Civil law rules were adopted in Florida that granted married women property rights long before legal reforms occurred in northern states. This article analyzes white wives' property and law in Florida between 1820 and 1860. Initially, married women's property rights were inadvertently protected by treaty law and limited to women who married before 1818. Wives' right to own separate property in Florida was subsequently reconfirmed in statute and extended to include later marriages. In contrast, nonwhites generally lost the rights and property they had enjoyed under Spain's civil law in the same period. This contrast reveals that in Florida (and other southern borderlands) it was not concern for women, or simply legal precedent, but the desire to incorporate new territory and expand slavery that influenced the development of marital property law. This challenges previous histories, which have excluded the earlier acts in the Southern borderlands and emphasized those passed in the Northeast beginning in the late 1840s. While those later acts were influenced by the early woman's rights movement and by concern for families reduced to poverty during the rise of market capitalism, this case study indicates that expansion of United States territory and slavery were responsible for the earlier married women's property rights in southern borderland territories such as Florida.  相似文献

Cranioplasty is a well‐known procedure in modern neurosurgery. Although some authors have claimed it was also performed by prehistoric trepanners in various parts of the world, there is little hard evidence to support this. Here we review various claims of cranioplasty in Peru, where trepanation was widely practised in Prehispanic times. We find little support for assertions that cranioplasty was common. One recently discovered burial from the Cuzco region, however, provides the first documented case of the reinsertion of a bone plug into a trepanation opening.

This study collects data from three major journals and analyses them in order to assess the recent (1997–2006) nature of the study of palaeopathology within Britain. It considers the types of study published (case, population or method), whether findings are integrated with other data, the particular ‘theme’ that is considered (diet, activity patterns, etc) and the particular pathological condition focused upon (metabolic, dental, etc). The findings show there is a move away from the traditional case study and an increase in the acknowledgement of the value of integrating data with wider information. There is also a bias towards certain ‘themes’ and pathologies, reasons for which are discussed. Copyright © 2009 John Wiley & Sons, Ltd.  相似文献

The aim of this study was to investigate a unique case of polydonty in wild boar from the early medieval Novgorod (second half of 11th century AD). The only preserved distal part of the right mandibular branch shows a rotated transitional permanent extra premolar between P3 and P4. This abnormality has the potential to serve as a territorially‐based indicator of past wild boar populations. Copyright © 2009 John Wiley & Sons, Ltd.  相似文献

The study of ancient DNA (aDNA) using molecular methods is an increasingly valuable tactic in bioarchaeology. While this method must be carefully undertaken to ensure that the molecules detected are representative of the ancient sample and not modern contaminates, there is a danger that a ‘one size fits all’ approach to validation will lead to misinterpretation and/or missed opportunities of valuable findings. When comparing human and pathogen aDNA, there are many shared technical means that can ensure best practice. However, there are a number of assumptions that should not be used for both scenarios. We discuss these aspects in reference to a recent article published by this journal and highlight some of the latest advances in molecular detection of ancient pathogen DNA that can further improve this endeavour.

The paper explores interpretations of two sets of pathological horse vertebrae identified during analyses of animal bones from recent excavations at the castle at Malbork in northern Poland (formerly Marienburg in Prussia). One specimen dates to the 18th century and the other to the medieval period. The castle was initially constructed by the Teutonic Order from the late 13th century and occupied by military institutions into the 19th century, and is one of the largest fortified structures in Europe. The pathological vertebrae are attributed to prolonged load‐bearing. The problematic interpretation of the remains from the medieval context as belonging to a warhorse is discussed. Warhorses are widely described in contemporary documentary sources which indicate that mares were typically kept in farms on the Order's estates in late‐medieval Prussia, while studs were separately stabled at castles. There is not enough data to confirm the medieval specimen as a warhorse, and both vertebrae may simply represent riding animals. Copyright © 2009 John Wiley & Sons, Ltd.  相似文献

The next‐to‐the‐last witness at the July 1968 hearings on the nomination of Abe Fortas to replace Earl Warren as Chief Justice was James Clancy. Along with another attorney, Charles Keating, who would later gain infamy in the savings and loan scandal of the 1980s, Clancy appeared on behalf of Citizens for Decent Literature, an anti‐smut organization that had filed amicus briefs supporting censorship “as essential to the development of good family living” 1 in the Supreme Court's important obscenity decisions. 2 Clancy asserted that everyone should see the materials Fortas had held were entitled to First Amendment protection, and so he had assembled a thirty‐minute compilation of them for the Judiciary Committee's viewing.  相似文献

The practice of historical archaeology has exploded over the past two decades, and especially since 2000. Methodological advances and new theoretical insights mean that archaeological research requires periodic evaluation, and this overview builds on the work of three earlier assessors of the discipline. Here, I concentrate on four areas of research currently being pursued by historical archaeologists: analytical scale, capitalism, social inequality, and heritage and memory. I conclude that historical archaeologists have made major strides in understanding the modern world and that future research promises to offer diverse perspectives that will deepen our appreciation for how the past influences the present.  相似文献
