Summary Objectives: Today’s socio-economic developments in the healthcare area require continued optimization of processes and cost structures at hospitals, often associated with process changes for different occupational groups in the hospital. Formal methods for managing change have been established in other industries. The goal of this study was to assess the applicability of Kurt Lewin’s change management method to a health informatics-related project at a German university hospital. Methods: A project at the University Hospital Erlangen introducing changed requirements in the documentation of costly material in the surgical area was conducted following the concept of Lewin’s approach based on field theory, group dynamics, action research and the three steps of change. A data warehouse contributed information to several steps in the change process. Results: The model was successfully applied to the change project. Socio-dynamic forces relevant to the project goals were identified and considered in the design of the new documentation concept. The achieved documentation level met the new requirements and in some areas even exceeded them. Conclusions: Based on the project experiences, we consider Kurt Lewin’s approach applicable to change management projects in the hospital sector without a requirement for substantial additional resources, however, specific hospital characteristics need to be taken into account. The data warehouse played an important role by providing essential contributions throughout the entire change process.

This study examined change management and organizational performance in manufacturing companies in Anambra state, Nigeria. Relevant conceptual, theoretical and empirical literatures were reviewed. This study was anchored on organizational change and Lewin`s Three Step Model . Descriptive survey design was adopted, and primary data was employed. The population for the study was 286 employees working at the selected manufacturing companies in Anambra State. The entire population was used as the sample size for this study.The major instrument used for data collection was the questionnaire. Content Validity was adopted, and the test-retest method was used to test reliability of the research instrument. The study found that technological changes have a positive significant effect on organizational performance in manufacturing companies. Change management strategies have a positive significant effect on organizational performance in manufacturing companies in Anambra state. Leadership changes have a positive significant influence on organizational performance in manufacturing companies in Anambra state. The study concluded that change management has a positive significant effect on organizational performance in manufacturing companies in Anambra state. The study recommends that technology change had influenced employee performance since it simplifies the work to be done,thereby making work more efficient. Organizations which implement new technology should provide proper training to their employees to increase their performance. Every organization should build strong organizational management strategies that help to build good relationships based on their values, norms, behaviours, and perceptions.Leadership changes leaders’ mind-set, style, and behavior.The change process they design as a result of their orientation must encourage employees to want to participate, to choose to contribute, rather than force them to do so.

Context Change management is a discipline guiding how organizations prepare, equip, and support people to adopt a change to drive organizational success and outcomes successfully. Objective To introduce the concept of change management and create a primer document for athletic training educators to use in the classroom. Background While Lean and Six Sigma methodologies are essential for achieving a high-reliability organization, human resistance to change is inevitable. Change management provides a structured approach via different theoretical methods, specific principles, and tools to guide organizations through growth and development and serves an essential role during process improvement initiatives. Synthesis There are several theories or models of change management, 3 of which are specifically relevant in health care. Kotter and Rathgeber believe change has both an emotional and situational component and use an 8-step approach: increase urgency, guide teams, have the right vision, communicate for buy-in, enable action, create short-term wins, and make-it-stick [Kotter J., Rathgeber H. Our Iceberg is Melting: Changing and Succeeding Under Any Circumstances. New York, NY: St. Martin's Press, 2006]. Bridges' Transitional Model focuses on the premise that change does not influence project success; instead, a transition does [Bridges W. Managing Transitions: Making the Most of Change. Reading, MA: Addison-Wesley Publishing, 1991]. Lewin's model suggests that restraining forces influence organizations and that driving forces cause change to happen [Lewin K. Problems of research in social psychology. In: Cartwright D, ed. Field Theory in Social Science: Selected Theoretical Papers. New York, NY: Harpers; 1951]. Recommendation(s) Whether athletic trainers approach change management in a leadership role or as a stakeholder, newly transitioning professionals and those seeking leadership roles should value and appreciate change management theories and tools. Moreover, while no best practice statement exists relative to the incorporation of change management into a curriculum, addressing the subject early may allow immersive-experience students an opportunity to use change management during a process improvement initiative, facilitating a greater appreciation of the content. Conclusion(s) Athletic training curriculums should consider including change management course content, whether separately or in combination with other process-improvement content, thereby familiarizing athletic trainers with a common language for organizational and professional change.

