Linear Optimization Problems with Inexact Data
Linear programming attracted the interest of mathematicians during and after World War II when the first computers were constructed and methods for solving large linear programming problems were sought in connection with specific practical problems—for example, providing logistical support for the U.S. Armed Forces or modeling national economies. Early attempts to apply linear programming methods to solve practical problems failed to satisfy expectations. There were various reasons for the failure. One of them, which is the central topic of this book, was the inexactness of the data used to create the models. This phenomenon, inherent in most pratical problems, has been dealt with in several ways. At first, linear programming models used "average” values of inherently vague coefficients, but the optimal solutions of these models were not always optimal for the original problem itself. Later researchers developed the stochastic linear programming approach, but this too has its limitations. Recently, interest has been given to linear programming problems with data given as intervals, convex sets and/or fuzzy sets. The individual results of these studies have been promising, but the literature has not presented a unified theory. Linear Optimization Problems with Inexact Data attempts to present a comprehensive treatment of linear optimization with inexact data, summarizing existing results and presenting new ones within a unifying framework.
Linear Models for Optimal Test Design
Begins with a reflection on the history of test design--the core activity of all educational and psychological testing. It then presents a standard language for modeling test design problems as instances of multi-objective constrained optimization. The main portion of the book discusses test design models for a large variety of problems from the daily practice of testing, and illustrates their use with the help of numerous empirical examples. The presentation includes models for the assembly of tests to an absolute or relative target for their information functions, classical test assembly, test equating problems, item matching, test splitting, simultaneous assembly of multiple tests, tests with item sets, multidimensional tests, and adaptive test assembly. Two separate chapters are devoted to the questions of how to design item banks for optimal support of programs with fixed and adaptive tests. Linear Models for Optimal Test Design, which does not require any specific mathematical background, has been written to be a helpful resource on the desk of any test specialist.
Limits to the European Union’s Normative Power in a Post-conflict Society : EULEX and Peacebuilding in Kosovo
Investigates the EU’s peacebuilding activities in that country, in the light of the normative power theory in the post-conflict setting and peacebuilding theory. Ten years after the massive engagement of the EU in the country torn by war, the authors critically assess the effects of the EU projecting its normative power – the enforcement of its standards, ‘good’ or ‘bad’ – through the EULEX mission, taking into consideration also the local aspects, so far neglected in this field of research. Inspecting thoroughly the EULEX activities in the police, customs and judiciary sector.This open access book offers a comprehensive assessment of the EULEX mission, based on two Horizon2020 research projects: IECEU - Improving the Effectiveness of Capabilities in EU Conflict Prevention, and KOSNORTH – The European Union and its Normative Power in a Post-conflict Society: A Case Study of Northern Kosovo (Marie Sklodowska-Curie Individual Fellowship).
Lifelong Learning : Interpretations of an Education Policy in Europe
In Europe, the idea of Lifelong Learning has developed from an education policy to the most important pedagogic paradigm. The concept was created as an answer to the international education crisis, diagnozed by Philip H. Coombs in 1967. Since the European Year of Lifelong Learning in 1996, it has been regarded as an alternative to deal with the rapid social, political and economic changes of the modern world. Andrea Óhidy shows the genesis of the concept and its development towards a pedagogic paradigm. She investigates the relations between the concept of Lifelong Learning and school education and points out the most important links between Lifelong Learning and adult education.
Lifelong Learning - Signs, Discourses, Practices
This text explores the different ways in which the various social practices in which people participate becomes signed as learning, how and why that occurs and with what consequences. It takes seriously the linguistic turn in social theory to draw upon semiotics and poststructuralism through which to explore the significance of lifelong learning as an emerging discourse in education. The text explores the different ways in which learning conveys meaning and is given meaning. Given this, lifelong learning therefore is a way, and a significant way, in which learning is fashioned. The text then explores the notion that, if learning is lifelong and lifewide, what precisely is learning as distinct from other social practices and how those practices are given meaning as learning.
Life Conduct in Modern Times : Karl Jaspers and Psychoanalysis
This award-winning book investigates the critique of psychoanalysis formulated by the psychiatrist and philosopher Karl Jaspers (1883-1969) over a period of five decades. His arguments against Freud and his followers are examined from systematic perspectives. The study traces the medico-historical roots of Jasper’s criticism of psychoanalysis and then places it within the framework of scientific theory before devoting itself extensively to medico-ethical aspects of the controversy, which are ultimately treated in terms of a history of mentalities. According to this view, Jasper’s student Hannah Arendt saw to it that the philosopher be made aware of the socio-cultural impact which psychoanalysis was beginning to have in the U.S.A.
Lie theory ; Vol.230 : Harmonic analysis on symmetric spaces, general Plancherel theorems
Van den Ban’s introductory chapter explains the basic setup of a reductive symmetric space along with a careful study of the structure theory, particularly for the ring of invariant differential operators for the relevant class of parabolic subgroups. Advanced topics for the formulation and understanding of the proof are covered, including Eisenstein integrals, regularity theorems, Maass–Selberg relations, and residue calculus for root systems. Schlichtkrull provides a cogent account of the basic ingredients in the harmonic analysis on a symmetric space through the explanation and definition of the Paley–Wiener theorem. Approaching the Plancherel theorem through an alternative viewpoint, the Schwartz space, Delorme bases his discussion and proof on asymptotic expansions of eigenfunctions and the theory of intertwining integrals.

This edited volume reviews his work and assesses its influence in the social sciences, notably his work on arms races and their consequences, mathematical models, the size distribution of wars, and geographical features of conflict
Leibniz and the English-Speaking World
These essays comprise a first attempt to assess overall the attention awarded to Leibniz’s philosophy in the English-speaking world in his own time and up to the present day. In addition to an introductory overview there are fourteen original and previously unpublished essays considering Leibniz’s connections with his English-speaking contemporaries and near contemporaries as well as the later reception of his thought in Anglo-American philosophy.
