    This is the final report with respect to work commissioned by the Department of Trade and Industry (DTI) as part of the New and Renewable Energy Programme into incentives for distribution network operators (DNOs) for the connection of embedded generation. This report, which incorporates the contents of the interim report submitted in February 2002, considers the implications of changes in the structure and regulation in the UK electricity industry on the successful technical and commercial integrated of embedded generation into distribution networks. The report examines: the obligations of public electricity suppliers (PESs); current DNO practices regarding the connection of embedded generation; the changes introduced by the Utilities Act 2000, including the impact of new obligations placed on DNOs on the connection of embedded generation and the requirements of the new Electricity Distribution Standard Licence conditions; and problems and prospects for DNO incentives.

    2014-11-01

    Full Text Available Renewable DGs may not be economically viable due to the stochastic generation and huge capital investment, but are an inevitable choice for sustainable energy development and future planning. An appropriate incentive scheme for clean Distributed Generation (DG technologies is able to address this issue in an economical manner and is considered in proposed distributed generation planning model. The proposed model minimizes the annualized cost with Emission Offset Incentive (EOI and the penalty for Green-house Gas (GHG emissions. A meta-heuristic approach with dynamic tuning of control parameters is adopted to improve the success and the convergence rate of optimal solutions. The algorithm provides the optimal solution in terms of type, size, and location of DG. The proposed technique is implemented on IEEE 33-bus system. Proposed model helps the Distribution Network Operators (DNOs to decide the proper DG technology from an economic prospective for eco-friendly energy planning.

    The connection and distribution of growing, decentralized electricity generation from renewable energy sources (RES-E) is leading to massive investment needs. Besides investing in additional ‘conventional’ assets (e.g. cables), grid operators can also invest in innovative ‘smart solutions’ like local storage capacities or voltage regulation appliances, which may be a more suitable way of integrating RES-E. This paper investigates the influence of incentive regulation on the investment decision of grid operators to integrate RES-E. We describe the technical and regulatory background, explain the advantages of ‘smart solutions’ and present an approach for comparing investment scenarios. As an example, we calculate the profitability of investments in a case study of the German electricity market. We apply Data Envelopment Analysis (DEA) and Stochastic Frontier Analysis (SFA) to show the influence of the investment alternatives on grid operator efficiency objectives. We demonstrate that under current ‘standard’ incentive regulation, the grid operators gain profitability by avoiding investments and – if they are forced to invest – by not implementing ‘smart solutions’. The results highlight the need to consider innovation in the regulation design. Further research should investigate specific instruments that can be used to account for innovation. Our brief discussion of such instruments provides a starting point. - Highlights: ► We measure the influence of investments on efficiency by applying DEA and SFA. ► We compare the profitability of alternative investments under incentive regulation. ► Incentive regulation gives incentives to refuse investment at all. ► If DSOs are forced to invest, reinforcement is preferable to smart solutions. ► Ways to consider innovation in incentive regulations are required and discussed.

    Alternative Energy Generation Sources are turning relevant in several countries worldwide because of technology improvement and the environmental treatment. In this paper, the most common problems of renewable energy sources are accomplished, different incentives and regulatory mandates from several countries are exposed, and a first theoretical approach to a renewable energies incentive system in Colombia is discussed. The paper is fundamentally in theoretical aspects and international experience in renewable energies incentives to accelerate their diffusion; features are analyzed towards a special incentive system for renewable energies in Colombia. As a conclusion, in Colombia will be apply indirect incentives like low interest rate, taxes exemptions and so on. But these incentives are applied to limit the support of electricity productivity in generating organizations.

    2013-04-01

    This is a report on generation-specific incentives and disincentives selected by acute care nurses that promote and discourage them to remain employed in hospitals. Recent literature indicates that nurse preferences for strategies to promote their retention may differ across generational cohorts. However, current literature is primarily anecdotal with few studies focused on evidence-based generation-specific nurse retention-promoting strategies. Data were gathered from a cross-sectional survey administered to a random sample of 9904 registered nurses working in Alberta and Ontario, Canada. Two survey items asking nurses to identify preferences for incentives to remain employed and disincentives that encourage them to leave employment were included. Survey items were based on information gathered from previous focus groups exploring determinants of nurse retention. There were statistically significant differences in the rates of selection across generations of nurses for eight of 10 incentives to remain employed and for eight of 15 disincentives. All generational cohorts selected the same two incentives most frequently: reasonable workloads and manageable nurse-patient ratios. Two of the three most frequently selected disincentives were the same across generations: inadequate staffing and unmanageable workloads. Leaders should implement and evaluate strategies that ensure workloads are reasonable and nurse-patient ratios are manageable to promote retention among all generations of nurses in the acute care hospital workforce. © 2012 Blackwell Publishing Ltd.

  11. Examination of incentive mechanisms for innovative technologies applicable to utility and nonutility power generators

    Innovative technologies, built by either utility or nonutility power generators, have the potential to lower costs with less environmental emissions than conventional technologies. However, the public-good nature of information, along with uncertain costs, performance, and reliability, discourages rapid adoption of these technologies. The effect of regulation of electricity production may also have an adverse impact on motivation to innovate. Slower penetration of cleaner, more efficient technologies could result in greater levels of pollution, higher electricity prices, and a reduction in international competitiveness. Regulatory incentives could encourage adoption and deployment of innovative technologies of all kinds, inducting clean coal technologies. Such incentives must be designed to offset risks inherent in innovative technology and encourage cost-effective behavior. To evaluate innovative and conventional technologies equally, the incremental cost of risk (ICR) of adopting the innovative technology must be determined. Through the ICR, the magnitude of incentive required to make a utility (or nonutility) power generator equally motivated to use either conventional or innovative technologies can be derived. Two technology risks are examined: A construction risk, represented by a 15% cost overrun, and an operating risk, represented by a increased forced outage rate (decreased capacity factor). Different incentive mechanisms and measurement criteria are used to assess the effects of these risks on ratepayers and shareholders. In most cases, a regulatory incentive could offset the perceived risks while encouraging cost-effective behavior by both utility and nonutility power generators. Not only would the required incentive be recouped, but the revenue requirements would be less for the innovative technology; also, less environmental pollution would be generated. In the long term, ratepayers and society would benefit from innovative technologies.

    The past two decades have seen remarkable advances in photo-realistic rendering of everything from inanimate objects to landscapes, animals, and humans. We previously showed that despite these tremendous advances, human observers remain fairly good at distinguishing computer-generated from photographic images. Building on these results, we describe a series of follow-up experiments that reveal how to improve observer performance. Of general interest to anyone performing psychophysical studies on Mechanical Turk or similar platforms, we find that observer performance can be significantly improved with the proper incentives.

  14. Do generation firms in restructured electricity markets have incentives to support social-welfare-improving transmission investments?

    Sauma, Enzo E.; Oren, Shmuel S.

    2009-01-01

    This paper examines the incentives that generation firms have in restructured electricity markets for supporting long-term transmission investments. In particular, we study whether generation firms, which arguably play a dominant role in the restructured electricity markets, have the incentives to fund or support incremental social-welfare-improving transmission investments. We examine this question in a two-node network and explore how such incentives are affected by the ownership of financial transmission rights (FTRs) by generation firms. In the analyzed two-node network, we show both (1) that the net exporter generation firm has the correct incentives to increase the transmission capacity incrementally up to a certain level and (2) that, although a policy that allocates FTRs to the net exporter generation firm can be desirable from a social point of view, such a policy would dilute the net-importer-generation-firm's incentives to support transmission expansion. Moreover, if all FTRs were allocated or auctioned off to the net exporter generation firm, then it is possible to increase both consumer surplus and social welfare while keeping the net exporter generation firm revenue neutral.

    The aims of this paper are to: (1) describe work characteristics that nurse faculty report encourage them to remain in or leave their academic positions; and (2) determine if there are generational differences in work characteristics selected. Nurse faculty play key roles in preparing new nurses and graduate nurses. However, educational institutions are challenged to maintain full employment in faculty positions. A cross-sectional, descriptive survey design was employed. Ontario nurse faculty were asked to select, from a list, work characteristics that entice them to remain in or leave their faculty positions. Respondent data (n = 650) were collected using mailed surveys over four months in 2011. While preferred work characteristics differed across generations, the most frequently selected incentives enticing nurse faculty to stay were having: a supportive director/dean, reasonable workloads, supportive colleagues, adequate resources, manageable class sizes and work/life balance. The most frequently selected disincentives included: unmanageable workloads, unsupportive organizations, poor work environments, exposure to bullying, belittling and other types of incivility in the workplace and having an unsupportive director/dean. This research yields new and important knowledge about work characteristics that nurse faculty report shape their decisions to remain in or leave their current employment. Certain work characteristics were rated as important among all generations. Where similarities exist, broad strategies addressing work characteristics may effectively promote nurse faculty retention. However, where generational differences exist, retention-promoting strategies should target generation-specific preferences. © 2014 John Wiley & Sons Ltd.

    Taxation policy and incentives play a vital role in wind-based distributed generation projects viability. In this paper, a thorough techno-economical evaluation of wind-based distributed generation projects is conducted to investigate the effect of taxes and incentives in the economic viability of investments in this sector. This paper considers the effects of Provincial income taxes, capital cost allowance (CCA), property taxes, and wind power production Federal incentives. The case study is conducted for different wind turbines and wind speed scenarios. Given turbine and wind speed data, the Capacity Factor (CF) of each turbine and wind speed scenario was calculated. Net Present Value (NPV) and Internal Rate of Return (IRR) for different scenarios were then used to assess the project's viability considering Ontario Standard Offer Program (SOP) for wind power.

  18. Will the use of a carbon tax for revenue generation produce an incentive to continue carbon emissions?

    Science.gov (United States)

    Wang, Rong; Moreno-Cruz, Juan; Caldeira, Ken

    2017-05-01

    Integrated assessment models are commonly used to generate optimal carbon prices based on an objective function that maximizes social welfare. Such models typically project an initially low carbon price that increases with time. This framework does not reflect the incentives of decision makers who are responsible for generating tax revenue. If a rising carbon price is to result in near-zero emissions, it must ultimately result in near-zero carbon tax revenue. That means that at some point, policy makers will be asked to increase the tax rate on carbon emissions to such an extent that carbon tax revenue will fall. Therefore, there is a risk that the use of a carbon tax to generate revenue could eventually create a perverse incentive to continue carbon emissions in order to provide a continued stream of carbon tax revenue. Using the Dynamic Integrated Climate Economy (DICE) model, we provide evidence that this risk is not a concern for the immediate future but that a revenue-generating carbon tax could create this perverse incentive as time goes on. This incentive becomes perverse at about year 2085 under the default configuration of DICE, but the timing depends on a range of factors including the cost of climate damages and the cost of decarbonizing the global energy system. While our study is based on a schematic model, it highlights the importance of considering a broader spectrum of incentives in studies using more comprehensive integrated assessment models. Our study demonstrates that the use of a carbon tax for revenue generation could potentially motivate implementation of such a tax today, but this source of revenue generation risks motivating continued carbon emissions far into the future.

  19. Incentives to Build New Generation on Competitive Electricity Markets. Conference proceedings

    International Nuclear Information System (INIS)

    2007-06-01

    The need for new investments in power generation is paramount all over the world. It has been calculated that only in Europe, there is a need of investments in the electricity sector of around 1,000,000 billion EURs during the next decade. High prices on primary energy, security of supply issues regarding imported fuels and a steadily growing concern about climate changes put an extra restrain on supply options for the future. To meet these challenges politicians, at least in Europe, try out new support schemes and other policy measures as full scale experiments. These policy measures sometimes interact very badly with competitive electricity markets. Some will argue that most of the problems we are facing have very little to do with the design of electricity markets and that the solution to the issue is not necessarily to enforce a tight regulation on the industry. But this said, the issue is so important to society that even we who like competition and have been working hard this last decade to make competitive electricity markets perform well, must be prepared to rethink. This conference once again gathers people from many different parts of the world to exchange ideas and experiences from their respective area of operations. There are four main topics for the Conference: The impact from emission trading programs; Renewable portfolio standards; Nuclear plans and distributed generation incentives; and Capacity payment and/or reserve requirements. (Five papers presented at the conference have been indexed separately. Powerpoint presentations have not been indexed but are available from the Market Design homepage)

    Generating language that reflects the temporal organization of represented knowledge requires a language generation model that integrates contemporary theories of tense and aspect, temporal representations, and methods to plan text. This paper presents a model that produces complex sentences that reflect temporal relations present in underlying temporal concepts. The main result of this work is the successful application of constrained linguistic theories of tense and aspect to a generator which produces meaningful event combinations and selects appropriate connecting words that relate them.

    Kai, Takaaki; Tanaka, Yuji; Kaneda, Hirotoshi; Kobayashi, Daichi; Tanaka, Akio

    Recently, doubly fed induction generator (DFIG) and synchronous generator are mostly applied for wind power generation due to high efficiently for wind energy capture. An inverter system is required to control wind turbine speed and power factor in those generators. The inverter rating of the synchronous generator equals to generator rating. However, DFIG has the advantage that the inverter rating is about 25% to the generator rating. The paper describes a vector control of DFIG inter-connected to power line. The performance of proposed vector control is examined using power system simulation software PSCAD/EMTDC for the DFIG inter-connected to 6.6kv distribution line. The results show good dynamic responses and high accuracy to the stator active power control and the stator reactive power control.

    Kai, Takaaki; Tanaka, Yuji; Kaneda, Hirotoshi; Kobayashi, Daichi; Tanaka, Akio

    Recently, doubly fed induction generator (DFIG) and synchronous generator are mostly applied for wind power generation, and variable speed control and power factor control are executed for high efficiently for wind energy capture and high quality for power system voltage. In variable speed control, a wind speed or a generator speed is used for maximum power point tracking. However, performances of a wind generation power fluctuation due to wind speed variation have not yet investigated for those controls. The authors discuss power smoothing by those controls for the DFIG inter-connected to 6.6kV distribution line. The performances are verified using power system simulation software PSCAD/EMTDC for actual wind speed data and are examined from an approximate equation of wind generation power fluctuation for wind speed variation.

    International Nuclear Information System (INIS)

    Hill, L.J.; Hadley, S.W.

    In this paper, we estimate the effects of current federal tax policy on the financial criteria that investor-owned electric utilities (IOUs) and non-utility electricity generators (NUGs) use to evaluate wood-fuel electric-generating technologies, distinguishing between dedicated-plantation and wood-waste fuels. Accelerated tax depreciation, the 1.5 cent/kWh production tax credit for the dedicated-plantation technology, and the alternative minimum tax are the most important tax provisions. The results indicate that federal tax laws have significantly different effects on the evaluation criteria, depending on the plant's ownership (IOU vs NUG) and type of fuel (dedicated-plantation vs wood-waste).

    This article relates to research on the cost effectiveness of the MEP scheme ('Milieukwaliteit Elektriciteitsproductie' or Environmental Quality of Electricity Generation), carried out as a graduation project at the Vrije Universiteit, Amsterdam, Netherlands. MEP subsidies are intended to promote investment in sustainable energy sources in the Netherlands by offering investors more certainty and a simpler structure than previous energy subsidies. The MEP also helps prevent Dutch taxpayers' money 'leaking' abroad to purchase sustainable electricity produced cheaper elsewhere. This makes the MEP measurably more effective than its predecessors. The scheme is moreover a step towards the effective deployment of state funds for the reduction of CO2 emission [nl

    Distributed photovoltaic (PV) projects must go through an interconnection study process before connecting to the distribution grid. These studies are intended to identify the likely impacts and mitigation alternatives. In the majority of the cases, system impacts can be ruled out or mitigation can be identified without an involved study, through a screening process or a simple supplemental review study. For some proposed projects, expensive and time-consuming interconnection studies are required. The challenges to performing the studies are twofold. First, every study scenario is potentially unique, as the studies are often highly specific to the amount of PV generation capacity that varies greatly from feeder to feeder and is often unevenly distributed along the same feeder. This can cause location-specific impacts and mitigations. The second challenge is the inherent variability in PV power output which can interact with feeder operation in complex ways, by affecting the operation of voltage regulation and protection devices. The typical simulation tools and methods in use today for distribution system planning are often not adequate to accurately assess these potential impacts. This report demonstrates how quasi-static time series (QSTS) simulation and high time-resolution data can be used to assess the potential impacts in a more comprehensive manner. The QSTS simulations are applied to a set of sample feeders with high PV deployment to illustrate the usefulness of the approach. The report describes methods that can help determine how PV affects distribution system operations. The simulation results are focused on enhancing the understanding of the underlying technical issues. The examples also highlight the steps needed to perform QSTS simulation and describe the data needed to drive the simulations. The goal of this report is to make the methodology of time series power flow analysis readily accessible to utilities and others responsible for evaluating

    This paper presents a model that allows to evaluate the impact of distributed generation (DG) in the expansion of high voltage transmission grid. By applying the model it is possible to determine the size and location of small range generation that can grow incrementally, avoiding or delaying large investments in transmission lines. Whereas the cost of distributed generation for the system is associated with the cost of the incentives offered for that installation, it is also possible to determine the maximum value of this incentive to stimulate the installation of some quantity of DG that postponing the expansion of the transmission grid. The results show the need to consider explicitly the introduction of DG in the expansion planning since the impact it can have on the formation of tariffs for using the transmission system is meaningful.

    Full Text Available Simulator-independent descriptions of connectivity in neuronal networks promise greater ease of model sharing, improved reproducibility of simulation results, and reduced programming effort for computational neuroscientists. However, until now, enabling the use of such descriptions in a given simulator in a computationally efficient way has entailed considerable work for simulator developers, which must be repeated for each new connectivity-generating library that is developed.We have developed a generic connection generator interface that provides a standard way to connect a connectivity-generating library to a simulator, such that one library can easily be replaced by another, according to the modeller's needs. We have used the connection generator interface to connect C++ and Python implementations of the connection-set algebra to the NEST simulator. We also demonstrate how the simulator-independent modelling framework PyNN can transparently take advantage of this, passing a connection description through to the simulator layer for rapid processing in C++ where a simulator supports the connection generator interface and falling-back to slower iteration in Python otherwise. A set of benchmarks demonstrates the good performance of the interface.

    Public utility regulation lacks a formal proxy for the economic profits that can be earned in an effectively competitive market if a firm is efficient or innovative. After all, public utility regulation operated on cost-plus basis. If a utility is efficient or innovative and lowers its costs, its typical reward is to have its rates reduced. This is a perverse incentive to motivate a utility to produce at the most efficient level. In addition, since regulation operates on this cost-plus basis, a utility can increase its net income, all other things being equal, by overinvesting in (or open-quotes gold-platingclose quotes) its system, another perverse incentive. Recognizing these flaws of regulation, academicians, utility executives, regulators, and legislators have tried over the last several years to implement incentive regulation plans that correct such perverse incentives. However, under many of the earnings-sharing or price-regulation incentive plans, the rewards for efficient production are not tied directly to measures under a company's control. In fact, such plans could prove highly detrimental to ratepayers and competitors of the regulated company and its affiliates. An incentive regulation plan that ties an appropriate reward for efficient production to specific efficiency gains is a better proxy of an effectively competitive environment. What's more, it is superior to an incentive plan that rewards circumstances beyond the company's control or self-serving manipulation. This is particularly true if no earnings cap is associated with the reward for efficiency. Rewards for efficient production should be tied to specific actions. A suitable incentive plan does not preclude appropriately derived flexible prices for certain products or services where warranted

    Full Text Available This paper deals with the general problem of utilizing of renewable energy sources to generate electric energy. Recent advances in renewable energy power generation technologies, e.g., wind and photovoltaic (PV technologies, have led to increased interest in the application of these generation devices as distributed generation (DG units. This paper presents the results of an investigation into possible improvements in the system voltage profile and reduction of system losses when adding wind power DG (wind-DG to a distribution system. Simulation results are given for a case study, and these show that properly sized wind DGs, placed at carefully selected sites near key distribution substations, could be very effective in improving the distribution system voltage profile and reducing power losses, and hence could  improve the effective capacity of the system.

    Experience gained with available solar thermal technologies enlighten on options for research and development on solar electricity generation. The proposed analysis of new solar technologies concerns market, costs and profit viewpoint: - Systems under development have to fit with consumers' needs and utilities' specifications, technology is not the only item to study. - Expense headings depend on technological options and operation procedures such as size of the plant, solar only or hybrid concept. - Anticipation of revenues highly depends on direct insolation quality and on local conditions for introducing the electric power generated into the network: daily direct insolation measurements and annual local load curve are prerequisite data. Strategic advantages regarding environment and sustainable development are to be pointed out, specially in industrialized countries or for projects including financing institutions. As far as generating electric power on the grid is a major challenge in the development of a number of countries in the sun belt, cooperation between industrialized and developing countries, under the auspices of international organization, has to be promoted.

    Grid connections of large power generating units normally require more detailed studies compared to small single units. The required R and D-level depends on the specific characteristics of the production units and the connecting grid. An inquiry for a grid connection will raise questions for the grid owner regarding transmission capability, losses, fault currents, relay protection, dynamic stability etc. Then only a few larger wind farms have been built, the experiences from these types of grid connections are limited and for that reason it can be difficult to identify issues appropriate for further studies. To ensure that electric power generating units do not have unacceptable impact on the grid, directions from the Swedish TSO (Svenska Kraftnaet) have been stated. The directions deal, for example, with power generation in specific ranges of voltage level and frequency and the possibility to remain connected to the grid when different faults occur. The requirements and the consequences of these directions are illustrated. There are three main issues that should be considered: Influence on the power flow from generating units regarding voltage level, currents, losses etc.; Different types of electric systems in generating units contribute to different levels of fault currents. For that reason the resulting fault current levels have to be studied; It is required that generating units should remain connected to the grid at different modes of operation and faults. These modes have to be verified. Load flow and dynamic studies normally demand computer models. Comprehensive models, for instance of wind farms, can bee difficult to design and normally large computer capacity is required. Therefore simplified methods to perform relevant studies are described. How to model an electric power generating unit regarding fault currents and dynamic stability is described. An inquiry for a grid connection normally brings about a discussion concerning administration. To make it

    2015-07-01

    The investigations of cracks growth in the fractured turbine rotors point out at theirs fatigue nature. The main reason of turbine shafts fatigue damage is theirs periodical startups which are typical for steam turbines. Each startup of a turbine is accompanied by the connection of turbine generator to electrical network. During the connection because of the phase shift between the vector of electromotive force of turbine generator and the vector of supply-line voltage the short-term but powerful reactive shaft torque arises. This torque causes torsional vibrations and fatigue damage of turbine shafts of different intensity. Based on the 3D finite element model of turbine shaft of the steam turbine K-200-130 and the mechanical properties of rotor steel there was estimated the fatigue damage of the shaft at its torsional vibrations arising as a result of connection of turbine generator to electric network.

    Hayashi, Yasuhiro; Matsuki, Junya; Hanai, Yuji; Hosokawa, Shinpei; Kobayashi, Naoki

    Recently, the total number of distributed generation such as photovoltaic generation system and wind turbine generation system connected to distribution network is drastically increased. Distributed generation utilizing renewable energy can reduce the distribution loss and emission of CO2. However the distribution network with the distributed generators must be operated keeping reliability of power supply and power quality. In this paper, the authors propose a computation method to determine the maximum output of a distributed generator under the operational constrains ((1) voltage limit, (2) line current capacity, and (3) no reverse flow to bank) at arbitrary connection point and hourly period. In the proposed method, three-phase iterative load flow calculation is applied to evaluate the above operational constraints. Three-phase iterative load flow calculation has two simple procedures: (Procedure1) addition of load currents from terminal node of feeder to root one, and (Procedure2) subtraction of voltage drop from root node of feeder to terminal one. In order to check the validity of the proposed method, numerical simulations are accomplished for a distribution system model. Furthermore, characteristics of locational and hourly maximum output of distributed generator connected to distribution feeder are analyzed by several numerical examples.

    A common collector is formed, connecting all the branch routes fitted with check flap valves and controllable valves and attached to the blowdown routes of each steam generator. The common collector is attached to the inlet of the safety valve system. The outlet of this safety valve system is connected via a connecting branch to the outlet of the pressurizer safety valve system. The outlets of the pressurizer safety valves open to the pressurizer relief tank. The whole is accommodated in the containment, which ensures that no radioactivity leaks into air during a steam generator accidents. The outlets of the separately controlled safety valves at the attachment branches as well as of the safety valve system of the common collector, reach below the water level of the tank; water is thus cooled at the saturation limit whereby formation of steam by expansion inside the containment is prevented.

  16. Change in network connectivity during fictive-gasping generation in hypoxia: Prevention by a metabolic intermediate

    Directory of Open Access Journals (Sweden)

    Andrés eNieto-Posadas

    2014-07-01

    Full Text Available The neuronal circuit in charge of generating the respiratory rhythms, localized in the pre-Bötzinger complex (preBötC, is configured to produce fictive-eupnea during normoxia and reconfigures to produce fictive-gasping during hypoxic conditions in vitro. The mechanisms involved in such reconfiguration have been extensively investigated by cell-focused studies, but the actual changes at the network level remain elusive. Since a failure to generate gasping has been linked to Sudden Infant Death Syndrome, the study of gasping generation and pharmacological approaches to promote it may have clinical relevance. Here, we study the changes in network dynamics and circuit reconfiguration that occur during the transition to fictive-gasping generation in the brainstem slice preparation by recording the preBötC with multi-electrode arrays and assessing correlated firing among respiratory neurons or clusters of respiratory neurons (multiunits. We studied whether the respiratory network reconfiguration in hypoxia involves changes in either the number of active respiratory elements, the number of functional connections among elements, or the strength of these connections. Moreover, we tested the influence of isocitrate, a Krebs cycle intermediate that has recently been shown to promote breathing, on the configuration of the preBötC circuit during normoxia and on its reconfiguration during hypoxia. We found that, in contrast to previous suggestions based on cell-focused studies, the number and the overall activity of respiratory neurons change only slightly during hypoxia. However, hypoxia induces a reduction in the strength of functional connectivity within the circuit without reducing the number of connections. Isocitrate prevented this reduction during hypoxia while increasing the strength of network connectivity. In conclusion, we provide an overview of the configuration of the respiratory network under control conditions and how it is reconfigured

  17. Identification of Synchronous Generator Electric Parameters Connected to the Distribution Grid

    2017-04-01

    Full Text Available According to modern trends, the power grids with distributed generation will have an open system architecture. It means that active consumers, owners of distributed power units, including mobile units, must have free access to the grid, like when using internet, so it is necessary to have plug and play technologies. Thanks to them, the system will be able to identify the unit type and the unit parameters. Therefore, the main aim of research, described in the paper, was to develop and research a new method of electric parameters identification of synchronous generator. The main feature of the proposed method is that parameter identification is performed while the generator to the grid, so it fits in the technological process of operation of the machine and does not influence on the connection time of the machine. For the implementation of the method, it is not necessary to create dangerous operation modes for the machine or to have additional expensive equipment and it can be used for salient pole machines and round rotor machines. The parameter identification accuracy can be achieved by more accurate account of electromechanical transient process, and making of overdetermined system with many more numbers of equations. Parameter identification will be made with each generator connection to the grid. Comparing data obtained from each connection, the middle values can be find by numerical method, and thus, each subsequent identification will accurate the machine parameters.

    2017-07-01

    Full Text Available There is direct correlation between building powerful destination brands and the degree to which tourists and locals share the brands values. The massive penetration of the active population by Generation Y has generated a major shift in tourism marketing, based on the profile of this cohort. The members of Generation Y are very different from previous generations. The so-called “digital natives” share high technological proficiency; they like to share their skills; they are disloyal consumers; and they are affected by trends. In order to connect with members of Generation Y and to actively involve them into the life of tourist destinations, viral, participative, interactive, networked and versatile marketing techniques should be employed. This article introduces the Intelligent Solution for Brand Culturalization (CUBIS Project, which is a collaborative research initiative that offers to Destination Management Organizations an innovative idea of how to connect the members of Generation Y with destination brands using information and communication technologies (ICT. The CUBIS Project aims to create emotional attachment with the brand values and supports the adoption of the brand by young locals and tourists. The CUBIS idea is flexible and highly adaptable to other destinations. The article uses exploratory qualitative research in the form of a case study.

    In this paper it is considered the use of Distributed Generation (GD) as a further option to centralized generation of electricity and treats its photovoltaic systems connected to power network (SFCR's) technology as an option in this interesting 'new' model to plan the expansion of the brazilian electrical energy matrix, mainly in urban centres. For this reason, it was necessary to mention the main characteristics of this technology as distributed generators, and the profile of his generation when connected in homes and commercial buildings. Moreover, it presents the benefits that these systems can offer the electricity sector, society and the economy. In the study of Photovoltaic Power Systems Programme (PVPS), specifically the situation of this technology in Germany, realized that the creation of mechanisms of financial incentives provided to implement some of the main barriers associated with the integration of photovoltaic systems as distributed generators. In assessing the Brazilian context, there was the incipient photovoltaic market in the country, even taking some systems already installed, note that the vast majority are intended for studies of Research and Development. There is also the exploitation of photovoltaic systems connected to the network for use in homes, businesses or industries, probably because of the lack of incentive programs for SFCR's. Although there is a programme of incentives to Alternative Sources of Electricity - Proinfa, it does not consider the SFCR's in its guidelines for qualification, only the wind systems, small hydroelectric plants and systems powered by biomass. Point is, therefore, the need for the creation of an energy policy that encourages the Brazilian market photovoltaic, more precisely a policy of offering incentives conditions of maturity of this technology when connected to the network - technical standards, decrease costs, creation of hand of specialized work, installation of manufacturers

    Microgrid research and development in the past decades have been one of the most popular topics. Similarly, the photovoltaic generation has been surging among renewable generation in the past few years, thanks to the availability, affordability, technology maturity of the PV panels and the PV inverter in the general market. Unfortunately, quite often, the PV installations are connected to weak grids and may have been considered as the culprit of poor power quality affecting other loads in particular sensitive loads connected to the same point of common coupling (PCC). This paper is intended to demystify the renewable generation, and turns the negative perception into positive revelation of the superiority of PV generation to the power quality improvement in a microgrid system. The main objective of this work is to develop a control method for the PV inverter so that the power quality at the PCC will be improved under various disturbances. The method is to control the reactive current based on utilizing the grid current to counteract the negative impact of the disturbances. The proposed control method is verified in PSIM platform. Promising results have been obtained.

