Digital media scholarship is burgeoning. However, there remains a paucity of queer geographies accounting for hybridity and multi‐directionality of coexisting, variegated and embodied spaces produced through spatial media nor the technologies that enable these media (smartphones, tablet computers, and self‐tracking devices). Bringing together literatures on sexuality and the first and second iterations of the internet, this article extends debate about the uneven and paradoxical queer geographies of location‐aware applications (Tinder and Grindr) and other spatial media now often taken as “composite” of queer cultures globally. The article encourages those with interest in the interrelationships between sexualities and space to emphasise further the historical, cultural, and political specificities of the places in which these diverse media are designed, developed, and consumed. The purpose of doing so, I contend, is to deepen knowledge of heightened commercialisation whilst unravelling complex questions of data ownership, privacy and cultural norms that could exacerbate disparities in sexual citizenship. 相似文献

The evolution of early Meissen body, glaze and colorant compositions is examined using X-ray fluorescence spectroscopy (XRF) measurements on three artefacts that can be accurately dated to the period 1723–c.1740. The results are interpreted based on recipes recorded in the earliest documents of the Meissen archives. The pure Aue kaolinite contains low levels of Ti and can be distinguished from secondary clays, for example, clay from Colditz. The excess Ti in the glaze versus the body reported earlier and confirmed by the present authors is explained by the exclusive use of Colditz clay for the glaze, as described in the recipes before 1730, providing a terminus ante quem for Meissen porcelain exhibiting this particular asymmetry. After 1730, the presence of elevated Ti in the body could serve as a marker for the experimental admixture of clays to Aue kaolinite to alter its properties. Based on the detection of As, Ba and Bi, it is suggested that smalt from Erzgebirge was the colorant for blue enamels until at least 1725. 相似文献

ABSTRACTThe source of the human voice is obscured from view. The development of the laryngoscope in the late 1850s provided the potential to see the action of the vocal folds during speaking for the first time. This new instrument materially contributed to the understanding of vocal fold neuroanatomy, neurophysiology, and neuropathology. The laryngoscope led to elaborated understanding of disorders that previously were determined by changes in sound. The objective of this paper is to detail the consequences of this novel visualization of the larynx, and to trace how it aided in the development of understanding of the movements of the vocal folds. This is demonstrated through an examination of the activities and practices of a group of London clinicians in the second half of the nineteenth century. 相似文献

Netflix has gained significant attention in Canada because it exemplifies the challenge posed by digital technology to Canada’s long-standing cultural policies. It is increasingly evident that such policies are limited in their ability to encourage foreign investment while safeguarding Canadian cultural expression. Indeed, the policies proposed thus far have generated “Canadian discontent” across the political spectrum, notwithstanding their promised benefits. This article uses Netflix to explore the cultural politics of cultural policy: the historical and political underpinnings that drive ongoing discussions about state intervention in culture. These politics include the debates about the effect of foreign investment on Canadian cultural sovereignty, and the ideological tensions within the notion of sovereignty itself, namely those between state and consumer and between center and periphery. Using a historiographical approach, this article investigates the controversy surrounding recent government responses to the disruptive force of foreign digital multinationals, such as Netflix. 相似文献

Synthetic biology is an emerging technology that will impact on the future security and prosperity of Australia. As a discrete policy area synthetic biology has not been explored in relation to Australian foreign policy. To begin this process an understanding of Australia’s genetic endowment, Australia’s agricultural endowment and those security concerns novel to synthetic biology need to be developed. The convergence of the biological sciences and the information sciences is creating novel security concerns that impact on Australian sovereignty, both mainland and the Antarctic Territories, plant and animal health, and defence medical infrastructure. These concerns cross many traditional disciplinary and policy boundaries, an awareness of this is required and a nascent national practitioner community can develop this further. Drawing from work conducted by the US and UK synthetic biology practitioner communities, this article lays out the unique touch points synthetic biology has on Australian foreign policy. 相似文献

We present the first full archaeometrical study of Kushan‐Sassanian pottery from the Buddhist monastic complexes at Kara Tepe (Termez, Uzbekistan), recovered both in the pottery workshop and in the monastery, using a combination of analytical methods (XRF, XRD, SEM–EDS and OM). The study allowed the identification of the reference group, the correspondent fabric, the raw materials used for its productions, some of the technological processes involved in manufacture and several weathering processes. All the results confirm that the kiln was supplying the religious community of the monastery with pottery, made using local raw materials, and highlight the possibility that the kiln could have supplied the nearby monastic complexes, where no kilns have been found. Further archaeological evidence indicates the existence of specialized potters working itinerantly at the broader Bactrian area. 相似文献

The San Francisco Bay Area in California is undergoing a technology‐driven wave of growth arguably more thoroughgoing than the first “dot‐com” bubble, fueling hypertrophic gentrification and tales of a deeply class‐divided, “Blade Runner kind of society”. While Silicon Valley is still the industry's employment center, San Francisco is seeing faster tech firm growth, and is transforming its downtown to become more “livable” and promoting public space as key to innovation. In this context, this paper offers a reading of urban public space not just as a consumption amenity but also as the “shop floor” of a labor process that goes beyond the walls of the firm to mobilize the social itself in the production of privately appropriated value. With innovation now the watchword of gentrification, the stakes of this shift oscillate between the total commodification of urban vitality and the recognition of the social process of value production itself. 相似文献

三国西晋时期越窑青瓷的生产工艺及相关问题——以上虞尼姑婆山窑址为例 总被引:1,自引:0,他引:1
三国西晋的越窑青瓷,品质、器类、装饰皆臻于顶峰。同时,生产工艺也达到极高的水准。文章以尼姑婆山窑址为例,从龙窑与窑具、装饰、成型、修坯、上釉、烧成等多个方面,论述了越窑青瓷的生产工艺,认为装饰、模制成型工艺最能代表当时的水平。这些复杂工艺在东晋以后失传,与北人南迁破坏了当地的制瓷传统,从而导致窑业萎缩的历史背景密切相关。 相似文献

It is well established that digital technology and code mediate bodies in space. The collapse of any supposed physical/digital divide has been amply documented to the extent that everyday life is now widely theorised in terms of hybridisation. What is less clear is what comes next for those participating in this hybridisation. This article examines what Kitchin and Dodge term the ‘social contour of software’ via queer male locative media users who collectively negotiate digital hybridisation in their everyday lives. Using qualitative interviews with 36 non-heterosexual men using apps such as Grindr and Tinder in London, UK, I explore how locative media refigures conceptualisations of community, technological efficiency and boundaries between private and public space. The study finds that users express ambivalence about their membership of queer ‘communities’, and are also unconvinced by online sociality. Apps expedite searches for new partners but prove deceptively time-consuming. Public and private space are being hybridised by locative technology, but common codes of conduct are slower to develop, leaving users unsure of how to navigate physical encounter. This article concludes that schema for queer men’s lives are increasingly promulgated digitally but may be uneasily embodied in everyday practice. 相似文献
