Germany, France and NATO

U.S. national strategy and U.S. Army doctrine explicitly establish the overwhelming need for, and value of, coalitions and alliances in the post-cold war era. Two generations of U.S. civil officials and military officers have been inculcated with the precept of NATO\u27s importance to security and stability in Europe. Free of the confines of the cold war, competing national interests and different national perceptions have transformed the Alliance. While NATO retains its value to U.S. national interests in Europe, the lack of a common threat now is producing a different Alliance. Clearly, if the Alliance is to survive and remain meaningful, an understanding of NATO and its political subtleties will be essential. To provide a wider understanding of the changed nature of the Alliance, Dr. Peter Schmidt of the Stiftung Wissenschaft und Politik in Ebenhausen, Germany, examines the current policies of France and Germany, the two largest continental NATO powers, toward NATO. Dr. Schmidt presented this paper in June 1994 to a roundtable sponsored by the American Institute for Contemporary Germany Studies and the Chief of Staff of the Army\u27s Strategic Outreach Program. Approximately two dozen European experts participated in this roundtable ably recorded by Ms Maria Alongi.https://press.armywarcollege.edu/monographs/1888/thumbnail.jp

Online Behaviour of Social Media Participants’ and Perception of Trust, Comparing Social Media Brand Community Groups and Associated Organized Marketing Strategies

AbstractThe purpose of this study was to assess social media participants’ perception of similarities and differences of the authenticity and trustworthiness of online advertising versus the authenticity and trustworthiness of respective online brand communities. We were looking at brand communities associated with Social Media that were formed on the basis of specific products or services. We further aimed to assess the trust individual participants in those brand communities obtain in contrast to information provided by companies and their marketing and public relations strategies. Our research then went beyond this comparative discussion in order to assess differences and similarities among individuals across different cultures. We believe that the connection between consumers may be stronger and perceived as equally or more trustworthy than the ‘traditional’ connection between an individual consumer and the information portrayed in marketing or public relations strategies by the company itself. We further believe that cultural differences in perceptions of trust may be minimal or non-existent

GridCertLib: a Single Sign-on Solution for Grid Web Applications and Portals

This paper describes the design and implementation of GridCertLib, a Java library leveraging a Shibboleth-based authentication infrastructure and the SLCS online certificate signing service, to provide short-lived X.509 certificates and Grid proxies. The main use case envisioned for GridCertLib, is to provide seamless and secure access to Grid/X.509 certificates and proxies in web applications and portals: when a user logs in to the portal using Shibboleth authentication, GridCertLib can automatically obtain a Grid/X.509 certificate from the SLCS service and generate a VOMS proxy from it. We give an overview of the architecture of GridCertLib and briefly describe its programming model. Its application to some deployment scenarios is outlined, as well as a report on practical experience integrating GridCertLib into portals for Bioinformatics and Computational Chemistry applications, based on the popular P-GRADE and Django softwares.Comment: 18 pages, 1 figure; final manuscript accepted for publication by the "Journal of Grid Computing

Effects of tutor-related behaviours on the process of problem-based learning

Tutors in a Problem-Based Learning (PBL) curriculum are thought to play active roles in guiding students to develop frameworks for use in the construction of knowledge. This implies that both subject-matter expertise and the ability of tutors to facilitate the learning process must be important in helping students learn. This study examines the behavioural effects of tutors in terms of subject-matter expertise, social congruence and cognitive congruence on students’ learning process and on their final achievement. The extent of students’ learning at each PBL phase was estimated by tracking the number of relevant concepts recalled at the end of each learning phase, while student achievement was based on students’ ability to describe and elaborate upon the relationship between relevant concepts learned. By using Analysis of Covariance, social congruence of the tutor was found to have a significant influence on learning in each PBL phase while all of the tutor-related behaviours had a significant impact on student achievement. The results suggest that the ability of tutors to communicate informally with students and hence create a less threatening learning environment that promotes a free flow exchange of ideas, has a greater impact on learning at each of the PBL phases as compared to tutors’ subject-matter expertise and their ability to explain concepts in a way that is easily understood by students. The data presented indicates that these tutor-related behaviours are determinants of learning in a PBL curriculum, with social congruence having a greater influence on learning in the different PBL phases

The Effective Fragment Molecular Orbital Method for Fragments Connected by Covalent Bonds

We extend the effective fragment molecular orbital method (EFMO) into treating fragments connected by covalent bonds. The accuracy of EFMO is compared to FMO and conventional ab initio electronic structure methods for polypeptides including proteins. Errors in energy for RHF and MP2 are within 2 kcal/mol for neutral polypeptides and 6 kcal/mol for charged polypeptides similar to FMO but obtained two to five times faster. For proteins, the errors are also within a few kcal/mol of the FMO results. We developed both the RHF and MP2 gradient for EFMO. Compared to ab initio, the EFMO optimized structures had an RMSD of 0.40 and 0.44 {\AA} for RHF and MP2, respectively.Comment: Revised manuscrip

Excited state intramolecular proton transfer in hydroxyanthraquinones: Toward predicting fading of organic red colorants in art.

Compositionally similar organic red colorants in the anthraquinone family, whose photodegradation can cause irreversible color and stability changes, have long been used in works of art. Different organic reds, and their multiple chromophores, suffer degradation disparately. Understanding the details of these molecules' degradation therefore provides a window into their behavior in works of art and may assist the development of improved conservation methods. According to one proposed model of photodegradation dynamics, intramolecular proton transfer provides a kinetically favored decay pathway in some photoexcited chromophores, preventing degradation-promoting electron transfer (ET). To further test this model, we measured excited state lifetimes of substituted gas-phase anthraquinones using high-level theory to explain the experimental results. The data show a general structural trend: Anthraquinones with 1,4-OH substitution are long-lived and prone to damaging ET, while excited state intramolecular proton transfers promote efficient quenching for hydroxyanthraquinones that lack this motif

Improving Time to MRI in the Emergency Room for Spinal Epidural Abscesses

Background Magnetic resonance images (MRI) is integral in assessing pathology. This is especially true in the emergency room (ER), where delays in diagnosing emergent neurologic pathologies, including spinal epidural abscesses (EDAs), where the morbidity can be severe if not addressed in time. This study aims to implement an expedited imaging pathway for this urgent / emergent pathology
