Abstract

Over the last decades, assessment of heart rate variability (HRV) has increased in various fields of research. HRV describes changes in heartbeat intervals, which are caused by autonomic neural regulation, i.e. by the interplay of the sympathetic and the parasympathetic nervous systems. The most frequent application of HRV is connected to cardiological issues, most importantly to the monitoring of post-myocardial infarction patients and the prediction of sudden cardiac death. Analysis of HRV is also frequently applied in relation to diabetes, renal failure, neurological and psychiatric conditions, sleep disorders, psychological phenomena such as stress, as well as drug and addiction research including alcohol and smoking. The widespread application of HRV measurements is based on the fact that they are noninvasive, easy to perform, and in general reproducible – if carried out under standardized conditions. However, the amount of parameters to be analysed is still rising. Well-established time domain and frequency domain parameters are discussed controversially when it comes to their physiological interpretation and their psychometric properties like reliability and validity, and the sensitivity to cardiovascular properties of the variety of parameters seems to be a topic for further research. Recently introduced parameters like pNNxx and new dynamic methods such as approximate entropy and detrended fluctuation analysis offer new potentials and warrant standardization. However, HRV is significantly associated with average heart rate (HR) and one can conclude that HRV actually provides information on two quantities, i.e. on HR and its variability. It is hard to determine which of these two plays a principal role in the clinical value of HRV. The association between HRV and HR is not only a physiological phenomenon but also a mathematical one which is due to non-linear (mathematical) relationship between RR interval and HR. If one normalizes HRV to its average RR interval, one may get ‘pure’ variability free from the mathematical bias. Recently, a new modification method of the association between HRV and HR has been developed which enables us to completely remove the HRV dependence on HR (even the physiological one), or conversely enhance this dependence. Such an approach allows us to explore the HR contribution to the clinical significance of HRV, i.e. whether HR or its variability plays a main role in the HRV clinical value. This Research Topic covers recent advances in the application of HRV, methodological issues, basic underlying mechanisms as well as all aspects of the interaction between HRV and HR.

Abstract

In January 1995, four Latin American countries, Argentina, Brazil, Uruguay and Paraguay joined their destinies within a common and ambitious enterprise called MERCOSUR. MERCOSUR, the Common Market of the South, represents an important economic integration area that generates a GDP of $US 600 billion, providing a market of 200 million people spread over an area of 12 million square km. Initially, MERCOSUR performance has been more than successful, as intra-MERCOSUR trade has increased significantly. However, the elimination of intra-MERCOSUR tariffs will not be efficient if at the same time the sharp variability of nominal exchange rates artificially affects the relative prices of different products. The question as to the choice of the optimal exchange rate system to be adopted among MERCOSUR countries becomes critical if MERCOSUR states attempt to go further along the path of increasing their trade flows of goods and services. The study contributes to filling this gap by providing some alternative answers to this issue. The analysis has been based on three pillars: a theoretical review of exchange rate systems; a review of the European experience; and an analysis of the Latin American experience.

Abstract

Which cultural concepts of family life exist in Germany? What is considered "normal", "desirable", and "deviant" and how do these ideas influence family formation and family life? These questions are the focus of the contributions collected in this volume, in which the diversity and contradictoriness of family models in Germany are identified. This book thus makes an important contribution to explaining the cultural understanding of demographic processes. Recommendations for future research and family policy are derived from the results of the study in order to better meet the needs of young people in Germany.

Abstract

This book pulls together papers presented at a conference in honour of the 1981 Nobel Prize Winner for Economic Science, the late James Tobin. Among the contributors are Olivier Blanchard, Edmund Phelps, Charles Goodhart and Marco Buti. One of the main aims of the conference was to discuss what potential role monetary policy has on economic activity and unemployment reduction in three key currency zones - the United States, European Union and Japan.

Abstract

This book explores the perceived paradigmatic conflict within British classical economics between the so called 'Ricardo School' and the contemporary French Economics of Jean-Baptiste Say. Samuel Hollander provides the reader with extensive evidence, utilizing all editions of Say's main texts and his lesser-known writings in order to demonstrate his adherence to much of Ricardian theory. This intriguing book focuses on selected doctorinal issues and surrounding debates, and will interest all serious historians of economic thought, finding a place on the bookshelves of many economists across the world.

Abstract

Institutional Frameworks and Labor Market Performance produces an in-depth analysis of the functioning of various labor market institutions in both the USA and Germany. Particular emphasis is given to the substantial differences between the US and Germany in the ways important areas are regulated. The authors show that the impact of institutions on economic performance is ambivalent. They argue that in this sense, the decision is not one between regulation and deregulation but rather one between different degrees and forms of regulation.

Abstract

To date, critical analysis of the EMU project has largely been advanced from the centre-right spectrum of British politics. Comparable questions from the centre-left have failed to find a coherent voice. Although, the European fault-line cannot be characterized as a neat Left-Right issue there are noticeable divisions in opinion across British business, the trade union movement and within the Labour Party. Offering a unique insight into this key debate from the ‘centre-left’, eurosceptic view point, this book provides a rigorous analysis of all the salient economic and political issues of concern, such as: * the economics of a single currency * employment and social implications * sovereignty * political determination. The arguments presented in this volume highlight the emergence of a coherent alternative to deepening economic integration as a platform to build a just and equitable society. Contributions are drawn from leading academics, trade union leaders and prominent politicians, both from the Labour Party and the wider progressive Left in British politics. This informative and thought provoking book will be indispensable reading for students and practitioners in economics, politics and international relations, as well as those interested in this highly contentious topic.
