This chapter introduces the structure and content of the volume and provides an overview of each chapter. It also provides definitions of maritime history, globalisation, and the differences between the study of maritime history and the study of global history. It gives an overview of recent maritime historiography and the existing intersection between maritime history and global history. It concludes by claiming that the dynamics of global trade - competition and cooperation in past and present alike - have become central to to the study of maritime history, and asserts that the contributions to this volume reflect the hypothesis.

The predictions of the Bohmian and the decoherent (or consistent) histories formulations of the quantum mechanics of a closed system are compared for histories -- sequences of alternatives at a series of times. For certain kinds of histories, Bohmian mechanics and decoherent histories may both be formulated in the same mathematical framework within which they can be compared. In that framework, Bohmian mechanics and decoherent histories represent a given history by different operators. Their predictions for the probabilities of histories therefore generally differ. However, in an idealized model of measurement, the predictions of Bohmian mechanics and decoherent histories coincide for the probabilities of records of measurement outcomes. The formulations are thus difficult to distinguish experimentally. They may differ in their accounts of the past history of the universe in quantum cosmology.

Why did Yugoslavia fall apart? Was its violent demise inevitable? Did its population simply fall victim to the lure of nationalism? How did this multinational state survive for so long, and where do we situate the short life of Yugoslavia in the long history of Europe in the twentieth century? The Complete History of Yugoslavia by Marie-Janine Calic provides a concise, accessible, comprehensive synthesis of the political, cultural, social, and economic life of Yugoslavia—from its nineteenth-century South Slavic origins to the bloody demise of the multinational state of Yugoslavia in the 1990s

The cosmic expansion history tests the dynamics of the global evolution of the universe and its energy density contents, while the cosmic growth history tests the evolution of the inhomogeneous part of the energy density. Precision comparison of the two histories can distinguish the nature of the physics responsible for the accelerating cosmic expansion: an additional smooth component - dark energy - or a modification of the gravitational field equations. With the aid of a new fitting formula for linear perturbation growth accurate to 0.05-0.2%, we separate out the growth dependence on the expansion history and introduce a new growth index parameter γthat quantifies the gravitational modification.

In a modern global historical context, scholars have often regarded piracy as an essentially European concept which was inappropriately applied by the expanding European powers to the rest of the world, mainly for the purpose of furthering colonial forms of domination in the economic, political, military, legal and cultural spheres. By contrast, this edited volume highlights the relevance of both European and non-European understandings of piracy to the development of global maritime security and freedom of navigation. It explores the significance of ‘legal posturing’ on the part of those accused of piracy, as well as the existence of non-European laws and regulations regarding piracy and related forms of maritime violence in the early modern era. The authors in Piracy in World History highlight cases from various parts of the early-modern world, thereby explaining piracy as a global phenomenon

Digital technologies, such as the Internet and Artificial Intelligence, are part of our daily lives, influencing broader aspects of our way of life, as well as the way we interact with the past. Having dramatically changed the ways in which knowledge is produced and consumed, the algorithmic age has also radically changed the relationship that the general public has with History. Fields of History such as Public and Oral History have particularly benefitted from the rise of digital culture. How does our digital culture affect the way we think, study, research and teach the past, as historical evidence spreads rapidly in the public sphere? How do digital technologies promote the study, writing and teaching of History? What should historians, students of history and pre-service history teachers be critically aware of, when swarmed with digitized or born-digital content, constantly growing on the Internet? And while these changes are now visible globally, how is the discipline of History situated within the digital transformation rapidly advancing in Greece? Finally, what are the consequences of these changes for History as a subject taught at Greek secondary schools? These are some of the issues raised in the text that follows, which is part of the course materials of the undergraduate course offered during winter semester 2020-2021 at the School University of Athens, School of Philosophy, Pedagogy, Psychology. Course Title: 'Pedagogics of History: Theory and Practice', Academic Institution: School of Philosophy-Pedagogy-Psychology, University of Athens.

We treat continuous histories within the histories approach to generalised quantum mechanics. The essential tool is the `history group': the analogue, within the generalised history scheme, of the canonical group of single-time quantum mechanics.

