Does One Size Fit All? Should There Be a Single Set of Federal Income Tax Rules for S Corporations and Partnerships?
Suppose FIRPTA Was Repealed
This article argues, as others have before, that the Foreign Investment in Real Property Tax Act of 1980 (or “FIRPTA”), or at least the provisions of FIRPTA relating to “United States real property holding corporations,” should be repealed. Their enactment in 1980 was misguided and in any event changes in the Internal Revenue Code since then have made the provisions obsolete. But if FIRPTA is repealed, in whole or in part, the article argues that the lack of parity between foreign investment in real property that is made directly or through a partnership, on the one hand, and foreign investment in a real estate investment trust (or a regulated investment company that invests in shares of real estate investment trusts) should be dealt with. Otherwise, repeal will exacerbate existing distortions (which were already pushed further by FIRPTA) resulting from the choice of the entity used to make an investment in US real property. The article also suggests that repeal of FIRPTA would provide an opportunity to look at the taxation of foreign investment in the United States more broadly and in particular the rules that tax income from U.S. real property. The tax treatment of inward investment is a generally neglected subject. The article concludes by arguing against legislation that would keep the FIRPTA rules and simply expand provisions of present law that favor foreign investment through real estate investment trusts, such as the Real Estate Jobs and Investment Act of 2011
Can We Clean This Up? A Brief Journey Through the United States Rules for Taxing Business Entities
This article summarizes the 80-plus year history of the US federal income tax rules for classifying business entities, concluding that they result largely from administrative and/or legislative reactions to specific problems or legislative accommodations to industry lobbying efforts and do not reflect an effort to develop a comprehensive and coherent system for taxing (or not taxing) business income. While this history does not suggest that comprehensive reform is likely, the article proposes some changes that might be considered–specifically, a single tax system for non-publicly traded businesses and rationalizing the treatment of foreign investment in the US, particularly in the case of investments in stocks, securities and real estate

Tenofovir disoproxil fumarate for prevention of HIV infection in women: a phase 2, double-blind, randomized, placebo-controlled trial.
ObjectivesThe objective of this trial was to investigate the safety and preliminary effectiveness of a daily dose of 300 mg of tenofovir disoproxil fumarate (TDF) versus placebo in preventing HIV infection in women.DesignThis was a phase 2, randomized, double-blind, placebo-controlled trial.SettingThe study was conducted between June 2004 and March 2006 in Tema, Ghana; Douala, Cameroon; and Ibadan, Nigeria.ParticipantsWe enrolled 936 HIV-negative women at high risk of HIV infection into this study.InterventionParticipants were randomized 1:1 to once daily use of 300 mg of TDF or placebo.Outcome measuresThe primary safety endpoints were grade 2 or higher serum creatinine elevations (>2.0 mg/dl) for renal function, grade 3 or 4 aspartate aminotransferase or alanine aminotransferase elevations (>170 U/l) for hepatic function, and grade 3 or 4 phosphorus abnormalities (<1.5 mg/dl). The effectiveness endpoint was infection with HIV-1 or HIV-2.ResultsStudy participants contributed 428 person-years of laboratory testing to the primary safety analysis. No significant differences emerged between treatment groups in clinical or laboratory safety outcomes. Study participants contributed 476 person-years of HIV testing to the primary effectiveness analysis, during which time eight seroconversions occurred. Two were diagnosed in participants randomized to TDF (0.86 per 100 person-years) and six in participants receiving placebo (2.48 per 100 person-years), yielding a rate ratio of 0.35 (95% confidence interval = 0.03-1.93), which did not achieve statistical significance. Owing to premature closures of the Cameroon and Nigeria study sites, the planned person-years of follow-up and study power could not be achieved.ConclusionDaily oral use of TDF in HIV-uninfected women was not associated with increased clinical or laboratory adverse events. Effectiveness could not be conclusively evaluated because of the small number of HIV infections observed during the study
Water at an electrochemical interface - a simulation study
The results of molecular dynamics simulations of the properties of water in
an aqueous ionic solution close to an interface with a model metallic electrode
are described. In the simulations the electrode behaves as an ideally
polarizable hydrophilic metal, supporting image charge interactions with
charged species, and it is maintained at a constant electrical potential with
respect to the solution so that the model is a textbook representation of an
electrochemical interface through which no current is passing. We show how
water is strongly attracted to and ordered at the electrode surface. This
ordering is different to the structure that might be imagined from continuum
models of electrode interfaces. Further, this ordering significantly affects
the probability of ions reaching the surface. We describe the concomitant
motion and configurations of the water and ions as functions of the electrode
potential, and we analyze the length scales over which ionic atmospheres
fluctuate. The statistics of these fluctuations depend upon surface structure
and ionic strength. The fluctuations are large, sufficiently so that the mean
ionic atmosphere is a poor descriptor of the aqueous environment near a metal
surface. The importance of this finding for a description of electrochemical
reactions is examined by calculating, directly from the simulation, Marcus free
energy profiles for transfer of charge between the electrode and a redox
species in the solution and comparing the results with the predictions of
continuum theories. Significant departures from the electrochemical textbook
descriptions of the phenomenon are found and their physical origins are
characterized from the atomistic perspective of the simulations.Comment: 29 pages, 15 figure
