Flaws due to race conditions in which the binding of a name to an object changes between repeated references occur in many programs. We examine one type of this flaw in the UNIX operating system, and describe a semantic method for detecting possible instances of this problem. We present the results of one such analysis in which a previously undiscovered race condition flaw was found.

In this paper we show that data races, a type of bug that generally only causes havoc in parallel programs, can also occur in sequential programs that use signal handlers. Fortunately, it turns out that adapting existing data race detectors to detect such bugs for sequential programs is straightforward. We present such a tool, and we describe the modifications that were necessary to detect data...

However, despite the enormous potential presented by this remarkable data source, we still do not have an understanding of the Twitter population itself: Who are the Twitter users? How representative of the overall population are they? In this paper, we ...

Studies examining the impact of relevant factors on Africa’s regions’ capabilities to e...

This study advances research on the return from entrepreneurial orientation by examining how a firm’s internal system (i.e.,SHRM) and the external environment (i.e., technical turbulence) within which a firm operates intervene in the relationship between entrepreneurial orientation and product innovation performance. This study finds that entrepreneurial orientation is positively related to pro...
