Can the modern economy function without a market for interestbased credit? This question has acquired some urgency in the wake of the recent Shariat Court ruling banning interest in Pakistan. Some pundits have pronounced that great harm will result from the banning of interest. Actually, such pronouncements are based on a lack of understanding of both the modern economic system, as well as the ...

The supplier selection and order allocation are two key strategic decisions in purchasing problem. The review presented in this paper focuses on the supplier selection problems (SSP) and order allocation from year 2000 to 2017 in which a new structure and classification of the existing research streams and the different MCDM methods and mathematical models used for SSP will be presented. The re...

BACKGROUND Clinician-parent interaction and health system influences on parental acceptance of prescribing decisions for children with respiratory tract infections (RTIs) may be important determinants of antibiotic use. OBJECTIVE To achieve a deeper understanding of parents' acceptance, or otherwise, of clinicians' antibiotic prescribing decisions for children with RTIs. METHODS Qualitative...

in today’s turbulent world, the continuity of criticalactivities in the event of disruptions, and also fast recovery and return tobusiness as usual, are vital for sustainable success of companies. maintainingcontinuous delivery of critical business processes in the event of disruptions isa matter of business continuity. business continuity management system (bcms)is concerned with the developme...

A well-known model of nonstandard analysis is obtained by extending the structure of real numbers using an ultra power construction. A constructive approach due to Schmieden and Laugwitz uses instead a reduced power construction modulo a cofinite filter, but has the drawback that the transfer principle is weak. In this paper it is shown that this principle can be strengthened by employing Brouw...

We study two boundaries for the Teichmüller space of a surface Teich(S) due to Bers and Thurston. Each point in Bers’ boundary is a hyperbolic 3-manifold with an associated geodesic lamination on S, its endinvariant, while each point in Thurston’s is a measured geodesic lamination, up to scale. We show that when dimC(Teich(S)) > 1 the end-invariant is not a continuous map to Thurston’s boundary...

A [semi-]continuous real function of a frame (locale) L has up to now been understood as a frame homomorphism from the frame L(R) of reals into L [as a frame homomorphism (modulo some conditions) from certain subframes of L(R) into L]. Thus, these continuities involve different domains. It would be desirable if all these continuities were to have L(R) as a common domain. This paper demonstrates...

We show that principles from nonstandard analysis hold to some extent for nonlinear generalized functions. The generalized functions under consideration are constructed as families of functions modulo a free filter, as it is usually done in applied analysis. In contrast with models of nonstandard analysis, we do not require the filter to be an ultrafilter. The principles are intended to be used...
