We focus on the origin of myocardial cells in the first and second heart fields in splanchnic mesoderm in the early embryo. Genetic lineage tracing using Cre recombinase activated conditional reporter genes has made a major contribution to our understanding of cardiac progenitor cells and will be discussed together with other experimental approaches to analysing cell lineages at the clonal level. Interactions between myocardial, epicardial and endocardial lineages are essential for coordinated function and homeostasis of the normal heart. Perturbation of heart field development and myocardial lineage contributions to the heart through developmental or acquired pathologies results in and modulates the progression of cardiac disease. Understanding the origin of myocardial lineages during embryonic development and how they converge to generate an integrated heart is thus a major biomedical objective. Furthermore, reactivation of developmental programmes is likely to be of major importance in strategies aimed at repair of the damaged heart.

In this chapter we illustrate the signalling interactions of the endocardium with the other cardiac tissues to coordinate cardiac development. First, we describe the developmental origins of the endocardium. Then we focus on the Notch pathway because of its unique signalling activity in the endocardium, and briefly describe the elements of this signalling mechanism and the key cardiogenic processes that require endocardial Notch signalling: patterning of the early embryonic endocardium into prospective territories for valves and ventricular chambers, early valve formation, ventricular trabeculation, and compaction. Finally, we discuss how Notch dysfunction in the endocardium results in cardiac structural malformations that can lead to congenital heart disease.

This chapter describes Thurston's original path of discovery to the Nielsen–Thurston classification theorem. It first provides an example that illustrates much of the general theory, focusing on Thurston's iteration of homeomorphisms on simple closed curves as well as the linear algebra of train tracks. It then explains how the general theory works and presents Thurston's original proof of the Nielsen–Thurston classification. In particular, it considers the Teichmüller space and the measured foliation space. The chapter also discusses measured foliations on a pair of pants, global coordinates for measured foliation space, the Brouwer fixed point theorem, the Thurston compactification for the torus, and Markov partitions. Finally, it evaluates other approaches to proving the Nielsen–Thurston classification, including the use of geodesic laminations.

Although the efferent role of the autonomic nervous system (ANS) in homeostasis has long been recognized, afferent aspects of the ANS—especially interoception—are increasingly recognized to be equally important. Interoception is fundamental to the regulation of internal physiology, particularly as it is coordinated with contextually determined and adaptive behavioral processes. A cardinal but often underappreciated feature of interoception is its role in myriad cognitive and affective processes that are integrated in health and disease. This chapter introduces the concept of interoception and outlines its historical origins and applications in multiple domains of psychology and psychobiology. It provides an overview of its peripheral and central neural substrates, and it outlines how this construct is best conceptualized within a multi-system and multi-level regulatory framework.

This chapter illustrates mythic and ritual productions of time. Ritual produces regularities that are coordinated by clocks and calendars. Two basic ways of producing religious time, ancestral and mythic, represent different constructions of temporal continuity. Ancestral time, relying on memory, establishes continuity between human generations. Mythic time, transmitted in narratives of origin and destiny, establishes continuity through underlying moral, legal, or forensic relations between actions and consequences. While establishing temporal continuity, mythic time can also signal temporal ruptures in a past crisis, a present conflict, or a future apocalypse. Ritual practices and mythic narratives generate religious time, but religious timing is also crucial in other spheres of human activity, such as politics, economics, and aesthetics. Religious time, therefore, is not only or merely religious. With its regularities and regulations, its ancestral and mythic constructions of continuity, religious time is also embedded in the aesthetics, economics, and politics of time.

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.

Global legal harmonization is an aspect of transnational law whereby a family of norms is formed by a non-state legal order. Sovereign wealth funds (SWFs)—diverse in terms of their countries of origin, size, investment strategies, asset allocation tactics, and underlying purposes—contribute to the harmonization by setting and enforcing cross-border ethical norms and governance standards. This chaper examines aspects of SWFs as transnational lawmakers, a significant phenomenon for the global family of standards and a potential challenge for state-based legal orders. It examines SWF adoption of general legal principles and customs as advanced by a global civil society and through standardized contract forms and conduct codes; voluntary enactment of informal soft laws; and creation of norm-setting institutions. It concludes that SWFs are part of a diffused, multilevel, coordinated, political system that defies state-centric paradigms, contributing to the dynamism that defines transnational law while creating concerns related to legitimacy, democratic authority, and democratic deficit.

