Enumerative Invariants in Algebraic Geometry and String Theory : Lectures given at the C.I.M.E. Summer School held in Cetraro, Italy June 6–11, 2005
Starting in the middle of the 80s, there has been a growing and fruitful interaction between algebraic geometry and certain areas of theoretical high-energy physics, especially the various versions of string theory. Physical heuristics have provided inspiration for new mathematical definitions (such as that of Gromov-Witten invariants) leading in turn to the solution of problems in enumerative geometry. Conversely, the availability of mathematically rigorous definitions and theorems has benefited the physics research by providing the required evidence in fields where experimental testing seems problematic. The aim of this volume, a result of the CIME Summer School held in Cetraro, Italy, in 2005, is to cover part of the most recent and interesting findings in this subject.
Entry Inhibitors in HIV Therapy
The introductory chapters of this book present an overview of entry inhibitors, review current knowledge of how Env mediates entry, and discuss the challenge of genetic diversity in this region of the viral genome. Subsequent chapters feature current information on individual classes of entry inhibitors that target each step of the virus entry pathway, from attachment to membrane fusion. There is an emphasis on the complex determinants of entry inhibitor susceptibility, resistance mechanisms, the need for clinical phenotyping, and how these issues create new challenges for antiretroviral therapy. Encouraging pre-clinical studies of entry inhibitors as microbicidesare also discussed. The final chapters highlight the current status of entry inhibitors in clinical studies, the major milestone achieved with FDA approval of enfuvirtide, and review drug development, past and present.
Entropy, Search, Complexity
The present volume is a collection of survey papers in the fields of entropy, search and complexity. They summarize the latest developments in their respective areas.More than half of the papers belong to search theory which lies on the borderline of mathematics and computer science, information theory and combinatorics, respectively. Search theory has variegated applications, among others in bioinformatics. Some of these papers also have links to linear statistics and communicational complexity.
Entropy Methods for the Boltzmann Equation : Lectures from a Special Semester at the Centre Émile Borel, Institut H. Poincaré, Paris, 2001
Entropy and entropy production have recently become mathematical tools for kinetic and hydrodynamic limits, when deriving the macroscopic behaviour of systems from the interaction dynamics of their many microscopic elementary constituents at the atomic or molecular level. During a special semester on Hydrodynamic Limits at the Centre Émile Borel in Paris, 2001 two of the research courses were held by C. Villani and F. Rezakhanlou. Both illustrate the major role of entropy and entropy production in a mutual and complementary manner and have been written up and updated for joint publication. Villani describes the mathematical theory of convergence to equilibrium for the Boltzmann equation and its relation to various problems and fields, including information theory, logarithmic Sobolev inequalities and fluid mechanics. Rezakhanlou discusses four conjectures for the kinetic behaviour of the hard sphere models and formulates four stochastic variations of this model, also reviewing known results for these.
Entropy and Energy : A Universal Competition
Entropy and Energy- a Universal Competition" is a students textbook as well as a scientific monograph. The concepts of entropy and energy embody the effects of random walk in a body and of deterministic strife respectively, and are therefore often in competition. The book gives instructive examples from elementary thermodynamics and physico-chemistry and extrapolates the notion to non-standard thermodynamic subjects like shape memory, dissipation of the earth's atmosphere, and sociology
Entrepreneurship, the new economy and public policy : Schumpeterian perspectives
Silicon Valley is the most salient example of high-tech industrial clusters. Public policy makers throughout the world would like to learn the secrets of Silicon Valley in order to build their own high-tech economies. The existing literature on ind- trial clusters, which traces back to Marshall (1920), focuses on the way in which ?rms bene?t from locating in a cluster; it suggests that once a cluster comes into existence However, a more important question is how to reach this critical mass in the ?rst place. In contrast to the literature, evidence suggests that entrepreneurs rarely move when they est- lish high-tech start-ups. This contradicts the notion that location choice analyses lead entrepreneurs to a high-tech cluster. A high-tech industrial cluster such as Silicon Valley is characterized by c- centrated entrepreneurship.
Entrepreneurship, Growth, and Innovation : The Dynamics of Firms and Industries
This book is recommendable reading for all those scholars and students who want to become more familiar with recent theoretical advances and empirical results in the economics of entrepreneurship, innovation, and economic growth.
Entrepreneurship Policy : Theory and Practice
Entrepreneurship Policy: Theory and Practice is the first book to fully analyze the construction of entrepreneurship policy, a rapidly-evolving area of policy about which little is known. From a study and assessment of the practices of governments in thirteen countries in Europe, North America and the Asia-Pacific region, this book fully describes the policy area and shares new tools and methods for better understanding and explaining the how and why of an entrepreneurship policy approach. Methods of note include the entrepreneurship policy comprehensiveness index and the context method. It presents a conceptual model describing the many factors which affect, in a dynamic way, the level of entrepreneurship in a country or region. It also describes a typology of entrepreneurship policy which will be useful to others in categorizing their policy approaches.
Entrepreneurship in the U.S. : The Future is Now
This important book enhances understanding of entrepreneurial dynamics, providing the first analysis of changes in US entrepreneurial activity. It examines adult participation in new firm creation and differences in regional firm creation activity.