  4. Dynamic analysis of combined photovoltaic source and synchronous generator connected to power grid

    Mahabal, Divya

    In the world of expanding economy and technology, the energy demand is likely to increase even with the global efforts of saving and increasing energy efficiency. Higher oil prices, effects of greenhouse gases, and concerns over other environmental impacts gave way to Distributed Generation (DG). With adequate awareness and support, DG's can meet these rising energy demands at lower prices compared to conventional methods. Extensive research is taking place in different areas like fuel cells, photovoltaic cells, wind turbines, and gas turbines. DG's when connected to a grid increase the overall efficiency of the power grid. It is believed that three-fifth of the world's electricity would account for renewable energy by middle of 21st century. This thesis presents the dynamic analysis of a grid connected photovoltaic (PV) system and synchronous generator. A grid is considered as an infinite bus. The photovol-taic system and synchronous generator act as small scale distributed energy resources. The output of the photovoltaic system depends on the light intensity, temperature, and irradiance levels of sun. The maximum power point tracking and DC/AC converter are also modeled for the photovoltaic system. The PV system is connected to the grid through DC/AC system. Different combinations of PV and synchronous generator are modeled with the grid to study the dynamics of the proposed system. The dynamics of the test system is analyzed by subjecting the system to several disturbances under various conditions. All modules are individually modeled and con-nected using MATLAB/Simulink software package. Results from the study show that, as the penetration of renewable energy sources like PV increases into the power system, the dynamics of the system becomes faster. When considering cases such as load switching, PV cannot deliver more power as the performance of PV depends on environmental conditions. Synchronous generator in power system can produce the required amount of

This paper presents a visual optimization approach in which the planner plays an important role in determining the optimal siting and sizing of the DG through the choice of the appropriate weight factors of the parameters included in the optimization technique according to the system deficiencies. Losses, voltage profile and short circuit level are used in the algorithm to determine the optimum sizes and locations of the DG. The short circuit level parameter is introduced to represent the protective device requirements in the selection of the size and location of the DG. The proposed technique has been tested on the IEEE 24 - bus mesh connected test system. The obtained results showed clearly that the optimal size and location can be simply determined through the proposed approach. (author)

  7. Modified Grid-Connected CSI for Hybrid PV/Wind Power Generation System

    Full Text Available The principle of a power conditioning unit for hybrid PV/wind power generation system is proposed. The proposed power conditioner is based on the current source inverter (CSI topology. All energy sources are connected in parallel with a DC-bus through the modified wave-shaping circuits. To achieve the unity power factor at the utility grid, the DC-link current can be controlled via the wave-shaping circuits with the sinusoidal PWM scheme. In this work, the carrier-based PWM scheme is also proposed to minimize the utility current THD. The power rating of the proposed system can be increased by connecting more PV/wind modules through their wave-shaping circuits in parallel with the other modules. The details of the operating principles, the system configurations, and the design considerations are described. The effectiveness of the proposed CSI is demonstrated by simulation results.

    Full Text Available In the context of grid connected photovoitaic (PV generation systems, there are two paramount aspects regarding the Maximum Power Point Tracking (MPPT of the photovoltaic units and the continuity of the service. The most diffused MPPT algorithms are based on either perturb and observe, or on an incremental conductance approach and need both PV current and voltage measurements. Several topology reconfigurable converters are also associated with the PV plants, guaranteeing fault-tolerant features. The generation continuity can also be assured by interleaved inverters, which keep the system operating at reduced maximum power in case of failure. In this paper, an evolution of a hysteresis based MPPT algorithm is presented, based on the measurement of only one voltage, together with a novel space vector modulation suitable for a two-channel three-phase grid connected interleaved inverter. The proposed MMPT algorithm and modulation technique are tested by means of several numerical analyses on a PV generation system of about 200 kW maximum power. The results testify the validity of the proposed strategies, showing good performance, even during a fault occurrence and in the presence of deep shading conditions.

  10. Artificial Bee Colony Algorithm for Transient Performance Augmentation of Grid Connected Distributed Generation

    Chatterjee, A.; Ghoshal, S. P.; Mukherjee, V.

    In this paper, a conventional thermal power system equipped with automatic voltage regulator, IEEE type dual input power system stabilizer (PSS) PSS3B and integral controlled automatic generation control loop is considered. A distributed generation (DG) system consisting of aqua electrolyzer, photovoltaic cells, diesel engine generator, and some other energy storage devices like flywheel energy storage system and battery energy storage system is modeled. This hybrid distributed system is connected to the grid. While integrating this DG with the onventional thermal power system, improved transient performance is noticed. Further improvement in the transient performance of this grid connected DG is observed with the usage of superconducting magnetic energy storage device. The different tunable parameters of the proposed hybrid power system model are optimized by artificial bee colony (ABC) algorithm. The optimal solutions offered by the ABC algorithm are compared with those offered by genetic algorithm (GA). It is also revealed that the optimizing performance of the ABC is better than the GA for this specific application.

    The Connected Traveler framework seeks to boost the energy efficiency of personal travel and the overall transportation system by maximizing the accuracy of predicted traveler behavior in response to real-time feedback and incentives. It is anticipated that this approach will establish a feedback loop that 'learns' traveler preferences and customizes incentives to meet or exceed energy efficiency targets by empowering individual travelers with information needed to make energy-efficient choices and reducing the complexity required to validate transportation system energy savings. This handout provides an overview of NREL's Connected Traveler project, including graphics, milestones, and contact information.

  13. Models for the transient stability of conventional power generating stations connected to low inertia systems

    An ever-increasing requirement to integrate greater amounts of electrical energy from renewable sources especially from wind turbines and solar photo-voltaic installations exists and recent experience in the island of Ireland demonstrates that this requirement influences the behaviour of conventional generating stations. One observation is the change in the electrical power output of synchronous generators following a transient disturbance especially their oscillatory behaviour accompanied by similar oscillatory behaviour of the grid frequency, both becoming more pronounced with reducing grid inertia. This behaviour cannot be reproduced with existing mathematical models indicating that an understanding of the behaviour of synchronous generators, subjected to various disturbances especially in a system with low inertia requires a new modelling technique. Thus two models of a generating station based on a double pendulum described by a system of coupled nonlinear differential equations and suitable for analysis of its stability corresponding to infinite or finite grid inertia are presented. Formal analytic solutions of the equations of motion are given and compared with numerical solutions. In particular the new finite grid model will allow one to identify limitations to the operational range of the synchronous generators used in conventional power generation and also to identify limits, such as the allowable Rate of Change of Frequency which is currently set to ± 0.5 Hz/s and is a major factor in describing the volatility of a grid as well as identifying requirements to the total inertia necessary, which is currently provided by conventional power generators only, thus allowing one to maximise the usage of grid connected non-synchronous generators, e.g., wind turbines and solar photo-voltaic installations.

  14. A Determination Method of the Restoration Configuration Considering Many Connections of Distributed Generators

    Takano, Hirotaka; Hayashi, Yasuhiro; Matsuki, Junya; Sugaya, Shuhei

    In the field of electrical power system, various approaches, such as utilization of renewable energy, loss reduction, and so on, have been taken to reduce CO2 emission. So as to work toward this goal, the total number of distributed generators (DGs) using renewable energy connected into 6.6kV distribution system has been increasing rapidly. However, when a fault occurs such as distribution line faults and bank faults, DGs connecting outage sections are disconnected simultaneously. Since the output of DGs influences feeder current and node voltage of distribution system, it is necessary to determine the optimal system configuration considering simultaneous disconnection and reconnection of DGs. In this paper, the authors propose a computation method to determine the optimal restoration configuration considering many connections of DGs. The feature of determined restoration configurations is prevention of the violation of operational constraints by disconnection and reconnection of DGs. Numerical simulations are carried out for a real scale distribution system model with 4 distribution substations, 72 distribution feeders, 252 sectionalizing switches (configuration candidates are 2252) and 23.2MW DGs (which is 14% of total load) in order to examine the validity of the proposed algorithm.

    Within most system analysis programs generators and motors are represented by an equivalent circuit model either a 2-axis model for both stators and rotor or a three-phase model of the stator and a two-axis model of the rotor. This may be adequate under certain operating conditions such as steady-state or some symmetrical faults but for inverter-fed motors or generators feeding into a rectified load a more rigorous model of the machine is required. This paper describes the theory and development of such a model, its integration with the power electronics and application to 6-pulse and 12-pulse converters, the latter being appropriate in systems similar to HVDC unit connection.

    The EU member states have to ensure to the producers of 'green' electricity guaranteed access to the electrical grid including for small installations - Directive (2001/77/EC) of EC. For this reason the European Commission (EC) supports the project 'Production of Electricity with RES and CHP for Homeowners' - PERCH, in the framework of the program 'Intelligent Energy - Europe'. In the report the issues of connection (technical, contractual, tariff and metering) are investigated for small installations using RES and micro CHP, which are owned by individual family houses, small enterprises, etc. It is pointed out that small installations, mainly PV-systems, wind generators and small CHP, as well as combination of these technologies are rapidly applied on the European market. In Bulgaria the application of small PV-systems and wind generators, as well as CHP at present is limited. The elements for encouragement of such systems are defined, as well as the barriers for their wider application. (author)

    The mode of payment creates powerful incentives affecting provider behavior and the efficiency, equity and quality outcomes of health finance reforms. This article examines provider incentives as well as administrative costs, and institutional conditions for successful implementation associated with provider payment alternatives. The alternatives considered are budget reforms, capitation, fee-for-service, and case-based reimbursement. We conclude that competition, whether through a regulated private sector or within a public system, has the potential to improve the performance of any payment method. All methods generate both adverse and beneficial incentives. Systems with mixed forms of provider payment can provide tradeoffs to offset the disadvantages of individual modes. Low-income countries should avoid complex payment systems requiring higher levels of institutional development.

    Malaysia is located almost on the equator and is blessed with an abundance of sunlight almost all year round. So obviously, with the right planning and strategies that are coupled to the right technology and development in the market, the potential for photovoltaic system as an alternative source of power in this country looks promising and is constantly gaining ground and popularity. Sunlight is free and the photovoltaic system is also emission and pollution free which is a guest boost to the current worldwide effort to reduce the global environmental problems. Utility giant Tenaga Nasional Berhad is in line with the Government aspiration to promote the development of solar photovoltaic in the country, who believe in the success and acceptance potential of the photovoltaic system as an alternative source of power generation for long term energy option. In March 1998, a contract was awarded by Tenaga Nasional Berhad to its research subsidiary, Tenaga Nasional Research and Development Sdn. Bhd. to undertake a pilot research project on the development of a grid connected photovoltaic system. This research project is co-funded by the Electric Supply Industry Trust fund. One of the main objective of this research project is to seek the best approach to popularize the Grid Connected Photovoltaic System for domestic as well as suitable commercial premises in this country. This paper will report the initial findings of the project in terms of technical capability and commercial liability. (Author)

    Australia is heavily dependent on coal for electricity generation. The Renewable Energy Target has spurred growth in the utilization of renewable energy sources, with further growth expected into the future. Australia's strongest renewable energy sources are generally distant from the transmission network in resource ‘basins’. Investment is needed to augment the transmission network to enable delivery of electricity from these sources to consumers. Considerable economies of scale flow from anticipating the connection of numerous generators in an area over time and sizing augmentations accordingly. Following a lengthy rulemaking process, the National Electricity Rules were recently amended by a new rule, designed to facilitate the construction of such efficiently sized augmentations. However, the new rule is more conservative than initially envisaged, making little substantive change to the current frameworks for augmentation and connection. This paper outlines these frameworks and the rulemaking process and identifies the key debates surrounding the rule change are identified. This paper then provides a detailed analysis of the new rule, concluding that it is defective in a number of respects and is unlikely to result in the efficient and timely augmentation of the network needed to unlock the potential of Australia's strongest renewable energy resources. - Highlights: ► Remoteness of renewable energy sources is a barrier to greater renewable energy utilization. ► Significant economies of scale flow from efficiently-sized transmission network augmentation. ► Current frameworks in Australia do not incentivise efficiently-sized network augmentations. ► The lack of property rights in an augmentation is particularly problematic. ► The new Scale Efficient Network Extensions rule is not apt to facilitate efficiently-sized network augmentations.

    This paper analyses the relation between authority and incentives. It extends the standard principal--agent model by a project selection stage in which the principal can either delegate the choice of project to the agent or keep the authority. The agent's subsequent choice of effort depends both on monetary incentives and the selected project. We find that the consideration of effort incentives makes the principal less likely to delegate the authority over projects to the agent. In fact, if t...

    Incentive drilling contracts historically have been based on the footage and turnkey concepts. Because these concepts have not been used widely in the international and offshore arenas, this paper discusses other innovative approaches to incentive contracts. Case studies of recently completed or current international and offshore contracts are presented to describe incentive projects based on a performance bonus (Case 1), lump sum per well (Case 2), target time and cap for a specified hole section (Case 3), and per-well target time (Case 4). This paper concludes with a review and comparison of the case studies and a general discussion of factors that produce successful innovative incentive programs that enhance drilling efficiency

  6. Voltage Control Scheme with Distributed Generation and Grid Connected Converter in a DC Microgrid

    2014-10-01

    Full Text Available Direct Current (DC microgrids are expected to become larger due to the rapid growth of DC energy sources and power loads. As the scale of the system expends, the importance of voltage control will be increased to operate power systems stably. Many studies have been performed on voltage control methods in a DC microgrid, but most of them focused only on a small scale microgrid, such as a building microgrid. Therefore, a new control method is needed for a middle or large scale DC microgrid. This paper analyzes voltage drop problems in a large DC microgrid and proposes a cooperative voltage control scheme with a distributed generator (DG and a grid connected converter (GCC. For the voltage control with DGs, their location and capacity should be considered for economic operation in the systems. Accordingly, an optimal DG allocation algorithm is proposed to minimize the capacity of a DG for voltage control in DC microgrids. The proposed methods are verified with typical load types by a simulation using MATLAB and PSCAD/EMTDC.

    In this paper, the potential of utilizing wind and solar Private Distributed Generation (PDG) for utility interactive systems is investigated for 11 selected stations (sites) in Jordan. Six customer categories are considered: residential, office, commercial mall, school, hospital and hotel. The main goal of this study was to evaluate the potential of utilizing different grid connected PDG under different conditions such as their location, size, served building category, number of people who share and own the equipment and system type whether wind, solar or hybrid based. It was found that solar systems are still not attractive for all location due to their associated high cost, while wind systems would vary widely depending on the customer category, location and the size of the equipment. Based on the Benefit to Cost ratio criterion, the most attractive sites for installing wind PDGS for residential communities are Ras Muneef, Mafraq, Aqaba, Irbid and H5, while it doesn't seem attractive at Amman,Shoubak, Ghor Essafi, Deir Alla, Maan and H4. On the other hand, the wind on-grid PDGS is very attractive at Ras Muneef, mafraq and Aqaba for commercial buildings, less attractive at H5 and irbid, while it's not attractive at the other sites. The attraction for hybrid PDG systems is closer to those of wind systems alone. (authors).

    This paper studies the effects of peer pressure on incentives. We assume that, in addition to the material payoff, each agent's utility includes the psychological payoff from peer pressure generated by a comparison of effort costs. We show that the optimal incentive schemes depend mainly on the degree of peer pressure and of the heterogeneity of agents. Furthermore, we examine the optimal organizational forms in terms of the principal''s intention to make use of the effects of peer pressure.

  10. Effect of wind generation system types on Micro-Grid (MG) fault performance during both standalone and grid connected modes

    Kamel, Rashad M.

    2014-01-01

    Highlights: • This paper evaluated the effects of different wind system types on fault performance of Micro-Grid. • Both standalone and grid connected modes are considered. • The MG earthing system configuration is taken in consideration. - Abstract: Recently, there are three wind generation (WG) system types. The first type is called Fixed Speed Wind Generation (FSWG) system, which employs squirrel cage induction generators. Double Fed Induction Generator (DFIG) is utilized in the second type. The third type is called Full Converter Wind Generation (FCWG) system, which is interfaced with Micro-Grid (MG) through a back to back converter. During fault occurrence, each WG has its performance and characteristics which are determined by the generator physical characteristics and the MG earthing system configuration. For some WG types, the fault current depends also on the control algorithm of the power converter. The main target of this paper is to investigate and estimate how the fault performance of MG during both standalone and grid-connected modes is influenced by the type of WG. It is found during standalone mode that the type of the employed WG has a dominant impact on the MG performance under fault disturbance. On the contrary, the type of the employed WG has a negligible effect on the MG fault performance during grid-connected mode. This is because the main grid contributes most of the fault current. Effects of earthing system type on MG performance are highlighted

    2012-01-15

    Over the past years, interest has grown in the potential for the renewable energy industry to create jobs. Governments are seeking win-win solutions to the dual challenge of high unemployment and climate change. By 2010, USD 51 billion had been pledged to renewables in stimulus packages, and by early 2011 there were 119 countries with some kind of policy target and/or support policy for renewable energy, such as feed-in tariffs, quota obligations, favourable tax treatment and public loans or grants, many of which explicitly target job creation as a policy goal. Policy-makers in many countries are now designing renewable energy policies that aim to create new jobs, build industries and benefit particular geographic areas. But how much do we know for certain about the job creation potential for renewable energy? This working paper aims to provide an overview of current knowledge on five questions: (1) How can jobs in renewable energy be characterised?; (2) How are they shared out across the technology value chain and what skill levels are required?; (3) How many jobs currently exist and where are they in the world?; (4) How many renewable energy jobs could there be in the future?; and (5) What policy frameworks can be used to promote employment benefits from renewable energy? This paper focuses on grid-connected electricity generation technologies and biofuels. Since the employment potential of off-grid applications is large, it will be covered by a forthcoming study by IRENA on job creation in the context of energy access, based on a number of case studies.

  13. Flapping foil power generator performance enhanced with a spring-connected tail

    Liu, Zhengliang; Tian, Fang-Bao; Young, John; Lai, Joseph C. S.

    2017-12-01

    The flexibility effects on the performance of a flapping foil power generator are numerically studied by using the immersed boundary-lattice Boltzmann method at a Reynolds number of 1100. The flapping foil system consists of a rigid NACA0015 foil undergoing harmonic pitch and plunge motions and a passively actuated flat plate pinned to the trailing edge of the rigid foil. The flexibility is modeled by a torsional spring model at the conjuncture of the rigid foil and the tail. Here, a parametric study on mass density and natural frequency is conducted under the optimum kinematic condition of the rigid system identified from the literature and numerical simulations made for reduced frequency f* = 0.04-0.24 and pitch amplitude θ0 = 40°-90°. Four typical cases are discussed in detail by considering time histories of hydrodynamic loads and tail deformations under the optimal and non-optimal kinematic conditions. Results show that under the rigid-system optimal kinematic condition, a tail with appropriate mass density (μ = 0.60) and resonant frequency ( fr*=1.18 ) can improve the maximum efficiency by 7.24% accompanied by an increase of 6.63% in power compared to those of a rigid foil with a rigid tail. This is because the deflection of the tail reduces the low pressure region on the pressure surface (i.e., the lower surface during the upstroke or the upper surface during the downstroke) caused by the leading edge vortex after the stroke reversal, resulting in a higher efficiency. At high flapping frequencies, a spring-connected tail ( fr*=0.13 ) eliminates the large spike in the moment observed in high stiffness cases, reducing the power required for the pitch motion, resulting in 117% improvement in efficiency over that with a rigid tail at a reduced frequency of 0.24.

  15. The Importance of Lateral Connections in the Parietal Cortex for Generating Motor Plans.

    Directory of Open Access Journals (Sweden)

    Derrik E Asher

    Full Text Available Substantial evidence has highlighted the significant role of associative brain areas, such as the posterior parietal cortex (PPC in transforming multimodal sensory information into motor plans. However, little is known about how different sensory information, which can have different delays or be absent, combines to produce a motor plan, such as executing a reaching movement. To address these issues, we constructed four biologically plausible network architectures to simulate PPC: 1 feedforward from sensory input to the PPC to a motor output area, 2 feedforward with the addition of an efference copy from the motor area, 3 feedforward with the addition of lateral or recurrent connectivity across PPC neurons, and 4 feedforward plus efference copy, and lateral connections. Using an evolutionary strategy, the connectivity of these network architectures was evolved to execute visually guided movements, where the target stimulus provided visual input for the entirety of each trial. The models were then tested on a memory guided motor task, where the visual target disappeared after a short duration. Sensory input to the neural networks had sensory delays consistent with results from monkey studies. We found that lateral connections within the PPC resulted in smoother movements and were necessary for accurate movements in the absence of visual input. The addition of lateral connections resulted in velocity profiles consistent with those observed in human and non-human primate visually guided studies of reaching, and allowed for smooth, rapid, and accurate movements under all conditions. In contrast, Feedforward or Feedback architectures were insufficient to overcome these challenges. Our results suggest that intrinsic lateral connections are critical for executing accurate, smooth motor plans.

    Full Text Available This paper studies the power electronic converters for grid connection of axial flux permanent magnetic synchronous generators (AFPMSG based variable speed wind turbine. In this paper, a new variable speed wind turbine with AFPMSG and Z-source inverter is proposed to improve number of switches and topology reliability. Besides, dynamic modeling of AFPMSG is presented to analyze grid connection of the proposed topology. The Z-source inverter controls maximum power point tracking (MPPT and delivering power to the grid. Therefore other DC–DC chopper is not required to control the rectified output voltage of generator in view of MPPT. As a result, the proposed topology requires less power electronic switches and the suggested system is more reliable against short circuit. The ability of proposed energy conversion system with AFPMSG is validated with simulation results and experimental results using PCI-1716 data acquisition system.

    CANDU is a relatively young technology which has demonstrated many achievements as an electrical power generation system. These achievements include an unsurpassed safety record, high annual and lifetime capacity factors, low electricity cost and a broad range of other performance strengths which together indicate that the CANDU technology is fundamentally sound. Known capabilities not yet fully exploited, such as advanced fuel cycle options, indicate that CANDU technology will continue to pay strong dividends on research, development and design investment. This provides a strong incentive for the improvement of CANDU on a continuing basis

    Shortages of rigs and personnel have encouraged discussion of designing incentive contracts in the drilling sector. However, for the drilling contracts, there are not a large variety of contract types in use. This article describes and analyses incentives for drilling contractors. These are directly represented by the compensation formats utilised in the present and in the consecutive drilling contracts. Indirectly, incentives are also provided by the evaluation criteria that oil companies use for awarding drilling assignments. Changes in contract format pose a number of relevant questions relating to resource management, and the article takes an in-depth look at some of these. Do evaluation criteria for awarding drilling assignments encourage the development of new technology and solutions? How will a stronger focus on drilling efficiency influence reservoir utilisation?

    2013-01-01

    If doctors take the costs of treatment into account when prescribing medication, their objectives differ from their patients' objectives because the patients are insured. This misalignment of interests hampers communication between patient and doctor. Giving cost incentives to doctors increases...... welfare if (i) the doctor's examination technology is sufficiently good or (ii) (marginal) costs of treatment are high enough. If the planner can costlessly choose the extent to which doctors take costs into account, he will opt for less than 100%.

    The generating function that gives rise to the orbifold Euler characteristic of the moduli space of punctured compact Riemann surfaces X(M s g ), g≥0 is derived explicitly. In the derivation, we show that we do not need to use the three-term recursion relation for the orthogonal polynomials. Also the continuum limit of Penner's connected generating function is considered and is shown to be formally equivalent to the free energy obtained recently by Distler and Vafa which exhibits the logarithmic divergences found for genus zero and one in D=1 matrix models. Finally, it is shown that the free energy and its s-derivatives are nothing but the continuum limit of a certain generating function introduced by Harer and Zagier in obtaining the true Euler characteristic with any number of punctures, e(Γ g s ), s≥0.

  8. Cited2 Regulates Neocortical Layer II/III Generation and Somatosensory Callosal Projection Neuron Development and Connectivity.

    The neocortex contains hundreds to thousands of distinct subtypes of precisely connected neurons, allowing it to perform remarkably complex tasks of high-level cognition. Callosal projection neurons (CPN) connect the cerebral hemispheres via the corpus callosum, integrating cortical information and playing key roles in associative cognition. CPN are a strikingly diverse set of neuronal subpopulations, and development of this diversity requires precise control by a complex, interactive set of molecular effectors. We have found that the transcriptional coregulator Cited2 regulates and refines two stages of CPN development. Cited2 is expressed broadly by progenitors in the embryonic day 15.5 subventricular zone, during the peak of superficial layer CPN birth, with a progressive postmitotic refinement in expression, becoming restricted to CPN of the somatosensory cortex postnatally. We generated progenitor-stage and postmitotic forebrain-specific Cited2 conditional knock-out mice, using the Emx1-Cre and NEX-Cre mouse lines, respectively. We demonstrate that Cited2 functions in progenitors, but is not necessary postmitotically, to regulate both (1) broad generation of layer II/III CPN and (2) acquisition of precise area-specific molecular identity and axonal/dendritic connectivity of somatosensory CPN. This novel CPN subtype-specific and area-specific control from progenitor action of Cited2 adds yet another layer of complexity to the multistage developmental regulation of neocortical development. This study identifies Cited2 as a novel subtype-specific and area-specific control over development of distinct subpopulations within the broad population of callosal projection neurons (CPN), whose axons connect the two cerebral hemispheres via the corpus callosum (CC). Currently, how the remarkable diversity of CPN subtypes is specified, and how they differentiate to form highly precise and specific circuits, are largely unknown. We found that Cited2 functions within

  11. A Current-Forced Line-Commutated Inverter for Single-Phase Grid-Connected Photovoltaic Generation Systems

    Directory of Open Access Journals (Sweden)

    UNLU, M.

    2015-05-01

    Full Text Available A simple power electronic interface based on the line-commutated inverter (LCI has been developed in order to inject sinusoidal current to the grid for single-phase grid-connected photovoltaic (PV energy generation systems. The proposed inverter facilitates controlling the injecting/grid current with a controllable power factor in contrast to the conventional LCI system. It is achieved that the total harmonic distortion (THD of the injecting currents for the different firing angles/power factors and reference currents is about 5% or less than 5%. Thus, the grid-connected standards for injecting current are satisfied without filter equipment unlike the conventional LCI system. The proposed system has been built in MATLAB/Simulink and examined experimentally on PV array of 160 W. The simulation and experimental results are better performance than the conventional line-commutated inverter methods reported in the literature. The proposed LCI has a simple and robust structure, and it can be easily synchronized with grid thanks to self-latching property of SCRs. Therefore, it is a good alternative for the power transferring from PV panels to the utility grid in grid-connected PV systems.

  12. A solar PV augmented hybrid scheme for enhanced wind power generation through improved control strategy for grid connected doubly fed induction generator

    Adikanda Parida

    2016-12-01

    Full Text Available In this paper, a wind power generation scheme using a grid connected doubly fed induction generator (DFIG augmented with solar PV has been proposed. A reactive power-based rotor speed and position estimation technique with reduced machine parameter sensitivity is also proposed to improve the performance of the DFIG controller. The estimation algorithm is based on model reference adaptive system (MRAS, which uses the air gap reactive power as the adjustable variable. The overall generation reliability of the wind energy conversion system can be considerably improved as both solar and wind energy can supplement each other during lean periods of either of the sources. The rotor-side DC-link voltage and active power generation at the stator terminals of the DFIG are maintained constant with minimum storage battery capacity using single converter arrangement without grid-side converter (GSC. The proposed scheme has been simulated and experimentally validated with a practical 2.5 kW DFIG using dSPACE CP1104 module which produced satisfactory results.

    Full Text Available In this article the notion ‘ecumenism’ is defined as a connecting movement of reconciling diversity, and the focus is on young people, referred to as ‘millennials’ living in the present-day global village. It addresses the youth’s interests or disinterests in the ‘institutionalised’ ecumenical movement. The following aspects are reflected upon: how ecumenism speaks to the youth; how ecumenism does not speak to the youth; and how to make ecumenism great again for the youth. It discusses young people’s perspectives on the world with regard to religion and tradition, sources of authority, issues of segregation and discrimination, ‘nomadic’ and a mentality which causes that one cannot expect them to stay in one church from baptism until death. The article reflects on the youth’s disposition to human realities concerning aspects such as the ecological crisis, global inequality, religious fundamentalism, violence and oppression, and the lack of a sense of belonging. The article concludes with some initiatives of the World Council of Churches to which young people can make a contribution.

  14. Differential Evolution Based IDWNN Controller for Fault Ride-Through of Grid-Connected Doubly Fed Induction Wind Generators.

    Manonmani, N; Subbiah, V; Sivakumar, L

    2015-01-01

    The key objective of wind turbine development is to ensure that output power is continuously increased. It is authenticated that wind turbines (WTs) supply the necessary reactive power to the grid at the time of fault and after fault to aid the flowing grid voltage. At this juncture, this paper introduces a novel heuristic based controller module employing differential evolution and neural network architecture to improve the low-voltage ride-through rate of grid-connected wind turbines, which are connected along with doubly fed induction generators (DFIGs). The traditional crowbar-based systems were basically applied to secure the rotor-side converter during the occurrence of grid faults. This traditional controller is found not to satisfy the desired requirement, since DFIG during the connection of crowbar acts like a squirrel cage module and absorbs the reactive power from the grid. This limitation is taken care of in this paper by introducing heuristic controllers that remove the usage of crowbar and ensure that wind turbines supply necessary reactive power to the grid during faults. The controller is designed in this paper to enhance the DFIG converter during the grid fault and this controller takes care of the ride-through fault without employing any other hardware modules. The paper introduces a double wavelet neural network controller which is appropriately tuned employing differential evolution. To validate the proposed controller module, a case study of wind farm with 1.5 MW wind turbines connected to a 25 kV distribution system exporting power to a 120 kV grid through a 30 km 25 kV feeder is carried out by simulation.

  17. Gas-to-power market and investment incentive for enhancing generation capacity: An analysis of Ghana's electricity sector

    Fritsch, Jorik; Poudineh, Rahmatallah

    2016-01-01

    Ghana's electricity generation capacity is currently insufficient to meet demand, making power outages and load shedding common. The resulting impact is potentially devastating for the country's growth prospects. Traditionally, lack of an affordable and reliable fuel supply for power generation, coupled with ineffective institutions and an unfavourable investment climate, have resulted in Ghana's electricity sector performing poorly. In light of the 2007 discovery of natural gas reserves in Ghanaian waters, this paper examines whether domestic gas could advance the performance of the electricity sector, and if so, how. The results of our analysis show that utilization of gas reserves in Ghana's gas-to-power market is an economically superior strategy compared to an export-oriented utilization scheme. The lack of an effective regulatory framework for investment, skill shortages, and an inefficient electricity pricing structure continue to be the main constraining factors. Our analysis also considers possible approaches to modification of the electricity tariff in order to send the right signal to potential investors in generation capacity, without compromising the affordability of power supply. - Highlights: •We examine if domestic gas can improve the Ghanaian electricity sector performance. •We compare domestic gas-to-power market utilisation versus gas export. •It shows that gas-to-power market is more economical compared to gas export. •Ineffective investment regime, skill shortage and inefficient tariffs are barriers.