This chapter examines the attempt to coordinate and harmonize the dual-use and arms export control policies of EU member states, focusing in particular on the use of EU arms embargoes and the implementation of the EU Dual-Use Regulation and the EU Common Position on Arms Export. The chapter examines the original motivations that drove and sustained this effort and gives an assessment of its impact on member states’ national policies. In doing so, the chapter pays particular attention to the dual-use and arms export control policies of Europe’s major powers (France, Germany, the United Kingdom), highlighting areas where states’ policies have been affected by EU processes of coordination and convergence, and where they remain driven by primarily national considerations. The chapter also assesses and compares the impact of these processes among a selection of smaller EU member states.

This chapter translates an address by Justo Sierra, in which he suggests that many of Mexico’s problems are problems with national education: “The University, then, will have sufficient power to coordinate the guiding principles of national character.” Like Antonio Caso, he believes that “[t]‌o cultivate wills in order to harvest egoists would be the bankruptcy of pedagogy.” For Sierra, one’s education should be grounded in or be attentive to national circumstances: “No, the University is not a person destined never to turn its eyes away from the telescope or microscope even if the nation is falling apart around it.” And he suggests that the production of knowledge should be affirmative and original. Finally, despite his earlier sympathy with positivism, which dismisses speculative metaphysics as a source of knowledge, Sierra suggests that the success of national education requires reintroducing philosophy or metaphysics.

This chapter discusses the Schwarzschild black hole. It demonstrates how, by a judicious change of coordinates, it is possible to eliminate the singularity of the Schwarzschild metric and reveal a spacetime that is much larger, like that of a black hole. At the end of its thermonuclear evolution, a star collapses and, if it is sufficiently massive, does not become stabilized in a new equilibrium configuration. The Schwarzschild geometry must therefore represent the gravitational field of such an object up to r = 0. This being said, the Schwarzschild metric in its original form is singular, not only at r = 0 where the curvature diverges, but also at r = 2m, a surface which is crossed by geodesics.

This essay evaluates the origins, purposes, operation, and evolution of Minnesota’s sentencing guidelines system, implemented in 1980. Topics examined include key guidelines provisions, related statutes, charging and sentencing practices, departure rates, interpretive case law, and correctional populations. The essay concludes that the goals of this pioneering sentencing reform have largely been achieved: punishments have become more uniform and proportionate; policy formulation is more comprehensive and informed by data; sentencing has been coordinated with available correctional resources to avoid prison overcrowding and set priorities in the use of prison beds; there is a greater degree of “truth in sentencing;” prison sentences are used relatively sparingly; and the guidelines remain fairly simple to understand and apply. Minnesota has also achieved a sustainable balance between conflicting sentencing purposes, between uniformity versus flexibility, and in the powers of the sentencing commission, the legislature, courts, and practitioners to control sentencing policy and case outcomes.

How do contemporary Chinese audiences access art cinema? What are the alternative channels for the distribution and exhibition of art cinema in China? How is Chinese art cinema changing with the booming of internet media and commodity culture in the 21st century?To answer these questions, Xiang Fan explores the dynamic networks of art cinema in China in the 21st century, highlighting the cultural practices of intermediaries such as independent programmers, internet critics, and fan translators. Offering insights gleaned from original ethnographic research, Fan reveals how these intermediary practitioners think about cinema, negotiate judgement and appreciation, construct a discourse of value and taste, and most importantly, constitute a coordinated and interrelated network for the sharing of art cinema. She argues that although their motivation was derived from a cinephilia seeking to forge an alternative mode of distribution and reception, the ‘new’ cinema culture they have produced simultaneously negotiates a subtly complicit relationship with authoritative and market forces. In doing so, she offers an original interdisciplinary perspective on contemporary art cinema culture in Chinese society.

