Cross-cultural literacy: An American imperative

The world is becoming a global village, say the experts. Just as individuals are dependent upon and, in turn, are depended on by their family, friends, and immediate communities, so are the nations of the world becoming highly interdependent (Brademas, 1987; Horne & Masson, 1988). The more this situation comes to pass, the more important does it become that we all make ourselves cross-culturally literate--that we become knowledgeable, that is, of the political and economic systems that exist around the world and of the many different ways people have of thinking, feeling, acting, and viewing things

Reclaiming academia from post-academia

Post-academic science, driven as it is by commercialisation and market forces, is fundamentally at odds with core academic principles. Publicly-funded academics have an obligation to carry out science for the public good, a responsibility which is incompatible with the entrepreneurial ethos increasingly expected of university research by funding agencies. Is nanoscience the "first full embodiment of post-academic science"? Have many of the traditional core values of publicly-funded university science been eroded to the point where they are now "part of a scientific mythology"? And is it "morally bankrupt" to draw a distinction between "pure" and "applied" science? These claims, which were all made in a recent commentary in Nature Nanotechnology b

Particle creation and non-adiabatic transitions in quantum cosmology

The aim of this paper is to compute transitions amplitudes in quantum cosmology, and in particular pair creation amplitudes and radiative transitions. To this end, we apply a double adiabatic development to the solutions of the Wheeler-DeWitt equation restricted to mini-superspace wherein gravity is described by the scale factor $a$. The first development consists in working with instantaneous eigenstates, in $a$, of the matter Hamiltonian. The second development is applied to the gravitational part of the wave function and generalizes the usual WKB approximation. We then obtain an exact equation which replaces the Wheeler-DeWitt equation and determines the evolution, i.e. the dependence in $a$, of the coefficients of this double expansion. When working in the gravitational adiabatic approximation, the simplified equation delivers the unitary evolution of transition amplitudes occurring among instantaneous eigenstates. Upon abandoning this approximation, one finds that there is an additional coupling among matter states living in expanding and contracting universes. Moreover one has to face also the Klein paradox, i.e. the generation of backward waves from an initially forward wave. The interpretation and the consequences of these unusual features are only sketched in the present paper. Finally, the examples of pair creation and radiative transitions are analyzed in detail to establish when and how the above mentioned unitary evolution coincides with the Schr\" odinger evolution.Comment: 27 pages, Late

Quantified Aeolian dune changes on Mars derived from repeat context camera images

Aeolian systems are active across much of the surface of Mars and quantifying the activity of bedforms is important for understanding the modern and recent Martian environment. Recently, the migration rates and sand fluxes of dunes and ripples have been precisely measured using repeat High Resolution Imaging Science Experiment (HiRISE) images. However, the limited areal extent of HiRISE coverage means that only a small area can be targeted for repeat coverage. Context Camera (CTX) images, although lower in spatial resolution, have wider spatial coverage, meaning that dune migration can potentially be monitored over larger areas. We used time series, coregistered CTX images and digital elevation models to measure dune migration rates and sand fluxes at six sites: Nili Patera, Meroe Patera, two sites at Herschel crater, McLaughlin crater, and Hellespontus Montes. We observed dune displacement in the CTX images over long-term baselines (7.5–11 Earth years; 4–6 Mars years). Bedform activity has previously been measured at all these sites using HiRISE, which we used to validate our results. Our dune migration rates (0.2–1.1 m/EY) and sand fluxes (2.4–11.6 m3 m−1 EY−1) compare well to measurements made with HiRISE. The use of CTX in monitoring dune migration has advantages (wider spatial coverage, faster processing time) and disadvantages (ripples not resolved, digital elevation model dune heights may be underestimates); the future combined use of HiRISE and CTX is likely to be beneficial

Paid parental leave evaluation: Phase 2 report

Since 1 January 2011, most Australian families in which a mother was in paid employment before the birth or adoption of a child have been eligible for the new Australian Government funded Paid Parental Leave (PPL) scheme.2 The scheme provides eligible parents with up to 18 weeks of Parental Leave Pay (PLP), paid at the rate of the National Minimum Wage, following the birth or recent adoption of a child. The PPL scheme brings Australia into line with all other Organisation for Economic Cooperation and Development (OECD) countries, except the United States, in having a national scheme for paid leave available to mothers following childbirth. This report describes the results of an evaluation of the initial operation of the scheme

Parentage of Hydatidiform Moles

We were presented with the STR (short tandem repeat) profiles from two separate paternity trios. Each trio consisted of a mother, an alleged father, and products of conception (POC) that contained a hydatidiform mole but no visible fetus. In both cases, antecedent pregnancies had followed alleged sexual assaults. Mole classification and pathogenesis are described in order to explain the analyses and statistical reasoning used in each case. One mole exhibited several loci with two different paternal alleles, indicating it was a dispermic (heterozygous) mole. Maternal decidua contaminated the POC, preventing the identification of paternal obligate alleles (POAs) at some loci. The other mole exhibited only one paternal allele/locus at all loci and no maternal alleles, indicating it was a diandric and diploid (homozygous) mole. In each case, traditional calculations were used to determine paternity indices (PIs) at loci that exhibited one paternal allele/locus. PIs at mole loci with two different paternal alleles/locus were calculated from formulas first used for child chimeras that are always dispermic. Combined paternity indices in both mole cases strongly supported the paternity of each suspect.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/155886/1/jfo14291.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/155886/2/jfo14291_am.pd
