    'Red Storm Ahead': Securitisation of Energy in US-China Relations

    Get PDF
    Energy is becoming more and more important to state survival and economic development, and is increasingly considered an issue of ‘national security’. In 2005, the bid by China National Offshore Oil Corporation (CNOOC) for US energy company Unocal was securitised by US elite actors, who called for presidential action on the grounds of ‘national security’. This article argues that securitisation of energy is problematic, as it impedes cooperation and encourages strategic and/or economic competition between states over energy supplies by tying energy to a national security ‘us vs. them’ scenario. Moreover, it limits the energy security debate. The article will use a securitisation approach to analyse the discourse of the Unocal affair, together with a smaller complementary case study of US–China cooperation on shale gas to show the possibility of dealing with energy in desecuritised terms. It argues that the current literature on energy ‘security’ analyses policy in overly simplistic competition/cooperation terms and fails to recognise the policy implications of securitising energy. In contrast, a securitisation approach to energy can explain the (re)presentation of energy as a policy issue and allows an analysis of how using particular discourse makes particular policy possible, while silencing alternative policy options. This has implications for policy-making in this area as energy policy/practice should be desecuritised

    The Off-Shell Nucleon-Nucleon Amplitude: Why it is Unmeasurable in Nucleon-Nucleon Bremsstrahlung

    Full text link
    Nucleon-nucleon bremsstrahlung has long been considered a way of getting information about the off-shell nucleon-nucleon amplitude which would allow one to distinguish among nucleon-nucleon potentials based on their off-shell properties. There have been many calculations and many experiments devoted to this aim. We show here, in contrast to this standard view, that such off-shell amplitudes are not measurable as a matter of principle. This follows formally from the invariance of the S-matrix under transformations of the fields. This result is discussed here and illustrated via two simple models, one applying to spin zero, and one to spin one half, processes. The latter model is very closely related to phenomenological models which have been used to study off-shell effects at electromagnetic vertices.Comment: 6 pages, Latex, uses FBSsuppl.cls - Invited plenary talk at the Asia Pacific Conference on Few Body Problems in Physics, Noda/Kashiwa, Japan, August, 1999 - To be published in Few Body Systems Supp

    A Few Degrees Off the Mark: Miniature Missteps That Can Render the Safe Harbors of the DMCA Inaccessible

    Get PDF
    The term Internet Service Provider (“ISP”), as defined by the Digital Millennium Copyright Act (“DMCA”), includes virtually any online service. These services are eligible for safe harbor protections under the DMCA when they fulfill certain enumerated requirements. However, minor missteps can leave ISPs unprotected and exposed to liability for copyright infringement. This Article will discuss, through a survey of recent cases, several such mistakes made by ISPs and tips to avoid them

    A New Component in the Radio Continua of PNe

    A byproduct of experiments designed to map the CMB is the recent detection of a new component of foreground galactic emission. The anomalous foreground at 10–30 GHz, unexplained by traditional emission mechanisms, correlates with 100 mum dust emission, and is thus presumably due to dust.Is the anomalous foreground ubiquitous in the Galaxy? I will present evidence obtained with the CBI and SIMBA+SEST supporting the existence of the new component in the ISM at large, and in specific objects, in the form of a 31 GHz excess over free-free emission in PNe

    Risky Business: What Must Employers Do to Shield Against Liability for Employee Wrongdoings in the Internet Age?

    Get PDF
    Recent suits filed by the recording industry have raised the issue of employer liability for copyright infringement by employees. In fact, legal consequences for an employer do not end with copyright infringement liability, but extend into many other areas. This Article discusses several legal concerns raised by employee Internet use and examines steps an employer should take to minimize or avoid liability for inappropriate employee actions, including a discussion of benefits and drawbacks to various approaches

    Variants of the human PPARG locus and the susceptibility to chronic periodontitis

    Apart from its regulatory function in lipid and glucose metabolism, peroxisome proliferator-activated receptor (PPAR)γ has impact on the regulation of inflammation and bone metabolism. The aim of the study was to investigate the association of five polymorphisms (rs10865710, rs2067819, rs3892175, rs1801282, rs3856806) within the PPARG gene with chronic periodontitis. The study population comprised 402 periodontitis patients and 793 healthy individuals. Genotyping of the PPARG gene polymorphisms was performed by PCR and melting curve analysis. Comparison of frequency distribution of genotypes between individuals with periodontal disease and healthy controls for the polymorphism rs3856806 showed a P-value of 0.04 but failed to reach significance after correction for multiple testing (P  0.90). A 3-site analysis (rs2067819-rs1801282-rs3856860) revealed five haplotypes with a frequency of ≥1% among cases and controls. Following adjustment for age, gender and smoking, none of the haplotypes was significantly different between periodontitis and healthy controls after Bonferroni correction. This study could not show a significant association between PPARG gene variants and chronic periodontitis