This volume in the Contemporary Military, Strategic, and Security Issues series presents a concise introduction to the evolution, key concepts, discourse, and future options for improved strategic communication in today's U.S. government. Strategic Communication: Origins, Concepts, and Current Debates is a groundbreaking study, the first book explicitly focused on strategic communication as it is currently used and discussed in the U.S. government. Written specifically for those who are new to strategic communication, this incisive book clarifies the definitional debate, explores the history of the term and its practice, and embraces a broad, practical definition. But that is only the beginning. Moving to the realities of the issue, author Christopher Paul reviews dozens of government reports on strategic communication and public diplomacy released since 2000, examining specific proposals related to improving strategic communication in the U.S. government and explaining the disagreements. Most important, he offers consensus and clarity for the way ahead, discussing how disparate elements of the government can be coordinated to master—and win—the "war of ideas" through fully integrated and synchronized communications and actions.

Providing up-to-date information for general readers as well as those well-informed about the Islamic State, this book offers an essential understanding of the rise of ISIS and its current influence in the Middle East as well as worldwide. ISIS—also referred to as ISIL, the Islamic State, or Daesh—began to assert its power and gain recognition for its militant and terroristic activities in April 2013. After the coordinated attacks in Paris on November 13th, 2015, ISIS has captured the full attention of observers in the West. This accessible book explains what ISIS is, what the group's goals are, what their members believe, and why their ranks are growing. Readers will gain an understanding of how ISIS is a unique group—one seeking to be the army of the righteous fighting to defeat the unbelievers and usher in the end of days—but that the extremist views of ISIS are an expression of a growing frustration with life in the Middle East and elsewhere shared by a larger community of non-state and post-state actors. The book provides an introduction that documents the origins of ISIS within the larger Al Qaeda organization during the Iraq War. The following chapters discuss the origins, development, and territorial expansion of ISIS in Syria and Iraq and examine the ideological motivations behind the emergence of ISIS, thereby enabling a nuanced understanding of the importance of ISIS in contemporary history. Other entries discuss individuals, events, and organizations that put ISIS in historical context in terms of contemporary events since the Iraq War into the present and explain the group's position within the complex conflict currently boiling in the Middle East.

In most studies of British decolonisation, the world of labour is neglected, the key roles being allocated to metropolitan statesmen and native elites. Instead this volume focuses on the role played by working people, their experiences, initiatives and organisations, in the dissolution of the British Empire, both in the metropole and in the colonies. How central was the intervention of the metropolitan Left in the liquidation of the British Empire? Were labour mobilisations in the colonies only stepping stones for bourgeois nationalists? To what extent were British labour activists willing and able to form connections with colonial workers, and vice versa? Here are some of the complex questions on which this volume sheds new light. Though convergences were fragile and temporary, this book recapture the sense of uncertainty that accompanied the final decades of the British Empire, a period when radical minorities hoped that coordinated efforts across borders might lead not only to the destruction of the British Empire but to that of capitalism and imperialism in general. Exploiting rare primary sources and adopting a resolutely transnational approach, our collection makes an original contribution to both labour history and imperial studies.

The Atlas contains maps of natural distribution areas and descriptions of perennial and annual forage grass species representating the tribe Hordeeae Mart. in the territory of the former USSR. Maps of natural distribution areas and descriptions are provided for 47 species of perennial and annual forage grasses of the following genera of the tribe: Elymus L., Agropyron Gaertn., Leymus Hochst., and Psathyrostachys Nevski. The maps were constructed using the MapInfo GIS on the original topographic base prepared by the authors. For the base map, the V.V. Alekhin's vegetation map (1961) was digitized and revised. When mapping the natural distribution areas, the coordinates of the distribution areas of the species from the herbariums of the Komarov Botanical Institute (LE) and the Vavilov Institute (WIR) (collecting site data), as well as the literature data were used. The taxonomy of species included in the Atlas corresponds to the ideas about the status of these species in the monograph “Grasses of Russia” (Tzvelev, Probatova, 2019) and the “List of vascular plants of Russia and adjacent countries” (Cherepanov, 1995). Descriptions of forage grass species in the Hordeeae tribe contain synonymy, morphological characteristics, information on ecology and distribution, and chromosome numbers. The publication is intended for botanists, ecologists, geographers, teachers and students of biological and agricultural profiles, and nature conservation specialists.

