Academic literature on the topic 'Richard M Hare'

According to John Flete, the fifteenth-century historian of Westminster Abbey, Abbot Richard de Berkyng (d. 1246) bequeathed to the Abbey two curtains or dorsalia which he had procured for the choir, depicting the story of the Saviour and St Edward. Nothing is known about the appearance of these textiles; but they were presumably of fine quality, befitting the patronage of a Treasurer of England, and were evidently intended to hang in the choir stalls. There they remained until after the Dissolution. According to a sixteenth-century commentary with transcriptions of the original texts in the hangings by Robert Hare, discovered by M. R. James (Gonville and Caius College, Cambridge, MS 391 [611], they were of ‘faire arras worke’, and so were tapestries rather than embroideries; they were also described as ‘wrought in the cloth of Arras’ by Weever in 1631. They hung in the church until 1644, whence they were removed to the chamber of the House of Commons in the Palace; according to Brayley ‘a large remnant’ of the scene of the Circumcision was still preserved in the Jerusalem Chamber at the Abbey in the early nineteenth century. The tapestries were one of the most extensive recorded instances of English thirteenth-century textile production. They provide evidence too for a genre of monastic choir decoration analogous to the lost Old Testament narratives in the choir at Bury St Edmund's and the typological pictures formerly adorning the choir-stalls of Peterborough Abbey. Moreover, they anticipate the mixture of purely narrative material in the surviving fourteenth-century paintings above the dossals of the choir stalls of Cologne Cathedral, and especially the tapestries depicting the lives of St Piat and St Eleutherius from the choir of Tournai Cathedral, Arras work dated 1402.

Abstract Get this: PhDs are hard. But PhDs can be hard for the wrong reasons. A recent event held by the RAS's Early Career Network Committee identified a host of unnecessary energy-drains that should be avoided for a more profitable PhD experience. By Dominic M.

El presente artículo está basado en la exposición de M. Michel Richard, en el 3rd International Architecture Workshop 2017: Tourisme et patrimoine. Le territoire de Roquebrune-Cap Martin, realizado por la Designing Heritage Tourism Landscape Network, en septiembre de 2017, en Francia. Como Presidente, entonces, de la Fundación Le Corbusier y experto en su obra y en el trabajo de preservación que esta implica, Michel Richard llama a reflexionar sobre los desafíos que la apertura al turismo de masas presupone para dichas obras. Tal es el caso de las que fueron tema del Workshop antes mencionado (el Cabanon, la Villa E-1027, las Unités de Camping, el estudio de Le Corbusier), y que fueron concebidas como espacios para la vida privada, como arquitecturas íntimas. Richard hace foco en las contradicciones entre la necesidad de hacer conocer el patrimonio (y los potenciales recursos que esta acción proporciona para la conservación del mismo) y la obligación de protegerlo, a su vez, de las consecuencias lógicas del acceso del público.

Background: Ibrutinib, a small molecule inhibitor of Bruton's Tyrosine Kinase (BTK) is approved for use in a variety of lymphomas. Priced at $130,000/year, Ibrutinib imposes a significant financial burden on patients and society[1]. The study serving as the basis for the currently approved dose [2] demonstrated >95% BTK receptor occupancy at a dose of 2.5 mg/kg. Data suggests that lower doses of Ibrutinib are equally effective[3] and dose reductions[4, 5] do not compromise outcome. Objective: To evaluate patient outcomes and cost savings with clinically indicated low dose (LD) of Ibrutinib in a community practice in hematological malignancies. Method: All patients treated with standard and LD Ibrutinib between January 2014 and July 2020 were identified. Reason for dose modification and best responses were abstracted. Patients with inadequate follow up or less than a week of treatment were excluded from the analysis. Responses were defined based on the iwCLL response criteria for Chronic Lymphocytic Leukemia (CLL), Lugano criteria for Non-Hodgkin's Lymphoma and International Working Group on Waldenström's Macroglobulinemia (WM), as applicable. To calculate drug cost at lower doses of Ibrutinib, cumulative number of patient-months on different dose levels of ibrutinib was calculated by adding the number of months each patient had remained at the dose level at the time of data cut-off. Drug cost at LD was calculated by multiplying monthly wholesale acquisition price for different dose levels of ibrutinib by the cumulative number of patient-months at that dose level. Cost differential between actual drug cost and projected drug cost at full dose was calculated. Results: 98 patients were identified. 10 were excluded from the analysis based on drug not started (3), inadequate follow-up (3), other (4). Median length of follow up for all patients was 20 months (4-70 months) and on LD Ibrutinib 12.5 months (1-60 months). 10 and 12 patients received 140 mg and 280 mg of Ibrutinib respectively due to side effects. 61 patients had CLL, 9 WM, 15 mantle cell lymphoma (MCL), and 2 marginal zone lymphoma (MZL). Response rates were similar across diagnoses and dose levels (TABLE 1 and FIGURE 1). Progressive disease (PD) at low dose was seen in 2 CLL patients with complex cytogenetics, deletion 17p and extensive prior therapy. The one WM patient with PD had been extensively pretreated. Cumulative patient-months at the 140 mg and 280 mg dose levels of Ibrutinib was 177 and 123 months respectively. Drug cost for the 140 mg and 280 mg Ibrutinib cohorts were $712,276 and $989,943 respectively, for a total cost of $1,702,219. Potential drug cost for the 420 or 560 mg dose of Ibrutinib for the same duration of therapy was $3,621,828. Cumulative cost avoidance on LD Ibrutinib was $1,919, 608. Conclusions: Clinically indicated low dose Ibrutinib was equally effective and produced significant cost savings. References: 1. Qiushi Chen, N.J., Turgay Ayer, William G. Wierda, Christopher R.

This latest addition to publisher M. E. Sharpe's Australian National University contemporary China books series comes with a blurb that sends a powerful message of intimidation to the weary reviewer. In it, Richard Baum insists that the book's contents amount to “the distilled wisdom and insight of three generations of distinguished China specialists.” Now, who would want to risk stepping on the toes of one's daughter's, one's own and one's mother's generations in ‘the field’ by saying no?

