    2013-01-01

    This brief guides the reader through three basic Internet resource pricing models using an Internet cost analysis. Addressing the evolution of service types, it presents several corresponding mechanisms which can ensure pricing implementation and resource allocation. The authors discuss utility optimization of network pricing methods in economics and underline two classes of pricing methods including system optimization and entities' strategic optimization. The brief closes with two examples of the newly proposed pricing strategy helping to solve the profit distribution problem brought by P2P

    Full Text Available Purpose: With the rapid progress of Internet of Things technology, the information service of IoT has got unprecedented development, and plays an increasingly important role in real life. For the increasing demand of information service, the pricing of information service becomes more important. This paper aims to analyze the strategic options and payoff function between information provider and intermediaries based on Stackelberg game. Firstly, we describe information service delivery method based on the Internet of Things specific function. Secondly, we calculate the consumer demand for the information service. Finally, we explain two kinds of strategic options by the game theory, and then discuss the optimal pricing method of information services based on profit maximization.Design/methodology/approach: To achieve this objective, Considering the consumer perceived value of Internet of Things Service changing, we establish a Stackelberg model in which the supplier is the leader followed by the middleman. Then, we compare the advantages of using individual pricing with that of bundling pricing.Findings: The results show that whether information providers adopt bundling pricing strategy or individual pricing strategy depends on the cost of perception equipment, if information providers want to adopt individual pricing strategy, the variation of consumers’ perception value of information services must meet certain conditions.Research limitations/implications: the providers make price for the information service, in addition to continuously improve the quality of information service, it also devotes resources to tapping and understanding market information, such as the sensor device price, the variation of perception value of information services and so on, so as to create competitive advantage. This paper is just a preliminary model, it does not take into account the effect of mixed bundling.Originality/value: In this research, a new model for

    Directory of Open Access Journals (Sweden)

    Full Text Available In the article, some recent literature on Internet pricing is surveyed. The author looks at the topic by setting it in the more general framework of the analysis of activities that can be regarded as similar to Internet from the technological and economic point of view. In particular, attention is focused on the problem of the divergence between private and social costs when there occurs network congestion and the problem of efficient prices in activities characterized by the existence of peak-loads. The author argues that dealing with such issues in the context of Internet cannot be reduced to a straightforward application of traditional results of welfare economics and the literature on peak-load pricing. In a competitive market with similar features to the market for Internet services, it is well possible that there do not exist incentives that induce firms to adopt price systems such as to prevent and/or eliminate congestion. Further theoretical and analytical developments are then in order.  JEL Codes: L86, L11Keywords: Pricing

  8. Pricing the Services in Dynamic Environment: Agent Pricing Model

    Science.gov (United States)

    Žagar, Drago; Rupčić, Slavko; Rimac-Drlje, Snježana

    New Internet applications and services as well as new user demands open many new issues concerning dynamic management of quality of service and price for received service, respectively. The main goals of Internet service providers are to maximize profit and maintain a negotiated quality of service. From the users' perspective the main goal is to maximize ratio of received QoS and costs of service. However, achieving these objectives could become very complex if we know that Internet service users might during the session become highly dynamic and proactive. This connotes changes in user profile or network provider/s profile caused by high level of user mobility or variable level of user demands. This paper proposes a new agent based pricing architecture for serving the highly dynamic customers in context of dynamic user/network environment. The proposed architecture comprises main aspects and basic parameters that will enable objective and transparent assessment of the costs for the service those Internet users receive while dynamically change QoS demands and cost profile.

    Science.gov (United States)

    Tellis, G J

    1987-01-01

    This paper discusses the strategic role of the pricing of medical services. Strategic pricing is a creative process that can be a vital means of defining marketing segments, differentiating services, and gaining a competitive advantage. The central issue in strategic pricing is creatively using the principle of cross-subsidies or shared economies over consumer groups, service sets, or competitors. This principle yields a rich set of pricing strategies that can be used in response to various environments.

    Full Text Available This paper deals with the consumer's preferences in booking hotel services over the internet. A conjoint analysis was used in establishing whether the price is the most important factor in deciding on a hotel service and which elements of the service can be used as a competitive advantage. Although the price does play a pivotal role in the consumer's decision, within an acceptable price range he will take into account the bonuses offered by the hotel. Among the bonuses, free parking and free internet access play an important role, while free access to pornographic films and free wine with dinner are not an important factor. Room colour does not play a role in the consumer's decision making process regarding hotel services.

    Science.gov (United States)

    Kim, Jun Woo; Ha, Sung Ho

    2014-01-01

    Information-intensive Web services such as price comparison sites have recently been gaining popularity. However, most users including novice shoppers have difficulty in browsing such sites because of the massive amount of information gathered and the uncertainty surrounding Web environments. Even conventional price comparison sites face various problems, which suggests the necessity of a new approach to address these problems. Therefore, for this study, an intelligent product search system was developed that enables price comparisons for online shoppers in a more effective manner. In particular, the developed system adopts linguistic price ratings based on fuzzy logic to accommodate user-defined price ranges, and personalizes product recommendations based on linguistic product clusters, which help online shoppers find desired items in a convenient manner.

    1999-01-01

    The paper presents an intuitively logical split between: (a) embedded, (b) operating, and (c) expansion cost based pricing and methodologies for implementation, for transmission services. A conceptually straightforward mechanism for the equitable allocation of transmission network embedded cost recovery based on capacity-use and reliability benefit is proposed, expansion cost is charged on a long-run marginal cost basis and finally, operating cost recovery is based on short-run marginal pricing. This is followed by co-ordinating these alternatives and integrating the pricing mechanisms to achieve appropriate price signals for bulk power users of transmission systems. (author)

    International Nuclear Information System (INIS)

    Valle, A.P.D.; Watkins, G.C.

    1990-01-01

    In 1982, the Canadian National Energy Board and McGill University sponsored a conference on pipeline regulation in an inflationary era, focussing especially on the possible introduction of some form of tariff levelling. Ironically, shortly after the conference proceedings were published the very concerns addressed receded: inflation declined markedly and emerging weaknesses in oil and gas prices saw the demise or deferral of big projects with large up-front investments, the very projects which had excited interest in developing new regulatory techniques. This paper is organized in three main sections. Section I outlines the problems raised by traditional tariff regulation. Section II develops and discusses theoretical aspects of alternative rate structures. Section II focuses on practical problems of implementing rate structures that, on the face of it, have a better economic rationale than cost-of-service style pricing. Concluding remarks are made in Section IV

    Huang, B. Q.; Kechadi, M.-T.; Buckley, B.

    Although churn prediction has been an area of research in the voice branch of telecommunications services, more focused studies on the huge growth area of Broadband Internet services are limited. Therefore, this paper presents a new set of features for broadband Internet customer churn prediction, based on Henley segments, the broadband usage, dial types, the spend of dial-up, line-information, bill and payment information, account information. Then the four prediction techniques (Logistic Regressions, Decision Trees, Multilayer Perceptron Neural Networks and Support Vector Machines) are applied in customer churn, based on the new features. Finally, the evaluation of new features and a comparative analysis of the predictors are made for broadband customer churn prediction. The experimental results show that the new features with these four modelling techniques are efficient for customer churn prediction in the broadband service field.

The great impact that IoT will bring to service offerings and its spatial consequence is disproportionate to how much research has been done in this area. The paper aims to understand how the adoption of IoT affects the spatial ramification of service offerings and service business. After the theoretical framework and research method, part three explains what the implications of IoT in service context are, why and how IoT enables innovation in services and the current obstacles. Part four further discusses what could be the spatial ramification with the case of China emerging IoT industry in city Wuxi.

  11. QoS Predictability of Internet Services

    Science.gov (United States)

    Bilski, Tomasz

    The paper presents problems of QoS (Quality of Service) predictability of network services (mainly in WAN environment). In the first part we present general remarks on QoS predictability problem, mentioning some research projects and available resources. The main part of the paper deals with QoS predictability in long-term as well as short-term viewpoints. We will try to answer a question: is it possible to predict network QoS/performance level with a use of statistical data from the past? The term quality of service has many meanings ranging from the user's qualitative perception of the service to a set of quantitative connection parameters (RTT (Round Trip Time), throughput, loss packet rate) necessary to achieve particular service quality. In the paper we will mostly use the second meaning of the term based on RFC 2386 [1]. Analyzed, statistical data on Internet performance are taken from the IEPM (Internet End-to-end Performance Measurement) database.

  12. Retail Services and Pricing Decisions in a Closed-Loop Supply Chain with Remanufacturing

    Directory of Open Access Journals (Sweden)

    2015-02-01

    Full Text Available Environmental and social responsibilities have led many manufacturers to used products recovery. Meanwhile, many manufacturers nowadays sell products via indirect retailer channels and direct Internet channels. This paper models a dual-channel closed-loop supply chain to improve the sustainability of products. We apply the two-stage optimization technique and the Nash game to examine the impacts of the retail services and the degree of customer loyalty to the retail channel on the pricing of players in a centralized and a decentralized dual-channel supply chain. Our results show that the retail services have a great impact on the manufacturer and the retailer’s pricing strategies. We also compare the differences of pricing strategies between a centralized and a decentralized dual-channel supply chain and suggest the optimal retail services and pricing decisions for the players in the supply chain.

  17. How does market concern derived from the Internet affect oil prices?

    International Nuclear Information System (INIS)

    Guo, Jian-Feng; Ji, Qiang

    2013-01-01

    Highlights: • The impact of market concern derived from the Web on oil volatility is analysed. • It has an equilibrium relationship between oil prices and long-run market concern. • The short-run market concerns have an asymmetric influence on oil price volatility. • The Internet can exaggerate the impact of information shocks on oil price. - Abstract: With the acceleration of oil marketisation and the rapid development of electronic information carriers, external information shocks can be easily and quickly transmitted to the oil market through the Internet. This paper analyses the impact of short- and long-run market concerns, derived from search query volumes in Google for different domains around the oil market on oil volatility using co-integration and the modified EGARCH model. Empirical results suggest there is a long-term equilibrium relationship between oil prices and long-run market concern for oil prices and oil demand. The short-run market concerns for the 2008 financial crisis and the Libyan war convulsion have a significant and asymmetric influence on oil price volatility. This indicates that market concern transmitted through the Internet can strengthen the linkage between oil price changes and external events by influencing the expectation of market traders, and to some extent it can exaggerate the impact of nonfundamental information shocks

    1995-12-01

    Unbundling and restructuring of local distribution services is the focus of the natural gas industry. As a result of regulatory reforms, a competitive local distribution market has emerged, and the validity of traditional cost-based regulation is being questioned. One alternative is to completely unbundle local distribution services and transform the local distribution company into a common carrier for intrastate transportation services. Three kinds of alternative pricing mechanisms are examined. For firm intrastate transportation services, cost-based pricing is the preferred method unless it can be shown that a competitive secondary market can be established and maintained. Pricing interruptible transportation capacity is discussed

  5. Is the Internet making markets more efficient? The evidence according to price indicators in Spain

    Directory of Open Access Journals (Sweden)

    Ferran Sabate

    2009-04-01

    Full Text Available It has been theorized that low search costs associated with e-commerce imply greater levels of efficiency relative to the conventional retail channels. Multiple empirical studies confirm this hypothesis concerning price level, although the evidence is mixed relative to price dispersion. This article empirically compares the efficiency of the Internet with the conventional retail channel through 4 price indicators for the CD market. The results, based on 1,603 prices collected in Spain, are surprising. The conventional channel shows greater efficiency for both posted and final prices. These findings together with the coincident results of other reviewed studies would suggest key factors related to the development of e-commerce. Implications of the study and future considerations are discussed.

  7. Market interdependence among commodity prices based on information transmission on the Internet

    Science.gov (United States)

    Ji, Qiang; Guo, Jian-Feng

    2015-05-01

    Human behaviour on the Internet has become a synchro-projection of real society. In this paper, we introduce the public concern derived from query volumes on the Web to empirically analyse the influence of information on commodity markets (e.g., crude oil, heating oil, corn and gold) using multivariate GARCH models based on dynamic conditional correlations. The analysis found that the changes of public concern on the Internet can well depict the changes of market prices, as the former has significant Granger causality effects on market prices. The findings indicate that the information of external shocks to commodity markets could be transmitted quickly, and commodity markets easily absorb the public concern of the information-sensitive traders. Finally, the conditional correlation among commodity prices varies dramatically over time.

    The Internet of Energy (IoE) represents a novel paradigm where electrical power systems work cooperatively with smart devices to increase the visibility of energy consumption and create safer, cleaner and sustainable energy systems. The implementation of IoE services involves the use of multiple components, like embedded systems, power electronics or sensors, which are an essential part of the infrastructure dedicated to the generation and distribution energy and the one required by the final consumer. This article focuses on the latter and presents a smart socket system that collects the information about energy price and makes use of sensors and actuators to optimize home energy consumption according to the user preferences. Specifically, this article provides three main novel contributions. First, what to our knowledge is the first hardware prototype that manages in a practical real-world scenario the price values obtained from a public electricity operator is presented. The second contribution is related to the definition of a novel wireless sensor network communications protocol based on Wi-Fi that allows for creating an easy-to-deploy smart plug system that self-organizes and auto-configures to collect the sensed data, minimizing user intervention. Third, it is provided a thorough description of the design of one of the few open-source smart plug systems, including its communications architecture, the protocols implemented, the main sensing and actuation components and the most relevant pieces of the software. Moreover, with the aim of illustrating the capabilities of the smart plug system, the results of different experiments performed are shown. Such experiments evaluate in real-world scenarios the system’s ease of use, its communications range and its performance when using HTTPS. Finally, the economic savings are estimated for different appliances, concluding that, in the practical situation proposed, the smart plug system allows certain energy

    2018-02-01

    Full Text Available Prospective customers of financial and insurance products can be targeted based on the profit the provider expects to earn from them. We present a model for individual expected profit and two alternatives for calculating optimal personalized prices that maximize the expected profit. For one of these alternatives, we obtain a closed-form expression for the price offered to each prospective customer; for the other, we need to use a numerical approximation. In both approaches, the profits generated by prospective customers are not immediately observed, given that the products sold by these companies have a risk component. We assume that willingness to pay is heterogeneous and apply our methodology using real data from a European insurance company. Our study indicates that a substantial boost in profits can be expected when applying the simplest optimal pricing method proposed.

  18. Dynamic Pricing for Resource Consumption in Cloud Service

    Directory of Open Access Journals (Sweden)

    Bin Cao

    2018-01-01

    Full Text Available This paper studies dynamic pricing for cloud service where different resources are consumed by different users. The traditional cloud resource pricing models can be divided into two categories: on-demand service and reserved service. The former only takes the using time into account and is unfair for the users with long using time and little concurrency. The latter charges the same price to all the users and does not consider the resource consumption of users. Therefore, in this paper, we propose a flexible dynamic pricing model for cloud resources, which not only takes into account the occupying time and resource consumption of different users but also considers the maximal concurrency of resource consumption. As a result, on the one hand, this dynamic pricing model can help users save the cost of cloud resources. On the other hand, the profits of service providers are guaranteed. The key of the pricing model is how to efficiently calculate the maximal concurrency of resource consumption since the cost of providers is dynamically varied based on the maximal concurrency. To support this function in real time, we propose a data structure based on the classical B+ tree and the implementation for its corresponding basic operations like insertion, deletion, split, and query. Finally, the experiment results show that we can complete the dynamic pricing query on 10 million cloud resource usage records within 0.2 seconds on average.

  20. The Impact of Price Comparison Service on Pricing Strategy in a Dual-Channel Supply Chain

    Directory of Open Access Journals (Sweden)

    Qi Xu

    2013-01-01

    Full Text Available Recently, price comparison service (PCS websites are more and more popular due to its features in facilitating transparent price and promoting rational purchase decision. Motivated by the industrial practices, in this study, we examine the pricing strategies of retailers and supplier in a dual-channel supply chain influenced by the signals of PCS. We categorize and discuss three situations according to the signal availability of PCS, under which the optimal pricing strategies are derived. Finally, we conduct a numerical study and find that in fact the retailers and supplier are all more willing to avoid the existence of PCS with the objective of profit maximization. When both of retailers are affected by the PCS, the supplier is more willing to reduce the availability of price information. Important managerial insights are discussed.

  1. Valuing ecosystem services. A shadow price for net primary production

    International Nuclear Information System (INIS)

    Richmond, Amy; Kaufmann, Robert K.; Myneni, Ranga B.

    2007-01-01

    We analyze the contribution of ecosystem services to GDP and use this contribution to calculate an empirical price for ecosystem services. Net primary production is used as a proxy for ecosystem services and, along with capital and labor, is used to estimate a Cobb Douglas production function from an international panel. A positive output elasticity for net primary production probably measures both marketed and nonmarketed contributions of ecosystems services. The production function is used to calculate the marginal product of net primary production, which is the shadow price for ecosystem services. The shadow price generally is greatest for developed nations, which have larger technical scalars and use less net primary production per unit output. The rate of technical substitution indicates that the quantity of capital needed to replace a unit of net primary production tends to increase with economic development, and this rate of replacement may ultimately constrain economic growth.

    Della Mea, V; Beltrami, C A

    2000-01-01

    The last five years experience has definitely demonstrated the possible applications of the Internet for telepathology. They may be listed as follows: (a) teleconsultation via multimedia e-mail; (b) teleconsultation via web-based tools; (c) distant education by means of World Wide Web; (d) virtual microscope management through Web and Java interfaces; (e) real-time consultations through Internet-based videoconferencing. Such applications have led to the recognition of some important limits of the Internet, when dealing with telemedicine: (i) no guarantees on the quality of service (QoS); (ii) inadequate security and privacy; (iii) for some countries, low bandwidth and thus low responsiveness for real-time applications. Currently, there are several innovations in the world of the Internet. Different initiatives have been aimed at an amelioration of the Internet protocols, in order to have quality of service, multimedia support, security and other advanced services, together with greater bandwidth. The forthcoming Internet improvements, although induced by electronic commerce, video on demand, and other commercial needs, are of real interest also for telemedicine, because they solve the limits currently slowing down the use of Internet. When such new services will be available, telepathology applications may switch from research to daily practice in a fast way.

    In designing default service for competitive retail markets, demand response has been an afterthought at best. But that may be changing, as states that initiated customer choice in the past five to seven years reach an important juncture in retail market design and consider an RTP-type default service for large commercial and industrial customers. The authors describe the experience to date with RTP as a default service, focusing on its role as an instrument for cultivating price-responsive demand. (author)

  10. Optimal pricing of transmission and distribution services in electricity supply

    International Nuclear Information System (INIS)

    Farmer, E.D.; Cory, B.J.; Perera, B.L.P.P.

    1995-01-01

    A new strategy for the separate pricing of transmission and distribution services in electricity supply is formulated and evaluated. The proposed methodology is a multivariate transmission generalisation of the method of peak load pricing previously applied to the optimal time-of-use pricing of generation on a power system with diverse generation technologies and with elastic demand. The method allocates both capacity and operational costs on a time-of-use basis, in an optimal manner, that avoids cross-subsidisation both between differing supply system participants and differing times of usage. The method is shown to promote the optimal development of the transmission, distribution or interconnecting systems, rewarding justified investments in transmission capacity and discouraging overinvestment. It also leads to appropriate returns on invested capital without significant 'revenue reconciliation'. This contrasts with SRMC pricing as is shown by a comparative revenue evaluation. It is concluded that the method has wide potential application in electricity supply. (author)

    Full Text Available With the end of 2014, the domestic banking system has serious difficulties with the availability of capital for lending and investment programs. Problems based on international political divisions, and their resolution lies in the distant future. in these circumstances, the government is concerned about the development of the Russian banking system in terms of ensuring their competitiveness in the international arena. foreign capital has always been a cheap resource for the domestic banking system, the problem area remains its state at the time of lifting of sanctions. Nowadays banks are forced to use different competition methods in target to adapt to environmental changes and ensure competitive success. So the development of methods for price and non-price competition has economic importance. Analysis of qualitative methodological foundations in banks service revealed strong background. Based on neoteric qualitative evaluation methodology, authors developed method for price and non-price competitiveness. It defines variables of price and non-price competitiveness, to set the value factors, to identify the closest competitors, and to set the position of a particular bank among other participants. It also helps to shape competitors dossier based on the evaluated score.

  13. Optimal Nonlinear Pricing, Bundling Commodities and Contingent Services

    International Nuclear Information System (INIS)

    Podesta, Marion; Poudou, Jean-Christophe

    2008-01-01

    In this paper, we propose to analyze optimal nonlinear pricing when a firm offers in a bundle a commodity and a contingent service. The paper studies a mechanism design where all private information can be captured in a single scalar variable in a monopoly context. We show that to propose the package for commodity and service is less costly for the consumer, the firm has lower consumers' rent than the situation where it sells their good and contingent service under an independent pricing strategy. In fact, the possibility to use price discrimination via the supply of package is dominated by the fact that it is costly for the consumer to sign two contracts. Bundling energy and a contingent service is a profitable strategy for a energetician monopoly practising optimal nonlinear tariff. We show that the rates of the energy and the contingent service depend to the optional character of the contingent service and depend to the degree of complementarity between commodities and services.