Abstract Children of different ages live in different worlds. This is partly due to learning: as children learn more and more about the world they experience it in different ways. But learning cannot be the whole story or else children could learn anything at any age—which they cannot. In a startlingly original proposal, Michael Tomasello argues that children of different ages live and learn in different worlds because their capacities to cognitively represent and operate on experience change in significant ways over the first years of life. These capacities change because they are elements in a maturing cognitive architecture evolved for agentive decision making and action, including in shared agencies in which individuals must mentally coordinate with others. The developmental proposal is that from birth infants are goal-directed agents who cognitively represent and learn about actualities; at 9–12 months of age toddlers become intentional (and joint) agents who also imaginatively and perspectivally represent and learn about possibilities; and at 3–4 years of age preschool youngsters become metacognitive (and collective) agents who also metacognitively represent and learn about objective/normative necessities. These developing agentive architectures—originally evolved in humans’ evolutionary ancestors for particular types of decision making and action—help to explain why children learn what they do when they do. This novel agency-based model of cognitive development recognizes the important role of (Bayesian) learning, but at the same time places it in the context of the overall agentive organization of children at particular developmental periods.

The Oxford Handbook of Comparative Politics offers a critical survey of the field of empirical political science through the collection of a set of articles written by forty-seven scholars in the discipline of comparative politics. Part I includes articles surveying the key research methodologies employed in comparative politics (the comparative method, the use of history, the practice and status of case-study research, and the contributions of field research) and assessing the possibility of constructing a science of comparative politics. Parts II to IV examine the foundations of political order: the origins of states and the extent to which they relate to war and to economic development; the sources of compliance or political obligation among citizens; democratic transitions, the role of civic culture; authoritarianism; revolutions; civil wars and contentious politics. Parts V and VI explore the mobilization, representation, and the coordination of political demands. Part V considers why parties emerge, and the forms they take and the ways in which voters choose parties. The text then includes articles on collective action, social movements, and political participation. Part VI opens with essays on the mechanisms through which political demands are aggregated and coordinated. This sets the agenda to the systematic exploration of the workings and effects of particular institutions: electoral systems, federalism, legislative-executive relationships, the judiciary and bureaucracy. Finally, Part VII is organized around the burgeoning literature on macro-political economy of the last two decades. This Handbook is one of The Oxford Handbooks of Political Science a ten-volume set of reference books offering authoritative and engaging critical overviews of the state of political science.

Reframing Vivien Leigh takes a fresh new look at one of the twentieth century’s most iconic stars. Focusing on Vivien Leigh as a distinctly archival subject, the book draws upon original oral history work with curators, archivists, and fan collectives and extensive research within a network of official and unofficial archives around the world to produce alternative stories about her place within film history. The study examines an intriguing variety of historical correspondence, costume, scripts, photography, props, and memorabilia in order to reframe the dominant narratives that have surrounded her life and career. While Leigh’s glamour, collaborations with Laurence Olivier, and mental health form important coordinates for any study of the star, the book foregrounds a range of alternative contexts that emphasize her creative agency, examining her off-screen labor in areas such as theatrical training, adaptation, war work, producing, protesting, and interactions with her fan base. Part I examines a variety of case studies of Leigh’s screen and stage craft as they emerge from the archive, looking at Leigh’s varied collaborations, her investment in faithful adaptations, and her vocal training. It interconnects star studies, feminist film studies, and performance studies to produce a new take on stardom as creative process rather than stardom as image. Part II turns toward unofficial archives and local museum collections, centering the work of the archivist and the amateur collector and their impact on women’s star histories. It explores Leigh’s archival afterlives as they are constructed by a range of agents and institutions beyond the “official” star archive.