“Study hard what interests you the most in the most undisciplined, irreverent and original manner possible” [ Perfectly Reasonable Deviations from the Beaten Track, Richard P. Feynman, Basic Books, 2005]. Writing original homework problems is a powerful way students of physical acoustics can practice Feynman’s advice. Three problems that involve a broad range of concepts covered in introductory graduate-level physical acoustics courses illustrate how the student-author unleashed his creativity in an undisciplined manner, injected his problems with an irreverent sense of humor, and derived a great sense of originality and ownership over physical acoustics. The problems synthesize David T. Blackstock’s problems 1D-2, 1E-3, 1G-1, 1G-3, 7-6, 10-10, and 10-11 [ Fundamentals of Physical Acoustics, David T. Blackstock, Wiley, 2000], addressing concepts including acoustic intensity, impedance, horns, enclosures, and radiation. [CAG was supported by the ARL:UT Chester M.

Ronald Reagan's contribution to federal Indian policy proved mixed. Remarks by members of his administration recalled the heyday of termination, and Reagan's budget cuts fell hard on Native Americans. Reagan also played to non-Indian backlash by supporting legislation that restricted tribal rights to file claims on land disputes. Still, the administration continued the policy of tribal self-determination, begun under Richard M. Nixon. Reagan signed legislation to restore the Klamaths to federal trust responsibility, to help tribes ““contract out”” to run many federal services themselves, and to recognize and regulate gaming on Indian reservations. Most importantly, Reagan affirmed ““government to government”” relationships between the federal government, states, and tribes. Federal Indian policy mirrored other aspects of U.S. politics in the 1980s, including reductions in domestic spending, white reaction against minority civil rights gains, and the extolling of entrepreneurship. But the administration's ability, and even its willingness, to reverse the trend toward tribal self-determination proved limited.

Throughout his career as moral philosopher Hare has insisted that there is a rational way of arriving at substantive moral judgements. Hare develops this view - first presented in ' The language of morals' (1952) and ' Universalizability' (1955) - into the claim that rational agents are required to adopt utilitarian solutions to moral disputes. In ' Freedom and reason ' (1963) this claim is defended with reference to the view that the formal features of moral language (universalizability and prescriptivity)commit moral agents to a certain method of reasoning, and that this method of reasoning, when conjoined with facts about people's desires and preferences, leads us to accept substantive moral judgements consistent with those required by a form of utilitarianism. This view features throughout Hare's subsequent work, but the argument for it undergoes change. This means change in the defence of the claim that the meta-theory Universal Prescriptivism is consistent with a form of normative utilitarian theory, as this claim is argued for in 'Ethical theory and utilitarianism' (1976) and 'Moral Thinking' (1981). I shall endeavour to trace the chronological development of Hare's thinking, and will concentrate on developments in the argument for a theory of act-utilitarianism. I shall argue that the argument for utilitarianism gives rise to two major problems which arise from a specific feature of the argument, namely, the attempt to run the resolution of bi-lateral and multi-lateral cases of conflict along lines analogous to the resolution of conflict in the single-person case. Hare's argument requires that a decision-maker must identify the person with whom he reverses roles as himself, and that he must be prepared to concede that the things his recipient has good reasons for wanting are also reasons for him to want the same things. I argue that it is not possible to make coherent sense of the identity of the person in the reversed-role situation and that the motivational states a decision -maker is expected to deem 'his own' are not properly states of himself. If I am right, the 'identity'-question sits at the root of a motivational gap in Hare's theory.

This dissertation treats about the relation between information and action in moral judgments. First of all, we explicit the logical problem, called antinomy, present in the descriptive ethics theories which do not admit the prescriptive factor of the moral judgments. Secondly we present the logical problem, called paradox, present in Austin s linguistic theory (which gave rise to the ethical prescriptivism) that does not admit the descriptive factor of moral judgments. After that, we present Hare s theory as synthesis, which gathers descriptive and prescriptive factors, and, because of this, does not make the same mistakes of the theories previously developed. Although, some critics - Geach, Sen and Azevedo accused Hare of being an existential descriptivist. More precisely, Sen and Geach accused him of being descriptivist, whereas Sen and Azevedo accused him of being existentialist. This work shows that those accusations occur because of the failure in the interpretation of the relation between descriptive and prescriptive factors on Hare s formulation about moral judgments. For the author, the supervenience (which guarantees that the moral choices must be the same when the same factual elements are presented) is the fundament of the universalizability (which guarantees that the moral action must be the same independently of the roles played on the moral action). However, these formulations do not prevent that the author of the moral judgment gather more information and start acting differently, which would not be possible for a descriptivist. Because of this, we formulated a symbolic model, which relates cultural pattern, prescribed pattern and value; and, moreover, which shows the temporal aspects and the change aspects. Another issue is about the necessity of the critical thought, for Hare, in the formulation of universal ethics. So, this work will explicit the reasons why Hare cannot be called existential descriptivist.
Esta dissertação trata da relação entre informação e ação nos juízos morais. Primeiramente é explicitado o problema lógico, denominado de antinomia, presentes nas teorias éticas descritivistas que não admitem o fator prescritivo dos juízos morais. Em segundo lugar, é apresentado o problema lógico, denominado de paradoxo, presente na teoria lingüística de Austin (que deu origem ao prescritivismo ético) a qual não admite o fator descritivo dos juízos morais. Posteriormente, a teoria de Hare é apresentada como síntese, que une o fator descritivo e o prescritivo, e que, por isso, não comete os mesmos erros das teorias desenvolvidas anteriormente. Porém, alguns críticos Geach, Sen e Azevedo acusaram Hare de ser um descritivista existencial. Mais precisamente: Sen e Geach o acusaram de ser descritivista; ao passo que Sen e Azevedo o acusaram de ser existencialista. Este trabalho mostra que estas acusações ocorrem pela falha na interpretação da relação entre fator descritivo e prescritivo na formulação de Hare sobre os juízos morais. Para o autor, a superveniência (que garante que as escolhas morais devem ser as mesmas, quando apresentados os mesmos elementos fatuais) é o fundamento da universalizabilidade (que garante que a ação moral deve ser a mesma independente dos papéis representados na ação moral). Mas, essas formulações não impedem que o autor do juízo moral reúna novas informações e passe a agir de forma diferente, o que não seria possível para um descritivista. Por isso, formulamos um modelo simbólico, o qual relaciona padrão cultural, padrão prescrito e valor; e, além disso, que mostra os aspectos temporais e de mudança. Outra questão gira em torno da necessidade do pensamento crítico, para Hare, na formulação de uma ética universal. Dessa forma, neste trabalho ficará explicitado os motivos pelos quais Hare não poder ser chamado de descritivista existencial.

