Forestry today, like many other sectors that traditionally rely on material goods, faces significant global drivers of societal change that are less often addressed than the environmental concerns commonly in the spotlight of scientific, political, and news media. There are three major interconnected issues that are challenging forestry at its foundation: urbanization, tertiarization, and globalization. These issues are at the core of this book. The urbanization of society, a process in development from the first steps of industrialization, is particularly significant today with the predominance and quick growth rate of the world's urban population. Ongoing urbanization is creating new perspectives on forestry, inducing changes in its social representation, and changing lifestyles and practices with a tendency toward dematerialization. The process of urbanization is also creating a disconnect and in some ways is leaving behind rurality, the sector of society where forestry has traditionally developed and taken place over centuries. The second issue covered in this book is the tertiarization of the economy. In society today, the sector of services largely dominates the economy and occupies the major part of the world's active population. This ongoing process modifies professional modalities and ways of life and opens new doors to forests through the immaterial goods they provide. It also profoundly changes the framework, rules, processes, means of production, exchanges between economic factors, and the processes of innovation. The third issue is undoubtedly globalization in its economic, political, and social components. Whether it's through bridging distances, crossing borders, accelerating changes, standardizing practices, leveling hierarchical structures, or pushing for interdependence, globalization impacts everyone, everywhere in multiple ways. Forestry is no exception. Forestry in the Midst of Global Changes focuses on these global drivers of change from the perspective of their relationships with how society functions. By analyzing them in depth through multidisciplinary, interdisciplinary, and even transdisciplinary approaches, this book is helping to design the forestry of tomorrow.

Pancreatic a-cell biophysics has undergone a veritable informa tion explosion in the past two years. Single channel and macroscopic currents have become easily accessible following the introduction of the patch clamp technique. In addition to this new approach, further development of techniques for optical measurements, ion-sensitive microelectrodes, permeabilized cells and mathematical modelling have recently added to the now classical techniques of membrane potential recording and tracer flux measurement. The International Workshop on Biophysics of the Pancreatic a-Cell held in Alicante (Spain) on Sep tember 30 - October 1, 1985, has now given us the opportunity to share experiences with these new techniques applied to the a-cell. Further more this was the first occasion for most of the groups doing patch clamp studies of the a-cell to decide on appropriate nomenclature and to debate the different characteristics of the a-cell ionic channels. To make this information available to the larger scientific community a record of the meeting has been assembled in this book. It is a collection of research papers by leading scientists at the meet ing working on biophysical, biochemical and physiological aspects. of secretion. We grouped their contributions in seven sections, includ ing new experimental approaches, K-channels, Ca-channels, role of ionic channels, intracellular ionized calcium, neural regulation and mechanisms of insulin release. Each section gives an account of the state of the problem at the time of the meeting, and the subjects are analyzed from the different perspectives of the various contributors."