    Kirsch, L.D.; Rajaraman, R.; Clark, C.

    1997-12-01

    In the competitive electric power markets of the imminent future, reserves will be the second largest generation service in terms of their revenues and profits. Because reserves will be more widely traded than at present, they will be provided by the cheapest available sources regardless of the ownership of those sources. Price will determine the willingness of generators and consumers to provide reserve services; and it may also determine the willingness of reserve users to purchase reserve services. This report presents a methodology by which generation firms and merchant firms can profitably cost and price the reserve services that they offer. The methodology is generally applicable to a wide range of market structures that such firms might face

  20. Pricing health care services: applications to the health maintenance organization.

    Science.gov (United States)

    Sweeney, R E; Franklin, S P

    1986-01-01

    This article illustrates how management in one type of service industry, the health maintenance organization (HMO), have attempted to formalize pricing. This effort is complicated by both the intangibility of the service delivered and the relatively greater influence in service industries of non-cost price factors such as accessibility, psychology, and delays. The presentation describes a simple computerized approach that allows the marketing manager to formally estimate the effect of incremental changes in rates on the firm's projected patterns of enrollment growth and net revenues. The changes in turn reflect underlying variations in the mix of pricing influences including psychological and other factors. Enrollment projections are crucial to the firm's financial planning and staffing. In the past, most HMO enrollment and revenue projections of this kind were notoriously unreliable. The approach described here makes it possible for HMOs to fine-tune their pricing policies. It also provides a formal and easily understood mechanism by which management can evaluate and reach consensus on alternative scenarios for enrollment growth, staff recruitment and capacity expansion.

    2015-01-01

    Full Text Available To examine when the manufacturer and dominant retailer open their own Internet stores and how setting prices to ensure opening Internet stores are profitable. We consider a two-echelon supply chain with one manufacturer and one dominant retailer. The retailer has a physical store in a monopolist market. Depending on whether the Internet stores are opened successfully by them, we firstly obtain equilibrium prices and profits under four possible supply chain structures. Secondly, we identify several strategic conditions when it is optimal to open an Internet store for the manufacturer and dominant retailer and discuss its implications. It is interesting to note that multichannel retailing is not necessarily the best strategy for the dominant retailer. In addition, we investigate the impacts of problem parameters (the dominant retailer’s bargaining power and consumers’ disutility of purchasing a product from Internet store on the manufacturer and dominant retailer’s pricing policies. We find that the manufacturer’s optimal price at her Internet store is not always being lower than the dominant retailer’s. Finally, we conduct numerical examples to illustrate the theoretical results.

    Oliver, Dave; Livermore, Celia Romm; Farag, Neveen Awad

    This chapter describes research that identifies and classifies the dimensions of self-service activity enabled through the Internet. Self-service is effected by organizations providing ways and means whereby customers perform tasks related to the procurement of goods and services. We describe how an instrument used to measure Internet-based self-service was developed, validated and applied. The results from applying the instrument to a large number of Web sites, covering a range of industries, countries and cultures, are analyzed and discussed. The study presents a model in which type of industry, level of technological development, income and cultural factors are proposed as explanatory variables for Web-based self-service. We conclude with an assessment of this program of research’s achievements so far.

  7. Price elasticity of expenditure across health care services.

    Science.gov (United States)

    Duarte, Fabian

    2012-12-01

    Policymakers in countries around the world are faced with rising health care costs and are debating ways to reform health care to reduce expenditures. Estimates of price elasticity of expenditure are a key component for predicting expenditures under alternative policies. Using unique individual-level data compiled from administrative records from the Chilean private health insurance market, I estimate the price elasticity of expenditures across a variety of health care services. I find elasticities that range between zero for the most acute service (appendectomy) and -2.08 for the most elective (psychologist visit). Moreover, the results show that at least one third of the elasticity is explained by the number of visits; the rest is explained by the intensity of each visit. Finally, I find that high-income individuals are five times more price sensitive than low-income individuals and that older individuals are less price-sensitive than young individuals.

    Directory of Open Access Journals (Sweden)

    M. L. Gruzdeva

    2018-01-01

    Full Text Available Introduction: The article is devoted to the use of various means and technologies of the Internet on technology lessons. As the authors of the article show, recently a lot of sites, applicable for joint work, so-called Web 2.0 tools have been developed and put into operation. Many of them can facilitate the work of teachers, make the material more visible, more quickly monitor the performance of homework, etc. The authors are sure that such services as google-tables and google-presentations can reduce the organizational time in the lesson, which is so expensive for practical classes, will make it possible to disassemble more new material, increase the efficiency and speed of the practical work.Materials and methods: The article examines different methods of organizing a lesson using Internet services: when studying a new topic, when working on a project, with differentiated work in a lesson, etc.The results of the research: The article describes the Internet services that the technology teachers can use in their professional activities: a graphical service for creating the layout and interior of the house Planoplan, services that allow you to create schemes for embroidery and share the already created schemes with other embroiderers (igolki.net, x.fanreal.ru, crosti.ru and othersDiscussion and conclusion: The article discusses the complexity of the use of virtual services in the study of the subject of Technology, namely the fact that the student needs to learn the manual operations used for centuries that were not worked out on one generation of students with virtually no changes in the methodology. In addition, there are practically no services developed specifically for the method of teaching the subject of Technology. Internet technologies have firmly taken their positions in the life of modern society. Teachers should use all the tools that can attract the attention of a new generation to teach them their subject.

    International Nuclear Information System (INIS)

    Wang Peng; Zareipour, Hamidreza; Rosehart, William D.

    2011-01-01

    In this paper, characteristics of the prices of reserves and regulation services in the Ontario, New York and ERCOT electricity markets are studied. More specifically, price variability, price jumps, long-range correlation, and non-linearity of the prices are analyzed using the available measures in the literature. For the Ontario electricity market, the prices of 10-min spinning, 10-min non-spinning, and 30-min operating reserves for the period May 1, 2002 to December 31, 2007 are analyzed. For the New York market, prices of the same reserves plus regulation service are studied for the period February 5, 2005 to December 31, 2008. For the ERCOT market, we analyze the prices of responsive reserve, regulation up and regulation down services, for the period January 1, 2005 to December 31, 2009. The studied characteristics of operating reserve and regulation prices are also compared with those of energy prices. The findings of this paper show that the studied reserve and regulation prices feature extreme volatility, more frequent jumps and spikes, different peak price occurrence time, and lower predictability, compared to the energy prices. - Research highlights: → We examine various statistical characteristics of reserve and regulation prices. → We compare characteristics of reserve and regulation and energy prices. → Reserve and regulation prices feature different patterns from energy prices. → Reserve and regulation prices are more dispersive and volatile than energy price.

  19. THE CONCEPTUALISATION AND OPERATIONAL MEASUREMENT OF PRICE FAIRNESS PERCEPTION IN MASS SERVICE CONTEXT

    Directory of Open Access Journals (Sweden)

    Saowanee Srikanjanarak

    2009-01-01

    Full Text Available This paper aims to develop a measure of price fairness perception by extending price fairness conceptualisation to a multi-scale measure, thereby capturing its complexity in a mass service context. The service context is becoming increasingly competitive, particularly in the telecommunication industry, where a variety of service options is offered (e.g., mobile phone services. A review of price fairness perception literature usually focuses on the equity and social exchange theory and upon findings from exploratory research of the current market situation. In this article, the measure is conceptualised to entail a more extensive set of dimensions. These dimensions include the following: flexible price, reasonable price, acceptable price and superior price. Previous researchers have used actual price to focus on the structure and price comparison of competitors within the service industry. In contrast, this research has focused on the price comparison in terms of relative price. Additionally, we use a survey to elicit responses from 998 individual users of prepaid mobile phone services in Thailand. The results indicate a valid and reliable measure of price fairness perception, permitting us to understand how customers perceive that a price offered by service providers is fair. This understanding will help managers (and their respective organisations to design an appropriate price strategy that fits what their customer's wants and needs while fostering a long-term relationship with them.

  20. A study of pricing and trading model of Blockchain & Big data-based Energy-Internet electricity

    Fan, Tao; He, Qingsu; Nie, Erbao; Chen, Shaozhen

    2018-01-01

    The development of Energy-Internet is currently suffering from a series of issues, such as the conflicts among high capital requirement, low-cost, high efficiency, the spreading gap between capital demand and supply, as well as the lagged trading & valuation mechanism, any of which would hinder Energy-Internet's evolution. However, with the development of Blockchain and big-data technology, it is possible to work out solutions for these issues. Based on current situation of Energy-Internet and its requirements for future progress, this paper demonstrates the validity of employing blockchain technology to solve the problems encountered by Energy-Internet during its development. It proposes applying the blockchain and big-data technologies to pricing and trading energy products through Energy-Internet and to accomplish cyber-based energy or power's transformation from physic products to financial assets.

    2015-01-01

    Full Text Available This paper sets two manufacturers on the market. One is traditional manufacturer, which produces new products, and the other remanufactures by recycling used products. Two manufacturers sell products to customers through one retailer and also provide product-related services. Three participators decide prices and service levels independently. We discuss the optimal decision of prices, service levels, demands, and profits in three scenarios: Manufacturers Stackelberg, Retailer Stackelberg, and Nash Equilibrium. We also study the influence of customer acceptance of remanufactured product (θ on participators’ decisions. With the increase of θ, new product profit reduces; remanufactured product profit increases at the beginning and then decreases. Retailer profit grows steadily. In Manufacturers Stackelberg, new and remanufactured products can get the maximum profits, and retailer only has the minimum profit. In Retailer Stackelberg, retailer can get the maximum profit; new product only has the minimum profit and remanufactured product has the medium gain. In Nash Equilibrium, new product and retailer have the medium gains, and remanufactured product has the minimum profit.

    2016-10-01

    To ensure that end-users and consumers have access to comprehensive, comparable and user-friendly information regarding the Internet access service quality, it is necessary to implement and regularly renew a set of legislative regulatory acts and to provide monitoring of the quality of Internet access services regarding the current European Regulatory Framework. The actual situation regarding the quality of service monitoring solutions in different European countries depends on national regulatory initiatives and public awareness. The service monitoring solutions are implemented using different measurement methodologies and tools. The paper investigates the practical implementations for developing a harmonising approach to quality monitoring in order to obtain objective information on the quality of Internet access services on mobile networks.

    GENCOs in restructured systems are compensated for selling energy in the market. In a restructured market, a mechanism is required to entice participants in the market to provide ancillary services and to ensure adequate compensation that would guarantee its economic viability. The ISO controls the dispatch of generation, manages the reliability of the transmission grid, provides open access to the transmission, buys and provides ancillary services as required, coordinates day-ahead, hour-ahead schedules and performs real time balancing of load and generation, settles real time imbalances and ancillary services sales and purchases. The ISO, also, administers congestion management protocols for the transmission grid. Since the ISO does not own any generating units it must ensure that there is enough reserves for maintaining reliability according to FERC regulations, and sufficient unloaded generating capacity for balancing services in a real-time market. The ISO could meet these requirements by creating a competitive market for ancillary services, which are metered and remain unbundled to provide an accurate compensation for each supplier and cost to each consumer, In this study, we give an overview for restructuring and ancillary services in a restructured power marketplace. Also, we discuss the effect of GENCOs' actions in the competitive energy and ancillary service markets. In addition, we propose an auction market design for hedging ancillary service costs in California market. Furthermore, we show how to include the n-1 and voltage contingencies in security constrained unit commitment. Finally, we present two approaches for GENCOs' unit commitment in a restructured power market; one is based on game theory and the other is based on market price forecasting. In each of the two GENCOs' unit commitment approaches, we discuss the GENCOs' optimal bidding strategies in energy and ancillary service markets to maximize the GENCOs' profit.

    2001-01-01

    Rapid growth in the number and sophistication of energy management companies has been observed in the wake of rising energy prices. These companies offer energy-efficiency consulting services to utilities, government and industry with the promise of improved cost efficiency, marketplace competitiveness and environmental commitments. The environmental benefits result from the reduction in emissions and pollutants associated with power production and natural gas used for space heating. In general, the stock in trade of these energy management companies is the energy audit involving evaluation of existing equipment in buildings and facilities and the resulting recommendations to install energy-efficient equipment such as lighting retrofits, boiler replacement, chiller replacement, variable speed drives, high-efficiency motors, improved insulation and weather proofing, water heaters and piping. The North American market for energy management services was estimated in 1997 at $208 billion (rising to $350 billion by 2004). Current market penetration is less than two per cent

    The price terms in wheeling contracts very substantially, reflecting the differing conditions affecting the parties contracting for the service. These terms differ in the manner in which rates are calculated, the formulas used, and the philosophy underlying the accord. For example, and EEI study found that firm wheeling rates ranged from 20 cents to $1.612 per kilowatt per month. Nonfirm rates ranged from .15 mills to 5.25 mills per kilowatt-hour. The focus in this chapter is on cost-based rates, reflecting the fact that the vast majority of existing contracts are based on rate designs reflecting embedded costs. This situation may change in the future, but, for now, this fact can't be ignored

  9. Optimal pricing policies for services with consideration of facility maintenance costs

    Yeh, Ruey Huei; Lin, Yi-Fang

    2012-06-01

    For survival and success, pricing is an essential issue for service firms. This article deals with the pricing strategies for services with substantial facility maintenance costs. For this purpose, a mathematical framework that incorporates service demand and facility deterioration is proposed to address the problem. The facility and customers constitute a service system driven by Poisson arrivals and exponential service times. A service demand with increasing price elasticity and a facility lifetime with strictly increasing failure rate are also adopted in modelling. By examining the bidirectional relationship between customer demand and facility deterioration in the profit model, the pricing policies of the service are investigated. Then analytical conditions of customer demand and facility lifetime are derived to achieve a unique optimal pricing policy. The comparative statics properties of the optimal policy are also explored. Finally, numerical examples are presented to illustrate the effects of parameter variations on the optimal pricing policy.

    2018-01-01

    This paper studies the Retailer Stackelberg game in a supply chain consisting of two manufacturers and one retailer where they compete simultaneously under three factors including price, service and simple price discount contract. It is assumed that the second manufacturer provides service directly to his customers, and the retailer provides service for the first product’s customers, while the retailer buys the first product under price discount from the first manufacturer. The analysis of the optimal equilibrium solutions and the results of the numerical examples show that if a manufacturer chooses the appropriate range of discount rate, he will gain more profit than when there is no discount given to the retailer. This situation can be considered as an effective tool for the coordination of the first manufacturer and the retailer to offer discount by manufacturer and to provide the service by the retailer. We obtain equilibrium solution of Retailer Stackelberg game and analyze the numerical examples under two cases: a) the manufacturers sell their products to the retailer without price discount contract. b) The first manufacturer sells his products to the retailer with the simple price discount contract. The preliminary results show that the service and the price discount contract can improve the performance of supply chain. PMID:29649315

    This paper studies the Retailer Stackelberg game in a supply chain consisting of two manufacturers and one retailer where they compete simultaneously under three factors including price, service and simple price discount contract. It is assumed that the second manufacturer provides service directly to his customers, and the retailer provides service for the first product's customers, while the retailer buys the first product under price discount from the first manufacturer. The analysis of the optimal equilibrium solutions and the results of the numerical examples show that if a manufacturer chooses the appropriate range of discount rate, he will gain more profit than when there is no discount given to the retailer. This situation can be considered as an effective tool for the coordination of the first manufacturer and the retailer to offer discount by manufacturer and to provide the service by the retailer. We obtain equilibrium solution of Retailer Stackelberg game and analyze the numerical examples under two cases: a) the manufacturers sell their products to the retailer without price discount contract. b) The first manufacturer sells his products to the retailer with the simple price discount contract. The preliminary results show that the service and the price discount contract can improve the performance of supply chain.

    The study is the first research in Malaysia that investigates user acceptance of Internet banking service (IBS) based on Unified Theory of Acceptance and Use of Technology model (Venkatesh, Morris, Davis and Davis, 2003). Two hundred and eighty questionnaires were distributed and collected from two major cities, Kuala Lumpur and Melaka. Descriptive statistics was used to analyse the data. The results show that Malaysians have intentions of using IBS (mean rating of close to 4.00). Moreover, Malaysians recognize the benefits of IBS by giving a high mean rating (close to 4.00) to performance expectancy. However, they give relative low mean ratings (close to 3.00) on other indicators of Behavioural Intention to Use IBS such as effort expectancy, social influence, facilitating conditions and perceived credibility. Recommendations were given to promote a safe, efficient and conducive environment for user adoption of Internet banking.

  13. Evaluating Common Privacy Vulnerabilities in Internet Service Providers

    Kotzanikolaou, Panayiotis; Maniatis, Sotirios; Nikolouzou, Eugenia; Stathopoulos, Vassilios

    Privacy in electronic communications receives increased attention in both research and industry forums, stemming from both the users' needs and from legal and regulatory requirements in national or international context. Privacy in internet-based communications heavily relies on the level of security of the Internet Service Providers (ISPs), as well as on the security awareness of the end users. This paper discusses the role of the ISP in the privacy of the communications. Based on real security audits performed in national-wide ISPs, we illustrate privacy-specific threats and vulnerabilities that many providers fail to address when implementing their security policies. We subsequently provide and discuss specific security measures that the ISPs can implement, in order to fine-tune their security policies in the context of privacy protection.

  17. Improving Service Management in the Internet of Things

    Sammarco, Chiara; Iera, Antonio

    2012-01-01

    In the Internet of Things (IoT) research arena, many efforts are devoted to adapt the existing IP standards to emerging IoT nodes. This is the direction followed by three Internet Engineering Task Force (IETF) Working Groups, which paved the way for research on IP-based constrained networks. Through a simplification of the whole TCP/IP stack, resource constrained nodes become direct interlocutors of application level entities in every point of the network. In this paper we analyze some side effects of this solution, when in the presence of large amounts of data to transmit. In particular, we conduct a performance analysis of the Constrained Application Protocol (CoAP), a widely accepted web transfer protocol for the Internet of Things, and propose a service management enhancement that improves the exploitation of the network and node resources. This is specifically thought for constrained nodes in the abovementioned conditions and proves to be able to significantly improve the node energetic performance when in the presence of large resource representations (hence, large data transmissions).

    2016-05-01

    Full Text Available Employees who abuse Internet privileges have become a major concern among today's employers. Employees misuse Internet at the workplace due to the overcrowded schedule, pressures at work, etc. Internet for private purposes is also used as a release or escape from work, escape from the reality of the workplace or due to poor organizational climate; it can be used as an efficient use of time at work but it can also be excessively used when the employees are not monitored. The survey results show that there is a correlation between Internet addiction and misuse of the Internet in the workplace. Electronic monitoring has a strong impact on the abuse of the Internet. More electronic monitoring will decrease the abuse of the internet services in the workplace and vice versa. Organizational climate, relations in the working organization, the Internet policy and demographic factors do not affect the abuse of Internet services in the workplace.

    Full Text Available The ever increasing demand of energy efficiency and the strong awareness of environment have led to the enhanced interests in green Internet of things (IoTs. How to efficiently deliver power, especially, with the smart grid based on the stability of network becomes a challenge for green IoTs. Therefore, in this paper we present a novel real-time pricing strategy based on the network stability in the green IoTs enabled smart grid. Firstly, the outage is analyzed by considering the imbalance of power supply and demand as well as the load uncertainty. Secondly, the problem of power supply with multiple-retailers is formulated as a Stackelberg game, where the optimal price can be obtained with the maximal profit for retailers and users. Thirdly, the stability of price is analyzed under the constraints. In addition, simulation results show the efficiency of the proposed strategy.

    Internet of Things (IoT) is the next wave of industry revolution that will initiate many services, such as personal health care and green energy monitoring, which people may subscribe for their convenience. Recommending IoT services to the users based on objects they own will become very crucial for the success of IoT. In this work, we introduce the concept of service recommender systems in IoT by a formal model. As a first attempt in this direction, we have proposed a hyper-graph model for IoT recommender system in which each hyper-edge connects users, objects, and services. Next, we studied the usefulness of traditional recommendation schemes and their hybrid approaches on IoT service recommendation (IoTSRS) based on existing well known metrics. The preliminary results show that existing approaches perform reasonably well but further extension is required for IoTSRS. Several challenges were discussed to point out the direction of future development in IoTSR.

    In recent years, the Internet technology has been deeply influencing recycling industry to make it more intelligent and interconnected. However, most existing papers on “Internet Recycling” neglected the problem of pricing strategy under online and offline channels for different levels of recyclers. Moreover, the effect of regional differences has been emphasized a lot in dual-channel forward supply chain, but recycling field has seldom been concerned about it. In this paper, a recycling system consisting of one recycling center and several third-party recyclers (TPR) was investigated based on traditional mode and dual-channel mode. The dual-channel reverse supply chain model is transformed from traditional mode by the introduction of online channel. It involves two recycling modes, as recycling centre for online recovery and “Recycling center+TPR” for offline recovery. By establishing pricing strategies based on Stackelberg game model, the impacts of regional differences were analysed. Finally, numerical analysis was given to illustrate the effectiveness of the pricing mechanisms and strategies.

