Successfully navigating electricity transactions through jurisdictions in the northeast and midwest

Energy Technology Data Exchange (ETDEWEB)

Chappelle, H. [EES Group, Toronto, ON (Canada)

2002-07-01

This presentation described the framework of issues defining the effectiveness of inter-jurisdictional power transactions with reference to open market competition in Ontario and the current FERC initiative affecting transactions with adjacent markets in the United States. The opportunities and risks associated with inter-jurisdictional power transactions were pointed out, along with the interplay between forward and balancing markets. The future of the Regional Transmission Organizations (RTOs) and standard market design were also described. Inter-jurisdictional transactions were described as being a fundamental element of power markets in North America where consumers benefit from reliable supply and cost efficiency. Locational value of the delivered energy is reflected in transparent price which is determined by supply and demand. The efficient balancing markets promote liquid forward markets, as well as investment in power generation and transmission. Price risk is managed through market-based mechanisms by load-serving companies and capable consumers. Opportunities for Ontario buyers include increased reliability, increased competition among suppliers, and market drivers for demand response and innovation. Opportunities for suppliers include additional customers, hedge transactions across jurisdictions, and portfolio strategies. Opportunities for risk managers include broader, more liquid markets for standard products, robust markets for energy-linked commodities, and an increased need for customized, highly-structured financial products. 11 figs.

Transaction costs and sequential bargaining in transferable discharge permit markets.

Netusil, N R; Braden, J B

2001-03-01

Market-type mechanisms have been introduced and are being explored for various environmental programs. Several existing programs, however, have not attained the cost savings that were initially projected. Modeling that acknowledges the role of transactions costs and the discrete, bilateral, and sequential manner in which trades are executed should provide a more realistic basis for calculating potential cost savings. This paper presents empirical evidence on potential cost savings by examining a market for the abatement of sediment from farmland. Empirical results based on a market simulation model find no statistically significant change in mean abatement costs under several transaction cost levels when contracts are randomly executed. An alternative method of contract execution, gain-ranked, yields similar results. At the highest transaction cost level studied, trading reduces the total cost of compliance relative to a uniform standard that reflects current regulations.

Full Text Available This paper aims to contribute to the literature on the geography of external relations of cities. Our overall purpose thereby is to tease out some of the basic principles of alternative approaches to the study of the spatiality of urban systems in the context of economic globalization. To this end, we present an empirical analysis of the urban geography of producer service procurement by 118 of the 300 largest companies in Belgium. The main features of this urban geography of service procurement include (i the dominance of Brussels as a service city ; (ii the existence of overlapping urban spheres of influence ; and (iii the presence of transaction links with foreign cities. The results of our analysis also suggest that, in addition to space- and quality-related decision factors, the intra-firm distribution of decision-making power in multinational firms equally influences the spatiality of transaction links. The relevance of these results is discussed in the context of theorizations of urban systems.Dit artikel levert een bijdrage tot de literatuur die de geografie van externe stedelijke relaties bestudeert.

Principles of Transactional Memory The Theory

CERN Document Server

Guerraoui, Rachid

2010-01-01

Transactional memory (TM) is an appealing paradigm for concurrent programming on shared memory architectures. With a TM, threads of an application communicate, and synchronize their actions, via in-memory transactions. Each transaction can perform any number of operations on shared data, and then either commit or abort. When the transaction commits, the effects of all its operations become immediately visible to other transactions; when it aborts, however, those effects are entirely discarded. Transactions are atomic: programmers get the illusion that every transaction executes all its operati

THE SPECIFICITY OF INTRACOMMUNITY TRANSACTIONS

Full Text Available Considered from the perspective of Romania's accession to the European Union, we can say that starting with 1 January 2007, foreign trade transactions were delimited in relation to the customs borders in intra-Community transactions and international transactions. In this context, the way of conducting these operations is influenced by both the economic and financial features specific to both categories of transactions, that relate to the economic character of the activity, the diversity and specificity of the foreign trade activity, transport of goods, the complexity and regulation of intra-Community and international commercial transactions, and by the specific features of each category of transaction. Starting from the consideration that the economic and financial characteristics of foreign trade activity, specific to intra-Community commercial transactions, have a significant influence in the organization and management of accounting of the entities involved in such transactions, determining in a greater or lesser extent, the way of capitalization of the financial and accounting information in the processes of analysis, decision and control, in this paper we proposed to address the features of intra-Community trade.

This is a final report from a project funded by the U.S. Department of Energy to formulate and test a methodology for valuation of systems where transaction-based mechanisms coordinate the exchange of value between the system’s actors. Today, the principal commodity being exchanged is electrical energy, and such mechanisms are called transactive energy systems. The authors strove to lay a foundation for meaningful valuations of transactive systems in general, and transactive energy systems as a special case. The word valuation is used in many different ways. This report proposes a valuation methodology that is inclusive of many types of valuations. Many will be familiar with cost-benefit valuations, in which both costs and benefits are assessed to determine whether the assets are worth their cost. Another set of valuation methods attempt to optimize an outcome using available resources, as is the case with integrated resource planning. In the end, this report’s methodology was most influenced by and most resembles the integrated-resource-planning approach. Regardless, we wish to enforce the premise that all valuations are comparative and should clearly specify a baseline scenario. A long, annotated list of prior valuation studies and valuation methodologies that influenced this report has been appended to this report. Much research is being conducted today concerning transactive systems, but only a handful of transactive system mechanisms have been formulated and field tested. They are found to be quite diverse, and the documentation of the various mechanisms is uneven in breadth and quality. It is therefore not adequate to simply assert that a valuation scenario includes a transactive system; certain characteristics and qualities of the chosen transactive system mechanism must be defined and stated. The report lists and discusses most of the known transactive system mechanisms. It offers a set of questions that may be used to help specify important

Global diets link environmental sustainability and human health

Science.gov (United States)

Tilman, David; Clark, Michael

2014-11-01

Diets link environmental and human health. Rising incomes and urbanization are driving a global dietary transition in which traditional diets are replaced by diets higher in refined sugars, refined fats, oils and meats. By 2050 these dietary trends, if unchecked, would be a major contributor to an estimated 80 per cent increase in global agricultural greenhouse gas emissions from food production and to global land clearing. Moreover, these dietary shifts are greatly increasing the incidence of type II diabetes, coronary heart disease and other chronic non-communicable diseases that lower global life expectancies. Alternative diets that offer substantial health benefits could, if widely adopted, reduce global agricultural greenhouse gas emissions, reduce land clearing and resultant species extinctions, and help prevent such diet-related chronic non-communicable diseases. The implementation of dietary solutions to the tightly linked diet-environment-health trilemma is a global challenge, and opportunity, of great environmental and public health importance.

Conference Proceedings: Structuring oil and gas property transactions

International Nuclear Information System (INIS)

1999-01-01

The 12 presentations at this conference dealt with issues concerning the legal aspects of oil and gas property transaction agreements. Several issues regarding sales and purchase negotiations of oil and gas property are reviewed and some of the basic principles of contract law are explained. Advantages, disadvantages and opportunities of structuring oil and gas property acquisitions, as well as their tax consequences are also identified. The issue of risk assessment regarding environmental consequences and how public concerns regarding the state of the environment has had an impact on oil and gas transactions, is addressed. Interest in this topic stems from the fact that improved enforcement of existing laws regarding the environment can potentially make purchasers liable for significant costs associated with remediation or clean-up of contaminated properties. refs., tabs., figs

Transactional Network Platform: Applications

Katipamula, Srinivas; Lutes, Robert G.; Ngo, Hung; Underhill, Ronald M.

2013-10-31

In FY13, Pacific Northwest National Laboratory (PNNL) with funding from the Department of Energy’s (DOE’s) Building Technologies Office (BTO) designed, prototyped and tested a transactional network platform to support energy, operational and financial transactions between any networked entities (equipment, organizations, buildings, grid, etc.). Initially, in FY13, the concept demonstrated transactions between packaged rooftop air conditioners and heat pump units (RTUs) and the electric grid using applications or "agents" that reside on the platform, on the equipment, on a local building controller or in the Cloud. The transactional network project is a multi-lab effort with Oakridge National Laboratory (ORNL) and Lawrence Berkeley National Laboratory (LBNL) also contributing to the effort. PNNL coordinated the project and also was responsible for the development of the transactional network (TN) platform and three different applications associated with RTUs. This document describes two applications or "agents" in details, and also summarizes the platform. The TN platform details are described in another companion document.

Transactions in domain-specific information systems

Science.gov (United States)

Zacek, Jaroslav

2017-07-01

Substantial number of the current information system (IS) implementations is based on transaction approach. In addition, most of the implementations are domain-specific (e.g. accounting IS, resource planning IS). Therefore, we have to have a generic transaction model to build and verify domain-specific IS. The paper proposes a new transaction model for domain-specific ontologies. This model is based on value oriented business process modelling technique. The transaction model is formalized by the Petri Net theory. First part of the paper presents common business processes and analyses related to business process modeling. Second part defines the transactional model delimited by REA enterprise ontology paradigm and introduces states of the generic transaction model. The generic model proposal is defined and visualized by the Petri Net modelling tool. Third part shows application of the generic transaction model. Last part of the paper concludes results and discusses a practical usability of the generic transaction model.

An empirical application of transaction-costs theory to organizational design characteristics.

Science.gov (United States)

Williams, S

2000-01-01

The environmental uncertainty component of transaction-costs theory was used to predict the organizational structural characteristics of size (number of employees) and horizontal differentiation (number of vice presidents) using financial and management information from the COMPACT DISCLOSURE data base (which contains the most recent annual and periodic reports for more than 12,000 public companies). Organizations were categorized as low- or high-uncertainty industries according to Dess and Beard's (1984) Dynamism Scale, and net sales volume was controlled. As predicted, high-uncertainty companies had significantly higher horizontal differentiation than low-uncertainty firms, a finding that supports the transaction-costs expectation that organizations may require more departments or personnel to cope with increasing uncertainty. Surprisingly, low-uncertainty firms were found to have significantly more employees than high-uncertainty organizations, which is the opposite of what transaction-costs theory predicts. Possible explanations for this unexpected finding and further potential limitations are discussed.

Simulating water markets with transaction costs

Science.gov (United States)

Erfani, Tohid; Binions, Olga; Harou, Julien J.

2014-06-01

This paper presents an optimization model to simulate short-term pair-wise spot-market trading of surface water abstraction licenses (water rights). The approach uses a node-arc multicommodity formulation that tracks individual supplier-receiver transactions in a water resource network. This enables accounting for transaction costs between individual buyer-seller pairs and abstractor-specific rules and behaviors using constraints. Trades are driven by economic demand curves that represent each abstractor's time-varying water demand. The purpose of the proposed model is to assess potential hydrologic and economic outcomes of water markets and aid policy makers in designing water market regulations. The model is applied to the Great Ouse River basin in Eastern England. The model assesses the potential weekly water trades and abstractions that could occur in a normal and a dry year. Four sectors (public water supply, energy, agriculture, and industrial) are included in the 94 active licensed water diversions. Each license's unique environmental restrictions are represented and weekly economic water demand curves are estimated. Rules encoded as constraints represent current water management realities and plausible stakeholder-informed water market behaviors. Results show buyers favor sellers who can supply large volumes to minimize transactions. The energy plant cooling and agricultural licenses, often restricted from obtaining water at times when it generates benefits, benefit most from trades. Assumptions and model limitations are discussed. This article was corrected on 13 JUN 2014. See the end of the full text for details.

Identifying Bitcoin users by transaction behavior

Science.gov (United States)

Monaco, John V.

2015-05-01

Digital currencies, such as Bitcoin, offer convenience and security to criminals operating in the black marketplace. Some Bitcoin marketplaces, such as Silk Road, even claim anonymity. This claim contradicts the findings in this work, where long term transactional behavior is used to identify and verify account holders. Transaction timestamps and network properties observed over time contribute to this finding. The timestamp of each transaction is the result of many factors: the desire purchase an item, daily schedule and activities, as well as hardware and network latency. Dynamic network properties of the transaction, such as coin flow and the number of edge outputs and inputs, contribute further to reveal account identity. In this paper, we propose a novel methodology for identifying and verifying Bitcoin users based on the observation of Bitcoin transactions over time. The behavior we attempt to quantify roughly occurs in the social band of Newell's time scale. A subset of the Blockchain 230686 is taken, selecting users that initiated between 100 and 1000 unique transactions per month for at least 6 different months. This dataset shows evidence of being nonrandom and nonlinear, thus a dynamical systems approach is taken. Classification and authentication accuracies are obtained under various representations of the monthly Bitcoin samples: outgoing transactions, as well as both outgoing and incoming transactions are considered, along with the timing and dynamic network properties of transaction sequences. The most appropriate representations of monthly Bitcoin samples are proposed. Results show an inherent lack of anonymity by exploiting patterns in long-term transactional behavior.

Transaction costs of farmers’ participation in forest management: Policy implications of payments for environmental services schemes in Vietnam

Directory of Open Access Journals (Sweden)

Areeya Manasboonphempool

2015-11-01

Full Text Available Recent research on payments for environmental services (PES has observed that high transaction costs (TCs are incurred through the implementation of PES schemes and farmer participation. TCs incurred by households are considered to be an obstacle to the participation in and efficiency of PES policies. This study aims to understand transactions related to previous forest plantation programmes and to estimate the actual TCs incurred by farmers who participated in these programmes in a mountainous area of northwestern Vietnam. In addition, this study examines determinants of households’ TCs to test the hypothesis of whether the amount of TCs varies according to household characteristics. Results show that average TCs are not likely to be a constraint for participation since they are about 200,000 VND (USD 10 per household per contract, which is equivalent to one person’s average earnings for about two days of labour. However, TCs amount to more than one-third of the programmes’ benefits, which is relatively high compared to PES programmes in developed countries. This implies that rather than aiming to reduce TCs, an appropriate agenda for policy improvement is to balance the level of TCs with PES programme benefits to enhance the overall attractiveness of afforestation programmes for smallholder farmers. Regression analysis reveals that education, gender and perception towards PES programmes have significant effects on the magnitude of TCs. The analyses also points out the importance of local conditions on the level of TCs, with some unexpected results.

In order to minimize the transaction costs, group lending scheme become  alternative, so that both sides are pay lower transaction costs, and MSEs are able to improve their welfare. This study aims to analyze the credit process and transaction costs incurred on the model of individuals and groups lending and to compare the magnitude of transaction costs on both models. Mixed Method Analysis is used to analyze the component of transaction costs and the magnitude of the transaction cost on both models.These results indicate there are differences in transaction costs incurred on both schemes. In the amount of the transaction costs, the overall group scheme still allows for greater compared to individual schemes and dominated by the cost of the disbursement. Even so, the transaction cost per member group is much smaller than the individual schemes.

Transaction Costs in Housing Markets

OpenAIRE

Ommeren, van, Jos

2008-01-01

According to economic theory, there are no strong reasons to tax (or to subsidise) residential moves, although low levels of taxation may be potentially justified to deal with the presence of externalities and economic stability. This is in contrast to practise in most countries where governments have created strong barriers to moving (transaction taxes, rent control) which induces substantial transaction costs. Likely, the welfare losses due to these government-induced transaction costs are ...

Ring Confidential Transactions

Directory of Open Access Journals (Sweden)

Shen Noether

2016-12-01

Full Text Available This article introduces a method of hiding transaction amounts in the strongly decentralized anonymous cryptocurrency Monero. Similar to Bitcoin, Monero is a cryptocurrency which is distributed through a proof-of-work “mining” process having no central party or trusted setup. The original Monero protocol was based on CryptoNote, which uses ring signatures and one-time keys to hide the destination and origin of transactions. Recently the technique of using a commitment scheme to hide the amount of a transaction has been discussed and implemented by Bitcoin Core developer Gregory Maxwell. In this article, a new type of ring signature, A Multilayered Linkable Spontaneous Anonymous Group signature is described which allows one to include a Pedersen Commitment in a ring signature. This construction results in a digital currency with hidden amounts, origins and destinations of transactions with reasonable efficiency and verifiable, trustless coin generation. The author would like to note that early drafts of this were publicized in the Monero Community and on the #bitcoin-wizards IRC channel. Blockchain hashed drafts are available showing that this work was started in Summer 2015, and completed in early October 2015. An eprint is also available at http://eprint.iacr.org/2015/1098.

Influence of transactive memory on perceived performance, job satisfaction and identification in anaesthesia teams.

Science.gov (United States)

Michinov, E; Olivier-Chiron, E; Rusch, E; Chiron, B

2008-03-01

There is an increasing awareness in the medical community that human factors are involved in effectiveness of anaesthesia teams. Communication and coordination between physicians and nurses seems to play a crucial role in maintaining a good level of performance under time pressure, particularly for anaesthesia teams, who are confronted with uncertainty, rapid changes in the environment, and multi-tasking. The aim of this study was to examine the relationship between a specific form of implicit coordination--the transactive memory system--and perceptions of team effectiveness and work attitudes such as job satisfaction and team identification. A cross-sectional study was conducted among 193 nurse and physician anaesthetists from eight French public hospitals. The questionnaire included some measures of transactive memory system (coordination, specialization, and credibility components), perception of team effectiveness, and work attitudes (Minnesota Job Satisfaction Questionnaire, team identification scale). The questionnaire was designed to be filled anonymously, asking only biographical data relating to sex, age, status, and tenure. Hierarchical multiple regression analyses revealed as predicted that transactive memory system predicted members' perceptions of team effectiveness, and also affective outcomes such as job satisfaction and team identification. Moreover, the results demonstrated that transactive memory processes, and especially the coordination component, were a better predictor of teamwork perceptions than socio-demographic (i.e. gender or status) or contextual variables (i.e. tenure and size of team). These findings provided empirical evidence of the existence of a transactive memory system among real anaesthesia teams, and highlight the need to investigate whether transactive memory is actually linked with objective measures of performance.

The investigation of using 5G millimeter-wave communications links for environmental monitoring

Science.gov (United States)

Han, Congzheng

2017-04-01

There has been significantly increasing recognition that millimeter waves from 30 GHz to 300 GHz as carriers for future 5G cellular networks. This is good for high speed, line-of-sight communication, potentially using very densely deployed infrastructure involving many small cells. High resolution, continuous and accurate monitoring of environmental conditions, such as rainfall and water vapor are of great important to meteorology, hydrology (e.g. flood warning), agriculture, environmental policy (e.g. pollution regulation) and weather forecasting. We have built a 28GHz measurement link at our research institute in central Beijing, China. This work will study the potential of using millimeter wave based wireless links to monitor environmental conditions including rainfall and water vapor.

Anonymous Transactions in Computer Networks

Science.gov (United States)

Dolev, Shlomi; Kopeetsky, Marina

We present schemes for providing anonymous transactions while privacy and anonymity are preserved, providing user anonymous authentication in distributed networks such as the Internet. We first present a practical scheme for anonymous transactions while the transaction resolution is assisted by a Trusted Authority. This practical scheme is extended to a theoretical scheme where a Trusted Authority is not involved in the transaction resolution. Given an authority that generates for each player hard to produce evidence EVID (e. g., problem instance with or without a solution) to each player, the identity of a user U is defined by the ability to prove possession of said evidence. We use Zero-Knowledge proof techniques to repeatedly identify U by providing a proof that U has evidence EVID, without revealing EVID, therefore avoiding identity theft.

Linking ‘toxic outliers’ to environmental justice communities

International Nuclear Information System (INIS)

Collins, Mary B; Munoz, Ian; JaJa, Joseph

2016-01-01

Several key studies have found that a small minority of producers, polluting at levels far exceeding group averages, generate the majority of overall exposure to industrial toxics. Frequently, such patterns go unnoticed and are understudied outside of the academic community. To our knowledge, no research to date has systematically described the scope and extent of extreme variations in industrially based exposure estimates and sought to link inequities in harm produced to inequities in exposure. In an analysis of all permitted industrial facilities across the United States, we show that there exists a class of hyper-polluters—the worst-of-the-worst—that disproportionately expose communities of color and low income populations to chemical releases. This study hopes to move beyond a traditional environmental justice research frame, bringing new computational methods and perspectives aimed at the empirical study of societal power dynamics. Our findings suggest the possibility that substantial environmental gains may be made through selective environmental enforcement, rather than sweeping initiatives. (letter)

Transaction costs of raising energy efficiency. Working paper

In the face of the uncertainties concerning the importance and the actual impacts of anthropogeneous climate change the extent to which measures should be adopted to avoid greenhouse gas emissions (GHG) already today and in the near future is highly controversial. More specifically, part of the debate evolves around the existence and importance of energy saving potentials to reduce CO{sub 2} emissions that may be available at negative net costs, implying that the energy cost savings of one specific technology can actually more than offset the costs of investing into this technology and of using it. This so called 'no-regret' potential would comprise measures that from a pure economic efficiency point of view would be 'worth undertaking whether or not there are climate-related reasons for doing so' (Bruce et al. 1996, p. 271). The existence of the no-regret potential is often denied by arguing, that the economic evaluation of the energy saving potentials did not take into account transaction costs (Grubb et al. 1993). This paper will examine in more detail the concept of transaction costs as it is used in the current debate on no-regret potentials (section 1). Four practical examples are presented to illustrate how transaction costs and their determinants can be identified, measured and possibly influenced (section 2). In order to link the presented cases to modelling based evaluation approaches the implications for cost evaluations of energy saving measures especially in the context of energy system modelling will be shown (section 3).

This document is the second of a two-part report. Part 1 reviewed several demonstrations of transactive control and compared them in terms of their payoff functions, control decisions, information privacy, and mathematical solution concepts. It was suggested in Part 1 that these four listed components should be adopted for meaningful comparison and design of future transactive systems. Part 2 proposes qualitative and quantitative metrics that will be needed to compare alternative transactive systems. It then uses the analysis and design principles from Part 1 while conducting more in-depth analysis of two transactive demonstrations: the American Electric Power (AEP) gridSMART Demonstration, which used a double –auction market mechanism, and a consensus method like that used in the Pacific Northwest Smart Grid Demonstration. Ultimately, metrics must be devised and used to meaningfully compare alternative transactive systems. One significant contribution of this report is an observation that the decision function used for thermostat control in the AEP gridSMART Demonstration has superior performance if its decision function is recast to more accurately reflect the power that will be used under for thermostatic control under alternative market outcomes.

A systematic review was conducted by a multidisciplinary team to analyze qualitatively best available scientific evidence on the effect of agricultural intensification and environmental changes on the risk of zoonoses for which there are epidemiological interactions between wildlife and livestock. The study found several examples in which agricultural intensification and/or environmental change were associated with an increased risk of zoonotic disease emergence, driven by the impact of an expanding human population and changing human behavior on the environment. We conclude that the rate of future zoonotic disease emergence or reemergence will be closely linked to the evolution of the agriculture-environment nexus. However, available research inadequately addresses the complexity and interrelatedness of environmental, biological, economic, and social dimensions of zoonotic pathogen emergence, which significantly limits our ability to predict, prevent, and respond to zoonotic disease emergence.

Multi-period fuzzy mean-semi variance portfolio selection problem with transaction cost and minimum transaction lots using genetic algorithm

Mohammad Ali Barati

2016-04-01

Full Text Available Multi-period models of portfolio selection have been developed in the literature with respect to certain assumptions. In this study, for the first time, the portfolio selection problem has been modeled based on mean-semi variance with transaction cost and minimum transaction lots considering functional constraints and fuzzy parameters. Functional constraints such as transaction cost and minimum transaction lots were included. In addition, the returns on assets parameters were considered as trapezoidal fuzzy numbers. An efficient genetic algorithm (GA was designed, results were analyzed using numerical instances and sensitivity analysis were executed. In the numerical study, the problem was solved based on the presence or absence of each mode of constraints including transaction costs and minimum transaction lots. In addition, with the use of sensitivity analysis, the results of the model were presented with the variations of minimum expected rate of programming periods.

2001-01-01

The QA programme is reviewed for the environmental compliance tests of commercial off-the-shelf (COTS) components for the CMS Tracker Optical link system. These environmental tests will take place in the pre-production and final production phases of the project and will measure radiation resistance, component lifetime, and sensitivity to magnetic fields. The evolution of the programme from small-scale prototype tests to the final pre-production manufacturing tests is outlined and the main environmental effects expected for optical links operating within the Tracker are summarised. A special feature of the environmental QA programme is the plan for Advance Validation Tests (AVT's) developed in close collaboration with the various industrial partners. AVT procedures involve validation of a relatively small set of basic samples in advance of the full production of the corresponding batch of devices. Only those lots that have been confirmed as sufficiently rad-tolerant will be purchased and used in the final prod...

Accountable Care Organizations and Transaction Cost Economics.

