Books on the topic 'Dynamics in AZO'

INFORUM is a research project started more than forty five years ago by Clopper Almon. The focus is on the development of dynamic, interindustry, macroeconometric models to forecast the economy in the long run. Over the last 30 years, the Inforum approach to model building has been shared by economists in many different countries. Researchers have focused much of their efforts to developing a linked system of international interindustry models with a consistent methodology. A world-wide network of research associates use similar methods and a common software obtaining comparable results to produce studies of common interest to the group. Inforum partners have shared their research in an annual conference since 1993. The XXII Inforum World Conference was held in Alexandria, Virginia in September 2014 and this book contains a selection of papers presented during the sessions. All these contributions share an empirical and pragmatic orientation that is very useful for policymakers, business, and applied economists. Some papers are devoted to specific topics (productivity, energy, international trade, demographic changes) and some others are oriented to model building and simulations.

Chapter 2 provides background information pertaining to the regulation of takeover bids, to clarify how political struggles surrounding shareholder rights elucidate the political dynamics of marketization. Four considerations motivated the case selection. First, the so-called market for corporate control cannot arise spontaneously and is prone to market failure, because corporate control is a fictitious good in need of commodification by means of market-enabling rules. Second, the rules governing this market are politically contentious because they have significant distributional implications. Third, struggles surrounding these rules pit different kinds of equally well-endowed profit-oriented opportunists against one another. Fourth, the process started a long time ago and played out differently in different countries, partly due to variation in the political salience of hostile bids.

Just a few decades ago, chemical oscillations were thought to be exotic reactions of only theoretical interest. Now known to govern an array of physical and biological processes, including the regulation of the heart, these oscillations are being studied by a diverse group across the sciences. This book is the first introduction to nonlinear chemical dynamics written specifically for chemists. It covers oscillating reactions, chaos, and chemical pattern formation, and includes numerous practical suggestions on reactor design, data analysis, and computer simulations. Assuming only an undergraduate knowledge of chemistry, the book is an ideal starting point for research in the field. The book begins with a brief history of nonlinear chemical dynamics and a review of the basic mathematics and chemistry. The authors then provide an extensive overview of nonlinear dynamics, starting with the flow reactor and moving on to a detailed discussion of chemical oscillators. Throughout the authors emphasize the chemical mechanistic basis for self-organization. The overview is followed by a series of chapters on more advanced topics, including complex oscillations, biological systems, polymers, interactions between fields and waves, and Turing patterns. Underscoring the hands-on nature of the material, the book concludes with a series of classroom-tested demonstrations and experiments appropriate for an undergraduate laboratory.

Minoan Crete is rightly famous for its idiosyncratic architecture, as well as its palaces and towns such as Knossos, Malia, Gournia, and Palaikastro. Indeed, these are often described as the first urban settlements of Bronze Age Europe. However, we still know relatively little about the dynamics of these early urban centres. How did they work? What role did the palaces have in their towns, and the towns in their landscapes? It might seem that with such richly documented architectural remains these questions would have been answered long ago. Yet, analysis has mostly found itself confined to building materials and techniques, basic formal descriptions, and functional evaluations. Critical evaluation of these data as constituting a dynamic built environment has thus been slow in coming. This volume aims to provide a first step in this direction. It brings together international scholars whose research focuses on Minoan architecture and urbanism as well as on theory and methods in spatial analyses. By combining methodological contributions with detailed case studies across the different scales of buildings, settlements and regions, the volume proposes a new analytical and interpretive framework for addressing the complex dynamics of the Minoan built environment.

This chapter discusses the interaction between currents and magnetization, which can cause undesirable effects such as enhanced magnetic noise in read heads made from magnetic multilayers. While most research has been carried out on metallic structures, current-induced magnetization dynamics in semiconductors or even insulators has been pursued as well. These issues have attracted many physicists because, on top of the practical aspects, the underlying phenomena are fascinating. Berger and Slonczewski are acknowledged to have started the field in general through their introduction of the concept of current-induced magnetization dynamics by the transfer of spin. The reciprocal effect, i.e., spin pumping, was expected long ago, but it took some time before Tserkovnyak et al. developed a rigorous theory of spin pumping for magnetic multilayers, including the associated increased magnetization damping.

