    A status-based crisis of teacher shortages? A discussion

    The theory of status, applied by Ovenden-Hope (2022) to the current crisis of teacher shortages, helps to identify one of the underlying factors that impact teachers entering the teaching workforce in England. In this appreciative response to her paper, I argue that the structural factors that have come about with the neoliberal policy agenda of the last 40 years have impacted the status of teaching and the educative purpose, and that without a clear understanding of, and willingness to oppose, these structural factors, it is unlikely that we will solve the recruitment/retention challenge. These factors contribute to the low esteem in which teachers are held because of their perceived short period of training; public knowledge and curriculum access; the reconfiguring of teachers from knowledgeable guides to deliverers of content; and the co-option of the teaching profession as an arm of the state. The neoliberal or marketised teleology of education militates against the historic status of the teacher, and it is unlikely that teacher status will improve while they are teaching in an education system geared to the production of economically active adult

    Small-scale convection beneath the transverse ranges, California: Implications for interpretation of gravity anomalies

    Get PDF
    Tomographic inversion of upper mantle P wave velocity heterogeneities beneath southern California shows two prominent features: an east-west trending curtain of high velocity material (up to 3% fast) in the upper 250 km beneath the Transverse Ranges and a region of low velocity material (up to 4% slow) in the 100 km beneath the Salton Trough. These seismic velocity anomalies were interpreted as due to small scale convection in the mantle. Using this hypothesis and assuming that temperature and density anomalies are linearly related to seismic velocity anomalies through standard coefficients of proportionality, leads to inferred variations of approx. + or - 300 C and approx. + or - 0.03 g/cc

    ALMA view of the circumstellar environment of the post-common-envelope-evolution binary system HD101584

    We study the circumstellar evolution of the binary HD101584, consisting of a post-AGB star and a low-mass companion, which is most likely a post-common-envelope-evolution system. We used ALMA observations of the 12CO, 13CO, and C18O J=2-1 lines and the 1.3mm continuum to determine the morphology, kinematics, masses, and energetics of the circumstellar environment. The circumstellar medium has a bipolar hour-glass structure, seen almost pole-on, formed by an energetic jet, about 150 km/s. We conjecture that the circumstellar morphology is related to an event that took place about 500 year ago, possibly a capture event where the companion spiraled in towards the AGB star. However, the kinetic energy of the accelerated gas exceeds the released orbital energy, and, taking into account the expected energy transfer efficiency of the process, the observed phenomenon does not match current common-envelope scenarios. This suggests that another process must augment, or even dominate, the ejection process. A significant amount of material resides in an unresolved region, presumably in the equatorial plane of the binary system.Comment: A&A Letter, accepte
