Book Description
The intricacies of plant growth and development present a fascinating intellectual challenge, and yet our understanding of the subject has increased relatively slowly, despite the application of many different experimental approaches. Now, however, the introduction of molecular methods, coupled with genetic transformation technology, has provided a change in pace, and fundamental advances are occurring rapidly. This volume, the second in our Plant Biotechnology series, shows how we are beginning to understand the molecular basis of plant growth and development, and are thus moving from the descriptive to the predictive stage. The ability, discussed in chapter one, to generate a fivefold change in plant height by overexpression of a single gene for the photoreceptor phytochrome heralds not only a new phase in plant photobiology but also highlights the close relationship between fundamental knowledge and commercial application. Other chapters review progress in our understanding of the molecular basis of hormone action and processes such as tuber development, seed protein synthesis and deposition, fruit ripening, and self-recognition during pollination. The successful uses of antisense genes to alter the colour and pattern of flowers and to change the enzymic composition of ripening fruit are also discussed, together with identification and down regulation of a gene involved in ethylene synthesis by antisense technology. Opportunities are considered for altering the composition and quality of harvested plant organs and for using plants to synthesise novel products.

Book Description
Developmental Regulation: Aspects of Cell Differentiation draws together some studies which are directed toward the orderly changes in cell phenotypes that are understood to be developmental in nature. Organized into nine chapters, the book begins with a concise overview of the studies on molecular synthesis during early development. It then addresses the developmental regulation in cotton seed embryogenesis and germination; relation of hormonal regulation to the possible control of RNA and protein biosynthesis; transitions in differentiation by the cellular slime molds; and interrelationships of genes, enzymes, structures, and phenotypes in morphogenesis. It also explains the colony differentiation in green algae; cytology of developing vertebrate skeletal muscle; some comparative aspects of cardiac and skeletal myogenesis; and differentiation of cartilage in the limb.

Book Description
How we raise young children is one of today's most highly personalized and sharply politicized issues, in part because each of us can claim some level of "expertise." The debate has intensified as discoveries about our development-in the womb and in the first months and years-have reached the popular media. How can we use our burgeoning knowledge to assure the well-being of all young children, for their own sake as well as for the sake of our nation? Drawing from new findings, this book presents important conclusions about nature-versus-nurture, the impact of being born into a working family, the effect of politics on programs for children, the costs and benefits of intervention, and other issues. The committee issues a series of challenges to decision makers regarding the quality of child care, issues of racial and ethnic diversity, the integration of children's cognitive and emotional development, and more. Authoritative yet accessible, From Neurons to Neighborhoods presents the evidence about "brain wiring" and how kids learn to speak, think, and regulate their behavior. It examines the effect of the climate-family, child care, community-within which the child grows.

Book Description
Provides a developmental perspective of the regulation and dysregulation of emotion, in particular, how children learn about feelings and how they learn to deal with both positive and negative feelings. Emotion regulation involves the interaction of physical, behavioral, and cognitive processes in response to changes in one's emotional state. The changes can be brought on by factors internal to the individual (e.g. biological) or external (e.g. other people). Featuring contributions from leading researchers in developmental psychopathology, the volume concentrates on recent theories and data concerning the development of emotion regulation with an emphasis on both intrapersonal and interpersonal processes. Original conceptualizations of the reciprocal influences among the various response systems--neurophysiological-biochemical, behavioral-expressive, and subjective-experiential--are provided, and the individual chapters address both normal and psychopathological forms of emotion regulation, particularly depression and aggression, from infancy through adolescence. This book will appeal to specialists in developmental, clinical, and social psychology, psychiatry, education, and others interested in understanding the developmental processes involved in the regulation of emotion over the course of childhood.

Book Description
Adolescenceâ€"beginning with the onset of puberty and ending in the mid-20sâ€"is a critical period of development during which key areas of the brain mature and develop. These changes in brain structure, function, and connectivity mark adolescence as a period of opportunity to discover new vistas, to form relationships with peers and adults, and to explore one's developing identity. It is also a period of resilience that can ameliorate childhood setbacks and set the stage for a thriving trajectory over the life course. Because adolescents comprise nearly one-fourth of the entire U.S. population, the nation needs policies and practices that will better leverage these developmental opportunities to harness the promise of adolescenceâ€"rather than focusing myopically on containing its risks. This report examines the neurobiological and socio-behavioral science of adolescent development and outlines how this knowledge can be applied, both to promote adolescent well-being, resilience, and development, and to rectify structural barriers and inequalities in opportunity, enabling all adolescents to flourish.

Book Description
Human behavior is very flexible and ontogenetic potential adds to the scope of variability of developmental paths. Therefore, development in the life course needs to be regulated. Developmental regulation by the individual is scaffolded by external constraints. External constraints to development based on biological aging, institutional age-grading, and internalized age norms provide an age-graded agenda for striving for developmental growth and avoiding developmental decline. The life-span theory of control proposes that control of one's environment is the key to adaptive functioning throughout the life span. The theory identifies the evolutionary roots and the life-span developmental course of man striving to control the environment (primary control) and the self (secondary control). Primary control is directed at producing effects in the external world, while secondary control influences the internal world so as to optimize the motivational resources for primary control. In this 1999 book, a series of studies illustrate the rich repertoire of the human control system to master developmental challenges in various age periods and developmental ecologies.

Book Description
As humans, we self-regulate whenever we adapt our emotions and actions to situational requirements and to internalized social standards and norms. Self-regulation encompasses skills such as paying attention, inhibiting reflexive actions, and delaying gratification. We need self-regulation for navigating in the social world (e.g., when we inhibit revealing a secret, even though it is tempting to tell it), academic life (e.g., when we study for the test, even though we would prefer to watch our favorite TV show), and much more-indeed, in every aspect of life. While both environmental and genetic factors have direct, long-lasting influences on an individual's ability to self-regulate, these factors also interact with each other in critical ways. On one hand, environmental factors such as parental attachment can shape the epigenetics and the expression of the individual genotype; on the other hand, gene variations may increase vulnerability to certain environmental pathogens. This book presents self-regulation as a crucial link between genetic predisposition, early experience, and later adult functioning in society. Individual chapters examine what self-regulation is, how it functions, how genetic and environmental factors influence its development, how it affects social and academic competence in childhood and adulthood, what pathologies can emerge if it is under-developed, and how it might be fostered in children. Part of the Human Brain Development Series, edited by Michael Posner, this book will appeal to developmental psychologists, developmental neuroscientists, educational psychologists, and educational practitioners interested in the link between brain sciences and education.
