NO(political) identity, NO(political)information, NO VOTE: the decline of electoral turnout among young voters in Britain
This thesis examines the extent of turnout decline at general elections since 1992. Its first contribution is to reveal that turnout decline amongst the youngest age groups was significantly more pronounced in the period 1992-2001 than for other age groups. The central argument is that there are sufficient grounds for suspecting that life-cycle factors cannot alone account for the unprecedented decline in turnout between 1992 and 2001,
and that generational factors may be at work. The second contribution of the thesis is to test a variety of explanatory models of political participation on these youngest groups to ascertain if the results provide any insights of the dynamics of a suspected generational change. The thesis argues that a weakening of the psychological anchors to social and political life have left recent generations exposed and more susceptible than
their older counterparts to factors that have been shown to decrease the likelihood of voting such as weakness of electoral competition; little perceived difference between political parties and an environment of negative images of politics and politicians

Methods of Legal Education
My opinion is asked in respect to the methods of legal instruction. I am not an authority upon that subject. My connection with it has been too limited and too brief to entitle any conclusions of mine to be placed in comparison with those of gentlemen who by long and honourable service have attained a distinguished reputation in that important field. Such views as I have, are not derived from consideration of systems of study, but from observation of their results. I have paid little attention to the processes of culture, but have had large opportunities to observe the harvest, for my acquaintance with the profession in all its grades has been long and wide
Turbulence spectra in the wind immediately over a water surface
In order to understand more fully the wind generation of water waves, the oceanographer should have a better knowledge of the turbulence structure of the wind field immediately above a water surface. Measurements of atmospheric turbulence about three inches above the surface of a lake, using a hot-wire anemometer, were made. The analog signals were recorded as DC voltages on a magnetic tape recorder. The analog data were converted to digital form to permit subsequent computation of power spectral densities using a high-speed digital computer. Average power spectral densities from 0 to 20, 0 to 500, and 0 to 1000 cps, respectively, are presented.http://archive.org/details/turbulencespectrphelLieutenant Commander, United States NavyApproved for public release; distribution is unlimited
Tools and terms for understanding illegal wildlife trade
Illegal wildlife trade (IWT) is a global conservation issue that threatens thousands of species, including fish, fungi, medicinal plants, and charismatic mammals. Despite widespread recognition of the problem, debates on the science and policy of IWT generally concentrate on a few high- profile species (eg rhinoceros, tigers, elephants) and often overlook or conflate complex IWT products, actors, networks, and contexts. A poor understanding of IWT is aggravated by the lack of systematic vocabulary and conceptual tools with which to analyze complex phenomena in a more structured way. We synthesize the available evidence on IWT across taxa and contexts into a typology- based framework that considers (1) the diversity of wildlife products; (2) the roles of various actors involved with IWT, including harvesters, intermediaries, and consumers; and (3) common IWT network configurations. We propose ways in which these tools can inform structured analyses of IWT, to help ensure more nuanced, appropriate, targeted, and effective responses to illegal wildlife harvest, trade, and use
Numerical action reconstruction of the dynamical history of dark matter haloes in N-body simulations
We test the ability of the numerical action method (NAM) to recover the
individual orbit histories of mass tracers in an expanding universe in a region
of radius 26Mpc/h, given the masses and redshift-space coordinates at the
present epoch. The mass tracers are represented by dark matter haloes
identified in a high resolution N-body simulation of the standard LCDM
cosmology. Since previous tests of NAM at this scale have traced the underlying
distribution of dark matter particles rather than extended haloes, our study
offers an assessment of the accuracy of NAM in a scenario which more closely
approximates the complex dynamics of actual galaxy haloes. We show that NAM can
recover present-day halo distances with typical errors of less than 3 per cent,
compared to 5 per cent errors assuming Hubble flow distances. The total halo
mass and the linear bias were both found to be constained at the 50 per cent
level. The accuracy of individual orbit reconstructions was limited by the
inability of NAM, in some instances, to correctly model the positions of haloes
at early times solely on the basis of the redshifts, angular positions, and
masses of the haloes at the present epoch. Improvements in the quality of NAM
reconstructions may be possible using the present-day three-dimensional halo
velocities and distances to further constrain the dynamics. This velocity data
is expected to become available for nearby galaxies in the coming generations
of observations by SIM and GAIA.Comment: 12 pages, 9 figures. submitted to MNRA

Formalizing artisanal and small-scale gold mining : A grand challenge of the Minamata Convention
Artisanal and small-scale gold mining (ASGM) is the world's largest source of anthropogenic mercury emissions and releases. These have devastating consequences for miners' health and the environment. Most of the >20 million ASGM miners worldwide are not officially recognized, registered, regulated, or protected by state laws. Formalization-the process of organizing, registering, and reforming ASGM-is mandated by the Minamata Convention on Mercury. Previous attempts to reduce mercury emissions from ASGM have largely failed. Our perspective argues that signatories to the Convention will only succeed in reducing ASGM mercury emissions and releases with comprehensive bottom-up formalization approaches centered around working with miners, and significant external funding from consumers, large mining corporations, and governments. The approximate global 5-year cost of this approach could be US213-742 million) if scaled per country, or US248 million-US$2.17 billion) if scaled per miner.Peer reviewe
