Techniques of vision: photography, disco and renderings of present perceptions in highland Papua

This article draws on ethnographic and historical materials to interpret several related photographs and ritual images created by Fuyuge-speakers of highland Papua. The images are analysed as techniques of vision. That is, the images are shown to bring forth present perceptions in a timely manner, as evaluated by Fuyuge men and women. It is shown how the representations are informed by distinctive Fuyuge retentions of the past in the present, and extensions of the present in the future. The article suggests that the tendency to 'read' photographic images for their semiotic connotations misses the local perceptions at work in their creation and use. Rather, photographic and ritual images are analogous to the relations of persons that produce them, with their mutually connected temporality.     

Social Relations and the Green Critique of Capitalism in Melanesia

ABSTRACT  In this article, I explore what a critical environmental perspective would look like in Melanesia, where the distinction between nature and culture, and the expectation that science interprets the former in terms of the latter, may not apply. I consider changes in scientific knowledge production and the shift from cultural ecology to political ecology in Melanesian anthropology, including the argument that Melanesians are neither conservationists nor environmentalists. In contrast, I show how people exposed to pollution from the Ok Tedi copper and gold mine in Papua New Guinea mobilize their understandings of difference in a green critique of capitalism. I examine a strategy session of local activists, a public meeting about their campaign against the mine, and a sorcery tribunal. Finally, I suggest that Melanesian ideas about social relations provide a useful ethnographic analogy for thinking about the mobility and short temporal horizons of contemporary capitalism.     

Language and Culture on the North Coast of New Guinea

Statistical analysis of variability in assemblages of material culture obtained at different villages on the North Coast of New Guinea indicates that similarities and differences among these assemblages are most strongly associated with geographic propinquity, irrespective of linguistic affinities. When assemblage similarity is adjusted for the effect of distance, diversity in material culture appears unrelated to the linguistic relationships of these communities. This study shows that similarity in material culture assemblages can mask marked heterogeneity in language. Language, however, is frequently used to index people in Melanesia on the assumption that language is a useful key to their other human characteristics. This analysis does not lend support to this common practice, and it has implications for how prehistoric cultural complexes in Melanesia are defined and interpreted.     

Use of the sago palmMetroxylon warburgii in the Polynesian Island,Rotuma

The manufacture of edible starch products from sago palms of the genus Metroxylon is common to indigenous people throughout Melanesia but is unknown in Polynesia, even in areas where Metroxylon species occur. We here report the use of Metroxylon as a starch source in the isolated Polynesian island of Rotuma. In Rotuma, Metroxylon warburgii (Heim) Beccari grows wild, but is likely the result of an aboriginal introduction from Melanesia. Samoan ethnohistorical accounts indicate that Metroxylon warburgii was introduced to Samoa from Rotuma. Rotuman manufacture of starch from M. warburgii appears to date from pre-European times as indicated by written accounts of early visitors to Rotuma and Rotuman oral histories. We provide details of the process of starch manufacture in Rotuma and speculate on possible means by which this technology was transferred from Melanesia to Rotuma.     

Melanesian origin of Polynesian Y chromosomes

BACKGROUND: Two competing hypotheses for the origins of Polynesians are the 'express-train' model, which supposes a recent and rapid expansion of Polynesian ancestors from Asia/Taiwan via coastal and island Melanesia, and the 'entangled-bank' model, which supposes a long history of cultural and genetic interactions among Southeast Asians, Melanesians and Polynesians. Most genetic data, especially analyses of mitochondrial DNA (mtDNA) variation, support the express-train model, as does linguistic and archaeological evidence. Here, we used Y-chromosome polymorphisms to investigate the origins of Polynesians. RESULTS: We analysed eight single nucleotide polymorphisms (SNPs) and seven short tandem repeat (STR) loci on the Y chromosome in 28 Cook Islanders from Polynesia and 583 males from 17 Melanesian, Asian and Australian populations. We found that all Polynesians belong to just three Y-chromosome haplotypes, as defined by unique event polymorphisms. The major Y haplotype in Polynesians (82% frequency) was restricted to Melanesia and eastern Indonesia and most probably arose in Melanesia. Coalescence analysis of associated Y-STR haplotypes showed evidence of a population expansion in Polynesians, beginning about 2,200 years ago. The other two Polynesian Y haplotypes were widespread in Asia but were also found in Melanesia. CONCLUSIONS: All Polynesian Y chromosomes can be traced back to Melanesia, although some of these Y-chromosome types originated in Asia. Together with other genetic and cultural evidence, we propose a new model of Polynesian origins that we call the 'slow-boat' model: Polynesian ancestors did originate from Asia/Taiwan but did not move rapidly through Melanesia; rather, they interacted with and mixed extensively with Melanesians, leaving behind their genes and incorporating many Melanesian genes before colonising the Pacific.     

