Tension is a polysemic term used across South Asia to describe the strains and scrapes of life, like ‘worry’ or ‘stress’ in Euro-American discourse. Yet in the formerly agro-pastoralist and upwardly mobile Gaddi community of Himalayan India, it is used by women with the qualifying ghar ki – ‘household’ – to indicate a deeper disruption to bodily humours, intimate relations, and household materiality. This article takes ghar ki tension, with a particular focus on the layered qualifier ghar, as a window into the precarity of middle-class domestic life as it is experienced in the bodies of the women who pursue it. Rather than focusing on the communicative functions of women's distress within the household, this article looks to the relational, affective, and material ways in which women see their bodies and houses as mutually constituted and disrupted. This approach reveals how women's domestic labour is both a source of dignity and a burden. This burden is experienced in ghar ki tension, in bodily symptoms of overheating, and visits from supernatural beings. This article suggests that ghar ki tension might offer a novel way of looking at distress as the psychic and embodied cost of upward social mobility beyond the Gaddi context.  相似文献

While contemporary philosophers have been content to declare the logical possibilities of sacrifice exhausted, to have finally ‘sacrificed sacrifice,’ for many people around the world the notion of sacrifice – whether religious, secular, or somewhere in between – remains absolutely central to their understanding of themselves, their relations with others, and their place in the world. From religion to economics, and from politics to the environment, sacrificial tropes frequently emerge as key means of mediating and propagating various forms of power, moral discourse, and cultural identity. This paper lays out reasons for retaining sacrifice as an analytical concept within anthropology, and argues for the importance of a renewed focus on the ‘other side of sacrifice’, as a means of understanding better how sacrifice emerges beyond ritual and enters into the full gamut of social life.  相似文献

ABSTRACT

This article focuses on recent French efforts to expand legal regulation of religious symbols to childcare. Controversies over ‘veiled nannies’ serve as points of departure for investigating laïcité – French secularism – through which religion is regulated. The investigation is based on fieldwork among Muslim women in Marseille and on the analysis of legal decisions, official documents, and media. The debates on whether to legislate on religious symbols in the domain of childcare reveal how the line between religion and politics, and private and public is continuously redrawn through state efforts to cultivate and govern (secular) Republican selves. Drawing on Agrama’s [2012a. Questioning Secularism: Islam, Sovereignty and the Rule of Law in Egypt. Chicago, IL: University of Chicago Press] conceptualisation of secularism as a ‘problem-space’, I argue that legal regulation of religious symbols institutionalises a ‘secular suspicion’ at the heart of efforts to imagine and govern French society and its future, a future in which Muslims increasingly find it difficult to imagine themselves.  相似文献

Wof‐Washa forest is one of the few remaining dry Afromontane forests in the central plateau of Ethiopia. Woody species composition, structure and regeneration patterns of this forest were studied to generate information essential for formulating feasible management options for the forest. Vegetation data were collected from 64 quadrats of size 20 m × 20 m, 10 m × 10 m and 5 m × 5 m for tree/shrub, sapling and seedling, respectively, laid systematically along transects. A total of 62 woody species belonging to 54 genera and 40 families were recorded. Rosaceae was the most diverse family with five (12.5%) species followed by Anacardiaceae, Euphorbiaceae and Myrsinaceae with three (7.5%) species each. Tree/shrub, sapling and seedling densities were 699, 1178 and 7618.7 individuals/ha. About 56.7% of the importance value index was contributed by Juniperus procera, Maytenus arbutifolia, Podocarpus falcatus and Ilex mitis. Vegetation classification resulted in five plant communities: Ilex mitis – Maytenus obscura, Galiniera saxifraga – Maesa lanceolata, Juniperus procera – Erica arborea, Podocapus falcatus – Allophylus abyssinicus and Pittosporum viridiflorum – Polycias fulva community types. Regeneration status of all the woody plant species was categorized as ‘Good’ (28%), ‘Fair’ (19%), ‘Poor’ (8%), ‘None’ (40%) and ‘New’ (5%).  相似文献