Science.gov (United States)

Mick, Stephen S Farnsworth; Shay, Patrick D

2016-12-01

Using a Transaction Cost Economics (TCE) approach, this paper explores which organizational forms Accountable Care Organizations (ACOs) may take. A critical question about form is the amount of vertical integration that an ACO may have, a topic central to TCE. We posit that contextual factors outside and inside an ACO will produce variable transaction costs (the non-production costs of care) such that the decision to integrate vertically will derive from a comparison of these external versus internal costs, assuming reasonably rational management abilities. External costs include those arising from environmental uncertainty and complexity, small numbers bargaining, asset specificity, frequency of exchanges, and information "impactedness." Internal costs include those arising from human resource activities including hiring and staffing, training, evaluating (i.e., disciplining, appraising, or promoting), and otherwise administering programs. At the extreme, these different costs may produce either total vertical integration or little to no vertical integration with most ACOs falling in between. This essay demonstrates how TCE can be applied to the ACO organization form issue, explains TCE, considers ACO activity from the TCE perspective, and reflects on research directions that may inform TCE and facilitate ACO development. © The Author(s) 2016.

Optimizing Concurrent M3-Transactions: A Fuzzy Constraint Satisfaction Approach

Directory of Open Access Journals (Sweden)

Peng LI

2004-10-01

Full Text Available Due to the high connectivity and great convenience, many E-commerce application systems have a high transaction volume. Consequently, the system state changes rapidly and it is likely that customers issue transactions based on out-of-date state information. Thus, the potential of transaction abortion increases greatly. To address this problem, we proposed an M3-transaction model. An M3-transaction is a generalized transaction where users can issue their preferences in a request by specifying multiple criteria and optional data resources simultaneously within one transaction. In this paper, we introduce the transaction grouping and group evaluation techniques. We consider evaluating a group of M3-transactions arrived to the system within a short duration together. The system makes optimal decisions in allocating data to transactions to achieve better customer satisfaction and lower transaction failure rate. We apply the fuzzy constraint satisfaction approach for decision-making. We also conduct experimental studies to evaluate the performance of our approach. The results show that the M3-transaction with group evaluation is more resilient to failure and yields much better performance than the traditional transaction model.

Remedial transactions curtailment via optimization

Maksimović Viktor

2009-01-01

Full Text Available The new method developed in this paper is aiming at transmission congestion management (CM. The new, Optimal Transactions Management method (OTM, is based on linear programming (LP, DC load flow (DCLF and linear security constraints. The OTM method is embedded in Available Transfer Capabilities (ATCs and Power Transfer Distribution Factors (PTDFs definitions' environment. Well-suited for both preventive and corrective modes of operation, the OTM method aids transmission system operator in running a congested power system network, where congestions are due to transactions. Potential congestion threat is solved by finding the 'culprit' transaction and its optimal reduction. Besides the proposed downsizing of scheduled and/or committed transactions, controls of the OTM method also include redispatching of generation and load levels. The task is to establish a system state without constraint violations. To ensure the feasible network solution, both DC and AC power flows are used. The common 5 nodes/7 lines Ward&Hale sample power system is used to clarify the OTM method. Besides, six other power system networks including the real-life power system network of Serbia, Macedonia and Montenegro (part of the South East Europe - SEE grid are used to test remedial potentials and CPU-time performances of the method. The 24-hour daily demand diagram is used with all test networks to study the effects of transactions as they are being superimposed to the regional grid. The remedial, transactions-curtailing OTM method is found well suited for market-related analyses precluding the hour-ahead, the day-ahead dispatch, as well as the real-time generation dispatch. It could also suit for the novel, Day Ahead Congestion Forecast (DACF procedure used in power markets. .

Distributed Management of Concurrent Web Service Transactions

Business processes involve dynamic compositions of interleaved tasks. Therefore, ensuring reliable transactional processing of Web services is crucial for the success of Web service-based B2B and B2C applications. But the inherent autonomy and heterogeneity of Web services render the applicability...... of conventional ACID transaction models for Web services far from being straightforward. Current Web service transaction models relax the isolation property and rely on compensation mechanisms to ensure atomicity of business transactions in the presence of service failures. However, ensuring consistency...... in the open and dynamic environment of Web services, where interleaving business transactions enter and exit the system independently, remains an open issue. In this paper, we address this problem and propose an architecture that supports concurrency control on the Web services level. An extension...

Austrian Economics and the Transaction Cost Approach to the Firm

Directory of Open Access Journals (Sweden)

Nicolai J. Foss

2009-10-01

Full Text Available As the transaction cost theory of the firm was taking shape in the 1970s, another important movement in economics was emerging: a revival of the ‘Austrian’ tradition in economic theory associated with such economists as Ludwig von Mises and F. A. Hayek (1973; Dolan, 1976; Spadaro, 1978. As Oliver Williamson has pointed out, Austrian economics is among the diverse sources for transaction cost economics. In particular, Williamson frequently cites Hayek (e.g., Williamson, 1985, p. 8; 1991, p. 162, particularly Hayek’s emphasis on adaptation as a key problem of economic organisation (Hayek, 1945. Following Williamson’s lead, a reference to Hayek’s ‘The Use of Knowledge in Society’ (Hayek, 1945 has become almost mandatory in discussions of economic organisation (e.g., Ricketts, 1987, p. 59; Milgrom and Roberts, 1992, p. 56; Douma and Schreuder 1991, p. 9. However, there are many other potential links between Austrian and transaction cost economics that have not been explored closely and exploited.This article argues that characteristically Austrian ideas about property, entrepreneurship, economic calculation, tacit knowledge, and the temporal structure of capital have important implications for theories of economic organisation, transaction cost economics in particular. Austrian economists have not, however, devoted substantial attention to the theory of the firm, preferring to focus on business-cycle theory, welfare economics, political economy, comparative economic systems, and other areas. Until recently the theory of the firm was an almost completely neglected area in Austrian economics, but over the last decade, a small Austrian literature on the firm has emerged. While these works cover a wide variety of theoretical and applied topics, their authors share the view that Austrian insights have something to offer students of firm organisation.

BitCoin transactions are malleable in a sense that given a transaction an adversary can easily construct an equivalent transaction which has a different hash. This can pose a serious problem in some BitCoin distributed contracts in which changing a transaction's hash may result in the protocol disruption and a financial loss. The problem mostly concerns protocols, which use a "refund" transaction to withdraw a deposit in a case of the protocol interruption. In this short note, we show a gener...

Foreign exchange transaction exposure of enterprises in Serbia

Directory of Open Access Journals (Sweden)

Bogićević Jasmina

2016-01-01

Full Text Available Enterprises involved in international business face transaction exposure to foreign exchange risk. This type of exposure occurs when an enterprise trades, borrows, or lеnds in foreign currency. Transaction exposure has a direct effect on an enterprise’s financial position and profitability. It is one of the three forms of exposure to exchange rate fluctuations, the other two being translation exposure and operating exposure. The aim of this paper is to assess the transaction exposure of enterprises in Serbia operating internationally. In addition to identifying and measuring transaction exposure, this paper explores the practical importance that enterprises in Serbia attach to management of this type of foreign exchange risk. We do not find significant differences between domestic and foreign enterprises in their choice of the type of foreign exchange risk exposure to manage. Although transaction exposure is the most managed type of foreign exchange risk, research has shown that, compared to foreign businesses, Serbian enterprises do not use sufficient protective measures to minimize the negative impact of this type of exposure on their cash flows and profitability. We expected that there would be a statistically significant dependence between the volume of enterprises’ foreign currency transactions and the level of applied transaction exposure management practices. However, the results of our research, based on a sample of enterprises in Serbia operating internationally, show that transaction exposure management practices can be influenced by factors other than the level of an enterprise’s foreign currency transactions, such as the enterprise’s country of origin.

The Influence of an External Transaction on a BPEL Scope

Science.gov (United States)

Kopp, Oliver; Mietzner, Ralph; Leymann, Frank

Business processes constitute an integral part of today's IT applications. They contain transactions as essential building blocks to ensure integrity and all-or-nothing behavior. The Business Process Execution Language is the dominant standard for modeling and execution of business processes in a Web service environment. BPEL itself contains a transaction model based on compensation, that describes the (local) transactions in a business process. The WS-Coordination framework deals with (external) transactions between Web services and is used to define the transaction behavior between a BPEL process and its partners. In this paper, we investigate how external transactions between Web services interrelate with local transactions of BPEL.

Terrestrial environmental systems are characterised by numerous feedback links between their different compartments. However, scientific research is organized into disciplines that focus on processes within the respective compartments rather than on interdisciplinary links. Major feedback mechanisms between compartments might therefore have been systematically overlooked so far. Without identifying these gaps, initiatives on future comprehensive environmental monitoring schemes and experimental platforms might fail. We performed a comprehensive overview of feedbacks between compartments currently represented in environmental sciences and explores to what degree missing links have already been acknowledged in the literature. We focused on process models as they can be regarded as repositories of scientific knowledge that compile findings of numerous single studies. In total, 118 simulation models from 23 model types were analysed. Missing processes linking different environmental compartments were identified based on a meta-review of 346 published reviews, model intercomparison studies, and model descriptions. Eight disciplines of environmental sciences were considered and 396 linking processes were identified and ascribed to the physical, chemical or biological domain. There were significant differences between model types and scientific disciplines regarding implemented interdisciplinary links. The most wide-spread interdisciplinary links were between physical processes in meteorology, hydrology and soil science that drive or set the boundary conditions for other processes (e.g., ecological processes). In contrast, most chemical and biological processes were restricted to links within the same compartment. Integration of multiple environmental compartments and interdisciplinary knowledge was scarce in most model types. There was a strong bias of suggested future research foci and model extensions towards reinforcing existing interdisciplinary knowledge rather than

Dynamic Self-Healing Mechanism for Transactional Business Process

Directory of Open Access Journals (Sweden)

Yuhai Zhao

2015-01-01

Full Text Available It is clear that transactional behavior consistency is a prerequisite and basis for construction of a reliable services-based business application. However, in previous works, maintaining transactional consistency during exception handling was ignored. Maintaining transactional consistency requires functionality for rolling back some operations and revoking uploaded data. Replacing only the failed service will eventually lead to overall business application failure. In this study, we take fully into account the behavioral consistency of transactional services and propose two effective self-healing mechanisms for service-based applications. If a service enters into potential failure condition, a rescheduling mechanism is triggered to maintain consistent transactional behavior and to ensure reliable execution; if a service fails during execution, the compensation operation is triggered and the system will take action to ensure transactional behavior consistency. Meanwhile, cost-benefit analysis with compensation support is proposed to minimize the dynamic reselection cost. Finally, the experimental analysis shows that the proposed strategies can effectively guarantee the reliability of Web-based applications system.

A transaction assessment method for allocation of transmission services

Science.gov (United States)

Banunarayanan, Venkatasubramaniam

The purpose of this research is to develop transaction assessment methods for allocating transmission services that are provided by an area/utility to power transactions. Transmission services are the services needed to deliver, or provide the capacity to deliver, real and reactive power from one or more supply points to one or more delivery points. As the number of transactions increase rapidly in the emerging deregulated environment, accurate quantification of the transmission services an area/utility provides to accommodate a transaction is becoming important, because then appropriate pricing schemes can be developed to compensate for the parties that provide these services. The Allocation methods developed are based on the "Fair Resource Allocation Principle" and they determine for each transaction the following: the flowpath of the transaction (both real and reactive power components), generator reactive power support from each area/utility, real power loss support from each area/utility. Further, allocation methods for distributing the cost of relieving congestion on transmission lines caused by transactions are also developed. The main feature of the proposed methods is representation of actual usage of the transmission services by the transactions. The proposed method is tested extensively on a variety of systems. The allocation methods developed in this thesis for allocation of transmission services to transactions is not only useful in studying the impact of transactions on a transmission system in a multi-transaction case, but they are indeed necessary to meet the criteria set forth by FERC with regard to pricing based on actual usage. The "consistency" of the proposed allocation methods has also been investigated and tested.

Disincentives to voluntary transactions

International Nuclear Information System (INIS)

Anon.

1991-01-01

Current legal, regulatory and institutional standards and practices provide several disincentives for a utility wishing to engage in voluntary wheeling transactions, and are discussed here. These disincentives largely arise from the fact that regulation, like the transmission system itself, is based on the notion of integrated utilities engaging in transactions largely for reliability reasons. Factors which fall into this category are: a pricing regime based on embedded costs, the ratemaking treatment of revenues derived from coordination and transmission services, and several provisions in legislation and FERC regulations

Full Text Available Transaction-cost models in continuous-time markets are considered. Given that investors decide to buy or sell at certain time instants, we study the existence of trading strategies that reach a certain final wealth level in continuous-time markets, under the assumption that transaction costs, built in certain recommended ways, have to be paid. Markets prove to behave in manners that resemble those of complete ones for a wide variety of transaction-cost types. The results are important, but not exclusively, for the pricing of options with transaction costs.

This document proposes a framework concept to achieve the objectives of raising buildings’ efficiency and energy savings potential benefitting building owners and operators. We call it a transaction-based framework, wherein mutually-beneficial and cost-effective market-based transactions can be enabled between multiple players across different domains. Transaction-based building controls are one part of the transactional energy framework. While these controls realize benefits by enabling automatic, market-based intra-building efficiency optimizations, the transactional energy framework provides similar benefits using the same market -based structure, yet on a larger scale and beyond just buildings, to the society at large.

We develop a microeconomic production model that takes into account transaction costs and networks. Using a data set of 384 Polish farms, we empirically estimate this model......We argue that in the presence of transaction costs, observed productivity measures may in many cases understate the true productivity, as production data seldom distinguish between resources entering the production process and resources of a similar type that are sacrificed for transaction costs....... Hence, both the absolute productivity measures and, more importantly, the productivity ranking will be distorted. A major driver of transaction costs is poor access to information and contract enforcement assistance. Social networks often catalyse information exchange as well as generate trust...

The transactional interpretation of quantum mechanics

Science.gov (United States)

Cramer, John G.

2001-06-01

The transactional interpretation of quantum mechanics [1] was originally published in 1986 and is now about 14 years old. It is an explicitly nonlocal and Lorentz invariant alternative to the Copenhagen interpretation. It interprets the formalism for a quantum interaction as describing a "handshake" between retarded waves (ψ) and advanced waves (ψ*) for each quantum event or "transaction" in which energy, momentum, angular momentum, and other conserved quantities are transferred. The transactional interpretation offers the advantages that (1) it is actually "visible" in the formalism of quantum mechanics, (2) it is economical, involving fewer independent assumptions than its rivals, (3) it is paradox-free, resolving all of the paradoxes of standard quantum theory including nonlocality and wave function collapse, (4) it does not give a privileged role to observers or measurements, and (5) it permits the visualization of quantum events. We will review the transactional interpretation and some of its applications to "quantum paradoxes."

Papers of the 3. annual Canadian Institute conference on interjurisdictional power transactions

Leaders from the electric power industry in both Canada and the United States presented their views on a wide range of topics dealing with interjurisdictional power transactions. Participants presented ideas on how to prepare for the Federal Energy Regulatory Commission's (FERC) proposed new Standard Market Design. They also addressed the issue of how to overcome congestion for seamless power transactions between Canada and the Northeast. The way in which some companies and regions are preparing themselves for locational marginal pricing were also presented. Other topics included the state of the market power mitigation in Ontario, and increased trade potential within Ontario, Quebec and Atlantic Canada. Updates on the Lake Erie Link project were included along with a discussion on the expected impact it may have on trade capacity between Canada and the United States. The conference featured 18 presentations, of which 7 have been indexed separately for inclusion in this database. refs., tabs., figs

Absorbers in the Transactional Interpretation of Quantum Mechanics

Science.gov (United States)

Boisvert, Jean-Sébastien; Marchildon, Louis

2013-03-01

The transactional interpretation of quantum mechanics, following the time-symmetric formulation of electrodynamics, uses retarded and advanced solutions of the Schrödinger equation and its complex conjugate to understand quantum phenomena by means of transactions. A transaction occurs between an emitter and a specific absorber when the emitter has received advanced waves from all possible absorbers. Advanced causation always raises the specter of paradoxes, and it must be addressed carefully. In particular, different devices involving contingent absorbers or various types of interaction-free measurements have been proposed as threatening the original version of the transactional interpretation. These proposals will be analyzed by examining in each case the configuration of absorbers and, in the special case of the so-called quantum liar experiment, by carefully following the development of retarded and advanced waves through the Mach-Zehnder interferometer. We will show that there is no need to resort to the hierarchy of transactions that some have proposed, and will argue that the transactional interpretation is consistent with the block-universe picture of time.

ACCOUNTING TREATMENTS SPECIFIC TO COUNTERPART COMMERCIAL TRANSACTIONS

Directory of Open Access Journals (Sweden)

Lucia PALIU - POPA

2010-12-01

Full Text Available Given the lack of availability of funds in foreign currency, felt in many countries, especially in the developing and developed countries and the economic or financial crisis in the global foreign exchange, counterpart commercial transactions were imposed as a “disarming” condition of the international trade. In the counterpart a purchase transaction is combined with a sale transaction, an import with an export in order to ensure balanced trade between the partners, trade that involves eliminating or reducing the currency as a payment source and its replacement with trade of goods and services. Thus, in the context of an acute need to export of greatly industrialized countries, where the overproduction phenomenon tends to have a chronic character, the counterpart has become a highly complex and sustainable phenomenon, which has seen a steady increase in the volume of amounts, with a geographical area and large variety of forms and mechanisms of implementation. Based on the characteristics and structure of counterpart transactions, we shall describe in this paper the accounting models specific to international trade, as part of the combined foreign trade transactions without neglecting the tax treatments that influence the entry in the accounts

Transactional processes in the development of adult personality disorder symptoms.

Science.gov (United States)

Carlson, Elizabeth A; Ruiz, Sarah K

2016-08-01

The development of adult personality disorder symptoms, including transactional processes of relationship representational and behavioral experience from infancy to early adolescence, was examined using longitudinal data from a risk sample (N = 162). Significant preliminary correlations were found between early caregiving experience and adult personality disorder symptoms and between representational and behavioral indices across time and adult symptomatology. Significant correlations were also found among diverse representational assessments (e.g., interview, drawing, and projective narrative) and between concurrent representational and observational measures of relationship functioning. Path models were analyzed to investigate the combined relations of caregiving experience in infancy; relationship representation and experience in early childhood, middle childhood, and early adolescence; and personality disorder symptoms in adulthood. The hypothesized model representing interactive contributions of representational and behavioral experience represented the data significantly better than competing models representing noninteractive contributions. Representational and behavioral indicators mediated the link between early caregiving quality and personality disorder symptoms. The findings extend previous studies of normative development and support an organizational developmental view that early relationship experiences contribute to socioemotional maladaptation as well as adaptation through the progressive transaction of mutually informing expectations and experience.

Utility-preserving transaction data anonymization with low information loss.

Science.gov (United States)

Loukides, Grigorios; Gkoulalas-Divanis, Aris

2012-08-01

Transaction data record various information about individuals, including their purchases and diagnoses, and are increasingly published to support large-scale and low-cost studies in domains such as marketing and medicine. However, the dissemination of transaction data may lead to privacy breaches, as it allows an attacker to link an individual's record to their identity. Approaches that anonymize data by eliminating certain values in an individual's record or by replacing them with more general values have been proposed recently, but they often produce data of limited usefulness. This is because these approaches adopt value transformation strategies that do not guarantee data utility in intended applications and objective measures that may lead to excessive data distortion. In this paper, we propose a novel approach for anonymizing data in a way that satisfies data publishers' utility requirements and incurs low information loss. To achieve this, we introduce an accurate information loss measure and an effective anonymization algorithm that explores a large part of the problem space. An extensive experimental study, using click-stream and medical data, demonstrates that our approach permits many times more accurate query answering than the state-of-the-art methods, while it is comparable to them in terms of efficiency.

Transactional Memory (TM) has received significant attention recently as a mechanism to reduce the complexity of shared memory programming. We explore the potential of TM to improve OpenMP applications. We combine a software TM (STM) system to support transactions with an OpenMP implementation to start thread teams and provide task and loop-level parallelization. We apply this system to two application scenarios that reflect realistic TM use cases. Our results with this system demonstrate that even with the relatively high overheads of STM, transactions can outperform OpenMP critical sections by 10%. Overall, our study demonstrates that extending OpenMP to include transactions would ease programming effort while allowing improved performance.

This work presents a systemic top-down visualization of Bitcoin transaction activity to explore dynamically generated patterns of algorithmic behavior. Bitcoin dominates the cryptocurrency markets and presents researchers with a rich source of real-time transactional data. The pseudonymous yet public nature of the data presents opportunities for the discovery of human and algorithmic behavioral patterns of interest to many parties such as financial regulators, protocol designers, and security analysts. However, retaining visual fidelity to the underlying data to retain a fuller understanding of activity within the network remains challenging, particularly in real time. We expose an effective force-directed graph visualization employed in our large-scale data observation facility to accelerate this data exploration and derive useful insight among domain experts and the general public alike. The high-fidelity visualizations demonstrated in this article allowed for collaborative discovery of unexpected high frequency transaction patterns, including automated laundering operations, and the evolution of multiple distinct algorithmic denial of service attacks on the Bitcoin network.

Transactive energy refers to the combination of economic and control techniques to improve grid reliability and efficiency. The fundamental purpose of transactive energy management is to seamlessly coordinate the operation of large numbers of new intelligent assets—such as distributed solar, energy storage and responsive building loads—to provide the flexibility needed to operate the power grid reliably and at minimum cost, particularly one filled with intermittent renewable generation such as the Pacific Northwest. It addresses the key challenge of providing smooth, stable, and predictable “control” of these assets, despite the fact that most are neither owned nor directly controlled by the power grid. The Clean Energy and Transactive Campus (CETC) work described in this report was done as part of a Cooperative Research and Development Agreement (CRADA) between the U.S. Department of Energy’s Pacific Northwest National Laboratory (PNNL) and the Washington State Department of Commerce (Commerce) through the Clean Energy Fund (CEF). The project team consisted of PNNL, the University of Washington (UW) and Washington State University (WSU), to connect the PNNL, UW, and WSU campuses to form a multi-campus testbed for transaction-based energy management—transactive—solutions. Building on the foundational transactive system established by the Pacific Northwest Smart Grid Demonstration (PNWSGD), the purpose of the project was to construct the testbed as both a regional flexibility resource and as a platform for research and development (R&D) on buildings/grid integration and information-based energy efficiency. This report provides a summary of the various tasks performed under the CRADA.

International audience; Transactional database management systems (DBMS) have been successful at supporting traditional transaction processing workloads. However, web-based applications that tend to generate huge numbers of concurrent business operations are pushing DBMS performance over their limits, thus threatening overall system availability. Then, a crucial question is how to test DBMS performance under heavy workload conditions. Answering this question requires a testing methodology to ...

The Value Added Tax Implications of Illegal Transactions

Directory of Open Access Journals (Sweden)

SP van Zyl

2011-01-01

Full Text Available In the case of MP Finance Group CC (In Liquidation v CSARS the High Court of Appeal ruled that income "received by" a taxpayer from illegal gains will be taxable in the hands of the taxpayer. This article explores whether or not the decision in the MP Finance-case (and preceding cases on the taxation of illegal receipts can be applied to determine if illegal transactions are subject to VAT and moreover if a trader in illegal goods and services should register as a VAT vendor. Although strictly speaking no analogy can be drawn between the charging provisions for income tax and VAT, it is clear that in the determination of the taxability of illegal income, the courts applied the principle of tax neutrality. In terms of the principle of tax neutrality, taxes are not concerned with the legality or illegality of a transaction, but rather with whether the transaction complies with the requirements for it to be taxed or not. That said, the European Court of Justice has a different approach in applying this principle. According to the European Court of Justice where the intrinsic nature of the goods excludes it from the commercial arena (like narcotic drugs it should not be subject to VAT, but where the goods compete with a legal market it must be subject to VAT. Charging VAT on illegal transactions might give the impression that government benefits from criminal activities. However, if illegal transactions are not subject to VAT the trader in illegal goods will benefit as his products will be 14% cheaper than his rival’s. Is this necessarily a moral dilemma? In conclusion three arguments can be deduced on the question if illegal transactions should be subject to VAT:1. Illegal transactions should not be taxed at all. Illegal goods or services fall outside the sphere of the application of the charging provision in section 7(1 of the VAT Act. Moreover, taxing illegal transactions lends a quasi-validity to the contract and gives the impression that

Möbius: Trustless Tumbling for Transaction Privacy

Directory of Open Access Journals (Sweden)

Meiklejohn Sarah

2018-04-01

Full Text Available Cryptocurrencies allow users to securely transfer money without relying on a trusted intermediary, and the transparency of their underlying ledgers also enables public verifiability. This openness, however, comes at a cost to privacy, as even though the pseudonyms users go by are not linked to their real-world identities, all movement of money among these pseudonyms is traceable. In this paper, we present Möbius, an Ethereum-based tumbler or mixing service. Möbius achieves strong notions of anonymity, as even malicious senders cannot identify which pseudonyms belong to the recipients to whom they sent money, and is able to resist denial-of-service attacks. It also achieves a much lower off-chain communication complexity than all existing tumblers, with senders and recipients needing to send only two initial messages in order to engage in an arbitrary number of transactions.

