Paper Session III-D - NASA Industry, and Secondary Education: A Blueprint for the Future

For years, the face of man\u27s exploration of space has been one of individuals. In recent times, that face has turned to one of partnership and cooperation. One needs to look only as far as the International Space Station to see what can be accomplished through that cooperation. This concept should not only apply to governments and corporations, but to all interested parties in the exploration of space. Throughout the history of space exploration, post-secondary institutions have played an important but often small part in that exploration. The role they played is one mainly of a think tank, developing new ideas and evaluating data. There was even the occasional experiment or payload. However, today\u27s post-secondary institutions are changing. Schools are becoming more competitive and the students desire more participation. This creates a resource of great potential for space exploration

Distributed computing system with dual independent communications paths between computers and employing split tokens

This is a distributed computing system providing flexible fault tolerance; ease of software design and concurrency specification; and dynamic balance of the loads. The system comprises a plurality of computers each having a first input/output interface and a second input/output interface for interfacing to communications networks each second input/output interface including a bypass for bypassing the associated computer. A global communications network interconnects the first input/output interfaces for providing each computer the ability to broadcast messages simultaneously to the remainder of the computers. A meshwork communications network interconnects the second input/output interfaces providing each computer with the ability to establish a communications link with another of the computers bypassing the remainder of computers. Each computer is controlled by a resident copy of a common operating system. Communications between respective ones of computers is by means of split tokens each having a moving first portion which is sent from computer to computer and a resident second portion which is disposed in the memory of at least one of computer and wherein the location of the second portion is part of the first portion. The split tokens represent both functions to be executed by the computers and data to be employed in the execution of the functions. The first input/output interfaces each include logic for detecting a collision between messages and for terminating the broadcasting of a message whereby collisions between messages are detected and avoided

Patron-Driven Acquisition: An Introduction and Literature Review

Introductory article to the Special Issue: Patron-Driven Acquisition: Current Successes and Future Direction

Academic E-Books: Publishers, Librarians, and Users

Academic E-Books: Publishers, Librarians, and Users provides readers with a view of the changing and emerging roles of electronic books in higher education. The three main sections contain contributions by experts in the publisher/vendor arena, as well as by librarians who report on both the challenges of offering and managing e-books and on the issues surrounding patron use of e-books. The case study section offers perspectives from seven different sizes and types of libraries whose librarians describe innovative and thought-provoking projects involving e-books. Read about perspectives on e-books from organizations as diverse as a commercial publisher and an association press. Learn about the viewpoint of a jobber. Find out about the e-book challenges facing librarians, such as the quest to control costs in the patron-driven acquisitions (PDA) model, how to solve the dilemma of resource sharing with e-books, and how to manage PDA in the consortial environment. See what patron use of e-books reveals about reading habits and disciplinary differences. Finally, in the case study section, discover how to promote scholarly e-books, how to manage an e-reader checkout program, and how one library replaced most of its print collection with e-books. These and other examples illustrate how innovative librarians use e-books to enhance users’ experiences with scholarly works.https://docs.lib.purdue.edu/purduepress_ebooks/1036/thumbnail.jp

Introduction to Academic E-Books

With so many advantages, it seems logical that librarians would be eager to switch from purchasing books in print to embrace the electronic format. However the transition to e-books in academic libraries has not been a smooth or quick one and the reasons are myriad and complicated. Aware that this is still a time of transition and that there are many issues surrounding the e-book, the editors set out to present the state of e-books in academic libraries today. They invited knowledgeable publishers and librarians to write about the current challenges, successes, and trends. In addition, there is a section that analyzes new data about user interaction with e-books and an essay written by a teaching faculty member who uses and encourages her student to use e-book

A Conserved Functional Domain of Drosophila Coracle Is Required for Localization at the Septate Junction and Has Membrane-organizing Activity

This is the published version, also available here: http://dx.doi.org/10.1083/jcb.140.6.1463.The protein 4.1 superfamily is comprised of a diverse group of cytoplasmic proteins, many of which have been shown to associate with the plasma membrane via binding to specific transmembrane proteins. Coracle, a Drosophila protein 4.1 homologue, is required during embryogenesis and is localized to the cytoplasmic face of the septate junction in epithelial cells. Using in vitro mutagenesis, we demonstrate that the amino-terminal 383 amino acids of Coracle define a functional domain that is both necessary and sufficient for proper septate junction localization in transgenic embryos. Genetic mutations within this domain disrupt the subcellular localization of Coracle and severely affect its genetic function, indicating that correct subcellular localization is essential for Coracle function. Furthermore, the localization of Coracle and the transmembrane protein Neurexin to the septate junction display an interdependent relationship, suggesting that Coracle and Neurexin interact with one another at the cytoplasmic face of the septate junction. Consistent with this notion, immunoprecipitation and in vitro binding studies demonstrate that the amino-terminal 383 amino acids of Coracle and cytoplasmic domain of Neurexin interact directly. Together these results indicate that Coracle provides essential membrane-organizing functions at the septate junction, and that these functions are carried out by an amino-terminal domain that is conserved in all protein 4.1 superfamily members

Technology Policy: A Fixture on the National Agenda

In his commentary, Robert Kidd, president of the Maine Science and Technology Foundation, echoes the call by Rycroft, Kash and Adams in their article [this issue] for a new technology policy focused on industrial competitiveness. He defines a partnership role for states in the design and implementation of national technology priorities. James Ward, IV and Richard Hill, raise several questions in their commentary. Can we rely on the federal government to successfully direct this policy area? How would a new technology policy impact the roles and responsibilities of the private and public sectors? What can we learn from partnerships between universities and industry that have led to innovation and enhanced competitiveness and did they result from good policy or practical incentives at the local level

Thioxoethenylidene (CCS) as a bridging ligand

The reaction of [Mo(≡CBr)(CO)2(Tp*)] (Tp* = hydrotris(3,5-dimethylpyrazol-1-yl)borate) with [Fe2(μ-SLi)2(CO)6] affords, inter alia, the unsymmetrical binuclear thioxoethenylidene complex [Mo2(μ,σ(C):η2(C′S)-CCS)(CO)4(Tp*)2], which may be more directly obtained from [Mo(≡CBr)(CO)2(Tp*)] and Li2S. The reaction presumably proceeds via the intermediacy of the bis(alkylidynyl)thioether complex S{C≡Mo(CO)2(Tp*)}2, which was, however, not directly observed but explored computationally and found to lie 78.6 kJ mol–1 higher in energy than the final thioxoethenylidene product. Computational interrogation of the molecules [M2(μ-C2S)(CO)2(Tp*)2] (M = Mo, W, Re, Os) reveals three plausible coordination modes for a thioxoethenylidene bridge which involve a progressive strengthening of the C–C bond and weakening of the M–C and M–S bonds, as might be expected from simple effective atomic number considerations.This work was supported by the Australian Research Council (DP130102598 and DP110101611)
