In 1665, Robert Hooke published his major work in microscopy, Micrographia, a defense of experimental philosophy. The following year, Margaret Cavendish, Duchess of Newcastle, published at her own expense a treatise and a novel that undermined the basis of this new science. The dispute broke out at the initiative of the Duchess, in the context of a vast controversy about the legitimacy and the efficiency of optical instruments in natural philosophy. All the figures of the dual are used, except one: the counterattack. Cavendish, indeed, was alone on the battlefield. Is it possible to call a dual a battle with only one combatant? This particular case of dispute that stops owing to the shortage of combatants is the subject of this article.  相似文献

Companies' community involvement turns out to be spatially relevant and–in many cases–to be focused on the near surroundings of the place of business. Some companies strategically align their involvement in order to systematically address local challenges. The essay at hand addresses the subject of corporate social responsibility from a local development perspective. Using the example of two family-owned enterprises based in Duisburg, Haniel and Grillo, it illustrates how socially committed companies can get involved with their local community by acting as good neighbours. Furthermore, it argues that socially committed companies can function as producers of space concerning matters of urban and local development. The specific local settings as well as the economic conditions of the local community serve as an explanatory background of the companies' involvement. The cases presented in this paper prove the firms' specific knowledge of local development needs and possibilities. This makes them qualified partners for local government actors and civil society actors. Thus, in the future, it is worth addressing corporate local responsibility from a governance point of view both in theory and in practice.  相似文献

Urban green space is a key subject of actual urban negotiation processes on how the city shall develop. Visions of the ideal city are reflected in the meanings currently ascribed to urban gardening. Thereby the relation between human and nature as well as between build and natural environment in the city plays a central role. Results from different Swiss cities show that allotment gardens as well as newer forms of urban gardening are oscillating between a compensatory and a complementary understanding of nature, and they equally combine the desire for pristine nature with the demand for functional green space in the city.  相似文献

Mapungubwe (AD 1220–1290) is generally regarded as the first urban centre in southern Africa, functioning as the seat of power for an extensive but short-lived polity. More than 80 years of excavations here, and at its nearby predecessor K2 (c. AD 1000–1220), resulted in a substantial assemblage of material remains from elite and commoner contexts. This assemblage includes a large collection of worked bone objects, such as needles, awls, tubes and objects of personal adornment. Of particular interest are the bone arrowheads and link-shafts, of which a significant number of specimens were found complete and intact. Such quantities of well-preserved worked bone objects are unique in the archaeological record of the region. The worked bone assemblages from these two sites provide a rare opportunity to study multiple components of the production process as well as the use context of bone objects. In this paper, we characterise the K2 and Mapungubwe worked bone industries through various morphological, technological, use-trace and contextual approaches and discuss the significance of these aspects in terms of raw material selection and manufacture and archaeological use context. In particular, this study shows the complexity of these worked bone industries over time.  相似文献

Located in northeastern South Africa in the Kruger National Park, the wild-dominated faunal assemblages at Le6 and Le7 allow for a site-level examination of the treatment of wild species within the highly variable spectra of Early Iron Age animal use. Looking at hunting beyond pure subsistence choices, this paper couples traditional morphological analysis with taphonomic analysis and theoretical frameworks of intensification to ask new socially focussed zooarchaeological questions of these assemblages. Through this, both the procurement and processing methods utilized at Le6 and Le7 are identified and the significance of these choices is discussed. In so doing, the paper addresses possible specialization in both the hunting and the processing of large wild mammals. The socio-economic implications and potential drivers of these faunal choices are then considered within the broader context of the southern African Early Iron Age, and a potentially new faunal use strategy and site type are introduced.  相似文献

This article breaks new ground in examining how “new Irish” immigrant women have responded to the collapse of Ireland’s Celtic Tiger economy and the different forms of gender discrimination and marginalisation they face both within their minority ethnic communities and the Irish host society. It approaches Ebun Akpoveta’s Trapped: Prison Without Walls (2013) as an exemplary work of fiction which exposes unresolved injustices and inequalities suffered by immigrant women. Akpoveta creates a narrative that complicates previous representations of cultural encounters between newcomers and long-established members of Ireland’s host society, not least because her Nigerian female protagonist arrives as a postgraduate student rather than an asylum seeker or refugee. She fictionalises female experiences of marginalisation, gender-based violence and family dysfunction within an all-Nigerian family that outwardly appears to be a model of integration and social inclusion in an open and welcoming Irish multicultural society.  相似文献

Abstract

Ever since Jimmy Rabbitte proffered his oft-quoted “niggers of Europe” line in Roddy Doyle’s The Commitments (1987), contemporary Irish culture, especially during the boom years, was characterised by an insistent revisiting of popular music as a metaphor for interracial and/or intercultural connection or understanding. Cross-cultural identification through music may be seen, in Werner Sollors’s memorable terms, as an eschewing of “descent” relations in favour of “consensual” relations. This essay revisits the music metaphor as it has manifested itself in Irish fiction since it was announced officially that Ireland had entered recession in 2008. Specifically, it explores Kevin Curran’s Beatsploitation (2012) and Joseph O’Connor’s The Thrill of It All (2014) arguing that, through their deployment of the music metaphor, the novels stage the murky politics of contemporary Irish iterations of consent and descent. By exposing the extent to which the rhetoric of Irish economic recovery is yoked to paradoxical invocations of volitional and ancestral Irishness, the novels urge their readers to consider the ways in which discourses of economic recovery work to reinforce and perpetuate patterns of exclusion and marginalisation established during the Celtic Tiger years.  相似文献