This thesis looks at two theories of universalizability: Immanuel Kant's deontological one and R. M. Hare's utilitarian one. It also looks at criticisms of both theories by David Wiggins. It concludes that his arguments against Hare are decisive because the moral theory that follows from Hare's version of the claim that moral judgements must be universalizable is incompatible with several basic requirements on moral theories. Wiggins' criticism of Kant, on the other hand, centres on a technical point that is overcome by an interpretation of Kant's tests for the universalizability of maxims that is given by Onora Nell. Finally the thesis argues that Kant's rational theory of ethics is superior to Wiggins' subjectivist claims because it both reflects our common sense conception of ethics and provides a rational basis for evaluating moral judgements.

A do-it-yourself manual for culturing nerve cells, complete with recipes and protocols. Because neurons and glia in culture are remarkably similar to those in situ, culture systems make it possible to identify significant cell interactions and to elucidate their mechanisms. This book is in many ways a do-it-yourself manual for culturing nerve cells, complete with recipes and protocols. But it also provides an understanding of the principles behind the protocols. In effect the contributors invite you into their labs and provide much of the information you would obtain from such a visit.The authors of the introductory chapters present the nuts-and-bolts principles of growing nerve cells. The authors of the following chapters discuss the culturing of specific cell types. They explain how their experimental goals have shaped their particular cell culture approach and the advantages and disadvantages of the cell culture systems they have developed. They provide detailed protocols and describe their cultures in practical terms, from when the cells are first plated through the various phases of their development.

Deserted Villages: Perspectives from the Eastern Mediterranean is a collection of case studies examining the abandonment of rural settlements over the past millennium and a half, focusing on modern-day Greece with contributions from Turkey and the United States. Unlike other parts of the world, where deserted villages have benefited from decades of meticulous archaeological research, in the eastern Mediterranean better-known ancient sites have often overshadowed the nearby remains of more recently abandoned settlements. Yet as the papers in this volume show, the tide is finally turning toward a more engaged, multidisciplinary, and anthropologically informed archaeology of medieval and post-medieval rural landscapes. The inspiration for this volume was a two-part colloquium organized for the 2016 Annual Meeting of the Archaeological Institute of America in San Francisco. The sessions were sponsored by the Medieval and Post-Medieval Archaeology Interest Group, a rag-tag team of archaeologists who set out in 2005 with the dual goals of promoting the study of later material and cultural heritage and opening publication venues to the fruits of this research. The introduction to the volume reviews the state of the field and contextualizes the archaeological understanding of abandonment and post-abandonment as ongoing processes. The nine, peer reviewed chapters, which have been substantially revised and expanded since the colloquium, offer unparalleled glimpses into how this process has played out in different places. In the first half, the studies focus on long-abandoned sites that have now entered the archaeological record. In the second half, the studies incorporate archival analysis and ethnographic interviews—alongside the archaeologists’ hyper-attention to material culture—to examine the processes of abandonment and post-abandonment in real time.

This book analyzes U.S. policies toward Latin America during a critical period of the Cold War. Except for the issue of Chile under Salvador Allende, historians have largely ignored inter-American relations during the presidencies of Richard M. Nixon and Gerald R. Ford. This book also offers a way of adding to and challenging the prevailing historiography on one of the most preeminent policymakers in the history of U.S. foreign relations. Scholarly studies on Henry Kissinger and his policies between 1969 and 1977 have tended to survey Kissinger's approach to the world, with an emphasis on initiatives toward the Soviet Union and the People's Republic of China and the struggle to extricate the United States from the Vietnam conflict. This book offers something new—analyzing U.S. policies toward a distinct region of the world during Kissinger's career as national security adviser and secretary of state. The book further challenges the notion that Henry Kissinger dismissed relations with the southern neighbors. The energetic Kissinger devoted more time and effort to Latin America than any of his predecessors—or successors—who served as the national security adviser or secretary of state during the Cold War era. He waged war against Salvador Allende and successfully destabilized a government in Bolivia. He resolved nettlesome issues with Mexico, Peru, Ecuador, and Venezuela. He launched critical initiatives with Panama and Cuba. Kissinger also bolstered and coddled murderous military dictators who trampled on basic human rights. South American military dictators whom Kissinger favored committed international terrorism in Europe and the Western Hemisphere.

