Dignity and the legal justification of age discrimination in health care

Evidence shows that age discrimination in health care is still widespread. At the same time, there has been suggestion, both in the theoretical literature and in the jurisprudence, that age is ‘different’ to other protected characteristics such as sex and race and thus that age discrimination may sometimes be permissible in circumstances in which discrimination on other grounds, such as sex or race, may not. This is chiefly because, it is argued, if a ‘complete life view’ of equality is taken, age discrimination may not produce the same distributive inequalities as does discrimination on other grounds. This thesis responds to these arguments by asking what other – dignity-related - harms, age based distinctions in health care may cause. Dignity is widely agreed to be an important normative foundation for anti-discrimination law and features prominently in judicial and ethical debate on a range of issues in medical law. It is not an easy concept to define, however. There is no legal or theoretical consensus as to its meaning and legal uses of dignity involve appeal to a range of different and sometimes conflicting concepts. Rather than advocating one particular conception of dignity, the thesis identifies the variety of meanings of dignity evident in two contexts of close relevance to the problem at hand - equality law and medical law – and considers the answers to which these different meanings may give rise. The purpose of the discussion is to contribute to a debate as to the approach that courts should take in assessing whether particular instances of age discrimination in health care can be justified. It concludes that, on several conceptions of dignity, age-based distinctions may give rise to dignity harms which cannot be ignored or discounted by taking a complete life view of equality. As a result, courts should tread carefully before adopting a starting point which assumes age to be different and should develop their approach to justification accordingly

Flight test experience and controlled impact of a large, four-engine, remotely piloted airplane

A controlled impact demonstration (CID) program using a large, four engine, remotely piloted transport airplane was conducted. Closed loop primary flight control was performed from a ground based cockpit and digital computer in conjunction with an up/down telemetry link. Uplink commands were received aboard the airplane and transferred through uplink interface systems to a highly modified Bendix PB-20D autopilot. Both proportional and discrete commands were generated by the ground pilot. Prior to flight tests, extensive simulation was conducted during the development of ground based digital control laws. The control laws included primary control, secondary control, and racetrack and final approach guidance. Extensive ground checks were performed on all remotely piloted systems. However, manned flight tests were the primary method of verification and validation of control law concepts developed from simulation. The design, development, and flight testing of control laws and the systems required to accomplish the remotely piloted mission are discussed

Nonlinear transverse cascade and two-dimensional magnetohydrodynamic subcritical turbulence in plane shear flows

We find and investigate via numerical simulations self-sustained two-dimensional turbulence in a magnetohydrodynamic flow with a maximally simple configuration: plane, noninflectional (with a constant shear of velocity) and threaded by a parallel uniform background magnetic field. This flow is spectrally stable, so the turbulence is subcritical by nature and hence it can be energetically supported just by transient growth mechanism due to shear flow nonnormality. This mechanism appears to be essentially anisotropic in spectral (wavenumber) plane and operates mainly for spatial Fourier harmonics with streamwise wavenumbers less than a ratio of flow shear to the Alfv\'{e}n speed, $k_y < S/u_A$ (i.e., the Alfv\'{e}n frequency is lower than the shear rate). We focused on the analysis of the character of nonlinear processes and underlying self-sustaining scheme of the turbulence, i.e., on the interplay between linear transient growth and nonlinear processes, in spectral plane. Our study, being concerned with a new type of the energy-injecting process for turbulence -- the transient growth, represents an alternative to the main trends of MHD turbulence research. We find similarity of the nonlinear dynamics to the related dynamics in hydrodynamic flows -- to the \emph{bypass} concept of subcritical turbulence. The essence of the analyzed nonlinear MHD processes appears to be a transverse redistribution of kinetic and magnetic spectral energies in wavenumber plane [as occurs in the related hydrodynamic flow, see Horton et al., Phys. Rev. E {\bf 81}, 066304 (2010)] and differs fundamentally from the existing concepts of (anisotropic direct and inverse) cascade processes in MHD shear flows.Comment: 19 pages, 7 figures, published in Phys.