  18. The political economy of grid-connected distributed power generation systems in California

    Science.gov (United States)

    Tongsopit, Sopitsuda

    For nearly two decades, distributed generation (DG) has been touted as a disruptive technology that could revolutionize the way electricity is produced and delivered. Whether this vision will be realized depends upon how this new technology, the existing technological system, i.e., the electric power grid, and the regulatory structure governing these systems co-evolve. My dissertation examines the interface between distributed generation and the electric power grid in California. Drawing upon published materials and interviews with members of the electric utility industry, I analyze technical, economic, and property rights conflicts between the two technological systems that together constitute what I hereby call the problem of interconnection. In attempting to understand the problem of interconnection, I seek answers to the following questions: (1) How and why are key decisions regarding interconnections made in California? (2) How do existing institutions adapt to the changing environment of more DG utilization? (3) To what extent are the DG-grid interactions shaped by technical, economic, and political factors? It is found that the California approach toward DG-grid interconnection is only one among many possible approaches and not necessarily the most technically or economically efficient. DG is integrated such that it becomes a passive extension to the centralized, hierarchical grid. This technical approach has been standardized while excluding possibilities that had historically seemed possible. The dissertation then poses the problem of interconnection in the context of evolving property rights to the U.S. power grid. California's distribution sector has been exposed to the same kinds of pressures that have diluted and diffused utilities' rights to generation and transmission control. But unlike the latter two sectors, the institutional recognition of distribution monopolies is still dominant. As a result, local distribution monopolies have been able to

    2006-01-01

    Portfolio theory indicates that risk management should take place at the group level. Hedging at the project level or in the individual business areas may lead to suboptimal results. However, the efficiency of a profit centre depends on its management's being able to influence factors that are crucial to the unit's financial results. Price hedging could be one such factor. In the wider perspective, this constitutes part of the balancing between centralisation and decentralisation. This article covers important elements of risk management and incentive design. It goes on to discuss the balancing of overall risk management at the group level and incentive design in profit centres and corporate units. Throughout the article, the oil industry serves as a case. (author)

    2015-04-06

    Untransposed transmission lines, unbalanced tap changer operations, and unbalanced loading in weak distribution lines can cause unbalanced-voltage conditions. The resulting unbalanced voltage at the point of interconnection affects proper gird integration and reduces the lifetime of wind turbines due to power oscillations, torque pulsations, mechanical stresses, energy losses, and uneven and overheating of the generator stator winding. This work investigates the dynamic impact of unbalanced voltage on the mechanical and electrical components of integrated Fatigue, Aerodynamics, Structures, and Turbulence (FAST) wind turbine generation systems (WTGs) of Type 1 (squirrel-cage induction generator) and Type 3 (doubly-fed induction generator). To alleviate this impact, a serially-connected compensator for a three-phase power line is proposed to balance the wind turbine-side voltage. Dynamic simulation studies are conducted in MATLAB/Simulink to compare the responses of these two types of wind turbine models under normal and unbalanced-voltage operation conditions and demonstrate the effectiveness of the proposed compensator.

    This paper analyses the relation between end-users energy attitudes and their corresponding energy behaviour. It presents empirical findings from analyses of the effects of two-way communication between consumers and power companies. Two-way communication has made available high quality data on energy consumption. In the build-up to the analysis in this paper the a number of aspects thought to influence energy consumption has been looked at; including standard of housing, number and age of residents, as well as socio-economic factors, behaviour and preferences. Here we choose to focus specifically on attitudes and behaviour. These aspects are controlled for price incentives. The combination of very tight peak power balance in the Nordic power system and few investments in extension of power networks has turned the focus towards manual or automatic demand-response which requires hourly metering for documentation. The data are two-fold: Hourly recordings of meter-data of electric consumption of 10,894 customers (nearly half of these had installed technology for remote load control) in two different network areas and survey-data from a questionnaire distributed to consumers that resulted in nearly 550 answers. During the winter 2003/2004 these customers were offered different price incentives. The analyses showed a net reduction in electricity consumption of 1,0 kWh/h at the most in peak load hours. The paper is based on two connected studies, 'End-user flexibility by efficient use of ICT' and 'Improving end-user knowledge for managing energy loads end consumption' conducted in Norway by the SINTEF group

However the main disadvantage of the NPC inverter is given by an unequal distribution of the losses in the semiconductor devices, which...... leads to an unequal distribution of temperature. By using the Active NPC topology, the power losses distribution problem is alleviated. The modulation strategy is a key issue for losses distribution in this topology. In this paper two known strategies are discussed and a new proposed PWM strategy......, namely the Adjustable Losses Distribution (ALD) PWM strategy is proposed for better losses distribution in the Active NPC (ANPC) topology. Simulations using Simulink and the PLECS toolbox have been done for evaluating efficiency of different NPC topologies and some experimental results are presented...

  7. Storage Dynamics and Non-Linear Connectivity between Landscape Units Control Runoff Generation and Stream Water Age Distributions

    2015-12-01

    We assess the influence of storage dynamics and non-linearities in hydrological connectivity on runoff generation and stream water ages, using a long-term record of daily isotopes in precipitation and stream flow. These were used to test a parsimonious tracer-aided runoff model for a Scottish catchment. The model tracks tracers and the ages of water fluxes through and between conceptual stores representing steeper hillslopes, dynamically saturated riparian peatlands and deeper groundwater (i.e. the main landscape units involved in runoff generation). Storage is largest in groundwater and on the steep hillslopes, though most dynamic mixing occurs in smaller stores in the riparian peat. The model also couples the ecohydrological effects of different vegetation communities in contrasting landscape units, by estimating evaporation, resulting moisture deficits and the ages of evaporated waters, which also affect the generation and age of runoff. Both stream flow and isotope variations are well-captured by the model, and the simulated storage and tracer dynamics in the main landscape units are consistent with independent measurements. The model predicts the mean age of runoff as ~1.8 years. On a daily basis, this varies from ~1 month in storm events, when younger waters draining the riparian peatland dominate, to around 4 years in dry periods, when groundwater sustains flow. Hydrological connectivity between the units varies non-linearly with storage which depends upon antecedent conditions and event characteristics. This, in turn, determines the spatial distribution of flow paths and the integration of their contrasting non-stationary ages. Improving the representation of storage dynamics and quantifying the ages of water fluxes in such models gives a more complete conceptualisation of the importance of the soil water fluxes in critical zone processes and a framework for tracking diffuse pollutants in water quality assessment.

    The new metal-organic framework materials, ZnF(Am 2 TAZ).solvents and ZnF(TAZ).solvents (Am 2 TAZ=3,5-diamino-1,2,4-triazole, TAZ=1,2,4-triazole), have been synthesized solvothermally and structurally characterized by either Rietveld refinement from powder XRD data or by single crystal X-ray diffraction. The three-dimensional structures of the compounds display open-ended, tubular channels, which are constituted of covalently bonded hexanuclear metallamacrocycles (Zn 6 F 6 (ligand) 6 ). The tubular channels are subsequently covalently joined into a honeycomb-like hexagonal array to generate the three-dimensional porous framework. In the case of ZnF(Am 2 TAZ).solvents, hydrophilic -NH 2 groups point into the channels, effectively reducing their inner diameter relative to ZnF(TAZ).solvents. The present compounds are isostructural to one another and to the previously reported ZnF(AmTAZ).solvents (AmTAZ=3-amino-1,2,4-triazole), illustrative of the fact that the internal size and chemical properties of the framework may be altered by modification of the small, heterocyclic ligand. In addition to demonstrating the ability to modify the basic framework, ZnF(TAZ).solvents and ZnF(Am 2 TAZ).solvents are two of the most thermally stable coordination frameworks known to date. - Graphical abstract: Top view of the open-ended, honeycomb tubular architecture of ZnF(Am 2 TAZ)

    Diesel generator (DG)-battery power systems are often adopted by telecom operators, especially in semi-urban and rural areas of developing countries. Unreliable electric grids (UEG), which have frequent and lengthy outages, are peculiar to these regions. DG-UEG-battery power system is an important kind of hybrid power system. System dispatch is one of the key factors to hybrid power system integration. In this paper, the system dispatch of a DG-UEG-lead acid battery power system is studied with the UEG of relatively ample electricity in Central African Republic (CAR) and UEG of poor electricity in Congo Republic (CR). The mathematical models of the power system and the UEG are studied for completing the system operation simulation program. The net present cost (NPC) of the power system is the main evaluation index. The state of charge (SOC) set points and battery bank charging current are the optimization variables. For the UEG in CAR, the optimal dispatch solution is SOC start and stop points 0.4 and 0.5 that belong to the Micro-Cycling strategy and charging current 0.1 C. For the UEG in CR, the optimal dispatch solution is of 0.1 and 0.8 that belongs to the Cycle-Charging strategy and 0.1 C. Charging current 0.1 C is suitable for both grid scenarios compared to 0.2 C. It makes the dispatch strategy design easier in commercial practices that there are a few very good candidate dispatch solutions with system NPC values close to that of the optimal solution for both UEG scenarios in CAR and CR.

    A novel two chamber up-flow microbial desalination cell (UMDC) was designed for evaluating desalination of real seawater with simultaneous wastewater treatment and energy generation. Two UMDCs were hydraulically connected in continuous flow mode (cascade mode) and operated at ten different hydraulic retention times (HRTs) [120 h to 12 h] and salt retention times (SRTs) [40 h to 4 h] for improved performance of chemical oxygen demand (COD) and salt removal. These UMDCs were operated at different combinations of high power (higher external resistance) and high current (low external resistance) mode to find the most suitable conditions for obtaining higher COD removal, salt removal, power production and current generation. The optimum HRT and SRT were 60 h and 40 h, respectively. The highest salt removal achieved was 72% at SRT of 40, while the highest COD removal was 83% at a HRT of 60 h. A maximum current density of 2.375 A/m 2 was obtained, while the maximum power density was 5.879 W/m 2 . The obtained results give an overlook for the scale up of UMDCs in the future. In the entire system, membrane fouling is still a major problem. As the operation time increases, this resulted in low power generation and low salt removal efficiency. The UMDCs can function as sustainable and alternative solution for real wastewater treatment and seawater desalination with resource recovery and power production.

    2014-01-01

    Results from experiments on a tap transformer based grid connection system for a variable speed vertical axis wind turbine are presented. The tap transformer based system topology consists of a passive diode rectifier, DC-link, IGBT inverter, LCL-filter, and tap transformer. Full range variable speed operation is enabled by using the different step-up ratios of a tap transformer. Simulations using MATLAB/Simulink have been performed in order to study the behavior of the system. A full experimental set up of the system has been used in the laboratory study, where a clone of the on-site generator was driven by an induction motor and the system was connected to a resistive load to better evaluate the performance. Furthermore, the system is run and evaluated for realistic wind speeds and variable speed operation. For a more complete picture of the system performance, a case study using real site Weibull parameters is done, comparing different tap selection options. The results show high system efficiency at nominal power and an increase in overall power output for full tap operation in comparison with the base case, a standard transformer. In addition, the loss distribution at different wind speeds is shown, which highlights the dominant losses at low and high wind speeds. Finally, means for further increasing the overall system efficiency are proposed.

    A classic left frontal-temporal brain network is known to support language processes. However, the level of participation of constituent regions, and the contribution of extra-canonical areas, is not fully understood; this is particularly true in children, and in individuals who have experienced early neurological insult. In the present work, we propose whole-brain connectivity and graph-theoretical analysis of magnetoencephalography (MEG) source estimates to provide robust maps of the pediatric expressive language network. We examined neuromagnetic data from a group of typically-developing young children ( n = 15, ages 4-6 years) and adolescents ( n = 14, 16-18 years) completing an auditory verb generation task in MEG. All source analyses were carried out using a linearly-constrained minimum-variance (LCMV) beamformer. Conventional differential analyses revealed significant ( p EVC) . Hub analysis revealed the importance of left perisylvian sites, i.e., Broca's and Wernicke's areas, across groups. The hemispheric distribution of frontal and temporal lobe EVC values was asymmetrical in most subjects; left dominant EVC was observed in 20% of young children, and 71% of adolescents. Interestingly, the adolescent group demonstrated increased critical sites in the right cerebellum, left inferior frontal gyrus (IFG) and left putamen. Here, we show that whole brain connectivity and network analysis can be used to map critical language sites in typical development; these methods may be useful for defining the margins of eloquent tissue in neurosurgical candidates.

  16. Dynamic imaging of coherent sources reveals different network connectivity underlying the generation and perpetuation of epileptic seizures.

    Directory of Open Access Journals (Sweden)

    Lydia Elshoff

    Full Text Available The concept of focal epilepsies includes a seizure origin in brain regions with hyper synchronous activity (epileptogenic zone and seizure onset zone and a complex epileptic network of different brain areas involved in the generation, propagation, and modulation of seizures. The purpose of this work was to study functional and effective connectivity between regions involved in networks of epileptic seizures. The beginning and middle part of focal seizures from ictal surface EEG data were analyzed using dynamic imaging of coherent sources (DICS, an inverse solution in the frequency domain which describes neuronal networks and coherences of oscillatory brain activities. The information flow (effective connectivity between coherent sources was investigated using the renormalized partial directed coherence (RPDC method. In 8/11 patients, the first and second source of epileptic activity as found by DICS were concordant with the operative resection site; these patients became seizure free after epilepsy surgery. In the remaining 3 patients, the results of DICS / RPDC calculations and the resection site were discordant; these patients had a poorer post-operative outcome. The first sources as found by DICS were located predominantly in cortical structures; subsequent sources included some subcortical structures: thalamus, Nucl. Subthalamicus and cerebellum. DICS seems to be a powerful tool to define the seizure onset zone and the epileptic networks involved. Seizure generation seems to be related to the propagation of epileptic activity from the primary source in the seizure onset zone, and maintenance of seizures is attributed to the perpetuation of epileptic activity between nodes in the epileptic network. Despite of these promising results, this proof of principle study needs further confirmation prior to the use of the described methods in the clinical praxis.

    Full Text Available Photovoltaic and wind are renewable energy resources that widely used and grow rapidly in fulfilling electricity demand. Powers from both technologies depend on sunlight intensity and wind speed. For small scale power generation, DC voltage from both technologies is low and requires step-up converter to raise DC voltage ratio before converted into AC voltage. To optimize this system, step-up converter must have high ratio and efficiency to a distance of wide voltage input. This paper proposed an operation simulation and arrangement of DC-DC converter along with DC-AC from hybrid source PV-Wind which integrated to grid utilities without using storage device. High Gain Integrated Cascade Boost (HGICB is DC-DC converter that has quadratic voltage ratio and used in this research. Then DC link connected to Voltage Source Inverter (VSI which interconnected with utility grid and controlled by current control method. The total installed capacity of hybrid source is 4.4 kW. Wind turbine uses PMSG along with full bridge rectifier. To maximize and stabilize the generated power, MPPT fuzzy is used. Result from the simulation shows that converter capable to maintain maximum power whether from PV and wind turbine which canalized to utility grid in various irradiation condition, wind speed, and grid load alteration.

    Material or financial incentives are widely used in an attempt to precipitate or reinforce behaviour change, including smoking cessation. They operate in workplaces, in clinics and hospitals, and to a lesser extent within community programmes. In this third update of our review we now include trials conducted in pregnant women, to reflect the increasing activity and resources now targeting this high-risk group of smokers. To determine whether incentives and contingency management programmes lead to higher long-term quit rates. We searched the Cochrane Tobacco Addiction Group Specialised Register, with additional searches of MEDLINE, EMBASE, CINAHL and PsycINFO. The most recent searches were in December 2014, although we also include two trials published in 2015. We considered randomised controlled trials, allocating individuals, workplaces, groups within workplaces, or communities to experimental or control conditions. We also considered controlled studies with baseline and post-intervention measures. We include studies in a mixed-population setting (e.g. community-, work-, institution-based), and also, for this update, trials in pregnant smokers. One author (KC) extracted data and a second (JH-B) checked them. We contacted study authors for additional data where necessary. The main outcome measure in the mixed-population studies was abstinence from smoking at longest follow-up, and at least six months from the start of the intervention. In the trials of pregnant smokers abstinence was measured at the longest follow-up, and at least to the end of the pregnancy. Twenty-one mixed-population studies met our inclusion criteria, covering more than 8400 participants. Ten studies were set in clinics or health centres, one in Thai villages served by community health workers, two in academic institutions, and the rest in worksites. All but six of the trials were run in the USA. The incentives included lottery tickets or prize draws, cash payments, vouchers for goods and

    Full Text Available Monte Carlo simulation using Simple Random Sampling (SRS technique is popularly known for its ability to handle complex uncertainty problems. However, to produce a reasonable result, it requires huge sample size. This makes it to be computationally expensive, time consuming and unfit for online power system applications. In this article, the performance of Latin Hypercube Sampling (LHS technique is explored and compared with SRS in term of accuracy, robustness and speed for small signal stability application in a wind generator-connected power system. The analysis is performed using probabilistic techniques via eigenvalue analysis on two standard networks (Single Machine Infinite Bus and IEEE 16–machine 68 bus test system. The accuracy of the two sampling techniques is determined by comparing their different sample sizes with the IDEAL (conventional. The robustness is determined based on a significant variance reduction when the experiment is repeated 100 times with different sample sizes using the two sampling techniques in turn. Some of the results show that sample sizes generated from LHS for small signal stability application produces the same result as that of the IDEAL values starting from 100 sample size. This shows that about 100 sample size of random variable generated using LHS method is good enough to produce reasonable results for practical purpose in small signal stability application. It is also revealed that LHS has the least variance when the experiment is repeated 100 times compared to SRS techniques. This signifies the robustness of LHS over that of SRS techniques. 100 sample size of LHS produces the same result as that of the conventional method consisting of 50000 sample size. The reduced sample size required by LHS gives it computational speed advantage (about six times over the conventional method.

As Renobell (2005 stated, image analysis encourages the development of critical capacity and contributes to developing a personal style for the gradual acquisition of a visual culture. Images educate and consequently, their presence in the field of education should not be a mere accompaniment to the text. They should not be limited to adorn or illustrate a linguistic content but to complement and deepen it, activating the thought and the reflection of the reader. In Internet culture, image as a focus of knowledge, of shared use, of social content and educational purposes, contribute to explain the implications and vivacity around this technological environment, which plays a leading role in the current social changes and movements. The culture of the network has changed our perceptual sensitivity to interpret images, which are now more complex, integrated, multidimensional and dynamic than ever. The interactivity, the strong relationship with the text content, the graphic sequentiality, the associated sound effects or the iconical text design reveal the importance of image in the net culture.

    The federal government offers a number of tax incentives to developers of biomass projects. This paper describes each tax benefit, explains what conditions must be met before the benefit is available, and offers practical insights gained from working for over 10 years in the field. Understanding what tax benefits are available is important because the more tax benefits a developer can qualify for in connection with his project, the less expensive the project will be to build and operate and the easier it will be to arrange financing because there will be higher returns in the project for potential investors

  6. Financial incentives and weight control.

    Jeffery, Robert W

    2012-11-01

    This paper reviews research studies evaluating the use of financial incentives to promote weight control conducted between 1972 and 2010. It provides an overview of behavioral theories pertaining to incentives and describes empirical studies evaluating specific aspects of incentives. Research on financial incentives and weight control has a history spanning more than 30 years. Early studies were guided by operant learning concepts from Psychology, while more recent studies have relied on economic theory. Both theoretical orientations argue that providing financial rewards for losing weight should motivate people to engage in behaviors that produce weight loss. Empirical research has strongly supported this idea. However, results vary widely due to differences in incentive size and schedule, as well as contextual factors. Thus, many important questions about the use of incentives have not yet been clearly answered. Weight-maintenance studies using financial incentives are particularly sparse, so that their long-term efficacy and thus, value in addressing the public health problem of obesity is unclear. Major obstacles to sustained applications of incentive in weight control are funding sources and acceptance by those who might benefit. Copyright © 2011 Elsevier Inc. All rights reserved.

    2017-02-01

    Stack connection (i.e., in series or parallel) of microbial fuel cell (MFC) is an efficient way to boost the power output for practical application. However, there is little information available on short-term changes in stack connection and its effect on the electricity generation and microbial community. In this study, a self-stacked submersible microbial fuel cell (SSMFC) powered by glycerol was tested to elucidate this important issue. In series connection, the maximum voltage output reached to 1.15 V, while maximum current density was 5.73 mA in parallel. In both connections, the maximum power density increased with the initial glycerol concentration. However, the glycerol degradation was even faster in parallel connection. When the SSMFC was shifted from series to parallel connection, the reactor reached to a stable power output without any lag phase. Meanwhile, the anodic microbial community compositions were nearly stable. Comparatively, after changing parallel to series connection, there was a lag period for the system to get stable again and the microbial community compositions became greatly different. This study is the first attempt to elucidate the influence of short-term changes in connection on the performance of MFC stack, and could provide insight to the practical utilization of MFC.

    This paper presents a modulated hysteresis direct torque control (MHDTC) applied to an induction generator (IG) used in wind energy conversion systems (WECs) connected to the electrical grid through a back-to-back converter. The principle of this strategy consists in superposing to the torque reference a triangular signal, as in the PWM strategy, with the desired switching frequency. This new modulated reference is compared to the estimated torque by using a hysteresis controller as in the classical direct torque control (DTC). The aim of this new approach is to lead to a constant frequency and low THD in grid current with a unit power factor and a minimum voltage variation despite the wind variation. To highlight the effectiveness of the proposed method, a comparison was made with classical DTC and field oriented control method (FOC). The obtained simulation results, with a variable wind profile, show an adequate dynamic of the conversion system using the proposed method compared to the classical approaches. Copyright © 2013 ISA.

    Although Brazil has great potential for photovoltaics (PV), and is particularly privileged by high solar radiation levels, the role of this renewable energy source (RES) at the Brazilian market is still very small, and the current legislation of the electric sector has no incentives for grid-connected PV systems. The high costs and the paradigm that this RES is feasible for grid-connection only for developed countries are the fundamental arguments placed to justify the lack of consideration of PV energy in Brazil. The main aim of this thesis is to develop a guideline to create a reliable legislation and regulation framework for the Brazilian electrical sector towards the implementation of a widespread grid-connected PV roofs program, and to show a grid parity analysis between conventional generation and PV generation. It also demonstrates the benefits of grid-connected PV systems and it presents the bottlenecks that limit the widespread adoption of PV energy at the Brazilian electrical sector mix. The proposed mechanism to be applied in Brazil is based on the German program (Feed-in Law) and it is analyzed under different scenarios. With this study, it is possible to make an economic viability analysis of grid-connected PV in Brazil, to identify the most suitable PV roof program size for the beginning of the program, and the consequent impacts on tariffs, through the dilution of these costs for the residential energy consumer. The grid-parity analysis shows that from 2015 and 2020 it will be possible to reach grid parity for PV in some regions in Brazil. It is possible that this parity happens even before that time, according to the interest rates applied in Brazil. In this context, it is crucial to create an incentive program to promote PV energy in Brazil, even if current prices are not competitive with conventional generation prices, so that the necessary experience to develop a large scale mechanism could happen with the maximum benefits and in an orderly way

    Tax expenditures-reductions in income tax liability resulting from a special tax provision-are often used to achieve economic and social objectives. The arguments for petroleum production tax incentives usually encompass some combination of enhancing energy security, rewarding risk, or generating additional investment in new technologies. Generally, however, some portion of any tax expenditure is spend on activities that would have occurred anyway. This paper is a review of tax incentives for petroleum production found two to be of questionable merit. Others, including tax preferences for enhanced oil recovery methods, which offered the potential for better returns on the tax dollar. Increased use of enhanced oil recovery techniques could lead to additional environmental costs, however, and these need to be factored into any cost-benefit calculation

    In a restructured power system, the monopoly generation utility is replaced by different electricity producers. There exists extreme price volatility caused by random failures by generation or/and transmission systems. In these cases, producers' profits can be much higher than those in the normal...... state. The reliability management of producers usually cannot be directly controlled by the system operators in a restructured power system.

    The kind of engagement industrial psychologists have shown can produce optimal performance relates more to a state of mind than to increasing participation in programs or motivating a workforce with financial incentives. In the context of quality improvement methodologies, the health promotion profession has yet to discover when, where and how large financial incentives should be and how they best fit in our processes. That is, there is no "standard work" for the use of extrinsic motivators. Yet, to argue against incentives given evidence to date has more to do with polemics than science.

    Douven, Rudy; McGuire, Thomas G; McWilliams, J Michael

    2015-01-01

    One goal of the Medicare Shared Savings Program for accountable care organizations (ACOs) is to reduce Medicare spending for ACOs' patients relative to the organizations' spending history. However, we found that current rules for setting ACO spending targets (or benchmarks) diminish ACOs' incentives to generate savings and may even encourage higher instead of lower Medicare spending. Spending in the three years before ACOs enter or renew a contract is weighted unequally in the benchmark calculation, with a high weight of 0.6 given to the year just before a new contract starts. Thus, ACOs have incentives to increase spending in that year to inflate their benchmark for future years and thereby make it easier to obtain shared savings from Medicare in the new contract period. We suggest strategies to improve incentives for ACOs, including changes to the weights used to determine benchmarks and new payment models that base an ACO's spending target not only on its own past performance but also on the performance of other ACOs or Medicare providers.

    International Nuclear Information System (INIS)

    Simsek, Hayal Ayca; Simsek, Nevzat

    2013-01-01

    Recently, the importance of renewable energy sources has increased significantly as climate change has become an important long term threat to global ecosystems and the world economy. In the face of increased concern about climate change and high fossil fuel costs together with a reduction in the primary energy sources such as oil, natural gas and coal, alternative energy sources (renewables) are increasingly needed to respond to the threat of climate change and growing energy demand in the world. Recent developments in Turkey, such as the liberalization of the electricity market and improvements in the renewable legislations, have accelerated the growth process and investment opportunities in the field of renewable energy. Turkey′s naturally endowed potential for renewables, such as solar, geothermal and wind, also accompanied these developments and attracted world attention to this market. In Turkey, renewable energy sources have gained great importance in the last decades due to growing energy demand and incentive policies which foster the utilization of renewable energy sources. This study aims to explore the availability and potential of renewable energy sources in Turkey and discuss the government policies and economic aspects. - highlights: • Turkey′s potential for renewable energy has attracted world attention. • Turkey has specific energy objectives in promoting renewable energy. • This paper evaluates recent incentives for renewable energy in Turkey. • Incentives in Turkey have led to more investment in renewable energy generation

When the current market is a monopoly, entry is considered as excessive if the social welfare under the post-entry Cournot-Nash equilibrium, net of entry coast, is lower than that under monopoly. However, this paper argues that, even if this is true, limiting entry is not an optimal choice of the benevolent government. The entrant has an incentive to produce more than ...

  1. Incentives to promote family planning.

    Science.gov (United States)

    Heil, Sarah H; Gaalema, Diann E; Herrmann, Evan S

    2012-11-01

    Over the past 60 years, population control has become an increasingly urgent issue worldwide as a growing population strains already limited resources. The use of financial incentives to promote family planning is an innovative approach that has potential to make a contribution to efforts to better manage population growth. This report reviews eight studies that examined the effect of incentives on family planning. Published studies that tested the impact of incentives to promote some aspect of family planning and included an appropriate control or comparison condition were reviewed. Incentives have been used to promote attendance at contraceptive education sessions, adoption and continuation of contraceptive methods, sterilization, and to limit family size. All but one of the eight studies reviewed reported positive outcomes, but weaknesses in study design and execution limit the strength of the conclusions that can be drawn. Review of this literature suggests that family planning behaviors, like other behaviors, are sensitive to incentives. Given the tremendous need for efficacious interventions in global efforts to manage population growth, further research on this topic using more rigorous experimental methods is warranted.

    2010-05-01

    The potential of fibre-optic connectivity based on micro-optical components for deployment at particular nodes of telecom access networks will be addressed. Low-cost micro-optic components which can be manufactured by high volume replication techniques can provide new functionalities or lead to optical performance improvements of permanent or demateable fibre connections. Some of the most interesting applications involving refractive micro lenses and new fibre alignment structures will be highlighted. Numerical simulations will be presented showing that expanded beam connectors are more robust to pollution than physical contact ferrule-based connectors. The advantages and drawbacks of expanded beam fibre coupling versus physical contact connectivity based on existing and micro-optical structures are discussed.

  3. Incentives for Energy Saving and Renewable Energy in the Netherlands

    2008-01-01

    Energy saving and renewable energy are again on the Dutch political agenda. Based on the governmental energy report, market parties have developed the action plan for the realisation of national renewable energy targets. The evaluation of recently closed subsidy programmes and development of new incentives take place in close cooperation among governmental organisations and market parties. For the financing of the action plan the government has reserved the budget up to 2011. The government believes that the implementation of energy efficiency and renewable energy will strengthen the national economy and that the benefits of these measures will exceed the costs. The main obstacles related to the implementation of a large scale wind power generation are: spatial integration, permits and connection to the grid. Also, the large scale biomass plants meet problems because of the lack of clear environmental and sustainability criteria. The Dutch targets for 2020 are: increasing of energy efficiency with 20%, 20% renewable energy and decreasing of CO 2 -emissions with 30%.(author)

    2012-01-01

    The master thesis “Spatial mapping of wind parks in Republic of Macedonia from aspect of power generation and connection to power grid” presents spatial aspects for setting of wind parks at favourable locations. The thesis presents a comprehensive analysis how to carry out the administrative procedures that are in force in Republic of Macedonia, a range of minimum allowed distances in setting of each of the wind plants within a wind parks, but also requirements for fulfilling the basic human rights in preserving quality of life of the people in rural areas where the wind parks are build. As a result, a compromise in setting of wind parks and a suitable solution of sustainable development should be reached. Therefore, the decision making process should be based on the following key factors: environmental, social and economic development of the area of concern. The production of wind power is strongly influenced by meteorological conditions and has an average factor of utilization of up to 30%. This low factor of utilization cannot be used for planning of the basic energy needs of the country, but it can contribute certainly towards the reduction of the participation of conventional power plants. Republic of Macedonia introduced feed-in tariffs as a subsiding mechanism for building and strong penetration of wind parks. Additional funding mechanisms include carbon financing and green-field credits, through development of projects in the framework of Clean Development Mechanism, which improves the economic feasibility of the project and increases the interest of the investors. The analysis of the relevant spatial aspects of setting wind parks in Republic of Macedonia based on balanced and sustainable spatial development is made with regards to the following thematic areas: exploiting the potential of wind energy, climate issues, geo morphological and geo seismically aspects, rational use of land, protection of agricultural land and forests, spatial allocation of

  14. Modeling regulated water utility investment incentives

    Padula, S.; Harou, J. J.