Nationalism: Past as Prologue began as a single volume being compiled by Ad Akande, a scholar from South Africa, who proposed it to me as co-author about two years ago. The original idea was to examine how the damaging roots of nationalism have been corroding political systems around the world, and creating dangerous obstacles for necessary international cooperation. Since I (Bruce E. Johansen) has written profusely about climate change (global warming, a.k.a. infrared forcing), I suggested a concerted effort in that direction. This is a worldwide existential threat that affects every living thing on Earth. It often compounds upon itself, so delays in reducing emissions of fossil fuels are shortening the amount of time remaining to eliminate the use of fossil fuels to preserve a livable planet. Nationalism often impedes solutions to this problem (among many others), as nations place their singular needs above the common good. Our initial proposal got around, and abstracts on many subjects arrived. Within a few weeks, we had enough good material for a 100,000-word book. The book then fattened to two moderate volumes and then to four two very hefty tomes. We tried several different titles as good submissions swelled. We also discovered that our best contributors were experts in their fields, which ranged the world. We settled on three stand-alone books:” 1/ nationalism and racial justice. Our first volume grew as the growth of Black Lives Matter following the brutal killing of George Floyd ignited protests over police brutality and other issues during 2020, following the police assassination of Floyd in Minneapolis. It is estimated that more people took part in protests of police brutality during the summer of 2020 than any other series of marches in United States history. This includes upheavals during the 1960s over racial issues and against the war in Southeast Asia (notably Vietnam). We choose a volume on racism because it is one of nationalism’s main motive forces. This volume provides a worldwide array of work on nationalism’s growth in various countries, usually by authors residing in them, or in the United States with ethnic ties to the nation being examined, often recent immigrants to the United States from them. Our roster of contributors comprises a small United Nations of insightful, well-written research and commentary from Indonesia, New Zealand, Australia, China, India, South Africa, France, Portugal, Estonia, Hungary, Russia, Poland, Kazakhstan, Georgia, and the United States. Volume 2 (this one) describes and analyzes nationalism, by country, around the world, except for the United States; and 3/material directly related to President Donald Trump, and the United States. The first volume is under consideration at the Texas A & M University Press. The other two are under contract to Nova Science Publishers (which includes social sciences). These three volumes may be used individually or as a set. Environmental material is taken up in appropriate places in each of the three books. * * * * * What became the United States of America has been strongly nationalist since the English of present-day Massachusetts and Jamestown first hit North America’s eastern shores. The country propelled itself across North America with the self-serving ideology of “manifest destiny” for four centuries before Donald Trump came along. Anyone who believes that a Trumpian affection for deportation of “illegals” is a new thing ought to take a look at immigration and deportation statistics in Adam Goodman’s The Deportation Machine: America’s Long History of Deporting Immigrants (Princeton University Press, 2020). Between 1920 and 2018, the United States deported 56.3 million people, compared with 51.7 million who were granted legal immigration status during the same dates. Nearly nine of ten deportees were Mexican (Nolan, 2020, 83). This kind of nationalism, has become an assassin of democracy as well as an impediment to solving global problems. Paul Krugman wrote in the New York Times (2019:A-25): that “In their 2018 book, How Democracies Die, the political scientists Steven Levitsky and Daniel Ziblatt documented how this process has played out in many countries, from Vladimir Putin’s Russia, to Recep Erdogan’s Turkey, to Viktor Orban’s Hungary. Add to these India’s Narendra Modi, China’s Xi Jinping, and the United States’ Donald Trump, among others. Bit by bit, the guardrails of democracy have been torn down, as institutions meant to serve the public became tools of ruling parties and self-serving ideologies, weaponized to punish and intimidate opposition parties’ opponents. On paper, these countries are still democracies; in practice, they have become one-party regimes….And it’s happening here [the United States] as we speak. If you are not worried about the future of American democracy, you aren’t paying attention” (Krugmam, 2019, A-25). We are reminded continuously that the late Carl Sagan, one of our most insightful scientific public intellectuals, had an interesting theory about highly developed civilizations. Given the number of stars and planets that must exist in the vast reaches of the universe, he said, there must be other highly developed and organized forms of life. Distance may keep us from making physical contact, but Sagan said that another reason we may never be on speaking terms with another intelligent race is (judging from our own example) could be their penchant for destroying themselves in relatively short order after reaching technological complexity. This book’s chapters, introduction, and conclusion examine the worldwide rise of partisan nationalism and the damage it has wrought on the worldwide pursuit of solutions for issues requiring worldwide scope, such scientific co-operation public health and others, mixing analysis of both. We use both historical description and analysis. This analysis concludes with a description of why we must avoid the isolating nature of nationalism that isolates people and encourages separation if we are to deal with issues of world-wide concern, and to maintain a sustainable, survivable Earth, placing the dominant political movement of our time against the Earth’s existential crises. Our contributors, all experts in their fields, each have assumed responsibility for a country, or two if they are related. This work entwines themes of worldwide concern with the political growth of nationalism because leaders with such a worldview are disinclined to co-operate internationally at a time when nations must find ways to solve common problems, such as the climate crisis. Inability to cooperate at this stage may doom everyone, eventually, to an overheated, stormy future plagued by droughts and deluges portending shortages of food and other essential commodities, meanwhile destroying large coastal urban areas because of rising sea levels. Future historians may look back at our time and wonder why as well as how our world succumbed to isolating nationalism at a time when time was so short for cooperative intervention which is crucial for survival of a sustainable earth. Pride in language and culture is salubrious to individuals’ sense of history and identity. Excess nationalism that prevents international co-operation on harmful worldwide maladies is quite another. As Pope Francis has pointed out: For all of our connectivity due to expansion of social media, ability to communicate can breed contempt as well as mutual trust. “For all our hyper-connectivity,” said Francis, “We witnessed a fragmentation that made it more difficult to resolve problems that affect us all” (Horowitz, 2020, A-12). The pope’s encyclical, titled “Brothers All,” also said: “The forces of myopic, extremist, resentful, and aggressive nationalism are on the rise.” The pope’s document also advocates support for migrants, as well as resistance to nationalist and tribal populism. Francis broadened his critique to the role of market capitalism, as well as nationalism has failed the peoples of the world when they need co-operation and solidarity in the face of the world-wide corona virus pandemic. Humankind needs to unite into “a new sense of the human family [Fratelli Tutti, “Brothers All”], that rejects war at all costs” (Pope, 2020, 6-A). Our journey takes us first to Russia, with the able eye and honed expertise of Richard D. Anderson, Jr. who teaches as UCLA and publishes on the subject of his chapter: “Putin, Russian identity, and Russia’s conduct at home and abroad.” Readers should find Dr. Anderson’s analysis fascinating because Vladimir Putin, the singular leader of Russian foreign and domestic policy these days (and perhaps for the rest of his life, given how malleable Russia’s Constitution has become) may be a short man physically, but has high ambitions. One of these involves restoring the old Russian (and Soviet) empire, which would involve re-subjugating a number of nations that broke off as the old order dissolved about 30 years ago. President (shall we say czar?) Putin also has international ambitions, notably by destabilizing the United States, where election meddling has become a specialty. The sight of Putin and U.S. president Donald Trump, two very rich men (Putin $70-$200 billion; Trump $2.5 billion), nuzzling in friendship would probably set Thomas Jefferson and Vladimir Lenin spinning in their graves. The road of history can take some unanticipated twists and turns. Consider Poland, from which we have an expert native analysis in chapter 2, Bartosz Hlebowicz, who is a Polish anthropologist and journalist. His piece is titled “Lawless and Unjust: How to Quickly Make Your Own Country a Puppet State Run by a Group of Hoodlums – the Hopeless Case of Poland (2015–2020).” When I visited Poland to teach and lecture twice between 2006 and 2008, most people seemed to be walking on air induced by freedom to conduct their own affairs to an unusual degree for a state usually squeezed between nationalists in Germany and Russia. What did the Poles then do in a couple of decades? Read Hlebowicz’ chapter and decide. It certainly isn’t soft-bellied liberalism. In Chapter 3, with Bruce E. Johansen, we visit China’s western provinces, the lands of Tibet as well as the Uighurs and other Muslims in the Xinjiang region, who would most assuredly resent being characterized as being possessed by the Chinese of the Han to the east. As a student of Native American history, I had never before thought of the Tibetans and Uighurs as Native peoples struggling against the Independence-minded peoples of a land that is called an adjunct of China on most of our maps. The random act of sitting next to a young woman on an Air India flight out of Hyderabad, bound for New Delhi taught