Our study investigates the effects of economic policy uncertainty (EPU) on firm-level innovation activities. Utilizing news-based government EPU index Baker et al. (2016) and a panel sample 213 UK largest non-financial firms over period 1999-2018, we find robust evidence that has caused substantial reduction in firms’ investment Moreover, our results further show such lower level corporate lead...

Let f be a transcendental meromorphic function and U be an invariant Baker domain of f . We use estimates for the hyperbolic metric to show that there is a relationship between the size of U and the proximity of f in U to the identity function, and illustrate this by discussing how the dynamics of transcendental entire functions of the following form vary with the parameter a: f(z) = az + bzke−...

TO THE EDITOR—We thank Drs Baker and Holtom [1] for their thoughtful comments on the low number of smear-negative, culture-positive tuberculosis cases in our study [2] and another recent study [3] of the GeneXpert MTB/RIF assay (Xpert). They astutely point out that this may have led us to underestimate the potential benefit of Xpert in low-burden settings. We agree that the incremental sensitiv...

Baker's (1915) species described in the Oriental leafhopper genus Pythamus Melichar are revised. One species, Pythamus melichari Baker 1915, is placed in a new genus, Pythochandra Wei & Webb, gen. n.. The four varieties of P. melichari described by Baker (1915, 1923) (borneensis, bilobatus, decoratus and singaporensis) are elevated to species level and placed in the new genus stat. n., comb. n....

Popliteal cysts, or Baker cysts, are considered rare in children and may exhibit particular features, as compared with adults. We studied data from 80 paediatric patients with 55 Baker cysts, examined over a period of 7 years, and correlated clinical presentation with findings on ultrasonography and MRI. Prevalence of popliteal cysts was 57% in arthritic knees, 58% with hypermobility syndrome, ...
