Modeling e-Negotiation Processes for a Service Oriented Architecture

Most of today's e-marketplaces support a single negotiation protocol. The protocol is usually built into the e-marketplace infrastructure, therefore if a new one is introduced then a time consuming and complex process of implementing it takes place. Moreover, participants in the e-marketplace need to adapt their interfaces to the new protocol, especially if they use automated tools to interact with the e-marketplace. This paper reports on a model-driven approach and a framework for rapid and user-friendly development of configurable service oriented e-negotiation systems. We believe that a formal specification of negotiation protocols and their separation from the market infrastructure that implements them is a step towards configurable e-negotiation systems. The protocols are graphically designed for the e-marketplace then mapped into web service orchestrations. Participants use automated negotiation systems to interact with the e-marketplace. These systems are generated based on the negotiation protocol implemented on the e-marketplace. A declarative language is used to specify negotiation strategies and tactics. We propose an algorithm to map Statechart models of negotiation protocols into web service orchestrations and we report on the current implementation of our framework.     

ARE PROJECT FINANCE LOANS DIFFERENT FROM OTHER SYNDICATED CREDITS?

This paper provides the first full-length empirical analysis of project finance, which is defined as "limited or non-recourse financing of a newly to be developed project through the establishment of a vehicle company." The article compares the characteristics of a sample of 4,956 project finance loans (worth $634 billion) to comparable samples of non-project finance loans, all of which are drawn from a comprehensive sample of 90,784 syndicated loans (worth $13.2 trillion) booked on international capital markets since 1980.
The authors find that project finance (PF) loans differ significantly from non-project finance loans in that PF loans have a longer average maturity, are more likely to have third-party guarantees, and are far more likely to be extended to non-U.S. borrowers and to borrowers in riskier countries. Project finance credits also involve more participating banks, have fewer loan covenants, are more likely to use fixed-rate rather than floating-rate loan pricing, and are more likely to be extended to borrowers in tangible-asset-rich industries, such as real estate and electric utilities. Despite being nonrecourse finance, floating-rate project finance loans have lower credit spreads (over LIBOR) than do most comparable non-PF loans. The authors also report that projects funded with PF loans are heavily leveraged, with an average loan to value ratio of 67%.

Increasing Effectiveness in Teaching Ethics to Undergraduate Business Students

Undergraduate business students present special needs and challenges in respect to the teaching of ethics. Traditional methods of teaching this topic are the subject of criticism in the literature. This paper considers the nature of the target audience while advancing the complementary goals of convincing undergraduate business students that ethical behavior in business is important and increasing the likelihood that these students will make ethical choices in the future. Shortcomings of approaches commonly used to teach this topic are discussed. Specific instructional techniques to supplement or replace traditional pedagogy are suggested.     

Arzthaftung bei Überschreiten der gesetzlichen Arbeitszeit

The essay deals with the adhesion of the hospital carrier and physician regarding work time offences and an overtire-conditioned medical malpractice. Due to the valuation and statement of the work time law the work efficiency of an employee is to be asked for the border. The employment overtired physicians is then as adhesion for an incorrect organization to be stated ’ also in the light of cost scarceness and shortage of personnel. The question about the personal responsibility of the false treating and overtired physician is answered. Here is to be particularly considered the dependence of the physician on the roster organization and its specific employee protection by the work time law. The consequences for the physician adhesion process and in particular for the burden of proof are to be examined then. In the center it is located here whether the overtire-conditioned damage of the patient represents a rough treatment error because such a rough treatment error justifies the reversal of the burden of proof for causality. Finally the influence of the work time offence is examined in connection with the damage of the patient for the liability insurance protection.     

Climate change and trade in agriculture

Agricultural productivity in both developing and developed countries will have to improve to achieve substantial increases in food production by 2050 while land and water resources become less abundant and the effects of climate change introduce much uncertainty. Already less resilient production areas will suffer the most, as temperatures will rise further in tropical and semi-tropical latitudes and water-scarce regions will face even drier conditions. International trade plays an important role in compensating, albeit partially, for regional changes in productivity that are induced by climate change. While a well-functioning international trade system can support the adaptation to climate change-related challenges, trade policies as such are imperfect instruments to induce less emissions globally. A well-functioning international trading system can support the adaptation to climate change-related challenges. Hence welfare gains from reforms to trade policies may be greater than normally measured if they also reduce GHG emissions globally.
