordination, and the control of lower-level activities to meet higher-level goals. At issue are the problems of sharing and data distribution. A hybridism of systems will take place in the next five years along with a conversion to smaller, more-flexible and personal systems as microprocessors come down in price. Application will determine the extent of centralization for each system. The shift will affect education, international forums, the type of work conducted in the service sector, and life styles, and will introduce legal, political, and organizational problems. 7 references.

    Decentralized biomass processing facilities, known as biomass depots, may be necessary to achieve feedstock cost, quantity, and quality required to grow the future U.S. bioeconomy. In this paper, we assess three distinct depot configurations for technical difference and economic performance. The depot designs were chosen to compare and contrast a suite of capabilities that a depot could perform ranging from conventional pelleting to sophisticated pretreatment technologies. Our economic analyses indicate that depot processing costs are likely to range from ∼US$30 to US$63 per dry metric tonne (Mg), depending upon the specific technology implemented and the energy consumption for processing equipment such as grinders and dryers. We conclude that the benefits of integrating depots into the overall biomass feedstock supply chain will outweigh depot processing costs and that incorporation of this technology should be aggressively pursued.

    Martin, C. F.

    1982-01-01

    Certain fundamental structures associated with linear systems having internal symmetries are outlined. It is shown that the theory of finite-dimensional algebras and their representations are closely related to such systems. It is also demonstrated that certain problems in the decentralized control of symmetric systems are equivalent to long-standing problems of linear systems theory. Even though the structure imposed arose in considering the problems of twin-lift helicopters, any large system composed of several identical intercoupled control systems can be modeled by a linear system that satisfies the constraints imposed. Internal symmetry can be exploited to yield new system-theoretic invariants and a better understanding of the way in which the underlying structure affects overall system performance.

    2014-04-15

    This paper presents transient stability improvement by a new distributed hierarchical control architecture (DHC). The integration of remedial action schemes (RAS) to the distributed hierarchical control architecture is studied. RAS in power systems are designed to maintain stability and avoid undesired system conditions by rapidly switching equipment and/or changing operating points according to predetermined rules. The acceleration trend relay currently in use in the US western interconnection is an example of RAS that trips generators to maintain transient stability. The link between RAS and DHC is through fast acting robust turbine/governor control that can also improve transient stability. In this paper, the influence of the decentralized robust turbine/governor control on the design of RAS is studied. Benefits of combining these two schemes are increasing power transfer capability and mitigation of RAS generator tripping actions; the later benefit is shown through simulations.

    Full Text Available Thermal Storages and Thermal Accumulators are an important component within District Heating (DH systems, adding flexibility and offering additional business opportunities for these systems. Furthermore, these components have a major impact on the energy and exergy efficiency as well as the heat losses of the heat distribution system. Especially the integration of Thermal Storages within ill-conditioned parts of the overall DH system enhances the efficiency of the heat distribution. Regarding an illustrative and simplified example for a DH system, the interactions of different heat storage concepts (centralized and decentralized and the heat losses, energy and exergy efficiencies will be examined by considering the thermal state of the heat distribution network.

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    A state-dependent routing algorithm based on the neural network model, which takes advantage of other dynamic routing algorithm for circuit-switched network, is given in [1]. But, the Algorithm in [1] is a centralized control model with complex O (N7), therefore, is difficult to realize by hardware. A simplified algorithm is put forward in this paper, in which routing can be controlled decentralizedly, and its complexity is reduced to O (10N3). Computer simulations are made in a fully connected test network with eight nodes. The results show that the centralized control model has very effective performance that can match RTNR, and the centralized control model is not as good as the centralized one but better than DAR-1.

    Full Text Available Droop schemes are usually applied to the control of distributed generators (DGs in microgrids (MGs to realize proportional power sharing. The objective might, however, not suit MGs well for economic reasons. Addressing that issue, this paper proposes an alternative droop scheme for reducing the total active generation costs (TAGC. Optimal economic operation, DGs’ capacity limitations and system stability are fully considered basing on DGs’ generation costs. The proposed scheme utilizes the frequency as a carrier to realize the decentralized economic operation of MGs without communication links. Moreover, a fitting method is applied to balance DGs’ synchronous operation and economy. The effectiveness and performance of the proposed scheme are verified through simulations and experiments.

