Effects of various medical and social pracitices on the frequency of genetic disorders.

The effects of a number of new medical and social practices on the incidence of genetic diseases and gene frequency have been studied. The results deal with short-term effects, since these are of most practical importance, and with the combined effects of several factors acting together. The size of any effects depends on the feasibility of the different practices and on the extent to which they are adopted by the population. Most of the practices reduce the incidence of the diseases in the next generation, but some may be dysgenic. For example, improved treatment of affected individuals in dominant and X-linked diseases could lead to improved reproductive fitness, higher gene frequencies, and to an increased incidence in future generations. However, such deleterious effects may be avoided by genetic counseling or offset by other preventive practices. In recessive disorders, a small reduction in the average fitness of carfiers detected by population screening would outweigh any deleterious effects of other practices. In general there seems to be little cause for alarm about the deleteious effects of the new medical and social practices being adopted.     

Afterword to "Anthropology and Human Rights in a New Key": The Social Life of Human Rights

In this article, I argue for an ethnographic approach to human rights that recognizes the plural and fragmentary nature of the international rights regime and the ideological promiscuity of rights talk. Instead of determining in advance the social or political character of rights, anthropologists could profitably draw from the insights of early-20th-century "legal realists" and look closely at the underlying assumptions and hidden practices of political and legal processes. Studying the "social life of human rights" would involve focusing on, inter alia, the performative dimensions of human rights, the dynamics of social mobilization, and the attitudinal changes of elite and nonelite social actors towards formulations of "rights" and "justice," both inside and outside the legal process. I conclude with a review of recent anthropological research on human rights epistemology and evaluate its implications for human rights policy.

The Politics of Tradition: Toward a Generic Culture in Vanuatu

The paper examines the role of the elite in generating constructions of tradition in present-day Vanuatu. While stopping short of postulating a ‘conspiracy theory’ interpretation, the paper does argue that the proto-bureaucratic 'class' is attempting to gain control over a symbolic code derived from traditional practices (kastom) so as to promote social cohesion and establish a civil polity. The negative case of kava, a symbol of traditional culture which was significantly not included in this corpus is discussed at length.     

Dead Media Objects and the Experience of the (Once) Modern. Ethnographic Perspectives from the Living Rooms of Kinshasa’s Old Aged

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.     

Sexual mores,promiscuity and ‘prostitution’ in Botswana

In Botswana there is a large, and increasing, number of women who do not marry but have one or several lovers simultaneously and have gifts from these menas an importantpart of their income. It is argued that the processual and practical character of traditional marriages, combined with weak social institutions, provides those who wish the basis on which to legitimise such informal sexual relationships. Such practices represent a new sexual morality, whose conditions are further explained by treating the term ‘prostitution’ in a comparative perspective. Tensions arise from the new constellation of sexual mores, generating fundamental social changes — most notably substantial economic transfers from men to women, loss of male power, and changing gendered identities. Lastly, the practices described are discussed in relation to the AIDS epidemic.     

Money,morality and new forms of exchange in postsocialist Ukraine

One of the legacies of Soviet socialism is a moralizing lens through which to evaluate wealth and consumption practices. A contrast between the moral underpinnings of generating and consuming wealth under capitalism and those emerging in postsocialist Ukraine shows that socioeconomic differences are emerging as proxies for moral indictments that strain the social fabric. Soviet-era economic practices and exchange networks of favors are giving way to cash-based forms of exchange that are redefining moral commitments to social obligations. When legal codes are mobilized in diverse ways in response to divergent moralities the forging of moral consensus to shape emerging economic practices is rendered elusive.     

Perspectives and hopes in infectious pathology]

Over the last few decades, changes in socio-economic conditions and social practices as well as aggressive therapy of many diseases have led to the emergence of new infectious pathologies. These new pathologies are either associated with newly identified microbial species or the emergence of known microbes which have encountered new environments in which they are able to cause disease. Recent progress has allowed us to understand the mechanisms by which these pathogens express their virulence and will certainly allow us to diagnose and treat these infections more efficiently in the future.     

