The medical, legal, and lay communities utilize a range of words to describe a pregnancy that does not result in live birth. These terms, including abortion, miscarriage, and stillbirth, are more than just words: they carry with them a range of meanings and social consequences. This paper explores the complex implications embodied in the language used to designate fetal death and describes how they simultaneously, and paradoxically, establish conflicting subject positions for mother and fetus. It also examines the statutory regulations that affirm the problematic terms in a manner that may leave grieving families without ritual outlets for the expression of their loss. This paper draws on specific examples from Aotearoa New Zealand, while recognizing similarities across Western cultures. 相似文献

The increasing interest in the human microbiota raises some interesting questions about the terminology we use to describe some of the structures and strategies employed by commensal and pathogenic microbes to compete in these complex biological ecosystems. For example, all microbes arriving in the alimentary tract face the task of surviving passage through the stomach, coping with bile, interacting with the immune system, competing with the established microbiota, and obtaining sufficient nutrients to gain a foothold in this hostile environment. It is not surprising then that many gastrointestinal microbes (both pathogens and commensals) use similar strategies to overcome the challenges associated with this particular biological niche. Given that many of these structures and strategies were discovered and characterized in pathogens and because they often play important roles in establishing and maintaining an infection, they have often been characterized as virulence factors. It would be misleading to describe the same strategies and structures found in harmless commensals as “virulence factors,” since they represent a sine qua non for life in the gastrointestinal tract. It may be time to reconsider and refer to them as “niche factors,” both in terms of providing scientific accuracy but also in light of the growing interest in using gut microbes as probiotics, where the distinction between virulence factors and niche factors is likely to be very important from a regulatory perspective. 相似文献

The names of organisms have major impacts on the geopolitical world. The current state of flux in the taxonomy of the genera Cryptosporidium and Giardia illustrates the effects that names can have on environmental and governmental policy. Taxonomy remains a vital science that is very much alive in the application of modern methods for describing morphologically cryptic species. 相似文献

The complete sequence of rice centromere 8 reveals a small amount of centromere-specific satellite sequence in blocks interrupted by retrotransposons and other repetitive DNA, in an arrangement that is strikingly similar in overall size and content to other centromeres of multicellular eukaryotes. 相似文献

Have you ever wondered why professionals have so many complicated names for things? Two reasons come to mind: efficient communication, but also 'show'. Connecting with a wider audience means learning to tread the fine line between perfect accuracy and being understood. 相似文献

This article concerns the photographic collection of Paka anak Otor, the Bidayuh owner of a ‘mini-museum’ in Sarawak, Malaysian Borneo, and how it became entangled in his claims to status within and beyond his village. Superficially, the situation is easily apprehended via two analogous approaches within photographic theory and Southeast Asianist ethnography, which treat objects and images as representations or bearers of power and meaning. Here I suggest that such approaches end up eliding the action-centred nature of Paka's ‘big name’-making ambitions. In response, I approach his photographic collection through an analytical framework deriving from Alfred Gell's seminal theory, Art and Agency (1998), which has hitherto remained marginal to Southeast Asianist anthropology. I argue that, more than merely symbolising or bearing his ‘big name’, Paka's photographs were agentive image-objects that actively instantiated it. I conclude by asking how such an analytical shift might encourage a reconceptualisation of ‘power’ and ‘objecthood’ in Southeast Asianist anthropology. 相似文献

The pfam04002 annotation describes RadC as a bacterial DNA repair protein. Although the radC gene is expressed specifically during competence for genetic transformation in Streptococcus pneumoniae, we report that radC mutants exhibit normal uptake and processing of transforming DNA. They also display normal sensitivity to DNA-damaging agents, providing no support for the rad epithet. 相似文献
