Doctrinal Antithesis in Anglo-American Administrative Law
English administrative law guards judicial supremacy over all matters of statutory interpretation, while instructing judges to refrain from scrutinizing administrators’ factual findings. By contrast, American federal courts are obliged to respect agencies’ statutory-interpretive autonomy, but take a rigorous “hard look” at substantial agency factual determinations. This Article argues that the antithetical approaches to judicial review of administrative action adopted by the apex courts of the United Kingdom and the United States can be adequately explained by the polarization of these two polities along a spectrum of effective vetogates.published_or_final_versio
The Politics of Constitutional Common Law in Hong Kong under Chinese Sovereignty
This article studies how the Hong Kong Court of Final Appeal has come to develop a sophisticated judicial gloss on the provisions of the Basic Law, Hong Kong’s constitutional document, in ways unforeseen by the Chinese National People’s Congress that enacted it. The ascendancy of constitutional common law in Hong Kong after the end of British rule is remarkable when considered in light of the continuing denial of democratic self-rule by China’s authoritarian Party-state. This article argues that the profusion of political transaction costs due to the fragmentation of the ruling elite and state-society discord consequent to the resumption of Chinese sovereignty has created the requisite space for the Court to craft, with impunity, consequential yet politically realistic doctrines bearing on such weighty matters as constitutional interpretation, central-local relations, separation of powers, and rights protection
Kinetic Evaluation of Naphthalene Removal using Acid - Modified and Unmodified Bentonite Clay Mineral
Kinetic evaluation of naphthalene onto acid – modified and unmodifiedbentonite clay mineral was investigated by means of the effects of concentration, contact time and pH. The amount of naphthalene adsorbed was determined spectrophotometrically. The optimum pH value and equilibrium contact time for the adsorption of naphthalene onto acid –modified and unmodified samples were found to be 6.0 and 30 minutes, respectively. The maximum adsorption capacity (qm) for acid – modified and unmodified adsorbents was found to be 10.52 mg/g and 5.56 mg/g. These values were close with the experimental data (qe) obtained from the adsorption of naphthalene onto acid – modified (9.0 mg/g) and unmodified (4.0 mg/g) adsorbents. The adsorption isotherm fitted well with Langmuir equation model for the acid – modified than the unmodified adsorbent. Kinetic evaluations of the adsorption showed that the process followed the pseudo – second – order equation model. The results obtained showed that modified bentonite clay mineral was reasonably effective adsorbent for the removal of naphthalene (organic contaminant), which is an important source for environmental pollutant. ©JASEMKEYWORDS: Naphthalene, equilibrium, kinetics, sorption, acid – modified bentonite.
Phonon lasing from optical frequency comb illumination of a trapped ion
An atomic transition can be addressed by a single tooth of an optical
frequency comb if the excited state lifetime () is significantly longer
than the pulse repetition period (). In the crossover regime
between fully-resolved and unresolved comb teeth (), we observe Doppler cooling of a pre-cooled trapped atomic ion
by a single tooth of a frequency-doubled optical frequency comb. We find that
for initially hot ions, a multi-tooth effect gives rise to lasing of the ion's
harmonic motion in the trap, verified by acoustic injection locking. The gain
saturation of this phonon laser action leads to a comb of steady-state
oscillation amplitudes, allowing hot ions to be loaded directly into the trap
and laser cooled to crystallization despite the presence of hundreds of
blue-detuned teeth.Comment: 5 pages, 4 figure
Gradients and anisotropies of high energy cosmic rays in the outer heliosphere
Two cosmic rays which pass through the same point going in opposite directions will, in the absence of scattering and inhomogeneities in the magnetic field, trace helices about adjacent flux tubes, whose centerlines are separated by one gyrodiameter. A directional anisotropy at the point suggests a difference in the number of cosmic rays loading the two flux tubes; that is, a density gradient over the baseline of a gyrodiameter. Previous studies at lower energies have shown that the cosmic ray density gradients vary in time and space. It is suggested that the radial gradient associated with solar cycle modulation is supported largely by narrow barriers which encircle the sun and propagate outward with the solar wind. If so, the anisotropy is a desirable way to detect spatial gradients, because it can be associated with the local solar wind and magnetic field conditions. Anisotropic measurements made by Cerenkov detectors on Pioneers 10 and 11 were studied. It was found that local anisotropy varies greatly, but that the long term average is consistent with the global radial gradient measured between two spacecraft over a baseline of many AU
