The turbulence of images: On imagery,media and ethnographic discourse

As the anthropological theory of politeness has put it, people have universally two kinds of social want. They wish to be close to others, liked and accepted, but they also want some distance, freedom from imposition and respect of mutual difference. These wants, which one may also call basic human rights, are however often violated, and images play an important role in this.

Images are ultimately generated in the human mind and may find verbal as well as written and pictorial representation. Tyler [1978] has proposed a typology of mental images based on criteria of conscious control, completeness, abstraction, media and autonomy. These criteria also prove useful when probing into prototypical usages of intrusive imagery such as cursing, blessing, magic, witchcraft and the evil eye. Also the criteria help one understand the subtle process by which imagery can lead to the articulation and even discovery of peoples’ selves.

Ethnographic discourse has always been to a large extent about images, but until recently the ethnographer stood between his or her audience and the people of whom he or she was speaking or writing. Now, as sound recordings, film and video have arrived, this allows for richer varieties of cooperation where the non‐literate counterparts of the ethnographer can make more expressive and coherent contributions than before.

Also it seems that in the face of suppression people welcome the new media as a support in their ongoing battle for a recognition of their cultural and social worthiness.     

Pikisi kwaiyai! (pictures tonight!): The screening and reception of ethnographic film in the Trobriand Islands,Papua New Guinea

Ethnographic films hold great historical value for the communities in which they were filmed, yet people in source communities often lack access to them. Visitors engaging in ‘visual repatriation’ of ethnographic film can enrich both sides of the ethnographic exchange. I review my experiences screening ethnographic films with Trobriand Islanders, their reactions, and the various ways in which local communities regain ownership of these films, including re‐narration and renaming. My findings reiterate how source communities' reception of, and uses for, ethnographic film can sharply differ from the filmmakers' original agenda.     

The anthropologist as photographer: The visual construction of ethnographic authority

“The Anthropologist as Author"—Clifford Geertz's formulation is emblematic of a theme of anthropology in the 1980s, ethnographic writing. Ethnographic photography, however, was barely a subject of consideration. Reviewing Evans‐Pritchard's The Nuer, a book widely re‐read in the writing culture debate, this article investigates not only the author's visual construction of ethnographic authority. It also reveals ethnographic photography as a medium, which can undermine this authority in a subtle yet compelling manner. Thus concentrating on the medium itself this paper investigates the uneasy relationship between photography and anthropology, and proposes an approach to ethnographic photography that goes beyond the questions of representation.¹     

Living krill, zooplankton and experimental investigations: a discourse on the role of krill and their experimental study in marine ecology

Krill occupy critical positions in a many marine ecosystems and have been the subject of a number of concerted studies yet there are large areas of their biology that still remain a mystery. Most species of krill are open ocean animals, which makes direct observation and sampling difficult. Krill also exhibit a number of physiological and behavioural attributes which frustrate attempts to understand their life history. Krill are conceptually difficult to come to terms with; they are obviously different from larger marine organisms such as squid, fish, whales and fish yet they are also quite distinct from those animals classed as zooplankton such as copepods. Despite these differences they have most often been grouped with zooplankton and have been studied using techniques developed for animals which are orders of magnitude smaller than they. This mismatch has affected our view of their interactions with the physical world and also affects their perceived trophic interactions. Their size and mobility also interferes with our ability to sample them effectively and thus to develop our appreciation of their true role in the marine ecosystem. Understanding how intermediate-sized animals, such as krill, function in aquatic ecosystem is critical to better management of the marine environment.

The Neandertal genome and ancient DNA authenticity

Recent advances in high‐thoughput DNA sequencing have made genome‐scale analyses of genomes of extinct organisms possible. With these new opportunities come new difficulties in assessing the authenticity of the DNA sequences retrieved. We discuss how these difficulties can be addressed, particularly with regard to analyses of the Neandertal genome. We argue that only direct assays of DNA sequence positions in which Neandertals differ from all contemporary humans can serve as a reliable means to estimate human contamination. Indirect measures, such as the extent of DNA fragmentation, nucleotide misincorporations, or comparison of derived allele frequencies in different fragment size classes, are unreliable. Fortunately, interim approaches based on mtDNA differences between Neandertals and current humans, detection of male contamination through Y chromosomal sequences, and repeated sequencing from the same fossil to detect autosomal contamination allow initial large‐scale sequencing of Neandertal genomes. This will result in the discovery of fixed differences in the nuclear genome between Neandertals and current humans that can serve as future direct assays for contamination. For analyses of other fossil hominins, which may become possible in the future, we suggest a similar ‘boot‐strap’ approach in which interim approaches are applied until sufficient data for more definitive direct assays are acquired.     