Drawing on ethnographic fieldwork with physicians and nurses working in two state-funded southern French hospitals, this article explores why and how medical care providers connected their everyday deliberations about patient care to what they considered to be distinctively French forms of medical responsibility. Many healthcare professionals saw French medical morality in opposition to ‘Anglo-Saxon’ discourses of individual autonomy and transactional choice. In contrast to such ‘transactionalism’, they insisted that ‘French’ ethics required limits that transcended particular circumstances. And yet it was difficult for doctors and nurses working in secular and increasingly neoliberal hospitals to argue against individual transactionalism in an overtly moral register, one that might appear religious and paternalist. Through a close look at two different cases – one in assisted reproduction and one in palliative care – I show how the language of folk psychoanalysis provided some health professionals with a way out of this impasse. Care providers used pseudo-psychoanalytic accounts of patient subjectivities to depict individuals as incapable of knowing, let alone ‘owning’ or rationally mastering, themselves. This, in turn, suggests that some aspects of French secularity may be far less Protestant and liberal than contemporary anthropological work tends to assume.  相似文献

In contemporary India, it has become commonplace to hear middle-class people speak of ‘chemicals’ in the environment, in food, and in everyday commodities. Anxieties revolve around the bodily absorption of these ‘chemicals’, and plastic packaging has come under particular scrutiny as a source of such leached substances. Although anthropological studies have highlighted South Asian conceptions of the person as permeable and affected, through the exchange of biomoral substances, by transactions with the environment, humans, and nonhumans, the concern about ‘chemicals’ references a different type of transfer: that of chemotoxic transmission. Such concern foregrounds new anxieties about the permeable body in the contaminated, ecologically damaged world of late modernity. The case of plastic packaging is illustrative of the differences between frameworks of biomoral substance exchange and chemotoxic transmission. In illuminating those differences, this article focuses on public concerns regarding the bodily absorption of ‘chemicals’, why these concerns are compelling as a political ecological critique of capitalist extraction, and the insights they can offer to anthropological research on the permeable body.  相似文献

Scholtz G. in press. A plea for ‘genealogical thinking’ in comparative biology – a rebuttal to the reply of Szucsich, Wirkner, and Pass to my article ‘Deconstructing Morphology’. —Acta Zoologica (Stockholm) 00 : 1–4. Szucsich et al. (in press) claim that – in contrast to my statement – morphological thinking has to be ‘cladistic.’ Based on this premise, they stress the difference between the relationships among states of characters versus those among structures assigned to the same character state as implemented in numerical cladistic reasoning. SEA claim that my approach to the homology concept only deals with the problem of the integration of various character states into the same character, whereas the necessary relationships among structures assigned to the same state are not covered. Based on this distinction, SEA also criticise the application of similarity in my definition of homology. Furthermore, they address the issue of evolutionarily independent units.  相似文献

In marine ecosystems, acquired phototrophs – organisms that obtain their photosynthetic ability by hosting endosymbionts or stealing plastids from their prey – are omnipresent. Such taxa function as intraguild predators yet depend on their prey to periodically obtain chloroplasts. We present a new theory for the effects of acquired phototrophy on community dynamics by analysing a mathematical model of this predator–prey interaction and experimentally verifying its predictions with a laboratory model system. We show that acquired phototrophy stabilises coexistence, but that the nature of this coexistence exhibits a ‘paradox of enrichment’: as light increases, the coexistence between the acquired phototroph and its prey transitions from a stable equilibrium to boom‐bust cycles whose amplitude increases with light availability. In contrast, heterotrophs and mixotrophic acquired phototrophs (that obtain  < 30% of their carbon from photosynthesis) do not exhibit such cycles. This prediction matches field observations, in which only strict ( > 95% of carbon from photosynthesis) acquired phototrophs form blooms.  相似文献

