Catharine Macaulay's discussion of freedom of the will in her Treatise on the Immutability of Moral Truth has received little attention, and what discussion there is attributes a number of different, incompatible views to her. In this paper the account of the nature of freedom of the will that she develops is related to her political aspirations, and the metaphysical position that she adopts is compared to those of John Locke, Samuel Clarke, Joseph Priestley, William Godwin, and others. It is argued that although Macaulay's position is ultimately ambiguous, she is most plausibly interpreted as following Locke's discussion of free will in his Essay Concerning Human Understanding and of inheriting, from him, the ambiguity that we find in her account.  相似文献

This study provides a unique method of inquiry for archaeological investigation with an aim to assess the intensity and effects of Neolithic and Bronze Age farming practices at Lough Dargan, northwest Ireland, through a multi-proxy analysis of a lake sediment core. Chironomid (non-biting midge fly) subfossils and lake sediment geochemistry (δ13C, δ15N and C:N ratios) were used to assess changes in limnological conditions through time. The limnological data were compared with macroscopic charcoal concentration and pollen data to examine the potential influence that early farmers had on a freshwater lake system within a prehistorically active catchment. Results from the chironomid analysis show that the first substantial period of agricultural activity in the early Neolithic (c. 3730–3190 BC) resulted in a temporary shift to more eutrophic lake conditions. There is evidence of animal husbandry with substantial levels of animal waste reaching the lake, leaving an imprint in the geochemical record of increased δ15N values and decreased δ13C values and C:N ratios during this time. The chironomid community reverted back to its pre-impacted state c. 3190 BC in response to a period of reduced farming (c. 3390–3000 BC) which eventually led to a distinct lull in activity, with possible cessation of farming from 3000 to 2700 BC. A return to eutrophic conditions coincided with the gradual return of agriculture, with more permanently altered lake conditions dominating from 2400 BC, even during a 250-year period of reduced human activity commencing at c. 1440 BC. Increased sedimentation rate, along with increases in δ13C, δ15N and C:N, the presence of chironomid taxa indicative of erosion, more eutrophic lake conditions and high concentrations of macroscopic charcoal all point to more intensive land use practices during the Bronze Age. Palaeolimnological data exhibited an immediate response to intensified farming during this time, and were especially responsive to pastoral farming due either to scale of activity or proximity to the lakeside. The success of this study demonstrates the effectiveness of palaeolimnological analysis in the investigation of prehistoric farming. This approach will help inform Neolithic and Bronze Age land-use practice and human–environment relations in the region, and highlights the potential for chironomid-based archaeological research.  相似文献

Abstract

Geological information was first printed in colour on a map in 1820 but serious efforts to print geological maps in multiple colours began in Europe only in the 1840s. Increased geological mapping activity created the need to print more maps by cheaper methods, while general advances in lithographic colour printing provided the means. Better colour registration, transparency, range, permanence and distinctiveness were attained in the 1840s and 1850s by technical innovations and also by new design strategies. Consequently, as printed colour replaced hand colour as the norm, it also influenced the look of the geological map.  相似文献

ABSTRACT

Following the theorisation of museums as agonistic spaces and drawing on a comparative analysis of war museums located in various European countries, this paper argues that these institutions play complex and multi-layered roles beyond their obvious educational function. These not easily reconcilable roles act as major constraints upon the form and content of exhibitions and work against the adoption of an agonistic approach. However, the paper also argues that war museums are especially apt to become sites of political contestation able to engage with agonistic memory and unsettling counter-narratives. This is due in large part to the nature of the subject matter they deal with, as war and conflict lend themselves to being represented in ways that emphasise patriotic consensus but can also highlight dissent, contestation, multiple perspectives and alternative visions of society. Agonistic practices emerge when windows of opportunity open through a combination of top-down and bottom-up agency able to take advantage of particular socio-political circumstances or cultural developments. The paper also discusses a new exhibition on war memory planned for late 2018 in Essen, Germany and conceived as a strategic political intervention, which aims to communicate in an agonistic fashion with its audiences.  相似文献

Abstract

Transylvania, situated beneath the Carpathian mountains, is one of the travel frontiers of Europe and the most romantic province of Romania. To most of its visitors, Transylvania is associated with haunted castles and vampires, thanks to the literary character Dracula. Even though Bran Castle appears to form the perfect home for a vampire count, this heritage destination is surrounded by debate because of the conflicting marketing strategies adopted by various organisations for the specific purpose of increasing the profits made from tourism. This paper explores issues of marketing, policies for interpretation and the understanding of heritage sites within a formerly socialist society in transition to a market economy. It analyses potential promotional, advertising and interpretive strategies which could be applied to Bran Castle, and offers solutions to produce a better understanding of the role of heritage tourism in a transitional economy.  相似文献

Paying for water: water pricing and equity in England and Wales   总被引:2,自引:0,他引:2  
Over the past three decades, the business of water supply in England and Wales has been gradually transforming from the supply of a service to citizens, to the sale of a commodity to customers. The paper provides a genealogy of concepts of efficiency and equity in water regulation over the past thirty years, prior to evaluating the implications for water consumers of one aspect of this process – the shift away from policies prioritizing inter- and intra-regional equalization (implying a principle of social equity) towards policies prioritizing economic efficiency (implying a principle of economic equity) in water charging. In closing, alternatives to the current arrangements for domestic consumers are proposed.  相似文献