me that the Tibetans had something to share with the Lakota, the Iroquois, and hundreds of other Native American states and nations in North America. Active resistance to Chinese rule lasted into the mid-nineteenth century, and continues today in a subversive manner, even in song, as I learned in 2018 when I acted as a foreign adjudicator on a Ph.D. dissertation by a Tibetan student at the University of Madras (in what is now in a city called Chennai), in southwestern India on resistance in song during Tibet’s recent history. Tibet is one of very few places on Earth where a young dissident can get shot to death for singing a song that troubles China’s Quest for Lebensraum. The situation in Xinjiang region, where close to a million Muslims have been interned in “reeducation” camps surrounded with brick walls and barbed wire. They sing, too. Come with us and hear the music. Back to Europe now, in Chapter 4, to Portugal and Spain, we find a break in the general pattern of nationalism. Portugal has been more progressive governmentally than most. Spain varies from a liberal majority to military coups, a pattern which has been exported to Latin America. A situation such as this can make use of the term “populism” problematic, because general usage in our time usually ties the word into a right-wing connotative straightjacket. “Populism” can be used to describe progressive (left-wing) insurgencies as well. José Pinto, who is native to Portugal and also researches and writes in Spanish as well as English, in “Populism in Portugal and Spain: a Real Neighbourhood?” provides insight into these historical paradoxes. Hungary shares some historical inclinations with Poland (above). Both emerged from Soviet dominance in an air of developing freedom and multicultural diversity after the Berlin Wall fell and the Soviet Union collapsed. Then, gradually at first, right wing-forces began to tighten up, stripping structures supporting popular freedom, from the courts, mass media, and other institutions. In Chapter 5, Bernard Tamas, in “From Youth Movement to Right-Liberal Wing Authoritarianism: The Rise of Fidesz and the Decline of Hungarian Democracy” puts the renewed growth of political and social repression into a context of worldwide nationalism. Tamas, an associate professor of political science at Valdosta State University, has been a postdoctoral fellow at Harvard University and a Fulbright scholar at the Central European University in Budapest, Hungary. His books include From Dissident to Party Politics: The Struggle for Democracy in Post-Communist Hungary (2007). Bear in mind that not everyone shares Orbán’s vision of what will make this nation great, again. On graffiti-covered walls in Budapest, Runes (traditional Hungarian script) has been found that read “Orbán is a motherfucker” (Mikanowski, 2019, 58). Also in Europe, in Chapter 6, Professor Ronan Le Coadic, of the University of Rennes, Rennes, France, in “Is There a Revival of French Nationalism?” Stating this title in the form of a question is quite appropriate because France’s nationalistic shift has built and ebbed several times during the last few decades. For a time after 2000, it came close to assuming the role of a substantial minority, only to ebb after that. In 2017, the candidate of the National Front reached the second round of the French presidential election. This was the second time this nationalist party reached the second round of the presidential election in the history of the Fifth Republic. In 2002, however, Jean-Marie Le Pen had only obtained 17.79% of the votes, while fifteen years later his daughter, Marine Le Pen, almost doubled her father's record, reaching 33.90% of the votes cast. Moreover, in the 2019 European elections, re-named Rassemblement National obtained the largest number of votes of all French political formations and can therefore boast of being "the leading party in France.” The brutality of oppressive nationalism may be expressed in personal relationships, such as child abuse. While Indonesia and Aotearoa [the Maoris’ name for New Zealand] hold very different ranks in the United Nations Human Development Programme assessments, where Indonesia is classified as a medium development country and Aotearoa New Zealand as a very high development country. In Chapter 7, “Domestic Violence Against Women in Indonesia and Aotearoa New Zealand: Making Sense of Differences and Similarities” co-authors, in Chapter 8, Mandy Morgan and Dr. Elli N. Hayati, from New Zealand and Indonesia respectively, found that despite their socio-economic differences, one in three women in each country experience physical or sexual intimate partner violence over their lifetime. In this chapter ther authors aim to deepen understandings of domestic violence through discussion of the socio-economic and demographic characteristics of theit countries to address domestic violence alongside studies of women’s attitudes to gender norms and experiences of intimate partner violence. One of the most surprising and upsetting scholarly journeys that a North American student may take involves Adolf Hitler’s comments on oppression of American Indians and Blacks as he imagined the construction of the Nazi state, a genesis of nationalism that is all but unknown in the United States of America, traced in this volume (Chapter 8) by co-editor Johansen. Beginning in Mein Kampf, during the 1920s, Hitler explicitly used the westward expansion of the United States across North America as a model and justification for Nazi conquest and anticipated colonization by Germans of what the Nazis called the “wild East” – the Slavic nations of Poland, the Baltic states, Ukraine, and Russia, most of which were under control of the Soviet Union. The Volga River (in Russia) was styled by Hitler as the Germans’ Mississippi, and covered wagons were readied for the German “manifest destiny” of imprisoning, eradicating, and replacing peoples the Nazis deemed inferior, all with direct references to events in North America during the previous century. At the same time, with no sense of contradiction, the Nazis partook of a long-standing German romanticism of Native Americans. One of Goebbels’ less propitious schemes was to confer honorary Aryan status on Native American tribes, in the hope that they would rise up against their oppressors. U.S. racial attitudes were “evidence [to the Nazis] that America was evolving in the right direction, despite its specious rhetoric about equality.” Ming Xie, originally from Beijing, in the People’s Republic of China, in Chapter 9, “News Coverage and Public Perceptions of the Social Credit System in China,” writes that The State Council of China in 2014 announced “that a nationwide social credit system would be established” in China. “Under this system, individuals, private companies, social organizations, and governmental agencies are assigned a score which will be calculated based on their trustworthiness and daily actions such as transaction history, professional conduct, obedience to law, corruption, tax evasion, and academic plagiarism.” The “nationalism” in this case is that of the state over the individual. China has 1.4 billion people; this system takes their measure for the purpose of state control. Once fully operational, control will be more subtle. People who are subject to it, through modern technology (most often smart phones) will prompt many people to self-censor. Orwell, modernized, might write: “Your smart phone is watching you.” Ming Xie holds two Ph.Ds, one in Public Administration from University of Nebraska at Omaha and another in Cultural Anthropology from the Chinese Academy of Social Sciences, Beijing, where she also worked for more than 10 years at a national think tank in the same institution. While there she summarized news from non-Chinese sources for senior members of the Chinese Communist Party. Ming is presently an assistant professor at the Department of Political Science and Criminal Justice, West Texas A&M University. In Chapter 10, analyzing native peoples and nationhood, Barbara Alice Mann, Professor of Honours at the University of Toledo, in “Divide, et Impera: The Self-Genocide Game” details ways in which European-American invaders deprive the conquered of their sense of nationhood as part of a subjugation system that amounts to genocide, rubbing out their languages and cultures -- and ultimately forcing the native peoples to assimilate on their own, for survival in a culture that is foreign to them. Mann is one of Native American Studies’ most acute critics of conquests’ contradictions, and an author who retrieves Native history with a powerful sense of voice and purpose, having authored roughly a dozen books and numerous book chapters, among many other works, who has traveled around the world lecturing and publishing on many subjects. Nalanda Roy and S. Mae Pedron in Chapter 11, “Understanding the Face of Humanity: The Rohingya Genocide.” describe one of the largest forced migrations in the history of the human race, the removal of 700,000 to 800,000 Muslims from Buddhist Myanmar to Bangladesh, which itself is already one of the most crowded and impoverished nations on Earth. With about 150 million people packed into an area the size of Nebraska and Iowa (population less than a tenth that of Bangladesh, a country that is losing land steadily to rising sea levels and erosion of the Ganges river delta. The Rohingyas’ refugee camp has been squeezed onto a gigantic, eroding, muddy slope that contains nearly no vegetation. However, Bangladesh is majority Muslim, so while the Rohingya may starve, they won’t be shot to death by marauding armies. Both authors of this exquisite (and excruciating) account teach at Georgia Southern University in Savannah, Georgia, Roy as an associate professor of International Studies and Asian politics, and Pedron as a graduate student; Roy originally hails from very eastern India, close to both Myanmar and Bangladesh, so he has special insight into the context of one of the most brutal genocides of our time, or any other. This is our case describing the problems that nationalism has and will pose for the sustainability of the Earth as our little blue-and-green orb becomes more crowded over time. The old ways, in which national arguments often end in devastating wars, are obsolete, given that the Earth and all the people, plants, and other animals that it sustains are faced with the existential threat of a climate crisis that within two centuries, more or less, will flood large parts of coastal cities, and endanger many species of plants and animals. To survive, we must listen to the Earth, and observe her travails, because they are increasingly our own.

