The Ponder Policy Specification Language
- LECTURE NOTES IN COMPUTER SCIENCE
, 2001
"... The Ponder language provides a common means of specifying security policies that map onto various access control implementation mechanisms for firewalls, operating systems, databases and Java. It supports obligation policies that are event triggered conditionaction rules for policy based management ..."

These reusable composite policy specifications cater for the complexity of large enterprise information
An Overview of Workflow Management: From Process Modeling to Workflow Automation Infrastructure
- DISTRIBUTED AND PARALLEL DATABASES
, 1995
"... Today’s business enterprises must deal with global competition, reduce the cost of doing business, and rapidly develop new services and products. To address these requirements enterprises must constantly reconsider and optimize the way they do business and change their information systems and appl ..."

) workflow automation to generate workflow implementations from workflow specifications. This paper provides a high-level overview of the current workflow management methodologies and software products. In addition, we discuss the infrastructure technologies that can address the limitations of current
NeXt generation/dynamic spectrum access/cognitive Radio Wireless Networks: A Survey
- COMPUTER NETWORKS JOURNAL (ELSEVIER
, 2006
"... Today's wireless networks are characterized by a fixed spectrum assignment policy. However, a large portion of the assigned spectrum is used sporadically and geographical variations in the utilization of assigned spectrum ranges from 15% to 85% with a high variance in time. The limited availabl ..."

Motivation through the Design of Work: Test of a Theory. Organizational Behavior and Human Performance,
, 1976
"... A model is proposed that specifies the conditions under which individuals will become internally motivated to perform effectively on their jobs. The model focuses on the interaction among three classes of variables: (a) the psychological states of employees that must be present for internally motiv ..."

in the management literature, in fact little is known about the reasons why "enriched" work sometimes leads to positive outcomes for workers and for their employing organizations. Even less is known about the relative effectiveness of various strategies for carrying out the redesign of work One reason
A Resource Management Architecture for Metacomputing Systems
, 1997
"... Metacomputing systems are intended to support remote and/or concurrent use of geographically distributed computational resources. Resource management in such systems is complicated by five concerns that do not typically arise in other situations: site autonomy and heterogeneous substrates at the ..."

at the resources, and application requirements for policy extensibility, co-allocation, and online control. We describe a resource management architecture that addresses these concerns. This architecture distributes the resource management problem among distinct local manager, resource broker, and resource co
Matchmaking: Distributed Resource Management for High Throughput Computing
- In Proceedings of the Seventh IEEE International Symposium on High Performance Distributed Computing
, 1998
"... Conventional resource management systems use a system model to describe resources and a centralized scheduler to control their allocation. We argue that this paradigm does not adapt well to distributed systems, particularly those built to support high-throughput computing. Obstacles include heteroge ..."

A Fluid-based Analysis of a Network of AQM Routers Supporting TCP Flows with an Application to RED
- Proc. SIGCOMM 2000
, 2000
"... In this paper we use jump process driven Stochastic Differential Equations to model the interactions of a set of TCP flows and Active Queue Management routers in a network setting. We show how the SDEs can be transformed into a set of Ordinary Differential Equations which can be easily solved numeri ..."

Policy driven management of distributed systems
- Journal of Network and Systems Management
, 1994
"... Separating management policy from the automated managers which interpret the policy facilitates the dynamic change of behaviour of a distributed management system. This permits it to adapt to evolutionary changes in the system being managed and to new application requirements. Changing the behaviour ..."

the behaviour of automated managers can be achieved by changing the policy without have to reimplement them – this permits the reuse of the managers in different environments. It is also useful to have a clear specification of the policy applying to human managers in an enterprise. This paper describes the work
A Survey of Trust in Internet Applications
, 2000

MANAGING WITH STYLE: THE EFFECT OF MANAGERS ON FIRM POLICIES
, 2003
"... This paper investigates whether and how individual managers affect corporate behavior and performance. We construct a manager-firm matched panel data set which enables us to track the top managers across different firms over time. We find that manager fixed effects matter for a wide range of corpora ..."

We identify specific patterns in managerial decision making that appear to indicate general differences in “style” across