A comparison of the incidence of minor nonmetrical cranial variants in Australian aborigines with those of Melanesia and Polynesia

The incidence of 30 minor non-metrical cranial variants in Australian Aborigines discussed in a previous publication is compared with incidence in crania from Melanesia and Polynesia. With the qualification that the sample sizes from Melanesia and Polynesia are rather small, the data indicate that the differences between Australia and Melanesia and Polynesia exceed those between the three areas into which Australia was divided. The area of Australia made up of the Northern Territory and northern Western Australia has more association with Melanesia than Polynesia as expected, while the more southern regions of Australia have more association with Polynesia than Melanesia perhaps by migrations from Asia. Because the southern Australian Aborigines are now largely extinct, it seems difficult to prove this.     

Divine powers and exchange with ‘others’ in Melanesia

Marshall Sahlins described divine king forms for a wide range of societies from Southeast Asia, Africa, and the Pacific, among others. In this article, I document a divine king form among the Fuyuge people of the Papuan highlands, revising my previous understanding of this powerful figure. At the same time, I argue there is an inextricable connection between Sahlins's theory of divine power and Marilyn Strathern's model of Melanesian gift exchange: both operate according to distinct ideas of otherness. The capacity to engage in transaction derives from cosmological sources while evidence of cosmological power is provided by the ability to engage in transactions with others in effective and powerful ways. More generally, I argue that conventional Melanesian figures of big-men, great men, and chiefs are all versions of the alterity of power in related political forms; each instantiates the mutual relations between cosmological and transactional otherness.     

God Is Nothing but Talk: Modernity, Language, and Prayer in a Papua New Guinea Society

This article brings together theories of local modernity and of linguistic ideology to analyze the way the Urapmin of Papua New Guinea have encountered modern linguistic ideology through their Christianization. Against the prevailing anthropological focus on the indigenization of modernity, this article argues the importance of attending to cases in which people grasp the content of modernity on its own terms. Studying this kind of local modernity allows us to model an important kind of contemporary cultural change and discover neglected aspects of modernity as refracted through the experiences of people new to it. Here, an analysis of the Urapmin encounter with modern linguistic ideology reveals that ideology's rootedness in a model that ties meaning to intention and truthfulness and favors the speaker over the listener in the construction of meaning. It is suggested that an awareness of the biases of this ideology can open up new topics in linguistic anthropology. [ modernity, linguistic ideology, religion, Christianity, Melanesia ]     

Ethnography and the Meta-Narratives of Modernity

Current attempts to increase the relevance of sociocultural anthropology encourage anthropologists to engage in the study of modernity. In this discourse dominated by sociologists, the contribution of anthropology is often to reveal cultural diversity in globalization, leading to the notion of multiple modernities. Yet such ethnographic accounts draw upon familiar sociological abstractions such as time-space compression, commodification, individualization, disenchantment, and reenchantment. This article shows how an underlying meta-narrative preempts social scientific argument by making shifts in analytical scales look natural, as in the alleged need to "situate" the particular in "wider" contexts. This analytical procedure undermines what is unique in the ethnographic method-its reflexivity, which gives subjects authority in determining the contexts of their beliefs and practices. Two ethnographic case studies are presented to support this argument, one from Melanesia on current interests in white people, money, and consumption and the other from Africa on born-again Christianity and individuality. The article ends by reflecting not only on the limits of metropolitan meta-narratives in returning relevance to anthropology but also on the contemporary conditions of academic work that undermine the knowledge practices of ethnography and render such meta-narratives plausible.     

Counterparts: Clothing,Value and the Sites of Otherness in Panapompom Ethnographic Encounters

Panapompom people living in the western Louisiade Archipelago of Milne Bay Province, Papua New Guinea, see their clothes as indices of their perceived poverty. ‘Development’ as a valued form of social life appears as images that attach only loosely to the people employing them. They nevertheless hold Panapompom people to account as subjects to a voice and gaze that is located in the imagery they strive to present: their clothes. This predicament strains anthropological approaches to the study of Melanesia that subsist on strict alterity, because native self‐judgments are located ‘at home’ for the ethnographer. In this article, I develop the notion of the counterpart as a means to explore these forms of postcolonial oppression and their implications for the ethnographic encounter.     

