In Puerto Limón, Costa Rica, a small group of artists have established and maintain an aesthetic hierarchy, which distinguishes art from craft, artists from artisans, men from women, elite from philistine. Canvas art is part of a cycle of aesthetic invention, where Limonenses appropriate external resources to fit certain paradigms of legitimacy and permanence. This article explores the arbitrary nature of “fine art” as a category of aesthetic practice, and how the creation of a cultural elite legitimates the production and consumption of art objects.  相似文献

This article explores the potential of industrial ecology to inform the redesign of an existing industry: that which is concerned with the production, sale, and support of automobiles. In so doing, it brings together the concepts embedded in industrial ecology with issues of economic scale, product design or technology, process technology, and the way in which new combinations of these features can result in an alternative structure for the automotive industry that has the potential to enhance sustainability performance. In so doing, the article advances the general argument that the economic, technical, and spatial organization of production and consumption are co-determined in a manner that collectively shapes the industrial ecology of an industry. In contradistinction to the prevailing industry, the article then advances the concept of micro factory retailing as an alternative framework for the industry that would result in significantly different performance in terms of industrial ecology.  相似文献

 Human beings are often able to read a letter or word partly occluded by contaminating ink stains. However, if the stains are completely erased and the occluded areas of the letter are changed to white, we usually have difficulty in reading the letter. In this article I propose a hypothesis explaining why a pattern is easier to recognize when it is occluded by visible objects than by invisible opaque objects. A neural network model is constructed based on this hypothesis. The visual system extracts various visual features from the input pattern and then attempts to recognize it. If the occluding objects are not visible, the visual system will have difficulty in distinguishing which features are relevant to the original pattern and which are newly generated by the occlusion. If the occluding objects are visible, however, the visual system can easily discriminate between relevant and irrelevant features and recognize the occluded pattern correctly. The proposed model is an extended version of the neocognitron model. The activity of the feature-extracting cells whose receptive fields cover the occluding objects is suppressed in an early stage of the hierarchical network. Since the irrelevant features generated by the occlusion are thus eliminated, the model can recognize occluded patterns correctly, provided the occlusion is not so large as to prevent recognition even by human beings.

ABSTRACT

This article departs from the observation that in many living rooms of elderly Kinois (inhabitants of Kinshasa), old and defunctive radio and television sets are put on display. When their primary function, to inform, has been rendered obsolete, we are faced with the question why people continue to display these objects, often next to newer models, in their living rooms. The main argument is that Information and Communication Technologies (ICT) commodities, old and new, defective and repaired, are primarily social objects that are embedded in complex webs of practices and expectations which unsettle the taken-for-granted associations between technology and time. ICT objects are shown to be metonyms of dynamics in social relationships between owners of these ICT goods and others; and, although seemingly paradoxically, these same objects, even when damaged, inhabit promises for a better future. The article thus offers an alternative perspective on electronic modernity, and in particular, the role of Africa therein.  相似文献

The aim of this study was to identify some of the cues that macaques follow when they search for new food sites. A social group of 37 long-tailed macaques was confined to a holding cage while an experimenter concealed food in an outdoor enclosure according to one of the following rules: (1) along the edge of a visible environmental border, (2) within structures of the same general type, or (3) along an ecologically irrelevant, invisible straight line. To provide the animals with a cue for detecting the rule, three piles of visible food were also presented according to the rule. Each of the 60 trials involved a different location in the 880 m2 enclosure. The animals showed clear evidence of utilizing the first two rules from the outset of testing and the third rule about five trials. The animals found concealed food along environmental borders and within matching objects more quickly than along invisible lines. They also showed a rapid improvement in food finding on the invisible line. The results suggest that long-tailed macaques extend their search for food to a given class of environmental structure rather than exclusively by pure spatial gradients. © 1996 Wiley-Liss, Inc.  相似文献

