Comparing Teacher Education and Finance Majors’ Agreement with Financial Morality Topics

The authors describe findings of a survey that contains items related to financial morality. They analyzed responses of 382 teacher education majors and finance majors at a Midwestern institution of higher learning. The study found highest agreement with items measuring business responsibilities, and lowest agreement with items related to wealth distribution. It notes significant differences and varying effect sizes among education and finance majors’ interpretation of items concerning business responsibility, wealth distribution, and business management. Analysis of items concerning consumer attitudes and consumer behaviors found significant differences and moderate effect sizes. The authors argue for additional research that explores the concepts related to financial morality and provide suggestions for related study.

The Motion of a Charged Particle in Homogenous Time-Varying Magnetic Field

This paper will discuss the motion of a non-relativistic, non-radiating charged particle in an infinite homogeneous magnetic field which varies linearly with time. We shall assume the motion to be confined to a plane perpendicular to the magnetic field

Why Do U.S. Firms Hold So Much More Cash Than They Used To?

The average cash to assets ratio for U.S. industrial firms increases by 129% from 1980 to 2004. Because of this increase in the average cash ratio, American firms at the end of the sample period can pay back their debt obligations with their cash holdings, so that the average firm has no leverage when leverage is measured by net debt. This change in cash ratios and net debt is the result of a secular trend rather than the outcome of the recent buildup in cash holdings of some large firms. It is concentrated among firms that do not pay dividends. The average cash ratio increases over the sample period because the cash flow of American firms has become riskier, these firms hold fewer inventories and accounts receivable, and the typical firm spends more on R&D. The precautionary motive for cash holdings appears to explain the increase in the average cash ratio.

Library & Administrative Support for Civil & Environmental Engineering Scholars

As university researchers’ needs for information and research support continue to change over time, it is important for university libraries to assess how well their services fit with the current research environment. Collecting perspectives from scholars in particular fields is a key step in developing and redeveloping library support for research. The Supporting Civil and Environmental Engineering Scholars project was coordinated by Ithaka S+R and sponsored by the American Society of Civil Engineers (ASCE) to explore the research and information needs of scholars in the fields of civil and environmental engineering. All phases of the research process, from idea generation to dissemination of results, were included in the research. Teams were assembled at 11 universities (Appendix 1), including Iowa State University (ISU)

Testing the impact of direct and indirect flood warnings on population behaviour using an agent-based model

This paper uses a coupled hydrodynamic agent-based model (HABM) to investigate the effect of direct or indirect warnings in flood incident response. This model uses the LISFLOOD-FP hydrodynamic model and the NetLogo agent-based framework and is applied to the 2005 flood event in Carlisle, UK. The hydrodynamic model provides a realistic simulation of detailed flood dynamics through the event, whilst the agent-based model component enables simulation and analysis of the complex, in-event social response. NetLogo enables alternative probabilistic daily routine and agent choice scenarios for the individuals of Carlisle to be simulated in a coupled fashion with the flood inundation. Specifically, experiments are conducted using a novel “enhanced social modelling component” based on the Bass diffusion model. From the analysis of these simulations, management stress points (predictable or otherwise) can be presented to those responsible for hazard management and post-event recovery. The results within this paper suggest that these stress points can be present, or amplified, due to a lack of preparedness or a lack of phased evacuation measures. Furthermore, the methods outlined here have the potential for application elsewhere to reduce the complexity and improve the effectiveness of flood incident management. The paper demonstrates the influence that emergent properties have on systematic vulnerability and risk from natural hazards in coupled socio-environmental systems

The effect of topology on the structure and free energy landscape of DNA kissing complexes

We use a recently developed coarse-grained model for DNA to study kissing complexes formed by hybridization of complementary hairpin loops. The binding of the loops is topologically constrained because their linking number must remain constant. By studying systems with linking numbers -1, 0 or 1 we show that the average number of interstrand base pairs is larger when the topology is more favourable for the right-handed wrapping of strands around each other. The thermodynamic stability of the kissing complex also decreases when the linking number changes from -1 to 0 to 1. The structures of the kissing complexes typically involve two intermolecular helices that coaxially stack with the hairpin stems at a parallel four-way junction