    2014-12-01

    This work attempts to model the infrastructure investment choices of privatized water utilities subject to rate of return and price cap regulation. The goal is to understand how regulation influences water companies' investment decisions such as their desire to engage in transfers with neighbouring companies. We formulate a profit maximization capacity expansion model that finds the schedule of new supply, demand management and transfer schemes that maintain the annual supply-demand balance and maximize a companies' profit under the 2010-15 price control process in England. Regulatory incentives for costs savings are also represented in the model. These include: the CIS scheme for the capital expenditure (capex) and incentive allowance schemes for the operating expenditure (opex) . The profit-maximizing investment program (what to build, when and what size) is compared with the least cost program (social optimum). We apply this formulation to several water companies in South East England to model performance and sensitivity to water network particulars. Results show that if companies' are able to outperform the regulatory assumption on the cost of capital, a capital bias can be generated, due to the fact that the capital expenditure, contrarily to opex, can be remunerated through the companies' regulatory capital value (RCV). The occurrence of the 'capital bias' or its entity depends on the extent to which a company can finance its investments at a rate below the allowed cost of capital. The bias can be reduced by the regulatory penalties for underperformances on the capital expenditure (CIS scheme); Sensitivity analysis can be applied by varying the CIS penalty to see how and to which extent this impacts the capital bias effect. We show how regulatory changes could potentially be devised to partially remove the 'capital bias' effect. Solutions potentially include allowing for incentives on total expenditure rather than separately for capex and opex and allowing

  15. Variation in Incentive Effects across Neighbourhoods

    Directory of Open Access Journals (Sweden)

    Mark J Hanly

    2014-03-01

    Full Text Available Small monetary incentives increase survey cooperation rates, however evidence suggests that the appeal of incentives may vary across sample subgroups. Fieldwork budgets can be most effectively distributed by targeting those subgroups where incentives will have the strongest appeal. We examine data from a randomised experiment implemented in the pilot phase of the Irish Longitudinal Study of Ageing, which randomly assigned households to receive a higher (€25 or lower (€10 incentive amount. Using a random effects logistic regression model, we observe a variable effect of the higher incentive across geographic neighbourhoods. The higher incentive has the largest impact in neighbourhoods where baseline cooperation is low, as predicted by Leverage-Saliency theory. Auxiliary neighbourhood-level variables are linked to the sample frame to explore this variation further, however none of these moderate the incentive effect, suggesting that richer information is needed to identify sample subgroups where incentive budgets should be directed.

  18. Federal tax incentives affecting coal and nuclear power economics

    International Nuclear Information System (INIS)

    Chapman, D.

    1982-01-01

    This paper analyzes the effect of federal corporate income tax incentives on coal and nuclear power developments. It estimates (1) the magnitudes of tax incentives in relationship to utility costs, (2) the relative magnitude of benefits going to coal and nuclear facilities, and (3) the influence which the time paths of tax payments and after-tax net income have upon possible incentives for premature construction and excess capacity. Utility planners currently believe that nuclear power enjoys an after-tax competitive advantage over coal plants. Investigation of investment-related credits, deductions, and exclusions in the Internal Revenue Code shows that nuclear power enjoys a more favorable tax subsidy because of its greater capital intensity. In the absence of tax subsidies, no utility would prefer nuclear power to coal generation. Tax changes now under consideration could increase the tax benefits to both without disturbing the differential advantage held by nuclear power. 43 references, 2 figures, 4 tables

  3. Investigation of existing financial incentive policies for solar photovoltaic systems in U.S. regions

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available This paper analyzes some of the existing incentives for solar photovoltaic (PV energy generation in the U.S. Four types of buildings (e.g., hospitals, large offices, large hotels, and secondary schools located in five different U.S. states, each having their own incentives, are selected and analyzed for the PV incentive policies. The payback period of the PV system is chosen as an indicator to analyze and critique the effectiveness of each incentive by comparing the payback periods before and after taking the incentive into consideration. Then a parametric analysis is conducted to determine the influence of the variation in key parameters, such as PV system capacity, capital cost of PV, sell back ratio and the performance-based incentive rate, on the performance of the PV system. The results show how the existing incentives can be effectively used to promote the PV systems in the U.S. and how variations of the parameters can impact the payback period of the PV systems. Through the evaluation of the existing incentive policies and the parametric study, this paper demonstrates that the type and level of incentives should be carefully determined in policy-making processes to effectively promote the PV systems.

    Nine PWA improved on the trained abstract words; seven PWA also showed generalization to concrete words in the same context-category. The region with the highest node degree in the trained abstract network across PWA was left inferior frontal gyrus pars triangularis (L IFGtri; while the highest node degree in the generalized concrete network was left precentral gyrus. Regions that showed increased connectivity for both training and generalization included L IFGtri, right middle frontal gyrus (MFG, and bilateral angular gyrus. Regions that showed increased connectivity regardless of whether or not treatment was given and whether or not treatment was successful included left MFG and bilateral superior frontal gyrus. Additionally, PWA who generalized showed more left than right hemisphere changes in both abstract and concrete networks; while PWA who improved on the trained abstract words, but did not generalize to concrete words showed more left than right hemisphere changes for the abstract network, but more right than left hemisphere changes for the concrete network. These results suggest that (a direct training and generalization are tapping into similar neural mechanisms, and (b changes in the left hemisphere coincide with better treatment outcomes.

    Full Text Available In regard to the rapid development of renewable energy sources, more and more photovoltaic (PV generation systems have been connected to main power networks, and it is critical to enhance their transient performance under short-circuit faults conditions. This paper proposes and studies the coordinated control of a flux-coupling-type superconducting fault current limiter (SFCL and a superconducting magnetic energy storage (SMES, to improve the fault ride through (FRT capability and smooth the power fluctuation of a grid-connected PV generation system. Theoretical analyses of the device structure, operating principle and control strategy are conducted, and a detailed simulation model of 100 kW class PV generation system is built in MATLAB/SIMULINK. During the simulations of the symmetrical and asymmetrical faults, the maximum power point tracking (MPPT control is disabled, and four different cases including without auxiliary, with SFCL, with SMES, and with SFCL-SMES, are compared. From the demonstrated results, the combination of without MPPT and with SFCL-SMES can more efficiently improve the point of common coupling (PCC voltage sag, inhibit the DC-link overvoltage and alleviate the power fluctuation. Finally, a preliminary parameter optimization method is suggested for the SFCL and the SMES, and it is helpful to promote their future application in the real PV projects.

    Incentives, i.e., either monetary or other benefits, can be used to reward couples for limiting their fertility; disincentives, or penalties, can be imposed for excessive fertility. Examples of the use of incentives or disincentives by the governments of India, Singapore, and Hawaii are cited. Direct cash payments or tax exemptions (timed variously) are the most common incentive used. The effectiveness and the morality of incentive/disincentive programs are discussed. It is felt that incentives should only be used after a social consensus has been reached and after family planning services have been made available to all groups in the society.

    Full Text Available This paper covers the question if and how incentive schemes work evaluated by their impact on company performance (market capitalization and profit before tax. Based on a unique data set for German executive directors of DAX companies it can be proved that neither short (STI nor long term incentives (LTI plans necessarily support the company success. It rather depends on the efficiency of each plan, i. e. on its design. Special attention has to be paid on target setting. Short term focused objectives often miss their targets, whereas long term oriented objectives significantly support the company success. To solve the prisoner’s dilemma between employers and employees by a quasi-endless game, additional measures may be helpful, such as share ownership guidelines.

    2014-01-01

    A global supervisory strategy for a micro-grid power generation system that comprises wind and photovoltaic generation subsystems, a flywheel storage system, and domestic loads connected both to the hybrid power generators and to the grid, is developed in this paper. The objectives of the supervisor control are, firstly, to satisfy in most cases the load power demand and, secondly, to check storage and grid constraints to prevent blackout, to reduce energy costs and greenhouse gas emissions, and to extend the life of the flywheel. For these purposes, the supervisor determines online the operation mode of the different generation subsystems, switching from maximum power conversion to power regulation. Decision criteria for the supervisor based on actual variables are presented. Finally, the performance of the supervisor is extensively assessed through computer simulation using a comprehensive nonlinear model of the studied system. - Highlights: • We supervise a micro-grid power generation system with an objective to produce clipping grid consumption. • The supervisor switch online from maximum power conversion to power regulation. • We provide services both for domestic users and for the distribution network manager. • The developed algorithm is tested and validated for different scenarios

Reports of outbreaks can prompt other countries to impose trade and travel restrictions, which has the potential to discourage reporting. However, reports can also bring medical assistance to contain the outbreak, including access to vaccines. We compiled data on reports of meningococcal meningitis to the World Health Organization (WHO) from 54 African countries between 1966 and 2002, a period is marked by two events: first, a large outbreak reported from many countries in 1987 associated with the Hajj that resulted in more stringent requirements for meningitis vaccination among pilgrims; and second, another large outbreak in Sub-Saharan Africa in 1996 that led to a new international mechanism to supply vaccines to countries reporting a meningitis outbreak. We used fixed-effects regression modeling to statistically estimate the effect of external forcing events on the number of countries reporting cases of meningitis to WHO. We find that the Hajj vaccination requirements started in 1988 were associated with reduced reporting, especially among countries with relatively fewer cases reported between 1966 and 1979. After the vaccine provision mechanism was in place in 1996, reporting among countries that had previously not reported meningitis outbreaks increased. These results indicate that countries may respond to changing incentives to report outbreaks when they can do so. In the long term, these incentives are likely to be more important than surveillance assistance in prompt reporting of outbreaks.

  17. Design of DC-DC Converter and its Control for a Wind Generation System Connected to an Isolated Load

    Full Text Available A method to design a Buck converter and its control, which are associated to a wind generation system that is feeding an isolated load, is presented in this paper. To design the converter a Thevenin equivalent is deduced, which represents the behavior of the wind turbine, the permanent magnet synchronous generator, and the rectifier. The design of the converter elements guarantees input/output voltages and inductor current ripples of 5 % or less. The output voltage control is developed with a proportional-integral-derivative controller and as design criteria a damping of 0,707 and cutoff frequency of 1/5 converter commutation frequency are selected. The designed controller regulates the output voltage faced load perturbations and wind speed variations.

    We proposed and experimentally demonstrated a novel radio-over-fiber architecture using an electrical mixer and an optical intensity modulator based on double side-band modulation scheme to generate dense wavelength-division multiplexing (DWDM) optical millimeter for carrying downstream data and centralized lightwave for carrying upstream data. Since the remaining optical carriers with high power have been reused, the optical power is effectively utilized; therefore the system cost can be reduced.

    We estimate and map the impacts that alternative national and subnational economic incentive structures for reducing emissions from deforestation (REDD+) in Indonesia would have had on greenhouse gas emissions and national and local revenue if they had been in place from 2000 to 2005. The impact of carbon payments on deforestation is calibrated econometrically from the pattern of observed deforestation and spatial variation in the benefits and costs of converting land to agriculture over that time period. We estimate that at an international carbon price of $10/tCO(2)e, a "mandatory incentive structure," such as a cap-and-trade or symmetric tax-and-subsidy program, would have reduced emissions by 163-247 MtCO(2)e/y (20-31% below the without-REDD+ reference scenario), while generating a programmatic budget surplus. In contrast, a "basic voluntary incentive structure" modeled after a standard payment-for-environmental-services program would have reduced emissions nationally by only 45-76 MtCO(2)e/y (6-9%), while generating a programmatic budget shortfall. By making four policy improvements--paying for net emission reductions at the scale of an entire district rather than site-by-site; paying for reductions relative to reference levels that match business-as-usual levels; sharing a portion of district-level revenues with the national government; and sharing a portion of the national government's responsibility for costs with districts--an "improved voluntary incentive structure" would have been nearly as effective as a mandatory incentive structure, reducing emissions by 136-207 MtCO(2)e/y (17-26%) and generating a programmatic budget surplus.

  1. The role of grid-connected, building-integrated photovoltaic generation in commercial building energy and power loads in a warm and sunny climate

    Braun, P.; Ruether, R.

    2010-01-01

    For large commercial buildings, power load delivery limits are contracted with the local electricity distribution utility, and are usually fixed at one or more levels over the year, according to the seasonal building loads, and depending on the specific country regulations. Especially in warm and sunny climates, solar electricity generation using building-integrated photovoltaics (BIPV) can assist in reducing commercial building loads, offering peak-shaving (power) benefits on top of the on-site generation of electricity (energy). This on-site power delivery capability gives these consumers the possibility of renegotiating demand contracts with their distribution utility. Commercial buildings that operate during daytime quite often have an energy consumption profile that is well matched by solar radiation availability, and depending on the building's available surface areas, BIPV can generate considerable portions of the energy requirements. In this work we present the role of grid-connected BIPV in reducing the load demands of a large and urban commercial building located in a warm climate in Brazil. The building and adjacent car parking lots can accommodate a 1 MWp BIPV generator, which closely matches the building's typical maximum power demands. Based on real solar radiation data and simultaneous building electricity demands for the year 2007, simulation of the annual solar generation profile of this on-site generator showed that the 1 MWp BIPV system could account for around 30% of the total building's energy consumption. In addition to the energy benefit, maximum power demands were reduced due to a good match between midday air-conditioning cooling loads and solar radiation availability on both a daily and seasonal basis. Furthermore, we have simulated the effect of this considerably large urban-sited generator on the local distribution network load, and have shown that the 1 MWp BIPV installation can also offer considerable benefits to the local utility in

  2. Using reporting requirements to improve employer wellness incentives and their regulation.

    2014-10-01

    Employer interest in offering financial incentives for healthy behaviors has been increasing. Some employers have begun to tie health plan-based rewards or penalties to standards involving tobacco use or biometric measures such as body mass index. The Patient Protection and Affordable Care Act attempts to strike a balance between the potential benefits and risks of wellness incentive programs by permitting these incentives but simultaneously limiting their use. Evidence about the implications of the newest generation of incentive programs for health, health costs, and burdens on individual employees will be critical for informing both private and public decision makers. After describing the many pieces of information that would be valuable for assessing these programs, this article proposes more narrowly targeted reporting requirements that could facilitate incentive program development, evaluation, and oversight.

    2014-01-01

    Full Text Available BIPV is now widely used in office and residential buildings, but its seismic performance still remained vague especially when the photovoltaic (PV modules are installed on high-rise building facades. A new form of reinforced concrete shear wall integrated with photovoltaic module is proposed in this paper, aiming to apply PV module to the facades of high-rise buildings. In this new form, the PV module is integrated with the reinforced concrete wall by U-shaped steel connectors through embedded steel plates. The lateral cyclic loading test is executed to investigate the seismic behavior and the electric and thermal performance with different drift angles. The seismic behavior, including failure pattern, lateral force-top displacement relationship, and deformation capacity, was investigated. The power generation and temperature variation on the back of the PV module and both sides of the shear wall were also tested. Two main results are demonstrated through the experiment: (1 the U-shaped steel connectors provide enough deformation capacity for the compatibility of the PV module to the shear wall during the whole cyclic test; (2 the electricity generation capacity is effective and stable during this seismic simulation test.

  4. An Adaptive Quadrature Signal Generation Based Single-Phase Phase-Locked Loop for Grid-Connected Applications

    2017-01-01

    The quadrature signal generation based phase-locked loops (QSG-PLLs) are highly popular for synchronization purposes in single-phase systems. The main difference among these PLLs often lies in the technique they use for creating the fictitious quadrature component. One of the easiest QSG approaches...... is delaying the original single-phase signal by a quarter of a cycle. The PLL with such QSG technique is often called the transfer delay based PLL (TD-PLL). The TD-PLL benefits from a simple structure, rather fast dynamic response, and a good detection accuracy when the grid frequency is at its nominal value......, but it suffers from a phase offset error and double frequency oscillatory error in the estimated phase and frequency in the presence of frequency drifts. In this paper, a simple yet effective approach to remove the aforementioned errors of the TD-PLL is proposed. The resultant PLL structure is called...

  5. Water Conservation and Economic Incentives

    Narayanan, M.

    2016-12-01

    Water has played a vital role in the progress of human civilization throughout history. Both agriculture based economics as well as industry based economics totally rely upon water for survival and prosperity. Water could be a limiting factor in dictating day-to-day human activities and as such one should learn to live within the limits of available natural resources. Most of the water on this earth is either salty or undrinkable. Only one percent of world's water is available for all the needs of human civilization. This includes human personal household needs, community activities, agriculture, industry, plant and animal life sustenance. The supply of usable fresh water is finite and the per capita consumption of fresh water needs to be reduced in particularly in some selected regions of this world. The United States consumes about 450 billion gallons of water every day. The U.S. daily average of water pumped by public water supply systems is 185 gallons per person. The biggest water gobbler in a household is the lawn. Typically, at least 50% of water consumed by households is used outdoors. Even inside a house, bathroom facilities claim nearly 75% of the water used. Here is a short list of economic Incentives that may help water conservation. (1) Providing rebates, refunds or other economic incentives to those consumers that are willing to change to modern technological methods. Examples include, but not limited to energy efficient washing machines, low-flush toilets and improved shower head designs. (2) Communities should provide economic incentives to limit the type and size of landscaping. (3) Need, necessity and nature of outdoor water use could be restricted whenever possible. (4) Sprinkler ban may be deemed appropriate in extreme cases. (5) Set up hotlines that can help penalize those that ignore water conservation guidelines. (6) Incorporating water conservation monitors. References: http://www.nrdc.org/water/http://www.ecy.wa.gov/programs/wr/ws/wtrcnsv.htmlhttp://www.sscwd.org/tips.html

  6. Induction of Heat Resistance in Wheat Coleoptiles by 4-Hydroxybenzoic Acid: Connection with the Generation of Reactive Oxygen Species

    Yastreb T.O.

    2012-08-01

    Full Text Available The effect of 4-hydroxybenzoic acid (4-HBA on resistance of coleoptiles of 4-day-old etiolated seedlings of wheat (Triticum aestivum L., cv. Elegiya to damaging heating (10 min at 43°C and possible dependence of this effect on changes in the activities of enzymes producing and scavenging reactive oxygen species (ROS were investigated. Treatment of coleoptiles with 10 μM 4-HBA resulted in enhancing of superoxide anion-radical generation and maintaining of hydrogen peroxide content there in. Increasing of the rate of ROS production was significantly suppressed by inhibitors of NADPH oxidase (α-naphthol and peroxidase (salicylhydroxamic acid. Under the influence of 4-HBA the activities of superoxide dismutase and apoplastic forms of peroxidase were increased. The activity of oxalate oxidase and catalase has not changed. Exogenous 4-HBA improved coleoptiles heat resistance and its effects were comparable with the influence of salicylic acid. Antioxidant agent BHT (butylhydroxytoluene, inhibitors of NADPH oxidase and peroxidase significantly reduced the increasing of wheat coleoptiles heat resistance, caused by 4-HBA action. It was concluded that 4-HBA influence on coleoptiles heat resistance is realized with the ROS mediation.

    Assurance of supply is a crucial objective for producers and consumers of oil and gas. A basic requirement to meet this objective is that producers and transmitters have sufficient economic incentives and capabilities to assure a desired degree of supply. The topic of this paper is to evaluate these incentives from a broad perspective. We examine economic trade-offs inherent in a delay of production, including reputational issues, as well as contract incentives for gas sellers, drilling companies, and oil service companies.

    Energy Technology Data Exchange (ETDEWEB)

    1992-12-01

    Adaptive, responsive and innovative management will be required for utilities to navigate successfully the challenges and uncertainties facing the electric industry in the 1990s. Regulatory schemes riddled with inconsistent and contradictory signals will impede the best-intentioned efforts of utility managers to develop and implement integrated resource plans. Effective reform in this area requires regulators to undertake a thorough review of incentives provided by the rate-setting process, an willingness to entertain alternative approaches and risks, and shifting the rewards of ratemaking to better utility earnings with management's performance and ratepayer interests. This article highlights a number of alternative rate-setting approaches that the New York Public Service Commission has adopted or considered in recent years. 16 refs.

  5. Incentive contracts for development projects

    Finley, David T.; Smith, Byron; DeGroff, B.

    2012-09-01

    Finding a contract vehicle that balances the concerns of the customer and the contractor in a development project can be difficult. The customer wants a low price and an early delivery, with as few surprises as possible as the project progresses. The contractor wants sufficient cost and schedule to cover risk. Both want to clearly define what each party will provide. Many program offices do not want to award cost plus contracts because their funding sources will not allow it, their boards do not want an open ended commitment, and they feel like they lose financial control of the project. A fixed price incentive contract, with a mutually agreed upon target cost, provides the owner with visibility into the project and input into the execution of the project, encourages both parties to save costs, and stimulates a collaborative atmosphere by aligning the respective interests of customers and contractors.

  6. A New Robust Decoupled Control of the Stator Active and Reactive Currents for Grid-Connected Doubly-Fed Induction Generators

    Directory of Open Access Journals (Sweden)

    Ahmad Bashar Ataji

    2016-03-01

    Full Text Available This paper addresses the grid-connected variable speed doubly-fed induction generator, and proposes a new decoupled control to replace the conventional decoupled active and reactive powers (P-Q control. The proposed decoupled control is based on decoupling the stator active and reactive currents, in contrast with the conventional decoupled P-Q control, which is based on decoupling the stator active and reactive powers by forcing the stator d- or q-voltage to zero. The proposed decoupled control has all the advantages of the conventional decoupled P-Q control such as constant switching frequency and robustness against slip angle inaccuracy, and it has some additional advantages: The proposed control requires less machine parameters; for the controller design, it requires the stator-to-rotor turns ratio only; for the online calculation, it does not requires any machine parameter. The proposed decoupled control is more flexible and robust since the control is independent of the grid voltage orientation. It is robust against variation in the grid voltage amplitude. Several experiments are carried out using a 1.1 kW doubly-fed induction generator (DFIG, and the results support the proposed decoupled control and demonstrate some of its advantages.

    2010-01-01

    This paper provides a comprehensive overview of the main tax incentives used in the EU-27 member states (MSs) to promote green electricity. Sixteen MSs use tax incentives to promote green electricity simultaneously with other promotion measures, especially quota obligations and price regulation. However, not all available technologies are promoted. For example, six MSs (Germany, Romania, Slovak Republic, Denmark, Sweden and Poland) have included an exemption on the payments of excise duties for electricity when the electricity is generated from renewable energy sources (RES). This tax incentive is the most widely used. Limited tax incentives in personal income tax are available in Belgium, France, Czech Republic and Luxembourg. In corporate tax, tax incentives consist mainly of a deduction in the taxable profit (Belgium, Greece, Czech Republic and Spain). Lower tax rates in VAT are applied in three MSs, France, Italy and Portugal. Only Spain and Italy use effective tax incentives in property tax. As a great diversity of tax incentives has been used to promote green electricity, this adds another difficulty to the EU objective of providing a renewable energy policy framework, but also it offers a useful set of case studies which can be used to inform EU policy development.

As a great diversity of tax incentives has been used to promote green electricity, this adds another difficulty to the EU objective of providing a renewable energy policy framework, but also it offers a useful set of case studies which can be used to inform EU policy development.

    Full Text Available In modern conditions activity of small innovative business, as the most flexible component of the innovation economy of the country is particularly important. However, due to the specifics of their activities small innovative business needs state support, including in the field of a tax policy. In this connection, consideration of tax incentives for small innovative business activity is relevant and timely. The purpose of this study is to identify the main directions of improvement of tax incentives for small innovative business in Russia through the use of foreign experience. The study used data analysis and comparisons to identify features of the tax incentives of small innovative business in Russia and abroad. In determining the main directions of improving, the study used the method of forecasting on the basis of the results of the analysis and comparison. The article described the basic instruments of tax incentives for activities of small innovation business in Russia. The article analyzed foreign experience of application of tax privileges and preferences. The article developed and substantiated recommendations on the improvement of the Russian system of tax incentives of activity of small innovative business. The authors make conclusion that the Russian system of tax incentives is ineffective and needs to be reformed by increasing the number of tax benefits, and the development of a special tax regime through the use of foreign experience.

    This paper considers distribution networks fea- turing distributed energy resources, and designs incentive-based mechanisms that allow the network operator and end-customers to pursue given operational and economic objectives, while concurrently ensuring that voltages are within prescribed limits. Two different network-customer coordination mechanisms that require different amounts of information shared between the network operator and end-customers are developed to identify a solution of a well-defined social-welfare maximization prob- lem. Notably, the signals broadcast by the network operator assume the connotation of prices/incentives that induce the end- customers to adjust the generated/consumed powers in order to avoid the violation of the voltage constraints. Stability of the proposed schemes is analytically established and numerically corroborated.

    With increased interest in energy efficiency in recent years, energy efficiency portfolio standards (EEPS) have gained popularity in state policymaking. This analysis employed New Jersey specific data to compare two incentive based approaches to EEPS implementation: rebates and white certificates. Quantitative modeling suggests that white certificate approaches that depend on market-clearing prices generate much larger upfront incentive outlays than rebate programs. They do not however increase societal burden. Both programs overcome high upfront efficiency measure costs and both recoup the expenses over the long run. Administration costs and participation rates can affect this dynamic however and require additional research to determine which approaches are most cost effective for various energy efficiency measures.

    Full Text Available The incentives of health care expenditure (HCE have been a topic of discussion in the USA (Obama reforms and in Europe (adjustment to debt crisis. There are competing views of institutional versus GDP (unit income elasticity and productivity related factors of growth of expenditure. However ageing of populations, technology change and economic incentives related to institutions are also key drivers of growth according to the OECD and EU’s AWG committee. Simulation models have been developed to forecast the growth of social expenditure (including HCEs to 2050. In this article we take a historical perspective to look at the institutional structures and their relationship to HCE growth. When controlling for age structure, price developments, doctor density and in-patient and public shares of expenditures, we find that fee-for-service in primary care, is according to the results, in at least 20 percent more costly than capitation or salary remuneration. Capitation and salary (or wage remuneration are at same cost levels in primary care. However we did not find the cost lowering effect for gatekeeping which could have been expected based on previous literature. Global budgeting 30 (partly DRG based percent less costly in specialized care than other reimbursement schemes like open contracting or volume based reimbursement. However the public integration of purchaser and provider cost seems to result to about 20 higher than public reimbursement or public contracting. Increasing the number of doctors or public financing share results in increased HCEs. Therefore expanding public reimbursement share of health services seems to lead to higher HCE. On the contrary, the in-patient share reduced expenditures. Compared to the previous literature, the finding on institutional dummies is in line with similar modeling papers. However the results for public expansion of services is a contrary one to previous works on the subject. The median lag length of

    Previous research suggests that pigeons and rats show differences in their behavioral adjustments in spaced-trial, incentive-downshift situations. Also, Papini and Pellegrini [Papini, M.R., Pellegrini, S., 2006. Scaling relative incentive value in consummatory behavior. Learn. Motiv. 37, 357-378] and Pellegrini and Papini [Pellegrini, S., Papini, M.R., 2007. Scaling relative incentive value in anticipatory behavior. Learn. Motiv. 38, 128-154] showed that changes in the rat's lever-pressing performance, runway running, and consumption of sucrose solutions after downshifts in incentive magnitude were a function of the ratio of postshift/preshift incentive magnitudes. Here, two experiments using a Pavlovian autoshaping procedure studied the adjustment of pigeons and rats to changes in incentive magnitude. In Experiment 1, pigeons received light-food pairings, whereas in Experiment 2, rats received lever-sucrose pairings. As a result, key-pecking and lever-pressing developed in each experiment, respectively. Preshift incentive magnitudes were downshifted so as to obtain postshift/preshift ratios of 0.125 and 0.25. Pigeons responded during the postshift phase according to the preshift incentive value and independently of the ratio value. However, rats showed ratio constancy, responding during the postshift in accordance with the postshift/preshift ratio, rather than with the absolute magnitudes of either the preshift or postshift incentives. These results support the comparative hypothesis that the mechanisms underlying ratio constancy during incentive downshifts are unique to mammals.

  17. Developing Incentives for Data Sharing in Ecology

    Duke, C. S.

    2010-12-01

    In recent decades, ecological scientists’ capacity for generating data has increased at an exponential rate. The need to organize data in ways useful for problem solving has similarly accelerated in the face of global challenges such as climate change, widespread species extinctions, and declines in biodiversity. In light of these trends, virtually every field of ecology would benefit from more comprehensive and systematic documentation and publication of metadata, combined with general availability of data through online sources. Both organizations and individual scientists need to take action to meet these needs. In response, the Ecological Society of America (ESA) has led a series of NSF-sponsored workshops to help scientists find common ground on how to make data more readily discoverable and accessible in their own disciplines. The most recent of these focused in the development of incentives for data sharing, both at the individual and organizational level. This presentation will summarize the workshop recommendations, with a focus on preservation, curation, and access to data; access to analytical and visualization tools; and the need to make data archiving simple and routine. The roles of funders and publishers of research are also key and will be highlighted.

  18. Investment incentives in the Korean electricity market

    Park, Jung-Yeon; Ahn, Nam-Sung; Yoon, Yong-Beum; Koh, Kyung-Ho; Bunn, Derek W.

    2007-01-01

    This paper develops a model-based analysis of the effects of various capacity incentive systems on new investment in the Korean electricity market. The restructuring process in Korea allocated power generation to six firms, competing within a wholesale market, albeit strictly on a cost basis. Because of this cost-based pool, capacity payments were also introduced to encourage new investment. However, it is an open question whether the current fixed capacity payment scheme is enough to secure resource adequacy, and consideration is being given to alternative mechanisms such as the use of LOLP. Using a detailed market simulation model, based on system dynamics, we compare these approaches in terms of how they may influence the investors' decisions and thereby determine the system reserve margin. The simulation results suggest that there may be serious problems in staying with the current fixed capacity payments in order to achieve resource adequacy. In contrast, an LOLP-based capacity mechanism may, in the longer term, increase the reserve margin compared with a fixed capacity payment. More generally, this paper indicates how crucial the effective modeling of the investment behavior of the independent power producers is for adequate policy support, even if they only constitute a fringe in a substantially centrally influenced market

    A method for PWM control of inverter circuits in photovoltaic power generation systems is developed to connect them to utility power supply systems for residences. For controlling sine-wave PWM inverters, it is possible to control a basic wave voltage for inverter output in a range from 0 to 100% by the on-off actions of the switching device, after comparing heights of the carrier wave (triangular wave) and signal wave (sine wave) with each other, to change the signal wave amplitude. The authors has proposed a new method in which the carrier wave is swung over the positive and negative regions corresponding to the positive and negative signal wave, and the on-off phase of the switching device is deviated a little from the phase determined by comparing heights of the carrier and signal waves with each other. Basic wave voltage for inverter output can be increased by about 18%, e.g., at a modulation degree of 80%, from the level obtained by the conventional method. In other words, it is possible to reduce photovoltaic cell array voltage by 15% (i.e., 1/1.18 = 0.85 times) to obtain the same voltage as given by the conventional method. Number of cell modules can be reduced by that, accordingly. The effect of the harmonic component is found to be small. 7 refs., 9 figs., 3 tabs.

