As a preliminary phase in the conservation and sustainable management of a karst system in Fuentetoba, Soria, Spain, an interdisciplinary study was carried out to determine its hydrogeological evolution. The hydrogeological history of this aquifer system began during the late Miocene, where discharges were driven by paleo-emergences in the moor, and associated conduits were developed under phreatic (or vadose) conditions—for example, the upper syngenetic galleries in the main known karst cave (Majada del Cura cave). Later on, the nearby karstic massifs, a general flattening of the relief, occurred during the Quaternary Period, during which the karstic base level had been in decline. The aquifer flow was then derived and modified towards the Fuentetoba spring from the earliest stages through the galleries of the aforementioned cave. The observations made in this cave indicate the existence of a unique type of hydrogeological organization. The hypogean network is the result of the excavation of the same water flow that has been entrenching and abandoning the vadose regimen toward the free regimen. The dating of the tuffaceous buildings, associated with the emergences, indicates that since almost the Middle Pleistocene, flow lines have converged in the Fuentetoba spring, inducing a high grade of karstification in the saturated zone of the syncline basin. Moreover, a major drainage conduit was developed by dissolution. During the late Upper Pleistocene, an essential component of the groundwater flow had been derived towards the source of the Mazos River spring. Tufa and paleogour datings in caves indicate that the aquifer has undergone different climatic stages during the latest Quaternary and, therefore, different feeding and recharge processes. These tufas and paleogours are interrelated as well, as they are associated with the warm stages during the most recent Quaternary, according to the regional context, when there was less natural recharge. The simulation of the springs’ flow enabled an approximate quantification of the variation in the aquifer’s hydraulic balance during the different climatic stages. For example, during the last glaciation, the natural recharge was impacted by snowmelt and increased by 160%.

<p>Multi-level cave systems record the history of regional river incision in abandoned alluvium-filled phreatic passages which, mimicking fluvial terrace sequences, represent former phases of fluvial base-level stability. In this respect, cosmogenic burial dating of in cave-deposited alluvium (usually via the nuclide pair <sup>26</sup>Al/<sup>10</sup>Be) represents a suitable method to quantify the pace of long-term river incision. Here, we present a dataset of fifteen <sup>26</sup>Al/<sup>10</sup>Be burial ages measured in fluvial pebbles washed into a multi-level cave system developed in Devonian limestone of the uplifted Ardenne massif (eastern Belgium). The large and well-documented Chawresse system is located along the lower Ourthe valley (i.e. the main Ardennian tributary of the Meuse river) and spans altogether an elevation difference exceeding 120 m.</p><p>The depleted <sup>26</sup>Al/<sup>10</sup>Be ratios measured in four individual caves show two main outcomes. Firstly, computed burial ages ranging from ~0.2 to 3.3 Ma allows highlighting an acceleration by almost one order of magnitude of the incision rates during the first half of the Middle Pleistocene (from ~25 to ~160 m/Ma). Secondly, according to the relative elevation above the present-day floodplain of the sampled material in the Manants cave (<35 m), the four internally-consistent Early Pleistocene burial ages highlight an “anomalous” old speleogenesis in the framework of a gradual base-level lowering. They instead point to intra-karsting reworking of the sampled material in the topographically complex Manants cave. This in turn suggests an independent, long-lasting speleogenetic evolution of this specific cave, which differs from the <em>per descensum</em> model of speleogenesis generally acknowledged for the regional multi-level cave systems and their abandoned phreatic galleries. In addition to its classical use for inferring long-term incision rates, cosmogenic burial dating can thus contribute to better understand specific and complex speleogenetic evolution.</p>

Abstract The appearance of monodactyl equids in Eurasia and their dispersal towards South Europe is a significant event that marks the beginning of the Quaternary period. During the Pleistocene, horses were a common element in most European large mammal faunal assemblages, providing important palaeoecological clues, but their taxonomy, nomenclature and phylogeny, as well as their actual biochronological significance have been widely debated by scholars. The evolutionary history of horses here regarded as “stenonoid” (Equus livenzovensis, Equus stenonis, Equus ex gr. E. senezensis, Equus altidens, Equus hydruntinus, the large-sized horses Equus major and Equus suessenbornensis, sometimes referred to as the so-called “Equus bressanus-Equus suessenbornensis group”), is one of the most intriguing. This study, mainly focusing on the South European representatives of this group, aims to highlight and discuss the major debated issues, re-examining the taxonomy of some Early and early Middle Pleistocene horses. Alternative phylogenetic hypotheses will also be discussed with the aim of providing new clues on the chronology and palaeoecology of some key species/samples.

The review considers the first attempt in the history of Russian economic thought to give a detailed analysis of informal institutions (IF). It recognizes that in general it was successful: the reader gets acquainted with the original classification of institutions (including informal ones) and their genesis. According to the reviewer the best achievement of the author is his interdisciplinary approach to the study of problems and, moreover, his bias on the achievements of social psychology because the model of human behavior in the economic mainstream is rather primitive. The book makes evident that namely this model limits the ability of economists to analyze IF. The reviewer also shares the author’s position that in the analysis of the IF genesis the economists should highlight the uncertainty and reject economic determinism. Further discussion of IF is hardly possible without referring to this book.

Sergey Esenin’s tragic end is widely known and provokes disputes to this day. The official reports put it down as a suicide. The incident could be analyzed more effectively by means of an interdisciplinary approach using the latest forensic know-how. The documented circumstances of Esenin’s death, found in recorded testimonies and interviews, as well as the materials of the Russian National Esenin Committee of Writers, are examined through the author’s own classification of forensically relevant evidence of suicide. The analysis reveals that suicide remains the most probable version. Far from solving this incident for good, these conclusions may become an important forensic contribution to the history of Russian culture.