Microsatellite Variations of Elite Setaria Varieties Released during Last Six Decades in China

Crop improvement is a multifaceted micro-evolutionary process, involving changes in breeding approaches, planting configurations and consumption preferences of human beings. Recent research has started to identify the specific genes or genomic regions correlate to improved agronomic traits, however, an apparent blank between the genetic structure of crop elite varieties and their improving histories in diverse modern breeding programs is still in existence. Foxtail millet (Setaria italica) was one of the earliest cereal crops to be domesticated and served as a staple crop for early civilizations in China, where it is still widely grown today. In the present trial, a panel of foxtail millet elite varieties, which were released in the last sixty years in different geographical regions of China, was characterized using microsatellite markers (SSRs). A clear separation of two subpopulations corresponding to the two eco-geographical regions of foxtail millet production in China was identified by the dataset, which also indicated that in more recently released elite varieties, large quantities of accessions have been transferred from spring-sowing to summer-sowing ecotypes, likely as a result of breeding response to planting configurations. An association mapping study was conducted to identify loci controlling traits of major agronomic interest. Furthermore, selective sweeps involved in improvement of foxtail millet were identified as multi-diverse minor effect loci controlling different agronomic traits during the long-term improvement of elite varieties. Our results highlight the effect of transition of planting configuration and breeding preference on genetic evolvement of crop species.     

Poetry and Precision: Johannes Thienemann,the Bird Observatory in Rossitten and Civic Ornithology, 1900–1930

In the early twentieth century, ornithology underwent significant changes. So far, these changes, basically, have been studied by focussing on the elite of professional biologists working at universities or state museums. However, important developments also occurred in what Lynn Nyhart has called “the civic realm” of science – the sphere given form by private naturalist associations, nature writers, taxidermists and school teachers. This article studies the changing dynamics of civic ornithology, by looking at one particular case: the influential orinthological observatory in Rossitten, East-Prussia. This observatory, the first of its kind, was founded in 1901 and led, for the first three decades of its existence, by the minister Johannes Thienemann. This article analyses the ornithological practices Thienemann developed in Rossitten and the rhetoric he used to defend these practices. In both, so it is argued, one finds a mixture of the traditional, locally anchored naturalist approach with the new ideals of the “modern” and “experimental” university laboratories. The innovations which Thienemann introduced in this hybrid form of ornithology called for specific spatial strategies which made optimal use of the natural chatacteristics of his workplace and which mobilized a large civic network of geograhically scattered amateurs. At the same time, his work also altered the space he shared with the birds – materially, conceptually and culturally. Thus, this article maintains Thienemann's ornithology can only be understood by acknowledging its continuous interaction with the geographical and civic context in which it arose.     

Racehorses are getting faster

Previous studies have concluded that thoroughbred racehorse speed is improving very slowly, if at all, despite heritable variation for performance and putatively intensive selective breeding. This has led to the suggestion that racehorses have reached a selection limit. However, previous studies have been limited, focusing only on the winning times of a few elite races run over middle and long distances, and failing to account for potentially confounding factors. Using a much larger dataset covering the full range of race distances and accounting for variation in factors such as ground softness, we show that improvement is, in fact, ongoing for the population as a whole, but driven largely by increasing speed in sprint races. In contrast, speed over middle and long distances, at least at the elite level, appears to be reaching an asymptote. Whether this reflects a selection limit to speed over middle and long distances or a shift in breeding practices to target sprint performances remains to be determined.     

Adolescent Movements: Dating,Elopements, and Youth Policing in Ladakh,India

ABSTRACT

In India's northwest border region of Ladakh, norms of sexuality are changing, which is resulting in the emergence of new sexual practices, such as dating, ‘roaming’, and the dramatic elopements of Buddhist and Muslim youth. This has caused the emergence of youth policing the perceived sexual infractions of others, through targeting particular zones of intimacy – marriage, religious identity, and mobility. Yet, youth policing is uneven, targeting those considered to be the most ‘at risk’ for moral transgressions, including Buddhists, the elite, and those pursuing education. Ladakhi youth are in a tenuous position, where they negotiate their desires to be ‘modern’ with the community pressure to maintain a strong sense of cultural identity. This paper examines how youth navigate between tensions of modernity and culture, showing that they employ a range of strategic practices and tactics that provide space for expressing desires for modernity, while simultaneously securing cultural loyalty.     

