AbstractLOOM (landslide object-oriented model) is here presented as a data structure for landslide inventories based on the object-oriented paradigm. It aims at the effective storage, in a single dataset, of the complex spatial and temporal relations between landslides recorded and mapped in an area and at their manipulation. Spatial relations are handled through a hierarchical classification based on topological rules and two levels of aggregation are defined: (i) landslide complexes, grouping spatially connected landslides of the same type, and (ii) landslide systems, merging landslides of any type sharing a spatial connection. For the aggregation procedure, a minimal functional interaction between landslide objects has been defined as a spatial overlap between objects. Temporal characterization of landslides is achieved by assigning to each object an exact date or a time range for its occurrence, integrating both the time frame and the event-based approaches. The sum of spatial integrity and temporal characterization ensures the storage of vertical relations between landslides, so that the superimposition of events can be easily retrieved querying the temporal dataset. The here proposed methodology for landslides inventorying has been tested on selected case studies in the Cilento UNESCO Global Geopark (Italy). We demonstrate that the proposed LOOM model avoids data fragmentation or redundancy and topological inconsistency between the digital data and the real-world features. This application revealed to be powerful for the reconstruction of the gravity-induced deformation history of hillslopes, thus for the prediction of their evolution.

Which kind of relation exists between a stone, a cloud, a dog, and a human? Is nature made of distinct domains and layers or does it form a vast unity from which all beings emerge? Refusing at once a reductionist, physicalist approach as well as a vitalistic one, Whitehead affirms that « everything is a society » This chapter consequently questions the status of different domains which together compose nature by employing the concept of society. The first part traces the history of this notion notably with reference to the two thinkers fundamental to Whitehead: Leibniz and Locke; the second part defines the temporal and spatial relations of societies; and the third explores the differences between physical, biological, and psychical forms of existence as well as their respective ways of relating to environments. The chapter thus tackles the status of nature and its domains.

Different Sources

Medieval Scottish economic and social history has held little interest for a unionist establishment but, just when a recovery of historic independence begins to seem possible, this paper tackles a (perhaps the) key pre-1424 source. It is compared with a Rutland text, in a context of foreign history, both English and continental. The Berwickshire text is not, as was suggested in 2014, a ‘compte rendu’ but rather an ‘extent’, intended to cross-check such accounts. Read alongside the Rutland roll, it is not even a single ‘compte’ but rather a palimpsest of different sources and times: a possibility beyond earlier editorial imaginings. With content falling (largely) within the time-frame of the PoMS project (although not actually included), when the economic history of Scotland in Europe is properly explored, the sources discussed here will be key and will offer an interesting challenge to interpretation. And some surprises about their nature and date.

Part I of this book is an in-depth examination of the characteristics of the Tuscan aristocracy across the first two and a half centuries of the second millennium, as studied by Italian historians and others working within the Italian tradition: their origins, interests, strategies for survival and exercise of power; the structure and the several levels of aristocracy and how these interrelated; the internal dynamics and perceptions that governed aristocratic life; and the relationship to non-aristocratic sectors of society. It will look at how aristocratic society changed across this period and how far changes were internally generated as opposed to responses from external stimuli. The relationship between the aristocracy and public authority will also be examined. Part II of the book deals with England. The aim here is not a comparative study but to bring insights drawn from Tuscan history and Tuscan historiography into play in understanding the evolution of English society from around the year 1000 to around 1250. This part of the book draws on the breadth of English historiography but is also guided by the Italian experience. The book challenges the interpretative framework within which much English history of this period tends to be written—that is to say the grand narrative which revolves around Magna Carta and English exceptionalism—and seeks to avoid dangers of teleology, of idealism, and of essentialism. By offering a study of the aristocracy across a wide time-frame and with themes drawn from Italian historiography, I hope to obviate these tendencies and to appreciate the aristocracy firmly within its own contexts.

