Late Twentieth Century

This article addresses the history of how chemists designed syntheses of complex molecules during the mid-to-late twentieth century, and of the relationship between devising, describing, teaching, and computerizing methods of scientific thinking in this domain. It details the development of retrosynthetic analysis, a key method that chemists use to plan organic chemical syntheses, and LHASA (Logic and Heuristics Applied to Synthetic Analysis), a computer program intended to aid chemists in this task. The chemist E. J. Corey developed this method and computer program side-by-side, from the early 1960s through the 1990s. Although the LHASA program never came into widespread use, retrosynthetic analysis became a standard method for teaching and practicing synthetic planning, a subject previously taken as resistant to generalization. This article shows how the efforts of Corey and his collaborators to make synthetic planning tractable to teaching and to computer automation shaped a way of thinking taken up by chemists, unaided by machines. The method of retrosynthetic analysis made chemical thinking (as Corey perceived it) explicit, in accordance with the demands of computing (as Corey and his LHASA collaborators perceived them). This history of automation and method-making in recent chemistry suggests a potentially productive approach to the study of other projects to think on, with, or like machines.

This book is the first detailed history of death and the dead in Africa south of the Sahara. Focusing on a region that is now present-day Ghana, the book explores mortuary cultures and the relationship between the living and the dead over a 400-year period spanning the seventeenth to twentieth centuries. The book considers many questions from the African historical perspective, including why people die and where they go after death, how the dead are buried and mourned to ensure they continue to work for the benefit of the living, and how perceptions and experiences of death and the ends of life have changed over time. From exuberant funeral celebrations encountered by seventeenth-century observers to the brilliantly conceived designer coffins of the late twentieth century, the book shows that the peoples of Ghana have developed one of the world's most vibrant cultures of death. The book explores the unfolding background of that culture through a diverse range of issues, such as the symbolic power of mortal remains and the dominion of hallowed ancestors, as well as the problem of bad deaths, vile bodies, and vengeful ghosts. The book reconstructs a vast timeline of death and the dead, from the era of the slave trade to the coming of Christianity and colonial rule to the rise of the modern postcolonial nation. With an array of written and oral sources, the book richly adds to an understanding of how the dead continue to weigh on the shoulders of the living.

This brief conclusion considers a group of films and videos about cinema made in the late twentieth century. Cinema has always been a favorite topic for filmmakers, and that tendency continued at the turn of the millennium. Rather than frame film as a perpetually modern medium, this work views it as an aging, fragile, and exhausted art, though it also considers the history of cinema as a paradoxical source of innovation and renewal. This conclusion surveys key examples of cinema trained on itself and links this reflexive filmmaking to the era’s dominant themes, including belatedness and nostalgia. A final discussion of the Derek Jarman’s Blue highlights the relationship between surface and depth, aesthetics and history explored in this archaeomodern cinema.

AbstractIn recent years, there has been renewed interest in conceptualising the relationship between oppression and capitalism as well as intense debate over the precise nature of this relationship. No doubt spurred on by the financial crisis, it has become increasingly clear that capitalism, both historically and in the twenty-first century, has had particularly devastating effects for women and people of colour. Intersectionality, which emerged in the late twentieth century as a way of addressing the relationship between race, gender, sexuality and class, has submitted orthodox Marxism to critique for its inattention to the complex dynamics of various social locations; in turn Marxist thinkers in the twenty-first century have engaged with intersectionality, calling attention to the impoverished notion of class and capitalism on which it relies. As intersectionality constitutes perhaps the most common way that contemporary activists and theorists on the left conceive of identity politics, an analysis of intersectionality’s relationship to Marxism is absolutely crucial for historical materialists to understand and consider. This paper looks at the history of intersectionality’s and Marxism’s critiques of one another in order to ground a synthesis of the two frameworks. It argues that in the twenty-first century, we need a robust, Marxist analysis of capitalism, and that the only robust account of capitalism is one articulated intersectionally, one which treats class, race, gender and sexuality as fundamental to capitalist accumulation.

The forest was small by American standards, perhaps fifty or sixty acres, but in the rolling Devon countryside with its parceled fields and narrow, hedge-enclosed lanes, it felt appropriately spacious. I was enjoying the guided tour in one of my favorite parts of the world. The light rain and chilly July breezes felt right; the English ivy carpeting the ground seemed right; the leafy hardwoods looked right (although I didn’t know the species and could easily have been fooled); and the probably medieval bank and ditch running through the woods at right angles to the path gave everything an impressive air of authenticity. The path turned. As we rounded the corner, I saw ahead the darker shade of conifers. Soon we were in the midst of a grove of youthful but already towering California-coast redwoods. A deep silence hung like a benediction over the dark wood, but it was quickly shattered. “I’d give anything to be allowed to cut them down,” said our guide, Stephan, in an angry voice. This incident passed out of my thoughts until weeks later back in New Jersey, when I was reading the chapter on conservation in Oliver Rack-ham’s The History of the Countryside, an account of the origins of Britain’s landscapes, flora, and fauna. The British landscape of the late twentieth century, Rack-ham wrote, is suffering from an acute loss of meaning—the unique messages once conveyed by many historic woodlands, witness to millennia of slow and painstaking change, have been garbled beyond recognition in five or six decades of modern planting, “restoration,” development, and agriculture. The more I read in this remarkable book, surely one of the most profound and eloquent descriptions of people and nature ever written, the more I understood Stephan’s feeling that his Devon woodland had been desecrated by the planting of those redwoods. I also began to understand how little I knew about the long discourse between people and trees in Britain, where the history of the relationship is probably as well documented as in any place on earth.