"Women's bodies are shops": beliefs about transactional sex and implications for understanding gender power and HIV prevention in Tanzania.

Science.gov (United States)

Wamoyi, Joyce; Fenwick, Angela; Urassa, Mark; Zaba, Basia; Stones, William

2011-02-01

Although transactional sex has been linked to undesirable sexual health outcomes, there is a lack of clarity as to the meaning of the practice, which appears to extend beyond behaviors related to women's economic circumstances. This article explored the perspectives of parents and unmarried young people on motivations for, and beliefs about, transactional sex in rural Tanzania using an ethnographic research design. Data collection involved 17 focus groups and 46 in-depth interviews with young people aged 14-24 years and parents/caregivers. Transactional sex was widely accepted by both parents and young people. Male parents equated sexual exchange to buying meat from a butcher and interpreted women's demand for exchange before sex with personal power. Young men referred to transactional sex as the easiest way to get a woman to satisfy their sexual desires while also proving their masculinity. Young women perceived themselves as lucky to be created women as they could exploit their sexuality for pleasure and material gain. They felt men were stupid for paying for "goods" (vagina) they could not take away. Mothers were in agreement with their daughters. Although young women saw exploitation of the female body in positive terms, they were also aware of the health risks but ascribed these to bad luck. Interventions aimed at tackling transactional sex in the interests of women's empowerment and as a strategy for HIV prevention need to understand the cultural beliefs associated with the practice that may make it thrive despite the known risks.

VOLTTRON Lite: Integration Platform for the Transactional Network

Energy Technology Data Exchange (ETDEWEB)

Haack, Jereme N.; Katipamula, Srinivas; Akyol, Bora A.; Lutes, Robert G.

2013-10-31

In FY13, Pacific Northwest National Laboratory (PNNL) with funding from the Department of Energy’s (DOE’s) Building Technologies Office (BTO) designed, prototyped and tested a transactional network platform. The platform is intended to support energy, operational and financial transactions between any networked entities (equipment, organizations, buildings, grid, etc.). Initially, in FY13, the concept demonstrated transactions between packaged rooftop units (RTUs) and the electric grid using applications or “agents” that reside on the platform, on the equipment, on local building controller or in the Cloud. This document describes the core of the transactional network platform, the Volttron Lite™ software and associated services hosted on the platform. Future enhancements are also discussed. The appendix of the document provides examples of how to use the various services hosted on the platform.

Transaction-Based Controls for Building-Grid Integration: VOLTTRON™

2015-07-01

The U.S. Department of Energy’s (DOE’s) Building Technologies Office (BTO) is supporting the development of a “transactional network” concept that supports energy, operational, and financial transactions between building systems (e.g., rooftop units -- RTUs), and the electric power grid using applications, or 'agents', that reside either on the equipment, on local building controllers, or in the Cloud. The transactional network vision is delivered using a real-time, scalable reference platform called VOLTTRON that supports the needs of the changing energy system. VOLTTRON is an agent execution and an innovative distributed control and sensing software platform that supports modern control strategies, including agent-based and transaction-based controls. It enables mobile and stationary software agents to perform information gathering, processing, and control actions.

. Hence, both the absolute productivity measures and, more importantly, the productivity ranking will be distorted. A major driver of transaction costs is poor access to information and contract enforcement assistance. Social networks often catalyse information exchange as well as generate trust...... and support. Hence, we use measures of a firm’s access to social networks as a proxy for the transaction costs the firm faces. We develop a microeconomic production model that takes into account transaction costs and networks. Using a data set of 384 Polish farms, we empirically estimate this model...... and compare different parametric, semiparametric, and nonparametric model specifications. Our results generally support our hypothesis. Especially, large trading networks and dense household networks have a positive influence on a farm’s productivity. Furthermore, our results indicate that transaction costs...

Transactional relations between caregiving stress, executive functioning, and problem behavior from early childhood to early adolescence

Developmental psychopathologists face the difficult task of identifying the environmental conditions that may contribute to early childhood behavior problems. Highly stressed caregivers can exacerbate behavior problems, while children with behavior problems may make parenting more difficult and increase caregiver stress. Unknown is: (1) how these transactions originate, (2) whether they persist over time to contribute to the development of problem behavior and (3) what role resilience factors, such as child executive functioning, may play in mitigating the development of problem behavior. In the present study, transactional relations between caregiving stress, executive functioning, and behavior problems were examined in a sample of 1,388 children with prenatal drug exposures at three developmental time points: early childhood (birth-age 5), middle childhood (ages 6 to 9), and early adolescence (ages 10 to 13). Transactional relations differed between caregiving stress and internalizing versus externalizing behavior. Targeting executive functioning in evidence-based interventions for children with prenatal substance exposure who present with internalizing problems and treating caregiving psychopathology, depression, and parenting stress in early childhood may be particularly important for children presenting with internalizing behavior.

Environmental conditions can modulate the links among oxidative stress, age, and longevity.

Science.gov (United States)

Marasco, Valeria; Stier, Antoine; Boner, Winnie; Griffiths, Kate; Heidinger, Britt; Monaghan, Pat

2017-06-01

Understanding the links between environmental conditions and longevity remains a major focus in biological research. We examined within-individual changes between early- and mid-adulthood in the circulating levels of four oxidative stress markers linked to ageing, using zebra finches (Taeniopygia guttata): a DNA damage product (8-hydroxy-2'-deoxyguanosine; 8-OHdG), protein carbonyls (PC), non-enzymatic antioxidant capacity (OXY), and superoxide dismutase activity (SOD). We further examined whether such within-individual changes differed among birds living under control (ad lib food) or more challenging environmental conditions (unpredictable food availability), having previously found that the latter increased corticosterone levels when food was absent but improved survival over a three year period. Our key findings were: (i) 8-OHdG and PC increased with age in both environments, with a higher increase in 8-OHdG in the challenging environment; (ii) SOD increased with age in the controls but not in the challenged birds, while the opposite was true for OXY; (iii) control birds with high levels of 8-OHdG died at a younger age, but this was not the case in challenged birds. Our data clearly show that while exposure to the potentially damaging effects of oxidative stress increases with age, environmental conditions can modulate the pace of this age-related change.

Parent-offspring transaction: Mechanisms and the value of within family designs.

Science.gov (United States)

Jenkins, Jennifer M; McGowan, Patrick; Knafo-Noam, Ariel

2016-01-01

This article is part of a Special Issue "Parental Care". Parenting is best understood as a transactional process between parents and their offspring. Each responds to cues in the other, adapting their own behavior to that of their partner. One of the goals of parenting research in the past twenty years has been to untangle reciprocal processes between parents and children in order to specify what comes from the child (child effects) and what comes from the parent (parent effects). Child effects have been found to relate to genetic, pre and perinatal, family-wide, and child-specific environmental influences. Parent effects relate to stresses in the current context (e.g. financial strain, marital conflict), personality and ethnicity but also to adverse childhood experiences (e.g. parental mental health and substance abuse, poverty, divorce). Rodent models have allowed for the specification of biological mechanisms in parent and child effects, including neurobiological and genomic mechanisms, and of the causal role of environmental experience on outcomes for offspring through random assignment of offspring-mother groupings. One of the methods that have been developed in the human and animal models to differentiate between parent and child effects has been to study multiple offspring in the family. By holding the parent steady, and studying different offspring, we can examine the similarities and differences in how parents parent multiple offspring. Studies have distinguished between family average parenting, child-specific parenting and family-wide dispersion (the within family standard deviation). These different aspects of parenting have been differentially linked to offspring behavioral phenotypes. Crown Copyright © 2015. Published by Elsevier Inc. All rights reserved.

Transformational Leadership, Transactional Contingent Reward, and Organizational Identification: The Mediating Effect of Perceived Innovation and Goal Culture Orientations.

Science.gov (United States)

Xenikou, Athena

2017-01-01

Purpose: The aim of this research was to investigate the effect of transformational leadership and transactional contingent reward as complementary, but distinct, forms of leadership on facets of organizational identification via the perception of innovation and goal organizational values. Design/Methodology/Approach: Three studies were carried out implementing either a measurement of mediation or experimental-causal-chain design to test for the hypothesized effects. Findings: The measurement of mediation study showed that transformational leadership had a positive direct and indirect effect, via innovation value orientation, on cognitive identification, whereas transactional contingent reward was more strongly related to affective, rather than cognitive, identification, and goal orientation was a mediator of their link. The findings of the two experimental-causal-chain studies further supported the hypothesized effects. Transformational leadership was found to lead subordinates to perceive the culture as more innovative compared to transactional contingent reward, whereas transactional contingent reward led employees to perceive the culture as more goal, than innovation, oriented. Finally, innovation, compared to goal, value orientation increased cognitive identification, while goal orientation facilitated affective, rather than cognitive, identification. Implications: The practical implications involve the development of strategies organizations can apply, such as leadership training programs, to strengthen their ties with their employees, which, in turn, may have a positive impact on in-role, as well as extra-role, behaviors. Originality/Value: The originality of this research concerns the identification of distinct mechanisms explaining the effect of transformational leadership and transactional contingent reward on cognitive and affective identification applying an organizational culture perspective and a combination of measurement and causal mediation designs.

Transaction costs and community-based natural resource management in Nepal.

Science.gov (United States)

Adhikari, Bhim; Lovett, Jon C

2006-01-01

Transaction costs in community-based resource management are incurred by households attempting to enforce property right rules over common resources similar to those inherent in private property rights. Despite their importance, transaction costs of community-based management of common pool resources (CPRs) are often not incorporated into the economic analysis of participatory resource management. This paper examines the transaction costs incurred by forest users in community forestry (CF) based on a survey of 309 households belonging to eight different forest user groups (FUGs) in the mid hills of Nepal. The analysis reveals that the average 'poor' household incurred Nepalese rupees (NRS) 1265 in transaction costs annually, while wealthier 'rich' households incurred an average of NRS 2312 per year. Although richer households bear higher proportions of such costs, transaction costs for CF management as a percentage of resource appropriation costs are higher for poorer households (26%) than those of middle-wealth (24%) or rich households (14%). There are also village differences in the level of transaction costs. The results show that transaction costs are a major component of resource management costs and vary according to socio-economic status of resource users and characteristics of the community.

Customer-Specific Transaction Risk Management in E-Commerce

Science.gov (United States)

Ruch, Markus; Sackmann, Stefan

Increasing potential for turnover in e-commerce is inextricably linked with an increase in risk. Online retailers (e-tailers), aiming for a company-wide value orientation should manage this risk. However, current approaches to risk management either use average retail prices elevated by an overall risk premium or restrict the payment methods offered to customers. Thus, they neglect customer-specific value and risk attributes and leave turnover potentials unconsidered. To close this gap, an innovative valuation model is proposed in this contribution that integrates customer-specific risk and potential turnover. The approach presented evaluates different payment methods using their risk-turnover characteristic, provides a risk-adjusted decision basis for selecting payment methods and allows e-tailers to derive automated risk management decisions per customer and transaction without reducing turnover potential.

Makino, Tomohiro; Lim, Yeongjoo; Kodama, Kota

2018-03-21

Although external collaboration capability influences the development of personalized medicine, key transactions in the pharmaceutical industry have not been addressed. To explore specific trends in interorganizational transactions and key players, we longitudinally surveyed strategic transactions, comparing them with other advanced medical developments, such as antibody therapy, as controls. We found that the financing deals of start-ups have surged over the past decade, accelerating intellectual property (IP) creation. Our correlation and regression analyses identified determinants of financing deals among alliance deals, acquisition deals, patents, research and development (R&D) licenses, market licenses, and scientific papers. They showed that patents positively correlated with transactions, and that the number of R&D licenses significantly predicted financing deals. This indicates, for the first time, that start-ups and investors lead progress in personalized medicine. Copyright © 2018 Elsevier Ltd. All rights reserved.

Structure and Anonymity of the Bitcoin Transaction Graph

Directory of Open Access Journals (Sweden)

Kay Hamacher

2013-05-01

Full Text Available The Bitcoin network of decentralized payment transactions has attracted a lot of attention from both Internet users and researchers in recent years. Bitcoin utilizes a peer-to-peer network to issue anonymous payment transactions between different users. In the currently used Bitcoin clients, the full transaction history is available at each node of the network to prevent double spending without the need for a central authority, forming a valuable source for empirical research on network structure, network dynamics, and the implied anonymity challenges, as well as guidance on the future evolution of complex payment systems. We found dynamical effects of which some increase anonymity while others decrease it. Most importantly, several parameters of the Bitcoin transaction graph seem to have become stationary over the last 12–18 months. We discuss the implications.

Commodity movement tracking (CMT) : bridging operations and commercial transactions

International Nuclear Information System (INIS)

Lewyta, M.

2004-01-01

Enbridge Pipelines Inc. (EPI) operates a network of interconnected pipelines that facilitate the transport of liquid fuels across North America, with operations centralized in Edmonton, Alberta. This paper addressed the issue of accurately tracking the location of commodities transported on EPI pipelines for billing and payment purposes. The role of integrated information systems in meeting the need for high quality information by customers and by EPI was also addressed. The paper presented the Commodity Movement Tracking (CMT) system that is central to achieving the desired accuracy of commercial and financial transactions. CMT tracks inventories and links products to commercial transactions across the pipeline. Batches are tracked from initial receipt to final delivery, incorporating CMT's operational checks and balances, reconciliation steps, process monitoring, and supervisory control and data acquisition (SCADA) systems data that contribute to inputs equaling outputs. Daily schedules are recorded into the CMT system as events, based on volumetric information derived from the SCADA system. Receipt and delivery events will be electronically recorded into CMT from field flow computers in the near future. CMT modeling considers changes within the line configuration, static pipe diameter changes, as well as packing and draining of the line fill resulting from pressure changes. This paper described the major functional activities of the overall business process, such as nominations, scheduling, commodity movement tracking, leak detection, electronic ticketing, SCADA, and oil accounting. 10 figs.

Transaction costs, externalities and information technology in health care.

Science.gov (United States)

Ferguson, B; Keen, J

1996-01-01

This paper discusses some of the economic issues which underpin the rationale for investment in information and communications technologies (ICTs). Information imperfections lead to significant transaction costs (search, negotiating and monitoring) which in turn confer a negative externality on parties involved in exchange. This divergence in private and social costs leads to a degree of resource misallocation (efficiency loss) which, uncorrected, results in a sub-optimal outcome. Traditional solutions to this problem are to rely upon direct government action to reduce the costs of transacting between market agents, or to employ tax/subsidy measures and other legislative action to achieve the desired market outcome. Three key policy questions are raised in the context of the NHS purchaser/provider relationship. Firstly, what is the optimum level of transaction costs; secondly, can ICTs assist in lowering the level of transaction costs to the optimum level; thirdly, who should bear the investment cost in reducing the level of transaction costs? The issue of property rights in different information systems is discussed and raises interesting policy questions about how much investment should be undertaken centrally rather than devolved to a more local level. In some ways this economic framework offers a post hoc justification of why different ICT systems have been introduced at various levels of the NHS. Essentially this reduces to the problem of externalities: providing good information confers a positive externality: not providing relevant, timely and accurate information confers a negative externality, by increasing further the level of transaction costs. The crucial role which ICT systems can play lies in attempting to reduce the level of transaction costs and driving the market towards what Dahlman has described as the transaction-cost-constrained equilibrium.

Environmental site assessments should include radon gas testing

International Nuclear Information System (INIS)

Nardi, M.A.

1991-01-01

There are two emerging influences that will require radon gas testing as part of many property transfers and most site assessments. These requirements come from lending regulators and state legislatures. Fannie Mae and others have developed environmental investigation guidelines for the purchase of environmentally contaminated real estate. These guidelines include radon gas testing for many properties. Several states have enacted laws that require environmental disclosure forms be prepared to ensure that the parties involved in certain real estate transactions are aware of the environmental liabilities that may come with the transfer of property. Indiana has recently enacted legislation that would require the disclosure of the presence of radon gas on many commercial real estate transactions. With more lenders and state governments likely to follow this trend, radon gas testing should be performed during all property transfers and site assessment to protect the parties involved from any legal liabilities

Transaction based approach

Science.gov (United States)

Hunka, Frantisek; Matula, Jiri

2017-07-01

Transaction based approach is utilized in some methodologies in business process modeling. Essential parts of these transactions are human beings. The notion of agent or actor role is usually used for them. The paper on a particular example describes possibilities of Design Engineering Methodology for Organizations (DEMO) and Resource-Event-Agent (REA) methodology. Whereas the DEMO methodology can be regarded as a generic methodology having its foundation in the theory of Enterprise Ontology the REA methodology is regarded as the domain specific methodology and has its origin in accountancy systems. The results of these approaches is that the DEMO methodology captures everything that happens in the reality with a good empirical evidence whereas the REA methodology captures only changes connected with economic events. Economic events represent either change of the property rights to economic resource or consumption or production of economic resources. This results from the essence of economic events and their connection to economic resources.

Transactive Control of Commercial Buildings for Demand Response

Energy Technology Data Exchange (ETDEWEB)

Hao, He; Corbin, Charles D.; Kalsi, Karanjit; Pratt, Robert G.

2017-01-01

Transactive control is a type of distributed control strategy that uses market mechanism to engage self-interested responsive loads to achieve power balance in the electrical power grid. In this paper, we propose a transactive control approach of commercial building Heating, Ventilation, and Air- Conditioning (HVAC) systems for demand response. We first describe the system models, and identify their model parameters using data collected from Systems Engineering Building (SEB) located on our Pacific Northwest National Laboratory (PNNL) campus. We next present a transactive control market structure for commercial building HVAC system, and describe its agent bidding and market clearing strategies. Several case studies are performed in a simulation environment using Building Control Virtual Test Bed (BCVTB) and calibrated SEB EnergyPlus model. We show that the proposed transactive control approach is very effective at peak clipping, load shifting, and strategic conservation for commercial building HVAC systems.

Directory of Open Access Journals (Sweden)

V. VALENTINOV

2008-12-01

Full Text Available In many parts of the world, rural development is supported by third sector organizations, such as nongovernmental organizations, farmer associations, and cooperatives. This essay develops a transaction cost explanation of these organizations’ role in rural areas. Since the traditional transaction cost theory is concerned with the choice of governance mechanisms within the for-profit sector, this essay adopts an alternative conceptualization of the notion of transaction cost by building on the theory of the division of labor. This theory regards transaction cost as a constraint on the division of labor causing the replacement of exchange with self-sufficiency. The proposed transaction cost explanation of rural third sector organizations consists of two arguments: 1 third sector organizations embody partial reliance on self-sufficiency; and 2 rural areas exhibit rurality-specific transaction cost acting as a constraint on the division of labor and thus creating a niche for third sector organizations. The essay concludes with suggesting a research program on developing an economic theory of the rural third sector.;

Can rewards for environmental services benefit the poor? Lessons from Asia

Directory of Open Access Journals (Sweden)

Beria Leimona

2009-04-01

Full Text Available Pro-poor rewards for environmental services (RES link global priorities on poverty reduction and environmental sustainability. Emerging approaches to payment for environmental services vary in mechanism and form of payment. Rural poverty is multidimensional and the poverty syndromes vary with the intensity of landscape use and management, with the solution to lack of access to markets, education and healthcare associated with loss of natural capital. RES mechanisms have to balance effectiveness and efficiency with fairness and pro-poor characteristics, with transaction costs as obstacles to both. The economic perspective on financial transfers needs to be balanced with the social and environmental paradigms of fairness. Our first hypothesis is that only under specific circumstances, actual cash incentive to individual participants of RES will contribute substantially to poverty alleviation of ES providers. The second hypothesis is that non-financial incentive to ES providers will contribute to reducing poverty by linking the community (participants and non-participants to access to capital types (human, social/political, natural, infrastructure and financial, such as microcredit. Review of key ratios of relative number and wealth of service providers and beneficiaries supports the first hypothesis and rejects the notion of widespread potential for reducing upstream rural poverty through individual cash payments. Results of community focus group discussions support the second hypothesis through context-specific preferences for the mechanisms by which RES can trigger conditions for sustainable development.

Medium-term load forecasting and wholesale transaction profitability

International Nuclear Information System (INIS)

Selker, F.K.; Wroblewski, W.R.

1996-01-01

The volume of wholesale transactions quoted at firm prices is increasing. The cost, and thus profitability, of serving these contracts strongly depends upon native load during the time of delivery. However, transactions extend beyond load forecasts based on weather information, and long-term resource planning forecasts of load peaks and energy provide inadequate detail. To address this need, Decision Focus Inc. (DFI) and Commonwealth Edison (ComEd) developed a probabilistic, medium-term load forecasting capability. In this paper the authors use a hypothetical utility to explore the impact of uncertain medium-term loads on transaction profitability

Transactional sex is a structural driver of HIV for women and girls in sub-Saharan Africa. In transactional relationships, sexual and economic obligations intertwine and may have positive and negative effects on women's financial standing and social status. We conducted a clinic-based survey with pregnant women in Swaziland using a locally validated transactional sex scale to measure the association between subjective social status, transactional sex, and HIV status, and to assess whether this association differed according to a woman's agency within her relationship. We recruited a convenience sample of 406 pregnant women at one rural and one urban public antenatal clinic in Swaziland and administered a behavioural survey that was linked to participant HIV status using clinic records. We then conducted a multigroup path analysis to test three hypotheses: (1) that more engagement in transactional sex is associated with decreased condom use and increased subjective social status; (2) that subjective social status mediates the relationship between transactional sex and HIV status; and (3) that these relationships are different across groups according to whether or not a woman reported any indicator of constrained agency within her relationship. The amount and value of material goods received from a sexual partner was significantly and positively associated with higher subjective social status among all participants. As the amount of material goods received from a partner increased, women who reported no indicators of constrained agency were less likely to use condoms. Conversely, there was no relationship between transactional sex and condom use among women who reported any indicator of constrained relationship agency. Among women who reported any indicator of constrained agency, HIV was significantly associated with lower subjective social status. Relationship agency likely plays a key role in determining which mechanisms create HIV risk for women in transactional

Transformational Leadership, Transactional Contingent Reward, and Organizational Identification: The Mediating Effect of Perceived Innovation and Goal Culture Orientations

Science.gov (United States)

Xenikou, Athena

2017-01-01

Purpose: The aim of this research was to investigate the effect of transformational leadership and transactional contingent reward as complementary, but distinct, forms of leadership on facets of organizational identification via the perception of innovation and goal organizational values. Design/Methodology/Approach: Three studies were carried out implementing either a measurement of mediation or experimental-causal-chain design to test for the hypothesized effects. Findings: The measurement of mediation study showed that transformational leadership had a positive direct and indirect effect, via innovation value orientation, on cognitive identification, whereas transactional contingent reward was more strongly related to affective, rather than cognitive, identification, and goal orientation was a mediator of their link. The findings of the two experimental-causal-chain studies further supported the hypothesized effects. Transformational leadership was found to lead subordinates to perceive the culture as more innovative compared to transactional contingent reward, whereas transactional contingent reward led employees to perceive the culture as more goal, than innovation, oriented. Finally, innovation, compared to goal, value orientation increased cognitive identification, while goal orientation facilitated affective, rather than cognitive, identification. Implications: The practical implications involve the development of strategies organizations can apply, such as leadership training programs, to strengthen their ties with their employees, which, in turn, may have a positive impact on in-role, as well as extra-role, behaviors. Originality/Value: The originality of this research concerns the identification of distinct mechanisms explaining the effect of transformational leadership and transactional contingent reward on cognitive and affective identification applying an organizational culture perspective and a combination of measurement and causal mediation designs

Allocation and management issues in multiple-transaction open access transmission networks

Science.gov (United States)

Tao, Shu

This thesis focuses on some key issues related to allocation and management by the independent grid operator (IGO) of unbundled services in multiple-transaction open access transmission networks. The three unbundled services addressed in the thesis are transmission real power losses, reactive power support requirements from generation sources, and transmission congestion management. We develop the general framework that explicitly represents multiple transactions undertaken simultaneously in the transmission grid. This framework serves as the basis for formulating various problems treated in the thesis. We use this comprehensive framework to develop a physical-flow-based mechanism to allocate the total transmission losses to each transaction using the system. An important property of the allocation scheme is its capability to effectively deal with counter flows that result in the presence of specific transactions. Using the loss allocation results as the basis, we construct the equivalent loss compensation concept and apply it to develop flexible and effective procedures for compensating losses in multiple-transaction networks. We present a new physical-flow-based mechanism for allocating the reactive power support requirements provided by generators in multiple-transaction networks. The allocatable reactive support requirements are formulated as the sum of two specific components---the voltage magnitude variation component and the voltage angle variation component. The formulation utilizes the multiple-transaction framework and makes use of certain simplifying approximations. The formulation leads to a natural allocation as a function of the amount of each transaction. The physical interpretation of each allocation as a sensitivity of the reactive output of a generator is discussed. We propose a congestion management allocation scheme for multiple-transaction networks. The proposed scheme determines the allocation of congestion among the transactions on a physical

Marketable pollution permits with uncertainty and transaction costs

International Nuclear Information System (INIS)

Montero, Juan-Pablo

1998-01-01

Increasing interest in the use of marketable permits for pollution control has become evident in recent years. Concern regarding their performance still remains because empirical evidence has shown transaction costs and uncertainty to be significant in past and existing marketable permits programs. In this paper we develop theoretical and numerical models that include transaction costs and uncertainty (in trade approval) to show their effects on market performance (i.e., equilibrium price of permits and trading volume) and aggregate control costs. We also show that in the presence of transaction costs and uncertainty the initial allocation of permits may not be neutral in terms of efficiency. Furthermore, using a numerical model for a hypothetical NO x trading program in which participants have discrete control technology choices, we find that aggregate control costs and the equilibrium price of permits are sensitive to the initial allocation of permits, even for constant marginal transaction costs and certainty

Proving Opacity of Transactional Memory with Early Release

Directory of Open Access Journals (Sweden)

Siek Konrad

2015-12-01

Full Text Available Transactional Memory (TM is an alternative way of synchronizing concurrent accesses to shared memory by adopting the abstraction of transactions in place of low-level mechanisms like locks and barriers. TMs usually apply optimistic concurrency control to provide a universal and easy-to-use method of maintaining correctness. However, this approach performs a high number of aborts in high contention workloads, which can adversely affect performance. Optimistic TMs can cause problems when transactions contain irrevocable operations. Hence, pessimistic TMs were proposed to solve some of these problems. However, an important way of achieving efficiency in pessimistic TMs is to use early release. On the other hand, early release is seemingly at odds with opacity, the gold standard of TM safety properties, which does not allow transactions to make their state visible until they commit. In this paper we propose a proof technique that makes it possible to demonstrate that a TM with early release can be opaque as long as it prevents inconsistent views.