Subject area The subject areas are organizational management, organizational behaviour and human resource management. Study level/applicability The study is applicable for courses in human resource management and organizational behaviour as part of masters-level programmes in business administration and management, executive development programmes on organization design and development for middle/senior management. Case overview In 2003, Elizabeth and Sunil Mehta had founded a voluntary organization, “Muktangan”, focussed on child-centric education through innovative pedagogy for the community of the urban poor. Elizabeth, an educationist, and Sunil, a highly successful business person, joined hands to contribute to the well-being of urban poor to make a difference to their lives. Elizabeth and Sunil presented a proposal to impart education for “the children of the community, by the teachers drawn from the community” to the residents of the slums in central Mumbai. With a humble beginning of running a small pre-school, Muktangan now manages seven schools with 3,400 children and 500 teachers, and a teachers’ training centre with a capacity to train 100 teachers a year. Muktangan won acclaim for its unique pedagogy and a very effective child-to-teacher ratio. Over the years, Elizabeth and Sunil led Muktangan with a strong passion and a “hands-on” approach. Of late, Elizabeth and Sunil faced questions from their donors about the sustainability of Muktangan with respect to leadership and management succession. Elizabeth and Sunil had a vision for Muktangan for self-directed growth with an empowered team. Muktangan embarked on the journey to create a leadership for self-directed growth. Sunil, Elizabeth and team Muktangan conceptualized and implemented a change management intervention with help from an external consultant to build the desired organization. Expected learning outcomes Outcomes are understanding issues involved in the leadership, organization design and management of change, particularly of those organizations engaged in social change and development in developing societies.

Fluorescence characteristics of the diatom Cylindrotheca closterium previously adapted to light intensities of 17, 200, and 800 μE·m−2·s−1 were investigated. Possibility of using fluorescence parameters for express score of both the algae functional state and the identification of a range of optimal light intensities for their growth was shown. The variable fluorescence coefficient (Fv/Fm) allows to evaluate in express mode the algae functional state in intensive cultivation conditions. It was shown that the maximum of Fv/Fm was of 0.65–0.7 for algae grown at light intensities of 17 and 200 μE·m−2·s−1; it decreased to 0.48–0.57 for algae adapted to light intensities of 800 μE·m−2·s−1. Light response curves of the electron transport rate, photochemical and non-photochemical quenching of chlorophyll fluorescence, and the Fv’/Fm’ coefficient values were obtained. These parameters indicate the degree of algae resistance to the light factor level. It was shown that saturating light intensity of about 200 μE·m−2·s−1 is optimal for the growth of C. closterium. The high values of yield of fluorescence per chlorophyll unit under extreme light intensity (800 μE·m−2·s−1) may indicate the degree of inactivation of part of photosystem II reaction centers.

The main objective of the study was to analyze the virtual mode tutorial activities of students of E- learning Management and Virtual Teaching in the School of Education, Unit of Second Major (Specialization), at Universidad National Pedro Ruiz Gallo, Perú. Kurt Lewin´s theory of group communication was assumed as a basis, and elements proposed by Aristotle, as the arguer, the topic and the listener, identified as the student, the teacher, the contents. A Tutorial plan was then designed, on the basis of the application of webinar as a technological support and with emphasis on an empathic counselling to get connection with the students and achieve the learning objectives in curricular experiences. Key words: tutorial, webinar, technology, counselling.

AbstractThis paper introduces an equation for determining instantaneous and final velocity of a sprinter in a 100 m run completed with a wind resistance ranging from 0.1 to 4.5 m/s. The validity of the equation was verified using the data of three world class sprinters: Carl Lewis, Maurice Green, and Usain Bolt. For the given constant wind velocity with the values + 0.9 and + 1.1 m/s, the wind contribution to the change of sprinter velocity was the same for the maximum as well as for the final velocity. This study assessed how the effect of the wind velocity influenced the change of sprinting velocity. The analysis led to the conclusion that the official limit of safely neglecting the wind influence could be chosen as 1 m/s instead of 2 m/s, if the velocity were presented using three, instead of two decimal digits. This implies that wind velocity should be rounded off to two decimal places instead of the present practice of one decimal place. In particular, the results indicated that the influence of wind on the change of sprinting velocity in the range of up to 2 m/s and was of order of magnitude of 10-3 m/s. This proves that the IAAF Competition Rules correctly neglect the influence of the wind with regard to such velocities. However, for the wind velocity over 2 m/s, the wind influence is of order 10-2 m/s and cannot be neglected.

