During the 1998 field season, the Western Aleutians Archaeological and Paleobiological Project (WAAPP) team located a cave in the Near Islands, Alaska. Near the entrance of the cave, the team identified work areas and sleeping/sitting areas surrounded by cultural debris and animal bones. Human burials were found in the cave interior. In 2000, with permission from The Aleut Corporation, archaeologists revisited the site. Current research suggests three distinct occupations or uses for this cave. Aleuts buried their dead in shallow graves at the rear of the cave circa 1,200 to 800 years ago. Aleuts used the front of the cave as a temporary hunting camp as early as 390 years ago. Finally, Japanese and American military debris and graffiti reveal that the cave was visited during and after World War II. Russian trappers may have also taken shelter there 150 to 200 years ago. This is the first report of Aleut cave burials west of the Delarof Islands in the central Aleutians. 相似文献

A useful concept that can be invoked to resolve complex bioethical issues is that of moral status (or, human dignity). In this article, we apply this concept to dead human bodies in order to support our view that research on such bodies is permissible. Instead of drawing from salient Western theories of human dignity that account for it by appeals to autonomy or rationality, we will base our investigation on emerging conceptions in African theories of moral status as articulated by Thaddeus Metz and Munamato Chemhuru. Our conclusion is that neither of these theories of moral status, one secular, and the other religious, can accommodate the intuition that we have direct duties of respect towards such bodies because, in relation to Metz's conception, they lack the capacity to enter into social relationships while on Chemhuru's conception, dead bodies appear not to have any meaningful purpose within the hierarchy that captures the ontological systems that determine such status. Consequently, we argue that our analysis provides support for the use of unclaimed cadavers in training and research in medical institutions. 相似文献

This study examines both edible plants and non-food uses of plants in a limited area to provide clues for archaeologists, to interpret their findings including the reconstruction of former diets. The results are based on an ethnoarchaeological study conducted in 1994-1995 on the traditional subsistence economy of a contemporary village, in close proximity to a pre-ceramic Neolithic site, A?ikli, in the Aksaray province of Central Anatolia. As a part of this study, about 600 plant specimens were collected, of which over 300 were considered useful by the villagers. Through this study the floral potential of a limited area, and the richness of the traditional knowledge of plants was documented to provide clues to archaeologists, archaeobotanists, botanists, pharmacologists, economists, and perhaps to the planners of future local development projects. 相似文献

We examine the association between exposure to the market and Western society on the height of adult Tsimane', a foraging-farming society in the Bolivian Amazon. As with other contemporary native peoples, we find little evidence of a significant secular change in height during 1920-1980. Female height bore a positive association with own schooling and fluency in spoken Spanish and with maternal modern human capital (schooling, writing ability, and fluency in spoken Spanish), but male heights bore no association with parental height or with modern human capital. The absence of a secular change likely reflects the persistence of traditional forms of social organization and production that protect health. 相似文献

It is established, that infestation with Gurleya sp. (Microsporidia, Gurleyidae) changes the behaviour of its host Moina macrocopa (Straus, 1820), a crustacean inhabiting pools. Heavily infested host individuals attach to surface film of water before their death by senescence. As a consequence, their dead bodies filled with spores of the parasite adhere to objects dipped in water that probably facilitates the transfer of spores by birds and cattle to other pools. Weakly infested or uninfested individuals drown after the end of their ontogenesis. Distribution of the microsporidian spores by two different ways (with attached dead bodies of the hosts or with bottom sediments) makes invasion of a new host more probable. 相似文献

