This paper presents a review of the antiquity of periodontal disease, discussing past aetiological concepts in comparison to current research on the causes of this condition. As periodontal disease is analysable on dry bone specimens, it is possible to document its natural history. To date, little work has been done on an actual system of measurement for periodontal disease in such specimens. A new system of measurement is proposed, which is confined to evaluating the periodontal status of post-mortem skulls. The system is a modification of the Ramfjord index for periodontal disease (PDI) and can be adapted for both individual specimen measurement and for population studies. Seven skulls, ca. AD 500–700, from the Varden Site at Long Point, Ontario, were examined using the proposed system. Mean attachment loss was computed for each of the seven specimens. The results revealed one specimen with early periodontitis, four with moderate periodontitis and two with advanced periodontitis. This system provides a concise method for classification of the severity of periodontal disease in dry bone specimens that will be useful in documenting the history of this disease. 相似文献

Decolonial theorists pose a new challenge to liberation theology: Does its formulation of the option for the poor address the coloniality that distinguishes the modern context? This article argues that an option for the poor within theology, as a decolonial option, has to retrieve and deepen two central concerns of liberation theologians’ early articulation of the option for the poor: (1) the commitment to the poor and the way the divine is manifested historically, and (2) the affirmation of the need for social analysis and the need for this analysis to impact the commitment to God. The article draws on Teología India and womanist theology to indicate how these two interrelated commitments within the option for the poor can strengthen the option for the poor as a decolonial option. 相似文献

The persistent vegetative state (PVS) is one of the most iconic and misunderstood phrases in clinical neuroscience. Coined as a diagnostic category by Scottish neurosurgeon Bryan Jennett and American neurologist Fred Plum in 1972, the phrase “vegetative” first appeared in Aristotle’s treatise On the Soul (circa mid-fourth century BCE). Aristotle influenced neuroscientists of the nineteenth and early-twentieth centuries, Xavier Bichat and Walter Timme, and informed their conceptions of the vegetative nervous system. Plum credits Bichat and Timme in his use of the phrase, thus putting the ancient and modern in dialogue. In addition to exploring Aristotle’s definition of the “vegetative” in the original Greek, we put Aristotle in conversation with his contemporaries—Plato and the Hippocratics—to better apprehend theories of mind and consciousness in antiquity. Utilizing the discipline of reception studies in classics scholarship, we demonstrate the importance of etymology and historical origin when considering modern medical nosology. 相似文献

This article investigates how Gabriele D’Annunzio’s The Triumph of Death brings together Nietzsche’s ideas and Wagner’s music and interweaves them with the motifs of literary Decadence and the author’s own particular sexual politics. The novel is an experimental text striving to be a Gesemtkunstswerk, an integrated work that incorporates music, painting, poetry, regional folklore, and private thoughts about personal and national power. I discuss the novel’s themes of violent sexuality and the anxiety of powerlessness and explore their implications for the fascist political aesthetics in which D’Annunzio played a pioneering role. 相似文献

Scholars of insanity and its historical antecedents have paid very little attention to personal and institutional clothing. Such dress, distributed to patients in mental institutions, has always been inscribed with the conflicting narratives of the period in which it was made and worn. The language of civil and medical authority is more evident than personal choice in the shape and address of the attire. This article examines clothing worn by patients in three Devon mental hospitals during the century before 1960. We consider the ways in which institutional clothing formed part of a hospital regimen of overt control, as well as suiting considerations of economy and employment that figured in these institutions. 相似文献

COLLEGE-TO-WORK MIGRATION OF TECHNOLOGY GRADUATES AND HOLDERS OF DOCTORATES WITHIN THE UNITED STATES 总被引:2,自引:0,他引:2
ABSTRACT. This study estimates a series of random parameter logit models of the college-to-work migration decisions of technology graduates and holders of doctorates within the United States. We employ detailed information on the migration-relevant characteristics of individuals, as well as on their actual origins and destinations at the metropolitan scale. In addition to its obvious implications for "brain drain" policies in U.S. metropolitan areas, the study demonstrates the richness of the random parameters technique for behavioral-geographic analysis. We find that science and technology graduates migrate to better educated places, other things equal; that PhD graduates pay greater attention to amenity characteristics than other degree holders; and that foreign students from some immigrant groups migrate to places where those groups are concentrated. 相似文献

In Canada and elsewhere, there is a growing belief that farming and rural communities have become effectively disconnected from one another. While attention to recent media reporting suggests that incidences of conflict are now as common as examples of support and collaboration, it is suggested that many examples of complementarity remain. These evolving relationships may, however, be linked to the nature of specific farm development trajectories. Such possibilities warrant empirical examination, with attention to known diversity in the family farm sector. This paper reports on an empirical investigation of farm and community linkages in North Huron County, Ontario. The paper builds upon a recent investigation of change in family farming in this region and seeks to document the ways in which local farmers continue to look to their rural communities for support of various kinds. Data are drawn from a survey of farmers in Ashfield and Colborne Townships in 1999. The research explores community linkages around three dominant themes: participation in organisations, purchasing and perceptions and experiences of community support for farming. The findings indicate the persistence of strong linkages between farms and local communities in the study region but point to a potential tendency for disconnection between farms pursuing aggressive expansion and local community organisations and businesses. There is some evidence that jobs and a variety of farm household considerations may form key linkage points between the two sectors, with the importance of these mediated by farm business trajectories and the family life course. 相似文献
