Sociolinguistics (57,311 Books)


It is the study of the effect of any and all aspects of society, including cultural norms, expectations, and context, on the way language is used, and the effects of language use on society. Sociolinguistics differs from sociology of language in that the focus of sociolinguistics is the effect of the society on the language, while the latter's focus is on the language's effect on the society. Sociolinguistics overlaps to a considerable degree with pragmatics. It is historically closely related to linguistic anthropology and the distinction between the two fields has even been questioned recently.

1. INTRODUCTION Immunity results from many complex interacting mechanisms. The skin and mucous membranes are nonspecific barriers to infection and there are numerous other nonspecific factors such as lactoferrin and interferon. Furthermore, yet other nonspecific factors act in conjunction with specific immunity mechanisms ; the complement system and phagocytic cells are prime examples of these factors. Deficiency of an immunity mechanism may involve a specific factor, su...

The Tunnel Profile

Technical Reference Publication

Introduction: Many Metropolitan Area Networks (MANs) and some Local Area Networks (LANs) have a ring topology, as the fibre runs. The Ethernet Automatic Protection Switching (EAPS) technology described here works well in ring topologies for MANs or LANs. Most MAN operators want to minimise the recovery time in the event that a fibre cut occurs. The Ethernet Automatic Protection Switching (EAPS) technology described here converges in less than one second, often in less th...

INTRODUCTION The control of American and African trypanosomiasis involves considerable difficulties, particularly the continental dimensions of the problem, the large numbers of people exposed to the risk of infection, and the lack of a single inexpensive method of mass control that is effective in all epidemiological conditions. The areas principally affected by the diseases are the developing countries, which are unable to use some of the measures that have been develo...

1. INTRODUCTION There is no doubt that one of the hallmarks of the twentieth century is the increase in human life-span, in both industrialized and developing countries. This increase is due to several factors: for example better clinical and pharmacological control of infectious diseases, better sanitation, and improved nutrition. However, such a large demographic change-in the last 80 years the life expectancy in industrialized countries has increased by 5096, resultin...

By: Florentin Smarandache; Jean Dezert

This book is devoted to an emerging branch of Information Fusion based on new approach for modeling the fusion problematic when the information provided by the sources is both uncertain and (highly) conflicting. This approach, known in literature as DSmT (standing for Dezert-Smarandache Theory), proposes new useful rules of combinations. We gathered in this volume a presentation of DSmT from the beginning to the latest development. Part 1 of this book presents the curren...
