Book Description
Input and Evidence: the raw material of second language acquisition is an empirical and theoretical treatment of one of the essential components of SLA: the input to language learning mechanisms. It reviews and adds to the empirical studies showing that negative evidence (correction, feedback, repetitions, reformulations) play a role in language acquisition in addition to that played by ordinary conversation. At the same time, it embeds discussion of input within a framework which includes a serious treatment of language processing, including the problem of modularity and the question of how semantic representations can influence grammatical ones. It lays the foundation for the development of a truly explanatory theory of SLA in the form of the Autonomous Induction Theory which combines a model of induction with an interpretation of Universal Grammar, thereby permitting, for the the first time, a coherent approach to the problem of constraining induction in SLA.

Book Description
Emphasizing the necessity for theory-driven language acquisition research, the studies in this collection aim to formalize the kinds of information available to first and second language learners, as well as to shed light on how that information is used to solve a variety of learning problems. The volume pays homage to the scholarly contributions of Susanne E. Carroll, delving into the impact she has had on the field of language acquisition. The central themes of input, evidence, and exposure – found throughout Carroll’s work – are explored in this volume. The contributions cover a range of topics such as the emergence of linguistic theorizing in language acquisition research, the acquisition of grammatical gender, classroom language learning, learning on first exposure, asymmetries between developmental trajectories in first and second language acquisition, and the effects of grammatical complexity on language development.

Book Description
Language addressed to children, or 'Baby Talk', became the subject of research interest thirty years ago. Since then, the linguistic environment of infants and toddlers has been widely studied. Input and Interaction in Language Acquisition is an up-to-date statement of the facts and controversies surrounding 'Baby Talk', its nature and likely effects. With contributions from leading linguists and psychologists, it explores language acquisition in different cultures and family contexts, in typical and atypical learners, and in second and foreign language learners. It is designed as a sequel to the now famous Talking to Children, edited by Catherine Snow and Charles Ferguson, and Professor Snow here provides an introduction, comparing issues of importance in the field today with the previous concerns of researchers.

Book Description
The Handbook of Second Language Acquisition presents an integrated discussion of key, and sometimes controversial, issues in second language acquisition research. Discusses the biological and cognitive underpinnings of SLA, mechanisms, processes, and constraints on SLA, the level of ultimate attainment, research methods, and the status of SLA as a cognitive science. Includes contributions from twenty-seven of the world's leading scholars. Provides an invaluable resource for all students and scholars of human cognition, including those in linguistics, psychology, applied linguistics, ESL, foreign languages, and cognitive science.

Book Description
In the last two decades, manufacturing industries in Korea have become more concentrated, and interconnectedness across industries and to foreign countries has risen via vertical relationships and trade linkages. This paper investigates the transmission of economic shocks in such a highly concentrated and interconnected structure, focusing on the role of vertical and trade linkages and using the industry-level international input-output data. The results suggest that, first, the role of vertical and trade linkages in propagating growth shocks from both domestic sources and external sources is important. Second, the growth impact of a few key sources of economic shocks is relatively large. These findings highlight that economic shocks in a few key industries and/or major trading partners that are transmitted through vertical and trade linkages can lead to large swings in the overall economy. This paper contributes to the understanding of the potential interactions between the industrial structure and economic growth and stability.

Book Description
Increasing population pressure and population density in many African countries are inducing land scarcity and land constraints. These increasing land constraints are expected to trigger various responses and adaptation strategies, including agricultural intensification induced by land scarcity, as postulated by the Boserup hypothesis. However, most empirical evaluations of the Boserup hypothesis come from rainfed agriculture and mostly from Sub-Saharan Africa (SSA), where application of improved agricultural inputs remains historically low. Agricultural intensification practices as well as the relevance of the Boserup hypothesis in irrigated agriculture and in contexts where application of improved inputs is high remains unexplored. Furthermore, while much of the debate on the topic in Africa has focused on how to boost agricultural intensification, there is scant evidence on whether evolving agricultural intensification practices in some parts of Africa are sustainable, yield-enhancing, and optimal. In this paper we investigate the implication of land scarcity on agricultural intensification and the relevance of the Boserup hypothesis in the context of Egypt, where agriculture is dominated by irrigation and input application rates are much higher than SSA. We also examine whether evolving agricultural intensification practices induced by land scarcity are agronomically appropriate and yield-enhancing. We find that land scarcity induces higher application of agricultural inputs, mainly nitrogen fertilizers, sometimes beyond the level that is agronomically recommended. More importantly, land scarcity increases overapplication of nitrogen fertilizer relative to crop-specific agronomic recommendations. This implies that land constraints remain as important challenges for sustainable agricultural intensification. Finally, we find suggestive evidence that such overapplication of nitrogen fertilizers is not yield-enhancing, but, rather, yield-reducing. We also document that land scarcity impedes mechanization of agriculture. Our findings have important implications to inform appropriate farm management and sustainable intensification practices. Furthermore, our results can inform long-term policy responses to land scarcity.

Book Description
This volume bridges the gap between theory and practice by bringing together well-known and new authors to discuss a topic of mutual interest to second language researchers and teachers alike: input. Reader-friendly chapters offer a range of existing and new perspectives on input in morphology, syntax, phonetics and phonology.