Transactional Infrastructure of the Economy: the Evolution of Concepts and Synthesis of Definitions

Full Text Available The overview of evolution of market infrastructure concepts is provided, the first concepts of institutional infrastructure are revealed in the paper. Evolutionarily developed narrowing of essence of infrastructure in connection with the priority analysis of its physical (material and technological components is proved. It ignores the fact that transactional resources, being drivers (driving forces of economic systems evolution, in turn evolve, becoming harder and harder, combining increase in efficiency of the elements and strengthening of heterogeneity and discrepancy of their structure. Transactional evolution of economy in general and evolution of separate transactional resources of production are the perspective directions of the special analysis. Transactional infrastructure is considered as the integrated complex of institutional, organizational (relational and information infrastructures. The problems of the first concepts of transactional infrastructure connected with difficulties of differentiation of its subsystems always operating jointly are revealed. Prospect of transition from the isolated analysis of separate resources of transactional type (institutes, organizations, information, social capital, trust, etc. to studying corresponding specific software infrastructures and to the system analysis of integrated transactional infrastructure of economy are argued. The transactional sector (as set of the specialized industries and the appropriate collective and individual subjects providing with resources market transaction is offered to be considered as transactional structure of economy. Transactional infrastructure is treated as critically significant factor of economic evolution which in the conditions of post-industrial type of economy gradually purchases transactional nature.

This study aimed to estimate the prevalence and risk factors for transactional sex among NIDUs in the Southwest region of Goiás State, Central Brazil. The prevalence of self-reported transactional sex was 22.8%. Prevalence in women and men was 52.7% and 16.8%, respectively, a significant difference (p<0.001. Crack use and history of sexually transmitted infections (STI were risk factors for transactional sex in men. Homelessness, crack use, sex under the influence of drugs, and history of sexual violence were risk factors for transactional sex in women. A high prevalence of transactional sex was observed among NIDUs. This risk behavior may contribute to the high rates of HIV among this population and their social networks and in the general population.

Full Text Available The paper presents the econometric procedures of identifying specific transactions, in which atypical conditions or attributes may occur. These procedures are based on studentized and predictive residuals of the accordingly specified econometric models. The dependent variable is a unit transactional price, and explanatory variables are both the real properties’ attributes and accordingly defined artificial binary variables. The utility of the proposed method has been verified by means of a real market data base. The proposed procedures can be helpful during the property valuation process, making it possible to reject real properties that are specific (both from the point of view of the transaction conditions and the properties’ attributes and, consequently, to select an appropriate set of similar attributes that are essential for the valuation process.

How vulnerable is the emissions market to transaction costs?: An ABMS Approach

International Nuclear Information System (INIS)

Lee, Kangil; Han, Taek-Whan

2016-01-01

The impact of transaction costs on the early emissions trading market is examined by applying an agent-based model and simulation (ABMS) approach. For a realistic model set up, bounded rationality, stochastic characteristics, and learning-by-doing are considered in our search processes. Marginal abatement cost parameters are obtained from Yoo et al. (2010), which is an experimental study on the emissions trading in the Korean power sector. Sensitivity analyses are performed on market performance indices with regard to transaction cost parameters, which represent scales and the learning elasticities of transaction costs. A total of 960 simulations were run in this sensitivity analysis. Sensitivity analysis results consistently show that higher transaction costs worsen market performance. The most remarkable finding in these results is that welfare performance of all the transactions decreases by up to 50% as the scale parameters of transaction costs increase, implying that welfare gain from introducing emissions trading disappears significantly. However, with learning curve effect, welfare performance could be regained by up to 26%. In sum, although transaction costs significantly encroach upon trade gains at the early stage, based on our simulation results, the welfare loss by way of transaction costs is lessened as the knowledge of market participants progresses. - Highlights: • Impact of transaction costs on small and early, primitive emissions trading market • Bounded Rationality (BR) and Zero Intelligence Plus (ZIP) agents concept • Marginal Abatement Cost (MAC) parameters delineate Korean power companies • With transaction costs, welfare gain from trade found to be shrunken • As learning proceeds, welfare loss is reduced

Subcommunities and Their Mutual Relationships in a Transaction Network

Science.gov (United States)

Iino, T.; Iyetomi, H.

We investigate a Japanese transaction network consisting ofabout 800 thousand firms (nodes) and four million business relations (links) with focus on its modular structure. Communities detected by maximizing modularity often are dominated by firms with common features or behaviors in the network, such as characterized by regions or industry sectors. However, it is well known that the modularity optimization approach has a resolution limit problem, that is, it fails in identifying fine communities buried in large communities. To unfold such hidden structures, we apply the community detection to each of subnetworks formed by isolating those communities from the whole body. Subcommunities thus identified are composed of firms with finer regions, more specified sectors or business affiliations. Also we introduce a new idea of reduced modularity matrix to measure the strength of relations between (sub)communities.

A transactional framework for pediatric rehabilitation: shifting the focus to situated contexts, transactional processes, and adaptive developmental outcomes.

Science.gov (United States)

King, Gillian; Imms, Christine; Stewart, Debra; Freeman, Matt; Nguyen, Tram

2018-07-01

A paradigm shift is taking place in pediatric rehabilitation research, practice, and policy - a shift towards the real-life contexts of clients rather than requiring clients to navigate the world of pediatric rehabilitation. This article proposes a conceptual framework to bring about a broader awareness of clients' lives and transactional processes of change over the life course. The framework draws attention to transactional processes by which individuals, situated in life contexts, change and adapt over the life course and, in turn, influence their contextual settings and broader environments. This framework is based on (a) basic tenets derived from foundational theories taking a life course perspective to change, and (b) transactional processes identified from relevant pediatric rehabilitation models that bring these foundational theories into the pediatric rehabilitation sphere. The framework identifies three types of transactional processes relevant to pediatric rehabilitation: facilitative, resiliency, and socialization processes. These processes describe how contexts and people mutually influence each other via opportunities and situated experiences, thus facilitating capacity, adaptation to adversity, and socialization to new roles and life transitions. The utility of the framework is considered for research, practice, service organizations, and policy. Implications for Rehabilitation The framework supports practitioners going beyond person and environment as separate entities, to provide services to the "situated person" in real-life contexts The framework shifts the focus from "body structures/functions" and "person in activity" to "person in changing and challenging life contexts" Working from a transactional perspective, practitioner-client conversations will change; practitioners will view client situations through a lens of opportunities and experiences, assess client experiences in real-life contexts, and strive to create context-based therapy

Autoimmunity, environmental exposure and vaccination: is there a link?

International Nuclear Information System (INIS)

Ravel, G.; Christ, M.; Horand, F.; Descotes, J.

2004-01-01

Although the wide clinical experience shows that vaccines are generally safe, concern has been expressed for a causal link between vaccines and autoimmune diseases. Even though the mechanisms of autoimmunity are ill-elucidated, the role of pre-existing risk factors including genetic predisposition and environmental factors is largely accepted. The present study was undertaken to test the hypothesis that vaccines can promote autoimmunity in genetically-prone individuals when simultaneously exposed to a chemical known to induce autoimmune reactions. Female lupus-prone (NZBxNZW) F 1 mice were given 1 μg or 10 μg of a hepatitis B vaccine at 2-week intervals in conjunction with 40 μg of mercuric chloride three times per week for 6 weeks. A marked increase in serum IgG levels and a slight increase in anti-nuclear autoantibody (ANA) levels were seen in the mice given 10 μg of the vaccine plus mercuric chloride. No straightforward conclusion can be drawn from these results because of the extreme experimental conditions of this study. Nevertheless, the results tend to support the hypothesis that vaccination could enhance the risk of autoimmunity in genetically susceptible individuals when exposed to certain environmental chemicals

Building learning communities to engage the public in identifying and solving local and regional environmental problems is the vision of the newly created Northern Great Plains Center for People and the Environment at the University of North Dakota. The Center serves as an Environmental Information Bridge between science and society for citizens of the region, providing information, data, and value-added remote sensing products to precision agriculture, sustainable forestry, Native American land managers, and K-lifetime educators. Guided by the needs of end users, the new Center is a prototype for a national infrastructure that meets ESE's objective to "expand and accelerate the realization of economic and societal benefits from Earth science, information, and technology". The scientific community has been good at converting raw data into useful information. However, a serious communications gap exists between the communities of scientists and non-scientists. The new Center bridges this gap, creating a many-to-many exchange of information among those who learn first about the environment and those who will put those lessons to work for their economic welfare, the betterment of the quality of their lives, and the benefit of their descendants. A major outreach component of the Center, written and produced at UND, is Our Changing Planet, a public television series aimed at increasing viewers' awareness of environmental and climate change issues. Now carried by approximately 30 public television stations the series is distributed nationwide by the National Education Television Association. The Center has also recently established a partnership with StormCenter.com, LLC, a multimedia company and fellow partner in NASA's Federation of Earth Science Information Partners that uses leading-edge technology to deliver information about the environment to regional television stations.

Even though there is a growing interest in related party transactions, there is little academic literature to understand the nature of related party transactions and their economic consequences. Our study was conducted on a sample of 40 companies listed companies on Bucharest Stock Exchange activating in manuafacuring sector. Our objective was to analyse the way the companies follow the requirements of transparency of related party transaction. Based on our observations on companies� financial reports and companies web-sites, the level of transparency between these companies was reflected by an index estimated from producers� scores on Likert-type scales (one to five that showed to what extent they disclose or not disclose information such as relationship between parents and subsidiaries, key management personnel compensation, the value of transactions with related parties or separate disclosure for the group entities.

Environmental stress, ageing and glial cell senescence: a novel mechanistic link to Parkinson's disease?

Exposure to environmental toxins is associated with a variety of age-related diseases including cancer and neurodegeneration. For example, in Parkinson's disease (PD), chronic environmental exposure to certain toxins has been linked to the age-related development of neuropathology. Neuronal damage is believed to involve the induction of neuroinflammatory events as a consequence of glial cell activation. Cellular senescence is a potent anti-cancer mechanism that occurs in a number of proliferative cell types and causes the arrest of proliferation of cells at risk of malignant transformation following exposure to potentially oncogenic stimuli. With age, senescent cells accumulate and express a senescence-associated secretory phenotype (SASP; that is the robust secretion of many inflammatory cytokines, growth factors and proteases). Whereas cell senescence in peripheral tissues has been causally linked to a number of age-related pathologies, little is known about the induction of cellular senescence and the SASP in the brain. On the basis of recently reported findings, we propose that environmental stressors associated with PD may act in part by eliciting senescence and the SASP within non neuronal glial cells in the ageing brain, thus contributing to the characteristic decline in neuronal integrity that occurs in this disorder. © 2013 The Association for the Publication of the Journal of Internal Medicine.

A TRANSACTION COST ANALYSIS OF MICROPAYMENTS IN MOBILE COMMERCE

Directory of Open Access Journals (Sweden)

Daniel Gille

2012-07-01

Full Text Available Personalised, location-related and differentiated services in the mobile digitaleconomy create a demand for suitable pricing models. In the case of disaggregated“microservices” (e.g., small digitalized information or service units, as well as for theacquisition of low-value physical goods, the deployment of micropayments seemsappropriate.This paper analyzes the economic efficiency of marginal transaction amounts in the mcommercearea by applying the theoretical approach of transaction cost economics. Forthis purpose, a separation of technical and cognitive transaction costs is applied. Theinfluence of selected determinants such as specifity, uncertainty and bounded rationality ontransaction costs in mobile commerce micropayments is analyzed. The result is a morelikely application of micropayments for physical goods such as beverages or parking ticketsthan for digital goods and services, given the theoretical assumptions of the model. Inaddition, indicators for a significant above-zero lower limit of transaction amounts inmobile commerce are presented.

Measuring the influence of networks on transaction costs using a non-parametric regression technique

DEFF Research Database (Denmark)

Henningsen, Géraldine; Henningsen, Arne; Henning, Christian H.C.A.

All business transactions as well as achieving innovations take up resources, subsumed under the concept of transaction costs. One of the major factors in transaction costs theory is information. Firm networks can catalyse the interpersonal information exchange and hence, increase the access to non......-public information so that transaction costs are reduced. Many resources that are sacrificed for transaction costs are inputs that also enter the technical production process. As most production data do not distinguish between these two usages of inputs, high transaction costs result in reduced observed productivity...

Modeling an Application's Theoretical Minimum and Average Transactional Response Times

Energy Technology Data Exchange (ETDEWEB)

Paiz, Mary Rose [Sandia National Lab. (SNL-NM), Albuquerque, NM (United States)

2015-04-01

The theoretical minimum transactional response time of an application serves as a ba- sis for the expected response time. The lower threshold for the minimum response time represents the minimum amount of time that the application should take to complete a transaction. Knowing the lower threshold is beneficial in detecting anomalies that are re- sults of unsuccessful transactions. On the converse, when an application's response time falls above an upper threshold, there is likely an anomaly in the application that is causing unusual performance issues in the transaction. This report explains how the non-stationary Generalized Extreme Value distribution is used to estimate the lower threshold of an ap- plication's daily minimum transactional response time. It also explains how the seasonal Autoregressive Integrated Moving Average time series model is used to estimate the upper threshold for an application's average transactional response time.

The consequences of hospital autonomization in Colombia: a transaction cost economics analysis.

Science.gov (United States)

Castano, Ramon; Mills, Anne

2013-03-01

Granting autonomy to public hospitals in developing countries has been common over recent decades, and implies a shift from hierarchical to contract-based relationships with health authorities. Theory on transactions costs in contractual relationships suggests they stem from relationship-specific investments and contract incompleteness. Transaction cost economics argues that the parties involved in exchanges seek to reduce transaction costs. The objective of this research was to analyse the relationships observed between purchasers and the 22 public hospitals of the city of Bogota, Colombia, in order to understand the role of relationship-specific investments and contract incompleteness as sources of transaction costs, through a largely qualitative study. We found that contract-based relationships showed relevant transaction costs associated mainly with contract incompleteness, not with relationship-specific investments. Regarding relationships between insurers and local hospitals for primary care services, compulsory contracting regulations locked-in the parties to the contracts. For high-complexity services (e.g. inpatient care), no restrictions applied and relationships suggested transaction-cost minimizing behaviour. Contract incompleteness was found to be a source of transaction costs on its own. We conclude that transaction costs seemed to play a key role in contract-based relationships, and contract incompleteness by itself appeared to be a source of transaction costs. The same findings are likely in other contexts because of difficulties in defining, observing and verifying the contracted products and the underlying information asymmetries. The role of compulsory contracting might be context-specific, although it is likely to emerge in other settings due to the safety-net role of public hospitals.

COULD SOCIOECONOMIC METABOLISM BE MOLDED BY TRANSACTION COSTS?

Directory of Open Access Journals (Sweden)

RALUCA I. IORGULESCU

2017-06-01

Full Text Available Two key issues that shape the economic development and growth of a country are the independence and effectiveness of the judicial system and the level of bureaucracy. The theory of transaction costs, developed, among others, by Douglass C. North, explores both. Increasing the independence and effectiveness of the judicial system reduces corruption and protects private property and economic freedom while reducing bureaucracy is absolutely necessary to increase a country's competitiveness by lowering the cost and increasing the speed of transactions. This paper introduces the transaction costs approach, the concept of ‘socioeconomic/societal metabolism’ and takes advantage of the Multi-Scale Integrated Analysis of Societal and Ecosystem Metabolism (MuSIASEM to examine how the ‘socioeconomic/societal metabolism’ could be impacted.

The transaction costs driving captive power generation: Evidence from India

International Nuclear Information System (INIS)

Ghosh, Ranjan; Kathuria, Vinish

2014-01-01

The 2003 Indian Electricity Act incentivizes captive power production through open access in an attempt to harness all sources of generation. Yet, we observe that only some firms self-generate while others do not. In this paper we give a transaction cost explanation for such divergent behavior. Using a primary survey of 107 firms from India, we construct a distinct variable to measure the transaction-specificity of electricity use. The ‘make or buy’ decision is then econometrically tested using probit model. Results are highly responsive to transaction-specificity and the likelihood of captive power generation is positively related to it. At the industrial level, this explains why food and chemical firms are more likely to make their own electricity. Since the burden of poor grid supply is highest on smaller sized and high transaction-specific firms, the grid access policies need to account for firm-level characteristics if government wants to incentivize captive power generation. - Highlights: • We analyze why some firms opt for captive power generation while others do not. • We examine the role of transaction costs in this decision making using probit model. • Unique data from a primary survey of manufacturing firms in Andhra Pradesh, India. • Transaction-specificity significantly determines who installs captive power plant (CPP). • Firm-level characteristics crucial in policies incentivizing captive generation

The Transactional Network Project is a multi-lab activity funded by the US Department of Energy?s Building Technologies Office. The project team included staff from Lawrence Berkeley National Laboratory, Pacific Northwest National Laboratory and Oak Ridge National Laboratory. The team designed, prototyped and tested a transactional network (TN) platform to support energy, operational and financial transactions between any networked entities (equipment, organizations, buildings, grid, etc.). PNNL was responsible for the development of the TN platform, with agents for this platform developed by each of the three labs. LBNL contributed applications to measure the whole-building electric load response to various changes in building operations, particularly energy efficiency improvements and demand response events. We also provide a demand response signaling agent and an agent for cost savings analysis. LBNL and PNNL demonstrated actual transactions between packaged rooftop units and the electric grid using the platform and selected agents. This document describes the agents and applications developed by the LBNL team, and associated tests of the applications.

Adaptive salinity management in the Murray-Darling Basin: a transaction cost study

Science.gov (United States)

Loch, A. J.

2017-12-01

Transaction costs hinder or promote effective management of common good resource intertemporal externalities. Appropriate policy choices may reduce externalities and improve social welfare, and transaction cost analysis can help to evaluate policy choices. However, without measurement of relevant transaction costs such policy evaluation remains challenging. This article uses a time series dataset of salinity management program to test theory aimed at transaction cost-based policy evaluation and adaptive resource management over a period of 30 years worth of data. We identify peaks and troughs in transaction costs over time, lag-effects in program expenditure, and calculate the decay in transaction cost impacts. We conclude that Australian salinity management programs are achieving flexible institutional outcomes and effective policy arrangements with long-term benefits. Proposed changes to the program moving forward add weight to our assertions of adaptive strategies, and illustrate the value of the novel data-driven tracnsaction cost analysis approach for other jurisdictions.

How much due diligence is enough? (in oil and gas property transactions)

International Nuclear Information System (INIS)

Edie, D.C.

1999-01-01

The issue of due diligence for oil and gas property transactions was discussed, with particular emphasis on how to find an appropriate balance between cost and protection (risk aversion) within an available time period. The paper focused primarily on oil and gas reserves transactions comprised of petroleum and natural gas rights, leases, operating and title documents, tangibles and the regulatory authorizations needed to acquire, hold and operate these assets. Various concerns related to gas processing plants and pipeline facilities were also treated. Issues of due diligence that should always be raised were emphasized. These are: (1) acceptability of the purchaser to the Alberta Energy and Utilities Board or other regulators as an operator for the purposes of transfer of well and facility licenses, (2) assessment of the purchaser's financial status for environmental liabilities relating to the assets following closing, (3) in an asset swap, property due diligence will be the same for both parties, and (4) where the assets are sold in exchange for stock, the purchaser should at least address concerns about the purchaser's liquidity, the purchaser's underlying asset value, and necessary regulatory authorizations to issue the stock. 10 refs

Transaction Costs, the Phenomenon of the Trading House and Economic Organization

Directory of Open Access Journals (Sweden)

Kiryanov Igor, V.

2015-12-01

Full Text Available The present paper contains a study of the phenomenon of company’s specific internal divisions called “trading house”. The analysis of different approaches (based on results obtained by R. Coase and O. Williamson towards the problem of impact of transaction cost on company size leads to the following conclusion: the company size mostly depends on its institutional architecture which includes specific divisions that ensure outsourcing of intergroup transaction cost. I propose to call these divisions centers of transaction cost. I suppose that the wide popularity of trading houses among companies belonging to different branches can be explained by the fact that a trading house is mostly used not as selling and purchasing division, but as a center of transaction cost that concentrates the biggest transaction cost (by its share within company’s general expenses. This reasoning leads to possibility of existence of a set of methodological principles that allow to build up an a priori model of expanding company. The process of expansion represents a series of inclusion of centers of transactions cost by the company after institutional advantages of an earlier institutional architecture disappear. This methodology allows to set up a classification between a classical company as a structure with low level of integration and frozen institutional architecture and an economic organization that represents an explicitly constructed composition including centers of transaction cost that help to extend the transformational space of an expanding company.

We study the implications of a property market transaction tax. As property buyers are obligated to pay a transaction tax (¡§stamp duty¡¨ or SD) where the rate increases with the value of the transaction, there are incentives to trade at the cutoff points of the tax schedule or just below them. Thus, both ¡§bunching in transactions¡¨ and ¡§underpricing¡¨ should be observed near those cutoffs. Furthermore, the bunching points should change with the tax schedule.

Money laundering: correlation between risk assessment and suspicious transactions

Directory of Open Access Journals (Sweden)

Sonja Cindori

2013-06-01

Full Text Available The risk assessment system was introduced in the Republic of Croatia in 2009, as a result of harmonization with international standards, especially the Directive 2005/60/EC on the prevention of the use of the financial system for the purpose of money laundering and terrorist financing. Risk assessment is an extensive concept which requires not only a legislative framework, but also the application of numerous criteria for its effective implementation in practice. Among these criteria are suspicious transactions, closely related to the assessment of the customer, transaction, product or service.The undeniable contribution of suspicious transactions to the quality of the risk assessment system will be confirmed by a statistical analysis of a number of West and East European countries. A combination of strict, but sufficiently flexible legal provisions governing the system for prevention of money laundering and terrorist financing and a statistical analysis of reported suspicious transactions will lead to conclusions that either support or represent criticism of the efficiency of application of the risk assessment system in practice.The aforementioned statistical analysis will show whether suspicious transactions are a reliable criterion for the risk assessment analysis, and whether they can be considered the only such criterion. There is a possibility that the findings of the analysis will be contradictory to those of some international studies.

