During the summer of 2008 archaeological excavations and geophysical prospection surveys were carried out in the mountain tundra region of north-eastern Sweden. The investigations focused on locating settlement remains connected with a Middle Neolithic tool production site discovered by archaeologists in 2001.  相似文献

Sadler, T., Kroh, A. &; Gallagher, S.J., March 2016. A review of the taxonomy and systematics of the echinoid genus Monostychia Laube, 1869 Laube, G.C., 1869. Über einige fossile Echiniden von den Murray Cliffs in Süd-Australien. Sitzungsberichte der Kaiserlichen Akademie der Wissenschaften zu Wien, mathematisch-naturwissenschaftliche Classe. Abtheilung I 59, 183198. [Google Scholar]. Alcheringa 40, xxx–xxx. ISSN 0311-5518

A review of Monostychia, a stratigraphically important clypeasteroid echinoid genus in southern Australian Oligocene/Miocene strata, reveals uncertainty in relation to morphological features used in taxonomy. The result is that the exact systematic position of the genus remains unresolved at subfamily level. Monostychia and its type species, M. australis, are redescribed. Monostychia australis is restricted to the lower to middle Miocene Glenforslan Formation of the Murray Basin. Three other species currently within Monostychia, M. etheridgei, M. loveni and M. elongata, are discussed. Although it is concluded that M. etheridgei belongs in the genus and is a distinct species, the taxonomic position of M. loveni is questioned, and the validity of M. elongata as a separate species from M. australis remains uncertain. This work lays the foundation for further revisions of Monostychia with an expectation that such work will provide the basis for character determination that may be useful across other echinoid taxa.

Green areas are of high importance for the population in Germany. This is demonstrated by the representative outcomes of the latest Awareness-of-Nature survey for 2015. Most interviewees do not only value urban greens as personally important but also state that they perceive them as crucial for society and environment. The article focuses especially on the perception by people from different age groups and levels of education. It highlights that the strong awareness of the population provides a good fundament for the objectives and strategies of social, environmental and nature conservation policies.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献