Approaches towards the formal learning of piano playing with respect to musicianship is one that demands the understanding of musical concepts and their applications. Consequently, it requires the boldness to immerse oneself in performance situations while trusting one’s instincts. One needs only to cultivate an amazing ear and a good understanding of music theory to break down progressions “quickly”. Like an alchemist, one would have to pick their creative impulses from their musical toolbox, simultaneously compelling their fingers to coordinate with the brain and the music present to generate “pleasant sounds”. My exploration leading to what will be considered Keyboard Musicianship did not begin in a formal setting. Rather it was the consolidation of my involvement in playing the organ at home, Sunday school, boarding school at Presec-Legon, and playing at weekly gospel band performances off-campus and other social settings that crystalized approaches that can be formally structured. In fact, I did not then consider this lifestyle of musical interpretation worthy of academic inclusivity until I graduated from the national academy of music and was taken on the staff as an instructor in September, 1986. Apparently, what I did that seemed effortless was a special area that was integral to holistic music development. The late Dr. Robert Manford, the then director of the Academy, assigned me to teach Rudiments and Theory of Music to first year students, Keyboard Musicianship to final year students, and to continue giving Piano Accompaniment to students – just as I have been voluntarily doing to help students. The challenge was simply this; there was no official textbook or guide to use in teaching keyboard musicianship then and I was to help guide especially non-piano majors for practical exams in musicianship. What an enterprise! The good news though was that exemplifying functionalism in keyboard, organ, piano, etc. has been my survival activity off campus particularly in church and social settings.Having reflected thoroughly and prayerfully, it dawned on me that piano literacy repertoires were crafted differently than my assignments in Musicianship. Piano literacy repertoires of western music were abundant on campus but applied musicianship demanded a different approach. Playing a sonata, sonatina, mazurka, and waltzes at different proficiency levels was different from punching chords in R&B, Ballard style, Reggae, Highlife or even Hymn playing. However, there are approaches that can link them and also interpretations that can categorize them in other applicable dimensions. A “Retrospective Introspection” demanded that I confront myself constructively with two questions: 1. WHAT MUSICAL ACTIVITIES have I already enjoyed myself in that WARRANT or deserve this challenging assignment? 2. WHAT MUSICAL NOURISHMENT do l believe enriched my artistry that was so observable and Measurable? The answers were shocking! They were: 1. My weekend sojourn from Winneba to Accra to play for churches, brass bands, gospel bands and teaching of Choirs – which often left me penniless. 2. Volunteering to render piano accompaniment to any Voice Major student on campus since my very first year. 3. Applying a principle, I learnt from my father – TRANSFER OF LEARNING – I exported the functionalism of my off-campus musical activities to compliment my formal/academic work. 4. The improvisational influences of Rev. Stevenson Alfred Williams (gospel jazz pianist), Bessa Simmons (band director & keyboardist) and at Ghana Broadcasting Corporation, Mr. Ray Ellis “Afro Piano Jazz Fusion Highlife” The trust and support from lecturers and students in the academy injected an overwhelming and high sense of responsibility in me which nevertheless, guided me to observe structures of other established course outlines and apply myself with respect to approaches that were deemed relevant. Thus, it is in this light that I selected specific concepts worth exploring to validate the functionalism of what my assignment required. Initially, hymn structures, chords I, IV, V and short highlife chordal progressions inverted here and there were considered. Basic reading of notes and intense audiation were injected even as I developed technical exercises to help with the dexterity of stiff fingers. I conclude this preface by stating that, this “Instructional guide/manual” is actually a developmental workbook. I have deliberately juxtaposed simple original piano pieces with musicianship approaches. The blend is to equip learners to develop music literacy and performance proficiencies. The process is expected to compel the learner to immerse/initiate themselves into basic keyboard musicianship. While it is a basic book, I expect it to be a solid foundation for those who commit to it. Many of my former and present students have been requesting for a sort of guide to aid their teaching or refresh their memories. Though not exhaustive, the selections presented here are a response to a long-awaited workbook. I have used most of them not only in Winneba, but also at the Callanwolde Fine Arts Center (Atlanta) and the Piano Lab (Accra). I found myself teaching the same course in the 2009 – 2013 academic year in the Music Department of the University of Education, Winneba when Prof C.W.K Merekeu was Head of Department. My observation is that we still have a lot of work to do in bridging academia and industry. This implies that musicianship must be considered as the bloodline of musicality not only in theory but in practice. I have added simplified versions of my old course outlines as a guide for anyone interested in learning. Finally, I contend that Keyboard Musicianship is a craft and will require of the learner a consistent discipline and respect for: 1. The art of listening 2. Skill acquisition/proficient dexterity 3. Ability to interpret via extemporization and delivery/showmanship. For learners who desire to challenge themselves in intermediate and advanced piano, I recommend my book, “African Pianism. (A contribution to Africology)”
