Analysis of Cosmetic Products advises the reader from an analytical chemistry perspective on the choice of suitable analytical methods for production monitoring and quality control of cosmetic products. In the format of an easy-to-understand compendium of published literature on the subject, this book will enable people working in the cosmetic industry or in research laboratories to: * become familiar with the main legislative and analytical literature on this subject and * learn about and choose suitable analytical procedures for production monitoring and control of cosmetic products, according to their composition. The first section of Analysis of Cosmetic Products covers various definitions and concepts relating to cosmetic products, current legislation in different countries and specific legislation on ingredients. The central body of the book addresses analytical methods for monitoring and quality control of cosmetic products with the fundamental objective being to enable reader's access to scientific reviews carried out by experts in analytical chemistry. The final section contains a small review of the alternative methods to using animals for cosmetic product evaluation. * An essential resource for those in the cosmetic industry and research laboratories, allowing you to become familiar with the main analytical literature * Up-to-date and exhaustive overviews of current knowledge dealing with cosmetic analysis, general concepts and legislation * Including tables and figures, designed to graphically communicate important information in an easy-to-understand format

This edited volume discusses the theoretical, ethical and practical considerations involved in the assessment of Second Language Learners (SLLs) with Specific Language Learning Disorders (SpLD), such as dyslexia and Attention Deficit and Hyperactivity Disorder, and with other disabilities like visual and hearing impairments. The volume contains 14 chapters. These explore various theoretical models and research findings that identify and evaluate the language and special needs of SLLs with SpLD and other disabilities and evaluate the effectiveness of the accommodation practices employed so far. The studies involve both high-stakes tests and classroom-based assessments conducted by professionals and researchers working in the areas of psychology, special education and second/foreign language testing and assessment from various countries around the globe, including the USA, Canada, New Zealand and European countries such as Italy, UK, Greece, Germany, and Slovenia. The volume accommodates high-quality submissions that cover a gap in a research area that has long been in need of theoretical and empirical attention. This volume will become a valuable point of reference and springboard for future research initiatives.

"Several interdisciplinary studies highlight imperfect information as a possible explanation of skill mismatches, which in turn has implications for unemployment and informality rates. Despite information failures and their consequences, countries like Colombia (where informality and unemployment rates are high) lack a proper labour market information system to identify skill mismatches and employer skill requirements. One reason for this absence is the cost of collecting labour market data. Recently, the potential use of online job portals as a source of labour market information has gained the attention of researchers and policymakers, since these portals can provide quick and relatively low-cost data collection. As such, these portals could be of use for Colombia. However, debates continue about the efficacy of this use, particularly concerning the robustness of the collected data. This book implements a novel mixed-methods approach (such as web scraping, text mining, machine learning, etc.) to investigate to what extent a web-based model of skill mismatches can be developed for Colombia. The main contribution of this book is demonstrating that, with the proper techniques, job portals can be a robust source of labour market information. In doing so, it also contributes to current knowledge by developing a conceptual and methodological approach to identify skills, occupations, and skill mismatches using online job advertisements, which would otherwise be too complex to be collected and analysed via other means. By applying this novel methodology, this study provides new empirical data on the extent and nature of skill mismatches in Colombia for a considerable set of non-agricultural occupations in the urban and formal economy. Moreover, this information can be used as a complement to household surveys to monitor potential skill shortages. Thus, the findings are useful for policymakers, statisticians, and education and training providers, among others."
