Academic literature on the topic 'General two-stage model'

The history of the study of snails in the genus Cepaea is briefly outlined. Cepaea nemoralis and C. hortensis are polymorphic for genetically controlled shell colour and banding, which has been the main interest of the work covered. Random drift, selective predation and climatic selection, both at a macro– and micro–scale, all affect gene frequency. The usual approach to understanding maintenance of the polymorphism, has been to look for centripetal effects on frequency. Possible processes include balance of mutation pressure and drift, heterozygote advantage, relational balance heterosis, frequency–dependent predation, multi–niche selective balance, or some combination of these. Mutational balance is overlaid by more substantial forces. There is some evidence for heterosis. Predation by birds may protect the polymorphism, and act apostatically to favour distinct morphs. Although not substantiated for Cepaea , many studies show that predators behave in the appropriate manner, while shell colour polymorphisms in molluscs occur most commonly in species exposed to visually searching predators. It is not known whether different thermal properties of the shells help to generate equilibria. Migration between colonies is probably greater than originally thought. The present geographical range has been occupied for less than 5000 generations. Climatic and human modification alter snail habitats relatively rapidly, which in turn changes selection pressures. A simple simulation shows that migration coupled with selection which fluctuates but is not centripetal, may retain polymorphism for sufficiently long to account for the patterns we see today. There may therefore be a two–stage basis to the polymorphism, comprising long–term but weak balancing forces coupled with fluctuating selection which does not necessarily balance but results in very slow elimination. Persistence of genetic variants in this way may provide the conditions for evolution of a balanced genome.

With the wind farm data from the southeast coast this paper builds a two-stage combination forecasting model of output power based on data preprocessing which include filling up missing data and pre-decomposition. The first stage is a composite prediction of decomposed power sequence in which a time series and optimized BP neural network predict the general trend and the correlation of various factors respectively. The second stage is BP neural network with its input is the results of first stage. The effectiveness and accuracy of the two-stage combination model are verified by comparing the mean square error of the combination model and other models.

This thesis consists of two main elements: the analysis of field measurements of velocity and resistance in a river, undertaken over a three year period, and numerical modelling of open channel flow. An Acoustic Doppler Current Profiler (ADCP) was used to measure the spatial distribution of velocity in two cross sections of a small meandering river (River Blackwater, Hampshire) during inbank, bankfull and overbank flow conditions. The same reach of the river had been previously studied over a number of years, as well as investigated on a 1:5 scale physical model, making it possible to compare the flow structure in the river and in the physical model. A new measurement procedure and data processing methodology were developed for ADCP measurements, suitable for use in times of flood. Methods for orientating the measured velocity data and reducing the velocity fluctuations in the data, due to their instantaneous random nature, are described. The post processed data has been verified against 300s time-averaged velocity data at several locations along the cross sections, and also against ADV measurements obtained under the same flow conditions. The approach of averaging several transect data together has successfully reduced the noise in the ADCP velocity data. The field data indicates incremental rises in Ud with rising water level, while the opposite is true for the physical model data. Key similarities and differences between the secondary flow patterns in the river and model have been identified. The discharge capacity of the main river channel is significantly reduced during summer months, due to seasonal growth in vegetation, reaching a minimum in August. The gradient of the stagedischarge rating curve for summer months can be seven times larger than that for the winter months. The falling limbs of the rating curve have a higher discharge capacity than the rising limbs for summer months (June/July to October/November). An attempt was made to predict the stagedischarge relationship for overbank flow conditions using a quasi 2D RANS model, SKM (Shiono and Knight Method). SKM is shown to be capable of simulating the lateral distribution of the depthaveraged streamwise velocity in the river and physical model with reasonable accuracy, subject to appropriate choice of three calibration parameters. The research shows that the ADCP has a great potential for obtaining accurate 3D velocity data in rivers during flood events, and that the SKM is a useful modelling tool. The importance of taking into account the effect of vegetation when undertaking engineering design has been demonstrated.

