The delivery of IS services is very resource consuming in all organizations. In an era in which management optimization is one of the bases for competitive advantage, sourcing options must be judged carefully. Traditionally, the dilemma has been considered in terms of make (insourcing) or buy (outsourcing). But both of these options have shown a certain amount of problems. Although outsourcing ...

This paper presents intermediate results from a study of issues which influence shaping of information systems development (ISD) practices in systems and software development organizations. In line with previous research, the target organizations of our study tend to create local development practices by picking individual practices from (possibly different) methods combined with emergent pract...

For today's business organizations, workflow models play important roles in analyzing the productivity, evaluating the performances and costs, optimizing the business operations, and supporting evolving services and products. Workflow mining, the process of empirically extracting structured process descriptions from a set of real executions, thus has attracted a lot of attention recently. Howev...

Leaders play crucial roles in their enterprises. Most modern organizations today, such as corporations and government departments, have no leaders. About 80% of all top structures, are run by inertia leaderless organizations. These pretense-pseudo structures filled roles, CEO, Department Head/Secretary, EVP, VP, others, but this non-accountable system mostly harms than benefits the organization...

  The present study is an attempt towards remodeling cost, revenue and profit relationship within the network process. The previous models of Data Envelopment Analysis (DEA) have been too general in their scope and focused on the input and the output within a black box system, therefore they have not been able to measure various phases simultaneously within a network system. By using these mod...

This paper investigates how hospital affiliation in a multi-hospital system (contract managed, owned, sponsored), the number of system hospitals, HMO and PPO contracts, and other factors, impacts hospital cost efficiency. Using a 1996-1999 panel of 248 hospitals, results show that for urban hospitals, increasing the number of hospitals in the system, system ownership and contract management/spo...

in current work a comprehensive mechanism based on intermediate radical termination theory is assumed for raft polymerization of styrene over cumyl dithiobenzoate as raft agent. rate constants for addition (ka) and fragmentation reactions (kf) are set to 6×106 and 5×104 respectively, which lead to an equilibrium constant value of k = ka/kf = 1.2 x 102. moment equations method was used to model ...

background: xmn-1 polymorphism of y g globin gene ( hbg2 ) is a prominent quantitative trait loci (qtl) in β-thalassemia intermediate (β-ti). in current study, we evaluated frequency of xmn-1 polymorphism and its association with β-globin gene ( hbb ) alleles and hb f level in β-ti patients in sistan and balouchestan province, south-east of iran. methods: 45 β-ti patients were enrolled. hbb gen...