Working within the HPO (History Projection Operator) Consistent Histories formalism, we follow the work of Savvidou on (scalar) field theory and that of Savvidou and Anastopolous on (first-class) constrained systems to write a histories theory (both classical and quantum) of Electromagnetism. We focus particularly on the foliation-dependence of the histories phase space/Hilbert space and the action thereon of the two Poincare groups that arise in histories field theory. We quantise in the spirit of the Dirac scheme for constrained systems.
Experimental work has elucidated molecular and cellular pathways of inflammation that promote atherosclerosis. Unraveling the roles of cytokines as inflammatory messengers provided a mechanism whereby risk factors for atherosclerosis can alter arterial biology, and produce a systemic milieu that favors atherothrombotic events. The discovery of the immune basis of allograft arteriosclerosis demonstrated that inflammation per se can drive arterial hyperplasia, even in the absence of traditional risk factors. Inflammation regulates aspects of plaque biology that trigger the thrombotic complications of atherosclerosis. Translation of these discoveries to humans has enabled both novel mechanistic insights and practical clinical advances.

Forty years ago a wise, visionary man, the Wisconsin wildlife biologist and conservationist Aldo Leopold, called for “an ecological interpretation of history,” by which he meant using the ideas and research of the emerging field of ecology to help explain why the past developed the way it did. At that time ecology was still in its scientific infancy, but its promise was bright and the need for its insights was beginning to be apparent to a growing number of leaders in science, politics, and society. It has taken a while for historians to heed Leopold’s advice, but at last the field of environmental history has begun to take shape and its practitioners are trying to build on his initiative. Leopold’s own suggestion of how an ecologically informed history might proceed had to do with the frontier lands of Kentucky, pivotal in the westward movement of the nation. In the period of the revolutionary war it was uncertain who would possess and control those lands: the native Indians, the French or English empires, or the colonial settlers? And then rather quickly the struggle was resolved in favor of the Americans, who brought along their plows and livestock to take possession. It was more than their prowess as fighters, their determination as conquerors, or their virtue in the eyes of God that allowed those agricultural settlers to win the competition; the land itself had something to contribute to their success. Leopold pointed out that growing along the Kentucky bottomlands, the places most accessible to newcomers, were formidable canebrakes, where the canes rose as high as fifteen feet and posed an insuperable barrier to the plow. But fortunately for the Americans, when the cane was burned or grazed out, the magic of bluegrass sprouted in its place. Grass replaced cane in what ecologists call the pattern of secondary ecological succession, which occurs when vegetation is disturbed but the soil is not destroyed, as when a fire sweeps across a prairie or a hurricane levels a forest; succession refers to the fact that a new assortment of species enters and replaces what was there before.

In social learning environments, agents acquire information from both private signals and the observed actions of predecessors, referred to as history. We define the value of history as the gain in expected payoff from accessing both the private signal and history, compared to relying on the signal alone. We first characterize the information structures that maximize this value, showing that it is highest under a mixture of full information and no information. We then apply these insights to a model of markets for history, where a monopolistic data seller collects and sells access to history. In equilibrium, the seller's dynamic pricing becomes the value of history for each agent. This gives the seller incentives to increase the value of history by designing the information structure. The seller optimal information discloses less information than the socially optimal level.

Kukveni—footprints—are a powerful historical metaphor that the Hopi people use to comprehend their tangible heritage. Hopis say that the deity Máasaw instructed their ancestors to leave footprints during their migrations from their origin place to their home today as evidence that they had fulfilled a spiritual pact to serve as stewards of his land. Today’s Hopis understand these footprints to be the archaeological remains of former settlements—pottery sherds, stone tools, petroglyphs, and other physical evidence of past use and occupation of the land. The fourteen chapters in Footprints of Hopi History: Hopihiniwtiput Kukveni’at focus on these Hopi footprints as they are understood through a variety of research techniques, including archaeology, ethnography, documentary history, plant genetics, and educational outreach. The editors and contributors offer fresh and innovative perspectives on Hopi archaeology and history, and demonstrate how one tribe has significantly advanced knowledge about its past through collaboration with archaeologists and cultural anthropologists. The book features managerial uses of research, cultural landscape theory, use of GIS in research, archaeological interpretations of social identity and immigration, analysis of corn genetics, heritage education of youth, and research of oral traditions and documentary history. Footprints of Hopi History highlights the Hopi tribe’s leadership in sustained efforts to create bridges between tribal goals and anthropology, forging a path for others to follow

A formalism is proposed to describe entangled quantum histories, and their entanglement entropy. We define a history vector, living in a tensor space with basis elements corresponding to the allowed histories, i.e. histories with nonvanishing amplitudes. The amplitudes are the components of the history vector, and contain the dynamical information. Probabilities of measurement sequences, and resulting collapse, are given by generalized Born rules: they are all expressed by means of projections and scalar products involving the history vector. Entangled history states are introduced, and a history density matrix is defined in terms of ensembles of history vectors. The corresponding history entropies (and history entanglement entropies for composite systems) are explicitly computed in two examples taken from quantum computation circuits.