Trans‐equatorial avian migrants tend to breed, moult and migrate – the main energy‐requiring events in their lifecycle – at different times. Little is known about the relationship between wing moult and pre‐migratory fuelling in waders on their non‐breeding grounds, where time is less constrained than during their brief high‐latitude breeding season. We determined age‐related strategies of Wood Sandpipers Tringa glareola to balance the energetic demands of primary moult against pre‐migratory fuelling in southern Africa by analysing body mass and primary moult at first capture of 1721 birds mist‐netted in 1972–96 at waterbodies in Zimbabwe. Adults moulted all their primaries in August–December, but immatures underwent a supplemental moult of varying numbers of outer primaries in December–April, close to departure. We used locally weighted linear regression to estimate trends in Wood Sandpiper body mass from 1 July to 1 May. They maintained low mass from arrival in July–September to February–early March. Adults fuelled from 10 February to 1 May at a mean rate of 0.25 g/day (sd = 0.16). Most adults (98%) began fuelling 10–75 days after completing primary moult. Immatures fuelled from 4 March to 13 April at 0.24 g/day (sd = 0.14). They used varying strategies depending on their condition: a brief gap between moult and fuelling; an overlap of these processes near departure, leading to slower fuelling; or skipping fuelling altogether and staying in southern Africa for a ‘gap year’. Immatures moulting three or five outer primaries fuelled more slowly than post‐moult birds. Immatures moulting four outer primaries started fuelling 3 weeks later but at a higher rate than did post‐moult birds of this group. In post‐moult immatures, the later they ended moult, the later and faster they fuelled. The heaviest adults and immatures using all moult patterns accumulated fuel loads of c. 50% of lean body mass, and could potentially cross 2397–4490 km to reach the Great Rift Valley in one non‐stop flight. Immatures were more flexible in the timing and extent of moult and in the timing and rate of fuelling than adults. This flexibility enables inexperienced Wood Sandpipers to cope with inter‐annual differences in feeding conditions at Africa's ephemeral inland waterbodies.  相似文献

This paper illustrates how cultural logics of desire are being transformed in the context of the global economy refashioning intimate lives. Exploring the experiences of Euro‐American female professionals in Jakarta, it suggests that they become uncomfortably visible as ‘white bodies’; their desirability appears compromised, especially given Orientalist discourses which valorise Asian women's bodies. At the same time, women's position as well‐paid employees generates a contradictory logic of desire: the ‘ego‐boost’ they experience at work may intensify their demands on the masculinity and enlightened views of potential partners, thus rendering Indonesian men, with their perceived bodily effeminacy and ‘traditional values’ unattractive. As one response to the lack of desirability, some women engage in a moral discourse that casts Indonesian women whom they consider ‘bargirls’, as well as the Euro‐American men they attract, as morally deficient. The paper thus provides an alternative perspective on reconfigurations of desire in the context of global gendered mobility.  相似文献

Halyomorpha halys Stål (Hemiptera: Pentatomidae) has recently become a major orchard pest in the Mid‐Atlantic, USA. Large H. halys populations can develop on wild tree hosts adjacent to orchards, posing an ongoing threat to fruit. Adults and nymphs feed on tree fruit, causing economic injury. Understanding the seasonal patterns of nymphal host use among trees at the orchard‐woodland interface may aid the development of integrated pest management strategies for this pest. In laboratory and field experiments, modified versions of published trap designs – ‘Circle’, ‘Hanula’, ‘M&M’ (after Moeed & Meads) traps – were compared for their effectiveness for capturing H. halys nymphs walking up and down tree trunks. In the laboratory, second instars were released at the top and bottom of ailanthus (tree of heaven), Ailanthus altissima (Mill.) Swingle (Simaroubaceae), logs and captures were recorded after 24 h. Circle and M&M traps, respectively, were most effective for capturing nymphs walking up and down. In the field, traps were deployed on ailanthus trees next to apple orchards and captures were recorded weekly from 24 July to 11 September 2013. As in the laboratory, Circle and M&M traps captured the greatest number of upward‐ and downward‐walking nymphs. Hanula traps were least effective in both experiments. In the field, 88% of total captures were of nymphs walking up trees. This was at least partially explained by behavioral assays in the laboratory demonstrating that nymphs exhibited negative gravitaxis and positive phototaxis. Stage‐specific trends in captures of instars walking up during field sampling were observed. These results suggest that trunk traps can be used to address important ecological questions about seasonal patterns of host use by H. halys nymphs.  相似文献

There are two hypotheses to explain the emergence of the technical behaviour: (1) a sudden and fast appearance across the African continent; (2) a long period of emergence and consolidation before it began to spread. We defend this second hypothesis and suggest that the hominid project started around 3 Myr ago, with a ‘biofunctional’ stage. Later than 2.5 Myr, the ‘biomorphotechnical’ stage began (Mode 1), and, at around 1.7 Myr, another stage emerged and developed: the ‘biopotential’ stage (Mode 2). All these stages consist of a two-part process: innovation/emergence, and socialization/generalization of a technical mode.  相似文献

