Nelson Mandela: A Very Short Introduction (Paperback, 2nd Revised edition): Elleke Boehmer Nelson Mandela: A Very Short Introduction (Paperback, 2nd Revised edition)
Elleke Boehmer
R280 R228 Discovery Miles 2 280 Save R52 (19%) Ships in 9 - 15 working days

Very Short Introductions: Brilliant, Sharp, Inspiring A pathbreaking analysis of the relationship between Mandela the myth, and Mandela the historical figure, looking at the way images, stories, and politics have been combined to create the iconic image of Mandela that we know today. Boehmer explores the long trajectory of Mandela's life, explaining first the historical and political context of the struggle against apartheid in South Africa, and then the post-apartheid period of difficult reconciliation, including the shifts and changes in Mandela's reputation since the millennium. This innovative postcolonial reflection takes on board the more critical revisionist literature on Mandela that has emerged since 2015, looking at responses to his death in 2014, and the 2018 commemorations of the 100th anniversary of his birth. The first edition set a trend in scholarship on Mandela by reading his character and achievements through the lens of his influences, interests, and leading ideas. The second edition extends this focus with a far-reaching critical look at meanings of reconciliation and Mandela's ethic of reciprocity. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

International Environmental Policy - Interests and the Failure of the Kyoto Process (Hardcover): Sonja Boehmer-Christiansen,... International Environmental Policy - Interests and the Failure of the Kyoto Process (Hardcover)
Sonja Boehmer-Christiansen, Aynsley Kellow
R3,061 Discovery Miles 30 610 Ships in 12 - 17 working days

The Kyoto Protocol has singularly failed to shape international environmental policy-making in the way that the earlier Montreal protocol did. Whereas Montreal placed reliance on the force of science and moralistic injunctions to save the planet, and successfully determined the international response to climate change, Kyoto has proved significantly more problematic. International Environmental Policy considers why this is the case. The authors contend that such arguments on this occasion proved inadequate to the task, not just because the core issues of the Kyoto process were subject to more powerful and conflicting interests than previously, and the science too uncertain, but because the science and moral arguments themselves remained too weak. They argue that 'global warming' is a failing policy construct because it has served to benefit limited but undeclared interests that were sustained by green beliefs rather than robust scientific knowledge. This highly topical book takes a frank look at the political motivations that underpin the global warming debate, and will appeal to political scientists and energy policy analysts as well as anyone with an interest in the future of the environment and in the policies we create to protect it.

The International Politics of Climate Change (Hardcover): Aynsley Kellow, Sonja Boehmer-Christiansen The International Politics of Climate Change (Hardcover)
Aynsley Kellow, Sonja Boehmer-Christiansen
R8,629 Discovery Miles 86 290 Ships in 12 - 17 working days

This highly topical collection, edited by two accomplished academics, explores how environmental science and energy policy relate to international politics and policy. This complex and essentially interdisciplinary subject has been the core about which academics have fiercely debated and, as yet, unsuccessfully reached satisfactory negotiations. The editors interpret the politics of climate change as being driven less by scientific understanding than by disguised interests and deeply believed norms. The carefully selected papers in this volume both analyse and advocate policies that claim to be directed towards ?combating man-made global warming? and hence ?save the planet?.

Dentistry in Rabbits and Rodents (Hardcover): E Boehmer Dentistry in Rabbits and Rodents (Hardcover)
E Boehmer
R2,512 Discovery Miles 25 120 Ships in 12 - 17 working days

Dentistry in Rabbits and Rodents is a practical guide aimed at helping clinicians successfully diagnose and treat dental problems in rabbits and rodents within their own surgeries. With over two-thirds of small mammals presenting with tooth related problems, there is great potential to enhance the treatment offered to the owners of these species. Focusing on innovative diagnostics using normal radiographic machines as well as specific positioning techniques, radiographs are presented with reference lines and detailed annotations. Richly illustrated with high quality photographs, pathological findings are described before selection of appropriate therapy and treatment is discussed. Key features include: * Covers the dental anatomy and physiology of all small mammal species commonly kept as pets. * Intraoral radiography and innovative positioning for imaging the guinea pig and chinchilla dentitions are described, enabling the practitioner to visualize each tooth in detail. * Once a diagnosis has been reached, selection of different treatments and the advantages and disadvantages of each surgical technique are discussed. * Offers helpful directives for approaching and treating dental disease without the need for referral to a specialist or the use of expensive equipment.

