This paper aims to discuss a simulation study for a multi‐product, two‐echelon inventory replenishment system. The paper compares a one‐warehouse N‐retailer replenishment system to a two‐warehouse, N‐retailer system with cost per unit of distribution and delivery lead‐times as the performance measures. The purpose is to demonstrate that under specific circumstances a two warehouse N‐retailer inventory replenishment system provides better customer service without significant changes in the cost.

Mathematical modeling and simulation methodology is used to test the performance of the proposed two warehouse N‐retailer system and statistical analysis is used to compare the performance of several scenarios.

The two warehouse replenishment system indeed reduces delivery lead‐times, used as a measure of customer service, under specific conditions such as controllable freight costs.

Caution should be exercised when interpreting these findings as the historical data used was from a single source. The paper did not investigate the effects of variable shipping costs from the manufacturing plant, warehouse and retailer. Future research could also consider multiple second level warehouses.

The findings provide a persuasive argument for manufacturers struggling with performance issues and channel relationships. Moreover, in addition to contributing to efficiency of distribution, two level systems can also enhance ability to adapt to local market conditions and to unexpected demand variations.

The model examined in this paper addressed a specific case for one company. While freight costs and warehousing costs will vary across companies, the cost represented here may be used as a gauge for evaluating systems with cost structures in the vicinity of those for the company represented in this paper. Additionally, the model is amenable to substitution of other firms' cost structures.

Academia is changing rapidly; the concept of attaining a college degree now encompasses not only the traditional ideas of attending classes on‐site at campuses but also through state‐of‐the‐art methods that deliver telecourses, now referred to as distance education. Distance education has opened the door of opportunity to a population of potential students who, not so long ago, felt a college degree was an impossible endeavor because of geographic location or personal restrictions. This boon to the students has posed a new set of challenges for libraries in providing academic support for the students engaged in distance learning. The Eastern Oregon Information Network (EOIN) was developed to provide dial‐in, remote access to CD‐ROM indexes, an interlibrary loan module, and an electronic mail system, which bridges the critical gap for the off‐campus student.

This study systematically addresses an important yet neglected question pertaining to the potentially time-varying effects of economic development on political democracy. Building on Huntington's insightful observations of alternating “waves” and “reverse waves” of democracy in world history, we deduce research hypotheses subject to empirical falsification and find, through a systematic analysis of the experiences of 87 countries from the 1960s to 1990s, that the impact of economic development on democracy shifted from the well-known U-shaped relationship to an inverted U-curve. These shifts occurred around 1980, a time point that corresponds to Diamond's classification of the end of the “second reverse wave” and beginning of the “third wave” of democratization. The finding thus demonstrates that the “wavy” progression of democracy in the world reflects historically changing dynamics of economic development and their impacts on political democracy over time.

Existing attempts to assess national development and processes of democratization suffer from conceptual and measurement challenges. This paper proposes a comprehensive concept of democratic development and develops a more inclusive concept of democracy to provide a common set of categories to evaluate its depth and quality.

In order to measure the depth and health of democracy, democratic development incorporates four categories of human progress, each measured by multiple variables. The four categories deemed important for human progress are general development, democratic health, democratic inclusiveness, and human capital. Components of democratic development incorporate existing measures of political and economic development to create a comprehensive and accessible measure of democratic development.

The comparative tables based on multiple goals of development clearly reveal that neither the GDP index nor the HDI are adequate measures of development. Democratic development can be more fully captured by four perspectives: development, democratic inclusiveness, democratic health, and human capital, providing a framework to measure progress in reform, democracy, and development, from public agencies up to the national level. This concept incorporates aspects and orientations of the capabilities approach to create a concept that is amenable to use as a self‐assessment tool and as a basis for comparison of development, broadly conceived.

This inclusive concept is particularly well suited for analyzing citizen satisfaction and democratic stability.

Rather than focusing on singular measures, the approach presented here offers a balanced set of measures aimed at providing a comprehensive view of the gamut of democratic and economic development processes relative to existing models that is more appropriate for self‐assessment/planning purposes than traditional measures, which may be more appropriate for statistical modeling purposes.

As CD‐ROM becomes more and more a standard reference and technical support tool in all types of libraries, the annual review of this technology published in Computers in Libraries magazine increases in size and scope. This year, author Susan L. Adkins has prepared this exceptionally useful bibliography which she has cross‐referenced with a subject index.