Abstract A significant change in properties of the thermocline is observed across the whole Indian Ocean 32°S section between 1987 and 2002. This change represents a reversal of the pre-1987 freshening and decreasing oxygen concentrations of the upper thermocline that had been interpreted as a fingerprint of anthropogenic climate change. The thermocline at the western end of the section (40°–70°E) is occupied by a single variety of mode water with a potential temperature of around 13°C. The thermocline at the eastern end of the 32°S section is occupied by mode waters with a range of properties cooling from ∼11°C at 80°E to ∼9°C near the Australian coast. The change in θ–S properties between 1987 and 2002 is zonally coherent east of 80°E, with a maximum change on isopycnals at 11.6°C. Ages derived from helium–tritium data imply that the mode waters at all longitudes take about the same time to reach 32°S from their respective ventilation sites. Dissolved oxygen concentration changes imply that all of the mode water reached the section ∼20% faster in 2002 than in 1987.

It has been found recently that the dynamic behavior of a cavitating hydrofoil is different from that in pure water in that, not only are the natural frequencies different, but the mode shapes may also change. In order to elucidate the mechanism behind this phenomenon, finite element simulations were carried out based on acoustic–structure coupling equations. It was found that the structure and acoustic modes exhibit mode transitions with the variation of the sound speed in the cavity. Further, the mode transition was caused by coupling of the structure with the acoustic modes, which was induced by the vapor mode. The amplitude of the vibration near the mode transition point was high and the mode shape was easily excited. Moreover, with the change of the sound speed in the cavity, the different distributions of the acoustic pressure mode resulted in different structure mode shapes, even on the same transition line. Considering this, a sheet cavitation was simulated by a small change of the void fraction to 0.999 and the sound speed from 343 to 275 m/s to obtain good agreement with the experimental data. Both results showed that the second bending mode under cavitation conditions became a bending–torsion coupled mode.

Lewis remained a figure of significance in the decades after his death despite dramatic social change in the second half of the twentieth century. The reasons for this continued visibility involve circumstances particular to Lewis and larger social changes, especially in communications and media technologies, education, and culture. Innovation in communications media—radio, the paperback, television, and film—meant that incrementally greater numbers of people became familiar with the name of C. S. Lewis. Dramatic expansions in education also contributed to the canonization of his books. This period also saw a bifurcation in Lewis’s platform between the more commercially successful author of the Narnia books and the Christian apologist intensely admired in America. Lewis’s enduring visibility is to be credited to a myriad of circumstances particular to him and to the profound social changes affecting the religious, cultural, and intellectual life of twentieth-century Britain and America.

After summarizing the book’ s alternative recursive analysis of the Athenian politeia, the chapter confronts three possible objections to this new account. First, despite possible appearances to the contrary, this kind of ontological history can in fact accommodate the “messiness” of “real life.” While its primary purpose is to recover the ontological and metaphysical commitments which were presupposed by Athenian demokratia, it is not necessarily contradicted by evidence for conduct that might seem to defy those commitments. Second, nor is this kind of analysis necessarily contradicted by the texts of, say, Plato, Thucydides, or other contemporary intellectuals which seem to offer us very different accounts of Greek “realities.” Such texts represent the thought of only a tiny elite minority, intellectuals who were expressly challenging conventional presuppositions about the givens of existence. And it is those conventional presuppositions which the book is primarily concerned with, since they constituted the “world-making common sense” of the age, the social knowledge that was at once presupposed and reproduced by the most vital life-sustaining practices of the Athenians, the thought which actively helped to make their world whatever it really was at the time. By contrast, elite oppositional claims were merely ideational constructs, mere renegade “worldviews.” Third, while the book’ s ontological history is written in the synchronic mode, treating the classical era as a single extended moment, this does not mean that it is incapable of accounting for change. Indeed, as the chapter shows, it is quite possible to imagine a diachronic ontological history.

