Points Of View

Abstract In the year 1839, Goodyear discovered that, on treatment with sulfur at elevated temperatures, natural rubber loses its plasticity and becomes elastic. Around the time of World War I, it was discovered that the reaction of the sulfur with the unsaturated rubber hydrocarbons could be promoted by the action of so-called vulcanization accelerators. The reaction then takes place not only faster and at lower temperatures but, in addition, one also needs less sulfur and the vulcanizates acquire considerably better technical properties. Accordingly a tremendous number of compounds have been examined as accelerators of vulcanization and much effort has been applied to develop accelerators with the most satisfactory properties. Today, accelerators are known which permit vulcanization at room temperature. In the past, the mechanism of accelerator action has been studied mostly with the methods of organic and physical chemistry. In the following, an attempt will be made to consider the problem from the viewpoint of the inorganic chemist. One can attempt to interpret the catalysis from two points of view. Either the reactivity of the unsaturated natural rubber hydrocarbon is enhanced, or the sulfur will be converted into a more reactive form. Twiss concluded from his investigations that the latter possibility is the more likely. Subsequently, this assumption has been supported by further observations. In particular, the discovery of Peachey pointed in this direction, since natural rubber is vulcanizable at room temperature if it is treated successively with hydrogen sulfide and sulfur dioxide gases. The sulfur which is formed by this reaction is in the nascent state and is very reactive.

The article analyzes physical and physiological problems caused by fashionable clothing in the mid-18th to early 20th cc. that shaped people’s appearances and lifestyles in the past. Affecting the skeletal system and the functioning of internal organs and brain in particular and causing various illnesses, these problems went largely unrecognized by contemporaries, including writers, but would inevitably surface in literary works as part and parcel of everyday life. Without understanding their role, one may struggle to comprehend not only plot twists and characters’ motivations but also the mentality of the bygone era as portrayed in fiction. Chronologically, the research covers the period from the mid-18th c. to World War I. The author only focuses on so-called respectable society (a very tentative term that covers members of the aristocracy and other classes with comparable lifestyles), since it was this group which drew the most attention from fiction writers of the period. The scholar chose to concentrate on the kind of daily realia of ‘noble society’ that permeate works by Russian, English, French and, to some extent, German authors, considered most prominent in Europe at the time.

The Subject

The fate of Hungarian minorities in East Central Europe has been one of the most neglected subjects in the Western scholarly world. For the past fifty years the subject—at least prior to the late 1980s—was taboo in the successor states (except Yugoslavia), while in Hungary itself relatively few scholars dared to publish anything about this issue till the early 1980s. In the West, it was just not faddish, since most East European and Russian Area studies centers at American, French and English universities tended to think of the territorial status quo as “politically correct.” The Hungarian minorities, on the other hand, were a frustrating reminder that indeed the Entente after World War I, and the Allies after World War II, made major mistakes and significantly contributed to the pain and anguish of the peoples living in this region of the “shatter zone.”

Belle Époque

It was a happy notion on the part of the Costume Society to devote a symposium to La Belle Epoque. The phrase is now generally accepted as covering a period of about twenty-five years, from 1890 to the outbreak of World War I, and although it was by no means "belle" in some of its aspects, it does appear, from many points of view, to have been one of those "enchanted islands in the sea of Time" to which we look back with nostalgia. It has been called the triumph of "High Life", the last good time of the upper classes, the "Garden Party and Casino Period" when English summers were without a cloud and when winter came — well! there was always "Monty".

This concluding chapter offers a review of the key notions developed in the earlier chapters and draws upon this enhanced understanding to offer an explanation for why camping's popularity has begun to waver. Despite camping's strong and pervasive popularity today, the zenith of its national appeal occurred in the past. It is impossible to precisely quantify such trends, but camping's cultural significance appears to have peaked with the explosion of auto campers who hit the motor-camping trail during the decade following World War I. This heightened and widespread popularity should be understood as a reflection of the continuing and rapid urbanization that was sweeping through America, transforming it from a largely rural country in 1910 to a distinctly urban one by 1930.