    2012-01-01

    Activity Based Costing (ABC) is one of the new methods began appearing as a costing methodology in the 1990's. It calculates cost price by determining the usage of resources. In this study, ABC method was used for calculating cost price of remedial services in hospitals. To apply ABC method, Shahid Faghihi Hospital was selected. First, hospital units were divided into three main departments: administrative, diagnostic, and hospitalized. Second, activity centers were defined by the activity analysis method. Third, costs of administrative activity centers were allocated into diagnostic and operational departments based on the cost driver. Finally, with regard to the usage of cost objectives from services of activity centers, the cost price of medical services was calculated. The cost price from ABC method significantly differs from tariff method. In addition, high amount of indirect costs in the hospital indicates that capacities of resources are not used properly. Cost price of remedial services with tariff method is not properly calculated when compared with ABC method. ABC calculates cost price by applying suitable mechanisms but tariff method is based on the fixed price. In addition, ABC represents useful information about the amount and combination of cost price services.

    Amin, Mohammad; Hanson, Kara; Mills, Anne

    2004-06-01

    This article examines the existence of price discrimination for obstetric services in two private hospitals in Bangladesh, and considers the welfare consequences of such discrimination, i.e. whether or not price discrimination benefited the poorer users. Data on 1212 normal and caesarean section patients discharged from the two hospitals were obtained. Obstetric services were chosen because they are relatively standardised and the patient population is relatively homogeneous, so minimising the scope and scale of product differentiation due to procedure and case-mix differences. The differences between the hospital list price for delivery and actual prices paid by patients were calculated to determine the average rate of discount. The welfare consequences of price discrimination were assessed by testing the differences in mean prices paid by patients from three income groups: low, middle and high. The results suggest that two different forms of price discrimination for obstetric services occurred in both these hospitals. First, there was price discrimination according to income, with the poorer users benefiting from a higher discount rate than richer ones; and second, there was price discrimination according to social status, with three high status occupational groups (doctors, senior government officials, and large businessmen) having the highest probability of receiving some level of discount.

    Remote medical services have been expanding globally, and this is expansion is steadily increasing. It has had many positive effects, including medical access convenience, timeliness of service, and cost reduction. The speed of research and development in remote medical technology has been gradually accelerating. Therefore, it is expected to expand to enable various high-tech information and communications technology (ICT)-based remote medical services. However, the current state lacks an appropriate security framework that can resolve security issues centered on the Internet of things (IoT) environment that will be utilized significantly in telemedicine. This study developed a medical service-oriented frame work for secure remote medical services, possessing flexibility regarding new service and security elements through its service-oriented structure. First, the common architecture of remote medical services is defined. Next medical-oriented secu rity threats and requirements within the IoT environment are identified. Finally, we propose a "service-oriented security frame work for remote medical services" based on previous work and requirements for secure remote medical services in the IoT. The proposed framework is a secure framework based on service-oriented cases in the medical environment. A com parative analysis focusing on the security elements (confidentiality, integrity, availability, privacy) was conducted, and the analysis results demonstrate the security of the proposed framework for remote medical services with IoT. The proposed framework is service-oriented structure. It can support dynamic security elements in accordance with demands related to new remote medical services which will be diversely generated in the IoT environment. We anticipate that it will enable secure services to be provided that can guarantee confidentiality, integrity, and availability for all, including patients, non-patients, and medical staff.

    The emergence of competitive markets for electricity generation services is changing the way that electricity is and will be priced in the United States. This report presents the results of an analysis that focuses on two questions: (1) How are prices for competitive generation services likely to differ from regulated prices if competitive prices are based on marginal costs rather than regulated open-quotes cost-of-serviceclose quotes pricing? (2) What impacts will the competitive pricing of generation services (based on marginal costs) have on electricity consumption patterns, production costs, and the financial integrity patterns, production costs, and the financial integrity of electricity suppliers? This study is not intended to be a cost-benefit analysis of wholesale or retail competition, nor does this report include an analysis of the macroeconomic impacts of competitive electricity prices

    2013-03-01

    Internet-based mental health services increase rapidly. However, national surveys are incomplete and the consequences for such services are poorly discussed. This study describes characteristics of 60 Internet-based mental health services in Norway and Sweden and discusses their social consequences. More than half of the services were offered by voluntary organisations and targeted towards young people. Professionals answered service users' questions in 60% of the services. Eight major themes were identified. These characteristics may indicate a shift in the delivery of mental health services in both countries, and imply changes in the understanding of mental health.

    In Japan over the past few years, more attention has been focused on unnoticed solitary death in the context of an aging society and the trend toward nuclear family. A number of institutions and companies have implemented a prevention measure with digital terrestrial broadcasting telecare services for the elderly: Hokkaido University; TV-Asahi Corporation; Hitachi, Ltd; Iwamizawa City; Hokkaido Television Broadcasting Co, Ltd; and Hamanasu Information Co, Ltd. Although this system is provided free of charge as a demonstration test, determining the appropriate price for the service is required for its sustainable operation. The aim of this study was to quantify individual willingness to pay (WTP) so as to test the tenability of digital terrestrial broadcasting service for elderly telecare. We used the contingent valuation method (CVM) to estimate the WTP for this service among 305 citizens (valid response rate 76.0%) living in Japan. A questionnaire survey was conducted for people aged 18 to 100 years according to Japanese age distribution from September 2016. To elicit WTP, we adopted a double-bound dichotomous choice method to ask the respondents whether they agree or disagree with the price we offered. The median WTP for this service's monthly fee is estimated to be 431 JPY (approximately US $3.7). The finding suggests that gender (0.66, P=.01), health consciousness (1.08, P=.01), willingness to use (2.38, PWTP. We conclude that reliable WTP was elicited by CVM based on an Internet survey. Calculated median WTP for digital terrestrial broadcasting service for elderly telecare was 431 JPY (approximately US $3.7). In the analysis of factors that affect WTP, constant factors, log-bid, health consciousness, gender, see others less than one time for week, and willingness to use made positive effect to probability of acceptance. In comparison of WTP in different groups, age groups showed that WTP of the elderly group was higher than WTP of the middle age group and

    To identify the population of Internet e-cigarette vendors (IEVs) and conduct content analysis of products sold and IEVs' promotional, claims and pricing practices. Multiple sources were used to identify IEV websites, primarily complex search algorithms scanning over 180 million websites. In 2013, 32 446 websites were manually screened, identifying 980 IEVs, with the 281 most popular selected for content analysis. This methodology yielded 31 239 websites for manual screening in 2014, identifying 3096 IEVs, with 283 selected for content analysis. While the majority of IEVs (71.9%) were US based in 2013, this dropped to 64.3% in 2014 (plocated in at least 38 countries, and 12% providing location indicators reflecting two or more countries, complicating jurisdictional determinations.Reflecting the retail market, IEVs are transitioning from offering disposable and 'cigalike' e-cigarettes to larger tank and "mod" systems. Flavored e-cigarettes were available from 85.9% of IEVs in 2014, with fruit and candy flavors being most popular. Most vendors (76.5%) made health claims in 2013, dropping to 43.1% in 2014. Some IEVs featured conflicting claims about whether or not e-cigarettes aid in smoking cessation. There was wide variation in pricing, with e-cigarettes available as inexpensive as one dollar, well within the affordable range for adults and teens. The number of Internet e-cigarette vendors grew threefold from 2013 to 2014, far surpassing the number of Internet cigarette vendors (N=775) at the 2004 height of that industry. New and expanded regulations for online e-cigarette sales are needed, including restrictions on flavors and marketing claims. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    2013-03-01

    Full Text Available Purpose: With the rapid development of economy and the support of government policy, the development of the logistics industry has become a new economic growth engine. As we all know, the reasonable price of logistics service is the most critical factor for logistics enterprises to win market share and make profit. At the same time, the service level is one of the most important factors which will influence the size of the market share. Therefore, this paper constructs a pricing model considering a situation that the logistics service level affects the market demand. This model helps the enterprises to make scientific decisions.Methodology: To achieve this objective, this paper constructs the TPL service and the pricing decision models based on the game theory.Findings: The conclusion shows that under the situation of independent decision-making, the enterprise which has strong ability of logistics service does not necessarily have a competitive advantage, while pricing equilibrium under the situation of joint decision-making, not only make both sides get more income, but also be conducive to improve the level of service.Research limitations: In this research, there are some assumptions that might affect the accuracy the model such as there are only two TPL enterprises to participate in, and considerations are taken under the condition of complete information environment. These assumptions can be relaxed in the future work.Originality: In this research, logistics service level is taken account into the areas of logistics service pricing, which makes the models more practical and more perfect. And this paper constructs game models based on game theory to make up the limitations of traditional pricing theories in logistics service pricing.

  11. Energy Aware Pricing in a Three-Tiered Cloud Service Market

    Directory of Open Access Journals (Sweden)

    Debdeep Paul

    2016-09-01

    Full Text Available We consider a three-tiered cloud service market and propose an energy efficient pricing strategy in this market. Here, the end customers are served by the Software-as-a-Service (SaaS providers, who implement customized services for their customers. To host these services, these SaaS providers, in turn, lease the infrastructure related resources from the Infrastructure-as-a-Service (IaaS or Platform-as-a-Service (PaaS providers. In this paper, we propose and evaluate a mechanism for pricing between SaaS providers and Iaas/PaaS providers and between SaaS providers and the end customers. The pricing scheme is designed in a way such that the integration of renewable energy is promoted, which is a very crucial aspect of energy efficiency. Thereafter, we propose a technique to strategically provide an improved Quality of Service (QoS by deploying more resources than what is computed by the optimization procedure. This technique is based on the square root staffing law in queueing theory. We carry out numerical evaluations with real data traces on electricity price, renewable energy generation, workload, etc., in order to emulate the real dynamics of the cloud service market. We demonstrate that, under practical assumptions, the proposed technique can generate more profit for the service providers operating in the cloud service market.

  16. Distributor pricing approaches enabled in Smart Grid to differentiate delivery service quality

    Directory of Open Access Journals (Sweden)

    Zhongwei Jake Zhang

    2014-12-01

    Full Text Available Industry practitioners who advocate retail competition and Demand-side Participation now look for approaches to link both initiatives through distributor pricing. As distributors incrementally convert more traditional assets into Smart Grid assets, they also need to consider different pricing approaches to recover the investment costs and meet the regulatory business requirements. Small electricity consumers need incentives to take part in these initiatives but their delivery service quality should also be closely guarded. Hence this paper addresses the above needs as a whole and investigates a set of distributor pricing approaches with Smart Grid technologies. Pricing of network and non-network based solutions should follow the incremental basis, such as the long run average incremental cost (LRAIC. The benefit of deferring network investment is calculated and should be passed to consumers as peak pricing rebate. A concept of reliability premium (RP based on load point reliability index is proposed, through which customers can express their preference of service quality and adjust their network tariff payment accordingly. A service delivery model is also proposed to utilize the savings from wholesale market trading to compensate for the downgraded service when loads are controlled. The IEEE 123-node distribution test feeder and the IEEE distribution system for RBTS Bus No. 2 are simulated, and solved using General Algebraic Modeling System (GAMS to demonstrate the proposed distributor pricing approaches in Smart Grid.

  18. Cost and price auditing: effectiveness in the procurement of defense services in Spain

    Directory of Open Access Journals (Sweden)

    José Aguado Romero

    Full Text Available Abstract Contract auditing, or cost and price auditing, has been applied in Spain as a means of determining prices in non-competitive defense contracts since 1989. Factors such as Spain's participation in international defense organizations, the characteristics of the defense market and the contractual legal framework for the procurement of defense goods and services help underscore the need for the Spanish Ministry of Defense to implement cost and price auditing. With the evolution of cost and price auditing in Spain in mind, this paper analyses the entire process, describes the audit procedures that are most commonly used today and assesses the main results achieved, in terms of financial savings. The results obtained show that cost and price auditing does indeed contribute to a more efficient use of public resources.

    To determine the effect of reference-based pricing (RBP) on the percentage of lab services utilized by members that were at or below the reference price. Retrospective, quasi-experimental, matched, case-control pilot evaluation of an RBP benefit for lab services. The study group included employees of a multinational grocery chain covered by a national health insurance carrier and subject to RBP for lab services; it had access to an online lab shopping tool and was informed about the RBP benefit through employer communications. The reference group was covered by the same insurance carrier but not subject to RBP. The primary end point was lab compliance, defined as the percentage of lab claims with total charges at or below the reference price. Difference-in-difference regression estimation evaluated changes in lab compliance between the 2 groups. Higher compliance per lab claim was evident for the study group compared with the reference group (69% vs 57%; Ponline shopping tool was used by 7% of the matched-adjusted study group prior to obtaining lab services. Lab compliance was 76% for study group members using the online tool compared with 68% among nonusers who were subject to RBP (P<.01). RBP can promote cost-conscious selection of lab services. Access to facilities that offer services below the reference price and education about RBP improve compliance. Evaluation of the effect of RBP on higher-cost medical services, including radiology, outpatient specialty, and elective inpatient procedures, is needed.

We analyzed service provider's short and long term pricing problems in unobservable M/M/1 queues having the rational customers, where, for customers, the unit cost of waiting in the queue is higher than unit cost of waiting in the service. We showed that waiting in the queue has a clear negative effect on customers’ utilities, hence the service provider's price values. We also showed that, in the short term, monopolistic pricing is optimal for congested systems with high server utilization levels, whereas in the long term, market capturing pricing is more profitable.

    The impact of parity coverage on the quantity of behavioral health services used by enrollees and on the prices of these services was examined in a set of Federal Employees Health Benefit (FEHB) Program plans. After parity implementation, the quantity of services used in the FEHB plans declined in five service categories, compared with plans that did not have parity coverage. The decline was significant for all service types except inpatient care. Because a previous study of the FEHB Program found that total spending on behavioral health services did not increase after parity implementation, it can be inferred that average prices must have increased over the period. The finding of a decline in service use and increase in prices provides an empirical window on what might be expected after implementation of the federal parity law and the parity requirement under the health care reform law.

    Full Text Available Cost is an important measure of project success and clients will expect a reliable forecast at the early stage of construction projects to inform their business decision. This study was undertaken to investigate the current practices in managing cost of mechanical and electrical (M&E services in buildings. The perceptions of practitioners on the benefits of adopting Standard – Based Pricing Mechanism for M&E services as used for building fabrics and finishes was ascertained. The methodology adopted for the study was semi – structure interview and questionnaire survey.  Inferential statistics technique was used to analyse the data collected. The results revealed that, M&E services tender documents are often based on lump sum contract. Practitioners are of the opinion that the adoption of Standard – Based Pricing Mechanism (SBPM could enhance the quality of M&E services price forecast; ensure active post contract cost monitoring and control; encourage collaborative working relationship; enhance efficient whole life cycle cost management; improve risk management and facilitate efficient tendering process. The study suggested the development of local Standard Method of Measurement for M&E services and proposed strategies to facilitate the adoption of SBPM as basis for forecasting contract price of mechanical and electrical services in buildings.

    This paper addresses price elasticity of demand (PED) in a region where most patients make payments for consultations out of pocket. PED is a measure of the responsiveness of the quantity demanded of goods or services to changes in price. The study was done in the context of an outpatient psychiatric clinic in a sub -Saharan African country. The study was performed at the University College Hospital (UCH), Ibadan, Nigeria. Aggregate data were collected on weekly clinic attendance over a 24-month period October 2008 - September 2010 representing 12 months before, to 12months after a 67% increase in price of outpatient psychiatric consultation. The average weekly clinic attendance prior to the increase was compared to the average clinic attendance after the price increase. Arc-PED for consultation was also estimated. Clinic attendance dropped immediately and significantly in the weeks following the price increase. There was a 34.4% reduction in average weekly clinic attendance. Arc-PED for psychiatric consultation was -0.85. In comparison to reported PED on health care goods and services, this study finds a relatively high PED in psychiatric consultation following an increase in price of user fees of psychiatric consultation.

    2017-01-01

    This study addresses joint inventory control and pricing decisions for a service-inventory system. In such a system both an on-hand inventory item and a positive service time are required to fulfill customer demands. The service-inventory system also captures main features of the classical...... inventory systems with a positive processing time, e.g., make-to-order systems. In this study, the service-inventory system is modeled as an M/M/1 queue in which the customer arrival rate is price dependent. The inventory of an individual item is continuously reviewed under an (r,Q) policy....... The replenishment lead times of the inventory are exponentially distributed. Furthermore, customers arriving during stock-out periods are lost. The stochastic customer inter-arrival times, service times, and inventory replenishment lead times cause the high complexity of the problem and the difficulty in solving it...

    As the "Internet of Things" is expected to grow rapidly in the following years, the need to develop and deploy efficient and scalable Discovery Services in this context is very important for its success. Thus, the ability to evaluate and compare the performance of different Discovery Services architectures is vital if we want to allege that a given design is better at meeting requirements of a specific application. The purpose of this chapter is to provide a paradigm for the evaluation of different Discovery Services for the Internet of Things in terms of efficiency, scalability and performance through the use of simulations. The methodology presented uses the application of Discovery Services to a supply chain with the Service Lookup Service Discovery Service using OMNeT++, an open source network simulation suite. Then, we delve into the simulation design and the details of our findings.

  19. Social Norms in Water Services: Exploring the Fair Price of Water

    Directory of Open Access Journals (Sweden)

    Ossi Heino

    2015-02-01

    Full Text Available The aim of this article is to analyse price fairness in water services. Although a considerable amount of literature has been published on water pricing, these studies have mainly approached the question from instrumental and rational perspectives. Little attention has been paid to the human side of water pricing. Therefore, the general objective of this research is to shed light on these softer factors, filling the gap in knowledge of the emotional connections with water services. In this research, we explored peopleʼs ideas and views about water pricing by conducting 74 interviews in 11 municipalities in Finland. The results suggest that people are not just rational consumers of a good but also have emotional ties to water utilities and municipal decision-making. The general attitude towards a water utility is confident and sympathetic if its operations and municipal decision-making processes are considered as fair, and conversely, unsympathetic if operations and decision-making are considered unfair. This is a topical issue as many water utilities are facing pressures to increase water prices; being fair appeared to be a crucial way to gain appreciation and support through difficult times. Because fairness seems to be an emergent property of social experiences, special attention should be paid to the 'soft side' of water services.

    The aim of the article was to present and compare cost accounting models which are used in the area of healthcare for pricing purposes in different countries. Cost information generated by hospitals is further used by regulatory bodies for setting or updating prices of public health services. The article presents a set of examples from different countries of the European Union, Australia and the United States and concentrates on DRG-based payment systems as they primarily use cost information for pricing. Differences between countries concern the methodology used, as well as the data collection process and the scope of the regulations on cost accounting. The article indicates that the accuracy of the calculation is only one of the factors that determine the choice of the cost accounting methodology. Important aspects are also the selection of the reference hospitals, precise and detailed regulations and the existence of complex healthcare information systems in hospitals.

    The National Institute of Standards and Technology (NIST) is expanding into a new frontier in the delivery of measurement services. The Internet will be employed to provide industry with electronic traceability to national standards. This is a radical departure from the traditional modes of traceability and presents many new challenges. The traditional mail-based calibration service relies on sending artifacts to the user, who then mails them back to NIST for evaluation. The new service will deliver calibration results to the industry customer on-demand, in real-time, at a lower cost. The calibration results can be incorporated rapidly into the production process to ensure the highest quality manufacturing. The service would provide the US radiation processing industry with a direct link to the NIST calibration facilities and its expertise, and provide an interactive feedback process between industrial processing and the national measurement standard. Moreover, an Internet calibration system should contribute to the removal of measurement-related trade barriers

    Energy service business, or energy service company (ESCO), is expanding among industrial users as a means of energy saving. The ESCO business normally tends to become a long-term operation. During the operation, fluctuations of fuel and electricity costs significantly impact on the stability of the profit from ESCO business. Therefore, it is essential to reduce the risk of fuel and electricity cost fluctuations. Generally, a transaction called ''financial derivative'' is used as a measure of hedging against the fuel price fluctuation. In the case of ESCO business, it is necessary to manage the risk of both electricity and fuel price fluctuations because the variation in electricity price strongly affects the profit from ESCO as that in fuel price does. In this paper, the stabilization of the ESCO profit using financial derivatives was discussed by quantitative analyses of the actual data from existing plants. Case studies revealed that the appropriate volume of the fuel derivative implementation was less than a half of the fuel consumption at the ESCO facilities, and it ranged from 5% to 50%. (author)

    While Australians are searching the internet for third molar (TM) information, the usefulness of online sources may be questioned due to quality variation. This study explored: (i) internet use, online information-seeking behaviour among TM patients attending public dental services; and (ii) whether patients' TM knowledge scores are associated with the level of internet use and eHealth Literacy Scale (eHEALS) scores. Baseline survey data from the 'Engaging Patients in Decision-Making' study were used. Variables included: sociodemographics, internet access status, online information-seeking behaviour, eHEALS, the Control Preferences Scale (CPS) and TM knowledge. Participants (N = 165) were mainly female (73.8%), aged 19-25 years (42.4%) and had 'secondary school or less' education (58.4%). A majority (N = 79, 52.7%) had sought online dental information which was associated with active decisional control preference (odds ratio = 3.1, P = 0.034) and higher educational attainment (odds ratio = 2.7, P = 0.040). TM knowledge scores were not associated with either the level of internet use (F (2,152) = 2.1, P = 0.094, χ 2 = 0.0310) or the eHEALS scores (r = 0.147, P = 0.335). 'The internet-prepared patient' phenomena exists among public TM patients and was explained by preference for involvement in decision-making. However, internet use was not associated with better TM knowledge. Providing TM patients with internet guidance may be an opportunity to improve TM knowledge. © 2017 Australian Dental Association.