Since first observed in 2003, peach skin streaking (PSS) has increasingly affected fruit production in the Southeast. Since 2017 we have documented the occurrence of peach skin streaking on 21 cultivars in South Carolina and symptoms have also been reported in Maryland and Pennsylvania. PSS seems to be linked to an unidentified causal agent mediated in rainwater with susceptibility closely related to the ripening status of maturing fruit. Over the course of the 2019 peach growing season, we collected rainwater at a South Carolina peach farm with a history of PSS and analyzed samples for chemical and physical property. Five cultivars were monitored for occurrence of PSS to associate specific rain events with symptom development in the field. PSS was observed in the field on one of the monitored and three additional cultivars between May and June, and five rain events coincided in time with symptom development. However, chemical, and physical properties from these rainwater samples were not significantly different from samples not associated with PSS in that time frame. Fruit of the five cultivars were also collected at 21, 14, 7 and 0 days before harvest, to determine light absorbance parameters, ΔA and color space, and to induce symptoms under laboratory conditions by treatment with ClO2. There were significant correlations between symptom development and light absorbance parameters illustrating how proneness to PSS increases during fruit maturation.

Frequent public uproar over forms of data science that rely on information about people demonstrates the challenges of defining and demonstrating trustworthy digital data research practices. This paper reviews problems of trustworthiness in what we term pervasive data research: scholarship that relies on the rich information generated about people through digital interaction. We highlight the entwined problems of participant unawareness of such research and the relationship of pervasive data research to corporate datafication and surveillance. We suggest a way forward by drawing from the history of a different methodological approach in which researchers have struggled with trustworthy practice: ethnography. To grapple with the colonial legacy of their methods, ethnographers have developed analytic lenses and researcher practices that foreground relations of awareness and power. These lenses are inspiring but also challenging for pervasive data research, given the flattening of contexts inherent in digital data collection. We propose ways that pervasive data researchers can incorporate reflection on awareness and power within their research to support the development of trustworthy data science.

Comparative studies of large phylogenies of living and extinct groups have shown that most biodiversity arises from a small number of highly species-rich clades. To understand biodiversity, it is important to examine the history of these clades on geological time scales. This is part of a distinct ‘phylogenetic expansion’ view of macroevolution, and contrasts with the alternative, non-phylogenetic ‘equilibrium’ approach to the history of biodiversity. The latter viewpoint focuses on density-dependent models in which all life is described by a single global-scale model, and a case is made here that this approach may be less successful at representing the shape of the evolution of life than the phylogenetic expansion approach. The terrestrial fossil record is patchy, but is adequate for coarse-scale studies of groups such as vertebrates that possess fossilizable hard parts. New methods in phylogenetic analysis, morphometrics and the study of exceptional biotas allow new approaches. Models for diversity regulation through time range from the entirely biotic to the entirely physical, with many intermediates. Tetrapod diversity has risen as a result of the expansion of ecospace, rather than niche subdivision or regional-scale endemicity resulting from continental break-up. Tetrapod communities on land have been remarkably stable and have changed only when there was a revolution in floras (such as the demise of the Carboniferous coal forests, or the Cretaceous radiation of angiosperms) or following particularly severe mass extinction events, such as that at the end of the Permian.

Purpose This paper aims to relate early history of housing conceptualizations and market analysis in the Anglosphere (Britain, the USA, Canada, Australia and New Zealand). Historians are ignorant of them but clear market analyses had early beginnings in every urban society for developing and accommodating growing populations. Design/methodology/approach Historiography. Findings Aspects of market analysis, especially appraisal and rudimentary approaches to the housing market in the Anglosphere, can be traced back to ancient Rome, housing market conceptualizations to Dr Nicholas Barbon and seventeenth-century London’s first population and housing boom and market analysis techniques in the USA at its founding, when Charles-Maurice de Talleyrand Perigor was the first to refine them and write them up in 1794-1796. The US next made major advances in the 1930s. The overall trend has been from inferred analyses to fundamental (derived) analyses, emphasizing “quantifiable data.” Practical implications This paper elicits researcher’s professional awareness that each nation has an implicit history of its early development practices and techniques. Originality/value The time frame of most housing market analysts is the recent past, the present and the future. But how enduring are their concerns? Do operational values in a housing market reflect historical epochs, or are there some universalities? Furthermore, most urban historians are ignorant of urban market dynamics. It does not occur to them that some of the dynamics that analysts attempt to capture today might always have been inherent in the urban built environment, regardless of era or urbanized part of the globe under consideration.

