An increasing number of subnational government bodies mandate municipalities to establish a vision for their future development with a local plan. Outside the U.S., few studies have assessed whether these mandates succeed at increasing formal quality, policy focus and implementation of local plans. In addition, the reasons that prompt governments to impose mandates remain unclear. To tackle these issues, we used a multi-method approach combining interviews, plan content analysis and questionnaires to compare mandated and voluntary planning in Switzerland. Our analysis reveals that mandates only have limited impact on local plans. In particular, they do not produce higher quality plans than voluntary planning and do not improve implementation of policies. Our results may imply that (a) planning mandates from subnational governments are ineffective in general or (b) Swiss mandates in particular entail too few requirements and enforcement mechanisms to show a clear effect. Further studies could explore this issue empirically by comparing the characteristics of different planning mandates and assessing their effect on the quality and implementation of local plans. Alternatively, future research efforts could also examine how to find a compromise between mandated and voluntary planning in order to increase local commitment towards plan making. 相似文献
The Red Sea and surrounding area formed through dynamic uplift and rifting of Afro-Arabia, and associated volcanism (both oceanic and continental in character). As a result, volcanic landforms and products are widespread and play a vital role in the natural and cultural landscapes of humans occupying the highlands and lowlands on both sides of the Red Sea. Archaeologists have suggested for some time that Afro-Arabian trade in obsidian had its roots in the prehistoric period and that the region was very likely the source of an abundance of obsidian artefacts found as far afield as Egypt, the Persian Gulf and Mesopotamia, and which do not match the well-known Anatolian, Transcaucasian or Mediterranean sources. Nonetheless, the southern Red Sea is one of the few obsidian-rich regions exploited in antiquity that has been barely investigated. In this paper, we highlight new geochemical analyses (carried out by LA-ICP-MS) of obsidian sources in Southern Arabia and beyond, that enhance our knowledge of obsidian exploitation from as early as the Neolithic period, and which enable us to evaluate the role that highland Yemen obsidian sources played in prehistoric long-distance trade. In addition, we present new evidence for explosive volcanic eruptions that likely affected the highland populations of Yemen in the 4th millennium BC. 相似文献
Alexander the Great was struck by a stone at the Siege of Cyropolis in 329 BC and was rendered temporarily blind and inaudible as a result. Although other authors have written extensively about the likely pathological effects of this injury, none have suggested carotid artery dissection as a possible cause. We present evidence that this should be considered as a differential diagnosis and how it might explain an unusual symptom seen at his deathbed in Babylon six years later. 相似文献

This report describes the results of fieldwork carried out in the Zemplén Mountain area of north-eastern Hungary in 1975. The aim of this work was to locate and sample geological sources of obsidian which may have been used by prehistoric man. These sources are of increased importance since the work of Nandris (1975) showed that the Romanian “sources” do not produce workable obsidian. During the fieldwork three sources in Hungary were visited and sampled; one of these was the previously unlocated source of Csepegö Forräs. A number of other possible localities for geological obsidian are mentioned in 19th and 20th century geological and archaeological literature, and the present state of knowledge with regard to these is summarized. Further sources exist in central and in south-eastern Slovakia. These sources were not visited but material has been obtained from both areas. The central Slovak sources do not produce workable obsidian and are not therefore relevant to archaeological studies. Obsidian from three localities in south-eastern Slovakia is of good glassy quality and further fieldwork is now needed to check the validity of these localities as geological sources. Reference is made to obsidian sources in the western U.S.S.R., and the problem of the use of tektites in archaeological sites is discussed.The obsidian samples obtained during this work are currently being analyzed using neutron activation, in order to characterize the sources on the basis of their trace element analysis and thus to relate them to archaeological obsidian from central and eastern Europe. 相似文献