    2003-01-01

    PURPOSE The increasing use of the Internet to obtain genetics information and to order medical services without a prescription, combined with a rise in direct-to-consumer marketing for genetic testing, suggests the potential for the Internet to be used to sell genetic services. METHODS A systematic World Wide Web search was conducted in May 2002 to assess the availability of genetic services sold directly to consumers on the Internet. RESULTS Out of 105 sites that offered genetic services directly, most offered non-health-related services, including parentage confirmation testing (83%), identity testing (56%), and DNA banking (24%); however, health-related genetic tests were offered through 14 sites (13%). The health-related genetic tests available ranged from standard tests, such as hemochromatosis and cystic fibrosis, to more unconventional tests related to nutrition, behavior, and aging. Of these 14 sites, 5 described risks associated with the genetic services and 6 described the availability of counseling. CONCLUSIONS The availability of direct sales of health-related genetic tests creates the potential for inadequate pretest decision making, misunderstanding test results, and access to tests of questionable clinical value.

    Full Text Available The growing popularity of RFID (Radio Frequency Identification systems cannot be overlooked due to their wide range of application areas. However, some RFID applications face security and privacy threats due to the exposure of tags over wider distances. There are security methods but these can lack security and scalability when authenticating RF tags in MORIS (Multi Organizational RFID System. RFID systems operating within a single domain have only security and privacy issues due to the security method on tags, but in a multi-organizational system there are even more security and privacy issues in the system architecture rather than just in the security method on tag side. In this paper, we have designed a broker service to EPC (Electronic Product Code system architecture for secure and confidential data management of the RFID data events. Secure and confidential authentication broker service is an extension to the EPC network architecture for a MORIS. The central authentication broker service ensures to avoid illicit access to the confidential RFID tag\\'s data such as EPC code, whilst managing a large-scale authentication data to ensure secure and deterministic response to the authentic entities of the system.

    2014-07-01

    Full Text Available This article studies a supply chain composed of a manufacturer and two competing retailers. The manufacturer produces two substitutable products and offers respective service levels to customers who buy one of the two products. Each retailer can only order one kind of product from the manufacturer, and then sell them to the market at a certain sale price. The demands for two products are influenced not only by the service levels the manufacturer provides, but also the sales prices of the two products. Furthermore, we investigate the equilibrium behavior of members in the supply chain with the aid of the Stackelberg game, and discover a number of insights concerning some important parameters. Finally, Numerical analysis is presented to validate our theoretical results and compare channel performances.

    The User-Generated Service (UGS) concept allows end-users to create their own services as well as to share and manage the lifecycles of these services. The current development of the Internet-of-Things (IoT) has brought new challenges to the UGS area. Creating smart services in the IoT environment requires a dynamic social network that considers the relationship between people and things. In this paper, we consider the know-how required to best organize exchanges between users and things to enhance service composition. By surveying relevant aspects including service composition technology, social networks and a recommendation system, we present the first concept of our framework to provide recommendations for a dynamic social network-based means to organize UGSs in the IoT.

    Ogden, J R; Ogden, D T

    1992-01-01

    In the past few years there has been a decrease in governmental support of Community Mental Health centers. Because of this, there has been some concern, on the part of Community Mental Health professionals, as to the overall impact of this decreased governmental support. Research has been conducted that speculates on how best to handle this mini-crisis. One article suggests moving to an overall marketing approach to help combat this dollar support decline (Day and Ford 1988). Others provide methods for surveying Community Mental Health users (Ludke, Curry & Saywell 1983). William Winston (1988) suggests an overall psychographic segmentation approach to developing market targets. There has also been research detailing promotional methods for expanded marketing coverage (Moldenhauer 1988), however little has been written defining the pricing impact on Community Mental Health services. This study addresses the perceptions of Community Mental Health Center users toward the price variable of the marketing mix.

  13. Theories of the price and quantity of physician services. A synthesis and critique.

    Science.gov (United States)

    Farley, P J

    1986-12-01

    In the traditional neoclassical model of supply and demand, prices determine the allocation of economic resources. The difficulty in applying this model to physician services is the rationing of resources directly by physicians themselves, eliminating the allocative function of prices. Welfare consequences are appropriately judged in terms of efficiency and equity, not departures from the structural relationships implied by supply and demand. As interpreted here, both competitive theories and target-income theories of this market imply that physicians consider both their own welfare and the welfare of their patients in their decision-making. All consumer benefits and all producer costs are internalized by physicians. They consequently have an incentive to obtain the maximum possible social benefit from the resources at their disposal, to the extent that they are (implicitly) allowed to share in the resulting social gains. The distribution of gains between patients and physicians is determined by professional ethics within bounds imposed by competitive forces.

    2016-03-01

    The Internet of Things (IoT) makes it possible for us to sense the physical world and locate objects in it using the enabling technologies associated with IoT. Compared with traditional information systems, IoT enabling technologies can help acquire real-time data necessary for managing enterprise business process. An IoT system should have an ability beyond integrating enabling technologies and traditional information systems that are only used to access environmental data. This paper begins with a literature review of IoT-related issues and a discussion of the difference between traditional information service and IoT service. Three principles for IoT service design from the perceptive of service classification, coordination and compatibility are proposed. The paper also proposes a utility model for resource allocation in order to improve IoT service performance, and an application involving a cold chain visibility platform is given to illustrate our research.

  20. A DHT-Based Discovery Service for the Internet of Things

    Directory of Open Access Journals (Sweden)

    Federica Paganelli

    2012-01-01

    Full Text Available Current trends towards the Future Internet are envisaging the conception of novel services endowed with context-aware and autonomic capabilities to improve end users’ quality of life. The Internet of Things paradigm is expected to contribute towards this ambitious vision by proposing models and mechanisms enabling the creation of networks of “smart things” on a large scale. It is widely recognized that efficient mechanisms for discovering available resources and capabilities are required to realize such vision. The contribution of this work consists in a novel discovery service for the Internet of Things. The proposed solution adopts a peer-to-peer approach for guaranteeing scalability, robustness, and easy maintenance of the overall system. While most existing peer-to-peer discovery services proposed for the IoT support solely exact match queries on a single attribute (i.e., the object identifier, our solution can handle multiattribute and range queries. We defined a layered approach by distinguishing three main aspects: multiattribute indexing, range query support, peer-to-peer routing. We chose to adopt an over-DHT indexing scheme to guarantee ease of design and implementation principles. We report on the implementation of a Proof of Concept in a dangerous goods monitoring scenario, and, finally, we discuss test results for structural properties and query performance evaluation.

    Full Text Available With the overreaching acceptance of ICT in education and access to Internet occasioned by advancement in technology, this paper investigates pre-service teachers’ use of Internet in a college of education. The study was a descriptive survey. Data was collected using a researcher designed instrument tagged “Student Internet Use Scale” (SIUS. The population comprised of all NCE pre-service teachers in Alvan Ikoku Federal College of Education Owerri Nigeria. Findings show that  mobile phones remains the most widely used mode of internet access with social networking, searching for information on school assignments, chatting forming the major reasons why they surf the net. Social networking is the major purpose for Internet use by female pre-service teachers while school related activities are of priority to males. The difference in purpose of internet use according to gender is however not statistically significant; similarly, there is no statically significant difference between male and female pre-service teachers in the frequency of Internet usage. The result has far reaching implication for provision and use of Internet facilities to enhance teaching and learning in the College and colleges of education in Nigeria.

  3. Pricing Energy and Ancillary Services in a Day-Ahead Market for a Price-Taker Hydro Generating Company Using a Risk-Constrained Approach

    Directory of Open Access Journals (Sweden)

    Perica Ilak

    2014-04-01

    Full Text Available This paper analyzes a price-taker hydro generating company which participates simultaneously in day-ahead energy and ancillary services markets. An approach for deriving marginal cost curves for energy and ancillary services is proposed, taking into consideration price uncertainty and opportunity cost of water, which can later be used to determine hourly bid curves. The proposed approach combines an hourly conditional value-at-risk, probability of occurrence of automatic generation control states and an opportunity cost of water to determine energy and ancillary services marginal cost curves. The proposed approach is in a linear constraint form and is easy to implement in optimization problems. A stochastic model of the hydro-economic river basin is presented, based on the actual Vinodol hydropower system in Croatia, with a complex three-dimensional relationship between the power produced, the discharged water, and the head of associated reservoir.

  5. Proximity-Based Asynchronous Messaging Platform for Location-Based Internet of Things Service

    Directory of Open Access Journals (Sweden)

    Hyeong gon Jo

    2016-07-01

    Full Text Available The Internet of Things (IoT opens up tremendous opportunities to provide location-based applications. However, despite the services around a user being physically adjacent, common IoT platforms use a centralized structure, like a cloud-computing architecture, which transfers large amounts of data to a central server. This raises problems, such as traffic concentration, long service latency, and high communication cost. In this paper, we propose a physical distance-based asynchronous messaging platform that specializes in processing personalized data and location-based messages. The proposed system disperses traffic using a location-based message-delivery protocol, and has high stability.

    2002-01-01

    The increase within the energy and effect consumption in Norway, parallel with a small development of new power production has resulted in an increased focus on the end user flexibility. An efficient utilisation of the end user flexibility assumes that the market mechanisms are adapted/developed so that the user has economical incentives for reducing the consumption in periods with energy and effect shortage. Furthermore the technological solutions within the information and communication technology (ICT) open new possibilities for acquiring energy and effect reducing potentials at the end users. The Internet is an universal communication channel which opens new possibilities for communication between the power market and the end users. The unique properties of the internet particularly the easy access and low costs for upgrading and maintenance, makes a considerable potential for the use of new products and services which will increase the flexibility in the use of energy and effect. The report presents a survey of existing products and services which are offered on the Internet in the power sector. The report emphasises particularly on a comparison of these solutions regarding purpose, functionality, user friendliness and limitations of these products. The appendix includes a glossary of works and expressions which is related to the ICT.

    The catastrophic events like earthquakes, hurricanes or flooding are characteristics for some areas, a properly calculated annual premium would be closely as high as the loss insured. From an actuarial perspective, such events constitute the risk that are not insurable. On the other hand people living in such areas need protection. In order to securitize the catastrophe risk, futures or options based on a loss index could be considered. Chicago Board of Trade launched a new class of catastrophe insurance options based on new indices provided by Property Claim Services (PCS). The PCS-option is based on the Property Claim Service Index (PCS-Index). The index are used to determine and payout in writing index-based insurance derivatives. The objective of this paper is to price PCS Catastrophe Insurance Option based on PCS Catastrophe index. Gamma Distribution is used to estimate PCS Catastrophe index distribution.

    2017-01-01

    Full Text Available As the demands for online video services increase intensively, the selection of business models has drawn the great attention of online providers. Among them, pay-per-view mode and advertising mode are two important resource modes, where the reasonable fee charge and suitable volume of ads need to be determined. This paper establishes an analytical framework studying the optimal dynamic pricing and advertising strategies for online providers; it shows how the strategies are influenced by the videos available time and the viewers’ emotional factor. We create the two-stage strategy of revenue models involving a single fee mode and a mixed fee-free mode and find out the optimal fee charge and advertising level of online video services. According to the results, the optimal video price and ads volume dynamically vary over time. The viewer’s aversion level to advertising has direct effects on both the volume of ads and the number of viewers who have selected low-quality content. The optimal volume of ads decreases with the increase of ads-aversion coefficient, while increasing as the quality of videos increases. The results also indicate that, in the long run, a pure fee mode or free mode is the optimal strategy for online providers.

    The Internet of Things (IoT) has made it possible for devices around the world to acquire information and store it, in order to be able to use it at a later stage. However, this potential opportunity is often not exploited because of the excessively big interval between the data collection and the capability to process and analyse it. In this paper, we review the current IoT technologies, approaches and models in order to discover what challenges need to be met to make more sense of data. The main goal of this paper is to review the surveys related to IoT in order to provide well integrated and context aware intelligent services for IoT. Moreover, we present a state-of-the-art of IoT from the context aware perspective that allows the integration of IoT and social networks in the emerging Social Internet of Things (SIoT) term.

    The Internet of Things (IoT) has made it possible for devices around the world to acquire information and store it, in order to be able to use it at a later stage. However, this potential opportunity is often not exploited because of the excessively big interval between the data collection and the capability to process and analyse it. In this paper, we review the current IoT technologies, approaches and models in order to discover what challenges need to be met to make more sense of data. The main goal of this paper is to review the surveys related to IoT in order to provide well integrated and context aware intelligent services for IoT. Moreover, we present a state-of-the-art of IoT from the context aware perspective that allows the integration of IoT and social networks in the emerging Social Internet of Things (SIoT) term.

    Full Text Available The Internet of Things (IoT allows machines and devices in the world to connect with each other and generate a huge amount of data, which has a great potential to provide useful knowledge across service domains. Combining the context of IoT with semantic technologies, we can build integrated semantic systems to support semantic interoperability. In this paper, we propose an integrated semantic service platform (ISSP to support ontological models in various IoT-based service domains of a smart city. In particular, we address three main problems for providing integrated semantic services together with IoT systems: semantic discovery, dynamic semantic representation, and semantic data repository for IoT resources. To show the feasibility of the ISSP, we develop a prototype service for a smart office using the ISSP, which can provide a preset, personalized office environment by interpreting user text input via a smartphone. We also discuss a scenario to show how the ISSP-based method would help build a smart city, where services in each service domain can discover and exploit IoT resources that are wanted across domains. We expect that our method could eventually contribute to providing people in a smart city with more integrated, comprehensive services based on semantic interoperability.

    2012-11-07

    In the Internet of Things a code resolution service provides a discovery mechanism for a requester to obtain the information resources associated with a particular product code immediately. In large scale application scenarios a code resolution service faces some serious issues involving heterogeneity, big data and data ownership. A code resolution service network is required to address these issues. Firstly, a list of requirements for the network architecture and code resolution services is proposed. Secondly, in order to eliminate code resolution conflicts and code resolution overloads, a code structure is presented to create a uniform namespace for code resolution records. Thirdly, we propose a loosely coupled distributed network consisting of heterogeneous, independent; collaborating code resolution services and a SkipNet based code resolution service named SkipNet-OCRS, which not only inherits DHT’s advantages, but also supports administrative control and autonomy. For the external behaviors of SkipNet-OCRS, a novel external behavior mode named QRRA mode is proposed to enhance security and reduce requester complexity. For the internal behaviors of SkipNet-OCRS, an improved query algorithm is proposed to increase query efficiency. It is analyzed that integrating SkipNet-OCRS into our resolution service network can meet our proposed requirements. Finally, simulation experiments verify the excellent performance of SkipNet-OCRS.

    With the rapid development of the Internet of things (IoT), building IoT systems with high quality of service (QoS) has become an urgent requirement in both academia and industry. During the procedures of building IoT systems, QoS-aware service selection is an important concern, which requires the ranking of a set of functionally similar services according to their QoS values. In reality, however, it is quite expensive and even impractical to evaluate all geographically-dispersed IoT services at a single client to obtain such a ranking. Nevertheless, distributed measurement and ranking aggregation have to deal with the high dynamics of QoS values and the inconsistency of partial rankings. To address these challenges, we propose a time-aware service ranking prediction approach named TSRPred for obtaining the global ranking from the collection of partial rankings. Specifically, a pairwise comparison model is constructed to describe the relationships between different services, where the partial rankings are obtained by time series forecasting on QoS values. The comparisons of IoT services are formulated by random walks, and thus, the global ranking can be obtained by sorting the steady-state probabilities of the underlying Markov chain. Finally, the efficacy of TSRPred is validated by simulation experiments based on large-scale real-world datasets.

    2016-01-01

    Service quality to customers is an aspect that cannot be ignored in the performance assessment of water companies. Nowadays water regulators introduce awards or penalties to incentivize companies to improve service quality to customers when setting prices. In this study, the directional distance function is employed to estimate the shadow prices of variables indicating the lack of service quality to customers in the water industry i.e., written complaints, unplanned interruptions and properties below the reference level. To calculate the shadow price of each undesirable output for each water company, it is needed to ascribe a reference price for the desirable output which is the volume of water delivered. An empirical application is carried out for water companies in England and Wales. Hence, the shadow price of each undesirable output is expressed both as a percentage of the price of the desirable output and in pence per cubic meter of water delivered The estimated results indicate that on average, each additional written complaint that needs to be dealt with by the water company includes a service quality cost of 0.399p/m(3). As expected, when looking at the other service quality variables which involve network repair or replacement, these values are considerably higher. On average, the water company must spend an extra 0.622p/m(3) to prevent one unplanned interruption and 0.702p/m(3) to avoid one water pressure below the reference level. The findings of this study are of great importance for regulated companies and regulators as it has been illustrated that improvements in the service quality in terms of customer service could be challenging and therefore ongoing investments will be required to address these issues.

    Services based on the Internet of Things (IoT) technologies have emerged in various business environments. To enhance health service quality and maximize benefits, this study applied an IoT technology based on NFC and iBeacon as an omni-channel service for patient care in hospitals. Application of the IoT technology based on NFC and iBeacon was conducted in a general hospital during August 2015 through June 2016, and the development and evaluation results were aligned to an action research framework. The five phases in the action research included diagnosing, planning action, taking action, evaluating action, and specifying learning phases. During the first two phases, problems of functional operations in a hospital were diagnosed and eight service models were designed by using iBeacon and NFC to solve the problems. Service models were applied to the hospital by installing beacons, wearable beacons, beacon scanners, and NFC tags during the third phase. During the fourth and fifth phases, the roles and benefits of stakeholders participating in the service models were evaluated, and issues and knowledge of the whole application process were derived and summarized from technological, economic, social and legal perspectives, respectively. From an action research perspective, IoT-based healthcare services were developed and verified. IoT-based services enable the hospital to acquire lifelog data for precision medicine and ultimately be able to go one step closer to precision medical care. The derived service models could provide patients more enhanced healthcare services and improve the work efficiency and effectiveness of the hospital.

    To identify users' reasons to look for physician consultation on the internet instead of visiting a physician and to explore their general characteristics, motivation, and satisfaction with internet medical consultation service 'Your Questions.' Users of a free internet medical consultation service 'Your Questions' (www.plivazdravlje.hr) were invited to participate in a web-based survey designed to explore their general characteristics (age, sex, etc), reasons for using the service, the nature of their health problem or question, and their satisfaction with the service. Respondents were divided into two groups: users who consulted an internet physician only (Group I) and users who used internet consulting before or after visiting a physician (Group II). The response rate was 38% (1036/2747), with 79% female respondents. A fifth of the respondents (21%) consulted an internet physician only (Group I). Multivariate analysis revealed that the respondents in Group I were younger (median 24 vs 28 years in Group II), more interested into questions about pregnancy (odds ratio [OR], 1.984; 95% confidence interval [CI], 1.203-3.272), more often embarrassed to talk to a physician in person (OR, 1.828; 95% CI, 1.119-2.989), and more motivated to protect their privacy (OR, 1.727; 95% CI, 1.252-2.380). They also had greater satisfaction with the service (77% vs 60%, Pinternet-based medical consultation services were younger age, need for privacy protection, avoidance of embarrassment at the physician's office, and having a question related to pregnancy. This reveals the internet medical consultation service as a useful health promotion supplement that is particularly applicable for the population of young adults.

    2017-08-01

    Full Text Available To solve the problem of solar abandoning, which is accompanied by the rapid development of photovoltaic (PV power generation, a demonstration of a photovoltaic-battery energy storage system (PV-BESS power plant has been constructed in Qinghai province in China. However, it is difficult for the PV-BESS power plant to survive and develop with the current electricity price mechanism and subsidy policy. In this paper, a three-part electricity price mechanism is proposed based on a deep analysis of the construction and operation costs and economic income. The on-grid electricity price is divided into three parts: the capacity price, graded electricity price, and ancillary service price. First, to ensure that the investment of the PV-BESS power plant would achieve the industry benchmark income, the capacity price and benchmark electricity price are calculated using the discounted cash flow method. Then, the graded electricity price is calculated according to the grade of the quality of grid-connected power. Finally, the ancillary service price is calculated based on the graded electricity price and ancillary service compensation. The case studies verify the validity of the three-part electricity price mechanism. The verification shows that the three-part electricity price mechanism can help PV-BESS power plants to obtain good economic returns, which can promote the development of PV-BESS power plants.