    2009-01-01

    In this paper,we investigate the locally and globally adaptive synchronization problem for an uncertain complex dynamical network with time-varying coupling delays based on the decentralized control.The coupling terms here are bounded by high-order polynomials with known gains that are ubiquitous in a large class of complex dynamical networks.We generalize the usual technology of searching for an appropriate coordinates transformation to change the network dynamics into a series of decoupled lower-dimensional systems.Several adaptive synchronization criteria are derived by constructing the Lyapunov-Krasovskii functional and Barbalat lemma,and the proposed criteria are simple in form and convenient for the practical engineering design.Numerical simulations illustrated by a nearest-neighbor coupling network verify the effectiveness of the proposed synchronization scheme.

    2012-01-01

    The dynamic provisioning of virtualized resources offered by cloud computing infrastructures allows applications deployed in a cloud environment to automatically increase and decrease the amount of used resources. This capability is called auto-scaling and its main purpose is to automatically adjust the scale of the system that is running the application to satisfy the varying workload with minimum resource utilization. The need for auto-scaling is particularly important during workload peaks, in which applications may need to scale up to extremely large-scale systems. Both the research community and the main cloud providers have already developed auto-scaling solutions. However, most research solutions are centralized and not suitable for managing large-scale systems, moreover cloud providers' solutions are bound to the limitations of a specific provider in terms of resource prices, availability, reliability, and connectivity. In this paper we propose DEPAS, a decentralized probabilistic auto-scaling algorit...

    2015-03-01

    Full Text Available As in other aspects of society (politics, economics, the film industry appears to be undergoing a process of decentralization (still in its infancy by which Asia is, if not overtaking, at least matching its level of influence with that of European and American powers. Much of the impetus shifting this balance corresponds to China. The spectacular growth of China‟s domestic market is concentrating a substantial part of the global film business within this Asian giant, resulting in the still sector leader, the United States, conditioning its production in order to maximize profits in that territory. Resolute internationalization policies are also helping Chinese companies gain a foothold in Western countries conditioning film content there, although paradoxically their audiences remain unwilling to consume cinema that is culturally foreign. This essay will attempt to explain how all this has occurred.

    Full Text Available Decentred Centre in John Fowles’sThe Magus Abstract John Fowles’ The Magus (1966 has been the focus of criticism for many years. This study regards the character of Conchis as a decentred “centre” in the structure of the novel and as in the experience of the contemporary humanity. Conchis becomes in the eyes of Nicholas an all-knowing figure, an accumulation of Western thought since the Greek civilization. He produces signs to be read as he himself becomes a body of various signs that construct him as the metaphysical centre that Western thinkers have relied upon. His narration becomes superior to Nicholas’ and he himself becomes only a narrative voice. The voice from the times of Plato has been considered as a direct expression of the thoughts in one’s mind and thus superior to writing that is permeated with the undecidability of meaning in the absence of the speaker and the addressee. In the novel, words as an endless play of metaphors take the place of voice. There is no knowable reality outside the play words or metaphors which is an endless chain of signifiers that lead to other signifiers. Every time Nicholas turns to Conchis to find the centre outside the play of the language, he finds other signifiers. Thus, Conchis as a meaning-making centre is dethroned. He is not the sole operator of the masks that divert from their presumed original target when they are read. Nicholas is just another production of the literary tradition who reads the signs only to produce other signs. Conchis in the beginning of the novel renounces fiction for science but along the course of the novel, we see that words are never reliable whether in fiction or in science.

