Dance – a healthy gateway to STEAM practice

A rumination on dance and STEA

Job Management and Task Bundling

High Performance Computing is often performed on scarce and shared computing resources. To ensure computers are used to their full capacity, administrators often incentivize large workloads that are not possible on smaller systems. Measurements in Lattice QCD frequently do not scale to machine-size workloads. By bundling tasks together we can create large jobs suitable for gigantic partitions. We discuss METAQ and mpi_jm, software developed to dynamically group computational tasks together, that can intelligently backfill to consume idle time without substantial changes to users' current workflows or executables.Comment: 8 pages, 3 figures, LATTICE 2017 proceeding

Asset Prices in a Time Series Model with Perpetually Disparately Informed, Competitive Traders

This paper develops a dynamic asset pricing model with persistent heterogeneous beliefs. The model features competitive traders who receive idiosyncratic signals about an underlying fundamentals process. We adapt Futia’s (1981) frequency domain methods to derive conditions on the fundamentals that guarantee noninvertibility of the mapping between observed market data and the underlying shocks to agents’ information sets. When these conditions are satisfied, agents must ‘forecast the forecasts of others’. The paper provides an explicit analytical characterization of the resulting higher-order belief dynamics. These additional dynamics can explain apparent violations of variance bounds and rejections of cross-equation restrictions.Asymmetric Information, Blaschke Factors

A study of the dissociation of calcium hydride

The calcium hydride equilibrium has been investigated by a number of men but the results obtained have been almost as diversified as the the number of workers. There is considerable doubt as to the mechanism of the dissociation and the compounds formed. Some workers claim evidence of the two hydrides while others found only the normal hydride, CaH2. In most of the previous work, the equilibrium has been more or less disturbed by the volatility of the calcium and the hydride and also the reaction of the calcium or the hydride on the quartz containers. In this work an attempt has been made to overcome these difficulties by enclosing the solids in an iron or nickel cylinder which is permeable to hydrogen gas at the temperatures of the dissociation. This should give more accurate hydrogen pressures which is a measure of the progress of the reaction since it is the only gaseous component. This method can also be applied to the measurement of dissociation of the hydrides of barium and strontium

The theological and doxological understanding of resurrection: an examination of its centrality within the 4th century Christian orthodox understanding of Easter with particular reference to the festal letters of St. Athanasius of Alexandria

The Festal Letters of Saint Athanasius were composed in response to a decision by the Ecumenical Council of Nicaea in 325 AD. The Council of Bishops assembled primarily to confront the teachings of Arianism, which had questioned the Nature and Person of Jesus Christ. But another problem that the Council of Nicaea faced related to the celebration of Easter. For some time the Church had become divided about the proper observance not only of Easter itself, but also the Lenten Season and the post-Easter period leading to Pentecost. The Council deputed to the Bishopric of Alexandria the task of computing the correct dates for Easter to ensure unity of theological belief and doxological expression. While the practice of composing pastoral letters had already been established in Alexandria, Athanasius continued to notify the Church concerning Easter by sending Festal Letters throughout his entire period in office. In the first instance, we shall examine the historical background to these Pastoral Epistles. The theme of resurrection is then investigated in relation to three of Athanasius' main works - Contra Gentes, De Incarnatione and Contra Arianos (I - III). The third chapter particularises the concept of resurrection and the manner in which Athanasius perceives it within the Festal Letters themselves. This is complemented by an analysis of the doxological significance of resurrection within worship and especially Eucharistic practice. Chapter Five expresses the main theological realities that formed the foundation of Athanasius' soteriological beliefs. Central to these are the nature of the homoousion and the saving vicarious humanity of Jesus Christ. The sixth chapter concludes appropriately with a study of immortality in relation to body and soul
