Pullbacks of Prüfer rings

AbstractIn this paper we consider five extensions of the Prüfer domain notion to commutative rings with zero-divisors and investigate their behavior in a special type of pullback called a conductor square. That is, for a pair of rings R⊂T with non-zero conductor of T into R, we find necessary and sufficient conditions on the rings T, T/C, and R/C in order that R has one of the five Prüfer conditions

An investigation of IBM's Business Systems Planning (BSP) as a suitable methodology for strategic information systems planning for the Naval Reserve

This research examines the Naval Reserve organization, Information systems (IS) planning, and IBM's Business System Planning (BSP) methodology. The Naval Reserve is analyzed in the context of IS planning requirements. The information needs of the organization are examined as well as that organization's current IS planning process. BSP is investigated as an alternate planning methodology. A partial analysis of the Naval Reserve using BSP is used as an illustration of the methodology. It highlights some of the information related complexities and organizational influences that confront the IS planner.http://archive.org/details/investigationofi00duckLieutenant, United States Naval ReserveApproved for public release; distribution is unlimited

Globalizing Terror

The globalization of terror is something new. It goes hand in hand with the globalization of the media. The creation of new media technology has created a public space in which political actors may perform: Terrorists are some of the actors who can now play on a global stage. Kosovo, Israel/Palestine, the twin towers terror is not a sometime thing. Man's inhumanity toward his fellow men makes terror a constant in human affairs. Not very long ago most of the terror was hidden beyond our willingness to wait for the news. That is no longer true. We experience the terror around the world

A New Version of Reimers' law of Mass Loss Based on a Physical Approach

We present a new semi-empirical relation for the mass loss of cool stellar winds, which so far has frequently been described by "Reimers' law". Originally, this relation was based solely on dimensional scaling arguments without any physical interpretation. In our approach, the wind is assumed to result from the spill-over of the extended chromosphere, possibly associated with the action of waves, especially Alfven waves, which are used as guidance in the derivation of the new formula. We obtain a relation akin to the original Reimers law, but which includes two new factors. They reflect how the chromospheric height depends on gravity and how the mechanical energy flux depends, mainly, on effective temperature. The new relation is tested and sensitively calibrated by modelling the blue end of the Horizontal Branch of globular clusters. The most significant difference from mass loss rates predicted by the Reimers relation is an increase by up to a factor of 3 for luminous late-type (super-)giants, in good agreement with observations.Comment: 12 pages, 4 figures, accepted by ApJ Letter