Olive varieties ‘Koroneiki’, ‘Kalamata’, ‘Mastoidis’ and ‘Amigdalolia’ were employed in two experiments for 3 years to assess the effect of temperature on olive pollen germination and tube growth in relation to relative humidity and genotype. Pollen samples were subjected to pre-incubation at 10, 20, 30 or 40 °C in combination with decreased air relative humidity – 80, 40, 30 or 20%, respectively – for 24 h to simulate temperature stress that is observed during pollen dispersal; and subsequently in vitro cultured. In the second experiment, pollen was exposed at 15, 20, 25 and 30 °C for 24 h in vitro to evaluate pollen response in conditions of water and nutrients availability and to determine the optimum pollen germination and tube growth temperatures for each cultivar. The highest pre-incubation temperature treatment (40 °C) prevented pollen germination in ‘Koroneiki’ and ‘Mastoidis’, with the less affected varieties (‘Amigdalolia’ and ‘Kalamata’) having average germination percentages of only 7.6 and 2%, respectively. Pre-incubation at 30 °C had a negative impact on pollen germination in ‘Koroneiki’ (?65%), ‘Kalamata’ (?20%) and ‘Amigdalolia’ (?72%) compared to the control (20 °C). Pollen pre-incubation at 40 °C decreased significantly the pollen tube length in ‘Kalamata’ (?50%) and ‘Amigdalolia’ (?52%). In the second experiment, in vitro pollen germination increased after incubation at 25 °C for ‘Koroneiki’ (+6%), ‘Mastoidis’ (+52%), ‘Kalamata’ (+10%) and ‘Amigdalolia’ (+10%) compared to the control (20 °C). At 30 °C germination percentages for ‘Mastoidis’, ‘Kalamata’ and ‘Amigdalolia’ were 8, 6 and 14% higher, respectively, compared to the control (20 °C). Pollen tube length also increased with incubation temperature for all of the studied cultivars. Based on the cumulative stress response index (CSRI) that was calculated for high temperature stress the varieties were classified: ‘Mastoidis’ and ‘Kalamata’ as tolerant and ‘Koroneiki’ and ‘Amigdalolia’ as intermediate at 30 °C while all studied cultivars were sensitive at 40 °C. The observed strong genotype-differentiated response in high and low temperature stress could be exploited by plant breeders towards producing new tolerant olive varieties.  相似文献

The aim of this study is to dosimetrically characterize a new MRI based polymer gel system and to evaluate its usefulness in clinical practice just in terms of beam profile measurements.Normoxic N-vinylpyrrolidone based polymer gel (VIPET) phantoms were produced and used in order to perform three main sets of experiments: a) dose–response evaluation and reproducibility experiments, b) experiments for the evaluation of sensitivity of dose characteristics on ‘gel manufacture – irradiation’ time interval and c) experiments for the evaluation of sensitivity of dose characteristics on ‘irradiation – MRscanning’ time interval. It has been shown that this gel system can be used in a wide dose-range of 0–60 Gy. It exhibits a linear dose–response in the dose-range of 2–35 Gy. Following the proposed manufacturing method the dose–response characteristics are reproducible. Moreover, it seems that the optimum ‘gel manufacturing – irradiation’ time interval is 1 day. However, a ‘gel manufacturing – irradiation’ time interval up to ~1 week can be safely used. The optimum ‘irradiation – MRscanning’ time interval in terms of dose–response sensitivity and dose resolution can be reliably ranged from 1 day to 3 weeks. Finally, X-ray beam profile gel-measurements were performed and found to be in satisfying agreement with corresponding small sensitive volume ion chamber measurements. VIPET gel dosimeters preserved the spatial integrity of the dose distribution during a time period of 50 days post-irradiation. The studied gel system can be safely used in clinical practice within the practical limitations found and described in this work.  相似文献

Despite the major advances that have occurred in the study of animal behaviour in the 50 years since the publication of Tinbergen's (ZeitschriftfürTierpsychologie, 20, 1963, 410) ‘Aims and Methods’ paper, the framework he outlined still remains the best way we have of guiding and organizing behavioural research. His distinction between four different types of question – adaptation, phylogeny, immediate causal mechanism and development – and his insistence on being clear on what would count as answers to each of them are still as good an introduction to the subject today as they ever were.  相似文献