Autophagy is an evolutionarily conserved catabolic process for maintaining cellular homeostasis during both normal and stress conditions. Metabolic reprogramming in tissues of dead bodies is inevitable due to chronic ischemia and nutrient deprivation, which are well-known features that stimulate autophagy. Currently, it is not fully elucidated whether postmortem autophagy, also known as thanatophagy, occurs in dead bodies is a function of the time of death. In this study, we tested the hypothesis that thanatophagy would increase in proportion to time elapsed since death for tissues collected from cadavers. Brain and heart tissue from corpses at different time intervals after death were analyzed by Western blot. Densitometry analysis demonstrated that thanatophagy occurred in a manner that was dependent on the time of death. The autophagy-associated proteins, LC3 II, p62, Beclin-1 and Atg7, increased in a time-dependent manner in heart tissues. A potent inducer of autophagy, BNIP3, decreased in the heart tissues as time of death increased, whereas the protein levels increased in brain tissues. However, there was no expression of BNIP3 at extended postmortem intervals in both brain and heart samples. Collectively, the present study demonstrates for the first time that thanatophagy occurs in brain and heart tissues of cadavers in a time-dependent manner. Further, our data suggest that cerebral thanatophagy may occur in a Beclin-1- independent manner. This unprecedented study provides potential insight into thanatophagy as a novel method for the estimation of the time of death in criminal investigationsAbstract: Autophagy is an evolutionarily conserved catabolic process for maintaining cellular homeostasis during both normal and stress conditions.

ABSTRACT The term bodyscape encourages thinking about representation of bodies at multiple scales—from different bodies as they move through space to the microlandscape of individual bodily differences. A hegemonic bodyscape's representations tend to idealize and essentialize bodies' differences to reinforce normative ideas about a society's socioeconomic organization. But, a dominant bodyscape is never absolute. Bodyscapes that depart from or subvert hegemonic representations may simultaneously exist. In Western society, the biomedical bodyscape predominates in scientific understandings of bodily difference. Its representation of sex differences conveys heteronormative notions about gender and sexuality. Because the biomedical bodyscape frames studies of ancient bodies, investigators need recognize how their considerations of labor divisions, familial organization, and reproduction may situate modern (hetero)sexist representations deep within antiquity. To innovate analyses of socioeconomic relations, queer theory allows scholars to interrogate human nature. Doing so produces alternative bodyscapes that represent the diversity of past peoples' social and sexual lives.

An important area of biology involves investigating the origins in animals of traits that are thought of as uniquely human. One way that humans appear unique is in the importance they attach to the dead bodies of other humans, particularly those of their close kin, and the rituals that they have developed for burying them. In contrast, most animals appear to show only limited interest in the carcasses or associated remains of dead individuals of their own species. African elephants (Loxodonta africana) are unusual in that they not only give dramatic reactions to the dead bodies of other elephants, but are also reported to systematically investigate elephant bones and tusks that they encounter, and it has sometimes been suggested that they visit the bones of relatives. Here, we use systematic presentations of object arrays to demonstrate that African elephants show higher levels of interest in elephant skulls and ivory than in natural objects or the skulls of other large terrestrial mammals. However, they do not appear to specifically select the skulls of their own relatives for investigation so that visits to dead relatives probably result from a more general attraction to elephant remains. 相似文献

Histopathogenesis of living insects of Myzus persicae Sulzer (Hemiptera: Aphididae) and Phenacoccus manihoti Matile‐Ferrero (Hemiptera: Pseudococcidae) by Beauveria bassiana (Balsamo) Vuillemin (Ascomycota: Hypocreales) was monitored from penetration through insect death. Important events in aphids included fungal penetration of the integument of the less-resistant leg intersegmental membrane and invasion of natural openings, formation of hyphal bodies in live aphids by three days post-inoculation (PI), and extensive hyphal colonization of the two leg segments closest to the insect body at death of the aphids. Confocal microscopy of green fluorescent protein-labeled B. bassiana in live mealybugs indicated the fungus penetrated the host through the legs and mouthparts. The fungus was scarce in live mealybugs at 1–5 days PI, formed hyphal bodies by six days PI, and growth was limited to parts of dead hosts at 6–7 days PI. In dead mealybugs, hyphal bodies were near solid tissue. Blastospores were in the hemolymph. 相似文献

In sub-Saharan Africa, rural–urban relationships are primary arenas in which social change is shaped, expressed, and contested. Like people in many contemporary African societies, rural–urban migrants of the Igbo ethnic group in Nigeria face powerful expectations to be buried "at home" in their ancestral villages and to perform elaborate and expensive funeral ceremonies for their dead relatives. This article argues that Igbo funerals crystallize many of the structural paradoxes associated with inequality in Nigerian society, particularly as they are manifest in kin-based patron–client relations between rural communities and their migrant kin. The tensions that coalesce around burials illustrate how rituals are not only socially integrative but also can reflect, reveal, and contribute to discontents regarding transformations in the organization and extent of social inequality. 相似文献

