The rapid growth of student loan debt has led to increased public attention on college students' financial aid and financial behaviour. This study addresses the psychological process underlying effective college student financial behaviour and its determinants. A model modified based on planned...

A new lower bound of the centered L2-discrepancy for four-level U-type designs is obtained. Our new lower bound is sharper and valid for a lot of designs more than other existing lower bound, which is a useful complement to the lower bounds of discrepancies.

Discrepancy measure can be utilized as a uniformity measure for comparing factorial designs. A so-called discrete discrepancy has been used to evaluate the uniformity of factorials. In this paper we give linkages among uniformity measured by the discrete discrepancy, generalized minimum...

Based on a so-called uniformity pattern, Fang and Qin [2005. Uniformity pattern and related criteria for two-level factorials. Sci. China Ser. A 48, 1-11] proposed the minimum projection uniformity criterion to assess and compare two-level factorials. In present paper, we study applications of...

Supersaturated designs have become increasingly popular in recent years because of their potential in saving run size and the technical novelty. In this paper, the minimum generalized aberration (MGA) criterion proposed by Ma and Fang (2001) (and another two equivalent criteria proposed by Xu...

To capture the heterozygous of vertex degrees of networks and understand their distributions, a class of random graph models parameterized by the strengths of vertices, are proposed. These models are equipped in the framework of mutually independent edges, where the number of parameters matches...

Purpose The purpose of this paper is to report on the findings and lessons that were learned from the many cases of internet fraud complaints that are gathered by the Federal Trade Commission in the USA. The implications that are contained in the behavior of the complaints and trends identified...
