This paper develops an economic theory of the costs and benefits of corporate culture – in the sense of shared beliefs and values – in order to study the effects of ‘culture clash’ in mergers and acquisitions. I first use a simple analytical framework to show that shared beliefs lead to more delegation, less monitoring, higher utility (or satisfaction), higher execution effort (or motivation), ...

Secure keyword search in shared infrastructures prevents stored documents from leaking sensitive information to unauthorized users. A shared index provides confidentiality if it is exclusively used by users authorized to search all the indexed documents. We introduce the Lethe indexing workflow to improve query and update efficiency in secure keyword search. The Lethe workflow clusters together...

conclusions accidents resulting in death, total disability, and partial disability impose a huge cost burden on society, whereas the employer will bear a relatively low cost. this is because of society’s health, treatment, and welfare systems available for treatment and rehabilitation of injured employees and their families. background occupational accidents represent one of the major problems ...

Shared service centers have become one of the most discussed models and been widely diffused by companies. It helps to reduce costs standardize operational processes, bringing more efficiency. But there is still a dilemma under its performance, gain in processes centralization especially when compared outsourcing services. The intention this article demonstrate various perceptions model, compar...

In a competitive environment, companies continuously innovate to offer superior services at lower costs. ‘Shared Services’ have been extensively adopted in practice as a means for improving organizational performance. Shared Services are considered most appropriate for support functions and are widely adopted in human resource management, finance and accounting, and more recently employed as an...

Networked computer systems offer much to support collaborative editing of shared documents among users. Software Engineering is one of many fields that benefits from computer-assisted collaboration as a myriad of developers, project managers, testers, and designers work together to develop large, complex systems that consist of a multitude of process and product artifacts. Multi-discipline and ...

Shared-disk parallel database systems are one form to exploit parallel architectures for high performance transaction processing. A shared-disk parallel database consists of several processing nodes that are loosely coupled via a communication network and share the common database at the disk level. This thesis provides a comprehensive performance study of shared-disk systems. We have developed...

In the absence of a perfect risk adjustment scheme, cost sharing can reduce risk selection in community-rated health insurance markets. However, cost sharing also reduces incentives for efficiency. In this paper, we develop a model in which insurers determine the cost efficiency of health care. They have incentives for risk selection because there are two risk types which differ in their expect...

Secure group communication is important for applications such as pay-per-view. Other authors have proposed the key tree approach to distribute a shared group key in a way such that the rekeying cost scales linearly with the logarithm of the group size for a join or depart request. The efficiency of the key tree approach depends critically on whether the key tree remains balanced. Periodic rebal...
