Resale Price Maintenance After Monsanto: A Doctrine Still at War With Itself

In this article, two enforcement officials at the Federal Trade Commission reexamine resale price maintenance in light of the Supreme Court\u27s recent decision in Monsanto Co. v. Spray-Rite Service Corp. Commissioner Calvani and Mr. Berg consider both antitrust law and economic policy in their review of the history of resale price maintenance; they point out the chronic inconsistencies to which this antitrust regime has been subject, and identify these same inconsistencies at work in Monsanto. The authors set forth three theses with respect to Monsanto: first, that the Court intimated a willingness to reconsider at some future time the per se standard of illegality for resale price maintenance; second, that the Court recognized the continuing vitality of the Colgate doctrine, which had been seriously questioned in recent years; and, third, that the Monsanto Court unsuccessfully attempted to delineate a workable evidentiary standard applicable to communications between sellers and resellers when it is alleged that such communications constitute an illegal contract, combination, or conspiracy under section one of the Sherman Act. The authors suggest that, taken together, these elements in Monsanto display a doctrine at war with itself. The authors conclude by examining the possible implications of the Monsanto decision for the future direction of the law of resale price maintenance

Microspine Gripping Mechanism for Asteroid Capture

This paper details the development and early testing of a compliant suspension for a microspine gripper device for asteroid capture or micro-gravity percussive drilling. The microspine gripper architecture is reviewed, and a proposed microspine suspension design is presented and discussed. Prototyping methods are discussed, as well as testing methods and results. A path forward is identified from the results of the testing completed thus far. Key findings include: the microspine concept has been established as a valid architecture and the compliant suspension exhibits the desired stiffness characteristics for good gripping behavior. These developments will aid in developing the capability to grasp irregularly shaped boulders in micro-gravity

Redistribución, desigualdad y crecimiento

This paper takes advantage of a recently-compiled cross-country dataset that distinguishes market inequality from net inequality and allows us to calculate redistributive transfers for a large number of country-year observations. Our main findings are: 1. More unequal societies tend to redistribute more. 2. Lower net inequality is robustly correlated with faster and more durable growth, for a given level of redistribution. 3. R edistribution appears generally benign in terms of its impact on growth; only in extreme cases is there some evidence that it may have direct negative effects on growth. Thus the combined direct and indirect effects of redistribution –including the growth effects of the resulting lower inequality– are on average pro-growth. While we should be cognizant of the inherent limitations of the data set and of cross-country regression analysis more generally, we should be careful not to assume that there is a big tradeoff between redistribution and growth. The best available macroeconomic data do not support that conclusion.Este artículo emplea un conjunto de datos reciente que distingue entre desigualdad neta y de mercado, y permite calcular las transferencias redistributivas anuales de un gran número de países. Las principales conclusiones son: 1. Sociedades más desiguales tienden a redistribuir más. 2. Una menor desigualdad neta se correlaciona robustamente con un crecimiento más rápido y más durable, dado un nivel de redistribución. 3. El impacto de la redistribución sobre el crecimiento parece ser benigno en general, y hay evidencia de que solo en casos extremos puede tener efectos negativos. Por tanto, sus efectos conjuntos, directos e indirectos –incluidos los efectos de la menor desigualdad resultante–, son favorables al crecimiento. Pese a las limitaciones inherentes al conjunto de datos y al análisis de regresión, no se puede suponer que hay un gran trade-off entre redistribución y crecimiento; los mejores datos macroeconómicos disponibles no respaldan esa hipótesis

A Three Dimensional Analysis of Au-Silica Core-Shell Nanoparticles Using Medium Energy Ion Scattering

The medium energy ion scattering (MEIS) facility at the IIAA Huddersfield has been used for the analysis of a monolayer of Au-silica core-shell nanoparticles deposited on Si substrate. Both spherical and rod shape particles were investigated and the spectra produced by 100 keV He+ ions scattered through angles of 90º and 125º were compared with the results of RBS-MAST [1] simulations performed on artificial 3D model cells containing the nanoparticles. The thickness of the silica shell, the diameter of the Au spheres, and the diameter and length of the Au nano-rods were determined from best fits of the measured set of MEIS spectra. In addition, the effect of ion irradiation on the silica shell and gold core was monitored by MEIS measurements in conjunction with RBS-MAST simulations. Ion bombardment was performed under largely different conditions, i.e., by 30 keV Ar+, 150 keV Fe+, or 2.8 MeV N+ ions in the dose range of 2×1015 - 2×1016 cm-2. Significant changes in the particle geometry can be observed due to ion beam-induced sputtering and recoil effects, the significance of which was estimated from full-cascade SRIM simulations. Rutherford backscattering spectrometry (RBS), Field emission scanning electron microscopy (FESEM), and Atomic Force Microscopy (AFM) techniques have been applied as complementary characterization tools to monitor the amount of gold and surface morphology on the un-irradiated and irradiated sample areas. We show that MEIS can yield spatial information on the geometrical changes of particulate systems at the nanometre scale

