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.
Throughout the twentieth century, biologists investigated the mechanisms that stabilize biological populations, populations which--if unchecked by such agencies as competition and predation--should grow geometrically. How is order in nature maintained in the face of the seemingly disorderly struggle for existence? In this book, Laurence Mueller and Amitabh Joshi examine current theories of population stability and show how recent laboratory research on model populations--particularly blowflies, Tribolium, and Drosophila--contributes to our understanding of population dynamics and the evolution of stability. The authors review the general theory of population stability and critically analyze techniques for inferring whether a given population is in balance or not. They then show how rigorous empirical research can reveal both the proximal causes of stability (how populations are regulated and maintained at an equilibrium, including the relative roles of biotic and abiotic factors) and its ultimate, mostly evolutionary causes. In the process, they describe experimental studies on model systems that address the effects of age-structure, inbreeding, resource levels, and population structure on the stability and persistence of populations. The discussion incorporates the authors' own findings on the evolution of population stability in Drosophila. They go on to relate laboratory work to studies of animals in the wild and to develop a general framework for relating the life history and ecology of a species to its population dynamics. This accessible, finely written illustration of how carefully designed experiments can improve theory will have tremendous value for all ecologists and evolutionary biologists.
"As of late 2014, many American and Jordanian experts believe Jordan to be stable. Yet while Jordan is stable, it faces a range of existing and emerging challenges. These include chronic unemployment, sporadic political unrest, budget deficits, a water shortage, and geographically isolated yet troubling internal security concerns. The Syrian refugee crisis both exacerbates these challenges and offers opportunities to the government of Jordan. If the Syrian refugees remain relatively content and continue to assimilate into northern and central Jordan, they might directly benefit the Jordanian economy by stimulating growth. Donors and lenders have increased their support to Jordan, in turn offering the government an opportunity to improve the lives of both Syrian refugees and Jordanian citizens. Most important, Jordan benefits from what one expert terms negative stability: Jordanian citizens might be dissatisfied with many aspects of their government, but the chaos in neighboring states has thus far dissuaded Jordanians from pursuing civil or violent actions that might destabilize Jordan. Jordanians do not want their country to look like Syria, Iraq, or Egypt. Jordan is likely to undergo further and perhaps unforeseen challenges in 2015 and 2016, but it has the opportunity to alleviate many of its enduring challenges. If Jordan wisely invests forthcoming international refugee support, it has the opportunity to shift popular outlook from negative to positive--and more optimistic--stability. This report's analytic forecasts should help the United States determine how to support Jordan as it faces the Syrian refugee crisis"--Publisher's description.
This proceedings book presents outcomes of the Innovative Economic Symposium – 2020 organized by the Institute of Technology and Business in České Budějovice (VŠTE) in Russia in collaboration with two universities: Financial University under the Government of the Russian Federation (Moscow) and Samara State University of Economics (Samara). The symposium aims to bring together experts and young scientists in economy, management, international relations, finance, marketing, and professional education from Asian and European countries, to share knowledge and experience and discuss issues related to stable economic development, international business, entrepreneurship, Industry 4.0, cooperation between educational and business structures, strategic decision-making, and processes of economic globalization and fragmentation. The book consists of two parts corresponding to the thematic symposium areas. The book content covers two sections: stable development in unstable world and globalization and fragmentation forces of the current world economy. The main topics included in the book are as follows: - Where is the world moving to and where is the economy in it? - Institutionalization of innovations. - Network architecture of economic relations. - Competences for the future. - Smart change management. - Monetary and fiscal policy development as a factor of economic modernization. - Role of international trade in the economy globalization. - Impact of globalization and economic fragmentation on the enterprise’s internal environment. - Financial conditions for entrepreneurship under the economic modernization. - Impact of scientific and technological progress on globalization and fragmentation of the economy.
