Anyone who has experience with a car, bicycle, motorcycle, or train knows that the dynamic behavior of different types of vehicles and even different vehicles of the same class varies significantly. For example, stability (or instability) is one of the most intriguing and mysterious aspects of vehicle dynamics. Why do some motorcycles sometimes exh
The positive versus negative distinction of schizophrenic disorders has pro moted ongoing research. Phenomenology, psychopathology, biology, genet ics, pharmacological and nonpharmacological treatment, psychosocial and longitudinal research: all have found a new focus of interest. This volume attempts to provide an unbiased picture of the status of American and Eu ropean knowledge regarding the positive/negative distinction. Researchers from North America and Europe describe the relation of modern concepts of positive and negative symptomatology to the original models of Rey nolds and Jackson. Integrating phenomenological, genetic, and biological factors, the authors depict current methods of assessing positive and nega tive symptomatology, differentiating between primary and secondary symp tomatology, and using pharmacological and nonpharmacological treatment. The stability of positive and negative symptoms over time and evidence for the occurrence of separate positive and negative episodes over a long-term course of schizophrenia are extensively discussed in terms of their implica tions on the positive/negative construct. The relevance of the positive/nega tive dichotomy to child and adolescent schizophrenia is also debated. The main aim of this book is not to advocate a single concept and present only arguments supporting it, but to discuss important controversies. Prob lems concerning a concept cannot be solved by ignoring them. However, unanswered questions may be resolved through discussion, debate, and con structive compromise.

This volume represents an overview of some recent developments on the absolute stability of nonlinear systems. The contents are divided into six chapters - chapter 1 introduces the main tools and the principal results used in this text, such as Liapunov functions, K-class functions, Dini-derivatives, M-matrices and the principal theorems on global stability.
Many people grow up with at least one sibling. These siblings are often ‘fellow travellers’ through adversity or significant life events; they can act as a source of support for some children while a source of conflict for others. For these reasons, siblings are a potentially powerful influence on development and this book is one of the first of its kind to provide an overview of cutting-edge psychological research on this important relationship. Why Siblings Matter is a cornerstone text on siblinghood. Integrating findings from a 10 year longitudinal study alongside wider research, it provides a lifespan perspective examining the impact of sibling relationships on children’s development and well-being. This text situates siblings in their historical, developmental and family context, considers the influence of siblings on children’s development and adjustment, and provides an introduction to new research on siblings in diverse contexts. The authors discuss sibling relationships in varied populations such as siblings with disabilities, siblings in different cultures and siblings in non-traditional families, while also considering the practical implications of research. Covering both classical studies and new results this book offers take-home messages for promoting positive sibling interactions. It will be invaluable reading for students and researchers in developmental psychology and family studies and professionals in education, health and social work.
