Amyotrophic lateral sclerosis and Parkinsonism-dementia complex of Guam: Descriptive epidemiology, secular trends, and birth cohort effects on incidence, 1950--1989

This study describes the patterns of occurrence of amyotrophic lateral sclerosis (ALS) and parkinsonism-dementia complex (PDC) of Guam during 1950-1989. Both ALS and PDC occur with high frequency among the indigenous Chamorro population, first recognized in the early 1950's. Reports in the early 1980's indicated that both ALS and PDC were disappearing, due to a purported reduction in exposure to harmful environmental factors as a result of the dramatic changes in lifestyle that took place after World War II. However, this study provides compelling evidence that ALS and PDC have not disappeared on Guam and that rates for both are higher during 1980-1989 than previously reported.^ The patterns of occurrence for both ALS and PDC overlap in most respects: (1) incidence and mortality are decreasing; (2) median age at onset is increasing; (3) males are at increased risk for developing disease; (4) risk is higher for those residing in the south compared to the non-south; and (5) age-specific incidence is decreasing over time except in the oldest age groups.^ Age-specific incidence of ALS and PDC, separately and together, is generally higher for cohorts born before 1920 than for those born after 1920. A significant birth cohort effect on the incidence of PDC for the 1906-1915 birth cohort was found, but not for ALS and for ALS and PDC together. Whether or not a cohort effect, period effect, or both are associated with incidence of ALS and PDC cannot be determined from the data currently available and will require additional follow-up of individuals born after 1920.^ The epidemiological data amassed over this 40-year period provide evidence that supports an environmental exposure model for disease occurrence as opposed to a simple genetic or infectious disease model. Whether neurodegenerative disease in this population occurs as a consequence of a single exposure or is explained by a multifactorial model such as a genetic predisposition with some environmental interaction is yet to be determined. However, descriptive studies such as this can provide clues concerning timing and location of potential adverse exposures but cannot determine etiology, underscoring the urgent need for analytic studies of ALS and PDC to further investigate existing etiologic hypotheses and to test new hypotheses. ^

Time variable Earth’s gravity field from SLR satellites

The time variable Earth’s gravity field contains information about the mass transport within the system Earth, i.e., the relationship between mass variations in the atmosphere, oceans, land hydrology, and ice sheets. For many years, satellite laser ranging (SLR) observations to geodetic satellites have provided valuable information of the low-degree coefficients of the Earth’s gravity field. Today, the Gravity Recovery and Climate Experiment (GRACE) mission is the major source of information for the time variable field of a high spatial resolution. We recover the low-degree coefficients of the time variable Earth’s gravity field using SLR observations up to nine geodetic satellites: LAGEOS-1, LAGEOS-2, Starlette, Stella, AJISAI, LARES, Larets, BLITS, and Beacon-C. We estimate monthly gravity field coefficients up to degree and order 10/10 for the time span 2003–2013 and we compare the results with the GRACE-derived gravity field coefficients. We show that not only degree-2 gravity field coefficients can be well determined from SLR, but also other coefficients up to degree 10 using the combination of short 1-day arcs for low orbiting satellites and 10-day arcs for LAGEOS-1/2. In this way, LAGEOS-1/2 allow recovering zonal terms, which are associated with long-term satellite orbit perturbations, whereas the tesseral and sectorial terms benefit most from low orbiting satellites, whose orbit modeling deficiencies are minimized due to short 1-day arcs. The amplitudes of the annual signal in the low-degree gravity field coefficients derived from SLR agree with GRACE K-band results at a level of 77 %. This implies that SLR has a great potential to fill the gap between the current GRACE and the future GRACE Follow-On mission for recovering of the seasonal variations and secular trends of the longest wavelengths in gravity field, which are associated with the large-scale mass transport in the system Earth.

Root system of singular perturbations of the harmonic oscillator type operators

We analyze perturbations of the harmonic oscillator type operators in a Hilbert space H, i.e. of the self-adjoint operator with simple positive eigenvalues μ k satisfying μ k+1 − μ k ≥ Δ > 0. Perturbations are considered in the sense of quadratic forms. Under a local subordination assumption, the eigenvalues of the perturbed operator become eventually simple and the root system contains a Riesz basis.

Working with A Secular Age. Interdisciplinary Perspectives on Charles Taylor's Master Narrative

Charles Taylor’s monumental book A Secular Age has been extensively discussed, criticized, and worked on. This volume, by contrast, explores ways of working with Taylor’s book, especially its potentials and limits for individual research projects. Due to its wide reception, it has initiated a truly interdisciplinary object of study; with essays drawn from various research fields, this volume fosters substantial conversation across disciplines.

The Secular State Under Siege: Religion and Politics in Europe and America

Throughout human history, religion and politics have entertained the most intimate of connections as systems of authority regulating individuals and society. While the two have come apart through the process of secularization, secularism is challenged today by the return of public religion. This cogent analysis unravels the nature of the connection, disconnection, and attempted reconnection between religion and politics in the West. In a comparison of Western Europe and North America, Christianity and Islam, Joppke advances far-reaching theoretical, historical, and comparative-political arguments. With respect to theory, it is argued that only a “substantive” concept of religion, as pertaining to the existence of supra-human powers, opens up the possibility of a historical-comparative perspective on religion. At the level of history, secularization is shown to be the distinct outcome of Latin Christianity itself. And at the level of comparative politics, the Christian Right in America which has attacked the “wall of separation” between religion and state and Islam in Europe with the controversial insistence on sharia law and other “illiberal” claims from some quarters are taken to be counterpart incarnations of public religion and challenges to the secular state. This clearly argued, sweeping book will provide an invaluable framework for approaching an array of critical issues at the intersection of religion, law and politics for advanced students and researchers across the social sciences and legal studies, as well as for the interested public.

Reseña del libro : Combatientes de Perón, herederos de Cristo. Peronismo, religión secular y organizaciones de cuadros, de Humberto Cucchetti

El presente texto es un resumen del libro recientemente publicado por Prometeo del investigador Humberto Cucchetti titulado "Combatientes de Perón, herederos de Cristo. Peronismo, religión secular y organizaciones de cuadros". El cual es el resultado de la Tesis Doctoral del autor defendida en 2007 (Universidad de Buenos Aires-Ecole des Hautes en Sciences Sociales). Lo que el autor desarrolla son las trayectorias individuales y organizacionales de los militantes de la Organización Única de Trasvasamiento Generacional (OUTG)) entramado organizativo donde confluyeron Guardia de Hierro (histórica organización de la resistencia peronista) y el Frente Estudiantil Nacional (FEN) (surgido a fines de los sesenta producto de la peronización del estudiantado). El período que abarca su análisis va desde el origen de estas organizaciones hasta su desaparicón en la década del noventa
