Induced ovulation, spawning, egg incubation, and hatching of the cyprinid fish Labeo victorianus in captivity

Ningu Lubeo victorianus is the only labeine fish within Lake Victoria and its catchment (Greenwood 1966; Reid 1985). This species, once widely distributed in the Lake Victoria basin and supporting a commercial fishery until the late 195Os, has declined due to overfishing (Cadwalladr 1965; Ogutu-Ohwayo 1990; Seehausen 1996). The L. victorianus fishery has not only collapsed but the species has also disappeared from some of its former habitats. Recent surveys in Uganda have only found two distant populations-one in the Sio River on the Uganda-Kenya border (0” I3’53”N, 34”00’30’E), and the second in the Kagera River on the Uganda-Tanzania border (0°56’28.1”S, 3 1’46’ 18”E) (Rutaisire 2003) (Fig. 1). Currently, there is growing interest to breed the fish for wild stock enhancement and culture as a food fish

Put to the Test: For a New Sociology of Testing

In an age defined by computational innovation, testing seems to have become ubiquitous, and tests are routinely deployed as a form of governance, a marketing device, an instrument for political intervention, and an everyday practice to evaluate the self. This essay argues that something more radical is happening here than simply attempts to move tests from the laboratory into social settings. The challenge that a new sociology of testing must address is that ubiquitous testing changes the relations between science, engineering and sociology: Engineering is today in the very stuff of where society happens. It is not that the tests of 21st Century engineering occur within a social context but that it is the very fabric of the social that is being put to the test. To understand how testing and the social relate today, we must investigate how testing operates on social life, through the modification of its settings. One way to clarify the difference is to say that the new forms of testing can be captured neither within the logic of the field test nor of the controlled experiment. Whereas tests once happened inside social environments, today’s tests directly and deliberately modify the social environment

Self-Sovereign Identity Systems Evaluation framework

Digital identity systems have been around for almost as long as computers and have evolved with the increased usage of online services. Digital identities have traditionally been used as a way of authenticating to the computer systems at work, or a personal online service, such as an email. Today, our physical existence has a digital counterpart that became an integral part of everyday life. Self-Sovereign Identity (SSI) is the next step in the evolution of the digital identity management systems. The blockchain technology and distributed ledgers have provided necessary building blocks and facilities, that bring us closer to the realisation of an ideal Self-Sovereign Identity. But what exactly is an ideal Self-Sovereign Identity? What are the characteristics? Trade-offs? Here, we propose the framework and methodology that can be used to evaluate, describe, and compare SSI systems. Based on our comparison criteria and the evaluation framework, we present a systematic analytical study of existing SSI systems: uPort, Sovrin, ShoCard, Civic, and Blockstack

Pornostyle: Sexualised Dress and the Fracturing of Feminism

This article is premised on the suggestion that there are now two separate Western systems of fashion; here the word “system” is not intended to evoke the model suggested by Roland Barthes, but rather to refer, quite simply, to a pragmatic “system” of design, manufacture, distribution, and dissemination, similar to the cultural studies’ “circuit of culture” model of analysis. A new, unacknowledged “system” of design and promotion has emerged in the last decade, which has its own fashion leaders in young female celebrities, its own magazines to chronicle their activities and showcase their style, its own Internet presence, and its own retailing patterns. These young women often resemble in their self-presentation the “glamour models” or pin-up girls of popular men’s magazines, whose “look” is a muted version of the styling associated by many with that of hard-core pornography. The “body ideal” of this alternative system is very different to that of high-fashion; once again, it resembles the look of the women pictured in magazines for men. Although one or two writers on fashion have noted this new trend, it is feminist scholars who have shown most interest; they see the new system as part of the “pornification” of contemporary visual culture. A number of these same scholars are avowed anti-pornography campaigners and I argue that this could further damage the fragile feminist project, already riven by differences

Media coverage of cloning: A study of media content, production and reception

This paper presents the results of empirical research that analyzed UK news media coverage of cloning. More specifically, it describes how quantitative and qualitative methods were used to examine the production, content and reception of newspaper and television news coverage of cloning. The paper documents the results of a systematic analysis of two years of media content (1996 and 1997), a period that includes the announcement that a Finn Dorset sheep (Dolly) had been cloned from a somatic cell. Interviews with media professionals and the Roslin Institute examined the processes of mediation involved in producing this coverage. A reception analysis, which investigated the significance of this coverage in informing respondents’ views about cloning, showed that these respondents were particularly influenced by coverage of Dolly the sheep. In conclusion, the paper considers how media coverage of cloning might influence the construction of scientific citizenship
