If philosophical moral reflection improves moral behavior, one might expect ethics professors to behave morally better than socially similar non-ethicists. Under the assumption that forms of political engagement such as voting have moral worth, we looked at the rate at which a sample of professional ethicists—and political philosophers as a subgroup of ethicists—voted in eight years’ worth of e...

T opological fluid dynamics is a young mathematical discipline that studies topological features of flows with complicated trajectories and their applications to fluid motions, and develops group-theoretic and geometric points of view on various problems of hydrodynamical origin. It is situated at a crossroads of several disciplines, including Lie groups, knot theory, partial differential equat...

The UDP-3-O-(R-3-hydroxymyristoyl)-N-acetylglucosamine deacetylase LpxC catalyzes the committed reaction of lipid A biosynthesis, an essential pathway in Gram-negative bacteria. We report the backbone resonance assignments of the 34 kDa LpxC from Escherichia coli in complex with the antibiotic L-161,240 using multidimensional, multinuclear NMR experiments. The H chemical shifts of complexed L-1...

The only commonly known source for some in situ measured spectral radiances is ISO 17321-1. It describes the principle of how the color characterization of a digital camera works and provides spectral radiances for 14 common objects. This paper summarizes the results of a project that was started to collect several hundred measurements of all different kinds of objects under various illuminatio...

10 NOTICES OF THE AMS VOLUME 54, NUMBER 1 Sensors and Sense-ability A sensor is a device that measures some feature of a domain or environment and returns a signal from which information may be extracted. Sensors vary in scope, resolution, and ability. The information they return can be as simple as a binary flag, as with a metal detector that beeps to indicate a detection threshold being cross...

Introduction Since the early 1990s, parts of Africa’s Great Lakes Region have experienced political strife, armed conflict and population displacements with severe humanitarian consequences. Despite great progress towards sustainable peace in all the countries of the region, sporadic violence continues in some areas, particularly in the Eastern Democratic Republic of Congo (DRC). Conflicts in t...

Since its beginning in 1983, the GRASP News has chronicled the research efforts of the Grasp Laboratory. This edition, which covers developments for the year 1990, follows the format of previous editions. The Feature Article, however, in a departure from tradition does not highlight a particular research project. Helen Anderson presents a summary of the Laboratory research projects and activiti...

Background: The project was conceived in 1994 following formulation of a FEAST hypothesis. This stated that the software evolution process is a feedback system and must be treated as such to achieve major process improvement. Three self-funding international workshops were held at IC [fea94,5] to explore the hypothesis, with some 40 participants from the UK, Europe and North America at each. Fo...
