Modeling Crop Production Systems: Principles and Application
The use of simulation models is a necessity and also an aid in the decision-making process in sustainable agricultural systems. Organizing the experimental knowledge of crop production systems without the book keeping and deductive methods of mathematics is very difficult. This book aims to guide readers in the process by which the properties of the systems can be grasped in the framework of mathematical structure with minimal mathematical prerequisites. The objective of this book is to help the undergraduate, graduate and post-graduate students in the disciplines of agronomy, plant breeding, agricultural meteorology, crop physiology, agricultural economics, entomology, plant pathology, soil science and ecology (environmental science). This book may also be useful for administrators in various agricultural universities in order to direct research, extension and teaching activities. Planners at national and state levels may also benefit from this book.

Regionalization of African Higher Education (African Higher Education: Developments and Perspectives, 3)
p>Fundamentally, the book asks the question whether higher education regionalization in Africa is more rhetoric than reality. It discusses the progress to date on specific themes; identifies historical, political, sustainability and funding challenges; and concludes that while the impacts of regionalization efforts have not been fully realized there is cautious optimism for the future.</p>

Regression Models as a Tool in Medical Research
While regression models have become standard tools in medical research, understanding how to properly apply the models and interpret the results is often challenging for beginners. Regression Models as a Tool in Medical Research presents the fundamental concepts and important aspects of regression models most commonly used in medical research, including the classical regression model for continuous outcomes, the logistic regression model for binary outcomes, and the Cox proportional hazards model for survival data. The text emphasizes adequate use, correct interpretation of results, appropriate presentation of results, and avoidance of potential pitfalls.
After reviewing popular models and basic methods, the book focuses on advanced topics and techniques. It considers the comparison of regression coefficients, the selection of covariates, the modeling of nonlinear and nonadditive effects, and the analysis of clustered and longitudinal data, highlighting the impact of selection mechanisms, measurement error, and incomplete covariate data. The text then covers the use of regression models to construct risk scores and predictors. It also gives an overview of more specific regression models and their applications as well as alternatives to regression modeling. The mathematical details underlying the estimation and inference techniques are provided in the appendices.

Tropical Roots and Tuber Crops: Cassava, Sweet Potato, Yams and Aroids (Crop Production Science in Horticulture)
Root and tuber crops are important to agriculture, food security and income for 2.2 billion people in developing countries. These species produce large quantities of dietary energy and have stable yields under difficult environmental conditions. This second edition of Tropical Root and Tuber Crops is an authoritative treatment of four important root and tuber crops: cassava, sweet potato, yams, and aroids.
The same format is followed for each crop: Origin and History, Taxonomy and Botany, Breeding and Genetics, Developmental Physiology, Agronomy, Pests and Diseases, Post-Harvest Quality and Marketing. This new edition reviews the scientific literature produced during the last decade and presents major technical advancements. Modern molecular tools have been used to clarify the phylogeny, taxonomy and origin of these species. Similar advances have been made in physiology, agronomy, pathology and product chemistry. It is essential reading for students, researchers and horticulturists.
