ABSTRACT The twenty‐first century will be one of intensified urbanization, on a scale never before experienced. How do urban systems and individual cities change and develop? The social sciences have many different approaches to analyzing the economic, social, and spatial dimensions of urban change. We inventory some of these approaches and their implications for public policy toward cities, urban change, and economic development. 相似文献

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

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

The Tekta? Burnu ship (440–425 BC) sank along a rough and desolate stretch of the Turkish Aegean coast. Archaeological excavation of the shipwreck site by the Institute of Nautical Archaeology at Texas A&M University resulted in the retrieval of hundreds of small fragments from the ship's wooden hull and its metal fasteners. Recent study of this artefact assemblage suggests that the coastal trader was built with pine planks and made‐frames, and assembled by a shell‐based construction method. Fasteners include pegged mortise‐and‐tenon joints and double‐clenched copper nails, and the ship may have had laced extremities consistent with other contemporaneous shipwrecks. 相似文献

Since the early 1990s, nature conservation organizations in Eastern and Southern Africa have increasingly attempted to integrate their objectives with those of international development organizations, the land-use objectives of local communities and the commercial objectives of tourism businesses, in order to find new solutions for the protection of nature and wildlife outside state-protected areas. The increased inclusion of the market in conservation initiatives has led to diverse institutional arrangements involving various societal actors, such as private game reserves, conservancies and conservation enterprises. The Koija Starbeds ecolodge in Kenya – a partnership between communities, private investors and a non-governmental organization – serves as a case study for emerging institutional arrangements aimed at enabling value creation for communities from nature conservation. Based on a content analysis of data from individual semi-structured interviews and focus group interviews, as well as a document and literature review, this article reveals a range of benefits for community livelihood and conservation. It also identifies a range of longer term governance challenges, such as the need to address local political struggles, the relations between partners and transparency and accountability in the arrangement. 相似文献

In this paper, we explore the role of place in drinking practices of young people in the context of rural Estonia. We draw on a participatory research project carried out during seven months with a group of eight young men (15–18 years of age). We focus on three locations identified as the most popular drinking places by the young men in our research – familial homes, a local hamburger kiosk and the outdoors. The findings indicate that youth drinking practices as well as the drunkenness-related risks are spatially contingent. Characteristics of individual drinking locations influence the negotiation of local and national opportunities, restrictions and attitudes toward drinking, and the associated risks. We argue that, when developing public health tools, it is fruitful to pay attention to the local context and specific places in which young people's drinking practices are negotiated. 相似文献

This paper presents an analysis of networks among small and medium-sized enterprises in the Irish biotech sector. The study applies social network analysis to determine the structure of networks of company directors and inventors in the biotech sector. In addition, on the basis of interviews, this article analyses the extent of actual knowledge flow through these industry networks. The paper makes both a theoretical and methodological contribution to innovation network research. In relation to theory, the findings of the social network analysis indicate that the extent and path of knowledge flow are influenced by both the type of knowledge in question and whether the network is of a formal or informal nature. Methodologically, the results of this paper raise questions about the application of social network analysis in innovation studies. 相似文献

Using the case study of a New Zealand rugby club, in this article, we highlight the role of gender and performance in place attachment. We discuss various performances that contribute to achieving a sense of attachment of club members to the (imagined) community of the rugby club and the different physical spaces of its home ground. Even though performances are played out and read against the backdrop of a popular discourse of New Zealand rugby masculinity, we did not observe characteristics of stereotypical ‘rugby masculinity’ in all rugby places, nor were performances the same throughout one day. Instead, variations were found depending on whether performance was ‘front stage’ or ‘backstage’. 相似文献