This chapter focuses on the use of propaganda during times of war, prejudice, and political unrest. Part one distinguishes between persuasion and one of its forms, propaganda. The meaning-in-use of the term ‘propaganda' is essential to understanding its use over time. Part two presents relevant examples of propaganda from the past several centuries in the United States and Europe. These examples include episodes from World War I and II, among others. Propaganda is not a new tool of persuasion, and learning about its use in the past provides a comparison that helps in understanding its use in the present and future. Part three looks at recent examples of how propaganda occurs in actual use in online terrorist mediums by Al-Qaeda and by the Islamic State in Iraq and Syria (ISIS).

The book closes with a short glimpse into the history of Jewish veterans after 1945, as the survivors of the camps returned to Germany, outlining ruptures and continuities in comparison with the pre-Nazi period. Jewish veterans imposed different narratives on their experiences under National Socialism. As the past receded into the distance, it became a concern for the survivors to engage with the past, which they variously looked back on with nostalgia, disillusionment, or bitter anger. Although National Socialism threatened to erase everything that Jewish veterans of World War I had achieved and sacrificed, sought to destroy the identity they had constructed as soldiers in the service of the nation, as well as bonds with gentile Germans that had been forged under fire during the war, threatened to sever their connections to the status they had earned as soldiers of the Great War and defenders of the fatherland, their minds, their values and their character remained intact. Jewish veterans preserved their sense of German identity.

Gains And Losses

Abstract This roundtable offers four diverse perspectives on Peter Jackson’s innovative and controversial World War I documentary film They Shall Not Grow Old (2018). Jackson’s film breaks the mold of the documentary genre in its manipulation and montage of the visual and audio archives held at the Imperial War Museum in London. Yet he puts his technical virtuosity and resources at the service of a very traditional interpretation of the war, focusing almost entirely on the experience of young Englishmen on the Western Front. Scholars Santanu Das, Susan R. Grayzel, Jessica Meyer, and Catherine Robson offer their reflections on both the gains and losses of Jackson’s paradoxical original use of historical documents and old-fashioned rendering of the war’s experiential elements. They consider, respectively, the experience of colonial troops, the place of women in the war, and Jackson’s creative, if controversial, interpretation of the visual and aural archive.

Hone Kouka's historical plays Nga Tangata Toa and Waiora, created and produced in Aotearoa/New Zealand, one set in the immediate aftermath of World War I, and the other during the great Māori urban migrations of the 1960s, provide fresh insights into the way in which individual Māori responded to the tremendous social disruptions they experienced during the twentieth century. Much like the Māori orator who prefaces his formal interactions with a statement of his whakapapa (genealogy), Kouka reassembles the bones of both his ancestors, and those of other Māori, by demonstrating how the present is constructed by the past, offering a view of contemporary Māori identity that is traditional and modern, rural and urban, respectful of the past and open to the future.

Formal Rationality

One of the challenges in writing about the history of American law and political economy is determining the proper amount of historical context necessary to make sense of past institutional and organizational change. Where to begin and end a historical narrative and how much to include about the broader social, cultural, political, and economic conditions of a particular place and time are, of course, questions that accompany any attempt to reconstruct the past. How one addresses these issues invariably shapes the motives and intentions that can be ascribed to historical figures. In their eloquent and thoughtful comments, Christopher Capozzola and Michael Bernstein have urged me to think more carefully about these issues, about where my story begins and ends, about the broader social, political, and material circumstances that animated World War I state-building, and about the seemingly apolitical ideas and actions of the Treasury lawyers who are the center of “Lawyers, Guns, and Public Moneys.”

Intellectual Movement

In this article, Gregory Stroud considers the modern ruin as a site of common urban conversation and identity for large, diverse, and otherwise fractious populations of Petersburg and Moscow residents. Stroud argues that what began at the turn of the century as a relatively narrow nostalgic intellectual movement anxious over the perceived modern loss of timeless beauty and value exploded with the frustrations of the Christmas holiday during World War I into a common boulevard conversation concerning the loss of holiday, ritual, authenticity, and habit. The failure of the old regime to satisfactorily engage this conversation and to offer meaningful solutions would render such nostalgia into a biting critique of autocracy, mass consumerism, private property, and shopkeeper capitalism.