Lectures on Quantum Gravity
A primary goal was to foster interaction and communication between participants from different cultures, both in the layman’s sense of the term and in terms of approaches to quantum gravity. We hope that the links formed by students and the school will persist throughout their professional lives, continuing to promote interaction and the essential exchange of ideas that drives research forward. This volume contains improved and updated versions of the lectures given at the School. It has been prepared both as a reminder for the participants, and so that these pedagogical introductions can be made available to others who were unable to attend. We expect them to serve students of all ages well.
Lead-free Soldering
The push toward lead-free soldering in computers, cell phones and other electronic and electrical devices has taken on a greater urgency as laws have been passed or are pending in the United States, the European Union and Asia which ban lead-bearing solder. These new restrictions on hazardous substances are changing the way electronic devices are assembled, and specifically affect process engineering, manufacturing and quality assurance. Lead-Free Soldering offers in a single volume a broad collection of practical techniques for lead-free soldering design and manufacture, which up to now have been scattered in difficult-to-find scholarly sources. The book includes the latest information on proposed changes to lead-free standards, and up-to-date analysis of government and legislative activities and regulations in North America, Europe and Asia.
Lead-Free Electronic Solders : A Special Issue of the Journal of Materials Science : Materials in Electronics
In the last few decades the effect of lead contamination on human health has received significant attention. Based on such concerns, elimination of lead from ceramic glaze, paint, plumbing etc. has been legislated and implemented. However, until recently, solders used in electronics, based on suitability and knowledge-base developed over a long period of time, remained lead-based. Successive rapid advances in microelectronic devices in recent decades make them obsolete within a very short period after their introduction resulting in significant quantities of electronic wastes in landfills. Leaching of toxic lead from such electronic wastes can result in contamination of the human food chain causing serious health hazards. As a consequence, several European and Pacific Rim countries have passed legislations warranting elimination of lead from electronic solders by fast approaching deadlines. Global economic pressures brought on by such legislations have resulted in a flurry of research activities to find suitable lead-free substitutes for the traditional leaded electronic solders.

Lattices and Ordered Algebraic Structures
Lattices and Ordered Algebraic Structures provides a lucid and concise introduction to the basic results concerning the notion of an order. Although as a whole it is mainly intended for beginning postgraduates, the prerequisities are minimal and selected parts can profitably be used to broaden the horizon of the advanced undergraduate. The treatment is modern, with a slant towards recent developments in the theory of residuated lattices and ordered regular semigroups.
Latinas/os in the United States : Changing the Face of América
This book also addresses important theoretical and methodological issues related to the study of Latinas/os and presents in-depth analyses (both quantitative and qualitative) of substantive issues relevant to this population, including migration, demographic patterns and processes, education, health, citizenship, political participation, religion, gender and sex roles, literary and cultural production, and the media. The authors seek to educate and increase awareness of the diversity that exists among the Latina/o population, and to carefully examine the social, economic, demographic, cultural, and political impacts and contributions that this growing population has had in the United States. The edited volume presents a holistic and multidisciplinary perspective of this group, and it critically documents how Latinas and Latinos have changed and will continue to change the face of América.
Large-Scale Cognitive Assessment : Analyzing PIAAC Data
Summarises existing analysing techniques using data from PIAAC, a study initiated by the OECD that assesses key cognitive and occupational skills of the adult population in more than 40 countries. The approximately 65 PIAAC datasets that has been published worldwide to date has been widely received and used by an interdisciplinary research community
Language, Expressivity and Cognition
The book presents how language shapes communicative and cognitive processes but at the same time is also shaped by those processes. The chapters put forward a number of disciplinary and methodological perspectives encompassing insights from cognitive and social psychology, (critical) discourse analysis, cognitive linguistics, corpus linguistics and sociolinguistics. Both intralingual as well as contrastive, each chapter also engages with qualitative and quantitative methods.
Landscape Analysis and Visualisation : Spatial Models for Natural Resource Management and Planning
This book presents a collection and synthesis of many of these perspectives — perhaps it could only be produced in a land urb- ised in the tiniest of pockets, and yet so daunting with respect to the way non-populated landscapes dwarf its cities. Many travel to Australia to its cities and never see the landscapes — but it is these that give the country its power and imagery. It is the landscapes that so impress on us the need to consider how our intervention, through activities ranging from resource exploitation and settled agriculture to climate change, poses one of the greatest crises facing the modern world. In this sense, Australia and its landscape provide a mirror through which we can glimpse the extent to which our intervention in the world threatens its very existence.
Lake Victoria : Ecology, Resources, Environment
Recently, there has been, and continues to be, a tremendous interest on Lake Victoria and its environs, both locally and internationally. A casual browsing on the Internet indicates that the entries on the Lake have been rising phenomenally. At the same time, the issues discussed are as diverse as they are varied in their treatment of the subject, both in terms of depth and comprehensiveness. The information on Lake Victoria and its environ is scattered, isolated, and sometimes confusing even though documentation on the subject are available. Despite this situation, the fact remains that various people (e. g. , secondary and universitystudents,researchers,practitioners,etc. ,)wouldliketoaccess and know more about the Lake and its environs. Aware of the existing information gap about this world’s second largest fresh water Lake, this book is intended to provide readers with up-to-date information pertaining the Lake. The book gives an in-depth coverage of environmental issues, - source endowment, poverty amidst plenty, development opportunities, challenges and other related issues facing the Lake and its environs. It aims at providing information on the above variables, which hopefully will address the needs of various users.
