Detecting the environmental impact of the Baltic Crusades on a late-medieval (13th-15th century) frontier landscape: palynological analysis from Malbork Castle and hinterland, Northern Poland

Palaeoecological analysis of peat deposits from a small bog, combined with pollen analysis of sediments infilling the moat of the nearby Teutonic Order castle at Malbork, have been used to examine the ecological impact of the Crusades on the late-medieval landscape of Northern Poland. Studies of the environmental impact of the Crusades have been almost exclusively informed by written sources; this study is the first of its type to directly investigate the environmental context of Crusading as a force of ecological transformation on the late-medieval Baltic landscape. The pollen evidence from Malbork Castle and its hinterland demonstrate that the 12th/13th–15th centuries coincide with a marked transformation in vegetation and land-use, characterized by clearance of broadleaved woodland and subsequent agricultural intensification, particularly during the 14th/15th centuries. These changes are ascribed to landscape transformations associated with the Teutonic Order’s control of the landscape from the mid-13th century. Human activity identified in the pollen record prior to this is argued to reflect the activities of Pomeranian settlers in the area. This paper also discusses the broader palaeoecological evidence for medieval landscape change across Northern Poland.

Inferring animal husbandry strategies in coastal zones through stable isotope analysis: new evidence from the Flemish coastal plain (Belgium, 1st-15th century AD)

In a proof-of-concept study, Britton et al. (2008) demonstrated that the isotopic composition of halophytic plants can be traced in the skeletal tissues of their animal consumers. Here we apply the method to domestic herbivore remains (n = 303) from nine archaeological sites in or near the Flemish coastal plain (Belgium), where, prior to embankments, salt-marshes offered extensive pasture grounds for domestic herbivores. The sites span a period of ∼1500 years (Roman to late medieval period), during which the coastal landscape was progressively transformed from little managed wetlands to a fully embanked polder area. The bulk collagen data show variations between sites and over time, which are consistent with this historical framework and are interpreted as reflecting environmental change and differences in animal management in the coastal plain throughout the late Holocene. The study demonstrates the immense value of faunal stable isotope analysis for characterising coastal husbandry strategies beyond the means of traditional zooarchaeological techniques.

Translating Lucretia: word, image and 'ethical non-indifference' in Simon de Hesdin's translation of Valerius Maximus's 'Facta et dicta memorabilia'

An analysis of how illustrations functioned as a distinctive and important aspect of the translation of Latin versions of the story of the rape and suicide of Lucretia into Middle French texts, especially the 'Faits et dits memorables' (a translation-adaptation of Valerius Maximus's 'Facta et dicta memorabilia'). The study focuses on a selection of 14th- and 15th- century illuminations, and proposes also that the early modern 'Lucretia' portrait tradition should be viewed in the context of these images.

Season of birth and sheep husbandry in late Roman and Medieval coastal Flanders: a pilot study using tooth enamel d18O analysis

From the early Roman period, there is archaeological evidence for the exploitation of the Flemish coastal plain (Belgium) for a range of activities, such as sheep herding on the then developing salt-marshes and salt-meadows for the production of wool. During the early Middle Ages, this culminated in the establishment of dedicated ‘sheep estates’. This phase of exploitation was followed by extensive drainage and land reclamation measures in the high Medieval period, transforming areas into grassland, suited for cattle breeding. As part of a larger project investigating the onset, intensification and final decline of sheep management in coastal Flanders in the historical period, this pilot study presents the results of sequential sampling and oxygen isotope analysis of a number of sheep teeth (M2, n = 8) from four late Roman and Medieval sites (dating from 4th to 15th century AD), in order to assess potential variations in season of birth between the different sites and through time. In comparison with published data from herds of known birth season, incremental enamel data from the Flemish sites are consistent with late winter/spring births, with the possibility of some instances of slightly earlier parturition. These findings suggest that manipulation of season of birth was not a feature of the sheep husbandry-based economies of early historic Flanders, further evidencing that wool production was the main purpose of contemporary sheep rearing in the region. Manipulation of season of birth is not likely to have afforded economic advantage in wool-centred economies, unlike in some milk- or meat-based regimes.

Accounting as interpretive framing

The study furthers our understanding of the persuasive and constructive aspects of accounting information. We consider it as a process of ‘interpretive framing’ in the quest for legitimacy - an attempt to justify decisions and excuse mistakes. We base our theoretical discussion on the premise that the picture reported by accounting information is an example of institutional reality and thus mediated by the social contexts in which it is constructed and interpreted. Accounting information is a matter of ‘the interpretation of interpretations’ - the provision of accounting information, which is already a result of a competitive interplay among prior interpretations of certain aspects of our economic phenomena, undergoes further interpretation by the recipients of that information. This notion applies equally to narratives and numbers. We challenge notions of rigor, accuracy and objectivity assigned to quantification in accounting and posit that numbers can be an even more powerful rhetorical device due to their image of being rational and ‘rhetoric free’. We illustrate our theoretical propositions presenting explicit references to the constructive and rhetorical aspects of financial reporting from Pacioli and his times (late 15th century) to the recent regulatory developments of FASB/IASB in 2013, i.e. from the rhetoric of double entry book-keeping to the rhetoric of 'fair value’. We acknowledge, building on these theoretical foundations, the inherent subjectivity of accounting information (influenced by perceptions and interests) without entirely denying however its informative functions. We illustrate the practical implications of this, in a situation where “shared and socially accepted” perceptions may be the nearest we can get to anything resembling a faithful representation of economic reality. The paper contributes to a broader understanding of how accounting information can be viewed as a social and humanistic construction, and challenges taken-for-granted assumptions about impartiality, neutrality and rationality in regard to the process.

Architectural enthusiasm: visiting buildings with The Twentieth Century Society

In this paper we put forward the concept of architectural enthusiasm—a collective passion and shared emotional affiliation for buildings and architecture. Through this concept and empirical material based on participation in the architectural tours of The Twentieth Century Society (a UK-based architectural conservation group), we contribute to recent work on the built environment and geographies of architecture in three ways: first, we reinforce the importance of emotion to people’s engagements with buildings, emphasising the shared and practised nature of these engagements; second, we highlight the role of architectural enthusiasts as agents with the potential to shape and transform the built environment; and third, we make connections between (seemingly) disparate engagements with buildings through a continuum of practice incorporating urbex, local history, architectural practice and training, and mass architectural tourism. Unveiling these continuities has important implications for future research into the built environment, highlighting the need to take emotion seriously in all sorts of professional as well as enthusiastic encounters with buildings, and unsettling the categories of amateur and expert within architectural practices.

Rationality of service composition of Workflow Net in a service oriented architecture

Users’ requirements change drives an information system evolution. Consequently, such evolution affects those atomic services which provide functional operations from one state of their composition to another state of composition. A challenging issue associated with such evolution of the state of service composition is to ensure a resultant service composition remaining rational. This paper presents a method of Service Composition Atomic-Operation Set (SCAOS). SCAOS defines 2 classes of atomic operations and 13 kinds of basic service compositions to aid a state change process by using Workflow Net. The workflow net has algorithmic capabilities to compose the required services with rationality and maintain any changes to the services in a different composition also rational. This method can improve the adaptability to the ever changing business requirements of information systems in the dynamic environment.