    2017-11-01

    The aim of our study was to investigate Internet and eHealth usage, with respect to eHealth literacy, by cancer patients and their relatives. Using a standardized questionnaire we asked patients who attended lectures on complementary medicine in 2016. We received 142 questionnaires. The frequency of general Internet usage was directly associated with younger age and better Internet connection. Younger participants were not only more confident in allocating health-related Internet information into reliable or unreliable facts, but also more confident and capable of gaining medical knowledge through eHealth services. A regular use of eHealth services facilitated the decision-making process. Reading ability was associated with a better understanding regarding eHealth offers. In a modern health care system, emphasis should be on skills contributing to eHealth literacy among patients to improve their ability to profit from eHealth offers and improve health care.

  1. A Web Service Protocol Realizing Interoperable Internet of Things Tasking Capability

    Science.gov (United States)

    Huang, Chih-Yuan; Wu, Cheng-Hung

    2016-01-01

    The Internet of Things (IoT) is an infrastructure that interconnects uniquely-identifiable devices using the Internet. By interconnecting everyday appliances, various monitoring, and physical mashup applications can be constructed to improve human’s daily life. In general, IoT devices provide two main capabilities: sensing and tasking capabilities. While the sensing capability is similar to the World-Wide Sensor Web, this research focuses on the tasking capability. However, currently, IoT devices created by different manufacturers follow different proprietary protocols and are locked in many closed ecosystems. This heterogeneity issue impedes the interconnection between IoT devices and damages the potential of the IoT. To address this issue, this research aims at proposing an interoperable solution called tasking capability description that allows users to control different IoT devices using a uniform web service interface. This paper demonstrates the contribution of the proposed solution by interconnecting different IoT devices for different applications. In addition, the proposed solution is integrated with the OGC SensorThings API standard, which is a Web service standard defined for the IoT sensing capability. Consequently, the Extended SensorThings API can realize both IoT sensing and tasking capabilities in an integrated and interoperable manner. PMID:27589759

    Full Text Available The development of the Internet of Things (IoT is closely related to a considerable increase in the number and variety of devices connected to the Internet. Sensors have become a regular component of our environment, as well as smart phones and other devices that continuously collect data about our lives even without our intervention. With such connected devices, a broad range of applications has been developed and deployed, including those dealing with massive volumes of data. In this paper, we introduce a Distributed Data Service (DDS to collect and process data for IoT environments. One central goal of this DDS is to enable multiple and distinct IoT middleware systems to share common data services from a loosely-coupled provider. In this context, we propose a new specification of functionalities for a DDS and the conception of the corresponding techniques for collecting, filtering and storing data conveniently and efficiently in this environment. Another contribution is a data aggregation component that is proposed to support efficient real-time data querying. To validate its data collecting and querying functionalities and performance, the proposed DDS is evaluated in two case studies regarding a simulated smart home system, the first case devoted to evaluating data collection and aggregation when the DDS is interacting with the UIoT middleware, and the second aimed at comparing the DDS data collection with this same functionality implemented within the Kaa middleware.

    Full Text Available In this high-tech era, there have been tremendous advances in tech-based products and services. Internet is one of them that have widened the world’s eyes to a new borderless marketplace. High competition among internet service providers has pushed companies to create competitive advantage and brilliant marketing strategies. They undertake positioning mapping to describe product or service’s positioning amongst many competitors. The right positioning strategy becomes a powerful weapon to win in the battle. This research is designed to create positioning mapping based on perceptual mapping. The researcher uses Multidimensional Scaling and image mapping to achieve this research goal. Sampling is using non-probability sampling in Jakarta. Based on non-attribute approach, the research findings show that there is similarity between two different brands. Thus, both brands are competing against one another. On the other hand, CBN and Netzap provider reflect some differences to others. And some brands require some improvements in terms of network reliability.

While the sensing capability is similar to the World-Wide Sensor Web, this research focuses on the tasking capability. However, currently, IoT devices created by different manufacturers follow different proprietary protocols and are locked in many closed ecosystems. This heterogeneity issue impedes the interconnection between IoT devices and damages the potential of the IoT. To address this issue, this research aims at proposing an interoperable solution called tasking capability description that allows users to control different IoT devices using a uniform web service interface. This paper demonstrates the contribution of the proposed solution by interconnecting different IoT devices for different applications. In addition, the proposed solution is integrated with the OGC SensorThings API standard, which is a Web service standard defined for the IoT sensing capability. Consequently, the Extended SensorThings API can realize both IoT sensing and tasking capabilities in an integrated and interoperable manner.

    Dynamic pricing is the dynamic adjustment of prices to consumers depending on the value these customers attribute to a good. Underlying the concept of dynamic pricing is what marketers call price customization. Price customization is the charging of different prices to end consumers based on a discriminatory variable. Internet technology will serve as a great enabling tool for making dynamic pricing accessible to many industries.

    Companies generally have set prices on the Internet in two ways. Many start-ups have offered untenably low prices in a rush to capture first-mover advantage. Many incumbents have simply charged the same prices on-line as they do off-line. Either way, companies are missing a big opportunity. The fundamental value of the Internet lies not in lowering prices or making them consistent but in optimizing them. After all, if it's easy for customers to compare prices on the Internet, it's also easy for companies to track customers' behavior and adjust prices accordingly. The Net lets companies optimize prices in three ways. First, it lets them set and announce prices with greater precision. Different prices can be tested easily, and customers' responses can be collected instantly. Companies can set the most profitable prices, and they can tap into previously hidden customer demand. Second, because it's so easy to change prices on the Internet, companies can adjust prices in response to even small fluctuations in market conditions, customer demand, or competitors' behavior. Third, companies can use the clickstream data and purchase histories that it collects through the Internet to segment customers quickly. Then it can offer segment-specific prices or promotions immediately. By taking full advantage of the unique possibilities afforded by the Internet to set prices with precision, adapt to changing circumstances quickly, and segment customers accurately, companies can get their pricing right. It's one of the ultimate drivers of e-business success.

    Internet sites with comparisons of prices for electricity and natural gas appear to be important tools for consumers. On a regular basis the Dutch Office of Energy Regulation (DTe) carries out a study on the quality of such price comparison sites. In this report the results of the June 2007 study are summarized. [Dutch] Voor een goedwerkende markt is een goed geinformeerde consument van belang. Uit de Consumentenmonitor, kwalitatief onderzoek dat de NMa in 2006 heeft laten uitvoeren, is gebleken dat de consument bij een overstap vaak gebruik maakt van prijsvergelijkingssites. Het belang van dergelijke sites neemt alleen maar toe. Door een grotere differentiatie aan producten en meer variatie in prijsstelling wordt een goede vergelijking van energieleveranciers voor de gemiddelde consument steeds lastiger. Ook voor de prijsvergelijkingssites neemt de complexiteit toe. De Directie Toezicht Energie (DTe) van de Nederlandse Mededingingsautoriteit (NMa) onderzoekt sinds 2004 jaarlijks de kwaliteit van (prijs)vergelijkingssites voor elektriciteit en gas. Gezien de groeiende complexiteit van de prijsvergelijkingen is het van belang dat de NMa dit onderzoek ook in 2007 uitvoert. In dit rapport worden de resultaten van dit jaar gepresenteerd. Daarnaast heeft de NMa voor het eerst een handleiding met tips voor de consument als bijlage bij dit rapport opgenomen.

    2001-12-01

    Universities across the nation are transforming their teaching and research efforts through increased use of a rapidly expanding menu of environmental data. With funding from the Division of Atmospheric Sciences (ATM ) of the National Science Foundation (NSF), the Unidata Program is playing a central role in this transformation by enabling universities to employ innovative computing and networking technologies to acquire such data sets in real-time and use them routinely in their classrooms and research labs. Working with the Unidata Program Center (UPC), the Unidata community, comprising over 140 departments, has built a national Internet Data Distribution (IDD ) system. The IDD allows users to "subscribe" to certain sets of data products; IDD servers then deliver the requested data to their local servers as soon as they are available from the source. With the initial national implementation in 1994, the IDD may have been the original example of Internet "push" technology. It now provides the reliability, flexibility, and efficiency required by participating institutions. As the underlying Internet technology evolves, we anticipate dramatic increases in the volume of data delivered. We plan to augment the system to better serve disciplines outside the atmospheric sciences and to incorporate anticipated new networking technologies to minimize the impact of the IDD on the underlying network. Unidata has recently undertaken a new initiative called THREDDS (THematic Real-time Environmental Distributed Data Services) under a grant from the NSF Division of Undergraduate Education NSDL (National Science, Math, Engineering, Technology Education Digital Library). The goal of THREDDs is to make it possible for students, educators and researchers to publish, contribute, find, and interact with data relating to the Earth system in a convenient, effective, and integrated fashion. Just as the World Wide Web and digital-library technologies have simplified the process of

    Full Text Available Introduction: Internet-based guided self-help and face-to-face CBT have shown to be effective in the treatment of depression, but both approaches might not be an available treatment option for all patients. A treatment which blends internet-based guided self-help with video-based psychotherapy might reduce potential disadvantages of both approaches, while maintaining major advantages such as being location-independent. Additionally, it could provide a stronger focus on patient empowerment and lower resource use compared to traditional face-to-face treatment. Aim: The aim of this study is to evaluate patient's experiences with blended internet- and video-based CBT (blended iCBT treatment and to derive suggestions for the improvement of such services. Methods: Semi-structured interviews were conducted with 15 participants of the blended iCBT treatment as part of the European MasterMind trial. Participants included adults suffering from Major Depressive Disorder. The interview guide assessed patient's experiences regarding the four treatment components program, 1. face-to-face diagnostic interviews, 2. video-based synchronous therapy sessions (VTS, 3. online self-help treatment modules (OTM as well as 4. behaviour diaries and symptom monitoring. Interviews were analyzed using the framework method and outcomes regarding connections within and between participants and categories were generated by counting the statements within relevant themes. Results: Overall, patients indicated to have been satisfied with all components of the treatment, highlighting the option to independently work from home in their own pace. While the OTMs allowed for a deeper reflection of the content, the VTS with the therapist were mentioned to provide the personal character of the service. The working alliance with the therapist was experienced as fostering the individual fit of the treatment. Patients reported a high self-perceived treatment effectiveness. Negative effects

  18. Strategy and the Internet.

    Porter, M E

    2001-03-01

    Many of the pioneers of Internet business, both dot-coms and established companies, have competed in ways that violate nearly every precept of good strategy. Rather than focus on profits, they have chased customers indiscriminately through discounting, channel incentives, and advertising. Rather than concentrate on delivering value that earns an attractive price from customers, they have pursued indirect revenues such as advertising and click-through fees. Rather than make trade-offs, they have rushed to offer every conceivable product or service. It did not have to be this way--and it does not have to be in the future. When it comes to reinforcing a distinctive strategy, Michael Porter argues, the Internet provides a better technological platform than previous generations of IT. Gaining competitive advantage does not require a radically new approach to business; it requires building on the proven principles of effective strategy. Porter argues that, contrary to recent thought, the Internet is not disruptive to most existing industries and established companies. It rarely nullifies important sources of competitive advantage in an industry; it often makes them even more valuable. And as all companies embrace Internet technology, the Internet itself will be neutralized as a source of advantage. Robust competitive advantages will arise instead from traditional strengths such as unique products, proprietary content, and distinctive physical activities. Internet technology may be able to fortify those advantages, but it is unlikely to supplant them. Porter debunks such Internet myths as first-mover advantage, the power of virtual companies, and the multiplying rewards of network effects. He disentangles the distorted signals from the marketplace, explains why the Internet complements rather than cannibalizes existing ways of doing business, and outlines strategic imperatives for dot-coms and traditional companies.

  19. A Framework for Exploiting Internet of Things for Context-Aware Trust-Based Personalized Services

    Full Text Available In the last years, we have witnessed the introduction of the Internet of Things (IoT as an integral part of the Internet with billions of interconnected and addressable everyday objects. On one hand, these objects generate a massive volume of data that can be exploited to gain useful insights into our day-to-day needs. On the other hand, context-aware recommender systems (CARSs are intelligent systems that assist users to make service consumption choices that satisfy their preferences based on their contextual situations. However, one of the key challenges facing the development and deployment of CARSs is the lack of functionality for providing dynamic and reliable context information required by the recommendation decision process. Thus, data obtained from IoT objects and other sources can be exploited to build CARSs that satisfy users’ preferences, improve quality of experience, and boost recommendation accuracy. This article describes various components of a conceptual IoT-based framework for context-aware personalized recommendations. The framework addresses the weakness whereby CARSs rely on static and limited contexts from user’s mobile phone by providing additional components for reliable and dynamic context information, using IoT context sources. The core of the framework consists of a context classification and reasoning management and a dynamic user profile model, incorporating trust to improve the accuracy of context-aware personalized recommendations. Experimental evaluations show that incorporating context and trust into personalized recommendation process can improve accuracy.

    Full Text Available The Internet of Things (IoT has made it possible for devices around the world to acquire information and store it, in order to be able to use it at a later stage. However, this potential opportunity is often not exploited because of the excessively big interval between the data collection and the capability to process and analyse it. In this paper, we review the current IoT technologies, approaches and models in order to discover what challenges need to be met to make more sense of data. The main goal of this paper is to review the surveys related to IoT in order to provide well integrated and context aware intelligent services for IoT. Moreover, we present a state-of-the-art of IoT from the context aware perspective that allows the integration of IoT and social networks in the emerging Social Internet of Things (SIoT term.

    Full Text Available Many patients and health care professionals in the developed world are uncomfortable about doing nothing in the face of the glaring inequities in health care between their own environment and that of Africa. In an effort to 'think global, act local' a Scottish GP practice used personal contacts to build a twinning link with a clinic serving a township in Malawi. This article describes the experience of establishing e-mail and internet services for Malawian health care staff to afford them the same level of access as developed world staff enjoy in accessing educational materials and professional supports. Using our twin link as an exemplar we are now matching other Scottish General Practices to Malawian Clinics around a common theme of modern communication media.

    Background In Japan over the past few years, more attention has been focused on unnoticed solitary death in the context of an aging society and the trend toward nuclear family. A number of institutions and companies have implemented a prevention measure with digital terrestrial broadcasting telecare services for the elderly: Hokkaido University; TV-Asahi Corporation; Hitachi, Ltd; Iwamizawa City; Hokkaido Television Broadcasting Co, Ltd; and Hamanasu Information Co, Ltd. Although this system is provided free of charge as a demonstration test, determining the appropriate price for the service is required for its sustainable operation. Objective The aim of this study was to quantify individual willingness to pay (WTP) so as to test the tenability of digital terrestrial broadcasting service for elderly telecare. Methods We used the contingent valuation method (CVM) to estimate the WTP for this service among 305 citizens (valid response rate 76.0%) living in Japan. A questionnaire survey was conducted for people aged 18 to 100 years according to Japanese age distribution from September 2016. To elicit WTP, we adopted a double-bound dichotomous choice method to ask the respondents whether they agree or disagree with the price we offered. Results The median WTP for this service’s monthly fee is estimated to be 431 JPY (approximately US $3.7). The finding suggests that gender (0.66, P=.01), health consciousness (1.08, P=.01), willingness to use (2.38, PCalculated median WTP for digital terrestrial broadcasting service for elderly telecare was 431 JPY (approximately US $3.7). In the analysis of factors that affect WTP, constant factors, log-bid, health consciousness, gender, see others less than one time for week, and willingness to use made positive effect to probability of acceptance. In comparison of WTP in different groups, age groups showed that WTP of the elderly group was higher than WTP of the middle age group and younger age group. However, WTP surveys need to

    Concerns about security on Internet of Things (IoT) cover data privacy and integrity, access control, and availability. IoT abuse in distributed denial of service attacks is a major issue, as typical IoT devices' limited computing, communications, and power resources are prioritized in implementing functionality rather than security features. Incidents involving attacks have been reported, but without clear characterization and evaluation of threats and impacts. The main purpose of this work is to methodically assess the possible impacts of a specific class-amplified reflection distributed denial of service attacks (AR-DDoS)-against IoT. The novel approach used to empirically examine the threat represented by running the attack over a controlled environment, with IoT devices, considered the perspective of an attacker. The methodology used in tests includes that perspective, and actively prospects vulnerabilities in computer systems. This methodology defines standardized procedures for tool-independent vulnerability assessment based on strategy, and the decision flows during execution of penetration tests (pentests). After validation in different scenarios, the methodology was applied in amplified reflection distributed denial of service (AR-DDoS) attack threat assessment. Results show that, according to attack intensity, AR-DDoS saturates reflector infrastructure. Therefore, concerns about AR-DDoS are founded, but expected impact on abused IoT infrastructure and devices will be possibly as hard as on final victims.

    In 1998 the Swedish noncommercial public health service Infomedica opened an Ask the Doctor service on its Internet portal. At no charge, anyone with Internet access can use this service to ask questions about personal health-related and disease-related matters. To study why individuals choose to consult previously-unknown doctors on the Internet. Between November 1, 2001, and January 31, 2002 a Web survey of the 3622 Ask the Doctor service users, 1036 men (29%) and 2586 (71%) women, was conducted. We excluded 186 queries from users. The results are based on quantitative and qualitative analysis of the answers to the question "Why did you choose to ask a question at Infomedica's 'Ask the Doctor' service?" 1223 surveys were completed (response rate 36 %). Of the participants in the survey 322 (26%) were male and 901 (74%) female. As major reasons for choosing to consult previously-unknown doctors on the Internet participants indicated: convenience (52%), anonymity (36%), "doctors too busy" (21%), difficult to find time to visit a doctor (16%), difficulty to get an appointment (13%), feeling uncomfortable when seeing a doctor (9%), and not being able to afford a doctors' visit (3%). Further motives elicited through a qualitative analysis of free-text answers were: seeking a second opinion, discontent with previous doctors and a wish for a primary evaluation of a medical problem, asking embarrassing or sensitive questions, seeking information on behalf of relatives, preferring written communication, and (from responses by expatriates, travelers, and others) living far away from regular health care. We found that that an Internet based Ask the Doctor service is primarily consulted because it is convenient, but it may also be of value for individuals with needs that regular health care services have not been able to meet.

    International health organizations and officials are bracing for a pandemic. Although the 2003 severe acute respiratory syndrome (SARS) outbreak in Toronto did not reach such a level, it created a unique opportunity to identify the optimal use of the Internet to promote communication with the public and to preserve health services during an epidemic. The aim of the study was to explore patients' attitudes regarding the health services that might be provided through the Internet to supplement those traditionally available in the event of a future mass emergency situation. We conducted "mask-to-mask" surveys of patients at three major teaching hospitals in Toronto during the second outbreak of SARS. Patients were surveyed at the hospital entrances and selected clinics. Descriptive statistics and logistic regression models were used for the analysis. In total, 1019 of 1130 patients responded to the survey (90% overall response rate). With respect to Internet use, 70% (711/1019) used the Internet by themselves and 57% (578/1019) with the help of a friend or family member. Of the Internet users, 68% (485/711) had already searched the World Wide Web for health information, and 75% (533/711) were interested in communicating with health professionals using the Internet as part of their ongoing care. Internet users expressed interest in using the Web for the following reasons: to learn about their health condition through patient education materials (84%), to obtain information about the status of their clinic appointments (83%), to send feedback to the hospital about how to improve its services (77%), to access screening tools to help determine if they were potentially affected by the infectious agent responsible for the outbreak (77%), to renew prescriptions (75%), to consult with their health professional about nonurgent matters (75%), and to access laboratory test results (75%). Regression results showed that younger age, higher education, and English as a first

    The Connexion by BoeingSM (CbB) global network will provide broadband information services to aircraft passengers and crews. Through this Ku-band (14 GHz (uplink) and 11/12 GHz (downlink)) satellite-based system, aircraft passengers and crew will no longer be limited to pre-packaged services, but instead will be able to access the full range of broadband services from their seats using their laptop, PDA or the on-board IFE console.The kind of services offered to passengers are based on the internet/intranet access via their own laptops and PDA (using Ethernet wired cable, or wireless 802.11b access), while those offered to the crew can range between various crew application (such as weather updates and travel information) and aircraft health monitoring.The CbB system is divided into four basic layers of infrastructure:(1) an airborne segment, i.e. the Aircraft Earth Station (AES) consisting of proprietary high gain antenna, transceivers and other on-board subsystems providing a nominal return link data rate of 1 Mbps and a forward link data rates up to 20 Mbps;(2) a space segment consisting of leased satellite transponders on existing in-orbit Geostationary satellites;(3) a ground segment consisting of one or more leased satellite land earth stations (LESs) and redundant interconnection facilities; and;(4) a network operations centre (NOC) segment.During 2003, trials with Lufthansa (DLH) and British Airways (BA) have proved very successful. This has resulted in the recent signing of an agreement with Lufthansa which calls for the Connexion by BoeingSM service to be installed on Lufthansa's fleet of approximately 80 long-haul aircraft, including Boeing 747-400 and Airbus A330 and A340 aircraft, beginning in early 2004. BA is expected to follow soon. In addition to the successful recent service demonstrations, both Japan Airlines (JAL) and Scandinavian Airlines System (SAS) have announced their intent to install the revolutionary service on their long-range aircraft.