  5. A reexamination of the incentives for actinide burning

    International Nuclear Information System (INIS)

    Croff, A.G.; Forsberg, C.W.; Ludwig, S.B.

    1990-01-01

    Actinide burning (AB) is a concept that would greatly reduce the amounts of long-lived transuranic (TRU) nuclides in wastes going to the repository. The concept is implemented by intensified processing to reduce actinide losses to wastes and subsequent recycling of the actinides to liquid-metal reactors (LMRs). As a result, AB may simultaneously (a) simplify waste management by fissioning the TRU nuclides to shorter lived nuclides, (b) generate electricity, and (c) greatly extend uranium resources. In previous studies, researchers at the Oak Ridge National Laboratory compared the long-term repository risk reduction from AB to increases in cost and contemporary risk. They concluded that incentives for AB did not exist. Similar conclusions were reached by European investigators. During the decade since these studies, there have been two major developments related to the incentives for AB. The first is that the challenges inherent in characterizing, licensing, and funding a repository have become clearer and are larger than originally anticipated. The second development is the establishment of an Environmental Protection Agency (EPA) standard and US Nuclear Regulatory Commission (NRC) criteria to provide a specific measure of repository acceptability, as opposed to the many assumptions and calculations inherent in previous analyses. Consequently, the incentives for AB have been reexamined in the context of these developments and are discussed in this paper

  9. Impact of government incentives in the profitability of green energy production using fuel cells in Colombia.

    Directory of Open Access Journals (Sweden)

    Bernardo A. Potosí-Guerrero

    2016-07-01

    Full Text Available Fuel cells are a technological alternative to produce green energy, however, high costs make fuel cell a non-profitable option. This paper analyses the impact of the Colombian government incentives in the profitability of fuel cells. The analysis is based on the total operation cost of the fuel cell in three representative applications: residential, office and building elevator. The economic viability of fuel cell generation in those cases is contrasted with classical solutions like diesel generators and standard grid to provide a reference framework. Such results enable to evaluate the effectiveness of the Colombian government incentives in promoting the use of fuel cells over other less environmental-friendly options such as diesel generators. Finally, new incentives are proposed by subsidies offered by other countries with higher fuel cell penetration into their electric market. All the analyses are supported in simulations performed with a mathematical model parameterized using the characteristics of commercial devices.

  10. Incentives for early adoption of carbon capture technology

    Comello, Stephen; Reichelstein, Stefan

    2014-01-01

    We analyze a policy proposal for regulating the next generation of baseload electricity generation facilities in the United States. The cornerstone of this regulation is a (hypothetical) EPA mandate for an emission standard of 80 kg of CO 2 per MWh of electricity generated. The mandate would go into effect at the end of 2027 for all power generating facilities that come into operation after 2017. Fossil-fuel power plants could meet the standard by capturing between 80 and 90% of their current CO 2 emissions. While the initial cost of complying with this standard is relatively high for first-of-a-kind facilities, learning effects are projected to reduce this cost substantially by the end of 2027, provided new facilities consistently adopt carbon capture technology in the intervening years. We identify a combination of investment- and production tax credits that provide the required incentives for new facilities to be willing to comply with the standard ahead of the mandate. Due to the anticipated learning effects, the incremental cost associated with the stricter emission limit is projected to about 1.2¢ per kWh of electricity in the long run. - Highlights: • Study the cost effects of a CO 2 emission standard for natural gas power plants. • The standard requires the deployment of carbon capture technology. • Future compliance costs are reduced through learning effects. • Identify tax incentives that induce early technology adoption. • Early adoption results in relatively modest electricity cost increases

In this sense, the aim of this study was to verify the consistency and form of disclosure of the information disclosed by the Corporation Publicly Traded in southern Brazil, from the perspective of reducing the tax burden and the amount allocated to the Culture. The sample consisted of 27 Corporate Capital Open in southern Brazil and analyzed its financial statements, accompanying notes and supplementary reports through pre-established keywords, characterizing the research as descriptive, with a qualitative approach. The results showed the importance of the Notes, the Management Report and additional reports as Social and Sustainability Report. These reports had relevant information and helpful research. However, many of them did not have clear information about the tax incentives for culture. Some companies released the tax incentive culture along with other incentives, such as the Workers Food Program - PAT, which did not allow detailed analysis of the data. We found cases of disagreement between the Ministry of Culture and information disclosed statements. In some cases, were observed lack of information about the tax incentives in the statements and supplementary reports. It was concluded that the disclosure is lower than necessary, because only four out of a total of twenty seven companies analyzed, reported consistent, complete and appropriate on tax incentives for culture.

    Full Text Available The attribution of incentive salience to reward associated cues is critical for motivation and the pursuit of rewards. Disruptions in the integrity of the neural systems controlling these processes can lead to avolition and anhedonia, symptoms that cross the diagnostic boundaries of many neuropsychiatric illnesses. Here, we consider whether the habenula (Hb, a region recently demonstrated to encode negatively valenced events, also modulates the attribution of incentive salience to a neutral cue predicting a food reward. The Pavlovian autoshaping paradigm was used in the rat as an investigative tool to dissociate Pavlovian learning processes imparting strictly predictive value from learning that attributes incentive motivational value. Electrolytic lesions of the fasciculus retroflexus (fr, the sole pathway through which descending Hb efferents are conveyed, significantly increased incentive salience as measured by conditioned approaches to a cue light predictive of reward. Conversely, generation of a fictive Hb signal via fr stimulation during CS+ presentation significantly decreased the incentive salience of the predictive cue. Neither manipulation altered the reward predictive value of the cue as measured by conditioned approach to the food. Our results provide new evidence supporting a significant role for the Hb in governing the attribution of incentive motivational salience to reward predictive cues and further imply that pathological changes in Hb activity could contribute to the aberrant pursuit of debilitating goals or avolition and depression-like symptoms.

    Full Text Available In order to invest there are some incentives needed, including among them, certainly, the ones discussed and analysed in the scientific literature such as: specific earning chances (expectations of each participant (wage, profit, dividend, budget revenue, etc., potential investor’s general or current state, etc.. Less visible incentives from complex areas not obviously related to the investment are, however, less considered. Among these could be incentives arising from inherited or education and culture transmitted philosophy, generally regarding earnings, business and investment. We notice these incentives in case of FDI in different shades and intensities.Investor’s decision to acquire, sell or to carry out projects in a particular area, region or country is not only due to purely economic, commercial or financial reasoning. In such operations, meeting among businessmen, managers and other professionals in the field is, first of all, meeting in specific circumstances, among more or less different cultures.Both theory and practice must be concerned in what way and to what extent these factors influence the investment intention, outcome and yield. Our study proposes a list of the most important cultural type incentives for investment (mainly FDI, based on a set of cases, through a logical and empirical research, using some of the most relevant and recent studies and several real situations to which we got access. These are early data and analysis that will allow us to draw attention to the problem and to develop further research to reach generalizable results

    Berdud, Mikel; Cabasés, Juan M; Nieto, Jorge

    It has been established in the literature that workers within public organisations are intrinsically motivated. This paper is an empirical study of the healthcare sector using methods of qualitative analysis research, which aims to answer the following hypotheses: 1) doctors are intrinsically motivated; 2) economic incentives and control policies may undermine doctors' intrinsic motivation; and 3) well-designed incentives may encourage doctors' intrinsic motivation. We conducted semi-structured interviews à-la-Bewley with 16 doctors from Navarre's Healthcare Service (Servicio Navarro de Salud-Osasunbidea), Spain. The questions were based on current theories of intrinsic motivation and incentives to test the hypotheses. Interviewees were allowed to respond openly without time constraints. Relevant information was selected, quantified and analysed by using the qualitative concepts of saturation and codification. The results seem to confirm the hypotheses. Evidence supporting hypotheses 1 and 2 was gathered from all interviewees, as well as indications of the validity of hypothesis 3 based on interviewees' proposals of incentives. The conclusions could act as a guide to support the optimal design of incentive policies and schemes within health organisations when healthcare professionals are intrinsically motivated.

    Peat soils act as important carbon sinks, but they also release large amounts of dissolved organic carbon (DOC) to the aquatic system. The DOC export is strongly tied to the export of soluble heavy metals. The accumulation of potentially toxic substances due to anthropogenic activities, and their natural export from peat soils to the aquatic system is an important health and environmental issue. However, limited knowledge exists as to how much of these substances are mobilized, how they are mobilized in terms of flow pathways and under which hydrometeorological conditions. In this study, we report from a combined experimental and modelling effort to provide greater process understanding from a small, lead (Pb) and arsenic (As) contaminated upland peat catchment in northwestern Germany. We developed a minimally parameterized, but process-based, coupled hydrology-biogeochemistry model applied to simulate detailed hydrometric and biogeochemical data. The model was based on an initial data mining analysis, in combination with regression relationships of discharge, DOC and element export. We assessed the internal model DOC-processing based on stream-DOC hysteresis patterns and 3-hourly time step groundwater level and soil DOC data (not used for calibration as an independent model test) for two consecutive summer periods in 2013 and 2014. We found that Pb and As mobilization can be efficiently predicted from DOC transport alone, but Pb showed a significant non-linear relationship with DOC, while As was linearly related to DOC. The relatively parsimonious model (nine calibrated parameters in total) showed the importance of non-linear and rapid near-surface runoff-generation mechanisms that caused around 60% of simulated DOC load. The total load was high even though these pathways were only activated during storm events on average 30% of the monitoring time - as also shown by the experimental data. Overall, the drier period 2013 resulted in increased nonlinearity, but

    Within the Malaysian context, incentive system in scientific publishing rewards authors for publishing journal articles or conference papers that are indexed by Scopus. At Universiti Tun Hussein Onn Malaysia, the incentive system is going into its third year in operational. The main challenge lies in preparing the evidences as required by the application guideline. This paper presents an online module for publication incentive within the University Publication Information System (SMPU). The module was developed using the Scrum methodology based on the existing workflow of paper-based application. The module is hoped to increase the quality of the system deliverables of SMPU as well as having the ability to cope with change of university requirements in the future.

    Costs related with restoration efforts, as well as the economic incentives, are fundamental issues that have not been fully considered from a formal standpoint. Through the analysis of restoration trials in collaboration with an indigenous community in western Mexico, we analyzed economic issues related with the restoration trials themselves, and with the economic context that gives incentives for ecological restoration. We reach to the conclusion that the cost-benefit relationship of the restoration process by itself can be straightforward calculated in some cases, calculating economic benefits accrued from the diversity restored to ecosystem is more difficult. In terms of the incentives for biodiversity restoration, we concluded that in many cases, economic variables out of the control of those involved in restoration are determinant.

  4. Generic host state incentive report. Draft

    Even the most carefully designed and operated low-level radioactive waste management facility will present potential risks and costs to nearby residents. Individuals who live near these facilities may receive some benefits, but they also bear the brunt of any adverse impacts. It is with this in mind that various siting techniques have been developed. Before any ''extra'' compensation or incentive can be discussed, however, it must first be clearly demonstrated that these facilities protect public health and the environment. This report addresses five distinct areas as follows: mitigation measure to prevent or reduce the impact of the facility; incentives and compensation techniques that might make a facility more acceptable; the use of agreement building in order to develop an arrangement between the host community and a facility proponent; the importance of economics resulting from a typical regional low-level radioactive waste facility; and the role of state government in promoting and legitimizing the use of incentives. 6 tabs

    Response to a reinforcer is affected by prior experience with different reward values of that reward, a phenomenon known as incentive relativity. Two different procedures to study this phenomenon are the incentive downshift (ID) and the consummatory anticipatory negative contrast (cANC), the former is an emotional-cognitive protocol and the latter cognitive one. Aged rodents, as also well described in aged humans, exhibit alterations in cognitive functions. The main goal of this work was to evaluate the effect of age in the incentive' assessment using these two procedures. The results indicated that aged rats had an adequate assessment of the rewards but their performance is not completely comparable to that of young subjects. They recover faster from the ID and they had a cognitive impairment in the cANC. The results are discussed in relation to age-related changes in memory and emotion.

    2012-12-01

    All communities have common resources that are vulnerable to selfish motives. The current paper explores this challenge in the specific case of the urban commons, defined as the public spaces and scenery of city neighborhoods. A theoretical model differentiates between individual incentives and social incentives for caring for the commons. The quality of a commons is defined as the level of physical (e.g., loose garbage) and social (e.g., public disturbances) disorder. A first study compared levels of disorder across the census block groups of a single city; the second compared the disorder generated by individual addresses in two neighborhoods. Each study found that homeownership, an individual incentive, was the main predictor of disorder. Owner-occupied parcels generated less disorder than their renter-occupied neighbors, but both parcel types produced less disorder in a neighborhood with greater homeownership. The results emphasize the need for considering both individual and social incentives for group-beneficial behaviors.

    The dearth of health workers in rural settings in Lao People's Democratic Republic (PDR) and other developing countries limits healthcare access and outcomes. In evaluating non-wage financial incentive packages as a potential policy option to attract health workers to rural settings, understanding the expected costs and effects of the various programs ex ante can assist policy-makers in selecting the optimal incentive package. We use discrete choice experiments (DCEs), costing analyses and recent empirical results linking health worker density and health outcomes to estimate the future location decisions of physicians and determine the cost-effectiveness of 15 voluntary incentives packages for new physicians in Lao PDR. Our data sources include a DCE survey completed by medical students (n = 329) in May 2011 and secondary cost, economic and health data. Mixed logit regressions provide the basis for estimating how each incentive package influences rural versus urban location choice over time. We estimate the expected rural density of physicians and the cost-effectiveness of 15 separate incentive packages from a societal perspective. In order to generate the cost-effectiveness ratios we relied on the rural uptake probabilities inferred from the DCEs, the costing data and prior World Health Organization (WHO) estimates that relate health outcomes to health worker density. Relative to no program, the optimal voluntary incentive package would increase rural physician density by 15% by 2016 and 65% by 2041. After incorporating anticipated health effects, seven (three) of the 15 incentive packages have anticipated average cost-effectiveness ratio less than the WHO threshold (three times gross domestic product [GDP] per capita) over a 5-year (30 year) period. The optimal package's incremental cost-effectiveness ratio is $1454/QALY (quality-adjusted life year) over 5 years and $2380/QALY over 30 years.

  13. A Simulation Modeling Framework to Optimize Programs Using Financial Incentives to Motivate Health Behavior Change.

    2016-01-01

    While increasingly popular among mid- to large-size employers, using financial incentives to induce health behavior change among employees has been controversial, in part due to poor quality and generalizability of studies to date. Thus, fundamental questions have been left unanswered: To generate positive economic returns on investment, what level of incentive should be offered for any given type of incentive program and among which employees? We constructed a novel modeling framework that systematically identifies how to optimize marginal return on investment from programs incentivizing behavior change by integrating commonly collected data on health behaviors and associated costs. We integrated "demand curves" capturing individual differences in response to any given incentive with employee demographic and risk factor data. We also estimated the degree of self-selection that could be tolerated: that is, the maximum percentage of already-healthy employees who could enroll in a wellness program while still maintaining positive absolute return on investment. In a demonstration analysis, the modeling framework was applied to data from 3000 worksite physical activity programs across the nation. For physical activity programs, the incentive levels that would optimize marginal return on investment ($367/employee/year) were higher than average incentive levels currently offered ($143/employee/year). Yet a high degree of self-selection could undermine the economic benefits of the program; if more than 17% of participants came from the top 10% of the physical activity distribution, the cost of the program would be expected to always be greater than its benefits. Our generalizable framework integrates individual differences in behavior and risk to systematically estimate the incentive level that optimizes marginal return on investment. © The Author(s) 2015.

    Martin, Adam; Suhrcke, Marc; Ogilvie, David

    2012-01-01

    Context Financial incentives, including taxes and subsidies, can be used to encourage behavior change. They are common in transport policy for tackling externalities associated with use of motor vehicles, and in public health for influencing alcohol consumption and smoking behaviors. Financial incentives also offer policymakers a compromise between “nudging,” which may be insufficient for changing habitual behavior, and regulations that restrict individual choice. Evidence acquisition The literature review identified studies published between January 1997 and January 2012 of financial incentives relating to any mode of travel in which the impact on active travel, physical activity, or obesity levels was reported. It encompassed macroenvironmental schemes, such as gasoline taxes, and microenvironmental schemes, such as employer-subsidized bicycles. Five relevant reviews and 20 primary studies (of which nine were not included in the reviews) were identified. Evidence synthesis The results show that more-robust evidence is required if policymakers are to maximize the health impact of fiscal policy relating to transport schemes of this kind. Conclusions Drawing on a literature review and insights from the SLOTH (sleep, leisure, occupation, transportation, and home-based activities) time-budget model, this paper argues that financial incentives may have a larger role in promoting walking and cycling than is acknowledged generally.

    The objectives of this study were to explore RN perceptions regarding barriers/challenges and incentives/supports for BSN completion and identify recommendations to increase RN BSN completion. The Institute of Medicine's 2011 The Future of Nursing report recommended the proportion of RNs with a BSN increase to 80% by 2020. This qualitative study included 41 RNs who participated in 1 of 6 focus groups based on their BSN completion status. Primary themes were sacrifices, barriers/challenges, incentives/supports, value, how to begin, and pressure. Primary BSN completion barriers/challenges were work-life balance and economic issues. Incentives/supports identified were financial compensation, assistance from employer and academic institution, and encouragement from family. Institutional strategies recommended for increasing BSN completion rates were improved access to education and financial support facilitated by collaboration between hospitals and academic institutions. Exploring RN barriers/challenges and incentives/supports for BSN completion can lead to implementation of institutional strategies, such as tuition reimbursement and academic collaboration.

  11. Creating New Economic Incentives for Repurposing Generic Drugs for Unsolved Diseases Using Social Finance.

    Bloom, Bruce E

    2015-12-01

    Repurposing research improves patient lives by taking drugs approved for one disease and clinically testing them to create a treatment for a different disease. Repurposing drugs that are generic, inexpensive, and widely available and that can be taken in their current dosage and formulation in the new indication provide a quick, affordable, and effective way to create "new" treatments. However, generic drug repurposing often provides no profit potential, and so there is no economic incentive for industry to pursue this, and philanthropy and government funds are often insufficient. One way to create new economic incentive for the repurposing of generic drugs is through social finance. This perspective describes how social finance can create a new economic incentive by using a social impact bond, or similar financial structure, to repay for-profit investors who fund the repurposing research from the proceeds of healthcare cost reductions generated when these affordable, effective, and widely available repurposed therapies improve healthcare outcomes.

    Radiology report signature time (ST) can be a substantial component of total report turnaround time. Poor turnaround time resulting from lengthy ST can adversely affect patient care. The combination of technology adoption with financial incentive was evaluated to determine if ST improvement can be augmented and sustained. This prospective study was performed at a 751-bed, urban, tertiary care adult teaching hospital. Test-site imaging volume approximated 48,000 examinations per month. The radiology department has 100 trainees and 124 attending radiologists serving multiple institutions. Over a study period of 4 years and 4 months, three interventions focused on radiologist signature performance were implemented: 1) a notification paging application that alerted radiologists when reports were ready for signature, 2) a picture archiving and communications systems (PACS)-integrated speech recognition report generation system, and 3) a departmental financial incentive to reward radiologists semiannually for ST performance. Signature time was compared before and after the interventions. Wilcoxon and linear regression statistical analyses were used to assess the significance of trends. Technology adoption (paging plus speech recognition) reduced median ST from >5 to 24 to 15 to 18 hours (P financial incentive further improved 80th-percentile ST to 4 to 8 hours (P Technology interventions coupled with financial incentive can result in synergistic and sustainable improvement in radiologist report-signing behavior. The addition of a financial incentive leads to better performance than that achievable through technology alone.

  18. About Connections

    Directory of Open Access Journals (Sweden)

    Kathleen S Rockland

    2015-05-01

    Full Text Available Despite the attention attracted by connectomics, one can lose sight of the very real questions concerning What are connections? In the neuroimaging community, structural connectivity is ground truth and underlying constraint on functional or effective connectivity. It is referenced to underlying anatomy; but, as increasingly remarked, there is a large gap between the wealth of human brain mapping and the relatively scant data on actual anatomical connectivity. Moreover, connections have typically been discussed as pairwise, point x projecting to point y (or: to points y and z, or more recently, in graph theoretical terms, as nodes or regions and the interconnecting edges. This is a convenient shorthand, but tends not to capture the richness and nuance of basic anatomical properties as identified in the classic tradition of tracer studies. The present short review accordingly revisits connectional weights, heterogeneity, reciprocity, topography, and hierarchical organization, drawing on concrete examples. The emphasis is on presynaptic long-distance connections, motivated by the intention to probe current assumptions and promote discussions about further progress and synthesis.

  19. Effects of Maternal Work Incentives on Youth Crime.

    Corman, Hope; Dave, Dhaval; Kalil, Ariel; Reichman, Nancy E

    2017-12-01

    This study exploits differences in the implementation of welfare reform across states and over time to identify causal effects of maternal work incentives, and by inference employment, on youth arrests between 1988 and 2005, the period of time during which welfare reform unfolded. We consider both serious and minor crimes as classified by the Federal Bureau of Investigation, consider differential effects by the youth's gender and age, investigate the extent to which effects were stronger in states with more stringent work incentive policies and larger welfare caseload declines, and use a number of different model specifications to assess robustness and patterns. We find that welfare reform led to reduced arrests for minor crime among youth ages 15-17 years by 9-11 %, with similar estimates for males and females, but that it did not affect youth arrests for serious crimes. The results from this study add to a scant knowledge base about the effects of maternal employment on adolescent behavior by exploiting a large-scale social experiment that greatly increased employment of low-skilled women. The results also provide some support for the widely-embraced argument that welfare reform would discourage undesirable social behavior, not only of mothers, but also of the next generation.

    Microgrids can provide an avenue for increasing the amount of distributed generation and delivery of electricity, where control is more dispersed and quality of service is locally tailored to end-use requirements. Much of this functionality is very different from the predominant utility model to date of centralized power production which is then transmitted and distributed across long distances with a uniform quality of service. This different functionality holds much promise for positive change, in terms of increasing reliability, energy efficiency, and renewable energy while decreasing and carbon emissions. All of these functions should provide direct cost savings for customers and utilities as well as positive externalities for society. As we have seen from the international experience, allowing microgrids to function in parallel with the grid requires some changes in electricity governance and incentives to capture cost savings and actively price in positive externalities. If China can manage to implement these governance changes and create those incentive policies, it will go beyond the establishment of a successful microgrid demonstration program and become an international leader in microgrid deployment.

    This paper analyzes the incentive effects of a hybrid revenue cap on a regulated monopolistic firm using non-discriminatory two-part pricing. It is shown that the fixed and the variable part of the cap have different meanings in terms of regulation - the fixed part of a hybrid revenue cap should be used to control the profit level of the regulated firm while the variable part should be used to control the social efficiency level. Since detailed information about the firm's cost function is required to determine the revenue cap parameters, the overall conclusion is that revenue caps are a rather bad idea in the area of incentive regulation.

    Utility incentive programs remain one of the most significant means of deploying commercialized, but underutilized building technologies to scale. However, these programs have been largely limited to component-based products (e.g., lamps, RTUs). While some utilities do provide ‘custom’ incentive programs with whole building and system level technical assistance, these programs require deeper levels of analysis, resulting in higher program costs. This results in custom programs being restricted to utilities with greater resources, and are typically applied mainly to large or energy-intensive facilities, leaving much of the market without cost effective access and incentives for these solutions. In addition, with increasingly stringent energy codes, cost effective component-based solutions that achieve significant savings are dwindling. Building systems (e.g., integrated façade, HVAC and/or lighting solutions) can deliver higher savings that translate into large sector-wide savings if deployed at the scale of these programs. However, systems application poses a number of challenges – baseline energy use must be defined and measured; the metrics for energy and performance must be defined and tested against; in addition, system savings must be validated under well understood conditions. This paper presents a sample of findings of a project to develop validated utility incentive program packages for three specific integrated building systems, in collaboration with Xcel Energy (CO, MN), ComEd, and a consortium of California Public Owned Utilities (CA POUs) (Northern California Power Agency(NCPA) and the Southern California Public Power Authority(SCPPA)). Furthermore, these program packages consist of system specifications, system performance, M&V protocols, streamlined assessment methods, market assessment and implementation guidance.

    Investments in renewable energy are more attractive due to the contribution of two key federal tax incentives. The investment tax credit (ITC) and the Modified Accelerated Cost Recovery System (MACRS) depreciation deduction may apply to energy storage systems such as batteries depending on who owns the battery and how the battery is used. The guidelines in this fact sheet apply to energy storage systems installed at the same time as the renewable energy system.

    This paper considers the optimal level of firm-specific training by taking into account the positive effect of training on the expected duration of workers’ current employment. In the framework of an efficiency wage model, a short expected job tenure represents a disamenity that reduces the penalty from shirking. As this disamenity increases, workers have an incentive to continue providing a positive level of effort only if they are compensated by a higher wage. We endogenize the employment...

    Engaging private landowners in conservation activities for imperiled species is critical to maintaining and enhancing biodiversity. Market-based approaches can incentivize conservation behaviors on private lands by shifting the benefit-cost ratio of engaging in activities that result in net conservation benefits for target species. In the United States and elsewhere, voluntary conservation agreements with financial incentives are becoming an increasingly common strategy. While the influence of program design and delivery of voluntary conservation programs is often overlooked, these aspects are critical to achieving the necessary participation to attain landscape-scale outcomes. Using a sample of family-forest landowners in the southeast United States, we show how preferences for participation in a conservation program to protect an at-risk species, the gopher tortoise (Gopherus polyphemus), are related to program structure, delivery, and perceived efficacy. Landowners were most sensitive to programs that are highly controlling, require permanent conservation easements, and put landowners at risk for future regulation. Programs designed with greater levels of compensation and that support landowners' autonomy to make land management decisions can increase participation and increase landowner acceptance of program components that are generally unfavorable, like long-term contracts and permanent easements. There is an inherent trade-off between maximizing participation and maximizing the conservation benefits when designing a conservation incentive program. For conservation programs targeting private lands to achieve landscape-level benefits, they must attract a critical level of participation that creates a connected mosaic of conservation benefits. Yet, programs with attributes that strive to maximize conservation benefits within a single agreement (and reduce risks of failure) are likely to have lower participation, and thus lower landscape benefits.

    2016-01-01

    According to standard economic theory higher monetary incentives will lead to higher performance and higher effort independent of task, context, or individual. In many contexts this standard economic advice is implemented. Monetary incentives are, for example, used to enhance performance at workplace or to increase health-related behavior. However, the fundamental positive impact of monetary incentives has been questioned by psychologists as well as behavioral economists during the last decade, arguing that monetary incentives can sometimes even backfire. In this chapter, studies from proponents as well as opponents of monetary incentives will be presented. Specifically, the impact of monetary incentives on performance, prosocial, and health behavior will be discussed. Furthermore, variables determining whether incentives have a positive or negative impact will be identified. © 2016 Elsevier B.V. All rights reserved.

  13. Incentive or habit learning in amphibians?

    Directory of Open Access Journals (Sweden)

    Rubén N Muzio

    Full Text Available Toads (Rhinella arenarum received training with a novel incentive procedure involving access to solutions of different NaCl concentrations. In Experiment 1, instrumental behavior and weight variation data confirmed that such solutions yield incentive values ranging from appetitive (deionized water, DW, leading to weight gain, to neutral (300 mM slightly hypertonic solution, leading to no net weight gain or loss, and aversive (800 mM highly hypertonic solution leading to weight loss. In Experiment 2, a downshift from DW to a 300 mM solution or an upshift from a 300 mM solution to DW led to a gradual adjustment in instrumental behavior. In Experiment 3, extinction was similar after acquisition with access to only DW or with a random mixture of DW and 300 mM. In Experiment 4, a downshift from DW to 225, 212, or 200 mM solutions led again to gradual adjustments. These findings add to a growing body of comparative evidence suggesting that amphibians adjust to incentive shifts on the basis of habit formation and reorganization.

    Incentive-based demand response (IBDR) can guide customers to adjust their behaviour of electricity and curtail load actively. Meanwhile, distributed generation (DG) and energy storage system (ESS) can provide time for the implementation of IBDR. The paper focus on the reliability evaluation of microgrid considering IBDR. Firstly, the mechanism of IBDR and its impact on power supply reliability are analysed. Secondly, the IBDR dispatch model considering customer’s comprehensive assessment and the customer response model are developed. Thirdly, the reliability evaluation method considering IBDR based on Monte Carlo simulation is proposed. Finally, the validity of the above models and method is studied through numerical tests on modified RBTS Bus6 test system. Simulation results demonstrated that IBDR can improve the reliability of microgrid.

