Most performance evaluation models in operations management literature have assumed that tasks possess standardized completion criteria. However, in many operation systems, particularly in service and professional work, judgment is frequently required to determine when a task is completed. In thin paper, we show that introducing discretion in task completion adds a fourth variability buffer, qu...

Abstract Built on the exclusive funding of 1,000 large transnational corporations, World Economic Forum is a not-for-profit Swiss foundation, aiming to shape direction globalization. Its events are characterized by low degrees formality and transparency. Research what this organization does scarce. This article suggests term discretionary governance capture precarious, yet existing, social orde...

This paper studies bounded-velocity control of a Brownian motion when discretionary stopping, or ‘leaving’, is allowed. The goal is to choose a control law and a stopping time in order to minimize the expected sum of a running and a termination cost, when both costs increase as a function of distance from the origin. There are two versions of this problem: the fully-observed case, in which the ...

The number one function of governments anywhere in the world is to achieve public interest. Public interest and social interactions are so vast, complex dynamic that; a government can not effectively administer all aspects by itself. Plainly put, whenever citizens require or request for service from government, it an implicit set up institution discharge provision that service. Owing this, inst...

Tripunitara, Mahesh V. Ph.D., Purdue University, December, 2005. A Theory Based on Security Analysis for Comparing the Expressive Power of Access Control Models. Major Professor: Ninghui Li. We present a theory for comparing the expressive power of access control models. Our theory is based on reductions that preserve the results of security analysis. Security analysis is an approach to the ver...

BACKGROUND Sunscreen use and dietary antioxidants are advocated as preventives of skin aging, but supporting evidence is lacking. OBJECTIVE To determine whether regular use of sunscreen compared with discretionary use or β-carotene supplements compared with placebo retard skin aging, measured by degree of photoaging. DESIGN Randomized, controlled, community-based intervention. (Australian N...

Motivated by the findings that the aggregate (discretionary) accruals positively predicts oneyear-ahead firm-level stock returns and that there is a considerable amount of co-movement in firm-level (discretionary) accruals, we decompose firm-level (discretionary) accruals into a market-wide component and a firm-specific component. We document robust evidence that the two orthogonal (discretiona...

The paper analyses the existence and efficiency of discretionary industrial assistance schemes under asymmetric information between an uninformed government and a uniform distribution of firms with differing productivities. Discretionary assistance allows the government to scrutinise projects in an effort to learn the type, which can reduce the ‘informational rents’ of automatic assistance, whe...
