Geographical fieldwork is being reinvigorated through pedagogical and methodological innovations. Yet, while there are many good ideas in circulation, there is less evidence of where these ideas are taking us: what students are getting out of them, and what significance they may have for the discipline. These questions are explored through case studies involving playful and multi-sensory fieldwork: collecting sounds, urban climbing, finding “accidental art” and getting lost. Students tend enjoy this approach to fieldwork, which inspires them to learn actively and creatively, fosters the acquisition of new skills and explores the broader possibilities of playful and multi-sensory geographies.  相似文献

During the past two decades scholars from a variety of different fields (law, history, journalism, political science) have written extensively about the development and implementation of the Unilateral Presidency. Because several explanations for unilateral action have been posited, we provide a thorough test of three theories of executive unilateral action. Applying a newly-developed methodology to the most comprehensive dataset of unilateral presidential directives to date, results of the Bayesian Poisson Vector Autoregressive model suggest that although executive orders, memoranda, and proclamations are all strategic tools that presidents utilize to unilaterally alter policy, fundamental differences exist between them, as well as the inter-dependence among them. More important, our results show that whereas the percentage of bills passed is related to presidential proclamations, legislative activity actually depends on the number of executive orders issued. However, CQ success scores are related to both executive orders and presidential proclamations. We also find that presidential ideology and congressional ideology are related to executive action, whereas the impact of divided government is at best only weakly related.  相似文献

Archaeological survey by the Qatar National Historic Environment Record Project (QNHER) in 2009, led to the discovery of a Neolithic flint scatter, a settlement and an ancient, raised shoreline associated with higher, mid‐Holocene sea levels at Wādī ?ebay?ān, north‐western Qatar (Al‐Naimi et al. 2010, 2011; Cuttler, Tetlow & Al‐Naimi 2011). The QNHER project is a collaboration between Qatar Museums and the University of Birmingham, which over the past five years has developed a national geospatial database for the recording of archaeological sites and historic monuments in Qatar. A significant aspect of the project involved archaeological survey and excavation in advance of major construction projects. Between 2012 and 2014 excavations at Wādī ?ebay?ān revealed a burial of a typology previously unknown in Qatar, the unmarked graves (Cuttler, Al‐Naimi & Tetlow 2013).  相似文献

The vector assignment p‐median problem (VAPMP) is one of the first discrete location problems to account for the service of a demand by multiple facilities, and has been used to model a variety of location problems in addressing issues such as system vulnerability and reliability. Specifically, it involves the location of a fixed number of facilities when the assumption is that each demand point is served a certain fraction of the time by its closest facility, a certain fraction of the time by its second closest facility, and so on. The assignment vector represents the fraction of the time a facility of a given closeness order serves a specific demand point. Weaver and Church showed that when the fractions of assignment to closer facilities are greater than more distant facilities, an optimal all‐node solution always exists. However, the general form of the VAPMP does not have this property. Hooker and Garfinkel provided a counterexample of this property for the nonmonotonic VAPMP. However, they do not conjecture as to what a finite set may be in general. The question of whether there exists a finite set of locations that contains an optimal solution has remained open to conjecture. In this article, we prove that a finite optimality set for the VAPMP consisting of “equidistant points” does exist. We also show a stronger result when the underlying network is a tree graph.  相似文献

In his “Méthode nouvelle,” an anonymous article in the Bibliothèque universelle of 1686, John Locke described his way of collecting excerpts in notebooks and retrieving relevant entries. The well-known practice of entering textual passages in commonplace books sits uneasily with Locke's criticism of received opinion and authority. Is it possible that he used any of these notes to think with? I suggest that the conditions for this were provided by Locke's interactions with some of his notes, including those which recorded observations, testimonies and experiments. As well as labelling excerpts and other notes with topical Titles, Locke sometimes added precise bibliographical citations, transferred material across notebooks, interpolated his own signed reflections and queries, and (eventually) dated entries.  相似文献

The NeoArabia project tries to understand how environmental, social, economic and technological factors work in concert to influence settlement and abandonment along a latitudinal transect of 1200 km from UAE to southern Oman. This region was affected by wide north–south variations in the Indo-Arabian monsoon, marine upwelling activity and eustatic variations in the Mid-Holocene. On the local settlement scale, this transect is based on fine stratigraphic excavations and permits the reconstruction of the site formation processes and site catchment analysis. A large number of studies have been conducted on the Ruways-1 site, focusing on a deep stratified sequence corresponding to three millennia of occupation. These studies include on-site climate-environmental signal analysis, local palaeogeography and environmental reconstruction, reservoir effect studies, typo-technological studies, palaeoeconomic strategies, anthropological studies, sclerochronological studies and, finally, site formation processes, the understanding of which makes it possible to explain the potential and limits of the archaeological excavation. The first results confirm the richness of these archaeological archives for documenting the socio-environmental dynamics, but also the richness of its complex sedimentary structure and the importance of conducting fine and multidisciplinary excavations to answer questions about the rhythms and functions of occupations and the causalities of socio-environmental changes.  相似文献

The concept of therapeutic landscapes has been used as a way to critically understand how health and well-being are related to place. However, traditional discourses on therapeutic landscapes have been constructed from an anthropocentric perspective, completely ignoring and silencing the agency and experiences of non-humans. Building on the idea of therapeutic spaces as assemblages, I highlight the heterogeneity of elements that come together to produce therapeutic space. Mobilizing empirical research undertaken in spaces involved in the practice of ‘care farming’, I demonstrate how non-human presence actively creates and facilitates a therapeutic engagement with place. However, with this recognition of the non-human in therapeutic spaces, there is a need to discuss animals’ contested positions, and question the ways in which being part of these assemblages impacts animals; for whom are these landscapes therapeutic? Thus, this article advocates a critical understanding of the role of non-human animals as both co-constituents and co-participants of therapeutic spaces, moving from framing therapeutic spaces – and the animals within them – purely in relation to human needs and desires.  相似文献
