Immigrant entrepreneurs are known to be heterogeneous in terms of available resources and entrepreneurial outcomes. However, this heterogeneity, as well as immigrant entrepreneurs’ embeddedness in social networks and the institutional context of high-income welfare states such as Sweden, remains understudied. Sweden represents an interesting case as a popular immigration destination which liberalized its migration policy for entrepreneurs and changed other regulations, encouraging immigrant entrepreneurship after 2008. Theoretically, the dissertation contributes to the mixed embeddedness approach to immigrant entrepreneurship by considering three stages of the entrepreneurial process – entry, performance, and potential exit – in a changing institutional environment. Methodologically, the dissertation operationalizes the mixed embeddedness approach by studying these three stages – entry (propensity to start a business), performance (entrepreneurial incomes), and potential exit (duration in business) – among different categories of immigrants. Explanatory factors are drawn from three levels of analysis: institutional change (macro), social, ethnic and family networks (meso), and the individual’s human capital (micro). A range of statistical tools is used for empirical analyses: Difference-in-difference methods in combination with Coarsened Exact Matching and Oaxaca-Blinder decomposition are used to investigate the influence of institutional change on entrepreneurial entry and performance. Survival models based on Cox regression are applied to investigate the influence of social and family ties on the likelihood of entrepreneurial exit. A combination of clustering and association analysis allows heterogeneity to be approached via the categorization of immigrant entrepreneurs. Empirically, based on rich data from Swedish registers, the dissertation reveals that the propensity to start businesses in expanding ICT industries among labour immigrants was increased, and performance in terms of income among new immigrant entrepreneurs was improved after institutional change, compared to earlier. It also stresses that family networks mitigate a lack of other resources for refugee entrepreneurs, allowing them to stay in business longer. Two main categories of new immigrant entrepreneurs were distinguished in the overall heterogeneous population. The dissertation consists of four papers and an introductory chapter. Invandrarföretagare uppvisar stor heterogenitet när det gäller tillgängliga resurser och framgång i sitt företagande. Denna heterogenitet, liksom invandrarföretagens inbäddning i sociala nätverk och i den svenska välfärdsstatens institutionella kontext, är emellertid understuderad. Sverige utgör ett intressant fall eftersom det är ett land med relativt stor invandring som efter 2008 liberaliserade migrationspolitiken för företagare och på olika sätt uppmuntrade invandrares företagande. Teoretiskt bidrar avhandlingen till mixed embeddedness-perspektivet genom att analysera tre stadier i entreprenörsprocessen: uppstart, utveckling och eventuell avveckling, i förhållande till institutionell förändring. Mixed embeddedness operationaliseras i avhandlingen genom att olika kategorier invandrare studeras vid olika steg i entreprenörsprocessen; uppstart (benägenhet att starta ett företag), utveckling (företagarinkomster) samt eventuell avveckling (varaktighet i företaget) och genom att förklarande faktorer studeras på tre analysnivåer: institutionell förändring (makro), sociala, etniska och familjenätverk (meso) samt individens humankapital (mikro). En rad statistiska verktyg används för de empiriska analyserna; Difference-in-difference-metoder i kombination med Coarsened Exact Matching och Oaxaca-Blinder decomposition används för att undersöka hur institutionella förändringar påverkar uppstart och utveckling. Överlevnadsmodeller baserade på Cox-regression tillämpas för att undersöka hur sociala nätverk och familjeband påverkar sannolikheten för avveckling. Med en kombination av klusteranalys och associationsanalys undersöks mönster i heterogeniteten bland invandrarföretagarna genom kategorisering. Empiriskt, baserat på detaljerade data från svenska register, visar avhandlingen att benägenheten att starta verksamhet inom IKT-branschen ökade bland arbetskraftsinvandrare, samt att inkomsterna bland nya invandrarföretagare förbättrades efter en period av institutionell förändring. Avhandlingen visar även att familjenätverk motverkar bristen på andra resurser för företagare med flyktingbakgrund, vilket gör att de kan stanna i verksamheten längre. Två huvudkategorier går att urskilja i den heterogena gruppen av företagare. Avhandlingen är en sammanläggning av fyra artiklar och en inledande kappa.

This is the eBook of the printed book and may not include any media, website access codes, or print supplements that may come packaged with the bound book. The Principles and Practice of Cryptography and Network Security Stallings’ Cryptography and Network Security, Seventh Edition, introduces the reader to the compelling and evolving field of cryptography and network security. In an age of viruses and hackers, electronic eavesdropping, and electronic fraud on a global scale, security is paramount. The purpose of this book is to provide a practical survey of both the principles and practice of cryptography and network security. In the first part of the book, the basic issues to be addressed by a network security capability are explored by providing a tutorial and survey of cryptography and network security technology. The latter part of the book deals with the practice of network security: practical applications that have been implemented and are in use to provide network security. The Seventh Edition streamlines subject matter with new and updated material — including Sage, one of the most important features of the book. Sage is an open-source, multiplatform, freeware package that implements a very powerful, flexible, and easily learned mathematics and computer algebra system. It provides hands-on experience with cryptographic algorithms and supporting homework assignments. With Sage, the reader learns a powerful tool that can be used for virtually any mathematical application. The book also provides an unparalleled degree of support for the reader to ensure a successful learning experience.

The long-awaited new edition of NAEYC's book Developmentally Appropriate Practice in Early Childhood Programs is here, fully revised and updated! Since the first edition in 1987, it has been an essential resource for the early childhood education field. Early childhood educators have a professional responsibility to plan and implement intentional, developmentally appropriate learning experiences that promote the social and emotional development, physical development and health, cognitive development, and general learning competencies of each child served. But what is developmentally appropriate practice (DAP)? DAP is a framework designed to promote young children's optimal learning and development through a strengths-based approach to joyful, engaged learning. As educators make decisions to support each child's learning and development, they consider what they know about (1) commonality in children's development and learning, (2) each child as an individual (within the context of their family and community), and (3) everything discernible about the social and cultural contexts for each child, each educator, and the program as a whole. This latest edition of the book is fully revised to underscore the critical role social and cultural contexts play in child development and learning, including new research about implicit bias and teachers' own context and consideration of advances in neuroscience. Educators implement developmentally appropriate practice by recognizing the many assets all young children bring to the early learning program as individuals and as members of families and communities. They also develop an awareness of their own context. Building on each child's strengths, educators design and implement learning settings to help each child achieve their full potential across all domains of development and across all content areas.