Real-world large-scale complex networks such as the Internet, social networks and biological networks have increasingly attracted the interest of researchers from many areas. Accurate modelling of the statistical regularities of these large-scale networks is critical to understand their global evolving structures and local dynamical patterns. Traditionally, the Erdos and Renyi random graph model has helped the investigation of various homogeneous networks. During the past decade, a special computational methodology has emerged to study complex networks, the outcome of which is identified by two models: the Watts and Strogatz small-world model and the Barabasi-Albert scale-free model. At the core of the complex network modelling process is the extraction of characteristics of real-world networks. I have developed computer simulation algorithms for study of the properties of current theoretical models as well as for the measurement of two real-world complex networks, which lead to the isolation of three complex network modelling essentials. The main contribution of the thesis is the introduction and study of a new General Two-Stage growth model (GTS Model), which aims to describe and analyze many common-featured real-world complex networks. The tools we use to create the model and later perform many measurements on it consist of computer simulations, numerical analysis and mathematical derivations. In particular, two major cases of this GTS model have been studied. One is named the U-P model, which employs a new functional form of the network growth rule: a linear combination of preferential attachment and uniform attachment. The degree distribution of the model is first studied by computer simulation, while the exact solution is also obtained analytically. Two other important properties of complex networks: the characteristic path length and the clustering coefficient are also extensively investigated, obtaining either analytically derived solutions or numerical results by computer simulations. Furthermore, I demonstrate that the hub-hub interaction behaves in effect as the link between a network's topology and resilience property. The other is called the Hybrid model, which incorporates two stages of growth and studies the transition behaviour between the Erdos and Renyi random graph model and the Barabasi-Albert scale-free model. The Hybrid model is measured by extensive numerical simulations focusing on its degree distribution, characteristic path length and clustering coefficient. Although either of the two cases serves as a new approach to modelling real-world large-scale complex networks, perhaps more importantly, the general two-stage model provides a new theoretical framework for complex network modelling, which can be extended in many ways besides the two studied in this thesis.

This study critically explores the link between internationalisation theories and outward foreign direct investment (FDI) – a linkage which is well documented in the literature. Numerous studies have established that the internationalisation process recognises both firm- and market-specific aspects, which greatly determine the direction of outward FDI in terms of volume and pattern. In this interaction, path dependency is determined by the intensity of overlapping aspects or linkages, from firm-level heterogeneity and host market aspects that direct investment patterns in terms of the latter, to the volumes of firm-level adjustments. Firm-level heterogeneity comprises those traits, which enable an individual firm to make an investment decision, select a market-entry strategy and create the competitive advantages that will sustain its investments. Macro-level or country-specific aspects encompass those traits or characteristics of host markets, which encourage FDI on the part of multinational enterprises (MNEs). Most studies overlook the path dependency of country- and firm-specific aspects, which are crucial to the internationalisation processes of international business, economics and trade. Academic studies either focus on macro- or micro-level aspects, without paying specific attention to the path dependency of expansion strategies. The present study attempts to fill these gaps in the existing body of knowledge, by investigating international business in these contexts. The rationale for undertaking this study was two-fold: first, FDI holds proven benefits for host markets, which include economic growth, industry spillover, human capital development and transitory tacit knowledge. From a firm-level perspective, outward FDI largely enhances the capacity of MNEs, prompting an increase in asset accumulation, market share and human capital development, the more efficient utilisation of resources and return on equity. In this study, an argument is presented for measuring the variables of both firm- and market-specific aspects, since most existing studies in this genre focus either on micro- or macro-level determinants, or totally overlook the importance of linkages. Second, no documented research has investigated the path dependency of expansion strategies, especially in Africa. Crucially, the importance of path dependency of South Africa’s outward investment has not been documented either. Further, existing evidence on the role the path dependency of expansion strategies plays in outward FDI are scarce, with even fewer studies following a sectorial approach. This study attempts to fill these academic research gaps by reflecting both firm- and market-level data from various sources for the period 1995–2015, using panel dynamic regression models. The study found that the linkages between firm heterogeneity (firm-level evidence) and market-level aspects create a path dependency of expansion strategies. MNEs adopt either joint ventures or wholly owned subsidiaries (or both) as market-entry strategies, but the decision is informed by the intensity of those firm heterogeneity aspects that allow them to exploit opportunities and mitigate risk in host markets. Notably, the intensity of path dependency seemingly varies from one industrial segment to the next. The impulse response approach delivered evidence that one standard deviation shock of firm-specific variables led to a moderate improvement in firm-level capacities in the short run, but a significant improvement in the long run. The same result was recorded for market-level aspects, with the intensity of the results varying from one industry to the next. The causality test attempted to explore the causal relationship between the study variables in both firm- and market-level aspects. Empirical evidence from the study indicates that the size of the firm and its capacity to utilise its resources efficiently, influence their investment in host markets. As regards market-specific aspects, the size of the economy, levels of industry and trade openness were found to have a causal effect on the inflow of FDI in host markets. The intensity of causal aspects was also found to vary from one industry to the next, due to variations in firm-level heterogeneity and their linkage in terms of aspects related to the host market. In sum, this study complements existing material on the subject of international business.