Planned Violence - Post/Colonial Urban Infrastructure, Literature and Culture (Hardcover, 1st ed. 2018): Elleke Boehmer,... Planned Violence - Post/Colonial Urban Infrastructure, Literature and Culture (Hardcover, 1st ed. 2018)
Elleke Boehmer, Dominic Davies
R3,697 Discovery Miles 36 970 Ships in 12 - 17 working days

This book brings the insights of social geographers and cultural historians into a critical dialogue with literary narratives of urban culture and theories of literary cultural production. In so doing, it explores new ways of conceptualizing the relationship between urban planning, its often violent effects, and literature. Comparing the spatial pasts and presents of the post-imperial and post/colonial cities of London, Delhi and Johannesburg, but also including case studies of other cities, such as Chicago, Belfast, Jerusalem and Mumbai, Planned Violence investigates how that iconic site of modernity, the colonial city, was imagined by its planners - and how this urban imagination, and the cultural and social interventions that arose in response to it, made violence a part of the everyday social life of its subjects. Throughout, however, the collection also explores the extent to which literary and cultural productions might actively resist infrastructures of planned violence, and imagine alternative ways of inhabiting post/colonial city spaces.

R2,731 Discovery Miles 27 310 Ships in 12 - 17 working days

India has often been at the centre of debates on and definitions of the postcolonial condition. Offering a challenging new direction for the field, this Critical Reader confronts how theory in the Indian context is responding in vital terms to our understanding of that condition today.

The Indian Postcolonial: A Critical Reader is made up of four sections looking in turn at:

  • visual cultures
  • translating cultural traditions
  • the ethical text
  • global/cosmopolitan worlds.

Each section is prefaced with a short introduction by the editors that locate these interdisciplinary articles within the contemporary national and international context. Showcasing the diversity and vitality of current debate, this volume collects the work of both established figures and a new generation of cultural critics.

Challenging and unsettling many basic premises of postcolonial studies, this volume is the ideal Reader for students and scholars of the Indian Postcolonial.

The historic encounter around 1911 between the composer Arnold Schonberg and the painter Wassily Kandinsky occurred at a moment when the first wild revolts against traditional art - Dada and Futurism - had just manifested themselves. This volume is a collection of the papers presented at the conference on Schonberg and Kandinsky at the Royal Conservatory in The Hague in January 1993. The conference focused on the varying aspects of the avant-garde from 1910 to 1913, when both Schonberg and Kandinsky formulated their far-reaching views on the ways in which music and painting should develop, and discussed their common interest in new theatrical forms of presentation.

Schonberg and Kandinsky - An Historic Encounter (Paperback): Konrad Boehmer Schonberg and Kandinsky - An Historic Encounter (Paperback)

The historic encounter around 1911 between the composer Arnold Schonberg and the painter Wassily Kandinsky occurred at a moment when the first wild revolts against traditional art, Dada and Futurism, had just manifested themselves. Independently of those sometimes spectacular activities, both Schonberg and Kandinsky had already concluded that the material and the compositional methods they had relied on in the past were exhausted and did not satisfy the development of their artistic ideas.
Both artists had already submitted their modes of production to a critical analysis which resulted in Schonberg's Theory of Harmony and Kandinsky's Concerning the Spiritual in Art, both of 1911 - indeed the two artists had already been putting their self-criticism into practice for some time. In Schonberg's case this led to breaking with tonality; Kandinsky effected the transition to abstract painting.
This book is a collection of the papers presented at the conference on Schonberg and Kandin

This book summarizes what is currently known about gravity sensing and response mechanisms in microorganisms, fungi, lower and higher plants; starting from the historical eye-opening experiments from the 19th century up to today's extremely rapid advancing cellular, molecular and biotechnological research. All forms of life are constantly exposed to gravity and it can be assumed that almost all organisms have developed sensors and respond in one way or the other to the unidirectional acceleration force,this books shows us some of these different ways. The book is written for plant biologists and microbiologists as well as scientists interested in space and gravitational biology.

This book covers the scope of current knowledge of cancer in the LGBT community across the entire cancer continuum, from understanding risk and prevention strategies in LGBT groups, across issues of diagnosis and treatment of LGBT patients, to unique aspects of survivorship and death and dying in these communities. Each chapter includes an in depth analysis of the state of the science, discusses the many remaining challenges and unanswered questions and makes recommendations for research, policy and programmatic strategies required to address these. Focus is also placed on the diversity of the LGBT communities. Issues that are unique to cancer in LGBT populations are addressed including the social, economic and cultural factors that affect cancer risk behaviors, barriers to screening, utilization of health care services, and legislation that directly impacts the health care of LGBT patients, healthcare settings that are heterosexist and unique aspects of patient-provider relationships such as disclosure of sexual orientation and the need for inclusion of expanded definition of family to include families of choice. The implications of policy change, its impact on healthcare for LGBT patients are highlighted, as are the remaining challenges that need to be addressed. A roadmap for LGBT cancer prevention, detection, diagnosis, survivorship, including treatment and end of life care is offered for future researchers, policy makers, advocates and health care providers.