Organizations that function across dissimilar nations and cultures are known as global organizations. Their origins may be in any of the globalized countries of the World Trade Organization as well as other supernational systems that coordinate activities of the United Nations and similar organizations. Global organizations are everywhere, and their growth has been phenomenal since World War II. Managing them effectively requires in-depth knowledge of the political and economic geography in which they operate. Along with such knowledge, managers must also discern the underpinnings of cultural and technological developments in their strategic planning and implementation. A few decades ago, an interdisciplinary perspective was not regarded as crucial in understanding the functioning of global organizations. However, in the complex and dynamic era of globalization, an interdisciplinary perspective is crucial. This book adopts this perspective and integrates the often conflicting and dynamic perspectives in a fashion that sheds light for understanding the nature of global organizations in the twenty-first century.

In this prologue, I comment on key events in the history of research on metamemory and on my own reactions to those events—beginning with the now-famous research on feeling-of-knowing judgments carried out by Joe Hart 50 years ago when Joe and I were both graduate students at Stanford University. After speculating on why mainstream memory researchers, me in particular, were slow to realize the importance of research on metacognitive processes, even after John Flavell and Henry Wellman had provided an elegant definition of the field during the 1970s, I discuss the events and dynamics that ultimately made it clear that understanding metacognitive processes is a critical component of understanding human learning and memory processes more broadly.

This chapter deals with the “great oxidation event” (GOE), which represents a quantum shift in the oxygen content of the atmosphere. It suggests that the GOE represents the evolution of cyanobacteria. According to the geologic record, the oxygen content of Earth's atmosphere increased dramatically around 2.3 billion years ago. Since cyanobacteria likely evolved much earlier, it does not appear that a well-oxygenated atmosphere is a necessary or immediate consequence of the activities of oxygen-producing organisms. Atmospheric chemistry is a slave to the dynamics of the mantle, as the interior and exterior of the planet are connected in a profound way. Indeed, it took half of Earth's history for the mantle to quiet to point where oxygen could accumulate. This, however, represented a watershed, a tipping point if you will, where the chemistry of Earth's surface was forever altered.

By definition, a team is two or more people who are working together. Teamwork can be thought of as the dynamic behaviors, cognitions, attitudes, and skills that allow a team to perform its stated goal. Concerning healthcare teamwork, nearly two decades ago, the Institute of Medicine issued the report To Err Is Human, which identified teamwork as a key target for improving the quality and safety of patient care. Over the last twenty-five years, crisis resource management has become synonymous with a style of teamwork and performance epitomized by healthcare providers in high acuity, time-pressured environments such as acute care practice. This chapter discusses the major themes of crisis resource management.

This chapter discusses how Communism continues to generate the same kind of debates that divided the left, and the left from the right, more than half a century ago. In some instances, documents flowing out of the Moscow archives have helped shed new light on the politics and affiliations of an Alger Hiss or a Harry Bridges. However, such revelations are hardly needed to keep this pot boiling, because the real issue involves the fate, character, and legitimacy of the American radical tradition, especially during that moment in the middle decades of the twentieth century when the Communists were at their influential apogee within a dynamic new trade union movement, as well as in almost every other area of progressive U.S. politics.

This article focuses on the dynamics of interpreting oral history through digital technologies. From today's vantage point, my “high-tech” strategies are quaint and rather obsolete. Faculty have more sophisticated electronic tools at our disposal for oral history instruction, including digital transcription programs, multimedia programs that integrate voice, image, and word, and learning management systems where we can post course materials, communicate with students, organize group communication and so on. In addition to advances in teaching technologies, today's students come with higher degrees of technological literacy than a decade ago. They are equipped with computers, iPods, and cell phones, and many know how to use digital audio and video recorders. Where once we had to teach how to use specialized software programs, faculty now take for granted that students know how to make slide presentations. Some are already familiar with sound or video editing processes, and a few may even have multimedia production experience.

Surveying the history of Native Americans of the South from ancient times through the early twenty-first century, this chapter draws on oral tradition, material culture, climatology, and historical documents. Like all Native North Americans, Southern Indians have a dynamic past. They repeatedly adapted their societies to meet challenges arising from climate change 10,000 years ago, population growth during the Mississippian era, population collapse due to the introduction of new diseases following contact, warfare, and slaving in the colonial era, Indian removal, and ongoing US racial discrimination and imperialism. While pointing out diversity within the region, as well as the ties that linked Southern Indians to other people and places over time, this chapter also marks the cultural characteristics that make Native peoples of the South a distinctive group, namely their traditions of matrilineal kinship, dense populations, their long history of agriculture, and distinctive art forms and architecture.

