Considering that security education needs to train students to deal with security problems in real environments, we developed new media for teaching applied cryptography and network security. They permit students to gain real-life security experience from virtual laboratories on CD, DVD, or online. The application of those media is helpful to reduce investment and administration costs as well a...

The study of memory for event duration in pigeons has, for the most part, centered on an unusual behavioral phenomenon and an interesting theoretical explanation for it. A typical experiment on memory for event duration involves trials initiated by a sample stimulus that is either short or long in duration (e.g., 2 vs. 10 sec of houselight) and that is later followed by the simultaneous present...

Fostering Within-Family Human Capital Investment: An Intragenerational Insurance Perspective of Social Security We develop a general equilibrium stochastic OLG model with heterogenous households. Households differ with respect to their productivity. Productivity depends stochastically on parents' unobservable investment in their child's human capital and an aggregate productivity shock. We intr...

This paper builds a bridge between research on regulatory focus in motivation and classification learning. It tests the hypothesis that a fit between the situational regulatory focus and the reward structure of the task leads to greater cognitive flexibility than a mismatch between situational focus and the reward structure and that the fit between the regulatory focusinduced processing charact...

This paper incorporates human capital into the well-established portfolio theory by allowing for job security in personal portfolio choice. Our model predicts that young people hold more cash to hedge against risk associated with human capital (layoff risk). As people age, layoff risk decreases, and consequently, they invest in more risky assets – stocks in their portfolios. However, as people ...

Decisions are often based on the results of quantitative analysis. To gain confidence in these results, some indication of their quality is needed. Measurement uncertainty, as proposed by the International Organization for Standardization (ISO), is a way to express this quality. Most measurement techniques compare references and therefore need to be calibrated. Usually least squares methods ign...
