The Role of Licence-Exemption in Spectrum Reform

Spectrum reform initiatives in the US and Europe have identified a need to move away from the traditional command and control approach towards flexible and tradable licences and licence-exemption. Current regulatory initiatives are tending to focus on the flexible licensing route, and there is a risk that licence-exemption will be sidelined during the important formative years of this major policy transition. This must not happen; licence-exemption supports innovation and entrepreneurship and is an important second leg of a market-based spectrum management regime. A current case in point is the transition in UHF frequency bands from analogue to digital TV, where licence exempt use of resulting gaps in the spectrum could yield enormous benefits for citizens and consumers.spectrum policy, spectrum management, wireless services, deregulation, Telecommunications, regulation, Networks

Speaking of clans: language in Awyu-Ndumut communities of Indonesian West Papua

The place of language in Awyu-Ndumut speech communities of the Indonesian province of West Papua is investigated from the point of view of the parallel but interconnected worlds of clan lands and nation-state sponsored settlements, with institutions such as schools and churches. First, language and identity, language names, multilingualism, linguistic ideologies and special speech registers are discussed from the perspective of clan-based cultural and linguistic practices. Second, the relationship between Papuan languages and Indonesian is investigated from the perspective of the dynamics of the clan land/settlement opposition. Indonesian is talked about by Awyu-Ndumut speakers both positively and negatively. Positively, they speak of it as an interethnic lingua franca. Negatively, they speak of it as the language of "demons", that is people outside the boundaries of Awyu-Ndumut social personhood

The Effects of Low Temperature Cooking on the Deinking of Groundwood

An experiment was designed to lower the temperature of the cooking stage in the deinking of groundwood. The cook chemicals consisted of sodium meta-silicate, sodium carbonate, hydrogen peroxide and surfactants. The pulp was cooked over a temperature of 50°F-130°F. The pulp was washed on a laboratory sidehill screen and brightness pads were made. The object of the experiment was to reduce the cook temperature and use additional surfactant to maintain the brightness. Maximum brightness values were found a 0.1% surfactant and 110°F, and 0.3% surfactant and 90°F. A cost analysis revealed that a system can operate at slightly elevated temperatures and low surfactant level. This type of system is more economically feasible than operating at low temperatures and higher surfactant level. Keywords: Deinking, washing, secondary fiber, newsprin

Four-Quark Effective Operators at Hadron Colliders

The robustness of translating effective operator constraints to BSM theories crucially depends on the mass and coupling of BSM particles. This is especially relevant for hadron colliders where the partonic centre of mass energy is around the typical energy scales of natural BSM theories. The caveats in applying the limits are discussed using Z' and G' models, illustrating the effects for a large class of models. This analysis shows that the applicability of effective operators mainly depends on the ratio of the transfer energy in the events and the mass scale of the full theory. Moreover, based on these results a method is developed to recast existing experimental limits on four-quark effective operators to the full theory parameter space.Comment: 28 pages, 10 figures, version 2 updated to JHEP 03 (2015) 09