  16. Cattle producers' economic incentives for preventing bovine brucellosis under uncertainty.

    Science.gov (United States)

    Roberts, Trenton W; Peck, Dannele E; Ritten, John P

    2012-12-01

    Cattle in the Greater Yellowstone Ecosystem occasionally contract bovine brucellosis from free-ranging elk and bison. Cattle producers use a variety of brucellosis prevention activities to reduce their herds' risk of contracting brucellosis, such as: (1) having state agency personnel haze elk off private land, (2) fencing haystacks, (3) administering adult booster vaccination, (4) spaying heifers, (5) altering the winter-feeding schedule of cattle, (6) hiring riders to prevent cattle-elk commingling, and (7) delaying grazing on high-risk allotments. Their brucellosis prevention decisions are complicated, however, by several sources of uncertainty, including the following: a cattle herd's baseline risk of contracting brucellosis, the inherent randomness of brucellosis outbreaks, the cost of implementing prevention activities, and the activities' effectiveness. This study eliminates one source of uncertainty by estimating the cost of implementing brucellosis prevention activities on a representative cow/calf-long yearling operation in the southern GYE. It then reports the minimum level of effectiveness each prevention activity must achieve to justify investment by a risk-neutral producer. Individual producers face different levels of baseline risk, however, and the US government's brucellosis-response policy is constantly evolving. We therefore estimate breakeven levels of effectiveness for a range of baseline risks and government policies. Producers, animal health experts, and policymakers can use this study's results to determine which brucellosis prevention activities are unlikely to generate sufficient expected benefits to cover their cost of implementation. Results also demonstrate the influence of government policy on producers' incentives to prevent brucellosis. Policies that increase the magnitude of economic loss a producer incurs when their herd contracts brucellosis subsequently decrease prevention activities' breakeven levels of effectiveness, and

  17. Designing effective incentives for energy conservation in the public sector

    Science.gov (United States)

    Drezner, Jeffrey Alan

    Understanding why government officials behave in certain ways under particular circumstances is an important theme in political science. This research explores the design of policies and incentives targeted at public sector officials, in particular the use of market based policy tools in a non-market environment, and the influence of that organizational environment on the effectiveness of the policy. The research examines the case of Department of Defense (DoD) facility energy management. DoD energy policy includes a provision for the retention of savings generated by conservation activities: two-thirds of the savings is retained at the installation generating the savings, half to used for further investment in energy conservation, and half to be used for general morale, welfare, and recreation activities. This policy creates a financial incentive for installation energy managers to establish higher quality and more active conservation programs. A formal written survey of installation energy managers within DoD was conducted, providing data to test hypotheses regarding policy effectiveness and factors affecting policy implementation. Additionally, two detailed implementation case studies were conducted in order to gain further insights. Results suggest that policy design needs to account for the environment within which the policy will be implemented, particularly organizational culture and standard operating procedures. The retention of savings policy failed to achieve its intended outcome---retention of savings for re-investment in energy conservation---because the role required of the financial management community was outside its normal mode of operation and interests and the budget process for allocating resources did not include a mechanism for retention of savings. The policy design did not adequately address these start-up barriers to implementation. This analysis has shown that in order for retention of savings, or similar policies based on market

  20. State Clean Energy Policies Analysis (SCEPA): State Tax Incentives

    Energy Technology Data Exchange (ETDEWEB)

    Lantz, E.; Doris, E.

    2009-10-01

    As a policy tool, state tax incentives can be structured to help states meet clean energy goals. Policymakers often use state tax incentives in concert with state and federal policies to support renewable energy deployment or reduce market barriers. This analysis used case studies of four states to assess the contributions of state tax incentives to the development of renewable energy markets. State tax incentives that are appropriately paired with complementary state and federal policies generally provide viable mechanisms to support renewable energy deployment. However, challenges to successful implementation of state tax incentives include serving project owners with limited state tax liability, assessing appropriate incentive levels, and differentiating levels of incentives for technologies with different costs. Additionally, state tax incentives may result in moderately higher federal tax burdens. These challenges notwithstanding, state tax incentives that consider certain policy design characteristics can support renewable energy markets and state clean energy goals.The scale of their impact though is directly related to the degree to which they support the renewable energy markets for targeted sectors and technologies. This report highlights important policy design considerations for policymakers using state tax incentives to meet clean energy goals.

    1980-04-01

    During the 1970s a number of different exploration and production incentive programs were put in place in Canada, in particular in the Province of Alberta, Canada's principal oil- and gas-producing province. The DOE/RA is evaluating Canadian incentives for oil and gas exploration, and this study is intended to provide information that will help guide DOE/RA in determining the applicability of Canadian incentive programs in US energy policy. The study describes and documents the fiscal structure in which the Canadian oil industry operates. The incentive features of pricing policy, taxation policy, and provincial royalty systems are discussed. A principal focus of the study is on one of the most important of Canada's specific incentive programs, the Alberta Exploratory Drilling Incentive Credit Program (EDICP). The study describes and evaluates the effect of the EDICP on increased oil and gas exploration activity. Similarly, the study also reviews and evaluates other specific incentive programs such as the Alberta Geophysical Incentive Program, Frontier Exploration Allowances, and various tar sand and heavy oil development incentives. Finally the study evaluates the applicability of Canadian incentives to US energy policy.

    The CMS experiment collects and analyzes large amounts of data coming from high energy particle collisions produced by the Large Hadron Collider (LHC) at CERN. This involves a huge amount of real and simulated data processing that needs to be handled in batch-oriented platforms. The CMS Global Pool of computing resources provide +100K dedicated CPU cores and another 50K to 100K CPU cores from opportunistic resources for these kind of tasks and even though production and event processing analysis workflows are already managed by existing tools, there is still a lack of support to submit final stage condor-like analysis jobs familiar to Tier-3 or local Computing Facilities users into these distributed resources in an integrated (with other CMS services) and friendly way. CMS Connect is a set of computing tools and services designed to augment existing services in the CMS Physics community focusing on these kind of condor analysis jobs. It is based on the CI-Connect platform developed by the Open Science Grid and uses the CMS GlideInWMS infrastructure to transparently plug CMS global grid resources into a virtual pool accessed via a single submission machine.

    2012-07-01

    The overall objective of this project was to design and build a combined heat and power plant based on an updraft gasifier and a 35 kW electrical output Stirling engine and further to test the flexibility of the plant with regards to fuel and application. In the project a containerized combined heat and power plant including a 200 kW updraft gasifier and a 35 kW electrical output Stirling engine was designed, the specified components were procured, the plant was installed in the three containers and the plant was erected at Amagerforbraendingen ready for the COP15 in November 2009. The potential of operating the Stirling engine in island-mode (without grid connection) was investigated by mathematical modelling. Using an absorption cooling plant connected to the Stirling CHP plant was also investigated. A technical feasibility study was undertaken and it was concluded that from the two available technologies (water/LiBr and Ammonia/water) the appropriate choice is depending on the required cooling temperature. Test runs focussed on investigating the fuel flexibility of two different configurations of Stirling engine CHP plants were carried out - respectively the updraft gasifier plant (the containerized plant and the DTU plant) and the pyrolysis plant (the plant situated at Barritskov). In order to perform these test runs a stable operation is required. On both the containerized plant and the pyrolysis plant this proved to be more challenging than expected and therefore the number of fuels tested was limited to willow chips at the containerized plant and dry wood residues, wood pellets and straw pellets on the pyrolysis plant. For all tested fuels it was possible to operate the plants, however different issues mainly related to the quality of the fuels were encountered. And so it can be concluded that the quality of the fuel is critical for the operation of both the updraft gasifier plant and the pyrolysis plant.

    Full Text Available It can be found quite often in the literature that many well-known architects have employed either the golden rectangle or the Fibonacci rectangle in their works. On contrary, it is rare to find any specific reason for using them so often. Recently, Shekhawat (2015 proved that the golden rectangle and the Fibonacci rectangle are one of the best connected rectangular arrangements and this may be one of the reasons for their high presence in architectural designs. In this work we present an algorithm that generates n-4 best connected rectangular arrangements so that the proposed solutions can be further used by architects for their designs.

    In order to reduce the state deficit the French government plans to reduce the financial incentives in all sectors and particularly in the sector of renewable energies. The photovoltaic sector is the most hit with a tax credit rate dropping from 50% (in 2009) to 22.5% (in 2011). For the other renewable energy sectors the tax credit rate will be reduced by 10% in 2011. The French government wants the cost of the tax credit on the renewable energies to drop from 2.8*10 9 euros in 2009 to 2.0*10 9 euros in 2011. (A.C.)

The theoretical performance analysis is performed considering a six-phase wind energy generator system interconnected with the grid. Results based on a MATLAB/Simulink simulation environment are discussed and the most relevant characteristics of the proposed control technique are highlighted considering the total harmonic distortion and the mean squared error as a parameters of performance.

    2012-01-01

    Several European countries have reformed their labor market institutions. Incentive effects of unemployment benefits have been an important aspect of these reforms. We analyse this issue in a principal-agent model, higher level of unemployment benefits improves the workers' position in wage bargaining, leading to stronger effort incentives and higher output. However, it also reduces incentives for labor market participation. Accordingly, there is a trade-off. We analyze how changes in the eco...

    Cooperative relations, within and between firms, play important roles in business. How to produce such relations, however, is less well understood. Building on work in evolutionary biology we examine the conditions under which group based incentives result in better performance than individual based incentives. We find that when individual and group interests are not aligned, group incentive systems lead to both higher group and individual performance. Hybrid reward systems, with both group a...

  3. Approaches and incentives to implement integrated pest management that addresses regional and environmental issues.

    Brewer, Michael J; Goodell, Peter B

    2012-01-01

    Agricultural, environmental, and social and policy interests have influenced integrated pest management (IPM) from its inception. The first 50 years of IPM paid special attention to field-based management and market-driven decision making. Concurrently, IPM strategies became available that were best applied both within and beyond the bounds of individual fields and that also provided environmental benefits. This generated an incentives dilemma for farmers: selecting IPM activities for individual fields on the basis of market-based economics versus selecting IPM activities best applied regionally that have longer-term benefits, including environmental benefits, that accrue to the broader community as well as the farmer. Over the past several decades, public-supported incentives, such as financial incentives available to farmers from conservation programs for farms, have begun to be employed to encourage use of conservation techniques, including strategies with IPM relevance. Combining private investments with public support may effectively address the incentives dilemma when advanced IPM strategies are used regionally and provide public goods such as those benefiting resource conservation. This review focuses on adaptation of IPM to these broader issues, on transitions of IPM from primarily individual field-based decision making to coordinated community decision making, and on the form of partnerships needed to gain long-lasting regional and environmental benefits.

    2018-02-01

    Variability and Uncertainties caused by renewable energy sources have called for large amount of balancing services. Demand side resources (DSRs) can be a good alternative of traditional generating units to provide balancing service. In the areas where the electricity market has not been fully established, e.g., China, DSRs can help balance the power system with incentive-based demand response programs. However, there is a lack of information about the interruption cost of consumers in these areas, making it hard to determine the rational amount of capacity incentive and energy compensation for the participants of demand response programs. This paper proposes an algorithm to calculate the amount of capacity incentive and energy compensation for demand response programs when there lacks the information about interruption cost. Available statistical information of interruption cost in referenced areas is selected as the referenced data. Interruption cost of the targeted area is converted from the referenced area by product per electricity consumption. On this basis, capacity incentive and energy compensation are obtained to minimize the payment to consumers. Moreover, the loss of consumers is guaranteed to be covered by the revenue they earned from load serving entities.

  5. Financial incentives to promote renewable energy systems in European electricity markets: a survey

    International Nuclear Information System (INIS)

    Haas, R.; Huber, C.; Wohlgemuth, N.

    2001-01-01

    Renewable energy systems may contribute to sustainable development. Therefore, one of the challenges for energy policy is to ensure that renewable energy options have a fair opportunity to compete with other supply resources. This paper presents a survey on promotion mechanisms to enhance the market penetration of renewable energies in European electricity markets. Strategies include rebates and tax incentives, regulated rates, system benefit charges, bidding-oriented mechanisms and various types of green pricing programs. The paper concludes that efficient promotion mechanisms should focus on incentives per kWh generated rather than on rebates on the investment in generating capacity (kW), and that there is no one single program type which has the best application to the promotion of all renewable technologies. For example, enhanced buy-back rates work as a dissemination strategy for wind energy but they do not work for photovoltaics. (author)

    This report reviews recent DSM shareholder incentive designs and performance at 10 US utilities identifies opportunities for regulators to improve the design of DSM shareholder incentive mechanisms to increase the procurement of cost-effective DSM resources. We develop six recommendations: (1) apply shared-savings incentives to DSM resource programs; (2) use markup incentives for individual programs only when net benefits are difficult to measure, but are known to be positive; (3) set expected incentive payments based on covering a utility's open-quotes hidden costs,close quotes which include some transitional management and risk-adjusted opportunity costs; (4) use higher marginal incentives rates than are currently found in practice, but limit total incentive payments by adding a fixed charge; (5) mitigate risks to regulators and utilities by lowering marginal incentive rates at high and low performance levels; and (6) use an aggregate incentive mechanism for all DSM resource programs, with limited exceptions (e.g., information programs where markups are more appropriate)

    1982-08-01

    The importance of social and institutional issues in the siting of nuclear waste facilities has been recognized in recent years. Limited evidence from a survey of rural Wisconsin residents in 1980 indicates that incentives may help achieve the twin goals of increasing local support and decreasing local opposition to hosting nuclear waste facilities. Incentives are classified according to functional categories (i.e., mitigation, compensation, and reward) and the conditions which may be prerequisites to the use of incentives are outlined (i.e., guarantee of public health and safety, some measure of local control, and a legitimation of negotiations during siting). Criteria for evaluating the utility of incentives in nuclear waste repository siting are developed. Incentive packages may be more useful than single incentives, and nonmonetary incentives, such as independent monitoring and access to credible information, may be as important in eliciting support as monetary incentives. Without careful attention to prerequisites in the siting process it is not likely that incentives will facilitate the siting process.

    The success of any dental practice depends, among other factors, on the critical role of staff employees. In order to encourage desired staff behaviors, incentive systems can be designed for employee dentists, assistants/hygienists and managers. A survey of dental franchises was conducted in 1987 for the purpose of examining their incentive control systems. The specific incentives employed by these dental franchises for their employees are analyzed. The implications of these incentive systems used by dental franchise organizations for all dental practices are then discussed.

    Research has demonstrated that health outcomes are significantly improved with the application of financial incentives. However, relatively larger incentives are not typically sustainable and removal of incentives tends to result in attrition of behavior. The feasibility of using relatively smaller incentives to improve physical activity is unclear. The aim of the present study is to determine whether small financial incentives (maximum $5.00 per week) can improve exercise-related energy expenditure of inactive individuals. Twenty-two university students (20 ±1.6 years old) were randomized into incentive or non-incentive conditions. Exercise-related caloric expenditure was tracked over 10 weeks. The sample size yielded 62% power. The repeated measures ANCOVA, controlling for body mass index, indicated a main effect of condition (F = 5.50, p =.03) with no significant interaction (F = 2.25, p = .06). This pilot study demonstrates initial feasibility in implementing small financial incentives to promote exercise behavior in previously inactive young adults. Due to the small sample size, results should be interpreted with caution and further research is warranted to improve and maintain exercise behavior in response to relatively smaller incentives.

    Full Text Available In the era of constant connectivity, using the internet for personal purposes during working hours may become counterproductive. However, surfing for a few minutes could be stress reliever for employees. Therefore, the objective of this study is to analyze motivation of cyberloafers among Indonesian employees across generations. Data gathered from 313 respondents was analyzed using descriptive and chi-square analysis. Major findings of this study were that the three generations cyberloafed during office hours, but in different amounts of time and different motivation. Gen Y had a tendency to blend internet for task-personal purposes at work; whereas Gen X and Baby Boomers merely used the internet for task completion. Cyberloafing is not only the result of the employees being counterproductive, but also management failure in implementing internet policy and giving sanctions consistently. Hence, it is recommended that organizations should promote a culture of hard work by giving challenging targets with attractive incentives.

    Due to economic, environmental and technological incentives small and decentralized generators are becoming popular, which is changing the aspect of the electric power system. This new configuration brings up many issues related to the power quality, security and continuity of distribution. This paper proposes an overview and an analysis of some aspects of distributed generation and microgrids. The operation in interconnected and in islanding modes will be discussed, in particular alternation between the operation modes. Simulation results of a small system with three busses, modeled in MATLAB Simulink will be shown to point out some issues. The connection of the power sources to the grid as well as its control will be systematically reported. (author)

  16. Sustainable Groundwater Management Using Economic Incentive Approach

    Yan, T.; Shih, J.; Sanchirico, J. N.

    2006-12-01

    Although groundwater accounts for about 20% of the water consumption in the US, recent urban development, land use changes and agricultural activities in many regions (for example, Chesapeake Bay and eastern shore of Maryland) have resulted in deleterious impacts on groundwater quality. These impacts have dramatically increased potential human health and ecological system risks. One example is nitrogen pollution delivered to local waterways from septic systems via groundwater. Conventional approaches for nitrogen removal, such as pumping and treatment (nitrification-denitrification) process, tend to be expensive. On the other hand, economic incentive approaches (such as marketable permits) have the potential to increase the efficiency of environmental policy by reducing compliance costs for regulated entities and individuals and/or achieving otherwise uneconomical pollution reduction. The success of the sulfur dioxide trading market has led to the creation of trading markets for other pollutants, especially at the regional, state, and smaller (e.g. watershed) scales. In this paper, we develop an integrated framework, which includes a groundwater flow and transport model, and a conceptual management model. We apply this framework to a synthetic set up which includes one farm and two development areas in order to investigate the potential of using economic incentive approaches for groundwater quality management. The policy analysis is carried out by setting up the objective of the modeling framework to minimize the total cost of achieving groundwater quality goals at specific observation point using either a transferable development right (TDR) system between development areas and/or using a tax for fertilizer usage in the farm area. The TDR system consists of a planning agency delineating a region into restricted-use (e.g., agriculture, open space) and high intensity zones (e.g., residential, commercial uses). The agency then endows landowners in the restricted area

  17. A Credit-Based Congestion-Aware Incentive Scheme for DTNs

    Directory of Open Access Journals (Sweden)

    Qingfeng Jiang

    2016-12-01

    Full Text Available In Delay-Tolerant Networks (DTNs, nodes may be selfish and reluctant to expend their precious resources on forwarding messages for others. Therefore, an incentive scheme is necessary to motivate selfish nodes to cooperatively forward messages. However, the current incentive schemes mainly focus on encouraging nodes to participate in message forwarding, without considering the node congestion problem. When many messages are forwarded to the nodes with high connection degree, these nodes will become congested and deliberately discard messages, which will seriously degrade the routing performance and reduce the benefits of other nodes. To address this problem, we propose a credit-based congestion-aware incentive scheme (CBCAIS for DTNs. In CBCAIS, a check and punishment mechanism is proposed to prevent forwarding nodes from deliberately discarding message. In addition, a message acceptance selection mechanism is proposed to allow the nodes to decide whether to accept other messages, according to self congestion degree. The experimental results show that CBCAIS can effectively stimulate selfish nodes to cooperatively forward messages, and achieve a higher message delivery ratio with lower overhead ratio, compared with other schemes.

    Many people aim to change their lifestyle, but have trouble acting on their intentions. Behavioral economic incentives and related emotions can support commitment to personal health goals, but the related emotions remain unexplored. In a regret lottery, winners who do not attain their health goals do not get their prize but receive feedback on what their forgone earnings would have been. This counterfactual feedback should provoke anticipated regret and increase commitment to health goals. We explored which emotions were actually expected upon missing out on a prize due to unsuccessful weight loss and which incentive-characteristics influence their likelihood and intensity. Participants reported their expected emotional response after missing out on a prize in one of 12 randomly presented incentive-scenarios, which varied in incentive type, incentive size and deadline distance. Participants primarily reported feeling disappointment, followed by regret. Regret was expected most when losing a lottery prize (vs. a fixed incentive) and intensified with prize size. Multiple features of the participant and the lottery incentive increase the occurrence and intensity of regret. As such, our findings can be helpful in designing behavioral economic incentives that leverage emotions to support health behavior change.

  9. The Wisconsin experience with incentives for demand-side management

    Landgren, D.A.

    1990-01-01

    It has been noted that, within traditional regulatory frameworks for electric utilities, factors exist which discourage demand side management (DSM) and that there is a lack of positive incentives for DSM. Regulatory agencies should therefore make it possible for DSM measures to benefit from the same treatment as supply-side measures. The Wisconsin Public Service Commission (WPSC) has recognized this need and has adopted various measures accordingly. The need for efficiency incentives is described according to the particular experience of Wisconsin Electric concerning their recourse to a DSM incentive and according to new incentive models being tested in collaboration with other electricity suppliers in Wisconsin. The WPSC has concluded that the fact of considering the costs relating to DSM as expenses or capitalizing them within the rate base does not motivate the utility to promote DSM programs. The WPSC has thus decided to experiment with energy efficiency incentives in order to evaluate their eventual impact. The choice of the type of incentive had an objective of starting the process in an area where the lack of experience has created, from the regulatory point of view, a reticence on the part of utilities to engage in DSM programs. The WPSC has designed a variety of incentive models which have been adapted to each utility's own situation. Specific incentive programs developed for three Wisconsin utilities are reviewed

    Abstract Financial incentives for medication adherence in patients with psychotic disorders are controversial. It is not yet known whether fears expressed by clinicians are borne out in reality. We aimed to explore community mental health clinicians’ experiences of the consequences of giving patients with psychotic disorders a financial incentive to take their depot medication. We implemented descriptive and thematic analyses of semistructured interviews with the clinicians of patients assigned to receive incentives within a randomized controlled trial. Fifty-nine clinicians were interviewed with regard to the effect of the incentives on 73 of the 78 patients allocated to receive incentives in the trial. Most commonly, the clinicians reported benefits for clinical management including improved adherence, contact, patient monitoring, communication, and trust (n = 52). Positive effects on symptoms, insight, or social functioning were reported for some (n = 33). Less commonly, problems for patient management were reported (n = 19) such as monetarization of the therapeutic relationship or negative consequences for the patient (n = 15) such as increased drug and alcohol use. Where requests for increased money occurred, they were rapidly resolved. It seems that, in most cases, the clinicians found that using incentives led to benefits for patient management and for patient health. However, in 33% of cases, some adverse effects were reported. It remains unclear whether certain clinical characteristics are associated with increased risk for adverse effects of financial incentives. The likelihood of benefit versus the smaller risk for adverse effects should be weighed up when deciding whether to offer incentives to individual patients. PMID:25692797

    First, an overall picture is presented of the extension of the use of cogeneration by the Italian brick industry. The particular suitability and usefulness of this form of energy to the brick industry are pointed out. Then a look is given at the legal and financial incentives which have been built into the National Energy Plan to encourage on-site production by Italian industries. Finally, a review is made of initiatives made by SNAM (the Italian National Methane Distribution Society) to develop a favourable tariff structure for on-site power producers using methane as their energy source, as well as, of the Society's efforts to set up a cogeneration equipment consulting service which would provide advice on cogeneration plant design, operation and maintenance

    2016-01-01

    The aim of this study was to determine the effect of wellness program configurations and financial incentives on employee participation rate. We analyze a nationally representative survey on workplace wellness programs from 407 employers using cluster analysis and multivariable regression analysis. Employers who offer incentives and provide a comprehensive set of program offerings have higher participation rates. The effect of incentives differs by program configuration, with the strongest effect found for comprehensive and prevention-focused programs. Among intervention-focused programs, incentives are not associated with higher participation. Wellness programs can be grouped into distinct configurations, which have different workplace health focuses. Although monetary incentives can be effective in improving employee participation, the magnitude and significance of the effect is greater for some program configurations than others.

    Full Text Available The central purpose of this paper is to examine the incentive contract as an equilibrium phenomenon. We analyse a model of vertical differentiation in which we deal with the strategic role of the competitor’s decisions in a successive duopoly. Is it better for a processor to offer an incentive contract to an upstream producer or the spot market? We determine the equilibrium of a game in which the processors simultaneously decide whether to offer an incentive contract or to continue at the spot market to acquire their input. Our results show that under successive duopoly, offering an incentive contract constitutes the unique equilibrium solution, which highlights the incentive contract persistence.

    Deregulation in Ontario's utility market has created incentives for local utilities to add new services to attract and keep customers, knowing that in a competitive energy market, only those utilities which offer the best services will survive. London Hydro, which provides power to southwestern Ontario launched a private enterprise called LondonConnect Inc. The new enterprise offers high-speed digital services to area businesses. London Hydro made this unique move to take advantage of the fact that 20 per cent of businesses communicate electronically. London Hydro believes that in the next five years, that number will increase to 80 per cent. The Metropolitan Area Network (MAN) gives businesses greater connectivity to the Internet and web services. One of the network's capabilities is realtime video conferencing between hydro locations. MAN can also be used to create a secure and private virtual community-wide area network of computers and office machines. The advantages are numerous. For example, hospitals will be able to exchange information between remote sites at incredible speeds. MAN is made up of fiber-optic cables and electronic routers. LondonConnect is expecting to provide access throughout London by the fall of 1999. A dozen clients have already signed up for the service. Installation of the system will cost $1,000 with fixed monthly rates. The cost will vary depending on the level of service. The network will cost London Hydro $3 million, but it is expected to generate $2.5 million annually in its first two years. 3 figs

  12. Effects of government incentives on wind innovation in the United States

    International Nuclear Information System (INIS)

    Horner, Nathaniel; Azevedo, Inês; Hounshell, David

    2013-01-01

    In the United States, as elsewhere, state and federal governments have considered or implemented a range of policies to create more sustainable energy generation systems in response to concerns over climate change, security of fuel supply, and environmental impacts. These policies include both regulatory instruments such as renewable portfolio standards (RPSs) and market incentives such as tax credits. While these policies are primarily geared towards increasing renewable generation capacity, they can indirectly affect innovation in associated technologies through a ‘demand-pull’ dynamic. Other policies, such as public research and development (R and D) funding, directly incentivize innovation through ‘technology-push’ means. In this letter, we examine these effects on innovation in the United States wind energy industry. We estimate a set of econometric models relating a set of US federal and state policies to patenting activity in wind technologies over the period 1974–2009. We find that RPS policies have had significant positive effects on wind innovation, whereas tax-based incentives have not been particularly effective. We also find evidence that the effects of RPS incentives differ between states. Finally, we find that public R and D funding can be a significant driver of wind innovation, though its effect in the US has been modest. (letter)

  13. Tariff-based incentives for improving coal-power-plant efficiencies in India

    Improving the efficiency of coal-based power plants plays an important role in improving the performance of India's power sector. It allows for increased consumer benefits through cost reduction, while enhancing energy security and helping reduce local and global pollution through more efficient coal use. A focus on supply-side efficiency also complements other ongoing efforts on end-use efficiency. The recent restructuring of the Indian electricity sector offers an important route to improving power plant efficiency, through regulatory mechanisms that allow for an independent tariff setting process for bulk purchases of electricity from generators. Current tariffs based on normative benchmarks for performance norms are hobbled by information asymmetry (where regulators do not have access to detailed performance data). Hence, we propose a new incentive scheme that gets around the asymmetry problem by setting performance benchmarks based on actual efficiency data, rather than on a normative basis. The scheme provides direct tariff-based incentives for efficiency improvements, while benefiting consumers by reducing electricity costs in the long run. This proposal might also be useful for regulators in other countries to incorporate similar incentives for efficiency improvement in power generation. (author)

  14. Did accelerated depreciation result in lower generation efficiencies for wind plants in India: An empirical analysis

    India ranks fifth in wind energy installations in the world; with an installed wind capacity is 22 GW at the end of 2014. This has been made possible by a combination of federal financial incentives and state-level feed in tariffs. The federal policies are accelerated depreciation, which allows for higher depreciations in earlier years; and generation based incentive, which provides a premium for each unit of generation. Accelerated depreciation appears to be more effective from deployment and cost perspectives; whereas, generation based incentive is said to be more effective in incentivizing generation. In this paper, using multivariable linear regressions on a sample of approximately 40 wind plants, while controlling for wind regime and wind turbine technology, we investigate the incremental impact of generation based incentive compared to accelerated depreciation. We find that generation based incentive results in at least 3 percentage points higher plant load factors than accelerated depreciation. This indicates that, if higher generation is the goal of renewable policies, generation based incentive should be preferred to accelerated depreciation. This would be similar to the move from investment tax credit to production tax credit in the U.S. - Highlights: • We examine generation effectiveness of federal renewable policies in India. • We examine accelerated depreciation and generation based incentives. • We use a cross-sectional regression analysis on a sample of approx. 40 wind plants. • Generation based incentive results in 3 percentage points higher plant load factor.

    This report is intended to serve as a resource for policymakers who wish to learn more about establishing cost-based incentives. The report will identify key renewable energy cost modeling options, highlight the policy implications of choosing one approach over the other, and present recommendations on the optimal characteristics of a model to calculate rates for cost-based incentives, feed-in tariffs (FITs), or similar policies. These recommendations will be utilized in designing the Cost of Renewable Energy Spreadsheet Tool (CREST). Three CREST models will be publicly available and capable of analyzing the cost of energy associated with solar, wind, and geothermal electricity generators. The CREST models will be developed for use by state policymakers, regulators, utilities, developers, and other stakeholders to assist them in current and future rate-setting processes for both FIT and other renewable energy incentive payment structures and policy analyses.

    Full Text Available This study aimed to analyze the cost/benefit of tax incentives and performance indicators of Grendene S/A footwear company in the period of 2010 to 2014. The research is justified by the importance of companies seeking techniques and methodologies that are more advantageous corporately to achieve better performance. In this sense, the accounting is shown as an important tool, acting as a source of information for decision-making and wealth measurement of their investors. The methodology will be through case study in a company in the footwear sector, listed on the BM & FBovespa, with data in the periods of 2010 to 2014 available at the base of Economatica and the Financial Statements. Having the data has been identified, the modalities of tax incentives that the company benefited during the study, as well as the traditional performance indicators. To analyze the cost/benefit of tax incentives was used data from DVA and tax subsidies provided in the notes to DFPs. The results show that the company needs a constant and effective monitoring of the costs and benefits of tax waiver. Also identifies that the value of tax incentives received does not equal proportion the generation of net wealth. The results of this study confirm the theoretical basis that the benefits brought by tax incentives outnumber the costs of tax waiver, but may represent a dangerous dependence as to jeopardize the continuity of the company if they were removed.

    2002-06-01

    The desire of national policymakers to encourage entrepreneurial behavior in the health sector has generated not only a new structure of market-oriented incentives, but also a new regulatory role for the State. To ensure that entrepreneurial behavior will be directed toward achieving planned market objectives, the State must shift modalities from staid bureaucratic models of command-and-control to more sensitive and sophisticated systems of oversight and supervision. Available evidence suggests that this structural transformation is currently occurring in several Northern European countries. Successful implementation of that shift will require a new, intensive, and expensive strategy for human resources development, raising questions about the financial feasibility of this incentives-plus-regulation model for less-well-off CEE/CIS and developing countries.