Charles Darwin has been moldering in his grave now for a full century. But it is not death with which we associate his name; it is life, in all its abundance and variety. In particular, the argument he made for the natural origin of life, including humans, has been one of the most influential ideas in the world over that century’s span. It was accepted a long while back by almost everyone within the reach of modern science, despite the persistent opposition of a raggle-taggle band of creationists. But for all that general acceptance, Darwin’s ideas have not yet become working principles among several large groups of scholars. Take history, for example: reading the journals and dissertations in this field reveals the profound, continuing influence of Adam Smith, Karl Marx, and Sigmund Freud, but still there is no Darwin in our history, at least not as a tradition of historical theory. Evolution and history remain, after a hundred years, separate realms of discourse. There is little history in the study of nature, and there is little nature in the study of history. I want to show how we can remedy that cultural lag by developing a new perspective on the historian’s enterprise, one that will make us Darwinians at last. It will require us to step back now and then from parliamentary debates, social mobility data, and the biographies of illustrious figures in order to examine more elemental questions that concern the long-running human dialogue with the earth. The contemporary disjunction between the study of history and of nature has a fairly obvious explanation. In the eighteenth-century world of the English parson-naturalist, there was no such split; antiquities and natural curiosities lay jumbled together in the same country cupboard. As we moved away from that small rural community, the old broad-gauged, integrative “natural history” began to fragment into specializations. History increasingly became an archival pursuit, carried on by urban scholars; there was less and less dirt on it. Recently, however, that drift toward an unnatural history has run up against a few hard facts: dwindling energy supplies, population pressures on available food, the limits and costs of technology.

Decoherent histories quantum theory is reformulated with the assumption that there is one "real" fine-grained history, specified in a preferred complete set of sum-over-histories variables. This real history is described by embedding it in an ensemble of comparable imagined fine-grained histories, not unlike the familiar ensemble of statistical mechanics. These histories are assigned extended probabilities, which can sometimes be negative or greater than one. As we will show, this construction implies that the real history is not completely accessible to experimental or other observational discovery. However, sufficiently and appropriately coarse-grained sets of alternative histories have standard probabilities providing information about the real fine-grained history that can be compared with observation. We recover the probabilities of decoherent histories quantum mechanics for sets of histories that are recorded and therefore decohere. Quantum mechanics can be viewed as a classical stochastic theory of histories with extended probabilities and a well-defined notion of reality common to all decoherent sets of alternative coarse-grained histories.

We introduce quantum history states and their mathematical framework, thereby reinterpreting and extending the consistent histories approach to quantum theory. Through thought experiments, we demonstrate that our formalism allows us to analyze a quantum version of history in which we reconstruct the past by observations. In particular, we can pass from measurements to inferences about "what happened" in a way that is sensible and free of paradox. Our framework allows for a richer understanding of the temporal structure of quantum theory, and we construct history states that embody peculiar, non-classical correlations in time.

D. Wallace has tried to use decoherence to solve the preferred basis problem of Everettian Quantum Mechanics, and this solution lays the foundation for his proof of the Born rule. But this is a circular argument, as approximations used in decoherence usually rely on the probabilistic interpretation of the Hilbert space norm. He claims the norm can measure approximations even without probabilities, but this assumption has not been properly justified. Without it, the combination of the Everettian and decoherent histories formalisms leads to strange consequences, such as a proliferation of small amplitude histories with lots of macroscopic quantum jumps. Still, this erratic behavior may provide a way to justify the approximations, in a new histories formalism, in which macroscopic causal relations play a central role. Small histories, suffering too much interference, may lose causality, being thus discarded as invalid. The remaining branches can present some small interference, opening the possibility of experimental verification.