Transactional Mechanism of Territorial Administration: Conceptualisation and Systematization of Elements

Directory of Open Access Journals (Sweden)

Elena Аleksandrovna Petrova

2016-12-01

Full Text Available The concept of transaction expenses developed by R. Coase allows to consider functioning of economy and its agents from the information viewpoint. This viewpoint implies that information exchange between agents and the urge to overcome information incompleteness start playing the crucial role. Transaction expenses are information exchange costs for the purpose of elimination (reduction of its incompleteness and the related uncertainty. R. Coase showed that creation and the size of firms are closely connected with the urge to minimize transaction expenses. Traditionally transaction expenses are associated with functioning of firms, however, the state actively participates in economy, for example, through formation of tax policy. Besides, financing of the public benefits takes place on the basis of collective decisions. But collective character of the decision causes interest, though smaller in comparison with the private choice, in the maximum efficiency of the decision. It is ensured by two factors: firstly, the position of an individual is not of great importance at collective decision-making; secondly, an individual is responsible for a small part of benefits and expenses which are formed in the course of decision implementation. The article deals with the concept of transaction costs, and systematically occurring types of transaction costs in the following groups: search information costы, the cost of negotiating, measuring costs, the costs of specification and protection of property rights, the costs of opportunistic behavior, the cost of “politicizing”, the costs of collective decisionmaking, influence costs. The authors propose a model of transaction mechanism of territorial administration, which includes the following elements: economic entities; a goal determined by system of indicators; methods; instruments; channels; forms of target use; landmark feedback on the system; subject to the experience stage of modernization; criteria

This paper explores the likely impact of emissions trading design on transaction costs. Transaction costs include both the costs for the private sector to comply with the scheme rules and the costs of scheme administration. In economic theory transaction costs are often assumed to be zero. But transaction costs are real costs and there is no reason for treating them differently to other costs. Thus, in setting up an emissions trading scheme, transaction costs have to be taken into account in ...

Epigenetic: a molecular link between testicular cancer and environmental exposures.

Vega, Aurelie; Baptissart, Marine; Caira, Françoise; Brugnon, Florence; Lobaccaro, Jean-Marc A; Volle, David H

2012-01-01

In the last decades, studies in rodents have highlighted links between in utero and/or neonatal exposures to molecules that alter endocrine functions and the development of genital tract abnormalities, such as cryptorchidism, hypospadias, and impaired spermatogenesis. Most of these molecules, called endocrine disrupters exert estrogenic and/or antiandrogenic activities. These data led to the hypothesis of the testicular dysgenesis syndrome which postulates that these disorders are one clinical entity and are linked by epidemiological and pathophysiological relations. Furthermore, infertility has been stated as a risk factor for testicular cancer (TC). The incidence of TC has been increasing over the past decade. Most of testicular germ cell cancers develop through a pre-invasive carcinoma in situ from fetal germ cells (primordial germ cell or gonocyte). During their development, fetal germ cells undergo epigenetic modifications. Interestingly, several lines of evidence have shown that gene regulation through epigenetic mechanisms (DNA and histone modifications) plays an important role in normal development as well as in various diseases, including TC. Here we will review chromatin modifications which can affect testicular physiology leading to the development of TC; and highlight potential molecular pathways involved in these alterations in the context of environmental exposures.

Impact of multilateral congestion management on the reliability of power transactions

International Nuclear Information System (INIS)

Rodrigues, A.B.; Da Silva, M.G.

2003-01-01

The restructuring of the electricity industry has caused an increase in the number of transactions in the energy market. These transactions are defined by market forces without considering operational constraints of the transmission system. Consequently, there are transactions that cause congestion in the transmission network. This paper has as objective to assess the impact of multilateral congestion management on the reliability of power transactions. This assessment is based on reliability indices such as expected power curtailments, curtailment probability, expected cost of congestion management and probability distributions of the total power curtailment. Tests results with IEEE RTS-1996 demonstrate that the multilateral management results in smaller curtailments and congestion costs than traditional bilateral management. (author)

Analysis of transaction costs for the supply and demand for wood fuels

Roos, A.; Bohlin, F.; Hektor, B.; Hillring, B.; Parikka, M.

2001-12-01

The objective of the project was to analyse the importance of transaction costs for the supply and demand for woodfuels in Sweden. The project covered the period of great expansion of woodfuel use in the district heating sector, from 1980 until present. It uses literature studies, case studies and surveys. New institutional theory and transaction cost theory was applied. Several transaction costs have influenced both supply from the forest owners and demand from the main users, the district heating plants. Many of these transaction costs have been reduced by the market players, through learning, technical improvements and institutional innovations. Actions to reduce transaction costs have accompanied technical improvements of handling and transport. Strategies for woodfuel procurement have also been analysed. Important conclusions of the project for a change in the energy system are presented

Realisation of functions of planning and organisation in the system of management of transaction expenses

Directory of Open Access Journals (Sweden)

Krush Peter V.

2014-01-01

Full Text Available The goal of the article lies in building a functional model of management of transaction expenses of an enterprise with specification of stages of realisation of planning functions in an organisation. In the result of the study the article marks out functions of management of transaction expenses, which ensure transformation of incoming (financial resources into outgoing ones (optimised transaction expenses. The article identifies stages of realisation of “Planning transaction expenses” and “Organisation of management of transaction expenses” functions. It characterises in detail responsibilities of enterprise subdivisions that deal with management of transaction expenses. It establishes that the original element of the planning function is the budget of transaction expenses for a planning period and organisation – job descriptions of employees with detailed description of their duties and authorities, rights and obligations. The prospect of further scientific developments is study of stages of realisation of such management functions as “Motivation of personnel on rational use of funds and management of transaction expenses”, “Control over the state of management of transaction expenses” and “Regulation of the process of management of transaction expenses” of enterprises.

A Mechanically Proved and an Incremental Development of the Session Initiation Protocol INVITE Transaction

Directory of Open Access Journals (Sweden)

Rajaa Filali

2014-01-01

Full Text Available The Session Initiation Protocol (SIP is an application layer signaling protocol used to create, manage, and terminate sessions in an IP based network. SIP is considered as a transactional protocol. There are two main SIP transactions, the INVITE transaction and the non-INVITE transaction. The SIP INVITE transaction specification is described in an informal way in Request for Comments (RFC 3261 and modified in RFC 6026. In this paper we focus on the INVITE transaction of SIP, over reliable and unreliable transport mediums, which is used to initiate a session. In order to ensure the correctness of SIP, the INVITE transaction is modeled and verified using event-B method and its Rodin platform. The Event-B refinement concept allows an incremental development by defining the studied system at different levels of abstraction, and Rodin discharges almost all proof obligations at each level. This interaction between modeling and proving reduces the complexity and helps in assuring that the INVITE transaction SIP specification is correct, unambiguous, and easy to understand.

Plural Governance: A Modified Transaction Cost Model

DEFF Research Database (Denmark)

Mols, Niels Peter; Menard, Claude

2014-01-01

Plural governance is a form of governance where a firm both makes and buys similar goods or services. Despite a widespread use of plural governance there are no transaction cost models of how plural governance affects performance. This paper reviews the literature about plural forms and proposes...... a model relating transaction cost and resource-based variables to the cost of the plural form. The model is then used to analyze when the plural form is efficient compared to alternative governance structures. We also use the model to discuss the strength of three plural form synergies....

Determinants of Transactions Costs in the Brazilian Stock Market

Directory of Open Access Journals (Sweden)

Antonio Zoratto Sanvicente

2012-06-01

Full Text Available The Lesmond (2005 method for estimating transactions costs, based on a limited-dependent variable model, is used in order to test for the significance of plausible explanations for cross sectional cost differences. Variables such as liquidity, volatility, firm size, quality of corporate governance and participation in ADR programs are considered, in addition to the possible impact of the 2008 crisis. Daily data for 1999-2009 are used, covering at least 250 securities each year. The average total transaction cost declined from 2.95% in 1999 to 1.22% in 2009. Stock volatility and quality of corporate governance appear to be the most relevant factors associated with the measure of transactions cost.

Environmental stress, ageing and glial cell senescence: a novel mechanistic link to Parkinson’s disease?

Science.gov (United States)

Chinta, Shankar J; Lieu, Christopher A; DeMaria, Marco; Laberge, Remi-Martin; Campisi, Judith; Andersen, Julie K

2013-01-01

Exposure to environmental toxins is associated with a variety of age-related diseases including cancer and neurodegeneration. For example, in Parkinson’s disease (PD), chronic environmental exposure to certain toxins has been linked to the age-related development of neuropathology. Neuronal damage is believed to involve the induction of neuroinflammatory events as a consequence of glial cell activation. Cellular senescence is a potent anti-cancer mechanism that occurs in a number of proliferative cell types and causes the arrest of proliferation of cells at risk of malignant transformation following exposure to potentially oncogenic stimuli. With age, senescent cells accumulate and express a senescence-associated secretory phenotype (SASP; i.e. the robust secretion of many inflammatory cytokines, growth factors and proteases). Whereas cell senescence in peripheral tissues has been causally linked to a number of age-related pathologies, little is known about the induction of cellular senescence and the SASP in the brain. Based on recently reported findings, we propose that environmental stressors associated with PD may act in part by eliciting senescence and the SASP within non-neuronal glial cells in the ageing brain, thus contributing to the characteristic decline in neuronal integrity that occurs in this disorder.

Transaction aware tape-infrastructure monitoring

International Nuclear Information System (INIS)

Nikolaidis, Fotios; Kruse, Daniele Francesco

2014-01-01

Administrating a large scale, multi protocol, hierarchical tape infrastructure like the CERN Advanced STORage manager (CASTOR)[2], which stores now 100 PB (with an increasing step of 25 PB per year), requires an adequate monitoring system for quick spotting of malfunctions, easier debugging and on demand report generation. The main challenges for such system are: to cope with CASTOR's log format diversity and its information scattered among several log files, the need for long term information archival, the strict reliability requirements and the group based GUI visualization. For this purpose, we have designed, developed and deployed a centralized system consisting of four independent layers: the Log Transfer layer for collecting log lines from all tape servers to a single aggregation server, the Data Mining layer for combining log data into transaction context, the Storage layer for archiving the resulting transactions and finally the Web UI layer for accessing the information. Having flexibility, extensibility and maintainability in mind, each layer is designed to work as a message broker for the next layer, providing a clean and generic interface while ensuring consistency, redundancy and ultimately fault tolerance. This system unifies information previously dispersed over several monitoring tools into a single user interface, using Splunk, which also allows us to provide information visualization based on access control lists (ACL). Since its deployment, it has been successfully used by CASTOR tape operators for quick overview of transactions, performance evaluation, malfunction detection and from managers for report generation.

2009-01-01

To address the need for a simpler parallel programming model, Transactional Memory (TM) has been developed and promises good parallel performance with easy-to-write parallel code. Unlike lock-based approaches, with TM, programmers do not need to explicitly specify and manage the synchronization among threads. However, programmers simply mark code segments as transactions, and the TM system manages the concurrency control for them. TM can be implemented either in software (STM) or hardware (HT...

Provable Fair Document Exchange Protocol with Transaction Privacy for E-Commerce

Directory of Open Access Journals (Sweden)

Ren-Junn Hwang

2015-04-01

Full Text Available Transaction privacy has attracted a lot of attention in the e-commerce. This study proposes an efficient and provable fair document exchange protocol with transaction privacy. Using the proposed protocol, any untrusted parties can fairly exchange documents without the assistance of online, trusted third parties. Moreover, a notary only notarizes each document once. The authorized document owner can exchange a notarized document with different parties repeatedly without disclosing the origin of the document or the identities of transaction participants. Security and performance analyses indicate that the proposed protocol not only provides strong fairness, non-repudiation of origin, non-repudiation of receipt, and message confidentiality, but also enhances forward secrecy, transaction privacy, and authorized exchange. The proposed protocol is more efficient than other works.

2017-09-01

This study investigated (1) reciprocal links among parental psychological control, peer rejection, and adolescent externalizing (aggressive and rule-breaking behaviour), and (2) the moderating effect of an adolescent genetic factor (biologically informed polygenic score for dopamine signalling). Three-year longitudinal data from 1,116 adolescents (51% boys; M age = 13.79) and their parents included psychological measures (adolescent-reported psychological control, peer-reported rejection, and parent-reported aggressive and rule-breaking behaviour). Cross-lagged analyses showed bidirectional effects between psychological control and both aggressive and rule-breaking behaviour and a unidirectional effect of peer rejection on both forms of problem behaviour over time. Multigroup structural equation modelling revealed genetic moderation only for rule-breaking behaviour: for adolescents with intermediate levels of dopamine signalling significant environmental effects were present, whereas adolescent effects of rule-breaking behaviour on psychological control were significant for adolescents with both intermediate and high profiles and effects on peer rejection only for adolescents with high dopamine profiles. Statement of contribution What is already known on this subject? Parental psychological control is related to adolescent externalizing problems. Experiencing peer rejection reinforces aggressive and rule-breaking behaviour. Single-gene studies show that dopaminergic genes influence externalizing problems directly or in interaction with the environment. What does this study add? Parental psychological control and adolescent aggressive and rule-breaking behaviour exacerbate one another longitudinally. Longitudinal associations between peer rejection and both subtypes of externalizing behaviour are unidirectional. With a polygenic approach, dopaminergic moderation is present for rule-breaking behaviour only. © 2017 The British Psychological Society.

Optimization-based sale transactions and hydrothermal scheduling

International Nuclear Information System (INIS)

Prasannan, B.; Luh, P.B.; Zhang, L.

1996-01-01

Selling and purchasing power are important activities for utilities because of potential savings. When a selling utility presents an offer including prices, power levels and durations, a purchasing utility selects power levels and durations within the offered range subject to relevant constraints. The decisionmaking process is complicated because transactions are coupled with system demand and reserve, therefore decisions have to be made in conjunction with the commitment and dispatching of units. Furthermore, transaction decisions have to be made in almost real time in view of the competitiveness of the power market caused by deregulation. In this paper, transactions are analyzed from a selling utility's viewpoint for a system consisting of thermal, hydro and pumped-storage units. To effectively solve the problem, linear sale revenues are approximated by nonlinear functions, and non-profitable options are identified and eliminated from consideration. The multipliers are then updated at the high level by using a modified subgradient method to obtain near optimal solutions quickly. Testing results show that the algorithm produces good sale offers efficiently

Do transactive memory and participative teamwork improve nurses' quality of work life?

Science.gov (United States)

Brunault, Paul; Fouquereau, Evelyne; Colombat, Philippe; Gillet, Nicolas; El-Hage, Wissam; Camus, Vincent; Gaillard, Philippe

2014-03-01

Improvement in nurses' quality of work life (QWL) has become a major issue in health care organizations. We hypothesized that the level of transactive memory (defined as the way groups collectively encode, store, and retrieve knowledge) and participative teamwork (an organizational model of care based on vocational training, a specific service's care project, and regular interdisciplinary staffing) positively affect nurses' QWL. This cross-sectional study enrolled 84 ward-based psychiatric nurses. We assessed transactive memory, participative teamwork, perceived organizational justice, perceived organizational support, and QWL using psychometrically reliable and valid scales. Participative teamwork and transactive memory were positively associated with nurses' QWL. Perceived organizational support and organizational justice fully mediated the relationship between participative teamwork and QWL, but not between transactive memory and QWL. Improved transactive memory could directly improve nurses' QWL. Improved participative teamwork could improve nurses' QWL through better perceived organizational support and perceived organizational justice.

Transactive memory in organizational groups: the effects of content, consensus, specialization, and accuracy on group performance.

Science.gov (United States)

Austin, John R

2003-10-01

Previous research on transactive memory has found a positive relationship between transactive memory system development and group performance in single project laboratory and ad hoc groups. Closely related research on shared mental models and expertise recognition supports these findings. In this study, the author examined the relationship between transactive memory systems and performance in mature, continuing groups. A group's transactive memory system, measured as a combination of knowledge stock, knowledge specialization, transactive memory consensus, and transactive memory accuracy, is positively related to group goal performance, external group evaluations, and internal group evaluations. The positive relationship with group performance was found to hold for both task and external relationship transactive memory systems.

Epigenetic: a molecular link between testicular cancer and environmental exposures?

Directory of Open Access Journals (Sweden)

Aurelie eVega

2012-11-01

Full Text Available In the last decades, studies in rodents have highlighted links between in utero and/or neonatal exposures to molecules that alter endocrine functions and the development of genital tract abnormalities, such as cryptorchidism, hypospadias, and impaired spermatogenesis. Most of these molecules, called endocrine disrupters (EDs exert estrogenic and/or antiandrogenic activities. These data led to the hypothesis of the Testicular Dysgenesis Syndrome which postulates that these disorders are one clinical entity and are linked by epidemiological and pathophysiological relations. Futhermore, infertility has been stated as a risk factor for testicular cancer. The incidence of testicular cancer has been increasing over the past decades. Most of testicular germ cell cancers develop through a pre-invasive carcinoma in situ (CIS from fetal germ cells (primordial germ cell or gonocyte. During their development, fetal germ cells undergo epigenetic modifications. Interestingly, several lines of evidence have shown that gene regulation through epigenetic mechanisms (DNA and histone modifications plays an important role in normal development as well as in various diseases, including testicular cancer.Here we will review chromatin modifications which can affect testicular physiology leading to the development of testicular cancer; and highlight potential molecular pathways involved in these alterations in the context of environmental exposures.

Transaction costs of unilateral CDM projects in India-results from an empirical survey

International Nuclear Information System (INIS)

Krey, Matthias

2005-01-01

Recently, transaction costs in the context of the Clean Development Mechanism (CDM) gained considerable attention as they were generally perceived to be significantly higher than for the other Kyoto Mechanisms. However, empirical evidence on the amount of transaction costs of CDM projects is very scarce. This paper presents the results from an empirical survey designed to quantify transaction costs of potential non-sink CDM projects in India. The definition of transaction costs of CDM projects was derived from recent literature and observations made in the current market for Certified Emission Reductions (CERs). During the survey, parts of transaction costs of 15 projects were quantified. An assessment of the results showed that specific transaction costs depend, to a large extent, on economies of scale in terms of total amount of CERs generated over the crediting period. Total transaction costs were quantified for seven projects. The costs range from 0.07 to 0.47 dollar/t CO 2 . As the projects have an emission reduction between 0.24 Mt CO 2 and 5.00 Mt CO 2 over the crediting period, the results support the assumption of Michaelowa et al. (Climate Policy 3 (2003) 273) that projects with emission reductions smaller than 0.20 Mt CO 2 are not economically viable at current CER prices

Li Wang

2017-09-01

Full Text Available Purpose – The division of labor of e-commerce transaction system is an important research topic. However, there is a certain disparity between the current mainstream research model and the reality, which leads to a biased result. This paper aims to find the effects of transaction efficiency on the evolution of e-commerce transaction system’s division of labor and the relationships between the results and other parameters. Design/methodology/approach – This paper puts forward a definition of transaction efficiency based on transaction services and establishes a model of middleman’s specialized production decision of transaction services on this basis. Findings – The research results show that the transaction efficiency plays an important role on the change of middlemen’s division of labor level. The degree of economic specialization, price of commodities and transaction services and other associated factors also affect middlemen’s division of labor. Originality/value – This paper is of great significance for evaluating the development level and forecast the development direction of e-commerce.

The relationship between trading volumes, number of transactions, and stock volatility in GARCH models

Takaishi, Tetsuya; Chen, Ting Ting

2016-08-01

We examine the relationship between trading volumes, number of transactions, and volatility using daily stock data of the Tokyo Stock Exchange. Following the mixture of distributions hypothesis, we use trading volumes and the number of transactions as proxy for the rate of information arrivals affecting stock volatility. The impact of trading volumes or number of transactions on volatility is measured using the generalized autoregressive conditional heteroscedasticity (GARCH) model. We find that the GARCH effects, that is, persistence of volatility, is not always removed by adding trading volumes or number of transactions, indicating that trading volumes and number of transactions do not adequately represent the rate of information arrivals.

Personality-Relationship transaction in young adulthood.

Neyer, F J; Asendorpf, J B

2001-12-01

Personality and social relationships were assessed twice across a 4-year period in a general population sample of 489 German young adults. Two kinds of personality-relationship transaction were observed. First, mean-level change in personality toward maturity (e.g., increase in Conscientiousness and decrease in Neuroticism) was moderated by the transition to partnership but was independent of other developmental transitions. Second, individual differences in personality traits predicted social relationships much better than vice versa. Specifically, once initial correlations were controlled for, Extraversion, Shyness, Neuroticism, self-esteem, and Agreeableness predicted change in various qualities of relationships (especially with friends and colleagues), whereas only quality of relationships with preschool children predicted later Extraversion and Neuroticism. Consequences for the transactional view of personality in young adulthood are discussed.

Highlights: • Identification of cis elements responsible for SamDC expression by in silico analysis. • qPCR analysis of SamDC expression to abiotic and biotic stress treatments. • Detection of SamDC regulators using identified cis-elements as probe by EMSA. • Southwestern Blot analysis to predict the size of the trans-acting factors. - Abstract: Abiotic stress affects the growth and productivity of crop plants; to cope with the adverse environmental conditions, plants have developed efficient defense machinery comprising of antioxidants like phenolics and flavonoids, and osmolytes like polyamines. SamDC is a key enzyme in the polyamine biosynthesis pathway in plants. In our present communication we have done in silico analysis of the promoter region of SamDC to look for the presence of different cis-regulatory elements contributing to its expression. Based on the presence of different cis-regulatory elements we completed comparative analysis of SamDC gene expression in rice lamina of IR-29 and Nonabokra by qPCR in response to the abiotic stress treatments of salinity, drought, cold and the biotic stress treatments of ABA and light. Additionally, to explore the role of the cis-regulatory elements in regulating the expression of SamDC gene in plants we comparatively analyzed the binding of rice nuclear proteins prepared from IR-29 and Nonabokra undergoing various stress treatments. The intensity of the complex formed was low and inducible in IR-29 in contrast to Nonabokra. Southwestern blot analysis helped in predicting the size of the trans-acting factors binding to these cis-elements. To our knowledge this is the first report on the comprehensive analysis of SamDC gene expression in rice and identification of the trans-acting factors regulating its expression.

Laiho, M.; Skourlas, C.; Dervos, D. A.

2015-02-01

DBMS products differ in the way they support even the basic SQL transaction services. In this paper, a framework of best practices in SQL transaction programming is given and discussed. The SQL developers are advised to experiment with and verify the services supported by the DBMS product used. The framework has been developed by DBTechNet, a European network of teachers, trainers and ICT professionals. A course module on SQL transactions, offered by the LLP "DBTech VET Teachers" programme, is also presented and discussed. Aims and objectives of the programme include the introduction of the topics and content of SQL transactions and concurrency control to HE/VET curricula and addressing the need for initial and continuous training on these topics to in-company trainers, VET teachers, and Higher Education students. An overview of the course module, its learning outcomes, the education and training (E&T) content, virtual database labs with hands-on self-practicing exercises, plus instructions for the teacher/trainer on the pedagogy and the usage of the course modules' content are briefly described. The main principle adopted is to "Learn by verifying in practice" and the transactions course motto is: "Zero Tolerance for Incorrect Data".

[Pay for performance explained by transaction costs theory].

Science.gov (United States)

Gorbaneff, Yuri; Cortes, Ariel; Torres, Sergio; Yepes, Francisco

2011-01-01

To evaluate the ability of transaction costs theory to explain incentives in the health care chain. We performed a case study of CPS, a health insurance company in Bogota (Colombia), which preferred not to publish its name. CPS moves in the environment of high transaction costs and uses the hybrid form of governance at the outpatient level. Incentive intensity, administrative control and the contract all agree with the theory. At the hospital level, the market is used, despite greater uncertainty. Because of the discrete form (1.0) of the incentives and the absence of administrative control, it is difficult for CPS to relate payment to hospital performance. Transaction costs theory explains the configuration of incentives. Another contribution made by this theory to the literature is the criterion to differentiate between the market and the hybrid. We propose that the market uses discrete-type (1.0) incentives, while the hybrid uses continuous, commission-like incentives. Copyright © 2011 SESPAS. Published by Elsevier Espana.

Transaction hubs: can tame energy market communications

Energy Technology Data Exchange (ETDEWEB)

Hamilos, C.

2002-07-01

The nature and function of transaction hubs is described in view of their growing usefulness as electric industry deregulation takes hold and with it the urgent requirement for trading partners to exchange information quickly and efficiently. The paper stresses the many difficulties involved in communications between trading partners since each partner operates under a different set of business rules, with the result that there are 'language differences' to overcome, not to mention the sheer volume of data that must be handled. To make it all work, companies turn increasingly to products like communication hubs. They are able to overcome the fact that different companies have different systems, different data formats and different business rules, and are able to help companies to package, transmit, receive and process information. The principal advantage of a hub is that no one has to learn anyone else's interface. Everyone can continue to use their own data format and transaction models. The hub supplies the protocols and processing rules needed to work with any of the partners connected to the hub. In order to achieve the level of efficiency and reliability required in a hub, certain design principles must be satisfied. These are : scalability, facilities for load balancing, availability of standard routine services, ability to recognize a process as consisting of various transactions, and a transaction as belonging to a specific process, ability to allow the user to configure expiration times around the business processes according to market rules, facility to easily configure validation rules, ability to handle exceptions, ability to interoperate with many middle-ware products, and to manage work flow in a manner that is transparent to operating personnel.

