Design paths of federal intergovernmental cooperation

Actors rarely approach institutional design choices with a blank slate but are influenced by design choices made at earlier stages. How does institutional design evolve over time and are there specific paths to deepening cooperation? We investigate the institutional design paths of subnational cooperation that are chosen to address increasingly complex and interconnected policy problems. We theorize that besides the substantive problem, earlier choices matter to explain what institutional design mechanism is chosen; that is, the design of existing institutions between two subnational governance units, called substates, influences the design of subsequent institutions. Using a semi-parametric Cox proportional hazards model, we show that the design paths of subnational cooperation in the Swiss water governance sector correlate with earlier design choices. Our results indicate that not all cooperation is self-reinforcing and path-dependent, but they show which specific design choices are more likely to follow each other in repeated formal federal intergovernmental cooperation.     

Discrete Element Analysis of the Minimum Thickness of Oval Masonry Domes

This study focuses on domes the ground plan of which, instead of the more common circular shape, is an oval, and aims at finding the minimally necessary uniform wall thickness for domes of different geometries loaded by their selfweight. The discrete element code 3DEC was applied because of its capability of simulating the collapse mechanisms of masonry structures. Results on the minimal wall thickness, corresponding masonry volume and failure mechanisms for different dome geometries are presented. Three ranges of the friction coefficient were found. For very low frictional resistance collapse happens with pure frictional sliding, for any arbitrarily large wall thickness. In the range of relatively high (i.e., realistic) friction coefficients the structure collapses without any sliding if the wall is not sufficiently thick, and in the observed range of the friction coefficient the necessary wall thickness is nearly insensitive to its value (collapse initiates with hinging cracks only). Between the two domains an intermediate behavior was found: combined cracking and sliding collapse modes occur for insufficient wall thickness, and the minimal thickness strongly depends on the friction coefficient. The critical and transitional friction coefficients separating the failure modes were determined for different eccentricities of the groundplan.     

Human Remains from the Moravian Gravettian: Morphology and Taphonomy of Isolated Elements from the Dolní V stonice II Site

The excavation and palaeoanthropological analysis of the early Upper Palaeolithic site of Dolní V stonice II has yielded a series of incomplete and isolated human remains, comprising cranial vaults, teeth (including a series from an infant), ribs, arm bones, hand phalanges, leg bones, tarsals, metatarsals and pedal phalanges. Morphologically and morphometrically the elements are similar to those from buried individuals at Dolní V stonice I and II and Pavlov I, as well as to other European early Upper Palaeolithic human remains. They differ principally in the high percentage of cortical areas of the distal humerus and femur. The Dolní V stonice 36 infant's teeth may well derive from an undisturbed burial with in situ bone destruction. Geological processes are unlikely to have produced the taphonomic patterns observed, and the preservation and damage patterns of the elements (other than Dolní V stonice 36) suggest that the original bodies were processed by some combination of scavenging agents. Moreover, the original number of burials at Dolní V stonice II may have been greater than the four currently known.     

Exceptional Sovereignty? Guantánamo Bay and the Re‐Colonial Present

Abstract: The US government has presented Guantánamo Bay to the world through the lens of “exceptional sovereignty”. This argument holds that international law does not apply at Guantanamo because while America has “complete authority” over the base “ultimate sovereignty” rests with Cuba. Many accounts rightly critical of the abuses of power taking place at Guantanamo similarly understand it as something wholly abnormal—a literal “non‐place”. But in falling back on this argument both the American position and many of its critics have tended to “black box” what is taking place within the camp. In this paper I suggest that we ditch any sort of critique that says Guantanamo is somehow outside of the law and instead replace this line of argument with a critical history of the deployment of a particular sort of Executive power there. From this perspective, Guantanamo is better understood as a rather more normal part of the current imperial moment and connected up in various ways to American imaginations and materialisations of power. As a way of exploring some of these connections in greater detail, I examine the construction of Guantanamo as a particular sort of social space by drawing upon the accounts of those who have been there: former guards, detainees and their defence lawyers.     

The geochronological potential of isoleucine epimerisation in cassowary and megapode eggshells from archaeological sites

Our research demonstrates that the extent of isoleucine epimerisation (A/I) in fragments of avian eggshells provides geochronological information in archaeological contexts. In the archaeological sequence of Hay Cave, northern Queensland, Australia, there is an excellent correspondence between the A/I values of Australian brush-turkey (Alectura lathami) eggshells (n = 99) and independent geochronological control (n = 16 radiocarbon ages including 4 on eggshell calcite). The A/I values identify three phases of deposition during the Holocene at Hay Cave. In contrast to the Alectura eggshell A/I values, a poor correspondence was observed between the A/I values of cassowary (Casuarius) eggshells from Toé (n = 35) and Kria caves (n = 23) (Ayamaru Plateau, Papua) and the depths from which the specimens were recovered in these stratified sequences. Given coherent archaeofauna trends and radiocarbon chronologies (n = 8 and 2 eggshell calcite radiocarbon ages at Toé and Kria, respectively) with respect to depth, the variable A/I values are not explicable in terms of mixing. Rather, the variability is most likely due to exposure of the eggshells to the high temperatures of campfires. Despite the variability, eggshells with relatively low A/I values amongst specimens recovered from similar depths (and therefore presumably least influenced by high temperatures) exhibit a gradual increase in A/I with respect to depth, as expected in a stratified deposit. From this observation it is suggested that the identification of heated eggshells will increase confidence in geochronological information provided by A/I. These studies illustrate the complications that arise from campfire-induced acceleration of amino acid racemisation and emphasise that although this phenomenon is common, it is not universally encountered in archaeological contexts.     

Strategic Planning as Region Building on the Eastern Periphery of the EU

This article describes how region-building is performed by four strategic planning initiatives in north-eastern Slovakia, highlighting a tension between balanced and concentrated development perspectives in Slovak regional policy. The plans are read as records of an institutionalizing process, the product of which is the creation of a lasting collaborative relationship between actors. If strategic planning could fulfil a mobilizing and integrating function in eastern Slovakia, it would constitute a significant contribution to the successful negotiation of social and economic transformations associated with post-communist structural change and European Union (EU) accession. Region-building is complicated by an over-emphasis on endogenous perspectives among local actors, hindering vertical integration, and an indeterminacy about the scale at which such an integration is best performed.