Signal reliability is a major focus of animal communication research. Aggressive signals are ideal for measuring signal reliability because the signal referent – attack or no attack – can be measured unambiguously. Signals of aggressive intent occur at elevated rates in aggressive contexts, predict subsequent aggression by the signaler, and elicit appropriate responses from receivers. We tested the ‘predictive criterion’ in smooth‐billed anis, Crotophaga ani, by broadcasting one of two playback types (‘ahnee’ calls only or ‘ahnee + hoot’ calls), presenting a taxidermic mount, and observing the animals’ behavior. Based on the hypotheses that ‘hoot’ calls and ‘throat‐inflation’ displays signal aggressive intent, we predicted that they would be associated with attack, and that signaling rate would increase over the time period leading up to an attack. Indeed, both hoots and throat‐inflation displays reliably predicted attack. The second prediction, that signaling rate increases in the time leading up to attack, was strongly supported for throat‐inflation displays, which increased over the pre‐attack period in both treatments. Hoots increased over the pre‐attack period in ahnee playbacks but not in ahnee + hoot playbacks. Hierarchical signaling systems are characterized by early, less‐reliable predictors of attack, and later, more reliable predictors of attack. During both natural and simulated interactions, the more‐reliable throat‐inflation display tended to precede the less‐reliable hoot call, suggesting that this signaling system is not hierarchical. In a comparison of 11 putative signals of aggressive intent in birds, the throat‐inflation display had the second highest mutual information (reduction in uncertainty) among visual signals and non‐passerine signals while hoots had below‐average mutual information. Natural observations indicate that both hoots and throat‐inflation displays occur in the context of aggressive between‐group encounters, and hoots also occur during within‐group interactions. Throat‐inflation displays appear to be reliable indicators of aggressive intent, but the function of hoot calls is less clear.  相似文献

Currently our assessment of whether someone is a good parent depends on the environmental inputs (or lack of such inputs) they give their children. But new genetic intervention technologies, to which we may soon have access, mean that how good a parent is will depend also on the genetic inputs they give their children. Each new piece of available technology threatens to open up another way that we can neglect our children. Our obligations to our children and our susceptibilities to corresponding legal and moral sanctions may be about to explosively increase. In this paper I argue that we should treat conventional neglect and ‘genetic neglect’– failing to use genetic intervention technologies to prevent serious diseases and disabilities – morally consistently. I conclude that in a range of cases parents will have a moral obligation to use genetic treatments to prevent serious disabilities in their children. My particular focus is on prenatal interventions and their impact of the bodily integrity of expectant mothers. I conclude that although bodily integrity constrains moral obligations, it is outweighed in a range of cases.  相似文献

What does it mean to talk of the religion ‘of’ a given country? I reflect on an edited volume dealing with religion in Britain and consider two related themes: the secular considered as ‘absence’ or ‘presence’, and the siting of religion not in conventional denominations or ritual practices but in spaces of encounter between religions, and between the so‐called ‘religious’ and ‘secular’.  相似文献

This paper addresses issues raised in Taylor’s work concerning how communities may come to work in normatively secular ways. For Taylor, it seems to be sufficient for believers (and nonbelievers) to acknowledge that their own ‘construals’ are not shared by everyone. However, this leaves open the question of how the acknowledgement of difference may be turned into respect. A common strategy is to require that faith‐based truth claims are ‘bracketed out’, treating secular and religious discourse as ‘nonoverlapping magisteria’. This secularising strategy is, however, problematic on a number of counts. The article makes a case for a less confrontational, more cosmopolitan conversation between secular and religious reason in a postsecular age, examining in particular the possibilities for conversation between science and mysticism. It concludes that it is possible to retain a commitment to naturalism and yet also accept some of the most mystical of propositions, thereby establishing a bridge between ‘secular’ and ‘religious’ forms of reasoning.  相似文献

Studies on migration and integration in Britain have noted the paucity of research on ‘new’ migrants, especially ‘illegal’ migrants and asylum seekers. This paper focuses on one understudied group – Albanian immigrants and their children – and looks at their migration and settlement, based on sixty interviews conducted in two phases either side of a 2003 mini-amnesty that gave many indefinite leave to remain. This regularization is the fulcrum around which our analytical narrative is built. Focusing on the interaction of migrants' agency with host-country structure, the paper shows that an unsettled asylum policy and delays in implementation have had deleterious effects on migrants' integration and sense of belonging, even after citizenship acquisition. As they search for a social and ethnic positioning within a multi-ethnic host society, the eventual realization of Albanians' migration project is accompanied by culture shock, intergenerational difference and ambivalence towards integration.  相似文献
