A recent review article by S. Samuel "On the Speed of Gravity and the Jupiter/Quasar Measurement" published as Int. J. Mod. Phys. D13, 1753 (2004), provides the reader with a misleading "theory" of the relativistic time delay in the general theory of relativity. Furthermore, it misquotes original publications by Kopeikin and Fomalont and Kopeikin related to the measurement of the speed of gravity by VLBI. We summarize the general relativistic principles of the Lorentz-invariant theory of the propagation of light in a time-dependent gravitational field, derive a Lorentz-invariant expression for the relativistic time delay, and finally explain why Samuel's "theory" is conceptually incorrect and confuses the speed of gravity with the speed of light.

AbstractThe following is a response to the recent review article by Girsang and colleagues (Int J Retina Vitreous. 2020;6:46), who describe concept and application of relaxing radial retinectomy for retinal detachment with advanced proliferative vitreoretinopathy. We discuss the distribution of the retinal nerve fiber layer, an aspect not touched on by the authors, and the importance of its consideration in determining visual field outcomes when performing retinectomy. Moreover, we share our clinical experience with both radial and circumferential retinectomy and discuss scenarios where the combination of both is more effective.

It is becoming increasingly evident from work carried out by various groups of research workers throughout the world (Thomas and Hill, 1949; Blackman and Wilson, 195 I ; Donald, 195 1, 1956; Black, 1955; Watson, 1956) that the amount of light energy available to herbage and crop plants is a major controlling factor in plant growth. In a recent review article Black ( 1957) has stated, "It is clear from the evidence herein reviewed that the growth of pasture species, as of other plants, is markedly dependent on the light environment, and that the quantity of light energy available rather than the intensity appears to be the important factor. Apparently the greater the quantity of light energy available up to the highest values recorded in the field, the better the growth."

This study has arisen out of the work of the Newcastle group (Kiloh and Garside, 1963; Kayet al., 1969) and that of the London group (Kendell, 1968) on the forms of depressive illness. In the present investigation, unlike those mentioned, a subjective approach was employed; that is, what the patients actually reported about themselves rather than a psychiatric appraisal of the patient was used as the data. A similar approach was employed by Pilowsky, Levine and Boulton (1969) in their taxonomic study of depression. The object of this paper is firstly, to investigate the systematic and the taxonomy of depressive phenomena; secondly to look at this taxonomy in depressive illness and non-depressive illness patients; and thirdly to investigate the psychiatrist's notion of the endogenous-reactive dichotomy within this taxonomy. Essentially the question is whether there is a continuum of depression, at one pole being reactive depression and at the other pole endogenous depression or whether these two classical diagnoses represent separate empirical entities. The former view is taken by the London workers and the latter by the Newcastle workers. In a recent review article, Eysenck (1970) favoured the binary or separate entity model, although he suggests that both views of depressive illness are over simplistic in their formulations.

Psychological Disposition

In a recent review article [this Journal, VI (1974), 345–69] Professor Berrington helpfully corrects and refines the statistics contained in Lucille Iremonger's volume, The Fiery Chariot: A Study of British Prime Ministers and the Search for Love and suggests that there may well be something in the idea that prime ministers differ systematically in their psychological make-up from the rest of the population. It is clearly the case that they have been unfortunate in their choice of parents, who have been more apt to die when the putative PM is young than is generally the case. And one cannot sensibly, in the light of theoretical evidence cited by Berrington, object to his proposal that premature bereavement may establish in the child a condition or conditions of mind and a psychological disposition that may well be relieved, made tolerable or even cured by immersion in the life-style of a professional politician. However, there are a number of points worth making about Professor Berrington's endorsement, limited though it is, of Iremonger's thesis.

Recent Review Article

In his recent review article (Sharpe, 1983) Barrie Sharpe submits two of my books (Muller, 1976, 1981) to dissection but he does so in such a carefree manner, with so many mistakes and gratuituous assumptions, that I am prompted to reply in order to set the record straight.I am first accused of not having dealt with ’religious conversion, social change and economy in [my] two books’. This is partly true forDu bon usage, and I have explained the reasons for not analysing the matrimonial changes brought about by British colonization (p. 28). It would have made too cumbersome a book and would have been beside the point. As forParenté et manage, I have dealt with ‘economy, social change and conversion’ (pp. 46–67 for economy; 99–100 on the changes in bridewealth payments for literate people; 138–40 about the introduction of reimbursement of bridewealth, for instance, but there are many more changes examined together with the influence of Christianity on marriage throughout the book). These aspects are also covered in three articles published separately: one on inter-tribal trade, another on conversion, and a third on economic change and tin mining, a topic also dealt with in the review article in question (Muller, 1972, 1974, 1980a).