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.

In The Chronicles, Lewis comes as close to mysticism as he has in any other book, for Aslan, the holy of holies is the numinous made present. Though his apologetic writing becomes less polemical, a public not-avowedly Christian Lewis remains militant. Lewis has undergone many changes: near-despair, forgiveness, marriage, a monumental professional move, and a steady, but very new, rhythm that was less urgent. ‘A new day’ describes his one real novel, Till We Have Faces (1956), and other works: ‘Meditation in a Toolshed’, ‘Membership’, ‘The Seeing Eye’, Reflections on the Psalms, and The Four Loves. After the death of Joy in 1960, Lewis published A Grief Observed under the pseudonym N. W. Clerk.

This chapter argues that the EU’s response(s) to the Arab Spring can be best described as hybrid and is (are) closely reflective of the very hybridity of the EU’s international identity. On the one hand, despite genuine normative impetuses, a largely realist approach and exclusive identities and roles prevailed in crisis management and short-term reactions driven by intergovernmental decision-making. The EU’s crisis management responses are examined in the cases of three different groups of Arab countries – those having witnessed regime change, civil conflict and regime resilience. On the other hand, a more liberal outlook and inclusive identities and roles were embodied in strategic or long-term responses in the framework of the European Neighbourhood Policy, although the latter’s inherent contradictions and lack of innovation in relation to past policies eventually deprived them of the value-based and progressive effect envisaged on paper. Finally, the EU returned to crisis mode in managing the Syrian refugee inflow that was framed as a ‘crisis’ and took the ‘fortress Europe’ identity to its utmost degree from 2015 onwards.

We are living in a historical moment that will be known for its emphasis on media engagement. The evolution of mobile media technology, the ubiquity of social media, and the omnipresence of multiple media platforms in each of our lives have led to new and evolving modes of interaction with the experience of the media screen. The interactive conditions of digital culture in the United States align with a significant historical moment: growing political and social upheaval, economic crisis, dissatisfaction with representative government, and disillusionment with state institutions. Together, these conditions have given rise to an emerging participatory media culture(s) engaged in addressing problems, exposing exploitation, facilitating media witnessing, and taking back the means of media production and circulation. The chapter argues for an understanding of documentary practice as a mediated commons. This book focuses on how the visual culture(s) of documentary moving images are harnessed as a means of resistance in forms that include witnessing, petition, solidification, polarization, and promulgation. It will examine the ways in which documentary as a mode of production engages in the process of social change.

The phonon dissipation is investigated through molecular dynamics (MD) simulation modeling graphene flake sliding on supported graphene in this paper. With the help of the advantage of MD, we explore the phonon mode variation of the substrate induced by the behavior of friction in terms of phonon densities of states. Moreover, phonon dissipation modes connected with the relative sliding velocity and the temperature of system are established respectively. The simulation results demonstrate phonon dissipation is represented as special phonon frequencies while those are closely related to the sliding velocities but would not shift as the change of temperatures. For an explanation of the special frequencies, we further simplify the model by directly adding the velocity to the atoms of the flake in the MD model, although it is impractical. It is found that a special frequency of phonon dissipation is generally in agreement with the sliding frequency at low temperature eliminating the interference of temperature in a range of velocities from 50m/s to 250m/s, namely, the velocity is directly related to the modes of phonon dissipation and friction, which is consistent with the previously reported result[1] that the velocity is an influence factor for friction both in experimental and theoretical researches. Therefore, the relationship makes possible the active control of friction. It is the first step toward using this method to reveal the fundamental questions in the study of atomic-scale friction.

Abstract Low power mode current is a very important parameter of most microcontrollers. A non-production prototype microcontroller had high current issues with certain SRAM modules which were produced using a new memory compiler. All devices were measuring 100’s μA of low power mode current which was an order of magnitude higher than the requirement. Many failure analysis (FA) techniques had to be used to determine the root cause: Optical Beam Induced Resistance Change (OBIRCh), photo emission microscopy (PEM), microprobing, and nanoprobe device characterization. Transistor models and measurements of probe structures from the effected lots both predicted that the device low power mode current would meet expectations; however, all first silicon samples had elevated low power mode current. A knowledge of low power design methodology was needed to ensure all issues were discovered.