  3. Towards a personalized Internet: a case for a full decentralization.

    Kermarrec, Anne-Marie

    2013-03-28

    The Web has become a user-centric platform where users post, share, annotate, comment and forward content be it text, videos, pictures, URLs, etc. This social dimension creates tremendous new opportunities for information exchange over the Internet, as exemplified by the surprising and exponential growth of social networks and collaborative platforms. Yet, niche content is sometimes difficult to retrieve using traditional search engines because they target the mass rather than the individual. Likewise, relieving users from useless notification is tricky in a world where there is so much information and so little of interest for each and every one of us. We argue that ultra-specific content could be retrieved and disseminated should search and notification be personalized to fit this new setting. We also argue that users' interests should be implicitly captured by the system rather than relying on explicit classifications simply because the world is by nature unstructured, dynamic and users do not want to be hampered in their actions by a tight and static framework. In this paper, we review some existing personalization approaches, most of which are centralized. We then advocate the need for fully decentralized systems because personalization raises two main issues. Firstly, personalization requires information to be stored and maintained at a user granularity which can significantly hurt the scalability of a centralized solution. Secondly, at a time when the 'big brother is watching you' attitude is prominent, users may be more and more reluctant to give away their personal data to the few large companies that can afford such personalization. We start by showing how to achieve personalization in decentralized systems and conclude with the research agenda ahead.

  4. Generic, scalable and decentralized fault detection for robot swarms

    Christensen, Anders Lyhne; Timmis, Jon

    2017-01-01

    Robot swarms are large-scale multirobot systems with decentralized control which means that each robot acts based only on local perception and on local coordination with neighboring robots. The decentralized approach to control confers number of potential benefits. In particular, inherent scalability and robustness are often highlighted as key distinguishing features of robot swarms compared with systems that rely on traditional approaches to multirobot coordination. It has, however, been shown that swarm robotics systems are not always fault tolerant. To realize the robustness potential of robot swarms, it is thus essential to give systems the capacity to actively detect and accommodate faults. In this paper, we present a generic fault-detection system for robot swarms. We show how robots with limited and imperfect sensing capabilities are able to observe and classify the behavior of one another. In order to achieve this, the underlying classifier is an immune system-inspired algorithm that learns to distinguish between normal behavior and abnormal behavior online. Through a series of experiments, we systematically assess the performance of our approach in a detailed simulation environment. In particular, we analyze our system’s capacity to correctly detect robots with faults, false positive rates, performance in a foraging task in which each robot exhibits a composite behavior, and performance under perturbations of the task environment. Results show that our generic fault-detection system is robust, that it is able to detect faults in a timely manner, and that it achieves a low false positive rate.

    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.

    Decentralized energy systems and their characteristic features are examined in the report. These systems have been divided into six groups for the purpose of analysis: solar, wind, hydro, biomass, geothermal, and coproduction (total energy). The technical and economic potential for the implementation of these systems is discussed for the years 2000 and 2025. The results of a comparison of base-case and decentralized scenarios for the year 2000, using a computer systems model, are presented. Social and institutional factors are also addressed, both as motivations for and results of energy system decentralization. Appendices are included with more detailed technical information on each of the systems groups.

    Decentralized H∞ control was studied for a class of interconnected uncertain systems with multiple delays in the state and control and time varying but norm-bounded parametric uncertainties. A sufficient condition which makes the closed--loop system decentralized asymptotically stable with H∞ performance was derived based on Lyapunov stability theorem. This condition is expressed as the solvability problem of linear matrix inequalities. The method overcomes the limitations of the existing algebraic Riccati equation method. Finally, a numerical example was given to demonstrate the design procedure for the decentralized H∞ state feedback controller.

    Abstract Relational maintenance is connected to high quality friendships. Friendship maintenance behaviors may occur online via social networking sites. This study utilized an Actor-Partner Interdependence Model to examine how Facebook maintenance and surveillance affect friendship quality. Bryant and Marmo's (2012) Facebook maintenance scale was evaluated, revealing two factors: sharing and caring. Facebook surveillance was also measured. For friendship satisfaction and liking, significant positive actor and partner effects emerged for caring; significant negative actor, partner, and interaction effects emerged for sharing; and significant positive actor effects emerged for surveillance. For friendship closeness, significant positive actor effects emerged for caring and surveillance.