The role of social valuables in establishing and defeating hierarchies in prestate societies is explored through the use of Annette Weiner's concept of "inalienable possessions." Inalienable possessions are objects made to be kept (not exchanged), have symbolic and economic power that cannot be transferred, and are often used to authenticate the ritual authority of corporate groups. Ethnographic examples from Zuni are used to understand the range of individually and collectively owned inalienable objects in Pueblo societies. I then use three classes of these objects from archaeological contexts to gain insight into the history of collective prestige structures in the Southwest. I argue that inalienable goods are more useful than shape prestige goods for understanding the role of social valuables in many nonstate societies, especially those in which inequalities are based on ritual knowledge.  相似文献

This article proposes a multidisciplinary and systemic approach to sustainable consumption that combines environmental considerations of energy usage from a life cycle perspective with a social understanding of consumption grounded in economic anthropology. The goal is to understand both consumption patterns and drivers, with a focus on household energy used for cooling in the metropolitan region of Manila in the Philippines. For different socioeconomic groups, cooling devices also deliver social and cultural services, such as socializing or adhering to Western fashion trends. This article argues for the need to address these aspects if reductions in household energy usage are to become possible. The limits of individual‐choice theories are rendered apparent, with examples of how institutional and structural conditions lock in consumption patterns and restrict household choices. The notion that emerging economies might be able to “leapfrog” over the environmental errors of more industrialized countries is also raised and critiqued.  相似文献

Perceiving faces is critical for social interaction. Evidence suggests that different neural pathways may be responsible for processing face identity and expression information. By using functional magnetic resonance imaging (fMRI), we measured brain responses when observers viewed neutral, fearful, and scrambled faces, either visible or rendered invisible through interocular suppression. The right fusiform face area (FFA), the right superior temporal sulcus (STS), and the amygdala responded strongly to visible faces. However, when face images became invisible, activity in FFA to both neutral and fearful faces was much reduced, although still measurable; activity in the STS was robust only to invisible fearful faces but not to neutral faces. Activity in the amygdala was equally strong in both the visible and invisible conditions to fearful faces but much weaker in the invisible condition for the neutral faces. In the invisible condition, amygdala activity was highly correlated with that of the STS but not with FFA. The results in the invisible condition support the existence of dissociable neural systems specialized for processing facial identity and expression information. When images are invisible, cortical responses may reflect primarily feed-forward visual-information processing and thus allow us to reveal the distinct functions of FFA and STS.  相似文献

Economic intensification has been documented in a diversity of small-scale societies. The existing archaeological theory concerning such intensification has tended to privilege economic and political explanations and largely ignores social action and ritual performance as motivations for economic change. In this article, 1 use both ethnographic and archaeological data to argue that ceremonial feasting and the need for socially valued goods, which are critical for ritual performance and necessary for a variety of social transactions, create the demand that underwrites and sustains economic intensification in small-scale societies. Food for large-scale feasts is acquired through the intensification of food production and procurement targeted specifically for feasting, rather than from the surplus available from routine subsistence production. Large-scale demands for socially valued goods tend to result in specialization on the production of "extraordinary" material culture, which is characterized by two modes of circulation, in networks of social obligations or as offerings in sacred locations.

This article considers the nationalizing practices of everyday life among Palestinian refugees in Jordan. Concerned with what some scholars call banal or everyday nationhood, it examines how particular objects within the ordinary lives of Palestinian refugees articulate conceptions of national belonging and difference. Attending to the discursive and the material, this article argues that understanding Palestinian national practice among refugees in Jordan requires specific attention to the material objects consumed and displayed within the homes and institutions of Palestinian life. As icons productive of a national sensorium, these objects are critical for understanding the constitution of nationhood and what I call a national visualscape. Embedded within the routine spaces of ordinary life, this paper argues that national practice is often visible yet unseen, articulated yet unheard. Palestinian nationhood in Jordan is thus an ordinary affair; it is the practical accomplishment of ordinary people engaged in the production of nationhood without a nationalist movement.  相似文献