    Previous studies on problematic Internet use have focused almost exclusively on the fact that presence of negative functioning, such as social anxiety, depressive symptoms, or loneliness, represents a risk factor for unhealthy use of the web. For this reason the aim of the present study was to investigate the association between psychological well-being dimensions and problematic use of Internet communicative services. In the current study 495 undergraduate students were recruited. The Italian adaptations of the Psychological Well-being Scales and the Generalized Problematic Internet Use Scale 2 (GPIUS2) were used to assess psychological well-being dimensions and generalized problematic Internet use, respectively. Psychological well-being dimensions explained a significant portion of variance for the GPIUS2 total score levels, after controlling for sex, age, and occupational status. The levels of Autonomy, Environmental Mastery, and Positive Relations with Others acted as significant negative predictors of the tendency to use the web for regulating negative feelings, compulsive use of the web, and the negative outcomes that can arise as a result. The overall findings of the present study provide preliminary evidence that low psychological well-being is associated with problematic use of Internet communicative services.

    In this paper, we focus on a dynamic spectrum access strategy for Internet of Things (IoT) applications in two types of radio systems: cellular networks and cognitive radio-enabled low power wide area networks (CR-LPWANs). The spectrum channel contention between the licensed cellular networks and the unlicensed CR-LPWANs, which work with them, only takes place within the cellular radio spectrum range. Our aim is to maximize the spectrum capacity for the unlicensed users while ensuring that it never interferes with the licensed network. Therefore, in this paper we propose a dynamic spectrum access strategy for CR-LPWANs operating in both licensed and unlicensed bands. The simulation and the numerical analysis by using a matrix geometric approach for the strategy are presented. Finally, we obtain the blocking probability of the licensed users, the mean dwell time of the unlicensed user, and the total carried traffic and combined service quality for the licensed and unlicensed users. The results show that the proposed strategy can maximize the spectrum capacity for the unlicensed users using IoT applications as well as keep the service quality of the licensed users independent of them.

  18. Study the Effect of Value-Added of Services Sector on Forecasting of Electricity Demand in Services Sector due to Price Reform

    2016-07-01

    Full Text Available Electrical energy is as one of the important effective factors on economic growth and development. In recent decades, numerous studies in different countries to estimate and forecast electricity demand in different parts of the economy have been made. In this paper, using the method ARDL, estimation and forecasting of electricity demand in the services sector of Iran are determined for the time period from 1983 to 2012. Estimated equations show that the added value of the services sector and a significant positive impact on the demand for electricity in this sector. The price elasticity for services sector is smaller than 1 due to low electricity prices and subsidized electricity. Hence, electricity prices have little impact on the demand for electricity. The results of the estimate represents a long-term relationship between the variables in the services sector. In this paper, based on amendments to the law on subsidies and estimated values, anticipated electricity demand until the end of the fifth development plan was carried out. The results indicate an increase in power consumption in the services sector.

  19. A framework for cost-based pricing of transmission and ancillary services in competitive electric power markets

    Zobian, A.; Ilic, M.D.

    1995-01-01

    In this paper the authors propose a framework for accurate cost determination and pricing of transmission and ancillary services in competitive electric power markets. The proposed framework is based on their anticipation of the evolving environment and industry structure. They envision the future as a competitive energy market with a centralized control entity that coordinates system activities, prices transmission and ancillary services and controls various system resources. This control entity has control over a certain (pre-defined) geographical area. It is proposed that the system operation and control be kept as they are currently done in control centers, no major change in these functions is required for the proposed pricing strategy. The pricing strategy is divided into two main classes based on time scale separation and firmness, short and long term, firm and interruptible contracts. The approach is based on superposition of different transaction on the network, and a three-part tariff design. The charges are directly related to the impact of each transaction on the system

    This workshop was convened to explore what is currently being done in the area of data dissemination via the Internet and to examine ways that future activities in this area within the U.S. nuclear data programs can be better coordinated. Overview talks on the current status, from both the national and international perspectives, were provided. Following these, there were presentations on specific activities in the area of Internet data dissemination which are taking place at seven different institutions. Institutions represented at this meeting were asked to provide written summaries of their programs before the meeting. The talks included actual demonstrations of the electronic methodologies which are under development at these laboratories, and they highlighted the richness and creativity of these programs. This information proved to be very useful in the ensuing general discussions. The main issues that were addressed at this meeting were: (i) how to adapt to rapid evolution of data management and dissemination technologies, (ii) how to provide outside users with some sense of unity in the U.S. nuclear data program and to develop consistent, user-friendly ways to access data without discouraging individual initiatives and the richness which comes from diversity, (iii) how to maintain quality control over the information and services provided, (iv) how to progress in a era of very restrictive budgets, (v) how to effectively merge the nuclear structure and nuclear reaction data dissemination activities while at the same time recognizing and respecting their inherent differences, (vi) how to organize the stewardship of nuclear data and the processes of nuclear data dissemination in an efficient, technically advanced and yet cost effective manner, and (vii) how the data processing tasks should be allocated between server and client computers

    2012-10-01

    Full Text Available Public authorities and national healthcare service providers across the European Union and beyond are increasingly under pressure to deliver better services with diminishing resources. Users, quite rightly, demand a high standard of service and increasingly also convenience focused on the needs of the users rather than how the services are organised to deliver them. Users, on the whole, also prefer to be supported in their homes, and be free to move as much as possible. While users without impairments and generally well provided for, there are increasingly also users who have special needs, including the aged and those with a range of physical and mental disabilities who are unable to make effective use of such services from their homes due to the lack of proactive and accessible services. The idea we promote in the chapter is to provide better support to users with disabilities and impairments from the comfort of their home by means of providing them with a set of scalable services which can be either offered for free or purchased through some central form of a marketplace repository.

    Demand response (DR) has been broadly recognized to be an integral component of well-functioning electricity markets, although currently underdeveloped in most regions. Among the various initiatives undertaken to remedy this deficiency, public utility commissions (PUC) and utilities have considered implementing dynamic pricing tariffs, such as real-time pricing (RTP), and other retail pricing mechanisms that communicate an incentive for electricity consumers to reduce their usage during periods of high generation supply costs or system reliability contingencies. Efforts to introduce DR into retail electricity markets confront a range of basic policy issues. First, a fundamental issue in any market context is how to organize the process for developing and implementing DR mechanisms in a manner that facilitates productive participation by affected stakeholder groups. Second, in regions with retail choice, policymakers and stakeholders face the threshold question of whether it is appropriate for utilities to offer a range of dynamic pricing tariffs and DR programs, or just ''plain vanilla'' default service. Although positions on this issue may be based primarily on principle, two empirical questions may have some bearing--namely, what level of price response can be expected through the competitive retail market, and whether establishing RTP as the default service is likely to result in an appreciable level of DR? Third, if utilities are to have a direct role in developing DR, what types of retail pricing mechanisms are most appropriate and likely to have the desired policy impact (e.g., RTP, other dynamic pricing options, DR programs, or some combination)? Given a decision to develop utility RTP tariffs, three basic implementation issues require attention. First, should it be a default or optional tariff, and for which customer classes? Second, what types of tariff design is most appropriate, given prevailing policy objectives, wholesale market

    2016-03-11

    The Internet of Things (IoT) is becoming increasingly important in several fields of industrial applications and personal applications, such as medical e-health, smart cities, etc. The research into protocols and security aspects related to this area is continuously advancing in making these networks more reliable and secure, taking into account these aspects by design. Bootstrapping is a procedure by which a user obtains key material and configuration information, among other parameters, to operate as an authenticated party in a security domain. Until now solutions have focused on re-using security protocols that were not developed for IoT constraints. For this reason, in this work we propose a design and implementation of a lightweight bootstrapping service for IoT networks that leverages one of the application protocols used in IoT : Constrained Application Protocol (CoAP). Additionally, in order to provide flexibility, scalability, support for large scale deployment, accountability and identity federation, our design uses technologies such as the Extensible Authentication Protocol (EAP) and Authentication Authorization and Accounting (AAA). We have named this service CoAP-EAP. First, we review the state of the art in the field of bootstrapping and specifically for IoT. Second, we detail the bootstrapping service: the architecture with entities and interfaces and the flow operation. Third, we obtain performance measurements of CoAP-EAP (bootstrapping time, memory footprint, message processing time, message length and energy consumption) and compare them with PANATIKI. The most significant and constrained representative of the bootstrapping solutions related with CoAP-EAP. As we will show, our solution provides significant improvements, mainly due to an important reduction of the message length.

    This paper proposes a new model for understanding the adoption of internet services when competing technological standards can fulfil similar needs. Using prospect theory as its theoretical foundation, the model posits that reference prices, flat rate preference, and status quo bias constitute...... the perceived sacrifice when users consider adoption of new services such as wireless internet. Perceived sacrifice and perceived quality influence the perceived relative value, which in turn influences the intention to adopt wireless internet.

  8. Bandwidth allocation and pricing problem for a duopoly market

    2011-01-01

    Full Text Available This research discusses the Internet service provider (ISP bandwidth allocation and pricing problems for a duopoly bandwidth market with two competitive ISPs. According to the contracts between Internet subscribers and ISPs, Internet subscribers can enjoy their services up to their contracted bandwidth limits. However, in reality, many subscribers may experience the facts that their on-line requests are denied or their connection speeds are far below their contracted speed limits. One of the reasons is that ISPs accept too many subscribers as their subscribers. To avoid this problem, ISPs can set limits for their subscribers to enhance their service qualities. This paper develops constrained nonlinear programming to deal with this problem for two competitive ISPs. The condition for reaching the equilibrium between the two competitive firms is derived. The market equilibrium price and bandwidth resource allocations are derived as closed form solutions.

    To evaluate and update the previously quantified effects of management, marketing, and certified health programs on the sale price of beef calves sold through a livestock video auction service. Longitudinal study. 41,657 lots representing 5,042,272 beef calves sold from 1995 through 2009. Data describing each lot of beef calves marketed from 1995 through 2009 by a livestock video auction service were obtained from sale catalogues. For each year of the study, multiple regression analysis was used to quantify the effect of management, marketing, and certified health programs on sale price. Sale date, base sale weight, quadratic effect of base weight, sex of calf, region of origin, breed description, inclusion in a certified health program, and number of calves in the lot significantly affected sale price for every year of the study. Variation in body weight, flesh score, and number of days between sale and delivery date had significant effects on price in most of the years; frame score and calves with horns affected price in 7 of 15 years; age and source verification influenced sale price in every year since source verification was introduced in 2005; and the auction service's progressive genetics program increased price during the 1 year that program was available. Some management, marketing, and certified health initiatives have consistently increased the sale price of beef calves, and producers can increase the price of their calves by implementing these practices.

    Despite caring for large numbers of older adults, prehospital emergency medical services (EMS) providers receive minimal geriatrics-specific training while obtaining their certification. Studies have shown that they desire further training to improve their comfort level and knowledge in caring for older adults, but continuing education programs to address these needs must account for each EMS provider's specific needs, consider each provider's learning styles, and provide an engaging, interactive experience. A novel, Internet-based, video podcast-based geriatric continuing education program was developed and implemented for EMS providers, and their perceived value of the program was evaluated. They found this resource to be highly valuable and were strongly supportive of the modality and the specific training provided. Some reported technical challenges and the inability to engage in a discussion to clarify topics as barriers. It was felt that both of these barriers could be addressed through programmatic and technological revisions. This study demonstrates the proof of concept of video podcast training to address deficiencies in EMS education regarding the care of older adults, although further work is needed to demonstrate the educational effect of video podcasts on the knowledge and skills of trainees. © 2012, Copyright the Authors Journal compilation © 2012, The American Geriatrics Society.

    2018-01-01

    Full Text Available Energy-efficient data gathering techniques play a crucial role in promoting the development of smart portable devices as well as smart sensor devices based Internet of Things (IoT. For data gathering, different applications require different delay constraints; therefore, a delay Differentiated Services based Data Routing (DSDR scheme is creatively proposed to improve the delay differentiated services constraint that is missed from previous data gathering studies. The DSDR scheme has three advantages: first, DSDR greatly reduces transmission delay by establishing energy-efficient routing paths (E2RPs. Multiple E2RPs are established in different locations of the network to forward data, and the duty cycles of nodes on E2RPs are increased to 1, so the data is forwarded by E2RPs without the existence of sleeping delay, which greatly reduces transmission latency. Secondly, DSDR intelligently chooses transmission method according to data urgency: the direct-forwarding strategy is adopted for delay-sensitive data to ensure minimum end-to-end delay, while wait-forwarding method is adopted for delay-tolerant data to perform data fusion for reducing energy consumption. Finally, DSDR make full use of the residual energy and improve the effective energy utilization. The E2RPs are built in the region with adequate residual energy and they are periodically rotated to equalize the energy consumption of the network. A comprehensive performance analysis demonstrates that the DSDR scheme has obvious advantages in improving network performance compared to previous studies: it reduces transmission latency of delay-sensitive data by 44.31%, reduces transmission latency of delay-tolerant data by 25.65%, and improves network energy utilization by 30.61%, while also guaranteeing the network lifetime is not lower than previous studies.

    2012-06-01

    Full Text Available One of the pillars of the technological revolution that began in the seventies was the development of the Internet. This network has evolved in such a way that it now forms a complex structure that radically changed the social and economic dynamics at the end of century XX. Nowadays, new technologies allow anything from communication and information exchange to the realization of complex financial transactions, all from anywhere in the world and almost instantaneously. In spite of the widespread use of the Internet, there are still territories and inhabitants, mostly emplaced in remote rural areas, who live outside of this technological revolution. By contrast, urban areas enjoy a privileged position in the dissemination of the information society by concentrating most of the telecommunications infrastructure and monopolize the most qualified people. But there are many disparities in terms of diffusion of new technologies and these will transfer, in turn, to the enterprise sector which is the subject of this research. The differences in the use of new technologies and more specifically the use of advanced services on the Internet are related to the sector where the population is employed and its level of training. One of the advanced services offered by the Network is teleworking. Nowadays there are companies that offer their employees the opportunity to develop their professional activities outside their headquarters, using their homes as an alternative or call centers enabled with computers and Internet access. The purpose of this research is the study of the consumption of Internet advanced services by companies in the metropolitan area of Madrid, analyzing the spread of telework in more detail,a potential offered by new technologies and which may modify the current pattern of mobility in the main urban areas because it is from here where big companies are guiding the global economy.

  3. Constant Price of Anarchy in Network Creation Games via Public Service Advertising

    Science.gov (United States)

    Demaine, Erik D.; Zadimoghaddam, Morteza

    Network creation games have been studied in many different settings recently. These games are motivated by social networks in which selfish agents want to construct a connection graph among themselves. Each node wants to minimize its average or maximum distance to the others, without paying much to construct the network. Many generalizations have been considered, including non-uniform interests between nodes, general graphs of allowable edges, bounded budget agents, etc. In all of these settings, there is no known constant bound on the price of anarchy. In fact, in many cases, the price of anarchy can be very large, namely, a constant power of the number of agents. This means that we have no control on the behavior of network when agents act selfishly. On the other hand, the price of stability in all these models is constant, which means that there is chance that agents act selfishly and we end up with a reasonable social cost.

    infrastructure is still insufficient, the availability of high-quality internet broadband services with low rates are still difficult to realize. From the aspect of demand, stigma or the community perception that the internet is not important makes the people don't have internet access. The barriers is predominantly lack of knowledge in internet usage. This factor also causes community internet broadband literacy at level 0. As solutions, the preparation and establishment of policies and regulations such as the QoS service, interconnection, infrastructure sharing can provide high-quality internet broadband internet at a cheaper price. Besides the distribution of valuable mobile device (smartphone should also be encouraged by the application of local content level for the production of the device.

  15. VALUE-ADDED SERVICE INVESTING AND PRICING STRATEGIES FOR A TWO-SIDED PLATFORM UNDER INVESTING RESOURCE CONSTRAINT

    Guowei Dou; Ping He

    2017-01-01

    Investing on value-added service (VAS) amplifies users' participation and platform profit.However,the investing resource is usually limited in practice.This paper investigates VAS investing and pricing strategies for a two-sided platform under investing resource constraint.We reveal that with VAS investment,Subsidizing can still be done to enlarge users' demand,even when the investing cost becomes higher.For optimal pricing strategies,the network effect will be the dominating determinant if the gap between two marginal cross-side benefits (i.e.the benefit that users obtain when each new user join the other side of the platform) is large.Interestingly,we show that with the increase of the marginal investing cost,users might either be priced higher or lower.If the marginal investing cost increases to a high level,and the gap between the two marginal cross-side benefits is large,lowering the access fee for users possessing the higher cross-side network effect does not necessarily compensate more profit loss caused by higher cost.Moreover,after VAS is developed,raising the access fee for those whose marginal investing benefit is large does not necessarily generate more profit as well.The opposite strategy further enlarges users' utility,and promotes the investment to benefit more users.

    The traditional avoidance literature undeservedly neglects tax base distribution as a factor affecting the avoidance price, and generally assumed to be equal to the avoidance cost. In reality, avoidance providers are usually either high-skilled specialists or insiders. The strong collusion thus, naturally seems to be an assumption of the behavior of avoidance providers. Within such a framework, income distribution, which forms an avoidance demand together with tax codes, plays a very essentia...

    2018-02-01

    over-servicing/over-charging align well with the original intention of the NDIS, and are likely to yield the best outcomes for consumers at the lowest costs. What is known about the topic? Government-funded programs are used extensively to purchase AT because it is a primary enabler for people of all ages with disabilities. Perceptions of unreasonably high prices for AT in Australia are resulting in the widespread adoption of bulk purchasing and related strategies by governments. What does this paper add? Carefully undertaken systematic price comparisons between Australia and comparable Organization For Economic Cooperation and Development countries indicate that, on average, Australian prices are lower than elsewhere when delivery to Australia is taken into account. It was also found that prices at brick-and-mortar shops, with all the services they provide to ensure the appropriateness of the products provided to meet the consumers' needs and goals, are substantially higher than Internet purchases in which the consumer bears all the risks and responsibilities for outcomes. What are the implications? Overuse of government bulk purchasing and similar arrangements will lead to less diversity in the available AT products, related services and retail outlets, resulting in less choice for consumers and higher risks of poor outcomes through less focus on matching consumers with the 'right' products for their needs and goals, and ultimately higher AT prices over time as competition is reduced to a few major suppliers.

    2008-07-01

    A common measure to save energy in buildings is the adjustment of the operating time of the building service facilities to the busy time of the building (i.e. lowering period). For lack of better resources, the general lowering periods in irregularly occupied buildings often are reduced to a minimum or the adjustment of the operating time is completely missing. In order to adjust the operating time optimally to the actual busy time, an internet-based booking system has been developed, which allows users to register a room assignment online. This booking system is linked with the building service facilities. This ensure the optimal setting of the lowering periods and therefore allows saving energy. The technical implementation resulted from a programmable logic controller (PLC) that can be accessed via a web browser. Temperature offset boxes have been added as interface between the PLC and the existing facilities in order that the system is applicable in existing buildings too. The booking system has been installed in two test objects and has also been successfully tested with the responsible staff (caretaker, real estate management). The booking system may be contemplated online: http://www.hetag.ch. (author)

    This paper describes our conceptual framework of closed-loop lifecycle information sharing for product-service in the Internet of Things (IoT). The framework is based on the ontology model of product-service and a type of IoT message standard, Open Messaging Interface (O-MI) and Open Data Format (O-DF), which ensures data communication. (1) BACKGROUND: Based on an existing product lifecycle management (PLM) methodology, we enhanced the ontology model for the purpose of integrating efficiently the product-service ontology model that was newly developed; (2) METHODS: The IoT message transfer layer is vertically integrated into a semantic knowledge framework inside which a Semantic Info-Node Agent (SINA) uses the message format as a common protocol of product-service lifecycle data transfer; (3) RESULTS: The product-service ontology model facilitates information retrieval and knowledge extraction during the product lifecycle, while making more information available for the sake of service business creation. The vertical integration of IoT message transfer, encompassing all semantic layers, helps achieve a more flexible and modular approach to knowledge sharing in an IoT environment; (4) Contribution: A semantic data annotation applied to IoT can contribute to enhancing collected data types, which entails a richer knowledge extraction. The ontology-based PLM model enables as well the horizontal integration of heterogeneous PLM data while breaking traditional vertical information silos; (5) CONCLUSION: The framework was applied to a fictive case study with an electric car service for the purpose of demonstration. For the purpose of demonstrating the feasibility of the approach, the semantic model is implemented in Sesame APIs, which play the role of an Internet-connected Resource Description Framework (RDF) database.

  8. Going beyond best technology and lowest price: on renewable energy investors’ preference for service-driven business models

    International Nuclear Information System (INIS)

    Loock, Moritz

    2012-01-01

    Renewable energy is becoming increasingly important for economies in many countries. But still in an emerging industry, renewable energy requires supportive energy policy helping firms to develop and protect competitive advantages in global competition. As a guideline for designing such policy, we consult well-informed stakeholders within the renewable energy industry: investors. Their preferences serve as explorative indicator for assessing which business models might succeed in competition. To contribute to only limited research on renewable energy investors’ preferences, we ask, which business models investment managers for renewable energy prefer to invest in. We report from an explorative study of 380 choices of renewable energy investment managers. Based on the stated preferences, we modelled three generic business models to calculate the share of investors’ preferences. We find exiting evidence: a “customer intimacy” business model that proposes best services is much more preferred by investors than business models that propose lowest price or best technology. Policy-makers can use those insights for designing policy that supports service-driven business models for renewable energy with a scope on customer needs rather than technology or price. Additionally, we state important implications for renewable energy entrepreneurs, managers and research.