    Full Text Available This article tries to fulfil the research gap left by the fact that no study to date has examined how trust in social actors affects attitudes towards genetically modified organisms (GMOs. Therefore, two key hypotheses were posited: a trust in social actors is a more important factor of attitudes towards GMOs than knowledge about GMOs; and b trust in certain social actors is a more important factor than trust in other social actors. Telephone survey data of adult Slovenians were used. The analyses show that: a general trust in social actors has a positive effect on attitudes towards GMOs; b trust in various social actors has different effects; and c trust in social actors has a stronger effect on attitudes towards GMOs than knowledge about GMOs.

    Full Text Available The article is a result of research of role played by an international public associa­tion “Internet Engineering Task Force” in international Internet governance sys­tem. The object of the research is a process of construction of a system of institu­tions which coordinate development of Internet. In the article, potential of non­governmental actors in this area is assessed. The article highlights causes and possi­ble effects of IETF activities as the most highly respected nongovernmental associa­tions which try to solve one of the urgent problems of world politics – transforma­tion of an existing approach to Internet governance. IETF approach is compared with approaches of other nongovernmental organizations and public associations such as ICANN, W3C and WaSP. The conclusion is made that authority of IETF in the community of Internet projects developers enables this public association to de­fine the key characteristics of technological policy in Internet evolution. Thus, IETF is considered as one of the key actors of international system of Internet gover­nance. Also, the importance of IETF-like associations has been underestimated by governmental actors yet. This underestimation determines Russian, Chinese and Iranian attacks on ICANN. These states support a project of full internationaliza­tion of Internet governance and consider ICANN as an organization which controls the Internet for the benefit of the United States of America.DOI: http://dx.doi.org/10.12731/2218-7405-2013-8-28

    The Terrorist Radicalization Assessment Protocol (TRAP-18) is a structured professional judgment instrument for the assessment of individuals who present a concern for lone-actor terrorism. It consists of eight proximal warning behaviors and 10 distal characteristics. Previous research has demonstrated its interrater reliability and some concurrent and postdictive validity. In this article, TRAP-18 is retrospectively applied to the case of US Army psychiatrist and jihadist Malik Nidal Hasan, who committed a mass murder at Fort Hood, Texas in 2009. The strengths and limitations of TRAP-18 as a structured professional judgment instrument for mental health clinicians are discussed, and clinical risk management suggestions are made.

    Institute of Scientific and Technical Information of China (English)

    李元春; 丁贵彬; 赵博

    2016-01-01

    A decentralized adaptive neural network sliding mode position/force control scheme is proposed for constrained reconfigurable manipulators. Different from the decentralized control strategy in multi-manipulator cooperation, the proposed decentralized position/force control scheme can be applied to series constrained reconfigurable manipulators. By multiplying each row of Jacobian matrix in the dynamics by contact force vector, the converted joint torque is obtained. Furthermore, using desired information of other joints instead of their actual values, the dynamics can be represented as a set of interconnected subsystems by model decomposition technique. An adaptive neural network controller is introduced to approximate the unknown dynamics of subsystem. The interconnection and the whole error term are removed by employing an adaptive sliding mode term. And then, the Lyapunov stability theory guarantees the stability of the closed-loop system. Finally, two reconfigurable manipulators with different configurations are employed to show the effectiveness of the proposed decentralized position/force control scheme.

    1993-09-01

    Brazilian society is beginning a new historical period in which the principle of decentralization is beginning to predominate over centralization, which held sway during the last 25 years. In contrast to recent Brazilian history, there is now a search for political, democratic and participatory decentralization more consonant with grass-roots aspirations. The first section of this article presents a brief analysis of some decentralization policies implemented by the military regime of 1964, and discusses relevant facts related to the resistance of civil society to state authoritarianism, and to the struggle for the democratization and organization of civil society up to the end of the 1970s. The second section analyzes some new experiences of democratic public school administration initiated in the 1970s and 1980s. The final section discusses the move toward decentralization and democratization of public school administration in the new Federal and State Constitutions, and in the draft of the new Law of National Education.