This book dives deep into the lives of Muslim American advocacy groups in the post-9/11 era, asking how they form and function within their broader community in a world marked by Islamophobia. Bias incidents against Muslim Americans reached unprecedented levels a few short years ago, and many groups responded through action — organizing on the national level to become increasingly visible, engaged, and assertive. This book draws on more than four years of participant observation and interviews to examine how Muslim American organizations have sought to access and influence the public square and, in so doing, forge a political identity. The result is an engaging and unique study, showing that policy advocacy, both foreign and domestic, is best understood as a sphere where Muslim American identity is performed and negotiated. The book offers ever-timely insight into the place of Muslims in American political life and, in the process, sheds light on one of the fastest-growing and most internally dynamic American minority groups.

In early 2019, the Islamic Republic of Iran marked its fortieth anniversary, despite decades of isolation, political pressure, sanctions and war. Observers of its security policies continue to try and make sense of this unlikely endurance. Though there are significant disagreements about the Islamic Republic’s thinking and intentions, virtually everyone agrees that its policies are fundamentally different from those pursued by their monarchical predecessors. No Conquest, No Defeat offers a historically grounded overview of Iranian national security. Tabatabai argues that Iranian strategic thinking is perhaps best characterised by its dynamic yet resilient nature, one that is continually evolving and whose foundations were laid out decades ago. To understand Iran’s national security thinking and policies today, one must examine them in their historical context. As the Islamic Republic enters its fifth decade, this book sheds new light on Iran’s controversial nuclear and missile programmes, and its involvement in Afghanistan, Iraq, Lebanon, Syria and Yemen.

The Oxford World History of Empire, Vol. 2: The History of Empires tracks the protean history of political domination from the very beginnings of state formation in the Bronze Age up to the present. Case studies deal with the full range of the historical experience of empire, from the realms of the Achaemenids and Ašoka to the empires of Mali and Songhay, and from ancient Rome and China to the Mughals, American settler colonialism, and the Soviet Union. Forty-five chapters detailing the history of individual empires are tied together by a set of global synthesizing surveys that structure the world history of empire into eight chronological phases. Only a few decades ago empire was believed to be a thing of the past; now it is clear that it has been and remains one of the most enduring forms of political organization and power. We cannot understand the dynamics and resilience of empire without moving decisively beyond the study of individual cases or particular periods, such as the relatively short age of European colonialism. The history of empire, as this volume amply demonstrate, needs to be drawn on the much broader canvas of global history.

Since the end of the 1980s in India, self-styled representatives of a variety of ascriptive groups (religious, caste, regional, and linguistic among others) have come to routinely damage artwork, disrupt their exhibition, and threaten and assault artists and their supporters. Often, these acts are said to be a protest against the allegedly ‘hurtful’ or ‘offensive’ artworks. They are even claimed to be a prescient call to save the identity of the community, in a manner that makes the communal identities hinge entirely on that artistic (mis)representation. Yet, at the time of these attacks, many who indulge in this kind of violence have seldom heard of the artist before or even seen, read, watched, let alone engaged with the artwork. Such is the wrench on the right to freedom of speech and expression in general, and on the physical safety and security of artists in particular, that has inspired fear, anger, and discomfort within the art world, marked by ominous declarations of a ‘cultural emergency’ owing to the loss of lives and property, and without the due processes of law—a consequence that was hardly synonymous with art practice in India, at least until a few decades ago. This book tells the story of violence against artists in India, marked by the intensifying sense of insecurity, fear, frustration, and anger within the art world. But to bring out its complexities—to build an analytical account for understanding what such destructive and even competitive attacks on artists convey about India’s liberal democracy, given that violence in its many avatars has not so much been an aberration to the form of India’s liberal democracy as much as its very condition—the book attempts to map the concrete political transformations that have informed its dynamic unfolding. In other words, as opposed to simply adding to the prevalent commentaries on violent regulation of free speech in India, this work focusses on the dynamics of violence in that regulation. Based on extensive interactions with assailants and artists, I argue that these attacks are not simply ‘anti-democratic’. But are dependent in perverse ways on the very logics of democracy’s functioning, as much they are contained by it, along with the wider material conditions that have prevented both free speech in India, and India at large, from being immutably locked in a downward spiral.