Tribochemical interactions between antiwear zinc dithiophosphate (Zndtp), friction modifier molybdenum dithiocarbamate (Modtc) and overbased detergent calcium borate (OCB) lubricant additives have been investigated. A Cameron-Plint friction machine was used to generate large tribofilm areas in mild tribological conditions. Two analytical techniques, X-ray photoelectron spectroscopy (XPS) and X-ray absorption near edge structure spectroscopy (XANES), have been employed to characterize the chemical species in tribofilms. XANES spectroscopy at the P K and L-edges, S K-edge, Mo L and M-edges and B K-edge was carried out in order to investigate phosphate, sulfide and borate species in tribofilms. The XANES spectra were recorded in both the total electron yield (TEY), surface sensitive and fluorescent yield (FY), bulk sensitive mode. This was completed with XPS analyses in the same location in the tribofilm. The ternary system Zndtp + Modtc + OCB provides a low wear rate comparable to the binary system Modtc + OCB. XANES analyses have shown that adding OCB to the binary system Zndtp + Modtc increases the formation of MoS2 and reduce the formation of ZnS. It has been seen that few quantity of boron is consumed during the tests, meaning that boron does not react with other additives, we only observe a formation of calcium phosphate. A special attention has been paid on the hybridization of boron (trigonal sp2 and tetrahedral sp3). All tribofilms show a higher proportion of trigonal borate than the additives alone. However, this proportion is the highest in the case of tribofilms produce with the ternary mixture OCB + Zndtp + Modtc. Borate has a planar conformation and could be friction-oriented in the sliding interface. The oriented borate planar molecule might be at the origin of the MoS2 sheets orientation in the ternary system.

This paper deals with the non-singular assembly mode changing of a six degrees of freedom parallel manipulator. The manipulator is composed of three identical limbs and one moving platform. Each limb is composed of three prismatic joints of directions orthogonal to each other and one spherical joint. The first two prismatic joints of each limb are actuated. The planes normal to the directions of the first two prismatic joints of each limb are orthogonal to each other. It appears that the parallel singularities of the manipulator depend only on the orientation of its moving platform. Moreover, the manipulator turns to have two aspects, namely, two maximal singularity free domains without any singular configuration, in its orientation workspace. As the manipulator can get up to eight solutions to its direct kinematic model, several assembly modes can be connected by non-singular trajectories. It is noteworthy that the images of those trajectories in the joint space of the manipulator encircle one or several cusp point(s). This property can be depicted in a three dimensional space because the singularities depend only on the orientation of the moving-platform and the mapping between the orientation parameters of the manipulator and three joint variables can be obtained with a simple change of variables. Finally to the best of the authors’ knowledge, this is the first spatial parallel manipulator for which non-singular assembly mode changing trajectories have been found and shown.

The presence of hemostatic abnormalities has been reported in decompression sickness. It is suggested that platelets recognize air bubbles in the blood stream as a foreign surface and adhere to them with ensuing platelet aggregation. It is important to determine if consumption of platelets occurs in vivo to understand a role of platelets in the genesis of decompression sickness. To analyse the problem, platelet behavior was studied in 34 rabbits with decompression sickness which was brought about by the exposure to 6 ATA (atmospheres absolute) for 40 min followed by rapid decompression. All rabbits died within one hr after the decompression due to apnea which always preceded the cardiac arrest. Platelet counts decreased significantly during the time course of decompression. A regression line can be drawn between the changes in platelet count (Y) and the time after decompression (X): Y=100.2 - 0.8X, r= -0.876, p<0.001. Platelet counts measured just before the apnea were 56 to 72% (65.7 ± 6.1%) of the precompression value. Kinetic studies with 111 In-oxine-labeled platelets revealed shortened survivals of the circulating platelets and autoradiograms indicated the accumulation of radioactivity in the lungs after the decompression. Although there was no change in the mode volume of platelets after the decompression, the transient appearance of smaller or fragmented platelets suggested a random over-destruction of platelets. Whole and releasable adenine nucleotide contents of platelets decreased significantly after the decompression. There were no significant changes in cytoplasmic adenine nucleotide contents. Therefore, in decompression sickness, the circulating platelets behaved similarly to those of acquired storage pool disease. Platelet thrombi were found in the pulmonary artery, compatible with the accumulation of the labeled platelets. These findings suggest that circulating air-bubbles interact with circulating platelets, causing the platelet release reaction, and these activated platelets participate in the formation of thrombi in decompression sickness.

