Prisms Of Work

The phenomenon of labour takes the character of a prism. Labour is thereby always context dependent and constituted through the actions of all protagonists involved in any labour relationship. On the basis of three case studies in colonial German East Africa - the construction of the Central Railway (1905-1916), the Otto Plantation in Kilossa (1907-1916) and the palaeontological Tendaguru Expedition (1909-1911) - labour and labour relations are analysed. The focus lies on hitherto neglected actors and groups of actors of labour in the colonial context of East Africa. These were especially German companies and their staff, white subaltern railway sub-contractors and labour recruiters, Indian skilled workers and (qualified) East African workers. Furthermore, all three sites of labour proved to have their individual logics and characteristics. But all of them were in tension between the 'global' and the 'local', coercion and voluntariness, machine and manual labour, skilled and unskilled labour, reproductive and wage labour, as well as between black and white.

Prism and Lens Making: A Textbook for Optical Glassworkers, Second Edition is a unique compendium of the art and science of the optical working of glass for the production of mirrors, lenses, and prisms. Incorporating minor corrections and a foreword by Professor Walter Welford FRS, this reissue of the 1957 edition provides a wealth of technical information and hands-on guidance gained from a lifetime of experience. Although some of the techniques have been replaced by more modern methods, this classic book is still a valuable source of practical assistance as well as being a pleasure to read.

This book examines women’s activism in and beyond Central and Eastern Europe and transnationally within and across different historical periods, political regimes, and scales of activism. The authors explore the wide range of activist agendas, repertoires, and forums in which women sought to advocate for their gender and labour interests. Women were engaged in trade unions, women-only organizations, state institutions, and international and intellectual networks, and were active on the shopfloor. Rectifying geopolitical and thematic imbalances in labour and gender history, this volume is a valuable resource for scholars and students of women’s activism, social movements, political and intellectual history, and transnationalism.

Grassroots organizing and collective action have always been fundamental to American democracy but have been burgeoning since the 2016 election, as people struggle to make their voices heard in this moment of societal upheaval. Unfortunately much of that action has not had the kind of impact participants might want, especially among movements representing the poor and marginalized who often have the most at stake when it comes to rights and equality. Yet, some instances of collective action have succeeded. What’s the difference between a movement that wins victories for its constituents, and one that fails? What are the factors that make collective action powerful? Prisms of the People addresses those questions and more. Using data from six movement organizations—including a coalition that organized a 104-day protest in Phoenix in 2010 and another that helped restore voting rights to the formerly incarcerated in Virginia—Hahrie Han, Elizabeth McKenna, and Michelle Oyakawa show that the power of successful movements most often is rooted in their ability to act as “prisms of the people,” turning participation into political power just as prisms transform white light into rainbows. Understanding the organizational design choices that shape the people, their leaders, and their strategies can help us understand how grassroots groups achieve their goals. Linking strong scholarship to a deep understanding of the needs and outlook of activists, Prisms of the People is the perfect book for our moment—for understanding what’s happening and propelling it forward.

Some of the artworks pose difficulties in interpretation, but regardless of amorphous subjects and confusing representations, Butor's creativity finds poetry in them.".

In this original work, Chesbro presents a different kind of mystery as he plumbs the depths of a badly bruised writer's heart and soul.

About the Author Frank Twyman was a skilled craftsman in all aspects of optics. He joined Otto Hilger in 1898 to work on the production of simple spectroscopes costing less than £10 each. After the death of Otto Hilger, Twyman became Managing Director of Adam Hilger Ltd., a company known for the finest quality optical and mechanical work. He worked here from 1902 to 1946 and was very concerned with the practical aspects of instrument making; he designed many of the instruments himself and constantly strove to improve the techniques of optical grinding and polishing. In 1916 Twyman and Alfred Green, the foreman of the Hilger optical shops, patented the now-famous prism and lens testing interferometer that bears their names. Twyman also undertook fundamental studies in the annealing process for glass and invented new spectrophotometers and spectrographs.