Smallholder-friendly messages, albeit not always translated into action, returned strongly to the development agenda over a decade ago. Smallholders’ livelihoods encompass social and economic realities outside agriculture, however, providing opportunities as well as challenges for the smallholder model. While smallholders continue to straddle the farm and non-farm sectors, the notion of leaving agriculture altogether appears hyperbolic, given the persistently high share of income generated from agriculture noted in the Afrint dataset. Trends over the past fifteen years can be broadly described as increasing dynamism accompanied by rising polarization. Positive trends include increased farm sizes, rising grain production, crop diversification, and increased commercialization, while negative trends include stagnation of yields, persistent yield gaps, gendered landholding inequalities, gendered agricultural asset inequalities, growing gendered commercialization inequalities, and an emerging gender gap in cash income. Regional nuances in trends reinforce the need for spatial contextualization of linkages between the farm and non-farm sectors.

Semantics is the systematic study of linguistic meaning. The past fifty years have seen an explosion of research into the semantics of natural languages. There are now sophisticated theories of phenomena that were not even known to exist mere decades ago. Much of the early work in natural language semantics was accompanied by extensive reflection on the aims of semantic theory, and the form a theory must take to meet those aims. But this meta-theoretical reflection has not kept pace with recent theoretical innovations. The aim of this volume is to re-address these questions concerning the foundations of natural language semantics in light of the current state-of-the-art in semantic theorizing. The volume addresses a range of foundational questions about formal semantics: what is the best methodology for semantic theorizing, and should experimental techniques play a crucial role? How should we understand the use of formal tools such as model theory, and are there better formal alternatives? How should we think about compositionality? What does semantic theory tell us about the language faculty or linguistic competence? What are the advantages of dynamic semantics? How do formal semantic theories relate to philosophical notions of context, content, interpretation, and propositions?

Chapter 12 introduces Graphene, which is a two-dimensional “Dirac-like” material in the sense that its energy spectrum resembles that of a relativistic electron/positron (hole) described by the Dirac equation (having zero mass in this case). Its device-friendly properties of high electron mobility and excellent sensitivity as a sensor have attracted a huge world-wide research effort since its discovery about ten years ago. Here, the associated retarded Graphene Green’s function is treated and the dynamic, non-local dielectric function is discussed in the degenerate limit. The effects of a quantizing magnetic field on the Green’s function of a Graphene sheet and on its energy spectrum are derived in detail: Also the magnetic-field Green’s function and energy spectrum of a Graphene sheet with a quantum dot (modelled by a 2D Dirac delta-function potential) are thoroughly examined. Furthermore, Chapter 12 similarly addresses the problem of a Graphene anti-dot lattice in a magnetic field, discussing the Green’s function for propagation along the lattice axis, with a formulation of the associated eigen-energy dispersion relation. Finally, magnetic Landau quantization effects on the statistical thermodynamics of Graphene, including its Free Energy and magnetic moment, are also treated in Chapter 12 and are seen to exhibit magnetic oscillatory features.

Citizenship is a major feature of contemporary national and international politics. It is also a legacy of ancient Greece. The concept of membership of a community appeared in Greece some three millennia ago as a participation in the social and political life of small-scale communities, but only towards the end of the fourth century BC did Aristotle offer the first explicit statement about it. Though long accepted, the Aristotelian definition remains deeply rooted in the philosophical and political thought of the classical period, but it probably fails to account accurately for the previous centuries or the dynamics of the emergent cities. Focusing on archaic Greece, this collective enquiry, bringing together renowned international scholars, aims at exploring new routes to archaic citizenship, exemplifying the living diversity of approaches to archaic Greece and to the Greek city. If the Aristotelian model has long been applied to all Greek cities regardless of chronological issues, historians are now challenging Aristotle’s theoretical definition and are looking for other ways of conceiving citizenship and community, setting the stage for a new image of archaic cities, which are no longer to be considered as primitive or incomplete classical poleis. Driven by this same objective, the essays collected here have not, however, been tailored to endorse any specific view. Each contributor brings his or her own national background and approaches to archaic citizenship through specific fields of enquiry (law, descent, cults, military obligations, associations, civic subdivisions, athletics, commensality, behaviours, etc.), often venturing off the beaten track.

Millions of years ago, the North American continent was dragged over the world's largest continental hotspot, a huge column of hot and molten rock rising from the Earth's interior that traced a 50-mile wide, 500-mile-long path northeastward across Idaho. Generating cataclysmic volcanic eruptions and large earthquakes, the hotspot helped lift the Yellowstone Plateau to more than 7,000 feet and pushed the northern Rockies to new heights, forming unusually large glaciers to carve the landscape. It also created the jewel of the U.S. national park system: Yellowstone. Meanwhile, forces stretching apart the western U.S. created the mountainous glory of Grand Teton National Park. These two parks, with their majestic mountains, dazzling geysers, and picturesque hot springs, are windows into the Earth's interior, revealing the violent power of the dynamic processes within. Smith and Siegel offer expert guidance through this awe-inspiring terrain, bringing to life the grandeur of these geologic phenomena as they reveal the forces that have shaped--and continue to shape--the greater Yellowstone-Teton region. Over seventy illustrations--including fifty-two in full color--illuminate the breathtaking beauty of the landscape, while two final chapters provide driving tours of the parks to help visitors enjoy and understand the regions wonders. Fascinating and informative, this book affords us a striking new perspective on Earth's creative forces.