This chapter integrates three approaches to the question of why successful identities—individual and organizational—generally involve a balance between conformity to others’ practices and differentiation from them. An entertaining model is employed to highlight the limitations of the “optimal distinctiveness” and the “different audiences” approaches. A third approach—“two-stage valuation”—is then shown to address these limitations. It is also demonstrated that this approach provides a general foundation for understanding the balance between conformity and differentiation. The advantages of this framework are (a) parsimony, as it requires no unnecessary behavioral assumptions; (b) generality, as it applies at both the individual and organizational levels of analysis and is capable of incorporating the distinctive observations of the other two approaches; and (d) extensibility, as it is capable of illuminating outstanding puzzles, such as why closely resembling others may sometimes convey legitimacy but may sometimes be a problematic sign of inauthenticity.

This book examines the impact that Athenian Old Comedy had on Greek writers of the Imperial era. It is generally acknowledged that Imperial-era Greeks responded to Athenian Old Comedy in one of two ways: either as a treasure trove of Atticisms, or as a genre defined by and repudiated for its aggressive humor. Worthy of further consideration, however, is how both approaches, and particularly the latter one that relegated Old Comedy to the fringes of the literary canon, led authors to engage with the ironic and self-reflexive humor of Aristophanes, Eupolis, and Cratinus. Authors ranging from serious moralizers (Plutarch and Aelius Aristides) to comic writers in their own right (Lucian, Alciphron), to other figures not often associated with Old Comedy (Libanius) adopted aspects of the genre to negotiate power struggles, facilitate literary and sophistic rivalries, and provide a model for autobiographical writing. To varying degrees, these writers wove recognizable features of the genre (e.g., the parabasis, its agonistic language, the stage biographies of the individual poets) into their writings. The image of Old Comedy that emerges from this time is that of a genre in transition. It was, on the one hand, with the exception of Aristophanes’s extant plays, on the verge of being almost completely lost; on the other hand, its reputation and several of its most characteristic elements were being renegotiated and reinvented.