  3. The Politics of Fiscal Decentralization Revisited: a Typology and Comparative Evidence

    2009-06-01

    Full Text Available Although the practice of fiscal decentralization is worldwide and its implementation and effects vary from country to country, its political significance has been often neglected, or worse, treated as implicit to decentralization. This study considers the sources of politicization of fiscal decentralization, focusing on the determination and manipulation of intergovernmental transfers. It develops a new index of fiscal politicization and proposes an explanatory typology that takes into account subnational transfer dependency and the extent to which transfers are politically determined. This analysis renders a conceptual tool that captures nuanced facts about the intergovernmental level of conflict to a larger extent than conventional measures of fiscal decentralization do. We found that the effects of fiscal dependency are intertwined with political asymmetries derived from legislative overrepresentation of territorial units and intergovernmental bargaining strategies.

  5. Multisensor Fault Identification Scheme Based on Decentralized Sliding Mode Observers Applied to Reconfigurable Manipulators

    Directory of Open Access Journals (Sweden)

    Bo Zhao

    2013-01-01

    Full Text Available This paper concerns with a fault identification scheme in a class of nonlinear interconnected systems. The decentralized sliding mode observer is recruited for the investigation of position sensor fault or velocity sensor fault. First, a decentralized neural network controller is proposed for the system under fault-free state. The diffeomorphism theory is utilized to construct a nonlinear transformation for subsystem structure. A simple filter is implemented to convert the sensor fault into pseudo-actuator fault scenario. The decentralized sliding mode observer is then presented for multisensor fault identification of reconfigurable manipulators based on Lyapunov stable theory. Finally, two 2-DOF reconfigurable manipulators with different configurations are employed to verify the effectiveness of the proposed scheme in numerical simulation. The results demonstrate that one joint’s fault does not affect other joints and the sensor fault can be identified precisely by the proposed decentralized sliding mode observer.

    Decentralized solar technology and centralized electric utilities were contrasted in the ways they assign property rights in capital and energy output; in the assignment of operational control; and in the means of monitoring, policing, and enforcing property rights. An analogy was drawn between the decision of an energy consumer to use decentralized solar and the decision of a firm to vertically integrate, that is, to extend the boundary of a the firm to vertically integrate, that is, to extend the boundary of the firm by making inputs or further processing output. Decentralized solar energy production offers the small energy consumer the chance to cut ties to outside suppliers--to vertically integrate energy production into the home or business. The development of this analogy provides insight into important noneconomic aspects of solar energy, and it points clearly to the lighter burdens of social management offered by decentralized solar technology.

    This paper is a product of the reflection on the decentralization and sectorization experiences in Mexico since 1917 with particular emphasis on the 1980s. The historical analysis included the creation of an analytical model designed to identify the relationship between the distinct sanitary policies implemented in Mexico and the tendencies towards decentralization and integration. This analysis is combined with a critical review of the recent decentralization experiences undertaken in the states of Guerrero, Oaxaca and Nuevo León. While comparing Guerrero and Oaxaca, restitution and deconcentration under similar socio-economic conditions were discussed. The comparison between Guerrero and Nuevo Leon allowed the discussion of the benefits and limits of restitution under different socio-economic conditions. In addition, with this model the author discusses a few generalizations regarding the possible future of decentralization.

    Due to the significant environmental impact of power production from fossil fuels and nuclear fission, future energy systems will increasingly rely on distributed and renewable energy sources (RES). The electrical feed-in from photovoltaic (PV) systems and wind energy converters (WEC) varies greatly both over short and long time periods (from minutes to seasons), and (not only) by this effect the supply of electrical power from RES and the demand for electrical power are not per se matching. In addition, with a growing share of generation capacity especially in distribution grids, the top-down paradigm of electricity distribution is gradually replaced by a bottom-up power supply. This altogether leads to new problems regarding the safe and reliable operation of power grids. In order to address these challenges, the notion of Smart Grids has been introduced. The inherent flexibilities, i.e. the set of feasible power schedules, of distributed power units have to be controlled in order to support demand–supply matching as well as stable grid operation. Controllable power units are e.g. combined heat and power plants, power storage systems such as batteries, and flexible power consumers such as heat pumps. By controlling the flexibilities of these units we are particularly able to optimize the local utilization of RES feed-in in a given power grid by integrating both supply and demand management measures with special respect to the electrical infrastructure. In this context, decentralized systems, autonomous agents and the concept of self-organizing systems will become key elements of the ICT based control of power units. In this contribution, we first show how a decentralized load management system for battery charging/discharging of electrical vehicles (EVs) can increase the locally used share of supply from PV systems in a low voltage grid. For a reliable demand side management of large sets of appliances, dynamic clustering of these appliances into uniformly

