The study of highly unstable nonlinear dynamical systems—chaotic systems—has emerged recently as an area of major interest and applicability across the mathematical, physical and social sciences. This interest has been triggered by advances in the past decade, particularly in the mathematical understanding of complex systems. An important insight that has become widely recognized in recent years is that deterministic systems can give rise to chaotic behavior. Surprisingly, many of these systems are extremely simple, yet they exhibit complex chaotic behavior.
Computer modeling is radically redefining healthcare and epidemiology by providing new tools for understanding the impact of different intervention strategies.
As computer technologies increasingly invade everyday products, the risks of the traditional computer business must be revisited by each new industry, usually through failures. Issues include reliability of code, protection against component failure, security of data, privacy and security, safety, maintenance, and upkeep. There is one issue affecting all of these topics: ease of use. […]
While I largely agree with Sarah Spiekermann's "The Challenges of Privacy by Design" (July 2012), I want to make it clear that many organizations do understand the need to embed privacy in their systems and technologies and regularly ask my office's help in doing so.
In the wake of September 11th, the concept of a national identity (NID) card system has been getting considerable play, largely promoted by persons who might gain financially or politically from its implementation, or by individuals who simply do not understand the complex implications of such a plan. Authentic unique identifiers do have some potentially […]
Many of these monthly missives have addressed the different ways ACM is working to change the image of computing professionals. This month, in the spirit of April Fool's Day, we root out the ACM President's effort to change that image one person at a time---starting at the top.
Computing is central to the debate about so many aspects of our present and future that we have a duty and responsibility to be active and enthusiastic participants. By paying it forward (serial reciprocity), we create an environment where a new generation can thrive, just as the founders of the field did for us.
To ensure the timely publication of articles, Communications created the Virtual Extension which brings readers high-quality articles in an online-only format. The following articles are now available in their entirety to ACM members via the Digital Library.
How does replication of experiments and systems move HCI research forward? Wouldn't replication simply waste valuable researcher energy that might be better spent on actually creating new novel ideas or systems? This essay argues that replication is more than just duplication of work, but instead is an essential step in scientific explorations.
Communications created the Virtual Extension (VE) to expand the page limitations of the print edition by bringing readers the same high-quality articles in an online-only format. VE articles are available in their entirety to ACM members via the Digital Library.
To ensure the timely publication of articles, Communications created the Virtual Extension (VE) to expand the page limitations of the print edition by bringing readers the same high-quality articles in an online-only format. VE articles undergo the same rigorous review process as those in the print edition and are accepted for publication on merit. The following synopses are from articles now available in their entirety to ACM members via the Digital Library.
Communications of the ACM (CACM) is now a fully Open Access publication.
By opening CACM to the world, we hope to increase engagement among the broader computer science community and encourage non-members to discover the rich resources ACM has to offer.