This collective monograph is a comprehensive study of the causes, evolution and outcomes of complex processes in the contemporary history of the countries of Central and South-Eastern Europe, and aims in particular to identify common and special characteristics in their socio-economic and political development. The authors base their work on documentary evidence; both published and unpublished archival materials reveal the specifics of the development of the political landscapes in these countries. They highlight models combining both European and nationally oriented (and even nationalist) components of the political spheres of particular countries; identify markers which allow the stage of completion (or incompletion) of the establishment of a new political system to be estimated; and present analyses of the processes of internal political struggle, which has often taken on ruthless forms. The analysis of regional and country-specific documentary materials illustrates that the gap in the development of the region with “old Europe” in general has not yet been overcome: in the post-Socialist period, the situation of the region being “ownerless” and “abandoned”, characteristic of the period between the two world wars, is reoccurring. The authors conclude that during the period from the late twentieth to the early twenty-first centuries, the region was quite clearly divided into two parts: Central (the Visegrad Four) and South-Eastern (the Balkans) Europe. The authors explore the prevailing trends in the political development of Hungary and Poland related to the leadership of nationally and religiously oriented parties; in the Czech Republic and Slovakia the pendulum-like change in power of the left and right-wing parties; and in Bulgaria and Romania the domestic political processes permanently in crisis. The authors pay special attention to the contradictory nature of the political evolution of the states that emerged in the space of the former Yugoslavia. For the first time, Greece and Turkey are included in the context of a regional-wide study. The contributors present optimal or resembling transformational models, which can serve as a prototype for shaping the political landscape of other countries in the world. The monograph substantiates the urgency of the new approach needed to study the history and current state of the region and its countries, taking into account the challenges of the time, which require strengthening national and state identity. The research also offered prognostic characteristics of transformational changes in the region, the Visegrad Four, and the Balkans.

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.

This chapter focuses on selected problems of complex systems identification. The first part of the chapter is devoted to identification problems in general. The tasks of determination of the plant parameters and choice of the best model are given. Then, authors describe problems of complex systems, i.e.: identification with use of limited measurements, global identification and two-stage identification. The last one is presented in details. In order to illustrate proposed methods, an adaptive system with two-stage identification and its application to biomedical problem is presented.

In so far as velar softening is a two-stage process involving velar palatalization and velar assibilation, it is claimed that these two sound-change mechanisms ought to be analysed separately. A distinction is made between front velar stop productions, and the (alveolo)palatal stop outcome of gestural blending between velar stops and front vocalic realizations. The chapter also presents and evaluates two general models of velar softening, i.e., the articulation-based model proposed by the Neogrammarians and the acoustic equivalence model proposed by Ohala and colleagues. Several arguments in support of the former model are presented, which are based on articulatory evidence and on experimental findings reported in earlier acoustico-perceptual studies.

Chapter 5 examines Plato’s account of the method of learning by paradeigma (‘model’) in the Statesman (277c7-283a9). It first explains what the method is and then considers the two parties who are described as using it: children who are learning to read and write and the dialogue’s two interlocutors. It highlights some parallels between each party’s use of the method. These parallels illuminate important features of dialectical inquiry in general and the Visitor and Young Socrates’ inquiry in particular, including the nature of the knowledge they ultimately hope to achieve, and one stage in the complex process by which they aim to achieve it.

Due to the popularity of 3D graphics in animation and games, usage of 3D geometry deformable models increases dramatically. Despite their growing importance, these models are difficult and time consuming to build. A distance learning system for the construction of these models could greatly facilitate students to learn and practice at different time and geographical locations. In such a system, an important component is the search engine, which serves as both the source of teaching materials and a platform for sharing resources. Although there have been a lot of works on text and multimedia retrieval, search engines for 3D models are still in its infant stage. In this article, we investigate two important issues: feature analysis, which affects the general usage of a system, and speed, which affects the number of concurrent users. Our method offers a mechanism to extract, index, match and efficiently retrieve features from these models.

