In this article, we argue that the governance of gig work under conditions of financialised platform capitalism is characterised by a process that we call “dual value production”: the monetary value produced by the service provided is augmented by the use and speculative value of the data produced before, during, and after service provision. App-governed gig workers hence function as pivotal conduits in software systems that produce digital data as a particular asset class. We reflect on the production of data assets and the unequal distribution of opportunities for their valorisation, after which we survey a number of strategies seeking data-centric worker empowerment. These strategies, we argue, are crucial attempts to push back against platform capitalism’s domination, bankrolled by what we term “meta-platforms”. Ultimately, it is the massive wealth and synergetic capacities of meta-platforms that constitute the most formidable obstacle to worker power and social justice in increasingly data-driven societies. 相似文献

This paper discusses studies of the development of river conservancy in modern China, and the role of engineers-in-chief in river improvement planning on rivers such as the Hai-ho (Haihe) and the Whangpoo (Huangpu). It discusses the introduction of foreign hydraulic dredging technology and management into two major Chinese ports. It then analyses the process by which two agencies of the Chinese government absorbed and adjusted this technology to suit local circumstances in the treaty ports of Tianjin and Shanghai beginning in the 1890s. Without prior experience in river conservancy, the conservancy boards adopted a range of foreign technologies. This allowed them to develop into major institutions that facilitated increasing trade flows between China and the rest of the world. Of particular significance in this process of technological change was the role of the expatriate engineers-in-chief who were employed as chief executive officers of both agencies. They were responsible for establishing the operations of the agencies, accommodating an increasing range of responsibilities such as financial and human resource management, and training Chinese engineers and managers for senior positions until they were ready to replace the expatriate engineers-in-chief after the 1930s. 相似文献

The community energy sector is widely understood to be a pluralistic sector, encompassing a broad range of aims, motivations, and practices. This heterogeneity is, however, still not very well understood. Dominant analytical frameworks in the study of energy geographies offer little in the way of exploring the diversity of motivations, visions, and social relations that are present within the community energy sector, nor their causes or consequences. Drawing on the notion of ‘critical pluralism’, this paper aims to highlight the diverse range of sociotechnical configurations that make up this sector in Scotland, and begins to discuss some potential causes and consequences. To do so, it presents a novel community energy typology, based on an analysis of technical and social dimensions of 367 projects in Scotland. This shows that whilst the Scottish community energy sector contains a broad range of motivations, technologies, and social practices, the sector has become dominated by groups for whom energy generation is a means to achieve local socio-economic development. The paper discusses the community-level and policy drivers that may have contributed to this. It also discusses how we can begin to understand a diverse sector’s ability to affect the wider structures in which it operates. 相似文献

Field courses are essential for subjects like Earth Sciences, Geography and Ecology. In these topics, GIS is used to manage and analyse spatial data, and offers quantitative methods that are beneficial for fieldwork. This paper presents changes made to a first-year Earth Sciences field course in the French Alps, where new GIS methods were introduced. Students use GIS in preparation to explore their research area using an elevation model and satellite images, formulate hypotheses and plan the fieldwork. During the fieldwork, a pilot group managed their field-observations using GIS and made digital maps. Students praise the use of quantitative digital maps in the preparation. Students made use of the available techniques during the fieldwork, although this could be further intensified. Some students were extra motivated due to the technical nature as well as the additional analytical possibilities. The use of GIS was experienced as a steep learning curve by students, and not all staff members are confident in supervising students using GIS, which calls for a sufficient preparation and training of both students and staff. The use of GIS adds abstract analyses and quantitative assessment, which is a complementary learning style to fieldwork that mostly focuses on practical skills. 相似文献

