A complex Neolithic economy: isotope evidence for the circulation of cattle and sheep in the TRB of western Sweden

We report here the results of strontium, oxygen and carbon isotope analysis of teeth from domestic animals at two Neolithic settlement sites in Falbygden, Sweden. The main result is the high mobility of domestic animals, particularly of cattle but also of sheep. More than half of the analysed cattle teeth show strontium isotope signals indicating that they were raised in an area of Precambrian rock, outside the sedimentary Cambro-Silurian rocks found in Falbygden. This is in marked contrast to pigs, which were mostly local to Falbygden. The mobility of cattle is much higher than that of humans, for which the frequency of immigrants is about 25%.     

Wales: Industrial Fallibility and Spirit of Place

Barely noticed in their anonymity and detachment, the mining communities of South Wales are being left isolated through the locational forces of deindustrialization. These monuments to an era of past industrial grandeur now harbor a dispirited people who reflect a growing passivity to their plight, a saturnine resignation to their distress. The collapse of their cultural spirit can indicate what might be expected to occur in other declining industrial areas of Europe and the United States where communities also experience industrial fallibility.     

Mitchell's Influence on European Studies of Peripheral Nerve Injuries During World War I

Objective: Describe the influence of S. Weir Mitchell's (1829-1914) work, and in particular his ideas on causalgia, on European physicians who treated peripheral nerve injuries during World War I (WWI). Background: During the American Civil War (1861-1865), Mitchell studied peripheral nerve injuries with colleagues George Read Morehouse and William Williams Keen. Three monographs resulted from this work. All were important landmarks in the evolution of knowledge of peripheral nerve injuries. A subsequent occasion to improve knowledge came in WWI. Methods: The most important European monographs or series on peripheral nerve injuries from WWI were studied with special interest in references to causalgia and Mitchell's works on peripheral nerve injuries. We included works by Tinel, Athanassio-Bénisty, Purves-Stewart & Evans and Carter, Foerster and Oppenheim. Results: Tinel and Athanassio-Bénisty provided the most detailed information on peripheral nerve injuries and causalgia and often referred to Mitchell. Both mentioned a possible sympathetic origin. Athanassio-Bénisty described tremor and other movement disorders in relation to causalgia. Purves-Stewart and Evans mentioned Mitchell and causalgia in the second edition of their book. They advocated the term "thermalgia." Carter, who had access to data of many cases, concentrated his work on causalgia, referring to Mitchell. Foerster provided data of a great number of peripheral nerve injuries, but did not refer to Mitchell. However, he described the symptoms of causalgia cursorily, applying the term Reflexschmerz (reflexpain). Oppenheim was particularly interested in muscle innervation and referred to Mitchell with respect to hypertrichosis and glossy skin. Oppenheim did not use the term causalgia, although he described the syndrome in some of his patients. It wasn't until around 1920 that German physicians devoted significant attention to causalgia and began using the term. Conclusion: Knowledge of peripheral nerve injuries was greatly advanced during and after WWI. Mitchell's influence was mainly found in the French medical literature, where his findings provided the basis for further research on the origin of causalgia. In England, Mitchell and causalgia were also well-known. We found evidence to suggest that some of the English knowledge came from French physicians. German physicians described the symptoms of causalgia, but did not use the term, nor did they refer to Mitchell. This variation in Mitchell's influence by country probably reflects the fact that Mitchell's Injuries of nerves and their consequences was translated into French but not German.     

UNDERSTANDING THE UNIQUE IMPACTS OF ECONOMIC GROWTH VARIABLES*

ABSTRACT The paper uses a computable general equilibrium (CGE) model for a small city to examine how expansions in export and local sectors, changes in total factor productivity (TFP), and growth in population impact an economy. We examine the effects of each source of growth and find that the level and distribution of economic activity vary considerably. We also evaluate each source of growth in the context of a variety of policy metrics, which provide guidelines to policy makers, including the types of firms to be recruited in specific regions.     

Spatial variation of biologically available strontium isotopes (Sr/Sr) in an archipelagic setting: a case study from the Caribbean

This paper presents the results of strontium (Sr) isotope analysis of modern and archaeological animal remains and modern plant samples from the Caribbean region. The goal is to assess if patterns of human mobility can be determined from the archaeological record in an archipelagic setting. The range of variability and spatial distribution of biologically available strontium isotope signatures is reported and data evaluated to determine if sufficient heterogeneity exists to permit the identification of mobility despite the presence of potentially large contributions of marine strontium in island and coastal ecosystems. The (is)landscape is divided into several sub-regions based on the age and lithology of underlying geology and the variability of ⁸⁷Sr/⁸⁶Sr ratios is reported as; mean ⁸⁷Sr/⁸⁶Sr ± 2 standard deviations, number of samples: 1) Volcanic and Intrusive rocks (0.7077 ± 0.0019; n = 162); 2) Cretaceous–Miocene Limestone (0.7085 ± 0.0009; n = 50); 3) Pliocene–Quaternary Limestone (0.7091 ± 0.0004; n = 54); 4) Sedimentary Deposits (0.7094 ± 0.0015; n = 16); 5) Metamorphic Deposits (0.7104 ± 0.0014; n = 6). There are substantial differences between expected ⁸⁷Sr/⁸⁶Sr values based on associated geology and measured ⁸⁷Sr/⁸⁶Sr in flora and fauna samples. These differences emphasize the importance of focusing on bioavailable strontium, as opposed to geological proxies, for estimations of Sr isotope ranges, especially in archipelagic environments. While some overlap exists between the ⁸⁷Sr/⁸⁶Sr ranges of certain sub-regions, other sub-regions possessed limited variation and could be distinguished based on strontium isotope data. This spatial patterning of biologically available strontium indicates that strontium isotope analyses can be successfully applied to the archaeological study of human mobility within the Caribbean region.
