Across the great divide

Chapman & Huffman’s target article calls for a reevaluation of claims of human uniqueness and superiority. It also adds to the literature on how species differences, as Darwin noted, are more of degree than kind. The threats to environmental health and species survival are a consequence of excluding nonhuman animals from moral concern and consideration. The theory of intersectionality should include speciesism in the array of discriminatory practices

Across the great divide : chimeras and species boundaries

Thesis (S.M. in Science Writing)--Massachusetts Institute of Technology, Dept. of Humanities, Program in Writing and Humanistic Studies, 2004.Vita.Includes bibliographical references (leaves 40-43).We have always been fascinated by borderline creatures. Chimeras, hybrids of multiple animals-and sometimes humans-appear repeatedly in mythology across cultures from ancient times to the present. Since the early 1980s, scientists have been creating cross-species chimeras, first combining mouse species that could not interbreed naturally, then moving on to create chimeras from even more distantly related animals such as sheep and goats. Scientists use chimeras to study fundamental processes of life such as pregnancy, fetal development, and the progress of disease. Chimeras allow scientists to perform experiments that would otherwise be impossible. Ancient chimera myths played on our anxieties about the boundary between man and animal. Interspecies chimeras strike the same chords of disgust and fear in some people as these ancient mythical chimeras did. This paper examines the science of chimeras and biological borderlines and the social implications of creatures that challenge accepted and comfortable ideas about the divisibility of the animal and human worlds. Can human-animal chimeras be made? Activists Stuart Newman and Jeremy Rifkin have filed a patent application for human-animal chimeras, such as the humanzee, to protest patents on all life forms. Newman and Rifkin believe chimeras are emblematic of abuses of biotechnology and are on a slippery slope to human cloning and elimination of the distinction between natural and manufactured things. They are not alone in believing scientists should be more concerned about the ethical implications of their work. However, a majority of scientists, bioethicists, and scholars find Newman and Rifkin's viewpoint extreme. The creation of chimeras between species-groups of animals that(cont.) definition cannot interbreed-may seem to challenge the historically-shaky biological species concept. Goat and sheep cells can work together in a single healthy organism. Does this undermine the taxonomical boundaries between them? While existing in a confusing zone between species, chimeras do not challenge the biological species concept as directly as may seem. When these chimeras are viable, they demonstrate shared common ancestry through evolution. Because chimeras cannot breed and generate more chimeras, they do not challenge the species concept.by Katherine Anne Bourzac.S.M.in Science Writin

Social dynamics in conferences: analyses of data from the Live Social Semantics application

Popularity and spread of online social networking in recent years has given a great momentum to the study of dynamics and patterns of social interactions. However, these studies have often been confined to the online world, neglecting its interdependencies with the offline world. This is mainly due to the lack of real data that spans across this divide. The Live Social Semantics application is a novel platform that dissolves this divide, by collecting and integrating data about people from (a) their online social networks and tagging activities from popular social networking sites, (b) their publications and co-authorship networks from semantic repositories, and (c) their real-world face-to-face contacts with other attendees collected via a network of wearable active sensors. This paper investigates the data collected by this application during its deployment at three major conferences, where it was used by more than 400 people. Our analyses show the robustness of the patterns of contacts at various conferences, and the influence of various personal properties (e.g. seniority, conference attendance) on social networking patterns

Across the great divide: the economy of the inland corridor

In current debates about regional Australia, many observers point to a gap in incomes and access to services between Australia’s capital cities and the rest of the nation. Supporters of this view tend to see government intervention as necessary to reverse the declining fortunes of regions and encourage industries to relocate away from congested capital cities. An alternative view is that regional Australia has become differentiated, which suggests that more flexible government intervention, targeting regions that are capable of driving growth in local economies, is warranted. This paper considers the ways in which a historical perspective might shed light on this debate. An overview of the economic history of the Inland Corridor in the 19th and 20th centuries reveals complex patterns of conditions that varied across space and over time. A dense network of small towns, established when transport and manufacturing technologies were simple, provided a connection between primary producers and external markets. After World War I, technological and global forces weakened the traditional link between farm output and economic activity and left country towns vulnerable to decline. None of these trends is explained adequately by the ‘divide’ that contemporary observers perceived between politically powerful, parasitic capital cities and their resource-starved hinterlands. This suggests that it is more appropriate to see the regional Australia of today as an evolving system of conditions, with some regions diversifying and responding to new economic opportunities more effectively than others, rather than a sector that is in general decline