The canonical molecular machinery required for global mRNA translation and its control has been well defined, with distinct sets of proteins involved in the processes of translation initiation, elongation and termination. Additionally, noncanonical, trans-acting regulatory RNA-binding proteins (RBPs) are necessary to provide mRNA-specific translation, and these interact with 5' and 3' untranslated regions and coding regions of mRNA to regulate ribosome recruitment and transit. Recently it has also been demonstrated that trans-acting ribosomal proteins direct the translation of specific mRNAs. Importantly, it has been shown that subsets of RBPs often work in concert, forming distinct regulatory complexes upon different cellular perturbation, creating an RBP combinatorial code, which through the translation of specific subsets of mRNAs, dictate cell fate. With the development of new methodologies, a plethora of novel RNA binding proteins have recently been identified, although the function of many of these proteins within mRNA translation is unknown. In this review we will discuss these methodologies and their shortcomings when applied to the study of translation, which need to be addressed to enable a better understanding of trans-acting translational regulatory proteins. Moreover, we discuss the protein domains that are responsible for RNA binding as well as the RNA motifs to which they bind, and the role of trans-acting ribosomal proteins in directing the translation of specific mRNAs.

The Problematic Aspects of Accounting the Transaction Costs and Ways to Address Them

Directory of Open Access Journals (Sweden)

Khorunzhak Nadiya M.

2017-05-01

Full Text Available The article is aimed at a theoretical generalization of the nature and causes of appearance of transaction costs, development of proposals on formation of an effective model for their management, including the proposals on the basis of improved accounting for brewery enterprises. According to the carried out analysis of the authors’ positions on accounting, including the positions related to reflection of transaction costs in the accounting records, it has been concluded about expediency to account such costs by types, although only in regard to the activities, directed toward sales of production. A goal tree graph has been built to ensure the rationality of research on elaborating the classification (grouping of transaction costs and on substantiating the composition of working accounts for their accounting. In order to ensure the continuity and timeliness of including the transaction costs into the prime cost of the production sold, it has been proposed to use planning and reporting calculations. An approach has been developed to determine the planned inclusion of transaction costs in the prime cost of the production sold (exponential average. An appropriate model for recording the transaction costs has been built. Prospect for further research will be construction of the efficient policy decisions concerning the enterprise’s activities, based on the above conception of the system of management of transaction costs together with its information base.

A Novel Electricity Transaction Mode of Microgrids Based on Blockchain and Continuous Double Auction

Directory of Open Access Journals (Sweden)

Jian Wang

2017-11-01

Full Text Available The installed capacity of distributed generation (DG based on renewable energy sources has increased continuously in power systems, and its market-oriented transaction is imperative. However, traditional transaction management based on centralized organizations has many disadvantages, such as high operation cost, low transparency, and potential risk of transaction data modification. Therefore, a decentralized electricity transaction mode for microgrids is proposed in this study based on blockchain and continuous double auction (CDA mechanism. A buyer and seller initially complete the transaction matching in the CDA market. In view of the frequent price fluctuation in the CDA market, an adaptive aggressiveness strategy is used to adjust the quotation timely according to market changes. DG and consumer exchange digital certificate of power and expenditure on the blockchain system and the interests of consumers are then guaranteed by multi-signature when DG cannot generate power due to failure or other reasons. The digital certification of electricity assets is replaced by the sequence number with specific tags in the transaction script, and the size of digital certification can be adjusted according to transaction energy quantity. Finally, the feasibility of market mechanism through specific microgrid case and settlement process is also provided.

Community Theories of Change: Linking Environmental Justice to Sustainability through Stakeholder Perceptions in Milwaukee (WI, USA

Directory of Open Access Journals (Sweden)

Kaitlyn Hornik

2016-09-01

Full Text Available Environmental justice and sustainability are compatible lenses, yet action toward equity is often missing from urban sustainability initiatives. This study aims to assess the cohesion of these frameworks in practice. To do this, we parse individuals’ theories of change, or how they identify and propose to resolve environmental injustices in the pursuit of sustainability. We posit that these theories of change are comprised of three main components: (1 perceived environmental benefits and burdens; (2 the causal pathways of environmental and social injustice; and (3 visions for positive change. Drawing from 35 stakeholder interviews in Milwaukee (WI, USA we examine individual and institutional perspectives on environmental and social change and their links to the production of injustice. Our findings reveal that participants do not distinguish between environmental and social injustices. Instead, both social and environmental factors are implicated in injustice. Furthermore, we identify two mental maps for how social and economic change reproduce injustice. These findings suggest the need to reorient how urban injustice is considered and make efforts to acknowledge how a diversity of operational theories of change could either be divisive or could bring environmental justice and sustainability initiatives together.

Division of Labor, Transaction Cost, Emergence of the Firm and Firm Size

OpenAIRE

Pak-Wai Liu; Xiaokai Yang

1999-01-01

In this paper a general equilibrium model is constructed to explain the emergence of firms and change in firm size by the tradeoff between economies of specialization and transaction cost. We show that firms emerge from the development of division of labor if the transaction efficiency for labor is smaller than that for intermediate goods. Given the emergence of firms, change in the average size of firms (average employment) will depend on the change in transaction efficiency for intermediate...

Academic Activities Transaction Extraction Based on Deep Belief Network

Directory of Open Access Journals (Sweden)

Xiangqian Wang

2017-01-01

Full Text Available Extracting information about academic activity transactions from unstructured documents is a key problem in the analysis of academic behaviors of researchers. The academic activities transaction includes five elements: person, activities, objects, attributes, and time phrases. The traditional method of information extraction is to extract shallow text features and then to recognize advanced features from text with supervision. Since the information processing of different levels is completed in steps, the error generated from various steps will be accumulated and affect the accuracy of final results. However, because Deep Belief Network (DBN model has the ability to automatically unsupervise learning of the advanced features from shallow text features, the model is employed to extract the academic activities transaction. In addition, we use character-based feature to describe the raw features of named entities of academic activity, so as to improve the accuracy of named entity recognition. In this paper, the accuracy of the academic activities extraction is compared by using character-based feature vector and word-based feature vector to express the text features, respectively, and with the traditional text information extraction based on Conditional Random Fields. The results show that DBN model is more effective for the extraction of academic activities transaction information.

Piao, Chunhui; Han, Xufang; Wu, Harris

2010-08-01

We provide a formal definition of an e-commerce transaction network. Agent-based modelling is used to simulate e-commerce transaction networks. For real-world analysis, we studied the open application programming interfaces (APIs) from eBay and Taobao e-commerce websites and captured real transaction data. Pajek is used to visualise the agent relationships in the transaction network. We derived one-mode networks from the transaction network and analysed them using degree and betweenness centrality. Integrating multi-agent modelling, open APIs and social network analysis, we propose a new way to study large-scale e-commerce systems.

Walls, S.K.

1992-01-01

This paper reviews the advantages and disadvantages of using environmental compliance audits to help detect potential environmental violations and/or potential problems. The paper focuses on the legal issues inherent in this type of audit. The primary purpose of conducting such an audit is to determine the suitability of a facility or a site prior to a transaction or to determine a company's own compliance before a regulatory agency identifies it. The paper discusses how to set up a compliance audit and then reviews how various government agencies view voluntary environmental audits. These voluntary actions are perceived by most agencies as commendable and result in significant decreases in penalties and assessments

Reconsidering Money: Monetary Exchange with Additive Transaction Costs

DEFF Research Database (Denmark)

Schröder, Philipp

2001-01-01

Under the assumption of purely additive transaction costs in exchange, the literature on money has a standard example of direct exchange dominating indirect (monetary) exchange. From here it is frequently concluded that subadditive costs (e.g. search costs) must be examined in order to explain...... money. In contrast, this paper presents an additive transaction costs model in which the mere absence of double coincidences of wants suffices to motivate monetary exchange. Furthermore it is found that not all commodity moneys, that are collectively desirable, qualify for the core, but that all fiat...

Allocation of Transaction Cost to Market Participants Using an Analytical Method in Deregulated Market

Science.gov (United States)

Jeyasankari, S.; Jeslin Drusila Nesamalar, J.; Charles Raja, S.; Venkatesh, P.

2014-04-01

Transmission cost allocation is one of the major challenges in transmission open access faced by the electric power sector. The purpose of this work is to provide an analytical method for allocating transmission transaction cost in deregulated market. This research work provides a usage based transaction cost allocation method based on line-flow impact factor (LIF) which relates the power flow in each line with respect to transacted power for the given transaction. This method provides the impact of line flows without running iterative power flow solution and is well suited for real time applications. The proposed method is compared with the Newton-Raphson (NR) method of cost allocation on sample six bus and practical Indian utility 69 bus systems by considering multilateral transaction.

Development of spreadsheet-based integrated transaction processing systems and financial reporting systems is intended to optimize the capabilities of spreadsheet in accounting data processing. The purpose of this study are: 1) to describe the spreadsheet-based integrated transaction processing systems and financial reporting systems; 2) to test its technical and operational feasibility. This study type is research and development. The main steps of study are: 1) needs analysis (need assessment); 2) developing spreadsheet-based integrated transaction processing systems and financial reporting systems; and 3) testing the feasibility of spreadsheet-based integrated transaction processing systems and financial reporting systems. The technical feasibility include the ability of hardware and operating systems to respond the application of accounting, simplicity and ease of use. Operational feasibility include the ability of users using accounting applications, the ability of accounting applications to produce information, and control applications of the accounting applications. The instrument used to assess the technical and operational feasibility of the systems is the expert perception questionnaire. The instrument uses 4 Likert scale, from 1 (strongly disagree) to 4 (strongly agree). Data were analyzed using percentage analysis by comparing the number of answers within one (1) item by the number of ideal answer within one (1) item. Spreadsheet-based integrated transaction processing systems and financial reporting systems integrate sales, purchases, and cash transaction processing systems to produce financial reports (statement of profit or loss and other comprehensive income, statement of changes in equity, statement of financial position, and statement of cash flows) and other reports. Spreadsheet-based integrated transaction processing systems and financial reporting systems is feasible from the technical aspects (87.50%) and operational aspects (84.17%).

How to increase the benefits of cooperation: Effects of training in transactive communication on cooperative learning.

Science.gov (United States)

Jurkowski, Susanne; Hänze, Martin

2015-09-01

Transactive communication means referring to and building on a learning partner's idea, by, for example, extending the partner's idea or interlinking the partner's idea with an idea of one's own. This transforms the partner's idea into a more elaborate one. Previous research found a positive relationship between students' transactive communication and their learning results when working in small groups. To increase the benefits of cooperation, we developed and tested a module for training students in transactive communication. We assumed that this training would enhance students' transactive communication and also increase their knowledge acquisition during cooperative learning. Further, we distinguished between an actor's transactive communication and a learning partner's transactive communication and expected both to be positively associated with an actor's knowledge acquisition. Participants were 80 university students. In an experiment with pre- and post-test measurements, transactive communication was measured by coding students' communication in a cooperative learning situation before training and in another cooperative learning situation after training. For the post-test cooperative learning situation, knowledge was pre-tested and post-tested. Trained students outperformed controls in transactive communication and in knowledge acquisition. Positive training effects on actors' knowledge acquisition were partially mediated by the improved actors' transactive communication. Moreover, actors' knowledge acquisition was positively influenced by learning partners' transactive communication. Results show a meaningful increase in the benefits of cooperation through the training in transactive communication. Furthermore, findings indicate that students benefit from both elaborating on their partner's ideas and having their own ideas elaborated on. © 2015 The British Psychological Society.

The long memory and the transaction cost in financial markets

Li, Daye; Nishimura, Yusaku; Men, Ming

2016-01-01

In the present work, we investigate the fractal dimensions of 30 important stock markets from 2006 to 2013; the analysis indicates that the Hurst exponent of emerging markets shifts significantly away from the standard Brownian motion. We propose a model based on the Hurst exponent to explore the considerable profits from the predictable long-term memory. We take the transaction cost into account to justify why the market inefficiency has not been arbitraged away in the majority of cases. The empirical evidence indicates that the majority of the markets are efficient with a certain transaction cost under the no-arbitrage assumption. Furthermore, we use the Monte Carlo simulation to display "the efficient frontier" of the Hurst exponent with different transaction costs.

The quantum handshake entanglement, nonlocality and transactions

CERN Document Server

Cramer, John G

2016-01-01

This book shines bright light into the dim recesses of quantum theory, where the mysteries of entanglement, nonlocality, and wave collapse have motivated some to conjure up multiple universes, and others to adopt a "shut up and calculate" mentality. After an extensive and accessible introduction to quantum mechanics and its history, the author turns attention to his transactional model. Using a quantum handshake between normal and time-reversed waves, this model provides a clear visual picture explaining the baffling experimental results that flow daily from the quantum physics laboratories of the world. To demonstrate its powerful simplicity, the transactional model is applied to a collection of counter-intuitive experiments and conceptual problems.

Hasler-Sheetal, H.; Castorani, M. C.; Fragner, L.; Zeng, Y.; Holmer, M.; Glud, R. N.; Weckwerth, W.; Canfield, D. E.

2016-02-01

The integrated analysis of multi'omics and environmental data provides a holistic understanding of biological processes and has been proven to be challenging. Here we present our research concept for conducting multi-omics experiments and linking them to environmental data. Hypoxia, reduced light availability and species interaction - all amplified by global warming - cause a global decline of seagrasses. Metabolic mechanisms for coping with these global threats are largely unknown and multi'omics approaches can be an important approach for generating this insight. We applied GC, LC-qTOF-MS and bioinformatics to investigate the effects of environmental pressure on metabolites present in seagrasses. In a first experiment we assessed the metabolomics response of the seagrass Zostera marina towards anoxia and showed that photosynthetically derived oxygen could satisfy the oxygen demand in the leaves. But accumulation of fermentation products in the roots showed that the rhizosphere was under anoxic stress. In contrast nocturnal anoxia caused a biphasic shift in the metabolome of roots and leaves. This nocturnal reprogramming of the metabolome under anoxia indicates a mitigation mechanism to avoid the toxic effects. A pathway enrichment analysis proposes the alanine shunt, the GABA shunt and the 2-oxoglutarate shunt as such mitigation mechanisms that alleviate pyruvate levels and lead to carbon and nitrogen storage during anoxia. In a second experiment, varying light exposure and species interaction of Z. marina with the blue mussel Mytilus edulis - a co-occurring species in seagrass systems - resulted in treatment specific metabolic fingerprints in seagrass. Light modified the metabolic fingerprint expressed in Z. marina to the presence of mussels, indicating varying physiological responses to mussels in normal and low light regimes. Multivariate data-analysis indicated light exposure as main driver (45%) and mussel presence as minor driver (13%) for the metabolic

Transformational and transactional leadership skills for mental health teams.

Science.gov (United States)

Corrigan, P W; Garman, A N

1999-08-01

Many treatments for persons with severe mental illness are provided by mental health teams. Team members work better when led by effective leaders. Research conducted by organizational psychologists, and validated on mental health teams, have identified a variety of skills that are useful for these leaders. Bass (1990, 1997) identified two sets of especially important skills related to transformational and transactional leadership. Leaders using transformational skills help team members to view their work from more elevated perspectives and develop innovative ways to deal with work-related problems. Skills related to transformational leadership promote inspiration, intellectual stimulation, individual consideration, participative decision making, and elective delegation. Mental health and rehabilitation teams must not only develop creative and innovative programs, they must maintain them over time as a series of leader-team member transactions. Transactional leadership skills include goal-setting, feedback, and reinforcement strategies which help team members maintain effective programs.

Corporate Governance of Sugar Mills in East Java: A Transaction Cost Economics Perspective

Directory of Open Access Journals (Sweden)

Ahmad Erani Yustika

2007-01-01

Full Text Available Despite Indonesia’s overall achievements during the past two decades%2C the economy is encountering a series of problems. One of the biggest challenges is the unsatisfactory performance of the state-owned enterprises (SOEs. Subsidisies and uncovered loans to the SOEs have drained the government’s fiscal resources%2C and the signing off of employees creates many social problems. Compared with the SOEs in other sectors%2C state-owned sugar mills face more serious crises which not only jeopardise the social fabric%2C but also endanger the production. Research results strengthen the statement that the basic problem in sugar mills is management inefficiency resulting in high transaction costs. This research compares the transaction costs between state-owned (Ngadiredjo and privately-owned (Kebon Agung sugar mills. The study shows that in Kebon Agung Sugar Mill transaction costs are higher than production costs%2C while in Ngadiredjo Sugar Mill the reverse is true. However%2C the high transaction costs in Kebon Agung Sugar Mill cannot be attributed directly to inefficient institutions%2C because Ngadiredjo Sugar Mill incurred high costs for plants%2C land preparation%2C and fertilizer%2C which decreased the proportion of transaction costs. If analyzed in detail%2C the following facts are revealed: (i market transaction costs in Kebon Agung Sugar Mill are higher than in Ngadiredjo Sugar Mill. This is because Kebon Agung Sugar Mill has established cooperation with sugarcane farmers in the form of extensions and transport subsidies; and (ii the political transaction costs proportion in Ngadiredjo Sugar Mill is higher than in Kebon Agung Sugar Mill because of the imposition of many ‘illegal’ fees.

Can we develop land use policy that balances the conflicting views of stakeholders in a catchment while moving toward long term sustainability? Adaptive management provides a strategy for this whereby measures of catchment performance are compared against performance goals in order to progressively improve policy. However, the feedback loop of adaptive management is often slow and irreversible impacts may result before policy has been adapted. In contrast, integrated modelling of future land use policy provides rapid feedback and potentially improves the chance of avoiding unwanted collapse events. Replacing measures of catchment performance with modelled catchment performance has usually required the dynamic linking of many models, both biophysical and socio-economic—and this requires much effort in software development. As an alternative, we propose the use of variable environmental intensity (defined as the ratio of environmental impact over economic output) in a loose coupling of models to provide a sufficient level of integration while avoiding significant effort required for software development. This model construct was applied to the Motueka Catchment of New Zealand where several biophysical (riverine water quantity, sediment, E. coli faecal bacteria, trout numbers, nitrogen transport, marine productivity) models, a socio-economic (gross output, gross margin, job numbers) model, and an agent-based model were linked. An extreme set of land use scenarios (historic, present, and intensive) were applied to this modelling framework. Results suggest that the catchment is presently in a near optimal land use configuration that is unlikely to benefit from further intensification. This would quickly put stress on water quantity (at low flow) and water quality ( E. coli). To date, this model evaluation is based on a theoretical test that explores the logical implications of intensification at an unlikely extreme in order to assess the implications of likely growth

This report seeks to characterize the opportunities and challenges that arise in developing a transactive control strategy for grid-EVSE integration in various use-case scenarios in a way that provides end-user, energy market, grid, and societal benefits. A detailed review provides information about EVSE integration market trends and stakeholder activities. This is followed by an exploration of value proposition for transactive control of EVSE at both the home scale and the building/campus scale. This report will serve as a reference guide for stakeholders in the grid-EVSE integration area, illustrate potential implementations, and identify a high-value research project for overcoming the barriers and unlocking the benefits of transactive controls of EVSE. While it is not intended to specify the technical details of the transactive control solution, the report contains a list of use cases describing potential applications of transactive control of EVSE, barriers to implementing these applications, and research and development (R&D) opportunities to overcome the barriers. The use cases of transactive control of EVSE are listed in Table ES1.

European Option Pricing with Transaction Costs in Lévy Jump Environment

Directory of Open Access Journals (Sweden)

Jiayin Li

2014-01-01

Full Text Available The European option pricing problem with transaction costs is investigated for a risky asset price model with Lévy jump. By the aid of arbitrage pricing theory and the generalized Itô formula (which includes Poisson jump, the explicit solution to the risk asset price model is given. According to arbitrage-free principle, we first discretize the continuous-time model. Then, in each small time interval, the transaction costs are introduced. By using the Δ-hedging strategy, the explicit solutions of the European options pricing formula with transaction costs are given for the risky asset price model with Lévy jump.

Price Reversal Pattern of ARV Drugs: A Transaction-Cost Approach Digression

Directory of Open Access Journals (Sweden)

Frank LORNE

2015-05-01

Full Text Available A price reversal pattern of ARV drugs was noted across lower and middle income countries in that the lower-income countries have higher prices relative to higher-income countries based on a 2008-2009 Summary Report by World Health Organization. The transaction costs affecting AVR drug pricing can be broadly classified into two kinds: One between the final users and the opinion/knowledge experts, and the other between the opinion/knowledge experts and the manufacturers. Economist’s version of price discrimination needs to be modified by including transaction costs. Transaction costs also point to institution creditability factors that will affect NGO procurement.

Preliminary environmental site assessments in New York City

International Nuclear Information System (INIS)

Lundy, P.; Gasson, D.R.; Longendyke, S.T.

1991-01-01

Preliminary Environmental Site Assessments are often performed prior to real estate transactions or refinancing. These assessments are typically performed for real estate buyers, sellers and lending institutions. Undertaking a Preliminary Environmental Site Assessment in New York City can often be quite complex and time-consuming. This is due, in part, to the age and density of buildings in the city as well as the myriad of regulatory agencies with jurisdiction over environmental issues. This paper will discuss how environmental assessments are performed with a special emphasis on building in New York City. In includes hazardous wastes management for Radon, PCB's and asbestos

Two-Stage Optimal Scheduling of Electric Vehicle Charging based on Transactive Control

DEFF Research Database (Denmark)

Liu, Zhaoxi; Wu, Qiuwei; Ma, Kang

2018-01-01

In this paper, a two-stage optimal charging scheme based on transactive control is proposed for the aggregator to manage day-ahead electricity procurement and real-time EV charging management in order to minimize its total operating cost. The day-ahead electricity procurement considers both the day......-ahead energy cost and expected real-time operation cost. In the real-time charging management, the cost of employing the charging flexibility from the EV owners is explicitly modelled. The aggregator uses a transactive market to manage the real-time charging demand to provide the regulating power. A model...... predictive control (MPC) based method is proposed for the aggregator to clear the transactive market. The realtime charging decisions of the EVs are determined by the clearing of the proposed transactive market according to the realtime requests and preferences of the EV owners. As such, the aggregators...

A Case against the Legal Rules on Conflicted Interested Transactions in Colombian Corporate Law

Directory of Open Access Journals (Sweden)

Juan Antonio Gaviria

2017-07-01

Full Text Available This paper contends and explains why the Colombian corporate legal rules on conflict of interest are inefficient, proposing some legal changes. In particular, this paper poses four criticisms. First, Colombian law requires that the highest corporate body shall always authorize any transaction between the legal entity and any of its managers or controlling shareholders. Second, such authorization lacks any legal effect whenever the transaction is detrimental to the company. Third, all transactions entered into without such approval are voidable. Fourth, there are no exceptions regarding transactions among companies belonging to the same entrepreneurial group.

Roth, Alexis M; Rosenberger, Joshua G; Hensel, Devon J; Wiehe, Sarah E; Fortenberry, J Dennis; Wagner, Karla D

2016-04-01

Background Relationship characteristics and day-to-day variation in affective state have been associated with HIV risk behaviour. However, no research has assessed the impact of these factors on event-level condom use among women engaging in transactional sex. Twenty-six women engaging in transactional sex were enrolled in a prospective study of their sexual health. They completed diaries about multi-level predictors of condom use during vaginal sex twice, daily. Over 4 weeks, 18 participants reported 87 paid/traded vaginal intercourse events. Of these, 51.7% were condom protected. The majority of paid/traded events (81.5%) occurred with a non-romantic partner. After controlling for partner type, feeling in love on a given day was associated with higher odds of condom use during paid/traded sexual events, while having sex on the weekend and at night were associated with lower odds of condom use (all P≤0.05). There was a significant interaction between being in love and using condoms during transactional sex (Plove and 40% (4/10) when love was reported. In sexual events with non-romantic partners, the frequency of condom use was 43.8% (14/32) when women did not report love and 59.5% (22/37) when love was reported. Women were less likely to report protected sex with romantic partners and more likely to report protected sex with non-romantic partners when they are in love. Interventions focusing on the link between day-to-day variation in affective state on condom use may help women with risk management across partner types.

Leadership in Academic Health Centers: Transactional and Transformational Leadership.

Science.gov (United States)

Smith, Patrick O

2015-12-01

Leadership is a crucial component to the success of academic health science centers (AHCs) within the shifting U.S. healthcare environment. Leadership talent acquisition and development within AHCs is immature and approaches to leadership and its evolution will be inevitable to refine operations to accomplish the critical missions of clinical service delivery, the medical education continuum, and innovations toward discovery. To reach higher organizational outcomes in AHCs requires a reflection on what leadership approaches are in place and how they can better support these missions. Transactional leadership approaches are traditionally used in AHCs and this commentary suggests that movement toward a transformational approach is a performance improvement opportunity for AHC leaders. This commentary describes the transactional and transformational approaches, how they complement each other, and how to access the transformational approach. Drawing on behavioral sciences, suggestions are made on how a transactional leader can change her cognitions to align with the four dimensions of the transformational leadership approach.