Cosmological perturbations in Massive Gravity and the Higuchi bound

In de Sitter spacetime there exists an absolute minimum for the mass of a spin-2 field set by the Higuchi bound m^2 \geq 2H^2. We generalize this bound to arbitrary spatially flat FRW geometries in the context of the recently proposed ghost-free models of Massive Gravity with an FRW reference metric, by performing a Hamiltonian analysis for cosmological perturbations. We find that the bound generically indicates that spatially flat FRW solutions in FRW massive gravity, which exhibit a Vainshtein mechanism in the background as required by consistency with observations, imply that the helicity zero mode is a ghost. In contradistinction to previous works, the tension between the Higuchi bound and the Vainshtein mechanism is equally strong regardless of the equation of state for matter.Comment: 24 pages, typos and conventions correcte

HIV Continuum of Care for Youth in the United States

BACKGROUND: Beneficial HIV treatment outcomes require success at multiple steps along the HIV Continuum of Care. Youth living with HIV are a key population, and sites in the Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN) are known for modeling optimum HIV adolescent care. METHODS: A longitudinal cohort study conducted at 14 network sites across the United States assessed how the later steps of the Continuum of Care were achieved among the youth: engagement, treatment, and viral load (VL) suppression. Youth aged 13-24 who were behaviorally infected with HIV and linked to care at an ATN-affiliated site were eligible to participate. RESULTS: A total of 467 youth were enrolled and had 1 year of available data. Most were aged 22-24 (57%), male (79%), and black/non-Hispanic (71%). Most used alcohol (81%) and marijuana (61%) in the 3 months before enrollment, and 40% had a history of incarceration. Among this cohort of youth, 86% met criteria for care engagement; among these, 98% were prescribed antiretroviral therapy and 89% achieved VL suppression. Sustained VL suppression at all measured time points was found among 59% with initial suppression. Site characteristics were notable for the prevalence of adherence counseling (100%), case management (100%), clinic-based mental health (93%), and substance use (64%) treatment. CONCLUSIONS: Youth living with HIV in the United States can be successfully treated at health care sites with experience, excellence, and important resources and services. Sustained VL suppression may be an important step to add to the Continuum of Care for youth

Rheumatoid synovial fluid interleukin-17-producing CD4 T cells have abundant tumor necrosis factor-alpha co-expression, but little interleukin-22 and interleukin-23R expression

Introduction\ud Th17 cells have been implicated in the pathogenesis of rheumatoid arthritis (RA). The aim of this study was to systematically analyse the phenotype, cytokine profile and frequency of interleukin-17 (IL-17) producing CD4-positive T cells in mononuclear cells isolated from peripheral blood, synovial fluid and synovial tissue of RA patients with established disease, and to correlate cell frequencies with disease activity. \ud \ud Methods\ud Flow cytometry was used to analyse the phenotype and cytokine production of mononuclear cells isolated from peripheral blood (PBMC) (n = 44), synovial fluid (SFMC) (n = 14) and synovium (SVMC) (n = 10) of RA patients and PBMC of healthy controls (n = 13). \ud \ud Results\ud The frequency of IL-17-producing CD4 T cells was elevated in RA SFMC compared with RA PBMC (P = 0.04). However, the frequency of this population in RA SVMC was comparable to that in paired RA PBMC. The percentage of IL-17-producing CD4 T cells coexpressing tumor necrosis factor alpha (TNFα) was significantly increased in SFMC (P = 0.0068). The frequency of IFNγ-producing CD4 T cells was also significantly higher in SFMC than paired PBMC (P = 0.042). The majority of IL-17-producing CD4 T cells coexpressed IFNγ. IL-17-producing CD4 T cells in RA PBMC and SFMC exhibited very little IL-22 or IL-23R coexpression. \ud \ud Conclusions\ud These findings demonstrate a modest enrichment of IL-17-producing CD4 T cells in RA SFMC compared to PBMC. Th17 cells in SFMC produce more TNFα than their PBMC counterparts, but are not a significant source of IL-22 and do not express IL-23R. However, the percentage of CD4 T cells which produce IL-17 in the rheumatoid joint is low, suggesting that other cells may be alternative sources of IL-17 within the joints of RA patients. \ud \u