The application of biotechnological methods in authenticity testing

By counterfeiting brand names in the food and drink industry as well as fraudulently labelling and selling low quality products as premium products, this sector of the industry has lost significant amounts of money and the consumer has been deceived. While it was difficult to establish certain types of fraud before the advent of modern biotechnology, DNA-based methods make an important contribution to protect high-quality brand names and protect the consumer. Several years ago, DNA technologies were considered as methods used in universities, primarily for research purpose, not so much for 'real-life' applications. However, this has changed and a number of laboratories have specialised in offering such services to the industry. This article will review DNA-based techniques commonly used for authenticity testing.     

Beyond proteinuria: VDR activation reduces renal inflammation in experimental diabetic nephropathy

Local inflammation is thought to contribute to the progression of diabetic nephropathy. The vitamin D receptor (VDR) activator paricalcitol has an antiproteinuric effect in human diabetic nephropathy at high doses. We have explored potential anti-inflammatory effects of VDR activator doses that do not modulate proteinuria in an experimental model of diabetic nephropathy to gain insights into potential benefits of VDR activators in those patients whose proteinuria is not decreased by this therapy. The effect of calcitriol and paricalcitol on renal function, albuminuria, and renal inflammation was explored in a rat experimental model of diabetes induced by streptozotocin. Modulation of the expression of mediators of inflammation by these drugs was explored in cultured podocytes. At the doses used, neither calcitriol nor paricalcitol significantly modified renal function or reduced albuminuria in experimental diabetes. However, both drugs reduced the total kidney mRNA expression of IL-6, monocyte chemoattractant protein (MCP)-1, and IL-18. Immunohistochemistry showed that calcitriol and paricalcitol reduced MCP-1 and IL-6 in podocytes and tubular cells as well as glomerular infiltration by macrophages, glomerular cell NF-κB activation, apoptosis, and extracellular matrix deposition. In cultured podocytes, paricalcitol and calcitriol at concentrations in the physiological and clinically significant range prevented the increase in MCP-1, IL-6, renin, and fibronectin mRNA expression and the secretion of MCP-1 to the culture media induced by high glucose. In conclusion, in experimental diabetic nephropathy VDR activation has local renal anti-inflammatory effects that can be observed even when proteinuria is not decreased. This may be ascribed to decreased inflammatory responses of intrinsic renal cells, including podocytes, to high glucose.     

The use of flexible film isolators for housing experimental animals

The change-over from conventional husbandry to the housing of minimal-disease experimental animals kept in flexible-film isolators resulted in improved survival and thus more definitive experimental results. The disadvantages and advantages of the change are discussed.     

An investigation of processing and consumption of pulses among prehistoric societies: archaeobotanical, experimental and ethnographic evidence from Greece

Pulses have constituted an important food source for prehistoric communities in the Old World, yet little is known as regards their processing for consumption through the archaeobotanical record. This paper provides an overview of archaeobotanical evidence for the use of pulses in prehistoric Greece based on two case studies from the north, and explores (a) their preparation for consumption, in particular their detoxification and (b) the consumption of pulses as a component of ordinary daily meals in prehistoric times, as well as those for special occasions, within a context of feasting and ritual. The paper examines charred remains of Vicia ervilia (bitter vetch) and Lathyrus sativus (grass pea) from early Bronze Age Agios Athanasios and late Neolithic Kremasti Koiladas, respectively, as the former provides a basis for a pilot exploration of pulse detoxification and the latter, due to its origin, offers a rare opportunity to discuss the context of consumption. In the pilot exploration of pulse seed preparation for consumption, the inner cotyledon morphology of modern V. ervilia seeds which were experimentally processed with water and pounding was examined macroscopically and through SEM micrographs. Preliminary observations suggest that intentional splitting of pulse seeds as part of processing for consumption as food may be recognisable in the archaeobotanical record. Processing with water may also be detected. The particular context of the Kremasti finds suggests that pulses, in this particular case L. sativus, may have constituted special foods for particular occasions, loaded with symbolic meaning.     

National ceremonies: the pursuit of authenticity

Abstract

This article asks what, if any, impact national ceremonies have on the formation of national identities. Why are some ceremonies perceived as national and persistent through time, while others fail to achieve that status? It argues that national ceremonies can only be examined as specific types of situations – performances, rather than rituals – characterized by the relationship between performers and their audiences. Following Jeffery Alexander's cultural pragmatics theory, national ceremonies are seen as successful only when a performance is perceived as authentic. A ceremony's authenticity is, at best, a quality of experience among its audience. Only when the audience is transformed into willing participants through a performance's mise-en-scène can a national ceremony be seen as a ritual-like performance. The paper will conclude that the efficacy of these performances is temporary, and that even when a performance succeeds in creating a community of shared experience, that community dissolves with the end of the performance.
