This explorative study examines customer-supplier relationships from the perspective of psychological contracts. Based on findings from a multiple case study, the content of the psychological contracts of individuals involved in customer-supplier relationships are presented. The study provides support for the use of psychological contracts for describing the dynamics of customer-supplier relati...

This paper critiques blockchain-based “smart contracts,” which aim to automatically and securely execute obligations without reliance on a centralized enforcement authority. Though smart contracts do have some features that might serve the goals of social justice and fairness, I suggest that they are based on a thin conception of what law does, and how it does it. Smart contracts focus on the t...

We present a parametric calculus for contract-based computing in distributed systems. By abstracting from the actual contract language, our calculus generalises both the contracts-as-processes and contracts-as-formulae paradigms. The calculus features primitives for advertising contracts, for reaching agreements, and for querying the fulfilment of contracts. Coordination among principals happen...

his study aimed to investigate factors affecting the revenue share of Iranian tomato paste exporting companies. Flexible estimation method was used on a two-dimensional panel data set including 224 observations from 14 tomato paste manufacturing and exporting companies and 16 importing countries during 2005-12. Results showed that value added per employee in manufacturing or exporting companies...

The STD experiments in Guatemala from 1946-1948 have earned a place of infamy in the history of medical ethics. But if the Guatemala STD experiments were so "ethically impossible," how did the U.S. government approve their funding? Although much of the literature has targeted the failings of Dr. John Cutler, we focus on the institutional context and research ethos that shaped the outcome of the...

Systematic, well-designed research provides the most effective approach to the solution of many problems facing highway administrators and engineers. Often, highway problems are of local interest and can best be studied by highway departments individually or in cooperation with their state universities and others. However, the accelerating growth of highway transportation develops increasingly ...

This paper presents an approach for the specification and implementation of business contracts needed for Business-to-Business (B2B) services. We first examine typical elements of business contracts and their usage. This analysis sets a foundation for 1) modeling contracts and 2) developing a role-based architecture that supports typical operations in the contract’s lifetime. We explore how con...

0 1 5 Frequency [GHz] 6 2 3 4 Abstract The validity of lumped element microwave class-F amplifier circuit design has been demonstrated experimentally. By means of the proposed class-F amplifier design method, more than 4th-order higher harmonic frequencies can be taken into account in class-F microwave amplifier design using only lumped element components. In this approach, miniaturization of c...

The emerging service-dominant logic requires cooperation between several partners in a value-added network or value chain. Information asymmetry and information gaps may lead to uncovered and unused knowledge. This paper addresses how this problem can be solved by suggesting an approach based on contingency theory. The core idea consists of supporting and improving value-added partnerships by e...

In this paper, Black Scholes’s pricing model was developed to study American option on future contracts of Brent oil. The practical tests of the model show that market priced option contracts as future contracts less than what model did, which mostly represent option contracts with price rather than without price. Moreover, it suggests call option rather than put option. Using t hypothesis test...