Abstract A series of philosophers including Richard Hare, Kurt Baier, Marcus Singer, David Cummiskey, and Derek Parfit, have attempted to find common ground between Kantianism and utilitarianism, or more broadly what is now called (after Elizabeth Anscombe) consequentialism. On the basis of his analysis of moral language, Hare advocated what he called “universal prescriptivism,” which sounds Kantian, but also argued that what anyone would prescribe for everyone is a form of utilitarianism. Baier’s “moral point of view” requires everyone to override self-interest in favor of universally acceptable reasons, but finds the content of the latter in what is required to preserve human society. Singer argued for a Kant-inspired “generalization” principle that “what is right (or wrong) for one person must be right (or wrong) for any similar person in similar circumstances,” but also argued that we could determine what would satisfy this constraint by considering the “desirability” of the consequences of proposed actions. Cummiskey stayed closer to Kant in presenting a consequentialist analysis of the implications of the Formula of Humanity. Finally, Parfit argued that utilitarianism best stated the content that would be yielded either by a Kantian universalization procedure or by T. M. Scanlon’s “contractualist” principle that what is right is what no one could reasonably reject.

Abstract In the past twenty-five years or so a number of philosophers have argued for the possibility of full-blown moral dilemmas: cases in which all of the agent’s alternatives, through no fault of his own, turn out to be morally wrong. Other authors have attempted to dismiss such cases as undermining the rational coherency of ethics, on the modern conception of ethics as essentially a system of rules meant to guide action. A good specimen of the sort of case at issue in the literature is provided by one of Michael Walzer’s examples in his contribution to a 1973 symposium on the rules of war with Thomas Nagel, Richard Brandt, and R. M. Hare.1 The case assumes that torture is necessary to get a terrorist to give away the whereabouts of bombs set to go off throughout the city but that torture still remains wrong under these circumstances-along with the agent’s only other alternative, which involves letting the bombs destroy many innocent civilians.

Abstract small it couldn’t have made any difference. Perhaps he was too ill for anything to have saved him. His poor body had taken such a beating in his short life-he was forty-eight-and his resistance was very low. He remained unconscious all the time he was in the hospital, and on the fourth night, just as the lights went out for a wartime practice blackout, he died. (Later when M-G-M made a movie called Words and Music about Dick and Larry, they fictionalized another ending for the story because they said no one would believe what really happened. It was too dramatic for Hollywood.) in some respects the forgotten Chee-Chee marks a crossroads in the career of Rodgers and Hart. In Rodgers’s four letters to Dorothy from September 1 to 17, 1928, the first letter written in New York and the others during the Philadelphia tryouts, he spoke proudly about this innovative work: “No matter what happens to us commercially we’ve accomplished what we’ve been after for years:’ Throughout these letters Rodgers conveys a mixture of enthusiasm and trepidation about how the work would be received. On September 7 he wrote that “there are doubts as to its financial future and its reception by the New York press... but I know we’ve done something fine at last:’ On September 12 he wrote that “the show is the best musical thing I’ve ever seen:’ In the final letter he emphasized the varied press response and the views of the letter-writing public. Although no future Rodgers and Hart show came close to matching the popular debacle of Chee-Chee, the next three years were marked by less artistic daring (e.g., Spring Is Here, 1929), a sharp drop in quantity (a total of four shows), and only one unqualified popular success, the London production.

