Shape Understanding System - Knowledge Implementation and Learning

Human color perception is widely understood to be based on a neural coding system involving signals from three distinct classes of retinal photoreceptors. This retina processing model has long served as the mainstream scientific template for human color vision research and has also proven to be useful for the practical design of display technologies, user interfaces, and medical diagnosis tools that enlist human color perception behaviors. Recent findings in the area of retinal photopigment gene sequencing have provided important updates to our understanding of the molecular basis and genetic inheritance of individual variations of human color vision. This Element focuses on new knowledge about the linkages between color vision genetics and color perception variation and the color perception consequences of inheriting alternative, nonnormative, forms of genetic sequence variation.

This book explores one of the most intractable problems of human existence - our propensity to inflict violence. It provides readers with case studies of political, social, economic, religious, structural and interpersonal violence from across the entire globe since 1800. It also examines the changing representations of violence in diverse media and the cultural significance of its commemoration. Together, the chapters provide in-depth understanding of the ways that humans have perpetrated violence, justified its use, attempted to contain its spread and narrated the stories of its impacts. Readers also gain insight into the mechanisms by which the parameters about the acceptable limits to and locations of violence have dramatically altered over the course of a few decades. Leading experts from around the world have pooled their knowledge to provide concise, authoritative examinations of the complex phenomenon of human violence. Annotated bibliographies provide overviews of the shape of

An ancient metaphor likens attention to an archer pulling her bow - the self directing her mind through attention. Yet both the existence of such a self, and the impact of attention on the mind, have been debated for millennia. Advancements in science mean that we now have a better understanding of what attention is and how it works, but philosophers and scientists remain divided as to its impact on the mind. This book takes a strong stance: attention is the key to the self, consciousness, perception, action, and knowledge. While it claims that we cannot perceive novel stimuli without attention, it argues that we can act on and experience the world without attention. It thus provides a new way of thinking about the mind - as something that can either shape itself through attention or engage with the world as it is given, relying on its habits and skills.

Dynamics of Caste and Law breaks new ground in understanding how caste and law relate in India's democratic order. Caste has become a visible phenomenon often associated with discrimination, inequality and politics in India and globally. India's constitutional democracy has had a remarkable goal of creating equality in a context of caste. Despite constitutional promises with equal opportunities for the lower castes and outlawing of untouchability at the time of independence, recurring atrocities and inadequate implementation of law have called for rethinking and legal change. This book sheds new light on why caste oppression persists by using new theoretical perspectives as well as Bhimrao Ambedkar's concepts of the caste system. Focusing on struggles among India's Dalits, the castes formerly known as untouchables, the book draws on a rich material and explains, among other things, mechanisms of oppression and how powerful actors may gain influence in institutions of law and state.

This is the first comparative and comprehensive account of occupational training before the Industrial Revolution. Apprenticeship was a critical part of human capital formation, and, because of this, it has a central role to play in understanding economic growth in the past. At the same time, it was a key stage in the lives of many people, whose access to skills and experience of learning were shaped by the guilds that trained them. The local and national studies contained in this volume bring together the latest research into how skills training worked across Europe in an era before the emergence of national school systems. These essays, written to a common agenda and drawing on major new datasets, systematically outline the features of what amounted to a European-wide system of skills education, and provide essential insights into a key institution of economic and social history.

Written by educational researchers and professionals working with children and adolescents in and out of school, this book shows how self-regulation involves more than an isolated individual's ability to control their thoughts and feelings, particularly in a learning environment. By using Vygotsky's cultural-historical psychological theory, the authors provide a unique set of four analytical lenses for a better understanding of how self-regulation, co-regulation, and other-regulation function as a system of regulatory processes. These lenses move beyond a focus on solitary individuals, who self-regulate behavior, to centre on individuals as relational, agential, and contextually situated. As agents, teachers and their students build their learning contexts and are influenced by these self-engineered contexts. This is a dynamic perspective of a social context and underlies the view that regulatory processes are an integral part of a functional system for learning.