Zhen, Y.Y., Wang, G.X. &; Percival, I.G., August 2016. Conodonts and tabulate corals from the Upper Ordovician Angullong Formation of central New South Wales, Australia. Alcheringa 41, xxx–xxx. ISSN 0311-5518.The Angullong Formation is the youngest Ordovician unit exposed in the Cliefden Caves area of central New South Wales. Its maximum age is constrained by a Styracograptus uncinatus graptolite Biozone fauna at the very top of the underlying Malongulli Formation, but the few fossils previously reported from higher in the Angullong Formation are either long-ranging or poorly known. From allochthonous limestone clasts in the middle part of the formation, we document a conodont fauna comprising Aphelognathus grandis, A. solidum, Aphelognathus sp., Aphelognathus? sp., Belodina confluens, Drepanoistodus suberectus, Panderodus gracilis, Panderodus sp., Phragmodus undatus, Pseudobelodina inclinata and Pseudobelodina? sp. aff. P. obtusa, which supports correlation with the Aphelognathus grandis Biozone (late Katian) of the North American Midcontinent succession. The species concepts of Aphelognathus and Pseudobelodina are reviewed in detail. Associated corals are exclusively tabulates, dominated by agetolitids, including Agetolites angullongensis sp. nov., Heliolites orientalis, Hemiagetolites breviseptatus, Hemiagetolites sp. cf. H. spinimarginatus, Navoites sp. cf. N. circumflexa, Plasmoporella bacilliforma, P. marginata, Quepora sp. cf. Q. calamus and Sarcinula sp. Affinities of the coral fauna from the Angullong Formation are closer to faunas from northern NSW and northern Queensland than to the locally recognized Fauna III of late Eastonian age in central NSW. We propose a subdivision of Fauna III to account for this difference, with the late Katian Fauna IIIB characterized by the incoming of agetolitid corals. The currently known distribution of representatives of this group with adequate age constraints suggests that agetolitids possibly originated in North China, subsequently migrating to Tarim, South China and adjacent peri-Gondwanan terranes while also spreading eastward to northern Gondwana, where they progressively moved through eastern Australia to reach the central NSW region by the early Bolindian.Yong Yi Zhen* (yong-yi. zhen@industry. nsw. gov. au) and Ian G.

探索中国的参与式博物馆原则 总被引:1,自引:0,他引:1
浙江大学文物与博物馆学系联合荷兰阿姆斯特丹艺术大学开展的"参与式博物馆:机遇、挑战与问题"工作坊每一周都安排不同的教学活动。第一周熟悉主题,接下来是参与式展示、参与式征集、参与式研究,最后进行工作坊成果总结与思考。博物馆1.0传统模式是博物馆自己制作展览、自己发布内容和信息,观众只需要被动接受。而现在的博物馆2.0应该是由观众创作和生成内容,并与其他观众和博物馆工作人员进行分享和交流的一个平台。参与式博物馆是一种新的博物馆理念,其核心应该是创造、分享、互动、交流,博物馆是一个观众能够围绕其内容进行创作、分享并成为与他人交流的场所。 相似文献

Recent excavations in south‐eastern Wadi ‘Araba in Jordan have revealed the first early Islamic‐period copper‐smelting site known in the eastern side of the valley, which extends south of the Dead Sea to the Gulf of ‘Aqaba. Five test pits were excavated in 2012 at Khirbat al–Mana‘iyya, a prominent copper‐smelting camp in south‐eastern Wadi ‘Araba, Jordan. The results of these excavations demonstrate that the site was primarily active in the seventh–ninth century AD. Its distance from the copper sources of south‐west ‘Araba suggests that its location was chosen based on proximity to wood and water resources, rather than copper ore deposits. The discovery that the site dates to the early Islamic period has implications for previous and future work in south‐east ‘Araba. In particular, it challenges the common—until now—view of the region as virtually devoid of settlement during this period. 相似文献

While Indonesia’s efforts at countering violent extremism have enjoyed some successes, a section of its Islamist community remains committed to militant jihadism. The return from overseas of hundreds of militants linked to ISIS means that there is now a greater need than ever for interventions to prevent radicalisation – and for programs to reintegrate militants back into society. Drawing on 20 selected interviews with former jihadists, this article asks how successful official efforts have been at disengaging those convicted under Indonesia’s Anti-Terrorism Law from violent extremism. A significant minority remain welded to a militant mindset: “committed jihadists” who are likely to reoffend. Some former jihadists have “disengaged provisionally” but remain vulnerable: they have only disengaged for tactical or practical reasons. Yet some have also begun to disengage emotionally. While they may not disavow completely the use of force, these “provisionally deradicalised” activists have moved closer to that minority of interviewees who are “fully deradicalised”. Using this four-part typology of the pathways by which some militant jihadists have disengaged but others have not, this article finds that disengagement is a gradual process shaped by social networks. Consequently, it is suggested that a variety of methods be used to promote disengagement both before and after inmates leave prison. 相似文献