Entrepreneurship in the Region
The articles in this book provide strong evidence for the importance of regional factors that shape entrepreneurship and new firm formation processes. It is shown that regional differences of start-up rates and entrepreneurial attitudes are not at all elusive but tend to be rather persistent and prevail over longer periods of time. The evidence clearly suggests that the regional level can be an appropriate starting point for entrepreneurship policy and that research on the issue may considerably benefit from properly accounting for the spatial dimension.
Entrepreneurship in Emerging Domestic Markets : Barriers and Innovation
As one examines worldwide economic growth over the past decade, it is clear that the U.S. economy has surpassed most of the industrialized world, both in its rate of growth and its ability to create wealth. Entrepreneurship is critical to this growth—entrepreneurs recognize the potential of new ideas, design applications, develop new products, and successfully bring products to market. They build companies and create jobs, generating new opportunities for wealth creation.
Entrepreneurship and innovation education : Frameworks and tools
This book is a compilation of tools, techniques and frameworks for use in the field of entrepreneurship and innovation (E&I) education. Developed and honed over the past two decades, these teaching approaches are combined with well-versed practical insight. As professors know all too well, the human brain cannot articulate more than three or four dimensions of a problem without the aid of what could be referred to as checklists for thinking: frameworks (visual or otherwise) that help students think in terms of multiple variables affecting a problem.
Entrepreneurship and innovation : Theory, practice and context, 4th
Provides an overview of the theory, Practice and context of entrepreneurship and innovation at both the industry and firm level. It provides a foundation of ideas and understandings designed to shape the reader’s thinking and behaviour to better appreciate the role of innovation and entrepreneurship in modern economies, And to recognise their own abilities in this regard. The book provides the reader with an overview of these elements and how they combine to create new value in the market.
Entrepreneurship and Business : A Regional Perspective
This book examines the relationship between entrepreneurship, growth and regional aspects of business. The text offers two broad perspectives of entrepreneurship, a historical one and a comparative perspective. In the historical part, several examples of the co-operation between regional aspects and aspects of entrepreneurship are presented. The second part shows different aspects of entrepreneurship in a more and more globalizing world. Networking, the relationship between clusters and business innovation, economic transition and the links between social capital and business competitiveness are some of the topics.

Entrepreneurship : Concepts, Theory and Perspective
Entrepreneurship can, at times, seem like a veritable jungle where finding one's way can prove to be difficult. This book functions as a map locating the most important issues: those where an acceptable consensus already exists, and those that remain open to discussion.
Entrepreneurial Strategy : Starting, Managing, and Scaling New Ventures
This book focuses on explaining differences amongst organizations regarding various attributes, forms, and outcomes. By focusing on the “how” of new venture creation and management to produce well-established organizations, the authors aim to increase our understanding of the antecedents of most management research assumptions. New ventures are the source of most newly created jobs generated in an economy, new industries and markets, innovative products and services, and new solutions to economic, social, and environmental problems. However, most management research assumes a well-established organization as the starting point of their theorizing.
Entrepreneurial responses to chronic adversity : The bright, the dark, and the in between
Extends recent work on entrepreneurship in response to adverse events to explore entrepreneurial responses by people who face chronic adversity more deeply. Instead of focusing on the sort of responses intended to destroy the institutions that create and sustain chronic adversity, the authors are interested in how individuals use entrepreneurial action to find a way within these adverse constraints to improve their lives. They explore the positive outcomes arising from these entrepreneurial actions for the entrepreneurial actor and their family members as well as the negative consequences of these entrepreneurial responses to chronic adversity — outcomes that diminish others’ well-being.
Entrepreneurial Orientation in Academia
In addition to research and education, today’s role of acadamia in the United States also includes the creation of wealth for society. Universities are active in fostering innovation and transferring technology. However, it should be noted that some universities act more as entrepreneurs than others and are more successful in selling licenses and spinning off companies. Based on the concept of entrepreneurial orientation, Jan Boehm elaborates on the relationship between dimensions of entrepreneurial orientation – such as autonomy, innovativeness, proactiveness, competitiveness, risk-taking, and interdisciplinarity – and technology transfer performance of U.S. universities. Using variance-based multivariate analysis and a survey of principal investigators, the author concludes that entrepreneurial orientation within research organizations has a positive impact on technology transfer.
Entrepreneurial cognition : Exploring the mindset of entrepreneurs
This open access book investigates the inter-relationship between the mind and a potential opportunity to explore the psychology of entrepreneurship. Building on recent research, this book offers a broad scope investigation of the different aspects of what goes on in the mind of the (potential) entrepreneur as he or she considers the pursuit of a potential opportunity, the creation of a new organization, and/or the selection of an entrepreneurial career. This book focuses on individuals as the level of analysis and explores the impact of the organization and the environment only inasmuch as they impact the individual’s cognitions. Readers will learn why some individuals and managers are able to able to identify and successfully act upon opportunities in uncertain environments while others are not. This book applies a cognitive lens to understand individuals’ knowledge, motivation, attention, identity, and emotions in the entrepreneurial process.
