    Marxism: not David Storey\u27s cup of tea

    By common acknowledgement the revolution in the history of modern English drama came with John Osborne\u27s Look Back in Anger, first seen at the Royal Court Theatre, London, in May 1956. British plays in the past, according to Henry Popkin, showed mainly the upper and upper-middle classes... When some serious emotional crisis arose, their special concern was always to show their good taste and breeding by refusing to express their emotions. Look Back in Anger impressed the critics mainly because of the outspokenness of its language, its open criticism of establishment values, and its articulate, thoughtful working-class hero. The historical significance of this play is articulated by John Russell Brown, Look Back in Anger was herald of many plays that took even more liberties. A new sense of reality swept all restrictions away. John Russell Taylor summarizes that the playwrights who respond to this new aspect of realism in British theatre have two distinguishing features: ...their tremendous variety... and the fact that the great majority of them have working-class origins. Social mobility brought by the Second World War has largely destroyed social barriers in Britain, and many of the writers who have emerged from working class to middle class have felt alienation from their families. David Storey, both novelist and playwright, is a typical example

    Does Telemedicine Affect Physician Decisions? Evidence from Antibiotic Prescriptions

    Telemedicine has long been of interest to the U.S. general public. Yet, despite the advent of high-speed internet and mobile device technology, telemedicine did not reach its full potential until the COVID-19 pandemic spurred its unparalleled adoption. This sudden shift in the setting of healthcare delivery raises questions regarding possible changes in clinical decision-making. Using a unique set of patient-provider encounter data from the U.S. in 2020 and 2021, we examine the effect of telemedicine on antibiotic prescription errors for urinary tract infections. After accounting for potential endogeneity issues using provider fixed effects and an instrumental variable approach, we find a significantly lower likelihood of prescription errors with telemedicine relative to in-person encounters. We also find heterogeneous effects by a provider's patient volume and the patient-provider relationship

    A Study of Shape Memory Effect Above Ms Temperature in a Cu-Zn Alloy Using the Twisting Deformation and Electric Resistance Methods

    The shape memory effect (SME) is generally recognized to be caused by the reverse transformation of the deformed thermoelastic martensite (TEM); in a TiNi alloy, however, it has been reported that the SME is not related to the thermoelastic martensite but is caused by stress--induced martensite (SIM) [1]. The SME is mainly related to the R-phase transformation [2]

    A note on the fractional Cauchy problems with nonlocal initial conditions

    AbstractOf concern is the Cauchy problems for fractional integro-differential equations with nonlocal initial conditions. Using a new strategy in terms of the compactness of the semigroup generated by the operator in the linear part and approximating technique, a new existence theorem for mild solutions is established. An application to a fractional partial integro-differential equation with a nonlocal initial condition is also considered
