HCI is diverse, exciting, and expanding. Inevitably the HCI community pulls itself in different directions, sometimes with the result that some worthwhile research is under-valued. This paper explores the systemic issues, and makes some constructive suggestions.

A set HE w is said to be diverse with respect to a partition II of w if at least two pieces of I7 have an infinite intersection with H. A family of partitions of w has the Ramsey property if, whenever Co] is two-colored, some monochromatic set is diverse with respect to at least one partition in the family. We show that no countable collection of even infinite partitions of CIJ has the Ramsey p...

Replication has been used to build intrusion-tolerant systems, which are able to tolerate a limited number intrusions before the system is compromised. An important limitation of intrusion-tolerant systems is that if the system’s replicas are similar, once a flaw is discovered and exploited in one replica, then it is easy to replicate it on the other replicas, compromising the whole system. To ...

The theme articles in this issue highlight the breadth of computer graphics and visualization research, development, and applications that make up our research eld. They range from making sense of abstract data representing physiological processes to understanding and controlling real-world tasks as executed by arti cially real creatures—robots. This spectrum of research work and their applicat...

An appropriate use of neural computing techniques is to apply them to problems such as condition monitoring, fault diagnosis, control and sensing, where conventional solutions can be hard to obtain. However, when neural computing techniques are used, it is important that they are employed so as to maximise their performance, and improve their reliability. Their performance is typically assessed...

Myosins constitute a large superfamily of actin-dependent molecular motors. Phylogenetic analysis currently places myosins into 15 classes. The conventional myosins which form filaments in muscle and non-muscle cells form class II. There has been extensive characterization of these myosins and much is known about their function. With the exception of class I and class V myosins, little is known...

Previous authors have argued that ethnically diverse cities spend less on public goods than their homogeneous counterparts. In this paper, I present new evidence that challenges this claim. Incorporating improved measures of local expenditures in a panel study of US cities, I find that diversifying cities spend more per capita on most public goods – including police, fire protection, sanitation...

The design and use of materials in the nanoscale size range for addressing medical and health-related issues continues to receive increasing interest. Research in nanomedicine spans a multitude of areas, including drug delivery, vaccine development, antibacterial, diagnosis and imaging tools, wearable devices, implants, high-throughput screening platforms, etc. using biological, nonbiological, ...
