Financial management: Development of scales

This study is a contribution to the development of family resource management scales, specifically financial management scales. Principal axis factor analysis, with varimax rotation, is used to assess underlying relationships in 23 family resource management variables related to time and money resources. Reliability and content, construct, and criterion-related validity of the scales are assessed. Two scales that are reliable and have some degree of validity are developed: frequency of financial problems and frequency of financial management. The scales could be used in future research, teaching, or counseling to organize financial management concepts.Preparation of this research was supported in part by the Illinois Agricultural Experiment Station. Data were collected in conjunction with the cooperative regional research project NC-182, Family Resource Utilization as a Factor in Determining Economic Well-Being of Rural Families.

Inverse Combinatorial Optimization: A Survey on Problems, Methods, and Results

Given a (combinatorial) optimization problem and a feasible solution to it, the corresponding inverse optimization problem is to find a minimal adjustment of the cost function such that the given solution becomes optimum.Several such problems have been studied in the last twelve years. After formalizing the notion of an inverse problem and its variants, we present various methods for solving them. Then we discuss the problems considered in the literature and the results that have been obtained. Finally, we formulate some open problems.
