Stock prices and top management changes
- Journal of Financial Economics
, 1988
"... This p~er studies the association between a finn's stock returns and subsequent top management chAMes. Con~ieut w~th mmml monitoring of management, there is an inverse relation between the probability of a management change and a firm's share performance. ~ relation can result from monitor ..."

between a firm's stock price perfor-mance and subsequent changes in its top management. A top management change is defined as any change in the set of individuals holding the title of chief executive officer (CEO), president, or chairman of the board. The major hypothesis is that the probability of a
Understanding sources of inefficiency in general-purpose chips
- IN ISCA ’10: PROCEEDINGS OF THE 37TH ANNUAL INTERNATIONAL SYMPOSIUMONCOMPUTERARCHITECTURE,TOAPPEAR(2010),IEEEPRESS
"... Due to their high volume, general-purpose processors, and now chip multiprocessors (CMPs), are much more cost effective than ASICs, but lag significantly in terms of performance and energy efficiency. This paper explores the sources of these performance and energy overheads in general-purpose proces ..."

Addressing the ZooKeeper Synchronization Inefficiency
"... Abstract. In this paper we discuss the problem of synchronization in ZooKeeper, a fault-tolerant distributed coordination framework. One of the key features of ZooKeeper is to move away from blocking API such as locks, in order to avoid problems with slow or faulty clients. Instead, it provides an e ..."

an event like synchronization mechanism, allowing clients to be notified upon state change on the server. However, such a mechanism leads to very inefficient implementation of synchronization objects such as queues or barriers. We propose a new solution to this problem. The solution is to handle a sequence
Detecting Inefficiently-Used Containers to Avoid Bloat
- ACM SIGPLAN 2010 CONFERENCE ON PROGRAMMING LANGUAGE DESIGN AND IMPLEMENTATION
, 2010
"... Runtime bloat degrades significantly the performance and scalability of software systems. An important source of bloat is the inefficient use of containers. It is expensive to create inefficiently-used containers and to invoke their associated methods, as this may ultimately execute large volumes of ..."

Extending Graphplan to Handle Uncertainty & Sensing Actions
- In 5th European Conference on Planning (ECP’99) (Springer-Verlag
, 1999
"... If an agent does not have complete information about the world-state, it must reason about alternative possible states of the world and consider whether any of its actions can reduce the uncertainty. Agents controlled by a contingent planner seek to generate a robust plan, that accounts for and hand ..."

for and handles all eventualities, in advance of execution. Thus a contingent plan may include sensing actions which gather information that is later used to select between different plan branches. Unfortunately, previous contingent planners suffered defects such as confused semantics, incompleteness
Decentralizing execution of composite web services
- In OOPSLA ’04: Proceedings of the 19th annual ACM SIGPLAN conference on Object-oriented programming, systems, languages, and applications
, 2004
"... Distributed enterprise applications today are increasingly being built from services available over the web. A unit of functionality in this framework is a web service, a software application that exposes a set of “typed ” connections that can be accessed over the web using standard protocols. These ..."

Metric: Memory tracing via dynamic binary rewriting to identify cache inefficiencies
- ACM Transactions on Programming Languages and Systems
, 2007
"... With the diverging improvements in CPU speeds and memory access latencies, detecting and removing memory access bottlenecks becomes increasingly important. In this work we present METRIC, a software framework for isolating and understanding such bottlenecks using partial access traces. METRIC extrac ..."

Executive Summary

The health care delivery system in the United States despite being one of the most technologically advanced in the world, still fails to provide evidence-based preventive services and therapies that have been shown to decrease morbidity and mortality in almost half of all patient visits. At the same ..."
Abstract

. At the same time that quality deficiencies are being noted, the cost of providing health care in the United States continues to rise at a rate exceeding general inflation or growth in the GDP. Inefficiencies are apparent through over-utilization of expensive and unnecessary procedures, the system‟s focus