The endophytic lifestyle has played an important role in the evolution of the morphology of reproductive structures (body) in one of the most problematic groups in fungal classification, the Leotiomycetes (Ascomycota). Mapping fungal morphologies to two groups in the Leiotiomycetes, the Rhytismatales and Hemiphacidiaceae reveals significant divergence in body size, shape and complexity. Mapping ecological roles to these taxa reveals that the groups include endophytic fungi living on leaves and saprobic fungi living on duff or dead wood. Finally, mapping of the morphologies to ecological roles reveals that leaf endophytes produce small, highly reduced fruiting bodies covered with fungal tissue or dead host tissue, while saprobic species produce large and intricate fruiting bodies. Intriguingly, resemblance between asexual conidiomata and sexual ascomata in some leotiomycetes implicates some common developmental pathways for sexual and asexual development in these fungi. 相似文献

A technique for fluorescence staining of X and Y bodies (sex chromatin) after antibody- and complement-mediated cytotoxicity test has been developed. Cytotoxicity was quantitated by staining the dead cells with trypan blue (dye exclusion test). X bodies (Barr bodies) of human female fibroblast (stained with acridine orange) were observed in about 40 percent of the cells which survived cytotoxicity. Y bodies were studied on human male fibroblasts and in a hamster/human hybrid line which retained the human Y chromosome only. Fluorescent Y body was detectable in from 50 to 60 percent of the cells which survived the serological test. The double staining procedure did not significantly affect the proportion of killed (trypan blue-positive) cells. We suggest that this is a useful method for the detection of cytotoxic antibodies against the products of X and Y chromosomes, especially when mixed cell populations-such as tumor, sex chromosome mosaics, sperm, and artificially mixed human male and female cell lines-are tested. 相似文献

This paper analyses how the conceptual and therapeutic formation of Japanese traditional medicine (Kampo) has been socially constructed through interactions with popular interpretations of illness. Taking the example of emotion-related disorders, this paper focuses on the changing meaning of constraint (utsu) in Kampo medicine. Utsu was once a name for one of the most frequently cited emotion-related disorders and pathological concerns during the Edo period. With the spread of Western medicine in the Meiji period, neurasthenia replaced utsu as the dominant emotion-related disorder in Japanese society. As a result, post-Meiji doctors developed other conceptual tools and strategies to respond to these new disease categories, innovations that continue to influence contemporary practitioners. I begin this history by focusing on Wada Tōkaku, a Japanese doctor of the Edo period who developed a unique theory and treatment strategy for utsu. Secondly, I examine. Yomuto Kyūshin and Mori Dōhaku, Kampo doctors of the early twentieth century, who privileged neurasthenia over utsu in their medical practice. The paper concludes with a discussion of the flexibility and complexity of Kampo medicine, how its theory and practices have been influenced by cross-cultural changes in medicine and society, while incorporating the popular experience of illness as well. 相似文献

During the restoration of the main church in Breda (the Netherlands), the city archaeologists rediscovered a tomb with remains
of the ancestors of the Dutch royal family. Research was carried out prior to the reburial of the remains. The combination
of historical, osteological, dendrochronological and 14C data provided names and dates for 7 of the 8 embalmed bodies. The tomb was in use between A.D. 1475 and 1526. Archaeobotanical
results could be compared with several recipes for embalming from the same period. Strikingly many macroremains were found
where mainly pollen was expected. This could mean the bodies were resting on a bed of herbs and spices, but it could also
have been due to the lack of confidence of the embalmers; they may have used all the available aromatics to conceal the smell
of the corpse. At least some of the species were imported from the Mediterranean and/or subtropical regions, but others were
probably locally cultivated.

