Impact of planning mandates on local plans: a multi-method assessment

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.     

Obsidian sources in highland Yemen and their relevance to archaeological research in the Red Sea region

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.     

Variable nucleotide tandem repeat (VNTR) typing of two palaeopathological cases of lepromatous leprosy from Mediaeval England

Using ancient DNA methods, we have examined in detail two archaeological cases of leprosy from Mediaeval England. The first was a child skeleton with rhino-maxillary changes typical of lepromatous leprosy (LL). The second case was the skeleton of a male adult who showed both typical rhino-maxillary changes and osteitis/periostitis on the leg and foot bones. Bone powder was sampled from both cases and DNA extracts were prepared. These were subjected to a series of polymerase chain reactions (PCRs) specific for regions on the Mycobacterium leprae genome. The repetitive element RLEP was used for confirmation of M. leprae DNA and then three polymorphic regions were successfully amplified and sequenced to determine the number of variable nucleotide tandem repeats (vntr) at these loci. These were the microsatellite regions ML2344 and ML2172 and the minisatellite region ML0058. Genotyping data from the strains preserved within the skeletal remains were compared with those obtained for a reference strain of M. leprae. Variation at these three loci was found between both burials and the reference strain, indicating that vntr typing of LL cases from the archaeological record is a useful way of confirming disease and an additional means of authenticating aDNA data. This demonstrates the feasibility of targeting multiple loci for phylogenetic studies of leprosy strains from archival sources.     

Introduction: Disability Policy as an Emerging Field of Mainstream Public Policy Research and Pedagogy

The purpose of this two-part symposium of the Policy Studies Journal is to broaden theconcept of disability policy from one that has relevance onlyforpeople interested in that substantive area to that of a major field of social policy having ramifications for the study and teaching of public policy broadly construed. The goal is for experiences in disability policy to be regarded in the same way that experiences in Other substantive areas, such as environmental policy, other social services, and civil rights, illustrate broader themes in areas such as public management, policy analysis, or ethics.

Experimental study of aqueous fluid infiltration into quartzite: implications for the kinetics of fluid redistribution and grain growth driven by interfacial energy reduction

To investigate the kinetics of interfacial energy‐driven fluid infiltration, experiments were carried out in a quartzite–water system at 621–925°C and 0.8 GPa. Infiltration couples were made by juxtaposing presynthesized dry quartzite cylinders and fluid reservoirs. The infiltration process was confirmed by the presence of pores at the quartzite grain edges. As predicted from theoretical considerations and previous experiments, wetting fluids such as pure water and NaCl aqueous solution infiltrated into quartzite, whereas nonwetting CO₂‐rich fluids did not. Newly precipitated quartz layers at the surfaces of the infiltrated sample proved that infiltration took place by a dissolution–precipitation mechanism. The enhancement of grain growth by fluid infiltration was observed over the entire range of experimental temperatures. The fluid fraction, gauged by the porosity of the run products, increases at the infiltration front and then decreases towards the fluid reservoir to form a high‐porosity zone with a maximum porosity of 2.3–2.9%. As infiltration proceeds, the high‐porosity zone advances like a travelling wave. This porosity wave is probably caused by a grain curvature gradient resulting from preferential grain growth in the infiltrated part of the quartzite, perhaps combined with other factors. The infiltration kinetics were modelled with a steady‐state diffusion model over the high‐porosity zone. The solubility difference between dissolving and precipitating grains was deduced to be 2 × 10^?2?3 × 10^?1 wt %. The experimentally obtained infiltration rate of aqueous fluid in the steady‐state diffusion regime (2 ± 0.5 × 10^?8 m sec^?1 at 823°C) is much faster than the estimated metamorphic fluid flux rates, so that interfacial energy‐driven fluid redistribution in quartz‐rich layers could significantly contribute to the fluid flux in high‐grade metamorphism, at least over a short distance. Cathodoluminescence observations of the run products revealed that the grain growth of quartzite in the presence of fluid proceeds extensively, which would promote the chemical equilibration between fluid and rock more effectively than would volume diffusion in quartz crystals.     

Les lois de la nature à l'âge classique la question terminologique

Four propositions relative to the laws of nature in the classical period must be noted. 1. Certain regularities in phenomena had been discovered. 2. A concept of law had emerged. 3. Classical science is characterized by the introduction of the notion of the legality of nature. 4. New uses of the word «law» had appeared in scientific texts. This article is devoted to the analysis of only this last proposition, that is to say to a terminological problem. First we will describe the semantic uses of the word «law» that may have contributed to the constitution of its classical meaning: its specific usage, disciplinary usage, usage in physics, in mathematics, in metaphysics. Second we will analyze the various moments of the diffusion of the word in the sciences in the xvii^th century. The general thesis defended in the end is that if the term «law» had indeed been used in science with no reference to a law-giving God prior to the xvii^th century, only this reference, that is, the coming together of its physical and its metaphysical usage, allowed its generalization in the period between the xvii^th and xviii^th centuries.
