The crucial role played by calcium as a cellular messenger has become increasingly evident, as has the recognition that cells spend much energy in maintaining the cytosolic concentration of this cation both constant and low. It is thought they do this to avoid precipitating phosphate, needed as a source of bond energy and to modulate protein structure. Moreover, since calcium that does enter the cell must be disposed with, processes that utilize calcium have evolved, e.g. secretion, contraction, signaling, to name just some. New knowledge concerning the processes of cellular calcium entry, extrusion and the fate of intracellular calcium has accumulated in recent years. Much has also been learned about calcium transport by and across epithelial cells. It seems logical to think that the processes of calcium entry, extrusion and intracellular handling are similar in all cells. We have therefore assembled in one volume overviews and research reports of transport and cellular calcium regulation so as to explore similarities and differences between cells that utilize calcium for metabolic purposes and those whose primary function is transport.

After Piaget proves that Jean Piaget's work is critical for understanding some of the most current proposals in the study of psychological development. It analyzes Piaget's legacy, moving beyond the harsh critiques that have circulated since he lost prominence. It also brings together new developments and research practices that have grown out of Jean Piaget's tradition, while providing a retrospective glance into the intellectual atmospheres of different periods at which the contributors encountered Piaget.This book reveals the richness and coherence of the School of Geneva's research during the last decades before Piaget's death. Contributions from scholars who formed part of the School of Geneva during the 1970s and '80s demonstrate Piaget's influence on such diverse fields as infant development, ethnology, neuropsychology, semiotic development, and epistemology. After Piaget is part of Transaction's History and Theory of Psychology series.
