Julfar was a major port town of the Persian Gulf during the fourteenth and fifteenth centuries AD. A possession of the Hormuzi empire, it was a lucrative source of taxes and pearls, and a port of trade for northern Oman, tapping into maritime trading networks connecting the Middle East with Africa, India, Southeast Asia and China. The site is found north of modern Ras Al-Khaimah, UAE. Julfar Al-Nudud was previously considered to be a late suburb of an urban core, Julfar Al-Mataf, and is located on a creek opposite the latter. However, excavations in 2010 indicated that Al-Nudud was part of the original urban core, which had grown up on either side of the creek. Moreover, re-examination of previous work in Al-Mataf, where a large mosque and fortification were excavated (by British and French teams), shows that the two areas followed different trajectories. Significant occupation in Al-Nudud and southern Al-Mataf (revealed by previous Japanese excavations) ended before the start of the sixteenth century, while use of the mosque and fort in central Al-Mataf continued into the seventeenth century, albeit discontinuously. A revised concordance of the phases derived from the work of various archaeological teams is therefore proposed.  相似文献

The topics of the territorial structure of the German states and the strategic development of the metropolitan regions are at first glance two completely separate discourses. However, this paper demonstrates that the development of the metropolitan regions in Germany, supported by Federal Spatial Planning, has at least in some cases been influenced by the possibility of offering an alternative to state restructuring and that the metropolitan regions today continue to represent a basis for interstate cooperation. The in-depth observation of four cross-state metropolitan regions makes clear that different development paths have been followed. Thus, while certain metropolitan regions have distanced themselves from issues relevant to interstate cooperation, the examples of Hamburg and Berlin-Brandenburg show the value of metropolitan regions for cooperation between states and as an alternative to state restructuring.  相似文献

This paper addresses how the growth of tourism global production networks (GPNs) based in Kenya and Uganda created uneven social upgrading outcomes for workers and communities. A tourism GPN and social upgrading framework follows a global political economy approach to analyzing tourism development and labor in diverse tourism geographies. Two tourism GPNs are investigated: Mombasa, Kenya, and Murchison Falls National Park, Uganda. Four main findings emerge: (1) governance relationships between tour operator and accommodation firms directly impacted social upgrading outcomes for hotel workers and indirectly for excursion workers; (2) excursion workers and community members had precarious connections to tourism GPNs; (3) public governance and collective power were key components to social upgrading while supporting its unevenness; and (4) societal embeddedness constructions around gender and regional space influenced worker and community social upgrading potential. Social upgrading is shaped by a confluence of firm, institution, geography, and labor conditions that differentially materializes in specific tourism GPN arrangements.  相似文献

Reflecting on a recently completed ethnographic research project, I try to understand how things that may seem marginal to my central question nonetheless remain active within my arguments in unanticipated ways. I begin with an overview of my original research aims and activities before presenting eight marginal examples from fieldwork. I conclude with a meditation on the epistemic force that the marginal must be understood to exert on projects of knowledge production.  相似文献

Abstract

Dopamine is among the most well‐researched neurotransmitters at the present time. For the first half‐century of neurotransmitter research, however, interest in dopamine was minimal, and only a few scattered groups of researchers studied it. It was their research that stimulated current interest, and provided the background for our present understanding of this important substance. By the late 1950s, it was clear to these individuals that dopamine served an important physiological role in mammalian brains, and that its role was most likely that of a central nervous system agonist. Soon after this, dopamine, or more specifically the depletion of dopamine, was clearly implicated in Parkinson's disease. This paper looks at the early history of the physiological roles of this intriguing compound.  相似文献

The 2006 “Thematic Strategy on the Urban Environment” is the first piece of official European Union (EU) policy solely focused on the urban environment. It follows a process of several years in which the EU has tried to promote an integrated approach to urban management. During the 2005–2007 “Liveable Cities” project, reflection was given to the “Thematic Strategy”. This resulted in important critiques on the EU's approach to the urban environment. Explaining how the initial top-down approach chosen by the EU contributed to the perceived “failure” of the “Thematic Strategy”, suggestions are made for alternative approaches to the creation of liveable cities in Europe.  相似文献