In his book, Art and agency , Alfred Gell presents a theory of art based neither on aesthetics nor on visual communication. Art is defined by the distinctive function it performs in advancing social relationships through 'the abduction of agency'. Art objects are indexes of the artist's or model's agency. This article examines Gell's use of agency, particularly in relation to the ritual art that is central to his argument. Focusing on Gell's employment of Peirce's term 'index' (out of his triad of index, icon, and symbol), I note that Peirce's approach deflects attention from signification towards the link between art works and the things to which they refer. I consider what Peirce meant by abduction, and conclude that while Gell makes a good case for the agency of art objects he does not explain the distinctive ways in which art objects extend their maker's or user's agency. Gell lacked the time to make detailed revisions before publication and I acknowledge that, given more time, he might have revised some parts of the book.  相似文献

It is widely assumed that it is ethical to conduct research with human subjects only if the research has social value. There are two standard arguments for this view. The allocation argument claims that public funds should not be devoted to research that lacks social value. The exploitation avoidance argument claims that subjects are exploited if research has no social value. The primary purpose of this article is to argue that these arguments do not succeed. The allocation argument has little relevance to commercial research. Social value is not necessary to avoid exploitation if subjects benefit from participation. Although the standard arguments for a social value requirement do not succeed, that view might be justified in a different way. It might be justified by appeal to the importance of social trust or the integrity of physician investigators. It is possible but doubtful that these arguments succeed.  相似文献

There is ample evidence to show that many types of visual information, including emotional information, could be processed in the absence of visual awareness. For example, it has been shown that masked subliminal facial expressions can induce priming and adaptation effects. However, stimulus made invisible in different ways could be processed to different extent and have differential effects. In this study, we adopted a flanker type behavioral method to investigate whether a flanker rendered invisible through Continuous Flash Suppression (CFS) could induce a congruency effect on the discrimination of a visible target. Specifically, during the experiment, participants judged the expression (either happy or fearful) of a visible face in the presence of a nearby invisible face (with happy or fearful expression). Results show that participants were slower and less accurate in discriminating the expression of the visible face when the expression of the invisible flanker face was incongruent. Thus, facial expression information rendered invisible with CFS and presented a different spatial location could enhance or interfere with consciously processed facial expression information.  相似文献

When a human being comes into existence is crucial in bioethics. Conceptionism is the view that a human being comes into existence at conception. The twinning argument is an influential objection to this view. All versions of the twinning argument rely on a metaphysics of material objects, namely, endurantism. Given this, a strategy for defending conceptionism against the twinning argument is to deny endurantism and adopt an alternative metaphysics of material objects. A version of this strategy which has been debated in this journal is to adopt perdurantism, or the ‘multiple occupancy view’, on which monozygotic twins share the zygote region as a temporal part. We present a novel version of this strategy: conceptionists can evade the twinning argument by adopting an exdurantist metaphysics of material objects. We suggest reasons for thinking that this is a plausible and, indeed, preferable way for conceptionists to avoid the twinning argument.  相似文献

In a recent article in this journal Jonathan Pugh critiques the idea of intermediate ‘moral respect’ which some say is owed to embryos. This concept is inherent within the ‘principle of proportionality’, the principle that destructive research on embryos is permissable only if the research serves an important purpose. Pugh poses two specific questions to proponents of the idea of intermediate moral respect. This article argues that while the questions posed by Pugh are certainly pertinent to the debate, the hypothetical responses he suggests to these questions do not quite get to the core of what is troublesome about the concept. The article suggests alternative responses to Pugh's questions in order to focus attention on more fundamental problems facing the idea of intermediate moral respect, while also pointing to how the intermediate moral respect proponent might best develop these responses. It goes on to argue that these hypothetical responses fail to answer convincingly the questions posed. More specifically, this article challenges two possible justifications for the distinct idea of intermediate moral respect, namely the argument from potentiality (the argument raised by Pugh) and an argument from the proportionality of fundamental moral status (not considered by Pugh). The article also raises a dilemma inherent in the application of the principle of proportionality to cases involving beings to which intermediate moral respect is owed even where it is allowed, ex hypothesi, that both the category of intermediate moral respect and the general proportionality reasoning underpinning the principle of proportionality are basically cogent. This article thus develops and adds to the challenge laid down by Pugh to proponents of the idea of intermediate moral respect.  相似文献

