Gravity models with fixed coefficients have been used to explain the trade flows between countries different in income levels and separated by long distances. It is unrealistic to assume that these models can hold with the same parameters across very heterogeneous countries. This paper proposes and estimates an international trade model with variable coefficients constructed by combining Pöy-hönen's and Linnemann's gravity-based trade models via the expansion method. 相似文献

Pilgrimages are often messy affairs, not only leaving all sorts of material detritus behind, but also in many cases severely damaging or even destroying the sites that are visited as part of journeys to a sacred place. As such, this immensely popular religious tradition constitutes a social practice that is deeply tied to the landscapes and places that are considered to be holy and thus principally worthy of preservation (at least by many definitions of heritage), but which also in many cases ultimately consumes them over time, sometimes in very direct ways that immediately affect their physical state. This paper explores the contemporary and historical dimensions of this paradox, and considers the wider implications of seemingly destructive uses of sacred space by investigating the social and religious significance of so-called ‘pilgrims’ gouges’ observable at numerous pilgrimage sites in the Eastern Mediterranean. It, thereby, sheds light on the connections between the religious experience of pilgrimage and the material consumption of sacred places by juxtaposing cases from contemporary Islamic Syria and ancient Egypt, providing a long-term perspective on the use and consumption of sacred places. Lastly, it discusses the potential ramifications of the gouges for current approaches to heritage management and conservation. 相似文献

We have investigated the survival of PCR-amplifiable mitochondrial and nuclear DNA in a small number of modern and medieval bovine leather samples. The results of this preliminary investigation demonstrate that, while no nuclear DNA can be PCR-amplified from any of the specimens, mitochondrial DNA can be amplified from all samples. To investigate this contrasting pattern of DNA survival further, we have vegetable-tanned cow skin in our own laboratory, and directly assayed the survival of PCR-amplifiable mitochondrial and nuclear DNA at each step of the process. The results indicate that nuclear DNA is reduced to sub-amplifiable levels as a result of the tanning baths, whereas amplifiable mitochondrial DNA survives the complete process. Our results suggest that old and archaeological bovine leather may represent a useful source of genetic information, although this information will most likely be limited to that which can be gained from mitochondrial DNA. 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

In 2004 excavations at the Barbar Temple dating to c. 2000 BC established that the function of the southeastern subterranean channel connected to the temple pool was to supply the pool with water and not to divert water away from the pool. North and west of the temple the oval terrace wall of its third phase was located. In the centre of the Northeast Temple the remains of a shaft-stairway leading down to a well-chamber was uncovered and shown to be furnished with two subterranean channels leading water into the chamber. South of the Northeast Temple a house with late pottery was excavated. Two stamp seals and two seal-impressed tokens were found. 相似文献