‘Do you have a mobile?’ Mobile phone practices and the refashioning of social relationships in Port Vila Town

Mobile phones have quickly become an important part of young people's social relationships in Port Vila Vanuatu. In particular, young people embrace the new technology's capacity to broaden the breadth of their sociality. They use the mobile phone to facilitate private and secretive communication, engage in unsanctioned relationships, pre‐marital sexual relationships, and also multiple concurrent intimate relationships. Literature on mobile phone use often either takes the approach that mobile phone technology becomes purely incorporated into pre‐existing social practices, or that it dramatically reshapes social ontologies. The present article argues for an alternative view, one that takes into account the nuances between these two analytical poles. This article suggests that young people use the mobile phone in practices informed by previous models of social relationships, yet the specific materiality of the mobile phone technology is influencing the direction in which models of social relationships are changing. In demonstrating this point, I pay particular attention to two material aspects of the mobile phone technology ‐ the mobile phone as a repository of a particular kind of information ‐ ‘evidence’, and the capacity of the mobile phone to ‘disconnect’ people from their relationships by switching off the mobile. This article argues that these practices are influencing the emergence of a radically altered kinship and gender landscape in the urban context.     

Generating and maintaining diversity at the elite level in crop breeding

Most breeding programs develop elite genotypes that are well adapted to the normal range of environmental conditions in the target production region. These elite lines have similar essential alleles for desirable end use characteristics, agronomics, disease resistance, and adaptation in the target region. The genetic makeup of these elite lines is complex. Intermating among the elite lines will often produce new variability through recombination with minimal risk of introducing new undesirable features, and is the source of most new cultivars. Eventually, this variation will be exhausted and new alleles must be introduced into the elite breeding population. Introducing desirable alleles from exotic germplasm may "pollute" the elite gene pool with undesirable alleles. Exotic germplasm may also disrupt essential allele combinations for adaptation, quality, and agronomic performance. New desirable alleles from exotic germplasm can be introgressed into an elite population in a systematic way through limited backcrossing with a minimal disturbance to the finely tuned elite background. Combining recurrent selection within elite germplasm with a systematic introgression from exotic germplasm in the recurrent introgressive population enrichment (RIPE) system has created an open-ended, continually improving, and sustainable elite population breeding system, which is simple, effective, and a regular source of new cultivars.     

OPTIMAL INVESTMENT IN SOCIAL SIGNALS

This study is an attempt to determine how much individuals should invest in social communication, depending on the type of relationships they may form. Two simple models of social relationships are considered. In both models, individuals emit costly signals to advertise their “quality” as potential friends. Relationships are asymmetrical or symmetrical. In the asymmetrical condition (first model), we observe that low‐quality individuals are discouraged from signaling. In the symmetrical condition (second model), all individuals invest in communication. In both models, high‐quality individuals (elite) do not compete and signal uniformly. The level of this uniform signal and the size of the “elite” turn out to be controlled by the accuracy of signals. The two models may be relevant to several aspects of animal and human social communication.     

Age-dependent transformation frequency in elite wheat varieties.

Wheat is a major world crop and as such is a primary target for improvement of agronomic characteristics via genetic engineering. Optimization of transformation is essential in order to overcome the relatively low transformation frequencies encountered with wheat. Transformation of elite wheat varieties is not always successful due to variability in regeneration and transformation frequencies between varieties. In this work, two elite wheat varieties with a relatively high embryogenic capacity were transformed by particle bombardment. A strong correlation between transformation frequency and the age of wheat donor plants was observed in both varieties. The mean transformation frequency rose from 0.7% to 5% when using immature embryos from old and young donor plants, respectively. This was observed in both varieties, the best bombardments achieving up to 7.3% frequency. Using explants at an optimal developmental stage from donor plants grown under environmentally-controlled conditions has improved the reproducibility of transformation efficiency of elite wheat varieties and leads to the production of apparently phenotypically normal, fertile, transgenic plants.     

The Invention of Fine Art: Creating a Cultural Elite in a Marginal Community

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.
