Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

This book (hardcover) is part of the TREDITION CLASSICS. It contains classical literature works from over two thousand years. Most of these titles have been out of print and off the bookstore shelves for decades. The book series is intended to preserve the cultural legacy and to promote the timeless works of classical literature. Readers of a TREDITION CLASSICS book support the mission to save many of the amazing works of world literature from oblivion. With this series, tredition intends to make thousands of international literature classics available in printed format again - worldwide.

Our book is devoted to the topological fixed point theory both for single-valued and multivalued mappings in locally convex spaces, including its application to boundary value problems for ordinary differential equations (inclusions) and to (multivalued) dynamical systems. It is the first monograph dealing with the topo- logical fixed point theory in non-metric spaces. Although the theoretical material was tendentially selected with respect to ap- plications, we wished to have a self-consistent text (see the scheme below). There- fore, we supplied three appendices concerning almost-periodic and derivo-periodic single-valued {multivalued) functions and (multivalued) fractals. The last topic which is quite new can be also regarded as a contribution to the fixed point theory in hyperspaces. Nevertheless, the reader is assumed to be at least partly famil- iar in some related sections with the notions like the Bochner integral, the Au- mann multivalued integral, the Arzela-Ascoli lemma, the Gronwall inequality, the Brouwer degree, the Leray-Schauder degree, the topological (covering) dimension, the elemens of homological algebra, ...Otherwise, one can use the recommended literature. Hence, in Chapter I, the topological and analytical background is built. Then, in Chapter II (and partly already in Chapter I), topological principles necessary for applications are developed, namely: the fixed point index theory (resp. the topological degree theory), the Lefschetz and the Nielsen theories both in absolute and relative cases, periodic point theorems, topological essentiality, continuation-type theorems.

, Jean ANDRE Universite de Paris XI, ORSAY, France. Sperm cells have long been considered as the most highly specialized of all living cells. They surely are, being very diverse, very complex, containing organelles which do not exist in any other cell -such as acrosome or crystallized mitochondria- and being endowed with a very unique behaviour, that is to meet and recognize the ovum, pierce its protective envelopes and inject into its cytoplasm a most precious deposit, the haploid genome of the species. It is Baccio Baccetti's merit to have felt the need for a confrontation of the scientists working on sperm in order to clarify the apparent complexity of the enormous amount of knowledge accumulated on the subject. Thus, he successfully inaugurated the series of the InternationaZ Symposia on SpermatoZogy. The Seillac edition is the fourth in the series. After an initial stage during which morphology was predominant, our meetings have turned more and more towards function. It has been the will of the French Organizing Committee to devote this meeting mainly to Eutherians, and, among those, to man, in connection with the conflicting necessities to help the sterile couples and to contrul the population explosion at the surface of the world.

This practical, industry-oriented reference starts with the basic concepts and principles behind Total Quality Management. The author then presents examples of Quality Assurance (QA) programs that can be applied to the food industry using simple, proven formats. He provides readers with an overall understanding of quality assurance programs and the practical knowledge necessary to set up a program. The book discusses the role of QA in product manufacturing, stressing the need for interactions between QA, Qualtiy Control, product development, marketing, sales, and consumer Affairs.

The Routledge Handbook of Tourism Cities presents an up-to-date, critical and comprehensive overview of established and emerging themes in urban tourism and tourist cities. Offering socio-cultural perspectives and multidisciplinary insights from leading scholars, the book explores contemporary issues, challenges and trends. Organised into four parts, the handbook begins with an introductory section that explores contemporary issues, challenges and trends that tourism cities face today. A range of topics are explored, including sustainable urban tourism, overtourism and urbanisation, the impact of terrorism, visitor-host interactions, as well as reflections on present and future challenges for tourism cities. In Part II the marketing, branding and markets for tourism cities are considered, exploring topics such as destination marketing and branding, business travellers and exhibition hosting. This section combines academic scholarship with real-life practice and case studies from cities. Part III discusses product and technology developments for tourism cities, examining their supply and impact on different travellers, from open-air markets to creative waterfronts, from social media to smart cities. The final Part offers examples of how urban tourism is developing in different parts of the world and how worldwide tourism cities are adapting to the challenges ahead. It also explores emerging forms of specialist tourism, including geology and ecology-based tourism, socialist heritage and post-communist destination tourism. This handbook fills a notable gap by offering a critical and detailed understanding of the diverse elements of the tourist experience today. It contains useful suggestions for practitioners, as well as examples for theoretical frameworks to students in the fields of urban tourism and tourism cities. The handbook will be of interest to scholars and students working in urban tourism, heritage studies, human geography, urban studies and urban planning, sociology, psychology and business studies.

This monograph provides a novel approach to the evaluation of economic policy by combining two different analytical strategies. On the one hand, the computable general equilibrium (CGE) analysis, a standard tool mostly used to quantify the impact of economic measures or changes in the structural data of the economy. On the other hand, the multiple criteria decision-making (MCDM) approach, an op- misation technique that deals with problems with more than one objective. Ty- cally, CGE is well suited for the analysis of the interactions of multiple agents from the point of view of a planner single objective. Combining this technique with the MCDM approach allows developing models in which we ?nd many interacting agents and a decision maker with several objectives. The contribution of this work is partly methodological and partly applied. It provides a framework for the analysis of this type of problems, as well as a series of applications in which the strength of the approach is made clear. The consideration of environmental problems, as a speci?c ?eld in which this technique of analysis can be used, is particularly well chosen. The environmental concern keeps growing steadily and has already become an issue in most of the standard economic decisions. It is therefore extremely important to ?nd systematic ways to introduce such a concern in the models with which we evaluate the impact of policy measures.

Learn from Kids, Peers, and the World to Transform Professional Learning What can kids teach us about educational practices? It turns out, plenty. PD is evolving into professional learning (PL), where personalized experiences focus on goals and outcomes, rather than seat time. In Evolving Learner, successful PL is framed through three critical sources: learning from kids, from peers, and from the world. Woven throughout the book are tangible connections to cycles of inquiry where a harmonious balance is the ultimate goal when students are engaged in inquiry for deeper learning and teachers are engaged in a parallel process to improve their practice. The authors' unique framework shifts away from factory model "PD" and transforms it into experiences tailored to kids' and adult learners' specific needs. Clear strategies for accomplishing PL are presented through A framework where both students and teachers are active agents of learning Cycles of inquiry to empower students to become the owners of learning Techniques to make thinking visible for teachers and students Cutting edge coverage of applying technology to professional learning including the use of social media, gamification, and digital badges The time is right to reclaim ownership of your professional learning: Evolving Learner is an essential guide for embarking on this journey.