Graphite intercalation compounds (GICs) have unique layered structures where intercalate layers are arranged periodically between graphite layers. This phenomenon is known as staging, and the number of graphite layers between adjacent intercalate layers is known as the stage number n. As the stage number n increases, the separation between adjacent intercalate layers becomes larger. So the interlayer interactions between intercalate layers become weak, leading to a crossover of dimensionality from three-dimensional (3D) to two-dimensional (2D). Because of their intrinsic anisotropy, GICs exhibit a great variety of structural orderings such as staging, in-plane ordering of intercalate layers, and stacking ordering of both graphite and intercalate layers. The stable stage and in-plane ordering of the intercalate layers depend on the relative strength of the intercalate-graphite interaction to the intercalate-intercalate interaction. At low temperatures the intercalate layers form a variety of 2D superlattices resulting from the competing interactions. At elevated temperatures the superlattice undergoes a transition to a 2D liquid. The migration of intercalate atoms is restricted to the 2D gallery between graphite layers. The critical temperature below which the stacking order appears is equal to or lower than the critical temperature below which the in-plane order appears. In this chapter, we review the subject of structures, phase transitions, and kinetics for donor and acceptor GICs. The subject matter of this chapter is organized as follows. Section 3.1 deals with the general structural characteristics of GICs. Sections 3.2 and 3.3 are respectively devoted to descriptions of liquid state and phase transitions of stage-2 alkali metal GICs. Section 3.4 deals with the discommensuration domain model for high-stage alkali metal GICs. Sections 3.5 and 3.6 are devoted to descriptions of liquid-solid transitions in stage-1 K and Rb GIC. In Sections 3.7-3.9, we describe the stage transition, Kirczenow’s model, Hendricks-Teller-type stage disorder, and fractional stage. In Sections 3.10 and 3.11 we describe the phase transitions of acceptor-type GICs (Br2 GIC and SbCl5 GIC). Section 3.12 treats the ordering kinetics in K GIC and SbCl5 GIC.

This chapter considers the use of modelling for public health economic evaluation. The approach to decision analytic modelling within health economic evaluation is described and five key challenges relating to modelling public health interventions are highlighted: incorporating equity; extrapolating multi-component intervention effectiveness beyond study data; capturing relevant complex relationships and feedback loops of a dynamically complex system; modelling human behaviour; and capturing relevant non-health costs and outcomes and the relationship between individual and social determinants. The chapter describes current practice and the latest methodological research in these areas. It outlines two general approaches which could help to address these challenges by (i) adopting an iterative approach to the evaluation by using early-stage decision modelling to guide primary data collection, and (ii) a conceptual modelling framework to guide the model development process.

Introduction. The article deals with the problem of students’ academic professional literacy development by means of a foreign language based on the implementation of the SIOP Model. The foundations of the question have been borrowed from the SIOP (Sheltered Instruction Observation Protocol) Model that focuses on helping English Language Learners (ELLs) with academics in a mainstream classroom. The SIOP Model provides a practical and flexible tool for educators to use in planning, implementing and observing Sheltered Instruction. The SIOP Model is one of the two major areas, the other being General English, which is established in the English-speaking world. The professionally oriented English course is developed for students from different non-linguistic specialties. The goals, objectives, content of the course are compiled according the students’ requirements of real target foreign language communication situations. The principles and approaches that underlie occupational mobility are outlined. It is revealed that occupational mobility serves as a criterion for evaluating the effectiveness of professional development. The aim of the study. The aim of this paper is to outline the improving the efficiency of foreign language teaching for future non-linguistic specialists with the iplementation of the SIOP Model. Methods of the research. Methods of the research include theoretical - study of literature, experience on the problem, theoretical analysis of philosophical, sociological, psychological, pedagogical literature on research topics, synthesis of theoretical and empirical material, its generalization and systematization of data, modeling, comparison, forecasting; as well as a set of empirical methods – observations, study and generalization of pedagogical experience. Results. . It is revealed that The SIOP Model was developed to assist mainstream teachers in using research-based practices which ensure ELLs success with academic language and vocabulary. Over time, the model has proven to be a form of best practices for educators. It is also known to reach ELLs by focusing on academic language in order to obtain optimal results. Learning foreign languages in the context of intercultural paradigm has great potential for personal development. It is determined that professional mobility and competence are interdependent. The curriculum should include a cultural component, on the basis of which intercultural communication competence is formed. It is revealed that in the process of forming professional mobility it is very important to distinguish personal characteristics that provide mobility, activity and creativity of a person. The pedagogical conditions of professional mobility with the help of foreign languages are outlined. It is determined that the process of learning foreign languages is aimed at forming elements of general cultural and professional competences. Good command of a foreign language enables future professionals to effectively carry out their professional activities in their field, which will significantly increase the level of language training. It is considered that the formation of communication skills at the present stage implies the development of students' communicative competence. The component of directions of formation of multicultural communicative competence in the conditions of studying foreign languages for professional purposes is considered. Conclusion. The purpose of teaching foreign languages for future non-linguistic specialists with the application of the SIOP Model should upgrade the skills and abilities that allow the future specialist to effectively pursue a professional activity in their field: work with foreign literature, participate in discussions in a foreign language, speak or write a professional translation of business literature in professional field. The process of foreign languages learning with the implementation of SIOP Model is aimed at forming professional competencies. The combination of these competencies in the future will determine the level of training future professionals, the degree of their readiness for professional self-determination and professional activity. The SIOP components and functions demonstrate a number of aspects that make a teacher's performance effective. The SIOP Model combines the features of effective learning into one whole, integrates a foreign language with professional learning that in the context of modern Ukrainian education is especially relevant in the transition to a system of training future specialists.