Abstract Drilling challenging wells requires a combination of drilling analytics and comprehensive simulation to prevent poor drilling performance and avoid drilling issues for the upcoming drilling campaign. This work focuses on the capabilities of a drilling simulator that can simulate the directional drilling process with the use of actual field data for the training of students and professionals. This paper presents the results of simulating both rotating and sliding modes and successfully matching the rate of penetration and the trajectory of an S-type well. Monitored drilling data from the well were used to simulate the drilling process. These included weight on bit, revolutions per minute, flow rate, bit type, inclination and drilling fluid properties. The well was an S-type well with maximum inclination of 16 degrees. There were continuous variations from rotating to sliding mode, and the challenge was approached by classifying drilling data into intervals of 20 feet to obtain an appropriate resolution and efficient simulation. The simulator requires formation strength, pore and fracture pressures, and details of well lithology, thus simulating the actual drilling environment. The uniaxial compressive strength of the rock layer is calculated from p–wave velocity data from an offset field. Rock drillability is finally estimated as a function of the rock properties of the drilled layer, bit type and the values of the drilling parameters. It is then converted to rate of penetration and matched to actual data. Changes in the drilling parameters were followed as per the field data. The simulator reproduces the drilling process in real-time and allows the driller to make instantaneous changes to all drilling parameters. The simulator provides the rate of penetration, torque, standpipe pressure, and trajectory as output. This enables the user to have on-the-fly interference with the drilling process and allows him/her to modify any of the important drilling parameters. Thus, the user can determine the effect of such changes on the effectiveness of drilling, which can lead to effective drilling optimization. Certain intervals were investigated independently to give a more detailed analysis of the simulation outcome. Additional drilling data such as hook load and standpipe pressure were analyzed to determine and evaluate the drilling performance of a particular interval and to consider them in the optimization process. The resulting rate of penetration and well trajectory simulation results show an excellent match with field data. The simulation illustrates the continuous change between rotating and sliding mode as well as the accurate synchronous matching of the rate of penetration and trajectory. The results prove that the simulator is an excellent tool for students and professionals to simulate the drilling process prior to actual drilling of the next inclined well.

Abstract A full scale experimental beam expander structure is modeled and correlated with modal test results on a component and system level. Correlation of the FE models is completed using the LINK module of the Leuven Measurement Systems (LMS) software which is also used to acquire and reduce the modal test data. The correlation tools used to measure the agreement between test and analytic mode shapes are the Modal Assurance Criterion (MAC), Coordinate Modal Assurance Criterion (CoMAC), and mass cross-orthogonality. In addition to the tools used to measure agreement between test and analysis modal parameters, sensitivity and optimization algorithms are used to identity structural parameters which influence a particular mode and what the minimum change(s) must be in the parameter(s) to bring about the desired agreement. As part of a system level pre-test analysis, the theoretical mode shapes along with a normalized line-of-sight error associated with each mode are used to select the best measurement and excitation locations.

An investigation was conducted to understand flow boiling of de-ionized water in locally heated parallel microchannels. High speed visualization technology was employed to visually observe the transient phase change process in an individual microchannel. The process at locally heated condition was different from those at entirely heated condition where vapor column(s) stayed quasi-stable for a long time without venting out. Intensive interface oscillation occurred during phase change. Thin film evaporation appeared to be the main evaporation mode at the upstream vapor column cap, whereas nucleation happened occasionally at favorable flow, heat transfer and local wall conditions. Continuous condensation at the downstream vapor column cap led the flow back to single liquid phase regime out of the microchannel. A signal analysis method was introduced to study the interfacial oscillation behavior at the evaporating cap, which showed marked impact of the evaporation mode on the characteristic frequency.
