Utilitarianism has recently been criticised on two counts in a recent number of Ratio. According to Terrance C. McConnell, it represents many of the acts which are ordinarily regarded as supererogatory as obligatory, and some (perhaps all) of the others as actually wrong. In support of the latter criticism, he gives two kinds of examples: cases of self-sacrifice, and cases of trivial favours. Acts of self-sacrifice performed for the sake of others’ good, but which result in a greater balance of harm over benefits than alternative acts would produce, would, he claims, normally be regarded as heroic, but are forbidden as wrong by the utilitarian: and of two alternative trivial favours, either of which would ordinarily count as supererogatory (i.e. desirable but not obligatory) the utilitarian must treat the more beneficial as an obligation, and the less beneficial alternative as unallowable. These departures from ordinary responses are considered grounds for seriously doubting the adequacy of utilitarianism.

Hollandites with compositions Ba1.2-xCsxMg1.2-x/2Ti6.8+x/2 O16, and Ba1.2-xCsxAl2.4-xTi5.6+xO16 (x=0, 0.1, 0.25) have been synthesised using a modified alkoxide/acetate precursor route. The samples have been sintered using two procedures; hot isostatic pressing and sintering at ambient pressure. X-ray powder diffraction has shown samples from both systems to form tetragonal hollandites, with little change when pressed by both methods. Cs-133 MAS NMR spectra have been recorded showing the chemical shift in Al containing samples to be ∼250ppm, and in Mg hollandites ∼175ppm and 200ppm, with little change when prepared by both methods.

It has recently been suggested that lycra garments are helpful for children with cerebral palsy (CP). Twelve children, with athetosis, ataxia, and spasticity, were fitted with lycra garments (Kendall-Camp UK Ltd). Scores on the Paediatric Evaluation of Disability Inventory (PEDI) scales were determined before and after wearing the garment for at least 6 hours a day for 6 weeks. Five children with motor problems representative of the whole group were investigated during a reach-and-grasp task by kinematic motion analysis; reflective markers were used with and without the garment. Carers were given a questionnaire concerning the practicalities of using the garments. All 12 children made improvements in at least one of the functional scales of the PEDI, and scores for the whole group showed significant gains (Wilcoxon χ2 test, self-help p<0.01; mobility p<0.5; social p<0.1). These changes were usually slight, although noticed by carers. Six children made gains of at least one scale of the caregiver assistance scores, two of the children showed losses (due to difficulties removing the garment for toileting), and four showed no change. Motion analysis indicated that (1) two children with athetosis had improved proximal stability in sitting and in smoothness of arm movements, (2) one child with ataxia had improved in proximal and distal stability, and (3) two children with spasticity had more jerky movements, although one improved in proximal stability. All children had problems in wearing the garments, including problems with toileting and incontinence of urine; the parents of only one child wanted to continue using it. Results suggest that the functional benefit of lycra garments for children with CP is mainly due to improvements in proximal stability but this should be weighed against the inconvenience and loss of independence.

The electron synchrotron ’revolution’ is barely twenty years old yet its impact on materials science is immeasurable. Fig.1 captures the essence of synchrotron radiation with the dipole magnet, which is associated with a highly collimated fan of radiation due to the centripetal acceleration of electron bunches responding to the inwardly acting Lorentz force; however dipole magnets often play a secondary role in current “third generation” synchrotrons which also utilize more advanced magnet configurations (wigglers and undulators) that are capable of producing even more brilliant sources of X-radiation. The five main attributes of synchrotron X-ray beams are:
• The X-ray beam is intense, such that up to 1012 photons per second might be incident on a sample, thus enabling measurements with excellent counting statistics and/or short collection times.
• The radiation is horizontally polarized in the plane of the electron orbit.
• The X-ray beam is highly collimated, with a typical working divergence of ∼mrads, such that there is less wastage during its passage through the optical components and a superior angular resolution in the eventual measurement.
• The radiation has a smooth continuous 'white' spectrum extending into the hard (penetrating) X-ray region, thus offering the choice of conducting experiments with white radiation or alternatively enabling a free choice of wavelength by use of a monochromator.
• Since the electrons move in bunches the synchrotron X-ray source is actually pulsed, at a frequencies in the region of 3×108 s−1.

The synthesis at high pressures ( ∼60 Kbar) and high temperatures (∼1100 °C) of the title new ruthenates has been achieved and the materials compared to the gadolinium analogue. The structure remains tetragonal (S.G. P4/mmm) and the cell parameters linearly decrease following the lanthanide contraction. Preliminary results concerning the complex magnetic properties of these materials, where superconductivity, antiferromagnetism and a superimposed ferromagnetic ordering coexist, are presented.

In the perovskite-related La/Ba/Cu oxide system, the lanthanum ions can substitute on the barium sites due to a close match in the ionic radius of the two. Thus it is possible to make a solid solution La1+xBa2-xCu3Oy where O ∼ x ≤ 0.5 and y ∼ 7. For the Ba-rich end member composition (x ∼ 0). the structure is orthorhombic. but as the La content increases and La begins to substitute on the Ba sites (disordered), the crystal symmetry changes from orthorhombic to tetragonal. In addition, the superconducting properties vary with increasing La content. In particular, the superconducting onset temperature is found to decrease linearly from 80 to 45 K over the compositional (x) range 0.0 → 0.375. In the La-rich limit (x = 0.5). 1/4 of the Ba atoms are replaced by La and superconductivity is lost. A correlation between oxygen ordering (annealing) and high Tc is observed for orthorhombic LaBa2Cu3Oy and inferred in the case of tetragonal La1.25Ba1.75Cu3Oy.