Learning by Expanding challenges traditional theories that consider learning to be a process of acquisition and reorganization of cognitive structures within the closed boundaries of specific tasks or problems. Yrjö Engeström argues that this type of learning increasingly fails to meet the challenges of complex social change and fails to create novel artifacts and ways of life. In response, he presents an innovative theory of expansive learning activity, offering a foundation for understanding and designing learning as a transformation of human activities and organizations. The second edition of this seminal text features a substantive new introduction that illustrates the development and implementation of Engeström's theory since its inception.

Speech is the most effective medium humans use to exchange and transmit knowledge, ideas and experiences. It exists physiologically as neural and muscular activity, and subsequent articulatory, acoustic and auditory events, and as an abstract, rule-governed system at the psychological level. Together, both levels produce communication by speech. To appreciate speech and its communicative function, all of its characteristics must be understood. This book offers the most comprehensive and accessible coverage of the three areas of phonetics: articulatory, acoustic, and auditory or speech perception. Students without a linguistics background can be daunted by phonetics, so clear language is used to define linguistics and phonetics concepts with examples and illustrations to ensure understanding. Furthermore, each chapter concludes with comprehension exercises to reinforce understanding. Online exercises and recordings of speech stimuli from various languages provide additional opportunity

Research on learning and cognition in geoscience education research and other discipline-based education communities suggests that effective instruction should include three key components: a) activation of students' prior knowledge on the subject, b) an active learning pedagogy that allows students to address any existing misconceptions and then build a new understanding of the concept, and c) metacognitive reflections that require students to evaluate their own learning processes during the lesson. This Element provides an overview of the research on student-centered pedagogy in introductory geoscience and paleontology courses and gives examples of these instructional approaches. Student-centered learning shifts the power and attention in a classroom from the instructor to the students. In a student-centered classroom, students are in control of their learning experience and the instructor functions primarily as a guide. Student-centered classrooms trade traditional lecture for conce

Public–private partnerships (PPPs) play an increasingly prominent role in addressing global development challenges. United Nations agencies and other organizations are relying on PPPs to improve global health, facilitate access to scientific information, and encourage the diffusion of climate change technologies. For this reason, the 2030 Agenda for Sustainable Development highlights their centrality in the implementation of the Sustainable Development Goals (SDGs). At the same time, the intellectual property dimensions and implications of these efforts remain under-examined. Through selective case studies, this illuminating work contributes to a better understanding of the relationships between PPPs and intellectual property considered within a global knowledge governance framework, that includes innovation, capacity-building, technological learning, and diffusion. Linking global governance of knowledge via intellectual property to the SDGs, this is the first book to chart the activit

This book rejects the idea that natural resource industries are doomed to slow growth. Rather, it examines the case of Norway to demonstrate that such industries can prove highly innovative and dynamic.Here, the case is compellingly made that a key empirical problem with the popular ‘resource curse’ argument is that some of the richest countries in the world – namely Norway, Sweden, Canada and Australia – have all developed fast-growing economies based on natural resources. Analysis of innovation and knowledge development in natural resource industries reveal important new insights about the role of learning and innovation. These insights are key to understanding variances in growth levels between natural resource-based economies. Ranestad illustrates how Norway’s high economic performance is built on knowledge-based natural resource industries. While Norwegian industries may have originated because of foreign technology and expertise, they thrived due to further develop

In this major study, Peter Zarrow examines how textbooks published for the Chinese school system played a major role in shaping new social, cultural, and political trends, the ways in which schools conveyed traditional and 'new style' knowledge and how they sought to socialize students in a rapidly changing society in the first decades of the twentieth century. Focusing on language, morality and civics, history, and geography, Zarrow shows that textbooks were quick to reflect the changing views of Chinese elites during this period. Officials and educators wanted children to understand the physical and human worlds, including the evolution of society, the institutions of the economy, and the foundations of the nation-state. Through textbooks, Chinese elites sought ways to link these abstractions to the concrete lives of children, conveying a variety of interpretations of enlightenment, citizenship, and nationalism that would shape a generation as modern citizens of a new China.