Set against the backdrop of the presidential election of 1972 and Republican Richard M. Nixon’s calculated support for the federal Coastal Zone Management Act, the failed effort in California to obtain passage of a statewide law regulating the shore is detailed, followed by enactment of Proposition 20 and the California Coastal Act. Exhilaration from passage of these two foundational state laws was short-lived as the Golden State’s next governor, Republican George Deukmejian, slashed the new Coastal Commission’s budget in the early 1980s and afterward did all he could to dismantle the agency, headed by Michael L. Fischer. By then Douglas, en route to becoming the commission’s next executive director, guided it through the hard times.

Abstract Saturday Night Fever may have largely eluded the gender and sexual disorder of the 1970s, but it did so only by depicting its working-class characters as mired in a pre-1960s worldview. (Such strategic nostalgia was aided, no doubt, by the film’s adoption of many musical generic conventions.) But not every new nightlife film chose to avoid the 1960s. Richard Brooks’s Looking for Mr. Goodbar (1977) and William Friedkin’s Cruising (1980) both confronted contemporary gender and sexual relations more directly. In doing so, they seemed to indicate that this new social terrain could not be mapped using the old cinematic tools, whether those of the musical or romantic comedy—in large part because the terrain itself was so bewildering. Molly Haskell argued that the achievement of Goodbar came from its recognition of the “social nightmare” of heterosexual dating in the late 1970s, a world “in which there are no mutually understood signals, no rituals, no codes for deciphering the intentions of another individual.” Cruising, in turn, made visible another set of mixed social codes: the film’s persistent comparisons of gay S/M practices to law enforcement procedures (and vice versa) caused the New Yorker’s Roger Angell to be so unsure of the line dividing them that he wondered, “Are all cops, or most cops, gay?” Gender and sexual identity was being revised so quickly and so utterly in the late 1970s, it seems, that one needed a scorecard to keep all the players straight (as it were).

The lindenane sesquiterpenes, exemplified by chloranthalactone 4, display interesting physiological activity. Bo Liu of Sichuan University assembled (Organic Lett. 2011, 13, 5406) 4 by opening the epoxide 1 to the carbene, which cyclized to 3. Establishment of the relative configuration of sidechain stereogenic centers is a continuing issue in carbocyclic synthesis. Shigefumi Kuwahara of Tohoku University paired (Tetrahedron Lett. 2012, 53, 705) Sharpless epoxidation, to prepare 5, with the Stork epoxy nitrile cyclization, leading to (+)-rumphellaone A 7. Three competing structures had been put forward for the structure of (+)-lactiflorin 10. Thorsten Bach of the Technische Universität München settled (Angew. Chem. Int. Ed. 2012, 51, 1261) this controversy by preparing the most likely structure, 10, and showing that it was congruent with the natural product. A key step in the synthesis was the tethered 2+2 cycloaddition of 8 to give 9. The conversion of a carbohydrate to a carbocycle is a powerful strategy for the enantiospecific construction of natural products. En route to (–)-echinosporin 14, Karl J. Hale of Queen’s University Belfast added (Org. Lett. 2012, 14, 3024) the allene 12 to the enone 11, prepared from glucose, to give the cyclopentene 13. Richard J.K. Taylor of the University of York prepared (Tetrahedron Lett. 2010, 51, 6619) the enone 16 by oxidation of m-iodophenol 15 followed by asymmetric epoxidation. Reduction followed by deprotection and Pd-mediated coupling delivered (–)-harveynone 17. Some of the daphnane diterpene orthoesters, exemplified by (6,7-deoxy)-yuanhuapin 20, are single-digit nanomolar inhibitors of protein kinase C. Paul A. Wender of Stanford University, in the course of initial studies to optimize this remarkable activity, prepared (Nature Chem. 2011, 3, 615) 20 by way of the thermal cyclization of 18 to 19.

In the deep gravelly soils of the Bordeaux region, Seguin (1972) found vine roots at a depth of 6 m. Woody “framework roots” tend to be at least 30–35 cm be­low the surface and do not increase in number after the third year from planting (Richards 1983). Nevertheless, smaller diameter “extension roots” continue to grow horizontally and vertically from the main framework. They may extend lat­erally several meters from the trunk. These roots and finer lateral roots in the zone 10–60 cm deep provide the main absorbing surfaces for the vine. But in soils with a subsoil impediment to root growth, such as many of the duplex soils in south­east Australia (section 1.3.2.1), less than 5% of vine roots may penetrate below 60 cm (Pudney et al. 2001). Nor do vines root deeply in vineyards where irriga­tion supplies much of the vine’s water in summer. Plant roots and associated mycorrhizae (section 4.7.3.2) help to create soil structure. A desirable soil structure for vines provides optimal water and oxygen availability, which are fundamental for the growth of roots and soil organisms. The structure should be porous and not hard for roots to penetrate, allow ready exchange of gases and the flow of water, resist erosion, be workable over a range of soil water contents, allowing the seedlings of cover crops in vineyards to emerge, and be able to bear the weight of tractors and harvesting machinery with a min­imum of compaction. The quality of soil structure and its maintenance in vine­yards are discussed further in chapter 7. We might expect the soil particles described in chapter 2 simply to pack down, as happens in a heap of unconsolidated sand at a building site. However, if the sand is mixed with cement and water, and used with bricks, we can construct a building—a solid framework of floors, walls, and ceilings. This structure has in­ternal spaces of different sizes that permit all kinds of human activities. So it is with soil. Vital forces associated with the growth of plants, animals, and mi­croorganisms, and physical forces associated with the change in state of water and its movement act on loose soil particles.