Analyzing corruption is a topic of interest to many and is indeed very complex due to its inherent difficulties with its identification and quantification. Past studies present several variables, indices, computational models, and approaches, but their relevance in the fourth industrial revolution (Industry 4.0) has been debatable. This chapter addresses the need to revisit the mathematical models and approaches in the Industry 4.0 context. The chapter provides a foundation for this argument through a compressive literature review followed by a proposal of a three-stage concept for corruption identification. The chapter illustrates two case studies from which a strong justification derives for considering the digital transformation and use of big data to deal with corruption and improve the external and internal perceptions about corruption in general.

The introduction provides the historical background and sets the stage for the music-theatrical developments that the following chapters will address in detail. It explains in general terms the reasons for a number of administrative choices made early in the colonization, which had a profound impact in fomenting the sociocultural environment in which music and theatrical arts flourished. It advances the main arguments of the book, stressing that the circulation of repertory and artists between metropolis and colony was a two-way road, and local artists exercised relative agency in adapting old models and forging new paradigms. It concludes by providing an overview of the book.

The article highlights research, dedicated to the study of the peculiarities of justification of the projects in the emerging space debris market in the age of New Space. It has been proved that human-induced debris in orbital space has reached catastrophic proportions, which requires making immediate changes for sustainable development of space activity. The research objective resides in the development of theoretical and methodological foundations, scientific and methodological approaches, and a practical toolkit for justifying projects in the emerging space debris market. The methodological platform of the research included the Stakeholder concept as an eco-system of interrelated groups. One built the BCG matrix of growth of the “Access to outer space” sector of the global market of space products and services. Also, there were distinguished four groups of space services for this segment using two factors – “the share of the types of space services” and “the relative share of the service market.” During the research, the authors developed a matrix for analysis of the project stakeholders in the emerging space debris market. It has been identified that there are three groups of stakeholders by the factors’ levels “Influence – Interest”: partners – alpha-stakeholders ( -stakeholders), consultants and support – beta-stakeholders ( -stakeholders). A situational model for the choice of a negotiating strategy for the development of projects in the space debris management market has been developed based on the methodological approach of “decision tree” to determine a rational negotiating strategy for reduction of destructive behaviour and avoidance of organizational conflicts among residential stakeholders. It was proposed to determine the general efficiency of the projects in the emerging space debris market based on the methodology by M. Farrell: as production of technical effectiveness and allocative (distributional) efficiency. All components of general efficiency were analyzed by the authors who also provided analytical calculation formulae: technical, economic, social, and ecological. A method of determining expenditures for a project on emerging space debris on the assumption of an alternative cost of projects and determining the stage of the project’s life cycle has been proposed. Making decisions on the project development requires structural analysis of expenditures of operating activity by the life cycle stages. To do that, the operating activity costs should be structures in the following way: preproduction costs; production costs; off-production costs; postproduction costs. The following main parameters used for making managerial decisions during project development were considered: profitability, the cost of deferred decisions, and deviation from costs. It was discovered that project development is carried out in the risk and uncertainty conditions. The authors formed a system for assessing risks, related to financing of the projects on recycling of space debris, which grounds on risks classification (technical, financial, procedural), which enabled the possibility to develop risk management strategies. The risk groups were analyzed following the requirements of stakeholders.

