Former Nazi Officers in the Near East: German Military Advisors in Syria, 1949–56

In the early days of the Cold War, Syria was the first Arab country where former officers of the German Wehrmacht played an active role as military advisors. This was due, in part, to the fact that Germany was not burdened by its past political relations to Arab states for, in contrast to the Western powers, Germany which had never had territorial ambitions in the Near East. Even in the very early stages, German advisors contributed considerably to the development of Syria's armed forces and military intelligence. The advisory activities of German experts became even more intensive as a result of increased trade between the two countries; however, in 1956 the political situation in Syria worsened and the country began moving towards the Eastern Bloc putting an end to the non-official activities of German military advisors.     

边疆地理名称与晚清川藏边务——以“川边”、“西康”概念为考察中心

晚清是近代中国边疆政治地理发生巨大变动的转折时期。随着边疆危机日趋深重,晚清时人逐步意识到慎重命名地理名称的重要性。川藏交界区域地理名称的生成、运用,经历了"炉边"、"川疆"、"川边"等名称混用,以"川边"为过渡性名称,到弃用"川边"、强调"西康"名称的过程。地理名称的变更与晚清川藏边务密切相关,特别是对"边"、"藏"界域之争的有力回应。探讨边疆地理名称多歧性、竞争性,则是本文将历史地理学研究与概念史方法相结合的一种尝试。     

Smells like politics: planning and the inconvenient politics of intensive peri‐urban agriculture

Intensive farming is an increasing part of Australian agriculture, including in the multi‐functional landscapes at the edges of Australian cities. The example of intensive “broiler” poultry production reveals the tensions that arise when sites of hyper‐productivity conflict with social change in rural areas. Planning processes for intensive farming in the Australian state of Victoria are predicated on stability and consensus: on assumed static and uncontroversial ideas of agriculture, its place, and the primacy of agricultural productivity. Yet concerns about the industrialisation of agriculture are live political issues at the local level, especially in dynamic peri‐urban locations. This paper explores the emergence of a politics of place outside the bounds of planning consensus through an analysis of planning appeals and associated media relating to planning permits for intensive poultry developments in Victoria over 2011–2016. We highlight tensions that exist in relation to technical planning assessments and categorisations used to assert farming as the orthodox use of rural land, especially when new forms of farming look and feel demonstrably different. Using Mouffe's problematising of the negation of antagonism and Rancière's notion of the risks of a false consensus democracy, we argue that planning processes for intensive farming illustrate critical issues in participatory planning. While ostensibly post‐political decision‐making narrows the politics of place and food systems to decisions about policing the boundaries and buffer distances placed around intensive poultry developments, alternative representations of rural life persist. The certainty offered by code‐based planning does not negate the ongoing (if inconvenient) politics of intensive peri‐urban agriculture.     

Lepidopteris callipteroides,an earliest Triassic seed fern of the Sydney Basin,southeastern Australia

Earliest Triassic shales in the Coal Cliff Sandstone, Caley Formation, Widden Brook Conglomerate and Dooralong Shale (all basal Narrabeen Group) of the Sydney Basin contain a low diversity fossil flora that survived the greatest mass extinction of all time at the Permian-Triassic boundary. Only one species of seed fern is known from this flora and its affinities were unclear until discovery of its reproductive organs and complete large leaves. An ovuliferous reproductive organ, Peltaspermum townrovii sp. nov., can be attributed to the same plant as the leaves because of their identical stomatal apparatus, which is cyclocytic with papillae overhanging the stomatal pit. Polleniferous organs, Permotheca helbyi sp. nov., may have belonged to the same plant, but are only linked by evidence of association on the same bedding plane yielding no other gymnosperms. Pollen masses found within the polleniferous organ include grains identified as Falcisporites australis (de Jersey) Stevens (1981) when found dispersed. The leaves of this plant have long been enigmatic and attributed to ‘Thinnfeldia’ callipteroides or ‘Dicroidium’ callipteroides; however, these genera had very different cuticular structure. Reassessment of the frond architecture of this plant, based on a large, nearcomplete specimen together with information from cuticles and ovuliferous organs, allows reassignment to Lepidopteris callipteroides (Carpentier) comb. nov. The remarkable cuticle thickness, small stomatal size and low stomatal index of these leaves reflect a time of unusually high atmospheric concentrations of carbon dioxide. This plant was an invader of the Sydney Basin from northern Gondwana, spreading southward during the post-apocalyptic earliest Triassic greenhouse.     

Experimental investigation of carbon dioxide trapping due to capillary retention in saline aquifers

Capillary trapping is a physical mechanism by which carbon dioxide (CO₂) is naturally immobilized in the pore spaces of aquifer rocks during geologic carbon sequestration operations, and thus a key aspect of estimating geologic storage potential. Here, we studied capillary trapping of supercritical carbon dioxide (scCO₂), and the effect of initial scCO₂ saturation and flow rate on the storage/trapping potential of Berea sandstone. We performed two‐phase, scCO₂‐brine displacements in two samples, each subject to four sequential drainage–imbibition core‐flooding cycles to quantify end‐point saturations of scCO₂ with the aid of micro‐ and macro‐computed tomography imaging. From these experiments, we found that between 51% and 75% of the initial CO₂ injected can be left behind after the brine injection. We also observed that the initial scCO₂ saturation influenced the residual scCO₂ saturation to a greater extent than the rate of brine injection under the experimental conditions examined. In spite of differences in the experimental conditions tested, as well as those reported in the literature, initial and residual saturations were found to follow a consistent relationship.     

