Primary immunodeficiency diseases, first recognized 60 years ago, are inherited disorders that affect human adaptive and innate immunity. In most cases, affected individuals experience recurrent infections, but they may also suffer from autoimmune diseases and malignancies. This third edition of Primary Immunodeficiency Diseases provides readers with the historic and scientific background, clinical presentations, immunologic characteristics, and the molecular/genetic underpinnings of this rapidly enlarging class of diseases. With up-to-date diagnostic tools and therapeutic options - from prophylactic anti-infective measures to hematopoietic stem cell transplantation and gene therapy - this volume will remain an authoritative resource on this increasingly important area.

Victims, Perpetrators, and the Role of Law in Maoist China - A Case-Study Approach (Hardcover): Daniel Leese, Puck Engman Victims, Perpetrators, and the Role of Law in Maoist China - A Case-Study Approach (Hardcover)
Daniel Leese, Puck Engman
R2,503 Discovery Miles 25 030 Ships in 9 - 15 working days

The relationship between politics and law in the early People's Republic of China was highly contentious. Periods of intentionally excessive campaign justice intersected with attempts to carve out professional standards of adjudication and to offer retroactive justice for those deemed to have been unjustly persecuted. How were victims and perpetrators defined and dealt with during different stages of the Maoist era and beyond? How was law practiced, understood, and contested in local contexts? This volume adopts a case study approach to shed light on these complex questions. By way of a close reading of original case files from the grassroots level, the contributors detail procedures and question long-held assumptions, not least about the Cultural Revolution as a period of "lawlessness."

R4,143 Discovery Miles 41 430 Ships in 12 - 17 working days

This research and teaching volume has been composed in honour of Rosalie Tung, a distinguished institution builder, thought leader and educator in the field of international business (IB). The volume addresses Rosalie Tung's main research focus in a career that has already spanned several decades, namely the analysis of distance facing multinational enterprises (MNEs), with a focus on state-of-the-art conceptual and fact-based empirical developments in the realm of cultural and institutional distance elements. The impact of distance on international business transactions and operations remains ill-understood. How should distance be conceptualized? Which dimensions of distance should be considered? Is distance always a cost, or can it sometimes confer value? This twelfth volume in the Progress in International Business Research series presents extensive accounts of the contemporary scientific debate on how to assess the impacts of distance, both negative and positive ones, on the conduct of international business. This volume covers five dimensions related to the concept, cost and value of distance, in International business: * The concept of distance * The cost of cultural and psychic distance * The cost of institutional distance * The value of distance * Alternative lenses for IB research

The brutality and racial hatred exhibited by Japan's military during the Pacific War piqued outrage in the West and fanned resentments throughout Asia. Public understanding of Japan's wartime atrocities, however, often fails to differentiate the racial agendas of its military and government elites from the racial values held by the Japanese people. While not denying brutalities committed by the Japanese military, Honored and Dishonored Guests overturns these standard narratives and demonstrates rather that Japan's racial attitudes during wartime are more accurately discerned in the treatment of Western civilians living in Japan than the experiences of enemy POWs. The book chronicles Western communities in wartime Japan, using this body of experiences to reconsider allegations of Japanese racism and racial hatred. Its bold thesis is borne out by a broad mosaic of stories from dozens of foreign families and individuals who variously endured police harassment, suspicion, relocation, starvation, denaturalization, internment, and torture, as well as extraordinary acts of charity. The book's account of stranded Westerners-from Tokyo, Yokohama, and Kobe to the mountain resorts of Karuizawa and Hakone-yields a unique interpretation of race relations and wartime life in Japan.

This wide-ranging collection seeks to reassess conventional understanding of Japan’s Asia-Pacific War by defamiliarizing and expanding the rhetorical narrative. Its nine chapters, diverse in theme and method, are united in their goal to recover a measured historicity about the conflict by either introducing new areas of knowledge or reinterpreting existing ones. Collectively, they cast doubt on the war as familiar and recognizable, compelling readers to view it with fresh eyes. Following an introduction that problematizes timeworn narratives about a "unified Japan" and its "illegal war" or "race war," early chapters on the destruction of Japan’s diplomatic records and government interest in an egalitarian health care policy before, during, and after the war oblige us to question selective histories and moral judgments about wartime Japan. The discussion then turns to artistic/cultural production and self-determination, specifically to Osaka rakugo performers who used comedy to contend with state oppression and to the role of women in creating care packages for soldiers abroad. Other chapters cast doubt on well-trod stereotypes (Japan’s lack of pragmatism in its diplomatic relations with neutral nations and its irrational and fatalistic military leadership) and examine resistance to the war by a prominent Japanese Christian intellectual. The volume concludes with two nuanced responses to race in wartime Japan, one maintaining the importance of racial categories while recognizing the "performance of Japaneseness," the other observing that communities often reflected official government policies through nationality rather than race. Contrasting findings like these underscore the need to ask new questions and fill old gaps in our understanding of a historical event that, after more than seventy years, remains as provocative and divisive as ever. Defamiliarizing Japan’s Asia-Pacific War will find a ready audience among World War II historians as well as specialists in war and society, social history, and the growing fields of material culture and civic history.