Transaction Costs in Global Supply Chains of Manufacturing Companies

Directory of Open Access Journals (Sweden)

Philipp Bremen

2010-02-01

Full Text Available Outsourcing has advanced to an important measure that is applied broadly in operations management. Nowadays, suppliers of manufacturing companies do not only provide direct material like raw material and operational supplements but offer components and advanced modules incurring many value-adding stages. Whereas in the past companies built up local supplier networks, they recently tend to search for global sources. However, not all companies reach their expectations towards the success of global sourcing projects. Important reasons for relocating manufacturing capacities back to local suppliers or in- house manufacturing are costs for unexpected coordination activities, limited flexibility and declined or fluctuating quality. The theory of Transaction Cost Economics postulates that transaction costs of the types information, communication and coordination determine the governance structure of a supply chain, i.e. market, hybrid or firm. The objective of this paper is to analyze the cause-and-effect chain of inter-firm transaction costs concerning global sourcing. The resulting qualitative model is based on explorative multiple-case study.

Yog Raj Sood; Narayana Prasad Padhy; Hari Om Gupta

2004-01-01

Many transactions of electrical power are expected to take place due to deregulation of electrical power industry. It is important for independent power producers, independent system operator and bulk power consumers (load centers) to know and select the least cost transaction among all the feasible transactions. In this paper, selection of best possible wheeling transaction in a deregulated power system has been determined based on available transfer capability and short run marginal cost. The proposed algorithm has been tested and analyzed for IEEE-30 bus test system and hence applied to South African power industry, the results so obtained are found to be of very much practical use.

Administration and transaction cost estimates for a greenhouse gas offset system : final report

International Nuclear Information System (INIS)

2004-01-01

Canada's Climate Change Plan provides large final emitters (LFEs) with the option to meet their emission targets through the purchase of domestic greenhouse gas (GHG) offset credits. This paper presents the results of a study which identified and estimated transaction costs associated with an offset system. The cost to both proponents and governments were identified. The study also suggested ways to reduce administration and transaction costs through design options. The study considered projects involving agriculture, forests, landfill gas capture, renewable energy and energy efficiency within a potential domestic offset system. It was determined that average transaction costs per tonne range from $19 per tonne to $0.05 depending on the design choice and project type. Total administration costs did not vary more than 5 per cent between different design choices. The total system costs, which are the combination of all transaction and administration costs, are the best indicator for the potential of a project. Eight case studies were examined and costs per tonne were presented. According to the results, the best opportunities to reduce both transaction and administration costs are to choose a broad approach to baselines, boundaries and quantification; and, to allow pooling in the forestry and agriculture sectors. Transaction costs can be lowered further by reducing the frequency of monitoring and verification and allowing pre-2008 crediting. refs., tabs., figs

Analysis of Transaction Costs in Logistics and the Methodologies for Their Information Reflection for Automotive Companies

Directory of Open Access Journals (Sweden)

Ol’ga Evgen’evna Kovrizhnykh

2016-12-01

Full Text Available Transaction costs emerge in different types of logistics activities and influence the material flow and the accompanying financial and information flows; due to this fact, the information support and assessment are important tasks for the enterprise. The paper analyzes transaction costs in logistics for automotive manufacturers; according to the analysis, the level of these costs in any functional area of “logistics supply” ranges from 1.5 to 20%. These are only the official figures of transaction costs of enterprises that do not take into consideration implicit costs. Despite the growing interest in transaction costs in logistics in the latest fifteen years, this topic is covered rather poorly in Russian literature; the definition of “transaction costs” is unclear, there is no technique of their information reflection and assessment. We have developed the methods for information reflection of transaction costs that can be used by automotive enterprises. Each enterprise will have an opportunity to choose the most suitable technique for information reflection of transaction costs or to compare the level of transaction costs when using different techniques. Application of techniques for information reflection of transaction costs allows the enterprises to increase profits by optimizing and reducing costs and using their assets more effectively, to identify possible ways to improve cost parameters of their performance, to improve their efficiency and productivity; to cut out unnecessary or duplicate activities, to optimize the number of staff involved in a particular activity

Barriers to Building Energy Efficiency (BEE) promotion: A transaction costs perspective

Science.gov (United States)

Qian Kun, Queena

Worldwide, buildings account for a surprisingly high 40% of global energy consumption, and the resulting carbon footprint significantly exceeds that of all forms of transportation combined. Large and attractive opportunities exist to reduce buildings' energy use at lower costs and higher returns than in other sectors. This thesis analyzes the concerns of the market stakeholders, mainly real estate developers and end-users, in terms of transaction costs as they make decisions about investing in Building Energy Efficiency (BEE). It provides a detailed analysis of the current situation and future prospects for BEE adoption by the market's stakeholders. It delineates the market and lays out the economic and institutional barriers to the large-scale deployment of energy-efficient building techniques. The aim of this research is to investigate the barriers raised by transaction costs that hinder market stakeholders from investing in BEES. It explains interactions among stakeholders in general and in the specific case of Hong Kong as they consider transaction costs. It focuses on the influence of transaction costs on the decision-making of the stakeholders during the entire process of real estate development. The objectives are: 1) To establish an analytical framework for understanding the barriers to BEE investment with consideration of transaction costs; 2) To build a theoretical game model of decision making among the BEE market stakeholders; 3) To study the empirical data from questionnaire surveys of building designers and from focused interviews with real estate developers in Hong Kong; 4) To triangulate the study's empirical findings with those of the theoretical model and analytical framework. The study shows that a coherent institutional framework needs to be established to ensure that the design and implementation of BEE policies acknowledge the concerns of market stakeholders by taking transaction costs into consideration.

Exploring the link between environmental pollution and economic growth in EU-28 countries: Is there an environmental Kuznets curve?

Science.gov (United States)

Armeanu, Daniel; Vintilă, Georgeta; Andrei, Jean Vasile; Gherghina, Ştefan Cristian; Drăgoi, Mihaela Cristina; Teodor, Cristian

2018-01-01

This study examines the Environmental Kuznets Curve hypothesis (EKC), considering the primary energy consumption among other country-specific variables, for a panel of the EU-28 countries during the period 1990-2014. By estimating pooled OLS regressions with Driscoll-Kraay standard errors in order to account for cross-sectional dependence, the results confirm the EKC hypothesis in the case of emissions of sulfur oxides and emissions of non-methane volatile organic compounds. In addition to pooled estimations, the output of fixed-effects regressions with Driscoll-Kraay standard errors support the EKC hypothesis for greenhouse gas emissions, greenhouse gas emissions intensity of energy consumption, emissions of nitrogen oxides, emissions of non-methane volatile organic compounds and emissions of ammonia. Additionally, the empirical findings from panel vector error correction model reveal a short-run unidirectional causality from GDP per capita growth to greenhouse gas emissions, as well as a bidirectional causal link between primary energy consumption and greenhouse gas emissions. Furthermore, since there occurred no causal link between economic growth and primary energy consumption, the neo-classical view was confirmed, namely the neutrality hypothesis.

FCJ-149 Affect and Care in Intimate Transactions

Directory of Open Access Journals (Sweden)

Lone Bertelsen

2012-01-01

Full Text Available This article considers the ‘co-affective’ power of the new media artwork Intimate Transactions. This co-affective power operates at the ‘trans-subjective’ level of experience. In order to explore this level of experience the article draws on the work of Brian Massumi, Bracha Ettinger and Felix Guattari amongst others. For these thinkers the ‘trans-subjective’ level of experience, precisely because it is ‘co-affective’, holds ethical potential. The article argues for the importance of tending to ‘co-affective’ level of experience – both in designing “interactive” art, such as Intimate Transactions, and in life more generally.

Kumar, Ashwani; Gao, Wenzhong

2009-01-01

This paper proposes a new method for secure bilateral transactions determination ensuring economic power dispatch of the generators using new AC distribution factors for pool and bilateral coordinated markets. The new optimization problem considers simultaneous minimization of deviations from scheduled transactions and fuel cost of the generators in the network. The fuel cost has been obtained for hybrid market model and impact of different percentage of bilateral demand on fuel cost, generation share, and pattern of transactions has also been determined. The impact of optimally located unified power flow controller (UPFC) on the bilateral transactions, fuel cost and generation pattern has also been studied. The results have also been obtained for pool market model. The proposed technique has been applied on IEEE 24-bus reliability test system (RTS). (author)

We examine a number of types of transaction governance, viz., markets, relational transacting, and hierarchies. The model proposed in the paper integrates the concept of trust with key dimensions of transaction cost economics, being estimated with data from a sample of Georgian manufacturing industries. The main finding of the study is that trust along with traditional dimensions of transaction cost economics has a significant impact on the choice of exchange governance mode

Linking legacies: Connecting the Cold War nuclear weapons production processes to their environmental consequences

International Nuclear Information System (INIS)

1997-01-01

In the aftermath of the Cold War, the US has begun addressing the environmental consequences of five decades of nuclear weapons production. In support of this effort, the National Defense Authorization Act for Fiscal Year 1995 directed the Department of Energy (DOE) to describe the waste streams generated during each step in the production of nuclear weapons. Accordingly, this report responds to this mandate, and it is the Department's first comprehensive analysis of the sources of waste and contamination generated by the production of nuclear weapons. The report also contains information on the missions and functions of nuclear weapons facilities, on the inventories of waste and materials remaining at these facilities, as well as on the extent and characteristics of contamination in and around these facilities. This analysis unites specific environmental impacts of nuclear weapons production with particular production processes. The Department used historical records to connect nuclear weapons production processes with emerging data on waste and contamination. In this way, two of the Department's legacies--nuclear weapons manufacturing and environmental management--have become systematically linked. The goal of this report is to provide Congress, DOE program managers, non-governmental analysts, and the public with an explicit picture of the environmental results of each step in the nuclear weapons production and disposition cycle

Bilateral transaction bargaining between independent utilities under incomplete information

International Nuclear Information System (INIS)

David, A. K.; Wen, F. S.

2001-01-01

A new approach to designing bilateral power transaction bargaining models between two independent utilities in a deregulated electricity market is proposed. In the paper it is assumed that each utility (a seller or a buyer) knows its own operating costs but does not know those of its opponent. The bilateral power transaction problem is then considered as non-cooperative bargaining under incomplete information. Each participant develops its own bargaining strategy based on estimates of the opponent's operating costs and bargaining strategy. Two bargaining models are developed and examples are employed for demonstration. (Author)

Young women's perceptions of transactional sex and sexual agency: a qualitative study in the context of rural South Africa.

Evidence shows that HIV prevalence among young women in sub-Saharan Africa increases almost five-fold between ages 15 and 24, with almost a quarter of young women infected by their early-to mid-20s. Transactional sex or material exchange for sex is a relationship dynamic that has been shown to have an association with HIV infection. Using five focus group discussions and 19 in-depth interviews with young women enrolled in the HPTN 068 conditional cash transfer trial (2011-2015), this qualitative study explores young women's perceptions of transactional sex within the structural and cultural context of rural South Africa. The analysis also considers the degree to which young women perceive themselves as active agents in such relationships and whether they recognise a link between transactional sex and HIV risk. Young women believe that securing their own financial resources will ultimately improve their bargaining position in their sexual relationships, and open doors to a more financially independent future. Findings suggest there is a nuanced relationship between sex, love and gifts: money has symbolic meaning, and money transfers, when framed as gifts, indicates a young woman's value and commitment from the man. This illustrates the complexity of transactional sex; the way it is positioned in the HIV literature ignores that "exchanges" serve as fulcrums around which romantic relationships are organised. Finally, young women express agency in their choice of partner, but their agency weakens once they are in a relationship characterised by exchange, which may undermine their ability to translate perceived agency into STI and HIV risk reduction efforts. This research underscores the need to recognise that transactional sex is embedded in adolescent romantic relationships, but that certain aspects make young women particularly vulnerable to HIV. This is especially true in situations of restricted choice and circumscribed employment opportunities. HIV prevention

Alcohol Use and Transactional Sex among Women in South Africa: Results from a Nationally Representative Survey.

Directory of Open Access Journals (Sweden)

Sarah Magni

Full Text Available Transactional sex is a risk factor for HIV infection. Alcohol use may increase the risk of transactional sex. No nationally-representative studies have examined the relationship between multiple dimensions of alcohol use and transactional sex in women in South Africa. The aim of the study was to examine the relationship between alcohol dependence, binge drinking and frequency of drinking in the past month and transactional sex in adult women in South Africa.A cross-sectional study using multi-stage, cluster sampling collected data from a nationally representative sample of 5,969 women aged 16-55 years in 2012. The analysis conducted for this paper was restricted to women reporting sexual activity in the past 12 months (n = 3,594. Transactional sex was defined as having received money/gifts in exchange for sex with any sex partner in the past year. Alcohol use measures included: alcohol dependence (≥2 positive responses to the CAGE questionnaire; binge drinking (≥4 drinks for women on one occasion; and drinking frequency in the previous month. Logistic regression models were built to test the hypotheses that each dimension of alcohol use was associated with transactional sex.About 6.3% (n = 225 of sexually active women reported transactional sex. Almost a third (30.6% of sexually active women had ever drunk alcohol, and 19.2% were current (past month drinkers. Among lifetime drinkers, 28.0% were alcohol dependent and 56.6% were binge drinkers. Alcohol dependent women were twice as likely to report transactional sex (AOR 2.0, 95% CI 1.1-4.3, p<0.05 than those not alcohol dependent. Binge drinkers were 3.1 times more likely to have had transactional sex (95% CI 1.5-6.6, p<0.01 than non-binge drinkers. There was no significant relationship between frequency of drinking in the past month and transactional sex.Alcohol dependency and binge drinking are significantly associated with transactional sex in South African women.

2014-09-01

Full Text Available This paper evaluated consumers’ perceptions of Brazilian Home Broker services in the online environment. Based on the model suggested by Balasubramanian, Konana and Menon (2003, the effects of relevant online consumer behavior constructs on customer satisfaction with the service were analyzed. Constructs such as perceived operational competence, willingness to trust and perceived environmental security were employed, in a model fully mediated by trust. A questionnaire with scales previously used in literature was employed to measure the relevant constructs and structural equations applied to analyze the relationships found. Results show a strong relationship between perceived environment security and perceived operational competence, indicating that trust formation precedes satisfaction in online financial services transactions within the Brazilian context.

Kim, Young Bin; Kim, Jun Gi; Kim, Wook; Im, Jae Ho; Kim, Tae Hyeong; Kang, Shin Jin; Kim, Chang Hun

2016-01-01

This paper proposes a method to predict fluctuations in the prices of cryptocurrencies, which are increasingly used for online transactions worldwide. Little research has been conducted on predicting fluctuations in the price and number of transactions of a variety of cryptocurrencies. Moreover, the few methods proposed to predict fluctuation in currency prices are inefficient because they fail to take into account the differences in attributes between real currencies and cryptocurrencies. This paper analyzes user comments in online cryptocurrency communities to predict fluctuations in the prices of cryptocurrencies and the number of transactions. By focusing on three cryptocurrencies, each with a large market size and user base, this paper attempts to predict such fluctuations by using a simple and efficient method.

Genetic moderation of transactional relations between parenting practices and child self-regulation.

Cho, Junhan; Kogan, Steven M; Brody, Gene H

2016-10-01

The present study addressed the ways in which parent and child dopamine D4 receptor (DRD4) genotypes jointly moderate the transactional relations between parenting practices and child self-regulation. African American children (N = 309) and their parents provided longitudinal data spanning child ages 11 to 15 years and a saliva sample from which variation at DRD4 was genotyped. Based on the differential susceptibility perspective, this study examined moderation effects of DRD4 status on (a) the extent to which parenting practices affect child self-regulation and (b) the extent to which child self-regulation, as an environmental influence on the parent, affects parenting behavior. Results indicated that responsive-supportive parenting interacted with children's DRD4 status to influence increases in child self-regulation. Also, child self-regulation interacted with parent's DRD4 status to predict changes in parenting practices. Both Gene × Environment effects conformed to a differential susceptibility model in which parents' and children's DRD4 genes operated to increase environmental sensitivity "for better and for worse."

2016-12-01

This synthesis article joins the authors of the special issue "Gender perspectives in resilience, vulnerability and adaptation to global environmental change" in a common reflective dialogue about the main contributions of their papers. In sum, here we reflect on links between gender and feminist approaches to research in adaptation and resilience in global environmental change (GEC). The main theoretical contributions of this special issue are threefold: emphasizing the relevance of power relations in feminist political ecology, bringing the livelihood and intersectionality approaches into GEC, and linking resilience theories and critical feminist research. Empirical insights on key debates in GEC studies are also highlighted from the nine cases analysed, from Europe, the Americas, Asia, Africa and the Pacific. Further, the special issue also contributes to broaden the gender approach in adaptation to GEC by incorporating research sites in the Global North alongside sites from the Global South. This paper examines and compares the main approaches adopted (e.g. qualitative or mixed methods) and the methodological challenges that derive from intersectional perspectives. Finally, key messages for policy agendas and further research are drawn from the common reflection.

Determinants and Effects of Logistics Costs in Container Ports: The Transaction Cost Economics Perspective

Directory of Open Access Journals (Sweden)

Hyuk-soo Cho

2014-08-01

Full Text Available Many countries seek to become a global logistics center linking major trading ports. They are competitively constructing container ports. The aggressive competition creates overcapacity situation in the container port sector. Massive investments are required to construct container ports with terminals, docks, storage areas and hinterlands. Nevertheless, it is not easy for container ports to have sufficient container cargo volumes to justify the massive investments. Therefore, container ports of individual countries are required to develop effective strategies to have enough traffic volumes. Based on country-level analysis, this study is designed to investigate empirically internal capabilities and external environments of logistics costs and traffic volumes in individual container ports. A theoretical foundation, the transaction cost economics (TCE is applied to support and explain empirical findings.

Present econophysics models are usually employed on presumed random networks of interacting agents, and only some macroscopic properties (e.g. the resulting wealth distribution are compared to real-world data. In this paper, we analyze Bitcoin, which is a novel digital currency system, where the complete list of transactions is publicly available. Using this dataset, we reconstruct the network of transactions and extract the time and amount of each payment. We analyze the structure of the transaction network by measuring network characteristics over time, such as the degree distribution, degree correlations and clustering. We find that linear preferential attachment drives the growth of the network. We also study the dynamics taking place on the transaction network, i.e. the flow of money. We measure temporal patterns and the wealth accumulation. Investigating the microscopic statistics of money movement, we find that sublinear preferential attachment governs the evolution of the wealth distribution. We report a scaling law between the degree and wealth associated to individual nodes.

Linear versus quadratic portfolio optimization model with transaction cost

Science.gov (United States)

Razak, Norhidayah Bt Ab; Kamil, Karmila Hanim; Elias, Siti Masitah

2014-06-01

Optimization model is introduced to become one of the decision making tools in investment. Hence, it is always a big challenge for investors to select the best model that could fulfill their goal in investment with respect to risk and return. In this paper we aims to discuss and compare the portfolio allocation and performance generated by quadratic and linear portfolio optimization models namely of Markowitz and Maximin model respectively. The application of these models has been proven to be significant and popular among others. However transaction cost has been debated as one of the important aspects that should be considered for portfolio reallocation as portfolio return could be significantly reduced when transaction cost is taken into consideration. Therefore, recognizing the importance to consider transaction cost value when calculating portfolio' return, we formulate this paper by using data from Shariah compliant securities listed in Bursa Malaysia. It is expected that, results from this paper will effectively justify the advantage of one model to another and shed some lights in quest to find the best decision making tools in investment for individual investors.

Asian Option Pricing with Monotonous Transaction Costs under Fractional Brownian Motion

Directory of Open Access Journals (Sweden)

Di Pan

2013-01-01

Full Text Available Geometric-average Asian option pricing model with monotonous transaction cost rate under fractional Brownian motion was established. The method of partial differential equations was used to solve this model and the analytical expressions of the Asian option value were obtained. The numerical experiments show that Hurst exponent of the fractional Brownian motion and transaction cost rate have a significant impact on the option value.

Fraud Detection in Credit Card Transactions; Using Parallel Processing of Anomalies in Big Data

Directory of Open Access Journals (Sweden)

Mohammad Reza Taghva

2016-10-01

Full Text Available In parallel to the increasing use of electronic cards, especially in the banking industry, the volume of transactions using these cards has grown rapidly. Moreover, the financial nature of these cards has led to the desirability of fraud in this area. The present study with Map Reduce approach and parallel processing, applied the Kohonen neural network model to detect abnormalities in bank card transactions. For this purpose, firstly it was proposed to classify all transactions into the fraudulent and legal which showed better performance compared with other methods. In the next step, we transformed the Kohonen model into the form of parallel task which demonstrated appropriate performance in terms of time; as expected to be well implemented in transactions with Big Data assumptions.

Resilient data staging through MxN distributed transactions.

Energy Technology Data Exchange (ETDEWEB)

Schwan, Karsten (Georgia Institute of Technology, Atlanta, GA); Oldfield, Ron A.; Lofstead, Gerald Fredrick, II; Dayal, Jai (Georgia Institute of Technology, Atlanta, GA)

Scientific computing-driven discoveries are frequently driven from workflows that use persistent storage as a staging area for data between operations. With the bad and progressively worse bandwidth vs. data size issues as we continue towards exascale, eliminating persistent storage through techniques like data staging will both enable these workflows to continue online, but also enable more interactive workflows reducing the time to scientific discoveries. Data staging has shown to be an effective way for applications running on high-end computing platforms to offload expensive I/O operations and to manage the tremendous amounts of data they produce. This data staging approach, however, lacks the ACID style guarantees traditional straight-to-disk methods provide. Distributed transactions are a proven way to add ACID properties to data movements, however distributed transactions follow 1xN data movement semantics, where our highly parallel HPC environments employ MxN data movement semantics. In this paper we present a novel protocol that extends distributed transaction terminology to include MxN semantics which allows our data staging areas to benefit from ACID properties. We show that with our protocol we can provide resilient data staging with a limited performance penalty over current data staging implementations.

Transactional Sex among Youths in Post-conflict Liberia

Kennedy, Stephen B.; Barbu, Ernlee M.; Nagbe, Wede; Seekey, Wede; Sirleaf, Prince; Perry, Oretha; Martin, Roland B.; Sosu, Fred

2011-01-01

This paper presents findings on sexual risk behaviours of Liberian youths based on five focus-group discussions conducted with 6th and 7th graders (n=36) attending an elementary/middle school in Monrovia, Liberia. The purpose of the focus-group discussions was to gain an understanding of the sexual behaviours of in-school Liberian adolescents. The focus-group discussions were part of a larger study to adapt an evi-dence-based HIV-prevention intervention—Making Proud Choices!—for in-school youths. Post-conflict conditions were discussed as a contributor to the emergence of high-risk sexual behaviours, including transactional sex, sexual violence, and lack of condom-use. Transactional sex was often described by the focus-group participants as occurring between young females and older, more financially-secure males to obtain cash, food, clothing, western commodities, and school-fees and was often encouraged by parents and promoted by peers. The findings also indicate that female adolescents make choices to engage in transactional sex to gain access to a continuum of material and consumer needs. These findings suggest that individual risk-taking behaviours are nested within complex sexual economies and that HIV-prevention interventions should be considered that leverage females’ agency and control.

Efficient Mobile Client Caching Supporting Transaction Semantics

Directory of Open Access Journals (Sweden)

IlYoung Chung

2000-05-01

Full Text Available In mobile client-server database systems, caching of frequently accessed data is an important technique that will reduce the contention on the narrow bandwidth wireless channel. As the server in mobile environments may not have any information about the state of its clients' cache(stateless server, using broadcasting approach to transmit the updated data lists to numerous concurrent mobile clients is an attractive approach. In this paper, a caching policy is proposed to maintain cache consistency for mobile computers. The proposed protocol adopts asynchronous(non-periodic broadcasting as the cache invalidation scheme, and supports transaction semantics in mobile environments. With the asynchronous broadcasting approach, the proposed protocol can improve the throughput by reducing the abortion of transactions with low communication costs. We study the performance of the protocol by means of simulation experiments.

This document details the development and testing of market-based transactive controls for building heating, ventilating and air conditioning (HVAC) systems. These controls are intended to serve the purposes of reducing electricity use through conservation, reducing peak building electric demand, and providing demand flexibility to assist with power system operations. This report is the summary of the first year of work conducted under Phase 1 of the Clean Energy and Transactive Campus Project. The methods and techniques described here were first investigated in simulation, and then subsequently deployed to a physical testbed on the Pacific Northwest National Laboratory (PNNL) campus for validation. In this report, we describe the models and control algorithms we have developed, testing of the control algorithms in simulation, and deployment to a physical testbed. Results from physical experiments support previous simulation findings, and provide insights for further improvement.

