As a continuation of the earlier volumes in this series, the proceedings of the Eighth International Conference provide authoritative and up-to-date information on pig reproduction research. This volume, which contains manuscripts accompanying the state-of-the art lectures, the parallel sessions, and the expanded abstracts, provides an authoritative and up-to-date source of information on research in pig reproduction. This text is an invaluable resource for students, teachers, veterinarians, animal scientists, consultants, and technologists with an interest in all aspects of pig reproduction.

Emphasizing the role that vivid personalities – including engineers John Laing Weller and Alex Grant as well as contractors and labourers – played in the construction of the canal, Roberta Styran and Robert Taylor use archival sources, government documents, newspapers, maps, and original plans to describe a saga of technological, financial, geographical, and social obstacles met and overcome in an accomplishment akin to the building of the Canadian Pacific Railway. A story of Canadian skill, courage, vision, and hardship, This Colossal Project details the twenty-year excavation of the giant channel and the creation of huge concrete locks amidst war, the Great Depression, political change, and labour unrest.

This book presents the texts of selected lectures on recent work in the field of nonlinear partial differential equations delivered by leading international experts at the well-established weekly seminar held at the Collège de France. Emphasis is on applications to numerous areas, including control theory, theoretical physics, fluid and continuum mechanics, free boundary problems, dynamical systems, scientific computing, numerical analysis, and engineering. Proceedings of this seminar will be of particular interest to postgraduate students and specialists in the area of nonlinear partial differential equations.

In Beyond Constraint, Shona N. Jackson offers a new approach to labour and its analysis by demonstrating the fundamental relation between black and Indigenous People’s sovereign, free, and coerced labour in the Americas. Through the writings of Cedric Robinson, Walter Rodney, C. L. R. James, and Sylvia Wynter, Jackson confronts the elision of Indigenous People’s labour in the black radical tradition. She argues that this elision is an effect of the structural relation of antiblackness to anti-indigeneity through which native and black bodies are arranged on either side of a split between unproductive labour and productive work necessary for capital accumulation and for how we read capital in political economic critique. This division between labour and work forces the radical tradition to sustain the break between black and Indigenous peoples as part of its critical strategies of liberation. To address this impasse, Jackson reads the tradition against the grain for openings to indigeneity and a method for recovering lost labours.

Metropolitan areas with a high concentration of headquarters from diverse industries stand out as influential, dynamic economies. However, there is little discussion about the characteristics of these 'headquarters economies'. Why do some regions develop vibrant headquarters economies, whereas others do not? The answer lies in understanding the essence of headquarters - the managerial talent pool that guides and governs these companies. By investigating an exemplar headquarters economy - Minneapolis-St. Paul - this volume demonstrates that the talent pool (managers), its movement among companies and industries in a region (mobility), and the nature of its inflow and outflow from a region (migration), can create a virtuous cycle that strengthens regional companies, and draws in additional talent. Comparing the migration pattern of educated, high-earning individuals across metropolitan areas in the United States, and drawing upon a proprietary survey of thousands of headquarters employees in Minneapolis-St. Paul, this book provides supportive evidence for this dynamic. A central insight of the research is that professional managerial talent is a determinant of regional vitality that has largely been overlooked. The underlying factors of managers, mobility, and migration, here identified in the context of Minneapolis-St. Paul, exist in metropolitan areas around the world, demonstrating the scope of application of the research findings, and highlighting the benefit of focusing on these underlying factors.
