This paper argues for a rediscovery and reassessment of the contributions that humanistic approaches can make to critical and radical geographies. Based on an exploration of the archives of Anne Buttimer (1938–2017) and drawing upon Paulo Freire's notion of conscientização (awareness of oppression accompanied by direct action for liberation), a concept that inspired the International Dialogue Project (1977–1988), I explore Buttimer's engagement with radical geographers and geographies. My main argument is that Buttimer's notions of “dialogue” and “catalysis”, which she put into practice through international and multilingual networking, should be viewed as theory‐praxes in a relational and Freirean sense. In extending and putting critically in communication literature on radical pedagogies, transnational feminism and the “limits to dialogue”, this paper discusses Buttimer's unpublished correspondence with geographers such as David Harvey, William Bunge, Myrna Breitbart, Milton Santos and others, and her engagement with radical geographical traditions like anarchism, repositioning “humanism” vis‐à‐vis the fields of critical and radical geography.  相似文献

In the great civilisations of the past, shapeshifting promised a restoration of order in turbulent times in return for the deference of loyal subjects. It was a strategy of the powerful to maintain advantage and could also be used to bind opponents to an undesired form. This study finds its resonance in the contemporary shapeshifting that is the supposed transition from the fossil fuel economy. With reference to the fusion of oil, grain and sugar companies in Brazil's ethanol sector, it explores how amidst economic, environmental and political insecurity these “old villains” of the carbon economy have fused and emerged as the “new heroes” of the green economy. Accounts of dissenting rural subjects, however, unveil the mythical nature of avowed social gains from this shapeshifting. Amidst rural conflict and a successive weakening of regulation, it becomes evident how their petrification, in a metaphorical and increasingly literal sense is required.  相似文献

This review discusses recent challenges to the welfare state arising from the Great Recession (GR). The GR was a significant event for social policy analysts, as it tested the responsiveness of welfare systems in the midst of a recent trend toward austerity politics in advanced economies. Social policy changes were part of the toolkit advanced democracies used to respond to the GR, and the welfare state mitigated the consequences of the GR. However, a stark limitation of the social safety net in the United States was the failure to assist immigrant households. The nexus of immigration and social policy is likely to be a significant controversy as we consider the meaning of social citizenship.  相似文献

This article deals with the access to global markets via inclusionin global value chains for private clothing producers in Vietnam.It argues that ‘chain entry barriers’ are not onlyconstructed by global buyers as it is often suggested, but alsoby political–economic processes in Vietnam. The marketorientations of four segments of private enterprise owners isexamined and shown to correspond to their ethnicity, originand location in northern or southern Vietnam. It is argued thatthis is mostly because these factors influence access to thestate system, where export-related resources are found.  相似文献

Twenty‐six samples from domestic assemblages of 9th–12th century Córdoba were subjected to electron microprobe analysis. The results reveal two main compositional types. The first, encountered in 13 of the samples, seems to result from the combination of plant ashes with high‐impurity sand, and has some contemporary parallels from Syria and Egypt. The second type is a lead–soda–silica glass, encountered in a relatively high proportion of the glasses (11 of the 26 sampled), possibly formed by the addition of lead metal to existing glasses and with very few known parallels. These are among a very small number of results available to date on the chemical composition of glasses from medieval Spain, and the presence of a high proportion of lead–soda–silica glasses is particularly interesting, possibly indicating a technological practice unique to, or originating in, the western Muslim world.  相似文献

Despite their theoretical and political potential, recent debates on enclosure usually lack an effective consideration of how space is mobilized in the process of dispossession. This article connects the analysis of enclosure's general spatial rationality to a range of illustrations of its particular formations and procedures. Enclosure is understood as one of capitalism's “universal territorial equivalents”, a polymorphous technique with variegated expressions in time but also with a consistent logic that uses the spatial erosion of the commons to subsume non‐commodified, self‐managed social spaces. In response to the ever‐changing nature of commoning, successive regimes of enclosure reshape the morphologies of deprivation and their articulation to other state and market apparatuses in order to meet shifting strategies of capital accumulation and social reproduction. Through a spatially nuanced account of these phenomena, I outline a tentative genealogy of enclosure formations that allows tracking diverse geographies of dispossession across different scales and regulatory contexts in various historical stages of capitalist development.  相似文献

Peel, J.S., February 2017. First records from Laurentia of some middle Cambrian (Series 3) sponge spicules. Alcheringa 41, 000–000. ISSN 0311-5518.

Spicules of the sponges Silicunculus Bengtson, Australispongia Dong & Knoll and Thoracospongia Mehl are described from the middle Cambrian (Cambrian Series 3) of North Greenland. The occurrences document the first records from the Cambrian of Laurentia of spicules initially reported from Australia. Obese spicules of Thoracospongia are now known to occur in strata of Cambrian Series 2 (Stage 4, Botoman) to Cambrian Series 3 (Stage 5 and Drumian) age in Australia, northern and southeastern Siberia and in the uppermost Henson Gletscher Formation (Cambrian Series 3, Stage 5) of western Peary Land. Morphologically similar obese spicules from the USA, Jordan, Iran and Sweden suggest an evolutionary trend towards armouring of the outer sponge surface during the middle and late Cambrian. New species described are Silicunculus saaqqutit sp. nov., Thoracospongia lacrimiformis sp. nov.

New challenges in management and restoration of archaeological sites require the utilization of advanced technologies and systems to assist in preserving the important legacy of human heritage. These challenges include monitoring and preserving of site landscapes, maintenance and rehabilitation of archaeological structures, and quality and safety management. In this research, an integrated methodology based on photogrammetry and Three-Dimensional (3D) Geographic Information System (GIS) is developed to capture and model essential details needed for the proper management of archaeological sites. Recent advances in digital imagery and modelling utilize photogrammetry as an efficient technique for 3D modelling of archaeological sites to derive accurate measurements of size, shape, position, and texture of objects using two-dimensional digital photographs. Spatial data that include aerial stereo photographs, satellite images, close-range photos, terrestrial surveying and Global Positioning Systems (GPS) are integrated within the design of the proposed model. The approach is validated with a case study of Ajloun Castle, one of the ancient and important preserved structures located in Jordan. Various sequential levels of details have been developed for the castle: Orthophoto, Digital Elevation Model (DEM), structures geometry and site layout and 3D textured model. The suggested methodology is expected to be efficient in modelling and documenting archaeological structures. The developed model is utilized to assess the management of archaeological structures through feasibility analysis, rehabilitation decisions, and safety planning.  相似文献