  9. Marketplace pricing

    International Nuclear Information System (INIS)

    Anon.

    1991-01-01

    As discussed in this chapter, interest in marketplace pricing has been increasing in recent years, reflecting the societal trend toward substituting competition for regulation where appropriate. Competition is valuable because it encourages utilities to make efficient decisions with a minimum of regulatory intervention. It enhances efficiency through the incentive for innovation by the regulated companies and by increasing the likelihood they will come forward with proposals for better services, lower prices or both. Ultimately, consumers are beneficiaries. Marketplace pricing is emblematic of the view that the degree of regulation should reflect the degree of market power, that workably competitive markets should be allowed to operate with as little regulatory interference as possible. The Edison Electric Institute has made perhaps the most detailed proposal on marketplace pricing. It and others perceive numerous benefits from this method of pricing transmission services. Given the undeniable market power resulting from line ownership, FERC has emphasized the need to find a workably competitive market before approving such proposals. The ability to make this distinction without a full-blown antitrust review for every transaction is questionable, and FERC has yet to provide generic guidance. Finally, FERC's legal ability to depart from cost-based standards is questionable

  10. The Impact of Food Quality Information Services on Food Supply Chain Pricing Decisions and Coordination Mechanisms Based on the O2O E-Commerce Mode

    Xiaoqiu Yu

    2018-01-01

    Full Text Available This paper considers the price conflict problem between the online channel of a food processing factory and the offline channel of the food retailers in food supply chains by analyzing the pricing decisions and coordination mechanisms between the food processing factory and food retailers under the influence of a food quality information service. First, the Stackelberg game method and the Bertrand game method are used to optimize the pricing decisions with the goal of maximizing the profits of the food processing factory and retailer. The analysis shows that the food quality information service level is positively correlated with the price of the factory’s own channel, and the influence of the food quality information service level on the price of the food processing factory’s or the food retailer’s own channel is stronger than its influence on the price of a competitor’s channel. Second, the food supply chain members’ pricing decisions are analyzed using the case analysis method by considering practical problems in the food supply chain. The results indicate that the food processing factory should use the Stackelberg game to make pricing decisions. However, it is optimal for the food retailer to make pricing decisions under the Bertrand game, and the total profit of the food supply chain is optimized under centralized decision making. Finally, we use both the quantitative discount mechanism and the Stackelberg game method to analyze the profits obtained by the food processing factory and retailer. The results indicate that the food processing factory should implement a quantitative discount mechanism when the quantity discount coefficient is greater than 0.4, and the retailer should implement a quantity discount mechanism when the quantity discount coefficient is in the range of 0.25 to 0.4.

    Full Text Available The world is facing a global financial and economic crisis, the deepest and the widest spread since the Great Depression of 1930. Individuals, companies and governments alike are forced to take active measures to counteract the severe consequences of the crisis, if they want to emerge stronger from this difficult period. There are strong beliefs among policy makers around the world, European Union included, that the Information and Communication Technologies are a very important pillar in the recovery from the crisis. This paper aims at evaluating the e-banking services, internet enabled conferencing solutions and electronic public services as categories of ICT enabled services that represent powerful and practical solutions, especially in time of crisis, with significant advantages at individual, company and government level.

  4. Auction-Based Cloud Service Pricing and Penalty with Availability on Demand

    Full Text Available Availability is one of the main concerns of cloud users, and cloud providers always try to provide higher availability to improve user satisfaction. However, higher availability results in higher provider costs and lower social welfare. In this paper, taking into account both the users’ valuation and desired availability, we design resource allocation, pricing and penalty mechanisms with availability on demand. Considering two scenarios: public availability in which the desired availabilities of all users are public information, and private availability in which the desired availabilities are private information of users, and, analyzing the possible behaviours of users, we design a truthful deterministic mechanism with 2-approximation in public availability scenario and a universal truthful mechanism with 1 1 + γ approximation in private availability scenario, where γ is the backup ratio of resources with the highest availability. The experiment results show that our mechanisms significantly improve the social welfare compared to the mechanism without considering availability demand of users.

    Full Text Available Latin American (LA megacities are facing enormous challenges to provide welfare to millions of people who live in them. High rates of urbanization and limited administrative capacity of LA cities to plan and control urban growth have led to a critical deficit of urban green space, and therefore, to sub-optimal outcomes in terms of urban sustainability. This study seeks to assess the possibility of using real estate prices to provide an estimate of the monetary value of the ecosystem services provided by urban green space across five Latin American megacities: Bogota, Buenos Aires, Lima, Mexico City and Santiago de Chile. Using Google Earth images to quantify urban green space and multiple regression analysis, we evaluated the impact of urban green space, crime rates, business density and population density on real estate prices across the five mentioned megacities. In addition, for a subset of the data (Lima and Buenos Aires we analyzed the effects of landscape ecology variables (green space patch size, connectivity, etc. on real estate prices to provide a first insight into how the ecological attributes of urban green space can determine the level of ecosystem service provision in different urban contexts in Latin America. The results show a strong positive relationship between the presence of urban green space and real estate prices. Green space explains 52% of the variability in real estate prices across the five studied megacities. Population density, business density and crime had only minor impacts on real estate prices. Our analysis of the landscape ecology variables in Lima and Buenos Aires also show that the relationship between green space and price is context-specific, which indicates that further research is needed to better understand when and where ecological attributes of green space affect real estate prices so that managers of urban green space in LA cities can optimize ecological configuration to maximize ecosystem service

    Ensuring rapid access to high quality sexual health services is a key public health objective, both in the United Kingdom and internationally. Internet-based testing services for sexually transmitted infections (STIs) are considered to be a promising way to achieve this goal. This study will evaluate a nascent online STI testing and results service in South East London, delivered alongside standard face-to-face STI testing services. The aim of this study is to establish whether an online testing and results services can (1) increase diagnoses of STIs and (2) increase uptake of STI testing, when delivered alongside standard face-to-face STI testing services. This is a single-blind randomized controlled trial. We will recruit 3000 participants who meet the following eligibility criteria: 16-30 years of age, resident in the London boroughs of Lambeth and Southwark, having at least one sexual partner in the last 12 months, having access to the Internet and willing to take an STI test. People unable to provide informed consent and unable to read and understand English (the websites will be in English) will be excluded. Baseline data will be collected at enrolment. This includes participant contact details, demographic data (date of birth, gender, ethnicity, and sexual orientation), and sexual health behaviors (last STI test, service used at last STI test and number of sexual partners in the last 12 months). Once enrolled, participants will be randomly allocated either (1) to an online STI testing and results service (Sexual Health 24) offering postal self-administered STI kits for chlamydia, gonorrhoea, syphilis, and HIV; results via text message (short message service, SMS), except positive results for HIV, which will be delivered by phone; and direct referrals to local clinics for treatment or (2) to a conventional sexual health information website with signposting to local clinic-based sexual health services. Participants will be free to use any other interventions

    The transition to a largely Internet and Web-based environment for dissemination of health information has changed the health information landscape and the framework for evaluation of such activities. A multidimensional evaluative approach is needed. This paper discusses one important dimension of Web evaluation-usage data. In particular, we discuss the collection and analysis of external data on website usage in order to develop a better understanding of the health information (and related US government information) market space, and to estimate the market share or relative levels of usage for National Library of Medicine (NLM) and National Institutes of Health (NIH) websites compared to other health information providers. The primary method presented is Internet audience measurement based on Web usage by external panels of users and assembled by private vendors-in this case, comScore. A secondary method discussed is Web usage based on Web log software data. The principle metrics for both methods are unique visitors and total pages downloaded per month. NLM websites (primarily MedlinePlus and PubMed) account for 55% to 80% of total NIH website usage depending on the metric used. In turn, NIH.gov top-level domain usage (inclusive of NLM) ranks second only behind WebMD in the US domestic home health information market and ranks first on a global basis. NIH.gov consistently ranks among the top three or four US government top-level domains based on global Web usage. On a site-specific basis, the top health information websites in terms of global usage appear to be WebMD, MSN Health, PubMed, Yahoo! Health, AOL Health, and MedlinePlus. Based on MedlinePlus Web log data and external Internet audience measurement data, the three most heavily used cancer-centric websites appear to be www.cancer.gov (National Cancer Institute), www.cancer.org (American Cancer Society), and www.breastcancer.org (non-profit organization). Internet audience measurement has proven useful to NLM

    Cloud computing is the new enabling technology that offers centralised computing, flexible data storage and scalable services. In the manufacturing context, it is possible to utilise the Cloud technology to integrate and provide industrial resources and capabilities in terms of Cloud services. In this paper, a function block-based integration mechanism is developed to connect various types of production resources. A Cloud-based architecture is also deployed to offer a service pool which maintains these resources as production services. The proposed system provides a flexible and integrated information environment for the Cloud-based production system. As a specific type of manufacturing, Waste Electrical and Electronic Equipment (WEEE) remanufacturing experiences difficulties in system integration, information exchange and resource management. In this research, WEEE is selected as the example of Internet of Things to demonstrate how the obstacles and bottlenecks are overcome with the help of Cloud-based informatics approach. In the case studies, the WEEE recycle/recovery capabilities are also integrated and deployed as flexible Cloud services. Supporting mechanisms and technologies are presented and evaluated towards the end of the paper.

    Cost-reducing programmes are only the first step in a series of measures to be taken by the power utilities in order to become fit for the free competition markets. A great number of empirical studies on the future power markets do show that for the customers, prices are a priority criterium, but offering competitive prices alone will not suffice to keep one`s competitive edge. The negative consequences of pure price competition (shown by the aviation industry) and the lessons to be learned from ``intelligent`` branches of industry, (eg. mineral oil and cigarettes), who have been clever enough to avoid price cutting wars, demonstrate that there are chances for development also in deregulated power markets. (orig./CB) [Deutsch] Zur Vorbereitung auf die anstehende Liberalisierung muss eine Neuausrichtung der EVU schnellstmoeglich erfolgen. Reine Kostensenkungsprogramme sind dabei nur der erste Schritt, um fuer den Wettbewerb fit zu werden. Hierzu zaehlt die strategische und marketingorientierte Ausrichtung des Unternehmens auf den Wettbewerb. Zahlreiche empirische Studien zum EVU-Markt kommen zwar zu dem Ergebnis, dass aus der Sicht des Kunden der Preis einen hohen Stellenwert einnimmt. Ein wettbewerbsorientierter Preis ist notwendig, reicht aber zum erfolgreichen Ueberleben im Wettbewerb alleine nur bei ueberlegener Kostenfuehrerschaft aus. Die negativen Auswirkungen eines reinen Preiswettbewerbs (Luftfahrt) sowie die Lehren aus `intelligenten` Branchen (Mineraloel-, Zigarettenindustrie), die dies vermeiden, zeigen die vielfaeltigen Entwicklungsmoeglichkeiten auch fuer den Energie-Wettbewerbsmarkt auf.

Knowing what influences WTP is an important matter because validity of CVM in medical services remains controversial. The objective of this survey is to measure WTP for the treatment of typical acute illnesses and to analyze the factors affecting WTP. Methods A questionnaire survey was conducted over the Internet, in which 795 men and women between 40 and 59 years old responded to questions about WTP for medical expenses in three hypothetical scenarios: common cold (CC, retinal detachment (RD and myocardiac infarction (MI. Results Mean WTP was $29.9 for CC, $2,233 for RD, and $8,976 for MI. WTP for RD and MI was lower in the low-income group. While WTP for CC did not vary with income, WTP was higher in groups whose current subjective fitness levels were low. Conclusion Although WTP measurements are criticized frequently for their validity and reliability, they are still useful for determining the economic value of medical services. Based on the results of this study, it is deemed necessary to enhance safety nets for low-income earners in regards to serious illnesses that incur high medical expenses. Further, it is recommended that the rate of co-payments be set relatively high with respect to mild illnesses for which alternative services are available.

This article presents a discourse analysis of 101 responses to 98 questions that were posted on 14 different Internet-based mental health services in Norway and Sweden. We aimed to examine and describe the dominant understandings and favored recommendations in the services’ answers, and we reflected upon the social consequences of those answers. The services generally understood life struggles as an abnormal state of mind, life rhythms, or self-reinforcing loops. Internet-based mental health services primarily counsel service users to seek help, talk to health care professionals face-to-face, and discuss their life struggles openly and honestly. They also urge service users to take better care of themselves and socialize with other people. However, such answers might enhance the individualization of life problems, masking social origin and construction. Consequently, the services are challenged to include social explanations in their answers and strengthen their responsibility to amplify peoples’ messages at a societal level. Potentially, such answers could strengthen democratic structures and put pressure on social equity.Keywords: depression, e-mental health, health psychology, Internet, public health

  11. Internet Sexualities

    Science.gov (United States)

    Döring, Nicola

    The term “internet sexuality” (or OSA, online sexual activities) refers to sexual-related content and activities observable on the internet (cf. Adams, Oye, & Parker, 2003; Cooper, McLoughlin, & Campbell, 2000; Leiblum & Döring, 2002). It designates a variety of sexual phenomena (e.g., pornography, sex education, sexual contacts) related to a wide spectrum of online services and applications (e.g., websites, online chat rooms, peer-to-peer networks). If an even broader range of computer networks - such as the Usenet or bulletin board systems - is included in this extensional definition, one speaks of “online sexuality” or “cybersexuality.”

    Full Text Available Internet-accessed sexually transmitted infection testing (e-STI testing is increasingly available as an alternative to testing in clinics. Typically this testing modality enables users to order a test kit from a virtual service (via a website or app, collect their own samples, return test samples to a laboratory, and be notified of their results by short message service (SMS or telephone. e-STI testing is assumed to increase access to testing in comparison with face-to-face services, but the evidence is unclear. We conducted a randomised controlled trial to assess the effectiveness of an e-STI testing and results service (chlamydia, gonorrhoea, HIV, and syphilis on STI testing uptake and STI cases diagnosed.The study took place in the London boroughs of Lambeth and Southwark. Between 24 November 2014 and 31 August 2015, we recruited 2,072 participants, aged 16-30 years, who were resident in these boroughs, had at least 1 sexual partner in the last 12 months, stated willingness to take an STI test, and had access to the internet. Those unable to provide consent and unable to read English were excluded. Participants were randomly allocated to receive 1 text message with the web link of an e-STI testing and results service (intervention group or to receive 1 text message with the web link of a bespoke website listing the locations, contact details, and websites of 7 local sexual health clinics (control group. Participants were free to use any other services or interventions during the study period. The primary outcomes were self-reported STI testing at 6 weeks, verified by patient record checks, and self-reported STI diagnosis at 6 weeks, verified by patient record checks. Secondary outcomes were the proportion of participants prescribed treatment for an STI, time from randomisation to completion of an STI test, and time from randomisation to treatment of an STI. Participants were sent a £10 cash incentive on submission of self-reported data. We

    A global economic analysis methodology is proposed in order to simplify the cost and the profitability assessment of energy and services delivered by photovoltaic (PV) systems. As examples, equations and graphic tools derived from this methodology give directly the overall discounted costs (ODC) of electricity delivered by grid-connected PV power plants and the ODC of water delivered by a stand-alone PV pumping system. The main criteria used for profitability analysis of PV projects are reviewed: net present value, internal rate of return and profitability index (PI). A simple method with associated equations and graphic tools is presented in order to assess the profitability of PV projects from their PI. Examples of profitability analysis of present and future grid-connected PV power plants built and operated by an independent power producers are presented and discussed, together with examples of stand-alone PV water pumping systems operated by the local community in developing countries. In both cases, equations and specific graphic tools are presented. Specific graphs can be used with different monetary units, different sizes and different investment costs of PV projects. (Author)

  17. Pricing of Vehicle-to-Grid Services in a Microgrid by Nash Bargaining Theory

    2017-01-01

    Full Text Available Owners of electric vehicles (EVs can offer the storage capacity of their batteries to the operator of a microgrid as a service called vehicle-to-grid (V2G to hold the balance between supply and demand of electricity, particularly when the microgrid has intermittent renewable energy sources. Literature review implies that V2G has economic benefits for both microgrid operator and EV owners, but it is unclear how these benefits are divided between them. The challenge grows when the policy makers rely on the V2G revenue as an incentive for expanding the penetration of EVs in the automotive market. This paper models the interaction between microgrid operator and EV owners as a bargaining game to determine how the benefits of V2G should be divided. The method has been implemented on a hybrid power system with high wind penetration in addition to diesel generators in Manjil, Iran. The results indicate that, in addition to V2G benefits, government subsidies are necessary to promote the use of EVs.

    With the increased interest in competitive market forces and growing recognition of the deficiencies in current practices, FERC and others are exploring alternatives to embedded cost pricing. A number of these alternatives are discussed in this chapter. Marketplace pricing, discussed briefly here, is the subject of the next chapter. Obviously, the pricing formula may combine several of these methodologies. One utility of which the authors are aware is seeking a price equal to the sum of embedded costs, opportunity costs, line losses, value of service, FERC's percentage adder formula and a contract service charge

    Despite the growing evidence of the benefits of physical activity (PA) in individuals with rheumatoid arthritis (RA), the majority is not physically active enough. An innovative strategy is to engage lead users in the development of PA interventions provided over the internet. The aim was to explore lead users' ideas and prioritization of core features in a future internet service targeting adoption and maintenance of healthy PA in people with RA. Six focus group interviews were performed with a purposively selected sample of 26 individuals with RA. Data were analyzed with qualitative content analysis and quantification of participants' prioritization of most important content. Six categories were identified as core features for a future internet service: up-to-date and evidence-based information and instructions, self-regulation tools, social interaction, personalized set-up, attractive design and content, and access to the internet service. The categories represented four themes, or core aspects, important to consider in the design of the future service: (1) content, (2) customized options, (3) user interface and (4) access and implementation. This is, to the best of our knowledge, the first study involving people with RA in the development of an internet service to support the adoption and maintenance of PA.Participants helped identifying core features and aspects important to consider and further explore during the next phase of development. We hypothesize that involvement of lead users will make transfer from theory to service more adequate and user-friendly and therefore will be an effective mean to facilitate PA behavior change.

    Full Text Available Accounting of telecommunication services is closely related to the functions of authentication and authorization. These functions are usually considered together and implemented within the same server using a common protocol. The most renowned protocols for authentication, authorization and accounting are the RADIUS and Diameter protocols.   AAA functions and related protocols   In this chapter, the accounting management architecture developed by IETF is presented. It includes the interaction between network elements, accounting servers and billing and charging servers. Accounting data can be used for management, planning and charging users as well as other (specific purposes. Authentication is the process of confirming a user's digital identity, usually through some type of identifiers and related data. Authorization determines whether a particular entity is authorized to perform an activity.   Basic Functions of the RADIUS Protocol   The RADIUS architecture is based on a client-server model. It uses UDP on the transport layer. Transactions between the client and the server are authenticated, which is achieved by using a common secret key that is never sent through the network. Given the limited resources available to network devices, RADIUS facilitates and centralizes charging end users, provides some protection against active attacks by unauthorized users and it has great support from different network equipment vendors. Although RADIUS is a widely accepted protocol for the mechanisms of authentication, authorization and accounting, it has certain shortcomings that may be caused by the protocol itself or by its poor implementation.   Architecture and Operation of the Diameter Protocol   Diameter is a scalable protocol designed by the IETF working group in order to eliminate shortcomings and functional limitations of the RADIUS protocol and eventually to replace it in the near future. Most of the basic Diameter mechanisms and its

    Full Text Available Recently, with multimedia services such as IPTV, video conferencing has emerged as a main traffic source. When UDP coexists with TCP, it induces not only congestion collapse but also an unfairness problem. In this paper, a new Active Queue Management algorithm, called Traffic Sensitive Active Queue Management (TSAQM, is proposed for providing multimedia services in routers. The TSAQM is comprised of Dynamic Weight Allocate Scheme (DWAS and Service Guarantee Scheme (SGS. The purpose of DWAS is to fairly allocate resources with high end-user utility, and the SGS is to determine the satisfactory threshold (TH and threshold region (TR. Besides, a multiqueue design for different priority traffic, and threshold TH and threshold region TR is proposed to achieve the different QoS requirements. Several objectives of this proposed scheme include achieving high end user utility for video services, considering the multicast as well as unicast proprieties to meet interclass fairness, and achieving the QoS requirement by adaptively adjusting the thresholds based on the traffic situations. Performance comparisons with the GRED-I are in terms of packet dropping rate and throughput to highlight the better behavior of the proposed schemes due to taking into account the fairness and different weights for video layers.