URBAN DISPLACEMENT AND LOW-INCOME COMMUNITIES: THE CASE OF THE AMERICAN CITY FROM THE LATE TWENTIETH CENTURY

How can urban redevelopment benefit existing low-income communities? The history of urban redevelopment is one of disruption of poor communities. Renewal historically offered benefits to the place while pushing out the people. In some cases, displacement is intentional, in others it is unintentional. Often, it is the byproduct of the quest for profits. Regardless of motives, traditional communities, defined by cultural connections, are often disrupted. Disadvantaged neighborhoods include vacant units, which diminish the community and hold back investment. In the postwar period, American cities entered into a program of urban renewal. While this program cleared blight, it also drove displacement among the cities’ poorest and was particularly hard on minority populations clustered in downtown slums. The consequences of these decisions continue to play out today. Concentration of poverty is increasing and American cities are becoming more segregated. As neighborhoods improve, poorer residents are uprooted and forced into even more distressed conditions, elsewhere. This paper examines the history of events impacting urban communities. It further reviews the successes and failures of efforts to benefit low-income communities.

Despite the central importance of festival and devotional piety to premodernMuslims, book-length studies in this field have been relatively rare.Katz’s work, The Birth of the Prophet Muhammad, represents a tour-deforceof critical scholarship that advances the field significantly both throughits engagement with textual sources from the formative period to the presentand through its judicious use of theoretical tools to analyze this material. Asits title suggests, the work strives to explore how Muslims have alternativelypromoted and contested the commemoration of the Prophet’s birth atdifferent points in history, with a particular emphasis on how the devotionalistapproach, which was prominent in the pre-modern era, fell out of favoramong Middle Eastern Sunnis in the late twentieth century. Aimed primarilyat specialists in Middle Eastern and Islamic studies, especially scholarsof history, law, and religion, this work is recommended to anyone interestedin the history of Muslim ritual, the history of devotion to the Prophet, andthe interplay between normative and non-normative forms ofMuslim beliefand practice ...

Like the tableau vivant, the cinematic still life experienced a stunning revival and reinvention in the late twentieth century. In contrast to the stereotypically postmodern overload of images, the still life in film initiates a moment of repose and contemplation within a medium more often defined by the forward rush of moving pictures. It also involves a profound meditation on the relationship between images and objects consistent with practices as diverse as the Spanish baroque still life and the Surrealist variation on the genre. With the work of Terence Davies and Alain Cavalier’s Thérèse (1986) as its primary touchstones, this chapter situates this renewed interest in the cinematic still life within the context of both the late twentieth-century cinema of painters and a socially oriented art cinema that focuses on marginal people and overlooked objects rather than the hegemonic historical narratives also undergoing a revival at the time.

The Myth of the Perfect Pregnancy is a history of why Americans came to have the unrealistic expectation of perfect pregnancies and to mourn even very early miscarriages. The introduction explains that miscarriage is a common phenomenon and a natural part of healthy women’s childbearing: approximately 20 percent of confirmed pregnancies spontaneously miscarry, mostly in the first months of gestation. Eight topical chapters describe childbearing and pregnancy loss in colonial America; the rise of birth control from the late eighteenth century to the present; changes in parenting from the early nineteenth century to the present that increasingly focused attention on the emotional relationship between parent and child; the twentieth-century rise of prenatal care and maternal education about embryonic growth; the twentieth-century blossoming of a consumer culture that marketed baby items to pregnant women; the abortion debates from the mid-twentieth century to the present; the late twentieth-century introduction of obstetric ultrasound and its evolution into a pregnancy ritual of “meeting the baby” as early as eight weeks’ gestation; and the late twentieth-century introduction of home pregnancy testing and the identification of pregnancy as early as several days before a missed period. The conclusion offers suggestions for how women and their families, health-care providers, and the maternity care industry can better handle pregnancy and address miscarriage.

AbstractIn response to the contemporary ecological movement, ecological perspectives have become a significant theme in the theology of creation. This paper asks whether antecedents to this growing significance might predate the concerns of our times and be discernible within the diverse interests of nineteenth-century Anglican thinking. The means used here to examine this possibility is a close reading of B. F. Westcott's ‘Gospel of Creation’. This will be contextualized in two directions: first with reference to the understanding of the natural world in nineteenth-century English popular thought, and secondly with reference to the approach taken to the doctrine of creation by three late twentieth-century Anglican writers, two concerned with the relationship between science and theology in general, and a third concerned more specifically with ecology.

This essay by Richard Schechner dedicated to a mythical figure of the theater of the late twentieth century; a work of critical reconstruction that has contributed decisively to consolidating the legacy of Grotowski, just a few months after his death. In addition to fixing some essential terms of the vocabulary, together with the contents and the periodization of the Grotowskian work (aspects that Grotowski in life were entrusted exclusively to oral transmission), the essay retraces the formation of Grotowski, the aspects linked to his character, the specific forms of his research and his transmission of knowledge, the exercise of leadership, the role of his collaborators, the sources, the mystical side, his relationship with the spirit of time, the importance (and weakness) of his opera, in the history of twentieth century theater.