The bones affair: indigenous knowledge practices in contact situations seen from an Amazonian case

This article explores the relation between beliefs and practices manifest in the interaction between indigenous people and outsiders in contact situations. Drawing on oral history, myth, and written documentation, it seeks to reconstruct the experience of the Parakanã, a Tupi–speaking people of Southeastern Amazonia, in their early stable contact with national society. It focuses on some apparently implausible events in order to address the question of how certain beliefs about the nature of the whites were put into action during the contact process. The article also employs historical data from South America and comparative ethnography from Melanesia to suggest new perspectives on the Sahlins–Obeyesekere debate, making use of the Peircian notion of abduction to account simultaneously for the flexibility and the resilience of magico–religious ideas.     

Who Sees What in Pororan Marriage Exchange?

Over time, anthropologists working in Melanesia have provided increasingly nuanced analyses of exchange and, specifically, of the transformation of ‘objects’ and ‘images’ that people perceive in the course of particular revelatory sequences. One aspect of the complexity of exchange in Melanesia appears to have become sidelined, however, by a predominant interest in the temporal transformation of objects and images. This is the multiplicity of objects, images and sequences of their transformation that different participants perceive in the same sequence of events. The primary aim of this paper is to demonstrate this aspect of exchange ethnographically, and to discuss some of its implications on Pororan Island in Bougainville, Papua New Guinea.     

Getting ready for the marriage market? The association between divorce risks and investments in attractive body mass among married Europeans

This article explores to what extent married middle-aged individuals in Europe are governed by the risk of experiencing divorce, when shaping their physical appearance. The main result is that divorce risks, proxied by national divorce rates, are negatively connected to body mass index (BMI) among married individuals but unrelated to BMI among singles. Hence, it seems that married people in societies where divorce risks are high are more inclined to invest in their outer appearance. One interpretation is that high divorce rates make married people prepare for a potential divorce and future return to the marriage market.     

Do hookworms elicit protective immunity in man?

The two main species of human hookworm, Ancylostoma duodenale and Necator americanus (Table 1), are together believed to infect about 900 million people - mainly in tropical countries where adequate sanitary facilities may be lacking. But interactions between the two species, and their relative contributions to observed age-related infection patterns and seasonal cycles of transmission, continue to engender controversy. People tend to remain susceptible to infection through-out life, even with constant exposure to the infective stages. So what role does human immunity or resistance play in the epidemiology and control of infection? In this article, Jerzy Behnke reviews the epidemiology of hookworm infection in the light of current understanding of mechanisms involved in host responses to infection and hookworm evasion of those responses. As he stresses, much further work is required.     

Scale-up engineering in animal cell technology: Part II

In the first part of this article we defined what is meant by scale-up. We also introduced the idea that engineers, in seeking to scale up bioprocesses, look at parameters that limit that process. If the parameters are independent of scale or reactor configuration they may enable the calculation of engineering data to predict behavior at large scales. In this exercise, dimensional analysis is one of the engineer's most important tools.In Part II, we will examine the application of the approach outlined in Part I to the analysis of scale-up in situations where shear or mass transfer may be limiting factors, situations which are particularly likely to arise in animal cell culture.     

Physical variation and history in Melanesia and Australia

Local biological variation is marked in Melanesia. Some of it may result from gene flow from Micronesia, but the essential variation appears to result from isolation due to social fragmentation, and to genetic drift in place. In different regions, the variation may correspond well with language relationships, and probably constitutes differentiation which has been preserved over a considerable period, especially since the arrival of horticulture and development of village farming. However, none of this patterning suggests distinct waves of migration into Melanesia. Variation among Australian aboriginal groups is smaller, though far from absent. It may reflect a hunting culture together with social customs allowing more intertribal marriage than is typical of Melanesia. While phenotypically Australians and Melanesians differ, cranially they are closely allied, as against other major human groups. It is suggested that the genetic and phenotypic variety is old, that it existed in the previous home of the Australo-Melanesians (Old Melanesia, comprising present Indonesia and the Phillipines) at least back to 40,000 years ago, and that much of the variation in Melanesia and Australia, including their differences, results from the sampling process involved when different groups out of the original populations made early crossings of the water barriers from Old Melanesia.     

