Waiting for Dead Men’s Shoes:Origins and Development of the U.S. Navy’s OfficerPersonnel System, 1793–1941

Donald Chisholm has provided us with an important book. It is the first comprehensive history of the development of the U.S. Navy’s officer personnel system. Others have provided portions of the picture; Christopher McKee’s A Gentlemanly and Honorable Profession: The Creation of the U.S. Naval Officer Corps, 1794–1815 is an excellent treatment of the early years. But the Royal Navy, from which many American practices derive, is more thoroughly covered

A New and Unifying Approach to Spin Dynamics and Beam Polarization in Storage Rings

With this paper we extend our studies [1] on polarized beams by distilling tools from the theory of principal bundles. Four major theorems are presented, one which ties invariant fields with the notion of normal form, one which allows one to compare different invariant fields, and two that relate the existence of invariant fields to the existence of certain invariant sets and relations between them. We then apply the theory to the dynamics of spin-1/2 and spin-1 particles and their density matrices describing statistically the particle-spin content of bunches. Our approach thus unifies the spin-vector dynamics from the T-BMT equation with the spin-tensor dynamics and other dynamics. This unifying aspect of our approach relates the examples elegantly and uncovers relations between the various underlying dynamical systems in a transparent way

An Informal Summary of a New Formalism for Classifying Spin-Orbit Systems Using Tools Distilled from the Theory of Bundles

We give an informal summary of ongoing work which uses tools distilled from the theory of fibre bundles to classify and connect invariant fields associated with spin motion in storage rings. We mention four major theorems. One ties invariant fields with the notion of normal form, the second allows comparison of different invariant fields and the two others tie the existence of invariant fields to the existence of certain invariant sets. We explain how the theorems apply to the spin dynamics of spin-$1/2$ and spin-$1$ particles. Our approach elegantly unifies the spin-vector dynamics from the T-BMT equation with the spin-tensor dynamics and other dynamics and suggests an avenue for addressing the question of the existence of the invariant spin field.Comment: Based on a presentation at Spin2014, The 21st International Symposium on Spin Physics, Beijing, China, October 2014.

Fraternities and Sororities: Developing a Compelling Case for Relevance in Higher Education

With over 60 collective years of serving the fraternal movement as fraternity/sorority members, chapter advisors, fraternity/sorority life advisors, and (inter)national fraternal leaders, we approached writing about the experiences of college students who participate in fraternities and sororities from an affirming and positive perspective. We believe these distinctive and intergenerational organizations can provide a forum for college students to create meaningful, well-rounded, and learning-oriented experiences. Deep and long-standing challenges continue to exist, but the juxtaposition of the best and worst actions of today\u27s college students make fraternities and sororities among the most complex organizations on college campuses. In addition, there is a high level of interaction between and among students, the campus community, administrators, faculty, alumni, and external stakeholders such as parents and (inter)national fraternity/sorority headquarters. Such dynamic experiences can create shared and distinctive realities for students that are integral to student development. This chapter provides insight into the historical and modern-day complexities that affect students\u27 experiences in fraternities and sororities and offers a framework for working with this population across contexts.https://scholarworks.wm.edu/asbookchapters/1113/thumbnail.jp

The Nixon Doctrine & The Navy

Most people understand that the Nixon Doctrine involves a lowering of the U.S. profile throughout the world and further, places some limitations on our willingness to intervene overseas. The author is not nearly so confident that there is widespread understanding of some of its other implications and believes that it would be a mistake to view the Nixon Doctrine as an arbitrary decision by a single administration. On the contrary, the Nixon Doctrine seems to have been dictated by the course of world events

The Uses of Naval Force

There is a striking contrast between the concerns which dominate naval planning and force structure and those things we actually do with the fleet. For 30 years the specter of a major war with the Soviet Union has been the contingency that has dominated our planning; yet none of us, in careers filled with naval operations in support of national policy, has ever exchanged anything more lethal than gun salutes with a Soviet warship
