New visions, old practices: policy and regulation in the internet era

Raymond Williams’ comment applies as much to the media and communication systems of his time as it does to today’s Internet era. As Silverstone (2007: 26) wrote, “mediated connection and interconnection define the dominant infrastructure for the conduct of social, political and economic life across the globe”. The Internet is no more a neutral configuration of technologies than was the earlier media and communication system. If there are forces that are shaping the Internet’s development in ways that are not equitable then there is a case for countering them. This paper offers an assessment of current trends in policy and regulation that bear on the Internet. The aim is to discern whether visions of a post-neoliberal period are visible in policy and regulatory practice in this area. Though some argue that developments in Internet governance are beginning to wrest control of the Internet away from state or private sector influence, I suggest that this is a very one-sided view. In this paper, I argue that the forces influencing Internet developments are not benign because an unregulated Internet is unlikely to maximise the benefits of the Internet for all. This paper focuses on corporate interests in the Internet’s evolution and on the state’s role in regulating various components of the infrastructure and services that employ the Internet. The following section considers the paradoxical alliance between the neoliberal agenda and the advocates of the open unregulated Internet. The impact of the neoliberal agenda on the telecommunication, broadcast and Internet segments of the media and communication industry is then considered briefly, providing a basis for a more in-depth consideration of the incentives encouraging corporate actors to engage in monopolisation strategies as a means of maximising their profits. In the penultimate section, the likelihood of a shift to policy based on a post-neoliberal paradigm is explored through an examination of some recent developments in network infrastructure, broadcast content and radio frequency spectrum policy

A genome scan reveals QTL for growth, fatness, leanness and meat quality in a Duroc-Pietrain resource population

We performed a genome-wide QTL scan for production traits in a line cross between Duroc and Pietrain breeds of pigs, which included 585 F(2) progeny produced from 31 full-sib families genotyped with 106 informative microsatellites. A linkage map covering all 18 autosomes and spanning 1987 Kosambi cM was constructed. Thirty-five phenotypic traits including body weight, growth, carcass composition and meat quality traits were analysed using least square regression interval mapping. Twenty-four QTL exceeded the genome-wide significance threshold, while 47 QTL reached the suggestive threshold. These QTL were located at 28 genomic regions on 16 autosomal chromosomes and QTL in 11 regions were significant at the genome-wide level. A QTL affecting pH value in loin was detected on SSC1 between marker-interval S0312-S0113 with strong statistical support (P < 3.0 x 10(-14)); this QTL was also associated with meat colour and conductivity. QTL for carcass composition and average daily gain was also found on SSC1, suggesting multiple QTL. Seventeen genomic segments had only a single QTL that reached at least suggestive significance. Forty QTL exhibited additive inheritance whereas 31 QTL showed (over-) dominance effects. Two QTL for trait backfat thickness were detected on SSC2; a significant paternal effect was found for a QTL in the IGF2 region while another QTL in the middle of SSC2 showed Mendelian expression