Reaching across: institutional barriers to cross‐ethnic parties in post‐conflict societies and the case of Northern Ireland

This paper investigates the paradox in post‐conflict societies of continued marginality of cross‐ethnic parties despite significant convergence in public attitudes and identities. In so doing, it examines the argument that parties that attempt to reach across the divide are constrained by consocational institutions designed to accommodate rival identities in such environments. The paper explores this puzzle in the context of Northern Ireland, drawing upon qualitative evidence from elite interviews and focus groups collected in 2012 and 2013. It concludes that cross‐community parties operating in the region do encounter formal institutional barriers, but that such barriers only partially explain the phenomenon and an interplay between formal and informal constraints underlies their position of relatively limited electoral success.     

Fluid mixing induced by hydrothermal activity in the ordovician carbonates in Tarim Basin,China

Permian hydrothermal activity in the Tarim Basin may have been responsible for the invasion of hot brines into Ordovician carbonate reservoirs. Studies have been undertaken to explain the origin and geochemical characteristics of the diagenetic fluid present during this hydrothermal event although there is no consensus on it. We present a genetic model resulting from the study of δ¹³C, δ¹⁸O, δ³⁴S, and ⁸⁷Sr/⁸⁶Sr isotope values and fluid inclusions (FIs) from fracture‐ and vug‐filling calcite, saddle dolomite, fluorite, barite, quartz, and anhydrite from Ordovician outcrops in northwest (NW) Tarim Basin and subsurface cores in Central Tarim Basin. The presence of hydrothermal fluid was confirmed by minerals with fluid inclusion homogenization temperatures being >10°C higher than the paleo‐formation burial temperatures both in the NW Tarim and in the Central Tarim areas. The mixing of hot (>200°C), high‐salinity (>24 wt% NaCl), ⁸⁷Sr‐rich (up to 0.7104) hydrothermal fluid with cool (60–100°C), low‐salinity (0 to 3.5 wt% NaCl), also ⁸⁷Sr‐rich (up to 0.7010) meteoric water in the Ordovician unit was supported by the salinity of fluid inclusions, and δ¹³C, δ¹⁸O, and ⁸⁷Sr/⁸⁶Sr isotopic values of the diagenetic minerals. Up‐migrated hydrothermal fluids from the deeper Cambrian strata may have contributed to the hot brine with high sulfate concentrations which promoted thermochemical sulfate reduction (TSR) in the Ordovician, resulting in the formation of ¹²C‐rich (δ¹³C as low as ?13.8‰) calcite and ³⁴S‐rich (δ³⁴S values from 21.4‰ to 29.7‰) H₂S, pyrite, and elemental sulfur. Hydrothermal fluid mixing with fresh water in Ordovician strata in Tarim Basin was facilitated by deep‐seated faults and up‐reaching faults due to the pervasive Permian magmatic activity. Collectively, fluid mixing, hydrothermal dolomitization, TSR, and faulting may have locally dissolved the host carbonates and increased the reservoir porosity and permeability, which has significant implications for hydrocarbon exploration.     

Geography and Global Change Science: Relationships Necessary,Absent, and Possible

Initiated by geoscientists, the growing debate about the Anthropocene, ‘planetary boundaries’ and global ‘tipping points’ is a significant opportunity for geographers to reconfigure two things: one is the internal relationships among their discipline's many and varied perspectives (topical, philosophical, and methodological) on the real; the other the discipline's actual and perceived contributions to important issues in the wider society. Yet, without concerted effort and struggle, the opportunity is likely to be used in a ‘safe’ and rather predictable way by only a sub‐set of human‐environment geographers. The socio‐environmental challenges of a post‐Holocene world invite old narratives about Geography's holistic intellectual contributions to be reprised in the present. These narratives speak well to many geoscientists, social scientists, and decision‐makers outside Geography. However, they risk perpetuating an emaciated conception of reality wherein Earth systems and social systems are seen as knowable and manageable if the ‘right’ ensemble of expertise is achieved. I argue that we need to get out from under the shadow of these long‐standing narratives. Using suggestive examples, I make the case for forms of inquiry across the human‐physical ‘divide’ that eschew ontological monism and that serve to reveal the many legitimate cognitive, moral, and aesthetic framings of Earth present and future. Geography is unusual in that the potential for these forms of inquiry to become normalised is high compared with other subjects. This potential will only be taken advantage of if certain human‐environment geographers unaccustomed to engaging the world of geoscience and environmental policy change their modus operandi.
