    Exploring relationships between working memory and writing: individual differences associated with gender

    Gender differences in the relationships between working memory (short-term storage and combined storage and processing) in both the visuo-spatial and verbal domains and children's alphabet transcription and text writing abilities were investigated. Data from 81 children (43 males) aged between 5;2 to 8;5 revealed no significant group differences between boys and girls in working memory or writing performance. However, individual difference analyses demonstrated variation associated with age and gender in the memory skills underpinning writing. Regression analyses revealed that verbal short-term memory abilities predicted the alphabet transcription skills of boys but not girls. Although visuo-spatial short-term memory predicted writing quality in both genders, predictors of writing fluency differed with verbal working memory skills predicting boys' writing fluency and visuo-spatial short-term memory predicting writing fluency in girls. The need to consider gender differences more critically from the perspective of individual differences in cognitive skills underpinning writing development and the strategic application of these skills during writing is discussed.

    Triggered Star Formation in a Massive Galaxy at z=3.8: 4C41.17

    Spectropolarimetric observations obtained with the W. M. Keck Telescope of the z=3.8 radio galaxy 4C41.17 show that the UV continuum emission from this galaxy, which is aligned with the radio axis, is unpolarized (P[2sigma] < 2.4%). This implies that scattered AGN light, which is generally the dominant contributor to the rest-frame UV emission in z~1 radio galaxies, is unlikely to be a major component of the UV flux from 4C41.17. The spectrum shows absorption lines that are similar to those detected in the spectra of the recently discovered population of star forming galaxies at z~2-3. A galaxian outflow may contribute partially to the low ionization absorption lines; however, the high velocity wings of the high ionization lines are unlikely to be dominated by a galaxian wind since the implied outflow mass is very large. The detection of stellar absorption lines, the shape of the SiIV profile, the unpolarized continuum, the inability of any AGN-related processes to account for the UV flux, and the similarity of the UV continuum spectra of 4C41.17 and the nearby starburst region NGC 1741B1 suggest that the UV light in 4C41.17 is dominated by young stars. If so, the implied star-formation rate is roughly 140-1100Msun/yr. We discuss the possibility that star formation in 4C41.17 was triggered by the radio source. Our data are consistent with the hypothesis that 4C41.17 is undergoing its major epoch of star formation at z~4, and that by z~1 it will have evolved to have spectral and morphological properties similar to those observed in known z~1 powerful radio galaxies.Comment: 28 pages (Latex text + figures); Accepted for publication in The Astrophysical Journal (Dec 1, 1997 issue

    A Survey of Extragalactic Faraday Rotation at High Galactic Latitude: The Vertical Magnetic Field of the Milky Way towards the Galactic Poles

    Full text link
    We present a study of the vertical magnetic field of the Milky Way towards the Galactic poles, determined from observations of Faraday rotation toward more than 1000 polarized extragalactic radio sources at Galactic latitudes |b| > 77 degs, using the Westerbork Radio Synthesis Telescope and the Australia Telescope Compact Array. We find median rotation measures (RMs) of 0.0 +/- 0.5 rad/m^2 and +6.3 +/- 0.7 rad/m^2 toward the north and south Galactic poles, respectively, demonstrating that there is no coherent vertical magnetic field in the Milky Way at the Sun's position. If this is a global property of the Milky Way's magnetism, then the lack of symmetry across the disk rules out pure dipole or quadrupole geometries for the Galactic magnetic field. The angular fluctuations in RM seen in our data show no preferred scale within the range ~ 0.1 to 25 degs. The observed standard deviation in RM of ~ 9 rad/m^2 then implies an upper limit of ~1microGauss on the strength of the random magnetic field in the warm ionized medium at high Galactic latitudes.Comment: 38 pages, 7 figures, 3 tables Accepted for publication in ApJ, Electronic versions of Tables 1 and 2 are available via email from the first autho

    The Cronobacter genus: ubiquity and diversity

    Get PDF
    Members of the Cronobacter genus (formerly Enterobacter sakazakii) have become associated with neonatal infections and in particular contaminated reconstituted infant formula. However this is only one perspective of the organism since the majority of infections are in the adult population, and the organism has been isolated from the enteral feeding tubes of neonates on non-formula diets. In recent years methods of detection from food and environmental sources have improved, though accurate identification has been problematic. The need for robust identification is essential in order to implement recent Codex Alimentarius Commission (2008) and related microbiological criteria for powdered infant formula (PIF; intended target age 0-6 months). Genomic analysis of emergent pathogens is of considerable advantage in both improving detection methods, and understanding the evolution of virulence. One ecosystem for Cronobacter is on plant material which may enable the organism to resist desiccation, adhere to surfaces, and resist some antimicrobial agents. These traits may also confer survival mechanisms of relevance in food manufacturing and also virulence mechanisms

    Comfort radicalism and NEETs: a conservative praxis

    Get PDF
    Young people who are not in education, employment or training (NEET) are construed by policy makers as a pressing problem about which something should be done. Such young people's lack of employment is thought to pose difficulties for wider society in relation to social cohesion and inclusion and it is feared that they will become a 'lost generation'. This paper(1) draws upon English research, seeking to historicise the debate whilst acknowledging that these issues have a much wider purchase. The notion of NEETs rests alongside longstanding concerns of the English state and middle classes, addressing unruly male working class youth as well as the moral turpitude of working class girls. Waged labour and domesticity are seen as a means to integrate such groups into society thereby generating social cohesion. The paper places the debate within it socio-economic context and draws on theorisations of cognitive capitalism, Italian workerism, as well as emerging theories of antiwork to analyse these. It concludes by arguing that ‘radical’ approaches to NEETs that point towards inequities embedded in the social structure and call for social democratic solutions veer towards a form of comfort radicalism. Such approaches leave in place the dominance of capitalist relations as well as productivist orientations that celebrate waged labour
