This paper presents some of the basic principles of bone fracture physics and outlines characteristics used by forensic anthropologists to distinguish gunshot trauma from blunt trauma. The fracture pattern of a cranium from a historic cemetery in Memphis, Tennessee provides an example of how the mechanism of trauma could be misinterpreted. The pattern of the perimortem fractures is indicative of gunshot trauma with a bullet entering one side of the vault and impacting the opposite side. Identification of radiating fractures, concentric heaving fractures, and observation of the direction of bevel on the fractured surfaces are essential for interpretation of the mechanism that produced the injury.  相似文献

Colgi, Cajal and the Neuron Doctrine   总被引:1,自引:0,他引:1  
Camillo Golgi and Santiago Ramon y Cajal shared the Nobel Prize in 1906 for their work on the histology of the nerve cell, but both held diametrically opposed views about the Neuron Doctrine which emphasizes the structural, functional and developmental singularity of the nerve cell. Golgi's reticularist views remained entrenched and his work on the nervous system did not venture greatly into new territories after its original flowering, which had greater impact than is now commonly credited. Cajal, by contrast, by the time he was awarded the Nobel Prize, was already breaking new ground with a new staining technique in the field of peripheral nerve regeneration, seeing the reconstruction of a severed nerve by sprouting from the proximal stump as another manifestation of the Neuron Doctrine. Paradoxically, identical studies were going on simultaneously in Golgi's laboratory in the hands of Aldo Perroncito, but the findings did not seem to influence Golgi's thinking on the Neuron Doctrine.  相似文献

In Scotland, the shooting industry has a significant impact on the economy, the environment and rural communities. However, styles of land management vary widely, and this is likely to have an effect on the benefits of shooting management. Here we construct a typology of management models, and test its utility in explaining economic benefits. Based on semi-structured interviews with 24 stakeholders representing 28 estates, three management models were defined: ‘Commercial Shooting Estates’ (CSE), ‘Non-commercial Shooting Estates’ (NSE) and ‘Diversified Estates’ (DE). DEs are differentiated from the other models as forestry, farming or biodiversity conservation, rather than shooting, is the main management objective. CSE and NSE are differentiated based on the degree of commercialisation of the shooting: CSEs let almost all of their shooting whereas NSEs do not let any shooting. Were the typology to be applied to a wider, systematic sample of estates, other factors may become more clearly differentiated. We found little variation between the three models in terms of spending and employment directly related to shooting activities. This study presents a typology of shooting management models that can be used to help identify pathways towards a new social contract between Scottish society and its landowners and managers.  相似文献

This viewpoint outlines the likely impact of the election of a Republican government with Donald Trump as President on children, youth and families. It focuses primarily on the impact on undocumented and mixed-status families, and briefly addresses the impacts on children’s health services, juvenile justice and education.  相似文献

Communities living on remote islands are often viewed as among the most exposed and vulnerable to climate change impacts. This study uses the Sustainable Livelihoods Framework to investigate how indigenous communities living on two physically different islands in Torres Strait, Australia, experience what they consider to be the impacts of climate change in relation to their daily lives. During this process, a series of natural, physical, and socio‐cultural limits and barriers to climate change adaptation were identified on Boigu, a low‐lying mud island inundated by the sea during high tides and storm surges. As a volcanic island, Erub's elevation is higher but significant community infrastructure, housing, and cultural sites are located on the low coastal fringe. No immediate limits to climate change adaptation were identified on Erub, but physical and socio‐cultural barriers were revealed. Limits to climate change adaptation occur when adaptation actions fail to protect the things valued by those affected, or few adaptation options are available. Barriers to climate change adaptation may be overcome if recognised and addressed but can become entrenched limits if they are ignored. Within the participating communities, such limits and barriers included (a) restricted adaptation options due to limited access to particular livelihood assets; (b) difficulty engaging with government processes to secure external support; and (c) people's place‐based values, which evoke a reluctance to relocate or retreat.  相似文献

Recent excavations in south‐eastern Wadi ‘Araba in Jordan have revealed the first early Islamic‐period copper‐smelting site known in the eastern side of the valley, which extends south of the Dead Sea to the Gulf of ‘Aqaba. Five test pits were excavated in 2012 at Khirbat al–Mana‘iyya, a prominent copper‐smelting camp in south‐eastern Wadi ‘Araba, Jordan. The results of these excavations demonstrate that the site was primarily active in the seventh–ninth century AD. Its distance from the copper sources of south‐west ‘Araba suggests that its location was chosen based on proximity to wood and water resources, rather than copper ore deposits. The discovery that the site dates to the early Islamic period has implications for previous and future work in south‐east ‘Araba. In particular, it challenges the common—until now—view of the region as virtually devoid of settlement during this period.  相似文献

This essay argues that Andean and Spanish agents both brought a spectrum of understandings of land tenure and land use to their colonial interactions. After a critical survey of what is known about practices in the Andes and Iberia prior to conquest, it turns to specific cases of property conflict and entangled definitions in the sixteenth and early seventeenth centuries in the Rimac Valley, Peru. There heterogeneous definitions of both use and tenure often coexisted, either as forms that communities and individuals could shift between depending upon venue or listener, or as multiple hybrid varieties that eventually produced a common language of property. Finally, the case of urban property, new to the indigenous Rimac Valley, is discussed with an eye to the learning curve wherein indigenous homeowners came to an understanding of the meaning of their lots. These cases, taken together, demonstrate that, rather than supplanting or conflicting, indigenous and Spanish agents often constructed an entangled landscape of property relations, at least until Spanish control of the valley became more hegemonic.  相似文献

Marked by the Census Bureau’s closure of the frontier; the symbolic end of American Indian resistance at Wounded Knee and powerful articulations on the ‘winning of the West’ from Frederick Jackson Turner and Buffalo Bill Cody, the early 1890s was a critical moment in the history of the American West. It also saw the death of one of the region’s most famous cavalry horses, Comanche, who succumbed to colic in 1891 aged twenty-nine. Famously billed as ‘the only living thing to survive the Battle of the Little Bighorn’, this article uses Comanche as a locus around which to examine the history of warhorses in the military culture of the American West, and, more broadly, to point towards a growing scholarship on war and the environment that emphasises the usefulness of such themes as spatiality and inter-species exchange in embellishing our understanding of the experience, impact and cultural memory of war. Not only does Comanche’s lifespan (c.1862–1891) usefully coincide with the federal government’s final conquest of the West but his equine biography serves as valuable testament to the use of horses in the US military as both practical and symbolic agents of American expansionism.  相似文献
