How do nations make successful transitions to democracies? Our understanding of how democracy functions--and under what circumstances it can be consolidated and strengthened--remains highly uneven. Recent events underscore the critical importance of expanding our understanding of democratic institutions and operations. Here McMahon and his distinguished contributors demonstrate how the dynamic process of democratization is shaped by the specific contexts in which it occurs; how the internal community plays a key role in the development of democracy; and how the ability to understand democratization requires both internal and external perspectives.

The contributors seek to improve the definitions of what constitutes a democracy and to determine how the effectiveness of democratic institutions might best be judged in order to better serve the analysis of and policy approaches to building democratic institutions. With fewer overtly authoritarian states in the post-Cold War world, a wealth of raw information and experience has begun to accumulate. Our understanding of democratic institutional performance requires us to look closely at the performance of the institutions themselves. The book contains chapters on public opinion, civil society, domestic institutions of governance, elections, globalization, international standards of democratic development, international assistance and academic research. A concluding chapter summarizes what democratization processes can teach us about democracy in a broader context.

Drought remains the biggest single threat from climate change to the production of key cereal crops, such as wheat and barley. Cereals also respond in complex ways to drought stress, making improved drought tolerance a challenging trait to achieve. With many cereals recognised as staple food crops due to their nutritional value, more research is required into improving drought tolerance as a means of ensuring the future food security of millions. Developing drought-resistant cereals reviews the wealth of research which addresses how to overcome this challenge in order to mitigate climate change effects in cereal production. This collection details our understanding of the mechanisms of drought tolerance, as well as the development of techniques for improving resistance, including phenotyping, genome-wide association studies (GWAS) and genome editing.

At the end of the High Middle Ages in Europe, with buying power and economic sophistication at a high, an itinerary detailing the toll stations along a commercial artery carrying eastern goods (from China, India and Iran) towards Europe was compiled, and later incorporated in the well-known trading manual of the Florentine bank official Pegolotti; Pegolotti was twice stationed in the city of Famagusta in Cyprus, which lay opposite the city of Ayas where the land route ended. The Il-Khanid capital, Tabriz in Iran, attracting expensive merchandise such as spices and silk from a variety of origins, was the road's starting-point. To demonstrate the importance of the route in its own time, parallel and contemporary routes in the Black Sea and the Levant are traced and the effect of trade on their cities noted. To compare the Ayas itinerary (1250s to 1330s) with previous periods the networks of commercial avenues in the previous period (1100-1250) and the subsequent one (1340s to 1500) are reconstructed. In each period the connection of east-west trade with the main movements of the European economy are fully drawn out, and the effects on the building history of the three main Italian cities concerned (Venice, Genoa and Florence) are sketched. Attention then turns to the Pegolotti itinerary itself. The individual toll stations are identified employing a variety of means, such as names taken from the Roman itineraries (Peutinger Table and Antonine Itinerary) and archaeological data; this allows the course of the track to be followed through diverse topography to the city of Sivas, then across plains and through passes to Erzurum and finally to Tabriz. A picture is drawn of the urban history of each major city, including Sivas, Erzurum and Tabriz itself, and of the other towns along the route.

Global food production and climate change among other concerns are societal issues that require major research input from crop science. While suggestions are abundant on how crop science can help to resolve these issues, many of the suggestions come from people who are not actually familiar with the challenges and requirements to modify crop plants grown under field conditions to achieve the necessary improvements. Efforts to alter a gene or even several genes have very rarely proven successful in having impact on crop production under realistic field conditions. This lack of success has not been addressed head on. This book serves as a reminder to crop scientists and others that open, clear-minded assessments of the entirety of evidence concerning a hypothesis is required before making claims of possible increases in crop performance. This attitude of skepticism is not a negative attitude but rather an employment of the cornerstone of scientific investigation based on formation and evaluation of hypotheses. Skeptical analyses are to be presented in the book on some of the common suggestions for improving crop plants. The six specific topics to be addressed are photosynthesis, seed number, nitrogen use efficiency, water use efficiency, crop water loss, and unconfirmed field observations. Each of the topics in this book, will first be reviewed to present the origins of the popular assumptions about how specific plant modification will result in improved crop performance. The review of the background information will be followed by an examination of the evidence, logic, and predicted outcomes for the assumed benefits of the modifications. Finally, each chapter will offer novel, alternate approaches to plant modification that have documented support for positively impacting crop performance. The book will not be written in specialized, detail language but offer access for those with a wide range of interests in options for increasing crop production in the future. The goal of the book is to provide information that is useful to those with interests ranging from climatologist to food-oriented sociologists. Of course, the topics covered will be of direct interest to those studying plant sciences, particularly crop scientists. The hope is to challenge a reader to re-examine some of her/his assumptions about crop improvement and approach the topic with a renewed practice of skepticism in formulating and evaluating hypotheses.

Model studies focus experimental investigations to improve our understanding and performance of systems. Concentrating on crop modeling, this book provides an introduction to the concepts of crop development, growth, and yield, with step-by-step outlines to each topic, suggested exercises and simple equations. A valuable text for students and researchers of crop development alike, this book is written in five parts that allow the reader to develop a solid foundation and coverage of production models including water- and nitrogen-limited systems.
