Early in the history of schistosomiasis research, children under 5 years of age were known to be infected. Although this problem was recognized over 100 years ago, insufficient action has been taken to address this issue. Under current policy, such infected children only receive their first antiparasitic treatment (praziquantel – PZQ) upon entry into primary school as current mass drug administration programmes typically target school-aged children. For many infected children, they will wait up to 6 years before receiving their first medication and significant schistosomiasis-related morbidity may have already established. This inequity would not be accepted for other diseases. To unveil some of the reasons behind this neglect, it is paramount to understand the intricate historical relationship between schistosomiasis and British Imperial medicine, to underline its lasting influence on today's public health priorities. This review presents a perspective on the historical neglect of paediatric schistosomiasis, focusing on important gaps that persist from the early days after discovery of this parasite. Looking to end this inequity, we address several issues that need to be overcome to move forward towards the lasting success of schistosomiasis control and elimination efforts.

Three prehistoric sites in the Upper Mun River Valley of north-eastern Thailand have provided a detailed chronological succession comprising 12 occupation phases. These represent occupation spanning 2300 years, from initial settlement in the Neolithic (seventeenth century BC) through to the Iron Age, ending in the seventh century AD with the foundation of early states. The precise chronology in place in the Upper Mun River Valley makes it possible to examine changes in social organisation, technology, agriculture and demography against a background of climatic change. In this area the evidence for subsistence has been traditionally drawn from the biological remains recovered from occupation and mortuary contexts. This paper presents the results of carbon isotope analysis to identify and explain changes in subsistence over time and between sites, before comparing the results with two sites of the Sakon Nakhon Basin, located 230km to the north-east, to explore the possibility of regional differences.

In the north Caucasus, collective dance has long been an expression of communal identity and a forum for political dissent. In this article Sufian Zhemukhov and Charles King examine the emergence and transformation of a communal dance form known as adyge jegu (roughly, “Circassian festival“) in the Russian republics of Adygeia, Karachaevo-Cherkesia, and Kabardino-Balkaria. They chart the history of the adyge jegu after 2005, elucidate debates over the meaning of authenticity in contemporary Circassian nationalism, and provide a detailed archaeology of the specific decisions that enabled this cultural artifact to get constructed in one way but not another. While attention typically focuses on elite-driven narratives of border security and terrorism, the adyge jegu highlights grassroots debates over the meaning of right behavior, the boundaries of communal identity, and alternatives to Russianness in either its russkii or rossiiskii varieties.

The substantial literature on mass violence, from ethnic cleansing to civil wars, has paid surprisingly little attention to the largest instance of mass violence in human history: the Holocaust. When political scientists have approached the subject, the trend has been to treat the Holocaust as a single case, comparing it—sometimes controversially—with other instances of genocide such as Rwanda or Cambodia. But historically grounded work on the destruction of European Jewry can help illuminate the microfoundations of violent politics, unpack the relationship between a ubiquitous violence-inducing ideology (antisemitism) and highly variable murder, and recast old questions about the origins and evolution of the Holocaust itself. After reviewing new trends in history-writing, I highlight opportunities for social-scientifically oriented research centered on the interaction of state power, local communities, and violent mobilization in five areas: military occupation, repertoires of violence, alliance politics, genocidal policymaking, and resistance. My conclusion addresses thorny issues of comparison, morality, and memory.

The issue of time remains a crucial one in Lower Illinois Valley archaeology, and key problems remain unresolved. In this paper, new radiocarbon assays and published dates are used to test hypotheses concerning intra-site bluff top mound chronologies, timing and structure of valley settlement, and the emergence of regional symbolic communities during the Middle Woodland period (ca. 50 cal B.C.-cal A.D. 400). We show that within sites Middle Woodland mounds were constructed first on prominent, distal bluff ridges and subsequently in less-visible spaces, though additional dates are needed to fully understand intra-site chronology. Our analyses generally support previous studies suggesting a north-to-south settlement trajectory of the valley, though habitation site dates indicate a more complicated pattern of regional occupation that has yet to be fully explicated. In addition, floodplain regional symbolic communities also emerged along a north-to-south pattern, though not as rapidly as bluff crest mounds. Importantly, results indicate future areas of research necessary to elucidate regional chronology, resettlement of the valley, and community interactions.

The report of the Presidential Commission for the Analysis of the Communist Dictatorship in Romania, issued in December 2006, is the most serious attempt to understand Romania's communist experience ever produced. Coordinated by the American political scientist Vladimir Tismaneanu, the report covers virtually every aspect of communism as a lived system, from the installation of Communist Party officials during the postwar occupation, through the instruments of coercion, to the fate of religious institutions, the economy, national minorities, and education. The release of the report also contributed to a major political crisis, during which the parliament attempted to unseat the president, Traian Basescu, who had lauded the report and officially condemned communism as an illegitimate system. The question now is whether the commission's report will be used as yet another opportunity to reject history or as a way of helping Romanians learn, at last, how to own it.

In the movies, scholarly work is a contact sport. At a conference or during a public presentation, the scholar is always passionate and articulate. He proclaims radically new theses that cause the audience to shout out objections or gasp at his intellectual audacity. Then, he dashes off a masterful proof on the chalkboard or rips open a curtain to reveal a newly discovered dinosaur skeleton. Someone in the back of the lecture hall starts to clap, and soon all his assembled peers break out into raucous applause.

Products formed from reactions of methyl iodide, 1-chloropropane, 1-iodopropane and 1-bromopropane with Na0 treated and untreated NaX and NaY zeolites were studied using solid state 13C NMR and IR spectroscopy. At room temperature, methyl iodide dissociates to form framework methoxy in untreated NaX with no reaction observed in untreated NaY. Upon Na0 treatment, both NaX and NaY reacts with methyl iodide to form framework methoxy, methane and ethane. Longer carbon chain 1-iodo, bromo and chloropropane were also studied. 1-iodopropane undergoes dehalogenation to form framework propoxy while 1-chloropropane and 1-bromopropane undergoes dehalogenation/ dehydrohalogenation to form framework propoxy and propene.

During the solidification of solder joints composed of near-eutectic Sn–Ag–Cu alloys, the Sn phase grows rapidly with a dendritic growth morphology, characterized by copious branching. Notwithstanding the complicated Sn growth topology, the Sn phase demonstrates single crystallographic orientations over large regions. Typical solder ball grid array joints, 900 μm in diameter, are composed of 1 to perhaps 12 different Sn crystallographic domains (Sn grains). When such solder joints are submitted to cyclic thermomechanical strains, the solder joint fatigue process is characterized by the recrystallization of the Sn phase in the higher deformation regions with the production of a much smaller grain size. Grain boundary sliding and diffusion in these recrystallized regions then leads to extensive grain boundary damage and results in fatigue crack initiation and growth along the recrystallized Sn grain boundaries.