    Full Text Available This paper examines the dual-channel supply chain in which the differentiation of the environmental sustainability of channels is considered. We analyze the influences of the level of environmental sustainability of channels on the pricing policies for the supply chain members in both centralized and decentralized models using the Stackelberg game model under inconsistent price policy. We obtain the optimal level of environmental sustainability of channels and pricing decisions for the players in the centralized and decentralized dual-channel supply chains. Results show that the influence mechanisms of the level of environmental sustainability of channels on the pricing decisions are different in the centralized and decentralized models. Furthermore, numerical analysis has been conducted to investigate the effects of the cross-environmental-sustainability sensitivity factor and the initial proportion of consumers who prefer the retail channel on the level of environmental sustainability of channels, pricing policies and players’ profits.

    drinking water, but negative consequences for the ecological quality and biodiversity. In the 1980s environmental awareness increased. To restore natural processes, it was decided in 2000 to put the sluices 'ajar' as a first step towards the strategic long-term vision of tidal restoration and major rehabilitation of the Rhine-Meuse estuary. First planning was to have the Kierbesluit implemented in 2005. However, this has been put off again and again, and since the actual implementation started in 2013, planning is to have the infrastructures ready to start opening the sluices in 2018 - 13 years later. What was supposed to be the first step towards full estuarine recovery has become an end goal itself, with implementing actors strictly focusing on putting the sluices ajar and compensating for fresh water loss, dismissing building with nature possibilities behind the dam. The Advocacy Coalition Framework is used as a starting point for analysis, and will be altered and detailed with insights from implementation literature to identify lessons regarding the role and dynamics of actor coalitions from the planning to implementation stage of strategic delta planning.

We obtain sufficient stability conditions for interconnected systems which are equivalent to disturbance attenuation of some scaled system. A decentralized output-feedback controller is obtained using standard H{infinity} control theory. The obtained controller is delay-independent. We also obtain an observer for the interconnected system. (author). 9 refs.

  13. Decentralization's impact on the health workforce: Perspectives of managers, workers and national leaders

    Directory of Open Access Journals (Sweden)

    Kolehmainen-Aitken Riitta-Liisa

    2004-05-01

    Full Text Available Abstract Designers and implementers of decentralization and other reform measures have focused much attention on financial and structural reform measures, but ignored their human resource implications. Concern is mounting about the impact that the reallocation of roles and responsibilities has had on the health workforce and its management, but the experiences and lessons of different countries have not been widely shared. This paper examines evidence from published literature on decentralization's impact on the demand side of the human resource equation, as well as the factors that have contributed to the impact. The elements that make such an impact analysis exceptionally complex are identified. They include the mode of decentralization that a country is implementing, the level of responsibility for the salary budget and pay determination, and the civil service status of transferred health workers. The main body of the paper is devoted to examining decentralization's impact on human resource issues from three different perspectives: that of local health managers, health workers themselves, and national health leaders. These three groups have different concerns in the human resource realm, and consequently, have been differently affected by decentralization processes. The paper concludes with recommendations regarding three key concerns that national authorities and international agencies should give prompt attention to. They are (1 defining the essential human resource policy, planning and management skills for national human resource managers who work in decentralized countries, and developing training programs to equip them with such skills; (2 supporting research that focuses on improving the knowledge base of how different modes of decentralization impact on staffing equity; and (3 identifying factors that most critically influence health worker motivation and performance under decentralization, and documenting the most cost-effective best