    Although increasing numbers of young people are seeking help online for self-injury, relatively little is known about their online help-seeking preferences. To investigate the perspectives of young people who self-injure regarding online services, with the aim of informing online service delivery. A mixed-methods exploratory analysis regarding the perspectives of a subsample of young people who reported a history of self-injury and responded to questions regarding preferences for future online help-seeking (N = 457). The sample was identified as part of a larger study (N = 1,463) exploring self-injury and help-seeking. Seven themes emerged in relation to preferences for future online help-seeking: information, guidance, reduced isolation, online culture, facilitation of help-seeking, access, and privacy. Direct contact with a professional via instant messaging was the most highly endorsed form of online support. Young people expressed clear preferences regarding online services for self-injury, supporting the importance of consumer consultation in development of online services.

    Current generation wireless sensor routing algorithms and protocols have been designed based on a myopic routing approach, where the motes are assumed to have the same sensing and communication capabilities. Myopic routing is not a natural fit for the IoT, as it may lead to energy imbalance and subsequent short-lived sensor networks, routing the sensor readings over the most service-intensive sensor nodes, while leaving the least active nodes idle. This paper revisits the issue of energy efficiency in sensor networks to propose a clustering model where sensor devices' service delivery is mapped into an energy awareness model, used to design a clustering algorithm that finds service-aware clustering (SAC) configurations in IoT settings. The performance evaluation reveals the relative energy efficiency of the proposed SAC algorithm compared to related routing algorithms in terms of energy consumption, the sensor nodes' life span and its traffic engineering efficiency in terms of throughput and delay. These include the well-known low energy adaptive clustering hierarchy (LEACH) and LEACH-centralized (LEACH-C) algorithms, as well as the most recent algorithms, such as DECSA and MOCRN.

    Data communication service has an important influence on e-commerce. The key challenge for the users is, ultimately, to select a suitable provider. However, in this article, we do not focus on this aspect but the viewpoint and decision-making of providers for order allocation and pricing policy when orders exceed service capacity. It is a multiple criteria decision-making problem such as profit and cancellation ratio. Meanwhile, we know realistic situations in which much of the input information is uncertain. Thus, it becomes very complex in a real-life environment. In this situation, fuzzy sets theory is the best tool for solving this problem. Our fuzzy model is formulated in such a way as to simultaneously consider the imprecision of information, price sensitive demand, stochastic variables, cancellation fee and the general membership function. For solving the problem, a new fuzzy programming is developed. Finally, a numerical example is presented to illustrate the proposed method. The results show that it is effective for determining the suitable order set and pricing policy of provider in data communication service with different quality of service (QoS) levels.

  11. Not All Large Customers are Made Alike: Disaggregating Response to Default-Service Day-Ahead Market Pricing

    International Nuclear Information System (INIS)

    Hopper, Nicole; Goldman, Charles; Neenan, Bernie

    2006-01-01

    For decades, policymakers and program designers have gone on the assumption that large customers, particularly industrial facilities, are the best candidates for realtime pricing (RTP). This assumption is based partly on practical considerations (large customers can provide potentially large load reductions) but also on the premise that businesses focused on production cost minimization are most likely to participate and respond to opportunities for bill savings. Yet few studies have examined the actual price response of large industrial and commercial customers in a disaggregated fashion, nor have factors such as the impacts of demand response (DR) enabling technologies, simultaneous emergency DR program participation and price response barriers been fully elucidated. This second-phase case study of Niagara Mohawk Power Corporation (NMPC)'s large customer RTP tariff addresses these information needs. The results demonstrate the extreme diversity of large customers' response to hourly varying prices. While two-thirds exhibit some price response, about 20 percent of customers provide 75-80 percent of the aggregate load reductions. Manufacturing customers are most price-responsive as a group, followed by government/education customers, while other sectors are largely unresponsive. However, individual customer response varies widely. Currently, enabling technologies do not appear to enhance hourly price response; customers report using them for other purposes. The New York Independent System Operator (NYISO)'s emergency DR programs enhance price response, in part by signaling to customers that day-ahead prices are high. In sum, large customers do currently provide moderate price response, but there is significant room for improvement through targeted programs that help customers develop and implement automated load-response strategies

    Objective: To introduce the development strategy of " Internet Plus" AIDS prevention services and its implementation results from 2010 to 2015 in Guangzhou, China. Methods: A gay men's health column was created for an active website aimed at men who have sex with men(MSM), in collaboration with local community organizations and the Guangzhou CDC. We designed intervention tools(including scenario-based applications and HIV risk self-assessment systems)and an online HIV testing service platform, integrated with applied psychology and behavioral theory as well as the " Internet Plus" concept, to intervene in HIV infection risk factors among MSM. Data of clients who accessed the " Internet Plus" AIDS services from 2010 to 2015 were used to evaluate service operation. Six-year consecutive surveys, conducted between April and July of each service year, were collected using a national AIDS sentinel surveillance questionnaire. For each year of surveillance, information on HIV prevalence, HIV interventions received during the past year, unprotected anal intercourse in the past 6 months, and HIV testing in the past year were compared using the chi-squared(χ 2 )test, to roughly reflect the effect of"Internet Plus" AIDS prevention services. Results: As of 31 December 2015, a total of 34 395 MSM had received " Internet Plus" services and HIV testing. The number of MSM tested increased from 2 338 in 2010 to 8 054 in 2015. From 2010 to 2015, newly identified HIV cases in each year were 59, 166, 312, 283, 291, and 270, which accounted for 25.0%, 32.8%, 38.8%, 35.1%, 30.5%, and 23.2% of MSM HIV cases of Guangzhou, respectively. Sentinel surveillance data showed that during the study period, 3 047 MSM were investigated, with 405, 400, 401, 633, 608, and 600 each year, respectively. The proportion of participants who had received any HIV intervention during the past year was 74.3%(301), 70.8%(283), 83.3%(334), 85.0%(538), 69.1%(420), and 83.8%(503)each year, respectively(trend χ 2

    Over the past decade, the increasing availability of the World Wide Web has held out the possibility that the efficiency of scientific measurements could be enhanced in cases where experiments were being conducted at distant facilities. Examples of early successes have included X-ray diffraction (XRD) experimental measurements of protein crystal structures at synchrotrons and access to scanning electron microscopy (SEM) and NMR facilities by users from institutions that do not possess such advanced capabilities. Experimental control, visual contact, and receipt of results has used some form of X forwarding and/or VNC (virtual network computing) software that transfers the screen image of a server at the experimental site to that of the users' home site. A more recent development is a web services platform called Science Studio that provides teams of scientists with secure links to experiments at one or more advanced research facilities. The software provides a widely distributed team with a set of controls and screens to operate, observe, and record essential parts of the experiment. As well, Science Studio provides high speed network access to computing resources to process the large data sets that are often involved in complex experiments. The simple web browser and the rapid transfer of experimental data to a processing site allow efficient use of the facility and assist decision making during the acquisition of the experimental results. The software provides users with a comprehensive overview and record of all parts of the experimental process. A prototype network is described involving X-ray beamlines at two different synchrotrons and an SEM facility. An online parallel processing facility has been developed that analyzes the data in near-real time using stream processing. Science Studio and can be expanded to include many other analytical applications, providing teams of users with rapid access to processed results along with the means for detailed

    In 1977 NASA published Shuttle Reimbursement Policies for Civil U.S. Government, DOD and Commercial and Foreign Users. These policies were based on the principle of total cost recovery over a period of time with a fixed flat price for initial period to time to enhance transition. This fixed period was to be followed with annual adjustments thereafter, NASA is establishing a new price for 1986 and beyond. In order to recover costs, that price must be higher than the initial fixed price through FY 1985. NASA intends to remain competitive. Competitive posture includes not only price, but other factors such as assured launch, reliability, and unique services. NASA's pricing policy considers all these factors.

    The Internet and emergent telecommunications infrastructures are transforming the future of health care management. The costs of health care delivery systems, products, and services continue to rise everywhere, but performance of health care delivery is associated with institutional and ideological considerations as well as availability of financial and technological resources. to identify the effects of ideological differences on health care market infrastructures including the Internet and telecommunications technologies by a comparative case analysis of two large health care organizations: the British National Health Service and the California-based Kaiser Permanente health maintenance organization. A qualitative comparative analysis focusing on the British National Health Service and the Kaiser Permanente health maintenance organization to show how system infrastructures vary according to market dynamics dominated by health care institutions ("push") or by consumer demand ("pull"). System control mechanisms may be technologically embedded, institutional, or behavioral. The analysis suggests that telecommunications technologies and the Internet may contribute significantly to health care system performance in a context of ideological diversity. The study offers evidence to validate alternative models of health care governance: the national constitution model, and the enterprise business contract model. This evidence also suggests important questions for health care policy makers as well as researchers in telecommunications, organizational theory, and health care management.

    Abstract Background Korean Neuropsychiatric Association changed the Korean term for schizophrenia from ‘split-mind disorder’ to ‘attunement disorder’ in 2012, to dispel the stigma associated with name, and to promote early detection and treatment. Information on the internet affects the public awareness and attitude toward schizophrenia. The main purpose of this study was to investigate the correlation between renaming schizophrenia and the pattern of mental health services utilization by big data analysis of internet (newspaper articles and internet searches) in Korea. Methods From January 2016 to September 2017, newspaper articles on “attunement disorder” and “split-mind disorder” available on the internet were classified as related with negative images like crime and helpful or positive in dispelling the stigma. The relationship between the number of anti-stigma newspaper articles and newspaper articles of schizophrenia containing both positive and negative images was examined. In addition, using Naver, a major internet search engine in Korea, we investigated the total number of internet searches of both old and new name of schizophrenia by gender differences. Finally, the frequency of the visits of mental health services of patients with schizophrenia was measured using the Korean Healthcare Bigdata Hub (http://opendata.hira.or.kr/home.do#none) for 14 months and the correlation between the frequency of the visits and the above big data was examined. The data were analyzed using the SPSS/WIN 24.0. Pearson correlation coefficients were used to analyze correlations. Results The amounts of newspaper articles containing anti-stigma of schizophrenia were correlated with the amounts of newspaper articles containing negative images like crime of the new name (attunement disorder) of schizophrenia (r=0.528, p0.05) in next month was larger than the correlation of “split-mind disorder” searches with mental health services utilization (r = 0.082, p>0

    It is believed that laboratory tariffs in Iran don't reflect the real costs. This might expose private laboratories at financial hardship. Activity Based Costing is widely used as a cost measurement instrument to more closely approximate the true cost of operations. This study aimed to determine the real price of different clinical tests of a selected private clinical laboratory. This study was a cross sectional study carried out in 2015. The study setting was the private laboratories in the city of Kerman, Iran. Of 629 tests in the tariff book of the laboratory (relative value), 188 tests were conducted in the laboratory that used Activity Based Costing (ABC) methodology to estimate cost-price. Analyzing and cost-price estimating of laboratory services were performed by MY ABCM software Version 5.0. In 2015, the total costs were $641,645. Direct and indirect costs were 78.3% and 21.7% respectively. Laboratory consumable costs by 37% and personnel costs by 36.3% had the largest share of the costing. Also, group of hormone tests cost the most $147,741 (23.03%), and other tests group cost the least $3,611 (0.56%). Also after calculating the cost of laboratory services, a comparison was made between the calculated price and the private sector's tariffs in 2015. This study showed that there was a difference between costs and tariffs in the private laboratory. One way to overcome this problem is to increase the number of laboratory tests with regard to capacity of the laboratories.

    2012-03-01

    The relationship between health information seeking, patient engagement and health literacy is not well understood. This is especially true in medically underserved populations, which are often viewed as having limited access to health information. To improve communication between an urban health centre and the community it serves, a team of library and information science researchers undertook an assessment of patients' level and methods of access to and use of the Internet. Data were collected in 53 face-to-face anonymous interviews with patients at the centre. Interviews were tape-recorded for referential accuracy, and data were analysed to identify patterns of access and use. Seventy-two percentage of study participants reported having access to the Internet through either computers or cell phones. Barriers to Internet access were predominantly lack of equipment or training rather than lack of interest. Only 21% of those with Internet access reported using the Internet to look for health information. The findings suggest that lack of access to the Internet in itself is not the primary barrier to seeking health information in this population and that the digital divide exists not at the level of information access but rather at the level of information use. © 2011 The authors.

  19. Price Strategies in Banking Marketing

    Directory of Open Access Journals (Sweden)

    Iuliana Cetina

    2007-01-01

    Full Text Available All organizations must settle a price for the services they offer. The price for services is an important element of the marketing mix, being an important income source for the organization. The settlement of a correct price, both for the market and the competition, is a significant element for the sector of financial - banking services. Another important factor to take into consideration is the fact that the banks do not settle only the prices for individual services, but also coordinate their prices for service packages. As the competition in the financial - banking services has intensified, the settlement of correct prices has become an essential element for the marketing strategy. Nevertheless it is important to remind that the price is not a central element. There are other significant grounds, the price being only one of the elements of the marketing mix. Although in Romania many customers may be sensitive in present to the price, as the competition will increase, the quality of the services will become more important to the customers, and the demand will be complex.

    While the distinct behaviors of for-profit and non-profit providers in the healthcare market have been compared in the economic literature, their choices regarding market entry and exit have only recently been debated. Since 2000, when public Long-Term Care Insurance was introduced in Japan, for-profit providers have been able to provide formal long-term homecare services. The aim of this study is to determine which factors have affected market entry of for-profit providers under price regulation and in competition with existing non-profit providers. We used nation-wide panel data from 2002 to 2010, aggregated at the level of local public insurers (n = 1557), a basic area unit of service provision. The number of for-profit providers per elderly population in the area unit was regressed against factors related to local demand and service costs using first-difference linear regression, a fixed effects model, and Tobit regression for robustness checking. Results showed that demand (the number of eligible care recipients) and cost factors (population density and minimum wage) significantly influenced for-profit providers' choice of market entry. These findings indicate that for-profit providers will strategically choose a local market for maximizing profit. We believe that price regulation should be redesigned to incorporate quality of care and market conditions, regardless of the profit status of the providers, to ensure equal access to efficient delivery of long-term care across all regions.

    The present study developed and tested a model that explains how people who believe that others have unrealistically high standards and exert pressure on them to be perfect (that is, people high in socially prescribed perfectionism) develop a problematic use of internet communicative services (GPIU). Following the perfectionism social disconnection model and previous evidence about the role that the online environment might play in the development of problematic internet use, low reported social support and the fear of negative evaluations in face to face interactions were hypothesized to mediate the association between socially prescribed perfectionism and GPIU. A sample of 465 undergraduate students was recruited (240 F; mean age 21.91+2.23years), and the hypotheses were tested through structural equation modeling separately for men and women. Among men, the association between SPP and GPIU was fully mediated by the fear of being negatively evaluated and the perception of low social support. For women, we found a partially mediated model in which SPP affected GPIU indirectly through the fear of negative evaluations. The presence of a direct effect of SPP on GPIU was also found. Moreover, perceived social support was not found to be a significant mediator among women. The findings suggest that problematic use of internet communicative services might be, at least in part, a defensive response to extreme social evaluation pressures. Copyright © 2014 Elsevier Ltd.

    Webb, M. G.

    1977-10-15

    Some economic principles of energy pricing in a market type economy in which there is consumer sovereignty are discussed. Thus resources will be allocated via the production processes in line with the preferences of consumers as revealed by their purchases of goods and services. Prices play the crucial role of coordinating instruments in this allocative process. It is assumed that all the energy industries are in the public sector. The following topics are discussed: the specification of objectives for the energy sector; marginal cost pricing; problems associated with the measurement of marginal costs; some aspects of the environmental costs associated with energy production and use, and some issues related to time differentiated tariffs; the modification of prices to achieve financial targets; and the use of energy prices to achieve income distribution objectives.

  6. The emergence of internet-based virtual private networks in international safeguards

    International Nuclear Information System (INIS)

    2001-01-01

    Full text: The costs associated with secure data transmission can be an obstacle to International Safeguards. Typical communication methods are priced by distance and may include telephone lines, frame relay, and ISDN. It is therefore costly to communicate globally. The growth of the Internet has provided an extensive backbone for global communications; however, the Internet does not provide intrinsic security measures. Combining the Internet with Virtual Private Network technology, which encrypts and authenticates data, creates a secure and potentially cost-effective data transmission path, as well as achieving other benefits such as reliability and scalability. Access to the Internet can be achieved by connecting to a local Internet Service Provider, which can be preferable to installing a static link between two distant points. The cost-effectiveness of the Internet-based Virtual Private Network is dependent on such factors as data amount, current operational costs, and the specifics of the Internet connection, such as user proximity to an Internet Service Provider or existing access to the Internet. This paper will introduce Virtual Private Network technology, the benefits of Internet communication, and the emergence of Internet-based Virtual Private Networks throughout the International Safeguards community. Specific projects to be discussed include: The completed demonstration of secure remote monitoring data transfer via the Internet between STUK in Helsinki, Finland, and the IAEA in Vienna, Austria; The demonstration of secure remote access to IAEA resources by traveling inspectors with Virtual Private Network software loaded on laptops; The proposed Action Sheets between ABACC/DOE and ARN/DOE, which will provide a link between Rio de Janeiro and Buenos Aires; The proposed use at the HIFAR research reactor, located in Australia, to provide remote monitoring data to the IAEA; The use of Virtual Private Networks by JRC, Ispra, Italy.

    The objectives of this study were to determine efficacy of hearing aids in older adults using audiology best practices, to evaluate the efficacy of an alternative over-the-counter (OTC) intervention, and to examine the influence of purchase price on outcomes for both service-delivery models. The design of this study was a single-site, prospective, double-blind placebo-controlled randomized trial with three parallel branches: (a) audiology best practices (AB), (b) consumer decides OTC model (CD), and (c) placebo devices (P). Outcome measures were obtained after a typical 6-week trial period with follow-up 4-week AB-based trial for those initially assigned to CD and P groups. Older adults from the general community were recruited via newspaper and community flyers to participate at a university research clinic. Participants were adults, ages 55-79 years, with mild-to-moderate hearing loss. There were 188 eligible participants: 163 enrolled as a volunteer sample, and 154 completed the intervention. All participants received the same high-end digital mini-behind-the-ear hearing aids fitted bilaterally. AB and P groups received best-practice services from audiologists; differing mainly in use of appropriate (AB) or placebo (P) hearing aid settings. CD participants self-selected their own pre-programmed hearing aids via an OTC model. Primary outcome measure was a 66-item self-report, Profile of Hearing Aid Benefit (Cox & Gilmore, 1990). Secondary outcome measure was the Connected Speech Test (Cox, Alexander, & Gilmore, 1987) benefit. Additional measures of hearing-aid benefit, satisfaction, and usage were also obtained. Per-protocol analyses were performed. AB service-delivery model was found to be efficacious for most of the outcome measures, with moderate or large effect sizes (Cohen's d). CD service-delivery model was efficacious, with similar effect sizes. However, CD group had a significantly (p purchase hearing aids after the trial. Hearing aids are efficacious in

    低油价下受油公司业绩下滑影响,全球石油工程市场规模大幅下降,油服公司收入和利润锐减。为战寒冬、谋发展,西方油服公司纷纷调整发展战略,优化业务结构。具体策略包括压低服务价格、提高效率,注重现金流、削减人工成本,加强科技创新、以技术赢市场,完善业务链、提供一体化服务,实施国际化战略、强强联合,创新运营模式、提升市场竞争力等。建议我国油服公司在低油价下,要以效益为中心,坚持一体化发展,加强创新驱动,强化合作,提升资本运作水平,关注“一带一路”油气合作等。%Influenced by declining business results of oil companies under low oil prices, global oil engineering market shrank signiifcantly, causing the revenue and proift of oilifeld service companies to fall sharply. Western oilifeld service companies adjusted their development strategy and optimized the business structure in the efforts to tide over the dififcult time and seek business development. The concrete strategies include a series of measures to lower service prices, improve service efifciency, pay attention to cash lfow, reduce labor cost, beef up technological innovation, enlarge market share by means of technology, perfect the business chain, provide integration of services, implement internationalization strategy, make cooperation among giants, innovate operational pattern, and improve market competitiveness. Under the current situation of low oil prices, it is proposed that Chinese oilifeld service companies should focus on economic performance, develop themselves on the basis of integration, enhance driving force of innovation, beef up business cooperation, improve capital operational level, and pay attention to the “One Road and One Belt” oil and gas cooperation.

    Cloud computing is changing the ways software is developed and managed in enterprises, which is changing the way of doing business in that dynamically scalable and virtualized resources are regarded as services over the Internet. Traditional manufacturing systems such as supply chain management (SCM), customer relationship management (CRM), and enterprise resource planning (ERP) are often developed case by case. However, effective collaboration between different systems, platforms, programming languages, and interfaces has been suggested by researchers. In cloud-computing-based systems, distributed resources are encapsulated into cloud services and centrally managed, which allows high automation, flexibility, fast provision, and ease of integration at low cost. The integration between physical resources and cloud services can be improved by combining Internet of things (IoT) technology and Software-as-a-Service (SaaS) technology. This study proposes a new approach for developing cloud-based manufacturing systems based on a four-layer SaaS model. There are three main contributions of this paper: (1) enterprises can develop their own cloud-based logistic management information systems based on the approach proposed in this paper; (2) a case study based on literature reviews with experimental results is proposed to verify that the system performance is remarkable; (3) challenges encountered and feedback collected from T Company in the case study are discussed in this paper for the purpose of enterprise deployment.
