New quantitative methodology and the development of corpus and experimental linguistics tools have recently made researching lexical comprehension and production more accessible. While several tools and data sets are available in English (Coh-metrix, CELEX) and a few other languages, the development of resources and empirical research is still lacking in Spanish. This volume brings together original empirical research and theoretical perspectives that examine lexical development in Spanish L1, L2 and L3, with a focus on different teaching approaches and textbook coverage of Spanish lexicon in L2 curricula and the use of corpus linguistics in methodological investigations. Some questions addressed include the role of lexical development in mapping grammatical acquisition phases, the potential transfers of L1 to L2 lexical abilities, the effect of explicit vocabulary learning techniques in L2, how affective meaning modulates L2 acquisition, or how a typological understanding of lexical organization can help in teaching more effectively the lexicon of a language, among many others. The book offers an overview of what is currently being done in the field of Spanish lexical acquisition through a myriad of approaches and topics.

In a complex and changing world, current scientific approaches to problem solving have drastically evolved to include complexity models and emerging systems. Breaking problems into the smallest component and examining its position inside a system allows for a more regulated and measured technique in investigation, discovery, and providing solutions. Systems Research for Real-World Challenges is an essential reference source that explores the development of systems philosophy, theory, practice, its models, concepts, and methodologies developed as an aid for improving decision making and problem solving for the benefit of organizations and society as a whole. Featuring coverage on a broad range of topics such as complexity models, management systems, and economic policy, this book is ideally designed for scientists, policy makers, researchers, managers, and systematists seeking current research on the benefits and approaches of problem solving within the realm of systems thinking and practice.