    Intelligent Transportation Systems (ITSs) can be applied to inform and incentivize travellers to help them make cognizant choices concerning their trip routes and transport modality use for their daily travel whilst achieving more sustainable societal and transport authority goals. However, in practice, it is challenging for an ITS to enable incentive generation that is context-driven and personalized, whilst supporting multi-dimensional travel goals. This is because an ITS has to address the situation where different travellers have different travel preferences and constraints for route and modality, in the face of dynamically-varying traffic conditions. Furthermore, personalized incentive generation also needs to dynamically achieve different travel goals from multiple travellers, in the face of their conducts being a mix of both competitive and cooperative behaviours. To address this challenge, a Rule-based Incentive Framework (RIF) is proposed in this paper that utilizes both decision tree and evolutionary game theory to process travel information and intelligently generate personalized incentives for travellers. The travel information processed includes travellers’ mobile patterns, travellers’ modality preferences and route traffic volume information. A series of MATLAB simulations of RIF was undertaken to validate RIF to show that it is potentially an effective way to incentivize travellers to change travel routes and modalities as an essential smart city service.

    Title IV of the Clean Air Act Amendments of 1990 (P.L. 101-549) uses tradeable SO 2 allowances as a means of reducing acidic emissions from the electricity generating industry. The use of emission allowances generates two important results; first, utilities are given the flexibility to choose their optimal (least cost) compliance strategies and second, the use of emission allowances creates greater incentives for the development and commercialization of innovative emissions control technology. Clean Coal Technologies (CCTs) are able to generate electricity more efficiently, use a wide variety of coal grades and types, and dramatically reduce emissions of SO 2 , NO x , CO 2 , and PM per kWh. However, development and adoption of the technology is limited by a variety of regulatory and technological risks. The use of SO 2 emission allowances may be able to provide incentives for utility (and nonutility) adoption of this innovative technology. Emission allowances permit the utility to minimize costs on a systemwide basis and provides rewards for addition emission reductions. As CCTs are a more efficient and low emitting source of electricity, the development and implementation of this technology is desirable. This paper will explore the relationship between the incentives created by the SO 2 allowance market and CCT development. Regulatory hindrances and boons for the allowance market shall also be identified to analyze how market development, state mandates, and incentive regulation will effect the ability of allowances to prompt CCT adoption

    Highlights: • Tennessee solar value chain (TNSVC) is modeled to analyze effect of policy on demand. • TNSVC model replicates realistic scenarios to gauge the economic impact on state. • Simulation study determines that the TNSVC capacity is greater than demand. • Direct cash incentives have greater impact on demand than indirect incentives. • The model portrays a holistic approach to assist strategic energy policy analysis. - Abstract: The market for solar energy in the US has grown exponentially due to increased consumer demand resulting from price reduction via economies of scale, technological progress, and a variety of incentives from federal and state governments as well as utility companies. The installation of solar power in Tennessee has more than doubled each year from 2009 to 2011. In this paper, we focus on the behavior of the Tennessee Solar Value Chain (TNSVC) to study the factors that influence growth of solar industry in the state. The impact of existing incentives on the TNSVC is analyzed. The TNSVC is simulated based on inputs from on-site survey to estimate economic impact in terms of the number of jobs added and the tax revenue generated in the state. In addition, a sensitivity analysis for the impact on the TNSVC under different policies those may be adopted by the state of Tennessee in the future is conducted. This paper employs a holistic model which can predict PV installation demand, understand solar value chain capacity, and estimate the revenue generation. It should be noted that the method employed in this study is not unique to the solar energy industry in Tennessee. The data utilized in this study is a combination of public domain information and surveys of suppliers, manufacturers, distributors, and installers. This makes the model in this paper flexible enough to be applied to assess the solar value chain in other state or country

  2. Interpersonal Communication and Smoking Cessation in the Context of an Incentive-Based Program: Survey Evidence From a Telehealth Intervention in a Low-Income Population.

    The tobacco epidemic disproportionately affects low-income populations, and telehealth is an evidence-based strategy for extending tobacco cessation services to underserved populations. A public health priority is to establish incentive-based interventions at the population level in order to promote long-term smoking cessation in low-income populations. Yet randomized clinical trials show that financial incentives tend to encourage only short-term steps of cessation, not continuous smoking abstinence. One potential mechanism for increasing long-term cessation is interpersonal communication (IPC) in response to population-level interventions. However, more research is needed on IPC and its influence on health behavior change, particularly in the context of incentive-based, population-level programs. This study used survey data gathered after a population-level telehealth intervention that offered $20 incentives to low-income smokers for being connected to Minnesota's free quitline in order to examine how perceived incentive importance and IPC about the incentive-based program relate to both short-term and long-term health behavior change. Results showed that IPC was strongly associated with initial quitline utilization and continuous smoking abstinence as measured by 30-day point prevalence rates at 7-month follow-up. Perceived incentive importance had weak associations with both measures of cessation, and all associations were nonsignificant in models adjusting for IPC. These results were found in descriptive analyses, logistic regression models, and Heckman probit models that adjusted for participant recruitment. In sum, a behavioral telehealth intervention targeting low-income smokers that offered a financial incentive inspired IPC, and this social response was strongly related to utilization of intervention services as well as continuous smoking abstinence.

    Managed care organizations use explicit financial incentives to influence physicians' use of resources. This has contributed to concerns regarding conflicts of interest for physicians and adverse effects on the quality of patient care. In light of recent publicized legislative and legal battles about this issue, we reviewed the literature and analyzed studies that examine the effect of these explicit financial incentives on the behavior of physicians. The method used to undertake the literature review followed the approach set forth in the Cochrane Collaboration handbook. Our literature review revealed a paucity of data on the effect of explicit financial incentives. Based on this limited evidence, explicit incentives that place individual physicians at financial risk appear to be effective in reducing physician resource use. However, the empirical evidence regarding the effectiveness of bonus payments on physician resource use is mixed. Similarly, our review revealed mixed effects of the influence of explicit financial incentives on the quality of patient care. The effect of explicit financial incentives on physician behavior is complicated by a lack of understanding of the incentive structure by the managed care organization and the physician. The lack of a universally acceptable definition of quality renders it important that future researchers identify the term explicitly.

    Reducing costs and increasing benefits for rural communities coexisting with large carnivores is necessary for conservation of jaguar (Panthera onca) and puma (Puma concolor). To design acceptable incentives, stakeholders must be involved in the process. We conducted an innovative, structured, group communication process based on a Delphi technique as a template for identifying potential incentives. Community workshops with 133 members of 7 communities and surveys with 25 multidisciplinary experts from government, nongovernmental organizations, and academia provided iterative data to design a plan of incentives through 4 rounds of discussion. The final product integrated 862 ideas into 6 types of incentives: organization of communities, mechanisms for improved dialogue, citizen technical assistance, green labeling for community products, payment for the ecosystem service of biodiversity, and an assessment of financial alternatives. We used quantitative and qualitative techniques to indicate support for decisions about the design of incentives, which reduced researcher subjectivity. The diverse incentives developed and the cooperation from multiple stakeholders resulted in an incentive plan that integrated issues of governance, equity, and social norms. © 2018 Society for Conservation Biology.

    This paper (1) estimates the total costs of federal expenditures in support of incentives for the development of commercial nuclear energy through 1988, and (2) analyzes the results and benefits to the nation of this federal investment. The federal incentives analyzed include research and development, regulation of commercial nuclear energy, tax incentives, waste management and disposal, enrichment plants, liability insurance, the uranium mining industry, and all other federal support activities. The authors estimate that net federal incentives totaled about $45-50 billion (1988 dollars). They estimate the results of the federal incentives, focusing on six categories, namely, electric energy produced, the total (direct plus indirect) economic benefits of the industry created, R and D program benefits, value of energy imports displaced, environmental effects, and health, safety, and risk effects. The results total $1.9 trillion, with approximately $250-300 billion identified as net benefits. The authors conclude that the high return on the investment justified federal incentives for nuclear energy development over the past four decades and that the federal government and the nation have received a significant return on the incentives investment

    The deployment of solar photovoltaic (PV) systems has grown rapidly over the last decade, partly because of various government incentives. In the United States, among the largest and longest-running incentives have been those established in California. Building on past research, this report addresses the still-unanswered question: to what degree have the direct PV incentives in California been passed through from installers to consumers? This report helps address this question by carefully examining the residential PV market in California (excluding a certain class of third-party-owned PV systems) and applying both a structural-modeling approach and a reduced-form regression analysis to estimate the incentive pass-through rate. The results suggest an average pass-through rate of direct incentives of nearly 100%, though with regional differences among California counties. While these results could have multiple explanations, they suggest a relatively competitive market and well-functioning subsidy program. Further analysis is required to determine whether similar results broadly apply to other states, to other customer segments, to all third-party-owned PV systems, or to all forms of financial incentives for solar (considering not only direct state subsidies, but also utility electric bill savings and federal tax incentives).

    The Western Business Unit Bakersfield drilling department of Chevron, U.S.A. Production Company developed a drilling performance incentive contract that was implemented during 1994 in the Lost Hills field of California. The performance incentive contract (PIC) financially rewarded all of the drilling contractor's rig employees for outperforming pre-established drilling performance goals. The key elements of the performance incentive program are: (1) Goals that rigger incentives are based on cost categories that are controllable by the drilling team; (2) Goals were established using a database of past years performance; (3) Goals that are not achieved negatively impact the incentive earned in an effort to deter repeated errors; (4) Accidents that occur on the job negatively impact the incentive earned; (5) Administration of the program is not time consuming. The results of using an incentive contract in the Lost Hills drilling program are: (1) Time and cost of operations are reduced; (2) The results are measurable and repeatable; (3) A team environment develops in which ideas are shared and acted upon by crew members and supervisory personnel

    A variety of reforms to traditional approaches to provider payment and benefit design are being implemented in the United States. There is increasing interest in applying these financial incentives to orthopaedics, although it is unclear whether and to what extent they have been implemented and whether they increase quality or reduce costs. We reviewed and discussed physician- and patient-oriented financial incentives being implemented in orthopaedics, key challenges, and prerequisites to payment reform and value-driven payment policy in orthopaedics. We searched the MEDLINE database using as search terms various provider payment and consumer incentive models. We retrieved a total of 169 articles; none of these studies met the inclusion criteria. For incentive models known to the authors to be in use in orthopaedics but for which no peer-reviewed literature was found, we searched Google for further information. Provider financial incentives reviewed include payments for reporting, performance, and patient safety and episode payment. Patient incentives include tiered networks, value-based benefit design, reference pricing, and value-based purchasing. Reform of financial incentives for orthopaedic surgery is challenged by (1) lack of a payment/incentive model that has demonstrated reductions in cost trends and (2) the complex interrelation of current pay schemes in today's fragmented environment. Prerequisites to reform include (1) a reliable and complete data infrastructure; (2) new business structures to support cost sharing; and (3) a retooling of patient expectations. There is insufficient literature reporting the effects of various financial incentive models under implementation in orthopaedics to know whether they increase quality or reduce costs. National concerns about cost will continue to drive experimentation, and all anticipated innovations will require improved collaboration and data collection and reporting.

    Full Text Available Objective. To evaluate the effects of diaphragmatic breathing exercises and flow and volume-oriented incentive spirometry on pulmonary function and diaphragm excursion in patients undergoing laparoscopic abdominal surgery. Methodology. We selected 260 patients posted for laparoscopic abdominal surgery and they were block randomization as follows: 65 patients performed diaphragmatic breathing exercises, 65 patients performed flow incentive spirometry, 65 patients performed volume incentive spirometry, and 65 patients participated as a control group. All of them underwent evaluation of pulmonary function with measurement of Forced Vital Capacity (FVC, Forced Expiratory Volume in the first second (FEV1, Peak Expiratory Flow Rate (PEFR, and diaphragm excursion measurement by ultrasonography before the operation and on the first and second postoperative days. With the level of significance set at p<0.05. Results. Pulmonary function and diaphragm excursion showed a significant decrease on the first postoperative day in all four groups (p<0.001 but was evident more in the control group than in the experimental groups. On the second postoperative day pulmonary function (Forced Vital Capacity and diaphragm excursion were found to be better preserved in volume incentive spirometry and diaphragmatic breathing exercise group than in the flow incentive spirometry group and the control group. Pulmonary function (Forced Vital Capacity and diaphragm excursion showed statistically significant differences between volume incentive spirometry and diaphragmatic breathing exercise group (p<0.05 as compared to that flow incentive spirometry group and the control group. Conclusion. Volume incentive spirometry and diaphragmatic breathing exercise can be recommended as an intervention for all patients pre- and postoperatively, over flow-oriented incentive spirometry for the generation and sustenance of pulmonary function and diaphragm excursion in the management of

    Employers seeking to motivate and encourage healthy behaviors among their employees are increasingly turning to incentive rewards. In fact, a recent Buck Consultants survey of 555 employers, titled Working Well: A Global Survey of Health Promotion and Workplace Wellness Strategies, predicts the use of such rewards to more than double over the next two to three years. This article provides an overview of the key considerations for employers seeking to maximize the value of incentive rewards. Discussion includes incentive strategies, types of rewards, reward amounts and regulatory considerations under the Health Insurance Portability and Accountability Act (HIPAA) and the Americans with Disabilities Act (ADA).

    We consider an environment where self-interested IEEE 802.11 Wireless Local Area Networks (WLANs) have overlapping coverage, and investigate the incentives that can trigger handovers between the WLANs. Our focus is on the incentives for supporting handovers due solely to the improved performance...... for all wireless networks. Such incentives arise due to a well-known property of 802.11 networks, where low rate users that send traffic significantly degrade the performance of high rate users that are associated with the same access point.

    2014-01-01

    Full Text Available Overhead transmission line icing is one of the main factors affecting safety and reliability of power grid. This paper proposed an excitation deicing method of iced wire and theoretically revealed the ice removal mechanism under displacement excitation conditions, by taking the LGJ-70/10 glaze icing wire as the 3D model and analyzing and studying its dynamic response under the effect of displacement excitation. The simulation results show that the stress of wire icing area is enlarged with the increase of excitation displacement and frequency. Through the comparison of the compression strength experimental results on a series of different iced wires in low temperature environment, the authors found out that the stress generated from the wire icing area is greater than the crushing strength of the ice within the scope of the calculation parameters, which proved the validity and the feasibility of the method, and finally the suitable excitation displacement is determined. Following studies show that, as far as possible, it is necessary to reduce the incentive displacement and also to select the appropriate constraint length in order to avoid the line jumping that may be caused by large span ice shedding.

  15. STATE BENEFIT - INCENTIVE FOR SAVINGS AND INVESTMENTS

    2015-12-01

    Full Text Available The present paper aims to be an answer for many investors with financial powers, seeking financial instruments with yields above the average interest rate on the banking market. One such tool, fairly new to the Romanian banking market, has been implemented for about 14 years, and is becoming more and more an instrument for savings, investments or an aid in the purchase of a house. Regardless of the perspective presented in the table of contents, the incentive for choosing such a banking product is the state benefit, a form through which the administration creates the conditions necessary to update and develop the housing system. In the thesis I have explored aspects of legislation which, in such a short period of time have changed 3 times the amount and the method of granting the state benefit and I have also tried a quick historical and legislative evolution of the implementation of Bauspar system throughout Europe. It is pointed out that in comparison with other countries - namely Germany, England or Austria where this system is well-known and has been implemented for over 120 years - Romania is at the beginning of its journey, a fact proved especially by the number of signed contracts in relation to the number of inhabitants.

  16. Economic incentives and foster child adoption.

    2013-06-01

    Every year, a large number of children in the United States enter the foster care system. Many of them are eventually reunited with their biological parents or quickly adopted. A significant number, however, face long-term foster care, and some of these children are eventually adopted by their foster parents. The decision by foster parents to adopt their foster child carries significant economic consequences, including for feiting foster care payments while also assuming responsibility for medical, legal, and educational expenses, to name a few. Since 1980, U.S. states have begun to offer adoption subsidies to offset some of these expenses, significantly lowering the cost of adopting a child who is in the foster care system. This article presents empirical evidence of the role that these economic incentives play in foster parents' decision of when, or if, to adopt their foster child. We find that adoption subsidies increase adoptions through two distinct price mechanisms: by lowering the absolute cost of adoption, and by lowering the relative cost of adoption versus long-term foster care.

  17. How unconventional gas prospers without tax incentives

    1995-01-01

    It was widely believed that the development of unconventional natural gas (coalbed methane, gas shales, and tight gas) would die once US Sec. 29 credits stopped. Quieter voices countered, and hoped, that technology advances would keep these large but difficult to produce gas resources alive and maybe even healthy. Sec. 29 tax credits for new unconventional gas development stopped at the end of 1992. Now, nearly three years later, who was right and what has happened? There is no doubt that Sec. 29 tax credits stimulated the development of coalbed methane, gas shales, and tight gas. What is less known is that the tax credits helped spawn and push into use an entire new set of exploration, completion, and production technologies founded on improved understanding of unconventional gas reservoirs. As set forth below, while the incentives inherent in Sec. 29 provided the spark, it has been the base of science and technology that has maintained the vitality of these gas sources. The paper discusses the current status; resource development; technology; unusual production, proven reserves, and well completions if coalbed methane, gas shales, and tight gas; and international aspects

    Full Text Available Stephen Gillam Department of Public Health and Primary Care, Institute of Public Health, University of Cambridge, Cambridge, UK Abstract: Pay-for-performance (P4P schemes have become increasingly common in primary care, and this article reviews their impact. It is based primarily on existing systematic reviews. The evidence suggests that P4P schemes can change health professionals' behavior and improve recorded disease management of those clinical processes that are incentivized. P4P may narrow inequalities in performance comparing deprived with nondeprived areas. However, such schemes have unintended consequences. Whether P4P improves the patient experience, the outcomes of care or population health is less clear. These practical uncertainties mirror the ethical concerns of many clinicians that a reductionist approach to managing markers of chronic disease runs counter to the humanitarian values of family practice. The variation in P4P schemes between countries reflects different historical and organizational contexts. With so much uncertainty regarding the effects of P4P, policy makers are well advised to proceed carefully with the implementation of such schemes until and unless clearer evidence for their cost–benefit emerges.

  19. Hybrid carbon incentive mechanisms and political acceptability

    Vollebergh, H.R.J.; De Vries, J.L.; Koutstaal, P.R.

    1997-01-01

    In this paper it is analyzed how hybrid systems of carbon taxes and tradeable permits optimize some conflicting dimensions of political acceptability related to the design of these instruments. Pure systems like taxes without exemptions or auctioned tradeable permits cause problems for political acceptability in open economies due to high overall costs (abatement cost plus payments on the tax or auctions) for current polluters. Unfortunately, pure systems based on grandfathering of emission rights across the board do not provide a feasible alternative because of monitoring and enforcement problems. In contrast, consciously designed hybrid systems employ grandfathering of emission rights together with either carbon taxes or auctioned carbon permits in order to overcome acceptability problems of pure systems, while leaving incentives to reduce emissions at the margin untouched. Moreover, monitoring and enforcement costs of the hybrid systems are less due to the lower number of participating agents compared with the pure systems, while opportunities for cost- or burden-sharing exist as well. 3 figs., 4 tabs., 23 refs

    Cross-reactivity of T cells is defined as recognition of two or more peptide-MHC complexes by the same T cell. Although examples of cross-reactivity have been reported, a detailed examination of cross-reactivity has not been performed. In this study, we took advantage of the high degree of polyclonality in the BV19 T cell repertoire responding to influenza M1(58-66) in HLA-A2 individuals to obtain a measure of simple cross-reactivity. We used substitutions that incrementally change the structure of the M1(58-66) peptide to measure how the HLA-A2-restricted response adapts to these changes. In three HLA-A2 adult subjects, we identified the BV19 clonotypes in the recall response to the influenza epitope M1(58-66) and 12 M1 peptides substituted at TCR contact position 63 or 65. The fraction of cross-reactive clonotypes in the M1(58-66) repertoire varied from 45-58% in the three donors. The extent of cross-reactivity, which is the additional number of peptides recognized by a single clonotype, is as high as six. We summarized the data using graph theory, with the cross-reactive clonotypes connecting the different HLA-A2 peptides recognized. The cross-reactive clonotypes form a well-connected network that could provide protection from virus-escape variants. We predict that any new pathogen with an epitope whose shape corresponds to that of the peptides that we studied would find a pre-existing repertoire ready to respond to it. We propose that in adult memory repertoires, previously encountered epitopes may have generated similar cross-reactive repertoires.

  1. On the Action of the Radiation Field Generated by a Traveling-Wave Element and Its Connection to the Time Energy Uncertainty Principle, Elementary Charge and the Fine Structure Constant

    Directory of Open Access Journals (Sweden)

    Vernon Cooray

    2017-02-01

    Full Text Available Recently, we published two papers in this journal. One of the papers dealt with the action of the radiation fields generated by a traveling-wave element and the other dealt with the momentum transferred by the same radiation fields and their connection to the time energy uncertainty principle. The traveling-wave element is defined as a conductor through which a current pulse propagates with the speed of light in free space from one end of the conductor to the other without attenuation. The goal of this letter is to combine the information provided in these two papers together and make conclusive statements concerning the connection between the energy dissipated by the radiation fields, the time energy uncertainty principle and the elementary charge. As we will show here, the results presented in these two papers, when combined together, show that the time energy uncertainty principle can be applied to the classical radiation emitted by a traveling-wave element and it results in the prediction that the smallest charge associated with the current that can be detected using radiated energy as a vehicle is on the order of the elementary charge. Based on the results, an expression for the fine structure constant is obtained. This is the first time that an order of magnitude estimation of the elementary charge based on electromagnetic radiation fields is obtained. Even though the results obtained in this paper have to be considered as order of magnitude estimations, a strict interpretation of the derived equations shows that the fine structure constant or the elementary charge may change as the size or the age of the universe increases.

    We explored current policies and practices on the use of incentives in research involving adult offenders under correctional supervision in prison and in the community (probation and parole) in Canada. We contacted the correctional departments of each of the Canadian provinces and territories, as well as the federal government department responsible for offenders serving sentences of two years or more. Findings indicated that two departments had formal policy whereas others had unwritten practices, some prohibiting their use and others allowing incentives on a case-by-case basis. Given the differences across jurisdictions, it would be valuable to examine how current incentive policies and practices are implemented to inform national best practices on incentives for offender-based research.

    Lunze, Karsten; Paasche-Orlow, Michael K

    2013-06-01

    Economic incentives to promote healthy behavior are becoming increasingly common and have been suggested as an approach to decreasing healthcare costs. Ethical concerns about programs with such incentives are that they may contribute to inequities, be coercive, interfere with therapeutic relationships, undermine personal responsibility for health, and decrease social solidarity. Additionally, they may be a source of stigma or discrimination, promote dependence, and be unfair for those already engaged in targeted health behaviors or those who cannot fulfill the incentivized behaviors. Incentive programs need to incorporate appropriate safeguards to monitor these risks and support fairness in offering economic incentives to promote healthy behavior.

    Investment decisions are inherently forward-looking. The payoff of acquiring capital goods, particularly long-lived capital goods, is governed almost exclusively by events in the far future. Because the timing of the investment itself does not affect future payoffs, there are strong incentives to delay or accelerate investment to take advantage of predictable intertemporal variations in cost. For sufficiently long-lived capital goods, these incentives are so strong that the intertemporal elas...

  12. Incentive Mechanism of Micro-grid Project Development

    Directory of Open Access Journals (Sweden)

    Yong Long

    2018-01-01

    Full Text Available Due to the issue of cost and benefit, the investment demand and consumption demand of micro-grids are insufficient in the early stages, which makes all parties lack motivation to participate in the development of micro-grid projects and leads to the slow development of micro-grids. In order to promote the development of micro-grids, the corresponding incentive mechanism should be designed to motivate the development of micro-grid projects. Therefore, this paper builds a multi-stage incentive model of micro-grid project development involving government, grid corporation, energy supplier, equipment supplier, and the user in order to study the incentive problems of micro-grid project development. Through the solution and analysis of the model, this paper deduces the optimal subsidy of government and the optimal cooperation incentive of the energy supplier, and calculates the optimal pricing strategy of grid corporation and the energy supplier, and analyzes the influence of relevant factors on optimal subsidy and incentive. The study reveals that the cost and social benefit of micro-grid development have a positive impact on micro-grid subsidy, technical level and equipment quality of equipment supplier as well as the fact that government subsidies positively adjust the level of cooperation incentives and price incentives. In the end, the validity of the model is verified by numerical analysis, and the incentive strategy of each participant is analyzed. The research of this paper is of great significance to encourage project development of micro-grids and to promote the sustainable development of micro-grids.

  13. Short-term incentive schemes for hospital managers

    Directory of Open Access Journals (Sweden)

    Lucas Malambe

    2013-10-01

    Full Text Available Orientation: Short-term incentives, considered to be an extrinsic motivation, are commonly used to motivate performance. This study explored hospital managers’ perceptions of short term incentives in maximising performance and retention. Research purpose: The study explored the experiences, views and perceptions of private hospital managers in South Africa regarding the use of short-term incentives to maximise performance and retention, as well as the applicability of the findings to public hospitals. Motivation for the study: Whilst there is an established link between performance reward schemes and organisational performance, there is little understanding of the effects of short term incentives on the performance and retention of hospital managers within the South African context. Research design, approach, and method: The study used a qualitative research design: interviews were conducted with a purposive sample of 19 hospital managers, and a thematic content analysis was performed. Main findings: Short-term incentives may not be the primary motivator for hospital managers, but they do play a critical role in sustaining motivation. Participants indicated that these schemes could also be applicable to public hospitals. Practical/managerial implications: Hospital managers are inclined to be more motivated by intrinsic than extrinsic factors. However, hospital managers (as middle managers also seem to be motivated by short-term incentives. A combination of intrinsic and extrinsic motivators should thus be used to maximise performance and retention. Contribution/value-add: Whilst the study sought to explore hospital managers’ perceptions of short-term incentives, it also found that an adequate balance between internal and external motivators is key to implementing an effective short-term incentive scheme.

    Full Text Available The contributions of Distributed Energy Generation (DEG and Distributed Energy Storage (DES for Demand Side Management (DSM purposes in a smart macrogrid or microgrid cannot be over-emphasised. However, standalone DEG and DES can lead to under-utilisation of energy generation by consumers and financial investments; in grid-connection mode, though, DEG and DES can offer arbitrage opportunities for consumers and utility provider(s. A grid-connected smart microgrid comprising heterogeneous (active and passive smart consumers, electric vehicles and a large-scale centralised energy storage is considered in this paper. Efficient energy management by each smart entity is carried out by the proposed Microgrid Energy Management Distributed Optimisation Algorithm (MEM-DOA installed distributively within the network according to consumer type. Each smart consumer optimises its energy consumption and trading for comfort (demand satisfaction and profit. The proposed model was observed to yield better consumer satisfaction, higher financial savings, and reduced Peak-to-Average-Ratio (PAR demand on the utility grid. Other associated benefits of the model include reduced investment on peaker plants, grid reliability and environmental benefits. The MEM-DOA also offered participating smart consumers energy and tariff incentives so that passive smart consumers do not benefit more than active smart consumers, as was the case with some previous energy management algorithms.

  18. Analysis of Federal incentives used to stimulate energy production

    Energy Technology Data Exchange (ETDEWEB)

    1978-06-01

    Federal incentives for the development of solar energy are examined. A Federal incentive is any action that can be taken by the government to expand residential and commercial use of solar energy. The development of solar energy policy could be enhanced by identification, quantification, and analysis of Federal incentives that have been used to simulate the development of other forms of energy. The text of this report identifies, quantifies, and analyzes such incentives and relates them to current thought about solar energy. Four viewpoints used in this discussion come from 4 types of analysis: economic, political, organizational, and legal. The next chapter identifies actions (primarily domestic) that the Federal government has taken concerning energy. This analysis uses the typology of actions described in the previous chapter to identify actions, and the four viewpoints described there to determine whether an action concerns energy. Once identified, the actions are described and then quantified by an estimate of the 1976 cost of accomplishing them. Then incentives, investments, liabilities, regulations, and other factors are analyzed in detail for nuclear energy, hydroelectric power, coal, petroleum, and natural gas. Incentives of all energy sources are then discussed with respect to solar energy policy. (MCW)

  19. Neural effects of positive and negative incentives during marijuana withdrawal.

    Directory of Open Access Journals (Sweden)

    Francesca M Filbey

    Full Text Available In spite of evidence suggesting two possible mechanisms related to drug-seeking behavior, namely reward-seeking and harm avoidance, much of the addiction literature has focused largely on positive incentivization mechanisms associated with addiction. In this study, we examined the contributing neural mechanisms of avoidance of an aversive state to drug-seeking behavior during marijuana withdrawal. To that end, marijuana users were scanned while performing the monetary incentive delay task in order to assess positive and negative incentive processes. The results showed a group x incentive interaction, such that marijuana users had greater response in areas that underlie reward processes during positive incentives while controls showed greater response in the same areas, but to negative incentives. Furthermore, a negative correlation between withdrawal symptoms and response in the amygdala during negative incentives was found in the marijuana users. These findings suggest that although marijuana users have greater reward sensitivity and less harm avoidance than controls, that attenuated amygdala response, an area that underlies fear and avoidance, was present in marijuana users with greater marijuana withdrawal symptoms. This is concordant with models of drug addiction that involve multiple sources of reinforcement in substance use disorders, and suggests the importance of strategies that focus on respective mechanisms.

    To examine the effects of an employer-based monetary incentive program on membership termination and usage at a fitness center. Retrospective nested case-control study examining the relationship between participation in an incentive program, visits to the fitness center, and membership termination at 1 year. University-based fitness center. Members (N = 1122) of a university-based fitness center. Members were offered either a US$25 incentive for each month they visited the fitness center at least 10 times or no incentive. Data were extracted from the membership database and included membership termination at 1 year (yes, no), length of membership (days), participation in the incentive program (yes, no), and visits to the fitness center per month. Cox proportional hazards model. Members in the incentive program visited the fitness center on average more times per month (5.3 vs 4.3; P fitness center may be initially associated with a greater fitness center utilization but may not be associated with a reduced risk of membership termination.

    In many quarters, traditional cost-plus regulation has come to be perceived as a failure. This perception is, in part, the result of a conjunction of events, changing philosophy, and measurable performance problems in the electric utility industry. Risk, competition and prudence issues will dominate the regulatory agenda in the 1990s. The experience being gained through application of alternative regulation in the telecommunications industry will have a significant impact on the willingness of regulators to experiment with new incentive approaches in the electric and natural gas industries. If the goals of a program are well specified, and if the incentive mechanism is designed in the appropriate fashion, incentives can play a major role in least-cost planning programs and in more accommodating regulatory environments. Significant attention has been given to alternative incentive programs in the electric power industry. The purpose of this paper is not to review the extensive literature on incentives, but rather to provide a nuts and bolts, common-sense analysis of the strategic value of incentive mechanisms as a regulatory policy. 14 refs., 1 fig., 2 tabs.