The second edition of Primary Immunodeficiency Diseases presents discussions of gene identification, mutation detection, and clinical and research applications for over 100 genetic immune disorders - disorders featuring an increased susceptibility to infections and, in, certain conditions, an increased rate of malignancies and autoimmune disorders. Since the publication of the first edition, a flurry of new disease entities has been defined and new treatment regimens have been introduced, the most spectacular being successful treatment by gene therapy for two genotypes of combined immunodeficiency. The first edition marked a historic turning point in the field of immunodeficiencies, demonstrating that many of the disorders of the immune system could be understood at a molecular level. This new edition can proudly document the tremendous pace of progress in dissecting the complex immunologic networks responsible for protecting individuals from these disorders.

Marcel Broodthaers filled his twelve-year artistic career with more ideas and works than most artists manage in a lifetime. This career began in 1964, following a period of more than two decades labouring in some obscurity as a poet in the Belgian Surrealist circle of Rene Magritte and Paul Nouge. He also wrote articles on art during these years, including early critiques of Pop art. Traversing media freely - from installation and sculpture to artist's books, prints, film and writings - Broodthaers embodied the `post- media artist' for whom any form could be recruited in the service of a larger conception. Those conceptions included institutional critique (of which he is a pioneer), art-historical critique, pastiche and philosophical-linguistic puzzles. Edited by Broodthaers' daughter Marie-Puck, and with a range of both classic and never-before-seen works, a biography, exhibition chronology and a selected bibliography, this volume is the largest and most authoritative Broodthaers monograph ever published.

Angeregt durch die in Firmendruckschriften und wissenschaftlichen Arbeiten enthaltenen Hinweise auf die gunstigen Festigkeits-Gewichts-Verhaltnisse glas faserverstarkter Kunststoffe, haben sich schon haufig Leichtbaukonstrukteure die Frage vorgelegt, ob nicht viele der bisher aus Metall oder Holz gefertigten Bauteile vorteilhaft aus Glasfaserkunststoff hergestellt werden konnten, zumal die technologischen Eigenarten der Glasfaserkunststoffe Ersparnisse an Betriebs mitteln und Lohnkosten in Aussicht stellen. Ein Grund dafur, dass trotzdem die Anwendung von Glasfaserkunststoff als tragender Werkstoff in hochbeanspruchten Konstruktionsteilen, beispielsweise im Fahrzeug- und Flugzeugbau, bisher auf Einzelfalle beschrankt blieb, liegt anscheinend darin, dass dem Konstrukteur keine garantierten Festigkeitswerte oder zulassigen Spannungen angegeben werden konnen, wie er es bei der Ver wendung von Halbzeugen aus metallischem Werkstoff gewohnt ist. Die Festig keit von Holzern kann zwar auch erheblichen Schwankungen unterliegen, jedoch konnen durch eine Eingangskontrolle im Festigkeitslabor des Betriebes die Eigenschaften einer Holzlieferung eingegrenzt werden und dem Konstrukteur somit zumindest ungefahre Festigkeitswerte des zur Verarbeitung gelangenden Werkstoffes an die Hand gegeben werden. Im Gegensatz dazu entsteht die Festigkeit des Glasfaserkunststoffes erst bei der Fertigung des Bauteiles. Die Festigkeit des Glasfaser-Kunstharz-Verbundstoffes wird beeinflusst durch die Art des Fasermaterials und des Kunstharzbindemittels, die anteilmassigen Mengen beider Stoffe, die Orientierung der Fasern, die Variablen des Hartungsprozesses und noch manche andere Verarbeitungsbedingungen. Eine Kontrolle der mecha nischen Eigenschaften ist demzufolge nur noch an Probeabschnitten moglich, die dem fertigen Bauteil entnommen werden, oder an solchen Proben, die unter sorgfaltiger Beachtung aller Einflussgrossen unter gleichen Bedingungen wie das Bauteil selbst hergestellt werden."