Young women’s perceptions of transactional sex and sexual agency: a qualitative study in the context of rural South Africa

Directory of Open Access Journals (Sweden)

Meghna Ranganathan

2017-08-01

Full Text Available Abstract Background Evidence shows that HIV prevalence among young women in sub-Saharan Africa increases almost five-fold between ages 15 and 24, with almost a quarter of young women infected by their early-to mid-20s. Transactional sex or material exchange for sex is a relationship dynamic that has been shown to have an association with HIV infection. Methods Using five focus group discussions and 19 in-depth interviews with young women enrolled in the HPTN 068 conditional cash transfer trial (2011–2015, this qualitative study explores young women’s perceptions of transactional sex within the structural and cultural context of rural South Africa. The analysis also considers the degree to which young women perceive themselves as active agents in such relationships and whether they recognise a link between transactional sex and HIV risk. Results Young women believe that securing their own financial resources will ultimately improve their bargaining position in their sexual relationships, and open doors to a more financially independent future. Findings suggest there is a nuanced relationship between sex, love and gifts: money has symbolic meaning, and money transfers, when framed as gifts, indicates a young woman’s value and commitment from the man. This illustrates the complexity of transactional sex; the way it is positioned in the HIV literature ignores that “exchanges” serve as fulcrums around which romantic relationships are organised. Finally, young women express agency in their choice of partner, but their agency weakens once they are in a relationship characterised by exchange, which may undermine their ability to translate perceived agency into STI and HIV risk reduction efforts. Conclusions This research underscores the need to recognise that transactional sex is embedded in adolescent romantic relationships, but that certain aspects make young women particularly vulnerable to HIV. This is especially true in situations of

A Method for Visualizing Transaction Logs of a Faceted OPAC

Directory of Open Access Journals (Sweden)

Xi Niu

2010-12-01

Full Text Available The authors introduce a method for visualizing user transaction logs from a library catalog application. Simple visualization supporting intuitive or qualitative analysis to quickly make sense of complicated patterns can be a useful supplement or alternative to more common quantitative analysis. To this end, a visual flowchart is created illustrating an individual user session. This visualization can be used to qualitatively grasp user behavior within the application, possibly as an aid to identifying patterns or clusters of use. These flowcharts are created by automatically pre-processing apache transaction logs into an XML representation of meaningful user actions, which are then converted via JavaScript in a web browser to HTML table based flowcharts. The particular toolkit introduced is named Visualization for Understanding Transaction Logs (VUTL, and is available with an open source license. The toolkit has been prototyped with logs from the catalog applications of several academic and one public library.

Exploring the link between environmental pollution and economic growth in EU-28 countries: Is there an environmental Kuznets curve?

Directory of Open Access Journals (Sweden)

Daniel Armeanu

Full Text Available This study examines the Environmental Kuznets Curve hypothesis (EKC, considering the primary energy consumption among other country-specific variables, for a panel of the EU-28 countries during the period 1990-2014. By estimating pooled OLS regressions with Driscoll-Kraay standard errors in order to account for cross-sectional dependence, the results confirm the EKC hypothesis in the case of emissions of sulfur oxides and emissions of non-methane volatile organic compounds. In addition to pooled estimations, the output of fixed-effects regressions with Driscoll-Kraay standard errors support the EKC hypothesis for greenhouse gas emissions, greenhouse gas emissions intensity of energy consumption, emissions of nitrogen oxides, emissions of non-methane volatile organic compounds and emissions of ammonia. Additionally, the empirical findings from panel vector error correction model reveal a short-run unidirectional causality from GDP per capita growth to greenhouse gas emissions, as well as a bidirectional causal link between primary energy consumption and greenhouse gas emissions. Furthermore, since there occurred no causal link between economic growth and primary energy consumption, the neo-classical view was confirmed, namely the neutrality hypothesis.

Heather Empey

2011-01-01

Full Text Available As discussions continue about the changing nature of reference service in academic libraries, the Geoffrey R. Weller Library determined that more detailed information on what was happening at the Reference Desk was needed. During the 2006/07 academic year, transactions at the Reference Desk were analyzed to determine when they occurred (both during the week and during the academic year, the length of time the transactions took, the categories of the transactions, what sources were used and whether or not instruction was provided as part of the transaction. Another round of data was gathered in September 2009 to determine if use patterns had changed. Transactions at the Reference Desk were generally conducted in person, took either <1 min. or between 1-5 min. to answer, and occurred most often on Mon-Thurs between 11am-5pm. Between September 2006 and September 2009, specific title and research categories of questions decreased by 6% and directional and technical help categories of questions increased by 9%. There was also a decrease in the level of instruction being given. As a result of this research, service hours have been reduced and the on-going data collection at the Reference Desk has become more detailed to allow for ongoing analysis.

Transactional approach in assessment of operational performance of companies in transport infrastructure

Energy Technology Data Exchange (ETDEWEB)

Dubrovsky, V.; Yaroshevich, N.; Kuzmin, E.

2016-07-01

Offer an alternative method to assess operational performance of companies in transport infrastructure of a region by making a comparison between transaction costs. The method is supposed to be a cross-functional and possibly applied to an analysis of economic entities of a different order (country, region, sector, companies) while evaluating “viscosity” / complexity of the outside and the inside. The paper includes an analysis of various methodological approaches to assess a development level of the transport infrastructure in a region. Within the author's approach and for purposed of the research, an index of transaction capacity or the transactionalness index is proposed, which determines a level of transaction costs calculated against the cost of production and revenue. The approach is piloted using the region-wise consolidated financial data of companies involved in the Russian transport infrastructure for 2005/2013. The proposed alternative way to measure corporate operating efficiency has proved its academic consistency. A specific comparison between the transaction costs using the transactionalness index allows first to identify companies or regions/sectors, where there is excess complexity of economical communication in bargaining. Secondly, the index does not only point out indirectly to a degree of development in the institutional environment, but also the infrastructure (the transport one in the example given). Third, the transactionalness level may say of uncertainty and risks. As an addition to theoretical and methodological aspects of transaction costs, the authors justify an approach to their size estimation, as well as their differentiation dividing them into two groups: those of a natural type and a background type. In a course of their discussion, the authors have concluded that there are such transaction costs in place, which are standard in a manner of speaking. There is a discussion whether it is scientifically reasonable to use an

Giving or receiving something for sex: a cross-sectional study of transactional sex among Ugandan university students.

Directory of Open Access Journals (Sweden)

Vikas Choudhry

Full Text Available This study sought to determine the prevalence of transactional sex among university students in Uganda and to assess the possible relationship between transactional sex and sexual coercion, physical violence, mental health, and alcohol use.In 2010, 1954 undergraduate students at a Ugandan university responded to a self-administered questionnaire that assessed mental health, substance use, physical violence and sexual behaviors including sexual coercion and transactional sex. The prevalence of transactional sex was assessed and logistic regression analysis was performed to measure the associations between various risk factors and reporting transactional sex.Approximately 25% of the study sample reported having taken part in transactional sex, with more women reporting having accepted money, gifts or some compensation for sex, while more men reporting having paid, given a gift or otherwise compensated for sex. Sexual coercion in men and women was significantly associated with having accepted money, gifts or some compensation for sex. Men who were victims of physical violence in the last 12 months had higher probability of having accepted money, gifts or some compensation for sex than other men. Women who were victims of sexual coercion reported greater likelihood of having paid, given a gift or otherwise compensated for sex. Respondents who had been victims of physical violence in last 12 months, engaged in heavy episodic drinking and had poor mental health status were more likely to have paid, given a gift or otherwise compensated for sex.University students in Uganda are at high risk of transactional sex. Young men and women may be equally vulnerable to the risks and consequences of transactional sex and should be included in program initiatives to prevent transactional sex. The role of sexual coercion, physical violence, mental health, and alcohol use should be considered when designing interventions for countering transactional sex.

Socioeconomic characterization of regions through the lens of individual financial transactions

People are increasingly leaving digital traces of their daily activities through interacting with their digital environment. Among these traces, financial transactions are of paramount interest since they provide a panoramic view of human life through the lens of purchases, from food and clothes to sport and travel. Although many analyses have been done to study the individual preferences based on credit card transaction, characterizing human behavior at larger scales remains largely unexplored. This is mainly due to the lack of models that can relate individual transactions to macro-socioeconomic indicators. Building these models, not only can we obtain a nearly real-time information about socioeconomic characteristics of regions, usually available yearly or quarterly through official statistics, but also it can reveal hidden social and economic structures that cannot be captured by official indicators. In this paper, we aim to elucidate how macro-socioeconomic patterns could be understood based on individual financial decisions. To this end, we reveal the underlying interconnection of the network of spending leveraging anonymized individual credit/debit card transactions data, craft micro-socioeconomic indices that consists of various social and economic aspects of human life, and propose a machine learning framework to predict macro-socioeconomic indicators.

Are transaction taxes a cause of financial instability?

Science.gov (United States)

Fontini, Fulvio; Sartori, Elena; Tolotti, Marco

2016-05-01

We analyze a stylized market where N boundedly rational agents may decide to trade or not a share of a risky asset at subsequent trading dates. Agents' payoff depends on returns, which are endogenously determined taking into account observed and forecasted demand and an exogenous transaction tax. We study the time evolutions of demand, returns and market activity. We show that the introduction of a transaction tax generally helps in reducing variability of returns and market activity. On the other hand, there are market conditions under which a low taxation may lead the market into a very unstable phase characterized by the fluctuation of the fundamentals around two different regimes; indeed, under these circumstances, heteroscedasticity of time series is detected and statistically analyzed.

Hwan Jin Kim

2016-06-01

Full Text Available This paper examines the impact of two main alliance motivation theories, transaction cost economics (TCE and resource based view (RBV, on alliance processes among Korean manufacturing high-tech ventures. Results show that TCE and RBV are complimentarily explaining the formation of inter-firm alliances. TCE variables are more related with alliance partner characteristics while RBV is more linked with partner capabilities. Both show positive effects on performance. No significant effect is found on determining an alliance governance structure. While selecting appropriate technological alliance partners show positive effects on performance, no significant effect is found between alliance governance structure and performance. Factors of both theories impacting each alliance stage and analytical explanations of such impacts are discussed.

Aziz Saliza Abdul

2017-01-01

Full Text Available Volume of transaction is specifically referring to number of clients or return forms dealing by tax agents/preparers. This variable does play role even though there is less empirical evidence on this matter. This paper is basically to explore the effect of volume of transaction that could possibly influence the acceptance of tax e-filing system as it did in other areas of transaction i.e. court cases. Undoubtedly, it is proved to be significantly influenced the behavioural intention towards tax e-filing acceptability in Malaysia. The tax agents/preparers are randomly selected in this study from the list provided in the Inland Revenue Board of Malaysia (IRBM website. The responds are analysed via Partial Least Square (PLS method which produce the significant results among the low and high volume of transaction of tax e-filing which support the fact that volume does matter in the decision of acceptability of tax e-filing system in Malaysia.

Financial Transaction Tax: Determination of Economic Impact Under DSGE Model

Directory of Open Access Journals (Sweden)

Veronika Solilová

2015-01-01

Full Text Available The discussion about the possible taxation of the financial sector has started in the European Union as a result of the financial crisis which has spread to the Europe from the United States in 2008 and consequently of the massive financial interventions by governments made in favour of the financial sector. On 14 February 2013, after rejection of the draft of the directive introducing a common system of financial transaction tax in 2011, the European Commission introduced the financial transaction tax through enhanced cooperation. The aim of the paper is to research economic impact of financial transaction tax on EU (EU27 or EU11 with respect to the DSGE model which was used for the determination of impacts. Based on our analysis the DSGE model can be considered as underestimated in case of the impact on economic growth and an overestimated in case of the revenue collection. Particularly, the overall impact of the financial transaction tax considering cascade effects of securities (tax rate 2.2% and derivatives (tax rate 0.2% is ranged between −4.752 and 1.472 percent points of GDP. And further, is assumed that the relocation effects of business/trade can be in average 40% causes a decline of expected tax revenues in the amount of 13bn EUR. Thus, at a time of fragile economic growth across the EU and the increased risk of recession in Europe, the introduction of the FTT should be undesirable.

Studies have shown that reducing exposure to triggers such as air pollutants can reduce symptoms and the need for medication in asthma patients. However, systems that track asthma are generally not integrated with those that track environmental hazards related to asthma. Tlvs lack of integration hinders public health awareness and responsiveness to these environmental triggers. The current study is a collaboration between health and environmental professionals to utilize NASA-derived environmental data to develop a decision support system (DSS) for asthma prediction, surveillance, and intervention. The investigators link asthma morbidity data from the University of Mississippi Medical Center (UMMC) and Mississippi Department of Health (MDH) with air quality data from the Mississippi Department of Environmental Quality (MDEQ) and remote sensing data from NASA. Daily ambient environmental hazard data for PM2.5 and ozone are obtained from the MDEQ air quality monitoring locations and are combined with remotely sensed data from NASA to develop a state-wide spatial and time series profile of environmental air quality. These data are then used to study the correlation of these measures of air quality variation with the asthma exacerbation incidence throughout the state over time. The goal is to utilize these readily available measures to allow real-time risk assessment for asthma exacerbations. GeoMedStat, a DSS previously developed for biosurveillance, will integrate these measures to monitor, analyze and report the real-time risk assessment for asthma exacerbation throughout the state.

Scratch that itch: revisiting links between self-directed behaviour and parasitological, social and environmental factors in a free-ranging primate.

Duboscq, Julie; Romano, Valéria; Sueur, Cédric; MacIntosh, Andrew J J

Different hypotheses explain variation in the occurrence of self-directed behaviour such as scratching and self-grooming: a parasite hypothesis linked with ectoparasite load, an environmental hypothesis linked with seasonal conditions and a social hypothesis linked with social factors. These hypotheses are not mutually exclusive but are often considered separately. Here, we revisited these hypotheses together in female Japanese macaques ( Macaca fuscata fuscata ) of Kōjima islet, Japan. We input occurrences of scratching and self-grooming during focal observations in models combining parasitological (lice load), social (dominance rank, social grooming, aggression received and proximity), and environmental (rainfall, temperature and season) variables. Using an information-theory approach, we simultaneously compared the explanatory value of models against each other using variation in Akaike's information criterion and Akaike's weights. We found that evidence for models with lice load, with or without environmental-social parameters, was stronger than that for other models. In these models, scratching was positively associated with lice load and social grooming whereas self-grooming was negatively associated with lice load and positively associated with social grooming, dominance rank and number of female neighbours. This study indicates that the study animals scratch primarily because of an immune/stimulus itch, possibly triggered by ectoparasite bites/movements. It also confirms that self-grooming could act as a displacement activity in the case of social uncertainty. We advocate that biological hypotheses be more broadly considered even when investigating social processes, as one does not exclude the other.

This investigation examined the mutual influences between structured parenting and child social wariness during toddlerhood using a longitudinal adoption design. The sample consisted of 361 adoption-linked families, each including an adopted child, adoptive parents, and a birth mother. Heightened social wariness in children at age 18 months predicted reduced levels of observed structured parenting (i.e., less directive parenting with fewer commands and requests) in adoptive mothers at age 27 months. Adoptive fathers’ lower structured parenting at age 18 months predicted subsequent elevation in child social wariness. Birth mothers’ history of fear-related anxiety disorders was not associated with child social wariness. Findings highlight the role of dynamic family transactions in the development of social wariness during toddlerhood. PMID:23448430

The increased penetration of renewable energy has significantly changed the conditions and the operational timing of the electricity grid. More flexible, faster ramping resources are needed to compensate for the uncertainty and variability introduced by renewable energy. Distributed energy resources (DERs) such as distributed generators, energy storage, and controllable loads could help manage the power grid in terms of both economic efficiency and operational reliability. In order to realize the benefits of DERs, coordination and control approaches must be designed to enable seamless integration of DERs into the power grid. Transactive coordination and control is a new approach for DER integration, where individual resources are automated and engaged through market interaction. Transactive approaches use economic signals—prices or incentives—to engage DERs. These economic signals must reflect the true value of the DER contributions, so that they seamlessly and equitably compete for the opportunities that today are only available to grid-owned assets. Value signals must be communicated to the DERs in near-real time, the assets must be imbued with new forms of distributed intelligence and control to take advantage of the opportunities presented by these signals, and they must be capable of negotiating and transacting a range of market-driven energy services. The concepts of transactive energy systems are not new, but build upon evolutionary economic changes in financial and electric power markets. These concepts also recognize the different regional structures of wholesale power markets, electricity delivery markets, retail markets, and vertically integrated service provider markets. Although transactive energy systems are not revolutionary, they will be transformational in their ability to provide flexibility and operational efficiency. A main goal of this research is to establish useful foundation for analysis of transactive energy systems and to facilitate

2017-10-01

The requirement for smooth information such as buying and selling is essential for commodity warehouse receipt system such as dried seaweed and their stakeholders to transact for an operational transaction. Transactions of buying or selling a commodity warehouse receipt system are a risky process due to the fluctuations in dynamic commodity prices. An integrated system to determine the condition of the real time was needed to make a decision-making transaction by the owner or prospective buyer. The primary motivation of this study is to propose computational methods to trace market tendency for either buying or selling processes. The empirical results reveal that feature selection gain ratio and k-NN outperforms other forecasting models, implying that the proposed approach is a promising alternative to the stock market tendency of warehouse receipt document exploration with accurate level rate is 95.03%.

A Complex Estimation Function based on Community Reputation for On-line Transaction Systems

Directory of Open Access Journals (Sweden)

Yu Yang

2012-09-01

Full Text Available A reputation management system is crucial in online transaction systems, in which a reputation function is its central component. We propose a generalized set-theoretic reputation function in this paper, which can be configured to meet various assessment requirements of a wide range of reputation scenarios encountered in online transaction nowadays. We analyze and verify tolerance of this reputation function against various socio-communal reputation attacks. We find the function to be dynamic, customizable and tolerant against different attacks. As such it can serve well in many online transaction systems such as e-commerce websites, online group activities, and P2P systems.

Who Spends Money to Play for Free? Identifying Who Makes Micro-transactions on Social Casino Games (and Why).

Science.gov (United States)

Kim, Hyoun S; Hollingshead, Samantha; Wohl, Michael J A

2017-06-01

Social casino games are online gambling-like games found on social networking sites. They are initially free to play, however, players are encouraged to make micro-transactions (i.e., in-game purchases) for additional game credits or functionality. As a result, they generate billions of dollars in revenue. Yet, little is known as to who purchases virtual credits, let alone why. In the present research, we assessed whether there are individual differences (impulsivity, reward sensitivity, competitiveness, and problem gambling severity) between who is and who is not likely to make micro-transactions during social casino game play. Moreover, we examined possible motivations for making micro-transactions (e.g., extend play, win back lost credits) and whether the individual difference variables of interest predict reported motivation(s) for making micro-transactions. Results showed that social casino gamers who engaged in micro-transactions reported significantly higher levels of impulsivity, reward sensitivity and problem gambling severity, but not competitiveness. In terms of motivation to make micro-transactions, desire to extend play was endorsed most frequently, followed by a desire to access additional features, chasing lost credits, and to speed up play. Lastly, among participants who made micro-transactions, reward sensitivity predicted making micro-transactions to chase lost credits. These results suggest the personality make-up of social casino gamers is important to understand who is likely to make micro-transactions as well as their motivation to do so-information that could prove useful for regulation of the industry.

BIX Certificates: Cryptographic Tokens for Anonymous Transactions Based on Certificates Public Ledger

Directory of Open Access Journals (Sweden)

Sead Muftic

2016-12-01

Full Text Available With the widespread use of Internet, Web, and mobile technologies, a new category of applications and transactions that requires anonymity is gaining increased interest and importance. Examples of such new applications are innovative payment systems, digital notaries, electronic voting, documents sharing, electronic auctions, medical applications, and many others. In addition to anonymity, these applications and transactions also require standard security services: identification, authentication, and authorization of users and protection of their transactions. Providing those services in combination with anonymity is an especially challenging issue, because all security services require explicit user identification and authentication. To solve this issue and enable applications with security and also anonymity we introduce a new type of cryptographically encapsulated objects called BIX certificates. “BIX” is an abbreviation for “Blockchain Information Exchange.” Their purpose is equivalent to X.509 certificates: to support security services for users and transactions, but also enhanced with anonymity. This paper describes the structure and attributes of BIX certificate objects and all related protocols for their creation, distribution, and use. The BIX Certification Infrastructure (BCI as a distributed public ledger is also briefly described.

Practice points on three aspects of oil and gas property transactions - operatorship, confidentiality and title review

International Nuclear Information System (INIS)

Edwards, P.D.

1999-01-01

Practice points regarding three aspects of oil and gas property transactions were described. The first topic dealt with purchase and sale transactions and how to determine which party is entitled to act as the Operator following the sale of the Operator's interest. The second topic addressed issues of confidentiality in connection with oil and gas transactions. The final point discussed contractual provisions relating to title defects, along with their many variations and legal consequences. All three of these topics present issues which give rise to a surprising number of disputes, but which frequently receive only cursory attention in the negotiation and documentation of oil and gas transactions

The View from the Top of the Mountain: Building a Community of Practice with the GridWise Transactive Energy Framework

Energy Technology Data Exchange (ETDEWEB)

Forfia, David; Knight, Mark; Melton, Ron

2016-05-01

The topic of “transactive energy” has received growing attention over the past eighteen months. It has been a part, for example, of the NY Reforming the Energy Vision discussions and the topic of activities such as the National Institute of Standards Transactive Energy Challenge. The growing discussion stems from the realization that new approaches are needed to efficiently and reliably integrate growing numbers of distributed energy resources. In anticipation of the applicability of transactive energy systems to emerging challenges in Grid integration, the GridWise® Architecture Council (GWAC) began to build a community of practice in the area of transactive energy systems. Starting with a workshop on the topic of “transactive energy” in May 2011, the Council brought together about a dozen interested researchers and practitioners from utilities, vendors, labs and academia to compare their approaches and experience in order to create common definitions and understanding within this topical area. This was followed in March 2012 with a second workshop during which about twice as many attendees continued the discussion. At this workshop the need for both a roadmap and a document documenting the foundations of transactive energy, common vocabulary and other definitional aspects was recognized. These two workshops led to the Council organizing the First International Conference and Workshop on Transactive Energy which took place May 23 – 24, 2013 in Portland, Oregon. The Council has continued this work with additional topical workshops, the Second International Conference and Workshop on Transactive Energy held in December 2014, and is currently organizing the Third International Conference and Workshop on Transactive Energy Systems to be held in May 2016. This article provides a summary of the Council’s work to build the community of practice through creation of a Transactive Energy Framework document and related activities. In addition to seeing

Transactional distance in a blended learning environment

Directory of Open Access Journals (Sweden)

Jon Dron

2004-12-01

Full Text Available This paper presents a case study that describes and discusses the problems encountered during the design and implementation of a blended learning course, largely taught online through a web-based learning environment. Based on Moore's theory of transactional distance, the course was explicitly designed to have dialogue at its heart. However, the reality of systemic behaviours caused by delivering such a course within a group of conventional further and higher educational institutions has led to an entirely unanticipated reversion to structure, with unpleasant consequences for both quality and quantity of dialogue. The paper looks at some of the reasons for this drift, and suggests that some of the disappointing results (in particular in terms of the quality of the students' experience and associated poor retention can be attributed to the lack of dialogue, and consequent increase in transactional distance. It concludes with a description and evaluation of steps currently being taken to correct this behaviour.

Growth Optimal Portfolio Selection Under Proportional Transaction Costs with Obligatory Diversification

International Nuclear Information System (INIS)

Duncan, T.; Pasik Duncan, B.; Stettner, L.

2011-01-01

A continuous time long run growth optimal or optimal logarithmic utility portfolio with proportional transaction costs consisting of a fixed proportional cost and a cost proportional to the volume of transaction is considered. The asset prices are modeled as exponent of diffusion with jumps whose parameters depend on a finite state Markov process of economic factors. An obligatory portfolio diversification is introduced, accordingly to which it is required to invest at least a fixed small portion of our wealth in each asset.

The impact of transaction trust on consumers' intentions to adopt m-commerce: a cross-cultural investigation.

Science.gov (United States)

Kao, Danny Tengti

2009-04-01

Mobile commerce (M-commerce) has been acknowledged as one of the most representative transaction types driving e-commerce worldwide; however, the potential security threats that keep consumers from M-commerce still confound the M-commerce industry. This research attempts to explore two questions: What are the dimensions of transaction trust that may significantly affect consumers' intentions to adopt M-commerce, and what are the cultural dimensions that may significantly moderate the impact of transaction trust on consumers' intentions to adopt M-commerce? A research framework based on the BATE model and Hofstede's cultural dimensions was established to identify how transaction trust and cultural value affect consumers' intentions to adopt M-commerce. Results revealed that transaction trust significantly affects consumers' intentions to adopt M-commerce. However, while uncertainty avoidance moderates the impacts of business trust and security on consumers' intentions of M-commerce adoption, both individualism/collectivism and long-term/short-term orientation moderate the relationship between security trust and consumers' intentions of M-commerce adoption.