The aim of this article is to quantify the drivers for the changes in raw material consumption (domestic material consumption expressed in the form of all materials extracted and used in the production phase) in terms of technology, which refers to the concept of sustainable production; the product structure of final demand, which refers to the concept of sustainable consumption; and the volume of final demand, which is related to economic growth. We also aim to determine to what extent the technological development and a shift in product structure of the final demand compensate for the growth in final consumption volume. Therefore, we apply structural decomposition analysis (SDA) to the change in raw material consumption (RMC) of the Czech Republic between 2000 and 2007. To present the study in a broader context, we also show other material flow indicators for the Czech Republic for 2000 and 2007. Our findings of SDA show that final demand structure has a very limited effect on the change in material flows. The rapid change in final demand volume was not compensated for crude oil, metal ores, construction materials, food crops, and timber. For the material category of non‐iron metal ores, even the change in technology contributes to an increase in material flows. The largest relative increases are reported for non‐iron metal ores (38%) and construction materials (30%). The main changes in material flows related to the Czech Republic are driven by exports and enabled by imports, the main source of these increased material flows. This emphasizes the increasing role of international trade.  相似文献

This article examines the selective use of plant materials in design in Melanesia. It explores – through an analysis of pandanus leaf mats in New Ireland, Papua New Guinea – how makers select fibres on the basis of their capacity to express social relations to varying temporalities before their natural decay. J.J. Gibson's theory of affordance and Donald Norman's concept of mapping are critically applied for this purpose. This approach emphasizes how social and temporal relations are condensed into objects, and refocuses anthropological attention towards materials and their affordances in the production of material culture.  相似文献

When analyzing the metabolism of our economy, the usual choice for a measure of resource consumption is the throughput of matter and energy. This, however, cannot be sufficient, since consumption by definition is always relating to the destruction or transformation, and hence a change in quality, not only in quantity, of material or energy flows. Here, an approach is presented that takes the entropy production associated with any process as a measure for the resource consumption of that process. Entropy production is thereby used to approximate the intuitive notion of consumption, which can best be described by the term loss of potential utility. This article delivers theoretical evidence for the validity of this choice, and a second article in a future issue will present an application taken from the metallurgical sector. The related concept of exergy analysis is discussed and compared against the entropy approach.  相似文献

This article explores representations of Mexican Zapotec textiles as texts and as sites of contested values and meanings. Discussion of this indigenous cottage industry begins in the Oaxacan village of Teotitlán del Valle, the site of production, and follows the textile as it moves across social and cultural borders as a commodity in postindustrial consumer culture. The anthropologist's mediating role in brokering Zapotec textiles is considered within the social context of exchange relations between buyer and seller. Ethnographic stories about the production and aesthetics of Zapotec textiles are contrasted with consumers’ self-fashioning narratives of embodied experiences associated with their hand-woven possessions. The article concludes with reflections on the narrative threads of text that comprise a Zapotec textile's intrinsic value as both art and craft.  相似文献

We examined object permanence in black‐and‐white‐ruffed lemurs (Varecia variegata) at Zoo Atlanta. A series of visible and invisible displacement tasks with suitable controls were presented to five adult subjects. Subjects performed significantly above chance on all regular tasks, except for the double invisible displacements. Subjects failed visible and invisible controls. Failure on the control trials did not appear to be because subjects used the “last box touched” strategy (subjects did not choose the last box touched significantly more than expected by chance). However, a substantial percentage of choices was made to the last box touched by the experimenter. There was no significant difference between this percentage, and the percentage of choices made to the baited box (on both visible and invisible controls), which indicates that subjects were drawn to both boxes which the experimenter visited/touched, and thus failed the controls. Based on the results from the present study, we believe that there is no evidence that black‐and‐white ruffed lemurs understand visible and invisible tasks in the traditional object permanence battery.
