To this end, it must be ascertained whether electrical energy is bought/sold for an industrial use exclusively, so that the relevant transaction will be accounted as a normal purchase/sale, or through the lease of the relevant production plant, which would require the supply contract to be accounted in compliance with International Accounting Standards (IAS) 17 "Leasing". Alternatively, it must also be ascertained whether the relevant party is implementing financial trading strategies, as in such hypothesis, the supply contract is to be accounted as a financial instrument according to International Financial Reporting Standards (IFRS) 9/IAS 39 "Financial Instruments". Finally, the modalities used by a number of companies listed on European regulated markets to account such kind of contracts will be analyzed.展开更多

Previous studies highlight negative effect of these agreements stressing particularly on losses in government revenues due to the removal of all tariffs on imports. This analysis aims to provide some insight into this question by refreshing the debate to show how this situation could be transformed into opportunities for Ivory Coast in order to promote growth and reduce poverty. To do so, this study postulates that government spending (investment) in economic infrastructure (roads, bridges, communication network, etc.), in education and health sectors produces positive externalities in each industry. This assumption has not been set anymore in previous studies. Simulation results reveal that, despite this decline in government revenues, if it invests in economic infrastructure, health and education sector, EPAs will generate more revenue for government due to the rise in income tax on firms and households, and tax on overall production. Furthermore, household income will increase which will in turn stimulate (final) consumption. There won't also be a decline in economic growth.展开更多

Several issues and conflicts exist in the negotiation of cloud agreement terms due to the legal and ambiguous terms in Service Level Agreements (SLA). Semantic knowledge applied during the formation and negotiation of SLA can overcome these issues. Cloud SLA negotiation consists of numerous activities such as formation of SLA templates, publishing it in registry, verification and validation of SLA, monitoring for violation, logging and reporting and termination. Though these activities are interleaved with each other, semantic synchronization is still lacking. To overcome this, a novel SLA life cycle using semantic knowledge to automate the cloud negotiation has been formulated. Semantic web platform using ontologies is designed, developed and evaluated. The resultant platform increases the task efficiency of the consumer and the provider during negotiation. Precision and recall scores for Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) SLAs were calculated. And it reveals that applying semantic knowledge helps the extraction of meaningful answers from the cloud actors.展开更多

A CA-EU AA content analysis within the broader EU policy approach towards Latin America suggests it to be (1) the only feasible option for each side at a time of increasing commercial flux; (2) mutually attractive against globalizing threats, thus converting an institutional innovation into a double-edged instrument; and (3) illustrative of the subtle but significant shift of farm-protection demands from endogenous dynamics to exogenous. They carry important implications: (1) empirically: weak CA-EU linkages further dilute West Europe's broader Latin ambitions; (2) theoretically: AA analyses better reflect trading realities than pure regional economic integration theories, suggesting the corrosive impact of globalizing forces on regional pursuits; and (3) historically: the continued role of the farm jinx in trade.展开更多

Hence, it is important to define the rights and responsibilities of the parties, and relationships among them. In this context, well-designed and complete agreement is essential and necessary for the successfully completion of a construction project within the desired time, quality and budget. In this paper, it is aimed to analyze and compare the owner-contractor agreements in the Turkish and the US construction industry. First, the importance of construction contracts and contractual elements of an agreement is determined, and then, the standard owner-contractor agreement which is used in the Turkish construction industry is analyzed and compared with the US standard owner-contractor agreement. Finally, the differences between these agreements are put forward, the lack and deficiencies of Turkish standard agreement form are determined, and appropriate suggestions are improved.展开更多

One of the various facets concerning the availability of class arbitration has gathered overwhelming discussion in the US. According to the decisions of the United States Supreme Court, whether class action is applicable is probably decided by the arbitrator's interpretation of the parties' intent when an adequately drafted arbitration clause is silent on this issue, regardless of the correctness of his/her construing of the contracts. The contract interpretation theory is a conclusion of existing jurisprudence while the question of arbitrability doctrine may be a hint or inkling from a recent court decision. Comparing these two sides, it is better to regard the availability of class arbitration for silent agreements as a matter of contract interpretation. Although it is preferable to regard the availability issue of class action as a contract interpretation question, some restrictions on the arbitrators' broad contract interpretation needs to be imposed so that the parties' real intent can be properly enforced.展开更多