The types of geological and geomorphological structure of the Katun valley are distinguished in the work. For this, a method of geoinformation mapping using morphometric indicators of the valley’s width and meandering of the channel was developed. The morphometric parameter of the valley’s width was calculated as the total area of terraces. As the morphometric parameters of the channel’s meandering, the angles of the river segments’ deviation relative to each other were calculated. Conjugated analysis of these morphometric indicators enabled identifying 18 morphotypes. These morphotypes according to the geological and geomorphological structure of the valley were combined into 4 classes. Separation of the Katun valley in certain classes and morphotypes is due to the different geological history of these sites during the Quaternary period. The most important reasons predetermining the modern variety of geological and geomorphological types of the valley are neotectonic movements and exogenous phenomena (glaciers, dam lakes, landslides, etc.) naturally localized in the space from the upstream of the river to its exit into the foothills. The developed method can be applied for quantitative morphometric classification of the mountain rivers’ valleys in other regions.

Tabernae were ubiquitous among all Roman cities, lining the busiest streets and dominating their most crowded intersections, and in numbers not known by any other form of building. That they played a vital role in the operation of the city—indeed in the very definition of urbanization—is a point too often under-appreciated in Roman studies, or at best assumed. The Roman Retail Revolution is a thorough investigation into the social and economic worlds of the Roman shop. With a focus on food and drink outlets, and with a critical analysis of both archaeological material and textual sources, Ellis challenges many of the conventional ideas about the place of retailing in the Roman city. A new framework is forwarded, for example, to understand the motivations behind urban investment in tabernae. Their historical development is also unraveled to identify three major waves—or, revolutions—in the shaping of retail landscapes. Two new bodies of evidence underpin the volume. The first is generated from the University of Cincinnati’s recent archaeological excavations into a Pompeian neighborhood of close to twenty shop-fronts. The second comes from a field survey of the retail landscapes of more than a hundred cities from across the Roman world. The richness of this information, combined with an interdisciplinary approach to the lives of the Roman sub-elite, results in a refreshingly original look at the history of retailing and urbanism in the Roman world.

How did authors control the literary fates of fictional characters before the existence of copyright? Could a second author do anything with another author’s character? Situated between the decline of the privilege system and the rise of copyright, literary borrowing in eighteenth-century Germany has long been considered unregulated. This book tells a different story. Characters before Copyright documents the surprisingly widespread eighteenth-century practice of writing fan fiction—literary works written by readers who appropriate preexisting characters invented by other authors—and reconstructs the contemporaneous debate about the literary phenomenon. Like fan fiction today, these texts took the form of sequels, prequels, and spinoffs. Analyzing the evolving reading, writing, and consumer habits of late-eighteenth-century Germany, Characters before Copyright identifies the social, economic, and aesthetic changes that fostered the rapid rise of fan fiction after 1750. Based on archival work and an ethnographic approach borrowed from legal anthropology, this book then uncovers the unwritten customary norms that governed the production of these works. Characters before Copyright thus reinterprets the eighteenth-century “literary commons,” arguing that what may appear to have been the free circulation of characters was actually circumscribed by an exacting set of rules and conditions. These norms translated into a unique type of literature that gave rise to remarkable forms of collaborative authorship and originality. Characters before Copyright provides a new perspective on the eighteenth-century book trade and the rise of intellectual property, reevaluating the concept of literary property, the history of moral rights, and the tradition of free culture.

AbstractUsing marine planation surfaces, fluvial terraces and a digital terrain model, the amount of eroded rock volume versus time for the Meuse catchment has been computed. A comparison of the amount of eroded volume with the volume of sediment preserved in the Roer Valley Rift System shows that 12% of the eroded volume is trapped in this rift. The neotectonic uplift evolution of the Ardennes is inferred from the incision history of the Meuse River system and compared to the subsidence characteristics of the Roer Valley Rift System. Both areas are characterized by an early Middle Pleistocene uplift event.

This article aims to encourage the interdisciplinary study of ‘languaculture,’ an approach to language and culture in which ideology, linguistic and cultural forms, as well as praxis are studied in relation to one another. An integrated analysis of the selection of linguistic and cultural elements provides insight into how these choices arise from internalized norms and values, and how people position themselves toward received categories and hegemonic ideologies. An interdisciplinary approach will stimulate a rethinking of established concepts and methods of research. It will also lead to a mutual strengthening of linguistic, sociolinguistic, and anthropological research. This contribution focuses on Limburg and the linguistic political context of this Southern-Netherlands region where people are strongly aware of their linguistic distinctiveness. The argument of the paper is based on a case study of languaculture, viz. the carnivalesque song ‘Naar Talia’ (To Italy) by the Getske Boys from the city of Heerlen.

The ancient glass industry changed dramatically towards the end of the first millennium. The Roman glassmaking tradition of mineral soda glass was increasingly supplanted by the use of plant ash as the main fluxing agent at the turn of the ninth century CE. Defining primary production groups of plant ash glass has been a challenge due to the high variability of raw materials and the smaller scale of production. Islamic Glass in the Making advocates a large-scale archaeometric approach to the history of Islamic glassmaking to trace the developments in the production, trade and consumption of vitreous materials between the eighth and twelfth centuries and to separate the norm from the exception. It proposes compositional discriminants to distinguish regional production groups, and provides insights into the organisation of the glass industry and commerce during the early Islamic period. The interdisciplinary approach leads to a holistic understanding of the development of Islamic glass; assemblages from the early Islamic period in Mesopotamia, Central Asia, Egypt, Greater Syria and Iberia are evaluated, and placed in the larger geopolitical context. In doing so, this book fills a gap in the present literature and advances a large-scale approach to the history of Islamic glass.
