America’s Coming of Age: Daniel Walker Howe’s What Hath God Wrought
According to Daniel Walker Howe, the three decades between the end of the War of 1812 and the end of the Mexican War (1848) witnessed “the transformation of America.”1 Of what did this transformation consist? What drove it? What were its larger implications? These questions lie at the very center of historical writing about the early and middle decades of nineteenth- century America. Howe’s monumental effort goes far in answering them. In the process, he upends several well-known interpretations of the so-called Jacksonian period
IS Security Research Development: Implications For Future Researchers
Security within the context of Information Systems has long been a concern for both academics and practitioners. For this reason an extensive body of research has been built around the need for protecting vital technical systems and the information contained within them. This stream of research, termed Information Systems Security (ISS), has evolved with technology over the last several decades in numerous different ways. This evolution can create a great deal of difficulty for researchers to identify under-represented areas of ISS research as well as ensure all relevant areas of concern are addressed. The purpose of this paper is threefold: First, our goal is to map the progression of ISS research from past to present. Second, conduct a review of ISS literature from the date of the last holistic literature review to present, identifying key security thematic presented in these works, grouping them categorically. Lastly, from this review we explain the thematic these works resolve to and based on these categories we discuss where ISS research currently stands
A Counterpart to the Radial Orbit Instability in Triaxial Stellar Systems
Self-consistent solutions for triaxial mass models are highly non-unique. In
general, some of these solutions might be dynamically unstable, making them
inappropriate as descriptions of steady-state galaxies. Here we demonstrate for
the first time the existence in triaxial galaxy models of an instability
similar to the radial-orbit instability of spherical models. The instability
manifests itself when the number of box orbits, with predominantly radially
motions, is sufficiently large. N-body simulations verify that the evolution is
due neither to chaotic orbits nor to departures of the model from
self-consistency, but rather to a collective mode. The instability transforms
the triaxial model into a more prolate, but still triaxial, configuration.
Stable triaxial models are obtained when the mass contribution of radial orbits
is reduced. The implications of our results for the shapes of dark-matter halos
are discussed.Comment: 14 pages, 16 figure
Female college students’ perception of self-image based on fashion magazine advertising
The goal of this study was to examine how fashion magazine advertisements affect female college students’ perception of self-image. More specifically, do female college students have high or low self-image perception based upon the fashion magazine’s model images? Results of the study revealed female college students had positive perceptions of confidence with their physical body and body image. Before viewing the magazine advertising, participants liked their own body and would not change their body. However after viewing the magazine advertising, the participant’s confidence level decreased and participants liked their bodies less. While college women were not more likely to change their bodies after viewing the fashion magazine advertisements, college women perceived models to be beautiful, felt they would be more beautiful if they were to look like models, and would attract more people if they looked like the models. Fashion magazine advertising does appear to have an impact on female college students’ perception of self-image

Arctic fires re-emerging
Underground smouldering fires resurfaced early in 2020, contributing to the unprecedented wildfires that tore through the Arctic this spring and summer. An international effort is needed to manage a changing fire regime in the vulnerable Arctic
GAPDOCK: A genetic algorithm approach to protein docking in CAPRI round 1
As part of the first Critical Assessment of PRotein Interactions, round 1, we predict the structure of two protein-protein complexes, by using a genetic algorithm, GAPDOCK, in combination with surface complementarity, buried surface area, biochemical information, and human intervention. Among the five models submitted for target 1, HPr phosphocarrier protein (B. subtilis) and the hexameric HPr kinase (L. lactis), the best correctly predicts 17 of 52 interprotein contacts, whereas for target 2, bovine rotavirus VP6 protein-monoclonal antibody, the best model predicts 27 of 52 correct contacts. Given the difficult nature of the targets, these predictions are very encouraging and compare well with those obtained by other methods. Nevertheless, it is clear that there is a need for improved methods for distinguishing between correct and plausible but incorrect complexes. Proteins 2003;52:10-14
Nonlinear Fluid Computations in a Distributed Environment
The performance of a loosely and tightly-coupled workstation cluster is compared against a conventional vector supercomputer for the solution the Reynolds- averaged Navier-Stokes equations. The application geometries include a transonic airfoil, a tiltrotor wing/fuselage, and a wing/body/empennage/nacelle transport. Decomposition is of the manager-worker type, with solution of one grid zone per worker process coupled using the PVM message passing library. Task allocation is determined by grid size and processor speed, subject to available memory penalties. Each fluid zone is computed using an implicit diagonal scheme in an overset mesh framework, while relative body motion is accomplished using an additional worker process to re-establish grid communication