This paper examines the use of visual images of the Bushman peoples (San) and their cultural objects in contemporary South African advertising. As an image is a site of meaning, the relationship between the people represented in the advertisement and the culture for which the advertisement is produced demonstrates strategies of subjection and power. Within the context of the advertisement, I explore the extent to which San people are appropriated by the consumer society and their ritual objects reduced or altered to a Western aesthetic dimension. The contexts and ideas of the producing society determine production of the visual object. The relationship between the San “artefact” and the advertisement as a work of “art” reflects a dimension of South African social and political processes. Representations of the two juxtaposed societies suggest that the value systems and cultural attitudes of the dominant group present contested domains which are explored. Bushmen represent a malleable signifier which is used to promote an apparently/ ostensibly applied vision of an emerging non‐racial country. 相似文献

In what ways are care and compassion implicated in efforts to establish lives worth living? Drawing on fieldwork in a Danish Neonatal Intensive Care Unit (NICU), in this article we investigate the role of family biographies in conducting life-and-death decisions around premature infants. Guided by a larger literature on citizenship, we view decisions in the NICU as political acts of assigning citizenship. We ask what bodies and biographies can generate and evoke care and compassion among NICU staff and forge entries or exits from the Danish Welfare State. We demonstrate that infants’ origin stories are appointed legitimate forms of suffering in contemporary Danish society and are thus granted an unnoticed form of authority in life-and-death decisions. In this way, we conclude that what comes to constitute a life worth living in the twenty-first-century Danish Welfare State is in fact the worth of the family. 相似文献

Contemporary patterns of morphological variation among populations reflects the interplay between historic and contemporary processes that result from selection and constraint. Using the pumpkinseed (Lepomis gibbosus), a species native to North America and introduced to Europe, we assessed the shared and unique aspects of morphological divergence in lentic and lotic environments among native and non-native populations. Ten native and thirteen non-native pumpkinseed populations were collected between 2003 and 2010 from lakes, rivers and reservoirs within the Iberian Peninsula and east-central North America. Fifteen linear external measurements among homologous landmarks that pertain to body size, fin position and fin size were taken from all sampled individuals. Eleven of these measurements were used to test for morphological differences among populations. Pumpkinseed found in lotic water bodies exhibited a more anterior placement of pectoral and pelvic fins and a deeper caudal peduncle and body than those found in lentic water bodies from the same geographic region. However, pumpkinseed also showed morphological differences between geographic origins: pumpkinseed from native populations exhibit a more posterior placement of pectoral and pelvic fins, a narrower anterior caudal peduncle and a more slender body than pumpkinseed from non-native populations. In addition, unique responses of populations to waterbodies within geographic origins revealed a shift between water body types that was opposite in direction for native and non-native populations. Native populations exhibited shorter and deeper caudal peduncles and deeper bodies in lotic habitats, whereas non-native populations showed longer and slender caudal peduncles and more slender bodies in the same type of habitat. Our study demonstrates that contemporary patterns of morphological variation among native and non-native pumpkinseed populations can be explained by contemporary selection and/or a common plastic developmental response among water bodies, historical effects related to geographic origin and unique responses of populations to habitats within geographic origin, and that the effects of history and the interaction between history and contemporary habitat were larger than contemporary processes in explaining morphological variation at this large spatial scale. 相似文献

Virus yield produced by dead larvae of balsam fir sawfly, Neodiprion abietis (Harris) (Hymenoptera: Diprionidae), that had been infected at four different larval stages (second, third, fourth, or fifth instar) with two virus concentrations (10(5) polyhedral inclusion bodies (PIB) /ml or 10(7) PIB/ml), were analyzed and compared to determine the effects of instar and amount of virus inoculum on virus production. The results indicate that both larval stage and inoculation dosage significantly affect virus yield. On average, each dead larva produced 1.36-12.21 x 10(7) PIB, depending upon larval age and virus concentration of inoculation. Although each dead larva produced more PIB when it was inoculated in the fourth or fifth stage, inoculation of these larvae did not result in the highest virus yield because of low larval mortality. In terms of net virus return, third instars would maximize virus yield when they are inoculated with a virus concentration that can cause 95-100% larval mortality. 相似文献

Historical archaeologists should be leaders in examining the archaeological dimensions of race and racism in the United States. With few exceptions, though, this has not been the case, as most archaeologists have conflated race and ethnicity. American historical archaeologists have a great opportunity to provide new insights to the anthropological investigation of race and racism if they choose to take this course of action, 相似文献
