Organic Geochemical Evidence for Pine Tar Production in Middle Eastern Sweden During the Roman Iron Age

Several funnel-shaped features of unknown function were discovered at excavations related to a new stretch of the highway E4 in middle Sweden during 2002–2003. These features could be sub classed into two categories: large funnel-shaped pits dated to 600–1100 AD (Vendel period – Viking Age) and small funnel-shaped pits dated to 240–540 AD (late Roman Iron Age – Migration period) respectively. Soil samples were analysed for diterpenoids derived from abietic acid (mainly retene, abietic acid, dehydroabietic acid and methyl dehydroabietate) by Gas Chromatography-Mass Spectrometry (GC-MS) in order to test the hypothesis that the features might be connected to pine tar manufacture. For comparison, samples from historically known pine tar and charcoal production features were analysed. The resinous fraction in the larger funnel-shaped features were very similar to those of the historical pine tar and charcoal production features, while the composition in the small funnel-shaped pits was dominated by retene and methyl dehydroabietate. The biomarker, methyl dehydroabietate, could be identified in several of the soil samples from the funnel-shaped pits. We suggest that both of these features have been used for pine tar production, which makes the smaller funnel-shaped features the oldest known tar production features in Europe.     

A real options approach to amenity valuation: The role of uncertainty and risk aversion

Many empirical studies in the fields of urban and environmental economics rely on the hedonic pricing framework. This paper draws attention to two important elements that are not covered by this theory: uncertainty and relocation costs. It develops a theoretical model where agents face uncertainty, but may accumulate savings as a form of self‐insurance. It shows that uncertainty pushes up relocation costs due to the option value of waiting, while self‐insurance helps to reduce this lock‐in problem. Moreover, the model suggests that the implicit price of environmental quality increases with uncertainty even if agents are risk‐neutral.     

Design als ‘mediating interface’ Zur Zeugen‐ und Zeichenhaftigkeit des Radioapparates

Design as Mediating Interface: Historical Evidence and Symbolic Enunciation of the Radio Set. – Based on a case study on the invention of the radio station scale in the late 1920's and early 1930's, this article pleads for an interdisciplinary look at the importance of design as a mediating interface in the production‐consumption junction. In this cultural history perspective on technology, the material artifact matters both as a witness of and a sign for the symbolic meaning and appropriation of the technical object, which transgresses the functional logic of instrumental rationality. In presenting five different perspectives on design offering some alternative looks for a cultural history of technology, this theoretically inspired essay wants to sound the critical potential of a multilayered semantic approach to the radio apparatus as a prominent representation of a radical innovation in media technology.     

Cooperative Housing and Social Cohesion: The Role of Linking Social Capital

Abstract

The article examines the role of housing cooperatives for social cohesion in the city by introducing linking social capital which grasps the vertical dimension of social capital. Housing cooperatives represent a crucial intermediate level between residents and urban housing policy, thus providing opportunity structures for bottom-linked citizen participation. Drawing on the case of Vienna, a large-scale household survey and interviews with key informants provide empirical evidence on the importance of a form of social capital which links actors at different levels in the spatial hierarchy: residents, housing managers and political decision-makers. The findings add to our understanding of the opportunities and problems with resident participation in a policy field structured by multi-level governance. Our two-level analysis shows that the dominant model of governance, top-down as well as neoliberal, has structurally limited the room for participatory practices in cooperative housing. Nevertheless, we argue that professional housing cooperatives have a potential to give residents a voice beyond the neighbourhood. Their strong linkages with public decision-makers at different scales can help leverage ideas and resources of residents.     

Deliberation in representative institutions: an analytical framework for a systemic approach

This article presents a novel analytical account of the relationship between deliberation and representation by reconstructing the specific institutional logics that guide deliberative action in parliaments. In contrast to the dominant generalised paradigm in empirical deliberation research it develops a contextualised-systemic approach. The article argues that the parliamentary context is characterised by a tension between two equally legitimate institutional logics: a discursive one, institutionalised through parliamentary procedures, and a positional one, constituted by relations of representation. The resulting theoretical model links the specific institutional and situational conditions to different forms and functions of deliberation. Depending on the specific balance between both logics deliberation fulfils functions of either integration or contestation. The model is applied to a comparative analysis of different cases of parliaments demonstrating how this account can advance both the comparative analysis of deliberation in representative institutions and the development of deliberative democracy after the systemic turn.     

Common usage,presumption and verisimilitude in sixteenth-century theories of juridical interpretation

The question of how common usage could be constitutive for the meaning of linguistic expressions has been discussed by Renaissance philosophers such as Lorenzo Valla, and it also played an important role in Renaissance theories of juridical interpretation. An aspect of the analysis of common usage in Renaissance theories of juridical interpretation that concerns the role of presumption has not yet found much attention. Renaissance jurists such as Simone de Praetis, Nicolaus Everardus, and Aimone de Cravetta saw that both the usage of Latin by practitioners of law and the vernacular common usage of ordinary people often differed from the technical definition of legal concepts as laid down by ancient jurists or modern legislators. In some cases, they ascribed both to Latin and to vernacular common usage the power of changing the meaning of juridical terms. Still, they were aware of the fact that matters of common usage involve always a degree of uncertainty. The methodological notion of presumption is one of the concepts that figured most prominently in Renaissance approaches to the problem of uncertainty, and, in particular, it was applied in the analysis of meaning-change of legal concepts through common usage.     

Esse servitutis omnis impatientem/Man is impatient of all servitude: Human Dignity as a Path to Modernity in Ficino and Pico della Mirandola?

Abstract

The notion of human dignity stands at the core of contemporary debates on rights, politics, and ethics. Many scholars consider the Renaissance discourse on dignity as one of its main contributions to the transition from the Middle Ages to modernity. This article examines the role of human dignity in the philosophies of Marsilio Ficino and Giovanni Pico della Mirandola. In their works human dignity relates both to freedom and to a Neo-Platonic ontology, which raises the question of how they reconcile these two possibly contradictory elements. I show that starting from the insight that human beings are “naturally” free and able to make right choices, Ficino and Pico argue that human dignity consists in the ability of humans to understand what is good and to act accordingly. I thus defend the thesis that their conception of human dignity is not modern because it liberates human beings from the “history of being” but rather because it paves the way for their liberation to become rational beings.     

From Byzantine to post-Byzantine art: the painting technique of St Stephen's wall paintings at Meteora,Greece

The old katholikon of St Stephen's monastery at the Meteora (site of the most important complex of monasteries in Greece after Mount Athos) is decorated with wall paintings that date from the beginning of 17th century. In terms of style, the artistic ensemble is altogether characteristic of the period. The painting technique has been examined by means of μRaman and μFTIR spectroscopies, gas chromatography–mass spectroscopy (GC/MS), optical microscopy (OM) and scanning electron microscopy (SEM).
