We present results of particle size and radioactivity analyses of sediment samples collected from five sites with different burial environments. The uranium, thorium and potassium concentrations in the five sample sets are shown to vary with particle size. The potential effects of the observed size-dependent variations on electron spin resonance (ESR) dating of tooth enamel are assessed using two hypothetical models. Our results show that any bias to relatively fine fractions could result in a significant overestimation of the total environmental dose rate, leading to an underestimation of the calculated ESR age.  相似文献

In this article, I examine both the problem of so-called postmodern history as it relates to the Holocaust and suggest the ways that Saul Friedlander's recent work successfully mediates between the somewhat overly polemicized positions of “relativist” and “positivist” history. In this context, I find that in his search for an adequately self-reflexive historical narrative for the Holocaust, Hayden White's proposed notion of “middle-voicedness” may recommend itself more as a process for eyewitness writers than as a style for historians after the fact. From here, I look at the ways Saul Friedlander's reflections on the historian's voice not only mediate between White's notions of the ironic mode and middle-voicedness, but also suggest the basis for an uncanny history in its own right: an anti-redemptory narrative that works through, yet never actually bridges, the gap between a survivor's “deep memory” and historical narrative. For finally, it may be the very idea of “deep memory” and its incompatibility to narrative that constitutes one of the central challenges to Holocaust historiography. What can be done with what Friedlander has termed “deep memory” of the survivor, that which remains essentially unrepresentable? Is it possible to write a history that includes some oblique reference to such deep memory, but which leaves it essentially intact, untouched and thereby deep? In this section, I suggest, after Patrick Hutton, that “What is at issue here is not how history can recover memory, but, rather, what memory will bequeath to history.” That is, what shall we do with the living memory of survivors? How will it enter (or not enter) the historical record? Or to paraphrase Hutton again, “How will the past be remembered as it passes from living memory to history?” Will it always be regarded as so overly laden with pathos as to make it unreliable as documentary evidence? Or is there a place for the understanding of the witness, as subjective and skewed as it may be, for our larger historical understanding of events? In partial answer to these questions, I attempt to extend Friedlander's insights toward a narrow kind of history-telling I call “received history”—a double-stranded narrative that tells a survivor-historian's story and my own relationship to it. Such a narrative would chart not just the life of the survivor-historian itself but also the measurable effect of the tellings—both his telling and mine—on my own life's story. Together, they would compose a received history of the Holocaust and its afterlife in the author's mind—my “vicarious past.”  相似文献

Roller explores the evidence for eunuch priests who castrated themselves to honour the Great Mother Goddess Cybele. While the custom of sacred eunuchism originated in Phrygia (in central Turkey), such priests are best attested in Greek and Roman society, where they were viewed with disgust and loathing because of their asexual condition and because they adopted the dress, hairstyles and mannerisms of women. The negative reactions to the eunuch priest rest on an unspoken assumption of the superiority of masculine appearance and of the inviolability of appropriate gender roles for men and women.  相似文献

Heron and Masthead Islands in the Capricorn Group of the Great Barrier Reef Marine Park support major nesting colonies of the wedge-tailed shearwater. The distribution pattern of shearwater nesting burrows was established for particular habitats on both islands by means of a nearest neighbour analysis. Areas of Pisonia grandis forest had the highest burrow density and near-random distribution patterns for burrows while the island fringes had the lowest densities and higher degrees of aggregation. These results may reflect the importance of social communication within a wedge-tailed shearwater colony. Burrows are distributed in patches around the margins of the colony where clear and fringe habitats are represented, but randomly near the centre in Pisonia areas, where sheer numbers may negate the need for further aggregation.  相似文献
