There exist various service systems that have hierarchical structure. In hierarchical service networks, facilities at different levels provide different types of services. For example, in health care systems, general centers provide low-level services such as primary health care services, while the specialized hospitals provide high-level services. Because of demand congestion in service networ...

In this article, we propose a new methodology for solving the vendor selection and the supply quotas determination problem. The proposed methodology combines the Analytic Hierarchy Process (AHP) for determining the coefficients of the objective functions and a new multiple objective programming method based on the cooperative game theory for vendor selection and supply quotas determination. The...

We present an update of results from the HPQCD collaboration on charm physics using the Highly Improved Staggered Quark action. This includes a precise determination of mc using moments of current-current correlators combined with high-order continuum QCD perturbation theory. We also include an update on the determination of αs from lattice QCD, preliminary results on the determination of mb an...

This paper examines the use of incentive pay schemes within the financial services sector in London. Various theories of wage determination are reviewed with particular attention placed on the principal-agent literature as a framework for analysing the use of incentive pay. This is combined with case study interviews and a number of hypotheses regarding the use of bonuses. Quantitative analysis...

This paper discusses the analysis techniques used to derive the excitation waveform for multipulse coding of speech. A computationally efficient formulation is derived for both covariance and correlation type analyses. These methods differ in the way block edges are treated. Several methods for pulse amplitude and posihiou determination are given, ranging from a purely sequential one to one whi...

The agreement of electroweak measurements with theory places limits on the masses of the top quark and the W boson. It is shown how these limits arise and what constraints various measurements (particularly a top quark mass determination) would provide on the theory. The degree to which present and future measurements can constrain the Higgs boson mass is examined.

Self-determination theory is one of the most established motivational theories both within second language learning and beyond. This has generated several mini-theories, namely: organismic integration theory, cognitive evaluation basic psychological needs goal contents causality orientations relationships motivation theory. After providing an up-to-date account these we present results a system...

The fiscal theory of price determination asserts that the price level is determined by the ratio of nominal public debt to the present value of real primary surpluses. To show its fragility, we describe a cash-in-advance economy with infinitely lived real productive assets. The fiscal theory does not hold since speculative bubbles partly restore the classical indeterminacy result.