This book takes an idea first explored by Medieval logicians 800 years ago and revisits it armed with the tools of contemporary linguistics, logic, and computer science. The idea—the Holy Grail of the Medieval logicians—was the thought that all of logic could be reduced to two very simple rules that are sensitive to logical polarity (for example, the presence and absence of negations). Ludlow and Živanović pursue this idea and show how it has profound consequences for our understanding of the nature of human inferential capacities. They also show its consequences for some of the deepest issues in contemporary linguistics, including the nature of quantification, puzzles about discourse anaphora and pragmatics, and even insights into the source of aboutness in natural language. The key to their enterprise is a formal relation they call “p-scope”—a polarity-sensitive relation that controls the operations that can be carried out in their Dynamic Deductive System. They prove that the resulting deductive system is complete and sound. The result is a beautiful formal tapestry in which p-scope unlocks important properties of natural language, including the property of “restrictedness,” which they prove to be equivalent to the semantic notion of conservativity. More than that, they show that restrictedness is also a key to understanding quantification and discourse anaphora, and many other linguistic phenomena.

The term “Orientalism” reduces Islam and Muslims to stereotypes of ignorance and violence, in need of foreign control. In scholarly discourse, it has been used to rationalize Europe’s colonial domination of most of the Muslim world and continued American-led interventions in the postcolonial period. In the past thirty years it has been represented by claims that a monolithic Islam and equally monolithic West are distinct civilizations, sharing nothing in common and, indeed, involved in an inevitable “clash” from which only one can emerge the victory. Most recently, it has appeared in alt-right rhetoric. Anti-Muslim sentiment, measured in public opinion polls, hate crime statistics, and legislation, is reaching record levels. Since John Esposito published his first book nearly forty years ago, he has been guiding readers beyond such politically charged stereotypes. This Festschrift highlights the contributions of scholars from a variety of disciplines who, like—and often inspired by—John Esposito, recognize the misleading and politically dangerous nature of Orientalist polarizations. They present Islam as a multifaceted and dynamic tradition embraced by communities in globally interconnected but substantially diverse contexts over the centuries. The contributors follow Esposito’s lead, stressing the profound commonalities among religions and replacing Orientalist discourse with holistic analyses of the complex historical phenomena that affect developments in all societies. In addition to chapters focusing on diversity among Muslims and interfaith relations, this collection includes chapters assessing the secular bias at the root of Orientalist scholarship, and contemporary iterations of Orientalism in the form of Islamophobia.

Since its inception more than a century ago, Hong Kong cinema has been a pre-eminent form of local entertainment and a site of ideological contentions propelled by colonial, national and international politics at different historical junctures. The Other Side of Glamour is a study of the historical development of the left-wing film establishment in Hong Kong. In particular, it seeks to reconstruct a more dynamic picture of left-wing film production through closer attention to the entwinement of ideological, artistic, institutional and corporate agendas that informed the practices of filmmakers on both sides of the political divide. The inquiry is informed by the following questions: What does it mean to be on the “left” of the Hong Kong film industry during the Cold War era? How did the left-wing studios balance their artistic, ideological, and commercial agendas in their production and exhibition strategies? What makes a film “left-wing” or “right-wing”? How did national, colonial, and international politics intervene in the ‘making of’ the popular left-wing cinema in Hong Kong? How did the left-wing film establishment in Hong Kong reinvent itself in the post-Cold War, post-Cultural Revolution era? What are the nuanced legacies of the classical left-wing in Hong Kong cinema today? It argues that the left-wing’s institutional character and corporate strategies in the making of a ‘popular left-wing cinema’ are indispensable to an understanding of their nuanced (and often overlooked) legacy in Hong Kong cinema today.

