Background: The study examined the impact of a contract farming scheme on the farmers’ income, food security, and nutrition. Methods: Simple random sampling was used to select 100 respondents for the study. Data were analyzed using descriptive and inferential statistics as well the Propensity Score Matching technique. Results: The major determinants of participation in contract farming included...

This study proposes a novel option-revenue sharing coordination contract framework. In the proposed model, the retailer determines the number of order sales effort. The manufacturer sets the price of products for the wholesale strategy. The investigated supply chain problem analyzes the results of different strategies. In the proposed coordination contract problem, two types of games including ...

We describe an approach to the specification, analysis and verification of AADL models using assume/guarantee behavioural contracts specified with the Property Specification Language (PSL). This approach aids the development process by 1) supporting the reuse and replacement of components based on their contracts rather than only their interface or their implementation and thus reducing the nee...

a contractual relationship is commonly based on statements, expectations, acts and omissions out of which some will, and others will not, give rise to contractual obligations. to avoid uncertainty as to what is agreed, the contract parties often enter into a written contract that is supposed to express the final agreement between them and prevent the parties from relying on rights and obligatio...

when the parties enter into a contract, they are obliged to implement its obligations, but sometimes events occur that make it impossible to execute the contract or runtime status than the time of conclusion of the contract is fundamentally different. these events are referred to as legal excuses if eligible, the parties are exempt from the obligations and responsibilities. the most important l...

To control quality in supply chain, this paper presents multi-period, dynamic game models in principal-agent theory, which are opposite to static, single period game models. The research comes from industrial practice and the conclusions are more operational and feasible in theory. Finally, the research is applied into two famous companies in different industries and shows good effectiveness. m...

The dynamical origin of the CP violation in electroweak theory is investigated in composite Higgs models. The mechanism of the spontaneous CP violation proposed in other context by Dashen is adopted to construct simple models of the dynamical CP violation. Within the models the size of the neutron electric dipole moment is estimated and the constraint on the ε-parameter in K-meson decays is dis...

the study of rights of obligee in any commercial contract, particularly contract of sale, is very important for the theoretical and practical reasons, in case that the other party performs part of contract only and is not able or ready to perform the other part; because, on the one hand, the obligor wants to know whether he entitles to expect from the obligee to accept the executed part of cont...
