This third volume in the series covers such topics as advances in working capital management.

Volume 4 in this research series contains nine papers. Following the tradition of the earlier volumes, it is similar in style to the first three volumes and illustrates ongoing research thrusts on a variety of financial economics issues that are germane to working capital management. The papers have been logically divided into three parts.

The first part of the volume focuses on the issues covering short-term interest rates, short-term financial management, and a cash balance model. Part two contains papers that examine the issue of trade credit analysis under a competitive pricing situation and an environment in which the level of sales fluctuates. Finally Part 3 departs from the traditional discussions on working capital management in that it explores dividend payouts and tax environment changes as a source of concern to treasury (and financial) managers.

This fourth volume presents a rich variety of papers that address an expanding facet of working capital management. It is hoped that the papers are found to be informative and act to stimulate research and practice in the area of treasury/financial management.

A Basic Approach to Precalculus Trigonometry: Preparing to Succeed in Calculus provides a concise, accessible introduction to trigonometry for high school and first-year college and university students. The book builds up the skill sets needed to succeed in college and university calculus courses. The material is organized into five chapters: rational functions; trigonometric functions; trigonometric identities and equations; applications of trigonometric functions, and sequences and series. Within each section all math terms are well-defined before instruction. The instruction is then organized into manageable, easily assimilated chunks with example problems and their solutions, followed by practice opportunities. Once an instructional unit is completed, all steps are listed in box format to help students organize and remember information. A Basic Approach to Precalculus Trigonometry breaks mathematical concepts down into steps that students can approach with ease and practice with confidence. The book prepares students who are new to trigonometry to succeed in more advanced courses.