Presumed Behavior: Modification of the Ideal-Real Dichotomy

Anthropologists have long been aware of the difference between the ideal pattern in society (what people think should or should not be done) and real behavior (what actually is done). This article calls attention to the importance of a third element, presumed behavior, or what people think is being done in the society. Since people tend to act on the basis of what they think others are doing (which may not coincide at all with what people are actually doing, or with the ideal pattern) knowledge of the presumed behavior is highly significant in understanding and predicting social behavior.     

The Production of Urban Space by Violence and its Aftermath in Jakarta and Kota Ambon,Indonesia

Violence has an enormous potential impact on the production of urban space. This article presents an analysis of how violence has made an impact on Indonesian cities since 1998. Using case material from communal violence in Kota Ambon, and lynching and vigilantism in Jakarta, the article addresses the question what impact did violence have on the spatial restructuring of some Indonesian cities and, conversely, – assuming that the people who used violence are slowly relinquishing its use – what impact does the restoration of law and order have on urban space? How enduring are some of the underlying, historical patterns of violence and do many of them still exist, hidden under the surface, today?     

Affinities among Melanesians,Micronesians, and Polynesians: a neutral biparental genetic perspective

The human colonization of Remote Oceania, the vast Pacific region including Micronesia, Polynesia, and Melanesia beyond the northern Solomon Islands, ranks as one of the greatest achievements of prehistory. Many aspects of human diversity have been examined in an effort to reconstruct this late Holocene expansion. Archaeolinguistic analyses describe a rapid expansion of Austronesian-speaking "Lapita people" from Taiwan out into the Pacific. Analyses of biological markers, however, indicate genetic contributions from Pleistocene-settled Near Oceania into Micronesia and Polynesia, and genetic continuity across Melanesia. Thus, conflicts between archaeolinguistic and biological patterns suggest either linguistic diffusion or gene flow across linguistic barriers throughout Melanesia. To evaluate these hypotheses and the general utility of linguistic patterns for conceptualizing Pacific prehistory, we analyzed 14 neutral, biparental genetic (short tandem repeat) loci from 965 individuals representing 27 island Southeast Asian, Melanesian, Micronesian, and Polynesian populations. Population bottlenecks during the colonization of Remote Oceania are indicated by a statistically significant regression of loss of heterozygosity on migration distance from island Southeast Asia (r = 0.78, p < 0.001). Genetic and geographic distances were consistently correlated (r > 0.35, p < 0.006), indicating extensive gene flow primarily focused among neighboring populations. Significant correlations between linguistic and geographic patterns and between genetic and linguistic patterns depended upon the inclusion of Papuan speakers in the analyses. These results are consistent with an expansion of Austronesian-speaking populations out of island Southeast Asia and into Remote Oceania, followed by substantial gene flow from Near Oceanic populations. Although linguistic and genetic distinctions correspond at times, particularly between Western and Central-Eastern Micronesia, gene flow has reduced the utility of linguistic data within Melanesia. Overall, geographic proximity is a better predictor of biparental genetic relationships than linguistic affinities.     

Evolutionary history of a widespread Indo-Pacific goby: the role of Pleistocene sea-level changes on demographic contraction/expansion dynamics

Compared to endemics, widespread species are of particular interest to retrace recent evolutionary history. These species have a large population size which provides a clearer genetic signature of past events. Moreover, their wide geographic range increases the potential occurrence of evolutionary events (expansion, divergence, etc.). Here, we used several coalescent-based methods to disentangle the evolutionary history of a widespread amphidromous goby (Sicyopterus lagocephalus), in the light of sea-level variations during the Pleistocene. Using 75 samples recovered from three biogeographic regions (Western Indian Ocean, Melanesia and Polynesia), we analysed a portion of the cytochromeb gene and confirmed three major haplogroups, each specific to a region. Furthermore, we found that: (1) the Melanesian haplogroup was the oldest while the two peripheral regions hosted daughter haplogroups; (2) two centrifugal colonisation events occurred from Melanesia to the periphery, each synchronised with periods of strong paleo-ENSO episodes; (3) the demographic contraction-expansion events were linked to Pleistocene sea-level changes; (4) Melanesia and Polynesia acted as efficient refuges during the Last Glacial Maximum. These results highlight the importance of studying widespread species to better understand the role of climate changes and paleo-oceanography on the evolution of biodiversity.