An enduring problem in the assembly of Laurentia is uncertainty about the nature and timing of magmatism, deformation, and metamorphism in the Paleoproterozoic Wisconsin magmatic terranes, which have been variously interpreted as an intra-oceanic arc, foredeep or continental back-arc. Resolving these competing models is difficult due in part to a lack of a robust time-frame for magmatism in the terranes. The northeast part of the terranes in northern Wisconsin (USA) comprise mafic and felsic volcanic rocks and syn-volcanic granites thought to have been emplaced and metamorphosed during the 1890−1830 Ma Penokean orogeny. New in situ U-Pb geochronology of igneous zircon from the volcanic rocks (Beecher Formation), and from two tonalitic plutons (the Dunbar Gneiss and Newingham Tonalite) intruding the volcanic rocks, yielded crystallization ages ranging from 1847 ± 10 Ma to 1842 ± 7 Ma (95% confidence). Thus, these rocks record a magmatic episode that is synchronous with bimodal volcanism in the Wausau domain and Marshfield terrane farther south. Our results, integrated with published data into a time-space diagram, highlight two bimodal magmatic cycles, the first at 1890−1860 Ma and the second at 1845−1830 Ma, developed on extended crust of the Superior Craton. The magmatic episodes are broadly synchronous with volcanogenic massive sulfide mineralization and deposition of Lake Superior banded iron formations. Our data and interpretation are consistent with the Penokean orogeny marking west Pacific-style accretionary orogenesis involving lithospheric extension of the continental margin, punctuated by transient crustal shortening that was accommodated by folding and thrusting of the arc-back-arc system. The model explains the shared magmatic history of the Pembine-Wausau and Marshfield terranes. Our study also reveals an overprinting metamorphic event recorded by reset zircon and new monazite growth dated at 1775 ± 10 Ma suggesting that the main metamorphic event in the terranes is related to the Yavapai-interval accretion rather than the Penokean orogeny.

The concept of strategy was born in military campaigns whose results, whether good or bad, were largely the product of the minds of strategists. From ancient times, much has been said about great military commanders and their strategies. The word strategic comes from the Greek stratego, which literally means general. In the classic division of war into operational, tactical, and strategic aspects, strategy is linked to planning, to the broader environment and the longest time frame. Even though its meaning has changed over time, since the Napoleonic wars it has encompassed military, political and economic dimensions.

In this first essay, we delve into significant moments in the history (and pre-history) of twentieth century Afro-Americanophilia in Germany. We establish a periodisation stretching from the nineteenth century until the mid-1960s (from which point our second essay will continue), and take in the pre-colonial, the colonial, the Weimar, the Nazi; and the post-war eras.  We draw out some of the particularly significant moments, ruptures, and continuities within that time frame. We also identify some of the salient ways scholars have interpreted ‘Afro-Americanophilia’ during the period.  Focusing on a variety of practices of appropriation, communicative media, actors and forms of agency, power differentials, and sociocultural contexts, we discuss positive images of and affirmative approaches to black people in German culture and in its imaginaries. We attend to who was active in Afro-Americanophilia, in what ways, and what the effects of that agency were. Our main focus is on white German Afro-Americanophiles, but—without attempting to write a history of African Americans, black people in Germany, or Black Germans— we also inquire into the ways that the latter reacted to, suffered under the expectations levied upon them, or were able to engage with the demand for ‘black cultural traffic.’