Heat affected zone (HAZ) along with the weld seam of LSAW has discrete microstructure and usually shows lower toughness than base material. Grain coarsening and formation of M-A constituents governs the HAZ toughness, and a lot of efforts have been made to improve HAZ toughness. However, it is impossible to completely reduce the effect of microstructural change by seam welding. Especially, higher strength or heavy wall linepipes which have richer chemistry tend to have lower HAZ toughness. Therefore, it is important to understand the relationship between microstructural characteristics and toughness of HAZ and fracture behavior of HAZ region in order to ensure the structural reliability of seam welded region. In this paper, fracture behavior of X70 grade heavy wall UOE linepipe was investigated. Wide plate tensile test was conducted with the surface notch introduced on to the coarse grain HAZ, as well as the small scale testing such as Charpy and CTOD test. Fracture mechanics analysis was also carried out to understand the critical condition for brittle fracture of HAZ, and compared with the experimental results.

This paper describes actual experience applying a technology to achieve volume reduction while producing a stable waste form for low and intermediate level liquid (L/ILW) wastes, and the L/ILW fraction produced from pre-processing of high level wastes. The chief process addressed will be vitrification. The joule-heated ceramic melter vitrification process has been used successfully on a number of waste streams produced by the U.S. Department of Energy (DOE). This paper will address lessons learned in achieving dramatic improvements in process throughput, based on actual pilot and full-scale waste processing experience. Since 1991, Duratek, Inc., and its long-term research partner, the Vitreous State Laboratory of The Catholic University of America, have worked to continuously improve joule heated ceramic melter vitrification technology in support of waste stabilization and disposition in the United States. From 1993 to 1998, under contact to the DOE, the team designed, built, and operated a joule-heated melter (the DuraMelterTM) to process liquid mixed (hazardous/low activity) waste material at the Savannah River Site (SRS) in South Carolina. This melter produced 1,000,000 kilograms of vitrified waste, achieving a volume reduction of approximately 70 percent and ultimately producing a waste form that the U.S. Environmental Protection Agency (EPA) delisted for its hazardous classification. The team built upon its SRS M Area experience to produce state-of-the-art melter technology that will be used at the DOE’s Hanford site in Richland, Washington. Since 1998, the DuraMelterTM has been the reference vitrification technology for processing both the high level waste (HLW) and low activity waste (LAW) fractions of liquid HLW waste from the U.S. DOE’s Hanford site. Process innovations have doubled the throughput and enhanced the ability to handle problem constituents in LAW. This paper provides lessons learned from the operation and testing of two facilities that provide the technology for a vitrification system that will be used in the stabilization of the low level fraction of Hanford’s high level tank wastes.

This study investigates the autoignition of a Jet-A fuel spray in a preheated air flow in a 75mm inner diameter quartz tube at atmospheric pressure. Fuel was injected via a pressure-swirl atomizing injector enclosed in an aerodynamically-shaped outer body (7mm diameter) that is installed coaxially with the flow using 3 water-cooled pylons. The air temperature and oxygen content were in the range of 1000–1400 K and 9–12%, respectively by controlling the equivalence ratio in the primary zone of the pre-burner/vitiator and by adding dilution air downstream. The co-flow air velocity ranged from 25–30 m/s for this study (Re = 10,000–12,000), with a trapezoidal profile. Fuel spray was characterized using PDPA. Shape of the spray was transitional between hollow and solid cone with the corner angle of 35° to the axis near injector which reduced to 22° downstream. Spray density varied significantly over cross-section of the tube with the minimum on the axes. Droplets produced have average diameters (D10) of 15–70μm on the axes and periphery, respectively, at 6 cm downstream from the injector. Character of the droplet size distribution was polydisperse. Auto-ignition time delays were captured using a time-averaged camera with CH* (432nm) filter. The measured values agree with delay times previously reported in literature. Two synchronized high-speed cameras with 432nm and 307nm filters were used to investigate dynamics of auto-ignition kernel initiation and convection by capturing of CH* and OH* chemiluminescence at 5000 f ps. This methodology allowed qualitative characterization of the equivalence ratio of kernels in process of their convection and growth. It was shown that kernels are always initiated on the axes of the spray where the average droplet size is minimum. Kernels were formed leaner and become richer as they grow down-stream as indicated by the increase of CH*/OH*intensity ratio. Additionally, kernel behavior depends greatly on air temperature with kernels transitioning from randomly appearing (i.e. single kernel), to periodic, to a constantly auto-igniting flame with the spatial scatter of ignition kernels decreasing with temperature.

The control of propagating ductile (or tearing) fracture is a fundamental requirement in the fracture control design of pipelines. The Battelle two-curve method developed in the early 1970s still forms the basis of the analytical framework used throughout the industry. GASDECOM is typically used for calculating decompression speed, and idealizes the decompression process as isentropic and one-dimensional, taking no account of frictional effects. While this approximation appears not to have been a major issue for large-diameter pipes and for moderate pressures (up to 12 MPa), there have been several recent full-scale burst tests at higher pressures and smaller diameters for which the measured decompression velocity has deviated progressively from the predicted values, in general towards lower velocities. The present research was focused on determining whether pipe diameter was a major factor that could limit the applicability of frictionless models such as GASDECOM. Since potential diameter effects are primarily related to wall friction, which in turn is related to the ratio of surface roughness to diameter, an experimental approach was developed based on keeping the diameter constant, at a sufficiently small value to allow for an economical experimental arrangement, and varying the internal roughness. A series of tests covering a range of nominal initial pressures from 10 to 21 MPa, and involving a very lean gas and three progressively richer compositions, were conducted using two specialized high pressure shock tubes (42 m long, I.D. = 38.1 mm). The first is honed to an extremely smooth surface finish, in order to minimize frictional effects and better simulate the behaviour of larger-diameter pipelines, while the second has a higher internal surface roughness. The results show that decompression wave speeds in the rough tube are consistently slower than those in the smooth tube under the same conditions of mixture composition and initial pressure & temperature. Preliminary analysis based on perturbation theory and the fundamental momentum equation indicates that the primary reason for the slower decompression wave speed in the rough tube is the higher spatial gradient of pressure pertaining to the decompression wave dynamics, particularly at lower pressure ratios and higher gas velocities. The magnitude of the effect of the slower decompression speed on arrest toughness was then evaluated by a comparison involving several hypothetical pipeline designs, and was found to be potentially significant for pipe sizes DN450 and smaller.
