“…The NHS has undertaken a plethora of reforms, beginning in the 1980s, but increasing in pace in the 1990s and 2000s, that devolve responsibility for care delivery to the local level, and with this bringing a greater focus on the role for local management. 63 But there has traditionally been limited empirical evidence in large samples on the relevance of management and organisational practices for hospitals, because of the inherent difficulty in measuring different inputs, and the inability to control simultaneously for hospital and patient population characteristics.…”

Medical Labour Supply and the Production of Healthcare

Medical labour markets are important because of their size and the importance of medical labour in the production of healthcare and in subsequent patient outcomes. We present a summary of important trends in the UK medical labour market, and we review the latest research on factors that determine medical labour supply and the impact of labour on patient outcomes. The topics examined include: the responsiveness of labour supply to changes in wages, regulation and other incentives; factors that determine the wide variation in physician practice and style; and the effect of teams and management quality on patient outcomes. This literature reveals that while labour supply is relatively unresponsive to changes in wages, medical personnel do react strongly to other incentives, even in the short run. This is likely to have consequences for the quality of care provided to patients. We set out a series of unanswered questions in the UK setting, including: the importance of non‐financial incentives in recruiting and retaining medical staff; how individuals can be incentivised to work in particular specialties and regions; and how medical teams can be best organised to improve care.

Using mullite (3Alz03·2SiOz)-tube type and zrOz (MgO mole fractions of 9°/o)-plug type solid electrolyte, the activities of AI in the Fe-15, 29% Ni-0.002 to 0.84% AI (mass contents in%) alloys were measured at 1873 K in an AI203 crucible, and those of Si in the Fe-13, 28%Ni-0.13 to 2.3% Si alloys were measured at 1823 K in a mullite crucible with an excess of Si02. The interaction coefficients of e~i and ,:i were determined as -0.0173 ± 0.0052 and 0.00021 ± 0.00007, respectively, and those of e~i and rs~i were determined as 0.0094 ± 0.0049 and -0.00008 ± 0.00004, respectively. The oxygen activities obtained by the EMF measurements were compared with those obtained from the contents of analyzed oxygen. The oxygen activities in the Fe-Ni-AI alloys were found to be supersaturated. The interaction coefficients of e~; and I/;; were determined as 0.0027 ± 0.0012 and 0.00012 ± 0.00004, respectively, from the contents of analyzed oxygen in Fe-Ni-fu alloys.Messung der Aktlvltaten von AI oder 51 In Fe·Ni-Leglerungen mit Mullit· und EMK·50nden auf Zr02·Basis.

Lattice-Misfit Stresses in a Circular Bi-Material Gallium-Nitride Assembly

A simple and physically meaningful analytical ( "mathematical" ) predictive model is developed using two-dimensional (planestress) theory-of-elasticity approach (TEA) for the evaluation of the effect of the circular configtiration of the substrate (wafer) on the elastic lattice-misfit (mismatch) stresses (LMS) in a semiconductor and particularly in a gallium nitride (GaN) film grown on such a substrate. The addressed stresses include (I) the inteifacial shearing stress supposedly responsible for the occurrence and growth of dislocations, for possible delaminations, and for the cohesive strength of the intermediate strain buffering material, if any, as well as (2) normal radial arid circumferential (tangential) stresses acting in the film cross-sections and responsible for the short-and long-term strength (fracture toughness) of the film. The TEA results are compared with the formulas obtained using strength-of-materials approach (SMA). This approach considers, instead of the actual circular substrate, an elongated bi-material rectangular strip of unit width and of finite length equal to the wafer diameter. The numerical example is carried out, as an illustration, for a GaN film grown on a silicon carbide (SiC) substrate. It is concluded that the SMA model is acceptable for understanding the physics of the state of stress and for the prediction of the normal stresses in the major midportion of the assembly. The SMA model underestimates, however, the maximum interfacial shearing stress at the assembly periphery and, because of the very nature of the SMA, is unable to address the circumferential stress. The developed TEA model can be used, along with the author's earlier publications and the (traditional and routine) finite-element analyses (FEA), to assess the merits and shortcomings of a particular semiconductor crystal growth (SCG) technology, as far as the level of the expected LMS are concerned, before the actual experimentation and/or fabrication is decided upon and conducted.