Analyses of first stage nozzle cracking in General Electric Model 7001B and 7001E industrial gas turbines are presented. Empirical algorithms are developed to predict the maximum extent of cracking that is visible on these nozzles as a function of engine cyclic history and the number of fired hours. It is shown that the algorithms predict this cracking to within a factor of two. Metallurgical analyses of nozzles show that crack growth follows the carbide-matrix interface, environmental attack occurs at the crack tip, and that the microstructure changes by increasing the amount of carbide precipitation which increases the hardness. These metallurgical results, along with mechanical test data and stress analyses from the literature, are used to understand the nature of nozzle cracking. The maximum extent of cracking coincides with locations of maximum thermal stresses as determined by finite element analyses of similar nozzle designs. This location is at the airfoil-shroud junction on the middle vanes of multi-vane castings. The use of these algorithms as a predictive maintenance tool and the ability to visually inspect nozzles in the engine also are discussed.

Use of the average passage equations for simulating the steady flow in multistage tarbomachinery has been limited in practice to H-type meshes with a “pure” or “strict” character in which pitchwise mesh lines have no axial or radial variation. This requirement is due to the original implementation of the model for the deterministic component of the Adamczyk stress tensor which closes the average passage equations. Such meshes can be highly distorted, especially near blunt leading edges or around highly staggered airfoils. A more general implementation of the closure model is developed which permits the use of general meshes of varying topology and character and exploits the conservation properties of the underlying CFD algorithm. The derivation of the new implementation is based on the FAS multigrid forcing function construction and is identical to the original implementation when applied to pure H-meshes. An isolated cascade simulation is presented which demonstrates a typical improvement in accuracy when non-pure H-meshes are employed. Also, results for a two and one half stage research turbine are presented which employed the new closure implementation and show some of the other benefits of using more general grids, namely improved convergence rate and reduced computation times.

Customers’ choice decisions often involve two stages during which customers first use noncompensatory rules to form a consideration set and then make the final choice through careful compensatory tradeoffs. In this work, we propose a two-stage network-based modeling approach to study customers’ consideration and choice behaviors in a separate but integrated manner. The first stage models customer preferences in forming a consideration set of multiple alternatives, and the second stage models customers’ choice preference given individuals’ consideration sets. Specifically, bipartite exponential random graph (ERG) models are used in both stages to capture customers’ interdependent choices. For comparison, we also model customers’ choice decisions when consideration set information is not available. Using data from the 2013 China auto market, our results suggest that exogenous attributes (i.e., car attributes, customer demographics, and perceived satisfaction ratings) and the endogenous network structural factor (i.e., vehicle popularity) significantly influence customers’ decisions. Moreover, our results highlight the differences between customer preferences in the consideration stage and the purchase stage. To the authors’ knowledge, this is the first attempt of developing a two-stage network-based approach to analytically model customers’ consideration and purchase decisions, respectively. Second, this work further demonstrates the benefits of the network approach versus traditional logistic regressions for modeling customer preferences. In particular, network approaches are effective for modeling the inherent interdependencies underlying customers’ decision-making processes. The insights drawn from this study have general implications for the choice modeling in engineering design.

In this paper, the author presents a cost model which simultaneously incorporates the abilities of two main designs. Namely, design for reliability (DfR) and design for maintainability (DfMn). DfR and DfMn have been of a great concern for designers. The focus has been more on the quality rather than aspects of reliability and maintainability of product development in general and product design in particular. However, as more awareness and attention is paid to the whole product lifecycle, more product lifecycle X-ability needs to be considered upfront at the design stage. To develop a new model, cost models of design for reliability as well as design for maintainability have been considered and evaluated. This new model, which tackles the two criteria simultaneously, has been developed and is a parametric model which allows for running sensitivity analysis based on the different aspects of reliability and maintainability.