Os contextos pandémico e pós-pandémico vêm impondo às cidades outras dinâmicas, outros sons, outros ecos, outros percursos, outros visitantes humanos e não humanos. Durante o confinamento, o encerramento de espaços teatrais e expositivos – bem como, durante o desconfinamento, as limitações para a sua utilização - têm tido consequências penosas nas programações artísticas e efeitos dramáticos nos quotidianos dos seus agentes (artistas, técnicos, programadores, curadores, etc.). Ao mesmo tempo, a desaceleração da vida da cidade (do trânsito, do ritmo nas ruas, do frenesim produtivo e de consumo, etc.) veio contribuir beneficamente para uma diminuição das emissões de CO2. Neste quadro, a cidade - mais concretamente as suas zonas públicas a céu aberto – surgem mais nitidamente como espaços de circulação e de interferência (ou de suspensão de interferência) entre pessoas. O que aprendemos com a experiência de confinamento e desconfinamento? Em primeiro lugar, que a cidade tem uma densidade flutuante, na medida em que as concentrações populacionais se esvaem quando nos encerramos em casa. Em segundo lugar, que o encontro com o outro (uma das prerrogativas da cidade) pode acontecer em outras escalas que não apenas a dimensão cultural. Em terceiro lugar, que o medo pode ser um sentimento público capaz de fazer implodir as próprias cidades, se não for transformado numa força para a vida. Como é que, neste processo, os artistas se organizam e se constituem como agentes na cidade? Como é que a cidade passou a ser representada? Que cidade é aquela que desejamos? Este congresso surge assim da necessidade de intensificar o diálogo entre a cidade e a arte, em particular as artes performativas. Este encontro efoi o culminar de dois anos de investigação consistente e consolidada no âmbito do projecto TEPe (Technologically Expanded Performance). Ao longo destes dois anos, desenvolvemos atividades com a comunidade com o intuito de promover um diálogo intercultural e transdisciplinar, e proporcionar o encontro com vivências urbanas variadas. Através das diferentes propostas de percursos pela cidade, mapeámos acontecimentos, hoje invisíveis, mas ainda assim presentes: desde “memórias soterradas” a “caminhadas sensoriais”, passando por registos íntimos de confinamento. O encontro visou partilhar as experiências realizadas com a contribuição de duas equipas: a portuguesa, em Lisboa, e a brasileira, em Fortaleza. Para além de apresentarmos as conclusões das pesquisas realizadas, lançamos esta chamada para apresentações, especialmente destinada a artistas e estudiosos de performance art, historiadores das cidades, antropólogos, urbanistas, geógrafos, estudiosos da escuta e do som e a todxs aquelxs a quem interessa pensar (e projectar) a vida na cidade. -------------------------------------------------------------------------------------------------------------- The pandemic and post-pandemic contexts have imposed on cities other dynamics, other sounds, other echoes, other routes, other human and non-human visitors. During the lockdown, the closure of theatrical and exhibition spaces - as well as, during lockdown unlocking, the limitations for their use - have had painful consequences in artistic programming and dramatic effects in the daily lives of its agents (artists, technicians, programmers, curators, etc.). At the same time, the slowing down of city life (traffic, the pace of the streets, the frenzy of production and consumption, etc.) has made a beneficial contribution to a reduction in CO2 emissions. In this context, the city - and more specifically its open-air public areas - emerge more clearly as spaces for circulation and interference (or suspension of interference) between people. What have we learned from the experience of national lockdown and unlocking? Firstly, that the city has a fluctuating density, insofar as population concentrations fade when we shut ourselves indoors. Secondly, the encounter with the other (one of the prerogatives of the city) can take place on other scales than the cultural dimension alone. Thirdly, fear can be a public sentiment capable of imploding cities themselves if it is not transformed into a force for life. How, in this process, are artists organised and constituted as agents in the city? How did the city come to be represented? What kind of city do we want? This congress thus arises from the need to intensify the dialogue between the city and art, particularly the performing arts. This international meeting is the culmination of two years of consistent and consolidated research within the TEPe (Technologically Expanded Performance) project. Throughout these two years, we have developed activities with the community to promote intercultural and transdisciplinary dialogue and provide an encounter with varied urban experiences. Through the different proposals of walks through the city, we have mapped events, today invisible, but still present: from "buried memories" to "sensorial walks", passing through intimate records of confinement. The meeting aims to share the experiences carried out with the contribution of two teams: the Portuguese, in Lisbon, and the Brazilian, in Fortaleza. Besides presenting the conclusions of the researches carried out, we launch this call for presentations, especially addressed to artists and scholars of performance art, historians of cities, anthropologists, urban planners, geographers, scholars of listening and sound and to all those who are interested in thinking (and projecting) life in the city.
