(Supplementary Table 1) Iceberg-rafted debris (IBRD) mass accumulation rates (MAR) of IODP site 318-U1361

The Pliocene and Early Pleistocene, between 5.3 and 0.8 million years ago, span a transition from a global climate state that was 2-3 °C warmer than present with limited ice sheets in the Northern Hemisphere to one that was characterized by continental-scale glaciations at both poles. Growth and decay of these ice sheets was paced by variations in the Earth's orbit around the Sun. However, the nature of the influence of orbital forcing on the ice sheets is unclear, particularly in light of the absence of a strong 20,000-year precession signal in geologic records of global ice volume and sea level. Here we present a record of the rate of accumulation of iceberg-rafted debris offshore from the East Antarctic ice sheet, adjacent to the Wilkes Subglacial Basin, between 4.3 and 2.2 million years ago. We infer that maximum iceberg debris accumulation is associated with the enhanced calving of icebergs during ice-sheet margin retreat. In the warmer part of the record, between 4.3 and 3.5 million years ago, spectral analyses show a dominant periodicity of about 40,000 years. Subsequently, the powers of the 100,000-year and 20,000-year signals strengthen. We suggest that, as the Southern Ocean cooled between 3.5 and 2.5 million years ago, the development of a perennial sea-ice field limited the oceanic forcing of the ice sheet. After this threshold was crossed, substantial retreat of the East Antarctic ice sheet occurred only during austral summer insolation maxima, as controlled by the precession cycle.

Architectural guidelines for the Curricula: 3 Layers, 3 New Dimensions, 2 Basic Orientations, Different levels in the Topics

Today, designing informatics curricula is a major problem. As a technology, informatics is experiencing a dramatic evolution, with its rapidly expanding areas of application and everincreasing impact on society. At first glance, it seems that if we might need several different curricula for facing very different practical educational situations, and not just one or two curricula. The current deep discrepancies among some of our more prestigious computer scientists in relation to the focus of informatics education are in fact a form of recognition of this necessity and at the same time, proof we are at a turning point.

Evaluación de la fuerza en niños de educación infantil (3-5 años) proyecto PREFIT

Introducción: El proyecto de investigación PREFIT (field – based FITness testing in PREschool children) ha diseñado una batería de tests de campo fiables y válidos para evaluar la condición física en niños preescolares (3 a 5 años), siendo la fuerza uno de los componentes más importantes de la condición física. La fuerza muscular se considera un importante marcador de salud cardiovascular y osteoarticular en niños, además de contribuir a su salud mental. Por tanto, la evaluación y mejora de esta cualidad desde etapas tempranas es crucial para el desarrollo saludable de los niños.

3.5 S. Woodson Canada, University of Missouri Registra

Although Canada did not have the ultimate authority to reject Gaines’ application, the chances for Lloyd were bleak; it appeared that the School of Law at MU would not accept him.

3.5 Supreme Court Justice James P. McReynolds

However, there was an obstacle on the court, namely James Clark McReynolds, an avowed racist. In fact, during the hearing, McReynolds turned his chair around and faced the wall when Houston presented his argument.
