The understanding and retention of Mathematics lessons is a challenge faced by teachers, parents and the Department of Basic Education. This could be caused by the fact that most learners learn Mathematics in English, which is not their home language. This results in them taking time to translate into isiXhosa each concept taught by the teacher. This dictionary comes as a response to that problem, for learners and teachers. The way it is written makes it easy for even parents to navigate through it when explaining difficult Mathematical concepts to their children when assisting them in their studies. Explaining the English Mathematical concepts is difficult for parents, more especially those who never studied Mathematics. This dictionary is good because each concept is defined in both English and isiXhosa. The terms selected here were chosen by Mathematics experts and teachers. These are the people who work with learners, and who also understand their Mathematical challenges. The Mathematics Dictionary is a Mathematics support material that can be used by the learner, teacher and the parent at home. Each defined term is supported by a picture that is based on the life and society of the isiXhosa speaking people. This is one of the aspects that will make the learners enjoy using this dictionary, because it talks about things that they know and are accustomed to, even though they do not take them as Mathematical concepts.

What happens when enemies work to advance similar goals? Who wins, who loses, and why? In Frenemies, Nancy Whittier addresses this question through a study of feminist and conservative opposition to pornography, campaigns against child sexual abuse, and engagement on the Violence Against Women Act. Drawing on extensive research, Whittier shows how feminist and conservative activists interacted with each other and with the federal government, how their interaction affected them, and what each side achieved. Whittier re-conceptualizes relationships between social movements, presenting a model of how "frenemies"-groups that are neither allies nor opponents-work toward related goals. She outlines the dynamics and paths of frenemy relationships, describing the unintended consequences for the groups involved and for their respective movements at large. With high levels of political polarization across the U.S., Frenemies provides a crucial look at both the promise and the risk of cooperation across political differences.

An informal and highly accessible writing style, a simple treatment of mathematics, and clear guide to applications have made this book a classic text in electrical and electronic engineering. The fundamental ideas relevant to the understanding of the electrical properties of materials are emphasized; in addition, topics are selected in order to explain the operation of devices having applications (or possible future applications) in engineering. The mathematics, kept deliberately to a minimum, is well within the grasp of undergraduate students. This is achieved by choosing the simplest model that can display the essential properties of a phenomenom, and then examining the difference between the ideal and the actual behaviour. The whole text is designed as an undergraduate course. However most individual sections are self contained and can be used as background reading in graduate courses, and for interested persons who want to explore advances in microelectronics, lasers, nanotechnology, and several other topics that impinge on modern life.

Musical Minorities is the first English-language monograph on the performing arts of an ethnic minority in Vietnam. Living primarily in the northern mountains, the Hmong have strategically maintained their cultural distance from foreign invaders and encroaching state agencies for almost two centuries. They use cultural heritage as a means of maintaining a resilient community identity, one which is malleable to their everyday needs and to negotiations among themselves and with others in the vicinity. Case studies of revolutionary songs, countercultural rock, traditional vocal and instrumental styles, tourist shows, animist and Christian rituals, and light pop from the diaspora illustrate the diversity of their creative outputs. This groundbreaking study reveals how performing arts shape understandings of ethnicity and nationality in contemporary Vietnam. Based on three years of fieldwork, Lonan O Briain traces the circulation of organized sounds that contribute to the adaptive capacities of this diverse social group. In an original investigation of the sonic materialization of social identity, the book outlines the full multiplicity of Hmong music-making through a fascinating account of music, minorities, and the state in a post-socialist context.

White supremacy is on the rise in the world once again, often finding expression in acts of extreme violence by young white men.

Gavin Evans explores the roots of this ideology, traced back to the 19th century to Charles Darwin and Francis Galton’s race-based theories. He examines the spread of eugenics and the rise of Nazism and Apartheid.

Evans further investigates the 21st-century evolution of ‘Great Replacement’ ideas, their spread through alt-right forums, and their influence on young men with access to weapons. White Supremacy reveals the connections between mainstream and extremist ‘Replacement Theory’ and the ongoing promotion of race science by both far-right and establishment figures, highlighting the dangerous legacy of eugenics.
