. In essence, eigenvector centrality is a recursive measure of degree, whereby the centrality of an actor is defined as the sum of his ties to other actors, weighted by their respective centralities. Formally, let p ij be an indicator equaling one if at least one syndication relationship exists between VC i

Differential testing, a form of random testing, is a component of a mature testing technology for large software systems. It complements regression testing based on commercial test suites and tests locally developed during product development and deployment. Differential testing requires that two

to have seven scores (out of a possible 12) of 1 to be identified as low reactive. Of the 225 infants screened in the second cohort, 27 were classified as High Negative, 23 as High Positive, and 22 as Low Reactive. Consistent with the selection criteria, these three groups differed significantly on each

Transactional Memory (TM) promises to simplify concurrent programming, which has been notoriously difficult but crucial in realizing the performance benefit of multi-core processors. Software Transaction Memory (STM), in particular, represents a body of important TM technologies since it provides a

with respect to the boundary between programming languages and other forms of software: Scripting languages? Spreadsheets? Macro languages? Keyboard macros? Configuration files? Java programs? Javascript programs? Server Side Include macros? Cascading Style Sheets? HTML pages? Microsoft Word documents? From

Abstract This paper examines the problem of statically analyzing the performance of embedded software. This problem is motivated by the increasing growth of embedded systems and a lack of appropriate analysis tools. We study dierent performance metrics that need to be considered in this context

This article focuses on the sociopolitical aspects of implementing open source software (OSS) in schools. Supporters of such implementation make a compelling case for OSS based on the clear advantages it offers over commercial applications—advantages such as its low cost, its freedom from

Software fault injection is a process that discovers how "badly" software can behave after its state gets corrupted. Fault injection results are sometimes viewed suspiciously since state corruption is hypothetically-based. In response to this suspicion, this paper explores the potential

perfection. Meanwhile, a new generation of developers cites the crushing weight of corporate bureaucracy, the rapid pace of information technology change, and the dehumanizing effects of detailed plan-driven development as cause for revolution. In their rallying cry, the Manifesto for Agile Software
