What Matters When Introducing New Information Technology
Focusing on the right issues at the right time increases the likelihood of success.
Domain Expert User Development: the Smartgov Approach
The European Union's SmartGov project transforms public-sector employees into developers of the government e-services used directly by the public.
The Online Consumer’s Hierarchy of Needs
Web site designers take heed: Not all interface characteristics are created equal.
Sox, Compliance, and Power Relationships
There are several tactics CIOs can use for SOX compliance implementation. A pivotal one is understanding their relationship with the CEO, CFO, and auditors.
What’s Wrong with Online Privacy Policies?
Research has shown that privacy policies tend to intensify privacy concerns rather than engender trust. One way to combat this dichotomy is to redesign their content, language, and presentation format.
Parallel Computing on Any Desktop
Parallelization lets applications exploit the high throughput of new multicore processors, and the OpenMP parallel programming model helps developers create multithreaded applications.
Molecular, Chemical, and Organic Computing
Evaluating computation at the level of individual molecules.
Autonomous Programmable Biomolecular Devices Using Self-Assembled DNA Nanostructures
Surveying recent developments in bio-DNA computing.
Amoeba-Based Neurocomputing with Chaotic Dynamics
Implementing a deadlock-breaking neural computing scheme that can flexibly search for reasonable solutions without any resource allocation program.
The meaning and implementation of the term "computing" has changed greatly since ACM was first organized 60 years ago. This special section presents overview articles collectively called "non-silicon-based new computing paradigms." Although these paradigms often differ from one another significantly, there are three common characteristics: the techniques are not based on the traditional silicon-based integrated circuit technology; the basic computing elements have been physically implemented, meaning they are not just theory; and many of them aim at miniaturization, often on the order of 1--100 nanometers. Here, the term "computing" is employed in a very broad sense.
Toward a World with Quantum Computers
Surveying the recent past and projecting future developments and applications involving quantum information science.
Computation with Carbon Nanotube Devices
The remarkable properties of carbon nanotubes make them very promising candidates for future computing elements---both as a successor for silicon-basedtechnology and beyond.
Unintended Invitation: Organizational Wi-Fi Use By External Roaming Users
Unauthorized users risk civil and criminal liability; Wi-Fi network providers risk system intrusion and disruption.
Dynamic Decision Support Through Instantiation of UEML Representations
The resulting system inherits (on demand) from representations developed and maintained by partners engaged in business alliances.
Theoretical and Practical Complexity of Modeling Methods
Highlighting the importance of taking into account typical usage when estimating the complexity of a systems development method.

Using the ecological food chain as an analogy for agent classification.
Dealing with Change: Components Versus Services
Understanding the philosophy behind components and services is necessary before choosing a solution to deal with change in software design.
Shape the Future of Computing
ACM encourages its members to take a direct hand in shaping the future of the association. There are more ways than ever to get involved.
Get InvolvedCommunications 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.
