Why Limits on Contributions to Super PACs Should Survive \u3ci\u3eCitizens United\u3c/i\u3e
Soon after the Supreme Court decided Citizens United v. FEC, the D.C. Circuit held all limits on contributions to super PACs unconstitutional. Its decision in SpeechNow.org v. FEC created a regime in which contributions to candidates are limited but in which contributions to less responsible groups urging votes for these candidates are unbounded. No legislator voted for this system of campaign financing, and the judgment that the Constitution requires it is astonishing. Forty-two years ago, Buckley v. Valeo held that Congress could limit contributions to candidates because these contributions are corrupting or create an appearance of corruption. According to the D.C. Circuit, however, Congress may not prohibit multi-million-dollar contributions to satellite campaigns because these contributions do not create even an appearance of corruption. The D.C. Circuit said that a single sentence of the Citizens United opinion compelled its result. It wrote, “In light of the Court’s holding as a matter of law that independent expenditures do not corrupt or create the appearance of corruption, contributions to groups that make only independent expenditures also cannot corrupt or create the appearance of corruption.” This Article contends that, contrary to the D.C. Circuit’s reasoning, contributions to super PACs can corrupt even when expenditures by these groups do not. Moreover, the statement that the D.C. Circuit took as its premise was dictum, and the Supreme Court did not mean this statement to be taken in the way the D.C. Circuit took it. The Supreme Court’s long-standing distinction between contribution limits and expenditure limits does not rest on the untenable proposition thatcandidates cannot be corrupted by funds paid to and spent on their behalf by others. Rather, Buckley noted five differences between contributions and expenditures. A review of these differences makes clear that contributions to super PACs cannot be distinguished from the contributions to candidates whose limitation the Court upheld. The ultimate question posed by Buckley is whether super PAC contributions create a sufficient appearance of corruption to justify their limitation. This Article reviews the statements of candidates of both parties in the 2016 presidential election, the views of Washington insiders, and public opinion polls. It shows that SpeechNow has sharpened class divisions and helped to tear America apart. The Justice Department did not seek Supreme Court review of the SpeechNow decision. In a statement that belongs on a historic list of wrong predictions, Attorney General Holder explained that the decision would “affect only a small subset of federally regulated contributions.” Although eight years have passed since SpeechNow, the Supreme Court has not decided whether the Constitution guarantees the right to give unlimited funds to super PACs. A final section of this Article describes the efforts of members of Congress and candidates for Congress to bring that question before the Court. The Federal Election Commission is opposing their efforts, offering arguments that, if accepted, would be likely to keep the Court from ever deciding the issue
Realization of an Interacting Two-Valley AlAs Bilayer System
By using different widths for two AlAs quantum wells comprising a bilayer
system, we force the X-point conduction-band electrons in the two layers to
occupy valleys with different Fermi contours, electron effective masses, and
g-factors. Since the occupied valleys are at different X-points of the
Brillouin zone, the interlayer tunneling is negligibly small despite the close
electron layer spacing. We demonstrate the realization of this system via
magneto-transport measurements and the observation of a phase-coherent, bilayer
=1 quantum Hall state flanked by a reentrant insulating phase.Comment: 5 page
Lupus nephritis. Part I. Histopathological classification, activity and chronicity scores
CITATION: Bates, W. D. et al. 1991. Lupus nephritis. Part I. Histopathological classification, activity and chronicity scores. South African Medical Journal, 79:256-259.The original publication is available at http://www.samj.org.zaRenal biopsy has made a major contribution to the understanding and management of patients with lupus nephritis. In a 5-year retrospective study the renal morphology of 55 biopsies from 51 patients with lupus nephritis was classified acccrding to World Health Organisation criteria. In addition, semi-quantitative activity and chronicity scores were documented. The findings were similar to series from other parts of the world. Of the biopsies reviewed, 6 were class II, 13 class III, 32 class IV and 4 class V. In situations of overlap, segmental proliferative features determined the class to which a biopsy specimen was assigned. Twenty-five of the patients, all WHO class IV, showed activity scores in the severe range. Most of the activity score features were common and easily recognised but necrotising angiitis was only seen in 1 patient. Haematoxylin bodies were difficult to document and the nature and value of the haematoxylin body is questioned.Publisher’s versio
Lupus nephritis. Part II. A clinicopathological correlation and study of outcome
CITATION: Halland, A.-M. et al. 1991. Lupus nephritis. Part II. A clinicopathological correlation and study of outcome. South African Medical Journal, 79:260-264.The original publication is available at http://www.samj.org.zaA 5-year retrospective study of lupus nephritis at Tygerberg Hospital was performed in an attempt to document the clinical and histological spectrum of the disease and to study the outcome of the illness. Activity and chronicity scores were used in addition to the World Health Organisation classification system. Of 55 biopsies from 51 patients reviewed, 6 were class II, 13 class III, 32 class IV and 4 class V. There were 19 deaths and in 15 of these the histological classification was IV. Renal failure and infections, often with uncommon pathogens, were the most important causes of death. Serum creatinine values and creatinine clearance at the time of biopsy or follow-up, and hypertension at follow-up showed a significant relationship with outcome. WHO class IV was associated with a poor outcome (P= 0,048) when compared with the other WHO classes combined. Activity scores showed a significant relationship to the outcome (P = 0,018). The anticardiolipin antibodies IgG and IgM were not associated with WHO class or outcome. The study revealed a spectrum of histological results similar to that of other studies, with a high mortality rate, particularly in class IV disease. Poor renal function, persistent hypertension, histological classification IV, and high activity scores were found to be important prognostic indicators.Publisher’s versio

Unusual conductance collapse in one-dimensional quantum structures
We report an unusual insulating state in one-dimensional quantum wires with a
non-uniform confinement potential. The wires consist of a series of closely
spaced split gates in high mobility GaAs/AlGaAs heterostructures. At certain
combinations of wire widths, the conductance abruptly drops over three orders
of magnitude, to zero on a linear scale. Two types of collapse are observed,
one occurring in multi-subband wires in zero magnetic field and one in single
subband wires in an in-plane field. The conductance of the wire in the collapse
region is thermally activated with an energy of the order of 1 K. At low
temperatures, the conductance shows a steep rise beyond a threshold DC
source-drain voltage of order 1 mV, indicative of a gap in the density of
states. Magnetic depopulation measurements show a decrease in the carrier
density with lowering temperature. We discuss these results in the context of
many-body effects such as charge density waves and Wigner crystallization in
quantum wires.Comment: 5 pages, 5 eps figures, revte
Uncoupled excitons in semiconductor microcavities detected in resonant Raman scattering
We present an outgoing resonant Raman-scattering study of a GaAs/AlGaAs based microcavity embedded in a p-i-n junction. The p-i-n junction allows the vertical electric field to be varied, permitting control of exciton-photon detuning and quenching of photoluminescence which otherwise obscures the inelastic light scattering signals. Peaks corresponding to the upper and lower polariton branches are observed in the resonant Raman cross sections, along with a third peak at the energy of uncoupled excitons. This third peak, attributed to disorder activated Raman scattering, provides clear evidence for the existence of uncoupled exciton reservoir states in microcavities in the strong-coupling regime
Effect of deconfinement on resonant transport in quantum wires
The effect of deconfinement due to finite band offsets on transport through
quantum wires with two constrictions is investigated. It is shown that the
increase in resonance linewidth becomes increasingly important as the size is
reduced and ultimately places an upper limit on the energy (temperature) scale
for which resonances may be observed.Comment: 6 pages, 6 postscript files with figures; uses REVTe