This paper presents a comparison of 2D unsteady Reynolds Averaged Navier-Stokes (RANS) simulations using two standard turbulence models, i.e. RNG k-ε and a Reynolds Stress Transport Model, with experimental data, obtained using two-dimensional Particle Image Velocimetry (PIV) measurements within an entire stage of an axial turbomachine. The computations are performed using the commercial flow solver FLUENT™. A sliding mesh interface between the rotor and stator domains is used. The PIV measurements are performed in a refractive-index-matched facility that provides unobstructed view, and cover the entire 2nd stage of a two-stage axial pump. The inlet velocity and turbulence boundary conditions are provided from the experimental data. Detailed side-by-side comparisons of computed and measured phase-averaged velocity as well as turbulence fields within the entire stage are presented. Quantitative comparisons between the experiments and the computations are also included in terms of line distributions within the rotor-stator gap and the stator wake regions. The results show that, although there is reasonable agreement in general between the experimental results and the computational simulations, some critical flow features are not correctly predicted. The turbulent kinetic energy levels are generally too high in the simulations, with substantial amount of unphysical turbulence generation near the blade leading edges, especially in the case of RNG k-ε model.

Two kinds of three-dimensional model are built to simulate the gas entrainment process through a small break in the horizontal coolant pipe at the bottom of the stratified flow. The results were compared with the two-dimensional simulation results and the experimental data. In terms of the two-phase distribution, the simulation results agree well with the experimental data and show much superiority compared with the two-dimensional model. The results verify the reliability of model building, condition setting and calculating method qualitatively and quantitatively. In general, after gas entrainment, the average velocity over cross section increases obviously, but the mass flow rate decreases contrarily. This is because that void fraction meanwhile reduces the fluid density. In addition, it is found that the larger the void fraction of vapor is, the higher the average discharge velocity of the fracture cross-section fluid is. Besides, with the larger internal and external pressure difference, the gas volume fraction and the flow velocity in the break increase, resulting in the mass flow rate increasing along with them. However, since the critical height increases as well, the total loss amount of liquid in the stable effluent stage decreases, and the time before entrainment becomes shorter.

Parts with complex geometry can be produced by additive manufacturing processes without a significant increase in fabrication time and cost. One application of AM technologies is to fabricate customized lattice-skin structures which can enhance the functional performance of products with less material and less weight. In this paper, a brief comparison between different types of lattice structures and their related design methods has been done. The result shows that conformal lattice structures may perform better than other types of lattice due to its unique configuration for some design cases. However, most existing design methods of conformal lattice have a limitation to deal with complex external geometry. To solve this issue and fully utilize conformal lattice structures, a general design method for a conformal lattice-skin structure is proposed. This design method consists of two major design stages. At the beginning design stage, conformal surfaces are selected based on proposed general design guidelines. Then two different lattice frame generation methods are provided to generate conformal lattice to fit the selected conformal surfaces. A comparison between these two methods is made to help designers select a suitable method for their design cases. In the second design stage, the thickness of each lattice strut is calculated based on a defined mapping function. This mapping function generally considers two important factors from the result of topology optimization. They are optimal relative density distribution and its related principle stress direction. Based on the calculated strut’s thickness, the geometry model of heterogeneous conformal lattice can be generated. At the end of the design process, skin structures can be added on the generated heterogeneous conformal lattice. To further illustrate and validate the proposed design method, a design case of handle connector is provided. The result of this case study shows this method can provide an efficient tool for designers to generate the conformal lattice-skin structure for a complex external shape.

We propose a novel method to merge convolutional neural-nets for the inference stage. Given two well-trained networks that may have different architectures that handle different tasks, our method aligns the layers of the original networks and merges them into a unified model by sharing the representative codes of weights. The shared weights are further re-trained to fine-tune the performance of the merged model. The proposed method effectively produces a compact model that may run original tasks simultaneously on resource-limited devices. As it preserves the general architectures and leverages the co-used weights of well-trained networks, a substantial training overhead can be reduced to shorten the system development time. Experimental results demonstrate a satisfactory performance and validate the effectiveness of the method.