In clinical investigations, Bland and Altman proposed plotting subject-wise differences between raters against subject-wise averages. In order to scientifically assess agreement, Bartko recommended combining the graphical approach with the statistical analytic procedure suggested by Bradley and Blackwood. The advantage of using this approach is that it enables significance testing and sample size estimation. We noted that the direct use of the results of the regression is misleading and we provide a correction in this regard. Methods: Graphical and linear models are used to assess agreements for continuous scale measurements. We demonstrate that software linear regression results should not be readily used and we provided correct analytic procedures. The degrees of freedom of the F-statistics are incorrectly reported, and we propose methods to overcome this problem by introducing the correct analytic form of the F statistic. Methods for sample size estimation using R-functions are also given. Results: We believe that the tutorial and the R-codes are useful tools for testing and estimating agreement between two rating protocols for continuous scale measurements. The interested reader may use the codes and apply them to their available data when the issue of agreement between two raters is the subject of interest.展开更多

Venturing beyond just the immediate repercussions, the research unearths both the overt and concealed long-term consequences that businesses encounter. This study integrates findings from various research, including quantitative reports, drawing upon real-world incidents faced by both small and large enterprises. This investigation emphasizes the profound intangible costs, such as trade name devaluation and potential damage to brand reputation, which can persist long after the breach. By collating insights from industry experts and a myriad of research, the study provides a comprehensive perspective on the profound, multi-dimensional impacts of cybersecurity incidents. The overarching aim is to underscore the often-underestimated scope and depth of these breaches, emphasizing the entire timeline post-incident and the urgent need for fortified preventative and reactive measures in the digital domain.展开更多

From the viewpoint of China, there are many potential gains from entering into free trade agreements (FTAs) with its neighbors, who collectively form a large and fast-growing market. In this paper, we qualitatively and quantitatively assess the four main permutations of China's FTAs with East Asian major economies: China-ASEAN, China-Japan, China-Korea and ASEAN+ 3. We compare the effects of these FTAs on China "s output and welfare. Our comparative analysis shows that China will gain from all three bilateral FTAs, while gaining the most from the ASEAN+ 3. Because forming a region-wide FTA, such as the ASEAN+ 3, is expected to be gradual and difficult, China shouM continue to engage in bilateral FTAs as a mediumterm and alternative strategy. However, in the long term, China should pursue a regionwide FTA.展开更多

The paper highlights the severity and discriminatory nature of China's anti-dumping problems. The high concentration of the share of anti-dumping actions taken by the top 4 and top 8 anti-dumping initiators is noted. Our finding of a weak effect of existing RTAs on mitigating China 's anti-dumping problems supports the argument that China could become more active in mitigating anti-dumping problems through RTA negotiations. An RTA can include a higher level of openness in exchange for an improvement in regional anti-dumping provisions. Case studies on RTAs involving the EU, the USA and India offer some precedents for offering inducements and modifying regional anti-dumping provisions. The approaches for China may lie in obtaining market economy status from intensive anti-dumping initiators at RTA levels and also altering regional anti-dumping provisions that could be put in place in exchange for some potential concessions.展开更多

We compare the effects of these FTAs on China "s output and welfare. Our comparative analysis shows that China will gain from all three bilateral FTAs, while gaining the most from the ASEAN+ 3. Because forming a region-wide FTA, such as the ASEAN+ 3, is expected to be gradual and difficult, China shouM continue to engage in bilateral FTAs as a mediumterm and alternative strategy. However, in the long term, China should pursue a regionwide FTA.
文摘The present paper explores the opportunities for China's regional trade agreement (RTA) initiatives to mitigate its anti-dumping problems. The paper highlights the severity and discriminatory nature of China's anti-dumping problems. The high concentration of the share of anti-dumping actions taken by the top 4 and top 8 anti-dumping initiators is noted. Our finding of a weak effect of existing RTAs on mitigating China 's anti-dumping problems supports the argument that China could become more active in mitigating anti-dumping problems through RTA negotiations. An RTA can include a higher level of openness in exchange for an improvement in regional anti-dumping provisions. Case studies on RTAs involving the EU, the USA and India offer some precedents for offering inducements and modifying regional anti-dumping provisions. The approaches for China may lie in obtaining market economy status from intensive anti-dumping initiators at RTA levels and also altering regional anti-dumping provisions that could be put in place in exchange for some potential concessions.
