    The impact of NQT induction programmes on the enhancement of teacher expertise, professional development, job satisfaction or retention rates: a systematic review of research literature on induction

    Get PDF
    This report is the result of a preliminary study undertaken by the Induction Review Group between January and March 2003 which essentially involved a mapping exercise to identify the range and type of research studies addressing the research question, ‘How does current research characterise the impact of induction programmes on new teachers in relation to enhancing teaching expertise, professional development, job satisfaction and retention rates?’ Results of the initial in-depth review are reported in Chapter 4. The Review Group plans further refinements of the mapping exercise and other in-depth reviews drawing on it

    Dense Molecular Filaments Feeding a Starburst: ALMA Maps of CO(3-2) in Henize 2-10

    We present ALMA CO(3-2) observations at 0.3 arcsec resolution of He2-10, a starburst dwarf galaxy and possible high-z galaxy analogue. The warm dense gas traced by CO(3--2) is found in clumpy filaments that are kinematically and spatially distinct. The filaments have no preferred orientation or direction; this may indicate that the galaxy is not evolving into a disk galaxy. Filaments appear to be feeding the active starburst; the velocity field in one filament suggests acceleration onto an embedded star cluster. The relative strengths of CO(3-2) and radio continuum vary strongly on decaparsec scales in the starburst. There is no CO(3--2) clump coincident with the non-thermal radio source that has been suggested to be an AGN, nor unusual kinematics. The kinematics of the molecular gas show significant activity apparently unrelated to the current starburst. The longest filament, east of the starburst, has a pronounced shear of FWHM 40\sim40~\kms\ across its \sim50~pc width over its entire 0.5\approx 0.5 kpc length. The cause of the shear is not clear. This filament is close in projection to a `dynamically distinct' CO feature previously seen in CO(1--0). The most complex region and the most highly disturbed gas velocities are in a region 200~pc south of the starburst. The CO(3--2) emission there reveals a molecular outflow, of linewidth FWZI \sim 120-140 \kms, requiring an energy 1053 erg/s\gtrsim 10^{53} \rm~ erg/s. There is at present {\it no} candidate for the driving source of this outflow.Comment: This was revised 31 October to correct some typos and to replace Figure

    ECONOMIES OF SIZE OF A COORDINATED BIOREFINERY FEEDSTOCK HARVEST SYSTEM

    Get PDF
    The objective of this research is to determine the cost to harvest lignocellulosic biomass, such as crop residue and perennial grasses, for use as biorefinery feedstock, and to determine the potential economies of size that might result from a coordinated structure. The estimates show that substantial size economies are possible.Research and Development/Tech Change/Emerging Technologies,

    Impaired Conscious Recognition of Negative Facial Expressions in Patients with Locked-in Syndrome

    Get PDF
    The involvement of facial mimicry in different aspects of human emotional processing is widely debated. However, little is known about relationships between voluntary activation of facial musculature and conscious recognition of facial expressions. To address this issue, we assessed severely motor-disabled patients with complete paralysis of voluntary facial movements due to lesions of the ventral pons [locked-in syndrome (LIS)]. Patients were required to recognize others’ facial expressions and to rate their own emotional responses to presentation of affective scenes.LISpatientswere selectivelyimpairedin recognition of negativefacial expressions,thusdemonstratingthatthe voluntary activation of mimicry represents a high-level simulation mechanism crucially involved in explicit attribution of emotions

    The signature of dissipation in the mass-size relation: are bulges simply spheroids wrapped in a disc?

    Full text link
    The relation between the stellar mass and size of a galaxy's structural subcomponents, such as discs and spheroids, is a powerful way to understand the processes involved in their formation. Using very large catalogues of photometric bulge+disc structural decompositions and stellar masses from the Sloan Digital Sky Survey Data Release Seven, we carefully define two large subsamples of spheroids in a quantitative manner such that both samples share similar characteristics with one important exception: the 'bulges' are embedded in a disc and the 'pure spheroids' are galaxies with a single structural component. Our bulge and pure spheroid subsample sizes are 76,012 and 171,243 respectively. Above a stellar mass of ~101010^{10} M_{\odot}, the mass-size relations of both subsamples are parallel to one another and are close to lines of constant surface mass density. However, the relations are offset by a factor of 1.4, which may be explained by the dominance of dissipation in their formation processes. Whereas the size-mass relation of bulges in discs is consistent with gas-rich mergers, pure spheroids appear to have been formed via a combination of 'dry' and 'wet' mergers.Comment: Accepted for publication in MNRAS, 6 pages, 3 figure