  2. Ethics in human subjects research: do incentives matter?

    There is considerable confusion regarding the ethical appropriateness of using incentives in research with human subjects. Previous work on determining whether incentives are unethical considers them as a form of undue influence or coercive offer. We understand the ethical issue of undue influence as an issue, not of coercion, but of corruption of judgment. By doing so we find that, for the most part, the use of incentives to recruit and retain research subjects is innocuous. But there are some instances where it is not. Specifically, incentives become problematic when conjoined with the following factors, singly or in combination with one another: where the subject is in a dependency relationship with the researcher, where the risks are particularly high, where the research is degrading, where the participant will only consent if the incentive is relatively large because the participant's aversion to the study is strong, and where the aversion is a principled one. The factors we have identified and the kinds of judgments they require differ substantially from those considered crucial in most previous discussions of the ethics of employing incentives in research with human subjects.

    The Nuclear Regulatory Commission (NRC) monitors incentive programs established by state regulators in order to obtain current information and to consider the potential safety effects of the incentive programs as applied to nuclear units. The current report is an update of NUREG/CR-5509, Incentive Regulation of Nuclear Power Plants by State Public Utility Commissions, published in December 1989. The information in this report was obtained from interviews conducted with each state regulator and each utility with a minimum entitlement of 10%. The agreements, orders, and settlements from which each incentive program was implemented were reviewed as required. The interviews and supporting documentation form the basis for the individual state reports describing the structure and financial impact of each incentive program. The programs currently in effect represent the adoption of an existing nuclear performance incentive program proposal and one new program. In addition, since 1989 a number of nuclear units have been included in one existing program; while one program was discontinued and another one concluded. 6 refs., 27 tabs

    With increasing urban, industrial, and agricultural water demand and projected reduced supply under climate change, allocations to the environment are critically low in many arid and semiarid basins. Consequently, many governments are striving to augment environmental flows, often through market-oriented mechanisms that involve compensating irrigated agriculture, the largest water user in most basins, for reducing diversions. A widely documented challenge with policies to recover water for the environment arises because part of the water diversion reduction can form the basis for downstream consumptive water rights or environmental flows. This article gives an empirical comparison of two incentive policies to acquire water for environmental flows for a part of the Murray-Darling Basin (MDB), Australia. One policy consists of paying irrigators and water delivery firms to make capital and management investments that improve on-farm irrigation and water-conveyance; the other policy consists of having the government buy water from irrigators on the active MDB water market. The results show that the first option results in relatively larger return flow reduction, while the second option tends to induce significant irrigated land retirement with relatively large reductions in consumptive use and small reductions in return flow. In cases where irrigation losses result in little useful return flow (e.g., evaporative loss reduction or during drought in some instances), efficiency-improving investments may provide some cost-effective opportunities. Where a large portion of loss forms valuable return flow, it is difficult to make a case for the cost-effectiveness of policies involving payments for investments in irrigation and conveyance system upgrades.

    Conclusion: The results of this study proved that the surprising incentive would improve the employees' safety performance just in the short term because the surprising value of the incentives dwindle over time. For this reason and to maintain the surprising value of the incentive system, the amount and types of incentives need to be evaluated and modified annually or biannually.

    Full Text Available Abstract Background Sending a monetary incentive with postal questionnaires has been found to improve the proportion of responders, in research in non-healthcare settings. However, there is little research on use of incentives to improve follow-up rates in clinical trials, and existing studies are inconclusive. We conducted a randomised trial among participants in the Managing Injuries of the Neck Trial (MINT to investigate the effects on the proportion of questionnaires returned and overall non-response of sending a £5 gift voucher with a follow-up questionnaire. Methods Participants in MINT were randomised to receive either: (a a £5 gift voucher (incentive group or (b no gift voucher (no incentive group, with their 4 month or 8 month follow-up questionnaire. We recorded, for each group, the number of questionnaires returned, the number returned without any chasing from the study office, the overall number of non-responders (after all chasing efforts by the study office, and the costs of following up each group. Results 2144 participants were randomised, 1070 to the incentive group and 1074 to the no incentive group. The proportion of questionnaires returned (RR 1.10 (95% CI 1.05, 1.16 and the proportion returned without chasing (RR 1.14 (95% CI 1.05, 1.24 were higher in the incentive group, and the overall non-response rate was lower (RR 0.68 (95% CI 0.53, 0.87. Adjustment for injury severity and hospital of recruitment to MINT made no difference to these results, and there were no differences in results between the 4-month and 8-month follow up questionnaires. Analysis of costs suggested a cost of £67.29 per additional questionnaire returned. Conclusion Monetary incentives may be an effective way to increase the proportion of postal questionnaires returned and minimise loss to follow-up in clinical trials.

    Projection of current trends in maternal and neonatal mortality reduction shows that many countries will fall short of the UN Millennium Development Goal 4 and 5. Underutilization of maternal health services contributes to this poor progress toward reducing maternal and neonatal morbidity and mortality. Moreover, the quality of services continues to lag in many countries, with a negative effect on the health of women and their babies, including deterring women from seeking care. To enhance the use and provision of quality maternal care, countries and donors are increasingly using financial incentives. This paper introduces the JHPN Supplement, in which each paper reviews the evidence of the effectiveness of a specific financial incentive instrument with the aim of improving the use and quality of maternal healthcare and impact. The US Agency for International Development and the US National Institutes of Health convened a US Government Evidence Summit on Enhancing Provision and Use of Maternal Health Services through Financial Incentives on 24-25 April 2012 in Washington, DC. The Summit brought together leading global experts in finance, maternal health, and health systems from governments, academia, development organizations, and foundations to assess the evidence on whether financial incentives significantly and substantially increase provision, use and quality of maternal health services, and the contextual factors that impact the effectiveness of these incentives. Evidence review teams evaluated the multidisciplinary evidence of various financial mechanisms, including supply-side incentives (e.g. performance-based financing, user fees, and various insurance mechanisms) and demand-side incentives (e.g. conditional cash transfers, vouchers, user fee exemptions, and subsidies for care-seeking). At the Summit, the teams presented a synthesis of evidence and initial recommendations on practice, policy, and research for discussion. The Summit enabled structured

    The purpose of the analysis is to identify and quantify Federal incentives that have increased the consumption of coal, oil, natural gas, and electricity. The introductory chapter is intended as a device for presenting the policy questions about the incentives that can be used to stimulate desired levels of energy development. In the theoretical chapter federal incentives were identified for the consumption of energy as Federal government actions whose major intent or result is to stimulate energy consumption. The stimulus comes through changing values of variables included in energy demand functions, thereby inducing energy consumers to move along the function in the direction of greater quantity of energy demanded, or through inducing a shift of the function to a position where more energy will be demanded at a given price. The demand variables fall into one of six categories: price of the energy form, price of complements, price of substitutes, preferences, income, and technology. The government can provide such incentives using six different policy instruments: taxation, disbursements, requirements, nontraditional services, traditional services, and market activity. The four major energy forms were examined. Six energy-consuming sectors were examined: residential, commercial, industrial, agricultural, transportation, and public. Two types of analyses of incentive actions are presented in this volume. The generic chapter focused on actions taken in 1978 across all energy forms. The subsequent chapters traced the patterns of incentive actions, energy form by energy form, from the beginning of the 20th century, to the present. The summary chapter includes the results of the previous chapters presented by energy form, incentive type, and user group. Finally, the implications of these results for solar policy are presented in the last chapter. (MCW)

  10. The response of maize production in Kenya to economic incentives

    Onono, P.A.,

    2013-06-01

    Full Text Available Agricultural development policy in Kenya has emphasised the use of incentives towards increased production and therefore self-sufficiency in maize which is a basic staple for most households. The channels used to provide incentives to maize farmers over the years include setting higher producer prices; subsidisation of inputs; provision of agricultural credit, research and extension services; construction and maintenance of roads, development of irrigation and water systems; legislative, institutional and macroeconomic reforms. Despite these efforts outputof maize has remained below domestic requirements in most years and the country continues to rely on imports to meet the deficits. Studies have assessed the responsiveness of maize to output price and reported inelastic responses and have recommended policies targeting non-price incentives to complement prices for the required increased production of maize. The studies, however, did not analyse the influence of the non-price incentives on the production of the crop. The findings of those studies are therefore deficient in explaining the relative importance of different non-price incentives and how they complement prices in influencing maize production in Kenya. This study investigated the response of maize production to both price and non-price incentives. The aim of this study was to ascertain the relative importance of non-price factors in influencing production of the crops as well as complementarity between price and non-price incentives. The findings show that maize production responds positively to its output price, development expenditures in agriculture, maize sales to marketing boards, growth in per capita GDP, liberalisation and governance reforms. However, maize production responds negatively to fertiliser price and unfavourable weather conditions. The response of maize output to its price is lower with rising inflation and grain market liberalisation.

  11. Incentive Use in Research: Protecting Vulnerable Populations from Exploitation

    Full Text Available Global investment in Medical Research and Development has markedly increased in the last few decades. However, due to the decreasing public altruism, researchers have come under increased pressures from the funding bodies to produce results. Out of desperation, some researchers have resorted to using incentives as a means of sourcing for volunteers. Consequently, the research burden has disproportionately been shared among the most vulnerable populations in the society. Incentives especially monetary ones present an ethical dilemma because of the uncertainties’ surrounding the morality, amount and type of payment, vulnerability of volunteers and possible threats to voluntary participation. Several studies done on the use of incentives in medical research have noted that financial motivation was the number one reason for subjects to volunteer in Medical research. Mutual benefit and freedom of choice by participants were given as reasons to support their use. However, scientists who are against the use of incentives believe that they are coercive or undue inducements, and may influence a subjects’ ability to give an informed consent. Guidelines exist that protect vulnerable groups from exploitation, although none sheds light into the use of incentives. Nonetheless, in the face of the waning public altruism, the benefits of using incentives far outweigh the dangers, although researchers should avoid situations where their use may become problematic. As a mode of payment to research subjects, researchers should adopt a combination of the Dickerts’ Wage and re-imbursement models as guides in quantifying the incentive.

    To achieve a sustainable working life it is important to know more about what could encourage employers to increase the use of preventive and health promotive interventions. The objective of the study is to explore and describe the employer perspective regarding what incentives influence their use of preventive and health promotive workplace interventions. Semi-structured focus group interviews were carried out with 20 representatives from 19 employers across Sweden. The economic sectors represented were municipalities, government agencies, defence, educational, research, and development institutions, health care, manufacturing, agriculture and commercial services. The interviews were transcribed verbatim and the data were analysed using latent content analysis. Various incentives were identified in the analysis, namely: "law and provisions", "consequences for the workplace", "knowledge of worker health and workplace health interventions", "characteristics of the intervention", "communication and collaboration with the provider". The incentives seemed to influence the decision-making in parallel with each other and were not only related to positive incentives for engaging in workplace health interventions, but also to disincentives. This study suggests that the decision to engage in workplace health interventions was influenced by several incentives. There are those incentives that lead to a desire to engage in a workplace health intervention, others pertain to aspects more related to the intervention use, such as the characteristics of the employer, the provider and the intervention. It is important to take all incentives into consideration when trying to understand the decision-making process for workplace health interventions and to bridge the gap between what is produced through research and what is used in practice.

    2008-01-01

    Non-conventional renewable energies have never played an important role in the Chilean energy generation system, mainly due to the economic barriers that actually exists on our country for the inclusion of these kinds of technologies. Nevertheless, the use of renewable energy system technologies have started to be an interesting issue for the Chilean government, and for that reason, the last modification of the Energy Law during 2004, usually known as ''Short Law I'', introduced the first direct incentive to renewable energy generation (specifically in the art. 71-7). In this work we analyze in detail the modification on the electric law we mentioned before, especially for geothermal and wind power generation, and we compare the economic incentive generated with the new law and the differences between the real energy costs using renewable energy systems technologies and the current energy price in Chile. It is clear from the analysis that the total incentives do not cover more than 8.3% of the price differences between incomes and costs. (author)

    Windfarm developers often have good reason to question the costs they are quoted by their local distribution company for connection to the system, and these costs can now be challenged under the 'Competition in Connection' initiative. Econnect Ltd specialise in electrical connections for renewable generation throughout the UK and Europe, and have worked on many projects where alternative connections have been designed at more competitive prices. This paper provides some examples which illustrate the importance of acquiring a thorough understanding of all power system issues and PES concerns if the most cost-effective connection is to be realised.

Studies performed by the Center for Health Incentives and Behavioral Economics at the University of Pennsylvania published between January 2006 and March 2014. Randomized, controlled trials with available participant-level data. Studies that did not use financial incentives to promote health behavior change were excluded. Participant-level data from seven studies were pooled. Meta-analysis on the pooled sample using a random-effects model with interaction terms to examine treatment effects and whether they varied by incentive structure or demographic characteristics. The pooled study sample comprised 1403 participants, of whom 35% were female, 70% were white, 24% were black, and the mean age was 48 years (standard deviation 11.2 years). In the fully adjusted model, participants offered financial incentives had higher odds of behavior change (odds ratio [OR]: 3.96; p financial incentives and gender, age, race, income, or education. When further adjusting for incentive structure, blacks had higher odds than whites of achieving behavior change (OR: 1.67; p Financial incentives designed using concepts from behavioral economics were effective for promoting health behavior change. There were no large and consistent relationships between the effectiveness of financial incentives and observable demographic characteristics. Second-order examinations of incentive structure suggest potential relationships among the effectiveness of financial incentives, incentive structure, and the demographic characteristics of race and income.

    Patient adherence to medications, particularly for conditions requiring prolonged treatment such as tuberculosis, is frequently less than ideal, and can result in poor treatment outcomes. Material incentives (given as cash, vouchers and tokens), have been used to improve adherence. To assess the effects of material incentives in people undergoing diagnostic testing, or receiving prophylactic or curative therapy, for tuberculosis. We undertook a comprehensive search of the Cochrane Infectious Diseases Group Specialized Register; Cochrane Central Register of Controlled Trials (CENTRAL); MEDLINE; EMBASE; LILACS; Science Citation Index; and reference lists of relevant publications; to 22 June 2011. Randomized controlled trials of material incentives in patients being investigated for tuberculosis, or on treatment for latent or active disease. At least two authors independently screened and selected studies, extracted data, and assessed the risk of bias. The effects of interventions are compared using risk ratios (RR), and presented with 95% confidence intervals (CI). The quality of the evidence was assessed using GRADE. We identified 11 eligible studies. Ten were conducted in the USA: in adolescents (one trial), in injection drug or cocaine users (four trials), in homeless adults (three trials), and in prisoners (two trials). One additional trial recruited malnourished men receiving active treatment for tuberculosis in Timor-Leste.Material incentives may increase the return rate for reading of tuberculin skin test results compared to normal care (two trials, 1371 participants: RR 2.16, 95% CI 1.41 to 3.29, low quality evidence).Similarly, incentives probably improve clinic re-attendance for initiation or continuation of antituberculosis prophylaxis (three trials, 595 participants: RR 1.58, 95% CI 1.27 to 1.96, moderate quality evidence), and may improve subsequent completion of prophylaxis in some settings (three trials, 869 participants: RR 1.79, 95% CI 0.70 to 4

  19. Intermediaries in Trust: Indirect Reciprocity, Incentives, and Norms

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Any trust situation involves a certain amount of risk for trustors that trustees could abuse. In some cases, intermediaries exist who play a crucial role in the exchange by providing reputational information. To examine under what conditions intermediary opinion could have a positive impact on cooperation, we designed two experiments based on a modified version of the investment game where intermediaries rated the behaviour of trustees under various incentive schemes and different role structures. We found that intermediaries can increase trust if there is room for indirect reciprocity between the involved parties. We also found that the effect of monetary incentives and social norms cannot be clearly separable in these situations. If properly designed, monetary incentives for intermediaries can have a positive effect. On the one hand, when intermediary rewards are aligned with the trustor’s interest, investments and returns tend to increase. On the other hand, fixed monetary incentives perform less than any other incentive schemes and endogenous social norms in ensuring trust and fairness. These findings should make us reconsider the mantra of incentivization of social and public conventional policy.

    In mainland China, the motivation behind voluntary blood donation is a relatively new and understudied behavior. In recent times provincial governments in China have implemented various institutional incentive measures. However, little is known regarding the effectiveness of such measures. This qualitative study investigated the nature and outcomes of some identified institutionalized mechanisms, in particular how these were created and distributed in the form of incentives for voluntary blood donation. Participatory observations were conducted at two blood donation stations and four blood collecting vehicles in Changsha city, China. In-depth interviews were conducted with 17 staff and 58 blood donors at the aforementioned venues from May to October 2008 in Changsha. Thematic analysis revealed the operation of four primary type incentives: policy-driven, symbolic, information feedback and role models, which constituted the system of institutional incentives. The current blood reimbursement system was not the primary motivation for blood donation; instead this system was a subtheme of future assurance for emergency blood needs. It was evident that symbolic incentives stressed the meaning and value of blood donation. Furthermore, post-donation information services and the inherent mechanisms of communication, enhanced by some public role models, served to draw the public to donate blood. At the institutional level, blood donation was not only informed by altruism, but also carried a system of benefit and reward for the donors and their family members. We would recommend that such arrangements, if accommodated effectively into China's health promotion strategies, would increase the likelihood of blood donation.

    Financial incentives are increasingly offered to recruit nursing personnel to work in underserved communities. The authors describe and compare the characteristics of federal, provincial and territorial financial recruitment incentive programs for registered nurses (RNs), nurse practitioners (NPs), licensed practical nurses (LPNs), registered practical nurses or registered psychiatric nurses. The authors identified incentive programs from government, health ministry and student aid websites and by contacting program officials. Only government-funded recruitment programs providing funding beyond the normal employee wages and benefits and requiring a service commitment were included. The authors excluded programs offered by hospitals, regional or private firms, and programs that rewarded retention. All provinces and territories except QC and NB offer financial recruitment incentive programs for RNs; six provinces (BC, AB, SK, ON, QC and NL) offer programs for NPs, and NL offers a program for LPNs. Programs include student loan forgiveness, tuition forgiveness, education bursaries, signing bonuses and relocation expenses. Programs target trainees, recent graduates and new hires. Funding and service requirements vary by program, and service requirements are not always commensurate with funding levels. This snapshot of government-funded recruitment incentives provides program managers with data to compare and improve nursing workforce recruitment initiatives. Copyright © 2015 Longwoods Publishing.

    In this report, we examine and compare how tradable mass-based polices and tradable rate-based policies create different incentives for energy efficiency investments. Through a generalized demonstration and set of examples, we show that as a result of the output subsidy they create, traditional rate-based policies, those that do not credit energy savings from efficiency measures, reduce the incentive for investment in energy efficiency measures relative to an optimally designed mass-based policy or equivalent carbon tax. We then show that this reduced incentive can be partially addressed by modifying the rate-based policy such that electricity savings from energy efficiency measures are treated as a source of zero-carbon generation within the framework of the standard, or equivalently, by assigning avoided emissions credit to the electricity savings at the rate of the intensity target. These approaches result in an extension of the output subsidy to efficiency measures and eliminate the distortion between supply-side and demand-side options for GHG emissions reduction. However, these approaches do not address electricity price distortions resulting from the output subsidy that also impact the value of efficiency measures. Next, we assess alternative approaches for crediting energy efficiency savings within the framework of a rate-based policy. Finally, we identify a number of challenges that arise in implementing a rate-based policy with efficiency crediting, including the requirement to develop robust estimates of electricity savings in order to assess compliance, and the requirement to track the regionality of the generation impacts of efficiency measures to account for their interstate effects.

  5. Incentive regulation of nuclear power plants by state public utility commissions

    Petersen, J.C.

    1987-12-01

    This report on incentive regulation of nuclear power plants by state public utility commissions (PUCs). Economic performance incentives established by state PUCs are applicable to the construction or operation of about 45 nuclear power reactors owned by 30 utilities in 17 states. The NRC staff monitors development of the incentives and periodically provides an updated report on all nuclear plant incentives to its regional offices. The staff maintains contact with the PUCs and the utilities responsible for implementing the incentives in order to obtain the updated information and to consider potential safety effects of the incentives. This report presents the NRC staff's concerns on potential safety effects of economic performance incentives. It also includes a plant-by-plant survey that describes the mechanics of each incentive and discusses the financial effects of the incentive on the utility-owner(s) of the plant

    Full Text Available Mobile crowd sensing (MCS is a novel sensing paradigm which can sense human-centered daily activities and the surrounding environment. The impact of mobility and selfishness of participants on the data reliability cannot be ignored in most mobile crowd sensing systems. To address this issue, we present a universal system model based on the reverse auction framework and formulate the problem as the Multiple Quality Multiple User Selection (MQMUS problem. The quality-aware incentive mechanism (QAIM is proposed to meet the quality requirement of data reliability. We demonstrate that the proposed incentive mechanism achieves the properties of computational efficiency, individual rationality, and truthfulness. And meanwhile, we evaluate the performance and validate the theoretical properties of our incentive mechanism through extensive simulation experiments.

  8. Contract-Based Incentive Mechanism for Mobile Crowdsourcing Networks

    Directory of Open Access Journals (Sweden)

    2017-09-01

    Full Text Available Mobile crowdsourcing networks (MCNs are a promising method of data collecting and processing by leveraging the mobile devices’ sensing and computing capabilities. However, because of the selfish characteristics of the service provider (SP and mobile users (MUs, crowdsourcing participants only aim to maximize their own benefits. This paper investigates the incentive mechanism between the above two parties to create mutual benefits. By modeling MCNs as a labor market, a contract-based crowdsourcing model with moral hazard is proposed under the asymmetric information scenario. In order to incentivize the potential MUs to participate in crowdsourcing tasks, the optimization problem is formulated to maximize the SP’s utility by jointly examining the crowdsourcing participants’ risk preferences. The impact of crowdsourcing participants’ attitudes of risks on the incentive mechanism has been studied analytically and experimentally. Numerical simulation results demonstrate the effectiveness of the proposed contract design scheme for the crowdsourcing incentive.

    2012-01-01

    To simulate a market introduction of Intelligent Speed Adaptation (ISA) and to study the effect of a Pay as You Speed (PAYS) concept, a field trial with 153 drivers was conducted during 2007–2009. The participants drove under PAYS conditions for a shorter or a longer period. The PAYS concept...... consisted of informative ISA linked with economic incentive for not speeding, measured through automatic count of penalty points whenever the speed limit was exceeded. The full incentive was set to 30% of a participant's insurance premium. The participants were exposed to different treatments......, with and without incentive crossed with informative ISA present or absent. The results showed that ISA is an efficient tool for reducing speeding particularly on rural roads. The analysis of speed data demonstrated that the proportion of distance driven above the speed where the ISA equipment responded (PDA...

  10. Human capital and risk aversion in relational incentive contracts

    Kvaloey, Ola

    2003-01-01

    This paper examines a self-enforced relational incentive contract between a risk neutral principal and a risk averse agent where the agent's human capital is essential in ex post realization of values. I analyse the effect of outside options on the optimal bonus level, showing how the presence of ex post outside options may impede desirable degrees of performance pay. The effect of risk aversion and incentive responsiveness is analysed by allowing for linear contracts. I show that the first order effect of these parameters are the same as in verifiable contracts, but second order effects show that the optimal bonus level's sensitivity to risk aversion and incentive responsiveness increases with the discount factor. The analysis has interesting implications on firm boundaries and specificity choices. (author)

    theory, on the other hand, argues that the relationship is opposite, so it is the degree of incentives that affects motivation. Both arguments lead to expectations of an association between public service motivation and monetary incentives, but so far this complex relationship has not been entangled......Motivation is probably one of the most important determinants for organizational performance, because it stimulates effort and effective behaviors among people in the organization. But what type of motivation should public managers rely on? The PSM literature has argued that public service...... motivation is the most important type of motivation in the delivery of public service, because it substitutes for egoistic motivation. Organizations whose members have high levels of PSM are therefore expected to be less dependent on utilitarian motivators such as monetary incentives. Motivation crowding...

    Full Text Available The goal of this article is to analyze the impact of tax incentives on research and development and compare its effectiveness to direct government support of research and development. The analysis is based on regression analysis, which compares effect of tax incentives for research and development and direct government support (as percentage of GDP in 28 countries of OECD in 2013 on innovative effectiveness of these countries measured by number of registered triadic patent families per billion GDP in the same year. Results suggest that tax incentives are more effective form of research and development support than direct government funding. Research also revealed interesting case of Switzerland’s research and development performance backed by almost none government support, which should be subject to future study.

  13. An incentive-based architecture for social recommendations

    KAUST Repository

    Bhattacharjee, Rajat

    2009-01-01

    We present an incentive-based architecture for providing recommendations in a social network. We maintain a distinct reputation system for each individual and we rely on users to identify appropriate correlations and rate the items using a system-provided recommendation language. The key idea is to design an incentive structure and a ranking system such that any inaccuracy in the recommendations implies the existence of a profitable arbitrage opportunity, hence making the system resistant to malicious spam and presentation bias. We also show that, under mild assumptions, our architecture provides users with incentive to minimize the Kullback-Leibler divergence between the ratings and the actual item qualities, quickly driving the system to an equilibrium state with accurate recommendations.

    In the present paper we consider the allocation of cost in connection networks. Agents have connection demands in form of pairs of locations they want to be connected. Connections between locations are costly to build. The problem is to allocate costs of networks satisfying all connection demands....... We use three axioms to characterize allocation rules that truthfully implement cost minimizing networks satisfying all connection demands in a game where: (1) a central planner announces an allocation rule and a cost estimation rule; (2) every agent reports her own connection demand as well as all...... connection costs; and, (3) the central planner selects a cost minimizing network satisfying reported connection demands based on estimated connection costs and allocates true connection costs of the selected network....

  16. The effect of policy incentives on electric vehicle adoption

    International Nuclear Information System (INIS)

    Langbroek, Joram H.M.; Franklin, Joel P.; Susilo, Yusak O.

    2016-01-01

    In order to increase the attractiveness of electric vehicles (EVs), packages of policy incentives are provided in many countries. However, it is still unclear how effective different policy incentives are. Also, it is questionable that they have the same impact on different groups of people. In this study, based on a stated-choice experiment, the effect of several potential policy incentives on EV-adoption, as well as the influence of socio-psychological determinants are investigated, using constructs of the Transtheoretical Model of Change (TTM) and the Protection Motivation Theory (PMT). The probability of stated EV-adoption increases if policy incentives are offered in the choice experiment, which is expected because of the decrease of the generalized cost of EV-use. The high stated valuation of free parking or access to bus lanes makes those incentives an efficient alternative to expensive subsidies. EV-adoption probability increases for people that are further in the process of behavioural change. However, the responsiveness to subsidies decreases for people in more advanced stages-of-change. People that believe EVs to be effective in decreasing the negative externalities of the current transport system and people whose travel patterns can cope with the use of EVs also have a higher probability to choose the EV. - Highlights: •Policy incentives have a positive influence on electric vehicle adoption. •Being in advanced stages-of-change to EV-adoption increases likelihood to adopt EVs. •People in more advanced stages-of-change to EV-adoption are less price-sensitive. •People with a high self-efficacy and response efficacy are more likely to adopt EVs.

    This paper uses a difference-in-differences approach, combined with propensity score matching, to identify the effect of older workers employment protection on French firms' incentives to sponsor training. Between 1987 and 2008, French firms laying off workers aged over 50 had to pay a tax...... to the unemployment insurance system, known as the Delalande tax. In 1999, the measure was subjected to a reform that increased the tax, but only for large firms. We find that this exogenous increase substantially raised firms' incentives to train workers aged 45–49 but had no impact on the training rates among...

  4. Designing PV Incentive Programs to Promote System Performance: AReview of Current Practice

    Energy Technology Data Exchange (ETDEWEB)

    Barbose, Galen; Wiser, Ryan; Bolinger, Mark

    2006-11-12

    Some stakeholders continue to voice concerns about the performance of customer-sited photovoltaic (PV) systems, particularly because these systems typically receive financial support through ratepayer- or publicly-funded programs. Although much remains to be understood about the extent and specific causes of poor PV system performance, several studies of the larger programs and markets have shed some light on the issue. An evaluation of the California Energy Commission (CEC)'s Emerging Renewables Program, for example, found that 7% of systems, in a sample of 95, had lower-than-expected power output due to shading or soiling (KEMA 2005). About 3% of a larger sample of 140 systems were not operating at all or were operating well below expected output, due to failed equipment, faulty installation workmanship, and/or a lack of basic maintenance. In a recent evaluation of the other statewide PV incentive program in California, the Self-Generation Incentive Program, 9 of 52 projects sampled were found to have annual capacity factors less than 14.5%, although reasons for these low capacity factors generally were not identified (Itron 2005). Studies of PV systems in Germany and Japan, the two largest PV markets worldwide, have also revealed some performance problems associated with issues such as shading, equipment and installation defects, inverter failure, and deviations from module manufacturers' specifications (Otani et al. 2004, Jahn & Nasse 2004). Although owners of PV systems have an inherent incentive to ensure that their systems perform well, many homeowners and building operators may lack the necessary information and expertise to carry out this task effectively. Given this barrier, and the responsibility of PV incentive programs to ensure that public funds are prudently spent, these programs should (and often do) play a critical role in promoting PV system performance.

    2010-01-01

    Full Text Available Complex ideas are best conveyed through well-designed illustrations. Up to now, computational neuroscientists have mostly relied on box-and-arrow diagrams of even complex neuronal networks, often using ad hoc notations with conflicting use of symbols from paper to paper. This significantly impedes the communication of ideas in neuronal network modeling. We present here Connectivity Pattern Tables (CPTs as a clutter-free visualization of connectivity in large neuronal networks containing two-dimensional populations of neurons. CPTs can be generated automatically from the same script code used to create the actual network in the NEST simulator. Through aggregation, CPTs can be viewed at different levels, providing either full detail or summary information. We also provide the open source ConnPlotter tool as a means to create connectivity pattern tables.

    An improvement in pulse generators is described by which there are produced pulses of a duration from about 1 to 10 microseconds with a truly flat top and extremely rapid rise and fall. The pulses are produced by triggering from a separate input or by modifying the current to operate as a free-running pulse generator. In its broad aspect, the disclosed pulse generator comprises a first tube with an anode capacitor and grid circuit which controls the firing; a second tube series connected in the cathode circuit of the first tube such that discharge of the first tube places a voltage across it as the leading edge of the desired pulse; and an integrator circuit from the plate across the grid of the second tube to control the discharge time of the second tube, determining the pulse length.