R1,585 Discovery Miles 15 850 Ships in 10 - 15 working days

Symmetry is a property which occurs throughout nature and it is therefore natural that symmetry should be considered when attempting to model nature. In many cases, these models are also nonlinear and it is the study of nonlinear symmetric models that has been the basis of much recent work. Although systematic studies of nonlinear problems may be traced back at least to the pioneering contributions of Poincare, this remains an area with challenging problems for mathematicians and scientists. Phenomena whose models exhibit both symmetry and nonlinearity lead to problems which are challenging and rich in complexity, beauty and utility. In recent years, the tools provided by group theory and representation theory have proven to be highly effective in treating nonlinear problems involving symmetry. By these means, highly complex situations may be decomposed into a number of simpler ones which are already understood or are at least easier to handle. In the realm of numerical approximations, the systematic exploitation of symmetry via group repre sentation theory is even more recent. In the hope of stimulating interaction and acquaintance with results and problems in the various fields of applications, bifurcation theory and numerical analysis, we organized the conference and workshop Bifurcation and Symmetry: Cross Influences between Mathematics and Applications during June 2-7,8-14, 1991 at the Philipps University of Marburg, Germany."

For more than ten years cell fusion techniques have been applied in studies on various lymphocyte functions. Ig expression was first studied in hybrids obtained by fusing myeloma cells with fibroblasts (1) or lymphomas (2), both of which do not produce Ig, and with Ig producing myelomas (3) or human blood lymphocytes (4). Kohler and Milstein (5) fused a myeloma with spleen cells from immunized mice. Up to 10% of the hybrids obtained secreted antibodies specific for the immunizing antigen. This suggested that plasma cells preferenti ally fused with the myeloma cells, a finding which was of enormous practical value. It was found that both Band T lymphocytes could be fused with the T cell tumor BW5147, which is however not permissive for Ig synthesis (6). A very large number of T cell hybridomas were generated by fusing BW5147 with cell populations containing in vivo or in vitro activated cells (7). The hybrids showed no specific T cell functions and binding assays for T cell receptors were not available. In particular, no hybrids were obtained which expreS1ed specific cytolytic activity that could be tested in short-term Cr release assays (8). However, the frustrations expressed about these failures, published in January, 1978 (9), were relieved by Taniguchi and Miller's publication a few months later of T cell hybridomas producing antigen-specific suppressor factors (10). Unfortunately, their hybrids rapidly lost factor production."

The tenn "calixarenes," introduced in 1978 by D. Gutsche to describe the cyclic oligomers produced by condensation of p-substituted phenols with fonnaldehyde, is now universally accepted in the chemical community. The condensation of phenol with fonnaldehyde was studied in the last century by A. von Baeyer. Early in this century, L. Baekeland produced the first entirely synthetic polymers from phenol-fonnaldehyde condensates and the possibility that cyclic condensation products could be obtained from t-butylphenol, and fonnaldehyde was mentioned as early as in the beginning of the 1940's by A. Zinke. Despite their long history, the realisation that calixarenes may have very significant applications and uses in supramolecular chemistry is a relatively recent phenomenon. Calixarene chemistry, in contrast to their discovery, started slowly in the 1970's but rapidly gained momentum throughout the 1980's. Following C. Pedersens discovery of the crown ethers and the seminal developments of J. -M. Lehn and D. Cram with cryptands and spherands - all three honoured with the 1987 Nobel Chemistry Prize - the time was right for a surge of interest in research areas, frequently referred to as host-guest chemistry, receptor or supramolecular chemistry, and including important comparisons with biological processes and the development of new advanced materials. Now, the cyclic, bowl or basket-shaped calixarene molecules were looked on in a different light. Rather than "having developed from harmful by-products of phenoplasts manufacture" they were now seen as potentially valuable macrocyclic receptor molecules.

The Technology Program GAST was executed from 1981 to 1987 as a German-Spanish joint program aiming at the development and the investigation of necessary solar specific components and software for a gas-cooled tower power station of medium size. After the tests had been successfully completed at the Plata forma Solar de Almeria in 1987, the proceedings are now presented to inform the experts and the public about these developments and their results. Not intending to anticipate a detailed valuation of the results, however, we as the project monitors of the Technology program resume that the intended aims are nearly entirely achieved and that principally the way for the construction and operation of a gas cooled solar tower power plant has been prepared. Essential for this successful completion were not only a promising concept, a careful design, a precise plan ning, solid fabrication and installation as well as careful tests, but also the extraordinarily good cooperation between the engaged companies, institutes, organisations and advisory groups."
