Pronounced bilateral asymmetry of the complete upper extremity: a case from the early Neolithic Baikal,Siberia

An adult male skeleton from the early Neolithic cemetery of Shamanka II on the south coast of Lake Baikal (Siberia, Russia) presents one of most striking examples of upper limb bilateral asymmetry documented without obvious indicators of skeletal pathology or trauma to the afflicted arm. The condition is noteworthy not only for its severity, with asymmetry values as high as 89.5%, but also for its involvement of the whole upper extremity, from clavicle to manual phalanges. The lack of any demonstrable hypertrophy on the unaffected left arm, and the clear evidence of extensive hypotrophy/atrophy on the right, leave little doubt that this asymmetry has a pathological or traumatic basis rather than a functional (activity‐induced) one. It most likely reflects paralysis or paresis of the entire right arm resulting from complete brachial palsy incurred prior to the attainment of skeletal maturity in that limb.

The Earliest Naval Ram

Analyses of the Kuyunjik (Kouyunjik) relief and other data suggest Phoenicia probably did not build ships with rams before the Battle of Salamis. A review of Greek literature, iconography, and archaeology suggests the naval ram may have been a Greek invention, appearing at the earliest in the 6th century BC and possibly as late as the 5th century. Its evolution may have led to a shift from laced to pegged mortise-and-tenon joinery in Greek shipbuilding as well as the development of the wineglass-shaped hull and heavier framing. It may also have influenced the development of large-scale bronze-casting in Greece.

Mobilization of ore fluids during Alpine metamorphism: evidence from hydrothermal veins in the Variscan basement of Western Carpathians,Slovakia

Hydrothermal polymetallic veins of the Gemeric unit of the Western Carpathians are oriented coherently with the foliation of their low‐grade Variscan basement host. Early siderite precipitated from homogeneous NaCl‐KCl‐CaCl₂‐H₂O brines with minor CO₂, while immiscible gas–brine mixtures are indicative of the superimposed barite, quartz–tourmaline and quartz–sulphide stages. The high‐salinity aqueous fluid (18–35 wt%) found in all mineralization stages corresponds to formation water modified by interaction with crystalline basement rocks at temperatures between 140 and 300°C. High brominity (around 1000 ppm in average) resulted from evaporation and anhydrite precipitation in a Permo‐Triassic marine basin, and from secondary enrichment by dissolution of organic matter in the marine sediments at diagenetic temperatures. Sulphate depletion reflects thermogenic reduction during infiltration of the formation waters into the Variscan crystalline basement. Crystallization temperatures of the siderite fill (140–300°C) and oxygen isotope ratios of the parental fluids (4–10‰) increase towards the centre of the Gemeric cleavage fan, probably as a consequence of decreasing water/rock ratios in rock‐buffered hydrothermal systems operating during the initial stages of vein evolution. In contrast, buoyant gas–water mixtures, variable salinities and strongly fluctuating P–T parameters in the successive mineralization stages reflect transition from a closed to an open hydrothermal system and mixing of fluids from various sources. Depths of burial were 6–14 km (1.7–4.4 kbar, in a predominantly lithostatic fluid regime) during the siderite and barite sub‐stages of the north‐Gemeric veins, and up to 16 km (1.6–4.5 kbar, in a hydrostatic to lithostatic fluid regime) in the quartz–tourmaline stage of the south‐Gemeric veins. The fluid pressure decreased down to approximately 0.6 kbar during crystallization of sulphides. U‐Pb‐Th, ⁴⁰Ar/³⁹Ar and K/Ar geochronology applied to hydrothermal muscovite–phengite and monazite, as well as cleavage phyllosilicates in the adjacent basement rocks and deformed Permian conglomerates corroborated the opening of hydrothermal veins during Lower Cretaceous thrusting and their rejuvenation during Late Cretaceous sinistral transpressive shearing and extension.     

Geography, Space, and Science: Perspectives from Studies of Migration and Geographical Sorting

For the past four decades a significant subset of geographers have had a strong interest in using scientific methods and tools to answer questions about society and societal change. The scientific endeavor, learning and verifying new knowledge, has been at the heart of this project. Even though the discipline as a whole seems currently less interested in the classic science project, that project continues within geography and is a part of the wider social science community's attempt to provide verifiable and useful knowledge to a wide range of stakeholders. The findings from studies of migration and the life course, and segregation and geographical sorting reemphasize the very real contribution of spatial science to understanding societal change. Recent work on the geography of neighborhoods and mobility with the context of legal contestation goes beyond academic research per se to show the continuing relevance of an informed scientific approach and the contributions of geography beyond narrow disciplinary boundaries.     

A “Caesarian,”“Augustan,” or “Justinian” Worldview of Theoretical and Quantitative Geography?

An evolving world view of theoretical and quantitative geography is presented using an analogy from the development of the ancient Roman and Byzantine Empires between Julius Caesar in the first century BC to Justinian in the sixth century AD. This is used to set the discussion platform for a series of papers presented by participants from the early days of quantitative revolution in geography and its transformation into a robust and relevant spatial science. Current theoretical and quantitative geography needs to be, first, active in developing new ideas and applications, second, to continue to transform its methodology to be more societally relevant and scientifically robust and, third, to actively engage cultural critiques of these processes.

Two New Location Covering Problems: The Partial P-Center Problem and the Partial Set Covering Problem

Two new covering problems are introduced. The partial covering P-center problem minimizes a coverage distance in such a way that a given fraction of the population is covered. The partial set covering problem seeks the minimum number of facilities needed to cover an exogenously specified fraction of the population within a given coverage distance. The problems are formulated as integer linear programming problems. Bisection search algorithms are outlined for the two problems. The search algorithm repeatedly solves a Lagrangian relaxation of the maximal covering problem. Computational results for the Lagrangian relaxation of the maximal covering problem and for the bisection search algorithms are presented on problems with up to 150 nodes.
